However, in this case, a large amount of sterilizing water is placed on the upper surface of the bowl edge portion of the toilet bowl. If a large amount of sterilizing water is placed in the toilet seat, when the user sits on the toilet seat or turns the toilet seat by hand, there is contact between the user's buttocks, hands and the sterilizing water of the water at the toilet seat. The user feels uncomfortable. Further, when a large amount of water-removing water is applied to the upper surface of the bowl edge portion of the toilet bowl, the water-repellent water on the upper surface of the bowl edge portion is dropped to the outside of the toilet bowl.

本發明是基於對上述課題的認識而完成的，其目的在於提供一種不僅在馬桶的盆部還能夠在馬桶的盆緣部以及馬桶座等的大片範圍內抑制細菌、污垢，並能夠防止除菌水與使用者的肌膚接觸以及除菌水向馬桶外滴下的馬桶座裝置以及沖廁裝置。

[用以解決課題的技術方案]The present invention has been made in view of the above problems, and an object of the present invention is to provide a method for suppressing bacteria and dirt in a wide range of a bowl portion of a toilet bowl and a toilet seat, and preventing sterilization.

Thereby, it is possible to more reliably reduce the amount of the sterilizing water that is immersed in the upper surface of the toilet seat portion and the bowl edge portion. On the other hand, by making the particle diameter of the mist of the sterilizing water discharged during the execution of the second step large, the total amount of the sterilizing water discharged in the second step can be increased. Thereby, it is possible to increase the amount of the sterilizing water in the inner wall surface of the bowl portion and the bowl portion.

在第8～第13中的任一個發明的基礎上，第14發明的沖廁裝置的特徵在於，上述控制裝置在執行上述第1步驟後執行上述第2步驟。In the flushing device according to the fourteenth aspect of the invention, the control device is configured to execute the second step after performing the first step.

根據該沖廁裝置，在使除菌水的水霧著水於馬桶座部、盆緣部的上表面的第1步驟之後，執行第2步驟。由於能夠在第2步驟的執行中使馬桶座部、盆緣部的上表面變乾，因此能夠縮短從一次噴霧模式結束到馬桶座部、盆緣部的上表面變乾為止的時間。According to the flushing device, after the first step of causing the water mist of the sterilization water to immerse in the upper surface of the toilet seat portion and the bowl edge portion, the second step is performed.

以下，參照附圖對本發明的實施方式進行說明。此外，在各附圖中，對於相同的構成要素標注相同的附圖標記並適當地省略詳細的說明。
圖1是例示出實施方式的沖廁裝置的立體圖。
圖2是例示出實施方式的沖廁裝置的一部分的剖面圖。Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, the same components are denoted by the same reference numerals, and the detailed description is omitted as appropriate.
Fig. 1 is a perspective view illustrating a toilet device of an embodiment.
Fig. 2 is a cross-sectional view showing a part of a flushing device of the embodiment.

圖1所示的沖廁裝置10具備坐式馬桶(以下為了便於說明，簡稱為“馬桶”)800和馬桶座裝置100。馬桶800具有承接汙物的凹狀的盆部801。馬桶座裝置100設置於馬桶800的上部。The toilet device 10 shown in Fig. 1 is provided with a seat toilet (hereinafter simply referred to as "toilet" for convenience of explanation) 800 and a toilet seat device 100. The toilet 800 has a concave basin portion 801 that receives dirt. The toilet seat device 100 is disposed at an upper portion of the toilet 800.

馬桶座裝置100具有外殼400、供使用者就座的馬桶座部200、以及馬桶蓋300。馬桶座部200與馬桶蓋300分別被軸支為能夠相對於外殼400開閉。圖1的狀態是馬桶座部200關閉的狀態(被放下的狀態)，且是馬桶蓋300打開的狀態(被提起的狀態)。馬桶蓋300在關閉的狀態下從上方覆蓋馬桶座部200的座面。The toilet seat device 100 has a housing 400, a toilet seat 200 for a user to seat, and a toilet lid 300. The toilet seat 200 and the toilet lid 300 are respectively pivotally supported to be openable and closable with respect to the outer casing 400. The state of FIG. 1 is a state in which the toilet seat 200 is closed (a state in which it is lowered), and is a state in which the toilet lid 300 is opened (a state in which it is lifted). The toilet lid 300 covers the seating surface of the toilet seat 200 from above in a closed state.

在外殼400的內部，內置有對就座於馬桶座部200上的使用者的人體局部(“臀部”等)進行清洗的身體清洗功能部等。另外，例如在外殼400，設置有對使用者就座於馬桶座部200這一情況進行檢測的就座感測器404。在就座感測器404檢測到就座於馬桶座部200的使用者的情況下，若使用者例如對遙控器等手動操作部500進行操作，則能夠使清洗噴嘴(以下為了便於說明，簡稱為“噴嘴”)473進入馬桶800的盆部801內。此外，在圖1所示的馬桶座裝置100中，示出了噴嘴473進入盆部801內的狀態。Inside the casing 400, a body washing function portion or the like that cleans a part of a human body ("hip" or the like) of a user seated on the toilet seat portion 200 is incorporated. Further, for example, the housing 400 is provided with a seating sensor 404 that detects that the user is seated on the toilet seat 200. When the seat sensor 404 detects the user seated in the toilet seat 200, if the user operates the manual operation unit 500 such as a remote controller, for example, the washing nozzle can be provided (hereinafter, for convenience of explanation, simply The "nozzle" 473 enters the bowl 801 of the toilet 800. Further, in the toilet seat apparatus 100 shown in Fig. 1, a state in which the nozzle 473 enters the bowl portion 801 is shown.

在噴嘴473的前端部設置有一個或者多個吐水口474。於是，噴嘴473從設置於其前端部的吐水口474噴射水，從而能夠對就座於馬桶座部200的使用者的“臀部”等進行清洗。One or a plurality of spouting ports 474 are provided at the front end portion of the nozzle 473. Then, the nozzle 473 sprays water from the water discharge port 474 provided at the front end portion thereof, and can clean the "buttock" or the like of the user seated in the toilet seat portion 200.

此外，在本申請說明書中，“上方”、“下方”、“前方”、“後方”、“左側方”以及“右側方”分別是從以使後背朝向打開的馬桶蓋300的方式就座於馬桶座部200的使用者觀察的方向。Further, in the specification of the present application, "above", "below", "front", "rear", "left side", and "right side" are respectively seated from the toilet cover 300 with the back facing toward the opening. The direction in which the user of the toilet seat 200 views.

如圖2所示，馬桶800具有設置在盆部801之上的盆緣部805。盆緣部805是形成馬桶800的上緣部的環狀部分。在盆部801內存積有存水801w。例如，若使用者利用設置於遙控器等的開關而進行馬桶清洗的操作、或者使用者從馬桶座部200站起，則執行馬桶清洗(排出盆部801內的汙物並清洗盆部801的表面的動作)。在馬桶清洗中，向盆部801內供給清洗水。例如，在圖2的例子中，從盆供水口811沿著馬桶800的上緣排出清洗水。As shown in FIG. 2, the toilet 800 has a bowl portion 805 disposed above the bowl portion 801. The bowl edge portion 805 is an annular portion that forms the upper edge portion of the toilet bowl 800. The stored water 801w is accumulated in the basin portion 801. For example, when the user performs an operation of washing the toilet with a switch provided on a remote controller or the like, or when the user stands up from the toilet seat 200, the toilet is cleaned (the dirt in the bowl portion 801 is discharged and the bowl portion 801 is cleaned). Surface action). In the toilet washing, the washing water is supplied into the bowl portion 801. For example, in the example of FIG. 2, the washing water is discharged from the basin water supply port 811 along the upper edge of the toilet 800.

盆緣部805具有上表面806和內壁面807。上表面806是與處於關閉的馬桶座部200的背面204對置的面。內壁面807是馬桶800的內壁(與盆部801的中央側面對面的壁面)中的比供清洗馬桶的清洗水流動的部分靠上方的部分。即，在本申請說明書中，盆緣部805的內壁面807是指馬桶清洗中的非清洗部。在圖2的例子中，內壁面807包括位於比彎折成擱板狀的彎折部805B靠上方的立面。The bowl edge portion 805 has an upper surface 806 and an inner wall surface 807. The upper surface 806 is the face that faces the back side 204 of the closed toilet seat 200. The inner wall surface 807 is a portion above the portion of the inner wall of the toilet 800 (the wall surface opposite to the central side surface of the bowl portion 801) that is higher than the portion where the washing water for washing the toilet flows. That is, in the specification of the present application, the inner wall surface 807 of the bowl edge portion 805 means a non-cleaning portion during toilet cleaning. In the example of Fig. 2, the inner wall surface 807 includes a façade located above the bent portion 805B bent into a shelf shape.

對於盆部801、盆緣部805的內壁面807而言，由於汙物容易直接附著，因此是污垢負荷大的部分。另外，盆部801、盆緣部805的內壁面807即便被潤濕也不易產生問題，因此也是對潤濕的允許度高的部分。The inner wall surface 807 of the bowl portion 801 and the bowl edge portion 805 is a portion where the dirt load is large because the dirt easily adheres directly. Further, the inner wall surface 807 of the bowl portion 801 and the bowl edge portion 805 is less likely to cause problems even if it is wetted, and therefore is also a portion having a high degree of allowability for wetting.

馬桶座部200、盆緣部805的上表面806相比於盆部801、盆緣部805的內壁面807，汙物難以直接附著。例如，在馬桶座部200以及盆緣部805的上表面806，會附著因碰到盆部801、存水801w而濺起的尿液、汚水。因此，馬桶座部200以及盆緣部805的上表面806是污垢負荷比較小的部分。另外，若馬桶座部200、盆緣部805的上表面806被過度潤濕，則存在除菌水與使用者的肌膚接觸、或向馬桶外滴下的可能性，因此馬桶座部200、盆緣部805的上表面806是對潤濕的允許度低的部分。The upper surface 806 of the toilet seat portion 200 and the bowl edge portion 805 is less likely to adhere directly to the inner wall surface 807 of the bowl portion 801 and the bowl edge portion 805. For example, in the upper surface 806 of the toilet seat portion 200 and the bowl edge portion 805, urine and sewage which are splashed by the bowl portion 801 and the stored water 801w are adhered. Therefore, the upper surface 806 of the toilet seat portion 200 and the bowl edge portion 805 is a portion where the dirt load is relatively small. In addition, if the upper surface 806 of the toilet seat portion 200 and the bowl edge portion 805 is excessively wetted, there is a possibility that the sterilization water contacts the skin of the user or drops outside the toilet seat, so the toilet seat portion 200 and the bowl edge The upper surface 806 of the portion 805 is the portion that is less tolerant of wetting.

圖3是例示出實施方式的馬桶座裝置的主要部位結構的方塊圖。
此外，圖3一併示出了水路系統和電氣系統的主要部位結構。
馬桶座裝置100具有電磁閥431、除菌裝置450、切換閥472、噴霧裝置481、噴嘴馬達476、噴嘴473、噴嘴清洗室478、以及流路110～113等。它們配置在外殼400內。此外，如圖24所示，它們也可以裝入於馬桶800的內部。Fig. 3 is a block diagram showing a configuration of a main part of a toilet seat device of an embodiment.

They are disposed within the outer casing 400. Further, as shown in FIG. 24, they may be incorporated in the interior of the toilet 800.

流路110是用於將從自來水管、儲水箱等未圖示的供水源供給的水向噴霧裝置481、噴嘴473等引導的流路。在流路110的上游側設置有電磁閥431。電磁閥431是能夠開閉的電磁閥，其基於來自設置於外殼400內部的控制裝置405的指令而控制水的供給。The flow path 110 is a flow path for guiding water supplied from a water supply source (not shown) such as a water pipe or a water storage tank to the spray device 481, the nozzle 473, and the like. A solenoid valve 431 is provided on the upstream side of the flow path 110. The solenoid valve 431 is an electromagnetic valve that can be opened and closed, and controls the supply of water based on an instruction from a control device 405 provided inside the casing 400.

在流路110上，在電磁閥431的下游設置有生成除菌水的除菌裝置450。除菌裝置450例如生成包含亞氯酸等的除菌水。作為除菌裝置450，例如列舉電解槽單元。電解槽單元藉由由控制裝置405進行的通電控制，對在陽極板(未圖示)與陰極板(未圖示)之間的空間(流路)流動的自來水實施電解。其中，除菌水並不限定於包含亞氯酸。例如，除菌水也可以是包含銀離子或銅離子等金屬離子的溶液、包含電解氯或臭氧等的溶液、酸性水、或者鹼性水等。除菌裝置450並不限定於電解槽，可以是能夠生成除菌水的任意的結構。On the flow path 110, a sterilization device 450 that generates sterilization water is provided downstream of the electromagnetic valve 431. The sterilization device 450 generates, for example, sterilized water containing chlorous acid or the like. As the sterilization apparatus 450, for example, an electrolytic cell unit is exemplified. The electrolytic cell unit performs electrolysis on the tap water flowing in a space (flow path) between the anode plate (not shown) and the cathode plate (not shown) by the energization control by the controller 405. Among them, the sterilizing water is not limited to containing chlorous acid. For example, the sterilizing water may be a solution containing metal ions such as silver ions or copper ions, a solution containing electrolytic chlorine or ozone, or the like, acidic water, or alkaline water. The sterilization device 450 is not limited to the electrolytic cell, and may be any structure capable of generating the sterilizing water.

在流路110上，在除菌裝置450的下游設置有切換閥472。在切換閥472的下游設置有噴嘴473、噴嘴清洗室478以及噴霧裝置481。流路110藉由切換閥472而分支成向噴嘴473引導水的流路111、向噴嘴清洗室478引導水的流路112、以及向噴霧裝置481引導水的流路113。切換閥472基於來自控制裝置405的指令，控制流路111、流路112以及流路113各自的開閉。即，切換閥472控制水朝向噴嘴473、噴嘴清洗室478以及噴霧裝置481的供給。另外，切換閥472切換向其下游供給的水的流量。On the flow path 110, a switching valve 472 is provided downstream of the sterilization device 450. A nozzle 473, a nozzle cleaning chamber 478, and a spray device 481 are disposed downstream of the switching valve 472. The flow path 110 is branched into a flow path 111 for guiding water to the nozzle 473, a flow path 112 for guiding water to the nozzle cleaning chamber 478, and a flow path 113 for guiding the water to the spray device 481 by the switching valve 472. The switching valve 472 controls opening and closing of each of the flow path 111, the flow path 112, and the flow path 113 based on an instruction from the control device 405. That is, the switching valve 472 controls the supply of water toward the nozzle 473, the nozzle cleaning chamber 478, and the spray device 481. In addition, the switching valve 472 switches the flow rate of water supplied to the downstream thereof.

噴嘴473接受來自噴嘴馬達476的驅動力，而進入馬桶800的盆部801內或者後退。即，噴嘴馬達476基於來自控制裝置405的指令使噴嘴473進退。噴嘴473在不使用時收納在外殼400內。噴嘴473在從外殼400向前方進入的狀態下，從吐水口474吐出水而對人體局部進行清洗。The nozzle 473 receives the driving force from the nozzle motor 476 and enters the bowl portion 801 of the toilet 800 or retreats. That is, the nozzle motor 476 advances and retracts the nozzle 473 based on an instruction from the control device 405. The nozzle 473 is housed in the outer casing 400 when not in use. In a state where the nozzle 473 enters from the outer casing 400, the nozzle 473 discharges water from the water discharge port 474 to clean a part of the human body.

噴嘴清洗室478藉由從設置於其內部的吐水口噴射除菌水或者自來水，而對噴嘴473的外周表面(主體)進行清洗。The nozzle cleaning chamber 478 washes the outer peripheral surface (main body) of the nozzle 473 by spraying the sterilizing water or the tap water from the water spout provided inside.

噴霧裝置481使自來水或者由除菌裝置450生成的除菌水形成水霧狀。噴霧裝置481向盆部801、盆緣部805以及馬桶座部200噴出水霧M(除菌水的水霧或者自來水的水霧)。換言之，噴霧裝置481使除菌水的水霧或者自來水的水霧著水於盆部801、盆緣部805以及馬桶座部200。此外，在本申請說明書中，“著水”是指水(除菌水或者自來水)附著於物體的表面。特別是在“直接著水”如此的情況下，意指水(除菌水或者自來水的微粒p)從空中到達物體的表面。The spray device 481 causes the tap water or the sterilizing water generated by the sterilization device 450 to form a mist. The spray device 481 discharges the water mist M (water mist of the sterilizing water or the water mist of the tap water) to the bowl portion 801, the bowl edge portion 805, and the toilet seat portion 200. In other words, the spray device 481 causes the mist of the sterilizing water or the mist of the tap water to immerse in the bowl portion 801, the bowl portion 805, and the toilet seat portion 200. Further, in the specification of the present application, "watering" means that water (sterilized water or tap water) adheres to the surface of an object. Especially in the case of "direct watering", it means that water (sterilized water or particles p of tap water) reaches the surface of the object from the air.

另外，在外殼400的內部，設置有馬桶座用馬達511(轉動裝置)、馬桶蓋用馬達512(轉動裝置)、送風裝置513以及暖風加熱器514。

送風裝置513例如是設置於外殼400內部的風扇。送風裝置513基於來自控制裝置405的指令而執行動作。例如，隨著送風裝置513的馬達的旋轉，而葉片進行旋轉。藉此，送風裝置513能夠朝向馬桶800內(例如盆部801內)送風。另外，送風裝置513也可以向就座於馬桶座部200的使用者的局部送風。暖風加熱器514對由送風裝置513朝向外殼400的外部送出的空氣進行加熱。藉此，朝向使用者的局部送出暖風，而能夠使局部乾燥。The air blowing device 513 is, for example, a fan provided inside the casing 400. The air blowing device 513 performs an operation based on an instruction from the control device 405. For example, as the motor of the air blowing device 513 rotates, the blades rotate. Thereby, the air blowing device 513 can blow air toward the inside of the toilet 800 (for example, in the bowl portion 801). Further, the air blowing device 513 may blow air to a part of the user seated in the toilet seat portion 200. The warm air heater 514 heats the air sent from the air blowing device 513 toward the outside of the casing 400. Thereby, the warm air is sent to the user's part, and the local part can be dried.

馬桶座加熱器515(乾燥裝置)例如設置於馬桶座部200的內部。馬桶座加熱器515例如具有沿著在馬桶座部200的中央形成的開口200a的周圍設置的環狀的金屬部件。藉由基於來自控制裝置405的指令而對馬桶座加熱器515進行通電，從而馬桶座加熱器515對馬桶座部200進行加熱。作為馬桶座加熱器515，例如也可以使用管加熱器、護套加熱器、鹵素加熱器、碳加熱器等。金屬部件例如由鋁、銅等構成。另外，金屬部件的形狀能夠採用片狀、絲線狀、網狀等各種形狀。The toilet seat heater 515 (drying device) is provided, for example, inside the toilet seat 200. The toilet seat heater 515 has, for example, an annular metal member provided around the opening 200a formed at the center of the toilet seat portion 200. The toilet seat heater 515 heats the toilet seat portion 200 by energizing the toilet seat heater 515 based on an instruction from the control device 405. As the toilet seat heater 515, for example, a tube heater, a sheath heater, a halogen heater, a carbon heater, or the like can also be used. The metal member is made of, for example, aluminum, copper, or the like. Further, the shape of the metal member can be various shapes such as a sheet shape, a wire shape, or a mesh shape.

控制裝置405使用從未圖示的電源電路接受電力供給的電路。例如，控制裝置405包含微型計算機等積體電路。控制裝置405基於對使用者進行檢測的感測器402(例如人體感測器403或者就座感測器404)的檢測資訊或者手動操作部500的操作資訊，對電磁閥431、除菌裝置450、切換閥472、噴嘴馬達476、送風裝置513、暖風加熱器514、馬桶座加熱器515、馬桶座用馬達511以及馬桶蓋用馬達512進行控制。The control device 405 uses a circuit that receives power supply from a power supply circuit (not shown). For example, the control device 405 includes an integrated circuit such as a microcomputer. The control device 405 is based on the detection information of the sensor 402 (for example, the human body sensor 403 or the seat sensor 404) that detects the user or the operation information of the manual operation unit 500, and the electromagnetic valve 431 and the sterilization device 450. The switching valve 472, the nozzle motor 476, the air blowing device 513, the warm air heater 514, the toilet seat heater 515, the toilet seat motor 511, and the toilet lid motor 512 are controlled.

手動操作部500是用於供使用者例如在任意時機進行除菌水的噴霧的操作部。例如，手動操作部500是具有開關或者按鈕等的遙控器，若使用者對手動操作部500進行操作，則指示除菌水的噴霧的操作資訊(訊號)被發送至控制裝置405。控制裝置405基於該操作資訊來控制除菌裝置450、噴霧裝置481。藉此，使用者藉由對手動操作部500進行操作，能夠進行除菌水的噴霧。
另外，手動操作部500也可以具有用於供使用者對馬桶座裝置100的各功能進行操作的開關、按鈕等，而不僅是除菌水的噴霧。若進行與各功能對應的操作，則其操作資訊被發送至控制裝置405，控制裝置405基於該操作資訊來控制馬桶座裝置100的各部的動作。The manual operation unit 500 is an operation unit for the user to spray the sterilization water at an arbitrary timing, for example. For example, the manual operation unit 500 is a remote controller having a switch or a button. When the user operates the manual operation unit 500, the operation information (signal) indicating the spray of the sterilizing water is transmitted to the control device 405. The control device 405 controls the sterilization device 450 and the spray device 481 based on the operation information. Thereby, the user can perform the spraying of the sterilizing water by operating the manual operation unit 500.
Further, the manual operation unit 500 may have switches, buttons, and the like for the user to operate the functions of the toilet seat device 100, and is not only a spray of the sterilizing water. When an operation corresponding to each function is performed, the operation information is transmitted to the control device 405, and the control device 405 controls the operation of each unit of the toilet seat device 100 based on the operation information.

就座感測器404能夠檢測使用者朝向馬桶座部200的就座的有無。就座感測器404對使用者的就座以及離座進行檢測。就座感測器404能夠使用微波感測器、測距感測器(紅外線投射感測器)、超音波感測器、觸動開關、電容開關(觸摸感測器)或者形變感測器。在該例中，就座感測器404使用設置於外殼400的測距感測器。The seating sensor 404 can detect the presence or absence of the seat of the user toward the toilet seat 200. The seating sensor 404 detects the sitting and leaving of the user. The seating sensor 404 can use a microwave sensor, a ranging sensor (infrared projection sensor), an ultrasonic sensor, a touch switch, a capacitive switch (touch sensor), or a deformation sensor. In this example, the seating sensor 404 uses a ranging sensor disposed in the outer casing 400.

此外，在使用觸動開關、靜電感測器以及形變感測器等接觸式感測器的情況下，將這些接觸式感測器設置於馬桶座部200。若使用者就座於馬桶座部200，則觸動開關因使用者的體重而被壓下。或者，使用者與靜電感測器接觸。或者，因使用者的體重而對形變感測器施加壓力。根據來自這些感測器的電訊號，能夠檢測到使用者的就座。Further, in the case of using a touch sensor such as a touch switch, an electrostatic sensor, and a deformation sensor, these contact sensors are disposed in the toilet seat 200. If the user is seated in the toilet seat 200, the touch switch is depressed due to the user's weight. Alternatively, the user is in contact with the electrostatic sensor. Alternatively, pressure is applied to the deformation sensor due to the user's weight. Based on the electrical signals from these sensors, the user's seating can be detected.

人體感測器403能夠對位於馬桶800的前方的使用者、即存在於從馬桶座部200向前方離開的位置的使用者進行檢測。即，人體感測器403能夠對進入廁所而接近馬桶座部200的使用者進行檢測。作為如此的人體感測器，例如能夠使用焦電感測器、微波感測器、超音波感測器或者測距感測器(紅外線投射感測器)。在該例中，人體感測器403使用設置於外殼的焦電感測器。另外，人體感測器403也可以對剛打開廁所的門進來的使用者、馬上就要進入廁所的使用者即正要進入廁所而存在於門前的使用者進行檢測。例如，在使用了微波感測器的情況下，能夠隔著廁所的門對使用者的存在進行檢測。The human body sensor 403 can detect a user located in front of the toilet 800, that is, a user present at a position away from the toilet seat 200 toward the front. That is, the human body sensor 403 can detect the user who enters the toilet and approaches the toilet seat 200. As such a human body sensor, for example, a focal inductance detector, a microwave sensor, an ultrasonic sensor, or a distance measuring sensor (infrared projection sensor) can be used. In this example, the human body sensor 403 uses a focal electrical sensor disposed in the housing. Further, the human body sensor 403 may detect the user who has just entered the door of the toilet and the user who is about to enter the toilet, that is, the user who is entering the toilet and is present in front of the door. For example, in the case where a microwave sensor is used, the presence of the user can be detected through the door of the toilet.

控制裝置405接收人體感測器403的檢測資訊(表示使用者是否存在的訊號)、就座感測器404的檢測資訊(表示使用者是否就座的訊號)，並基於接收到的檢測資訊，控制馬桶座裝置100的各部的動作。The control device 405 receives the detection information of the human body sensor 403 (the signal indicating whether the user exists), the detection information of the seat sensor 404 (the signal indicating whether the user is seated), and based on the received detection information, The operation of each part of the toilet seat apparatus 100 is controlled.

控制裝置405能夠執行便後噴霧模式、便前噴霧模式以及手動噴霧模式這三種噴霧模式。
便後噴霧模式例如是在使用者使用沖廁裝置10之後基於感測器402的檢測資訊自動地噴出除菌水的水霧的動作模式。便前噴霧模式例如是在使用者使用沖廁裝置10之前基於感測器402的檢測資訊自動地噴出除菌水或者自來水的水霧的動作模式。手動噴霧模式是基於手動操作部500的操作資訊噴出除菌水的水霧的動作模式。The control device 405 is capable of executing three spray modes of a post-spray spray mode, a pre-dial spray mode, and a manual spray mode.
The post-dose spray mode is, for example, an operation mode in which the water mist of the sterilizing water is automatically ejected based on the detection information of the sensor 402 after the user uses the flushing device 10. The pre-dose spray mode is, for example, an operation mode in which the water mist of the sterilizing water or the tap water is automatically ejected based on the detection information of the sensor 402 before the user uses the toilet device 10. The manual spray mode is an operation mode in which water mist of the sterilizing water is ejected based on the operation information of the manual operation unit 500.

圖4(a)～圖4(e)例示出實施方式的沖廁裝置的俯視圖以及立體圖。
圖4(a)表示從前方觀察沖廁裝置10的一部分的狀態。
如圖4(a)所示，噴霧裝置481、噴嘴擋板479以及送風擋板516在馬桶座裝置100設置於馬桶800的上部的狀態下，位於盆部801的後方上部。4(a) to 4(e) are a plan view and a perspective view showing a toilet device according to an embodiment.
Fig. 4 (a) shows a state in which a part of the toilet device 10 is viewed from the front.
As shown in FIG. 4(a), the spray device 481, the nozzle flapper 479, and the blower shutter 516 are located at the upper rear portion of the bowl portion 801 in a state where the toilet seat device 100 is installed at the upper portion of the toilet bowl 800.

圖4(b)放大地表示圖4(a)的一部分。此外，在圖4(b)中，為了便於觀察，省略了外殼400的位於噴霧裝置481的前方的一部分。
噴嘴擋板479被軸支為能夠相對於外殼400轉動。噴嘴473在後退到外殼400內部的狀態下，位於噴嘴擋板479的後方。在人體局部的清洗時等，噴嘴473抵接於噴嘴擋板479，藉由轉動噴嘴擋板479而打開該噴嘴擋板479，則從外殼400的內部伸出。Fig. 4(b) shows a part of Fig. 4(a) in an enlarged manner. Further, in FIG. 4(b), a portion of the outer casing 400 located in front of the spray device 481 is omitted for the sake of convenience of observation.
The nozzle flapper 479 is axially supported to be rotatable relative to the outer casing 400. The nozzle 473 is located behind the nozzle flapper 479 in a state of retreating to the inside of the outer casing 400. When the human body is partially cleaned or the like, the nozzle 473 abuts against the nozzle shutter 479, and the nozzle shutter 479 is opened by rotating the nozzle shutter 479 to protrude from the inside of the outer casing 400.

圖4(c)～圖4(e)是放大表示噴霧裝置481、噴嘴擋板479以及送風擋板516的周邊的立體圖。
送風擋板516被軸支為能夠相對於外殼400轉動。在送風擋板516的後方，配置有送風裝置513。送風擋板516覆蓋外殼400的開口516a。從送風裝置513送出的空氣通過開口516a而向馬桶800內送出。4(c) to 4(e) are enlarged perspective views showing the vicinity of the spray device 481, the nozzle shutter 479, and the blower shutter 516.
The blower baffle 516 is axially supported to be rotatable relative to the outer casing 400. A blower 513 is disposed behind the blower baffle 516. The blower baffle 516 covers the opening 516a of the outer casing 400. The air sent from the air blowing device 513 is sent out into the toilet 800 through the opening 516a.

圖4(c)表示送風裝置513停止動作的狀態，圖4(d)以及圖4(e)表示送風裝置513工作而向盆部801內送風的狀態。
如圖4(c)所示，在送風停止的狀態下，送風擋板516關閉。
如圖4(d)所示，若送風裝置513工作，則送風擋板516因從送風裝置513送出的空氣的壓力(風壓)而轉動打開。藉此，例如像箭頭A1般，送風裝置513從盆部801內的後方上部向盆部801內的前方下部送風。
在圖4(e)的狀態下，送風裝置513所送出的風量比圖4(d)的狀態多(或者風速高)。在這種情況下，送風擋板516比圖4(d)的狀態進一步轉動而打開。藉此，送風裝置513例如像箭頭A2般從盆部801內的後方上部向盆部801內的前方上部送風。4(c) shows a state in which the blower 513 is stopped, and FIGS. 4(d) and 4(e) show a state in which the blower 513 operates to blow air into the bowl 801.
As shown in FIG. 4(c), in a state where the air supply is stopped, the blower shutter 516 is closed.
As shown in FIG. 4(d), when the air blowing device 513 is operated, the air blowing dam 516 is rotated and opened by the pressure (wind pressure) of the air sent from the air blowing device 513. Thereby, for example, as in the case of the arrow A1, the air blowing device 513 blows air from the rear upper portion in the bowl portion 801 to the front lower portion in the bowl portion 801.
In the state of FIG. 4(e), the air volume sent by the air blowing device 513 is larger than the state of FIG. 4(d) (or the wind speed is high). In this case, the blower shutter 516 is further rotated to open than the state of Fig. 4(d). Thereby, the air blowing device 513 blows air from the rear upper portion in the bowl portion 801 to the front upper portion in the bowl portion 801, for example, like the arrow A2.

如此，從送風裝置513送出的風的方向因送風擋板516而變化。換言之，送風裝置513能夠根據風量(風速)來控制送風方向。也可以使從噴霧裝置481噴出的水霧搭乘由來自送風裝置513的送風而產生的氣流，而控制水霧所著水的範圍以及各範圍內的水霧的著水量(在各範圍內著水的除菌水或者自來水的量)。As described above, the direction of the wind sent from the air blowing device 513 changes due to the blower shutter 516. In other words, the air blowing device 513 can control the air blowing direction in accordance with the air volume (wind speed). The water mist sprayed from the spray device 481 can be used to control the range of the water covered by the water mist and the amount of water sprayed in each range by the water mist generated by the air blown from the air blower 513 (water in each range) The amount of sterilizing water or tap water).

圖5(a)～圖5(c)是例示出實施方式的另一沖廁裝置的立體圖。
在該例中，在噴霧裝置481的前方設置有水霧擋板482。水霧擋板482在關閉的狀態下覆蓋噴霧裝置481的前方的至少一部分。例如，水霧擋板482在關閉的狀態下覆蓋圖6中稍後進行敘述的盤481b的前方。5(a) to 5(c) are perspective views illustrating another toilet device of the embodiment.
In this example, a water mist baffle 482 is provided in front of the spray device 481. The water mist baffle 482 covers at least a portion of the front side of the spray device 481 in a closed state. For example, the water mist baffle 482 covers the front side of the disk 481b which will be described later in FIG. 6 in a closed state.

水霧擋板482例如相對於噴嘴擋板479固定，與噴嘴擋板479聯動。藉由噴嘴擋板479的打開，水霧擋板482也打開，藉由噴嘴擋板479的關閉，水霧擋板482也關閉。The water mist baffle 482 is fixed, for example, with respect to the nozzle flapper 479, and interlocks with the nozzle flapper 479. By the opening of the nozzle flapper 479, the water mist baffle 482 is also opened, and by the closing of the nozzle flapper 479, the water mist baffle 482 is also closed.

圖5(b)以及圖5(c)放大表示噴嘴擋板479以及水霧擋板482的周邊。圖5(b)是噴嘴473後退到外殼400的內部的狀態。此時，噴嘴擋板479處於關閉的狀態，其覆蓋噴嘴473的前方。另外，水霧擋板482處於關閉的狀態，其覆蓋噴霧裝置481的至少一部分的前方。5(b) and 5(c) show the vicinity of the nozzle flapper 479 and the water mist baffle 482 in an enlarged manner. FIG. 5(b) shows a state in which the nozzle 473 is retracted to the inside of the casing 400. At this time, the nozzle flapper 479 is in a closed state, which covers the front of the nozzle 473. In addition, the water mist baffle 482 is in a closed state, which covers the front of at least a portion of the spray device 481.

在不使用噴霧裝置481時，如圖5(b)所示，利用水霧擋板482從盆部801側隱藏噴霧裝置481。藉此，能夠防止尿液、污垢附著於噴霧裝置481。When the spray device 481 is not used, as shown in FIG. 5(b), the spray device 481 is hidden from the side of the bowl portion 801 by the water mist baffle 482. Thereby, it is possible to prevent urine and dirt from adhering to the spray device 481.

圖5(c)是噴嘴473向前方伸出而轉動噴嘴擋板479的狀態。此時的噴嘴473向前方伸出的距離，也可以比人體局部清洗時向前方伸出的距離短。例如，噴嘴473的前端與噴嘴擋板479抵接。另外，在圖5(c)中，水霧擋板482與噴嘴擋板479一同轉動而打開。噴霧裝置481的一部分(盤481b)向盆部801側露出。藉此，噴霧裝置481能夠朝向盆部801噴出水霧。此外，例如參照圖23稍後進行敘述般，也可以不設置水霧擋板482而是將噴霧裝置481配置於外殼400內。Fig. 5 (c) shows a state in which the nozzle 473 is extended forward and the nozzle shutter 479 is rotated. The distance at which the nozzle 473 protrudes forward in this case may be shorter than the distance extended forward from the human body during partial cleaning. For example, the front end of the nozzle 473 abuts against the nozzle flapper 479. Further, in FIG. 5(c), the water mist dam 482 is rotated together with the nozzle shutter 479 to be opened. A part of the spray device 481 (disc 481b) is exposed to the side of the bowl portion 801. Thereby, the spray device 481 can spray water mist toward the bowl portion 801. Further, for example, as will be described later with reference to FIG. 23, the spray device 481 may be disposed in the outer casing 400 without providing the water mist baffle 482.

圖6(a)～圖6(c)是例示出實施方式的噴霧裝置的示意圖。
圖6(a)是噴霧裝置481的立體圖，圖6(b)是噴霧裝置481的側視圖。
噴霧裝置481具有馬達481a和連接在馬達481a的下方的盤481b。馬達481a的旋轉由控制裝置405控制。若馬達481a旋轉，則旋轉驅動力被傳遞至盤481b，從而盤481b旋轉。6(a) to 6(c) are schematic views illustrating a spray device according to an embodiment.
Fig. 6(a) is a perspective view of the spray device 481, and Fig. 6(b) is a side view of the spray device 481.
The spray device 481 has a motor 481a and a disk 481b connected below the motor 481a. The rotation of the motor 481a is controlled by the control device 405. When the motor 481a is rotated, the rotational driving force is transmitted to the disk 481b, so that the disk 481b is rotated.

如圖6(b)所示，向盤481b的上表面供給水W(自來水或者由除菌裝置450生成的除菌水)。藉由在盤481b的旋轉過程中供給水W，從而噴霧裝置481使水W形成水霧狀而噴霧。此外，在該例中，盤481b是平坦的圓板狀，但也可以適當地設置凹凸或者使用圓錐形狀或球體。As shown in FIG. 6(b), water W (tap water or sterilizing water generated by the sterilization device 450) is supplied to the upper surface of the disk 481b. By supplying the water W during the rotation of the disk 481b, the spray device 481 causes the water W to form a mist and spray. Further, in this example, the disk 481b has a flat disk shape, but it is also possible to appropriately provide irregularities or use a conical shape or a sphere.

圖6(c)是從上方觀察盤481b的一部分的放大圖。滴到處於旋轉的盤481b的上表面的水W因離心力而在盤481b上以膜狀擴展，並從盤481b放射出去。此時，水W從盤481b的邊緣附近保持膜狀地***、或者在成為絲狀後***，之後成為微粒p(水霧)。根據盤481b的旋轉速度、即馬達481a的旋轉速度，能夠控制水霧的粒徑(微粒p的直徑)。旋轉速度越高，水霧的粒徑就越小。例如，適當地使用旋轉速度為1000(rotation per minute：rpm)左右的低速旋轉、旋轉速度為10000rpm左右的中速旋轉、或者旋轉速度為20000rpm左右的高速旋轉，從而得到希望的粒徑。另外，藉由調整從供水口481c向噴霧裝置481供給的水W的流量，也能夠控制水霧的粒徑。Fig. 6(c) is an enlarged view of a portion of the disk 481b as viewed from above. The water W dropped onto the upper surface of the rotating disk 481b is expanded in a film shape on the disk 481b by centrifugal force, and is radiated from the disk 481b. At this time, the water W is split in a film shape from the vicinity of the edge of the disk 481b, or splits after being in a filament shape, and then becomes fine particles p (water mist). The particle diameter of the water mist (diameter of the fine particles p) can be controlled in accordance with the rotational speed of the disk 481b, that is, the rotational speed of the motor 481a. The higher the rotation speed, the smaller the particle size of the water mist. For example, a low-speed rotation having a rotation speed of about 1000 (rotation per minute: rpm), a medium-speed rotation having a rotation speed of about 10,000 rpm, or a high-speed rotation at a rotation speed of about 20,000 rpm can be suitably used to obtain a desired particle diameter. Further, by adjusting the flow rate of the water W supplied from the water supply port 481c to the spray device 481, the particle size of the water mist can be controlled.

此外，在本申請說明書中，粒徑是指在著水於沖廁裝置10之前的存在於空中的微粒p的粒徑，使用索特爾(Sauter)平均粒徑(總體積/總表面積)。對於本申請說明書中的“粒徑”的測定方法，參照圖22稍後進行敘述。另外，水霧是指粒徑在10微米(μm)以上且300μm以下的範圍。若水霧的粒徑不足10μm，則會導致潤濕盆部801、盆緣部805、馬桶座部200等對象部位需要長的時間。另外，在使用了包含亞氯酸的除菌水的情況下，若水霧的粒徑不足10μm，則水霧中的亞氯酸的濃度容易衰減，除菌性能容易降低。另一方面，若水霧的粒徑大於300μm，則水霧難以擴散，難以大範圍地噴出水霧。另外，在以下的說明中，大粒徑的水霧是指粒徑在100μm以上且300μm以下、較佳為在150μm以上且300μm以下的範圍的水霧，中粒徑的水霧是指粒徑在50μm以上且200μm以下、較佳為在60μm以上且150μm以下的範圍的水霧，小粒徑的水霧是指粒徑在10μm以上且100μm以下、較佳為在10μm以上且60μm以下的範圍的水霧。Further, in the specification of the present application, the particle diameter refers to the particle diameter of the particles p existing in the air before the water is flushed to the flushing device 10, and the Sauter average particle diameter (total volume/total surface area) is used. The method of measuring the "particle diameter" in the specification of the present application will be described later with reference to FIG. Further, the water mist means a particle diameter of 10 μm or more and 300 μm or less. When the particle diameter of the water mist is less than 10 μm, it takes a long time for the target portion such as the wetted bowl portion 801, the bowl edge portion 805, and the toilet seat portion 200. In addition, when the sterilizing water containing chlorous acid is used, if the particle size of the water mist is less than 10 μm, the concentration of chlorous acid in the water mist is likely to be attenuated, and the sterilization performance is likely to be lowered. On the other hand, when the particle diameter of the water mist is more than 300 μm, the water mist is hard to be diffused, and it is difficult to discharge the water mist in a wide range. In the following description, the water mist having a large particle diameter means a water mist having a particle diameter of 100 μm or more and 300 μm or less, preferably 150 μm or more and 300 μm or less, and the water mist of the medium particle diameter means a particle diameter. In the water mist of 50 μm or more and 200 μm or less, preferably 60 μm or more and 150 μm or less, the water mist having a small particle diameter means a particle diameter of 10 μm or more and 100 μm or less, preferably 10 μm or more and 60 μm or less. Water mist.

圖7(a)以及圖7(b)是例示出實施方式的噴霧裝置的盤的俯視圖。
圖7(a)以及圖7(b)表示從上方觀察處於旋轉的盤481b的樣子。在圖7(a)的例子中，向盤481b供給水W的供水口481c的數量為一個。該情況下，在接近供水口481c的區域，當所供給的水W的水膜在盤481b上變薄之前，水W從盤481b放射出去。因此，如圖7(a)所示，在噴霧裝置481的周圍，水霧的粒徑產生偏差。即，產生水霧的粒徑比較大的區域R1、水霧的粒徑為中間程度的區域R2、以及水霧的粒徑比較小的區域R3。另外，與水霧的粒徑對應地，流量(每單位時間噴出的水霧的量)也產生偏差。即，在區域R1流量多，在區域R2流量為中間程度，在區域R3流量小。7(a) and 7(b) are plan views illustrating a disk of the spray device of the embodiment.
Fig. 7 (a) and Fig. 7 (b) show a state in which the disk 481b that is rotating is viewed from above. In the example of Fig. 7(a), the number of the water supply ports 481c for supplying the water W to the disk 481b is one. In this case, in the region close to the water supply port 481c, the water W is radiated from the disk 481b before the water film of the supplied water W is thinned on the disk 481b. Therefore, as shown in FIG. 7(a), the particle size of the water mist varies around the spray device 481. In other words, a region R1 in which the particle diameter of the water mist is relatively large, a region R2 in which the particle diameter of the water mist is intermediate, and a region R3 in which the particle diameter of the water mist is relatively small is generated. Further, the flow rate (the amount of water mist ejected per unit time) also varies depending on the particle diameter of the water mist. That is, the flow rate is large in the region R1, the flow rate in the region R2 is intermediate, and the flow rate in the region R3 is small.

因此，例如根據供水口481c的位置、盤481b的旋轉方向(順時針或者逆時針)，能夠調整從噴霧裝置481朝向馬桶800內噴出的水霧的粒徑、流量、方向等。藉此，也可以控制從噴霧裝置481噴出的水霧所著水的範圍、以及各範圍內的水霧的著水量。另外，也可以在盤481b的周圍適當地設置對噴出水霧的方向進行控制的蓋等。Therefore, for example, according to the position of the water supply port 481c and the rotation direction of the disk 481b (clockwise or counterclockwise), the particle size, flow rate, direction, and the like of the water mist sprayed from the spray device 481 toward the toilet 800 can be adjusted. Thereby, it is also possible to control the range of the water which is sprayed from the spray device 481 and the amount of the water mist in each range. Further, a cover or the like that controls the direction in which the water mist is ejected may be appropriately provided around the disk 481b.

另外，供水口481c的數量並不限定於一個，也可以設置有多個供水口481c。例如，在圖7(b)中，設置有4個供水口481c。供水口481c在從盤481b的中心觀察時每隔90°配置。藉由如此將多個供水口481c沿著盤外周大致等間隔地配置，從而能夠在噴霧裝置481的周圍，抑制水霧的粒徑、流量的偏差，能夠進行均勻的噴霧。Further, the number of the water supply ports 481c is not limited to one, and a plurality of water supply ports 481c may be provided. For example, in Fig. 7(b), four water supply ports 481c are provided. The water supply port 481c is disposed every 90° when viewed from the center of the disk 481b. By arranging the plurality of water supply ports 481c at substantially equal intervals along the outer circumference of the disk, the particle size and the flow rate of the water mist can be suppressed around the spray device 481, and uniform spraying can be performed.

噴霧裝置481在馬桶座裝置100設置於馬桶800的上部的狀態下，配置於比馬桶座部200靠下方的位置(參照圖2)，並向馬桶800內噴出水霧。在此，噴霧裝置481配置於比馬桶座部200靠下方的狀態是指：噴霧裝置481的至少一部分(該例中為盤481b)比馬桶座部200靠下方。藉此，從比馬桶座部200靠下方的部位朝馬桶800內噴出自來水或者除菌水的水霧。In a state in which the toilet seat device 100 is installed on the upper portion of the toilet 800, the spray device 481 is disposed below the toilet seat portion 200 (see FIG. 2), and sprays water mist into the toilet 800. Here, the state in which the spray device 481 is disposed below the toilet seat portion 200 means that at least a part of the spray device 481 (in this example, the disk 481b) is located below the toilet seat portion 200. Thereby, the water mist of the tap water or the sterilizing water is ejected from the part below the toilet seat part 200 toward the toilet 800.

此外，在實施方式中，噴霧裝置並不限定於圖6以及圖7中說明的裝置。例如，作為噴霧裝置，也可以使用超音波霧化裝置。超音波霧化裝置藉由向液體照射超音波，從而將液體形成為水霧狀。另外，例如作為噴霧裝置，也可以使用雙流體噴嘴。雙流體噴嘴同時噴射氣體和液體，從而將液體形成為水霧狀。但是，在使用圖6以及圖7中說明的裝置的情況下，具有容易利用送風裝置513控制噴霧範圍的優點。另外，堵塞的風險也低，也不需要壓縮機等附屬裝置。Further, in the embodiment, the spray device is not limited to the devices described in FIGS. 6 and 7. For example, as the spray device, an ultrasonic atomization device can also be used. The ultrasonic atomizing device forms a liquid into a mist by irradiating a liquid with an ultrasonic wave. Further, for example, as a spray device, a two-fluid nozzle can also be used. The two-fluid nozzle simultaneously ejects gas and liquid to form the liquid into a mist. However, in the case of using the apparatus described in FIGS. 6 and 7, there is an advantage that the blowing range can be easily controlled by the air blowing device 513. In addition, the risk of clogging is low, and an accessory such as a compressor is not required.

參照圖8～圖11對便後噴霧模式以及手動噴霧模式下的馬桶座裝置100的動作的例子進行說明。An example of the operation of the toilet seat apparatus 100 in the post-spray spray mode and the manual spray mode will be described with reference to Figs. 8 to 11 .

圖8(a)以及圖8(b)是例示出實施方式的馬桶座裝置的便後噴霧模式以及手動噴霧模式下的動作的示意圖。
控制裝置405在一次噴霧模式(一次便後噴霧模式或者一次手動噴霧模式)中，執行第1步驟和第2步驟。圖8(a)例示出第1步驟，圖8(b)例示出第2步驟。8(a) and 8(b) are schematic views exemplifying the operation in the post-spray mode and the manual spray mode of the toilet seat device of the embodiment.
The control device 405 executes the first step and the second step in the one-time spray mode (one-time post-spray mode or one-time manual spray mode). Fig. 8(a) illustrates the first step, and Fig. 8(b) illustrates the second step.

如圖8(a)所示，第1步驟在使噴霧裝置481工作而使除菌水的水霧向馬桶800內噴出的狀態下，使送風裝置513工作而產生第1上升氣流U1。第1上升氣流U1為能夠使除菌水的水霧向馬桶座部200側上升的氣流。As shown in Fig. 8 (a), in the first step, when the spray device 481 is operated to discharge the mist of the sterilizing water into the toilet 800, the air blowing device 513 is operated to generate the first ascending airflow U1. The first ascending airflow U1 is an airflow that allows the mist of the sterilizing water to rise toward the toilet seat 200 side.

如圖8(b)所示，第2步驟在使噴霧裝置481工作而使除菌水的水霧向馬桶800內噴出的狀態下，不使送風裝置513產生第1上升氣流U1而不使除菌水的水霧向馬桶座部200側上升。As shown in FIG. 8(b), in the second step, when the spray device 481 is operated to discharge the mist of the sterilizing water into the toilet 800, the air blowing device 513 is not caused to generate the first ascending airflow U1. The mist of the bacteria water rises toward the toilet seat portion 200 side.

根據如此的結構，從比馬桶座部200靠下方的部位噴出的除菌水的水霧，在第1步驟中藉由第1上升氣流U1向馬桶座部200側上升，從而向馬桶座部200、盆緣部805的上表面806著水。另一方面，從比馬桶座部200靠下方的部位噴出的除菌水的水霧在第2步驟中不因第1上升氣流U1而向馬桶座部側上升，而是向盆部801、盆緣部805的內壁面807著水。藉此，能夠利用單一的噴霧裝置418，使除菌水的水霧不僅著水於馬桶800的盆部801，還著水於盆緣部805的上表面806、馬桶座部200。因此，不僅在馬桶800的盆部801還能夠在馬桶800的盆緣部805以及馬桶座部200等的大片範圍內抑制細菌、污垢。另外，藉由使用單一的噴霧裝置481，能夠實現馬桶座裝置100的小型化。According to such a configuration, the mist of the sterilizing water discharged from the portion below the toilet seat portion 200 rises toward the toilet seat portion 200 by the first ascending airflow U1 in the first step, and the toilet seat portion 200 is moved toward the toilet seat portion 200. The upper surface 806 of the bowl portion 805 is filled with water. On the other hand, the water mist of the sterilizing water discharged from the portion below the toilet seat portion 200 does not rise toward the toilet seat portion by the first ascending air current U1 in the second step, but is directed to the bowl portion 801 and the basin. The inner wall surface 807 of the edge portion 805 is filled with water. Thereby, the single spray device 418 can make the water mist of the sterilizing water not only water the bowl portion 801 of the toilet 800 but also the upper surface 806 of the bowl edge portion 805 and the toilet seat portion 200. Therefore, not only the bowl portion 801 of the toilet bowl 800 but also the bacteria and dirt can be suppressed in a wide range of the bowl edge portion 805 of the toilet bowl 800 and the toilet seat portion 200. Further, by using a single spray device 481, the size of the toilet seat device 100 can be reduced.

此外，第2步驟中“不使除菌水的水霧向馬桶座部側上升”的範圍，不僅包括全部水霧均不上升的情況，還可以包括微量的水霧上升的情況。例如，第2步驟中向馬桶座部側上升的水霧的量，比第1步驟中向馬桶座部側上升的水霧的量少。但是，在第2步驟中，著水於馬桶座部200、盆緣部的上表面806以及馬桶蓋300的除菌水的量，較佳為盡可能少，例如較佳為零。In addition, in the range of "the water mist of the sterilization water does not rise toward the toilet seat side" in the second step, not only the case where all the water mist does not rise, but also a case where a small amount of water mist rises may be included. For example, the amount of water mist that rises toward the toilet seat side in the second step is smaller than the amount of water mist that rises toward the toilet seat side in the first step. However, in the second step, the amount of the sterilizing water that is immersed in the toilet seat portion 200, the upper surface 806 of the bowl edge portion, and the toilet lid 300 is preferably as small as possible, for example, preferably zero.

另外，控制裝置405執行第1步驟的時機與控制裝置405執行第2步驟的時機不同。藉由在不同的時機執行產生能夠使除菌水的水霧向馬桶座部200側上升的第1上升氣流U1的第1步驟、和不產生第1上升氣流U1而不使除菌水的水霧向馬桶座部200側上升的第2步驟，能夠任意地控制除菌水在盆部801處的著水量、除菌水在盆緣部805的上表面處的著水量、以及除菌水在馬桶座部200處的著水量。Further, the timing at which the control device 405 executes the first step is different from the timing at which the control device 405 executes the second step. The first step of generating the first ascending airflow U1 capable of causing the mist of the sterilizing water to rise toward the toilet seat portion 200 and the water not generating the first ascending airflow U1 without generating the sterilizing water are executed at different timings. In the second step in which the mist rises toward the toilet seat portion 200, the amount of water of the sterilizing water at the bowl portion 801, the amount of water of the sterilizing water at the upper surface of the bowl portion 805, and the sterilizing water can be arbitrarily controlled. The amount of water at the toilet seat 200.

並且，控制裝置405對噴霧裝置481進行控制以使第1步驟中噴出的除菌水的水霧的總量(g)比第2步驟中噴出的除菌水的水霧的總量(g)少。藉此，著水於馬桶座部200以及盆緣部805的上表面806的除菌水的量比較少，著水於盆部801以及盆緣部805的內壁面807的除菌水的量比較多。藉由使大量的除菌水的水霧著水於污垢負荷大且對沾濕的允許度高的盆部801以及內壁面807，從而能夠抑制細菌、污垢的產生。藉由減少除菌水在污垢負荷小且對沾濕的允許度低的馬桶座部200以及盆緣部805的上表面806的著水量，藉此既能夠抑制細菌、污垢，又能夠在短時間內使馬桶座部200以及盆緣部805的上表面806變乾。藉此，能夠防止除菌水與使用者的肌膚接觸、或者向馬桶外滴下。Further, the controller 405 controls the spray device 481 such that the total amount (g) of the water mist of the sterilizing water discharged in the first step is greater than the total amount of the water mist (g) of the sterilizing water sprayed in the second step. less. Thereby, the amount of the sterilizing water that is immersed in the upper surface 806 of the toilet seat portion 200 and the rim portion 805 is relatively small, and the amount of the sterilizing water in the pelvic portion 801 and the inner wall surface 807 of the rim portion 805 is compared. many. By causing a large amount of water of the sterilizing water to immerse in the bowl portion 801 and the inner wall surface 807 having a large dirt load and high allowable humidity, it is possible to suppress the generation of bacteria and dirt. By reducing the amount of water in the toilet seat 200 and the upper surface 806 of the bowl portion 805, which has a small dirt load and a low allowable degree of wetness, the bacteria and dirt can be suppressed and the short-time can be reduced. The upper surface 806 of the toilet seat portion 200 and the bowl edge portion 805 is dried. Thereby, it is possible to prevent the sterilizing water from coming into contact with the skin of the user or dropping it to the outside of the toilet.

此外，水霧的總量是指在一次噴霧模式(一次便後噴霧模式或者一次手動噴霧模式)中噴霧裝置481所噴出的水霧的總量。在一次噴霧模式中，噴霧裝置481既可以連續地噴出水霧，也可以間斷地噴出水霧。另外，對於第1步驟中的水霧的總量以及第2步驟中的水霧的總量，例如能夠藉由調整盤481b的旋轉速度、向噴霧裝置481供給的除菌水的流量等來控制。Further, the total amount of water mist refers to the total amount of water mist sprayed by the spray device 481 in one spray mode (one spray mode or one manual spray mode). In the one-spray mode, the spray device 481 can continuously eject the water mist or intermittently eject the water mist. In addition, the total amount of the water mist in the first step and the total amount of the water mist in the second step can be controlled, for example, by adjusting the rotation speed of the disk 481b, the flow rate of the sterilization water supplied to the spray device 481, and the like. .

例如，控制裝置405對噴霧裝置481進行控制以使第2步驟的執行中噴出的除菌水的水霧的粒徑，比第1步驟的執行中噴出的除菌水的水霧的粒徑大。例如，如圖8的(a)所示，在第1步驟的執行中，噴霧裝置481產生小粒徑的第1水霧M1。第1水霧M1的粒徑(除菌水的微粒p1的直徑)為能夠藉由第1上升氣流U1向馬桶座部200側上升的粒徑。另外，例如，如圖8的(b)所示，在第2步驟的執行中，噴霧裝置481產生中粒徑的第2水霧M2。第2水霧M2的粒徑(除菌水的微粒p2的直徑)比第1水霧M1的粒徑大。For example, the control device 405 controls the spray device 481 so that the particle diameter of the water mist of the sterilizing water discharged during the execution of the second step is larger than the particle diameter of the water mist of the sterilizing water sprayed during the execution of the first step. . For example, as shown in FIG. 8( a ), in the execution of the first step, the spray device 481 generates the first water mist M1 having a small particle diameter. The particle diameter of the first water mist M1 (the diameter of the fine particles p1 of the sterilizing water) is a particle diameter that can be raised toward the toilet seat portion 200 side by the first ascending air current U1. Further, for example, as shown in FIG. 8(b), in the execution of the second step, the spray device 481 generates the second water mist M2 having the medium particle diameter. The particle diameter of the second water mist M2 (the diameter of the fine particles p2 of the sterilizing water) is larger than the particle diameter of the first water mist M1.

藉由減小第1步驟的執行中噴出的除菌水的水霧的粒徑，能夠減少第1步驟中噴出的除菌水的總量。藉此，能夠更確實地減少著水於馬桶座部200、盆緣部805的上表面806的除菌水的量。另一方面，藉由增大第2步驟的執行中噴出的除菌水的水霧的粒徑，能夠增大第2步驟中噴出的除菌水的總量。藉此，能夠增大著水於盆部801以及盆緣部805的內壁面807的除菌水的量。By reducing the particle size of the water mist of the sterilizing water sprayed during the execution of the first step, the total amount of the sterilizing water sprayed in the first step can be reduced. Thereby, the amount of the sterilizing water that is immersed in the upper surface 806 of the toilet seat portion 200 and the bowl edge portion 805 can be more reliably reduced. On the other hand, by increasing the particle size of the water mist of the sterilizing water sprayed during the execution of the second step, the total amount of the sterilizing water sprayed in the second step can be increased. Thereby, the amount of the sterilizing water in which the water is applied to the inner wall surface 807 of the bowl portion 801 and the bowl edge portion 805 can be increased.

另外，例如，控制裝置405在第2步驟中停止送風裝置513的工作而不進行送風。藉此，能夠更確實地防止在第2步驟中除菌水的水霧向馬桶座部200側上升。Further, for example, the control device 405 stops the operation of the air blowing device 513 in the second step without performing air blowing. Thereby, it is possible to more reliably prevent the water mist of the sterilizing water from rising toward the toilet seat portion 200 side in the second step.

另外，控制裝置405也可以在第2步驟中使送風裝置513工作而產生第2上升氣流U2。第2上升氣流U2的流速比第1上升氣流U1的流速低，第2步驟中的水霧不因第2上升氣流U2而向馬桶座部200側上升。利用第2上升氣流U2，能夠使水霧不向馬桶座部200側上升而是向水平方向或者下方擴散。藉此，能夠使除菌水著水於馬桶800內的更大的範圍。Further, in the second step, the control device 405 may operate the air blowing device 513 to generate the second ascending airflow U2. The flow velocity of the second ascending airflow U2 is lower than the flow velocity of the first ascending airflow U1, and the water mist in the second step does not rise toward the toilet seat 200 side due to the second ascending airflow U2. By the second ascending airflow U2, the water mist can be diffused in the horizontal direction or downward without rising toward the toilet seat portion 200 side. Thereby, the sterilizing water can be made to immerse in a larger range in the toilet 800.

另外，噴霧裝置481使除菌水的水霧在俯視觀察時以放射狀噴霧。放射狀是指水霧所存在的範圍隨著從噴霧裝置481離開而變寬的狀態。例如，在俯視觀察時，朝向從盤481b的中心離開的所有方向噴出水霧。Further, the spray device 481 sprays the mist of the sterilizing water in a radial direction in a plan view. The radial shape refers to a state in which the range in which the water mist exists is widened as it goes away from the spray device 481. For example, in a plan view, water mist is ejected in all directions away from the center of the disk 481b.

由於第1步驟中的水霧(第1水霧M1)為放射狀，所以能夠使水霧搭乘整個第1上升氣流U1向馬桶座部200、盆緣部805的上表面806等的大片範圍著水。另外，由於第2步驟中的水霧(第2水霧M2)為放射狀，所以即便水霧未搭乘氣流，也能夠使水霧向盆部801、盆緣部805的內壁面807等馬桶800內的大片範圍著水。Since the water mist (the first water mist M1) in the first step is radial, the water mist can ride the entire first ascending airflow U1 to a large range of the toilet seat portion 200 and the upper surface 806 of the bowl edge portion 805. water. In addition, since the water mist (second water mist M2) in the second step is radial, the water mist can be applied to the toilet bowl 800 such as the bowl portion 801 and the inner wall surface 807 of the bowl edge portion 805 even if the water mist does not take the air flow. The large area inside is covered with water.

其中，對於水霧(第1水霧M1以及第2水霧M2)的擴張方式等，能夠根據盤481b的旋轉速度、配置、形狀、向盤481b供水的供水口481c的位置等來進行調整。In addition, the expansion method of the water mist (the first water mist M1 and the second water mist M2) can be adjusted according to the rotational speed, the arrangement, the shape, the position of the water supply port 481c that supplies water to the disk 481b, and the like.

圖9(a)以及圖9(b)是例示出實施方式的馬桶座裝置的第1步驟下的動作的剖面圖。
圖9(b)是圖9(a)所示的區域R4的放大圖。
虛線箭頭表示由送風裝置513形成的氣流。如圖9(a)所示，在第1步驟中，送風裝置513朝向前方且下方送風。從送風裝置513送出的空氣的至少一部分與馬桶800內(盆部801內或者盆緣部805的內壁面807)相碰而朝向上方。藉此，形成從比馬桶座部200靠下方的馬桶800內向馬桶座部200的上方上升的上升氣流U1。9(a) and 9(b) are cross-sectional views illustrating an operation of the toilet seat device of the embodiment in the first step.
Fig. 9(b) is an enlarged view of a region R4 shown in Fig. 9(a).
The dotted arrow indicates the air flow formed by the air blowing device 513. As shown in FIG. 9(a), in the first step, the air blowing device 513 blows air toward the front and the lower side. At least a part of the air sent from the air blowing device 513 faces the inside of the toilet 800 (in the bowl portion 801 or the inner wall surface 807 of the bowl portion 805) and faces upward. Thereby, the ascending airflow U1 rising from the inside of the toilet bowl 800 below the toilet seat part 200 to the upper side of the toilet seat part 200 is formed.

實線箭頭表示從噴霧裝置481噴出的水霧的流動。實線箭頭的粗細與除菌水的量對應。箭頭越粗表示除菌水越多。在第1步驟中，一部分水霧從噴霧裝置481朝向盆緣部的內壁面807放射出去。粒徑比較小的水霧藉由上升氣流向盆緣部的上表面806、馬桶座部200以及馬桶蓋300等著水。粒徑比較大的水霧也可以向盆部801、盆緣部805的內壁面807著水。The solid arrows indicate the flow of the water mist ejected from the spray device 481. The thickness of the solid arrow corresponds to the amount of the sterilizing water. The thicker the arrow, the more the sterilizing water is. In the first step, a part of the water mist is radiated from the spray device 481 toward the inner wall surface 807 of the bowl edge portion. The water mist having a relatively small particle diameter is watered by the upward airflow to the upper surface 806 of the bowl edge portion, the toilet seat portion 200, and the toilet lid 300. The water mist having a relatively large particle diameter may also be watered on the inner wall surface 807 of the bowl portion 801 and the bowl edge portion 805.

另外，在實施方式中，在噴嘴473的寬度方向(短邊方向)上，在噴霧裝置481與送風裝置513之間配置有噴嘴473(參照圖4)。即，噴霧裝置481在左右方向上配置於從送風裝置513離開的位置。藉此，能夠抑制小粒徑的第1水霧M1在搭乘第1上升氣流U1之前搭乘從送風裝置513朝向馬桶800內送風而成的氣流(產生第1上升氣流U1之前的氣流)而向馬桶800內著水。Further, in the embodiment, a nozzle 473 (see FIG. 4) is disposed between the spray device 481 and the air blowing device 513 in the width direction (short side direction) of the nozzle 473. That is, the spray device 481 is disposed at a position separated from the air blowing device 513 in the left-right direction. In this way, it is possible to prevent the first water mist M1 having a small particle diameter from riding on the airflow from the air blowing device 513 toward the toilet 800 before the first ascending airflow U1 is taken (the airflow before the first ascending airflow U1 is generated) to the toilet. 800 inside the water.

圖10(a)～圖10(d)是例示出實施方式的馬桶座裝置的第1步驟下的動作的俯視圖。
在圖10(a)以及圖10(c)中，為了便於說明，省略了馬桶座部200以及馬桶蓋300。虛線箭頭表示送風裝置513的送風方向。實線箭頭表示從噴霧裝置481噴出的水霧的流動。實線箭頭的粗細與除菌水的量對應。箭頭越粗表示除菌水越多。圖10(b)以及圖10(d)表示馬桶座部200。
圖10(a)以及圖10(b)表示噴霧裝置481的盤481b在俯視觀察的情況下呈逆時針旋轉時的樣子。在這種情況下，沖廁裝置10的左側比右側著水更多的除菌水。例如，如圖10(a)所示，在盆緣部上表面，左側區域RL1比右側區域RR1著水更多的除菌水。例如，如圖10(b)所示，在馬桶座部200，左側區域RL2比右側區域RR2著水更多的除菌水。FIGS. 10( a ) to 10 ( d ) are plan views illustrating an operation of the toilet seat device according to the embodiment in the first step.
In FIGS. 10(a) and 10(c), the toilet seat portion 200 and the toilet lid 300 are omitted for convenience of explanation. The dotted arrow indicates the blowing direction of the air blowing device 513. The solid arrows indicate the flow of the water mist ejected from the spray device 481. The thickness of the solid arrow corresponds to the amount of the sterilizing water. The thicker the arrow, the more the sterilizing water is. 10(b) and 10(d) show the toilet seat portion 200.
FIGS. 10(a) and 10(b) show how the disk 481b of the spray device 481 rotates counterclockwise in a plan view. In this case, the left side of the flushing device 10 has more sterilizing water than the water on the right side. For example, as shown in FIG. 10(a), on the upper surface of the bowl edge portion, the left side region RL1 is more water-removed than the right side region RR1. For example, as shown in FIG. 10(b), in the toilet seat portion 200, the left side region RL2 is more water-repellent than the right side region RR2.

圖10(c)以及圖10(d)表示噴霧裝置481的盤481b在俯視觀察的情況下呈順時針旋轉時的樣子。在這種情況下，沖廁裝置10的右側比左側著水更多的除菌水。例如，如圖10(c)所示，在盆緣部上表面，右側區域RR1比左側區域RL1著水更多的除菌水。例如，如圖10(d)所示，在馬桶座部200，右側區域RR2比左側區域RL2著水更多的除菌水。FIGS. 10(c) and 10(d) show how the disk 481b of the spray device 481 rotates clockwise in a plan view. In this case, the right side of the flushing device 10 has more sterilizing water than the left side. For example, as shown in FIG. 10(c), on the upper surface of the bowl edge portion, the right side region RR1 is more water-removed than the left side region RL1. For example, as shown in FIG. 10(d), in the toilet seat portion 200, the right side region RR2 is more water-removed than the left side region RL2.

控制裝置405較佳為控制噴霧裝置481的馬達481a而在第1步驟中適當地切換順時針旋轉和逆時針旋轉。藉此，容易使左右方向上的水霧的分佈變得均勻。The control device 405 preferably controls the motor 481a of the spray device 481 to appropriately switch the clockwise rotation and the counterclockwise rotation in the first step. Thereby, it is easy to make the distribution of the water mist in the left-right direction uniform.

圖11(a)～圖11(c)是例示出實施方式的馬桶座裝置的第2步驟中的動作的剖面圖以及俯視圖。
實線箭頭表示從噴霧裝置481噴出的水霧的流動。實線箭頭的粗細與除菌水的量對應。箭頭越粗表示除菌水越多。此外，為了便於說明，在圖11(a)中省略了馬桶蓋300，在圖11(b)以及圖11(c)中省略了馬桶座部200以及馬桶蓋300。另外，在該例中，在第2步驟中，控制裝置405不使送風裝置513工作。即，在第2步驟中，不執行朝向馬桶800內的送風。11(a) to 11(c) are a cross-sectional view and a plan view illustrating an operation in a second step of the toilet seat device according to the embodiment.
The solid arrows indicate the flow of the water mist ejected from the spray device 481. The thickness of the solid arrow corresponds to the amount of the sterilizing water. The thicker the arrow, the more the sterilizing water is. Further, for convenience of explanation, the toilet lid 300 is omitted in FIG. 11(a), and the toilet seat portion 200 and the toilet lid 300 are omitted in FIGS. 11(b) and 11(c). Further, in this example, in the second step, the control device 405 does not operate the air blowing device 513. That is, in the second step, the air blowing toward the inside of the toilet 800 is not performed.

如圖11(a)的剖面圖所示，噴霧裝置481朝向盆緣部805的上端噴出水霧。在第2步驟中，除菌水的水霧向盆部801以及盆緣部805的內壁面807著水。由於在第2步驟中不產生第1上升氣流U1，所以除菌水的水霧例如不向馬桶座部200、盆緣部805的上表面806著水。As shown in the cross-sectional view of Fig. 11(a), the spray device 481 sprays water mist toward the upper end of the bowl edge portion 805. In the second step, the water mist of the sterilizing water converges on the inner wall surface 807 of the bowl portion 801 and the bowl edge portion 805. Since the first ascending airflow U1 is not generated in the second step, the water mist of the sterilization water does not, for example, water on the upper surface 806 of the toilet seat portion 200 or the bowl edge portion 805.

圖11(b)的俯視圖表示噴霧裝置481的盤481b在俯視觀察的情況下呈逆時針旋轉時的樣子。在這種情況下，馬桶800內的左側比右側著水更多的除菌水。Fig. 11(b) is a plan view showing a state in which the disk 481b of the spray device 481 is rotated counterclockwise in a plan view. In this case, the left side of the toilet 800 has more sterilizing water than the water on the right side.

圖11(c)的俯視圖表示噴霧裝置481的盤481b在俯視觀察的情況下呈順時針旋轉時的樣子。在這種情況下，馬桶800內的右側比左側著水更多的除菌水。The plan view of Fig. 11(c) shows a state in which the disk 481b of the spray device 481 is rotated clockwise in a plan view. In this case, the right side of the toilet 800 has more sterilizing water than the left side.

控制裝置405較佳為對噴霧裝置481的馬達481a進行控制而在第2步驟中適當地切換順時針旋轉和逆時針旋轉。藉此，容易使左右方向上的水霧的分佈變得均勻。The control device 405 preferably controls the motor 481a of the spray device 481 to appropriately switch the clockwise rotation and the counterclockwise rotation in the second step. Thereby, it is easy to make the distribution of the water mist in the left-right direction uniform.

如以上說明般，藉由第1步驟，能夠使除菌水著水於盆緣部805的上表面806、馬桶座部200以及馬桶蓋300等。另外，藉由第2步驟，能夠使除菌水著於水盆部801以及盆緣部805的內壁面807。藉由以上的過程，能夠對包含盆緣部805、馬桶座部200以及馬桶蓋300等在內的沖廁裝置10的各個角落進行除菌。As described above, in the first step, the sterilization water can be caused to flow on the upper surface 806 of the bowl edge portion 805, the toilet seat portion 200, the toilet lid 300, and the like. Further, in the second step, the sterilizing water can be placed on the inner wall surface 807 of the bowl portion 801 and the bowl portion 805. By the above process, each corner of the toilet device 10 including the bowl edge portion 805, the toilet seat portion 200, the toilet lid 300, and the like can be sterilized.

圖12是例示出實施方式的馬桶座裝置的便後噴霧模式下的動作的流程圖。
若人體感測器403檢測到使用者離開(步驟S401：Yes)，則控制裝置405控制馬桶蓋用馬達512而關閉馬桶蓋300，並打開電磁閥431，使噴霧裝置481的馬達481a以及盤481b逆時針(CCW)高速旋轉(步驟S402)。藉由電磁閥431的打開，朝向盤481b的供水開始。Fig. 12 is a flowchart illustrating an operation in the post-spray mode of the toilet seat device of the embodiment.
If the human body sensor 403 detects that the user has left (step S401: Yes), the control device 405 controls the toilet lid motor 512 to close the toilet lid 300, and opens the solenoid valve 431 to make the motor 481a and the disk 481b of the spray device 481. Counterclockwise (CCW) rotation at high speed (step S402). The water supply to the disk 481b is started by the opening of the solenoid valve 431.

控制裝置405將盤481b高速旋轉的狀態維持預定時間(步驟S403：No)。藉此，能夠將盤481b上的殘留水從盤481b上排出。此時，例如水霧擋板482被關閉，因此不向馬桶800內噴出水霧。The control device 405 maintains the state in which the disk 481b is rotated at a high speed for a predetermined time (step S403: No). Thereby, the residual water on the disk 481b can be discharged from the disk 481b. At this time, for example, the water mist baffle 482 is closed, so that no water mist is sprayed into the toilet 800.

若經過預定時間(步驟S403：Yes)，則控制裝置405藉由噴嘴馬達476使噴嘴473進入盆部801內。伴隨於此，水霧擋板482被打開(步驟S404)。When the predetermined time elapses (step S403: Yes), the control device 405 causes the nozzle 473 to enter the bowl portion 801 by the nozzle motor 476. Along with this, the water mist baffle 482 is opened (step S404).

之後，控制裝置405控制除菌裝置450而開始進行除菌水的生成，並且控制送風裝置513而開始進行朝向馬桶800內的送風(步驟S405)。藉此，開始朝向馬桶800內、馬桶座部200以及馬桶蓋300等噴出除菌水的水霧。控制裝置405將從逆時針高速旋轉的盤481b噴出除菌水的水霧的狀態維持預定時間(t1)(步驟S406：No)。Thereafter, the control device 405 controls the sterilization device 450 to start the generation of the sterilization water, and controls the air blowing device 513 to start the air blowing toward the toilet 800 (step S405). Thereby, the water mist which sprays the sterilizing water is started toward the toilet 800, the toilet seat part 200, the toilet seat 300, etc.. The control device 405 maintains the state in which the water mist of the sterilizing water is ejected from the disk 481b rotating at a high speed counterclockwise for a predetermined time (t1) (step S406: No).

若經過預定時間(t1)(步驟S406：Yes)，則控制裝置405使噴霧裝置481的馬達481a以及盤481b順時針(CW)高速旋轉(步驟S407)。控制裝置405將從順時針高速旋轉的盤481b噴出除菌水的水霧的狀態維持預定時間(t1)(步驟S408：No)。例如，步驟S405~步驟S408相當於第1步驟。When the predetermined time (t1) has elapsed (step S406: Yes), the control device 405 causes the motor 481a and the disk 481b of the spray device 481 to rotate at a high speed clockwise (CW) (step S407). The control device 405 maintains the state in which the mist of the sterilizing water is ejected from the disk 481b rotating at a high speed clockwise for a predetermined time (t1) (step S408: No). For example, steps S405 to S408 correspond to the first step.

若經過預定時間(t1)(步驟S408：Yes)，則控制裝置405控制送風裝置513而停止送風，並使馬達481a以及盤481b順時針(CW)中速旋轉(步驟S409)。藉此，抑制水霧朝向馬桶座部200、盆緣部的上表面806的著水，並向盆部801以及盆緣部的內壁面807噴出水霧。控制裝置405將從順時針中速旋轉的盤481b噴出除菌水的水霧的狀態維持預定時間(t2)(步驟S410：No)。When the predetermined time (t1) has elapsed (step S408: Yes), the control device 405 controls the air blowing device 513 to stop the air blowing, and rotates the motor 481a and the disk 481b clockwise (CW) at a medium speed (step S409). Thereby, the water mist is prevented from flowing toward the upper surface 806 of the toilet seat portion 200 and the bowl edge portion, and the water mist is discharged to the bowl portion 801 and the inner wall surface 807 of the bowl edge portion. The control device 405 maintains the state in which the mist of the sterilizing water is ejected from the disk 481b rotated clockwise at the medium speed for a predetermined time (t2) (step S410: No).

若經過預定時間(t2)(步驟S410：Yes)，則控制裝置405使噴霧裝置481的馬達481a以及盤481b逆時針(CCW)中速旋轉(步驟S411)。控制裝置405將從逆時針中速旋轉的盤481b噴出除菌水的水霧的狀態維持預定時間(t2)(步驟S412：No)。例如，步驟S409～步驟S412相當於第2步驟。When the predetermined time (t2) has elapsed (step S410: Yes), the control device 405 causes the motor 481a of the spray device 481 and the disk 481b to rotate counterclockwise (CCW) at a medium speed (step S411). The control device 405 maintains the state in which the mist of the sterilizing water is ejected from the disk 481b that rotates counterclockwise at the medium speed for a predetermined time (t2) (step S412: No). For example, steps S409 to S412 correspond to the second step.

若經過預定時間(t2)(步驟S412：Yes)，則控制裝置405控制除菌裝置450而停止除菌水的生成(步驟S413)。When the predetermined time (t2) has elapsed (step S412: Yes), the control device 405 controls the sterilization device 450 to stop the generation of the sterilization water (step S413).

控制裝置405將向盤481b供給自來水且使盤481b中速旋轉的狀態維持預定時間(步驟S414：No)。藉此，進行盤481b的自我清潔。其中，自我清潔是指以並不產生水霧的程度的轉速對盤進行物理清洗的動作。自我清潔也可以使用除菌水。The control device 405 maintains the state in which the tap water is supplied to the disk 481b and the disk 481b is rotated at a medium speed for a predetermined time (step S414: No). Thereby, self-cleaning of the disk 481b is performed. Here, self-cleaning refers to an operation of physically cleaning the disk at a rotational speed that does not cause water mist. It is also possible to use sterile water for self-cleaning.

若經過預定時間(步驟S414：Yes)，則控制裝置405關閉電磁閥431(步驟S415)。控制裝置405將停止朝向盤481b的供水且使盤481b以中速旋轉的狀態維持預定時間(步驟S416：No)。藉此，能夠除去盤481b上的殘留水。When the predetermined time has elapsed (step S414: Yes), the control device 405 turns off the solenoid valve 431 (step S415). The control device 405 will stop the water supply to the disk 481b and maintain the disk 481b at a medium speed for a predetermined time (step S416: No). Thereby, the residual water on the disk 481b can be removed.

若經過預定時間(步驟S416：Yes)，則控制裝置405停止馬達481a以及盤481b的旋轉，利用噴嘴馬達476使噴嘴473向外殼400內後退。伴隨於此，水霧擋板482被關閉。另外，控制裝置405將馬桶座加熱器515接通(通電狀態)(步驟S417)。When the predetermined time has elapsed (step S416: Yes), the control device 405 stops the rotation of the motor 481a and the disk 481b, and the nozzle motor 476 retracts the nozzle 473 into the casing 400. Along with this, the water mist baffle 482 is closed. Further, the control device 405 turns on the toilet seat heater 515 (energized state) (step S417).

控制裝置405將馬桶座加熱器515接通的狀態維持預定時間(步驟S418：No)。藉此，使馬桶座部200的溫度上升，使著水於馬桶座部200的除菌水蒸發，從而能夠使馬桶座部200變乾。此外，也可以對送風裝置513和暖風加熱器514進行驅動，而利用暖風來乾燥馬桶座部200，以此代替馬桶座加熱器515。The control device 405 maintains the state in which the toilet seat heater 515 is turned on for a predetermined time (step S418: No). Thereby, the temperature of the toilet seat portion 200 is raised, and the water of the toilet seat 200 is evaporated, so that the toilet seat portion 200 can be dried. Further, the air blowing device 513 and the warm air heater 514 may be driven, and the toilet seat portion 200 may be dried by warm air instead of the toilet seat heater 515.

若經過預定時間(步驟S418：Yes)，則控制裝置405將馬桶座加熱器515斷開(非通電狀態)(步驟S419)。藉由以上過程，結束便後噴霧模式。When the predetermined time has elapsed (step S418: Yes), the control device 405 turns off the toilet seat heater 515 (non-energized state) (step S419). By the above process, the post-and-after spray mode is ended.

如此，控制裝置405在一次噴霧模式中，在執行使除菌水的水霧著水於馬桶座部200、盆緣部805的上表面806的第1步驟後，執行第2步驟。藉此，能夠在第2步驟的執行中使馬桶座部200、盆緣部805的上表面806變乾，從而能夠縮短從一次噴霧模式結束到馬桶座部200、盆緣部805的上表面806變乾為止的時間。In this manner, the control device 405 performs the second step after performing the first step of causing the water mist of the sterilization water to immerse in the upper surface 806 of the toilet seat portion 200 and the bowl edge portion 805 in the one-time spray mode. Thereby, the upper surface 806 of the toilet seat portion 200 and the bowl edge portion 805 can be dried during the execution of the second step, and the upper surface 806 from the end of the primary spray mode to the toilet seat portion 200 and the bowl edge portion 805 can be shortened. The time until it dries.

圖13是例示出實施方式的馬桶座裝置的手動噴霧模式下的動作的流程圖。
若使用者對手動操作部500進行操作(步驟S501：Yes)，則控制裝置405控制馬桶蓋用馬達512而關閉馬桶蓋300，並打開電磁閥431，而使噴霧裝置481的馬達481a以及盤481b逆時針(CCW)高速旋轉(步驟S502)。藉由電磁閥431的打開，朝向盤481b的供水開始。Fig. 13 is a flowchart illustrating an operation in the manual spray mode of the toilet seat device of the embodiment.
When the user operates the manual operation unit 500 (step S501: Yes), the control device 405 controls the toilet lid motor 512 to close the toilet lid 300, and opens the electromagnetic valve 431 to make the motor 481a and the disk 481b of the spray device 481. Counterclockwise (CCW) rotation at high speed (step S502). The water supply to the disk 481b is started by the opening of the solenoid valve 431.

控制裝置405將盤481b高速旋轉的狀態維持預定時間(步驟S503：No)。藉此，能夠將盤481b上的殘留水從盤481b排出。此時，例如水霧擋板482被關閉，因此不向馬桶800內噴出水霧。The control device 405 maintains the state in which the disk 481b is rotated at a high speed for a predetermined time (step S503: No). Thereby, the residual water on the disk 481b can be discharged from the disk 481b. At this time, for example, the water mist baffle 482 is closed, so that no water mist is sprayed into the toilet 800.

若經過預定時間(步驟S503：Yes)，則控制裝置405藉由噴嘴馬達476使噴嘴473進入盆部801內。伴隨於此，水霧擋板482被打開(步驟S504)。When the predetermined time elapses (step S503: Yes), the control device 405 causes the nozzle 473 to enter the bowl portion 801 by the nozzle motor 476. Along with this, the water mist baffle 482 is opened (step S504).

其後，控制裝置405控制除菌裝置450而開始除菌水的生成，並且控制送風裝置513而開始朝向馬桶800內的送風(步驟S505)。藉此，開始朝向馬桶800內、馬桶座部200以及馬桶蓋300等噴出除菌水的水霧。控制裝置405將從逆時針高速旋轉的盤481b噴出除菌水的水霧的狀態維持預定時間(t3)(步驟S506：No)。Thereafter, the control device 405 controls the sterilization device 450 to start the generation of the sterilizing water, and controls the air blowing device 513 to start the air blowing toward the toilet 800 (step S505). Thereby, the water mist which sprays the sterilizing water is started toward the toilet 800, the toilet seat part 200, the toilet seat 300, etc.. The control device 405 maintains the state in which the mist of the sterilizing water is ejected from the disk 481b rotating at a high speed counterclockwise for a predetermined time (t3) (step S506: No).

若經過預定時間(t2)(步驟S506：Yes)，則控制裝置405使噴霧裝置481的馬達481a以及盤481b順時針(CW)高速旋轉(步驟S507)。控制裝置405將從順時針高速旋轉的盤481b噴出除菌水的水霧的狀態維持預定時間(t3)(步驟S508：No)。例如，步驟S505~步驟S508相當於第1步驟。When the predetermined time (t2) has elapsed (step S506: Yes), the control device 405 causes the motor 481a and the disk 481b of the spray device 481 to rotate at a high speed clockwise (CW) (step S507). The control device 405 maintains the state in which the mist of the sterilizing water is ejected from the disk 481b that rotates clockwise at a high speed for a predetermined time (t3) (step S508: No). For example, steps S505 to S508 correspond to the first step.

若經過預定時間(t3)(步驟S508：Yes)，則控制裝置405控制送風裝置513而停止送風，並使馬達481a以及盤481b順時針(CW)中速旋轉(步驟S509)。藉此，抑制水霧朝向馬桶座部200、盆緣部的上表面806的著水，並朝向盆部801以及盆緣部的內壁面807噴出水霧。控制裝置405將從順時針中速旋轉的盤481b噴出除菌水的水霧的狀態維持預定時間(t4)(步驟S510：No)。When the predetermined time (t3) has elapsed (step S508: Yes), the control device 405 controls the air blowing device 513 to stop the air blowing, and rotates the motor 481a and the disk 481b clockwise (CW) at a medium speed (step S509). Thereby, the water mist is prevented from flowing toward the toilet seat portion 200 and the upper surface 806 of the bowl edge portion, and the water mist is sprayed toward the bowl portion 801 and the inner wall surface 807 of the bowl edge portion. The control device 405 maintains the state in which the mist of the sterilizing water is ejected from the disk 481b that rotates clockwise at a medium speed for a predetermined time (t4) (step S510: No).

若經過預定時間(t4)(步驟S510：Yes)，則控制裝置405使噴霧裝置481的馬達481a以及盤481b逆時針(CCW)中速旋轉(步驟S511)。控制裝置405將從逆時針中速旋轉的盤481b噴出除菌水的水霧的狀態維持預定時間(t4)(步驟S512：No)。例如，步驟S509～步驟S512相當於第2步驟。When the predetermined time (t4) has elapsed (step S510: Yes), the control device 405 causes the motor 481a of the spray device 481 and the disk 481b to rotate counterclockwise (CCW) at a medium speed (step S511). The control device 405 maintains the state in which the mist of the sterilizing water is ejected from the disk 481b that rotates counterclockwise at the medium speed for a predetermined time (t4) (step S512: No). For example, steps S509 to S512 correspond to the second step.

若經過預定時間(t4)(步驟S512：Yes)，則控制裝置405控制除菌裝置450而停止除菌水的生成(步驟S513)。When the predetermined time (t4) has elapsed (step S512: Yes), the control device 405 controls the sterilization device 450 to stop the generation of the sterilization water (step S513).

控制裝置405將朝向盤481b供給自來水且使盤481b中速旋轉的狀態維持預定時間(步驟S514：No)。藉此，進行盤481b的自我清潔。The control device 405 maintains the state in which the tap water is supplied to the disk 481b and the disk 481b is rotated at a medium speed for a predetermined time (step S514: No). Thereby, self-cleaning of the disk 481b is performed.

若經過預定時間(步驟S514：Yes)，則控制裝置405關閉電磁閥431(步驟S515)。控制裝置405將停止朝向盤481b的供水且使盤481b以中速旋轉的狀態維持預定時間(步驟S516：No)。藉此，能夠除去盤481b上的殘留水。When the predetermined time has elapsed (step S514: Yes), the control device 405 turns off the solenoid valve 431 (step S515). The control device 405 will stop the water supply to the disk 481b and maintain the disk 481b at a medium speed for a predetermined time (step S516: No). Thereby, the residual water on the disk 481b can be removed.

若經過預定時間(步驟S516：Yes)，則控制裝置405停止馬達481a以及盤481b的旋轉，利用噴嘴馬達476使噴嘴473向外殼400內後退。伴隨於此，水霧擋板482被關閉(步驟S517)。藉由以上過程，結束手動噴霧模式。另外，使用者在手動噴霧模式後，藉由用衛生紙等將著水於馬桶座部200的除菌水適當地擦掉，從而能夠對馬桶座部200進行除菌。When the predetermined time has elapsed (step S516: Yes), the control device 405 stops the rotation of the motor 481a and the disk 481b, and the nozzle motor 476 retracts the nozzle 473 into the casing 400. Along with this, the water mist baffle 482 is closed (step S517). With the above process, the manual spray mode is ended. Further, after the user manually wipes the sterilizing water that has been immersed in the toilet seat portion 200 with a toilet paper or the like in the manual spray mode, the toilet seat portion 200 can be sterilized.

控制裝置405在手動噴霧模式以及便後噴霧模式中，使執行第1步驟的時間比執行第2步驟的時間短。例如，在參照圖12說明的便後噴霧模式中，預定時間(t1)比預定時間(t2)短。另外，在參照圖13說明的手動噴霧模式中，預定時間(t3)比預定時間(t4)短。藉由縮短第1步驟的時間，能夠更確實地減少著水於馬桶座部200以及盆緣部805的上表面806的除菌水的量。另一方面，藉由加長第2步驟的時間，能夠增大著水於盆部801以及盆緣部805的內壁面807的除菌水的量。The control device 405 makes the time for executing the first step shorter than the time for executing the second step in the manual spray mode and the post-spray spray mode. For example, in the post-spray spray mode explained with reference to Fig. 12, the predetermined time (t1) is shorter than the predetermined time (t2). Further, in the manual spray mode explained with reference to Fig. 13, the predetermined time (t3) is shorter than the predetermined time (t4). By shortening the time of the first step, the amount of the sterilizing water that is immersed in the upper surface 806 of the toilet seat portion 200 and the bowl edge portion 805 can be more reliably reduced. On the other hand, by lengthening the time of the second step, the amount of the sterilizing water in the inner wall surface 807 of the bowl portion 801 and the bowl portion 805 can be increased.

此外，控制裝置405對噴霧裝置進行控制，以使得手動噴霧模式中噴出除菌水的時間比便後噴霧模式中噴出除菌水的時間長。例如，參照圖13說明的預定時間(t3)比參照圖12說明的預定時間(t1)長。藉此，能夠使手動噴霧模式中著水於馬桶座部200的除菌水的量比便後噴霧模式中著水於馬桶座部200的除菌水的量多。藉此，在手動噴霧模式中使除菌水充分地浸透衛生紙等，從而能夠提高除菌性能。另外，能夠防止在擦拭時樹脂制的馬桶座部200受到損傷。Further, the control device 405 controls the spray device such that the time for spraying the sterilizing water in the manual spray mode is longer than the time during which the sterilizing water is sprayed in the post-spray mode. For example, the predetermined time (t3) explained with reference to FIG. 13 is longer than the predetermined time (t1) explained with reference to FIG. Thereby, the amount of the sterilizing water that is immersed in the toilet seat portion 200 in the manual spray mode can be made larger than the amount of the sterilizing water that is immersed in the toilet seat portion 200 in the post-spraying mode. Thereby, the sterilization water can be sufficiently impregnated into the toilet paper or the like in the manual spray mode, whereby the sterilization performance can be improved. In addition, it is possible to prevent the resin seat portion 200 made of resin from being damaged during wiping.

例如，也可以想到不改變噴出除菌水的時間而是改變除菌水的水霧的粒徑來改變除菌水的著水量的方法。例如，藉由增大粒徑，能夠增多除菌水的著水量。但是，若增大粒徑，則存在除菌水難以搭乘上升氣流之虞。針對於此，藉由改變噴出除菌水的時間，能夠不改變粒徑就增多著水於馬桶座部200等的除菌水的量。因此，能夠使除菌水的水霧容易搭乘上升氣流，能夠使除菌水向馬桶座部200等的大片範圍擴散。For example, it is also conceivable to change the amount of water of the sterilizing water by changing the particle size of the water mist of the sterilizing water without changing the time for discharging the sterilizing water. For example, by increasing the particle size, the amount of water of the sterilizing water can be increased. However, if the particle diameter is increased, it is difficult for the sterilizing water to ride on the upward flow. On the other hand, by changing the time during which the sterilizing water is sprayed, the amount of the sterilizing water that is immersed in the toilet seat portion 200 or the like can be increased without changing the particle diameter. Therefore, the mist of the sterilizing water can be easily taken up by the ascending airflow, and the sterilizing water can be diffused to a large extent of the toilet seat 200 or the like.

另外，控制裝置405在便後噴霧模式的執行中或者執行後，使對馬桶座部200進行乾燥的乾燥裝置以第1乾燥力工作。例如，在圖12中，控制裝置405在步驟S417、S418中使馬桶座加熱器515以第1加熱量(第1電力(瓦))工作。
另一方面，控制裝置405在手動噴霧模式的執行中或者執行後，不使乾燥裝置工作、或者使其以比第1乾燥力小的第2乾燥力工作。例如，在圖13中，控制裝置405不使馬桶座加熱器515工作。或者，控制裝置405也可以使馬桶座加熱器515以比第1加熱量小的第2加熱量(第2電力(瓦))工作。例如，利用馬桶座加熱器515，使便後噴霧模式的執行中或者執行後的座面的溫度，比手動噴霧模式的執行中或者執行後的座面的溫度高。Further, the control device 405 operates the drying device that dries the toilet seat portion 200 with the first drying force during or after the execution of the post-spraying mode. For example, in FIG. 12, the control device 405 operates the toilet seat heater 515 at the first heating amount (first electric power (watt)) in steps S417 and S418.
On the other hand, the control device 405 does not operate the drying device or operates at a second drying force smaller than the first drying force during or after execution of the manual spray mode. For example, in Figure 13, control device 405 does not operate toilet seat heater 515. Alternatively, the control device 405 may operate the toilet seat heater 515 with a second heating amount (second electric power (watt)) that is smaller than the first heating amount. For example, with the toilet seat heater 515, the temperature of the seat surface during or after the execution of the post-spray spray mode is higher than the temperature of the seat surface during or after the execution of the manual spray mode.

如此，在便後噴霧模式的執行中或者執行後，乾燥裝置以比較大的第1乾燥力(例如第1電力)使馬桶座部200變乾，從而能夠縮短著水於馬桶座部200的除菌水的乾燥時間。另一方面，在手動噴霧模式的執行中或者執行後，乾燥裝置不工作、或者以比較小的第2乾燥力(例如第2電力)使馬桶座部200變乾，從而能夠增長著水於馬桶座部200的除菌水的乾燥時間。藉此，能夠防止在用衛生紙將著水於馬桶座部200的除菌水擦掉前，馬桶座部200變乾。In this manner, during or after the execution of the post-spraying mode, the drying device dries the toilet seat portion 200 with a relatively large first drying force (for example, the first electric power), thereby shortening the drainage of the toilet seat portion 200. The drying time of the bacteria water. On the other hand, during or after the execution of the manual spray mode, the drying device does not operate, or the toilet seat portion 200 is dried with a relatively small second drying force (for example, the second electric power), so that the toilet can be grown on the toilet. The drying time of the sterilization water of the seat 200. Thereby, it is possible to prevent the toilet seat portion 200 from drying out before the sterilizing water that has been immersed in the toilet seat portion 200 with the toilet paper is wiped off.

參照圖14～圖16對便前噴霧模式下的馬桶座裝置100的動作的例子進行說明。
圖14是例示出實施方式的馬桶座裝置的便前噴霧模式下的動作的示意圖。
在便前噴霧模式中，控制裝置405使噴霧裝置481工作，產生水霧M3(除菌水的水霧或者自來水的水霧)。另外，控制裝置405以在使噴霧裝置481噴出水霧M3的狀態下不產生第1上升氣流U1而不使水霧M3向馬桶座部200側上升的方式控制送風裝置513。其中，第1上升氣流U1如上前述為由送風裝置513製造的氣流，並且是能夠在便後噴霧模式以及手動噴霧模式中使除菌水的水霧向馬桶座部200側上升的氣流。An example of the operation of the toilet seat apparatus 100 in the pre-spray mode will be described with reference to Figs. 14 to 16 .
Fig. 14 is a schematic view exemplifying an operation of the toilet seat device of the embodiment in the pre-spray mode.
In the pre-dash spray mode, the control device 405 operates the spray device 481 to generate a water mist M3 (water mist of the sterilizing water or water mist of the tap water). In addition, the control device 405 controls the air blowing device 513 so that the first ascending airflow U1 does not occur in a state where the water mist M3 is ejected by the spray device 481, and the water mist M3 is not raised toward the toilet seat portion 200 side. In the above-described first ascending airflow U1, as described above, the airflow is generated by the air blowing device 513, and the airflow in which the mist of the sterilizing water is raised toward the toilet seat 200 side in the post-spray mode and the manual spray mode.

在便前噴霧模式中，從比馬桶座部200靠下方的部位噴出的水霧不向馬桶座部200側上升，而是向馬桶800的盆部801、盆緣部805的內壁面807著水。在盆部801、內壁面807形成水膜，從而難以附著污垢。另外，由於水霧不向馬桶座部200側上升，所以能夠在便前噴霧模式中抑制馬桶座部200以及盆緣部805的上表面806被潤濕。藉此，在便前噴霧模式之後使用者立即就座、或者用手轉動馬桶座部200的情況下，能夠防止使用者的手、臀部被潤濕。
另一方面，在便後噴霧模式以及手動噴霧模式中，控制裝置405使送風裝置513工作，利用第1上升氣流U1使除菌水的水霧向馬桶座部200側上升。In the pre-dash spray mode, the water mist ejected from the portion below the toilet seat portion 200 does not rise toward the toilet seat portion 200 side, but is flushed toward the bowl portion 801 of the toilet bowl 800 and the inner wall surface 807 of the bowl edge portion 805. . A water film is formed on the bowl portion 801 and the inner wall surface 807, so that it is difficult to adhere to dirt. Further, since the water mist does not rise toward the toilet seat portion 200 side, the upper surface 806 of the toilet seat portion 200 and the bowl edge portion 805 can be suppressed from being wetted in the pre-spraying mode. Thereby, when the user immediately sits on the toilet seat or rotates the toilet seat 200 by hand, the user's hands and buttocks can be prevented from being wetted.
On the other hand, in the post-spray mode and the manual spray mode, the control device 405 operates the air blowing device 513 to raise the water mist of the sterilization water toward the toilet seat portion 200 by the first ascending airflow U1.

即，控制裝置405能夠切換：使從比馬桶座部200靠下方的部位噴出的水霧搭乘上升氣流而向馬桶座部200著水的情況、與不使水霧搭乘上升氣流的情況。藉此，能夠利用單一的噴霧裝置481，在便後噴霧模式以及手動噴霧模式中使除菌水的水霧向馬桶800內以及馬桶座部200著水，而在便前噴霧模式中以不潤濕馬桶座部200的方式使水霧向馬桶800內著水。In other words, the control device 405 can switch between the case where the water mist ejected from the portion below the toilet seat portion 200 rides the ascending air current to the toilet seat portion 200, and the case where the water mist is not taken up. Thereby, the single spray device 481 can be used to make the water mist of the sterilizing water into the toilet 800 and the toilet seat 200 in the post-dose spray mode and the manual spray mode, and the wet spray mode does not run in the spray mode. The manner in which the toilet seat 200 is wet places the water mist into the toilet 800.

此外，在便前噴霧模式中“不使除菌水的水霧或者自來水的水霧向馬桶座部側上升”的範圍，不僅包括全部的水霧均不上升的情況，還可以包括微量的水霧上升的情況。例如，便前噴霧模式中向馬桶座部側上升的水霧的量，比便後噴霧模式或者手動噴霧模式中向馬桶座部側上升的水霧的量少。In addition, in the pre-spraying mode, the range of "the water mist of the sterilizing water or the water mist of the tap water is raised toward the toilet seat side" includes not only the case where all the water mist does not rise, but also a trace amount of water. The situation of fog rising. For example, the amount of water mist rising toward the toilet seat side in the front spray mode is smaller than the amount of water mist rising toward the toilet seat side in the post-spray mode or the manual spray mode.

例如，在便前噴霧模式中，控制裝置405使送風裝置513的工作停止，而不進行送風。藉此，能夠更確實地防止水霧向馬桶座部200側上升。For example, in the pre-dash mode, the control device 405 stops the operation of the air blowing device 513 without performing air blowing. Thereby, it is possible to more reliably prevent the water mist from rising toward the toilet seat portion 200 side.

另外，在便前噴霧模式中，控制裝置405也可以使送風裝置513工作而產生上升氣流U3。上升氣流U3的流速比第1上升氣流U1的流速低，水霧M3不因上升氣流U3而向馬桶座部200側上升。能夠利用上升氣流U3使水霧不向馬桶座部200側上升而是向水平方向或者下方擴散。藉此，能夠使除菌水著水於馬桶800內的更大的範圍。Further, in the pre-dash mode, the control device 405 may operate the blower 513 to generate the ascending airflow U3. The flow rate of the updraft U3 is lower than the flow rate of the first updraft U1, and the mist M3 does not rise toward the toilet seat 200 side by the updraft U3. The updraft U3 can be used to diffuse the water mist to the toilet seat 200 side but to the horizontal direction or below. Thereby, the sterilizing water can be made to immerse in a larger range in the toilet 800.

另外，在便前噴霧模式中，噴霧裝置481也使除菌水的水霧或者自來水的水霧在俯視觀察時以放射狀噴霧。藉此，即便在便前噴霧模式中水霧未搭乘上升氣流的情況下，也能夠使水霧著水於盆部801、盆緣部805的內壁面807等的大片範圍。Further, in the pre-spraying mode, the spray device 481 also sprays the mist of the sterilizing water or the mist of the tap water in a plan view. Thereby, even if the water mist does not ride the updraft in the pre-spray mode, the water mist can be immersed in a large range of the basin portion 801, the inner wall surface 807 of the bowl edge portion 805, and the like.

水霧M3例如是中粒徑或者大粒徑的水霧。水霧M3的粒徑(除菌水或者自來水的微粒p3的直徑)例如也可以比手動噴霧模式、便後噴霧模式中的第1水霧M1的粒徑、第2水霧M2的粒徑大。藉此，也可以使水霧M3不向馬桶座部200側上升。The water mist M3 is, for example, a water mist having a medium particle diameter or a large particle diameter. The particle diameter of the water mist M3 (the diameter of the sterilizing water or the fine particles p3 of the tap water) may be larger than the particle diameter of the first water mist M1 and the particle diameter of the second water mist M2 in the manual spray mode or the post-dose spray mode, for example. . Thereby, the water mist M3 can be prevented from rising toward the toilet seat portion 200 side.

圖15(a)～圖15(c)是例示出實施方式的馬桶座裝置的便前噴霧模式下的動作的剖面圖以及俯視圖。
圖15(a)～圖15(c)例示出噴霧裝置481的馬達481a為中速旋轉的狀態。此時，噴霧裝置481所噴出的水霧為中粒徑的水霧。另外，在圖15(a)～圖15(c)中，實線箭頭表示從噴霧裝置481噴出的水霧的流動。實線箭頭的粗細與除菌水的量對應。箭頭越粗表示除菌水越多。此外，在圖15(b)以及圖15(c)中，為了便於說明，省略了馬桶座部200。15(a) to 15(c) are a cross-sectional view and a plan view illustrating an operation of the toilet seat device of the embodiment in the pre-spray mode.
15(a) to 15(c) illustrate a state in which the motor 481a of the spray device 481 is rotated at a medium speed. At this time, the water mist sprayed by the spray device 481 is a water mist having a medium particle diameter. In addition, in FIGS. 15( a ) to 15 ( c ), solid arrows indicate the flow of the water mist sprayed from the spray device 481 . The thickness of the solid arrow corresponds to the amount of the sterilizing water. The thicker the arrow, the more the sterilizing water is. In addition, in FIGS. 15(b) and 15(c), the toilet seat portion 200 is omitted for convenience of explanation.

如圖15(a)的剖面圖所示，噴霧裝置481朝向盆緣部805的上端噴出水霧。在馬達481a為中速旋轉的情況下，馬桶800的外側區域RS(盆部801內的外側部分801S以及盆緣部805的內壁面807)比馬桶800的內側區域RU(盆部801的內側部分801U)著水更多的除菌水或者自來水。As shown in the cross-sectional view of Fig. 15 (a), the spray device 481 sprays water mist toward the upper end of the bowl edge portion 805. When the motor 481a is rotated at a medium speed, the outer region RS of the toilet 800 (the outer portion 801S in the bowl portion 801 and the inner wall surface 807 of the bowl portion 805) is larger than the inner portion RU of the toilet bowl 800 (the inner portion of the bowl portion 801). 801U) More sterilizing water or tap water in the water.

圖15(b)的俯視圖表示噴霧裝置481的盤481b在俯視觀察的情況下呈逆時針旋轉時的樣子。在這種情況下，馬桶800內的左側比右側著水更多的除菌水或者自來水。The plan view of Fig. 15 (b) shows a state in which the disk 481b of the spray device 481 is rotated counterclockwise in a plan view. In this case, the left side of the toilet 800 has more sterilizing water or tap water than the water on the right side.

圖15(c)的俯視圖表示噴霧裝置481的盤481b在俯視觀察的情況下呈順時針旋轉時的樣子。在這種情況下，馬桶800內的右側比左側著水更多的除菌水或者自來水。The top view of Fig. 15 (c) shows a state in which the disk 481b of the spray device 481 is rotated clockwise in a plan view. In this case, the right side of the toilet 800 has more sterilizing water or tap water than the left side.

圖16(a)～圖16(c)是例示出實施方式的馬桶座裝置的便前噴霧模式下的動作的剖面圖以及俯視圖。
圖16(a)～圖16(c)例示出噴霧裝置481的馬達481a為低速旋轉的狀態。此時，噴霧裝置481所噴出的水霧為大粒徑的水霧。另外，在圖16(a)～圖16(c)中，實線箭頭表示從噴霧裝置481噴出的水霧的流動。實線箭頭的粗細與除菌水的量對應。箭頭越粗表示除菌水越多。此外，在圖16(b)以及圖16(c)中，為了便於說明，省略了馬桶座部200。16(a) to 16(c) are a cross-sectional view and a plan view showing an operation of the toilet seat device of the embodiment in the front spray mode.
16(a) to 16(c) illustrate a state in which the motor 481a of the spray device 481 is rotated at a low speed. At this time, the water mist sprayed by the spray device 481 is a water mist having a large particle diameter. In addition, in FIGS. 16( a ) to 16 ( c ), solid arrows indicate the flow of the water mist sprayed from the spray device 481 . The thickness of the solid arrow corresponds to the amount of the sterilizing water. The thicker the arrow, the more the sterilizing water is. In addition, in FIGS. 16(b) and 16(c), the toilet seat portion 200 is omitted for convenience of explanation.

在馬達481a為低速旋轉的情況下，與馬達為中速旋轉的情況相比，水霧的粒徑大，離心力也小，因此水霧的飛行距離變短。如圖16(a)的剖面圖所示，在馬達481a為低速旋轉的情況下，馬桶800的內側區域RU比馬桶800的外側區域RS著水更多的除菌水或者自來水。When the motor 481a is rotated at a low speed, the water mist has a larger particle diameter and a smaller centrifugal force than when the motor is rotated at a medium speed, and thus the flying distance of the water mist is shortened. As shown in the cross-sectional view of Fig. 16(a), when the motor 481a is rotated at a low speed, the inner region RU of the toilet 800 is more water-removed or tap water than the outer region RS of the toilet 800.

圖16(b)的俯視圖表示噴霧裝置481的盤481b在俯視觀察的情況下呈順時針旋轉時的樣子。在這種情況下，馬桶800內的右側比左側著水更多的除菌水或者自來水。The plan view of Fig. 16 (b) shows a state in which the disk 481b of the spray device 481 is rotated clockwise in a plan view. In this case, the right side of the toilet 800 has more sterilizing water or tap water than the left side.

圖16(c)的俯視圖表示噴霧裝置481的盤481b在俯視觀察的情況下呈逆時針旋轉時的樣子。在這種情況下，馬桶800內的左側比右側著水更多的除菌水或者自來水。The plan view of Fig. 16 (c) shows a state in which the disk 481b of the spray device 481 is rotated counterclockwise in a plan view. In this case, the left side of the toilet 800 has more sterilizing water or tap water than the water on the right side.

控制裝置405對噴霧裝置481的馬達481a進行控制，從而在便前噴霧模式中適當地切換低速旋轉和中速旋轉。藉此，能夠使除菌水或者自來水的水霧著水至馬桶800的各個角落。The control device 405 controls the motor 481a of the spray device 481 to appropriately switch between the low speed rotation and the medium speed rotation in the pre-dash spray mode. Thereby, it is possible to cause the mist of the sterilizing water or the tap water to reach the water to the corners of the toilet 800.

另外，控制裝置405較佳為對噴霧裝置481的馬達481a進行控制而在便前噴霧模式中(低速旋轉中以及中速旋轉中)適當地切換順時針旋轉和逆時針旋轉。藉此，左右方向上的水霧的分佈容易變得均勻。Further, the control device 405 preferably controls the motor 481a of the spray device 481 to appropriately switch the clockwise rotation and the counterclockwise rotation in the pre-spray mode (during low-speed rotation and medium-speed rotation). Thereby, the distribution of the water mist in the left-right direction is easily made uniform.

圖17是例示出實施方式的馬桶座裝置的便後噴霧模式下的動作的流程圖。
若人體感測器403檢測到使用者的入室(步驟S301：Yes)，則控制裝置405控制馬桶蓋用馬達512而打開馬桶蓋300，並打開電磁閥431，而使噴霧裝置481的馬達481a以及盤481b逆時針(CCW)中速旋轉(步驟S302)。藉由電磁閥431的打開，朝向盤481b的供水開始。Fig. 17 is a flowchart illustrating an operation in the post-spray mode of the toilet seat device of the embodiment.
If the human body sensor 403 detects the user's entrance (step S301: Yes), the control device 405 controls the toilet lid motor 512 to open the toilet lid 300, and opens the solenoid valve 431, so that the motor 481a of the spray device 481 and The disk 481b is rotated counterclockwise (CCW) at a medium speed (step S302). The water supply to the disk 481b is started by the opening of the solenoid valve 431.

控制裝置405將盤481b為中速旋轉的狀態維持預定時間(步驟S303：No)。藉此，能夠將盤481b上的殘留水從盤481b排出。此時，例如水霧擋板482被關閉，因此不向馬桶800內噴出水霧。The control device 405 maintains the state in which the disk 481b is rotated at a medium speed for a predetermined time (step S303: No). Thereby, the residual water on the disk 481b can be discharged from the disk 481b. At this time, for example, the water mist baffle 482 is closed, so that no water mist is sprayed into the toilet 800.

若經過預定時間(步驟S303：Yes)，則控制裝置405利用噴嘴馬達476使噴嘴473進入盆部801內。伴隨於此，水霧擋板482被打開(步驟S304)。藉此，開始進行自來水的水霧朝向馬桶800內的噴出。控制裝置405將從逆時針中速旋轉的盤481b噴出自來水的水霧的狀態維持預定時間(步驟S305：No)。When the predetermined time has elapsed (step S303: Yes), the control device 405 causes the nozzle 473 to enter the bowl portion 801 by the nozzle motor 476. Along with this, the water mist baffle 482 is opened (step S304). Thereby, the water mist of the tap water is started to be ejected toward the inside of the toilet 800. The control device 405 maintains the state in which the water mist of the tap water is ejected from the disk 481b that rotates counterclockwise at the medium speed for a predetermined time (step S305: No).

若經過預定時間(步驟S305：Yes)，則控制裝置405使噴霧裝置481的馬達481a以及盤481b順時針(CW)中速旋轉(步驟S306)。控制裝置405將從順時針中速旋轉的盤481b噴出自來水的水霧的狀態維持預定時間(步驟S307：No)。When the predetermined time has elapsed (step S305: Yes), the control device 405 causes the motor 481a of the spray device 481 and the disk 481b to rotate clockwise (CW) at a medium speed (step S306). The control device 405 maintains the state in which the water mist of the tap water is ejected from the disk 481b that rotates clockwise at a medium speed for a predetermined time (step S307: No).

若經過預定時間(步驟S307：Yes)，則控制裝置405使噴霧裝置481的馬達481a以及盤481b順時針(CW)低速旋轉(步驟S308)。控制裝置405將從順時針低速旋轉的盤481b噴出自來水的水霧的狀態維持預定時間(步驟S309：No)。When the predetermined time has elapsed (step S307: Yes), the control device 405 causes the motor 481a and the disk 481b of the spray device 481 to rotate at a low speed clockwise (CW) (step S308). The control device 405 maintains the state in which the water mist of the tap water is ejected from the disk 481b that rotates clockwise at a low speed for a predetermined time (step S309: No).

若經過預定時間(步驟S309：Yes)，則控制裝置405使噴霧裝置481的馬達481a以及盤481b逆時針(CCW)低速旋轉(步驟S310)。控制裝置405將從逆時針低速旋轉的盤481b噴出自來水的水霧的狀態維持預定時間(步驟S311：No)。When the predetermined time has elapsed (step S309: Yes), the control device 405 causes the motor 481a of the spray device 481 and the disk 481b to rotate counterclockwise (CCW) at a low speed (step S310). The control device 405 maintains the state in which the water mist of the tap water is ejected from the disk 481b rotated counterclockwise at a low speed for a predetermined time (step S311: No).

若經過預定時間(步驟S311：Yes)，則控制裝置405關閉電磁閥431(步驟S312)。控制裝置405將停止朝向盤481b的供水且使盤481b以低速旋轉的狀態維持預定時間(步驟S313：No)。藉此，能夠除去盤481b上的殘留水。When the predetermined time has elapsed (step S311: Yes), the control device 405 turns off the solenoid valve 431 (step S312). The control device 405 will stop the water supply to the disk 481b and maintain the disk 481b at a low speed for a predetermined time (step S313: No). Thereby, the residual water on the disk 481b can be removed.

若經過預定時間(步驟S313：Yes)，則控制裝置405停止馬達481a以及盤481b的旋轉，並利用噴嘴馬達476使噴嘴473向外殼400內後退。伴隨於此，水霧擋板482被關閉(步驟S314)。藉由以上過程，結束便前噴霧模式。When the predetermined time has elapsed (step S313: Yes), the control device 405 stops the rotation of the motor 481a and the disk 481b, and uses the nozzle motor 476 to retract the nozzle 473 into the casing 400. Along with this, the water mist baffle 482 is closed (step S314). By the above process, the pre-dose spray mode is ended.

控制裝置405在馬桶蓋300打開的狀態下執行便前噴霧模式。即，在便前噴霧模式中，在馬桶蓋300打開的狀態下噴出水霧。藉此，使用者不必等到便前噴霧模式的執行完成，就能夠立即就座於馬桶座部200。此外，在便前噴霧模式中，噴霧裝置481以不使水霧著水於馬桶座部200的方式進行噴霧，因此即便當使用者在便前噴霧模式的執行中就座於馬桶座部200的情況下，使用者被噴到水霧的可能性也低。The control device 405 executes the pre-spraying mode in a state where the toilet lid 300 is opened. That is, in the pre-spraying mode, the water mist is ejected while the toilet lid 300 is open. Thereby, the user can immediately sit on the toilet seat 200 without waiting for the execution of the front spray mode to be completed. Further, in the pre-spraying mode, the spray device 481 is sprayed so that the water mist does not immerse in the toilet seat 200, so that the user sits on the toilet seat 200 even when the user performs the pre-spray mode. In this case, the possibility that the user is sprayed with water mist is also low.

另一方面，控制裝置405在馬桶蓋300關閉的狀態下執行便後噴霧模式以及手動噴霧模式。即，在便後噴霧模式以及手動噴霧模式中，在馬桶蓋300關閉的狀態下噴出水霧。藉此，既能夠防止除菌水的水霧向馬桶外飛散，又能夠使除菌水的水霧擴散而在馬桶800、馬桶座部200以及馬桶蓋300等的大片範圍內抑制細菌、污垢。On the other hand, the control device 405 executes the post-spray mode and the manual spray mode in a state where the toilet lid 300 is closed. That is, in the post-dose spray mode and the manual spray mode, the water mist is ejected while the toilet lid 300 is closed. Thereby, it is possible to prevent the mist of the sterilizing water from scattering outside the toilet, and to spread the mist of the sterilizing water to suppress bacteria and dirt in a large range of the toilet 800, the toilet seat 200, and the toilet lid 300.

圖18是例示出實施方式的馬桶座裝置的動作的流程圖。
圖19(a)以及圖19(b)是例示出實施方式的馬桶座裝置的動作的示意圖。
在圖19(b)中，示出了除菌水或者自來水的水霧所著水的對象部位P1～P4。圖19(a)以“大”、“中”、“小”、“極小”4個階段示出了各噴霧模式下的各對象部位的著水量(每單位面積的著水量)。Fig. 18 is a flowchart illustrating an operation of the toilet seat apparatus of the embodiment.
19(a) and 19(b) are schematic views illustrating the operation of the toilet seat device of the embodiment.
In Fig. 19 (b), the target portions P1 to P4 of the water in the mist of the sterilizing water or the tap water are shown. Fig. 19 (a) shows the amount of water (the amount of water per unit area) of each target portion in each spray mode in four stages of "large", "medium", "small", and "minimum".

在便前噴霧模式中，在感測器402從沒有檢測到使用者的狀態變成檢測到使用者的狀態後，以不使除菌水或者自來水著水於馬桶座部200的方式，自動地將除菌水的水霧或者自來水的水霧向馬桶800內噴霧。In the pre-spray mode, after the sensor 402 changes from the state in which the user is not detected to the state in which the user is detected, the water is automatically prevented from passing the sterilizing water or the tap water to the toilet seat 200. The mist of the sterilizing water or the mist of the tap water is sprayed into the toilet 800.

例如，如圖18所示，若使用者進入到廁所從而人體感測器403檢測到使用者的入室，則表示使用者的入室的訊號(檢測資訊)被發送至控制裝置405。控制裝置405基於該訊號自動地執行便前噴霧模式。在便前噴霧模式中，控制裝置405使噴霧裝置481噴出自來水的水霧，從而使水霧著水於對象部位。如圖19(a)以及圖19(b)所示，便前噴霧模式中的對象部位是對象部位P3(盆緣部805的內壁面807)以及對象部位P4(盆部801)。在便前噴霧模式中，馬桶座部200以及盆緣部805的上表面806不是噴霧的對象部位。For example, as shown in FIG. 18, if the user enters the toilet and the human body sensor 403 detects the entrance of the user, the signal (detection information) indicating that the user has entered the room is transmitted to the control device 405. The control device 405 automatically executes the pre-spray mode based on the signal. In the pre-dash spray mode, the control device 405 causes the spray device 481 to eject a water mist of the tap water, thereby causing the water mist to lie on the target portion. As shown in FIGS. 19(a) and 19(b), the target portion in the pre-spray mode is the target portion P3 (the inner wall surface 807 of the bowl portion 805) and the target portion P4 (the bowl portion 801). In the pre-spray mode, the upper surface 806 of the toilet seat portion 200 and the bowl edge portion 805 is not the target portion of the spray.

如此，在馬桶座裝置100的使用前，藉由便前噴霧模式使除菌水或者自來水著水於馬桶800內。藉此，在污垢負荷大、對潤濕的允許度高的馬桶800內形成水膜，從而能夠抑制汙物的牢固黏著。另一方面，在污垢負荷小的馬桶座部200、盆緣部805的上表面806，即便不藉由便前噴霧模式形成水膜，也能夠在馬桶座裝置100的使用後藉由便後噴霧模式使除菌水著水，來抑制汙物的牢固黏著。為此，馬桶座裝置100在便前噴霧模式中使除菌水或者自來水的水霧以不著水於馬桶座部200的方式向馬桶800內噴出。藉此，藉由便前噴霧模式和便後噴霧模式，既能夠在馬桶800、馬桶座部200等的大片範圍內抑制細菌、污垢的產生，又能夠防止藉由便前噴霧模式噴出的除菌水或者自來水潤濕使用者。例如，即便在便前噴霧模式剛執行完使用者就用手轉動馬桶座部200或者就座於馬桶座部200的情況下，也能夠防止使用者的臀部、手與著水到馬桶座的除菌水或者自來水接觸。即，使用者不被水霧潤濕就能立即使用馬桶座裝置100。In this manner, before the toilet seat device 100 is used, the sterilizing water or the tap water is placed in the toilet 800 by the front spray mode. Thereby, a water film is formed in the toilet 800 which has a large dirt load and a high allowability for wetting, and it is possible to suppress the strong adhesion of the dirt. On the other hand, in the toilet seat portion 200 having a small dirt load and the upper surface 806 of the bowl edge portion 805, even if the water film is not formed by the front spray mode, the toilet seat device 100 can be sprayed after the use of the toilet seat device 100. The mode allows the sterilizing water to hydrate and inhibit the strong adhesion of the dirt. For this reason, the toilet seat apparatus 100 causes the mist of the sterilizing water or the tap water to be ejected into the toilet bowl 800 so as not to be in the toilet seat 200 in the pre-dose spray mode. Thereby, the pre-spray mode and the post-spray mode can suppress the generation of bacteria and dirt in a large range of the toilet 800, the toilet seat 200, and the like, and can prevent the sterilization by the pre-spray mode. Water or tap water wets the user. For example, even if the user sprays the toilet seat 200 or sits on the toilet seat 200 just after the user has finished performing the spray mode, the user's buttocks, hands and water can be prevented from being removed to the toilet seat. Contact with bacteria water or tap water. That is, the toilet seat device 100 can be used immediately without the user being wetted by the water mist.

並且，在便前噴霧模式中，藉由不使水霧著水於馬桶座部200，能夠在短時間內在馬桶800內形成水膜，從而能夠縮短便前噴霧模式的執行時間。進入到廁所的使用者不等到便前噴霧模式的結束就能夠使用馬桶座裝置100。Further, in the pre-spraying mode, by not allowing the water mist to lie on the toilet seat portion 200, the water film can be formed in the toilet 800 in a short time, and the execution time of the pre-spraying mode can be shortened. The user entering the toilet can use the toilet seat device 100 without waiting for the end of the spray mode.

此外，在便前噴霧模式中，“除菌水或者自來水不著水於馬桶座部”的範圍，不僅包括全部的水霧均不著水於馬桶座部200的情況，還可以包括微量的水霧著水於馬桶座部200的情況。例如，便前噴霧模式中著水於馬桶座部200的自來水或者除菌水的量，比便後噴霧模式或者手動噴霧模式中著水於馬桶座部200的除菌水的量少。但是，在便前噴霧模式中，著水於馬桶座部200的除菌水或者自來水的量較佳為盡可能少，例如較佳為零。In addition, in the pre-spray mode, the range of "sterilization water or tap water does not lie in the toilet seat" includes not only the entire water mist is not in the toilet seat 200 but also a trace amount of water. The case where the mist is in the toilet seat 200. For example, the amount of tap water or sterilizing water that is immersed in the toilet seat portion 200 in the front spray mode is smaller than the amount of sterilizing water that is immersed in the toilet seat portion 200 in the post-spray mode or the manual spray mode. However, in the pre-spray mode, the amount of the sterilizing water or the tap water that is immersed in the toilet seat 200 is preferably as small as possible, for example, preferably zero.

在便後噴霧模式中，在感測器402從檢測到使用者的狀態變成未檢測到使用者的狀態後，自動地將除菌水的水霧向馬桶800內以及馬桶座部200噴霧。In the post-dose spray mode, after the sensor 402 changes from the state in which the user is detected to the state in which the user is not detected, the mist of the sterilizing water is automatically sprayed into the toilet 800 and the toilet seat 200.

例如，如圖18所示，若使用者從廁所退出從而人體感測器403檢測到使用者離開，則表示使用者離開的訊號(檢測資訊)被發送至控制裝置405。控制裝置405基於該訊號自動地執行便後噴霧模式。在便後噴霧模式中，控制裝置405使除菌裝置450生成除菌水，使噴霧裝置481噴出除菌水的水霧，從而使水霧著水於對象部位。如圖19(a)以及圖19(b)所示，便後噴霧模式中的對象部位為對象部位P1(馬桶座部200的表面203)、對象部位P2(馬桶座部200的背面204以及盆緣部805的上表面806)、對象部位P3以及對象部位P4。For example, as shown in FIG. 18, if the user exits from the toilet and the human body sensor 403 detects that the user has left, the signal (detection information) indicating that the user has left is transmitted to the control device 405. The control device 405 automatically executes the post-salt spray mode based on the signal. In the post-dose spray mode, the control device 405 causes the sterilization device 450 to generate the sterilizing water, and causes the spray device 481 to eject the water mist of the sterilizing water, thereby causing the water mist to lie on the target portion. As shown in Fig. 19 (a) and Fig. 19 (b), the target portion in the post-spray mode is the target portion P1 (the surface 203 of the toilet seat portion 200), the target portion P2 (the back surface 204 of the toilet seat portion 200, and the basin). The upper surface 806 of the edge portion 805, the target portion P3, and the target portion P4.

如此，藉由便後噴霧模式的執行，從而在使用者使用馬桶座裝置100之後，能夠使除菌水自動地著水於馬桶800內以及馬桶座部200。藉此，不僅在馬桶800，還能夠在馬桶座部200等的大片範圍內自動地抑制細菌、污垢的產生。In this way, by the execution of the post-spray mode, after the user uses the toilet seat device 100, the sterilizing water can be automatically immersed in the toilet 800 and the toilet seat 200. Thereby, not only the toilet 800 but also the generation of bacteria and dirt can be automatically suppressed in a large range of the toilet seat 200 or the like.

此外，由於便後噴霧模式在使用者使用馬桶座裝置100之後執行，因此與使用前相比，容易確保長的非使用時間。因此，即便因便後噴霧模式而馬桶座部200、盆緣部805的上表面806被潤濕，也容易在下一次的使用前使馬桶座部200、盆緣部805的上表面806變乾。Further, since the post-dose spray mode is executed after the user uses the toilet seat device 100, it is easy to ensure a long non-use time as compared with before use. Therefore, even if the toilet seat portion 200 and the upper surface 806 of the bowl edge portion 805 are wetted by the post-spraying mode, it is easy to dry the upper surface 806 of the toilet seat portion 200 and the bowl edge portion 805 before the next use.

在手動噴霧模式中，在使用者對手動操作部500進行了操作後，將除菌水的水霧向馬桶800內以及馬桶座部200噴霧。In the manual spray mode, after the user operates the manual operation unit 500, the mist of the sterilizing water is sprayed into the toilet 800 and the toilet seat 200.

例如，如圖18所示，若使用者在廁所的入室過程中(例如便前噴霧模式的執行後)對手動操作部500進行操作，則與操作對應的訊號(操作資訊)被發送至控制裝置405。控制裝置405基於該訊號執行手動噴霧模式。手動噴霧模式在馬桶座裝置100的使用前/使用後/清掃時等時機被執行。在手動噴霧模式中，控制裝置405使除菌裝置450生成除菌水，使噴霧裝置481噴出除菌水的水霧，從而使水霧著水於對象部位。如圖19(a)以及圖19(b)所示，手動噴霧模式中的對象部位為對象部位P1、對象部位P2、對象部位P3以及對象部位P4。For example, as shown in FIG. 18, if the user operates the manual operation unit 500 during the entrance process of the toilet (for example, after the execution of the pre-spray mode), the signal (operation information) corresponding to the operation is transmitted to the control device. 405. Control device 405 performs a manual spray mode based on the signal. The manual spray mode is executed before, during, or after the use of the toilet seat device 100. In the manual spray mode, the control device 405 causes the sterilization device 450 to generate the sterilizing water, and causes the spray device 481 to eject the mist of the sterilizing water, thereby causing the water mist to immerse in the target portion. As shown in FIGS. 19( a ) and 19 ( b ), the target portions in the manual spray mode are the target portion P1 , the target portion P2 , the target portion P3 , and the target portion P4 .

如此，藉由手動噴霧模式，使除菌水著水於馬桶800內以及馬桶座部200，能夠進一步抑制細菌、污垢的產生。例如，針對難以藉由便後噴霧模式來抑制的牢固黏著污垢，藉由用衛生紙等擦掉已著水的除菌水，從而能夠除菌。使用者不使用專用的除菌紙就能夠簡單地進行擦拭除菌。
另外，例如對於在馬桶座裝置100的使用前介意馬桶座部200的污垢的使用者而言，能夠藉由手動噴霧模式對馬桶座部200進行除菌。由於基於使用者自身的操作來執行除菌，因此能夠提高使用者的安心感、滿足感。As described above, by the manual spray mode, the sterilizing water is allowed to immerse in the toilet 800 and the toilet seat 200, and the generation of bacteria and dirt can be further suppressed. For example, it is possible to remove bacteria by rubbing off the sterilized water that has been immersed in water by using a toilet paper or the like to adhere to the strong adhering dirt which is hard to be suppressed by the post-spraying mode. The user can simply perform sterilization by using a special sterilization paper.
Further, for example, for a user who minds the dirt of the toilet seat portion 200 before the toilet seat device 100 is used, the toilet seat portion 200 can be sterilized by a manual spray mode. Since the sterilization is performed based on the user's own operation, the user's feeling of satisfaction and satisfaction can be improved.

如圖18所示，對於控制裝置405而言，當在感測器檢測到使用者的狀態下執行手動噴霧模式後，即便感測器從檢測到使用者的狀態變成未檢測到使用者的上述狀態的情況下，也執行便後噴霧模式。藉此，即便在使用者使用馬桶座裝置100(排便、排尿)前執行了手動噴霧模式的情況下也執行便後噴霧模式，藉此能夠更確實地抑制細菌、污垢的產生。As shown in FIG. 18, for the control device 405, after the manual spray mode is executed in a state where the sensor detects the user, even if the sensor changes from detecting the state of the user to the above, the user is not detected. In the case of the state, the post-spray mode is also executed. Thereby, even if the manual spray mode is executed before the user uses the toilet seat device 100 (defecation and urination), the post-dose spray mode is executed, whereby the generation of bacteria and dirt can be more reliably suppressed.

但是，在手動噴霧模式剛結束使用者就已離開廁所的情況下，存在著水於馬桶座部200、盆緣部805的上表面806的除菌水未被擦掉的可能性。例如，如圖18所示，在馬桶座裝置100的使用後執行手動噴霧模式，並且從手動噴霧模式的結束起的第1預定時間T1以內感測器成為未檢測到使用者的狀態的情況下，存在除菌水殘留於馬桶座部200、盆緣部805的上表面806的可能性。However, when the user has left the toilet immediately after the manual spray mode is completed, there is a possibility that the sterilizing water of the toilet seat portion 200 and the upper surface 806 of the bowl edge portion 805 is not wiped off. For example, as shown in FIG. 18, the manual spray mode is executed after the use of the toilet seat apparatus 100, and the sensor becomes the state in which the user is not detected within the first predetermined time T1 from the end of the manual spray mode. There is a possibility that the sterilizing water remains on the upper surface 806 of the toilet seat portion 200 and the bowl edge portion 805.

因此，對於控制裝置405而言，在從手動噴霧模式的結束起的第1預定時間T1以內感測器從檢測到使用者的狀態變成未檢測到使用者的狀態的情況下，也可以不執行便後噴霧模式。或者，控制裝置405也可以使便後噴霧模式中噴霧裝置481所噴出的除菌水的量，相比在從手動噴霧模式的結束起經過第1預定時間T1後感測器從檢測到使用者的狀態變成未檢測到上述使用者的狀態的情況而言變少。藉此，能夠防止因便後噴霧模式而使得馬桶座部200、盆緣部805的上表面806被過度潤濕，導致除菌水向馬桶外滴下。第1預定時間T1例如為10秒～30秒左右。但是，第1預定時間T1並不限定於此，能夠適當地進行設定。Therefore, in the case where the control device 405 changes from the state in which the user is detected to the state in which the user is not detected within the first predetermined time T1 from the end of the manual spray mode, the control device 405 may not be executed. Spray mode after the toilet. Alternatively, the control device 405 may cause the amount of the sterilizing water sprayed by the spray device 481 in the post-spray spray mode to be detected from the sensor after the first predetermined time T1 elapses from the end of the manual spray mode. The state is such that the state of the user is not detected. Thereby, it is possible to prevent the upper surface 806 of the toilet seat portion 200 and the bowl edge portion 805 from being excessively wetted by the post-dose spray mode, and the sterilization water is dripped outside the toilet bowl. The first predetermined time T1 is, for example, about 10 seconds to 30 seconds. However, the first predetermined time T1 is not limited to this, and can be appropriately set.

另外，在便後噴霧模式剛結束就有下一個使用者進入到廁所的情況下，存在馬桶座部200、盆緣部805的上表面806正被除菌水潤濕的可能性。例如，在從便後噴霧模式的結束起的第2預定時間T2以內，下一個使用者進入到廁所而對手動操作部500進行了操作的情況下，有可能在馬桶座部200、盆緣部805的上表面806仍舊殘留有除菌水。Further, in the case where the next user enters the toilet immediately after the post-spray mode, there is a possibility that the upper surface 806 of the toilet seat portion 200 and the bowl edge portion 805 is being wetted by the sterilizing water. For example, in the case where the next user enters the toilet and operates the manual operation unit 500 within the second predetermined time T2 from the end of the post-drain spray mode, there is a possibility that the toilet seat portion 200 and the bowl edge portion are in the toilet seat portion 200 and the bowl edge portion. The upper surface 806 of the 805 still has sterilized water remaining.

為此，在從便後噴霧模式的結束起的第2預定時間T2以內操作手動操作部500的情況下，控制裝置405也可以不執行手動噴霧模式。或者，控制裝置405也可以使手動噴霧模式中噴霧裝置481所噴出的除菌水的量，相比在從便後噴霧模式的結束起經過第2預定時間T2後操作手動操作部500的情況而言變少。藉此，能夠防止因手動噴霧模式而使得馬桶座部200、盆緣部805的上表面806被過度潤濕，導致除菌水向馬桶外滴下。第2預定時間T2例如為10秒～30秒左右。但是，第2預定時間T2並不限定於此，能夠適當地進行設定。For this reason, when the manual operation unit 500 is operated within the second predetermined time T2 from the end of the post-drain spray mode, the control device 405 may not execute the manual spray mode. Alternatively, the control device 405 may cause the amount of the sterilizing water sprayed by the spray device 481 in the manual spray mode to be larger than the case where the manual operation unit 500 is operated after the lapse of the second predetermined time T2 from the end of the post-dose spray mode. Less words. Thereby, it is possible to prevent the upper surface 806 of the toilet seat portion 200 and the bowl edge portion 805 from being excessively wetted by the manual spray mode, and the sterilization water is dripped outside the toilet bowl. The second predetermined time T2 is, for example, about 10 seconds to 30 seconds. However, the second predetermined time T2 is not limited to this, and can be appropriately set.

另外，控制裝置405控制噴霧裝置，以使得手動噴霧模式中著水於馬桶座部200的除菌水的每單位面積的著水量(平均著水量)，比便後噴霧模式中著水於馬桶座部200的除菌水的每單位面積的除菌水的著水量(平均著水量)多。例如，如圖19(a)所示，在手動噴霧模式中，著水於對象部位P1以及對象部位P2的每單位面積的除菌水的量為“小”。另外，在便後噴霧模式中，著水於對象部位P1的每單位面積的除菌水的量為“極小”，著水於對象部位P2的每單位面積的除菌水的量為“小”。In addition, the control device 405 controls the spray device such that the amount of water per unit area of the sterilizing water that is immersed in the toilet seat 200 in the manual spray mode (the average amount of water) is greater than that in the toilet spray mode. The amount of water (average amount of water) per unit area of the sterilizing water of the sterilizing water of the part 200 is large. For example, as shown in FIG. 19( a ), in the manual spray mode, the amount of the sterilizing water per unit area of the target portion P1 and the target portion P2 is "small". Further, in the post-dose spray mode, the amount of the sterilizing water per unit area of the target portion P1 is "very small", and the amount of the sterilizing water per unit area of the target portion P2 is "small". .

如此，由於在便後噴霧模式中著水於馬桶座部200的除菌水的量比較少，所以能夠在便後噴霧之後使馬桶座部200在短時間內變乾。藉此，即便在便後噴霧之後使用者使用馬桶座裝置100的情況下，也能夠防止除菌水與使用者的手、臀部接觸。另外，由於在手動噴霧模式中著水於馬桶座部200的除菌水的量比較多，所以能夠使除菌水充分地浸透衛生紙等。藉此，能夠提高基於擦拭的除菌性能，並能夠抑制在擦拭時樹脂制的馬桶座部200受到損傷。因此，能夠兼得便後噴霧模式的乾燥性能與手動噴霧模式的擦拭性能。As described above, since the amount of the sterilizing water that is immersed in the toilet seat portion 200 in the post-spraying mode is relatively small, the toilet seat portion 200 can be dried in a short time after the post-spraying. Thereby, even when the user uses the toilet seat apparatus 100 after the post-scrapping, it is possible to prevent the sterilizing water from coming into contact with the user's hands and buttocks. Further, since the amount of the sterilizing water that is immersed in the toilet seat portion 200 in the manual spray mode is relatively large, the sterilizing water can be sufficiently saturated with the toilet paper or the like. Thereby, it is possible to improve the sterilization performance by wiping, and it is possible to suppress damage to the toilet seat portion 200 made of resin at the time of wiping. Therefore, it is possible to achieve both the drying performance in the post-spray mode and the wiping performance in the manual spray mode.

另外，如圖19(a)所示，在手動噴霧模式以及便後噴霧模式中，著水於對象部位P3以及對象部位P4的每單位面積的除菌水的量為“大”。另一方面，在便前噴霧模式中，著水於對象部位P3以及對象部位P4的每單位面積的除菌水的量為“中”。在馬桶座裝置100的使用後，藉由使大量的除菌水著水於馬桶800內，從而能夠進一步抑制細菌、污垢的產生。Further, as shown in FIG. 19( a ), in the manual spray mode and the post-spray spray mode, the amount of the sterilizing water per unit area of the target portion P3 and the target portion P4 is "large". On the other hand, in the pre-spraying mode, the amount of the sterilizing water per unit area of the target portion P3 and the target portion P4 is "medium". After the toilet seat device 100 is used, it is possible to further suppress the generation of bacteria and dirt by allowing a large amount of the sterilizing water to be immersed in the toilet 800.

另外，例如，控制裝置405對噴霧裝置進行控制，以使得在便後噴霧模式中噴出的除菌水的水霧的粒徑，比在便前噴霧模式中噴出的自來水(或者除菌水)的水霧的粒徑小。另外，控制裝置405對噴霧裝置進行控制，以使得在手動噴霧模式中噴出的除菌水的水霧的粒徑，比在便前噴霧模式中噴出的自來水(或者除菌水)的水霧的粒徑小。Further, for example, the control device 405 controls the spray device such that the particle size of the water mist of the sterilizing water sprayed in the post-dose spray mode is larger than that of the tap water (or the sterilized water) sprayed in the pre-dose spray mode. The particle size of the water mist is small. Further, the control device 405 controls the spray device such that the particle size of the water mist of the sterilizing water sprayed in the manual spray mode is larger than the water mist of the tap water (or the sterilized water) sprayed in the pre-dose spray mode. The particle size is small.

如此，藉由在便後噴霧模式以及手動噴霧模式中減小水霧的粒徑，從而除菌水的水霧容易向大範圍擴散。藉此，不僅在盆部801，還能夠在盆緣部805、馬桶座部200等的大片範圍內抑制細菌、污垢。在便前噴霧模式中，藉由增大水霧的粒徑，從而能夠在短時間內在盆部801、盆緣部805的內壁面807形成水膜。藉此，能夠在使用者就座於馬桶座部前結束便前噴霧模式。As described above, by reducing the particle size of the water mist in the post-dose spray mode and the manual spray mode, the water mist of the sterilizing water is easily diffused to a wide range. Thereby, it is possible to suppress bacteria and dirt in a wide range of the bowl portion 805, the toilet seat portion 200, and the like not only in the bowl portion 801. In the pre-dose spray mode, by increasing the particle size of the water mist, a water film can be formed on the inner wall surface 807 of the bowl portion 801 and the bowl edge portion 805 in a short time. Thereby, the pre-dash spray mode can be ended before the user sits on the toilet seat.

在實施方式中，控制裝置405在一次噴霧模式(例如一次便後噴霧模式)中對噴霧裝置481進行控制，以使得除菌水在馬桶座部200處的每單位面積的著水量、以及除菌水在盆緣部805的上表面806處的每單位面積的著水量，分別比除菌水在盆部801處的每單位面積的著水量小，且分別比除菌水在盆緣部805的內壁面807處的每單位面積的著水量小。In an embodiment, the control device 405 controls the spray device 481 in a single spray mode (eg, a one-time post-spray mode) such that the amount of water per unit area of the sterile water at the toilet seat 200, and sterilization The amount of water per unit area of the water at the upper surface 806 of the bowl edge portion 805 is smaller than the amount of water per unit area of the sterilizing water at the bowl portion 801, respectively, and is higher than that of the sterilizing water at the bowl edge portion 805, respectively. The amount of water per unit area at the inner wall surface 807 is small.

即，根據實施方式，在一次噴霧模式中，控制裝置405使著水於盆部801以及盆緣部805的內壁面807的除菌水的量比較多。藉由使大量的除菌水的水霧著水於污垢負荷大且對潤濕的允許度高的盆部801以及盆緣部805的內壁面807，能夠抑制細菌、污垢的產生。That is, according to the embodiment, in the one-time spray mode, the control device 405 relatively increases the amount of the sterilizing water that is placed on the inner wall surface 807 of the bowl portion 801 and the bowl portion 805. By causing a large amount of water of the sterilizing water to immerse in the water, the pot portion 801 having a high dirt load and high allowable humidity, and the inner wall surface 807 of the bowl portion 805 can suppress the generation of bacteria and dirt.

另外，根據實施方式，在一次噴霧模式中，控制裝置405使著水於馬桶座部200、盆緣部805的上表面806的除菌水的量比較少。馬桶座部200、盆緣部805的上表面806由於污垢負荷比較小，因此藉由使比較少量的除菌水著水，能夠抑制細菌、污垢。Further, according to the embodiment, in the one-time spray mode, the control device 405 relatively reduces the amount of the sterilizing water that is immersed in the upper surface 806 of the toilet seat portion 200 and the bowl edge portion 805. Since the upper surface 806 of the toilet seat portion 200 and the bowl edge portion 805 is relatively small in dirt load, it is possible to suppress bacteria and dirt by allowing a relatively small amount of the sterilizing water to converge.

另外，在對潤濕的允許度低的馬桶座部200、盆緣部805的上表面806，藉由使除菌水的著水量少，能夠在短時間內使馬桶座部200、盆緣部805的上表面806變乾。藉此，能夠防止除菌水與使用者的肌膚接觸、或者向馬桶外滴下。Further, in the toilet seat portion 200 and the upper surface 806 of the bowl edge portion 805, which have a low degree of wetting tolerance, the toilet seat portion 200 and the bowl edge portion can be made in a short time by reducing the amount of water for the sterilization water. The upper surface 806 of the 805 dries. Thereby, it is possible to prevent the sterilizing water from coming into contact with the skin of the user or dropping it to the outside of the toilet.

如此，根據實施方式，不僅在馬桶的盆部801，還能夠在盆緣部805以及馬桶座部200等的大片範圍內抑制細菌、污垢，且能夠防止除菌水與使用者的肌膚接觸而產生不適感、以及除菌水向馬桶外滴下。According to the embodiment, not only the bowl portion 801 of the toilet but also the bacteria, the dirt can be suppressed in a large range such as the bowl edge portion 805 and the toilet seat portion 200, and the sterilization water can be prevented from coming into contact with the skin of the user. Discomfort, as well as sterilizing water dripping out of the toilet.

例如，控制裝置405對噴霧裝置481進行控制，以使得在一次噴霧模式中馬桶座部200處的著水量(除菌水在馬桶座部處的每單位面積的著水量)成為著水於馬桶座部200的除菌水不滴落而是滯留的著水量。另外，控制裝置405對噴霧裝置進行控制，以使得在一次噴霧模式中盆緣部805的上表面806處的著水量(除菌水在盆緣部的上表面處的每單位面積的著水量)成為著水於盆緣部805的上表面806的除菌水不滴落而是滯留的著水量。For example, the control device 405 controls the spray device 481 such that the amount of water at the toilet seat 200 in one spray mode (the amount of water per unit area of the sterilizing water at the toilet seat) becomes water at the toilet seat. The sterilizing water of the portion 200 does not drip but the amount of water retained. Further, the control device 405 controls the spray device such that the amount of water at the upper surface 806 of the bowl portion 805 in the primary spray mode (the amount of water per unit area of the sterilizing water at the upper surface of the bowl portion) The amount of water that has accumulated in the water on the upper surface 806 of the bowl edge portion 805 does not drip but stays.

如此，由於在污垢負荷小的馬桶座部200、盆緣部805的上表面806，除菌水不滴落而是滯留，因此能夠將除菌水的氧化分解作用、漂白作用的時間確保為長，能夠抑制細菌、污垢的產生。另外，藉由使馬桶座部200、盆緣部805的上表面806處的著水量成為能夠滯留除菌水的著水量，從而能夠減少除菌水向馬桶外滴下的風險。In this way, since the sterilizing water does not drip but stays on the upper surface 806 of the toilet seat portion 200 and the bowl edge portion 805 having a small dirt load, the oxidative decomposition action and the bleaching action time of the sterilizing water can be ensured to be long. It can inhibit the production of bacteria and dirt. Further, by making the amount of water at the upper surface 806 of the toilet seat portion 200 and the bowl edge portion 805 the amount of water that can retain the sterilizing water, the risk of the sterilizing water dripping outside the toilet can be reduced.

並且，控制裝置405對噴霧裝置481進行控制，以使得在一次噴霧模式中盆部801處的著水量(除菌水在盆部處的每單位面積的著水量)成為著水於盆部801的除菌水滴落的著水量。另外，控制裝置405對噴霧裝置481進行控制，以使得在一次噴霧模式中盆緣部805的內壁面807處的著水量(除菌水在盆緣部的內壁面處的每單位面積的著水量)成為著水於盆緣部805的內壁面807的除菌水滴落的著水量。Further, the control device 405 controls the spray device 481 such that the amount of water at the bowl portion 801 (the amount of water per unit area of the sterilizing water at the bowl portion) in the one-time spray mode becomes water in the bowl portion 801. The amount of water that the sterilized water drops. Further, the control device 405 controls the spray device 481 such that the amount of water at the inner wall surface 807 of the bowl portion 805 in the primary spray mode (the amount of water per unit area of the sterilizing water at the inner wall surface of the bowl portion) The amount of water that has fallen into the water on the inner wall surface 807 of the bowl edge portion 805 is the amount of water that falls.

如此，藉由使除菌水在污垢負荷大的盆部801、盆緣部805的內壁面807滴落，從而不僅能夠利用氧化分解作用、漂白作用，也能夠利用藉由除菌水使污垢沖走的作用。藉此，能夠比使除菌水滯留的情況更有效地抑制細菌、污垢的產生。By allowing the sterilizing water to drip on the inner wall surface 807 of the bowl portion 801 and the bowl edge portion 805 having a large dirt load, it is possible to use not only the oxidative decomposition or the bleaching action but also the sterilizing by the sterilizing water. The role of walking. Thereby, it is possible to more effectively suppress the generation of bacteria and dirt than when the sterilization water is retained.

此外，“滴落”是指附著於物體的表面的水(例如除菌水)流下。“滴落”的範圍包括水滴、水膜因本身重量流動的情況、和因沖廁裝置的動作所產生的振動等而流動的情況。Further, "dropping" means that water (for example, sterilizing water) attached to the surface of the object flows down. The range of "drip" includes a case where water droplets, a water film flow by its own weight, and vibration due to vibration of the action of the flushing device.

例如，控制裝置405對噴霧裝置進行控制，以使得馬桶座部200處的著水量成為在馬桶座部200藉由馬桶座用馬達511(轉動裝置)而轉動時著水於馬桶座部200的除菌水不滴落而是滯留的著水量。For example, the control device 405 controls the spray device such that the amount of water at the toilet seat portion 200 becomes the drain of the toilet seat portion 200 when the toilet seat portion 200 is rotated by the toilet seat motor 511 (rotation device). The bacteria water does not drip but the amount of water retained.

藉此，即便在使馬桶座部200轉動的情況下，也能夠防止除菌水滴落，因此能夠將除菌水的氧化分解作用和漂白作用的作用時間確保為長，能夠進一步抑制細菌、污垢的產生。另外，藉由將馬桶座部200處的著水量設為能夠滯留除菌水的著水量，從而能夠減少除菌水向非預期的部位滴下的風險。In this way, even when the toilet seat portion 200 is rotated, it is possible to prevent the sterilizing water from falling, so that the oxidative decomposition action of the sterilizing water and the action time of the bleaching action can be ensured to be long, and the bacteria and the dirt can be further suppressed. produce. Further, by setting the amount of water at the toilet seat portion 200 to the amount of water that can retain the sterilizing water, it is possible to reduce the risk of the sterilizing water dropping to an unexpected portion.

對於上述般的著水量的控制，能夠藉由從噴霧裝置481噴出的水霧的粒徑的控制來進行。例如，控制裝置405對噴霧裝置481進行控制，以使得向馬桶座部200噴出的除菌水的水霧的粒徑、以及向盆緣部805的上表面806噴出的除菌水的水霧的粒徑，分別比向盆部801噴出的除菌水的水霧的粒徑小，並且分別比向盆緣部805的內壁面807噴出的除菌水的水霧的粒徑小。其中，向各部位噴出的除菌水的水霧的粒徑例如是指向各部位著水的水霧的粒徑。The control of the above-described general amount of water can be performed by controlling the particle size of the water mist sprayed from the spray device 481. For example, the control device 405 controls the spray device 481 such that the particle diameter of the water mist of the sterilizing water sprayed to the toilet seat portion 200 and the water mist of the sterilizing water sprayed onto the upper surface 806 of the bowl edge portion 805 The particle diameter is smaller than the particle diameter of the water mist of the sterilization water sprayed to the bowl portion 801, and is smaller than the particle diameter of the water mist of the sterilization water sprayed to the inner wall surface 807 of the bowl edge portion 805, respectively. The particle size of the water mist of the sterilization water sprayed to each part is, for example, the particle diameter of the water mist which is directed to each part.

由於著水於馬桶座部200以及盆緣部805的上表面806的除菌水的水霧的粒徑小，所以能夠使著水於馬桶座部以及盆緣部的上表面的除菌水不易流下。另外，由於著水於盆部801以及盆緣部805的內壁面807的除菌水的水霧的粒徑大，所以能夠使著水於盆部801以及盆緣部805的內壁面807的除菌水容易流下，能夠提高沖走污垢的作用。Since the particle size of the water mist of the sterilizing water in the toilet seat portion 200 and the upper surface 806 of the bowl edge portion 805 is small, it is possible to make it difficult to remove the sterilizing water on the upper surface of the toilet seat portion and the bowl edge portion. Flow down. In addition, since the water droplets of the sterilizing water in the inner wall surface 807 of the bowl portion 801 and the bowl portion 805 are large, the water can be removed from the inner wall surface 807 of the bowl portion 801 and the bowl portion 805. The bacteria water is easy to flow down, and the effect of flushing off dirt can be improved.

參照圖20(a)～圖20(e)對著水量(平均著水量)的測定方法進行說明。

馬桶座部200的每單位面積的著水量(平均著水量(g/cm2 ))，為表面203的每單位面積的著水量與背面204的每單位面積的著水量的平均值。The amount of water per unit area of the toilet seat portion 200 (the average amount of water (g/cm 2 )) is an average value of the amount of water per unit area of the surface 203 and the amount of water per unit area of the back surface 204.

如圖20的(c)所示，盆緣部805的上表面806具有位於前方側的前端區域806F、位於右側方的側方區域806R、以及位於左側方的側方區域806L。各區域的面積設為20平方公分(cm2 )。

如圖20(d)所示，盆緣部805的內壁面807具有位於前方側的前端區域807F、位於右側方的側方區域807R、以及位於左側方的側方區域807L。各區域的面積設為20平方公分(cm2 )。

如圖20的(e)所示，盆部801(盆部801的內側面中的未設置有存水的部分)具有位於前方側的前端區域801F、位於右側方的側方區域801R、以及位於左側方的側方區域801L。各區域的面積設為20平方公分(cm2 )。

圖20(a)～圖20(e)所示的各區域(203F、203L、203R、204F、204L、204R、806F、806L、806R、807F、807L、807R、801F、801L、以及801R各自)的每單位面積的著水量的測定方式如下。
首先，在噴出水霧後，用紙擦拭一定面積的區域，使紙吸收著水於該區域的水霧。接下來，將吸水前的紙的重量與吸水後的紙的重量之差作為著水於該區域的水霧的量(著水量)。對該著水量除以該區域的面積(擦拭的面積)，藉此計算該區域的每單位面積的著水量。20 (a) to 20 (e) of each of the regions (203F, 203L, 203R, 204F, 204L, 204R, 806F, 806L, 806R, 807F, 807L, 807R, 801F, 801L, and 801R) The amount of water per unit area is measured as follows.
First, after spraying the water mist, the area of a certain area is wiped with paper so that the paper absorbs the water mist of the water in the area. Next, the difference between the weight of the paper before water absorption and the weight of the paper after water absorption is taken as the amount of water mist (water amount) in the water. The amount of water is divided by the area of the area (the area wiped), thereby calculating the amount of water per unit area of the area.

圖21是例示出便後噴霧模式的水霧的著水量的圖表。
在圖21中，以“大”、“中”、“小”以及“極小”4個階段示出了圖20(a)～圖20(e)所示的各區域的每單位面積的著水量的大小關係。
例如，盆緣部805的上表面806的前端區域以及側方區域的每單位面積的著水量為“中”。與此相對地，馬桶座部200的表面203的前端區域以及側方區域的每單位面積的著水量為“極小”。Fig. 21 is a graph illustrating the amount of water of the water mist in the post-dose spray mode.
In Fig. 21, the amount of water per unit area of each region shown in Figs. 20(a) to 20(e) is shown in four stages of "large", "medium", "small", and "minimum". The size relationship.
For example, the amount of water per unit area of the front end region and the side region of the upper surface 806 of the bowl edge portion 805 is "medium". On the other hand, the amount of water per unit area of the front end region and the side region of the surface 203 of the toilet seat portion 200 is "very small".

即，控制裝置405對噴霧裝置481進行控制，以使得除菌水在盆緣部805的上表面806處的每單位面積的著水量，比除菌水在馬桶座部200的表面203處的每單位面積的著水量多。藉由令使用者直接接觸的可能性低的盆緣部805的上表面806處的除菌水的著水量，比使用者直接接觸的馬桶座部200的表面203多，藉此能夠抑制盆緣部805的上表面806處的細菌、污垢的產生。That is, the control device 405 controls the spray device 481 such that the amount of water per unit area of the sterilizing water at the upper surface 806 of the bowl portion 805 is higher than that of the sterilizing water at the surface 203 of the toilet seat portion 200. The amount of water per unit area is large. The amount of the sterilizing water at the upper surface 806 of the rim portion 805, which is less likely to be in direct contact with the user, is greater than the surface 203 of the toilet seat 200 directly in contact with the user, thereby suppressing the rim The production of bacteria and dirt at the upper surface 806 of the portion 805.

另外，在使用者就座於馬桶座部200進行排尿時，在馬桶座部200的背面204的前方側，容易附著因碰到盆部801、存水801w而濺起的尿液、汚水。因此，馬桶座部200的背面204的前方側，為污垢負荷比馬桶座部200的背面204的側方側大的部分。與此相對地，如圖21所示，馬桶座部200的背面204的前端區域的每單位面積的著水量為“大”，馬桶座部200的背面204的側方區域的每單位面積的著水量為“小”。In addition, when the user is seated in the toilet seat portion 200 to urinate, urine and sewage which are splashed by the basin portion 801 and the stored water 801w are easily attached to the front side of the back surface 204 of the toilet seat portion 200. Therefore, the front side of the back surface 204 of the toilet seat portion 200 is a portion where the dirt load is larger than the side of the back surface 204 of the toilet seat portion 200. On the other hand, as shown in FIG. 21, the amount of water per unit area of the front end region of the back surface 204 of the toilet seat portion 200 is "large", and the area per unit area of the side surface of the back surface 204 of the toilet seat portion 200 is The amount of water is "small".

即，在將馬桶座部200的比開口200a靠前方側的部位設定為前方部位、將開口200a的側方側設定為側方部位的情況下，控制裝置405對噴霧裝置481進行控制，以使得馬桶座部200的背面204的前方部位的除菌水的每單位面積的著水量(平均著水量)，比馬桶座部200的背面204的側方部位的除菌水的每單位面積的著水量(平均著水量)多。藉由使著水於前方側的除菌水的量比側方側多，能夠進一步抑制細菌、污垢在馬桶座部200的背面204處的產生。In other words, when the portion of the toilet seat portion 200 on the front side of the opening 200a is set as the front portion and the side of the opening 200a is set as the side portion, the control device 405 controls the spray device 481 to The amount of water per unit area of the sterilizing water in the front portion of the back surface 204 of the toilet seat portion 200 (the average amount of water) is larger than the area per unit area of the sterilizing water in the side portion of the back surface 204 of the toilet seat portion 200. The amount of water (average amount of water) is large. Since the amount of the sterilizing water on the front side is larger than that on the side, it is possible to further suppress the generation of bacteria and dirt on the back surface 204 of the toilet seat 200.

另外，由於使用者與馬桶座部200的背面204直接接觸的可能性比表面203低，因此馬桶座部200的背面204為對潤濕的允許度高的部分。另外，在馬桶座部200的背面204，容易附著因碰到盆部801、存水801w而濺起的尿液、汚水。因此，馬桶座部200的背面204為污垢負荷比馬桶座部200的表面203大的部分。針對於此，如圖21所示，控制裝置405對噴霧裝置481進行控制，以使得馬桶座部200的背面204處的除菌水的每單位面積的著水量比馬桶座部200的表面203處的除菌水的每單位面積的著水量多。Further, since the user is less likely to directly contact the back surface 204 of the toilet seat portion 200 than the surface 203, the back surface 204 of the toilet seat portion 200 is a portion having a high degree of tolerance to wetting. Further, in the back surface 204 of the toilet seat portion 200, urine and sewage which are splashed by the bowl portion 801 and the stored water 801w are easily adhered. Therefore, the back surface 204 of the toilet seat portion 200 is a portion where the dirt load is larger than the surface 203 of the toilet seat portion 200. To this end, as shown in FIG. 21, the control device 405 controls the spray device 481 such that the amount of water per unit area of the sterilizing water at the back surface 204 of the toilet seat 200 is higher than the surface 203 of the toilet seat 200. The sterilizing water has a large amount of water per unit area.

即，著水於馬桶座部200的背面204的除菌水的量比馬桶座部200的表面203多。藉由使著水於馬桶座部200的背面204的除菌水的量多，能夠抑制細菌、污垢的產生。That is, the amount of the sterilizing water that is immersed in the back surface 204 of the toilet seat portion 200 is larger than the surface 203 of the toilet seat portion 200. By causing a large amount of the sterilizing water to be applied to the back surface 204 of the toilet seat portion 200, generation of bacteria and dirt can be suppressed.

另外，如圖21所示，盆緣部805的內壁面807的前端區域以及側方區域的每單位面積的著水量為“大”，盆部801的前端區域以及側方區域的每單位面積的著水量為“大”。但是，直接著水於盆部801的前端區域以及側方區域的每單位面積的除菌水的量為“中”。Further, as shown in FIG. 21, the amount of water per unit area of the front end region and the side region of the inner wall surface 807 of the bowl edge portion 805 is "large", and the front end region of the bowl portion 801 and the unit area of the side region are The amount of water is "large." However, the amount of the sterilizing water per unit area of the front end region and the side region directly facing the water in the bowl portion 801 is "medium".

即，控制裝置405對噴霧裝置481進行控制，以使得直接著水於盆緣部805的內壁面807的除菌水的每單位面積的著水量(平均著水量)，比直接著水於盆部801的除菌水的每單位面積的著水量(平均著水量)多。其中，直接著水的除菌水的著水量不包括從上方流下來的除菌水的量。That is, the control device 405 controls the spray device 481 such that the amount of water per unit area of the sterilizing water directly immersed in the inner wall surface 807 of the bowl edge portion 805 (the average amount of water) is more directly than that of the basin. The sterilized water of 801 has a large amount of water per unit area (average amount of water). Among them, the amount of the sterilizing water directly flowing in the water does not include the amount of the sterilizing water flowing down from above.

在盆部801流動有馬桶清洗的清洗水，在盆緣部805的內壁面807不流動有馬桶清洗的清洗水。因此，盆緣部805的內壁面807的污垢負荷比盆部801大。為此，如上述般，藉由使直接著水於污垢負荷比較大的盆緣部805的內壁面807的除菌水的量多，能夠進一步抑制細菌、污垢在內壁面807處的產生。The washing water for washing the toilet is flowed through the bowl portion 801, and the washing water for washing the toilet does not flow on the inner wall surface 807 of the bowl edge portion 805. Therefore, the dirt load of the inner wall surface 807 of the bowl edge portion 805 is larger than that of the bowl portion 801. For this reason, as described above, the amount of the sterilizing water of the inner wall surface 807 of the bowl edge portion 805 which is directly immersed in the dirt load is large, and the generation of bacteria and dirt on the inner wall surface 807 can be further suppressed.

圖22(a)以及圖22(b)是例示出實施方式的粒徑的測定方法的立體圖。
在粒徑的測定中使用雷射衍射法。若向微粒照射雷射，則產生從該微粒朝向各種方向的衍射散射光。衍射散射光的強度在發光的方向上具有空間圖案。該空間圖案被稱為光強度分佈圖案。光強度分佈圖案根據微粒的粒徑而變化。利用微粒的粒徑與光強度分佈圖案的相關性，藉由檢測光強度分佈圖案，而能夠計算粒徑。22(a) and 22(b) are perspective views illustrating a method of measuring the particle diameter of the embodiment.
A laser diffraction method was used for the measurement of the particle diameter. When a laser is irradiated to the fine particles, diffraction scattered light is generated from the fine particles in various directions. The intensity of the diffracted scattered light has a spatial pattern in the direction of light emission. This spatial pattern is referred to as a light intensity distribution pattern. The light intensity distribution pattern varies depending on the particle diameter of the particles. The particle diameter can be calculated by detecting the light intensity distribution pattern by using the correlation between the particle diameter of the particles and the light intensity distribution pattern.

如圖22(a)以及圖22(b)所示，粒徑的測定裝置600具有發光部601和受光部602。受光部602設置為能夠接收發光部601所發出的雷射。在粒徑的測定中，將發光部601所發出的雷射向從噴霧裝置481噴出的水霧M照射。受光部602接收藉由雷射的照射而產生的衍射散射光。藉此，能夠對光強度分佈圖案進行檢測。測定裝置能夠使用Aerotrac LDSA-3500A(MicrotracBEL股份有限公司製)。As shown in FIGS. 22( a ) and 22 ( b ), the particle diameter measuring device 600 includes a light emitting unit 601 and a light receiving unit 602 . The light receiving unit 602 is provided to be capable of receiving the laser light emitted from the light emitting unit 601. In the measurement of the particle diameter, the laser light emitted from the light-emitting portion 601 is irradiated to the water mist M ejected from the spray device 481. The light receiving unit 602 receives the diffraction scattered light generated by the irradiation of the laser. Thereby, the light intensity distribution pattern can be detected. The measurement device can use Aerotrac LDSA-3500A (manufactured by Microtracbel Co., Ltd.).

圖23(a)以及圖23(b)是例示出實施方式的變形例的沖廁裝置的一部分的俯視圖以及剖面圖。
圖23(a)是從前方觀察沖廁裝置的一部分的俯視圖。圖23(b)是圖23(a)所示的A-A線的剖面圖。
如圖23(a)以及圖23(b)所示，在該例中，未設置有水霧擋板482，而是在外殼400設置有狹縫S。噴霧裝置481配置在外殼400內，狹縫S位於噴霧裝置481的前方下部。例如，狹縫S的上端面S1的高度(上下方向上的位置)與盤481b的底面B1的高度相同，上端面S1與底面B1在同一平面上。或者，上端面S1也可以比底面B1低。23(a) and 23(b) are a plan view and a cross-sectional view showing a part of a toilet device according to a modification of the embodiment.
Fig. 23 (a) is a plan view of a part of the flushing device viewed from the front. Fig. 23 (b) is a cross-sectional view taken along line AA shown in Fig. 23 (a).
As shown in FIGS. 23(a) and 23(b), in this example, the water mist baffle 482 is not provided, and the outer casing 400 is provided with the slit S. The spray device 481 is disposed in the outer casing 400, and the slit S is located at the lower front portion of the spray device 481. For example, the height (the position in the up-and-down direction) of the upper end surface S1 of the slit S is the same as the height of the bottom surface B1 of the disk 481b, and the upper end surface S1 and the bottom surface B1 are on the same plane. Alternatively, the upper end surface S1 may be lower than the bottom surface B1.

盤481b的上表面從水平傾斜，盤481b使水霧M相比於水平稍稍朝向下方噴出。從盤481b噴出的水霧M通過狹縫S而向盆部801內噴出。藉此，由於未設置有圖5所示般的水霧擋板482，因此不損害沖廁裝置的外觀設計性、清潔性，就能防止尿液等污垢Y附著於噴霧裝置481。The upper surface of the disk 481b is inclined from the horizontal, and the disk 481b causes the water mist M to be ejected slightly downward from the horizontal. The water mist M ejected from the disk 481b is ejected into the bowl portion 801 through the slit S. As a result, since the water mist baffle 482 as shown in FIG. 5 is not provided, it is possible to prevent the dirt Y such as urine from adhering to the spray device 481 without impairing the design and cleanability of the toilet device.

圖24是例示實施方式的變形例的沖廁裝置的主要部分結構的方塊圖。
其中，圖24一併示出了水路系統與電氣系統的主要部分結構。
如圖24所示，在該例子中，電磁閥431、除菌裝置450、切換閥472、噴霧裝置481、噴嘴馬達476、噴嘴473、噴嘴清洗室478以及流路110~113等被組裝於馬桶800的內部。另外，在該例子中，馬桶座用馬達511(轉動裝置)、馬桶蓋用馬達512(轉動裝置)、送風裝置513以及暖風加熱器514等被組裝於馬桶800的內部。另外，在該例子中，感測器402(例如人體感測器403、就座感測器404等)、控制裝置405被組裝於馬桶800的內部。Fig. 24 is a block diagram showing a configuration of a main part of a toilet device according to a modification of the embodiment.
Among them, Fig. 24 shows the main part structure of the waterway system and the electrical system.
As shown in Fig. 24, in this example, the electromagnetic valve 431, the sterilization device 450, the switching valve 472, the spray device 481, the nozzle motor 476, the nozzle 473, the nozzle cleaning chamber 478, and the flow paths 110 to 113 are assembled in the toilet.

Further, in this example, the toilet seat motor 511 (rotation device), the toilet lid motor 512 (rotation device), the air blowing device 513, the warm air heater 514, and the like are incorporated in the toilet 800. In addition, in this example, the sensor 402 (for example, the human body sensor 403, the seating sensor 404, etc.) and the control device 405 are assembled inside the toilet 800.

如此，在圖3所示的例子中被組裝於馬桶座裝置100的外殼400內部的各部件(以下，稱為“功能部”)也可以被組裝於馬桶800的內部。在功能部被組裝於馬桶800的內部的情況下，也能夠與功能部被組裝於外殼400的內部的情況同樣地使噴霧裝置481等動作。As described above, in the example shown in FIG. 3, each member (hereinafter referred to as a "functional portion") incorporated in the outer casing 400 of the toilet seat device 100 may be incorporated in the interior of the toilet 800. When the functional unit is incorporated in the interior of the toilet 800, the spray device 481 or the like can be operated similarly to the case where the functional portion is assembled inside the outer casing 400.

另外，在功能部如此被組裝於馬桶800的內部的情況下，馬桶座裝置100的外殼400可以被省略。或者，可以代替馬桶座裝置100而設置馬桶座部200與馬桶蓋300。在該情況下，例如馬桶座部200與馬桶蓋300分別被軸支為相對於馬桶800開閉自如。另外，在該情況下，例如噴嘴擋板479、水霧擋板482以及送風擋板516被軸支為能夠相對於馬桶800轉動。Further, in the case where the functional portion is thus assembled inside the toilet 800, the outer casing 400 of the toilet seat device 100 can be omitted. Alternatively, the toilet seat 200 and the toilet lid 300 may be provided instead of the toilet seat device 100. In this case, for example, the toilet seat portion 200 and the toilet lid 300 are respectively pivotally opened and closed with respect to the toilet bowl 800. Further, in this case, for example, the nozzle flapper 479, the water mist baffle 482, and the blower shutter 516 are pivotally supported to be rotatable relative to the toilet bowl 800.
