Description

本発明は、浴槽の洗浄を自動で行うことのできる浴槽洗浄装置に関する。   The present invention relates to a bathtub cleaning apparatus capable of automatically cleaning a bathtub.

従来の浴槽洗浄装置は、例えば、下記の特許文献1に示すように、浴槽に洗浄ノズルを設け、湯水供給配管を洗浄ノズルに接続すると共に湯水供給配管にベンチュリ部を設け、洗剤タンクの洗剤をベンチュリ部で湯水供給配管内を流れる湯水に混合して洗浄ノズルから洗剤と湯水の混合液(洗浄液)を浴槽の壁面に噴射して洗浄するようになっている。また、洗浄液を噴霧する前に浴槽の壁面に湯水を散布する予備すすぎを行い、浴槽内面の濡れ性を高めることにより、その後噴射される洗浄水が浴槽内面全体にわたって均一に浸潤するようにしている。   For example, as shown in Patent Document 1 below, a conventional bathtub cleaning device is provided with a cleaning nozzle in a bathtub, a hot water supply pipe is connected to the cleaning nozzle, a venturi is provided in the hot water supply pipe, and the detergent in the detergent tank is removed. In the venturi section, it is mixed with hot water flowing in the hot water supply pipe, and a cleaning liquid is sprayed from the cleaning nozzle onto the wall surface of the bathtub for cleaning. In addition, by preliminarily rinsing the hot water on the wall of the bathtub before spraying the cleaning liquid and improving the wettability of the inner surface of the bathtub, the cleaning water sprayed afterwards is uniformly infiltrated over the entire inner surface of the bathtub. .

洗浄液による洗浄効率を一層向上させたい場合には、給湯器から湯水供給配管(出湯配管)を介して供給される40〜50℃程度の湯水を用いて予備すすぎを所定時間行うことで、浴槽内空間を適度に温かな状態に保ち、汚れに対する洗剤成分の活性化や皮脂汚れの溶解を促進させている。給湯器の設置箇所と浴槽までの距離は様々であり、給湯器から湯水供給配管を介して供給される湯水の温度が所定温度に達するまでに時間を要する場合もあるため、従来は、給湯器が最も浴槽から離れている設置態様を想定して予備すすぎを比較的長い時間行っていた。   In order to further improve the cleaning efficiency with the cleaning liquid, the preliminary rinsing is performed for a predetermined time using hot water of about 40 to 50 ° C. supplied from the water heater through the hot water supply pipe (hot water supply pipe). It keeps the space in a moderately warm state and promotes the activation of detergent components against dirt and the dissolution of sebum dirt. The distance from the water heater installation location to the bathtub varies, and it may take time for the temperature of the hot water supplied from the water heater through the hot water supply piping to reach a predetermined temperature. However, the preliminary rinsing was performed for a relatively long time, assuming an installation mode that is farthest from the bathtub.

特開2007−117163号公報JP 2007-117163 A

1回の浴槽洗浄における予備すすぎの散布量として十数リットルの湯が必要であるため、年間総量として数千リットルの湯を予備すすぎに必要となるが、光熱費の更なる削減、環境性能の向上のために、給湯器と浴槽との設置態様に応じて効率的な予備すすぎを行うことが求められている。   Since more than a dozen liters of hot water is required as a pre-rinse application amount for a single bath wash, a total of thousands of liters of hot water is required per year for preliminary rinsing. For improvement, efficient preliminary rinsing is required in accordance with the installation mode of the water heater and the bathtub.

そこで本発明は、皮脂汚れの溶解及び洗剤成分の活性化のために浴槽洗浄初期の予備すすぎ時に散布する湯量を低減させることを目的とする。   Therefore, an object of the present invention is to reduce the amount of hot water sprayed at the time of preliminary rinsing in the early stage of bath cleaning in order to dissolve sebum dirt and activate detergent components.

上記目的を達成するために、本発明は、次の技術的手段を講じた。   In order to achieve the above object, the present invention takes the following technical means.

すなわち、本発明の浴槽洗浄装置は、給湯器から出湯配管を介して供給される湯水による予備すすぎを洗剤による洗浄前に行う浴槽洗浄装置であって、出湯配管から供給された湯水温度を予備すすぎ時に検知する温度検知手段(湯水温度検知手段)と、該温度検知手段により検知された湯水温度に基づいて予備すすぎの継続時間及び/又は湯水の積算流量を制御する制御手段とを備えていることを特徴とするものである(請求項1)。   That is, the bathtub cleaning device of the present invention is a bathtub cleaning device that performs preliminary rinsing with hot water supplied from a water heater via a hot water supply pipe before washing with a detergent, and preliminarily rinses the hot water temperature supplied from the hot water supply pipe. A temperature detecting means (hot water temperature detecting means) for detecting at times, and a control means for controlling the duration of preliminary rinsing and / or the integrated flow rate of hot water based on the hot water temperature detected by the temperature detecting means. (Claim 1).

かかる本発明の浴槽洗浄装置によれば、出湯配管から供給された後の湯水温度を予備すすぎ時に検知する温度検知手段を設けているので、給湯器が浴槽から離れて設置されていても、予備すすぎ時に浴槽内に噴射される湯水温度を浴槽直前で検知することができ、湯水温度が所定温度に達した場合にはその後の予備すすぎ時に散布する湯量を節減するように予備すすぎの継続時間や積算流量を制御することによって、給湯器が浴槽近くに配置されている場合や、夏場における予備すすぎ水量を低減できる。   According to the bathtub cleaning apparatus of the present invention, since the temperature detection means for detecting the hot water temperature after being supplied from the hot water supply pipe is provided at the time of preliminary rinsing, even if the water heater is installed away from the bathtub, The temperature of hot water sprayed into the bathtub at the time of rinsing can be detected immediately before the bathtub, and when the hot water temperature reaches a predetermined temperature, the duration of the preliminary rinsing can be reduced so as to save the amount of hot water sprayed during the subsequent preliminary rinsing. By controlling the integrated flow rate, it is possible to reduce the amount of preliminary rinse water when the water heater is disposed near the bathtub or in summer.

上記本発明の浴槽洗浄装置において、浴槽の排水口に設けられた電動式自動排水栓をさらに備え、前記制御手段は、予備すすぎ開始前に自動排水栓を開制御するとともに、予備すすぎの終了直前に自動排水栓を閉制御するように構成され、これにより予備すすぎ終了直前に出湯配管から供給された湯水を浴槽内に溜めるものであってよい(請求項2,4)。これによれば、予備すすぎ開始初期のよごれの多いすすぎ水は排水口から排水させられる。また、予備すすぎ終了間際の適温の湯水を浴槽内に少量溜めることにより、浴槽内を適度な温度と湿度に保つことができ、その後の洗剤による洗浄時に洗剤の浸透が活性化され、より一層の洗浄効率の向上が図られる。 The bathtub cleaning apparatus of the present invention further includes an electric automatic drain plug provided at a drain outlet of the bathtub, and the control means controls the opening of the automatic drain plug before starting the preliminary rinse and immediately before the end of the preliminary rinse. The automatic drain plug may be closed and controlled so that hot water supplied from the hot water supply pipe is stored in the bathtub immediately before the end of preliminary rinsing (claims 2 , 4 ). According to this, the rinsing water with much dirt at the beginning of the preliminary rinsing is drained from the drain outlet. In addition, by storing a small amount of hot water at an appropriate temperature just before the end of preliminary rinsing in the bathtub, the inside of the bathtub can be maintained at an appropriate temperature and humidity, and the penetration of the detergent is activated during the subsequent washing with the detergent. The cleaning efficiency is improved.

さらに、予備すすぎ終了後に浴槽内へ洗剤を散布する洗剤散布手段をさらに備え、前記制御手段は、洗剤散布手段による洗剤散布が終了する前に前記自動排水栓を開制御するように構成され、これにより予備すすぎ終了直前に浴槽内に溜められた前記湯水を洗剤散布手段による洗剤散布が終了する前に排水するものであってよい(請求項3,5)。これによれば、浴槽内に溜められた湯水の排水後に散布される洗剤によって、浴槽底面における洗剤の濃度が向上し、洗剤散布初期は湯水が溜められているために洗剤による洗浄効果がさほど期待できない浴槽底面をも、洗剤による洗浄効果により確実に洗浄できる。 Furthermore, it further comprises detergent spraying means for spraying detergent into the bathtub after completion of preliminary rinsing, and the control means is configured to control the opening of the automatic drain plug before the detergent spraying by the detergent spraying means ends. Thus, the hot water stored in the bathtub immediately before the end of preliminary rinsing may be drained before the spraying of the detergent by the detergent spraying means is completed (claims 3 and 5 ). According to this, the detergent sprayed after draining the hot water stored in the bathtub improves the concentration of the detergent on the bottom of the bathtub, and since the hot water is stored at the initial stage of spraying the detergent, the detergent cleaning effect is expected to be much Even the bottom of a bathtub that cannot be cleaned can be reliably cleaned by the cleaning effect of the detergent.

また、前記制御手段は、出湯配管から供給された湯水が所定温度に達したことを検知すると、該検知時点から所定時間経過したときに予備すすぎを終了するように構成されているものとすることができる。これによれば、出湯配管から供給される湯水が、皮脂汚れの溶解及び洗剤成分の活性化のために要求される温度に達した時点から、該湯水による一定時間の予備すすぎを行うことで、一定の洗浄性能を保証できる。 In addition, when the control means detects that the hot water supplied from the hot water supply pipe reaches a predetermined temperature, the control means is configured to finish the preliminary rinsing when a predetermined time elapses from the detection time point. It is Ru can. According to this, from the point in time when the hot water supplied from the tapping pipe reaches the temperature required for the dissolution of sebum dirt and the activation of the detergent components, by preliminarily rinsing with the hot water, A certain cleaning performance can be guaranteed.

また、出湯配管から供給される湯水の流量を検出する流量検出手段をさらに備え、前記制御手段は、出湯配管から供給された湯水が所定温度に達したことを検知すると、該検知時点からの湯水の積算流量が所定値に達したときに予備すすぎを終了するように構成されているものとすることができる(請求項)。これによれば、出湯配管から供給される湯水が、皮脂汚れの溶解及び洗剤成分の活性化のために要求される温度に達した時点から、一定の積算流量の湯水で予備すすぎを行うことで、一定の洗浄性能を保証できる。 Further, the apparatus further includes a flow rate detecting means for detecting a flow rate of hot water supplied from the hot water piping, and the control means detects hot water supplied from the hot water piping and reaches a predetermined temperature. When the integrated flow rate reaches a predetermined value, the preliminary rinsing can be terminated (claim 1 ). According to this, from the point in time when the hot water supplied from the hot water piping reaches the temperature required for the dissolution of sebum dirt and the activation of the detergent components, preliminary rinsing is performed with a constant amount of hot water. Can guarantee a certain cleaning performance.

また、本発明の浴槽洗浄装置は、給湯器から出湯配管を介して供給される湯水による予備すすぎを洗剤による洗浄前に行う浴槽洗浄装置であって、浴槽周辺の雰囲気温度を検知するための雰囲気温度検知手段と、該雰囲気温度検知手段により検知された雰囲気温度に基づいて予備すすぎの継続時間及び/又は湯水の積算流量を制御する制御手段とを備えていることを特徴とするものである(請求項6)。   Further, the bathtub cleaning device of the present invention is a bathtub cleaning device that performs preliminary rinsing with hot water supplied from a water heater through a hot water supply pipe before cleaning with a detergent, and an atmosphere for detecting the ambient temperature around the bathtub It is characterized by comprising temperature detection means and control means for controlling the duration of preliminary rinsing and / or the integrated flow rate of hot water based on the atmospheric temperature detected by the atmospheric temperature detection means ( Claim 6).

かかる本発明の浴槽洗浄装置によれば、浴槽周辺の雰囲気温度を検知するための浴槽温度検知手段を設けているので、予備すすぎ時に浴槽周辺の雰囲気温度を検知することができ、雰囲気温度に応じて予備すすぎの継続時間や積算流量を制御することによって、夏場など浴槽周辺の雰囲気温度が比較的高い場合における予備すすぎ水量を低減できる。一方、例えば、冬場など浴槽周辺の雰囲気温度が比較的低い場合には十分な量の湯水による予備すすぎを行うことで浴槽内温度を十分に上昇させ、浴槽内を適度な温度と湿度に保つことで、その後の洗剤による洗浄時に洗剤の浸透が活性化され、洗浄効率の向上が図られる。また、浴槽周辺の雰囲気温度に応じて予備すすぎの継続時間や積算流量を制御することで、最も配管長の長い設置態様にあわせて一律の長いすすぎ継続時間を設定する必要がなく、給湯器と浴槽との設置態様に応じて効率的な予備すすぎを行うことができる。   According to the bathtub cleaning apparatus of the present invention, since the bathtub temperature detecting means for detecting the ambient temperature around the bathtub is provided, the ambient temperature around the bathtub can be detected during preliminary rinsing, and the ambient temperature depends on the ambient temperature. By controlling the duration of the preliminary rinsing and the integrated flow rate, it is possible to reduce the amount of preliminary rinsing water when the ambient temperature around the bathtub is relatively high, such as in summer. On the other hand, for example, when the ambient temperature around the bathtub is relatively low, such as in winter, the temperature in the bathtub is sufficiently increased by pre-rinsing with a sufficient amount of hot and cold water, so that the temperature in the bathtub is maintained at an appropriate temperature and humidity. Thus, the penetration of the detergent is activated during the subsequent washing with the detergent, and the washing efficiency is improved. In addition, by controlling the duration and cumulative flow rate of preliminary rinsing according to the ambient temperature around the bathtub, there is no need to set a uniform long rinsing duration according to the installation mode with the longest pipe length. Efficient preliminary rinsing can be performed according to the installation mode with the bathtub.

上記本発明の浴槽洗浄装置において、出湯配管から供給された湯水温度を予備すすぎ時に検知する湯水温度検知手段をさらに備えることができ、前記制御手段は、前記雰囲気温度及び前記湯水温度に基づいて予備すすぎの継続時間及び/又は湯水の積算流量を制御するように構成することができる(請求項)。これによれば、出湯配管から供給された後の湯水温度を予備すすぎ時に検知する湯水温度検知手段を設けているので、給湯器が浴槽から離れて設置されていても、予備すすぎ時に浴槽内に噴射される湯水温度を浴槽直前で検知することができ、湯水温度が所定温度に達した場合にはその後の予備すすぎ時に散布する湯量を節減するように予備すすぎの継続時間や積算流量を制御することによって、給湯器が浴槽近くに配置されている場合や、夏場における予備すすぎ水量を低減できる。 The bathtub cleaning apparatus of the present invention may further include hot water temperature detecting means for detecting the hot water temperature supplied from the hot water piping at the time of preliminary rinsing, and the control means reserves based on the ambient temperature and the hot water temperature. The rinsing duration and / or the integrated flow rate of hot water can be controlled (claim 6 ). According to this, since the hot water temperature detecting means for detecting the hot water temperature after being supplied from the hot water supply pipe is detected at the time of preliminary rinsing, even if the water heater is installed away from the bathtub, The temperature of the injected hot water can be detected immediately before the bathtub, and when the hot water temperature reaches a predetermined temperature, the duration of the preliminary rinsing and the integrated flow rate are controlled so as to reduce the amount of hot water sprayed during the subsequent preliminary rinsing. By this, when the water heater is arrange | positioned near the bathtub, the amount of preliminary | backup rinse water in summer can be reduced.

また、前記制御手段は、出湯配管から供給された湯水が所定温度に達したことを検知すると、該検知時点から前記雰囲気温度に応じて定められた所定時間経過したときに予備すすぎを終了するように構成されているものとすることができる。これによれば、出湯配管から供給される湯水が、皮脂汚れの溶解及び洗剤成分の活性化のために要求される温度に達するまでのすすぎ継続時間が湯水温度に応じて制御される。さらに、出湯配管から供給される湯水が、皮脂汚れの溶解及び洗剤成分の活性化のために要求される温度に達した時点から予備すすぎ終了までの予備すすぎ継続時間が、前記雰囲気温度に応じて制御される。このように湯水温度及び雰囲気温度に応じて予備すすぎ継続時間を制御することで、一定の洗浄性能を保証できる。 In addition, when the control means detects that the hot water supplied from the hot water supply pipe has reached a predetermined temperature, the preliminary rinsing is terminated when a predetermined time determined according to the ambient temperature has elapsed from the detection time. Ru can be assumed to be configured. According to this, the rinse continuation time until the hot water supplied from the hot water supply pipe reaches the temperature required for the dissolution of sebum dirt and the activation of the detergent component is controlled according to the hot water temperature. Further, the preliminary rinsing duration from the time when the hot water supplied from the hot water supply piping reaches the temperature required for the dissolution of sebum dirt and the activation of the detergent component depends on the ambient temperature. Be controlled. Thus, by controlling the preliminary rinsing duration according to the hot and cold water temperature and the ambient temperature, it is possible to guarantee a certain cleaning performance.

また、出湯配管から供給される湯水の流量を検出する流量検出手段をさらに備え、前記制御手段は、出湯配管から供給された湯水が所定温度に達したことを検知すると、該検知時点からの湯水の積算流量が前記雰囲気温度に応じて定められた所定値に達したときに予備すすぎを終了するように構成することができる(請求項)。これによれば、出湯配管から供給される湯水が、皮脂汚れの溶解及び洗剤成分の活性化のために要求される温度に達するまでのすすぎ継続時間が湯水温度に応じて制御される。さらに、出湯配管から供給される湯水が、皮脂汚れの溶解及び洗剤成分の活性化のために要求される温度に達した時点から予備すすぎ終了までの積算流量が、前記雰囲気温度に応じて制御される。このように湯水温度及び雰囲気温度に応じて予備すすぎ継続時間若しくは積算流量を制御することで、一定の洗浄性能を保証できる。 Further, the apparatus further includes a flow rate detecting means for detecting a flow rate of hot water supplied from the hot water piping, and the control means detects hot water supplied from the hot water piping and reaches a predetermined temperature. When the integrated flow rate reaches a predetermined value determined according to the ambient temperature, the preliminary rinsing can be terminated (claim 6 ). According to this, the rinse continuation time until the hot water supplied from the hot water supply pipe reaches the temperature required for the dissolution of sebum dirt and the activation of the detergent component is controlled according to the hot water temperature. Furthermore, the integrated flow rate from the point when the hot water supplied from the hot water supply pipe reaches the temperature required for the dissolution of sebum dirt and the activation of the detergent components to the end of the preliminary rinsing is controlled according to the ambient temperature. The Thus, by controlling the preliminary rinsing duration or the integrated flow rate according to the hot water temperature and the ambient temperature, it is possible to guarantee a certain cleaning performance.

また、浴槽の排水口に設けられた電動式自動排水栓をさらに備え、前記制御手段は、予備すすぎ開始前に自動排水栓を開制御するとともに、予備すすぎの終了直前に自動排水栓を閉制御するように構成され、これにより予備すすぎ終了直前に出湯配管から供給された湯水を浴槽内に溜めるように構成できる(請求項7,9)。これによれば、予備すすぎ開始初期のよごれの多いすすぎ水は排水口から排水させられる。また、予備すすぎ終了間際の適温の湯水を浴槽内に少量溜めることにより、浴槽内を適度な温度と湿度に保つことができ、その後の洗剤による洗浄時に洗剤の浸透が活性化され、より一層の洗浄効率の向上が図られる。 In addition, an electric automatic drain plug provided at the drain of the bathtub is further provided, and the control means controls the opening of the automatic drain plug before the start of preliminary rinsing and closes the automatic drain plug immediately before the end of preliminary rinsing. Accordingly, the hot water supplied from the hot water supply pipe immediately before the end of preliminary rinsing can be configured to be stored in the bathtub (claims 7 and 9 ). According to this, the rinsing water with much dirt at the beginning of the preliminary rinsing is drained from the drain outlet. In addition, by storing a small amount of hot water at an appropriate temperature just before the end of preliminary rinsing in the bathtub, the inside of the bathtub can be maintained at an appropriate temperature and humidity, and the penetration of the detergent is activated during the subsequent washing with the detergent. The cleaning efficiency is improved.

さらに、予備すすぎ終了後に浴槽内へ洗剤を散布する洗剤散布手段をさらに備え、前記制御手段は、洗剤散布手段による洗剤散布が終了する前に前記自動排水栓を開制御するように構成され、これにより予備すすぎ終了直前に浴槽内に溜められた前記湯水を洗剤散布手段による洗剤散布が終了する前に排水するように構成できる(請求項8,10)。これによれば、浴槽内に溜められた湯水の排水後に散布される洗剤によって、浴槽底面における洗剤の濃度が向上し、洗剤散布初期は湯水が溜められているために洗剤による洗浄効果がさほど期待できない浴槽底面をも、洗剤による洗浄効果により確実に洗浄できる。 Furthermore, it further comprises detergent spraying means for spraying detergent into the bathtub after completion of preliminary rinsing, and the control means is configured to control the opening of the automatic drain plug before the detergent spraying by the detergent spraying means ends. Thus, the hot water stored in the bathtub immediately before the end of the preliminary rinsing can be drained before the detergent spraying by the detergent spraying means is finished (claims 8 and 10 ). According to this, the detergent sprayed after draining the hot water stored in the bathtub improves the concentration of the detergent on the bottom of the bathtub, and since the hot water is stored at the initial stage of spraying the detergent, the detergent cleaning effect is expected to be much Even the bottom of a bathtub that cannot be cleaned can be reliably cleaned by the cleaning effect of the detergent.

上記洗浄ノズル10は浴槽2の底壁を貫通して設置され先端開口から内壁面に向けて所定範囲の広がりをもって洗浄用湯水を噴出するようになっている。この洗浄ノズル10として、図例では1つのみを図示しているが、浴槽2のサイズや構造に応じて2以上のものを所定配置にて設置してもよい。又、この浴槽2の底壁には電動式自動排水栓23が設置され、この排水栓23は、制御部7からの制御信号に基づいて電気的に作動される開閉駆動機構24からの開閉駆動力の伝達を受けて開閉作動されるようになっている。なお、この開閉駆動機構24は浴槽2の上面側に設置され、この開閉駆動機構24にはその作動状態(排水栓23が開状態か閉状態か)の如何を検出する排水栓状態検出センサ(図示省略)が設けられている。上記洗浄配管11は、その上流端が出湯配管31に接続され下流端が上記の洗浄ノズル10に連通接続されたものであり、上記注湯電磁弁15を開くことで、熱源機3から出湯配管31を介して湯水が洗浄配管11に供給されるようになっている。   The washing nozzle 10 is installed so as to penetrate the bottom wall of the bathtub 2 and jets hot water for washing with a predetermined range from the front end opening toward the inner wall surface. Although only one cleaning nozzle 10 is illustrated in the figure, two or more cleaning nozzles 10 may be installed in a predetermined arrangement depending on the size and structure of the bathtub 2. An electric automatic drain plug 23 is installed on the bottom wall of the bathtub 2, and the drain plug 23 is opened / closed from an opening / closing drive mechanism 24 that is electrically operated based on a control signal from the control unit 7. It opens and closes upon receiving force. The open / close drive mechanism 24 is installed on the upper surface side of the bathtub 2, and the open / close drive mechanism 24 has a drain plug state detection sensor (for detecting whether the drain plug 23 is open or closed). (Not shown) is provided. The cleaning pipe 11 has an upstream end connected to the hot water discharge pipe 31 and a downstream end connected to the cleaning nozzle 10. The hot water supply solenoid valve 15 is opened to open the hot water supply pipe 3 from the heat source unit 3. Hot water is supplied to the cleaning pipe 11 via 31.

上記ベンチュリ管19には洗剤供給管21の下流端が連通接続されており、この洗剤供給管21の上流端は洗剤タンク20に連通接続されている。洗剤電磁弁22の開作動により洗剤タンク20から供給される所定量の洗剤がベンチュリ管19において通過する洗浄用湯水に対し負圧吸引作用により混合されるようになっており、洗剤電磁弁22を1回の洗浄に対し閉弁状態から開作動させて開弁状態にさせている開弁時間の長短によって洗剤供給量の調整が可能となっている。これら洗剤タンク20、洗剤供給管21,洗剤電磁弁22、ベンチュリ管19、洗浄配管11並びに洗浄ノズル10によって、洗剤を浴槽2内に散布するための洗剤散布手段が構成されている。   A downstream end of a detergent supply pipe 21 is connected to the venturi pipe 19, and an upstream end of the detergent supply pipe 21 is connected to a detergent tank 20. A predetermined amount of detergent supplied from the detergent tank 20 by the opening operation of the detergent solenoid valve 22 is mixed with the washing hot water passing through the venturi pipe 19 by a negative pressure suction action. The detergent supply amount can be adjusted according to the length of the valve opening time in which the valve is opened from the closed state for one washing. The detergent tank 20, the detergent supply pipe 21, the detergent solenoid valve 22, the venturi pipe 19, the washing pipe 11, and the washing nozzle 10 constitute detergent spraying means for spraying detergent into the bathtub 2.

上記の浴槽洗浄装置1の各作動要素13,15,22,24は、洗浄ノズル10による浴槽2内を洗浄するための洗浄制御等を実行する洗浄制御手段としての制御部7によって作動制御されるとともに、制御部7から電源供給がなされるようになっている。この制御部7には洗浄運転操作用の洗浄リモコン6及び流量センサ14が電気的に接続されている。   The operation elements 13, 15, 22, and 24 of the bathtub cleaning device 1 are controlled by the control unit 7 as a cleaning control unit that executes cleaning control for cleaning the inside of the bathtub 2 by the cleaning nozzle 10. At the same time, power is supplied from the control unit 7. The controller 7 is electrically connected to a cleaning remote controller 6 for cleaning operation and a flow sensor 14.

上記制御部7は、マイクロコンピュータ及びRAMやROMなどの記憶手段を内蔵して、記憶手段に記憶されたプログラムや制御データ等に基づいて浴槽洗浄装置1の各作動要素を作動制御する。この制御内容の一実施例を図3及び図4に示し、当該実施例の洗浄制御動作について以下説明する。   The said control part 7 incorporates memory | storage means, such as a microcomputer and RAM, ROM, and controls operation of each action | operation element of the bathtub washing apparatus 1 based on the program, control data, etc. which were memorize | stored in the memory | storage means. An example of this control content is shown in FIGS. 3 and 4, and the cleaning control operation of this embodiment will be described below.

洗浄リモコン5の洗浄運転スイッチをオンするか、あるいは洗浄リモコン5によって設定された予約時間になると洗浄運転が開始され(S1)、まず自動排水栓23を開制御して(S2)、浴槽2内の浴槽水が排水されるまで待機する(S3)。かかる待機は、所定時間の経過を待つものとしてもよく、また、自動排水栓23に水量センサを設けて排水流量が無くなるまで待機するものとしてもよい。   When the cleaning operation switch of the cleaning remote controller 5 is turned on or the reserved time set by the cleaning remote controller 5 is reached, the cleaning operation is started (S1). First, the automatic drain plug 23 is controlled to open (S2), and the inside of the bathtub 2 Wait until the bathtub water is drained (S3). Such standby may be a wait for a lapse of a predetermined time, or may be a standby until a drainage flow is exhausted by providing a water amount sensor in the automatic drain plug 23.

浴槽水の排水が完了すると、注湯電磁弁15を開制御するとともに水量サーボ13の調節を行い(S4,S5)、予め設定された所定流量の湯水が熱源機3から出湯配管31を介して供給させ、供給された湯水による予備洗浄を開始する。このとき、熱源機3からの出湯温度が異常に高温となっていないか、及び、設定された流量に収束するかの検査を行い(S6,S7)、異常が検出されれば洗浄リモコン6等により異常報知して、以降の制御を緊急停止する。   When the drainage of the bath water is completed, the hot water solenoid valve 15 is controlled to open and the water amount servo 13 is adjusted (S4, S5), and a predetermined flow rate of hot water is supplied from the heat source unit 3 via the hot water supply pipe 31. Supply and start pre-cleaning with the supplied hot water. At this time, it is inspected whether the temperature of the hot water from the heat source unit 3 is not abnormally high and whether it converges to the set flow rate (S6, S7). Is notified of an abnormality, and the subsequent control is urgently stopped.

次に、水温センサ9の検出値に基づいて注湯電磁弁15を開いてから供給される湯水が適温となるまでの所定の最大待ち時間を経過したか否かを判定し(S8)、最大待ち時間を経過したときは、供給される湯水が適温となることを待たずに、次のステップS10へと以降し、最大待ち時間を経過するまでは出湯配管31から洗浄配管11に供給された湯水の温度が適温となるまで待機する(S9)。かかる判定制御により、水温センサ9により検知された湯水温度に基づいて予備すすぎの継続時間を制御部7が制御するように構成されている。すなわち、最大待ち時間が経過する前に湯水温度が適温となれば、すぐに次のステップへ移行することで、予備すすぎ開始から湯水温度が適温となるまでの経過時間と最大待ち時間との差分だけ予備すすぎ継続時間を短縮する。   Next, based on the detection value of the water temperature sensor 9, it is determined whether or not a predetermined maximum waiting time until the supplied hot water reaches an appropriate temperature after opening the hot water solenoid valve 15 is reached (S8). When the waiting time has elapsed, without waiting for the supplied hot water to reach an appropriate temperature, the process proceeds to the next step S10 and is supplied from the hot water supply pipe 31 to the cleaning pipe 11 until the maximum waiting time elapses. Wait until the temperature of the hot water reaches an appropriate temperature (S9). With this determination control, the control unit 7 is configured to control the duration of the preliminary rinsing based on the hot water temperature detected by the water temperature sensor 9. That is, if the hot water temperature reaches an appropriate temperature before the maximum waiting time elapses, the process immediately proceeds to the next step, so that the difference between the elapsed time from the start of preliminary rinsing until the hot water temperature reaches the appropriate temperature and the maximum waiting time is reached. Only reduce the preliminary rinsing duration.

最大待ち時間が経過するか、或いは、供給された湯水温度が適温に達すると、その時点からの予備すすぎ時間を計測するためにタイマーTを初期化し(S10)、所定時間、例えば60秒を経過すると洗剤と湯水の混合液からなる洗浄液による洗浄動作に移行する(S13)。また、本実施例では、予備すすぎ時間の終了直前、例えば10秒前に自動排水栓23を閉制御することにより、予備すすぎ終了直前に出湯配管31から洗浄配管11に供給された湯水を浴槽2内に少量溜めるためのステップS11,S12が設けられている。ここで浴槽2内に溜められる湯水の量は、洗浄ノズル10からの洗浄液の噴射に影響のない程度の量となされている。   When the maximum waiting time elapses or when the supplied hot water temperature reaches an appropriate temperature, a timer T is initialized to measure the preliminary rinsing time from that time (S10), and a predetermined time, for example, 60 seconds elapses. Then, the process proceeds to a cleaning operation using a cleaning liquid composed of a mixture of detergent and hot water (S13). Further, in this embodiment, the automatic drain plug 23 is controlled to be closed immediately before the end of the preliminary rinsing time, for example, 10 seconds before the hot water supplied to the cleaning pipe 11 from the hot water discharge pipe 31 immediately before the end of the preliminary rinsing. Steps S11 and S12 are provided for storing a small amount therein. Here, the amount of hot water stored in the bathtub 2 is set so as not to affect the jetting of the cleaning liquid from the cleaning nozzle 10.

予備すすぎが終了すると、次に、洗浄水の噴射の繰返し回数を例えば3に設定して(S14)、洗剤と湯水の混合液からなる洗浄液を洗浄ノズル10から上記繰返し回数だけ間欠的に噴射させる(S15〜S24)。各回ごとの洗浄液の制御フローとしては、例えば、タイマーTを初期化し(S15)、洗剤電磁弁22と注湯電磁弁15とを開制御することによって洗剤と湯水の混合液からなる洗浄液を洗浄ノズル10から噴射させ(S16)、所定時間、例えば2秒間洗浄液を噴射すると洗剤電磁弁22と注湯電磁弁15とを閉制御して(S17,S18)、洗浄液が浴槽2の壁面に浸潤するまで所定時間、例えば15秒間待機する(S22)。このとき、最終回の洗浄液の噴射直前の待機状態のとき(C=2のとき)であれば、待機時間の途中、例えば、最終回の洗浄液の噴射の5秒前に自動排水栓23を開制御することにより(ステップS20,S21)、予備すすぎ終了時に浴槽2内に溜められた湯水を排水するようにしている。これにより、最終の(3回目の)洗浄液の噴射によって、浴槽2の底面にも最適な濃度の洗浄液を浸潤させることができ、該洗浄液によって浴槽底面をも洗浄可能となる。   When the preliminary rinsing is completed, the number of repetitions of cleaning water injection is set to 3 (S14), for example, and a cleaning liquid composed of a mixture of detergent and hot water is intermittently injected from the cleaning nozzle 10 by the number of repetitions described above. (S15-S24). As a control flow of the cleaning liquid for each time, for example, the timer T is initialized (S15), and the cleaning electromagnetic valve 22 and the pouring electromagnetic valve 15 are controlled to open, thereby cleaning the cleaning liquid composed of the detergent and hot water mixture with the cleaning nozzle. 10 (S16), when the cleaning liquid is sprayed for a predetermined time, for example, 2 seconds, the detergent electromagnetic valve 22 and the pouring electromagnetic valve 15 are closed (S17, S18) until the cleaning liquid infiltrates the wall surface of the bathtub 2 Wait for a predetermined time, for example, 15 seconds (S22). At this time, if it is in a standby state immediately before the final cleaning liquid injection (when C = 2), the automatic drain plug 23 is opened during the standby time, for example, 5 seconds before the final cleaning liquid injection. By controlling (steps S20 and S21), hot water stored in the bathtub 2 is drained at the end of preliminary rinsing. As a result, the final (third) spray of the cleaning liquid can infiltrate the cleaning liquid having the optimum concentration into the bottom surface of the bathtub 2, and the bottom surface of the bathtub can be cleaned with the cleaning liquid.

上記の待機時間が経過すると(S22)、繰返し回数をカウントして(S23)、所定の繰返し回数の洗浄液の噴射を実行した場合には(S24)、注湯電磁弁15を開いて(S15)、熱源機3から出湯配管31を介して供給される湯水によるすすぎ動作を所定時間行い(S26)、所定時間のすすぎ動作を終了すると水量サーボ13及び注湯電磁弁15を閉制御して(S27)、洗浄運転を終了する(S28)。   When the above standby time has elapsed (S22), the number of repetitions is counted (S23), and when a predetermined number of repetitions of cleaning liquid injection have been performed (S24), the hot water solenoid valve 15 is opened (S15). Then, a rinsing operation with hot water supplied from the heat source unit 3 through the hot water piping 31 is performed for a predetermined time (S26), and when the rinsing operation for the predetermined time is completed, the water amount servo 13 and the pouring electromagnetic valve 15 are controlled to be closed (S27). ), The cleaning operation is terminated (S28).

本発明は上記実施形態に限定されるものではなく、適宜設計変更できる。例えば、図3に示す制御フローにおいて、予備すすぎ開始後出湯配管31から供給される湯水が適温になった後に、所定時間を経過するか否かの制御を行う例を示したが、供給される湯水の積算流量を計測して、積算流量が所定値となったときに予備すすぎを終了するように制御してもよい。また、予備すすぎの継続時間や積算流量は、出湯配管31から供給される湯水温度に応じて可変させることもでき、例えば、湯水温度が48℃の場合には予備すすぎを1分継続させるが、湯水温度が32℃の場合には予備すすぎを1分20秒継続させることができる。これにより、湯水温度によって浴槽内の雰囲気温度に差が生じることで、低温時に十分な予備すすぎが行われないことを防止できる。   The present invention is not limited to the above-described embodiment, and the design can be changed as appropriate. For example, in the control flow shown in FIG. 3, an example is shown in which control is performed as to whether or not a predetermined time has elapsed after the hot water supplied from the hot water supply pipe 31 after the start of preliminary rinsing has reached an appropriate temperature. It is also possible to control so that the preliminary rinsing is terminated when the accumulated flow rate of hot water is measured and the accumulated flow rate reaches a predetermined value. In addition, the duration of the preliminary rinsing and the integrated flow rate can be varied in accordance with the hot water temperature supplied from the tap water pipe 31. For example, when the hot water temperature is 48 ° C., the preliminary rinsing is continued for 1 minute. When the hot water temperature is 32 ° C., the preliminary rinsing can be continued for 1 minute and 20 seconds. Thereby, it can prevent that sufficient preliminary rinse is not performed at the time of low temperature because the difference in the atmospheric temperature in a bathtub arises with hot water temperature.

また、上記実施形態では制御部7を洗浄リモコン6とは別に設けたが、洗浄リモコン6に制御部7を一体に内蔵してもよい。   In the above embodiment, the control unit 7 is provided separately from the cleaning remote controller 6, but the control unit 7 may be integrated in the cleaning remote controller 6.

また、上記実施形態では自動排水栓23を最終の洗浄液の噴射直前に開制御したが(図4の実施例1参照)、図4の実施例2に示すように、洗浄液による洗浄が完了するまで自動排水栓23を閉じておいて、最終のすすぎ動作開始時又は開始直前に自動排水栓23を開制御するように構成してもよい。   In the above embodiment, the automatic drain plug 23 is controlled to be opened immediately before the final cleaning liquid is sprayed (see Example 1 in FIG. 4). As shown in Example 2 in FIG. 4, until the cleaning with the cleaning liquid is completed. The automatic drain plug 23 may be closed, and the automatic drain plug 23 may be controlled to open at the start or just before the final rinse operation.

また、上記実施形態では出湯配管から供給された湯水温度に基づいて予備すすぎの継続時間及び/又は湯水の積算流量を制御したが、湯水温度に代えて、若しくは、湯水温度に加えて浴槽周辺の雰囲気温度に基づいて予備すすぎの継続時間及び/又は湯水の積算流量を制御することもできる。図5は、かかる雰囲気温度に基づく制御を採用する本発明の他の実施形態を示しており、浴槽2の周辺の雰囲気温度を検知するための雰囲気温度検知手段としてのサーミスタ8が洗剤タンク20に取付けられており、このサーミスタ8の検知信号は制御部7に入力されている。   Further, in the above embodiment, the duration of preliminary rinsing and / or the integrated flow rate of hot water is controlled based on the hot water temperature supplied from the hot water piping, but instead of the hot water temperature or in addition to the hot water temperature, Based on the ambient temperature, the duration of preliminary rinsing and / or the integrated flow rate of hot water can be controlled. FIG. 5 shows another embodiment of the present invention that employs the control based on the ambient temperature, and a thermistor 8 as an ambient temperature detection means for detecting the ambient temperature around the bathtub 2 is provided in the detergent tank 20. The detection signal of the thermistor 8 is input to the control unit 7.

そして、本実施形態では、制御部7によって、供給される湯水温度による上記実施形態の予備すすぎ継続時間の短縮制御に加えて、浴槽周辺の雰囲気温度によって予備すすぎの継続時間若しくは積算流量が適切に制御されるように構成されている。かかる制御フローの一例を図6に示しており、上記実施形態と同様の工程については省略し、異なる構成、作用効果について以下説明する。   And in this embodiment, in addition to the shortening control of the preliminary rinse continuation time of the said embodiment by the hot water temperature supplied by the control part 7, the duration or integrated flow rate of preliminary rinse is appropriately set according to the ambient temperature around the bathtub. It is configured to be controlled. An example of such a control flow is shown in FIG. 6, and steps similar to those in the above embodiment are omitted, and different configurations and operational effects will be described below.

本実施形態では、予備すすぎのための注湯電磁弁15を開く前(ステップS3とステップS4の間)に、サーミスタ8の検知信号に基づいて浴槽周辺の雰囲気温度を検出するステップが設けられている。予備すすぎ開始前に雰囲気温度を検出するようにしたのは、予備すすぎの湯水によって浴槽壁面温度が上昇し、これに伴いサーミスタ8の検出値に影響が出て正しい雰囲気温度が検出困難となるからである。当該ステップで検出された雰囲気温度は、制御部7内のメモリに記憶される。   In the present embodiment, before opening the pouring solenoid valve 15 for preliminary rinsing (between step S3 and step S4), a step of detecting the ambient temperature around the bathtub based on the detection signal of the thermistor 8 is provided. Yes. The reason why the ambient temperature is detected before the start of preliminary rinsing is that the bath wall surface temperature is increased by the hot water in the preliminary rinsing, and accordingly, the detection value of the thermistor 8 is affected, making it difficult to detect the correct ambient temperature. It is. The ambient temperature detected in this step is stored in a memory in the control unit 7.

また、予備すすぎ開始後(ステップS4)、最大待ち時間が経過するか(ステップS8)或いは供給される湯温が適温となったことを検出したとき(ステップS9)、タイマーTを上記実施形態と同様に初期化するとともに、その時点からの予備すすぎ継続時間Bを、上記ステップにおいて制御部7に記憶された雰囲気温度及び注湯温度(供給される湯水温度)に基づいて、雰囲気温度が高いほど継続時間Bが短く、且つ、注湯温度が高いほど継続時間Bが短くなるように設定する(ステップS10)。なお、注湯温度としては、水温センサ9の検出値を用いてもよいし、注湯温度を設定するリモコンの設定値を用いてもよい。   In addition, after the start of preliminary rinsing (step S4), when the maximum waiting time has elapsed (step S8) or when it is detected that the supplied hot water temperature has reached an appropriate temperature (step S9), the timer T is set to the above embodiment. Similarly, the preliminary rinsing continuation time B from that time point is set higher based on the atmospheric temperature and the pouring temperature (the supplied hot water temperature) stored in the control unit 7 in the above step. The duration B is set to be shorter as the duration B is shorter and the pouring temperature is higher (step S10). In addition, as a pouring temperature, the detection value of the water temperature sensor 9 may be used, and the setting value of the remote control which sets pouring temperature may be used.

上記継続時間Bの設定は、湯水温度及び雰囲気温度を変数とする所定の数式に基づいて行ってもよいが、本実施形態では、下記の表1に示す予め設定されたテーブルに基づいて行っている。なお、下記表1では、最大待ち時間が経過するか或いは湯温が適温になった時点からの予備すすぎ継続時間Bの長さを設定したが、当該時点以降の予備すすぎ用の湯水の積算流量を設定することもできる。また、湯水温度を考慮せず、雰囲気温度のみに基づいて継続時間Bを設定することも可能である。   The setting of the duration time B may be performed based on a predetermined mathematical formula having the hot water temperature and the ambient temperature as variables, but in the present embodiment, the duration B is performed based on a preset table shown in Table 1 below. Yes. In Table 1 below, the length of the preliminary rinsing duration B from the time when the maximum waiting time elapses or the hot water temperature reaches an appropriate temperature is set. However, the integrated flow rate of hot water for preliminary rinsing after that time is set. Can also be set. It is also possible to set the duration B based only on the ambient temperature without considering the hot water temperature.

Figure 0006205705

また、ステップS11,S13では、設定された継続時間Bを上記所定時間(段落0032第2行目参照)としてタイマーTと比較している。   In steps S11 and S13, the set duration time B is compared with the timer T as the predetermined time (see the second line of the paragraph 0032).

図7は本実施形態の浴槽洗浄装置1の予備すすぎ動作時の時間経過と注湯温度との関係を示している。図示された予備すすぎ開始時点に注湯電磁弁15が開制御されて湯水の供給が開始され、その後注湯温度が徐々に上昇して所定の適温となるまでの継続時間Aは上記ステップS9の判定により注湯温度に応じて可変とされ、さらに、注湯温度が適温となった時点から予備すすぎ終了までの継続時間Bも注湯温度及び雰囲気温度に応じて可変とされている。   FIG. 7 shows the relationship between the passage of time and the pouring temperature during the preliminary rinsing operation of the bathtub cleaning device 1 of the present embodiment. The pouring solenoid valve 15 is controlled to open at the start of the preliminary rinsing shown in the figure, and the supply of hot water is started. Thereafter, the duration A from when the pouring temperature gradually rises to a predetermined appropriate temperature is determined in step S9. According to the determination, the temperature is variable according to the pouring temperature, and the duration B from the time when the pouring temperature reaches an appropriate temperature to the end of the preliminary rinsing is also variable according to the pouring temperature and the ambient temperature.

このように供給される湯水温度のみならず浴槽周辺の雰囲気温度に基づいて予備すすぎ継続時間を適切に制御することによって、雰囲気温度が常温若しくはそれ以上の環境下などにおいて浴槽内が直ぐに温まるにもかかわらず予備すすぎ時に無駄にお湯を流し続ける必要がなく、予備すすぎの継続時間及び湯水積算流量を節減して、各設置環境に応じた運転によりランニングコストを抑えることができる。   By appropriately controlling the preliminary rinsing duration based not only on the temperature of the hot water supplied in this way but also on the ambient temperature around the bathtub, the interior of the bathtub can be warmed immediately in an environment where the ambient temperature is normal or higher. Regardless of this, it is not necessary to keep the hot water flowing unnecessarily at the time of preliminary rinsing, and the running time can be reduced by the operation according to each installation environment by reducing the duration of the preliminary rinsing and the accumulated water flow rate.
