The room temperature sensor 24a is not particularly limited, and is provided closer to the air suction side than the filters 16t and 16f (see FIG. 2). By this, for example, when the indoor heat exchanger 12 is frozen for cleaning, the detection error due to the influence of the heat radiation can be suppressed. The indoor temperature sensor 24a constitutes a temperature detection unit that detects the temperature of the air in this embodiment.

溼度感測器24b乃是檢測室內(被空調空間)的空氣的溼度之感測器，設置在室內機10的特規定位置。溼度感測器24b並沒有特別限定，設置在與室內溫度感測器24a同樣的地方，構成可以檢測隨著室內風扇14的旋轉並透過空氣吸入口h1等所取入的空氣的溼度。溼度感測器24b係構成本實施方式中檢測空氣的溼度之溼度檢測部。The humidity sensor 24b is a sensor that detects the humidity of the air in the room (air-conditioned space), and is installed at a specific position of the indoor unit 10. The humidity sensor 24b is not particularly limited, and is installed in the same place as the indoor temperature sensor 24a, and is configured to detect the humidity of the air taken in through the air suction port h1 and the like as the indoor fan 14 rotates. The humidity sensor 24b constitutes a humidity detection unit that detects the humidity of the air in this embodiment.

室內熱交換器溫度感測器24c乃是檢測室內熱交換器12(參閱圖2)的溫度之感測器，設置在室內熱交換器12。室內溫度感測器24a、溼度感測器24b及室內熱交換器溫度感測器24c的檢測值，係輸出到室內控制電路25。尚且，說明的實施方式中，例示了室內溫度感測器24a、溼度感測器24b及室內熱交換器溫度感測器24c，但是，也可以設置其他的感測器。The indoor heat exchanger temperature sensor 24c is a sensor for detecting the temperature of the indoor heat exchanger 12 (refer to FIG. 2), and is installed in the indoor heat exchanger 12. The detection values of the indoor temperature sensor 24a, the humidity sensor 24b, and the indoor heat exchanger temperature sensor 24c are output to the indoor control circuit 25. Furthermore, in the described embodiment, the indoor temperature sensor 24a, the humidity sensor 24b, and the indoor heat exchanger temperature sensor 24c are exemplified, but other sensors may be provided.

除菌物質產生部26乃是產生除菌物質也就是規定的離子(例如，OH- )之靜電去除器，設置在室內機10的內部。可以在圖2表示的室內機10的空氣吹出口h3的附近設置除菌物質產生部26(未圖示。)。藉此，可以在停止室內風扇14的狀態下對室內熱交換器12等進行除菌，而且，也可以在室內風扇14的驅動中把除菌物質供給到被空調空間。The sterilization material generating unit 26 is a static electricity eliminator that generates a sterilization material, that is, a predetermined ion (for example, OH − ), and is installed in the indoor unit 10. The sterilizing substance generating unit 26 (not shown) may be provided in the vicinity of the air outlet h3 of the indoor unit 10 shown in FIG. 2. Thereby, the indoor heat exchanger 12 and the like can be sterilized while the indoor fan 14 is stopped, and the sterilizing substance can also be supplied to the air-conditioned space while the indoor fan 14 is being driven.

除菌物質產生部26雖未圖示，但是，具備：針狀的放電電極、以及彎曲成包圍該放電電極之感應電極。接著，除菌物質產生部26係在放電電極及介電電極間施加規定的高電壓，產生電暈放電，產生除菌物質也就是OH- 等。Although not shown in the figure, the sterilizing substance generating unit 26 includes a needle-shaped discharge electrode and an induction electrode bent to surround the discharge electrode. Next, the sterilization substance generating unit 26 applies a predetermined high voltage between the discharge electrode and the dielectric electrode to generate corona discharge, and generate the sterilization substance, that is, OH − and the like.

尚且，在說明的實施方式中，說明了除菌物質產生部26產生OH- 作為除菌物質的情況，但是並不限定於此。例如，除菌物質產生部26也可以產生O2- 等的離子作為除菌物質。而且，可以適宜設定放電電極及介電電極間的電壓等，來讓除菌物質產生部26產生OH自由基作為除菌物質。而且，可以適宜設定放電電極及介電電極間的電壓等，來讓除菌物質產生部26產生臭氧(O3 )作為除菌物質。如此，除了除菌物質也就是離子，也可以藉由自由基或臭氧，來進行室內熱交換器12的除菌。而且，也可以藉由除菌物質產生部26，產生OH- 、OH自由基、臭氧等混合存在的除菌物質。亦即，除菌物質產生部26也可以產生規定的離子、自由基及臭氧中至少一個之除菌物質。In addition, in the described embodiment, the case where the sterilizing substance generating unit 26 produces OH − as the sterilizing substance has been described, but it is not limited to this. For example, the sterilizing substance generating unit 26 may generate ions such as O 2- as the sterilizing substance. In addition, the voltage between the discharge electrode and the dielectric electrode can be appropriately set so that the sterilizing substance generating unit 26 generates OH radicals as the sterilizing substance. In addition, the voltage between the discharge electrode and the dielectric electrode can be appropriately set so that the sterilizing substance generating unit 26 generates ozone (O 3 ) as the sterilizing substance.

Hereinafter, the indoor control circuit 25 and the outdoor control circuit 37 are summarized and referred to as "control part K".

以下，關於本實施方式所致之空調機100，說明其基本的動作。空調機100係回應透過了遙控器40的利用者所致之操作，接受運轉指令、停止指令、設定溫度的變更指令及運轉狀態的變更(冷房或暖房等的運轉狀態的指定)指令，進行空調運轉。空調機100接受運轉指令的話，以現在設定的運轉狀態來開始空調運轉。Hereinafter, the basic operation of the air conditioner 100 according to this embodiment will be described. The air conditioner 100 responds to the operation made by the user through the remote controller 40, accepts operation commands, stop commands, set temperature change commands, and operation status changes (designation of the operating status of the cooling room or heating room, etc.), and performs air conditioning. Running. When the air conditioner 100 receives the operation command, it starts the air-conditioning operation in the currently set operation state.

作為空調機100所具有的運轉狀態，是有冷房運轉、暖房運轉、除溼運轉及送風運轉。更進一步，也可以是配合環境自動切換冷房運轉、暖房運轉、除溼運轉及送風運轉之自動運轉。As the operating states of the air conditioner 100, there are cooling operation, heating operation, dehumidification operation, and air blowing operation. Furthermore, it can also be an automatic operation that automatically switches between cooling operation, heating operation, dehumidification operation, and air supply operation according to the environment.

在冷房運轉中，控制部K係如圖3以虛線箭頭表示般，切換四通閥35使室內熱交換器12作為蒸發器發揮作用、使室外熱交換器32作為凝結器發揮作用，並驅動壓縮機31。接著，控制部K係藉由驅動室內風扇14，把從圖2表示的空氣吸入口h1等所取入的室內空氣，用室內熱交換器12來冷卻，並從控制上下風向板19成開狀態的空氣吹出口h3吹出，藉此，把設置室內機10的室內(被空調空間)進行冷房。在冷房運轉中，室內熱交換器12作為蒸發器發揮作用的緣故，室內熱交換器12為浸溼的狀態，室內機的內部通常為高溼度狀態。During the cooling operation, the control unit K switches the four-way valve 35 to make the indoor heat exchanger 12 function as an evaporator and the outdoor heat exchanger 32 to function as a condenser as shown by the dotted arrow in FIG.机31. Next, the control unit K drives the indoor fan 14 to cool the indoor air taken in from the air suction port h1 and the like shown in FIG. The air outlet h3 blows out, thereby cooling the room (air-conditioned space) in which the indoor unit 10 is installed. During the cooling operation, because the indoor heat exchanger 12 functions as an evaporator, the indoor heat exchanger 12 is in a wet state, and the interior of the indoor unit is usually in a high humidity state.

在暖房運轉中，如圖3實線箭頭表示，控制部K係切換四通閥35使室內熱交換器12作為凝結器發揮作用、使室外熱交換器32作為蒸發器發揮作用，並驅動壓縮機31。接著，控制部K以使室內風扇14驅動的方式，把從圖2表示的空氣吸入口h1等所取入的室內空氣，用室內熱交換器12來加熱，並從控制上下風向板19成開狀態的空氣吹出口h3吹出，藉此，把設置室內機10的室內(被空調空間)進行暖房。During heating operation, as indicated by the solid arrow in FIG. 3, the control unit K switches the four-way valve 35 to make the indoor heat exchanger 12 function as a condenser, the outdoor heat exchanger 32 to function as an evaporator, and drive the compressor 31. Next, the control unit K drives the indoor fan 14 to heat the indoor air taken in from the air suction port h1 and the like shown in FIG. The air blowing port h3 in the state blows out, thereby heating the indoor (air-conditioned space) in which the indoor unit 10 is installed.

於除溼運轉，配合冷媒迴路的構成，包含：所謂的再熱除溼運轉、以及冷房除溼運轉。The dehumidification operation is matched with the configuration of the refrigerant circuit, including the so-called reheat dehumidification operation and the cold room dehumidification operation.

於圖3，也揭示出可以再熱除溼之冷媒迴路構成，在圖3中，室內熱交換器12分成第1室內熱交換器12a以及第2室內熱交換器12b，在以V所示的位置設有連接這些的室內膨脹閥。而且，在圖3表示之例，第2室內熱交換器12b位置在第1室內熱交換器12a的上側。在進行上述的通常的冷房運轉或是暖房運轉之際，控制室內膨脹閥V為全開，而且，適宜調整室外膨脹閥34的開啟度。In Fig. 3, the structure of a refrigerant circuit capable of reheating and dehumidifying is also disclosed. In Fig. 3, the indoor heat exchanger 12 is divided into a first indoor heat exchanger 12a and a second indoor heat exchanger 12b. There is an indoor expansion valve connecting these. In the example shown in FIG. 3, the second indoor heat exchanger 12b is positioned above the first indoor heat exchanger 12a. When performing the above-mentioned normal cooling operation or heating operation, the indoor expansion valve V is controlled to be fully opened, and the opening degree of the outdoor expansion valve 34 is appropriately adjusted.

在再熱除溼運轉中，控制部K係控制四通閥35，讓室外熱交換器32及第1室內熱交換器12a作為凝結器發揮功能，讓第2室內熱交換器12b作為蒸發器發揮功能。更進一步，控制部K係將室外膨脹閥34全開，把連接第1室內熱交換器12a與第2室內熱交換器12b之室內膨脹閥V設成規定開啟度。接著，控制部K驅動壓縮機31與室內風扇14。藉此，用蒸發器也就是第2室內熱交換器12b進行了熱交換的低溫的空氣，被凝結器也就是第1室內熱交換器12a適度加熱，來對室內(被空調空間)除溼。在再熱除溼運轉中，室內熱交換器12的一部分作為蒸發器發揮作用的緣故，室內熱交換器12的一部分浸溼，室內機的內部成為高溼度狀態。During the reheating and dehumidification operation, the control unit K controls the four-way valve 35 so that the outdoor heat exchanger 32 and the first indoor heat exchanger 12a function as condensers, and the second indoor heat exchanger 12b functions as an evaporator Features. Furthermore, the control unit K fully opens the outdoor expansion valve 34, and sets the indoor expansion valve V connecting the first indoor heat exchanger 12a and the second indoor heat exchanger 12b to a predetermined opening degree. Next, the control unit K drives the compressor 31 and the indoor fan 14. Thereby, the low-temperature air heat-exchanged by the evaporator, that is, the second indoor heat exchanger 12b, is appropriately heated by the condenser, that is, the first indoor heat exchanger 12a, to dehumidify the room (air-conditioned space). During the reheating and dehumidification operation, since a part of the indoor heat exchanger 12 functions as an evaporator, a part of the indoor heat exchanger 12 is wetted, and the interior of the indoor unit becomes a high humidity state.

在冷房除溼運轉中，控制部K係比起上述的冷房運轉的情況以更低頻率運轉壓縮機31並且降低室內風扇14的轉速，進行低能力的冷房運轉，藉此，一方面抑制室內溫度的下降一方面使溼度下降。在冷房除溼運轉中，是抑制在低頻率，與冷房運轉同樣，室內熱交換器12作為蒸發器發揮作用的緣故，室內熱交換器12浸溼，室內機的內部成為高溼度狀態。In the cold room dehumidification operation, the control unit K operates the compressor 31 at a lower frequency than the above-mentioned cold room operation and reduces the rotation speed of the indoor fan 14 to perform a low-power cold room operation, thereby suppressing the indoor temperature on the one hand. On the one hand, the drop in the humidity reduces the humidity. In the cold room dehumidification operation, the frequency is suppressed to be low. As in the cold room operation, because the indoor heat exchanger 12 functions as an evaporator, the indoor heat exchanger 12 gets wet and the interior of the indoor unit becomes a high humidity state.

在送風運轉中，控制部K不驅動壓縮機31，而驅動室內風扇14，藉此，使從空氣吸入口h1等取入的室內空氣，通過室內熱交換器12，從把上下風向板19控制成開狀態的空氣吹出口h3吹出。In the air blowing operation, the control unit K does not drive the compressor 31, but drives the indoor fan 14, thereby causing the indoor air taken in from the air suction port h1 to pass through the indoor heat exchanger 12, and to control the upper and lower wind direction plates 19 The open air blowing port h3 blows out.

在以上述的室內熱交換器12的至少一部分來冷卻空氣的運轉時(冷房運轉、除溼運轉)，室內熱交換器12結露，室內機的內部成為高溼度狀態。而且，在該狀態下停止運轉後，因為殘留在室內機10內部的結露水，是有持續高溼度狀態的可能性。接著，持續高溼度狀態的話，是有在室內機10的內部繁殖黴菌的可能性，不衛生。在冷房運轉或除溼運轉結束後，檢測到滿足規定的溫溼度條件的時間為24小時以下的短的時間(例如7小時以上未達14小時)，進行使室內機內部乾燥的運轉之技術是廣為人知。但是，正是因為室內的溫度或溼度為高的環境，所以利用者使用冷房運轉或除溼運轉，即便在運轉停止中，在這樣的環境下更進一步頻繁進行加熱室內的乾燥運轉的話，是有給利用者不舒適感之虞，更進一步，也有讓空調機100故障之虞。During the operation (cold room operation, dehumidification operation) for cooling the air with at least a part of the indoor heat exchanger 12 described above, condensation occurs in the indoor heat exchanger 12, and the interior of the indoor unit becomes a high humidity state. Moreover, after the operation is stopped in this state, there is a possibility that the high humidity state may continue due to the dew condensation water remaining inside the indoor unit 10. Next, if the high humidity state continues, there is a possibility that mold may grow inside the indoor unit 10, which is unhygienic. After the cooling operation or dehumidification operation is completed, it is detected that the time required to meet the specified temperature and humidity conditions is 24 hours or less (for example, 7 hours or more and less than 14 hours), and the technology to perform the operation to dry the interior of the indoor unit is Well known. However, it is precisely because the indoor temperature or humidity is an environment that the user uses the cooling operation or dehumidification operation, even if the operation is stopped, in such an environment, if the drying operation in the heating room is performed more frequently, it is helpful The user may feel uncomfortable, and furthermore, the air conditioner 100 may malfunction.

在此，本實施方式中的空調機100係構成如下：經常性(至少空調運轉停止中，較佳為空調運轉中及空調運轉停止中)至少監視空氣的溼度(較佳為溼度及溫度)，對於在運轉中及停止中溼度(較佳為溫度及溼度)滿足規定條件之累計期間超過了規定時間進行回應，執行使室內機內部乾燥的乾燥運轉。在此，判斷是否乾燥運轉的規定時間，為超過24小時且在192小時以下的範圍內的值，較佳為120小時以上192小時以下的範圍內的值，更佳為168小時(7日)。構成空調機100在從溼度(較佳為溫度及溼度)滿足了規定條件的累計期間超過了規定時間開始進行讓室內機內部成為低溼狀態之乾燥運轉，經此，可以一方面合適地抑制黴菌的繁殖，一方面減低給利用者的不舒適感。Here, the air conditioner 100 in this embodiment is configured as follows: constantly (at least while the air-conditioning operation is stopped, preferably while the air-conditioning operation and when the air-conditioning operation is stopped) at least monitors the humidity (preferably humidity and temperature) of the air, Responding to a response that the cumulative period of humidity (preferably temperature and humidity) meeting the specified conditions exceeds the specified time during operation and stopping, and executes a dry operation to dry the interior of the indoor unit. Here, the predetermined time for judging whether or not the drying operation is a value in the range of more than 24 hours and 192 hours or less, preferably a value in the range of 120 hours to 192 hours, and more preferably 168 hours (7 days) . The air conditioner 100 is configured to perform a drying operation to make the interior of the indoor unit into a low-humidity state after the cumulative period of the humidity (preferably temperature and humidity) meeting the prescribed conditions exceeds the prescribed time. This can appropriately suppress mold on the one hand. On the one hand, it reduces the discomfort to users.

以下，參閱圖5~圖8，更詳細說明有關本實施方式所致之空調機100所執行之實現一邊監視溼度及溫度一邊實施乾燥運轉的功能之控制。Hereinafter, referring to FIGS. 5 to 8, a more detailed description will be given of the control performed by the air conditioner 100 according to the present embodiment to realize the function of implementing the drying operation while monitoring the humidity and temperature.

圖5為表示本發明的實施方式所致之空調機所執行的溫溼度監視控制之流程圖。尚且，說明圖5表示的控制，是作為控制部K所執行的。尚且，說明在圖5表示控制中，監視溼度及溫度之兩方的實施方式。Fig. 5 is a flowchart showing the temperature and humidity monitoring control performed by the air conditioner according to the embodiment of the present invention. Furthermore, it is explained that the control shown in FIG. 5 is executed as the control unit K. Furthermore, an embodiment in which both humidity and temperature are monitored in the control shown in FIG. 5 will be described.

空調機100被供電的話，首先轉移到停止狀態，對來自遙控器40的運轉指令進行回應，開始規定的運轉狀態(例如，前次設定的運轉狀態)下的運轉。而且，空調機100係對來自遙控器40的停止指令進行回應，再次轉移到停止狀態。空調機100係更進一步對來自遙控器40的運轉狀態的變更指令進行回應，切換運轉狀態。而且，在冷房運轉或除溼運轉的運轉中，室內溫度到達了設定溫度的情況等，停止(熱關機(thermo-off))壓縮機，轉移到與送風運轉同樣的運轉狀態。而且，空調機100也實施在例如冷房、暖房、除溼運轉等的累計時間超過了規定值的情況下，在停止的情況下進行自動過濾器掃除運轉，或是在計時器或攝像部23檢測到人不在的情況下進行結凍清洗等之其他的維修運轉。尚且，以下說明之一邊監視溼度及溼度一邊實施乾燥運轉的功能，也是維修運轉的一種。說明圖5表示的控制係與這些通常的控制及其他的維修運轉並行且在背景執行。When the air conditioner 100 is supplied with power, it first transitions to a stop state, responds to an operation command from the remote controller 40, and starts operation in a predetermined operation state (for example, the operation state set last time). Furthermore, the air conditioner 100 responds to the stop command from the remote controller 40, and transits to the stop state again. The air conditioner 100 further responds to the operation state change command from the remote controller 40 to switch the operation state. In addition, during cooling operation or dehumidification operation, if the indoor temperature reaches the set temperature, etc., the compressor is stopped (thermo-off), and the operation state is the same as that of the air blowing operation. In addition, the air conditioner 100 also implements automatic filter cleaning operation when the cumulative time of cooling, heating, dehumidification operation, etc. exceeds a predetermined value, or the timer or imaging unit 23 detects when it stops. Carry out other maintenance operations, such as freezing and washing, in the absence of people. In addition, one of the functions described below, which monitors humidity and humidity while performing a dry operation, is also a type of maintenance operation. It is explained that the control system shown in FIG. 5 is executed in the background in parallel with these normal controls and other maintenance operations.

圖5表示的控制，係對空調機100已被供電進行回應，從步驟S100開始。在步驟S101，控制部K判定空調機100是否處於停止狀態。在步驟S101，在判定了空調機100處於停止狀態的情況(YES)下，控制分歧往步驟S102。The control shown in FIG. 5 responds to that the air conditioner 100 has been supplied with power, and starts from step S100. In step S101, the control unit K determines whether the air conditioner 100 is in a stopped state. In step S101, when it is determined that the air conditioner 100 is in the stopped state (YES), the control branches to step S102.

在步驟S102，控制部K係利用溼度感測器24b及室內溫度感測器24a，分別檢測室內機10的內部的溼度及溫度，取得現在的溼度及溫度的值。In step S102, the control unit K uses the humidity sensor 24b and the indoor temperature sensor 24a to detect the humidity and temperature inside the indoor unit 10, respectively, and obtain the current humidity and temperature values.

溼度感測器24b及室內溫度感測器24a係本來是構成，在通常運轉時，檢測經由室內風扇14的旋轉所取入的空氣亦即室內(被空調空間)的空氣之溼度及溫度。在此，是取得室內機10的內部的溼度及溫度為目的的緣故，特別是在不驅動室內風扇馬達14a，停止了室內風扇14的旋轉的狀態下，藉由溼度感測器24b及室內溫度感測器24a來檢測溼度及溫度。The humidity sensor 24b and the indoor temperature sensor 24a are originally constructed, and, during normal operation, they detect the humidity and temperature of the air taken in through the rotation of the indoor fan 14, that is, the air in the room (air-conditioned space). Here, for the purpose of obtaining the humidity and temperature inside the indoor unit 10, especially when the indoor fan motor 14a is not driven and the rotation of the indoor fan 14 is stopped, the humidity sensor 24b and the indoor temperature The sensor 24a detects humidity and temperature.

尚且，在本實施方式中，為了監視溫度及溼度之兩者，利用室內溫度感測器24a也檢測室內機10的內部的溫度。希望除了溼度也監視溫度，但是，在不監視溫度之其他的實施方式下，也可以僅取得溼度感測器24b所致之溼度。Furthermore, in this embodiment, in order to monitor both temperature and humidity, the temperature inside the indoor unit 10 is also detected by the indoor temperature sensor 24a. It is desirable to monitor the temperature in addition to the humidity. However, in other embodiments that do not monitor the temperature, only the humidity caused by the humidity sensor 24b may be obtained.

在步驟S103，控制部K判定利用溼度感測器24b檢測出的溼度及利用室內溫度感測器24a檢測出的溫度是否滿足規定條件。在此，作為規定條件，可以使用溼度為65%以上之溼度的閾值條件等，可以使用溫度為10℃以上35℃以下之溫度的閾值條件等。在步驟S103，在判定出溼度及溫度不滿足規定條件的情況(NO)下，在適宜經過規定的待機時間後，控制回到步驟S101。另一方面，在步驟S103，在判定出溼度及溫度滿足規定條件的情況(YES)下，控制前進到步驟S105。In step S103, the control unit K determines whether the humidity detected by the humidity sensor 24b and the temperature detected by the indoor temperature sensor 24a satisfy predetermined conditions. Here, as the predetermined conditions, a humidity threshold condition of 65% or more can be used, and a temperature threshold condition of 10°C or more and 35°C or less can be used. In step S103, when it is determined that the humidity and temperature do not satisfy the predetermined conditions (NO), after a predetermined waiting time has passed as appropriate, the control returns to step S101. On the other hand, in step S103, when it is determined that the humidity and temperature satisfy the predetermined conditions (YES), the control proceeds to step S105.

在此，再次參閱步驟S101。在步驟S101，在判定出不為停止狀態的情況(NO)下，控制往步驟S104分歧。在步驟S104，控制部K係對運轉狀態為暖房運轉、冷房運轉、除溼運轉、或是送風運轉進行配合，分歧控制。Here, refer to step S101 again. In step S101, when it is determined that it is not in the stopped state (NO), the control branches to step S104. In step S104, the control unit K performs branch control for the operation status of heating operation, cooling operation, dehumidification operation, or air supply operation.

在步驟S104，在判定出運轉狀態為暖房運轉的情況(暖房)下，在適宜經過待機時間後，控制回到步驟S101。使用室內熱交換器12整體加熱空氣的運轉狀態，例如處於暖房運轉的運轉時間期望讓室內機10內部處於低溼狀態的緣故，作為溼度及溫度不滿足規定條件，相關的運轉時間，係從後述的溼度及溫度滿足了規定條件之累計期間來予以排除。處於暖房運轉中的熱關機狀態的情況也是同樣。In step S104, when it is determined that the operating state is the heating operation (heating), after the standby time has elapsed appropriately, the control returns to step S101. The operating state where the indoor heat exchanger 12 is used to heat the air as a whole. For example, the operating time during the heating operation is expected to keep the interior of the indoor unit 10 in a low-humidity state. As the humidity and temperature do not meet the specified conditions, the related operating time will be described later The humidity and temperature meet the specified conditions for the cumulative period to be excluded. The same applies to the thermal shutdown state during heating operation.

在步驟S104，在被判定出運轉狀態為冷房運轉及除溼運轉中任意一個的情況(冷房/除溼)下，前進往步驟S105的直接控制。步驟S105乃是分歧在步驟S103溼度及溫度滿足規定條件的情況下的處理。此乃是，在至少部分使用冷房運轉或除溼運轉等的室內熱交換器12來冷卻空氣的運轉狀態下，室內熱交換器12至少部分結露，室內機10內部處於高溼度狀態的緣故。該情況下，作為溼度及溫度滿足了規定條件，相關的運轉時間被算入到滿足後述的規定條件的累積期間。冷房運轉中，即便處於熱關機狀態，也是有結露的可能性，所以該時間也被算入到累積期間。In step S104, when it is determined that the operating state is either the cooling operation or the dehumidification operation (cooling/dehumidifying), the process proceeds to the direct control of step S105. Step S105 is processing when the humidity and temperature meet the predetermined conditions in step S103. This is because the indoor heat exchanger 12 is at least partially dew condensed and the interior of the indoor unit 10 is in a high humidity state in an operating state where the indoor heat exchanger 12, such as a cooling operation or a dehumidification operation, is used to cool air at least partially. In this case, it is assumed that the humidity and temperature satisfy the predetermined conditions, and the relevant operating time is included in the accumulation period that satisfies the predetermined conditions described later. During cooling operation, even in the thermal shutdown state, there is a possibility of condensation, so this time is also included in the accumulation period.

在步驟S104，在判定出運轉狀態為送風運轉的情況(送風)下，控制前進到步驟S102。該情況下，在步驟S103，控制部K係利用溼度感測器24b及室內溫度感測器24a檢測溼度及溫度，取得溼度及溫度的值。In step S104, when it is determined that the operating state is the air blowing operation (air blowing), the control proceeds to step S102. In this case, in step S103, the control unit K detects the humidity and temperature using the humidity sensor 24b and the room temperature sensor 24a, and obtains the values of the humidity and temperature.

如上述，在此，其目的在於取得室內機10的內部的溼度及溫度，但是，送風運轉時，不進行冷房及暖房等，考慮到室內機內部的溫度及溼度與房間的溫度及溼度為同等。為此，步驟S104中，控制部K係一邊驅動室內風扇14，一邊藉由溼度感測器24b及室內溫度感測器24a檢測溼度及溫度。As mentioned above, here, the purpose is to obtain the internal humidity and temperature of the indoor unit 10. However, during the air supply operation, cooling and heating are not performed. Considering that the internal temperature and humidity of the indoor unit are equivalent to the room temperature and humidity. . For this reason, in step S104, the control unit K drives the indoor fan 14 while detecting the humidity and temperature through the humidity sensor 24b and the indoor temperature sensor 24a.

在步驟S105，控制部K係累計溼度及溫度滿足規定條件的時間，得到累計期間。累計期間係例如在室內控制電路25的記憶部25a設有累計部25c，並保持在累計部25c。控制部K係在溼度及溫度滿足了規定條件的情況下，僅規定的值加到累計部25c現在保持的值。作為累計時間的累計方法並沒有特別限定，但是，可以對現在的值僅加上每被1次判定出溼度及溫度滿足規定條件之監視的時間間隔(上述的規定的待機時間)份，也可以在連續判定出溼度及溫度滿足了規定條件的情況下，把前次與此次的時間的差值予以相加。尚且，也在溼度及溫度暫時性不滿足規定條件(例如低溼狀態)情況下，不重置累計部25c的值，在溼度及溫度再次滿足規定條件的時點下，恢復累計。此乃是，考慮到即便一度未符合條件而黴菌停止成長，但是溼度及溫度再次變高的話，黴菌恢復成長的緣故。In step S105, the control unit K accumulates the time during which the humidity and temperature meet the predetermined conditions, and obtains the accumulation period. For example, the accumulation period is provided with an accumulation unit 25c in the memory unit 25a of the indoor control circuit 25, and is held in the accumulation unit 25c. When the humidity and temperature meet the predetermined conditions, the control unit K adds only the predetermined value to the value currently held by the integration unit 25c. The method of accumulating the accumulated time is not particularly limited, but it is possible to add to the current value only the time interval (the above-mentioned predetermined standby time) of the monitoring every time it is determined that the humidity and temperature meet the predetermined conditions. When it is continuously determined that the humidity and temperature meet the prescribed conditions, the difference between the previous time and the current time is added. Furthermore, even when the humidity and temperature temporarily do not meet the predetermined conditions (for example, low humidity), the value of the integration unit 25c is not reset, and the integration is restored when the humidity and temperature meet the predetermined conditions again. This is because even if the conditions are not met and the mold stops growing, if the humidity and temperature increase again, the mold will resume growth.

此時，在溼度及溫度滿足規定條件的情況下，可以僅累計滿足的時間份(作為10分鐘的監視的時間間隔，在該時序下溼度及溫度滿足規定條件的話，加上10分鐘之情況下的10分鐘)。但是，在較合適方面，根據具體的溼度或溫度，黴菌繁殖的難易為不同的緣故，可以根據檢測出的溼度及溫度補正累計的時間。在特定的實施方式下，除了對滿足的時間之保持原樣的值進行加法運算之外，也可以把對滿足的時間乘上了規定的補正係數後的值，加到累計部25c現在保持的值。At this time, when the humidity and temperature meet the specified conditions, you can only accumulate the time that is satisfied (as a 10-minute monitoring time interval, if the humidity and temperature meet the specified conditions at this time sequence, add 10 minutes) 10 minutes). However, in terms of more appropriateness, depending on the specific humidity or temperature, the difficulty of mold growth is different, and the accumulated time can be corrected based on the detected humidity and temperature. In a specific embodiment, in addition to adding the value of the satisfied time as it is, it is also possible to add the value obtained by multiplying the satisfied time by a predetermined correction coefficient to the value currently held by the accumulating unit 25c. .

圖6為表示把經由本發明的實施方式所致之空調機參閱到的時間累計時的補正係數予以保持之表格的資料構造。如圖6表示，補正係數表格乃是表現出溼度的各範圍(例如80~90%係表示80%以上未達90%。)作為行，溫度的各範圍(例如25~30℃係表示25℃以上未達30℃。)作為列之矩陣。6 is a diagram showing the data structure of a table that holds the correction coefficient when the time referenced by the air conditioner according to the embodiment of the present invention is accumulated. As shown in Figure 6, the correction coefficient table shows each range of humidity (for example, 80~90% means 80% or more and less than 90%.) As a row, each range of temperature (for example, 25~30°C means 25°C) The above does not reach 30°C.) As a matrix of columns.

如圖6例示，把溼度為90%以上100%以下且溫度為25℃以上未達30℃的領域作為基準也就是最大值1，輸入從0到1為止的值。如圖6例示，溫度為低的領域(在例示為未達10℃)及溫度為高的領域(在例示為40℃以上)下補正係數為0。而且，溼度為低的領域(在例示為未達60%)下補正係數為0，但是，該範圍的情況係通常在步驟S103不滿足規定條件。As shown in Fig. 6, the area where the humidity is 90% or more and 100% or less and the temperature is 25°C or more and less than 30°C is used as the reference, which is the maximum value 1, and enter the value from 0 to 1. As shown in FIG. 6, the correction coefficient is 0 in the area where the temperature is low (in the example below 10° C.) and the area where the temperature is high (in the example, 40° C. or more). In addition, the correction coefficient is 0 in a region where the humidity is low (not as high as 60% in the example). However, in the case of this range, the predetermined condition is usually not satisfied in step S103.

再次參閱圖5。在步驟S106，控制部K係判定在運轉中及停止中，溼度及溫度滿足了規定條件的累計期間是否超過了閾值(規定時間)。在此，閾值(規定時間)為超過24小時(1日)且在192小時(8日)以下的範圍內的值，較佳為120小時(5日)以上192小時(8日)以下的範圍內的值，更佳為168小時(7日)。在此，作為閾值的規定時間的範圍係以溼度90%~100%且溫度25℃~29℃作為基準(補正係數1)的情況下的值。Refer to Figure 5 again. In step S106, the control unit K determines whether the cumulative period during which the humidity and temperature meet the predetermined conditions exceeds the threshold value (the predetermined time) during operation and stop. Here, the threshold value (predetermined time) is a value exceeding 24 hours (1 day) and within a range of 192 hours (8 days) or less, preferably within a range of 120 hours (5 days) to 192 hours (8 days). The value within is more preferably 168 hours (7 days). Here, the range of the predetermined time as the threshold value is a value when the humidity is 90% to 100% and the temperature is 25°C to 29°C as a reference (correction coefficient 1).

在步驟S106，在判定出累計期間尚未超過閾值(規定時間)的情況(NO)下，在適宜經過規定的待機時間後，控制回到步驟S101，持續溼度的監視。另一方面，在步驟S106，在判定出累計期間超過了閾值(規定時間)的情況(YES)下，控制前進到步驟S107。In step S106, when it is determined that the accumulation period has not exceeded the threshold value (predetermined time) (NO), after the predetermined standby time has passed appropriately, the control returns to step S101 and the humidity monitoring is continued. On the other hand, in step S106, when it is determined that the accumulation period exceeds the threshold value (predetermined time) (YES), the control proceeds to step S107.

在步驟S107，控制部K係更進一步判定是否滿足實施條件。在此，實施條件係包含溼度及溫度是否處於規定範圍的條件。In step S107, the control unit K further determines whether the implementation conditions are satisfied. Here, the implementation conditions include conditions for whether humidity and temperature are within a predetermined range.

圖7為說明本發明的實施方式所致之空調機執行乾燥運轉的條件之圖。如圖7表示，以溼度的規定範圍(A~B)及溫度的規定範圍(C~D)之兩者特定出的範圍定義作為實施乾燥運轉的範圍。該範圍係例如考慮到藉由進行乾燥運轉可以抑制黴菌的優點以及給利用者不舒適感的缺點而定出。例如，在白天的室內處於高溫多溼的狀態時進行讓室內暖和的乾燥運轉的話，會給利用者不舒適感的缺點這一方會比較大，是可以從實施乾燥運轉的範圍來排除。在實施乾燥運轉的範圍外的情況下，暫時展延乾燥運轉的實施，例如在夜晚的室內溫度比較下降的時序下，當滿足實施條件，實施乾燥運轉。尚且，也可以把實施圖7表示的乾燥運轉的範圍，作為進行累計的範圍。Fig. 7 is a diagram illustrating conditions under which the air conditioner performs the drying operation according to the embodiment of the present invention. As shown in Fig. 7, the range specified by both the specified range of humidity (A~B) and the specified range of temperature (C~D) is defined as the range in which the drying operation is performed. This range is determined, for example, in consideration of the advantages of suppressing molds by performing a drying operation and the disadvantages of uncomfortable feeling to the user. For example, if a drying operation to warm the room is performed during the day when the room is at a high temperature and high humidity, the disadvantage of giving the user a sense of discomfort is relatively large, which can be excluded from the scope of the drying operation. When the drying operation is outside the scope of the drying operation, the execution of the drying operation is temporarily extended. For example, at a time sequence when the room temperature at night is relatively lowered, the drying operation is executed when the execution conditions are met. Furthermore, the range in which the drying operation shown in FIG. 7 is implemented may be the range in which the integration is performed.

而且，在冷房運轉或除溼運轉下的運轉中，在這期間加入讓室內暖和的乾燥運轉的話，會給利用者不舒適感的可能性大的緣故，較佳為在冷房運轉或除溼運轉下的運轉中不進行乾燥運轉。在冷房運轉或除溼運轉下的運轉中，在累計時間超過了閾值的情況下，可以在該運轉停止後進行。In addition, during cooling operation or dehumidification operation, if a dry operation to warm the room is added during this period, the user may feel uncomfortable. Therefore, cooling operation or dehumidification operation is preferred. The drying operation is not performed during the next operation. In the operation under cooling operation or dehumidification operation, if the accumulated time exceeds the threshold value, the operation can be performed after the operation is stopped.

在步驟S107，在判定出尚未滿足實施條件的情況(NO)下，在適宜經過規定的待機時間後，控制回到步驟S101。另一方面，在步驟S107，在判定出滿足實施條件的情況(YES)下，控制前進到步驟S108。In step S107, when it is determined that the implementation conditions have not been satisfied (NO), after a predetermined waiting time has passed appropriately, the control returns to step S101. On the other hand, in step S107, when it is determined that the execution condition is satisfied (YES), the control proceeds to step S108.

在步驟S108，控制部K係使具有室內熱交換器12的冷媒迴路Q動作，執行使室內機10的內部乾燥的乾燥運轉。乾燥運轉可以是以暖房運轉、送風運轉或是這些的組合來實現。在送風運轉也可以達成低溼狀態，但是，暖房運轉的這一方可以更迅速達成低溼狀態的緣故，較佳為在乾燥運轉也包含暖房運轉。而且，在其他的實施方式下，可以反覆進行送風運轉及暖房運轉。In step S108, the control unit K operates the refrigerant circuit Q having the indoor heat exchanger 12 to perform a drying operation for drying the interior of the indoor unit 10. Drying operation can be realized by heating operation, air supply operation or a combination of these. A low-humidity state can also be achieved in the air blowing operation, but because the heating operation can achieve a low-humidity state more quickly, it is preferable that the drying operation also includes the heating operation. Furthermore, in other embodiments, the air blowing operation and the room heating operation may be repeatedly performed.

在乾燥運轉中的暖房運轉之際，控制部K係切換四通閥35使室內熱交換器12作為凝結器發揮作用、使室外熱交換器32作為蒸發器發揮作用，並驅動壓縮機31。控制部K雖然沒有特別限定，較佳為可以在乾燥運轉之際，設定比通常運轉中的最低值還低的壓縮機轉速及室內風扇轉速。而且，較佳為，控制部K係在把上下風向板19相對於風的吹出方向比起通常運轉時的情況下更直立的狀態(比起通常更把上下風向板19的角度朝上)下，執行乾燥運轉。以比通常還低的轉速來驅動室內風扇14，而且，使上下風向板19接近閉狀態的狀態下，進行暖房運轉，經此，被加熱的空氣盡可能不漏出到室內(被空調空間)，所以，可以有效率乾燥室內機10內部。經此，盡可能不會給利用者不舒適感，並且可以進行室內機10的內部的乾燥。During the heating operation during the drying operation, the control unit K switches the four-way valve 35 so that the indoor heat exchanger 12 functions as a condenser and the outdoor heat exchanger 32 functions as an evaporator, and drives the compressor 31. Although the control unit K is not particularly limited, it is preferable to set the compressor rotation speed and the indoor fan rotation speed lower than the minimum value in the normal operation during the dry operation. Furthermore, it is preferable that the control section K is in a state where the up-and-down wind direction plate 19 with respect to the blowing direction of the wind is more upright than in the case of normal operation (the angle of the up-and-down wind direction plate 19 is turned upward than usual). , Perform dry operation. The indoor fan 14 is driven at a rotation speed lower than usual, and the heating operation is performed with the upper and lower wind direction plates 19 close to the closed state, so that the heated air does not leak into the room (air-conditioned space) as much as possible. Therefore, the inside of the indoor unit 10 can be efficiently dried. With this, it is possible to dry the interior of the indoor unit 10 without giving the user a sense of discomfort as much as possible.

在步驟S109，控制部K係對乾燥運轉已經完畢進行回應，重置累計部25c，在適宜經過規定的待機時間後，控制回到步驟S101。亦即，被保持在累計部25c的累計時間，為從初次啟動時起算的累計時間，或是從前次的乾燥運轉實施時起算的累積時間。In step S109, the control unit K responds to the completion of the drying operation, resets the accumulation unit 25c, and after a predetermined waiting time has passed as appropriate, the control returns to step S101. That is, the accumulated time held in the accumulation unit 25c is the accumulated time calculated from the time of initial startup or the accumulated time calculated from the execution of the previous drying operation.

圖8為示意性說明黴菌的生命週期之圖。黴菌係浮游在空氣，著床於新的場所。該胞子發芽，一邊細胞***，一邊使菌絲生長。接著，菌絲伸長成熟的話，形成新的胞子，使胞子飛散在空氣中。這樣的生命週期中，從胞子著床到使胞子飛散為止的期間在黴菌容易繁殖的條件下大約是7日這一點是廣為人知。為了盡量不讓菌絲生長，在早期進行(例如在黴菌容易繁殖的高溫多溼條件下7小時以上未達14小時的程度)乾燥運轉來圖求黴菌的成長的抑制，經此，是有可以抑制在目視級別下的黴菌的成長的可能性。但是，太頻繁進行乾燥運轉的話，會給利用者不舒適感，更進一步，很可能會給利用者抱持著故障的疑念。另一方面，黴菌係藉由胞子的飛散大量繁殖。Fig. 8 is a diagram schematically illustrating the life cycle of molds. The mold floats in the air and implants in a new place. The spores germinate, and the hyphae grow while the cells divide. Then, when the hyphae grow and mature, new spores are formed and the spores fly into the air. In such a life cycle, it is widely known that the period from implantation of the spores to the scattering of the spores is approximately 7 days under conditions where molds can easily multiply. In order to prevent the growth of mycelium as much as possible, it is possible to perform drying operation at an early stage (for example, under the conditions of high temperature and humidity where mold is easy to multiply, for more than 7 hours but less than 14 hours) to suppress the growth of mold. Suppresses the possibility of mold growth at the visual level. However, if the drying operation is performed too frequently, the user will feel uncomfortable, and furthermore, the user may be suspicious of malfunction. On the other hand, molds multiply by the scattering of spores.

在此，在本實施方式下，係構成如下：考慮到上述之從胞子著床到使胞子飛散為止的期間，對至少在空調運轉停止中溼度(較佳為溼度及溫度)滿足了規定條件的累計期間超過了規定時間也就是超過24小時且在192小時以下的範圍內的值進行回應，執行使室內機內部乾燥的乾燥運轉。規定時間較佳為120小時以上192小時以下的範圍內的值，更佳為168小時(7日)。在發生胞子的飛散之前，以構成實施乾燥運轉的方式，可以一邊合適地抑制黴菌的繁殖，一邊減低給利用者的不舒適感。Here, in this embodiment, the system is configured as follows: Considering the period from the implantation of the spores to the scattering of the spores, at least the humidity (preferably humidity and temperature) satisfies the predetermined conditions during the stop of the air-conditioning operation. The accumulation period exceeds the predetermined time, that is, exceeds 24 hours and responds to a value within the range of 192 hours or less, and executes a drying operation to dry the interior of the indoor unit. The predetermined time is preferably a value in the range of 120 hours or more and 192 hours or less, and more preferably 168 hours (7 days). Before the scattering of spores occurs, it is configured to implement a drying operation, which can appropriately suppress the growth of molds while reducing the discomfort to the user.

尚且，本實施方式所致之乾燥運轉係可以與使上述的OH- 、OH自由基、臭氧等的除菌物質充滿在室內的除菌運轉組合進行。從抑制黴菌的觀點來看，使用臭氧作為除菌物質為佳。與除菌運轉組合的情況下，較佳為，乾燥運轉係以比在室內機內部放出除菌物質的除菌運轉的頻度還要低頻度來實施。亦即，以高的頻度的循環進行定期在室內機內部放出除菌物質的除菌運轉來一邊抑制黴菌的生長，以比較低的頻度的循環進行乾燥運轉來抑制黴菌為佳。經此，可以減輕給利用者不舒適感，且更進一步抑制黴菌。Furthermore, the drying operation according to the present embodiment can be performed in combination with the sterilization operation in which the above-mentioned OH − , OH radical, ozone, and other sterilization substances are filled in the room. From the standpoint of inhibiting mold, it is better to use ozone as a sterilizing substance. When combined with the sterilization operation, it is preferable that the drying operation be performed at a lower frequency than the frequency of the sterilization operation in which the sterilization material is released inside the indoor unit. That is, it is preferable to perform a sterilization operation that periodically releases the sterilizing material inside the indoor unit in a high-frequency cycle to suppress the growth of mold, and it is preferable to perform a drying operation in a relatively low-frequency cycle to suppress the mold. Through this, the discomfort to the user can be reduced, and the mold can be further suppressed.

如以上說明，根據上述的實施方式，可以提供一種空調機，其係可以抑制在室內機內部的黴菌的繁殖並且減低給利用者的不舒適感。As explained above, according to the above-mentioned embodiment, it is possible to provide an air conditioner which can suppress the growth of mold inside the indoor unit and reduce the discomfort to the user.
