空調機air conditioner

本發明是關於一種空調機。 The invention relates to an air conditioner.

就使空調機的室內熱交換器成為清潔的狀態來說，例如專利文獻1，有針對「具備暖房運轉後讓水附著在前述鰭片表面的水分賦予手段」的空調機進行記載。此外，前述的水賦予手段，是藉由暖房運轉後進行的冷房運轉，讓水附著在室內熱交換器的鰭片表面。 In order to keep the indoor heat exchanger of the air conditioner clean, for example, Patent Document 1 describes an air conditioner having a "water-supplying means for allowing water to adhere to the surface of the fins after a greenhouse operation". In addition, the aforementioned means for applying water is to allow water to adhere to the surface of the fins of the indoor heat exchanger through a cold room operation performed after the warm room operation.

〔先前技術文獻〕 [Previous Technical Literature] 〔專利文獻〕 [Patent Literature]

[專利文獻1]日本特許第4931566號公報 [Patent Document 1] Japanese Patent No. 4931566

然而，專利文獻1並沒有針對取消水分賦予手段的處理的功能進行記載。此外，在水分賦予手段的處理中會有空調機的驅動音產生或朝室內吹出冷風的可能性。因此，期望能迴避水分賦予手段所致的處理違反使用者的旨意進行的情況。 However, Patent Document 1 does not describe a function of canceling the processing of the moisture applying means. In addition, there is a possibility that the driving sound of the air conditioner is generated or the cold air is blown into the room during the treatment of the moisture applying means. Therefore, it is desirable to avoid the case where the processing by the moisture application means is performed against the user's intention.

於此，本發明，是以提供可取消室內熱交換器的洗淨的空調機作為課題。 Here, the present invention has as its object to provide an air conditioner capable of eliminating washing of an indoor heat exchanger.

為了解決前述課題，本發明之特徵，是通知手段，是在開始室內熱交換器的凍結的處理之前，進行執行前述處理的內容的通知，控制手段，是從開始前述通知手段所致的前述通知到經過預定時間，從遙控器或可攜式終端機接收到預定的取消指令時，不進行前述處理的開始。 In order to solve the aforementioned problem, the present invention is characterized in that the notification means is a notification that executes the content of the processing before the freezing process of the indoor heat exchanger is started, and the control means is the notification that is caused by starting the notification means When a predetermined time has elapsed and a predetermined cancellation instruction is received from the remote controller or the portable terminal, the aforementioned process is not started.

又，本發明之特徵，是控制手段從開始前述室內熱交換器的凍結的處理到經過預定時間之後，從遙控器或可攜式終端機接收到前述處理的取消指令的時候，進行前述室內熱交換器的乾燥，前述乾燥，是藉由將空氣送入前述室內熱交換器的室內風扇的驅動來進行。 In addition, the present invention is characterized in that the control means performs the indoor heat when a cancellation instruction for the process is received from a remote control or a portable terminal after a predetermined time has elapsed from the start of the freezing process of the indoor heat exchanger. The drying of the exchanger and the drying are performed by driving an indoor fan that sends air into the indoor heat exchanger.

此外，室內熱交換器的凍結等(洗淨)的「取消」，除了進行凍結等之前的取消之外，也包含進行凍結等的時候的取消(中止)。 In addition, the "cancellation" of freezing and the like (washing) of the indoor heat exchanger includes cancellation (suspending) when freezing and the like are performed before freezing and the like.

根據本發明，可提供可取消室內熱交換器的洗淨的空調機。 According to the present invention, it is possible to provide an air conditioner capable of eliminating washing of an indoor heat exchanger.

又，在圖1雖省略，可是室內機10與室外機30經由冷媒配管被連接，並且經由通訊線路被連接。 　　[0012] 圖2為室內機10的縱剖視圖。 　　室內機10除了前述的通訊部11(參照圖1)之外，具備有：室內熱交換器12；排水盤13；室內風扇14；框體基體15；濾網16、16；前面面板17；左右風向板18；以及上下風向板19。 　　[0013] 室內熱交換器12，是進行在傳熱管12a流通的冷媒、與室內空氣的熱交換的熱交換器。 　　排水盤13，是承接從室內熱交換器12滴落的水者，被配置在室內熱交換器12的下側。此外，落下到排水盤13的水經由排液管(未圖示)被排出到外部。 　　[0014] 室內風扇14，是例如圓筒狀的橫流扇，藉由室內風扇馬達14a(參照圖4)驅動。 　　框體基體15，是設置室內熱交換器12、室內風扇14等的機器的框體。 　　[0015] 濾網16、16，是從經由空氣吸入口h1等吸入的空氣去除塵埃者，並被設置在室內熱交換器12的上側・前側。 　　前面面板17，是覆蓋前側的濾網16地被設置的板件，並以下端為軸形成可朝前側轉動。此外，前面面板17也可為不轉動的構造。 　　[0016] 左右風向板18，是在左右方向調整朝向室內吹出的空氣的流通方向的板狀構件。左右風向板18被配置在室內風扇14的下游側，而形成藉由左右風向板用馬達23(參照圖4)朝左右方向轉動。 　　上下風向板19，是在上下方向調整朝向室內被吹出的空氣的流通方向的板狀構件。上下風向板19被配置在室內風扇14的下游側，而形成藉由上下風向板用馬達24(參照圖4)朝上下方向轉動。 　　[0017] 經由空氣吸入口h1被吸入的空氣與在傳熱管12a流通的冷媒作熱交換，並將熱交換後的空氣引導到吹出風路h2。而且，在吹出風路h2流通的空氣藉由左右風向板18及上下風向板19朝預定方向被引導，而進一步經由空氣吹出口h3朝室內吹出。 　　[0018] 圖3表示空調機100的冷媒回路Q的說明圖。 　　此外，圖3的實線箭頭印表示暖房運轉時的冷媒的流動。 　　又，圖3的虛線箭頭印表示冷房運轉時的冷媒的流動。 　　如圖3所示，室外機30具備：壓縮機31、室外熱交換器32、室外風扇33、室外膨脹閥34(膨脹閥)、以及四通閥35。 　　[0019] 壓縮機31，是藉由壓縮機馬達31a的驅動，壓縮低溫低壓的氣態冷媒，作成高溫高壓的氣體冷媒吐出的機器。 　　室外熱交換器32，是在其傳熱管(未圖示)流通的冷媒、與從室外風扇33送入的外氣之間進行熱交換的熱交換器。 　　[0020] 室外風扇33，是藉由室外風扇馬達33a將外氣送入室外熱交換器32的風扇，且被設置室外熱交換器32的附近。 　　室外膨脹閥34具有減壓在「冷凝器」(室外熱交換器32及室內熱交換器12的一方)冷凝後的冷媒的功能。此外，在室外膨脹閥34被減壓的冷媒被引導到「蒸發器」(室外熱交換器32及室內熱交換器12的另一方)。 　　[0021] 四通閥35，是依照空調機100的運轉模式切換冷媒的流路的閥。亦即，在冷房運轉時(參照圖3的虛線箭頭印)，是在經由四通閥35環狀依序連接壓縮機31、室外熱交換器32(冷凝器)、室外膨脹閥34、及室內熱交換器12(蒸發器)而成的冷媒回路Q，使冷媒在冷凍循環中循環。 　　[0022] 又，在暖房運轉時(參照圖3的實線箭頭印)，是在經由四通閥35環狀依序連接壓縮機31、室內熱交換器12(冷凝器)、室外膨脹閥34、及室外熱交換器32(蒸發器)而成的冷媒回路Q，使冷媒在冷凍循環中循環。 　　[0023] 亦即，冷媒回路Q中，前述的「冷凝器」及「蒸發器」的一方是室外熱交換器32，另一方是室內熱交換器12。 　　[0024] 圖4是空調機100的功能方塊圖。 　　室內機10除了前述的構造之外，具備環境檢測部21、室內控制電路22、通知音產生部25(通知手段)、以及顯示燈26(通知手段)。 　　[0025] 環境檢測部21具有檢測室內(被空調空間)的狀態的功能，並具備室內溫度感測器21a等。 　　室內溫度感測器21a，是檢測室內的溫度的感測器。含有室內溫度感測器21a的各感測器的檢測值被輸出到室內控制電路22。 　　[0026] 室內控制電路22雖未圖示，卻含有：CPU(Central Processing Unit)、ROM(Read Only Memory)、RAM(Random Access Memory)、各種介面等的電子電路被構成。而且，形成讀取被ROM所記憶的程式在RAM展開，使CPU執行各種處理。 　　[0027] 如圖4所示，室內控制電路22具備：記憶部22a、與室內控制部22b。 　　在記憶部22a除了預定的程式之外，記憶有環境檢測部21的檢測結果、經由通訊部11所接收的資料等。 　　室內控制部22b依據記憶部22a所記憶的資料執行預定的控制。此外，關於室內控制部22b執行的處理容後敘述。 　　[0028] 通知音產生部25具有讓預定的通知音從收容室內熱交換器12的室內機10產生的功能。亦即，通知音產生部25，是藉由讓所謂蜂鳴器、聲音的通知音產生，進行關於空調的預定的通知。 　　顯示燈26，是例如LED(Light Emitting Diode)，藉由以預訂的顏色亮燈(或閃爍)，進行關於空調的預定的通知。 　　此外，通知音產生部25產生的聲音、顯示燈26的顏色，是與通知內容對應預先被記憶在記憶部22a。 　　[0029] 圖4所示的室外機30除了前述的構造之外，具備室外控制電路36。 　　室外控制電路36雖未圖示，卻含有：CPU、ROM、RAM、各種介面等的電子電路被構成，並經由通訊線路連接於室內控制電路22。如圖4所示，室外控制電路36具備：記憶部36a、與室外控制部36b。 　　[0030] 在記憶部36a，除了預定的程式、從室內控制電路22所接收的資料之外，記憶有複數個感測器(在圖4省略圖示的外部氣溫度感測器、壓縮機31的吸入壓力感測器、吐出壓力感測器、吐出溫度感測器等)的檢測值。 　　室外控制部36b依據被記憶部36a所記憶的資料，控制壓縮機馬達31a、室外風扇馬達33a、室外膨脹閥34等。 　　[0031] 以下將室內控制電路22及室外控制電路36稱為「控制部K」(控制手段)。控制部K，是具有依據來自遙控器40或可攜式終端機50的訊號控制壓縮機31(參照圖3)、室外膨脹閥34等的功能。 　　[0032] 接著，針對洗淨室內熱交換器12用的處理進行說明。 　　如前述，在室內熱交換器12(參照圖2)的上側・前側(空氣的吸入側)設置捕集塵土、灰塵用的濾網16。然而，因為會有細的塵土、灰塵穿過濾網16附著在室內熱交換器12的情況，所以，期望能定期洗淨室內熱交換器12。於此，在本實施形態，讓含在被室內機10所吸入的空氣的水分在室內熱交換器12凍結，之後，溶解室內熱交換器12的冰。藉此，因為能洗去附著在室內熱交換器12的塵土、灰塵，所以能洗淨室內熱交換器12。將這樣的一連串的處理稱為室內熱交換器12的「洗淨處理」。 　　[0033] 圖5，是執行空調機100的控制部K的洗淨處理的流程圖(適當參照圖3、圖4)。此外，設定成直到圖5的「START」時為止進行預定的空調運轉(冷房運轉、暖房運轉等)者。 　　又，設定成室內熱交換器12的洗淨處理的開始條件在圖5的「START」時成立者。該「開始條件」，是所謂例如從前次的洗淨處理結束時累計空調運轉的執行時間的值達到預定值的條件。 　　[0034] 在步驟S101，控制部K讓空調運轉停止預定時間(例如幾分鐘)。前述的預定時間，是讓冷凍循環穩定用的時間，而被預先設定。例如，直到「START」時為止讓進行的暖房運轉中斷，讓室內熱交換器12凍結時(S102)，控制部K控制四通閥35使冷媒朝向與暖房運轉時相反方向(與冷房運轉時同樣的方向)流動。於此，假設若突然改變冷媒的流向，對壓縮機31會造成過載，還有導致冷凍循環的不穩定化的可能性。於此，本實施形態，是在室內熱交換器12的凍結(S102)之前預定時間讓空調運轉停止(S101)。 　　[0035] 此外，中斷冷房運轉讓室內熱交換器12凍結時，也可省略步驟S101的處理。冷房運轉中(圖5的START時)冷媒的流向、與室內熱交換器12的凍結中(S102)冷媒的流向相同。 　　[0036] 接著，在步驟S102，控制部K讓室內熱交換器12凍結。亦即，控制部K，是讓室外熱交換器32作為冷凝器發揮功能，讓室內熱交換器12作為蒸發器發揮功能。藉此，可讓含在被室內機10所吸入的空氣的水分在室內熱交換器12凍結。 　　[0037] 讓室內熱交換器12凍結時，適當調整壓縮機31的旋轉速度，又，調整室外膨脹閥34的開度使室內熱交換器12的溫度在預定範圍內。前述的「預定範圍」，是指含在被室內機10所吸入的空氣的水分能在室內熱交換器12凍結的範圍，並預先被設定。 　　[0038] 此外，讓室內熱交換器12凍結時(亦即，直至預定的凍結時間為止)，控制部K也可讓室內風扇14停止，又，也可以讓室內風扇14驅動。 　　[0039] 在步驟S103，控制部K解凍室內熱交換器12。例如，控制部K，是讓室內熱交換器12作為冷凝器發揮功能，讓室外熱交換器32作為蒸發器發揮功能。藉此，為了經由作為冷凝器的室內熱交換器12流動高溫的冷媒，而使室內熱交換器12的冰溶解。其結果，能洗掉附著在室內熱交換器12的塵土、灰塵。而且，含塵土、灰塵的水落下到排水盤13(參照圖2)，並經由排液管(未圖示)排出到外部。 　　此外，室內熱交換器12的解凍中，控制部K也可讓室內風扇14驅動。藉此，可抑制室內熱交換器12(冷凝器)的溫度變的過高的情況。 　　[0040] 又，控制部K進行送風運轉，或者讓含有壓縮機31、室內風扇14的機器的停止狀態持續，也可解凍室內熱交換器12(S103)。控制部K即使不讓室內熱交換器12作為冷凝器發揮功能，由於室內熱交換器12的冰也會在室溫自然解凍。藉此，可減低室內熱交換器12的解凍所需要的消耗功率。 　　[0041] 在步驟S104，控制部K讓室內熱交換器12乾燥。例如，控制部K，是讓室內熱交換器12作為冷凝器發揮功能，讓室外熱交換器32作為蒸發器發揮功能。如此，因為進行與暖房運轉時同樣的控制，而使附著在室內熱交換器12的水分蒸發，所以，能達到防菌・防黴的效果。進行步驟S104的處理後，控制部K結束一連串的「洗淨處理」(END)。 　　[0042] 此外，控制部K進行送風運轉(亦即，進行將空氣送入室內熱交換器12的室內風扇14的驅動)，也可使室內熱交換器12乾燥(S104)。接著，針對開始室內熱交換器12的洗淨處理時的動作詳細地說明。 　　[0043] 圖6，是表示開始洗淨處理時的控制部K的處理的流程圖(適當參照圖3、圖4)。 　　在步驟S201，控制部K判定洗淨處理的開始條件是否成立。如前述，「洗淨處理的開始條件」，是所謂例如從前次的洗淨處理結束時累計空調運轉的時間的值達到預定值的條件。在步驟S201，洗淨處理的開始條件成立時(S201：Yes)，控制部K的處理進到步驟S202。另一方面，洗淨處理的開始條件不成立時(S201：No)，控制部K結束一連串的處理(END)。 　　[0044] 在步驟S202，控制部K，是藉由通知音產生部25讓預定的通知音產生、或讓顯示燈26亮燈。亦即，控制部K在開始室內熱交換器12的凍結等的洗淨處理之前，藉由通知音產生部25及顯示燈26通知進行該洗淨處理之意。藉此，可對使用者事前通知開始洗淨處理的情況。 　　[0045] 接著，在步驟S203，控制部K設定直至開始室內熱交換器12的洗淨處理為止的延遲時間(亦即，待機時間)。該延遲時間(例如數秒~數十秒)，是在步驟S202，事前通知使用者開始洗淨處理之意起到實際開始洗淨運轉的時間，且被預先設定。 　　[0046] 在步驟S204，控制部K，是從事前通知使用者開始洗淨處理之意(S202)起判定是否經過預定的延遲時間。經過預定延遲時間時(S204：Yes)，控制部K的處理進入步驟S205。也可直到經過該延遲時間的期間持續顯示燈26的亮燈等(S202)。 　　在步驟S205，控制部K執行室內熱交換器12的洗淨處理(圖5的S101～S104)。 　　[0047] 另一方面，在步驟S204沒有經過預定的延遲時間時候(S204：No)，控制部K的處理進到步驟S206。 　　在步驟S206，控制部K，是藉由遙控器40或可攜式終端機50的操作判定是否有洗淨處理的取消指令。沒有洗淨處理的取消指令時(S206：No)、控制部K的處理回到步驟S204。另一方面，有洗淨處理的取消指令時(S204：Yes)、控制部K的處理進到步驟S207。 　　[0048] 在步驟S207，控制部K，是藉由通知音產生部25讓預定的通知音產生、或讓顯示燈26亮燈。藉此，可依照遙控器40等的操作，將實際取消了洗淨運轉的情況通知使用者。 　　[0049] 此外，前述的通知音等(S207)，是與事前通知洗淨處理用的通知音等(S202)不同種類者為期望。藉此，可讓使用者容易理解地通知實際取消了洗淨處理的情況。 　　[0050] 接著，在步驟S208，控制部K取消室內熱交換器12的洗淨處理。亦即，控制部K，是依據來自遙控器40或可攜式終端機50的訊號取消包含室內熱交換器12的凍結的洗淨處理。更詳細地說明的話，從開始洗淨處理前的通知(S202)到經過預定的延遲時間(預定時間)為止，從遙控器40或可攜式終端機50接收到預定的取消指令時(S204：No、S206：Yes)，控制部K不進行包含室內熱交換器12的凍結的洗淨處理(S208)。藉此，控制部K可順著使用者的旨意，適當取消室內熱交換器12的洗淨處理。而且，進行步驟S208的處理後，控制部K結束一連串的處理(END)。 　　[0051] ＜效果＞ 　　根據第1實施形態，控制部K，是在室內熱交換器12的洗淨處理之前，通知進行洗淨處理的旨意(S202)。藉此，之後可對使用者事前通知進行洗淨處理的情況。 　　[0052] 又，從洗淨處理的事前通知(S202)到經過預定的延遲時間有取消指令時(S204：No、S206：Yes)，控制部K取消洗淨處理(S208)。藉此，可避免違反使用者的旨意進行洗淨處理的情況。換言之，可順著使用者的旨意，進行室內熱交換器12的洗淨處理。 　　[0053] ≪第2實施形態≫ 　　第2實施形態，是針對在室內熱交換器12(參照圖2)的洗淨處理中有取消指令的情況的處理進行說明的點與第1實施形態不同。此外，關於其他的點(圖1～圖4所示的空調機100的結構、圖5所示的洗淨處理的流程圖)與第1實施形態同樣。因此，針對與第1實施形態不同的部分進行說明，關於重複的部分省略說明。 　　[0054] 圖7，是表示洗淨處理中的控制部K的處理的流程圖(適當參照圖3、圖4)。 　　在步驟S301，控制部K判定現在是否進行洗淨處理。此外，關於洗淨處理，是如第1實施形態(參照圖5)所說明。 　　[0055] 此外，在圖7雖省略，可是進行包含室內熱交換器12的凍結的洗淨處理時，控制部K也可藉由通知音產生部25、顯示燈26通知是在洗淨處理中。藉此，使用者容易掌握進行室內熱交換器12的洗淨處理的情況。而且，例如使用者不希望洗淨處理的持續時，藉由遙控器40等的操作將預定的取消指令傳送到室內機10。 　　[0056] 在圖7的步驟S301，目前在洗淨處理中的時候(S301：Yes)，控制部K的處理進到步驟S302。另一方面，目前沒有進行洗淨處理時(S301：No)，控制部K結束處理(END)。 　　[0057] 在步驟302，控制部K，是藉由遙控器40或可攜式終端機50的操作判定是否有洗淨處理的取消指令。沒有洗淨處理的取消指令時(S302：No)，控制部K持續洗淨處理之後，結束一連串的處理(END)。另一方面，有洗淨處理的取消指令時(S302：Yes)、控制部K的處理進到步驟S303。 　　[0058] 接著，在步驟S303，控制部K判定是否從室內熱交換器12的凍結開始時經過預定時間。此「預定時間」(例如幾分鐘)，是將作為蒸發器發揮功能的室內熱交換器12充分冷卻(含在空氣的水分冷卻到在室內熱交換器12冷卻到凍結的程度)為止的時間，且被預先設定。 　　[0059] 在步驟S303從室內熱交換器12的凍結開始時經過預定時間的時候(S303：Yes)，控制部K的處理進到步驟S304。具體說明的話，除了室內熱交換器12的凍結加深的情況之外，進行室內熱交換器12的解凍(圖5的S103)、乾燥(圖5的S104)時，控制部K的處理進到步驟S304。 　　[0060] 在步驟S304，控制部K，是藉由通知音產生部25讓預定的通知音產生，又讓顯示燈26亮燈。藉此，如後述，可將有洗淨處理的取消指令者(S302：Yes)，尤其，可將持續洗淨處理(S305的「乾燥」)之意通知使用者。 　　[0061] 接著，在步驟S305，控制部K讓室內熱交換器12乾燥。例如，凍結中經過預定時間以上時(S303：Yes)，會有冰附著在室內熱交換器12的表面的可能性。讓該冰在室溫溶解之後的水蒸發，進一步使其乾燥(S305)能達到防菌・防黴的效果。 　　又，室內熱交換器12的解凍中(S303：Yes)，室內熱交換器12的冰溶解，其一部分滴落到排水盤13(參照圖2)，剩下的附著在室內熱交換器12。讓如此附著的水乾燥(S305)能達到防菌・防黴的效果。 　　又，室內熱交換器12的乾燥中(S303：Yes)，讓其乾燥持續(S305)，而使室內熱交換器12成為乾淨的狀態 　　[0062] 如此，從開始包含室內熱交換器12的凍結的洗淨處理到經過預定時間之後(S303：Yes)，從遙控器40或可攜式終端機50接收到洗淨處理的取消指令時(S302：Yes)，控制部K讓室內熱交換器12乾燥(S305)。 　　[0063] 此外，關於步驟S305的處理內容，與在第1實施形態說明的步驟S104(參照圖5)同樣。若舉其一例，控制部K進行暖房運轉(讓室內熱交換器12作為冷凝器發揮功能)，讓室內熱交換器12乾燥。 　　[0064] 接著，在步驟S306，控制部K判定是否有再次的取消指令。亦即，控制部K在取消指令的接收後，在室內熱交換器12的乾燥中，判定是否從遙控器40或可攜式終端機50再次接受到預定的取消指令。 　　[0065] 在步驟S306沒有再次的取消指令時(S306：No)，控制部K的處理回到步驟S305。此時就這樣持續室內熱交換器12的乾燥。 　　另一方面，在步驟S306有再次的取消指令時(S306：Yes)，控制部K的處理進到步驟S307。 　　[0066] 在步驟S307，控制部K，是藉由通知音產生部25讓預定的通知音產生，又讓顯示燈26亮燈。藉此，依照洗淨處理的取消指令可通知使用者實際中止洗淨處理(亦即，室內熱交換器12的乾燥)(S308)的情況。 　　[0067] 在步驟S308，控制部K中止室內熱交換器12的乾燥。藉此，即使在室內熱交換器12的乾燥中，也可適當反映所謂想中止其處理的使用者的旨意。進行步驟S308的處理之後，控制部K結束一連串的處理(END)。 　　[0068] 又，在步驟S303沒有從室內熱交換器12的凍結開始時經過預定時間的時候(S303：No)，控制部K的處理進到步驟S309。 　　在步驟S309，控制部K，是藉由通知音產生部25讓預定的通知音產生，又讓顯示燈26亮燈。藉此，可將中止室內熱交換器12的凍結(S310)之旨通知使用者。 　　[0069] 在步驟S310，控制部K中止室內熱交換器12的凍結。此時，因為在室內熱交換器12幾乎沒有附著冰，所以，即使中止室內熱交換器12的凍結也不會有阻礙產生。亦即，幾乎不會有許多的水分附著在室內熱交換器12的表面而產生細菌、發霉的顧慮。 　　[0070] 如此，從開始室內熱交換器12的凍結經過預定時間之前(S303：No)，從遙控器40或可攜式終端機50接收到前述的凍結的取消指令時(S302：Yes)，控制部K中止其凍結(S310)。進行步驟S310的處理之後，控制部K結束一連串的處理(END)。 　　[0071] ＜效果＞ 　　根據第2實施形態，在室內熱交換器12的洗淨處理中接收到取消指令時(S302：Yes)，從凍結開始時經過預定時間時(S303：Yes)，控制部K還是執行室內熱交換器12的乾燥(S305)。藉此，防止許多的水附著在室內熱交換器12的表面，達到防菌・防黴的效果。 　　[0072] 又，在室內熱交換器12的乾燥中有再次的取消指令時(S306：Yes)，控制部K中止室內熱交換器12的乾燥(S308)。藉此，即使在室內熱交換器12的乾燥中，也可適當反映所謂想中止其處理的使用者的旨意。 　　[0073] 又，在室內熱交換器12的洗淨處理中接收到取消指令時(S302：Yes)，從凍結開始時沒有經過預定時間時(S303：No)，控制部K中止室內熱交換器12的凍結(S310)。藉此，可適當反映所謂想取消洗淨處理(凍結)的使用者的旨意。 　　[0074] ≪第3實施形態≫ 　　第3實施形態，是針對在室內熱交換器12的洗淨處理中接收到空調運轉的運轉指令時的處理進行說明的點與第1實施形態不同。此外，關於其他的點(圖1～圖4所示的空調機100的結構、圖5所示的洗淨處理的流程圖)與第1實施形態同樣。因此，針對與第1實施形態不同的部分進行說明，關於重複的部分省略說明。 　　[0075] 圖8表示洗淨處理中或洗淨處理後的控制部K的處理的流程圖(適當參照圖3、圖4)。 　　在步驟S401，控制部K判定在室內熱交換器12的洗淨處理中是否從遙控器40或可攜式終端機50接收到空調運轉(暖房運轉、冷房運轉等)的運轉指令。洗淨處理中接收到空調運轉的運轉指令時(S401：Yes)，控制部K的處理進到步驟S403。此時，會有在室內熱交換器12凍結的冰之後溶解、或解凍後的水附著在室內熱交換器12的可能性。另一方面，洗淨處理中沒有接收到空調運轉的運轉指令時(S401：No)，控制部K的處理進到步驟S402。 　　[0076] 在步驟S402，控制部K判定從室內熱交換器12的洗淨處理的取消的預定時間內是否接收到空調運轉的運轉指令。從洗淨處理的取消時的預定時間內沒有接收到運轉指令時(S402：No)，控制部K結束一連串的處理(END)。 　　[0077] 另一方面，從洗淨處理的取消時的預定時間內接收到運轉指令時(S402：Yes)，控制部K的處理進到步驟S403。此時，為了在中途中止洗淨處理，會有在室內熱交換器12凍結的冰之後溶解、而弄濕室內熱交換器12的表面的可能性。 　　[0078] 在步驟S403，控制部K，是藉由通知音產生部25讓預定的通知音產生，又讓顯示燈26亮燈。藉此，可將接收到空調運轉的運轉指令之意通知使用者。 　　[0079] 在步驟S404，控制部K停止(或中止)室內熱交換器12的洗淨處理。亦即，控制部K讓包含壓縮機31、室內風扇14的各機器停止。 　　在步驟S405，控制部K判定是否從洗淨處理的停止時(或中止時)經過預定時間。該「預定時間」，是讓各機器的停止狀態持續，讓室內熱交換器12乾燥(讓附著在其表面的水分蒸發)所需要的時間，且被預先設定。 　　[0080] 在步驟S405，從洗淨處理的停止時經過預定時間的時候(S405：Yes)，控制部K的處理進到步驟S406。另一方面，沒有從洗淨處理的停止時經過預定時間的時候(S405：No)，控制部K的處理回到步驟S404。 　　[0081] 在步驟S406，控制部K設定進行室內熱交換器12的乾燥用的執行時間。例如，控制部K為了讓室內熱交換器12乾燥，而設定暖房運轉或送風運轉的執行時間。 　　[0082] 在步驟S407，控制部K執行室內熱交換器12的乾燥。例如，控制部K，是進行暖房運轉或送風運轉讓室內熱交換器12乾燥。此外，也可進行暖房運轉，並在這之後進行送風運轉讓室內熱交換器12乾燥。 　　[0083] 在步驟S408，控制部K判定是否從室內熱交換器12的乾燥的開始時經過預定的執行時間(在S406設定)。經過預定的執行時間時(S408：Yes)，控制部K的處理進入步驟S409。此時，包含室內熱交換器12，充分乾燥室內機10的內部。 　　另一方面，沒有從室內熱交換器12的乾燥的開始時經過預定的執行時間的時候(S408：No)，控制部K的處理回到步驟S407。 　　[0084] 而且，在步驟S409，控制部K依據在步驟S401或S402所接收的運轉指令執行預定的空調運轉。進行步驟S409的處理之後，控制部K結束一連串的處理(END)。 　　[0085] ＜效果＞ 　　根據第3實施形態，在從室內熱交換器12的洗淨處理中或其取消時的預定時間內接收到運轉指令的時候(S401或S402：Yes)，控制部K依序進行洗淨處理的停止及室內熱交換器12的乾燥之後(S404～S408)，執行空調運轉(S409)。藉此，即使在室內熱交換器12濕掉的狀態下接收到空調運轉的運轉指令時，也可讓室內機10的內部充分乾燥之後執行空調運轉。 　　[0086] ≪變形例≫ 　　以上，雖在各實施形態針對本發明的空調機100進行說明，可是本發明並不限於該等的記載者，可進行各種的變更。 　　例如，在各實施形態，就「洗淨處理」來說，雖針對依序進行室內熱交換器12的凍結・解凍・乾燥的情況進行說明(圖5的S102～S104)，可是不限於此。例如，也可省略室內熱交換器12的解凍・乾燥中的一方或兩方。即使此時，由於在室溫自然解凍室內熱交換器12，而可藉由其水洗淨室內熱交換器12。又，由於可藉由各機器的停止狀態的持續、之後的空調運轉等，使室內熱交換器12乾燥。 　　[0087] 又，在各實施形態，雖針對藉由讓室內熱交換器12凍結洗淨室內熱交換器12的處理進行說明，可是不限於此。例如，藉由讓室內熱交換器12結露，也可洗淨室內熱交換器12。此時，控制部K，是將冷媒的蒸發溫度設的比通常的冷房運轉、除濕運轉更低。若具體地說明，控制部K，是依據室內溫度感測器21a(參照圖4)的檢測值、與濕度感應器(未圖示)的檢測值算出室內空氣的露點。然後，控制部K，是調整室外膨脹閥34的開度等使室內熱交換器12的溫度在前述的露點以下，且變的比預定的凍結溫度更高。 　　此外，前述的「凍結溫度」，是指讓室內空氣的溫度降低時，室內空氣所含有水分在室內熱交換器12凍結開始的溫度。如此，讓室內熱交換器12結露，而可藉由其結露水洗淨室內熱交換器12。 　　[0088] 而且，也可讓室內熱交換器12結露之後，控制部K讓室內熱交換器12乾燥。亦即，讓室內熱交換器12結露時，控制部K，是讓室內熱交換器12作為冷凝器發揮功能、或執行送風運轉，讓室內熱交換器12乾燥。 　　[0089] 又，控制部K也可在暖房運轉、冷房運轉、或除濕運轉之後進行室內熱交換器12的凍結、或結露。藉此，可在暖房運轉、冷房運轉、除濕運轉等的空調運轉後洗淨室內熱交換器12。 　　[0090] 又，除了室內熱交換器12的凍結、結露之外，也可在暖房運轉後進行冷房運轉洗淨室內熱交換器12。藉此，使水分附著在被冷媒所冷卻的室內熱交換器12，並藉由該水分洗去室內熱交換器12。 　　[0091] 此外，所謂藉由室內熱交換器12的結露、暖房運轉後的冷房運轉洗淨室內熱換器12的事項可適用在各實施形態。具體而言，只要進行室內熱交換器12的結露、或(暖房運轉後的)冷房運轉取代圖5的步驟S102(凍結)及步驟S103(解凍)的處理即可。 　　[0092] 又，在各實施形態，雖藉由室內機10的顯示燈26等(參照圖4)進行針對關於空調的預定的通知的處理進行說明，可是不限於此。例如，也可將進行前述的通知用的顯示器(未圖示)設在室內機10，並在顯示器顯示預定的圖樣、文字等。又，也可使用遙控器40(參照圖4)或可攜式終端機50(參照圖4)進行預定的通知。亦即，「通知手段」也可藉由在室內機10、遙控器40、或可攜式終端機50進行預定的顯示來進行關於空調的預定的通知。 　　[0093] 又，在各實施形態，雖藉由通知音產生部25及顯示燈26針對進行關於空調運轉的預定的通知時進行說明，可是不限於此。例如，也可使用通知音產生部25及顯示燈26中的一方進行預定的通知，又，也可適當省略通知的處理。 　　[0094] 又，在預定的時段，通知音產生部25也可讓通知音不要產生。例如，在夜間的時段讓通知音不要產生，可防止使用者的舒適性受到損害。 　　[0095] 其他，也可藉由打開收容室內熱交換器12的室內機10的上下風向板19(參照圖2)，通知在進行包含凍結的洗淨處理。此時，控制部K使上下風向板19比水平更朝上為理想。藉此，可防止冷風直接碰到使用者的情況。 　　[0096] 又，在第3實施形態(參照圖8)，為了讓室內熱交換器12乾燥，雖針對控制部K進行步驟S406～S408的各處理的情況進行說明，可是也可省略該等的處理。例如，包含室內熱交換器12的凍結(或是結露、或者暖房運轉後的冷房運轉)的洗淨處理中，從遙控器40或可攜式終端機50接收到空調運轉的運轉指令時(圖8的S401：Yes)，控制部K中止(停止)洗淨處理(S404)。而且，控制部K，是從中止洗淨處理經過預定時間之後，依據運轉指令開始空調運轉。中止洗淨處理讓各機器停止的期間，室內熱交換器12的冰自然解凍並使其水蒸發。藉此，可進行室內熱交換器12的解凍・乾燥。 　　[0097] 又，例如，從依據來自遙控器40或可攜式終端機50的取消指令中止包含室內熱交換器12的凍結(或是結露、或者暖房運轉後的冷房運轉)的洗淨處理經過預定時間之前，從遙控器40或可攜式終端機50接收到空調運轉的運轉指令時(圖8的S402：Yes)，控制部K也可進行接下來的處理。亦即，控制部K，也可從中止洗淨處理經過前述預定時間之後，依據運轉指令開始空調運轉。中止洗淨處理讓各機器停止的期間，由於室內熱交換器12的冰自然解凍而使其水蒸發。 　　[0098] 又，在第3實施形態，即使步驟S401或S402的條件成立時，當控制部K接收到的運轉指令為暖房運轉的指令時，也可省略步驟S406～S408的處理(室內熱交換器12的乾燥)。由於是藉由之後的暖房運轉，使室內熱交換器12乾燥。 　　[0099] 又，控制部K也可將使室內熱交換器12凍結或結露時的冷媒的蒸發溫度設的比除濕運轉中的冷媒的蒸發溫度更低。又，控制部K也可將使室內熱交換器12凍結或結露時的冷媒的蒸發溫度設在冰點下。進行這樣的控制，藉由室內熱交換器12的凍結或結露使許多的水分(冰、露)附著在室內熱交換器12。其結果，藉由附著在室內熱交換器12的水分，可有效果地洗淨室內熱交換器12。 　　[0100] 又，各實施形態雖針對各設一台室內機10(參照圖3)及室外機30(參照圖3)的構造進行說明，可是不限於此。亦即，也可設置並列連接的複數台的室內機，又，也可設置並列連接的複數台的室外機。 　　[0101] 又，各實施形態是為了容易明白本發明的說明而進行詳細記載者，並不是限定一定要具備所說明的全部的構造者。又，可針對各實施形態的構造的一部分，進行其他的構造的追加・消除・置換。 　　又，前述的機構、構造表示說明上必要者，而不限於產品上一定顯示有全部的機構、構造。[0009] ≪First Embodiment≫ <Configuration of Air Conditioner> FIG. 1, The indoor unit 10 included in the air conditioner 100 according to the first embodiment,

As shown in Figure 4, The outdoor control circuit 36 includes: Memory section 36a, With outdoor control unit 36b.  [0030] In the memory section 36a, In addition to scheduled programs, In addition to the data received from the indoor control circuit 22, There are a plurality of sensors (an outside air temperature sensor, not shown in FIG. 4, Suction pressure sensor of compressor 31, Spit out pressure sensor, Discharge the detection value of temperature sensor, etc.).  The outdoor control unit 36b is based on the data stored by the storage unit 36a. Control compressor motor 31a, Outdoor fan motor 33a, Outdoor expansion valve 34 and the like.  [0031] Hereinafter, the indoor control circuit 22 and the outdoor control circuit 36 are referred to as "control section K" (control means). Control unit K, Is to control the compressor 31 (refer to FIG. 3) based on a signal from the remote control 40 or the portable terminal 50, Functions of the outdoor expansion valve 34 and the like.  [0032] Next, A process for cleaning the indoor heat exchanger 12 will be described.  前述 As mentioned before, Dust traps are installed on the upper and front sides of the indoor heat exchanger 12 (see Figure 2) Dust filter 16. however, Because there will be fine dust, When dust passes through the filter 16 and attaches to the indoor heat exchanger 12, and so, It is desirable to clean the indoor heat exchanger 12 regularly. herein, In this embodiment, Freeze the moisture contained in the air sucked into the indoor unit 10 in the indoor heat exchanger 12, after that, The ice in the indoor heat exchanger 12 is dissolved. With this, Because it is possible to wash away the dust attached to the indoor heat exchanger 12, dust, Therefore, the indoor heat exchanger 12 can be cleaned. Such a series of processes is referred to as “cleaning process” of the indoor heat exchanger 12.  [0033] Figure 5, It is a flowchart which performs the washing process of the control part K of the air conditioner 100 (refer FIG. 3 suitably, Figure 4). In addition, It is set to perform a predetermined air-conditioning operation (cooling operation, Greenhouse operation, etc.).  Alas, The start condition of the washing process of the indoor heat exchanger 12 is set at "START" of FIG. The "start condition" This is a condition that, for example, the value of the accumulated execution time of the air-conditioning operation has reached a predetermined value from the end of the previous cleaning process.  [0034] In step S101, The control unit K stops the air-conditioning operation for a predetermined time (for example, several minutes). The aforementioned predetermined time, Is the time it takes to stabilize the refrigeration cycle, It is preset. E.g, Stop the greenhouse operation until "START", When the indoor heat exchanger 12 is frozen (S102), The control unit K controls the four-way valve 35 so that the refrigerant flows in a direction opposite to that during the heating operation (the same direction as during the cooling operation). herein, Suppose if the flow of refrigerant is suddenly changed, Overloading the compressor 31, There is also a possibility of destabilizing the refrigeration cycle. herein, This embodiment, The air-conditioning operation is stopped a predetermined time before the indoor heat exchanger 12 is frozen (S102) (S101).  [0035] In addition, When the cold room operation is interrupted and the indoor heat exchanger 12 freezes, The process of step S101 may be omitted. The flow of refrigerant during cold room operation (at the time of START in Figure 5), The flow direction of the refrigerant is the same as that during the freezing (S102) of the indoor heat exchanger 12.  [0036] Then, In step S102, The control unit K freezes the indoor heat exchanger 12. that is, Control unit K, Is to make the outdoor heat exchanger 32 function as a condenser, The indoor heat exchanger 12 is allowed to function as an evaporator. With this, The moisture contained in the air sucked into the indoor unit 10 can be frozen in the indoor heat exchanger 12.  [0037] When the indoor heat exchanger 12 is frozen, Appropriately adjust the rotation speed of the compressor 31, also, The opening degree of the outdoor expansion valve 34 is adjusted so that the temperature of the indoor heat exchanger 12 is within a predetermined range. The aforementioned "predetermined range" The range in which the moisture contained in the air sucked into the indoor unit 10 can be frozen in the indoor heat exchanger 12, And set in advance.  [0038] In addition, When the indoor heat exchanger 12 is allowed to freeze (that is, Until the scheduled freeze time), The control unit K can also stop the indoor fan 14, also, The indoor fan 14 may be driven.  [0039] In step S103, The control unit K thaws the indoor heat exchanger 12. E.g, Control unit K, Is to make the indoor heat exchanger 12 function as a condenser, The outdoor heat exchanger 32 is allowed to function as an evaporator. With this, In order to flow a high-temperature refrigerant through the indoor heat exchanger 12 as a condenser, Then, the ice in the indoor heat exchanger 12 is dissolved. the result, Can wash away dust and dirt adhering to the indoor heat exchanger 12, dust. and, Dusty, Dust water falls to the drain pan 13 (see FIG. 2), It is discharged to the outside through a drain pipe (not shown).  Additionally, During thawing of the indoor heat exchanger 12, The control unit K may drive the indoor fan 14. With this, It is possible to prevent the temperature of the indoor heat exchanger 12 (condenser) from becoming excessively high.  [0040] Again, The control unit K performs a blower operation, Or let the compressor 31, The stopped state of the equipment of the indoor fan 14 continues, The indoor heat exchanger 12 may be thawed (S103). Even if the control unit K does not allow the indoor heat exchanger 12 to function as a condenser, Since the ice of the indoor heat exchanger 12 will naturally thaw at room temperature. With this, The power consumption required for defrosting the indoor heat exchanger 12 can be reduced.  [0041] In step S104, The control unit K dries the indoor heat exchanger 12. E.g, Control unit K, Is to make the indoor heat exchanger 12 function as a condenser, The outdoor heat exchanger 32 is allowed to function as an evaporator. in this way, Because the same control as in the greenhouse operation is performed, And evaporating the water adhering to the indoor heat exchanger 12, and so, Can achieve antibacterial and antifungal effects. After performing the processing of step S104, The control unit K ends a series of "washing processes" (END).  [0042] In addition, The control unit K performs a blower operation (that is, Driving the indoor fan 14 that sends air into the indoor heat exchanger 12), The indoor heat exchanger 12 may be dried (S104). then, The operation when starting the cleaning process of the indoor heat exchanger 12 will be described in detail.  [0043] FIG. 6, A flowchart showing the processing of the control unit K when the washing process is started (refer to FIG. 3 as appropriate, Figure 4).  In step S201, The control unit K determines whether or not the start condition of the washing process is satisfied. As mentioned before, "Starting conditions of washing process", This is a condition that, for example, the value of the accumulated air-conditioning operation time has reached a predetermined value from the end of the previous cleaning process. In step S201, When the start condition of the washing process is satisfied (S201: Yes), The processing of the control unit K proceeds to step S202. on the other hand, When the start condition of the washing process is not satisfied (S201: No), The control unit K ends a series of processing (END).  [0044] In step S202, Control unit K, The notification sound generation unit 25 generates a predetermined notification sound, Or let the display lamp 26 light up. that is, The control unit K, before starting the washing process such as freezing of the indoor heat exchanger 12, The notification sound generation unit 25 and the display lamp 26 notify the intention to perform the cleaning process. With this, The user can be notified in advance of the start of the cleaning process.  [0045] Next, In step S203, The control unit K sets a delay time until the washing process of the indoor heat exchanger 12 is started (that is, Standby time). The delay time (for example, several seconds to several tens of seconds), Yes in step S202, The time required to notify the user in advance of the start of the cleaning process until the actual start of the cleaning operation, And it is preset.  [0046] In step S204, Control unit K, It is the intention to notify the user to start the washing process (S202) before proceeding to determine whether a predetermined delay time has passed. When the predetermined delay time has elapsed (S204: Yes), The process of the control unit K proceeds to step S205. Lighting of the display lamp 26 and the like may be continued until the delay time elapses (S202).  In step S205, The control unit K performs a cleaning process of the indoor heat exchanger 12 (S101 to S104 in FIG. 5).  [0047] On the other hand, When the predetermined delay time has not passed in step S204 (S204: No), The processing of the control unit K proceeds to step S206.  In step S206, Control unit K, It is determined by the operation of the remote control 40 or the portable terminal 50 whether or not there is a cancel instruction for the washing process. When there is no cancel instruction for the cleaning process (S206: No), The process of the control unit K returns to step S204. on the other hand, When there is a cancel command for cleaning processing (S204: Yes), The processing of the control unit K proceeds to step S207.  [0048] In step S207, Control unit K, The notification sound generation unit 25 generates a predetermined notification sound, Or let the display lamp 26 light up. With this, Can follow the operation of remote control 40, etc. The user is notified of the actual cancellation of the cleaning operation.  [0049] In addition, The aforementioned notification sound (S207), It is desirable to have a different type from the notification sound (S202) for the prior notice washing process. With this, This allows the user to easily understand that the washing process has actually been cancelled.  [0050] Then, In step S208, The control unit K cancels the cleaning process of the indoor heat exchanger 12. that is, Control unit K, In accordance with a signal from the remote control 40 or the portable terminal 50, the freezing and washing process including the indoor heat exchanger 12 is cancelled. In more detail, From the notification (S202) before the start of the washing process until a predetermined delay time (predetermined time) elapses When a predetermined cancellation instruction is received from the remote control 40 or the portable terminal 50 (S204: No, S206: Yes), The control unit K does not perform the freezing and washing process including the indoor heat exchanger 12 (S208). With this, The control unit K can follow the user's will, The cleaning process of the indoor heat exchanger 12 is appropriately cancelled. and, After performing the processing of step S208, The control unit K ends a series of processing (END).  [0051] <Effect> According to the first embodiment, Control unit K, Before the cleaning process of the indoor heat exchanger 12, The intention to perform the washing process is notified (S202). With this, After that, the user can be notified of the cleaning process in advance.  [0052] Again, When there is a cancellation instruction after a predetermined delay time from the prior notice of the cleaning process (S202) (S204: No, S206: Yes), The control unit K cancels the washing process (S208). With this, It is possible to avoid a situation where the washing process is performed against the user's intention. In other words, Following the will of the user, The indoor heat exchanger 12 is cleaned.  005 [0053] ≪Second Embodiment≫ Second Embodiment, The difference between the first embodiment and the first embodiment is a description of a process in which a cancel command is given in the cleaning process of the indoor heat exchanger 12 (see FIG. 2). In addition, Regarding other points (the structure of the air conditioner 100 shown in FIGS. 1 to 4, The flowchart of the washing process shown in Fig. 5) is the same as that of the first embodiment. therefore, A description will be given of parts different from the first embodiment. The description of the overlapping portions is omitted.  [0054] FIG. 7, It is a flowchart showing the process of the control part K in the washing process (refer to FIG. Figure 4).  In step S301, The control unit K determines whether or not a washing process is being performed. In addition, Regarding washing treatment, This is as described in the first embodiment (see FIG. 5).  [0055] In addition, Although omitted in FIG. 7, However, when the freezing and washing process including the indoor heat exchanger 12 is performed, The control unit K may also use the notification sound generating unit 25, The display lamp 26 notifies that the washing process is in progress. With this, It is easy for a user to grasp how the cleaning process of the indoor heat exchanger 12 is performed. and, For example, when the user does not want the washing process to continue, A predetermined cancellation instruction is transmitted to the indoor unit 10 by an operation of the remote controller 40 or the like.  [0056] In step S301 of FIG. 7, Currently in the washing process (S301: Yes), The processing of the control unit K proceeds to step S302. on the other hand, When no washing treatment is currently performed (S301: No), The control unit K ends the processing (END).  [0057] In step 302, Control unit K, It is determined by the operation of the remote control 40 or the portable terminal 50 whether or not there is a cancel instruction for the washing process. When there is no cancel instruction for the washing process (S302: No), After the control unit K continues the washing process, End a series of processing (END). on the other hand, When there is a cancel command for cleaning processing (S302: Yes), The processing of the control unit K proceeds to step S303.  [0058] Next, In step S303, The control unit K determines whether a predetermined time has elapsed from the start of the freezing of the indoor heat exchanger 12. This "scheduled time" (e.g. minutes), It is the time until the indoor heat exchanger 12 functioning as an evaporator is sufficiently cooled (the moisture contained in the air is cooled to the extent that the indoor heat exchanger 12 is cooled to a degree of freezing) And it is preset.  [0059] When a predetermined time has elapsed from the start of freezing of the indoor heat exchanger 12 in step S303 (S303: Yes), The processing of the control unit K proceeds to step S304. To be specific, Except for the case where the freezing of the indoor heat exchanger 12 deepens, Defrosting the indoor heat exchanger 12 (S103 in FIG. 5), When drying (S104 in Figure 5), The processing of the control unit K proceeds to step S304.  [0060] In step S304, Control unit K, The notification sound generation unit 25 generates a predetermined notification sound, The display lamp 26 is turned on again. With this, As described later, A person who has a cancellation instruction for the cleaning process (S302: Yes), especially, The user can be informed of the intention of the continuous washing process ("drying" in S305).  [0061] Next, In step S305, The control unit K dries the indoor heat exchanger 12. E.g, When more than a predetermined time elapses during freezing (S303: Yes), There is a possibility that ice adheres to the surface of the indoor heat exchanger 12. Let the water evaporate after the ice is dissolved at room temperature, Further drying (S305) can achieve antibacterial and antifungal effects.  Alas, Thawing of the indoor heat exchanger 12 (S303: Yes), The ice in the indoor heat exchanger 12 is dissolved, A part of it drips onto the drain pan 13 (see FIG. 2), The rest is attached to the indoor heat exchanger 12. Drying the adhered water (S305) can prevent bacteria and mildew.  Alas, Drying of the indoor heat exchanger 12 (S303: Yes), Let it dry (S305), And make the indoor heat exchanger 12 clean. [0062] So, From the start of the frozen washing process including the indoor heat exchanger 12 to the lapse of a predetermined time (S303: Yes), When a cancellation command for the washing process is received from the remote control 40 or the portable terminal 50 (S302: Yes), The control unit K causes the indoor heat exchanger 12 to dry (S305).  [0063] In addition, Regarding the processing content of step S305, This is the same as step S104 (see FIG. 5) described in the first embodiment. As an example, The control unit K performs a greenhouse operation (let the indoor heat exchanger 12 function as a condenser), The indoor heat exchanger 12 is allowed to dry.  [0064] Next, In step S306, The control unit K determines whether there is a cancellation command again. that is, After the control unit K cancels the reception of the command, During the drying of the indoor heat exchanger 12, It is determined whether a predetermined cancellation instruction is received from the remote controller 40 or the portable terminal 50 again.  [0065] When there is no cancel instruction again in step S306 (S306: No), The process of the control unit K returns to step S305. In this case, the drying of the indoor heat exchanger 12 is continued.   on the other hand, When there is a cancel instruction again in step S306 (S306: Yes), The processing of the control unit K proceeds to step S307.  [0066] In step S307, Control unit K, The notification sound generation unit 25 generates a predetermined notification sound, The display lamp 26 is turned on again. With this, Following the cancellation instruction of the washing process, the user can be notified of the actual suspension of the washing process (ie, Of the indoor heat exchanger 12) (S308).  [0067] In step S308, The control unit K stops the drying of the indoor heat exchanger 12. With this, Even in the drying of the indoor heat exchanger 12, It is also possible to appropriately reflect the intention of a user who wants to stop the processing. After the processing of step S308 is performed, The control unit K ends a series of processing (END).  [0068] Again, When a predetermined time has not elapsed from the start of freezing of the indoor heat exchanger 12 in step S303 (S303: No), The processing of the control unit K proceeds to step S309.  In step S309, Control unit K, The notification sound generation unit 25 generates a predetermined notification sound, The display lamp 26 is turned on again. With this, The user can be informed of the intention to stop the freezing of the indoor heat exchanger 12 (S310).  [0069] In step S310, The control unit K stops freezing of the indoor heat exchanger 12. at this time, Because there is almost no ice on the indoor heat exchanger 12, and so, Even if the freezing of the indoor heat exchanger 12 is stopped, there is no hindrance. that is, Hardly a lot of water adheres to the surface of the indoor heat exchanger 12 to generate bacteria, Moldy concerns.  [0070] So, Before a predetermined time elapses from the start of freezing of the indoor heat exchanger 12 (S303: No), When the aforementioned frozen cancel instruction is received from the remote control 40 or the portable terminal 50 (S302: Yes), The control unit K stops its freezing (S310). After performing the processing of step S310, The control unit K ends a series of processing (END).  [0071] <Effect> According to the second embodiment, When a cancellation instruction is received during the cleaning process of the indoor heat exchanger 12 (S302: Yes), When a predetermined time has elapsed from the start of freezing (S303: Yes), The control unit K also performs drying of the indoor heat exchanger 12 (S305). With this, Prevent a lot of water from adhering to the surface of the indoor heat exchanger 12, It has the effect of preventing bacteria and mildew.  [0072] Again, When a cancellation command is issued again during the drying of the indoor heat exchanger 12 (S306: Yes), The control unit K stops the drying of the indoor heat exchanger 12 (S308). With this, Even in the drying of the indoor heat exchanger 12, It is also possible to appropriately reflect the intention of a user who wants to stop the processing.  [0073] Again, When a cancellation instruction is received during the cleaning process of the indoor heat exchanger 12 (S302: Yes), When a predetermined time has not elapsed from the start of freezing (S303: No), The control unit K stops the freezing of the indoor heat exchanger 12 (S310). With this, The intention of the user who wants to cancel the washing process (freeze) can be appropriately reflected.  007 [0074] ≪Third embodiment ≫ Third embodiment, The point that is different from the first embodiment is that the processing when the operation instruction of the air-conditioning operation is received in the cleaning processing of the indoor heat exchanger 12 is described. In addition, Regarding other points (the structure of the air conditioner 100 shown in FIGS. 1 to 4, The flowchart of the washing process shown in Fig. 5) is the same as that of the first embodiment. therefore, A description will be given of parts different from the first embodiment. The description of the overlapping portions is omitted.  [0075] FIG. 8 shows a flowchart of the processing of the control unit K during or after the cleaning process (refer to FIG. Figure 4).  In step S401, The control unit K determines whether the air conditioning operation (warm room operation, warm room operation, Cold room operation, etc.). When an operation command for air-conditioning operation is received during the cleaning process (S401: Yes), The processing of the control unit K proceeds to step S403. at this time, There will be melting after the ice in the indoor heat exchanger 12 is frozen, Or the possibility that the thawed water adheres to the indoor heat exchanger 12. on the other hand, When no operation command for air-conditioning operation is received during the cleaning process (S401: No), The processing of the control unit K proceeds to step S402.  [0076] In step S402, The control unit K determines whether an operation instruction for the air-conditioning operation has been received within a predetermined time from the cancellation of the cleaning process of the indoor heat exchanger 12. When no operation instruction is received within a predetermined time from the cancellation of the washing process (S402: No), The control unit K ends a series of processing (END).  [0077] On the other hand, When an operation command is received within a predetermined time when the cleaning process is canceled (S402: Yes), The processing of the control unit K proceeds to step S403. at this time, In order to stop the washing process in the middle, There will be melting after the ice in the indoor heat exchanger 12 is frozen, It is possible to wet the surface of the indoor heat exchanger 12.  [0078] In step S403, Control unit K, The notification sound generation unit 25 generates a predetermined notification sound, The display lamp 26 is turned on again. With this, The user can be notified of the operation instruction of the air-conditioning operation.  [0079] In step S404, The control unit K stops (or suspends) the cleaning process of the indoor heat exchanger 12. that is, The control unit K includes the compressor 31, Each device of the indoor fan 14 is stopped.  In step S405, The control unit K determines whether a predetermined time has elapsed from when the washing process was stopped (or when it was suspended). The "scheduled time" Is to keep the stopped state of each machine, The time required for the indoor heat exchanger 12 to dry (to evaporate the moisture attached to its surface), And it is preset.  [0080] In step S405, When a predetermined time has elapsed from when the washing process was stopped (S405: Yes), The processing of the control unit K proceeds to step S406. on the other hand, When a predetermined time has not elapsed from when the washing process was stopped (S405: No), The process of the control unit K returns to step S404.  [0081] In step S406, The control unit K sets an execution time for drying the indoor heat exchanger 12. E.g, The control unit K, in order to dry the indoor heat exchanger 12, And set the execution time of greenhouse operation or air supply operation.  [0082] In step S407, The control unit K performs drying of the indoor heat exchanger 12. E.g, Control unit K, The indoor heat exchanger 12 is dried in a greenhouse operation or a ventilation operation. In addition, Can also be used for greenhouse operation, After that, a blower operation is performed to dry the indoor heat exchanger 12.  [0083] In step S408, The control unit K determines whether a predetermined execution time has elapsed from the start of the drying of the indoor heat exchanger 12 (set at S406). When the predetermined execution time has elapsed (S408: Yes), The process of the control unit K proceeds to step S409. at this time, Contains indoor heat exchanger 12, The interior of the indoor unit 10 is sufficiently dried.   on the other hand, When the predetermined execution time has not passed from the start of the drying of the indoor heat exchanger 12 (S408: No), The process of the control unit K returns to step S407.  [0084] Moreover, In step S409, The control unit K executes a predetermined air-conditioning operation in accordance with the operation instruction received in step S401 or S402. After performing the process of step S409, The control unit K ends a series of processing (END).  [0085] <Effect> According to the third embodiment, When an operation instruction is received from the cleaning process of the indoor heat exchanger 12 or a predetermined time when it is canceled (S401 or S402: Yes), The control unit K sequentially stops the washing process and the indoor heat exchanger 12 is dried (S404 to S408). The air-conditioning operation is executed (S409). With this, When an operation command for air-conditioning operation is received even when the indoor heat exchanger 12 is wet, After the inside of the indoor unit 10 is sufficiently dried, the air-conditioning operation may be performed.  00 [0086] ≪modified example≫ or more, Although the air conditioner 100 of the present invention is described in each embodiment, However, the present invention is not limited to such recorders, Various changes can be made.   E.g, In each embodiment, In terms of "washing treatment", Although the case where the indoor heat exchanger 12 is sequentially frozen, thawed, and dried is described (S102 to S104 in FIG. 5), But it is not limited to this. E.g, One or both of thawing and drying of the indoor heat exchanger 12 may be omitted. Even at this time, Since the indoor heat exchanger 12 is naturally thawed at room temperature, The indoor heat exchanger 12 can be washed by the water. also, Since the stop state of each machine can be continued, Subsequent air-conditioning operation, etc. The indoor heat exchanger 12 is dried.  [0087] Again, In each embodiment, Although the process of washing and cleaning the indoor heat exchanger 12 by freezing the indoor heat exchanger 12 will be described, But it is not limited to this. E.g, By allowing the indoor heat exchanger 12 to dew, The indoor heat exchanger 12 may be washed. at this time, Control unit K, Set the evaporation temperature of the refrigerant to be higher than that of a normal cold room. Dehumidification operation is lower. To be specific, Control unit K, Is based on the detection value of the indoor temperature sensor 21a (see FIG. 4), The dew point of the indoor air is calculated with the detection value of a humidity sensor (not shown). then, Control unit K, It is to adjust the opening degree of the outdoor expansion valve 34 and the like so that the temperature of the indoor heat exchanger 12 is below the aforementioned dew point, And becomes higher than the predetermined freezing temperature.  Additionally, The aforementioned "freezing temperature", When the temperature of indoor air is reduced, The temperature at which the moisture contained in the indoor air starts to freeze in the indoor heat exchanger 12. in this way, Let the indoor heat exchanger 12 dew, The indoor heat exchanger 12 can be washed by the dew condensation water.  [0088] Moreover, After the indoor heat exchanger 12 is allowed to dew, The control unit K dries the indoor heat exchanger 12. that is, When the indoor heat exchanger 12 is allowed to dew, Control unit K, Is to make the indoor heat exchanger 12 function as a condenser, Or perform a blower operation, The indoor heat exchanger 12 is allowed to dry.  [0089] Again, The control unit K can also be operated in a greenhouse, Cold room operation, Or freeze the indoor heat exchanger 12 after the dehumidification operation, Or condensation. With this, Can be operated in a greenhouse, Cold room operation, The indoor heat exchanger 12 is cleaned after an air-conditioning operation such as a dehumidification operation.  [0090] Again, In addition to the freezing of the indoor heat exchanger 12, Beyond condensation The indoor heat exchanger 12 may be cleaned by performing a cold room operation after the warm room operation. With this, Attach moisture to the indoor heat exchanger 12 cooled by the refrigerant, The indoor heat exchanger 12 is washed away with the moisture.  [0091] In addition, By the dew condensation of the indoor heat exchanger 12, The matters for cleaning the indoor heat exchanger 12 in the cold room operation after the warm room operation can be applied to the embodiments. in particular, As long as the condensation of the indoor heat exchanger 12 is performed, Or the cold room operation (after the warm room operation) can replace the processing of steps S102 (freezing) and step S103 (thawing) in FIG.  [0092] Again, In each embodiment, Although the processing of the scheduled notification regarding the air conditioner is described by the display lamp 26 and the like (see FIG. 4) of the indoor unit 10, But it is not limited to this.
