200813286 九、發明說明 【發明所屬之技術領域】 本發明是關於一種具備熱泵(heat pump )作爲使洗 衣槽內之衣服乾燥用的乾燥機構的洗衣機。 【先前技術】 由直接附設在承水槽的電熱器(electric heater)加熱 ,使貯留在承水槽內的自來水溫水化之構成的冼衣機,是 例如揭示在日本專利第 3330789號公報以及日本特開 2006-87484號公報。在此構成的情況下,由於是由電熱器 直接加熱承水槽,因此有承水槽的溫度會變高的問題。而 且,由於加熱器是暴露在多濕的環境,因此有會發生漏電 及短路(short-circuit)的問題。 【發明內容】 • [發明所欲解決之課題] 爲解決上述各問題點,可藉由利用熱泵系統(heat pump system )作爲熱源,使該熱栗的冷凝器及用以將自 來水注入承水槽的水管相互接觸,利甩冷凝器加熱水管內 的自來水而注入承水槽內。然而,在該構成的情況下,冷 凝器的熱會流失到自來水,因此會產生冷凝器不易升溫的 新問題。尤其當外部氣溫爲5 °C左右的低溫時,蒸發器會 變得容易結霜,因此朝向蒸發器及冷凝器的送風會因爲霜 而受到阻礙。所以,熱泵的運轉效率會大幅降低,因此冷 -5- 200813286 凝器的升溫會變得更爲困難。一般而言,水溫比常溫高 5 °C左右衣服的洗淨能力就會充分提高,但僅藉由冷凝器 加熱水管內的自來水的程度,要將「25L ( liter )〜30L」 量的自來水升溫至適合洗衣服的溫度是相當困難的。 本發明是鑒於上述情況而硏創者,其目的在於提供一 種可利用用以生成衣服之乾燥風的熱泵,使水溫升溫至適 合洗衣服的溫度的洗衣機。 [用以解決課題之手段] 本發明之洗衣機的特徵爲具備:可投入衣服的洗衣槽 :將前述洗衣槽收容成可旋轉狀態的承水槽;以前述承水 槽的內部空間分別作爲起點及終點,使前述承水槽內的空 氣朝一方向循環的送風機;具有壓縮機、從該壓縮機排出 的冷媒所流通的冷凝器、以及從壓縮機排出·的冷媒通過冷 凝器後所流通的蒸發器,並且加熱前述送風機所生成之循 • 環風的熱泵;用以將自來水注入前述承水槽內,並且以可 傳熱的方式連接於前述冷凝器的水管;可在不是通過前述 水管而將自來水注入前述承水槽內的第1注水狀態、將自 來水通過前述水管而注人前述承水槽內的第2注水狀態、 ^ 以及不將自來水注入前述承水槽內的注水停止狀態相互間 進行切換的閥機構;以及用以分別驅動前述送風機、前述 壓縮機及前述閥機構的控制電路;該控制電路係進行:使 前述閥機構形成前述第1注水狀態,不是通過前述水管而 將自來水注入前述承水槽內的冷水注水處理;在此冷水注 -6- 200813286 水處理停止後或是執行當中,分別使前述送風機及前述壓 縮機運轉,而將溫風注入前述承水槽內的溫風注入處理; 以及從前述溫風注入處理開始經過設定時間之後,使前述 閥機構形成前述第2注水狀態,將自來水通過前述水管而 注入前述承水槽內的溫水注入處理。 [發明之效果] B 本發明是使閥機構形成第1注水狀態,不是通過水管 而將常溫的自來水注入承水槽內。在此冷水注入處理—停止 後或是執行當中,分別使送風機及壓縮機運轉,而將溫風 注入承水槽內,使承水槽內的自來水加熱。在此狀態下, 吸收了承水槽內之水分的溼度高的空氣會從承水槽返回蒸 發器,並藉由蒸發器進行潛熱熱交换,因而水分會凝縮或 凝結。因此,即使是外部氣溫爲5 °C左右的低溫時,蒸發 器也不易結霜,因而得以抑制朝向蒸發器及冷凝器各個的 • 送風受霜阻礙的情況。因此,可抑制熱泵之運轉效率的降 低,使得冷凝器容易升溫。此溫風注入處理開始經過設定 時間之後,冷凝器的溫度會變得比溫風注入處理開始時高 很多,在冷凝器的溫度變得足夠高的時點,閥機構會被切 換成第2注水狀態,自來水便會通過水管而被注入承水槽 內。此溫水注入處理剛開始後,水管內的自來水會因爲吸 收冷凝器的熱容量而大幅升溫,因而吸收了冷凝器之熱容 量的高溫溫水會被注入承水槽內。因此,可將水溫升溫至 適合洗衣服的溫度。 200813286 【實施方式】 〈〈實施例1〉〉 在外箱1的內部是如第1圖所示,收納有複數個減震 器(damper) 2。在這複數個減震器2的桿(rod)固定有 承水槽3,承水槽3是經由複數個減震器2以制振狀態及 緩衝狀態收納在外箱1的內部。此'承水槽3是形成後面封 閉的有底圓筒狀,並且配置成軸心線CL從前方朝向後方 下降的傾斜狀態。在此承-7JC槽3的後板,是固定有位於承 水槽3的外部之滾筒馬達(drum-motor) 4的定子。此滾 筒馬達4,是由在定子(stator)的外周部配置轉子而構成 的外轉子型的DC無刷馬達(DC brushless motor)所構成 ,滾筒馬達4的旋轉軸是突出在承水槽3的內部。 在滾筒馬達4的旋轉軸固定有滾筒(drum ) 5。此滾 筒5相當於洗衣槽。當滾筒馬達4運轉時,會與滾筒馬達 #

CPU在步驟S2 1判斷承水槽3內的水位已到達水位之 -19- 200813286 設定結果時會前進至步驟S22。在此,將給水閥7從溫水 注水狀態切換成注水停止狀態,使自來水對於承水槽3內 的注入動作停止,並且前進至步驟S23的蒸發器溫度控制 處理。此步驟S23的蒸發器溫度控制處理是以與步驟S1 3 相同的內容,分別控制冷媒的流量及電子膨脹閥28的開 度,使蒸發器23的表面溫度Te位在設定範圍內。CPU從 步驟S23前進至步驟S24時,會根據計數器的計測値來判 斷是否已經過事先記.錄在_ ROM的循環停止時間(cycle outage time ) ° CPU在步驟S22判斷以停止注水動作爲基準經過循環 停止時間時,會從步驟S24前進至步驟S25。在此,使壓 縮機馬達25停止運轉,在步驟S26使風扇馬達21停止運 轉,在步驟S27將電子膨脹閥28調整成事先記錄在ROM 的開度(例如相當於400脈衝的開度),並且前進至步驟 S28 〇 CPU前進至步驟828時,會根據計數器的計測値來判 斷是否已經過事先記錄在ROM的溫水洗淨時間。此溫水 洗淨時間的經過是以在步驟S5開始滾筒馬達4之間歇運 轉爲基準來判斷。CPU判斷已經過溫水洗淨時間時,會從 步驟S2 8前進至步驟S29。在此,使滾筒馬達4停止運轉 ,結束溫水洗淨處理。 第7圖是第5圖之步驟S1〜步驟S29的溫水洗淨處理 的流程。此溫水洗淨處理是與冷水注水處理之開始同步使 滾筒5的間歇運轉開始,並將常溫的自來水注入滾筒5內 -20- 200813286 的洗滌衣物。在此冷水注水處理執行當中’風扇馬達2 1 及壓縮機馬達25分別是停止狀態,分割型冷凝器22、蒸 發器23及分割型冷凝器26分別是形成常溫狀態。 當冷水注水處理停止時,會在旁通閥3 0的閉鎖狀態 下,分別使風扇馬達21及壓縮機馬達25開始運轉,並將 溫風注入承水槽3內,使承水槽3內的水溫上升。此溫風 注入處理開始之後經過待機時間爲止的期間內,風扇馬達 2 1、壓縮機馬達25及電子膨服閥28分別是以既定的固定 條件運轉。在此開放控制期間內,分割型冷凝器22及分 割型冷凝器26各自的溫度會急遽上升,蒸發器23的溫度 會急遽下降。 溫風注入處理開始經過待機時間之後,會依蒸發器23 的表面溫度Te分別控觥壓縮機馬達25的運轉條件及電子 膨脹閥28的運轉條件。此反饋控制(feedback control) 會持續進行至風扇馬達21及壓縮機馬達25分別停止運轉 的循環運轉(cycle operation)結束爲止。在反饋控制期 間內,蒸發器23的表面溫度Te會被控制在目標範圍內, 反饋控制開始到溫水注水處理開始爲止的期間內,分割型 冷凝器22及分割型冷凝器26各自的溫度比起開放控制期 間會緩步地上升。 溫風注入處理開始到結束爲止的期間內,滾筒5內高 溫高濕的空氣會因爲蒸發器23而凝縮或凝結,空氣的溫 度可藉由該潛熱熱交換而成爲一定。因此,可防止蒸發器 23之異常的溫度降低,因而可抑制分割型冷凝器22及分 -21 - 200813286 割型冷凝器2 6各自的溫度降低。在此溫風注入處理執行 當中,當溫風溫度Tf到達基準値時,會使旁通閥3 0開放 。對此旁通閥3 0的切換時點設定限制時間。此限制時間 是設定成比溫水注入處理的開始時點還要早,在溫風溫度 Tf尙未到達基準値而經過限制時間時,會在溫水注入處理 開始前使旁通閥30開放。 在溫水注水處理當中,會從給水閥7通過水管1 0將 B 自來水注入承水槽3內。在此溫水注水處理剛開始前,分 割型冷凝器2 6的表面溫度會大幅上升,溫水注水處理剛 開始後,水管1 〇內的自來水會因爲吸收分割型冷凝器26 的熱容量而急遽地大幅升溫,分割型冷凝器26的溫度會 急遽下降。因此,從壓縮機24被排出的冷媒會繞過分割 型冷凝器22而集中流向分割型冷凝器26,因而分割型冷 凝器26的溫度可維持在下降位準。在此狀態下,水管10 內的自來水會從分割型冷凝器26之冷媒管27內的冷媒吸 • 收熱容量,並將對應於分割型冷凝器26之冷媒的溫度之 位準的溫水注入承水槽3內。此水管1 〇的內徑尺寸是被 設定得比冷水注水用的水管8小,溫水注水處理是將每單 位時間的注水量設定得比冷水注水處理還少。 CPU在第5圖的步驟S29結束溫水洗淨處理之後,會 依序執行步驟S3 0的排水處理及步驟S32的清洗處理。步 驟S 3 0的排水處理是將溫水洗淨處理中貯留在承水槽3內 的溫水排出至機外。CPU是使排水閥1 3開放而執行排水 處理。步驟S32的清洗處理是將對應於水位之設定結果的 -22- 200813286 量的自來水再度貯留在承水槽3內,並且使滾筒5內的洗 滌衣物落入不含洗滌劑成分的水中,將洗滌劑成分從洗滌 衣物加以去除。CPU在步驟S32的清洗處理當中會將排水 閥13從開放狀態切換成閉鎖狀態,並將給水閥7從注水 停止狀態切換成冷水注水狀態,然後將常溫的自來水從水 管8通過注水箱9注入承水槽3內,並藉由對滾筒馬達4 進行旋轉操作,使洗滌衣物落入水中。 B CPU結束步驟S32的清洗處理之後,會依序執行步驟 S33的排水處理及步驟S34的脫水處理。步驟S33的排水 處理是將在清洗處理當中貯留在承水槽3內的自來水排出 至機外。CPU是使排水閥1 3開放而執行排水處理。步驟 S 34的脫水處理是利用離心力使水分從滾筒5內的洗滌衣 物排出。CPU是使滾筒馬達4運轉而執行脫水處理。 CPU結束步驟S34的脫水處理之後,會依序執行步驟 S35的乾燥處理及步驟S36的冷卻處理。步驟S35的乾燥 Φ 處理是分別使滾筒馬達4、風扇馬達2 1及壓縮機馬達2 5 運轉,一面使滾筒5旋轉,一面對滾筒5內的洗滌衣物吹 送高溫低濕的乾燥風。在此乾燥處理當中,旁通閥3 〇是 被切換成閉鎖狀態,從壓縮機24排出的冷媒會分別在分 割型冷凝器22及分割型冷凝器26循環。步驟S36的冷卻 處理是分別使滾筒馬達4及風扇馬達21運轉,一面使滾 筒5旋轉,——面對滾筒5內的洗滌衣物吹送比乾燥風更低 溫的冷卻風。此冷卻風是並未藉由熱泵43進行熱交換的 常溫的風,用來使因爲步驟S35之乾燥處理而升溫的洗滌 -23- 200813286 衣物冷卻。 根據上述實施例,可發揮以下的效果。 使給水閥7形成冷水注水狀態,進行不是通過水管1 〇 而將常溫的自來水注入承水槽3內的冷水注水處理,在冷 水注水處理停止後,分別使風扇裝置4 1及壓縮機24運轉 ,以進行將溫風注入承水槽3內的溫風注入處理。在此溫 風注入處理當中,吸收了承水槽3內之水分的高溼度空氣 φ 會從承水槽3返回蒸發器23,並藉由蒸發器23進行潛熱 熱交換,使水分凝縮或凝結。因此,即使在外部氣溫爲 5 °C左右的低溫時,蒸發器也不容易結霜,因而可抑制朝 向蒸發器23及分割型冷凝器22各個的送風受霜阻礙的情 況。因此,可抑制熱泵43之運轉效率的降低,因而可分 別使分割型冷凝器22及分割型冷凝器26容易升溫。 從溫風注入處理開始1至過注水再開始時間的時點,分 割型冷凝器26的溫度會變得比溫風注入處理開始時高很 φ 多,在分割型冷凝器26之溫度變得足夠高的時點,將給 水閥7切換成溫水注水狀態,開始將自來水通過水管1 〇 而注入承水槽3內的溫水注入處理。在此溫水注入處理剛 開始_後,水管1 0內的自來水會因爲吸收分割型冷凝器2 6 的熱容量而大幅升溫,因此吸收了分割型冷凝器26之熱 容量的高溫的溫水就會被注入承水槽3內。因此’可使水 溫升溫至適合洗衣服的溫度,所以洗淨能力會提升。 本實施例是以蒸發器溫度感測器3 6之檢測結果會位 在既定的一定範圍內的方式’控制熱泵4 3之冷媒的流動 -24- 200813286 狀態。因此,分割型冷凝器22及分割型冷凝器26各個的 溫度會很快上升,爲了使承水槽3內之自來水溫水化的所 需時間得以縮短。而且,從蒸發器23返回壓縮機24之內 部的冷媒的溫度會變高,因此壓縮機24內之潤滑油的溫 度也會變高。因而得以減少冷媒在潤滑油中的溶解量,因 此得以抑制潤滑油稀釋度變化所造成之潤滑油之潤滑性能 降低。因此,可肪止零件在壓縮機24的內部無法順~利-動 φ 作的情況,所以可靠性會提升。 〈〈實施例2〉〉 在壓縮機24的排出口是如第8圖所示,連接有三方 閥45。此三方閥45是由電磁閥所構成的閥螺線管(valve solenoid)驅動。此三方閥45可在:使從壓縮機24排出 的冷媒分別流到分割型冷凝器26及分割型冷凝器22的注 水狀態、以及使從壓縮機24排出的冷媒不是流到分割型 # 冷凝器26而流到分割型冷凝器22的乾燥狀態相互間進行 切換。 _ 第9圖是設定爲溫水洗淨行程時之控制電路34的控 制內容。控制電—路3 4的CPU在承水槽3內貯留有注水中 # 斷水位之常溫的自來水時,會在步驟S7將給水閥7從冷 水注水狀態切換成注水停止狀態。接下來,在步驟S8會 將三方閥4 5切換成注水狀態,在步驟S 9會對電子膨脹閥 28的開度進行初期設定,在步驟S10會開始風扇馬達21 的定速運轉,在步驟S 1 1會開始壓縮機馬達2 5的定速運 -25- 200813286 轉。接下來,在三方閥45的注水狀態下執行步驟S12〜步 驟S34,在步驟S35的乾燥處理會將三方閥45從注水狀 態切換成乾燥狀態。因此,在步驟S12〜步驟S27的溫水 洗淨處理當中,冷媒會分別流到分割型冷凝器22及分割 型冷凝器26,在步驟S35的乾燥處理當中,冷媒不會流 到分割型冷凝器26,而是流到分割型冷凝器22,因此在 步驟S35的乾燥處理當中,用來使洗滌衣物乾燥的溫風的 p 生成效率會提高。 上述實施例2當中亦可爲:在步驟S35的乾燥處當中 ,分割型冷凝器22的溫度異常上升時,會將三方閥45從 乾燥狀態切換成注水狀態,將給水閥7從注水停止狀態切 換成溫水注水狀態,並藉由分割型冷凝器26進行熱交換 ,以使冷媒冷卻。 上述實施例1〜實施例2分別亦可使用管殼式冷凝器作 爲分割型冷凝器26。 〈〈實施例3〉〉 在主導管1 6的內部是如第1 〇圖所示,收納有波紋鰭 片式冷凝器50。此冷凝器50是在形成蛇行狀的一條冷媒 管的直線部相互間介設複數個鰭片,並且將複數個鰭片分 別接合在冷媒管的直線部而構成。第1 1圖(a )顯示出冷 凝器5 0的配管狀態。冷凝器5 0的冷媒管5 1是在左右方 向排列成四列。在此冷凝器50的複數個鰭片接合有形成 蛇行狀的一條水管5 2。此水管5 2是在左右方向排列成兩 -26- 200813286 列。水管52的內面是如第1 1圖(b )所示由平滑面所形 成。此水管5 2的各列是如第1 1圖(a)所示,介設於冷 媒管51的列相互間,並且經由冷凝器52的鰭片與冷媒管 51間接接觸。此水管5 2是如第1 〇圖所示,經由水管1〇 連接於給水閥7的加熱用輸出口,在給水閥7的溫水注水 狀態下,自來水可從水管10通過冷凝器50的水管52及 注水箱9而注入承水槽3內。 第1 2圖是設定爲溫水洗淨行程時之控制電路3 4的控 制內容。控制電路34的CPU在承水槽3內貯留有注水中 斷水位之常溫的自來水時,會在步驟S7將給水閥7從冷 水注水狀態切換成注水停止狀態。接下來,在步驟S 9會 對電子膨脹閥28的開度進行初期設定,在步驟si〇會開 始風扇馬達2 1的定速運轉,在步驟S 1 1會開始壓縮機馬 達25的定速運轉。判斷此壓縮機馬達25之定速運轉開始 後經過待機時間時,會從步驟S 1 2分別前進至步驟S 1 7及 φ 步驟S1 8,一面將蒸發器23的表面溫度Te控制在「· 5 °C〜〇 °C」的設定範圍內,一面等待注水再開始時間的經過 〇 CPU在步驟s 1 8判斷已經過注水再開始時間時,會前 進至步驟S 1 9。在此,將給水閥7從注水停止狀態切換成 溫水注水狀態,並將自來水從給水閥7的水管1 〇通過冷 凝器50的水管52及注水箱9注入承水槽3內。在此狀態 下,在水管5 2內的自來水及冷媒管5 1內的冷媒相互間會 進行熱交換’使水管5 2內的自來水受到加熱’因此溫度 -27- 200813286 比常溫更高的溫水會被注入承水槽3內(溫水注水)。此 冷凝器5 0的鰭片,爲了同時謀求加熱空氣的功能以及使 冷媒的熱從冷媒管5 1通過水管5 2傳到自來水的功能,是 設定在「〇 · 1 m m〜〇 · 1 5 m m」的範圍內。 根據上述實施例3,可發揮以下的效果。 從溫風注入處理開始經過注水再開始時間的時點,冷 凝器5〇的溫-度會變得比溫風注入處理開"始時高很多,在 _ 冷凝器5 0的溫度變得足夠高的時點,開始進行將給水閥7 切換成溫水注水狀態,將自來水通過水管5 2而注入承水 槽3內的溫水注入處理。在此溫水注入處理剛開始後,水 管52內的自來水會因爲吸收冷凝器50的熱容量而大幅升 溫,因此吸收了冷凝器50之熱容量的高溫的溫水會被注 入承水槽3內。因此,可使水溫升溫至適合洗衣服的溫度 ,因而洗淨能力會提升。 本實施例是利用冷凝器5 0生成溫水及溫風兩者的構 φ 成。因此,不需要使自來水溫水化的專用分割型冷凝器26 ,因而可實現省空間化(space-saving)及低成本化(cost reduction)。本實施例是將冷凝器50的水管52在左右方 向排列成兩列的構成。因此,水管52之展開狀態下的長 度尺寸會變短,因而將給水閥7從溫水注水狀態切換成注 水停止狀態時,水會利用虹吸效應(siphon effect )從水 管5 2內落下。因此,水不容易殘留在水管5 2內,因而可 肪止在水管5 2的內面發生結冰及生鏽。 本實施例之水管52內面是形成平滑面。因此,在水 -28- 200813286 管52之內面的一部分就不會有結冰所導致的應力集中的 情形,因而可防止水管5 2結冰而破裂的情況。而且’水 不會殘留在水管52的內面,因此’由此點也可防止水管 52之內面生鏽的情形。由於是使水管52的各列介設於冷 媒管5 1的列相互間,因此水管5 2內的自來水可從冷媒管 5 1內的冷媒有效吸收熱。而且,本實施例是使用波紋籍片 式(corrugated fin type )冷凝器作爲冷凝器5 0。因此’ φ 經由冷媒管5 1及水管52相互間的鰭片的熱傳導率會提升 ,因而可在冷媒管51內的冷媒及水管52內的自來水相互 間有效地進行熱交換。 〈〈實施例4 >〉 在壓縮機24的排出口是如第13圖所示,固定有相當 於本發明壓縮機溫度感測器的壓縮機溫度感測器( compressor temperature sensor ) 55,控制電路 34 是 根據 • 從壓縮機溫度感測器55輸出的溫度信號來檢測壓縮機24 之排出口的排出口溫度Tr。在冷凝器50固定有相當於本 發明冷凝器溫度感測器的冷凝器溫度感測器(condenser temperature sensor) 56,控制電_路34是根據從冷凝器溫 ^ 度感測器56輸出的溫度信號來檢測冷凝器50的表面溫度[Technical Field] The present invention relates to a washing machine including a heat pump as a drying mechanism for drying clothes in a laundry tank.

Moreover, since the heater is exposed to a humid environment, there is a problem of leakage and short-circuit. SUMMARY OF THE INVENTION [Problems to be Solved by the Invention] In order to solve the above problems, a condenser of a hot pump and a taper for injecting tap water into a water receiving tank can be used by using a heat pump system as a heat source. The water pipes are in contact with each other, and the condenser heats the tap water in the water pipe and injects into the water receiving tank. However, in the case of this configuration, the heat of the condenser is lost to the tap water, so that a new problem that the condenser does not easily heat up is generated. Especially when the outside air temperature is low at around 5 °C, the evaporator becomes easy to frost, so the air supply to the evaporator and the condenser is hindered by the frost. Therefore, the operating efficiency of the heat pump is greatly reduced, so the temperature rise of the cold-5-200813286 condenser becomes more difficult. In general, the washing power of the clothes is increased by about 5 °C higher than the normal temperature, but the tap water of "25L (liter) ~ 30L" is only used to heat the tap water in the water pipe by the condenser. It is quite difficult to warm up to a temperature suitable for washing clothes. The present invention has been made in view of the above circumstances, and an object thereof is to provide a washing machine which can use a heat pump for generating dry air of clothes to raise the temperature of the water to a temperature suitable for washing clothes. [Means for Solving the Problem] The washing machine of the present invention is characterized in that it includes a washing tank into which clothes can be placed: a receiving tank that accommodates the washing tank in a rotatable state; and an internal space of the water receiving tank as a starting point and an end point, respectively An air blower that circulates air in the water receiving tank in one direction; a condenser that has a compressor, a refrigerant that is discharged from the compressor, and an evaporator that flows through the condenser and passes through the condenser, and heats a heat pump according to the air blower generated by the air blower; a water pipe for injecting tap water into the water receiving tank and connected to the condenser in a heat transfer manner; and the tap water may be injected into the water tank not through the water pipe a first water injection state in the inside, a valve mechanism in which the tap water is injected into the water receiving tank through the water pipe, and a valve mechanism that switches between the water injection stop states in which the tap water is not injected into the water receiving tank; and Driving a control circuit of the air blower, the compressor, and the valve mechanism, respectively; the control circuit And performing the cold water injection treatment in which the valve mechanism is formed in the first water injection state, and the tap water is not injected into the water receiving tank by the water pipe; after the water treatment is stopped, or after the water treatment is stopped, the foregoing a blower and the compressor are operated to inject warm air into the water receiving tank; and after the set time elapses from the warm air injection processing, the valve mechanism is formed in the second water injection state, and the tap water is passed through the The water pipe is injected into the warm water injection treatment in the aforementioned water receiving tank. [Effects of the Invention] B In the present invention, the valve mechanism is formed into the first water injection state, and the tap water of normal temperature is not injected into the water receiving tank by the water pipe. After the cold water injection treatment, after the stop or during the execution, the blower and the compressor are respectively operated, and the warm air is injected into the water receiving tank to heat the tap water in the water receiving tank. In this state, the air having a high humidity which absorbs the moisture in the water receiving tank returns to the evaporator from the water receiving tank, and the latent heat exchange is performed by the evaporator, so that the moisture condenses or condenses. Therefore, even when the outside air temperature is low at about 5 °C, the evaporator is less likely to be frosted, and thus it is possible to suppress the air supply from being blocked by the evaporator and the condenser. Therefore, the reduction in the operating efficiency of the heat pump can be suppressed, so that the condenser is easily heated. After the warm air injection process starts to elapse after the set time, the temperature of the condenser becomes much higher than the start of the warm air injection process, and when the temperature of the condenser becomes sufficiently high, the valve mechanism is switched to the second water injection state. The tap water is injected into the water receiving tank through the water pipe. Immediately after the warm water injection treatment, the tap water in the water pipe is greatly heated by the heat capacity of the absorption condenser, so that the high temperature warm water that absorbs the heat capacity of the condenser is injected into the water receiving tank. Therefore, the temperature of the water can be raised to a temperature suitable for washing clothes. 200813286 [Embodiment] <Example 1> In the inside of the outer casing 1, as shown in Fig. 1, a plurality of dampers 2 are housed.

The water supply valve 7 is driven by a water supply valve motor I (refer to FIG. 3) composed of a pulse motor, and can be in a state of cold water injection, warm water injection, and water injection stop depending on the amount of rotation of the water supply valve motor 11. Switch. The cold water injection state is a state in which the input port and the cold water outlet are respectively opened, and the warm water outlet is closed. This cold water injection state is equivalent to the first water injection state. In the cold water injection state, as shown in Fig. 2, tap water is supplied from the cold water outlet to the water injection tank 9 through the water pipe 9. The warm water injection state is a state in which the input port and the warm water outlet are opened, respectively, and the cold water outlet is closed. This warm water injection state is equivalent to the second water injection state. In the case of warm water injection, tap water is supplied from the warm water outlet to the water filling case 9 through the water pipe 1 . The water injection stop state is a state in which the input port is closed, and the tap water is not supplied to the water tank 9 in the water stop state. As shown in Fig. 1, the water injection tank 9 is housed in the outer casing 1 where the 200813286 portion is higher than the water receiving tank 3. The tap water supplied from the cold water outlet of the water supply valve 7 to the water injection tank 9 and the tap water supplied from the warm water outlet of the water supply valve 7 to the water injection tank 9 are respectively injected into the water receiving tank 3 from the water injection tank 9. In the water receiving tank 3, as shown in Fig. 1, a drain pipe 〖2 is connected, and a drain valve 〖3 is placed in the drain pipe 12. This drain valve 〖3 is driven by a drain solenoid valve ι4 (refer to Fig. 3) which is composed of an electromagnetic solenoid. The drain valve 〗 3 will form a closable state in which the drain solenoid valve 14 is turned off to form a lockable state in which the water in the water receiving tank 3 cannot be discharged, and the drain solenoid valve 14 is turned on. The open state of the water in the sink 3. In the drain pipe 12, as shown in Fig. 2, the drain port 15 is connected. In the open state of the drain valve port 3, the water in the water receiving tank 3 is discharged from the drain pipe 12 through the drain port 15 to The outside of the outer casing 1 is as shown in Fig. 1, and a main duct 16 is housed below the water receiving tank 3. This main duct 16 extends straight toward the front and rear Φ. A lower end portion of the front duct 17 is connected to the front end portion of the main duct 16, and a lower end portion of the rear duct (r e a r d u c t ) 18 is connected to the rear end portion of the main duct 16. Thereafter, the upper end portion of the duct 18 is connected to the water receiving tank 3 from the rear, and the upper end portion of the front duct 17 is connected to the water receiving tank 3 from the front, and the main duct 16, the front duct 17, and the rear duct 18 are three components. A closed loop-shaped circulation air passage 19 is used as a starting point and an end point in the internal space of the drum 5, respectively. In the inside of the main duct 16 as shown in Fig. 1, a fan 20 is housed in the rear end portion, and the fan 20 is a rotating shaft connected to a fan motor (fan motor -10- 200813286) 21. This fan motor 21 is disposed outside the circulation air passage 19. When the fan motor 21 is operated, as shown by the arrow symbol in Fig. 1, the internal gas of the drum 5 flows from the inside of the front duct 17 toward the inside of the main duct 16, and after flowing inside from the front toward the rear inside the main duct 16, The inside of the drum 5 is returned to the inside through the rear duct 18. This fan motor 2 1 is composed of a D C brushless motor of controllable speed. The flow rate of the air circulating inside the circulation air path 19 can be adjusted by controlling the speed of the fan motor 2 1 . The fan motor 2 1 and the wind mouse 20 constitute a fan device (fan e quipment) 4 1, and the fan device 4 1 corresponds to a blower. In the inside of the main duct 16, as shown in Fig. 1, a split condenser 22 is housed in front of the fan 20, and an evaporator 23 is accommodated in front of the split condenser 22. In the operating state of the fan motor 21, the inside_gas of the drum 5 is supplied to the split condenser 22 via the evaporator 23. The evaporator 23 and the split condenser 22 are connected in series between the discharge port and the suction port of the compressor 24 φ as shown in Fig. 2 . The compressor 24 is housed inside the outer casing 1 outside the circulation air passage 19 as shown in Fig. 1 . The compressor motor 25 (see Fig. 3) is used as a drive source. This compressor motor 25 is composed of a DC brushless motor that can be speed controlled. The flow rate of the refrigerant discharged from the compressor 24 can be adjusted by controlling the speed of the compressor motor 25. This compressor 24 corresponds to the compressor of the present invention. The evaporator 23 corresponds to the evaporator of the present invention. In the inside of the outer casing 1, as shown in Fig. 2, a split type condenser 26 located outside the circulation air passage 19 is housed. The split type condenser 26 is a fin type 11 - 200813286 (plate fin type), and a plurality of heat radiating fins are joined in contact with each other to form a serpentine refrigerant tube 27 (refer to Fig. 4). The condenser 26 constitutes a condenser 42 corresponding to the condenser in the same manner as the split condenser 22 (see Fig. 2). The refrigerant pipe 27 of the split condenser 26 is connected between the split condenser 22 and the evaporator 23 as shown in Fig. 2 . In the refrigerant pipe 27 of the split type condenser 26, the water pipe 1 is joined (welded) in a state in which the crucibles are in parallel contact as shown in Fig. 4, and the refrigerant flowing through the cold coal pipe H 27 and the tap water flowing through the water pipe 1 are mutually exchanged. Heat exchange is possible. That is, the water pipe 10 is configured to be in direct contact with the condenser 42. The water pipe 8 is configured to be separated from the condenser 42. As shown in Fig. 2, the evaporator 23 and the split condenser 26 are interposed therebetween, and an electronic expansion valve 28 is interposed. The electronic expansion valve 28 is operated by the expansion valve motor 29 (see Fig. 3) to decompress the refrigerant and expand the volume of the refrigerant. The expansion valve motor 29 is constituted by a pulse motor capable of position control, and the opening degree of the electronic expansion valve 28 can be adjusted according to the amount of rotation of the expansion valve motor 29. In the inner portion of the outer casing 1, as shown in Fig. 2, a bypass valve (b y p a s v a 1 v e ) 30 is accommodated outside the circulation air passage 19. The bypass valve 30 is driven by a bypass valve solenoid 31 (see Fig. 3) constituted by a solenoid valve, and is switchable between an open state and a closed state. As shown in FIG. 2, the bypass valve 30 is connected in parallel to the split condenser 22, and is a normal path for circulating the refrigerant to the split condenser 26 via the split condenser 22 and bypassing the refrigerant. The bypass path of the split condenser 22 to the split condenser 26 is switched between -12 and 200813286. The bypass valve 30, the evaporator 23, the compressor 24, the condenser 42, and the electronic expansion valve 28 constitute a heat pump 43. In the front panel of the outer casing 1, as shown in Fig. 1, a control panel 32 is fixed, and a plurality of switches 33 (see Fig. 3) operable from the front are attached to the operation panel 32. Inside the outer casing 1, a control circuit 34 (micrograph) mainly composed of a microcomputer is housed (see Fig. 3). The control circuit 34 has a CPU, a ROM, a RAM, and a clock circuit. The control circuit 34 sets the operation contents according to the operation contents of the plurality of switches 3 3, and drives the drum motor 4, the water supply valve motor 1 1 , the drain solenoid valve 14 , the fan motor 21 , and the compression according to the setting result of the operation contents. The machine motor 25, the expansion valve motor 29, and the bypass solenoid valve 3 1 thereby automatically perform the laundry operation including the drying step. The sump water tank 3 is connected to a pressure sensor 35 via an air-tube (refer to Fig. 3). This vent pipe will transfer the internal pressure of the water receiving tank 3 to the pressure sensor 35. The pressure sensor 35 outputs a pressure signal corresponding to the internal pressure level of the water receiving tank 3. The control circuit 34 detects the water level in the water receiving tank 3 based on the pressure signal from the pressure sensor 35. An evaporator temperature sensor 36 is joined to the evaporator 23 (refer to Fig. 3). The control circuit 34 detects the surface temperature of the evaporator 23 based on the temperature signal output from the evaporator temperature sensor 36. Inside the rear duct 18, a warm air temperature sensor 40 is attached to the upper end portion (refer to FIG. 3), and the control circuit 34 senses the temperature from the temperature of the warm air - 13 - 2008 13 286 40 The output temperature signal detects the temperature of the wind discharged from the rear duct 18 into the water receiving tank 3. A position sensor 37 is fixed to the stator of the drum motor 4 (refer to Fig. 3). This position sensor 37 detects the rotor magnet of the drum motor 4 to output a position signal. The control circuit 34 detects the rotational speed of the drum motor 4 based on the position signal from the position sensor 37. A position sensor φ 3 8 is fixed to the stator of the fan motor 21 (refer to Fig. 3). This position sensor 38 detects the rotor magnet of the fan motor 21 and outputs a position signal. The control circuit 34 detects the rotational speed of the fan motor 21 based on the position signal from the position sensor 38. A position sensor 39 is fixed to the stator of the compressor motor 25 (refer to Fig. 3). This position sensor 39 detects the rotor magnet of the compressor motor 25 and outputs a position signal. The control circuit 34 detects the rotational speed of the compressor motor 25 based on the position signal from the position sensor 39. Fig. 5 is a control content of the control circuit 34 when it is set to a warm water washing course. This warm water washing stroke can be set by the CPU of the control circuit 34 in accordance with the operation contents of the plurality of switches 33. In the setting state of the warm water washing stroke, the CPU determines whether or not there is an operation start command in step S1 of Fig. 5 . This operation start command can be judged based on the operation contents of the plurality of switches 3 3 . For example, when the user puts the laundry into the drum 5, puts the detergent into the water tank 9, and operates the plurality of switches 33 with a predetermined content, the CPU determines that there is an operation start command in step S1 and proceeds to step S2. When the CPU proceeds to step S2, it determines the weight of the laundry which is put into the drum 5 and is washed. The weight of the laundry can be rotated by a certain amount of time previously recorded in the ROM and recorded in the ROM for a certain period of time, and the drum motor 4 is rotated in a certain direction, and the time change rate of the rotation speed of the drum motor 4 is detected. It is judged to be of high weight, medium weight, and low weight. After the CPU determines the weight of the laundry in step S2, the water level is set in step S3. This water level can be set according to the judgment result of the weight of the laundry. When the laundry is high in weight, it will be set to a high water level, and the washing will be set to the middle water level when the laundry is medium weight, and will be set to the low water level when the laundry is low weight. After the CPU sets the water level in step 3, the drain solenoid valve 14 is closed (OFF) in step S4 to close the drain valve 13, and the water supply valve motor 1 is driven to make the water supply valve 7 form a cold water injection state. In this state, the tap water is supplied from the water pipe 8 to the water injection tank 9, and the tap water is injected into the water receiving tank 3 from the water injection tank 9 together with the detergent in the water injection tank 9. This step S4 is equivalent to cold water injection. • After the CPU starts the cold water filling process in step S4, the intermittent operation of the drum motor 4 is started in step S5. This intermittent operation is performed at a certain time interval: the rotation operation of the drum motor 4 is performed only at a certain required time in a certain rotation direction in a certain rotation direction. The laundry in the drum 5 is uniformly injected from the water injection tank 9 with tap water containing a detergent component. When the CPU starts the intermittent operation of the drum motor 4 in step S5, the CPU proceeds to step S6. Here, the water level in the water receiving tank 3 is detected based on the pressure signal from the pressure sensor 35, and the water level detection result is compared with the water injection interruption water level (for example, 12L) recorded in the ROM in advance -15-200813286. This water injection interrupt water level is set to be lower than the lowest low water level. When the CPU determines that the water level detection result has reached the water injection interruption water level, the CPU proceeds to step S7. Here, the water supply valve 1 is driven to switch the water supply valve 7 from the cold water injection state to the water injection stop state, and the tap water injection operation at the normal temperature is interrupted. When C P U interrupts the water injection operation of the tap water at normal temperature in step S7, the bypass solenoid valve 31 is closed (OFF) at φ step S8 to close the bypass valve 30. Next, it proceeds to step S9, and the expansion valve motor 29 is driven to set the opening degree of the electronic expansion valve 28 to the initial value. This electronic expansion valve 28 supplies a drive signal of 420 pulses/second to the expansion valve motor 29 to set the opening to the upper limit 値. The initial opening degree of the electronic expansion valve 28 of the step S9 is set to "200 pulses / 420 pulses". After the CPU initially sets the opening degree of the electronic expansion valve 28 in step S9, the constant speed operation of the fan motor 21 is started in step S10. This wind/fan motor 21 is maintained at a constant speed recorded in advance in the ROM after the fan motor 21 is accelerated in the start mode of the ROM. In the operating state of the fan motor 21, the internal gas of the drum 5 is returned to the drum 5 through the evaporator 23 and the split condenser 22, respectively. ^ After the CPU starts the constant speed operation of the fan motor 21 in step S10, the constant speed operation of the compressor motor 25 is started in step S11. The constant speed operation of the compressor motor 25 is maintained at a constant speed (e.g., 70 Hz) previously recorded in the ROM after the compressor motor 25 is accelerated in the startup mode previously recorded in the ROM. In the operating state of the compressor motor 25, the refrigerant -16-200813286 circulates in the sequence in the split condenser 22, the split condenser 26, the electronic expansion valve 28, and the evaporator 23, and the evaporator 23 causes the drum 5 to The internal gas is cooled, the moisture is removed from the internal gas, and the split condenser 22 heats the cold air to raise the temperature. Therefore, the high-temperature, low-humidity air is sent to the drum 5, so the tap water in the drum 5 is heated and heated. After the CPU starts the constant speed operation of the compressor motor 25 in step S11, it is determined in step S12 that the step S1 2 is φ or not, and the standby time (for example, 5 minutes) that has been previously recorded in the ROM is determined based on the measurement of the counter. . This counter is based on the CPU detecting the clock signal from the clock circuit and updating by interrupt processing. When the CPU judges that the standby time has elapsed from the start of the constant speed operation of the compressor motor 25 in step S11, it proceeds from step S1 2 to the evaporator temperature control process of step S13. The evaporator temperature control process controls the flow rate of the refrigerant and the opening degree of the electronic expansion valve 28, respectively, so that the surface temperature of the evaporator 23 is within the set range. The fan motor 21, the compressor motor 25, and the electronic expansion valve 28 are operated under fixed conditions during the period from the start of the operation of the heat pump 43 to the standby time. Fig. 6 is a detail of the evaporator temperature control process of step S13. The CPU detects the surface temperature Te of the evaporator 23 based on the temperature signal from the evaporator. temperature sensor 36 in step S41 of Fig. 6, and records the detection result of the surface temperature Te with the lower reference 事先 previously recorded in the ROM ( For example, -5 °C) for comparison. When it is judged as "Te S lower reference 値", the process proceeds to step S42, and the number of revolutions of the compressor motor 25 is reduced from the current speed to the unit 事 previously recorded in the ROM. Next, the process proceeds to step S43, and the opening degree of the electronic expansion valve 28 of -17-200813286 is increased from the current opening degree only by the unit 事先 previously recorded in the ROM. When the CPU proceeds to step S44, the surface temperature Te of the evaporator 23 is detected based on the temperature signal from the evaporator temperature sensor 36, and the detection result of the surface temperature Te is recorded in advance on the upper reference point of the ROM (for example, 〇°). C) Compare. When it is judged as "Te 2 upper reference 値", the process proceeds to step S45, and the number of revolutions of the compressor motor 25 is previously recorded in the unit ROM of the ROM from the current speed by only φ. Next, the process proceeds to step S46, and the opening degree of the electronic expansion valve 28 is reduced from the current opening degree to the unit 事先 previously recorded in the ROM. That is, when the surface temperature Te of the evaporator 23 drops below the lower reference enthalpy, the flow rate of the refrigerant will decrease from the current enthalpy, and the opening degree of the electronic expansion valve 28 will become larger from the present enthalpy, so the surface temperature of the evaporator 23 Te will rise. Further, when the surface temperature Te of the evaporator 23 rises above the upper reference enthalpy, the flow rate of the refrigerant increases from the current enthalpy, and the opening degree of the electronic expansion valve 28 becomes small, so that the surface temperature Te of the evaporator 23 is lowered by Φ. In short, the CPU controls the flow state of the refrigerant of the heat pump 43, so that the temperature signal from the evaporator temperature sensor 36 is within a predetermined range. When the CPU proceeds to step s 1 4 of FIG. 5, the warm air temperature Tf discharged into the drum 5 is detected based on the temperature signal from the warm air temperature sensor 40, and the detection result of the warm air temperature Tf is detected. Compare with the benchmark 事先 recorded in advance in the ROM. When it is judged as "Tfg reference 値" here, the process proceeds to step S1 6, and the bypass valve 30 is switched from the locked state to the open state. The CPU determines in step S14 that "the warm air temperature is only When <reference 値", -18-200813286 judges whether or not the valve switching time previously recorded in the ROM has been passed based on the measurement of the counter in step S15. This valve switching time is set to 1 /2 of the water injection restart time of step S18, for example, 10 minutes. When the CPU determines that the valve switching time has elapsed based on the start of the constant speed operation of the compressor motor 25 in step S11, the CPU proceeds from step S15 to step S16 to switch the bypass valve 30 from the closed state to the open state. After the CPU opens the bypass valve 30 in step S16, it proceeds to the evaporator temperature control process of step S1. The evaporator temperature control process of this step S17 is the same as that of step S13, and the flow rate of the refrigerant and the opening degree of the electronic expansion valve 28 are controlled by S!J so that the surface temperature Te of the evaporator 23 is at Within the setting range. When the CPU proceeds from step S17 to step S18, it is judged based on the measurement 计数器 of the counter whether or not the water injection restart time (for example, 20 minutes) previously recorded in the ROM has been passed. When the CPU judges that the water injection restart time has elapsed in step S11 to start the constant speed operation of the compressor motor 25, it proceeds from step S1 8 to step S1 9. Here, the water supply valve 7 is switched from the water injection stop state to the warm water injection state, and the tap water is started to be injected into the water tank 3 from the water pipe 1 through the water injection tank 9, and the process proceeds to the evaporator temperature control process of step S20. The evaporator temperature control process in this step S20 is to control the flow rate of the refrigerant and the opening degree of the electronic expansion valve 28 in the same manner as in the step S13, so that the surface temperature Te of the evaporator 23 is within the set range. When the CPU proceeds from step S20 to step S21, the water level in the water receiving tank 3 is detected, and the detection result of the water level is compared with the setting result of the water level in step S3. When the CPU determines in step S2 1 that the water level in the water receiving tank 3 has reached the water level -19-200813286 setting result, it proceeds to step S22. Here, the water supply valve 7 is switched from the warm water injection state to the water injection stop state, the tap water is stopped for the injection operation in the water receiving tank 3, and the process proceeds to the evaporator temperature control process of step S23. The evaporator temperature control process of this step S23 is to control the flow rate of the refrigerant and the opening of the electronic expansion valve 28, respectively, in the same manner as in the step S13, so that the surface temperature Te of the evaporator 23 is within the set range. When the CPU proceeds from step S23 to step S24, it is judged based on the measurement 计数器 of the counter whether or not the cycle outage time recorded in the _ROM has been recorded. The CPU judges in step S22 that the water injection operation is stopped as a reference. When the cycle stop time is reached, the process proceeds from step S24 to step S25. Here, the compressor motor 25 is stopped, the fan motor 21 is stopped in step S26, and the electronic expansion valve 28 is adjusted to be previously recorded in the opening degree of the ROM (for example, equivalent to 400 pulses) in step S27, and Proceeding to step S28, when the CPU proceeds to step 828, it is judged based on the measurement 计数器 of the counter whether or not the warm water washing time previously recorded in the ROM has elapsed. This warm water washing time is judged by starting the intermittent operation of the drum motor 4 in step S5. When the CPU judges that the warm water washing time has passed, it proceeds from step S2 to step S29. Here, the drum motor 4 is stopped, and the warm water washing process is terminated. Fig. 7 is a flow chart of the warm water washing process in steps S1 to S29 of Fig. 5. This warm water washing treatment starts the intermittent operation of the drum 5 in synchronization with the start of the cold water water injection treatment, and injects tap water of normal temperature into the washing clothes in the drum 5 -20-200813286. In the execution of the cold water water injection process, the fan motor 2 1 and the compressor motor 25 are in a stopped state, and the split condenser 22, the evaporator 23, and the split condenser 26 are each formed in a normal temperature state. When the cold water water injection treatment is stopped, the fan motor 21 and the compressor motor 25 are started to operate in the locked state of the bypass valve 30, and the warm air is injected into the water receiving tank 3 to heat the water in the water receiving tank 3. rise. During the period from the standby time after the start of the warm air injection process, the fan motor 21, the compressor motor 25, and the electronic expansion valve 28 are operated under predetermined fixed conditions. During this open control period, the temperature of each of the split condenser 22 and the split condenser 26 rises sharply, and the temperature of the evaporator 23 drops sharply. After the warm air injection process starts to pass the standby time, the operating conditions of the compressor motor 25 and the operating conditions of the electronic expansion valve 28 are controlled depending on the surface temperature Te of the evaporator 23, respectively. This feedback control continues until the end of the cycle operation in which the fan motor 21 and the compressor motor 25 are stopped. During the feedback control period, the surface temperature Te of the evaporator 23 is controlled within the target range, and the temperature ratio of the split condenser 22 and the split condenser 26 during the period from the start of the feedback control to the start of the warm water injection process. It will rise slowly during the period of open control. During the period from the start of the warm air injection treatment to the end, the high-temperature and high-humidity air in the drum 5 is condensed or condensed by the evaporator 23, and the temperature of the air can be made constant by the latent heat exchange. Therefore, the abnormal temperature drop of the evaporator 23 can be prevented, so that the temperature drop of each of the split condenser 22 and the split type condenser 26 can be suppressed. During the execution of the warm air injection process, when the warm air temperature Tf reaches the reference enthalpy, the bypass valve 30 is opened. A limit time is set for the switching timing of the bypass valve 30. The time limit is set earlier than the start of the warm water injection process, and when the warm air temperature Tf 尙 does not reach the reference 値 and the time limit elapses, the bypass valve 30 is opened before the warm water injection process starts. In the warm water injection treatment, B tap water is injected into the water receiving tank 3 from the water supply valve 7 through the water pipe 10. Before the warm water injection treatment is started, the surface temperature of the split condenser 26 will rise sharply. After the warm water injection treatment is started, the tap water in the water pipe 1 will be rushed by the heat capacity of the split condenser 26. When the temperature rises drastically, the temperature of the split condenser 26 is drastically lowered. Therefore, the refrigerant discharged from the compressor 24 is bypassed by the split condenser 22 and concentrated to the split condenser 26, so that the temperature of the split condenser 26 can be maintained at the falling level. In this state, the tap water in the water pipe 10 absorbs the heat capacity from the refrigerant in the refrigerant pipe 27 of the split type condenser 26, and injects warm water corresponding to the temperature of the refrigerant of the split type condenser 26. Inside the sink 3. The inner diameter of the water pipe 1 is set smaller than the water pipe 8 for cold water injection, and the warm water injection treatment sets the water injection amount per unit time to be less than the cold water injection treatment. After the CPU finishes the warm water washing process in step S29 of Fig. 5, the draining process of step S30 and the washing process of step S32 are sequentially performed. The draining treatment in the step S30 is to discharge the warm water stored in the water receiving tank 3 in the warm water washing treatment to the outside of the machine. The CPU performs the drain treatment by opening the drain valve 13 . The cleaning process in step S32 is to store the tap water in the amount of -22-200813286 corresponding to the setting result of the water level in the water receiving tank 3, and to cause the laundry in the drum 5 to fall into the water containing no detergent component, and to wash the detergent. The ingredients are removed from the laundry. The CPU switches the drain valve 13 from the open state to the closed state during the cleaning process of step S32, and switches the water supply valve 7 from the water injection stop state to the cold water injection state, and then injects the normal temperature tap water from the water pipe 8 through the water injection tank 9. In the water tank 3, the washing clothes are dropped into the water by rotating the drum motor 4. After the B CPU ends the cleaning process of step S32, the drain process of step S33 and the dehydration process of step S34 are sequentially performed. The draining treatment in the step S33 is to discharge the tap water stored in the water receiving tank 3 during the washing process to the outside of the machine. The CPU opens the drain valve 13 to perform a drain process. The dehydration treatment in step S 34 is to discharge moisture from the laundry in the drum 5 by centrifugal force. The CPU operates the drum motor 4 to perform a dehydration process. After the CPU ends the dehydration process of step S34, the drying process of step S35 and the cooling process of step S36 are sequentially performed. In the drying Φ process of step S35, the drum motor 4, the fan motor 2 1 and the compressor motor 25 are respectively operated to rotate the drum 5, and a dry wind having a high temperature and a low humidity is blown toward the laundry in the drum 5. In this drying process, the bypass valve 3 is switched to the closed state, and the refrigerant discharged from the compressor 24 is circulated in the split condenser 22 and the split condenser 26, respectively. In the cooling process of step S36, the drum motor 4 and the fan motor 21 are respectively operated to rotate the drum 5, and the washing clothes in the drum 5 are blown to a lower temperature than the dry air. This cooling air is a normal temperature wind which is not heat-exchanged by the heat pump 43, and is used to cool the washing -23-200813286 laundry which is heated by the drying process of the step S35. According to the above embodiment, the following effects can be exhibited. The water supply valve 7 is formed into a cold water injection state, and the cold water injection process in which the tap water of normal temperature is not injected into the water receiving tank 3 is performed by the water pipe 1 , and after the cold water injection process is stopped, the fan device 4 1 and the compressor 24 are respectively operated to A warm air injection process for injecting warm air into the water receiving tank 3 is performed. In this warm air injection process, the high-humidity air φ absorbing the moisture in the water receiving tank 3 is returned from the water-storage tank 3 to the evaporator 23, and latent heat exchange is performed by the evaporator 23 to condense or condense the water. Therefore, even when the outside air temperature is low at about 5 °C, the evaporator is less likely to be frosted, and therefore it is possible to suppress the wind and frost from being impeded by each of the evaporator 23 and the split condenser 22. Therefore, the decrease in the operating efficiency of the heat pump 43 can be suppressed, so that the split condenser 22 and the split condenser 26 can be easily heated. The temperature of the split condenser 26 becomes much higher than the start of the warm air injection process, and the temperature of the split type condenser 26 becomes sufficiently high from the start of the warm air injection process 1 to the time of the restart of the water injection. At the time, the water supply valve 7 is switched to the warm water injection state, and the tap water is injected into the water receiving tank 3 through the water pipe 1 to start the injection process. After the warm water injection treatment is started, the tap water in the water pipe 10 is greatly heated by the heat capacity of the split type condenser 26, so that the warm water having the high heat capacity of the split type condenser 26 is absorbed. Injected into the water receiving tank 3. Therefore, the water temperature can be raised to a temperature suitable for washing clothes, so the washing ability is improved. In the present embodiment, the flow of the refrigerant of the heat pump 43 is controlled in a manner that the detection result of the evaporator temperature sensor 36 is within a predetermined range -24-200813286. Therefore, the temperature of each of the split condenser 22 and the split condenser 26 rises rapidly, and the time required to warm the tap water in the water receiving tank 3 is shortened. Further, since the temperature of the refrigerant returned from the evaporator 23 to the inside of the compressor 24 becomes high, the temperature of the lubricating oil in the compressor 24 also becomes high. Therefore, the amount of the refrigerant dissolved in the lubricating oil can be reduced, so that the lubricating property of the lubricating oil caused by the change in the dilution of the lubricating oil can be suppressed from being lowered. Therefore, it is possible to prevent the parts from being able to smoothly move inside the compressor 24, so that the reliability is improved. <Example 2> The three-way valve 45 is connected to the discharge port of the compressor 24 as shown in Fig. 8. The three-way valve 45 is driven by a valve solenoid composed of a solenoid valve. The three-way valve 45 can flow the refrigerant discharged from the compressor 24 to the water injection state of the split condenser 26 and the split condenser 22, and the refrigerant discharged from the compressor 24 does not flow to the split type condenser. 26, the dry state flowing to the split condenser 22 is switched to each other. _ Fig. 9 is a control content of the control circuit 34 when it is set to the warm water washing course. When the CPU of the control circuit 3 4 stores the tap water at the normal temperature of the water in the water tank 3, the water supply valve 7 is switched from the cold water injection state to the water injection stop state in step S7. Next, in step S8, the three-way valve 45 is switched to the water injection state, the opening degree of the electronic expansion valve 28 is initially set in step S9, and the constant speed operation of the fan motor 21 is started in step S10, in step S. 1 1 will start the fixed speed of the compressor motor 2 5 -25, 2008,13,286. Next, steps S12 to S34 are performed in the water injection state of the three-way valve 45, and the drying process in step S35 switches the three-way valve 45 from the water injection state to the dry state. Therefore, in the warm water washing process in steps S12 to S27, the refrigerant flows to the split condenser 22 and the split condenser 26, respectively, and the refrigerant does not flow to the split condenser during the drying process in step S35. However, it flows to the split type condenser 22, and therefore, in the drying process of step S35, the p generation efficiency of the warm air for drying the laundry is improved. In the second embodiment, when the temperature of the split condenser 22 rises abnormally in the drying zone of step S35, the three-way valve 45 is switched from the dry state to the water injection state, and the water supply valve 7 is switched from the water injection stop state. The warm water is injected into the water state, and heat is exchanged by the split type condenser 26 to cool the refrigerant. In each of the above-described first to second embodiments, a shell-and-tube condenser can be used as the split type condenser 26. <Example 3> Inside the main conduit 16 is a corrugated fin condenser 50 as shown in Fig. 1 . In the condenser 50, a plurality of fins are interposed between the straight portions forming one of the serpentine refrigerant tubes, and a plurality of fins are joined to the straight portions of the refrigerant tubes. Fig. 1(a) shows the piping state of the condenser 50. The refrigerant tubes 51 of the condenser 50 are arranged in four rows in the left-right direction. Here, a plurality of fins of the condenser 50 are joined with a water tube 52 which forms a meandering shape. This water pipe 52 is arranged in the left and right direction in two columns -26-200813286. The inner surface of the water pipe 52 is formed of a smooth surface as shown in Fig. 1(b). The respective rows of the water tubes 52 are interposed between the columns of the refrigerant tubes 51 as shown in Fig. 1(a), and are in indirect contact with the refrigerant tubes 51 via the fins of the condenser 52. The water pipe 52 is connected to the heating output port of the water supply valve 7 via the water pipe 1 as shown in Fig. 1, and the tap water can pass through the water pipe of the condenser 50 through the water pipe 10 in the warm water injection state of the water supply valve 7. 52 and the water injection tank 9 are injected into the water receiving tank 3. Fig. 1 is a control content of the control circuit 34 when the warm water washing stroke is set. When the CPU of the control circuit 34 stores the tap water of the normal temperature at the water level in the water receiving tank 3, the water supply valve 7 is switched from the cold water injection state to the water injection stop state in step S7. Next, the opening degree of the electronic expansion valve 28 is initially set in step S9, the constant speed operation of the fan motor 2 1 is started in step si, and the constant speed operation of the compressor motor 25 is started in step S1 1. . When it is determined that the waiting time has elapsed after the start of the constant speed operation of the compressor motor 25, the process proceeds from step S1 2 to step S17 and step S1, respectively, and the surface temperature Te of the evaporator 23 is controlled to "·5. In the setting range of °C to 〇°C", while waiting for the start of the water injection restart time, the CPU judges that the water injection restart time has elapsed in step s1, and proceeds to step S19. Here, the water supply valve 7 is switched from the water injection stop state to the warm water injection state, and the tap water is injected into the water receiving tank 3 from the water pipe 1 of the water supply valve 7 through the water pipe 52 of the condenser 50 and the water injection tank 9. In this state, the tap water in the water pipe 52 and the refrigerant in the refrigerant pipe 5 1 exchange heat with each other 'the tap water in the water pipe 5 2 is heated'. Therefore, the temperature -27-200813286 is warmer than the normal temperature. Will be injected into the water tank 3 (warm water injection). The fins of the condenser 50 are set to "〇·1 mm~〇·15 mm in order to simultaneously perform the function of heating the air and the function of transferring the heat of the refrigerant from the refrigerant pipe 51 to the tap water through the water pipe 52. "In the range. According to the third embodiment described above, the following effects can be exhibited. From the time when the warm air injection treatment starts and the water injection restart time, the temperature of the condenser 5 会 becomes much higher than the temperature of the warm air injection treatment, and the temperature of the condenser 50 becomes sufficiently high. At the time of the start, the water supply valve 7 is switched to the warm water injection state, and the tap water is injected into the water receiving tank 3 through the water pipe 52 to inject the warm water into the water tank. Immediately after the warm water injection treatment, the tap water in the water pipe 52 is greatly warmed up by the heat capacity of the absorption condenser 50, so that warm water having a high temperature that absorbs the heat capacity of the condenser 50 is injected into the water receiving tank 3. Therefore, the temperature of the water can be raised to a temperature suitable for washing clothes, and thus the washing ability is improved. In this embodiment, the condenser 50 is used to generate the structure of both warm water and warm air. Therefore, there is no need for a dedicated split type condenser 26 that warms the tap water, thereby achieving space-saving and cost reduction. In the present embodiment, the water tubes 52 of the condenser 50 are arranged in two rows in the left-right direction. Therefore, the length of the water pipe 52 in the unfolded state is shortened, so that when the water supply valve 7 is switched from the warm water injection state to the water injection stop state, the water is dropped from the water pipe 52 by the siphon effect. Therefore, water does not easily remain in the water pipe 5 2, so that ice formation and rust on the inner surface of the water pipe 52 can be prevented. The inner surface of the water pipe 52 of the present embodiment is formed into a smooth surface. Therefore, a part of the inner surface of the water -28-200813286 tube 52 does not have a stress concentration caused by icing, thereby preventing the water tube 52 from being ruptured by freezing. Further, the water does not remain on the inner surface of the water pipe 52, so that the inner surface of the water pipe 52 can be prevented from being rusted by this point. Since the columns of the water tubes 52 are interposed between the columns of the refrigerant tubes 51, the tap water in the water tubes 52 can efficiently absorb heat from the refrigerant in the refrigerant tubes 51. Moreover, this embodiment uses a corrugated fin type condenser as the condenser 50. Therefore, the thermal conductivity of the fins between the refrigerant pipe 5 1 and the water pipe 52 is increased, so that the refrigerant in the refrigerant pipe 51 and the tap water in the water pipe 52 can efficiently exchange heat with each other. <Example 4 >> At the discharge port of the compressor 24, as shown in Fig. 13, a compressor temperature sensor 55 corresponding to the compressor temperature sensor of the present invention is fixed, and is controlled. The circuit 34 detects the discharge port temperature Tr of the discharge port of the compressor 24 based on the temperature signal output from the compressor temperature sensor 55. A condenser temperature sensor 56 corresponding to the condenser temperature sensor of the present invention is fixed to the condenser 50, and the control circuit 34 is based on the temperature output from the condenser temperature sensor 56.

The CPU detects the surface -29 - 200813286 temperature Te of the evaporator 23 at step S41 of Fig. 14, and compares the detection result of the surface temperature Te with the lower reference 値 (-5 ° C). When it is judged as "Te^_5 °C", the rotation speed of the compressor motor 25 is lowered from the current speed by only the unit 値' in step S42.

When the CPU proceeds to step S44, the surface temperature Te of the evaporator 23 is detected, and the detection result of the surface temperature Te is compared with the upper reference 値 (0 ° C). When it is judged here that "Te20 °C", the number of revolutions of the compressor motor 25 is increased by only 値 from the current speed in step S45, and the opening degree of the electronic expansion valve 28 is reduced by only 値 from the current opening degree in step 846. According to the above-described fourth embodiment, the following effects can be exhibited. In the present embodiment, when the temperature difference ΔΤ of the detection result of the discharge port temperature Tr of the compressor 24 is -30-200813286 and the surface temperature Tc of the condenser 50 is "5 ° C" or more, the electronic expansion valve 28 is reduced. The opening degree is controlled, and the flow vine of the refrigerant of the heat pump 43 is controlled to control the temperature difference AT to "5 ° C" or more. Therefore, the temperature of the lubricating oil in the compressor 24 is increased, so that the amount of the refrigerant dissolved in the lubricating oil can be suppressed. Therefore, it is possible to suppress the deterioration of the lubricating performance of the lubricating oil caused by the change in the dilution of the lubricating oil, and therefore it is possible to prevent the parts from being prevented from operating smoothly in the inner bore of the compressor 24. In particular, when the outside temperature of φ is about 5 ° C, the temperature of the outlet and the inlet of the evaporator 23 will be the same as each other, so that the superheat control (supp er_ he at control) cannot be performed, but the discharge port temperature Tr The temperature difference AT of the detection result and the detection result of the surface temperature Tc is controlled to a predetermined value, for example, 5 ° C or more, so that highly reliable operation can be performed. Each of the above-described first to fourth embodiments may be carried out by dividing the warm water water injection treatment into a plurality of times. In the above-described first to fourth embodiments, the cooling of the cold water injection process in which the normal temperature tap water is injected from the Φ water supply valve 7 through the water pipe 8 into the water receiving tank 3 can be started, and the fan motor 21 and the compressor motor 25 can be started. In operation, the tap water of normal temperature is injected into the water receiving tank 3, and warm air is injected. In each of the above-described first to fourth embodiments, the water supply valve 7 may be switched to the warm water injection state when a variable water injection restart time is elapsed after the start of the constant speed operation of the compressor 24. In this case, it is preferable to detect the surface temperature of the split type condenser 26 or the like or the temperature of the warm air which is taken out into the drum 5, and when the detection result of the surface temperature or the temperature of the temperature is detected, it is recorded in the ROM in advance. When the reference is 値, the water supply valve 7 is switched to the warm water injection state. -31 - 200813286 <Example 5> In the inside of the outer casing 1, as shown in Fig. 15, a bath water pump 61 is housed. This bath water pump 61 is driven by a pump motor and takes out bath water from the bath. The discharge port of the bath water pump 61 is connected to the water injection tank 9 via the bath water pipe 62, and the opening and closing valve 63 is interposed in the bath water pipe 62. The on-off valve 63 is an open-close valve solenoid drive constituted by a solenoid valve, and is switchable between an open state and a closed state. A three-way valve 64 is provided in the water pipe 1, and the three-way valve 64 is connected to the discharge port of the bath water pump 61 via the bath water pipe 65. The three-way valve 64 is driven by a three-way valve solenoid composed of a solenoid valve, and is switchable between an open state and a locked state. These on-off valves 63 and three-way valves 64 constitute the valve mechanism 65 in the same manner as the water supply valve 7. Fig. 16 is a control content of the control circuit 34 when the warm water washing stroke using the bath water is set. The warm water washing stroke using the bath water is Φ set by the CPU of the control circuit 34 in accordance with the operation contents of the plurality of switches 33. In the warm water washing course using the bath water, the CPU starts to inject the bath water into the water receiving tank 3 in steps S4 and S19, respectively, and stops the bath water in steps S7 and S22, respectively. • Water injection action. Hereinafter, steps S4 to S22 will be described separately. When the CPU proceeds to step S4, the opening and closing valve 63 is switched to the open state in the water injection stop state of the water supply valve 7, and the three-way valve 64 is switched to the closed state. This state corresponds to the third water injection state in which the bath water drawn by the bath water pump 61 is not injected into the water receiving tank 3 by the water pipe 10 . The CPU starts to operate the pump motor in the third water injection state of the -32-200813286 valve mechanism 65, and injects the bath water from the bath through the bath pipe 62 and the water injection tank 9 into the water receiving tank 3. When the CPU determines in step S6 that the water level in the water receiving tank 3 has reached the water injection interruption level, the CPU stops the operation of the pump motor in step S7 to stop the injection of the bath water. In other words, in steps S8 to S18, the warm air is supplied into the water receiving tank 3 while the bath water is stored, and the bath water stored in the water receiving tank 3 is heated. When the CPU proceeds to step s 1 9 , the opening and closing valve 63 is switched to the closed state in the water injection stop state of the water supply valve 7, and the three-way valve 64 is switched to the open state. This state corresponds to the fourth water injection state in which the bath water drawn from the bath water pump 6 1 is injected into the water receiving tank 3 through the water pipe 10 . The CPU operates the pump motor in the fourth water injection state of the valve mechanism 65, and injects the bath water from the bath through the bath water pipe 65, the water pipe 1 and the water injection tank 9 into the water receiving tank 3 (the bath water is warmed with water). When the CPU determines in step 821 that the water level in the water receiving tank 3 has reached the setting result, the CPU stops the operation of the pump motor in step S22 to stop the injection of the bath water. In other words, in the step S1 9 to the step S2 1 , the refrigerant in the refrigerant pipe 27 of the split condenser 26 and the bath water in the water pipe 1 are exchanged with each other, and the split condenser 26 is heated. Warm water will be supplied to the water tank 3. According to the fifth embodiment described above, the following effects can be exhibited. In this embodiment, the bath water is taken out from the bath and heated. Therefore, compared with the case where the tap water is heated and warmed, the temperature of the warm water becomes high, and the washing effect of the laundry is improved. Further, when the bath water in the water receiving tank 3 is heated by the warm air, the temperature and humidity of the wind supplied from the water receiving tank 3 to the evaporator 23-33-200813286 are higher than those of the tap water, respectively. Therefore, the temperature of each of the split condenser 22 and the split condenser 26 is rapidly increased, so that the heating performance is improved. In the above-described fifth embodiment, the first water injection operation for storing the water in the water receiving tank to interrupt the water level may be performed by using the bath water pump 61, and the water level of the water level is determined by the determination result of the weight in the water receiving tank 3. The secondary water injection operation can also be performed using the water supply valve 7. In this case, when the second φ water injection is performed, the pump motor is not operated, but the water supply valve 7 is switched from the water injection stop state to the warm water injection state, and the three-way valve 64 is switched from the closed state to the open state. State, and tap water is injected into the water receiving tank 3 through the water pipe 10. In the fifth embodiment described above, when the bath water pump 61 is used for the second water injection operation, when the bath water in the bath is used up, the bath water pump 61 can be stopped, and the water supply valve 7 can be switched from the water injection stop state to The warm water is filled with water, and the tap water is injected into the water receiving tank 3 through the water pipe 10. In this case, it is preferable to detect the water level rise rate per unit time in the water receiving tank 3 when the control circuit 34 uses the bath water pump 61 to perform the second water injection operation, and when the water level rise rate is lower than previously recorded in the ROM When the standard is used, it is judged that the bath water is used up. In the above-described fifth embodiment, the fan motor 21 and the compressor motor 24 may be respectively operated during the execution of the bath water cold water injection process in which the bath water is injected into the water receiving tank 3 from the bath water pump 6 through the bath water pipe 62. While injecting the bath water into the water receiving tank 3, it injects warm air. In the first embodiment, the second embodiment, and the fifth embodiment, the water tube 1 can be indirectly contacted with the refrigerant tube of the split condenser 26 or the -34-200813286 fin via the metal heat transfer member. In the fourth embodiment, the water tube 52 may be in indirect contact with the refrigerant tube 51 or the fin of the condenser 50 via a metal heat transfer member. In each of the above-described first to fifth embodiments, the cleaning treatment of the step s 3 2 may be carried out using warm water in the same manner as in the warm water washing treatment.
