(8) 1307373 行供水動作。此時,控制裝置5 0會根據水位感測器5 3的 輸出而檢測出水槽3內的水位。接下來,驅動馬達6,旋 轉槽4即開始以低速旋轉。 在脫水運轉中,水槽3內的水被排出後,旋轉槽4便 會開始高速旋轉。此時,控制裝置5 0即會依第5圖所示 的流程圖(flow-chart),來檢查排水動作是否正常運作。也 就是說,排水動作一旦開始,即開始計算排水時間11 (步 ® 驟(step)Sl)。然後,再根據水位感測器53的輸出,一旦 檢測出水槽3內的水已被完全排出後(在步驟S2爲YES) ,再判斷排水時間Π是否在預設的正常範圍內(步驟S3) ,若是在正常範圍內的話(YES),則可續行到烘乾運轉(步 驟S4)。此外,排水時間11若不是在正常範圍時(在步驟 S3爲NO),則蜂音器55會鳴叫(步驟S5),通知洗衣水的 排水路徑受到阻礙,並停止運轉(步驟S6)。 在烘乾運轉中,係使旋轉槽4低速旋轉,並將熱風供 ® 給至旋轉槽4內來進行洗滌衣物的烘乾作業。洗滌衣物的 烘乾動作如下所述。也就是說,先驅動風扇馬達30,藉由 送風扇22的送風作用,將在水槽3內的空氣從吸入口 34 ,經過排氣導管36再流入通氣導管21內後,又通過供氣 導管35而從吐出口 33回到水槽3內。 另一方面’開始驅動構成熱泵浦25的壓縮機26。如 此一來’高溫高壓的冷媒會流入凝縮器24,而與通氣導管 21內的空氣進行熱交換。因爲如此,冷媒的溫度就會降低 而被液化’並在通過毛細管27後,流入蒸發器23。在通 -12- (9) (9)1307373 過毛細管2 7時,冷媒被減壓’而變成低溫低壓的氣液混 合狀態。再者,與凝縮器24熱交換而被加熱的空氣,會 通過供氣導管35而流入水槽3內。 流入蒸發器2 3的冷媒會與通氣導管2 1內的空氣進行 熱交換。如此一來,通過排氣導管36而流入通氣導管21 內的濕空氣就會被冷卻,空氣中的水份就會在蒸發器23 的表面凝結。凝結於蒸發器23之表面的水份,會從排洩 口 37被排到除濕排水管40內。此外,在蒸發器23,因爲 與通氣導管21內的空氣的熱交換作用,而使溫度上升的 冷媒回到壓縮機26。 就像這樣,藉由空氣在通氣導管21與旋轉槽4之間 循環,即可烘乾旋轉槽4內的洗滌衣物。 此時,控制裝置5 0即會根據第6圖所示的流程圖, 間歇性地開閉除濕用排水閥39。也就是說,烘乾運轉一旦 啓動,控制裝置50就開始計算時間t2(步驟S Π )。然後判 斷時間t2是否已達既定時間T(步驟S12),—旦到達既 定時間T(YES),就驅動齒輪馬達47而使除濕用排水閥39 開閉(步驟S 1 3 )。 在步驟S 1 4中,係判斷是否已經過烘乾運轉的設定時 間(步驟S 14),若未達設定時間的話,則時間t2重回「〇 」,又再次進行步驟S11到步驟S13的處理作業。 與通氣導管21內的空氣進行熱交換。藉由如此,經 過排氣導管3 6而流入通氣導管2】內的濕空氣,就會被冷 卻’而使空氣中的水份在蒸發器23的表面凝結。 -13- (10) (10)1307373 也就是說,在本實施例中,從烘乾運轉開始’每經過 時間T,除濕用排水閥3 9就會開閉。因此’濕空氣就會 在蒸發器2 3的表面凝結,從排洩口 3 7朝除濕用排水管4 0 內排出的水,在經過時間T的過程中,都會儲留在除濕用 排水閥3 9的前方。然後,每經過時間T,就會通過除濕 用排水閥3 9到達排水管1 3,而被排出至外部。再者,當 開閉除濕用排水閥3 9時,控制裝置5 0就會使風扇馬達3 0 停止。 本實施例係具有以下的效果。 在本實施例中,因爲除濕用排水閥3 9係呈間歇性開 閉,所以就可減少排水管1 3內的臭氣流入通氣導管2 1內 的機會。此外,因爲間歇性地開閉除濕用排水閥3 9,故可 增加通過除濕用排水閥3 9的水量,所以即使除濕用排水 閥39是在開放狀態,仍可防止臭氣流入通氣導管21內。 甚至,當除濕用排水閥3 9開閉時,送風扇2 2會停止,所 以更可確保防止臭氣流入通氣導管21內。 再者,在本實施例中,在除濕排水管4 0中,排水管 1 3的設置部份,係設有除濕用排水閥39,所以在除濕用 排水閥39的附近,即使附著了棉屑(lint ),仍可利用經 過洗衣用排水管13的水,來沖走該棉屑。 甚至,在本實施例中,其構成係爲:計算排出水槽3 內之水所須要的時間11,並判斷排水動作是否正常進行。 當判斷在排水管1 3內有棉肩等阻塞時,除了蜂音器55會 鳴叫通知外,運轉也會隨之中斷。因此,可將異常(棉屑 -14- (11) (11)1307373 阻塞)發生之情況通知使用者,而可進行排除異常狀況的 處理。此外’因爲在排水管13阻塞的狀態下,不會有排 水動作持續’或進行接下來之烘乾運轉的情形發生,所以 就可事先防止排向排水管1 3的水發生溢出(overfi〇w)的情 形。 (第2實施例) 第7及第8圖係顯示本發明的第2實施例。以下, 有關本第2實施例,因其同於第〗實施例的部份亦附予了 相同的符號’故予以省略其說明,僅針對不同之處加以說 明。如第7圖所示般’本第2實施例的構成係爲:設有在 除濕用排水管4 0中,連結除濕用排水閥3 9之正前方部位 與供水裝置5 8的通水路6 1 ’使可供水至上述除濕用排水 管40內。上述通水路61係與供水裝置5 8的供水閥62相 連接。再者,上述供水裝置58除了上述供水閥62外,又 設有2個供水閥63,64»上述供水閥63,64,係隔著供 水管66’ 67,各自與洗劑投入器65的洗劑收容部及柔軟 劑收容部(皆無圖示)連接。上述供水閥63在洗衣運轉清洗 動作時係被開放,而上述供水閥64則是在洗淨動作時被 開放。 第8圖係顯示第2實施例之烘乾運轉動作的流程圖。 該流程圖中之步驟S Π至步驟S ] 4的處理作業係同於第I 實施例(參照第6圖)。如第8圖所示般,一旦經過了烘乾 運轉的設定時間的話(在步驟s I 4中爲YES),則控制裝置 -15- (12) 1307373 50除了會開放除濕用排水閥39外(步驟si5),也會開閉 供水閥62。如此一來,既定量(數百ml)的水就會被供應 至除濕排水閥3 9中,比排水閥3 9更爲上游的位置,並在 經過除濕用排水閥3 9後,從排水管1 3流至外部。因爲這 樣的構成,則即使在除濕用排水閥3 9或其附近附著了棉 屑,仍可快速地將之洗淨沖掉。 (第3實施例) 第9圖係顯示本發明之第3實施例。以下,有關本第 3實施例,因其同於第2實施例的部份,係被附予了相同 的符號故省略其說明,僅針對不同之處加以說明。在本第 3實施例中 > 在烘乾運轉過程中,係間歇性地將水供給至 除濕用排水管40,以利其沖洗棉屑。也就是說,在第9圖 的流程圖中,一旦烘乾運轉啓動,控制裝置5 0即開始計 算時間t3(步驟S21),當時間t3到達既定時間T1的話(步 驟S22),則開放除濕用排水閥39(步驟S23)。接下來,判 斷時間t3是否已到達既定時間T2(步驟S24),在時間t3 還沒到達既定時間T2時’則在關閉除濕用排水閥3 9後( 步驟S25),又重回步驟S21。 另一方面,當時間t3到達既定時間T2時(在步驟S24 爲Y E S),則使供水閥6 2開閉(步驟S 2 6)。如此一來,就 會供水至除濕用排水管4 0,該水就會通過除濕用排水閥 3 9。之後’再判斷烘乾運轉的設定時間是否已超過(步驟 S 2 7),當烘乾運轉持續時’則關閉除濕用排水閥39(步驟 -16 -

[Prior Art] A heat pump system is a system that uses a heating device that uses a refrigeration cycle to heat up on a low temperature side and heats it on a high temperature side. Compared with the conventional heating system that uses fossil fuels such as petroleum to obtain thermal energy, it is more efficient and has less environmental load. Here, for example, a washing and drying machine that washes laundry in a washing tank by heat pumping as described in Japanese Laid-Open Patent Publication No. 2004-13575. The hot Lipu system is a heating/cooling system that uses a refrigeration cycle, which is a system that uses a refrigerant that is a medium for transporting heat on the low temperature side to suck heat up and transport heat to the high temperature side. ). Heat pumping has the advantage of being more efficient and less burdensome on the environment than conventional heating systems that use fossil fuels such as petroleum to obtain thermal energy. Here, for example, a washing and drying machine that uses heat pumping to dry laundry in a washing tank is disclosed in Japanese Patent Publication No. 2004-13575. The drying device of the heat-pumped laundry dryer includes an air passage connected to the discharge port and the suction port of the washing tank, and a blower, a condenser, and an evaporator disposed in the air passage. And the compressor and the expansion (2) 1307373 valve, which together with the condenser and the evaporator, constitute a heat pump (refrigeration cycle). In the above-described drying device, by the air blowing action of the blower, the humid air in the washing tank is discharged into the air passage 6 and the air discharged into the air passage is passed through the evaporator on the low temperature side of the refrigeration cycle. That is, it is cooled and dehumidified, and then heated while passing through the condenser, and returned from the suction port to the washing tank. In the air passage, between the evaporator and the condenser, the dehumidification drain pipe is connected, and the water condensed on the surface of the evaporator by the air is cooled in the evaporator, and can be discharged from the dehumidification drain pipe. Call out. [Patent Document 1] JP-A-2004-135715 SUMMARY OF INVENTION [Problems to be Solved by the Invention] Condensers or evaporators are arranged in a plurality of aluminum sheets (a] uminiump 1 ate) in order to improve heat exchange efficiency. Very small spacing. Therefore, there is considerable air resistance in the air passage in which the condenser or evaporator is disposed. In order to counteract this air resistance and ensure a sufficient amount of circulating air in the air passage, it is necessary to arrange a blower having a large static pressure between the outlet of the condenser and the discharge port. However, if a large static pressure blower is placed between the outlet of the condenser and the discharge port, the air in the air passage is pulled by the dehumidification drain pipe and becomes a negative pressure. The air in the drainage path located at the downstream portion of the dehumidification drain pipe does not easily flow into the air passage. If the bacteria are attached to the drainage path, it is prone to rancidity. Once the air in the drainage path passes through the air passage and flows into the washing tank, the rancid smell of the -6-(3) 1307373 bacteria is attached to the clothes. The problem. The present invention has been made in view of the above problems, and an object thereof is to provide a washing and drying machine capable of preventing air in a dehumidifying drainage path from flowing into a washing tank in a configuration in which laundry is washed by heat pumping.

The tube 4 2 moves up and down against the recovery spring 4 4 . In this way, the drain valve for washing machine 1 and the drain valve for dehumidification can be opened and closed. Figure 4 is a block diagram showing the electrical composition of the washer-dryer 1 (b 1 0 ck d i a gr am). The control device 50 as a control means controls the entire operation of the washing and drying machine 1, and is constituted by a micro-computer. The control device 50 is connected to a lid switch 51, an operation unit 52, a water level detector 53, a display unit 54', a buzzer 55, and the like. Further, the control device 50 is connected to the motor 6 via the inverter 56. Even in the above-described control device 50, the fan motor 30, the compressor motor 26a, the water supply device 58, and the gear motor 46, 47 are in contact with each other via the drive circuit 57'. Next, the action of this embodiment will be described. First, the outline of the washing and drying machine 1 will be described. When the operation unit 52 is operated, the course of operation is set, and the instruction to start the operation is given, the washer-dryer 1 starts the laundry operation, the drying operation, or the laundry operation and baking according to the set operation washing process. Dry running laundry drying operation. For example, when the washing and drying operation is started, the laundry operation, the dehydration operation, and the drying operation are performed in the order. In the washing operation, the water supply device 5 4 can drive the water supply to the water tank 3 by -11 - (8) 1307373. At this time, the control device 50 detects the water level in the water tank 3 based on the output of the water level sensor 53. Next, the motor 6 is driven, and the rotary groove 4 starts to rotate at a low speed. In the dehydration operation, after the water in the water tank 3 is discharged, the rotary tank 4 starts to rotate at a high speed. At this time, the control device 50 checks whether the drainage operation is normal or not in accordance with the flow chart (flow-chart) shown in Fig. 5. That is to say, once the drainage action has started, the drainage time 11 is calculated (step S1). Then, based on the output of the water level sensor 53, once it is detected that the water in the water tank 3 has been completely discharged (YES in step S2), it is determined whether the drainage time Π is within a preset normal range (step S3). If it is within the normal range (YES), it can be continued to the drying operation (step S4). Further, if the drain time 11 is not in the normal range (NO in step S3), the buzzer 55 will beep (step S5), and the drain path of the washing water is notified to be blocked, and the operation is stopped (step S6). In the drying operation, the rotary tub 4 is rotated at a low speed, and the hot air supply is supplied to the rotary tub 4 to perform the drying operation of the laundry. The drying action of the laundry is as follows. That is, the fan motor 30 is driven first, and the air in the water tank 3 is again flowed into the ventilation duct 21 from the suction port 34 through the exhaust duct 36 by the air blowing action of the blower fan 22, and then passes through the air supply duct 35. The discharge port 33 is returned to the water tank 3. On the other hand, the compressor 26 constituting the heat pump 25 is started to be driven. As a result, the high-temperature high-pressure refrigerant flows into the condenser 24 to exchange heat with the air in the ventilation duct 21. Because of this, the temperature of the refrigerant is lowered to be liquefied and flows into the evaporator 23 after passing through the capillary 27. When the -12-(9) (9) 1307373 passes through the capillary 2 7 , the refrigerant is depressurized and becomes a low-temperature low-pressure gas-liquid mixture state. Further, the air heated by the heat exchange with the condenser 24 flows into the water tank 3 through the air supply duct 35. The refrigerant flowing into the evaporator 23 exchanges heat with the air in the ventilation duct 21. As a result, the humid air that has flowed into the ventilation duct 21 through the exhaust duct 36 is cooled, and the moisture in the air is condensed on the surface of the evaporator 23. The moisture condensed on the surface of the evaporator 23 is discharged from the drain port 37 into the dehumidification drain pipe 40. Further, in the evaporator 23, the refrigerant having a temperature rise returns to the compressor 26 because of heat exchange with the air in the air duct 21. As such, the laundry in the rotary tub 4 can be dried by circulating air between the venting duct 21 and the rotary tub 4. At this time, the control device 50 intermittently opens and closes the dehumidification drain valve 39 in accordance with the flowchart shown in FIG. That is, once the drying operation is started, the control device 50 starts calculating the time t2 (step S Π ). Then, it is judged whether or not the time t2 has reached the predetermined time T (step S12), and when the predetermined time T (YES) is reached, the gear motor 47 is driven to open and close the dehumidification drain valve 39 (step S13). In step S14, it is determined whether the set time of the drying operation has been passed (step S14), and if the set time has not been reached, the time t2 is returned to "〇", and the processing of steps S11 to S13 is performed again. operation. Heat exchange is performed with the air in the ventilation duct 21. As a result, the humid air that has flowed into the ventilation duct 2 through the exhaust duct 36 is cooled, and the moisture in the air is condensed on the surface of the evaporator 23. -13- (10) (10) 1307373 In other words, in the present embodiment, the dehumidification drain valve 39 is opened and closed every elapsed time T from the start of the drying operation. Therefore, 'wet air will condense on the surface of the evaporator 23, and the water discharged from the drain port 37 toward the dehumidification drain pipe 40 will be stored in the dehumidification drain valve during the passage of time T3. The front. Then, every time T elapses, it reaches the drain pipe 13 through the dehumidification drain valve 39, and is discharged to the outside. Further, when the dehumidification drain valve 39 is opened and closed, the control unit 50 stops the fan motor 30. This embodiment has the following effects. In the present embodiment, since the dehumidification drain valve 39 is intermittently opened and closed, the chance of the odor in the drain pipe 13 entering the ventilation duct 2 1 can be reduced. Further, since the dehydration drain valve 3 is intermittently opened and closed, the amount of water passing through the dehumidification drain valve 39 can be increased. Therefore, even if the dehumidification drain valve 39 is in an open state, it is possible to prevent the odor from entering the ventilation duct 21. Even when the dehumidification drain valve 39 is opened and closed, the blower fan 2 2 is stopped, so that it is possible to ensure that the odorless airflow is prevented from entering the ventilation duct 21. Further, in the present embodiment, in the dehumidification drain pipe 40, the dehumidification drain valve 39 is provided in the portion where the drain pipe 13 is provided, so that even in the vicinity of the dehumidification drain valve 39, even if cotton dust adheres thereto (lint), the water passing through the laundry drain pipe 13 can still be used to wash away the cotton dust. Even in the present embodiment, the configuration is such that the time required to discharge the water in the water tank 3 is calculated, and it is judged whether or not the drainage operation is normally performed. When it is judged that there is a blockage such as a cotton shoulder in the drain pipe 13, the operation will be interrupted in addition to the notification by the buzzer 55. Therefore, the user can be notified of the occurrence of an abnormality (cotton -14-(11) (11)1307373 obstruction), and the abnormal condition can be handled. In addition, 'because the drainage pipe 13 is blocked, there is no drainage operation continued' or the subsequent drying operation occurs, so that the water discharged to the drain pipe 13 can be prevented from overflowing in advance (overfi〇w ) situation.
