Description

洗衣烘乾機 Laundry dryer

本發明係關於洗衣烘乾機。 The present invention relates to a laundry dryer.

在有過敏性皮膚炎或氣喘患者的家庭中，為了排除過敏原，不只是頻繁地打掃房間，還要注意保持直接接觸肌膚之衣物或毛毯、被子等的清潔。毛毯或被子，係直接與人類長時間接觸，皮垢或頭皮屑等成為塵蟎之食物的物質較豐富，且由於較厚故有著成為住處的場所，因此會是適合塵蟎棲息的環境。毛毯或被子一般係以曬太陽的加溫、低濕度化和藉由吸塵器的吸引來去除塵蟎類。但是，塵蟎係在內部比在表面還多，因曬太陽時內部的溫度無法充分上昇，且由於較厚故吸塵器難以吸到內部等，不容易去除塵蟎類。因此，為了保持清潔，亦大多希望毛毯或被子等之大洗衣物盡量在自宅進行洗衣、烘乾。最近的洗衣烘乾機，隨著大容量化有所進展，逐漸比較容易在家庭弄出可洗衣、烘乾毛毯或被子的環境。 In families with allergic dermatitis or asthma, in order to eliminate allergens, not only frequently clean the room, but also keep the clothing or blankets, quilts, etc. that are in direct contact with the skin clean. Blankets or quilts are directly in contact with humans for a long time. The materials that become dust mites such as smudges or dandruff are abundant, and because they are thick, they have a place to live, so they are suitable for dust mites. Blankets or quilts are generally heated by the sun, low humidity and attracted by the vacuum cleaner to remove dust mites. However, there are many dust mites in the interior than in the surface, and the internal temperature cannot be sufficiently raised during the sun exposure, and since the vacuum cleaner is difficult to suck into the interior, it is not easy to remove dust mites. Therefore, in order to keep it clean, most of the large laundry items such as blankets or quilts are expected to be washed and dried in the house as much as possible. Recently, the washing and drying machine has become more and more easy to produce laundry, drying blankets or quilts in the home environment as the capacity has increased.

[非專利文獻1]吉川翠，家屋內棲息性塵蟎類的生態及關於防除的研究(1)~(8)，家屋害蟲，Vol.13~Vol.18，(1991年~1995年) [Non-Patent Document 1] Ji Chuancui, Ecology of Habitat Dust Mites in Houses and Research on Control (1)~(8), House House Pests, Vol.13~Vol.18, (1991-1995)

針對在家屋內的寢具或榻榻米、地毯、木地板等棲息之塵蟎的種類與其構成比進行調査的結果，塵蟎科佔70%以上，其他的細蟎科(Tarsonemidae)、粉蟎科(Acaridae)、肉食蟎科(Cheyletidae)、單甲蟎科(Haplochthoniidae)等約為數%左右。作為塵蟎對人體造成的被害，已知有肉食蟎科的塵蟎咬噬所造成的皮膚發炎，或塵蟎的屍體或糞便所造成的氣喘或過敏性鼻炎症狀。特別是，佔大部分之塵蟎科的塵蟎糞便有著特別高的過敏活性，不只是塵蟎本身，連糞便的去除也很重要。但是，糞便不僅是在毛毯或被子的表面，亦多數存在於內部，故雖然藉由拍打表面以吸塵器吸引便可去除，但要充分去除並不容易。 For the results of investigations on the types of bedding, tatami mats, carpets, and wooden floors in the house, the dust mites accounted for more than 70%, and other Tarsonemidae and whiteflies ( Acaridae), Cheyletidae, Haplochthoniidae, etc. are about a few percent. As a nuisance caused by dust mites, it is known that the skin is inflamed by the dust mites of the carnivorous mites, or the symptoms of asthma or allergic rhinitis caused by dusty corpses or feces. In particular, the dust mite feces of most of the Dust mites have a particularly high allergic activity, not only the dust mites themselves, but also the removal of faeces. However, feces are not only on the surface of the felt or quilt, but also mostly inside, so although it can be removed by tapping the surface with a vacuum cleaner, it is not easy to remove it sufficiently.

塵蟎係藉由提昇溫度便可使其死絕，由實驗結果公開指出，以50℃保持20分鐘的話，屋內最多之塵蟎科的塵蟎會100%死絕。且，附著在較薄的床單等的塵蟎係藉由 洗衣的水流或機械作用而可去除99%以上，但毛毯或被子的情況，塵蟎係在內部故洗衣的水流或機械作用難以到達，難以藉由洗衣來去除。但是，作為過敏原之塵蟎的糞便係水溶性，故藉由對毛毯或被子的內部通水便可去除。因此，首先保持高溫度使塵蟎死絕之後，以洗衣排除過敏原(塵蟎的屍體或糞便)後進行烘乾可有效排除塵蟎與過敏原。 The dust mites can be killed by raising the temperature. It is publicly pointed out from the experimental results that if the temperature is kept at 50 ° C for 20 minutes, the dust mites of the dust mites in the house will be 100% dead. Moreover, the dust mites attached to the thin sheets and the like are The water flow or mechanical action of the laundry can be removed by more than 99%. However, in the case of a blanket or quilt, the dust mites are internal, so the water flow or mechanical action of the laundry is difficult to reach, and it is difficult to remove by washing. However, the feces of the dust mites, which are allergens, are water-soluble, so that they can be removed by passing water through the inside of the felt or quilt. Therefore, after maintaining the high temperature to make the dust mites die, drying the allergens (dust corpses or feces) after washing can effectively eliminate dust mites and allergens.

作為洗衣機之被子的洗衣方法，有著抑制內部棉團的移動，防止變形的滾筒式洗衣機。且，有著促進滾筒與被子之間接觸面的烘乾，使烘乾時間短縮或減低烘乾不均的洗衣烘乾機。此外，有著對洗衣槽供給溫水，使附著於洗衣物的塵蟎死絕之具有殺塵蟎功能的洗衣機。 As a washing method of a quilt of a washing machine, there is a drum type washing machine which suppresses movement of an inner cotton lump and prevents deformation. Moreover, there is a washing and drying machine which promotes the drying of the contact surface between the drum and the quilt, shortens the drying time or reduces the uneven drying. In addition, there is a washing machine that supplies warm water to the washing tank and causes the dust mites attached to the laundry to die.

於圖7表示在洗衣烘乾機設定洗衣烘乾行程的情況之運轉控制流程的一例。切入電源開關時，控制裝置係進行狀態確認來實行洗衣烘乾機的初始設定(S101)。在使用者選擇洗衣烘乾行程後按下開始開關(S102)時，控制裝置係實行洗衣步驟(依序進行洗滌、沖洗、脫水)(S103)。洗衣步驟結束後實行烘乾步驟(高速脫水、溫風烘乾)(S104)，在檢測出衣物乾燥，或是經過事先決定的時間之後結束烘乾步驟，並結束運轉。如上述般依序施行洗衣、烘乾。 An example of the operation control flow in the case where the washing and drying process is set in the washing and drying machine is shown in FIG. When the power switch is cut, the control device performs status confirmation to perform initial setting of the washer dryer (S101). When the user selects the laundry drying stroke and then presses the start switch (S102), the control device performs a washing step (sequential washing, rinsing, dehydration) (S103). After the washing step is completed, a drying step (high-speed dehydration, warm air drying) is performed (S104), and the drying step is terminated after the predetermined time is detected, and the drying operation is terminated. Washing and drying are carried out in sequence as described above.

為了使用上述的洗衣烘乾機，來進行能有效去除上述之塵蟎或過敏原(塵蟎糞便)的運轉，首先，能思及在將乾燥的毛毯或被子放入洗衣烘乾機之後，設定烘乾行程來 進行將溫風吹附於毛毯或被子來使溫度上昇的運轉，使塵蟎死絕。此時，一般的洗衣烘乾機中，係自動檢測出烘乾結束，由於是放入乾燥的毛毯或被子，故會在短時間便結束運轉，很有可能無法將毛毯或被子加溫至充分的溫度。因此，以手動來設定烘乾運轉時間較佳，但是使用者並不知道毛毯或被子的溫度係如何來上昇。若時間過短則溫度沒有充分上昇，若時間過長，溫度會過高而有著使毛毯或被子被熱傷害之虞。如上述般，有著難以適當設定烘乾運轉時間的課題。且，烘乾運轉結束後，接著就是設定洗衣烘乾行程，進行洗衣運轉(過敏原的去除)、烘乾運轉。因此，有必要先進行烘乾行程的設定，在烘乾運轉結束後，進行洗衣烘乾行程的設定，有著手續麻煩的課題。 In order to use the above-described washing and drying machine to perform the operation of effectively removing the above-mentioned dust mites or allergens (dust mites), first, it is possible to set after putting a dried felt or quilt into the washing and drying machine. Drying trip The operation of blowing warm air to the blanket or quilt to raise the temperature is carried out to make the dust mites die. At this time, in the general washing and drying machine, the drying is automatically detected. Since the dry blanket or quilt is placed, the operation will be completed in a short time, and it is very likely that the blanket or the quilt cannot be warmed up sufficiently. temperature. Therefore, it is better to set the drying operation time manually, but the user does not know how the temperature of the felt or the quilt rises. If the time is too short, the temperature does not rise sufficiently. If the time is too long, the temperature will be too high and the blanket or quilt will be damaged by heat. As described above, there is a problem that it is difficult to appropriately set the drying operation time. Further, after the drying operation is completed, the laundry drying process is set, and the washing operation (removal of allergens) and the drying operation are performed. Therefore, it is necessary to set the drying stroke first, and after the drying operation is completed, the setting of the washing and drying stroke is performed, which has a problem of troublesome procedures.

上述專利文獻1中，係具備使用吸水發熱材(合成沸石)的供溫水裝置，在短時間產生50~60℃的溫水來供給至洗衣槽。但是，使15L的水從15℃加熱至50℃必須要10kg的合成沸石。專利文獻1所請發明中，為了進行毛毯或被子類的塵蟎去除，而將毛毯或被子全體泡在溫水時，需要50L左右的水量。因此，必須要有30~40kg的合成沸石，若將供溫水裝置內藏於洗衣機的話，框體尺寸會大型化，在家庭之設置性的面向上會成為課題。 In the above-mentioned Patent Document 1, a warm water supply device using a water-absorbing heat-generating material (synthetic zeolite) is provided, and warm water of 50 to 60 ° C is generated in a short time to be supplied to the washing tank. However, 10 kg of synthetic zeolite is required to heat 15 L of water from 15 ° C to 50 ° C. In the invention of the patent document 1, in order to remove the dust mites of the felt or the quilt, the entire amount of the felt or the quilt is soaked in warm water, and the amount of water of about 50 L is required. Therefore, it is necessary to have 30 to 40 kg of synthetic zeolite. If the water heater is installed in a washing machine, the size of the casing will be increased, which will become a problem in the setting of the home.

且，於上述專利文獻2，記載著關於可去除洗衣物之過敏原的洗衣機械及控制方法的發明。但是，由於另外需要蒸氣產生器，故框體尺寸有著大型化之虞。 Further, in the above Patent Document 2, an invention relating to a washing machine and a control method capable of removing an allergen of a laundry is described. However, since a steam generator is additionally required, the size of the casing is large.

在此，本發明的目的係提供：有效地進行毛毯或被子 類等之塵蟎或糞便的去除，且框體尺寸不會大型化的洗衣烘乾機。 Here, the object of the present invention is to provide an effective blanket or quilt A washing and drying machine that removes dust mites or feces from the class and does not enlarge the size of the frame.

The washing water flows through the wall surface of the air supply passage to wash off the dust adhering to the wall surface.

送風通路19的上部，係連接於過濾器風道35，該過濾器風道35係於前後方向設置在框體1內的上部右側。在送風通路19上部之與過濾器風道35的連接部處具有風路切換閥。於過濾器風道35的前面具有開口部，於該開口部***有抽出式的烘乾過濾器22。 The upper portion of the air supply passage 19 is connected to the filter duct 35, and the filter duct 35 is provided on the upper right side of the casing 1 in the front-rear direction. An air passage switching valve is provided at a connection portion of the upper portion of the air supply passage 19 to the filter air passage 35. An opening is formed in the front surface of the filter duct 35, and a drawing type drying filter 22 is inserted into the opening.

從送風通路19進入過濾器風道35的空氣，係流入烘 乾過濾器22的網狀過濾器22a而除去棉屑。烘乾過濾器22的清掃，係將烘乾過濾器22抽出而取出網狀過濾器22a來進行。且，於過濾器風道35之烘乾過濾器22***部的內面設有開口部23，該開口部23係連接有吸氣閥23a，吸氣閥23a的另一端係與送風單元24的吸氣口連接。 The air entering the filter duct 35 from the air supply passage 19 flows into the drying The mesh filter 22a of the filter 22 is dried to remove cotton chips. The cleaning of the drying filter 22 is performed by extracting the drying filter 22 and taking out the mesh filter 22a. Further, an opening portion 23 is formed in an inner surface of the insertion portion of the drying filter 22 of the filter duct 35. The opening portion 23 is connected to an intake valve 23a, and the other end of the intake valve 23a is connected to the air blowing unit 24. The suction port is connected.

送風單元24，係由驅動用馬達25、風扇葉輪26、風扇殼24a所構成。於風扇殼24a內藏有加熱器27，加熱從風扇葉輪26所送出的空氣。 The blower unit 24 is composed of a drive motor 25, a fan impeller 26, and a fan case 24a. A heater 27 is housed in the fan case 24a to heat the air sent from the fan impeller 26.

加熱器27，係可切換輸入，本實施例的加熱器中具有強模式與弱模式。送風單元24係連接於溫風風道28。溫風風道28，係透過橡膠製的蛇腹管28a、蛇腹管接頭29，而連接於設在外槽蓋8a的前部吹出口30。 The heater 27 is a switchable input, and the heater of this embodiment has a strong mode and a weak mode. The air blowing unit 24 is connected to the warm air duct 28 . The warm air duct 28 is connected to the front air outlet 30 provided in the outer tank cover 8a via a rubber bellows pipe 28a and a bellows pipe joint 29.

本實施例中，送風單元24係設在框體1內的上部右側，故前部吹出口30係設在外槽蓋8a之右斜上的位置，盡量縮短到達前部吹出口30為止的距離，來使壓力損失或熱喪失成為最低限度。 In the present embodiment, the air blowing unit 24 is disposed on the upper right side of the casing 1, so that the front air outlet 30 is disposed at the right oblique position of the outer tank cover 8a, and the distance to the front air outlet 30 is minimized. To minimize pressure loss or heat loss.

於排水口12的出口設有溫度感測器34，於送風單元24的入口設有溫度感測器32，於加熱器27出口設有溫度感測器31。 A temperature sensor 34 is provided at the outlet of the drain port 12, a temperature sensor 32 is provided at the inlet of the blower unit 24, and a temperature sensor 31 is provided at the outlet of the heater 27.

烘乾運轉時之風的流動係如下。使送風單元24運轉，並對加熱器27通電時，從前部吹出口30對洗衣兼脫水槽7內吹入溫風，吹拂潮濕的衣物來加溫，使水分從衣物蒸發。烘乾運轉中，係使洗衣兼脫水槽7正反旋轉，故 反覆進行以昇降器7e抬起衣物並以重力落下的動作，使溫風均勻遍及衣物。成為高溫多濕的空氣，係從設在洗衣兼脫水槽7的貫通孔流向外槽8，而從吸氣口20被吸入送風通路19，於送風通路19由下往上流動。於送風通路19的壁面，使來自水冷除濕機構的冷卻水流動落下，高溫多濕的空氣係與冷卻水接觸而進行冷卻除濕，成為乾燥的低溫空氣並進入烘乾過濾器22。通過設在烘乾過濾器22的網狀過濾器22a而將棉屑去除後，被吸入送風單元24。然後，在以送風單元24加壓之後以加熱器27再次加熱，並吹入洗衣兼脫水槽7內來循環。在網狀過濾器22a與送風單元24之間，設有溫度感測器32，其測量循環空氣的溫度。 The flow of the wind during the drying operation is as follows. When the blower unit 24 is operated and the heater 27 is energized, warm air is blown into the washing and dewatering tank 7 from the front blower port 30, and moist laundry is blown to warm the water to evaporate from the laundry. During the drying operation, the washing and dewatering tank 7 is rotated forward and backward, so The action of lifting the clothes by the lifter 7e and dropping it by gravity is repeated to make the warm air evenly spread over the clothes. The high-temperature and high-humidity air flows into the outer tank 8 from the through hole provided in the washing and dewatering tank 7, and is sucked into the air passage 19 from the air inlet 20, and flows downward from the air passage 19. The cooling water from the water-cooling/dehumidifying mechanism flows down on the wall surface of the air supply passage 19, and the high-temperature and humid air comes into contact with the cooling water to be cooled and dehumidified, and becomes dry low-temperature air and enters the drying filter 22. The cotton dust is removed by the mesh filter 22a provided in the drying filter 22, and then sucked into the air blowing unit 24. Then, after being pressurized by the blower unit 24, the heater 27 is again heated and blown into the washing and dewatering tank 7 to circulate. Between the mesh filter 22a and the blower unit 24, a temperature sensor 32 is provided which measures the temperature of the circulating air.

圖3為本實施例之滾筒式洗衣烘乾機之控制裝置33的方塊圖。50係微電腦，其與連接於各操作按鈕4、5的操作按鈕輸入電路51或水位感測器、溫度感測器連接，接收使用者的按鈕操作或洗衣步驟、烘乾步驟之各種資訊訊號。來自微電腦50的輸出，係連接於驅動電路54，且連接於供水電磁閥18、排水閥14、馬達10、送風單元24、加熱器27等，控制該等的開閉或旋轉、通電。且，連接於讓使用者得知洗衣烘乾機之動作狀態用的七段顯示器發光二極體或是液晶的顯示器6或蜂鳴器57。 Figure 3 is a block diagram of the control device 33 of the drum type laundry dryer of the present embodiment. The 50-series microcomputer is connected to the operation button input circuit 51 or the water level sensor and the temperature sensor connected to the operation buttons 4 and 5, and receives various information signals of the button operation or the washing step and the drying step of the user. The output from the microcomputer 50 is connected to the drive circuit 54, and is connected to the water supply solenoid valve 18, the drain valve 14, the motor 10, the blower unit 24, the heater 27, and the like, and controls such opening and closing, rotation, and energization. Further, it is connected to a seven-segment display light-emitting diode or a liquid crystal display 6 or buzzer 57 for letting the user know the operating state of the washing and drying machine.

前述微電腦50，在按下電源開關3來切入電源時，實行圖4所示般的洗衣及烘乾控制處理。圖4為毛毯或被子之塵蟎或糞便去除用的「過敏原去除行程」(一例)的 動作流程。 The microcomputer 50 performs the washing and drying control process as shown in FIG. 4 when the power switch 3 is pressed to cut in the power. Figure 4 shows the "allergen removal route" (an example) for removing blankets or quilts from blankets or quilts. Action flow.

使用者對洗衣兼脫水槽7放入洗衣物，在此為毛毯或被子，並關上門9，按下電源開關3時，微電腦50係進行洗衣烘乾機的狀態確認及初始設定(S110)。點亮操作面板2的顯示器6，依照來自操作按鈕5的指示輸入來設定過敏原去除行程(S111)。 When the user puts laundry into the washing and dewatering tank 7, where it is a felt or a quilt, and closes the door 9, when the power switch 3 is pressed, the microcomputer 50 performs the state confirmation and initial setting of the washing and drying machine (S110). The display 6 of the operation panel 2 is turned on, and the allergen removal process is set in accordance with an instruction input from the operation button 5 (S111).

當操作面板2的開始按鈕4被按下時，實施熱風處理步驟(S112)。熱風處理步驟，係使送風單元24運轉，使馬達25與風扇葉輪26旋轉(S112A)。接著，於加熱器27通電(S112B)，將洗衣兼脫水槽7以事先決定的轉數來旋轉(S112C)，並對洗衣物吹附溫風，使洗衣物的溫度上昇。加熱器27之輸出強弱可變的加熱器，係使加熱器成為弱模式讓洗衣物的溫度不會上升至過高。 When the start button 4 of the operation panel 2 is pressed, the hot air processing step (S112) is performed. In the hot air treatment step, the blower unit 24 is operated to rotate the motor 25 and the fan impeller 26 (S112A). Next, the heater 27 is energized (S112B), and the washing and dewatering tank 7 is rotated at a predetermined number of revolutions (S112C), and the warm air is blown to the laundry to raise the temperature of the laundry. The output of the heater 27 is a variable-varist heater that causes the heater to be in a weak mode so that the temperature of the laundry does not rise too high.

又，亦可為了縮短熱風處理步驟的時間，而使加熱器27成為強模式。但是，熱風處理步驟係使乾燥之洗衣物的溫度上昇，故有著洗衣物表面溫度過高而產生溫度所造成的傷害之虞。在此，於加熱器27與前部吹出口30之間設置溫度感測器31來檢測溫風的溫度，當溫風溫度超過例如70℃時使加熱器27成為弱模式(或OFF模式)亦可。溫風，係如上述烘乾運轉時的風之流動來循環，但熱風處理步驟S112中，由於係加溫乾燥的洗衣物，故不需要冷卻水的除濕。 Further, the heater 27 may be in a strong mode in order to shorten the time of the hot air treatment step. However, the hot air treatment step causes the temperature of the dried laundry to rise, so that the surface temperature of the laundry is too high and the temperature is caused by the damage caused by the temperature. Here, a temperature sensor 31 is provided between the heater 27 and the front air outlet 30 to detect the temperature of the warm air, and when the warm air temperature exceeds, for example, 70 ° C, the heater 27 is made into a weak mode (or OFF mode). can. The warm air is circulated by the flow of the wind during the above-described drying operation, but in the hot air treatment step S112, since the laundry is heated and dried, the dehumidification of the cooling water is not required.

洗衣兼脫水槽7的旋轉方向可為單方向亦可為反覆正反旋轉。且，亦可將洗衣兼脫水槽7的轉數，在例如每分 鐘40轉左右到100轉左右變化。毛毯或被子由於體積較大，故折疊來投入洗衣兼脫水槽7，而佔據洗衣兼脫水槽7之容積的大部分，導致以昇降器7c抬起落下的動作較少。在此，使洗衣兼脫水槽7的轉數例如比烘乾步驟時的轉數還高，來以離心力推向洗衣兼脫水槽7的壁面時，溫風不易到達之洗衣物的中心部會出現空間，溫風會從該空間進入，故可有效率地提高洗衣物全體的溫度。此外，使送風單元24成為高壓型(使風扇葉輪高速旋轉)，減小前部吹出口30的面積，藉此使來自前部吹出口30的高速溫風吹出至洗衣兼脫水槽7內。藉此，溫風較容易進入洗衣物之折疊的間隙，可加速洗衣物內部的溫度上昇。 The rotation direction of the washing and dewatering tank 7 may be a single direction or a reverse front and back rotation. Moreover, the number of revolutions of the washing and dewatering tank 7 can also be, for example, per minute The clock changes from around 40 to about 100 turns. The blanket or quilt is folded into the laundry and dewatering tank 7 due to its large size, and occupies most of the volume of the washing and dewatering tank 7, resulting in less movement of the lifter 7c to lift and fall. Here, when the number of revolutions of the washing and dewatering tank 7 is made higher than the number of revolutions in the drying step, for example, when the centrifugal force is pushed to the wall surface of the washing and dewatering tank 7, the center portion of the laundry which is difficult to reach by the warm air may appear. Space, warm wind will enter from this space, so it can effectively increase the temperature of the whole laundry. Further, the air blowing unit 24 is made into a high pressure type (the fan impeller is rotated at a high speed), and the area of the front air outlet 30 is reduced, whereby the high speed warm air from the front air outlet 30 is blown into the washing and dewatering tank 7. Thereby, the warm wind can easily enter the gap of the folding of the laundry, and the temperature rise inside the laundry can be accelerated.

熱風處理步驟的時間，係進行至毛毯或被子內潛藏的塵蟎死絕為止。具體來說，係如前述般，棲息於家屋內的塵蟎係在50℃放置20分鐘便會100%死絕，故從洗衣物之最低部分的溫度到達50℃時起算最少也需要20分鐘。洗衣物的溫度，比起溫風直接吹拂的表面，內部方面會延遲上昇，但難以檢測內部的溫度。在此，事先調查對洗衣物(可考慮到之最厚者)吹附溫風的時間與內部(溫度上昇最慢的部分)溫度的關係，以實驗來求出對加熱器27通電之後內部溫度到達50℃的時間T。然後，於該時間加上20分，考量到餘裕的話以加上30分以上來設為熱風處理步驟的時間即可。時間T係受到加熱器27的容量或送風單元24的風量所影響，故當然可配合洗衣烘乾機的規格來設定。 The time of the hot air treatment step is carried out until the dust mites hidden in the blanket or quilt are dead. Specifically, as described above, the dust mites that are inhabited in the house will be 100% dead after being left at 50 ° C for 20 minutes, so it takes at least 20 minutes from the time when the temperature of the lowest part of the laundry reaches 50 ° C. The temperature of the laundry is delayed compared to the surface directly blown by the warm air, but it is difficult to detect the internal temperature. Here, the relationship between the time when the warm air is blown to the laundry (the thickest one can be considered) and the temperature of the inside (the portion where the temperature rises the slowest) is investigated in advance, and the internal temperature after the heater 27 is energized is experimentally determined. Time T reaching 50 °C. Then, 20 points are added to the time. When the amount is exceeded, 30 minutes or more is added to set the time for the hot air treatment step. The time T is affected by the capacity of the heater 27 or the air volume of the air blowing unit 24, so it can of course be set in accordance with the specifications of the washing and drying machine.

在加熱器27通電之後的經過時間成為例如T+30分以上時(S112D)，停止對加熱器27的通電與送風單元24、洗衣兼脫水槽7的旋轉，結束熱風處理步驟，實行洗衣步驟(S113)。洗衣步驟，係與清洗一般洗衣物的情況相同，雖未詳細說明，但簡單說是依序進行：將水與洗衣精供給至外槽8內，使洗衣兼脫水槽7旋轉的洗滌；在脫水後將水供給至外槽內，使洗衣兼脫水槽7旋轉的沖洗(通常進行兩次)；使洗衣兼脫水槽7高速旋轉的脫水。 When the elapsed time after the heater 27 is energized is, for example, T+30 minutes or more (S112D), the energization of the heater 27 and the rotation of the blower unit 24 and the washing and dewatering tank 7 are stopped, the hot air processing step is terminated, and the washing step is performed ( S113). The washing step is the same as the case of cleaning the general laundry. Although not described in detail, it is simply carried out in sequence: the water and the laundry detergent are supplied into the outer tank 8, and the washing and dewatering tank 7 is rotated for washing; Thereafter, water is supplied to the outer tank, and the washing and dewatering tank 7 is rotated (usually twice); and the washing and dewatering tank 7 is rotated at a high speed.

洗滌或沖洗的水會進入洗衣物內部，使內部塵蟎的糞便溶於水而被洗掉。且，塵蟎的屍體係被洗衣或脫水中的機械作用給粉碎，且與進入洗衣物內部的水一起被排除至洗衣物外。又，脫水，在設定有洗衣烘乾行程的情況，以短時間結束亦可。且，在熱風處理步驟(S112)中不只是洗衣物，洗衣兼脫水槽7或外槽8等之零件亦會被加溫，故在洗衣步驟(S113)的洗滌所供水的水會被洗衣物或零件給加溫而使水溫上昇。於洗衣物(被子或毛毯)的表面，係與皮垢或頭皮屑等一起附著有皮脂髒污，但該等容易以較高的水溫來去除，有著洗衣物的洗淨效果較高的優點。 The washed or rinsed water will enter the interior of the laundry, allowing the internal dust mites to dissolve in the water and be washed away. Moreover, the dust corpse system is pulverized by mechanical action in the laundry or dehydration, and is excluded from the laundry together with the water entering the inside of the laundry. Further, dehydration may be completed in a short time when the laundry drying process is set. Moreover, in the hot air treatment step (S112), not only the laundry, but also the parts such as the washing and dewatering tank 7 or the outer tank 8 are heated, so that the water supplied by the washing in the washing step (S113) is washed. Or the parts are heated to raise the temperature of the water. On the surface of laundry (quilt or blanket), it is attached with sebum or dandruff and other sebum stains, but these are easy to remove with high water temperature, which has the advantage of high washing effect of laundry. .

洗衣步驟結束後，實行烘乾步驟(S114)。烘乾步驟中，首先，以事先決定的時間實行高速脫水。脫水結束後，使送風單元24運轉，對加熱器27通電，一邊使洗衣兼脫水槽7旋轉，一邊對洗衣物吹附溫風。由於在烘乾步驟的洗衣物含有水分，故被溫風加溫的水分會蒸發，成為 高溫多濕的空氣。為了將該水分予以除濕，於水冷除濕機構流通有冷卻水。檢測出烘乾結束後，結束烘乾步驟，並結束運轉。 After the washing step is completed, a drying step (S114) is carried out. In the drying step, first, high-speed dehydration is performed at a predetermined time. After the completion of the dehydration, the blower unit 24 is operated to energize the heater 27, and while the laundry/dewatering tank 7 is rotated, the warm air is blown to the laundry. Since the laundry in the drying step contains moisture, the moisture heated by the warm air evaporates and becomes High temperature and humidity. In order to dehumidify the water, cooling water flows through the water-cooling dehumidification mechanism. After the drying is detected, the drying step is terminated and the operation is ended.

以下說明烘乾結束之檢測方法的一例。在來自洗衣物之水分的蒸發較多時，冷卻水的熱交換量較多，故熱交換後之冷卻水的溫度係比供給溫度還高。隨著烘乾進行，蒸發的水分會減少，冷卻水的熱交換量會變少，故冷卻水的溫度會降低。另一方面，在通過送風通路19後的溫風溫度，係當水分蒸發較多時幾乎為固定，但隨著烘乾進行而使蒸發的水分量減少時會逐漸變高。以溫度感測器34檢測熱交換後之冷卻水的水溫，並以溫度感測器32檢測通過送風通路19後的溫風溫度，藉此可從該兩者所檢測的溫度差來檢測出烘乾的結束。或者，亦可在烘乾過濾器22與送風單元24之間設置濕度感測器，藉由檢測循環之溫風的濕度來檢測出烘乾的結束。 An example of the method of detecting the end of drying will be described below. When the evaporation of moisture from the laundry is large, the amount of heat exchange of the cooling water is large, so the temperature of the cooling water after the heat exchange is higher than the supply temperature. As the drying progresses, the amount of water evaporated will decrease, and the amount of heat exchange of the cooling water will decrease, so the temperature of the cooling water will decrease. On the other hand, the warm air temperature after passing through the air supply passage 19 is almost constant when the water is evaporated a lot, but gradually increases as the amount of moisture evaporated decreases as the drying progresses. The temperature of the cooling water after the heat exchange is detected by the temperature sensor 34, and the temperature of the warm air after passing through the air supply passage 19 is detected by the temperature sensor 32, whereby the temperature difference detected by the two can be detected. The end of drying. Alternatively, a humidity sensor may be disposed between the drying filter 22 and the air blowing unit 24 to detect the end of drying by detecting the humidity of the circulating warm air.

烘乾步驟結束時，洗衣物的溫度，係接近來自前部吹出口30之溫風溫度的溫度。如上述般使溫風的最高溫度成為70℃，故洗衣物的溫度亦上昇至接近70℃。因此，亦具有洗衣物的除菌效果。 At the end of the drying step, the temperature of the laundry is near the temperature of the warm air temperature from the front outlet 30. As described above, the maximum temperature of the warm air is 70 ° C, so the temperature of the laundry also rises to nearly 70 ° C. Therefore, it also has the sterilization effect of laundry.

如以上所述，根據本實施例，藉由在洗衣步驟之前以高溫進行熱風處理步驟，可使毛毯或被子等之成為塵蟎住處的厚洗衣物在短時間內連內部都成為高溫，可使塵蟎死絕。之後，藉由進行洗衣步驟，可將洗衣物內部之塵蟎的屍體或糞便給洗掉。如上述般，可提供洗衣烘乾機，其具 有不只是使毛毯或被子等之表面變乾淨，連內部所棲息的塵蟎或糞便的去除、除菌都能進行之專用的洗衣烘乾行程。 As described above, according to the present embodiment, by performing the hot air treatment step at a high temperature before the washing step, the thick laundry which becomes the dust mites of the felt or the quilt can be made high temperature even in the short time. The dust mites died. Thereafter, by performing the washing step, the corpses or feces of the dust mites inside the laundry can be washed away. As mentioned above, a laundry dryer can be provided, which has There is a dedicated washing and drying process that not only makes the surface of the blanket or quilt clean, but also removes and removes the dust mites or faeces that are inhabited inside.

圖4的動作流程中，係對加熱器27通電之後以經過時間來判斷熱風處理步驟的結束。經過時間，係根據認為溫度上昇最慢的厚洗衣物到達50℃的時間T來設定。但是，洗衣物較薄的情況，洗衣物的溫度會過高，有對洗衣物造成傷害的可能性。在此，為了不使洗衣物的溫度過高，於圖5表示使用溫度感測器之熱風處理步驟(S120)之動作流程的一例。與圖4相同的參考符號，係相同動作故省略說明。 In the operation flow of Fig. 4, the end of the hot air treatment step is judged by the elapsed time after the heater 27 is energized. The elapsed time is set based on the time T at which the thick laundry which is considered to have the slowest temperature rise reaches 50 °C. However, in the case where the laundry is thin, the temperature of the laundry is too high, and there is a possibility of causing damage to the laundry. Here, in order to prevent the temperature of the laundry from being excessively high, an example of the operational flow of the hot air treatment step (S120) using the temperature sensor is shown in FIG. The same reference numerals as in FIG. 4 are denoted by the same operations, and description thereof will be omitted.

從最先對加熱器27的通電停止之後起算，以是否經過既定時間(例如20分)來分歧處理(S123)。在經過時間超過20分的情況實行結束處理(S130)，並結束熱風處理步驟。結束處理S130，係實行停止對加熱器27的通電、送風單元24與洗衣兼脫水槽7之旋轉的停止。在經過時間為20分以內的情況則進入至S124。 From the first after the energization of the heater 27 is stopped, it is divided (S123) by whether or not a predetermined time (for example, 20 minutes) has elapsed. When the elapsed time exceeds 20 minutes, the end processing is performed (S130), and the hot air processing step is ended. When the process S130 is completed, the energization of the heater 27 and the stop of the rotation of the blower unit 24 and the washing and dewatering tank 7 are stopped. When the elapsed time is within 20 minutes, the process proceeds to S124.

以溫度感測器31的檢測溫度是否為例如閥值78℃以上來分歧處理(S124)。在78℃以上的情況，使送風單元24持續運轉，並停止加熱器27的通電(S131)，在通電停止後經過既定時間(例如5分鐘)後(S132)，回到S112C對加熱器通電。閥值78℃，係為了防止對洗衣物吹拂高溫溫風導致洗衣物受到傷害來設定。藉由停止對加熱器27的通電並使送風單元24運轉，來使循環空氣的溫度 下降。 The difference is detected by whether or not the detected temperature of the temperature sensor 31 is, for example, a threshold value of 78 ° C or higher (S124). When the temperature is 78 ° C or higher, the blower unit 24 is continuously operated, and the energization of the heater 27 is stopped (S131). After a predetermined time (for example, 5 minutes) elapses after the energization is stopped (S132), the process returns to S112C to energize the heater. The threshold value is 78 ° C, which is set to prevent the laundry from being damaged by the high temperature and warm wind blowing on the laundry. The temperature of the circulating air is made by stopping the energization of the heater 27 and operating the blower unit 24 decline.

以溫度感測器32的檢測溫度是否超過例如閥值50℃來分歧處理(S125)。在未達50℃的情況，回到S112C對加熱器27通電。在50℃以上的情況則進入至S126。 The difference is processed (S125) with whether the detected temperature of the temperature sensor 32 exceeds, for example, a threshold of 50 °C. In the case where the temperature is less than 50 ° C, the heater 27 is energized back to S112C. In the case of 50 ° C or more, the process proceeds to S126.

以熱風處理步驟開始之後的時間是否經過閥值(例如90分)來分歧處理(S126)。在經過90分的情況，實行結束處理(S130)來結束熱風處理步驟。圖5的動作流程，係以溫度來判斷熱風處理步驟的結束。但是，依據情況，有著成為無限迴圈而導致熱風處理步驟不會結束的可能性。在此，使熱風處理步驟的最長時間在本實施例中設為90分，當超過該閥值時，強制結束熱風處理步驟。又，該最長時間，係設定成即使是在最惡劣條件(在以難以加溫洗衣物的低溫且烘乾過濾器堵塞導致風量降低的情況)，亦能使洗衣物在50℃以上保持20分鐘以上即可。 Whether or not the time after the start of the hot air treatment step passes through a threshold (for example, 90 minutes) is diverged (S126). When 90 minutes have elapsed, the end processing (S130) is executed to end the hot air processing step. The operation flow of Fig. 5 determines the end of the hot air treatment step by temperature. However, depending on the situation, there is a possibility that the hot air processing step will not end because it becomes an infinite loop. Here, the maximum time for the hot air treatment step is set to 90 minutes in the present embodiment, and when the threshold value is exceeded, the hot air treatment step is forcibly terminated. Moreover, the longest time is set so that the laundry can be kept at 50 ° C or more for 20 minutes even in the worst conditions (in the case where it is difficult to warm the laundry at a low temperature and the drying filter is clogged and the air volume is lowered). More than that.

經過時間為90分以下的情況，持續運轉送風單元24，並停止對加熱器27的通電(S127)。 When the elapsed time is 90 minutes or less, the air blowing unit 24 is continuously operated, and the energization of the heater 27 is stopped (S127).

從最先對加熱器27的通電停止之後起算，以是否經過20分來分歧處理(S128)。在經過時間超過20分的情況，實行結束處理(S130)，並結束熱風處理步驟，在20分以內的情況，則進入S129。 From the first after the energization of the heater 27 is stopped, the divergence processing is performed by whether or not 20 minutes have elapsed (S128). When the elapsed time exceeds 20 minutes, the end processing is executed (S130), and the hot air processing step is ended. If the elapsed time is within 20 minutes, the process proceeds to S129.

以溫度感測器32的檢測溫度是否未達例如閥值45℃來分歧處理(S129)。在45℃以上的情況，回到S128，不對加熱器27通電並繼續送風。在未達45℃的情況，則回到階段S112C並對加熱器27通電。 The difference is detected by whether or not the detected temperature of the temperature sensor 32 has not reached, for example, a threshold value of 45 ° C (S129). In the case of 45 ° C or more, the process returns to S128, and the heater 27 is not energized and the air supply is continued. In the case where the temperature is less than 45 ° C, the process returns to the stage S112C and the heater 27 is energized.

說明本動作流程之基本的思考邏輯。本實施例中，在S125當溫度感測器32的檢測溫度成為50℃以上時，洗衣物的溫度其最低的部份也有55~60℃，是足以讓塵蟎死絕的溫度。在此，於S127停止對加熱器27的通電，使送風單元24運轉，而讓加溫過的溫風循環。因此，循環之溫風的溫度會逐漸降低，因洗衣物或洗衣兼脫水槽7或外槽8的顯熱，而不會使洗衣物的溫度急遽下降，即使不對加熱器27通電，亦可在50℃以上維持20分鐘以上。在此，從最先對加熱器27的通電停止之後起算，經過20分後(S128)結束熱風處理步驟。亦即，在S127的時間點，洗衣物的溫度成為50℃以上，在從這算起經過20分的時間點結束熱風處理步驟S120的話，因為洗衣物係在50℃以上的溫度維持20分鐘以上，故可使塵蟎完全死絕。如上述般，藉由在熱風處理步驟的途中停止對加熱器27的通電，不必使用多餘的電力，便可將洗衣物的溫度維持在50℃以上。且，洗衣物的溫度不會上昇至必要以上，故不會對洗衣物造成傷害。 Explain the basic thinking logic of this action flow. In the present embodiment, when the detected temperature of the temperature sensor 32 becomes 50 ° C or higher at S125, the lowest temperature of the laundry is 55 to 60 ° C, which is a temperature sufficient for the dust mites to die. Here, the energization of the heater 27 is stopped at S127, the blower unit 24 is operated, and the warmed warm air is circulated. Therefore, the temperature of the circulating warm air is gradually lowered, and the sensible heat of the laundry or the washing and dewatering tank 7 or the outer tank 8 does not cause the temperature of the laundry to drop sharply, even if the heater 27 is not energized, Maintain at 50 ° C or above for more than 20 minutes. Here, from the first after the energization of the heater 27 is stopped, the hot air treatment step is terminated after 20 minutes (S128). In other words, at the time of S127, the temperature of the laundry becomes 50 ° C or higher, and when the hot air treatment step S120 is completed at the time of 20 minutes from this, the laundry is maintained at a temperature of 50 ° C or more for 20 minutes or more. Therefore, the dust mites can be completely dead. As described above, by stopping the energization of the heater 27 in the middle of the hot air treatment step, the temperature of the laundry can be maintained at 50 ° C or higher without using unnecessary electric power. Moreover, the temperature of the laundry does not rise above the necessary level, so it does not cause damage to the laundry.

又，通常動作中，在S129不會有溫度感測器32的檢測溫度未達45℃的情況。但是，若因某種原因導致循環空氣的溫度降低的情況，為了防止洗衣物溫度未達50℃，會再次使加熱器27通電。 Further, in the normal operation, the detection temperature of the temperature sensor 32 does not reach 45 ° C in S129. However, if the temperature of the circulating air is lowered for some reason, the heater 27 is energized again in order to prevent the laundry temperature from reaching 50 °C.

以上說明之溫度的閥值僅為一例，只要依據溫度感測器的設置位置或洗衣烘乾機的構造等來適當設定即可。 The threshold value of the temperature described above is only an example, and may be appropriately set depending on the installation position of the temperature sensor or the structure of the washing and drying machine.

本實施例中，雖以滾筒式洗衣烘乾機為例來說明，但 亦可為洗衣兼脫水槽的旋轉軸為大致垂直的直立式洗衣烘乾機。直立式洗衣烘乾機的情況係與滾筒式洗衣烘乾機的構造不同，衣物投入口係開口於洗衣兼脫水槽上部，且洗衣兼脫水槽係垂直設置，成為繞著垂直軸旋轉。且，於洗衣兼脫水槽的底部設有攪拌翼。通常，在洗滌或沖洗時，來自驅動馬達的旋轉係透過遊星齒輪減速機構傳達至攪拌翼，使攪拌翼旋轉。於脫水時，來自驅動馬達的旋轉係直接傳達給洗衣兼脫水槽，使洗衣兼脫水槽與攪拌翼成為一體來旋轉。因此，具備著在洗滌、沖洗時與脫水時切換驅動馬達之動力傳達經路的離合器機構。 In this embodiment, although the drum type washing and drying machine is taken as an example, It can also be a vertical vertical washing and drying machine whose rotating shaft of the washing and dewatering tank is substantially vertical. In the case of the upright washing and drying machine, unlike the structure of the drum type washing and drying machine, the laundry input opening is opened in the upper part of the washing and dewatering tank, and the washing and dewatering tank is vertically disposed to rotate about the vertical axis. Further, a stirring wing is provided at the bottom of the washing and dewatering tank. Generally, during washing or rinsing, the rotation from the drive motor is transmitted to the agitating blades through the planetary gear reduction mechanism to rotate the agitating blades. At the time of dehydration, the rotation from the drive motor is directly transmitted to the washing and dewatering tank, and the washing and dewatering tank is integrated with the stirring blade to rotate. Therefore, there is provided a clutch mechanism that switches the power transmission path of the drive motor during washing, rinsing, and dehydration.

過敏原去除行程的情況，洗衣物為毛毯或被子等較大者，若在洗滌或沖洗時使攪拌翼旋轉的話，與旋轉翼接觸的部分會受傷。因此，在熱風處理步驟、洗衣步驟、烘乾步驟，均使洗衣兼脫水槽與攪拌翼成為一體來旋轉。關於過敏原去除行程的動作流程，與滾筒式洗衣烘乾機相同，故省略說明，但可得到相同的效果。 In the case of the allergen removal stroke, the laundry is a larger one such as a blanket or a quilt, and if the stirring blade is rotated during washing or rinsing, the portion in contact with the rotary wing may be injured. Therefore, in the hot air treatment step, the washing step, and the drying step, the washing and dewatering tank and the stirring blade are integrated to rotate. Since the operation flow of the allergen removal stroke is the same as that of the drum type washing and drying machine, the description thereof will be omitted, but the same effect can be obtained.

且，作為除濕方式雖以水冷除濕方式為例進行了說明，但亦可為空冷除濕方式或排氣除濕方式。空冷除濕方式之情況的動作流程，係與圖4或圖5相同。 Further, although the water-cooling dehumidification method has been described as an example of the dehumidification method, it may be an air-cooling dehumidification method or an exhaust dehumidification method. The operation flow in the case of the air cooling dehumidification method is the same as that of FIG. 4 or FIG. 5.

排氣除濕方式的情況，係以送風單元吸取外氣，並以由加熱器加熱過的溫風來加溫洗衣物，將加溫過洗衣物的溫風排氣至機外。因此，必須經常加熱外氣，故與水冷除濕方式的循環方式相比，難以使洗衣物的溫度上昇。且，在洗衣物的溫度成為50℃以上的時間點停止加熱器的通 電時，會成為將外氣吹向洗衣物，會一口氣使洗衣物的溫度降低。在此，排氣除濕方式中，在洗衣物的溫度到達大致50℃為止前，係使加熱器以強模式運轉來加速洗衣物的溫度上昇，之後，將加熱器切換成弱模式，藉此將洗衣物的溫度維持在50℃以上即可。如此一來，可與水冷除濕方式般的溫風循環方式同樣地實現過敏原去除效果。 In the case of the exhaust dehumidification method, the air is sucked by the air blowing unit, and the warm air heated by the heater is used to warm the laundry, and the warm air heated by the laundry is exhausted to the outside of the machine. Therefore, it is necessary to heat the outside air frequently, so that it is difficult to raise the temperature of the laundry as compared with the circulation method of the water-cooling and dehumidifying method. And, when the temperature of the laundry becomes 50 ° C or more, the heater is stopped. When it is electricity, it will become the air blowing to the laundry, which will lower the temperature of the laundry. Here, in the exhaust dehumidification system, before the temperature of the laundry reaches approximately 50 ° C, the heater is operated in a strong mode to accelerate the temperature rise of the laundry, and then the heater is switched to the weak mode, thereby The temperature of the laundry can be maintained above 50 °C. In this way, the allergen removal effect can be achieved in the same manner as the warm air circulation method like the water-cooling dehumidification method.

以上，作為烘乾的熱源舉出使用加熱器的例子，但亦可為使用熱泵式者。 Although an example in which a heater is used as the heat source for drying is mentioned above, it is also possible to use a heat pump type.

圖6為表示搭載有熱泵式之熱源的滾筒式洗衣烘乾機之一實施例的外觀圖。將框體的一部切斷來了解內部構造。與圖1、圖2相同的參考符號，係表示相同部分故省略說明。 Fig. 6 is an external view showing an embodiment of a drum type washing and drying machine equipped with a heat pump type heat source. Cut one part of the frame to understand the internal structure. The same reference numerals as in FIGS. 1 and 2 denote the same portions, and description thereof will be omitted.

在框體1的背面內側於縱方向設有送風風道19，送風風道下部係以橡膠製的蛇腹管來連接於設在外槽8之背面下方的吸氣口。送風風道19的上部，係連接於過濾器風道35，該過濾器風道35係於上下方向設置在框體1內的上部後側。於過濾器風道35，***有抽出式的烘乾過濾器。於過濾器風道35的下游側設置有蒸發器62，於其下游側連接有吸氣風道38。吸氣風道38的另一端係連接於送風單元24的吸氣口。 A blower duct 19 is provided on the inner side of the back surface of the casing 1 in the longitudinal direction, and a lower portion of the blower duct is connected to an intake port provided below the back surface of the outer tub 8 by a rubber bellows. The upper portion of the air supply duct 19 is connected to the filter duct 35, and the filter duct 35 is provided on the upper rear side of the casing 1 in the vertical direction. A suction type drying filter is inserted into the filter duct 35. An evaporator 62 is provided on the downstream side of the filter duct 35, and an intake duct 38 is connected to the downstream side. The other end of the intake duct 38 is connected to the intake port of the blower unit 24.

送風單元27，係由驅動用的馬達25、風扇葉輪、風扇殼24a所構成。於風扇殼24a內藏有凝縮器63，加熱從風扇葉輪所送出的空氣。送風單元24係連接於溫風風道28。溫風風道28，係透過橡膠製的蛇腹管28a、蛇腹管接 頭29，而連接於設在外槽蓋8a的前部吹出口30。 The blower unit 27 is composed of a motor 25 for driving, a fan impeller, and a fan case 24a. A condenser 63 is housed in the fan casing 24a to heat the air sent from the fan impeller. The air blowing unit 24 is connected to the warm air duct 28 . The warm air duct 28 is made of a rubber bellows tube 28a and a bellows tube joint. The head 29 is connected to the front air outlet 30 provided in the outer tank cover 8a.

壓縮機61，係設置在框體1背面下部的角落部。從壓縮機61拉出的冷媒配管，係連接成從凝縮器63經過蒸發器62而回到壓縮機61。在凝縮器63與蒸發器62之間的冷媒配管設置膨脹機構64。 The compressor 61 is provided at a corner portion of the lower portion of the back surface of the casing 1. The refrigerant piping pulled out from the compressor 61 is connected to return from the condenser 63 to the compressor 61 via the evaporator 62. The refrigerant pipe between the condenser 63 and the evaporator 62 is provided with an expansion mechanism 64.

熱泵循環的冷媒流動係如以下所述。將以壓縮機61所壓縮的高溫高壓氣體在凝縮器63與空氣進行熱交換。之後將以膨脹機構64減壓過的冷媒在蒸發器62蒸發，使低壓氣體回到壓縮機61。在此於蒸發器62使冷媒蒸發之際，通過過濾器風道35的多濕空氣會被冷卻除濕，並在凝縮器63被再次加熱。 The refrigerant flow of the heat pump cycle is as follows. The high temperature and high pressure gas compressed by the compressor 61 is heat-exchanged with the air in the condenser 63. Thereafter, the refrigerant decompressed by the expansion mechanism 64 is evaporated in the evaporator 62 to return the low pressure gas to the compressor 61. Here, when the evaporator 62 evaporates the refrigerant, the humid air passing through the filter duct 35 is cooled and dehumidified, and is again heated in the condenser 63.

烘乾運轉時的空氣流動係如下所述。使送風單元24運轉，並使熱泵的壓縮機61運轉藉此使凝縮器63發熱，從前部吹出口30對洗衣兼脫水槽7內吹入溫風，吹拂潮濕的衣物，加溫衣物使水分從衣物蒸發。成為高溫多濕的空氣，係從設在洗衣兼脫水槽7的貫通孔流向外槽8，而從吸氣口被吸入送風風道19，於送風風道19由下往上流動，進入過濾器風道35。通過設在過濾器風道35的網狀過濾器而將棉屑去除後，進入蒸發器62。高溫多濕的空氣係與低溫的蒸發器62接觸藉此被冷卻除濕，成為乾燥的低溫空氣而進入吸氣風道38，被吸往送風單元24。然後，在高溫的凝縮器63被再次加熱，並吹入洗衣兼脫水槽7內來循環。 The air flow during the drying operation is as follows. The blower unit 24 is operated, and the compressor 61 of the heat pump is operated to heat the condenser 63, and the warm air is blown into the washing and dewatering tank 7 from the front air outlet 30, the wet laundry is blown, and the clothes are warmed to remove moisture. The clothes evaporate. The high-temperature and high-humidity air flows from the through hole provided in the washing and dewatering tank 7 to the outer tank 8, and is sucked into the blower duct 19 from the intake port, and flows from the bottom to the top of the blower duct 19 to enter the filter. Wind tunnel 35. The cotton swarf is removed by the mesh filter provided in the filter duct 35, and then enters the evaporator 62. The high-temperature and humid air is brought into contact with the low-temperature evaporator 62 to be cooled and dehumidified, becomes dry low-temperature air, enters the intake air passage 38, and is sucked to the air blowing unit 24. Then, the condenser 63 at a high temperature is heated again and blown into the washing and dewatering tank 7 to circulate.

熱泵式，其基本的動作流程亦與圖4所示者相同。熱 泵式在與加熱器式相比之下，使熱泵循環成立需要時間，故溫風的溫度上昇較慢。在此，於熱風處理步驟中，在使溫風的溫度到達既定溫度，例如到達60~70℃之前，維持較高的壓縮機61之旋轉。藉此，可用比較短的時間來使洗衣物的溫度成為50℃以上。之後使壓縮機61的旋轉降低來調整發熱量。這是因為，熱泵循環，係當停止壓縮機61時，即使再次起動壓縮機亦無法馬上送出溫風，故在溫風成為既定溫度之後，使壓縮機61以低速來持續壓縮機的運轉較佳。 The basic operation flow of the heat pump type is also the same as that shown in FIG. heat Compared with the heater type, the pump type takes time to make the heat pump cycle, so the temperature of the warm air rises slowly. Here, in the hot air treatment step, the rotation of the compressor 61 is maintained high before the temperature of the warm air reaches a predetermined temperature, for example, before reaching 60 to 70 °C. Thereby, the temperature of the laundry can be made 50 ° C or more in a relatively short period of time. Thereafter, the rotation of the compressor 61 is lowered to adjust the amount of heat generation. This is because the heat pump cycle is such that when the compressor 61 is stopped, even if the compressor is restarted, the warm air cannot be immediately sent out. Therefore, after the warm air reaches a predetermined temperature, the compressor 61 is preferably operated at a low speed to continue the operation of the compressor. .

於熱泵方式，亦可將洗衣物的溫度在50℃以上保持20分鐘以上，故與加熱器式同樣地可使塵蟎死絕，之後，藉由進行洗衣、烘乾，可去除塵蟎或塵蟎的糞便等之過敏原。且，由於熱泵式在與加熱器式相比之下，能夠以較低的輸入而有較高的加熱能力，故當然節能性較優異。 In the heat pump mode, the temperature of the laundry can be maintained at 50 ° C or higher for more than 20 minutes, so that the dust mites can be eliminated in the same manner as the heater type, and then the dust mites or dust can be removed by washing and drying. An allergen such as sputum. Moreover, since the heat pump type can have a higher heating capacity with a lower input than the heater type, it is of course excellent in energy saving.
