Description

本発明は、洗濯物を洗濯する洗濯機に関するものである。   The present invention relates to a washing machine for washing laundry.

洗濯機に乾燥機能を設けて、洗濯機能と乾燥機能とを任意に選択して洗濯から乾燥までを自動的に実施する洗濯乾燥機が知られている（例えば、特許文献１参照）。   2. Description of the Related Art A washing / drying machine is known in which a drying function is provided in a washing machine, and a washing function and a drying function are arbitrarily selected and washing to drying is automatically performed (for example, see Patent Document 1).

図９は、従来の洗濯乾燥機を示す断面図である。   FIG. 9 is a cross-sectional view showing a conventional washing / drying machine.

図９において、筐体１内に外槽３がサスペンション２により防振支持されている。外槽３内に内槽４が配設され、内槽４の底部には、攪拌翼６が設けられ、内槽４及び攪拌翼６はクラッチ９による駆動切換によりモータ８によって個別に回転駆動される。筐体１の上部に設けられた外蓋６３を開き、外槽３の上部開口を閉じる外槽カバー６４に設けられた内蓋６５を開いて内槽４内に洗濯物及び洗剤を投入する。内槽４内に注水してモータ８により攪拌翼６を回転させることにより洗濯行程が実施する。   In FIG. 9, the outer tub 3 is supported in a vibration-proof manner by a suspension 2 in the housing 1. An inner tub 4 is disposed in the outer tub 3, and a stirring blade 6 is provided at the bottom of the inner tub 4. The inner tub 4 and the stirring wing 6 are individually rotated and driven by a motor 8 by driving switching by a clutch 9. The The outer lid 63 provided on the upper portion of the housing 1 is opened, the inner lid 65 provided on the outer tub cover 64 that closes the upper opening of the outer tub 3 is opened, and laundry and detergent are put into the inner tub 4. The washing process is performed by pouring water into the inner tub 4 and rotating the stirring blade 6 by the motor 8.

洗濯行程が終了すると、内槽４内の水を排水した後、モータ８により内槽４を回転させて遠心力により洗濯物に含まれる水を内槽４の周壁に形成された多数の小孔から排出する脱水行程が実施される。脱水行程が終了すると、注水、攪拌、排水、脱水を行うすすぎ行程が実施されることにより洗濯の行程は終了する。   After the washing process is completed, the water in the inner tub 4 is drained, and then the inner tub 4 is rotated by the motor 8 so that water contained in the laundry is formed in the peripheral wall of the inner tub 4 by centrifugal force. A dehydration process is carried out. When the dehydration process is completed, the washing process is completed by performing a rinsing process of water injection, stirring, drainage, and dehydration.

この洗濯行程に加えて乾燥行程が実施できるように、内槽４内から外槽３内に通じて熱交換器１２、循環ファン１８、ヒータ１９を経て再び内槽４内に戻る空気循環経路が形成されている。攪拌翼６によって洗濯物を攪拌しながら、ヒータ１９により加熱された温風を循環ファン１８により内槽４内に送給すると、洗濯物の水分を奪った温風は、内槽４の小孔から外槽３内に出て熱交換器１２内を通過することにより、水分を含む温風は冷却されて水分の結露が生じて除湿される。除湿された空気は、循環ファン１８により再びヒータ１９に送られて加熱され、内槽４内に送給される。この空気循環を繰り返すことにより洗濯物の乾燥がなされる。   In order to be able to carry out a drying process in addition to this washing process, there is an air circulation path that passes from the inner tub 4 to the outer tub 3 and then returns to the inner tub 4 through the heat exchanger 12, the circulation fan 18, and the heater 19. Is formed. When the warm air heated by the heater 19 is fed into the inner tub 4 by the circulation fan 18 while the laundry is being stirred by the stirring blade 6, the hot air deprived of the moisture of the laundry becomes a small hole in the inner tub 4. The hot air containing moisture is cooled and dehydrated by dehydration of moisture by passing through the heat exchanger 12 through the heat exchanger 12. The dehumidified air is sent again to the heater 19 by the circulation fan 18 to be heated and fed into the inner tank 4. The laundry is dried by repeating this air circulation.

上記のように洗濯機に乾燥機能を設けて洗濯乾燥機としたとき、外槽３の上部開口を閉じる外槽カバー６４及び内蓋６５が設けられている。外槽カバー６４及び内蓋６５は、内蓋６５の軸を外槽カバー６４の軸受部に軸支している。   When the washing machine is provided with a drying function as described above to provide a washing and drying machine, the outer tub cover 64 and the inner lid 65 that close the upper opening of the outer tub 3 are provided. The outer tub cover 64 and the inner lid 65 pivotally support the shaft of the inner lid 65 on the bearing portion of the outer tub cover 64.
