Description

また、乾燥対象を収容する乾燥室を多数の開口部が形成された回転ドラムを収容した洗濯槽とし、この洗濯槽の内周面又は外周面に蒸発器を配設した洗濯機一体型に形成することにより、放熱器によって加熱した乾燥用空気を洗濯槽に導くと、洗濯、脱水された衣類から水分を奪い、水分を含んだ乾燥用空気は洗濯槽に配設された蒸発器によって冷却、除湿されるので、乾燥用空気を、放熱器、洗濯槽(乾燥室)、蒸発器に循環させることにより衣類を乾燥させることができ、洗濯機に乾燥機を一体化させた洗濯機一体型ヒートポンプ式乾燥機を構成することができる。 In addition, the drying chamber for containing the object to be dried is a washing tub containing a rotary drum having a large number of openings, and an evaporator is provided on the inner or outer peripheral surface of the washing tub. When the drying air heated by the radiator is introduced to the washing tub, the clothes that have been washed and dewatered are deprived of moisture, and the drying air containing moisture is cooled by the evaporator disposed in the washing tub. Since it is dehumidified, clothes can be dried by circulating drying air to a radiator, a washing tank (drying chamber), and an evaporator, and a washing machine integrated heat pump in which a dryer is integrated with a washing machine. The dryer can be configured.

上記構成において、冷媒は圧縮機1によって圧縮されることにより高温高圧の状態となって放熱器2に流れ、放熱器2でそれを通過する乾燥用空気と熱交換して乾燥用空気を加熱する。放熱器2での熱交換により冷却された冷媒は膨張弁3によって減圧され、低温低圧の状態になって蒸発器4に流れる。前記放熱器2で加熱された高温低湿の乾燥用空気は乾燥室11に流れ、乾燥室11内に収容された乾燥対象5から水分を奪って蒸発器4に流れる。水分を含んだ乾燥用空気は、低温低圧の冷媒が流れる蒸発器4に触れることにより冷却されて含まれた水分が凝縮、除湿される。蒸発器4で冷却され除湿された乾燥用空気は送風ファン6により送風され、空気還流路12から再び放熱器2に送り出される。蒸発器4で乾燥用空気中の水分を凝縮、除湿することにより冷媒は加熱されて再び圧縮機1に送られ、乾燥用空気の加熱、除湿のサイクルが繰り返され、それによって乾燥対象5に対する連続的な乾燥動作が実施される。尚、蒸発器4による冷却、除湿によって発生するドレン水は、図示しない排出経路から外部排出することができる。 In the above configuration, the refrigerant is compressed by the compressor 1 to be in a high temperature / high pressure state and flows to the radiator 2, and the radiator 2 exchanges heat with the drying air passing therethrough to heat the drying air. . The refrigerant cooled by the heat exchange in the radiator 2 is decompressed by the expansion valve 3 to be in a low temperature and low pressure state, and flows to the evaporator 4. The high-temperature low-humidity drying air heated by the radiator 2 flows into the drying chamber 11, removes moisture from the drying target 5 contained in the drying chamber 11, and flows into the evaporator 4. The moisture containing drying air is cooled by touching the evaporator 4 in which a low temperature and low pressure refrigerant flows, and the contained moisture is condensed and dehumidified. The drying air cooled and dehumidified by the evaporator 4 is blown by the blower fan 6 and is again sent out to the radiator 2 from the air return path 12. By condensing and dehumidifying the moisture in the drying air with the evaporator 4 , the refrigerant is heated and sent again to the compressor 1, and the cycle of heating and dehumidifying of the drying air is repeated, whereby continuous for the object to be dried 5 Drying operation is performed. In addition, drain water generated by cooling and dehumidification by the evaporator 4 can be discharged to the outside from a not shown discharge path.

上記構成において、冷媒は圧縮機1によって圧縮されることにより高温高圧の状態となって放熱器2に流れ、放熱器2でそれを通過する乾燥用空気と熱交換して乾燥用空気を加熱する。熱交換により冷却された冷媒は膨張弁3によって減圧され、低温低圧の状態になって蒸発器4に流れる。前記放熱器2で加熱された高温低湿の乾燥用空気は空気還流路16から送風ファン6によって送風されて洗濯/乾燥室15に流入し、回転ドラム7内に収容された乾燥対象5から水分を奪う。回転ドラム7の底面には開口部はなく閉じられているので、回転ドラム7の開口部から洗濯槽8b内に出た水分を含んだ乾燥用空気は、下方の外周面に配設された蒸発器4により冷却されている洗濯槽8bに触れることにより冷却されて含まれた水分が凝縮、除湿される。蒸発器4で冷却され除湿された乾燥用空気は送風ファン6により送風され、空気還流路12から再び放熱器2に送り出される。蒸発器4で乾燥用空気中の水分を凝縮、除湿することにより冷媒は加熱されて再び圧縮機1に送られ、乾燥用空気の加熱、除湿のサイクルが繰り返され、それによって乾燥対象5に対する連続的な乾燥動作が実施される。尚、蒸発器4による冷却、除湿によって発生するドレン水は、図示しない洗濯機の排出経路により外部排出することができる。 In the above configuration, the refrigerant is compressed by the compressor 1 to be in a high temperature / high pressure state and flows to the radiator 2, and the radiator 2 exchanges heat with the drying air passing therethrough to heat the drying air. . The refrigerant cooled by heat exchange is depressurized by the expansion valve 3 to be in a low temperature and low pressure state and flows to the evaporator 4. The high-temperature low-humidity drying air heated by the radiator 2 is blown from the air return path 16 by the blower fan 6 and flows into the washing / drying chamber 15, and moisture is removed from the drying object 5 contained in the rotary drum 7. Take away. Since the bottom of the rotary drum 7 is closed without opening, the drying air containing moisture that has been discharged from the opening of the rotary drum 7 into the washing tank 8b is evaporated on the outer peripheral surface below. Moisture that has been cooled and contained by being touched by the washing tank 8 b cooled by the vessel 4 is condensed and dehumidified. The drying air cooled and dehumidified by the evaporator 4 is blown by the blower fan 6 and is again sent out to the radiator 2 from the air return path 12. By condensing and dehumidifying the moisture in the drying air with the evaporator 4 , the refrigerant is heated and sent again to the compressor 1, and the cycle of heating and dehumidifying of the drying air is repeated, whereby continuous for the object to be dried 5 Drying operation is performed. The drain water generated by the cooling and dehumidification by the evaporator 4 can be discharged to the outside through the discharge path of the washing machine (not shown).

従来技術での熱交換器を循環流路の断面積の大部分を占めるように配置する構成と比較して、本実施形態の構成では乾燥用空気の循環流路の断面積占める熱交換器の面積が減少するので空気抵抗が少なくなり、送風ファンの送風能力を減少させることができ、省エネルギーを図ることができる。また、乾燥対象5から発生する埃による空気循環流路の目詰まりも生じにくくなる。 In comparison with the configuration of arranging the heat exchanger in the prior art so as to occupy most of the cross-sectional area of the circulation passage, the heat exchanger which occupies the cross-sectional area of the circulation passage of the drying air in the configuration of this embodiment Since the area of the air conditioner is reduced, the air resistance is reduced, the air blowing capacity of the air blowing fan can be reduced, and energy saving can be achieved. In addition, clogging of the air circulation flow path due to dust generated from the drying target 5 is less likely to occur.
