WASHING AND DRYING MACHINE
Document Type and Number:
Japanese Patent JP2017093816
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To achieve energy saving of a drying operation in a washing and drying machine which mounts a heat pump device.SOLUTION: A washing and drying machine 20 includes: a rotary drum 103; an outer tank for including the rotary drum 103; a lint filter 90; a heat pump device; a blower fan 8; and a circulation air passage 17 for connecting these sequentially. The heat pump device is constituted by a refrigerant circuit 16 which sequentially connects a compressor 2, a condenser 3 for releasing the heat of the refrigerant to the air, decompression means 5 and an evaporator 4 for absorbing heat from the air. In the circulation air passage 17, the evaporator 4 and the condenser 3 are arranged from the upstream side of the circulation air, and a communication passage 10 is provided connected to the outside of the circulation air passage 17, in the middle of the circulation air passage leading to the condenser 3 from the evaporator 4. A supply and exhaust air heat exchanger 7 is provided capable of exchanging heat mutually between the exhaust air to the outside of the circulation air passage 17 and supply air to the inside of the circulation air passage 17. With this constitution, the exhaust heat can be recovered, and energy saving can be achieved during a drying operation.SELECTED DRAWING: Figure 3
