The cabin 210 is provided therein with a temperature detector 400 for detecting the temperature of the compressor 250; the cabinet 210 is communicated with the washing machine 100 through a first air duct 300, and a first fan 500 is disposed in the first air duct 300. One end of the first air duct 300 is communicated with the cabinet 210, and the other end is communicated with an inner tub of the washing machine 100. Specifically, the tub of the washing machine 100 refers to a place where the washing machine 100 holds laundry, such as a drum of the drum washing machine 100. The first fan 500 is used to power the flow of air, and can send the hot air of the cabinet 210 into the washing machine 100.
Specifically, the cabin 210 may be an independent box, and the compressor 250 is disposed in the cabin 210, so that on one hand, protection can be formed for the compressor 250, and on the other hand, heat generated during the operation of the compressor 250 is collected, so that waste heat of the compressor 250 is conveniently utilized. The application aims to reduce the surface temperature of the compressor 250 by recycling the waste heat of the compressor 250, thereby being beneficial to heat dissipation of the compressor 250 and prolonging the service life of the compressor 250.
The heat pump washing machine collects the residual heat generated during the operation of the compressor 250 through the cabinet 210, and transmits the residual heat to the washing machine 100 by using the air duct and the blower to dry laundry. The waste heat of the compressor 250 is fully utilized, the energy is saved, and the drying efficiency of clothes is improved; but also can reduce the temperature of the compressor 250 and prolong the service life of the compressor 250.

The condenser 220 is provided with a condensing fan 230, and an air outlet of the condensing fan 230 is communicated with the washing machine 100 through a second air pipe 240. The normal temperature air exchanges heat with the condenser 220 at the condenser 220 to become high temperature air. The high temperature air is sent into the washing machine 100 by the condensing fan 230 through the second air duct 240, and the laundry is dried. In practical applications, the hot air in the second duct 240 plays a primary role in drying, and the hot air in the cabin 210 plays a role in assisting drying. Namely, the second air duct 240 is a main air duct, and the first air duct 300 is an auxiliary drying air duct. Wherein, one end of the first air duct 300 is mutually communicated with the second air duct 240, one end of the second air duct 240 is communicated with the washing machine 100, and the air flow in the first air duct 300 enters the washing machine 100 after entering the second air duct 240. In another embodiment, the first air duct 300 may also be directly connected to the washing machine, but not connected to the second air duct 240.
Further, the temperature detectors 400 are provided in the machine room 210 in 2 to 3. A plurality of temperature detectors 400 detect temperatures at different locations of the compressor 250. The control system of the washing and caring machine judges the temperature of the compressor 250 according to the temperature data fed back by the different temperature detectors 400, and determines whether the surface temperature of the compressor 250 is too high. The temperature of the compressor 250 is detected by using a plurality of temperature detectors 400, so that the accuracy of temperature detection is ensured, and the detected data caused by the fault of a certain temperature detector 400 can be prevented from being wrong.
Further, a heat dissipation fan 260 is further disposed in the machine cabin 210, the heat dissipation fan 260 is disposed towards the compressor 250, and the heat dissipation fan 260 is electrically connected with the temperature detector 400. It should be noted that, the air outlet direction of the heat dissipation fan 260 is the same as the air outlet direction of the first fan 500, and the heat dissipation fan 260 can send the heat generated by the compressor 250 into the washing machine 100 through the first air pipe 300.
More specifically, the heat dissipation fan 260 is fixed to the cabinet 210 through a shock absorbing damper 2601.
The heat dissipation fan 260 is used for performing auxiliary heat dissipation on the compressor 250. If the residual heat of the compressor 250 is utilized, the surface temperature of the compressor 250 is still too high, and the heat dissipation fan 260 needs to be started to dissipate heat of the compressor 250, so that the compressor 250 is prevented from being damaged due to the too high temperature of the compressor 250. If the first fan 500 is not started, the surface temperature of the compressor 250 is too high, and the heat dissipation fan 260 is started to dissipate heat of the compressor 250. The damping pad 2601 can reduce the influence of the operation vibration of the compressor 250 on the heat dissipation fan 260, and prolong the service life of the heat dissipation fan 260.
In a more preferred embodiment, a gas filter 600 is provided in the air duct. Still further, the gas filter 600 includes a filtering section 610 and a dehumidifying section 620 that are sequentially connected, the filtering section 610 includes a first filtering layer 6101 and a second filtering layer 6102 that are disposed in parallel, and the second filtering layer 6102 is disposed near the dehumidifying section 620 along the flowing direction of the gas.
The air filter 600 is used for filtering the hot air drawn from the cabinet 210 by the first fan 500, ensuring the cleanliness of the hot air and preventing the hot air from contaminating the laundry. The first filtering layer 6101 and the second filtering layer 6102 have different filtering effects, and the first filtering layer 6101 may be a filter screen for filtering dust in hot air. The first filtering layer 6101 may be an activated carbon layer for adsorbing harmful substances in hot air.
