Clothes washing and drying machine with heat pump, heat pump, and application of heat pump in clothes washing and drying machine with heat pump

Abstract

The invention discloses a clothes washing and drying machine with a heat pump, a heat pump unit and application of the heat pump in the clothes washing and drying machine with the heat pump, wherein the heat pump unit comprises a shell, an evaporator fixed in the shell, and a condenser fixed in the shell, the shell is provided with a first accommodating cavity, a second accommodating cavity communicated with the first accommodating cavity, and drainage holes in the bottom of the first accommodating cavity, the evaporator is located in the first accommodating cavity, the condenser is located in the second accommodating cavity, the shell is further provided with a binding opening in a shrinking shape in the height direction, the bottom of the binding opening is higher than the drainage holes, and the first accommodating cavity is communicated with the second accommodating cavity through the binding opening. The clothes washing and drying machine with the heat pump, the heat pump and application of the heat pump in the clothes washing and drying machine with the heat pump have the benefits that the bottom of the binding opening is higher than the drainage holes, so that on one side, the water drainage is facilitated, on the other side, the air processed after the evaporator moves towards the second accommodating cavity from bottom top, therefore, the condensed water is prevented from being brought in, and the energy efficiency is higher.

Description

【Technical field】 [0001] The invention relates to a heat pump washing and drying machine, a heat pump unit and an application thereof, belonging to the field of home appliances. 【Background technique】 [0002] Along with improving constantly of people's living standard, simple washing machine can't satisfy people's requirement more and more. The appearance of the washing and drying machine with drying function has brought great convenience to people's life. [0003] The drying mode of the washer-dryer mainly includes: an electric heating water condensation drying system, an electric heating air condensation drying system, and a heat pump heating system combining evaporator condensation with condenser heating. Compared with the previous two drying modes, heat pump drying can save energy by 40% to 50%, and the drying process does not consume water, so the market application prospect is broad.

AI Technical Summary

Problems solved by technology

But this design has some disadvantages: First, the evaporator and the main drain pump of the heat pump washer-dryer are arranged at the bottom of the machine at the same time, and there is no drop

Such a ventilation pipeline produces a large wind resistance, which is not conducive to the operation of the system, and the relative cost is also high
