Washing machine drier employing heat pump as heat source

Abstract

The invention provides a dryer of a washing machine that adopts a heat pump as heat source, more particularly, which relates to a device that uses heat source of a condenser in a heat pump system to heat the air and uses an evaporator in the system as dehumidifying cold source so as to dry clothes. A hot air inlet 23 is arranged at the rear side of an external barrel 21 of the washing machine, a hot air outlet 17 is arranged at the front end of the external barrel 21 of a roller, and an air passage near the hot air outlet 17 is communicated with the hot air inlet 23; additionally, the evaporator 8 is arranged in the air passage which is near the hot air outlet 17, and a set near the hot air inlet 23 is arranged in the air passage. By regulating the internal structure, the scheme of the invention achieves great simplification based on the prior art.

Description

technical field [0001] The present invention relates to a washing machine drying device, in particular, the present invention relates to a method of using the heat source of the condenser in the heat pump system to heat the air, and using the evaporator in the system as the dehumidification cold source to dry the clothes installation. Background technique [0002] CN95120516 discloses a tumble dryer, which includes a refrigerating cycle system and can air-condition the outside air. A drum washing machine, which includes a control device that controls a drive unit so that the drum rotates at a high speed one or more times, thereby dehydrating the laundry at the beginning of drying. [0003] JP2147097 discloses a clothes dryer which uses hot air from an outdoor air conditioner to dry clothes. [0004] But the washing machine with heat pump described in the prior art has the following defects: [0005] (1) Multiple gas circuit valves are used on the air circuit for controlli...

AI Technical Summary

Problems solved by technology

[0005] (1) Multiple gas circuit valves are used on the air circuit for controlling hot air or cold air, resulting in complex structure of the device and inconvenient maintenance;

[0006] (2) The space of the condenser used as the heat source for drying is too small, and when used as an air conditioner, it is inconvenient to dissipate heat, resulting in an increase in the temperature of the condenser, a decrease in efficiency, and a shortened service life;

[0007] (3) The drying hot air is used as the rear air intake, resulting in the line filter being placed on the back of the inner barrel and unable to be cleaned;
