Heat pump type clothes dryer

Abstract

The invention relates to a heat pump type clothes dryer which comprises a control system, a refrigeration system and an air circulation system, wherein the refrigeration system consists of a compressor, a condenser, an evaporator and a throttle valve, the air circulation system consists of a clothes drying barrel, an evaporator, an evaporator fan, a condenser, a condenser fan, a humid heat air flow passage, a low-temperature dry air flow passage and a dry air flow passage, the humid heat air flow passage is arranged between the clothes drying barrel and the evaporator, the low-temperature dry air flow passage is arranged between the evaporator and the condenser, the dry air flow passage is arranged between the condenser and the clothes drying barrel, the compressor is a variable-frequency compressor and comprise a first condenser and a second condenser group which are connected in series, and the output end of the first condenser is also provided with a by-pass pipeline so that refrigerants can selectively flow to the throttle valve through the by-pass pipeline. The heat pump type clothes dryer can be used for high temperature dehumidification in high moisture content, can be used for medium temperature dehumidification in low moisture content and has obvious energy saving effect.

Description

technical field [0001] The present invention relates to a device for drying clothes, more specifically, relates to a heat pump type clothes dryer. Background technique [0002] It is very convenient for the family to use a clothes dryer under the conditions of long-term rainy, humid, windy and sandy, outdoor industrial smoke, crowded houses and impermeable clothes. A clothes dryer is a cleaning household appliance that uses hot air to instantly evaporate and dry the moisture in the washed clothes. [0003] Clothes dryers are divided into cabinet type and drum type according to the structural form. The cabinet type machine is to hang the clothes on the hanger in the oven for drying, and has a large capacity; the drum type is to put the clothes directly into the drum, which is larger in volume than the cabinet type. Minor. Clothes dryers are divided into exhaust type and dehumidification type according to the moisture removal method. The exhaust type is to discharge the wate...

AI Technical Summary

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide a heat pump type clothes dryer that can automatically adjust the dehumidification capacity of the system according to the humidity of the fabric, in view of the above-mentioned clothes dryer that cannot achieve high temperature dehumidification when the humidity is large, and low temperature dehumidification when the humidity is low. The drying capacity can be changed to meet the needs of different fabrics and different humidity drying, so as to save energy
