Abstract

The invention discloses a control method of an inverter compressor of a heat pump clothing dryer and the heat pump clothing dryer. The heat pump clothing dryer comprises a heat pump clothing drying system comprising a heat pump module comprising the inverter compressor, a condenser, a throttling device and an evaporator, or further comprises a fan used for decreasing the temperature of the surface of the inverter compressor to adjust the load. In the clothing drying process, the operating frequency of the inverter compressor is controlled segmentally; the method includes compressor frequency rising control, compressor frequency inverting control and clothing drying finish determination. If a set clothing drying condition is not achieved after detection, the processes of compressor frequency inverting control and clothing drying finish determination are repeated circularly. The compressor frequency rising control means controlling the inverter compressor to rise the frequency to an ultimate frequency and operate stably; the compressor frequency inverting control means adjusting the operating frequency of the inverter compressor segmentally corresponding to the detection temperature. the control method and the heat pump clothing method have the advantages that drying efficiency is improved, operating efficiency of the inverter compressor is optimized, and service life of the inverter compressor is prolonged.

Description

technical field

[0001] The invention relates to a clothes drying device and a clothes drying control method, in particular to a control method of a frequency conversion compressor of a heat pump clothes dryer and the heat pump clothes dryer by controlling the clothes drying process in stages to reduce energy consumption. Background technique

[0002] The following air circulation channel is arranged in the existing heat pump type clothes drying device: the heated air heated by the condenser in the heat pump cycle system is sent into the drying room containing the clothes, and the moist air which has taken moisture from the clothes is It is sent back to the evaporator for dehumidification, and the dehumidified air is heated by the condenser again and sent to the drying chamber.

[0003] In the drying system of heat pump clothes dryer, the pressure that the compressor system can withstand is the saturation pressure corresponding to the temperature of the refrigerant correspond...
