Abstract

The invention discloses an integrated washing and drying machine with the function of adjusting heat pump load and a drying control method thereof. The integrated washing and drying machine with heat pump includes a drum, a heat pump module, and a drying air duct connecting the drum and the heat pump module, and also includes a clothes dryer that can The hot air generated by the heat pump module passes into the low-temperature auxiliary air duct for heating the working environment of the evaporator, and the air duct switching mechanism that controls the hot air generated by the heat pump module to pass into the drying air duct and / or the low-temperature auxiliary air duct, the drum air outlet and the heat pump The clothes drying air duct between the modules is provided with a bypass air duct communicating with the outside world. At the beginning of drying, use its own heat pump to heat the hot air into the heat pump module through the low-temperature auxiliary air channel to increase the evaporation temperature of the refrigerant in the evaporator. In the middle and later stages of drying, the air channel switching mechanism controls the bypass air channel to suck in external air or discharge dry clothes Part of the hot and humid air inside the air duct reduces the workload of the compressor. The invention solves the problem of the influence of ambient temperature on drying clothes, saves drying time and improves drying efficiency.

Description

technical field [0001] The invention relates to a heat pump washing and drying machine and a control method thereof, in particular to a washing and drying machine with the function of adjusting heat pump load and a drying control method thereof. 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] Chinese Patent Application No. 200610153406.9 discloses a clothes drying device capable of stabilizing the operation of a heat pump generating drying air circulating between the drying chamber and the heat pump. Among them, the air heated by the heater in the heat pum...
