Abstract

The invention discloses a washing and drying unit with function of adjusting heat pump load and a drying control method for the washing and drying unit. The washing and drying unit comprises a drum, a heat pump module, a drying air duct, a low-temperature auxiliary air duct, an air duct switching mechanism and a bypass air way, wherein the drum and the heat pump module are communicated with each other through the drying air duct, the low-temperature auxiliary air duct is capable of sending hot air generated by the heat pump module to an evaporator operational environment for the purpose of heating, the air duct switching mechanism is used for controlling the hot air generated by the heat pump module to enter the drying air duct and/or the low-temperature auxiliary air duct, and the bypass air way communicated with the outside is disposed on the drying air duct and between an air outlet of the drum and the heat pump module. When drying starts, a heat pump of the washing and drying unit is used to heat and send the hot air into the heat pump module to rise the evaporation temperature of refrigerant in an evaporator by the aid of the low-temperature auxiliary air duct. In mid-late drying, the air duct switching mechanism controls the bypass air way to suck in external air or exhaust part of hot humid air inside the drying air duct, so that operational load of a compressor is reduced. By the washing and drying unit and the drying control method, the problem of drying impact from environmental temperature is solved, drying time is saved, and drying efficiency is improved.

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...
