Problems solved by technology

[0007] The above judgment method is not suitable for heat pump dryers, because the working environment temperature of the heat pump dryer has a certain influence on its load. When the ambient temperature is different, the time to run to the maximum load is also different, so the temperature difference is judged within the time range. , there is a possibility of misjudgment

Embodiment Construction

[0037] Such as figure 1 with figure 2 As shown, the heat pump clothes dryer according to the present invention includes a drum 9 and a heat pump system provided below the drum. The hot air generated by the heat pump drying system is guided by the air supply fan 5 into the drum to dry clothes through the drying air duct. The heat pump The clothes drying system includes a heat pump module with a compressor 1, a condenser 2, a throttling device 4, and an evaporator 5, and also includes an auxiliary condensing fan 8 for cooling the surface of the compressor 1 to adjust the load, and the refrigerant circulation pipeline sequentially Connect compressor 1, condenser 2, throttling device 3, evaporator 4 to compressor 1. The condenser 2 is provided with a condenser temperature sensor 7 near the refrigerant outlet, and the condenser temperature sensor 7 detects the temperature of the condenser outlet, and the discharge temperature sensor 6 is arranged near the discharge pipe outlet of...

Abstract

The invention discloses a control method for judging the clogging of the lint filter of a heat pump dryer and the clothes dryer. Whether the lint filter is clogged is judged by detecting the temperature difference between the air entering and leaving the cylinder in a stable working state of the heat pump system, and Prompts the user to clean the lint filter. The heat pump dryer first detects whether the heat pump system has reached a stable working state through the temperature sensors set at three positions, and then detects the temperature difference between the inlet and outlet cylinders, thereby judging whether the lint filter of the heat pump dryer is blocked; Under a stable heat pump system working condition, the heat pump dryer that detects the temperature difference between the inlet and outlet cylinders to determine whether the lint filter of the heat pump dryer is clogged can promptly and quickly determine the blockage of the air duct, remind the user to clean up the lint, and improve product efficiency. Safety, improve drying efficiency and save energy.

Description

technical field [0001] The invention relates to a clothes dryer and a control method for the clothes dryer, in particular to a control method for judging the clogging of the lint filter of the heat pump clothes dryer and the heat pump clothes dryer. 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...
