Washing and drying integrated machine with front and rear double drying air inlets and control method thereof

Abstract

The invention discloses a washing and drying integrated machine with front and rear double drying air inlets and a control method thereof, and the washing and drying integrated machine comprises a housing, an outer cylinder arranged in the housing, an inner cylinder which is rotatably arranged in the outer cylinder and a heat pump system for drying clothes, wherein the heat pump system comprises a heat pump air inlet and a heat pump air outlet, the front drying air inlet and the rear drying air inlet are respectively arranged above the front part and the rear part of the outer cylinder, a drying air outlet is further arranged above the front part of the outer cylinder, the drying air outlet and the heat pump air inlet are communicated through an air inlet passage, the heat pump air outlet is communicated with the rear drying air inlet through an air supply passage, a second air passage is arranged between the front drying air inlet and the air supply passage, the second air passage clings to the outer wall of the outer cylinder and is integrated with the outer cylinder, and a switching mechanism is used for controlling the heat pump air outlet to be communicated with the front drying air inlet and / or the rear drying air inlet. The washing and drying integrated machine is simple in structure, and controllable in front and rear air inlet modes and has the characteristics of improving the clothes drying efficiency, enhancing the clothes drying effect and achieving more uniform clothes drying effect.

Description

technical field [0001] The invention relates to a washing and drying machine and a control method, in particular to a drum type washing and drying integrated machine with front and rear double drying air inlets and air inlet channels and a control method. Background technique [0002] In the drying mechanism used in the washer-dryer, the device for generating heated air adopts a heating method in which air is heated by a heater. In order to reduce energy consumption, heat pump dryers have been developed one after another, using heat pump systems to strengthen the recycling of heat. In the existing drum-type washing and drying machine, the general heating tube drying method only has the front drying air inlet, and the heat pump drying method only has the rear drying air inlet. [0003] Specifically, the following air circulation channel is provided in the existing heat pump type clothes drying device: the heated air heated by the condenser in the heat pump cycle system is se...

AI Technical Summary

Problems solved by technology

[0006] The structure of the above-mentioned washer-dryer is only provided with one drying air inlet. During the drying process, the clothes near the air inlet dry quickly, but because they are kept at a relatively high temperature for a long time, the degree of shrinkage after drying is large; stay away from The temperature of the clothes in the air inlet is low, the drying speed is slow, and it is not easy to dry, especially the clothes with a single weight are prone to uneven drying inside
