Clothes washing and drying machine

Abstract

The invention discloses a clothes washing and drying machine which comprises a machine body, a machine door, a water bucket, a rotary drum, a heat pump component, a heating gas pipeline, a moisture absorption gas pipeline and a valve, wherein a holding space is defined in the machine body; the machine door is arranged on the machine body in a pivot and rotatable manner; the water bucket is arranged in the holding space; an air suction port and an air exhaust port are formed in the rear wall and the side wall of the water bucket respectively; the rotary drum is rotationally arranged in the water holding drum; an accommodating space communicated with the air suction port and the air exhaust pipe is arranged in the rotary drum; the heat pump component is arranged in the holding space; a first end and a second end of the heating gas pipeline are communicated with the air suction port and the heat pump component respectively; a first end and a second end of the moisture absorption gas pipeline are communicated with the air exhaust port and the heat pump component respectively; and the valve is in a normally-closed state under the action of gravity and rotates in a direction towards the first end of the heating gas pipeline under the action of an air flow of hot air so as to be in an opened state. According to the clothes washing and drying machine, foam can be prevented from entering the heating gas pipeline.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a washing and drying machine. Background technique [0002] At present, most of the washing and drying machines on the market are not equipped with a structure to prevent foam from pouring into the air duct, resulting in a large amount of foam generated during the laundry process pouring into the air duct, corroding the electrical appliances and metal components in the air duct, and causing serious damage. Security risks. [0003] Although some heat pump washing and drying machines are equipped with a structure to prevent foam, most of them use micro-motors to control the valve switch, which is not only costly but also unreliable. Contents of the invention [0004] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, an object of the present invention is to provide a washing and drying machine with simple and reliable...
