Detailed Description

In order to more clearly illustrate the above objects, features and advantages of the present application, a detailed description of the present application is provided in this section in conjunction with the accompanying drawings. The present application is capable of embodiments in addition to those described herein, and its several details are capable of modifications in various obvious respects, all without departing from the spirit of the present application, and it is therefore intended that the present application not be limited to the particular embodiments disclosed in this section. The protection scope of the present application shall be subject to the claims.

As shown in fig. 1 to 22, the present application provides a washing machine including a washing tub 100 for receiving objects to be washed and washing water; a pressing portion for pressing an object to be cleaned (for example, laundry) in cleaning tub 100; a pressurizing unit for supplying air to the pressing unit to pressurize the pressing unit; a suction unit for sucking washing water from an object to be washed; a pressurizing path connecting the pressing portion and the discharge port of the pressurizing portion; a suction path connecting the cleaning tank 100 and a suction port of the suction unit; a gas-liquid separator 500 for separating water and gas; and a control unit for controlling the washing process, the rinsing process and the dewatering process to perform the washing operation.

The control unit may be configured to supply air to the pressing portion in the washing step to perform pressure washing for pressing the object to be washed, and to perform suction dehydration for sucking the washing water from the object to be washed in the dehydration step. The wash bowl 100 may be connected with a water inlet valve for injecting water into the wash bowl 100.

The washing machine further includes an air path integration structure integrating at least a portion of the pressurization path and the suction path.

Referring to fig. 3 and 4, the air path integration structure includes a housing 1, a channel is formed inside the housing 1, and the housing 1 itself defines a wall of the channel. Alternatively, the housing 1 may include a first housing 101 and a second housing 102, and the first housing 101 and the second housing 102 may be plastic members integrally formed by molds, respectively. The first housing 101 and the second housing 102 may be sealingly connected by, for example, a sealing ring, and the first housing 101 and the second housing 102 may each define a wall of a portion of the passage.

It will be appreciated that the above-described passages can be conveniently formed by connecting the first and

The channel formed by connecting a plurality of pipelines through various joints needs to clear the connection relation of each pipeline to ensure correct installation in assembly production or maintenance, so the assembly difficulty is high, the requirement on operators is high, the number of the joints is large, the occupied space is large, and the leakage risk is high.

TABLE 2

(Pre-pressurization)

When the first actuator 11 and the second actuator 12 are in the first state and the third actuator 13 and the fourth actuator 14 are in the second state, the pump 400 pre-pressurizes and inflates the first pressing portion 200 and the second pressing portion 300.

(Wash, first bladder pressurized)

When the first actuator 11 and the third actuator 13 are in the first state and the second actuator 12 and the fourth actuator 14 are in the second state, the pump 400 sucks air from the second pressing portion 300 to inflate the first pressing portion 200, and the first pressing portion 200 presses and washes the objects to be washed in the washing tub 100.
