As shown in fig. 1 and 2, the present invention provides an air intake system of a washing machine, comprising an impeller 1, a housing 2 and an air guide duct 3. Wherein, impeller 1 is driven by motor 100 to rotate, and housing 2 covers and locates on impeller 1, is provided with air intake 21 and air outlet 22 on the housing 2, can inhale the housing 2 with external air from air intake 21 when impeller 1 rotates to with the air in the housing 2 from air outlet 22 discharge, the air inlet end 31 of guide duct 3 communicates with air outlet 22, and air outlet end 32 communicates with washing machine's inner tube 200.
In the invention, the impeller 1 which is linked with the motor 100 is arranged to generate air flow, the housing 2 and the air guide pipe 3 are arranged in cooperation with the impeller, and the air flow is guided into the inner cylinder 200 after being pressurized, so that air can be continuously blown into the inner cylinder 200 during the dewatering operation of the washing machine, and the air flow flows through or passes through clothes, so that more moisture on the clothes is separated, and the water content of the clothes after the dewatering operation is effectively reduced.
Alternatively, the air outlet 32 is connected to the gasket 300 of the washing machine, and communicates with the inner tub 200 from the gasket 300. The above arrangement can prevent foam from remaining on the laundry in the window gasket 300, the inner tub 200, and the inner tub 200 by striking the laundry in the window gasket 300, the inner tub 200, and the inner tub 200 with the airflow.
Alternatively, the motor 100 is a power motor for driving the drum of the washing machine to rotate, and the housing 2 is disposed in the washing machine and covers the outer side of the motor 100. The above arrangement makes the impeller 1 perform heat dissipation and temperature reduction on the motor 100, and can seal the noise generated by the motor 100 during operation in the housing 2, and transmit the noise to the sealed inner cylinder 200 through the air guide pipe 3, thereby effectively reducing the noise generated by the motor 100 during operation of the washing machine.
Specifically, the impeller 1 is connected to the rotating shaft 101 of the motor 100, and when the motor 100 works, the rotating speed of the impeller 1 is equal to the rotating speed of the rotating shaft 101, so that the wind speed is lower during normal washing and higher during dehydration, and the rotating speed of the impeller 1 is more adaptive to the working state of the washing machine.

Through the setting of speed change mechanism, make the rotational speed of impeller 1 and the rotational speed of the axis of rotation 101 of motor 100 different to can reduce impeller 1's size specification, improve impeller 1's application scope.
Alternatively, the speed change mechanism may be a gear mechanism including a first gear connected to the rotation shaft 101 of the motor 100 and a second gear connected to the impeller 1, the first gear and the second gear being engaged, and the radius of the first gear being larger than that of the second gear. Besides the arrangement, the speed change mechanism can also be a planetary gear mechanism or a belt pulley mechanism, specifically aiming at realizing the purpose of improving rotation, and the details are not repeated here. The above arrangement allows the impeller 1 to rotate more rapidly than the rotation shaft 101 of the motor 100, and can produce a larger air volume, thereby effectively improving the effects of dehydration, foam removal and noise reduction.
Alternatively, the transmission mechanism is a gearbox or torque converter, which is a conventional arrangement in the art, and the specific structure and operation principle are not described here in detail. Specifically, the speed change mechanism is controlled by the control device of the washing machine, and in the running process of the washing machine, the control device of the washing machine can control the rotation speed of the impeller 1 according to the needs so as to correspondingly set different rotation speeds according to the quantity and the materials of clothes to be washed, thereby being capable of saving more energy and being more efficient.
