The existing laundry treating apparatuses having a laundry washing function are largely classified into a pulsator type, and a drum type. However, in any of the above-mentioned clothes treatment apparatuses, when the clothes are washed, the dirt of the clothes is removed by the action of water and detergent, so that the clothes are washed.
In a drum type laundry treating apparatus, a casing is generally provided, an outer tub for containing washing water is installed therein, a drum for containing laundry is provided inside the outer tub, and a motor and a shaft for rotating the drum are provided on a rear surface of the outer tub.
In the conventional drum-type laundry treating apparatus, when a washing process is performed, the washing water flows between the drum and the outer tub in a cross manner, so that a large amount of dirt is generally remained between the outside of the drum and the inside of the outer tub. When the clothes treatment equipment without holes is used for draining, the valve body at the drainage port is driven to be opened by the rotary centrifugal force of the roller, so that the washing water in the roller flows out of the drainage port, the drained water flows into the water collecting container to be collected, and then the drained water flows out of the clothes treatment equipment through the drainage pipe connected with the water collecting container.
However, the valve body installed at the drum drain port of the above imperforate drum laundry treating apparatus generally opens or closes the drain port at the same time after the drum rotates to the same set value, which has the following problems:
in the drainage process of the clothes treatment equipment, particularly at the initial stage of a drainage procedure, the clothes treatment equipment is easy to cause the situations of high water level in a water collecting tank and the like due to over-urgent drainage, and even causes the problem that drainage water flows overflow to the outside of the clothes treatment equipment;
in addition, in the later stage of water drainage of the clothes treatment equipment, the flow speed of the drained water is reduced because the amount of residual washing water in the drum is not large, but the drum needs to be driven to rotate at a high speed in order to ensure the opening of the water drainage outlet, so that the working energy consumption of the clothes treatment equipment is increased.
In view of the above, the present invention is particularly proposed.
