Inside the body, the water storage tank is supported by a plurality of support bodies; inside the water storage tank, a washing tub is provided for washing and dehydrating after the laundry is placed; and a pulsator is disposed inside the washing tub.

At the rear of the top cover, there is a detergent box rack capable of inserting or removing the detergent box, a water supply pipe connected to the detergent box frame, and an inlet valve connected to the water supply pipe, and the water inlet end of the inlet valve A filter is provided inside.

An upper cover is provided on the central portion of the top cover to enable the laundry to be placed into or removed from the washing tub; and a control panel is disposed on the upper portion behind the top cover. Control members such as a controller that controls various operations of the washing machine are provided on the bottom surface of the control panel.

In the washing machine structured as described above, after the user opens the upper cover and puts the laundry into the washing tub, and inputs the required washing operation through the input button provided on the control panel, the inlet valve is opened, and the washing water flows in. Go to the washing tub until the water level is set.

Thereafter, the motor is driven, and the driving force of the motor is appropriately reduced and transmitted to the pulsator or the washing tub, and the washing operation is performed; when the washing operation is completed, the washing operation is performed several times; after the flushing operation is completed, the washing tub is finished. Dewatering at the same time as high-speed rotation; thus completing a series of washing processes.

However, due to the current poor water quality in many areas, such as rural areas and some foreign countries, after several uses, the impurities in the water will block the filter and cause the water to enter slowly or not, and the washing machine can not be used normally. The structure of the water valve is limited. The current inlet pipe and inlet valve are basically standard interface design. The filter at the inlet can not be made too large due to space limitation, resulting in less filtered water, which is easy to block and enter.
