Problems solved by technology

[0006] Therefore, when the valve body of the drain valve is opened by such washing water, the valve body of the drain valve acts on the downward pressure, so the drain valve closes early with the flow of the washing water, and there is a problem that remains in the washing water tank after the drain valve closes the drain port. The water level (dead water level
