Benefits of technology

The present invention aims to provide a laundry treating machine that can reduce the noise and vibration caused by the water discharge pump during a spinning cycle. This control method helps to minimize the impact of the pump, making it more efficient and effective in removing water from clothes.

Problems solved by technology

The water discharge pump has to be actuated in the spinning cycle, because noise and vibration are likely to occur if the water held in the tub after separated from the laundry collides against the drum rotating at a high rotation number.
However, the amount of the water separated from the laundry during the spinning cycle gets decreased as time passes.
Thus, unless controlling the rotation number of the impeller provided in the water discharge pump, noise and vibration might occur in the water discharge pump disadvantageously.
