Benefits of technology

The present invention is about a drain pump that can easily release air and a washing machine with it. The drain pump has an air outlet port located at the top of its compartment, which is connected to a drain hose to remove the air. This makes it convenient to discharge air from the pump, and helps to improve its performance.

Problems solved by technology

If the air is introduced into an inside the pump, the performance of the impeller installed in the drain pump compartment may be degraded, and thus a drain fault may occur or an abnormal noise may be generated.
