A drain pump includes an impeller, a rotor configured to rotate the impeller, a stator, a first housing that defines a rotor accommodating portion, a second housing that is coupled to the first housing and that defines together with the first housing a motor accommodating space that accommodates the stator, a connector that extends from the stator and that has a contact surface configured to connect to a power source and exposed to an outside of the motor accommodating space through at least one of the first housing or the second housing, and a connector cover portion that is located at at least one of the first housing or the second housing to cover the connector and that has at least one side surface opened to expose the contact surface of the connector to the outside of the motor accommodating space.

Drain pump

A motor includes a first housing having a groove, a rotor inserted into the groove and rotatably provided outside the first housing, a second housing coupled to the first housing to form a space together with an outer circumferential surface of the groove, a stator provided in the space, a rotation shaft coupled to the rotor and extended in one direction, and a sealer coupled to the first housing to surround the rotation shaft. The sealer includes a base rotatably coupled to the rotation shaft, a gasket brought into contact with an outer circumferential surface of the rotation shaft, and a cover coupled to the base to fix the gasket to the base. The base includes a first annular protruding portion spaced apart from the rotation shaft to support the gasket, and a second annular protruding portion spaced apart from the first annular protruding portion to support the gasket.
