Abstract

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.

Claims20

Dependent claims

A drain pump, comprising:

an impeller;
a rotor comprising a rotary shaft coupled to the impeller, the rotor being configured to provide rotational force to the impeller;
a stator located at an outer circumferential surface of the rotor and configured to rotate the rotor;
a first housing that defines a rotor accommodating portion that accommodates the rotor, the rotor being configured to rotate in the rotor accommodating portion;
a second housing coupled to the first housing, the second housing, together with the first housing, defining a motor accommodating space that accommodates the stator;
a connector that extends from the stator, the connector comprising 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, the connector cover portion having at least one side surface opened to expose the contact surface of the connector to the outside of the motor accommodating space.

5 more elements

A drain pump, comprising:

an impeller;
a motor coupled to the impeller and configured to provide rotational force to the impeller;
a motor housing configured to accommodate the motor;
a connector having a first end electrically connected to the motor and a second end exposed to an outside of the motor housing, the connector comprising a contact surface configured to connect to an external power source and spaced apart from the impeller in an axial direction;
and
a connector cover portion that is located at the motor housing and that covers the connector,
wherein the connector cover portion comprises:
a first axial side surface that defines a cover opening opened in a direction opposite to the impeller,
a second axial side surface opposite to the first axial side surface,
a first circumferential side surface and a second circumferential side surface that are spaced apart from each other in a circumferential direction and that are each extend in the axial direction from the first axial side surface to the second axial side surface, and
a radial side surface that defines an outer surface of the connector cover portion and that connects the second axial side surface, the first circumferential side surface, and the second circumferential side surface.
