Abstract
A drain pump for a laundry treating apparatus includes a housing, an impeller, a motor, a circulation outlet, and a drain outlet. The circulation outlet and the drain outlet are defined on an outer circumferential surface of the housing, enable communication of the washing water with the housing, and protrude outward in directions tangential to the outer circumferential surface. The housing includes a rib that protrudes from an inner circumferential surface of the housing, that is located between the circulation outlet and the drain outlet, and that is configured to guide the washing water to the circulation outlet or to the drain outlet based on a direction of rotation of the impeller.
