Abstract

A drain pump (and/or recirculating pump) for a clothes washing machine which has no dynamic leak paths exterior to the washing machine outer bowl (1, 20). The pump (19) is contained within a housing (3/9, 25) which is either formed integrally with the outer bowl or connects directly within an aperture provided in the bottom of the bowl using a single static seal. The pump inlet is directly exposed to the interior of the outer bowl. The pump motor (5, 64) has a rotor (4, 29) mounted within the pump housing with the interconnected pump impeller (8, 27) to obviate the need for a dynamic water seal for the rotor drive shaft (7,31). The rotor can run wet. The stator (6, 35) is mounted outside of the housing such that the housing wall (14, 28) lies in the motor air gap. The motor is preferably a brushless dc motor.
