Abstract

The shaft axis of a detergent-solution pump in a washing machine is pivoted about a vertical such that, as seen in the forward direction, it forms an acute angle α with a perpendicular center plane running from the front surface to the rear wall of the machine housing. The drain connector for the drain hose from the tub to the pump is oriented on the tub casing with an angular offset in the preferred spinning direction of rotation in relation to the vertical plane running through the drum axis. These measures give rise to better accessibility to the pump chamber and to improved pumping capacity, in particular for foam/water mixtures. The pump-out operation is shortened, and the overall height of the pump-out system can be reduced.
