Embodiment Construction

[0026] figure 1 A first embodiment variant of a pump 10 according to the invention is shown, comprising two main components, namely a motor 12 and a hydraulic part 14 adjoining it. The hydrodynamic part 14 is surrounded by an approximately hollow cylindrical housing cover 16 in which an inlet port 18 is arranged concentrically with respect to the longitudinal axis 11 of the pump 10 . Seen from the outside, the discharge port 20 is integrally molded on the front end face of the housing cover 16 extending along a line offset relative to the axis 11 (see figure 2 ). The housing cover 16 has a connecting element 22 by means of which the pump 10 is fastened in the dishwasher. Externally on the lateral surface of the housing cover 16 is arranged a multipoint connector 24 having seven contact fins 26 immediately parallel to one another for supplying the pump 10 with power.

[0027]During operation, the pump 10 centrally draws washing liquid from the washing tub of the dishwasher ...

Abstract

The present invention relates to a pump (10, 110), particularly for dishwashers, comprising a housing made of a housing bottom (28, 128), a housing cover (16, 116), and a heating device (30, 130, 36,136) disposed in between the bottom and cover for heating a washing fluid, the device forming a ring-shaped side wall of the housing, further comprising an impeller (40, 140) arranged in the housing,an intake connection (18, 118) arranged axially in the housing cover (16, 116) relative to the axis of rotation of the impeller (40, 140), and a pressure connection (20, 120), wherein the pressure connection (20, 120) is arranged in the housing cover (16, 116).

Description

technical field [0001] The invention relates to a pump, in particular for a dishwasher, comprising a housing comprising a housing base, a housing cover, and a housing between the housing base and the housing cover for A heating device for heating the washing liquid, the device forms the annular side wall of the housing; the pump also includes an impeller, the impeller is arranged in the housing; an input port, the input port is at the axially disposed within the housing cover; and a discharge port. Background technique [0002] A pump of this type for dishwashers is known from German patent publication DE 20107363 U1. A disadvantage of the described pump is the vertical arrangement of the outlet port relative to the axially arranged inlet port. The discharge port protrudes beyond the substantially cylindrical shape of the pump, resulting in a greater length of the pump in the radial direction. The pump requires more installation space and reduces the space available for t...
