Abstract

A spray arm assembly for a dishwasher, comprising a spray arm (12; 74) comprising a plurality of spraying nozzles (40, 42, 60; 76), and support means (16; 56; 78) comprising a mounting element (18; 50; 80) for mounting the support means within the dishwasher and a support member (20; 54; 82) on which the spray arm (12; 74) rests during periods of non-use. The spray arm assembly is characterized in that it further comprises - first supplemental outlet means (24, 48, 58; 92) to direct, during periods of use, liquid to between the support member (20; 54; 82) and the spray arm (12; 74) so as to form a liquid layer between the support member and the spray arm, on which liquid layer the spray arm floats during rotation, and - second supplemental outlet means (28; 86) to direct, during periods of use, liquid to between the spray arm (12, 74) and a guiding surface (34) provided at the support means, so as to stabilize rotation of the spray arm.

Description

technical field [0001] The invention relates to a spray arm assembly for a dishwasher, comprising a spray arm having a plurality of spray nozzles, and support means for rotatably arranging the spray arm, wherein the support means comprises means for supporting A mounting element where the device is mounted in the dishwasher and a support member on which the spray arm rests during non-operational periods. Background technique [0002] Conventional dishwashers, such as domestic dishwashers, have a tank defining a wash chamber with a front opening.
