ABSTRACT:
In a dish-washing machine the bottom of the washing chamber has an outlet opening which is covered by a filter arrangement comprising a tubular part of a fine sieve. The tubular part is vertically and centrally disposed in a filter housing and extends through the whole housing. Liquid can pass through the tubular part radially in all directions. The lower part of the filter housing is connected to the suction side of a circulation pump by a conduit connected to the side wall of the housing. Further, a shield is disposed between the tubular part of the fine sieve and the filter housing, the shield having a construction and arrangement whereby the pressure drop across the tubular part of the fine sieve will become essentially evenly distributed around its periphery.
