ARRANGEMENT IN A DISH-WASHING MACHINE FOR REDUCING CLOGGING

摘要

In a dish-washing machine the bottom of the washing chamber (10) has an outlet opening (19) which is covered by a filter arrangement (18) comprising a tubular part (24b) of a fine sieve. The tubular part is vertically and centrally disposed in a filter housing (17) and extends through the whole housing Liquid can pass through the tubular part radially in all directions. The lower part of the filter housing (17) is connected to the suction side of a circulation pump (15) by a conduit (16) connected to the side wall of the housing. Further, a shield (26) is disposed between the tubular part (24b) of the fine sieve and the filter housing (17), the shield having a design such that the fall of pressure across the said part of the fine sieve will become essentially evenly distributed around its periphery.
