Abstract (en)
A dishwashing machine having liquid level control means of the type defined above, comprising a connecting conduit (19) between the bottom of a first chamber (10) and the intake duct (8) of a discharge pump (7), the volume of said connecting conduit being at least equal to that of said first chamber (10) between a predetermined liquid level (1) and a dynamic liquid level (2), the bottom of said first chamber being disposed at a higher level than a residual liquid level (3) within said tub (4) at the end of a discharge phase. In addition, said discharge conduit (19) preferably has a higher flow resistance than said intake duct (8) of said discharge pump (7), whereby soiled liquid with impurities suspended therein is prevented from entering said first chamber.
