Embodiment Construction

[0015] Although this description will refer to many different features of dishwashers, one useful and advantageous feature is a filter assembly that includes a nozzle for spraying liquid into the filter bowl. The nozzles improve filter assembly function by flushing away large food particles with a stream of water to allow a continuous flow of fluid through the filter. Another advantageous feature is a sump assembly that includes a drain volute with a regulated vent for priming the drain pump. This adjustable vent allows the sump pump to operate more efficiently. Yet another advantageous feature is that the insertion sleeve for the filter assembly forms a displacement body to raise the liquid level in the cistern. Many dishwashers run on low water volumes to conserve water and reduce energy levels. Thus, the displacement body can provide more efficient fluid filtration by causing a higher water level in the filter assembly to allow fluid to flow into the filter.

Abstract

A dishwasher includes a tub at least partially defining a treating chamber with an access opening, a sump fluidly coupled to the treating chamber, at least one sprayer emitting liquid into the treating chamber, a pump, a conduit fluidly coupling the sump to the pump and the pump to the at least one sprayer, thereby defining a recirculation circuit through which the liquid sprayed into the treatingchamber collects in the sump and is pumped back to the at least one sprayer, a filter assembly provided in the sump and having a filter through which at least a portion of the liquid passes, and an insert sleeve at least partially located within the filter assembly.

Description

technical field [0001] The present invention relates to a dishwasher. Background technique [0002] Modern automatic dishwashers used in typical households include a tub defining a treatment chamber and a spray system for recirculating liquid through the tub to remove soil from dishes and utensils. The inner tank includes at its lowest point a reservoir that collects liquid supplied to the treatment chamber for washing dishes. A sump unit including a pump assembly may be provided for recirculating and draining liquid from the sump. The pump assembly must be below the sump so that the wash liquid in the sump can be gravity fed into the pump assembly. Liquid can be drained into the sump and recirculated back to the liner via a recirculation loop. The recirculation loop may include a filter assembly to filter particulates from the liquid before it enters the liner. A dirty or clogged filter assembly can prevent the filter assembly from effectively filtering liquids. Conte...
