Abstract
A water inlet assembly for mounting adjacent an opening provided in a tub of an automatic dishwasher wherein the tub defines a cavity having a volume for washing dishes. The water inlet assembly includes a housing forming a venting chamber and having an outlet opening mounted in sealed relationship about the opening provided in the tub. The venting chamber has a vent opening which may be located above the outlet opening. The housing further includes an inlet nozzle for receiving wash liquid and a conduit for guiding liquid from the inlet nozzle to the venting chamber from which wash liquid can flow through the outlet opening into the tub. A water trap is formed into the housing and is located along the conduit. The conduit has a siphon opening located upstream of the water trap. A pressure actuated valve is positioned to block the passage of air from the tub cavity through the venting chamber and out the vent opening in a closed state and to allow the passage of air from the tub cavity through the venting chamber and out the vent opening in an open state. The pressure actuated valve moves from the closed to the open state in response to an excess of air pressure in the tub cavity.
