Combination water inlet, vent stack, blower and blower housing assembly

Abstract

A water inlet, vent stack, blower and blower housing combined assembly for use in an automatic dishwasher. The combined assembly comprises a water inlet nozzle having an inlet end connectable to a valve-controlled water source, and a discharge end. A vent stack is provided in the form of an open top chamber having sides, ends and a bottom, with a lateral conduit extending from the lower portion of one side to be sealingly engaged about an opening in the dishwasher vat. A blower housing is located beneath the vent stack, and a duct is located along side the vent stack. The lower end of the duct is connected to the blower housing and the upper end thereof is connected to and encloses the open upper end of the vent stack. The water inlet nozzle extends through an opening in the upper end of the duct with its discharge end extending into the vent stack. A motor and fan are mounted on a motor plate, in turn mounted on a blower plate. The blower plate is affixed to the blower housing. The combined assembly introduces wash and rinse water into the dishwasher vat, serves as a vent for the vat, and circulates air therein, requiring a single opening in the vat wall for these purposes. The water inlet nozzle and vent stack subassembly can be used alone to introduce wash and rinse water into the dishwasher vat and to serve as a vent for the vat.
