ABSTRACT:
An air flow control for a dishwasher is provided in which a spray pump motor has a blower wheel mounted thereon to provide cooling to the spray pump motor. The motor is positioned within an enclosed housing having an air inlet and two air outlets. One of the air outlets is provided with an air passage leading to an exit opening in a sump of the dishwasher. The sump communicates with the wash cavity of the dishwasher through a conduit and, during the wash and rinse portions of a washing cycle receives and retains a predetermined level of wash liquid. The air passage exit opening is positioned at an elevation below the predetermined wash liquid level in the sump so that during the wash and rinse portion of the wash cycle, air will be prevented from moving through the air passage into the wash cavity. However, once the wash liquid level drops below the predetermined level, air will be forced through the wash cavity.
