Abstract
An example vent assembly for a dishwasher having a tub at least partially defining a treating chamber, and an exhaust vent, includes a condenser having an outlet, and an inlet in fluid communication with the treating chamber, an ambient air cooling duct in thermal communication with the condenser, and having an outlet in fluid communication with the exhaust vent, a venturi having an inlet in communication with the outlet of the condenser, and an outlet in communication with the cooling duct, and a fan for flowing ambient air through the cooling duct, past the venturi, and out the exhaust vent.
Claims20
A vent assembly for a dishwasher having a tub at least partially defining a treating chamber, and an exhaust vent, the vent assembly comprising:
- a condenser having an outlet, and an inlet in fluid communication with the treating chamber of the dishwasher;
- an ambient air cooling duct in thermal communication with the condenser, and having an outlet in fluid communication with the exhaust vent;
- a venturi having an inlet in communication with the outlet of the condenser, and an outlet in communication with the cooling duct;
- and
- a fan for flowing ambient air through the cooling duct, past the venturi, and out the exhaust vent.
A method of venting exhaust air from a dishwasher, comprising:
- circulating air through a condenser to condense moisture from the air;
- operating a fan to pass ambient air through a cooling duct to thermally conduct heat from the condenser to the ambient air to condense the moisture;
- drawing the air from the condenser into the cooling duct through a venturi;
- and
- venting a mixture of the ambient air and the air from the condenser through a vent to exhaust air from the dishwasher.
