Dishwasher, a door assembly for the dishwasher, and an associated method for drying dishware
A dishwasher, a door assembly for the dishwasher and a method of drying the dishware in the dishwasher are provided. The dishwasher may include a tub portion adapted to hold dishware. The dishwasher may also include a duct having an inlet proximate to the top of the tub portion. The duct may be configured to receive warm air and vaporized water from within the tub portion. The dishwasher may further include a single blower configured to direct the warm air and vaporized water into the duct during a drying cycle. The blower may be configured to operate in a cyclic manner. In various embodiments, the blower may be configured to operate in a reverse direction for at least a portion of the drying cycle.
1. A dishwasher configured to perform at least one washing program, the at least one washing program comprising a drying cycle, the dishwasher comprising:
a tub defining an opening and an interior;
a door attached to the tub and configured to selectively permit access to the interior of the tub;
at least one washing element configured to wash dishware disposed within the tub;
a duct positioned within the door, the duct having an inlet that is in fluid communication with the interior of the tub and an outlet that is in fluid communication with an external environment, the duct extending from the inlet to the outlet, wherein the duct is configured to receive warm air and vaporized water from within the tub;
a blower configured to direct the warm air and vaporized water into the duct during at least a portion of the drying cycle of the at least one washing program; and
a control unit configured to operate the blower in a selectively activated manner during the drying cycle, wherein operating the blower in the selectively activated manner comprises:
activating the blower in a direction wherein the warm air and vaporized water are directed into the inlet and deactivating the blower, wherein the activating and deactivating the blower occur a plurality of times during the drying cycle;
at least one time during the drying cycle, alternating between activating the blower a) in the direction where the warm air and vaporized water are directed into the inlet, and b) in a reversed direction of operation wherein ambient air from the external environment is drawn into the duct via the outlet to interact with the vaporized water within the duct to accelerate the condensation of the vaporized water.
2. The dishwasher of claim 1 , wherein the duct is configured to provide a path for the warm air and vaporized water to travel from the inlet toward the outlet.
3. The dishwasher of claim 1 , wherein the control unit is further configured to cause the alternating of the blower to occur a plurality of times during the drying cycle.
4. The dishwasher of claim 1 , wherein the duct at least partially defines a tortuous path, wherein the tortuous path is configured to facilitate condensation of vaporized water from warm air as the warm air and vaporized water are directed through the duct.
