A dishwashing appliance includes a tub defining a wash chamber. An inlet is defined in the tub and provides air flow into the wash chamber. An air handler selectively urges air through the inlet in one of a first direction and a second direction different from the first direction. The air flows from the inlet and through the wash chamber of the tub along a first defined path when the air handler urges air through the inlet in the first direction, and the air flows from the inlet and through the wash chamber of the tub along a second defined path when the air handler urges air through the inlet in the second direction.

A domestic dishwasher includes a wash container which has a loading opening. The loading opening of the wash container can be closed by a door. A suction apparatus is provided to suction steam and/or air, in particular moisture-laden air, escaping from the loading opening. The suction apparatus has at least one inlet window located outside a wet chamber of the wash container.

A water-using household appliance, in particular a household dishwashing machine, includes a wall which is made from a metal material, and a device which is made from a plastic material and fixedly connected to the wall by a laser weld.

A dish washer includes: a washing tank including a sump at a bottom surface thereof; a water storage unit disposed inside or outside the washing tank to store washing water to be supplied to the washing tank; a heat pump system including a compressor that compresses and circulates refrigerant, a first heat exchanger disposed in the sump, an expansion apparatus, and a second heat exchanger disposed in the water storage unit to heat washing water for washing the dishes; and a reverse valve that changes a flow of refrigerant flowing through each of the first heat exchanger and the second heat exchanger to allow each of the first heat exchanger and the second heat exchanger to be switched from each other between a heating mode for heating the washing water and a heat recovery mode for recovering heat from washing water discharged to the outside from the washing tank.

A dish washer includes: a washing tank having an accommodation space for storing dishes therein; an injection arm disposed inside the washing tank, and provided with a plurality of nozzles to selectively inject washing water and air to the dishes according to a washing stroke and a drying stroke; a duct unit that defines a passage for delivering the air to the injection arm; a suction fan provided inside the duct unit to suction the air and supply the air to the injection arm; and an air heating element that heats the air to be supplied to the injection arm.

The present disclosure relates to a dishwasher having a heat pump, including a dishwasher body provided with a tub configured with a washing space therein and a sump provided at a bottom of the tub to temporarily accommodate washing water; a heat pump having a compressor, an evaporator, an expansion apparatus, and a condenser provided on an inner bottom surface of the tub to exchange heat with washing water inside the tub; and a controller that controls the heat pump to be driven to increase the temperature of the washing water inside the tub. As a result, the heating time of washing water may be shortened.

A dish washer includes a washing tank having an accommodation space for storing dishes therein; an injection arm disposed inside the washing tank, and provided with a plurality of nozzles to selectively inject washing water and air to the dishes according to a washing operation and a drying operation; a duct unit that defines a passage of the air to be supplied to the injection arm; a suction fan provided inside the duct unit to suction the air and supply the air to the injection arm; and an air heating element that heats the air to be supplied to the injection arm, wherein the injection arm includes a partition wall that partitions a washing water passage and an air passage therein.

A dishwasher may include a tub at least partially defining a treating chamber, an airflow conduit, and a blower assembly fluidly coupled to the airflow conduit. The blower assembly may include a first impeller effecting a flow of ambient air to the treating chamber and a second impeller effecting a flow of mixed air from the treating chamber exhausting the mixed air from the treating chamber. Additionally, at least one of the first and second impellers may effect a flow of ambient air that bypasses the tub and combines with the mixed air before being exhausted from the dishwasher.

A method and appliance utilize one or more sprayers that are coupled to both a liquid supply and an air supply through a common hydraulic circuit such that both liquid and pressurized air can be supplied to the one or more sprayers. A common motor may operate both an air pump and/or a water pump of the appliance. The air pump and/or water pump may supply fluid to one or more sprayers and/or other apparatuses within the appliance.

A dishwashing appliance includes a tub defining a wash chamber. The tub includes an inlet and an outlet. The dishwashing appliance also includes a drying system in fluid communication with the wash chamber. The drying system includes a heat pipe heat exchanger having a condenser section and an evaporator section. The evaporator section is downstream of the outlet. The condenser section is downstream of the evaporator section and upstream of the inlet. A thermoelectric assembly is in thermal communication with the heat pipe heat exchanger.
