A dishwasher for treating dishes according to at least one cycle of operation and having a tub at least partially defining a treating chamber and defining an access opening, a sprayer providing a spray of liquid into the treating chamber, a liquid recirculation system defining a recirculation flow path for recirculating the sprayed liquid from the treating chamber to the sprayer, and an air supply system having a conduit configured to function as an overflow conduit.

A dishwashing appliance may include a cabinet, a tub, a pump, a spray assembly, a fluid recirculation duct, a cold water loop, a heat exchanger, and a tub fan. The fluid recirculation duct may extend from a path inlet to a path outlet to recirculate air within a wash chamber. The cold water loop may define a cold water nozzle disposed within the fluid recirculation duct to provide a condensing, cold-water flow into the fluid recirculation duct between the path inlet and the path outlet. The heat exchanger may be mounted to the cold water loop outside of the fluid recirculation duct to cool water within the cold water loop. The tub fan may be configured to selectively motivate an airflow from the path inlet to the path outlet.

A dishwasher and method for making and/or using the same utilize one or more walking tubular spray elements that may be used to effectively increase the spray coverage area of the tubular spray elements through rotation and/or movement of the walking tubular spray elements in directions other than about the longitudinal axes thereof.

A method controls a dishwasher including a tub configured to receive objects to be washed, a drying device configured to receive wet air from the tub and to discharge the wet air to an outside of the dishwasher, and a dry air supplier including a heating part and being configured to supply heated air to the tub. The method includes preheating the drying device by introducing dry air from the outside to the drying device before a first preset time from a start point of a drying operation, performing the drying operation at the start point, wherein the wet air is discharged from the tub during the drying operation, and cooling the dry air supplier by stopping operation of the heating part before a second preset time from an end time point of the drying operation.

The present invention relates to a dishwasher, a method for controlling the operation of the dishwasher, and a program therefor. To this end, a dishwasher according to one embodiment of the present invention may comprise: a tub having a washing space therein and open on the front; a door which opens and closes the open front of the tub; a drying air supply unit including a blowing motor, a blowing fan, a heater, and a temperature sensor; and a processor controlling the operation of the dishwasher. The processor can control the ON/OFF of the heater so that the temperature of the heater is maintained within a first threshold range when the time during which the dishwasher enters and operates in a door open drying process is less than a predetermined time. Accordingly, the present invention can efficiently dry dishes by controlling the operation of the heater so that the temperature of the heater is maintained within a certain range.

A household dishwasher includes a dishwasher cavity for processing items to be washed, and an air outlet designed to blow out dishwasher interior air of the dishwasher cavity. The air outlet is arranged in a lower quarter of a height of the household dishwasher and extends as a slot outlet over at least half of a width of the household dishwasher.

A dishwasher includes a dishwasher cavity for treatment of items to be washed, and an air outlet for blowing out air from the dishwasher cavity. The air outlet is arranged in a lower quarter of a height of the dishwasher and extends as a slotted outlet over at least two thirds of a width of the dishwasher. A connection located on a rear face of the air outlet introduces humid air into the air outlet and is designed to supply the introduced air to an air distributor for separating the supplied air into differently oriented sub-flows.

A dishwasher includes a tub having a top wall and opposing sidewalls that at least partially define a washing chamber. A housing coupled to the top wall of the tub. A motor disposed in the housing. A lead screw operably coupled to the motor, the lead screw extends between the opposing sidewalls of the tub. An air knife assembly is operably coupled to the lead screw. The air knife assembly is operable between a stowed state and a deployed state. The motor drives rotation of the lead screw to move the air knife assembly, the air knife assembly including, an air knife defining an air inlet and an air outlet, and a blower coupled to the air knife. The blower is configured to direct air through the air outlet of the air knife to generate an air curtain when the air knife assembly is in the deployed state.

A dishwasher includes a tub having a top wall extending between opposing side walls. The tub defines a washing chamber. A dishrack operable between a stowed state within the washing chamber and a deployed state extending at least partially out of the washing chamber. An air drying system is coupled to the tub and includes a housing coupled to the top wall of the tub. The housing extends into the washing chamber proximate the dishrack and defines an air inlet. An air knife coupled to the housing and extending along a width of the washing chamber proximate to the top wall of the tub. The air knife defines a slit. A blower operably coupled to the air knife is configured to draw air through the air inlet and direct the air through the slit of the air knife to generate an air curtain across the width of the washing chamber.

Glass washing apparatus and related methods clean a glass and suppress formation of water spots. A glass washing apparatus includes a housing, an access door, a glass holder, a first side wash nozzle, a second side wash nozzle, a third side wash nozzle, an interior wash nozzle, a drying air outlet, a clean water tank, a dirty water tank, a wash water pump, a heater/blower unit, a control panel, and a control unit. The control unit receives a start signal from the control panel, controls transmission of power to the wash water heater, controls transmission of power to the wash water pump to supply heated clean water to the first side wash nozzle, the second side wash nozzle, the third side wash nozzle, and the interior wash nozzle; and controls transmission of power to the heater/blower unit to supply a flow of heated air to dry the glass.
