A dishwasher includes a dishwasher cavity for treatment of items to be washed and an air outlet for blowing out air from a dishwasher cavity. The air outlet is arranged in a lower quarter of a height of the dishwasher and extends as a slotted outlet across at least two thirds of a width of the dishwasher. The air outlet includes a first air-guiding element designed for a targeted removal of air into a region in front of a front face of the dishwasher, with the first air-guiding element applying a downward component to outflowing air.

A household dishwasher includes a dishwasher cavity for processing items to be washed, a front panel attached to a front side of the household dishwasher, and an air discharge unit arranged in a lower quarter of a height of the household dishwasher and including an air outlet designed to discharge air from the dishwasher cavity and arranged in the lower quarter of the height of the household dishwasher. The air outlet extends as a slotted outlet over at least two thirds of a width of the household dishwasher. The air discharge unit is designed to be held indirectly or directly on the front panel via a retaining connection in such a way that the air discharge unit is detachable from the front panel when the front panel is dismantled.

A dishwashing appliance may include a cabinet, a tub, a pump, a spray assembly, a fluid recirculation duct, a cold water line, and a fan or a variable-flow restrictor. The tub may define a wash chamber. The pump may be configured to deliver a wash fluid to the wash chamber. The fluid recirculation duct may extend from a path inlet to a path outlet to recirculate air within the wash chamber. The path inlet may be defined in fluid communication between the wash chamber and the path outlet. The path outlet may be defined in fluid communication between the path inlet and the wash chamber downstream from the path inlet. The cold water line may define a cold water nozzle disposed within the fluid recirculation duct to provide a condensing, coldwater flow into the fluid recirculation duct between the path inlet and the path outlet.

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 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 method and apparatus for operating a dishwasher as a humidifier. The method includes, in response to an input indicating a humidifying cycle of operation, implementing the humidifying cycle of operation. The humidifying cycle of operation can include generating moisture-laden air within a treating chamber of the dishwasher and emitting the generated moisture-laden air to an exterior surrounding the dishwasher. The dishwasher implementing the humidifying cycle of operation or the dish treating cycle of operation, where the humidifying cycle and the dish treating cycle are not simultaneously implemented.

A dishwasher includes a tub defining a wash chamber, a wash rack provided within the wash chamber, an air inlet in fluid communication with the wash chamber at a first position, an air exhaust outlet in fluid communication with the wash chamber at a second position different from the first position, a first gas sensor provided in the dishwasher, and a controller configured to initiate an operation sequence. The operation sequence includes initiating a drying cycle, receiving an air-quality signal from the first gas sensor, measuring, during the drying cycle, an air-quality characteristic within the wash chamber of the dishwasher, determining the measured air-quality characteristic is below a predetermined air-quality threshold, calculating a drying time in response to determining the measured air-quality characteristic is below the predetermined air-quality threshold, and halting the drying cycle in response to an expiration of the drying time.

A household dishwasher includes a washing compartment receiving items to be washed, a control device configured to carry out a washing program selected from a number of washing programs for washing the items to be washed in the washing compartment, an optical sensor configured to acquire an optical sensor signal of the items to be washed in the washing compartment, and an evaluation unit configured to identify a drying state of the items to be washed in the washing compartment as a function of the acquired optical sensor signal.

A dishwasher appliance includes a cabinet defining a wash chamber, a sensor disposed in the wash chamber, and a controller in signal communication with the sensor. The controller is configured to adjust to one of a plurality of transfer functions in response to an output of the sensor. Each of the plurality of transfer functions is associated with a respective one of a plurality of sensor types.
