The present disclosure relates to a dish washer having a heat pump, and the dish washer may include 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 inject washing water or air to the dishes according to a washing stroke and a drying stroke; a duct unit that defines a passage for delivering air to the injection arm; a suction fan that suctions the air and supplies the air to the injection arm; and an air heating element provided inside the duct unit to heat the air to be supplied to the injection arm, wherein the injection arm is rotatably mounted about a rotary shaft, and the plurality of nozzles rotate the injection arm by a pressure that injects the air.

A dishwasher includes: a dishwasher body including a tub that defines a washing space and a sump disposed vertically below the tub and configured to accommodate washing water; a heat pump including a compressor, a condenser, an expansion apparatus, and an evaporator; a drain storage unit connected to a drain pipe of the sump and configured to receive washing water discharged from the sump; a drain pipe open-close valve that opens and closes the drain pipe; and a controller that controls the heat pump and the drain pipe open-close valve. The evaporator is configured to exchange heat with the drain storage unit, and the controller controls the drain pipe open-close valve to open the drain pipe to move washing water of the sump to the drain storage unit when the sump is drained.

A dish treating appliance for treating dishes according to a cycle of operation can comprise a tub defining a treating chamber. The treating chamber can fluidly couple to condenser having an inlet, an outlet, and a condensing passage. The condenser can further comprise multiple ambient air inlets to mix humid air drawn from the treating chamber with ambient air within the condenser. The condenser can further integrate a water inlet with a condenser outlet, such that a water supply and condensed liquid can be provided to the treating chamber through the same opening.

The present disclosure is directed to an apparatus for rinsing and disinfecting utensils, on demand, with a controller operating the components that deliver a pre-determined volume or timed flow of water, and exposure time of sanitizer(s) to the intended objects. The spray embodiment has high performance conical spray nozzle(s) controlled by a controller that reduces water usage and that may vary depending on the viscosity of the material to be eliminated. The recirculating embodiment has a recirculating water system, with a controller operating the components that recirculate water throughout the system until the turbidity exceeds a chosen threshold, and displace with fresh water until the turbidity returns to a lower threshold. The water resumes recirculation until it again exceeds the chose turbidity threshold and the water in the system is again displaced by fresh water. Both spray and recirculating embodiments can contain multiple rinse stations.

A removable non-integrated treating chemistry dispensing cartridge assembly may emit a signal in response to a predetermined amount of treating chemistry being detected and in response to a predetermined amount of illumination being detected.

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 dishwasher comprises: (a) a washing chamber for accommodating articles to be cleaned, and comprising in its lower portion a water-collecting sump floor (12); (b) a spray arm (22) rotatably supported at the sump floor; in accordance with the present invention the dishwasher further comprises (c) a sump member (28) which comprises an insert in the sump floor (12) and which comprises an integral spray arm support (24) which rotatably supports the spray arm (22).

A household dishwasher includes a washing container receiving a dishwasher load, a spray arm for applying washing liquor and/or fresh water to the dishwasher load, a drive system for actively driving the spray arm, and an overload protection mechanism configured to move autonomously from a coupling position, in which power is transmitted between the drive system and the spray arm, into a decoupling position, in which the power transmission between the drive system and the spray arm is interrupted, when the spray arm becomes blocked

A method of cleaning soiled ware in a dishwasher, the method having the step of delivering a phosphate-free cleaning composition using a multi-dosing system, the composition comprising bleach, metal bleach catalyst and a complexing agent and wherein the complexing agent is slowly released as compared to the bleach catalyst.

The present invention relates to accessories. Specifically, the present invention relates to cleaning accessories such as jewelry that have small crevices, impressions, engravings, or other fine details that are difficult to reach and clean. Even more specifically, the present invention relates to polishing and drying the cleaned accessories by using an allotment of polishing compound and/or steam.
