A method includes supplying, using a water supply coupled to a tub of a dishwasher, water into the tub, wherein the tub includes a sump and a sprayer; circulating, using a circulation circuit coupled to the sump and the sprayer, the water from a sump to the sprayer; storing, using a water tank coupled to the circulation circuit, the circulated water from the circulation circuit on completion of a first phase; drawing heat, using a supply side of a thermoelectric module system coupled to the circulation circuit and the water tank, from the stored water in the water tank from the first phase; and outputting, using an output side of the thermoelectric module system, heat to the circulated water in the circulation circuit for a second phase.

A dishwasher comprises a tub; a sump in which water supplied to the tub is accommodated; and a water tank disposed at one side of the tub. The water tank comprises a water storage part; a water supply channel that is connected to the sump and supplies water to the water storage part; an inlet which is provided at the top of the water storage part and through which water supplied via the water supply channel is introduced into the water storage part; an excessive supply water return channel which communicates at a first end thereof with the inlet and communicates at a second end thereof with the tub; and a floating cap which is provided under the inlet in the water storage part to selectively block the inlet according to the amount of water accommodated in the water storage part, wherein when the water storage is full of water, the floating cap blocks the inlet to disconnect the water storage part from the excessive supply water return channel.

Provided are a method performed by an appliance for washing and rinsing goods, where some of the goods loaded into the appliance are sensitive to process water temperature changes, and an appliance performing the method. The method may include receiving via a user interface, an instruction that an appliance, during execution of a general-type washing program, should take into account that goods sensitive to temperature changes are loaded into the appliance, measuring a temperature value in a washing compartment of the appliance upon executing a draining process, and supplying fresh water to the washing compartment of the appliance. The method may include measuring, when the fresh water has been supplied, whether the process water being accommodated in a sump of the appliance is at a target temperature value or not and if not adjusting the temperature of the process water in the sump to attain the target temperature value.

The present invention relates to a dishwasher. The dishwasher according to the present invention includes a tub for providing a washing space, a rack for accommodating dishes in the tub, a spray nozzle for spraying wash water toward the dishes accommodated in the rack, a sump for supplying the wash water to the spray nozzle, a pump for pumping the wash water stored in the sump to the spray nozzle, a supply pipe connecting the sump and the spray nozzle, and an air jet generator disposed in a supply flow path formed by the supply pipe to suck outside air to the wash water flowing along the supply pipe and crush the air to thereby form air bubbles.

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 spray arm provided inside the washing space to spray washing water; a circulation pump that pumps the washing water of the sump; a washing water guide that guides the washing water pumped by the circulation pump to the spray arm; a heat pump provided with a compressor, an evaporator, an expansion apparatus, and a condenser provided to exchange heat in contact with the washing water of the washing water guide; and a controller that controls the heat pump to increase the temperature of the washing water of the washing water guide. As a result, it may be possible to suppress heat loss from being generated while heating washing water.

The present invention relates to a dishwasher. The dishwasher of the present invention comprises: a tub; a sump which is disposed under the tub and in which washing water is stored; a spray arm which is disposed within the tub and sprays the tub with washing water; a pump which supplies the spray arm with washing water stored in the sump; a washing water flow pipe which supplies the spray arm with washing water discharged from the pump; and a bubble generator which is disposed in the spray arm or connection pipe and has a Venturi-tube shape to generate bubbles in washing water flowing therethrough.

Disclosed herein is a dishwasher. The dishwasher includes a main body, a tub provided inside the main body, a basket provided inside the tub to store items, an injection assembly configured to spray water to wash the item in the basket, and a duct including a first body configured to supply water to the injection assembly and provided to extend along a first direction, and a second body to which water flows and provided to extend from the first body to along second direction. The duct is formed by coupling of a first housing provided to form at least a portion of the first body and the second body, and a second housing provided to form another portion of the first body and the second body.
