A method of controlling a dishwasher includes washing an object accommodated inside a tub by spraying water and detergent onto the object, rinsing the object by spraying water onto the object, drying the object by removing moisture adhered to the object, detecting an amount of a rinsing agent, comparing the detected amount of the rinsing agent to a predetermined amount, based on the comparison, determining whether the detected amount of the rinsing agent is less than the predetermined amount, and increasing at least one of a temperature of water to be supplied in the rinsing or a drying time in the drying based on determining that the detected amount of the rinsing agent is less than the predetermined amount.

A dishwasher includes: a tub including a washing room; and a dryer installed on one side of the tub, the dryer including: a first housing coupled with the tub and communicating with the washing room; a second housing coupled with an other side of the first housing, and forming a flow path together with the first housing so that inside air of the washing room circulates back to the washing room by passing through the flow path; a heater accommodated inside the first housing and the second housing to heat the air passing through the flow path; and a switch module positioned upstream of the heater, configured to detect an inside temperature of the flow path to turn on or off the heater based on the detected inside temperature, and fixed between the first housing and the second housing by coupling of the first housing with the second housing.

A washing machine such as a dishwashing machine, preferably of the drawer-style or table-top style, or a laundry washing machine, the washing machine having at least one low-height wash liquid conduit connecting the outlet of a sump region of a washing tub to a wash pump. A cover plate is provided for covering a section of the washing tub base and the at least one low-height conduit is formed between the base of the washing tub and the cover plate by a combination thereof. The surface of a heating unit forms a surface of the low-height conduit and the sump is provided with multiple outlets.

A dishwasher appliance includes a caloric heat pump system that is configured for heating and cooling a wash chamber of a tub. A field generator is positioned such that caloric material stages are moved in and out of a field of the field generator during operation of the caloric heat pump system. A pump circulates a heat transfer fluid between a first heat exchanger, a second heat exchanger and the caloric material stages.

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 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 for treating dishes according to a cycle of operation includes a tub at least partially defining a treating chamber, a liquid supply conduit, and a rotatable sprayer that is rotatable about a rotation axis and has an inlet and multiple nozzles collectively forming an outlet. The dishwasher further includes a hydraulic drive fluidly coupling the liquid supply conduit to the rotatable sprayer. The hydraulic drive is mechanically coupled to the rotatable sprayer.
