A dish washer includes: a washing tank including a sump at a bottom surface thereof; a water storage unit disposed inside or outside the washing tank to store washing water to be supplied to the washing tank; a heat pump system including a compressor that compresses and circulates refrigerant, a first heat exchanger disposed in the sump, an expansion apparatus, and a second heat exchanger disposed in the water storage unit to heat washing water for washing the dishes; and a reverse valve that changes a flow of refrigerant flowing through each of the first heat exchanger and the second heat exchanger to allow each of the first heat exchanger and the second heat exchanger to be switched from each other between a heating mode for heating the washing water and a heat recovery mode for recovering heat from washing water discharged to the outside from the washing tank.

A dish washer includes a cabinet, a tub positioned inside the cabinet, a sump provided in a lower portion of the tub, a case brake provided on a side wall of the tub connected to the sump, and a filter device positioned below the tub inside the cabinet, to selectively filter or unfilter water received from a water supply source, and to supply the filtered water or the unfiltered water to the case brake, the water passed through the case brake is collected in the sump, the case brake is located higher than the sump to prevent a backflow of the water collected in the sump to the case brake.

A cleaning device according to the present disclosure includes a first infinite belt assembly and a second infinite belt assembly disposed along a first plane and a second plane, respectively, where each plane is parallel to a longitudinal plane of the cleaning device. The second infinite belt assembly is disposed proximal to the first infinite belt assembly such that a gap is defined therebetween to receive a kitchen tool. Each of the first infinite belt assembly and the second infinite belt assembly includes bristles extending from respective outer surfaces to contact the kitchen tool. A water supply manifold of the device supplies water onto at least one of the kitchen tool, the infinite belts assemblies, and the gap. A drive unit counter rotates the first infinite belt assembly with respect to the second infinite belt assembly.

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 heat pump having a compressor, an evaporator, an expansion apparatus, and a sump condenser provided inside the sump to exchange heat with washing water inside the sump; and a controller that controls the heat pump to be driven so as to increase the temperature of the washing water inside the sump. As a result, a heating time of washing water may be shortened, thereby suppressing washing time from being prolonged.

A dish washer includes: a tub defining a washing space, a spray module disposed inside the tub and configured to spray water to the washing space, a sump configured to store water, a washing pump configured to supply the water stored in the sump to the spray module, and an air jet generator disposed below a bottom surface of the tub and configured to receive a portion of the water discharged from the washing pump to generate air bubbles in the water and discharge the water having air bubbles to the washing space. The air jet generator includes an air pulverizing pipe including a first pipe providing a cross-sectional area reducing in a water flowing direction, a second pipe providing a cross-sectional area increasing in the water flowing direction, and an air tab disposed at an upper portion of the second pipe.

Provided is a structure of a sump assembly of a dishwasher. The dishwasher includes a tub forming a washing chamber, and a sump assembly provided at a lower side of the washing chamber and configured to store washing water in the washing chamber, wherein the sump assembly includes a sump housing having a water storage chamber storing the washing water and a sidewall portion forming the water storage chamber, and a heater provided on the sidewall portion to apply heat to the washing water stored in the sump assembly. The heater includes a planar heating element, and the planar heating element provided in a cylindrical shape forms the sidewall portion.

The present disclosure relates to a dishwasher for washing the dishes and the cooking utensils by spraying washing water and steam. The dishwasher according to an embodiment of the present invention includes a tub which accommodates a washing object, a sump which is disposed in a bottom of the tub and stores washing water, a spray arm which sprays the washing water into the tub, a washing pump which sends the washing water stored in the sump to the spray arm, and a check valve which is disposed between the sump and the washing pump and opened in a direction of the washing pump from the sump.

A control box for a sprayer system is provided. The control box may include a wash flow path, a wash flow solenoid disposed in the wash flow path, a detergent supply assembly disposed in wash flow path, a rinse flow path, a rinse flow solenoid disposed in the rinse flow path, a common flow path, a flow switch disposed in the common flow path, an alternating relay, and a connection valve leading to a discharge flow path. The flow switch may be configured to provide a signal to the alternating relay. The alternating relay may be configured to control both the wash flow solenoid and the rinse flow solenoid. The connection valve may receive both the wash flow path and the rinse flow path. In another embodiment, a sprayer system including a control box and a sprayer unit is provided.

A dishwasher may include a sump configured to store water, a main arm disposed at the sump and configured to supply water from the sump, an auxiliary arm rotatably disposed at the main arm and configured to spray water, and an auxiliary arm connection member disposed at the main arm and configured to rotatably support the auxiliary arm, where the auxiliary arm may include an auxiliary flow passage configured to allow water flow through the auxiliary arm, where the main arm may include a transfer flow passage in fluid communication with the auxiliary flow passage, where the auxiliary arm connection member may include a flow tube disposed at the main arm in fluid communication with the transfer flow passage and the auxiliary flow passage.

A cleaning method includes sensing at least one trigger, where the at least one trigger is chosen from sensing a presence of a first liquid within a wash compartment of an appliance with a liquid sensor and sensing an elapsed time from activation of a faucet of the appliance with a timer. The cleaning method also includes draining the first liquid from the wash compartment of the appliance. Additionally, the cleaning method includes rinsing the wash compartment with a second liquid. The draining of the first liquid from the wash compartment of the appliance and the rinsing of the wash compartment with a second liquid are both performed prior to initiating a wash cycle of the appliance.
