The present invention is an apparatus and a green and economical method for washing and sanitizing cookware including pots, pans and containers suitable for all types of cookware, wherein the washing and sanitization method is a two stage process involving utilization of cold water jet for washing of utensils and heating water for sanitization of the cookware without the use of detergents or chemicals.

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.

Disclosed is a blade-heating heat pump cover and a heat pump. By providing the mounting slot on the cover body in a direction of protruding from the second surface to the first surface, and providing the heating element in the mounting slot, the application makes the heating element be provided on the cover body without contacting the liquid medium, and the liquid medium be heated through the cover body, thus avoiding the occurrence of leakage caused by corrosion of the heating element by the liquid medium; by providing the heating wire in the heating element, and bending and providing the heating wire in the first end of the heating element for heating, and one part of the heating wire being located on the second end of the heating element being connected to the external circuit, the application is easy to install, assembly and maintain.

A dish washing device includes an inner compartment and a water collection cup arranged at a bottom part of the inner compartment, a wash pump and a heating apparatus are arranged on the water collection cup and/or a first water supply pipeline. The wash pump is used for pumping washing water inside the water collection cup to the inner compartment via the first water supply pipeline, and the heating apparatus is used for selectively heating the washing water. The heating apparatus includes a thermoelectric cooler used for heating the washing water. In comparison to heating washing water using an electric heater, thermo- electric cooler may save a large amount of power, thereby reducing the power consumption of the dishwashing device, and facilitating energy conservation and eco-friendliness.

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 has a housing (10) with a wash chamber (20) and a top wall (204) with a non-planar surface (214;214″) facing downwardly into the wash chamber, the surface having portions (216,218; 226,228) facing downwardly and facing in different horizontal directions (H1,H2; HX,HY,HP,HQ). Nozzles (402) mounted within the wash chamber spray a liquid upwardly within the wash chamber. The surface portions redistribute the upwardly-sprayed water in horizontal directions to provide a more uniform washing action. A portable dishwasher may have a fresh water reservoir (422) and a used water reservoir (430) mounted in the housing beneath the wash chamber. The used water reservoir may be removably mounted in the housing so that the user can remove used wash water by removing the used water reservoir. The portable dishwasher can be used at a location remote from a sink.

A waste storage device and an intelligent management system are provided. The waste storage device includes: a casing, a control module disposed in the casing, a microphone module disposed on an outer surface of the casing, and a moving module electrically connected to the control module. The microphone module is electrically connected to the control module. When the microphone module receives a first audio signal, the microphone module transmits the first audio signal to the control module, the control module analyzes an audio sending direction of the first audio signal, and the control module provides a driving signal to the moving module according to the first audio signal to drive the waste storage device to move in the audio sending direction.

A dishwasher thermometer captures temperature data of temperature sensed within a dishwasher during a wash cycle. The dishwasher thermometer includes a wireless communication interface that transmits the captured temperature data to one or more of a server and a monitor device. When the captured temperature data indicates that the wash cycle did not achieve defined temperature threshold(s), an alert is generated at the server and/or the monitor device indicating that the wash cycle did not meet appropriate washing conditions. In embodiments, the temperature data may be accessible to a third party for certification of the dishwasher wash cycle.

A dish washing machine including a housing having an interior wash space for washing dishes. The housing has a liquid inlet for adding a liquid to the dish washing machine. At least one rotating spray nozzle sprays the liquid onto dishes positioned within the interior wash space. The machine further includes a heating tank for heating the liquid which is supplied to the at least one rotating spray nozzle for spraying onto the dishes in the interior wash space. Two heat exchange systems are within the housing. The two heat exchange systems transfer heat from the liquid heated by the heating tank to the liquid added to the dish washing machine from the liquid inlet. A first one of the two heat exchange systems passes heat from water in the wash tank or the interior wash space to water in the first one of the two heat exchange systems.

A compact dishwasher for cleaning a few eating utensils includes a wash container disposed on a base. A clean water tank is disposed on the base and in fluid communication with the wash container for supplying clean water to the wash container. A wastewater tank is disposed on the base and in fluid communication with the wash container for receiving wastewater from the wash container. A housing body encompasses the wash container, the clean water tank, and the wastewater tank. The dishwasher can further comprise a first pump for facilitating pressurized discharge of clean water in the wash container and a second pump disposed for facilitating drainage of wastewater from the wash container into the wastewater tank. A heating coil can be employed to provide hot water to the wash container. The dishwasher can further include a cleaning basket insertable through the top of the dishwasher.
