A dishwasher includes a dishwasher interior for washing items to be washed with washing liquor. Arranged at a lower end of the dishwasher interior is a pump sump for collecting the washing liquor, and a sensor is arranged in the pump sump for outputting a sensor signal as a function of a presence of washing liquor at the sensor. A control apparatus configured to carry out a washing program selected from a number of washing programs is designed to determine a malfunction of a component of a hydraulic assembly as a function of the sensor signal and of a current operating state of the dishwasher.

This invention relates in general to an industrial cleaning apparatus. The cleaning apparatus has a cleaning tank which has a generally rectangular configuration having two opposing major sides, two opposing minor sides and an opening. A lid is pivotally connected to one of the major sides and adapted to allow access to the cleaning tank when opened and to close the opening of the cleaning tank in use. A horizontally disposed support frame supports the kitchen articles within the cleaning tank. A heating system is disposed within the cleaning tank and heats the fluid therein. A lift assembly raises and lowers the support frame by a remotely operated control system. In use, when the lift assembly is remotely controlled to raise and lower the support frame a corresponding vertical motion of the support frame opens and closes the lid.

Disclosed is a dishwasher ejecting wash water containing microbubbles. The dishwasher according to an embodiment includes a tub accommodating dishes therein, a plurality of wash arms spraying wash water into the tub, a bubble nozzle ejecting wash water containing microbubbles to the bottom of the tub, a sump disposed below the bottom of the tub and collecting wash water therein, a wash pump pumping wash water collected in the sump, a channel-switching unit supplying wash water pumped by the wash pump to at least one of the plurality of wash arms, and a bubble module generating microbubbles in wash water pumped by the wash pump and supplying the wash water containing microbubbles to the bubble nozzle, and a controller operates the wash pump and controls the channel-switching unit and the bubble module to spray wash water through at least one of the plurality of wash arms and simultaneously to eject wash water through the bubble nozzle.

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 dishwashing appliance, as provided herein, may include a cabinet, a tub, a pump, a spray assembly, a fluid recirculation duct, and a cold water line. The tub may be housed within the cabinet and define a wash chamber. The fluid recirculation duct may extend from a path inlet to a path outlet to recirculate air within the wash chamber. The path inlet may be defined in fluid communication between the wash chamber and the path outlet. The path outlet may be defined in fluid communication between the path inlet and the wash chamber downstream from the path inlet. The cold water line may extend through the fluid recirculation duct. The cold water line may define a cold water nozzle that is disposed within the fluid recirculation duct to provide a condensing, cold-water flow into the fluid recirculation duct between the path inlet and the path outlet.

Ergonomic Intelligent Dishwasher comprising of closed-loop carousel system, tableware storage holder and a Wash-Pod. Individual tableware is inserted through an opening where the tableware attaches to a closed-loop, speed-adjustable carousel-system that moves the individual tableware, in a queue-fashion, through one or more wash cycle as the attached-tableware travels towards the tableware separation-mechanism. Tableware separation-mechanism is activated or deactivated for each individual tableware in the said queue on the carousel based on user-define setting or an internal quality-control process, thus, when deactivated, attached tableware on the carousel continues to travel through additional said cleaning cycle in the loop until such time when carousel-tableware separation-mechanism is activated. Once the tableware is discharged and separated from the carousel, the tableware is directed to one or more tableware storage holder. As part of the same unit, Wash-Pod is a housing within the unit with closeable lid for washing kitchenware items based on user parameters.

A dishwashing appliance, as provided herein, may include a cabinet, a tub, a water tank, a wet air duct, a dry air duct, a water supply conduit, a diverter valve, and a diverted branch. The tub may be housed within the cabinet and may define a wash chamber. The water tank may be mounted within the cabinet outside of the wash chamber. The wet air duct may extend from the wash chamber to the water tank. The dry air duct may extend from the water tank to the wash chamber. The water supply conduit may extend to the wash chamber. The diverter valve may be disposed along the water supply conduit upstream from the wash chamber. The diverted branch may extend from the diverter valve to the water tank to selectively guide water from the water supply conduit to the water tank.

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 dishwashing appliance includes a tub defining a wash chamber therein for receipt of articles for washing, a heating element, a sump positioned at a bottom of the wash chamber for receiving fluid from the wash chamber, a drain pump in communication with the sump, and a temperature sensor. Methods of operating the dishwashing appliance may include filling the sump with a liquid and heating the liquid by activating the heating element. Such methods also may include measuring a temperature of a liquid in the sump with the temperature sensor and comparing the measured temperature of the liquid to a minimum drain temperature threshold. Such methods may include draining the liquid from the sump after the measured temperature is equal to or greater than the minimum drain temperature threshold, such as immediately after heating the liquid.

A heater assembly includes a heater having a pair of heating terminals, an integrated module, the heater is mounted on a first side of the integrated module and the heating terminals extend from a second side of the integrated module opposite to the first side, a ground terminal mounted on the second side of the integrated module and grounding the integrated module, and a connecting housing having a receiving portion. The ground terminal is arranged in a row with the heating terminals. The heating terminals and the ground terminal are inserted into the receiving portion through a bottom wall of the receiving portion.
