A dishwasher is provided in which tableware is capable of being washed with washing water of a high pressure by preventing the pressure of the washing water from dropping. The dishwasher includes a main body in which a washing tub is formed, a sump provided in the main body and storing washing water, a plurality of injection nozzles to inject the washing water into the washing tub, a plurality of flow passages respectively connected to the plurality of injection nozzles, and a distribution apparatus configured to selectively open and close the plurality of flow passages and communicate with the plurality of flow passages, respectively, and including rotary member having a plurality of independent connection passages and a case in which the rotary member is accommodated.

The present disclosure relates to a dishmachine that includes at least two tanks and methods of using the tanks to isolate, substantially isolate, or incrementally isolate different chemistries from each other during a cycle. The disclosed dishmachine design and method allows for the use of two different, and potentially incompatible, reactive, or offsetting chemistries to be used in the same dishmachine cycle.

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 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.

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.

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.

Provided is a dishwasher having an improved structure capable of selecting whether to spray wash water. The dishwasher includes a washing tub, a basket provided in the washing tub to accommodate dishware, a duct provided in the washing tub to be supplied with wash water, a sub-duct mounted on the basket to guide the wash water, a connection pipe connected to the sub-duct, and a spray nozzle coupled to the connection pipe to be rotatable from a first position where the connection pipe is open and a second position where the connection pipe is closed.

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 counter system (10) for transferring at least partially unpackaged foodstuffs, wherein the counter system (10) has a first region (11) assigned to the counter staff and a second region (12) segregated therefrom and assigned to the customer. The counter system (10) has a dishwasher (1) for cleaning items of washware (2). The dishwasher (1) has at least one treatment zone (3) and at least one conveyor apparatus (6) for conveying the items of washware (2) to be cleaned from an introduction region (4) of the dishwasher (1) through the treatment zone (3) of the dishwasher (1) to a removal region (5) of the dishwasher (1), wherein the introduction region (4) of the dishwasher (1) is accessible from the second region (12) of the counter system (10) and the removal region (5) of the dishwasher (1) is accessible from the first region (11) of the counter system (10).

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.
