In addition, the system may include a deflector that deflects the water from the backwash nozzle to the fine filter.

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 stroke and a drying stroke; a duct unit that defines a passage for delivering the air 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.

A spraying apparatus and a dish-washing machine. The spraying apparatus comprises: a spraying pipe, a water injection nozzle being provided on the spraying pipe; a drive mechanism, the drive mechanism comprising a driving gear and a driven gear engaging with the driving gear, and the driven gear being connected to the spraying pipe to drive the spraying pipe to rotate; a driving mechanism, the driving mechanism being connected to the driving gear to drive the driving gear to rotate. The rotation of the spraying pipe in the spraying apparatus is stable and reliable, and control precision of a spraying region is high.

A system and method for cleaning a dish, comprising: illuminating said dish with a light source; capturing an image of said dish with a camera; inspecting said image to determine if said dish is clean; and estimating locations of dirty regions on said dish; spraying a fluid with a first nozzle on said dish with a predetermined spray distribution, wherein said first nozzle can reorient or relocate to spray said fluid on any region of said dish visible in said image; and spraying a fluid with a second nozzle on said dish with a spray distribution having a smaller coverage than that of said first nozzle, wherein said second nozzle is relocated or reoriented such that the fluid reaches said dirty regions at said locations on said dish; whereby dirty regions of said dish are targeted for a fast and efficient cleaning of said dish.

A dishwasher includes: a tub defining a space that is configured to receive a target object to be washed, a sump disposed below the tub and configured to receive water, a pump connected to the sump and configured to move the water in the sump to the space of the tub, an air jet generator configured to receive a part of the water discharged from the pump and configured generate air bubbles in the water, and a control valve configured to control a flow of the water to the air jet generator.

The present invention is a washing apparatus for induction suitable cookware and also involves the method of washing. The apparatus can be incorporated in restaurants, operated manually or incorporated in automatic cooking systems. The apparatus comprises of an induction heating unit, a replaceable water nozzle, a sink, an induction element, a ceramic glass, a pump, an electric motor, a controller, a manual HMI and a vision system.

The present application discloses a water spraying pipe and a cleaning apparatus. The water spaying pipe includes a pipe body having a water inlet end and defining a water spraying hole in a pipe wall thereof; and a water spraying groove defined in the water spraying pipe at a position corresponding to the water spraying hole. The water spraying hole is in communication with the water spraying groove, and a diameter of the water spraying hole is greater than a width of the water spraying groove. The present application effectively improves the cleaning efficiency of the water spraying pipe.

The present disclosure relates to a dishmachine that includes one or more features directed to water, energy or material savings. The disclosed dishmachines are still capable of meeting the soil demands of the articles to be cleaned.

A dishwashing appliance, as provided herein, may include a cabinet, a tub, a pump, a spray assembly, a first fluid path, and a second fluid path. The first fluid path may extend from a first path inlet to a first path outlet to recirculate air within a wash chamber. The first path inlet may be defined in fluid communication between the wash chamber and the first path outlet. The second fluid path may extend from a second path inlet to a second path outlet to direct ambient air to the wash chamber. The second path inlet may be defined in fluid communication between an ambient environment surrounding the dishwashing appliance and the second path outlet. The second path outlet may be defined in fluid communication between the second path inlet and the wash chamber downstream from the second path inlet.
