A pump includes a housing, a water inlet pipe coupled to the housing and configured to receive washing water, a water outlet pipe coupled to the housing and configured to discharge washing water, an impeller located in the housing and configured to cause washing water to be transferred from the water inlet pipe to the water outlet pipe, a heater that is coupled to the housing, that is configured to heat washing water in the housing, and that is configured to generate steam based on heating washing water, and a steam discharge pipe coupled to the water outlet pipe and configured to discharge steam generated by the heater.

A drain box having a housing, a splash containment therein with a lower portion within a housing drain aperture, and a discharge conduit having a lower portion positioned within the splash containment in position above the drain aperture and extending upward through splash containment aperture, and an upper portion extending upward through a housing upper aperture and terminating above the housing upper portion for connection to an appliance discharge conduit. The conduit being attached to the housing to prevent a lower discharge conduit end from moving downward toward the drain aperture to less than a predetermined minimum distance above the housing drain aperture.

A dishwasher may include: a tub having a washing chamber formed therein, the tub including an opened bottom and an opening flange are formed in the opened bottom; a distribution device to distribute washing water sprayed into the washing chamber; a sump housing couplable to the opening flange of the tub, the sump housing including a distribution chamber to accomodate at least a portion of the distribution device; a support plate disposed on the opening flange of the tub, the support plate including a plate opening corresponding to the distribution chamber; and a distribution cover to be insertable into the plate opening and to be rotated, and coupled to the support plate while pressing the support plate, to cover an upper portion of the distribution chamber.

A dishwasher comprising a tub; a drain port including a port body, a first port coupling portion extending along an edge of an outer circumferential surface of the port body, and a second port coupling portion extending along an edge of an outer circumferential surface of the port body, the second port coupling portion having a length longer than a length of the first port coupling portion; and a drain pump, to be coupleable to and decouplable from the drain port. The drain pump includes: a first pump coupling portion to allow the drain pump to couple to and decouple from the first port coupling portion; a second pump coupling portion to allow the drain pump to couple to and decouple from the second port coupling portion; and an interfering rib to interfere with the second port coupling portion to thereby prevent the first pump coupling portion from being coupled to the second port coupling portion or prevent the second pump coupling portion from being coupled to the first port coupling portion.

A dishwasher includes a tub, a drain housing to drain wash water in the tub, a drain pump detachably coupled to the drain housing, the drain pump configured to pump the wash water, a drain port formed on one side of the drain housing, the drain port comprising a port body to allow the wash water pumped by the drain pump to flow, and a locking portion formed on an outer surface of the port body, and a drain hose to drain wash water discharged from the drain port to an outside of the dishwasher, the drain hose comprising a hose body and a drain connector at one end of the hose body and connectable to the drain port. The drain connector includes a locking hook to be locked to the locking portion in response to inserting the drain connector into the port body.

A heat pump dishwasher includes a chassis and a heat pump system. A liquid collecting groove is provided at an upper side of the chassis. The heat pump system includes an evaporator and a compressor, both the evaporator and the compressor are installed at the chassis, and the compressor is installed at the liquid collecting groove. Condensed water may be collected, and condensation water may be avoided in the liquid collecting groove and may reduce the corrosion of the liquid collecting groove and may reduce interruptions to the operation of electrical components.

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.

A condensate drain pipe apparatus for providing drainage for a condensate pump includes a main drain having a main top end, a main bottom end, and a main sidewall extending therebetween. A dishwasher drain has a main end coupled to the main sidewall of the main drain, a dishwasher end, and a dishwasher sidewall extending therebetween. The dishwasher drain is in fluid communication with the main drain. The dishwasher drain extends perpendicularly from the main drain and the dishwasher end is configured to be coupled to a dishwasher drainage tube. A condensate drain has a drain end coupled to the dishwasher sidewall of the dishwasher drain, a hose end, and a condensate sidewall extending therebetween. The condensate drain is in fluid communication with the dishwasher drain and the hose end is configured to be coupled to a condensate pump hose.

A dishwasher appliance equipped with flood protection features that proactively attempt to prevent, stop, and/or mitigate flood events is provided. The dishwasher appliance may also include features for determining the cause of the flood event. Moreover, methods for flood protection of the dishwasher appliance are also provided.

An apparatus for reducing emulsions in kitchen effluent discharging to a FOG removal apparatus includes a pre-rinse sink, a tank positioned below the pre-rinse sink to receive effluent from the pre-rinse sink, an outlet from the tank and leading to a pipe, a valve in the outlet having an open position and a closed position, a dishwasher having a drain connected to the pipe, and a control for the valve to be in its closed position when the dishwasher is discharging to the pipe.
