In another aspect, the sump is provided with multiple outlets. In another aspect, a cover plate is provided for covering a section of a washing tub base and the at least one low-height conduit is formed between the base of the washing tub and the cover plate by a combination thereof. In another aspect, a pump cap component is located in the washing tub, the pump cap component having upper and lower spaced walls and at least one connecting wall between the upper and lower spaced walls, the connecting wall(s) arranged so as to form a closed shape when viewed from above, the closed shape including a wash pump housing volume for an impeller of the wash pump.

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 dishwasher includes: a tub that defines an washing chamber; spray nozzles configured to spray washing water into the washing chamber; a sump configured to store washing water; a steam nozzle configured to supply steam to the washing chamber; a washing pump housing coupled to the sump and connected to the spray nozzles or the steam nozzle; a heater configured to heat washing water in the washing pump housing; a washing motor configured to rotate an impeller; a washing water outflow pipe defining an outflow path protruding outward from one side of the washing pump housing; a steam discharge pipe that extends from a discharge port defined at a circumferential surface of the washing water outflow pipe; and a first protrusion disposed in an upper portion of the outflow path and disposed downstream of the discharge port in a flow direction of the washing water.

A conveyor type ware washing machine uses a heat pump to reduce exhaust heat and to heat incoming water. A modulating valve is used to control incoming water flow through a heat exchanger of the heat pump. Processing circuitry automatically dynamically adjusts the modulating valve between a plurality of open states based on the sensed refrigerant head pressure of the heat pump, so that the refrigerant head pressure is maintained in a predefined range. The ware washing machine is efficient, and reduces the amount of heat exhausted to ambient. Related methods are also disclosed.

Provided is a structure of a sump assembly of a dishwasher. The dishwasher includes a tub forming a washing chamber, and a sump assembly provided at a lower side of the washing chamber and configured to store washing water in the washing chamber, wherein the sump assembly includes a sump housing having a water storage chamber storing the washing water and a sidewall portion forming the water storage chamber, and a heater provided on the sidewall portion to apply heat to the washing water stored in the sump assembly. The heater includes a planar heating element, and the planar heating element provided in a cylindrical shape forms the sidewall portion.

A steam generator for generating steam by boiling water, or other hot water heating device, in either case such as for use in a steam cooker or warewasher, includes a tank structure providing a heating chamber for holding water, and at least one heating element associated with the tank structure for heating water. The tank structure includes a main body wall having a U-shaped cross-sectional profile formed by opposed first and second side wall portions of the heating chamber and a curved bottom wall portion of the heating chamber, wherein the curved bottom wall portion is monolithic with the first and second side wall portions, wherein the main body wall is sheet metal material that has been curved.

A dishwasher (100) for washing dirty articles comprising: a rotating rack (1) configured to rotate counter-clockwise at a user-defined speed of 1 round per minute or round per minute; a spray system (104) configured to dispense a jet stream of high speed water using a plurality of nozzles (106a-106n) from the bottom as well as top of the dirty articles placed on the rotating rack (1); a washing chamber (1b) that may be designed to enable washing of the dirty articles placed upon the rotating rack (1) using the spray system (104), wherein the washing chamber (1b) uses recirculating water; and a rinsing chamber (1c) that may be designed to rinse the washed articles with clean water supplied directly from a house water source; wherein a partition wall (29) between the washing chamber (1b) and the rinsing chamber (1c) prevents splash of water used in the respective chamber.

A heating system component for a heating system for heating a fluid medium is provided. The heating system component includes: a carrier unit comprising a wet side, wherein said wet side corresponds to a surface of said carrier unit configured to be in contact with said fluid medium; and a heating unit.
