The present disclosure relates to a pump for transmitting washing water and generating steam and a dishwasher including the pump. The pump includes a housing; a washing water inlet pipe coupled to the housing to receive washing water; a washing water outlet pipe coupled to the housing to discharge the washing water; an impeller disposed in the housing to discharge the washing water from the washing water inlet pipe to the washing water outlet pipe; a heater coupled to the housing to heat the washing water in the housing and generate steam; a steam discharge pipe to discharge the steam generated by the heater; and a selector valve coupled to the steam discharge pipe to block the discharge of the washing water and allow the steam to be discharged, thereby preventing the discharge of washing water through the steam discharge pipe.

A dishwasher (1) includes a treatment zone (3) and a conveyor apparatus (4) for transporting washware items (2) from a placement area (5) through the treatment zone (3) to a removal area (6). A washing and/or rinsing system has at least one washing and/or rinsing pump (9) and washing and/or rinsing nozzles. The dishwasher (1) is spatially partitioned into an over table area (7), which, when the dishwasher (1) is used as intended, is positioned above a counter level (13), and an under table area (8), which, when the dishwasher (1) is used as intended, is positioned below the counter level (13), wherein the placement area (5), the removal area (6) and the treatment zone (3) are respectively part of the over table area (7), and wherein at least the washing and/or rinsing pump (9) of the washing and/or rinsing system is part of the under table area (8).

A pump sends washing water and generates steam in order to wash the dishes or the cooking utensils, and a dishwasher including the same. The pump includes a housing, an impeller disposed inside the housing and configured to flow washing water, and a heater coupled to a lower side of the housing and configured to generate steam by heating the washing water in the housing. The housing includes a pump lower portion configured to receive the washing water based on rotation of the impeller, and a pump upper portion configured to discharge the washing water based on rotation of the impeller and to discharge the steam generated by the heater.

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 reusable food or beverage container system and method of operation automates tracking, returning, washing, and outputting of reusable food or beverage containers. A reusable food or beverage container has an identification device associated therewith. The reusable food or beverage container is used to supply a food or beverage to a customer and associated with a customer identifier. When the customer is done using the reusable food or beverage container, it is returned to a receptacle of the system, and automatically transported to a washing subsystem where it is washed, sanitized, and dried, and then output to a stack or other organized storage structure of container.

Experimental color data obtained from a plurality of cleaning process verification coupons is used to determine optimized cleaning process parameters in an automated cleaning machine. Color data may also be obtained from cleaning process verification coupon(s) to verify the efficacy of a real-world cleaning processes in an automated cleaning machine and/or to obtain one or more suggested corrective action(s) in the event the cleaning process yields an unsatisfactory cleaning result. Based on the optimized cleaning process parameters, an automated cleaning machine may automatically adjust one or more cleaning process parameters to correct for non-optimized parameters sensed during execution of a cleaning process to help prevent an unsatisfactory cleaning result.

A dishwasher and method utilize one or more sprayers to generate steam within a wash tub of a dishwasher by directing one or more sprays of fluid onto a heating element disposed in the wash tub of the dishwasher.

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.
