A household dishwasher includes: a washing water spray nozzle module disposed on an area of inner surfaces of a washing chamber and spraying washing water, which is supplied from a water supply tube, into the washing chamber; a steam generation module disposed in the washing chamber and supplying steam into the washing chamber using the washing water supplied from the washing water spray nozzle module; an induction module disposed on an outer surface of the washing chamber and heating the washing water supplied in the washing chamber; an ultrasonic vibration module disposed on an outer surface of the washing chamber and applying ultrasonic vibration to the washing water in the washing chamber to perform ultrasonic washing; and a controller disposed in a body and controlling operational relationships of internal components in response to washing order signals from a user.

A free-standing Energy Recovery System enables sanitary recovery of thermal energy with heat transfer from hot waste effluent to incoming domestic water. The source of the effluent may, for example, be conventional commercial ware-washing, clothes washing equipment, pasteurization and other industrial processes.

A dosing unit (100) for automatically dosing a dosing amount (122) of a solid detergent provided by a storage cartridge (110) for storing a bulk (112) of the solid detergent, for use in an automatic dosing system (20) of a water-bearing household appliance (1), wherein the storage cartridge (110) comprises a reversibly deformable container (114) with an outlet (116), wherein by deforming the container (114) according to a predefined pattern in time detergent of the bulk (112) is transported towards the outlet (116), and a dosing device (120) is attached to the storage cartridge (110) on the outlet (116) for separating the dosing amount (122) from the bulk (112) and releasing the separated dosing amount (122).

The present inventive concept relates to a method for optimizing water usage in a device utilizing water for a group of cleaning procedures, wherein the device comprises a sensor arrangement (518) and a data processing device, wherein the method comprises the steps of: determining a first substance content (400a) of first cleaning phase water from a first cleaning phase of the cleaning procedure (428) using the sensor arrangement (518); in the data processing device, receiving data comprising a target substance content interval requirement (844) of at least one of a plurality of cleaning phases (314); in the data processing device, comparing the first substance content to the target substance content interval requirement (844); and forming cleaning phase water to be used in the at least one of the plurality of cleaning phases (314) by transferring the first cleaning phase water to the at least one of the plurality of cleaning phases (314) based on the comparison.

A method of washing induction cookware having a cookware content, using induction heating and a water jet, and comprising a washing process having the steps of: heating the cookware during a washing cycle; washing the cookware in the washing cycle with a cold-water jet; drying the cookware after the washing cycle; heat sanitization of the cookware; and steam sanitization of the cookware, whereby the washing process is analyzed by a vision system, the washing process is controlled and adjusted by a controller having parameters varying between each of the cookware content; whereby the parameters are derived from an interfaced cooking apparatus and from a manual input and whereby the vision system serves to regulate a water pressure, a water flow, a heating temperature, and time durations between each of the cookware content, with each of the cookware content having a cooking base, a food contact surface, recipe ingredients cooked, a cooking temperature, and a cooking duration.

A dishwasher and method for making and/or using the same utilize one or more walking tubular spray elements that may be used to effectively increase the spray coverage area of the tubular spray elements through rotation and/or movement of the walking tubular spray elements in directions other than about the longitudinal axes thereof.

A household dishwasher includes: a washing water spray nozzle module disposed on an area of inner surfaces of a washing chamber and spraying washing water, which is supplied from a water supply tube, into the washing chamber; a steam generation module disposed in the washing chamber and supplying steam into the washing chamber using the washing water supplied from the washing water spray nozzle module; an induction module disposed on an outer surface of the washing chamber and heating the washing water supplied in the washing chamber; an ultrasonic vibration module disposed on an outer surface of the washing chamber and applying ultrasonic vibration to the washing water in the washing chamber to perform ultrasonic washing; and a controller disposed in a body and controlling operational relationships of internal components in response to washing order signals from a user.

A dishwasher appliance includes a sump, a water supply valve for providing a flow of water into the sump, and a circulation pump that circulates water that is collected in the sump to one or more spray arm assemblies. A pressure sensor is operably coupled to the sump for monitoring sump pressure and wash fluid level. A controller regulates the water supply valve to provide the flow of water into the sump and monitors the sump pressure during the fill process. The controller further determines that the circulation pump is primed when the rate of increase of the sump pressure exceeds the predetermined threshold rate and stops further filling of the sump.

A method of draining a wash tank of a warewash machine involves: (a) turning off, or maintaining off, both a booster tank heater and a wash tank heater of the machine; (b) simultaneously operating a rinse pump, operating a drain pump and opening a booster fill valve of the machine so that all of the following take place at the same time: (b1) fresh water is delivered through a heat exchanger to the booster tank; (b2) fresh water is delivered by the rinse pump from the booster tank to a rinse spray system and falls down into the wash tank; and (b3) liquid from the wash tank is delivered by the drain pump to a drain flow path and through the heat exchanger to exchange heat with the fresh water delivered through the heat exchanger.

Appliances configured to detect leaks and methods of detecting leaks are provided. The appliance includes a grounded chassis. The appliance also includes a first levelling leg electrically coupled to the chassis and a second levelling leg electrically isolated from the chassis. The appliance also includes a controller in in operative communication with the second levelling leg and the chassis. The controller is configured for, and related methods include, monitoring electrical continuity between the second levelling leg and the chassis and detecting water on the base surface in response to electrical continuity between the second levelling leg and the chassis.
