A beverage container washing system may be used for rapid washing and/or sanitizing of beverage containers, e.g., for use in a retail environment to wash and/or sanitize customer-provided beverage containers prior to filling the beverage containers with purchased beverages, among other applications. Separate entrance and exit openings may be provided in some instances to minimize employee interaction with unwashed customer beverage containers. A spray assembly may be used to spray wash fluid heated to a sanitizing temperature onto beverage containers and an ultraviolet sanitizing assembly may be used to emit ultraviolet light toward beverage containers. The spray assembly may also include a tank with first and second chambers and a cross-over with an inverted conduit fluidly coupling the first and second chambers.

A cleaning device, in particular a dishwasher, includes: a cleaning container having a cleaning chamber and accommodating cleaning material to be cleaned; a heat pump device which has an evaporator arranged inside a heat storage medium tank; and an intermediate storage positioned above the heat storage medium tank, the intermediate storage receiving liquid heat storage medium displaced from the heat storage medium tank.

A dishwasher appliance includes a caloric heat pump system that is configured for heating and cooling a wash chamber of a tub. A field generator is positioned such that caloric material stages are moved in and out of a field of the field generator during operation of the caloric heat pump system. A pump circulates a heat transfer fluid between a first heat exchanger, a second heat exchanger and the caloric material stages.

A warewash machine includes a chamber for receiving wares, the chamber having at least one wash zone. A refrigerant circuit includes multiple condensers including a condenser to deliver refrigerant heat to incoming water that is being delivered into the machine. A primary flow path for incoming water passes through a waste heat recovery unit and a secondary flow path for incoming water bypasses the waste heat recovery unit. A valve is provided for selectively controlling whether refrigerant flows along the primary flow path or the secondary flow path based upon a subcooled condition of refrigerant in the refrigerant circuit.

A warewash machine includes a chamber for receiving wares, the chamber having at least one wash zone. A refrigerant medium circuit includes a first condenser and a second condenser, the first condenser located upstream of the second condenser in the refrigerant circuit. The refrigerant medium circuit includes a first flow path through the first condenser and a second flow path in bypass of the first condenser, and a valve for selectively controlling whether at least some refrigerant medium flows along the first flow path or the second flow path.

A warewash machine includes a chamber for receiving wares, the chamber having at least one wash zone. A refrigerant medium circuit includes a first heat exchanger arranged to deliver refrigerant medium heat to a first fluid and a second heat exchanger arranged to provide a heat exchange relationship between the refrigerant medium and a second fluid, the first heat exchanger located upstream of the second heat exchanger in the refrigerant medium circuit. A bypass arrangement for causing at least some refrigerant medium to selectively bypass at least one of the first condenser or the second condenser based upon subcooled refrigerant medium condition.

A drying system includes a tub having a plurality of walls. The tub also defines a wet chamber. The drying system also includes a heat pipe heat exchanger integrally joined to one of the plurality of walls of the tub. The drying system may be provided in a dishwashing appliance. A method of making a dishwashing appliance includes positioning a pipe within a mold and forming a portion of the dishwashing appliance over the pipe in the mold.

An auxiliary gray water supply device captures used wash water from a commercial warewashing machine for supply to a pre-rinse station without substantial modification of the commercial warewashing machine. The captured wash water and treatment agent are delivered to a pre-rinse station for pre-rinsing of dishes that will be washed within the commercial warewashing machine.

A washer includes: a supply-water storage section configured to store supply water; a wastewater storage section configured to temporarily store wastewater and a wastewater heat recovery device including a water supply channel through which the supply water is supplied to the supply-water storage section and a drain channel through which the wastewater is drained from the wastewater storage section, and configured to exchange heat between the wastewater flowing in the drain channel and the supply water flowing in the water supply channel. the wastewater heat recovery device is disposed below the washing chamber, and is provided in a machine chamber in which a pump configured to deliver the supply water from the supply-water storage section to the washing chamber is disposed, and the drain channel is connected to a drain hole of the wastewater storage section.

This disclosure proposes a cleaning device for cleaning items to be cleaned. The cleaning device has at least one fluid device for applying at least one cleaning fluid to the items to be cleaned. The cleaning device has at least one electrical load. The cleaning device further has at least one electrical connection for supplying electrical energy to the cleaning device. The cleaning device further has at least one energy store. The cleaning device is designed to receive electrical energy via the electrical connection and to temporarily store said electrical energy in the energy store. The cleaning device is further designed to supply electrical energy from the energy store to the at least one electrical load.
