The present application provides a heat exchange device and a dishwasher. The heat exchange device includes an evaporator, a first liquid storage tank, a second liquid storage tank and a power unit. A medium inlet and a medium outlet are defined in the evaporator, the first liquid storage tank is in communication with the medium inlet, and the second liquid storage tank is in communication with the medium outlet and the first liquid storage tank. A liquid inlet and a gas discharge port are defined in the second liquid storage tank. The power unit is arranged between the evaporator and the first liquid storage tank, or between the evaporator and the second liquid storage tank, so as to drive a liquid medium to circularly flow between the first liquid storage tank, the evaporator and the second liquid storage tank.

A dishwashing appliance includes a cabinet, a cabinet door for opening and closing the cabinet, a tub provided in the cabinet, the tub defining a wash chamber, an outlet defined at a first portion of the tub, an inlet defined at a second portion of the tub, an air flow duct defined between the inlet and the outlet, wherein air enters the air flow duct from the tub via the outlet and exits the air flow duct to the tub via the inlet, and an access panel removably attached to the air flow duct, the access panel defining a mounting plate protruding from an interior surface of the access panel.

The present disclosure relates to a dishmachine that includes one or more features directed to water, energy or material savings. The disclosed dishmachines are still capable of meeting the soil demands of the articles to be cleaned.

A warewash machine includes a chamber with a wash zone and front, left and right access openings. At least one spray arm is disposed to spray liquid toward the wash zone. A multi-sided hood assembly is movable between a lowered and closed position for washing and a raised open position for inlet and outlet of wares. An air exchange system is provided for extracting hot water vapor from the chamber and for providing heated air into the chamber.

A conveyor dishwasher (1) has at least one wash zone (11, 12) in which wash liquid is sprayed onto the washware, at least one final rinse zone (14) in which final rinse liquid is sprayed onto the washware and a waste air system (20) for discharging waste air from the conveyor dishwasher (1). To save energy and maintain hygiene performance, a waste water heat recovery system (25) is provided for transferring at least a portion of the thermal energy in the waste water from the conveyor dishwasher (1) as useful heat to the final rinse liquid and a waste air heat recovery system is further provided for transferring at least a portion of the thermal energy in the waste air which is discharged or is to be discharged from the conveyor dishwasher (1) as useful heat to at least the final rinse.

A method for reducing energy consumption by a medium heating device, the method comprising the step: scheduling an operation (501) of the first device (111) requiring heating of a first medium; scheduling an operation (502) of the second device (112) requiring heating of a second medium; the method being characterized in that it further comprises the steps of: sending (504), from the first device (111), information regarding its operation cycles and water parameters to the second device (112); rescheduling (505) operations of the liaised devices (111, 112) so that drain heat of the first medium is reused to heat a fresh intake of the second medium by the second device by means of a heat exchanger (160); instructing (506), the reprogrammed devices (111, 112) to start their operations according to the new schedule.

A dish washing machine including a housing having an interior wash space for washing dishes. The housing has a liquid inlet for adding a liquid to the dish washing machine. At least one spray nozzle sprays the liquid onto dishes positioned within the interior wash space. The machine further includes a heating tank for heating the liquid which is supplied to the at least one spray nozzle for spraying onto the dishes in the interior wash space. At least one heat exchange system is within the housing. The at least one heat exchange system transfers heat from the liquid heated by the heating tank to the liquid added to the dish washing machine from the liquid inlet.

A conveyor ware washer (1), having a conveying device for conveying wash ware through treatment zones, has at least two wash zones (11, 12, 13), arranged one after the other and at least one final rinse zone (14) arranged downstream of the wash zones. An exhaust air system (20) removes exhaust air from the conveyor ware washer. The wash zone which is arranged closer to the final rinse zone has a heating device (40) for heating the wash liquid, which is to be sprayed in the relevant wash zone, to a minimum process temperature. A heat pump system transmits at least part of the thermal energy of the exhaust air, which has been removed or is to be removed from the conveyor ware washer, as useful heat to the wash liquid of the wash zone which is arranged further away from the at least one final rinse zone.

A dishwasher includes a reservoir for storing washing fluid, and a control device configured for calling up at least one dishwashing program for controlling a washing cycle for washing items to be washed in a washing chamber and at least one preheating program for controlling a preheating cycle for preheating washing fluid for a washing cycle separately from each other. The preheating cycle includes a heating phase during which washing fluid is circulated and the circulated washing fluid is heated. The preheating cycle has downstream of the heating phase a pumping phase during which previously circulated and heated washing fluid is pumped into the reservoir.
