The covering apparatus is movable over an opening travel from a closed position into an opened position or vice versa. The covering apparatus is connected via at least one force transmission path to at least one spring element. At least one spring force of the spring element can be transmitted by means of the force transmission path to the covering apparatus. The force transmission path has at least one torque converter. The torque converter has a transmission ratio which varies over the opening travel.

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 dishwasher (1), in particular a commercial dishwasher (1), which is in the form of a box-type dishwasher and has a treatment chamber (2) which can be closed and in which washware can be treated in accordance with a predefined or predefinable treatment program, wherein a washware detector apparatus (51) is designed to detect the type of washware to be, wherein the washware detector apparatus (51) has an optical identification system, which is oriented toward the washware to be treated, and an evaluation device, wherein the optical identification system is designed to record at least a portion of the light reflected by the washware to be treated as a reflection image, and wherein the evaluation device is designed to automatically distinguish between different types of washware on the basis of the recorded reflection image, wherein the extent of the reflection provides information about the type of washware.

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 dishwashing machine is used for pre-rinse operation of soiled dishes. A cavity is configured and arranged to contain the soiled dishes. A nozzle is proximate the cavity and is in fluid communication with the cavity. An accumulator pan accumulates wash and rinse water including cleaning chemicals used in a previous cycle of the dishwashing machine. A fluid passageway interconnects the nozzle and the accumulator pan. A pump directs the accumulated wash and rinse water from the accumulator pan to the nozzle via the fluid passageway for pre-rinse operation of the soiled dishes in the cavity, and the nozzle directs the accumulated wash and rinse water into the cavity with the soiled dishes to assist in removing soil from the soiled dishes prior to a wash cycle of the dishwashing machine. The wash cycle utilizes fresh wash water.

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 includes movable front, left, right and top wall sections, and is movable between a lowered and closed position for washing and a raised open position for inlet and outlet of wares. A stationary chamber rear wall includes an outlet opening fluidly connected with a vapor extraction unit at a back side of the rear wall. The vapor extraction unit includes an enclosure with a condenser therein, wherein incoming water to the machine from a cold water input passes through the condenser, wherein the enclosure includes an air outlet to surrounding ambient environment and at least one air mover.

A support frame for a basket in a cleaning tank is attached to a lifting member to raise and lower the basket and also two vertical stabilising members to prevent unwanted movement of the basket when asymmetrically or heavily loaded, which may lead the basket to jam against the sides of the tank. The stabilising members run in guides external to the tank and include skids or wheels for low friction movement. Further rollers attached to the baskets prevent it from fouling against the inside surfaces of the tank.

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.

A warewash machine includes a wash zone having front, left and right access openings. At least one spray arm is disposed above or below the wash zone. A multi-sided hood assembly includes front, left, right and top side sections, the multi-sided hood assembly movable between a lowered closed position for washing and a raised open position for inlet and outlet of wares. The multi-sided hood assembly includes a lower hood unit with front, left and right sides and an upper hood unit with front, left, right and top sides, and a linkage assembly between the lower hood unit and the upper hood unit that causes the upper hood unit and the lower hood unit to move up or down together with the lower hood unit moving faster than the upper hood unit to cause telescoping of the upper hood unit and the lower hood unit as the hood assembly moves.

A batch dishwasher is realized as a hood-type dishwasher having a treatment chamber (2) with at least one recirculating wash system for spraying wash liquid in the treatment chamber (2), and has at least one final rinse system for spraying final rinse liquid in the treatment chamber (2). The treatment chamber (2) has a first treatment zone (6) and at least one further, second treatment zone (7), wherein items of washware can be treated independently of one another and at least temporarily at the same time in the first and in the at least one second treatment zone (6, 7). The two treatment zones (6, 7) are physically separated from one another by a partition (50) such that when wash liquid is sprayed in one of the two treatment zones (6, 7), recontamination in the other treatment zone (7, 6) is effectively prevented.
