A method for operating a recirculating chemical-sanitizing dishwasher includes filling a wash tank of the dishwasher with water, and performing a first cycle of washing by circulating the water through a wash chamber of the dishwasher. A partial drain is performed of a first amount of water from the wash tank, and new water (for example, rinse water) is added to the wash tank for a second amount of water approximately equal to the first amount. A second cycle of washing is performed by circulating the water through the wash chamber of the dishwasher.

An example soaker sink may include a sink basin that receives wash items therein and defines an inlet opening. The soaker sink may further include a manifold that defines an inlet opening, an interior that receives a fluid flow input via the inlet opening, and a plurality of outlets. The outlets may permit discharge of fluid from the interior of the manifold to the sink basin and may include at least a first outlet and may further include a common outlet dimension. The soaker sink may further include a pump fluidically coupled with the inlet opening of the sink basin and the inlet opening of the manifold to recirculate fluid from the sink basin to the manifold. A flow restrictor may be removably coupled with the first outlet and may be configured to modify a flow rate of the fluid discharged via the first outlet.

Proposed is ultrasonic spoon washing apparatus and method, which use ultrasonic waves generated by one or more ultrasonic oscillators provided on a vertical side wall of polygonal surfaces of a wash tub, so that spoons contained in a spoon support part rotating forward/in reverse may very efficiently and conveniently be washed while the number of revolutions changes for each washing stage, the apparatus including: a frame body; the wash tub mounted inside the frame body; one or more ultrasonic oscillators provided on an outer side of the vertical side wall; a forward/reverse rotation support part including a support shaft and a rotation support pipe; a spoon support part including a holder and a spoon accommodation container; a rinsing water supply part configured to spray the rinsing water together with a rinsing aid; and a wastewater and foreign material discharge part configured to discharge, to the outside, wastewater and foreign materials.

A box-type dishwasher (1), wherein the dishwasher (1) has a fresh-water connection (20) with a feed valve (21), wherein a water-treatment system with a reverse-osmosis device (22) is provided downstream of the feed valve (21) in order to treat, in particular as required, as least some of the fresh water fed to the dishwasher (1) via the fresh-water connection (20), wherein a backflow preventer (6) is provided between the feed valve (21) and the reverse-osmosis device (22) in order to prevent water from flowing back from the dishwasher (1) into a fresh-water-supply installation (100) which is, or can be, flow-connected to the fresh-water connection (20).

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 dishwasher (1) in the form of a commercial utensil washer or dishwasher which is designed as a batch dishwasher and is realized as a hood-type dishwasher, wherein the dishwasher (1) has a treatment chamber (2) with at least one wash system which is designed as a recirculation system, wherein 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).

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).

A conveyor dishwashing machine (1) has at least one washing zone (7), and at least one final rinse zone (8) which is connected downstream (as viewed in the transport direction (T) of the wash items) of the at least one washing zone (7). The conveyor dishwashing machine (1) has a transport apparatus for transporting the wash items through the treatment zones (6, 7) of the conveyor dishwashing machine (1) so that the wash items are situated at least in regions in a washing plane (5) which runs horizontally. The washing plane (5) is configured as a main washing plane, and there is at least one additional washing plane (6) in at least one of the treatment zones (7, 8) of the conveyor dishwashing machine (1), in which additional washing plane (6) wash items can be treated.
