Abstract: A dishwasher (1) for cleaning drinking vessels, wherein the dishwasher (1) has a treatment zone (3) and a conveyor apparatus (6) for conveying the items of washware (2) to be cleaned from an introduction region (4) of the dishwasher (1) through the treatment zone (3) to a removal region (5) of the dishwasher (1). The conveyor apparatus (6) is configured to convey a previously defined or definable group of items of washware (2) to be cleaned in batches from the introduction region (4) through the treatment zone (3) and then to feed the group of items of washware (2) as cleaned items of washware (2) to the removal region (5).

Abstract: A conveyor for transporting dishes, in particular drinking containers, through at least one treatment zone of a dishwasher and/or for feeding dishes to the dishwasher. The conveyor includes a circulating conveyor system, a plurality of retaining elements connected to the circulating conveyor system and configured in order to releasably receive and/or releasably retain drinking containers, in particular in a positively locking manner and preferably at least in a sectionally or partially positively locking manner, and a support system for at least partially and/or sectionally supporting the drinking containers, received by the retaining elements.

Abstract: 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).

Abstract: A rack for dishwashers, in particular for commercial dishwashers, is provided. With the aim of making optimum use of space in the rack, and of discharging residual water as best as possible, it is proposed, that the rack has a rack framework (20) with two directly adjacent set-down surfaces (SI, S2) which are intended for washware (10) and run parallel to one another in the longitudinal direction of the rack, wherein the set-down surfaces (S) are inclined in relation to the horizontal such that the surface normals (F1, F2) of the set-down surfaces (S 1, S2) diverge.

Abstract: A dishwasher (2) has a detecting device (4) for sensing at least one condition indicative of need for self-cleaning of the dishwasher. The detecting device (4) emits a signal in this respect, for example, to an indicating device (6) or to a control device (8). The control device (8) is designed for executing a self-cleaning program, for controlling: a) a device for supplying self-cleaning liquid, b) a circulating pump for circulating the self-cleaning liquid in the dishwasher, for cleaning parts of the same, and c) a device for emptying the self-cleaning liquid from the dishwasher following the self-cleaning operation according to step b).

Abstract: Commercial dishwasher, in particular for glasses. A hot-wash section and a cold-wash section are provided in order to provide either heated rinsing liquid or unheated rinsing liquid for the rinsing operation.
