Disclosed a dishwasher, wherein dishes placed on a conveyor are washed, rinsed, and dried while being sequentially conveyed to a washing chamber, a rinsing chamber, and a drying chamber, the dishwasher including: a heat exchanger allowing hot air to be supplied to the drying chamber by heat exchange; a wash water tank in which water supplied to the washing chamber or the rinsing chamber is stored; and a spray device spraying water supplied from the wash water tank onto the dishes placed on the conveyor, whereby it is possible to save energy by providing a single heat exchanger to preheat wash water and rinse water and supply hot air to the drying chamber, and to improve circulation of wash water by a filtering device applied to a structure for reusing wash water, thereby improving sanitation of dishwashing.

A dishwashing system includes: a conveyor-type dishwasher that washes tableware in a washing machine main body while conveying the tableware by means of a conveyor; a robot device having a robot arm mechanism that is installed in the vicinity of a picking area outside of the washing machine main body in order to pick up tableware that is conveyed to the picking area by conveyors, and to transfer the tableware to a stock area; and a control device that generates an enabling signal relating to operations of the conveyors with respect to the dishwasher.

A warewash machine includes a chamber for receiving wares, the chamber having a spray zone with an associated spray system for spraying liquid onto wares passing therethrough and a collection tank below the spray zone. A strainer pan is located atop the collection tank and includes an optional first opening with an optional removable strainer bucket mounted therein and a second opening with a removable cutlery basket mounted therein. A method of washing cutlery with such a warewash machine is also described.

A silverware pre-washing and washing system made up of a unitary basin with one to five, and preferably three, vertically movable porous baskets arranged radially around a central vertical lifting and lowering mechanism. The base with unitary basin contains a quantity of washing fluid(s) into which each of the vertically movable porous baskets may be repeatedly immersed. The base cover defines cylindrical ports through which the baskets are raised and lowered. The porous baskets include perforation arrays to allow washing fluid to flow in non-linear paths through the silverware contained in the basket, thereby washing all sides of the silverware and beneficially re-arranging the silverware in the basket as the washing process proceeds.

A warewash machine for washing wares includes a chamber for receiving wares, the chamber having an inlet side, an outlet side, multiple spray zones between the inlet side and the outlet side, and a conveyor arrangement for moving wares along a conveyance path through the multiple spray zones in a ware travel direction. A prescrapping zone is located toward the inlet side of the chamber, the prescrapping zone having a blow-off system comprising a plurality of prescrapping nozzles and a compressed air feed line for delivering compressed air to the prescrapping nozzles.

A system for grasping and retaining dishware during a cleaning cycle. The system includes a grasping element and a receiving surface substantially adjacent to the grasping element. The grasping element grasps the dishware, and the receiving surface receives and retains the dishware during at least one stage of a cleaning cycle. The receiving surface rotates about an axis to convey the dishware to at least two unique locations. A corresponding method is also described herein.

A flight-type dishwasher or rack conveyor dishwasher has a conveyor apparatus (20) for conveying washware through individual treatment zones (11, 12, 13, 14, 15) of the conveyor dishwasher (1). The conveyor dishwasher (1) has a detection system (30) designed to detect the presence of washware or a washware carrier (7) in a predefined region (A) at an inlet (10) or at a feed (16) of the conveyor dishwasher (1). A control device (50) is designed to actuate the conveyor apparatus (20) such that the conveyor apparatus (20) is activated when washware or a washware carrier (7) is detected in the region (A) at the inlet (10) or feed (16) of the conveyor dishwasher (1), and that the conveyor apparatus (20) is deactivated when no washware or no washware carrier (7) is detected in the region (A) at the inlet (10) or feed (16) of the conveyor dishwasher (1).

Dishwashing machine including an outer casing with an inner washing cavity adapted to accommodating a dishwasher rack. A catchment sink assembly is located on the bottom of the inner washing cavity to collect and accumulate liquid trickling down from the dishwasher rack momentarily located above the catchment sink assembly. The catchment sink assembly includes a basin-shaped catchment tank. A cup-shaped drain sump extends downwards from the bottom of the catchment tank and directly communicates with the inside of the catchment tank to receive washing or rinsing liquid arriving on the bottom of the catchment tank. A tubular member communicates with the catchment tank and is detachably fitted into a corresponding tubular outlet portion in the drain sump to divide the inner volume of the drain sump into a first inner-volume portion directly connected to a water drain line, and a second inner-volume portion directly connected to the suction of the pump.

A conveyor dishwasher (1) for washing washware has at least one final rinse zone (30, 40) and at least one washing zone (10, 20) whichas seen in the conveying direction (T) of the washwareis arranged upstream of the at least one final rinse zone (30, 40). A sensor device (5) is provided for detecting at least one parameter which characterizes the quality of the liquid which is to be sprayed in the at least one washing zone (10, 20), wherein the conveyor dishwasher (1) has a liquid transfer system which is designed, for the purpose of regenerating the washing liquid which is to be sprayed in the at least one washing zone (10, 20), to preferably as required supply an in particular definable quantity of fresh water to the at least one washing zone (10, 20).
