A dishwasher (), in particular a commercial dishwasher (), which is in the form of a box-type dishwasher and has a treatment chamber () 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 () is designed to detect the type of washware to be, wherein the washware detector apparatus () 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.

Dishwasher and method for cleaning washware in a dishwasher

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

Conveyor dishwasher and method for operating a conveyor dishwasher

A dishwasher, in particular a commercial single-tank dishwasher or commercial multi-tank dishwasher, for washing washware includes a liquid transportation line () with at least one supply line for supplying liquid at a first temperature and comprising at least one discharge line for discharging liquid at a second temperature. The supply line and the discharge line run coaxially in relation to one another, so that either the supply line or the discharge line forms an internal line () which runs in the direction of extent of the liquid transportation line () within the respectively other supply line or discharge line which for its part forms an external line (), and thereby form a countercurrent heat exchanger.

Dishwasher having a liquid transportation line

A dishwasher has a wash system with a nozzle system with at least one wash nozzle for spraying wash liquid, a wash tank, and a wash pump by means of which wash liquid collected in the wash tank is fed to the at least one wash nozzle. A dirt-collecting system has at least one tank-covering screen to separate off particles of dirt from the wash liquid. The dirt-collecting system also has a dirt-collecting region arranged in the wash system and is intended for collecting the particles of dirt which have been separated off from the wash liquid with the aid of the tank-covering screen, wherein the dirt-collecting region is open at the top, but closed all the way around the sides, and wherein there is also a dirt-discharging pipe system by means of which the particles of dirt collected in the dirt-collecting region are discharged from the wash system.

Conveyor warewasher having an automatic wastewater removal system

A dishwasher in the form of a programmable machine, in particular a commercial dishwasher, having a pre-cleaning station, which is disposed outside a treatment chamber of the dishwasher, and having a waste water transfer system, by which washing liquid can be fed from a wash tank of the dishwasher as pre-cleaning liquid to the pre-cleaning station.
