Embodiment Construction

[0037]The dishwashing machine 110 has a dishwashing chamber 112 in which items to be cleaned 114 can be placed. Furthermore, there is a nozzle system in the dishwashing chamber 112, comprising washing nozzles 116 and final washing nozzles 118. This nozzle system is in this case illustrated by way of example as a system of spraying arms arranged above and below the items to be cleaned 114. However, alternatively or additionally, it is also possible to provide different types of nozzles.

[0038]Furthermore, the dishwashing, machine 110 has a washing tank 120 which is designed to hold a washing liquid 122. The washing tank 120 may, for example, be equipped with one or more supply lines 124, for example in order to fill the washing tank 120 with fresh water and / or in order to supply a cleaning agent or dishwashing agent to the washing tank 120. In the illustrated exemplary embodiment, the washing tank 120 is in the form of a separate washing tank, although embodiments are also feasible in...

Abstract

A dishwashing machine for commercial use to clean items cyclically has at least one tank for holding a dishwashing liquid, as well as at least one heating apparatus for heating the dishwashing liquid, and at least one temperature sensor for detecting the temperature of the dishwashing liquid. The dishwashing machine also has a controller being designed in order to control heating of the dishwashing liquid in at least one program step in a dishwashing program, with the heating being carried out at least until a predetermined intended temperature is reached. In this case, before or during an initial heating phase, a start temperature of the dishwashing liquid is detected, the minimum heating duration being determined from the start temperature. The heating process is then carried out accordingly with this minimum duration.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is based on German Patent Application No. 10 2007 005 834.0 filed 1 Feb. 2007, upon which priority is claimed, and on Provisional Application 60 / 907,302 filed on Mar. 28, 2007.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The invention relates to a dishwashing machine for commercial use, and to a method for controlling a dishwashing machine for commercial use.[0004]2. Prior Art[0005]Commercial dishwashing machines are used in various areas in which relatively large amounts of items to be cleaned have to be cleaned within a short time. These items to be cleaned may, in particular, be in the form of glasses, flatware, plates and dishes, containers, trays, saucepans and cooking pans, kitchen utensils or similar other objects.
