Abstract

The invention relates to a dishwasher (1) in the form of a programmable automatic machine, which has a programme control device (50) for carrying out at least one treatment programme, a treatment chamber (2) into which and from which wash ware can be manually inserted and removed, a tank (4) into which fluid from the treatment chamber (2) can flow off by gravity, and a washing system (33, 8, 34, 10) with a washing pump (8) and with a washing line system (10) for conveying washing fluid (6) during a washing phase out of the tank (4) through washing nozzles (33, 34) into the treatment chamber (2). In order to achieve an efficient treatment (cleaning and drying) of the wash ware, along with as low a consumption as possible of resources in terms of water, chemicals and, in particular, energy, there is provision, according to the invention, for the dishwasher (1) to have, furthermore, a wash-ware detector device (51) which is designed for detecting the type of wash ware to be treated, furthermore the programme control device (50) being designed to select a predetermined or determinable treatment programme for at least the washing phase automatically as a function of the detected type of wash ware to be treated and to set the process parameters associated with the selected treatment programme.

Description

Invention field [0001] The invention relates to a dishwasher and a method for cleaning cleaning parts in the dishwasher. [0002] In particular, the present invention relates to a method for cleaning cleaning items in a dishwasher, especially a commercial dishwasher, which is designed as a programmable automated machine. The invention also relates to a dishwasher in the form of a programmable automated machine, in particular a commercial dishwasher. [0003] Dishwashers that can be manually loaded and unloaded are programmable automated machines. Programmable automated machines (called box-type warewashers or other sequential conveyor dishwashers) can be push-in dishwashers, also known as hood-type warewashers, or front-loaded warewashers machine. The front-end loader can be a machine located under the counter, a machine on the counter, or other independent front-end loader.

Problems solved by technology

[0011] If a preset program in the factory is used in the processing of cleaning parts (the preset program is usually designed in a compromise so that the program can be more or less efficient for various types of cleaning parts), then light highly soiled utensils, such as drinking glasses, are washed longer than necessary and at a higher temperature than necessary, which is uneconomical

On the other hand, wash items with relatively difficult food residues, such as kitchen utensils and / or knives, run the risk of being insufficiently cleaned and, in some cases, require more than one cleaning of these wash items. Secondary cleaning or additional manual cleaning
