Abstract

Um den Energieverbrauch eines Geschirrspülers zu reduzieren, wird die Wasserentkalkungsvorrichtung (20) als Wärmespeicher eingesetzt. Beispielsweise wird am Schluss der Hauptreinigungsphase dem Prozesswasser Wärme über einen ersten Wärmetauscher (28) entzogen und über einen zweiten Wärmetauscher (29) dem Solewasser zugeführt. Die Wärme wird später in der Zwischenspül- oder Klarspülphase über die beiden Wärmetauscher (28, 29) wieder teilweise an das Prozesswasser zurückgeführt.

In order to reduce the energy consumption of a dishwasher, the Wasserentkalkungsvorrichtung (20) is used as a heat storage. For example, at the end of the main cleaning phase, heat is withdrawn from the process water via a first heat exchanger (28) and fed to the brine via a second heat exchanger (29). The heat is later returned partly to the process water via the two heat exchangers (28, 29) in the intermediate rinsing or rinsing phase.
