VERFAHREN ZUR RUECKGEWINNUNG VON ABWAERME BEI EINER HAUSHALTGESCHIRRSPUELMASCHINE SOWIE DERARTIGE MASCHINE ZUR DURCHFUEHRUNG DES VERFAHRENS

摘要

In a dishwashing machine, a water reserve container (2) is thermally conductively connected with a rinsing container (1) of the machine for heat exchange purposes. The dishwashing machine may be operated employing a programme comprising preliminary rinse, cleaning, intermediate rinse, clear rinse and drying stages. The water in the container (2) is used partly for the preliminary rinse and partly for cleaning, and in the latter stage the part transferred to container (1) is heated to 65 DEG C. When the latter temperature is reached, the container may be re-filled with water, which is heated by heat exchange with the cleaning water in container (1). The water thus heated is partly used for the intermediate rinse and partly for clear rinsing in the following stages.
