Abstract

A method which allows items, contained in a processing chamber, to be effectively and efficiently dried from an economical point of view and the energy consumption to be thus maintained as low as possible, despite a very high drying power. The method includes subjecting a medium in a container to at least one of an evaporation step and a sublimation step, whereby the medium is cooled, and absorbing via a reversibly dehydratable material in a sorber vapor produced by the medium in the container, whereby the reversibly dehydratable material is thereby heated. Air supplied from a processing chamber to the cooled medium is cooled and dehumidified. This air is then heated via contact with the reversibly dehydratable material and fed back into the processing chamber.

Claims (8)

1. A method for drying in a dishwasher, the method comprising:

(a) subjecting a medium in a container to at least one of an evaporation step and a sublimation step, whereby the medium is cooled;

(b) absorbing vapor, that is produced by the medium in the container, via a reversibly dehydratable material in a sorber, whereby the reversibly dehydratable material is heated;

(c) supplying air from a processing chamber of the dishwasher to the cooled medium, whereby the air is cooled and dehumidified via contact with the cooled medium; and

(d) heating the cooled and dehumidified air on the reversibly dehydratable material and feeding back the heated air into the processing chamber of the dishwasher;

the method further comprising:

heating the reversibly dehydratable material for desorption to condense the medium vapor that has been released via the desorption of the reversibly dehydratable material in the container whereby the medium is heated, and passing air from the processing chamber to the reversibly dehydratable material and back into the processing chamber, whereby the air is heated; and

desorbing the reversibly dehydratable material in the sorber via thermal energy and applying at least a portion of the thermal energy to at least one of the items to be processed and a processing liquid, wherein the items to be processed are heated during a partial program step that is a clean step or a pre-rinse step, and wherein the processing liquid is a washing solution or a non-washing solution.
