Abstract
A dishwashing machine is provided with a washing compartment and with devices for washing dishes using a washing solution as well as with a sorption drying device, which is connected to the washing compartment in an air-conducting manner via an outlet of the washing compartment and via an inlet of the washing compartment and which comprises a sorption column containing reversibly dehydratable material, the outlet of the washing compartment being connected to the sorption drying device via an air duct. In order to obtain an optimized sorption drying device, the air duct is provided, at least in part, in the form of a condensing surface.
Claims24
A dishwashing machine comprising:
- a washing container;
- at least one device for washing crockery using a washing solution;
- a heating device;
- and
- a sorption drying device communicated with the washing container for a passage of air between the sorption drying device and the washing container, the sorption drying device containing a reversibly dehydratable material that operates to withdraw moisture from air during a passage of air through the sorption drying device, air exiting from the washing container via a washing container outlet into an air duct of the sorption drying device communicated therewith and thereafter flowing along a flow path through the sorption drying device and eventually exiting the sorption drying device to return to the washing container via a washing container inlet, and the air duct of the sorption drying device being configured at least in part as a condensation surface, wherein the condensation surface is formed by a heat-conducting connection to one of a heat-conducting connection to the washing container and a heat-conducting connection to ambient air.
A method for treating crockery disposed in a washing container, comprising:
- subjecting crockery to a washing, a rinsing, and a drying, wherein air is passed into contact with the crockery during at least one of the washing, rinsing, and drying and such air is thereafter guided to a sorption drying device communicated with the washing container for the passage of air between the sorption drying device and the washing container, the sorption drying device containing reversibly dehydratable material that operates to withdraw moisture from air during the passage of the air through the sorption drying device, crockery retained in the dishwasher being subjected to a drying after having undergone a treatment as a result of which moisture remains on the crockery with the drying including passing air from the washing container through the sorption drying device;
- flowing air from the washing container at least in part past a condensation surface in order to extract therefrom some of its moisture before the air, which still has a residual moisture content, is fed thereafter to the sorption drying device;
- and
- cooling the condensation surface with a condensation surface cooler.
A dishwasher comprising:
- a washing container;
- a crockery washer in the washing container;
- a heater that heats a washing fluid for the crockery washer;
- a sorption dryer containing a reversibly dehydratable material and a condensation surface in communication with the washing container;
- and
- a condensation surface cooler that removes heat from the condensation surface.
