Abstract

A dishwasher includes a washing container, devices for washing dishes by means of rinsing liquor, and a sorption drying device which is connected in an air-conducting manner to the washing container via an outlet of the washing container and an inlet of the washing container. The sorption drying device is provided with a sorption column encompassing reversibly dehydratable material and is disposed between a wall of the washing container and an exterior housing wall of the dishwasher.

Claims (20)

1. A dishwasher, comprising:

a housing having an outer housing wall;

a washing container having an inlet, an outlet, and a washing container wall;

a device to wash crockery in the washing container with a washing solution; and

a sorption drying device connected to the washing container via the inlet and the outlet of the washing container in an air-conducting manner, the sorption drying device arranged between the outer housing wall and the washing container wall and having a sorption column that includes reversibly dehydratable material to dry the crockery, wherein the sorption column is concentrically arranged around at least one of the inlet and the outlet of the washing container;

wherein thermal energy for desorption of the sorption column is utilized to heat up at least one of the washing solution and the crockery in the washing container.

2. The dishwasher of claim 1 , wherein at least one of air from the washing container and ambient air is directed through the sorption column and into the washing container during a partial program step of the dishwasher that heats up the washing solution.

3. The dishwasher of claim 2 , wherein the partial program step of the dishwasher is at least one of a partial program step “clean”, a partial program step “pre-wash”, and a partial program step “clear wash”.

4. The dishwasher of claim 1 , further comprising a heating element to desorb the reversibly dehydratable material and to heat up at least one of the washing solution and the crockery.

5. The dishwasher of claim 4 , wherein the heating element is concentrically arranged around at least one of the inlet and the outlet of the washing container.

6. The dishwasher of claim 4 , further comprising a pipe connecting the washing container to the sorption column, and wherein the heating element is arranged in one of the reversibly dehydratable material and the pipe.

7. The dishwasher of claim 1 , wherein at least one of the inlet and the outlet of the washing container has passive sealing means to prevent water intrusion through the at least one of the inlet and the outlet.

8. The dishwasher of claim 1 , wherein at least one of the inlet and the outlet of the washing container has active sealing means.

9. The dishwasher of claim 8 , wherein the active sealing means is structured to be actuated by an active sealing means voltage applied to the active sealing means.

10. The dishwasher of claim 9 , wherein the sorption drying device comprises a fan, and wherein, when a fan voltage is applied to the fan, the active sealing means voltage is applied to the active sealing means.

11. The dishwasher of claim 10 , further comprising a temperature-sensitive memory metal to actuate the active sealing means.

12. A dishwasher, comprising:

a washing container having an inlet and an outlet;

a device to distribute a washing solution in the washing container so as to wash crockery in the washing container;

a sorption drying device connected to the washing container via the inlet and the outlet of the washing container in an air conducting manner and having a sorption column that includes reversibly dehydratable material to dry the crockery in the washing container, wherein the sorption column is concentrically arranged around at least one of the inlet and the outlet of the washing container.
