METHOD FOR OPERATING A DISHWASHER
A method for operating a dishwasher is provided. A heated fluid is at least periodically applied to items to be washed that are supported in an interior of the dishwasher. In order to heat the fluid, air is first conducted through a drying material suitable for exothermic drying. Thereafter, the air, together with the heated fluid driven out of the drying material, is conducted through an outlet opening through which the air, together with the heated fluid driven out of the drying material, enters the interior of the dishwasher. The outlet opening is cooled.

19 . A method for operating a dishwasher, the method comprising:
at least periodically applying a heated fluid to items to be washed that are supported in an interior of the dishwasher;
in order to heat the fluid, first conducting air through a drying material suitable for exothermic drying and then conducting the air, together with the heated fluid driven out of the drying material, through an outlet opening through which the air, together with the heated fluid driven out of the drying material, enters the interior of the dishwasher; and
cooling the outlet opening.
20 . The dishwasher of claim 19 , wherein the dishwasher is a household dishwasher.
21 . The method of claim 19 , wherein the outlet opening is wet with a cooling agent in order to cool the outlet opening.
22 . The method of claim 21 , wherein the cooling agent contains water.
23 . The method of claim 21 , wherein the cooling agent is circulated in a closed circuit.
24 . The method of claim 21 , wherein the cooling agent is circulated by a circulation pump in order to apply the heated fluid to the items to be washed.
25 . The method of claim 24 , wherein the circulation pump is operated at a lower speed when the outlet opening is cooled than when the heated fluid is applied to the items to be washed.
26 . The method of claim 25 , wherein the air is conducted in a closed circuit from the interior of the dishwasher through the drying material and back through the outlet opening into the interior of the dishwasher.
27 . The method of claim 19 , wherein the air flows through the drying material by a forced throughflow.
