Abstract

The invention relates to a method for operating an appliance comprising at least one sub-program step “drying”, which permits appliances comprising at least one sub-program step “drying” to be operated in the most economic manner possible and permits the efficient drying of items with a minimum energy consumption. To achieve this, during the sub-program step(s) “drying”, air is conducted from a treatment chamber via a conduit system, in which at least one Peltier element is located, and the air is then recirculated to the chamber. During its passage through the conduit system, the air is cooled, moisture is removed and the air is subsequently reheated.

Claims (9)

1. A method for operating an appliance having a treatment chamber in which items are subjected to washing, rinsing, and drying programs, the method comprising:

(a) performing a wash program for washing of the items:

(b) performing a rinse program for rinsing of the items: and

(c) performing a dry program for drying of the items, the dry program comprising guiding air via a conduit system connected to the treatment chamber such that air is initially guided from the treatment chamber to the conduit system and is subsequently recirculated from the conduit system to the treatment chamber with (i) the air that has been guided from the treatment chamber to the conduit system initially being guided relative to a Peltier element having means for extracting heat from air passed therethrough, whereupon the air is cooled by its passage relative to the means for extracting means and, thus, the moisture absorption capacity of the air is reduced, (ii) the air having passed relative to the means for extracting heat subsequently being guided relative to a means for heating the air such that the air is heated, and (iii) the air thereafter being recirculated after such heating by the means for heating the air back to the treatment chamber.

2. The method according to claim 1 , wherein the air is conveyed by means of a fan.

3. The method according to claim 1 , wherein the air is cooled by means of the Peltier element.

4. The method according to claim 1 , wherein the air is heated by means of the Peltier element.

5. The method according to claim 1 , wherein the air is heated by means of a heater.

6. The method according to claim 1 , wherein the air is passed by a condenser.
