US 7676954 B2Abstract
A drying method for a household appliance such as a dishwasher comprises a Peltier-element in addition to a heat-emitting part and also a heat-absorbing part for drying the washed items in the treatment area of the dishwasher. The heater-absorbing part cools a lateral wall of the washing container, which guides condensation of humidity into the air of the treatment area. Also, the air of the treatment area is circulated about an air channel by a blower and the air in the air channel is simultaneously heated with the aid of the heat-emitting part of the Peltier-element. The relative humidity of the air is reduced and the capacity of the air of the absorbing humidity is increased.
In household appliances it is generally necessary to dry the items to be treated. This is the case, for example, with washer driers and laundry driers as well as in particular in dishwashers. It is known that a dishwasher has a washing process whose program sequence normally consists of at least one pre-rinse partial program step, one clean partial program step, at least one intermediate rinse partial program step, a clear rinse partial program step and a drying partial program step. To enhance the cleaning effect, the washing liquid is heated before or during a partial program step. The washing liquid is usually heated by means of an electrical heater. Various drying systems are known for drying washed items, i.e. crockery, in a dishwasher.
It is thus the object of the present invention to provide a drying method for household appliances and a household appliance whereby the items to be treated in the household appliance can be dried efficiently in a short time with a low energy input.
The invention is explained hereinafter with reference to drawings as an example. In the figures:
FIG. 1 shows a cross-section through a dishwasher 1 according to the invention with a washing container 2. The washing container 2 encloses a treatment chamber 2 a in which crockery baskets with crockery (not shown) are located. The remaining parts of the dishwasher 1 according to the invention are not shown. The washing container 2 has a washing container sump 14. An outlet 3 is located in the upper region of a side wall of the washing container 2 and an inlet 4 is located in the lower region of the side wall of the washing container 2. The outlet 3 and the inlet 4 are interconnected by means of an air channel. The outlet 3 and the inlet 4 can also be arranged at any other location of the washing container 2. A blower 6 and possibly in addition a condenser 7 and a heater 8 are located in the air channel 5. The blower 6 circulates the air of the treatment chamber 2 a according to the direction of arrow 15. A reversed direction of circulation is also possible. The air is thus sucked out of the treatment chamber 2 a at the outlet 3 and blown into the treatment chamber 2 a again in the inlet 4. A Peltier element 10 composed of a plurality of single Peltier elements 10 a is arranged between the air channel 5 and a side wall of the washing container 2. The Peltier element 10 is, for example, a metal Peltier element or a semiconductor Peltier element. Peltier elements 10 have the property that when a DC voltage is applied, one side is heated and the other side is cooled, i.e. the Peltier element 10 thus has a heat-emitting part 12 (warm side) and a heat-absorbing part 13 (cold side). The heat-emitting part 12 of the Peltier element 10 is arranged in thermal contact with the air channel 5 and the heat-absorbing part 13 of the Peltier element 10 is formed in heat-conducting contact with the washing container 2. In addition to this arrangement, the heat-absorbing part 13 of the Peltier element 10 can be arranged on any other wall of the washing container 2. A contact plate 9 is preferably arranged between the heat-absorbing part 13 of the Peltier element 10 and the side wall of the washing container 2. The contact plate 9 has a very good heat-conducting capacity. The heat transmitting capacity from the heat-absorbing part 13 to the washing container 2 can thus be improved. If the contact plate 9 is larger than the Peltier element 10, the condensing surface in the washing container 2 can be improved. Optionally, it is also possible to dispense with the contact plate 9.
