The invention relates to a device in dishwashers with a program control and cooling surfaces for precipitating the steam occurring in the wash cabinet.

It is already known that the steam occurring in the washing area of dishwashers is carried out by appropriate openings in the wall of the washing area to be diverted to the outside or to be sucked out with a fan. Such arrangements have the disadvantage that the steam outside of the washing area either on parts the dishwasher or in the area where it is installed.

It has therefore been proposed, as is known, the steam discharged from the wash cabinet within the Housing of the dishwasher on suitable surfaces, for. B. in a channel system to condense. However, such measures are relatively expensive and do not lead to rapid unwinding suitable for the wash cabinet. In addition, they still occur in undesirable places in the wash cabinet Build-up of condensation that drips onto the dried dishes and thus lead to staining.

In a further known proposal, the steam occurring in the wash cabinet should be thermally knock down the uninsulated outer walls of the wash cabinet. On these walls, however, arise during the entire wash program due to the lack of thermal insulation undesirable heat losses, which have to be compensated for by additional heating of the rinsing liquid. aside from that the condensation effect is low, because the walls before the steaming of the wash cabinet through the Rinsing liquid are heated.

In a further known dishwasher, a mixing chamber is provided between the washing chamber wall and the outer wall, in which the moist air discharged from the washing chamber is mixed with dry outside air. In doing so, the moisture content of the air flowing out of the washing area should be condensed. However, the condensation effect of such an arrangement is limited and in particular is not sufficient to condense the steam occurring in the drying phase, so that spotless drying and the items to be washed are not possible.

The object of the invention is to create a way to counteract the problem that develops during rinsing To condense steam in the wash cabinet of a dishwasher so that the dishes are heated during washing dries quickly and without spots.

According to the invention, this object is thereby achieved in dishwashers

solves that the cooling surfaces are formed by a water veil generated on the inner wall surfaces of the wash cabinet are. In one designed according to the invention

ao dishwasher is at least one wall of the Covered with a veil of water, on which the occurring steam condenses and that Condensate is washed away. Since the temperature of the items heated up during washing and the Wasserschleiers is very different, the wetting of the wash ware evaporates very quickly and is reflected again on the water veil on the wash cabinet wall. This will make a rapid Spotless drying of the wash ware achieved. Above all, it is prevented from being in the deck area condensation water collects in the wash cabinet and drips onto the dishes that have already dried.

To create a water veil, it is advantageous to run along the upper side of the rear wall of the wash cabinet and / or the side walls can be arranged at least one tube, the openings, for. B. slots and which is connected to a fresh water supply line. The connection of the water veil Generating pipe with the fresh water supply takes place advantageously via a program control operated valve.

The drawing shows an exemplary embodiment of a dishwasher designed according to the invention shown.

In the upper wall area of the washing area 1 of a dishwasher 2, which is passed through a washing area door 3 is closed, a pipe 4 is arranged, which is connected to a fresh water line, not shown communicates. In the tube 4 suitable openings are arranged through which the below the The wall surface located in the pipe 4 is sprinkled in such a way that a water veil 6 is created along the wall 5,

on which the steam that develops in the washing area 1 during the washing and drying of the items to be washed is deposited and condensed. The condensate is pumped out with the water that forms the veil.
