Clothes dryer

The invention relates to a tumble dryer according to the preamble of claim 1.

In a known tumble dryer of this type (DE-AS 22 19 889) the drying air is through a fan in a closed circuit via an electric heater, a laundry drum and one in the housing below the laundry drum arranged condenser circulates, while a second fan circulates a stream of fresh air sucks in, blows through the condenser for cooling and then lets it flow out into the open. The im Condensate accumulating in the condenser is pumped out of a drain or flows into a drain to be emptied by hand Collecting container.

The invention has for its object to provide a tumble dryer of the type mentioned using the to further improve the available free space of the dryer.

The solution to this problem according to the invention is the characteristic of claim 1 can be found. The inventive Training of the tumble dryer made possible by relocating the condenser in the door Gain the space otherwise used by the condenser inside the dryer housing as usable space.

Advantageous embodiments of the invention are specified in claims 2 to 7. Will the Providing a capacitor in the door next to a capacitor in the housing is a major improvement the efficiency of the tumble dryer can be achieved without changing the dryer dimensions.

Embodiments of the invention are explained in more detail below with reference to the schematic drawing.

It shows: .

Fig. 1 ■ a section through the front Housing area of a clothes dryer according to the invention,

Pig. 2 shows another embodiment of the invention Tumble dryer, the section shown through the open door and the front housing base is laid

3 shows a further embodiment of the invention, with the door closed and a collecting container that protrudes into the door and can be pushed into a receptacle in the housing base.

In the housing 1 of a laundry dryer that can be loaded from the front, there is a laundry to be dried Drum 2 rotatably mounted. The loading opening in the front wall of the housing can be closed by a door 3. In the door 3 is an air-cooled condenser 4- arranged, which in the illustrated embodiment of a door is formed in two channels dividing heat exchange surface. For better utilization of the door space and for

To increase the heat exchange surface, the condenser can be constructed with several layers of heat exchange surfaces.

.A cooling air fan arranged in the base of the housing 1 7 sucks in fresh air through an opening 17 in the outer door wall into the cooling air duct 5 of the condenser. The cooling air flows through channel 5, sweeps the warmth exchange surface of the capacitor 4 and passes through a Transition point 6 in the housing to the cooling air fan 7 · From there the cooling air can either go into the installation room are conducted or enter a second capacitor, not shown, provided in the housing.

The circulated in a closed circuit by a hot air blower 11, used to dry the laundry After being heated, air is passed into the drum 2 by an electric heater (not shown). The dry air removes moisture from the laundry and the drum loaded with water vapor in the area of the loading opening Exiting exhaust air flows through a lint filter 8 and enters the drying air duct 9 of the door condenser 4-. Moisture is extracted from the exhaust air and the dehumidified dry air on the cooled heat exchange surface enters the housing again through a transition 10 sealed by the seal 18 when the door is closed Direction to the hot air blower 11. Located in the housing a second capacitor, so that can only partially dehumidified dry air flow can still be passed through this condenser before it is again the electrical one Heating happens.

The condensate accumulating in the door condenser can be caused by various Devices are derived. So the connection of the condensate drain line .of the door condenser to the drain line of the housing or to a collecting container 15 arranged in the housing consist of line ends, which, when the door is closed, are pressed tightly against one another or • can be coupled to one another.

According to Figure 2 is in the housing 1 in the vicinity of the door hinge 12, 13 of the collecting container 15 arranged,. into which an extended end 14 of the condensate discharge line of the door condenser 4 opens, the end of the line 14 analogous to the opening angle of the door 3 can be pushed more or less far into the collecting container. Of the Collection container 15 can by a pump 16 or from Hand emptied.

In Figure 3 is again.die door 3 with the heat exchange surface 4, the. Cooling air duct 5, the drying air duct 9 and the fans 7 _? 11 shown for the cooling or drying air. In this embodiment, the collecting container 15 is either attached to the door 3 or inserted into a receptacle 19 of the housing 1 so that it can be removed for emptying by hand. When the door is closed, there is a condensate drain opening 20 'of the door condenser above a filling opening of the collecting container.
