gerate has the particular advantage of »that these can be set up as required in the rooms according to the given requirements and thus also independent of a central hot air heating system are.

A warm air device particularly suitable for church heating of the genus mentioned above is for example known from the German utility model 19 17 872, in which the housing of this device is vertically cut Is designed L-shaped, the vertical part opens into an opening and is also L-fb'rmic, ver ^ running partition wall in a supply air duct and a warm air duct is divided. In this previously known Ge ^ The required air filter, the heating device as well as the fan housed in the horizontal part of the housing to which on the one hand the vertical Connect the supply air section and, on the other hand, the vertical warm air section. With this previously known design such a warm air device are the cross-sections however, both the supply air section and the warm air section relatively low, so that the incoming air as well The hot air that escapes also has a relatively high air speed to have.

The object of the present invention is to provide such

To train warm air device in such a way that both the supply air inlet and the hot air outlet is still sufficient have a large cross-section without significantly increasing the volume of the VJarml uf tgerätes will.

This object is achieved according to the invention in that the warm air device in cross-section rectangular, T-shaped or is also U-shaped, in which case the supply air duct and the supply air part and the warm air part at least partially vertical and the transition part located between these two parts are arranged horizontally.

In a particularly preferred embodiment, this The supply air inlet and the warm air inlet can be used with the hot air device arranged next to one another and through a wall that can be displaced transversely to the air inlet or to the air outlet be separated from one another in such a way that the passage cross-sections both the supply air part and the warm air part can optionally be varied. Here is it is then still expedient if the supply air enters and the hot air outlet through a shared grille are covered.

In order to achieve the most compact design possible, it is also advantageous if the heating device and the

Fan arranged in the upper aisle part and opposite the Supply air inlet or the hot air outlet in such a way through the Wall of the transition part are covered that possibly Objects falling through the grille can only fall onto this wall and thus damage it both the heater and the fan are excluded.

Is the cross-section of the hot air device according to the invention designed rectangular, so in this case the supply air part and the warm air part are useful for forming the transition part formed stepped in cross section.

Another possibility for the design of the warm air device also consists in the fact that this is designed T-shaped in cross section, in which case the supply air part and the warm air part to form the transition part with a Z-shaped cross-section formed and the sections adjacent to the transition part in each case in the horizontal direction over the transitional steeple protrude outside. In this case, both the heating device and the fan are expediently each adjacent to the transition part arranged in the lower section of the supply air part or the warm air part. According to another In the variant, the heating device extends in such a way "over the entire height of the lower section to the supply air part that

the incoming supply air initially in one direction and after being deflected in the lower section in the other direction flows through the heating device.

If, on the other hand, the warm air device has a U-shaped cross-section, so the supply air part and the warm air part each form the legs and the upper aisle part forms the bridge of this (j U-cross section. With such a U-shape of the invention

According to the hot air device, however, it is also possible that the Supply air part, the transition part as well as the warm air part are each formed so in cross-section L-shaped that the vertical sections of these three parts each are located under the "" air inlet or the hot air outlet, however, the three horizontal sections of these three parts are arranged one above the other, leaving free each a deflection of the air flowing through enabling air. passage openings. The heating device can then

The warm air device 1 shown in cross section in FIG. 1 is arranged in a room 4 located in the underfloor 2 of an assembly room 3 and has a housing 5 with a rectangular cross section with the heat-insulated outer walls 6. In this housing 5, a likewise heat-insulated, horizontally directed dividing wall and a further vertical dividing wall 8 standing on the same are also arranged, both of which extend over the entire cross section of the housing 5. By these partition walls and 8, the interior of the housing 5 is divided in a vertical supply air 9, a horizontal transition portion 10 and a vertical hot air portion 11. The related to the supply air 9 supply air inlet has 12, Aer to Warini ufttei 1 11 associated warml uftaustri tt against it

is denoted by 13. Both this supply air inlet 12 as well as the hot air outlet 13 are through a common grid 14 covered.

In the upper area of the supply air part 9, which has a step 15, there is also a 16 denoted at an angle. The air filter arranged in the direction of the arrows

incoming air must pass before it flows into the transition part 10 in the direction of arrow 18. In the opening 19 of the transition part facing the supply air part 9, a heating device denoted by 20 is arranged, to which the respectively provided heat transfer medium is supplied or removed via the lines 21, which are only shown schematically. Seen in the direction of flow 18, behind this heating device 20 in the transition part 10, a fan designated by 22 is arranged, the outlet opening 23 of which is surrounded by a vertical partition 24. This outlet opening 23 is then followed by the hot air part 11, which also has a step 25 and from which the air heated by the heating device 20 exits in the direction of the arrows 26 and reaches the assembly room 3 to be heated. ^;

If the partition 8 resting on the horizontal partition 7 is horizontally displaceable in the direction of the arrow 27, so it is possible to use the cross-sections a and b

The illustrated in Fig. 2 second embodiment of the Warm air device 1, on the other hand, has a T-shaped cross section, with the same components being replaced by the same Reference numerals are identified. In this case, the supply air part 9 and the warm air part 11 each have one Z-shaped cross-section, with the outer, the Transition part 10 facing sections 28 and 29 protrude laterally and also provided in this case Transition part Io protrude. With this design is the fan 22 is already arranged in the outer section 28 of the supply air part 9, the outlet opening 23 of this Fan 22 protrudes in cross section 30 of transition part 10. The heating device 20, which is also provided in this embodiment, is on the other hand on the opposite one End 31 of the transition part 10 is arranged and extends in such a way over the entire height h of the section 29 that through this heating device 20 also the one above the transition part 10 located passage cross section 32 is covered. This has the consequence that the air passing through the transition part 10 in the direction of arrow 18 initially once in the direction of arrow 33 through the heating device and then after the deflection in section 29 in the opposite

The embodiment of the warm air device shown in FIG. 3 1 has a U-shaped cross section, the supply air part 9 and the warm air part 11 each being the two vertical leg and the transition part 10 form the horizontal leg of the "U". The air inlet 12 and the Warm air outlet 13 are each covered by a special grille 35. Similar to that shown in FIG first embodiment are also in this design the heating device 20 and the fan 22 are arranged in the transition part 10.

Finally, FIG. 4 shows a variant of the U-shaped design of the warm air device 1, in which the supply air part 9, the transition part 10 as well as the warm air part 11 are each L-shaped in cross section and the horizontal sections with 36, 37 and 38 are designated. Here, the supply air part 9 and the transition part 10 have a common one with 39 designated partition, in the deflection area an air passage opening 41 for receiving the heating device 20 is incorporated. In the vertical section 42 of the transition part 10, however, the fan 22 is arranged, its outlet opening 23 already in the horizontal Section 38 of the warm air part 11 protrudes.
