Narrow construction induction device with angled outlet

The invention relates to an induction device in the preamble of claim 1 mentioned Art.

With such induction devices, which are usually below of windows so that their housing ceiling is in the. a small distance below the underside of the window, you have previously arranged the or the air outlets in the ceiling of the housing, since such devices the Blow out air in an upward direction to avoid unpleasant drafts in the room concerned to avoid and also to form an upward-flowing air curtain on the window.

A disadvantage of this arrangement of the air outlet openings is, however, that the cover of the housing of the induction device cannot serve as a shelf, because otherwise light objects, e.g. paper, can be blown away or objects that have been deposited reduce the amount of air blown out or distract you undesirably. Blowing out the air from openings in the ceiling of the device housing also makes at least in many cases it is impossible to attach curtains or sun protection devices in front of the windows. Also, you cannot arrange these known induction devices with their ceiling under window sills, because otherwise they the blown air would deflect horizontally into the room and, among other things, unbearable drafts would result.

It is therefore the object of the invention to address these disadvantages of the known induction devices in the preamble of the claim 1 should be avoided.

According to the invention, this object is achieved by the in claim 1 ^; specified features solved. \

Although it is possible in some cases, such as when the induction device is longer than the width of a |

The window, below which it is arranged, is only over a major part of the length of the device housing to provide the air outlets located there on the front side of the housing, while the other or the rest Housing longitudinal sections are provided with one or more air outlets on the ceiling side, it is particularly advantageous and expedient not to provide any air outlet openings in the ceiling, so that such a device is always suitable for installation under windows of any width and its entire housing ceiling can serve as a storage area, it is useful to make them flat and, if necessary, with a suitable support made of plastic, wood, stone or the like.

Such induction devices always have one or more air inlets for secondary air, which by blowing out Primary air is sucked into the housing interior from a primary air box arranged inside the housing. In the These secondary air inlets are usually located in the front and / or in the bottom of the device housing, which is

inventive induction device is also useful.

The induction device according to the invention is extremely suitable to be built particularly narrow, i.e. to have a shallow depth, since the width of the ceiling does not change '' according to that for sufficiently low blow-out speeds required width of the air outlet opening or openings must judge. You can therefore provide relatively large heights of the air outlet openings without disadvantage, the greater than the width of the ceiling and, if necessary, also lower blow-out speeds than with the induction devices that have been customary up to now allow for the same amount of blown air over a period of time.

In order not to disturb the front of the housing by protruding parts of the air outlet, the measure according to claim 9, if necessary in conjunction with the measure according to claim 7, is expedient. _f

An exemplary embodiment of the invention is shown in the drawing. Show it:

FIG. 2 shows a cross section of a detail of the induction device according to FIG. 1.

That in FIG. 1 on a wall 10 under a window 11 Induction device 13 arranged in a building space 12 has a box-shaped housing 14, the depth of which is substantially smaller than its height and length. His The length (perpendicular to the image plane) is greater than its height. This induction device 13 is extremely narrow and its housing 14 points to the front wall 16 in the upper Area its single air outlet 15 (Fig. 2) and below one or more inlet openings, not shown for secondary air, behind which one or more heat exchangers, also not shown, for Heating and / or cooling medium are arranged for heating or cooling the secondary air. The power output of the heat

Exchanger can be controlled on the air side or on the water side in a manner known per se. Also in this is cuboid housing in the usual way a primary air box, not shown, which blows out primary air, which sucks in the secondary air and which together with the secondary air through the rectangular air outlet 15 blown through in an almost vertical upward direction at the front, i.e. at the front of the device

will. The flat ceiling 17 of the device is free of any air passage openings, ie it is above theirs
The entire width and length are closed and can carry a flat, aesthetically pleasing flattening 21 that is matched to the room in terms of color and decor. When the sheet metal ceiling 17 through the plate 21 or in some other way
is faced or arranged directly under a window sill, it does not need to be treated in a visually appealing way and can be galvanized, for example.

You can also at the window 11 curtains, sun protection devices or the like above the induction device
hang up or arrange without disturbances caused by blown air or the air to be blown out being hindered or deflected in undesired directions,
for example, is blown between the window surface and the curtain.

The air outlet 15 which opens into the rectangular, flat front wall 16 of the housing 14 and extends completely or almost over the entire length of the housing 14 is
formed by a vertically directed flat shell 19 and slats 20 inserted into it. The upper horizontal wall 22 of the shell 19 forms a narrow section of the ceiling 17. The

In this preferred embodiment, the mouth 27 of the air outlet 15 is provided in the plane of the flat front wall 16 of the device housing 14, which is particularly advantageous. However, it is also possible to arrange the air outlet in such a way that it protrudes somewhat beyond the front wall 16 or, in special cases, is also set back somewhat. In particular, when a front panel or panel, for example a panel of the induction device arranged at a distance in front of the front wall of the device housing 14, is present / the air outlet can be extended up to it. An example of such an embodiment is shown in phantom in FIG. 1, where 33 denotes a vertical panel, 31 denotes the air outlet extended up to it, and 32 denotes an extended cover of the ceiling of the device housing.
