Description

[Detailed Description of the Invention] The present invention relates to a louver device for an air blower, and is intended to improve the ease of attaching fins for directing the air.

This type of louver device is comprised of a horizontally long louver frame in which an air outlet is partially opened, and fins attached along the lateral direction of the frame. For example, in a louver device in a hot air heater, if the fins 6 have a shape extending perpendicularly to the hot air outlet surface of the louver frame 5 as shown in FIG. As a result, the heating efficiency is poor, so normally the entire fin 6 is formed in a shape that is inclined downward with respect to the hot air outlet surface as shown in FIG. I'm trying to improve.

However, if the entire fin 6 is inclined with respect to the hot air outlet surface in this way, when the fin 6 is bonded and fixed to the louver frame 5, welding and caulking problems may occur, such as the welding tool 16 shown in the figure being unable to be inserted into the joint surface. It had a drawback that made it very difficult to work with.

Therefore, in view of the above-mentioned conventional circumstances, the present invention provides a louver device for an air blower that can satisfy both the direction of air blowing by the fins and the ease of attaching the fins by simply improving the shape of the fins. It is something.

Hereinafter, one embodiment of the present invention will be described based on FIGS. 1 to 4.

In FIGS. 1 and 2, 2 is a main body case of the heating device, and 1 is a heating heat source provided in the main case 2, such as an electric heater or a part that emits combustion heat from a kerosene combustor. 3 is a blower fan, 4 is a louver device according to the present invention, and includes a horizontally long louver frame 5 fixedly attached to the entire width W of the upper front surface of the main body case 2, and a fin attached along the lateral direction of the frame 5. It consists of 6. 7 is the front panel of the main case 2, 8 is the bottom plate of the main case 2,
9 is an indoor air intake, 10 is a partition plate that separates the heating heat source 1 and the ventilation fan 3, and this and the main body case 2.
It forms 11 wind channels. 12 is a mixing chamber in which indoor air from the blower fan 3 and warm air from the heating heat source 1 are mixed; 13 is a hot air outlet, which is opened in a horizontally elongated manner approximately in the middle of the louver frame 5; 14 is frame 5 of louver fin 6
At the joints to both ends 15 of the louver frame 5
It is joined by electric welding or caulking.

In such a hot air heating device, in the present invention, the portion of the fin 6 facing the hot air outlet 13 in the lateral middle portion thereof is formed in a shape that is inclined downward with respect to the outlet 13 as shown in FIG. On the other hand, the fin 6
The other portions, that is, both ends, are formed in a shape extending perpendicularly to the hot air outlet 15 as shown in FIG. Department.

According to the above configuration, the hot air outlet 1 of the fin 6
Since the shape of the portion facing 3 is formed to be inclined downward with respect to the hot air outlet 13,
Hot air is discharged downward into the room by the fins 6, improving heating efficiency, and at the same time, both ends of the fins 6 are formed in a shape that is perpendicular to the hot air outlet 13. As shown in Figure 4,
The welding tool 16 can be easily inserted between each fin 6,
This allows welding or caulking work to be performed extremely easily. Further, according to the above structure, since the fins 6 are formed over the entire width of the main body case 2, the design is aesthetically pleasing.

Although the above configuration shows an example in which the louver device according to the present invention is applied to a hot air heating device, it is needless to say that the louver device according to the present invention is not limited to this and may be applied to other air blowing devices such as a cooling device.

As explained above, according to the present invention, by simply improving the shape of the louver fins in a louver device, it is possible to simultaneously improve the direction of airflow and improve the ease of attaching the fins to the louver frame. This has a great effect.
