TECHNICAL FIELD OF THE INVENTION
The present invention relates to a louver provided at a hot air outlet of a hot air heater to control the direction of hot air.
[0002]
[Prior art]
Generally, in this type of hot air heater, a hot air is blown in the direction of the floor to reduce the temperature difference between the upper and lower portions in the room. That is, a hot air outlet is provided on the front side of the warm air heater main body, and a louver is provided at the hot air outlet to control the direction of hot air blowing. In this type of louver, the louver is attached so as to be inclined so that its tip is directed downward over the entire length of the louver, and is configured to guide warm air toward the floor surface (for example, see Patent Document 1).
[0003]
However, if the tip of the louver is inclined downward, not only will the upper surface of the louver be relatively conspicuous, but also the trailing edge of the louver may be visible even if the line of sight is relatively high. There is a disadvantage that the appearance of the heater is significantly impaired.

[Problems to be solved by the invention]
SUMMARY OF THE INVENTION An object of the present invention is to provide a louver for a warm air heater that can direct a blow direction of warm air downward without reducing the appearance of the warm air heater.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a hot air outlet provided at a hot air outlet formed on a front side of a main body for housing a heat source, and forcibly blown out of the hot air outlet by a fan provided inside the main body. A louver for controlling the wind direction of the main body, a lower piece extending in a horizontal direction with respect to the hot air outlet, and a lower piece positioned on both sides of the hot air outlet and connected to a rear edge of the lower piece, the lower piece being connected to the main body And a top piece folded at the front edge of the bottom piece toward the upper surface side of the bottom piece and having a rear edge inclined in a downward direction, at least a position facing the hot air outlet. The lower piece is provided with an inclined portion inclined at a predetermined angle in a direction in which a trailing edge of the lower piece rises.
[0007]
According to the present invention, at a position opposed to the hot air outlet, the upper piece is inclined in a direction in which a trailing edge descends, while a lower piece is predetermined in a direction in which the trailing edge rises by the inclined portion. Angled.
[0008]
As a result, the upper piece has a front edge higher than a rear edge due to its inclination, so that even when looking down from a relatively high position, it is difficult to see the upper surface of the upper piece. Therefore, by providing the upper piece on the upper part, the upper surface of the louver can be made inconspicuous. Moreover, the warm air blown out from the warm air outlet is guided in contact with the lower surface of the lower piece so that the front edge of the lower piece faces the floor along the inclined portion at a position lower than the rear edge. . As described above, according to the present invention, since the upper surface of the louver is inconspicuous, the blowing direction of the warm air can be directed downward without lowering the appearance of the warm air heater.
[0009]
In the present invention, in the lower piece, a pair of cuts extending from the rear edge of the lower piece toward the front edge are formed at least at the same interval as the width of the hot air outlet, and a gap between both cuts is formed. The lower piece is bent upward through the front edge or the vicinity of the front edge to form the inclined portion.
[0010]
By forming the inclined portion of the lower piece between both cuts, the inclined portion can be reliably separated and bent from a horizontal portion other than the inclined portion, and the inclined portion can be easily formed. it can.
[0011]

An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a front view of a hot air heater equipped with a louver of the present embodiment, FIG. 2 is an explanatory front view of the louver of the present embodiment, FIG. 3 is an explanatory plan view of the louver of the present embodiment, and FIG. FIG. 5 is an explanatory side view of the louver of the embodiment, FIG. 6 is an explanatory sectional view taken along the line VI-VI of FIG. 2, and FIG. 7 is an explanatory view showing a part of the louver. FIG. 8 is an explanatory view showing the operation of the louver.
[0012]
As shown in FIG. 1, the warm air heater 1 in the present embodiment includes a panel opening 4 at a position below the front panel 3 of the main body 2. The panel opening 4 is provided with a warm air outlet 5 in a part thereof, and is closed by a closing plate 6 in other parts. Although not shown, a heat source such as a gas burner and a fan that generates hot air by the heat of the heat source and blows out the hot air outlet 5 are provided inside the main body 2.
[0013]
A plurality of louvers 7 are arranged in the panel opening 4 at predetermined intervals in the vertical direction. The louver 7 is formed of a plate-like member extending in the left-right direction as shown in FIGS. 2 and 3, and has a lower piece 8 projecting in the horizontal direction as shown in FIG. At the rear edge of one end of the lower piece 8, a first connecting piece 9 bent downward is continuously provided, and at the rear edge of the other end of the lower piece 8, bent downward. The second connecting piece 10 is continuously provided. As shown in FIG. 2, a screw hole is formed in the first connection piece 9, and one side (left side in the figure) of the outer edge of the hot air outlet 5 is connected and supported by a screw 11 through the screw hole. Is done. A plurality of locking holes 12 are formed in the second connecting piece 10, and after a locking claw 13 formed by cutting and raising the closing plate 6 is passed through the locking hole 12, the engagement hole 12 is formed. The pawl 13 is connected to and supported by the closing plate 6 by bending the pawl 13.
[0014]
As shown in FIG. 5, an upper piece 15 formed by folding back via a folded portion 14 at the front edge of the lower piece 8 is provided continuously above the lower piece 8 of the louver 7. The upper piece 15 is formed so as to be inclined in a direction gradually descending from the front edge (the folded portion 14 side) to the rear edge.
[0015]
As shown in FIG. 3, the louver 7 has a guide portion 16 for guiding hot air at a portion facing the hot air outlet 5. A pair of cuts 17 are formed in the lower piece 8 located at both ends of the guide portion 16. As shown in FIG. 6, the lower piece 8 located on the guide portion 16 between the cuts 17 has an inclined portion 18 which is inclined in a direction gradually rising from the front edge (the folded portion 14 side) to the rear edge. Is formed.
In the present embodiment, the inclined portion 18 is inclined with an inclination of about 7 ° with respect to a horizontal portion of the lower piece 8 other than the guide portion 16.
[0016]
As described above, the pair of cuts 17 are provided at both ends of the guide portion 16 facing the hot air outlet 5, and the inclined portion 18 is provided in the lower piece 8 between the cuts 17, so that the top and bottom are reversed in FIG. As shown partially, only the lower piece 8 of the guide part 16 is separated from the horizontal part of the lower piece 8 other than the guide part 16, and the inclined part 18 in which the lower piece 8 is inclined through both cuts 17 is formed. The forming process can be easily performed. On the other hand, the upper piece 15 is maintained in a state of being inclined at substantially the same angle over the entire length of the louver 7.
[0017]
According to the louver 7 formed in this way, as schematically shown in FIG. 8, the inclined portion 18 of the lower piece 8 formed in the guide portion 16 facing the hot air outlet 5 allows the louver 7 to be separated from the hot air outlet 5. The blown hot air can be controlled in the direction of the floor surface. In addition, the provision of the inclined portion 18 allows the louver 7 to be attached to the panel opening 4 without inclining the entire louver 7 downward, and furthermore, the inclination that gradually descends from the front edge to the rear edge of the upper piece 15. Can be maintained, so that the upper surface of the louver 7 (the upper surface of the upper piece 15) is difficult to see even from a line of sight from a high position, thereby preventing the appearance from being deteriorated.
[0018]
Further, since the folded portion 14 can be maintained in a vertical plane along the front panel 3, the front surface of the folded portion 14 is inclined forward as in the case where the entire louver 7 is inclined downward. There is no problem that the upper edge protrudes from the vertical plane of the front panel 3, and it is possible to prevent the appearance from being deteriorated.
