Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial field of application) The present invention provides a pair of left and right louver frames with louvers, and these holo-processed louver frames and louvers are attached to a case with screws. Louver device.

(Prior Art) Conventionally, for example, in a louver device provided on the front surface of a warm air heater, a pair of left and right louver frames are provided so that the hole provided in the louver and the hole provided in the louver frame are coaxial. The louver frame and the louver are hollowed and then screwed through the holes to attach the louver frame and the louver to the case.

(Problems to be Solved by the Invention) In the above-mentioned prior art, when the louver frame and the louver are attached to the case via the screws, the force of the screws is directly applied to the hollow portion provided on the louver, and this portion is broken or damaged. May occur. Further, since the screw force is applied to the contact portion between the hollow portion formed on the louver frame and the case, similar damage such as cracking occurs in this portion as well. For this reason,
In order to prevent the holo from being damaged, a screw with a special screw must be used, and it is difficult to control the tightening torque of the screw, which causes a problem that the cost cannot be reduced.

An object of the present invention is to solve the above problems and to provide a louver device capable of preventing damage to the holo when attaching the louver frame and the louver and reducing costs.

[Means for Solving the Problem] (Means for Solving the Problem) The present invention provides a first burring hole having an end surface projecting outward, at the end of the louver body, and a second burring hole projecting an inner end surface. Burring holes are provided in a pair of left and right louver frames, and the first and second burring holes are coaxially arranged to integrally form the louver frame and the louver body to be hollowed, and an end face The louver frame and the louver body are attached to the case via screws by the first and second burring holes shown on the hollow surface.

(Operation) With the above structure, the louver body is provided with the first burring hole having the end surface projecting outward, and the second burring hole having the end surface projecting inward is provided in the louver frame, and these are integrated. By doing the holo processing after doing,
By providing the holo reservoirs outside the first and second burring holes, the end surface can be represented by the holo surface. Therefore, when the louver is attached to the case via a screw, the screw comes into contact with the end surface of the second burring hole, and the hollow portion provided outside the second burring hole is cracked without the force of the screw. It can prevent damage such as. Also, since the end surface of the first burring hole can directly contact the case, it is possible to prevent damage to the holo of the holo reservoir provided outside the first burring hole, and the screw does not use a special screw. It is easy to manage tomosumomi and screw tightening torque, and it is possible to reduce costs.

(Embodiment) Next, an embodiment of the present invention will be described with reference to the accompanying drawings.

Reference numeral 1 denotes a warm air heater, which is provided with a case 3 having an open front surface on a stand 2. A front panel 4 is provided at each of upper and lower front parts of the case 3, and a space between these front panels 4 is provided. The louver 5 is attached. Further, a burner 6 and an oil pan 7 are provided in the lower part of the case 3, and a blower duct 8 is provided above the burner 6 so that the combustion gas generated in the burner 6 is blown for convection (not shown). ), And blows out from the louver 5. A push button 10 for continuous rotation is housed movably up and down in an operation panel 9 forming an outer shell provided on the top plate 3A of the case 3. 22 is the operation panel 9
It is a display nameplate attached to the upper surface of.

The louver 5 attached to the case 3 has a pair of left and right louver frames 23 provided with louver bodies 24 and 25 in multiple stages, and a mounting flange 26 is bent at the ends of the louver bodies 24 and 25. An end surface 27 is formed on the flange 26 of the louver body 24 that is formed and is arranged in the upper and lower stages.
Is provided with a burring hole 28 which is a first burring hole protruding outward. Note that the upper and lower louver bodies 24 have the same mounting structure, and only the upper side will be illustrated and described. A burring hole 30 that is a second burring hole having substantially the same shape as the burring hole 28 is formed in the upper and lower portions of the louver frame 23 in which the square holes 29 into which the flange 26 can be inserted are formed in multiple stages. The end 31 of the burring hole 30 is provided so as to project inward, and after the flange 26 is inserted into the square hole 29, the burver frame 23 is formed so that the burring holes 28 and 30 are coaxial.
It is backed on and fixed by spot welding etc.
Further, the flange portion 26 of the louver body 25 located in the middle is inserted into the square hole 29 and then backed to the louver frame 23 and fixed by spot welding or the like. Then, by hollowing these integrated louver frame 23 and louver bodies 24, 25, an end face 27 is provided outside the burring hole 28 to provide a holo accumulating portion 32, and an end face 31 is formed in the burring hole 30. In this case, a holo pool 33 is provided, and the burring holes 28, 3 previously formed in the case 3 are formed.
The mounting receiving hole 34 having a diameter smaller than 0 and the burring holes 28 and 30 are coaxially arranged, and the louver 5 is mounted to the case 3 through the screw 35. The edge 36 of the louver frame 23 is bent outward in a U shape.

Next, the operation will be described with respect to the above-mentioned configuration. The burring hole 28 having the end face 27 protruding outward is provided on the flange 26 of the louver body 24 arranged in the upper and lower stages, and the burring process is provided with the end face 31 protruding inward. The holes 30 are provided in the upper part and the lower part of the louver frame 23, and these are integrated and then hollow-processed, so that the burring hole 2
The end faces 27, 31 can be represented by the holo surface by providing the holo reservoirs 32, 33 outside the 8, 30 respectively.
Therefore, when the louver 5 is attached to the case 3 via the screw 35, the screw 35 can contact the end surface 31 of the burring hole 30, so that the screw 35 is attached to the holo reservoir 33 provided outside the burring hole 30. It is possible to prevent damage such as cracking without applying force. Further, since the end surface 27 of the burring hole 28 can directly contact the case 3, damage to the holo of the holo reservoir 32 provided outside the burring hole 28 can be prevented and the screw 35 does not use a special screw. Tomomi and the tightening torque of the screw 35 can be easily managed, and the cost can be reduced. Further, the louver 5 is securely fixed to the case 3 through the burring holes 28, 30 and has a diameter larger than that of the mounting receiving hole 34.
Since the outer peripheral portions of 28 and 30 are attached in a relatively free state, the fear of loosening of the screws 35 and cracks of the holo can be eliminated even by shock, vibration, etc. during transportation.

The present invention is not limited to the above embodiment,
Various modifications are possible.

[Effect of Invention] In the present invention, a first burring hole having an outwardly projecting end surface is provided at the end of the louver body, while a second burring hole having an inwardly projecting end surface is provided in a pair of left and right. The louver frame which is provided on the louver frame and is holographically machined by arranging the first and second burring holes coaxially is integrally provided with the louver body, and the end face is represented by the hollow surface. With the first and second burring holes, the louver frame and the louver body are attached to the case via screws, and the holo is prevented from being damaged when the louver frame and the louver are attached, and the cost is reduced. A louver device capable of achieving the above can be provided.
