Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a warm air heater using oil, gas, etc. as a fuel, particularly to mounting a front panel.

<Prior Art> Conventionally, in this kind of thing, for example, Jitsuko Sho 59-635
As disclosed in Japanese Patent Publication No. 6, the front panel is attached to the frame by attaching the top end of the front panel to the top of the frame because of the ease of assembly and the aesthetic problem of making the screws as invisible as possible. It was carried out by engaging with the blowing grill and fixing the lower end to the frame with three screws.

<Problems to be solved by the invention> By the way, in this conventional one, since the front panel is fixed only at the upper and lower ends, when viewed from the side, a gap is inevitably formed in the middle portion, so that the leakage of combustion air or combustion gas does not occur. This is a cause, and because the screw is exposed on the front of the main body of the instrument by all means, it is detrimental to the aesthetic appearance.In recent years, so-called warm-air blowing with a blowing grill at the bottom has become the mainstream. There was also a problem that the installation of the front panel did not work.

<Means for Solving Problems> This invention focuses on this point and solves the above-mentioned drawbacks. In particular, the structure is such that a top panel and a front panel are attached to an integrated frame having both side surfaces and a back surface integrated with warm air. In the structure of the frame of the heater, the front panel has tongue pieces projecting to the back side inserted into the insertion holes formed in the flange and the lower plate of the front of the integrated frame, and The parts are attached by screws on the side of the integrated frame, and the insertion holes are formed in alternate stairs so that the tongue pieces generate elastic force.

<Operation> The front panel 6 is mounted by mounting the upper panel 4 on the integral frame 2 and then facing the tongue piece 8 protruding to the back side of the front panel 6 from the flange 9 and the lower plate 7 on the front side of the integral frame 2. The tongue pieces 8 of the front panel 6 are inserted into the insertion holes 10 respectively formed in the front panel 6 and finally the mounting tongue pieces 8 provided on both upper sides of the front panel 6 are passed through the flange portions 9 to form both side surfaces of the integrated frame 2. This is completed by fixing with the screw 13 in accordance with the screw hole 12 formed in the above. At this time, the tongue piece 8 inserted into the insertion hole 10 is staggered according to the shape of the insertion hole 10 only. As the tongues 8 are bent and inserted, elastic forces are generated by the stresses in the opposite directions of the step edges of the insertion holes 10 in the opposite directions, so that the tongues 8 are firmly and securely held. The front panel 6 as a whole will be attached well and there will be gaps. It is easy to assemble, and there are only two screws on both sides, which are not visible from the front and are aesthetically pleasing.

<Embodiment> Next, a warm air heater according to the present invention will be described with reference to a preferred embodiment shown in the drawings.

1 is a frame body that houses a combustion mechanism (not shown) and the like inside,
It constitutes an indoor exhaust type hot air heater called a fan heater.

The frame body 1 has an integral frame 2 integrally forming both side surfaces and a back surface, a top panel 4 provided with an operation portion 3 that is inclined downward on the front surface and includes various displays and operation buttons, and blows out to the lower portion. A front panel 6 having a grill 5 and a lower plate 7 constituting the bottom part
It is composed of and.

Reference numeral 8 denotes a plurality of tongue pieces protruding to the rear side of the front panel 6, which are inserted into the flange portion 9 of the integral frame 2 and the insertion hole 10 formed in the lower plate 7 at a position opposed to the tongue pieces 8. Is to be locked between the integrated frame 2 and the lower plate 7, and the insertion hole 10
Are vertically long and staggered, and the space between the upper and lower opposite side edges 10a and 10b is equal to or smaller than the plate thickness of the tongue piece 8, and the tip portion is bent in a slightly staggered manner in accordance with the insertion hole 10. By the insertion of the tongue piece 8 described above, the vertical root side of the tongue piece 8 is pushed in, so that an elastic force is generated in the tongue piece 8 and the front panel 6 is securely locked.

Further, of the tongue pieces 8, the tongue pieces 8 protruding from both sides of the upper end portion on the back side of the front panel 6 are used for attachment, and penetrate through the through holes 11 at the upper end of the flange portion 9 to form screw holes 12 formed on both side surfaces of the integrated frame 2.
The front panel 6
Is fixed to the integral frame 2 only by fixing screws at two places on the side surface which cannot be seen from the front.

Reference numeral 14 is a guide hole formed in the center of the front surface of the lower plate 7. By inserting the tongue piece 8 formed vertically in the center of the lower surface of the front panel 6, the other tongue piece 8 is smoothly inserted into each insertion hole 10. It provides guidance for insertion.

Next, the mounting of the front panel 6 of this embodiment will be described.

First, after each mechanism is provided in the integrated frame 2 and the lower tray 7, the upper panel 4 is fixed to the integrated frame 2 and then the front panel 6 is attached, and the front panel 6 lowers the lower tongue piece 8 first. It is inserted into the insertion hole 10 of the plate 7 and elastically generated to be locked, and then the tongue pieces 8 on both sides are similarly inserted into the insertion holes 10 of the flange portion 9 of the integral frame 2 and at the same time the tongue piece 8 for mounting is attached. If the through hole 11 is also penetrated, the front panel 6 is securely locked to the integrated frame 2 and the lower tray 7, and even if the assembling operator releases his hand from the front panel 6, Holds the locked state, and in this state, screws 13 from both sides of the integrated frame 2
The front panel 6 is completely attached by screwing the tongue piece 8 for attachment with, and the tongue piece 8 and the insertion hole 10 are locked by the elastic force between the integrated frame 2 and the front panel 6. It can be installed well without any gaps, and one screw cannot be seen from the front of the main body of the instrument, which is very beautiful.
Moreover, it is easy to assemble, and no problem occurs even if it is blown out under warm air.

<Effect of the Invention> In short, the present invention is the one in which the upper panel 4 and the front panel 6 are attached to the integrated frame 2 having the both side surfaces and the back surface integrally formed to form the frame body 1 of the warm air heater. 6 inserts a tongue piece 8 projecting to the back side into an insertion hole 10 formed in the flange portion 9 on the front of the integrated frame 2 and the lower plate 7, respectively, and a part of the tongue piece 8 is screwed to the side of the integrated frame 2. It is attached at 13, and the insertion hole 10 is formed in alternate stairs so that the tongue piece 8 generates elastic force. Therefore, only the upper part is screwed to the side of the integrated frame, The panel is firmly attached, and there is no gap between the integrated frame and the front panel as in the past, and the front panel is securely locked by the engagement of the tongue and the insertion hole. It can be used without any worry about air and gas leaks. It is extremely easy to assemble and can be assembled efficiently.
