Description

[Detailed Description of the Invention] (a) Technical Field The present invention relates to an air conditioner such as an oil hot air heater, and more particularly relates to an improvement in the mounting structure of a front panel.

(b) Conventional Structure The conventional air conditioner housing shown in FIG. Slit-shaped engagement holes 4 are formed at both ends of the main body 1, and mounting fittings 5 are attached to the lower portions of both left and right ends of the main body 1. After the locking protrusions 7 protruding from the upper surface of the front panel 6 are engaged with the engagement holes 3'a of the top plate 3, the mounting ears 8 provided on the left and right sides of the lower surface are connected to the mounting bracket using screws 9. 5, and the front panel is attached and fixed to the front opening 2 of the main body 1.

(c) Problems with the conventional method In this case, since the part that is tightened and fixed by the screws 9 is located at the lowest end of the front panel 6, it is difficult to tighten and remove the screws 9 when attaching and detaching the panel 6, and it is difficult to tighten and remove the screws 9 during the manufacturing process. It was also causing problems when tightening screw 9. Furthermore, in the above method, when aligning the screw holes 10 of the mounting ears 8 of the front panel 6 and the screw holes 5' of the mounting bracket 5, it is necessary to lift the front panel 6 upward and fasten the screws. This required a lot of effort for the workers.

(d) Purpose of the present invention This application focuses on the above points and aims to improve workability and ensure assembly accuracy.

(E) Examples of the present invention This will be explained based on FIGS. 1 to 6.

12 is a main body having a front opening 13, left and right side plates 14, 14 and a rear plate 15 formed of a single plate;
A top plate 16 is provided at the top, and a bottom plate 17 is placed at the bottom.
is attached, and the front end of the top plate 16 protrudes 20 to 30 mm beyond the side plates 14, 14. A heat exchanger and a blower are provided within the main body 12.

Reference numeral 18 is a front panel which is provided with a hot air outlet 19 and the like as necessary and is attached to the front opening 13 of the main body 12, and has a peripheral wall 20 bent inwardly on the four sides of the periphery by drawing processing. A locking piece 21 projects downward from the rear end of the lower side of the peripheral wall 20, and has notches 22 at both left and right ends thereof. 2
3 is a screw 24 drilled in the upper part of both sides of the peripheral wall 20.
This through hole 23 is a stopper hole, and the periphery of this through hole 23 forms a bulging portion 25 that bulges inward. 26
is a plastic decorative sash attached to cover the upper peripheral wall 21.

Reference numeral 27 denotes an L-shaped support fitting that engages with 22 corner notches of the locking piece 21 of the front panel 18, with its rising front side 27a slightly protruding from the side surface of the main body 12. It is fixed to the bottom plate 17. This support fitting 27 is the locking piece 2
2 (see Figure 3) and the front panel 18
It also has the function of supporting the lower part of the front panel 18 and restricting movement of the lower part of the front panel 18 in the left-right direction (see FIG. 4).

28 corresponds to the through hole 23 of the front panel 18, and the front part 14' of the side plates 14, 14 of the main body 12;
This fastener 28 (see Fig. 6) has a screw hole in a fastening piece 28b that is formed integrally with the fastening piece 28a at right angles to it (see Fig. 6). 29 is provided,
Further, the screw hole 29 is bent outward so as to elastically abut the inner surface of the peripheral wall 20 of the front panel 18 (particularly the inner surface of the bulging portion 25).

Due to the elastic contact of this stopper piece 28b, the screw 24
Since the upper part of the front panel 18 is temporarily fastened when fastening the front panel 18, the screws can be easily fastened by simply placing a hand on the front surface of the front panel 18, making the work very easy. Also, the screw position is panel 1.
8, and in that respect also the front panel 1
8 becomes easier to fix. Furthermore, since the head of the screw 24 is exposed on the side, the appearance does not deteriorate compared to the conventional case where the head is exposed on the front. Further, the locking piece 21 of the front panel 18 can hide the distance between the bottom plate 17 and the lower side of the peripheral wall 20 of the front panel 18.

Further, since the pivot point of the front panel 18 is located inside the lower end, the front panel 18 can be mounted with almost no gap between the sash 26 and the top plate 16.

(f) Effects of the invention This invention has solved the problems of the conventional method and improved workability and assembly accuracy.
