Description

[Detailed description of the invention] This invention relates to the improvement of the display board of air-conditioning and heating equipment.In other words, the display board of the conventional air-conditioning and heating equipment has a hole formed in the frame a and a rear face of the display board C, as shown in Fig. 4. Locking body d prepared for
After inserting the locking body d, fix it by caulking the tip of the locking body d,
Also, as shown in Fig. 5, a locking body d, which has a fitting part e larger than the through-hole at its tip, is inserted into the through-hole and fixed.
However, the former method requires caulking work, which is time-consuming and unsuitable for mass production, and the latter method requires no effort and is easy to assemble the display board C, but the mating part e is not forced. Since it is inserted into a through-hole, there is a risk of the locking body d breaking, and since it is fixed by sandwiching the frame body a between the fitting part e and the back of the display board C, the fixation is uncertain and loose. The slight movement of the frame body a due to the drive of the air blower installed inside the frame body a causes noise and discomfort to the user.To prevent this rattling, the fitting part e is An intermediate device such as a gasket must be provided between the display panel C and the back surface of the display panel C, which is expensive and difficult to attach.

This invention focuses on this point and attempts to provide a display board for a heating and cooling device that eliminates the above-mentioned drawbacks.

Next, an embodiment of this invention shown in the drawings will be explained.
Reference numeral 1 denotes a frame body of a heating device, which is equipped with a combustion mechanism (not shown), a fuel supply mechanism (not shown), a blower device (not shown), etc. on the inside, and a grill 2 for discharging hot air on the upper front side. It has an operation part 3, and the operation part 3 is equipped with a power switch 4, an operation handle 5, a timer handle 6, etc. for controlling the power supply to each internal mechanism, and 7 is the name or model of the appliance. Alternatively, it is a display board made of synthetic resin or the like that displays the name of the manufacturing company, etc. in rich colors, and has a protrusion 8 protruding most outwardly at approximately the center on the back, and a locking body 9 with a diamond-shaped cross section. The two through holes 11, which are integrally formed and provided at the four corners, are located at the lower side of the frame 1, are slightly narrower than the overhanging part 8 of the locking body 9, and into which the upper and lower locking bodies 9 are respectively inserted. An elastic upright wall formed by bending both sides of the locking body protrudes inward and locks the locking body 9 when the locking body 9 is inserted at a height lower than the projecting portion 8 of the locking body 9.

This invention is constructed as described above, and the display board 7
When assembling the frame 1 to the frame 1, attach the locking body 9 to the through hole 11. If the through-hole 11 is wider than the overhang part 8 of the locking body 9, the locking body 9 will easily pass through the through-hole 11, but the width of the rising wall 10 will be larger than the width of the overhang part 8. Since it is narrower than the width, the locking body 9
gradually presses the rising wall 10 by the inclined surface. Therefore, since the rising wall 10 has elasticity, due to this pressure, it gradually spreads outward along the inclined surface and passes through the overhanging part 8 of the locking body 9. After passing, it returns to its original position and locks the locking body 9 to prevent it from being removed.The display board 7 can be tightly fixed to the contact body 1 and will not rattle and generate noise due to the drive of the blower device. In addition, since it is mounted by utilizing the elasticity of the rising wall 10, it can be easily mounted without requiring strong force.Also, since the rising wall 10 is shorter than the projecting part 8 of the locking body 9, the projecting part After passing through the locking body 8, the locking body 9 comes into contact with the lower inclined surface and can prevent the display board 7 from coming off forward by locking with the overhanging part 8, so that the display board 7 can be securely fixed. To remove the display board 7 from the frame 1, press the locking body 9 forward from the back side of the frame 1, and then assemble the display board 7 by pressing the locking body 9 forward from the back of the frame 1.
The display board 7 can be removed from the frame 1 by spreading along the inclined surface of the
It is very convenient that a damaged or dirty display board 7 can be easily replaced without having to keep it attached forever.

Although the rising wall 10 is here integrally molded with the frame body 1, it is not limited to this, and it goes without saying that it may be molded as a separate member.

As described above, this invention is equipped with a locking body 9 having an outwardly protruding portion 8 on the back side of the display board 7, and a through hole 11 is formed in the frame body 1, and the above-mentioned is provided near the through hole 11. A rising wall 11 that is slightly narrower than the overhanging portion 8 of the locking body 9 and has elasticity.
Since the locking body 9 is locked by the rising wall 11, the display board is tightly fixed to the frame due to the elastic action of the rising wall, and there is some wobbling, making noise when the blower is driven or the like. It is securely fixed without causing any discomfort to the person, and the fixing can be done by simply inserting the locking body into the through hole, and since the locking body is elastic, it can be secured with a strong force. It is possible to provide an inexpensive instrument that can be easily inserted without requiring a
