Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a device for fixing an outer box to an underframe in an air conditioner.

Conventional Structure and Problems Conventionally, an outer box fixing device for this type of air conditioner has been structured as shown in FIGS. 1 to 3. That is, in the figure, 1 is a front grill forming the front surface of the air conditioner main body, and 2 is an outer box forming the outside of the air conditioner main body. On the front side of the outer box 2, flange portions 3 for fixing the outer box are provided at four upper and lower ends, and steps 4 for receiving the front grille 1 are provided on the top surface 5 and both left and right side surfaces 6a, 6b. It is being Further, the top surface 5 and both side surfaces 6a, 6b of the outer box 2 are provided with L-shaped bent portions 7, 8a, 8b, respectively. Reference numeral 9 denotes an air guider which forms a well-known air circuit together with an indoor heat exchanger and a blower (none of which are shown), and the front part of its outlet is bent into an L-shape 10. Insulating materials 11 and 12 are provided inside the air guider 9 and the right side surface 6b of the outer box, respectively.
are pasted facing each other without any gaps.

However, the outer box 2 has only four outer box fixing flange portions 3 in total on both upper and lower end surfaces.
The central portion of the outer box 2 is not fixed to anything. In addition, since the heat insulating materials 11 and 12 attached to the air guider 9 and the outer box right side plate 6b are attached facing each other without any gaps, they are pushed against each other, and the center portion of the outer box 2 is pushed outward. This bulges and creates a gap between the heat insulating materials 11 and 12, reducing the sealing performance, and since the air guider 9 forms an indoor wind circuit, there is a drawback that dew condenses in this gap during cooling operation. was.

Purpose of the invention The present invention is intended to eliminate the drawbacks of the conventional outer box fixing device described above, and aims to prevent the outer box from bulging and prevent dew condensation.

Structure of the invention In order to achieve this purpose, the present invention has developed a slit and a U-shaped hook in the central part of the side surface of the outer box and the underframe, respectively, which constitute the main body of the air conditioner, which is equipped with a heat exchanger, a blower, etc. and one end of the hook part is hooked to the slit.

This configuration prevents the outer box from bulging.

DESCRIPTION OF EMBODIMENTS The present invention will be described below with reference to FIGS. 4 to 6 of the accompanying drawings showing one embodiment of the invention.

In the figure, 2 is an outer box forming the outside of the air conditioner main body. On the front side of the outer box 2, outer box fixing flange portions 3 are provided at four locations on the upper and lower end surfaces, and steps 4 for receiving a front grille (not shown) are provided on the top surface 5 and both left and right side surfaces 6a, 6b. It is being In addition, L-shaped bent portions 7 and 8 are provided on the top surface 5 and both side surfaces 6a and 6b of the outer box 2, respectively.
a and 8b are provided. Said outer box right side 6b
Almost at the center of the L-shaped bend, there is provided a receiving part 6c in which the step 4 is extended without the L-shaped bend,
This receiving portion 6c is provided with a slit 6d. Reference numeral 9 denotes an air guider that forms a well-known wind circuit together with a blower 10, an indoor heat exchanger, etc. (not shown), and the front part of its outlet is bent into an L-shape 11. A hook portion 12 bent into a letter shape is provided and inserted into the slit 6d. Said air guider 9
Insulating materials 13 and 14 are pasted on the inside of the right side surface 6b of the outer box, facing each other without any gaps.

Therefore, in this embodiment, since the hook portion 12 of the air guider 9 is hooked to the slit 6d in the center of the outer box 2, even if the heat insulating materials 13 and 14 are pushed against each other, the outer box 2 and the air guider 9 is constant, sealing performance is improved, and since there are no gaps, no dew condensation occurs during cooling operation.

Effects of the Invention As is clear from the above embodiments, the air conditioner outer case fixing device of the present invention is applied to the central part of the side surface of the outer case and the underframe that constitute the air conditioner main body, which is equipped with a heat exchanger, a blower, etc. A slit and a U-shaped hook are provided in each of the slits, and one end surface of the U-shaped hook is hooked to the slit, so that the gap between the outer box and the underframe is constant and sealing performance is maintained. It also has various effects such as preventing dew condensation from forming in gaps during cooling operation.
