Description

[Detailed explanation of the invention] [Technical field of the invention] This invention has one side and back part of the case approximately L.
The present invention relates to an outdoor unit of an air conditioner formed by a letter-shaped fin guard.

[Technical background of the invention]

FIG. 1 shows the conventional structure of an outdoor unit of an air conditioner, and 1 is a bottom plate. This bottom plate 1 forms a substantially box-shaped case 7 together with a front panel 2, side plates 3, fin guards 4, top plate 5, and columns 6. Inside this case 7, an outdoor heat exchanger 8 bent into a substantially L shape, a blower fan 10 attached to a fan motor mounting frame 9, a partition plate 11, a compressor 12, etc. are arranged. ing. Further, the fin guard 4 is bent into a substantially L-shape as shown in FIG. 2, and forms one side and a back surface of the case 7.

[Problems with background technology]

The fin guard 4 is formed by connecting wires in a lattice shape, and has relatively low mechanical strength, so a reinforcing column 6 is attached to the case 7 separately from the fin guard 4. Therefore, the number of components of the case 7 increases, which makes the assembly work troublesome, and the support column 6 needs to be painted, which causes a problem of high cost.

[Purpose of invention]

The purpose of this invention is to provide an outdoor unit for an air conditioner that can reduce the number of parts, improve the efficiency of assembly work, reduce costs, and is suitable for small-volume production of multiple models.

[Summary of the idea]

A reinforcing plate-like frame is integrally provided at the bent part of the L-shaped fin guard formed by connecting wires in a grid pattern, and mounting holes for mounting the cabinet are formed at the top and bottom of this frame. It is something.

[Example of idea]

FIGS. 3 and 4 show an embodiment of this invention. FIG. 3 schematically shows the overall structure of an outdoor unit of a large-scale air conditioner of a multi-model, small-volume production type, and 21 is the bottom plate of the cabinet.
This bottom plate 21 forms a substantially box-shaped case (cabinet) 26 together with a front panel 22, side plates 23, fin guards 24, and top plate 25. Inside this case 26, there is an outdoor heat exchanger 27 bent into a substantially L shape, a blower fan 29 attached to a fan motor mounting frame 28, and a partition plate 3.
0 and a compressor 31, etc., are respectively provided. The partition plate 30 partitions the inside of the case 26 into a heat exchange chamber 32 and a machine chamber 33. An outdoor heat exchanger 27 and a blower fan 29 are arranged on the heat exchange room 32 side, and a compressor 31 is arranged on the machine room 33 side. Furthermore, an electrical component box 34 for storing various electrical components is attached to the upper part of the partition plate 30 on the machine room 33 side. The fin guard 24 is made by connecting wires in a lattice shape as shown in FIG.
It is bent into a letter shape. A reinforcing frame 35, which is formed by bending an iron plate into a substantially L-shape, is integrally provided at the bent portion of the fin guard 24 by means such as spot welding. in this case,
The fin guard 24 may be formed into a substantially L-shape by attaching separate members to both sides of the frame body 35, respectively. Furthermore, mounting holes 36 for mounting a cabinet are provided at the upper and lower ends of the frame 35, respectively. The fin guard 24 is disposed outside the outdoor heat exchanger 27 and is screwed to the bottom plate 21 and the top plate 25 through mounting holes 36 provided in the frame 35, respectively. In addition,
The fin guard 24 and the frame 35 are coated with a polyethylene coating, for example.

Thus, in the structure described above, since the frame body 35 is provided integrally with the fin guard 24 at the bent portion of the fin guard 24, the mechanical strength of the fin guard 24 can be increased compared to the conventional one. Therefore, the pillars 6 (shown in Figure 1) that were conventionally used to reinforce the case can be omitted, so the number of component parts of the case 26 can be reduced compared to the conventional case, and the assembly work can be made more efficient. can be achieved. Further, since the frame body 35 is coated together with the fin guard 24, there is no need for special painting, and cost reduction can be achieved. Furthermore, since the L-shaped fin guard 24 is formed by wire members connected in a grid pattern, the width and height of the fin guard 24 can be changed relatively easily by changing the length of the wire members. be able to. Therefore, when manufacturing multiple models of outdoor units with different overall sizes and shapes, the width and height of the fin guard 24 can be easily changed by changing the length of the wire member. Unlike when forming fin guards by punching sheet metal with a press machine, there is no need to provide a dedicated press mold for each model, and outdoor units of multiple models with different overall sizes and shapes can be formed. The work of manufacturing can be facilitated. Also, Finguard 24
Attachment holes 36 for mounting the cabinet are formed at the upper and lower parts of the plate-like frame 35 at the bent portion of the fin guard 24, so that when the fin guard 24 is attached to the cabinet, the plate-like frame 35 at the bent portion of the fin guard 24 is removed. can be first attached to the cabinet and then the end of each wire member can be attached to the cabinet. Therefore, the elasticity of each wire member of the fin guard 24 can absorb the installation dimensional error when the fin guard 24 is attached to the cabinet, so that the installation work of attaching the fin guard 24 to the cabinet can be facilitated. Furthermore, the process of attaching the ends of each wire member of the fin guard 24, which are easily deformed, to the cabinet is performed with the plate-shaped frame 35 of the bent portion of the fin guard 24 being attached to the cabinet, and the center portion of each wire member, which is easily deformable, is fixed. It can be done with
The workability of attaching the ends of each wire member to the cabinet can be improved.

5 and 6 show a structure of an outdoor unit different from that shown in FIGS. 3 and 4, and 41 is a bottom plate. This bottom plate 41 is bent into an L-shape and forms a case 45 together with a front panel 42 that also serves as one side plate, the other side plate 43, and a top plate 44. Inside this case 45, an outdoor heat exchanger 46 is disposed on the back surface, and a blower fan 48 attached to a fan motor mounting frame 47, a partition plate 49, and a compressor 50 are disposed, respectively. There is. The partition plate 49 is the case 4
5 is partitioned into a heat exchange room 51 and a machine room 52, in which an outdoor heat exchanger 46 and a blower fan 48 are arranged, and a compressor 50 is arranged in the machine room 52. There is. Furthermore, an electrical component box 53 is attached to the upper part of the partition plate 49 on the machine room 52 side.

Therefore, in the case of the above structure, the bottom plate 41, the partition plate 49, the fan motor mounting frame 47, and the front panel 42 are integrally formed in advance by means such as spot welding during assembly work. In this state, the blower fan 48 is screwed to the fan motor mounting frame 47, and the compressor 50
and an outdoor heat exchanger 46 are screwed onto the bottom plate 41, and the last side plate 43 and top plate 44
is about to be installed. Therefore,
A compressor 50 and an outdoor heat exchanger 4 are installed on the bottom plate 41 in advance.
After installing the 6th etc., the front panel 42 and the partition plate 4
Compared to the case where 9 etc. are attached, assembly work can be made easier, and the strength of the case 45 can also be increased, leading to cost reduction.

[Effect of idea]

According to this invention, a reinforcing plate-like frame is integrally provided at the bent part of an L-shaped fin guard formed by connecting wires in a lattice pattern, and mountings for mounting the cabinet are provided on the top and bottom of this frame. Since the hole was formed,
It has excellent practical effects such as reducing the number of parts, increasing the efficiency of assembly work, lowering costs, and being suitable for low-volume production of multiple models.
