DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outdoor unit of an air conditioner having an improved structure for attaching a compressor to a main body.

[0002]

2. Description of the Related Art Conventionally, air conditioners have been widely used as devices for adjusting the temperature in a room. A typical air conditioner has an indoor unit installed indoors and an outdoor unit mounted outdoors. An outdoor unit of the air conditioner is provided with a compressor, a heat exchanger, and the like that constitute a refrigeration cycle.

[0003] Hereinafter, a mounting structure of a compressor in a conventional outdoor unit will be described. A plurality of bolts are fixed to the bottom plate of the outdoor unit body by spot welding. The compressor is mounted on a pedestal having an opening formed at a position corresponding to the bolt fixed to the bottom plate of the main body. In the process of mounting the compressor on the main body, vibration-proof rubber is inserted into each bolt fixed to the main body bottom plate, the opening of the pedestal where the compressor is mounted is passed through the bolt, and the nut is tightened for each bolt Was.

As described above, in an outdoor unit of a general air conditioner, a compressor is attached to a main body via a vibration-proof rubber,
The vibration generated during the operation of the compressor was absorbed by the vibration isolating rubber to prevent damage to the compressor body and piping.

[0005] Incidentally, a welding process for fixing the bolt to the bottom plate of the main body is required, and since the welding process is generally a troublesome process, assembly of the main body takes time and production efficiency is poor.

Therefore, a method of caulking and fixing a bolt to the bottom plate of the main body has been proposed (JP-A-11-210729).
No., JP-A-10-325569). In this method, a troublesome welding process is not required. Further, since the step of caulking and fixing the bolt to the main body bottom plate can be performed simultaneously with the press working of other parts, the labor required for assembling the main body can be greatly reduced.

[0007]

However, in the process of assembling the outdoor unit main body, when mounting the compressor, nuts are tightened for each bolt fixed to the main body bottom plate. On the other hand, inside the outdoor unit main body, not only the compressor but also many devices such as heat exchangers are installed, and since many mechanical parts such as piping connecting each device are densely packed, nuts are attached to each bolt. There is a problem that the workability of the tightening operation is poor, and the process of attaching the compressor to the apparatus body is troublesome.

In Japanese Patent Application Laid-Open No. Hei 10-47711, a pin hole is formed in one of the legs of the compressor, an opening is formed in the remaining leg, and the pin hole is fitted in the bottom plate of the main body. There has been proposed an outdoor unit in which a nut to be welded to a pin corresponding to an opening of the leg and the opening corresponding to the leg. In this outdoor unit, a pin fixed to the bottom plate of the main body is fitted into a pin hole of a leg, a bolt is inserted into an opening of the remaining leg, and the bolt is tightened to a nut welded to the bottom plate. The compressor is attached.

[0009] However, even in this method, the bolts are not required for the legs having the pin holes, and the bolts are required for the plurality of legs having the openings. There is a problem that it takes time to attach the compressor to the apparatus body. Moreover, since the nut was welded to the bottom plate, a troublesome welding process was required.

SUMMARY OF THE INVENTION An object of the present invention is to provide an outdoor unit of an air conditioner, which simplifies a process of attaching a compressor to an apparatus main body, thereby reducing the number of work steps required for assembling the main body and allowing easy assembly. It is in.

[0011]

An outdoor unit of an air conditioner according to the present invention has the following arrangement to solve the above-mentioned problems.

(1) A plurality of mounting members fixed to the bottom plate of the main body and having shaft portions protruding inside the main body, a vibration isolator inserted into the shaft portions of each mounting member, and corresponding to the plurality of mounting members. A compressor mounted on a pedestal having an opening at a location where
In the outdoor unit of an air conditioner in which the compressor is mounted by passing the opening of the pedestal through the shaft of each mounting member in which the vibration isolator is inserted, the plurality of mounting members include: 1
There was one in which the tip of the shaft portion was threaded, and a nut was fastened to the threaded mounting member.

(2) The bottom plate of the main body has an opening at a mounting position of the mounting member, and the mounting member has a convex plastic deformation portion at a head thereof. The plastically deformed part inserted in the opening was deformed, and the bottom plate of the main body was held between the plastically deformed part and the head.

(3) The outer peripheral shape of the composition deforming portion is polygonal.

(4) A plurality of projections are formed on the head of the mounting member on the contact surface with the bottom plate of the main body being fixed.

[0016] First, as described in the section of [Prior Art], in order to prevent damage to the compressor body and pipes due to vibrations generated during operation, etc. , So it is not fixed to the main body.

In the above configuration, the vibration isolator is inserted into a plurality of mounting members fixed to the bottom plate of the main body, and is passed through the opening of the pedestal on which the compressor is mounted. Here, among the plurality of mounting members fixed to the main body bottom plate, only one of which has a threaded end. The nut is tightened to a specific mounting member whose tip is threaded. This completes the attachment of the compressor to the main body. The remaining mounting members whose front ends are not threaded remain in the state of passing through the opening of the pedestal and do not have nuts or the like attached thereto.

As described above, since the compressor is mounted on the apparatus main body via the vibration isolator, the compressor is in a floating state with respect to the main body, and nuts are attached to all mounting members passing through the opening of the pedestal. There is no problem if you do not tighten the.
However, if the nuts are not tightened to all the mounting members, the opening of the pedestal will fall out of the mounting members when the main body is dropped, etc., and the compressor will roll over inside the main body, and the compressor main body and piping etc. It will be damaged.

In the apparatus according to the present invention, the nut is fastened to the specific mounting member whose tip is threaded, so that the opening of the pedestal does not come off from the mounting member when the main body is dropped. In addition, the compressor can be prevented from rolling over inside the main body. In addition, if a mounting member whose tip is threaded is fixed in a place where the density of components is low inside the main body, for example, in the vicinity of the outer peripheral portion of the apparatus main body, the nut can be relatively easily tightened. The compressor can be easily attached to the apparatus body.

As described above, in the above configuration (1), only the nut is tightened to the specific mounting member whose tip is threaded, so that the number of assembling steps for the apparatus body can be reduced, and as a result, the production efficiency can be reduced. The effect of cost reduction accompanying improvement can also be obtained.

Further, in the above (2), the mounting member is fixed to the bottom plate of the main body by press working, so that a troublesome welding step is unnecessary, and a decrease in production efficiency can be prevented.

Further, the shape of the mounting member is as described in (3) above.
With the shape shown in (4), the circumference of the mounting member fixed to the main body bottom plate can be regulated, and the reliability of the apparatus main body can be improved.

FIG. 1 is a schematic diagram showing a configuration of an outdoor unit of an air conditioner according to an embodiment of the present invention. As shown in FIG. 1, the air conditioner 1 of this embodiment has a compressor 2 attached to the right side of the main body and a fan 3 attached to the left side. The other mechanical parts are omitted.
The compressor 2 is attached to a triangular base 4 as shown in FIG. FIG. 2A is a front view, and FIG. 2B is a top view. The pedestal 4 has openings 4a at corners (three places). On the bottom plate 5 of the main body, mounting members 6 are fixed to locations (three locations) corresponding to the openings 4a formed in the pedestal 4, respectively.

FIG. 3 shows the mounting member 6. FIG. 3 (A),
3 (B) is a front view of the mounting member, FIG. 3 (C) is a top view, FIG.
(D) is a bottom view. Mounting member 6a shown in FIG.
Is a bolt having a shaft 11 formed on a head 11.
On the head 11, a plastic deformation portion 13 having a convex shape is formed on the opposite surface where the shaft portion 12 is formed, and a plurality of protrusions 14 are formed around the plastic deformation portion 13. . The attachment member 6b shown in FIG. 3B has substantially the same shape as the attachment member 6a, but differs in that a threaded portion 15 is formed at the tip. As described above, the mounting member 6 shown in FIG. 3 is fixed to the bottom plate 5 of the main body. Two mounting members 6a and one mounting member 6b, three mounting members 6 in total, are fixed to the bottom plate 5 of the outdoor unit 1 of this embodiment.

Here, the fixing of the mounting member 6 to the bottom plate 5 will be described. An opening is formed in the bottom plate 5 at a position where the mounting member 6 is fixed. The plastic deformation portion 13 of the mounting member 6 is passed through the opening of the bottom plate 5 (see FIG. 4A),
Thereafter, the plastic deformation portion 14 is deformed by press working (see FIG. 4B). By this pressing, the mounting member 6 is processed so that the bottom plate 5 is sandwiched between the head 11 and the plastically deformed portion 14 (fixed to the bottom plate 5). Further, as shown in FIG. 4B, the plurality of protrusions 14
Is pressed into the contact surface (upper surface in the figure). Therefore, the periphery of the mounting member 6 fixed to the bottom plate 5 is regulated,
Play is less likely to occur in the mounting member 6. As is well known, if an appropriate jig is used, three mounting members 6 can be simultaneously mounted on the bottom plate 5 by one press working, so that it is compared with a method in which the mounting members 6 are fixed to the bottom plate 5 by spot welding. If this is the case, the labor involved in the process is greatly reduced.

Further, 3 is fixed to the bottom plate 5 of the main body.
Of the attachment members 6, the attachment member 6 b having a threaded end portion selects and fixes a portion where the density of components is low inside the main body. In FIG. 1, 3 for fixing the mounting member 6.
Attachment member 6 at the position closest to the side plate of the device body
The example which fixed b was shown.

Next, a process of attaching the compressor 2 to the main body will be described. As shown in FIG. 2, the compressor 2 is mounted on a pedestal 4. The openings 4 a formed in the pedestal 4 correspond to the positions of the three mounting members 6 fixed to the bottom plate 5. The operator passes the opening 4 a formed in the pedestal 4 through each mounting member 6 fixed to the bottom plate 5. In addition, the anti-vibration rubber 7 is already fitted in each of the mounting members 6 fixed to the bottom plate 5. Thereafter, the nut 8 is fastened to the mounting member 6b whose tip is threaded. Thus, the attachment of the compressor 2 to the main body is completed.

Since the nut 8 is not tightened for the mounting member 6a whose tip is not threaded, the number of steps is reduced by that much compared to the conventional one. Further, since the mounting member 6b whose tip is threaded is selected and fixed at a location where the density of components is low inside the main body, the work of tightening the nut 8 to the mounting member 6b can be performed relatively easily. Thereby, the process of attaching the compressor 2 to the main body can be performed very easily, and the labor involved in the process can be greatly reduced.

Further, since the rotation of the mounting member 6 fixed to the bottom plate 5 of the main body is restricted by the projections 14, the mounting member 6 fixed to the bottom plate 5 is hardly rattled, and the reliability of the apparatus main body is improved. it can.

Further, since the nut 8 is fastened to the mounting member 6b whose tip is threaded, the opening 4a of the pedestal 4 does not come off from the mounting member 6 when the main body is dropped, and the inside of the main body is not removed. Can prevent the compressor from rolling over. Therefore, damage to the compressor body, piping, and the like can be prevented.

Since the compressor 2 is mounted on the main body 1 through the vibration isolating rubber 7, the compressor 2 is in a state of floating with respect to the main body 1, so that the three mounting members fixed to the bottom plate 5 are provided. There is no problem if the nuts 8 are not tightened to all 6.

In the above embodiment, the projection 14 is formed on the head 11 to restrict the periphery of the mounting member 6 fixed to the bottom plate 5, but as shown in FIGS. 5A and 5B. If the external shape of the plastic deformation portion 13 is a polygonal shape such as a triangle or a quadrangle, rotation can be prevented without providing the projections 14. 5A and 5B are bottom views of the mounting member 6 (a front view and a top view are omitted). In this case, a polygonal opening corresponding to the outer shape of the plastic deformation portion 13 is formed in the bottom plate 5 at a position where the mounting member 6 is mounted.

In the above embodiment, the number of the attachment members 6 fixed to the bottom plate 5 is three, but may be four or five.

[0034]

As described above, according to the present invention, the labor required for the process of attaching the compressor to the main body can be greatly reduced, and as a result, the effect of reducing the cost of the apparatus main body can be obtained.

Further, since the mounting member is fixed to the bottom plate of the main body by press working, a troublesome welding step is not required, and the assembling step of the main body can be performed more easily.

Further, since the periphery of the mounting member fixed to the bottom plate of the main body is regulated, the reliability of the main body of the apparatus is improved.
