[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a compressor mounting structure in an outdoor air conditioner.

[0002]

2. Description of the Related Art Conventionally, as a structure for mounting a compressor of this type, for example, one shown in FIG. 2 has been known (Japanese Patent Laid-Open No. 2-150636). The compressor 21 has a cylindrical shape and is arranged laterally, and the left and right edges 22a and 22b of a rectangular plate 22e having four circular holes 23 are bent upward to be fixed to the bottom of the compressor 21 and then bent downward. Front and back edges 2
2c, 22d has a bracket 22 for mounting in which square holes 24, 25 are provided. On the other hand, the bottom frame 26 is made of synthetic resin and integrally formed with the following members. That is, the L-shaped engaging portions 27, 27 fitted on the left and right corners of the front edge 22c of the bracket 22 and the plate-shaped square hole 2 that abuts the rear edge 22d.
8a, and the circular hole 2 of the bracket 22
4, four pillars 29 loosely fitted from below, and a vertical guide 30 for guiding the fixing metal fittings 33 from below, left and right, respectively.
A horizontal guide 31 and a positioning portion (not shown) for positioning and fixing the lower end of the fan motor mount 32 are integrally formed on the bottom frame 26.

Then, the four pillar portions 23 of the bottom frame 26
The lower spring support, the vibration-proof spring 34, and the upper spring support are sequentially fitted onto the respective upper and lower ends, and the bracket 22 of the compressor 21 is mounted and mounted so that the circular holes 23 are mounted on the four upper spring supports. From the location of the fixed protrusion 26a at the center of the front edge of the bottom frame 26, the above-mentioned vertical and horizontal guides 30 and 31 guide the two square holes 24 and 25 of the bracket 22, and the square hole 28a of the locking portion 28 of the bottom frame 26. And, the plate-like fixing metal fitting 33 is inserted into the square hole 32a of the fan motor mount 32,
The front end of the fixing bracket 33 is fixed to the fixing protrusion 26a with a screw. Here, the fixing bracket 33 is the square hole 2 of the bottom frame 26.
4, 25 is loosely fitted, and the other square holes 28a, 32a are tightly fitted. Therefore, excessive vibration of the compressor 21 and the bracket 22 mounted on the vibration-proof spring 34 against the bottom frame 26 is fixed as described above. It will be blocked by the metal fitting 33. As described above, the attachment structure of the compressor has the locking portion 28 and the pillar portion 29.
By integrally forming the bottom frame 26 with the bottom frame 26, the compressor 21 can be easily attached even if the bottom frame 26 is made of synthetic resin, and the compressor 21 is locked by the locking portion 28 only in the vertical direction. By doing so, no force is applied in the horizontal direction to prevent damage due to transportation or dropping.

[0004]

However, in the conventional compressor mounting structure described above, the vibration-proof spring 34 is provided on the bottom frame 26.
Since the compressor 21 is mounted via the, the four sets of the vibration-proof springs 34 and the upper and lower spring bearings are required for stable mounting, which increases the man-hours for mounting work, and thus mounting the compressor 21. There is a drawback that the efficiency of assembling the outdoor air conditioner does not increase. Further, since the four pillar portions 29 and the vertical and horizontal guides 30 and 31 on which the vibration-proof springs 34 are fitted are projectingly provided on the bottom frame 26, it is difficult to apply a soundproof material to these portions, and the compressor 21 is It has the drawback that it cannot be completely soundproofed. This drawback is particularly problematic in a ceiling-suspended outdoor air conditioner or the like because noise from the compressor is transmitted downward. Further, since the compressor 21 is supported by the bottom frame 26 via the four soundproof springs 34, the force due to the vibration of the compressor is 4 as compared with the case where the entire bottom portion of the compressor is supported by the elastic member. Concentrate on the place, bottom frame 26 made of synthetic resin
Is likely to be destroyed.

Therefore, an object of the present invention is to support the entire bottom part of the compressor on the bottom frame via a vibration-proof rubber member, thereby enhancing the soundproofing effect of the compressor, and at the same time, to prevent the bottom frame from being damaged by the resin. It is to provide a compressor mounting structure that can be made into a new type and can significantly reduce the number of work steps for mounting and removing the compressor.

Further, a convex portion 2b projecting upward is formed in the central portion of the mounting leg portion 2 which is in contact with the compressor 1, while the bottom surface of the vibration-proof rubber body 4 has two grooves penetrating in the longitudinal direction. 4b, 4b are formed.
The projections 5 at the four corners of the vibration-proof rubber body 4 are composed of a small-diameter lower portion 5a which fits exactly into the fitting hole 3 of the mounting leg portion 2 and a large-diameter upper portion 5b which projects above the fitting hole 3. The positioning ribs 7 of the bottom frame 6 are provided with a pair of cylindrical screwing protrusions 9, so as to circumscribe the ribs 7 on the line connecting the protrusions 5, 5 facing in the short side direction of the vibration-proof rubber body 4. 9 is integrally formed.
And, by the intermediate portion 10a of the two fasteners 10,
The protrusions 5, 5 protruding from the fitting hole 3 of the mounting leg portion 2 are pressed from above, and screws (not shown) inserted into the holes 11, 11 of both end portions 10b, 10b bent upward in an L-shape are used as described above. The fastener 10 is fixed to the bottom frame 6 by being screwed into the screwing projections 9, 9. The height of the convex portion 2b of the mounting leg portion 2 is lower than the height of the large-diameter upper portion 5b of the protrusion 5 protruding from the fitting hole 3, and the positional relationship between the mounting leg portion 2 and the compressor 1 is The pressing of the projections 5, 5 by the 10, 10 is not hindered.

With the above-described mounting structure, the compressor is mounted on the bottom frame as follows, and has the following operation. The anti-vibration rubber body 4 is fitted into the rectangular positioning rib 7 integrally formed on the bottom frame 6 made of synthetic resin, and the projections 5 at the four corners of the anti-vibration rubber body 4 are spread over the entire bottom surface of the compressor 1. The fitting holes 3 at the four corners of the plate-like mounting leg portion 2 fixed to the above are fitted into the cutout inner edges 4a, 4a of the vibration-proof rubber body 4,
The cut-and-raised parts 8 and 8 of the mounting leg portion 2 are externally fitted to the compressor 1

Since the cut-and-raised parts 8 and 8 which are fitted onto the a and 4a are provided, the vibration of the compressor 1 can be further absorbed due to the increase in the deformability of the vibration-proof rubber body 4, and the vibration in the direction orthogonal to the cut-and-raised parts can be further suppressed. As a result, the attachment leg 2 is also prevented from coming off from the anti-vibration rubber body 4. Further, in the above-described embodiment, as described in claim 4, each protrusion 5 of the prevention rubber body 4 which is fitted into the fitting hole 3 of the mounting leg portion 2 of the compressor 1 is pressed from above by the stopper 10. The fastener 10 is fixed to the two pairs of screw stopper projections 9 provided on the positioning ribs 7 of the bottom frame 6 by the screws inserted into the holes 11 near both ends, so that the mounting leg portion 2 is prevented from the rubber body. It is surely prevented from coming off from 4.

Further, in the above embodiment, since the central portion of the mounting leg portion 2 welded to the compressor 1 is the convex portion 2b which does not protrude and contact downward, the vibration of the compressor 1 is directly vibrated rubber body. 4 and the bottom frame 6 have the advantage that the vibration damping effect is improved. Further, since the large-diameter upper portion 5b of the protrusion 5 of the anti-vibration rubber body 4 covers the small-diameter fitting hole 3 of the mounting leg portion 2, even if the stopper 10 is not provided, the anti-vibration of the mounting leg portion 2 is prevented.
