Description

[Detailed description of the invention] The present invention relates to a support device for a compressor, and has a structure that can sufficiently withstand the vibrations of the compressor by providing a support pin with a plurality of overhanging pieces that extend radially and have approximately uniform wall thickness. In addition, by integrally molding the support pins and the bottom plate of the unit from synthetic resin or the like, the purpose is to reduce the cost of the unit and improve the ease of assembly.

Conventionally, as a support device for a compressor, a bolt is erected and fixed to the bottom plate, and the legs of the compressor are held by the bolt via an elastic body. Therefore, it is necessary to fix the bolts to the bottom plate, which not only impairs the ease of assembly, but also increases costs due to the bolts.

In addition, when a substantially cylindrical support pin corresponding to this bolt is molded integrally with the bottom plate using synthetic resin, the thickness of the bottom plate near the base of the support pin becomes thicker, and after the bottom plate is molded, the bottom plate in this area becomes thicker. A large sink mark occurred on the back side of the compressor, causing the support pin to tilt and potentially making it impossible to support the compressor.

Further, when the support pin is formed into a substantially cylindrical shape, the center of the pin is difficult to cool down after the support pin is molded, and distortion remains in the support pin, resulting in poor strength and the possibility that it will not be able to withstand the vibrations of the compressor.

In view of the above-mentioned drawbacks, this project has a support pin that supports the compressor integrally molded with the unit bottom plate, thereby reducing costs and improving assembly workability. , the compressor can be reliably supported by reducing sink marks that occur immediately after integral molding in the bottom plate manufacturing process while maintaining the same strength as conventional bolts.

An embodiment of the present invention will be described below with reference to the drawings.
In Figure 1, 1 is an integrated air conditioner installed in a window, etc. As shown in Figure 2, the bottom plate 2 is made of synthetic resin.
A compressor 4, a condenser 5, an evaporator 6, etc. are built into the main body, which is constituted by an exterior body 3 surrounding the bottom plate.

7 is a partition plate that divides the main body into an indoor chamber 8 in which the evaporator 3 is disposed and an outdoor chamber 9 in which the condenser 5 is disposed; 10 and 11 are the indoor chamber 8 and the outdoor chamber 9, respectively.
With the vertically arranged blower, as shown by the solid line arrow in Figure 3, the indoor air sucked in from the indoor suction port 12 by the operation of the indoor blower 10 is cooled by the evaporator 6, and then discharged from the indoor discharge port 13, and is then discharged from the indoor air outlet 13. The condenser 5 is cooled with outdoor air taken in through the outdoor suction port 14 by the operation of the blower 8, and the cooled air is discharged from the outdoor discharge port 15. Reference numeral 16 denotes a dew pan disposed at the bottom of the evaporator 6, and is adapted to receive dew water dripping from the evaporator 6. Reference numeral 17 denotes an electrical box containing electrical components for controlling the operation of this air conditioner.

As shown in FIG. 4, the compressor 4 described above has a leg piece 18 fixed to its lower part, and an upper elastic body 20 is fitted into a hole 19 of the leg piece 18. A support pin 21 is integrally molded with the bottom plate 2 and stands upwardly, and is inserted into the fitting hole 22 of the upper elastic body. This support pin 21 protrudes beyond the hole 19 of the leg piece 18,
When the leg piece 18 moves in the horizontal direction, the support pin 21 comes into contact with the inner wall of the fitting hole 22 of the upper elastic body 20 to restrict the movement of the leg piece. As shown in FIG. 5, this support pin 21 is provided with recesses 23 at four locations on its outer peripheral surface, and has a substantially cross-shaped cross section so that the wall thicknesses a of the four projecting pieces 24 are substantially the same. 25 is a lower elastic body inserted into this support pin 21, and 26 is this lower elastic body and the upper elastic body 20.
It is a coil spring held between.

Support pin 2 made of synthetic resin as described above
Since the wall thickness dimension a of each overhanging piece 24 of No. 1 is made substantially uniform, the support pin 21 is quickly cooled down to the center of the pin after molding, making it difficult for distortion to remain.
Further, the core portion of the base of the support pin 21 is made thinner due to the formation of the overhanging piece 24, and sink marks are less likely to occur on the back surface of the bottom plate 2, so that the support pin 21 is held in an upright state. Furthermore, since the plurality of overhanging pieces 24 are formed to spread radially, it is possible to maintain the same strength as a conventional bolt even against vibrations of the compressor 4. Of course, since this support pin 21 is integrally molded with the unit bottom plate 2, the workability of assembling this support device is excellent and costs can be reduced.

Note that the support pin 21 is not limited to a cross-shaped cross section as shown in FIG. 5, but may also have support pins 21', 21 with projecting pieces 24', 24'' extending radially as shown in FIGS. 6 and 7. ``It goes without saying that it is fine.

As detailed above, the present invention includes an elastic body attached to the leg of the compressor, a support pin inserted into the fitting hole of the elastic body, and a unit bottom plate integrally formed with the pin. It is possible to reduce costs and improve assembly workability.

This support pin has a plurality of vertically extending overhang pieces that extend radially toward the outer circumference, making it easier to quickly cool down to the center of the pin after the support pin is molded, making it difficult for distortion to remain in the support pin. The strength of the lever support pin can be improved.
In addition, the core of the base of this support pin becomes thinner due to the formation of the overhanging piece, making it difficult for sink marks to occur on the back side of the bottom plate near this base, so this support pin should be installed perpendicular to the bottom plate. I can do it. Since the height of this support pin is set to a dimension that restricts the horizontal movement of the leg piece to which the elastic body is attached, the horizontal movement of the compressor can be received by the support pin via the elastic body. . Further, since a plurality of projecting pieces are provided on the outer periphery of this support pin, the above-mentioned force can be reliably stopped by this support pin.
