Description

[Detailed Description of the Invention] (a) Field of the Invention The present invention relates to a mounting device for an electric compressor used as a cooling device for, for example, a refrigerator.

(b) Background FIG. 1 shows, for example, a sectional view of the bottom side of refrigerator A. Reference numeral 1 denotes a vegetable container installed at the lower part of the interior 2 of the refrigerator A. 3 is a machine room formed at the bottom of the refrigerator A, in which an electric compressor C included in the cooling device is housed. The machine room 3 opens to the rear, and devices are installed into the machine room 3 through this opening. The electric compressor C is fixed to a support plate 4, and the support plate 4 has elastic shock-absorbing legs 5' made of rubber or the like.
It is elastically fixed to the base 6 at, for example, four locations around the periphery via. The base 6 is a relatively thick steel plate.
It is molded to double as the legs of the refrigerator A and is fixed to the rear lower part of the machine compartment 3 at the bottom of the refrigerator A. As a result, vibrations generated during operation of the electric compressor C are absorbed by the elastic shock absorbing legs 5' and are not transmitted to other parts, thereby preventing noise.

FIG. 2 shows an enlarged sectional view of a conventional elastic shock absorbing leg 5' portion. Mounting pieces 7 are formed on the base 6 by cutting upward at four locations, and an insertion hole 8 is bored in the upper part of the mounting pieces 7. The elastic buffer leg 5' has a substantially cylindrical shape, and has a horizontal groove 5'a cut slightly inward around the upper part, and an insertion groove 5'b extending vertically through the center.
is formed, and the elastic buffer legs 5' are attached to the support plate 4 by fitting and engaging the engagement holes 4a drilled in the peripheral part of the support plate 4 into the horizontal grooves 5'a, and then inserting the insertion grooves 5'b into the horizontal grooves 5'a. Insert into mounting piece 7. At this time, the mounting piece 7 protrudes so that the insertion hole 8 is located above the elastic buffer leg 5', and the washer 9' is inserted into this mounting piece 7 to be positioned on the upper surface of the elastic buffer leg 5'. ′ to the base 6 through the elastic buffer legs 5′.
By engaging the mounting bar 10 which generates an elastic force to press the elastic buffer leg 5' into the insertion hole 8, the elastic buffer leg 5' is pressed onto the base 6.

(c) Problems with the background art As described above, the support plate 4 is elastically fixed to the base 6, but with this structure, when the support plate 4 is removed, the mounting spring 10 must be removed and the upper This is simple because it only needs to be pulled up, but since the elastic buffer legs 5' are also pulled up at the same time, it is necessary to pull them up at least until the elastic buffer legs 5' are removed from the mounting piece 7. However, in recent years, while there has been a call for increasing the internal storage volume by two volumes, the machine room volume by three is also being reduced.
In the above-mentioned configuration, a gap at least equal to the height of the mounting piece 7 is required between the upper end of the electric compressor C and the ceiling wall of the machine room 3, which reduces the volume of the machine room 3.
This in turn hindered the expansion of the two volumes inside the refrigerator.

(d) Purpose of the invention It is to provide a mounting device for an electric compressor that is easy to remove and requires a small moving space.

(e) Summary of the idea A mounting piece is formed by cutting a part of the base into an upper part with an insertion hole, and an elastic shock-absorbing leg is attached to the upper surface of the mounting piece, which is elastically fitted to the mounting piece so as to be located below the insertion hole. A stepped portion is formed, an engaging hole is bored in the support plate of the electric compressor, and this engaging hole is inserted into a mounting piece to engage the stepped portion, and an elastic presser is further inserted into the mounting piece. After that, a mounting spring is engaged with the insertion hole to press the elastic presser against the support plate, and the support plate is snapped onto the base.

(f) Example of implementation of the invention Figure 3 shows an example of implementation of the invention. Furthermore, the first
Components with the same reference numerals as those in FIG. 1 and FIG. 2 have the same functions, and description thereof will be omitted. 5 is the elastic shock-absorbing leg of the present invention, and the upper surface has a stepped portion 5 with a slight step downward.
The mounting piece 7 is inserted into the insertion groove 5b in advance, which is formed by an insertion groove 5b extending vertically through the center. At this time, the insertion hole 8 is located above the elastic buffer leg 5. Next, step 5
Place the washer 9 on the washer 9, insert the engagement hole 4a of the support plate 4 into the mounting piece 7 from above, and engage it with the stepped portion 5a. As shown in FIG. 3, it protrudes above the support plate 4.
Thereafter, an elastic presser 11 made of synthetic resin or the like is inserted into the mounting piece 7 and engaged with the upper end of the elastic buffer leg 5 protruding from the support plate 4 as shown in FIG. At this time, the elastic presser 11 is in contact with the vicinity of the engagement hole 4a of the support plate 4 and the upper surface of the elastic buffer leg 11, and the support plate 4
The washer 9 has an elastic buffer leg 5 and an elastic presser 11.
It is held in between. After that, attaching spring 1
0 is engaged with the insertion hole 8, and the mounting spring 10 presses the elastic presser 11 in the direction of the support plate 4 by its elastic force, whereby the support plate 4 is elastically attached to the base 6.

Next, when removing the support plate 4 from the base 6 in order to take out the electric compressor C from the machine room 3, first remove the mounting spring 10, pull out the elastic presser 11 from the mounting piece 7, and then pull the support plate 4 upward. At this time, the distance from the stepped portion 5a to the upper end of the mounting piece 7 is sufficient for lifting up the support plate 4. Therefore, the distance between the upper end of the electric compressor C and the ceiling wall of the machine room 3 can be reduced, the volume of the machine room 3 can be reduced accordingly, and the internal volume can be expanded.

(g) Effects According to the present invention, the support plate of the electric compressor can be easily attached to and removed from the base, and maintenance and inspection of the electric compressor can be easily performed. Also, installation,
Since the travel distance required for removal is reduced, the installation space for the electric compressor can be reduced, and dead space can be reduced to achieve effective use of space. Furthermore, since the upper surface of the elastic shock-absorbing leg protrudes beyond the engagement hole, the support plate will not come off from the step, and since the elastic presser contacts the area around the engagement hole and the upper surface of the elastic shock-absorbing leg, it will not be difficult to attach the mounting spring. The support plate is firmly pressed against the elastic shock-absorbing legs to prevent vibrations and damage caused by the vibrations. Furthermore, since the elastic presser engages with the elastic shock-absorbing leg, there will be no positional shift before the mounting spring is attached, and even if there is an error in the distance between the upper end of the elastic shock-absorber leg and the support plate, the elastic presser or elastic This can be absorbed by the elasticity of the buffer legs, and the elastic presser contacts both the support plate and the elastic buffer legs well, achieving stable installation of the electric compressor.
