Hereinafter, the configuration of the present invention will be described in detail with reference to the accompanying drawings.

3 is a cross-sectional view showing a dustproof device for a compressor according to the present invention, Figure 4 is a cross-sectional view showing another example of the fixing bolt of the dustproof device for a compressor according to the present invention.

As shown in FIG. 3, the vibration isolator for the compressor according to the present invention is provided to reduce vibration generated in the compressor 130 installed on the base plate 120 of the machine room 110 of the refrigerator 100. The compressor 130 is fixedly mounted on the mount assembly 10 in which a plurality of components are assembled.

The mount assembly 10 is integrally installed under the compressor 130 and is installed between the mount bracket 140 and the base plate 120 supporting the compressor 130.

Through-holes 141 are formed in each corner region of the mount bracket 140 through the bracket surface, and the upper dustproof member 11 having the shaft holes 140a formed along the central axis is formed in the through-holes 141. Are combined.

In the circumferential surface of the upper dustproof member 11, fitting jaws 11b are formed on the outer circumferential surface so that the through holes 141 can be fitted, so that the upper dustproof member 11 is easily separated from the mount bracket 140. Will not be.

In addition, a fixing bolt 12 having a washer insertion surface 12a formed thereon passes through the shaft hole 11a of the upper dustproof member 11.

The outer diameter of the fixing bolt 12 is formed small with respect to the shaft hole (11a) of the upper dustproof member 11 is a gap between the shaft hole (11a) and the fixing bolt 12 is generated.

Therefore, the upper dustproof member 11 is spaced apart from each other while sharing the center line with the fixed bolt 12 so that the vibration generated in the compressor 130 is not transmitted to the fixed bolt 12 via the upper dustproof member 11. do.

On the contrary, the vibration transmitted to the upper dustproof member 11 is directly transmitted to the elastic member 14 and the lower dustproof member 13, which will be described later, to be effectively absorbed.

Here, the diameter of the fixing bolt 12 is preferably formed to be 2 ~ 3mm smaller than the inner diameter of the shaft hole (11a) of the upper dustproof member (11).

At this time, as shown in Figure 4, the fixing bolt 12 may be formed in a smaller overall diameter so as to be spaced apart from the shaft hole (11a) of the upper dustproof member 11, the upper dustproof member 11 is inserted In addition, the diameter can be formed small in the corresponding region.

However, the diameter of the lower seating surface 12b of the fixing bolt 12, which is a region into which the lower dustproof member 13 to be described later is inserted, is formed to be approximately equal to the inner diameter of the shaft hole 13a of the lower dustproof member 13. desirable.

Meanwhile, the fixing bolt 12 is inserted into and fixed to the through hole 121 of the base plate 120 of the machine room 110 of the refrigerator 100.

In this case, the fixing bolt 12 is firmly fixed to the through hole 121 so that the fixing bolt 12 can be maintained in an upright state without being easily separated from the through hole 121 of the base plate 120.

In addition, the lower dustproof member 13 is inserted into the lower outer circumferential surface of the fixing bolt 12 on the base plate 120 surface through the shaft hole 13a to firmly support the fixing bolt 12.

In addition, an elastic member 14 including a compression coil spring is interposed between the upper dustproof member 11 and the lower dustproof member 13.

Here, it is obvious that the upper dustproof member 11 and the lower dustproof member 13 are made of a rubber material exhibiting elastic force.

Mount assembly 10 having such a configuration is generated during operation of the refrigerator by allowing the vibration generated in the compressor 130 to be sequentially transmitted to the upper dustproof member 11, the elastic member 14, the lower dustproof member 13. The vibration can be effectively absorbed.

On the other hand, Figure 5 is a cross-sectional view showing a dustproof device for a compressor according to another embodiment of the present invention, Figure 5 will not be described for the same parts as the embodiment of Figure 3 will be described only the different configuration.

Mounting assembly 10 of the anti-vibration device for a compressor according to another embodiment of the present invention is integrally installed in the lower portion of the compressor 130 to support the compressor 130 and the mounting bracket 140 and the base plate 120 It is installed between the and includes an integral dustproof member 15, the shaft hole (15a) is formed in each of the upper and lower.

A fixing bolt 12 having a washer insertion surface 12a is formed to pass through the shaft hole 15a located above the integrated dustproof member 15.

The outer diameter of the fixing bolt 12 is formed small with respect to the shaft hole (15a) located in the upper portion of the integral dust-proof member 15, the play between the upper shaft hole (15a) and the fixing bolt 12 is generated.

On the other hand, the fixing bolt 12 is inserted and fixed in the shaft hole (15a) located below the integrated dustproof member 15 without play.

Therefore, since the integrated dustproof member 15 shares the center line with the fixed bolt 12 and the upper side is spaced apart from each other, the vibration generated from the compressor 130 passes through the integrated dustproof member 15 to the fixed bolt 12. It will not be delivered.

On the contrary, the vibration transmitted to the integrated dustproof member 15 can be absorbed by itself.

Hereinafter, the present invention will be described in more detail based on the vibration and noise related experimental examples of the dustproof device for a compressor according to the present invention configured as described above and the dustproof device for a compressor according to the prior art. It is not limited to.

Figure pat00001

Under the same experimental conditions, the vibration test of the 500-liter refrigerator, it can be seen that there is an excellent improvement effect in various locations of the refrigerator to which the dustproof device for compressor according to the present invention is applied.

As shown in Table 1, the vibration isolator for compressor according to the present invention, compared to the conventional vibration isolator for compressors, it can be seen that the vibration at the center of the upper right side of the freezer compartment right side and the refrigerating chamber door 45 degrees significantly reduced. In addition, the vibration in the center of the freezer door can be seen to be reduced more than twice.

Figure pat00002

Under the same experimental conditions, the noise test results of the refrigerator, it can be seen that there is an excellent improvement effect at various locations of the refrigerator to which the dustproof device for a compressor according to the present invention is applied.

6 is a graph illustrating noise measurement data of a dustproof device for a compressor according to the related art and the present invention, as shown in Table 2 and FIG. As a result of experiments by installing a noise measuring device 100mm from the center of the 1/2 point, it can be seen that the vibration isolator for the compressor according to the present invention, the noise is significantly reduced compared to the compressor isolator according to the prior art.

Therefore, the refrigerator equipped with a vibration isolator for the compressor according to the present invention, since the vibration generated in the compressor is not directly transmitted to the base plate by the fixing bolt 12, it is possible to significantly reduce the generation of vibration noise.
