The present invention relates to a refrigerator, and more particularly, to a fixing structure of a refrigerator compressor to facilitate the fixing operation of the compressor by drilling a fixing portion on one side of the mount to allow the compressor to be fixed to the base plate.

In general, the refrigerator 1 is a device for low-temperature storage of food, and stored in a refrigerator or refrigerated by heat exchange action of the refrigerant depending on the food to be stored.

That is, the cooling operation of the refrigerator 1 is a cycle of compression-condensation-expansion-evaporation of a refrigerant by a cooling engine composed of a compressor 12, a condenser, an evaporator 14 and the like as shown in FIG. ) Is repeatedly performed to cool the inside of the refrigerator 1.

In addition, the refrigerator 1 is largely divided into two parts, the refrigerator compartment 20 and the freezer compartment 30, and if necessary, a vegetable compartment 40 for storing vegetables or fruits is provided inside the refrigerator compartment 20 or separately. It is partitioned into the space provided.

Hereinafter, a structure for fixing the compressor 520 to the base plate 560 will be described with reference to FIGS. 4 and 5.

Figure 4 is an exploded perspective view showing a compressor fixing structure of the refrigerator according to the present invention, Figure 5 is a partial longitudinal cross-sectional view showing a fixing portion constituting the main portion in the fixing structure of the compressor of the refrigerator according to the present invention.

As shown in the figure, the compressor 520 is fixed above the base plate 560, and serves to compress the refrigerant, which is a working fluid, at a high temperature and high pressure. That is, the compressor 520 receives power from the outside to compress the refrigerant and sends the compressed refrigerant to a condenser (not shown).

Therefore, a refrigerant pipe 522 is formed on the left side of the compressor 520 to guide the outflow / inflow of the refrigerant, and the refrigerant pipe 522 is coupled to communicate with the inside of the compressor 520.

Mounts 524 are provided on the left and right sides of the lower surface of the compressor 520. The mount 524 supports the compressor 520 to be mounted to the base plate 560, and is firmly fixed so as not to be separated from the compressor 520.

The front and rear half of the mount 524 is formed with a fixed portion 526, which is a main component of the present invention. The fixing part 526 is to restrain the upper portion of the fixing pin 562 to be described below with an elastic restoring force so that the compressor 520 is not separated from the fixing pin 562, as shown in FIG. 5. Perforated in the up and down direction, the central portion protrudes in the upper direction, is formed integrally with the mount 524.

In more detail, the fixing part 526 is formed by bending four places on the upper surface of the mount 524 in a "+" shape and then pushing up the cut portion upward. Thus, the fixing part 526 has a shape in which the central portion protrudes upward, and the inner side is perforated in the up / down direction.

In addition, the fixing part 526 generates an elastic restoring force by contacting the outer surface of the fixing pin 562 when the fixing pin 562 is inserted upward. To this end, the inner space of the fixing portion 526 is narrower toward the upper direction, it is preferably formed smaller than the outer diameter of the fixing pin 562.

Therefore, if the fixing part 526 is a shape capable of selectively generating elastic restoring force upon interference with the fixing pin 562, any shape can be changed and applied according to the shape of the fixing pin 562.

On the other hand, the upper surface of the base plate 560 is provided with a fixing pin 562 protruding upward. The fixing pins 562 serve to guide the mounting position of the compressor 520, and a plurality of fixing pins 562 are formed in the same shape on the upper surface of the base plate 560, and the plurality of fixing pins 562 are fixing parts. It is formed at a position corresponding to 526.

In addition, a locking groove 564 recessed inward is formed on an upper outer circumferential surface of the fixing pin 562. The locking groove 564 is a place where the fixing part 526 is restrained by the elastic restoring force generated, and the upper end of the fixing part 526 is inserted into the locking groove 564 so that the mount 524 is upward. Flow is limited.

The upper outer circumferential surface of the fixing pin 562 is formed to be inclined. More specifically, the outer circumferential surface of the fixing pin 562 located on the upper side of the locking groove 564 has a substantially conical shape by decreasing the cross-sectional area toward the top.

That is, when the compressor 520 is fixed by the fixing pin 562, the upper end of the fixing pin 562 is first inserted into the fixing part 526, and the inclined upper part and the fixing part of the fixing pin 562 are first inserted. 526 is in contact. In addition, the fixing part 526 is guided along the inclination and spread outward, thereby gradually increasing the elastic restoring force.

Accordingly, the fixing pin 562 can be prevented from being damaged due to a sudden increase in elastic restoring force, and the fixing pin 562 and the fixing part 526 can be easily coupled.

On the other hand, the outer side of the fixing pin 562 is provided with a dustproof port 570. The dustproof sphere 570 is to allow the compressor 520 to absorb and attenuate noise and vibration generated from the compressor 520 when the refrigerant is compressed to high temperature and high pressure, and the inside of the dustproof sphere 570 is up / down. It is perforated to receive the fixing pin 562.

The mount 524 and the compressor 520 are supported upward when the mount 524 is coupled to the dustproof hole 570 fixing pin 562. That is, the upper end and the upper outer circumferential surface of the dustproof opening 570 contact the inner wall surface of the fixing part 526 and the lower end contact the upper surface of the base plate 560.

Therefore, the dustproof opening 570 not only attenuates the vibration and noise of the compressor 520, but also simultaneously supports a part of the load of the compressor 520 and the mount 524.

Hereinafter, a process of fixing the compressor 520 to the base plate 560 using the compressor fixing structure of the refrigerator having the above-described configuration will be described with reference to FIGS. 4 to 7.

Figure 6 is a longitudinal cross-sectional view showing a fixing pin is inserted into the fixing part in the compressor fixing structure of the refrigerator according to the present invention, Figure 7 is a view in which the fixing pin is inserted into the fixing part in the compressor fixing structure of the refrigerator according to the present invention. This is a longitudinal cross-sectional view.

First, the compressor 520 and the anti-vibration opening 570 are inserted into the anti-vibration opening 570 outside the fixing pin 562 in a state in which the compressor 520 and the anti-vibration opening 570 are spaced apart from the upper side of the base plate 560 as shown in FIG. 4.

When the fixing pin 562 is inserted in the center of the dustproof opening 570, the dustproof opening 570 is in contact with the upper surface of the lower base plate 560, and the flow is in any direction except for the upward direction. The upper side of the locking groove 564 is located at the upper side from the upper end of the dustproof opening 570 as shown in Figure 6 is exposed to the outside.

Thereafter, the compressor 520 is fixed to the fixing pin 562. At this time, the mount 524 is coupled to the left / right side of the lower surface of the compressor 520, and the coupling method of the mount 524 and the compressor 520 may be variously applied, such as welding and bolting.

In order to couple the mount 524 to the fixing pin 562, the four fixing parts 526 and the fixing pin 562 are positioned so that they are on the same vertical line, and then the compressor 520 and the mount 524 are placed. It moves downward.

During the movement of the compressor 520 and the mount 524 downward, a fixing pin 562 is inserted into the fixing part 526 as shown in FIG. 6. At this time, the inner wall surface of the fixing part 526 is opened to the outside of the upper outer surface of the fixing pin 562, that is, the inclined outer surface, the elastic restoring force is generated.

In this state, when the compressor 520 is further pressed downward, the upper portion of the fixing pin 562, that is, the upper portion of the locking groove 564, completely passes through the fixing portion 526 upwards. The fixing part 526 has no contact with the fixing pin 562, the interference is terminated.

As the interference between the fixing part 526 and the fixing pin 562 is terminated, the fixing part 526 is retracted inward by the elastic restoring force and restored to its original state, and the fixing part 526 is restored due to the restoration of the fixing part 526. The upper end of the government 526 is located inside the locking groove 564 (see Figure 7).

Through this process, the fixing of the compressor 520 is completed. Since the dustproof opening 570 surrounds the outer circumferential surface of the fixing pin 562, the fixing pin 562 and the mount 524 do not come into contact with the compressor. Noise and vibration generated from the 520 is not transmitted to the fixing pin 562 and the base plate 560.

The scope of the present invention is not limited to the above embodiments, and many other modifications based on the present invention will be possible to those skilled in the art within the above technical scope.

In the embodiment of the present invention, the shape of the anti-vibration opening is applied in the shape of a perforated cylinder, but the length of the anti-vibration opening may be configured to be slightly longer as necessary to regulate the contact between the fixing pin and the locking groove. Of course.

In addition, it is also possible to increase the coupling force by further forming a shape corresponding to the fixing groove on the upper end of the dustproof sphere so that the dustproof sphere and the fixing pin are constrained to each other.

 In the compressor fixing structure of the refrigerator according to the present invention as described in detail above, a fixing portion that performs a role as a stopper is formed integrally on one side of the mount.

Therefore, since a separate part for fixing the compressor is unnecessary, manufacturing cost is reduced, and the number of work steps is significantly reduced.

In addition, since the fixing of the compressor is completed only by applying a downward pressure to the mount and the compressor after adjusting the position of the fixing part and the fixing pin while the dustproof port is inserted into the fixing pin outer surface, there is an advantage of easy assembly.

In addition, since the unfastening of the mount and the fixing pin is prevented, damage to the compressor, which may occur when not fastened, is prevented, thereby improving the reliability of the product.
