The present invention relates to a compressor support assembly, and more particularly, to a compressor support assembly in which the fixing of a compressor can be made more easily. The present invention also relates to a refrigerator including the same.

In general, the refrigerator includes a machine room in which a refrigeration cycle apparatus is installed in a lower portion of the main body. The machine room is generally installed in the lower part of the refrigerator for the center of gravity of the refrigerator, the efficiency of assembly and the vibration reduction.

Compressor of the refrigeration cycle device is a device for sucking and compressing the refrigerant through a suction pipe connected to one side of the case forming a sealed space and then discharges through the discharge pipe connected to the other side of the case, the compression device for compressing the refrigerant inside the case And a driving device for driving the same.

The compressor is generally coupled to the base plate of the machine room of the refrigerator by bolt and nut coupling. Of course, when combined by bolts and nuts, the work time is long and the work is inconvenient due to space constraints.

Therefore, the following compressor support assembly is used for the convenience and shortening of the working time.

First, the fixing plate for fixing the compressor is inserted into a fixing pin protruding from the base plate of the refrigerator machine room. Subsequently, the lid of the fixing pin, which is a separate metal member, is positioned at the top of the fixing pin. Then, the shape of the lid portion of the fixing pin is compression-deformed to be the same as the shape of the upper end of the fixing pin. At this time, since the lid portion of the fixing pin is coupled to wrap around the top of the fixing pin, the fixing plate does not have to be removed from the fixing pin of the base plate of the machine room by removing the compressor.

On the other hand, a shock absorbing member such as rubber is installed between the fixed plate of the compressor and the base plate of the machine room in order to reduce vibration noise when the compressor operates.

However, the conventional compressor support assembly described above has the following problems.

First, in the conventional compressor support assembly, the coupling between the cap of the fixing pin and the fixing pin may be loosened due to the vibration of the compressor or the impact when the refrigerator is transported. That is, the shape of the lid portion of the fixing pin is deformed so that the lid portion of the fixing pin vibrates when the compressor vibrates. Therefore, the lid part, which is a metal member, collides with the fixing pin to generate noise. This noise is recognized by the consumer as a malfunction of the refrigerator to apply for after-sales service and a great burden on the refrigerator manufacturer side.

Second, after the compressor is placed on the fixing pin of the base plate has to be mounted by compressing the lid portion of the fixing pin, which is a separate member, there was a problem that a separate assembly work is required.

The present invention is to solve the above problems, it is an object of the present invention to provide a compressor supporting assembly and a refrigerator including the same by removing the lid of the fixing pin does not generate noise due to the lid.

Another object of the present invention is to provide a compressor support assembly and a refrigerator including the same, which is easy to combine the fixing plate of the compressor.

In order to achieve the above object, the present invention is inserted into a fixed plate fixed to the compressor; And a separation preventing piece provided on the insertion member so as to be elastically deformed so that the fixing plate is inserted into the insertion member and the separation plate is contacted with the fixing plate to prevent its separation.

Here, it is preferable that the separation preventing piece is deformed and deformed upon coupling of the fixing plate and the insertion member, and is deformed and deformed after the coupling is completed, thereby preventing the fixing plate from coming off.

In addition, the separation preventing piece preferably includes a fixing portion fixed to the insertion member, the elastic deformation portion.

Preferably, the deformation part further includes a locking jaw formed at one side.

The locking jaw preferably further includes an inclined portion on the side surface to guide the movement of the fixing plate.

The locking step may further include a flat portion on a bottom surface of the locking jaw to correspond to the upper surface of the fixing plate after completion of the fixing of the fixing plate.

It is preferable that the deformation part is provided in plurality.

It is preferable that a space portion is formed inside the insertion member to form a space in which the deformation portion may be elastically deformed.

In addition, the main body; A compressor for compressing the refrigerant; And an insertion member inserted into a fixed plate to which the compressor is fixed, and a separation prevention piece provided on the insertion member so as to be elastically deformed so that the fixing plate is inserted into the insertion member and then contacted with the fixed plate to prevent its separation. It provides a refrigerator comprising an assembly.

The detachment preventing piece preferably includes a fixing part fixed to the insertion member and an elastically deformable deformation part.

Preferably, the deformation part further includes a locking jaw formed at one side.

It is preferable that the deformation part is provided in plurality.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention that can specifically realize the above object will be described.

Referring to FIG. 1, a machine room 20 is included below the refrigerator body 10. In FIG. 1, a cover covering the machine room 20 is open, and a compressor 30 and a compressor support assembly 50 are provided in the machine room 20.

The refrigerator is. The machine room 20 may be installed on the upper portion of the refrigerator, unlike in FIG. 1. Of course, it would be advantageous to install below the main body 10 when considering the noise reduction and the center of gravity.

The machine room 20 accommodates a refrigerant cycle device and various components of a refrigerator such as the compressor 30. The compressor 30 changes the refrigerant into a gas of high temperature and high pressure. The refrigerant passing through the compressor 30 absorbs external heat while changing to a low pressure gaseous refrigerant while sequentially passing through a condenser, expansion device, and evaporator (not shown). By using this property, the food is kept fresh by keeping the inside of the refrigerator frozen / refrigerated.

Of course, the evaporator (not shown) will be mounted inside the rear of the refrigerator to supply cold air to the refrigerator compartment and the freezer compartment.

The compressor 30 is provided with a fixing plate 32 which allows the compressor 30 to be easily fixed to the refrigerator machine room 20. The fixing plate 32 is provided below the compressor 30 and preferably extends one side thereof. It is preferable that an insertion hole 34 that can be fixed to the machine room 20 is formed at a portion where the fixing plate 32 extends.

The insertion hole 34 is provided with a plurality, the fixing plate 32 may be more firmly coupled to the machine room.

The fixing plate 32 is fixed to the base plate 22 of the refrigerator machine room 20. The base plate 22 of the machine room 20 means the lower surface of the refrigerator machine room, and preferably supports various components installed in the machine room. The base plate 22 preferably has a metal material such as iron.

The base plate 22 is preferably provided with an insertion member 60 to be inserted into the insertion hole 34 of the fixing plate 32. The insertion member 60 may protrude in a direction perpendicular to the base plate 22.

In addition, the insertion member 60 is preferably provided with a plurality of spaced apart. In this case, the compressor 30 can be more firmly coupled. Each insertion member 60 is inserted into a plurality of insertion holes 34, respectively.

A lower portion of the insertion member 60 is provided with a buffer member 90 to support the fixed plate (32). The shock absorbing member 90 has a material such as rubber to absorb shock or vibration. Thus, vibration generated while the compressor 30 compresses the refrigerant will be absorbed by the buffer member 90.

In FIG. 2, the separation prevention piece 70 is deformed and deformed while the fixing plate 32 is inserted into the insertion member 60. 3 illustrates a state in which the fixing plate 32 is inserted into and fixed to the insertion member 60.

The upper portion 62 of the insertion member 60 is preferably smaller in cross-sectional area than the intermediate portion 64 to facilitate insertion into the insertion hole 34 of the fixing plate 32. In addition, the size of the cross-sectional area increases as the lower portion from the upper portion 62 of the insertion member 60 toward the lower side. This will be easy to find the correct insertion position of the fixing plate (32).

Of course, the cross-sectional area of the intermediate portion 64 of the insertion member 60 is preferably equal to or slightly smaller than the cross-sectional area of the insertion hole (34). If the cross-sectional area of the intermediate portion 64 is smaller than the cross-sectional area of the insertion hole 34, vibration occurs in the horizontal or vertical direction when the compressor 30 is driven. This is because noise may be generated between the fixing plate 32 and the insertion member 60 by the vibration.

After the fixing plate 32 is inserted into the insertion member 60, the separation preventing piece 70 is provided to be elastically deformable in the insertion member 60 so that the fixing plate 32 is contacted with the fixing plate 32 to prevent its separation. It is preferable to include.

The separation preventing piece 70 is reduced and deformed when the fixing plate 32 and the insertion member 60 are coupled, and the fixing plate 32 is restored and deformed after the coupling is completed, and the fixing plate 32 is caught and fixed. .

That is, the separation preventing piece 70 is reduced in shape so that the fixing plate 32 is inserted into the middle portion 64 of the insertion member 60 while the fixing plate 32 is coupled. In addition, after the fixing plate 32 is completed to the insertion member 60, the separation preventing piece 70 is restored to its original shape. Therefore, the upper surface of the fixing plate 32 is in surface contact with the lower surface of the separation preventing piece 70 to prevent the removal of the fixing plate 32.

Preferably, the separation preventing piece 70 may include a fixing portion 72 and an elastically deformable deformation portion 74 fixed to the insertion member 60.

The fixing part 72 of the release preventing piece 70 is fixed inside the upper portion 62 of the insertion member 60, so that the release preventing piece 70 is coupled to the insertion member 60. The upper surface of the fixing part 72 and the upper portion 62 of the insertion member 60 may be fixed by a welding method.

In addition, it is also possible to be fixed by bolt coupling. Of course, in the case of using a bolted coupling to form a fastening hole (not shown) in the upper portion 62 of the insertion member 60 and the fixing portion 72 of the separation prevention piece 70 to place each of the fastening holes coaxially Then you will be able to combine the bolts.

The deformable portion 74 provided on one side of the fixing portion 72 of the separation preventing piece 70 is in contact with the separation preventing piece 70 while the fixing plate 32 is inserted into the insertion member 60. In this case, elastic deformation will occur. That is, one end of the deformable part 74 is fixed to the fixing part 72 so that it is difficult to deform, but the other end of the deformable part 74 may be deformed relatively freely.

Of course, the fixing portion 72 and the deformation portion 74 may be formed integrally.

Preferably, the deformation part 74 may further include a locking step 80 formed at one side thereof. The locking jaw 80 is preferably formed to protrude in the radial direction from the outer peripheral surface of the insertion member (60). At this time, by drawing a circle following the outer end of the locking step 80, it becomes larger than the cross section of the insertion hole 34 of the fixing plate (32).

Therefore, even if the cross-sectional area of the insertion hole 34 of the fixing plate 32 is slightly larger than the cross-sectional area of the middle portion 64 of the inserting member 60 due to the catching jaw 80, removal of the fixing plate 32 is possible. Can be prevented.

In addition, the locking step 80 may further include an inclined portion 76 on the side to guide the movement for the coupling of the fixing plate (32). The inclined portion 76 forms an obtuse angle with the side of the deformable portion 74. In addition, the inclined portion 76 may be formed integrally with the locking step 80.

The inclined portion 76 may be provided on the upper surface of the locking jaw 80 so that the deformable portion 74 may be gradually deformed without sudden deformation while the fixing plate 32 is inserted into the insertion member 60. To induce. In addition, the fixing plate 32 is guided by the inclined portion 76 to facilitate assembly.

The locking step 80 may further include a flat portion 78 on the bottom surface of the fixing plate 32 to be in contact with the upper surface of the fixing plate 32 after completion of the coupling.

Since the flat portion 78 of the lower surface has a flat surface, when the fixing plate 32 vibrates up and down, the lower surface of the flat portion 78 and the upper surface of the fixing plate 32 are in surface contact with the fixing plate 32. ) Is prevented from leaving. In addition, unlike the inclined portion 76, the flat portion 78 does not have an inclination, and thus the detachment of the fixing plate 32 can be effectively prevented.

It is preferable that a plurality of deformable portions 74 are provided in the separation preventing piece 70. In addition, the deformable portion 74 is preferably formed to be spaced apart while maintaining the same angle between each. However, in the present embodiment, two deformable portions 74 are provided.

However, in another embodiment of the separation preventing piece 70 shown in FIG. 4, four deformable portions 74 are provided. In addition, three or more deformation parts 74 may be provided. In this case, each of the deformable portions 74 is formed with a locking jaw 80, respectively, it is preferable that each of the locking jaw 80 includes an inclined portion 76 and a flat portion 78.

As shown in FIG. 4, when four deformable parts 74 are formed, each deformable part 74 may be formed at an angle of 90 degrees.

2 and 3, it is preferable that a space portion 66 is formed inside the insertion member 60 to form a space in which the deformation portion 74 may be elastically deformed. That is, one side of the deformation portion 74 is inserted into the space portion 66 while elastically deformed. This is because the deformation part 74 is deformed in the inward direction of the insertion member 60 while the fixing plate 32 is inserted, so that the deformation part 74 is easily deformed.

When the two deformable portions 74 are two, the space portion 66 may have a rectangular parallelepiped space and allow each deformable portion 74 to be drawn in or drawn out from the rectangular parallelepiped space.

In addition, when there are a plurality of deformation parts 74 or more, the space part 66 may have a cylindrical shape. In addition, the space 66 may be formed to have only a space enough to insert the deformation portion 74 of the separation preventing piece 70 without limiting the shape of the internal space.

On the other hand, when the fixing plate 32 passes through the protruding portion at the bottom of the inclined portion 76 of the separation preventing piece 70, the deformation of the deformation portion 74 is the largest. Accordingly, the space 66 should have at least enough space to accommodate the deformed deformation 74 at this time.

Hereinafter, the assembly method and operation of the embodiment according to the present invention described above are as follows.

Referring to FIG. 1, the compressor 30 is accommodated in the machine room 20. In addition, the insertion member 60 is coupled to protrude in the vertical direction to the base plate 22 of the machine room 20. The insertion member 60 may be bolted or screwed with the base plate 22. It is preferable that a plurality of bolts are coupled to one insertion member 60.

In addition, the insertion member 60 is provided with a plurality of spaced apart to support the compressor 30 more stably and firmly.

A description with reference to FIGS. 2 and 3 is as follows.

First, the shock absorbing member 90 is mounted below the insertion member 60. The buffer member 90 prevents noise due to vibration generated at the lower ends of the fixed plate 32 and the insertion member 60 due to the vibration of the driven compressor 30.

Subsequently, the insertion hole 34 of the fixing plate 32 which fixes the lower surface of the compressor 30 is inserted into the insertion member 60 and fixed. A plurality of insertion members 60 are provided, and a plurality of insertion holes 34 are inserted into the plurality of insertion members 60, respectively.

The insertion hole 34 of the fixing plate 32 is positioned on the upper portion 62 of the insertion member 60 and then inserted into the insertion member 60 while lowering the fixing plate 32. At this time, the fixing plate 32 passes through the upper portion 62 of the insertion member 60 to pass through the inclined portion 76 of the locking step 80 of the deformable portion 74.

While the inclined portion 76 and the insertion hole 34 is in surface contact with each other, the deformation size of the deformation portion 74 increases as the insertion hole 34 of the fixed plate 32 goes toward the lower side of the inclined portion 76. Therefore, the deformation size of the deformation portion 74 is also maximized when the insertion hole 34 passes through the maximum protruding portion of the inclined portion 76 of the deformation portion 74.

At this time, the deformation part 74 is deformed while being inserted into the space part 66 formed in the insertion member 60.

After passing through the largest projecting portion in the vertical direction of the inclined portion 76 of the deformable portion 74, the deformable portion 74 is restored again, and the separation preventing piece 70 returns to the shape before deformation. .

In this case, when the combined state, the fixing plate 32 is completely inserted into the insertion member 60, the buffer member 90 is located at the lower end of the fixing plate 32, the buffer portion of the material 90 The lower end of the insertion member 60 is located at the lower end. In addition, the base plate 22 of the machine room in which the insertion member 60 is provided is coupled to the lower end of the insertion member 60.

Due to the combination, power is applied to the refrigerator, and even though the compressor 30 vibrates up and down when the refrigerant circulates, the upper surface of the fixing plate 32 and the flat portion 78 of the separation preventing member 70 are in surface contact. The detachment of the fixing plate 32 is prevented.

In addition, unlike the conventional compressor support assembly, there is no fear of vibration noise due to the lid part because the lid part of the fixing pin does not exist separately.

In addition, due to the driving of the compressor 30, even if the fixed plate 32 vibrates, a part of the vibration is buffered by the buffer member 90.

As shown in FIG. 4, when a plurality of deformable parts 74 are provided, the surface where the upper surface of the fixing plate 32 and the flat portion 78 of the locking step 80 contact with each other when the fixing plate 32 vibrates increases. . Therefore, detachment of the fixing plate 32 can be prevented more efficiently.

The present invention is not limited to the above-described embodiments, and as can be seen in the appended claims, modifications can be made by those skilled in the art to which the invention pertains, and such modifications are within the scope of the present invention.

Referring to the effect of the compressor support assembly and the refrigerator including the same according to the present invention described above are as follows.

First, the compressor support assembly according to the present invention does not require the cap of the fixing pin can eliminate the noise generated between the cap and the fixing pin of the fixing pin.

Second, the compressor may be coupled to the refrigerator by inserting the fixing plate of the compressor into the fixing pin and then inserting the fixing plate of the compressor into the insertion member without going through a separate process of compressing and fixing the lid of the fixing pin.
