Description

Middle divider structure of refrigerator

The present invention relates to an intermediate partition coupling structure of a refrigerator, and more particularly, to an intermediate partition coupling structure of a refrigerator which improves the assembly structure of the intermediate partition to improve assembly workability, improve the structural strength of the intermediate partition, and prevent leakage of the insulation. will be.

In general, a refrigerator having a large capacity is recently preferred according to the improvement of the living standard, and the large capacity refrigerator main body 1 is divided into left and right sides by a middle partition 10 as shown in FIG. 2) and the refrigerating chamber (3). That is, the left side is used as the freezing chamber 2 and the right side is used as the refrigerating chamber 3 with the intermediate partition 10 as a boundary. Then, a door (not shown) is rotatably coupled to the front of the refrigerator body 1 constituting the freezing and refrigerating chambers 2 and 3 by a hinge.

The refrigerator door (not shown), the rubber packing member is attached to each edge of the door to reduce the impact of the contact with the refrigerator main body 1 during the opening and closing process of the door to maintain the airtightness of the refrigerator. Magnetically attached to the inner side of the packing member by the magnetic force, the door is in close contact with the front portion of the front separator 12 to prevent external leakage of cold air.

With reference to Figure 2 showing the structure of the intermediate partition will be described in more detail.

As shown in the drawing, the middle partition 10 includes a front separator 12 positioned at a large front side and a side wall 14 separating a freezer and a refrigerator compartment. The side wall 14 is comprised of the partition 14a which forms the inner wall surface of a freezer compartment and a refrigerating compartment, and the flange part 14b bent vertically at the edge part of the said partition 14a. The flange portion 14b is inserted into the side wall coupling portion 12a of the front separator 12, which will be described later, to form a complete intermediate partition 10.

In addition, the front separator 12 is a portion in contact with the door, the door rotated by the hinge shaft is closely coupled to the front separator 12 to prevent the cool air inside the refrigerator main body to leak to the outside. In addition, the front separator 12 has a side wall coupling portion 12a that is bent inwardly in a "c" shape from the rear, and the side wall coupling portion 12a is symmetrically formed at both sides to form a plen of the side wall 14. A branch portion 14b is inserted into the inner space of the side wall coupling portion 12a to form a complete intermediate partition 10.

The heat dissipation pipe 16 is installed inside the sidewall coupling part 12a of the front separator 12, and the inner partition of the intermediate partition is between the flange portion 14b and the sidewall coupling part 12a of the sidewall 14. The sealing material 18 is attached in order to prevent the leakage of the heat insulating material filled in (15). That is, a gap is generated between the flange portion 14b and the side wall coupling portion 12a of the side wall 14 inserted into the inner space of the side wall coupling portion 12a. In this state, when the heat insulator for heat insulation is filled in the inner box 15 of the intermediate partition 10, the heat insulator penetrates into the gap and leaks to the outside, so that the gap is sealed by attaching a sealing material 18 to prevent this.

However, the following problem occurs in the conventional intermediate partition 10 structure having the above structure.

When assembling the middle partition 10, it is inconvenient for an operator to properly assemble the flange portion 14b of the side wall 14 between the side wall coupling portions 12a, and the coupling force is low so that the middle partition 10 may not be assembled properly. Had a problem. Therefore, a problem arises in that the assembly workability is lowered, and the side wall 14 is separated from the front separator 12 during operation and often detached from the refrigerator main body.

In addition, since a separate sealing material 18 must be installed to prevent leakage of the insulating material filled in the inner wound 15 between the side walls 14 to the outside, the required number of parts increases and this not only causes the efficiency of assembly work deterioration. There is a problem that increases the manufacturing cost.

Therefore, the present invention is devised to solve the above problems, the object of the present invention is to improve the assembly structure of the intermediate partition to facilitate the assembly work, the assembly workability is improved, the structural strength of the central partition is improved, and the thermal insulation solution The central partition of the refrigerator with excellent sealing power is to provide a coupling structure.

In addition, the external leakage of the insulating material is prevented without the need for a separate sealing material to reduce the number of parts is another object to provide a coupling structure of the middle partition of the refrigerator to improve the efficiency of assembly work and to reduce the manufacturing cost.

The present invention according to the above object, the partition wall is formed symmetrically to form the inner wall of the freezer, refrigerating chamber, and the side wall consisting of a flange portion formed in the receiving groove for receiving the heat dissipation pipe and bent in the vertical direction at the end of the partition wall; And a front separator having the flange portion and the inlet end thereof formed narrower than the inner side, the front separator being symmetrically formed on the rear surface thereof, the flange portion of the side wall being coupled to the side wall coupling portion, and the inlet of the front separator being formed in the receiving groove. The intermediate partition of the refrigerator, which is in contact with the outer surface and prevents the release of the side wall and the introduction of the foam liquid into the side wall coupling portion, is achieved by the structure. In addition, a support piece may be further formed at the inlet end of the side wall coupling portion to prevent the side wall from being separated. In addition, the side wall coupling portion is bent a plurality of times at the rear of the front separator to form an inner space in which the flange portion is inserted so that the inlet end is formed narrower than the inner side.

Therefore, when the side wall is coupled to the front separator, there is no shaking, and separation after coupling is prevented. In addition, there is an advantage that no separate sealing material is required to prevent the inflow of the insulating material injected between the side walls.

Next, the middle partition of the refrigerator according to the present invention having the above configuration will be described in more detail with reference to the drawings showing a coupling structure.

3 is a cross-sectional view showing a central partition coupling structure of the refrigerator according to the present invention. As shown, the central partition coupling structure 100 of the refrigerator according to the present invention, the front separator 110 is located in the large front and side walls 120 partitioning the freezer, refrigerator compartment.

First, the front separator 110 will be described. The front separator 110 is a portion in contact with the door, the door rotated by the hinge shaft is closely coupled to the front of the front separator 11 to prevent the cool air inside the refrigerator main body to leak to the outside. And the front separator 110 is bent a plurality of times on both sides of the rear side wall coupling portion 112 is inserted into the flange portion 124 of the side wall 120 to be described later is formed symmetrically.

When the structure of the side wall coupling portion 112 is described, the side wall coupling portion 112 having a predetermined internal space is bent in a predetermined interval vertically at the rear of the front separator, and bent in a double downward slant in the horizontal direction at the bent end. Will form. Therefore, the side wall coupling portion 112 has a shape in which the inlet 112a is somewhat narrow and widens inwardly.

On the other hand, the side wall coupling portion 112 is formed with a support piece 112b that is bent backward at the inclined inlet end portion. The support piece 112b prevents the flange portion 124 of the side wall 120 inserted into the inner space of the side wall coupling portion 112 from being removed by applying a load to the inlet 112a of the side wall coupling portion 112. It plays a role. That is, the support piece 112b exerts a load on the downwardly inclined inlet 112a end, and thus the inlet 112a end is pressed by pressing the outer surface of the receiving groove 124a of the flange portion 124. 124 can be prevented from falling out.

Next, the side wall 120 according to the present invention will be described. The side wall 120 is formed symmetrically, and includes a partition wall 122 and a flange portion 124 that form an inner wall surface of a freezer and refrigerator compartment. That is, the partition wall 122 of the left side wall 120 is the wall surface of the freezer compartment, and the partition wall 122 'of the right side wall 120' forms the wall surface of the refrigerating chamber. Then, the flange portion 124 is bent in the vertical direction at the end of the partition wall 122 is coupled to the side wall coupling portion 112 described above.

On one side of the flange portion 124, a receiving groove 124a having a concave shape is formed so that the heat dissipation pipe 200 in which the completed intermediate partition is installed can be inserted. And, the width of the receiving groove 124a is formed larger than the inlet 112a of the side wall coupling portion 112 described above. Therefore, when the flange portion 1124 is inserted into and coupled to the side wall coupling portion 112, the inlet 112a of the side wall coupling portion 112 is caught by the outer surface of the receiving groove 124a, so that the flange portion 124 is closed. Is prevented from escaping.

Next, the manufacturing process of the intermediate partition 100 according to the present invention configured as described above will be described. First, the flange portion 124 of the left or right side wall 120 to be coupled into the side wall coupling portion 112 of the front separator 110, where the width of the receiving groove 124a of the flange portion 124 Since it is larger than the inlet 112a of the side wall coupling part 112, it cannot be inserted into the side wall coupling part 112 as it is. Therefore, it is combined by forcing. That is, the end of the flange portion 124 of the side wall 120 may be inserted into the inner roll through the inlet 112a of the side wall coupling portion 112, but the width of the receiving groove 124a is the side wall coupling portion 112 It is somewhat larger than the inlet (112a) of the as it can not be inserted into the sidewall coupling portion 112. However, since the receiving groove 124a has a circular shape, it is pushed by applying force from the outside, and the inlet 112a of the side wall coupling portion 112 is elastically deformed by the applying force, so that the receiving groove 124a is formed. It is inserted into the side wall coupling portion 112.

In addition, when the flange portion 124 is fully inserted, the inlet 112a of the side wall coupling portion 112 is caught on the outer surface of the receiving groove 124a, thereby physically applying a force from the outside to the flange portion ( The flange portion 124 does not fall out of the sidewall coupling portion 112 unless the 124 is pulled out.

And, the support piece 112b is formed in the edge part of the said inlet 112a. The support piece 112b applies a load to the end of the inlet 112a, and the inlet 112a end may be tightly adhered to the outer surface of the receiving groove 124a by the load. It can be firmly supported. Therefore, the side wall 120 is firmly coupled to the front separator 110 can be fixed without shaking.

On the other hand, in the state in which the flange portion 124 is fully inserted into the side wall engaging portion 112, as described above, the inlet 112a is caught on the outer surface of the receiving groove 124a, the inlet of the side wall coupling portion 112 There is no clearance at 112a. Therefore, it is not necessary to install a separate sealing agent at the inlet 112a of the side wall coupling portion 112 in order to prevent the foam liquid from seeping as conventionally.

Then, the side wall 120 of one side is coupled to the front separator 110, and the remaining side wall 120 'is also coupled to the front separator 110 in the same manner. As described above, when both side walls 120 and 120 ′ are inserted into and coupled to the side wall coupling portion 112 of the front separator 110, the inlet 112 a of the front separator 110 is a receiving groove of each side wall 120. (124a) The outer surface is pressed and fixed without shaking. Therefore, the side wall 120 is separated or separated from the side wall coupling part 112 even in a transfer process for performing a subsequent work, so that the work can be conveniently performed.

Then, the flange portion 124 is inserted into the side wall coupling portion 112 of the front separator 110 so that the side wall 120 is coupled, and then radiates into the receiving groove 124a of the flange portion 124. Install the pipe 200. When the installation of the heat dissipation pipe 200 is completed, the insulation is injected into the space between the side walls 120. Conventionally, a sealing material is attached between the flange portion 124 and the side wall coupling portion 112 to prevent the heat insulator from flowing into the side wall coupling portion 112. However, in the present invention, the end of the inlet 112 a is the flange portion. Close to the outer surface of the receiving groove 124a of the 124, so that no gap is generated, so that a separate sealing member is not required. Therefore, the number of parts can be reduced compared to the prior art, thereby achieving a reduction in manufacturing cost.

As described above, according to the intermediate partition coupling structure of the refrigerator according to the present invention, the assembling work is easy to improve the assembly workability and the structural strength of the central partition is improved.

In addition, since there is no need for a separate sealing material to prevent the insulator from flowing, there is an advantage that the number of parts can be reduced and thus manufacturing cost can be reduced.
