仕切部の構造に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator and, more particularly, to the structure of a partition for partitioning the inside of a main body up and down to form a freezer compartment, a refrigerator compartment and the like.

Description of the Related Art In a conventional freezer refrigerator, a freezer compartment, a refrigerator compartment, and a vegetable compartment are respectively formed inside a main body by partition portions from above. In recent freezer refrigerators, the refrigerator compartment should be
In some cases, the freezer compartment and the vegetable compartment are formed separately.

には、十分な強度を確保できないという不具合がある。[0003] Incidentally, such a partition portion is, for example, as disclosed in Japanese Utility Model Publication No. 61-17343.
When forming the main body of the heat insulating structure, after being temporarily fixed to the inner box, the side surface thereof is adhered by the foam heat insulating material filled in the filling space provided between the inner box and the outer box. Some are attached and fixed to the inner box. However, when a separate partition is attached to the inside of the main body, there is a problem that sufficient strength cannot be secured.

And a separate pre-partitioning member is fitted. This pre-partitioning member is for sealing the refrigerator compartment and freezer compartment by contacting a packing provided on the back surface of the door that opens and closes the front opening of the main body.

れるようになる。[0005] Then, the heat insulating member inside the partition part and the inner box having the front end part having the front partition member attached thereto are incorporated into the outer box, and thereafter, into the filling space between the inner box and the outer box. When a foamed heat insulating material, for example, foamed polyurethane is injected, the foamed polyurethane enters the filling space, and the inner and outer boxes are bonded and fixed, and a heat insulating box having a front opening is formed.

The heat insulating member and the pre-partition member are adhered and fixed to the partition part by the foamed polyurethane.

In the case of a flat plate, as shown in FIG.
Between the left and right filling spaces (spaces corresponding to the left and right side walls of the refrigerator) and the hollow portion S2 of the partition portion 3 communicate with each other over the entire length in the front-rear direction. When the foamed polyurethane 4 is filled in this state, the foamed polyurethane 4 in the filling space S1 and the foamed polyurethane 4 in the hollow portion S2 of the partition 3 to which the heat insulating member 5 is bonded are connected.

た。Incidentally, the foamed polyurethane 4 has a property of shrinking when cooled by the cooling operation of the refrigerator, and the shrinkage width is proportional to the length of extension. Therefore, when the filling space S1 and the hollow portion S2 of the partition portion 3 communicate with each other in this way, the extension length of the polyurethane foam existing between the opposing inner wall surfaces of the outer box 1 becomes longer. Therefore, when the polyurethane foam cools, the shrinkage width and the shrinkage force of the foamed polyurethane portion adhered to both inner wall surfaces of the outer box 1 increase, and the shrinking force causes the outer box 1 to be recessed only at the portion corresponding to the partition. There was a problem that it became unsightly.

It has become. Here, by forming such a second gap G2, the polyurethane foam to be filled into the filling space S1 from the inlet described later can flow between the partition portion 3 and the heat insulating member 5, and the polyurethane foam The partition 3 has a heat insulating structure, and the heat insulating member 5 is
It can be adhered to.

The concave portion 12 is formed as shown in FIG. 4. By forming the concave portion 12 in this way, the bonding area between the polyurethane foam and the heat insulating member 5 and the inner box 2 can be increased, and the heat insulation can be more reliably performed. The member 5 can be bonded to the partition 5.

せる程の収縮力は生じない。By dividing the foamed polyurethane filled in the concave portion 12 of the heat insulating member 5 and the foamed polyurethane filled in the filling space S1, the shrinking force of the foamed polyurethane filled in the partition portion 3 is directly reduced. It is difficult to transmit to the inner wall portion of the box 1. Thus, even if the foamed polyurethane cools and shrinks, the shrinkage width can be made very small, so that it is possible to prevent the outer box 1 from being dented by being pulled by the foamed polyurethane in the partition portion. The foamed polyurethane filled in the second gap G2 adheres to the opposing inner wall surfaces of the outer box 1, but the contact area is very small as compared with the extending length, so that the outer box 1 is recessed. It does not produce as much shrinkage.

発泡ポリウレタンを充填する。First, the heat insulating member 5 is inserted into the hollow portion S2 of the partition 3 integrally formed with the inner box 2 from the rear so as to form a second gap G2 between the hollow 3 and the front surface 3b of the partition 3. At the same time, the front end 3a of the partition 3 is formed so as to form a first gap G1 between the pre-partitioning member 10 and the front surface 3b of the partition 3.
To fit. Next, after assembling the inner box 2 with the heat insulating member 5 and the pre-partitioning member 10 attached thereto into the outer box 1, the inner box 2 is filled into the filling space S1 provided between the inner box 2 and the outer box 1. Fill with foamed polyurethane.

The heat insulating member 5 is adhered to the partition 3 by the foamed polyurethane. Further, the foamed polyurethane filled in the second gap G2 also flows into the first gap G1 from the plurality of communication holes 11 formed in the front surface 3b of the partition 3, and the polyurethane foam fills the first gap G1. It becomes evenly distributed.
