[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator in which an assembling space portion is formed between a heat insulating partition wall for partitioning a storage compartment and a refrigerator body, and a cooler is arranged in the assembling space portion.

[0002]

2. Description of the Related Art In a refrigerator, the inside of the refrigerator is protected by a heat insulation partition wall.
There is a structure in which the lower part is divided into a freezer compartment and the upper part is a refrigerating compartment (so-called bottom freezer type). In the case of this configuration, a compressor or the like located in the lower rear part of the freezer compartment becomes an obstacle, so an assembly space is formed between the heat insulation partition wall and the refrigerator body, and a cooler is arranged in this assembly space. is doing.

[0003]

In the above refrigerator, as described in Japanese Patent Application Laid-Open No. 8-247638, a heat insulating partition wall is divided into front and rear, and a front partition wall is attached to the refrigerator main body. There is a configuration in which after the foaming of the heat insulating material, the cooler is assembled using the assembly space portion where the rear partition wall is removed. In the case of this configuration, after the cooler is assembled, the following work is performed in sequence. A cooler cover is inserted into the assembly space to cover the cooler from the front. The partition wall on the rear side is assembled in the refrigerator, and the partition space on the rear side closes the assembly space from the refrigerating compartment side.

However, in the case of the above-mentioned conventional structure, since the rear partition wall is assembled after foaming the refrigerator main body, the sealability between the rear partition wall and the refrigerator main body is poor, and the freezer compartment and the refrigerating compartment are sealed. The sex was low. Moreover, when assembling the rear partition wall, the assembly accuracy of the partition wall varies due to the foaming accuracy of the refrigerator body, and a gap is created between the rear partition wall and the cooler cover. There was a risk that air would leak from this gap. For this reason, air is not efficiently supplied to the cooler, and the generation efficiency of cold air is reduced,
It was necessary to assemble a cooler cover separately or to enlarge the cooler cover to close the gap.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a refrigerator capable of enhancing the sealing property between the refrigerator body and the heat insulating partition wall and the efficiency of generating cold air.

Since it is positioned in the front-rear direction by g, it is possible to prevent the cooler 23 from being displaced in the front-rear direction and preventing the cool air passage from being secured. Moreover, since the sealing material 18 of the evaporation cover 17 is brought into contact with the rib 9g, the contact area between the sealing surfaces is increased. At the same time, the forward elastic force of the rib 9g increases the contact pressure between the seal material 18 and the rib 9g, so that the sealing property between the evaporation cover 17 and the heat insulating partition wall 9 is further improved as a whole.

In the first to third embodiments described above, the recess 9d is formed in the heat insulating partition wall 9 and the right flange portion 17a of the evaporation cover 17 is inserted into the recess 9d, but the present invention is not limited to this.

A long rib 9i may be integrally formed with the convex portion 9h.

In this structure, the cooler 23 is positioned in the front-rear direction by the rib 9i, so that the cooler 23 is prevented from being displaced in the front-rear direction and the cold air passage cannot be secured. Moreover, since the sealing material 18 of the evaporation cover 17 is in contact with the ribs 9i, the contact area between the sealing surfaces is increased, and the contact pressure between the sealing surfaces is increased by the elastic force of the ribs 9i. The sealing property between the evaporation cover 17 and the heat insulating partition wall 9 is further improved. Further, the width of the convex portion 9i in the left-right direction is reduced, and a space can be provided in the heat insulating partition wall 9, so that the opening area of the return duct 9e is increased.

In the first to fourth embodiments described above, the sealing material 18 is attached in advance to the evaporation cover 17, but the present invention is not limited to this. For example, the sealing material 18 is attached in advance to the heat insulation partition wall 9. The sealing material 18 is attached to the cover 1 when the cover 17 is inserted into the assembly space 16.
7 may be contacted. Alternatively, the sealing material 18 may be attached in advance to the heat insulating partition wall 9 and the evaker 17, and the sealing materials 18 may be brought into contact with each other when the evaluation cover 17 is inserted into the assembly space 16.

Further, in the above-mentioned first to fourth embodiments,
The configuration in which the damper unit 11 is attached to the evaporator cover 17 is assembled at once, but the configuration is not limited to this. For example, the evaporator cover 17 to which the fan device 20 is attached and the damper unit 11 are separately assembled. You may do it.
