Description

[Detailed description of the invention] [Field of application of the invention] The present invention relates to a refrigerator.

[Background of the invention]

The structural and performance problems of conventional refrigerators of this type are comparable to conventional refrigerators in which the partition wall that separates the freezer and refrigerator compartments is not integrally formed with the inner box. There was the following problem.

(1) Insert into the integrally molded neutral 9J section before foaming on site, the partitions are formed with cold air ventilation channels, defrost water drainage channels for the cooler, etc., and are moved by cutting heat or foaming pressure during foaming. (2) If the partition heat moves as described above, it will be difficult to dispose of the defrosting water from the cooling 1j+ installed at the back of the freezer compartment. The relationship between the cooling) gauge and the ventilation path is also out of order, resulting in an IM problem that causes variations in cooling performance.

(3) Some of the parts attached to the front of the cooler, such as the cold air handle and cold air direction plate, are different from the conventional Refrigerated No. 1 because the upper plate of the partition wall is molded by injection molding, etc. Protrusions or recesses can be molded as one piece, whereas an inner box that is integrally molded with internal partitions is molded from a single sheet by vacuum forming, etc., so it is very difficult to mold protrusions or recesses. However, when installing these parts, separate parts are required and a lot of work is required.

The present invention has been made to improve these problems. That is, the partition wall that separates the freezer compartment and the refrigerator compartment is formed integrally with the inner box that forms the freezer compartment and the refrigerator compartment, and the cooler is installed astride the back wall and the partition wall of the freezer compartment. The lower end of the cooler is fixed using a gutter that receives defrosting water, and a cold air ventilation path is formed using the gutter as a reference.
