Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a refrigerator in which a plurality of storage compartments, such as a freezer compartment and a refrigerator compartment, are partitioned by partitions and each compartment is provided with a door.

BACKGROUND ART A conventional example will be explained with reference to FIGS. In the figure, a refrigerator main body 1 has a freezer compartment 2 and a refrigerator compartment 3.
It is comprised of an outer box 4, an inner box 6, a heat insulating material 6 filled between these two boxes 4 and 6, a partition 7 that partitions the inside of the inner box 5 into a freezing compartment 2 and a refrigerating compartment 3. The partition part is integrally molded with the inner box 5, and a partition front plate 9 is provided in the front part of the partition front wall 8 at the frontmost part so as to cover the partition part front wall 8. This partition front plate 9 is stepped at both ends, and the stepped portions 9a are engaged with the outer box flange 4a, and the outer box flange 4a and the partition front plate 9 are fixed so as to be substantially on the same plane. There is. Reference numeral 1o denotes a door, which is attached to cover the freezer compartment 2 and the refrigerator compartment 3, respectively.
It is composed of a heat insulating material 12 filled inside, a door back plate 13, a gasket 14 held between the door plate 11 and the door back plate 13, and the like. This gasket 14 is made of soft vinyl chloride or the like, and its top 14a abuts against the outer box flange 4a and the partition front plate 9 to seal them.

In the above configuration, the door 10 has a hinge point 16
It opens and closes by rotating around the freezer compartment 2,
The food and the like stored in the refrigerator compartment 3 are taken out and put in there. At this time, the gasket 14 expands and contracts, and each time the gasket top 14'a comes into contact with the outer box flange 4a1 and the partition front plate 9, the cold air in the freezer compartment 2 and refrigerator compartment 3 does not flow out to the outside. It is sealed tightly.

Problems to be Solved by the Invention However, in such a configuration, the expansion and contraction of the gasket 14 is insufficient, the partition front plate 9 is particularly dented, or the partition between the partition front plate 9 and the inner box 6 is damaged. Due to various reasons such as the movement of the partition front plate 9 due to the space 1e between the gasket top 14a and the partition front wall 8, there is a gap between the gasket top 14a and the partition front plate 9 from both ends of the partition front plate 9 to the center. A gap 17 is created that gradually increases toward the bottom, and cold air in the freezer compartment 2 or refrigerator compartment 3 flows out from this gap 17, and the partition front plate 9 is cooled.
Condensation may form on the surface and energy loss may occur due to excessive cooling operation. In order to prevent this phenomenon, a magnet has been inserted into the gasket top bag 18 and its magnetic force is used to attract it to the partition front plate 9. However, for this purpose, the partition front plate 9 is not necessary. It is necessary to select a magnetic material as the material, such as a coated steel plate, which makes it difficult to avoid heat leakage due to heat conduction, complicates the structure, and reduces cost, cooling efficiency, and energy saving. There were some problems in terms of aspects.

The present invention solves the above-mentioned conventional problems, and
The purpose is to prevent condensation and energy loss in front of the partition and on the plate surface due to leakage of cold air, or to prevent the structure of the front of the partition from becoming complicated.

Means for Solving the Problems In order to solve the above problems, the present invention eliminates the partition front plate and forms the partition front wall of the inner box into a smoothly convex shape from both ends toward the center. It is something to do.

Effects of the present invention With the above-described configuration, the rigidity of the front wall of the partition is increased to prevent dent-like deformation and movement, and the shape of the front wall of the partition conforms to the expansion and contraction characteristics of the gasket, so that the top of the gasket and It is possible to eliminate gaps between the front wall of the partition, simplify the structure, and prevent cold air from leaking.

EXAMPLES Hereinafter, examples of the present invention will be described with reference to FIGS. 1 to 4. It should be noted that the same configurations as those of the prior art will be given the same reference numerals, detailed explanations thereof will be omitted, and only the different parts will be described.

In the figure, the partition front wall 8 has both ends 8a.

The flange 8b is stepped and formed to have approximately the same height as the outer box flange 4a, and is formed into a smooth convex shape from both ends sa and sb toward the center 8C. - door 10
A gasket 14 fixed in a frame shape around the mounting surface 1
In order to prevent the cross-sectional height A from 4b to the top surface 14ai from becoming small, the corner portion 14c is filled with a foam material 19.

However, the long side portions deform smoothly due to the general characteristic of soft resin extrusion molded products that the cross-sectional height A gradually decreases from the corner portion 14c to the center portion 14d. This gasket 14 has its top surface 14a connected to the outer box flange 4a.

The freezer compartment 2 and the refrigerator compartment 3 are sealed by contacting the partition front wall 8. Further, in the gasket top bag 18, a magnet 21 is inserted and attracted to the horizontal side 2o facing the outer box flange 4a, but the magnet 20 is not inserted into the vertical side 22 facing the partition front wall 8. Not yet. Note that the inside of the partition 7 is completely filled with the heat insulating material 6 up to the front wall 8 of the partition.

In such a configuration, the door 1o rotates around the hinge point 16 to perform opening and closing operations, but the door 10 is attracted to the outer box flange 4a by the magnetism of the magnet 21 inserted into the vertical side 22 of the gasket, and is closed. maintained in the state. That is, the vertical side 22 of the gasket 14 is brought into contact with the entire length by the attraction of the magnet 21 and is sealed. Further, the cross-sectional height A of the gasket horizontal side 22 facing the partition front wall 8 is deformed as it gradually decreases from the corner portion 14c toward the center portion 14C. 8
However, since it is formed into a smooth convex shape from both ends 8b toward the center portion 8C, it is able to abut without any gap and be sealed. Moreover, since the inside of the partition front wall 8 is completely filled with the heat insulating material 6, the rigidity is extremely high, and no concave deformation or movement occurs.

Effects of the Invention As is clear from the above explanation, according to the present invention, the front wall of the partition part that partitions a plurality of storage rooms and the gasket can be brought into reliable contact with each other. The front plate made of aluminum is no longer necessary, the structure of the partition can be made very simple, and there is no possibility of concave deformation or free movement of the front plate of the partition. In addition, since a steel plate with good thermal conductivity is not used, heat leakage from the front wall of the partition can be minimized, and there is no condensation on the surface, so cooling only needs to be done to the areas that need it. Therefore, the cooling efficiency is high and energy can be used effectively. Furthermore, the gasket itself does not require a magnet on the side facing the front wall of the partition. Furthermore, if the inner box is manufactured by vacuum forming ABS resin or the like, the present invention can be easily realized by following the recent technological trend, and it is very easy to realize, and it is also superior in terms of cost, cooling efficiency, and energy saving. It is something that brings about an effect.
