Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator having an ice making room and another storage room arranged side by side between a refrigerator room and a freezer room arranged vertically.

[0002]

In recent years, some refrigerators have, in order from the top, a refrigerator room, an ice making room and a specification switching room arranged side by side, a freezing room, and a vegetable room.

[0003] Generally, the main body of a refrigerator is constituted by accommodating an inner box formed by vacuum molding of plastic in an outer box made of a steel plate, and filling a foam insulating material between the outer box and the inner box. Is done. By the way, when manufacturing the above-described multi-chamber refrigerator, in consideration of manufacturability and cost, each room and a partition section for partitioning each room are integrally formed with the inner box, and the inside of each partition section is also formed. It is preferable to fill the foam insulation material.

However, when an inner box having a large number of chambers as described above is to be vacuum formed, the elongation rate of the ice making chamber and the specification switching chamber, which are adjacent to each other on the left and right, are particularly higher than those of the other parts. Therefore, the thickness of the portion may become extremely thin or tear may occur, which is practically impossible.

For this reason, conventionally, a plurality of heat insulating plates separate from the inner box are used in the ice making room and the specification switching room, and the ice making room and the specification switching room are formed by these heat insulating plates. Like that.

However, when a plurality of heat insulating plates separate from the inner box are used, it is necessary to attach each of the heat insulating plates to the inner box. The number of parts increases, and the cost increases. In addition, the partition part of the part using the heat insulating plate, the partition part is formed integrally with the inner box, and the heat insulation performance and strength are reduced as compared with the configuration in which the inside is filled with foamed heat insulating material. There is a problem.

[0007] The present invention has been made in view of the above circumstances, and an object thereof is to provide a multi-chamber system,
The partition that divides each chamber can be formed as integral with the inner box as possible, and the reduction in manufacturability can be suppressed as much as possible, and the increase in the number of parts can be suppressed. Another object of the present invention is to provide a refrigerator capable of minimizing the heat insulation performance and strength of the partition.

[0008]

In order to achieve the above-mentioned object, according to the present invention, there is provided a refrigerator having a main body having an inner box therein, and a freezer disposed below the refrigerator. And a refrigerator provided with an ice making room and another storage room arranged side by side between the refrigerator compartment and the freezing room, wherein at least the ice making compartment is used to partition the compartments. It is characterized by being formed integrally with the inner box except for between the compartment and the freezer compartment, and filling the interior of each partition with a heat insulating material.

In the refrigerator having such a configuration, since the ice making room and the freezing room may be at the same temperature, a partition between them can be eliminated. Therefore, in the above-described means, at least the partition between the ice making chamber and the freezing compartment is not integrally formed with the inner box, so that another partition can be integrally formed with the inner box. . And the inside of each partition part integrally formed with the inner box can be filled with a foaming heat insulating material by so-called in-situ foaming. Thereby, while forming the multi-chamber in the main body, it is possible to minimize the trouble caused by using the heat insulating plate separate from the inner box.

In this case, the other storage room adjacent to the ice making room is not integrally formed with the inner box, but is inserted through an opening formed in the front surface of the partition around the portion where the other storage room is to be arranged. It is preferable that the storage chamber forming box is disposed, and a heat insulating material is filled between an outer surface of the storage chamber forming box and a partition facing the storage box (the invention of claim 2). With such a configuration, the inner box can be more easily integrally formed.

[0011] In order to achieve the same object as in the first aspect, the invention of the third aspect is directed to a refrigerator having a refrigerating compartment and a freezing compartment disposed below the refrigerating compartment in a body having an inner box therein. And a refrigerator having an ice making room and another storage room arranged side by side between the refrigerator room and the freezing room, and between the ice making room and the refrigerator room, the ice making room and Between the other storage room, and between the other storage room and the freezer compartment, while forming a crank-shaped partition unit integrally with the inner box, filling the inside of the partition unit with a heat insulating material, A heat insulating plate having heat insulating properties is disposed between the refrigerator compartment and another storage compartment.

In such a means, a partition between the ice making room and the freezing room is eliminated as in the case of claim 1,
A crank-shaped partition for partitioning between the ice making room and the refrigerator room, between the ice making room and the other storage room, and between the other storage room and the freezing room is formed integrally with the inner box. Thereby, it becomes possible to form each partition part integrally with the inner box. Then, by forming each partition part integrally with the inner box in this way, the inside of each partition part can be filled with a foaming heat insulating material by so-called in-situ foaming.

In this case, a heat insulating plate is provided between the refrigerator compartment and another storage room. However, the heat storage plate, two sides of the crank-shaped partition part and the inner box are used to form another storage room. Is formed, so that the number of heat insulating plates used separately from the inner box can be reduced as much as possible.
