Abstract

PURPOSE:To improve the moldability and strength of a partition and inner box and the moldability of a stopper by extending a partition which is formed integrally with an inner box and devices the interior of a refrigerator into a plurality of chambers, forwardly from a rear wall to the middle part thereof and providing a stopper for a shelf on the front wall part of the partition. CONSTITUTION:In an outer box 1 forming the exterior of the body of a refrigerator an inner box 2 is disposed spaced a predetermined interval from the outer box. In the box 2 a partition 5 which divides the interior of the refrigerator into a plurality of refrigeration chambers 3, 4 is formed integrally with the inner box. A plurality of rails 6 on which a shelf is mounted are formed on the partition 5, in which the partition 5 is extended forwardly from the rear wall of the box 2 to the middle part of said box and protrusions 15, as stoppers, are formed on partitioning front walls 7 forming the front part of the partition 5. As a result, the amount of extension of the partition 5 can be restrained as compared to the conventional case, thereby facilitating the molding of the partition 5 and inner box 2 and improving the strength, and further making the formation of the stoppers for the walls 7 easier.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to improving the moldability of an inner box of a refrigerator and to the structure of a stopper part of a shelf.

0002

[Prior art] Figures 8 to 10 are, for example,
This figure shows a conventional refrigerator inner box partition structure and shelf stopper structure shown in Publication No. 38. In the figure, 1 is an outer box that forms the outside of the refrigerator main body, and 2 is an inner box that is assembled with a gap inside the outer box 1 and is connected to a freezer compartment 3, a refrigerator 4, and a partition wall 5 that partitions both compartments. It is an inner box made of synthetic resin that bulges forward from the wall and is integrally formed by vacuum forming. A synthetic resin partition wall 7 is formed on the front side of the inner box partition wall 5, and is used to house a dew prevention pipe and fix a partition plate 9 made of an iron plate or the like that comes into contact with a door packing (not shown). are doing.

A rail portion 6 for mounting and supporting the shelves of the freezer compartment 3 and refrigerator compartment 4 is integrally formed on the wall surface of the inner box 2, and a stopper with a mechanism to stop the shelf 12 when it is pulled out is provided on the front surface. 14 is fixed to the wall surface of the inner box 2 with screws 13 or the like.

0004

[Problem to be solved by the invention] Conventional refrigerator inner box 2
Since the inner partition is constructed as described above, it is difficult to mold the partition wall 5 of the inner box 2 so that it bulges out to the front side, and the inner box wall also becomes thin, and the shelf rails and wall surfaces are not strong enough. There wasn't. Furthermore, there are problems in terms of workability and cost when fixing the stopper 14 to the inner box 2, and in particular, the width of the portion that bulges out from the back side is narrow, causing problems in workability.

This invention was made to solve the above-mentioned problems, and aims to improve the formability of the partition part of the inner box and the ease of attaching a stopper to the partition wall part where workability is poor. shall be.

[0006]

[Means for solving the problem] Claim 1 of this invention
In this refrigerator, a partition wall that partitions the inside of the refrigerator into each chamber is integrally formed with the inner box, and the partition wall extends forward from the back wall to the middle part.

According to a second aspect of the present invention, there is provided a refrigerator in which a partition wall that partitions the inside of the refrigerator into each room is formed integrally with the inner box, and a shelf is mounted on a rail portion of the partition wall. A stopper portion of the shelf was provided on the front wall of the partition forming the front portion of the shelf.

[0008]

[Function] In the refrigerator according to claim 1 of the present invention, the height of the partition wall of the inner box is reduced, so that the moldability of the inner box is improved.

[0009] In the refrigerator according to claim 2 of the present invention, since the stopper portion of the shelf is formed on the front wall of the partition, installation is facilitated.

【Example】

Example 1. Embodiment 1 of the present invention will be described below with reference to FIGS. 1 to 3. In the figure, 1 is an outer box that forms the outside of the refrigerator body, 2 is an inner box that is assembled with a gap inside the outer box 1, and includes a freezer compartment 3, a freezer compartment 4, and a partition wall 5 that partitions the two compartments. This is an inner box made of synthetic resin, which is integrally formed by vacuum forming or the like, and bulges forward from the back wall to the middle part. The freezer compartment 3 has an inner box adjusted to a temperature of about -20°C to store frozen food, and the refrigerator compartment 4 has an inner box adjusted to a temperature of 3 to 8°C to store refrigerated food. In each chamber, a rail portion 6 on which a shelf for placing food is placed is integrally formed on the wall surface of the inner box. Further, a plurality of holes 8 are formed in the front surface of the partition wall 5. A front partition wall 7 made of synthetic resin is formed on the front surface of the partition wall 5 and is open on the side that contacts the inner box 2 . Also, when injecting the insulation material, use the injection port 10 on the back side of the outer box 1.
A more rigid urethane foam or other heat insulating material is injected, and the heat insulating material filled in the inner partition wall is further filled into the partition front wall 7 through the front wall hole 8.

Example 2. In addition, in the above embodiment, FIG.
, 5, a rib 11 parallel to the front side of the inner box partition wall is formed on the opening side of the partition front wall 7 and is brought into contact with the front side of the inner box partition wall, thereby ensuring a sealing structure for the heat insulating material. becomes.

Example 3. Next, Embodiment 3 of this invention is shown in FIG.
I will explain about it. A convex portion 15 of a stopper portion is integrally formed on the partition front wall 8, and the amount of the drawer that can be pulled out toward the front of the shelf placed on the rail portion 6 is determined by the position of the convex portion 15 of the stopper portion. Regulated.

Example 4. In the third embodiment described above, by forming the fastening parts 16 on the left and right sides of the partition front wall 7 at positions opposing the stopper protrusion 15 as shown in FIG. It is possible to make it a thing.

[0014]

[Effects of the Invention] The present invention provides the following effects. The refrigerator according to claim 1 is a refrigerator in which a partition wall that partitions the inside of the refrigerator into each chamber is formed integrally with the inner box, and the partition wall is configured to extend forward from the back wall to the middle part, so that the inner box Improved moldability.

[0015] According to a second aspect of the present invention, there is provided a refrigerator in which a partition wall that partitions the inside of the refrigerator into each room is formed integrally with the inner box, and a shelf is mounted on the rail portion of the partition wall, wherein the front part of the partition wall is Since the shelf stopper portion is provided on the front wall of the partition to be formed, the shelf stopper portion can be easily formed.
