Abstract

PURPOSE:To prevent a gasket from being exposed to cold air directly by a method wherein left and right doors, supported pivotably through bearings, are provided so as to blockade the opening of an adiabatic box having the opening and a guide section, preventing the invasion of cold air by pivoting a partitioning body by the opening and/or closing of the doors, are provided while a gap between an outer casing and an inner casing is eliminated by the guide sections, in a freezing refrigerator having both sides opening doors. CONSTITUTION:A step at the connecting part of an outer casing 2 and in inner casing 3 is eliminated by guide decorative plates 14. A freezing refrigerator, having excellent cooling efficiency, can be realized by improving the configuration of guide sections to eliminate the gap generated by the step between the outer casing and the inner casing of a freezing refrigerator 1 equipped with a first door 6A and a second door 6B of both sides opening type.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door device for a refrigerator-freezer in which the opening of a heat-insulating box is opened and closed by double doors, and each door is provided with a gasket for sealing on the back side of the door.

0002

2. Description of the Related Art Conventionally, this type of door has been constructed as shown in FIGS. 7 and 8, such as the NR-F40VP1 released in March 1990.

Reference numeral 1 denotes a refrigerator-freezer body, 2 an outer box made of iron plate, 3 an inner box made of synthetic resin, 4 a foam insulation material filled between the outer box 2 and the inner box 3, and 5 5A is an opening of the insulation box 5, and 6A and 6B are two panels rotatably supported by upper and lower hinges 7A and 7B provided at the top and bottom of the left and right edges of the insulation box 5. Kannon opening type door, 8 is door 6
A and 6B are located on the non-pivot side of the opening 5A of the heat insulating box 5, and the guide portions are formed to protrude upward and downward to face each other, and the front surface of the guide portion 8 is flat and open. It is almost on the same level as 5A. 8A is the protrusion of the guide part,
9 is a partition body, 10 is a semicircular groove provided in the partition body, 11
1 is a gasket as a sealing member in which a magnet is inserted into the periphery of the back surface of the doors 6A and 6B, 12 is the inside of the refrigerator, and 13 is the door 6.
This is a support arm that protrudes into the storage interior 13 at two locations, upper and lower, at a portion located inside the gasket 11 located on the non-pivot side of the back surface of A.

[0004] The operation of the refrigerator configured as described above will be explained below. 2 Kannon opening doors 6A
, 6B, the partition body 9 is rotatably supported on the back surface of the non-pivot side of the first door 6A with a length spanning the opening edge in the direction of the rotation axis of the door. When the partition body 9 is closed, it enters the chamber 12, and the projection 8A of the guide part 8 and the semicircular groove part 10 provided in the partition body 9 come into contact with each other and rotate. When the partition 9 is aligned with the semicircular groove 10, the front surface of the partition 9 is approximately flush with the opening 5A of the heat insulating box 5, and the gaskets 11 on the non-pivot sides of both doors are in contact with the front surface of the partition 10. It is possible to maintain airtightness inside the refrigerator.

[0005]

[Problems to be Solved by the Invention] However, in the above conventional configuration, when the opening is provided at the top or bottom of the main body, there is a difference between the outer box and the inner box, so the cold air inside the refrigerator directly hits the gasket surface. I think it has the disadvantage of poor cooling efficiency.

The present invention solves the above-mentioned problems, and includes a part of the guide part covering the difference between the outer box and the inner box to improve the sealing performance inside the refrigerator and the cooling efficiency. To provide a door device for a refrigerator-freezer that can also serve to improve positional accuracy.

[0007]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the refrigerator-freezer door device of the present invention includes a wall that prevents cold air from entering at the difference between the outer box and the inner box. It has a configuration that can be attached as a hit.

[0008]

[Operation] With the above-described structure, the present invention can reduce the amount of cold air directly hitting the surface of the gasket portion, thereby improving cooling efficiency. Furthermore, since the guide portion is mounted in contact with the inner box and the outer box, the positional accuracy of the guide portion protrusion can also be improved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. It should be noted that the same parts as those in the prior art are designated by the same reference numerals and the description thereof will be omitted.

FIG. 1 is a sectional view showing a door closed state of a door device of a refrigerator-freezer, and FIG. 2 is a perspective view of a guide portion in an embodiment of the present invention. Figure 3 is a sectional view taken from the B-B direction in Figure 2, and Figure 4
is a perspective view of the refrigerator-freezer, FIG. 5 is a front view of the insulation box, and FIG. 6 is a perspective view of the refrigerator-freezer.
shows a cross-sectional view taken along the line A-A. Reference numeral 14 denotes a decorative plate of a guide portion formed oppositely above and below the edge of the opening 5A of the heat insulating box 5 on the non-pivot side of each of the doors 6A and 6B, and 8 indicates the upper and lower sides of the opening 5A. The guide portions are opposed to each other. 8A are protrusions that protrude from the guide portions 8 facing each other from the upper and lower sides of the opening 5A. 10 extends vertically with a length slightly smaller than the upper and lower dimensions of the opening 5A, and has a flat front surface and a curved rear surface with curved corners. It is a semicircular groove 10 that is slidably fitted.

The operation of the refrigerator-freezer constructed as described above will be explained below. Outer side surface 8B of guide part 8
The gap can be eliminated by forming the box so as to cover the difference between the outer box 2 and the inner box 3.

As described above, according to this embodiment, the guide portion prevents cold air from directly hitting the gasket, thereby improving cooling efficiency.

[0013]

Effects of the Invention As described above, the present invention cools the gap caused by the difference between the outer box and the inner box of a refrigerator-freezer equipped with double-sided first and second doors by improving the shape of the guide section. This makes it possible to realize an efficient refrigerator-freezer.
