Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door device such as a refrigerator in which an opening of a heat insulating box is opened and closed by a double door type door and a back gasket is provided with a gasket for sealing.

Conventional Technology A conventional example will be described with reference to FIGS. 7 and 8.

Reference numeral 1 denotes a refrigerator main body, which constitutes a heat insulating box body 5 that is opened forward from an outer box 2, an inner box 3 and a foam heat insulating material 4 filled between both boxes 2 and 3, and the opening of this heat insulating box body 5 The double doors 7A, 7B are pivotally supported by upper and lower hinges 6A, 6B on the left and right edges of the portion 5A so as to be openable and closable. Door 7A,
A gasket 8 as a seal member having a magnet inserted therein is attached to the peripheral portion of the back surface of 7B. In addition, a closing member 10 is attached to the inside 9 of the back surface of the non-pivotal side to extend along the opening edge and extend in the direction of the pivot axis of the door to partition the opening. When the 7B is closed, the front side of the outer box 2 of the opening 5A of the heat insulating box 5 and the front surface of the closing member 10 are magnetized to store the inside 9
Seal.

SUMMARY OF THE INVENTION However, in the above-described structure, the gaskets provided on the back surfaces of both doors must form a surface with which the gasket located on the non-pivotal side of the door abuts in order to keep the inside of the refrigerator airtight. Therefore, there is a problem in that a closing member that partitions the opening of the heat-insulating box is attached, and this closing member has a problem that it reduces the internal volume of the refrigerator and hinders the delivery of food from the opening.

In view of the above problems, the present invention provides a door device for a refrigerator or the like that does not interfere with the delivery of food such as a refrigerator having a double door.

Means for Solving the Problems In order to solve the above problems, the door device of the refrigerator or the like of the present invention is a guide portion formed in a columnar shape at the opening edge portions located on the non-pivotal side of both doors, A half that is rotatably supported on the rear surface of the non-pivot side portion of the first door and has a length that extends to the opening edge and that is inserted into the guide portion when the first door is closed and enters the storage compartment. This is a configuration in which a partition body in which the starting end of the circular groove is opened on the short side is provided.

Action The present invention has a semi-circular shape in which the partition body rotatably supported on the back surface of the non-pivotal side portion of the first door intrudes into the inside of the compartment with the closing operation of the first door. The front surface of the partition is substantially flush with the opening and the gaskets on the non-pivotal side of both doors are the partition bodies with the end of the groove of the door being located at the guide portion provided on the opening edge on the non-pivotal side of both doors. It keeps the inside of the refrigerator airtight by abutting against the front surface, and when the opening operation of the first door is performed in the closing operation, the partition body intrudes to the outside by the reverse operation. It will not get in the way when the food is delivered.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 to 6. The description of the same parts as the conventional one will be omitted. In FIG. 4, a front view of the heat insulating box 5 is shown in FIG.
On the inner surfaces of both side walls of the inner box 3, a plurality of net rack rails 11 extending in the front-rear direction are integrally formed at substantially the same horizontal position. Door 7A, 7B
Guide portions 12 are formed to face each other above and below the edge of the opening 5A of the heat insulating box 5 in the portions located on the respective non-pivotal sides. In this guide portion 12, cylinders 12A project from above and below the opening 5A so as to face each other.

Here, the guide portion 12 may be integrally formed with the inner box 3 or may be attached as a separate member.

A gasket 8 as a seal member having a magnet inserted therein is attached to the peripheral portions of the back surfaces of the doors 7A and 7B. This gasket 8 is for opening the opening 5A of the heat insulating box 5 when the doors 7A, 7B are closed.
The outer box 2 is magnetized to the front edge and the inside 9 is sealed. A first support arm 13 projecting upward and downward in two directions toward the inside 9 is attached to a portion located inside the gasket 8 located on the non-pivotal side of the back surface of the door 7A. FIG. 6 shows an enlarged view of this first support arm 13 portion. A second support arm 14 is horizontally rotatably attached to a support shaft 15 at the tip of the first support arm 13, and a partition 16 is attached to the tip of the second support arm 14. The partition 16 is formed of a prism having a short side and a long side. A coil spring 17 is attached to a support shaft 15 to which the second support arm 14 is attached.
One end of the coil spring 17 is in contact with the support shaft 18 of the first support arm 13, and the other end 17A is in contact with the support shaft 19 of the second support arm 14. When the door 7A is opened, the partition body 16 is rotated to the position shown by the chain double-dashed line by the elastic force of the coil spring 17. Further, the partition body 16 extends vertically with a length slightly smaller than the vertical dimension of the opening 5A,
The front surface has a flat surface and the rear portion has a shape with curved corners, and a semicircular groove 16A that slidably fits into the cylinder 12A of the guide portion 12 is formed at the upper and lower ends. Also, groove 16A
Is formed with an opening on the short side.

Next, the operation will be described with reference to FIGS. First, since the opening / closing operation of the door 7B is conventional in general, the description is omitted. Next, the state in which the door 7A is opened is not shown, but at that time the partition body
The coil spring 17 is always stable at the position shown in FIG. 2 as viewed from the door 7A by the elastic force of the coil spring 17. When the door 7A is closed in this state, the partition body 16 invades the inside 9 and eventually the partition body 17
When the semicircular groove 16A at the upper and lower ends abuts on the cylinder 12A of the guide portion 12 and further closes the door 7A, the partition body 17 resists the elastic force of the coil spring 17 along the cylinder 12A. Rotate counterclockwise, and when the door 7A is closed, the semicircular groove 16A
Is the cylindrical portion 12A of the guide portion 12 and the end portion 16B of the semicircular groove 16A.
Located at and matches it. This state is shown in FIG. At this time, the front surface of the partition body 16 is substantially flush with the opening 5A, and the gasket 8 on the non-pivotal side of the doors 7A and 7B is the partition body 16.
The inside 9 is airtightly sealed by closely contacting with the front surface.

Here, the partition body 16 may be made of synthetic resin or the like, but if only the front surface is made of a magnetic material, the gasket 8 on the non-pivotal side is formed.
Will be even better. Further, the width of the partition body 16 is set in advance so as to be sufficiently larger than the gap between the gaskets 8 on the non-pivotal side.

Next, when the door 7A is opened, by pulling the door 7A toward you, the semicircular groove 16A of the partition 16 slides against the elastic force of the coil spring 15 and slides on the column 12A of the guide portion 12 in FIG. It is rotated clockwise so that the non-pivotal side gasket 8 is separated from the partition 16. If the door 7A is further rotated in the opening direction, the partition 16 is rotated clockwise in FIG. 2 by the coil spring 15, and then the door 7A is easily rotated and opened.

Since there is no member that partitions the opening 5A of the heat insulating box 5, food can be delivered easily.

EFFECTS OF THE INVENTION As described above, the door device for a refrigerator or the like according to the present invention includes the first door of the gannon door type that is rotatably pivoted on both sides of the opening so as to close the opening of the heat insulating box having the opening. A second door, gaskets provided on both sides of the back surface and abutting on the opening edges, and a single columnar guide portion projectingly formed on the opening edges located on the non-pivotal sides of the doors , A non-pivotally-sided portion of the first door extending in the rotation axis direction of the door over a length extending to the opening edge and rotatably supported to enter the inside of the refrigerator with the closing operation of the first door. It is composed of a rectangular columnar partitioning body having a short side and a long side having a semicircular groove into which the guide portion is inserted and rotated to insert the guide portion. The semicircular opening start end is formed on one side, and the guide is formed at the end of the semicircular groove of the partition. With the front face of the partition body substantially flush with the opening with the parts positioned, the non-pivotal side gaskets of both doors and the long sides of the partition body are in contact with each other. There is no need to provide fixed partitioning materials to bring the gasket on the pivot side into contact, and the entire open surface of the heat insulating box can be used for food delivery, improving usability and the short side of the partition. Since the starting end where the guide portion is inserted is located at the position, the partition body that abuts on the guide portion and rotates can be smoothly moved. Further, since the guide portion has a single columnar shape, when the door is opened, the guide portion does not enter the field of view of the user so much that the view of opening is not obstructed.
