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 that does not hinder the delivery of food such as a refrigerator having a double door.

Means for Solving the Problems To solve the above problems, the refrigerator door device of the present invention comprises a pair of guide portions that are formed as curved columns at the opening edge portions located on the non-pivotal sides of both doors, and One door is rotatably supported on the back surface of the non-pivot side portion of the door with a length extending to the opening edge, and enters the inside of the warehouse with the closing operation of the first door, and is positioned on the curved column of the guide portion. This is a configuration in which a partition body having a curved guide groove portion is provided.

Action The present invention has the above-described configuration, in which the partition body rotatably supported on the back surface of the non-pivotal side portion of the first door enters the inside of the refrigerator as the first door is closed, and is curved. The front surface of the partition body is substantially flush with the opening and the gaskets on the non-pivotal side of both doors are the above-mentioned partitions when the end of the groove is located on the guide protrusion of the curved column provided at the opening edge on the non-pivotal side of both doors. While keeping the inside of the refrigerator airtight by abutting against the front of the body, the partition body intrudes out of the refrigerator in the opposite operation to the closing operation accompanying the opening operation of the first door without reducing the internal volume, It will not be an obstacle when food is delivered through the opening.

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 so as 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, the curved column 12A has an opening 5
It projects from the upper and lower sides of A, facing 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. When the doors 7A and 7B are closed, the gasket 8 is provided with the opening 5 of the heat insulating box 5.
Magnetize the front edge of the outer case 2 of A and seal the inside 9. 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. First support arm 13
The second support arm 14 is attached to the support shaft 15 so as to be rotatable in the horizontal direction at the tip end of the, and the cut-off body 16 is attached to the tip end of the second support arm 14. The partition body 16 is formed into a prismatic shape from the short side and the 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 contacts the support shaft 18 of the first support arm 13, and the other end 17A is a support shaft of the second support arm 14. It abuts 19. 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, and a curved guide groove portion 16A slidably fitted to the curved column 12A of the guide portion 12 at the upper and lower ends. Are formed.
The starting end of the guide groove portion 16A is open on the short side of the partition body.

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
Due to the elastic force of the coil spring 17, 16 is always stable at the position as shown by the chain double-dashed line in FIG. 1 when viewed from the door 7A. When the door 7A is closed in this state, the partition body 16 penetrates into the compartment 9 and the curved guide groove portions 16A at the upper and lower ends of the partition body 17 abut the curved column 12A of the guide portion 12, and the door 7A is further closed. When closed, the partition body 17 rotates counterclockwise in FIG. 2 against the elastic force of the coil spring 17 along the curved column 12A, and the curved guide groove portion 16A guides at the same time when the door 7A is closed. Curved column 12A of part 12
The curved guide groove portion 16A is positioned at the terminal end portion 16B and conforms to it. This state is shown in FIG. At this time, the front surface of the partition 16 is substantially flush with the opening 5A, and the doors 7A, 7B
The non-pivotally-sided gasket 8 is in close contact with the front surface of the partition body 16 and hermetically seals the interior 9.

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, the curved guide groove portion 16A of the partition body 16 slides on the curved column 12A of the guide portion 12 against the elastic force of the coil spring 15 by pulling the door 7A toward you. 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, according to the present invention, first and second doors of the gannon-opening type are rotatably supported on both sides of the opening so as to close the opening of the heat insulating box having the opening, and both doors. Gaskets that are respectively provided on the peripheral edges of the back surface of the door and contact the peripheral edges of the openings, guide portions that project as curved pillars curved inward toward the opening edge portions that are located on the non-pivotal sides of the doors, and the first door Of the non-pivot side portion of the guide portion extending in the rotation axis direction of the door and rotatably supported by the length extending over the opening edge and entering the inside of the compartment when the first door is closed. A partition body having a curved guide groove portion that abuts on a curved surface of the guide portion and that abuts on a curved column of the guide portion to rotate, and the partition body has a guide groove portion terminal end located in the guide portion. The front surface of the partition body is substantially flush with the opening, and the gaskets on the non-pivotal side of the both doors and the front surface of the partition body When the first door is closed, the partition body comes into contact with the curved column of the guide section and is positioned at the end of the curved guide groove section. At this time, the gaskets of both doors come into close contact with the partition body. The inside of the cabinet is sealed, and when the first door is opened, the partition is separated from the guide part and pulled out of the cabinet together.Therefore, in order to bring the non-pivot side gasket of the door into contact with the heat insulation box, Since it is not necessary to provide painting materials and the like, the entire opening surface of the heat-insulating box can be used for delivering foods, which has the effect of improving usability. Furthermore, since the guide part is a curved column,
Since the force applied to the guide part when opening and closing the partition can be dispersed, it is difficult to get wet.

In addition, since the guide portion is curved, when the door enters the guide groove portion, rattling of the partition body is small when the door on the side having no partition body is opened and closed.
