A gasket 8 serving as a sealing member into which a magnet is inserted is attached to the peripheral edge of the back surface of 7B. In addition, a closing member 10 is attached to the interior 9 on the back side of the non-pivotal side, extending in the direction of the rotation axis of the door with a length spanning the opening edge, and partitioning the opening. When the opening 7B is closed, the front edge of the outer box 2 of the opening 5A of the heat insulating box 5 and the front surface of the closing material 10 are magnetized to seal the inside 9 of the refrigerator.

Problems to be Solved by the Invention However, in the above configuration, in order to keep the inside of the refrigerator airtight with the gasket provided on the back side of both doors, it is necessary to form a surface against which the gasket located on the non-pivot side of the door comes into contact. Therefore, a closing material is installed to partition the opening of the insulating box, and this blocking material reduces the internal volume of the refrigerator and also obstructs the pattern of food coming out from the opening. Ta.

In view of the above-mentioned problems, the present invention provides a door device for a refrigerator, etc., which does not interfere with the display of food items, such as a refrigerator having a double-opening door.

Means for Solving the Problems In order to solve the above problems, the door device for a refrigerator, etc. of the present invention includes a pair of guide portions formed protrudingly as cylinders at the opening edges located on the non-pivot sides of both doors. The door is rotatably supported on the back surface of the non-pivot side part of the first door with a length spanning the opening edge, and as the first door closes, it enters the refrigerator and hits the cylinder of the guide part. This is a configuration in which a partition body having semicircular grooves is provided.

Function: According to the present invention, the partition body rotatably supported on the back surface of the non-pivotal side portion of the first door enters into the refrigerator with the closing operation of the first door, and forms a semicircular shape. With the end of the shaped groove located at the guide part of the column provided on the opening edge of the non-pivotal side of both doors, the front surface of the partition is between the opening and the road surface -2, and the gasket on the non-pivotal side of both doors is It comes into contact with the front of the partition to maintain airtightness inside the refrigerator, and when the first door opens and closes, the partition moves in the opposite direction and leaks out of the refrigerator, without reducing the internal volume of the refrigerator. Also, it will not get in the way when food is ejected from the opening.

Embodiment Below, an embodiment of the present invention will be explained according to FIGS. A front view is shown.A plurality of net shelf rails 11 are integrally formed on the inner surface of both side walls of the inner box 3 and extend back and forth at approximately the same horizontal position.Door 7
A guide part 12 is formed at the bottom of the opening 5A of the opening 5A of the heat-insulating box 5 on the non-pivot side of each of A and 7B so as to face each other. A cylinder 12A protrudes from the upper and lower sides of the opening 5A, facing each other.

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

A gasket 8 as a sealing member into which a magnet is inserted is attached to the periphery of the back surface of the doors 7A and 7B.

When the doors 7A and 7B are closed, this gasket 8 is magnetized to the front edge of the outer box 2 of the opening 5A of the heat insulating box 5 to seal the inside 9 of the refrigerator. A first support arm 13 is attached to a portion of the back surface of the door 7A located on the non-pivot side and located inside the gasket 8 in two places, vertically, and protrudes in the direction 9 inside the refrigerator. What is this in Figure 6? An enlarged view of the 'g1 support arm 13 portion is shown.

A second support arm 14 is attached to the tip of the first support arm 13 so as to be rotatable in the horizontal direction on a support shaft 15.
A partition 16 is attached to the tip of the second support arm 14. A coil spring 17 is attached to the support shaft 16 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 the support shaft of the second support arm 14. It is in contact with 19. When the door 7A is opened, the partition 16 is rotated to the position shown by the two-dot chain 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 is flat, and the rear portion has curved corners, and semicircular grooves 16A are formed at the upper and lower ends to slidably fit into the cylinder 12A of the guide portion 12.

Next, the operation will be explained with reference to FIGS. 1 and 2.

First, since the opening/closing operation of the door γB is conventionally common, a description thereof will be omitted. Next, although the state in which the door 7A is open is not shown, the partition body 16 is always stabilized at the position shown by the chain double-dashed line in FIG. 1 when viewed from the door 7A due to the elastic force of the coil spring 17. When the door 7A is closed in this state, the partition 16 enters the inside of the refrigerator 9, and eventually the semicircular grooves 16A at the upper and lower ends of the partition 17 come into contact with the cylinder 12A of the guide part 12, and the door 7A is further closed. As it closes, the partition 17 rotates counterclockwise in FIG. 2 along the column 12A against the elastic force of the coil spring 17, and at the same time closes the door 7A, the semicircular groove 16A closes.
is located at and coincides with the cylindrical column 12A of the guide portion 12 and the terminal end 16B of the semicircular groove 16A. This state is the first
As shown in the figure. At this time, the front surface of the partition body 16 has an opening 5A.
The gasket 8 on the non-pivot side of the doors 7A and 7B is in close contact with the front surface of the partition 16 to airtightly seal the interior 9 of the refrigerator.

Here, the partition body 16 may be made of synthetic resin or the like, but if only the front side is made of a magnetic material, the gasket 8 on the non-pivotal side
The adhesion becomes even better. Further, the width of the partition body 16 is set to be sufficiently larger than the interval between the gaskets 8 on the non-pivot side.

Next, when opening the door 7A, by pulling the door 7A toward you, the semicircular groove 1eA of the partition 16 slides on the cylinder 12A of the guide part 12 against the elastic force of the coil spring 16, as shown in FIG. The gasket 8 on the non-pivot side is moved away from the partition 16 by being rotated clockwise. When 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, it is easy to pattern the food.

Effects of the Invention As described above, the present invention provides the first stage of the Kannon opening ceremony. A pair of protruding cylindrical guide portions are provided on the non-pivot side of the opening of the insulated box of a refrigerator or the like equipped with a second door. A partition body is rotatably provided on the back surface of the non-pivot side of the first door, and this partition body extends in the direction of the rotational axis of the door and is connected to the insulating box body. The length spans the edge of the opening, and a semicircular groove located at the cylinder of the guide part is formed at the end of the partition, so that the gaskets on the non-pivot sides of both doors are in close contact with the front surface of the partition. When the first door is closed, the partition comes into contact with the cylinder of the guide part and is located at the end of the semicircular groove, and at this time, the gaskets of both doors are in close contact with the partition and the inside of the refrigerator is closed. When the first door is opened, the partition separates from the guide part and is pulled out of the refrigerator, so a partitioning material or the like is placed on the insulation box so that the gasket on the non-pivot side of the door comes into contact with it. There is no need to provide this, and the entire opening surface of the heat insulating box can be used for patterning the food, which has the effect of improving usability.
