When the second door packing 23 provided in b approaches the second door packing 23 provided in the opening / closing door 20a, both door packings 23 repel each other with the N pole-N pole of both magnets 23d facing each other. In the state in which the opening / closing door 20b is completely closed, the N pole-S poles of both magnets 23d attract each other and are in close contact with each other at their opposing end faces 23e, so that the cabinet main body 10 is shown in FIG.
It is sealed as shown in.

FIG. 6 shows a case where the right and left doors 20b and 20b are closed and the right and left doors 20b are to be opened. When the opening / closing door 20b is slightly pivoted forward, both door packings 23 are rocked back and forth to be in close contact with each other, and are separated by the subsequent pivoting operation of the opening / closing door 20b.

As described above, in the double-door type refrigerator, by closing all the opening and closing doors 20a to 20d, it is possible to surely close the cabinet body 10 in a hermetically sealed state, and to freeze each door packing 23. Condensation can be prevented, and heat can be prevented from entering the inside of the refrigerator main body 10 from the outside and cold air from the inside of the refrigerator main body 10 can be prevented from leaking to the outside.

Further, in the double door type refrigerator,
The support member 24 that supports the door packing 23 has the mounting hole 2
It is attached to the opening / closing doors 20a to 20d by screwing a screw 24f passing through 4d to a predetermined portion of the fixing member 27, and the attaching hole 24d is oval in the left-right direction, so the screw 24f is loosened. The support member 24 can be moved in the left-right direction in the closed state. Thereby, the mounting position of the support member 24 in the left-right direction can be adjusted, and the position of the door packing 23 in the left-right direction can be adjusted. When adjusting the position of the door packing 23 in the left-right direction, the amount of deviation can be visually confirmed by the positional relationship between each line 24e and the head of the screw 24f.

Therefore, the manufacturing accuracy of the door packing 23,
If a sealing failure occurs between the opening / closing doors 20a and 20b or between the opening / closing doors 20c and 20d due to assembly accuracy or long-term use, visually check the gap where the sealing failure occurs. Then, the support member 24 is attached to the opening / closing doors 20a to 20.
By adjusting the position in the left-right direction with respect to d, it is possible to easily eliminate the sealing failure between the opening / closing doors 20a and 20b and between the opening / closing doors 20c and 20d.

In the double-door type refrigerator, a plurality of linear strips 24e extending in the vertical direction are provided on the surface of the support member 24 in parallel with each other at a predetermined interval, and screws for fixing the linear strips 24e and the support member 24 are provided. Since the visual means is constituted by 24f, the visual means can be configured simply and with good appearance.

Further, in the double door type refrigerator,
Since the door packing 23 is configured to be detachably supported by the support member 24, the door packing 23 can be easily cleaned and the door packing 23 can be easily replaced.

In the double-door type refrigerator, however, the facing end surface 23e of the second door packing 23 is horizontally angled with respect to the reference line L1 orthogonal to the front opening 11 of the cabinet body 10. Because of the shape, the contact area of the opposing end faces 23e of the two door packings 23 when the left and right doors 20a, 20b, 20c, 20d are closed is the same as the contact area of the two door packings that do not have the above angle. Is larger than that of both open / close doors 20a, 20
It is possible to further improve the airtight seal between the opposed ends of b, 20c, and 20d, and to suppress the occurrence of freezing and dew condensation.

In addition, the second door packing 23 has a shape in which the facing end surface 23e is horizontally angled with respect to the reference line L1 orthogonal to the front opening 11 of the cabinet body 10. Since the entire shape of the door packing 23 is not changed, there is no need to change the structure of the mounting portion on the opening / closing door side, and there is also a restriction from the relationship with the opening / closing door. Absent.

Further, in the double-door type refrigerator, since the left and right door packings 23 are in the state of being expanded rearward relative to each other, the front end corner portion of the door packing 23 of the receiving side opening / closing door 20a in the closed state. On the other hand, the turning locus of the rear end corner portion of the door packing 23 of the opening / closing door 20b which is being closed is located at a position away from each other. Therefore, both doors 2
0a, 20b and both opening / closing doors 20c, 20d are prevented from interfering with each other on both the left and right door packings 23 during closing of the both opening / closing doors 20a, 20b, both opening / closing doors 20c, 2
0d can be closed smoothly.

12 to 15 show modified examples of the second door packing. The door packing 23A is substantially different from the door packing 23 in that the opposite end surface 23e is inclined in the opposite direction, and the other points are basically similar.

The second door packing 23A is a tubular body 2
3a, a leg portion 23b having an L-shaped cross section, a long rubber packing main body having a connecting portion 23c for connecting them, and a plurality of prismatic magnets 23d having a predetermined length. Similar to the packing 23, the magnets 23d are embedded in the cylindrical main body 23a at a predetermined interval in the vertical direction, and the N poles are arranged so that the N poles are located on the front side and the S poles are located on the rear side. On the other hand, in the opening / closing door 20b on the right side, the N pole is arranged on the rear side and the S pole is arranged on the front side.

However, in the door packing 23A, when it is attached to the support member 24, the facing end surface 2
3e is formed at a horizontal angle with respect to a reference line L1 orthogonal to the front opening 11 of the cabinet body 10, and intersects the reference line L1 and a tangent line L2 extending in the front-rear direction of the facing end surface 23e. The angle is θ. That is, in the door packing 23A, the facing end surface 23e is inclined by the angle θ with respect to the reference line L1, and the left and right door packings 23A are opposite to the door packing 23, and
It is configured as an inclined surface that expands from 0 to the front.

In the double-door type refrigerator having the second door packing 23A having the above structure, like the refrigerator using the door packing 23 as the second door packing,
When all the open / close doors 20a to 20d are closed, the opposite end portions of the open / close doors 20a to 20d facing each other are sealed. 12 to 15 show a state in which the left side opening / closing door 20a is closed and the right side opening / closing door 20b is closed.

FIG. 12 shows a state in which the left side opening / closing door 20a is closed and immediately before the right side opening / closing door 20b is closed. In this state, after closing the left opening / closing door 20a, the right opening / closing door 20b is closed, and the opening / closing door 20b is rotated rearward so that the second door packing 23A provided on the opening / closing door 20b is closed. When approaching the second door packing 23A provided on the opening / closing door 20a, both door packings 23
In A, the N pole-N pole of both magnets 23d face each other and repel each other (see FIG. 13), but when the opening / closing door 20b further rotates, the N pole-S poles of both magnets 23d attract each other (FIG. 1).
4), when the opening / closing door 20b is completely closed,
The north and south poles of both magnets 23d attract each other and are in close contact with each other at their opposing end faces 23e (see FIG. 15), and the left and right door packings 23A seal between the opposite end portions of each opening / closing door 20a-20d.

By the way, in the refrigerator, since the left and right door packings 23A are in a state of being expanded to the front of each other, the front end corner portion of the door packing 23A of the receiving side opening / closing door 20a is closed. The door packing 23A of the opening / closing door 20b on the way is located away from the turning locus of the rear end corner of the door packing 23A. Therefore, both open / close doors 20a,
The left and right door packings 23A do not interfere with each other during the closing of the 20b and the both open / close doors 20c, 20d, and the both open / close doors 20a, 20b, the both open / close doors 20c, 20d.
Can be closed more smoothly.

The above configuration is applied to the double-sided refrigerator of the present invention, but such a configuration is similarly applied to various double-sided storages such as a double-sided freezer and a double-sided warm storage. Thus, it is possible to obtain the same operational effect.
