The present invention relates to a refrigerator, and more particularly to the structure of a double door.

Generally, a refrigerator has storage rooms such as a refrigerator compartment, a vegetable compartment, and a freezer compartment, and one of the storage compartments, for example, the refrigerator compartment is a double door. This double door type door is a rotating partition that rotates in conjunction with one of a pair of left and right doors (hereinafter referred to as a first door and a second door), for example, the first door. When the door is closed, the rotating partition is brought into close contact with the magnet packings on the inner surfaces of the first door and the second door to ensure the airtightness of the refrigerator compartment (for example, Patent Document 1). reference).

FIG. 7 shows a double door in a refrigerator described in Patent Document 1. The double door type door includes a first door 101 and a second door 102. In any one of the first door 101 and the second door 102, in FIG. 7, a rotary partition 103 is provided on the inner surface of the end of the left first door 101. The rotating partition 103 is attracted by the magnet of the magnet packing 104 attached to the outer periphery of the inner surface of the first door 101 and the second door 102 when the door is closed, and is in close contact with the magnet packing 104 so that the airtightness of the refrigerating chamber 105 is reached. Is secured.

With such a configuration, the gap 106 generated at the abutting end portion of the first door 101 and the second door 102 is sealed by the close contact between the magnet packing 104 and the rotary partition 103, and the inside of the refrigerator compartment 105 is airtight. Kept.

However, in the conventional double doors as described above, when the first door 101 provided with the rotating partition 103 is opened, a larger force is required than when the second door 102 is opened. There is a problem that the feeling when opening the door and the second door is different, giving the user a sense of incongruity.

That is, the first door 101 is urged toward the magnet packing 104 as indicated by an arrow a by the reversing spring 107 such as a coil spring when the rotary partition 103 provided on the first door 101 is closed, and when the door is opened. , And is biased toward the door shelf wall surface 108 as indicated by an arrow b. Further, on the first door 101 side, when the first door is opened, a guide provided at the upper opening of the refrigerator compartment 105 resists the rotating partition 103 against the urging force of the reversing spring 107, and the arrow b Adds force to rotate in the direction. For this reason, a larger force is required when opening the first door 101 than when opening the second door 102.

As a result, the force to open the first door 101 requires a larger force than the force to open the second door 102, which causes a problem that the user feels uncomfortable.

FIG.

1 to 5, the refrigerator 200 is divided into a plurality of storage rooms in the refrigerator main body 1 by

partition members

2, 3, and 4. In the plurality of storage rooms, a refrigerator compartment 5 is arranged at the top, and a drawer type ice making room 6 and a switching room 7, a freezing room 8, and a vegetable room 9 are arranged below the storage room. Each storage room is provided with a door. In the present embodiment, the door of the refrigerating room 5 is constituted by a double door with a rotary first door 11A and a second door 11B. Yes. Further, the

doors

12, 13, 14, and 15 provided in the ice making chamber 6, the switching chamber 7, the freezing chamber 8, and the vegetable chamber 9, respectively, are constituted by drawer type doors.

As shown in FIG. 3 and FIG. 5, the first door 11A and the second door 11B of the double doors of the refrigerator compartment 5 are rotated to the first door 11A on the left side in this embodiment. A partition 16 is provided. The rotating partition 16 is configured to be in close contact with the magnet packing 17 provided on the inner periphery of each of the first door 11A and the second door 11B when the door is closed to keep the refrigerator compartment 5 airtight. . The magnet packing 17 is, for example, a bag-like packing in which

magnets

17A and 17B are built.

As shown in FIG. 5, the rotary partition 16 is pivotally supported by the hinge member 18 at the end of the first door 11 A in the vertical direction of the refrigerator 200. In addition, the rotary partition 16 is configured such that a front plate 19 and a rear plate 20 having a substantially U-shaped cross section are fitted and joined, and a heat insulating material 22 is provided in an internal space thereof. The rotating partition 16 is provided with a reversing spring 23 made of a coil spring that is suspended between the rotating partition 16 and a hinge member 18 attached to the first door 11A. With such a configuration, when the first door 11A is closed, the rotary partition 16 is in close contact with the magnet packing 17 provided on the inner periphery of the first door 11A and the second door 11B. When the first door 11A is opened, it is urged to the inside of the first door 11A, that is, the shelf side wall surface 21 side.

Further, the front plate 19 of the rotating partition 16 is made of a magnetic metal and is configured to be attracted to the

magnets

17A and 17B of the magnet packing 17.

The magnetic force of the

magnets

17A and 17B of the magnet packing 17 is the magnetic force of the magnet 17A on the first door 11A side where the rotating partition 16 is provided, that is, the second door 11B where the rotating partition 16 is not provided. It is set to be smaller than the magnetic force of the magnet 17B on the side.

That is, the adhesion force between the first door 11A on the side where the rotary partition 16 is provided and the rotary partition 16 is such that the second door 11B and the rotary partition 16 on the side where the rotary partition 16 is not provided. It is set so as to be smaller than the adhesion force.

The operation effect of the door is demonstrated about the refrigerator 200 comprised as mentioned above.

As shown in FIG. 5, the first door 11 A and the second door 11 B that open and close the refrigerating chamber 5 are attached to the reversing spring 23 by the rotating partition 16 provided in the first door 11 A when closed. The

magnets

17A and 17B of the magnet packing 17 provided on the first door 11A and the second door 11B are positioned along the inner surfaces of the first door 11A and the second door 11B. It is adsorbed on the front plate 19 of the body 16 to keep the refrigerator compartment 5 airtight.

At this time (when the door is opened), on the first door 11A side, a guide provided at the upper opening of the refrigerating chamber 5 resists the urging force of the reversing spring 23, and the rotating partition 16 is moved to the arrow b in FIG. Adds force to rotate in the direction. For this reason, the direction when opening the first door 11A requires a larger force than when opening the second door 11B, and it feels heavier when opening the first door 11A.

However, in the case of the double doors of the present embodiment, the magnetic force of the magnet 17A of the magnet packing 17 of the first door 11A is set smaller than the magnetic force of the magnet 17B of the magnet packing 17 of the second door 11B. Therefore, the force for rotating the rotary partition 16 applied to the first door 11A can be offset accordingly. In other words, even if there is a force necessary to rotate the rotary partition 16, the force that opens the first door 11A is the force of the magnet 17A of the magnet packing 17 and the force of the magnet 17B on the second door 11B side. It can be made smaller by setting it smaller than this. As a result, the force when opening the first door 11A and the force when opening the second door 11B, that is, the second door against the magnetic force of the magnet 17B of the magnet packing 17 of the second door 11B. The force for opening 11B can be set to substantially the same level.

Therefore, it is possible to suppress the difference between the force that the user feels when opening the first door 11 A and the force that opens the second door 11 B, and to provide a refrigerator that suppresses the uncomfortable feeling that the user feels when the door is opened. can do.

(Embodiment 2)
FIG. 6 is a cross-sectional view of a main part of the double door of the refrigerator 200 according to the second embodiment of the present invention.

The rotating partition 16 of the refrigerator 200 according to the present embodiment is configured such that at least the front plate 19 is formed of a resin plate such as ABS, and the

partition magnets

24A and 24B are incorporated therein.

The

partition magnets

24A and 24B are incorporated in portions of the magnet packing 17 mounted on the first door 11A and the second door 11B so as to face the

magnets

17A and 17B. The magnetic poles are set so that 17A and 17B are attracted to each other. The magnetic force of the partition magnet 24A on the first door 11A side is set smaller than the magnetic force of the partition magnet 24B on the second door 11B side, and the first door 11A on the side where the rotary partition 16 is provided. And the rotating partition 16 are set to be smaller than the contacting force between the second door 11B on the side where the rotating partition 16 is not provided and the rotating partition 16.

Since the other configuration of the refrigerator 200 of the present embodiment is the same as that of the first embodiment, the same reference numerals are given and description thereof is omitted.

Since the double doors configured as described above are set so that the magnetic force of the partition magnet 24A on the first door 11A side is smaller than the magnetic force of the partition magnet 24B on the second door 11B side, Similar to the first embodiment, even if a force for rotating the rotary partition 16 is applied to the first door 11A side, the force for opening the first door 11A is substantially the same as the force for opening the second door 11B. Can be about.

Further, according to the configuration of the present embodiment, the front plate 19 of the rotary partition 16 is formed of a resin plate having low heat transfer properties, so that condensation is unlikely to occur on the surface. Therefore, it is not necessary to provide a dew condensation prevention heater, which is required when the front plate 19 of the rotating partition 16 is made of metal, in the rotating partition 16 and to energize it occasionally. Thereby, the structure of the rotation partition 16 can be simplified and energy saving can be improved.

In the present embodiment, the rotating partition 16 is provided by setting the magnetic force of the partition magnet 24A on the first door 11A side smaller than the magnetic force of the partition magnet 24B on the second door 11B. The adhesion force between the first door 11A, which is the door on the other side, and the rotating partition 16 is the adhesion force between the second door 11B, which is the door on which the rotation partition 16 is not provided, and the rotating partition 16. Although the configuration set to be smaller is illustrated, the configuration is not limited to such a configuration. For example, it may be performed as follows.

That is, the magnet 17A magnetic force of the magnet packing 17 provided on the first door 11A, not the magnet magnetic force of the

partition magnets

24A and 24B, is set smaller than the magnet 17B magnetic force of the magnet packing 17 provided on the second door 11B. Also good. Alternatively, the magnet magnetic force of the partition magnet 24A on the first door 11A side is made smaller than the magnet magnetic force of the magnet packing 17 on the second door 11B, or the magnet 17A magnetic force of the magnet packing 17 on the first door 11A side is It is smaller than the magnet magnetic force of the partition magnet 24B on the second door 11B side, etc., and is not particularly limited.

(Embodiment 3)
The third embodiment of the present invention will be described by substituting FIG. 6 used in the second embodiment. As in the second embodiment, the rotary partition 16 has a surface formed of resin, and a partition magnet 24A corresponding to each magnet packing 18 of the first door and the second door inside thereof. 24B is provided. In addition, the rotary partition 16 is a first door on the side where the rotary partition 16 is provided, with the resin thickness of the front plate 19 of the part of the rotary partition 16 facing the

partition magnets

24A and 24B being different from each other. The contact force between 11A and the rotating partition 16 is configured to be smaller than the contact force between the second door 11B on the side where the rotating partition 16 is not provided and the rotating partition 16. Specifically, the resin thickness of the front plate 19 of the portion of the rotary partition 16 that faces the partition magnet 24A is greater than the resin thickness of the front plate 19 of the portion of the rotary partition 16 that faces the partition magnet 24B. It is formed thick.

With such a configuration, even if the surface of the rotary partition 16 is made of resin, the force for opening the first door and the second door can be made substantially the same by simply changing the resin thickness. The uncomfortable feeling felt by the user with a simple configuration can be suppressed, and the reliability can be improved. Further, as in the second embodiment, the surface of the rotating partition 16 is made resin, so that it is possible to suppress the occurrence of condensation on the surface, and the installation of a condensation prevention heater or the like can be unnecessary or simplified, Energy saving can also be improved. Further, since only the resin thickness of the front plate 19 is changed, the production cost can be reduced as compared with the case where magnets having different magnetic forces are used.

As mentioned above, although this invention has been demonstrated using embodiment, it cannot be overemphasized that this invention is not limited to this and can be variously changed within the range which achieves the objective of this invention. That is, it should be considered that the above embodiment is illustrative in all respects and not restrictive. That is, the scope of the present invention is not limited to the above description, but is defined by the claims, and is intended to include meanings equivalent to the claims and all modifications within the scope.

As described above, the present invention can provide substantially the same force required when the left and right doors of the double doors are opened, can suppress a sense of discomfort given to the user when the doors are opened, and provides a highly reliable refrigerator. can do. Therefore, it can be widely used for many uses such as commercial refrigerators and showcases as well as home use.
