The horizontal sectional view of a refrigerator compartment door and a rotation partition main part. The horizontal sectional view of a refrigerator compartment door closed state.

  An embodiment of a refrigerator according to the present invention will be described with reference to FIGS. 1 to 6. FIG. 1 is a front external view of the refrigerator of the present embodiment. As shown in FIG. 1, the refrigerator 1 of the present embodiment includes, from above, a refrigerator room 2, ice making rooms 3 arranged at the same height and left and right. It is composed of an upper freezer room 4, a lower freezer room 5, and a vegetable room 6. The refrigerating room 2 includes front and rear refrigerating room doors 2a and 2b which are divided into left and right sides, and the ice making room 3, the upper freezing room 4, the lower freezing room 5, and the vegetable room 6 are respectively drawer-type ice making room doors. 3a, an upper freezer compartment door 4a, a lower freezer compartment door 5a, and a vegetable compartment door 6a.

  FIG. 2 is a perspective view when the first door 2a and the second door 2b of the refrigerator compartment are opened. The outside of the refrigerator 1 and the inside of the refrigerator are separated by a heat insulating box 7 formed by filling a foam heat insulating material (foamed polyurethane).

  The first door 2a and the second door 2b of the refrigerator compartment are pivotally attached to the left and right of the heat insulation box 7 by hinges 8a and 8b. The refrigerator doors 8a and 8b are made of a metal surface plate and a back surface made of a synthetic resin inner surface plate, and the surface plate and the inner surface plate are filled with a surface plate foam heat insulating material (foamed polyurethane).

  The rotary partition 10 is about the height of the refrigerator opening, and is rotatably attached to the bank 20 of the door inner surface plate by the hinge 12 to the first door 2a. When the refrigerator doors of the first door 2a and the second door 2b are closed, the gap between the doors is closed.

  A guide pin 11 for guiding the rotation of the rotary partition 10 is provided near the ceiling opening of the refrigerator compartment.

  A packing 9 containing a magnet 19 is attached to the entire rear surface of the door. When the door is closed, the iron plate at the opening edge of the heat insulating box 7 and the rotary partition 10 are in close contact with each other and the inside of the cabinet is airtight. Can keep sex.

  FIG. 3 is a horizontal sectional view between the doors of the refrigerator compartment when the first door 2a and the second door 2b are closed. The rotary partition 10 includes a U-shaped resin case 15 for storing a heat insulating material, a heat insulating material 16 such as styrofoam, and a surface iron plate 17. A dew prevention heater 18 is provided between the iron plate 17 and the heat insulating material 16 to overheat the surface of the rotating partition.

  An arcuate guide groove 13 as shown by a broken line in FIG. 3 is formed in the upper end portion of the rotary partition 10 so that a guide pin 11 provided on the ceiling of the refrigerator compartment enters. Further, the door inner plate and the rotary partition 10 are engaged by a spring 14, and when the rotary partition 10 is in front of a predetermined position, it rotates forward (clockwise) and rearward of the predetermined position. In some cases, the spring force acts so that the force works to rotate backward (counterclockwise).

  When the door is closed, the guide pin 11 provided on the ceiling of the refrigerator compartment enters the guide groove 13 at the upper end of the rotary partition 10, and the guide pin pushes the arc-shaped front side convex portion of the guide groove. As a result, the rotating partition rotates clockwise. When the door is completely closed, the rotary partition 10 is in a horizontal direction with the door surface and forms a receiving surface with the packing 9 provided on the back surface of the door.

  When the door is opened, the rotary partition 10 rotates counterclockwise by pushing the recess on the back side of the guide groove 13 when the guide pin 11 on the ceiling of the refrigerator compartment is retracted from the guide groove 13. When the door is opened and the rotary partition is at a predetermined angle, the rotary partition 10 is in a state perpendicular to the door surface (parallel to the bank 20) by the force of the spring 14.

  A fixed cold air shielding plate 22 formed of a resin member is installed on the inner door bank 20 of the first door 2a to which the rotary partition 10 is attached, and for the rotary partition 10 provided on the refrigerator ceiling. There is a length from a position lower than the guide pin 11 to the bottom of the refrigerator. The fixed cold air shielding plate 22 is attached to the door inner surface bank bank 20 at a position where the rotating partition 10 does not collide with the door surface when it is rotated in the vertical direction. The width dimension is set to a length that does not contact the other door when the second door 2b is opened and closed.

  FIG. 4 is a perspective view of the back surface of the second door 2b on which the rotating partition is not provided. A rotating cold air shielding means 23 formed of a resin member and having a length about the height of the refrigerator opening is rotatably attached to the bank 21 of the door inner surface plate by a hinge 25.

  A coil spring 30 as an urging means is attached to the rotating shaft of the hinge 25, and a force acts so that the rotating cold air shielding means 23 rotates counterclockwise. As a result, when the second door 2b is in the open state, as shown in FIG. 4, the rotating cold air shielding means 23 comes into contact with the pocket 26 attached to the door inner surface plate 21, and is approximately perpendicular to the door surface, that is, from the second door 2b. Since it is energized in the direction of leaving, it does not contact the first door 2a when closing the door.

  FIG. 5 is a horizontal sectional view of the vicinity of the upper part of the refrigerator compartment when the second door 2b is closed. A semicircular guide means 24 is provided at the upper end of the pivotable cool air shielding means 23. When the door is closed, the guide 27 for the cool air shielding plate provided on the refrigerator ceiling is provided. By pushing the guide means 24, the rotating cold air shielding means 23 rotates counterclockwise, and when the door is completely closed, it is fixed at a horizontal angle with the door surface.

  Further, if the width dimension of the fixed cold air shielding plate 22 and the rotatable rotating cold air shielding means 23 is set to such a length that the doors are in contact with each other when the doors are closed, the cold air directly hit from the refrigerator compartment is almost eliminated. The effect of reducing heat leak can be increased.

  However, if the width dimension of the fixed cold air shielding plate 22 is made too large, there is not much clearance between the fixed cold air shielding plate 22 and the second door 2b, and the possibility of a door collision increases, and the rotation can be turned freely. When the width dimension of the dynamic cold air shielding means 23 is increased, the rotating cold air shielding means 23 may obstruct the user's pocket insertion / removal operation. Therefore, as shown in FIG. 6, the tips of the cold air shielding plate 22 and the rotating cold air shielding means 23 are formed of soft members such as fillet packings 28 and 29, and the soft members are in contact with each other when both doors are closed. Keep the dimensions as appropriate. Thereby, it can prevent that a door and a cold air shielding board collide, and it can damage, and the heat leak reduction effect can also be acquired. It should be noted that at least one of the tips of the cold air shielding plate 22 and the rotating cold air shielding means 23 may be made of a soft member, thereby preventing damage due to contact and improving the sealing performance.

  As described above, the present invention provides a first door and a second door that are pivotally supported to the left and right of the refrigerator box so as to close the opening of the refrigerator compartment, and the first door. A refrigerator comprising a rotary partition provided to close the gap between the first door and the second door, wherein the door inner plate of the first door has a side closer to the refrigerator than the rotary partition. A cold air shielding plate extending to the second door side is provided, and the inner door plate of the second door is opposed to the cold air shielding plate and rotates when the second door is opened and closed. Dynamic cooling air shielding means is provided. Thereby, the heat leak between the doors of the double doors can be reduced, and the power saving performance can be improved.

  Further, the cold air shielding plate and the rotating cold air shielding means are in contact with the first door and the second door being closed. Thereby, the cold air from the refrigerator compartment which hits a rotation partition can be suppressed, and a heat leak can be reduced more.

  An arc-shaped guide means is provided at the upper end or lower end of the rotating cold air shielding means, and a guide pin for rotating the guide means when the second door is opened and closed is provided at the upper part of the refrigerator compartment. Thereby, when the door is in the closed state, the rotatable cold air shielding means can be held in such a direction as to reliably shield the cold air from the refrigerator.

  Further, an urging means for urging the rotating cold air shielding means in a direction away from the second door when the second door is opened is provided. Thereby, a rotation cold air shielding means does not contact the other door at the time of door opening.

  The tip of at least one of the cold air shielding plate and the rotating cold air shielding means is a soft member. As a result, the fixed cold air shielding plate and the rotatable rotating cold air shielding means are elastically deformed even when they come into contact with the door opening / closing operation, thereby further shielding the cold air leakage.

  In addition, the present invention is not limited to a door structure in which the gap between the doors is closed by a rotatable rotating partition provided on the inner plate of one door, as in this embodiment. Although it has a type door structure, it can be applied to a structure in which there is no rotating partition and the central gap is closed by a packing provided on the side surface on the pivot side of each door.
