  Hereinafter, embodiments will be described in detail with reference to the drawings.

[First Embodiment]
As shown in FIG. 1 and FIG. 2, the refrigerator 1 of the double door type door of the first embodiment is a refrigerator compartment 2 whose upper half is closed by two doors 11 and 12 that open and close the double door type. The vegetable compartment 3 is provided below, the ice making chamber 4 and the sub freezer compartment 5 are provided below, and the main freezer compartment 6 is further provided below. The vegetable compartment 3 contains a vegetable case 3A, the ice making room 4 contains an ice case 4A, the sub freezer compartment 5 contains a sub freezer compartment case 5A, and the main freezer compartment 6 contains a main freezer compartment case 6A. . In addition, drawer doors 3B, 4B, 5B, and 6B are attached to each.

  In the front opening of the refrigerator compartment 2, the opening is divided in the width direction, and the left-handed (leftward facing) left-handed left is pivotally supported by hinges 21 and 22 provided on the left and right sides of the refrigerator body. A door 11 and a right door 12 (to the right) are provided and are configured to be closed by both doors 11 and 12. Gaskets 141 and 142 each having a magnet 13 (see FIG. 3) inside are attached to the peripheral edges of the back surfaces of both doors 11 and 12, respectively. 1 and 2, a partition portion 15 having a length extending substantially over the entire length in the vertical direction is pivotally supported along with the gasket 141 on the back surface of the free end of the left door 11.

  The operation of sealing the refrigerator compartment 2 with the partition 15 and the gaskets 141 and 142 when both the doors 11 and 12 are opened and closed at the same time or when one of the doors is opened and closed is described in Patent Document 1. Is the same as That is, when the left door 11 is closed from the opened state where the partition portion 15 is in a posture substantially perpendicular to the door surface, the partition portion 15 rotates to a posture substantially parallel to the door surface by a spring action. As a result, the left half of the front side of the partition 15 faces the back side of the free end of the left door 11, and the right half of the front side of the partition 15 faces the back of the free end of the right door 12. The magnets 13 inserted in the gaskets 141 and 142 are attracted to the iron plate 17 on the surface of the partition part 15 so that the gaskets 141 and 142 are in close contact with the surface of the partition part 15 and the refrigerator compartment 2 is sealed. Become.

  In such a double doorfold refrigerator 1, the characteristic part of the present embodiment is the structure of the gaskets 141 and 142. As shown in FIG. 3, an iron plate 17 is disposed on the front side surface of the partition portion 15, and a heater 18 is disposed inside the partition portion 15 on the back surface of the iron plate 17.

  Each of the gaskets 141 and 142 attached to the back surfaces of the free ends of the left and right doors 11 and 12 is made of an elastically deformable material such as a flexible vinyl chloride resin material. A magnet 13 is inserted and is a flat and long one. And the inside is formed into a double structure so as to have a heat insulating space, and a heat transfer portion 144A is formed so as to have a double structure on the door free end side with respect to the internal heat insulating layer 143. At the same time, the heat insulating portion 144B is formed in a double structure on the door hinge end side. The heat insulation is enhanced by separating the heat insulation layer 143 and the heat transfer portion 144A and the heat insulation layer 143 and the heat insulation portion 144B by air. Further, the protruding length of the heat transfer portion 144A on the door free end side of the heat insulating layer 143 is set to be longer than the protruding length of the bag-shaped heat insulating portion 144B on the door hinge end side of the heat insulating layer 143. The heat receiving area of the heater 18 is increased.

  Further, the heat transfer portion 144A on the door free end side of each of the gaskets 141 and 142 is shaped so that a slight clearance is provided with respect to the iron plate 17 on the front side surface of the partition portion 15. This clearance is to prevent the heat transfer section 144A from directly contacting the iron plate 17 and directly receiving the heat of the heater 18 to reach a high temperature and quickly deteriorate.

  In the refrigerator 1 according to the present embodiment, in the state where the doors 11 and 12 are closed and the refrigerator compartment 2 is closed by the characteristic gaskets 141 and 142, the cold air on the refrigerator compartment 2 side is in direct contact. Is the heat insulating portion 144B formed on the door hinge end side of the heat insulating layer 143. Since the cold air in the refrigerator compartment 2 does not directly contact the heat insulating layer 143 as in the conventional case, the degree to which the heat insulating layer 143 is cooled by the cold air. Less than conventional. And heat transfer part 144A formed in the door free end side rather than heat insulation layer 143 receives the heat of heater 18 inside partition part 15 in a larger area than the case of only conventional heat insulation layer 143, and this It is possible to effectively prevent condensation on the surfaces of the heat insulating layer 143 and the heat transfer section 144A.

  In the present embodiment, the heat insulating portion 144B on the door hinge end side is not formed, and the heat transfer portion 144A is formed only on one side of the door free end side with respect to the heat insulating layer 143. The increase in shape may be reduced, thereby suppressing an increase in cost of the gaskets 141 and 142. Even in that case, the heat transfer part 144A formed on the door free end side with respect to the heat insulating layer 143 receives the heat of the heater 18 inside the partition part 15 in a wider area than the case of the conventional heat insulating layer 143 alone. Further, it is possible to more effectively prevent condensation on the surfaces of the heat insulating layer 143 and the heat transfer section 144A than in the past.

[Second Embodiment]

  According to the present embodiment, as in the first embodiment, when both the doors 11 and 12 are closed and the refrigerator compartment 2 is closed, the gaskets 141-1 and 142-1 in the refrigerator compartment 2 side. Since the cool air in the refrigerator compartment 2 is not in direct contact with the heat insulating layer 143 due to the presence of the heat insulating portion 144B on the door hinge end side that directly contacts the cold air, the degree to which the heat insulating layer 143 is cooled by the cold air is less than before. In addition, by receiving the heat of the heater 18 inside the partition portion 15 in a larger area than the first embodiment by the heat transfer portion 144A1 that protrudes larger on the door free end side than the heat insulating layer 143, It is possible to effectively prevent condensation on the surfaces of the heat insulating layer 143 and the heat transfer section 144A1. Furthermore, with the doors 11 and 12 closed and the refrigerator compartment 2 closed, the projecting end surfaces of the heat transfer section 144A1 are in contact with each other, so that the warm air in the space on the partition 15 side is external. It is possible to prevent the water from leaking out, and also from this surface, it is possible to effectively prevent condensation on the surfaces of the heat insulating layer 143 and the heat transfer portion 144A1.

  Even in the present embodiment, the heat insulating portion 144B on the door hinge end side can be omitted when cost reduction is required.

  As shown in FIG. 5, in the present embodiment, the gasket 141-2 attached to the left door 11 is the same as the gasket 141 of the first embodiment. The gasket 142-2 attached to the right door 12 is characterized in that a fin 145 is formed in the heat transfer section 144A on the door free end side. The shape of the heat insulating portion 144B on the door hinge end side of each of the gaskets 141-2 and 142-2 is the same as that of the first embodiment.

  According to the present embodiment, in the state where both doors 11 and 12 shown in FIG. 5 are closed and the refrigerator compartment 2 is closed, the cold air on the refrigerator compartment 2 side is the door hinge as in the first embodiment. Since it is in direct contact with the heat insulating portion 144B on the end side and not in direct contact with the heat insulating layer 143 as in the prior art, the degree to which the heat insulating layer 143 is cooled by cold air is less than in the prior art. And heat transfer part 144A formed in the door free end side rather than heat insulation layer 143 receives the heat of heater 18 inside partition part 15 in a larger area than the case of only conventional heat insulation layer 143, and this It is possible to effectively prevent condensation on the surfaces of the heat insulating layer 143 and the heat transfer section 144A. In addition, in the present embodiment, the fins 145 of the heat transfer section 144A are positioned so as to block the gap between the projecting end surfaces of both gaskets 141-2 and 142-2, and the outside air can freely enter this gap. This prevents the heat of the heater 18 from being confined in the gap, and more effectively prevents condensation on the surfaces of the heat insulating layer 143 and the heat transfer section 144A of both gaskets 141-2 and 142-2. it can.

  Also in this embodiment, the heat insulating portion 144B on the door hinge end side is not formed, and the heat transfer portion 144A is formed only on one side of the door free end side with respect to the heat insulating layer 143, and the gasket 141-2 is formed. An increase in the shape of the 142-2 may be reduced, thereby suppressing an increase in cost of the gaskets 141-2 and 142-2. Even in that case, the heat of the heater 18 inside the partition portion 15 is wider than that of the conventional heat insulating layer 143 only by the action of the heat transfer portion 144A and the fin 145 formed on the door free end side than the heat insulating layer 143. Heat is received by the area, and at the same time, the outside air can be prevented from entering the gap and the air heated by the heater 18 can be prevented from flowing out, and it is more effectively prevented from condensing on the surfaces of the heat insulating layer 143 and the heat transfer section 144A. it can.

[Fourth Embodiment]

It is formed. The shape of the heat insulating portion 144B on the door hinge end side of each of the gaskets 141-3 and 142-3 is the same as that of the first embodiment.

  According to the present embodiment, in a state where both doors 11 and 12 shown in FIG. 6 are closed and the refrigerator compartment 2 is closed, the cold air on the refrigerator compartment 2 side is the door hinge as in the first embodiment. Since it is in direct contact with the heat insulating portion 144B on the end side and not in direct contact with the heat insulating layer 143 as in the prior art, the degree to which the heat insulating layer 143 is cooled by cold air is less than in the prior art. And heat transfer part 144A formed in the door free end side rather than heat insulation layer 143 receives the heat of heater 18 inside partition part 15 in a larger area than the case of only conventional heat insulation layer 143, and this It is possible to effectively prevent condensation on the surfaces of the heat insulating layer 143 and the heat transfer section 144A. In addition, in the present embodiment, the fins 145 and 146 of the left and right heat transfer sections 144A are positioned so as to close the gap between the tips of the left and right gaskets 141-3 and 142-3, and the outside air can freely enter the gap. This prevents the penetration of the heater 18 and at the same time confines the heat of the heater 18 in the gap, and further condenses on the surfaces of the heat insulating layer 143 and the heat transfer section 144A of both gaskets 141-3 and 142-3. Can be prevented.

  Also in this embodiment, the heat insulating portion 144B on the door hinge end side is not formed, and the heat transfer portion 144A is formed only on one side of the door free end side with respect to the heat insulating layer 143, and the gasket 141-3 is formed. An increase in the shape of 142-3 may be reduced, thereby suppressing an increase in cost of gaskets 141-3 and 142-3. Even in that case, due to the action of the heat transfer part 144A and fins 145, 146 formed on the door free end side with respect to the heat insulating layer 143, the heat of the heater 18 inside the partition part 15 is more than the case of the conventional heat insulating layer 143 alone. In addition, it can receive heat over a wide area, and at the same time, the outside air can be prevented from entering the gap and the air heated by the heater 18 can be prevented from flowing out. Can be prevented.
