Description

  Embodiments of the present invention relate to a refrigerator having a double door.

  Conventionally, a refrigerator has been proposed in which a pair of left and right double doors are pivotally supported by hinges provided on both left and right sides of a refrigerator compartment so as to close the refrigerator compartment.

  In this refrigerator, in order to fill a gap between the pair of left and right double doors, a rotary vertical partition is provided on the back surface of one door on the side opposite to the pivot.

JP 2009-250602 A

  Also in the vertical partition, a heater wire is embedded to prevent dew. However, this heater wire requires a connection part with the lead wire drawn out from the inside of the door, and when the heater wire and the connection part are attached to the back surface of the vertical partition, the part of this connection part is not heated. , The heat conduction decreases accordingly. Therefore, in order to ensure the dewproof performance, there is a problem that the energization rate for the heater wire has to be increased.

  Therefore, in view of the above problems, the present invention provides a refrigerator that can ensure dew-proof performance without increasing the energization rate of the heater wire.

An embodiment of the present invention includes a pair of left and right double doors pivotally supported on both left and right sides of a front opening of a storage chamber to close the opening, and one of the double doors. And a vertical partition that is attached to the anti-pivot support side and closes between the double doors by rotating according to the operation of the opening and closing door. The heater wire is disposed on the back surface of the front wall of the vertical partition, the right storage recess and the left storage recess are respectively provided on both side surfaces of the heat insulating member, and both ends of the heater wire connected to the two lead wires. The refrigerator is characterized in that the portions are respectively stored in the right storage recess and the left storage recess of the heat insulating member in a state of being separated from the back surface of the front wall.

  Next, the upper hinge support portion 64 and the lower hinge support portion 66 are fitted to the pair of upper and lower hinges 32, 32 in the left door 24. In this case, a coiled spring 68 that is inserted into the lower hinge 32 and biases the vertical partition 30 in parallel with the left door 24 is attached to the lower hinge support portion 66.

  Next, the lead wire fixing member 62 is fixed to the right side portion of the left door 24, and the connector 76 is connected to an electrical connection portion in the left door 24 and connected to the power supply source of the heater wire 40.

(5) Effect According to the present embodiment, the heater wire 40 is arranged in an S shape from the upper part to the lower part of the back surface of the front wall 32 of the vertical partition 30, and the one end portion 40 a and the other end portion of the heater wire 40. 40 b extend to the left storage recess 50 and the right storage recess 54 provided on the left and right side walls of the heat insulating member 38. Therefore, the heater wire 40 can be disposed on the front wall 32 in a space-saving manner, and the front wall 32 can be evenly heated from the upper part to the lower part, thereby ensuring dewproof performance. Therefore, the energization rate with respect to the heater wire 40 can be lowered as compared with the conventional case, which saves energy.

  Moreover, since the one end part 40a and the other end part 40b of the heater wire 40 are rotated from the side wall of the heat insulating member 38 to the rear surface and stored in the storage recess 52 after being attached, the size of the vertical partition 30 can be reduced and assembled. Work is improved.

  Moreover, since the one end part 40a and the other end part 40b of the heater wire 40 are stored in the left storage recess 50 and the right storage recess 54 on both sides of the heat insulating member 38, the size of the vertical partition 30 is reduced. In addition, both end portions 40a and 40b can be securely fixed and the assembling work is facilitated.

  Both end portions 40a and 40b of the heater wire 40 routed after the heat insulating member 38 are connected to the first lead wire 44 and the second lead wire 48 by the first connecting portion 42 and the second connecting portion 46, respectively. This connection operation can be performed on the rear surface of the heat insulating member 38, and the assembly operation is facilitated.

  Further, since the second lead wire 48 passing between the first connection portion 42 and the second connection portion 46 is covered with the protective member 58, the heater wire 40 is not damaged.

  Moreover, since the 1st lead wire 44 and the 2nd lead wire 48 are pulled out from the one drawer hole 72, the size of the vertical partition 30 can be made small, and assembly workability | operativity improves.
