Description

Refrigerator with a door
Technical Field
The present invention relates to a refrigerator, and more particularly, to a refrigerator having a structure for supporting a rail of a door provided in a storage room.
Background
Various refrigerators having a drawer type door have been proposed (for example, see patent document 1). A movable rail that moves in the front-rear direction is attached to the door. Rollers are provided on the lower portion of the movable rail to move on the fixed rail fixed to the storage room. Further, a flange supported by a support structure rotatably attached to the storage room is formed at an upper portion of the movable rail. The fixed rail described in patent document 1 is integrally formed with a partition member that partitions the storage compartment.
Here, the lateral side surface of the container is formed in a tapered shape. The lateral side surface of the storage container is arranged closer to the center of the storage chamber in the lateral width direction of the storage chamber than the support structure. Therefore, if the support structure is located at a lower vertical position, the upper portion of the storage container does not need to be disposed closer to the center of the storage room in the lateral width direction of the storage room than the support structure. That is, if the vertical position of the support structure is low, the upper portion of the storage container may be disposed above the support structure. Therefore, if the vertical position of the support structure is low, the volume of the storage container can be suppressed from decreasing. In the refrigerator described in patent document 1, the rotatable support structure is located below the storage chamber, and therefore, the volume of the storage container can be suppressed from decreasing.
Patent document 1: japanese laid-open patent publication No. 11-6683
When the fixed rail is integrally formed with the partition member, the wall thickness of the fixed rail may be increased as compared with the partition member in order to secure the strength of the fixed rail. However, if the thickness is varied, the possibility of poor molding is increased.

The vacuum insulation piece HI3 is provided in contact with the 4 th surface portion 45b, and the foam insulation piece HI4 is provided around the vacuum insulation piece HI3 and on the upper side of the vacuum insulation piece HI3. The vacuum heat insulator HI3 is in contact with the 4 th surface portion 45b, and therefore, the effect of suppressing the transfer of cold energy of the freezing chamber 13 to the switching chamber 12 is enhanced.
[ Effect of the embodiment ]
The refrigerator 1 includes a partition member 44 and a fixed rail 43 independent from the 1 st surface portion 44a of the partition member 44. Therefore, even if the thickness of the resin constituting the 1 st surface portion 44a and the thickness of the resin constituting the fixed rail 43 are different, the 1 st surface portion 44a and the fixed rail 43 are formed separately, so that it is possible to avoid the molding failure of the partition member 44 and the molding failure of the fixed rail 43.
In addition, the fixed rail 43 is provided on the partition member 44. That is, the fixed rail 43 is disposed below the freezing chamber 13. Therefore, it is not necessary to dispose upper portion 60A (see fig. 12) of freezing compartment box 60 at the center of freezing compartment 13 in direction Dr2 with respect to fixed rail 43. That is, the upper portion 60A of the freezing chamber box 60 may be disposed on the fixed rail 43. Therefore, the refrigerator 1 can expand the width of the freezing compartment box 60 parallel to the direction Dr2, and can suppress the reduction in volume.
