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 pair of movable rails 40 correspond to the 1 st movable rail and the 2 nd movable rail of the present invention. The pair of support members 41 correspond to the 1 st support member and the 2 nd support member of the present invention. The pair of fixed rails 43 correspond to the 1 st and 2 nd fixed rails of the present invention. The reinforcing member 46 corresponds to the 1 st reinforcing member of the present invention.

The front surface portion of the freezer door 7 is a design surface. Freezer door 7 has a function of opening and closing freezer compartment 13. The user moves the freezing chamber door 7 forward and backward to open and close the freezing chamber 13. A pair of movable rails 40 are mounted on a rear surface portion of the freezer door 7. The movable rail 40 is mounted to the freezer door 7 by a fixing unit such as a screw.

The movable rail 40 is disposed parallel to the direction Dr 1. The movable rail 40 is movable in the direction Dr1 and in a direction opposite to the direction Dr 1. The movable rail 40 is supported by a support member 41. A rotating member 42 is attached to the movable rail 40. That is, the refrigerator 1 includes a pair of rotating members 42. The pair of rotating members 42 corresponds to the 1 st rotating member and the 2 nd rotating member of the present invention. When the freezing chamber door 7 is withdrawn, the rotating member 42 rolls on the fixed rail 43. This can reduce the force when the user pulls out the freezer door 7. The end of the movable rail 40 on the near side is attached to the freezer door 7, and the end of the movable rail 40 on the deep side is attached to the rotary member 42. The movable rail 40 is provided with a reinforcing member 46. A freezing chamber box 60 is mounted on the movable rail 40. That is, the movable rail 40 has a function of supporting the freezing chamber box 60.

The upper portion 43C is provided above the bottom portion 43A and the lower portion 43B. The upper portion 43C is provided above the contact surface portion 43D and the guide portion 43E. The upper portion 43C and the contact surface portion 43D are in contact with the inner case 2t2 together. The upper portion 43C is connected to the upper end of the contact surface portion 43D.

If the fixing member 48 is provided on the contact surface portion 43D, the fixing member 48 and the rotating member 42 may interfere with each other. In the refrigerator 1, the fixing member 48 is provided at the upper portion 43C, so that such interference can be avoided. The upper portion 43C is connected to the contact surface portion 43D.

The contact surface portion 43D includes: a surface opposed to the rotating member 42; and a contact surface with the inner case 2t2. Since the contact surface portion 43D is in surface contact with the inner box 2t2, the fixed rail 43 can be firmly fixed to the inner box 2t2.

The guide portion 43E and the bottom portion 43A face each other. The guide portion 43E has a function of restricting the movement of the upper side of the rotating member 42. The guide portion 43E is provided above the rotating member 42. The guide portion 43E is connected to the contact surface portion 43D.

The depth portion 43F is connected to the end portion on the depth side of the bottom portion 43A and the end portion on the depth side of the guide portion 43E. The deepening portion 43F is the deepest portion of the fixed rail 43.

[ partitioning members 44 and 45]

The partition member 44 includes a1 st surface portion 44a and a2 nd surface portion 44b. The 1 st surface portion 44a includes a contact portion 44a1 and a peripheral portion 44a2. In addition, the partition member 44 includes a recess 44C into which the lower portion 43B is inserted.

The 1 st surface 44a is formed with a recess 44C. In the embodiment, since the lower portion 43B is 2, the number of the recess portions 44C is also 2. The 1 st surface portion 44A includes an upper surface 44A of the partition member 44. The 1 st surface portion 44a may be made of resin. The recess 44C is formed in parallel with the fixed rail 43.

The contact portion 44a1 is a portion of the 1 st face portion 44a that is in contact with the vacuum insulation member HI1. The peripheral edge portion 44a2 is a portion of the 1 st surface portion 44a that is provided at the periphery of the contact portion 44a1, and is a portion that is not in contact with the vacuum insulation panel HI1. The recess 44C is formed in the peripheral edge portion 44a2 of the 1 st surface portion 44a.

The 2 nd surface portion 44b is provided below the 1 st surface portion 44a. The 2 nd surface portion 44B includes a lower surface 44B of the partition member 44.

Between the 1 st face portion 44a and the 2 nd face portion 44b, there are provided a vacuum heat insulator HI1 and a foaming heat insulator HI2. The vacuum insulation piece HI1 is provided in contact with the 1 st face 44a, and the foam insulation piece HI2 is provided around the vacuum insulation piece HI1 and under the vacuum insulation piece HI1. The vacuum heat insulator HI1 is in contact with the 1 st surface part 44a, thereby improving the effect of suppressing the transfer of cold energy of the freezing compartment 13 to the vegetable compartment 14. Further, since the recess 44C is formed in the peripheral edge portion 44a2 of the 1 st surface portion 44a, it is possible to avoid the vacuum heat insulator HI1 from being damaged due to interference between the recess 44C and the vacuum heat insulator HI1.

The partition member 45 includes a 3 rd surface portion 45a and a 4 th surface portion 45b. The 3 rd face 45A includes an upper surface 45A. The 4 th face 45B includes a lower surface 45B. The partition member 45 is also provided with a vacuum insulator HI3 and a foam insulator HI4. That is, between the 3 rd surface portion 45a and the 4 th surface portion 45b, the vacuum heat insulator HI3 and the foam heat insulator HI4 are disposed. 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.
