Description

   Refrigerator   

The present invention relates to a refrigerator, and more particularly, to a refrigerator including a structure supporting a rail provided at a door of a storage compartment.

It is proposed to include a pull-out door in a refrigerator (for example, refer to Patent Document 1). The door is mounted on a movable rail that moves in the front-rear direction. On the lower part of the movable rail, a roller fixed on a fixed rail fixed to a storage room is provided. In addition, a flange supported by a support structure rotatably attached to the storage room is formed on an upper portion of the movable rail. In addition, the fixed rail described in Patent Document 1 is integrally formed in a partition member that partitions the storage room.

Here, the lateral sides of the storage container are formed in a gradient shape. The lateral side of this storage container is arranged closer to the center of the storage room in the widthwise direction than the support structure in the storage room. Therefore, if the support structure is lower in the up and down position, the upper part of the storage container does not need to be arranged closer to the center of the storage room in the horizontal direction than the support structure in the storage room. That is, if the support structure is lower in the up-down position, the upper part of the container can also be arranged on the upper side of the support structure. Therefore, the lower the up and down position of the support structure, the smaller the volume of the storage container can be suppressed. In the refrigerator described in Patent Document 1, since the rotatably supporting structure is located on the lower side of the storage compartment, it is possible to suppress a reduction in the volume of the storage container.

[About partition member 44 and partition member 45]

FIG. 18 is a cross-sectional view showing the vacuum heat insulating member HI1 and the foam heat insulating member HI2 of the partition member 44 of the refrigerator 1 according to the embodiment.

FIG. 19 is an explanatory diagram showing the vacuum heat insulating member HI3 and the foam heat insulating member HI4 of the partition member 45 of the refrigerator 1 of the embodiment.

The partition member 44 includes a first surface portion 44a and a second surface portion 44b. The first surface portion 44a includes a contact portion 44a1 and a peripheral edge portion 44a2. The partition member 44 includes a recessed portion 44C into which the lower portion 43B is inserted.

The recessed portion 44C is formed in the first surface portion 44a. In the embodiment, since the lower portion 43B is two, the recessed portion 44C is also two. The first surface portion 44 a includes an upper surface 44A of the partition member 44. The first 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 first surface portion 44a that is in contact with the vacuum heat insulating member HI1. The peripheral edge portion 44a2 is a portion of the first surface portion 44a provided at the peripheral edge of the contact portion 44a1, and is a portion that is not in contact with the vacuum heat insulating member HI1. The recessed portion 44C is formed in the peripheral edge portion 44a2 of the first surface portion 44a.

The second face portion 44b is provided on a lower side than the first face portion 44a. The second surface portion 44 b includes a lower surface 44B of the partition member 44.

The vacuum heat insulating member HI1 and the foam heat insulating member HI2 are provided between the first surface portion 44a and the second surface portion 44b. The vacuum heat insulating member HI1 is provided in contact with the first surface portion 44a, and the foam heat insulating member HI2 is provided around the vacuum heat insulating member HI1 and below the vacuum heat insulating member HI1. Since the vacuum heat insulating member HI1 is in contact with the first surface portion 44a, the effect of suppressing the heat and cold of the freezer compartment 13 from being transmitted to the vegetable compartment 14 is increased. In addition, since the recessed portion 44C is formed on the peripheral edge portion 44a2 of the first surface portion 44a, it is possible to avoid damage to the vacuum insulation member HI1 due to interference between the recessed portion 44C and the vacuum insulation member HI1.

The partition member 45 includes a third surface portion 45a and a fourth surface portion 45b. The third face 45a includes an upper surface 45A. The fourth face 45b includes the lower face 45B. The partition member 45 is also provided with a vacuum heat insulating member HI3 and a foam heat insulating member HI4. That is, between the third surface portion 45a and the fourth surface portion 45b, a vacuum heat insulating member HI3 and a foam heat insulating member HI4 are disposed. The vacuum heat insulating member HI3 is provided so as to be in contact with the fourth surface portion 45b. The foam heat insulating member HI4 is provided around the vacuum heat insulating member HI3 and above the vacuum heat insulating member HI3. Since the vacuum heat insulating member HI3 is in contact with the fourth surface portion 45b, the effect of suppressing the heat and cold of the freezing chamber 13 from being transmitted to the switching chamber 12 is increased.

[Effect of the implementation form]

The refrigerator 1 includes a partition member 44 and a fixed rail 43 that is separated from the first surface portion 44 a of the partition member 44. Therefore, even if the thickness of the resin constituting the first surface portion 44a and the thickness of the resin constituting the fixed rail 43 are different, since the first surface portion 44a and the fixed rail 43 are separately formed, defective formation of the partition member 44 can be avoided. And the formation of the fixed rail 43 is defective.

The fixed rail 43 is provided on the partition member 44. That is, the fixed rail 43 is arranged below the freezer compartment 13. Therefore, the upper part 60A (refer to FIG. 12) of the freezer compartment box 60 need not be disposed closer to the center of the freezer compartment 13 in the direction Dr2 than the fixed rail 43. That is, the upper part 60A of the freezer compartment box 60 may be arranged on the fixed rail 43. Therefore, the refrigerator 1 can expand the width of the freezer compartment box 60 parallel to the direction Dr2, and can suppress the reduction in volume.

[First Modification]

Fig. 20 is a first modification of the refrigerator 1 according to the embodiment.

The refrigerator 1 of the first modification includes not only the reinforcing member 46 but also a reinforcing member 46B and a reinforcing member 46C. The reinforcing member 46B corresponds to a second reinforcing member of the present invention. The reinforcing member 46C corresponds to a third reinforcing member of the present invention. One end of the reinforcing member 46B is provided on one movable rail 40 and the other end is provided on the other movable rail 40. The reinforcing member 46B is provided closer to the freezing compartment door 7 than the reinforcing member 46. The reinforcing member 46B is a plate-like member. One end of the reinforcing member 46C is provided on the reinforcing member 46, and the other end is provided on the reinforcing member 46B. The reinforcing member 46C is also a plate-like member. The reinforcing member 46B may be fixed to the movable rail 40 or may not be fixed. The reinforcing member 46C may be fixed to the reinforcing member 46 and the reinforcing member 46B, or may not be fixed.

The refrigerator 1 of the first modification example includes not only the reinforcing member 46 but also the reinforcing member 46B and the reinforcing member 46C, so that the area of the member supporting the freezer compartment box 60 can be further increased. Accordingly, the bending of the freezer compartment box 60 can be more suppressed, and damage to the freezer compartment box 60 can be avoided.

[Second Modification]

Fig. 21 is a second modification of the refrigerator 1 according to the embodiment.

In the embodiment, a plurality of lower portions 43B are formed on the fixed rail 43. The lower part 430B of the fixed rail 43 of the refrigerator 1 of the second modification is singular. However, the width of the lower portion 430B parallel to the direction Dr1 is longer than the width of the lower portion 43B parallel to the direction Dr1. Further, the width of the recessed portion 440C parallel to the direction Dr1 is also the size corresponding to the width of the lower portion 430B parallel to the direction Dr1. The width of the lower portion 430B parallel to the direction Dr1 may be set to, for example, 2/3 or more of the width of the fixed rail 43 parallel to the direction Dr1. The refrigerator 1 according to the second modification can also obtain the same effects as the refrigerator 1 of the embodiment.
