Fig. 2 is a perspective view showing a structure of a heat insulating box in the refrigerator 1 of the present invention.

The heat-insulating box body is formed of a top surface, a bottom surface, both side surfaces, and a back surface, and has a box shape with an opening front surface. The heat insulating box includes an outer box 7 (see fig. 1) made of metal and an inner box 8 made of synthetic resin, and a space inside the heat insulating box formed by the outer box 7 and the inner box 8 is filled with a foamed heat insulating material 9 such as a rigid polyurethane foam by so-called in-situ foaming to insulate the storage compartment from the outside.

The outer case 7 is formed in a box shape by a top plate and left and right side plates formed by bending a thin steel plate into a door shape, a back plate made of other members, and a bottom plate made of other members. On the other hand, the inner case 8 is formed into a case shape by molding a synthetic resin plate. The top panel and the left and right side panels may be separate.

The refrigerating compartment 2, the ice making compartment 3, and the upper freezer compartment 4 are partitioned by a heat insulating partition 10 disposed in a substantially horizontal plane. A lower-stage freezing chamber 5 is disposed below (directly below) the ice making chamber 3 and the upper-stage freezing chamber 4, and the lower-stage freezing chamber 5 and the vegetable chamber 6 are partitioned by a heat insulating partition 11 disposed in a substantially horizontal plane. The heat insulating partitions 10 and 11 are provided in portions of the storage compartments that divide different temperature zones, and function is achieved such that the inside of the refrigeration temperature zone is not supercooled by the cool air in the refrigeration temperature zone or is not warmed by the cool air in the refrigeration temperature zone.

Further, a vacuum heat insulating material 19 having a lower thermal conductivity than the foam heat insulating material 9 is attached between the outer case 7 and the inner case 8 in addition to the foam heat insulating material 9, and the heat insulating performance is improved without reducing the food storage volume. In the present embodiment, as shown in fig. 1B, a vacuum heat insulating material is also provided in the lower freezer door 5a and the vegetable room door 6a. Specifically, the vacuum heat insulator 5b is provided in the lower freezer door 5a, and the vacuum heat insulator 6b is provided in the vegetable room door 6a.

Here, in order to secure gas barrier properties, the vacuum heat insulating material is constituted by wrapping a core material such as glass wool with an outer wrapping material formed of a metal layer such as aluminum. The vacuum heat insulating material is adhered to the inner wall surface of the outer case 7, that is, the inner wall surface of each of the top plate, the side plate, the back plate, and the bottom plate by using an adhesive such as a double-sided tape or a hot melt adhesive for a part or the whole surface of the vacuum heat insulating material.

The ice making compartment 3 and the upper freezer compartment 4 will be described with reference to fig. 3 and 4. Fig. 3 is a top view of the ice making compartment 3 and the upper freezer compartment 4 of the refrigerator 1 of the present invention as viewed from above. Fig. 4 is a top view of the ice maker 31 removed from fig. 3.

The ice making chamber 3 is provided with: an ice maker 31 having an ice making tray; an ice making chamber container 32 disposed below the ice maker 31; and a cool air duct (cool air duct or pipe) 33 that guides cool air generated by the cooler 15 (refer to fig. 1B) to the ice maker 31 and the ice making compartment container 32. The duct 33 is disposed on the rear side with respect to the ice making chamber 3 and the upper freezer compartment 4.

The ice making compartment container 32 includes a first container portion 321, a second container portion 322, and a shovel placement portion 323. The first container 321 and the second container 322 are configured as container parts (housing parts) adjacent in the left-right direction, and are partitioned by a partition wall 324. The first container portion 321 and the second container portion 322 are formed as an integrated container (ice making compartment container 32). The shovel placement portion 323 is disposed in a region of the first container portion 321.

The first container 321 is disposed in a range including immediately below the ice maker 31. The first container portion 321 is an ice storage portion (ice storage container portion) that stores ice made by the ice maker 31. Ice produced by the ice maker 31 falls from the ice maker 31 to the inside of the ice storage portion 321, and is automatically stored in the ice storage portion 321.

The second container portion 322 is disposed in a range deviated in the left-right direction from immediately below the ice maker 31. The second container portion 322 is partitioned from the ice storage portion (first container portion) 321 by a partition wall 323, and can serve as a small article accommodating portion (small article accommodating portion) for accommodating articles other than ice generated by the ice maker 31.

The ice storage portion 321 is disposed outside in the left-right direction of the refrigerator 1, and the small article insertion portion 322 is disposed inside in the left-right direction of the refrigerator 1.

The shovel placement unit 323 is disposed in front of the ice maker 31 and has a floor surface (bottom surface) higher than the floor surface (bottom surface) of the ice storage unit 321. In this case, a part of the floor surface of the ice storage portion 321 is disposed below the shovel placement portion 323. By making the floor surface of the shovel placement portion 323 higher than the floor surface of the ice storage portion, the hand of the user who takes the shovel can be prevented from coming into contact with ice. Further, by disposing a part of the floor surface of the ice storage portion 321 below the shovel placement portion 323, ice can be stored below the shovel placement portion 323, and the volume of the ice storage portion 321 can be increased.

An upper freezer compartment container 41 is provided in the upper freezer compartment 4. In the present embodiment, the ice making compartment container 32 has a width dimension W32 that can be inserted into the upper freezer compartment 4, and the upper freezer compartment container 42 has a width dimension W42 that can be inserted into the ice making compartment 3. Therefore, it is necessary to prevent the ice making compartment container 32 from being erroneously assembled in the upper freezer compartment 4 or the upper freezer compartment container 42 from being erroneously assembled in the ice making compartment 3.

With reference to fig. 5 and 6, the ice making compartment door 3a and the upper freezer compartment door 4a will be described.

The ice making compartment door 3a is mounted on a fixed rail (door receiving portion) 39 mounted on the inner box 8 side of the refrigerator 1 via a movable rail (door mounting portion) 37.

As shown in fig. 6, the upper freezer door 4a includes: an outer plate 45 exposed outside the case; an inner plate 46 provided inside the case; a foamed heat insulating material (not shown) provided between the outer plate 45 and the inner plate 46; and a movable rail (door mount) 47 mounted to the inner plate 46. The movable rail 47 of the upper freezer door 4a is fixed by being attached to the fixing portion 461 of the upper freezer door 4a. The upper freezer door 4a is attached to a fixed rail (door receiving portion) 49 attached to the inner box 8 side of the refrigerator 1 via a movable rail (door attaching portion) 47.

In the present embodiment, the movable rail (door mount) 37 of the ice making compartment door 3a and the movable rail (door mount) 47 of the upper freezer compartment door 4a are formed in the same shape and size. Therefore, the movable rail 37 of the ice making compartment door 3a can be attached to the fixed rail (door receiving portion) 49, and the movable rail (door attaching portion) 47 of the upper freezer compartment door 4a can be attached to the fixed rail (door receiving portion) 39.

That is, in the refrigerator 1 of the present embodiment, when the ice making compartment door 3a is the first door and the upper freezer compartment door 4a is the second door, the refrigerator includes the first door 3a having the first door mount 37 and attached to the first door receiver 39, and the second door 4a having the second door mount 47 and attached to the second door receiver 49, and the first door mount 37 is attachable to the second door receiver 49 and the second door mount 47 is attachable to the first door receiver 39.

In the present embodiment, the outer and inner plates 35 and 36 of the ice making compartment door 3a and the outer and inner plates 45 and 46 of the upper freezer compartment door 4a are formed in the same shape and size. Then, at least the inner plate 36 of the ice making compartment door 3a and the inner plate 46 of the upper-stage freezing compartment door 4a are shared.

The respective inner plates 36 and 46 of the ice making compartment door 3a and the upper freezer compartment door 4a will be described with reference to fig. 7. Fig. 7 is a plan view of the ice making compartment door 3a and the upper freezer compartment door 4a of the refrigerator 1 of the present invention as viewed from the back side, with the movable rails 37, 47 removed.

The inner panel 36 of the ice making compartment door 3a includes: a first group first fixing portion 361 for fixing the movable rail 37 (see fig. 5); and a second group first fixing portion 461 configured to be capable of fixing the movable rail 47 at substantially the same position as the first group first fixing portion 361 before half rotation in a state where the inner plate 36 is half rotated about the drawing direction as an axis.

The inner panel 46 of the upper-stage freezing chamber door 4a includes: a first group second fixing portion 461 that fixes the movable rail 47 (refer to fig. 6); and a second group second fixing portion 361 configured to be able to fix the movable rail 37 at substantially the same position as the first group second fixing portion 461 before half rotation in a state of half rotation about the pulling direction as an axis.

Here, the "substantially identical position" refers to a misalignment between the ice making compartment door 3a and the upper-stage freezing compartment door 4a to such an extent that the sharing of the inner plates 36 and 46 is allowed.

That is, in the refrigerator 1 of the present embodiment, when the ice making compartment door 3a is the first door and the upper freezer compartment door 4a is the second door, the movable rail 37 of the ice making compartment door 3a is the first door mounting portion, and the movable rail 47 of the upper freezer compartment door 4a is the second door mounting portion. The fixed rail 39 that receives the movable rail 37 of the ice making compartment door 3a is a first door receiving portion, and the fixed rail 49 that receives the movable rail 47 of the upper freezer compartment door 4a is a second door receiving portion. In this case, the first door receiver 39 is disposed in the ice making chamber 3 in which the ice maker 31 is housed, and the second door receiver 49 is disposed in another storage chamber (upper-stage freezing chamber door 4 a) different from the ice making chamber 3.

In the refrigerator 1 of the present embodiment, the inner panel 36 of the first door (ice making compartment door) 3a includes: a first group first fixing portion 361 that fixes the movable rail 37; and a second group first fixing portion 461 configured to fix the movable rail 47 at substantially the same position as the first group first fixing portion 361 before half rotation even if the inner plate 36 is half-rotated about the pulling direction as an axis.

The inner panel 46 of the second door (upper-stage freezing chamber door) 4a includes: a first group second fixing portion 461 that fixes the movable rail 47; and a second group second fixing portion 361 configured to be able to fix the movable rail 37 at substantially the same position as the first group second fixing portion 461 before half rotation even if half rotation is performed with the drawing direction as the axis.

In the refrigerator 1 of the present embodiment, the first door (ice making compartment door) 3a and the second door (upper freezer door) 4a are disposed adjacent to each other in the left-right direction, and the inner plates 36, 46 have concave-convex shapes 363, 364, 463, 464 different from each other on one side and the other side in the left-right direction.

The inner plates 36 and 46 have concave-convex shapes for suppressing leakage of cool air from the storage compartments 3 and 4, but have different shapes on the left and right outer sides and on the partition side of the ice making compartment door 3a to the upper freezer compartment door 4a. In the ice making compartment door 3a, the concave-convex shapes 363 and 364 are necessary, but in the concave-convex shape 364, the necessary portion is a portion A, B, and the C portion in the concave-convex shape 364 is not necessary. On the other hand, in the upper freezer door 4a, the concave-convex shapes 463 and 464 are necessary, but in the concave-convex shape 464, the necessary portion is a portion A, B, and the C portion in the concave-convex shape 464 is not necessary.

The C portion of the concave-convex shape 364 and the C portion of the concave-convex shape 464 are provided for sharing the inner plate 36 of the ice making compartment door 3a and the inner plate 46 of the upper-stage freezing compartment door 4a. The concave-convex shape 463 is not required for the inner plate 36 of the ice making compartment door 3a, but the concave-convex shape 463 is provided for the inner plate 36 of the ice making compartment door 3a in order to share the inner plate 36 of the ice making compartment door 3a with the inner plate 46 of the upper freezer compartment door 4a. Similarly, the concave-convex shape 363 is not required for the inner plate 46 of the upper-stage freezing chamber door 4a, but the concave-convex shape 363 is provided for the inner plate 46 of the upper-stage freezing chamber door 4a in order to realize the sharing of the inner plate 36 of the ice making chamber door 3a and the inner plate 46 of the upper-stage freezing chamber door 4a.

The inner panel 36 of the ice making compartment door 3a and the inner panel 46 of the upper-stage freezing compartment door 4a are provided with: a sign 362 indicating or indicating the name of the storage compartment corresponding to the ice-making compartment door 3a, in the case where the inner panel 36 of the ice-making compartment door 3a and the inner panel 46 of the upper-stage freezing compartment door 4a are used as the inner panel 36 of the ice-making compartment door 3a, the sign being oriented positively (the right, left, right, up, down, and left, right, up, down of the letter match the attached state); and a sign 462 for indicating or suggesting the name of the storage compartment corresponding to the upper freezer door 4a in the case where the inner plate 36 of the ice making compartment door 3a and the inner plate 46 of the upper freezer door 4a are used as the inner plate 46 of the upper freezer door 4a, the positive orientation (the right and left and upper of the letter matches the right and upper of the attached state).

In this way, in a state where the door is held accurately in the vertical direction, whether the door is the ice making compartment door 3a or the upper freezer compartment door 4a can be accurately identified based on the marks 362 and 462 read in the positive direction.

Next, a structure for preventing erroneous assembly of the ice making compartment container 32 will be described with reference to fig. 8 to 10. Fig. 8 is a perspective view of an ice making compartment container 32 provided in the ice making compartment 3 of the refrigerator 1 of the present invention. Fig. 9 is a plan view illustrating a structure for preventing erroneous assembly of the ice making compartment container 32. Fig. 10 is a perspective view illustrating a structure for preventing erroneous assembly of the ice making compartment container 32.

In the ice making compartment door 3a and the upper freezer compartment door 4a, since the components such as the inner plates 36 and 46 and the movable rails 37 and 47 are shared, a case is considered in which the ice making compartment container 32 is erroneously attached to the fixed rail 49 of the upper freezer compartment 4.

In order to prevent such erroneous assembly, the ice making compartment container 32 includes protruding portions (ribs) 325a protruding rearward on the side portions 325 located on the left and right outer sides. When the ice making compartment container 32 is accommodated in the upper freezer compartment 4, the protrusion 325a abuts against the inner wall of the upper freezer compartment 4 or an arrangement arranged in the upper freezer compartment 4, so that the ice making compartment door 3a cannot be closed. In the present embodiment, the pipe 33 disposed on the rear side with respect to the ice making chamber 3 and the upper freezer compartment 4 is provided with an abutting portion 332 that abuts against the protruding portion 325a. When the ice making compartment container 32 is accommodated in the upper freezer compartment 4, the protruding portion 325a abuts against the abutting portion 332, and the upper freezer compartment door 4a cannot be closed.

In addition, the protruding portion (rib) 325a blocks a gap formed at the rear side of the ice storage portion 321 of the ice making compartment container 32, and has an effect of preventing ice from falling downward from the gap.

With reference to fig. 11 and 12, a structure for preventing erroneous assembly of the upper freezer compartment container 42 will be described. Fig. 11 is a plan view illustrating a structure for preventing erroneous assembly with respect to an upper-stage freezer compartment 42 provided in an upper-stage freezer compartment 4 of a refrigerator 1 according to the present invention. Fig. 12 is a side view illustrating a structure for preventing erroneous assembly with respect to an upper-stage freezer compartment container 42 provided in an upper-stage freezer compartment 4 of the refrigerator 1 of the present invention.

In the ice making compartment door 3a and the upper freezer compartment door 4a, since the components such as the inner plates 36 and 46 and the movable rails 37 and 47 are shared, it is considered that the upper freezer compartment container 42 is erroneously attached to the fixed rail 39 of the ice making compartment 3.

In order to prevent such erroneous assembly, when the upper freezer compartment container 42 is to be assembled to the ice making compartment 3, the rear end 421 of the upper freezer compartment container 42 is brought into contact with the ice making machine 31, and the upper freezer door 4a cannot be closed. Therefore, the uppermost portion of the rear end 421 of the upper freezer container 42 is located at a position higher than the lowermost portion of the ice maker 31.

The fixing portions (mounting portions) 361, 461 that fix the movable rails 37, 47 (see fig. 5 and 6) will be described with reference to fig. 13. Fig. 13 is a diagram showing the characteristics of the fixed parts 361 and 461 of the movable rails 37 and 47, with respect to the ice making compartment door 3a and the upper freezer compartment door 4a of the refrigerator 1 of the present invention.

In the present embodiment, the inner plate 36 of the ice making compartment door 3a and the inner plate 46 of the upper freezer compartment door 4a are shared. In this case, when the movable rail 47 is used as the inner panel 36 of the ice making compartment door 3a, the fixing portion 461 for fixing the movable rail 47 (see fig. 5 and 6) is not used in the inner panel 36. When the movable rails 37, 47 are fastened to the inner plates 36, 46 by screws, if unused screw holes penetrate the inner plates 36, 46, the front and rear sides of the inner plates 36, 46 communicate through the screw holes, which is not recommended.

In the present embodiment, the fixing portions 361, 461 are protruding portions, and screw holes are formed in the protruding portions, whereby the screw holes do not penetrate the front and rear sides of the inner plates 36, 46. This prevents the front and rear sides of the inner plates 36, 46 from communicating with each other through unused screw holes.

In the above-described embodiment, the ice making compartment door 3a and the upper freezer compartment door 4a adjacent in the left-right direction are described, but the present invention can be applied to the lower freezer compartment door 5a and the vegetable compartment door 6a adjacent in the up-down direction.
