FIG. 2 is a perspective view showing a refrigerator compartment door according to the first embodiment.
As shown in FIG. 2, the refrigerating chamber door 11A includes, for example, an outer shell member 50 and a gasket 55. The outer member 50 is formed in a box shape. The "box shape" as used herein also includes a flat box shape. The outer member 50 has, for example, a frame body 51, a front plate 52 (see FIG. 1), and a rear member 53.
On the inner surface side of the refrigerating chamber door 11A, the upper cases 56A and 56Bc (door container, upper door container), the middle case 62 (door container, middle door container, lower door container), and the lower case 63 (door container, The lower door container) is detachably attached.

The frame body 51 is formed in a rectangular frame shape. The frame body 51 includes an upper side member 51a, a lower side member 51b, a left side member 51c, and a right side member 51d. The upper side member 51a has a plate shape along the width direction and the depth direction, and forms the upper surface of the refrigerator compartment door 11A. The lower side member 51b has a plate shape along the width direction and the depth direction, and forms the lower surface of the refrigerator compartment door 11A. The left side member 51c has a plate shape along the vertical direction and the depth direction, and forms the left side surface of the refrigerator compartment door 11A. The right side member 51d has a plate shape along the vertical direction and the depth direction, and forms the right side surface of the refrigerator compartment door 11A. The frame body 51 is formed by combining the upper side member 51a, the lower side member 51b, the left side member 51c, and the right side member 51d with each other. The frame body 51 is made of, for example, a synthetic resin.

The front plate 52 (see FIG. 1) is attached to the frame 51 and is located at the front end of the refrigerator compartment door 11A. The front plate 52 is a plate member along the vertical direction and the horizontal direction, and forms the front surface of the refrigerator compartment door 11A. The front plate 52 is, for example, a glass plate. However, the front plate 52 is not limited to the glass plate, and may be formed of a synthetic resin or another material.
The front plate 52 may be a flat plate or a curved plate. Hereinafter, the front plate 52 will be described with an example of a flat plate.

The rear member 53 is attached to the frame 51 from the side opposite to the front plate 52, and is located at the rear end of the refrigerator compartment door 11A. The outer shape of the rear surface member 53 when viewed from the −Y direction is rectangular along the frame body 51. The rear surface member 53 forms the rear surface, that is, the inner surface portion of the refrigerator compartment door 11A. The rear surface member 53 is made of, for example, a synthetic resin.
The rear surface member 53 has flat flat portions 53a and 53b along the front plate 52, and ribs 61 protruding rearward from the flat portions 53a and 53b. In the example shown in FIG. 3, the flat portions 53a and 53b are parallel to the front plate 52.
The rib 61 projects in the + Y direction toward the refrigerating chamber 27A (storage chamber) from the frame 51 and the flat portions 53a and 53b in a state where the refrigerating chamber door 11A is closed with respect to the housing 10.
In the present specification, the "rib" is a name for convenience of explanation, broadly means a portion protruding rearward from the rear surface member 53, and is not limited to a specific shape or action.

The rib 61 includes, for example, an annular rib group that is one size smaller than the outer shape of the frame body 51. The term "ring" as used herein is not limited to the case where the entire circumference is completely continuous, but also includes the case where a notch or the like is provided and a part is interrupted.
The annular rib group in the rib 61 includes a rib 61F extending in the horizontal direction along the upper side member 51a, a rib 61G extending in the horizontal direction along the lower side member 51b, and a rib extending in the vertical direction along the left side member 51c. Examples include the 61C and the rib 61A extending in the vertical direction along the right side member 51d. The ribs 61F and 61G have the same length in the width direction. The lengths of the ribs 61C and 61A in the vertical direction are equal to each other.
The rib 61 has, in addition to the annular rib group, a rib 61B extending in the vertical direction between the ribs 61A and 61C in the lateral width direction. The rib 61B extends in the −Z direction from the same position as the upper ends of the ribs 61A and 61C, but the length of the rib 61B is shorter than that of the ribs 61A and 61C. For example, in the example shown in FIGS. 3 and 4, the length of the rib 61B is about two-fifths of the total length of each of the ribs 61A and 61C.
The rib 61 projects relatively large rearward (+ Y direction). For example, the amount of protrusion of the rib 61 to the rear is more than half the thickness of the outer member 50 excluding the rib 61 in the depth direction. In the present embodiment, the amount of protrusion of the rib 61 is larger than the thickness of the outer member 50 excluding the rib 61 in the depth direction.

Although not particularly shown, the space between the rear member 53 and the front plate 52 and the inside of the convex shape of the rib 61 are filled with an effervescent heat insulating material.
The above-mentioned annular rib group in the rib 61 is mainly provided to prevent the cold air in the refrigerating chamber 27A from escaping from the gap between the refrigerating chamber door 11A and the housing 10.

The gasket 55 is provided to seal the refrigerating chamber 27A so that the cold air in the refrigerating chamber 27A does not leak to the outside from between the refrigerating chamber door 11A and the housing 10 when the refrigerating chamber door 11A is closed. Has been done.
The gasket 55 is attached to the rear member 53 in an annular shape surrounding the outer peripheral side of the rib 61. The method of attaching the gasket 55 is not particularly limited. For example, the gasket 55 may be attached by uneven fitting between the mounting convex portion provided on the gasket 55 and the mounting concave portion provided on the rear surface member 53.

Here, the detailed configuration of the rear surface member 53 will be described.
3 and 4 are perspective views showing the rear member 53 of the refrigerator compartment door according to the first embodiment. 3 and 4 differ only in the direction of the perspective. FIG. 5 is a cross-sectional view taken along the line F5-F5 in FIG. FIG. 6 is a cross-sectional view taken along the line F6-F6 in FIG. FIG. 7 is a cross-sectional view taken along the line F7-F7 in FIG.

As shown in FIGS. 3 and 4, in the rear surface member 53, the flat portion 53a of the refrigerating chamber door 11A is formed in a range of about two-thirds from the upper end of the rear surface member 53. The flat portion 53b is located slightly on the + Y direction side of the flat portion 53a. The flat portion 53b is connected at the lower end of the flat portion 53a via a stepped portion.

As shown in FIG. 3, the rib 61A projects in the + Y direction from the end of the flat portion 53a in the + X direction. The rib 61A extends from the rib 61F to the position of the rib 61G in the vertical direction.
The tip portion of the rib 61A in the protruding direction includes a first tip portion 61a, a second tip portion 61c, and a third tip portion 61e from the upper side to the lower side.
The protrusion heights of the first tip portion 61a and the third tip portion 61e from the flat portion 53a are substantially equal to each other. The protruding height of the second tip portion 61c from the flat portion 53a is lower than that of either the first tip portion 61a or the third tip portion 61e. Therefore, a step portion 61b is formed between the first tip portion 61a and the second tip portion 61c. A step portion 61d is formed between the third tip portion 61e and the second tip portion 61c.

As shown in FIG. 3, the side surface S of the rib 61A on the −X direction side is a plane substantially orthogonal to the width direction. A step portion 53c and a rail portion 64 are provided on the side surface S.

The side surface of the step portion 53c in the −X direction is substantially parallel to the side surface S. The height of protrusion of the step portion 53c from the side surface S in the −X direction is not particularly limited. For example, the protruding height of the step portion 53c from the side surface S in the −X direction may slightly exceed the protruding height of the rail portion 64 described later in the −X direction. In this case, the side surface in the −X direction of the step portion 53c approaches the side surface in the + X direction of the upper case 56A, which will be described later, and can function as a guide surface in the lateral width direction of the upper case 56A.
As shown in FIG. 5, the end surface 53cy of the step portion 53c in the + Y direction is a plane orthogonal to the depth direction and extending in the vertical direction.
The upper end of the step portion 53c is connected to the lower surface 61g of the rib 61F. The lower end of the step portion 53c extends in the −Z direction to a position slightly exceeding the step portion 61b.

As shown in FIG. 3, the rail portion 64 is a protrusion that protrudes from the side surface S in the −X direction and extends in an elongated line in the vertical direction as a whole. When the upper case 56A, which will be described later, is moved in the vertical direction, the rail portion 64 guides the upper case 56A in the vertical direction with the position in the depth direction restricted.
As shown in FIG. 5, the rail portion 64 extends parallel to the end surface 53cy with a gap between the rail portion 64 and the end surface 53cy of the step portion 53c. A gap G1 is formed between the upper end of the rail portion 64 and the lower surface 61 g of the rib 61F.
The lower end of the rail portion 64 extends to substantially the same position as the step portion 61b.
The rail portion 64 has a first rail portion 64a and a second rail portion 64b from the bottom to the top.

The first rail portion 64a guides the vertical movement of the upper case 56A, which will be described later, and regulates the vertical movement position of the upper case 56A in multiple stages.

The second guide 64d forms a side surface of the rail portion 64 in the + Y direction. The second guide 64d has a flat plate shape that protrudes from the side surface S in the −X direction and extends in the vertical direction. The second guide 64d is parallel to the first guide 64c. The second guide 64d extends to the second rail portion 64b like the first guide 64c.
The tips of the first guide 64c and the second guide 64d are located on the same plane orthogonal to the depth direction.

The plurality of locking plates 64e have a plate shape extending in the depth direction between the first guide 64c and the second guide 64d and projecting from the side surface S in the −X direction. The plurality of locking plates 64e are provided apart from each other in the vertical direction from the lower ends of the first guide 64c and the second guide 64d to the upper end of the first rail portion 64a. The pitch of each locking plate 64e in the vertical direction does not have to be constant, but is constant in the example shown in FIG.
The size of the pitch Δ is not particularly limited, and may be, for example, 10 mm or more and 70 mm or less, and more preferably 10 mm or more and 22 mm or less.
In the example shown in FIG. 5, six locking plates 64e are arranged. When distinguishing each locking plate 64e, it is described as locking plates 64e1, 64e2, ..., 64e6 from the lower side to the upper side.
The tip of each locking plate 64e in the protruding direction is located on the same plane as the tip of the first guide 64c and the second guide 64d.

The upper end plate 64g has a plate shape similar to that of the plurality of locking plates 64e, except that the upper surface is connected to the lower end of the second rail portion 64b. The upper end plate 64g is arranged between the first guide 64c and the second guide 64d, away from the uppermost locking plate 64e. In the example shown in FIG. 5, the upper end plate 64g is arranged at a position separated from the locking plate 64e6 by the pitch Δ in the + Z direction.

The plurality of inclined ribs 64f have a plate shape extending parallel to the first guide 64c and the second guide 64d from the lower surface of each locking plate 64e except the locking plate 64e1 and the lower surface of the upper end plate 64g toward the side surface S, respectively. Is. As shown in FIG. 6, the shape of each inclined rib 64f as seen from the −Y direction is a side surface of each locking plate 64e except the locking plate 64e1 and the upper end plate 64g from each tip in the −X direction in the −Z direction. It has a triangular shape that slopes toward S.
The lower end of each inclined rib 64f is located in the middle of the pitch Δ. The inclination angle φ of each inclined rib 64f measured counterclockwise with respect to the horizontal plane is, for example, 45 degrees or more and 80 degrees or less.
The number of inclined ribs 64f provided on the same lower surface in the depth direction is not particularly limited as long as it is 1 or more. In the example shown in FIG. 5, the number of inclined ribs 64f provided on the same lower surface is two.

With such a configuration, a plurality of convex portions are arranged vertically on the inside of the first rail portion 64a at a pitch Δ from the lower side to the upper side when viewed from the −Y direction. The plurality of convex portions are formed by an inclined surface 64j formed by the inclined rib 64f, a tip surface of the locking plate 64e, and a locking surface 64i formed on the upper surface of the locking plate 64e and extending in the horizontal direction. Relative concave portions are formed between the convex portions protruding from the side surface S in the −X direction. Therefore, inside the first rail portion 64a, a sawtooth-shaped uneven structure in which the inclined surface 64j faces downward is formed.
Each locking surface 64i of the plurality of locking plates 64e locks the first locking portion 70, which will be described later, from below.
The inclined surface 64j at the lower end of the plurality of inclined ribs 64f is inclined so that the first locking portion 70 can be pressed toward the upper case 56A as the first locking portion 70 described later moves upward from the locking surface 64i. ..
The plurality of locking plates 64e and the plurality of inclined ribs 64f provided on the ribs 61A forming the inner surface portion of the refrigerating chamber door 11A have a second engaging surface having a plurality of locking surfaces 64i and a plurality of inclined surfaces 64j. This is an example of a stop.
The plurality of locking surfaces may be flat surfaces or curved surfaces as long as the locking member 73 described later can be locked. The contact form of the portion where the locking member 73 is locked on the plurality of locking surfaces may be surface contact, line contact, or point contact as long as the locking member 73 can be locked.
The plurality of inclined surfaces may be flat surfaces or curved surfaces as long as the locking member 73 described later is slidable. The contact form of the portion where the locking member 73 slides on the plurality of inclined surfaces may be any of surface contact, line contact, and point contact as long as the locking member 73 can slide.

As shown in FIG. 5, the second rail portion 64b is formed between the first guide 64c and the second guide 64d extending in the + Z direction from the first rail portion 64a and the first guide 64c and the second guide 64d. It has an intermediate rib 64h extending in the + Z direction.
The intermediate rib 64h has a flat plate shape parallel to the first guide 64c and the second guide 64d. The vertical length of the intermediate rib 64h is equal to the length from the upper end plate 64g to the tips of the first guide 64c and the second guide 64d. The lower end of the intermediate rib 64h is connected to the upper surface of the upper end plate 64g. The height of the intermediate rib 64h in the −X direction is equal to the height of the first guide 64c and the second guide 64d in the −X direction.
The number of intermediate ribs 64h is not particularly limited as long as it is 1 or more. In the example shown in FIG. 5, the number of intermediate ribs 64h is one.

The arrangement position of the rib 61B in the horizontal width direction is appropriately set according to the widths of the upper cases 56A and 56B in the horizontal width direction. In the present embodiment, as an example, since the upper cases 56A and 56B have the same width, the rib 61B is arranged at a position that bisects the distance between the ribs 61A and 61C in the lateral width direction.

As shown in FIG. 3, a rail portion 64, a step portion 53c, and a first stopper 53d similar to those in the rib 61A are provided on the side surface Sm of the rib 61B in the −X direction.
As shown in FIG. 4, a rail portion 64, a step portion 53c, and a first stopper 53d similar to those in the rib 61C are provided on the side surface Sp in the + X direction of the rib 61B.

The case body 57 accommodates the stored items stored in the refrigerating chamber 27A.
The elevating table 67 detachably supports the case main body 57, and can move vertically along each rail portion 64 between the ribs 61A and 61B while supporting the case main body 57. The position of the lift 67 is fixed in the vertical direction by locking the lift 67 to any of a plurality of locking plates 64e in each rail portion 64.

The case body 57 is a box-shaped container that opens upward, and is detachably placed on the elevating table 67. The case body 57 does not have to be plane-symmetrical with respect to a plane orthogonal to the width direction, but in the following, it is plane-symmetrical as an example. Therefore, the member arranged on the side surface on the −X direction side is also arranged on the side surface on the + X direction side.
As shown in FIG. 9, the case body 57 has a bottom surface portion 57a on a horizontally arranged flat plate, and a first wall portion 57b, a second wall portion 57c, and a first side wall formed on an outer edge portion of the bottom surface portion 57a.

The first side wall portion 57f is a peripheral edge in the + X direction and the −X direction on the bottom surface portion 57a, and extends in the + Z direction and the −Z direction from a wide portion on the + Y direction side. However, each of the first side wall portions 57f extending in the −Z direction has a length that covers the bottom plate portion of the lifting platform 67, which will be described later, from the + X direction and the −X direction. The + Y direction ends of each first side wall portion 57f are smoothly connected to the first wall portion 57b.
Each of the first side wall portions 57f in the present embodiment is composed of a curved surface that bulges outward in the lateral width direction from the first wall portion 57b toward the −Y direction.

The second side wall portion 57d is a peripheral edge in the + X direction and the −X direction on the bottom surface portion 57a, and extends in the + Z direction from a narrow portion on the −Y direction side, respectively.

In the present embodiment, the locking projection 57h is formed at a position facing the rail portion 64 in the lateral width direction when the upper case 56A is mounted. However, the protrusion height of the locking projection 57h from the second side wall portion 57d of the locking projection 57h is such that the distance in the lateral width direction of each locking projection 57h is the distance in the lateral width direction between the rail portions 64 of the ribs 61A and 61B. It is the height that becomes narrower. Therefore, there is no possibility that the rail portion 64 and the locking projection 57h come into contact with each other when the upper case 56A is attached and when the upper case 56A is moved in the vertical direction.

A flange portion 57j extending in the −Y direction is formed at the upper end of the second wall portion 57c. The height and thickness of the flange portion 57j are the same as those of the flange portion 57g.

The case body 57 is made of, for example, a synthetic resin. The case body 57 may be made of a transparent material, a translucent material or an opaque material. When the case body 57 is made of a transparent material or a translucent material, it is more preferable because the inside of the case body 57 can be seen from the outside. The case body 57 may be partially made of a transparent material and the other may be made of a translucent material or an opaque material. The portion formed of the translucent material or the opaque material may be a portion that covers the elevating platform 67 described later from above or from the outside.

The locking projection 58A is provided at the upper end portion closer to the upper end surface 58h, away from the opening of the guide hole portion 58u in the −Y direction in the depth direction. The vertical distance from the upper end surface 58h of the second side wall portion 58d to the lower end 58Ac of the locking projection 58A is L58A.
In the present embodiment, the sum of L57i and L58A is the vertical direction of the gap G1 between the contact position where the ridge 57i of the raised upper case 56A and the lower surface 61g of the rib 61F abut and the upper end of the rail portion 64. Although it is larger than the distance (hereinafter referred to as the gap distance), L58A is smaller than the gap distance. Therefore, the upper case 56A in which the case body 57 is placed on the elevating table 67 cannot pass through the gap G1 in the + Y direction, but the elevating table 67 alone can pass through the gap G1 in the + Y direction. ..

As shown in FIG. 8, the locking projection 58A includes a plate-shaped portion 58Aa extending in the vertical direction and a plurality of ridges 58Ab protruding in the + Y direction from the surface of the plate-shaped portion 58Aa in the + Y direction and extending in the lateral width direction.

The locking member 73 is inserted from the opening in the + X direction of the first holder 71 toward the opening 71b with the inclined surface 73b as the tip end.
On the outside of the main body 73a protruding from the opening 71b, an urging member 72 (second urging member) indicated by a two-dot chain line is arranged so as to surround the main body 73a. The urging member 72 is a compression coil spring through which the main body portion 73a can be inserted and which can be locked to the bottom plate portion 71a of the first holder 71 from the + X direction.

The urging member 74 is arranged between the locking member 73 inserted into the first holder 71 in the first locking portion 70 and the second holder 75 described later, and the locking member 73 is placed in the −X direction. To urge. In the example shown in FIG. 13, the urging member 74 is a compression coil spring. The inner diameter of the urging member 74 is larger than the outer diameter of the protrusion 73e. The outer diameter of the urging member 74 is such that it can be inserted inside the first holder 71 from the −X direction. The first end portion 74a of the urging member 74 in the −X direction is locked to the + X direction side of the flat plate portion 73c. The second end portion 74b of the urging member 74 in the + X direction is locked inside the second holder 75, which will be described later.

The second holder 75 is fixed to the end of the first holder 71 in the + X direction, and constitutes the end of the first locking portion 70 in the + X direction.
The second holder 75 has a protrusion 75a (first protrusion) and a connecting portion 75f.
The end face 75e of the protrusion 75a in the −X direction is a plane orthogonal to the width direction. The outer shape of the protruding portion 75a in the + X direction is a chevron shape having a top portion 75b in the protruding direction when viewed from the + Z direction. The top portion 75b may be a plane parallel to the end surface 75e, or may be a curved surface having a convex arc shape when viewed from the + Z direction.
In the example shown in FIG. 10, the chevron shape of the protrusion 75a is an isosceles triangle, and the top 75b is a curved surface having a convex arc shape.
The inclination of the protrusion 75a with respect to the end surface 75e is not particularly limited as long as it is equal to or greater than the inclination of the protrusion 59e. In the example shown in FIG. 10, the inclination of the protrusion 75a is substantially equal to the inclination of the protrusion 59e.

As shown in FIG. 14, a recess 75d into which the second end portion 74b of the urging member 74 can be inserted is formed in the central portion of the end surface 75e. The second end portion 74b is locked to the protrusion portion 75a in the recess 75d from the + X direction.

The connecting portion 75f is in the shape of a piece protruding in the −X direction from both ends of the protruding portion 75a in the depth direction. At the end of each connecting portion 75f in the protruding direction, a locking portion 75g for locking with the locking projection 71e is provided in a state where the end surface 75e is in contact with the end surface of the first holder 71 in the + X direction.

As shown in FIG. 13, the first locking portion 70 in the assembled state has the urging member 74, the locking member 73, and the locking member 73 in the internal space formed by connecting the protrusion 75a and the first holder 71. Is housed, and a part of the main body portion 73a protrudes from the opening 71b in the −X direction. The flat plate portion 73c is urged by the urging member 74 and is in contact with the inner surface of the bottom plate portion 71a on the + X direction side. At this time, the amount of protrusion of the main body 73a is maximum.
As shown in FIGS. 10 and 13, when the operating member 59 is arranged at the locking position, the top portion 75b of the protrusion 75a of the first locking portion 70 is in contact with the top portion 59f of the pressing member 59d. The first holder 71 is urged in the + X direction by the urging member 72 arranged between the second side wall portion 58d and the bottom plate portion 71a. Therefore, the arrangement position of the first locking portion 70 in the lateral width direction at the locking position is positioned by the top portion 59f. In the following, such an arrangement position of the first locking portion 70 will be referred to as a locking position of the first locking portion 70.

The main body portion 73a of the first locking portion 70 at the locking position is inserted into the guide hole portion 58u and extends to the outside of the second side wall portion 58d. The guide hole portion 58u is formed with a rectangular opening through which the main body portion 73a is inserted and a U-shaped groove into which each guide rib 73d can slide in the lateral width direction. By engaging the guide ribs 73d and the U-shaped groove of the guide hole portion 58u so as to be slidable in the lateral width direction, the position of the moving main body portion 73a in the depth direction is stabilized.

In the present embodiment, the urging member 74 and the locking member 73 are arranged in series substantially coaxially, and the locking member 73 protruding from the first holder 71 is inserted inside the urging member 72. .. Therefore, the urging member 72, the locking member 73, the first holder 71, and the urging member 72 are arranged substantially coaxially with each other.
As described above, in the present embodiment, the urging member 72 and the first locking portion 70 are arranged substantially coaxially. Therefore, for example, the urging member 72 and the constituent members of the first locking portion 70. Space can be saved as compared with the case where the and are arranged in parallel in at least one of the depth direction and the vertical direction.

Here, the operation of the first locking portion 70 and the operating member 59 will be described.
15 and 16 are cross-sectional views illustrating the operation of the first locking portion in the refrigerator of the first embodiment.

As described above, at the locking position of the first locking portion 70, the positions of the first holder 71 and the second holder 75 in the lateral width direction are fixed. On the other hand, the locking member 73 is urged by the urging member 74 inside the first holder 71 and the second holder 75, but can move in the + X direction. Therefore, when the tip of the locking member 73 in the −X direction is pressed in the + X direction with a force larger than the urging force of the urging member 74, the locking member 73 moves in the + X direction.
In the present embodiment, as shown in FIG. 15, the locking member 73 is movable so that its tip is retracted into the guide hole portion 58u.

When the operating member 59 is moved to the unlocked position by the user, each pressing member 59d moves in the + Y direction as shown by the alternate long and short dash line in FIG. At this time, in the operating member 59, the guide members 59c arranged at two points symmetrical with respect to the plane Ss are guided in the depth direction by the first guide portion 58n. Further, the operating member 59 moves in the + Y direction against the urging force of the urging members 77 arranged at two positions symmetrical with respect to the plane Ss. The urging force of each urging member 77 is uniform in the lateral width direction.
Therefore, the operating member 59 moves in parallel in the + Y direction even if the position where the user operates the operating portion 59a varies in the groove portion 59h in the lateral width direction. As a result, the pressing members 59d move in the + Y direction in synchronization with each other.
When each pressing member 59d moves in the + Y direction, the first locking portion 70 urged toward the pressing member 59d by the urging member 72 moves toward the pressing member 59d, respectively. The urging member 72 extends between the second side wall portion 58d and the bottom plate portion 71a.
When the pressing member 59d retracts from the opening of the second guide portion 58t, as shown in FIG. 16, each of the first locking portions 70 moves toward the flat plate portion 59g at the same time, and the top portion 75b becomes the flat plate portion 59g. Contact.
As a result, in the present embodiment, the locking member 73 protruding from the first holder 71 also translates in the + Y direction and retracts inside the guide hole portion 58u. That is, the locking member 73 retracts inside the guide hole portion 58u in a state of being urged toward the bottom plate portion 71a by the urging member 74.
When the operating member 59 moves to the unlocked position in this way, a state is obtained in which the first locking portion 70 moves and does not pop out from the guide hole portion 58u of each locking member 73. In this state, the locking member 73 of each first locking portion 70 cannot be locked to the second locking portion, so that the position of the first locking portion 70 corresponding to the unlocking position of the operating member 59 is locked. Called an impossible position.
In the present embodiment, at the unlockable position of the first engaging portion 70, the locking member 73 retracts inside the guide hole portion 58u, but if the first engaging portion 70 cannot be contacted with the second locking portion, the second locking member 73 is locked. Since it cannot be locked to the portion, the locking member 73 may protrude from the guide hole portion 58u.

When the user releases the operation unit 59a, the operation member 59 moves in the −Y direction due to the urging force of the urging member 77, so that the operation member 59 and each of the first locking portions 70 are in their respective locking positions. Return to. At this time, the operating member 59 that moves by receiving the urging force from the urging member 77 hits the vibration absorbing member 78 without colliding with the member of the elevating platform main body 58 such as the tip wall portion 58w. The kinetic energy of the operating member 59 is absorbed by the vibration absorbing material 78, and the operating member 59 stops at the locking position. Therefore, the striking sound due to the impact of the operating member 59 is reduced.
A certain amount of impact force is transmitted to the elevating table main body 58 through the vibration absorbing material 78. In the present embodiment, the lifting platform main body 58 is subjected to an external force by the expansion and contraction of the urging member 77 and the operation member 59 is hit. And, it is provided at a position facing each other in the direction of the external force. Therefore, by screwing the lower cover 60 with the fixing bosses 58r and 58q, a reinforcing structure that efficiently resists an external force can be obtained. As a result, even if an external force such as an impact force is transmitted to the elevator body 58 to some extent, the vibration is suppressed, so that a stable operation feeling can be obtained.

In the present embodiment, the locking member 73 projects to the outside of the guide hole portion 58u at the locking position, and retracts to the inside of the guide hole portion 58u depending on the external force acting on the locking member 73. Similarly, when the operating member 59 moves to the unlocked position, the entire first locking portion 70 moves in parallel and moves to the unlockable position.

Next, the locking structure when the upper case 56A is attached to the refrigerator compartment door 11A will be described.
FIG. 17 is a cross-sectional view showing a locking structure of the door container according to the first embodiment.
The solid upper case 56A shown in FIG. 17 is mounted on the fifth locking plate 64e5 from the bottom by locking it from above.
Since the operating member 59 is in the locking position, the main body portion 73a of the locking member 73 projects outside the second side wall portion 58d. The main body portion 73a is inserted inside a relative recess surrounded by the first rail portion 64a, the locking plate 64e5, the second rail portion 64b, and the locking plate 64e6.
Since the width of the tip of the main body 73a in the depth direction is slightly narrower than the distance between the first rail portion 64a and the second rail portion 64b, when the main body portion 73a is inserted into the recess, the upper case 56A is moved in the depth direction. Is also in a locked state.
The locking projection 58A and the guide plate 58B sandwich the rail portion 64. The lower surface 73f of the main body 73a is pressed against the locking surface 64i of the locking plate 64e5 by gravity.
Since the center of gravity of the upper case 56A is in the + Y direction with respect to the rail portion 64, the upper end portion of the locking projection 58A presses the second rail portion 64 in the + Y direction.
The upper case 56A at the time of mounting cannot be pulled out in the + Y direction, and the lowering in the −Z direction is suppressed.

In the present embodiment, the upper case 56A can be moved by the user performing the push-up operation and the unlocking operation described below.
The push-up operation is an operation in which the user applies a force to the upper case 56A in the + Z direction to move the upper case 56A in the + Z direction. The user may apply a force to any part of the upper case 56A, but when the user puts his / her hand on the lower surface of the elevating table 67 and pushes up the upper case 56A, an upward force is applied near the locking position of the first locking portion 70. Since it is added, smoother operation is possible.
When pushing up the lower surface of the elevating table 67, for example, as compared with the case where the upper end of the upper case 56A is gripped and lifted, it is easier to apply force, and even a short user can easily move the upper case 56A.
In the locking structure of the present embodiment, there is no member that locks the upper case 56A from above. Therefore, when the user applies an upward force to the upper case 56A, the upper case 56A can rise along the rail portion 64. Is. That is, it is lifted by the user and the locking member 73 moves to the upper side of the locking plate 64e5.

When the locking member 73 rises to the position where the first guide 64c is arranged, the inclined surface 73b and the first guide 64c come into contact with each other, and the locking member 73 is moved inward by the horizontal component of the reaction from the first guide 64c. Be pushed in.
When the locking member 73 reaches the recess on the upper side of the locking plate 64e6, the reaction of pushing the locking member 73 from the rail portion 64 disappears, so that the locking member 73 projects to the outside of the second side wall portion 58d. At this time, if the user releases the hand and stops the pushing-up operation, the locking member 73 is locked to the locking plate 64e6 from above.
By such a push-up operation, the user can move the upper case 56A in the + Z direction and lock the upper case 56A on the upper locking plate 64e.

In the push-up operation, the upper case 56A can be locked to the upper side, but the upper case 56A cannot be lowered. Therefore, for example, even if the hand is removed before reaching the upper side of the upper locking plate 64e, the hand is surely locked on the nearest lower locking plate 64e. Therefore, in the push-up operation, the upper case 56A is prevented from falling.

The locking release operation is an operation for forcibly releasing the locking in the vertical direction by the locking member 73.
In this operation, the user operates the operation member 59 to move the operation member 59 to the unlocked position. For example, the user manually holds the operation unit 59a and the lower end of the first wall portion 58b in the depth direction to move the operation member 59 in the + Y direction. In the present embodiment, when the distance between the operating portion 59a and the first wall portion 58b is minimized, the operating member 59 moves to the unlocked position.
At the unlocking position, each locking member 73 retracts inside the second side wall portion 58d, so that the locking by the locking member 73 is released. The user can freely move the upper case 56A as long as it is within the movable range of the upper case 56A. For example, the user can move the upper case 56A in the vertical direction while holding the operation portion 59a and the lower end of the first wall portion 58b with one hand.
When the user releases the grip between the operating portion 59a and the lower end of the first wall portion 58b at the moving destination, the locking member 73 protrudes to the outside of the second side wall portion 58d due to the urging force of the urging member 77. The locking member 73 projects into a recess on the nearest lower locking plate 64e. By releasing the hand in this state, the locking member 73 is locked on the lower locking plate 64e closest to the moving destination.
By such an unlocking operation, the user can lock the upper case 56A on arbitrary locking plates 64e facing each other in the horizontal direction. That is, the upper case 56A can be moved in the vertical direction and the moving position can be fixed in units of pitch Δ.

According to the upper case 56A of the present embodiment, the user can move the upper case 56A in front of the upper case 56A by a simple operation with one hand in either the push-up operation or the unlocking operation.

Here, the movable range of the upper case 56A will be described.
The lowermost lowering position of the upper case 56A is a position where the lower end of the locking projection 58A is locked to the first stopper 53d from above. In the example shown in FIG. 17, the upper case 56AL in the lowermost lowering position is the same as the state in which the locking member 73 is locked to the lowermost locking plate 64e1. However, if the first stopper 53d is arranged further down, the lowest descending position can be set further down.

In the present embodiment, the second rail portion 64b is formed on the upper portion of the rail portion 64. Since the second rail portion 64b is not formed with a recess into which the locking member 73 can enter, the upper case 56A can be locked only up to the position of the locking plate 64e6.
Since the rail portion 64 is sandwiched between the locking projection 58A and the guide plate 58B even above the locking plate 64e6, it can move up and down along the rail portion 64.
In the present embodiment, the upper case 56A can be raised until the upper end of the upper case 56A abuts on the lower surface 61g of the rib 61F, like the upper case 56AH indicated by the alternate long and short dash line. Specifically, the position where the ridge 57i of the case body 57 abuts on the lower surface 61 g is the highest rising position.
In the present embodiment, the sum (first distance) of L57i and L58A is larger than the above-mentioned gap distance in the gap G1, so that the lower end of the locking projection 58A and the upper end of the rail portion 64 are at the highest ascending position. The portions overlap each other when viewed from the −Y direction. Therefore, the upper case 56A cannot be pulled out in the + Y direction.
According to the present embodiment, when the user raises the upper case 56A to which the case body 57 is attached, it is possible to prevent the upper case 56A from coming off due to the momentum or momentum at the time of raising.

As described above, the gap G1 is an opening for preventing the upper case 56A from coming off. The lower surface 61 g of the rib 61F is an example of a second stopper that regulates the ascending position of the upper case 56A and prevents the upper case 56A from coming off from the upper side of the rail portion 64.
The ridge 57i is an example of a first contact portion that can come into contact with the second stopper when mounted on the elevating table 67.

It is preferable that the upper case 56A can be removed from the refrigerator compartment door 11A for the purpose of cleaning, for example. In the present embodiment, the side surface of the case body 57 is not provided with a protrusion that can be locked from the −Y direction side of the rail portion 64. Therefore, if the case main body 57 is moved in the + Z direction while the locking projection 57h exits the concave groove 58j, the case main body 57 can be removed from the elevating table 67. The removed case body 57 can be taken out in the + Y direction between the rail portions 64 facing each other or through the gap G1.
In this way, it can be attached to and detached from the elevating table 67 without removing the elevating table 67. Therefore, since the stored items come into direct contact with each other, the case body 57 alone, which is highly necessary for cleaning, can be easily cleaned. Since the case body 57 is lighter than the lift 67, the load on the user due to attachment / detachment is reduced. Since it is not necessary to move the elevating table 67 when removing the case body 57, it is not necessary to perform an operation of returning the case body 57 to the position before removal after mounting the case body 57.
Since only the case body 57 can be removed, the stored items in the case body 57 can be easily taken out of the refrigerator.

In the lift 67 from which the case body 57 has been removed, L58A (second distance) is larger than the above-mentioned gap distance. Therefore, if the lifting platform 67 is raised to at least the uppermost position of the lifting platform 67 where the upper end surface 58g of the lifting platform 67 abuts on the lower surface 61g, the locking projection 58A can pass through the gap G1 in the + Y direction.
In this way, the elevating table 67 from which the case body 57 has been removed can be taken out in the + Y direction through the gap G1 by raising it by the above-mentioned pushing-up operation or unlocking operation.
The upper end surface 58h is an example of a second contact portion that can come into contact with the second stopper in the moving direction along the rail portion when the container body is removed.

The position of the lift 67 can be changed in the vertical direction with the case body 57 removed. Therefore, when changing the locking position of the upper case 56A, if the case body 57 is taken out of the refrigerator 1A together with the stored items and then the lift 67 is moved, the load on the user is reduced.

Next, the middle case 62 will be described.
As shown in FIG. 2, the middle case 62 can be mounted in the space between the upper cases 56A and 56B and the lower case 63 and sandwiched between the ribs 61A and 61C.
By locking the middle case 62 to any of the locking projections 66A and 66B shown in FIGS. 3 and 4, the mounting position in the vertical direction can be changed.
FIG. 18 is a perspective view showing an example of a door container (middle door container) according to the first embodiment.
As shown in FIG. 18, the middle case 62 is formed in a box shape with an open upper part.
The middle case 62 has a width dimension at the end on the −Y direction side that can be inserted between the ribs 61A and 61C in the vicinity of the ribs 61A and 61C, and the vertical dimension depending on the type of the stored material. Except for the differences, it has substantially the same configuration as the case body 57 of the upper case 56A.
The middle case 62 has a bottom surface portion 62a, a first wall portion 57b, a second wall portion 57c, a first side wall portion 57f, a step portion 57e, and a second side wall portion 57d instead of the bottom surface portion 57a, the first wall portion 57b, and the second side wall portion 57d. A wall portion 62b, a second wall portion 62c, a first side wall portion 62f, a step portion 57e, and a second side wall portion 62d are provided. Hereinafter, the points different from the case main body 57 will be mainly described.

The bottom surface portion 62a is the same as the bottom surface portion 57a except that the dimension in the width direction is longer.
The first wall portion 62b is the same as the first wall portion 57b except that it extends from the bottom surface portion 62a only in the + Z direction and is lower than the first wall portion 57b.
The second wall portion 62c is the same as the second wall portion 57c except that it does not have the flange portion 57j and the ridge 57i and has the same height as the first wall portion 62b.
The first side wall portion 62f is the same as the first side wall portion 57f except that it extends from the bottom surface portion 62a only in the + Z direction and has the same height as the first wall portion 62b.
The step portion 62e is the same as the step portion 57e except that it has the same height as the first wall portion 62b.

The second side wall portion 62d has a flange portion 62g and a locking projection 62h instead of the flange portion 57g and the locking projection 57h, and the second side wall portion 57d has the same height as the first wall portion 62b. Is similar to.
The flange portion 62g extends from the upper end of the second side wall portion 62d to the outside of the middle case 62 in the lateral width direction, and can be locked to the upper end of the locking projection 66A or the locking projection 66B from above. That is, the middle stage case 62 is arranged at the first position when the flange portion 62g is locked to the locking projection 66A, and is located at the second position δ below the first position when locked to the locking projection 66B. Is placed in.
The locking projection 62h projects from the second side wall portion 62d to the outside of the middle case 62 in the lateral width direction. The locking projection 62h has a width in the depth direction that can be detachably fitted from above into the gaps g2 and g3 of the ribs 61A and 61C. The vertical length of the locking projection 62h is shorter than the vertical gap between the locking projections 66A and 66B.
The locking projection 62h is provided at a position where a slight gap is formed between the second wall portion 62c and the flat portion 53a when fitted into the gap g2 or the gap g3.

The storage may be directly arranged inside the middle case 62, or an internal container for accommodating the storage may be arranged. Examples of the internal container include, for example, a box-shaped container that opens upward and an egg tray that holds eggs upright. In the example shown in FIG. 18, an egg tray 62i is arranged as an internal container.

Next, the lower case 63 will be described.
As shown in FIG. 2, the lower case 63 is below the middle case 62 and can be mounted in the space sandwiched between the ribs 61A and 61C.
The lower case 63 can be detachably arranged on the rib 61G by locking the lower case 63 to the locking projections 65 shown in FIGS. 3 and 4. However, the arrangement position of the lower case 63 at the time of mounting is fixed in the vertical direction.

FIG. 19 is a perspective view showing an example of a door container (lower door container) according to the first embodiment.
The lower case 63 has a first accommodating portion 63A and a second accommodating portion 63B. The first accommodating portion 63A and the second accommodating portion 63B are arranged in parallel in this order in the + Y direction.
The second accommodating portion 63B has a second bottom plate 63a2 mounted on the second plate-shaped portion 61Gb of the rib 61G. The second bottom plate 63a2 is inclined in the same manner as the second plate-shaped portion 61Gb. When the lower case 63 is attached, the −Y direction end of the second bottom plate 63a2 is substantially continuous with the + Y direction end of the first plate-shaped portion 61Ga.
A second wall portion 63c protrudes upward from the + Y direction edge of the second bottom plate 63a2, and a second side wall portion 63d protrudes upward from each end edge in the lateral width direction. The protruding direction of the second wall portion 63c and each second side wall portion 63d is the normal direction of the second bottom plate 63a2.
The end surface 63i of each second side wall portion 63d in the −Y direction extends in the vertical direction. As shown in FIG. 2, when the lower case 63 is mounted, each end face 63i is arranged along the end face 55fy of the locking guide 53f and abuts on the end face 53fy from the + Y direction side.
The second wall portion 63c and each second side wall portion 63d form a recess that opens in the + Z direction between the second wall portion 63c and the flat portion 53b. Therefore, the contents can be accommodated on the first plate-shaped portion 61Ga and the second bottom plate 63a2 in a state of being inclined in the + Y direction according to the inclination of each inclined surface.

On each second side wall portion 63d, a locking projection 63h projects to the outside of the lower case 63 in the lateral width direction. The locking projection 63h has a width in the depth direction that can be detachably fitted from above into each of the concave grooves g4 in the ribs 61A and 61C.

As shown in FIG. 2, the first accommodating portion 63A protrudes in the + Y direction from the rib 61G and the first accommodating portion 63A when mounted.
As shown in FIG. 19, the first accommodating portion 63A has a first bottom plate 63a1 that is inclined in the same manner as the second bottom plate 63a2.
The first wall portion 63b protrudes upward at the end edge in the + Y direction of the first bottom plate 63a1, and the first side wall portion 63f protrudes upward at each end edge in the lateral width direction. The protruding direction of the first wall portion 63b and each first side wall portion 63f is the normal direction of the first bottom plate 63a1.
The −Y direction ends of the first side wall portions 63f are connected to the second side wall portion 63d from the outside, and between the first side wall portion 63f and the second side wall portion 63d, the step portion 63e in the lateral width direction is connected. Is formed.
As shown in FIG. 2, when the lower case 63 is mounted, each step portion 63e abuts on each of the third tip portions 61e of the ribs 61A and 61B from the + Y direction side. The end face 63i is arranged along the end face 55fy of the locking guide 53f, and abuts on the end face 53fy from the −Y direction.
Like the second accommodating portion 63B, the first accommodating portion 63A can accommodate the contained object in a state of being inclined in the + Y direction.

Such a lower case 63 can be mounted between the ribs 61A and 61C by inserting the locking projections 63h into the concave groove g4 from above.

In the refrigerator compartment door 11A of the present embodiment, the vertical arrangement positions of the upper cases 56A and 56B can be changed in multiple stages in Δ units in each movement range. The arrangement position in the vertical direction of the middle case 62 can be changed to two stages, a first position and a second position. The movement pitch Δ of the upper cases 56A and 56B is smaller than the movement pitch δ of the middle case 62.
The relationship between the moving range (5 × Δ) of the upper cases 56A and 56B and the moving range (δ) of the middle case 62 is not particularly limited. In this embodiment, δ is less than 5 × Δ.
The relative arrangement positions of the upper cases 56A and 56B and the moving pitch and range of the middle case 62 when they are moved can be optimized according to the height of the contents. To set.

Hereinafter, examples of arrangement positions of the upper cases 56A and 56B and the middle case 62 will be described based on specific usage examples.
FIG. 20 is a perspective view showing an example of using the door container in the first embodiment. 21 and 22 are cross-sectional views showing an example of using the door container in the first embodiment.
FIG. 20 shows an example of the contents of the refrigerator compartment door 11A and the arrangement positions of the stage cases 56A and 56B and the middle stage case 62 suitable for the arrangement of the contents.

In the example shown in FIG. 20, the egg tray 62i is arranged inside the middle case 62 below the upper case 56B. In this case, since it is sufficient to have a space above the egg tray 62i necessary for taking out the eggs, a large storage space can be secured on the upper case 56B by lowering the upper case 56B. In order to efficiently use this storage space, for example, a milk carton 82 may be arranged in the upper case 56B. When the milk carton 82 is a 1 L paper carton container, the height H2 (see FIG. 21) is about 70 mm.
On the other hand, the space between the ribs 61A and 61B above the middle case 62 is divided into two in the vertical direction according to the arrangement position of the upper case 56A. The middle case 62 may contain a medium-height container, for example, a dressing container 83, and the upper case 56A may contain a 350 mL can 81. For example, the height H3 of the dressing container 83 having an internal volume of 280 mL (see FIG. 21) and the height H4 of the 350 mL can 81 (see FIG. 21) are about 125 mm and about 122 mm, respectively.
By accommodating the higher dressing container 83 in the middle case 62 and the lower 350 mL can 81 in the upper case 56A, the dressing container 83 can be easily taken out.
An example of a container that is preferably stored in the middle case 62 is a 1 L PET bottle containing a liquid seasoning such as soy sauce or mentsuyu. The height of the 1L PET bottle is about 270 mm.

Since the hinge 30 of the refrigerator compartment door 11A of the present embodiment is on the right side, a large centrifugal force acts on the contents arranged in the −X direction in the lateral width direction. From the viewpoint of making it difficult for the contents to fall due to centrifugal force, it is preferable to arrange the higher contents in the + X direction. If there is a concern that the milk carton 82 may fall over, the left and right arrangements described above may be reversed.
The upper cases 56A and 56B, and the middle case 62 may not be arranged for the tall and easily fallen contents. For example, the storage space above the upper cases 56A and 56B at the lowest position, the middle case 62 when the upper cases 56A and 56B are placed at the uppermost position and the middle case 62 at the lowest position, and the upper cases 56A and 56B. The height of the space between them may be such that the 2L PET bottle 84 cannot be accommodated. The height H1 of the 2L PET bottle 84 (see FIG. 21) is about 306 mm.

It is more preferable that the lower case 63 can be arranged with a tall and heavy container. For example, it is more preferable that the lower case 63 can be arranged with a 2L PET bottle 84, a milk carton 82, or the like.

FIG. 21 shows the positional relationship when the upper case 56A is in the uppermost position, the upper case 56B is in the lowest position, and the middle case 62 is in the uppermost position. In this case, the accommodation space between the lower case 63 and the middle case 62 is maximized.
d1 is the distance in the vertical direction from the upper end of the first wall portion 63b to the lower surface of the middle case 62. The d1 may be 200 mm or more and 300 mm or less in order to easily take out and accommodate the 2L PET bottle 84 having a height of H1. More preferably, d1 is 267 mm ± 10 mm.
h1 is the height of the first wall portion 62b of the middle case 62. When the wall thickness is 3 mm, h1 may be 50 mm or more and 100 mm or less from the viewpoint of preventing the contained object from tipping over. h1 is more preferably 70 mm ± 10 mm. In this case, the height from the upper surface of the bottom surface portion 62a to the upper end of the first wall portion 62b (depth of the middle case 62) is 67 mm ± 10 mm.

The distances in the vertical direction from the upper end of the middle case 62 to the lower ends of the upper case 56B at the lowest position and the upper case 56A at the uppermost position are d2 and d3.
The d2 may be, for example, 50 mm or more and 100 mm or less so that the egg 85 can be easily taken out. It is more preferable that d2 is 54.8 mm or more.
When d2 has such a dimension, the height of the storage space from the upper case 56B to the rib 61F can be set to 146 mm or more and 257 mm or less, so that, for example, a milk carton 82 having a height H2 can be easily taken out and stored. ..
The d2 may have a size that allows the user's finger to enter even if the upper case 56B falls to the lowest position while the operation unit 59a is being gripped while the user is performing the unlocking operation. For example, if d2 is 50 mm or more, the user's finger can be inserted even if the upper case 56B is dropped during the unlocking operation. Even if the upper case 56B is dropped with the fingers inserted, there is no risk that the fingers will be pinched by the middle case 62 and the upper case 56B. Such d2 has a size that allows the user to perform an unlocking operation to push up the upper case 56B even when the upper case 56B is in the lowest position.
However, even when d2 is reduced, the height of the accommodation space from the upper case 56B to the rib 61F is more preferably set to less than H1 so that the 2L PET bottle 84 cannot be arranged.

The d3 may be, for example, 160 mm or more and 240 mm or less so that the dressing container 83 having a height H3 can be easily taken out. Since such d3 is less than H1, the size is such that the 2L PET bottle 84 cannot be arranged.

The dimension h2 from the lower end to the upper end in the upper cases 56A and 56B may be, for example, 45 mm or more and 130 mm or less. More preferably, h2 is 91.3 mm ± 10 mm. If h2 has such a dimension, the height from the lower surface of the bottom surface portion 57a of the case body 57 to the upper end of the case body 57 can be 70 mm ± 10 mm, and the contained object can be as in the middle case 62. It is possible to form a storage space that does not easily fall over.
When h2 has such a dimension, a 350 mL can 81 having a height of H4 can be arranged below the rib 61F in the upper case 56A. Therefore, even if the 350 mL cans 81 are densely housed in the upper case 56A, the user can easily take out the 350 mL cans 81.

FIG. 22 shows the positional relationship when the upper case 56A is in the uppermost position, the upper case 56B is in the lowest position, and the middle case 62 is in the lowest position. That is, from the state shown in FIG. 22, the middle case 62 is lowered by δ. In this case, the accommodation space between the lower case 63 and the middle case 62 is minimized.
The vertical distance from the upper end of the first wall portion 63b to the lower surface of the middle case 62 is reduced from d1 to D1 (= d1-δ). D1 may be 180 mm or more and 220 mm or less in order to easily take out and accommodate the milk carton 82 having a height of H2. D1 is more preferably 197.5 mm ± 10 mm.

The distance in the vertical direction from the upper end of the middle case 62 to the lower ends of the upper case 56B at the lowest position and the upper case 56A at the uppermost position increases from d2 and d3 to D2 (= d2 + δ) and D3 (= d3 + δ). do.
D2 may be, for example, 50 mm or more and 130 mm or less so that food can be easily taken out.
When D2 has such a dimension, the height of the storage space from the upper case 56B to the rib 61F can be 120 mm or more and 200 mm, so that, for example, eggs and dressings can be easily taken out and stored.
However, even when D2 is made smaller, the height of the accommodation space from the upper case 56B to the rib 61F is more preferably less than H1 so that the 2L PET bottle 84 cannot be arranged.
When D2 has such a size, the arrangement position of the middle case 62 is lowered, so that even a short user can easily take out the contents.

As described above, according to the refrigerator 1A of the present embodiment, in the rear surface member 53, the ribs 61A and 61B (61B, 61C) are provided with the rail portion 64 and the first stopper 53d, and are provided above the rail portion 64. Since the lower surface 61 g of the rib 61F, which is the second stopper, is provided, it is possible to prevent the upper case 56A (56B) from coming off or descending too much when the upper case 56A (56B) moves in the vertical direction.

(Second Embodiment)
The refrigerator of the second embodiment will be described.
FIG. 23 is a front view showing the refrigerator of the second embodiment.
The overall configuration of the refrigerator 1B of the second embodiment shown in FIG. 23 will be described focusing on the differences from the first embodiment. However, the refrigerator 1B does not have to have all of the configurations described below, and some configurations may be omitted as appropriate.

Refrigerator 1B has a housing 110 and a plurality of doors 111 in place of the housing 10 and the plurality of doors 11 of the refrigerator 1A.

The housing 110 includes an inner box, an outer box, and a heat insulating material similar to the housing 10. In the housing 110, various members forming the refrigerator main body 105 are arranged between the inner box and the outer box as in the case of the housing 10.

The housing 110 has a plurality of storage chambers 127 instead of the plurality of storage chambers 27 of the housing 10.
The plurality of storage chambers 127 include a refrigerator compartment 127A, a vegetable compartment 127B, an ice making chamber 127C, a small freezer compartment 127D, and a main freezer compartment 127E. The refrigerator compartment 127A and the vegetable compartment 127B are the same as the refrigerator compartment 27A and the vegetable compartment 27B.
The main freezing chamber 127E is located at the lowermost side of the housing 110. Between the vegetable compartment 127B and the main freezing chamber 127E, the ice making chamber 127C and the small freezing chamber 127D are arranged side by side in the + X direction.
The openings of the plurality of storage chambers 127 are opened and closed by the plurality of doors 111. The plurality of doors 111, for example, open the right refrigerating room door 111Aa (door), the left refrigerator door 111Ab (door), the vegetable room door 111B closing the opening of the vegetable room 127B, and the ice making room 127C. Includes an ice-making chamber door 111C, a small freezer door 111D that closes the opening of the small freezer 127D, and a main freezer door 111E that closes the opening of the main freezer 127E.
The right refrigerating room door 111Aa and the left refrigerator door 111Ab are double doors provided adjacent to each other on the left and right, and each has the same configuration as the refrigerating room door 11A of the first embodiment. In the present embodiment, the width of the right refrigerating chamber door 111Ab in the lateral width direction is larger than the width of the left refrigerating chamber door 111Aa in the lateral width direction.
The vegetable room door 111B, the ice making room door 111C, the small freezing room door 111D, and the main freezing room door 111E are pull-out doors similar to the vegetable room door 11B and the freezing room door 11C in the first embodiment.

Since the right refrigerating room door 111Aa and the left refrigerator door 111Ab have substantially the same configuration except for the size in the lateral width direction, the right refrigerating room door 111Aa will be described below.
FIG. 24 is a perspective view showing the refrigerator compartment door in the second embodiment.

As shown in FIG. 24, the right refrigerating chamber door 111Aa has substantially the same configuration as the refrigerating chamber door 11A except that the size is different. For example, the right refrigerating room door 111Aa has a well-known rotary partition plate attached to the end on the + Y direction side in the −X direction in order to open the double doors. In the following, in addition to the size, the points different from the refrigerator door 11A will be mainly described.
The right refrigerating chamber door 111Aa has an outer shell member 150 including a rear surface member 153 instead of the outer shell member 50 including the rear surface member 53. Further, the right refrigerating chamber door 111Aa replaces the upper case 56A, 56B, the middle case 62, and the lower case 63 with the upper case 156 (door container, upper door container), middle case 162 (door container, middle door container, etc.). It has a lower door container) and a lower case 163 (door container, lower door container).

The rear surface member 153 is the same as the rear surface member 53 except that the rib 61B is omitted. A gasket 55 similar to that of the first embodiment is attached to the outer peripheral portion of the rear surface member 153 on the + Y direction side.
The upper case 156 is locked to each of the rail portions 64 of the ribs 61A and 61C in the rear surface member 153 in the same manner as in the first embodiment. Therefore, the upper case 156 is configured in the same manner as the upper case 56A except that the width in the lateral width direction is matched with the widths of the ribs 61A and 61C in the rear surface member 153.
The middle case 162 is locked to the locking projections 66A and 66B (not shown) formed on the ribs 61A and 61C of the rear surface member 153 in the same manner as in the first embodiment. Therefore, the middle stage case 162 is configured in the same manner as the middle stage case 62 except that the width in the lateral width direction is matched with the widths of the ribs 61A and 61C in the rear surface member 153.
The lower case 163 is locked to the locking projections 65 (not shown) formed on the ribs 61A and 61C of the rear surface member 153 in the same manner as in the first embodiment. Therefore, the lower case 163 is configured in the same manner as the lower case 63 except that the width in the lateral width direction is matched with the widths of the ribs 61A and 61C.

According to the right refrigerating room door 111Aa, a single upper case 156 is provided above the middle case 162 so as to be movable in the vertical direction. The upper case 156 can be locked and unlocked with respect to the rail portion 64 by the same locking structure as in the first embodiment. Therefore, the upper case 156 can be moved in the vertical direction along the rail portion 64 by performing a push-up operation or an unlocking operation in the same manner as the upper case 56A of the first embodiment.
The right refrigerating room door 111Aa is an example in which the door container according to the first embodiment is provided on one of the double doors.

According to the refrigerator 1B of the present embodiment, the upper case 156 and the ribs 61A, 61C, 61F have the same locking projections 58A, the first stopper 53d, and the lower surface 61g as in the first embodiment. Similar to the embodiment, it is possible to prevent the upper case 156 from coming off or being lowered too much when the upper case 156 is moved in the vertical direction.

In the above embodiment, it has been described that the door container has a container body and an elevating table, and the container body is detachably attached to the elevating table, but the configuration of the door container is limited to this. Not done. For example, in the door container, the container body and the elevating table may be fixed so as not to be detachable. For example, the door container does not have to be divided into a container body and an elevating table by providing a first locking portion on a member having a function of the container body.
FIG. 25 is a perspective view showing a modified example of the door container that can be used for the refrigerator of each embodiment.

The upper case 256 (door container, upper door container) shown in FIG. 25 is used in place of the upper cases 56A, 56B, and 156 of the refrigerators 1A and 1B of each of the above embodiments by appropriately setting the width in the width direction. Can be done. Hereinafter, the upper case 256 of this modification will be described focusing on the differences from the upper case 56A in the first embodiment.

The upper case 256 has a case main body 258 (container main body) instead of the elevating base main body 58 by deleting the case main body 57 of the upper case 56A.
The case body 258 has a first wall portion 57b, a first side wall portion 57f, and a second side wall portion 58f in place of the first wall portion 58b, the first side wall portion 58f, the second side wall portion 58d, and the step portion 58e of the lift main body 58. It has a side wall portion 258d and a step portion 258e.
The first wall portion 57b and the first side wall portion 57f in this modification are different from the first embodiment in that they are provided at the edge of the wide portion on the bottom surface portion 58a.
The second side wall portion 258d has the same locking projections 58A and guide plate 58B as in the first embodiment, and the point that the concave groove 58j in the second side wall portion 58d is deleted is the second point. It is different from the side wall portion 58d.
Flange portions 57g and 57j similar to those in the first embodiment are formed at the upper ends of the second side wall portion 258d and the second wall portion 58c of this modification. The flange portion 57j is not provided with the ridge 57i.
The length L258 from the upper end of the flange portion 57j to the lower end 58Ac of the locking projection 58A is shorter than the gap distance of the gap G1.
The flange portions 57g and 57j in this modification do not have a function of locking to the upper end of the elevator body 58. Therefore, if the strength required for the upper case 256 is obtained, the flange portions 57g and 57j may be omitted.
The step portion 258e is connected to the end portion of the first side wall portion 57f in the −Y direction and the end portion of the second side wall portion 258d in the + Y direction in the lateral width direction. Each step portion 258e faces the tip of the ribs 61A and 61B in the protruding direction when the upper case 256 is mounted on the refrigerator compartment door 11A.

A lower cover 60 similar to that of the first embodiment is fixed to the lower surface side of the case main body 258, and a bottom plate portion similar to that of the elevating base main body 58 is formed. The bottom plate portion is provided with a first locking portion 70 as in the first embodiment.
Similar to the first embodiment, the first locking portion 70 can be moved to a locking position and a non-locking position by an operating member 59 and an urging member 77 (not shown).

According to this modification, the upper case 256 can be pulled out from the gap G1 in the + Y direction. In the upper case 256, since the first locking portion 70 is provided on the bottom plate portion of the case body 258, only the case body 258 cannot be removed from the upper case 256, but the upper case 256 is the upper case 56A. Similarly, the rail portion 64 can be locked so as to be movable in the vertical direction.
Therefore, in the refrigerator having the upper case 256 of this modified example, the arrangement position of the upper case 256 in the vertical direction can be easily changed as in the first embodiment.

In the above embodiment, it has been described that the concave-convex structure in the rail portion 64 has a plurality of locking surfaces extending in the horizontal direction and a plurality of inclined surfaces inclined with respect to the horizontal plane, but the shape of the concave-convex structure is not limited to this. ..
FIG. 26 is a perspective view showing a modified example of the second locking portion that can be used in the refrigerator of each embodiment.

The rail portion 64A shown in FIG. 26A has a first rail portion 64Aa instead of the first rail portion 64a of the rail portion 64. The first rail portion 64Aa has a plurality of locking plates 64Ae instead of the plurality of locking plates 64a.
The locking plate 64Ae has a plurality of locking surfaces according to the first embodiment in that the upper locking surface 64Ai is inclined downward in the protruding direction of the locking plate 64Ae due to a change in the plate thickness in the protruding direction. It is different from the plate 64e. The inclination angle of the locking surface 64Ai with respect to the horizontal plane is ψ, which is smaller than the inclination angle φ of the inclination rib 64f.

According to this modification, since the locking surface 64Ai is inclined, when the locking member 73 is raised, after passing through the tips of the plurality of locking plates 64Ae, the tip of the locking member 73 is the locking surface 64Ai. Sliding with and gradually advancing toward the side surface. At this time, the locking member 73 makes extensive contact with the inclined rib 64f on the inclined surface 73b, whereas the locking surface 64Ai engages with the locking surface 64Ai linearly or in a dot shape at the lower end of the tip of the main body 73a. It comes into contact with the retaining surface 64Ai. Therefore, coupled with the fact that the inclination angle ψ is smaller than φ, the locking member 73 smoothly advances while sliding on the locking surface 64Ai. Therefore, it is possible to suppress the generation of an impact sound when the locking member 73 advances.
When the locking member 73 is locked with the locking surface 64Ai, the load of the upper case 56A is concentrated on the locking portion and the pressure is increased, so that the locking member 73 is less likely to slip downward.
This modification is an example in which the locking surface may be inclined from the horizontal plane.

The rail portion 64B shown in FIG. 26B has a first rail portion 64Ba instead of the first rail portion 64a of the rail portion 64. The first rail portion 64ba has a plurality of flat plates 64Be instead of the plurality of locking plates 64e, and a plurality of inclined ribs 64Bf are added.
The plurality of flat plates 64e are the same as the plurality of locking plates 64e except that they do not have a locking surface for locking the locking member 73.
The plurality of inclined ribs 64Bf have a triangular shape provided between the upper surface of each of the plurality of flat plates 64e and the side surfaces S (Sm, Sp). The plurality of inclined ribs 64Bf are arranged in the same number as the plurality of inclined ribs 64f in the depth direction. Each inclination angle of the plurality of inclined ribs 64Bf with respect to the horizontal plane is φ with respect to the upper surface of the flat plate 64Be. Therefore, the inclined ribs 64f and 64Bf sandwiching the flat plate 64Be have a shape and arrangement that are plane-symmetrical with respect to the center of the flat plate 64Be in the vertical direction.
The upper end surfaces of the plurality of inclined ribs 64Bf form a locking surface to which the locking member 73 is locked.

According to this modification, since the inclined ribs 64Bf and 64f are plane-symmetrical in the vertical direction, the magnitude of the inclination of the concave-convex structure is the same in the vertical direction. Therefore, as compared with the first rail portion 64Aa, it is possible to further suppress the generation of impact noise when the locking member 73 advances.
Since the inclined surface 73b is formed only on the upper surface at the tip of the locking member 73, the resistance at the time of descending becomes larger than that at the time of ascending. Therefore, the locking member 73 can be locked on the inclined rib 64Bf by setting the inclination angle to φ as appropriate.
This modification is an example in which the concave-convex shape of the concave-convex structure may have a plane-symmetrical shape in the vertical direction.
Further, in this modification, the locking surface for locking the locking member is formed by the tip end portion of the inclined rib 64Bf.

In the above embodiment, the first locking portion is provided on the door container, and the second locking portion is provided on the inner surface portion of the door. In this case, the door container and the inner surface of the door are examples of the first member and the second member, respectively. However, the first member and the second member may be interchanged. That is, the first locking portion may be provided on the inner surface portion of the door, and the second locking portion may be provided on the door container.

In the above embodiment, the shapes and arrangements of the door container, the first locking portion, the second locking portion, the first stopper, and the unlocking mechanism are symmetrical, but the door container, the first locking The shapes and arrangements of the portion, the second locking portion, the first stopper, and the unlocking mechanism do not have to be symmetrical.

In the above embodiment, the case where the first locking portion, the second locking portion, and the first stopper are provided at two locations sandwiching the door container in the lateral width direction has been described. However, if at least one first locking portion and one second locking portion can support the door container and its contents, the first locking portion, the second locking portion, and the first stopper may be 1 It may be provided at a location.

In the above embodiment, the example in which the locking surface in the second locking portion is provided at a pitch Δ that divides the moving range into five equal parts has been described, but by increasing the number of locking surfaces and the number of uneven portions. , Pitch Δ can be made as small as possible.

In the above embodiment, it has been described that the door container has a locking protrusion, and the first stopper locks the locking protrusion to regulate the lowering position of the door container. However, the first stopper may be locked with the door container other than the locking projection as long as the lowering position of the door container can be regulated. For example, the first stopper may be locked with an uneven shape formed on a surface other than the locking projection of the door container. For example, the first stopper may be locked to the lower surface of the door container.

In the above embodiment, it has been described that the first stopper is provided between the rail portion and the step portion. In this case, since the locking projection is a moving path between the rail portion and the step portion, the lowering position of the door container can be regulated by blocking the movement of the locking projection. For example, when the first stopper is connected to the rail portion and the step portion as in the first stopper 53d, there is an advantage that the strength of the first stopper is improved by the rail portion and the step portion.
However, the first stopper may be provided in a range where the door container is lowered between the rail portion and the inner surface portion. For example, the first stopper may be provided on the flat portion 53a.

In the above embodiment, it has been described that each locking projection is composed of one projection that is long in the vertical direction. However, each locking projection may be a plurality of projections that are separated in the vertical direction and project in the lateral width direction. Further, the shape of the locking projection is not limited to a shape that is long in the vertical direction. For example, the shape of the locking projection may have a round bar-shaped or square bar-shaped outer shape in which the lengths in the vertical direction and the depth direction are substantially the same.

In the above embodiment, the middle case 62 located between the upper cases 56A and 56B and the lower case 63 can be moved in two stages between the first position and the second position. The case 62 may be movable in three or more stages.
Further, the middle case 62 may have a first locking portion and a locking release mechanism similar to the upper case 56A so that the middle case 62 can be moved in multiple stages like the upper case 56A.

In the above embodiment, the upper door containers 56A and 56B are arranged in the horizontal width direction as the upper door container, but the number of the upper door containers is not limited to two. For example, three or more upper door containers may be provided in the width direction. For example, two or more upper door containers may be provided so as to overlap in the vertical direction.

In the above embodiment, the upper limit value and the lower limit value of the moving range of the plurality of upper door containers are equal to each other, but at least one of the upper limit value and the lower limit value of the moving range of the plurality of upper door containers is different from each other. You may be. The upper limit of the moving range of the upper door container is determined by the vertical length of the second locking portion. The lower limit of the moving range of the upper door container is determined by the position of the lowest locking surface or the position of the first stopper.
From the viewpoint of facilitating the placement of high inclusions in a portion where the centrifugal force acting when opening and closing the refrigerating chamber door 11A is small, for example, the lower limit of the moving range in the upper door container is the most on the hinge of the door. It is more preferable that the lower limit value of the near upper door container is the highest. In this case, a high container can be placed in the middle door container below the upper door container closest to the hinge.
Similarly, for example, as for the upper limit value of the movement range in the upper door container, it is more preferable that the upper limit value of the upper door container closest to the hinge of the door is the highest. In this case, a high container can be placed in the middle door container below the upper door container closest to the hinge.

According to at least one embodiment described above, the refrigerator includes a door, a first wall body portion, a second wall body portion, a rail portion, a door container, a first stopper, and a second stopper. have. The door container can move vertically between the first wall body and the second wall along the rail portion, and is locked from above with at least one of the first wall body and the second wall body. It is possible. The first stopper is arranged between the rail portion and the inner surface portion when viewed from above, and regulates the lowering position of the door container. The second stopper is provided on at least one of the inner surface portion, the first wall body portion, and the second wall body portion above the upper end of the rail portion, and regulates the ascending position of the door container to control the door container. Prevents the rail from coming off from the upper side. Therefore, it is possible to provide a refrigerator capable of preventing the door container from coming off or being lowered too much when the door container is moved in the vertical direction.
