Description

Embodiments of the present invention relate to a refrigerator.

It is known to provide a door container on the door of a storage compartment in a refrigerator, which is movable in the vertical direction and is detachable from the door. For example, the bottom portion of the door container is provided with a locking mechanism that locks with the door and an operating member that operates the locking mechanism.
However, in the case of a refrigerator having a revolving door, it is necessary to round the corner of the door container on the opposite side of the hinge according to the rotation radius of the revolving door. As a result, the area of the bottom portion on which the operating member is provided becomes narrower, which places restrictions on the size of the operating member. If the operating member is small, the locking mechanism may not be easily operated.

[First embodiment]
A refrigerator according to a first embodiment will be explained.
FIG. 1 is a front view showing the refrigerator of the first embodiment with the door opened. The overall configuration of a refrigerator 1A according to the first embodiment shown in FIG. 1 will be described. However, the refrigerator 1A does not need to have all of the configurations described below, and some configurations may be omitted as appropriate.

The refrigerator 1A includes, for example, a housing 10, a pair of refrigerator doors 12 and 13 (doors, rotating doors), and a plurality of doors 11.
The housing 10 includes, for example, an inner box, an outer box, and a heat insulator.
The inner box is made of synthetic resin, for example, and has a concave shape at multiple locations from the front side toward the rear side. Each recess in the inner box forms a plurality of storage chambers 27. In the example shown in FIG. 1, the plurality of storage compartments 27 include a refrigerator compartment 27A, a vegetable compartment 27B, an upper freezing compartment 27C, a lower freezing compartment 27D, and an ice making compartment 27E. The refrigerator compartment 27A, the vegetable compartment 27B, the upper freezer compartment 27C, and the lower freezer compartment 27D are arranged in this order from the top to the bottom. The ice making compartment 27E is located on the left side of the upper freezing compartment 27C.
The housing 10 has an opening on the front side of each storage chamber 27 that allows food to be taken in and out of each storage chamber 27.
The outer box is in the shape of a rectangular parallelepiped and forms the outer surface portions of the housing 10 on three sides excluding the front side. The outer box is made of, for example, metal or a composite material of metal and resin.
The heat insulating material is a foamed heat insulating material such as urethane foam, and is filled between the inner box and the outer box. Thereby, the housing 10 has heat insulation properties.

In the housing 10, various members that together with the housing 10 form the refrigerator body 5 are arranged between the inner box and the outer box. The members forming the refrigerator body 5 include, for example, a cooling unit that forms cold air, a flow path forming member that forms a flow path that circulates cold air between each storage chamber 27 and the cooling unit, and a flow path forming member that circulates cold air between each storage chamber 27 and the cooling unit. Examples include a cooling fan that feeds the storage room 27 and a control board that controls the operation of the cooling unit and the cooling fan.

The indoor temperature of the refrigerator compartment 27A is maintained lower than the vegetable compartment 27B and higher than the upper freezer compartment 27C and the lower freezer compartment 27D. Inside the refrigerator compartment 27A, for example, a shelf that partitions the room, a chilled room container, and the like are arranged. The front surface of the refrigerator compartment 27A is covered by refrigerator compartment doors 12 and 13 that open left and right so that they can be opened and closed.

The refrigerator compartment doors 12 and 13, as shown in FIG. 1, are doors provided to open and close the refrigerator compartment 27A. The refrigerator compartment door 12 covers the left side of the opening of the refrigerator compartment 27A when closed. The refrigerator compartment door 13 covers the right side of the opening of the refrigerator compartment 27A when closed. The end of the refrigerator compartment door 12 in the +X direction and the end of the refrigerator compartment door 13 in the −X direction face each other with a slight gap in the width direction when closed. The gap between the refrigerator compartment doors 12 and 13 in the width direction when closed is closed by, for example, a rotary partition plate 68 provided on the refrigerator compartment door 12.
The width dimensions of the refrigerator compartment doors 12 and 13 in the lateral direction may be equal to each other or may be different from each other. In the example shown in FIG. 1, the width dimensions are different from each other, and the width dimension of the refrigerator compartment door 12 is smaller than the width dimension of the refrigerator compartment door 13.

The refrigerator compartment door 12 is connected to the end of the housing 10 in the -X direction, for example, by a pair of hinges 32 provided at the upper and lower ends in the -X direction, respectively. The refrigerator compartment door 12 is rotatable in a horizontal plane about a rotation axis _OL of a hinge 32 that extends in the vertical direction.
The refrigerator door 13 is connected to the end of the housing 10 in the +X direction, for example, by a pair of hinges 33 provided at the upper and lower ends in the +X direction. The refrigerator compartment door 13 is rotatable in a horizontal plane about a rotation axis _OR of a hinge 33 that extends in the vertical direction.
In this way, the refrigerator compartment doors 12 and 13 are double-opening revolving doors (left-right double-opening revolving doors) that rotate and open toward the left and right sides, respectively. The user can open the refrigerator compartment doors 12, 13 from side to side while rotating them by placing a hand on each groove 8 provided at the lower end of each refrigerator compartment door 12, 13 and pulling forward.
In the example shown in FIG. 1, the radius of rotation r _L of the end of the refrigerator compartment door 12 in the +X direction is smaller than the radius of rotation r _R of the end of the refrigerator compartment door 13 in the −X direction.
A revolving door that opens both left and right is sometimes called a double door or a French door, for example.

The plurality of doors 11 are doors provided to open and close the vegetable compartment 27B, the upper freezer compartment 27C, the lower freezer compartment 27D, and the ice making compartment 27E. The vegetable compartment door 11B, the upper freezer compartment door 11C, the lower freezer compartment door 11D, and the ice making compartment door 11E cover the respective front surfaces of the vegetable compartment 27B, the upper freezing compartment 27C, the lower freezing compartment 27D, and the ice making compartment 27E.

The indoor temperature of the vegetable compartment 27B is maintained at a higher temperature than that of the refrigerator compartment 27A. Inside the vegetable compartment 27B, there are provided, for example, a vegetable compartment container for storing stored items such as vegetables, and a guide rail for moving the vegetable compartment container in the depth direction.
The front surface of the vegetable compartment 27B is covered by a pull-out vegetable compartment door 11B so that it can be opened and closed.

The indoor temperatures of the upper freezing compartment 27C, lower freezing compartment 27D, and ice making compartment 27E are each maintained at a temperature at which stored items can be frozen. Inside the upper freezing compartment 27C, lower freezing compartment 27D, and ice making compartment 27E, for example, a small freezing compartment, a freezing compartment container for storing stored items to be frozen, and a guide rail for moving the freezing compartment container in the depth direction are provided. , etc. are provided.
The front surfaces of the upper freezer compartment 27C, lower freezer compartment 27D, and ice making compartment 27E are covered in an openable/closable manner by a pull-out upper freezer compartment door 11C, a lower freezing compartment door 11D, and an ice making compartment door 11E.

The configurations of each storage room 27 and each door 11 described above are merely examples, and are not limited to the above examples. For example, the doors 11 of the storage compartments 27 other than the refrigerator compartment 27A may be revolving doors or may be double-opening revolving doors.

As shown in FIG. 1 when the refrigerator compartment doors 12 and 13 are opened, a plurality of door containers are arranged inside each of the refrigerator compartment doors 12 and 13.
For example, inside the refrigerator compartment door 12, door containers 56B, 56A, and a lower door container 56C are arranged in this order in the −Z direction. For example, inside the refrigerator compartment door 13, door containers 54B, 54A, and a lower door container 54C are arranged in this order in the -Z direction. However, the number of door containers in each of the refrigerator compartment doors 12 and 13 in this embodiment is not limited to this. For example, one door container may be arranged in each of the refrigerator compartment doors 12 and 13, or four or more door containers may be arranged in each of the refrigerator compartment doors 12 and 13.

The door containers 56A and 56B disposed above the lower door container 56C are movable in the vertical direction with respect to an inner surface forming the inner surface in the +Y direction of the refrigerator compartment door 12, and are detachably attached. The vertical positions of the door containers 56A and 56B can be fixed at a plurality of locations within the vertical movement range.
Here, the vertical movement pitch and movement range of the door containers 56A, 56B are not particularly limited.
The lower door container 56C may be removably attached to the inner surface of the refrigerator compartment door 12, or may be fixed to the inner surface.

The door containers 54A and 54B arranged above the lower door container 54C are movable in the vertical direction with respect to an inner surface forming the inner surface in the +Y direction of the refrigerator compartment door 13, and are detachably attached. The vertical positions of the door containers 54A and 54B can be fixed at multiple locations within the vertical movement range.
Here, the vertical movement pitch and movement range of the door containers 54A, 54B are not particularly limited.
The lower door container 54C may be removably attached to the inner surface of the refrigerator compartment door 13, or may be fixed to the inner surface.

Next, the detailed configuration of the refrigerator compartment doors 12 and 13 will be explained. However, since the refrigerator compartment doors 12 and 13 have the same basic structure except that the arrangement position and the width dimension are different, the following description will focus on the example of the refrigerator compartment door 12.
FIG. 2 is a perspective view showing the refrigerator compartment door 12 in the first embodiment.
As shown in FIG. 2, the refrigerator compartment door 12 includes, for example, an outer shell member 50A, a gasket 55A, and a rotating partition plate 68.

The outer shell member 50A is formed into a box shape. The term "box-like" as used herein includes a flat box-like shape. The outer member 50A includes, for example, a frame 51A, a front plate 52A, and a rear member 53A (inner surface portion).

The frame body 51A is a rectangular frame when viewed from the -Y direction. The frame 51A includes an upper side member 51a, a lower side member 51b, and side members 51c and 51d. In the state where the refrigerator compartment door 12 is closed, the upper side member 51a has a plate shape extending in the width direction and the depth direction, and forms the upper surface of the refrigerator compartment door 12. The lower side member 51b has a plate shape extending in the width direction and the depth direction, and forms the lower surface of the refrigerator compartment door 12. The side members 51c and 51d are plate-shaped along the vertical direction and the depth direction. The side member 51c forms a side surface in the +X direction. The side member 51d forms a side surface in the -X direction.
The frame 51A is made of, for example, synthetic resin.
A groove portion 8 recessed in the +Z direction is formed in the lower side member 51b. The groove portion 8 is formed at the end of the lower side member 51b in the +X direction. The user can place his hand in the groove 8 when opening the refrigerator compartment door 12.

The front plate 52A is attached to close the opening in the -Y direction of the frame 51A, and is located at the front end of the refrigerator compartment door 12. The front plate 52A is a rectangular plate member that extends along the frame 51A, and forms the front surface of the refrigerator compartment door 12. The front plate 52A is, for example, a glass plate. However, the front plate 52A is not limited to a glass plate, and may be made of synthetic resin or other materials. The front plate 52A may be a flat plate or a curved plate. In the following, an example in which the front plate 52A is a flat plate will be described.

The rear member 53A is attached to the frame 51A from the opposite side to the front plate 52A, and is located at the rear end of the refrigerator compartment door 12. The outer shape of the rear member 53A when viewed from the -Y direction is a rectangle along the frame 51A. The rear member 53A is made of synthetic resin, for example.
The rear member 53A has a planar inner surface 53a facing in the +Y direction, and a rib 61 protruding in the +Y direction from the outer peripheral edge of the inner surface 53a.

The rib 61 protrudes beyond the frame 51A and the inner surface 53a in the +Y direction toward the refrigerator compartment 27A when the refrigerator compartment door 12 closes the opening of the refrigerator compartment 27A (when closed). A foamed heat insulating material is filled between the rear member 53A and the front plate 52A and the inside of the convex shape of the rib 61.
The ribs 61 are provided mainly to prevent cold air in the refrigerator compartment 27A from escaping through the gap between the refrigerator compartment door 12 and the housing 10.
Note that in this specification, the term "rib" is a name for convenience of explanation, broadly refers to a portion that protrudes rearward from the rear surface member 53A, and is not limited to a specific shape or function.

The gasket 55A is provided to seal the refrigerator compartment 27A so that the cold air in the refrigerator compartment 27A does not leak to the outside from between the refrigerator compartment door 12 and the housing 10 when the refrigerator compartment door 12 is closed. .
The gasket 55A has an annular shape surrounding the outer periphery of the frame 51A and is attached to the rear member 53A. The method of attaching the gasket 55A is not particularly limited. For example, the gasket 55A may be attached by fitting a protrusion for attachment provided on the gasket 55A and a concave portion for attachment provided on the rear member 53A.

The rotary partition plate 68 extends vertically along the gasket 55A in the +Y direction of the gasket 55A adjacent to the side member 51c of the refrigerator compartment door 12. The upper and lower ends of the rotary partition plate 68 are connected to the rear member 53A so as to be rotatable in a horizontal plane via a rotary support member (not shown).
The rotating partition plate 68 rotates toward the rib 61 near the side member 51c when the refrigerator compartment door 12 is opened as shown in FIG. It is located in the X direction.
When the refrigerator compartment door 12 is closed, the rotary partition plate 68 rotates clockwise when viewed from the -Z direction and protrudes beyond the side member 51c in the +X direction. Thereby, a flat plate portion is formed in which the gasket 55A and a gasket 55B of the refrigerator compartment door 13, which will be described later, can be brought into close contact with each other.

Here, the detailed configuration of the rear surface member 53A will be explained.
FIG. 3 is a perspective view showing the rear member 53A of the refrigerator compartment door 12.
As shown in FIG. 3, the ribs 61 include a rib 61F extending in the width direction along the upper side member 51a, a rib 61G extending in the width direction along the lower side member 51b, and a rib 61G extending in the vertical direction along the side member 51c. It has a rib 61C that extends vertically along the side member 51d, and a rib 61D that extends in the vertical direction along the side member 51d. The lengths of the ribs 61F and 61G in the width direction are equal to each other. The lengths of the ribs 61C and 61D in the vertical direction are equal to each other.

The ribs 61C, 61D, and 61G protrude further in the +Y direction than the rib 61F. The amount of protrusion of the rib 61F is large enough to prevent the door containers 56A, 56B from coming off when the door containers 56A, 56B move in the +Z direction.

The rib 61C has a side surface S1 facing in the -X direction. The rib 61D has a side surface S2 facing in the +X direction. Each side surface S1, S2 is a plane substantially perpendicular to the inner surface 53a. The side surfaces S1 and S2 face each other in the width direction.

A step portion 53c, a rail portion 64, and a locking protrusion 65 are provided on the side surface S1 of the rib 61C, respectively.
The step portion 53c protrudes from the side surface S1 in the −X direction, and extends in the −Z direction from the lower surface 61g (see FIG. 2) of the rib 61F.

The rail portion 64 guides the door containers 56A, 56B in the vertical direction while regulating the position in the depth direction when moving the door containers 56A, 56B, which will be described later, in the vertical direction.
The rail portion 64 protrudes from the side surface S1 in the −X direction, and extends vertically parallel to the end surface 53cy with a gap between the rail portion 64 and the end surface 53cy of the step portion 53c in the +Y direction.
The protrusion height of the rail portion 64 from the side surface S1 may be different from or the same as the protrusion height of the step portion 53c. For example, the protruding height of the rail portion 64 may be lower than the protruding height of the end surface 53cx, which is the end surface in the −X direction of the step portion 53c. In this case, the end surface 53cx of the stepped portion 53c approaches the side surface in the +X direction of the door containers 56A, 56B, which will be described later, and can function as a guide surface in the width direction of the door containers 56A, 56B.

A groove g1 extending in the vertical direction is formed between the rail portion 64 and the end surface 53cy.
The concave groove g1 has a constant groove width except that the width is narrowed by the convex portion p bulging from the step portion 53c near the upper end of the rail portion 64. The protrusion p may be deleted if a space for arranging components can be secured inside the rib 61C.

The upper end of the rail portion 64 is formed at a lower position than the upper end of the rib 61C. Therefore, when viewed from the −Y direction, a gap G1 is formed between the upper end of the rail portion 64 and the rib 61F.
The lower end of the rail portion 64 and the lower end of the step portion 53c are formed at the same position in the vertical direction. A lowering position regulating portion 53d that protrudes inside the groove g1 is provided between the lower end of the rail portion 64 and the lower end of the step portion 53c. The descending position regulating portion 53d is provided to regulate the descending position of the door container 56B.
The shape of the descending position regulating portion 53d is not particularly limited as long as it can regulate the descending position of the door container 56B. In the example shown in FIG. 3, the lowering position regulating portion 53d is a plate that connects the lower end of the rail portion 64 and the end surface 53cy of the step portion 53c, and closes the groove g1 from below.
The vertical position of the lowering position regulating portion 53d is an appropriate position depending on the lowermost position of the door container 56B.
A reinforcing rib 64fb is provided between the lower surface of the descending position regulating portion 53d and the side surface S1 for reinforcing the descending position regulating portion 53d against external forces acting from above.

The rail portion 64 has a first rail portion 64a and a second rail portion 64b in this order in the +Z direction.
The first rail portion 64a guides the vertical movement of the door containers 56A, 56B, which will be described later, and also regulates the vertical movement positions of the door containers 56A, 56B in multiple stages.
The first rail portion 64a includes a first guide 64c, a second guide 64d, a plurality of locking plates 64e, an upper end plate 64g, a lower end plate 64k, and a plurality of inclined ribs 64fa.

The first guide 64c forms a side surface of the rail portion 64 in the -Y direction. The first guide 64c is a flat plate that protrudes from the side surface S1 in the -X direction and extends in the vertical direction. The first guide 64c extends to the second rail portion 64b.
The second guide 64d forms a side surface of the rail portion 64 in the +Y direction. The second guide 64d is a flat plate that protrudes from the side surface S1 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, like the first guide 64c, extends to the second rail portion 64b.
The ends of the first guide 64c and the second guide 64d in the −X direction are located on the same plane orthogonal to the depth direction.

The plurality of locking plates 64e extend in the depth direction between the first guide 64c and the second guide 64d, and protrude from the side surface S1 in the −X direction. The plurality of locking plates 64e are provided vertically apart from each other 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. 3. The size of the pitch 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. 3, seventeen locking plates 64e are arranged.
The tip of each locking plate 64e in the protruding direction is located on the same plane as the tips of the first guide 64c and second guide 64d located on both sides of each locking plate 64e in the width direction.

The upper end plate 64g is a plate that extends in the depth direction between the first guide 64c and the second guide 64d and projects perpendicularly from the side surface S1. The upper end plate 64g is located above the plurality of locking plates 64e, and is spaced upward from the uppermost locking plate 64e at a pitch substantially equal to the pitch between the locking plates 64e.

The lower end plate 64k is a plate that extends in the depth direction between the first guide 64c and the second guide 64d and projects perpendicularly from the side surface S1. The lower end plate 64k is located below the lowest locking plate 64e, and is spaced downward from the lowest locking plate 64e at an interval wider than the pitch between the locking plates 64e.

The plurality of inclined ribs 64fa are provided on the lower surface side of each locking plate 64e except for the lower end plate 64k, and on the lower surface side of the upper end plate 64g. A pair of inclined ribs 64fa are provided on the lower surface of each locking plate 64e and on the lower surface of the upper end plate 64g, and are spaced apart from each other in the depth direction. Furthermore, each of the inclined ribs 64fa is also arranged at intervals in the depth direction with respect to the first guide 64c and the second guide 64d.
The shape of each inclined rib 64fa when viewed from the −Y direction is a triangle that slopes toward the side surface S1 as it advances in the −Z direction from each tip in the −X direction of each locking plate 64e and upper end plate 64g.

With this configuration, inside the first rail portion 64a, a plurality of convex portions are vertically lined up at substantially equal intervals from the bottom to the top. The plurality of convex portions include an inclined portion 64j formed at the tip of the inclined rib 64fa in the −X direction, a distal end surface of the locking plate 64e, and a locking surface extending in the horizontal direction formed by the upper surface of the locking plate 64e. 64i. Relative recesses are formed between the respective projections protruding from the side surface S1 in the X direction. Therefore, a sawtooth-like uneven structure is formed inside the first rail portion 64a, with the inclined portion 64j facing downward.
A locking portion 70, which will be described later, locks onto each locking surface 64i in the uneven structure of the rail portion 64 from above.
The inclined portion 64j at the lower end of the plurality of inclined ribs 64fa is inclined so as to be able to press the locking portion 70 toward the door container 56A as the locking portion 70, which will be described later, moves upward from the locking surface 64i.

The second rail portion 64b includes upper end portions of the first guide 64c and the second guide 64d in the first rail portion 64a, and an intermediate rib 64h extending in the vertical direction between the upper end portions. The intermediate rib 64h is a flat plate parallel to the first guide 64c and the second guide 64d. The length of the intermediate rib 64h in the vertical direction is equal to the length from the upper end plate 64g to the upper ends 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 protrusion height of the intermediate rib 64h in the -X direction is equal to the protrusion height of the first guide 64c and the second guide 64d.

The size of the locking protrusion 58DL in the width direction and the depth direction is such that it can be accommodated inside the groove g1.
The distance h2 from the lower end of the locking protrusion 58DL to the upper surface of the flat plate portion 58EL is smaller than the size of the gap G1 in the vertical direction. The lifting platform main body 58 can pass through the gap G1 in the rib 61D.

A groove 58j for positioning a container body 57, which will be described later, in the depth direction is formed at the upper end of the first side wall portion 58dL. The shape of the groove 58j when viewed from the +X direction is, for example, a U-shape that opens in the +Z direction.
Although the position of the groove 58j viewed from the +X direction is not particularly limited, in the example shown in FIG. 8, it is between the first rear wall portion 58eL and the guide protrusion 58CL.

FIG. 9 is a side view of FIG. 6 viewed from F9.
As shown in FIG. 9, the second side wall portions 58dR, 58dRb are similar to the first side wall portions 58dL, 58dLb, except that they are formed in a plane-symmetrical position and shape with respect to a plane of symmetry parallel to the YZ plane. It has a stop protrusion 58F, a groove 58j, and a guide hole 58u.
The second side wall portions 58dR, 58dRb have a guide projection 58CR, a flat plate portion 58ER, and a locking projection 58DR in place of the guide projection 58CL, flat plate portion 58EL, and locking projection 58DL in the first side wall portions 58dL, 58dLb.

The lower cover 60 includes a bottom plate portion 60a and side plate portions 60bL, 60bR, and 60c extending in the +Z direction from the outer edge of the bottom plate portion 60a.

The bottom plate portion 60a is a flat plate having approximately the same external shape as the upper surface portion 58a of the lifting platform main body 58. However, a notch 60e having a rectangular shape in plan view is formed at the end of the bottom plate 60a in the +Y direction.
A screw hole portion 60d through which a screw 76 is inserted passes through the bottom plate portion 60a at a position facing each screw fixing portion 58r (see FIG. 7) in the elevator main body 58 in plan view.

The side plate parts 60bL and 60bR are walls projecting in the +Z direction from slightly inside the outer peripheral edge of the bottom plate part 60a, and are respectively provided at both ends of the bottom plate part 60a in the width direction with the notch part 60e in between. . The protrusion height of the side plate parts 60bL and 60bR from the bottom plate part 60a is less than or equal to the protrusion height of the third rear wall part 58b and the like from the upper surface part 58a.
FIG. 10 is a sectional view taken along line F12-F12 in FIG. 4.
As shown in FIG. 10, the side plate portion 60bL extends from the end of the cutout portion 60e in the −X direction to the guide portion 58t in the −X direction, and includes the third rear wall portion 58b of the lifting platform main body 58, the third It is formed along the inside of the side wall portion 58f, the fourth wall portion 58eLb, and the first side wall portion 58dLb.

The side plate portion 60c is a wall that protrudes in the +Z direction from slightly inside the outer peripheral edge of the bottom plate portion 60a in the −Y direction than each guide portion 58t. The side plate portion 60c is formed along the inside of the first side wall portion 58dLb, the front wall portion 58cb, and the second side wall portion 58dRb of the elevator main body 58. The protruding height of the side plate portion 60c is equal to the protruding height of the side plate portions 60bL and 60bR.

The lower cover 60 is fitted from below inside the lower part of the lifting table main body 58 and is fixed to the lifting table main body 58 by a plurality of screws 76 .

Next, the operating member 59 will be explained.
As shown in FIG. 6, the operating member 59 is held between the housing portion 58A and the lower cover 60 so as to be movable in the depth direction.
11 and 12 are perspective views showing the operating member in the first embodiment. FIG. 13 is a sectional view taken along line F13-F13 in FIG. 10.

As shown in FIG. 11, the operating member 59 includes an operating section 59A and an operating section 59X. The operating portion 59A has a rectangular shape in plan view that is long in the width direction. An operation plate 59a along the ZX plane is provided at the end of the operation section 59A in the +Y direction. A connecting plate 59c parallel to the operating plate 59a is provided at the end of the operating section 59A in the -Y direction.
Each end of the operating plate 59a and the connecting plate 59c in the −X direction is connected to each other by a side plate portion 59bL extending in the depth direction along the YZ plane. Similarly, the ends in the +X direction are connected to each other by side plate portions 59bR extending in the depth direction along the YZ plane.

A groove V opening in the −Z direction is formed between the operation plate 59a and the connecting plate 59c between the side plate portions 59bL and 59bR. The groove width of the groove V in the depth direction is large enough to allow insertion of a user's fingertip. The groove width of the groove V in the width direction is large enough to allow the user's second to fifth fingers to be inserted with a gap between them. Hereinafter, for simplicity, at least one of the second to fifth fingers may be referred to as a non-first finger.
The groove V may be formed entirely between the operation plate 59a and the connection plate 59c, but in the example shown in FIG. It is formed up to the middle part between. The inner circumferential surface of the concave groove V in the -Y direction is formed by a flat plate part 59f parallel to the operation plate 59a, and the end part of the flat plate part 59f in the -Z direction and the end part of the connecting plate 59c in the -Z direction. are connected by a flat plate portion 59d parallel to the XY plane. As shown in FIG. 12, a flat plate part 59e parallel to the XY plane is provided at each end in the +Z direction of the operation plate 59a, the side plate parts 59bL, 59bR, and the flat plate part 59f.
A plurality of reinforcing ribs extending in the depth direction are provided on the flat plate portion 59d between the flat plate portion 59f and the connecting plate 59c.
The flat plate portion 59e forms the bottom of the groove V in the +Z direction. The depth of the groove V in the vicinity of the operation plate 59a is not particularly limited as long as the user's non-first finger can be engaged with the operation plate 59a. For example, the depth of the groove V may be greater than or equal to the length from the fingertip of the user's non-first finger to the first joint.

As shown in FIG. 13, the height in the vertical direction from the flat plate portion 59d to the connecting plate 59c is slightly narrower than the gap from the top surface portion 58a to the bottom plate portion 60a when the base portion 67a is assembled.
On the other hand, the end portion of the operation plate 59a in the −Z direction protrudes further in the −Z direction than the flat plate portion 59d. Therefore, the side plate portions 59bL and 59bR, which cover the ends in the width direction of the groove V, move from the −Z direction surface of the flat plate portion 59d toward the −Z direction tip of the operation plate 59a as they advance in the +Y direction. It has an inclined part that is inclined in the -Z direction.
Portions of the operation plate 59a and side plate portions 59bL and 59bR that protrude in the −Z direction from the flat plate portion 59d protrude from the notch portion 60e of the lower cover 60 in the −Z direction.

The operating portion 59A is used to move the operating member 59 in the depth direction by the user placing a finger inserted into the groove V on the operating plate 59a and operating the position of the operating plate 59a in the depth direction.
The operating member 59 is moved from a first position, which is located furthest in the −Y direction, indicated by a solid line in FIG. It is movable in the depth direction between a second position located in the direction.
Hereinafter, when explaining the operating member 59 in the assembled state, unless otherwise specified, the operating member 59 will be described as being disposed at the first position.

The operating portion 59A is disposed at a position facing a portion of the third rear wall portion 58b parallel to the ZX plane (hereinafter referred to as a flat plate portion of the third rear wall portion 58b) in the depth direction. For example, in the example shown in FIG. 10, the operation section 59A operates on the flat plate part of the third rear wall part 58b in the range from the end in the +X direction to the vicinity of the end in the -X direction of the flat plate part of the third rear wall part 58b. is facing.
Therefore, when viewed from above, the center axis O _59A , which passes through the center of the width of the operating portion 59A in the width direction and extends in the depth direction, is shifted from the center axis Od of the elevator main body 58 in the −X direction.
The side plate portion 59bR faces the end of the flat plate portion of the third rear wall portion 58b in the +X direction in the depth direction. Thereby, the side plate portion 59bR is located further in the −X direction than the second side wall portion 58dRb in the width direction.
On the other hand, the position of the side plate portion 59bL in the width direction is substantially the same as the position of the first side wall portion 58dLb in the width direction.

According to such an arrangement, the operation plate 59a of the operation portion 59A faces only the flat plate portion of the third rear wall portion 58b in the depth direction. Therefore, in the second position indicated by the two-dot chain line, the operation plate 59a can approach to a position where there is almost no gap between the operation plate 59a and the inner surface of the third rear wall portion 58b.
On the other hand, the operation plate 59a has a curved side surface portion that curves in the −Y direction as it advances in the +X direction, such as a circular arc portion toward the fifth side wall portion 58k on the third rear wall portion 58b or the fifth side wall portion 58k. , the end of the operation plate 59a in the +X direction hits the inner circumferential surface of the curved side surface. As a result, the movement stroke of the operating member 59 from the first position to the second position becomes smaller than in the example shown in FIG.
If the movement stroke of the operating member 59 can be increased, the spring constant of the biasing member 77, which will be described later, can be reduced, making the user's operation easier.

The arrangement of the operating section 59A at the first position is not particularly limited.
In the example shown in FIG. 10, the operation plate 59a of the operation section 59A is located at a position overlapping the fifth side wall 58k when viewed from the -X direction.
The position of the connecting plate 59c of the operating portion 59A is a position where it overlaps the fourth side wall portion 58m when viewed from the -X direction. More specifically, the position of the connecting plate 59c is slightly closer to the −Y direction than the connecting portion between the fifth side wall portion 58k and the fourth side wall portion 58m when viewed from the −X direction. The position of the connecting plate 59c is also a position facing substantially the center of the third side wall portion 58f when viewed from the -X direction.

As shown in FIGS. 11 and 12, the operating section 59X is a structure in the operating member 59 excluding the operating section 59A. The actuating portion 59X extends further in the −Y direction than the operating portion 59A, is formed in a thickness range from the flat plate portion 59d to the flat plate portion 59e, and has a generally rectangular shape in plan view.
As shown in FIG. 10, the actuating portions 59X have shapes that are plane symmetrical to each other with respect to a plane S that is parallel to the YZ plane passing through the central axis Od.
The actuating portion 59X includes a transmission member 59B, a reinforcing member 59D, and a driving member 59C.

The transmission members 59B are plate-shaped members extending in the −Y direction from the connecting plate 59c of the operating portion 59A, and are provided as a pair facing each other in the width direction. Since each transmission member 59B is plane symmetrical with respect to the plane S, the distance between the transmission member 59B and the first side wall portion 58dLb in the −X direction and the distance between the transmission member 59B and the second side wall portion 58dRb in the +X direction are equal to each other. .
On the other hand, the distance between the transmission member 59B and the side plate portion 59bL in the −X direction is larger than the distance between the transmission member 59B and the side plate portion 59bR in the +X direction.

As shown in FIG. 11, the reinforcing member 59D includes a connecting member 59i and reinforcing ribs 59i1, 59i2, and 59i3.
The connecting member 59i connects the ends of each transmission member 59B in the -Y direction in the width direction. The shape of the connecting member 59i is not particularly limited as long as it has enough rigidity to maintain a constant distance in the width direction between the ends of the transmission member 59B in the -Y direction. In the examples shown in FIGS. 11 and 12, it is a flat plate parallel to the XY plane. The plan view shape of the connecting member 59i is a rectangle long in the width direction.

The shape and number of reinforcing ribs 59i1, 59i2, and 59i3 are not particularly limited as long as they can reinforce the connecting member 59i.
In the example shown in FIG. 11, the reinforcing ribs 59i1, 59i2, and 59i3 all protrude in the -Z direction from the surface of the connecting member 59i in the -Z direction.
The reinforcing rib 59i1 is a wall extending in the -Z direction from the edge of the connecting member 59i in the -Y direction.
The reinforcing rib 59i2 extends in the +Y direction from the +Y direction surface of the reinforcing rib 59i1. The reinforcing ribs 59i2 consist of a pair of reinforcing ribs 59i2 facing each other across the center of the connecting member 59i in the width direction.
The reinforcing rib 59i3 is a wall extending in the −Z direction and the +Z direction from the +Y direction edge of the connecting member 59i.
Both ends of the reinforcing ribs 59i1 and 59i3 in the width direction are connected to each transmission member 59B, respectively.
The connecting member 59i and the reinforcing ribs 59i1 and 59i3 in the reinforcing member 59D fix the distance in the width direction of the end of each transmission member 59B in the -Y direction.

As shown in FIG. 12, a guide protrusion 59j1 protrudes from the -X direction transmission member 59B, and a guide protrusion 59j4 protrudes from the +X direction transmission member 59B from the connecting member 59i, respectively. The guide protrusions 59j1 and 59j4 each extend in the direction in which each transmission member 59B extends.
As shown in FIG. 10, the guide protrusions 59j1 and 59j4 are inserted into the guide parts 58q1 and 58q4, respectively, and can move forward and backward in the depth direction that is the extending direction of the guide parts 58q1 and 58q4.

As shown in FIG. 12, between each transmission member 59B, lattice portions 59hL and 59hR extending in the −Y direction from the connecting plate 59c toward the reinforcing member 59D are provided in this order in the +X direction. The lattice portions 59hL and 59hR connect the reinforcing member 59D and the operating portion 59A in the depth direction.
The lattice portions 59hL and 59hR have shapes that are symmetrical to each other with respect to the plane S.
A guide protrusion 59j2 parallel to the guide protrusion 59j1 protrudes in the +Z direction above the lattice portion 59hL and the connecting member 59i. A guide protrusion 59j3 parallel to the guide protrusion 59j1 protrudes in the +Z direction above the lattice portion 59hR and the connecting member 59i. Guide protrusions 59j2 and 59j3 each extend in the direction in which each transmission member 59B extends.
As shown in FIG. 10, the guide protrusions 59j2 and 59j3 are inserted into the guide parts 58q2 and 58q3, respectively, and can move forward and backward in the depth direction that is the extending direction of the guide parts 58q2 and 58q3.

As shown in FIG. 12, an opening T1L having a rectangular shape in plan view extends vertically between the transmission member 59B and the lattice portion 59hL in the -X direction. An opening T1R having a rectangular shape in plan view passes through in the vertical direction between the transmission member 59B and the lattice part 59hR in the +X direction.
The reinforcing rib 59i3 forms the inner circumferential surface of the openings T1L and T1R in the -Y direction. Inside the openings T1L and T1R, bar-shaped protrusions 59g protruding from the reinforcing ribs 59i3 in the +Y direction are provided, respectively.
An opening T2 having a rectangular shape in plan view passes through the grid portions 59hR and 59hL in the vertical direction.

As shown in FIG. 10, in the vicinity of the inner surface in the +Y direction of the openings T1R and T1L of the operation member 59, the locking portions 58p of the housing portion 58A are arranged at positions facing each of the rod-shaped projections 59g in the depth direction. has been done.
An end portion in the -Y direction of a biasing member 77 made of a compression coil spring is fitted into the outer peripheral portion of each rod-shaped projection 59g.
The end portion of each biasing member 77 in the +Y direction is engaged with the locking portion 59p from the +Y direction while each biasing member 77 is compressed.
As a result, the operating member 59 is urged in the -Y direction through the reinforcing rib 59i3. Therefore, the operating member 59 is moved to the first position when no external force acts on the operating portion 59A.

A cushioning material fixing plate 58v of the housing portion 58A is arranged near the inner surface of the opening T2 in the +Y direction. A cushioning material 78 is fitted into the insertion groove 58v1 of the cushioning material fixing plate 58v.
The buffer material 78 is located at a position where the operating portion 59A moving toward the first position can abut the connecting plate 59c without colliding with protrusions from the upper surface portion 58a such as the plurality of guide portions 58q and the locking portions 58p. It is located in
As the cushioning material 78, rubber, elastomer, or the like having vibration-proofing properties is used. Therefore, when the operating portion 59A collides with the cushioning material 78 while moving to the first position, the kinetic energy of the operating portion 59A is dissipated. Thereby, for example, impact force, impact noise, etc. from the operating portion 59A are suppressed.

The drive member 59C is provided at each end of each transmission member 59B in the -Y direction.
Each drive member 59C moves a pair of locking portions 70, which will be described later, in the width direction by moving forward and backward in the depth direction together with each transmission member 59B. Each drive member 59C protrudes to the outside of the side surface 59k of each transmission member 59B. The distance between the side surfaces 59k in the width direction is equal to the distance between the positions of the drive members 59C. Hereinafter, the interval between the arrangement positions of each drive member 59C in the width direction will be referred to as an arrangement distance.
The shape of each driving member 59C viewed from the −Z direction is not particularly limited as long as the locking portions 70 can be moved in the width direction in response to the movement of the driving member 59C in the depth direction.
In the example shown in FIG. 10, the protruding shape of each drive member 59C is an isosceles triangle with the apex 59m facing the guide portion 58t when viewed from the −Z direction. A convex arc-shaped curved surface is formed on the top m of each drive member 59C. However, each drive member 59C may be, for example, a scalene triangle with each base angle on the side surface 59k being an acute angle, or may be a semicircle.
In the first position of the operating member 59, each top portion 59m faces the center of the guide portion 58t in the width direction.

With such a configuration, the reinforcing member 59D is disposed between the pair of drive members 59C when viewed from the width direction, and fixes the distance between the pair of drive members 59C in the width direction.

The operation member 59 may be formed of an assembly in which at least one of the operation section 59A, the transmission member 59B, the drive member 59C, and the reinforcing member 59D is separable, or the operation section 59A, the transmission member 59B, the drive member 59C, and the reinforcing member 59D may be integrally formed.
The material of the operating member 59 may be metal, resin, or materials other than metal and resin. The operating member 59 may be formed of a composite of multiple types of materials.
It is more preferable that the operating member 59 includes a resin molded product in which an operating portion 59A, a transmission member 59B, a driving member 59C, and a reinforcing member 59D are integrally molded.

The operating portion 59X of the operating member 59 is arranged symmetrically with respect to a central axis O _59C that extends in the depth direction through a midpoint that bisects the arrangement distance in the width direction in plan view. The shape of the actuating portion 59X is plane symmetrical with respect to a plane parallel to the YZ plane that includes the central axis O _59C .
Further, since the central axis O _59C coincides with the central axis Od, the actuating portion 59X is also plane symmetrical with respect to the plane S passing through the center of the narrow portion 67d of the platform portion 67a.
When the operating member 59 moves, the actuating portion 59X receives an external force that is symmetrical with respect to the plane S from the biasing member 77 described above and the locking portion 70 described later, so that it can resist these external forces in a well-balanced manner. .
Since the actuating part 59X is arranged at the center of the narrow part 67d in the width direction, compared to the case where the actuating part 59X is eccentric with respect to the plane S, there is a dead body that is not used for moving the actuating part 59X in the narrow part 67d of the platform part 67a. less space. Therefore, the space within the narrow portion 67d can be effectively utilized. The width of the actuating portion 59X that occupies the width of the narrow portion 67d in the width direction can be relatively increased. Thereby, the rigidity of the actuating portion 59X can be improved.

On the other hand, the operating section 59A is arranged asymmetrically with respect to the plane S. The operating section 59A protrudes in the -X direction from the -X direction side surface of the operating section 59X. Therefore, the central axis O _59A (first central axis) of the operating portion 59A in the width direction is eccentric in the −X direction with respect to the central axis O _59C (second central axis). That is, the center axis O _59A is eccentric toward the rotation axis _OL of the refrigerator compartment door 12 than the center axis O _59C .

By arranging the operating portion 59A eccentrically near the rotational axis _OL in this manner, the width in the width direction (in the example shown in FIG. 10, the side plate portions 59bL and 59bR The distance between the drive members (hereinafter referred to as the operable width) is wider than the arrangement distance of the drive member 59C.
In this way, by eccentrically moving the operating portion 59A in the −X direction within the length range of the flat plate portion of the third rear wall portion 58b, the operation portion 59A can be operated within the length range of the flat plate portion of the third rear wall portion 58b. The possible range can be increased. At this time, the movement stroke of the operating portion 59A in the depth direction can be increased.
When the operable width becomes larger, the user has a wider selection range when placing his/her finger during operation, and thus operability is improved.

Next, the locking portion 70 will be explained. The locking portions 70 are arranged on both sides of the base portion 67a in the width direction and move forward and backward in the width direction.
As shown in FIG. 10, the shape and arrangement position of each locking portion 70 are plane symmetrical with respect to the plane S. An example of the locking portion 70 arranged in the −X direction will be described below.
FIG. 14 is a sectional view taken along line F14-F14 in FIG. 10.

As shown in FIG. 14, the locking portion 70 includes a first holder 71, a locking member 73, a biasing member 74, and a second holder 75.

The first holder 71 holds the locking member 73 so as to be movable in the −X direction. An opening is formed in the tip plate 71a of the first holder 71, which is provided in the -X direction, through which the end of the locking member 73 in the -X direction can be inserted.
A biasing member 72 that biases the first holder 71 in the +X direction is arranged between the tip plate 71a and the first side wall portion 58dLb. For example, a compression coil spring may be used as the biasing member 72.

The locking member 73 has a main body portion 73a extending in the −X direction, and a flat plate portion 73c provided at an end of the main body portion 73a in the +X direction and protruding outward from the main body portion 73a.
An inclined surface 73b is formed at the tip of the main body portion 73a in the −X direction, and is inclined in the +X direction as it advances in the +Z direction from a lower surface 73f parallel to the horizontal plane.
The flat plate portion 73c has a function of preventing the distal end plate 71a from coming off from the opening. An end portion of a biasing member 74 that biases the locking member 73 in the −X direction is engaged with an end surface of the flat plate portion 73c in the +X direction. For example, a compression coil spring may be used as the biasing member 74.
The end of the locking member 73 in the -X direction is inserted into the guide hole 58u so that it can move forward and backward.

The second holder 75 is fixed to the end of the first holder 71 in the +X direction, and constitutes the end of the locking portion 70 in the +X direction.
As shown in FIG. 10, a chevron-shaped protrusion 75a that is convex in the +X direction when viewed from the -Z direction is formed at the end of the second holder 75 in the +X direction. The chevron shape of the protrusion 75a is an isosceles triangle with the apex 75b rounded into a convex arc. However, the shape of the protrusion 75a is not limited to this. For example, the protrusion 75a can have various shapes similar to the shape of the drive member 59C in plan view.
As shown in FIG. 14, the end of the second holder 75 in the −X direction is connected to the end of the first holder 71 in the +X direction. A biasing member 74 is accommodated inside the first holder 71 and the second holder 75 so as to be expandable and retractable.

The operation of the locking portion 70 will be explained.
FIG. 15 is an explanatory diagram of the operation of the locking portion in the first embodiment. FIG. 16 is an explanatory diagram of the operation of the door container in the first embodiment.
In the first position of the operating member 59 shown in FIG. 14, the top 75b of the second holder 75 and the top 59m of the drive member 59C are in contact with each other. At this time, the biasing member 72 is compressed between the tip plate 71a and the first side wall portion 58dLb.
The locking member 73 is urged by the urging member 74 to advance in the −X direction and protrudes outward beyond the guide hole portion 58u.
In this state, when the tip of the locking member 73 in the −X direction is pressed in the +X direction with a force greater than the urging force of the urging member 74, the locking member 73 moves in the +X direction. For example, as shown in FIG. 15, the tip of the locking member 73 can move until it is retracted into the guide hole 58u.

When the operating member 59 is moved toward the second position by the user, each drive member 59C moves in the +Y direction, as shown in FIG. The first holder 71 and the second holder 75, which are biased by the biasing member 72, move inside the housing portion 58A in conjunction with the movement of the drive member 59C.
When the operating member 59 reaches the second position, the top 75b of the protrusion 75a comes into contact with the side surface 59k of the transmission member 59B. Each locking member 73 moves in the width direction together with the first holder 71 and the second holder 75, and retracts into the guide hole 58u.
When the user releases his/her hand from the operation plate 59a, the operation member 59 moves in the -Y direction due to the urging force of the urging member 77, so the operation member 59 returns to the first position and locks each locking portion 70. The member 73 returns to the state protruding from the guide hole 58u.

Next, the container body 57 will be explained.
As shown in FIG. 4, the container main body 57 is removably placed on a lifting platform 67. When placed, the container main body 57 is supported from below by the lifting table 67.
As shown in FIG. 6, the container main body 57 has a bottom portion (second bottom portion) 57a, an upper wall portion 57u, and a lower wall portion 57s.

The bottom surface portion 57a and the top wall portion 57u are box-shaped as a whole with an upward opening, and objects are accommodated on the bottom surface portion 57a surrounded by the top wall portion 57u.
The bottom surface portion 57a has a plate shape that can be placed on the top surface portion 58a of the lifting platform 67. The shape of the bottom surface portion 57a in plan view is a concave polygonal shape close to a rectangle that overlaps the top surface portion 58a of the lifting platform 67 from above.
The upper wall portion 57u extends to a certain height from the upper surface of the bottom portion 57a.

The upper wall portion 57u includes a first rear wall portion 57eL, a first side wall portion 57dL, a front wall portion 57c, a second side wall portion 57dR, and a second rear wall portion 57eR in the −Y direction.
The first rear wall portion 57eL, the first side wall portion 57dL, the front wall portion 57c, the second side wall portion 57dR, and the second rear wall portion 57eR are the first rear wall portion 58eL and the first side wall of the lifting platform main body 58, respectively. It is a wall body extending in the +Z direction from the upper surface of the bottom surface portion 57a along the inside of the portion 58dL, the front wall portion 58c, the second side wall portion 58dR, and the second rear wall portion 58eR.

A projecting edge portion 57h extending in the −Y direction is formed at the upper end of the front wall portion 57c.
A protrusion 57i extending in the width direction protrudes from the protruding edge 57h.
Projecting edge portions 57gL and 57gR extending outward in the width direction are formed at the upper ends of the first side wall portion 57dL and the second side wall portion 57dR, respectively.

A locking protrusion 57j that protrudes outward from the first side wall portion 57dL and extends in the −Z direction is provided below the intermediate portion of the projecting edge portion 57gL in the depth direction. The locking protrusion 57j positions the container body 57 in the depth direction by locking from above into the groove 58j of the first side wall portion 58dL when the container body 57 is mounted on the lifting table 67.
The protrusion height of the locking protrusion 57j from the first side wall portion 57dL should be such that it does not come into contact with protrusions from the ribs 61C, 61D such as the rail portion 64 when the door container 56A is attached to the rear member 53. Bye.
A locking protrusion 57j is formed on the second side wall portion 57dR and has a position and shape that are symmetrical with respect to a plane parallel to the YZ plane that bisects the space between the first side wall portion 57dL and the second side wall portion 57dR. There is.

The distance in the vertical direction from the lower surface of the bottom surface portion 57a to the lower surface of each of the projecting edges 57gL, 57h, and 57gR is as follows: The height is equal to or slightly larger than the heights of the front wall portion 58c, the second side wall portion 58dR, and the second rear wall portion 58eR. As a result, as shown in FIG. 13, when the container main body 57 is mounted on the lifting table 67, the bottom surface portion 57a is placed on the top surface portion 58a.
Similar to the relationship between the projecting edge 57h and the upper end of the front wall 58c shown in FIG. It is located in contact with or slightly above the upper end of the wall portion 58eR.
As shown in FIG. 13, the length from the upper end of the protrusion 57i to the lower end of the locking protrusion 58DR is h4, which is larger than h2. The same applies to the length from the upper end of the protrusion 57i to the lower end of the locking protrusion 58DL.

The upper wall portion 57u has a third side wall portion 57f, a third rear wall portion 57b, a fifth side wall portion 57k, and a fourth side wall portion 57m in the +Y direction.
The third side wall portion 57f, the third rear wall portion 57b, the fifth side wall portion 57k, and the fourth side wall portion 57m are the third side wall portion 58f and the third rear wall portion 58b of the lifting platform main body 58, respectively, in plan view. , the fifth side wall portion 58k, and the fourth side wall portion 58m.
The third side wall portion 57f is connected to the end of the first rear wall portion 57eL in the -X direction. The fourth side wall 57m is connected to the end of the second rear wall 57eR in the +X direction.

The lower wall portion 57s is formed by a third side wall portion 57f, a third rear wall portion 57b, a fifth side wall portion 57k, and a fourth side wall portion 57m of the upper wall portion 57u, each extending in the −Z direction. Therefore, the third side wall portion 57f, the third rear wall portion 57b, the fifth side wall portion 57k, and the fourth side wall portion 57m have external shapes of side and front surfaces extending in the vertical direction at the +Y direction end of the container body 57. It is a wall that forms a
The position in the vertical direction of the lower end of the lower wall portion 57s when loaded on the lifting platform 67 is the position of the lower end of the third side wall portion 58f, the third rear wall portion 58b, the fourth side wall portion 58m, and the fifth side wall portion 58k. equal. Therefore, the lower wall portion 57s covers the third side wall portion 58f, the third rear wall portion 58b, the fourth side wall portion 58m, and the fifth side wall portion 58k from the outside. For example, when the lower wall portion 57s is formed of an opaque material, the third side wall portion 58f, the third rear wall portion 58b, the fourth side wall portion 58m, and the fifth side wall portion 58k are hidden by the lower wall portion 57s. . This improves the aesthetic appearance of the inner surface of the refrigerator compartment door 12.

In the present embodiment, in the door container _56A , a fifth side wall 57k and a fifth side wall 57k and a third A curved side surface portion consisting of four side wall portions 57m is formed.
The side surface portion consisting of the fifth side wall portion 57k and the fourth side wall portion 57m is a corner portion relatively far from the rotation axis _OL , and is curved with a radius of curvature that approximates the rotation radius _rL of the refrigerator compartment door 12. It is more preferable. In this case, when the refrigerator compartment door 12 is rotated, interference between the container body 57 and the refrigerator compartment door 13 can be prevented, and the volume of the storage space of the container body 57 can be maximized.
In the example shown in FIG. 10, the corner that is relatively far from the rotation axis _OL is formed by the fifth side wall 57k, so the radius of curvature of the fifth side wall 57k is approximately equal to the rotation radius _rL . .

Next, the operation of the door container 56A will be explained.
As shown by the solid line in FIG. 10, when no operating force is applied to the operating member 59 by the user, the operating member 59 is located at the first position. In this case, since the second holder 75 of each locking portion 70 comes into contact with the top portion 59m of the drive member 59C, the entire locking portion 70 has moved outward in the width direction. Each locking member 73 projects from the guide hole 58u between the locking projection 58F and the guide projection 58CR, and between the locking projection 58F and the guide projection 58CL.
At this time, the reinforcing member 59D is arranged between each drive member 59C with each transmission member 59B interposed therebetween when viewed from the width direction. Therefore, even if each drive member 59C receives a reaction force inward in the width direction from each locking portion 70, each transmission member 59B is suppressed from deflecting within the XY plane compared to the case without the reinforcing member 59D. . Thereby, the arrangement distance of each drive member 59C is kept constant, and the position of each top portion 59m that contacts each locking portion 70 is stabilized. As a result, the amount of protrusion of the locking member 73 from each guide hole 58u is stabilized.

When the operating member 59 is placed in the first position, when an external force acts on the tip of each locking member 73 and the locking member 73 is pushed toward the inside of the housing portion 58A, the biasing member 74 is compressed, and each locking member 73 is retracted into the guide hole 58u.
When the external force is released, the elastic restoring force of the biasing member 74 causes the locking member 73 to protrude outward from the guide hole 58u.

As shown in FIG. 13, for example, the user places the non-first finger fb into the groove V in the operating section 59A, applies operating force in the +Y direction to the operating plate 59a, and moves the operating member 59 in the -Y direction. can be done. For example, while pressing the third rear wall portion 57b with the first finger fa, the non-first finger fb is pulled in the +Y direction. In this case, the non-first finger fb and the first finger fa move to grip the third rear wall portion 57b and the operating plate 59a, making it easier to apply operating force.
As shown in FIG. 10, in this embodiment, the operation section 59A inside the housing section 58A extends in the width direction along the third rear wall section 58b, so that all Even with the non-first finger fb open, it can be inserted with plenty of room.
Therefore, the user can easily insert the non-first finger fb into the groove V even when the groove V is not visible. Furthermore, since the user can insert the four non-first fingers fb into the groove V, it is easier to apply the operating force more stably in this case.
The user can apply operating force to an appropriate position in the longitudinal direction of the groove V by, for example, reducing the gap between the non-first fingers fb or reducing the number of fingers inserted into the groove V. . When the user inserts the non-first finger fb into the groove V, the user can also move the non-first finger fb to a position where it can be easily operated in the longitudinal direction of the groove V.

When the operation part 59A moves in the +Y direction, the entire operation member 59 including each drive member 59C connected to the operation part 59A by each transmission member 58B and the reinforcing member 59D connecting each drive member 59C moves in the +Y direction. Move to. At this time, since the plurality of guide protrusions 59j1, j2, j3, and j4 of the operating member 59 are inserted into the plurality of guide parts 58q, the operating member 59 is aligned parallel to the +Y direction along the plurality of guide parts 58q. Can be moved.
Therefore, even if the position on which the operating force is applied varies in the longitudinal direction of the operating plate 59a, rotation of the operating member 59 in the XY plane is suppressed, so that the operating member 59 can be smoothly translated in parallel.

As shown in FIG. 16, when the operating member 59 moves to the second position, each of the locking portions 70, which is biased toward the inside of the guide portion 58t in the width direction by the biasing member 72, is entirely attached to the housing portion 58A. Move inward. As a result, each locking member 73 retreats into the guide hole portion 58u. When the user releases the non-first finger fb placed on the operation plate 59a, the operation member 59 returns to the first position, and each locking member 73 projects to the outside of each guide hole 58u.

Next, the operation of attaching and detaching the door container 56A to the rear member 53A and the movement of the door container 56A in the vertical direction will be described.
17 and 18 are explanatory diagrams of the operation of the door container in the first embodiment. Since FIGS. 17 and 18 illustrate the configuration in the -X direction, the movement of the illustrated members will be explained below. However, the operations of members arranged symmetrically in the +X direction (not shown) are also similar.

To attach the door container 56A to the rear member 53A, the user holds the lifting platform 67 from which the container body 57 has been removed, as shown by the two-dot chain line in FIG. 59 to the second position.
The user holds the lifting table 67 in this state and inserts the lifting table 67 into the gap G1 with the front wall portion 58c facing the rear member 53A. The vertical opening size of the gap G1 is h3. h3 is greater than the length h2 from the flat plate portion 58EL to the lower end of the locking protrusion 58DL on the side surface in the width direction of the lifting platform 67, and is the length from the upper end of the protrusion 57i on the door container 56A to the lower end of the locking protrusion 58DL. The size should be smaller than h4.
Therefore, the lifting table 67 can pass through the gap G1 in the −Y direction and move close to the inner surface 53a. However, the door container 56A cannot pass through the gap G1 in the -Y direction.

After that, the locking protrusion 58DL is inserted into the groove g1 from above.
Since the locking member 73 of the locking portion 70 of the lifting platform 67 is retracted inside the housing portion 58A, the locking member 73 does not interfere with the uneven structure of the rail portion 64.
Therefore, the user can move the elevator platform 67 in the vertical direction along the rail portion 64, for example, while holding the upper surface portion 58a of the elevator platform 67 and the operation plate 59a. At this time, since the fingertip of the non-first finger fb can be pressed against the lower surface of the flat plate portion 59e, it is easy to apply a force to move the lifting table 67 in the vertical direction. By inserting all the non-first fingers fb into the groove V, the range for supporting the lifting table 67 from below is expanded, so that it is easy to stably support the lifting table 67.

In this manner, when the guide protrusion 58CL and the locking protrusion 58DL are accommodated in the groove g1, the guide protrusion 58CL and the locking protrusion 58DL are hidden by the rail portion 64 and are almost invisible when viewed from the -Y direction. In particular, the beauty of the inner surface of the refrigerator compartment door 12 is improved by making the locking protrusion 58DL that protrudes below the elevator platform 67 invisible.

As shown by the solid line in FIG. 17, when the user releases his or her finger from the operation plate 59a at a position where the locking portion 70 faces the first rail portion 64a, the operation member 59 moves to the first position, and the locking portion Each of the 70 locking members 73 protrudes outside the guide hole 58u. As a result, the locking member 73 protrudes into the recessed portion of the first rail portion 64a that is vertically sandwiched between the locking plates 64e. When the user releases his/her hand from the lifting table 67, the locking member 73 locks from above to the locking plate 64e closest to the lifting table 64 in the -Z direction due to the gravity acting on the lifting table 67.
Thereby, the vertical position of the lifting table 67 is fixed. The fixed position of the lifting platform 67 is determined by the positions of the plurality of locking plates 64e. The fixing position of the lifting platform 67 in the vertical direction can be changed in multiple stages based on the arrangement pitch of the plurality of locking plates 64e.

Thereafter, the container body 57 is placed on the 67th platform. As shown by the solid line in FIG. 17, the user holds the container body 57 in his hand and moves it above the lifting platform 67 to lower the container body 57. Since the width of the end of the container body 57 in the −Y direction is narrower than the gap in the width direction between the rail portions 64, the user can move the container body 57 at any position above the lifting platform 67. can be inserted between the ribs 61.
After moving the container body 57 to a position where each locking projection 57j can be inserted into each groove 58j of the lifting table 67 from above, the user places the container body 57 on the upper surface portion 58a. Thereby, the container main body 57 is attached to the lifting platform 67 (see the two-dot chain line in FIG. 17). The position of the container body 57 on the lifting table 67 is fixed by inserting each locking projection 57j into each groove 58j from above.
In this way, the door container 56A is attached near the inner surface 53a of the rear member 53A. The user can similarly attach the door container 56B above the door container 56A.

In this embodiment, the door containers 56A and 56B attached to the rear member 53A can be moved in the vertical direction by performing a push-up operation and a lock release operation, which will be described below. In this embodiment, since the configurations of the door containers 56A and 56B are similar to each other, an example in which the door container 56A is moved will be described below.

The push-up operation is an operation in which the user applies force in the +Z direction to the lifting platform 67 without operating the operating member 59 to move the lifting platform 67 in the +Z direction. For example, the user may press up the door container 56A by placing his hand on the lower surface of the platform 67a.
During the push-up operation, when the inclined surface 73b of the locking member 73 and the sloped rib 64fa come into contact with each other, the locking member 73 is pushed inward by the horizontal component of the reaction from the sloped rib 64fa.
When the locking member 73 passes over the upper locking plate 64e, the locking member 73 projects outward from the guide hole 58u. At this time, if the user releases his/her hand and stops the push-up operation, the locking member 73 locks onto the locking plate 64e that has been climbed over from above.
By such a push-up operation, the user can move the door container 56A in the +Z direction and lock the elevator platform 67 on the upper locking plate 64e.
In the push-up operation, the door container 56A can be locked higher, but cannot be lowered.

The unlocking operation is an operation for forcibly releasing the locking in the vertical direction by the locking member 73. In this operation, the user moves the operating member 59 to the second position. In this case, each locking member 73 is retracted inside the guide hole 58u, so the user can freely move the door container 56A within the movable range.
In this embodiment, since the fifth side wall portion 57k at the end in the +X direction is curved, the volume of the accommodation space of the container body 57 in plan view is smaller in the −X direction than in the plane S. The volume is smaller. Therefore, the center of gravity of the door container 56A containing the contents is more likely to be eccentric in the -X direction than in the plane S.
In this embodiment, the groove V on which the user touches is eccentric with respect to the plane S in the −X direction. Therefore, the user can easily support the door container 56A at a position close to the center of gravity of the door container 56A, making it easy to move up and down when releasing the lock.
Furthermore, in this embodiment, since the groove V is formed to be long in the width direction along the third rear wall portion 58b, the user can adjust the position of the finger on the operation plate 59a within the range of the groove V. Can be moved as appropriate. This makes it possible to move the hand to a position where it is easy to support the door container 56A, depending on the center of gravity of the door container 56A containing the contents.

When the user releases the operation plate 59a, the locking member 73 protrudes and locks onto the nearest lower locking plate 64e. Thereby, the movement position of the door container 56A etc. is fixed.

Here, the movable range of the door containers 56A and 56B will be explained.
As shown in FIG. 18, the lowest lowered position of the door container 56A is a position where the lower end of the locking protrusion 58DL locks on the lowered position regulating portion 53d from above. The same applies when the door container 56B is arranged below the door container 56A.
By providing the descending position regulating portion 53d, even if the user's supporting force weakens during the unlocking operation and the door container 56A falls, the door container 56A will not fall out below the groove g1. can be prevented.

The door containers 56A, 56B can move vertically within a range where the first rail portion 64a and the locking member 73 can face each other, and can fix their vertical positions.
For example, in the case of the door container 56B shown in FIG. 18, the protrusion 57i can be raised to a position where it comes into contact with the lower surface 61g of the rib 61F, as shown by the two-dot chain line. However, the length h4 from the tip of the protrusion 57i in the +Z direction to the end surface of the locking protrusion 58DL in the -Z direction is longer than the size h3 of the gap G1. Therefore, when the user tries to move the door container 56B in the +Y direction, the locking protrusion 58DL interferes with the upper end of the second rail portion 64b, so the user cannot pull out the door container 56B in the +Y direction. Therefore, it is possible to prevent the door container 56B from detaching from the rear member 53 due to momentum when the door container 56B containing the contents is moved upward vigorously.

For example, if the user is unable to fully support the door container 56B after moving the door container 56B above the first rail portion 64a, if the user is unable to fully support the door container 56B with his or her finger on the operation panel 59a, 56B may fall.
In this case, the door container 56B descends until the locking protrusion 58DL abuts against the flat plate portion 58EL of the lower door container 56A. The distance between the bottom plate portion 60a, which is the lower surface of the platform portion 67a, and the upper end of the container body 57 of the door container 56A is h1 depending on the length of the locking protrusion 58DL. For example, if h1 has a value larger than the thickness of the hand, the user's hand can be prevented from being caught between the base portion 67a of the door container 56B and the container body 57 of the door container 56A.
The locking protrusion 58DL of the door container 56B is provided outside the container body 57 of the door container 56A in the width direction, and comes into contact with the flat plate portion 58EL of the door container 56A, which is supported from below by the guide projection 58CL. Since the flat plate portion 58EL can be formed to have a wider width than the first side wall portion 57dL in a plan view, it is possible to prevent damage to the container main body 57 of the door container 56A and the elevator platform 67 due to the impact of dropping.

In such a movement operation of the door container 56A, the user can perform the operation by placing his or her finger on the operation member 59 using the operation portion 59A, which is wider than the width of the actuating portion 59X of the operation member 59. Even if the width in the horizontal direction is narrow, the user's operability is improved.

The operation of the refrigerator 1A has been explained above, focusing on the actions of the door containers 56A and 56B, but the door containers 54A and 54B are different except for the width and the position of the curved corner of the container body and the lifting platform. , has the same configuration as the door containers 56A and 56B. Therefore, the door containers 54A, 54B have the same function as the door containers 56A, 56B.

As explained above, according to the refrigerator 1A and the door containers 56A, 56B, 54A, and 54B of the present embodiment, even if the door container is small with a narrow bottom area, vertical movement and attachment/detachment from the door can be easily performed. can be done easily.

At the upper ends of the first side wall portion 58dL, the front wall portion 58c, and the second side wall portion 58dR, projecting edge portions 57gL, 57h, and 57gR similar to those in the first embodiment are provided with the same shape and position as in the first embodiment. is formed. In this embodiment, the protrusion 57i is not formed on the protrusion 57h.

The first side wall portions 58dL and 58dLb in this embodiment are formed with a flat plate portion 58EL, a guide projection 58CL, a locking projection 58DL, and a locking projection 58F similar to those in the first embodiment.
The second side wall portions 58dR and 58dRb in this embodiment are formed with a flat plate portion 58ER, a guide projection 58CR, a locking projection 58DR, and a locking projection 58F similar to those in the first embodiment.

The bottom portion 167 is similar to the base portion 67a except that it includes a lower portion 157a of the container body 157 instead of the housing portion 58A. That is, the bottom portion 167 is covered with a lower cover 60 similar to the first embodiment. A pair of locking parts 70, an operation member 59 (not shown), a biasing member 77, and a cushioning material 78 are arranged between the upper surface part 58a and the lower cover 60, as in the first embodiment. ing.

Like the door container 56A in the first embodiment, the door container 156 having such a configuration is detachable from the rear member 53A, and can be moved in the vertical direction along the rail portion 64 when attached. However, since the door container 156 does not have the protrusion 57i, it can be attached and detached through the gap G1.
According to the door container 156 of this embodiment and the refrigerator 1B provided with the door container 156, it has the same effect|action as the door container 56A and refrigerator 1A in 1st Embodiment.
