Description

Embodiments of the present invention relate to a refrigerator.

It is known that a door container of a storage room in a refrigerator is provided with a door container that can be moved up and down and is removable from the door. For example, the bottom surface of the door container is provided with a locking mechanism for locking the door and an operating member for operating 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 turning radius of the revolving door. As a result, the area of the bottom surface portion on which the operating member is provided is narrowed, which limits the size of the operating member. If the operating member is small, the locking mechanism may not be easily operated.

[First Embodiment]
The refrigerator of the first embodiment will be described.
FIG. 1 is a front view showing a refrigerator of the first embodiment in a state where the door is opened.
The overall configuration of the refrigerator 1A of the first embodiment shown in FIG. 1 will be described. However, the refrigerator 1A does not have 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 refrigerating room doors 12, 13 (doors, revolving doors), and a plurality of doors 11.
The housing 10 includes, for example, an inner box, an outer box, and a heat insulating material.
The inner box is made of, for example, a synthetic resin, and has a shape recessed from the front side to the rear side at a plurality of places. Each recess in the inner box forms a plurality of storage chambers 27. In the example shown in FIG. 1, the plurality of storage chambers 27 include a refrigerator compartment 27A, a vegetable compartment 27B, an upper freezing chamber 27C, a lower freezing chamber 27D, and an ice making chamber 27E. The refrigerating room 27A, the vegetable room 27B, the upper freezing room 27C, and the lower freezing room 27D are arranged in this order from the upper side to the lower side. The ice making chamber 27E is located on the left side of the upper freezing chamber 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 has a rectangular parallelepiped shape forming outer surface portions on three sides except the front side of the housing 10. The outer box is formed of, for example, a metal or a composite material of a metal and a 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. As a result, the housing 10 has a heat insulating property.

In the housing 10, various members forming the refrigerator main body 5 together with the housing 10 are arranged between the inner box and the outer box. Examples of the member forming the refrigerator body 5 include a cooling unit for forming cold air, a flow path forming member for forming a flow path for circulating cold air between each storage chamber 27 and the cooling unit, and cold air through the flow path. Examples thereof include a cooling fan sent to the storage chamber 27 and a control board for controlling the operation of the cooling unit and the cooling fan.

The temperature inside the refrigerator compartment 27A is maintained lower than that of the vegetable compartment 27B and higher than that of the upper freezing chamber 27C and the lower freezing chamber 27D. Inside the refrigerating room 27A, for example, shelves for partitioning the room, chilled room containers, and the like are arranged. The front surface of the refrigerator compartment 27A is covered with openable doors 12 and 13 that open to the left and right.

As shown in FIG. 1, the refrigerating chamber doors 12 and 13 are doors provided for opening and closing the refrigerating chamber 27A. The refrigerating chamber door 12 covers the left side of the opening of the refrigerating chamber 27A when closed. The refrigerating chamber door 13 covers the right side of the opening of the refrigerating chamber 27A when closed. The end of the refrigerating room door 12 in the + X direction and the end of the refrigerating room door 13 in the −X direction face each other with a slight gap in the width direction when closed. The gap at the time of closing between the refrigerating chamber doors 12 and 13 in the lateral width direction is closed by, for example, a rotary partition plate 68 provided on the refrigerating chamber door 12.
The width dimensions of the refrigerating chamber doors 12 and 13 in the width 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 refrigerating chamber door 12 is smaller than the width dimension of the refrigerating chamber door 13.

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

The plurality of doors 11 are doors provided for opening and closing the vegetable compartment 27B, the upper freezing chamber 27C, the lower freezing chamber 27D, and the ice making chamber 27E. The vegetable room door 11B, the upper freezing room door 11C, the lower freezing room door 11D, and the ice making room door 11E cover the front surfaces of the vegetable room 27B, the upper freezing room 27C, the lower freezing room 27D, and the ice making room 27E, respectively.

The temperature inside the vegetable compartment 27B is maintained higher than that in the refrigerator compartment 27A. Inside the vegetable compartment 27B, for example, a vegetable compartment container for accommodating a storage such as vegetables and a guide rail for moving the vegetable compartment container in the depth direction are provided.
The front surface of the vegetable compartment 27B is covered with a drawer-type vegetable compartment door 11B that can be opened and closed.

The temperature inside the upper freezing chamber 27C, the lower freezing chamber 27D, and the ice making chamber 27E is maintained at a temperature at which the storage can be frozen. Inside the upper freezing chamber 27C, the lower freezing chamber 27D, and the ice making chamber 27E, for example, a small freezing chamber, a freezing chamber container for accommodating storage for freezing, and a guide rail for moving the freezing chamber container in the depth direction. , Etc. are provided.
The front surfaces of the upper freezing chamber 27C, the lower freezing chamber 27D and the ice making chamber 27E are covered with a drawer-type upper freezing chamber door 11C, a lower freezing chamber door 11D and an ice making chamber door 11E so as to be openable and closable.

The configuration of each storage chamber 27 and each door 11 described above is an example, and is not limited to the above example. For example, the door 11 of the storage chamber 27 other than the refrigerating chamber 27A may be a revolving door, or may be a double-door revolving door.

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

The door containers 56A and 56B arranged above the lower door container 56C are vertically movable and detachably attached to the inner surface portion forming the inner surface in the + Y direction in the refrigerating room door 12. The positions of the door containers 56A and 56B can be fixed in the vertical direction at a plurality of locations within the movement range in the vertical direction.
Here, the vertical movement pitch and movement range of the door containers 56A and 56B are not particularly limited.
The lower door container 56C may be detachably attached to the inner surface portion of the refrigerating chamber door 12, or may be fixed to the inner surface portion.

The door containers 54A and 54B arranged above the lower door container 54C are vertically movable and detachably attached to the inner surface portion forming the inner surface in the + Y direction in the refrigerating room door 13. The positions of the door containers 54A and 54B can be fixed in the vertical direction at a plurality of locations within the movement range in the vertical direction.
Here, the vertical movement pitch and movement range of the door containers 54A and 54B are not particularly limited.
The lower door container 54C may be detachably attached to the inner surface portion of the refrigerating chamber door 13, or may be fixed to the inner surface portion.

Next, the detailed configuration of the refrigerating room doors 12 and 13 will be described. However, since the refrigerating room doors 12 and 13 have the same basic structure except that the arrangement position and the width dimension are different, the example of the refrigerating room door 12 will be mainly described below.
FIG. 2 is a perspective view showing the refrigerator compartment door 12 in the first embodiment.
As shown in FIG. 2, the refrigerating chamber door 12 includes, for example, an outer member 50A, a gasket 55A, and a rotary partition plate 68.

The outer member 50A is formed in a box shape. The "box shape" as used herein also includes a flat box shape. The outer member 50A has, for example, a frame body 51A, a front plate 52A, and a rear surface member 53A (inner surface portion).

The frame body 51A is a rectangular frame when viewed from the −Y direction. The frame body 51A includes an upper side member 51a, a lower side member 51b, and side side members 51c and 51d. In the state where the refrigerating room door 12 is closed, the upper side member 51a has a plate shape along the width direction and the depth direction, and forms the upper surface of the refrigerating room door 12. The lower side member 51b has a plate shape along the width direction and the depth direction, and forms the lower surface of the refrigerating room door 12. The side members 51c and 51d have a plate shape 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 body 51A is made of, for example, a synthetic resin.
The lower side member 51b is formed with a groove portion 8 recessed in the + Z direction. The groove portion 8 is formed at the end portion of the lower side member 51b in the + X direction. The groove 8 can be touched by the user when the refrigerating room door 12 is opened.

The front plate 52A is attached so as to close the opening in the −Y direction of the frame body 51A, and is located at the front end portion of the refrigerating chamber door 12, respectively. The front plate 52A is a rectangular plate member along the frame 51A, and forms the front surface of the refrigerating chamber door 12. The front plate 52A is, for example, a glass plate. However, the front plate 52A is not limited to the glass plate, and may be formed of a synthetic resin or another material. The front plate 52A may be a flat plate or a curved plate. Hereinafter, the front plate 52A will be described with an example of a flat plate.

The rear surface member 53A is attached to the frame body 51A from the side opposite to the front plate 52A, and is located at the rear end portion of the refrigerating chamber door 12. The outer shape of the rear surface member 53A seen from the −Y direction is a rectangle along the frame body 51A. The rear surface member 53A is made of, for example, a synthetic resin.
The rear surface 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 projects in the + Y direction toward the refrigerating chamber 27A from the frame 51A and the inner surface 53a in a state where the refrigerating chamber door 12 closes the opening of the refrigerating chamber 27A (when closed). The space between the rear surface member 53A and the front plate 52A and the inside of the convex shape of the rib 61 are filled with a foamed heat insulating material.
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 12 and the housing 10.
In the present specification, the term "rib" is a name for convenience of explanation, and broadly means a portion protruding rearward from the rear surface member 53A, and is not limited to a specific shape or action.

The gasket 55A 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 12 and the housing 10 when the refrigerating chamber door 12 is closed. ..
The gasket 55A forms an annular shape surrounding the outer periphery of the frame body 51A and is attached to the rear surface member 53A. The method of attaching the gasket 55A is not particularly limited. For example, the gasket 55A may be attached by uneven fitting between the mounting convex portion provided on the gasket 55A and the mounting concave portion provided on the rear surface member 53A.

The rotary partition plate 68 extends in the vertical direction along the gasket 55A in the + Y direction of the gasket 55A adjacent to the side member 51c in the refrigerating chamber door 12. The upper and lower ends of the rotary partition plate 68 are rotatably connected to the rear surface member 53A in a horizontal plane via a rotation support member (not shown).
When the refrigerating chamber door 12 shown in FIG. 2 is opened, the rotary partition plate 68 rotates toward the rib 61 near the side member 51c, and when viewed from the −Y direction, the rotary partition plate 68 is more − than the side member 51c. It is located in the X direction.
When the refrigerating chamber door 12 is closed, the rotary partition plate 68 rotates clockwise when viewed from the −Z direction and protrudes in the + X direction from the side member 51c. As a result, a flat plate portion is formed so that the gasket 55A and the gasket 55B, which will be described later, of the refrigerating chamber door 13 can be in close contact with each other.

Here, the detailed configuration of the rear surface member 53A will be described.
FIG. 3 is a perspective view showing the rear member 53A of the refrigerator compartment door 12.
As shown in FIG. 3, the rib 61 extends in the horizontal direction along the upper side member 51a, the rib 61G extending in the horizontal direction along the lower side member 51b, and the rib 61 extending in the vertical direction along the side member 51c. It has a rib 61C and a rib 61D extending 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 project in the + Y direction from the rib 61F. The amount of protrusion of the rib 61F is such that when the door containers 56A and 56B are moved in the + Z direction, the door containers 56A and 56B can be prevented from coming off.

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

A step portion 53c, a rail portion 64, and a locking projection 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.

When the door containers 56A and 56B, which will be described later, are moved in the vertical direction, the rail portion 64 guides the door containers 56A and 56B in the vertical direction with the position in the depth direction restricted.
The rail portion 64 projects from the side surface S1 in the −X direction, and extends vertically in parallel with 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 protruding height of the rail portion 64 from the side surface S1 may be different from or the same as the protruding 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 face 53cx, which is the end face of the step portion 53c in the −X direction. In this case, the end surface 53cx of the stepped portion 53c approaches the side surface of the door containers 56A and 56B described later in the + X direction, and can function as a guide surface in the lateral width direction of the door containers 56A and 56B.

A concave 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 portion of the rail portion 64. The convex portion p may be deleted if a space for arranging parts can be secured inside the rib 61C.

The upper end of the rail portion 64 is formed at a position lower 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. Between the lower end of the rail portion 64 and the lower end of the step portion 53c, a lowering position restricting portion 53d protruding inward of the concave groove g1 is provided. The lowering position regulating unit 53d is provided to regulate the lowering position of the door container 56B.
The shape of the lowering position regulating portion 53d is not particularly limited as long as the lowering position of the door container 56B can be regulated. In the example shown in FIG. 3, the descending position restricting portion 53d is a plate connecting the lower end of the rail portion 64 and the end surface 53cy of the step portion 53c, and closes the concave groove g1 from below.
The vertical arrangement position of the lowering position regulating portion 53d is an appropriate position according to the lowest lowering position of the door container 56B.
A reinforcing rib 64fb for reinforcing the descending position regulating portion 53d against an external force acting from above is provided between the lower surface of the descending position regulating portion 53d and the side surface S1.

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 and 56B, which will be described later, and regulates the vertical movement positions of the door containers 56A and 56B in multiple stages.
The first rail portion 64a has 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 extends to the second rail portion 64b like the first guide 64c.
The tips 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 project from the side surface S1 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 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, 17 plurality of locking plates 64e are arranged.
The tips of the locking plates 64e in the protruding direction are located on the same plane as the tips of the first guide 64c and the second guide 64d located on both sides of the locking plate 64e in the width direction.

The upper end plate 64g is a plate extending in the depth direction between the first guide 64c and the second guide 64d and projecting vertically from the side surface S1. The upper end plate 64g is located above the plurality of locking plates 64e, and is separated upward from the uppermost locking plate 64e at a pitch substantially equal to the pitch between the respective 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 vertically from the side surface S1. The lower end plate 64k is located below the lowermost locking plate 64e, and is separated downward from the lowermost locking plate 64e at a wider interval than the pitch between the respective locking plates 64e.

The plurality of inclined ribs 64fa are provided on the lower surface side of each locking plate 64e excluding 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 the lower surface of the upper end plate 64g, and are arranged at intervals in the depth direction from each other. Further, the inclined ribs 64fa are 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 seen from the −Y direction is a triangle that inclines toward the side surface S1 from each tip of each locking plate 64e and the upper end plate 64g in the −X direction in the −Z direction.

With such a configuration, a plurality of convex portions are arranged in the vertical direction at substantially equal intervals from the lower side to the upper side inside the first rail portion 64a. The plurality of convex portions are formed by the inclined portion 64j formed at the tip of the inclined rib 64fa in the −X direction, the tip surface of the locking plate 64e, and the locking surface formed on the upper surface of the locking plate 64e and extending in the horizontal direction. It is formed by 64i and. Relative concave portions are formed between the convex portions protruding in the X direction from the side surface S1.

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. As a result, the side plate portion 59bR is located in the −X direction with respect to the second side wall portion 58dRb in the lateral width direction.
On the other hand, the position of the side plate portion 59bL in the lateral width direction is substantially the same as the position of the first side wall portion 58dLb in the lateral width direction.

According to such an arrangement, the operation plate 59a of the operation unit 59A faces only the flat plate portion of the third rear wall portion 58b in the depth direction. Therefore, the operation plate 59a can approach to a position where there is almost no gap with the inner surface of the third rear wall portion 58b at the second position indicated by the alternate long and short dash line.
On the other hand, the operation plate 59a is a curved side surface portion that curves in the −Y direction as it advances in the + X direction, such as an arc portion toward the fifth side wall portion 58k or the fifth side wall portion 58k in the third rear wall portion 58b. When facing the above, the end portion of the operation plate 59a in the + X direction hits the inner peripheral surface of the curved side surface portion. As a result, the movement stroke of the operating member 59 from the first position to the second position is smaller than that of the example shown in FIG.
If the moving stroke of the operating member 59 can be increased, the spring constant of the urging member 77, which will be described later, can be reduced, so that the user's operation becomes easier.

The arrangement of the operation unit 59A at the first position is not particularly limited.
In the example shown in FIG. 10, the position of the operation plate 59a of the operation unit 59A is a position overlapping with the fifth side wall portion 58k when viewed from the −X direction.
The position of the connecting plate 59c of the operating portion 59A is a position overlapping with 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 portion 59X is a structure in the operating member 59 excluding the operating portion 59A. The operating portion 59X extends in the −Y direction from the operating portion 59A and is formed in a thickness range from the flat plate portion 59d to the flat plate portion 59e, and the plan view shape is substantially rectangular as a whole.
As shown in FIG. 10, the actuating portion 59X has a shape symmetrical with respect to a plane S parallel to the YZ plane passing through the central axis Od.
The actuating portion 59X has a transmission member 59B, a reinforcing member 59D, and a driving member 59C.

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

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

The shape and number of the reinforcing ribs 59i1, 59i2, 59i3 are not particularly limited as long as the connecting member 59i can be reinforced.
In the example shown in FIG. 11, the reinforcing ribs 59i1, 59i2, and 59i3 all project from the surface of the connecting member 59i in the −Z direction in the −Z direction.
The reinforcing rib 59i1 is a wall body extending in the −Z direction from the edge in the −Y direction of the connecting member 59i.
The reinforcing rib 59i2 extends in the + Y direction from the surface of the reinforcing rib 59i1 in the + Y direction. The reinforcing ribs 59i2 are composed of a pair facing each other with the center of the connecting member 59i in the lateral width direction interposed therebetween.
The reinforcing rib 59i3 is a wall body extending in the −Z direction and the + Z direction from the edge of the connecting member 59i in the + Y direction.
Both ends of the reinforcing ribs 59i1 and 59i3 in the lateral 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 lateral width direction of the end portion of each transmission member 59B in the −Y direction.

As shown in FIG. 12, a guide protrusion 59j1 protrudes from the transmission member 59B in the −X direction and a guide protrusion 59j4 protrudes from the connecting member 59i in the + Z direction on the transmission member 59B in the + X direction. The guide protrusions 59j1 and 59j4 extend in the extending direction of each transmission member 59B, respectively.
As shown in FIG. 10, the guide protrusions 59j1 and 59j4 are inserted into the guide portions 58q1 and 58q4, respectively, and can advance and retreat in the depth direction which is the extending direction of the guide portions 58q1 and 58q4, respectively.

As shown in FIG. 12, between the transmission members 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 plane-symmetrical with respect to the plane S.
A guide protrusion 59j2 parallel to the guide protrusion 59j1 protrudes in the + Z direction on the lattice portion 59hL and the connecting member 59i. A guide protrusion 59j3 parallel to the guide protrusion 59j1 protrudes in the + Z direction on the lattice portion 59hR and the connecting member 59i. The guide protrusions 59j2 and 59j3 extend in the extending direction of each transmission member 59B, respectively.
As shown in FIG. 10, the guide protrusions 59j2 and 59j3 are inserted into the guide portions 58q2 and 58q3, respectively, and can advance and retreat in the depth direction which is the extending direction of the guide portions 58q2 and 58q3, respectively.

As shown in FIG. 12, a rectangular opening T1L in a plan view penetrates vertically between the transmission member 59B and the grid portion 59hL in the −X direction. A rectangular opening T1R in a plan view penetrates vertically between the transmission member 59B and the grid portion 59hR in the + X direction.
The reinforcing rib 59i3 forms an inner peripheral surface in the −Y direction at the openings T1L and T1R. Inside the openings T1L and T1R, rod-shaped protrusions 59g protruding from the reinforcing ribs 59i3 in the + Y direction are provided, respectively.
A rectangular opening T2 in a plan view penetrates vertically between the lattice portions 59hR and 59hL.

As shown in FIG. 10, in the vicinity of the inner surface of the opening T1R and T1L of the operating member 59 in the + Y direction, the locking portion 58p of the housing portion 58A is arranged at a position facing each rod-shaped protrusion 59g in the depth direction. Has been done.
An end portion of a biasing member 77 made of a compression coil spring in the −Y direction is fitted in the outer peripheral portion of each rod-shaped protrusion 59 g.
The end portion of each urging member 77 in the + Y direction is locked to the locking portion 59p in a compressed state from the + Y direction.
As a result, the operating member 59 is urged in the −Y direction through the reinforcing ribs 59i3. Therefore, the operation member 59 is moved to the first position when no external force acts on the operation unit 59A.

A cushioning material fixing plate 58v of the housing portion 58A is arranged in the vicinity of the inner surface of the opening portion T2 in the + Y direction. The cushioning material 78 is fitted in the insertion groove 58v1 of the cushioning material fixing plate 58v.
The cushioning material 78 is located at a position where the operating portion 59A moving toward the first position can come into contact with the connecting plate 59c without colliding with the protrusions from the upper surface portion 58a such as the plurality of guide portions 58q and the locking portions 58p. Is located in.
As the cushioning material 78, rubber, an elastomer or the like having anti-vibration properties is used. Therefore, when the operation unit 59A moves to the first position and collides with the cushioning material 78, the kinetic energy of the operation unit 59A is dissipated. As a result, for example, the impact force and the impact sound from the operation unit 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 back and forth in the depth direction together with each transmission member 59B to move a pair of locking portions 70, which will be described later, in the width direction. Each drive member 59C projects to the outside of the side surface 59k of each transmission member 59B. The distance between the side surfaces 59k in the lateral width direction is equal to the distance between the arrangement positions of the drive members 59C. Hereinafter, the distance between the arrangement positions of the drive members 59C in the horizontal width direction is referred to as an arrangement distance.
The shape of each drive member 59C seen from the −Z direction is not particularly limited as long as the locking portion 70 can be moved in the lateral width direction corresponding to the drive member 59C moving in and out in the depth direction.
In the example shown in FIG. 10, the protruding shape of each driving member 59C is an isosceles triangle with the top portion 59m facing toward the guide portion 58t when viewed from the −Z direction. A convex arcuate curved surface is formed on the top m of each drive member 59C. However, each drive member 59C may be, for example, an isosceles triangle having an acute angle at each base angle on the side surface 59k, or may be a semicircle.
At the first position of the operating member 59, each top portion 59m faces the center of the guide portion 58t in the lateral width direction.

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

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

The operating portion 59X of the operating member 59 is arranged line-symmetrically with respect to the central axis O _59C extending in the depth direction through the midpoint that bisects the arrangement distance in the width direction in a plan view. The shape of the actuating portion 59X is plane symmetric with respect to a plane parallel to the YZ plane including the central axis O _59C .
Further, since the central axis O _59C coincides with the central axis Od, the operating portion 59X is also plane symmetric with respect to the plane S passing through the center of the narrow portion 67d of the base portion 67a.
Since the operating portion 59X receives a plane-symmetrical external force with respect to the plane S from the above-mentioned urging member 77 and the locking portion 70 described later when the operating member 59 moves, it is possible to resist these external forces in a well-balanced manner. ..
Since the actuating portion 59X is arranged at the center of the narrow width portion 67d in the lateral width direction, the dead portion not used for moving the actuating portion 59X in the narrow width portion 67d of the base portion 67a is compared with the case where the actuating portion 59X is eccentric with respect to the plane S. There is less space. Therefore, the space in the narrow width portion 67d can be effectively used. The width of the operating portion 59X occupying the width in the width direction of the narrow width portion 67d can be relatively widened. Thereby, the rigidity of the operating portion 59X can be improved.

On the other hand, the operation unit 59A is arranged asymmetrically with respect to the plane S. The operating portion 59A protrudes in the −X direction from the side surface of the operating portion 59X in the −X direction. Therefore, the central axis O _59A (first central axis) of the operation unit 59A in the horizontal width direction is eccentric in the −X direction with respect to the central axis O _59C (second central axis). That is, the central axis O _59A is _eccentric to the direction closer to the rotation axis OL of the refrigerating chamber door 12 than the central axis O _59C .

By eccentrically arranging the operation unit 59A toward the rotation axis OL in this way, the width in the lateral width direction in which the operation force can be applied to the operation unit 59A (in the example shown in FIG. 10, the side plate portions _59bL and 59bR The distance between them (hereinafter referred to as the operable width) is wider than the arrangement distance of the drive member 59C.
In this way, by eccentricizing the operation unit 59A in the −X direction within the range of the length of the flat plate portion of the third rear wall portion 58b, the operation unit 59A is operated within the range of the length of the flat plate portion of the third rear wall portion 58b. The possible width can be increased. At that time, it is possible to take a large movement stroke of the operation unit 59A in the depth direction.
When the operable width becomes large, the range of selection when the user puts a finger at the time of operation is widened, so that the operability is improved.

Next, the locking portion 70 will be described. The locking portions 70 are arranged on both side portions of the base portion 67a in the lateral width direction, and advance and retreat in the lateral width direction.
As shown in FIG. 10, the shape and arrangement position of each locking portion 70 are plane symmetric with respect to the plane S. Hereinafter, an example of the locking portion 70 arranged in the −X direction will be described.
FIG. 14 is a cross-sectional view taken along the line F14-F14 in FIG.

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

The first holder 71 holds the locking member 73 so as to be able to move forward and backward in the −X direction. The tip plate 71a provided in the −X direction of the first holder 71 is formed with an opening through which the end portion of the locking member 73 in the −X direction can be inserted.
An urging member 72 that urges 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 urging 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 portion of the main body portion 73a in the + X direction and protruding outward from the main body portion 73a.
At the tip of the main body portion 73a in the −X direction, an inclined surface 73b that inclines in the + X direction as it advances in the + Z direction from the lower surface 73f parallel to the horizontal plane is formed.
The flat plate portion 73c has a function of preventing the tip plate 71a from coming off from the opening. An end portion of the urging member 74 that urges the locking member 73 in the −X direction is locked to the end surface of the flat plate portion 73c in the + X direction. For example, a compression coil spring may be used as the urging member 74.
The end of the locking member 73 in the −X direction is inserted into the guide hole portion 58u so as to be able to advance and retreat.

The second holder 75 is fixed to the end portion of the first holder 71 in the + X direction, and constitutes the end portion of the locking portion 70 in the + X direction.
As shown in FIG. 10, at the end of the second holder 75 in the + X direction, a chevron-shaped protrusion 75a convex in the + X direction when viewed from the −Z direction is formed. The chevron shape of the protrusion 75a is an isosceles triangle in which the top 75b is 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 plan view shape of the drive member 59C.
As shown in FIG. 14, the end portion of the second holder 75 in the −X direction is connected to the end portion of the first holder 71 in the + X direction. A urging member 74 is housed inside the first holder 71 and the second holder 75 so as to be expandable and contractible.

The operation of the locking portion 70 will be described.
FIG. 15 is an operation explanatory view of the locking portion in the first embodiment. FIG. 16 is an operation explanatory view of the door container in the first embodiment.
At the first position of the operating member 59 shown in FIG. 14, the top portion 75b of the second holder 75 and the top portion 59m of the driving member 59C are in contact with each other. At this time, the urging 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 from 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 larger 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 retracts into the guide hole portion 58u.

When the operating member 59 is moved toward the second position by the user, each driving member 59C moves in the + Y direction as shown in FIG. The first holder 71 and the second holder 75 urged by the urging member 72 move to the inside of the housing portion 58A in conjunction with the movement of the driving member 59C.
When the operating member 59 reaches the second position, the top portion 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 lateral width direction together with the first holder 71 and the second holder 75, and retracts inside the guide hole portion 58u.
When the user releases the operation plate 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 returns to the first position and the locking portions 70 are locked. The member 73 returns to a state of protruding from the guide hole portion 58u.

Next, the container body 57 will be described.
As shown in FIG. 4, the container main body 57 is detachably placed on the elevating table 67. At the time of mounting, the container body 57 is supported from below by the elevating table 67.
As shown in FIG. 6, the container main body 57 has a bottom surface portion 57a, an upper wall portion 57u, and a lower wall portion 57s.

The bottom surface portion 57a and the upper wall portion 57u have a box shape that opens upward as a whole, and the contents are housed on the bottom surface portion 57a surrounded by the upper wall portion 57u.
The bottom surface portion 57a has a plate shape that can be placed on the top surface portion 58a of the elevating table 67. The shape of the bottom surface portion 57a in a plan view is a concave polygonal shape close to a rectangle that overlaps the upper surface portion 58a of the elevating table 67 from above.
The upper wall portion 57u extends from the upper surface of the bottom surface portion 57a to a certain height.

The upper wall portion 57u has 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 portion of the elevator 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.

At the upper end of the front wall portion 57c, a protruding edge portion 57h extending in the −Y direction is formed.
A ridge 57i extending in the lateral width direction protrudes on the ridge portion 57h.
At the upper ends of the first side wall portion 57dL and the second side wall portion 57dR, ridge portions 57gL and 57gR extending outward in the lateral width direction are formed, respectively.

A locking projection 57j that protrudes outward from the first side wall portion 57dL and extends in the −Z direction is provided on the lower side of the intermediate portion in the depth direction of the ridge portion 57gL. When the locking projection 57j is mounted on the elevating table 67, the container body 57 is positioned in the depth direction by locking the container body 57 in the concave groove 58j of the first side wall portion 58dL from above.
The protruding height of the locking protrusion 57j from the first side wall portion 57dL should be such that the door container 56A does not come into contact with the protrusions from the ribs 61C and 61D such as the rail portion 64 when the door container 56A is attached to the rear surface member 53. Just do it.
The second side wall portion 57dR is formed with a locking projection 57j having a position and shape symmetrical with respect to a plane parallel to the YZ plane that bisects between the first side wall portion 57dL and the second side wall portion 57dR. There is.

The vertical distances from the lower surface of the bottom surface portion 57a to the lower surfaces of the ridge portions 57gL, 57h, and 57gR are the first rear wall portion 58eL and the first side wall portion 58dL from the upper surface of the upper surface portion 58a of the elevating table main body 58. It is equal to or slightly larger than the height 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, the bottom surface portion 57a is placed on the top surface portion 58a in a state where the container body 57 is mounted on the elevating table 67.
Similar to the relationship between the upper ends of the ridge portion 57h and the front wall portion 58c shown in FIG. 13, the ridge portions 57 gL and 57 gR are the first rear wall portion 58eL, the first side wall portion 58dL, the second side wall portion 58dR, and the second rear wall portion. It is in contact with or slightly above the upper edge of the wall 58eR.
As shown in FIG. 13, the length from the upper end of the ridge 57i to the lower end of the locking projection 58DR is h4, which is larger than h2. The same applies to the length from the upper end of the ridge 57i to the lower end of the locking projection 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, in plan view, the third side wall portion 58f and the third rear wall portion 58b of the elevating platform main body 58, respectively. , A wall body extending in the + Z direction from the peripheral edge of the bottom surface portion 57a along the outer peripheral surface of the fifth side wall portion 58k and the fourth side wall portion 58m.
The third side wall portion 57f is connected to the end portion of the first rear wall portion 57eL in the −X direction.
The fourth side wall portion 57m is connected to the end portion of the second rear wall portion 57eR in the + X direction.

The lower wall portion 57s is formed by extending 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 of the upper wall portion 57u in the −Z direction, respectively. 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 are outer shapes of the side surface and the front surface extending in the vertical direction at the + Y direction end portion of the container body 57. It is a wall body that forms.
The positions of the lower ends of the lower wall portion 57s when loaded on the elevating table 67 in the vertical direction are the positions of the lower ends 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 made of an opaque material, the lower wall portion 57s hides 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. .. As a result, the aesthetic appearance of the inner surface of the refrigerating room door 12 is improved.

In the present embodiment, in the door container 56A, the fifth side wall portion 57k and the fifth side wall portion 57k from the third rear wall portion 57b toward the second rear wall portion _57eR at the ends in the + X direction and the + Y direction far from the rotation axis OL. A curved side surface portion composed of four side wall portions 57 m is formed.
The side surface portion including 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 close to the rotation radius r _L of the refrigerating chamber door 12. Is more preferable. In this case, it is possible to prevent interference between the container body 57 and the refrigerating room door 13 when the refrigerating room door 12 is rotated, and to maximize the volume of the accommodation space of the container body 57.
In the example shown in FIG. 10, since the corner portion relatively far from the rotation axis OL is formed by the fifth side wall portion _57k , the radius of curvature of the fifth side wall portion 57k is substantially equal to the rotation radius r _L. ..

Next, the operation of the door container 56A will be described.
As shown by the solid line in FIG. 10, the operation member 59 is located at the first position when the operation force from the user is not applied to the operation member 59. In this case, since the second holder 75 of each locking portion 70 comes into contact with the top portion 59m of the driving member 59C, the entire locking portion 70 moves outward in the lateral width direction. Each locking member 73 projects from the guide hole portion 58u between the locking projection 58F and the guide projection 58CR and between the locking projection 58F and the guide projection 58CL, respectively.
At this time, the reinforcing member 59D is arranged between the driving members 59C when viewed from the lateral width direction with the transmission members 59B interposed therebetween. Therefore, even if each drive member 59C receives a reaction force from each locking portion 70 inward in the lateral width direction, the deflection of each transmission member 59B in the XY plane is suppressed as compared with the case where each drive member 59C does not have the reinforcing member 59D. .. As a result, the arrangement distance of each drive member 59C is kept constant, and the position of each top portion 59m in contact with each locking portion 70 is stabilized. As a result, the amount of protrusion of the locking member 73 from each guide hole portion 58u is stabilized.

In the state where the operating member 59 is arranged at the first position, an external force acts on the tip of each locking member 73, and when each locking member 73 is pushed toward the inside of the housing portion 58A, the urging member 74 is compressed and each locking member 73 retracts inside the guide hole 58u.
When the external force is released, the locking member 73 projects outward from the guide hole portion 58u due to the elastic restoring force of the urging member 74.

As shown in FIG. 13, for example, the user inserts the non-first finger fb into the concave groove V in the operation unit 59A and applies an operation force in the + Y direction to the operation plate 59a to move the operation member 59 in the −Y direction. Can be made to. 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 grip the third rear wall portion 57b and the operation plate 59a, so that the operation force can be easily applied.
As shown in FIG. 10, in the present embodiment, since the operation portion 59A in the housing portion 58A extends long in the lateral width direction along the third rear wall portion 58b, all the operation portions 59A in the longitudinal direction of the concave groove V. Even when the non-first finger fb is open, it can be inserted with a margin.
Therefore, the user can easily insert the non-first finger fb into the concave groove V even when the concave groove V cannot be seen. Further, since the user can insert the four non-first fingers fb into the concave groove V, it is easier to apply the operating force more stably in this case.
The user can apply an operating force to an appropriate position in the longitudinal direction of the concave groove V by, for example, reducing the gap between the non-first fingers fb or reducing the number of fingers inserted into the concave groove V. .. When the non-first finger fb is inserted into the concave groove V, the user can also move the non-first finger fb to a position that is easy to operate in the longitudinal direction of the concave groove V.

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

As shown in FIG. 16, when the operating member 59 moves to the second position, the entire locking portion 70 urged toward the inside of the guide portion 58t in the lateral width direction by the urging member 72 is the housing portion 58A. Move inward. As a result, each locking member 73 retracts into the guide hole portion 58u.
When the user releases the non-first finger fb hung 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 portion 58u.

Next, the operation of attaching / detaching the door container 56A to / from the rear surface member 53A and the operation of moving in the vertical direction will be described.
17 and 18 are operation explanatory views of the door container in the first embodiment. Since the configuration in the −X direction is illustrated in FIGS. 17 and 18, the movement of the illustrated member will be described below. However, the operation of the members symmetrically arranged in the + X direction (not shown) is also the same.

In order for the user to attach the door container 56A to the rear surface member 53A, as shown by a two-dot chain line in FIG. 17, the user has an elevating table 67 from which the container body 57 has been removed, and pulls the operation plate 59a in the + Y direction to attach the operation member. Move 59 to the second position.
The user holds the elevating table 67 in this state, and inserts the elevating table 67 into the gap G1 with the front wall portion 58c facing the rear surface member 53A. The size of the vertical opening of the gap G1 is h3. h3 is larger than the length h2 from the flat plate portion 58EL on the lateral side surface of the elevating table 67 to the lower end of the locking projection 58DL, and is the length from the upper end of the ridge 57i in the door container 56A to the lower end of the locking projection 58DL. The size is smaller than h4.
Therefore, the elevating 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 projection 58DL is inserted into the concave groove g1 from above.
Since the locking member 73 of the locking portion 70 of the elevating table 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, for example, the user can move the elevating table 67 in the vertical direction along the rail portion 64 while gripping the upper surface portion 58a and the operation plate 59a of the elevating table 67. 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 for moving the elevating table 67 in the vertical direction. By inserting all the non-first finger fb into the concave groove V, the range for supporting the elevating table 67 from below is widened, so that the elevating table 67 can be supported stably and easily.

As described above, in the state where the guide protrusion 58CL and the locking protrusion 58DL are housed in the concave groove g1, the guide protrusion 58CL and the locking protrusion 58DL are hidden by the rail portion 64 and hardly visible when viewed from the −Y direction. In particular, since the locking projection 58DL protruding below the elevator table 67 becomes invisible, the aesthetic appearance of the inner surface of the refrigerator compartment door 12 is improved.

As shown by the solid line in FIG. 17, when the user releases the finger from the operation plate 59a at the position where the locking portion 70 faces the first rail portion 64a, the operating member 59 moves to the first position and the locking portion Each locking member 73 of 70 projects to the outside of the guide hole portion 58u. As a result, the locking member 73 protrudes into the recess sandwiched in the vertical direction by the locking plate 64e in the first rail portion 64a. When the user releases the elevating table 67, the locking member 73 is locked to the nearest locking plate 64e in the −Z direction from above by the gravity acting on the elevating table 67.
As a result, the vertical position of the elevating table 67 is fixed. The fixed position of the lift 67 is determined by the positions of the plurality of locking plates 64e to be locked. The fixed position of the elevating table 67 in the vertical direction can be changed in multiple stages in units of arrangement pitches of the plurality of locking plates 64e.

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

In the present embodiment, the door containers 56A and 56B mounted on the rear surface member 53A can be moved in the vertical direction by performing the push-up operation and the unlocking operation described below. In the present embodiment, the configurations of the door containers 56A and 56B are similar to each other, and therefore, an example of moving the door container 56A will be described below.

The push-up operation is an operation in which the user applies a force in the + Z direction to the elevating table 67 without operating the operating member 59 to move the elevating table 67 in the + Z direction. For example, the user may put his / her hand on the lower surface of the base portion 67a to push up the door container 56A.
When the inclined surface 73b of the locking member 73 and the inclined rib 64fa come into contact with each other during the push-up operation, the locking member 73 is pushed inward by the horizontal component of the reaction from the inclined rib 64fa.
When the locking member 73 gets over the upper locking plate 64e upward, the locking member 73 projects outward from the guide hole portion 58u. At this time, if the user releases the hand and stops the pushing-up operation, the locking member 73 is locked to the overcoming locking plate 64e from above.
By such a push-up operation, the user can move the door container 56A in the + Z direction and lock the elevating table 67 on the locking plate 64e on the upper side.
In the push-up operation, the door container 56A can be locked to the upper side, but cannot be lowered.

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 moves the operation member 59 to the second position. In this case, since each locking member 73 retracts inside the guide hole portion 58u, the user can freely move the door container 56A within the movable range.
In the present embodiment, the volume of the accommodation space of the container body 57 in the plan view is in the + X direction rather than the volume in the −X direction than the plane S because the fifth side wall portion 57k of the end portion in the + X direction is curved. The volume is smaller. Therefore, the center of gravity of the door container 56A including the contained object is more likely to be eccentric in the −X direction than the plane S.
In the present embodiment, the concave groove V to which the user handles is eccentric in the −X direction with respect to the plane S. Therefore, the user can easily support the door container 56A at a position close to the center of gravity of the door container 56A, so that the user can easily move up and down when unlocking.
Further, in the present embodiment, since the concave groove V is formed long in the lateral width direction along the third rear wall portion 58b, the user can position the finger to be hung on the operation plate 59a within the range of the concave groove V. It can be moved as appropriate. This makes it possible to move the hand to a position where the door container 56A can be easily supported according to the center of gravity of the door container 56A including the container.

When the user releases the operation plate 59a, the locking member 73 protrudes and engages with the nearest lower locking plate 64e. As a result, the moving position of the door container 56A or the like is fixed.

Here, the movable range of the door containers 56A and 56B will be described.
As shown in FIG. 18, the lowermost lowering position of the door container 56A is a position where the lower end of the locking projection 58DL is locked to the lowering position regulating portion 53d from above. The same applies when the door container 56B is arranged below the door container 56A.
Since the lowering position regulating portion 53d is provided, even if the support force of the user is weakened during the unlocking operation and the door container 56A falls, the door container 56A falls below the concave groove g1. Can be prevented.

The door containers 56A and 56B can move in the vertical direction within a range in which the first rail portion 64a and the locking member 73 can face each other, and the positions in the vertical direction can be fixed.
For example, in the case of the door container 56B shown in FIG. 18, as shown by the alternate long and short dash line, the ridge 57i can rise to a position where it abuts on the lower surface 61g of the rib 61F. However, the length h4 from the tip of the ridge 57i in the + Z direction to the end face of the locking projection 58DL in the −Z direction is longer than the size h3 of the gap G1. Therefore, when the door container 56B is to be moved in the + Y direction, the locking projection 58DL and the upper end portion of the second rail portion 64b interfere with each other, so that the user cannot pull out the door container 56B in the + Y direction. Therefore, it is possible to prevent the door container 56B from coming off from the rear surface member 53 due to a momentum when the door container 56B containing the contained object is vigorously raised.

For example, if the user cannot support the door container 56B while the door container 56B is moved above the first rail portion 64a, the door container is held with the user's finger on the operation plate 59a. 56B may fall.
In this case, the door container 56B descends until the locking projection 58DL comes into contact with 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 base portion 67a, and the upper end of the container body 57 of the door container 56A is h1 according to the length of the locking projection 58DL. If h1 is, for example, a value larger than the thickness of the hand, it is possible to prevent the user's hand from being pinched between the base portion 67a of the door container 56B and the container body 57 of the door container 56A.
The locking projection 58DL of the door container 56B is provided on the outer side of the container body 57 of the door container 56A in the lateral width direction, and abuts on the flat plate portion 58EL of the door container 56A supported from below by the guide projection 58CL. Since the flat plate portion 58EL can be formed to have a width wider than that of the first side wall portion 57dL in a plan view, it is possible to prevent damage to the container body 57 and the elevating table 67 of the door container 56A due to the impact of dropping.

In such a movement operation of the door container 56A, the operation performed by the user by hooking the finger on the operation member 59 can be performed by the operation unit 59A wider than the width of the operation unit 59X of the operation member 59, so that the door container 56A can be performed. Even when the width in the width direction of the door is narrow, the operability of the user is improved.

The operation of the refrigerator 1A has been described above focusing on the actions of the door containers 56A and 56B, except that the width of the door containers 54A and 54B is different from the positions of the curved corners of the container body and the elevating table. , Has the same configuration as the door containers 56A and 56B. Therefore, the door containers 54A and 54B have the same functions as the door containers 56A and 56B.

As described above, according to the refrigerator 1A and the door containers 56A, 56B, 54A, 54B of the present embodiment, even a small door container having a narrow bottom area can be moved in the vertical direction and attached / detached from the door. Can be easily done.
