The detailed configuration of the right refrigerating chamber door 11Ab is left to be described later.

On the other hand, the vegetable compartment door 11B, the ice-making compartment door 11C, the freezer compartment door 11D, and the main freezer compartment door 11E are, for example, drawer-type doors. Vegetable compartment door 11B, ice making compartment door 11C, freezer compartment door 11D, and main freezer compartment door 11E are supported by guide rails 35 (only the left guide rail 35 is illustrated in vegetable compartment 27B and main freezer compartment 27E) so as to be able to be pulled out from frame 10.

As shown in fig. 2, the frame 10 has a1 st partition 28 and a2 nd partition 29. The 1 st partition 28 and the 2 nd partition 29 are, for example, partitions extending in a substantially horizontal direction. First partition 28 is located between refrigerating compartment 27A and vegetable compartment 27B, and partitions refrigerating compartment 27A and vegetable compartment 27B. On the other hand, the 2 nd partition 29 is located between the vegetable compartment 27B and the ice making compartment 27C and the small freezing compartment 27D, and partitions the vegetable compartment 27B from the ice making compartment 27C and the small freezing compartment 27D. No partition wall is provided between ice making compartment 27C and small freezing compartment 27D and main freezing compartment 27E.

The plurality of shelves 12 are disposed in the refrigerating compartment 27A.

The plurality of containers 13 includes: refrigerating room container 13A (for example, a fresh room container) disposed in refrigerating room 27A, 1 st and 2 nd vegetable room containers 13Ba and 13Bb disposed in vegetable room 27B, an ice making room container (not shown) disposed in ice making room 27C, small freezing room container 13D disposed in small freezing room 27D, and 1 st and 2 nd main freezing room containers 13Ea and 13Eb disposed in main freezing room 27E.

The flow path forming member 14 is disposed in the housing 10. The flow passage forming member 14 includes, for example, a1 st duct member 14A and a2 nd duct member 14B. The 1 st duct member 14A is provided along the rear wall 25 of the frame 10 and extends in the vertical direction. A1 st duct space S1, which is a passage through which cold air (air) flows, is formed between the 1 st duct member 14A and the rear wall 25 of the housing 10. Duct member 1a has a plurality of cold air outlet ports h1 opening toward refrigerating compartment 27A and cold air return port h2 opening toward vegetable compartment 27B. The 2 nd duct member 14B is provided along the rear wall 25 of the frame 10 and extends in the up-down direction. A2 nd duct space S2, which is a passage through which cold air (air) flows, is formed between the 2 nd duct member 14B and the rear wall 25 of the housing 10. The 2 nd duct member 14B has a plurality of cold air blow-out openings h3 that open toward the ice making compartment 27C, the small freezer compartment 27D, and the like, and a cold air return opening h4 that opens toward the main freezer compartment 27E.

First cooling unit 15A cools the air returned from vegetable compartment 27B via cold air return opening h2, and blows the cooled air into refrigerating compartment 27A from a plurality of cold air blow-out openings h 1. As a result, the cold air circulates through refrigerating room 27A and vegetable room 27B, and refrigerating room 27A and vegetable room 27B are cooled.

Cooling unit 2B cools the air returned from main freezer compartment 27E through cold air return opening h4, and blows the air from cold air blow-out opening h3 into ice making compartment 27C, small freezer compartment 27D, and main freezer compartment 27E. This causes air to circulate through ice making chamber 27C, small freezing chamber 27D, and main freezing chamber 27E, thereby cooling ice making chamber 27C, small freezing chamber 27D, and main freezing chamber 27E.

The compressor 45 is provided in a machine room at the bottom of the refrigerator 1, for example. The compressor 45 compresses the refrigerant gas for cooling of the storage chamber 27. The refrigerant gas compressed by compressor 45 is sent to cooling units 1 and 2, 15A and 15B through a heat pipe or the like.

The control board 16 comprehensively controls the entirety of the refrigerator 1. For example, control board 16 controls the operations of 1 st cooling unit 15A, 2 nd cooling unit 15B, and compressor 45 based on the detection results of temperature sensors provided in refrigerating room 27A, main freezing room 27E, and the like.

The detailed structure of the right refrigerating chamber door 11Ab will be described next.

Fig. 3 is a perspective view showing the right refrigerating compartment door 11 Ab. The right refrigerating chamber door 11Ab includes, for example, an outer frame member 50 and a gasket 55. The outer contour member 50 is formed in a box shape. The term "box-like" as used in this specification also includes flat box-like shapes. The outer frame member 50 includes, for example, a frame 51, a front plate 52 (see fig. 1), and a rear member 53.

On the inner surface side of the right refrigerating chamber door 11Ab, a plurality of cassettes 56 (door containers) and a cassette 59 (container) are detachably attached, the plurality of cassettes 56 being provided so that the arrangement position thereof is movable in the vertical direction, and the arrangement position of the cassette 59 being fixed in the vertical direction.

The number of cartridges 56 is not particularly limited. In the example shown in fig. 3, the box 56 includes a1 st box 56A (door container), a2 nd box 56B (door container), and a 3 rd box 56C (door container, container).

Box 59 is disposed near rib 61G at the lower end of rear surface member 53.

The frame body 51 is formed in a rectangular frame shape. The frame 51 includes an upper member 51a, a lower member 51b, a left member 51c, and a right member 51 d. The upper member 51a is plate-shaped along the lateral width direction and the depth direction, and forms the upper surface of the right refrigerating chamber door 11 Ab. The lower member 51b is plate-shaped along the lateral width direction and the depth direction, and forms the lower surface of the right refrigerating chamber door 11 Ab. The left member 51c is plate-shaped along the vertical direction and the depth direction, and forms the left side surface of the right refrigerating chamber door 11 Ab. The right member 51d is plate-shaped along the vertical direction and the depth direction, and forms the right side surface of the right refrigerating chamber door 11 Ab. The upper member 51a, the lower member 51b, the left member 51c, and the right member 51d are combined with each other to form a frame 51. The frame 51 is made of, for example, synthetic resin.

The front panel 52 (see fig. 1) is attached to the frame 51 and positioned at the front end of the right refrigerating chamber door 11 Ab. The front panel 52 is a panel member extending in the vertical direction and the lateral width direction, and forms the front surface of the right refrigerating chamber door 11 Ab. The front surface plate 52 is, for example, a glass plate. However, the front surface plate 52 is not limited to a glass plate, and may be formed of a synthetic resin or other material.

The front surface plate 52 may be a flat plate or a curved plate. The following description will be given of an example in which the front surface plate 52 is a flat plate.

The rear surface member 53 is attached to the frame body 51 from the opposite side of the front surface plate 52, and is located at the rear end portion of the right refrigerating chamber door 11 Ab. The outer shape of the rear surface member 53 viewed from the-Y direction is a rectangular shape along the frame body 51. The rear surface member 53 forms a rear surface of the right refrigerating chamber door 11 Ab. The rear surface member 53 is made of, for example, synthetic resin.

The rear surface member 53 has planar inner surface portions 53a and 53b along the front surface plate 52, and ribs 61 projecting rearward from the inner surface portions 53a and 53 b. In the example shown in fig. 3, the inner surface portions 53a, 53b are parallel to the front surface plate 52.

Rib 61 protrudes in the + Y direction (1 st direction) toward refrigerating room 27A (storage room) from frame 51 and inner surface portions 53a and 53b in a state where right refrigerating room door 11Ab is closed with respect to frame 10.

In the present description, the term "rib" is a name for convenience of description, and broadly refers to a portion protruding rearward from the rear surface member 53, and is not limited to a specific shape or action.

The rib 61 includes, for example, an annular rib group that is smaller than the outer shape of the frame 51. The "ring-like" referred to in the present specification includes not only a case where the ring-like is completely continuous over the entire circumference but also a case where the ring-like is partially interrupted by providing a cut.

The annular rib group of the ribs 61 includes a rib 61F extending in the lateral width direction along the upper member 51A, a rib 61G extending in the lateral width direction along the lower member 51b, ribs 61C and 61E extending in the vertical direction along the left member 51C, and ribs 61A and 61D extending in the vertical direction along the right member 51D.

The rib 61 includes a rib 61B extending in the vertical direction between the ribs 61A and 61C in the lateral width direction, in addition to the annular rib group.

The rib 61 protrudes rearward relatively largely. For example, the amount of rearward projection of the rib 61 is equal to or more than half the thickness of the outer shell member 50 in the depth direction excluding the rib 61. In the present embodiment, the protruding amount of the rib 61 is larger than the depth-direction thickness of the outer shell member 50 excluding the rib 61.

Although not particularly shown, the space between the rear surface member 53 and the front surface plate 52 and the inside of the convex shape in the rib 61 are filled with a foam heat insulator. As the foamed heat insulating material disposed on the rear side of the rear surface member 53, the same material as the above-described foamed heat insulating material 10c may be used.

The above-described annular rib group of ribs 61 is provided mainly for suppressing the cool air in refrigerating room 27A (storage room) from escaping from the gap between right refrigerating room door 11Ab and frame 10.

The washer 55 is attached to the rear surface member 53. Specifically, the rear surface member 53 has a throat portion 63, which is a recess recessed toward the inside of the right refrigerating chamber door 11 Ab. For example, the throat portion 63 is formed in a ring shape surrounding the outer periphery of the rib 61.

The washer 55 has a washer body 55a and a washer mounting portion 55 b. The gasket main body 55a is formed in a ring shape surrounding the outer peripheral side of the rib 61. When the right refrigerating chamber door 11Ab is closed with respect to the housing 10, the gasket main body 55a is interposed between the right refrigerating chamber door 11Ab and the housing 10 (or between the right refrigerating chamber door 11Ab and a rotation partition plate (not shown)), and closes a gap between the right refrigerating chamber door 11Ab and the housing 10 (or between the right refrigerating chamber door 11Ab and the rotation partition plate). The gasket mounting portion 55b is inserted into the inside of the throat portion 63 provided to the rear surface member 53 of the right refrigerating compartment door 11Ab, thereby being mounted to the throat portion 63. Thereby, the gasket 55 is fixed to the rear surface member 53.

The gasket 55 is provided for sealing so that cold air in the refrigerating chamber 27A (storage chamber) does not leak to the outside from between the right refrigerating chamber door 11Ab and the frame body 10 when the right refrigerating chamber door 11Ab is closed.

Here, the detailed structure of the rear surface member 53 will be described.

Fig. 4A and 4B are perspective views showing a rear surface member of the right refrigerating compartment door in the embodiment. Fig. 4A and 4B are different only in the direction of stereoscopic viewing. Fig. 5 is a sectional view of the refrigerator shown in fig. 4A taken along line F5-F5. Fig. 6 is an enlarged view of a portion F6 of the refrigerator shown in fig. 5. Fig. 7 is a sectional view of the refrigerator shown in fig. 4A taken along the line F7-F7.

As shown in fig. 4A and 4B, the inner surface portion 53a is formed in a range of about two thirds from the upper end of the rear surface member 53. The inner surface portion 53b is located slightly on the + Y direction side of the inner surface portion 53 a. The inner surface portion 53b is connected via a stepped portion at the lower end of the inner surface portion 53 a.

As shown in fig. 4A, the rib 61A protrudes in the + Y direction from the end of the inner surface portion 53a in the + X direction. The rib 61A extends from the rib 61F to the position of the boundary portion of the inner surface portions 53a, 53b in the up-down direction.

A protruding portion 61A is formed on the + X direction side at the front end portion of the rib 61A in the protruding direction. The protruding portions 61A protrude in the same direction as the ribs 61A and are formed over the entire length of the ribs 61A in the vertical direction. The protruding portions 61A form the foremost ends of the ribs 61A in the projecting direction.

In contrast, the front end of the rib 61F in the protruding direction is retracted in the-Y direction more than the rib 61A. Therefore, when viewed from above, a U-shaped opening that opens in the + Y direction is formed between the ribs 61A and 61B. The same applies to the ribs 61C and 61B.

In the example shown in fig. 4A, the amount of protrusion of the rib 61F from the inner surface portion 53a is substantially half of the amount of protrusion of the rib 61A from the inner surface portion 53 a. The amount of protrusion of the rib 61F may be larger than that described above as long as the attachment and detachment of the 1 st case 56A and the 2 nd case 56B described below are not hindered.

At the front end of the rib 61A in the projecting direction, a flat surface portion 61b is formed at a position lower than the front end of the ridge 61A in the projecting direction (position on the-X direction side) than the ridge 61A. The flat surface portion 61b is a flat surface parallel to the inner surface portion 53 a.

The flat surface portion 61b is formed over the entire length of the rib 61A in the vertical direction, similarly to the protruding portion 61A.

In the planar portion 61b, a plurality of groove portions 61c (concave portions) are formed at intervals in the vertical direction. Therefore, at the tip end portion of the rib 61A in the projecting direction, the flat surface portions 61b and the recessed portions 61c are formed alternately in the vertical direction on the-X direction side with respect to the ridge portions 61A. The flat surface portion 61b and the groove portion 61c form a concave-convex engaging portion E as a whole. Hereinafter, when the concave-convex engagement portion E of the rib 61A is clearly shown, the concave-convex engagement portion Ea is denoted.

The recessed portion 61c is a recessed portion in the concave-convex engaging portion E. The flat surface portions 61b are opposing convex portions in the concave-convex engaging portion E.

The shape of the recessed groove 61c is not particularly limited as long as it is a shape capable of engaging with an engagement portion in a clamping mechanism described later.

In the example shown in fig. 5, the groove portion 61c has a V shape that opens in the + Y direction when viewed in the lateral width direction. More specifically, as shown in fig. 6, the groove portion 61c includes a lower bent portion 61d, a lower engaging portion 61e, a groove bottom portion 61f, an upper engaging portion 61g, and an upper bent portion 61 h.

The lower bent portion 61d is curved in an arc shape with an outer side convex in the-Y direction from the upper end of the flat surface portion 61 b. In the example shown in fig. 6, the radius of curvature of the lower curved portion 61d is R1.

The lower engaging portion 61e is a flat surface portion extending in the-Y direction from the end of the lower bent portion 61d in the-Y direction. The end of the lower engaging portion 61e in the + Y direction is smoothly connected to the flat surface portion 61b by the lower bent portion 61 d.

The groove bottom portion 61f is an end surface in the-Y direction in the groove portion 61 c. The groove bottom portion 61f may be a curved surface curved in an arc shape, for example, or may be a plane having a depth direction as a normal direction. The distance from the planar portion 61b to the groove bottom portion 61f is d 1.

The upper engaging portion 61g is an inclined surface extending in an obliquely upward direction extending in the + Y direction as it goes from the upper end of the groove bottom portion 61f in the + Z direction. The inclination angle of the upper engaging portion 61g with respect to the lower engaging portion 61e is θ 1. The size of θ 1 is not particularly limited as long as it is an acute angle.

The upper bent portion 61h is bent in an arc shape with an outer side convex from the upper end of the upper engaging portion 61g toward the upper flat surface portion 61 b. In the example shown in fig. 6, the radius of curvature of the upper curved portion 61h is R2. In the present embodiment, R2 is preferably larger than R1.

In the present embodiment, the concave-convex engagement portions Ea in the ribs 61A are used to engage the ends of the 1 st case 56A and the 3 rd case 56C in the + X direction.

Therefore, the number and the arrangement interval of the recessed grooves 61C in the concave-convex engaging portion Ea are appropriately set according to the arrangement position required for the 1 st case 56A and the 3 rd case 56C. The number and arrangement intervals shown in fig. 5 and the like are merely examples.

In the example shown in fig. 5, the number of the groove portions 61c is 11. The respective groove portions 61c are formed at equal intervals in the up-down direction. Of these, the upper 5 are used to arrange the 1 st cartridge 56A. The lower 6 are used to arrange the 3 rd cartridge 56C.

The protruding height of the protruding portion 61a from the flat surface portion 61b (the amount of recess of the flat surface portion 61b from the tip of the protruding portion 61 a) is not particularly limited. For example, the protruding height of the protruding portion 61a may be an appropriate height at which the concave-convex engagement portion Ea is not easily visible.

When the rib 61A is viewed from the-X direction, the protruding portions 61A cover the flat surface portions 61b and the recessed portions 61c, and thus the concave-convex engagement portions Ea are hidden. This improves the appearance of the right refrigerating chamber door 11 Ab.

As shown in fig. 4A, a guide portion 64A and a step portion 53c are provided on a side surface S of the rib 61A on the-X direction side.

The rail portion 64A is a vertically elongated protrusion that protrudes in the-X direction from the side surface S and extends linearly.

As shown in fig. 5, the rail portion 64A is disposed on the inner surface portion 53a side of the concave-convex engagement portion Ea in the depth direction. The rail portion 64A has a1 st rail portion 64A and a2 nd rail portion 64b (slip-off prevention portion).

The 1 st rail portion 64a has a rectangular shape having a rear surface 64c on the + Y direction side, a front surface 64d on the-Y direction side, an upper surface 64e on the + Z direction side, and a lower surface 64f on the-Z direction side, as viewed from the + X direction. The configuration of the inner side of the 1 st rail portion 64a is not particularly limited. In the present embodiment, the 1 st rail portion 64a is a cylindrical body along the outer shape described above. A plurality of ribs 64g connecting the inner walls in the depth direction are provided inside the 1 st rail portion 64 a.

The upper surface 64e is located above the uppermost position of the 1 st case 56A described later. In the present embodiment, the recess portion 61c is located above the uppermost recess portion in the concave-convex engagement portion Ea.

Further, the upper surface 64e is disposed to be spaced downward from the side surface of the rib 61F in the-Z direction. A gap 64h (opening) is formed between the rib 61F and the upper surface 64e in the vertical direction. The size of the gap 64h is not particularly limited as long as it is sufficient for attachment and detachment of the 1 st cartridge 56A described later.

The lower surface 64f is located below a lowest arrangeable position of the 3 rd case 56C described later. In the present embodiment, the recess portion 61c is located below the lowermost recess portion in the concave-convex engagement portion Ea.

The 2 nd rail portion 64b is separated from the lower surface 64f of the 1 st rail portion 64a in the-Z direction, and is disposed in series with the 1 st rail portion 64 a. The 2 nd rail portion 64b has a rectangular shape having a rear surface 64j on the + Y direction side, a front surface 64k on the-Y direction side, an upper surface 64m on the + Z direction side, and a lower surface 64n on the-Z direction side, as viewed from the + X direction.

The depth direction position of the rear surface 64j is substantially the same as the rear surface 64c, and the depth direction position of the front surface 64k is the same as the front surface 64 d.

The lower surface 64n forms the lowermost surface of the rail portion 64A. In the example shown in fig. 5, the lower surface 64n in the vertical direction is substantially the same as the position of the lower end of the flat surface portion 61 b.

The upper surface 64m is separated from the lower surface 64f in the up-down direction. A gap 64i (opening portion) is formed between the upper surface 64m and the rear surface 64 c. The size of the gap 64i is a size that allows the locking projection 57 of the gripping mechanism 60 described later to pass through in the depth direction.

The position of the gap 64i in the vertical direction is set according to the position at which the 3 rd cartridge 56C described later is attached and detached. In the present embodiment, the 3 rd container 56C is configured to be attachable and detachable below the arrangement position thereof, and therefore the gap 64i is located near the lower end of the rail portion 64A. Therefore, in the example shown in fig. 5, the 2 nd rail portion 64b is far shorter than the 1 st rail portion 64 a. However, the length of the 2 nd rail portion 64b in the vertical direction is preferably such a length that the locking projection 57 of the gripping mechanism 60 described later does not go over the 2 nd rail portion 64b when the 3 rd container 56C described later falls.

As shown in fig. 4A, the step portion 53c protrudes in the-X direction from the side surface S of the rail portion 64A between the rail portion 64A and the inner surface portion 53 a. The protruding height of the step portion 53c is not particularly limited, but is preferably not more than the protruding height of the rail portion 64A. In the example shown in fig. 4A, the step portion 53c protrudes to the same position as the rail portion 64A.

As shown in fig. 5, the step portion 53c is separated from the front surface 64d in the-Y direction and extends parallel to the front surface 64 d. The lower end of the step portion 53c extends to a position opposing the gap 64i in the depth direction. The upper end of the step portion 53c is connected to the lower surface of the rib 61F.

A1 st stopper 53d (stopper) is provided between the front surface 64d of the rail portion 64A and the step portion 53c, and the 1 st stopper 53d protrudes in the-X direction from the side surface S of the rib 61A across the gap Ga between the front surface 64d of the rail portion 64A and the step portion 53 c.

The 1 st stopper 53d is provided to limit a lowering position of the 1 st container 56A described later. The position of the 1 st stopper 53d in the vertical direction defines the movable lowermost position of the 1 st cassette 56A. The lowest position of the 1 st container 56A can be set as appropriate as needed. However, the 1 st stopper 53d defines the movable uppermost position of the 3 rd container 56C described later. The 3 rd box 56C described later is a container disposed below the 1 st box 56A.

In the example shown in fig. 5, the 1 st stopper 53d is provided at a substantially central portion of the front surface 64d in the up-down direction. Therefore, the 1 st case 56A can move in the vertical direction within the upper half of the 1 st rail portion 64a, and the 3 rd case 56C can move in the vertical direction within the lower half of the 2 nd rail portion 64 b.

For example, the position of the 1 st stopper 53d is preferably such that: when the 3 rd cassette 56C described later is moved to the uppermost position, the lower surface of the 1 st cassette 56A at the lowermost descending position (hereinafter, referred to as lowermost position) of the 1 st cassette 56A described later is higher than the upper end of the 3 rd cassette 56C. In this case, even if the 1 st case 56A is lowered to the lowermost position, collision of the 1 st case 56A with the 3 rd case 56C can be prevented.

For example, the position of the 1 st stopper 53d is more preferably such that: at the lowest position of the 1 st case 56A described later, the lower surface of the 1 st case 56A is higher than the upper end of the 3 rd case 56C by a height obtained by adding a predetermined height to the height of the upper end of the 3 rd case 56C. Here, the height added to the height of the upper end may be a height suitable for allowing a specific contained object such as a can container, a bottle container, a carton-packed beverage, an egg, etc. contained in the 3 rd box 56C to protrude from the upper end of the 3 rd box 56C.

In this case, even if the 1 st case 56A is lowered to the lowermost position, the specific stored item stored in the 3 rd case 56C can be prevented from colliding with the 1 st case 56A.

However, in this case, the position of the 3 rd container 56C may be the uppermost position in the movement range, or may be a specific position other than the uppermost position in the movement range.

For example, the position of the 1 st stopper 53d may be as follows: when the 3 rd case 56C is at the uppermost position, the upper end of the 3 rd case 56C does not collide with the 1 st case 56A at the lowermost position, and when the 3 rd case 56C is at the lowermost position, the specific contents do not collide with the 1 st case 56A at the lowermost position.

A2 nd stopper 53e (stopper) extending toward the boundary between the inner surface portions 53a and 53b and protruding from the side surface S of the rib 61A in the-X direction is provided on the front surface 64k of the 2 nd rail portion 64 b.

The 2 nd stopper 53e is provided to limit the lowering position of the 3 rd container 56C described later. The length of the 2 nd stopper 53e in the depth direction is not particularly limited as long as the lowering position of the 3 rd container 56C described later can be restricted. In the example shown in fig. 5, the length of the 2 nd stopper 53e in the depth direction is substantially equal to the gap Ga.

The position of the 2 nd stopper 53e in the vertical direction defines the movable lowermost position of the 3 rd cartridge 56C. The lowermost position of the 3 rd container 56C can be set as appropriate as needed. In the example shown in fig. 5, the 2 nd stopper 53e extends in the-Y direction from the position of the intersection of the front surface 64k and the lower surface 64 n.

For example, the position of the 2 nd stopper 53e is preferably such that: the lower surface of the 3 rd case 56C at the lowest position of the 3 rd case 56C described later is higher than the upper end of the case 59 described later. In this case, even if the 3 rd case 56C is lowered to the lowermost position, collision of the 3 rd case 56C with the case 59 can be prevented.

For example, the position of the 2 nd stopper 53e is more preferably such that: at the lowest position of the 3 rd case 56C described later, the lower surface of the 3 rd case 56C is higher than the upper end of the case 59 described later by a height obtained by adding a predetermined height to the height of the upper end of the case 59. Here, the height added to the height of the upper end may be a height at which a specific contained material such as a can container, a bottle container, a carton-packed beverage, or the like, which is suitable for being contained in the cartridge case 59, is projected from the upper end of the 3 rd cartridge case 56C.

In this case, even if the 3 rd case 56C is lowered to the lowermost position, the specific stored object stored in the case 59 can be prevented from colliding with the 3 rd case 56C.

As shown in fig. 4A, the rib 61D extends from the lower end of the rib 61A to the end in the + X direction in the rib 61G. The inner side surface (the side in the (-X direction) of the rib 61D is located at a position closer to the + X direction than the inner side surface S of the rib 61A. Therefore, the thickness of the rib 61D is thinner than that of the rib 61A.

The locking guide projection 53f and the locking projection 65 project in the-X direction from the inner side surface of the rib 61D. The shapes of the locking guide projection 53f and the locking projection 65 are not particularly limited as long as the box 59 can be detachably locked.

The rib 61G in the present embodiment has: a1 st plate-shaped portion 61Ga extending in the + Y direction from the lower end of the inner surface portion 53b, and a2 nd plate-shaped portion 61Gb extending in the + Y direction from the 1 st plate-shaped portion 61 Ga. However, the 1 st plate-like portion 61Ga and the 2 nd plate-like portion 61Gb have upper surfaces inclined in the-Z direction as going to the + Y direction.

The locking guide projection 53f extends in the + Z direction from the upper surface of the end edge of the 1 st plate-like portion 61Ga in the + X direction as a whole in the depth direction.

The locking protrusion 65 is located above the 2 nd plate-shaped portion 61Gb, is separated from the end of the locking guide protrusion 53f in the + Y direction, and extends parallel to the locking guide protrusion 53 f.

The respective distal end surfaces of the ribs 61D, 61G in the projecting direction are formed at the same positions as the distal ends of the protruding strip portions 61A of the rib 61A.

As shown in fig. 4B, an illumination portion 62 is provided on the side surface of the rib 61A in the + X direction, and when the right refrigerating compartment door 11Ab is opened, the illumination portion 62 illuminates the inside of the refrigerating compartment 27A.

For example, the illumination unit 62 includes a light diffusion plate provided on the side surface of the rib 61A in the + X direction and a light source provided inside the rib 61A.

As shown in fig. 4B and 7, the ribs 61C, 61E and the rail portion 64C have shapes and arrangements that are plane-symmetrical with respect to the ribs 61A, 61D and the rail portion 64A, respectively, with respect to a plane between the ribs 61A, 61C with the lateral width direction as a normal direction. However, the illumination portion 62 is not provided in the rib 61C. The rib 61C is continuous with the side surface thereof at a portion corresponding to the illumination portion 62, and is filled with a foamed heat insulating material, not shown, in the same manner.

Therefore, the structures of the ribs 61C, 61E and the rail portion 64C are easily understood as long as the + X direction and the-X direction are interchanged in the above description, and thus detailed description is omitted. For example, the rib 61C has a concave-convex engagement portion E similar to the rib 61A on the + X direction side of the ridge portion 61A. Hereinafter, when the concave-convex engagement portion E of the rib 61C is specifically and clearly shown, the concave-convex engagement portion Ec is denoted. For example, a gap Gc similar to the gap Ga is formed between the stepped portion 53C and the rail portion 64C.

The same applies to the stepped portion 53C of the rib 61C, the 1 st stopper 53d and the 2 nd stopper 53E, and the locking protrusion 65 and the locking guide protrusion 53f of the rib 61E.

As shown in fig. 4A and 4B, the rib 61B protrudes in the + Y direction from the inner surface portion 53a between the ribs 61A and 61C. The rib 61B extends from the rib 61F to a substantially central portion of the inner surface portion 53a in the up-down direction. For example, in the example shown in fig. 7, the rib 61B extends to the center of the concave-convex engagement portion Ec in the rib 61C (the position of the 6 th groove portion 61C from the upper side) when viewed from the-X direction.

The rib 61B has a side surface Sm (see fig. 4A) on the-X direction side and a side surface Sp (see fig. 4B) on the + X direction side. The side surface Sm faces the side surface S of the rib 61C in the lateral width direction. The side surfaces Sp face the side surfaces S of the ribs 61A in the lateral width direction.

At the tip end of the rib 61B in the protruding direction, a concave-convex engagement portion E is formed over the range of the length of the rib 61B in the vertical direction.

The flat surface portion 61B in the rib 61B forms a front end surface in the protruding direction of the rib 61B. The groove portion 61c of the rib 61B is formed in the same manner as the groove portion 61c of the upper half portion of the concave-convex engagement portion Ea. For example, in the example shown in fig. 7, the groove portions 61c in the ribs 61B have the same shape and arrangement as the upper 5 of the concave-convex engagement portions Ea.

In this way, the number of concave-convex engagement portions E in the rib 61B is smaller than the number of concave-convex engagement portions Ea in the recessed groove 61 c. Hereinafter, when the concave-convex engagement portion E of the rib 61B is specifically shown, the concave-convex engagement portion Eb is denoted.

The thickness of the rib 61B in the lateral width direction is at least 2 times the width of the concave-convex engagement portion Ea. The groove portion 61c of the concave-convex engagement portion Ec may not penetrate through the thickness direction (lateral width direction) of the rib 61B, but a penetrating form is adopted in the present embodiment.

When the groove portion 61c is not penetrated in the thickness direction of the rib 61B, the groove portion 61c is formed from the side surfaces Sm, Sp of the rib 61B toward the inner side of the rib 61B.

As shown in fig. 4A, the side surface Sm is provided with a rail portion 64Bc and a step portion 53 g.

The rail portion 64Bc is a projection projecting in the + X direction, like the 1 st rail portion 64a of the rib 61A, except for the point of being provided on the side surface Sm and the point of being short in the vertical direction length.

That is, the rail portion 64Bc includes: the upper surface 64e, which is similar to the 1 st rail portion 64a, and the rear surface 64c and the front surface 64d, which are shorter than the 1 st rail portion 64a in the vertical direction, include a lower surface 64p instead of the lower surface 64 f.

The lower surface 64p is formed at the same position as the upper end surface of the 1 st stopper 53d when viewed from the-Y direction.

The stepped portion 53g is formed in the same manner as the stepped portion 53c except for the point of being provided on the side surface Sm and the point of being formed in the range of the length of the rib 61B in the vertical direction. With this configuration, a gap Gbc similar to the gap Ga is formed between the rail portion 64Bc and the step portion 53 g. The gap Gba may be provided with or without the 1 st stopper similar to the 1 st stopper 53d in the gap Ga. In the example shown in fig. 4A, the 1 st stopper 53d is not provided at the gap Gba.

As shown in fig. 4B and 7, the side surface Sp is provided with a rail portion 64Ba and a step portion 53 g. The rail portion 64Ba and the step portion 53g have a shape and an arrangement which are plane-symmetrical to the rail portion 64Bc and the step portion 53g in the side surface Sm with respect to a plane having the lateral width direction as a normal direction between the side surfaces Sp and Sm. Therefore, in the above description, for example, the + X direction and the-X direction are interchanged to facilitate understanding, and therefore, detailed description is omitted. With this configuration, a gap Gba similar to the gap Ga is formed between the rail portion 64Ba and the step portion 53 g. The gap Gba may be provided with or without the 1 st stopper similar to the 1 st stopper 53d in the gap Ga. In the examples shown in fig. 4B and 7, the 1 st stopper 53d is not provided in the gap Gba.

As described above, in the rear surface member 53, the rib 61B is the 2 nd wall portion facing the rib 61A (the 1 st wall portion) in the lateral width direction (the 2 nd direction) intersecting the projecting direction (+ Y direction, the 1 st direction) of the rib 61A. Concave-convex engaging portions E (concave-convex engaging portions Ea, Eb) are provided at the 1 st direction distal end portions of the ribs 61A, 61B, respectively. The ribs 61A and 61B are provided with rail portions 64 (rail portions 64A and 64Ba) that protrude from the side surfaces S, Sp facing each other and extend in the vertical direction.

Similarly, the ribs 61C and 61B correspond to the 1 st wall part and the 2 nd wall part, respectively, and have concave-convex engaging parts E (concave-convex engaging parts Ec and Eb) at the 1 st direction distal end portions thereof. Further, the ribs 61C and 61B are provided with rail portions 64 (rail portions 64C and 64Bc) that protrude from the side surfaces S, Sm facing each other and extend in the vertical direction.

Similarly, the ribs 61A and 61C correspond to the 1 st wall part and the 2 nd wall part, respectively, and have concave-convex engaging parts E (concave-convex engaging parts Ea and Ec) at the 1 st direction distal end parts thereof. Further, the ribs 61A and 61C are provided with rail portions 64 ( rail portions 64A and 64C) that protrude from the side surfaces S, S that face each other and extend in the vertical direction.

In addition, the correspondence between the 1 st wall portion and the 2 nd wall portion of the wall portions facing each other may be reversed.

The detailed structure of the plurality of cartridges 56 will be described next.

As shown in fig. 3, each box 56 can move vertically between the 1 st wall part and the 2 nd wall part along the rail part. Each of the cases 56 includes a case main body 56a, and the case main body 56a has a length (width) in the lateral direction that can enter a gap between the 1 st wall portion and the 2 nd wall portion disposed in each case 56.

When the cartridge main bodies 56A of the 1 st cartridge 56A, the 2 nd cartridge 56B, and the 3 rd cartridge 56C are distinguished, the cartridge main bodies 56aA, 56aB, and 56aC may be referred to as "cartridge main bodies".

The 1 st case 56A is disposed between the ribs 61A, 61B. The 2 nd case 56B is disposed between the ribs 61C, 61B. The 3 rd case 56C is disposed between the ribs 61A, 61B.

The structure common to the cartridges 56 will be described with reference to the 1 st cartridge 56A as an example.

Hereinafter, unless otherwise specified, the positional relationship of each part will be described based on the direction of fixing to the refrigerator 1. However, the 1 st box 56A is attached and detached with the right refrigerating chamber door 11Ab opened. The opening angle of the right refrigerating chamber door 11Ab is arbitrary within the opening limit.

Therefore, the left, right, front, and rear as viewed from the user when the user faces the inner surface side of the right refrigerating chamber door 11Ab with the right refrigerating chamber door 11Ab open (hereinafter referred to as a normal pair) are different from those defined in the present specification. Hereinafter, the positional relationship at the time of alignment may be supplemented as necessary.

Fig. 8 is a perspective view showing an example of the door container in the embodiment. Fig. 9 is an exploded perspective view of the door container shown in fig. 8. Fig. 10 is a sectional view of the door container shown in fig. 8, taken along the line F10-F10.

As shown in fig. 8, the 1 st cartridge 56A has a cartridge main body 56aA and a chucking mechanism 60.

The case body 56aA is formed in a bowl shape with an open upper side. The cartridge body 56aA has a substantially cubic shape. Here, the substantially cubic shape means a shape similar to a cube, in which any one of corners, ridge lines, and faces of the cube is given various shapes such as rounded corners, curved shapes, bent shapes, stepped shapes, and uneven shapes, in addition to the shape of the cube. The cartridge body 56aA may have a through hole, a cutout, or the like penetrating in the thickness direction. However, the following description will be given taking as an example a case where the 1 st case 56A does not have a through hole, a cutout, or the like penetrating in the thickness direction.

The case body 56aA has a bottom 56f, a1 st wall portion 56b, a2 nd wall portion 56c, a1 st side wall portion 56d, and a2 nd side wall portion 56 e.

The bottom portion 56f has a substantially rectangular shape having a peripheral edge extending in the lateral width direction and the depth direction in a plan view (in the Z direction).

The 1 st wall portion 56b extends in the + Z direction from the peripheral edge of the bottom portion 56f in the + Y direction.

The 2 nd wall portion 56c extends in the + Z direction from the peripheral edge in the-Y direction in the bottom portion 56 f. The 2 nd wall portion 56c is a wall portion that faces the inner surface portion 53a when disposed inside the refrigerator 1. For example, the 2 nd wall portion 56c is formed of a flat surface substantially parallel to the inner surface portion 53 a.

The 1 st side wall portion 56d extends in the + Z direction from the peripheral edge of the bottom portion 56f in the + X direction. The 1 st side wall portion 56d is on the left hand side when directly facing as viewed from the user.

The 2 nd side wall portion 56e extends in the + Z direction from the peripheral edge in the-X direction in the bottom portion 56 f. The 2 nd side wall portion 56e is located on the right hand side when viewed from the user while facing.

The type of the contents in the 1 st case 56A is not particularly limited.

The chucking mechanism 60 includes a chucking mechanism 60R provided on the 2 nd side wall portion 56e and a chucking mechanism 60L provided on the 1 st side wall portion 56 d.

The clamping mechanism 60R has a locking projection 57R and a locking portion 58R. The clamping mechanism 60L includes a locking projection 57L and a locking portion 58L.

The lock portions 58R, 58L are located on the right-hand side and the left-hand side, respectively, when facing each other, as viewed from the user.

Hereinafter, the suffix R, L may be appropriately omitted without causing misunderstanding. For example, when one of the locking projections 57R and 57L is shown, it may be simply referred to as the locking projection 57, or both of the locking projections 57R and 57L may be collectively referred to as the locking projections 57.

The locking projection 57R projects from the 2 nd side wall portion 56e in the-X direction at the end of the 2 nd side wall portion 56e in the-Y direction. In the example shown in fig. 8, the shape of the locking projection 57R as a whole is long in the vertical direction when viewed from the + X direction. The upper end of the locking projection 57R is located near the upper end of the 2 nd side wall portion 56 e. The lower end of the locking projection 57R is located at a substantially central portion in the vertical direction of the 2 nd side wall portion 56 e.

The outer surface of the locking projection 57R in the-Y direction is formed by a flat surface portion 57d, and the flat surface portion 57d is formed by a flat surface extending in the vertical direction and facing the-Y direction. In the example shown in fig. 8, the flat portion 57d is parallel to the 2 nd wall portion 56 c. The distance in the depth direction from the flat surface portion 57d to the outer surface of the 2 nd wall portion 56c is shorter than the distance in the depth direction from the inner surface portion 53a to the step portions 53c, 53 g.

The outer surface of the locking projection 57R in the + Y direction includes an upper convex portion 57a and a lower convex portion 57b protruding in the-Y direction from both end portions in the vertical direction. A concave portion 57c that is concave in the-Y direction is formed between the upper convex portion 57a and the lower convex portion 57 b.

the-Y direction distal ends of the upper convex portion 57a and the lower convex portion 57b are located on the same plane parallel to the plane portion 57 d.

The locking projection 57R has a width in the depth direction smaller than the gap between the rail portion 64Ba and the stepped portion 53 g.

The locking projection 57L has a shape and an arrangement that are plane-symmetrical to the locking projection 57R with respect to a plane having a normal direction in the lateral width direction between the 2 nd side wall portion 56e and the 1 st side wall portion 56 d. Therefore, the locking projection 57L has a flat surface portion 57d, an upper convex portion 57a, a lower convex portion 57b, and a concave portion 57c similar to the locking projection 57R, except that it projects from the 1 st side wall portion 56d in the-X direction.

The locking projection 57L has a width in the depth direction smaller than the gap between the rail portion 64A and the step portion 53 c.

Regarding the dimension of the 1 st case 56A in the lateral width direction, the distance from the outer surface of the 1 st side wall portion 56d to the outer surface of the 2 nd side wall portion 56e is shorter than the distance between the front end surfaces of the rail portions 64A, 64Ba in the respective projecting directions. Further, the distance between the distal end surfaces of the locking projections 57L, 57R in the protruding direction is shorter than the gap between the side surface S of the rib 61A and the side surface Sp of the rib 61B.

Therefore, the 1 st case 56A can move in the vertical direction between the side surface S of the rib 61A and the side surface Sp of the rib 61B. At this time, the locking projection 57L can move in the vertical direction through the gap between the rail portion 64A and the stepped portion 53 g. The locking projection 57R can move in the vertical direction through the gap between the rail portion 64Ba and the stepped portion 53 g.

The length of the locking projection 57L in the vertical direction in the 1 st case 56A is shorter than the vertical gap of the gap 64 h. Therefore, the locking projection 57L in the 1 st case 56A can move in the depth direction through the gap 64 h.

The length of the locking projection 57R in the vertical direction in the 2 nd container 56B described later is also the same as the locking projection 57L in the 1 st container 56A.

The lock portion 58R is provided at an end portion in the + Y direction in the 2 nd side wall portion 56 e.

As shown in fig. 9, the lock portion 58R includes a holding portion 58a, a slide member 71 (an engaging portion), an elastic member 72, a locking holder 73, and a cover 70.

The locking portion 58L has a shape and an arrangement that are plane-symmetrical to the locking portion 58R with respect to a plane having a normal direction in the lateral width direction between the 2 nd side wall portion 56e and the 1 st side wall portion 56 d. Therefore, the shapes and the arrangements of the holding portion 58a of the lock portion 58L, the slide member 71, the elastic member 72, the locking holder 73, and the cover 70 can be easily understood if the + X direction and the-X direction are interchanged in the description of the structure of the lock portion 58R. In particular, the cross-sectional shapes of the locking portions 58R and 58L are common to each other, the cross-sectional shapes being formed by planes whose normal directions are the lateral width directions.

Hereinafter, the structure of the lock portion 58R will be described without specific reference. However, as for the parts not visible in the drawings, the corresponding parts of the lock portion 58L may be referred to in the drawings.

The holding portion 58a includes a1 st guide plate 58b, a2 nd guide plate 58c, and a locking plate 58 d.

The 1 st guide plate 58b is a flat plate that protrudes in the-X direction from the vicinity of the upper end of the 2 nd side wall portion 56e and extends in a depth direction in an elongated manner. The 1 st guide plate 58b has a constant width in the lateral width direction from the intermediate portion to the-Y direction side in the depth direction, and the width in the lateral width direction from the intermediate portion to the + Y direction side gradually decreases toward the + Y direction in the plan view. The length of the 1 st guide plate 58b in the depth direction is not particularly limited as long as it is apart from the locking projection 57R, and is about half the length of the 2 nd side wall portion 56e in the depth direction in the example shown in fig. 9.

The 2 nd guide plate 58c is a flat plate that is below the 1 st guide plate 58b and protrudes in the-X direction at a position apart from the 1 st guide plate 58 b. The 2 nd guide plate 58c has the same outer shape as the 1 st guide plate 58b in a plan view. The 2 nd guide plate 58c is disposed at a position overlapping with the 1 st guide plate 58b when viewed from the-Z direction.

The distance in the vertical direction between the 2 nd guide plate 58c and the 1 st guide plate 58b is a size that can slidably hold a slide member 71, which will be described later, in the depth direction.

A C-shaped cutout 58f in plan view, through which an operating lever 71B of a slide member 71 described later can be inserted in the lateral width direction and the depth direction, is formed in a portion of the 2 nd guide plate 58C closer to the-Y direction.

At least 1 locking hole 58e penetrating in the plate thickness direction is formed at the base end portion in the projection direction (-X direction) of the 1 st guide plate 58b and the 2 nd guide plate 58c, respectively. The locking holes 58e are used to lock a cover 70 described later.

For example, in the example shown in fig. 9, 2 locking holes 58e are formed in the 1 st guide plate 58b so as to be separated in the depth direction. Although not shown in fig. 9, in the 2 nd guide plate 58c, a locking hole 58e is formed at a position facing the locking hole 58e on the + Y direction side in the 1 st guide plate 58 b.

The locking plate 58d is a flat plate whose depth direction is a normal direction. The locking plate 58d protrudes in the-X direction from a position closer to the + Y direction than the notch 58f between the 1 st guide plate 58b and the 2 nd guide plate 58 c. The locking plate 58d connects the 1 st guide plate 58b and the 2 nd guide plate 58c to each other in the up-down direction.

A locking groove 58g for locking a locking holder 73 to be described later in the vertical direction and the + X direction is formed at a front end portion in the protruding direction of the locking plate 58 d.

The slide member 71 has a slider 71A and an operating lever 71B.

The slider 71A is accommodated in the gap between the 1 st guide plate 58b and the 2 nd guide plate 58c, and is slidable in the depth direction. A projecting engagement portion 71A engageable with the recessed groove portion 61c in the vertical direction is provided at a front end portion of the slider 71A in the-Y direction.

The operating lever 71B is a rod-shaped member extending in the-Z direction from the middle portion of the lower surface of the slider 71A in the depth direction. The operating lever 71B is inserted into the cutout 58f and protrudes below the 2 nd guide plate 58 c.

The detailed configuration of the slide member 71 is left to be described later.

The elastic member 72 is a member that biases the slider 71A in the-Y direction. The elastic member 72 is not particularly limited as long as it can bias the slider 71A in the-Y direction. For example, as the elastic member 72, an appropriate elastic member, a spring, or the like capable of biasing in the-Y direction is used. For example, the elastic member 72 can generate an elastic restoring force in the-Y direction when compressed in the + Y direction. In the example shown in fig. 9, as the elastic member 72, a compression coil spring which is one kind of spring is used.

The locking holder 73 holds a proximal end portion 72b, which is an end portion of the elastic member 72 in the + Y direction.

The cross-sectional structure of the locking holder 73 will be described based on the cross-sectional view of the lock portion 58L shown in fig. 10.

The locking holder 73 has a1 st locking plate 73b, a2 nd locking plate 73c, a locking shaft 73d, and a cylindrical portion 73 a.

The 1 st locking plate 73b and the 2 nd locking plate 73c are flat plates disposed in parallel with each other with a gap into which the locking plate 58d can be inserted. The 1 st locking plate 73b and the 2 nd locking plate 73c are coupled to each other by a locking shaft 73d provided at the center portion thereof.

The locking shaft 73d has an outer diameter slightly smaller than the groove width of the locking groove 58 g.

Thus, the locking holder 73 is locked to the locking plate 58d in a state where the locking shaft 73d is inserted into the locking groove 58g and the locking plate 58d is sandwiched between the 1 st locking plate 73b and the 2 nd locking plate 73 c.

The cylindrical portion 73a accommodates the base end portion 72b of the elastic member 72 therein. The shape of the cylindrical portion 73a can be an appropriate shape corresponding to the shape of the elastic member 72 to be housed. In the example shown in fig. 9, the elastic member 72 is formed of a compression coil spring having a columnar outer shape, and accordingly, the cylindrical portion 73a is cylindrical having a circular hole portion along the outer shape of the elastic member 72.

The proximal end 72b of the elastic member 72 is fixed to a predetermined position inside the tube 73 a.

As shown in the perspective view of the lock portion 58L and the exploded perspective view of the lock portion 58R in fig. 9, the cover 70 covers the slider 71A, the elastic member 72, the locking holder 73, and the holding portion 58a from the outside.

The cover 70 has: an upper plate portion 70a covering the 1 st guide plate 58b from above, a lower plate portion 70b covering the 2 nd guide plate 58c from below, and a side plate portion 70c vertically connecting the upper plate portion 70a and the lower plate portion 70 b.

The side plate portion 70c is formed in a curved plate shape that covers the respective front ends in the projecting direction and the end portion in the + Y direction of the 1 st guide plate 58b and the 2 nd guide plate 58c from the outside. Specifically, the side plate portion 70c includes a flat plate portion 70d covering the-Y direction side of the 1 st guide plate 58b and the 2 nd guide plate 58c, and a convex curved portion 70e covering the same + Y direction side.

Therefore, although the locking portions 58 project outward in the lateral width direction from both lateral width direction side surfaces of the 1 st case 56A, the projecting amounts gradually decrease toward the + Y direction end portions.

The convex bending portion 70e is shaped so that the locking portion 58R in the 2 nd and 3 rd cases 56B and 56C does not interfere with the left refrigerating compartment door 11Aa when the right refrigerating compartment door 11Ab is opened and closed. For example, the convex curved portion 70e is formed in a curved shape converging on the inner side (hinge 30 side) of the rotation locus drawn by the left member 51c centering on the hinge 30.

In fig. 9, as shown in the cover 70 of the locking portion 58L, a cutout portion 70f is formed in the lower plate portion 70b at a position overlapping the cutout portion 58f from below.

The cutout 70f is formed in a shape that allows the operation rod 71B to be inserted in the lateral width direction and the depth direction.

The cover 70 has a substantially rectangular opening surrounded by the upper plate 70a, the side plate 70c, and the lower plate 70b at the end in the-Y direction. The opening has a size allowing the slider 71A to move forward and backward in the depth direction.

An engaging projection 70g that engages with the engaging hole 58e in the 2 nd guide plate 58c is formed on the upper surface of the lower plate portion 70 b. Although not shown in fig. 9, an engaging projection 70g is also provided on the lower surface of the upper plate portion 70a at a portion that engages with each of the locking holes 58e of the 1 st guide plate 58 b.

The cover 70 is fixed to the holding portion 58a in a state where the holding portion 58a is covered from the outside in the vertical direction and the outside in the lateral width direction by the engagement of the engagement projections 70g with the engagement holes 58 e.

As shown in fig. 8, the amount of projection of the lock portion 58L from the 1 st side wall portion 56d in the + X direction and the amount of projection of the lock portion 58R from the 2 nd side wall portion 56e in the-X direction when the cover 70 is assembled are W. The size of W is larger than both the width of the flat surface portion 61B of the rib 61A and half of the width of the flat surface portion 61B of the rib 61B. Further, the distance between the outer surfaces of the side plate portions 70c is shorter than the distance from the inner surface of the ridge portion 61a to the center portion of the flat surface portion 61B of the rib 61B.

Therefore, the 1 st box 56A can be accommodated in the range from the inner surface of the ridge portion 61a to the center portion of the flat surface portion 61B of the rib 61B in the lateral width direction.

In this way, each locking portion 58 protrudes in a range overlapping with the concave-convex engagement portion E on the + Y direction side of the concave-convex engagement portion E to be engaged. This is arranged on the front side of the ribs 61A and 61B when facing, and therefore, the operator can easily see the rib. Further, since each locking portion 58 and the concave-convex engagement portion E to be engaged are in a positional relationship overlapping in the depth direction, each locking portion 58 can be compactly housed without narrowing the width of the case 56 in the lateral width direction. Since each locking portion 58 does not protrude outward of the rib 61A in the lateral width direction, the right refrigerating compartment door 11Ab can be smoothly opened and closed.

Next, a detailed configuration of the slide member 71 and an internal configuration of the lock portion 58 will be described based on a cross-sectional view of the lock portion 58L shown in fig. 10. Fig. 10 shows the position of the slide member 71 in the locked state in which the protruding engagement portion 71a is engaged with the recessed portion 61 c.

The slider 71A has an upper sliding portion 71g and a lower sliding portion 71h extending in parallel to the lower surface of the 1 st guide plate 58b and the upper surface of the 2 nd guide plate 58c at the upper end and the lower end, respectively. The distance in the vertical direction between the upper slide portion 71g and the lower slide portion 71h is slightly smaller than the distance between the 1 st guide plate 58b and the 2 nd guide plate 58 c. Therefore, the slider 71A can slide in the depth direction along at least one of the lower surface of the 1 st guide plate 58b and the upper surface of the 2 nd guide plate 58 c.

The lengths of the upper sliding portion 71g and the lower sliding portion 71h in the depth direction are substantially equal to the lengths from the locking plate 58d to the respective ends of the 1 st guide plate 58b and the 2 nd guide plate 58c in the-Y direction.

The front end surfaces in the-Y direction of the upper sliding portion 71g and the lower sliding portion 71h are located on the same plane with the depth direction as the normal direction.

The front end surface of the upper slide portion 71g constitutes an upper locking portion 71e that locks with the flat surface portion 61b from the-Y direction in the locked state.

The front end surface of the lower slide portion 71h constitutes a lower locking portion 71f that locks with the flat surface portion 61b from the-Y direction in the locked state.

In the present embodiment, the convex engagement portion 71a is an engagement portion that engages with the concave-convex engagement portion E in the vertical direction, and the upper locking portion 71E and the lower locking portion 71f are engagement portions that engage with the concave-convex engagement portion E in the-Y direction.

The projecting engagement portion 71a projects in the-Y direction from the upper locking portion 71e and the lower locking portion 71 f. In the example shown in fig. 10, the convex engaging portion 71A protrudes from the center portion in the height direction of the slider 71A.

The shape of the protruding engagement portion 71a is not particularly limited as long as it can be engaged with at least one of the lower engagement portion 61e and the upper slide portion 71g of the groove portion 61c in the vertical direction.

In the present embodiment, the groove portion 61c has a V-shape that opens in the + Y direction when viewed in the lateral width direction, and correspondingly, the convex engagement portion 71a has a V-shape that narrows in the-Y direction when viewed in the lateral width direction.

For example, the convex engagement portion 71a includes a lower engagement portion 71b, a distal end surface 71d, and an upper engagement portion 71 c.

The lower engaging portion 71b is a flat surface portion extending in the horizontal direction.

The distal end surface 71d is curved in the + Z direction from the end of the lower engagement portion 71b in the-Y direction. The distance between the upper and lower locking portions 71e and 71f and the distal end face 71d (the amount of projection of the projecting engagement portion 71 a) is d 2. In the present embodiment, the size of d2 is smaller than the depth d1 of the groove portion 61 c.

The upper engaging portion 71c is an inclined surface extending in an obliquely upward direction toward the + Y direction from the upper end portion of the front end surface 71d toward the + Z direction. The inclination angle of the upper engagement portion 71c with respect to the lower engagement portion 71b is θ 2. The size of θ 2 is not particularly limited, as long as it is an acute angle. θ 2 is preferably about the same as θ 1.

A hole 71i that opens in the + Y direction is formed in the center of the slider 71A on the opposite side of the convex engagement portion 71A (the back side of the convex engagement portion 71A).

Inside the slider 71A, the + Y direction side of the hole 71i with respect to the opening is a space sandwiched between the upper sliding portion 71g and the lower sliding portion 71 h. The space has a size in which the cylindrical portion 73a of the locking holder 73 can relatively advance and retreat in the depth direction.

The hole 71i has a size capable of accommodating the elastic member 72 therein. In the present embodiment, the circular hole has an inner diameter slightly larger than the outer diameter of the elastic member 72. The hole 71i extends from the back side of the convex engagement portion 71A to the center of the slider 71A in the depth direction.

In the present embodiment, the outer diameter of the cylindrical portion 73a is larger than the inner diameter of the hole 71i, so that the cylindrical portion 73a cannot be inserted into the hole 71 i. Therefore, the sum of the depth of the hole 71i and the depth of the tube 73a defines a minimum length that can compress the elastic member 72. Therefore, when the elastic member 72 needs to be compressed to the length L0, the sum of the depth of the hole 71i and the depth of the tube 73a needs to be L1 smaller than L0. The depth of the hole 71i and the depth of the tube 73a are preferably about half of L1.

In the example shown in fig. 10, the depth of the hole 71i and the depth of the cylinder 73a are about one third to about two fifths of the length of the elastic member 72 in the locked state, respectively. Accordingly, when the operation lever 71B is pulled in the + Y direction and the elastic member 72 is most compressed, the elastic member 72 is substantially covered by the hole portion 71i and the tube portion 73 a.

The operating lever 71B has a coupling shaft 71k and a lever main body 71 j.

The coupling shaft 71k extends in the-Z direction from a substantially central portion in the depth direction of the lower sliding portion 71 h. The lower end of the coupling shaft 71k protrudes below the lower plate portion 70 b.

The rod main body 71j is formed in a rod shape extending downward from the lower end of the connecting shaft 71 k.

The front surface portion 71m, which is a surface in the-Y direction in the rod main body 71j, extends linearly downward, and then is gradually bent in the-Y direction at the lower end portion. Therefore, the front surface portion 71m is J-shaped when viewed from the-X direction.

On the other hand, the rear surface portion 71n, which is the surface in the + Y direction in the lever main body 71j, is a flat surface extending linearly downward.

As described above, the slide member 71 has a T-shape when viewed from the-X direction.

The lever main body 71j of the operation lever 71B may have a length enough to be able to hold the finger F.

The longer the length of the slider 71A is, the more stable the forward and backward movement of the slider 71A is, and therefore, this is preferable.

As shown in fig. 3, the 2 nd case 56B has the same configuration as the 1 st case 56A, except that a case main body 56aB is provided instead of the case main body 56 aA. The cartridge body 56aB may be the same member as the cartridge body 56aA, or may be a member different in size, shape, or the like from the cartridge body 56 aA.

The 2 nd box 56B can be accommodated in a range from the inner surface of the protruding portion 61a of the rib 61C to the center of the flat surface portion 61B of the rib 61B in the lateral width direction.

The 3 rd cartridge 56C has the same configuration as the 1 st cartridge 56A, except that a cartridge main body 56aC is provided instead of the cartridge main body 56 aA. The width in the lateral width direction of at least the + Y direction end of the case body 56aC is narrower than the distance in the lateral width direction between the rail portions 64A, 64C. The 3 rd container 56C includes, instead of the 1 st and 2 nd walls 56b and 56C in the 1 st container 56A, a1 st and 2 nd walls 56bC and 56cC each having a shorter length in the lateral width direction.

However, the length of the locking projection 57L in the vertical direction in the 3 rd case 56C is shorter than the vertical gap of the gap 64 i. Therefore, the locking projection 57L in the 3 rd case 56C can move in the depth direction through the gap 64 i.

The length of the locking projection 57R in the vertical direction in the 3 rd case 56C is also the same as the locking projection 57L.

The type of the content in the 3 rd cartridge 56C is not particularly limited, as in the 1 st cartridge 56A. The 3 rd box 56C may contain specific contents each having a certain height, such as a can container, a bottle container, a carton beverage, and an egg.

In this case, a tray member corresponding to the shape of a specific storage may be disposed inside the 3 rd box 56C. In the example shown in fig. 3, an egg tray 56h for storing the contents 82 is disposed inside the 3 rd box 56C.

Here, the moving range of each cartridge 56 in the example shown in fig. 3 will be described.

Fig. 11 is a sectional view illustrating a moving range of a door container in a refrigerator of an embodiment.

The 1 st case 56A1 shown in fig. 11 shows the position of the 1 st case 56A when the engagement portion 71a, not shown, is engaged with the groove portion 61c1, which is the uppermost groove portion 61c of the concave-convex engagement portions Ea.

Similarly, the 1 st case 56A2 shows the lowermost position of the 1 st case 56A where the locking projection 57L, not shown, is locked to the 1 st stopper 53d from above. At this time, as described above, the 1 st case 56A can be engaged with the groove portion 61c5 which is the 5 th groove portion 61c from the top.

In contrast, as described above, the 3 rd container 56C can be engaged with the groove portion 61C6 that is the 6 th groove portion 61C from the top. However, in this case, in the case of the depth of the 1 st box 56A shown in fig. 11, the upper end of the 3 rd box 56C interferes with the lower surface of the 1 st box 56A 2. If the depth of the 1 st case 56A is made shallow or the 1 st stopper 53d is disposed further upward, interference can be prevented.

The 3 rd case 56C1 shows the position of the 3 rd case 56C when the engagement portion 71a, not shown, is engaged with the groove portion 61C7, which is the 7 th groove portion 61C from the top. In this case, a gap Δ 1 is formed between the lower surface of the 1 st box 56a2 and the upper end of the 3 rd box 56C 1.

Further, if the structure is adopted in which groove portion 61C6 is not provided at first, or the structure is adopted in which groove portion 61C6 is sealed and the engagement portion 71a cannot be engaged, the 3 rd container 56C1 is at the uppermost position. In this case, even if the 1 st case 56A falls along the guide rail portion 64, the 1 st case 56A and the 3 rd case 56C do not collide. The same applies to the contents whose amount of projection from the 3 rd container body 56C is smaller than Δ 1.

The 3 rd case 56C2 shows the position of the 3 rd case 56C when the engagement portion 71a, not shown, is engaged with the groove portion 61C11, which is the 11 th groove portion 61C from the top. In this case, a gap Δ 2 is formed between the lower surface of the 1 st box 56a2 and the upper end of the 3 rd box 56C 2. Here, if the arrangement pitch of the groove portions 61c is δ, Δ 2 is Δ 1+3 × δ. Therefore, if the depth of the 3 rd container 56C is z1, Δ 1+ z1 in the 3 rd container 56C1 and the content having a height smaller than Δ 2+ z1 in the 3 rd container 56C2 can be stored without interfering with the 1 st container 56a 2.

The 3 rd container 56C3 shows the position of the 3 rd container 56C when the locking projection 57L, not shown, of the 3 rd container 56C is locked to the 2 nd stopper 53e from above. In this case, a gap Δ 3 is formed between the lower surface of the 3 rd case 56C and the upper end 59C of the case 59.

The case 59 has a1 st receiving portion 59a and a2 nd receiving portion 59 b.

The 1 st receiving portion 59a has a bottom plate 59d placed on the 2 nd plate-like portion 61Gb of the rib 61G. The 1 st bottom plate 59d is inclined similarly to the 2 nd plate-like portion 61Gb, and is connected to the 1 st plate-like portion 61Ga with almost no step.

The 1 st plate-like portion 61Ga and the 1 st bottom plate 59d can accommodate the accommodated substance 83 in a state of being inclined in the + Y direction according to the inclined surfaces thereof.

The type of the storage 83 is not particularly limited. For example, the storage 83 may be a can container, a bottle container, a carton beverage, or the like.

The 2 nd receiving portion 59b protrudes in the + Y direction from the rib 61G and the 1 st receiving portion 59 a. The 2 nd accommodating portion 59b has a2 nd bottom plate 59e inclined similarly to the 1 st bottom plate 59d of the 2 nd plate-like portion 61 Gb. Therefore, the 2 nd accommodating portion 59b can accommodate the accommodated substance 84 in a state of being inclined in the + Y direction.

The type of the storage body 84 is not particularly limited. For example, the storage 84 can store an appropriate storage exemplified as the storage 83.

On each lateral side surface of the case 59 in the lateral width direction, an engaging projection 59f that can be inserted from above into a gap between the locking guide projection 53f and the locking projection 65 projects outward. These engaging projections 59f engage with the locking projections 65 and the locking guide projections 53f (see fig. 4A and 4B), and thereby the position of the case 59 in the depth direction in the rear surface member 53 is fixed.

Next, an engaging structure between the 1 st case 56A and the rear surface member 53 will be described. However, since the engagement structure in the rib 61A and the rail portion 64A is the same as the engagement structure in the rib 61B and the rail portion 64Ba, the engagement structure in the rib 61A and the rail portion 64A will be mainly described.

Fig. 12 is a sectional view illustrating a locked state of a door container in the refrigerator of the embodiment. Fig. 13 is a sectional view showing a lock released state of a door container in the refrigerator according to the embodiment.

As shown in fig. 12, in the 1 st case 56A in the locked state, the locking projection 57L is inserted into a space between the stepped portion 53c and the front surface 64d of the rail portion 64. The upper projection 57a and the lower projection 57b abut against the front surface 64d, respectively. A gap is formed between the flat portion 57d and the step portion 53 c.

The slider 71A is urged in the-Y direction by an elastic member 72. As a result, the slider 71A is guided by the 1 st guide plate 58b and the 2 nd guide plate 58c to move in and out in the-Y direction. The slider 71A protrudes in the-Y direction from the opening in the-Y direction in the cover 70.

The protruding engagement portion 71a is inserted into one of the recessed grooves 61c of the concave-convex engagement portion Ea. The upper locking portion 71e and the lower locking portion 71f press the flat surface portion 61b adjacent to the recessed portion 61c in a state of being biased by the elastic member 72. Thus, the longitudinal direction of the slider 71A is perpendicular to the planar portion 61 b.

Since only the protruding portions of the convex engagement portion 71a protruding from the upper locking portion 71e and the lower locking portion 71f are inserted into the groove portion 61c, a gap is formed between the front end surface 71d and the groove bottom portion 61 f.

Since the downward gravity acts on the 1 st case 56A, the lower engaging portion 71b engages with the flat portion 61 b. At this time, a gap is formed between the upper engagement portion 71c and the upper engagement portion 61 g. That is, the convex engagement portion 71a engages with the concave-convex engagement portion Ea in the-Z direction.

However, if an external force acts to lift the 1 st case 56A upward against its own weight, the slider 71A moves upward along the flat surface portion 61b according to the magnitude of the external force, and the upper engaging portion 71c engages with the upper sliding portion 71 g.

In this way, the elastic member 72 is provided so as to be able to press the concave-convex engagement portion Ea between the convex engagement portion 71a and the locking projection 57L via the guide rail portion 64A and the concave-convex engagement portion Ea.

The pressing force f of the elastic member 72 is transmitted to the flat surface portion 61b by the upper locking portion 71e and the lower locking portion 71f which are separated in the vertical direction.

Since the 1 st case 56A is pulled in the + Y direction by the reaction force of the pressing force, the upper convex portion 57a and the lower convex portion 57b press the front surface 64d in the + Y direction with the force f having the same magnitude as the pressing force.

The respective pressing positions in the plan view are not strictly on the same straight line, but are in a positional relationship in the vicinity of the side surface S of the rib 61A and substantially opposed to each other in the depth direction along the side surface S. Therefore, the rotational moment in the horizontal plane generated by the deviation of the pressing position in the lateral width direction is negligible.

In the present embodiment, as shown in fig. 12, the upper locking portion 71e and the lower locking portion 71f are in a positional relationship in which the upper protruding portion 57a and the lower protruding portion 57b in the vertical direction face each other in the depth direction. Therefore, a rotational moment in the vertical plane due to the deviation of the point of action of each pressing force is not generated, and the gripping state in the depth direction is stable.

The rear pressing region P1 between the pressing position of the upper locking portion 71e and the pressing position of the lower locking portion 71f in the vertical direction is not particularly limited as long as it overlaps with the front pressing region P2 between the pressing position of the upper protruding portion 57a and the pressing position of the lower protruding portion 57b in the vertical direction when viewed in the depth direction. However, as shown in the example of fig. 12, the rear side pressing region P1 is preferably located within the range of the front side pressing region P2.

According to the present embodiment, the pressing force f of the elastic member 72 in the-Y direction is transmitted to the rib 61A via the upper locking portion 71e and the lower locking portion 71f which are separated wider than the vertical width of the convex engagement portion 71A. Therefore, the rail portion 64 and the concave-convex engagement portion E are sandwiched by 2 points of the upper convex portion 57a and the lower convex portion 57b, 2 points of the upper locking portion 71E and the lower locking portion 71f, and 4 points in total, as viewed in the-X direction.

Therefore, the 1 st case 56A is less likely to rotate in the vertical plane intersecting the lateral direction than in the case where the pressing forces on the rail portion 64 and the concave-convex engagement portion E act at 1 point and 2 points in total, or 1 point and 2 points and 3 points in total, respectively. As a result, the 1 st case 56A is less likely to shake.

In such a locked state, the position in the up-down direction of the 1 st case 56A is fixed according to the position of the groove portion 61 c. In the present embodiment, the position of the 1 st case 56A in the vertical direction can be changed by releasing the locked state. However, since this operation is performed in a state where the right refrigerating compartment door 11Ab is opened, in fig. 13, a line extending in the rear direction (direction from the inside of the right refrigerating compartment door 11Ab toward the front surface plate 52) when the door is facing the front side is defined as a — η direction, and a line extending in the front direction when the door is facing the front side, which is opposite to the line, is defined as a + η direction.

To release the locked state, for example, as shown in fig. 13, the user places a finger F or the like on the operation lever 71B and retracts the slide member 71 toward the locking holder 73 (+ η direction).

If the operating rod 71B is pulled in the + η direction, the slider 71A moves in the + η direction. At this time, the elastic member 72 is compressed. The convex engaging portion 71A provided on the slider 71A is retreated from the groove portion 61 c. Thereby, the engagement between the slider 71A and the concave-convex engagement portion Ea is released.

If the amount of movement of the slider 71A is greater than the amount of projection d2 of the projecting engagement portion 71A, the distance between the locking projection 57L and the projecting engagement portion 71A is greater than the distance between the front surface 64d and the flat surface portion 61b, so that the locking projection 57L can be separated from the front surface 64d and the projecting engagement portion 71A can be separated from the flat surface portion 61 b.

Thereby, the 1 st case 56A on the + X direction side is unlocked (unlocked).

Similarly, in the case 1a, the locking projection 57R and the locking portion 58R on the side surface in the-X direction can be switched between the locked state and the unlocked state by sandwiching the rail portion 64Ba and the concave-convex engagement portion Eb therebetween. However, in the engagement structure in the rib 61B and the rail portion 64Ba, only the + X direction side in the lateral width direction of the concave-convex engagement portion Eb is used.

In the case 1 of the case 56A, when both the locked states of the respective lock portions 58 in the lateral direction are released, the vertical movement is possible. Therefore, when only one operation lever of lock portion 58 is moved when the stored items are taken out of or put into refrigerating compartment 27A, case 1a does not fall down.

In the present embodiment, the front surface 64d and the stepped portions 53c and 53g of the rail portions 64A and 64Ba are both flat surfaces extending in the vertical direction. Thus, in the unlocked state, the locking projections 57L and 57R can be smoothly moved in the vertical direction along the gaps Ga and Gba between the front surface 64d and the stepped portions 53c and 53g, respectively.

Similarly, in the 2 nd case 56B, the guide rail portion 64Bc and the concave-convex engagement portion Eb are sandwiched between the locking projection 57L and the locking portion 58L on the side surface in the + X direction, and the locked state and the unlocked state can be switched. However, in the engagement structure in the rib 61B and the rail portion 64Ba, only the-X direction side in the lateral width direction of the concave-convex engagement portion Eb is used.

Further, in the case 2B, the locking projection 57R and the locking portion 58R on the side surface in the-X direction can be switched between the locked state and the unlocked state by sandwiching the guide rail portion 64C and the concave-convex engaging portion Ec therebetween.

Similarly, in the case 3C, the locking projection 57L and the locking portion 58L on the + X-direction side face can be switched between the locked state and the unlocked state by sandwiching the guide rail portion 64A and the concave-convex engagement portion Ea therebetween.

Further, in the case 3C, the locking projection 57R and the locking portion 58R on the side surface in the-X direction can be switched between the locked state and the unlocked state by sandwiching the guide rail portion 64C and the concave-convex engaging portion Ec therebetween.

The right refrigerating chamber door 11Ab has been described above, but the left refrigerating chamber door 11Aa has the same configuration except that the widths in the opening and closing direction and the lateral width direction are different.

The internal configuration of the left refrigerating chamber door 11Aa is not particularly illustrated, but the same internal configuration as that of the right refrigerating chamber door 11Ab may be used.

However, the rib 61B may be omitted depending on the width of the left refrigerating compartment door 11Aa in the lateral width direction, for example. In this case, a box similar to the 3 rd box 56C may be disposed in the left refrigerating chamber door 11Aa at the upper and lower sides.

Next, the operation of the refrigerator 1 will be mainly described with respect to the operation of attaching and detaching the box 56.

Fig. 14 and 15 are sectional views illustrating an operation of attaching and detaching the door container in the refrigerator according to the embodiment.

Each cartridge 56 is attached to and detached from the rear surface member 53 in the unlocked state described above in a state where the right refrigerating compartment door 11Ab is opened.

For example, when the 1 st case 56A is attached to the rear surface member 53, the operator uses the finger F to set the lock portion 58La to the lock release state and inserts the lock portion in the- η direction toward the gap 64h between the upper surface 64e and the rib 61F, as in the 1 st case 56Aa shown by the two-dot chain line in fig. 14.

Although not particularly shown, similarly, the lock portion 58R is also in the unlocked state and inserted in the- η direction toward the gap between the upper surface 64e of the rail portion 64Ba and the rib 61F.

After the locking projection 57L is inserted to the extent that it abuts the step portion 53c and the locking projection 57R (not shown) abuts the step portion 53g (not shown), the 1 st case 56A is lowered (moved in the-Z direction).

The following mainly describes the operation of the 1 st case 56A shown in fig. 14 on the + X direction side surface.

After the 1 st case 56A is further lowered, the locking projection 57L is inserted between the stepped portion 53c and the front surface 64d of the guide rail portion 64A.

Thus, as shown in fig. 13, the 1 st case 56A can move vertically along the gap Ga between the front surface 64d and the stepped portion 53 c. In the present embodiment, since the operating lever 71B extends downward from the substantially central portion of the slider 71A, the finger F is disposed in a space between the- η -direction distal end portion of the slider 71A and the front surface portion 71m of the operating lever 71B. In the present embodiment, a gap into which the finger F can be inserted is formed between the flat surface portion 61B and the front surface portion 71m in the movable range of the operation lever 71B even when the operation lever is moved in the- η -most direction. Therefore, the finger F is not sandwiched by the rib 61A and the operation lever 71B.

Further, since each of the operation levers 71B is positioned in the + η direction with respect to the ribs 61A, 61B, and 61C, the operator can easily see it. For example, after the operator releases the finger F, it is easy to put the finger F on the operation lever 71B again.

The operator moves the 1 st box 56A in the up-down direction to an appropriate position where the 1 st box 56A is desired to be fixed. At this time, since the concave-convex engagement portions Ea and Eb can be seen from the operator, the position of the groove portion 61c with which the convex engagement portion 71a is engaged can be confirmed in advance.

The operator moves the 1 st container 56A to the proper position, and then releases the force of the finger F. The slide member 71 is moved in the- η direction by the urging force from the elastic member 72.

At this time, the groove portion 61c is present in the- η direction, and when a part of the projecting engagement portion 71a enters the groove portion 61c, the locked state shown by the solid line in fig. 14 is formed.

That is, as shown in fig. 6, since the upper bent portion 61h and the lower bent portion 61d are formed in the vicinity of the groove portion 61c from the flat surface portion 61b toward the groove portion 61c, even if the convex engaging portion 71a is slightly displaced in the vertical direction from the position of the groove portion 61c, it is guided to the upper engaging portion 61g along the upper bent portion 61h or guided to the lower engaging portion 61e along the lower bent portion 61 d.

In particular, when the convex engaging portion 71a abuts against the upper bent portion 61h or the upper engaging portion 61g, the reaction force component from these portions also coincides with the direction of the self-weight component of the 1 st case 56A, so that the 1 st case 56A is more smoothly lowered. Thus, the lower engagement portion 71b abuts against the flat surface portion 61 b.

On the other hand, when the convex engagement portion 71a is largely deviated from the groove portion 61c, the tip of the convex engagement portion 71a abuts against the flat surface portion 61 b. In this case, the operator moves the 1 st case 56A in the vertical direction, so that the convex engagement portion 71a enters the adjacent recessed groove portion 61c, and the locked state is formed as described above.

When the position of the 1 st case 56A in the locked state is not as intended, the operator can engage the convex engagement portion 71a with the other recessed groove portion 61c in the same manner as described above after pulling the operation lever 71B in the + η direction to form the unlocked state.

In the present embodiment, the groove portion 61c is formed with an upper engaging portion 61g inclined in the + Z direction toward the + Y (+ η) direction, and a lower flat portion 61b extending horizontally. Therefore, if the convex engagement portion 71a moves to a certain extent in the + η direction, it can easily move to a certain extent upward along the upper engagement portion 61 g. However, it is difficult to lower the 1 st case 56A within a range overlapping the flat surface portion 61 b. Therefore, the 1 st container 56A is less likely to fall during release of the locked state.

Further, in the present embodiment, since the lower bent portion 61d is formed below the opening of the recessed groove portion 61c, even if the convex engagement portion 71a moves in the + η direction with respect to the flat surface portion 61b, abrupt falling is suppressed within the range of the lower bent portion 61 d.

Similarly, since the upper bent portion 61h is formed above the opening of the recessed groove portion 61c, even if the convex engagement portion 71a moves in the + η direction with respect to the upper engagement portion 61g, a sudden rise is suppressed in the range of the upper bent portion 61 h.

This suppresses abrupt vertical movement of the 1 st case 56A during the release of the locked state.

In particular, if R2 is larger than R1, the upper curved portion 61h is bent more largely than the lower curved portion 61d, and therefore resistance to upward movement required for the force to lift the 1 st container 56A is reduced. This allows the 1 st case 56A to move upward smoothly.

The 1 st case 56A shown by a solid line in fig. 14 is engaged with the uppermost recessed groove portion 61c of the concave-convex engaging portion Ea.

The 1 st case 56A can be engaged with any one of the 1 st to 5 th recessed grooves 61c of the concave-convex engaging portion Ea from above.

However, in the present embodiment, since the 1 st stopper 53d is provided, the locking projection 57L cannot move downward than the 1 st stopper 53d as the locking projection 57Lb shown by the two-dot chain line. As a result, even if the locking portions 58 of the 1 st case 56A are unintentionally unlocked or, in case of a failure, unlocked, the 1 st case 56A does not fall below the engagement position with the 5 th recessed groove portion 61c from above.

Therefore, the contents in the 3 rd box 56C and the 3 rd box 56C, which are lower than the lowermost lower surface of the 1 st box 56A, are not damaged by the 1 st box 56A falling down along the guide rail portion 64.

In the present embodiment, the gap 64h is provided above the engageable movement range of the 1 st case 56A. Therefore, the 1 st case 56A can be prevented from being detached in the + Y direction (+ η direction) while the user is changing the position of the 1 st case 56A in the vertical direction.

Next, an example of a case where the 3 rd case 56C is fitted to the rear surface member 53 will be described. However, as in the case of the 1 st case 56A, the end portions of the 3 rd case 56C in the + X direction will be mainly described.

To attach the 3 rd case 56C to the rear surface member 53, the operator inserts the lock portion 58La in the- η direction toward the gap 64i with the finger F in the unlocked state as in the 3 rd case 56Ca shown by the two-dot chain line in fig. 15.

After the locking projection 57La is inserted to the extent of abutting against the stepped portion 53C as the locking projection 57Lb shown by the two-dot chain line, the operator moves the 3 rd container 56C in the vertical direction.

For example, the operator may raise the 3 rd cassette 56C as shown by the solid line in the 3 rd cassette 56C.

In the present embodiment, the gap 64i is provided below the engageable movement range of the 3 rd container 56C. Therefore, the 3 rd box 56C can be prevented from being detached in the + Y direction (+ η direction) while the user is changing the position of the 3 rd box 56C in the vertical direction.

For example, the operator may temporarily lower the 3 rd container body 56C to a position where the locking projection 57Lc is locked to the 2 nd stopper 53e from above, as shown by the locking projection 57Lc indicated by the two-dot chain line. In this case, the locking projection 57Lc is locked to the 2 nd stopper 53e, and the lowering of the 3 rd container 56C is stopped, so that the operator can release his or her hand from the 3 rd container 56C.

The operator can move the 3 rd box 56C upward to form the locked state in the same manner as the 1 st box 56A described above. In the case of the 3 rd cartridge 56C, the locking state can be established in any one of the 6 recessed grooves 61C on the lower side of the concave-convex engagement portion Ea.

For example, the 3 rd box 56C shown by a solid line in fig. 15 is engaged with the 2 nd recessed groove portion 61C from the bottom in the concave-convex engaging portion Ea.

In the present embodiment, since the 2 nd stopper 53e is provided on the ribs 61A and 61C, the respective locking projections 57 cannot move downward from the 2 nd stopper 53 e. As a result, even if the locking portions 58 of the 3 rd cartridge 56C are unintentionally unlocked or, in case of a failure, unlocked, the falling position of the 3 rd cartridge 56C is restricted by the 2 nd stopper 53 e. Therefore, the 3 rd box 56C does not fall further downward than the 3 rd box 56C3 shown in fig. 11. That is, the case 59 and the stored objects 83 and 84 in the case 59, which are located lower than the lowermost lower surface of the 3 rd case 56C, are not damaged by the 3 rd case 56C falling down along the guide rail portion 64.

Further, in a state where the locking projection 57L is locked to the 2 nd stopper 53e, as shown by the locking projection 57Lc, the 2 nd rail portion 64b, which is a part of the rail portion 64A, is arranged below the gap 64i in the + η direction. Therefore, as long as the operator does not pick up the 3 rd case 56C, the 3 rd case 56C does not pass through the gap 64i to be offset in the + η direction.

Similarly, when the 3 rd cartridge 56C is dropped along the rail portion 64 while moving in the vertical direction, the 3 rd cartridge 56C passes through the- η side of the gap 64i and drops onto the 2 nd stopper 53 e. At this time, the 2 nd rail portion 64b is positioned in the + η direction of the 2 nd stopper 53e with respect to the locking projection 57L. Therefore, the locking projection 57L needs to go over the 2 nd rail portion 64b to move further in the + η direction. This can prevent the 3 rd case 56C from flying out in the + η direction through the gap 64 i.

As described above, according to the refrigerator 1 of the present embodiment, for example, the box body 56 can move in the vertical direction between the ribs 61 along the guide rail portion 64 at the right refrigerating compartment door 11 Ab. A1 st stopper 53d and a2 nd stopper 53e for restricting the lowering position of the box 56 are provided between the rail portion 64 and the inner surface portion 53 a. Thus, even if the cartridge 56 falls when the arrangement position of the cartridge 56 is changed, damage to the cartridge 56 and the contents in the cartridges 56 and 59 can be suppressed.

In particular, the rail portion 64 has a gap 64i for facilitating the attachment and detachment of the 3 rd container 56C, but the 2 nd rail portion 64b is provided below the gap 64i, so that the 3 rd container 56C can be prevented from falling out of the gap 64 i.

In the above embodiment, the example in which the gripping mechanisms at both side portions of each door are bilaterally symmetrical has been described, but at least one of the structure and the arrangement of each gripping mechanism may not be bilaterally symmetrical. In this case, at least one of the shapes and the arrangement of the concave-convex engaging portion and the guide rail portion that engage with each of the gripping mechanisms may be made asymmetric in the left-right direction.

In the above embodiment, the case where the groove portion 61c of the rib 61B penetrates the tip end portion of the rib 61B in the lateral width direction has been described. In this case, since the gap between the lock portion 58R of the 1 st case 56A and the lock portion 58L of the 2 nd case 56B can be narrowed, the housing space of the 1 st case 56A and the 2 nd case 56B can be increased.

However, when the housing space of the 1 st case 56A and the 2 nd case 56B is still left, the recessed groove portions 61c may be divided in the lateral direction. For example, the groove portion 61c may be divided into left and right sections at the center portion in the thickness direction of the rib 61B, and a rib such as a rib protruding from the groove portion 61c may be provided.

In the above embodiment, the case where the engaging portion of the clamping mechanism has a convex engaging portion that engages with the concave portion of the concave-convex engaging portion has been described. However, the engaging portion of the clamping mechanism may be a concave engaging portion that engages with the convex portion of the concave-convex engaging portion.

In the above embodiment, the case where 2 abutting portions are provided at a portion of the engaging portion of the gripping mechanism so as to be separated in the vertical direction has been described. However, the contact part may be provided at 1 position, or may be provided at 3 or more positions.

Further, the abutting portion may not be provided as long as the engaging portion can engage with the concave-convex engaging portion in a direction intersecting the vertical direction and the lateral width direction.

In the above-described embodiment, the case where the slide member having the engaging portion is relatively moved with respect to the cartridge in the clamping mechanism, and the clamping mechanism grips the guide rail portion and the concave-convex engaging portion has been described. However, at least one of the engaging portion and the engaging projection may be relatively moved with respect to the case as long as the clamping mechanism can hold the guide rail portion and the concave-convex engaging portion.

In the above embodiment, the case where the case has the locking projection, and the stopper is locked to the locking projection to regulate the lowering position of the case has been described. However, the stopper may be locked to the case other than the locking projection as long as the stopper can restrict the lowering position of the case. For example, the stopper may be engaged with a concave-convex shape formed on a surface of the case other than the engaging projection. For example, the stopper may be locked to the lower surface of the case.

In the above embodiment, the stopper is provided between the guide rail portion and the stepped portion. In this case, since the guide rail portion and the stepped portion form a movement path of the locking projection, the lowering position of the case can be regulated by preventing the locking projection from moving. For example, if the stopper and the rail portion are connected to the step portion like the 1 st stopper 53d, there is an advantage that the strength of the stopper is improved by the rail portion and the step portion.

However, the stopper may be provided between the guide rail portion and the inner surface portion within a range in which the case is lowered. The arrangement of the stopper is not limited to between the rail portion and the stepped portion. Further, if the cassette can be lifted, the inner surface portion may not have a step portion.

Further, the stopper may not be formed at a position sandwiched between the guide rail portion and the inner surface portion as long as the stopper can restrict the lowering position of the cartridge.

For example, in the case where the lowering position of the cassette is set lower than the lower end of the rail portion, the stopper may be disposed lower than the rail portion as long as it is located between the rail portion and the inner surface portion when viewed from above.

In this case, the slide guide may further include a slip-off prevention portion which is disposed below the guide rail portion with a gap between the slip-off prevention portion and the lower end of the guide rail portion, the gap allowing the locking protrusion to move forward and backward in the 1 st direction, and which restricts movement of the locking protrusion locked to the stopper in the 1 st direction. For example, in the above embodiment, the 2 nd rail portion also serves as the slip-off preventing portion, but the slip-off preventing portion may not constitute the rail portion together with the 1 st rail portion 64 a. For example, the slip-off prevention portion may be formed of 1 or more rod-shaped protrusions protruding inward from the side surface S.

In the above embodiment, the case where the concave-convex engaging portion E and the rail portion 64 are held by the holding mechanism 60, and the case is engaged with the 1 st wall portion and the 2 nd wall portion has been described. However, the engaging structure of the cartridge with the 1 st wall part and the 2 nd wall part is not limited to such an engaging structure.

In the above embodiment, the case where each locking protrusion is constituted by 1 protrusion long in the vertical direction has been described. However, each of the locking projections may be a plurality of projections separated in the vertical direction and projecting in the lateral width direction. Further, the shape of the locking projection is not limited to a vertically long shape. For example, the shape of the locking projection may have a round bar shape or a square bar shape having substantially the same length in the vertical direction and the depth direction.

In the above embodiment, the case where the stopper is constituted by 1 protrusion, each of which is long in the vertical direction, provided between the guide rail portion and the inner surface portion has been described. However, each of the locking projections may be a plurality of projections separated in the vertical direction and projecting in the lateral width direction. Further, the shape of the locking projection is not limited to a vertically long shape. For example, the shape of the locking projection may have a round bar shape or a square bar shape having substantially the same length in the vertical direction and the depth direction.

In the above embodiment, the case where the rail portions protrude from the side surfaces of the 1 st wall portion and the 2 nd wall portion facing each other has been described. However, the configuration of the guide rail portion is not limited thereto. The rail portion may not protrude from the side surface of the 1 st wall portion and the 2 nd wall portion as long as the rail portion is vertically aligned with the side surface facing each other.

For example, the rail portion may be recessed inward from the side surface. In this case, the locking projection may be movable in the vertical direction along the inner surface of the guide rail portion in a state where at least a part of the locking projection is inserted into the inside of the guide rail portion.

For example, the rail portion may have a portion protruding from the side surface and a portion recessed inward of the side surface.

According to at least one embodiment described above, it is possible to provide a refrigerator in which the door container can move in the vertical direction between the 1 st wall portion and the 2 nd wall portion along the guide rail portion, and a stopper for restricting the lowering position of the door container is provided between the guide rail portion and the inner surface portion, and therefore, even if the door container drops when the arrangement position of the door container is changed, damage to the door container and the stored object on the door can be suppressed.

Several embodiments of the present invention have been described above, but these embodiments are merely examples and are not intended to limit the scope of the invention. These embodiments may be implemented in other various forms, and various omissions, substitutions, and changes may be made without departing from the spirit of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are also included in the invention described in the claims and the equivalent scope thereof.
