Detailed Description

Embodiments of the present invention will be described below with reference to the drawings. In the following description, the same components are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed description thereof will not be repeated.

< first embodiment >

(integral constitution of refrigerator)

First, the overall configuration of the refrigerator 1 of the first embodiment is explained. Fig. 1 shows an appearance of a refrigerator 1 as viewed from the front.

The refrigerator 1 is mainly constituted by an insulated cabinet 90 in its outer shape. A storage space of the refrigerator 1 is formed by the heat insulation box 90. The storage space formed by the heat-insulating box 90 is divided into, for example, a refrigerating chamber 11, a vegetable chamber 12, an ice-making chamber 14, a second freezing chamber 15, and a freezing chamber 13 in this order from the upper stage by a plurality of partitions extending in the horizontal direction.

Left and right split type refrigerating chamber doors 11a and 11b are provided in the refrigerating chamber 11. A drawer-type vegetable compartment door 12a is provided in the vegetable compartment 12. A drawer-type freezing chamber door 13a is provided in the freezing chamber 13. A drawer type ice making chamber door 14a is provided in the ice making chamber 14. A drawer-type freezing chamber door 15a is provided in the second freezing chamber 15.

As described above, the refrigerator 1 of the present embodiment is divided into a plurality of storage spaces, and includes the refrigerating chamber 11, the vegetable chamber 12, and the like. However, the arrangement position of each storage space is not limited to this. The configuration of the door provided in each storage space is not limited to the above.

In the present embodiment, the surface provided with the door is referred to as a front surface or a front surface of the refrigerator. The respective surfaces of the refrigerator 1 are an upper surface, a side surface, a rear surface, and a bottom surface based on positions that exist when the refrigerator 1 is installed in a normal state with the front surface as a reference. In addition, a left-right direction (a lateral direction orthogonal to the up-down direction) when the refrigerator 1 is viewed from the front in a state where the refrigerator 1 is placed on a mounting surface is referred to as a left-right direction of the refrigerator 1 (or the vegetable compartment door 12a or the like). In a state where the refrigerator 1 is placed on a mounting surface, a vertical direction of the refrigerator 1 (a vertical direction orthogonal to the left-right direction) is referred to as a vertical direction of the refrigerator 1 (or the vegetable compartment door 12a or the like). Further, a side on the left side as viewed from the front surface side of the refrigerator 1 is referred to as a left side of the refrigerator 1, and a side on the right side as viewed from the front surface side of the refrigerator 1 is referred to as a right side of the refrigerator 1.

In addition, in the present embodiment, a handle portion 31 is provided at an upper end portion of each door of the drawer type (i.e., the vegetable compartment door 12a, the freezing compartment door 13a, the ice making compartment door 14a, the freezing compartment door 15a, and the like). A seal member 61 (see fig. 2) is attached to the inclined surface around the grip portion 31. The surface around the grip portion 31 may not be an inclined surface, and may be a surface parallel to the front surface of the door, for example.

Various patterns such as wood grain patterns and marble patterns are printed on the surface of the attachment member 61 in various colors. This can improve the design of the appearance of the refrigerator 1. The attaching part 61 is also referred to as a decorative sheet.

An adhesive layer containing an adhesive material is formed on the back surface of the joining member 61. Therefore, the user can select the pasting member 61 having a desired pattern from the plurality of pasting members 61 printed with different patterns, and paste the selected pasting member 61 around the handle portion 31 of each door of the refrigerator 1. Further, another adhesive member 61 may be attached to the already attached surface of the adhesive member 61. Thus, the user can easily change the design of the front portion of the refrigerator 1 in accordance with the interior of the room in which the refrigerator 1 is installed.

(construction of vegetable room door)

Next, a more detailed configuration of the vegetable compartment door (refrigerator door) 12a provided in the refrigerator 1 will be described. Fig. 2 and 3 show the appearance of the vegetable compartment door 12a as viewed from the front side. In fig. 2, an attaching part 61 attached to the handle part 22 of the vegetable compartment door 12a is also illustrated.

The vegetable compartment door 12a mainly includes a metal plate 21, a handle member (cover member) 22, a reinforcing member 23, a lower cover member 24, a back surface member (not shown), a heat insulating material (not shown), and the like. The vegetable compartment door 12a is formed in an outer shape by a metal plate 21, a handle member (cover member) 22, a reinforcing member 23, a lower cover member 24, and a back surface member (not shown).

The metal plate 21 is disposed in front of the door. The metal plate 21 is formed by bending each end edge of 1 steel plate having a substantially rectangular shape, for example. The metal plate 21 has a front surface portion 21a, side surface portions 21b and 21b provided on both left and right sides, and bent portions 41 and 41 provided on both upper and lower sides. The plate member forming the front surface of the door may be a glass or resin member. The front surface of the door may be formed of another member such as metal or glass, and the outer peripheral portion may be formed of resin.

The handle member (cover member) 22 is attached to the upper end edge of the metal plate 21. The handle member 22 is formed by molding a resin material such as ABS, PP, or PS. In the present embodiment, the handle member 22 is attached to the bent portion 41 on the upper side of the metal plate 21. The grip member 22 has a grip portion 31, and the grip portion 31 has a recess 31a formed along the longitudinal direction thereof.

The reinforcing member 23 is a member for reinforcing a joint portion of the metal plate 21 and the handle member 22. As described later, the reinforcing member 23 is provided to cover the joint portion of the metal plate 21 and the handle member 22 from the inside of the door. The reinforcing member 23 is formed by molding a resin material such as ABS, PP, or PS.

The lower cover member 24 is attached to the lower end edge of the metal plate 21. The lower cover member 24 is formed by molding a resin material such as ABS, PP, PS, or the like, similarly to the handle member 22. In the present embodiment, the lower cover member 24 is attached to the bent portion 41 on the lower side of the metal plate 21.

The metal plate 21, the handle member 22, the reinforcing member 23, and the lower cover member 24 form the outer shape of the front side of the vegetable compartment door 12 a. Fig. 4 shows an internal configuration of a front side portion of the vegetable compartment door 12a (a configuration of a rear side of the front side portion) formed by these components.

The back surface member is formed by molding a resin material such as ABS, PP, or PS. The back member is attached so as to cover the back portions of the respective members shown in fig. 4. Thereby, the outer shape of the door is formed.

The heat insulating material is provided inside the door exterior body formed by combining these components. The heat insulating material is formed by filling a foamed heat insulating material such as foamed polyurethane into the interior of the door exterior body.

In the present embodiment, the attaching member 61 can be attached around the handle portion 31 provided at the upper end portion of the vegetable compartment door 12 a. This surface is an inclined surface (i.e., inclined surface portion 32) inclined with respect to the front surface of the door. In fig. 2, the vegetable compartment door 12a and the attaching part 61 attached thereto are shown in a state of being disassembled.

In the present embodiment, an inclined surface portion 32 is also provided around the handle portion 31 of the drawer-type door (e.g., the freezing chamber door 13a, the ice-making chamber door 14a, the freezing chamber door 15a, etc.) other than the vegetable chamber door 12 a. A sticking member (sheet member) 61 (see fig. 1 and 10) similar to the vegetable compartment door 12a is stuck to the inclined surface portion 32 of each door.

(constitution of Joint portion between Metal plate and handle Member)

Next, a more detailed structure of the joint portion between the metal plate 21 and the grip member 22 will be described. Fig. 5 shows a structure of a joint portion between the metal plate 21 and the handle member 22. Fig. 5 is a sectional view of a line a-a portion of the vegetable compartment door shown in fig. 2. Fig. 6 shows a state where the reinforcing member 23 is attached to the joint portion between the metal plate 21 and the handle member 22.

Fig. 8 shows a structure of a joint portion between the handle member 22 and the reinforcing member 23. Fig. 8 is a sectional view of the handle member 22 and the reinforcement member 23 at a position corresponding to a line B-B of the vegetable compartment door 12a shown in fig. 2.

As described above, the reinforcing member 23 is attached to the joint portion between the metal plate 21 and the handle member 22. Therefore, first, the respective configurations of the members (the metal plate 21, the handle member 22, and the reinforcing member 23) constituting the joint portion will be described. Fig. 7 shows a front side structure of the handle member 22.

The metal plate 21 is formed by bending each end edge of 1 steel plate having a substantially rectangular shape, for example. The metal plate 21 is mainly composed of a front surface portion 21a, side surface portions 21b and 21b on both left and right sides, and bent portions 41 and 41 on both upper and lower sides.

The front portion 21a forms a front portion of the vegetable compartment door 12 a. The side surface portions 21b form side surface portions on both left and right sides of the vegetable compartment door 12 a. The upper bent portion 41 is formed by bending a part of the upper end of the metal plate 21 to the back side. The lower bent portion 41 is formed by bending a part of the lower end portion of the metal plate 21 to the back side.

At least one hole 42 is formed in the upper bent portion 41 (see fig. 5).

The grip member 22 has a grip portion 31, an inclined surface portion 32, a narrow portion 33, and the like on the front surface side thereof.

The handle portion 31 is provided to extend from the center of the upper end of the vegetable chamber door 12a to the left and right. The grip portion 31 has a recess 31a (see fig. 5) recessed downward. The concave portion 31a extends in the longitudinal direction of the grip member 22 depending on the position of the grip portion 31.

The inclined surface portions 32 are provided on both left and right sides of the grip portion 31. The inclined surface portion 32 is inclined forward from above toward below. As described above, the attachment member 61 is attached to the inclined surface portion 32. This can improve the design of the front side of the refrigerator 1.

The narrow width portion 33 is a part of the inclined surface portion 32. The width of the narrow portion 33 in the vertical direction is narrower than the inclined surface portions 32 located on both the left and right sides of the grip portion 31. The narrow portion 33 is provided below the grip portion 31 along the formation region of the grip portion 31.

The attachment member 61 attached to the vegetable compartment door 12a has a shape matching the shape of the inclined surface portion 32 and the narrow width portion 33 provided in the handle member 22 (see fig. 2).

At least one recess (depressed portion) 36 is provided in the inclined surface portion 32 along the side of the joint portion to be joined to the metal plate 21. The recess 36 is a portion where a part of the resin forming the handle member 22 is shaved off. In the example shown in fig. 2, 4 dimples 36 are provided near the lower edge of the left-side inclined surface portion 32 of the vegetable compartment door 12a, and 4 dimples 36 are provided near the lower edge of the right-side inclined surface portion 32 of the vegetable compartment door 12 a. Such a recess 36 can be formed by providing a protrusion corresponding to the recess in a mold used for resin molding (e.g., injection molding) of the handle member 22.

In the present embodiment, a plurality of dimples 36 are provided. Further, the lateral width of one pit 36 is preferably 1cm or less. Accordingly, the size of the recess 36 can be made smaller than the width of a finger of an ordinary person, and the user can be prevented from feeling a sense of incongruity due to the recess 36 when touching the inclined surface portion 32.

Further, the recess 36 is preferably provided at a position slightly spaced apart from the end edge of the inclined surface portion 32 on the side of the joint portion with the metal plate 21. This makes it possible to provide the adhesive member of the adhesive member 61 outside the recess 36, and to prevent the adhesive member 61 from being peeled off.

Further, the grip member 22 is provided with a claw portion 34, a second claw portion 35, a thinned portion (second recessed portion) 37, an insertion groove 38, a pressing portion 39, and the like on the inner side (see fig. 5, 8, and the like).

The claw portion 34 is provided on the lower surface of the narrow portion 33. The claw portions 34 engage with holes 42 provided in the bent portions 41 of the metal plate 21 (see fig. 5). Thereby, the handle member 22 is attached to the metal plate 21.

The second claw portions 35 are provided at both left and right end portions of the back surface side of the recessed portion 31 a. The second claw portions 35 are fitted into openings 57 provided at both ends in the longitudinal direction of the reinforcing member 23 (see fig. 6). Thereby, the reinforcing member 23 is attached to the handle member 22.

The thinned portion 37 is provided on the back surface portion 32b located on the back surface side of the inclined surface portion 32. That is, the thinned portions 37 are provided on the back surface portions 32b located on both the left and right sides of the grip portion 31 (see fig. 4). The thinned portion 37 is a portion where a part of the resin forming the handle member 22 is cut away (see fig. 8). Such a thinned portion 37 can be formed by providing a protrusion corresponding to the thinned portion in a mold used for resin molding (e.g., injection molding) of the handle member 22. The thinned portion 37 is provided at a position not overlapping with the recess 36 provided on the inclined surface portion 32 side in front view.

The fitting groove 38 is provided below the inclined surface portion 32 (see fig. 7 and 8). When the handle member 22 is attached to the metal plate 21, a part of the bent portion 41 of the metal plate 21 is inserted into the insertion groove 38.

The pressing portion 39 is provided below the fitting groove 38. The pressing portion 39 supports the front surface portion 21a of the metal plate 21 from the back surface side in a state where the bent portion 41 of the metal plate 21 is inserted into the fitting groove 38 (see fig. 4). This can prevent the foamed heat insulating material from leaking from the joint between the metal plate 21 and the grip member 22.

The reinforcing member 23 is provided to cover the joint portion of the metal plate 21 and the handle member 22 from the inside of the door. As shown in fig. 4, the reinforcing member 23 is disposed along the formation position of the grip portion 31 (i.e., the recess 31a) of the grip member 22. The reinforcing member 23 is formed by molding (e.g., injection molding) a resin material such as ABS, PP, PS, or the like.

The reinforcing member 23 includes a front surface portion 51, an upper surface portion 52, a rear portion 53, left and right side portions 54, and the like (see fig. 5 and 6). Names of the respective parts of these reinforcing members 23 are defined based on positions of the reinforcing members 23 in a state of being mounted on the vegetable compartment door 12 a.

At least one recess 56 is provided in the upper surface portion 52 of the reinforcing member 23. The recess 56 is provided at a position corresponding to the hole 42 provided in the metal plate 21 and the claw 34 provided in the handle member 22 (see fig. 5).

The side portion 54 is provided with an opening 57. The second claw portion 35 provided in the handle member 22 is fitted into the opening portion 57. Thereby, the reinforcing member 23 is attached to the handle member 22.

The reinforcing member 23 is provided to cover a joint portion between the metal plate 21 and the handle member 22 from the inside of the door (see fig. 4, 6, and the like). By providing such a reinforcing member 23, the gap formed between the metal plate 21 and the handle member 22 can be narrowed or closed. This can suppress leakage of the foamed heat insulating material filled in the door. Further, the positional deviation of the metal plate 21 can be suppressed.

When the handle member 22 is attached to the metal plate 21, the bent portion 41 of the metal plate 21 is inserted into the fitting groove 38 of the handle member 22. Then, the claw portion 34 of the handle member 22 is engaged with the hole 42 provided in the bent portion 41 (see fig. 5).

After the handle member 22 is attached to the metal plate 21, the reinforcing member 23 is attached. The reinforcing member 23 is attached to the handle member 22 from below the handle member 22 (see fig. 6). Therefore, the opening 57 of the reinforcing member 23 is moved from the lower side of the second claw 35 of the grip member 22 to the position where the second claw 35 is disposed, and is engaged therewith. That is, the second claw portion 35 is fitted into the opening portion 57 along the attaching direction of the reinforcing member 23 (see fig. 8). This can improve the workability in attaching the reinforcing member 23.

When the reinforcing member 23 is attached to the joint portion between the metal plate 21 and the handle member 22, the recesses 56 provided in the upper surface portion 52 of the reinforcing member 23 are positioned below the claws 34 of the handle member 22 (see fig. 5). The front surface 51 of the reinforcing member 23 supports the front surface 21a of the metal plate 21 from the rear surface side (see fig. 5). The rear portion 53 of the reinforcing member 23 supports the front side of the recess 31a of the handle member 22 (see fig. 5). Thus, in the formation region of the grip portion 31, the joint portion between the metal plate 21 and the grip member 22 is closed from the inside by the reinforcing member 23. Therefore, leakage of the foamed heat insulating material filled in the door interior and positional displacement of the metal plate 21 can be suppressed.

The same configuration as described above can be applied to the joint between the lower lid member 24 provided at the lower end of the vegetable compartment door 12a and the metal plate 21. Therefore, a reinforcing member that covers the engaging portion between the bent portion 41 and the claw portion (not shown) of the lower cover member 24 from the inside of the door may be provided at the joining portion between the metal plate 21 and the lower cover member 24.

In another embodiment, no reinforcing member may be provided at the joint between the metal plate 21 and the lower cover member 24.

(for pasting on the inclined plane part of the handle part)

Next, a more specific configuration of the inclined surface portion 32 of the handle member 22 and the attachment member 61 attached to the inclined surface portion 32 will be described. In fig. 9, a part (right side part) of the attaching member 61 is shown enlarged.

As shown in fig. 7, the inclined surface portion 32 of the handle member 22 is provided with a convex portion 71 along the outer periphery. The adhesive member 61 is attached to the region surrounded by the convex portion 71. In the present embodiment, as shown in fig. 8, the height of the convex portion 71 is larger (i.e., higher) than the thickness of the adhesive member 61. This makes it possible to make the attachment member 61 less likely to peel off from the inclined surface portion 32.

The adhesive member 61 is mainly composed of a print layer on the front surface, an adhesive layer on the back surface, and a base material layer located between the print layer and the adhesive layer. Various patterns are printed on the printing layer. Further, a gloss finish may be applied to the surface of the printed layer or a protective layer may be laminated thereon. The adhesive layer includes, for example, an adhesive tape or an adhesive. This makes it possible to easily attach the attachment member 61 to the surface of the inclined surface portion 32.

The base material layer forms most of the adhesive member 61. The thermal expansion coefficient of the joining member 61 is determined by the material of the base material layer. The material of the base layer is selected in consideration of the thermal expansion coefficient of the resin material (e.g., ABS, PP, PS, etc.) forming the handle member 22. That is, it is preferable to select a material of the base layer of the adhesive member 61 having a thermal expansion coefficient approximately equal to that of the handle member 22.

That is, the thermal expansion coefficient of the base material layer of the adhesive member 61 is in the range of 0.5 times to 10 times the thermal expansion coefficient of the resin material forming the handle member 22. Further, the thermal expansion coefficient of the base material layer of the adhesive member 61 is more preferably in the range of 0.5 times to 3 times the thermal expansion coefficient of the resin material forming the handle member 22. This can prevent wrinkles, cracks, and the like from being generated on the surface of the attachment member 61 attached to the inclined surface portion 32, and can maintain the aesthetic appearance of the surface of the attachment member 61.

As described above, the resin material forming the handle member 22 is, for example, ABS, PP (polypropylene), PS (polystyrene), or the like. In this case, the substrate layer of the attachment member 61 is preferably formed of, for example, PET (polyethylene terephthalate), PP, PS, PE (polyethylene), or the like.

The thermal expansion coefficients of the respective resin materials are as follows.

ABS：(6.0～13)×10 ^-5 /℃

PP：(5.8～10.2)×10 ^-5 /℃

PS：(6.0～8.0)×10 ^-5 /℃

PET：(6.5)×10 ^-5 /℃

PE：(11～20)×10 ^-5 /℃

In addition, in consideration of the difference in thermal expansion coefficient between the handle member 22 and the attachment member 61, the planar area of the attachment member 61 is preferably slightly smaller than the area of the inclined surface portion 32 to be attached.

As shown in fig. 2, the attachment member 61 has two large surface portions 62 and a linear portion 63 connecting the two large surface portions 62. The two large surface portions 62 are located at respective ends of the attachment member 61 in the longitudinal direction. Each large surface portion 62 is attached to a position corresponding to the inclined surface portion 32 of the handle member 22. The linear portion 63 has a smaller width in the vertical direction than the large surface portion 62, and extends from one end side of one large surface portion 62 toward one end side of the other large surface portion 62 in a borderline shape.

Here, as shown in fig. 9, an angle formed by one end side 62a of the large surface portion 62 and an end side 63a of the linear portion 63 continuing from the one end side 62a is represented by θ. The angle θ is preferably 90 degrees or more. When a foamed heat insulating material is formed inside the door of the refrigerator such as the vegetable compartment door 12a, the handle member 22 may be deformed due to the influence of thermal expansion or thermal contraction of the foamed heat insulating material. In the example of the present embodiment, the inclined surface portions 32 are disposed so as to be spaced from each other in the left-right direction, and the narrow width portions 33 extend so as to connect the inclined surface portions 32 on both the left and right sides, so that a difference in the amount of expansion or contraction of the foamed heat insulating material tends to occur at corner portions of the handle member 22 located at the boundary between the inclined surface portions 32 and the narrow width portions 33. Therefore, the deformation of the handle member 22 is easily concentrated on the corner portion. Therefore, by setting the angle θ of the corner portion to 90 degrees or more, the stress at the time of thermal expansion and contraction can be dispersed in the vertical direction, and the occurrence of local deformation in the corner portion of the handle member 22 can be suppressed.

Further, by making the shape of the attachment member 61 (the corner portion between the end edge 62a and the end edge 63 a) corresponding to this corner portion the same angle, the handle member 22 and the attachment member 61 can be seen integrally, and the appearance can be improved. Further, even when some deformation occurs in the corner portion of the handle member 22, stress can be dispersed in the vertical direction in the corner portion of the attachment member 61, and therefore, the attachment member 61 can be more reliably prevented from being wrinkled.

In the example shown in fig. 9, the corner portion formed by the edge 62a of the large surface portion 62 and the edge 63a of the linear portion 63 is formed in an R shape. This makes it possible to prevent the vicinity of a corner fold that may occur when the attachment member 61 is attached to the inclined surface portion 32, for example.

(construction of drawer type door except for vegetable room door)

In the present embodiment, the vegetable compartment door 12a is described as an example of the door of the refrigerator, but the door of the refrigerator of the present embodiment is not limited to the vegetable compartment door. The doors of the refrigerator may be, for example, an ice making chamber door 14a, a freezing chamber door 13a, a freezing chamber door 15a, and the like.

In addition, depending on the door, the arrangement position of the handle portion 31 may be different from the vegetable room door 12 a. For example, in the case of the refrigerator 1 of the present embodiment, the handle portion 31 of the ice making chamber door 14a is disposed with the handle portion 31 biased to the right of the upper end thereof.

Fig. 10 illustrates the external appearances of the ice-making chamber door 14a, the freezing chamber door 13a, and the freezing chamber door 15 a. Fig. 10 also shows a sticking member (sheet member) 61 that is stuck to the handle member 22 of each of the doors 13a, 14a, and 15 a. The attaching members 61 have shapes matching the shapes of the inclined surface portion 32 and the narrow width portion 33 provided in the handle member 22, similarly to the attaching members 61 attached to the vegetable compartment door 12 a.

(summary of the first embodiment)

As described above, the refrigerator 1 of the present embodiment includes doors such as the vegetable compartment door 12 a. The vegetable compartment door 12a includes a metal plate (front panel) 21 and a handle member 22. The metal plate 21 is disposed on the front surface of the door. The handle member 22 is attached to one end of the metal plate 21 in a state in which the one end can be visually confirmed. An attachment member (sheet member) 61 is attached to the front side of the door of the handle member 22. The thermal expansion coefficient of the adhesive member 61 is 0.5 times or more and 10 times or less the thermal expansion coefficient of the handle member 22. In the present embodiment, the handle member 22 has the inclined surface portion 32 positioned on the front side of the door, and the attachment member (sheet member) 61 is attached to the inclined surface portion 32 of the handle member 22.

According to the above configuration, the handle member 22 is attached to one end edge (specifically, the bent portion 41) above the metal plate 21, whereby the upper end portion of the metal plate 21 forming the front surface portion of the vegetable compartment door 12a can be exposed when the refrigerator 1 is viewed from the front. In this way, by adopting a configuration in which the upper end portion of the metal plate 21 is not covered with a lid member such as the handle member 22, for example, the front surface side of the refrigerator 1 can be more aesthetically pleasing.

Further, in the refrigerator 1 of the present embodiment, the attachment member 61 is attached to the inclined surface portion 32 of the handle member 22. The thermal expansion coefficient of the adhesive member 61 is 0.5 times or more and 10 times or less the thermal expansion coefficient of the handle member 22. This can suppress the occurrence of wrinkles, cracks, and the like on the surface of the attachment member 61 attached to the inclined surface portion 32 due to the difference in thermal expansion coefficient between the handle member 22 and the attachment member 61. Therefore, the refrigerator can maintain the beauty of the surface of the adhesive member 61 and can further improve the beauty of the handle portion having the inclined surface on the front surface.

In the configuration in which the upper end portion of the metal plate 21 is exposed, it is preferable to suppress the occurrence of floating of the surface of the end portion of the metal plate, which may occur when a foaming heat insulator or the like is injected into the door. In the present embodiment, the claw portion 34 provided in the handle member 22 is locked in the hole 42 provided in the bent portion 41 of the metal plate 21 at the joint portion between the metal plate 21 and the handle member 22, and therefore the metal plate 21 can be restricted from moving in the front-rear direction with respect to the handle member 22. This reduces the possibility of floating or unevenness being formed on the surface of the upper end of the metal plate 21.

< second embodiment >

Next, a second embodiment of the present invention will be explained. In the second embodiment, the configuration of the handle portion of each door of the refrigerator is different from that of the first embodiment. The same configuration as that of the first embodiment can be adopted for other configurations. Hereinafter, the freezing compartment door 13a provided in the refrigerator 1 of the present embodiment will be described as an example, but the present configuration can be applied to other doors such as the vegetable compartment door 12a, the ice-making compartment door 14a, and the freezing compartment door 15 a.

Fig. 11 shows an appearance of the freezer door 13a as viewed from the front side. In fig. 11, the pasting parts 161 (specifically, the right pasting part 161a and the left pasting part 161b) of the handle part 22 pasted to the freezing compartment door 13a are also illustrated.

In the refrigerator 1 of the present embodiment, the attaching member 161 is divided into two. Of the sticking members 161, the right sticking member 161a is stuck to the right inclined surface portion 132a and a part of the right side of the narrow portion 33 in the front view. Of the bonding members 161, the right bonding member 161b is bonded to the left inclined surface portion 132b and a part of the left side of the narrow portion 33 when viewed from the front.

In the narrow portion 33 of the handle member 22, a gap 133a is provided between the region where the right-side attachment member 161a is attached and the region where the left-side attachment member 161b is attached. When the joining members 161a and 161b thermally expand, the gap 133a can serve as a preliminary region for disposing the end portions of the joining members 161a and 161 b.

In the present embodiment, the gap 133a is provided not at the center of the narrow portion 33 in the left-right direction but slightly to the left. Thereby, the boundary position (refer to fig. 1) of the ice making chamber door 14a and the freezing chamber door 15a positioned at the upper layer of the freezing chamber door 13a and the position of the gap 133a can be aligned, and a sense of unity of the design of the refrigerator 1 can be felt.

< third embodiment >

Next, a third embodiment of the present invention will be explained. In the third embodiment, the configuration of the handle portion of each door of the refrigerator is different from that of the first embodiment. The same configuration as that of the first embodiment can be adopted for other configurations. Hereinafter, the freezing compartment door 13a provided in the refrigerator 1 of the present embodiment will be described as an example, but the present configuration can be applied to other doors such as the vegetable compartment door 12a, the ice-making compartment door 14a, and the freezing compartment door 15 a.

Fig. 12 shows an appearance of the freezer door 13a as viewed from the front side. In fig. 12, an adhering part 261 to which the handle part 22 of the freezing compartment door 13a is adhered is also illustrated.

The handle member 22 of the freezing chamber door 13a of the present embodiment is provided with a protrusion 233a for positioning, which serves as a mark when the attachment member 261 is attached to the inclined surface portion 32 and the narrow width portion 33. The projection 233a is provided on the lower side of the narrow portion 33. The attachment member 261 has a notch 264 formed at a position corresponding to the projection 233 a. Thus, when the attachment member 261 is attached to the inclined surface portion 32 and the narrow portion 33, the attachment member 261 can be easily positioned.

The projection 233a is not provided at the center of the narrow portion 33 in the left-right direction, but is provided slightly to the left. Thus, the boundary position (refer to fig. 1) of the ice making chamber door 14a and the freezing chamber door 15a positioned at the upper layer of the freezing chamber door 13a can be aligned with the position of the protrusion 233a, and a sense of unity in design of the refrigerator 1 can be felt.

< fourth embodiment >

Next, a fourth embodiment of the present invention will be explained. In the fourth embodiment, the configuration of the handle portion of each door of the refrigerator is different from that of the first embodiment. The same configuration as that of the first embodiment can be adopted for other configurations. Hereinafter, the freezing chamber door 13a provided in the refrigerator 1 of the present embodiment will be described as an example, but the present configuration can be applied to other doors such as the vegetable chamber door 12a, the ice making chamber door 14a, and the freezing chamber door 15 a.

Fig. 13 shows an appearance viewed from the front side of the freezing compartment door 13 a. Fig. 13 also illustrates the pasting part 361 attached to the handle part 22 of the freezing compartment door 13 a.

The handle member 22 of the freezing chamber door 13a of the present embodiment is provided with a projection 333a for positioning which serves as a mark when the attachment member 361 is attached to the inclined surface portion 32 and the narrow width portion 33. The projection 333a is provided on the lower side of the narrow portion 33. Further, a notch 364 is formed in the attachment member 361 at a position corresponding to the projection 333 a. This facilitates positioning of the attachment member 361 when attaching the attachment member 361 to the inclined surface portion 32 and the narrow portion 33.

In the present embodiment, the projection 333a is provided at a substantially central position in the left-right direction of the narrow portion 33. The notch 364 provided in the attachment member 361 is provided at a substantially central position in the longitudinal direction of the attachment member 361, in accordance with the position of the projection 333 a.
