In the present embodiment, the handle member is attached to the handle-side bent portion 21d of the metal plate 21. The handle member is formed by molding a resin material such as ABS, PP, PS, or the like, as in the case of the cover member 22 or the like. The handle member has a handle portion for allowing a user to catch the handle when opening the door.

The back member 25 is formed by molding a resin material such as ABS, PP, or PS. The rear member 25 is attached to cover the rear surface portion of the refrigerating chamber door 11 a. Thereby, the outer shape of the door is formed.

The heat insulating material is provided inside the door outer casing formed by combining the metal plate 21, the cover member 22, the pressing member 23, the lower cover member 24, the handle member, the back surface member 25, and the like. The heat insulating material is formed by filling a foamed heat insulating material such as foamed polyurethane into the door outer body.

(Structure of joint part of Metal plate and cover Member)

Next, a more detailed structure of the joint portion between the metal plate 21 and the lid member 22 will be described. Fig. 7 shows the structure of the inner side (the side in contact with the heat insulating material) of the cover member 22. Fig. 8 shows an external appearance of the pressing member 23 attached to a joint portion of the metal plate 21 and the lid member 22.

As described above, the metal plate 21 mainly includes the front surface portion 21a, the side surface portion 21b, the upper bent portion 41a, the lower bent portion 41b, the rear surface bent portion 21c, the handle bent portion 21d, and the like.

At least one concave portion 42 obtained by cutting out a part of the metal plate 21 is formed in the upper bent portion 41a and the lower bent portion 41 b. In the example shown in fig. 4, two recesses 42 are formed in the upper end bent portion 41a, and two recesses 42 are formed in the lower end bent portion 41 b.

Further, a notch 45 (see fig. 4) formed by cutting out a part of the metal plate 21 is provided at an upper end of the rear-side folded portion 21 c. The notch 45 is provided at a position corresponding to the locking portion 33 of the cover member 22, and is configured as an engagement portion that engages with the cover member 22.

The outer shape of the cover member 22 is mainly formed by an upper surface portion 22a, a front portion 22b, left and right side portions 22c, and a rear surface portion 22 d. The names of the respective parts of the lid member 22 are defined based on the positions of the lid member 22 in the state of being attached to the refrigerating chamber door 11 a. The cover member 22 has a hinge portion 31 near one of the left and right side portions 22 c. In the case of the refrigerating compartment door 11a, the hinge portion 31 is provided in the vicinity of the left side portion 22c when viewed from the front.

In the present embodiment, the cover member 22 includes the locking portion 33 including the engaging portion corresponding to the metal plate 21. The locking portion 33 is provided on the rear surface side of the refrigerating chamber door 11a (i.e., at a position corresponding to the rear surface side bent portion 21c of the metal plate 21) (see fig. 4 and the like). The locking portion 33 is provided with a rib (fitting portion) 34 (see fig. 7), and the rib (fitting portion) 34 is fitted into the notch portion 45 provided in the back-side bent portion 21c of the metal plate 21.

The side portion 22c of the cover member 22 is provided with an opening 36 (see fig. 5). The second claw portion 54 of the pressing member 23 is fitted into the opening portion 36.

The pressing member 23 includes a side portion 51, a front portion 52, a rear portion 53, and the like (see fig. 8). Names of the respective portions of the pressing members 23 are defined based on positions of the pressing members 23 in a state of being mounted on the refrigerating compartment door 11 a. In addition, the pressing member 23 is provided with a second claw portion 54. The second claw portion 54 is fitted into the opening portion 36 provided in the side portion 22c of the cover member 22.

The side portion 51 and the front portion 52 of the pressing member 23 are disposed around the hinge portion 31 (see fig. 3). This can reinforce the periphery of the hinge portion 31 of the refrigerating chamber door 11 a.

The rear portion 53 of the pressing member 23 is disposed at a position corresponding to the locking portion 33 located at the end of the rear surface portion 22d of the cover member 22. The rear portion 53 of the holding member 23 is provided so as to cover the locking portion of the metal plate 21 and the cover member 22 from the inside of the door (see fig. 3 and the like). By providing such a pressing member 23, a gap formed between the metal plate 21 and the lid member 22 can be narrowed or closed. This can suppress leakage of the foamed heat insulating material filled inside the door. Further, when the metal plate 21 and the cover member 22 are assembled, the metal plate 21 can be prevented from being displaced and detached.

When the cover member 22 is attached to the metal plate 21, the front portion of the upper end bent portion 41a of the metal plate 21 is inserted into the fitting groove provided in the front portion 22b of the cover member 22 (see fig. 5). Then, the claw portion (not shown) of the cover member 22 is engaged with the recessed portion 42 provided in the upper end bent portion 41 a.

Next, the rib 34 provided in the locking portion 33 of the cover member 22 is fitted into the notch 45 provided in the back-side bent portion 21c of the metal plate 21 from above. At this time, the lower surface of the upper surface portion 22a of the cover member 22 abuts against the upper surface of the lateral portion of the upper end bent portion 41a of the metal plate 21. Thereby, the side portion 22c of the cover member 22 is covered with the side portion 21b of the metal plate 21.

In this way, in the metal plate 21, the locking portion corresponding to the cover member 22 is provided at the back-side bent portion 21c apart from the front surface portion 21a of the metal plate 21, so that the operability in attaching the cover member 22 can be improved. Further, the locking portions of the metal plate 21 and the cover member 22 are configured by the notch 45 provided in the rear-side bent portion 21c and the rib 34 of the cover member 22, so that the movement of the cover member 22 in the left-right direction with respect to the metal plate 21 is restricted, and the positional displacement and the detachment at the time of assembling the refrigerating chamber door 11a can be suppressed.

Thus, even if the fitting groove is not provided in the side portion 22c of the cover member 22, the side portion of the upper end bent portion 41a of the metal plate 21 can be aligned with the side portion 22c of the cover member 22. Therefore, when the fitting groove is provided in both the front portion 22b and the side portion 22c of the cover member 22, the work step of fitting the side portion 21b of the metal plate 21 into the fitting groove of the cover member 22 while expanding the side portion is not required. Therefore, deformation of the metal plate 21 when the cover member 22 is attached can be prevented, and the workability when attaching can be improved.

After the cover member 22 is attached to the metal plate 21, the pressing member 23 is attached.

The pressing member 23 is attached to the lid member 22 from the lower side of the lid member 22 (see fig. 4 and 6). At this time, the second claw portion 54 of the pressing member 23 moves from the lower side of the opening portion 36 of the cover member 22 to the arrangement position of the opening portion 36 and engages therewith. That is, the second claw portions 54 are fitted into the opening portions 36 along the mounting direction of the pressing member 23. This can improve the operability when the pressing member 23 is attached.

When the pressing member 23 is attached to the joint portion between the metal plate 21 and the cover member 22, the hinge portion 31 is supported laterally by the side portion 51 and the front portion 52 of the pressing member 23 (see fig. 3). This can improve the strength around the hinge portion 31.

The rear portion 53 of the holding member 23 covers the locking portion of the metal plate 21 and the cover member 22 from the inside of the door (see fig. 3). Thereby, the joint portion between the metal plate 21 and the lid member 22 is in a state in which the pressed member 23 is closed from the inside of the door. Therefore, it is possible to suppress leakage of the foamed heat insulating material filled in the door interior, or to suppress positional displacement of the metal plate 21.

The same configuration as described above can be applied to the joint portion between the lower cover member 24 provided at the lower end portion of the refrigerating chamber door 11a and the metal plate 21. Therefore, the pressing member may be provided also at the joint portion between the metal plate 21 and the lower lid member 24.

In another embodiment, the pressing member may not be provided for joining the metal plate 21 and the lower lid member 24.

(summary of the first embodiment)

As described above, the refrigerator 1 according to the present embodiment includes the refrigerating chamber doors 11a and 11b that are opened and closed in the refrigerating chamber 11.

Further, the locking portions of the metal plate 21 and the cover member 22 are configured by the notch 45 provided in the rear-side bent portion 21c and the rib 34 of the cover member 22, so that the movement of the cover member 22 in the left-right direction with respect to the metal plate 21 is restricted, and positional deviation and detachment at the time of assembly of the refrigerating chamber door 11a can be suppressed.

In this way, in the refrigerating compartment door 11a of the present embodiment, the bent portion 21c on the back side of the metal plate 21 is engaged with the cover member 22, so that the movement of the metal plate 21 in the left-right direction can be restricted, the deformation of the metal plate 21 when the cover member 22 is attached can be prevented, and the workability in attachment can be improved.

Further, by locking the cover member 22 to the back surface side of the metal plate 21, the locking portion 33 of the cover member 22 can be provided at a position not visible from the front. Therefore, the appearance of the front side of the refrigerator 1 can be improved.

In the present embodiment, the metal plate 21 and the lid member 22 are engaged with each other by providing the notch portion 45 on the metal plate 21 side and providing the protrusion-like structure (for example, the rib 34) that fits into the notch portion 45 on the lid member 22 side. However, in another embodiment, a convex portion may be provided at the back-side bent portion 21c of the metal plate 21, and a concave portion, a hole, or the like may be provided so that the convex portion fits into the locking portion 33 of the cover member 22.

The locking portion 33 is provided with a rib (fitting portion) 34, and the rib 34 is fitted into the notch portion 45 provided in the back-side folded portion 21c of the metal plate 121.

The lid member 122 according to the present embodiment is different from the lid member 22 described in the first embodiment in that a claw portion 135 is provided in the vicinity of the side portion 22c on the side where the hinge portion 31 is provided. In a state where the cover member 122 is attached to the metal plate 121, the claw portion 135 is fitted into the hole 146 provided in the metal plate 121.

The pressing member 123 has the side portion 51, the front portion 52, the rear portion 53, and the like as in the first embodiment. The pressing member 123 of the present embodiment has a concave portion 155 (see fig. 9) as a configuration different from the pressing member 23 described in the first embodiment. The concave portion 155 is provided on the rear side of the upper surface of the side portion 51 (i.e., at a position corresponding to the claw portion 135 of the cover member 122). In a state where the pressing member 123 is attached to the joint portion between the metal plate 121 and the lid member 122, the recess 155 is positioned below the claw portion 135 and the hole 146.

When the cover member 122 is attached to the metal plate 121, the front portion of the upper end bent portion 41a of the metal plate 121 is inserted into the fitting groove provided in the front portion 22b of the cover member 122. Then, the claw portion (not shown) of the cover member 22 is engaged with the concave portion 42 provided in the upper end bent portion 41 a.

The claw portion 135 of the cover member 122 is fitted into the hole 146 of the metal plate 121 while the upper end bent portion 41c of the metal plate 121 is aligned with the side portion 22c of the cover member 122. Then, the rib 34 provided in the locking portion 33 of the cover member 122 is fitted in the notch 45 provided in the back-side folded portion 21c of the metal plate 121.

As described above, the refrigerating compartment door 111b according to the present embodiment is provided with the locking portion that locks with the lid member 122, in addition to the back-side bent portion 21c of the metal plate 121, at the upper-end bent portion 41c that continues to the side surface portion 21b of the metal plate 121. This can more reliably restrict movement of the lid member 122 in the left-right direction with respect to the metal plate 121, and can suppress positional displacement and detachment at the time of assembly of the refrigerating compartment door 11 a.

Further, the lid member 122 is locked at two positions, i.e., the back-side bent portion 21c and the upper-end bent portion 41c of the metal plate 121, so that the gap between the lid member 122 and the metal plate 121 can be reduced. This makes it possible to provide a structure in which the foamed heat insulating material filled in the door is less likely to leak. Therefore, the pressing member 123 may not be provided in the refrigerating compartment door 111b according to the present embodiment.

In the refrigerating compartment door 111b of the present embodiment, the lid member 122 is attached to the upper bent portion 41a of the metal plate 121, so that when the refrigerator 1 is viewed from the front, the upper end portion of the metal plate forming the front face portion and the side face portion of the door can be exposed from the front face to the side face. In this way, the top end of the metal plate 121 is not covered with the cover member 122, for example, so that the front surface side of the refrigerator 1 can be more aesthetically pleasing.

< modification example >

Next, a modified example of the present invention will be explained. In the modification, the structure of the joint portion between the metal plate and the lid member is different from that of the above-described embodiment. The same configuration as that of the first and second embodiments can be applied to the other configurations.

Hereinafter, the refrigerating chamber door 211b of the refrigerator 1 according to the modified example will be described as an example. The refrigerating chamber door 211b is located on the right side of the refrigerating chamber 11 as viewed from the front. A hinge portion 31 is provided at an end portion of the right side of the refrigerating chamber door 211 b. The refrigerator 1 according to the present embodiment includes another refrigerating chamber door (not shown). The same structure as the refrigerating chamber door 211b can be applied except that the refrigerating chamber door has a bilaterally symmetrical structure with the refrigerating chamber door 211 b.

Fig. 11 illustrates an exploded state of the metal plate 221, the cover member 222, and the pressing member 223 of the structure refrigerating chamber door 111 b. Fig. 12 shows the appearance of the inside (the side in contact with the heat insulating material) of the cover member 222. Fig. 13 shows an appearance of the pressing member 223.

The refrigerating chamber door 211b mainly includes a metal plate 221, a cover member 222, a pressing member 223, a lower cover member 24 (not shown in fig. 11), a handle member (not shown), a back surface member 25 (not shown in fig. 11), a heat insulating material (not shown), and the like. The lower cover member 24, the handle member, the back surface member 25, and the heat insulating material may have the same structure as in the first embodiment.

The metal plate 221 can have substantially the same structure as the metal plates 21 and 121 and the like described in the above embodiments. However, the metal plate 221 is not provided with the notch 45 at the upper end of the back-side folded portion 21 c. Further, similarly to the metal plate 121, the hole 146 is provided in the upper end bent portion 41c of the metal plate 221.

The lid member 222 can be configured substantially the same as the lid members 22 and 122 described in the above embodiments. However, in the cover member 222, the locking portion 33 located on the rear surface side of the refrigerating compartment door 211b is not provided with the rib (fitting portion) 34. Further, similarly to the cover member 122, a claw portion 135 is provided in the vicinity of the side portion 22c of the cover member 222. The claw portion 135 is fitted into a hole 146 provided in the metal plate 221.

The lid member 223 can be configured substantially the same as the lid members 23 and 123 and the like described in the above embodiments. Further, similarly to the pressing member 123, a recess 155 is provided on the rear side of the upper surface of the front portion 52 of the pressing member 223 (i.e., at a position corresponding to the claw portion 135 of the lid member 222). In a state where the pressing member 223 is attached to the joint portion between the metal plate 221 and the cover member 222, the recess 155 is positioned below the claw portion 135 and the hole 146.

As described above, in the refrigerating chamber door 211b of the modification, the claw portion 135 located at the side portion 22c of the cover member 222 is fitted into the hole 146 provided in the upper end bent portion 41c continuous with the side surface portion 21b of the metal plate 221, thereby locking the metal plate 221 and the cover member 222. That is, as in the above-described embodiment, the metal plate 221 and the cover member 222 are not locked to the rear surface side of the door, but locked to the side surface side of the door. This can more reliably restrict movement of the cover member 222 in the left-right direction with respect to the metal plate 221, and can suppress positional displacement and detachment at the time of assembly of the refrigerating chamber door 211 b.

In addition, as in the above-described embodiment, after the cover member 222 is attached to the metal plate 221, the pressing member 223 is attached. Since the pressing member 223 is attached, the joint portion between the metal plate 221 and the cover member 222 is closed from the inside of the door by the pressing member 223. Therefore, it is possible to suppress leakage of the foamed heat insulating material filled in the door interior, and to suppress positional displacement of the metal plate 221.

In the refrigerating chamber door 211b of the present embodiment, the cover member 222 is attached to the upper bent portion 41a of the metal plate 221, and thus, when the refrigerator 1 is viewed from the front, the upper end portion of the metal plate forming the front surface portion and the side surface portion of the door can be exposed from the front surface to the side surface. In this way, the top end of the metal plate 221 is not covered with the cover 222, for example, so that the front surface of the refrigerator 1 can be more aesthetically pleasing.
