The gap in the up-down direction between the tip of the in-groove protrusion 70 and the outer wall 61a is set to be equal to or greater than the thickness of the upper mounting surface 54. In this embodiment, multiple in-groove protrusions 70 are provided with gaps in the left-right direction. As shown in Figures 6 and 10, the front side of the in-groove protrusion 70 is provided with an inclined portion 70a that slopes toward the inner wall 69 as it extends forward.
[0046] The locking portion 71 is a claw-shaped protrusion that protrudes from the outer wall 61a toward the inner wall 69 and into the front groove portion 62. The locking portion 71 is provided at a position corresponding to the locked portion 57 provided on the upper mounting surface 54 of the door panel 50, and when the upper end member 60 is attached to the door panel 50, the locking portion 71 is inserted into and locked with the locked portion 57 provided on the upper mounting surface 54. In addition, an inclined portion 71a is provided on the front side of the locking portion 71, which is inclined so as to approach the outer wall 61a as it extends forward. A through-hole 69a that penetrates the inner wall 69 is provided at a position on the inner wall 69 that is vertically opposite the locking portion 71.
[0047] The horizontal grooves 63 are grooves that open forward and downward and are provided on both the left and right end portions of the upper end member 60. The front ends of the horizontal grooves 63 are connected to the left and right ends of the front groove 62. When the upper end member 60 is attached to the door panel material 50, the upper ends of the side surfaces 52 of the door panel material 50 are accommodated in the horizontal grooves 63.
[0048] The rear wall 65 is a flat projection that projects inward in the door vertical direction and extends left and right from the rear end of the outer surface portion 61. The rear wall 65 comes into contact with the surface of the inner door panel 100 on the door inner side.
[0049] (6) Lower end member 80 The lower end member 80 is made of a molded synthetic resin and is joined to the lower end of the door surface material 50 and the door inner panel 100 to form the surface of the lower end of the door 40.
[0050] As shown in FIGS. 3 to 5 and 11, the lower end member 80, like the upper end member 60, comprises an outer surface portion 81, a front groove portion 82, left and right lateral groove portions 83, and a rear wall 85.
[0051] The outer surface portion 81 is disposed on the outer side of the door panel 50 in the vertical direction of the door, and is a portion that constitutes the exterior side of the door 40. As shown in Figures 4 and 9, one of the left and right ends of the outer surface portion 81 is provided with a shaft storage recess 87 that is recessed inward in the vertical direction of the door. The bottom of the shaft storage recess 87 is further provided with a bearing portion 86 that is recessed inward in the vertical direction of the door, and a recess 99 into which the anti-rotation shaft of the door closing device 18 is inserted. In addition, the other left and right end of the outer surface portion 81 is formed with a recess 88 that is recessed inward in the vertical direction of the door and functions as a handle for the door 40.
[0052] Similar to the front groove 62 provided in the lower end member 80, the front groove 82 is a groove that opens forward and is formed between an outer wall 81a that is the front end of the outer surface portion 81 and a flat inner wall 89 that extends in the left-right direction and is provided at an interval on the inside of the door in the vertical direction from the outer wall 81a. The front groove 82 is provided across the entire left-right direction of the lower end member 80, and accommodates the lower mounting surface 55 of the door face material 50.
[0053] Within the front groove portion 82, there is provided a groove protrusion 90 that protrudes into the front groove portion 62 from the inner wall 69 toward the outer wall 61a, and a locking portion 91 that protrudes into the front groove portion 62 from the outer wall 61a toward the inner wall 69.
[0054] The tip of the in-groove protrusion 90 faces the outer wall 81a with a gap therebetween in the up-down direction. The gap in the up-down direction between the tip of the in-groove protrusion 90 and the outer wall 81a is set to be equal to or greater than the thickness of the lower mounting surface 55. In this embodiment, multiple in-groove protrusions 90 are provided with gaps in the left-right direction. As shown in Figure 11, the front side of the in-groove protrusion 90 is provided with an inclined portion 90a that slopes toward the inner wall 89 as it extends forward.
[0055] The locking portion 91 is provided at a position corresponding to the locked portion 58 provided on the lower mounting surface 55 of the door panel material 50, and when the lower end member 80 is attached to the door panel material 50, the locking portion 91 is inserted into the locked portion 58 provided on the lower mounting surface 55. In addition, an inclined portion 91a is provided on the front side of the locking portion 91, which is inclined so as to approach the outer wall 81a as it goes forward. A through hole 69a that penetrates the inner wall 69 is provided in the inner wall 89 at a position that is vertically opposite to the locking portion 91.
[0056] The horizontal grooves 83 are grooves that open to the sides and are provided on both the left and right end portions of the lower end member 80. The front ends of the horizontal grooves 83 are connected to the left and right ends of the front groove 82. When the lower end member 80 is attached to the door panel material 50, the horizontal mounting surface 56 of the door panel material 50 is accommodated in the horizontal grooves 83.
[0057] The rear wall 85 is a flat projection that projects inward in the door vertical direction and extends left and right from the rear end of the outer surface portion 81. The rear wall 85 comes into contact with the surface of the door inner panel 100 on the door inner side.
[0058] (7) Manufacturing method of door 40 Next, a description will be given of a method for manufacturing the above-mentioned door 40. In the manufacturing process of the door 40, first, an operator assembles the upper end member 60, the lower end member 80, and the door panel 50.
[0059] Specifically, the worker slides the upper end member 60 forward at the upper end of the door panel material 50, inserting the upper mounting surface 54 of the door panel material 50 into the front groove portion 62 and inserting the lateral mounting surface 56 of the door panel material 50 into the lateral groove portion 63.
[0060] The upper mounting surface 54 inserted into the front groove portion 62 is guided by the inclined portion 70a of the groove protrusion 70 and inserted between the groove protrusion 70 and the outer wall 61a. At this time, the wide region 54a of the upper mounting surface 54 is guided by the inclined portion 71a of the locking portion 71 and inserted between the groove protrusion 70 and the outer wall 61a, and the locking portion 71 is inserted into the locked portion 57 provided on the wide region 54a.
[0061] The worker also slides the lower end member 80 forward at the lower end of the door panel material 50, inserting the lower mounting surface 55 of the door panel material 50 into the front groove portion 82 and inserting the lateral mounting surface 56 of the door panel material 50 into the lateral groove portion 83.
[0062] The lower mounting surface 55 inserted into the front groove portion 82 is guided by the inclined portion 90a of the groove protrusion 90 and inserted between the groove protrusion 90 and the outer wall 81a. At this time, the wide region 55a of the lower mounting surface 55 is guided by the inclined portion 91a of the locking portion 91 and inserted between the groove protrusion 90 and the outer wall 81a, and the locking portion 91 is inserted into the locked portion 58 provided on the wide region 55a.
[0063] When the upper end member 60 and the lower end member 80 are attached to the door panel 50, the door 40 is in an assembled state, and the door panel 50 and the end members 60, 80 form a space with an open back surface.
[0064] Once the door 40 is in the assembled state in this way, an operator injects a fluid foaming resin concentrate such as urethane foam into the interior space of the door 40 through the opening on the back, and then closes the back of the door 40 with the door inner panel 100. The foaming resin concentrate expands as it foams and flows through the interior space of the door 40, and after filling the interior space of the door 40, it solidifies and the door 40 is completed.
[0065] The worker manufactures the other doors using the same process as that for refrigerator compartment door 40. Then, the worker attaches each completed door and various devices to refrigerator body 11 to complete refrigerator 10.
[0066] (8) Effects In this embodiment, locking portions 71, 91 are provided in the front grooves 62, 82 of the end members 60, 80, and when the mounting surfaces 54, 55 of the door face material 50 are inserted into the front grooves 62, 82, the locking portions 71, 91 are inserted into the locked portions 57, 58 provided on the mounting surfaces 54, 55 of the door face material 50. The worker can easily feel a sense of resistance when the locking portions 71, 91 are inserted into the locked portions 57, 58, and can easily determine that the mounting surfaces 54, 55 are inserted into the predetermined positions in the front grooves 62, 82. Therefore, the door face material 50 can be attached to the end members 60, 80 with reduced distortion.
[0067] In particular, when the mounting surfaces 54, 55 are inclined outward in the vertical direction of the door as they move away from the front surface 51 of the door face material 50, the tips of the wide regions 54a, 55a of the mounting surfaces 54, 55 elastically deform so as to incline inward in the vertical direction of the door until the locking portions 71, 91 are inserted into the locked portions 57, 58. Thereafter, when the locking portions 71, 91 are inserted into the locked portions 57, 58, the deformation in the wide regions 54a, 55a of the mounting surfaces 54, 55 is released and the mounting surfaces 54, 55 return to their original shape. This makes it easier for the worker to feel the feedback when the locking portion 71 is inserted into the locked portion 57, and allows the mounting surfaces 54, 55 to be inserted into the predetermined positions in the front grooves 62, 82.
[0068] When the locking portions 71, 91 are provided on the outer walls 61a, 81a as in this embodiment, the locking portions 71, 91 protruding into the front groove portions 62, 82 can be molded integrally with other parts of the end members 60, 80 without affecting the appearance of the door 40.
[0069] When the locked portions 57 are provided in the wide regions 54a of the mounting surface 54 as in this embodiment, the locked portions 57 can be provided while ensuring the strength of the mounting surface 54, and by providing narrow regions 54b that protrude less than the wide regions 54a in locations where the locked portions 57 are not provided, it is possible to reduce distortion that occurs in the front surface 51 of the door panel material 50 due to the bending process of the mounting surface 54. Furthermore, if the locked portions 57 are provided in the center part in the front-to-rear direction of the wide regions 54a, it is easy to ensure the strength around the locked portions 57.
[0070] Similarly, when the locked portions 58 are provided in the wide region 55a of the mounting surface 55, the locked portions 58 can be provided while ensuring the strength of the mounting surface 55, and by providing narrow regions 55b that protrude less than the wide region 55a in locations where the locked portions 58 are not provided, it is possible to suppress distortion that occurs in the front surface 51 of the door panel material 50 due to the bending process of the mounting surface 55. Furthermore, if the locked portions 58 are provided in the center of the wide region 55a in the front-to-back direction, it is easy to ensure the strength around the locked portions 58. It is preferable to provide them in the center of the wide region 55a in the front-to-back direction.
[0071] As in this embodiment, when the engaging portions 57, 58 are provided in positions that avoid the recesses 66-68, 86-88, 99 that are recessed inward in the vertical direction of the door 40 in the width direction, it becomes easier to ensure the amount of protrusion of the mounting surfaces 54, 55 at the positions where the engaging portions 57, 58 are provided.
