Figures 5 and 6 are, for example, from 16066.
This is the conventional refrigerator door shown in the publication. In this figure, 1 indicates the door body, 2 is a rectangular door frame with a substantially U-shaped cross section, 3 is a door front plate that is fitted into the front part of the inside of the door frame 2, and 4 is a heat insulating material. Door frame 2 and door front plate 3 are made of hard urethane foam.
The door frame 2, the door front plate 3, and the heat insulating material 4 constitute the door body 1. Reference numeral 5 denotes a door inner plate attached to the back side of the door frame 2.

(V-cut processing). At the same time, cut surfaces are formed at one end 2a and the other end 2b, respectively, which are inclined at 45 degrees toward the center. Next, this is bent to form a rectangular frame and a door front plate 3 is fitted thereinto to form a box with the door front plate 3 and the door frame 2, and a hard urethane foam 4 is foamed inside the box. It is something.

In the conventional door body as described above, one end 2 of the door frame 2
Since the seam 7 where a and the other end 2b come into contact becomes a sharp edge, in this state there is a risk of injury to the user due to contact. Therefore, after the foaming of the heat insulating material 4 is completed, the sharp edge portions are filed and the seam portions 7 are chamfered. However, this requires a lot of man-hours, and depending on variations in sanding, the sharp edges may not be completely removed, and there are also problems with the appearance.

FIG. 1 shows the state of a refrigerator door according to an embodiment of the present invention before the door frame is bent. As with the conventional door frame 8, 90° V-cut portions 9 are formed at three bent portions corresponding to the corners of the door front plate, and one end 8
A and the other end 8b each form a cut portion inclined at 45° toward the center. 10a and 10b are provided at the tips of one end 8a and the other end 8b as shown in FIG.
The slopes are formed so that they are inclined at an angle of 45 degrees.
This processing is performed simultaneously with the processing of the V-cut portion 9, one end 8a, and the other end 8b. The door frame 8 constructed in this way is bent into a rectangular frame as shown in FIG. 3, and the door front plate 3 is fitted inside the frame. Then, hard urethane foam is foamed and adhered to the space formed by the door front plate 3 and the door frame 8 to form a door body. Also, at this time, the seam 7 has one end 8a as shown in FIG.
The slope portions 10a and 10b of the other end 8b create a state similar to that of being chamfered, and no sharp edges occur.

As explained above, this invention provides sloped parts at the tips of one end and the other end of the door frame, so there is no need for chamfering by sanding, etc., and manufacturing costs can be lowered. Since there is no chamfering, the surface has a uniform chamfered state, which has the effect of improving the appearance.
