[0032] (First embodiment)

[0033] Figure 1 It is a perspective view of the door frame 10 according to the first embodiment of the present invention. Figure 2 It is a top view of the dotted line portion of the door frame 10 according to the first embodiment of the present invention. Figure 3 It is a perspective view of the dotted line portion of the door frame 10 according to the first embodiment of the present invention when viewed from the back side of the refrigerator. Figure 4 It is a perspective view of the reinforcement member 16 provided in the side frame of the door frame 10 in the first embodiment of the present invention.

[0034] like Figures 1 to 3 As shown, door frame 10 is a rectangular frame when viewed from the front. A roughly V-shaped arcuate hole 11 is formed on one side (here, the right side) of the top of door frame 10 when viewed from above. Arcuate hole 11 includes a first arcuate hole 11a on one side and a second arcuate hole 11b on the other side. Arcuate hole 11 extends in an arc shape with a substantially uniform width w, except for its two ends, when viewed from above.

[0035] The arcuate groove portion 221 of the connection portion 22 of the fully built-in refrigerator door 20 described later can be inserted into the arcuate hole 11, and the arcuate protrusion portion 321 of the connection portion 32 of the non-fully built-in refrigerator door 30 described later can be engaged with the arcuate hole 11.

[0036] A first hole 12 is formed between the first arcuate hole 11a and the second arcuate hole 11b in the door frame 10. The cylindrical portion 222 of the connecting portion 22 of the fully built-in refrigerator door 20, described later, can be inserted into the first hole 12, and the columnar protrusion 323 of the connecting portion 32 of the non-fully built-in refrigerator door 30, described later, can be engaged with the first hole 12. Here, the first hole 12 has a circular shape when viewed from above.

[0037] On the door frame 10, a second hole 13 is formed approximately in the middle of the extension direction of the first arc-shaped hole 11a, and the diameter d of the second hole 13 is greater than the width w of the first arc-shaped hole 11a. Here, the approximately middle position of the second hole 13 is not limited to the exact middle position in the extension direction of the first arc-shaped hole 11a, but can also be a position close to one end or the other end of the first arc-shaped hole 11a. The cylindrical portion 322 (more specifically, the upper cylindrical portion 322u of the cylindrical portion 322) of the connecting portion 32 of the non-fully built-in refrigerator door 30 described later can be engaged with the second hole 13. Here, the second hole 13 is circular when viewed from above.

[0038] In a plan view, the connection between the first arcuate hole 11a and the second arcuate hole 11b (i.e., the top of the V) is located further inward than the first hole 12. That is, in a plan view, the top of the V-shaped arcuate hole 11 is located inward, and both ends of the arcuate hole 11 are located outward.

[0039] In this embodiment, when viewed from above, the length of the first arcuate hole 11a is shorter than the length of the second arcuate hole 11b in the extending direction of the arcuate hole 11. However, the present invention is not limited to this, and the length of the first arcuate hole 11a and the length of the second arcuate hole 11b may be the same, or the length of the first arcuate hole 11a may be longer than the length of the second arcuate hole 11b.

[0040] In addition, a first screw hole 14 and a second screw hole 15 are formed on the door frame 10 at a position further inward than the arc-shaped hole 11. Here, the arrangement direction of the first screw hole 14 and the second screw hole 15 is consistent with the width direction of the door frame 10. In the width direction of the door frame 10, the first hole 12 is located between the first screw hole 14 and the second screw hole 15. However, this is not limited to this, and the positions of the first screw hole 14 and the second screw hole 15 can also be appropriately changed, as long as the connection portion 22 of the fully built-in refrigerator door 20 described later and the connection portion 32 of the non-fully built-in refrigerator door 30 described later can be fixed to the door frame 10 using screws passing through the first screw hole 14 and the second screw hole 15.

[0041] In addition, reinforcement members for increasing the strength of the door frame 10 are provided on the upper side frame, the lower side frame, the left side frame, and the right side frame of the door frame 10 . Figure 3 、 4 The figure shows a reinforcement member 16 provided on the right side frame of the door frame 10 and extending in the up-down direction.

[0042] When the door frame 10 of the present embodiment is adopted, since the fully built-in refrigerator and the non-fully built-in refrigerator can share the door frame 10, it is only necessary to prepare a mold corresponding to the door frame 10, and there is no need to prepare molds corresponding to different types of door frames, which can reduce production costs.
