  When the transport handle 6 is attached to the opening 50 according to the above procedure, the pinching portion 64 provided on the rear side is formed so that the size of the convex projecting outward is slightly smaller than that of the pinching portion 63 provided on the front side It is desirable to do. This is because the transport handle 6 can be easily attached to the opening 50 by forming the rear-side holding portion 64 to be attached later to a smaller size. On the other hand, when carrying the refrigerator 100, the force of the carrier is applied to the sandwiching portion 63 provided on the front side in the refrigerator 100 which is turned down so that each door faces upward. Therefore, it is desirable that the front side pinching portion 63 be configured to be able to hold and hold the opening edge of the opening 50 firmly by enlarging the dimension of the convex shape that protrudes outward.

  Further, although not shown in detail, the refrigerator 100 according to the present embodiment is the flange portion 61 a of the flange portions 61 provided on the carrying handle 6 that faces the flange portion 61 a facing in the depth direction Y of the refrigerator main body 1. Alternatively, sandwiching portions 63 and 64 may be formed to sandwich the opening edge of the opening 50 of the bottom plate 5 together with the flange 61a. In this case, the rib 51 is formed at the opening edge of the width direction X of the refrigerator body 1 among the opening edges of the opening 50 of the bottom plate 5 from the opening edge toward the inside of the refrigerator. Then, in the flange portion 61 b of the flange portion 61 of the carrying handle 6, the recessed storage portion 62 for storing the rib 51 provided on the bottom plate 5 is formed in the flange portion 61 b opposed along the width direction X of the refrigerator 100. However, when carrying the refrigerator 100, the force of the carrier acts in the vertical direction (the depth direction Y of the refrigerator 100) in the refrigerator in which each door is turned up, so the opening edge of the opening 50 is firmly fixed. It is desirable to form in the flange part 61b which opposes along the width direction X of the refrigerator 100 for the clamping parts 63 and 64 which can be clamped and held.

  In the case where it is difficult to transport the refrigerator 100 in the upright state, as shown in FIG. At this time, in the refrigerator 100, one carrier holds the grip 7 provided at the upper corner of the refrigerator body 1, and the other carrier holds the carrying handle 6 and is lifted and carried. Here, as in the conventional refrigerator, when a part of the opening edge of the opening is exposed to the outside, the carrier's finger opens the opening when transporting the refrigerator or grasping the transport handle. There is a risk that the edge may be touched and injured.

  Therefore, in the refrigerator 100 according to the present embodiment, one opposing opening edge of the opening 50 into which the carrying handle 6 formed on the outer surface of the refrigerator main body 1 is fitted is bent toward the inside from the same opening edge. Rib 51 is formed, and a concave storage portion 62 for storing the rib 51 is formed in one opposing flange portion 61a provided along the opening edge of the carrying handle 6, and the other opposing flange portion 61b is formed. In addition, sandwiching portions 63 and 64 are formed to sandwich the opening edge of the opening portion 50 together with the other flange portion 61b. Therefore, the refrigerator 100 completely covers the opening edge of the opening 50 by the storage portion 62 of the transport handle 6 and the sandwiching portions 63 and 64. Therefore, during transport of the refrigerator 100 or gripping the transport handle 6 In this case, a situation in which the carrier's finger touches the opening edge of the opening 50 of the bottom plate 5 to be injured can be reliably prevented, and the carrying operation can be performed safely.

  By the way, the handle 6 for conveyance forms a holding part also in the flange part 61a which opposes along the depth direction Y of the refrigerator main body 1 among the flange parts 61 provided along the opening edge, and provides the storage part 62. Alternatively, a configuration may be considered in which the opening edge of the opening 50 is covered only by the holding portion. However, with the above configuration, it is difficult for the carrying handle 6 to be attached to the opening 50 by deforming the holding portion. Therefore, in the refrigerator according to the present embodiment, the flange portion 61b opposed along the width direction X of the refrigerator 100 among the flange portions 61 provided along the opening edge in consideration of the attachment ease of the transport handle 6 The clamps 63 and 64 are formed only on the

  Moreover, the opening part 50 is formed in the bottom face plate 5 of the refrigerator main body 1, and the refrigerator 100 which concerns on this Embodiment has comprised the rectangular shape along the depth direction Y of the refrigerator main body 1 and the width direction X. And in the refrigerator 100, the rib 51 is formed toward the inside of the refrigerator from the opening edge in the depth direction Y of the refrigerator 100, and the flange portion 61a is provided along the opening edge in the depth direction Y of the refrigerator main body 1 Is formed. The sandwiching portions 63 and 64 are formed on the flange portion 61 b provided along the opening edge in the width direction X of the refrigerator main body 1. Therefore, the refrigerator 100 is opened at the sandwiching portions 63 and 64 against the force of the carrier acting in the vertical direction (the depth direction Y of the refrigerator main body 1) when the refrigerator 100 is turned down and transported so that each door faces upward. Since the opening edge of the portion 50 can be firmly held and held, the carrying handle 6 does not come off from the opening 50, and the carrying operation can be performed safely.

  Further, in the refrigerator 100 according to the present embodiment, since the groove widths H1 and H2 formed by the flange portion 61b and the sandwiching portions 63 and 64 are 1 mm or more and 5 mm or less, the carrier is the flange portion 61b and the sandwiching portion 63, Can not put a finger between 64 and. Therefore, this refrigerator 100 is more effective when the carrier touches the opening edge 50 of the opening 50 of the bottom plate 5 when the carrier is carrying the refrigerator 100 or grasps the carrying handle 6 to be injured. Can be prevented.
