  FIG. 8 is an explanatory view showing a procedure for attaching the carrying handle of the refrigerator according to the embodiment of the present invention to the opening of the bottom plate. As shown in FIG. 8, when the transport handle 6 is attached to the opening 50 of the bottom plate 5, the opening edge of the opening 50 is first held by the holding portion 63 on the front side, and the rib 51 is After being stored, the opening edge of the opening 50 is held by the holding portion 64 on the rear surface side. After attaching the carrying handle 6 to the opening 50, a foamed heat insulating material such as urethane foam is injected into the inside sealed by the inner box and the outer box 10.

  In the case where the carrying handle 6 is attached to the opening 50 in the above procedure, the holding portion 64 provided on the rear surface side is formed to have a convex dimension protruding outward slightly smaller than the holding portion 63 provided on the front side. It is desirable to do. This is because the carrying handle 6 can be easily attached to the opening 50 by forming the holding portion 64 on the rear surface side to be attached later to be small. On the other hand, when carrying the refrigerator 100, in the refrigerator 100 in which each door is turned upside down, the power of the carrier is applied to the holding portion 63 provided on the front side. For this reason, it is desirable that the front-side holding portion 63 has a configuration in which the size of the protrusion protruding outward is increased, so that the opening edge of the opening 50 can be firmly held and held.

  Although not shown in detail, the refrigerator 100 according to the present embodiment has a flange 61 a of the flange 61 provided on the carrying handle 6, which is opposed to the refrigerator main body 1 along the depth direction Y. Alternatively, a configuration in which holding portions 63 and 64 for holding the opening edge of the opening portion 50 of the bottom plate 5 together with the flange portion 61a may be formed. In this case, the rib 51 is formed at the opening edge in the width direction X of the refrigerator body 1 from the opening edge of the opening 50 of the bottom plate 5 toward the inside of the refrigerator. In the flange portion 61 of the carrying handle 6, a concave storage portion 62 for storing the rib 51 provided on the bottom plate 5 is formed in the flange portion 61 b facing along the width direction X of the refrigerator 100. However, in the refrigerator in which each door is turned upside down when carrying the refrigerator 100, the force of the carrier acts in the vertical direction (the depth direction Y of the refrigerator 100), so that the opening edge of the opening 50 is firmly held. It is preferable that the holding portions 63 and 64 that can be held by holding are formed on the flange portion 61b facing along the width direction X of the refrigerator 100.

  When it is difficult to transport the refrigerator 100 having the above configuration in an upright state, as shown in FIG. 1, each door is turned upside down, and is transported while being held in pairs. At this time, the refrigerator 100 is lifted and carried by one carrier grasping the grip 7 provided at the upper corner of the refrigerator body 1 and the other carrier grasping the carrying handle 6. Here, when a part of the opening edge of the opening is exposed to the outside as in the conventional refrigerator, the finger of the carrier is opened during the transportation of the refrigerator or when gripping the carrying handle. There is a risk of touching the edges and causing injury.

  Therefore, in refrigerator 100 according to the present embodiment, one of the openings 50 into which transport handle 6 formed on the outer surface of refrigerator main body 1 is fitted is bent from the opening edge toward the inside of the refrigerator. A rib 51 is formed, and a concave storage portion 62 for storing the rib 51 is formed on one of the opposed flange portions 61 a provided along the opening edge of the carrying handle 6, and the other opposed flange portion 61 b is provided. Further, holding portions 63 and 64 for holding the opening edge of the opening portion 50 together with the other flange portion 61b are formed. Therefore, since the refrigerator 100 completely covers the opening edge of the opening 50 with the storage portion 62 of the carrying handle 6 and the holding portions 63 and 64, the refrigerator 100 holds the carrying handle 6 during the transportation of the refrigerator 100. At this time, it is possible to reliably prevent a situation in which the carrier's finger touches the opening edge of the opening 50 of the bottom plate 5 and is injured, and the carrying operation can be performed safely.

  By the way, the carrying handle 6 forms a holding portion also in the flange portion 61a facing along the depth direction Y of the refrigerator main body 1 among the flange portions 61 provided along the opening edge, and the storage portion 62 is provided. A configuration is also conceivable in which the opening edge of the opening 50 is covered only by the holding portion. However, if the transport handle 6 is configured as described above, it is difficult to deform the holding portion and attach it to the opening 50. Therefore, in the refrigerator of the present embodiment, of the flange portions 61 provided along the opening edge in consideration of the ease of attachment of the carrying handle 6, the flange portion 61b facing along the width direction X of the refrigerator 100 is included. Only the holding portions 63 and 64 are formed.

  Further, in refrigerator 100 according to the present embodiment, opening 50 is formed in bottom plate 5 of refrigerator main body 1, and has a rectangular shape along depth direction Y and width direction X of refrigerator main body 1. In the refrigerator 100, the rib 51 is formed from the opening edge in the depth direction Y of the refrigerator 100 toward the inside of the refrigerator, and the storage portion 62 is provided along the flange portion 61 a provided along the opening edge in the depth direction Y of the refrigerator body 1. Is formed. The holding portions 63 and 64 are formed on a flange portion 61b provided along the opening edge of the refrigerator body 1 in the width direction X. Therefore, the refrigerator 100 is opened by the holding portions 63 and 64 with respect to 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 transported with the doors turned 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, since refrigerator 100 according to the present embodiment has groove widths H1 and H2 formed by flange portion 61b and holding portions 63 and 64 of 1 mm or more and 5 mm or less, the transporter can handle flange portion 61b and holding portion 63, You can't put your finger between them. Therefore, the refrigerator 100 is more effective in preventing the carrier from touching the opening edge of the opening 50 of the bottom plate 5 and being injured while the carrier is carrying the refrigerator 100 or gripping the carrying handle 6. Can be prevented.

  Although the present invention has been described based on the embodiment, the present invention is not limited to the configuration of the above-described embodiment. Although the carrying handle 6 of the illustrated embodiment is shown as being attached to the bottom plate 5 of the refrigerator main body 1, it may be provided on the back or top surface of the refrigerator main body 1, for example.
