Description

  The present invention relates to a refrigerator, and more particularly to a refrigerator provided with a transport handle.

  Refrigerators are often equipped with a moving roller on the bottom, but the diameter is around 30 mm, so it is effective for moving over a short distance in a flat place, but steps such as a sill in a house Because it was impossible to get over, the refrigerator had to be lifted and transported when it was newly installed or moved.

  However, as the size of the refrigerator has increased, the weight has increased, so except for small refrigerators, a handle is required to lift and transport the refrigerator. A refrigerator provided with a handle has been proposed (see, for example, Patent Document 1).

Conventionally, when transporting a refrigerator, the depth direction is usually upside down with the front door side up, in order to prevent the refrigerator door from opening carelessly and causing damage to the door itself or the house. It is.
However, the size of the refrigerator has further increased, and refrigerators having a large size in the left-right direction and a small size in the depth direction have appeared. And the dimension in the left-right direction of the refrigerator may be larger than the entrance of a general house, and the dimension in the depth direction may be smaller than the dimension of the entrance. In such a case, the refrigerator must be transported in the left-right direction. I had to.

  Since such a problem cannot be dealt with by the carrying handle of Patent Document 1, a refrigerator is proposed in which a recess is provided on at least one surface other than the front and back surfaces, and the recess is used as a carrying handle (for example, Patent Document 2).
