detailed description

The present invention will be described in detail below with reference to the drawings and specific embodiments.

The present invention discloses a novel simple refrigerator 100 that can be manufactured by a consumer, and the size and size of the simple refrigerator 100 can be arbitrarily set.

Referring to FIGS. 1 to 4, the simple refrigerator 100 is provided with a casing 1, a door body 2 connected to the casing 1 via a hinge 4, and a semiconductor refrigeration module 3 mounted on the casing.

Referring to FIG. 3 and FIG. 5, the hinge 4 is provided with a fixing plate 41 and a rotating shaft 42 protruding upward from one end of the fixing plate 41. One end of the fixing plate 41 not provided with the rotating shaft 42 is fixed on the casing 1, and one end of the fixing plate 41 with the rotating shaft 42 lifts up the bottom of the door body 2 while the rotating shaft 42 is embedded in the The door body 2 is internally rotated for the door body 2 to rotate around the casing 1.

The casing 1 includes a rear wall 11 , a top wall 12 connected to the rear wall 11 and a bottom wall 13 , and two side walls 14 respectively connecting the top wall 12 and the bottom wall 13 . A two-layer rack 16 that divides the casing 1 into three storage spaces 15 is also provided in the casing 1. The semiconductor refrigeration module 3 is mounted on the rear wall 11 of the uppermost first storage space 15.
