Referring to FIG. 2, the cooling box 4 has a first cooler 13 forming its bottom, left and right plastic plates 14 and 15 forming its left and right sides, A second cooler 16 forming an upper surface and a back surface, and a plastic gutter member 17 connecting the lower rear end of the second cooler 16 and the rear end of the first cooler 13. It is constructed by connecting. The first cooler 13 has an evaporation tube 19 arranged on a flat cooling sheet 18, and the second cooler 16 has a ceiling part 20a that slopes downward sequentially toward the rear, and a ceiling part 20a that slopes downward in sequence. Cooling sheet 20 having a back plate portion 20b hanging down from 20a
An evaporation tube 21 is disposed in the evaporation tube 21. Here, the second cooler 16 is set to exhibit a cooling temperature lower than that of the first cooler 13 by, for example, 5° C. or more, so that frost is concentrated on the second cooler 16. .
The opening end of the cooling box 4 is formed with a flange that projects outward, and the opening edges of the cooling box 4, for example, the ends of the left and right side plates 14 and 15, are respectively engaged. Two joining holes 22 are formed. Furthermore, the cooling sheet 1 in the second cooler 16
