In each of the plurality of blades 34, the distance 34cL between the tips of the adjacent blades 34 is shorter than the distance 34dL between the ends of the adjacent blades 34.

The sterilizer 100 may irradiate ultraviolet light toward the inner circumferential surface 34a and the outer circumferential surface 34b of the blade 34. In addition, the sterilization device 100 may irradiate ultraviolet light toward the rotating plate 32 . The sterilization device 100 may irradiate ultraviolet light toward the rim 36 .

Referring to FIG. 8, when the end 34d of the blade 34 is disposed in front of the sterilizer 100, the front end 34c of the blade 34 extends to be disposed in front of the sterilizer 100.

Each of the plurality of blades 34 is formed so that the length of the outer circumferential surface 34b is longer than the length of the inner circumferential surface 34a.

Through the shape of the blade 34 and the arrangement of the sterilizer 100, the outer circumferential surface 34b and the inner circumferential surface 34a of the blade 34 can be sterilized.

Although the preferred embodiments of the present invention have been shown and described above, the present invention is not limited to the specific embodiments described above, and in the technical field to which the present invention belongs without departing from the gist of the present invention claimed in the claims. Various modifications and implementations are possible by those skilled in the art, and these modifications should not be individually understood from the technical spirit or perspective of the present invention.
