Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an ice shaver used for commercial or household use.

Conventional structure and its problems Conventionally, in this type of ice cutting machine, the rotary blade has a plurality of forward-inclined blades on a truncated conical disk.
It was common to have an annular plate screwed onto it. However, with this configuration, when driving with ice, broken ice accumulates on the annular plate due to centrifugal force and comes into contact with stationary parts, causing abnormal noises and the accumulation of ice. There was a problem that ice treatment could not be done indefinitely because it took time for the ice to melt.

OBJECTS OF THE INVENTION The present invention solves these conventional problems and provides an easy-to-use ice shaver.

Structure of the Invention The ice shaver of the present invention is provided with a rib-like protrusion on the upper surface of the annular plate at the top of the rotating blade, and the rib-like protrusion leads the center in the direction of rotation. Even if ice rises to the upper surface of the annular plate, this broken ice is guided radially outward along the sloped surface of the rib-like projection and is immediately scraped off from the gap between the water storage chamber and the rotary blade.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIGS. 1 to 4, reference numeral 1 denotes an ice shaver main body (hereinafter referred to as the main body), and a cylindrical water storage chamber 2 is provided inside and above the main body 1.
A drain hole 3 is provided at the lowest point of the ice storage chamber 2. A hose 4 is connected to this drain hole 3 to guide water generated in the water storage chamber 2 to a water tray 5. In addition, in the ice storage chamber 2, a rotary blade 9 having a plurality of blades 8, which are tilted forward in the rotation direction and whose center portion is in front, is mounted on the inclined portion 7 of the truncated conical disk 6. It is pivotally supported and serves to press the ice 10 in the ice storage chamber 2 against the side wall. Rotating blade 9
An annular plate 11 is screwed onto the blade 8 on the top of the blade 8.
is provided, and has a function of reducing the movement of the ice 10. Moreover, on the upper surface of the annular plate 11,
A rib-like protrusion 12 is formed whose center portion is in front in the rotation direction A.

An input port 13 for ice 10 is formed above the ice storage chamber 2. 14 is a main body lid. Also ice storage room 2
A cutting blade 21 and an ice discharge port 15 are provided on the front wall of the ice holder, and by operating an adjustment knob 16, the amount of protrusion of the cutting blade 21 can be adjusted, and the roughness of the ice 10 to be shaved can be changed. It's getting old. Further, an electric motor 17 is installed inside the main body 1 on the lower side, and a reduction gear 18 composed of a planetary gear is connected to the tip of the electric motor 17. The rotation of the electric motor 17 is controlled by this reduction gear 18. This rotation is decelerated and transmitted to the rotating blades 9 through the rotating shaft 19.

The operation in the above configuration will be explained. Body lid 14
When the main body lid 14 is closed again and a switch (not shown) is turned on, the rotary blades 9 begin to rotate. When a certain amount of ice 10 is shaved off, broken ice 20 will accumulate on the upper surface of the annular plate 11 due to centrifugal force, but this broken ice will be guided radially outward along the inclined surface of the rib-shaped protrusion 12, and the ice will be stored. It is immediately scraped off from the gap between the chamber 2 and the disk 6.

Effects of the Invention As is clear from the above description, the ice shaver of the present invention has rib-like protrusions on the upper surface of the annular plate at the top of the rotary blade, which are more advanced in the direction of rotation toward the center. Even if broken ice accumulates on the top surface of the annular plate due to centrifugal force, this broken ice is guided radially outward along the sloped surface of the rib-like protrusion and is immediately scraped from the gap between the ice storage chamber and the rotating blade. Since it is dropped, broken ice does not accumulate, making it easy to use.
