Description

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

Configuration of conventional example and its problems The present inventors have considered an ice shaver as shown in FIGS. 1 to 3. That is, a disk 27 having a plurality of rotary blades 25 on its upper surface rotated by an electric motor 30 is provided in a cylindrical ice storage chamber 22, and an opening 28 is provided approximately vertically in a part of this ice storage chamber 22. The cutting blade 26 faces into the opening 28 through the mounting base 31, and a discharge hole is provided at the lowest position of the ice storage compartment 22 in order to discharge the ice cut by the cutting blade 26 to the outside of the ice storage compartment 22. 22a is provided, and its discharge hole 2
A pipe 23 is connected to 2a, and the tip of the pipe 23 is guided to a saucer 24. Further, a discharge port 29 for discharging cut ice to the outside of the main body 21 is provided at a position opposite to the opening 28.

When ice is cut with the ice shaving machine having the above configuration, the ice cubes placed in the ice storage chamber 22 are pressed against the outer wall of the ice storage chamber 22 by the rotating blades 25 and the cutting blades 26
The ice cubes are cut by the rotating blade 25 and discharged to the outside of the main body 21 through the opening 28 and the outlet 29.
It is crushed finely. Therefore, small pieces of crushed ice accumulate between the cutting blade 26 and the opening end surface 28a on the rear side of the cutting blade 26 with respect to the rotational direction of the rotary blade 25, and the accumulated ice accumulates on the cutting blade 26. The height of the protrusion into the ice storage chamber 22 is the same as or higher than that, and the blade part of the cutting blade 26 is covered. For this reason, even though the protrusion of the cutting blade 26 is constant, the roughness of the cut becomes fine and cutting becomes impossible, so it is necessary to remove the small pieces of ice that have become stuck each time. In other words, there was a problem that continuous cutting of a large amount could not be performed.

OBJECTS OF THE INVENTION It is an object of the present invention to provide an ice shaving machine that solves these problems, improves cutting performance, and enables continuous cutting.

Structure of the Invention In order to achieve the above object, an ice shaving machine of the present invention includes a substantially cylindrical ice storage chamber, a rotating blade provided in the ice storage chamber, and an opening provided in a part of the side wall of the ice storage chamber. The cutting blade is formed by a cutting blade that faces inside the rotary blade, and a cutting blade back surface that is formed behind the cutting blade with respect to the rotational direction of the rotary blade, and an opening part end surface that faces the cutting blade back surface. The ice storage chamber is formed so that the space is continuously widened from the top to the bottom of the ice storage chamber. With this configuration, the ice crushed by the rotating blade is distributed between the back surface of the cutting blade and the end surface of the opening. Even if it gets caught in the ice, it is pushed down by the ice that gets caught one after another and is pushed downward into the ice storage chamber, so there is no change in cutting roughness and a large amount of continuous cutting can be done.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings.

4 to 9, 1 is the main body of the ice scraper (hereinafter referred to as the main body), and a cylindrical ice storage chamber 2 is installed at an angle inside the main body 1, and inside this ice storage chamber 2. A groove 2a is formed on the outer periphery of the bottom. And inside the ice storage chamber 2, it is rotatably supported,
A disk 7 having a plurality of rotating blades 5 is provided, and the rotating blades 5 rotate the ice and press it against the side wall surface of the ice storage chamber 2.

In addition, an opening 8 is provided approximately vertically in the lowest side wall of the ice storage compartment 2, and a cutting blade mount 18 is provided within the opening 8.
A cutting blade 6 fixed to the front face is shown. By operating the adjustment knob 9, the amount of the cutting blade 6 that protrudes from the inner wall of the ice storage chamber 2 can be adjusted via the cutting blade mount 18, and the roughness of cutting the ice can be changed. Further, an electric motor 10 is installed in the inner lower part of the main body 1, and a reducer 11 consisting of a planetary gear is connected to the tip of a shaft 10a of the electric motor 10. The rotation is decelerated and transmitted to the disk 7 via the rotating shaft 12. Furthermore, the upper part of the main body 1 has a switch 13 and a safety switch 14, and the main body lid 1
5 is open, the safety switch 14 is turned off to create a safe structure in which the disc 7 does not rotate.

Also, a discharge port 1 is provided outside the opening 8 of the ice storage chamber 2.
There are 6. In addition, with respect to the rotation of the rotating blade 5,
The inclination angle of the aperture end surface 8a is adjusted so that the space 17 formed by the back surface of the cutting blade 6 and the aperture end surface 8a facing the back surface becomes continuously wider from the top to the bottom of the ice storage chamber 2. is changed as shown in FIGS. 7 to 9. Further, the space 17 may be widened by providing an inclination (not shown) in the attachment of the cutting blade 6.

The operation in the above configuration will be explained. Body lid 15
Open the lid 15, put ice in the ice storage compartment 2, and then close the lid 15 again.
When the switch 13 is closed and the switch 13 is turned on, the rotating blade 5
The disk 7 having a rotation angle rotates, and the ice is pressed against the inner wall surface of the ice storage chamber 2 by its own centrifugal force due to the rotation and by the rotating blades 5, rotates within the ice storage chamber 2, and is then cut by the cutting blade 6. The material is then cut and discharged to the opening 8 and the discharge port 16.

In addition, the water that melted in the ice storage compartment 2 collects in the groove 2a,
The drain hole 19 is guided by the pipe 3 to the saucer 4.
are collected in. In addition, small pieces of ice crushed by the rotating blade 5 etc. gradually accumulate in the space 17 formed by the back surface of the cutting blade 6 and the opening end surface 8a facing the back surface of the cutting blade 6. When the height exceeds the protrusion of the cutting blade 6, it is subjected to pressing pressure by the rotating ice. In this case, since the space 17 is formed to widen downward in the ice storage chamber 2, the accumulated ice is discharged downward, and as a result, it does not accumulate to the extent that it covers the blade portion of the cutting blade 6. Therefore, there is no change in cutting roughness, and a large amount of continuous cutting can be performed.

Effects of the Invention As is clear from the above embodiments, according to the ice shaving machine of the present invention, the cutting blade is not covered with small pieces of ice, so cutting performance is improved and a large amount of continuous cutting is possible. It has very good effects.
