Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an ice shaving machine for producing snow-like ice from ice cubes, that is, ice cubes produced in a refrigerator or an ice maker. This invention relates to an ice shaver with a soundproofing device that prevents noise by installing ice guide vanes.

[Prior Art] The structure of a conventional ice shaver is shown in the sectional view of FIG.
A cutting case 16 fixed to the machine base has an inverted conical shape, and a rotary blade 10 having a plurality of blades is driven by a motor 14 on the inner surface of the cutting case 16.
It is fixed to a rotating shaft supported by 6. A shaved ice outlet 20 is open in the cutting case 16, and an ice cutting blade 22 faces the outlet 20.

A rotating ring 26 adjacent to the upper edge of the cutting case 16 is fixed to the upper end surface of the rotary blade 10, and a cylindrical rotating hopper 28 whose diameter decreases upward is attached to this rotating ring 26. ,
It rotates together with the rotating blade 10.

In order to obtain snow-like ice from ice cubes using an ice shaver with such a configuration, ice cubes are introduced through the upper opening of the rotating hopper 28 and the inside of the cutting case 16 is filled with ice cubes.
Normally, it is further inserted to near the upper edge of the rotating hopper 28. After that, when the electric motor is started and the rotor 10 is rotated, the ice cubes are shaved by the ice cutting blade 22 while being pressed against the inner surface of the cutting case 16 by centrifugal force due to the rotation of the rotor 10, and 16 and is discharged from the discharge port 20.

At this time, the ice cubes in the cutting case 16 are
It rotates within the case 16, partitioned to some extent into a plurality of sections by. On the other hand, the ice cubes in the hopper 28 freely move 360 degrees due to the rotation of the hopper 28 and the rotation of the ice cubes in the case, but this movement continues as an ice cutting action and the ice cubes in the hopper 28 decrease. As the ice cubes collide more violently with each other, the inner wall of the hopper 28 and the ice cubes collide more frequently, and the collision force also increases.
Therefore, there is a problem in that loud noise is generated and causes discomfort to the operator.

[Problems to be solved by the invention] The present invention was developed in view of the problem that conventional ice shavers generate large noises due to the forced rotation of ice cubes placed inside them during ice cutting operations. what has been done,
To provide an ice cutter which prevents the generation of noise by regulating the movement of ice cubes in a rotating hopper and making the transition into a cutting case relatively smooth.

[Means for solving the problem] The present invention has been developed after extensive research into the causes of noise generated during ice cutting by an ice shaver, and as a result, the noise is significantly reduced by regulating the movement of ice cubes in the rotating hopper. This led to new knowledge of what could be done and the completion of this invention.

That is, in the ice cutting machine of the present invention, a rotary blade with a plurality of blades is driven by a motor on the inner surface of a cutting case that is fixed to a machine base equipped with a shaved ice outlet where the cutting blade faces. It is fixed to a rotating shaft that is pivotally supported by a case, and a rotating ring is fixed to the upper edge of the rotary blade, and a cylindrical rotating hopper is provided above the rotating ring, and on the inner surface of the rotating hopper,
(At least) the same number of guide vanes as the rotor blades are formed so as to be in contact with the blades of the rotor blades.

[Operation] The ice cubes put into the rotating hopper collide with the inner wall of the rotating hopper in conjunction with the rotation of the rotating hopper and the movement of the ice cubes rotated by the rotary blades below. During this time, the range of movement (rotation) is restricted to within that section by the guide vanes provided on the rotating hopper, so the degree of collision is significantly reduced, and furthermore, the degree of collision is significantly reduced. Since it is rotated (revolving) together with the rotary hopper and rotor blades, the movement from the rotary hopper to the cutting case is also within the same compartment, so it can be done extremely smoothly and noise generation during this time can be prevented. .

[Embodiment] A preferred embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a side sectional view of an embodiment of the present invention.
A cutting case 16 fixed to the machine base has an inverted conical shape, and a rotary blade 10 with three blades is mounted on the inner surface of the cutting case 16.
is fixed to a rotating shaft 12 driven by a motor 14 and supported by the case 16, and the case 16 has an opening 20 for discharging shaved ice, into which an ice cutting blade 22 faces. I'm here. A rotary ring 26 adjacent to the upper edge of the cutting case 16 is fixed to the upper end surface of the rotor blade 10, and the rotary ring 26 has a cylindrical rotary hopper whose diameter decreases upward and is open at the top and serves as an input port. 28 is attached and the hopper rotates together with the rotor 10.

Three guide vanes 30 are provided on the inner surface of the rotating hopper 28.
are attached so as to make an angle of 120° to each other, and the lower ends of the guide vanes 30 are in contact with the upper edges of the three blades of the rotary blade 10, respectively.

In order to obtain snow-like ice from ice cubes using an ice shaver with such a configuration, ice cubes are introduced from the rotating hopper 28 to fill the container 16 with ice cubes, and then the ice cubes are poured into the container 16 until it reaches near the upper edge of the rotating hopper 28. put in. After that, when the electric motor is started and the rotor 10 is rotated, the ice cubes inside are shaved by the ice cutting blade 22 while being pressed against the inner surface of the cutting case 16 by centrifugal force due to the rotation of the rotor 10.
The cutting case 16 is discharged from the discharge port 20.

At this time, the ice cubes in the rotating hopper 28 rotate together with the hopper 28 in a compartment partitioned by three guide vanes 30 provided on the inner surface of the rotating hopper 28, so that each ice cube is affected by this rotation. As a result, the range of movement becomes restricted and narrow. Therefore, the ice cube rotates in the hopper 28
The noise inside the hopper 28 is significantly reduced, since collision phenomena occurring with the inner walls of the hopper 28 or between each other are very limited.

Incidentally, since the inside of the cutting case 16 is originally partitioned by rotary blades and the movement range of the ice cubes is limited, there is not much noise. Further, since the guide vanes 30 and the vanes of the rotary vanes 10 are adjacent to each other and form a continuous compartment, the ice cubes can be smoothly transferred from the rotary hopper 28 to the cutting case 16, so that during the transition Collisions between ice cubes do not occur.

[Effects of the invention] As described above, the present invention provides the same number of guide vanes adjacent to the plurality of blades of the rotary blades in the cutting case on the inner surface of the rotary hopper, so that the blades are partitioned by the rotary blades. Since a continuous compartment is formed above the cutting case, the ice cubes in both chambers fed into the cutting case from the rotary hopper are partitioned until they are cut and discharged by the rotation of the rotary blades and the rotary hopper. The ice cubes move smoothly within a certain section, and there is no violent collision between the inner wall of the rotating hopper and the ice cubes, so the noise generation is significantly reduced and the cutting efficiency is also good due to the smooth transition of the ice cubes. There is an effect. In addition, the number of guide vanes in the example was the same as that of the rotor blades, but there was one in the middle.
A similar effect can be obtained by adding an additional blade to double the number of rotor blades.
