Abstract

PURPOSE:To simply take makeup ice-flakes out of a vessel, by a method wherein the ice-flakes crushed are discharged from a gap between a throwing case and a rotary disk, and the ice-flakes discharged are pushed out by a rotary blade and are discharged to the outside of the vessel through a discharge opening. CONSTITUTION:By centrifugal force caused by the rotation of a rotary disk 25, crushed ice-flakes are discharged outward through a gap L1 formed between the lower end of a cylindrical part 31a and the end part of an upper surface 26a of a cylindrical part 26, and enter a chamber 45 formed of a cylindrical body 32 and the cylindrical part 26. The crushed ice-flakes in the chamber 45 are shaved by a slicing edge 29, and are turned into fine ice-flakes. Since a gap L2 formed between the lower end of a cylindrical part 32a and the rotary disk 25 is small, only the fine ice-flakes are discharged from the gap L2 by the centrifugal force of the rotary 25, and fall on the bottom part 30c of a vessel 30. By a blade H formed on the undersurface of a flange part 27 of the rotary disk 25, the fine ice-flakes falling on the bottom part 30c are scraped up with the rotation of the rotary disk 25, and are pushed out to a discharge opening through a branch way. Therefore, when a holding vessel is placed under the discharge opening, the fine ice-flakes are accumulated in the holding vessel.

The released ice pieces are pushed out by rotating blades and are discharged from the container through the outlet.

[Example] Hereinafter, an example of the ice crusher according to the present invention will be described based on the drawings.

In FIG. 1, 20 is an ice crusher;
Reference numeral 1 denotes a main body incorporating a drive motor M, and a receiving part 22 is provided at the upper part of this main body 21. A rotating shaft 23 rotated by a drive motor M projects upward from the upper surface of the receiving portion 22, and a tip 23a of this rotating shaft 23 is removably connected to a support shaft 24 of a rotary disk 25, which will be described later. The shaft 23 and the rotary disk 25 are configured to rotate integrally.

Moreover, in FIG. 1, 30 is a container placed on the receiving part 22, and a branch passage 30a for discharging ice pieces is provided at the lower part of the container 30. As shown in FIG. 2, the branch path 30a is formed by extending the bottom 30a of the container 30 in the rotational direction and tangential direction of the rotary disk 25, and has a cylindrical discharge port with a downwardly bent tip. 3°b protrudes from the side of the container 30. Note that 4° is the lid.

Inside the container 30, a charging tube 31 with openings at both upper and lower ends is disposed, and furthermore, a rotary disk 25 is disposed at a position facing the lower opening of the loading tube 31.

As shown in FIG. 3, the rotary disk 25 includes a cylindrical portion 26 having a flat upper surface 26m, and a flange 27 provided at the lower part of the peripheral wall of the cylindrical portion 26 and forming a horizontal surface 27a. A crushing blade 28 is attached to the upper surface 26a of the cylindrical portion 26, and a slicing blade 29 is attached to the horizontal surface 27a of the flange portion 27.

Furthermore, as shown in FIG. 4, on the back surface of the rotary disk 25, two blades H formed in the shape of a rectangular plate are arranged radially downward (toward the main body 21 side) at the diameter position of the rotary disk 25. It is installed protrudingly. The number of blades H is not limited to two, but one or three or more blades may be arranged radially in the radial direction of the rotary disk 25.

The charging tube 31 is integrally and continuously formed with the container 30, and includes a cylindrical tube section 31a having a diameter larger than the tube section 26 of the rotary disk 25 and smaller than the diameter of the flange section 27, and a tube section 31a for storing the ice cubes to be thrown. Guide part 3 expanded upward to guide to the cylindrical part 31a
1b.

32 is movable up and down along the cylindrical portion 31a of the input cylinder 31;
Moreover, it is a cylindrical body that is detachably attached. This cylinder 32
has a cylindrical portion 32m having approximately the same diameter as the diameter of the flange portion 27 of the rotary disk 25, and a sliding portion 32b that is slidably fitted into the cylindrical portion 31a of the charging cylinder 31. 32c is a flange provided at the bottom of the cylindrical portion 328.

As shown in FIG. 5, a pair of grooves 33 are provided on the outer periphery of the cylindrical portion 32a, extending counterclockwise from the upper end and diagonally downward. On the other hand, inside the container 30, a ring plate 34 is provided concentrically with the cylindrical body 32 and is rotatable, and the ring plate 34 is provided with a projection 35 that projects inward. It engages with the groove 33 of the cylindrical body 32. Further, the ring plate 34 is provided with an operating lever 36 extending outward, and a tip portion 3 of the operating lever 36 is provided.
6a protrudes outside the container 30 through a long hole 38 provided in the peripheral wall of the container 30 so as to extend horizontally (the first
(see figure).

Then, when the operating lever 36 is moved horizontally and counterclockwise to rotate the ring plate 34 counterclockwise, the lower end of the cylindrical body 32 touches the rotary disk 2 as shown in FIG.
5 to a position corresponding to the upper surface 26a of the cylindrical portion 26. Further, when the operating lever 36 is moved clockwise, the lower end of the cylinder 32 is lowered to a position near the horizontal surface 27a of the rotary disk 25, as shown in FIG. Then, the groove 33, the ring plate 34, and the protrusion 3
5 and the like constitute a vertical mechanism.

Next, the operation of the ice crusher with the above configuration will be explained.

First, when making shaved ice, the operating lever 36 is moved clockwise to lower the cylinder 32 to the position shown in the sixth row. Subsequently, the lid 40 is removed from the container 30, and about 7 to 8 ice cubes made from, for example, an ice cube tray of a freezer are thrown into the charging cylinder 31 from the upper end opening. After closing the lid 40, the drive motor M is activated to rotate the rotary shaft 23, and the rotary disk 25 rotates together with the rotation of the zero-rotation shaft 23.

As the rotary disk 25 rotates, the crushing blade 28 collides with the ice blocks in the cylindrical portion 31a, and the ice blocks are crushed one after another into small pieces of crushed ice. The crushed ice pieces are ejected outward from the gap L1 formed between the lower end of the cylindrical part 3]a and the end of the upper surface 26a of the cylindrical part 26 by the centrifugal force caused by the rotation of the rotary disk 25, and the crushed ice pieces are released from the cylindrical body. 32 and the chamber 45 formed by the cylindrical portion 26. Since the gap L1 is relatively large, the ice pieces entering the chamber 45 are coarse.

The crushed ice pieces that have entered the chamber 45 are then shaved by the slicing blade 29 into fine ice pieces. Since the gap L2 formed between the lower end of the cylindrical portion 32a and the rotary disk 25 is small, only minute ice pieces are released from the gap L2 by the centrifugal force of the rotary disk 25 and fall to the bottom 30c of the container 30. To go. The fine ice pieces that have fallen to the bottom 30c are
As the rotary disk 25 rotates, the particles are collected by the blades H provided on the lower surface of the flange portion 27 of No. 5, and are pushed out to the discharge port 30b via the branch path 30a. Therefore, if a container is placed under the outlet 30b, fine ice pieces will be accumulated in this container.

By the way, since the upper surface 26a of the cylindrical portion 26 of the rotary disk 25 is located at a higher position than the horizontal surface 27a of the flange portion 27, the fine ice pieces shaved by the slicing blade 29 hardly enter the cylindrical portion 31a and are Only ice chunks and crushed ice pieces will be present in section 31. Therefore, the probability that the crushing blade 28 collides with the ice block and crushed ice pieces increases, and the crushing efficiency of the crushing blade 28 improves.

Therefore, fine crushed ice pieces are created by the crushing blade 28 in a short time and discharged into the chamber 45, so that shaved ice can be made in a short time.

Next, when making coarse pieces of ice, the operating lever 36 is moved counterclockwise to raise the cylinder 32 to the position shown in FIG. Next, ice cubes are put into the charging tube 31, and the drive motor M is rotated to rotate the rotary disk 25.

In this case, the lower end of the cylinder 32 and the upper surface 2 of the flange 27
7a is large, the crushed ice pieces crushed by the crushing blade 28 and released from the gap L1 are transferred to the slicing blade 29.
The particles are released from the gap L3 and fall to the bottom 30c of the container 30 without being scraped by the particles. Then, in the same manner as above, the crushed ice pieces are transferred to the outlet 3 via the branch path 30a.
Ejected from 0b.

In this way, when making coarse pieces of ice or shaved ice, all you have to do is change the position of the lever, so the operation is simple and very convenient. In addition, the finished ice pieces are
The container 30 is removed by the blade H without being accumulated in the container 30.
Since it is discharged outside, there is no limit to the amount of ice cubes that can be input, and coarse ice pieces or shaved ice can be made continuously.

[Effects of the Invention] As described above, according to the present invention, finished ice pieces can be easily taken out from a container, and the amount of ice cubes to be input is not limited by the size of the container.
