Description

[Detailed Description of the Invention] The present invention relates to an ice crusher that crushes ice cubes into appropriate sizes to speed up the cooling of drinks and make it easier to put ice into containers, for example.

Embodiments of the present invention shown in the drawings will be described in detail below.

FIG. 1 is a top view showing the main parts of the ice crusher. The main body 1 of the ice crusher is box-shaped, and the left side forms a mechanism part 2 that houses the motor, speed reduction mechanism, switch, etc., and the right side A crushing chamber 3 is formed in the upper part and a container storage part is formed in the lower part.

The grinding chamber 3 has upper and lower surfaces open and has an inlet at the top and an outlet at the bottom, and a lid (not shown) is provided on the inlet so that it can be opened and closed.

Further, the container storage section is located below the grinding chamber 3 and stores a receptacle that can be taken in and out.

The rotating shafts 4 are rotated by a motor via a speed reduction mechanism, and project horizontally from the mechanical part 2 into the grinding chamber 3, and are spaced from each other at a predetermined distance in the axial direction and at a predetermined distance from each other in the circumferential direction. A plurality of rotary blades 5 positioned at different angles are fixed using various spacers 6, 7.8.

The rotary blade 5 has side edges facing in the same rotational direction on both sides of the rotary shaft 4 as blade portions 5a, 5a.

Each of the spacers 6.7 has a cylindrical shape, and in particular has a groove 6a extending in the radial direction at one end of the spacer 6.

Further, the spacer 8 has a cylindrical shape, has a stepped portion on its outer peripheral surface, and has a large diameter portion 8a and a small diameter portion 8b.

Thus, the rotating shaft 4 has a spacer 6, a rotating blade 5,
Spacer 7.8 The rotary blade 5, spacers 8, 7, rotary blade 5, and spacer 6 are fitted in order, and the fixing pins 9, 9 that penetrate the rotating shaft 4 are inserted into the grooves 6a, 6a of the spacer 6.6 at both ends. By engaging these rotary blades 5 and spacers 6,
7. 8 in place.

The fixed blade 10 is located between the respective rotary blades 5, and is loosely fitted into the small diameter portion 8b of the spacer 8 with its center portion, and has a blade portion 10a formed on the edge of the portion protruding to one side of the rotating shaft 4, and the other. An ice block fall prevention piece 10b is formed at the side protruding portion.

Further, a spacer 11 is located between the ends of the fixed blade 10 on the side of the blade part 10a, and the end part of the side of the blade part 10a is rotatably fitted to the support shaft 12 together with the spacer 11. The grinding chamber 3 is supported by a bearing portion 13.13 protruding from the inner surface of the grinding chamber 3.

The fixed blade 10 is loosely fitted into the small diameter portion 8b of the spacer 8, and the end on the side of the blade portion 10a is supported on the support shaft 12, and the end on the side of the prevention piece 10b is a free end. With the 12 side as a fulcrum, there is play in the direction of the arrow within the length of the small diameter portion 8b, and this play allows the interval between the fixed blades 10, 10 to be varied.

The support shaft 12 is in a state where it can freely rotate relative to the bearings 13, 13, and due to the rotation, the rotary blade 5 and the blade portion 10 of the fixed blade 10 are
A plate-shaped particle size adjusting body 14 that appears and retracts between the spaces a is fixed.

This particle size regulator 14 is connected to the blade portions 10 of the rotary blade 5 and the fixed blade 10.
It changes the area of the passage through which crushed ice pieces pass by appearing and retracting between the sections a, and has a cut R14a through which the rotary blade 5 passes in the protruding state.

The support shaft 12 has one end extending outward through one side wall of the crushing chamber 3, and is configured to be able to be rotated from the outside by fixing the heir 15 thereto.

Next, its effect will be explained.

First, ice cubes to be crushed are introduced into the crushing chamber 3 through the inlet, the lid is closed, and the motor is driven by closing the switch, causing the rotating shaft 4 to rotate counterclockwise in FIG. Thus, the rotary blade 5 crushes the ice block by cooperation of its blade part 5a and the blade part 10a of the fixed blade 10, and the crushed ice pieces fall and are stored in the receiver from the outlet.

Therefore, by taking out the receiver from the main body 1, crushed ice pieces can be obtained.

In such a grinding chamber, by operating the current child 15, the particle size control body 1 is
4 as shown in FIGS. 1 and 2, a rotary blade 5 and a fixed blade 10.
If the blade portion 10a is made to protrude, the passage through which the crushed ice pieces pass becomes narrower, so that the ice cubes are finely crushed and the obtained ice pieces become smaller.

On the other hand, if the particle size regulator 14 is moved along the wall surface of the crushing chamber 3 by manipulating the heir 15, the passage through which the crushed ice pieces pass becomes wider, and the resulting ice pieces become larger.

In other words, the particle size of the ice pieces obtained can be adjusted by operating the particle size regulator 14 to move in and out.

Further, when crushing ice blocks as described above, the fixed blade 10 moves in the direction of the arrow due to the force received, thereby changing the distance between the fixed blades 10 and 10 and the distance between the fixed blade 10 and the inner surface of the crushing chamber 3. Fixed blade 10 in the range out of reach of rotary blade 5
．． Ice blocks will no longer clog and remain in the 10-space.

That is, if the fixed blades 10 are firmly fixed without any play, the distance between the fixed blades 10 and 10, and the distance between the fixed blades 10 and the crushing chamber 3.
Since the distance between the inner surfaces is constant, once an ice block gets stuck between the fixed blades 10 and 10 in a range out of the reach of the rotary blade 5, it will remain in that position without falling, and the ice block will melt after the crushing is finished. This results in dripping or falling ice cubes, leading to the disadvantage that the tabletop gets wet when the receiver is removed, but this embodiment can eliminate such disadvantages.

In particular, in this embodiment, since the rotary blades 5 are positioned circumferentially offset from each other by a predetermined angle, forces in opposite directions are applied to the fixed blades 10 alternately, and the fixed blades 10 alternately Since it moves in the opposite direction, there will be no ice blockage or residual ice between the fixed blades 10° and 10°.

According to the present invention having the above configuration, the particle size of the ice pieces can be easily obtained by controlling the particle size of the ice pieces by operating the particle size control body, and it is possible to easily obtain ice pieces of a size that matches the size of the container. The fixed blade can be mounted so that it can be operated externally using a support shaft that supports the fixed blade in a predetermined position in conjunction with the rotating shaft.The use of the above support shaft simplifies the structure and makes it practical. It is in extremely good condition.
