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 together using various spacers 6, 7, and 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, R6a extending in the radial direction is formed on one end surface of the spacer 6.

Further, the spacer 8 has a cylindrical shape, and has a stepped portion formed 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 7.8J1 rotating blade 5, spacer 8,7, rotating blade 5
These rotary blades 5 and spacers 6 are fitted in order and the fixing pins 9, 9 provided through the rotary shaft 4 are engaged with the grooves 6a, 6a of the spacers 6.6 at both ends.
．． 7. Fix 8 in place.

The fixed blade 10 is located between the 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 upper edge of the portion protruding to one side of the rotary shaft 4, 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 fitted together with the spacer 11 into a shaft 12, and the shaft 12 is used to connect the crushing chamber 3. It is supported by bearings 13, 13 protruding from the inner surface.

Therefore, the fixed blade 10 is loosely fitted on the rotating shaft 4 side, and the end on the side of the blade part 10a is supported by the shaft 12, and the end on the side of the waist prevention piece 10b is the free end. Small diameter part 8b
The space between the fixed blades 10 and 10 can be varied by allowing play in the direction of the arrow within the length range.

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.

Therefore, when crushing ice blocks as described above, the fixed blades 10 move in the direction of the arrow due to the force received, thereby causing the fixed blades 10, 1 to move in the direction of the arrow.
Since the interval between the fixed blades 10 and 10 and the interval between the fixed blades 10 and the inner surface of the crushing chamber 3 are changed, ice blocks will not clog and remain between the fixed blades 10 and 10 in a range that the rotary blade 5 cannot reach.

That is, if the fixed blade 10 is firmly fixed without any play, the distance between the fixed blades 10 and the crushing chamber 3 will be reduced.
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 would result in dripping or falling ice cubes, which would result in the tabletop becoming wet when the receiver was removed, but this embodiment can eliminate such drawbacks.

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 By moving in the opposite direction, there will be no blockage or residual ice blocks between the fixed blades 10° and 10°.

In this case, as long as the fixed blades are supported with an appropriate amount of play in order to make the interval between the fixed blades variable, there is no restriction on the structure.

According to the present invention having the above-mentioned configuration, ice blocks do not become clogged and remain between the fixed blades, and there is no inconvenience caused by ice blocks remaining after crushing, and the fixed blades do not move toward the rotating shaft side. It is supported in a fitted state, and a blade is formed on the upper edge of the part that protrudes to one side from the rotating shaft, and the end is supported on the inner side of the crushing chamber, so it can be supported on a cantilever. Compared to this, there is less risk of breakage etc. during crushing, and there are also fewer restrictions on the material, making it very superior in practice.
