Description

[Detailed description of the invention] This invention is designed to limit the roughness of falling ice chips by partitioning the exit part of the ice crusher, especially the hopper into which the ice blocks are fed, into ice chip falling gaps of an appropriate width. The present invention relates to an ice crusher equipped with a crushing cutter that crushes ice blocks in a hopper between a member and a falling ice piece roughness limiting member by rotation.

When using crushed ice for drinks, cooking, etc., it would be convenient if ice with different roughness could be obtained depending on the use and preference, and an ice crusher that can adjust the roughness is required. Various methods of roughness adjustment have been developed and used. One of them is known from Japanese Patent Application Laid-Open No. 12972/1983. This product is equipped with a crushing cutter at the hopper outlet so as to be divided into two parts, one for the normal rotation side and one for the reverse rotation, and a crushing cutter for the normal rotation side and the reverse rotation side of the peripheral wall of the hopper outlet parallel to the cutter axis. Fixed blades are provided with different lengths to receive the ice blocks, and the longer fixed blades are provided with vertical ribs that guide the ice blocks toward the cutter. The crushing conditions for ice blocks are changed between the reverse side and the reverse side to selectively obtain crushed ice pieces of different roughness.

However, although the escape of ice blocks from the crushing vines is slightly different between the forward rotation side and the reverse rotation side, there is a difference in the size of the gap where the crushed ice pieces fall that each fixed blade forms on the forward rotation side and the reverse rotation side of the hopper outlet. Instead, crushed ice pieces reaching the same size are dropped on both the forward and reverse rotation sides, so even on the side where the escape of ice cubes is strongly regulated, ice pieces often fall until they are broken into fine pieces. There is little difference in the crushed ice pieces obtained between the forward rotation side and the reverse rotation side.

The purpose of this idea is to be able to reliably change the roughness of crushed ice pieces between the forward and reverse rotation sides without complicating the operation. A crushing cutter is provided at the outlet of the hopper, and the falling ice piece roughness limiting member is installed at the forward rotation side outlet of the crushing cutter and the crushing cutter reverse rotation side outlet of the hopper at the position where the falling ice piece roughness limiting member passes. The ice crusher is characterized in that an ice piece falling gap is formed between the limiting member and the peripheral wall of the hopper outlet part, and the size of the ice piece falling gap is made different between the normal rotation side and the reverse rotation side.

First of all, the embodiment shown in FIGS. 1 to 3 will be described. Reference numeral 1 denotes a main body, which has a hopper 2 at its upper part into which ice cubes are thrown, and an outlet 3 of the hopper 2. A falling ice piece roughness limiting member 5 that divides the falling ice piece falling gap 4 with an appropriate width, and a crushing cutter 6 that crushes the ice block in the hopper 2 between the falling ice piece roughness limiting member 5 and the falling ice piece roughness limiting member 5 are provided. There is. The crushing ivy 6 is connected to the hopper outlet part 3
Several radial cutter plates 8 are attached at regular intervals to a rotating shaft 7 installed horizontally in the center of the outlet section 3 so as to rotate together with a length extending to the vicinity of the peripheral wall of the outlet section 3. The cutter plate 8 has normal rotation side crushing teeth 8a that crush ice blocks between it and the normal rotation side falling ice flake roughness limiting portion 5a on one side of the rotating shaft 7 during normal rotation in the direction of arrow a. When reversing in the direction of arrow b, the rotating shaft 7
It has reverse side crushing teeth 8b for crushing ice chunks between it and the reverse side falling ice piece roughness limiting portion 5b on the other side.

The member 5 having the falling ice flake roughness limiting portions 5a, 5b on the normal rotation side and the reverse rotation side has the above-mentioned portions 5a, 5.
A spacer 9a is made of a single cutter plate with upward crushing teeth 5c and 5d formed on the cutter plate 8, and is mounted on the rotating shaft 7 between the cutter plates 8 and has a mounting hole 5e at the boundary between each portion 5a and 5b. , 9b, and are rotatably fitted into the outer circumferential groove 9c between the cutter plates 8 and the cutter plates 8, and are attached to the rotating shaft 7 alternately to form a cutter unit. 9d is another spacer. Katsuta board 8
The mounting hole 8c formed in the center is directly fitted to the rotating shaft 7 so as to rotate together with the spacers 9a, 9b, and 9d. This integrally rotating structure can be easily obtained by attaching the cutter plate 8 or spacers 9a, 9b, 9d to the non-circular cross section of the rotating shaft 7.

The rotation shaft 7 is connected to a speed reduction mechanism 1 consisting of gears 12 and 13 by a drive shaft 11 having a manual handle 10.
4, and rotates forward or reverse according to the direction of rotation of the drive shaft 11 by the manual handle 10. The handle 10 is fitted onto a non-circular cross section 11a at one end of the drive shaft 11 and is prevented from coming off with a screw 15 so that the drive shaft 11 can selectively and reliably rotate in both forward and reverse directions. 1
6 is a screw hidden plate.

On the other hand, the main body 1 includes a hopper 2 and a cylindrical body 1.
7 is formed separately, and the hopper 2 is fitted into the body part 17 from above and integrated with the screw 18, and the hopper 2 is connected to the inner sole 20 of the body part 17, which has an opening 19 for dropping crushed ice pieces. In between, the rotating shaft 7
The bearings 21 and 22 of the drive shaft 11 are clamped and held. In addition, the outlet part 3 of the hopper 2 and the inner sole 2
Vertical groove 2 facing opposite crushed ice piece falling port 19 of 0
The ends of the falling ice piece roughness limiting member 5 are sandwiched between 3 and 24 so that the member 5 is fixed without interfering with the rotation of the crushing cutter 6.

On the bottom plate 25 attached to the lower end of the body 17,
Inlet/outlet opening 2 opened in the lower front half of the body 17
The ice receiver 27 to be loaded and unloaded from 6 is received,
It is located directly below the crushed ice piece falling port 19. 28
is the lid of Hopper 2.

The width adjusting plates 29, 29 are applied to both sides of the falling ice piece roughness limiting portion 5b on the reverse side of the falling ice piece roughness limiting member 5 and riveted 30, and the falling ice piece roughness limiting portion 5a on the normal rotation side is fixed with rivets. The plane width of the falling ice flake roughness limiting portion 5b on the reverse side is made larger than the plane width. As a result, the width dimension of the ice piece falling gap 4a on the normal rotation side and the ice piece falling gap 4b on the reverse side of the ice piece falling gap 4 is different. In other words, the ice piece falling gap 4b on the reverse rotation side is larger than the ice piece falling gap 4a on the forward rotation side.
It is narrower than the

When an ice block is put into the hopper 2 and the crushing cutter 6 is rotated, if the rotation is normal rotation in the direction of the arrow a, each cutting plate 8 of the crushing cutter 6 passes through the ice piece fall gap 4b on the reverse side and lowers the hopper 2. Hopper 2
While pushing the ice cubes inside towards the normal rotation side ice piece fall gap 4a side, approach the normal rotation side falling ice piece roughness restriction part 5a from above, and exit to the bottom of the hopper 2 through the normal rotation side ice piece fall gap 4a. , the ice block that cannot fall because it is larger than the normal rotation side falling ice piece falling gap 4a and is placed on the normal rotation side falling ice piece roughness restriction part 5a is caught between it and the same restriction part 5a and crushed. Teeth 8a, 5
C. Crush. Further, when the rotation is a reversal in the direction of arrow b, each cutter plate 8 of the crusher cutter 6 moves the ice block in the hopper 2 between it and the falling ice piece roughness limiting portion 5b on the reverse side. and crushed by the crushing teeth 8b and 5d.

Therefore, depending on whether the crushing cutter 6 rotates in the normal or reverse direction, crushing is performed in either the normal rotation side falling ice flake roughness limiting portion 5a or the reverse rotation side falling ice flake roughness limiting portion 5b; When crushing is performed in the same part 5a, ice pieces with a particle size smaller than the width of the ice piece falling gap 4a fall downward, and the ice pieces fall downward in the other part 5b.
When crushing is performed in the same portion 5b, ice pieces having a particle size smaller than the width of the ice piece fall gap 4b fall downward. As a result, the crushing cutter 6 is rotated in the normal direction, and the falling ice piece roughness limit portion 5a on the normal rotation side is rotated.
The particle size of the crushed ice pieces obtained is different depending on whether the crushing cutter 6 is rotated forward or backward, and when it is crushed on the reverse side falling ice piece roughness limiting portion 5b. The particle size of the resulting crushed ice pieces can be selected.

In particular, ice blocks are crushed by the falling ice flake roughness limiting portions 5a, 5b on the forward and reverse sides and the cutter plate 8, the cutter plate 8 having a length extending to the vicinity of the peripheral wall of the outlet portion 3; Since the falling ice pieces pass through the entire area of each ice piece falling gap 4a, 4b in each of the falling ice piece roughness limiting portions on the normal rotation side and reverse rotation side, the falling ice piece roughness limiting portions 5a on each of the normal rotation side and reverse rotation side are made. , 5b, ice blocks of different roughness can be reliably crushed with different roughnesses due to the difference in the gap width of each ice piece falling gap 4a, 4b without any ice blocks escaping throughout the crushing part.

Further, in the above embodiment, the number of teeth of the crushing teeth 5c of the normal rotation side limiting portion 5a of the falling ice flake roughness limiting member 5 is as follows:
The number of teeth is smaller than that of the crushing teeth 5d of the reverse rotation side limiting portion 5b, so that the crushing cutter is crushed more roughly during normal rotation than during reverse rotation.

In place of the screw hidden plate 16 of the handle 10,
A cap 43 having an elastic tube 42 provided with a groove 41 as shown in FIGS. 4 and 5,
If the cylinder 42 is elastically fitted into the inner periphery of the screw-fastening recess 44 of the handle 10 and can be installed removably, the installation process becomes easier, and when the handle 10 is to be removed for storage, etc., the cap can be easily removed. This can be easily done by removing screw 43 and pulling out screw 15.

In FIG. 6, a threaded portion 11b is formed at the tip of the non-circular cross-sectional portion 11a of the drive shaft 11, and the handle 10 is prevented from coming off by a nut 51 that is screwed into the threaded portion 11b.

As mentioned above, the method of sandwiching an ice block between two members and biting the opposing crushing teeth of each member to crush the ice block has a relatively large resistance to crushing the ice block, which is necessary due to the action of the speed reduction mechanism 14. Although the operating force is greatly reduced, it is not possible for the operator to position the main body 1 on the lower side in FIG. However, it is not easy to pull the handle 10 in the direction opposite to the arrow c. Therefore, as shown in FIG.
1, 62, and attach the handle 11 to one end of the square shaft part 11c as shown by the solid line, or the other end to the corner shaft part 1 as shown by the imaginary line.
1d, if the handle 10 can be attached selectively during reverse operation, if the handle 10 is attached as shown in the imaginary line and the operator positions it on the opposite side of the main body 1, the operation will be the same as during forward rotation. The crushing vine can be easily reversed by pushing and turning.

The difficulty of the operation is explained based on the case of a right-handed operator, and the situation is reversed for a left-handed operator.
There is no change in the advantages of the above-mentioned replacement of the handle 10, and the handle 10 can be easily pushed and turned in both the virtual line state during forward rotation and the solid line state during reverse rotation.

In FIG. 7, each corner shaft portion 11 of the drive shaft 11 is provided in the mounting hole 63 of the handle 10 to the drive shaft 11.
A spring ring 65 is attached which elastically engages with the engagement recess 64 provided in the recess 64.
Due to the elastic engagement between the handle 1 and the spring ring 65, the handle 1
0 is removably stabilized in the attached state as shown by the solid line or the imaginary line. 66 is an annular groove holding the spring ring 65.

As described above, as long as the forward and reverse rotations are easy to operate, even if the rotary shaft 8 is directly rotated by the handle 10, the operation will not be difficult.

8 and 9, a width adjusting plate 71 with crushing teeth 5d is riveted 30 to both sides of the falling ice flake roughness limiting portion 5b on the reverse side of the falling ice flake roughness limiting member 5, In FIG. 10, a width adjusting plate 71 with crushing teeth 5d is formed in the same shape as the member 5 from which the falling ice flake roughness limiting portion 5a on the normal rotation side is removed, and the width adjusting plate 71 is inserted into the hopper exit portion together with the member 5. It is designed to be retained. 72 is a mounting hole.

11 and 12 show that the crushing teeth 5d of the falling ice flake roughness limiting portion 5b on the reverse side are bent and the same portion 5 is
The plane width dimension of b is increased, and the width dimension of the ice piece falling gap 4b on the reverse rotation side formed between the portions 5b is made smaller than that on the normal rotation side. The crushing teeth 5d may be bent alternately in opposite directions, or may be bent so that the tips of the teeth face directly upward as shown in FIG.

14 and 15 show the crushing teeth 5d formed on the width adjustment plate 71 being bent so that one width adjustment plate 71 can increase the width by two thicknesses. .

16 and 17 show a structure in which both side width adjustment plates 81 are integrated by a bridge portion 81a between two ends of the upper edge, and the bridge portion 81a is on the reverse side of the falling ice flake roughness limiting member 5. By fitting the width adjustment plate 81 to a degree that it can be detached and suspended over the restriction portion 5b, and replacing the width adjustment plate 81 with one having a different thickness, the particle size of the resulting crushed ice pieces can be changed to two or more types. Allowing you to choose. Reference numeral 82 is a concave portion formed in a portion of the member 5 that fits into the bridge portion 81a, and serves to prevent the width adjustment plate 81 from shifting. The width adjusting plate 81 is connected to the member 5 as shown in FIG.
Even if the ice block is simply fitted to the bottom of the width adjustment plate 81, there is no need for it to fall off during crushing because the ice block being crushed is pressed from above.However, as shown in FIG. Falling off can be actively prevented by forming an engaging portion 81b that elastically engages with the edge.

In FIG. 19, when the crushing cutter is electrically driven by a motor 91, it is rotated forward or reverse by switching a switch 92. Although the figure shows the case where the simplest DC power source 93 is used, it is of course applicable to the case where an AC power source is used, and the rotation direction can also be mechanically switched. All of these are already known and will not be explained here.

The falling ice piece roughness limiting member 5 may be a simple bar or plate without crushing teeth, ignoring the difficulty of crushing ice blocks, or if coarse crushed ice pieces are desired, crushing is excessive. In order to prevent this from happening, it is even more advantageous to use a member that does not have crushing teeth.

According to this invention, the size of the ice piece falling gap created by the falling ice piece roughness limiting member is different between the normal rotation side and the reverse rotation side of the crushing cutter, and the roughness of the falling ice pieces is forcibly limited. The roughness can be reliably changed between the forward rotation side and the reverse rotation side.
