Abstract

PURPOSE:To increase or decrease an ice piece passing area at an ice piece outlet port and facilitate a making of crush ices of some kinds having different sizes to each other by a method wherein a set position of an ice block feeding cylinder having an ice piece passing part opposed to or not opposed to an ice piece outlet port of a case against the case is varied. CONSTITUTION:In order to make crush ices, i.e., ice pieces, the ice block is fed from an ice block feeding cylinder 61 of a case 31, thereafter a lid 75 is covered on it to push it and an ice block feeding cylinder 61 is fixed and at the same time a switch 22 is turned on to rotate an electric motor 12. Then, a crushing member 81 connected to a rotating shaft 13 of the electric motor 12 is rotated at a high speed only for a period in which the lid 75 is being pressed, the ice block is broken into ice pieces. The ice pieces pass through a clearance G between a lower end of the ice block feeding cylinder 61 and a disk part 82 and the ice pieces are discharged to an ice piece taking- out passage 45. In this case, in order to reduce a roughness of the ice pieces, for example, the ice piece passing part 69 of the ice block feeding cylinder 61 is displaced from an ice piece outlet of the case 31 and at the same time a lower cylinder part 68 is opposed against the ice piece outlet to close a part of it.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric ice crusher that crushes ice cubes produced in a freezer or the like into small pieces of ice.

0002

2. Description of the Related Art An electric ice crusher disclosed in Japanese Unexamined Patent Publication No. 2-130370 is known. This ice crusher includes a bottomed cylindrical case with an open top, a rotating shaft that is provided through the bottom wall of the case and rotated by the power of an electric motor.
It is attached to a rotating shaft with an ice piece outlet gap formed between an ice block input cylinder disposed in the case and the lower end of this input cylinder,
The crushing body has a crushing protrusion on the upper surface.

When the electric motor is operated in this ice crusher, the crushing protrusion of the crushing body rotated together with the rotating shaft collides with the ice cubes thrown into the ice cube charging cylinder, crushing them and producing ice pieces (crushed ice). Ice pieces that are smaller than the ice piece outlet gap can be discharged from the ice cube input cylinder through this gap by the centrifugal force of the crushed body, and can be stored at the bottom of the case.

[0004] By the way, in the technique described in the above publication, the size of the ice pieces is determined by the ice piece outlet gap, but since this size cannot be changed, only one size of crushed ice can be obtained. . Therefore, the present applicant removably attaches an adjusting ring to the lower end of the ice cube input tube, and by attaching this ring, the ice piece outlet gap is made smaller, and by removing the ring, the ice piece outlet gap is made larger. We proposed an ice crusher that can make crushed ice of different sizes.

[0005]

[Problems to be Solved by the Invention] However, in the configuration in which the size of the ice cubes is changed using the adjustment ring as described above, since the adjustment ring is required, the number of parts is large, and the adjustment ring is difficult to adjust to the size of the ice cubes. There is a problem in that it requires time and effort to attach and detach from the input tube, making it inconvenient to handle.

[0006] An object of the present invention is to obtain an ice crusher with a simple structure that can be easily made by arbitrarily selecting any of a plurality of types of crushed ice of different sizes.

[0007]

[Means for Solving the Problems] In order to achieve the above object, an ice crusher of the present invention has a cylindrical wall portion having an ice chip outlet, a bottom wall connected to the cylindrical wall portion, and a case with an open upper end; a lower cylindrical part with both upper and lower ends open and fitted into the cylindrical wall part to open a part of the ice chip outlet; an ice block insertion cylinder that is detachably housed in the case by selecting one of the set positions thereof; and at least one ice block insertion tube is formed in the lower cylindrical part and is arranged facing or not facing the ice piece outlet. an ice piece passing section that increases the ice piece passing area of the ice piece outlet when facing each other; a rotating shaft that is arranged on an axis passing through the center of the bottom wall and rotated by the power of an electric motor; An ice piece passage connected to the upper part of the shaft and disposed inside the cylindrical wall part and communicating with the ice piece outlet is formed between the cylindrical wall part, the bottom wall, and the lower cylindrical part. A crushing body having an upward crushing protrusion protruding from a disk portion, and an ice piece removal passageway body having one end connected to the ice piece outlet and extending in a tangential direction of the cylindrical wall portion. This is what I did.

In addition, in order to prevent the size of the crushed ice produced from changing inadvertently despite the simple structure, a switch operating rod for operating a switch for starting and stopping the electric motor is mounted up and down in the case. an operation rod cover portion that is movably attached and that protrudes inside the case and covers the operation rod is provided integrally with the case;
It is preferable that a plurality of recesses, which are detachably engaged with the cover part, are provided on the circumference of the ice block throwing cylinder.

[0009]

[Operation] In the invention as claimed in claim 1, when the crushing body is rotated by the power of the electric motor, the crushing protrusion crushes the ice cubes thrown into the ice cube throwing cylinder into crushed ice, and this ice is crushed by centrifugal force or the like. Ice chips are supplied to the aisle. At the same time, the crushed ice in the ice piece passage is successively discharged from the ice piece outlet in the tangential direction of the cylindrical wall by wind passing through this passage. Therefore, crushed ice is taken out from the ice piece removal passage. Since the ice cube charging tube can be stored by rotating it in its circumferential direction and positioning it in one of the set positions of the case, the ice piece passage formed in the lower cylindrical part of the ice cube loading tube can be connected to the ice piece outlet. They can be selectively placed in positions that are not facing each other or in positions that are facing each other.

[0010] Therefore, when the ice cube charging cylinder is stored in the case at a set position where the ice chip passing portion does not face the ice chip outlet, the lower cylindrical portion of the ice cube charging cylinder opens a part of the ice chip outlet, for example, only the lower side. let In operation under this set condition, the size of crushed ice passing through the ice piece outlet is limited to a size smaller than the gap between the disk part of the crusher and the lower end of the lower cylindrical part of the ice cube input tube. do. Furthermore, when the ice cube charging cylinder is stored in the case at the set position where the ice piece passage part faces the ice piece outlet, the ice piece outlet becomes smaller than when the ice piece passage part does not face the ice piece outlet as described above. The opening is large, for example, extending widely between the disc part of the crushing body and the upper end of the ice piece passage part. In operation under this set state, the size of crushed ice is not limited by the gap between the lower cylindrical part and the lower end, and larger crushed ice can be passed through the ice piece outlet.

[0011] According to the invention of claim 1, by changing the direction of the ice cube feeding tube and storing it in the case, the area through which the ice pieces pass through the ice piece outlet can be increased or decreased, and the size can be increased. You can make different types of crushed ice.

[0012] According to the second aspect of the invention, the concave portion of the ice block insertion cylinder is engaged with the operation rod cover portion of the switch operation rod that is integrally formed with the case and starts and stops the electric motor. By doing so, the ice block charging cylinder can be positioned in a set position where the ice chip passing portion does not face the ice chip outlet, or in a set position where it faces the ice chip outlet, and the engagement prevents the ice block charging cylinder from inadvertently rotating during operation. Can be done.

[0013]

It is provided so that it can be moved up and down by passing through a guide hole provided in the switch mounting plate 21. A coil spring 25 is provided between the switch pressing member 23 and the switch mounting plate 21 by wrapping the lower part of the shaft portion 23b, and this spring 25 always urges the switch pressing member 23 upward. The switch pressing portion 23 is spaced above the switch 22. The upper end of the shaft portion 23b is inserted into a cylindrical portion 26 (see FIG. 16) formed on the upper surface of the main body 11, and is exposed to the outside of the main body 11.

A ventilation hole is provided in the bottom plate (not shown) that closes the bottom surface of the main body 11, and the air that passes through it flows around the electric motor 12 and then exits from the upper end opening covered with the draining disk 15. It is designed to flow upward from the main body 11. In addition, the front part of the main body 11 is shown in FIGS. 15 and 16.
, and a concave curved surface 27 recessed inside the main body 11, as shown in FIG.

A synthetic resin case 31 shown in FIGS. 7 to 9 is removably attached to the main body 11. As shown in FIGS. This case 31 has a cylindrical outer wall portion 32 that is open at both upper and lower ends.
A cylindrical wall part 34 is integrally connected to the inner surface of this wall part 32 via a tapered wall part 33, a horizontal bottom wall 35 is integrally connected to the lower end of this wall part 34, and this bottom wall. The fitting wall 36 has a cylindrical shape and integrally projects from the lower surface of the periphery of the fitting wall 35 facing downward.

The lower edge of the outer wall portion 32 is placed on a step portion 11b (see FIG. 5) formed on the upper part of the main body 11 and extending in the circumferential direction. A cylindrical wall 34 , a bottom wall 35 , and a fitting wall 36 are arranged inside the outer wall 32 . An ice piece outlet 37 (see FIGS. 1 and 2) is formed in a part of the cylindrical wall portion 34. A through hole 38 is provided in the center of the bottom wall 35.
(See FIGS. 1, 2, 8, and 9) is formed, and the upper part of the drive coupling 14 is inserted into this through hole 38. Note that the reference numeral 42 shown in FIG. 8 is a rib-shaped shielding wall that extends horizontally to the upper end of the ice piece outlet 37 at the same height as the lower end of the tapered wall portion 33 . This wall 42 is provided to prevent crushed ice from blowing upward at the ice piece outlet 37 section.

The fitting wall 36 is fitted into the protruding portion 11a of the main body 11, and has a pair of mounting claws 39 facing each other in the radial direction, as shown in FIG. The pawl 39 engages and disengages from the engagement recess 18 and is formed to be elastically deformable, and is provided with an engagement groove 40 that engages and disengages from the engagement rib 19. In addition, in FIG. 9, 41 is a groove for enabling elastic deformation of the mounting claw 39.

Therefore, the outer wall portion 32 is brought into contact with the stepped portion 11b, and the mounting claw 39 is placed in the recess 1 of the protruding portion 11a.
6, the fitting wall 36 is inserted into the protrusion 11a.
After fitting, the case 31 is attached to the main body 11 by turning the case 31 in the direction of arrow A in FIG. The case 31 is removed. When the case 31 is attached to the main body 11, the attachment claw 39 is engaged with the engagement recess 18, and the groove 41 of this claw 39 is engaged with the engagement rib 19, as shown in FIG. The movement of the case 31 in the circumferential direction is stopped, and the vertical movement of the case 31 is also stopped by the stepped portion 11b and the holding piece 7.

[0021] The case 31 is integrally formed with an ice piece removal passage 45 in the shape of, for example, a rectangular cylinder, which is open at both ends. The passage body 45 is provided so as to extend in the tangential direction of the cylindrical wall portion 34, with its one end opening integrally connected to the ice piece outlet 37. Preferably, as shown in FIGS. 1 and 2, one of the opposing vertical side walls 46 and 47 of the ice piece removal passage 45 is formed with a bent portion between it and the cylindrical wall 34. It is preferable to extend them in the tangential direction of the cylindrical wall portion 34 so as to extend them smoothly and continuously. The bottom wall portion 48 of the ice piece removal passage body 45 is inclined so as to gradually descend from the ice piece outlet 37 toward an ice piece removal port body to be described later. The bottom wall 35 is provided with an inclined surface 35a that is flush with and continuous with the bottom wall portion 48. In addition, 4 in the figure
Reference numeral 9 denotes a passage cover part which is integrated with the case 31 and the ice piece removal passage body 45, and as shown in FIG.
This cylindrical body 45 is covered from above.

As shown in FIGS. 3 to 6, an ice piece outlet body 51 made of synthetic resin is connected to the other end of the ice piece outlet passage 45. As shown in FIGS. The mouth body 51 has a cylindrical shape with an open lower end, and a connection port 52 formed on the upper side surface is connected to the other end opening of the ice piece removal passage body 45 (see FIGS. 1 and 2). As shown in FIG. 5, a scraper 5 that is slidable along the inner periphery of the ice piece removal port 51 is provided in the ice piece removal port 51.
3 is housed therein, and an operating knob 54 for rotating the scraper 53 is attached to the upper side of the ice piece outlet body 51. The scraper 53 and the operation knob 54 are given an initial tension by a torsion coil spring 55, and this force causes the scraper 53 to be normally placed so as to avoid the inner surface of the connection port 52 and the ice piece outlet body 51 that directly faces it. It is now possible to do so. The scraper 53 is reciprocally rotated by an operation knob 54 and a torsion coil spring 55, and is used to scrape off ice pieces (crushed ice) that have adhered to the inner peripheral surface of the ice piece outlet body 51 due to the rotation. used.

As shown in FIG. 8, the upper inner peripheral surface of the case 31 is provided with a plurality of ribs 56 extending in the vertical direction and the operating rod cover portion 5.
7 are integrally formed. The upper end of the rib 56 is located at a lower position than the upper end of the case 31. The upper end of the operating rod cover part 57 protruding inward from the case 31 is lower than the upper end of the case 31 but higher than the upper end of the rib 56. The upper end of the operating rod cover portion 57 is open.

As shown in FIGS. 1, 2, 5, and 6, a switch operating rod 58 made of synthetic resin is attached to the case 31 for operating the switch 22. This operating rod 58 is arranged to be movable in the vertical direction between the outer wall portion 32 and the operating rod cover portion 57, and its lower end portion is inserted through a spring receiving plate 59 fixed to the case 31. A coil spring 60 is sandwiched between this plate 59 and the switch operating rod 58.
The switch operating rod 58 is always urged upward by the spring 60, and its upper end is exposed to the upper end opening of the operating rod cover portion 57.

With the case 31 attached to the main body 11, the lower end of the switch operating rod 58 is close to or in contact with the upper end of the shaft portion 23b of the switch pressing member 23. Therefore, when the switch operating rod 58 is pressed down, the switch pressing member 23 is also pressed down, so that the switch pressing part 23a presses the switch 22, and this switch 22 is turned on. As the force disappears, the coil springs 25, 60
The switch pressing member 23 and the switch operating rod 58
are pushed up, respectively, and the switch 22 is turned off.

[0026] Inside the case 31, an ice cube charging cylinder 61 made of synthetic resin is removably housed. This input tube 61 is
As shown in FIGS. 3, 12, etc., it is formed from a cylinder main body 62 and a main body cover 63.

The cylinder body 62 is open at both upper and lower ends. A flange 64 integrally extends outward from the upper outer peripheral surface of the cylinder body 62. This flange 64 is the rib 5
6, which determines the depth of insertion into the case 31. Projections 64a are integrally provided at multiple locations on the upper surface of the flange 64, and the flange 64
A first recess 65 and a second recess 66 that are selectively fitted into the operating rod cover portion 57 are formed in the recess 65 . Furthermore, a V-shaped index groove 67 (see FIGS. 3 and 11) is formed in the upper edge of the cylinder body 62. By aligning the index groove 67 with the mark provided on the outer surface of the opening edge of the outer wall portion 32, the first recess 65 or the second recess 66 is aligned with the operating rod cover portion 57.
are aligned.

The cylindrical body 62 has a lower cylindrical portion 68 at its lower portion that overlaps and fits inside the cylindrical wall portion 34 . This cylindrical portion 68 overlaps the ice piece outlet 37 so as to be inserted from above, for example, the ice piece outlet 37.
The upper half of 7 is closed off from the inner peripheral side of the cylindrical wall portion 34. The lower cylindrical part 68 has an ice piece passage part 6 that faces or does not face the ice piece outlet 37 depending on the rotation of the ice block input cylinder 61.
9 is formed. The ice piece passage portion 69 is formed by a horizontally long rectangular notch, opens at the lower end of the lower cylindrical portion 68, and has a width B larger than the width of the ice piece outlet 37.

The ice piece passing portion 69 is configured as shown in FIG. When the first recess 65 is fitted to the operating rod cover part 53 and the ice block input tube 61 is stored and set in the second set position of the case 31, As shown in FIG. 1, it is arranged at a position opposite to the ice piece outlet 37. When this ice piece passage part 69 faces the ice piece outlet 37, the upper edge of the ice piece passage part 69 (the edge facing the opening) is located at the same height as the upper edge of the ice piece outlet 37, and the ice piece For example, the single outlet 37 is configured to be fully opened.

The main body cover portion 63 is connected to the cylinder body 62 so as to be flush with the upper circumferential surface of the cylinder body 62, and has an input port 70 on its upper surface. The input port 70 has a small diameter that makes it easy to input ice cubes, but makes it difficult for a hand to be accidentally inserted into the cylinder body 62. Note that the ice block charging tube 61 may have a configuration in which the main body cover portion 63 is omitted.

A lid 75 made of synthetic resin that covers the ice cube charging tube 61 is detachably attached to the upper surface of the case 31. The lid 75 has a hemispherical shape and integrally has a circular downward projecting edge 76 at its lower end. Therefore, lid 7
5 can be attached to the upper surface of the case 31 in any orientation. The downward projecting edge 76 is inserted into an annular gap formed between the upper edge of the outer wall 32 of the case 31 and the upper part of the flange 64 of the cylinder body 62, and is inserted between the flange 64 and the rib 56 from above and below. It is held in place and abuts against the upper end of the switch operating rod 58 to push the rod 58 down.

Therefore, when the lid 75 is placed over the case 31, the switch operating rod 58 side is slightly raised and the lid 75 is provided in a slightly slanted state, as shown in FIG. Then, by pushing the lid 75 downward from this state, the downward projecting edge 76 clamps the flange 64 between the rib 56 and the ice cube charging cylinder 61 is prevented from moving upward, as shown in FIG. At the same time, the switch operating rod 58 is pushed down, and the switch 22 is turned on as described above. Furthermore, when the pressure on the lid 75 is released, the state shown in FIG. 5 is restored and the switch 22 is turned off.
Electric motor 12 is stopped.

The diameter and height of the lid 75 are such that when the lid 75 is gripped from above, the gripping fingers cannot reach the case 31, or even if the fingers touch the case 31, the lid 75 cannot be grasped and lifted up. It is set to such a size that it cannot be used. This makes it impossible to carry the entire ice crusher by grasping the lid 75 from above during use.
Even if the carrying operation is attempted when the case 31 is not fixed, the case 31 can be prevented from accidentally coming off from the main body 11.

[0034] The drive coupling 14 has a crushed body 81.
are removably fitted and attached. The crushing body 81 includes a disk portion 82, a driven coupling 83, a crushing protrusion 84,
85, and a scraping protrusion 86.

Disc portion 8 disposed inside the cylindrical wall portion 34
2 has a diameter slightly larger than the diameter of the lower end opening of the lower cylindrical portion 68, and has a predetermined gap G (for example, 3 m) between the lower end opening and the lower end opening.
m, see FIGS. 5 and 6). Further, the dimension H between the circumferential portion of the disc portion 82 and the upper edge of the ice piece passing portion 69 is, for example, 15 mm. Between the disk part 82, the cylindrical wall part 34, the bottom wall 35, and the lower cylindrical part 68,
An ice piece passage 87 is formed. This passage 87 surrounds the circumference of the disc portion 82 and is communicated with the ice piece outlet 37.

The driven coupling 83 is formed of a cylindrical portion integrally projecting from the lower surface of the center of the disc portion 82, and this coupling 83 is removably fitted to and connected to the drive coupling 14. and can rotate together with the drive coupling 14 in the connected state. A crushing metal fitting 88 is riveted to the upper surface of the disc portion 82. A crushing protrusion 84 is bent upward at one end of the metal fitting 88, and a crushing protrusion 85 is bent at the other end. The crushing protrusion 84 has a rib shape and extends in the radial direction of the disk portion 82, and the crushing protrusion 85 is provided along the direction intersecting the length direction of the crushing fitting 84, and It stands up higher than the protrusion 84.

The scraping protrusions 86 are integrally provided at a plurality of locations on the lower surface of the periphery of the disc portion 82 . These protrusions 86 are rib-shaped and extend in the direction of deformation of the disc portion 82, and protrude into the ice piece passage 87.

As shown in FIG. 4, the disc portion 82 is provided with a pair of holes 89 located on both sides of the crushing fitting 88. These holes 89 are for inserting and hooking fingers when attaching and detaching the crushing body 81. The edge of each hole 89 has a relatively large tapered surface 90 facing upward. By providing the tapered surface 90, crushed crushed ice is thrown upward and the passage of crushed ice through the hole 89 is minimized.

Next, the procedure for making crushed ice will be explained. First, as shown in FIG. 15, place the ice piece receiving container 91 below the ice piece outlet body 51 and remove the lid 75. Input the appropriate number of liquids into the tank through the input port 70. Next, after covering the lid 75 as shown in FIG. 5, by pushing the lid 75 downward as shown in FIG.
1 is fixed, and the switch 22 is turned on to start the electric motor 12.

Then, while the lid 75 is being pressed by hand, the crushing body 8 connected to the rotating shaft 13 of the electric motor 12
1 is rotated at high speed, its crushing protrusions 84, 85
repeatedly collides with ice blocks. This collision shatters the ice blocks one after another into small pieces of ice (crushed ice).
The centrifugal force and the crushing protrusions 84 and 85 cause the disk portion 82 to be moved toward the outer side of the circumference. And the ice block insertion tube 6
The crushed ice, which has become smaller than the gap G between the lower end of 1 and the disc part 82, is supplied to the ice piece passage 87 through the gap G, and then the scraping protrusion moves within this ice piece passage 87. 86 and is vigorously discharged from the ice piece outlet 37 into the ice piece removal passageway 45. Therefore, the crushed ice passes from the ice piece passage 87 through the ice piece outlet body 51, and the ice piece receiving container 9 disposed below the ice piece outlet body 51.
1 are taken out one after another. Therefore, case 3
The crushed ice made in 1 is transferred to Case 3 one by one.
It is easy to use because there is no need to take it out from the inside.

When making a large amount of ice cubes, after taking out the ice cubes, open the lid 75 to stop the operation of the electric motor 12, then put the ice cubes back in, and repeat the above steps as many times as necessary. Just repeat.

In order to obtain crushed ice with small roughness when making crushed ice in the above manner, the first recess 65 of the ice block charging tube 61 is fitted into the operating rod cover section 57, and the ice block 61 is is stored in the first set position of the case 31,
Just follow the steps mentioned above. In this case, as shown in FIG.
The lower cylindrical portion 68 faces the ice piece outlet 37 and blocks a portion (upper portion) thereof. Therefore, the size of crushed ice passing through the ice piece outlet 37 is limited to the size of the gap G or less.

In order to obtain crushed ice with large roughness, the second recess 66 of the ice block charging cylinder 61 is fitted into the operating rod cover 57, and the second recess 66 of the ice block charging cylinder 61 is inserted into the second recess of the case 31.
Just store it in the set position and carry out the procedure described above. In this case, as shown in FIG. 1, the ice piece passage portion 69 of the ice block input tube 61 is positioned opposite the ice piece outlet 37, and the entire outlet 37 is opened. Therefore, without being restricted by the gap G, crushed ice of the size of the opening of the portion of the ice piece outlet 37 above the disk portion 82, that is, ice pieces larger than the ice pieces passing through the gap G, can be collected. Single exit 3
7 and can be removed.

By changing the set position of the ice block input tube 61 with respect to the case 31 in this way, the size of the area through which crushed ice passes through the ice piece outlet 37 can be adjusted, thereby eliminating the need for special adjustment parts and making it simple. It is easy to use because it does not require the effort of attaching and detaching adjustment parts, and it is easy to change the set position of the ice block throwing cylinder 61.

The setting position of the ice block charging cylinder 61 can be changed by using the switch operating rod 5 that starts and stops the electric motor 12.
8, and insert the first recess 65 into it.
Alternatively, since it is realized by engaging the second recess 66, the structure is simple. Moreover, due to these engagements,
Since the ice block feeding cylinder 61 can be positioned in a position where the ice piece passing portion 69 does not face the ice piece outlet 37, or in a position where it faces the ice piece outlet 37, the ice block feeding cylinder 61 does not rotate inadvertently during operation, and the amount of crushed ice that is produced is reduced. It is possible to prevent the size from changing inadvertently.

Furthermore, since the concave curved surface 27 is provided on the front part of the main body 11, the positions of the ice piece outlet body 51 and the cylindrical wall part 34 are determined in relation to the arrangement space of the ice piece receiving container 91, as shown in FIG. It is possible to shorten the ice piece removal passage body 45 that connects the ice pieces, and also to reduce the maximum length E from the main body 11 to the ice piece removal port body 51, thereby achieving overall miniaturization. Incidentally, when the main body 11 is cylindrical without the concave curved surface 27 as shown in FIG. big. In particular, by making the ice piece removal passage 45 shorter, the attenuation of the kinetic energy of the crushed ice released from the ice piece outlet 37 can be reduced, and smooth ice piece removal can be realized. Incidentally, if the ice piece removal passage 45 is long, there is a high possibility that the kinetic energy of the crushed ice that attempts to pass through it will be attenuated, causing the ice to fall into the ice piece removal passage 45, resulting in defective ice removal. .

Note that the present invention is not limited to the above embodiment. For example, a mixer main body having a built-in electric mixer motor may be used. In addition, the lower cylindrical part of the ice cube input tube may be provided with a plurality of ice piece passage parts having different depths in succession, and in that case, the roughness of the crushed ice can be changed to three or more levels. can. Furthermore, the shape of the ice piece passing portion is not limited to a square, but may be triangular.

[0048]

[Effects of the Invention] Since the present invention is constructed as described above, it has the following effects.

In the ice crusher of the first aspect, by changing the set position in the case of the ice cube charging cylinder having the ice piece passing portion facing or not facing the ice piece outlet of the case, the ice at the ice piece outlet is removed. Since the structure allows the area through which the pieces pass to be increased or decreased, it is possible to easily create crushed ice selected from among multiple types of crushed ice of different sizes without the need to attach or detach an adjustment ring to the ice cube charging tube. be able to.

[0050] In the ice crusher of the second aspect, since the ice cube charging cylinder can be positioned in a position where the ice chip passage portion does not face the ice chip outlet or in a position where it faces the ice chip outlet, the ice cube charging cylinder does not rotate inadvertently during operation. This prevents the size of the crushed ice produced from changing inadvertently, and the detent is formed integrally with the case and utilizes the operation rod cover of the switch operation rod that starts and stops the electric motor. The structure is simple because it was realized in a simple manner.
