Description

Description: TECHNICAL FIELD The present invention relates to an electric ice crusher that breaks an ice block made in a freezer or the like into fine ice pieces.

[Prior Art] Conventionally, shaved ice has been produced by shaving off an ice block put into a case from an end using an ice shaving machine provided with a cutter having a sharp edge at the bottom of the case. In this way, when the ice shaving machine is used, it is inevitable that the cutter, which is a component, becomes expensive and that it takes a considerable amount of time to finish because the ice blocks are gradually scraped off.

Therefore, instead of using a cutter, a convex part (crushing convex part) for crushing the ice block is formed, and the crushing convex part is rotated to collide with the outer peripheral surface of the ice block to accumulate the ice pieces in the accumulation part. However, an ice crusher that can make ice cubes in a short time has been proposed.

[Problems to be Solved by the Invention] However, in the conventional ice crusher, since the crushing protrusions are arranged along the rotation direction of the ice crusher, only the portion of the ice block located at the passage point of the crushing protrusions is present. There is a problem that the crushing efficiency is low because of only crushing.

The present invention has been made in view of the above problems, and an object thereof is to improve the crushing efficiency, and to quickly discharge ice pieces to the accumulating section to crush the ice blocks in a short time. To provide an ice crusher that can.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a container having an opening at the upper end and a storage portion at the lower part, and a container penetrating the bottom surface of the container and projecting into the container to rotate by a motor. An ice crusher including a rotating shaft, a charging cylinder disposed in the container, the upper and lower ends of which are open, and a crusher attached to an upper portion of the rotating shaft and facing a lower end of the charging cylinder. The upper surface of the crushing body is provided with a crushing blade extending in a radial direction of the upper surface, and when the crushing body is rotated, a rotation trajectory surface formed by an upper edge portion of the crushing blade and the It is characterized in that an annular gap facing the accumulating portion is formed between the lower end of the charging cylinder and the lower end.

[Operation] With the above configuration, the crushing blade extending in the radial direction crushes the ice lumps, so that the crushing efficiency of the ice lumps is improved. Furthermore, an annular gap facing the accumulation portion is formed between the rotation trajectory surface formed by the upper edge of the crushing blade and the lower end of the charging cylinder, and the crushing blade extending in the radial direction is rotated by centrifugal force due to rotation. Since it serves as a blade for discharging the crushed ice pieces, the crushed ice pieces can be discharged efficiently and promptly from the annular gap to the accumulating portion, and the ice gap is discharged to the accumulating portion. Since the size of the ice is regulated, it is possible to accumulate ice pieces of only a desired size.

Embodiment An embodiment of the ice crusher according to the present invention will be described below with reference to the drawings.

As shown in FIG. 1, the ice crusher 10 is formed in a substantially cylindrical shape, and has a main body 11 having a motor (not shown) built therein and an ice block to crush ice pieces to accumulate the ice pieces. And a container 12.

On the upper surface of the main body 11, a plurality of container mounting protrusions 11a located concentrically are formed, and serve as a container mounting surface on which a container 14 described later is placed. At the center of the upper surface of the main body 11,
The drive shaft 13 is provided so as to project upward. Drive shaft 13
Rotates in conjunction with a motor, and a drive coupling 14 is fixed to the upper end portion thereof.

In FIG. 1 to FIG. 3, reference numeral 12 denotes a vertically long cylindrical container having a bottom and an accumulating portion S at the bottom, and is integrally formed with a cylindrical container base 15 provided below the bottom. Has been formed. The container 12 is attached to the upper surface of the main body 11 in an upright state, so that the inner peripheral surface of the container base 15 overlaps the container mounting convex portion 11a from the outside, and is detachably attached over the entire area of the container mounting convex portion 11a. It is fitted (see Fig. 1). At the center of the bottom surface of the container 12, a rotary shaft 16 which penetrates the container 12 in the vertical direction and projects into the container 12 is rotatably supported by a bearing 17. At the lower end of the rotary shaft 16, a driven coupling 18
Are fixed, and a connecting member 24 described later is fixed to the upper end portion.

The driven coupling 18 is engaged with the drive coupling 14 at the same time when the container 12 is set on the upper surface of the main body 11, and is disengaged from the drive coupling 14 at the same time as removing the container 12 from the upper surface of the main body 11. Is. Therefore, when the driven coupling 18 and the drive coupling 14 are engaged with each other, the rotation of the motor is caused by the rotation of the drive shaft 13, the drive coupling 14, the driven coupling 18, the rotary shaft 16, and the connecting member 24.
Is transmitted to.

In addition, in the upper part of the container 12, a charging cylinder into which ice blocks are charged.
19 are detachably arranged.

The upper and lower ends of the charging cylinder 19 are opened, and the charging cylinder 19 is formed to be shorter than the container 12. A flange 20 is provided around the entire circumference of the upper end opening of the charging cylinder 19. By placing the flange 20 on the upper surface of the opening of the container 12, the charging cylinder 19 is arranged in the upper part of the container 12 (see FIG. 1). A transparent lid 21 is attached to the upper end opening of the charging cylinder 19.

The lid 21 has a pair of hooks integrally formed on the periphery thereof.
The container 22 is attached by being hooked on the lower surfaces of a pair of hooking protrusions 23 formed integrally with the peripheral edge of the opening of the container 12. By attaching the lid 21 to the container 12, the lid 21 and the container 12
Since the entire flange 20 is sandwiched between the opening 20 and the peripheral edge of the opening, it is possible to suppress the shaking of the throw-in cylinder 19 when the ice blocks are crushed.

The connecting member 24 is tapered toward the upper end, and a rib (not shown) having a tapered locking projection formed on the upper and lower surfaces on opposite sides is formed on the peripheral surface. A pair is provided. The crushing body 25 arranged in the storage section S in the container 12 is detachably attached to the upper portion of the connecting member 24.

The crushing body 25 has a fitting tubular portion 26 that is detachably fitted to the connecting member 24 and a disc portion 27 integrally formed at the upper end of the fitting tubular portion 26. The upper surface 27 of the disk portion 27 facing the lower end of the charging cylinder 19
On a (the upper surface of the crushing body 25), two crushing protrusions (crushing blades) 28, which reach the vicinity of the center from the edge of the disk portion 27 and extend in the substantially radial direction toward the center, are provided upward. It is projected.
The crushing convex portion 28 has a length that is approximately half the radius of the disk portion 27 or more. Both crushing protrusions 28, 28 are formed by bending side portions that are symmetrically located with the center of the strip 29 attached flush with the upper surface of the disk portion 27, in a substantially radial direction. (See Figure 2). The step a between the upper end surface (upper edge) 28a of the crushing convex portion 28 and the disc portion 27 is about 2 mm. The crushed body 25 has a size such that the peripheral edge portion and the lower end of the charging cylinder 19 overlap each other,
At the same time, the outer edge portion (end surface on the outer peripheral side) of the crushing convex portion 28 and the lower end of the charging cylinder 19 also overlap.

Further, the fitting cylinder portion 26 is formed with a pair of slit grooves into which ribs are inserted and an annular groove 30 that crosses both grooves.
A ring spring 31 is attached to the annular groove 30. Therefore, the rib and the slit groove are aligned and the fitting cylinder part
26 is fitted to the connecting member 24, and the ring spring 31 is pushed over by the lower slope of the locking projection, so that the ring spring 31 gets over the tip of the locking projection, and immediately after that the ring spring 31 restores. Then, the crushing body 25 can be easily attached to the connecting member 24 by engaging with the base of the lower slope of the locking projection. Further, by pulling up the crushed body 25 from this attached state, the crushed body is crushed from the connecting member 24 with the operation of the ring spring 31 similar to the case described above.
25 can be easily removed.

In this way, the upper surface of the disc portion 27 of the crushed body 25 is arranged so as to face the lower end opening portion thereof so as to form the bottom of the charging cylinder 19, and at the same time, between the lower end opening portion and the disc portion 27, A gap d is formed which faces the accumulation portion S and serves as an outlet for the crushed ice pieces.
This gap d has a gap of about 3 mm.

The container 12, the driving coupling 14, the driven coupling 18, the charging cylinder 19, the lid 21, the connecting member 24, and the crushing body 25 are each made of synthetic resin, and the driving shaft 13 and the rotating shaft.
The strip 16 and the strip 29 are each made of metal.

Next, an example of the action of the ice crusher having the above configuration will be described.

First, as shown in FIG. 1, remove the lid 21 from the container 12,
For example, about 7 to 8 pieces of ice blocks made in an ice tray in a freezer are charged into the charging tube 19 from the upper end opening. After closing the lid 21, the motor is operated to rotate the rotary shaft 16. As the rotating shaft 16 rotates, the crushing body 25 rotates via the connecting member 24, and the crushing convex portion 28 collides with the ice block. Then, due to the impact at the time of collision, the ice blocks are crushed one after another, and the ice blocks become small ice pieces. On the other hand, the rotation of the crushing body 25 causes the upper surface 28 of the crushing convex portion 28 to
An annular gap d is formed between the rotation trajectory surface formed by a and the lower end of the charging cylinder 19. Then, the crushed ice pieces are discharged to the bottom of the container 12 through the annular gap d,
It is stored in the storage unit S as shaved ice. The crushing of this ice block
It will be completed in about 20 seconds.

At this time, since the outer edge of the crushing convex portion 28 overlaps the lower end of the throwing-in cylinder 19, the size of the ice pieces to be discharged is determined only by the annular gap d, and the ice pieces are discharged from the gap d. The size of the ice pieces is constant. By widening the gap d as the discharge port, for example, crushed ice can be produced, and in this case, the same effect can be obtained.

With such a crushing structure, the ice lumps are crushed by the crushing protrusions 28 extending in the radial direction, so that the crushing efficiency of the ice lumps is improved. Further, an annular gap d facing the storage portion S is formed between the rotation locus surface formed by the upper surface 28a of the crushing protrusion 28 and the lower end of the charging cylinder 19, and the crushing protrusion 28 extending in the radial direction is formed. Serves as a blade for discharging the crushed ice pieces by the centrifugal force due to the rotation, so that the crushed ice pieces can be discharged efficiently and promptly from the annular gap d to the accumulating portion S. In comparison, a desired amount of ice pieces can be produced in a short time. Also,
Since the annular gap d regulates the size of the ice pieces discharged to the storage portion S, it is possible to store only the ice pieces of a desired size. Further, it is only necessary to throw the ice blocks together into the charging tube 19 at a time, and there is no trouble of continuously supplying the ice blocks little by little while the motor is operating. Further, since the crushing convex portion 28 extending in the radial direction serves as a blade for discharging the crushed ice pieces, the discharge of the ice pieces is promoted in addition to the centrifugal force of the disc portion 27, so There is no problem that ice pieces get entangled in the ice blocks and melt out, and the ice blocks stick to each other and spin idle.

The above embodiment shows an electric ice crusher having a container and a main body containing a motor, but by providing a common connecting portion, the container is separated from the main body,
Cooking machine body with a built-in motor instead of a container body
For example, it can be used by being attached to the mixer body.

[Effect] As described above, in the ice crusher according to the present invention, the crushing blade extending in the radial direction crushes the ice lump, so that the crushing efficiency of the ice lump is improved. further,
An annular gap facing the accumulator is formed between the rotation trajectory surface formed by the upper edge of the crushing blade and the lower end of the charging cylinder, and the crushing blade extending in the radial direction was crushed by centrifugal force due to rotation. Since it serves as a blade for discharging ice pieces, the crushed ice pieces can be discharged efficiently and promptly from the annular gap to the accumulating portion, and the annular gap can also increase the size of the ice pieces discharged to the accumulating portion. Because it regulates
Only the desired size of ice pieces can be accumulated. As a result, a desired amount of ice pieces of a desired size can be produced in a short time. Further, since the crushing blade extending in the radial direction functions as a blade for discharging the ice pieces, the ice pieces can be efficiently discharged without providing a member for discharging the ice pieces.
