Abstract

PURPOSE:To simplify the constitution of the title ice crusher, and to control the shake of the same caused by the crushing of ice blocks by providing a crushing body having a crushing projection disposed on the upper surface of the crushing body, which is opposed to the lower end opening of an ice block shooting cylinder, and by forming the ice block shooting cylinder so as to have its diameter made gradually larger from the lower end opening of said cylinder toward the upper end opening thereof. CONSTITUTION:A crushing body 24 made of a synthetic resin such as polyacetal has a disc part 24b provided unitarily therewith on the upper end of an engaging cylindrical part 24a which engages detachably with a connecting member 23 and, on the upper surface of the disc part 24b, at least one crushing projection 25 is protuberantly provided unitarily with the disc part 24b. The upper end opening of an ice block shooting cylinder 21 is covered with a cover 22 made of a transparent synthetic resin. Since the ice block shooting cylinder 21 is so made that its diameter gradually increase from the lower end opening of said cylinder 21 toward the upper end opening thereof, the uppermost ice blocks among a group of the ice blocks are easily turned sideways when a large quantity of the ice blocks fed into the ice block shooting cylinder 21 receives an upward force by the crushing action. Accordingly, the rate of crushing energy transmitted to the lower part of the ice block shooting cylinder 21 via the ice blocks to be crushed can be minimized.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] 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.

[Conventional technology]

Figures 10 and 11 show a conventionally provided electric ice crusher, and 1 in Figure 10 is a main body case with a built-in motor (not shown) that is operated by receiving power from dry batteries. The crushing fittings 2 are installed in an inverted V-shape arrangement. A crushing body 3 which is rotated by the power of the motor is provided between these crushing metal fittings 2, and a container 4 with an open top is provided below these crushing metal fittings 2 and the crushing body 3 as shown in FIG. It is removably attached along the direction of the solid line arrow.

The crushing body 3 is arranged with its axis horizontal, and this
As shown in Fig. 1, there is a main body 7 made of synthetic resin in which a plurality of flanges 6 are integrally protruded around a fitting shaft portion 5 to which the rotating shaft of the motor is attached, and a body 7 made of synthetic resin that extends through the flanges 6. It is formed from two pivot shafts 8 provided parallel to the fitting shaft portion 5 and a crushing rod 9 rotatably attached to these pivot shafts 8. Each crushing rod 9 passes through the recess 2a of the crushing fitting 2 as the crushing body 3 rotates.

When this ice crusher is used, about 1 to 3 ice cubes A are thrown into a space with the crushing metal fitting 2 and the crushing body 3 at the bottom while the motor is operating while checking the crushing situation. By doing so, the crushing rod 9 can be forcefully collided with the ice block A riding on the crushing fitting 2 and the crushing body 3 due to the centrifugal force, and by repeating this, the ice block A is turned into small pieces of ice and is inserted into the recess 2a of the crushing fitting 2. Let it pass,
It can be received in the lower container 4.

[Problem to be solved by the invention]

However, in the conventional type, since the crushing rod 9 is rotatably supported, it escapes in the counter-rotational direction when crushing the ice block A, resulting in poor crushing efficiency and a long time for crushing. The problem is that you need it.

In addition, in the above-mentioned conventional configuration, when the crushing rod 9 is fixed and the driving force of the motor is increased, there is no guarantee that the ice block A will be successfully broken by a single impact, so it is possible that uncrushed ice blocks may be bitten. This is impractical because there is a high possibility that the rotation of the crushing body 3 will be hindered and the motor will be burnt out.

Further, in the conventional structure, the structure of the crushing body 3 is complicated as shown in FIG. 11, and there is also a problem that the cost is high.

SUMMARY OF THE INVENTION An object of the present invention is to obtain an ice crusher that can improve crushing efficiency, has a simple configuration, and can suppress vibration caused by crushing ice blocks.

Another object of the present invention is to obtain an ice crusher that prevents ice pieces from becoming too small while maintaining the effect of suppressing agitation accompanying crushing of ice blocks. Another objective is to obtain an ice crusher that reduces vibration during crushing.

[Means to solve the problem]

In order to achieve the above object, the ice crusher of the present invention includes a container with an open top surface, a rotating shaft that vertically penetrates the bottom wall of the container and is rotated by the power of a motor. An ice piece outlet gap is provided between an ice cube charging cylinder which is open at both upper and lower ends and arranged at the upper part of the container, a lid provided to cover the upper end opening of the ice cube charging cylinder, and a lower end of the ice cube charging cylinder. A crushing body is formed and attached to the upper part of the rotating shaft, and has a crushing body having one crushing convex portion on the upper surface facing the lower end opening of the ice cube loading tube, and the ice cube loading tube is attached to the top of the rotating shaft. It has a shape that gradually becomes larger in diameter from the lower end opening toward the upper end opening.

In addition, in order to maintain the effect of suppressing the agitation that accompanies the crushing of ice cubes and to prevent the ice pieces produced from becoming too small, the ice cube feeding tube is provided with a straight pipe section at the bottom of which the diameter does not change. It is preferable to have a configuration including a tapered pipe part that is connected to the upper end of the straight pipe part and gradually becomes larger in diameter toward the upper end opening.

Furthermore, in order to reduce the vibration during crushing,
The ice cube charging tube is detachably attached to the container, and a support is provided on at least the lower outer surface of the ice cube loading tube, protruding toward the inner circumferential surface of the container and having a tip thereof close to the inner circumferential surface of the container. It is preferable to have a configuration with ribs.

[Effect]

When ice cubes are put into the ice cube input cylinder of the ice crusher configured as described above, and the top opening of the cylinder is covered with a lid and the motor is operated, the crushing body rotates together with the rotating shaft, resulting in crushing of the top surface. The convex portion collides with the ice blocks located at the lower end of the ice block input cylinder, and breaks these ice blocks into small pieces of ice.

By the way, since the diameter of the ice cube charging cylinder gradually increases from the bottom opening to the top opening, when a large group of ice blocks thrown into the tube receives an upward force, some of the ice blocks The ice block at the top can easily move laterally.In addition, the ice block loading cylinder supports part of the large amount of ice blocks thrown into it, and the ice block at the bottom is crushed by the crushing body. Can reduce weight.

Therefore, as a result, the degree of freedom of the ice blocks when subjected to an upward force can be increased, making it easier for the crushed ice blocks to escape upward when the ice blocks are crushed by the crushing convex portion, and the crushing energy is It is possible to reduce the rate at which ice cubes are transmitted to the lower part of the ice cube dumping tube via the ice cubes. Therefore, the impact exerted on the ice cube charging cylinder due to crushing is reduced, and the shaking of the container supporting the ice cube charging cylinder can be suppressed to a small level.

The ice pieces made as described above are discharged along the top surface of the crushed body by centrifugal force through the ice piece outlet gap between the crushed body and the lower end of the ice cube input cylinder, and are discharged to the bottom of the container. It can be accumulated.

Moreover, the crushing body of the ice crusher of the present invention has a crushing convex portion protruding from the upper surface opposite to the lower end opening of the ice block charging tube,
In addition, since the structure is attached to a rotating shaft, it is possible to eliminate the need for many flanges, pivots, etc. as in the conventional case, and therefore the structure is simple with fewer components and can be obtained at low cost.

In addition, the straight pipe formed at the bottom of the ice cube input tube stores the lowest ice cube inside, and limits the freedom of movement of the ice cube in the lateral direction as described above. do. However, since the tapered pipe section connected to the upper end of this straight pipe section guarantees the freedom of the ice blocks as described above, the movement of the ice blocks as a whole is suppressed and the ease with which they escape upward is increased. To compensate for the damage, the time required to crush the ice cubes can be shortened.

Furthermore, the tip of the support rib provided on the outer surface of the lower part of the ice cube charging tube comes close to the inner circumferential surface of the container when the charging tube is stored in the upper part of the container. However, the impact associated with the crushing of ice cubes occurs at the lower part of the ice cube charging tube, and when the lower part attempts to sway, the support ribs immediately come into contact with the inner circumferential surface of the container. It supports the ice cube charging cylinder and prevents it from shaking.

〔Example〕

A first embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

In Fig. 1, reference numeral 11 denotes a cooking device main body, for example, a mixer main body, which has a built-in motor (not shown), and a convex portion 12 is formed on the upper surface of the main body 11, on which a plurality of containers located on a concentric circle are mounted. ing.

A metal drive shaft 13 projects upward from the center of the upper surface of the main body 11 . The drive shaft 13 is rotated in conjunction with the motor, and has a drive coupling 15 made of synthetic resin fixed to its upper end. Note that the above configuration is a conventionally well-known configuration for mixers.

In FIGS. 1 to 3, reference numeral 16 denotes a vertically elongated container having a cylindrical shape with a bottom, which integrally has a cylindrical container stand 17 provided below the bottom wall 16a.

Then, as shown in FIG. 1, the container 16 is placed on the container stand 1.
When installing the container, make sure that the inner peripheral surface of 7 overlaps with the convex part 12,
These protrusions 12 are removably fitted over each other so that they can be mounted upright on the upper surface of the mixer main body 11.

The container 16 is made of transparent or opaque synthetic resin, and a metal rotary shaft 18 vertically passing through the bottom wall 16a is rotatably supported by a bearing 19 at the center of the bottom wall 16a. A driven coupling 20 made of synthetic resin is fixed to the lower end of the rotating shaft 18. This coupling 20
The container 16 is disengaged from the drive ring 15 at the same time as the container 16 is set on the upper surface of the mixer main body 11.

At the upper part of the container 16, an ice cube charging cylinder 21 made of synthetic resin is removably arranged. The charging tube 21 is shorter than the container 16, has both upper and lower ends open, and is formed into a tapered tube shape whose diameter gradually increases from the lower end opening toward the upper end opening. Moreover, a ring-shaped flange portion 21a is integrally provided on the upper opening edge of the ice cube charging tube 21, and this flange portion 21a
is placed on the upper surface of the upper opening of the container 16, as shown in FIG.

In the case of this embodiment, the ice block charging tube 21 is molded from a synthetic resin material with high elasticity such as polyethylene resin, polypropylene resin, or nylon resin. Thereby, polyacecool resin, polycarbonate resin, or A
Compared to the case of molding with a synthetic resin with poor elasticity such as BS resin, it is possible to reduce the risk of the ice cube charging tube 21 being damaged by the impact when the ice cubes are crushed, which will be described later, and the impact can be alleviated by its elastic deformation. This is to reduce impact noise.

The upper opening of the ice cube charging cylinder 21 is made of a transparent synthetic resin lid 22.
covered with. The lid 22 is attached by engaging a pair of hooks 22a integrally provided on the periphery of the lid 22 with the lower surfaces of a pair of first engaging protrusions 16b integrally provided on the outer surface of the opening edge of the container 16, respectively. And this lid 22
By attaching it to the container 16, the entire flange portion 21a is sandwiched between it and the upper opening edge of the container 16, thereby suppressing the movement of the ice cube charging cylinder 21 during ice crushing.

Note that 16c in the figure is a second engaging convex portion provided below the first engaging convex portion 16b. This second engaging convex portion 16c is
It is used to attach the lid 22 to the container 16 when the ice cube charging cylinder 21 is removed and used for whipping, for example. It should be noted that the hooking and unhooking of the hooking portions 22a to the hooking convex portions 16b, 16C is accomplished by rotating the lid 22 in the circumferential direction.

A connecting member 23 made of synthetic resin is fixed to the upper part of the rotating shaft 18. Although the details of this member 23 are not shown, it becomes tapered toward the upper end, and a tapered locking convex portion is formed at the upper end, and the upper and lower surfaces of the member 23 are formed with sloped surfaces facing in opposite directions. It has a pair of ribs. This connecting member 23 has a crushing body 2 disposed in the lower part of the container 16.
4 is removably attached.

The crushed body 24 is made of synthetic resin such as polyacetal,
As shown in FIGS. 1 to 3, a disc part 24b is integrally provided at the upper end of a fitting cylinder part 24a that is removably fitted to the connecting member 23, and at least one fracture is formed on the upper surface of this disc part 24b. It is formed by integrally protruding a convex portion 25. Crushing convex part 2
5 is provided, for example, by bending upward one end of the metal band plate 26 attached flush to the upper surface of the disc part 24b, but is not limited thereto, and is provided by integrally molding it to the disc part 24b. Alternatively, it may be formed into a rod shape or the like.

In addition, a pair of slit grooves (not shown) into which the ribs (not shown) are inserted are formed in the fitting cylinder part 24a, and an annular groove that crosses these grooves is formed, and a ring is inserted into this annular groove. A spring 27 is attached. Therefore, by aligning the ribs and the slit grooves and fitting the fitting cylinder portion 24a into the connecting portion to the member 23, the ring spring 2
7 is pushed out and this spring 27 gets over the tip of the locking convex part, immediately after that, the ring spring 27
The crushed body 24 is easily attached to the connecting member 23 by being restored by its elastic force and being locked to the base of the lower sloped surface of the locking convex portion. Further, in this attachment, by pulling up the crushing body 24 from the state, the crushing body 24 can be easily removed from the connecting member 23 with the operation of the ring spring 27 similar to the case described above.

With the above installation, the disk portion 24 of the crushing body 24
The upper surface b is arranged to form the bottom of the ice block input cylinder 21 and to face the lower end opening thereof, and an ice piece outlet gap G is formed between the lower end opening and the disc part 24b. ing. This gap G is formed to be smaller than the size of a cube-shaped ice block made in the freezer compartment of a refrigerator used in a general household.

The ice crusher having the above structure is used by being attached to the upper surface of the mixer main body 11. In other words, in this set state, the lid 2
2, and put, for example, about 7 to 8 ice cubes made from an ice cube tray in the freezer into the ice cube input tube 21 from the opening at its upper end. Then, after closing the lid 22, the motor is operated by a commercial AC power source to rotate. Rotate the shaft 18.

Then, since the crushing body 24 rotates together with the rotating shaft 18 via the connecting member 23, the crushing convex portion 25 collides with the ice blocks, and the impact causes the ice blocks to be crushed one after another to form small ice pieces. can. Then, the crushed ice pieces are discharged through the ice piece outlet gap G by the centrifugal force of the crushing body 24 and stored at the bottom of the container 16.

Note that the time required to complete crushing of the ice block is about 7 seconds.

Therefore, according to the above-described crushing structure, since the crushing convex portion 25 does not escape when breaking the ice block, the crushing efficiency can be improved, and the desired amount of ice pieces can be produced in a shorter time compared to the conventional method. In addition, the ice blocks need only be thrown into the ice block input cylinder 21 all at once, and there is no need to continuously supply ice blocks little by little while the motor is operating.

When the ice cubes are crushed as described above, a force that shakes the ice cube charging tube 21 acts as the ice cubes are crushed, and at the same time, the container 16 is shaken.The reason for this shaking of the container 16 is as follows. This can be suppressed to a smaller size.

In other words, since the diameter of the ice block charging tube 21 gradually increases from the lower end opening to the upper end opening, when a large number of ice blocks thrown into the tube are subjected to an upward force due to the above-described crushing operation, , the uppermost ice block in this group of ice blocks can easily move laterally. In addition, ice block injection cylinder 2
1 can support a part of a large group of ice blocks thrown into it, and can reduce the weight applied to the lowest ice block crushed by the crushing body 25.

As a result, the degree of freedom of the ice blocks when subjected to an upward force by the above-described crushing operation is increased, and the crushed ice blocks can be easily released upward when the ice blocks are crushed by the crushing convex portion 25. Since the ice block escapes upward, the rate at which crushing energy is transmitted to the lower part of the ice block input tube 21 via the crushed ice block can be reduced. Therefore, the impact applied to the ice block charging tube 21 due to crushing is reduced, and the shaking of the ice cube charging tube 21 and, by extension, the shaking of the container 16 can be suppressed to a small level.

Therefore, when using this ice crusher, the lid 22
Even when the container 16 cannot be pressed by hand, there is no risk that the container mounting of the container 16 to the container stand 17 and the mixer main body 11 will be unintentionally disengaged from the convex portion 12 due to the movement of the container 16.

Incidentally, if the ice block charging tube 21 has a straight tube-like configuration with no change in diameter over its entire length in the vertical direction, the ice block located at the bottom of the large amount of ice blocks stored therein will be When the entire weight of the ice cubes other than is restricted from escaping upward. Therefore, the rate at which crushing energy is transmitted to the lower part of the ice block input tube through the crushed ice blocks is increased.
As the ice cubes are crushed, the impact on the ice cubes is also increased.
It is easy to give a large amount of vibration to this straight tube-shaped input cylinder.

Further, the crushing body 24 has a crushing convex portion 25 protruding from the upper surface of the disk portion 24a facing the lower end opening of the ice block input tube 21, and has a fitting tube portion 24a attached to the rotating shaft 18. Because of this structure, it is possible to eliminate the need for many flanges, pivots, etc. as in the past. Therefore, it has a simple structure with fewer components and can be obtained at low cost.

The second embodiment of the present invention shown in FIG.
It is formed of a straight pipe part 21b whose diameter does not change at its lower part, and a tapered pipe part 21c which is connected to the upper end of this straight pipe part 21b and gradually becomes larger in diameter toward the upper end opening.

Of course, a ring-shaped flange portion 21a is formed at the upper end (that is, the upper opening edge) of this tapered tube portion 21c. The length A of the straight pipe portion 21b is set to 20 to 30 m+i, and the dimension B between the straight pipe portion 21b and the crushed body 24 is approximately 1 oin. This dimension is equal to the maximum length of one side of the square ice block formed in the ice cube tray, thereby minimizing the vertical stacking of ice blocks in the straight pipe section 21b. This prevents the upward escape action from being significantly impaired. The configuration other than the background is the same as that of the first embodiment, including the points not shown, so the explanation thereof will be omitted.

In such a configuration of the second embodiment, the ice block charging cylinder 2
The straight pipe part 21b formed at the lower part of the pipe 21b accommodates the lowermost block of ice therein, and allows the block of ice to have a degree of freedom of movement in the lateral direction as explained in the first embodiment. Restrict. However, in the tapered pipe part 21c that continues to the upper end of the straight pipe part 21b and occupies most of the ice block charging tube 21, the movement of the ice block in the lateral direction is prevented for the same reason as explained in the first embodiment. Since the degree of freedom is guaranteed, the ease with which the ice cubes can escape upward from the ice cube charging tube 21 as a whole is only slightly reduced. Therefore, while suppressing the shaking of the container due to the impact caused by the crushing of the ice cubes, the time required to crush the ice cubes can be shortened to compensate for the loss of ease of upward escape in the straight pipe portion 21b. Therefore, it is possible to prevent the ice from breaking too finely, and to obtain ice pieces of a predetermined size.

In the third embodiment of the present invention shown in FIGS. 5 to 7, a straight pipe portion 21b with no change in diameter is provided at the lower part of the ice cube charging tube 21, as in the second embodiment, and this straight pipe portion 21b In addition to the configuration in which a tapered pipe portion 21c is provided which is connected to the upper end and gradually becomes larger in diameter and shorter as it goes toward the upper end opening, an upper straight pipe having a larger diameter than the straight pipe portion 21b is provided at the upper end of the tapered pipe portion 21c. A portion 21d is provided. Of course, the lower straight pipe section 21
The relationship between the length A of b and the distance B between this and the crushing body 24 is also set to be the same as in the second embodiment.

Therefore, according to the third embodiment, for the same reason as the second embodiment, it is possible to crush the ice block in a short time while suppressing the vibrations caused by the crushing of the ice block. In addition, since the upper straight pipe part 21d is formed, when the amount of ice blocks decreases and the ice blocks are thrown upward by the crushing convex part 25, they are guided by the vertical surface of the upper straight pipe part 21d and quickly downward. It can be crushed by returning it to In other words, the time required to complete crushing can be shortened.

For comparison, if the upper straight pipe part 21d is not present and the tapered pipe part 21c is long, the ice cubes thrown upward will ride on the inner peripheral surface of the tapered pipe part 21c and rotate. Although it takes time for the fall to fall, in the case of this embodiment, although it is the same as falling while turning, there is no situation where the person rides on the upper straight pipe portion 21d, so the time is reduced by that amount. , can be dropped quickly.

By the way, the ice pieces that have become finer due to crushing are easier to melt, so the fact that the crushing time can be shortened as described above means that the crushing can be completed before the ice pieces accumulated at the bottom of the container 16 begin to melt. , it is preferable to take out the ice pieces from the container 16 and use them.

Further, in the third embodiment, a plurality of supporting ribs 28 are integrally provided on the outer surface of the lower part of the ice cube charging cylinder 21 and protrude toward the inner circumferential surface of the container 16.

These ribs 28 are provided so that when the ice block introducing cylinder 21 is placed in the container 16, the tips thereof are close to the inner circumferential surface of the container 16 to suppress the movement of the ice block introducing cylinder 21. In the case of this embodiment, for example, along the axial direction of the ice block charging tube 21, they are continuously formed from the lower end to the upper end of this tube 21, and are provided at three or more locations. However, the supporting ribs 28 may be provided continuously or discontinuously along the circumferential direction on the outer surface of the ice block charging cylinder 21, and may be provided at least on the lower outer surface of the ice block charging cylinder 21. In addition, for the same purpose, the ice block charging cylinder 2
A plurality of short ribs (not shown) are also formed on the upper outer surface of 1.

By having such a support rib 28, when the lower part of the ice cube charging cylinder 21 tries to sway due to the impact generated at the lower part of the ice cube charging cylinder 21 as the ice cubes are crushed, the support rib 28 immediately comes into contact with the inner circumferential surface of the container 16. By supporting the ice cube charging cylinder 21 on the container 16 via the supporting ribs 28, it is possible to prevent the ice cube charging cylinder 21 from shaking.

Therefore, the amount of oscillation of the container 16 can be reduced.

Further, when the support ribs 28 are provided in the vertical direction as in this embodiment, stability can be improved when the ice block charging tube 21 is placed alone.

It should be noted that the configuration other than the above points is the same as that of the second embodiment, including the points not shown in the drawings, so a description thereof will be omitted.

A fourth embodiment of the present invention shown in FIGS. 8 and 9 has upper and lower straight pipe portions 21b and 21d in the configuration of the third embodiment.
A vertical rib 29 extending along the axial direction of the ice block charging cylinder 21 is integrally provided on the inner surface thereof. Since the configuration other than this point is the same as that of the third embodiment, including the points not shown, the explanation thereof will be omitted.

The rotation of the crushing body 24 imparts rotational motion along the inner circumferential surface of the ice block charging cylinder 21 to the group of ice blocks thrown into the ice block charging cylinder 21 . If the distribution of ice blocks is not uniform due to such rotational movement, the imbalance causes the ice block charging tube 21 to wobble, causing the container 16 to oscillate. However, according to the configuration in which the vertical ribs 29 are provided as in this embodiment, the rotational movement of the ice block group along the inner circumferential surface of the ice block charging tube 21 can be hindered, so that the movement of the container 16 can be reduced. Useful. However, since the ice blocks are disturbed when their rotational movement is prevented by the vertical ribs 29, the ice blocks and the crushed bodies are
4. As a result, the time required to complete crushing can be shortened.

Note that although each of the above embodiments is configured as described above, the present invention is not limited to these embodiments.

For example, the crushing body 24 may be fixedly attached to the rotating shaft 18. Further, the lid 22 may be sized to correspond to the upper end opening of the ice block charging cylinder 21, and may be detachably attached directly to this upper end opening. Furthermore, the ice block charging tube 21 may be provided with its flange portion 21a adhered to the container 16.

〔Effect of the invention〕

In addition to improving the efficiency of crushing ice blocks and making ice pieces in a short time,
The structure of the crushed body is simple and can be obtained at low cost. Since the ice cube charging tube is shaped so that its diameter gradually increases from the bottom opening to the top opening, the impact applied to the ice cube loading tube due to crushing is reduced, and the shaking of the container that supports the ice cube loading tube is reduced. Can be kept small.

According to the ice crusher of claim 2, since the straight pipe part with no change in diameter is provided at the lower part of the ice block charging tube, the effect of suppressing the oscillation accompanying the crushing of the ice blocks can be maintained while reducing the amount of time required to complete the crushing of the ice blocks. By making the time shorter, you can prevent the ice pieces made from becoming too small.

According to the ice crusher according to claim 3, since the supporting rib protruding toward the inner circumferential surface of the container is provided on at least the outer surface of the lower part of the ice cube inlet, the movement of the lower part of the ice cube inlet is prevented, and the container is prevented from moving during crushing.
