Description

TECHNICAL FIELD The present invention relates to a grater for grating root vegetables and the like.

In general, root vegetables such as radish are grated and used as condiments for cooking.
A flat plate-shaped grater with a large number of protrusions is used to grate the root vegetables. It is done by letting

By the way, when grating root vegetables and the like using the grater, the root vegetables and the like are grated in an open space while both the root vegetables and the grater are held by hand.
Therefore, the grater, root vegetables, and the like come into contact with the hands, which is unfavorable from a sanitary point of view, and when grated, the grater, vegetable waste, or water scatters and contaminates the surroundings.

On the other hand, for example, Patent Document 1 proposes a conventional technique capable of solving such a problem.

In this prior art, it is possible to insert root crops and pulp fruits into the apparatus, and the rotating operation of the handle is performed under the condition that the apparatus has a mechanical structure that facilitates hygienic retention of the food. This grater is used for root vegetables, pulp and fruits, etc., making it possible to grate the food and store the remaining ingredients in the device in a sealed state by performing the above.

Japanese Patent Application Laid-Open No. 2007-330715

According to the above-described conventional technique, the grated blade and the root vegetables are held in a state covered by the device, and the root vegetables are grated by sliding while pressing the grated blade against the grated blade. The grater operation can be performed without touching the grater, and the grater, its scraps or water can be prevented from scattering to the outside.

However, even the above-described conventional technique still has the following points to be improved.

In the above-described conventional technique, when grating root vegetables, it is necessary to perform two operations at the same time: pressing the root vegetables against the grater blade and sliding the root vegetables in the direction of rubbing against the grater blade.

In addition, it is particularly necessary to maintain a constant force with which the root vegetables or the like are pressed against the grater blade in order to uniformly grate the vegetables.

However, even if the same kind of root vegetables, etc., are different in the degree of reduction when grated due to differences in hardness and structure, etc., the above-mentioned force of pressing the root vegetables, etc. against the grate blade is kept constant. The point is that it is difficult to

DISCLOSURE OF THE INVENTION The present invention has been made to solve the problems remaining in such conventional techniques. The problem to be solved is to provide a grater that enables grating.

A grater of the present invention is a grater for grating root vegetables, etc., in order to solve the above-described problems. A lid detachably attached to close an upper opening, a grater mechanism arranged in the grater main body for grating the root vegetables inserted into the grater, and attached to the lid. and drive means connected to the grate mechanism and operating the grate mechanism.

In the grater of the present invention, root vegetables and the like are placed in the grater main body in which the grater mechanism is arranged, and then the lid is attached to the grater main body so as to cover the opening of the grater main body. By doing so, the drive means attached to the lid is connected to the grate mechanism.

The grater mechanism is then activated by operating the drive means.
When the grate mechanism is actuated in this manner, the grate mechanism grate the root vegetables and the like inserted into the grate main body.

This grating operation is performed in the closed space of the grater body closed by the lid.

Therefore, it is possible to grate the root vegetables without touching them, thereby ensuring hygiene and preventing the grated root vegetables from scattering around.

In addition, since the operation of the grating mechanism by the drive means can be adjusted, the grating operation can be easily made uniform, and therefore uniform grating can be achieved.

The grater mechanism is arranged near the bottom of the grater main body, and includes a substantially disk-shaped grater blade on which the root vegetables and the like are placed on the upper surface, and the grater blade at the center of the grater blade vertically. It can be configured by a rotating shaft provided through it.

In such a configuration, first, the grater blade is inserted into the grater body together with the rotating shaft, and the lower end of the rotating shaft is brought into contact with the bottom surface of the grater body.
As a result, the grater blade is positioned near the bottom surface of the grater body.

Next, after placing root vegetables cut to an appropriate size on the grater blade, the lid is attached to cover the upper opening of the grater body, and the rotating shaft is attached to the lid. connected to the drive means provided.

In this state, the rotating shaft is held along the center line of the grater main body, and the grater blade is held substantially parallel to the bottom surface of the grater main body.

When the grate mechanism is operated by the drive means, the grate blade is rotated around the rotation axis. A relative movement occurs between the grater blade and the root vegetables or the like.

Therefore, the root vegetables and the like are pressed against the grater blade due to their weight, and the root vegetables and the like are grated by the relative rotation of the grater blade with respect to the root vegetables.

The contact pressure between the root vegetables and the grater main body is determined by the gravity acting on the root vegetables, and the size of the contact pressure is kept constant.
This enables uniform grating.

The grater mechanism includes a grater blade projecting from the inner surface of the grater main body, a rotary shaft arranged in the grater main body so as to be rotatable about the center line of the grater main body, and It can be constituted by a rotating shaft and a pressing plate projecting toward the inner surface of the grater main body.

With such a configuration, root vegetables and the like inserted into the grater body are positioned between the pressing plate and the inner wall of the grater body.

When grating, the lid is attached to the grater main body in which the grate mechanism and the root vegetables are inserted so as to cover the upper opening, and the driving means attached to the lid is turned on. It is connected to the rotating shaft of the grate mechanism.

When the rotating shaft of the grater mechanism is rotated by the driving means, the root vegetables and the like are rotated around the rotating shaft by a pressing plate projecting toward the inner surface of the grater main body. be rotated.

In addition, the root vegetables and the like are given a centrifugal force by the pressing plate, and the root vegetables and the like are pressed against the inner surface of the grater main body by the centrifugal force.

Therefore, the root vegetables and the like are moved along the inner surface of the grater body while being pressed against it, and are grated by the grater blade protruding from the inner surface of the grater body in the process of movement. be

Even with such a configuration, the root vegetables are grated in a closed space in the grate to ensure sanitary conditions, and to prevent grating and water splashing to the surroundings to prevent contamination. By generating the contact pressure between root vegetables and the like and the grating blade by centrifugal force, the contact pressure is kept as constant as possible to enable uniform grating.

The driving means is attached to the lid body, and in a state in which the lid body is attached to the grater main body, the driving means is fitted to the upper end portion of the rotating shaft in a state in which relative rotation around the shaft is restricted. A shaft, a wire wheel attached to the drive shaft, a drive wire wound around the wire wheel, and a drive wire interposed between the drive shaft and the lid to connect the drive shaft to the drive wire. and a return spring that biases the winding in the winding direction.

Here, the drive wire is held in a wound state on the wire wheel.

As a result, the grater is fixed by holding down the lid, and the drive wire is pulled out from the lid.

By this operation, the wire wheel, the drive shaft, the rotating shaft, and the grating blade are rotated in the same direction while deforming the return spring so as to tighten it against its elastic force.

When the pull-out force applied to the drive wire is released, the tightening force applied to the return spring is released, and the elastic force of the return spring causes the drive shaft and the wire wheel to rotate in opposite directions. Let me.

Further, by rotating the wire wheel in the opposite direction, the drive wire that has been pulled out as described above is rewound onto the wire wheel.

Therefore, by repeating the pull-out operation and the unwind operation of the drive wire, the above-described grate of the root vegetables can be continuously performed.

Here, when the withdrawal speed of the drive wire is increased, the relative speed of the grater blade with respect to the root vegetables, etc. increases, and the contact pressure between the root vegetables, etc. and the grater blade increases in the initial stage of the grating operation. is determined by the weight of the root vegetables, etc., and is almost constant.

Alternatively, by adjusting the rotation speed of the pressing plate to adjust the centrifugal force generated on the root vegetables, etc., the contact pressure between the root vegetables, etc. and the grater blade can be made substantially constant.

Therefore, by adjusting the drawing speed of the driving wire, the grated state can be easily made uniform.

Moreover, such a grate operation can be performed in a state in which the root vegetables and the like are confined in the space surrounded by the grate main body and the lid.

Therefore, when grating, the user does not touch the grate blade, the root vegetables, etc., and a good sanitary condition can be ensured. Therefore, it is possible to prevent the area around the grater from being soiled.

One end of the drive wire may pass through the side wall of the lid and be pulled out to the outside, and the one end may be equipped with a traction hook for pulling out the drive wire.

With such a configuration, when pulling out the driving wire, the pulling hook can be hooked with a finger.
This makes it easier to pull out the drive wire.

Further, when the wire wheel is rotated by pulling the drive wire in the drawing direction, the drive shaft transmits the rotation of the wire wheel to the rotating shaft, and the wire wheel pulls the drive wire. It is also possible to interpose a one-way clutch that allows relative rotation between the drive shaft and the rotary shaft when rotated in the take-up direction.

With such a configuration, when the drive wire is pulled out, the rotation operation of the drive shaft by the drive wire is stopped. The grater blade continues to rotate due to its inertial force.

Therefore, by appropriately adjusting the withdrawal speed of the drive wire, the grater blade can be rotated more than the amount of rotation that can be directly applied to the drive shaft by the drive wire.

As a result, it is possible to increase the duration of the grate action by the grate blade and realize an effective grate operation.

According to the grater of the present invention, the root vegetables can be grated without touching the root vegetables, etc. by grating them in a state confined inside the grater. Uniform grating can be performed by suppressing changes in contact pressure with the blade.

As a result, it is possible to sanitarily grate the grater and to prevent the area around the grater from being soiled.

However, when the wire wheel 7 is rotated in the direction to wind the drive wire 8, only the inner shaft 6a is rotated to prevent this rotation from being transmitted to the outer shaft 6b. has been made.

On the other hand, a lower plate 13 is attached to the lower portion of the lid 3 so as to close the lower opening of the lid 3 .

At the center of the upper surface of the lower plate 13, there is formed a housing recess 14 into which the outer shaft 6b of the drive shaft 6 is rotatably fitted.

A through hole 4a is formed in the center bottom of the storage recess 14, into which the upper end of the rotating shaft 5 is rotatably inserted.

Thus, the grater 1 of the present embodiment is assembled.

Next, the operation of grating root vegetables such as radishes using the grater 1 of the present embodiment configured as described above will be described.

First, as shown in FIG. 2, after placing a root vegetable V cut to an appropriate size on the grater blade 4 inserted in the grater body 2, the upper opening 2a of the grater body 2 is placed. , and the cover 3 assembled as described above is attached, and the upper end of the rotating shaft 5 is fitted to the lower end of the drive shaft 6 constituting the driving means S attached to the cover 3. Let

In this state, the rotating shaft 5 is held along the center line of the grater main body, and the grater blade 4 is held substantially parallel to the bottom surface of the grater main body 2 .

Here, the drive wire 8 is wound around the wire wheel 7 and held.

From this, the grater 1 is fixed by holding down the lid 3, and the drive wire 8 is pulled out from the lid 3 using the traction hook 11 as indicated by the solid line arrow in FIG. tow to.

By this operation, the wire wheel 7, the driving shaft 6, the rotating shaft 5, and the grater blade 4 twist the return spring 9 against its elastic force, and the broken line in FIG. As indicated by the arrows, they are rotated in the same direction.

The rotational force applied to the grater blade 4 by the drive wire 8 is not directly transmitted to the root vegetables V and the like placed on the grater blade 4 .

Therefore, the root vegetables V and the like are pressed against the grater blade 4 by their weight, and try to maintain a stopped state by inertia when the grater blade 4 rotates.

As a result, the grater blade 4 is relatively rotated with respect to the root vegetables V and the like, so that the above-mentioned Root vegetables V and the like are grated to obtain grated W (see FIG. 4).

When the pull-out force applied to the drive wire 8 is released, the twisting force applied to the return spring 9 is released. is rotated in the opposite direction.

Therefore, during the grating operation, the user does not touch the grate blade 4, the root vegetables V, etc., and a good sanitary condition can be ensured. It is possible to prevent the grater from being soiled by preventing water from scattering.

On the other hand, in the present embodiment, when the drive wire 8 is pulled out, the rotation of the inner shaft 6a of the drive shaft 6 stops together with the rotation of the wire wheel 7. However, due to the action of the one-way clutch 12, The outer shaft 6b of the drive shaft 6 and the grater blade 4 fitted to the outer shaft 6b continue to rotate due to their inertia force.

Therefore, by appropriately adjusting the withdrawal speed of the drive wire 8, the grater blade 4 can be rotated more than the amount of rotation that can be directly provided by the drive wire 8. FIG.

As a result, it is possible to increase the duration of the grate action by the grate blade 4 and realize an effective grate operation.

They are provided at four locations at approximately 90° intervals in the circumferential direction of the grater main body 2 .

A pair of the pressing plates 17 are provided so as to be symmetrical about the rotating shaft 16 .

The edge of each pressing plate 17 on the side protruding from the rotary shaft 16 is formed to have a similar shape to the inner surface shape of the grater main body 2, and the distance between each edge is , smaller than the diameter of the imaginary circle connecting the inner edges of the grater blade 15 .

In this embodiment, as shown in FIG. 6, after the rotating shaft 16 having the pressing plate 17 is arranged in the central portion of the grater main body 2, each of the pressing plates 17 and the grater main body 2 are separated from each other. Root vegetables V are thrown into the space formed by the inner surface, and then the lid 3 is attached to the grater main body 2 so as to cover the upper part thereof. The means S is connected to the rotary shaft 16 so that the lowering operation is possible.

Thus, the lowering operation can be performed by pulling out and returning the towing hook 11 of the driving means S in the same manner as in the above-described embodiment.

By this operation, the rotary shaft 16 is rotated and the pressing plates 17 are moved in the circumferential direction of the grater main body 2. At this time, the inner surface of the grater main body 2 is applied to the root vegetables V and the like. While applying a centrifugal force toward the grater, the grater main body 2 is moved in the circumferential direction as indicated by the arrow in FIG.

Due to such movement of the root vegetables V, the root vegetables V are grated by the grate blade 15 .

Also in this embodiment, the grated W of the root vegetables V is performed in a closed space in the grated device 1 to ensure a sanitary condition, and the grated W and water are prevented from scattering to the surroundings to prevent contamination. Furthermore, by generating contact pressure between the root vegetables V and the like and the grating blade 15 by centrifugal force, the contact pressure is kept as constant as possible to enable uniform grating W.

It should be noted that the shapes, dimensions, etc., of the constituent members shown in the above embodiment are merely examples, and can be changed in various ways based on design requirements and the like.
