DETAILED DESCRIPTION OF THE INVENTION

[0001]

SUMMARY OF THE INVENTION The present invention relates to a rice sharpener which can be mechanically operated without immersing the palm in water in rice sharpening work which is a pre-cooking operation. An object of the present invention is to provide a rice sharpener having a novel structure that allows a simple and efficient rice sharpening operation to be performed simply with a light reciprocating movement while being in a floating state.

[0002]

[Prior Art] The "rice separation phenomenon" has been around for a long time, but it is said that it is said that it is said that it will be a bad harvest and domestic rice will be drastically short and that only bad foreign rice will be eaten Then, the staple food in Japan is rice, not bread or noodles. One of the reasons rice rice has been shunned by young people and double-income couples is that unlike rice and bread, noodles require a lot of time and effort to prepare them, and they do not fit in with the busy lifestyles of today. There's a problem. In particular, there is a dislike that the washing operation of rice polishing is judged to be troublesome just because the hands have to be immersed in water, and many people still hate rice for that reason.

[0003] Therefore, in order to encourage and promote the rice food for such people, it is becoming increasingly necessary to grind the rice that has already been subjected to a water-washing treatment without having to grind it. Naturally, those processed rices also have higher unit prices, and thus certainly have become more convenient, but for economic reasons, people who have avoided rice as described above are still It is still in its current state and has not changed its lifestyle at all.

[0004] As this situation clearly shows, the biggest difficulty with cooked rice is that it is all the time and effort associated with the rice sharpening work, and "rice sharpening" must be performed prior to this rice cooking. The work is
Normally, it is the work of washing the rice until the sharpening juice becomes almost transparent.If it is neglected to do this rice sharpening work or to cook rice without performing sufficient rice sharpening, the cooked rice will be cooked The rice bran smell will remain in the rice and it will be hard to say that it is delicious rice, so this rice sharpening work is an important task that is indispensable even for both Become.

[0005] A traditional method of sharpening rice, which is a ground for inconvenience, is to put a predetermined amount of rice into a slightly larger bowl body or a body such as an inner pot of a rice cooker, add an appropriate amount of water, and scrape by hand. After mixing and washing the rice, discard the dirty water, replace it with fresh water and repeat the washing several times, and it will be necessary to replace the water each time until the water is almost transparent, When draining dirty water, you have to use a certain amount of nerves so that the rice in the middle does not flow out together.

Therefore, instead of such a traditional manual operation, after a certain amount of rice and an appropriate amount of water are put into the main body, the rod is reciprocated in the vertical direction in the main body, and the rotating blades are moved. There has been provided a rice sharpener that agitates rice by rotating or the like to bring rice grains into contact with each other and wash away rice bran adhering thereto. However, many of these previously proposed rice sharpeners are large and cumbersome to handle with an electric motor, or when the rice is sharpened, the water in the body becomes cloudy. If this is the case, the water in the main unit must be replaced each time, and rice accumulates on the bottom of the main unit above all, as in the traditional rice sharpening work described above. Most of the instruments have a structure, and even if the operating rod or stirring blade is operated in such a state, the rice is compacted or only partially stirred, and the whole rice is not sufficiently sharpened. It had the drawback of ending.

[0007] In view of the situation of the conventional rice sharpeners, there is no need for a power source at all, and even a woman can easily operate it by hand. We have been engaged in the development and research of low-cost rice sharpeners, and after many years of trial and error, we have finally completed a simple rice sharpener with a new structure that can achieve the intended purpose. In the following, the configuration will be described in detail together with specific examples.

[0008]

As will be understood from the typical embodiments shown in the drawings, the present invention basically has the following structure. That is, it is composed of a cylindrical rice-sharpening main body having a water supply port at an appropriate position on the side surface, and a bottom lid portion that allows the bottom of the rice-sharpening main body to be freely opened and closed. After the reciprocating shaft is disposed, the operating rod with a stirring blade that guides the reciprocating shaft is movable back and forth with respect to the rice sharpening main body, and the stirring blade of the operating rod with the stirring blade is the operating rod of the operating rod. During the forward / backward movement, only when the forward movement is performed, the combination is made such that it is tiltable and foldable in the direction of the arrow with respect to the traveling direction, and at least the bottom lid portion does not allow rice grains to pass therethrough. A rice sharpener whose gist has a large number of regulated drain holes or drain grooves.

The rice-sharpening body is preferably made of a transparent material such as glass or plastic which can see through the inside, and the amount of rice consumed by a general family is about 3 times the total volume of the rice. It is of a size that can be accommodated in two-thirds or less, and is formed in a cylindrical shape in which the ratio of the cross-sectional diameter of the bottom surface to the length of the side surface is, for example, approximately 1: 3. Then, it is convenient, in addition to a cylindrical one, a polygonal cross-section cylindrical body, a truncated cone-shaped cylindrical body, etc., and the main body hollow portion is straight (however, even if there are small projections or uneven portions on the entire inner surface, it will be described later. A rod that does not hinder the forward / backward movement of the operating rod with a stirring blade is included). In addition, the introduction of rice into the rice sharpening body, outside the upper end opening, open the bottom lid described later, or double as a water supply port, in some cases, by forming a dedicated input port at an appropriate place To be implemented.

The bottom cover has a function of closing the bottom of the main body so as to prevent the rice stored therein from falling down, and opening the bottom of the container after sharpening the rice and easily removing the rice. In addition to making it the same material as the rice sharpening body, it is not necessarily limited to transparent materials, wood,
It is also possible to use bamboo material or a metal material such as aluminum or stainless steel that does not easily rust, and it should be formed to have the same or slightly larger cross-sectional shape as the bottom of the rice sharpening body, and a large number of drain holes or drain grooves. It must be constructed such that the bottom of the rice sharpening main body is not opened or detached from the main body while the rice is being ground.

The structure for attaching the bottom cover to the bottom of the rice sharpening body is as follows:
In addition to those shown in the embodiments described below, for example, after the bottom cover is fitted into the inner surface of the container bottom, hook hooks or other appropriate means for preventing escape are taken, or a structure that slides in and out from the lateral direction. In addition to the one that is formed in an attachment structure that allows complete removal from the rice sharpening body, such as a shaft attachment structure that enables rotation around a shaft pin, It is only necessary to adopt an appropriate structure that does not separate from the rice sharpening body.

A large number of drain holes or drain grooves formed in the bottom cover are for discharging the rice sharpening juice in the main body, and the rice grains are prevented from spilling together with the sharpening juice. It must be formed to have a diameter or width smaller than the size of the drainage hole, and an arrangement for drainage suitable for the rice sharpening effect, for example, the diameter of the drain hole is about 3
In the case of millimeters, the holes are formed at an optimum interval such that the small holes are arranged at intervals of about 4 mm. The drain holes or the drain grooves can be formed on the entire side surface of the rice-grinding main body or on an appropriately selected side surface in order to ensure drainage efficiency suitable for the rice-grinding effect.

The water supply port is basically for supplying the water discharged from the faucet into the rice sharpening body, and a suitable place on the side of the body is formed into a circular shape having a diameter that does not hinder the water supply. It has a structure that can easily supply water from the water tap or the hose connected to the tap into the rice sharpening body, such as by making it into an elliptical shape or the like, making the periphery of it funnel-shaped, or connecting the hose port directly. I will do it. In addition,
This water inlet is not limited to one place for the rice sharpening body,
For the purpose of increasing water supply efficiency or complicating the flow of water in the rice-grinding main body, it is also possible to appropriately form a plurality of them.

The operating rod with stirring blades is mounted so as to be able to advance and retreat with a reciprocating axis arranged parallel to the axis of the rice sharpening body as a guide, and floats in the water supplied in the process. It stirs the dancing rice and causes the rice grains to collide with each other or the stirring wings of the operating rod to remove dirt such as rice bran from the surface of the rice grains. It shall be made of a rod-shaped or cylindrical member having a strength that will not be lost, and for example, besides the one shown in the embodiment, supported by an appropriate width so as to guide the operation rod with a stirring blade in the upward direction of the rice sharpening main body A structure having such a structure or a structure configured to support at two or more places at appropriate intervals to induce advance / retreat is adopted.

[0015] The stirring blade is formed at or near the tip of the operating rod, and at least at an appropriate stage in the advancing / retracting device of the operating rod, is formed so as to project at least substantially perpendicularly or slightly inclined to the axis of the operating rod. It has a function of forcing the rice contained in the rice sharpening body to be agitated during the operation of the operating rod, so that at least the rice contained therein is agitated. For example, in addition to a flat plate, a thin bar, a ring, a spiral, a curved shape, etc., which can further increase the stirring efficiency, can be adopted. Along with
As shown in the embodiments described later, the operating rod is combined with the operating rod in such a manner that it can be tilted and foldable in the direction of its advance only in the forward operation during the forward / backward operation of the operating rod. However, a structure that influences the forward / backward operation not only deteriorates the operability but also may damage the stirring blade itself or the attachment structure with the operating rod. There must be.

[0016]

[Related Invention 1] The present invention relates to a rice sharpener having the above-described basic configuration, and a water supply port is provided on a side surface of the rice sharpening body so that rice can be easily put into the rice sharpening body. Separately, a rice sharpener with a specially designed rice inlet is also included. That is, it comprises a cylindrical rice-sharpening body having a water supply port and a rice-inlet in the right side, and a bottom lid that allows the bottom of the rice-sharpening body to be freely opened and closed. The advancing / retracting shaft is arranged in parallel, and the operating rod with a stirring blade that guides the advancing / retracting shaft is movable back and forth with respect to the rice sharpening body, and the agitating blade of the operating rod with the agitating blade is Only when the operating rod is moved forward and backward, the operating rod is combined with the operating rod so that it can be folded and foldable in the direction of its arrow with respect to the traveling direction, and at least the bottom lid portion passes through rice grains. This is a rice sharpener having a configuration in which a large number of drain holes or drain grooves regulated to a size that does not allow the drain hole to be formed are formed.

The rice input port is a dedicated port for inputting the rice to be ground into the main body of the rice sharpener, and there is no fear that the function of the above-mentioned water supply port is disturbed, and the rice is sharpened during the rice polishing. It must be formed in a shape and size that allows a predetermined amount of rice to be put in without spilling on the side of the rice sharpening main body that does not have It should be done so that the rice does not spill out or stay in the same area while grinding the rice, and should be concealed by a cap as appropriate.

[0018]

[Related Invention 2] The present invention further includes a rice sharpener having the following structure, which is characterized in particular by the structure of the advancing / retracting operation rod with stirring blades and the structure of the rice inlet. That is, a large number of drainage holes or drainage grooves regulated to a size that does not allow rice grains to pass through the bottom opening of the cylindrical rice sharpening body are drilled, and the bottom lid is detachably combined with the rice. Inside the sharpening body, the operating rod with a stirring blade is movable back and forth by using a shaft member arranged parallel to the axis thereof as a guide, and the stirring blade of the operating rod with the stirring blade is operated by the operation blade. During the forward / backward movement of the rod, only when the forward movement is performed, it is incorporated into the rod so that it can be folded and folded in the direction of the arrow in the direction of travel. This is a rice sharpener whose main feature is that a water supply port and a rice input port are juxtaposed and a cap with a grip handle is detachably covered at the rice input port.

The operating rod with stirring blades only needs to be formed in such a structure that the operating rod itself can be advanced and retracted by hand from the outside of the rice sharpening main body. To perform the reciprocating operation, the operating rod tip side is not simply inserted into the rice sharpening main body in a free state, but a shaft member portion is arranged in the rice sharpening main body so as to be parallel to the axis. It is desirable that the operating rod be guided along the shaft portion so as to realize the forward / backward operation.

Further, the rice inlet, which is separate from the water inlet and is formed exclusively for charging rice, has a configuration convenient for simply charging rice, that is, considerably larger than the water inlet. Of course, it is also possible to have a structure in which a large mouth is formed and a cap is appropriately covered with a cap, and the rice sharpening body is fixed by hand by directly gripping the same place. However, in order to further stabilize the gripping operation, the rice inlet itself is integrally formed in a funnel-shaped protruding shape from the rice sharpening main body, and it is attached to the surface of the cap covered with it. If the gripping handle is formed in a protruding shape and the gripping handle can be gripped by hand each time to fix the rice sharpening body, it becomes an extremely practical rice sharpening device. Mouth supplies water from faucet Only a prone position, and a convenient location becomes convenient When those to be formed by taking into consideration each other for gripping by hand the rice inlet. The specific example shown below is based on an embodiment incorporating this preferred configuration.

[0021]

Embodiment 1 As can be clearly understood from a perspective view showing the inside of FIG. 1 in a see-through manner, a longitudinal sectional view along the axis of FIG. 2, and a longitudinal sectional view orthogonal to the axis of FIG. , Rice sharpening body 1
Is a transparent plastics material, the bottom opening of which is formed in a cylindrical shape having a slightly smaller diameter than the upper end opening, and a large number of small drain holes 11 having a diameter of about 2 mm on its side surface.
11, ..., but in the rear end direction of the main body 1,
Further, in the tip end direction, the gap is gradually made denser, and thread grooves are formed at the upper end of the inner peripheral surface and the lower end of the outer peripheral surface of the main body 1, respectively.

Further, a cut-out hole having a diameter of about 2 to 3 cm is formed at an appropriate position near the upper end opening of the side of the rice-grinding main body 1, and the cut-out hole is made of rubber or synthetic rubber. A water supply port 12 is formed by fitting a funnel-shaped receptacle member formed in an elliptical or oval port in the axial direction, and the water supply port 12 is located on the left side (when the bottom of the rice sharpening body 1 is viewed forward). A funnel-shaped unit formed integrally with the main body 1 at a position where it is easy to grasp with the left hand (if the dominant hand is a right-handed person), which is also close to the left side) The rice input port 13 having the hole of the above is arranged side by side.
In addition, a grip handle 15 is protruded from the rice inlet 13 so that the formed cap 15 is slidably covered in the axial direction of the rice sharpening main body 1.

On the other hand, a reinforcing rib 16 is integrally formed in a cross shape at a bottom opening of the rice sharpening main body 1, and a shaft core supporting portion 17 having a female screw hole is realized at a center crossing portion thereof. Then, the base end of the shaft core material 2 is screwed, and the shaft core material 2 is disposed at the shaft center position of the rice sharpening body 1, and the distal elastic piece 21
However, a desired state is realized at about the center of the upper end opening of the rice sharpening main body 1.

The bottom cover 3 is screwed into the bottom opening of the rice sharpening main body 1 formed as described above using the screw groove at the same location. The bottom cover 3 is provided with drain holes 31, 31... Having a diameter of about 2 mm as a whole, and in combination with the drain holes 11, 11,. Thus, the function of efficiently discharging dirty water is achieved.

The screw groove formed on the inner peripheral surface of the upper end opening of the rice sharpening main body 1 is formed by projecting a cross shape on the back surface of the upper lid portion 4 and screwing an end thread of a reinforcing rib 41 formed. ,
The upper cover 4 is fitted. At this time, three stirring blades 51, 51, 51 are rotatably mounted on the upper lid part 4 at the tip end side, and a pipe-shaped operating rod 5 having a handle 55 attached to the upper end.
Is inserted and combined at its center in advance with a loose fitting portion 42 formed at the intersection of the reinforcing ribs 41, and the elastic piece 21 at the tip of the shaft core 2 is inserted into the hollow portion of the operating rod 5. Thus, the upper end opening of the rice sharpening main body 1 is screwed and closed while being made to be able to advance and retreat to the shaft core material 2.

The three stirring blades 51, 51, 51
As shown in the vertical cross-sectional view of FIG. 2, in any case, during the forward / backward movement of the operating rod 5, only when the forward movement is performed, the tip in the advancing direction in the advancing direction, that is, the tip on the opposite side to the bearing side is closer to the bearing part. The operation rod 5 rotates and tilts backward, so that the operating rod 5 can easily advance through the floating rice grains. When the retracting operation is performed, the operating rod 5 naturally spreads due to the resistance of the rice grains. A restricting wall portion 53 and a release wall portion 54 are formed before and after the shaft attachment portion 52 so as to return to a substantially orthogonal posture.

[0027]

According to the rice sharpener of the present invention having the above-described structure, after a predetermined amount of rice is put into the rice sharpening main body, the rice sharpening body has an appropriate side surface and a grip portion formed therein. Holding the handle, as shown in the side view of FIG.
In the sink sink, while holding the bottom lid side in an inclined shape with the lower side down, or want the water supply port below the faucet,
After inserting the outlet of the hose extending from the faucet into the water supply port,
Make sure to supply water continuously.

As described above, the rice-grinding main body is held at an angle, and the inner rice grains are kept in a state where they are not piled up and compacted by gravity due to gravity. Since it is easy to soar in the water of the rice sharpening body in a floating state, grasp the handle of the operating rod with a stirring blade with the other hand and move the operating rod forward and backward, and the stirring blade provided at the tip The operating rod forcibly and easily stirs and mixes the rice grains, makes the rice grains contact each other and the rice grains with the stirring blades and the operating rod, and removes rice bran and other dirt from all the rice grain surfaces, Department and / or
Alternatively, a so-called rice sharpening operation is performed in which the water containing the dirt is continuously washed away from the small drainage holes or narrow grooves provided in the rice sharpening body. In addition, at the time of this forward / backward operation, a proper rotation operation of rotating the handle around the operating rod shaft center can also be performed at the same time. When the forward / backward operation incorporating this operation is performed, the stirring effect is further enhanced, and the rice sharpening effect is improved. It is very convenient.

As described above, the sharpened juice containing dirt is sharpened with the clean water continuously poured from the water supply port during the rice sharpening operation. As a result, as in the conventional case, each time the water in the container becomes turbid, the sharpened juice becomes one by one. The inconvenience of having to change the water is surely eliminated, and even if it gets slightly wet with splashing water, there is no such thing as immersing your hands in water, making it extremely simple and reliable It will demonstrate the excellent feature of being able to grind rice.

If the drain holes or narrow grooves are formed on both the bottom lid and the side of the rice sharpening body, the drainage efficiency is increased, and contaminated water can be discharged more quickly. Or the drilling arrangement of the narrow groove,
Adjust the water supply condition as appropriate, such as gradually increasing the density in the direction of the tip or distributing it to a coarser one. Depending on the purpose, the rice grinding operation can be completed in a short time, or the rice grinding operation can be completed with an appropriate amount of water. It can be a practical rice sharpener.

Further, since the operating rod is provided with the agitating blades protruding therefrom, the effect of stirring and mixing by the operating rod advancing / retracting operation is extremely high. In addition, the agitating blades are moved during the advancing / retracting operation of the operating rod.
It is designed to rotate and tilt in the direction of the arrow only in the forward movement direction, so that the agitation effect does not decrease and the resistance increases especially during the forward and backward movement of the operating rod. The feeling of resistance in the operation stage (stage in which the stirring blade is pushed toward the bottom of the rice sharpening main body) can be reduced, and the rice sharpener can be used very easily.

On the other hand, after finishing the rice sharpening operation, the tip of the rice sharpening body is desirably placed on an appropriate vessel such as an inner pot or a bowl of a rice cooker, and the rice, which has been sharpened by opening or removing the bottom cover, is removed. It can be easily taken out, and the rice grains remaining in the rice sharpening body are sprayed around the body, so that water enters the inside through small drain holes or pores, and all the rice grains flow away and are easily taken out After that, if you add the appropriate amount of water to the container containing the finished rice, you will be ready to cook rice.

In particular, in the case of a rice sharpener as shown in the embodiment, the rice inlet 13 is provided exclusively, and the cap 14 is formed in a structure that can also be used as the grip portion 15. Since it is made to be able to be supported at a position away from the rice sharpening main body 1, the probability of wet hands with water supplied from the water supply port 12 is extremely reduced, so that the rice sharpening work becomes less troublesome and more mechanical. It will enable rice sharpening.

Further, the operating rod 1 is guided by the shaft core member 2 and has a configuration restricted by the loose fitting portion 42 of the upper lid portion 4. Since the reciprocating operation is realized, the rice grains inside can be stably stirred and mixed without variation, so that the rice can be sharpened reliably, and the incorporation structure in the rice sharpening body 1 is simple,
It is easy to manufacture and makes it possible to realize an inexpensive rice sharpener.

As described above, the rice sharpener of the present invention enables simple and efficient rice sharpening work, and has a relatively simple structure, so that it can be manufactured easily and inexpensively. Many housewives who have been content with old-fashioned rice-sharpening work are reluctant to do so, and even young housewives, singles, and single employees who have avoided rice food because of the troublesome work of rice-sharpening are easy to use. It is highly valued and has the potential to be widely adopted, is a staple food that is familiar to most people, and has contributed greatly to the spread of cooked rice that is being re-evaluated as a well-balanced staple food here It is expected that this will halt the declining consumption of rice and bring back the vitality of Japan's main industry, agriculture.
