DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice bin, and more particularly, to a rice bin capable of storing milled rice and measuring and discharging the stored rice by a predetermined amount.

[0002]

2. Description of the Related Art Conventionally, in general households, polished rice is stored and stored in rice bottles, and a necessary amount of rice is taken out of the rice bottles and used for food. .

[0003] For this reason, rice bins used in ordinary households and the like are usually prepared by measuring stored rice in a fixed amount.
It is being leaked.

That is, generally, in such a rice bin, polished rice is stored on the upper side,
While a rice storage room having an outlet through which the stored rice is discharged is provided, a fixed amount (for example, 1 go) of rice is measured and stored in a lower portion of the rice storage room. Trout,
It is arranged so that it can slide in the front and rear direction of the rice bin,
Further, an operation lever that is operated from the outside and moved up and down to perform the sliding movement of the mass is provided on the front panel and configured. Then, in the normal state, the operation lever is positioned at the upper side, and the trout is arranged behind the rice bin, and in such an arrangement state, rice is supplied from the rice storage room into the trout through the discharge port. Then, a certain amount of rice is weighed, and by pressing down the operation lever, the trout is pulled out to the front side of the rice bin, and a certain amount of rice contained in the trout is removed. It is designed to be able to flow out from the outlet provided on the front side.

However, in the conventional rice bin having such a structure, in order to improve the operability, a spring or the like which exerts a biasing force on the operation lever in a direction opposite to the pressing direction thereof is used. Means are attached, whereby the operating lever is pushed down with a finger to drain the rice contained in the trout, and then the operating lever is automatically returned to its original position simply by releasing the finger from the operating lever. At the same time, the trout is pushed back to the original rear position, and a certain amount of rice is again supplied and weighed into the trout after the rice is drained. However, if the operation lever is pushed down and the finger is separated from the operation lever for some reason while rice is flowing out of the trout, the trout leaves rice inside the trout. Rice as it is One pushed back to the rear of, thereby, is of no longer able to flow out all rice in mass. In such a case, since the rice is immediately supplied into the trout pushed back to the back of the rice bin, it is impossible to remove only the rice remaining in the trout. .

[0006] In short, in the conventional rice bin, the operator simply presses down the operation lever with his / her finger and then releases the finger from the operation lever without performing any special operation for measuring a certain amount of rice. By performing only the operation of discharging the measured rice, the measured rice is taken out, and a certain amount of rice is measured, so that excellent operability can be exhibited. On the other hand, there is a very serious disadvantage that the amount of rice to be taken out may vary due to the difference in the time between pressing down the operating lever and releasing the finger.

[0007]

Here, the present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to perform any special operation for measuring a certain amount of rice. By simply performing the operation of discharging the weighed rice, the weighed rice can be taken out, and excellent operability such that a certain amount of rice can be weighed can be exhibited. The object of the present invention is to provide a rice bin in which the amount of rice can always be accurately and reliably made constant.

[0008]

According to the first aspect of the present invention, in order to solve the above problem, (a) the milled rice is stored and the stored rice is stored A rice storage room provided with a discharge opening for discharging, and (b) an opening portion which is rotatably arranged below the discharge opening of the rice storage room, has a certain volume, and opens to the outside. A rotating body having a plurality of rice storage chambers arranged around a rotation axis; and (c) an upper part arranged to cover the periphery of the rotating body and communicated with an outlet of the rice storage chamber. And a lower window opening downward, and the openings provided in the plurality of rice storage chambers at portions other than the upper and lower windows, respectively. A cover for closing the part, and (d) the rotating body is moved in one direction by an operation from outside. Of the plurality of rice storage chambers, only the opening of one of the rice storage chambers is made to correspond to the upper window of the cover. While the rice is introduced and stored from the outlet of the rice storage room through the window, only the opening of another rice storage room is made to correspond to the lower window of the cover, and the other Operating means for positioning the rotator at a rotation position at which the rice stored in the other rice storage chamber is discharged from the one rice storage chamber through the opening and the lower window portion. The feature is the rice bin composed of

The rice is introduced and stored from the rice storage room, while only one other rice storage room is made to correspond to the lower window of the cover at the opening thereof, and the other rice storage room is opened. From a place where the rotator is positioned at a rotation position where the rice stored therein is discharged from the two rice storage chambers,
By performing a single operation of rotating the rotating body to such a rotating position through the operating means, rice is supplied into the one rice storage room, and a certain amount of rice according to the volume of the rice storage room is obtained. At the same time as being weighed, a certain amount of rice according to the volume can be discharged from the other rice storage chamber.

[0010] Further, in such a rice bin, since the rotating body can be rotated in only one direction, the rice remains in the rice accommodating room while the rice is being discharged in any situation. The rotation of the body in the opposite direction to the one direction can advantageously be avoided, and the rice receiving chambers other than those whose openings correspond to the upper window and the lower window of the cover. The opening is closed by the cover, so that rice is supplied to a plurality of rice storage chambers at the same time, or rice is discharged from the plurality of rice storage chambers at the same time. What you do
Can be effectively prevented, and as a result,
From each of the rice storage rooms in which rice is stored, the entire amount of the stored rice can be sequentially discharged one by one according to a certain order according to the rotation direction of the rotating body, and no rice is stored therein. A fixed amount of rice according to a fixed volume of each rice storage room can be supplied to each of the unstored rice storage rooms one by one according to the predetermined order.

Therefore, in the rice bin according to the first aspect of the present invention, the rotating body is simply rotated by a predetermined amount without performing any special operation for measuring a fixed amount of rice. By performing only the operation of discharging the measured rice by simply rotating the rice to the position, the measured rice can be taken out and a certain amount of rice can be measured at the same time, and excellent operability is extremely effective. In addition, the amount of rice taken out can always be accurately and reliably set to a constant amount.

According to a second aspect of the present invention, in the rice bin according to the first aspect, the operating means includes a handle member which is turned by an external operation. And a motion transmitting mechanism for transmitting the rotating motion of the handle member to the rotating body and rotating the rotating body in the one direction. When such a configuration is adopted, the rotating body can be rotated with a simple operation of simply rotating the handle member, and a fixed amount of rice can be obtained without a complicated operation.

In the rice bin having such a configuration, the rotator can be reliably rotated in only one direction with a general-purpose and relatively simple structure.

According to a fourth aspect of the present invention, in the rice bin according to the second or third aspect, the operating means is operated by one rotation of the handle member. Accompanying this, among the plurality of rice storage rooms, while the rice is introduced only into the one rice storage room, the rotational position of the rotating body in which rice is discharged only from the other one rice storage room, It is characterized in that it is provided with a rotation width restricting means for restricting the rotation width of the handle member so that the rotation of the rotating body is stopped. In the rice bin according to the present invention, the rice is supplied from the rice storage chamber to only one of the plurality of rice storage chambers by rotating the handle member once, so that a certain amount of rice is more reliably provided. And the entire amount of rice contained therein can be discharged more reliably from only one other rice storage chamber, so that with a quick operation, a certain amount of rice can be more efficiently discharged. It can be more accurately and reliably taken out.

Further, in the invention according to claim 5 of the present invention, in the rice bin according to any one of claims 2 to 4, the operating means includes: It is characterized in that it is provided with a reverse rotation prevention device for preventing the rotation of the handle member from being reversed in the middle of the rotation of the handle member in the direction of rotating in one direction. According to such a configuration, the handle member can be reliably rotated by the predetermined rotation amount, and the rotating body can also be rotated by the predetermined rotation amount in one direction, so that the plurality of rice storage chambers can be rotated. Among them, while the rice is introduced into only one rice storage room, the rotating body can be more reliably positioned at the rotation position where the rice is discharged only from the other one rice storage room, and as a result, As a result, a certain amount of rice can be more reliably weighed and more accurately extracted.

Furthermore, in the invention according to claim 6 of the present invention, in the rice bottle according to claim 5 described above, the reverse rotation preventing device can approach and separate from the handle member. And at the end point of rotation of the handle member in a direction for rotating the rotating body in one direction, the engagement member is separated from the handle member while the handle member is engaged.

The openings 44 are sequentially assigned one by one to the upper windows 38 of the two drum covers 26 and 28, and the openings 44 are provided only in the rice accommodating chamber 44 corresponding to the upper windows 38. And upper window 3
8, the rice stored in the rice storage room 18 is discharged from the outlet 20 of the rice storage room 18 in a fixed amount (here, the amount of one unit) according to the volume of the rice storage room 48. Introduced,
The rice accommodating chamber 4 which is adapted to be accommodated and which is located on the rear side in the rotation direction of the rotary drum 42 with respect to the rice accommodating chamber 48 having the opening 44 communicated with the discharge port 20.
The openings 44 of the eight drums 28 correspond to the lower openings 40 of the two drum covers 28, 28, and only the rice storage chamber 48 corresponding to the lower openings 40 has the openings 44 and the lower portion. Through the side window 40, a certain amount of rice stored in the rice storage chamber 48 is discharged, and the rotating drum 42
Is accommodated in the rice receiving bucket 25 arranged below the rice receiving bucket 25.

Therefore, in the rice bin 10 according to this specific example, the knob 104 of the lever 90 is gripped,
Only by performing a single operation of pushing this down to the lower end of the operation hole 108, a certain amount of rice can always be accurately and reliably taken out, and a certain amount of rice can be accurately measured. The operability and the extremely high reliability of weighing can be fully exhibited.

In the rice bin 10, an upper stopper 110 and a lower stopper 112 are provided in the operation hole 108, and the two stoppers 110, 112 vertically move the tip of the arm portion 94 of the lever 90. The width of the movement, that is, the rotation width of the lever 90 is regulated, so that the rotation drum 4
2 is rotated by 1/3 turn in one direction (the clockwise direction in FIG. 19) about its central axis. One opening 44 of the rice storage chamber 48 is connected to the upper window 38 and the discharge port 20, and another opening 44 of the rice storage chamber 48 is connected to the lower window 40.
, Respectively, so that a certain amount of rice can be more accurately and reliably extracted with a quick operation.

Further, in the rice bin 10, three engaging claws 64 of the ratchet wheel and cap 58, which are rotatably attached to the rotary drum 42, and the rice wheel 10, which is rotatable. Attached and lever 9
Geared cap 60 that rotates with the rotation of zero
Since the ratchet mechanism is configured to rotate the rotary drum 42 only clockwise in FIG. 19 around the center axis thereof between the three engaging claws 84 of the ratchet wheel 80 built in With the rotation of the lever 90, the rotating drum 42
There is an advantage that it can be more reliably rotated in only one direction.

Further, in the rice bin 10 according to this example, the rotating drum 42 is moved around its central axis in FIG.
Lever 90 in the direction to rotate 1/3 turn clockwise
During rotation of the lever 90, the rotation direction of the lever 90 can be prevented from being reversed.
During the pivoting operation of the rotating drum 42, the above-mentioned predetermined amount of rotation of the rotating drum 42 can be advantageously secured, whereby rice is more reliably introduced into only one rice storage chamber 48, and Rice can be drained only from the other one of the rice storage chambers 48, so that a certain amount of rice can be extracted more accurately.

In the specific example, the knob 104 attached to the tip of the lever 90 is moved up and down from the outside, whereby the entire lever 90 is rotated, and the rotary drum 42 is rotated with a predetermined rotation amount. Instead of the lever 90, a handle rotatable around the central axis is provided, and the handle is directly rotated from the outside to rotate the rotary drum 42. You may do it. In addition,
20 to 23 showing this specific example and FIGS. 24 and 25 showing still another specific example different from this specific example, the members and parts having the same structure as the specific example will be described below. In the drawings, the same reference numerals as those in the above-described specific examples are given, and the detailed description thereof is omitted.

More specifically, for example, as shown in FIGS. 20 to 23, the handle 138 is arranged on the outer surface of the front panel 22 of the main body 12, while the handle 138 is arranged on the inner surface of the front panel 12. A large-diameter handle gear 140 meshed with the gear portion 72 of the cap with gear 60 is disposed coaxially with the handle 138 at a position corresponding to the above. Further, the handle 138 and the handle gear 140 are connected to each other by connecting bolts 142 penetrating through the front panel 22 and disposed along the central axis thereof, so that the front panel 12 can rotate integrally.
To each.

Then, as shown in FIG. 20, by operating the handle 138 from the outside, the tip of the arrow drawn on the handle 138 points to “stop” drawn on the front panel 12 in FIG. By rotating clockwise from the position to a position indicating “discharge”, the geared cap 60 is rotated counterclockwise in FIG. 21, and thereby the ratchet wheel 80 built in the geared cap 60 is rotated. Are engaged with the respective engaging claws 64 of the ratchet wheel and cap 58 rotatably attached to the rotating drum 42 so that the rotating drum 42 rotates counterclockwise around its central axis. It may be made to rotate by 1/3 turn in the direction.

Thus, with the rotation of the handle 138, the openings 44 of the three rice accommodating chambers 48 of the rotating drum 42 are sequentially brought into correspondence with the upper window 38 one by one. Rice storage room 4 corresponding to window 38
The rice stored in the rice storage chamber 18 is supplied only from the discharge port 20 of the rice storage chamber 18 by a certain amount only in the inside of the rice storage chamber 4, and the opening 44 communicated with the discharge port 20 is opened. The opening 44 of the rice storage chamber 48 located on the rear side in the rotation direction of the rotary drum 42 with respect to the rice storage chamber 48 corresponding to the lower opening 40 of the two drum covers 28, 28. Rice storage room 48 corresponding to opening 40
Only from this, a certain amount of rice stored in the rice storage chamber 48 is discharged and stored in the rice receiving bucket 25 disposed below the rotating drum 42.

Therefore, in the rice bin 139 according to this embodiment, as in the above-described embodiment, the rice can be discharged and measured at once by simply performing a single operation of rotating the handle 138. Thus, excellent operability can be effectively exhibited, and the amount of rice discharged can always be accurately and reliably set to a constant amount.

In this specific example, the tip of the arrow drawn on the handle 138 is only within the range from the position indicating “stop” to the position indicating “discharge” drawn on the front panel 12. The inner surface of the front panel 12 is provided with two inwardly protruding protrusions 144 at a predetermined interval so that the rotation of the front panel 12 is performed. Of the engaging piece 1 engaging with the projection 144
Two 46 are provided at the same interval as the arrangement interval of the two projections 144.

Thus, even in the rice bin 139, the opening 44 of one of the three rice accommodating chambers 48 is opened by the rotation of the handle 138.
The opening 44 of the rice accommodating chamber 48 can be more reliably corresponded to the lower window 40 with respect to the discharge port 20 and the other rice storage chamber 48, respectively. Thus, a certain amount of rice can be more accurately and reliably extracted.

In the specific example, only one rotary drum 42 is provided in the main body 12, and three rice accommodating chambers 48 having the same volume are provided for the rotary drum 42. However, while providing a plurality of rotating drums,
It is also possible to make the volumes of the rice accommodating chambers provided in the respective rotating drums different from each other.

That is, as shown in FIGS. 24 and 25, the rotary drum 42 similar to the above-described embodiment and the three rice accommodating chambers 148 provided with the same structure as the rotary drum 42 are provided. A large rotating drum 150 having a volume twice as large as the rice accommodating chamber 48 of the rotating drum 42 (that is, a volume capable of accommodating two-piece rice) is placed below the rice storage chamber 18 in the main body 12. Are coaxially arranged in a state of being serially arranged in the width direction of the main body 12 with the bottom wall portions facing each other. The drum support projections 14 integrally projecting from both surfaces of a drum support plate 152 erected between the two rotary drums 42 and 150 are provided.
9a, 149a and both side panels 52 of the main body 12;
52, drum support projections 149 formed integrally with each inner surface
b and 149b, the rotary drum 42 and the large rotary drum 150 may be independently rotatably mounted around their central axes.

In this case, the rice storage room 18
Are formed in correspondence with the positions of the two rotating drums 42 and 150.
At the opening portions of the two rotating drums 42 and 150, which are open outward in the axial direction, the ratchet wheel caps 58, 58 are respectively attached so as to be integrally rotatable. Is mounted rotatably, and the cap with gear 60 is rotatably attached to the drum supporting projections 149b, 149b provided on the side panels 52.

Particularly, in this specific example, the gear 154 has a substantially cylindrical shape as a whole, and has a gear 154 at one end in the length direction.
, And two shaft covers 155a, 155 each formed integrally with an engagement piece 153 extending radially on both sides at the other end.
55b, each gear 154 is connected to the geared caps 60, 6
In a state where the gears 72 are engaged with the respective gear portions 72, they are rotatably inserted and disposed at both ends of the lever rotation shaft 106, respectively. In addition, the lever rotation shaft 106
There are three levers 156, 158, 160
Are rotatably mounted in a state of being sequentially arranged in the longitudinal direction of the rotating shaft 106.

At this time, the levers 156 arranged on both sides in the longitudinal direction at the intermediate portion of the lever rotation shaft 106 are used.
And the lever 160 are provided with engaging projections 162 and 166 integrally formed on their sides, respectively, with engaging pieces 153a and 153 of the shaft covers 155a and 155b corresponding to the respective arrangement sides.
It is arranged in a state of being engaged with the upper part of b at the rear side of the main body 12. In addition, the rotating shaft 10 for the lever
The lever 158 disposed at the center of the shaft 6 has an engagement protrusion 164 integrally formed below the lever 158 with respect to a lower portion of each of the engagement pieces 153a and 153b of the two shaft covers 155a and 155b. , In a state of being engaged on the front side of the main body 12.

Thus, by gripping the knob 104 provided at the distal end of the lever 156 and rotating it so as to push it down toward the user in FIG. 29, the engaging piece 153a is formed by the engaging projection 162. Is pressed to rotate only the shaft cover 155a of the lever rotating shaft 106 disposed on the side where the rotary drum 42 is disposed, and with the rotation, the rotation is meshed with the gear 154a of the shaft cover 155a. The cap with gear 60 on the side of the drum 42 is rotated, so that the rotating drum 42 is rotated by only 1/3 turn in only one direction opposite to the direction of rotation of the cap with gear 60. I have.

Further, by rotating the lever 160 in the same manner as the lever 156,
, The engagement piece 153b is pressed, and only the shaft cover 155b is rotated. With this, the geared cap 60 on the large rotary drum 150 side meshed with the gear 154b of the shaft cover 155b is rotated. Thus, the large-sized rotary drum 150 can be rotated by only 1/3 rotation in one direction opposite to the rotation direction of the geared cap 60.

Further, the two levers 156, 16
In the same manner as in FIG. 0, by rotating the lever 158, the two engagement pieces 153a, 1
53b are pressed together and the two shaft covers 155a, 1
55b are rotated, and the geared caps 6 on the rotary drum 42 side and the large rotary drum 150 side are thereby rotated.
0 and 60 are simultaneously rotated so that the two rotating drums 42 and 150 are both rotated by 1/3 turn.

Thus, when the lever 156 is rotated, one set of rice according to the volume of the rice accommodating chamber 48 of the rotary drum 42 is produced, and when the lever 160 is rotated, When the lever 158 is further rotated when the two sets of rice that match the volume of the rice storage chamber 148 of the large rotary drum 150 are further rotated, the volume of the rice storage chamber 48 of the rotary drum 42 and the capacity of the large rotary drum 150 The three sets of rice corresponding to the combined volume of the rice accommodating chamber 148 can be reliably weighed and accurately discharged.

Accordingly, in the rice bin 168 according to this example, one of the three levers 156, 158, and 160 is selected and operated, so that one operation can be performed by one operation.
Any amount of rice in 2 go, 3 go can be taken out,
Thus, superior usability can be exhibited extremely effectively. Also, of course, in such a rice bin 168,
Since the configuration is similar to that of the specific example except that the number of rotating drums and the number of levers are different, the same effects as those of the specific example can be very effectively enjoyed.

Here, in the above three specific examples, the rotating drums 42 and 150 constituting the rotating body are configured to have a cylindrical shape with one side closed, but the shape of the rotating body is not limited to this. It is not something to be done.

Further, the shape of the rice accommodating chamber provided in the rotating body and the shape of the cover arranged to cover the periphery of the rotating body are not limited to those shown in the above-mentioned specific examples. No, depending on the shape of the rotating body, etc.
It can be determined as appropriate.

Further, the shape of the opening formed in each rice accommodating chamber and the position of the opening are not limited to those shown in the above-mentioned specific examples, and the cover disposed over the rotating body is not limited. And the formation positions of the upper window portion and the lower window portion formed on the cover, and the like, respectively.

Further, in the above three specific examples, the inner space of the rotating drums 42 and 150 as such a rotating body is divided into three equal parts in the radial direction, and is adjacent to each other around the rotation axis of the rotating drums 42 and 150. The three arranged spaces are configured as the rice storage chambers 48 and 148, respectively. However, if the rice storage chamber is disposed around the rotation axis with respect to the rotating body, the rice storage chamber is configured as the rice storage chamber. The arrangement form is not particularly limited. Therefore, even if it is arranged along the rotation axis direction with respect to the rotating body, there is no problem at all. However, a case where a plurality of rice storage chambers are arranged so as to be stacked from the inside to the outside around the rotation axis is excluded.

Further, it is needless to say that the structure of the operating means is not limited at all as shown in the specific example.

[0077]

As is clear from the above description, in the rice bin according to the present invention, the rotating body is simply rotated by a predetermined amount without performing any special operation for measuring a fixed amount of rice. By performing only the operation of discharging the weighed rice, which is simply rotated to the position, the weighed rice can be taken out and at the same time a certain amount of rice can be weighed,
Excellent operability can be demonstrated extremely effectively,
In addition, the amount of rice to be taken out can always be accurately and reliably set to a constant amount.
