Description

[Detailed Description of the Invention] The present invention relates to a rice bowl in which rice stored at the bottom can be taken out from a rice outlet provided at the top.

Numerous inventions and ideas regarding rice racks have been made in the past, but all of them have a structure in which rice is taken out from an outlet provided at the bottom of the rice rack by utilizing its own weight.

For this reason, even if the rice bowl is quite large, you will have to be reluctant to remove the rice from the outlet, especially if the rice bowl is placed inside a kitchen appliance such as a sink or cooking table. It was not possible to take out the product, making it extremely inconvenient for a household item that is used relatively frequently.

As shown in Fig. 4, this conventional product is provided with an inclined plate 50 which is inclined from the top of the rice box toward the outlet 49 at the bottom.
The rice stored in the rice rack is guided to the outlet 49, a temporary storage section 51 is provided in the middle, and a lever (not shown) attached perpendicular to the plane of the paper is rotated with respect to the temporary storage plate 52. The inlet 54 is blocked by the partition plate 53 and the outlet 49 is blocked at the same time.
The most common structure is to take out a certain amount of rice from the temporary storage section 51, but in this case, a dead space 55 inevitably occurs behind the inclined plate 50, resulting in poor storage efficiency. there were.

Furthermore, as a measuring device, several types of cages with different capacities are installed in advance, and rice is put into the desired cage by pressing a button and operating a lever that is attached to each cage. If there is no container with the desired capacity, a device can be installed that achieves the purpose by using a combination of containers with different capacities. It had the disadvantage that it was not possible.

The present invention was made in order to overcome the drawbacks of the conventional products as described above.

Next, one embodiment of the present invention "11" will be explained in detail with reference to FIGS. 1 to 3.

1 is a side plate made of sheet metal with a U-shaped cross section;
As shown in the figure, three side walls 2, 3.4 are arranged in a row, and the lower edge of each side wall 2, 3.4 is bent inward.

Reference numeral 5 designates a top plate made of sheet metal having an inlet 6 and a lid 7, and the peripheral edge of the side plate 1 other than the portion corresponding to the front opening 8 is bent downward to cover the button side plate 1 from above. It is designed to be crowned.

In addition, the bottom plate 9 made of sheet metal and made of a flat plate is in contact with the side plate 1 and the front plate 10 from below, and is bent inwardly into each of the side walls 2, 3, 4 with screws. 1
1 is stopped.

12 is a cylindrical body, and at the bottom of the cylindrical body 12, an inlet 14 having a rice inlet 13 extends laterally, and an outlet 16 having a slightly downwardly sloping bottom 15 is cylindrical. An outflow port 17 is provided that extends to the upper side of the body 12 and is oriented so that the rice flows out in a direction substantially perpendicular to the direction in which the inflow portion 14 extends.

Reference numeral 18 denotes a screw built into a cylindrical body 12 consisting of a shaft 19 and wings 20 spirally protruding around the shaft. It is connected to the shaft of a motor 24 housed in an angular motor housing 23 provided separately from the body 12 .

The size of the screw 18 is such that the blade 20 is the same as or slightly smaller than the inner diameter of the cylindrical body 12.

The cylindrical body 12 is inclined along the side wall 2 and an inclined upper plate 25 (described later) so that the upper part is attached to the front of the rice rack and the lower part is attached to the rear of the rice rack. One end of the fixture 26 is welded to the side wall 2, and the other end is welded to the inclined upper plate 25 or the inclined lower plate 27.

28 and 29 are also inclined lower plates, and the rice storage section 3 is formed by another inclined lower plate (not shown), the inclined upper plate 25, and the side plate 1.
0 is formed.

The front plate 10 is a box-shaped body integrally molded from synthetic resin, and when the rice rack is assembled with other members, it forms the side walls, bottom plate, and top plate at the front of the rice rack.

Reference numeral 31 denotes a container placement part provided on the front plate for placing a container for receiving the rice flowing out from the outlet 17 of the cylindrical body 12, and the container placement part 31 has a hole into which the rice can be introduced. It consists of a top plate with holes 32, two side walls, and a bottom, and the front is opened to form a container outlet 33.

Furthermore, a box body 35 is attached to the back surface of the upper inclined part 34 of the front plate 10, and a sliding part into which the body of the IT-shaped rice amount setting knob 436 can be fitted and slid is attached to the inclined part 34. A groove 37 is bored, and a square column-shaped weight body 38 is formed at the lower end as shown in FIG.
The upper end of the linear body 39 made of a piano wire having 37
It is connected to a knob 36 fitted into the.

A measuring device 48 is constituted by the knob 36, the sliding groove 37, the weight body 38, the linear body 39, and a limit switch 45, which will be described later.

The upper and lower ends of a steel braking plate 42, which is curved in an arc shape with a convex front central portion, are fixed to the upper and lower front ends of the weight body 3B, respectively, and the vertical center of the side strips of the weight body 38 are fixed to the upper and lower ends of the front surface of the weight body 3B. A pinion 43 is rotatably attached, and the pinion 43 is engaged with a rack 44 fixed to the bottom of the front collapse plate 10, and the rack 44, the pinion 43, and the brake plate 4
2 constitutes a braking device 47 that allows the weight body 38 to descend at a constant speed without accelerating when it descends due to its own weight after being pulled upward.

If the distance that the cone 38 moves in the vertical direction is very long,
The degree of braking of the cone 38, which is descending due to its own weight, must be controlled as it goes downwards, but a braking device such as the one in this example is sufficient for practical use if the distance required for a normal rice bowl is to be moved. It's something you get.

A limit switch 45 connected to the motor 24 is mounted and fixed on the bottom of the front plate 10 directly below the rack 44, and when the weight body 38 is not measuring, the bottom volume of the weight body 38 comes into contact with the limit switch 45, and the motor is turned off. 24 is turned off.

In addition, 46 is a steel sliding plate attached to the front plate 10 over the range in which the weight body 38 moves in the vertical direction,
As shown in FIG. 3, the sloped portion 34 of the front plate 10 is marked with a scale representing the amount of rice.

In this embodiment ψ11, the materials of the side plate 1, @face plate 10, etc. were appropriately used, but the materials of each member in the present invention are changed as necessary and are not specified in any way.

To use the rice bowl configured as described above, first remove the lid 7 of the top plate 5, and put rice into the storage section 30 from the inlet 6. Rice will be guided by the inclined upper plate 25, inclined lower plate, etc. The initial rice enters the inlet 14 from the inlet 13 provided at the bottom of the cylindrical body 12, and then enters the sufu I built in the cylindrical bodies 1 and 2.
Reach the bottom of J--18.

Once a predetermined amount has been added, place a transparent container on the container placement part 31 of the front plate 10 in advance, grasp the rice amount setting knob 1+36 of the measuring device 48, and slide it along the groove 3T. When it is set to the part of the scale that indicates a predetermined amount of rice, the weight body 38 that was in contact with the limit switch 45 moves to the filament body 39.
, the coupling 2
1 and the flow speed gear 22, the rotation is caused by the screw shaft 19
The rotation of the screw 18 is started.

When the screw 18 rotates, the cylindrical body 12 and the screw 1
The rice existing between B begins to move upward along the wings 20 that protrude in a spiral around the axis, and the rice reaches the cylindrical body 12.
When it reaches the outflow part 16 extending to the upper part of the cylindrical body, it flows out to the side of the cylindrical body through the outflow port 17 and passes through the hole 32 bored in the top plate of the container mounting part 31 of the front neck plate 10. It fits inside the container.

During this time, the rice stored in the storage section 30 passes over the inlet 13 of the cylindrical body and flows into the inflow section 14 one after another due to its own weight, and is similarly moved upward.

On the other hand, the weight body 38 that has been pulled upward starts to descend due to its own weight immediately after the gripped rice amount setting knob 36 is released. It descends at a constant speed without accelerating due to the sliding movement with the sliding plate 46 of No. 10, and the action of a braking device 47 consisting of a pinion 43 and a rack 44 in substantially the lower half of the rice rack. continue.

After that, when the time required for a predetermined amount of rice to flow out into the container from the outlet 17 has elapsed, the bottom of the weight body 38 comes into contact with the limit switch 45, the current to the motor 24 is cut off, and the rotation of the screw 18 is automatically started. After that, the rice is stopped and the measurement of the rice is completed, and then the container is taken out from the container outlet 33.

The scale for the amount of rice is based on the assumption that the motor 24 starts rotating when the inside of the cylindrical body 12 is filled with rice up to just below the outflow part 16. If rice is not filled, there will be a slight discrepancy between the set amount of rice and the actual amount taken out.

Therefore, in such a case, for example, if you want to take out a predetermined amount of rice after putting rice into a completely empty rice bowl, rotate the motor 24 by adjusting the tip of the knob 36 to the part of the scale that represents the minimum amount. Fill the tubular body 12 with rice up to just below the outlet 16, or set the knob 36 to an appropriate amount scale, and then forcefully turn the knob 36 at an appropriate time while paying attention to the amount of rice that is filling the cylindrical body 12. It is necessary to stop the rotation of the motor 24 by sliding the weight body 38 against the limit switch 45.

In this implementation-1, the rice amount setting knob i+36 is designed to double as a motor operation switch, but a separate switch for operating the motor may be provided between the limit switch 45 and the power source. .

However, in this case, it is preferable to use a so-called self-holding circuit in which the operating switch is turned off in conjunction with the contact of the weight body 38 with the limit switch 45.

The advantages of the rice bowl of the present invention are particularly obvious when it is placed inside a kitchen appliance such as a sink or cooking table, but there is no limitation on the place where it can be placed.

The rice rack of the present invention consists of a cylindrical body with a rice inlet at the bottom and an outlet at the top, and a mechanism built into the cylindrical body that rotates to move a predetermined amount of rice from the inlet to the outlet. Since it is equipped with a screw to take out the rice, the rice removal port can be provided at the middle or higher part of the height of the rice box, and there is no need to take an unnatural posture such as a middle position when taking out the rice. On the other hand, it has the advantage of having little dead space and good storage efficiency.

In addition, the rice rack of the present invention has a measuring device that can control the rotation time of the screw based on the falling time of the weight that has been raised to a predetermined height. Fine measurements are also possible.

In addition, if the weight body is connected to the rice amount setting knob by a flexible linear body, the vertical direction of the weight body and the moving direction of the rice amount setting knob must be in the same direction. The weighing device is made smaller.

In addition, a weighing device equipped with a braking device that allows the weight to descend at a constant speed has a wide measuring range, and it is easy to set the scale of the rice quantity setting knob, making it easy to manufacture the measuring device.
