[0005]

The conventional rice cooker as described above is constructed so that water in the water storage tank 5 is supplied to the rice cooker 7 by the water supply device 6 to cook rice. Therefore, not only is piping work required to prevent water leakage, but also a water storage tank 5 is required to store water for at least one batch of rice, making the overall structure of the rice cooking device that much more complex and large. It will take shape. In addition, there is a problem in that sanitary measures such as measures to prevent the growth of mold and bacteria must be taken into account regarding the water stored in the water storage tank 5. Furthermore, since the amount of water in the rice cooker 7 does not necessarily match the amount of rice, the rice may be cooked differently depending on the day, such as being too soft or too hard.

The present invention was made to solve the above-mentioned problems, and it is possible to make the entire device compact without using a water storage tank or a water supply device, and to make it sanitary and to produce an appropriate amount of rice. The purpose of the present invention is to realize a rice cooking method and device that cooks rice with a high amount of water and has high cooking accuracy.

[0007]

[Means for Solving the Problems] The present invention uses a calculation means to calculate the amount of rice corresponding to the amount of water in the rice cooking pot measured by a weight measuring means, and then transfers the calculated amount of rice to a dry rice polishing unit. This method adopts a rice cooking method in which the rice is poured into a rice cooker and cooked while being measured using a weight measuring means.

[0008] Also, it consists of a rice polishing section that removes the bran from the rice, and a rice cooking section that cooks the polished rice inputted from the rice polishing section, and the water and rice put in the rice cooking pot of the rice cooking section are combined. A weight measuring means for measuring weight, a calculation means for calculating an appropriate amount of rice corresponding to the amount of water measured by the weight measuring means, and a weight measuring means for calculating the amount of rice polished in the rice grinding department and added to the rice cooking pot. The rice cooking device includes a control section that controls the amount of rice according to the calculation result of the calculation means while measuring the amount of rice.

[0009]

[Operation] When you put the approximate amount of water required for cooking rice into the rice cooker and set it, the weight measuring device will measure the amount of water. The measured amount of water is sent to a calculator, which calculates the appropriate amount of rice corresponding to the amount of water. At the same time, the rice grinding section is driven to grind the polished rice in a dry state, and the ground rice is added to the rice cooker one after another while being measured by a weight measuring device. When the input amount of polished rice matches the amount of rice calculated by the calculator, the controller stops inputting the polished rice from the rice polishing section and starts the rice cooking operation.

In addition, although not shown, a seal is provided between the rice polishing section 3 and the rice cooking section 7 to prevent the rice polishing section 3 from being affected by heat and steam accompanying rice cooking in the rice cooking section 7. ing.

Next, the operation of the present invention will be explained with reference to the flowchart of FIG. Rice 16 before being polished is supplied in advance from the supply port 48 of the rice polishing section 3, and stored in the rice bin section 2 in a piled manner from the inclined surface at the bottom. For example, while looking at the scale 71 and numerical value 72 of the rice cooking pot 70 taken out from the main body 1, turn on the tap and pour an approximate amount of water 17 corresponding to the amount of rice to be cooked into the rice cooking pot. Set it to 7 (step 1...the rest is omitted). When the rice cooker 70 is set, the weight measuring device 73 works to measure the total weight W.
x is measured and the measured value is sent to the control unit 80. The control unit 80 subtracts the tare weight Wo of the rice cooker 70 from the total weight Wx,
Calculate the weight of water Ww = Wx - Wo. Also, based on this calculation result, the following calculation formula, Ws=N×Ww(
(N is a constant), that is, a standard appropriate amount of rice Ws corresponding to the weight Ww of water is calculated.

At this point, the electric motor of the rice polishing section 3 is driven, and the outer cylinder 41 supported by the lower and upper bearings 34 and 47 begins to rotate via the driven pulley 46. When the outer cylinder 41 rotates and the intake port 43 faces the regulation plate 36, spring pressure is applied to the rice 16 near the entrance of the intake port 43. As a result,
The rice 16 is forced into the rice polishing chamber R2 through the intake port 43 and pushed upward. The rice 16 that was pushed up was
Due to the change in the gap between the rotating hexagonal outer cylinder 41 and the fixed circular inner cylinder 42, the rice moves in irregular directions and is stirred as it rises in the polishing chamber R2. The rice 16 on the way up comes into contact with the inner cylinder 42, and part of it fits into the slit 44, and the bran is scraped off by the sharp opening edge of the slit 44. Furthermore, the rice bran layer is peeled off from the surface when the rice 16 in the rice polishing room R2 rub together. Then, the bran fraction 18 containing small dust and the like passes through the slit 44, falls down the separation chamber R3, and is collected in the bran tray 8. The rice 16 from which the bran has been scraped off is further polished by the mesh 45 of the outer cylinder 41, pushed up to the upper part of the rice polishing chamber R2, and successively introduced into the rice cooker 70 of the rice cooker 7 through the upper input port 11.

Meanwhile, during this time, the weight measuring device 73 detects the total weight Wx of the rice cooker 70 including the rice 16 and water 17 being put in, and outputs it to the control section 80. The control unit 80 is
The input amount Wr=Wx-(Wo+Ww) of 6 is calculated, and this value Wr is compared with the appropriate amount Ws of rice. Wr−Ws=
0, that is, when the input amount Wr of the rice 16 reaches the appropriate amount Ws, the rice polishing section 3 stops driving and closes the opening 10. Then, the heating unit 74 is energized, the rice cooking pot 70 is heated, and rice cooking is started. Thereafter, the heating of the rice cooker 70 is controlled to a predetermined temperature by the control unit 80 based on the temperature detected by the temperature detector 75, and the rice 16 inside is cooked.

In the above embodiment, the scale 71 and numerical value 72 engraved on the side of the rice cooker 70 are used as a guide to adjust the rice cooker 7.
Although the explanation has been given by illustrating the case where water is poured into the rice cooker 70, it is also possible to put a rough amount of water into the rice cooker 70 by providing a measuring cup with an attachment that can measure the approximate amount of water corresponding to the amount of rice to be cooked.
