Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a rice milling machine, particularly to a rice milling operation control device for a recirculating rice milling machine.

Conventional technology In recent years, the nutritional effects of eating brown rice and rice bran have been widely recognized, and rice milling machines have become commonplace in households. It has become commonplace to immediately process and eat the rice bran that is obtained from time to time.

A simple rice milling machine for general household use has been proposed that uses a timer switch to measure the amount of polished rice. One example is a rice mill that has a timer switch connected in series with the rice mill's motor, and a scale plate that has a weight scale or capacity scale that converts the milling time into the amount of rice milled. Publication No. 51-42026).

The problem that the invention aims to solve is that even with the same rice milling equipment, the time required to mill a certain amount of rice varies depending on the type of brown rice, and furthermore, the rice quality, such as the grain size and moisture content of the two grains of origin, and the setting. It also varies depending on conditions such as the degree of rice polishing. Therefore, even if the amount of rice to be milled was simply set using a timer switch, it was often not possible to mill the desired amount of rice.

The present invention solves these problems by providing a rice milling operation control device for a rice milling machine that can accurately obtain the desired amount of milled rice under various conditions including the type of brown rice used. The purpose is to provide.

Means for Solving the Problems The rice milling operation control device of the rice milling machine of the present invention includes a memory that stores the rice milling time per unit amount corresponding to conditions such as the type of brown rice, and a memory that stores the rice milling time per unit amount. An input means for storing, a rice milling amount setting means for setting a desired rice milling amount and inputting it into the memory, and a rice milling time based on the desired rice milling amount input by the rice milling amount setting means and the contents stored in the memory. It is equipped with a microcomputer that calculates and generates a control signal, and a motor drive device that is controlled by the control signal from the microcomputer.

With this configuration, when the brown rice used is changed, the milling time per unit amount of brown rice is stored in the memory in advance by the input means, so the microcomputer can store the milled rice amount set by the setting means and the memory. The rice milling time is calculated based on the content and the operation of the motor drive device is controlled.

Embodiment Hereinafter, the configuration of a rice milling operation control device of a rice milling machine in an embodiment of the present invention will be explained with reference to FIG.

As shown in the figure, this embodiment includes a microcomputer 1 that plays the central role of control, a setting switch 2 for setting the desired amount of rice milled, the type of brown rice, its production area, the size of each grain, moisture content, etc. A set switch 3 for inputting rice milling time according to conditions such as differences in rice quality, a start switch 4 for inputting the start of rice milling operation, and for displaying the input results from these switches 2゜3.4. A display element 5.6.7 consisting of a light emitting diode,
A rice milling motor drive device 8 controlled by a microcomputer 1, and a memory 9 that stores rice milling times input according to conditions such as the type of brown rice, its production area, the size of a single grain, and the difference in rice quality such as moisture content. and a changeover switch 10 for selecting either the memory mode or the normal rice milling operation mode.

The arrangement of the switches 2 to 4 and the display elements 5 to 8 is as shown in FIG. 3.

In the figure, the switch 2 consists of switches 21 to 25 corresponding to 1 to 5 times the unit quantity, respectively, and the display element 5 consists of display elements 51 to 55 corresponding thereto.

□In this embodiment, the procedure for setting the rice polishing time will be explained using the flowchart shown in FIG.

First, a power switch (not shown) is turned on, and the selector switch 10 is set to the rice milling time setting side to set the rice milling degree. When the time setting side input of the changeover switch 10 is input, the microcomputer 1 flashes the display element 6 to indicate that it is waiting for an input from the set switch 3. In other words, it is displayed that the mode is for storing the milling time per unit amount in the memory 9. Next, when the unit measuring cup is prepared to receive the milled rice and the set switch 3 is pressed, the microcomputer 1 sends a control signal to the motor drive device 8 to energize the motor of the rice milling machine and start milling the rice. Count the time base pulses and start timer addition. set switch 3
If you keep pressing , the rice will be polished and the time will be counted.

When the milled rice fills the unit measuring cup and reaches the specified amount, release the set switch 3, and the microcomputer 1
The motor of the rice milling machine (not shown) is driven by the motor drive device 8.
At the same time, the timer addition operation is stopped.

Then, when the changeover switch 4 is set to the lock side, the microcomputer 1 stores the timer addition value in the memory 9 and changes the set switch display element 6 from a blinking state to a lighting state, completing the setting of the unit measurement time. Show that. In other words, it is displayed that the normal rice milling operation mode has been returned.

As described above, the memory 9
After memorizing the milling time per unit amount, set the desired rice milling amount with switch 2 and mill the rice.
The microcomputer 1 calculates the rice milling time for the set rice milling amount based on the rice milling time per unit amount stored in the memory 9, and controls the operation of the motor drive device 8 to perform rice milling.

In other words, the user stores the milling time per unit amount in the memory 9 in advance according to the brown rice that he or she wants to mill (just by setting the desired rice milling degree and milling amount and pressing the start switch 4, The motor operates, a load is applied to the milling chamber according to the predetermined rice milling degree, and the brown rice is agitated and polished, and the time corresponding to the set rice milling amount is set based on the unit amount milling time stored in the memory 9. When it reaches this point, the motor automatically stops and rice milling ends.

Therefore, an accurate amount of polished rice can be obtained without being affected by the type of rice or the degree of polishing.

Note that if the same procedure is used to set the unit amount milling time for each portion in the memory 9 in advance, even if the portion is changed, the microcomputer 1 will perform calculation processing based on the contents stored in the memory 9. Then set the rice polishing time and let the rice mill.

Furthermore, if the arithmetic circuit of the microcomputer 1 is equipped with a calculation means for calculating each rice milling time from the milling rate for each minute, for example, by simply storing only the milling time for a unit amount of polished rice, each milling time for each minute can be calculated. The rice milling time for the rice milling amount is calculated and controlled, making it more convenient.

Effects of the Invention According to the rice milling operation control device of the rice milling machine of the present invention, since the rice milling time per unit amount is stored in advance in the memory according to conditions such as the type of brown rice, the rice milling amount is set immediately. The microcomputer can calculate the milling time and control the motor drive to obtain the correct amount of milled rice.
