[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a rice mill used mainly at home.
[0002]
[Prior art]
With the recent health boom and gourmet boom, more nutritious rice or more delicious rice has been actively studied. Under such circumstances, there is an increasing need for a rice mill for home use where rice can be cooked with freshly cooked rice.
[0003]
A conventional rice milling process of a rice mill will be described below.
[0004]
FIG. 6 shows the basic structure of a conventional rice mill. In FIG. 6, 1 is a hopper that feeds brown rice and sends it to the milled rice 12, 2 is a cap that presses the exit of the milled rice, 3 is a spring that presses the cap 2, and 4 is an adjuster that adjusts the pressure that holds the cap 2. 5 is a milled rice roll that pushes brown rice falling from the hopper section 1 toward the cap section 2, 6 is a milled net that separates the milled rice and rice bran, 7 is a motor section that rotates the milled rice roll 5, and 8 is the level of brown rice A sensor unit using a counter-type optical sensor that detects whether or not it remains, 9 is a control unit that receives a signal from the sensor unit 8 and controls the operation of the motor unit 7, and 10 is a control unit 9 that starts and stops rice milling. The switch part 11 for sending the signal of 11 is a straw container for storing the rice bran generated during the milling. Reference numeral 12 denotes a milled rice portion. The brown rice that has fallen from the hopper portion 1 is subjected to a force that is pushed out toward the cap portion 2 by the milled rice roll 5, and a force that is pushed back in the opposite direction by the cap portion 2. The brown rice is polished by rubbing each other in the milled net 6 by the force in the two directions. Since the milled net 2 has a slit, the rice bran that has been rubbed down falls into the straw container 11 from the slit.
[0005]
The operation of the rice milling process of the conventional rice mill configured as described above will be described below. First, when the switch is pressed in step 101 in the initial state (power-on state), the signal is sent to the control unit 9, and in step 102, the sensor unit 8 detects whether brown rice is present in the hopper unit 1. . If brown rice exists in the hopper part 1, it will transfer to step 103 and will start milling. When rice milling proceeds and the sensor unit 8 detects that brown rice is not present in step 104, the process proceeds to step 105 and the timer means works. The timer means is stopped in step 106 after the timer means has been operating for a certain period of time. If the sensor unit 8 detects that there is no brown rice in the hopper unit 1 in step 2, the process proceeds to step 107 and the timer unit stops operating in step 6 after the timer unit has been operating for a certain period of time. In response, rice milling stops.
[0006]
FIG. 7 shows the above operation.
[0007]
Next, the principle of rice polishing will be explained. The brown rice put in the hopper unit 101 passes through the sensor unit 108 and falls to the milled rice unit 112. A spiral groove is cut in the mandrel 105 of the rice milling unit 112, and when a rotational force is applied to the mandrel 105 by the motor unit 107, the brown rice that has fallen from the hopper unit 101 is sent out toward the cap unit 102. At this time, by the rotational force of the mandrel 105, the brown rices rub against each other and rice bran can be taken. The removed rice bran is dropped from the rice milling net 106 into the rice bran container 111 while the milled rice passes through the rice milling net 106, and the milled rice and rice bran are separated. The milled rice is pushed out from the cap portion 102 with a pressure higher than the spring pressure of the spring portion 103. Rice milling is performed in this way.
[0008]
[Problems to be solved by the invention]
However, the conventional configuration described above has the following problems. When the sensor unit detects the absence of rice and automatically stops after a certain period of time, the motor rotates the unpolished rice remaining in the milled net part that separates the milled rice and the rice bran without milling and pushing out from the cap. The brown rice is broken, and the next time it is polished, the broken rice comes out.
