Description

[Detailed explanation of the idea] [Industrial field] The present invention relates to improvement of a rice milling machine.

[Conventional technology]

In order to eat rice deliciously, it is said that it is best to preserve it as brown rice and to polish it to an appropriate degree before eating, so to speak, to cook freshly ground rice. Rice milling machines for home use are commercially available.

Figure 3 shows a conventional rice milling machine, and in the figure, 1
1 is a case made of a steel plate or the like, and a brown rice storage section 3 for storing brown rice 2 is formed in the upper part of the case, and 4 is a hopper.

Below the lower opening 5 of the hopper 4 is a rice polishing device 6.
A rotating shaft 8 having a rice polishing roll 7 is installed horizontally in the rice polishing device 6, and this rotating shaft 8 is connected to an output shaft 13 of a motor 12 via a belt 9 and pulleys 10, 11. It is connected.

A bran drop cylinder 14 is formed below the rice polishing rolls 7 of the rice polishing device 6, and the end of the rice polishing device 6 on the rice polishing roll 7 side is opened as a rice drop opening 15.

Reference numeral 16 denotes a portioning degree adjustment mechanism, which is configured such that the presser lid 18 receives the pressing force of the spring 17 and closes the rice dropping opening 15.

Reference numeral 19 denotes an operation section provided approximately at the center of the front of the case, and as shown in FIG.
A measuring dial 21, a power switch 22, an indicator lamp 23, etc. are provided.

The polishing level dial 20 is used to set the degree of whitening, and the dials around it are "3 minutes", "5 minutes",
A scale 24 is formed to indicate the degree of portioning, such as "7-minute rice" and "white rice." By aligning the fineness dial 20 with a predetermined position on the scale 24, the shaft 25 directly connected to the fineness dial 20 is rotated.
(See Fig. 3) is rotated as appropriate to adjust the pressing force of the spring 17 of the portioning degree adjustment mechanism 16, and the strength with which the presser lid 18 closes the rice drop opening 15 is adjusted. . That is, the pressing force is the strongest when using "white rice" and the weakest when using "three-minute rice."

The measuring dial 21 is used to set the amount of rice to be milled, and around it are "1 go", "2 go", "3 go".
A scale 26 such as the following is formed. By setting the measuring dial 21 to a predetermined position on the scale 26, the timer circuit 27 shown in FIG. The motor 12 is configured to rotate for the same amount of time. That is, when milling rice at the same rate, the time required for milling is proportional to the amount of brown rice, so the amount of milled rice is set by setting the time for rotating the motor 12 using the timer circuit 27. be.

The polishing time, that is, the rotation time of the motor 12, varies slightly depending on the degree of rice milling.
The rice polishing time to obtain polished rice is set at 60 seconds, and this time becomes shorter as the degree of polishing decreases.

In FIG. 3, 28 is a container for receiving the polished rice 29, and 30 is a container for receiving the rice bran 31. In the illustrated example, these containers 28 and 30 are integrally formed, and are located below the case 1. It is provided in a storage section 32 opened in 2008 so that it can be inserted and removed freely. 33
is an upper lid, and the brown rice 2 is put into the brown rice storage section 3 by opening this upper lid 33. Further, 34 is a viewing window made of a transparent material such as glass.

In the rice milling machine configured as described above, the degree of rice milling is set using the milling dial 20, the amount of rice to be milled is set using the measuring dial 21, and the rice milling roll 7 is set using the motor 12. By rotating the rice cooker for a predetermined period of time, a predetermined amount of rice required for cooking can be polished at a predetermined rate.

[Problem that the invention attempts to solve]

By the way, in this type of rice milling machine, the amount of rice to be polished changes somewhat depending on the type and quality of brown rice (new rice or old rice) and the degree of fractionation, so the measuring dial 21 is adjusted to account for the change. Must be set. (For example, even if 3 cups of rice are required, the measuring dial 21 may vary depending on the type of brown rice, etc.)
It is necessary to set the scale position before and after the adjustment. ) However, in the rice milling machine with the above configuration, the measuring dial 21 is operated each time rice is milled, so it is very difficult and troublesome to move the dial to a predetermined position each time. This means that a certain amount of rice cannot be obtained. If there is too much or too little rice to be polished, delicious rice cannot be cooked due to the ratio of rice to water.

The present invention has been made with the above-mentioned considerations in mind, and its purpose is to provide a rice milling machine that can always mill a predetermined amount of rice without excess or deficiency.

[Means for solving problems]

In order to achieve the above object, the rice milling machine according to the present invention includes a rice milling device including a brown rice storage section, a rice milling roll for milling brown rice, and a motor for rotationally driving the rice milling roll, a polishing level dial, and the motor. It consists of a plurality of rice milling measurement keys set with different basic drive times, and an adjustment knob for setting the increase/decrease of the drive time of the motor according to the properties of brown rice. The time for driving the motor is set based on an input signal and an adjustment signal from the adjustment knob.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 1 shows an operating section 40 of a rice milling machine according to the present invention, and FIG. 2 shows a block diagram of the rice milling machine.

The operating section 40 shown in FIG. 1 and the conventional operating section 19 shown in FIG. A plurality of rice milling and measuring keys 41, 42, 43 set with different values, and an adjustment knob 44 for setting an increase/decrease in the drive time of the motor are provided. The difference is that the rice polishing amount can be set accordingly. Note that 45 is an index of the metering adjustment knob 44.

The rice polishing measuring keys 41, 42, and 43 are so-called touch-type keys, and are for setting 1 go, 2 go, and 3 go, respectively, and correspond to a predetermined number, although not shown in detail. Input signals Q ₁ , Q ₂ , Q ₃
(See Figure 2).

In this embodiment, the motor 12 is operated for 1 minute when the rice polishing and measuring key 41 for setting 1 cup is operated, and the rice polishing and measuring keys 42 and 3 for setting 2 cups are operated.
The motor 12 is configured to operate for 2 minutes and 3 minutes, respectively, when the rice polishing and measuring keys 43 for setting the rice polishing amount are operated.

46, 47, 48 are the rice milling measurement keys 41, 4
2 and 43, which are indicators made of, for example, light emitting diodes.

By rotating the metering adjustment knob 44, the value of a variable resistor (not shown) can be changed, and the time constant determined by this variable resistor and a capacitor (not shown) changes. This is the adjustment signal q
(See Figure 2).

In this embodiment, the upper and lower limits of the rice milling time adjustment range by the metering adjustment knob 44 are ±30 seconds. Therefore, the rice milling time when operating the rice polishing measurement key 41 for setting 1 go and the measurement adjustment knob 44 falls within the range of 30 seconds to 1 minute 30 seconds, and the rice polishing time for setting rice polishing and measuring key 42 for setting 2 go and 3 go In the case of the setting rice milling measurement key 43, the settings are from 1 minute 30 seconds to 2 minutes 30 seconds and 2, respectively.
Since it falls within the range of minutes 30 seconds to 3 minutes 30 seconds, you can set it within these ranges according to the characteristics of brown rice.

In Figure 2, 49 is an IC timer.
The IC timer 49 has rice milling measurement keys 41, 42,
Any one of the input signals Q ₁ , Q ₂ , Q ₃ from 43 and the adjustment signal q from the metering adjustment knob 44 are input, and the time for driving the motor 12 is set based on these two signals, and the brown rice storage Brown rice 2 in section 3 is polished by rice polishing rolls 7.

Note that the structure other than the above is the same as that described in the conventional example.

In the rice milling machine configured as described above, measurement is performed by operating any of the milled rice measuring keys 41, 42, 43, and on the other hand, the type and type of brown rice 2 stored in the brown rice storage section 3 are measured. A slight change in measurement (over- or under-measurement) depending on the quality and degree of portioning can be avoided with just one adjustment of the adjustment knob 44, which sets the time according to the nature of the brown rice. Just by operating the three rice milling measurement keys 41, 42, 43,
You can always measure the rice accurately and there will be no excess or deficiency in the amount of polished rice, so if you set the amount of water when cooking rice, you will always have delicious rice with the same softness. I can cook it. Therefore, even a dwarf can easily perform the series of tasks from rice polishing to cooking, and the rice can be cooked deliciously.

[Effect of idea]

As explained above, the rice milling machine according to the present invention is
A rice milling device including a brown rice storage section, a rice milling roll for milling brown rice, and a motor for rotationally driving the rice milling roll, a polishing level dial and a plurality of rice milling measurement keys set with different basic drive times of the motors; and an operating section having an adjustment knob for setting an increase or decrease in the drive time of the motor according to the properties of the brown rice, and the control unit controls the motor based on an input signal from the milled rice measurement key and an adjustment signal from the adjustment knob. Since the driving time is set, it is possible to always mill a predetermined amount of rice without excess or deficiency.

In addition, in order to obtain rice with the same graininess continuously over a long period of time by milling, according to the conventional technology, it was necessary to operate the measuring dial to set the polishing degree dial each time, which was very troublesome. According to the present invention, if you first set the measurement adjustment knob to a predetermined position, from then on, as long as the type of brown rice does not change, you only need to operate one milled rice measurement key. This has practical effects such as greatly simplifying seed manipulation.
