Description

Table cleaning machine

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice polisher for refining brown rice, and in particular, to a tabletop rice mill of a small size and light weight that enables the bran to be easily separated when the bran of the brown rice is chopped, and to lower the frictional heat of the rice during the rice polishing.

Conventionally, in the rice milling machine, as described in Japanese Utility Model Publication No. Hei 5-36500 by the same applicant, a rice milling shaft and a rice milling screen (rice milling roll) : Rice milling roller is used to scrape off a layer of brown rice (shelled rice). In this case, if the bran is not separated well, that is, if the bran separation is poor, the oxidation rate of the rice is increased, resulting in deterioration of the taste of rice and aging of the rice. This tendency is particularly true of some so-called rice polished (eg 50% milled state or 50% milled degree of rice), leaving some of the brown rice nutrients, the stratum corneum. In the state of the 30% crushed state is called 7 unrefined rice or 30% whitening), if the bran is separated poorly, the oxidation rate of the rice is faster, and the taste of rice is markedly reduced.

Therefore, in a commercial rice mill, the bran cut by a vacuum machine is forcibly sucked, or the bran is blown by a wind by a wind fan or the like to separate the bran from the rice. However, in this case, it is necessary to arrange a suction machine, a blowing fan, etc. in the vicinity of the container container, so that the apparatus becomes complicated and large, and expensive, and therefore, it is not employed in domestic rice mills.

Therefore, in the conventional domestic rice mill, bran was separated from rice by naturally dropping the bran cut by the net shaft, the netting net, and the like.

In addition, when the rice is polished by the net shaft, the net, etc., the frictional heat is generated by the friction between the brown rice and the net shaft, the net and the like, the temperature of the rice after the rice is high. If the temperature of the rice increases, the rice taste is reduced by the deterioration of the quality of the rice. For commercial rice mills, for example, the rice is divided into three stages so that the rice is gradually polished to prevent the rice temperature from rising. However, in the domestic rice milling machine, since it is polished once at once, the temperature of rice by frictional heat especially becomes high.

In addition, since the bran has an oil component, the bran crushed at the time of polishing is likely to adhere to the net shaft and the netting net. In particular, when the temperature due to the frictional heat increases, the bran is easily attached to the net shaft and the netting net when the temperature decreases after the netting. Therefore, it is necessary to disassemble the rice polisher regularly, clean the rice polisher and the netting net, and remove the bran attached to the rice polisher and the netting net, and thus maintenance is cumbersome.

In addition, since a conventional rice mill is composed of a rice hopper portion (hopper portion), a rice mill shaft, a rice net, etc., the size of the rice mill as a whole becomes large, and in kitchens, it is large as a place to place rice mills. Space was needed. Moreover, since the domestic rice grinder is mainly comprised of steel materials, the weight of the whole became heavy, and it was unsuitable for tabletop use. That is, the average weight of the current domestic rice mill is about 10 kg.

In addition, in the case of polishing with a domestic rice polisher, the whiteness can be adjusted, but the rice whiteness cannot be confirmed until the rice is discharged in fact. For this reason, it was difficult to adjust the whiteness according to the difference in the type of brown rice and the amount of water contained, and cracks and crumbs of rice were generated by the process of whiteness.

As described above, in the conventional domestic rice scouring machine, measures such as poor bran separation, temperature rise of rice due to the generation of frictional heat, troublesome maintenance due to blockage of bran or rice, enlargement, and difficulty in confirming whiteness are considered. As a result, problems such as deterioration of the rice taste of rice after milling were caused.

SUMMARY OF THE INVENTION An object of the present invention is to provide a tabletop rice cleaning machine which solves the problems of the conventional domestic rice cleaning machine.

In order to achieve the above object, the table-top polisher according to the present invention is fitted with a motor, a tip of a drive shaft that rotates in accordance with the rotation of the motor, and a net blade that rotates together with the drive shaft, and the drive shaft is concentric with the drive shaft. A circular bottom portion having a cylindrical circumferential portion and an opening through which the drive shaft passes, a circular basket accommodating the net wing, a circular bottom portion having a cylindrical circumferential portion concentric with the drive shaft, and an opening through the drive shaft. And a body box for accommodating the net basket and the net wing and the net basket and the bran box, respectively, for freely receiving and removing the net basket, and fixedly accommodating the motor. The side circumference of the basket is comprised of a metal net, and at the time of rice cleaning puts brown rice in the rice basket mentioned above By rotating the mower, the brown rice is agitated by the rotation of the net blade, and the brown rice is chaffed by the centrifugal force on the mesh of the net of the net basket, and the chaff is cut out from the net by the centrifugal force. To the side to fall into the box.

In the table cleaning machine configured as described above, the rice is stirred by the rotation of the net blades, and the rice is rubbed by the centrifugal force of the net of the net basket by the centrifugal force of the rice. It is configured to be deposited. In this way, bran separation is good because the bran is blown from the mesh of the iron net. Therefore, the bran is hardly attached to the net of the net basket, and even if it is attached, the bran should be taken out and cleaned, and it is very easy. Similarly, the bran in the bran box can be easily removed by cleaning the bran box. Moreover, since the wind is generated by the net blade when the rice is stirred by the rotation of the net blade, the temperature rise of the rice is prevented and the taste of the rice is reduced. You can prevent it. Moreover, since whiteness can be grasped | ascertained easily from the window of a cover, adjustment of whiteness is also easy. In addition, since there is no net rice or white rice container, the rice mill can be downsized and light in weight, so it can be placed in a narrow place in the kitchen and can be made into a tabletop type.

Moreover, according to the table-top polisher of this invention, the rotation speed of a netting blade is set in the range of 1500-3000 rpm, and since rotation speed is too fast, rice does not splash and hits a lid, but does not become a net rice or rice. Cracking or entrapment, and too slow, the rice is simply agitated and does not bump into the metal net to prevent it from being polished, so that proper milling is performed.

Moreover, according to the table-top polisher of this invention, when the mesh shape of the metal mesh of the side peripheral part of a rice basket is rhombic, the length of the short nose (short side) direction is the range of 2.2-3.0 mm, and the long nose (long side) direction The length of is in the range of 3.0 to 4.6 mm, and in the case of a quadrilateral, the length of one side in the longitudinal and transverse directions is all in the range of 2.0 to 3,0 mm, and in the case of a circular shape, the diameter is in the range of 2.0 to 3.0 mm. While rice is prevented from coming out from the outside from the metal mesh of the side part of a rice basket, appropriate rice-making is performed.

Moreover, according to the table-top polisher of this invention, although the angle with respect to the circular bottom part of the net basket of a netting blade exists in the range of 15-35 degree, brown rice is agitated suitably and it rubs against the metal mesh of the side peripheral part of a net basket by this. .

Moreover, according to the table-top polisher of this invention, since the cover which has the transparent window which covers the upper opening part of a rice basket is provided, the whiteness of brown rice can be grasped easily through this window, and adjustment of whiteness is easy.

Moreover, according to the tabletop cleaning machine of this invention, it has a control circuit accommodated in a main body case and controls a motor, The control circuit has a rectifier and a digital timer which rectify AC power, and set time as a digital timer. Only the rectifier current is supplied to the motor to rotate the netting blades, and thus, by adjusting the digital timer, rice of proper whiteness can be obtained.

Further, a phase control circuit connected in series to the rectifier may be further provided so as to control the energization phase of the current supplied to the motor in accordance with the amount of fine brown rice (ie, the load of the motor). That is, the more the net weight is, the larger the conduction phase angle is, so that the supply current to the motor is increased, and the number of revolutions of the net blade is stabilized to a predetermined value (for example, in the range of 2000 to 2200 rpm) regardless of the net amount. You may also do it. Thereby, the rotation speed of the netting blade does not become too fast when the quantity of rice is small, and the rotation speed does not become slow when the quantity of rice is high.

7 shows an example of the configuration of a control circuit in the control circuit box 8. The two cords 27a and 27b of the power cord 27 are connected with a capacitor 52 for removing noise, and also a digital timer 50, a phase control circuit 54 and four diodes. The full-wave rectifier 60 which consists of SR1-SR4 is connected. The motor 10 is connected to the output of the full-wave rectifier 60. A safety switch 56 is connected to the serial circuit of the digital timer 50, the phase control circuit 54, and the full-wave rectifier 60. For example, the safety switch 56 is linked to a knob 65 provided on the upper surface of the upper end portion 30a of the box-box accommodating case 30, and the cover 3 is covered so that the box box accommodating case 30 is provided. When placed on the upper surface of the upper end portion 30a of the knob 65, the knob 65 is pressed so that, in conjunction with it, the switch 56 is turned on, and when the lid is opened, the knob 65 turns the return switch 56 off. off). In this way, when the cover 3 is open, the motor 10 is rotated to prevent the net wing assembly 9 from rotating.

Next, the function of each button of the operation panel 7 will be described. When the net time (minutes) is set by the net time setting button 72, a signal indicating the net time is given to the digital timer 50 so that an on time equal to the net time set is set, and the display unit 74 is given. The set time is displayed. In addition, when the net time (minutes) is set by the net time setting button 72, the phase control circuit 54 sets the motor phase angle between the motor 10 at a predetermined speed (preferably between 1500 and 3000 rpm). Speed) so as to rotate at a predetermined phase angle. And, if the rotation speed of the motor 10 is too fast, the rice splashes and does not hit the iron net without hitting the lid, and the rice is not polished, and if the rice is cracked or wrapped, and the rice is too slow, the rice is just stirred. Since it does not hit the net and is not polished, it is set in the above range. Therefore, after that, when the netting button 70 is pressed and a signal indicating the netting is given to the digital timer 50, the timer 50 is turned on and the electric current set by the phase control circuit 54 at the predetermined energizing phase angle. Current is supplied to the motor 10 through the timer 50, the switch 56, and the rectifier 60 to rotate the motor 10 at the predetermined speed. Thereafter, when the netting time set by the netting time setting button 72 has elapsed, the timer 50 is turned off, the power supply to the motor 10 is stopped and the motor 10 is stopped. When the netting button 70 is pressed again during netting, the signal from the button 70 is given to the digital timer 50 to turn off the digital timer 50, stops the motor 10, and stops netting. do.

The rice amount setting button 73 is the amount of brown rice (i.e., rice amount) when the rice is polished with white rice (rice of 100% whiteness), for example, 1 hop (180 m1), 2 hops (360 m1), Any one of three hops (540m1), four hops (720m1), and the like is set, and a signal indicating the set value is given to the display unit 74 to display the set net amount. In addition, a signal indicating the set net amount is given to the digital timer 50 and the phase control circuit 54 to set the on time of the timer 50 and the conduction phase angle of the phase control circuit 54 as follows. That is, to control the conduction phase of the current supplied to the motor according to the amount of rice to be polished (that is, the load of the motor), the greater the netting amount, the greater the conduction phase angle to increase the supply current to the motor The number of revolutions of the netting blade is stably set to a predetermined value (for example, in the range of 2000 to 2200 rpm) regardless of the net amount and without being affected. That is, for example, in the case that the set net amount is 1 hop, 2 hop, 3 hop, 4 hop, as shown in the following table, the energization phase angles are 60%, 70%, 80%, 100% (maximum), respectively. Further, the netting time (on time of the timer 50) is set to be 1 minute, 1.5 minutes, 2 minutes, and 2.5 minutes, respectively. By setting in this way, the rotation speed of a netting blade can be made stably in the range of 2000-2200 rpm irrespective of a net amount, and stable netting can be performed. Therefore, after that, when the netting button 70 is pressed and a signal indicating the netting is given to the digital timer 50, the timer 50 turns on only the time corresponding to the set netting amount and the phase control circuit 54 The current of the conduction phase angle corresponding to the set net amount of is given to the motor 10 to rotate the motor 10 to generate white rice. Then, when the netting button 70 is pressed again during the netting, the signal from the button 70 is given to the digital timer 50 to turn off the digital timer 50 to stop the motor 10 to stop the netting.

When the refining button 78 is pressed, a signal indicative of netting is given to the digital timer 50 and the phase control circuit 54 while being pressed to give the conduction phase angle of the phase control circuit 54, for example, to the predetermined value. At the same time as setting the phase angle of, the timer 50 is turned on while the motor 10 is rotated. If you release the rearrangement button 78, the signal indicative of netting is stopped and the motor 10 stops rotating. Therefore, the desired whiteness can be obtained by pressing the rearrangement button 78 while looking at the whiteness of brown rice through the window 2 after polishing.

In this way, when the desired whiteness is polished, the netting time setting button 72 is used to set the netting time (minutes) to an appropriate value. When the rice is polished with brown rice, the net amount is set by the net amount setting button 73 and refined. In any case, since the rice milling can be stopped by pressing the rice milling button 70 during rice milling, the rice milling is stopped by pressing the rice milling button 70 at an appropriate time while looking at the whiteness of brown rice through the window 2 during rice milling. You can get the desired degree of whiteness.

In the present embodiment, both the net time setting button 72 and the net amount setting button 73 are provided, but only one of them is installed to rotate the motor 10 according to either the net time or the net amount. You can make the rice you want.

For example, when only the net time setting button 72 is provided, the phase control circuit may not be provided and the net wing may be rotated within a range of 1200 to 3000 rpm.

In addition, as shown in FIG. 8, when both the net time setting button 72 and the net amount setting button 73 are provided, the phase control circuit may not be provided. In that case, for example, in the case of the set net amount of 1 hop, 2 hop, 3 hop, 4 hop, the on time of the timer 50 is set to be 1 minute, 2 minutes, 3 minutes, and 4 minutes, respectively. As a result, the number of revolutions of the netting blade is rotated at, for example, 2500 rpm, 2350 rpm, 2100 rpm, and 1850 rpm.

Next, the operation of the table polisher 100 thus constructed will be described with reference to FIG. First, as shown in FIG. 8, the box box 6 is accommodated in the box box accommodating case 30, and the net basket 5 is also accommodated in the box box 6 so that the net wing assembly 9 is formed in a hexagonal shaft assembly ( In the state fitted to 16), the desired amount of brown rice 90 is placed in the net basket 5 and the lid 3 is closed. Subsequently, the power plug 28 is inserted into an outlet and the netting time is set by the netting time setting button 972, or the netting amount is set by the netting amount setting button 73. When the netting button 79 is pressed, the motor 10 rotates and the netting wing assembly 9 is rotated. Then, the brown rice 90 is agitated by the rotation of the netting blade 9a, and the brown rice is rubbed by the centrifugal force by the mesh of the metal net 5a of the net basket 5 and then flakes off. In addition, the chaff (9) that has been cut off is blown outward from the mesh by centrifugal force to fall into the chaff box (6). At this time, since the whiteness state of brown rice can be seen through the transparent window 2 of the lid 3, the rice milling can be stopped by pressing the rice milling button 70 at an appropriate point in time, thereby obtaining desired whiteness. If it is determined that the rice is needed to raise the whiteness again after such a rice polishing, the rice refinement button 78 is refined by pressing the rice refinement button 78, or again by the rice milling time setting button 72 or the net rice amount setting button 73. It can be rearranged to the desired whiteness. In this way, bran is easily separated from brown rice, and rice of desired whiteness can be obtained.

After the polishing, the lid 3 is removed, and the netting wing assembly 9 is removed from the hexagonal shaft assembly 16 again, and the rice basket 5 is taken out to remove rice after rice in the rice basket 5. At this time, the rice in the net basket (5) may be poured into the state as it is to wash the rice. Moreover, the bran box 6 is taken out and the bran in it is discarded.

As described above, according to the rice cleaning machine of the present invention, bran is separated from the mesh of the net 5a by centrifugal force of rice. Therefore, the bran is deposited in the bran box 6, so that the iron net 5a can be easily cleaned, and the bran can be easily discarded from the bran box 6. In addition, since the wind is generated by the netting blades 9a when the rice is stirred by the rotation of the netting blades 9a, the temperature rise of the rice is prevented and the deterioration of the taste of the rice can be prevented. In addition, since there is no net rice or white barrel like a conventional rice mill, rice is not worried about clogging and maintenance is very easy. That is, the bran is hardly attached to the metal mesh 5a of the net basket 5, and even if it is attached, it is enough to take out and clean the net basket 5, and it is very easy. Similarly, the bran in the bran box 6 can be easily removed by removing the bran box 6. Moreover, since the whiteness can be easily grasped | ascertained through the window 2 of the lid | cover 3, adjustment of the whiteness is also easy. For this reason, it is easy to adjust the whiteness according to the difference of the type of brown rice and the amount of water contained, and it is possible to prevent the cracking and the sagging of the rice due to over-adjustment of the whiteness. In addition, since there is no net rice or white rice container, the rice mill can be downsized and can be about 3 kg in weight, so it can be placed in a narrow place in the kitchen and can be made into a tabletop type. In addition, the rice cleaning machine of the present invention is capable of not only rice but also rice grains such as barley and crude.

As described above, according to the table-top polisher of the present invention, the rice is agitated by the rotation of the net blades, the rice is rubbed by the mesh of the net of the rice basket by the centrifugal force of the rice, and the bran is shaved, and the bran is cut out again from the mesh by the centrifugal force. It is designed to be blown and deposited in the box. In this way, the bran is blown away from the mesh of the iron net so that the bran is separated. Therefore, the bran is hardly attached to the net of the net basket, and even if it is attached, the bran should be taken out and cleaned, and it is very easy. Likewise, the bran in the bran box can be easily cleaned by removing the bran box. In addition, when the rice is stirred by the rotation of the net blades, wind is generated by the net blades, so that the temperature rise of the rice is prevented, and the deterioration of the taste of the rice can be prevented. In addition, since whiteness can be easily grasped | ascertained through the window of a cover, adjustment of whiteness is also easy. In addition, since there is no net rice or white rice container, the rice mill can be downsized and light in weight, so that the rice mill can be placed in a narrow place in the kitchen and can be made into a tabletop type.
