BACKGROUND OF THE INVENTION
The present invention relates to a rice bin with a rice mill.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, weighed rice grains that store polished white rice and take out a certain amount of white rice through a measuring instrument when cooking rice are known. However, the white rice that has passed for a long time after milling is oxidized and the taste is lowered, and the preference for each is different in the degree of milling. Therefore, if brown rice is purchased and polished when necessary, not only can the deterioration of the taste be prevented, but it can also be refined to the degree of milling of their own preference. In this case, considering the recent housing situation, it is difficult to secure the installation location of the rice mill in the kitchen other than the metered rice, and usually the rice mill installed in agricultural cooperatives and supermarkets is used. Is the current situation.
[0003]
In order to eliminate the troublesomeness of bringing brown rice to the place where such a rice mill is installed, for example, as described in Japanese Utility Model Publication No. 57-36114, a rice mill with a rice mill has been proposed.
[0004]
[Problems to be solved by the invention]
However, in the above-mentioned rice bin with a rice milling machine, the necessary amount of brown rice is weighed and taken out, and it is whitened according to taste, so it is necessary to reduce the amount of rice bran generated by whitening the brown rice and try to cook rice There is a disadvantage that the amount of white rice cannot be secured. For example, when brown rice is refined into white rice, it is reduced by about 20-30%. In addition, when white rice is required, the rice milling machine drives the rice milling, so you have to wait until the milling is finished.When the rice milling machine is activated, a certain noise (noise) is generated and activated. There are also disadvantages such as housewives who are unfamiliar with the sound feel uncomfortable.
[0005]
The present invention has been made in view of such problems, and can always secure a necessary amount of polished white rice, and can polish brown rice while a housewife is not in the kitchen. A rice bowl with a machine is provided.
[0006]
[Means for Solving the Problems]
The present invention relates to a brown rice storage hopper fixed to a machine frame, a rice mill that is fixed to the machine frame with a charging port facing a discharge port of the brown rice storage hopper, and can be driven via a motor, and to a discharge port of a rice mill. A milled rice storage hopper provided with an inlet and a weighing machine connected to the rice storage hopper integrally, and pivotally supported on the machine frame with the inlet facing the outlet of the milled rice storage hopper. And a control device for controlling the motor of the rice milling machine, and the rice storage hopper and the meter are rotated via an elastic body. The brown rice storage hopper is energized in a direction that regulates movement, and the brown rice storage hopper is provided with a first sensor that detects that the stored amount of brown rice has fallen below the set amount. Check that more than enough white rice has been stored When the brown rice storage hopper is loaded with more than the set amount of brown rice, the rice milling machine is driven after the set time has passed through the control device to whiten the brown rice and the set amount in the polished rice storage tank When the white rice is stored, the drive of the rice milling machine is stopped through the control device. On the other hand, when the white rice stored in the rice storage hopper is discharged into the rice mill tray through the measuring device, the control device is used. The rice milling machine is driven after the set time has elapsed.
[0007]
According to the present invention, when a brown rice storage hopper with a set amount or more is put into the brown rice storage hopper, the first sensor detects this, and after the set time has elapsed, the milling machine is driven to supply the polished white rice to the milled rice storage hopper. To do. When the rice milling hopper stores more than a set amount of white rice, the second sensor detects this by rotating the rice milling hopper with the measuring device against the urging force of the elastic body. Stop driving.
[0008]
On the other hand, if the white rice stored in the milled rice storage hopper is taken out into the milled rice tray via the meter, the milled rice storage hopper and meter are rotated by the urging force of the elastic body, so the second sensor detects this, After the set time has elapsed, the milling machine is driven again to start milling, and white rice is replenished by the reduced amount.
[0009]
As a result, the necessary amount of white rice can be immediately taken out without waiting for the time to whiten the brown rice. Moreover, since the rice milling machine is driven after the set time has elapsed, the milling can be completed while the housewife is away from the kitchen or without knowing it. Never hear.

The milled rice storage hopper 5 provided in the above and a measuring device 6 integrally connected to the milled rice storage hopper 5 and pivotally supported with respect to the machine frame 2 with the input port facing the discharge port of the milled rice storage hopper 5. And a milled rice tray 7 slidably disposed on the machine frame 2 below the scale 6 and a control device 8 (see FIG. 4) for controlling the motor M.
[0013]
A housing 9 is fixed to the machine frame 2 so as to cover the machine frame 2, the brown rice storage hopper 3, the rice milling machine 4, the rice milling storage hopper 5, and the measuring device 6.
[0014]
In addition, the upper surface of the housing | casing 9 is opened, and the cover body 91 is attached detachably so that the opening part may be covered. Further, on the upper surface of the housing 9, a selector 92 for adjusting the degree of whitening is pivotally supported, and a power switch SW, an error warning lamp PL1, and a brown rice amount warning lamp PL2 are disposed ( (See FIG. 1). A control device 8 and an alarm buzzer BZ are disposed on the back surface of the upper surface of the housing 9.
[0015]
The brown rice storage hopper 3 is formed in a substantially truncated pyramid shape having an open upper surface and a lower surface, and a first sensor, for example, a microswitch S1 is provided on the back surface of one wall surface thereof. The actuator of the micro switch S1 protrudes inside through a hole formed in one wall surface of the brown rice storage hopper 3, and an operation plate (not shown) pivotally supported on the upper side is disposed. Yes. For this reason, when brown rice more than a set amount is stored in the brown rice storage hopper 3, the actuator is pressed through the operation plate, and the contact of the micro switch S1 can be switched.
[0016]
A plastic sheet or rubber sheet is laid on one wall surface of the brown rice storage hopper 3 so as to cover the operation plate.
[0017]
Although not described in detail, the rice milling machine 4 is conventionally known, and adjusts the biasing force of the open / close door 42 that is rotatably provided facing the discharge port 4a of the main body case 41 as will be described later. As a result, white rice having a desired degree of milling can be obtained. At this time, the rice bran generated by whitening the brown rice is discharged into a rice bran pocket 93 (see FIG. 1) that is detachably attached to the housing 9 through the bran net 43 and a chute (not shown).
[0018]
Here, as shown in FIG. 3, the open / close door 42 is pivotally supported around the horizontal rotation axis 4x with respect to the main body case 41 of the rice milling machine 4, and closes the discharge port 4a. A support plate 44 is fixed to the main body case 41. A cam 45 is rotatably supported on the support plate 44, and a pin 461 capable of contacting the cam 45 is provided upright. An arm 46 is pivotally supported. In addition, an elastic body 47 such as a coil spring is disposed between the tip of the arm 46 and the upper portion of the open / close door 42, and urges the pin 461 to contact the outer peripheral surface of the cam 45.
[0019]
The cam 45 is integrally connected to a selector 92 rotatably supported on the upper surface of the housing 9 via a shaft (not shown). By rotating the selector 92, the cam 45 is moved in the same direction. Can be rotated. The cam 45 is set so that the radius of rotation from the center of rotation gradually increases as the selector 92 is rotated clockwise from the brown rice position toward the white rice position. That is, when the selector 92 is rotated in the clockwise direction, in FIG. 3, the cam 45 rotates in the same direction, and the arm 46 is moved relative to the support plate 44 via the pin 461 that abuts the cam 45 by an increase in the distance. Rotate clockwise. When the arm 46 rotates, the upper side of the door 42 is pulled by the urging force of the elastic body 47.
[0020]
Therefore, in FIG. 2, the open / close door 42 is rotated in the counterclockwise direction of the rotation shaft 4x, and is closed while pressing the discharge port 4a of the main body case 41 by the urging force of the elastic body 47. Resistance when white rice passes through the discharge port 4a increases. As a result, the time during which brown rice stays in the rice mill 4 is increased, and the degree of whitening can be increased.
[0021]
Similar to the brown rice storage hopper 3, the milled rice storage hopper 5 is formed in a substantially truncated pyramid shape with its upper and lower surfaces open, and its lower surface opening (discharge port) is integrally connected via a stay 51. 6 is inserted into the slot. A rod 52 is connected to the rear surface of the milled rice storage hopper 5, and an elastic body 53 such as a coil spring is disposed between the tip of the rod 52 and the machine frame 2. Therefore, the milled rice storage hopper 5 is urged by the urging force of the elastic body 53 so as to rotate in the counterclockwise direction of the rotating shaft 6b described later. Further, a dog 54 is fixed to one side of the rice milling storage hopper 5 so as to face the second sensor fixed to the machine frame 2, for example, the limit switch S <b> 2. Is stored, when the milled rice storage hopper 5 rotates in the clockwise direction of the rotary shaft 6b against the urging force of the elastic body 53, the actuator of the limit switch S2 is pressed via the dog 54, and the contact Can be switched.
[0022]
The weighing instrument 6 is formed on the outer peripheral surface of the weighing hopper 61 while a plurality of substantially cylindrical weighing hoppers 61 having different capacities opened upward are rotatably supported around the same rotation shaft 6a. A plurality of operation levers 62 having teeth (not shown) meshing with teeth (not shown) are rotatably supported around the same rotation shaft 6b, and each operation lever 62 is pushed down. Each of the weighing hoppers 61 can be rotated 180 degrees individually, or a plurality of weighing hoppers 61 can be simultaneously rotated 180 degrees to take out a desired amount of white rice.
[0023]
The measuring instrument 6 is pivotally supported by a mounting plate 21 fixed to the machine casing 2 so as to be rotatable. Specifically, the mounting plate 21 has the support hole 21a and the rotation shaft 6b of the operation lever 62 at the rotation center at positions corresponding to the rotation shaft 6b of the operation lever 62 of the measuring instrument 6 and the rotation shaft 6a of the weighing hopper 61. The arc-shaped elongated holes 21b having the radii are formed, and the rotating shaft 6b of the operating lever 62 and the rotating shaft 6a of the weighing hopper 61 are respectively inserted into the supporting holes 21a and the arc-shaped elongated holes 21b. . Therefore, the measuring device 6 can be rotated together with the milled rice storage hopper 5 around the rotation axis 6b of the operation lever 62 with respect to the mounting plate 21, that is, the machine frame 2, at the time of rotation of the measuring hopper 61. The shaft 6a moves along the arc-shaped slot 21b.
[0024]
The control device 8 uses a central processing unit such as a CPU, and a power switch SW (see FIG. 1), a micro switch S1 as a first sensor, and a limit switch S2 as a second sensor are connected as input devices. A motor M, an error warning lamp PL1, a brown rice amount warning lamp PL2, and an alarm buzzer BZ are connected as output devices via a drive circuit D. Further, a timer T is connected to the control device 8.
[0025]
Next, the operation of the rice mill 1 with a rice mill configured as described above will be described.
[0026]
First, the lid body 91 is removed, the purchased brown rice is put into the brown rice storage hopper 3, and then the selector 92 is switched to the desired whiteness position and the power switch SW is turned on, whereby the control device 8 is activated. When the time set by the timer T, for example, 30 minutes elapses, the drive circuit D is operated, and the motor M is driven to rotate through the drive circuit D.
[0027]
When the motor M is driven to rotate, the rice mill 4 is driven via the belt-pulley, and the brown rice is whitened to the degree of whitening set by the selector 92 and discharged from the discharge port 4a. The white rice discharged from the discharge port 4 a of the rice mill 4 is gradually supplied to each weighing hopper 61 and the milled rice storage hopper 5 of the measuring device 6. At this time, the white rice is stored in the milled rice storage hopper 5 and the meter 6 so that the milled rice storage hopper 5 and the meter 6 rotate in the clockwise direction of the rotating shaft 6b against the urging force of the elastic body 53. To do. When the amount of white rice set in the milled rice storage hopper 5 is stored, the dog 54 of the milled rice storage hopper 5 presses the actuator of the limit switch S2 to switch the contact. When the switching signal of the limit switch S2 is input to the control device 8, the control device 8 stops the output to the drive circuit D, that is, the motor M, and stops the drive of the rice milling machine 4.
[0028]
Therefore, the polished rice storage hopper 5 always stores more than a set amount of white rice, and the required amount of white rice can be taken out without waiting for the time for whitening during rice cooking. In addition, since the rice mill 4 is driven after the set time has elapsed, the milling of the brown rice can be completed while the housewife is away from the kitchen or without knowing it. I don't hear sound.
[0029]
By the way, in order to cook rice, if the operation lever 62 of the measuring device 6 is pushed down, the measuring hopper 61 is rotated, and the white rice stored in the measuring hopper 61 is taken out into the milled rice tray 7, the white rice stored in the polished rice storage hopper 5 is obtained. Accordingly, the elastic body 53 rotates the milled rice storage hopper 5 and the meter 6 in the counterclockwise direction of the rotary shaft 6b by the biasing force. Therefore, the dog 54 of the milled rice storage hopper 5 is detached from the actuator of the limit switch S2, and the contact is returned to the original position. When the limit switch S2 switching signal is input to the control device 8, the control device 8 rotates the motor M via the drive circuit D after the time set by the timer T has elapsed.
[0030]
When the motor M is driven to rotate, the rice mill 4 is driven and the whitening is started. And if the brown rice for white rice taken out from the milled rice storage hopper 5 is refined and supplied to the milled rice storage hopper 5, the dog 54 of the milled rice storage hopper 5 presses the actuator of the limit switch S2 to switch the contact point. Therefore, as described above, the control device 8 stops the output to the motor M based on the switching signal of the limit switch S2, and stops the drive of the rice milling machine 4.
[0031]
In addition, when the brown rice storage hopper 3 has not stored more than a set amount of brown rice when the power switch SW is turned on, the contact point of the micro switch S1 is not switched, so based on the detection result of the micro switch S1, The brown rice amount warning lamp PL2 is turned on and the alarm buzzer BZ is sounded to notify the user.
[0032]
In addition, when clogging occurs in the rice milling machine 4, a current exceeding the set amount flows to the motor, so this overcurrent is detected to stop the driving of the motor M and at the same time, the error warning lamp PL1 is turned on. The alarm buzzer BZ is sounded to notify the user.
[0033]
In the above-described embodiment, the case where the micro switch is used as the first sensor and the limit switch is used as the second sensor has been described. However, the present invention is not limited to the micro switch or the limit switch. Various sensors such as a proximity switch, a photoelectric switch, and an ultrasonic switch may be employed.
[0034]
【The invention's effect】
As described above, according to the present invention, when brown rice of a set amount or more is put into the brown rice storage hopper, the first sensor detects this, and after the set time has elapsed, the rice mill is driven to turn the polished white rice into polished rice. Supply to storage hopper. When a set amount of white rice is stored in the rice mill storage hopper, the second sensor detects this by rotating the rice mill storage hopper together with the meter against the urging force of the elastic body. Stop driving. On the other hand, if the white rice stored in the milled rice storage hopper is taken out into the milled rice tray via the meter, the milled rice storage hopper and the meter are rotated by the urging force of the elastic body, so the second sensor detects this, After the set time has elapsed, the milling machine is driven again to start milling, and white rice is replenished by the reduced amount. As a result, the necessary amount of white rice can be immediately taken out without waiting for the time to whiten the brown rice. Moreover, since the rice milling machine is driven after the set time has elapsed, the milling can be completed while the housewife is away from the kitchen or without knowing it. Never hear.
