TECHNICAL FIELD The present invention relates to a rice bin with a rice mill.

[0002]

2. Description of the Related Art Conventionally, there is known a weighing rice bin which stores polished white rice and takes out a certain amount of polished rice via a weighing device at the time of cooking rice. However, white rice, which has been passed for a long time after the whitening, is oxidized and the taste deteriorates. Therefore, by purchasing brown rice and polishing it whenever necessary, it is possible not only to prevent a decrease in taste, but also to refine the rice to a desired degree. In this case, considering the recent housing situation, it is difficult to secure a place to install a rice mill in the kitchen other than a metering rice bin, and usually rice mills installed in agricultural cooperatives and supermarkets are used. Is the current situation.

In order to eliminate the trouble of bringing brown rice to the place where the rice mill is installed, a rice bin with a rice mill has been proposed, for example, as described in Japanese Utility Model Publication No. 57-36114.

[0004]

However, in the above-mentioned rice bin with a rice mill, a required amount of brown rice is measured and taken out, and the rice is milled as desired. Therefore, rice bran generated by milling brown rice is used. There is a drawback in that it is not possible to secure the required amount of white rice to be reduced and cooked. For example, when brown rice is milled into white rice, the weight is reduced by about 20 to 30%. In addition, when rice milling is required, the milling machine is driven to perform the milling, so it is necessary to wait until the milling is completed, and when the milling machine is activated, a certain operating sound (noise) is generated. There are also drawbacks such as housewives who are unfamiliar with sound feel uncomfortable.

[0005] The present invention has been made in view of such problems, and it is possible to always secure a required amount of white rice that has been whitened, and to have a housewife etc. whiten brown rice while not in the kitchen. The purpose is to provide a rice bin with a rice mill that can be used.

SUMMARY OF THE INVENTION The present invention relates to a brown rice storage hopper fixed to a machine frame, and a rice miller fixed to the machine frame with an input port facing the discharge port of the brown rice storage hopper and drivable via a motor. Milling machine, a rice storage hopper provided with an inlet at the outlet of the rice mill, and a rice milling hopper, which is integrally connected with the rice milling hopper, and an inlet opens at the outlet of the rice milling hopper to be rotatable on the machine frame. A weighing device supported on a shaft, a milling tray slidably provided on the machine frame below an outlet of the weighing device, and a control device for controlling a motor of the milling machine; The device is urged through an elastic body in a direction of restricting the rotation, and the brown rice storage hopper is provided with a first sensor for detecting that the stored amount of brown rice has fallen below a set amount. The frame contains less than the set amount in the rice polishing hopper. A second sensor is provided to detect that white rice has been stored, and when a predetermined amount or more of brown rice is thrown into the brown rice storage hopper, the rice milling machine is driven after a set time passes through the control device to whiten the brown rice. At the same time, when a set amount of white rice is stored in the rice storage tank, the operation of the rice mill is stopped via the control device, while the white rice stored in the rice storage hopper is discharged to the rice tray via the measuring device. In this case, the rice milling machine is driven after a lapse of a set time via the control device.

According to the present invention, when a set amount or more of brown rice is thrown into the brown rice storage hopper, the first sensor detects this, and after a lapse of a set time, the rice mill is driven to store the milled white rice. Supply to hopper. Then, when a set amount or more of white rice is stored in the milled rice storage hopper, the milled rice storage hopper rotates together with the measuring device against the urging force of the elastic body, and the second sensor detects this, and the milled rice milling machine detects this. To stop driving.

On the other hand, if the white rice stored in the milled rice storage hopper is taken out to the milled rice tray via the measuring device, the milled rice storage hopper and the measuring device are rotated by the urging force of the elastic body. After the detection and the elapse of the set time, the rice mill is driven again to start the whitening, and white rice is replenished by the reduced amount.

As a result, a required amount of white rice can be immediately taken out without waiting for the time to whiten brown rice. In addition, since the rice milling machine is driven after the set time has elapsed, the whitening can be completed while the housewife or the like is away from the kitchen or without knowing it. Never hear.

And a rice storage hopper 5 provided with an input port facing the discharge port of the polished rice, and integrally connected to the rice storage hopper 5, and the input port faces the discharge port of the rice storage hopper 5 and is rotatable with respect to the machine frame 2. A measuring device 6 which is supported on the machine frame, a milling tray 7 slidably disposed on the machine frame 2 below the measuring device 6, and a control device 8 for controlling the motor M (see FIG. 4). Have been.

A casing 9 is fixed to the machine frame 2 so as to cover the machine frame 2, the brown rice storage hopper 3, the rice mill 4, the milled rice storage hopper 5, and the scale 6.

The upper surface of the housing 9 is open, and a cover 91 is detachably provided so as to cover the opening. A selector 92 for adjusting the degree of milling is rotatably supported on the upper surface of the housing 9, and a power switch SW, an error warning lamp PL1, and a brown rice amount warning lamp PL are provided.
2 are provided (see FIG. 1). Further, a control device 8 and an alarm buzzer BZ are arranged on the back surface of the upper surface of the housing 9.

The brown rice storage hopper 3 is formed in a substantially truncated pyramid shape whose upper and lower surfaces are open, and a first sensor, for example, a micro switch S1 is provided on the back surface of one wall surface. The actuator of the microswitch S1 protrudes inside through a hole formed in one wall surface of the brown rice storage hopper 3, and an operation plate (not shown) rotatably supported above is disposed above the actuator. I have. For this reason, when brown rice of a set amount or more is stored in the brown rice storage hopper 3, the actuator is pressed via the operation plate, and the contact point of the microswitch S1 can be switched.

On one wall surface of the brown rice storage hopper 3,
A plastic sheet or a rubber sheet is laid over the operating plate.

Although not described in detail, the rice milling machine 4 is a conventionally known one. As will be described later, the urging force of an opening / closing door 42 rotatably provided facing a discharge port 4a of a main body case 41 is described below. By adjusting the value, white rice having a desired degree of whiteness can be obtained. At this time, the rice bran generated by whitening the brown rice is discharged through a bran net 43 and a chute (not shown) into a rice bran pocket 93 (see FIG. 1) that is freely attached to the housing 9.

Here, as shown in FIG. 3, the opening / closing door 42 has a rotating shaft 4 that is horizontal with respect to the main body case 41 of the rice milling machine 4.
It is rotatably supported around x and closes the outlet 4a. A support plate 44 is fixed to the main body case 41, and a cam 45 is attached to the support plate 44.
Are rotatably supported, and an arm 46 having a pin 461 that can abut on the cam 45 is rotatably supported. The tip of the arm 46 and the door 42
The elastic body 47 such as a coil spring
Are provided to urge the pin 461 into contact with the outer peripheral surface of the cam 45.

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 rotated. Can be rotated in the same direction. 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 to the white rice position. That is, when the selector 92 is rotated clockwise, in FIG.
Are rotated in the same direction, and the arm 46 is rotated clockwise with respect to the support plate 44 via a pin 461 that contacts the cam 45 by an increase in the distance. When the arm 46 rotates, the arm 46 is pulled above the door 42 by the urging force of the elastic body 47.

Therefore, in FIG.
Rotates in the counterclockwise direction of the rotation shaft 4x, and the elastic body 47
Is closed while pressing the outlet 4a of the main body case 41 by the urging force, the resistance when the refined white rice passes through the outlet 4a increases. As a result, the time during which the brown rice stays in the rice mill 4 increases, and the degree of milling can be increased.

Like the brown rice storage hopper 3, the milled rice storage hopper 5 is formed in a substantially truncated pyramid shape having open upper and lower surfaces, and its lower opening (discharge port) is integrally connected via a stay 51. Is inserted into the inlet of the measuring instrument 6. And, on the back of the rice storage hopper 5, a rod 5
2 is connected, and an elastic body 53 such as a coil spring is disposed between the tip of the rod 52 and the machine casing 2. Therefore, the milled rice storage hopper 5 is
Is biased so as to rotate in a counterclockwise direction of a rotating shaft 6b described later. A dog 54 is provided on one side of the rice storage hopper 5 so as to face a second sensor fixed to the machine frame 2, for example, a limit switch S2.
Is fixed, and when the set amount of white rice is stored in the milled rice storage hopper 5, the milled rice storage hopper 5 rotates clockwise of the rotating shaft 6b against the urging force of the elastic body 53. The contact of the limit switch S2 can be switched by pressing the actuator of the limit switch S2 via the dog 54.

The measuring device 6 includes a plurality of substantially cylindrical measuring hoppers 61 having different capacities opened upward and having the same rotating shaft 6.
A plurality of operation levers 62 each rotatably supported around a and having teeth (not shown) that mesh with teeth (not shown) formed on the outer peripheral surface of the weighing hopper 61.
Are rotatably supported around the same rotation shaft 6b, respectively, and by depressing each operation lever 62, each weighing hopper 61 is individually rotated by 180 degrees,
Alternatively, it is a conventionally known one in which a plurality of weighing hoppers 61 can be simultaneously rotated 180 degrees to take out a desired amount of white rice.

The measuring device 6 is rotatably supported by a mounting plate 21 fixed to the machine frame 2. In particular,
The rotation plate 6 of the operation lever 62 of the measuring instrument 6 is attached to the mounting plate 21.
b and a position corresponding to the rotation shaft 6a of the weighing hopper 61, a support hole 21a and an arc-shaped long hole 21b having a radius centered on the rotation shaft 6b of the operation lever 62 are formed, respectively. And arc-shaped slot 2
The rotation shaft 6b of the operation lever 62 and the rotation shaft 6a of the weighing hopper 61 are fitted into 1b, respectively. Therefore, the weighing device 6 can rotate together with the rice polishing hopper 5 around the rotation shaft 6 b of the operation lever 62 with respect to the mounting plate 21, that is, the machine frame 2. The shaft 6a moves along the arc-shaped long hole 21b.

As the control device 8, a central processing unit such as a CPU is used. 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. ,
Further, a motor M, an error warning lamp PL1, a brown rice amount warning lamp PL2, and a warning buzzer BZ are connected as output devices via a drive circuit D. Further, a timer T is connected to the control device 8.

Next, the operation of the rice bin 1 with the rice milling machine constructed as described above will be described.

First, after removing the lid 91 and putting the purchased brown rice into the brown rice storage hopper 3, the selector 92 is switched to a desired milling degree position and the power switch SW is turned on, so that the control device 8 operates. . Then, when a time set by the timer T, for example, 30 minutes has elapsed, the drive circuit D is operated, and the motor M is rotated via the drive circuit D.

When the motor M is driven to rotate, the rice mill 4 is driven via a belt-pulley, and the brown rice is milled to the milling degree set by the selector 92 and discharged from the outlet 4a. The white rice discharged from the discharge port 4a of the rice mill 4
It is gradually supplied to each weighing hopper 61 of the weighing device 6 and the rice storage hopper 5. At this time, since the white rice is stored in the milled rice storage hopper 5 and the scale 6, the milled rice storage hopper 5 and the scale 6 rotate in the clockwise direction of the rotating shaft 6 b against the urging force of the elastic body 53. I do. Then, when the set amount of white rice is stored in 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. 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 polishing machine 4.

Accordingly, the rice storage hopper 5 always stores a predetermined amount or more of white rice, and it is possible to take out a required amount of white rice without waiting for the time to whiten rice during cooking. In addition, since the rice mill 4 is driven after the set time has elapsed, it is possible to complete the milling of brown rice while the housewife or the like is away from the kitchen or without knowing it. I don't hear the sound.

By the way, in order to cook rice, the operating lever 62 of the measuring device 6 is depressed, and the measuring hopper 61 is rotated.
When the white rice stored in the weighing hopper 61 is taken out to the milling tray 7, the amount of white rice stored in the polished rice storage hopper 5 decreases, and the elastic body 53 rotates the polished rice storage hopper 5 and the measuring device 6 by the urging force. The shaft 6b is rotated counterclockwise. Accordingly, the dog 54 of the milled rice storage hopper 5 is separated from the actuator of the limit switch S2, and the contact returns to the original position. When a switching signal of the limit switch S2 is input to the control device 8,
After the lapse of the time set by the timer T, the control device 8
The motor M is rotated via the drive circuit D.

When the motor M is driven to rotate, the rice polishing machine 4 is driven to start whitening. And the rice storage hopper 5
When the brown rice for the white rice extracted from the rice is milled and the white rice is 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 its contact point. Stops the output to the motor M based on the switching signal of the limit switch S2 and stops the operation of the rice mill 4 as described above.

When the brown rice storage hopper 3 does not store more than the set amount of brown rice when the power switch SW is turned on, the contact of the micro switch S1 is not switched. Based on this, the brown rice warning lamp PL2 is turned on and the alarm buzzer BZ is sounded to notify the user.

When clogging occurs in the rice mill 4, a current exceeding a set amount flows to the motor, so that this overcurrent is detected to stop driving the motor M, and at the same time, an error warning lamp PL 1 Is turned on and an alarm buzzer BZ is sounded to notify the user.

In the above-described embodiment, the first
The case where the micro switch is used as the 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 and the limit switch. For example, the proximity switch, the photoelectric switch, the ultrasonic switch, etc. Various sensors may be employed.

[0034]

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 a lapse of a set time, the rice mill is driven to perform the whitening. Supply the milled white rice to the milled rice storage hopper. Then, when the set amount of white rice is stored in the milled rice storage hopper, the milled rice storage hopper rotates together with the measuring device against the urging force of the elastic body, and the second sensor detects this, and Stop driving. On the other hand, if the white rice stored in the milled rice storage hopper is taken out to the milled rice tray via the measuring device, the milled rice storage hopper and the measuring device are rotated by the urging force of the elastic body. After the set time has elapsed, the rice mill is driven again to start whitening, and white rice is replenished by the reduced amount. As a result,
The required amount of white rice can be immediately taken out without waiting for the time to whiten brown rice. Moreover, since the rice milling machine is driven after the set time has elapsed, the whitening can be completed while the housewife or the like is away from the kitchen or without knowing it. Never hear.
