Description

[0001]
BACKGROUND OF THE INVENTION
[0001] The present invention relates to a rice sharpener mainly used at home.
[0002]
[Prior art]
An example of a rice-shearing machine that performs rice-shearing without using water is described in Japanese Patent Application No. 2000-042535. This type of rice sharpener is composed of a rice hopper, a rice-cutting portion, a straw suction portion, a rice receiver, an operation portion, and a control device. The rice hopper has a weighing function at its lower part, and the weighed rice is further discharged to the lower part of the rice edge and is removed by rotating the blade member of the rotating body arranged in the rice edge. The rice that has been subjected to dredging and removed is discharged to the rice tray through a rice milling opening provided in the rice splinter. Further, the soot removed at that time is sucked by the soot sucking portion and stored in a container such as a paper pack of a vacuum cleaner.
[0003]
The operation unit is provided with a display unit in addition to a switch such as a power switch and a rice milling amount setting switch, and the control device controls various loads according to the contents set by the operation unit. For example, a series of operations such as metering, removal, and rice discharge are repeated so as to reach the total number set by the rice milling amount setting switch.
[0004]
[Problems to be solved by the invention]
However, in the above configuration, the cocoon removed is stored in a container such as a paper pack or a cloth bag. However, when the maximum capacity of the container is reached, the function of sucking the cocoon is not achieved. Furthermore, if the container overflows, the sucked soot accumulates in various places other than the container, which may cause troubles such as clogging of pipes. Therefore, it is necessary to perform maintenance before the culm reaches its maximum capacity, but in order to grasp the timing, the container for storing the culm is made of an opaque material such as a paper pack or cloth bag. There was annoyance that I had to remove and check the contents.
[0005]
Some rice sharpeners use consumable parts. For example, a blade member that is rotationally driven in a rice-toe portion wears away as the use progresses, and the debridement function deteriorates. Therefore, it has been necessary to replace the blade member when it has exceeded its useful life. However, there is no means for notifying the timing, and there is no way for the user to judge the degree of wear by removing the blade member from the device and checking the degree of wear directly.
[0006]
Some rice sharpeners can set the degree of rice sharpening, for example, “weak” or “strong”. If the driving time of the blade member according to the setting degree is “weak”, Some control is performed such as driving for 10 seconds, and driving for 40 seconds if “strong”. In such a rice sharpener, even if the replacement time of the consumable parts is set to be every year, the wear degree of the consumable parts varies depending on the drive time depending on the setting degree. Determining by date is not accurate.
[0007]
The present invention solves the above-mentioned problems, and aims to accurately notify the user that the maintenance time and the replacement time of consumable parts have been reached, and to prevent deterioration in device performance and device failure. Yes.
[0008]
[Means for Solving the Problems]
In order to solve the above-mentioned object, the rice sharpener of the present invention adds the amount of rice to be cut at the rice-toe portion as an added value of the added rice amount by the adding means, determines the value by the determining means, When the value reaches a predetermined value, the display means can display the value.
[0009]
As a result, even if the user is not conscious of the maintenance time or the replacement time of consumable parts, the display means will display and notify when the time has been reached if the user continues to use it. Can be appropriately handled by the user.
[0010]

[0018]
【Example】
Next, specific examples of the present invention will be described.
[0019]
Example 1
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.
[0020]
FIGS. 1 and 2 show a specific configuration of the rice sharpener of the present invention. The main body 1 includes a rice hopper 2, a weighing unit 3, a rice cutting unit 4, a driving device 50, a rice bran suction unit 5, an opening 40, and a rice receiver. 6 and a display operation unit 7.
[0021]
The rice hopper 2 stores rice before rice cutting, and the bottom portion thereof is inclined so that the rice is collected in the weighing unit 3 arranged in the lower part.
[0022]
As shown in FIG. 3, the weighing unit 3 is arranged so that the weighing basket 9 is sandwiched between the upper weighing lid 8 and the lower weighing lid 10, and is configured to rotate the weighing basket 9 through the gear 11 when the weighing motor 12 is driven. ing. The upper weighing lid 8 is provided with two rice supply ports 8a as shown in FIG. Further, as shown in FIG. 5, the weighing rod 9 is provided with four hook portions 9a and four non-hook portions 9e, and the lower weighing portion 10 is provided with two slits 10a as shown in FIG. It has been. Since the upper weighing lid 8 and the lower weighing lid 10 are arranged so that the rice supply port 8a and the slit 10a are perpendicular to each other, when the weighing rod 9 sandwiched between them rotates, the rice bran is placed under the rice supply port 8a. When the portion 9a comes, rice from the rice hopper 2 is supplied therein, and conversely, when the non-ridge portion 9e comes, the supply of rice is cut off. And when the ridge part 9a comes on the slit 10a, the rice in the ridge part 9a falls to the lower part through the slit 10a. For example, if the volume of the hook 9a is set to 1/8 of 0.5, here, the hook 9a rotates twice on the rice supply port 8a and the slit 10a each time when the measuring hook 9 rotates once. Since it passes, weighing 0.5 can be performed.
[0023]
As shown in FIG. 3, the rice edge portion 4 is constituted by a removal inner container 13, a removal outer container 14, a blade member 15, and a rotating shaft 16 having small holes. The container 13 inside the removal is a part for receiving the rice weighed by the weighing unit 3, and a blade member 15 that is a rotating body and a rotating shaft 16 are disposed in the inside. The blade member 15 is attached to the rotating shaft 16, and the blade member 15 also rotates when the rotating shaft 16 rotates. Since the inner container 13 has a small hole, when the blade member 15 rotates, the rice stored inside is agitated, and the rice adhering to the surface is removed to remove the inner container 13. It is discharged outside. Since the outer container 14 is outside the inner container 13, the soot inside the inner container 13 is discharged to the outer container 14.
[0024]
The driving device 50 is a motor, and rotates the rotary shaft 16 through a belt or a pulley.
[0025]
The rice bran suction part 5 plays a role of sucking and storing the rice cake discharged in the outer container 14. Specifically, the removal outer container 14 is provided with a discharge port, vacuum suction is performed from the discharge port, and the soot is discharged from the inside of the removal removal container 14 and passed through a paper pack used in a vacuum cleaner. , I will save the bag.
[0026]
The opening 40 is attached to the inner container 13 for removal, and is composed of the opening valve 17 of FIG. 3 and the solenoidoid 18 that opens and closes the opening valve 17. When the blade member 15 is rotating and the opening valve 17 is closed, the rice is removed as described above. However, when it is open, the inside rice is gathered outside by centrifugal force, so the container inside the removal 13 is discharged outside.
[0027]
The rice tray 6 is a container for storing rice discharged from the opening 40.
[0028]
As shown in FIG. 6, the operation unit 7 has a display unit such as an LED and an operation switch, and is configured with a control device for controlling those signals. The user operates this operation switch to give a signal to the control device, and the microcomputer installed in the control device controls the load of the drive device 50 and the like by a preset process program. . Thus, the microcomputer has the function of the control means.
[0029]
Further, the operation of this microcomputer will be described with reference to the flowcharts of FIGS. In S <b> 1, the user uses the total number setting switch 27 to set the amount of rice binding in increments of 0.5 and displays the set amount of rice binding on the total number display LED 20. When the setting is completed, the process proceeds to S2, and the user operates the start switch 28 to start operation. In S3, the set rice amount set by the user at this time is stored as Sg, and the completed rice amount Ng is set to zero. Here, since the setting can be made in units of 0.5, it is assumed that the doubled numerical value is stored so that numerical processing is easy. For example, if the setting is 2.5, the doubled 5 is stored as Sg. In S4, the metering unit 3 is operated to perform 0.5 metering. The weighed rice is sent to the rice fork 4. In S5, the blade member 15 is rotated to remove the hair. At this time, the soot suction unit 5 is also operated to suck and remove the soot, and the sucked soot is stored in the paper pack. When the blade member 15 is rotated for a predetermined time, the process proceeds to S6, the opening 40 is opened while the blade member 15 is rotated, and the rice in the rice binding portion 4 is discharged. In S7, 1 is added to the completed rice amount Ng. In S8, this Ng is determined, and it is determined whether or not it is equal to the set rice stitch amount Sg. If they are not the same, the process returns to S4, and if they are the same, the process proceeds to the next S9.
[0030]
In this way, the operation of S4 to S7 is repeated Sg times. For example, if the set amount of rice is 2.5 go, weigh 0.5%, remove rice, and discharge rice by 2.5 Will be repeated 5 times. In S9, the total number of operations Nt, which is the amount of added rice, is calculated. That is, in this example, since the operation is performed by weighing rice per unit amount, the number of operations is the same as the amount of rice that has been broken. Therefore, if the number of times of driving up to immediately before the current driving is Nt0, Nt adds the set rice amount Sg having the same meaning as the number of times of driving this time to Nt0. In this way, the adding means is realized by the microcomputer. In S10, this Nt is determined. If this Nt is equal to or greater than the determination value K1, the process proceeds to S11, the paper pack replacement LED 25 is turned on, and if it has not reached K1, the process proceeds to S12, and the paper pack replacement LED 25 is turned off. Let In this way, the determination unit is realized by the microcomputer, and the paper pack replacement LED 25 is a specific example of the display unit. In S13, the operation of the load is stopped and the operation is terminated.
[0031]
Thus, since the amount of rice cutting by the user is added as the total operation number Nt at the time of operation, the value at which the paper pack of the straw suction unit 5 becomes full is set as the determination value K1 in the memory of the microcomputer. If Nt reaches that value, the paper pack replacement LED 25 is lit to indicate that the replacement time has been reached. For example, if K1 is set to 200 (the amount of rice binding is 100), the paper pack replacement LED 25 is turned on when the total number of operations Nt becomes 200 or more.
[0032]
In this example, the paper pack replacement is used. However, even when the consumption time of the consumable parts such as the rotary blade 15 is notified, it can be displayed and notified based on the same reason.
[0033]
In this example, the total operation number Nt is added after the operation is completed, but this may be added at the start of the operation. In short, the number of times used by the user or the amount of rice that has been cut is added as an additional amount of rice, and the result is determined and displayed.
[0034]
(Example 2)
In the second embodiment, a plurality of determination values determined by the determination means are provided in the rice sharpener according to the first embodiment, and the display means performs display according to the determination values. The operation of the microcomputer of the second embodiment will be described with reference to FIG.
[0035]
FIG. 8 is obtained by adding the processes of S14 and S15 after the total operation number Nt determination process of S10 to FIG. 7 used for explaining the operation of the microcomputer in the first embodiment. That is, the total number of operations Nt is determined by the determination means in S10, and if this Nt is greater than or equal to the determination value K1, the process proceeds to S11, the paper pack replacement LED 25 is turned on, and if it has not reached K1, the process proceeds to S14. In S14, the total operation number Nt is determined again. If this Nt is equal to or greater than the determination value K2, the process proceeds to S15, and the paper pack replacement LED 25 blinks. If not, the process proceeds to S12, and the paper pack replacement LED 25 is reached. Turn off the light. In S13, the operation of the load is stopped and the operation is terminated.
[0036]
In this way, the amount that the user cuts the rice is added as the total operation number Nt during operation, and compared with the determination values K1 and K2, and when Nt reaches K2, the paper pack replacement LED 25 blinks. When K1 is reached, the lighting display can be performed. For example, if K1 is set to the amount that the paper pack is full = 200 (rice binding amount is 100 go), and K2 is set to be the amount that the paper pack reaches the eighth minute = 160 (rice binding amount is 80 go), the total operation When the number of times Nt reaches 160, the paper pack replacement LED 25 is first blinked. When the number Nt reaches 200 or more, the paper pack replacement LED 25 is lit. When the paper pack replacement LED 25 starts blinking in this way, it can be notified that the paper pack replacement time is approaching, and when the used paper pack replacement LED 25 is turned on, it is notified that the replacement time has been reached. be able to.
[0037]
In this example, two determination values are provided. However, a plurality of determination values such as K3, K4... May be provided after the determination of K2. In that case, there is an effect that the time of replacement can be notified in detail.
[0038]
In this example, the paper pack replacement LED 25 is turned on or blinked, but the brightness may be changed. In short, it is possible to display according to a plurality of judgment values.
[0039]
(Example 3)
The third embodiment is configured so that the degree of rice cutting can be set in the rice sharpener according to the first embodiment, and the total number of operations Nt according to the setting degree can be obtained. . The operation of the third embodiment will be described with reference to FIG.
[0040]
In FIG. 9, the contents of the flowchart of FIG. 7 used for explaining the operation of the microcomputer in the first embodiment are partially changed, and description will be made based on the changed points.
[0041]
First, in S1, in addition to setting the amount of rice cutting, the level of rice cutting can be set by the rice cutting level switch 22. This setting status is displayed on the rice cutting degree display section, and “None” LED 21a means that rice cutting is not performed, “Weak” LED 21b means that rice cutting is performed weakly, and “Rice cutting” is performed as standard. The “standard” LED 21c and the “strong” LED 21d in the sense that the rice tong is performed more strongly, and any one of the selected LEDs is lit and displayed.
[0042]
In S3, a set of weight values L according to the set degree of rice cutting is added. Here, 0 is set as the weighting value L if the selection of the degree of rice cutting is “none”, 1 is set if “weak”, 2 is set if “standard”, and 4 is set if “strong”.
[0043]
In S5, the vanishing by rotation of the blade member 15 is performed, but the time for shifting to S6 is changed depending on the degree of rice cutting. Here, if the degree of rice cutting is “none”, 0 seconds, “weak” is 10 seconds, “standard” is 20 seconds, and “strong” is 40 seconds, and then the process proceeds to S6. .
[0044]
In S9, the total number of driving times Nt is calculated by adding the product of the set rice stitch amount Sg and the weighting value L to the previous number of times Nt0. That is, the calculation “Nt = Nt0 + (Sg * L)” is performed.
[0045]
As described above, when the degree of rice cutting is set, the operation in the removal of S5 differs depending on the degree of rice cutting. For example, a 40-second operation with a “strong” degree of rice cutting uses four times as many rice-shearing parts 4 and a spear suction part 5 as a “weak” 10-second operation. It ’s easy to imagine that it ’s easier to keep using it.
[0046]
However, in this example, the weighting value L corresponding to the degree of rice stitching is set, and the total number of operations Nt, which is the amount of added rice corresponding thereto, is calculated. Lighting time can be done accurately.
[0047]
In this example, the time for shifting from S5 to S6 was changed according to the degree of rice cutting, but this may be a change in rotational speed of the blade member 15 instead of a change in time. In short, the addition value calculation of the amount of added rice corresponding to the change of the operating condition by setting the degree of rice cutting can be performed correspondingly.
[0048]
(Example 4)
In the fourth embodiment, weight change means is provided so that the value of the weight value L can be changed later in the rice sharpener according to the third embodiment. For example, in the third embodiment, the weighting value L is set to 0, 1, 2, 4 in the order of “none” to “strong”. It can be changed to values such as 1, 2, 3, and 4 by providing and disconnecting. As a result, even if the time required for removal is changed in the third embodiment, the weighting value L can be appropriately set, and the calculation of the total operation number Nt (Nt = Nt0 + (Sg * L)) can also be handled. It is.
[0049]
The jumper line is used as the weight changing means, but there are many other means such as a change by a memory outside the microcomputer and an input voltage value to the AD input of the microcomputer.
[0050]
(Example 5)
In the fifth embodiment, in the rice shears according to the first or second embodiment, determination value changing means is provided which can change the determination value determined by the determination means later. For example, in the second embodiment, the determination value K1 is set to 200 and K2 is set to 160. By using these values as the determination value changing means, jumper wires on the control device are provided, and 300, It can be changed to a value such as 260. Thereby, even if the capacity of the paper pack is changed in the rice cutter of the second embodiment, the determination value can be changed, so that it can be flexibly handled.
[0051]
Although the jumper line is used as the judgment value changing means, there are many other means such as a change by a memory outside the microcomputer and an input voltage value to the AD input of the microcomputer.
[0052]
(Example 6)
In the sixth embodiment, in the rice stirrer according to the first or second embodiment, the control means prohibits part or all of the control of the load from the result determined by the determination means. It is. The operation of the microcomputer of the sixth embodiment will be described with reference to FIG.
[0053]
In FIG. 10, the contents of the flowchart of FIG. 7 used for explaining the operation of the microcomputer in the first embodiment are partly changed, and description will be made based on the changed points.
[0054]
S16 is inserted immediately after the start of operation in S2, and the control prohibit flag is determined here. If this flag is not set, the process proceeds to S3. If it is set, the process after S3 is not performed, and the process of S13 is performed. Complete the operation.
[0055]
S17 is inserted after the calculation of the total operation number Nt. Here, Nt is compared with the determination value C1, and if Nt does not exceed the value, the process proceeds to S13 to complete the operation, but if it exceeds, the process proceeds to S18. Then, the control prohibition flag is set and the process proceeds to S13.
[0056]
As described above, when the total operation number Nt reaches C1, the control prohibition flag is set and the operation is completed. Therefore, even if the operation is started thereafter, it can be rejected. The judgment value C1 is usually set to a value that is equal to or greater than K1, which is a judgment value for consumable parts replacement and maintenance, so it is used here while notifying that the replacement time has been reached at K1. In the case of continuing, in order to prevent a failure of the device, the operation can be performed so that the operation cannot be performed when C1 is reached.
[0057]
(Example 7)
The seventh embodiment is a specific example of the notification means and the control means prohibits a part or all of the control of the load from the result determined by the determination means in the rice sharpener according to the sixth embodiment. A buzzer is provided to notify that control is prohibited. The operation of the microcomputer of the seventh embodiment will be described with reference to FIG.
[0058]
In FIG. 11, the process of S19 is added to the contents of the flowchart of FIG. 10 used for explaining the operation of the microcomputer in the sixth embodiment. S19 is inserted into the branch destination after the control prohibition flag is set in S16. Here, the buzzer on the control device is sounded, and the process proceeds to S13.
[0059]
As described above, when the user tries to start driving, if the control prohibition flag is set, the driving is rejected. However, since the notification is performed at the same time, the user can be informed why the driving is rejected.
[0060]
(Example 8)
In the eighth embodiment, an initializing means for initializing the total number of operations Nt is provided in the rice stirrers according to the first to seventh embodiments.
[0061]
In the above embodiment, when the total number of operations Nt reaches the determination value K1, the paper pack replacement LED 25 is lit. At this time, when the paper pack clear switch 23 of FIG. Set to 0. As a result, Nt falls below the determination value K1, so the paper pack replacement LED 25 is turned off.
[0062]
As described above, when a predetermined treatment such as replacement of the paper pack is completed, the total operation number Nt can be initialized and the operation can be continued as usual.
[0063]
【The invention's effect】
