Background technology
Many known various devices that the raw-material epidermis that separates various cereal arranged and this raw-material seed carried out pearling.As having epidermis and its content being carried out pearling and the cereal that utilizes, rice, wheat, beans etc. are arranged as everyone knows, as the device of the pearling of carrying out cereal, rice mill is a typical example.Exist as everyone knows multiple food materials can be because of the degree of the separation of the epidermis of cereal, be that the degree of the situation of peeling off on the surface of cereal changes and causes mouthfeel, taste different.In addition; Milling degree be meant amount that resulting amount after yield rate that is the pearling is original with respect to raw material etc. ratio (for Mi Eryan; Be also referred to as pearling rate or husk rice degree), can be by degree (for rice, the degree of the husk rice=husk rice degree) expression of this pearling.
When rice was described, the brown rice before the husk rice was followed successively by endosperm, delicious layer (inferior aleurone) and chaff layer (flesh chaff, kind skin, epidermis etc.) from center, when forming rice when carrying out husk rice, removes the chaff part except the flesh chaff.Afterwards, utilize water to carry out grinding operation usually, eliminate the flesh chaff thus.But at this moment, delicious layer also possibly come off.Minimizing utilizes the grinding operation of water and stays delicious layer, and the desirable machining state of rice is equably the brown rice surface to be carried out husk rice and only removed the chaff layer, and stay the delicious food layer (inferior aleurone) on the endosperm surface that is positioned under the chaff layer.
On the other hand, under state, because of the reason of chaff flavor, tarnish etc. causes being difficult to experience delicious food because of the insufficient and residual chaff of husk rice.In addition, when under this state, preserving, oxidation is too fast, and when after cooking, being incubated, rice turns to be yellow slightly.In addition, under the situation of excessively husk rice (husk rice is too much), be difficult to experience delicious food, the distinctive sweet taste of rice, the delicious disappearance.
This type of carries out the simple and easy and small-sized rice mill of husk rice automatically, and is open by the TOHKEMY 2011-062701 communique of the application applicant's application for example.This rice mill is called as the rice mill of following so-called agitating type: while in having the husk rice basket of a plurality of sorting holes, make blade, bar-shaped mixing part rotate and stir the chaff of rice stripper surface, the sorting hole of this chaff of being stripped from through the husk rice basket is separated between container and the husk rice basket.
Understanding on the basis of the present invention, the structure of the above-mentioned rice mill of needs is explained more specifically with reference to Fig. 8.
Fig. 8 is the exploded view of the major part of existing rice mill.The 5th, take in the tubular of rice (be often referred to be used to carry out brown rice, rice washing rice etc.); The husk rice basket of mortar type shape particularly; The 9th, through rotating the rotation stirring body that stirs the rice in the husk rice basket 5; 6 take in husk rice basket 5 and take in the chaff box (chaff collector) of the tubular that is made up of for example PP resin of the chaff that utilizes husk rice basket 5 and peel off from rice, and the 30th, take in the chaff box storage case of the tubular that constitutes by for example ABS resin of chaff box 6.When husk rice; Under the state in the chaff box storage case 30 that chaff box 6, husk rice basket 5 and rotation stirring body 9 is installed on body shell 11; The brown rice of desirable amount is dropped in the husk rice basket 5, under the state that covers lid 3, begin, carry out husk rice thus by operating portion indication husk rice.

Therefore, how the kind etc. that discloses rice no matter at following document changes the rice mill that can both obtain desirable pearling rate.
For example, No. 2626924 communique of Japan Patent (patent documentation 2) discloses circulating rice mill and yield rate is confirmed devices for husking rice.In this patent documentation 2, according to initial input amount with obtain the yield rate situation of husk rice operation in the weight in each correct time, when the yield rate of operation reaches the hope yield rate of initial setting, stop rice mill.This disclosed rice mill that kind shown in title is circulating, utilizes partition wall separating cycle formula to stockpile chamber and chaff discharge chamber (Fig. 2 of patent documentation 2), enters into the chaff that chaff is discharged the chamber through partition wall, maintains the original state and discharges from the chaff outlet.Owing to upload at dosing machine and to put rice mill, the rice mill that therefore utilizes the amount according to the chaff of discharging to lighten is judged its yield rate.
But; This rice mill is to discharge through chaff is maintained the original state according to the whole gross weight of the corresponding rice mill that lightens to measure yield rate; Therefore can not be applied to the so-called one-piece type rice mill of following general home-use that kind, that is: after husk rice separately processing itself pearling reach the rice of needed pearling rate and the chaff of therefrom removing.
On the other hand, the one-piece type rice mill that can use in the family that is used to obtain desirable yield rate is disclosed in TOHKEMY 2003-38967 communique (patent documentation 3).The rice sector of this rice mill; In container, can take in separation basket with a plurality of sorting holes with the rotating shaft that utilizes motor and rotate with packing into or take out; In separating basket, utilize this rotating shaft to make the stirring parts rotation; Make chaff be separated to container and separate between the basket while stirring rice, carry out the processing of rice with this through the sorting hole that separates basket.Patent documentation 2 is provided with the drive current that detects motor, promptly drives the device of drive current of the motor of the rotating shaft that makes stirring parts (Stirring device) rotation at this known rice sector.This drive current changes the size of the load that stirring parts bears according to the amount of the rice that stirs; Therefore will with add corresponding drive current as index; According to the weight of the rice in the separation basket that reduces based on eliminating, different with the drive current that weight produced that drops into initial rice, the variation of the weight of inferring meter, be yield rate because of chaff.
But because load current may not be constant, its load is according to the state of brown rice such as moisture rate, stirring and than cataclysm; Need obtain the mean value of drive current; Remove the processing of noise of producing evaluated error and so on, therefore may not be easy, also big to the influence of cost.

The upside load relay part 105 of the ring-type shown in Fig. 2 A is set at hollow protuberance 30d and between the hollow protuberance 6g cylindraceous and be between the bottom 30b of bottom 5m and chaff box storage case 30 of husk rice basket 5; The internal diameter of upside load relay part 105 is slightly larger than the profile of hollow protuberance 30d; Therefore its external diameter can move freely in the gap between hollow protuberance 30d and the hollow protuberance 6g of cylinder less than the internal diameter of the hollow protuberance 6g of cylinder along the vertical direction.
(Fig. 3 A, 3B are cutaway view to elongated support plate 104a shown in Fig. 2 C; Therefore do not observe); Hole through near the setting of the bottom 30b the hollow protuberance 30d of chaff box storage case 30; And between hollow protuberance 30d and the hollow protuberance 6g of cylinder, extend, and combine with upside load relay part 105.
When with reference to Fig. 3 B and Fig. 4 B; Be provided with the cylindrical wall 5k that between hollow protuberance 6g of cylinder and hollow protuberance 30d, extends from the under(-)chassis of husk rice basket 5 towards upside load relay part 105; On upside load relay part 105, load husk rice basket 5 via cylindrical wall 5k, whole thus load puts on upside load relay part 105.The end of the hollow protuberance 6g of cylinder and the bottom surface of husk rice basket 5 utilize support plate 104a and guarantee the gap; So that upside load relay part 105 is according to the variation of the weight of husk rice basket 5 and move freely along the vertical direction; In addition; The length of adjustment support plate 104a so that upside load relay part 105 does not contact with the bottom 30b of chaff box storage case 30, is guaranteed the gap between the bottom 30b of upside load relay part 105 and chaff box storage case 30.
Identical ground between the top of lid 3 and husk rice basket 5, also guarantee the gap between the top of husk rice basket 5 and the chaff box 6, utilizes this gap to assure the free state of husk rice basket and guarantees the precision of weight sensor.
In addition; The degree that the Mi Buhui of constriction after the pearling flies out between lid 3 and the husk rice basket 5, preferred settings below 2mm, between husk rice basket 5 and the chaff box 6 also constriction when chaff can not utilize husk rice air-flow and disperse; Preferred settings and constitutes the shape of chaff box with this below 2mm.
Though utilize the situation of strain gauge to be illustrated to above-mentioned load transducer, also can use its other load transducers, for example, piezoelectric element etc.And, also can its shape be formed circular and bear from the load of husk rice basket (pearling container) directly or indirectly and measure its weight.
When husk rice basket 5 was described, the existing husk rice basket that has been illustrated with reference to Fig. 8 covered mesh whole of side perimembranous, and desire utilizes this whole face to peel off the rice that is stirred and flies up.On the other hand, in the husk rice basket that the rice mill based on the application example uses, mesh only is formed at the downside periphery, is the lower portion in the side perimembranous, and is not formed at upper periphery.This is because following reason: the gravimetry to based on the husk rice of stirring experimentizes; The result finds because of there being the relation in gap between husk rice basket 5 and the chaff box 6; Particularly the husk rice amount after a little while (1 close or 2 close about) rice disperse to basket top; Therefore the air-flow of the chaff that mesh flows out from top during because of husk rice is to the top diffusion and be attached to lid, the chaff of perhaps falling the chaff box enters into husk rice basket 5 from the mesh on the top of husk rice basket 5 because of ascending air inside; Therefore the top with husk rice basket 5 forms the state that mesh stops up, thereby prevents to circulate and the chaff that rises enters into the inside of husk rice basket 5.That is, analyze to the husk rice amount can not receive too big influence for a long time, but under the situation of carrying out a spot of especially husk rice, circulation and the weight of chaff that enters into the inside of husk rice basket 5 can increase the weight in the husk rice basket 5 causes measure error obvious.Therefore, in the husk rice basket 5 that rice mill of the present invention 1 uses, top 5a does not form mesh in side week, and face forms the face of smoother within it, and only the 5c periphery is provided with the mesh of friction rice from the roughly middle part of side perimembranous short transverse to the bottom.The height of the target that mesh zone is set degree of burying during for the brown rice of the maximum husk rice amount (5 close) of packing into.Thus, the chaff of being stripped from is fallen in the chaff box 6 and reduce the error of weight.In addition, mesh not only can be arranged at the side perimembranous of basket, also can be arranged at the bottom surface sections of husk rice basket 5.In addition, also can utilize independent lid (inner cap) to cover the upper opening of husk rice basket 5 as required.Through covering the husk rice basket, the dispersing of the chaff that can more effectively prevent ascending air and caused particularly can be avoided chaff adhering to the upper flange portion of husk rice basket.In addition, the inner cap under this situation only covers the husk rice basket, can keep certainly and the chaff box between the gap.
At side Zhou Peishe a plurality of (4) the bellying 5n of the cylindrical wall 5k of the bottom of husk rice basket 5, loosening chimeric with the slot part 6m of the hollow protuberance 6g of chaff box 6.Play following effect thus: even rotation stirring body rotation in operation process; The cylindrical wall 5k of husk rice basket 5 and the slot part 6m butt of chaff box and make husk rice basket 5 rotation; Husk rice basket 5 is state freely with respect to the chaff box under halted state, can not influence weight measurement.
In addition; If husk rice basket (pearling container) has above-mentioned functions; Then not necessarily need form the woven wire shape, also can be to form a plurality of holes and mode that can stripper surface also discharges this material of peeling off from this hole this husk rice basket (pearling container) in.In addition; In this example; Though the structure that rotation stirring body 9 is installed on the pearling container is illustrated, also can adopt to be installed on the structure that loam cake 3 waits structure or the utilization of other positions generation different with the rotation stirring body of embodiment to carry out pearling based on the agitating unit of compressed-air actuated rotation torrent and also can be applied.
Fig. 7 is illustrated in that this rice mill at first uses is used to stir the rotation stirring body 9 of the new shape of husk rice.Though this new rotation stirring body 9 is four structures that tabular mixing part 9b extends at the equal angles interval that TOHKEMY 2011-062701 communique specifies of that kind shown in Figure 9, only its leading section is crooked towards the rear with respect to direction of rotation.This is can be in the husk rice amount less be 1 close ~ 2 suppress excessive centrifugal force when closing the left and right sides, disperse or suppress ascending air to the top of husk rice basket 5 thereby suppress rice.Thus, can further suppress chaff and be attached to lid, the situation from being dispersed by the chaff box taken in, the error of husk rice rate also can reduce.Owing to only make the front end position crooked, the face of pushing most rice forms the plane of not having crooked straight wire, therefore also can guarantee husk rice amount pressing force for a long time, also can realize as initial purpose between short-term in carry out husk rice.
Then, the action to rice mill describes.With reference to Fig. 5, guidance panel (operating portion) 70 has: be used to set the husk rice pattern mode button 71, be used to indicate beginning, the beginning/stop button 75 that stops of husk rice action and be used for replacement button 76 weight initialization (0 adjustment).Pattern comprises plumule rice pattern, boils brown rice, clean rice (brown rice), clean rice (rice), FRESH, husk rice pattern soon, and each pattern is shown that 73a is arranged at guidance panel (operating portion) 70.The a plurality of indicator lamps (indicator lamp of ▽ shape) that are used to indicate each pattern are corresponding with each pattern and be arranged at liquid crystal display picture 77, and these a plurality of indicator lamps are used to represent that which pattern is set.The selection of pattern forms presses mode button 71 and switching successively at every turn, and for example, when being in the pattern of plumule rice, the indicator lamp on the pattern of plumule rice next door is lighted, and when pressing mode button 71, next indicator lamp is lighted, and indication switches to boils brown rice soon.And, when " husk rice pattern " in the selection pattern,, prepare to show the Verbose Mode of " 003 minutes 05 minutes 07 minutes zero rice zero first-class rice " that 73b representes by Verbose Mode as more detailed husk rice rate.Here, " zero " expression branch of smashing, smash in 2 minutes in 1 minute etc. between the show value is smash pattern.Promptly; When with pattern display floater 73a on the relative indicator lamp of husk rice pattern show when lighting; Right, left play button 74 becomes effectively so that can select the Verbose Mode of the finer husk rice rate of its " 003 minutes 05 minutes 07 minutes zero rice zero first-class rice ", with its arrow accordingly; Light with the corresponding indicator lamp of selecting of Verbose Mode, know the detailed husk rice rate of oneself selecting thus.
Following table 1 illustrates the setting of the husk rice rate (weight/input after essence is smash (essence is smash preceding) weight * 100 (%)) in each pattern.

In that epidermis is separated and carries out under the situation of boiling the brown rice pattern soon of husk rice from brown rice immediately, so long as 99.6% husk rice rate gets final product.In addition, carrying out the process of husk rice to rice from brown rice, experiment according to the present invention is preferably 91% husk rice rate.At this moment, carried out the experiment of 7 kind, the result finds that broken rice rate (weight * 100 (%) of the weight/rice of cracking rice (essence is smash the back)) is suppressed at below 2%.And,, smash, smash in 5 minutes in 3 minutes and husk rice rate that 7 minutes smash is set at 97%, 95%, 93% respectively for plumule rice.In addition, under branch is smash pattern, be refined as according to 1% dividing (for example, smash in 1 minute be smash in 99%, 2 minute to be that to smash in 98%, 4 minute be that to smash in 96%, 6 minute be 94% etc.).In addition, under the pattern of " first-class rice/clean rice (brown rice) " that further improves the husk rice rate, husk rice is so-called first-class rice via rice from brown rice, and the husk rice rate of first-class rice is set at 89%.That is,, therefore be equivalent to clean rice because first-class rice is the rice to the chaff that is further stirred and remove the surface by the rice after the husk rice immediately.Clean rice is meant the rice that need not the water cleaning and directly can cook.But according to the situation of clean rice, owing to pay attention to going chaff, the rotating speed that therefore turns round, the duration of runs are different.In addition, " (brown rice) " is meant input brown rice.
In addition, in based on rice mill of the present invention, append the operation and the operation of " FRESH " (grinding) pattern of grinding that form " clean rice (rice) " pattern of clean rice from rice.Promptly; Because the husk rice rate is represented by the husk rice amount (weight) in the input moment and the ratio of the husk rice amount (weight) after the husk rice; Therefore the Mi Weibi that drops into must be a brown rice; Because also exist the person of utilization to be intended to form from rice the situation of clean rice, therefore the pattern at guidance panel 70 shows preparation " clean rice (rice) " pattern on the 73a.Under the situation of the FRESH pattern of grinding, for example after wash rice under the situation in elapsed time, the oxide layer on the flake off of surfaces, the situation of getting rid of dirt are effective immediately.Therefore, the rice of input can be not necessarily brown rice, rice, prune about 0.3% surface of expression.
In addition, with respect to the husk rice rate that can allow of the reality of each husk rice rate, be desirable though reduce difference as far as possible, be generally+/-1%, that is, allow in the scope of husk rice rate 90 ~ 92% in the setting with respect to 91% under the rice pattern.But, allow difference to be not limited thereto, also can be according to changing based on the precision of the gravimetry of the microcomputer of control circuit, the precision that load transducer is measured mechanism 100.In addition, in the FRESH pattern, boil under the brown rice pattern soon,, allow difference littler with this its because the time of stirring is short, for example, preferably with respect to the husk rice rate of setting further in+/-0.2% scope.
Then, control circuit and husk rice action based on rice mill of the present invention are described.Fig. 6 is the functional block diagram of the control circuit (control part) 80 of (Reference numeral 8 according to Fig. 8 of existing rice mill is represented as a reference) in the control circuit box.Control circuit 80 has the motor drive circuit 88 that microcomputer 81 and motor 10 is carried out drive controlling.Microcomputer 81 also has input and output (I/O) circuit 82, CPU83, memory (ROM, RAM) 84 that supplies load transducer 102 connections and the bus 85 that connects them except having guidance panel 70, velocity sensor 86 and motor drive circuit 88.In memory 84, preestablish or enroll: the rotary speed of the mixing part of each the husk rice rate corresponding with the husk rice amount (by utilize PWM than the motor that gives drive the mixing part of setting rotary speed, ± about 20 rev/mins error precision) and husk rice time (rotational time of mixing part, ± about 2 seconds error precision).
Then, mainly the action of the husk rice of the situation that drops into brown rice is described.When the attaching plug of rice mill 1 inserts outlet; Microcomputer 81 is carried out initialized program; Load is transmitted to support plate 104a, load transfer function portion 103 and load transducer 102 from the upside load relay part 105 of Fig. 2 A successively; These load transducer 102 signals corresponding with distortion that produced transmit to the microcomputer 81 of Fig. 2; Whether inspection arrives with the suitable signal of when dispatching from the factory, setting of the weight that comprises the husk rice basket 5 that rotates stirring body, and opens liquid crystal display picture 77.
If under the situation that does not detect the weight that is equivalent to comprise the husk rice basket 5 that rotates stirring body; The picture of then noting liquid crystal display picture 77 display alarm users on the other hand, is detecting under the situation that is equivalent to its weight; Then display reminding drops into the picture of rice, for example " please drop into brown rice.Measure weight ", the prompting user drops into brown rice.
When dropping into actual brown rice, measure its weight, and inspection whether be equivalent to regulation that rice mill can handle close number with interior weight, if under the less situation of brown rice, continue to show shown " please drop into brown rice.Measure weight ", prompting further drops into.Otherwise; Under the more situation of brown rice; Utilize the wrong warning that shows the attention that the display alarm input amount is too much at liquid crystal display picture 77, and check whether be the interior weight of scope that is limited in regulation, proceed this warning and handle in the scope that is limited in regulation.
Under the situation in being restricted to the scope of regulation, show the result of its gravimetry, and be used to measure 0 adjustment (calibration 0g) of the essence amount of smashing (husk rice rate).In addition, though need not to use the starting stage to carry out,, therefore also can press replacement button 76 and carry out the 0g calibration in each husk rice action because the mixing part, the husk rice basket can be correspondingly aging year by year with frequency of utilization at body.Show the number that closes after being equivalent to husk rice respectively according to each husk rice rate under each pattern at liquid crystal display picture 77, what the number that closes the user can drop in the input stage under at length the pattern that is held in hope thus.
Then, actual when pattern that the user selects to hope, show and number is closed in the corresponding husk rice rate of this pattern and the expectation that finally obtains.
Rice mill is controlled the rotation of mixing part according to the amount (weight) of the rice that drops into and the pattern of setting.For example; Can form: be redefined for that so-called constant speed that constant rotating speed and time carries out husk rice stirs (low speed rotation) running and in running initially to stir than higher rotation and husk rice; Along with time lapse, while reduce the stirring of successively decreasing (rotation of the successively decreasing) running that its rotary speed turns round.
Successively decrease and stir running except being the running of successively decreasing continuously of slowing down according to the passage of time and with rotating speed linearity or curve property, also exist according to the passage of time and with rotating speed through the running of successively decreasing of one or more snippets stage that slows down.
Details illustration in the table 1 ~ table 10 of TOHKEMY 2011-062701 communique of this running of successively decreasing.Each minute of 1 closing for dropping at this table 1 ~ table 10 ~ respectively the closing number and illustrate 2 fens of the situation of 5 brown rice that close ~ smashing in 8 minutes smashes, and then the activity list to the husk rice of rice, plumule rice is shown.
Illustration by these tables is visible, under the situation of the value of husk rice to husk rice rate bigger " smashing in 5 minutes ", with the husk rice of the chaff layer that forms residual more brown rice, can carry out based on constant speed drive with the mode of peeling off chaff through the height rotation quickly.Even in rotation at a high speed down, the chaff layer of brown rice absorbs impulsive force and is stripped from, but since make the time of mixing part rotation short, produce and crack rice fewly, therefore can stir (low speed rotation) with constant speed and turn round and carry out.Change according to the amount that drops into its duration of runs, for example then enough about 30 seconds if close number 1 lacking about closing, and 5 closing under several situation about closing more, carries out constant speed and stir the time more than 1 minute or 1 minute that operates at.
On the other hand; Forming from brown rice under the situation of plumule rice; In order to improve its plumule rate,, carry out afterwards stirring running with about 1 section or 2 sections stage or continuity the successively decreasing of rotating speed that successively decrease preferably at first to turn round than " smashing in 3 minutes ", " smashing in 5 minutes " low rotation.
Form from brown rice smash in 7 minutes, under the situation of rice; In order to shorten the husk rice time; Preferably initial rotary speed is made as greatlyyer, carries out afterwards stirring running with about 2 sections stage or continuity the successively decreasing of rotating speed that successively decrease than the rotary speed of " smashing in 3 minutes ", " smashing in 5 minutes ".In addition, close 1 ~ 2 the situation of few husk rice amount about closing under because the husk rice amount is few and grain of rice density is little, thus the rice during husk rice fly spout crack rice owing to bump to be easy to produce, so the husk rice time of initial period be made as minimum with lid etc.
After getting into the initial stage, carry out under the situation based on the running of successively decreasing of the stage of two stages, three phases or above numbers of stages; The rotation of initial phase I is to peel off chaff than higher rotation quickly; Rotary speed in next stage through the mixing part of slowing down; Make the direction of rotation (grain of rice sense of rotation separately) of rice change, so the surface of the chaff layer of brown rice is peeled off equably.The husk rice time rotates to second rotation from first and prolongs slightly, when in the roughly the same time, carrying out husk rice, produces the effect of grinding rice, goes chaff well and the generation that also can suppress to crack rice.
Like this; According to husk rice amount and husk rice rate; Existence may not be carried out the situation of the above operation of three phases, three phases, therefore for each close number with the mode that can realize husk rice, rice washing, grinding based on the operation in a stage, two stages in memory 84 storages of rice mill or enroll program.
For rice mill based on the application's inventive embodiment, carry out with from 1 be incorporated into 5 close each close the corresponding programmings of number so that the execution husk rice operation identical with the table 1 ~ table 10 of TOHKEMY 2011-062701 communique.Wherein, do not have weak, standard and strong classification, only be set with the husk rice operation of standard for rice and plumule rice.In addition, also set each pattern of brown rice, clean rice and the pattern of FRESH (grinding) of boiling soon,, therefore various modes can be installed owing to haveing nothing to do with the rice kind and can directly measuring the husk rice rate.Can directly measure the so-called closed-loop path of yield rate controls owing to utilization of the present invention; Therefore do not need above-mentioned weak, standard and strong notion; If the husk rice rate is replaced with the for example numerical value of rice, zero, first-class rice, then can realize the setting of multiple milling degree.
Below shown in table 2 and table 3 be corresponding with the table 5 of TOHKEMY 2011-062701 communique and table 10 and in the operation of setting based on the rice mill 1 of the application's invention.
[table 2]
[table 3]
The pattern that drops into brown rice, select to hope as the user, and during starting operation is carried out basically the husk rice running according to this operation.Here, in the last stage, for example if be the phase III based on the husk rice of three phases; If the husk rice in a stage (for example is before the running that finishes first stage; Before about 20 seconds ~ 10 seconds), temporarily stop husk rice, and measure the weight among the husk rice basket 5; Poor according to the amount of initial input when measuring calculated the husk rice rate when temporarily stopping.Then, relatively the husk rice rate of this husk rice rate that calculates and target is calculated the husk rice that whether also needs the time of which kind of degree.According to after the husk rice condition in moment of stopping begin the husk rice operation and carry out the husk rice of this time that calculates.But, also can be guaranteeing the shortening time under the prerequisite more than needed, not carry out excessive husk rice.Then, if gravimetry and calculate its husk rice rate once more after the end of this husk rice under the situation that also needs husk rice, carries out the husk rice according to the time that difference determined of this husk rice rate once more.Therefore, because be used to reach time of husk rice rate of target according to the amount of the rice of the quality of rice, input all different at every turn, so time and representing as a reference total time of table 2, table 3.
Because the value of the husk rice rate of " boiling brown rice soon ", " plumule rice " is big, therefore can use the operation that constant speed stirs (low speed rotation) running.And, replace dropping into brown rice, rice forms the pattern, FRESH of clean rice, promptly to grind the value of husk rice rate of pattern on surface of the rice that drops into all big owing to drop into, and about 30 seconds the constant speed that therefore is preferably based on comparison low speed stirs and turns round.
With the explanation constantly of initial input relatively; According to pattern of setting and the initial weight that drops into; The digital display that roughly closes that after husk rice, can access is shown in liquid article display frame 77, and if desired, the user can drop into brown rice more husk rice basket 5, perhaps take out brown rice from husk rice basket 5.But, according to the amount that drops into, may not with 1 ~ 5 each to close number consistent, close number with this each and exist the situation of how many deviations quite a few.In based on rice mill of the present invention, the closing number after the husk rice closes several 20% at each and can carry out husk rice with interior situation, and situation is in addition removed rice or dropped into the demonstration of the attention of rice at liquid crystal display picture 77 display alarms.
Other embodiment as the husk rice action also can constitute and not limit the essence amount of smashing (closing number), and do not have the quantity of the interim ground person of coming into operation hobby.In this case; When the husk rice lower limit amount (be in this example 1 close) of the not enough rice mills of number is closed in the processing that drops into or surpass husk rice upper limit amount (be in this example 5 close), send the NG warning; At the odd number that closes that contains in addition; For example drop under 2.5 situation of closing; With 2 close, 3 operation modes that close or with 2 close, 3 operation modes that close are that the operating condition that benchmark is adjusted carries out the husk rice action, drop under 4.7 situation of closing, with 4 close, 5 patterns of closing or with 4 close, 5 patterns of closing are that the operating condition that benchmark is adjusted carries out the husk rice action; Can carry out programming through weight measurement midway whereby, so that append the husk rice rate of husk rice up to regulation.If note so constantly not carrying out excessive husk rice, then can not have stage ground actual quantity is carried out husk rice up to measuring.The amount of the cereal that need not like this in the pearling mill that is intended to batch type (promptly drop into cereal in the lump and grind paddy mode), to drop into, and can access desirable rice, divide and husk rice with a pestle and mortar or plumule rice etc.
In addition; With rice is example; Jigger is generally and uses a flat cup of cup upper end partly to be 180ml (1 closes=about 150g) as 200ml (about 165g), scale to greatest extent; Close (about 150g) rice needed 1 and close brown rice for obtaining 1 of husk rice rate about 91%, can realize through dropping into a flat cup (about 165g).In addition, because of existing a little error, change, the user forms 1 input amount of closing about 160g.In addition, if other cereals are then determined with its weight with the corresponding light-duty cup of its kind substantially.As stated; In advance the husk rice operation of regulation is carried out programming; This husk rice before the stipulated time that finishes temporarily stops husk rice and gravimetry midway; And then calculate the husk rice rate of this moment, poor according to the husk rice rate of the husk rice rate that calculates from this moment weight and target calculated the needed husk rice time afterwards.Perhaps, also can form, confirm to be used to form the needed husk rice time of husk rice rate of target and it is stored in memory 84 to each husk rice rate in advance, obtain the husk rice time that needs from this memory.Carry out husk rice once more with this husk rice time then, can have the husk rice of the desired husk rice rate of user thus.
Like this,, suitable husk rice rate can be accessed, colory husk rice, rice washing can be formed according to quality, hardness, the humidity of rice, can corresponding interpersonal slightly different mouthfeel.
In addition, the load that when husk rice, applies to the rotation stirring body changes according to the carrying out of husk rice.Keep watch on rotary speed directly or indirectly if use; And control rice mill rotary speed, so-called feedback system according to this result; Though can realize the desirable rotary speed confirmed; But when not carrying out FEEDBACK CONTROL, be stripped from and load lightens the situation that also exists rotary speed to increase along with chaff.In the present invention, do not limit especially,,, all should be interpreted as in the scope that belongs to technology of the present invention even if produce the rice mill of the change of rotating speed betwixt so long as can get final product according to the passage reduction rotating speed of time, the rice mill that stops halfway.
Be illustrated though above-mentioned embodiment is example with the rice mill, so long as the pearling device of stirring-type, just can under the constant state of the function of keeping essence, make the improvement that is fit to this product and use.Therefore, the present invention is not limited to above-mentioned embodiment, also is not limited to its title.And the rotary speed of mixing part, rotational time can suitably change in the scope that does not break away from purport of the present invention.For example; When being example with table 2 and table 3; Also can be set at the husk rice time that prolongs second stage slightly, correspondingly shorten purpose husk rice time phase III, perhaps be set at the rotary speed that improves second stage slightly and shorten its time; And prolong the time of phase III, can among each speed is divided, finely tune thus the husk rice time.In addition, the rotary speed in any stage at least of also can slowing down and correspondingly prolong the husk rice time prolongs the total time that finishes up to husk rice slightly, can the effect that obtain not affected greatly.In addition, husk rice is carried out in also can Assembly Phase property successively decrease with successively decreasing of curve.In addition, should be careful the value of each husk rice rate and the relation between the pattern, except illustration and be in the scope of patent request by the situation of regulation particularly, do not limit especially.
Then, use the flow chart of Figure 10 A, Figure 10 B to come the control example that is used to carry out husk rice is explained particularly.
[based on the initialize routine of the husk rice of microcomputer]
(handling 1)
When attaching plug is inserted outlet, the power connection of rice mill 1, microcomputer 81 is carried out initialize routine (SA01).In this initialize routine, microcomputer 81 is obtained the output signal of measuring mechanism's 100 outputs from load transducer, and measures its load.Then, judge whether this determined load is consistent with the load of bearing from the husk rice basket 5 that is mounted.In this example, the load that applies to load transducer mensuration mechanism 100 from husk rice basket 5 is the weight of husk rice basket 5 and the weight of rotation stirring body 9.The weight of this husk rice basket 5 is set up (storage) memory in rice mill 1 in advance with the weight of rotation stirring body 9 in the stage of dispatching from the factory.The weight of 81 pairs of husk rice baskets 5 of microcomputer compares with the total weight of the weight of rotation stirring body 9 and the load of being measured by load transducer mensuration mechanism 100.Then, under the situation of difference in the allowed band of regulation of load, judge husk rice basket 5 and rotation stirring body 9 are installed.On the other hand; In the difference of load not under the situation in allowed band; Microcomputer 81 judge in husk rice baskets 5 or the rotation stirring body 9 any or this both correctly installed, and be shown in display frame 77, the prompting user correctly installs husk rice basket 5 and rotation stirring body 9.
Husk rice basket 5 and rotation stirring body 9 also can form can be replaced by different types of product according to purpose and use.Have according to its kind under the situation of Different Weight, the husk rice basket with each kind is set in rice mill 1 with the weight of rotating stirring body in advance.Thus, can be in this initialize routine, the weight of relatively setting and the load of mensuration, any husk rice basket and rotation stirring body have been installed in identification automatically.In addition, in this example, though with the object of Mi Zuowei pearling and as example, use " husk rice basket " such term to describe, as the beginning explanation of present specification, husk rice is not limited to rice, can be different types of cereal etc.Therefore; Be not limited to " rice mill ", " husk rice basket " such term; Can replace with the term of " rice mill " " husk rice basket " that the general widely cereal etc. beyond the rice can utilize; If read the application's disclosure, those skilled in the art can easily understand foregoing.
Get back to example, in initialize routine, can automatically discern judgement that whether husk rice basket 5 and rotation stirring body 9 are installed, among the husk rice basket of a plurality of kinds and rotation stirring body, any husk rice basket and rotation stirring body are installed the Mi Jinhang pearling.According to the kind of husk rice basket with the rotation stirring body, for example, there are condition of different in the time and the rotary speed (" husk rice motion profile (profile) " (extensively being commonly referred to as " pearling motion profile ")) that are turned round by table 2, the husk rice of table 3 explanation.Therefore; Also can form; The storage of in advance that the husk rice basket is corresponding with the kind of rotation stirring body husk rice motion profile according to the weight of the husk rice basket of automatically measuring with the rotation stirring body, is confirmed the kind of husk rice basket and rotation stirring body in memory; And access and be somebody's turn to do husk rice basket of confirming and the data of rotating the corresponding husk rice motion profile of stirring body, thereby according to the husk rice of this profile.
In addition; In this example; Should measure the weight that mechanism 100 applies to load transducer and form husk rice basket 5 and rotation stirring body 9, but in addition miscellaneous part is also under the situation of imposed load when installing, the weight of these parts is also further sued for peace certainly.
In addition; Microcomputer 81 also can be judged as husk rice basket 5 and rotation stirring body 9 have been installed after; Make the motor rotation till reaching a certain constant rotary speed, measure output, check whether its output waveform has change from the rotary encoder of the rotating shaft that is installed on this motor.Promptly; This be because husk rice basket 5, rotation stirring body 9 correctly be not installed on the situation in the chaff box among the rice mill 1 or situation that the rotation of motor is counteracted under; Therefore load makes the rotation of motor become irregular rotating change midway, produces change in the output from the rotary encoder of the rotation of measuring motor.If output waveform display abnormality from encoder; Judge that then husk rice basket 5, rotation stirring body 9 are correctly installed, microcomputer 81 sends the prompting user and the message of husk rice basket 5, rotation stirring body 9 correctly is installed or shows in display frame 77 afterwards.
When microcomputer 81 is judged as when husk rice basket 5 correctly is installed with rotation stirring body 9, load is set at zero, and processing is moved to the operation (SA02) that the startup picture that carries out husk rice is shown.
(replacing handling 2)
Can carry out programming to rice mill 1, replace above-mentioned processing 1 so that carry out following replacement processing 2.
Replace handling 2 is that not measure husk rice basket 5 be the processing of prerequisite so that the husk rice basket of having confirmed in advance 5 correctly to be installed with rotation stirring body 9 with the load of rotation stirring body 9.Be assumed to the state that does not drop into any article, and load is set at zero to the husk rice basket.This processing 2 at random has been used for the replacement of initial setting rice mill by the user; The information of having carried out this replacement in expression is stored under the situation of rice mill 1; Microcomputer 81 is carried out and is replaced processing 2 to replace handling 1; Can get into the action of rice mill immediately, thus the raising of user convenience property.
When showing to the startup picture (SA02) that carries out husk rice in display frame 77 when replace handling 2 load measured and be set at zero (promptly being set at the state that fully drops into rice) and finish initialization.
Operation SA03 ~ SA04 and SA06 represent to accept the processing of user's action.Operation SA03 is the action of opening lid and among husk rice basket 5, dropping into rice, and operation SA04 is the user carries out the selection of desirable husk rice pattern through guidance panel 70 action.SA06 is the action of putting into rice to husk rice basket 5.
At first; When opening when covering; The gauge tap that is arranged at the main body of rice mill 1 for CD-ROM drive motor cuts out, though form the safe condition of the rotation that suppresses motor, inserts under the state of outlet at the attaching plug of rice mill 1 main body; When rice mill 1 energising, rice mill 1 can be carried out the action of microcomputer constantly.The above-mentioned gauge tap that is used for CD-ROM drive motor can be made up of microswitch.Then; Because rice mill 1 can calculate the weight of the rice of putting into husk rice basket 5 in real time; Therefore measure the amount of the rice of putting into husk rice basket 5; And calculate the amount (amount of so-called husked rice) of the rice after the husk rice according to the husk rice rate of the pattern of selecting with respect to the user and the amount of the rice of input, the amount of the husked rice that begins will to calculate in real time is shown in the action (SA05) of display frame 77.
But, surpassing in the amount of the rice of putting into husk rice basket 5 under (processing in this example close number surpass 5 close) situation of amount that rice mill 1 can husk rice, microcomputer 81 carries out mistake demonstration (SA09) in display frame.The user removes the rice of putting into husk rice basket 5 while observing this picture demonstration, thereby can reduce the amount (SA06) of rice.
On the other hand, be less than at the rice of putting into husk rice basket 5 under (processing is in this example closed several less thaies 1 and closed) situation of the amount that rice mill 1 can husk rice, carry out mistake in display frame and show, notify that the user increases input meter amount (SA10).The user drops into rice while observing this picture demonstration to husk rice basket 5, thereby can increase the amount (SA06) of rice.
Like this; Adjustment is to the amount (SA06) of the rice of husk rice basket 5 inputs; When the amount of the rice of putting into husk rice basket 5 forms the scope of the amount that rice mill 1 can handle (amount after the processing is 1 to close ~ 5 close in this example) (SA07 " OK "); Show the amount (SA05) of the husked rice that the amount by the husk rice rate of the pattern of selecting with respect to the user and the rice of input calculates in display frame 77, so the user can be on one side at length hold the amount of closing number, adjustment on one side meter that forms which kind of degree with respect to the husk rice pattern in the input stage of rice.In addition, can show the amount of husked rice with weight, also can replace weight to show the amounts of husked rice, close relation between several weight and the general jigger as above-mentioned with respect to 1 with corresponding with this weight number that closes in display frame 77.In addition, show the amount of husked rice though consider user convenience property, also can show the measured quantity of the rice of the actual input of (that is, before the husk rice) before processing.Perhaps, also can be simultaneously or alternately show the husked rice that calculates amount, with the measured quantity of actual rice.
In addition, though use the starting stage need not carry out,, therefore also can press replacement button 76 before and carry out 0g and calibrate carrying out the husk rice running because mixing part, husk rice basket be according to the frequency of utilization abrasion of wear out at body.
When closing loam cake 3, open the gauge tap (SA08) that is used for the motor driving, shown in Figure 10 B, can get into husk rice running based on user's indication.When the user operates and opens beginning/stop button 75 to guidance panel 70 (SB01); Be shown as " in the husk rice " (SB02) in display frame 77; The operating condition (SB03) that decision is represented with the corresponding husk rice motion profile of husk rice pattern and husk rice amount, and begin husk rice turn round (SB04) based on the operating condition of this decision.
As above state bright that kind; Rice mill 1 is controlled the rotation of motor according to the amount (weight) of the rice that drops into and the pattern of setting; And carry out the constant speed stirring running of constant rotary speed, can carry out the stirring of successively decreasing (rotation of the successively decreasing) running that changes to lower rotary speed from than higher rotation.And the stirring of successively decreasing (rotation of successively decreasing) running can be to rotate the running of successively decreasing that continues that running, rotary speed curve property or linearity change by the successively decreasing of stage that a plurality of rotary speeies constitute, and then can be the running of their plyability of combination.The operating condition of these a plurality of kinds is determined according to husk rice amount and husk rice pattern.
In addition; As above state bright that kind; When beginning husk rice when action (SB04),, temporarily stop motor (SB05) and measure husk rice weight and try to achieve current husk rice degree (husk rice rate) (SB08) in order to form the milling degree corresponding (husk rice rate) and to prevent too much husk rice with the pattern of setting; Calculate the needed husk rice time of residue, and carry out the husk rice running (SB10) of needs.Determine the concrete example of the processing of husk rice operating condition to describe with reference to table 2 and table 3 pair in the operation SB03 that is used for carrying out such husk rice running being used to of carrying out.
But the mensuration of husk rice rate is the time profile of the husk rice running carried out after being used to predict, in order to realize this purpose as far as possible, need when calculate the husk rice rate or stop several times that motor calculates the husk rice rate, and those skilled in the art can freely determine.
Therefore, decision then is shown utilizes " rice pattern " that 5 brown rice that close are carried out the processing example of the operating condition of husk rice, this example is to be used to the illustration of explaining that the application invents, is the illustration that limits the application's invention and should not be construed as.
Table 2 illustrate be used in to 5 close the stage of carrying out husk rice the stirring rotary speed change and carry out the example of basic husk rice motion profile of the husk rice operation of husk rice.
Here; In " boiling brown rice soon " pattern, " FRESH " pattern, " rice ~ clean rice " pattern, " smashing in 3 minutes " pattern and " smashing in 5 minutes " pattern; Only stir the running of carrying out husk rice, be that so-called constant speed stirs running with the constant speed of a speed; In " smashing in 7 minutes " pattern, stir running based on successively decreasing of two speed, in " rice " pattern, " first-class rice " pattern and " plumule " pattern; Stir running based on successively decreasing of three speed, " brown rice ~ clean rice " pattern is based on successively decreasing of four speed and stirs running in addition.
The husk rice motion profile of " rice " pattern (stirring running based on successively decreasing of three speed) comprising: the running of the running three phases of the running of the running of " 2550 rev/mins, 45 seconds " in initial stage (i.e. first speed), " 2350 rev/mins, 90 seconds " of ensuing second stage (being second speed) and last phase III (being third speed) " 2100 rev/mins, 30 seconds ".The last phase III (third speed) is based on the husk rice of the short time of slow rotary speed, be stripping rice, not equal to be that the effect of mill rice is stronger.Therefore, the mensuration of husk rice rate is not carried out in third speed, and carries out in the running of second speed midway.Though when stop, being about to that temporary transient husk rice stop correct time being made as when is arbitrarily midway in the running of second speed; But form in this example, through before 60 seconds of 90 seconds durations of runs of second speed of representing by the husk rice motion profile, promptly measure after 30 seconds in the running of beginning second speed.Wherein, this value of 30 seconds is according to repeatedly husk rice test in advance, is carrying out under the situation of husk rice according to the husk rice motion profile, obtains according to the result who on average forms 92.5% milling degree behind 30 seconds of second speed.Utilization is based on the quality of the rice between production correct time of this meter, kind, storage life etc., and then utilizes characteristic, the husk rice basket of this rice mill, the shape of rotation stirring body to influence milling degree, can not guarantee that therefore milling degree forms 92.5% after 30 seconds.
If beginning husk rice running (SB04), the mensuration result (SB08) of the husk rice rate of the running from second speed begins 30 seconds after, carrying out is shown as under 92.5% the situation, can think to according to basic husk rice motion profile and by husk rice.Therefore, remaining husk rice running is according to basic husk rice motion profile, and 2350 rev/mins of second speed are carried out remaining 60 seconds (=90 seconds-30 seconds), and then with 2100 rev/mins of husk rices runnings (SB10) of carrying out 30 seconds of third speed.
More manying than 92.5% of prior expectation under the situation of husk rice, for example, is that the expression husk rice makes progress soon than expecting under 92% the situation in the husk rice rate of measuring.Therefore, with 60 seconds remaining husk rice time (=90 seconds-30 seconds) the little husk rice time that the remaining husk rice time ratio of second speed is represented by basic husk rice motion profile, for example carried out in 40 seconds.In addition, be that the expression husk rice makes progress sooner under 91.5% the situation when measuring the husk rice rate.Therefore, with 60 seconds remaining husk rice time (=90 seconds-30 seconds) the littler husk rice time that the remaining husk rice time ratio of second speed is represented by basic husk rice motion profile, for example carried out in 20 seconds.
Reached in the husk rice rate of measuring under the situation of husk rice rate 91% of rice of target, no longer carried out husk rice, and get into the third speed running of basic husk rice motion profile with second speed.As stated, even carry out a little husk rice,, therefore can infer still that according to the operating condition of the third speed of basic husk rice motion profile the husk rice rate is in allowed band because the effect of mill rice is stronger with this third speed.
On the other hand; The husk rice rate of measuring be than the husk rice rate of the rice of target 91% little 90.5%, too much carried out under the situation of husk rice; The time that shortens the husk rice running under the third speed is made it less than 30; For example, shorten 10 seconds, the husk rice under the third speed was made as 20 seconds the duration of runs.Like this, also can be adjusted at the time of the husk rice running of next stage, form the husk rice rate of allowed band.
That kind as described above is adjusted time of remaining husk rice running according to the difference of the husk rice degree of measuring, and can absorb the difference of the different husk rice degree that caused of characteristic of the brown rice of husk rice object thus, thereby carry out more high-precision husk rice.
In the husk rice running that constitutes by two speed or two stages more than the speed; Mainly carry out the time adjustment in second speed; According to circumstances different, in the brown rice that constitutes by four speed ~ clean rice pattern be equally in the running in the stage third speed or third speed after the time of carrying out adjust." brown rice ~ clean rice " pattern is that brown rice is formed rice and then forms the pattern of the clean rice of the state that need not water rice washing and can directly cook.The 4th speed (2100 rev/mins, 300 seconds) is same with third speed (2100 rev/mins, 30 seconds); Be stripping rice, therefore undertaken by the second speed that is adjusted at of husk rice time that difference produced of the husk rice rate of the husk rice rate of basic mensuration and target not equal to be that the effect of mill rice is stronger.
Smash under the pattern 7 minutes of table 2, the adjustment situation that second speed is used in the husk rice time is also identical with the rice pattern.Smash in the pattern at 7 minutes, form first speed and be 2250 rev/mins and turn round 60 seconds, second speed and be 2100 rev/mins and the operating condition that turned round 60 seconds, all compare long husk rice.Therefore; The running that is determined at second speed of milling degree is carried out midway; Though preferably in the second speed adjustment duration of runs of remainder, also can when the switching of first speed and second speed, measure according to the result of this mensuration, perhaps also can midway measuring in first speed.
On the other hand; In based on the husk rice running that a speed is only arranged; Carry out the mensuration of husk rice rate in the husk rice times prior of having passed through a speed of confirming by the husk rice motion profile of the basic husk rice condition of expression; Try to achieve the time of turning round, and carry out the husk rice running of this time of trying to achieve with a speed from remaining husk rice this moment.
How that kind as described above, though mainly carry out the time adjustment in first speed or second speed, carries out mensuration and the adjustment of husk rice time here, just can at random determine as long as can access the milling degree of target.That is, when or at which speed stage to stop motor or stop several times motor measuring, can freely determine according to required all time of precision, the husk rice of husk rice rate and environment of husk rice etc.
In addition, predict the time of the remaining husk rice running of the husk rice rate that reaches target or its allowed band for how according to the difference of the husk rice rate of measuring, also can from several different methods, select.For example consider to have various Forecasting Methodologies such as use that based on the data of the husk rice degree that obtains by several times husk rice running artificial intelligence or anticipation function etc. are predicted.And in this example, though the milling degree of the rice under the rice pattern is set at 91% as the husk rice rate, this numerical value only is illustration, and is not limited thereto, and as above states bright that kind.
The husk rice motion profile of the husk rice operation shown in the table 3 is the husk rice running that rotating speed slows down continuously.Adjust in the mensuration of husk rice rate with according to the result of this mensuration the remaining husk rice time aspect basic identical with the situation of explanation in the reducing of table 2 interimly.But; Result according to the husk rice rate of measuring; Under the situation of remaining husk rice operating time ratio by weak point or the length of the duration of runs shown in the basic husk rice motion profile, for example, residue has residue 60 seconds in basic husk rice motion profile; But the mensuration through the husk rice rate shortens under 40 seconds the situation, needs decision which rotating speed to begin motor from.As the preferred example of the method for such decision, also can try to achieve moment after 60 seconds and recall the rotating speed of 40 seconds motor according to basic husk rice motion profile, carry out the husk rice according to the continuous decay rotation of husk rice motion profile in 40 seconds according to this rotating speed.In addition, in table 2, table 3, " boiling brown rice soon " is as shown in table 1, and when its husk rice rate was 99.6%, stripping rice amount was considerably less, and, the husk rice time also weak point be 30 seconds.In addition, because " FRESH " is used for lapped face immediately, so target is different slightly with other husk rices.Therefore, in " boiling brown rice soon ", " FRESH " pattern, can be set at the mensuration of not carrying out pearling husk rice rate midway.In addition, husk rice pattern is in addition also considered the situation of husk rice that need be urgent etc., according to user's wish, also can be set at the mensuration of not carrying out pearling husk rice rate midway.
Basic husk rice motion profile is such shown in the table 1～table 10 of TOHKEMY 2011-062701 communique, prepares to have the number that closes of 1,2,3,4,5 graduation of whole numbers of units.On the other hand, the amount that rice mill 1 can husk rice is not limited to each integer and closes, so long as between can the MIN/MAX of husk rice (be in this example 1 close ~ 5 close between), also can be to measure arbitrarily.Being used for the husk rice amount of centre is carried out the husk rice operating condition that husk rice is handled, is benchmark and being determined with the husk rice motion profile that respectively closes of integer.One example of the method for its decision below is shown.
At first, measure the weight of the rice that drops into to the husk rice basket.Calculate the corresponding number that closes according to this weight then.In the application's example, be made as and 1 close=about 150g and calculating.Then, two at the end of the amount of this calculating is rounded up and form the husk rice amount.For example, if the weight of the rice of measuring is 651g, then the measured quantity of rice is 4.34 to close, and its two at end is rounded up, and the husk rice amount is 4.3 to close.In addition, when the measured quantity of rice is 4.67 fashionable, be 4.7 to close to two the husk rice amounts that round up in end.
Then; To one at the end of husk rice amount round up and form benchmark close number (below; Be called " elementary sum number "), husk rice operating condition that will be corresponding with this elementary sum number is as the husk rice operating condition of benchmark (below be called " basic husk rice operating condition ").For example, when the husk rice amount is 4.3 fashionable, because the number that closes that its at end is rounded up is 4 to close, so 4 be combined into the elementary sum number, confirms basic husk rice operating condition based on the husk rice motion profile corresponding with this elementary sum number.On the other hand, when the husk rice amount was 4.73, its at end is rounded up and tries to achieve the elementary sum number was 5 to close, and confirmed basic husk rice operating condition based on this 5 husk rice motion profile of closing.
In addition, among this basic husk rice operating condition, close number according to husk rice and shorten with the differences of elementary sum number or be increased in the Halfway Stopping motor and measure time of husk rice rate.
For example, when being example with table 2, when the husk rice amount is 4.7 fashionable, with the 5 husk rice motion profiles that close as basic husk rice motion profile (stirring running) based on successively decreasing of three speed.Then; The situation of the husk rice running of 5 " rice " patterns of closing is as above stated bright that kind; Passing through before second speed of being represented by the husk rice motion profile backhauls 60 seconds of 90 seconds commentaries on classics time; Be about to after temporary transient husk rice stops correct time and be made as 30 seconds, the weight that temporarily stops motor after 30 seconds and measure meter in the running of beginning second speed, thus try to achieve the husk rice rate.On the other hand, closing under the situation of the less slightly 4.7 husk rice amounts of closing than 5, owing to expect that husk rice makes fast progress, therefore for example temporary transient husk rice running is being stopped that reducing 10 second from 30 seconds correct time and after forming 20 seconds.Then, the time after the running from second speed begins 20 seconds stops motor and tries to achieve the husk rice rate.
Below be illustrated in 3 and be combined into husk rice amount (A) and temporary transient running under the rice pattern of elementary sum when counting the stop correct time example (A:B) of (B) with second speed.
A (3.0 close): B (30 seconds), A (2.9 close): B (25 seconds), A (2.8 close): B (25 seconds), A (2.7 close): B (20 seconds), A (2.6 close): B (20 seconds), A (2.5 close): B (20 seconds), A (3.1 close): B (35 seconds), A (3.2 close): B (40 seconds), A (3.3 close): B (45 seconds), A (3.4 close): B (45 seconds)
As above, it is that benchmark is adjusted about about 5 seconds ~ 15 seconds with basic husk rice operating condition that temporary transient husk rice stops correct time.
Can expect with the husk rice amount correspondingly the progress degree of the husk rice in other progresses change.Therefore, if decide the condition of remaining husk rice running, then can access more high-precision husk rice according to this husk rice rate of trying to achieve and the amount of rice.The condition of remaining husk rice running can use various Forecasting Methodologies and situation about determining as stated.With the husk rice condition that becomes benchmark, be that the data of the basic husk rice operating condition represented of the basic husk rice motion profile of each elementary sum number and the data of this basic husk rice operating condition are the basis; The condition of making an appointment the husk rice running corresponding according to 0.1 unit of being combined into the husk rice amount, and be stored in the memory of rice mill 1.Therefore, when beginning husk rice action, try to achieve the husk rice amount, the corresponding therewith husk rice time is read from memory according to the weight of the rice of measuring, thus the whole operating condition of decision husk rice running.In addition, can at random select to increase and decrease the husk rice time in which stage according to the husk rice amount.In addition, its variable value also is not limited to the application's example, for example, also can with the difference of this husk rice amount and elementary sum number proportional and the increase and decrease husk rice time.
So; Decide the temporary transient husk rice running that is used to try to achieve the husk rice rate to stop correct time according to basic husk rice motion profile; Come the temporary transient husk rice running of further adjustment to stop correct time according to the difference of elementary sum number and husk rice amount, thereby decision is with respect to the husk rice condition of husk rice amount.
Get back to the explanation of the action flow chart of Figure 10 B, in order to measure the husk rice rate, the husk rice operation condition that determines based on above-mentioned explanation begins action (SB04), stops motor (SB05) in the time that is determined.Here, for the rotation of motor, combine with the last connector 19 that is installed on husk rice basket 5 through the lower connector 20 that will be installed on driving shaft, and can make the revolving force of motor be delivered to husk rice basket 5 (with reference to Fig. 8).In operation process; Because rotation stirring body 9 rotation at a high speed; Therefore when motor is implemented to stop, the state that utilizes the inertia that rotatablely moves of rotation stirring body 9 that lower connector 20 and last connector 19 are in to stagger, or upward connector 19 become the state that jumps onto lower connector 20.When forming such state, the weight of husk rice basket 5 can't correctly be delivered to upside load relay 105 (Fig. 2 A) through cylindrical wall 5k (Fig. 4 B), can not correctly measure the husk rice weight in the husk rice basket 5.
Visible by Fig. 4 B; On in the cylindrical wall 5k of husk rice basket, exposing connector 19 be formed with circle-shapedly a plurality of by vertically extending projection that forms with the face that tilts; In common operation process; Vertically extending the face with the lower connector that is installed on motor drive shaft 20 coincide, but form the transmission revolving force its engagement come off easily.On the other hand, even if become the state that lower connector 20 and the last connector 19 that is installed on husk rice basket 5 stagger or go up the state that connector 19 jumps onto lower connector 20, the face of inclination also can make motor reverse and form normal engagement.That is, when making motor when counter-rotating, the projection of lower connector 20 along the face of this inclination of last the connector 19 and upwards adjacent projection of connector 19 moves, and meshes between the projection of the projection of a side connector with the adjacency of state and the opposing party's connector freely.
Therefore; Suppose that lower connector 20 and the last connector 19 that is installed on husk rice basket 5 form the state that staggers or go up the state that connector 19 jumps onto lower connector 20; As microcomputer 81 when confirming that from the signal of the encoder of the rotation of keeping watch on motor the rotation of motor stops, promptly forming the situation of 0rpm (SB06); Make motor moment return motion (SB07) after about 0.1 second, after projection being formed each other suitable position relation, measure husk rice weight (SB08).
In the stage of the setting of husk rice running, can roughly infer the husk rice weight of the current time of supposition according to the initial weight of rice, present rice.Therefore, microcomputer 81 exists under the situation of bigger difference between the husk rice weight of the husk rice weight of this deduction and mensuration, and it is not reset into correct location status between lower connector 20 and the last connector 19 that its main cause is shown.Therefore, when the error range of the husk rice weight overshoot of inferring when the husk rice weight that is judged as mensuration is above (SB09 be judged as " unusually "), microcomputer 81 makes motor moment ground reverse once more.In addition, in this example,,, can rotate toward the clockwise direction moment, perhaps also can carry out positive and negative spinning movement off and on according to this connector shape each other though carry out the adjustment between the connector through reverse motor.
And then, for above-mentioned steps, in SB09; Husk rice amount measuring is under the situation of " normally "; Mensuration according to milling degree as explanation before decides remaining husk rice condition, under the situation of the further husk rice of needs, begins husk rice running (SB10) once more.In addition, do not obtain to append running under the situation of enough husk rice degree in husk rice mensuration, to realize further husk rice (SB10).On the other hand, when the husk rice degree that is judged as mensuration was in the scope of the milling degree that target can allow, microcomputer 81 was controlled to be, and finishes the husk rice running and shows that in display frame running finishes, and can not begin (SB11) once more.The user opens lid 3 and takes out rice (SB12), and husk rice finishes thus.In addition; As above-mentioned; The prolongation running that finally is determined at second speed of the milling degree under the situation that stirs running of successively decreasing of three speed finishes correct time and carries out; Judging under the situation of milling degree in desired value of measuring, also can after the grinding running that moves to third speed, finish husk rice running (SB11) in the correct time of the running that finishes third speed.
Like this; When the husk rice weight of confirm measuring is according to the husk rice weight of inferring and in the error range of regulation; Microcomputer 81 calculates current husk rice rate according to the husk rice weight of measuring, and decides remaining husk rice operating condition according to the husk rice rate of this calculating and the husk rice rate of target, carries out husk rice according to the husk rice operating condition of this decision and turns round; Carrying out the operation of the mensuration of husk rice weight as required once more repeatedly, can husk rice be the husk rice degree of aimed at precision thus.
[renewal of operating condition attribute]
In this application,, in the husk rice operation, temporarily stop motor, and measure husk rice weight in order to measure the husk rice degree.Therefore, a series of operation of measuring this husk rice weight and carrying out husk rice can access more suitable husk rice running profile thus.
The object of husk rice, for example according to the country of cereals such as kind, cultivation rice, its hardness, character and perishable degree have nothing in common with each other.For example, utilizing hard rice to be difficult to carry out under the situation of husk rice, in order to form the husk rice degree of target, the time that need Duo than the husk rice time of initial setting.Rice mill 1 according to the application; When carrying out a husk rice; Owing to can obtain forming the data of what husk rice degree according to rotating speed, its husk rice time of husk rice; Therefore after under the situation to identical Mi Jinhang husk rice, through effectively utilizing the data that this obtains, can carry out more correctly husk rice.
Rice mill 1 also can form; Store resulting data; Upgrade the husk rice motion profile, carry out new husk rice based on the data of the husk rice motion profile that upgrades, according to new husk rice so that obtain being used for the motor of husk rice rotary speed and its duration of runs, and the husk rice degree between relation data.Then, utilize this data, can carry out more high-precision husk rice.Even memory 84 be the memory that can rewrite and be cut off the electricity supply, memory that content also can not disappear; For example; Comprise semiconductor memories such as flash rom, microcomputer 81 is to this memory stores data that can rewrite, so that can carry out the husk rice running profile of renewal.Then, based on the data of this storage, microcomputer 81 carries out programming, so that can according to the running of the husk rice motion profile that upgrades.
In addition, also can store the husk rice motion profile of its renewal to the rice of each kind at the memory of rice mill 1.Also can be when carrying out husk rice, the kind of the husk rice of storage is shown in display frame 77, carry out input, the selection of the kind of rice via the operating surface board.Then, before carrying out husk rice, read with the corresponding husk rice motion profile of selecting of rice and use data, thereby carry out its husk rice running.In this case; In order to obtain to use data with the husk rice motion profile that suitable precision is carried out husk rice; Also can not carry out the mensuration of husk rice husk rice rate midway; And as common rice mill, according to the husk rice of the husk rice motion profile that upgrades, also can according to user's indicative of settings whether carry out the husk rice rate mensuration, whether do not measure the husk rice rate halfway and carry out husk rice once.In addition, the husk rice of rice mill 1 running profile can be reset with data, and the default data when turning back to initial dispatching from the factory.
