Embodiment one:
Referring to Fig.1 shown in -4, the horizontal making drinks machine that the preferred embodiment of the present invention proposes, including shell 10, accommodating glueThe cup for infusing and steeping 3 of capsule 6, brew head 2, control device 1, water inlet pricker 21, the liquid supplying device for drawing pricker 22, connection water inlet pricker 214, feeding port 101 is arranged in driving element 5, sealing element 7,10 upper surface of shell, and water inlet pricker 21 draws pricker 22, sealing memberThe side of brew head 2 is arranged in part 7, and liquid supplying device 4 is connected by water pipe with water inlet pricker 21, the cup for infusing and steeping 3 and brew head 2It is correspondingly arranged, the cup for infusing and steeping 3 is horizontally movable relative to brew head 2, and the control device 1 includes master control borad 11, master control boradInterior to be equipped with storage unit, memory cell contains identification information, brews program, brewing parameter etc., and control device is controllable to be drivenThe movement of dynamic element 5, thus drive 3 transverse reciprocating of cup for infusing and steeping mobile,
The side of the brew head 2 is additionally provided with optical identifying apparatus 8, and optical identifying apparatus 8 includes identification probe 81 and visitsHead-shield 82, identification probe 81 are arranged in probe cover 82 and are correspondingly arranged with the identification region, and the setting of sealing element 7 is brewingFirst 2 side, sealing element 7 are provided with through-hole, and water inlet pricker 21, extraction pricker 22 and probe cover wear the 82 excessively described through-holes, instituteThe diaphragm 62 that capsule 6 includes capsule ontology 61 and closed capsule ontology is stated, the diaphragm 62 is equipped with multiple identification regions, the knowledgeOther region is printed with micro identification code, and each identification region at least prints a micro identification code.
When work, capsule is placed in base by feeding port 101, and the control device control movement of driving element 5 is to drive punchingBubble cup 3 is mobile to 2 direction of brew head, so that the identification region of diaphragm moves to 8 direction of optical identifying apparatus and is bonded probe cover82, when identification region is bonded with probe cover 82, capsule diaphragm compresses sealing element 7, to prevent in drink preparation processIt leaks.During cup for infusing and steeping moves to optical identifying apparatus 8 and is bonded probe cover 82, the identification region of capsule is graduallyClose to identification probe 81, after the identification region enters identification 81 identification range of probe, identification probe 81 reads identification regionInterior micro identification code, identification probe 81 form the first reading position with identification region.Control device 1 is by the miniature identification of readingCode information is compared with the identification information that the memory cell is stored up, if in identification information including the micro identification codeInformation then call the corresponding program of the identification code, thus according to the information of micro identification code determine capsule type, preparation drinkThe parameters such as pressure, the temperature of product, prepare drink by the way of optimal.If in identification information not including the micro identification codeInformation, then control device control cup for infusing and steeping retract 2 seconds, retract distance be A, A=8mm, cup for infusing and steeping be equipped with punching slurry sliding block 31,Punching slurry sliding block 31 is the convex ribs being arranged on the inside of cup for infusing and steeping, when capsule is arranged in cup for infusing and steeping, capsule side wall and the convex ribs mistakeIt is full of cooperation, then cup for infusing and steeping drives capsule to retract and prevents capsule in fall back process from punching slurry sliding block 31 in fall back processIt falls off, the identification region and optical identifying apparatus separating distance of capsule diaphragm are B, B=3mm, the knowledge of control device control diaphragmOther region is bonded probe cover 82 again again.
During diaphragm is far from probe cover 82, diaphragm by by 82 impaction state of knowledge probe cover to relaxation state, thereforeWhen identification region is bonded probe cover 82 again, diaphragm is optically recognized device compression by relaxation state again, due to pressureTight process is uncertain, such as whether diaphragm occur fold and and fold occurs or curved position is different.Therefore, diaphragmThe position being bonded with the bonding position of optical identifying apparatus with the last time is not quite identical, the especially corresponding identification of identification probeRegion and last identification region are inconsistent, and identification probe and diaphragm at this time forms the second reading position, optical identification dressSet the micro identification code read again on diaphragm.Since the identification region of diaphragm is different from the state that optical identifying apparatus is bonded,Therefore, can be effectively prevented can not identify caused by the reasons such as fit area fold or bending, by secondary identification, greatly improveDiscrimination.
So-called horizontal making drinks machine refers into water pricker 21, draws the laterally setting of pricker 22 and 6 central axis of capsule,And cup for infusing and steeping 3 can move relative to 2 transverse reciprocating of brew head in base and (laterally can be horizontal or level of approximation form),It draws pricker 22 and is located at 21 lower section of water inlet pricker, in order to draw liquid, reduction residual.
It is appreciated that cup for infusing and steeping, which retracts distance A, to be adjusted according to actual needs, for example, 4mm, 5mm, 6mm,7mm,9mm,10mm,11mm,12mm,13mm,14mm,15mm.As long as ensureing that identification region is separated with probe cover, such asFruit is retracted apart from too small, then identification region does not separate with probe cover, therefore when compressing again, identification region and probe cover conformable regionDomain state does not change, still cannot effectively identify.If retracted apart from excessive, capsule may fall off.
It is appreciated that the separating distance B of diaphragm and probe cover can be adjusted according to actual needs, such as 0.5mm,0.7mm、1.0mm、1.1mm、1.2mm、1.3mm、1.4mm、1.5mm、1.6mm、1.8mm、2.0mm、2.2mm、2.4mm、2.6mm,2.8mm,3.2mm,3.4mm,3.6mm,3.8mm,4.0mm,4.5mm,5.0mm.If separating distance is too small, diaphragmDeformation be unable to get abundant release, recognition effect is undesirable, if separating distance is excessive, capsule may fall off.
It is appreciated that retract the time can also with appropriate adjustment, for example, 1s, 1.2s, 1.4s, 1.6,1.8s, 2.2s, 2.4s,2.6s,2.8s,3.0s.If retracting overlong time, drink preparation time is influenced.
The micro identification code is OID code-point, and the structure of OID code-point is as follows:
As shown in Fig. 4-1, identification code image is made of 16 points, and table header 601 is made of 7 points, and data portion 602 is by 9A point composition, each pair of point answer four quadrants, and according to a difference for setting quadrant, each point can indicate 2 data.Rule is such asShown in Fig. 4-2,10 are indicated, in first quartile expression in fourth quadrant expression 00, in third quadrant expression 01, in the second quadrant11, when being encoded using above-mentioned coding rule, 9 points of data portion can characterize 18 and reconstitute data, completely can be withIt meets the requirements, it might even be possible to which more data contents are added in data.
Data include at least master data portion, check portion and preliminary data portion.In the present embodiment, data portion includes 18 altogetherData, master data portion are made of preceding 8 data, are characterized drink preparation condition, 0~255 number can be indicated altogether, according to readingThe corresponding program of data call can prepare 256 kinds of drinks altogether.Intermediate 2 are check code, verify reading preceding 8 data whetherCorrectly.If preceding 8 data checks are correct, preparation procedure is determined according to preceding 8 data.If preceding 8 data check errors,Then drink is prepared according to preliminary data portion data.Due to preceding 8 data characterizations, 256 kinds of drinks, preceding 8 data are continuous, as long as 1 bit-errors in 8 data, data are exactly mistake.
Preliminary data portion is made of 8 data below, and preliminary data part is constituted at 4 groups, every group by 2, i.e., every group by 1A point composition, 4 points, which respectively indicate, to be reconstituted temperature, reconstitutes water, air blowing power and gassing time, reconstitutes major class.Due to eachPoint can indicate 2 data, therefore, in the present embodiment, can characterize 4 kinds and reconstitute temperature, 90 DEG C, 85 DEG C, 80 DEG C, 75 DEG C；4 kinds of punchingsWater diversion volume, 200ml, 180ml, 160ml, 140ml；4 kinds of air blowing power and gassing time length 20 seconds high-power, 20 seconds small functionRate, 10 seconds high-power, 10 seconds small-powers；4 kinds reconstitute major class tea, coffee, soya-bean milk, other.
When identification module transmits data to machine, when 8 data checks are correct before master data portion, machine is called directlyIt is corresponding reconstitute program, current 8 data and 2 (1 point) verifications data collision (i.e. error in data) or data it is correct butWhen in machine without corresponding capsule program, the data call correspondence that machine can reconstitute major class according to 2 (1 point) characterizations reconstitutes major classProgram.When the data for reconstituting major class are also wrong, machine can reconstitute temperature according to remaining 6 (3 points) characterizations and reconstituteThe data calls such as water it is last it is spare it is general reconstitute program, and parameter is reconstituted according to spare reconstitute in program of data point reuse.
It is as follows that parameter corresponds to table, is merely illustrative here, has no effect on the protection scope of the application:
Such as the corresponding binary system of data that reads of identification probe is 0,000 0,010 10 0,101 0101, then master dataThe check code 10 of the data 00000010 in portion verifies correctly, when being equipped with corresponding 0,000 0010 program in drink preparation facilities,It calls corresponding program to carry out preparing drink between then, i.e., carries out drink preparation to prepare the optimal mode of caffe american.
When the data in master data portion are damaged due to image to be identified, for example, the data read are 0000 00**1001010101, due to the data read errors in master data portion, verification failure, then according to the data 0101 in preliminary data portion0101, call corresponding program according to the table in preliminary data portion it is found that calling the program for preparing coffee of default, at this time with 80The water temperature of degree, water supply 180ml, air pump small-power are blown 20 seconds.Accordingly even when which kind of coffee capsule could not recognize is, but still canIt is reconstituted with using more matched capsule coffee program.
The data in preliminary data portion are independent from each other, that is to say, that even if preliminary data portion partial parameters read failure,Still corresponding drink can be prepared with relatively good program.For example, the data read are 0000 00**10 0101**01, due to the check errors in master data portion, carried out preparing drink according to the data in preliminary data portion.Preliminary data portionPartial data can not also be read, and the part that can be read at this time according to preliminary data portion can determine water temperature, quantity and reconstitute major class,Therefore using the program for preparing coffee of default, with 80 degree of water temperature, water supply 180ml prepares drink.
Even if the image thus in the optical device has dirty or damaged, cause to identify the portion in 9 data pointsScore strong point, we remain to extract partial data from identifiable data point, for reconstituting parameter.The video identification codeSet-up mode so that identification it is more accurate, versatility is higher, figure caused by can effectively solving capsule during transportationAs abrasion or dirty caused identification mistake, and prevent the residual liquid in drink preparation facilities from polluting identification caused by capsuleMistake.
The master control borad, which is provided with, brews program, extraction procedures and combination process, and master control borad is selected according to the information of identification codeCorresponding program, water, temperature etc. are selected, to be suitable for the preparation of various drinks.The master control borad is additionally provided with cleaning procedure,When the identification code of reading is empty, cleaning procedure is unlocked, when the identification code of reading is not sky, locks cleaning procedure, thus anti-Only maloperation causes to execute cleaning procedure in drink preparation process.
