Description

A kind of stir-frying mechanism of automatic cooking apparatus

Technical field

The utility model relates to automatic cooking apparatus field, be in particular a kind of can the automatic turning food materials stir-frying mechanism of automatic cooking apparatus that makes its thermally equivalent or mix.

Background technology

Automatic cooking apparatus substitutes by the mode of machine the culinary art manually realizing vegetable, and in the process of culinary art, a most important step is exactly that the food materials that will stir in pot make its homogeneous heating, the namely action of slice that adopts of existing cook.Cannot be so flexible as Artificial Control by the mode of machine, the effect reaching stirring ingredients in order to machine can be made and make its homogeneous heating or stir.The following two kinds of modes of main employing in prior art:

The first is contained in by food materials in a closed container, and rotary container makes food materials stir in container, and to reach the effect of stirring ingredients, such as Chinese patent application, application number is the technical scheme of 200610029422.7.This mode is simple, and is easy to control, and does not worry that food materials overflow in container.But it is inconvenient that defect is cleaning, when particularly adopting machine to carry out cleaning automatically, difficulty is very large, and inefficiency, is unfavorable for the Automation Design of equipment.

The second structure is the mode adopting Stirring, namely in pot body, a whirligig is inserted, make it stir the food materials in pot in the process of rotating, such as Chinese patent application, application number is the technical schemes such as 201220334768.9 and 201310285252.9.This mode is without the need to adopting closed container, and for most of food materials, this structure easy to clean, efficiency is higher.But in this structure, food materials may transfer to pot external by the centrifugal force that the rotation of rabbling mechanism produces, and cause the spilling of food materials.Or when culinary art flexible lengths food materials, such as logical heart dish etc., food materials are likely wound on rabbling mechanism, make troubles so again to cleaning.Most important defect is, the region that rabbling mechanism can stir, relative to less pot body, can only be stirred the food materials of local, cannot meet stirring of most of food materials in pot.The majority addressing this problem prior art employing is mixer structure or the size increasing rabbling mechanism, as the technical scheme of 201310285252.9.And the complexity that the consequence that mixer structure directly brings is exactly equipment increases greatly, stability declines.After the size of rabbling mechanism increases, will appropriate design for dodging of miscellaneous part, otherwise easily cause the mutual interference between all parts, weaken the effect of miscellaneous part on the contrary.

Utility model content

Technical problem to be solved in the utility model overcomes above-mentioned defect of the prior art, provide a kind of be convenient to clean and there are good food materials to stir-fry the stir-frying mechanism of automatic cooking apparatus of effect.

Based on above-mentioned purpose, the utility model is achieved by the following technical programs.

First this patent to stir-fry control method based on a kind of automatic cooking apparatus, comprises and drives by the rotation of pot body action that in pot, food materials rotate and stir along pot body transverse reciprocating the action that food materials carry out food materials dispersion.The utility model is the same with the second method of prior art, employing be in open pot body, food materials are stirred, what be different from the prior art be the described mode stirred is adopt the method for back and forth stirring food materials.Stir and stir food materials relative to the mode of existing Stirring food materials, there is not the effect of centrifugal force, do not worry that food materials can trickle down the external side of pot, also do not worry the winding problem of special food materials in addition.Topmost difference is that the mode of stirring can realize the stirring of large-area food materials, namely in the process of work, constantly stirs food materials, it is made to divide dispersion, and the rotation of pot body can realize stirring from different directions food materials uniformly, thus make food materials thermally equivalent, realize stir-frying effect.

In the above-mentioned process of back and forth stirring of being rotatably assorted, main realization be food materials are spread out, disperse, make its thermally equivalent, but a lot of food materials need repeatedly to heat, also needing to stir its multiple face for the food materials that particle is larger makes it all can be heated, and prevents local heating excessive.For this reason, this patent also comprises and scrapes along pot body circumference the action that food materials make it be pooled to carry out in the middle part of pot body food materials to collect.By scraping food materials along pot body circumference on pot body edge, the food materials of dispersion can be pooled to again the middle part of pot body, match with above-mentioned action of stirring like this, form " disperse-collect " iterative cycles, food materials are stirred fully, enable further thermally equivalent, prevent local heating excessive.

In order to ensure that culinary art can continuous print operation and food materials in pot can be made to be able to abundant heating, described food materials rotate, food materials dispersion and food materials collect three actions and preferably can carry out simultaneously, and mutually do not interfere.So in automatically controlling, need the action reasonably distributing each action equipment poor, mutually dodge, prevent from mutually colliding between equipment and equipment, thus the continuity of guarantee effect.

Above-mentioned food materials collect action, and body is static and scraper plate circumference that is that extend in pot scrapes food materials specifically by one relative pot.Because pot body self is rotate, so the scraper plate extended internally from pot body edge in pot external side fixed installation one, food materials rotate under the drive of pot body, and scraper plate is static relative to the rotation of pot body, such scraper plate just can realize along the circumferential action scraping food materials of pot body, and food materials rotation and the action that collects would not be interfered and can synchronously carry out.In general the span that described scraper plate extends in pot is no more than 4/5 of pot body radius, and dodge space in order to the action disperseed to food materials provides enough, the span that described scraper plate extends in pot is preferably more than 1/2 of pot body radius.

Above-mentioned food materials discrete motions is radial or be parallel to radial direction reciprocally swinging and stir food materials along pot body specifically by a stirring-head, and the oscillation center of stirring-head reciprocally swinging is positioned at above the middle part of pot body.Stir food materials by the mode of reciprocally swinging, frame for movement realize comparatively simple and control flexibly, job stability is also high.In order to mutually not interfere with other two actions, from pot side to, oscillation center is arranged on directly over the middle part of pot body by this patent.Disperse uniformly to realize food materials, describedly stir food materials action and can not rotate in the lump with the rotation of pot body, rotate so oscillation center can not be arranged on pot body, the object that this patent is arranged like this is the rotation in order to allow relatively-stationary oscillation center can not interfere pot body thereupon.Connected by mixing arm in the structural design realizing the method in addition and drive stirring-head to swing, if oscillation center is arranged in pot body and rotates with pot body, in structural design, mixing arm just cannot dodge the fixing scraper plate of above-mentioned relative pot body rotation, therefore in structural design, oscillation center is arranged on to be conducive to directly in the middle part of pot body above-mentioned three actions at the same time operation time ground mutually dodge.

Need when culinary art to topple over food materials in pot body, described swing arm preferably can dodge toppling over of food materials, so can be equipped with certain dislocation with the feed position of feeding mechanism is preferably select, in addition in order to enable the swing of stirring-head cover region larger in pot, described oscillation center too should not be partial to the side of pot body, so preferred scheme is that described oscillation center does not exceed at bottom of pot body projected position with the region of Guo Ti center left and right 18cm.According to the data that test of many times obtains, the scope with best universality is not exceeding with the region of Guo Ti center left and right 6cm.In this region, not only can be convenient to dodge feeding mechanism, stirring-head also can be made to swing the region of covering mainly at the middle part of pot body, food materials can not be caused to be released outside pot by swing mechanism, have and cook effect preferably.

In order to avoid food materials in pot are released outside pot by stirring-head in the process swung, and be conducive to the motion of dodging scraper plate, the scope of described stirring-head reciprocally swinging is no more than 2/3 of pot body lateral dimension.A cambered surface is formed on the bottom of ordinary majority pot body, and described stirring-head reciprocally swinging also forms an arching trajectory, sees from the side, and the length of this arching trajectory does not exceed 2/3 of bottom of pot body camber line.In general the central angle controlling described stirring-head reciprocally swinging is no more than 120 ° and can meets above-mentioned requirements, and according to the data that test of many times obtains, the scope with best universality is 100 °.In this angular interval, can not only meet when stir-frying food materials and make food materials dispersion as far as possible, to reach the object of thermally equivalent, and food materials can not be caused to overflow, the speed swing, rotated and scrape can design comparatively fast under the prerequisite of mutually not interfering, be conducive to improving cooking efficiency, and the bradypragia and cause food materials to be burnt of can preventing from stir-frying.

Contacting with the inner surface of pot body of high temperature for a long time to prevent stirring-head, rubbing and the infringement to stirring-head brought, described stirring-head is suspended from reciprocally swinging on inner surface of pot body.Such stirring-head does not directly contact with the pot body of high temperature, declines all to some extent, make Material selec-tion aspect have popularity, also extended service life in addition the heat resistance of its manufactured materials, the requirement of wearability.In order to keep the stability swung, described stirring-head also can be designed to be suspended from reciprocally swinging on inner surface of pot body at least partly.

In order to make in food materials cooking process can thermally equivalent further, and imitate and turn over a pot action in manual operation process, existing automatic cooking apparatus majority possesses one and turns over a pot process, as No. 201310321969.4 patents of invention of applicant in this case's application.Food materials in pot are made to have higher speed in order to make to turn in pot process, this patent method is also included in the food materials boosting action of to turn in pot process, to promote towards the pot body direction of motion food materials, because the above-mentioned food materials discrete motions of this boosting action and part overlaps, this boosting action should at least not carried out with food materials discrete motions simultaneously.

The action of described food materials boosting promotes food materials specifically by stirring-head along the unidirectional swing of the pot body direction of motion.Realize boosting action by stirring-head, not only simplify system structure design, mechanism's integrated level is high, and be convenient to control.Be exactly in simple terms in general cooking process, control stirring-head reciprocally swinging, realize the stirring of food materials in pot and stir, when pot body moves forward and carries out turning over pot action, control stirring-head moves with pot body forward and promotes food materials in the same way, gives the acceleration turning over pot with food materials one, is so advantageously turning over provoking in pot process in food materials, preventing portion divides food materials be bonded in pot and cannot realize turning over pot, makes being heated of food materials more even.

According to the attribute of cooked vegetable, comprise the number of food materials, granular size, shape and viscosity etc., the amplitude of the unidirectional swing of stirring-head in the action of described food materials boosting is selected can be different, but in order to give with food materials enough turn over a pot boosting, this amplitude should be greater than 1/10 of food materials discrete motions stirring-head reciprocally swinging amplitude.When turning over pot action and being larger, such as comparatively large for particle and the vegetable needing high temperature to stir-fry fast, in order to give with food materials enough turn over a pot boosting, in the action of above-mentioned food materials boosting, the amplitude of the unidirectional swing of stirring-head preferably exceeds the amplitude boundaries of food materials discrete motions stirring-head reciprocally swinging.In this process because pot body also advances fast simultaneously, even if so this boosting action is greater than the amplitude of discrete motions, does not worry that food materials can be thrown pot external yet, contribute to throwing and stirring of food materials on the contrary, can real simulation manual operation.The amplitude of the unidirectional swing of stirring-head, from a lateral boundaries of stirring-head reciprocally swinging, is accelerated to be rocked to exceed its opposite side border.Such stirring-head can promote food materials as much as possible to greatest extent, and can not hinder throwing of food materials when to turn over pot.Certainly this food materials boosting action neither without any the expansion of restriction, and the amplitude of the unidirectional swing of stirring-head does not exceed 1.6 times of the amplitude of food materials discrete motions stirring-head reciprocally swinging.According to the data that test of many times obtains, best selection is that the central angle of the unidirectional swing of stirring-head is no more than 150 °.In this interval, namely can give and enough with food materials turn over a pot boosting power, also can prevent thrust from crossing senior general's food materials simultaneously and dish out outside pot body.

As mentioned above, stirring-head should realize reciprocally swinging stirring action also will realize the action of unidirectional swing boosting, so in order to simplified design, improve the stability that mechanism runs, reciprocally swinging and the unidirectional swing of the preferred described stirring-head of the utility model have same oscillation center.Two actions adopt same oscillation center, advantage in structural design to adopt same driving bindiny mechanism to realize transmission, the driving bindiny mechanism that two are moved is united two into one, by controlling the difference of the amplitude of fluctuation of stirring-head, angle and dynamics, realize different actions, structural complexity is minimized, and control aspect also simplifies more, improves the stability of operation.

In order to further simplify control, the utility model also makes the position of described oscillation center fix relative to the position of pot body further.What need further illustrate be pot body described above itself is have rotation action, fix so described and do not refer to that oscillation center is fixed on pot body, described hereinly fixedly refer to the fixing of both relative positions, namely in the process of turning over pot, center of rotation realizes advancing with pot body, have a down dip, on choose and the actions such as rollback, see from the side, both positions are relatively-stationary.The benefit of this design is, stirs and stir-fry to realize slitless connection, without the need to as existing be cooked in turn over pot before need rabbling mechanism to be separated with pot body, substantially increase operating efficiency.The mechanism driving stirring-head to swing can be arranged in the side supports of pot body in the lump, mobile with the movement of pot body, but do not rotate with the rotation of pot body, so just can realize that food materials rotate, food materials dispersion and food materials collect three actions and carry out simultaneously, and mutually do not interfere.Therefore, this driving mechanism only need control the swing of stirring-head, and without the need to considering the extra control that pot moves and the alternate position spike brought produces of turning over because of pot body, which simplifies the control of driving mechanism.

Based on above-mentioned principle, the utility model devises a kind of stir-frying mechanism of automatic cooking apparatus, comprise a pot body, drive the rotation assembly of pot body rotation, stir the mixing assembly of food materials along pot body transverse reciprocating and drive the power assembly of rotation assembly and mixing assembly, external being arranged with of pot is rotated for supporting pan body, installs the mounting platform of described rotation assembly, mixing assembly and power assembly.This stir-frying mechanism is for single pot body, if be provided with multiple pots of bodies in automatic cooking apparatus, as No. 201310321969.4 patents of invention of applicant in this case's application, then each pot of body all possesses an independently stir-frying mechanism.As above, described in principle, described rotation assembly drives the rotation of pot body to realize the action that in pot, food materials rotate, and mixing assembly stirs along pot body transverse reciprocating the action that food materials carry out food materials dispersion, thus realizes above-mentioned technique effect.

Specifically, described mixing assembly comprises stirring-head, mixing arm, described mixing arm tilts to extend downward in pot body, front end connects stirring-head, rear end connects power assembly, described power assembly drives mixing arm to take its rear end as oscillation center reciprocally swinging, drives stirring-head radial or be parallel to radial direction reciprocally swinging and stir food materials along pot body.Wobbling action can be passed to described stirring-head by mixing arm by described power assembly, realizes the reciprocally swinging of similar pendular movement, disperses food materials.Because mixing arm is for being obliquely installed, described oscillation center refers to the projection of axis in side direction at place, described mixing arm rear end, is not limited on the concrete position of described mixing arm.Adopt the structure of mixing arm can reduce the interference fed intake to food materials, and it is interval to make stirring-head have larger swing, and controls the size in this interval flexibly, to realize the differentiation discrete motions of different vegetable.As mentioned above in order to avoid food materials in pot are released outside pot by stirring-head in the process swung, the scope of described stirring-head reciprocally swinging is no more than 2/3 of pot body lateral dimension, see from the side, the length of the arching trajectory that stirring-head swings does not exceed 2/3 of bottom of pot body camber line.In general the central angle controlling described stirring-head reciprocally swinging is no more than 120 ° and can meets above-mentioned requirements, and according to the data that test of many times obtains, the scope with best universality is 100 °.

Contacting with the inner surface of pot body of high temperature for a long time to prevent stirring-head, rubbing and the infringement to stirring-head brought, described stirring-head is suspended from reciprocally swinging on inner surface of pot body.Such stirring-head does not directly contact with the pot body of high temperature, declines all to some extent, make Material selec-tion aspect have popularity, also extended service life in addition the heat resistance of its manufactured materials, the requirement of wearability.In order to keep the stability swung, described stirring-head also can be designed to be suspended from reciprocally swinging on inner surface of pot body at least partly.

In order to make food materials in pot have higher speed turning in pot process, above-mentioned stir-frying mechanism all also comprises and drives the unidirectional swing of mixing arm, drives stirring-head to promote the boosting assembly of food materials towards pot body side.Boosting assembly can be a passive type mechanism, only triggers in the process of turning over pot, and the action of such food materials boosting and food materials discrete motions just can not be interfered mutually.Specifically, described boosting assembly and power assembly are by a swinging transmission mechanism drive mixing arm rear end, described swinging transmission mechanism can realize boosting action and be connected with the different driving of discrete motions, so just can realize two kinds of different actions on same mixing arm.

Specifically, described swinging transmission mechanism comprises the connection-peg that side connects mixing arm rear end, is connected to the interior axle on connection-peg opposite side, and is socketed in the axle sleeve on interior axle, is provided with rotating and limiting mechanism and interlock torsion spring between described axle sleeve and connection-peg.Described power assembly drives described axle sleeve, and described boosting assembly drives described interior axle.Like this in general cooking process, power assembly propeller shaft sleeve, axle sleeve drives connection-peg by rotating and limiting mechanism, and connection-peg drives mixing arm and stirring-head to carry out reciprocally swinging again.Turning in pot process, axle in described boosting assembly drives, interior axle drives connection-peg, and connection-peg drives mixing arm and stirring-head to swing towards the pot body direction of motion.The effect of rotating and limiting mechanism and interlock torsion spring makes the reciprocally swinging of stirring-head and unidirectional swing have certain amplitude difference, thus the boosting action enabling boosting assembly realize amplitude to be greater than reciprocally swinging, and can be resetted by interlock torsion spring after boosting.When turning over pot action and being larger, such as comparatively large for particle and the vegetable needing high temperature to stir-fry fast, in order to give with food materials enough turn over a pot boosting, in the action of above-mentioned food materials boosting, the amplitude of the unidirectional swing of stirring-head preferably exceeds the amplitude boundaries of food materials discrete motions stirring-head reciprocally swinging.Boosting assembly drives the amplitude of the unidirectional swing of stirring-head from a lateral boundaries of stirring-head reciprocally swinging, accelerates to be rocked to exceed its opposite side border.Such stirring-head can promote food materials as much as possible to greatest extent, and can not hinder throwing of food materials when to turn over pot.Certainly this food materials boosting action neither without any the expansion of restriction, and the amplitude of the unidirectional swing of stirring-head does not exceed 1.6 times of the amplitude of food materials discrete motions stirring-head reciprocally swinging.According to the data that test of many times obtains, best selection is that the central angle of the unidirectional swing of stirring-head is no more than 150 °.In this interval, namely can give food materials enough turn over a pot boosting power, also can prevent thrust from crossing senior general's food materials simultaneously and dish out outside pot body.

In order to realize the reciprocally swinging of stirring-head, described power assembly drives described axle sleeve, described fork connecting bushing by crank, connecting rod and the fork connected successively.This structure is simple, and component is few, lightweightly can not bring too much burden to turning over pot action, and working stability, controls simple and easy.By this mechanism, power assembly adopts one-way motors to rotate can realize reciprocating action.

As mentioned above, described boosting assembly adopts passive type structure, comprises the boosting mechanism and block mechanism that are separated and arrange, described boosting mechanism is arranged on described mounting platform, block mechanism is arranged in frame, when boosting mechanism move to collide with block mechanism time, boosting mechanism drive mixing arm.The advantage adopting block mechanism collision to trigger the mode of boosting mechanism action is exactly get involved without the need to controlling organization, owing to turning in the process of pot, pot body is driven to advance and accelerates, thus drive boosting mechanism also and then to advance, it is in position suitable to be arranged on by block mechanism, and trigger boosting action time boosting mechanism moves to this position, whole process completes automatically, without the need to intervention that is artificial or controlling organization, decrease control design case.

Specifically, described boosting mechanism comprises the push rod collided with block mechanism, the tooth bar be connected with push rod, the gear coordinated with tooth bar, with the housing supporting tooth bar slip and pinion rotation, described gear driven mixing arm, is also provided with back-moving spring between tooth bar and housing.When block mechanism collision push rod, promote push rod, push rod band carry-over bar, the movement of tooth bar makes to rotate with its meshed gears, thus drives the swing of mixing arm and stirring-head.The duration of collision, determine the displacement of push rod and tooth bar, this distance is transformed into the pendulum angle of stirring-head by gear.After having collided, back-moving spring promotes push rod and resets, and also drives stirring-head to reset simultaneously, completes a boosting action.

Additionally by the position rationally arranging block mechanism, different boosting angles can be realized, the culinary art of vegetable of different nature can be suitable for, improve flexibility and the adaptability of automatic cooking mechanism.For this reason, described block mechanism comprises block and regulates the block governor motion of stop location, and described governor motion comprises electronic screw mandrel adjusting device and electronic ruler specifically.

The concrete structure of above-mentioned boosting assembly provides the selection that arranges boosting action flexibly, according to the attribute of cooked vegetable, comprise the granular size of food materials, shape and viscosity etc., the amplitude of the unidirectional swing of stirring-head in the action of described food materials boosting is selected can be different, but in order to give with food materials enough turn over a pot boosting, this amplitude should be greater than 1/10 of food materials discrete motions stirring-head reciprocally swinging amplitude, and amplitude size can be set by the size of the distance of push rod movement.When turning over pot action and being larger, such as measuring less or the vegetable of thickness, need turn over pot fast prevents burnt, in order to give with food materials enough turn over a pot boosting, in the action of above-mentioned food materials boosting, the amplitude of the unidirectional swing of stirring-head preferably exceeds the amplitude boundaries of food materials discrete motions stirring-head reciprocally swinging, and rotating and limiting mechanism and interlock torsion spring serve effect in this action.In this process because pot body also advances fast simultaneously, even if so this boosting action is greater than the amplitude of discrete motions, does not worry that food materials can be thrown pot external yet, contribute to throwing and stirring of food materials on the contrary, can real simulation manual operation.Certainly this food materials boosting action neither without any the expansion of restriction, and according to the data that test of many times obtains, best selection is that the central angle of the unidirectional swing of stirring-head is no more than 150 °.In this interval, namely can give and enough with food materials turn over a pot boosting power, also can prevent thrust from crossing senior general's food materials simultaneously and dish out outside pot body.

In the above-mentioned process that scrapes of being rotatably assorted, main realization be food materials are spread out, disperse, make its thermally equivalent, but a lot of food materials need repeatedly to heat, also needing to stir its multiple face for the food materials that particle is larger makes it all can be heated, and prevents local heating excessive.For this reason, described stir-frying mechanism also comprises and scrapes food materials along pot body circumference and make it be pooled to scraper plate in the middle part of pot body.By scraping food materials along pot body circumference on pot body edge, the food materials of dispersion can be pooled to again the middle part of pot body, match with above-mentioned action of stirring like this, form " disperse-collect " iterative cycles, food materials are stirred fully, enable further thermally equivalent, prevent local heating excessive.

In order to ensure that culinary art can continuous print operation and food materials in pot can be made to be able to abundant heating, described food materials rotate, food materials dispersion and food materials collect three actions and preferably can carry out simultaneously, and mutually do not interfere.So in automatically controlling, need the action reasonably distributing each action equipment poor, mutually dodge, prevent from mutually colliding between equipment and equipment, thus the continuity of guarantee effect.

Specifically, described scraper plate is fixedly mounted on mounting platform, extends in pot from the edge of pot body.Because pot body self is rotate, so the scraper plate extended internally from pot body edge in pot external side fixed installation one, food materials rotate under the drive of pot body, and scraper plate is static relative to the rotation of pot body, such scraper plate just can realize along the circumferential action scraping food materials of pot body, and food materials rotation and the action that collects would not be interfered and can synchronously carry out.In general the span that described scraper plate extends in pot is no more than 4/5 of pot body radius, and dodge space in order to the action disperseed to food materials provides enough, the span that described scraper plate extends in pot is preferably more than 1/2 of pot body radius.

Preferred scheme is, described scraper plate and pot body are axially angled, and this angle can be selected between 40 ° ~ 80 °.Namely scraper plate is not arranged with pot body plane perpendicular, and in certain angle of inclination, and incline direction preferably carries out sense of rotation inclination when food materials collect towards pot body, can scrape food materials in pot preferably like this.

Another preferred scheme is, described scraper plate progressively departs from Guo Ti center from pot body edge.Namely scraper plate does not point to the center of pot body, and the end of scraper plate departs from the installation end of scraper plate and the connecting line at Guo Ti center gradually, and offset direction is identical with sense of rotation, can scrape food materials in pot preferably equally.

Preferred scheme is that scraper plate possesses above-mentioned two architectural features simultaneously.

Specifically, described rotation assembly comprises the bracing ring rotated for supporting pan body and the rotation transmission mechanism driving the rotation of pot body, bracing ring is arranged on described mounting platform, rotation transmission mechanism comprises the gear ring being connected to the external side of pot and the driving gear coordinated with gear ring, and described power assembly drives described driving gear.

Preferably, in order to prevent in pot soup etc. to enter said mechanism, on described pot body along and bracing ring between be provided with sealing ring.

For making the position of described oscillation center fix relative to the position of pot body, pot body side surface is provided with the mounting platform for installing boosting assembly and power assembly.Concrete described power assembly comprises the spinning motor driving rotation assembly and the stirring motor driving mixing assembly, and described mounting platform has one for installing boosting assembly, spinning motor, stirring motor and mixing assembly mounting bracket.

The utility model can realize food materials in automatic cooking process stirring, gather and turn over the actions such as pot boosting, the culinary art action that real simulation is artificial.Coordinating to stir by the rotation of pot body to make food materials disperse, and circumference scrapes the food materials after can making dispersion and gathers, thus realizes food materials and constantly disperse-gather, and makes food materials obtain thermally equivalent, can not be bonded on the bottom of a pan.This action can also auxiliary dish outlet in addition, and vegetable in pot can all be poured out as far as possible, and can play the effect of auxiliary cleaning when cleaning.Turn over a pot boosting action and improve the efficiency of turning over pot further, make food materials in pot turn in pot process and can, by throwing of trying one's best, make it be heated evenly further.In action and structural design, stir and stir-fry and can realize slitless connection, without the need to as existing be cooked in turn over pot before need rabbling mechanism to be separated with pot body, substantially increase operating efficiency.

In order to pouring into of food materials when dodging charging, the above-mentioned oscillation center o of the present embodiment is in the distance of bottom of pot body projected position and Guo Ti center o ' distance 5cm, selectable distance is 0cm, 3cm, 8cm or 10cm etc. in other embodiments, specifically pours the difference of position into and design according to food materials during charging.External in order to ensure food materials can not to be trickled down pot when pouring food materials into, the middle part that position is arranged on pot body poured into by general feeding mechanism.Control for simplifying in addition, reciprocally swinging the best of described stirring-head adopts symmetrical pendulum structure, food materials are disperseed to enable the reciprocally swinging of stirring-head as far as possible, described oscillation center o is good at bottom of pot body projected position not exceed with the region of o ' left and right, Guo Ti center 18cm, region as shown in d in figure, pours into as long as can dodge food materials in this region.

In order to prevent stirring-head amplitude of fluctuation excessive, food materials are released pot external, the scope of stirring-head reciprocally swinging described in the present embodiment is 2/3 of pot body lateral dimension, and selectable scope can also be 1/4,1/3 or 3/5 of pot body lateral dimension etc. in other embodiments.The lateral dimension of described pot body refers to the arc length of inner surface of pot body side camber line, and the scope of described stirring-head reciprocally swinging refers to the arc length of the camber line that travel track is inswept.In addition for taking into account the dispersion to food materials, make under the swing of stirring-head, food materials can spread out as much as possible, can not shift food materials onto pot again external, and the scope of preferred stirring-head reciprocally swinging is 1/2 of pot body lateral dimension.

Be heated to prevent stirring-head Long Term Contact pot body and friction causes stirring-head to damage, stirring-head described in the present embodiment is suspended from reciprocally swinging on inner surface of pot body.In addition for taking into account the dispersion effect to food materials, stirring-head described in the present embodiment and the bottom of a pan keep the distance of 1 ~ 3mm.In other enforcement, described stirring-head can be suspended from reciprocally swinging on inner surface of pot body at least partly.The structural design of this part contact can ensure the stability of stirring-head reciprocally swinging, and contact portion can adopt exotic material, as metal etc., to improve its durability.

Embodiment of the method 2: the present embodiment is that the basis based on embodiment 1 is improved further, shown in composition graphs 3 and Fig. 4, outside the elemental motion of place's above-described embodiment 1, the present embodiment is also included in the food materials boosting action of to turn in pot process, to promote towards pot body 900 direction of motion food materials, as shown in figure medium square arrow.Be attached on said structure, this food materials boosting action promotes food materials specifically by stirring-head along the unidirectional swing of pot body 900 direction of motion.Have in the automatic cooking apparatus turning over pot function, actions such as can being moved ahead by the acceleration of pot body 900, have a down dip, upwarp, food materials in pot are thrown, as indicated by a dashed arrow in the figure, and catch the food materials fallen, No. 201310321969.4 patents of invention of the visible applicant in this case's application of detailed process, do not repeat them here.Food materials one boosting power in the same way in pot is given in this process by controlling stirring-head, the food materials in pot are more conducive to be thrown, the action simulating slice when manually turning over pot operation of this real process, not only conveniently turn over the realization of pot, and can preventing portion divide food materials to be bonded in can not be tossed in pot.

Because this food materials boosting action is utilize the unidirectional swing of stirring-head to carry out equally, so this action is not at least carried out with food materials discrete motions simultaneously.According to the principle analysis of manually turning over pot, boosting power preferably has a down dip at pot body and to carry out with the moment upwarping transformation, so the opportunity that this boosting Action Selection triggers is also preferably before this time point, therefore the unidirectional swing of described stirring-head can be the direct transformation realization carried out in process carrying out reciprocally swinging at stirring-head.Described unidirectional swing is carried out around oscillation center equally, so the rotation action of pot body can not conflict mutually with the unidirectional swing of this stirring-head, so can select to retain rotation action, as shown in the arrow in Fig. 3 and Fig. 4 in the process of turning over pot.Also can select in other embodiments not carry out rotation in the process of turning over pot.

In order to ensure the effect of turning over pot, in the action of food materials boosting, the amplitude of the unidirectional swing of stirring-head is greater than 1/10 of food materials discrete motions stirring-head reciprocally swinging amplitude.The words (being less than 1/10 of reciprocally swinging amplitude) that the amplitude of unidirectional swing is too little, then boosting strength is too little, cannot improve the effect of turning over pot.According to the character of cooked vegetable, as the number of food materials, granular size, shape and viscosity etc., the size of the amplitude of fluctuation of boosting action can be controlled, this amplitude in various embodiments, can select is controllable variations or fixing, can be such as 1/5,1/4,1/2,3/4 or 4/5 of reciprocally swinging amplitude etc.Even for the vegetable that viscosity is large, in the action of food materials boosting, the amplitude of the unidirectional swing of stirring-head should exceed the amplitude boundaries of food materials discrete motions stirring-head reciprocally swinging, as shown in FIG., the border of the angle beta of unidirectional swing is beyond the right side boundary of the angle [alpha] of reciprocally swinging.In order to prevent in the action of food materials boosting stirring-head firmly too senior general's food materials release outside pot, the amplitude of the unidirectional swing of stirring-head, from a lateral boundaries of stirring-head reciprocally swinging, is accelerated to be rocked to exceed its opposite side border.Such stirring-head can promote food materials as much as possible to greatest extent, and can not hinder throwing of food materials when to turn over pot.Certainly this food materials boosting action neither without any the expansion of restriction, and the amplitude of the unidirectional swing of stirring-head does not exceed 1.6 times of the amplitude of food materials discrete motions stirring-head reciprocally swinging.This also can be 1.2 times, 1 times, 0.9 times or 0.8 times etc. in other embodiments.

Bear food materials dispersion due to stirring-head and food materials stir two functions, and all realized by the swing of stirring-head, reciprocally swinging is that food materials disperse, and accelerating unidirectional swing is food materials boosting, therefore in order to simplify control, is convenient to the realization in structural design simultaneously.Reciprocally swinging and the unidirectional swing of stirring-head described in the present embodiment preferably have same oscillation center o, and the position of this oscillation center o is fixed relative to the position of pot body.Described fixes as shown in Figure 2 and Figure 4, namely in the process of turning over pot, oscillation center o moves ahead with the acceleration of pot body 900, have a down dip, upwarps, constant with the relative position of pot body 900 on side, does not consider that oscillation center o fixes relative to the position of pot body 900 rotation on depression angle at this.The advantage of this design is that the frame for movement of described oscillation center o only need consider to control the reciprocally swinging of stirring-head and the trigger timing of unidirectional swing and respective amplitude, without the need to the change of consideration because turning over the relative position that pot action brings.

In conjunction with said method principle, the explanation of process of below said structure being worked.

In conjunction with Figure 19 and Figure 20, in automatic cooking apparatus, comprise for four culinary art vegetables pot body 900(for ease of explanation, two pot bodies are only shown) in figure, pot body 900 is arranged on rotation between different station on pot turning arm of body wheel converting mechanism 910, and the rotation process of pot body 900 can in conjunction with No. 201310721163.4 patents of invention of applicant in this case's application.As shown in figure 19, pot body wheel converting mechanism 910 rotates clockwise, and makes pot body 900 carry out rotation between heating station, discharging station, washing station and charging or preheating station.As can be seen from the figure, described pot body wheel converting mechanism 910 drives pot body 900 to rotate around a pivot, and namely described pot body 900 moves between heating station, discharging station, washing station and charging or preheating station along the arc wheel mark that switches tracks.For convenience of explanation, the present embodiment only draws two pot bodies 900 on heating station and discharging station.

Said method and mechanism design when being in heating station mainly for pot body 900, on this station, spinning motor 510 drives driving gear 120, the rotation of driving gear 120 drives the gear ring 110 be engaged with, gear ring 110 is fixedly connected with pot body 900, and the rotation of such gear ring 110 just can drive the rotation of pot body 900.Pot body 900 is supported on bracing ring 601 by packing ring 130, the rotation of pot body 900 relative support circle 601, and rotation drives food materials in pot to rotate, and sealing ring 140 can prevent from corroding internal mechanism between the inflow of the soup juice in pot pot body 900 and bracing ring 601.

Stirring motor 520 is by the cooperation of conical tooth wheels 530, and drive crank 810, connecting rod 820 and fork 830 successively, the cooperation of this three can drive described axle sleeve 730 to carry out back rotation in certain angle α periodically.The periodicity of axle sleeve 730 is carried out back rotation and is passed to interlock torsion spring 740 and is passed to connection-peg 710, connection-peg 710 can drive mixing arm 202 around oscillation center o reciprocally swinging in angle [alpha], thus realize stirring-head 201 and against pot body 900 inner surface reciprocally swinging, to the action that food materials disperse.Described scraper plate 400 is fixedly mounted on bracing ring 601, and it is inner that its end 402 extends to pot body 900, when pot body 900 rotates relative to bracing ring 601 time.Scraper plate 400 can scrape the food materials of dispersion in pot, makes it be pooled to the middle part of pot body 900.

When spinning motor 510 and stirring motor 520 work simultaneously time, by the dispersion repeatedly of the food materials in pot-collect, thus the stirring of food materials in pot can be realized.For the vegetable of heating, this process can stirring ingredients repeatedly, makes it in pot, be able to thermally equivalent, prevents food materials from burning because of the long-time high temperature in local or being bonded on the bottom of a pan.For the vegetable without the need to heating, as salad or cold dish, food materials and dip can be made to stir, various food can be mixed.In addition, on discharging station, pot body 900 turns to or vertical state, and the side of installing scraper plate 400 is the dish delivery side of pot body, as shown in figure 20.Scraper plate 400 plays the effect of dish delivery guiding, and the rotation of pot body 900 is conducive to food materials in pot are poured out as much as possible in conjunction with the reciprocally swinging of stirring-head 201.On washing station, described pot body 900 turns to back-off state, can be cleaned pot body 900 by bottom-up injection water, the swing of described stirring-head 201 and scraper plate 400 scraping along pot body 900 inner surface, be conducive to clearing up a small amount of food materials residual in pot further, and be conducive to greasy dirt in cleaning pot.

When stirring motor 520 does not work, when spinning motor 510 carries out rotating, pot body 900 can be driven to hocket clockwise and rotate counterclockwise, the action of simulation artificial rolling pot, prevents food materials Yin Gaowen and is bonded on the bottom of a pan.This action mainly for the vegetable that can not stir during culinary art, as bean curd etc., easily by the food materials blended.

For part vegetable, in the process of culinary art, be only the object that dispersed with stirring is also not enough to reach homogeneous heating, be not enough to the taste reaching expection in other words.For this reason, when such vegetable of culinary art, cook generally can adopt the action of turning over pot, and this action is conducive to food materials and can be heated fast, reaches necessary requirement to enable its taste.No. 201310321969.4 patents of invention that applicant in this case applies for are exactly mechanically simulate this action, are exactly in simple terms to drive pot body 900 to realize: have a down dip-move ahead-upwarp-step such as rollback.In order in the process upwarped, the food materials in pot more can be conducive to throw, and avoid part food materials to be bonded on the bottom of a pan, do not reach the situation of the object of turning over pot.The utility model adds above-mentioned boosting assembly 300, and its operation principle is as follows:

When carrying out turning over pot, stirring motor 520 quits work, and back-moving spring 315 promotes tooth bar 312 driven gear 313, makes mixing arm 202 be rocked to extreme position on the left of reciprocally swinging, as shown in left-hand broken line in Fig. 7.Time Fan Guo mechanism drives mounting platform 600 and pot body 900 to move ahead, described in the mechanism be arranged on mounting platform 600 slide all thereupon.Boosting mechanism 310 is separated setting with block mechanism 320, boosting mechanism 310 is arranged on platform 602 and moves thereupon, block mechanism 320 is fixedly mounted in frame, and adjusts the position of described block 321, and opportunity push rod 311 being moved to collide with it is moment before pot body 900 upwarps action just in time.The position of block 321 is fixing, and when Fan Guo mechanism continues to drive pot body 900 to move forward time, block 321 can promote the relative housing 314 of push rod 311 pressed home spring 315 and slide.In this sliding process, the slip of tooth bar 312 drives the rotation of the gear 313 be engaged with, thus axle 720 and the one-directional rotation of connection-peg 710 that is connected with interior axle 720 in realizing driving.The rotation of connection-peg 710 drives mixing arm 202 to accelerate to swing towards the direction that pot body 900 advances around described oscillation center o.This just drives stirring-head 201 to against pot body 900 inner surface and promotes food materials fast forward, makes food materials in pot have one instantaneously in the front and back that pot body 900 upwarps along pot body 900 radian speed upwards.During amplitude peak when mixing arm 202 amplitude of fluctuation reaches its reciprocally swinging, push rod 311 continues to be promoted by block 321, then the amplitude of the unidirectional swing of mixing arm 202 exceedes the amplitude peak of its reciprocally swinging, as shown in Figure 4.

In the process of this boosting, the rotation of described connection-peg 710, can be passed to described axle sleeve 730 by interlock torsion spring 740.As mentioned above, axle sleeve 730 is fixedly connected with fork 830, and it has certain rotational limitation, namely in above-mentioned angle [alpha], carrys out back rotation.When the rotation amplitude of connection-peg 710 exceedes this region time, angle beta as shown in Figure 4, connection-peg 710 relatively rotates described for rotation interlock torsion spring 740 with axle sleeve 730, and the limitation that connection-peg 710 can exceed angle [alpha] is rotated further.Such boosting assembly 300 just can drive the amplitude of the unidirectional swing of stirring-head 201 to exceed the amplitude boundaries that power assembly 500 drives stirring-head 201 reciprocally swinging.The position of block 321 is different, and push rod 311 with it collision rift is extruded the distance difference of motion, drives the amplitude of stirring-head 201 boosting just different like this.

When Fan Guo mechanism drive mounting platform 600 and pot body 900 rollback, push rod 311 increases gradually with the distance of block 321, and back-moving spring 315 promotes push rod 311 and resets, tooth bar 312 driven gear 313 backwards rotation, the laggard horizontal reset of stirring-head 201 boosting.The relative backwards rotation of connection-peg 710 and axle sleeve 730, under the pulling force of interlock torsion spring 740, until the relative position that rotating and limiting mechanism 750 limits, connection-peg 710 returns to original state with the relative position of axle sleeve 730.Now, under stirring-head 201 comes back to the control of power assembly 500.

Describe in above-mentioned accompanying drawing position relationship for only for exemplary illustration, the restriction to this patent can not be interpreted as; Obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.All do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., within the protection domain that all should be included in the utility model claim.
