Guide rail fixed type automatic pot tossing system
Technical Field
The invention relates to a guide rail fixed type automatic wok tossing system.
Background
The jolt pot is unique to Chinese cooking, cooking materials in the pot can be turned over to uniformly heat different parts of the cooking materials through the jolt pot, so that the cooking quality is improved, and fried dishes have better taste.
The pot-jolting technique is difficult to master and needs a chef to learn and train a lot to understand. In addition, the jolt pan technique has certain requirements on the strength of the arm of the cook.
On the other hand, people have long dreamy to realize automatic cooking of dishes, especially Chinese dishes. The market has emerged with novel kitchen utensils such as electric cookers, microwave ovens, soybean milk machines, etc. However, these new kitchen utensils can only realize simple automatic cooking such as heating, stirring and the like, and are rarely related to the automation of Chinese style cooking with complex process, especially the automation of pot tilting action in the process of cooking.
Chinese patent application 92101587.9 discloses an automatic food cooking apparatus comprising: a base; a fulcrum shaft mounted on the base; a support frame for loading the pan, the support frame being mounted on the fulcrum shaft and including first and second portions extending a distance from each side of the fulcrum shaft; means for mounting the pan to the first portion; and drive means operatively connected to the second section for periodically rapidly accelerating and decelerating the first section to move it between the first and second positions about the pivot axis and to move the pot up and down with the first section and to dump the food in the pot into the air.
The essence of the technical scheme is that the cooker is positioned at the driven end of a lever system, power is applied to the driving end of the lever system to drive the driving end to move up and down, and then the cooker positioned at the driven end moves up and down. The whole system is similar to a children toy 'seesaw'. The disadvantages of this solution are: 1. the cookware is completely positioned at one end of the fulcrum of the lever system, and the distance from the fulcrum to the center of the cookware is greater than the radius of the cookware, so that the whole equipment has larger volume and needs larger arrangement space; 2. the fulcrum of the lever system is fixed, the cookware moves up and down simply, although the pot can be overturned, most cooking materials in the cookware are always concentrated at one end of the cookware far away from the fulcrum, and few cooking materials are distributed at one end of the cookware close to the fulcrum, so that the heat of the pot body is not fully utilized, and further the heat waste and the fuel waste are caused; 3. most cooking materials in the pot are always concentrated at one end of the pot far away from the pivot, so that the moving range of the cooking materials in the pot is small, the cooking materials are not scattered in the pot, and the cooking materials are not uniformly heated in the pot.
Therefore, how to provide an automatic wok tossing device which has a small volume and can uniformly heat cooking materials becomes a problem to be solved in the industry.
Disclosure of Invention
In view of the shortcomings of the prior art, it is an object of the present invention to provide an automatic wok tossing system.
In order to achieve the above object, the present invention provides a guide rail-fixed automatic jolting pot system, which comprises:
a frame;
the curve guide rail is fixed on the rack;
a pan for stir-frying, the pan having a swing axis;
a pot driving device;
wherein, the driving device drives the oscillating shaft of the pan to reciprocate along the curve guide rail, thereby realizing the oscillation of the pan body.
In the present invention, when the oscillating shaft periodically changes on the curved guide rail, it displaces in the vertical direction simultaneously with the displacement in the horizontal direction, and the shape of the curved guide rail is preferably an arc shape with a downward opening.
In the invention, the cooker and the swing shaft form a part of a dynamic lever system, the fulcrum of the dynamic lever system is the swing shaft, and the cooker swings back and forth by taking the swing shaft as the fulcrum.
In the invention, the distance from the fulcrum of the lever system to the central line of the cooker is less than the radius of the cooker; the cooker central line is a line which is vertical to the direction of the lever system and transversely passes through the cooker center.
For convenience of description, one end of the pot close to the pot driving device is called as the rear end of the pot in the specification; the other end opposite to the rear end of the cooker realizes the action of turning the cooker to throw the cooking materials upwards, which is called as the front end. Correspondingly, the direction of the front end of the cooker is front, and the direction of the rear end of the cooker is rear.
The manual pot dragging and jolting action of a chef is continuous periodic movement, wherein each movement period comprises four actions of lifting and pulling. In order to realize the full-text unification, the pot realizes the pot turning action, and the end of the pot which throws up the cooking materials is called as the front end; one end of the pot which is held by a cook is called as a rear end; correspondingly, the direction of the front end of the cooker is front, and the direction of the rear end of the cooker is rear. The four actions of lifting and lifting are the actions of the cook on the pot.
In the initial state, the pot is horizontally arranged on the heating device (or the hearth).
The lifting action is to lift the rear end of the pot, so that the rear end of the pot is slightly higher than the front end, and the materials are gathered at the front end of the pot.
The pulling action is to pull the pot to the back upper part to move the pot to the back upper part by keeping the lifting posture, so that the material is gathered at the front end of the pot, and the pot and the material have a forward stroke space to prepare for sending; meanwhile, the cooking materials which are thrown upwards and fall backwards in the process of lifting and conveying the pot at the previous time fall into the pot again.
The 'sending' action is to keep the posture of the pot unchanged or basically unchanged, to make the front end of the pot point to the front lower part and send the pot to the front lower part; the material moves forward along with the pot, thereby having a forward speed, so that the cooking materials (such as vegetables, meat and the like) in the pot are concentrated at the front end of the pot to prepare for 'lifting'. It is noted that there are at least two factors that concentrate the cooking material in the pot to the front of the pot: firstly, in the 'feeding' link, the posture of the pot is low at the front and high at the back, and the pot slides to the front end due to the inclination; secondly, in the 'sending' link, the pot has a certain forward and downward speed, the cooking materials in the pot also have a certain forward and downward speed (the two speeds can be the same or different), when the 'sending' action is finished and the 'raising' action is prepared, the pot stops moving forward and downward (the front end is prepared to be raised), at the moment, under the action of inertia, the cooking materials in the pot continue to move forward to the front end of the pot, and the concentration at the front end of the pot is realized.
The 'lifting' action is that when the pan is moved to the forefront, the rear end of the pan is pressed by hand to make the front end of the pan suddenly stop and move (lift) to the rear upper part, so that the cooking materials concentrated at the front end of the pan are thrown and turned over along the inner wall of the pan and then fall back to the pan to form a pan turning operation.
In short, the 'lifting' refers to the movement of the front end of the pot from bottom to top, the 'lifting' refers to the movement of the rear end of the pot from bottom to top, the 'pulling' refers to the movement of the pot keeping the front low and the rear high, from the front to the rear, and the 'sending' refers to the movement of the pot keeping the front low and the rear high, from the rear to the front.
In the invention, under the driving action of the cooker driving device, the cooker does periodic motion, and in each motion period, the motion of the cooker can be divided into four links of lifting and lifting so as to simulate the cooker tossing action of a cook. Specifically, in a pot motion cycle, the pot driving device presses down the rear end of the pot (for example, the proximal end of the pot relative to the fulcrum), so that the front end of the pot (for example, the distal end of the pot relative to the fulcrum) is raised correspondingly, and the raising action is realized; then the cooker driving device enables the rear end of the cooker (such as the near end of the cooker relative to the fulcrum) to move upwards to be approximately horizontal or low in front and high in back, thereby realizing the lifting action; the pot is then moved from front to back ("pulled") and then from back to front ("sent") by the pot drive. Through the 'sending' action, the front end of the pot is sunk and moves forwards and downwards, so that cooking materials (such as vegetables, meat and the like) in the pot are concentrated at the front end of the pot; by raising the front end of the pot, the cooking materials collected at the front end of the pot are thrown upwards and fall backwards; the pot is moved backwards through the actions of lifting and pulling, so that the materials thrown upwards and backwards fall into the pot again. Thereby realizing the pot lifting and feeding actions manually finished by the cook in an automatic and mechanized mode.
Under the driving action of the driving device, the swinging shaft periodically slides back and forth on the curve guide rail, namely, the position of the swinging shaft periodically changes on the curve guide rail. The pan driving device periodically pushes or pulls down the rear end of the pan, so that the front end of the pan (such as the far end of the pan relative to the swing shaft) is periodically lifted or lowered correspondingly.
In addition, in the invention, the distance from the fulcrum of the lever system to the central line of the cooker is less than the radius of the cooker, so that the volume of the equipment is reduced; more importantly, as the pot and the fulcrum are in continuous motion, when the cooking materials in the pot fall down after being thrown from the front end of the pot to the rear upper part, most of the cooking materials fall on the rear end of the pot, and then the pot moves to the front lower part, so that the cooking materials move from the rear end of the pot to the front end of the pot; therefore, not only can the cooking materials in the pot be prevented from being always concentrated at the front end of the pot, but also the heat waste and the fuel waste caused by insufficient utilization of the heat of the pot body are avoided; the cooking materials can be spread in the pot sufficiently, and the cooking materials can be heated in the pot uniformly.
According to another embodiment of the invention, the oscillating axis is located in a non-central position of the pot, biased to one side of the pot. The purpose of this arrangement is to provide a greater vertical movement of the front end of the pot (e.g. the distal end of the pot relative to the axis of oscillation) and thus a longer acceleration of the cooking material in the pot before it is thrown, thus achieving the desired upward throwing movement of the cooking material.
According to another embodiment of the invention, the pan is displaced vertically at the same time as the horizontal displacement of the distal end of the pan relative to the axis of oscillation during the entire movement of the pan.
According to another embodiment of the invention, the front end of the pot moves forward and moves downward at the same time; the front end of the pot moves backwards and upwards at the same time. The forward and downward movement process of the front end of the cooker leads the cooking materials in the cooker to be concentrated at the front end of the cooker, and the backward and upward movement process of the front end of the cooker leads the cooking materials in the cooker to be accelerated upwards and backwards, thereby finishing the backward throwing action.
According to another specific embodiment of the invention, at any time of the movement of the pot, the pot rotates by taking the swinging shaft as a rotation center; the position of the oscillating shaft periodically changes on the curved guide rail during the whole movement process of the pot.
According to another embodiment of the invention, the pot driving device is a single-power or multi-power linkage mechanism.
According to another specific embodiment of the invention, the cookware driving device is a single-power crank-slider mechanism, which comprises a crank, a connecting rod and a slider (sliding column); the crank is driven by a power device; the tail end of the connecting rod is directly or indirectly fixedly connected with the cooker; the sliding block is a swinging shaft and is connected to the positions of the two ends of the connecting rod.
Specifically, for example, the curved guide rail is a curved guide groove in which the swing shaft slides; one end of the connecting rod is a crank end hinged with the crank, and the other end of the connecting rod is a pot end fixedly connected with the pot; the swing shaft is fixedly connected to the connecting rod and is positioned between the crank end and the pot end.
The pot is fixedly connected with the swinging shaft, and is pushed and dragged by the connecting rod through the swinging shaft to rotate and move according to the curved motion track determined by the curved guide groove.
The power device is used for driving the crank to rotate, and can be various motors and speed reducers matched with the motors.
The rotation of the crank drives the connecting rod to move back and forth, so that the swinging shaft (the sliding column) reciprocates along the sliding groove, and the cooker fixedly connected with the sliding column reciprocates along the sliding groove.
The rotation of the crank causes the reciprocating motion and the reciprocating rotation of the pot along the sliding groove, and the two motions are combined to form the pot tossing motion.
Furthermore, the connecting rod and the curved guide groove are two in parallel in pairs; the sliding column penetrates through the two connecting rods, and two ends of the sliding column are respectively positioned in the two guide grooves.
The curved guide groove comprises two identical guide groove blocks which are arranged in parallel in pairs, and each guide groove block is provided with a guide groove; the guide groove comprises a horizontal section and an arc line section which is connected with the horizontal section and has a downward opening.
According to another embodiment of the invention, the curved track comprises a downwardly opening arc segment.
According to another embodiment of the invention, the pot and the connecting rod form a lever system taking the swinging shaft as a fulcrum, and the swinging shaft slides or rolls back and forth along the curve guide rail.
According to another embodiment of the invention, the pot further comprises a holding mechanism, the holding mechanism comprises a ring body for embedding the pot body into the holding mechanism and a handle, and the connecting rod is fixedly connected with the handle. The handle part is connected with the sliding column through a connecting piece. For example, two holes are arranged on the connecting sheet, and the handle part and the sliding column of the pot holding mechanism are respectively arranged in the two holes on the connecting sheet in a penetrating way.
Furthermore, the connecting rod, the sliding column, the handle part of the holding mechanism and the connecting sheet are fixedly connected into a whole and move synchronously.
According to another embodiment of the invention, the device further comprises a pushing tool and a corresponding driving device, wherein the pushing tool is used for pushing and pulling the material to assist the material to move and turn over; the driving device drives the pushing tool to do periodic reciprocating motion, and the motion period of the pushing tool is consistent with that of the cooker.
For example, the drive means may be a crank and rocker mechanism comprising a crank, a rocker, and a connecting rod therebetween; the tail end of the pushing tool is connected to the connecting rod or the rocker. For another example, the driving device may be a dual-crank mechanism, which includes a driving crank, a driven crank, and a connecting rod pushing tool connected between the driving crank and the driven crank. The two schemes are that the crank rotates to drive the pushing tool to move as follows: during the pan backward motion, push away and dial the material that the instrument promoted in the pan and remove to the pan front end, when the pan moved forward, push away and dial the instrument and leave the pan, the material was moved near the front dead point position at the pan and is thrown, and the pan moves backward this moment, and the material that is thrown will fall back to the pan rear end, so relapse.
The cranks in the two schemes can be driven by a single power device, and can also be driven by the power device of the pot dragging type pot moving device through the transmission of a belt and a chain.
It is worth noting that: the moving direction of the pushing tool can be the same as the moving direction of the pot, so that materials in the pot can be accelerated to leave the pot; the motion direction of the pot can be opposite to that of the pot, so that the materials are accelerated to turn over; and when the pot is static, the materials can be independently stirred or stirred, so that the pot turning is further optimized.
Preferably, the pushing tool can be a round-bottomed frying pan which has a spherical structure, so that the materials are better polymerized and dispersed in the pushing process, and the mixing or heating is more uniform.
Compared with the prior art, the invention has the following beneficial effects:
the equipment of the invention has small volume, and can effectively realize the top pan movement of the pan; more importantly, the cooking material in the pot can be prevented from being always concentrated at the front end of the pot, and further, the heat waste and the fuel waste caused by insufficient utilization of the heat of the pot body are avoided; the cooking materials can be spread in the pot sufficiently, and the cooking materials can be heated in the pot uniformly.
The present invention will be described in further detail with reference to the accompanying drawings.
