Description

Technical Field

[0001] The present invention relates to a cooking method and its equipment, in particular to a cooking method and cooking equipment for stir-frying Chinese dishes. Background Art

[0002] For the cooking of Chinese dishes, the taste of stir-frying in a small pot is usually better than that in a large pot. One of the reasons is that the materials in the small pot are heated relatively faster and more evenly. To promote the uniform and rapid heating of the materials, the existing automatic / semi-automatic cooking equipment is usually equipped with a stirring mechanism for stirring the materials.

[0003] For example, Chinese Patent Document CN101836815A discloses a stirring mechanism of a cooking device, including one or more groups of stirring rods, and each group of stirring rods includes two or more stirring rods; wherein, the stirring mechanism further includes a group of mounting seats corresponding to the stirring rod groups, and the stirring rods in each stirring group are respectively hinged on a mounting seat, and the stirring rods in each stirring group can swing around the corresponding hinge axis of the stirring rod. The advantage of this rod-shaped stirring tool is that it can play a good role in dispersing the materials and avoid the adhesion and agglomeration of the materials, but there is a defect that it is difficult to turn over the materials. For example, for block-shaped materials, there is a problem that the side of the material in contact with the pot is overheated, while the opposite side is underheated. Therefore, the problem of uneven heating of the materials occurs, which affects the quality of the dishes.

[0004] Chinese Patent Document CN2778144Y discloses a mechanized stir-frying machine, which is composed of a frame, a frying pan device, a frying spoon device, a sealing device, a heat preservation housing, a fire control device, a scraping shovel, a blast burner, and a control system; the frying pan is driven by a motor reducer to rotate horizontally; the frying spoon is driven by a motor reducer to rotate vertically; the vertical movement of the frying spoon and the horizontal movement of the frying pan are combined into a compound movement to realize the turning of the vegetables in the frying pan by the frying spoon. This stir-frying machine also has the deficiency of poor mixing effect of the materials, and there is also a problem that the materials are easily pushed / pulled outside the frying pan. Summary of the Invention

[0005] The main object of the present invention is to provide a cooking device that can well stir and turn over the materials, and can effectively solve the problem that the cooking materials fall outside the cooking utensil; at the same time, the device also has the advantage of being convenient for miniaturization.

[0006] To achieve the above main object, the present invention provides a cooking device, including a cooking pot, a flipping bracket, a flipping driving device, and a stirring system disposed on the flipping bracket. The stirring system includes a stirring driving device, a stirring member, a stirring auxiliary member, and a trajectory transformation mechanism; the flipping driving device drives the flipping bracket to rotate around a horizontally arranged flipping axis, so that the stirring member moves into or out of the cooking pot, and the stirring auxiliary member correspondingly contacts the cooking pot or moves away from the cooking pot; the stirring driving device drives the stirring member to rotate vertically around a horizontally arranged stirring axis to stir the materials in the cooking pot; the trajectory transformation mechanism connects the stirring member and the stirring driving device and is configured to change the spatial position of the stirring axis when the stirring member rotates, so that the material stirring part of the stirring member is close to the inner wall of the cooking pot and the inner wall of the stirring auxiliary member during the rotation process; the inner walls of the stirring auxiliary member and the cooking pot form a smooth transition at the contact position, and the inner wall of the stirring auxiliary member is formed to converge towards the radially inner side of the cooking pot.

[0007] The material stirring part being close to the inner walls of the cooking pot and the stirring auxiliary member can be that the material stirring part is in direct contact with its inner wall, or there is a certain gap between the material stirring part and its inner wall (in this case, the material stirring part can also take away the materials attached to the inner walls of the cooking pot and the stirring auxiliary member).

[0008] In the above technical solution, when the stirring member stirs the materials, it rotates vertically. The material stirring part is close to the inner walls of the cooking pot and the stirring auxiliary member, driving the materials to move along the curved surface formed by the cooking pot and the stirring auxiliary member to the stirring auxiliary member above the cooking pot and then fall. Moreover, the inner wall of the stirring auxiliary member is formed to converge towards the radially inner side of the cooking pot, which can well guide the materials to fall back into the pot and turn over, making the materials evenly heated; the configuration of the stirring auxiliary member also solves the problem in the prior art that the stirring member rotates vertically and easily pushes / pulls the materials to the outside of the cooking pot.

[0009] In the above technical solution, by adjusting the rotation trajectory of the material stirring part through the trajectory transformation mechanism, it can be adapted to cooking pots of different shapes (such as spherical pots and flat-bottomed pots); the trajectory transformation mechanism can also limit the rotation range of the material stirring part outside the cooking pot, which is beneficial to the miniaturization of the stirring auxiliary member and the cooking device. Separating the stirring auxiliary member from the cooking pot is also convenient for the miniaturization of the cooking pot and the dish serving operation.

[0010] In contrast, in the technical solution disclosed in CN2778144Y, the frying spoon rotates vertically, and the spatial range occupied by the frying spoon when rotating outside the cooking pot is very large; at this time, if a stirring auxiliary member is configured on the cooking pot, the stirring auxiliary member must be at least larger than the rotation range of the frying spoon to avoid interference between the stirring auxiliary member and the frying spoon, which will result in a significant increase in the volume of the device.

[0011] In the present invention, the stirring auxiliary member may be provided only on one side where the stirring member rotates out of the cookware (for example, when the stirring system is configured such that the stirring member rotates in one direction), or may be provided on opposite sides where the stirring member rotates out of / into the cookware (for example, when the stirring system is configured such that the stirring member can rotate in both directions). According to a specific embodiment of the present invention, the stirring auxiliary member is formed in an annular or arc shape that matches the shape of the mouth of the cookware. In particular, the annular shape can better confine the material within the cookware. Preferably, the flipping bracket has an annular or arc-shaped mounting portion for mounting the stirring auxiliary member, so as to facilitate the formation of a stable connection between the stirring auxiliary member and its mounting portion.

[0012] According to a preferred embodiment of the present invention, the inner wall of the stirring auxiliary member has a material limiting mechanism. The material limiting structure includes two limiting ribs arranged side by side, and the material stirring part is located between the two limiting ribs when passing through the stirring auxiliary member. Due to the limitation of the limiting ribs, the material driven to the inner wall of the stirring auxiliary member by the material stirring part is confined within the area between the two limiting ribs. That is to say, the material driven to the inner wall of the stirring auxiliary member is always located within the action area of the material stirring part when passing through the stirring auxiliary member, thereby effectively suppressing the adhesion of the material to the stirring auxiliary member.

[0013] According to a specific embodiment of the present invention, the trajectory transformation mechanism is a cam mechanism. The structure of the cam mechanism is relatively simple and occupies relatively less space, which is beneficial to the miniaturization of the equipment.

[0014] Preferably, the cam mechanism includes:

[0015] A cam member, which is fixedly connected to the flipping bracket and has a shaft hole and a cam groove surrounding the shaft hole;

[0016] A rotating guide rail, which is arranged to rotate around the central axis of the shaft hole of the cam member under the drive of the stirring drive device;

[0017] A slider member, which is slidably arranged on the rotating guide rail and is fixedly connected to the stirring shaft of the stirring member; a roller is provided on the slider member and is rotatably or rollably engaged in the cam groove.

[0018] In the present invention, the cookware is preferably arranged to make a horizontal rotational movement around the central axis of the cookware under the drive of the cookware rotation drive device. The combination of the horizontal rotation of the cookware, the vertical rotation of the stirring member, and the limitation and guidance of the material by the stirring auxiliary member can achieve a better material mixing effect, the overall heat uniformity of the material is also better, and it is not easy to stick to the pan.

[0019] Preferably, the stirring auxiliary member is formed in an annular or arc shape matching the shape of the pot opening of the cookware. One or more scraping blades that do not contact the stirring member are provided at the lower edge of the stirring auxiliary member. The scraping blades are close to the inner wall of the cookware (i.e., directly contact the inner wall of the cookware or have a predetermined gap through which the material is not easily passed) when the stirring auxiliary member is closed, and are configured to make the material located at the edge of the cookware gather towards the center of the cookware when the cookware rotates. Generally, the cookware heating device mainly heats the central area of the cookware, and the material stirring part also passes through the central area of the cookware when stirring and rotating. Therefore, controlling the distribution of the material in the central area of the cookware during the cooking process can make the material be better turned and stirred, and thus be heated faster and more evenly.

[0020] As a specific embodiment of the present invention, the cookware is arranged on a pot ring, and a linkage structure that enables the cookware to rotate with the pot ring is provided between the pot ring and the cookware; the pot ring has a toothed ring arranged along its circumference, and the toothed ring meshes with a gear driven by a cookware rotation driving device.

[0021] As a more specific embodiment of the present invention, a cookware limiting mechanism for preventing the cookware from shaking is formed between the cookware and the pot ring; preferably, the pot ring has a first stepped portion arranged along its circumference on its radial inner side, the cookware is provided with a second stepped portion along its circumference, the second stepped portion is supported on the first stepped portion, and the first stepped portion and the second stepped portion constitute the cookware limiting mechanism; more preferably, the first stepped portion and the second stepped portion are inclined relative to the horizontal plane.

[0022] According to a preferred embodiment of the present invention, the stirring member has a material stop portion provided at the front end of its stirring shaft. Thereby, it is possible to prevent or reduce the material from falling onto the stirring shaft of the stirring member.

[0023] In order to more clearly elaborate the purpose, technical solution and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and specific embodiments. Description of the Drawings

[0035] Figure 1 and 2 show the structure of a preferred embodiment of the cooking device of the present invention, Figure 1 in which the stirring system is in a non-working position, Figure 2 in which the stirring system is in a working position. Please refer to Figure 1 and 2 , the cooking device has a generally flat main cabinet 10, a display / touch screen 14 and a plurality of operation keys 15 are arranged on the front side surface of the main cabinet 10, a spherical cookware 21 is arranged on the cooking tabletop 11, and a cookware heating device for heating the cookware 21 is arranged in the main cabinet 10. The cookware heating device can be, for example, a gas, electromagnetic or light wave heating device.

[0036] In this preferred embodiment, a horizontally rotatable pot ring 22 is further arranged on the cooking tabletop 11, the cookware 21 is carried on the pot ring 22, and a linkage structure for enabling the cookware 21 to rotate with the pot ring 22 is provided between the cookware 21 and the pot ring 22. As a specific embodiment of the linkage structure, notch portions 223 are arranged on opposite sides of the pot ring 22, handles 212 are arranged on opposite sides of the cookware 21, and the handles 212 are engaged with the notch portions 223 to form a linkage structure between the cookware 21 and the pot ring 22. After cooking is completed, the cookware 21 can be removed from the cooking tabletop 11 by an operator or a mechanical hand holding the handle 212, the cooked dish can be poured out of the cookware 21, and the cleaning operation of the cookware 21 can be performed.

[0037] A pot rotation driving device for driving the pot 21 to rotate horizontally is also provided inside the main box body 10. Figure 3 A preferred embodiment of the pot rotation driving mechanism is shown. As Figure 3 shown, a gear ring 222 is provided on the inner circumference of the pot ring 22. The gear ring 222 meshes with a gear 233 provided on the rotating shaft 232, and the rotating shaft 232 is connected to a pot rotation motor 231 which serves as the pot rotation driving device. Thus, the pot rotation motor 231 drives the pot ring 22 to rotate through a gear transmission mechanism, and the pot ring 22 drives the pot 21 to perform a horizontal rotational movement around the central axis of the pot 21 through a linkage structure. In some other embodiments, the gear ring 222 can be provided on the outer circumference of the pot ring 22; in still other embodiments, a gear ring meshing with the gear 233 can be directly provided on the outer circumference of the pot 21, and at this time the pot ring can be fixed.

[0038] Please continue to refer to Figure 3 and Figure 4 , and a pot limiting mechanism for preventing the pot 21 from shaking is provided between the pot 21 and the pot ring 22. In the present invention, the shaking of the pot refers to the pot movement that changes the attitude or position of the pot, such as the rotation of the pot in the vertical direction. As a specific embodiment of the pot limiting mechanism, the pot ring 22 has a first step portion 221 provided along its circumferential direction on its radial inner side, and the pot 21 has a second step portion 211 provided along its circumferential direction. The second step portion 211 is supported on the first step portion 221, thereby forming a pot limiting mechanism for preventing the pot 21 from shaking. Preferably, the first step portion 221 and the second step portion 211 are inclined with respect to the horizontal plane. The first step portion 221 hooks the second step portion 211 like a hook, and the pot limiting effect is better.

[0039] Refer to again Figure 1 and 2 , and a first sub-box body 12 and a second sub-box body 13 protruding upward are respectively provided at the left rear and right rear of the main box body 10. An automatic feeding system for feeding materials into the pot 21 is provided at the second sub-box body 13. In this preferred embodiment, the automatic feeding system includes a material box assembly 50, a material box rotation driving mechanism for driving the material box assembly 50 to rotate horizontally, and a material box flipping driving mechanism for driving the material box to flip and feed materials. The specific structure of this automatic feeding system can be referred to the disclosure of Chinese Patent Document CN201811076308.9, and will not be elaborated here.

[0040] The stirring system is arranged on the turnover bracket 31 and includes a stirring motor 41 as a stirring driving device, a stirring member 43, a stirring auxiliary member 34, and a track conversion mechanism connecting the stirring motor 41 and the stirring member 43. The turnover bracket 31 is rotatably arranged vertically between the first sub-box body 12 and the second sub-box body 13. Specifically, the turnover bracket 31 has a rotation axis arranged substantially horizontally, and this rotation axis can be carried on the first sub-box body 12 and / or the second sub-box body 13, or carried on corresponding support members located inside the first sub-box body 12 and / or the second sub-box body 13. In this preferred embodiment, a turnover motor 33 (see Figure 5 ) is arranged inside the first sub-box body 12. The turnover motor 33 is connected to the rotation axis of the turnover bracket 31 to drive the turnover bracket 31 to rotate vertically around its rotation axis. In other embodiments, the turnover driving device can be, for example, an electric push rod or a hydraulic push rod.

[0041] In the preferred embodiment of the present invention, as the turnover bracket 31 rotates, the stirring system moves between a non-working position as shown in Figure 1 and a working position as shown in Figure 2 . Among them, in the non-working position, the stirring auxiliary member 34 is separated from the cookware 21, and the stirring member 43 is located outside the cookware 21; in the working position, the stirring member 43 is located inside the cookware 21, and at the same time, the stirring auxiliary member 34 is in contact with the edge of the cookware 21. An arc-shaped smooth transition is formed at the contact between the stirring auxiliary member 34 and the inner wall of the cookware 21, and the inner wall of the stirring auxiliary member 34 is formed to converge towards the radially inner side of the cookware 21. In the working position, the stirring shaft 432 of the stirring member 43 is in a horizontal state, and the stirring member 43 can rotate vertically around the stirring shaft 432 to stir the materials in the cookware 21.

[0042] As shown in Figure 5 and 6 , in the preferred embodiment of the present invention, the turnover bracket 31 includes an arm bracket 311. The arm bracket 311 is formed as a frame body in a substantially L shape, and the upper side and the rear side of the arm bracket 311 are connected to a substantially L-shaped cover body 312 (see Figure 2 ). Bearings 3111 are arranged on two opposite side walls of the arm bracket 311, and the bearings 3111 carry the rotation axis of the turnover bracket 31. A plurality of mounting holes 3112 for installing, for example, water spray nozzles and oil spray nozzles are arranged on the front wall of the arm bracket 311 facing the cookware 21, and the mounting holes 3112 are located above the stirring auxiliary member 34. That is to say, the cooking device of the present invention can have an automatic water adding system and an automatic oil adding system for respectively adding water and oil into the cookware 21. It should be noted that the up and down positional relationships in the present invention are described based on the state when the stirring system 34 is in the working position as shown in Figure 2 .

[0043] The flipping bracket 31 further has an annular mounting portion 32 formed integrally with the boom 311, and the inner peripheral surface of the annular mounting portion 32 is formed as an inclined surface such as a conical surface. The stirring auxiliary member 34 is also annular, and a circular opening adapted to the annular mounting portion 32 is formed at its upper end, and the upper end of the stirring auxiliary member 34 is connected to the mounting portion 32. Two scraping blades 342 that do not contact the stirring member 43 are provided at the lower edge of the stirring auxiliary member 34. When the stirring system is in the working position, the scraping blades 342 are close to the inner wall of the cookware 21, and the scraping blades 342 are inclined toward the downstream side in the rotation direction of the cookware 21, so that the materials located at the edge of the cookware 21 gather toward the center of the cookware 21 when the cookware 21 rotates.

[0044] The stirring motor 41 and the trajectory transformation mechanism are arranged inside the flipping bracket 31, and the stirring shaft 432 of the stirring member 43 passes through the waist-shaped hole 3113 of the flipping bracket 31 (see Figure 6 ) and the avoidance hole / slot 343 on the stirring auxiliary member 34 (see Figure 1 ). The stirring member 43 includes a material stirring portion 431, a stirring shaft 432, and a material stopping portion 433. Among them, the material stirring portion 431 can be formed, for example, in the shape of a sheet, a rod, a comb, or a combination of these shapes. In this preferred embodiment, the material stirring portion 431 includes stirring blades formed with tooth-shaped protrusions. The material stopping portion 433 is circular, is provided at the front end of the stirring shaft 432, and the surface adjacent to the material stirring portion 431 is formed as an inclined surface inclined with respect to the stirring shaft 432, and the surface adjacent to the stirring shaft 432 is perpendicular to the stirring shaft 432. In this preferred embodiment, the material stopping portion 433 is formed integrally with the material stirring portion 431 and is detachably connected to the stirring shaft 432. It is easy to understand that the material stopping portion 433 can also be formed integrally with the stirring shaft or assembled to the stirring shaft as a separate component.

[0045] The trajectory transformation mechanism is configured to change the spatial position of the stirring shaft 432 when the stirring member 43 rotates, thereby transforming the rotation trajectory of the stirring member 43, so that the material stirring part 431 of the stirring member 43 is close to the inner wall of the cookware 21 and the stirring auxiliary member 34 during the stirring rotation process. It should be noted that when the material stirring part 431 rotates past the stirring auxiliary member 34, it can always be close to the inner wall of the stirring auxiliary member 34, or only be close to the inner wall of the stirring auxiliary member 34 for a period of time when it just rotates upward into the range of the stirring auxiliary member 34. The relative two sides of the inner wall of the stirring auxiliary member 34 are provided with material limiting structures, and the material limiting structures include two limiting ribs 341 arranged side by side. When the material stirring part 431 rotates past the stirring auxiliary member 34, it is located between the two limiting ribs 341. The stirring system is configured to make the stirring member 43 rotate in one direction or two directions. When the stirring member 43 rotates in one direction, the material limiting structure can be provided only on the side of the inner wall of the stirring auxiliary member 34 corresponding to the stirring member 43 rotating out of the cookware 21.

[0046] Figures 7 - 9 The structure of a preferred embodiment of the trajectory transformation mechanism is shown. Please refer to Figures 7 - 9 , the trajectory transformation mechanism includes a cam member 421, a rotating guide rail 422 and a slider member 423. Among them, the cam member 421 is fixedly connected to the flipping bracket 31 and has a shaft hole 4211 and a cam groove 4212 surrounding the shaft hole 4211; the rotating guide rail 422 is arranged to rotate around the central axis of the shaft hole 4211 under the drive of the stirring motor 41; the slider member 423 is slidably arranged on the rotating guide rail 422 and is fixedly connected to the stirring shaft 431 of the stirring member 43 (for example, formed integrally or connected by screws); a roller 4231 that can be rotatably or rollably engaged in the cam groove 4212 is provided on the slider member 423.

[0047] Specifically, there is a bearing 4213 arranged in the shaft hole 4211 between the power output shaft 411 of the stirring motor 41 and the cam member 421; a connecting flange 424 is fixedly sleeved on the power output shaft 411 and is fixedly connected to the rotating guide rail 422; a chute 4221 is formed on the rotating guide rail 422, and the slider member 423 has a slide rail 4232 slidably engaged in the chute 4221; a guide post 4233 is arranged at one end of the slider member 423, and the roller 4231 is rotatably or rollably arranged at the free end of the guide post 4233. Among them, the guide post 4233 forms a bolt structure and is fixed to the slider member 423 by a nut 4234.

[0048] Figure 11 is a front cross-sectional view when the preferred embodiment of the cooking device of the present invention is cooking, and the cross-section passes through the central axis of the cookware 21. From Figure 11It can be seen that in the preferred embodiment of the cooking device of the present invention, the inner wall of the stirring auxiliary member 22 is formed as an arc surface, and an arc-shaped smooth transition is formed between the stirring auxiliary member 22 and the inner wall of the cookware 21, and the radius of the stirring auxiliary member 22 is smaller than the radius of the cookware 21. The cam member 421 correspondingly has a Figure 10 shown track groove 4212. When the roller 4231 is located within the track of section A-D, the material stirring part 431 makes a close movement with the inner wall of the cookware 21; when the roller 4231 is located within the track of section A-B, the material stirring part 431 makes a close movement with one side of the inner wall of the stirring auxiliary member 34; when the roller 4231 is located within the track of section B-C, the material stirring part 431 rotates above the stirring auxiliary member 34 and starts to rotate idly; when the roller 4231 is located within the track of section C-D, the material stirring part 431 contacts the stirring auxiliary member 34 downward and starts to make a close movement with the other side of the inner wall of the stirring auxiliary member 34. In this way, reciprocating, the material is turned and stirred. By adjusting the track of the cam groove 4212, the spatial position of the stirring shaft 432 can be adjusted, and the rotation track of the material stirring part 431 can be changed, so as to adapt to cookware of different shapes and the combination of the cookware and the stirring auxiliary member.

[0049] In the present invention, on the one hand, the track transformation mechanism can ensure that the material stirring part 431 is close to the inner walls of the cookware 21 and the stirring auxiliary member 34 during stirring, and on the other hand, it can limit the rotation range of the material stirring part 431 outside the range of the cookware, which is convenient for miniaturization of the cooking device. Expressed from another angle, if there is no track transformation mechanism, then to ensure that the material stirring part 431 is close to the inner wall of the cookware 21 during stirring, a spherical cookware must be used, and the rotation radius of the material stirring part 431 is approximately equal to the radius of the spherical cookware. It is easy to understand that in this case, the rotation range of the material stirring part 431 will be very large, and as a result, the volume of the stirring auxiliary member and the device will increase significantly.

[0050] It should be noted that the multi-link mechanism can also achieve complex known motion laws and tracks in a plane / space. Therefore, in other embodiments of the present invention, the track transformation mechanism can also be implemented by a multi-link mechanism.

[0051] The cooking device of the preferred embodiment of the present invention can be used, and a cooking program is called by a control system to execute the following cooking method:

[0052] ⑴ Control the automatic feeding system to put cooking materials into the cookware;

[0053] ⑵ Move the stirring member into the cookware and make the stirring auxiliary member contact the edge of the cookware;

[0054] ⑶ Control the stirring drive device to drive the stirring member to rotate vertically. During the rotation of the material stirring part of the stirring member, it is close to the inner wall of the cooking utensil and the stirring auxiliary member, so that the material falls back into the cooking utensil after being driven by the material stirring part to rise to the stirring auxiliary member; at the same time, during all or part of the time period when the stirring member rotates vertically, control the cooking utensil to make a horizontal rotational movement so that the material in the cooking utensil makes a relative movement with the cooking utensil;

[0055] ⑷ Remove the stirring member from the cooking utensil, and at the same time separate the stirring auxiliary member from the cooking utensil, and then take out the cooked dish from the cooking utensil.

[0056] Among them, the cooking materials may be put in at one time or in batches. And the cooking materials can be put in when the stirring system is in the working position and the non-working position; that is to say, the order of steps ⑴ and steps ⑵ and ⑶ in the present invention can be unrestricted. In addition, the putting in of the cooking materials can also be manually carried out by the operator under the prompt of the cooking equipment; the above cooking method also includes other steps that are not described but are well known to those skilled in the art, such as putting in cooking aids (such as oil, salt, seasonings, etc.), sauces into the cooking utensil; during at least part of the time period of the above steps ⑴ to ⑶, heating the cooking utensil by using the cooking utensil heating device; and so on.

[0057] Although the present invention has been depicted through specific embodiments above, it should be understood that within the scope of the invention of the present invention, all equivalent improvements made in accordance with the present invention shall be covered by the protection scope of the present invention.
