When cooked by one cooking machine, the stirring mechanism is used to stir the food materials in a fixed stirring track, and the cooking parameters such as cooking time, cooking fire or cooking steps are different for different kinds of dishes.

[0003] However, in actual cooking process, different dishes generally need to be stirred in different forms according to their actual types to achieve the best cooking effect.

[0095] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific examples described herein are merely intended to explain the present application and not to limit the present application.

[0096] The cooking machine is an intelligent device that can realize automatic cooking, which has a stirring mechanism for stirring food materials, the stirring mechanism including a first spatula for stir-frying food materials in a pot to make the food materials evenly heated, and a second spatula for scraping the food materials at the edge of the pot back to the center of the pot. In the existing stirring mechanism, the first spatula and the second spatula are driven to rotate and revolve respectively by a planetary gear structure to realize the stir-frying of the food materials, the first spatula specifically moves in a spiral attitude around the circumference of the pot, and the second spatula moves in a circular motion along the edge of the pot.

[0097] The existing planetary gear structure includes a planet carrier, a plurality of planet gears internally meshed with the planet carrier, and a central gear located at the center of the plurality of planet gears and meshed with the planet gears. Since the central gear is fixedly arranged at the middle of the planetary gear structure and meshed with the planet gears, the diameter of the planet gears is limited by the planet carrier, and the maximum diameter cannot reach more than one half of the planet carrier, resulting in that the rotation of the first spatula driven by the planet gears can only be adjusted within a certain range.

[0098] And the furthest point of the stirring track drawn by the stirrer on the spatula across the pot surface and the center line of the pot body projection plane serve as an auxiliary line, the auxiliary line of each period and the auxiliary line of the adjacent period form an included angle, and the size of the included angle directly affects the degree of rotation of the first spatula. Since the diameter of the planet gears is relatively small compared with the planet carrier, the included angle generated by the stirring track is small, so that the first spatula can only stir a part of the area of the pot during stir-frying, and the other part of the area is still in a stacked state waiting to be stirred. Such stirring track is suitable for limited cooking recipes and cannot meet the different cooking recipe needs of users.

[0099] Moreover, when the cooking machine is put into market use, it is often used to cook all kinds of dishes, and different cooking machines are not adapted for different kinds of dishes. When cooked by one cooking machine, the stirring mechanism is used to stir the food materials with a fixed stirring track, except that the cooking time, cooking firepower or cooking steps of different kinds of dishes are different.

[0100] However, in the actual cooking process, different dishes generally need to be stirred in different forms according to their actual types to achieve the best cooking effect. For example, some dishes that are not easy to cook need to be stir-fried to a large extent to ensure that they are evenly heated and cooked faster, some dishes that are easy to break need to be stir-fried to a small extent to avoid breaking, and some dishes can be stir-fried to a normal extent.

[0101] Because it's impossible to precisely adapt a particular cooking machine or model to a specific type of dish—meaning it cannot be used for a specific type of food—and cannot meet the specific cooking / mixing requirements of the dish, the food often fails to achieve optimal cooking results. Furthermore, neither users nor managers are fully aware of the exact mixing level the cooking machine provides; they can only roughly judge by visually observing the movement of the mixing head, making accurate application of the cooking machine difficult.

[0102] In the technical solution of the present invention, the first rotation parameter of the first stirring mechanism is adjusted based on the demand, and the first stirring mechanism is controlled to rotate with the adjusted first rotation parameter and output a stirring trajectory, so that the stirring trajectory formed by the rotation of the first stirring mechanism can meet the stirring / cooking requirements of the dish. Furthermore, the cooking equipment can be accurately adapted to the cooking of a certain type of dish according to the stirring trajectory, so as to achieve the purpose of specializing in a specific machine to obtain better cooking results.

[0103] Example 1

[0104] Please see Figure 1 , Figure 2 , Figure 13 and Figure 18 In the method for obtaining the stirring trajectory of the cooking device 1000 according to an embodiment of the present invention, the cooking device 1000 includes a pot 200 and a first stirring mechanism 13 driven by a motor to rotate within the pot 200. The method for obtaining the stirring trajectory includes the following steps:

[0105] S1: Determine the requirement to obtain the stirring trajectory of the cooking equipment;

[0106] S2: Adjust the first rotation parameter of the first stirring mechanism according to the required parameters;

[0107] S3: Control the rotation of the first stirring mechanism according to the adjusted first rotation parameters; and

[0108] S4: Outputs the stirring trajectory formed after the first stirring mechanism rotates.

[0109] In the method for obtaining the stirring trajectory of the cooking device 1000 in this embodiment of the invention, the actual requirement for obtaining the stirring trajectory is the stirring / cooking requirement of the dish during the cooking process. Based on the requirement, the first rotation parameter of the first stirring mechanism 13 is adjusted, and it is controlled to rotate with the adjusted first rotation parameter and output the stirring trajectory. This ensures that the stirring trajectory formed after the first stirring mechanism 13 rotates can meet the stirring / cooking requirements of the dish, achieving a better cooking effect. Furthermore, the cooking device 1000 can be accurately adapted to the cooking of a certain type of dish according to the stirring trajectory, achieving the purpose of dedicated machine for dedicated use to obtain a better cooking effect. It also allows the user and / or owner of the cooking device 1000 to no longer rely solely on visual judgment to determine the stirring trajectory, but can more clearly and intuitively grasp the current stirring trajectory for accurate operation, thus improving the intelligence and operability of the cooking device 1000.

[0110] Specifically, the cooking device 1000 in this embodiment of the invention is a stir-fry machine. The stir-fry machine includes a stirring head 100 suspended above the pot 200. It includes components commonly used in automatic stir-fry machines, such as a motor, gears, gear rings, mounting structure, rotating structure, and a first stirring mechanism 13. The first stirring mechanism 13 is specifically located between the stirring head 100 and the pot 200. The first stirring mechanism 13 includes a connecting rod connected to the main body of the stirring head 100. The motor drives the components directly or indirectly connected to the first stirring mechanism 13 to rotate within the pot 200. At the same time, the first stirring mechanism 13 also revolves relative to the pot 200 (with the vertical line between the center of the stirring head 100 and the center of the pot 200 as the center of revolution / or the connection point between the connecting rod and the stirring head 100 as the center of revolution) to cover the stir-frying range of the ingredients in the pot 200.

[0111] The first stirring mechanism 13 is provided with two first spatulas spaced apart and at a certain angle to each other. The two first spatulas are arranged in opposite directions and are both in contact with the surface of the pot 200. When the first stirring mechanism 13 rotates, the two first spatulas at both ends move in different directions and form an arc-shaped stirring trajectory on the pot 200 from the beginning of the movement. After the two first spatulas return to the starting point, the combined stirring trajectory forms a petal shape.

[0112] The cooking apparatus 1000 of this embodiment includes at least Figure 2 to Figure 8 , Figure 13 to Figure 16 as well as Figure 17 to Figure 24 The three different structures shown, namely the stirring trajectory acquisition method of the cooking device 1000 in the embodiments of the present invention, are applicable to at least the above three different cooking devices 1000. The specific structures of the above three cooking devices 1000 will be described one by one below.

[0113] I. In a cooking device 100 of one embodiment of the present invention, such as Figure 2 to Figure 8As shown:

[0114] The stirring head 100 and the pot 200 are mounted on the machine body 300. The stirring head 100 is located above the pot 200. The stirring head 100 specifically includes a mounting base 1, a drive assembly 2, a first gear 3, a second gear 4, an upper gear ring 5, a rotating disk 6, a lower gear ring 7, and a planetary gear 8.

[0115] Specifically, the mounting base 1 is fixed on the body 300, the drive assembly 2 is located on the mounting base 1, the first gear 3 is located on the mounting base 1 and connected to the drive assembly 2 and driven to rotate by the drive assembly 2, the second gear 4 is located on the mounting base 1 and meshes with the first gear 3 for transmission, the upper gear ring 5 is rotatably located on the mounting base 1 and sleeved outside the first gear 3, the first gear 3 is internally meshed with the upper gear ring 5, the rotating disk 6 is sleeved outside the upper gear ring 5 and fixed, the second stirring mechanism 14 is fixed on the rotating disk 6, the lower gear ring 7 is located below the upper gear ring 5 and is rotatably fixed to the rotating disk 6, the second gear 4 extends to the lower gear ring 7 and is internally meshed with the lower gear ring 7, the planetary gear 8 is fixed on the rotating disk 6 and is internally meshed with the lower gear ring 7, the planetary gear 8 is used to fix the stirring blade, the planetary gear 8 is fixed with the first stirring mechanism 13, the first stirring mechanism 13 and the second stirring mechanism 14 both extend into the pot 200 to stir the food.

[0116] When the cooking device 1000 is working, the power of the drive component 2 is transmitted to the first gear 3 to make it rotate. The first gear 3 drives the upper gear ring 5 and the second gear 4 to rotate, which in turn drives the upper gear ring 5 to drive the rotating disk 6 and the second gear 4 to drive the lower gear ring 7 to rotate. The planetary gear 8 is fixed on the rotating disk 6 and meshes with the lower gear ring 7. The rotating disk 6 can drive the planetary gear 8 to revolve when it moves, and the lower gear ring 7 drives the planetary gear 8 to rotate on its own axis. Thus, the first stirring mechanism 13 fixed on the planetary gear 8 can achieve both revolution and rotation.

[0117] In the first stirring head 100 provided in the above embodiments of the present invention, the lower gear ring 7 only needs to mesh with one planetary gear 8 to drive the planetary gear 8 to rotate. The diameter of the planetary gear 8 has a very wide adjustable range. It can be adjusted in a range less than or equal to half the diameter of the lower gear ring 7, or in a range greater than half the diameter of the lower gear ring 7. The rotation of the planetary gear 8 is wider than the adjustable range. The stirring trajectory of the stirring blade set on the planetary gear 8 can achieve a variety of changes. For example, it can move circumferentially along the inner wall of the pot 200 to achieve gradual stir-frying, or the stirring blade can directly approach the center of the pot 200 to stir-fry the ingredients evenly. Thus, it can adapt to the cooking of different ingredients, and the cooking effect is more ideal and more in line with market demand.

[0118] In addition, power is input to the first gear 3, which meshes with the upper gear ring 5 and simultaneously transmits power to the second gear 4, which then meshes with the lower gear ring 7. By adopting a small gear driving a large gear structure, a large torque can be output while requiring less force and consuming less power, thus reducing the requirements for the drive component 2 and lowering the cost of power.

[0119] To better understand the change in the rotation trajectory of the first stirring mechanism 13 from loose to dense when the planetary gear 8 changes its rotation ratio, please refer to Table 1 and... Figure 9 to Figure 12 The first stirring mechanism 13, fixed on the planetary gear 8, consists of two stirring blades 131. When the rotational speed ratio and the revolution speed ratio of the first stirring mechanism 13 are constant, the trajectories of the two stirring blades 131 are the same, only differing in phase. The stirring of the ingredients in the pot 200 is mainly performed by the first stirring mechanism 13. Therefore, the stirring trajectory is actually mainly the motion trajectory of the first stirring mechanism 13.

[0120] First gear (number of teeth) Upper ring gear (number of teeth) Lower ring gear (number of teeth) Planet gear (number of teeth) Revolution speed ratio Rotation speed ratio Angle of inclination 12 41 36 12 0.29268293 4 55.38 12 41 36 18 0.29268293 6 83.51 12 41 36 24 0.29268293 8 111.78 12 41 36 28 0.29268293 9.33333333 130.93 12 41 36 30 0.29268293 10 137.49 12 41 36 32 0.29268293 10.6666667 148.11

[0121] Table 1

[0122] Please refer to Table 1. When the number of teeth of the first gear 3, the upper gear ring 5, and the lower gear ring 7 remains constant, the change in the included angle (hereinafter referred to as the trajectory angle) is obtained by changing the number of teeth of the planetary gear 8. At this time, the revolution speed ratio remains constant. Table 1 shows the process of the number of teeth of the planetary gear 8 relative to the lower gear ring 7 changing from less than half to more than half. As the number of teeth of the planetary gear 8 increases sequentially, the degree of the included angle also increases linearly. At the same time, the rotation speed ratio also gradually increases.

[0123] Please see Figure 9 , Figure 9 To simulate the stirring trajectory of the first stirring mechanism 13 by taking one of the parameters in the region where the inner diameter of the planetary gear 8 is less than half that of the lower gear ring 7, when the lower gear ring 7 has 36 teeth and the planetary gear 8 has 12 teeth, the angle between the auxiliary lines of two adjacent petal cycles is 55.38°. At this time, the stirring trajectory of a single stirring blade is to move along the circumference of the side wall of the pot 200.

[0124] Please see Figure 10 , Figure 10 The stirring trajectory of the double-blade stirrer, when stacked, is also a spiral motion around the 200mm sidewall of the pot. This method is suitable for cooking fragile foods, such as tofu, as the stirring trajectory moves circumferentially, requiring minimal stirring.

[0125] Please see Figure 11 , Figure 11This is a schematic diagram of a single stirring blade trajectory simulated by taking one of the parameters in the area where the inner diameter of the planetary gear 8 is greater than half of the lower gear ring. When the lower gear ring has 36 teeth and the planetary gear 8 has 32 teeth, the included angle between two adjacent petals is 148.11°. During the rotation of a single stirring blade, the relative positions of the first petal cycle and the second petal cycle tend to be at opposite ends of the pot 200. In this way, when stir-frying, it can be stir-fried close to the center of the pot 200, making the stir-frying more even. It can avoid the situation where the stirring blade only stirs the food in one side of the pot 200 for a certain period of time, while the food in the other side is in a state of accumulation.

[0126] See Figure 12 , Figure 12 The stirring trajectory of the double-blade stirrer, after being superimposed, ensures that the relative positions of the adjacent first and second petal cycles during the rotation of the two blades tend to be at both ends of the pot 200. This allows for even stirring of ingredients within the pot 200, preventing areas from piling up when stirring on one side, thus improving the stir-frying effect. This method is suitable for foods that are not easily broken or require vigorous stirring, such as vegetables or meats. The stirring trajectory moves symmetrically towards both ends of the pot 200, resulting in a high degree of stirring.

[0127] Please see Figure 4 Specifically, the mounting base 1 includes a first mounting portion 11 and a second mounting portion 12 extending downward from the first mounting portion 11. The drive assembly 2, the first gear 3, and the second gear 4 are fixed to the first mounting portion 11, and the rotating disk 6 is rotatably fixed to the second mounting portion 12. Further, a rotating body 10 is provided between the second mounting portion 12 and the rotating disk 6, and the second mounting portion 12 is connected to the rotating disk 6 via the rotating body 10. The rotating body 10 allows the rotating disk 6 to be mounted on the mounting base 1 without interfering with the rotation of the rotating disk 6. In this embodiment, the rotating body 10 can be a rotary support bearing.

[0128] Please see Figure 3 to Figure 4 Furthermore, the drive assembly 2 includes a drive element 21 (i.e., the motor in Embodiment 1), a transmission assembly 22, and a drive gear 23. The drive element 21 is mounted on the mounting base 1, and the transmission assembly 22 is mounted on the mounting base 1 and is driven to rotate by the drive element 21. Specifically, the transmission assembly 22 includes a drive gear 221 connected to the output end of the drive element 21 and a driven gear 222 meshing with the drive gear 221. The drive gear 23 is mounted on the mounting base 1 and cooperates with the transmission assembly 22 for transmission. That is, the drive gear 23 meshes with the driven gear 222 and is driven to rotate by the driven gear 222. The first gear 3 meshes with the drive gear 23, thus realizing the power transmission to the first gear 3.

[0129] Specifically, in order to prevent the drive gear 23 from shaking during subsequent force transmission, one end of the drive gear 23 is fixed by the mounting base 1, and the other end is connected and fixed by the support member 20. The support member 20 is connected to the mounting base 1. In this way, both ends of the drive gear 23 are firmly fixed to the mounting base 1, so that a stable transmission relationship can be formed when the force is subsequently transmitted to the first gear 3 and the second gear 4.

[0130] In this embodiment, the driving component 21 may be, but is not limited to, a motor.

[0131] Please see Figure 4 Furthermore, in this embodiment, the inner diameter of the upper gear ring 5 is larger than the inner diameter of the lower gear ring 7, so as to avoid interference between the second gear 4 and the upper gear ring 5 when the second gear 4 meshes with the lower gear ring 7.

[0132] Please continue reading Figure 4 Furthermore, the rotating disk 6 includes an upper disk body 61 fixed to the upper gear ring 5 and a lower disk body 62 connected below the upper disk body 61 and fitted outside the lower gear ring 7. The planetary gear 8 is fixed to the lower disk body 62. Thus, by fixing the planetary gear 8 to the lower disk body 62, and the lower disk body 62 being connected to the upper disk body 61, it is convenient to fix the planetary gear 8 on the rotating disk 6.

[0133] Specifically, the lower disc 62 includes a fixing part 621 extending below the lower gear ring 7, and the planetary gear 8 is fixed on the fixing part 621 to support the planetary gear 8. Furthermore, the stirring head 100 also includes a bearing 9, the outer ring of which is fixed inside the lower disc 62, and the lower gear ring 7 is fixed to the inner ring of the bearing 9. In this way, the lower gear ring 7 can be fixed while still being able to rotate.

[0134] II. In another embodiment of the cooking device 1000 of the present invention, such as Figure 13 to Figure 16 As shown:

[0135] The stirring head 100 and the pot 200 are mounted on the machine body 300. The stirring head 100 is located above the pot 200. The stirring head 100 includes a mounting base 1, a drive assembly 2, a rotating disk 3, a first transmission component 4, a second transmission component 5, a third transmission component 6, and a cover 8.

[0136] Specifically, the drive assembly 2 is mounted on the mounting base 1, and the rotating disk 3 is mounted on the mounting base 1 and connected to the drive assembly 2. The rotating disk 3 is driven to rotate by the drive assembly 2. The first transmission member 4 is fixed on the axis of the rotating disk 3 and rotates with the rotating disk 3. The first transmission member 4 is provided with a first stirring mechanism 13, and the rotating disk is provided with a second stirring mechanism 14. The second transmission member 5 is fixed on the rotating disk 3 and is driven by the rotating disk 3 to rotate around the axis of the rotating disk 3. The second transmission member 5 cooperates with the first transmission member 4 to drive the rotation. The third transmission member 6 is mounted on the rotating disk 3 and cooperates with the second transmission member 5 to drive the rotation. The third transmission member 6 is provided with a universal joint 7 for connecting the first stirring mechanism 13. The cover 8 is fixed below the rotating disk 3. The first stirring mechanism 13 passes through the middle of the bottom of the cover 8 and extends out of the cover 8. The cover 8 is rotatably provided with a ball valve 9 at the position where the first stirring mechanism 13 passes through.

[0137] When the drive assembly 2 drives the rotating disk 3 to rotate, since the first transmission member 4 is fixed on the axis of the rotating disk 3, the rotating disk 3 drives the first transmission member 4 to rotate. The second transmission member 5 is fixed on the rotating disk 3 and can rotate around the axis of the rotating disk 3. That is, the second transmission member 5 is eccentrically set on the rotating disk 3. When the rotating disk 3 rotates, the second transmission member 5 can revolve around the rotating disk 3. The third transmission member 6 is also eccentrically set on the rotating disk 3 and rotates in cooperation with the second transmission member 5. That is, the third transmission member 6 can revolve around the rotating disk 3 when the rotating disk 3 rotates.

[0138] Simultaneously, the second transmission component 5 can drive the third transmission component 6 to rotate, causing the third transmission component 6 to rotate on its own axis. The first stirring mechanism 13 is fixed on the third transmission component 6 and can achieve both revolution and rotation, thereby achieving the stir-frying of ingredients. A ball valve 9 is provided on the first stirring mechanism 13. When the first stirring mechanism 13 revolves and rotates, it can also rotate flexibly at the position of the ball valve 9. In this way, the movement trajectory of the first stirring mechanism 13 is more likely to be closer to the center of the pot 200 or even pass through the center of the pot 200, resulting in more even stir-frying of ingredients and preventing the accumulation of ingredients in the center of the pot 200, thus achieving better cooking results.

[0139] In addition, the third transmission component 6 is indirectly transmitted to the first transmission component 4 through the second transmission component 5. On the one hand, it can make the rotation direction and revolution direction of the first stirring mechanism 13 opposite to achieve a better effect. On the other hand, the rotation ratio and revolution ratio of the first stirring mechanism 13 can be adjusted according to the needs, thereby realizing the adjustment of the stirring trajectory. That is, with different rotation ratios and revolution ratios, the first stirring mechanism 13 stirs at different frequencies to meet the needs of stir-frying different dishes.

[0140] In the second type of stirring head 100 provided in the above embodiments of the present invention, the first stirring mechanism 13 is connected to the cover 8 through the ball valve 9. While being driven to rotate and revolve, the first stirring mechanism 13 can also rotate flexibly with a larger rotation dimension, thereby changing the stirring trajectory of the first stirring mechanism 13. The stirring trajectory is more inclined to the center of the pot 200 or even passes through the center of the pot 200, so that the ingredients are stir-fried more evenly and the cooking effect is better.

[0141] It should be noted that, in order to expand the stirring range of the ingredients within the pot 200, the first stirring mechanism 13 is typically inclined; that is, the first stirring mechanism 13 is not coaxially arranged with the third transmission member 6. Therefore, the universal joint 7 is used to transmit the circumferential force generated by the rotation of the third transmission member 6 to the first stirring mechanism 13, thereby changing the direction of force transmission. In this embodiment, the universal joint 7 can be a universal joint.

[0142] Furthermore, the sum of the diameters of the first transmission component 4 and the second transmission component 5 is less than the center distance between the first transmission component 4 and the third transmission component 6. This avoids structural interference between the third transmission component 6 and the first transmission component 4, thus preventing any impact on the transmission performance of the third transmission component 6.

[0143] In this embodiment, the first transmission component 4, the second transmission component 5, and the third transmission component 6 can all be gears.

[0144] Furthermore, the ball valve 9 is located at the center of the three-dimensional space of the cookware 200.

[0145] In this way, it can be ensured that the spatula will pass through the center of the pot when stir-frying, so that the food in the center of the pot can be stir-fried more evenly and the stir-frying effect is better.

[0146] Please see Figure 15 Specifically, the drive assembly 2 includes a drive component 21 (i.e., the motor in Embodiment 1), a fourth transmission component 22, and a fifth transmission component 23. The drive component 21 is mounted on the mounting base 1. The fourth transmission component 22 is mounted on the mounting base 1 and connected to the drive component 21, being driven to rotate by the drive component 21. The fifth transmission component 23 is mounted on the mounting base 1 and cooperates with the fourth transmission component 22 to transmit rotation. The fifth transmission component 23 is connected and fixed to the rotating disk 3. Specifically, the rotating disk 3 and the fifth transmission component 23 can be connected and fixed using a partially nested and fastened method.

[0147] The drive component 21 drives the rotating disk 3 to rotate through the cooperation of the fourth transmission component 22 and the fifth transmission component 23. On the one hand, the power output of the drive component 21 can be adjusted according to the needs. On the other hand, it can facilitate the flexible setting of the installation position of the drive component 21 on the mounting base 1.

[0148] In this embodiment, the driving component 21 may be, but is not limited to, a motor.

[0149] Please continue reading Figure 15 Furthermore, the rotating disk 3 is located below the fifth transmission component 23, and the central axis of the rotating disk 3 is provided with a connecting shaft 31. One end of the connecting shaft 31 is fixed to the rotating disk 3, and the other end passes through the fifth transmission component 23 and is fixed to the mounting base 1. The first transmission component 4 is fixed to the connecting shaft 31.

[0150] The rotating disk 3 is located below the fifth transmission component 23, which avoids the stirring head 100 from being too large in the horizontal direction. It also facilitates the connection between the rotating disk 3 and the fifth transmission component 23, meaning that the two can be connected by a partially nested fixing method. The connecting shaft 31 is provided to facilitate the fixing of the first transmission component 4, and one end of the connecting shaft 31 is fixed to the mounting base 1, making the installation of the first transmission component 4 more stable and the structure more stable and reliable during power transmission.

[0151] Please see Figure 14 Furthermore, a fixing ring 10 is provided on the outer sleeve of the rotating disk 3. The fixing ring 10 is connected and fixed to the mounting base 1. A bearing 20 is connected between the fixing ring 10 and the rotating disk 3.

[0152] The fixing ring 10 serves two purposes: firstly, it protects the rotating disk 3 from objects entering it during operation; secondly, it fixes the rotating disk 3 in place, preventing it from shaking during rotation and making the structure more stable and reliable.

[0153] It is worth noting that in the second type of cooking device 1000 shown in this invention, the gears, gear rings, or rotating disks (such as rotating disk 3, first transmission member 4, and third transmission member 6) used to drive the first stirring mechanism 13 and the second stirring mechanism 14 are also applicable to the parameters in Table 1 above, and the stirring trajectory formed by the movement of the first stirring mechanism 13 is also similar to that shown above. Figure 9 to Figure 12 The stirring trajectories shown are roughly the same.

[0154] III. In another embodiment of the cooking apparatus 1000 provided by the present invention, such as Figure 17 to Figure 24 As shown:

[0155] The stirring head 100 and the pot 200 are mounted on the machine body 300. The stirring head 100 is located above the pot 200. The stirring head 100 specifically includes a mounting base 1, a drive assembly 3, a rotating disk 4, a first transmission component 5, and a second transmission component 6.

[0156] Specifically, all drive components 3 are mounted on the mounting base 1. The rotating disk 4 is mounted on the mounting base 1 and connected to the drive components 3. The rotating disk 4 is driven to rotate by the drive components 3. The first transmission member 5 is fixed to the rotating disk 4 and is driven by the rotating disk 4 to rotate around the axis of the rotating disk 4 to achieve revolution. The first transmission member 5 is used to connect the first stirring mechanism 13. The rotating disk 4 is provided with a second stirring mechanism 14. The second transmission member 6 is mounted on the mounting base 1 and located on the axis of the rotating disk 4. The first transmission member 5 and the second transmission member 6 cooperate to drive each other to rotate, so that the first transmission member 5 can travel on the circumference of the second transmission member 6, thereby achieving rotation.

[0157] The drive assembly 3 drives the rotating disk 4 to rotate. The first transmission member 5, which is set on the rotating disk 4, can rotate around the axis of the rotating disk 4, so that the first transmission member 5 can revolve. Then, the first stirring mechanism 13 set on the first transmission member 5 can revolve. At the same time, the first transmission member 5 and the second transmission member 6 cooperate to rotate, so that the first transmission member 5 can rotate on its own while being transmitted with the second transmission member 6, so that the first stirring mechanism 13 set on the first transmission member 5 can also rotate on its own while revolving around the disk.

[0158] In the third stirring head 100 provided in the above embodiments of the present invention, only when the driving component 3 transmits the power of the driving component 31 to the first transmission component 5, and then the first transmission component 5 and the second transmission component 6 cooperate to drive the rotation, the first stirring mechanism 13 fixed on the first transmission component 5 can be rotated and revolved. In other words, the rotation and revolution of the second transmission component 5 can be achieved by only using the cooperation of two transmission components. The structure for realizing the rotation and revolution can be simplified, which can simplify the equipment, reduce the assembly difficulty and parts cost, and at the same time, the faults caused by mechanical movement are easy to repair, reducing maintenance costs.

[0159] In this embodiment, the first transmission member 5 and the second transmission member 6 can adopt a single gear structure, and the first transmission member 5 and the second transmission member 6 are driven by meshing. In addition, the first transmission member 5 and the second transmission member 6 can be directly meshed, or another gear can be used to achieve indirect meshing of the first transmission member 5 and the second transmission member 6. In this way, the indirect meshing method can change the stirring trajectory of the first stirring mechanism 13, thereby enabling the stirring trajectory of the first stirring mechanism 13 to be changed according to actual cooking needs.

[0160] Please see Figure 20The drive assembly 3 includes a drive component 31 (i.e., the motor in Embodiment 1), a third transmission component 32, and a fourth transmission component 33. The drive component 31 is fixed to the mounting base 1. The third transmission component 32 is fixed to the mounting base 1 and connected to the drive component 31, being driven to rotate by the drive component 31. The fourth transmission component 33 is fixed to the mounting base 1 and cooperates with the third transmission component 32 to transmit rotation. The fourth transmission component 33 is also connected and fixed to the rotating disk 4. By providing the third transmission component 32 and the fourth transmission component 33, the power output of the drive component 31 can be easily converted and transmitted, thereby facilitating the acquisition of the required power.

[0161] In this embodiment, both the third transmission component 32 and the fourth transmission component 33 can adopt a gear structure. In this way, the third transmission component 32 and the fourth transmission component 33 can directly mesh and transmit power, which results in high transmission accuracy and small space occupation, thereby further simplifying the size of the equipment.

[0162] In addition, the third transmission component 32 and the fourth transmission component 33 can also adopt a transmission wheel or a sprocket structure. When a transmission wheel is used, the third transmission component 32 and the fourth transmission component 33 can be driven by a belt; when a sprocket is used, the third transmission component 32 and the fourth transmission component 33 can be driven by a chain.

[0163] In this embodiment, the rotating disk 4 can be located below the fourth transmission member 33 and coaxially arranged with the fourth transmission member 33. The fourth transmission member 33 is fixedly connected around the rotating disk 4, thus ensuring a more stable connection between the rotating disk 4 and the fourth transmission member 33.

[0164] In this embodiment, the drive unit 31 may be, but is not limited to, a motor.

[0165] Please see Figure 18 to 20 Furthermore, the stirring head 100 also includes an adjustment component 7, and a second transmission component 6 is fixed on the adjustment component 7. The first transmission component 5 includes at least two first gears 51 with different numbers of teeth arranged coaxially and spaced apart, and the second transmission component 6 includes at least two second gears 61 with different numbers of teeth arranged coaxially and spaced apart.

[0166] That is, at least two first gears 51 or at least two second gears 61 are arranged in a straight line along their axial direction, and the number of first gears 51 and second gears 61 is equal to ensure one-to-one matching and avoid interference when switching between different first gears 51 and second gears 61. One of the first gears 51 and one of the second gears 61 mesh to realize the revolution and rotation of the first stirring mechanism 13. The adjusting component 7 can drive another first gear 51 to mesh with another second gear 61 to change the different speeds of the first transmission component 5, thereby changing the rotation speed of the first stirring mechanism 13 and thus changing the differential speed ratio between the revolution and rotation of the first stirring mechanism 13. This allows it to adapt to different cooking needs and provides greater flexibility in use.

[0167] Furthermore, when one first gear 51 and one second gear 61 are engaged, the remaining second gears 61 are all misaligned with the remaining first gears 51.

[0168] In this embodiment, two of each of the first gear 51 and the second gear 61 are used. For an example where there are three of each, please refer to [link to example]. Figure 22 The number of teeth of the first gear 51 increases or decreases sequentially, so that the first gear 51 and the second gear 61 located at the first or last position mesh with each other, and the remaining first gears 51 and the second gear 61 are staggered. When the movable rod 71 moves in the same direction, the remaining first gears 51 and the remaining second gears 61 can mesh in sequence, thereby changing the rotation speed of the first transmission member 5.

[0169] also, Figure 22 The diagram shows the movable rod 71 moving sequentially in the same direction. Of course, it is also possible to move in two different directions to achieve a change in the rotational speed of the first transmission member 5. The spacing between the remaining second gears 61 and the first gear 51 in the direction of movement can be set according to the actual movement direction of the movable rod 71.

[0170] Please see Figure 23 The number of teeth of the first gear 51 is not arranged in order of size. The first gear 51 and the second gear 61 located at the first or last position mesh with each other. During the movement, the meshing of different first gears 51 and second gears 61 can also be achieved by moving the movable rod 71 up and down. The remaining first gears 51 and second gears 61 are staggered. When the movable rod 71 moves in the same direction, the remaining first gears 51 and the remaining second gears 61 can mesh in sequence to change the rotation speed of the first transmission member 5.

[0171] See Figure 24The number of teeth of the first gear 51 is not arranged in order of size. At the same time, the first gear 51 and the second gear 61 located in the middle mesh. During the movement, the meshing of different first gears 51 and second gears 61 can also be achieved by moving the movable rod 71 up and down.

[0172] Please see Figure 20 Furthermore, the adjusting assembly 7 includes a movable rod 71, which is movably mounted on the mounting base 1 and passes through the axis of the rotating disk 4. The second transmission member 6 is fixed to the movable rod 71, and at least two second gears 61 are arranged along the moving direction of the movable rod 71. In this way, by moving the movable rod 71, different sets of first gears 51 and second gears 61 can be meshed.

[0173] Please continue reading Figure 20 Furthermore, the adjustment assembly 7 also includes an elastic element 72 and a handle 73. The elastic element 72 is located on the mounting base 1 and provides a preload force to the movable rod 71 to engage the second gear 61 with the first gear 51. The handle 73 is rotatably connected to the movable rod 71, and when the handle 73 rotates, it can drive the movable rod 71 to move. In this way, by driving the movable rod 71 to move, the rotational speed of the first gear 51 can be changed.

[0174] Please see Figure 21 Furthermore, when the handle 73 drives the movable rod 71 to move, there are two of each of the first gear 51 and the second gear 61. The handle 73 includes a connecting part 731 rotatably connected to the movable rod 71 and a hand-held part 732 connected to the connecting part 731. The connecting part 731 is rotatably connected to the movable rod 71 via a connecting shaft 74. The connecting part 731 includes a first plane 731a and a second plane 731b with their outer surfaces adjacent to each other. The distances from the connection point between the connecting part 731 and the movable rod 71 (i.e., at the connecting shaft 74) to the first plane 731a and the second plane 731b are not equal. When the rotating part 731 rotates, the first plane 731a and the second plane 731b can respectively abut against the mounting base 1, and the movable rod 71 moves.

[0175] By utilizing the fact that the distances from the first plane 731a and the second plane 731b to the connecting shaft 74 are not equal, when the first plane 731a and the second plane 731b respectively abut against the mounting base 1, the distance between the connection point of the movable rod 71 and the mounting base changes, and the movable rod 71 moves, thereby enabling the corresponding first gear 51 and second gear 61 to mesh.

[0176] Specifically, the movable rod 71 is sequentially connected to the mounting base 1, the fourth transmission component 33, and the rotating disk 4. The movable rod 71 is provided with a limiting part 711. The elastic element 72 is sleeved on the movable rod 71 and its two ends abut against the limiting part 711 and the mounting base 1 respectively, so that the elastic element is in a stored state under normal conditions. The elastic element 72 is located on the side of the mounting base 1 away from the handle 73. When the handle 73 is rotated and drives the movable rod 73 to move, the elastic element 72 always has tension on the movable rod 71, thereby ensuring that the first gear 51 and the second gear 61 are always in a meshing state.

[0177] In this embodiment, the first plane 731a and the second plane 731b can be transitioned by an arc to facilitate the rotation of the handle 73.

[0178] Furthermore, the rotating disk 4 is provided with a receiving groove 41 that can accommodate part of the second gear 61.

[0179] Thus, when the movable rod 71 moves, part of the second gear 61 can be embedded in the rotating disk 4 to save space in the direction of movement of the movable rod 71, thereby achieving miniaturization of the equipment.

[0180] Furthermore, a support sleeve 9 is provided around the rotating disk 4, and the support sleeve 9 is fixedly connected to the mounting base 1. A bearing 10 is provided between the rotating disk 4 and the support sleeve 9. This improves the connection stability of the rotating disk 4 and the reliability of the mechanical movement process.

[0181] Of course, in other embodiments, the cooking device 1000 may also include other structural configurations, and is not limited to the three mentioned above in this invention. The method for obtaining the stirring trajectory of the cooking device 1000 is also applicable to cooking devices 1000 with other structures.

[0182] Furthermore, the cooking device 1000 of this embodiment also includes a controller. The controller is disposed in the body 300 and connected to the drive component (i.e., motor) in the stirring head 100 to control the stirring action of the stirring head 100, that is, to control the operation of the first stirring mechanism 13 and the second stirring mechanism 14. Moreover, the controller is used to execute the above-described stirring trajectory acquisition method. Parameters or data related to the first stirring mechanism 13, the second stirring mechanism 14, and gears can be manually input or downloaded from the cloud and stored in the controller. When using the cooking device 1000 and needing to acquire the stirring trajectory, the relevant parameters or data can be directly selected through the controller to obtain the stirring trajectory that meets the user's expectations.

[0183] Specifically, to ensure the best cooking effect, the ingredients are generally best cooked and stir-fried (stirred) in the relatively central part of the pot 200. Therefore, the rotation of the first stirring mechanism 13 is designed to be mainly concentrated in the relatively central part of the pot 200 where the ingredients are concentrated, so as to periodically stir the ingredients in the pot 200, ensuring that the ingredients are heated evenly in the relatively central part of the pot 200, and can be mixed with seasonings relatively fully to obtain dishes with better cooking effect.

[0184] Since the first stirring mechanism 13 is composed of two first spatulas, when the first stirring mechanism 13 rotates, the stirring trajectory formed by the two first spatulas is as follows: Figure 8 to Figure 12 The stirring mechanism, as shown, exhibits a uniform spiral motion to achieve thorough and even stirring of the ingredients within the pot 200. The outer circle is formed by the revolution of the second stirring mechanism 14. The stirring trajectory of the first stirring mechanism 13 has its farthest point, meaning the movement of the two first spatulas within the pot 200 has its maximum range. Furthermore, the central and densest parts of the stirring trajectory are close to the center of the vertical projection of the pot 200. This means the rotation of the first stirring mechanism 13 is more concentrated in the central part of the pot 200, allowing the ingredients piled up in the center of the pot 200 to be stirred and separated, resulting in more even heating.

[0185] The second stirring mechanism 14 revolves within the pot 200, performing a periodic motion along the outer periphery of the pot 200. The second stirring mechanism 14, close to the outer periphery of the pot 200, revolves around the center of the vertical projection of the pot 200. This scrapes food stirred to the opposite edge of the pot 200 by the first stirring mechanism 13 back to the center, allowing it to be stirred again and ensuring thorough heating. Furthermore, the first stirring mechanism 13, while rotating, also revolves within the pot 200 along with the second stirring mechanism 14, thus extensively stirring the food and ensuring effective cooking.

[0186] To ensure that the first stirring mechanism 13 and the second stirring mechanism 14 can work simultaneously and to simplify the structure of the cooking equipment 1000, in this embodiment of the invention, the first stirring mechanism 13 and the second stirring mechanism 14 are driven by the same motor and the same drive gear (such as the drive gear in the three types of cooking equipment 1000 mentioned above). Transmission gears and related transmission mechanisms are provided between the drive gear and the first stirring mechanism 13, and between the drive gear and the second stirring mechanism 14, so that when the drive gear rotates, the first stirring mechanism 13 and the second stirring mechanism 14 are driven simultaneously and perform rotational and revolutionary motions respectively, thereby achieving the purpose of combined stirring of the ingredients in the pot 200.

[0187] It is worth noting that the stirring trajectory in this embodiment of the invention is mainly formed by the rotation and revolution of the first stirring mechanism 13. The rotation of the first stirring mechanism 13 has the main influence on the cooking effect. Since the trajectory formed by the revolution of the second stirring mechanism 14 is a circle along the edge of the pot 200, it will not have a significant impact on the food accumulated in the middle of the pot 200.

[0188] In this embodiment of the invention, the factors affecting the stirring trajectory of the cooking device 1000 are the rotational speed of the first stirring mechanism 13 and the revolution speed of the second stirring mechanism 14, more specifically, the ratio of the rotational speed of the first stirring mechanism 13 to the revolution speed of the second stirring mechanism 14, i.e., rotational speed / revolutional speed. When the above ratio changes, the density of the stirring trajectory will also change accordingly.

[0189] Therefore, by specifically adjusting the rotation speed of the first stirring mechanism 13 and / or the revolution speed of the second stirring mechanism 14, the density of the stirring trajectory can be adjusted. However, it is worth noting that the rotation speed of the first stirring mechanism 13 and the revolution speed of the second stirring mechanism 14 cannot be adjusted proportionally. If they are adjusted proportionally, the ratio of the rotation speed / revolution speed will not change, and the purpose of adjusting the stirring trajectory cannot be achieved.

[0190] If you want to change the rotation speed of the first stirring mechanism 13 or the revolution speed of the second stirring mechanism 14 by increasing or decreasing the power of the motor, although you can change the actual values ​​of the two, since the first stirring mechanism 13 and the second stirring mechanism 14 are driven by the same motor, from the perspective of motor control, the rotation speed of the first stirring mechanism 13 and the revolution speed of the second stirring mechanism 14 will increase or decrease synchronously and proportionally. At this time, the ratio of rotation speed / revolution speed will not change. Therefore, it can only speed up or slow down the rotation frequency of the first stirring mechanism 13 and the second stirring mechanism 14, and will not affect the formed stirring trajectory, that is, it will not change the shape of the stirring trajectory.

[0191] The stirring trajectory output by the cooking device 1000 in this embodiment of the invention is actually affected by the gears and / or transmission mechanisms corresponding to the first stirring mechanism 13 and the second stirring mechanism 14. Therefore, by adjusting or replacing the parameters of the gears and / or transmission mechanisms corresponding to the first stirring mechanism 13 and / or the second stirring mechanism 14, such as changing the size and number of teeth of the gears / transmission mechanisms, the rotation speed of the first stirring mechanism 13 and the revolution speed of the second stirring mechanism 14 can be adjusted and changed, so as to further adjust and change the stirring trajectory output by the cooking device 1000.

[0192] It is worth mentioning that adjusting or changing the stirring trajectory by rotating on its own axis and revolving on its own axis should be understood in this embodiment of the invention as adjusting or changing the density of the stirring trajectory, rather than adjusting or changing the shape of the stirring trajectory. However, if the structural parameters of the first stirring mechanism 13 are adjusted, such as the angle and position of the first spatula, the shape of the stirring trajectory can be adjusted or changed. That is, if the structure of the first stirring mechanism 13 is fixed, then the shape of the stirring trajectory is also fixed.

[0193] The rotational speed of the first stirring mechanism 13 and the revolution speed of the second stirring mechanism 14 in this embodiment of the invention indirectly reflect the size and dimensions of each transmission mechanism / gear in the stirring head 100. According to mechanical principles, the relationship between rotational speed and gear size, number of teeth, etc., is known and will not be elaborated here. The speed ratio obtained by comparing the rotational speed of the first stirring mechanism 13 with the revolution speed of the second stirring mechanism 14 is actually the ratio of the gear and / or transmission mechanism driving or transmitting the first stirring mechanism 13 to the gear and / or transmission mechanism driving or transmitting the revolution of the second stirring mechanism 14. In this embodiment of the invention, a fixed stirring trajectory can be obtained by setting a fixed rotational speed / revolution speed ratio; similarly, a varying stirring trajectory can be obtained by adjusting the rotational speed / revolution speed ratio.

[0194] In step S1, the required stirring trajectory can be of varying degrees, such as dense, sparse, or moderate. For example, some dishes require thorough coating with sauce, necessitating denser stirring, thus requiring a denser stirring trajectory from the cooking device 1000. Conversely, some dishes may be fragile, requiring only sparser stirring, thus requiring a sparser stirring trajectory from the cooking device 1000. The specific stirring requirements for a particular dish can be derived from feedback on dishes cooked by the cooking device 1000 or from recipes stored within the cooking device 1000.

[0195] Since the stirring of the ingredients in the pot 200 is mainly accomplished by the rotation of the first stirring mechanism 13, in step S2, after determining the acquisition requirements, the first rotation parameter of the first stirring mechanism 13 can be adjusted based on the acquisition requirements to achieve the purpose of adjusting the stirring effect on the ingredients. In this embodiment of the invention, the first rotation parameter is a parameter that affects the rotation of the first stirring mechanism 13, such as the rotation speed of the first stirring mechanism 13, the rotation angle during rotation, or the driving power of the motor, etc.

[0196] In this embodiment of the invention, the stirring trajectory formed by the first stirring mechanism 13 when it rotates can be adjusted by adjusting the first rotation parameter. Different first rotation parameters have different effects on the stirring trajectory. Therefore, it is necessary to make an accurate and reasonable selection according to different actual needs, so that the stirring trajectory formed by the first stirring mechanism 13 after adjusting the first rotation parameter can meet the user's needs, that is, the stirring of the dish by the first stirring mechanism 13 can meet the user's needs or the cooking requirements of the dish.

[0197] The stirring trajectory formed after the first stirring mechanism 13 rotates is output, allowing the user to clearly and intuitively grasp the actual situation of the stirring trajectory. The output can be displayed on the screen of the cooking equipment 1000, allowing the user to directly view the shape of the stirring trajectory. Alternatively, it can be pushed to a user terminal communicating with the cooking equipment 1000. This way, even if the user is not near the cooking equipment 1000, they can promptly grasp the actual situation of the stirring trajectory, facilitating remote control.

[0198] More specifically, in one embodiment, the first rotation parameter after each adjustment can be plotted with the corresponding output stirring trajectory to form a graph and stored in the storage unit of the cooking device 1000 or in the cloud. In this way, when the first rotation parameter needs to be adjusted again, if the graph shows the adjusted first rotation parameter, there is no need to calculate and adjust again. The first stirring mechanism can be directly controlled to rotate and the corresponding stirring trajectory can be output, reducing the calculation work required by the cooking device 1000 and improving the efficiency of use.

[0199] For example, in one application scenario of the method for obtaining the stirring trajectory of the cooking device 1000 in this embodiment of the invention, the user inputs his / her own requirements for obtaining the stirring trajectory on the buttons or touch screen of the cooking device 1000 or on an external terminal. The requirements may specifically include the need to obtain a denser, sparser, or generally default stirring trajectory, as well as the specific density, sparseness, or default degree, etc.

[0200] The controller determines the specific content of the acquisition requirements and performs analysis and calculation to determine the specific first rotation parameters of the first stirring mechanism 13 that need to be adjusted and the specific values ​​of the first rotation parameters adjustment. For example, if the stirring trajectory is relatively dense, the first rotation parameters need to be increased, and how much the first rotation parameters need to be increased to achieve the required density. Or, if the stirring trajectory is relatively sparse, the first rotation parameters need to be decreased, and how much the first rotation parameters need to be decreased to achieve the required sparseness.

[0201] After the controller determines the adjustment method and adjustment value of the first rotation parameter, it controls the first stirring mechanism 13 to rotate with the adjusted first rotation parameter. At this time, the resulting stirring trajectory corresponds to the user's acquisition needs and the cooking needs (requirements) of the dish, thereby enabling better cooking of the dish.

[0202] Example 2

[0203] Please see Figure 25 Furthermore, the first rotational parameter includes the rotational speed of the first stirring mechanism, and step S2 includes the following steps:

[0204] S21: Adjust the rotation speed of the first stirring mechanism according to the required output;

[0205] Step S3 includes the following steps:

[0206] S31: Control the rotation of the first stirring mechanism according to the adjusted rotation speed.

[0207] Specifically, in this embodiment of the invention, the rotational speed of the first stirring mechanism 13 is one of the main factors affecting the stirring trajectory it forms, which is one of the main factors affecting the cooking effect of the cooking device 1000. Therefore, if you want to adjust the stirring trajectory of the first stirring mechanism 13, adjusting its rotational speed is one of the most direct and effective methods.

[0208] Therefore, when actually using the cooking equipment 1000, after determining the requirement for obtaining the stirring trajectory, that is, after determining the cooking requirements for the dish, the rotation speed of the first stirring mechanism 13 is adjusted based on the requirement. The rotation of the first stirring mechanism 13 is controlled according to the adjusted rotation speed. At this time, the rotation of the first stirring mechanism 13 satisfies the requirement, that is, the stirring trajectory output by the first stirring mechanism 13 meets the cooking requirements for the dish.

[0209] The conventional method for adjusting the rotation speed of the first stirring mechanism 13 is to adjust the power of the motor. However, in this embodiment of the invention, the rotation speed of the first stirring mechanism 13 is adjusted by adjusting the gear unit (such as a gear, gear ring, or gear disk) that drives the first stirring mechanism 13 to rotate. For details, please refer to Embodiment 3 below.

[0210] Example 3

[0211] Please see Figure 26 Furthermore, the first stirring mechanism is connected to the first toothed unit, and step S21 includes the following steps:

[0212] S211: Adjust the number of the first teeth of the first tooth unit according to the acquisition requirements;

[0213] Step S31 includes the following steps:

[0214] S311: Control the rotation of the first stirring mechanism according to the adjusted first number of teeth.

[0215] In this embodiment of the invention, the first gear unit is directly connected to the first stirring mechanism 13, and the first gear unit is a component that directly drives the first stirring mechanism 13 to rotate. Taking the first cooking device 1000 provided in this embodiment of the invention as an example, the first gear unit is the planetary gear 8 in the first cooking device 1000. If corresponding to the second or third cooking device 1000 provided in this embodiment of the invention, the first gear unit is the third transmission member 6 in the second cooking device 1000 and the first transmission member 5 in the third cooking device 1000.

[0216] In this embodiment of the invention, since the cooking device 1000 has only one motor, and the motor drives the rotation of the first stirring mechanism 13 and the second stirring mechanism 14 simultaneously, if only the output power of the motor is changed to change the speed of the motor, the rotation speed of the first stirring mechanism 13 and the revolution speed of the second stirring mechanism 14 will change simultaneously and proportionally. The ratio between the rotation speed and the revolution speed will not change, so it cannot affect the density of the stirring trajectory, but will only increase the rotation frequency of the first stirring mechanism 13 and the second stirring mechanism 14.

[0217] Therefore, in this embodiment of the invention, the parameter affecting the rotational speed of the first gear unit is actually the number of teeth of the first gear unit itself. That is to say, by adjusting the number of teeth of the first gear unit, the rotational speed of the first gear unit can be adjusted, thereby achieving the adjustment of the rotational speed of the first stirring mechanism 13. For example, the method of adjusting the number of teeth of the first gear unit can be to directly replace or switch to a first gear unit with a different number of teeth that meets the adjustment requirements. For example, in the third cooking device 1000 provided in this embodiment of the invention, the number of teeth can be adjusted by directly switching the first transmission member 5 (first gear unit) with a different number of teeth.

[0218] It is worth mentioning that, since the first stirring mechanism 13 has an irregular structure, it is relatively difficult to directly measure the corresponding rotation speed. In order to avoid increasing the structural complexity of the stirring head 100 by setting a structure for detecting the rotation speed on the first stirring mechanism 13, since the first stirring mechanism 13 is fixedly driven by the first tooth unit and there is no other mechanism for transmission between the two, the rotation speed of the first tooth unit, which is directly fixed to the first stirring mechanism 13 to drive its rotation, can be used as the rotation speed of the first stirring mechanism 13. The rotation speed can be adjusted by adjusting the number of teeth of the first tooth unit. While effectively converting to obtain the rotation speed, it can also avoid adding other structures to the stirring head 100, thus controlling the structural complexity of the stirring head 100 and the cooking device 1000.

[0219] It is worth noting that when the positional relationship between the two first spatulas is fixed, regardless of adjusting the rotational speed of the first stirring mechanism 13 or the second stirring mechanism 14, or adjusting the number of teeth of the first toothed unit or the second toothed unit that drives the second stirring mechanism to revolve (described later), the shape of the stirring trajectory will not change; only the density of the stirring trajectory will change. In other words, changing the position of the two first spatulas will alter the shape of the stirring trajectory to some extent.

[0220] Example 4

[0221] Furthermore, the rotation speed of the first stirring mechanism 13 is in the range of 5 to 500 RPM.

[0222] Specifically, by setting the rotation speed of the first stirring mechanism 13 to the above-mentioned range, the normal rotation of the first stirring mechanism 13 can be satisfied. Furthermore, the above-mentioned rotation speed range is large enough, that is, the range of adjustment of the stirring trajectory is large enough, so that the rotation of the first stirring mechanism 13 can more easily meet the user's needs for obtaining the stirring trajectory.

[0223] In a preferred embodiment, the rotation speed of the first stirring mechanism 13 is in the range of 20 to 200 RPM.

[0224] In this way, on the one hand, it can avoid the cooking efficiency of the cooking equipment 1000 from being affected by the slow rotation speed of the first stirring mechanism 13 affecting its stirring of the food. On the other hand, it can also avoid the structural burden of the cooking equipment 1000 from the excessively fast rotation speed of the first stirring mechanism 13, which would also lead to faster wear and tear on the first stirring mechanism 13. The stirring trajectory output by the first stirring mechanism 13 after adjusting its rotation speed within this range can also adapt to most of the acquisition needs.

[0225] Example 5

[0226] Please see Figure 27 Furthermore, the first rotation parameter also includes the first stirring angle of the first stirring mechanism, and step S2 further includes the following steps:

[0227] S22: Adjust the first stirring angle of the first stirring mechanism according to the required information;

[0228] Step S3 also includes the following steps:

[0229] S32: Control the rotation of the first stirring mechanism according to the adjusted first stirring angle.

[0230] Specifically, in this embodiment of the invention, the first stirring angle is actually the angle between the first stirring mechanism 13 and the pot 200, which is the angle between the two first spatulas and the pot plane. The first stirring angle directly affects whether the stirring trajectory formed by the first stirring mechanism 13 passes through the center of the pot 200. Although it does not cause a huge change to the general outline of the stirring trajectory, it will still have some influence.

[0231] Therefore, in addition to adjusting the first stirring mechanism 13 to adjust the specific form of the stirring trajectory, the stirring trajectory can also be adjusted by adjusting the first stirring angle of the first stirring mechanism 13 so that the stirring trajectory meets the acquisition requirements. For example, when more stirring is needed on the food in the central area of ​​the pot 200, the first stirring angle can be reduced so that the first stirring mechanism 13 is more focused on stirring the food in the central area of ​​the pot 200; when more stirring is not needed on the food in the central area of ​​the pot 200, the first stirring angle can be increased so that the first stirring mechanism 13 is not too focused on stirring the food in the central area of ​​the pot 200.

[0232] Furthermore, please refer to Figure 28 The first stirring angle A is the angle formed by the vertical line between the first stirring mechanism 13 (the two first spatulas) and the center point of the pot opening plane of the pot 200.

[0233] Specifically, from Figure 28 It can be seen that the first stirring angle A affects the density of the stirring trajectory formed by the first stirring mechanism 13 when it rotates in the relatively central position of the pot 200, and determines whether the stirring trajectory passes through the center of the pot 200, that is, determines the stirring effect of the first stirring mechanism 13 on the food in the relatively central position of the pot 200. Figure 28 This is an example of the second type of cooking apparatus 1000 provided in this embodiment of the invention. To determine the position and size of the first stirring angle A in the other two types of cooking apparatus 1000, refer to... Figure 28 The label is sufficient.

[0234] Example 6

[0235] Furthermore, please refer to Figure 29 The first stirring angle A satisfies the formula: the radius r of the pot 200 * the sine of the first stirring angle A = half the width L of the first stirring mechanism, that is, r * sinA = (1 / 2)L.

[0236] Specifically, by designing the first stirring angle A, the radius r of the pot 200, and half (1 / 2) L of the width of the first stirring mechanism 13 to satisfy the above formula, it is ensured that the two first spatulas in the first stirring mechanism 13 can pass through the center point of the bottom of the pot 200, thereby effectively stir-frying the food and further ensuring the cooking effect of the cooking equipment 1000.Figure 29 This is an example of a second cooking device 1000 provided in an embodiment of the present invention. To determine the position and size of the first stirring angle A in the other two types of cooking devices 1000, refer to... Figure 29 The label is sufficient.

[0237] More often, the rotation center of the stirring head 100 coincides with or nearly coincides with the center of the sphere of the pot 200. At this time, the maximum length of the first stirring mechanism 13 is basically equal to the radius of the pot 200, so that the first stirring mechanism 13 can keep in contact with the surface of the pot 200 no matter where it rotates in the pot 200, thus ensuring the stirring effect on the food.

[0238] Example 7

[0239] Furthermore, please refer to Figure 30 Step S1 includes the following steps:

[0240] S11: Determine the initial stirring degree of the ingredients in the cookware 200; and

[0241] S12: Determine the requirement for obtaining the stirring trajectory of the cooking equipment based on the first stirring degree.

[0242] It is understandable that the shape of the stirring trajectory actually reflects the degree of stirring of the food in the cookware 200. Therefore, the need to obtain the stirring trajectory is actually based on the degree of stirring of the ingredients. Thus, if the user determines the first degree of stirring of the ingredients when cooking with the cooking equipment 1000, the need to obtain the stirring trajectory can be determined based on the first degree of stirring.

[0243] For example, different levels of first stirring can be pre-divided into different grades and stored in the controller of the cooking device 1000. When the current cooking device 1000 and its stirring head 100 are used, and the user selects a grade through the controller, the first stirring degree corresponding to the stirring head 100 and the cooking device 1000 can be determined according to the grade. This makes it convenient for the manager of the cooking device 1000 to use the cooking device to cook ingredients and dishes corresponding to its first stirring degree, so that the first stirring mechanism 13 outputs a stirring trajectory that meets the requirements, in order to achieve the best cooking effect.

[0244] Example 8

[0245] Furthermore, please refer to Figure 31 The cooking appliance 1000 also includes a second stirring mechanism 14, which is driven by the same motor as the first stirring mechanism 13 and revolves within the pot 200. Following step S1, the following step is also included:

[0246] S5: Adjust the second rotation parameters of the second stirring mechanism according to the required parameters;

[0247] S6: Control the rotation of the second stirring mechanism according to the adjusted second rotation parameters; and

[0248] S7: Output the stirring trajectory formed by the first stirring mechanism rotating with the second stirring mechanism at the original first rotation parameters or the adjusted first rotation parameters.

[0249] Specifically, in the cooking device 1000, the revolution of the second stirring mechanism 14 in the pot 200 is a periodic movement along the outer peripheral wall of the pot 200. The second stirring mechanism 14 is close to the outer peripheral wall of the pot 200 and makes a circular motion with the center of the vertical projection of the pot 200 as the center. This scrapes the food that has been stirred to the opposite edge of the pot 200 by the first stirring mechanism 13 when it rotates back to the opposite center of the pot 200 and is stirred again by the first stirring mechanism 13, so that the food can be fully heated.

[0250] The revolution of the second stirring mechanism 14 does not actually have a significant impact on the stirring trajectory formed by the rotation of the first stirring mechanism 13. However, since the stirring trajectory is actually affected by the speed ratio between the rotation speed of the first stirring mechanism 13 and the revolution speed of the second stirring mechanism 14, when some second rotation parameters (such as the revolution speed) of the second stirring trajectory 14 are adjusted, the specific shape of the stirring trajectory will be affected.

[0251] Once the acquisition requirements are determined, the second rotation parameters of the second stirring mechanism 13 can be adjusted based on these requirements. In this embodiment of the invention, the second rotation parameters are parameters that affect the rotation of the second stirring mechanism 13, such as the rotation speed, rotation angle, or drive power of the second stirring mechanism 14. By adjusting the second rotation parameters, the stirring trajectory formed by the rotation of the second stirring mechanism 14 can be adjusted. However, different second rotation parameters have different effects on the stirring trajectory. Therefore, it is necessary to make accurate and reasonable selections based on different actual acquisition requirements so that the stirring trajectory formed by the second stirring mechanism 14 after the second rotation parameters are adjusted can meet the user's needs, that is, the stirring of the dish by the second stirring mechanism 14 can meet the user's needs or the cooking requirements of the dish.

[0252] The mixing trajectory formed by the combined rotation of the first mixing mechanism 13 and the second mixing mechanism 14 is output, allowing the user to clearly and intuitively grasp the actual situation of the mixing trajectory. The output can be displayed on the screen of the cooking equipment 1000 for direct viewing, or it can be pushed to the user's terminal, allowing the user to promptly grasp the actual situation of the mixing trajectory even when not near the cooking equipment 1000.

[0253] When a specific second rotation parameter is adjusted, it will affect the coverage range of the second stirring mechanism 14 over the ingredients in the pot 200. For example, if the stirring trajectory of the first stirring mechanism 13 is wider, causing the ingredients to be stirred to a higher position in the pot 200, then the specific second rotation parameter can be increased to increase the coverage range of the second stirring mechanism 14, which can scrape the ingredients back to a relatively central position in the pot 200. If the stirring trajectory of the first stirring mechanism 13 is narrower, causing the ingredients to be confined to a lower position in the pot 200, then the specific second rotation parameter can be decreased to reduce the coverage range of the second stirring mechanism 14, which can more effectively confine the ingredients to a relatively central position in the pot 200.

[0254] Furthermore, the second rotation parameter after each adjustment can be plotted and stored as a corresponding graph with the stirring trajectory. In this way, when the second rotation parameter needs to be adjusted again, if the adjusted value exists in the graph, there is no need to calculate and adjust it again. The second stirring mechanism can be directly controlled to rotate and the corresponding stirring trajectory can be output, thereby improving the efficiency of the cooking equipment 1000.

[0255] It is worth noting that the aforementioned adjustment of the first rotation parameter of the first stirring mechanism 13 in the embodiments of the present invention is based on the premise that the second rotation parameter of the second stirring mechanism 14 is adjusted by different ratios or not adjusted at all. When only the first rotation parameter is changed or the second rotation parameter is adjusted by different ratios, the stirring trajectory can be adjusted to meet the requirements.

[0256] Of course, the premise of adjusting the second rotation parameter of the second stirring mechanism 14 in the embodiments of the present invention is that the first rotation parameter of the first stirring mechanism 13 is not adjusted or not adjusted. However, since the stirring trajectory is more affected by the first stirring mechanism 13, it is easier to obtain a stirring trajectory that meets the requirements. Furthermore, the relevant components of the first stirring mechanism 13 are easier to adjust. Therefore, in general applications, adjusting the first rotation parameter of the first stirring mechanism 13 is a better choice.

[0257] In this embodiment of the invention, the scheme for adjusting the first rotation parameter of the first stirring mechanism 13 and the scheme for adjusting the second rotation parameter of the second stirring mechanism 14 can be a parallel scheme, where the first rotation parameter and the second rotation parameter can be adjusted simultaneously based on the required parameters, that is, the first rotation parameter of the first stirring mechanism 13 and the second rotation parameter of the second stirring mechanism 14 are adjusted simultaneously but not proportionally. Alternatively, the scheme for adjusting the first rotation parameter of the first stirring mechanism 13 and the scheme for adjusting the second rotation parameter of the second stirring mechanism 14 can be a sequential scheme, such as adjusting the first rotation parameter of the first stirring mechanism 13 first based on the required parameters, and then adjusting or not adjusting the second rotation parameter of the second stirring mechanism 14 at different ratios, or adjusting the second rotation parameter of the second stirring mechanism 14 first, and then adjusting or not adjusting the first rotation parameter of the first stirring mechanism 13 at different ratios.

[0258] Example 9

[0259] Furthermore, please refer to Figure 32 The second rotation parameter includes the revolution speed of the second stirring mechanism, and step S5 includes the following steps:

[0260] S51: Adjust the revolution speed of the second stirring mechanism according to the required data;

[0261] Step S6 includes the following steps:

[0262] S61: Control the rotation of the second stirring mechanism according to the adjusted revolution speed.

[0263] Specifically, in this embodiment of the invention, since the first stirring mechanism 13 and the second stirring mechanism 14 are driven by the same motor / drive gear, the stirring trajectory will change when the parameters of either one are adjusted. That is to say, in this embodiment of the invention, the revolution speed of the second stirring mechanism 14 is one of the important factors affecting the stirring trajectory formed by the first stirring mechanism 13. Therefore, adjusting the revolution speed of the second stirring mechanism 13 is one way to adjust the stirring trajectory to meet the requirements or to affect the degree of mixing of the ingredients.

[0264] When using the cooking equipment 1000, after determining the requirement for obtaining the stirring trajectory, that is, after determining the cooking requirements for the dish, the revolution speed of the second stirring mechanism 14 is adjusted based on the requirement to adjust the rotation of the first stirring mechanism 13. The rotation of the first stirring mechanism 13 and the second stirring mechanism 14 is controlled according to the adjusted revolution speed. At this time, the stirring trajectory formed meets the requirement, that is, the stirring trajectory output by the joint rotation of the first stirring mechanism 13 and the second stirring mechanism 14 meets the cooking requirements for the dish.

[0265] Another point worth noting is that, based on factors such as the structural complexity of the control cooking device 1000 in this embodiment of the invention, a structural design is adopted that uses only one motor to simultaneously drive the first stirring mechanism 13 and the second stirring mechanism 14 to rotate. However, because only one motor is used, it is impossible to adjust the rotational speed of the first stirring mechanism 13 or the revolution speed of the second stirring mechanism 14 independently. If the output power of the motor is adjusted, the rotational speed of the first stirring mechanism 13 and the revolution speed of the second stirring mechanism 14 will be adjusted synchronously and proportionally, which cannot achieve the purpose of adjusting the rotational speed / revolution speed ratio, that is, it cannot achieve the purpose of adjusting the density of the stirring trajectory.

[0266] Therefore, in one embodiment, based on a similar structural design, the cooking device 1000 may also be provided with two motors to drive the rotation of the first stirring mechanism 13 and the revolution of the second stirring mechanism 14 respectively.

[0267] Thus, when it is necessary to adjust the first rotational parameter (such as the rotational speed) of the first stirring mechanism 13 or the second rotational parameter (such as the revolution speed) of the second stirring mechanism 14, the rotational speed of the first stirring mechanism 13 or the revolution speed of the second stirring mechanism 14 can be adjusted independently by the corresponding motors to achieve the purpose of adjusting the speed ratio obtained by the rotational speed / revolution speed. This avoids the problem that the speeds of the two mechanisms will be adjusted proportionally due to a single motor driving both the first stirring mechanism 13 and the second stirring mechanism 14 at the same time. Therefore, it is no longer necessary to adjust the gear unit of the first stirring mechanism 13 and the gear unit of the second stirring mechanism 14 to achieve the purpose of adjusting the speeds of the two mechanisms.

[0268] Example 10

[0269] Furthermore, please refer to Figure 33 The second stirring mechanism is connected to the second tooth unit. Step S51 includes the following steps:

[0270] S511: Adjust the number of the second teeth of the second tooth unit according to the acquisition requirements;

[0271] Step S61 includes the following steps:

[0272] S611: Control the rotation of the second stirring mechanism according to the adjusted second number of teeth.

[0273] Taking the first cooking device 1000 provided in the embodiment of the present invention as an example, the second tooth unit is the upper tooth ring 5 in the first cooking device 1000. If it corresponds to the second cooking device 1000 or the third cooking device 1000, the second tooth unit is the structure that directly drives the second stirring mechanism 14 to rotate.

[0274] In this embodiment of the invention, as can be seen from the above description of the first tooth unit, the parameter affecting the rotational speed of the second tooth unit is actually the number of teeth of the second tooth unit itself. Therefore, by adjusting the number of teeth of the second tooth unit, the rotational speed of the second tooth unit can be adjusted, thereby achieving the adjustment of the revolution speed of the second stirring mechanism 14. For example, adjusting the number of teeth of the second tooth unit can be achieved by directly replacing it with a second tooth unit with a different number of teeth that meets the adjustment requirements.

[0275] It is worth mentioning that, since the second stirring mechanism 14 has an irregular structure, it is relatively difficult to directly measure the corresponding revolution speed. In order to avoid increasing the structural complexity of the stirring head 100 by setting a structure for detecting the speed on the second stirring mechanism 14, since the second stirring mechanism 14 is fixedly driven by the second tooth unit and there is no other mechanism for transmission between the two, the speed of the second tooth unit, which is directly fixed to the second stirring mechanism 14 to drive its rotation, can be used as the rotation speed of the second stirring mechanism 14. The speed can be adjusted by adjusting the number of teeth of the second tooth unit. While effectively converting to obtain the rotation speed, it can also avoid adding other structures to the stirring head 100, thus controlling the structural complexity of the stirring head 100 and the cooking device 1000.

[0276] Example 11

[0277] Furthermore, the revolution speed of the second stirring mechanism 14 is in the range of 3 to 300 RPM.

[0278] Specifically, by setting the rotation speed of the second stirring mechanism 14 to the above-mentioned range, the normal rotation of the second stirring mechanism 14 can be satisfied. Furthermore, the above-mentioned revolution speed range is large enough, that is, the range of adjustment of the stirring trajectory is large enough, so that the rotation of the second stirring mechanism 14 can more easily meet the user's needs for obtaining the stirring trajectory.

[0279] In a preferred embodiment, the revolution speed of the second stirring mechanism 14 is in the range of 10 to 100 RPM.

[0280] In this way, on the one hand, it can avoid the second stirring mechanism 14 from being too slow in its revolution speed, which would affect its stirring of the food and further affect the cooking efficiency of the cooking equipment 1000. On the other hand, it can also avoid the second stirring mechanism 14 from being too fast in its revolution speed, which would increase the structural burden of the cooking equipment 1000 and accelerate the wear and tear of the second stirring mechanism 14. After the first stirring mechanism 14 is adjusted within this revolution speed range, the stirring trajectory output by rotating together with the first stirring mechanism 13 can also adapt to most of the acquisition needs.

[0281] Furthermore, the stirring trajectory on the pot 200 has multiple farthest points that are farthest from the center of the pot 200. The first line connecting the center and one farthest point, and the second line connecting the center and another farthest point, form the trajectory angle that affects the stirring trajectory. One farthest point is adjacent to another farthest point.

[0282] like Figure 8 to Figure 12 as well as Figure 34 to Figure 38As shown, the stirring trajectory in this embodiment of the invention consists of curves formed by the first stirring mechanism 13 traversing the surface of the pot 200. The first stirring mechanism 13 performs a spiral-shaped periodic rotation, resulting in a "petal"-like pattern in the stirring trajectory. In this embodiment, the aforementioned "petal"-like pattern is defined as a sub-trajectory. The distance between adjacent "petals" is measured by the number of adjacent sub-trajectories. The trajectory angle is equivalent to the angle formed between the axes of adjacent "petals," directly reflecting the distance between adjacent "petals." Therefore, the trajectory angle can be used as the most direct indicator of the stirring degree of the stirring trajectory. A farthest point adjacent to another farthest point constitutes the two farthest points of an adjacent "petal."

[0283] Specifically, given a fixed stirring trajectory, a higher number of sub-trajectories, fewer adjacent sub-trajectories, and a smaller trajectory angle result in a denser stirring trajectory and a lower degree of stirring. Conversely, fewer sub-trajectories, more adjacent sub-trajectories, and a larger trajectory angle result in a looser stirring trajectory and a larger stirring range. After obtaining the number of sub-trajectories, the number of adjacent sub-trajectories, and the trajectory angle based on the rotation speed ratio, the influence of these factors on the stirring trajectory can be used to determine the degree of stirring of the ingredients within the cookware 200 by the stirring trajectory formed by the current stirring head. This allows for the determination of the most suitable ingredients for cooking on the stir-fry machine to which the stirring head belongs.

[0284] However, in reality, the smaller the trajectory angle, the closer the adjacent sub-trajectories are, and the larger the trajectory angle, the farther the adjacent sub-trajectories are. Therefore, in one embodiment, only the trajectory angle is used to evaluate the degree of stirring, and the number of sub-trajectories and the number of adjacent sub-trajectories can be used as auxiliary understanding.

[0285] Furthermore, the ratio of the rotational speed to the revolutional speed and the trajectory angle satisfy the following formula: trajectory angle = 360° / (rotational speed / revolutional speed).

[0286] Specifically, the rotational speed / revolutionary speed actually represents the number of rotational cycles within one revolution cycle, which is equivalent to the number of rotations of the first stirring mechanism 13 while the second stirring mechanism 14 revolves once. Within each rotational cycle, the first blade of the first stirring mechanism 13 will deviate from the center of the pot by 200 degrees to its maximum value, i.e., the aforementioned farthest point. The trajectory angle defined above represents the number of times the maximum value occurs between two consecutive occurrences within one circumference, i.e., the number of times two adjacent farthest points occur; therefore, the above formula is used for calculation.

[0287] It is worth mentioning that, in the embodiments of the present invention:

[0288] When the angle between the two tracks is less than or equal to 180°, the resulting stirring track tends to gather the ingredients. That is, the combined rotation of the first stirring mechanism 13 and the second stirring mechanism 14 results in a gathering effect. The smaller the angle between the tracks, the greater the stirring degree, the worse the gathering effect, and the better the dispersing effect.

[0289] When the angle between the trajectories is greater than 180°, the resulting stirring trajectory tends to disperse the ingredients. That is, the combined rotation of the first stirring mechanism 13 and the second stirring mechanism 14 results in a dispersing effect. The larger the angle between the trajectories, the smaller the stirring degree, the worse the dispersing effect, and the better the gathering effect.

[0290] When the angle between the two tracks is close to 180°, the stirring degree is moderate, and the resulting stirring track has a good gathering and dispersing effect. That is, the joint rotation of the first stirring mechanism 13 and the second stirring mechanism 14 can both gather the ingredients and disperse them.

[0291] Example 12

[0292] Furthermore, the first rotational parameter includes the rotational speed of the first stirring mechanism 13, and the ratio of the rotational speed to the revolution speed is 1.2 to 30.

[0293] Specifically, by controlling the speed ratio within the aforementioned range, it is possible not only to control the speed of the first stirring mechanism 13 and the second stirring mechanism 14, allowing their speeds to be adjusted within a sufficiently large range to meet more acquisition needs, but also to output more types of stirring trajectories. Furthermore, it is possible to control the number of teeth of the first tooth unit and the second tooth unit. Since the number of teeth is directly related to the size of the first tooth unit and the second tooth unit, controlling the speed ratio within the aforementioned range also allows for the control of the size of the first tooth unit and the second tooth unit, thereby controlling the size of the stirring head 100 and the cooking device 1000.

[0294] Furthermore, the rotational speed of the first stirring mechanism 13 can be achieved through the following steps:

[0295] 1. Obtain the number of first teeth in the first tooth unit;

[0296] 2. Obtain the third rotational speed and the number of third teeth of the drive gear;

[0297] 3. Determine the first transmission relationship between the first tooth unit and the drive gear; and

[0298] 4. The rotational speed is obtained based on the first transmission relationship, the number of first teeth, the number of third teeth, and the third rotational speed.

[0299] Specifically, since the first tooth unit and the drive gear may not be directly connected, but there may be other transmission relationships, that is, there are other transmission gears between the first tooth unit and the drive gear. When the drive gear rotates, its third speed is constant, but after the transmission of other gears, that is, after the first transmission relationship, the rotation speed of the first tooth unit cannot be directly determined. Instead, it needs to be obtained by combining the number of first teeth, the third speed and the number of third teeth of the drive gear, and the first transmission relationship.

[0300] In the conversion law of rotational speed, the number of teeth of the driven gear is used as the denominator, and the number of teeth of the gear driving other gears is used as the numerator to obtain the proportional relationship. Finally, the proportional relationship needs to be multiplied by the third rotational speed of the driving gear to obtain the rotational speed of other gears and the rotational speed of the first tooth unit. If the transmission between multiple transmission gears is involved, the relationship between the multiple transmission gears needs to be clarified to obtain the transmission conversion formula.

[0301] For example, if the drive gear directly drives the first tooth unit to rotate, the speed ratio is the number of third teeth / the number of first teeth. Multiplying this by the speed of the drive gear will give the rotation speed of the first tooth unit.

[0302] Furthermore, the revolution speed of the second stirring mechanism 14 can be achieved through the following steps:

[0303] 1. Obtain the number of second teeth in the second tooth unit;

[0304] 2. Obtain the third rotational speed and the number of third teeth of the drive gear;

[0305] 3. Determine the second transmission relationship between the second gear unit and the drive gear; and

[0306] 4. The revolution speed is obtained based on the second transmission relationship, the number of the second teeth, the number of the third teeth, and the third rotational speed.

[0307] Specifically, since the second tooth unit and the drive gear may not be directly connected, but there may be other transmission relationships, that is, there are other transmission gears between the second tooth unit and the drive gear. When the drive gear rotates, its third speed is constant, but after the transmission of other gears, that is, after the second transmission relationship, the revolution speed of the second tooth unit cannot be directly determined. Instead, it needs to be obtained by combining the number of second teeth, the third speed and the number of third teeth of the drive gear, and the second transmission relationship.

[0308] In the conversion law of rotational speed, the number of teeth of the driven gear is used as the denominator, and the number of teeth of the gear driving other gears is used as the numerator to obtain the proportional relationship. Finally, the proportional relationship needs to be multiplied by the third rotational speed of the driving gear to obtain the rotational speed of the other gears. If the transmission between multiple gears is involved, the relationship between the multiple gears needs to be clarified to obtain the transmission conversion formula.

[0309] For example, if the drive gear directly drives the second tooth unit to rotate, the speed ratio is the number of third teeth / the number of second teeth. Multiplying this by the speed of the drive gear will give the revolution speed of the second tooth unit.

[0310] Furthermore, the step of determining the first transmission relationship between the first tooth unit and the drive gear includes the following steps:

[0311] Determine one or more first transmission gears used when driving the first gear unit, and the transmission relationship between the driving gear, one or more first transmission gears and the first gear unit;

[0312] Determine the first number of teeth of a first transmission gear or the multiple first transmission teeth of multiple first transmission gears;

[0313] One or more first transmission teeth are combined with a transmission relationship to form the first transmission relationship between the first tooth unit and the drive gear;

[0314] When there are multiple first transmission gears, the multiple first transmission gears may be the same or different, and the number of teeth of the multiple first transmission gears may be the same or different.

[0315] Specifically, in this embodiment of the invention, the first tooth unit and the drive gear are not directly connected, but there are other transmission relationships. That is, there are one or more first transmission gears between the first tooth unit and the drive gear. When the drive gear rotates, its third speed is constant. However, after the transmission of one or more first transmission gears, the rotation speed of the first tooth unit cannot be directly determined. Instead, it needs to be obtained by combining the number of first teeth, the third speed and the number of third teeth of the drive gear, and the number of one or more first transmission teeth.

[0316] In the conversion law of rotational speed, the number of teeth of the driven gear is used as the denominator, and the number of teeth of the gear driving other gears is used as the numerator to obtain the proportional relationship. If the first transmission gear drives the first gear unit to rotate, the proportional relationship is the number of teeth of the first transmission gear / the number of teeth of the first gear. If the first transmission gear also drives other first transmission gears, the proportional relationship must be increased by the number of teeth of the first transmission gear / the number of teeth of the first transmission gear. Finally, it needs to be multiplied by the rotational speed of the driving gear to obtain the rotational speed of the first gear unit.

[0317] Furthermore, the step of determining the second transmission relationship between the second gear and the drive gear includes the following steps:

[0318] Determine one or more second transmission gears used when the drive gear drives the second tooth unit, and the transmission relationship between the drive gear, one or more second transmission gears and the second tooth unit;

[0319] Determine the number of second transmission teeth of a second transmission gear or the number of second transmission teeth of multiple second transmission gears;

[0320] One or more second transmission teeth are combined with a transmission relationship to form a second transmission relationship between the second tooth unit and the drive gear.

[0321] When there are multiple second transmission gears, the multiple second transmission gears may be the same or different, and the number of teeth of the multiple second transmission gears may be the same or different.

[0322] Specifically, in this embodiment of the invention, the second tooth unit and the drive gear are not directly connected, but there are other transmission relationships. That is, there are one or more second transmission gears between the second tooth unit and the drive gear. When the drive gear rotates, its third speed is constant, but after the transmission of one or more second transmission gears, the revolution speed of the second tooth unit cannot be directly determined. Instead, it needs to be obtained by combining the number of second teeth, the third speed and the number of third teeth of the drive gear, and the number of one or more second transmission teeth.

[0323] In the conversion law of rotational speed, the number of teeth of the driven gear is used as the denominator, and the number of teeth of the gear driving other gears is used as the numerator to obtain the proportional relationship. If the second transmission gear drives the second gear unit to rotate, the proportional relationship is the number of teeth of the second transmission gear / the number of teeth of the second gear. If the second transmission gear also drives other second transmission gears, the proportional relationship must be increased by the number of teeth of the second transmission gear / the number of teeth of the second transmission gear. Finally, it needs to be multiplied by the rotational speed of the driving gear to obtain the revolution speed of the second gear unit.

[0324] Furthermore, the cooking device 1000 also includes a motor that drives the drive gear to rotate, obtains the motor speed, and uses the motor speed as the third speed of the drive gear.

[0325] Specifically, in this embodiment of the invention, the drive gear is directly connected to the motor to be driven to rotate. Therefore, the rotational speed of the drive gear is equal to the rotational speed of the motor. Obtaining the rotational speed of the drive gear is equivalent to obtaining the rotational speed of the motor. The rotational speed of the motor is used as the third rotational speed of the drive gear for calculation. Moreover, compared with directly obtaining the rotational speed of the drive gear, it is easier to obtain the rotational speed of the motor, and there is no need to set other mechanisms on the drive gear to detect its rotational speed.

[0326] Furthermore, when the rotational speed / revolutionary speed is an integer, the number of sub-trajectories is equal to the rotational speed / revolutionary speed, and the number of adjacent sub-trajectories is equal to 1;

[0327] When the rotational speed / revolutionary speed is a fraction, the number of sub-trajectories is equal to the numerator of the fraction, and the number of adjacent sub-trajectories is equal to the denominator of the fraction.

[0328] For example:

[0329] Please combine Figure 34 If the rotation speed / revolution speed = 5, that is, when the rotation speed / revolution speed = 5, the included angle is 360° / 5 = 72°, which means that the number of petals (sub-trajectories) in the stirring trajectory is 5, and the distance between two petals (sub-trajectories) is relatively close, which is equivalent to only the distance range of one petal (sub-trajectories). At this time, the included angle value is small, the stirring trajectory is not dense, the stirring degree is large, the gathering effect is poor (mainly because the second stirring angle of the second stirring mechanism 14 is large), and the dispersing effect is good.

[0330] Please combine Figure 35 If the rotation speed / revolution speed = 2.5 = 5 / 2, that is, when the rotation speed / revolution speed = 2.5 = 5 / 2, the included angle is 360° / 2.5 = 144°, which means that the number of petals (sub-trajectories) in the stirring trajectory is 5, and the distance between two petals (sub-trajectories) is the range of two petals (sub-trajectories). At this time, the value of the included angle is moderate, the density of the stirring trajectory is moderate, the stirring degree is moderate, the gathering effect is moderate, and the dispersing effect is moderate.

[0331] Please combine Figure 36 If the rotation speed / revolution speed = 1.667 = 5 / 3, then the included angle is 360° / 1.667 = 216°. This means that the number of petals (sub-trajectories) in the stirring trajectory is 5, and there is a distance of three petals (sub-trajectories) between two petals (sub-trajectories). At this time, the included angle is relatively large, the density of the stirring trajectory is moderate, the stirring degree is moderate, the gathering effect is moderate, and the dispersing effect is moderate.

[0332] Please combine Figure 37 If the rotation speed / revolution speed = 1.25 = 5 / 4, that is, the rotation speed / rotation-revolution = 1.25 = 5 / 4, the included angle is 360° / 1.25 = 288°, that is, the number of petals (sub-trajectories) in the stirring trajectory is 5, and there is a distance of four petals (sub-trajectories) between two petals (sub-trajectories). At this time, the included angle is larger, the stirring trajectory is not dense, the stirring degree is greater, the gathering effect is better (mainly because the second stirring angle of the second stirring mechanism 14 is smaller), and the dispersing effect is poor.

[0333] Please combine Figure 38The diagram shows the specific shapes of the stirring trajectories when the number of petals (sub-trajectories) in the stirring trajectory is 2, 3, 4, 7, 10, 12, and 15, and the included angles are 180°, 120°, 90°, 51.425°, 36°, 30°, and 24°, respectively. It clearly shows the actual change in the stirring trajectory caused by the adjustment of the rotation speed / revolution speed (i.e., the tooth ratio related to the first stirring mechanism 13 and the second stirring mechanism 14), reflecting the actual change in the degree of stirring of the ingredients.

[0334] In a preferred embodiment, the ratio of the rotational speed to the revolutional speed is 1.25 to 5.

[0335] Specifically, by controlling the speed ratio within the aforementioned range, it is possible not only to control the speed of the first stirring mechanism 13 and the second stirring mechanism 14, allowing their speeds to be adjusted within a suitable range to meet more acquisition needs, but also to output more types of stirring trajectories. Furthermore, it is possible to control the number of teeth of the first tooth unit and the second tooth unit. Since the number of teeth is directly related to the size of the first tooth unit and the second tooth unit, controlling the speed ratio within the aforementioned range also allows the size of the first tooth unit and the second tooth unit to be controlled within a suitable range, thereby controlling the size of the stirring head 100 and the cooking device 1000.

[0336] Example 13

[0337] Furthermore, the range of the trajectory angle is 30° to 330°.

[0338] Specifically, by combining and replacing the transmission gears between the motor, the first gear unit, and the second gear unit, the change and control of the obtained trajectory angle can be achieved, keeping the trajectory angle within the above range. The range of trajectory angles that can be formed is large enough, that is, there are enough different shapes of the stirring trajectory to meet the needs for obtaining more diverse stirring trajectories.

[0339] In practical applications of stirring trajectory and the angle between the trajectories, the stirring trajectory varies depending on the requirements of different dishes. For example, when cooking vegetables, a greater degree of stirring is required, and the trajectory angle is close to 180°; while when cooking braised pork or tofu, because these dishes require mixed sauces, a smaller degree of stirring is required, and the angle is close to 30°.

[0340] In a preferred embodiment, the trajectory angle ranges from 72° to 288°.

[0341] This avoids the problem of insufficient mixing and poor cooking results due to an overly dense mixing trajectory caused by an excessively small trajectory angle, while also preventing the problem of an overly sparse mixing trajectory caused by an excessively large trajectory angle, which would make it difficult to effectively mix all the ingredients within the pot 200. Furthermore, controlling the trajectory angle within the aforementioned optimal range can also meet most of the requirements for obtaining the mixing trajectory.

[0342] Example 14

[0343] Furthermore, please refer to Figure 39 The second rotation parameter also includes the second stirring angle of the second stirring mechanism. Step S5 includes the following steps:

[0344] S52: Adjust the second stirring angle of the second stirring mechanism according to the required information;

[0345] Step S6 also includes the following steps:

[0346] S62: Control the rotation of the second stirring mechanism according to the adjusted second stirring angle.

[0347] Specifically, in this embodiment of the invention, the second stirring angle is actually the angle between the second stirring mechanism 14 and the pot 200, and the angle between the connecting rod of the spatula connected to the second stirring mechanism 14 and the plane of the pot. The second stirring angle directly affects the coverage of the stirring trajectory formed by the second stirring mechanism 14 on the pot 200. Although it will not cause a huge change to the general outline of the stirring trajectory, it still has some influence.

[0348] Therefore, in addition to adjusting the second stirring mechanism 14 to adjust the specific form of the stirring trajectory, the stirring trajectory can also be adjusted by adjusting the second stirring angle of the second stirring mechanism 14 so that the stirring trajectory meets the acquisition requirements. For example, when more scraping and stirring of the food at the edge of the pot 200 is required, the second stirring angle can be increased so that the second stirring mechanism 14 is more inclined to scrape and stir the edge area of ​​the pot 200; when more scraping and stirring of the food at the edge area of ​​the pot 200 is not required, the second stirring angle can be decreased so that the second stirring mechanism 14 is more concentrated on scraping and stirring the middle area of ​​the pot 200.

[0349] Furthermore, please refer to Figure 40 The second stirring angle B is the angle formed by the vertical line between the second stirring mechanism 14 and the center point of the pot opening plane of the pot 200. Figure 40 This is an example of a second cooking device 1000 provided in an embodiment of the present invention. To determine the position and size of the second stirring angle B in two other cooking devices 1000, refer to... Figure 40 The label is sufficient.

[0350] Example 15

[0351] Furthermore, please refer to Figure 41 Step S1 further includes the following steps:

[0352] S13: Determine the second degree of stirring of the ingredients in the cookware 200; and

[0353] S14: Determine the requirement for obtaining the stirring trajectory of the cooking equipment based on the second stirring degree.

[0354] It is understandable that the shape of the stirring trajectory actually reflects the degree of stirring of the food in the cookware 200. Therefore, the need to obtain the stirring trajectory is actually based on the degree of stirring of the ingredients. Thus, if a user is cooking food using the cooking device 1000, the first degree of stirring of the ingredients is determined. This first degree of stirring is also affected by the second degree of stirring. Therefore, the need to obtain the stirring trajectory can be determined based on the second degree of stirring. In this embodiment of the invention, the need can be determined by determining either the first degree of stirring or the second degree of stirring.

[0355] For example, different levels of the second stirring degree can be pre-classified into different grades and stored in the controller of the cooking device 1000. When the current cooking device 1000 and its stirring head 100 are used, and the user selects a grade through the controller, the second stirring degree corresponding to the stirring head 100 and the cooking device 1000 can be determined according to the grade. This makes it convenient for the manager of the cooking device 1000 to use the cooking device to cook ingredients and dishes corresponding to its second stirring degree, so that the second stirring mechanism 13 outputs a stirring trajectory that meets the requirements, in order to achieve the best cooking effect.

[0356] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
