Description

Technical Field

[0001] The present application relates to the technical field of smart home appliances, and in particular to a cooking device and a cooking device control method. Background Art

[0002] With the development of artificial intelligence technology, more and more intelligent machines are applied to people's lives, such as intelligent cooking equipment. The stirring spatula in the intelligent cooking equipment is driven by a motor to rotate to stir the ingredients for stir-frying.

[0003] At present, the stirring spatulas in most smart cooking devices can only stir the ingredients horizontally, that is, the stirring spatulas can only rotate in the same horizontal plane. The stirring spatulas can only stir the ingredients horizontally, and the shape of the existing stirring spatulas is limited, which makes it easy for the ingredients to be stirred unevenly. In particular, for ingredients that are easy to clump, insufficient stirring will result in poor finished dishes. Summary of the invention

[0004] In order to improve the problem of uneven mixing of ingredients, the present application provides a cooking device and a cooking device control method.

[0005] In one embodiment of the present application, a cooking device is provided. The cooking device comprises:

[0006] an apparatus body having a cooking cavity;

[0007] A stirring assembly is located in the cooking cavity, the stirring assembly includes a stirring shaft and blades on the stirring shaft, the blades extend away from the stirring shaft and twist and gradually rise;

[0008] A driving assembly, disposed on the equipment body and connected to the stirring assembly;

[0009] The control device is connected to the driving component and is used to control the driving component to output rotational power and lifting power when the food in the cooking cavity needs to be turned over, so that the blades can be lifted and lowered while rotating, and the lifted blades during the rotation and lifting can turn over the lower food, so as to achieve horizontal stirring and up and down turning over at the same time; when turning over and over is not needed, the driving component is controlled to output rotational power.

[0010] In another embodiment of the present application, a cooking device control method is provided, which is applicable to the control device of the cooking device. The cooking device control method includes:

[0011] Determining whether the food in the cooking chamber of the cooking device needs to be stirred;

[0012] When stirring is required, the driving component of the cooking device is controlled to output rotational power and lifting power, so that the blades in the cooking cavity rotate and lift at the same time; wherein the blades are arranged on a stirring shaft connected to the driving component, and the blades extend far from the stirring shaft and twist and gradually lift up; during the rotation and lifting of the blades, the lifted blades flip up the lower part of the food, so as to achieve horizontal stirring and up and down stirring at the same time;

[0013] When stirring is not required, the driving assembly is controlled to output rotational power.

[0014] In the technical solutions provided by the embodiments of the present application, the blades in the stirring assembly extend far from the stirring axis and twist and gradually lift up. The shape of the blade twisting and gradually lifting up is conducive to the blade turning up the ingredients located at the bottom of the cooking cavity during the movement of rotation and / or lifting, so that the ingredients are turned over more thoroughly and the uniformity of the ingredients is improved. The control device of the cooking device is connected to the drive assembly, and when it is determined that the ingredients in the cooking cavity need to be turned over, the drive assembly is controlled to output the rotation power and the lifting power, so that the blades rotate and lift at the same time, and the blades gradually lift up during the rotation and lifting to turn up the lower ingredients, so as to achieve horizontal stirring and up and down stirring at the same time. This solution can control the internal blades to perform diversified movements (rotation and / or lifting) according to the different stirring requirements of the ingredients; for ingredients with stirring requirements (such as ingredients that are easy to form a mass), the blades are controlled to rotate and lift at the same time, so that the blades stir the ingredients at different horizontal planes and stir the ingredients up and down at the same time, which is conducive to the mixing of the ingredients in the cooking cavity, and ensures the adequacy of the stirring of the ingredients. From the above, this solution combines the structure of the blades and the motion control of the blades, optimizes the stirring performance of the cooking device, can achieve better cooking effects of ingredients, and the user has a better cooking experience.

[0022] In the current fast food era, smart cooking equipment (also known as smart food processors) has shown a functional and professional development trend. Smart cooking equipment can automatically stir ingredients, add seasonings, clean, etc. through its stirring components, peristaltic pumps and other components, which brings great convenience to users when cooking ingredients, and is therefore very popular among users. However, existing smart cooking equipment still has certain limitations in the automatic stirring function of ingredients. For example, most of the current smart cooking equipment controls the stirring spatula to stir the ingredients horizontally, and some ingredients are prone to clumping.

[0023] For example, dishes such as garlic sauce often have more liquid in the upper layer and more solid in the lower layer. When a mixing spatula can only stir the ingredients horizontally and cannot stir the ingredients up and down, dishes such as garlic sauce cannot achieve a good mixing effect, and the finished dish will not be good.

[0024] In order to solve the problem of uneven mixing of ingredients, the present application provides a cooking device and a cooking device control method. The cooking device described in the context of the present application, that is, the smart cooking device described above, is just described differently in different scenarios.

[0025] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0026] In some processes described in the specification, claims and the above-mentioned figures of the present application, multiple operations appearing in a specific order are included, and these operations may not be executed or executed in parallel in the order in which they appear in this article. The serial numbers of the operations, such as 101, 102, etc., are only used to distinguish different operations, and the serial numbers themselves do not represent any execution order. In addition, these processes may include more or fewer operations, and these operations may be executed in sequence or in parallel. It should be noted that the descriptions of "first", "second", etc. in this article are used to distinguish different messages, devices, modules, etc., do not represent the order of precedence, and do not limit "first" and "second" to different types. In addition, the embodiments described below are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.

[0027] Before introducing the method embodiment provided in the present application, the cooking device provided in the present application is first introduced in detail.

[0028] Figure 1a to Figure 1c The schematic diagram of the structure of the cooking device provided in the embodiment of the present application is shown. Figure 1a to Figure 1c As shown, the cooking device includes: an equipment body 1, a stirring component 12, a driving component 16, and a control device (not shown in the figure).

[0029] The device body 1 has a cooking cavity 110. The stirring assembly 12 is located in the cooking cavity, and the stirring assembly includes a stirring shaft 122 and blades 121 on the stirring shaft 122. The blades 121 extend away from the stirring shaft 122 and twist to gradually lift up. The driving assembly 16 is arranged on the device body 1 and connected to the stirring assembly. The control device (not shown in the figure) is connected to the driving assembly 16, and is used to control the driving assembly 16 to output rotational power and lifting power when the food in the cooking cavity needs to be turned over, so that the blades can be lifted and lowered while rotating, and the lifted blades during the rotation and lifting will turn over the lower food, so as to achieve horizontal stirring and flipping up and down at the same time; when flipping is not required, the driving assembly is controlled to output rotational power.

[0030] In addition to the above components, the cooking device may also include a pot body 11, a pot cover 15, and a base 13. The pot cover 15 covers the open part of the pot body 11 to form a cooking cavity 110. The base 13 is used to support the pot body 11 so that the pot body 11 can be stably placed on the base 13. The base 13 has a front side and a rear side relative to each other, and a display operation panel 131, a control switch 132, etc. may be provided on the front side. The interactive device (display operation panel) 131 is used for human-computer interaction, such as displaying information such as cooking steps to the user, allowing the user to select a digital recipe for the desired cooking, and allowing the user to configure the stirring method of the ingredients, etc. The control switch 132 can be used to input corresponding control instructions to the cooking device, wherein the operation method of the control switch 132 can be but not limited to: circumferential rotation, pressing, touching, etc. In addition, a heating component (not shown in the figure) is also provided between the front side and the rear side of the base 13, which is used to heat the ingredients in the cooking cavity when the pot body 11 is placed on the base 13 to cook the ingredients. In a specific implementation, the heating component may be, but is not limited to, an electromagnetic wire coil, which heats the food through the magnetic radiation it generates.

[0031] Further, the cooking device may also include: an arm assembly 14, which is used to provide support when the pot cover 15 is opened and closed. Specifically, the arm assembly 14 may include a cantilever 142 and a support arm 141. The support arm 141 is fixedly arranged on the rear side of the base 13. One end of the cantilever 142 is connected to the support arm 141, and the other end is connected to the pot cover 15, so that the pot cover 15 can be suspended above the base 13. The above-mentioned cantilever 142 can rotate relative to the support arm 141. As the cantilever 142 rotates relative to the support arm 141, the pot cover 15 approaches or moves away from the pot body, so that it is at least in a closed state or an open state. The pot cover 15 is in a closed state, which means that the pot cover covers the pot body and is in contact with the pot body. The pot cover 15 is in an open state, which means that the pot cover is not in contact with the pot body.

[0032] The stirring assembly 12 is disposed on the inner side of the pot cover 15. When the pot cover 15 is covered on the pot body 11, the stirring assembly 12 is located in the cooking cavity and can stir the food in the cooking cavity when cooking the food. Figure 2a The stirring assembly 12 is arranged on the inner side of the pot cover 15 through the connecting assembly 17. The connecting assembly 17 includes a transmission device 171, which is used to transmit the power output by the driving assembly 16 to the stirring assembly 12. The transmission device 171 may include a connecting hole 1711 and a transmission member 1712, the connecting hole 1711 is connected to the driving assembly 16, the transmission member 1712 rotates under the drive of the driving assembly 16, and the rotation of the transmission member 1712 can drive the stirring shaft in the stirring assembly 12 to rotate synchronously.

[0033] The stirring assembly 12 includes a stirring shaft 122 and a blade 121 on the stirring shaft 122. The blade 121 and the stirring shaft 122 are separate parts connected together, and the blade 121 is driven to rotate and / or rise and fall by the stirring shaft 122. Alternatively, the blade 121 and the stirring shaft 122 are an integrally formed structure. The material of the blade 121 and the stirring shaft can be the same or different.

[0034] In order to effectively improve the performance of the blade 121 in stirring the food, Figure 2a As shown, the blade 121 extends from the stirring shaft 122 to a distance and twists, so that the blade gradually rises. Specifically, the blade 121 extends from the stirring shaft 122 along the depth direction of the cooking cavity (i.e. Figure 2b The agitator shaft 122 extends in a horizontal direction and twists (as shown in the downward direction). Figure 2a The distal end of the blade is raised and shaped like a spade.

[0035] See also Figure 2b and 2c The blade 121 has a first edge 123 facing the cooking cavity wall and a second edge 124 facing the cooking cavity opening (or toward the pot cover 15). Figure 2c As shown, the stirring shaft 122 is the proximal end of the blade 121, and the end of the blade 121 away from the stirring shaft 121 is the distal end. The first edge 123 and the second edge 124 are connected at the distal end of the blade 121. The projection of the second edge 124 on the reference surface is an S-shaped or C-shaped curve; the projection of the first edge 123 on the reference surface is an arc, and the arc protrudes in the direction away from the second edge 124. The reference surface is perpendicular to the axis of the stirring shaft 122.

[0036] See also Figure 1c In the embodiment shown, the end of the first edge 123 of the blade 121 facing the cooking cavity wall is in a pointed shape. The pointed end is more likely to scoop up the food and play a role in stirring.

[0037] In some examples, the stirring shaft 122 may be provided with one blade 121 , two blades or more blades. In the case of two blades or more blades, the plurality of blades are provided along the circumference of the stirring shaft 122 .

[0038] The twisting directions of the plurality of blades may be the same or different. For example, the plurality of blades include at least one blade twisted in a first direction and at least one blade twisted in a second direction; the first direction and the second direction are opposite.

[0039] The torsion direction mentioned in this article is defined with reference to the rotation direction of the stirring shaft. Figure 2a and 2cIn the illustrated embodiment, two blades are disposed on the stirring shaft 122 , and the two blades may be an integrally formed structure. Figure 2d In another embodiment shown, three blades are disposed on the stirring shaft 122, and the three blades are evenly distributed along the circumference of the shaft, that is, the angle between two adjacent blades is 120 degrees. Figure 2a From the perspective shown, the leaves on the right side of the figure are twisted outward from the paper (i.e., twisted in the direction of the arrow). The leaves on the left side are twisted inward from the paper. Figure 2c In the top view shown, the lower blades are twisted and lifted to the left, and the upper blades are twisted and lifted to the right. The rotation direction of the stirring shaft 122 is used as a reference to define Figure 2c The reversal direction of the two blades in the structure shown is clockwise, that is, the twisting and lifting directions of the two blades are both on the side indicated by the clockwise direction in the figure. Figure 2d Similarly, in the stirring assembly shown, the three blades have the same twisting direction, which is clockwise.

[0040] Figure 2e Another structural embodiment of a stirring assembly is shown, in which three blades are arranged on the stirring shaft. With reference to the rotation direction of the stirring shaft 122, the torsion direction of the second blade and the third blade is the first direction (i.e., clockwise), and the torsion direction of the first blade is the second direction (i.e., counterclockwise); thus, when the driving assembly outputs the rotational power and lifting power in the first direction, the second blade and the third blade can play the role of stirring and turning; when the driving assembly outputs the rotational power and lifting power in the second direction, the first blade can play the role of stirring and turning.

[0041] Further, see Figure 2b In the embodiment shown, the end of the stirring shaft is provided with two blades of an integral structure. The middle part of the lower end (bottom end) of the two blades of the integral structure has a U-shaped depression. The two blades 121 extend and twist in two opposite directions from the middle part.

[0042] Furthermore, if Figure 1b The driving assembly 16 can be arranged on the cantilever 142 and is drivingly connected to the stirring assembly 12. The driving assembly 16 is used to output driving forces such as rotational power and lifting power to drive the stirring shaft in the stirring assembly 12 to rotate, thereby driving the blades on the stirring shaft to rotate and / or lift through the stirring shaft.

[0043] Specifically, Figure 1cThe driving assembly 16 includes a lifting device 161 and a rotating device 162. The lifting device 161 is used to output lifting power to drive the blade 121 to perform an upward or downward movement along the depth direction of the cooking cavity 110 through the stirring shaft 122. The rotating device 162 is used to output rotational power to drive the blade 121 to perform a positive rotational movement (such as a clockwise rotational movement) or a reverse rotational movement (such as a counterclockwise rotational movement) through the stirring shaft.

[0044] The lifting device 161 may include a first motor and a driving wheel mechanism. The first motor is connected to the driving wheel mechanism, and the driving wheel mechanism is connected to the stirring assembly 12. The first motor provides power for the rotation of the driving wheel mechanism to control the blade 121 on the stirring shaft to move upward or downward through the driving wheel mechanism. The driving wheel mechanism may be, but is not limited to, a cam mechanism.

[0045] The rotating device 162 may include a second motor and a transmission mechanism. The second motor is connected to the transmission mechanism, and the transmission mechanism is connected to the stirring assembly. The second motor provides power for the rotation of the transmission mechanism, and the blade 121 on the stirring shaft is controlled by the transmission mechanism to perform forward rotation or reverse rotation. The transmission mechanism may be composed of, but not limited to, gears, belts and other components.

[0046] It should be noted that, considering that one motor can also drive two kinds of motion (rotational motion and lifting motion), in order to reduce costs, the first motor and the second motor mentioned above in this embodiment may refer to the same motor. Of course, the first motor and the second motor may also refer to different motors, which is not limited in this embodiment.

[0047] The above-mentioned control device can be a device with data processing and control capabilities, such as a single-chip microcomputer, a microcontroller unit (MCU), a central processing unit (CPU), a processing chip based on a field programmable gate array (FPGA) or a complex programmable logic device (CPLD), etc., and this embodiment does not limit this. The specific implementation description of the control device controlling the drive component to output different types of driving forces (such as rotational power and / or lifting power) according to the requirements of food mixing will be described in detail in the method embodiment provided in the following text application, and will not be described in detail here.

[0048] The cooking device provided in the embodiment of the present application may be, but is not limited to, a cooking machine, a food processor, an electric rice cooker, a soymilk machine, an intelligent pressure cooker, a juicer, etc. The components included in different types of cooking devices are often different. For a description of other specific components that may be included in the cooking device, please refer to the existing relevant content.

[0049] In summary, the cooking device provided by the embodiment of the present application includes an equipment body with a cooking cavity, a stirring component, a driving component, and a control device. The stirring component is located in the cooking cavity, and includes a stirring shaft and blades on the stirring shaft. The blades extend far from the stirring shaft and twist so that the blades gradually lift up. The blades are designed to be twisted and gradually lifted up, which is conducive to the blades being able to effectively turn up the ingredients located at the bottom during the rotation and / or lifting and other movements, so that the ingredients are more thoroughly stirred and the uniformity of the stirring of the ingredients is improved. The above-mentioned driving component is arranged on the equipment body and connected to the stirring component; the control device is connected to the driving component, and when it is determined that the ingredients in the cooking cavity need to be stirred, it can control the driving component to output the rotational power and the lifting power at the same time, so that the blades rotate and lift at the same time, and the blades that are gradually lifted up during the rotation and lifting turn up the lower ingredients, realizing horizontal stirring and flipping up and down at the same time; when it is determined that no stirring is required, the driving component is controlled to output the rotational power. In this solution, the cooking device can control the blades to perform various movements (rotation and / or lifting) according to the different stirring requirements of the ingredients; for the ingredients that require stirring, the blades can be controlled to rotate and lift at the same time, so that the blades can stir the ingredients at different levels and stir the ingredients up and down at the same time, which is conducive to fully mixing the ingredients up and down and ensuring the adequacy of the stirring of the ingredients. Figure 3a and 3b The schematic diagram shown in FIG. 1 adopts the structure of the stirring assembly provided in this embodiment, and combines the driving assembly to output the rotational power and the lifting power, so that the blades can be lifted and lowered while rotating, as shown in FIG. Figure 3a The blades stir the ingredients at different levels during their descent, and when they reach the lowest height, they rotate and rise (e.g. Figure 3b As shown in the figure, the twisted and lifted blade structure brings up the bottom ingredients, achieving the effect of stirring and flipping. It can be seen that this solution optimizes the stirring performance of the cooking equipment, can achieve better cooking effects of ingredients, and users have a better cooking experience.

[0050] Figure 5 The flowchart of the cooking device control method provided by an embodiment of the present application is shown. The execution subject of the method is the control device of the cooking device. For details of the control device and other components that the cooking device may include, please refer to the relevant contents described in other embodiments of the above application. Figure 5 As shown, the cooking device control method provided in the embodiment of the present application includes the following steps:

[0051] 101. Determine whether the food in the cooking chamber of the cooking device needs to be stirred;

[0052] 102. When stirring is required, the driving component of the cooking device is controlled to output rotational power and lifting power, so that the blades in the cooking cavity rotate and lift at the same time; wherein, the blades are arranged on a stirring shaft connected to the driving component, and the blades extend far away from the stirring shaft and are twisted and gradually lifted up; the blades that are gradually lifted up during the rotation and lifting of the blades flip the lower ingredients up, thereby achieving horizontal stirring and flipping up and down at the same time.

[0053] 103. When stirring is not required, the driving assembly is controlled to output rotational power.

[0054] In order to ensure that the ingredients can achieve a better cooking effect, this embodiment will first analyze the stirring needs of different ingredients, so as to control the blades used to stir the ingredients to perform adaptive movements according to the stirring needs of the ingredients, such as rotation and / or lifting. Among them, the analysis of the stirring needs of the ingredients can be implemented based on but not limited to one or more of the following information: the recipe information corresponding to the ingredients, the shape of the ingredients during the cooking process and other information related to the ingredients, the stirring method pre-configured by the user, the interactive instructions issued by the user during the cooking process, etc. Based on this, in an achievable technical solution, the above 101 "determining whether the ingredients in the cooking chamber of the cooking device need to be stirred" can specifically include:

[0055] S1. Obtaining information related to the food in the cooking chamber; determining whether stirring is required according to the information; and / or

[0056] S2, obtaining the stirring mode configured by the user through the interactive device or the client on the cooking device; determining whether stirring is required according to the stirring mode configured by the user; and / or

[0057] S3, in response to an interactive operation triggered by a user during the cooking process of the cooking device, determining whether stirring is required according to the user's interactive indication.

[0058] In the above S1, when cooking ingredients according to the digital recipe selected by the user, the information related to the ingredients may be the corresponding recipe information. The user may select the digital recipe through the client or the interactive device on the cooking device. The cooking device may obtain the corresponding recipe information in different ways when the user selects the digital recipe in different ways.

[0059] For example, in response to a digital recipe selection operation triggered by a user, the client may search and obtain the corresponding recipe information from the digital recipe database based on the digital recipe identifier (such as the recipe name) selected by the user and transmit it to the cooking device; or, the digital recipe identifier selected by the user may be directly sent to the cooking device, and the cooking device may search and obtain the corresponding recipe information from the digital recipe database based on the digital recipe identifier.

[0060] For another example, in response to a digital recipe selection operation triggered by a user through an interactive device thereon, the cooking device may acquire corresponding recipe information from a digital recipe database based on a digital recipe identifier selected by the user.

[0061] For another example, when a cooking device is connected to the Internet, a user can obtain recipe information from the network side through an interactive device of the cooking device.

[0062] The recipe information may include but is not limited to at least one of the following: food information, seasoning information, cooking steps, cooking methods (such as stir-frying over high heat, slow cooking over low heat, etc.). Based on the food information and / or cooking methods, it may be determined whether the food in the cooking cavity needs to be stirred.

[0063] When a sensor for collecting the shape information of the food in the cooking cavity is installed on the cooking device, the food can be only stirred horizontally at the beginning of cooking, and the shape information of the food in the cooking cavity can be collected in real time through the sensor. When the food is determined to be clumped based on the shape information of the food, the food is turned over. That is, the information related to the food can also be the shape information of the food, and whether the food in the cooking cavity is clumped can be analyzed based on the shape information of the food, so as to determine whether it needs to be turned over.

[0064] Based on the above content, in a specific implementable solution, the above-mentioned information related to ingredients is the recipe information of dishes to be cooked by the cooking device; and accordingly, in the above-mentioned S1, "determining whether stirring is required according to the information" can be implemented by at least one of the following steps:

[0065] S11, determining whether the food is easy to clump according to the food information included in the recipe information; if it is easy to clump, determining that it needs to be stirred; otherwise, stirring is not required; and / or

[0066] S12: When the cooking method included in the recipe information indicates that stirring is required, determining that stirring is required; when the cooking method does not indicate that stirring is required, determining that stirring is not required.

[0067] In the above S11, it is possible to analyze whether ingredients that are easy to clump are included according to various ingredients needed to prepare the dish contained in the ingredient information, so as to determine whether to stir the dish according to the analysis result.

[0068] For example, the recipe information corresponding to egg fried rice includes the ingredients of rice, eggs, corn kernels, onions, etc. The rice is soft in texture and tends to clump together during frying, so it can be determined that it needs to be stirred.

[0069] For another example, the recipe information corresponding to green pepper and shredded pork includes green pepper, shredded pork, etc. Through analysis, it is determined that green pepper, shredded pork, etc. are not ingredients that easily form a mass, so it can be determined that there is no need to stir them.

[0070] In the above S12, the cooking method may refer to different techniques and means used when cooking food, and the cooking method may include but is not limited to stir-frying, frying, deep-frying, boiling, frying, braising, stewing, steaming, etc. Different cooking methods have different requirements for stirring the ingredients.

[0071] For example, if the cooking method is stir-frying over high heat, it is often indicated that the ingredients need to be stirred. If the cooking method is boiling, because boiling is a cooking method that often contains more liquid in the upper layer and more solid in the lower layer, in order to avoid sufficient mixing of solid and liquid and sticking to the pot, it is often indicated that the ingredients need to be stirred continuously.

[0072] For another example, if the cooking method is steaming, boiling, etc., it can be indicated that there is no need to stir the ingredients.

[0073] Furthermore, the above S1 may also include the following step:

[0074] S13. Determine the dish to be cooked according to the recipe information; and determine whether it needs to be stirred according to the dish.

[0075] In specific implementation, the determined dishes to be cooked can be compared and analyzed with pre-set dishes that are easy to form a ball. If the pre-set dishes that are easy to form a ball include the dish to be cooked, it is determined that the dish to be cooked needs to be stirred; otherwise, stirring is not required.

[0076] For example, if the dish to be cooked is garlic sauce, egg fried rice, or fried noodles, then it is determined that stirring is required.

[0077] In another specific implementable solution, the above-mentioned food-related information is food shape information collected by the sensor on the cooking device; and accordingly, the above-mentioned S1 "obtaining information related to the food in the cooking cavity, and determining whether to stir according to the information" can be implemented by the following steps:

[0078] S11', when cooking starts, controlling the driving assembly to output rotational power;

[0079] S12', during the cooking process, obtaining the food shape information of the food in the cooking cavity collected by the sensor;

[0080] S13', if the food shape information indicates that the food is clumped, then it is determined that stirring is required; otherwise, stirring is not required.

[0081] In a specific implementation, the above-mentioned sensor may be, but is not limited to, an image sensor. When cooking begins, only the drive assembly may be controlled to output rotational power, so that the blades in the cooking cavity perform forward and / or reverse rotational motions to stir the ingredients horizontally. Furthermore, during the cooking process, a related image recognition and analysis algorithm may be used to analyze the food image of the food in the cooking cavity collected by the sensor to obtain the food morphology information in the cooking cavity; if the food state information indicates that the food has clumped, it is determined that it needs to be turned over, and subsequently the drive assembly may be controlled to output rotational power while outputting lifting power. Conversely, if the food information indicates that the food has not clumped, there is no need to turn over, and the drive assembly may continue to be controlled to output only rotational power.

[0082] Furthermore, the above S1 may also include the following steps:

[0083] When it is determined according to the information related to the food that stirring is required, determining a control strategy of the driving component based on the information;

[0084] The control strategy includes: the rotation speed, direction, and steering switching timing of the rotary power, and the lifting speed and lifting switching timing of the lifting power.

[0085] In a specific implementation, when the information is recipe information of dishes to be cooked by a cooking device, the control strategy of the driving component can be determined based on the cooking steps, ingredient information, etc. contained in the recipe information.

[0086] For example, the recipe information for egg fried rice contains the following cooking steps:

[0087] Step 1: Prepare the ingredients: rice, diced ham, chopped green onion, egg liquid. Pour the rice into the egg liquid and mix well.

[0088] Step 2, put a proper amount of oil in the pot, turn to medium heat after the oil is hot, pour the rice soaked in egg liquid into the pot and stir continuously, specifically, change the stirring direction once every first time interval T1;

[0089] Step 3: After the stirring time reaches the second time T2, add diced ham into the pot and stir-fry evenly;

[0090] Step 4: After the stir-frying time reaches the third time T3, add salt, black pepper and other seasonings into the pot;

[0091] Step 5. Add chopped green onion into the pot, stir-fry for the fourth time T4 and then turn off the heat.

[0092] Based on the above cooking steps, the control strategy that can be determined is: the trigger condition of the rotational power is that the rice is poured into the pot, the direction of the rotational power is forward by default, and the direction is switched once every first time T1, and the speed of the rotational power is medium speed (which can be determined according to the size of the fire); the trigger condition of the lifting power is to detect that the horizontal stirring time reaches the second time T1 and diced ham is added to the pot, and the lifting speed of the lifting power is medium speed.

[0093] The lifting and lowering switching timing of the lifting power in the control strategy can be determined according to the food information. For example, based on the type and quantity of each food contained in the food information, combined with the size and shape of the pot, the highest position that the food can reach when placed in the pot is estimated; based on the highest position, the maximum height that the blade needs to rise relative to the pot is determined, and the minimum height that the blade can descend relative to the pot is obtained according to the default settings (see Figure 1c or Figure 3a As shown), the lifting and lowering switching timing can be determined according to the highest and lowest altitudes obtained above.

[0094] When the food-related information is food shape information collected by the sensor on the cooking device, further, the food agglomeration size, agglomeration quantity, etc. can be analyzed according to the food shape information to obtain the food agglomeration degree; according to the food agglomeration degree, the control strategy corresponding to the driving component is determined. Specifically, if the correspondence relationship information between the food degree and the control strategy is preset in advance, the control strategy corresponding to the determined food agglomeration degree can be obtained based on the correspondence relationship information. For example, the food agglomeration degree is divided into the following three levels: mild agglomeration, moderate agglomeration, and severe agglomeration (such as high viscosity of the food). If the food agglomeration degree is mild agglomeration, the corresponding control strategy may include: the rotation speed of the rotating power is V11, forward and reverse rotation, and a steering switch is performed once every first preset time interval, the lifting speed of the lifting power is V12, and the lifting switching timing is rising to the highest height H2 and descending to the lowest height H1.

[0095] It should be supplemented here that: some of the control strategies can also be determined in combination with pre-set information when they cannot be determined based on the corresponding information of the ingredients. For example, when the information related to the ingredients is the recipe information of the dishes that the cooking equipment needs to cook, the lifting and switching timing of the lifting power can also be determined according to the lifting range pre-set for the blades. In the above example given for the control strategy, the height difference between the highest height to which the blade can rise relative to the pot body and the lowest height to which the blade can descend relative to the pot body is the movement stroke A of the blade. And the lifting speed corresponding to the lifting power can be uniform or variable speed, etc. Variable speed means that the lifting speed is different at different times. For example, in the case of the lifting power output by the control drive component described later that makes the lifting amount and time relationship present a sinusoidal waveform relationship, the lifting speeds corresponding to different times are different, that is, the lifting speed corresponding to the lifting power is variable speed.

[0096] In the above S2, before using the cooking device to cook the ingredients, the user can use voice, touch, etc. to pre-configure the corresponding stirring mode for the ingredients to be cooked through the interactive device on the cooking device or the client, such as stirring only, stirring and stirring, and stirring only. When the stirring mode is configured by the user through the client, the client communicates with the cooking device, and the client can send the stirring mode configured by the user to the cooking device. According to the stirring mode configured by the user, it can be determined whether stirring is required.

[0097] In the above S3, during the cooking process, the user can trigger corresponding interactive operations through the interactive device on the cooking device or the client by voice, touch, etc. according to different cooking stages or food status. For example, when the food is found to be clumping, an interactive instruction to stir the food is triggered; or when the cooking step where new food needs to be added is reached, an interactive instruction to stop stirring is triggered, etc. Whether stirring is needed can be determined based on the user's interactive instruction.

[0098] The client mentioned above may be, but not limited to, a smart phone, a tablet, a laptop, a desktop computer, etc. The communication connection method between the client and the cooking device may be, but not limited to, Bluetooth, mobile network, WIFI, etc.

[0099] In the above 102, when it is determined that the food in the cooking cavity needs to be turned over, controlling the driving assembly of the cooking device to output the rotational power and the lifting power at the same time may specifically include any one of the following:

[0100] A1, controlling the driving assembly to output forward rotational power and upward power at the same time, and to output reverse rotational power and downward power at the same time; or

[0101] A2, controlling the driving assembly to output ascending power while alternately outputting forward and reverse rotational power, and to output descending power while alternately outputting forward and reverse rotational power; or

[0102] A3. Control the drive assembly to output forward rotational power while outputting ascending power and then descending power, so that the blades ascend from the middle height to the highest and then descend to the middle height; and output reverse rotational power while outputting descending power and then ascending power, so that the blades descend from the middle height to the lowest and then rise to the middle height.

[0103] A1 and A2 above describe that the initial height of the blade is positioned at Figure 1c or Figure 3a In the case of the lowest height shown, the specific implementation method of controlling the drive assembly to output the rotational power and the lifting power. Specifically,

[0104] In the above A1, the driving component is controlled to output forward rotational power and upward power at the same time, so that the blades can rise from the lowest height to the highest height and stop the upward movement; then the steering switch and the lifting switch are performed, and the driving component is controlled to output reverse rotational power and downward power at the same time, so that the blades can fall from the highest height to the lowest height and stop the downward movement.

[0105] In the above A2, the drive component is controlled to output rising power, that is, while the blades rise from the lowest height to the highest height, the drive component simultaneously outputs alternating forward and reverse rotational power; thereafter, steering switching and lifting switching are performed, and the drive component is controlled to output descending power, that is, while the blades descend from the highest height to the lowest height, the drive component simultaneously outputs alternating forward and reverse rotational power.

[0106] The above A3 describes that the blades always rotate in the forward direction when they rise from the middle height to the highest and then fall to the middle height; and the blades always rotate in the reverse direction when they fall from the middle height to the lowest and then rise to the middle height.

[0107] The reverse is also true, that is, when the blades rise from the middle height to the highest and then fall to the middle height, the blades always rotate in the forward direction; when the blades fall from the middle height to the lowest and then rise to the middle height, the blades always rotate in the forward direction.

[0108] It should be noted that the various heights of the blades (such as the lowest height, the middle height, the highest height, etc.) are all relative to the cooking cavity (pot body). In this embodiment, when the cooking device starts to cook food, the control device therein can first position the blades at a suitable height according to the amount of food in the cooking cavity, and then perform corresponding control operations on the drive assembly. For example, if the amount of food in the cooking cavity is relatively small, the initial height of the blades can be set at Figure 1c or Figure 3aIf the amount of food in the cooking cavity is relatively large, the initial height of the blades can be set at an intermediate height. Also, when it is determined that the food in the cooking cavity needs to be stirred, if a control strategy of the drive component is further determined, the above 102 can be triggered according to the control strategy; if the control strategy of the drive component is not further determined, the above 102 can be triggered according to the preset control information.

[0109] Furthermore, the lifting power mentioned above may be a lifting power in which the lifting amount and time have a sinusoidal relationship. Assuming that the initial height of the blade is set at an intermediate height, the lifting power may make the lifting motion trajectory of the blade in the cooking cavity be as follows: Figure 4 The sinusoidal waveform shown in Figure 4 The sine waveform shown in is: f(x) = (A / 2) * sin x, A represents the lifting motion stroke of the blade (the height difference between the highest height and the lowest height), and x represents time. If the lifting device in the drive assembly includes a cam mechanism, A is related to the stroke of the cam in the cam mechanism. For example, A is the stroke of the cam.

[0110] Based on this, the above-mentioned “controlling the driving component to output lifting power” in 102 may specifically include:

[0111] The driving component is controlled to output a lifting power whose lifting amount and time have a sinusoidal waveform relationship.

[0112] In the case of a lifting power in which the lifting amount output by the driving component and the time have a sinusoidal relationship, the blades can be made to perform lifting and lowering motions at different speeds in different time periods based on the slope of the sinusoidal waveform corresponding to the lifting and lowering power in different time periods; wherein, the greater the slope, the faster the blades perform lifting and lowering motions, and the faster the speed of stirring the food.

[0113] As can be seen from the above content, when it is determined that the food in the cooking cavity needs to be stirred, the blades in the cooking cavity can be made to rotate and rise and fall at the same time by controlling the driving component to output the rotational power and the lifting power. Figure 3a and Figure 3b As shown, during the process of the blades rotating and rising and falling, the twisted and lifted structure of the blades can push the lower food 18 (more specifically food 181) upward, so that the lower food is turned up, thereby achieving horizontal stirring of the food on different horizontal planes while turning the food up and down, ensuring that the food in the cooking cavity is fully mixed up and down.

[0114] In the above 103, when it is determined that there is no need to stir the ingredients, the driving component can be controlled to output a single rotational force so that the blades in the cooking cavity only rotate, thereby achieving horizontal stirring of the ingredients in the cooking cavity on the same horizontal plane.

[0115] In summary, the technical solution provided by this embodiment will first determine whether the ingredients in the cooking cavity of the cooking device need to be turned over, and then control the driving component of the cooking device according to the determination result. Specifically, when it is determined that turning over is required, the driving component will be controlled to output the rotational power and the lifting power at the same time, so that the blades in the cooking cavity rotate and lift at the same time. The above-mentioned blades are arranged on a stirring shaft connected to the driving component, and the blades extend far away from the stirring shaft and twist, so that the blades are gradually lifted up; the blades that are gradually lifted up during the rotation and lifting of the blades turn over the lower ingredients, and realize horizontal stirring and up and down stirring at the same time. When it is determined that turning over is not required, the driving component is controlled to output the rotational power to only realize horizontal stirring of the ingredients. It can be seen that in this scheme, the cooking device can control the internal blades to perform various movements (rotation and / or lifting) according to the different turning over requirements of the ingredients; for the ingredients with turning over requirements, by controlling the blades to rotate and lift at the same time, the blades can stir the ingredients at different horizontal planes and turn the ingredients up and down at the same time, which is conducive to fully mixing the ingredients up and down, and ensuring the adequacy of the turning over of the ingredients. In addition, the present solution designs the blades to twist and gradually lift up, which is beneficial for the blades to effectively turn up the food at the bottom during the rotation and / or lifting and other movements, so that the food can be turned over more thoroughly. As described above, the present solution optimizes the stirring performance of the cooking equipment, can achieve better food cooking effects, and users have a better cooking experience.

[0116] The above-mentioned cooking device control method provided in this embodiment can be briefly described as follows: Figure 6 When cooking starts, the cooking device can send a stirring command to the driving component to control the driving component to only output rotational power, so that the blades rotate forward and backward to achieve horizontal stirring of the ingredients in the cooking cavity; then, determine whether the ingredients in the cooking cavity need to be flipped; if not, continue to control the driving component to only output rotational power, so that the blades only rotate forward and backward at the same height (i.e., the same horizontal plane). If necessary, control the driving component to output both rotational power and lifting power, so that the blades rotate forward and backward while lifting up and down, so as to achieve horizontal stirring of the ingredients in the cooking cavity while flipping the ingredients up and down.

[0117] The technical solutions provided in each embodiment of the present application are described below in conjunction with specific application scenarios.

[0118] Scenario 1:

[0119] When a user uses a cooking device such as a cooking machine to cook dishes that are easy to form a clumping mass, such as egg fried rice, the cooking device responds to the user's cooking instructions and starts to cook the ingredients placed in the cooking cavity. The stirring function can be activated first, and the rotating device in the driving assembly inside the cooking device can be controlled to alternately output forward and reverse rotating power, so that the blades in the cooking cavity perform forward and reverse rotating motions to stir the ingredients in the cooking cavity horizontally. When the user sees that the ingredients are clumping, the user can trigger a flipping instruction through the interactive device on the cooking machine, or the control device of the cooking machine triggers a flipping instruction when determining that the ingredients are clumping based on the detection information of the sensor, and the control device controls the driving device to output the rotating power and the lifting power at the same time, so that the blades perform lifting motions along the depth direction of the cooking cavity while performing forward and reverse rotating power, thereby stirring the ingredients horizontally and flipping the ingredients up and down at the same time.

[0120] Scene 2:

[0121] The user selects the dish to be cooked, such as garlic sauce, through the interactive device of the cooking device, and puts the corresponding minced garlic and other ingredients into the pot. After starting cooking, the cooking device determines that the ingredients in the cooking cavity need to be stirred according to the dish (garlic sauce) selected by the user. At this time, the cooking device responds to the cooking start operation triggered by the user, and starts the stirring and stirring functions at the same time, controls the driving component to alternately output forward and reverse rotation power while outputting lifting power, so that the blade performs forward and reverse rotation power while performing lifting and lowering motion along the depth direction of the cooking cavity, thereby stirring the ingredients horizontally while stirring the ingredients up and down.
