[0070] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0071] The main solution of the embodiment of the present invention is: the cooking device includes a stirring component, a stirring motor, a seal and a pot body, the stirring component is located in the pot body, a through hole is provided at the bottom of the pot body, one end of the stirring component is passed through the through hole and is transmission-connected to the stirring motor, the stirring component is connected to the through hole through a seal, and the control method of the cooking device includes the following steps: obtaining a target angle for the stirring component to rotate, the target angle is less than a set angle threshold; controlling the stirring component to rotate within the target angle, the stirring component being used to stir the food in the pot body when rotating.

[0072] In the prior art, in cooking equipment, the stirring assembly located in the pot body is generally connected to its driving stirring motor by means of an inner pot through-shaft, and a seal needs to be provided between the inner pot and the stirring assembly. However, the seal is prone to aging and wear in a rotating friction environment, resulting in sealing failure.

[0073] The present invention provides the above-mentioned solution, aiming to reduce the wear of the sealing member, ensure the sealing performance of the pot body during the stirring process, and improve the reliability of the stirring control.

[0074] The embodiment of the present invention provides a cooking device. The cooking device here specifically refers to a device that can cook food by heating. Specifically, the cooking device can be an electric pressure cooker, an electric rice cooker, an oven, a microwave oven, etc.

[0075] In the embodiment of the present invention, refer to Figure 1 and Figure 2 The cooking device comprises a pot body 1, a stirring component 2, a stirring motor 3, a sealing member 4 and a control device. The stirring component 2 is located in the pot body 1, a first through hole is provided at the bottom of the pot body 1, one end of the stirring component 2 is passed through the first through hole and is transmission-connected to the stirring motor 3, and the stirring component 2 is connected to the first through hole through the sealing member 4. The stirring motor 3 is connected to the control device.

[0076] Specifically, in the present embodiment, the stirring assembly 2 specifically includes a stirring shaft 21 and a stirring blade 22. The stirring blade 22 is located in the pot body 1, the stirring shaft 21 is passed through a first through hole at the bottom of the pot body 1, one end of the stirring shaft 21 is located in the pot body 1 and is fixedly connected to the stirring blade 22, and the other end of the stirring shaft 21 is transmission-connected to the stirring motor 3. When the stirring motor 3 is turned on, the stirring shaft 21 can be driven to rotate, so as to drive the stirring blade 22 to stir the food in the pot body 1. Specifically, when the stirring motor 3 is running forward, the stirring shaft 21 can rotate in a first direction, and when the stirring motor 3 is running reversely, the stirring shaft 21 can rotate in a second direction, wherein the first direction is opposite to the second direction. Among them, the start, stop, direction, speed, etc. of the stirring motor 3 can be controlled by the control device connected thereto.

[0077] The number of stirring blades 22 can be set according to actual needs, and can be one, two, three or more. Specifically, when the number of stirring blades 22 is more than one, more than one stirring blades 22 are set at an angle, and the angles between adjacent stirring blades 22 can be set to be the same or different according to actual needs. Specifically, in this embodiment, the angles between adjacent stirring blades 22 are the same.

[0078] The sealing member 4 is disposed between the pot body 1 and the stirring assembly 2 . The sealing member 4 can be disposed inside, outside or in the first through hole of the pot body 1 according to actual needs.

[0079] In this embodiment, the stirring assembly 2 in the pot body 1 can stir the food in the pot, so that the nutrients of the food are fully released or the food is evenly colored, thereby improving the cooking effect of the cooking device. On this basis, a sealing member 4 is provided between the pot body 1 and the stirring assembly 2, so that the food in the pot body 1 can be prevented from leaking from the first through hole at the bottom of the pot body 1 to the outside of the pot body 1 during the stirring process, thereby achieving effective sealing of the pot body 1 during the stirring process.

[0080] Further, in this embodiment, referring to Figure 2 The seal 4 includes a first sealing segment 41, a second sealing segment 42 and a flexible segment 43 connecting the first sealing segment 41 and the second sealing segment 42. The first sealing segment 41 is fixedly connected to the stirring assembly 2, and the second sealing segment 42 is fixedly connected to the pot body 1. Specifically, the first sealing segment 41 is connected to the stirring shaft 21 in the stirring assembly 2. The flexible segment 43 is specifically made of a flexible material (such as resin, fiber, etc.). When the stirring shaft 21 rotates, the first sealing segment 41 will rotate with the stirring shaft 21. Since the first sealing segment 41 is fixed on the stirring shaft 21 and the second sealing segment 42 is fixed on the pot body 1, the two ends of the seal 4 can be tightly connected to the stirring shaft 21 and the pot body 1 to ensure the sealing of the stirring assembly 2 installed in the pot body 1. In addition, the flexible section 43 will rotate with the stirring shaft 21 and undergo flexible twisting, while the first sealing section 41 and the second sealing section 42 are fixed relative to the stirring shaft 21. Since the flexible section 43 is more flexible, it has better fatigue resistance during twisting, thereby effectively avoiding the wear of the seal 4 during the stirring process, and ensuring the sealing of the pot body 1, preventing food from leaking from the first through hole to the outside of the pot body 1, and ensuring zero leakage of the pot body 1 during the stirring process. Among them, when the stirring shaft 21 reciprocates between the forward and reverse directions, the flexible section 43 can switch between the tensioned and relaxed states, and no sliding friction will be generated between the seal 4 and the stirring shaft 21, thereby further avoiding the wear of the seal 4 during the rotation process.

[0081] Further, see Figure 1The cooking device also includes a shell 5, and the pot body 1 and the stirring motor 3 are both installed in the shell 5. Specifically, the stirring motor 3 can be fixed to the bottom of the shell 5 by a motor bracket 6. The pot body 1 is detachably connected to the shell 5. When the pot body 1 is separated from the shell 5, the stirring component 2 in the pot body 1 is separated from the stirring motor 3; when the pot body 1 is placed in the shell 5, the stirring component 2 in the pot body 1 is connected to the stirring motor 3. Here, the motor bracket 6 can be specifically an aluminum bracket, which can have functions such as magnetic isolation and waterproofing. It should be noted that the pot body 1 can be taken out of the shell 5 or put into the shell 5 according to the actual needs of the user. Only when the pot body 1 is in the shell 5, the control device will perform cooking operations or stirring operations.

[0082] Specifically, refer to Figure 3 , a marking portion 9 may be provided on the stirring component 2 (such as the stirring shaft 21) or the output shaft of the stirring motor 3, which is used to mark the rotation position of the stirring component 2, and the marking portion 9 has different positions when the stirring component 2 rotates. The central axis of the stirring component 2 is defined as its rotation axis a. Specifically, when the marking portion 9 is provided on the stirring component 2, the rotation axis a is the center line of the stirring shaft 21, and the marking portion 9 is provided on the outer wall of the stirring shaft 21. When the marking portion 9 is provided on the output shaft of the motor, the rotation axis a is the center line of the motor output shaft, and the marking portion 9 is located on the outer wall of the stirring shaft 21. The specific type of the marking portion 9 can be set according to actual needs, and a detection module 7 that cooperates with the marking portion 9 can be provided in the cooking device. The detection module 7 can be used to detect the position of the marking portion 9 to detect the rotation position of the stirring component 2. The detection module 7 can be specifically connected to the control device so that the control device obtains the current position of the stirring component 2 based on the detection signal of the detection module 7. The number of the detection modules 7 can be set according to actual needs (such as its detection range, the size of the target angle, etc.), and can be one, two, three, four or more.

[0083] In the present embodiment, the identification part 9 is a signal module matched with the detection module 7, and the detection module 7 can detect the signal generated by the signal module to realize the positioning of the current rotation position of the stirring component 2. Specifically, the signal generated by the signal module can be a color signal, a light signal, an infrared signal, etc., and the detection module 7 is a corresponding signal detection module. For example, when the signal module generates a color signal, the detection module 7 is a shooting module; when the signal module generates a light signal, the detection module 7 is a photosensitive sensor; when the signal module generates an infrared signal, the detection module 7 is an infrared receiver. In the present embodiment, the signal module is a magnetic part, and the detection module 7 is a magnetic sensor. The magnetic part can generate a magnetic signal. The magnetic sensor can determine the position of the identification part 9 by detecting the magnetic signal, thereby obtaining the rotation position of the stirring component 2.

[0084] Further, in this embodiment, referring to Figure 3The cooking device includes at least two detection modules 7, which are spaced apart and fixed in the housing 5, and each detection module 7 corresponds to a preset position of the identification portion 9. Specifically, the detection area of ​​each detection module 7 at least covers the corresponding preset position.

[0085] The preset position is specifically a default position selected in advance from a set of positions that can be reached by the identification portion 9. The number of preset positions is at least two, and the specific number may be the same as the number of detection modules 7, or may be less than the number of detection modules 7, that is, there may be a situation where one preset position corresponds to more than one detection module 7. For example, when at least two detection modules 7 include a first module and a second module, at least two preset positions may include a first position corresponding to the first module and a second position corresponding to the second module; for another example, when at least two detection modules 7 include a first module, a second module, a third module, and a fourth module, at least two preset positions may include a first position and a second position, wherein the first module and the second module are both set corresponding to the first position, and the third module and the fourth module are both set corresponding to the second position.

[0086] Define the line connecting the preset position and the rotating shaft a of the stirring component 2 as the reference line, then the maximum angle formed by at least two reference lines is less than or equal to 360 degrees. Specifically, in the present embodiment, the maximum angle formed by at least two reference lines is less than or equal to 180 degrees. The specific value of the maximum angle here can be set according to actual needs. In the present embodiment, the maximum angle here is set according to the target swing angle corresponding to the stirring blade 22. Specifically, when the number of stirring blades 22 is at least two, the target swing angle can be determined based on the angle between the stirring blades 22.

[0087] In this embodiment, the detection area of ​​each detection module 7 may be limited to covering the preset position corresponding to it, but not covering other preset positions. Based on this, if any detection module 7 detects the signal generated by the signal module, it can be considered that the stirring component 2 is located at the preset position corresponding to the detection module 7; if any detection module 7 does not detect the signal generated by the signal module, it can be considered that the stirring component 2 is located at a position other than the preset position corresponding to the detection module 7.

[0088] The number of the at least two detection modules 7 can be two, three or more according to actual needs. Specifically, the at least two detection modules 7 are arranged around the rotating shaft a corresponding to the stirring component 2 .

[0089] Specifically, in this embodiment, refer to Figure 3, at least two preset positions include a first preset position X and a second preset position Z, then at least two detection modules 7 include a first detection module 71 and a second detection module 72. The first detection module 71 corresponds to the first preset position X, and the second detection module 72 corresponds to the second preset position Z. Define the line connecting the rotation axis a of the stirring component 2 and the first detection module 71 as the fourth reference line, define the line connecting the rotation axis a and the second detection module 72 as the fifth reference line, define the line connecting the first preset position X and the rotation axis a of the stirring component 2 as the first reference line, define the line connecting the second preset position Z and the rotation axis a of the stirring component 2 as the second reference line, the first reference line and the fourth reference line are collinearly arranged, and the second reference line and the fifth reference line are collinearly arranged. Among them, the angle between the fourth reference line and the fifth reference line is the target angle of rotation of the stirring component 2, and the target angle is less than the set angle threshold, so that based on the signal detection of the first detection module 71 and the second detection module 72, the stirring component 2 is limited to rotate within a smaller target angle.

[0090] Further, see Figure 3 , at least two preset positions include a third preset position Y in addition to the first preset position X and the second preset position Z, and at least two detection modules 7 include a third detection module 73 in addition to the first detection module 71 and the second detection module 72. Based on this, the line connecting the third detection module 73 and the rotating shaft a is defined as the sixth reference line, and the sixth reference line is located between the fourth reference line and the fifth reference line. Wherein, when the signal module is located at the third preset position Y, the flexible section 43 of the seal 4 is in a completely relaxed state, that is, the torsional force is less than the set threshold value (such as 0), and the farther the signal module is from the third preset position Y, the greater the torsional force on the seal 4. Specifically, the line connecting the third preset position Y and the rotating shaft a of the stirring assembly 2 is defined as the third reference line, and the third reference line and the sixth reference line are collinearly arranged. In this embodiment, the sixth reference line is the angular bisector of the fourth reference line and the fifth reference line. In other embodiments, the sixth reference line can also be set to other positions between the fourth reference line and the fifth reference line according to actual needs.

[0091] The third preset position Y can be used to calibrate the initial position of the stirring component 2. When stirring starts, the third detection module 73 can detect the current rotation position of the stirring component 2 using the signal generated by the signal module. Further stirring operation is started only when it is determined that the signal module of the stirring component 2 is currently located at the third preset position Y based on the signal detected by the third detection module 73, thereby ensuring the accuracy of position control during the rotation process of the stirring component 2.

[0092] Further, in this embodiment, referring to Figure 1 The cooking device also includes a heating component 8, which is used to heat the pot body 1.

[0093] In the present embodiment, the heating assembly 8 is arranged below the pot body 1. In addition, in other embodiments, the heating assembly 8 can also be arranged on the side of the pot body 1 or surround the entire outer wall of the pot body 1. The heating assembly 82 includes a coil assembly, which generates heat to heat the pot body 1 when the coil assembly is powered on; and stops heating the pot body 1 when the coil assembly is powered off. Specifically, in the present embodiment, the heating assembly 8 also includes a mounting seat, which is located at the bottom of the pot body 1, and the mounting seat is formed with a mounting groove, and the coil assembly is arranged in the mounting groove and is spaced apart from the pot body 1. The mounting seat is fixed above the motor bracket 6, and the pot body 1 is detachably arranged above the mounting seat. A mounting platform is provided in the middle of the mounting seat, and the mounting groove forms the four sides of the mounting platform. A second through hole is formed on the mounting platform, and the output shaft of the stirring motor 3 can be passed through the second through hole and connected to one end of the stirring assembly 2 passed through the first through hole.

[0094] In the embodiment of the present invention, refer to Figure 4 , the above-mentioned stirring motor 3, heating component 8, and detection module 7 are all connected to the control device. The control device can control the operation of the stirring motor 3 and the heating component 8, and can also obtain the detection parameters of the detection module 7. The control device includes: a processor 1001 (such as a CPU), a memory 1002, etc. The processor 1001 is connected to the memory 1002 via a communication bus. The memory 1002 can be a high-speed RAM memory, or it can be a stable memory (non-volatile memory), such as a disk storage. The memory 1002 can optionally be a storage device independent of the aforementioned processor 1001.

[0095] Those skilled in the art will understand that Figure 4 The device structure shown in the figure does not constitute a limitation of the device, and may include more or less components than shown in the figure, or combine certain components, or arrange the components differently.

[0096] like Figure 4 As shown, the memory 1002 as a computer-readable storage medium may include a control program of the cooking device. Figure 4 In the device shown, the processor 1001 can be used to call the control program of the cooking device stored in the memory 1002, and execute the relevant step operations of the control method of the cooking device in the following embodiment.

[0097] The embodiment of the present invention further provides a cooking device control method for controlling the operation of the cooking device.

[0098] Reference Figure 5 , an embodiment of a control method of the cooking device of the present application is proposed. In this embodiment, based on the above-mentioned cooking device including a pot body, a stirring component, a stirring motor and a sealing member, the control method of the cooking device includes:

[0099] Step S10, obtaining a target angle of rotation of the stirring component, the target angle being less than a set angle threshold;

[0100] The stirring component has a rotating shaft during rotation, and a positioning point on the stirring component or on the output shaft of the motor that drives the stirring component and is spaced from the rotating shaft is defined as the identification part of the stirring component. The target angle is the target value that needs to be reached by the rotation angle formed by the identification part with the rotating shaft as the rotation center during rotation.

[0101] The target angle is less than the set angle threshold, indicating that the rotation angle of the stirring component is a smaller angle that does not exceed the set angle threshold. The set angle threshold can be set by the user, or it can be based on a parameter determined by the stirring characteristic parameters of the stirring component, or it can be based on a parameter determined by the current cooking characteristic parameters of the cooking device. In the present embodiment, the set angle threshold is 360 degrees, based on which the target angle of rotation of the stirring component is less than 360 degrees. In another embodiment, the set angle threshold can also be 180 degrees, based on which the target angle of rotation of the stirring component is less than 180 degrees. In addition, in other embodiments, the set angle threshold can also be set to other angles such as 270 degrees, 120 degrees, 150 degrees, 210 degrees, etc. according to actual needs.

[0102] Within the angle range less than the set angle threshold, one can be randomly selected or selected according to a preset rule as the target angle. Specifically, the specific value of the target angle can be set according to actual needs, and can be a parameter set by the user or a parameter determined based on the stirring characteristic parameters of the stirring component.

[0103] Step S20, controlling the stirring component to rotate within a target angle, wherein the stirring component is used to stir the food in the pot body while rotating.

[0104] Specifically, the stirring angle of the stirring component is controlled to be limited within a target angle by controlling the operating parameters (such as rotation speed, direction, etc.) of the stirring motor.

[0105] The stirring component can rotate unidirectionally or reciprocatingly within the target angle. Specifically, when the rotation angle of the stirring component reaches the target angle during its rotation, the stirring component can stop rotating or rotate in the reverse direction.

[0106] Among them, the rotation of the stirring component within the target angle can be restricted by a pre-set fixed position. For example, the target angle corresponds to two preset positions of the identification part, and the angle formed by the two preset positions and the rotating shaft of the stirring component is the target angle. The stirring component can be restricted to rotate within the range corresponding to the two preset positions to achieve that the rotation angle of the stirring component does not exceed the target angle.

[0107] In addition, the stirring component rotates within the target angle, and the target rotation parameters of the corresponding stirring component can also be determined based on the target angle. On this basis, by detecting its rotation characteristic parameters (such as the position of the identification part, the rotation speed, and the rotation duration) in real time during the rotation of the stirring component, when the rotation characteristic parameters match the target rotation parameters, it can be considered that the stirring component has reached the target angle, and the stirring component can be controlled to stop rotating or reciprocate. Among them, the starting time of the rotation characteristic parameter detection can be the time when the setting instruction is received, the current time, or the time when the identification part of the stirring component rotates to the set position.

[0108] A control method for a cooking device is proposed in an embodiment of the present invention. The method controls a stirring component to rotate within a target angle less than a set angle threshold to stir food in a pot. By limiting the torsion angle of the stirring component, it is avoided that the torsion angle of the stirring component is too large to cause damage to the seal or excessive fatigue and damage, thereby reducing the wear of the seal, ensuring the sealing of the pot during the stirring process, and improving the reliability of the stirring control.

[0109] Further, in this embodiment, the stirring assembly includes a stirring shaft and at least two stirring blades, and the at least two stirring blades are arranged at an angle to the stirring shaft. Figure 6 , step S10 comprises:

[0110] Step S11, obtaining a target swing angle corresponding to the stirring blade; the target swing angle is less than a set angle threshold;

[0111] The target swing angle here is specifically the target value of the swing angle of a single stirring blade during the rotation of the stirring assembly. When the number of stirring blades is more than one and the more than one stirring blades are not evenly distributed, the swing angle required for each stirring blade can be obtained, and the largest one of the more than one swing angles obtained is determined as the target swing angle.

[0112] The target swing angle may be a parameter set by the user, or may be an angle determined based on the current cooking characteristic parameters of the cooking device, or may be an angle determined based on the stirring characteristic parameters of the stirring component. For example, different types of cooked food may correspond to different target swing angles, and different types of cooking operations may correspond to different target swing angles.

[0113] Step S12, determining the target angle according to the target swing angle, wherein the target angle is greater than or equal to the target swing angle.

[0114] Specifically, among all angle values ​​greater than or equal to the target swing angle, an angle less than the set angle threshold can be arbitrarily selected as the target angle, or a setting parameter input by a user can be obtained, and an angle less than the set angle threshold can be selected as the target angle based on the setting parameter of the user, or an angle less than the set angle threshold can be selected as the target angle based on the cooking characteristic parameters of the current cooking device (such as the cooking operation type and / or the cooking food type). For example, when the cooking food type is solid, its target angle can be greater than the target angle when the cooking food type is liquid.

[0115] Here, the target angle is determined through steps S11 to S12 to ensure that the rotation of the stirring component is limited within the target angle to meet the operating requirements of its stirring blades. While limiting the torsion angle of the stirring component to reduce the wear of the seal, it can also ensure that the rotation of the stirring component can meet the stirring requirements required for cooking.

[0116] Furthermore, in this embodiment, the step of obtaining the target swing angle corresponding to the stirring blade includes:

[0117] Step S111, obtaining the total number of at least two stirring blades;

[0118] The total number here may be a parameter preset by the system, or a parameter obtained by real-time detection of the number of blades, or a parameter of the stirring component currently used input by the user.

[0119] Step S112, determining the angle between two adjacent stirring blades according to the total number;

[0120] Specifically, the angle values ​​of any two adjacent stirring blades are equal. Based on this, if the total number of stirring blades is different, the corresponding angle values ​​are different. Specifically, a corresponding relationship between the number of stirring blades and the angle value can be established based on the circumferential angle, so that the total value of the angle value corresponding to the number of stirring blades is the circumferential angle. The corresponding corresponding relationship can be a calculation relationship, a mapping relationship, etc. Based on the corresponding relationship, the angle value corresponding to the current total number of stirring blades can be determined.

[0121] Specifically, in this embodiment, the total number is defined as N, the circumferential angle is 360 degrees, and the angle value = 360 / N.

[0122] Step S113, determining an angle value greater than or equal to the included angle value as a target swing angle.

[0123] In the set of angles greater than or equal to the above angle value, one of them can be randomly selected or selected according to a preset rule as the target swing angle. Specifically, among all angle values ​​greater than or equal to the angle value, an angle less than a set angle threshold can be arbitrarily selected as the target swing angle, or a setting parameter input by a user can be obtained, and an angle less than the set angle threshold can be selected as the target swing angle based on the setting parameter of the user, or an angle less than the set angle threshold can be selected as the target swing angle based on the cooking characteristic parameters of the current cooking device (such as the cooking operation type and / or the cooking food type). For example, when the cooking food type is solid, its target swing angle can be greater than the target swing angle when the cooking food type is liquid.

[0124] Here, the target swing angle of the stirring blade is obtained through steps S111 to S113, so as to ensure that when the stirring component rotates within the target angle, at least two stirring blades can cooperate to achieve 360-degree stirring of the food in the pot, while limiting the torsion angle of the stirring component to reduce the wear of the seal and ensuring the uniformity of the stirring of the food.

[0125] Further, based on any of the above embodiments, another embodiment of the control method of the cooking device of the present application is proposed. In this embodiment, step S20 includes:

[0126] Step S20a, controlling the stirring assembly to reciprocate within a target angle.

[0127] Specifically, the stirring component can rotate in a first direction, and when its stirring angle reaches a target angle, it switches to rotate in a second direction. The first direction is opposite to the second direction.

[0128] Based on this, while limiting the torsion angle of the stirring component to reduce the wear of the seal, the reciprocating rotation of the stirring component can ensure the uniformity of the food in the pot.

[0129] Specifically, in this embodiment, refer to Figure 7 , step S20a comprises:

[0130] Step S21, controlling the stirring component to rotate in a first direction;

[0131] Step S22, when the duration of the stirring component rotating in the first direction is greater than or equal to the target rotation duration corresponding to the target angle, control the stirring component to switch to rotating in the second direction; wherein the first direction is opposite to the second direction.

[0132] Specifically, the starting time when the stirring component starts to rotate in the first direction can be used as the timing starting point of the duration. The stirring component can start to rotate in the first direction when it reaches a specified position (such as the first preset position or the second preset position), or when it receives a set instruction (such as a stirring start instruction).

[0133] Specifically, the stirring motor can be controlled to rotate forward so that the stirring component rotates in a first direction; and the stirring motor can be controlled to rotate reversely so that the stirring component rotates in a second direction.

[0134] The target rotation duration is specifically set according to the target angle. When the rotation speed of the stirring component is constant, the target rotation duration increases with the increase of the target angle. Specifically, due to different cooking requirements of the cooking equipment, the required rotation speed of the stirring component may be different. When the stirring component rotates in the first direction or the second direction, it can be determined according to the current cooking characteristic parameters of the cooking equipment (such as cooking operation type and / or cooking food type, etc.). Based on this, in order to make the determined target rotation duration more accurate, the rotation speed of the stirring component can be obtained; the target rotation duration is determined according to the rotation speed and the target angle. The rotation speed here specifically refers to the angular velocity of the stirring component rotation, which can be obtained by obtaining the rotation speed of the motor output shaft. The target rotation duration can be calculated based on the obtained rotation speed and target angle. For example, target rotation duration = target angle / rotation speed.

[0135] After the stirring component switches to rotate in the second direction, the stirring component may stop when the set time has passed, or the duration of the stirring component rotating in the second direction may be obtained, and when the duration is greater than or equal to the target rotation time, the process returns to step S21. The set time may be less than or equal to the target rotation time.

[0136] In this embodiment, the target rotation time corresponding to the target angle is used to limit the continuous rotation time of the stirring component when it rotates in a certain direction, thereby effectively avoiding excessive torsion angle of the seal in a single direction, thereby reducing the wear of the seal and ensuring the sealing of the pot body during stirring.

[0137] Further, based on the above embodiment, another embodiment of the control method of the cooking device of the present application is proposed. In this embodiment, step S20a may include: obtaining the current position of the identification part, determining the positional relationship between the current position and the target operating position, the target operating position is determined according to the target angle; determining the rotation parameters of the stirring component according to the positional relationship; controlling the operation of the stirring component according to the determined rotation parameters, so that the stirring component reciprocates within the target angle.

[0138] Wherein, the identification part is arranged on the stirring component or on the output shaft of the stirring motor, and the identification part has different positions when the stirring component rotates.

[0139] Specifically, the target rotation range of the marking portion corresponding to the target angle can be determined, and one or more positions within the target rotation range can be selected as the target operating position. For example, the critical position, midpoint position, etc. of the target rotation position can be selected as the target operating position.

[0140] The rotation parameters here specifically include the rotation speed and / or direction of the stirring component, etc. Specifically, the determined operating parameters may be parameters that cause the stirring component to reciprocate within a target angle.

[0141] Specifically, in this embodiment, the target operating position includes a first preset position and a second preset position, a line connecting the first preset position and the rotating shaft of the stirring component is defined as a first reference line, a line connecting the second preset position and the rotating shaft is defined as a second reference line, and the angle between the first reference line and the second reference line is a target angle. Based on this, a first position relationship of the current position relative to the first preset position and the second preset position can be obtained; the target direction of the stirring component is determined according to the first position relationship. The first position relationship specifically includes that the current position is located at the first preset position, the current position is not located at the first preset position, the current position is located at the second preset position, the current position is not located at the second preset position, the position deviation between the current position and the first preset position, and / or the position deviation between the current position and the first preset position. Different first position relationships correspond to different target directions of the stirring component. The direction of the stirring component specifically includes a first direction and a second direction. Specifically, one of the first direction and the second direction can be determined as the target direction based on the first position relationship. In this embodiment, if the first position relationship is that the current position is located at the second preset position, the first direction is determined as the operating parameter; if the first position relationship is that the current position is located at the first preset position, the second direction is determined as the operating parameter; wherein the rotation direction of the stirring component corresponding to the first direction is toward the first preset position, and the rotation direction of the stirring component corresponding to the second direction is toward the second preset position. Specifically, when the stirring motor rotates in the second direction or receives a stirring start instruction, if it is detected that the current position of the identification part is located at the second preset position, the stirring motor can be switched to operate in the first direction; when the stirring motor rotates in the first direction or receives a stirring start instruction, if it is detected that the current position of the identification part is located at the first preset position, the stirring motor can operate in the second direction.

[0142] Specifically, in this embodiment, refer to Figure 8 , step S20a comprises:

[0143] Step S23, when the stirring component rotates in the first direction, if the marking portion reaches the first preset position, the stirring component is controlled to switch to rotate in the second direction;

[0144] Step S24, when the stirring component rotates in the second direction, if the marking portion reaches the second preset position, the stirring component is controlled to switch to rotate in the first direction;

[0145] When the stirring component starts stirring, the stirring component can be controlled to rotate in a fixed direction or any direction of the first direction and the second direction. For example, the rotation direction of the stirring component can be determined based on user-set parameters.

[0146] During the process of the stirring component rotating in the first direction or the second direction, the position information of the identification part can be obtained by reading the detection parameters of the detection module corresponding to the identification part. The position information is the position characteristic parameter of the identification part relative to the first preset position and the second preset position. The position information may specifically include the identification part being located at the first preset position, the identification part being located at the second preset position, the identification part being located between the first preset position and the second preset position, etc. In addition, the position information may also include the position deviation between the identification part and the first preset position and / or the position deviation between the identification part and the second preset position, etc. During the process of the stirring component rotating in the second direction, when the detected position information is that the identification part is located at the second preset position, the stirring component can be controlled to switch to the first direction of rotation, and when the detected position information is that the identification part is located between the first preset position and the second preset position, the stirring component is controlled to maintain the second direction of rotation; during the process of the stirring component rotating in the first direction, when the detected position information is that the identification part is located at the first preset position, the stirring component can be controlled to switch to the second direction of rotation, and when the detected position information is that the identification part is located between the first preset position and the second preset position, the stirring component is controlled to maintain the first direction of rotation.

[0147] The above step S23 or step S24 may be performed during the rotation process. It should be noted that the execution order of step S23 and step S24 is not specifically limited, and is specifically determined according to the current rotation direction of the stirring component.

[0148] In this embodiment, the first preset position and the second preset position that form the target angle are used to limit the position of the identification part of the stirring component during the rotation process, thereby achieving the limitation of the torsion angle of the stirring component, thereby effectively avoiding excessive torsion angle of the seal in any direction, thereby reducing the wear of the seal and ensuring the sealing of the pot body during stirring.

[0149] Specifically, in this embodiment, combined with Figure 3, the cooking device includes a shell and at least two detection modules, the pot body and the stirring motor are both installed in the shell, at least two detection modules are spaced and fixed in the shell, and the identification part is a signal module matching the detection module; based on this, in the process of the stirring component rotating in the first direction or in the second direction, the first detection parameter of each detection module is obtained; the target signal recognition operation is performed on each first detection parameter to obtain a first recognition result; the target signal is a signal generated by the signal module; the target position reached by the identification part is determined according to the first recognition result. Here, in the process of the stirring component rotating, the identification part rotates to different positions, the corresponding rotation angles of the stirring component are different, and the distance relative to each detection module is different, then the strength or existence of the target signal in the first recognition result corresponding to the first detection parameter of each detection module is different. Based on this, different first recognition results can correspond to different positions of the identification part, and the target position reached by the identification part during the rotation of the stirring component can be determined according to the current first recognition result.

[0150] In this embodiment, at least two detection modules matching the signal module are provided, and the signal generated by the identification part during the rotation of the stirring component is detected by at least two detection modules, so as to achieve accurate measurement of the current rotation position of the stirring component during the rotation, thereby achieving accurate control of the stirring angle of the stirring component, so as to reduce the wear of the seal while ensuring the stirring effect of the stirring component on the food in the pot.

[0151] Furthermore, in this embodiment, combined with Figure 3 , each detection module corresponds to a preset position of the identification part, the preset positions corresponding to at least two detection modules include a first preset position and a second preset position, and the at least two detection modules include a first detection module and a second detection module, the first detection module is set corresponding to the first preset position, and the second detection module is set corresponding to the second preset position. Specifically, the detection range of each detection module may be limited to covering the corresponding preset position, but not covering other positions other than the corresponding preset position. Based on this, the step of determining the target position reached by the identification part according to the first recognition result includes:

[0152] When the first recognition result is that the first detection parameter of the first detection module includes the target signal, determining the target position to be the first preset position;

[0153] When the first recognition result is that the first detection parameter of the second detection module includes the target signal, the target position is determined to be the second preset position.

[0154] In addition, when the first recognition result is that the first detection parameter of the first detection module does not include the target signal, the position outside the first preset position is the target position. When the first recognition result is that the first detection parameter of the second detection module does not include the target signal, the position outside the second preset position is determined to be the target position.

[0155] In this embodiment, whether the identification portion is located at the first preset position or the second preset position is accurately measured by the detection parameters of the corresponding detection modules, thereby further improving the accuracy of the stirring angle control of the stirring component, further reducing the wear of the seal, and ensuring the stirring effect of the stirring component on the food in the pot.

[0156] In addition, in other embodiments, when the first recognition result is that the first detection parameters corresponding to the first detection module and the second detection module respectively contain the target signal, the first signal strength of the target signal in the first detection parameter corresponding to the first detection module can be determined, and the second signal strength of the target signal in the first detection parameter corresponding to the second detection module can be determined, and the first detection parameter corresponding to the strongest signal of the first signal strength and the second signal strength is determined as the target parameter, and the preset position corresponding to the target parameter is determined as the target position. Specifically, if the first signal strength is greater than the second signal strength, the first preset position is used as the target position; if the second signal strength is greater than the first signal strength, the second preset position is used as the target position.

[0157] Further, when at least two detection modules include a first detection module and a second detection module, and the preset positions corresponding to at least two detection modules include a first preset position and a second preset position, when the identification portion reaches the first preset position, the stirring component can be controlled to rotate in the first direction, and when the identification portion reaches the second preset position, the stirring component can be controlled to rotate in the second direction. Based on this, when the identification portion reaches the first preset position or the second preset position, the timing can be started and the position of the identification portion can be detected. When the timing duration or the position of the detected identification portion reaches any of the conditions in the above steps S22, S23 and S24, the stirring component can be switched to run. For example, when the identification portion reaches the first preset position, the stirring component is controlled to rotate in the first direction and the timing is started to obtain the first duration. When the first duration is less than the target rotation duration, if the identification portion reaches the second preset position, the stirring component can be controlled to switch to rotate in the second direction. When the stirring component switches to rotate in the second direction, the timing is started to obtain the second duration. When the second duration is less than the target rotation duration, if the identification portion reaches the first preset position, the stirring component can be controlled to switch to rotate in the first direction. For another example, timing starts when the stirring component starts to rotate in the first direction to obtain a third duration. When the third duration is greater than or equal to the target rotation duration, the stirring component can be controlled to switch to rotation in the second direction when the marking portion has not reached the second preset position, or can be controlled to switch to rotation in the second direction when the marking portion reaches the second preset position. Timing starts when the stirring component starts to rotate in the second direction to obtain a fourth duration. When the fourth duration is greater than or equal to the target rotation duration, the stirring component can be controlled to switch to rotation in the first direction when the marking portion has not reached the first preset position, or can be controlled to switch to rotation in the first direction when the marking portion reaches the first preset position.

[0158] Further, based on the above two embodiments, another embodiment of the control method of the cooking device of the present application is proposed. In this embodiment, before step S20a, it also includes:

[0159] Step S01, when the cooking device is powered on, obtaining position feature information of the identification part;

[0160] The marking part is arranged on the stirring component or the output shaft of the stirring motor, and the marking part has different positions when the stirring component rotates. The marking part here is the same concept as the marking part in the above embodiment, and will not be described in detail here.

[0161] The position characteristic information is specifically characteristic information representing the current position of the identification part. The position characteristic information can be obtained by analyzing the detection parameters of the detection module corresponding to the identification part.

[0162] Step S02, determining whether the position characteristic information indicates that the identification portion is located at a third preset position;

[0163] When the position characteristic information indicates that the identification part is located at the third preset position, step S20a is executed; when the position characteristic information indicates that the identification part is located at a position other than the third preset position, step S03 is executed. After step S03, the process may return to executing the acquisition of the position characteristic information of the identification part.

[0164] Specifically, the position where the marking portion is located when the torsional force of the flexible section of the seal is less than a set threshold (such as 0) can be selected as the third preset position.

[0165] Among them, when the identification part is located at the third preset position, if the third preset position is one of the first preset position and the second preset position mentioned above, when step S20a includes step S21 and step S22, step S21 and step S22 can be directly executed; when step S20a includes step S23 and step S24, when the third preset position is the first preset position, the stirring component can be controlled to rotate in the first direction and then step S23 is executed, and when the third preset position is the second preset position, the stirring component can be controlled to rotate in the second direction and then step S24 is executed.

[0166] When the identification portion is located at the third preset position, if the third preset position is located between the above-mentioned first preset position and the second preset position, when step S20a includes step S21 and step S22, the stirring component can be controlled to rotate in any one of two opposite directions, and step S21 and step S22 are executed when the position of the identification portion reaches one of the first preset position and the second preset position; when step S20a includes step S23 and step S24, the stirring component can be controlled to rotate in any one of the two opposite directions and then step S23 and step S24 are executed.

[0167] Step S03, controlling the stirring assembly to rotate to adjust the position of the marking portion to a third preset position.

[0168] When the current position of the identification part needs to be adjusted, when the direction in which the current position points to the third preset position is the first direction, the stirring component can be controlled to rotate along the first direction and return to execute the step of obtaining the position characteristic information of the identification part; when the direction in which the current position points to the third preset position is the second direction, the stirring component can be controlled to rotate along the second direction and return to execute the step of obtaining the position characteristic information of the identification part. For example, when it is recognized that the position characteristic information is that the identification part is located on the left side of the third preset position, the stirring component can be controlled to rotate to the right, and the position characteristic information of the identification part is detected in real time while the stirring component rotates. When the position characteristic information is that the identification part is located at the third preset position, it can be considered that the position calibration of the stirring component is completed, and the stirring component can be controlled to start reciprocating within the target angle.

[0169] In this embodiment, after power-on, the initial position of the identification portion is first calibrated through the third preset position, and then the stirring component is controlled to reciprocate within the target angle, thereby further improving the accuracy of the stirring angle control of the stirring component.

[0170] Furthermore, in the present embodiment, the cooking device includes a shell and at least two detection modules, the pot body and the stirring motor are both installed in the shell, at least two detection modules are spaced and fixed in the shell, and the identification part is a signal module matching the detection module; the step of obtaining the position characteristic information of the identification part includes: obtaining the second detection parameter of each detection module; performing the target signal recognition operation on each second detection parameter to obtain the second recognition result; the target signal is the signal generated by the signal module; and determining the position characteristic information according to the second recognition result. The position characteristic information here is similar to the determination method of the arrival position of the identification part mentioned above, and will not be repeated here. In the present embodiment, by setting at least two detection modules matching the signal module, the signal generated by the identification part during the rotation of the stirring component is detected by at least two detection modules, so as to realize the accurate measurement of the initial position of the stirring component when it is powered on, and ensure the accuracy of the calibration of the initial position of the stirring component, so as to further improve the accuracy of the stirring angle control of the stirring component.

[0171] Specifically, in this embodiment, combined with Figure 3 , each detection module corresponds to a preset position of the identification part, the preset positions corresponding to at least two detection modules include a third preset position, and at least two detection modules include a third detection module corresponding to the third preset position. Specifically, the detection range of each detection module is limited to covering the corresponding preset position, and does not cover other positions outside the corresponding preset position. The step of determining the position characteristic information according to the second recognition result includes: when the second recognition result is that the second detection parameter of the third detection module contains the target signal, determining the position characteristic information as the identification part is located at the third preset position; when the second recognition result is that the second detection parameter of the third detection module does not contain the target signal, determining the position characteristic information as the identification part is located at a position other than the third preset position.

[0172] Specifically, in this embodiment, at least two detection modules include the first detection module and the second detection module in addition to the third detection module, and the preset positions corresponding to the at least two detection modules also include the first preset position and the second preset position. Specifically, the third preset position is located between the first preset position and the second preset position. The line between the third preset position and the rotating shaft of the stirring component is defined as the third reference line, and the third reference line is located on the angular bisector of the target angle formed by the clamping of the first reference line and the second reference line.

[0173] In this embodiment, whether the identification portion is located at the third preset position is accurately measured through the detection parameters of the corresponding third detection module including whether there is a target signal, thereby further improving the accuracy of the stirring angle control of the stirring component, further reducing the wear of the seal while ensuring the stirring effect of the stirring component on the food in the pot.

[0174] In addition, in other embodiments, when there are multiple detection modules whose detection parameters include target signals, the signal strength of the target signal in the detection parameters corresponding to each detection module can be determined, and the multiple signal strengths can be compared two by two. Based on the comparison result, it is determined whether the signal strength corresponding to the third detection module is the maximum value of all signal strengths. If so, it can be determined that the identification part is located at the third preset position as the position characteristic information of the current identification part; if not, it can be determined that the identification part is located at a position other than the third preset position as the position characteristic information of the current identification part.

[0175] Further, based on any of the above embodiments, during the execution of S20, the duration of the stirring of the cooking component is obtained, and it is determined whether the duration is less than the target stirring duration; step S20 is maintained; when the duration is greater than or equal to the target stirring duration, the stirring component is controlled to rotate to move the position of the identification portion to a third preset position. The target stirring duration can be set by the user, or can be determined based on the cooking characteristic parameters of the cooking device (such as the type of cooking food and / or the type of cooking operation, etc.). Based on this, when the duration reaches the target stirring duration, it indicates that the stirring is completed. At this time, the direction, speed, rotation duration, etc. of the stirring component are adjusted with the third preset position as the target, and the position of the corresponding identification portion is adjusted to the third preset position. In this embodiment, after the cooking device completes the stirring, the stirring motor is controlled to run by the second parameter, and the stirring component can be reset, so that the calibration of the identification portion position can be quickly completed before subsequent stirring, so that the cooking device can quickly enter the stirring state to ensure that it meets the user's cooking stirring needs.

[0176] Below, the control scheme of the cooking device involved in the embodiment of the present invention is explained with at least two preset positions including a first preset position, a second preset position and a third preset position, and at least two detection modules including a first detection module, a second detection module and a third detection module. When the cooking device is powered on, the detection parameters of the third detection module can be obtained. When the detection parameters of the third detection module include a target signal, it can be considered that the calibration of the stirring component is completed. At this time, the stirring component can be controlled to rotate in the first direction or the second direction. Wherein, when the stirring component rotates in the second direction, when the detection parameters of the second detection module include the target signal, it can be considered that the identification part of the stirring component has reached the second preset position. At this time, the stirring component can be controlled to switch to rotate in the first direction and start timing. When the timing duration is greater than or equal to the target rotation duration or when the detection parameters of the first detection module include the target signal, it can be considered that the identification part of the stirring component has reached the first preset position and the rotation angle of the stirring component has reached the target angle. At this time, the stirring component can be controlled to switch to rotate in the second direction and restart the timing. Based on the re-timing duration, the above-mentioned position obtained based on the duration and the detection parameters of the detection module is repeated to control the reciprocating rotation of the stirring component until the operation of the stirring component reaches the target stirring duration or until the user's stirring end instruction is received and the stirring component stops rotating. Wherein, before the stirring component stops rotating, when the operation of the stirring component reaches the target stirring duration or until the user's stirring end instruction is received, the stirring component can be controlled to rotate in the first direction or the second direction until the detection parameters of the third detection module include the target signal to stop the rotation of the stirring component.

[0177] The control scheme of the cooking device involved in the embodiment of the present invention is described below in a specific implementation manner:

[0178] By setting an induction magnet on the motor, the induction magnet rotates with the motor; setting A, O, and B sensors on the rotating plane, sensors A, O, and B respectively detect the rotation position of the motor, and the positions of A and B are symmetrical with respect to O, forming an angle of θ, and the motor rotates back and forth between positions AOB; the number of stirring blades is N, the stirring angle is θ1, θ1≥360 / N, the speed of the motor is n / min, and the time t=θ1*60 / n*360 between AOB and θ1 angle; θ≥θ1; when the motor rotates from position O to position A, the motor is triggered to rotate in the opposite direction, and the motor starts timing t, and reverses when time t is reached; or when the motor rotates to position B, the B sensor detects the induction magnet, the motor reverses, and the motor restarts timing t, and the cycle is repeated. Based on this, the specific process is as follows:

[0179] Step 1: Power on;

[0180] Step 2, sensor O determines whether the motor is at the initial position O;

[0181] 1) Yes, go to step 3;

[0182] 2) No, adjust the motor to the initial position O;

[0183] Step 3: The motor rotates forward to position A, then reverses, and starts timing t;

[0184] Step 4: Determine whether the time t is reached or the position B is reached, and trigger the signal?

[0185] 1) Yes, go to step 5;

[0186] 2) No, go to step 3;

[0187] Step 5: The motor reverses and resets the timing t, and then loops to step 3.

[0188] The motor here refers to the stirring motor connected to the stirring assembly. Sensors A, O, and B refer to the first detection module, the second detection module, and the third detection module, respectively. The induction magnet refers to the identification part, and the angle θ formed by the AB position here refers to the target angle.

[0189] In addition, an embodiment of the present invention further proposes a computer-readable storage medium, on which a control program of a cooking device is stored. When the control program of the cooking device is executed by a processor, the relevant steps of any embodiment of the control method of the cooking device as described above are implemented.
