[0065] 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.

[0066] The main solution of the embodiment of the present invention is: the cooking device includes a stirring component, a stirring motor, a sealing member 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 sealing member, and the control method of the cooking device includes the following steps: obtaining the current position of an identification part corresponding to the stirring component; determining the operating parameters of the stirring motor according to the positional relationship between the current position and the target operating position; the target operating position is determined according to the target rotation range corresponding to the identification part; and controlling the operation of the stirring motor according to the operating parameters so that the stirring component rotates within the target rotation range.

[0067] 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.

[0068] The present invention provides the above-mentioned solution, aiming to improve the sealing performance of the pot body during the stirring process.

[0069] 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.

[0070] In the embodiment of the present invention, refer to Figure 1 and Figure 2 The cooking device includes a pot body 11, 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.

[0071] 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 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 in the forward direction, the stirring shaft 21 can rotate in a first direction, and when the stirring motor 3 is running in the reverse direction, 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] Further, see Figure 2, in this embodiment, the seal 4 includes a first seal section 41, a second seal section 42, and a flexible section 43 connecting the first seal section 41 and the second seal section 42. The first seal section 41 is fixedly connected to the stirring assembly 2, and the second seal section 42 is fixedly connected to the pot body 1. Specifically, the first seal section 41 is connected to the stirring shaft 21 in the stirring assembly 2. The flexible section 43 is specifically made of a flexible material (such as resin, fiber, etc.). When the stirring shaft 21 rotates, the first seal section 41 will rotate with the stirring shaft 21. Since the first seal section 41 is fixed on the stirring shaft 21 and the second seal section 42 is fixed on the pot body 1, both ends of the seal 4 can be tightly connected to the stirring shaft 21 and the pot body 1 to ensure the sealing performance of the installation of the stirring assembly 2 in the pot body 1. In addition, the flexible section 43 will undergo flexible torsion as it rotates with the stirring shaft 21, while the first seal section 41 and the second seal section 42 are fixed relative to the stirring shaft 21. Due to the good flexibility of the flexible section 43, it has good anti-fatigue ability during the torsion process, thus effectively avoiding the wear of the seal 4 during the stirring process and ensuring the sealing performance of the pot body 1, preventing the food ingredients 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 forward and reverse rotations, the flexible section 43 can switch between the tightened and relaxed states, further avoiding the wear of the seal 4 during the rotation process.

[0076] Further, referring to Figure 1 , the cooking device further includes a housing 5, and the pot body 1 and the stirring motor 3 are both installed inside the housing 5. Specifically, the stirring motor 3 can be fixed to the bottom of the housing 5 through a motor bracket 6, and the pot body 1 is detachably connected to the housing 5. Specifically, when the pot body 1 is separated from the housing 5, the stirring assembly 2 in the pot body 1 is separated from the stirring motor 3; when the pot body 1 is placed inside the housing 5, the stirring assembly 2 in the pot body 1 is connected to the stirring motor 3. Here, the motor bracket 6 can specifically be 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 or placed into the housing 5 according to the actual needs of the user. And when the pot body 1 is inside the housing 5, the control device will perform cooking operations or stirring operations.

[0077] Specifically, referring to Figure 3 , a marking portion 9 may be provided on the stirring assembly 2 (such as on the stirring shaft 21) or the output shaft of the stirring motor 3 for marking the rotation position of the stirring assembly 2. When the stirring assembly 2 rotates, the marking portion 9 has different positions. Define the central axis of the rotation of the stirring assembly 2 as its rotation axis a. Specifically, when the marking portion 9 is provided on the stirring assembly 2, the stirring assembly 2 includes a stirring shaft 21 and stirring blades 22, and 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.

[0078] The specific type of the identification unit 9 can be set according to actual requirements. A detection module 7 that cooperates with the identification unit 9 can be provided inside the cooking device. The detection module 7 can be used to detect the position of the identification unit 9 to detect the rotation position of the stirring assembly 2. Specifically, the detection module 7 can be connected to the control device so that the control device can obtain the current position of the stirring assembly 2 based on the detection signal of the detection module 7. The number of the detection modules 7 can be set according to actual requirements (such as its detection range, the size of the target angle, etc.), and can be one, two, three, four or more.

[0079] In this embodiment, the identification unit 9 is a signal module that matches the detection module 7. The detection module 7 can detect the signal generated by the signal module to locate the current rotation position of the stirring assembly 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 this 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, and the magnetic sensor can determine the position of the identification unit 9 by detecting the magnetic signal, so as to obtain the rotation position of the stirring assembly 2.

[0080] Further, in this embodiment, referring to Figure 3 , the cooking device includes at least two detection modules 7. The at least two modules are spaced apart and fixed inside the housing 5, and each detection module 7 corresponds to a preset position of the identification unit 9 respectively. Specifically, the detection area of each detection module 7 at least covers the corresponding preset position.

[0081] The preset position is specifically a default position selected in advance from the set of positions that the identification unit 9 can reach. The number of preset positions is at least two. The specific number can be the same as the number of the detection modules 7, or can be less than the number of the detection modules 7. That is to say, there may be a situation where one preset position corresponds to more than one detection module 7. For example, when the at least two detection modules 7 include a first module and a second module, the at least two preset positions can include a first position corresponding to the first module and a second position corresponding to the second module; another example is that when the at least two detection modules 7 include a first module, a second module, a third module, and a fourth module, the at least two preset positions can 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.

[0082] Define the connection line between the preset position and the rotating shaft a of the stirring assembly 2 as the reference line. Then, the maximum included angle formed by at least two reference lines is less than or equal to 360 degrees. Specifically, in this embodiment, the maximum included angle formed by at least two reference lines is less than or equal to 180 degrees. The specific value of the maximum included angle here can be set according to actual requirements. In this embodiment, the maximum included 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 according to the included angle between the stirring blades 22.

[0083] In this embodiment, the detection area of each detection module 7 is limited to covering its corresponding preset position and does not cover 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 assembly 2 is located at the preset position corresponding to this 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 assembly 2 is located at other positions outside the preset position corresponding to this detection module 7.

[0084] The number of at least two detection modules 7 can be set to two, three or more according to actual requirements. Specifically, at least two detection modules 7 are arranged around the rotating shaft a corresponding to the stirring assembly 2.

[0085] Specifically, in this embodiment, referring to Figure 3 , at least two preset positions include the first preset position X and the second preset position Z. Then, at least two detection modules 7 include the first detection module 71 and the 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 connection line between the rotating shaft a of the stirring assembly 2 and the first detection module 71 as the first reference line, define the connection line between the rotating shaft a and the second detection module 72 as the second reference line, define the connection line between the first preset position X and the rotating shaft a of the stirring assembly 2 as the fourth reference line, and define the connection line between the second preset position Z and the rotating shaft a of the stirring assembly 2 as the fifth 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 included angle between the first reference line and the second reference line is the target angle of rotation of the stirring assembly 2, and the target angle is less than the set angle threshold. Thus, based on the signal detection of the identification portion 9 by the first detection module 71 and the second detection module 72, the rotation of the stirring assembly 2 is restricted within a smaller target angle.

[0086] Further, referring to Figure 3, in addition to the first preset position X and the second preset position Z, there are at least two preset positions, and also include a third preset position Y. In addition to the first detection module 71 and the second detection module 72, there are at least two detection modules 7, and also include a third detection module 73. Based on this, the connection line between the third detection module 73 and the rotating shaft a is defined as the third reference line, and the third reference line is located between the first reference line and the second reference line. Among them, when the signal module is located at the third preset position Y, the flexible section 43 of the above-mentioned seal 4 is in a completely relaxed state, that is, the torsional force is less than the set threshold (such as 0). The farther the position of the signal module is from the third preset position Y, the greater the torsional force on the seal 4. Specifically, the connection line between the third preset position Y and the rotating shaft a of the stirring assembly 2 is defined as the sixth reference line, and the third reference line and the sixth reference line are collinear. In this embodiment, the third reference line is the angular bisector of the angle between the first reference line and the second reference line. In other embodiments, the third reference line can also be set at other positions between the first reference line and the second reference line according to actual needs.

[0087] The third preset position Y can be used to calibrate the initial position of the stirring assembly 2. At the start of stirring, the third detection module 73 can detect the signal generated by the signal module to detect the current rotation position of the stirring assembly 2. Starting further stirring operations only when it is determined based on the signal detected by the third detection module 73 that the signal module of the stirring assembly 2 is currently located at the third preset position Y can ensure the accuracy of the position control during the rotation of the stirring assembly 2.

[0088] Furthermore, in this embodiment, referring to Figure 1 , the cooking device further includes a heating assembly 8, and the heating assembly 8 is used to heat the pot body 1.

[0089] In this 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 when the coil assembly is powered on to heat the pot body 1; and stops heating the pot body 1 when the coil assembly is powered off. Specifically, in this embodiment, the heating assembly 8 further includes a mounting seat, the mounting seat is located at the bottom of the pot body 1, the mounting seat is formed with a mounting groove, the coil assembly is arranged in the mounting groove and is spaced 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 is located on the four sides of the mounting platform. A second through hole is formed in the mounting platform, and the output shaft of the stirring motor 3 can pass through the second through hole and is connected to one end of the stirring assembly 2 passing through the first through hole.

[0090] In the embodiment of the present invention, referring 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 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 through a communication bus. The memory 1002 can be a high-speed RAM memory or a stable memory (non-volatile memory), such as a disk memory. Optionally, the memory 1002 can also be a storage device independent of the aforementioned processor 1001.

[0091] Those skilled in the art can understand that Figure 4 the device structure shown in

[0092] does not constitute a limitation on the device, and may include more or fewer components than shown in the figure, or combine some components, or have different component arrangements. Figure 4 As shown, the memory 1002, as a computer-readable storage medium, may include a control program for the cooking device. In Figure 4 the device shown, the processor 1001 can be used to call the control program for 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 embodiments.

[0093] The embodiment of the present invention also provides a control method for a cooking device to control the operation of the above-mentioned cooking device.

[0094] Referring to Figure 5 , an embodiment of the control method for 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 seal, the control method of the cooking device includes:

[0095] Step S10, obtaining the current position of the identification part corresponding to the stirring component;

[0096] The identification part here is fixed relative to the stirring component. The identification part is provided on the stirring component or the output shaft of the stirring motor, and has different positions when the stirring component rotates.

[0097] The current position of the identification part can be specifically obtained by analyzing the parameters detected by the detection module corresponding to the identification part provided in the cooking device.

[0098] Step S20, determining the operating parameters of the stirring motor according to the positional relationship between the current position and the target operating position; the target operating position is determined according to the target rotation range corresponding to the identification part;

[0099] The specific target rotation range is the range allowed for the position of the identification part during the rotation of the stirring assembly. The target rotation range can be a parameter set by the system by default, or a parameter set by the user, or can be determined based on the stirring characteristic parameters of the stirring assembly (such as the number of stirring blades, the required stirring angle, etc.).

[0100] Corresponding to the target rotation range, there is a target angle for the rotation of the stirring assembly, and the target angle decreases as the target rotation range decreases. Among them, the rotation angle of the stirring assembly corresponding to the target rotation range is less than the set angle threshold. The fact that the target angle is less than the set angle threshold indicates that the rotation angle of the stirring assembly is a smaller angle not exceeding the set angle threshold. The set angle threshold can be set by the user, or a parameter determined based on the stirring characteristic parameters of the stirring assembly, or a parameter determined based on the current cooking characteristic parameters of the cooking device. In this embodiment, the set angle threshold is 360 degrees. Based on this, the target angle of rotation of the stirring assembly is less than 360 degrees. In another embodiment, the set angle threshold can also be 180 degrees. Based on this, the target angle of rotation of the stirring assembly 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.

[0101] Specifically, one or more positions within the target rotation range can be selected as the target operating positions. For example, the critical positions, midpoint positions, etc. of the target rotation positions can be used as the target operating positions.

[0102] The positional relationship between the current position and the target operating position includes that the current position is located at the target operating position, the current position is not located at the target operating position, the positional deviation between the current position and the target operating position, the direction of the current position relative to the target operating position, etc.

[0103] The motor operating parameters here are specifically the parameters related to driving the rotation of the stirring assembly. The operating parameters specifically include the rotational speed and / or rotation direction of the motor, etc.

[0104] Different positional relationships correspond to different motor operating parameters. The correspondence between the positional relationship and the operating parameters can be set in advance, and based on the preset correspondence, the operating parameters of the stirring motor corresponding to the current positional relationship can be determined.

[0105] Specifically, the determined operating parameters can be parameters for the stirring assembly to reciprocate within the target angle corresponding to the target rotation range, or can be parameters for the stirring assembly to rotate unidirectionally within the target rotation range.

[0106] Step S30, control the stirring motor to operate according to the operating parameters so that the stirring assembly rotates within the target rotation range.

[0107] The specific rotation of the stirring component within the target rotation range means that during the rotation of the stirring component, the position of the corresponding identification part of the stirring component is restricted within the target rotation range, so as to limit the rotation angle of the stirring component within the target angle corresponding to the target rotation range.

[0108] A control method for a cooking device according to an embodiment of the present invention. This method determines the operating parameters of the stirring motor based on the position relationship between the current position of the identification part corresponding to the stirring component and the target operating position. Since the target operating position is determined according to the target rotation range corresponding to the identification part, the stirring motor operates according to the determined operating control parameters, and the stirring component can be restricted to rotate within the target rotation range. Based on this, the restriction of the position is used to realize the restriction of the torsion angle of the stirring component, which is beneficial to reducing the wear of the seal between the stirring component and the pot body and effectively improving the sealing performance of the pot body during the stirring process.

[0109] 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, the target operating position includes a first target position and a second target position, and the first target position and the second target position are critical positions of the target rotation range. Referring to Figure 6 , step S20 includes:

[0110] Step S21, obtaining the first position relationship between the current position and the first target position and the second target position;

[0111] The first position relationship specifically includes that the current position is located at the first target position, the current position is not located at the first target position, the current position is located at the second target position, the current position is not located at the second target position, the position deviation between the current position and the first target position, and / or the position deviation between the current position and the first target position, etc.

[0112] The first position relationship can be obtained by comparing the current position with the first target position and the second target position respectively or calculating the position deviation.

[0113] Step S22, determining the target rotation direction of the stirring motor according to the first position relationship;

[0114] Different first position relationships correspond to different target rotation directions of the stirring motor. The rotation directions of the stirring motor specifically include a first rotation direction and a second rotation direction. Specifically, one of the first rotation direction and the second rotation direction can be determined as the target rotation direction based on the first position relationship.

[0115] Specifically, in this embodiment, if the first positional relationship is that the current position is at the first target position, the first rotation direction is determined as the operating parameter; if the first positional relationship is that the current position is at the second target position, the second rotation direction is determined as the operating parameter; wherein, the rotation direction of the stirring component corresponding to the first rotation direction is towards the second target position, and the rotation direction of the stirring component corresponding to the second rotation direction is towards the first target position. Specifically, during the process of the stirring motor rotating in the second rotation direction or when receiving the stirring start instruction, if it is detected that the current position of the identification portion is at the first target position, the stirring motor can operate in the first rotation direction; during the process of the stirring motor rotating in the first rotation direction or when receiving the stirring start instruction, if it is detected that the current position of the identification portion is at the second target position, the stirring motor can operate in the second rotation direction.

[0116] Specifically, during the process of the stirring motor rotating in the first rotation direction or the second rotation direction, the position characteristic information of the identification portion can be analyzed by reading the detection parameters of the detection module correspondingly set for the identification portion. The position information is the characteristic parameter of the identification portion relative to the first target position and the second target position. During the process of the stirring motor rotating in the second rotation direction, when the detected position characteristic information is that the identification portion is at the first target position, the stirring motor can be controlled to switch to rotating in the first rotation direction, and when the detected position information is that the identification portion is between the first target position and the second target position, the stirring motor is controlled to maintain rotating in the second rotation direction; during the process of the stirring component rotating in the first rotation direction, when the detected position information is that the identification portion is at the second target position, the stirring motor can be controlled to switch to rotating in the second rotation direction, and when the detected position information is that the identification portion is between the first target position and the second target position, the stirring motor is controlled to maintain rotating in the first rotation direction.

[0117] Step S23, determine the target rotation direction as the operating parameter.

[0118] In this embodiment, the rotation direction of the stirring motor is determined by the first positional relationship between the current position and the two critical positions of the target rotation range of the identification portion, so that the rotation direction of the stirring component can be adjusted to adapt to the boundary position of its identification portion relative to the target rotation range, thereby realizing the effective improvement of the pot body sealing performance during the stirring process by regulating the motor rotation direction. Among them, when the identification portion is at the first target position, the stirring motor operates in the first rotation direction, and when the identification portion is at the second target position, the stirring motor operates in the second rotation direction, that is, when the identification portion reaches the critical position of the target rotation range, the stirring components rotate towards each other respectively, so that the stirring component can reciprocally rotate within the target angle corresponding to the target rotation range, and the rotation angle of the stirring component can be accurately limited within the target angle.

[0119] Further, based on the above embodiments, another embodiment of the control method of the cooking device of the present application is proposed. In this embodiment, the target operating position further includes a third target position, and the third target position is located between the first target position and the second target position. Specifically, the third target position here can be a position pre-configured in the system or a position selected by the user. In this embodiment, specifically, the position where the identification part is located when the torsional force of the flexible section of the seal is less than a set threshold (such as 0) can be pre-selected as the third target position. Based on this, referring to Figure 7 , before step S21, it further includes:

[0120] Step S201, obtain the operating state of the cooking device;

[0121] After step S201, when the operating state is the power-on state, execute step S202; when the operating state is the stirring state, execute step S21.

[0122] The cooking device starts timing when it switches from power-off to power-on. When the timing duration is less than or equal to the set duration, it can be determined that the operating state of the cooking device is the power-on state. During the operation of the cooking device after power-on (that is, when the timing duration is greater than the set duration), when the stirring motor is in the running state, it drives the stirring assembly to rotate. At this time, the operating state of the cooking device is the stirring state; if the stirring motor is in the stopped running state, then the operating state of the cooking device at this time is the non-stirring state. Specifically, during the operation of the cooking device after power-on, if a stirring start instruction of the cooking device is received, the stirring motor can be controlled to rotate in either the first direction or the second direction to make the cooking device enter the stirring state. Further, during the operation of the cooking device after power-on, the cooking function information selected by the user can be obtained, and based on the cooking function information, it can be determined whether the corresponding cooking operation requires the stirring function. If there is a stirring function requirement, the heating component can be controlled to start heating and the stirring motor can be controlled to start running.

[0123] Step S202, determine the operating parameters according to the second position relationship between the current position and the third target position;

[0124] The second position relationship here includes that the current position is located at the third target position, the current position is not located at the third target position, and the position deviation between the current position and the third target position, etc.

[0125] The second position relationship can be obtained by comparing the current position with the third target position respectively or calculating the position deviation.

[0126] The operating parameters include the rotation direction, rotation speed, and / or rotation duration of the stirring motor, etc. Different second position relationships correspond to different operating parameters of the stirring motor. Specifically, the target rotation direction of the motor can be selected between the first rotation direction and the second rotation direction of the stirring motor based on whether the current position is located at the third target position; the rotation speed and / or rotation duration of the motor can also be determined based on the position deviation between the current position and the third target position.

[0127] Specifically, the operating parameters determined based on the current position and the third target position here are the parameters for making the position of the identification part reach the third target position.

[0128] In this embodiment, step S202 includes: if the second position relationship is that the current position is located at the third target position, it is determined that starting the motor operation is the operating parameter; if the second position relationship is that the current position is located at a position other than the third target position, it is determined that the operating parameter is the first parameter, and the first parameter is the parameter for adjusting the position of the identification part to the third target position. The current position being located at the third target position indicates that the initial position when the identification part is powered on has been calibrated. At this time, starting the motor operation can ensure the accuracy of the angle regulation of the stirring assembly during the stirring state. Specifically, after the second position relationship is that the current position is located at the third target position, the step of determining that starting the motor operation is the operating parameter can be executed only when a stirring start instruction or a cooking function demand for stirring is detected by the user, so as to ensure that the stirring process can meet the user's cooking needs. In addition, if the current position of the identification part is located at the third target position, the operation of the stirring motor (such as rotation speed, rotation direction, rotation duration, etc.) is regulated with the third target position as the target, so as to adjust the position of the identification part to the third target position, thereby realizing the calibration of the initial position of the identification part. Among them, after the calibration is completed, it can be re-identified whether the current position is located at the third target position, and corresponding regulation is performed based on the identification result.

[0129] In this embodiment, when powered on, the position of the identification part is first adjusted based on the third target position, and then the position of the identification part is restricted based on the first target position and the second target position during the stirring state, so as to ensure precise regulation by restricting the rotation angle of the stirring assembly within the target angle, further reducing the wear of the seal during the stirring process, and further ensuring zero leakage of the pot body during the stirring process.

[0130] It should be noted that in other embodiments, when in the stirring state, other methods other than step S21 and step S22 can also be used to determine the operating parameters of the motor. For example, the target operating position includes one of the first target position and the second target position, and the operating parameters of the motor are determined based on the third position relationship between one of the first target position and the second target position and the current position of the identification part.

[0131] Furthermore, in this embodiment, before step S21, it also includes:

[0132] Step S01: When the operating state is the stirring state, obtain the duration of the stirring state.

[0133] Step S02: Determine whether the duration is less than the target stirring duration.

[0134] When the duration is less than the target stirring duration, execute Step S21; when the duration is greater than or equal to the target stirring duration, execute Step S03.

[0135] Step S03: Determine that the operating parameter is the second parameter, and the second parameter is the parameter for adjusting the position of the identification part to the third target position.

[0136] The target stirring duration can be set by the user or determined based on the cooking characteristic parameters of the cooking device (such as the type of cooked food and / or the type of cooking operation, etc.).

[0137] In this embodiment, after the cooking device finishes stirring, controlling the stirring motor to operate through the above second parameter can realize the reset of the stirring assembly, so as to quickly complete the calibration of the position of the identification part before subsequent stirring, so that the cooking device can quickly enter the stirring state and ensure that it meets the user's cooking and stirring requirements.

[0138] 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, the cooking device further includes a housing and at least two detection modules. The pot body and the stirring motor are both installed in the housing. The at least two detection modules are spaced apart and fixed in the housing. The identification part is a signal module matching the detection module. Refer to Figure 8 , Step S10 includes:

[0139] Step S11: Obtain the detection parameters of each detection module.

[0140] Step S12: Perform a target signal recognition operation on each detection parameter to obtain a recognition result; the target signal is the signal generated by the signal module.

[0141] Step S13: Determine the current position according to the recognition result.

[0142] Here, during the rotation of the stirring assembly, the identification part rotates to different positions, the corresponding rotation angles of the stirring assembly are different, and the distances from each detection module are different. Then, the strength or presence or absence 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 current position of the identification part during the rotation of the stirring assembly can be determined according to the current first recognition result.

[0143] Specifically, the correspondence between the recognition result and the current position of the identification part can be determined in advance, and this correspondence can be a calculation relationship, a mapping relationship, etc. Based on this correspondence, the current position corresponding to the current recognition result can be determined.

[0144] In this embodiment, by setting at least two detection modules that match the signal module, the signals generated by the identification part are detected by the at least two detection modules, so as to achieve accurate measurement of the current position of the stirring assembly, and thus achieve accurate control of the stirring angle of the stirring assembly, reduce the wear of the seal while ensuring the stirring effect of the stirring assembly on the ingredients in the pot.

[0145] Further, in this embodiment, in combination with Figure 3 , each detection module corresponds to a preset position of the identification part. Specifically, the detection range of each detection module is only limited to covering the corresponding preset position, and does not cover other positions outside the corresponding preset position. The steps for determining the current position according to the recognition result include:

[0146] Step S131, determining the detection parameter containing the target signal as the target detection parameter according to the recognition result;

[0147] Step S132, determining the preset position corresponding to the detection module that detects the target detection parameter as the current position.

[0148] Wherein, when there are more than one preset positions corresponding to the detection module that detects the target detection parameter, the preset position corresponding to the parameter with the strongest target signal in the target detection parameter can be used as the current position of the identification part.

[0149] The number of the detection modules and their corresponding preset positions here can be set according to actual needs. Specifically, the preset positions of the identification part can be determined according to the target running position. For example, at least one of the first target position, the second target position, and the third target position mentioned in the above embodiment can be used as the preset position here; in addition to using the above first target position, second target position, and third target position as the preset positions of the identification part, other preset positions can also be additionally set to achieve accurate measurement of the current position of the identification part.

[0150] In this embodiment, the position of the identification part is characterized by each detection module corresponding to a preset position. Based on this, through the recognition of the target signal in the detection parameters of each detection module, accurate measurement of the position of the identification part can be achieved, so as to achieve accurate control of the rotation of the stirring assembly and ensure the sealing effect of the seal.

[0151] Further, in this embodiment, in combination with Figure 3, at least two preset positions include a first preset position and a second preset position; a line connecting the first preset position and the rotating shaft of the stirring assembly is defined as a first reference line, and a line connecting the second preset position and the rotating shaft is defined as a second reference line. The first reference line and the second reference line sandwich and form the above-mentioned target rotation range. Wherein, the included angle between the first reference line and the second reference line is the target angle of rotation of the stirring assembly corresponding to the target rotation range; at least two detection modules include a first detection module and a second detection module. The first detection module corresponds to the first preset position, and the second detection module corresponds to the second preset position. Based on this, by obtaining the detection parameters of the first detection module and the second detection module, it can be known whether the current position of the identification part reaches the critical position of its target rotation range, so as to ensure that the stirring angle of the stirring assembly can be controlled by identifying the position of the identification part, and it can be ensured that the stirring angle of the stirring assembly will not exceed the target angle corresponding to the target rotation range, so as to ensure the sealing effect of the seal.

[0152] Based on this, when the first preset position is used as the above-mentioned first target position and the second preset position is used as the above-mentioned second target position, when the recognition result is that the detection parameter of the first detection module contains the target signal, the current position of the identification part is the first preset position; when the recognition result is that the detection parameter of the second detection module contains the target signal, the current position of the identification part is the second preset position; when the recognition result is that neither the detection parameter of the first detection module nor the detection parameter of the second detection module contains the target signal, the current position of the identification part is between the first preset position and the second preset position.

[0153] In addition, in other embodiments, when the first recognition result is that the detection parameters corresponding to the first detection module and the second detection module both contain the target signal, the first signal intensity of the target signal in the first detection parameter corresponding to the first detection module can be determined, and the second signal intensity of the target signal in the first detection parameter corresponding to the second detection module can be determined. The detection parameter corresponding to the stronger signal among the first signal intensity and the second signal intensity is determined as the target parameter, and the preset position corresponding to the target parameter is determined as the current position of the identification part. Specifically, if the first signal intensity is greater than the second signal intensity, the first preset position is used as the current position of the identification part; if the second signal intensity is greater than the first signal intensity, the second preset position is used as the current position of the identification part.

[0154] Further, in this embodiment, in combination with Figure 3, at least two preset positions further include a third preset position. Define the line connecting the third preset position and the rotating shaft of the stirring component as the third reference line, then the third reference line is located between the first reference line and the second reference line; at least two detection modules further include a third detection module corresponding to the third preset position. Based on this, in addition to the critical positions of the target rotation range, a third detection module is also correspondingly provided at the third preset position located between two critical positions within the target rotation range. Based on the detection parameters of the third detection module, accurate measurement of the position of the identification part within the target rotation range can be achieved; in addition, when the third preset position is the initial calibration position of the identification part when the cooking device is powered on, the initial position of the stirring component when the cooking device is powered on can be accurately calibrated based on the detection parameters of the third detection module to ensure the accuracy of the rotation angle adjustment of the stirring component after power-on.

[0155] Based on this, when the first preset position is used as the above-mentioned third target position, when the recognition result is that the detection parameters of the third detection module contain the target signal, the current position of the identification part is the third preset position; when the recognition result is that the detection parameters of the third detection module do not contain the target signal, the current position of the identification part is a position other than the third preset position.

[0156] In addition, in other embodiments, when the recognition result is that the detection parameters corresponding to the first detection module, the second detection module, and the third detection module all contain the target signal, the signal intensities of the target signal in the first detection module, the second detection module, and the third detection module can be determined respectively. When the signal intensity corresponding to the third detection module is the strongest, it is determined that the current position of the identification part is the third preset position; otherwise, when the signal intensity corresponding to the third detection module is not the strongest, it is determined that the current position of the identification part is a position other than the third preset position.

[0157] Further, in this embodiment, before step S20, it further includes: determining the first preset position, the second preset position, and / or the third preset position as the target operating position.

[0158] Specifically, before step S21, the first preset position can be used as the above-mentioned first target position, and the second preset position can be used as the above-mentioned second target position to accurately represent the first position relationship, ensure the accuracy of the rotation angle regulation of the stirring component, and ensure the sealing effect of the seal.

[0159] Before step S203, the third preset position can be used as the above-mentioned third target position to accurately calibrate the initial position of the stirring component, so as to further improve the accuracy of the rotation angle regulation of the stirring component and ensure the sealing effect of the seal. Here, the third preset position can be used alone as the target operating position, or the first preset position, the second preset position, and the third preset position can be used as the target operating positions simultaneously.

[0160] In addition, in other embodiments, one of the first preset position, the second preset position, and the third preset position may also be used as the target operating position based on actual positioning requirements.

[0161] Specifically, taking at least two preset positions including the first preset position, the second preset position, and the third preset position, and at least two detection modules including the first detection module, the second detection module, and the third detection module as an example to illustrate the control scheme of the cooking device according to the embodiments of the present invention. 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 contain the 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 rotation direction or the second rotation direction. Among them, when the stirring motor rotates in the first rotation direction, when the detection parameters of the second detection module contain the target signal, it can be considered that the identification part of the stirring component reaches the second preset position. At this time, the stirring component can be controlled to switch to rotate in the second rotation 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 contain the target signal, it can be considered that the rotation angle of the stirring component reaches the target angle. At this time, the stirring component can be controlled to switch to rotate in the second rotation direction and start timing again. Based on the re-timing duration, repeat the reciprocating rotation of the stirring component controlled by the position obtained based on the duration and the detection parameters of the detection module until the operation of the stirring component reaches the target stirring duration or until a stirring end instruction from the user is received and then stop the rotation of the stirring component. Among them, before the stirring component stops rotating, when the operation of the stirring component reaches the target stirring duration or until a stirring end instruction from the user is received, the stirring component can be controlled to rotate in the first rotation direction or the second rotation direction until the detection parameters of the third detection module contain the target signal and then stop the rotation of the stirring component.

[0162] Further, based on any of the above embodiments, the target angle involved in the above embodiments can be obtained through the following scheme. Specifically, in this embodiment, the stirring component includes a stirring shaft and at least two stirring blades, and the at least two stirring blades are arranged at an angle on the stirring shaft. Based on this, the steps for obtaining the target angle include:

[0163] Step S100, obtaining the target swing angle corresponding to the stirring blade; the target swing angle is less than the set angle threshold;

[0164] The target swing angle here is specifically the target value of the angle that a single stirring blade needs to swing during the rotation of the stirring component. Wherein, 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 determined from the obtained more than one swing angles is used as the target swing angle.

[0165] The target swing angle can be a parameter set by the user, an angle determined based on the current cooking characteristic parameters of the cooking device, or an angle determined based on the stirring characteristic parameters of the stirring component. For example, different types of cooked foods can correspond to different target swing angles, and different types of cooking operations can also correspond to different target swing angles.

[0166] Step S200: Determine that the target angle is greater than or equal to the target swing angle.

[0167] Specifically, among all the 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 the set parameters input by the user can be obtained, and an angle less than the set angle threshold can be selected as the target angle based on the user's set parameters. It is also possible to select an angle less than the set angle threshold as the target angle based on the cooking characteristic parameters of the current cooking device (such as the type of cooking operation and / or the type of cooked food). For example, when the type of cooked food is solid, its target angle can be greater than when the type of cooked food is liquid.

[0168] Here, the target angle is determined through steps S100 to S200, so as to ensure that the rotation of the stirring component within the target angle can meet the operation requirements of its stirring blades. While restricting 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 for cooking.

[0169] Furthermore, in this embodiment, step S100 includes

[0170] Step S101: Obtain the total number of at least two stirring blades;

[0171] The total number here can be a parameter preset by the system, 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.

[0172] Step S102: Determine the included angle value between two adjacent stirring blades according to the total number;

[0173] Specifically, the included angle values between any two adjacent stirring blades are equal. Based on this, when the total number of stirring blades is different, the corresponding included angle values are different. Specifically, a corresponding relationship between the number of stirring blades and the included angle value can be established based on the circumferential angle, so that the total value of the included angle values 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 this corresponding relationship, the included angle value corresponding to the current total number of stirring blades can be determined.

[0174] Specifically, in this embodiment, it is defined that the total number is N and the circumferential angle is 360 degrees, then the included angle value = 360 / N.

[0175] Step S103, determine that the angular value greater than or equal to the included angle value is the target swing angle.

[0176] Among the set of angular values greater than or equal to the above-mentioned included angle value, one can be randomly selected or selected according to a preset rule as the target swing angle. Specifically, among all the angular values greater than or equal to the included angle value, one can arbitrarily select an angle less than the set angle threshold as the target swing angle, or obtain the set parameters input by the user, and select an angle less than the set angle threshold as the target swing angle based on the user's set parameters. One can also, based on the cooking characteristic parameters of the current cooking device (such as the cooking operation type and / or the type of cooked food), select an angle less than the set angle threshold as the target swing angle based on the cooking characteristic parameters. For example, when the type of cooked food is solid, its target swing angle can be greater than that when the type of cooked food is liquid.

[0177] Here, the target swing angle of the stirring blade is obtained through steps S101 to S103, so as to ensure that when the stirring assembly rotates within the target angle, at least two of its stirring blades can cooperate to achieve 360-degree stirring of the ingredients in the pot body, while limiting the torsional angle of the stirring assembly to reduce the wear of the seal and ensuring the uniformity of ingredient stirring.

[0178] Furthermore, in this embodiment, during the rotation of the stirring assembly, in addition to controlling the operation of the stirring assembly based on the position of the above-mentioned identification portion and the target operating position, the operation of the stirring assembly can also be controlled in the following manner:

[0179] Control the stirring assembly to rotate in a first direction; when the continuous duration of the rotation of the stirring assembly in the first direction is greater than or equal to the target rotation duration corresponding to the target angle, control the stirring assembly to switch to rotate in a second direction; where the first direction and the second direction are opposite. The first direction here is specifically the rotation direction of the stirring assembly corresponding to one of the first rotation direction and the second rotation direction of the above-mentioned stirring motor.

[0180] Specifically, the starting moment when the stirring assembly starts to rotate in the first direction can be the timing starting point of the continuous duration. Among them, the stirring assembly 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 can start to rotate in the first direction when it receives a set instruction (such as a stirring start instruction).

[0181] Specifically, the stirring motor can be controlled to rotate forward to make the stirring assembly rotate in the first direction; the stirring motor can be controlled to rotate backward to make the stirring assembly rotate in the second direction.

[0182] The specific target rotation duration is 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 device, the required rotation speed of the stirring component can 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 device (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 rotation of the stirring component, and can be specifically obtained by obtaining the rotation speed of the output shaft of the motor. The target rotation duration can be calculated according to the obtained rotation speed and the target angle. For example, target rotation duration = target angle / rotation speed.

[0183] Among them, after the stirring component switches to rotate in the second direction, the stirring component can stop when it runs to the set duration, or the continuous duration of the stirring component rotating in the second direction can be obtained. When the continuous duration is greater than or equal to the target rotation duration, the stirring component is controlled to rotate in the first direction again and the above steps of switching directions based on the duration are performed. Among them, the set duration can be less than or equal to the target rotation duration.

[0184] In this embodiment, the target rotation duration corresponding to the target angle is used to limit the continuous rotation duration when the stirring component rotates in a certain direction, so as to effectively avoid the excessive torsional angle of the seal in a single direction, thereby reducing the wear of the seal and ensuring the sealing performance of the pot body during the stirring process.

[0185] Among them, the method of controlling the stirring component based on the duration here and the method of controlling the stirring component based on the position of the identification part above can be selected based on the parameters input by the user. For example, two function modes can be provided for the user, and one of the modes is determined as the target mode according to the set parameters input by the user, and the stirring component is controlled to operate according to the control method of the stirring component corresponding to the target mode.
