In one example of the present invention, determining whether the pan needs to enter a position searching action according to the first gesture position includes: under the condition that the first posture position is at the target position, judging that the pot body does not need to enter the position to search for the action; and/or under the condition that the first posture position is at the first position, judging that the pot body needs to enter the position searching action; and/or under the condition that the first gesture position is at the second position, judging that the pot body needs to enter the position searching action.

Compared with the prior art, the technical effect achieved by adopting the technical scheme is as follows: when the first posture position is at the target position, the pan body is at the target position (the target position is the initial position of the system) at the moment, so that the pan body does not need to enter a position searching action to carry out subsequent steps; when the first posture position is at the first position (the first position is the positive position of the system) or the second position (the second position is the negative position of the system), the pot body is not at the initial position of the system, so that the pot body needs to enter the position searching action.

After the technical scheme of the invention is adopted, the following technical effects can be achieved:

(1) The first gesture position of the pot body can be automatically detected, particularly, the first gesture position of the pot body is judged through the connection state of the third switch and the first switch, manual detection is not needed, time and labor are saved, and the detection accuracy can be improved;

In a specific embodiment, since most of the existing methods for searching the initial position of the pot 300 use the motor hall sensor to count, and the hall value of the initial position is calibrated in factory, the method requires manual calibration when powering on and running to the designated position, which is time-consuming and labor-consuming and cannot be commonly used when different pot 300 are replaced. The application provides a detection device for a cooking machine 10, which can automatically detect a first gesture position of a pan body 300, does not need manual detection, saves time and labor and can improve detection accuracy. The detecting device comprises a position sensor and a main control board 120, wherein the position sensor is provided with a third contact pin 113 and a first contact pin 111, the main control board 120 is provided with a COM4 port 124 and a COM1 port 121, the COM4 port 124 and the third contact pin 113 form a third switch, and the COM1 port 121 and the first contact pin 111 form a first switch; the on state of the third switch is determined by whether the third contact pin 113 is in contact with the COM4 port 124, and the on state of the first switch is determined by whether the first contact pin 111 is in contact with the COM1 port 121. The third switch and the first switch are connected in series on the main control loop, the main control loop is arranged on the main control board 120, and the on-off state of the main control loop can be controlled through the on states of the third switch and the first switch: only when the third switch and the first switch are both on, the on-off state of the main control loop is a conducting state; when only one of the third switch and the first switch is on, the on-off state of the main control loop is off. Determining a first posture position of the pot 300 according to the on-off state: when the on-off state is the on state, the main control loop can output a signal (the signal is a first signal at the moment) to the main control board 120, and the main control board 120 judges that the current pot body 300 is at a first position according to the received first signal, and the first gesture position is the first position; when the on-off state is the off state, the main control loop cannot output a signal to the main control board 120, and the current pan body 300 is judged to be at the target position, and the first gesture position is the target position.

Preferably, in the present embodiment, the on state of the third switch may be always on. When the third switch is always turned on, the first posture position of the pan body 300 can be determined by the on states of the first switch and the second switch, so that the detection steps of the detection device can be further reduced, and the detection efficiency can be improved.

Preferably, referring to fig. 2 to 4, the relationship between the three contact pins (the first contact pin 111, the second contact pin 112 and the third contact pin 113) on the position sensor and the three ports (COM 1, COM2 and COM 4) on the main control board 120 when the pot 300 is at the first position, the second position and the target position is shown in schematic views.

Preferably, referring to fig. 7, which is a schematic diagram of a system structure of a motor driving circuit and a hall sensor in a third embodiment of the present invention, a detailed driving manner of the motor driving circuit is as follows: when the singlechip needs to drive the motor 400 to rotate forward, the Hin1_3 pin outputs a PWM pulse signal, the Lin1_3 pin outputs a high level, and the Hin2_3 pin and the Lin2_3 pin simultaneously output a low level. After the signals pass through the U5 chip, the original 3V signals are boosted to 5V signals, so that the Hin1_5 pin outputs 5V PWM pulse signals, the Lin1_5 outputs 5V high level, and the 3V and 5V power supplies are isolated, thereby ensuring that the signals of the two power supply domains cannot be influenced mutually and generating high-frequency noise. The pulse signal of hin1_5 is boosted to 30V again through the U3 chip, and outputted through ho_m1, and the high level of lin1_5 is inverted to the low level by the U3 chip and outputted through lo_m1. The low level signal of lin2_5 is outputted by U4 through lo_m2 in reverse direction, and is boosted to 12V high level. At this time, ho_m1 is a PWM pulse signal, lo_m1 and ho_m2 are low level, and lo_m2 is high level, so that Q2 is intermittently turned on, Q1 and Q4 are turned off, Q3 is turned on, current flows from the positive electrode of the first power supply through Q2, flows from M1, flows out through M2 after passing through the motor, flows into the ground of the power supply after passing through Q3, forms a closed loop, and makes the motor rotate forward. When the speed is required to be regulated, the speed of the driving motor 400 can be accelerated and slowed down only by changing the duty ratio of the PWM pulse. The chips U3 and U4 have the functions of lifting voltage to drive the Q1, Q2, Q3 and Q4 switches and preventing the Q2 and Q4 or the Q1 and Q3 from being simultaneously opened so as to cause the power supply to be short-circuited.

Similarly, when the driving motor 400 needs to be reversed, the hin2_3 pin outputs a PWM pulse signal, lin2_3 outputs a high level, and the hin1_3 and lin1_3 pins simultaneously output a low level. After the signals pass through the U5 chip, the original 3V signals are boosted to 5V signals, so that the Hin2_5 pin outputs 5V PWM pulse signals, the Lin2_5 pin outputs 5V high level, and the 3V and 5V power supplies are isolated, so that the signals of the two power supply domains are ensured not to be influenced mutually, and high-frequency noise is generated. The pulse signal of hin2_5 is boosted to 30V again through the U4 chip, and outputted through ho_m2, and the high level of lin2_5 is inverted to the low level by the U4 chip and outputted through lo_m2. The low level signal of lin1_5 is outputted by U3 in reverse direction through lo_m1, and is boosted to 12V high level. At this time, ho_m2 is a PWM pulse signal, lo_m2 and ho_m1 are low level, and lo_m1 is high level, so that Q1 is intermittently turned on, Q2 and Q3 are turned off, Q4 is turned on, current flows from the positive electrode of the first power supply through Q1, flows from M2, flows out through M1 after passing through the motor, flows into the power ground after passing through Q4, forms a closed loop, and inverts the motor. When the speed is required to be regulated, the speed of the driving motor 400 can be accelerated and slowed down only by changing the duty ratio of the PWM pulse.

When the driving motor 400 rotates, once hall signals of the hall sensor can be triggered every time a certain angle is rotated, the hall signals can be received and processed by the controller, so that the running distance of the driving motor 400 can be calculated, and the minimum value is 1 hall value: when the driving motor 400 rotates, hall signals are input to the hr_a_5 and the hr_b_5 through the COM2 port 122, instantaneous shaking signals are removed through a pair of capacitance resistors, noise is reduced, the 5V hall signals are reduced to 3V through the chip U6, the 3V hall signals are input to the hr_a_3 and the hr_b_3 hall signals and processed by a controller (a single chip microcomputer in the embodiment), wherein the U6 is adapted to be reduced in voltage, besides the power supply of the single chip microcomputer, the power supplies of 3V and 5V can be isolated, so that external interference sources can not be transmitted to the single chip microcomputer, and the single chip microcomputer is interfered to analyze the hall signals.

In the control of the pan body 300 of the cooker 10, a certain point in the whole gesture control stroke is taken as an initial position, the front of the initial position is defined as a gesture positive position, and the rear is defined as a gesture negative position. Referring to fig. 8, which is a schematic diagram of a system structure of a position sensor according to a second embodiment of the present application, a stylus type position sensor is used in the present application, such that when a pan body 300 is in a positive position, a first stylus 111 contacts a system ground (a negative electrode of a power supply), a second stylus 112 is disconnected from the system ground, and when the pan body 300 is in a negative position, the posture is opposite; when the pot 300 is in the initial position, both the first contact pin 111 and the second contact pin 112 are systematically disconnected. The three contact pin type position sensors are connected into a circuit through COM4, and are pulled up to 5V through resistors, so that when the contact pins are not connected with the system ground, the high level of CD_1, CD_2 and CD_3 is ensured to be 5V. U9, U10, U12 step down the initial 5V signal of contact pin to the 3V signal that singlechip can handle to keep apart 3V and 5V power, make outside 5V noise can not influence the signal processing of singlechip. If the posture of the pot 300 at the initial position needs to be changed, the main control board 120 contacted by the contact pins is only required to be adjusted, and the two contact pins are rotated to align the required positions with the systematically disconnected positions.

[ Example IV ]

The embodiment provides a control method for a cooking machine, which is applied to a detection device for the cooking machine in embodiment one, and comprises the following steps:

acquiring a first posture position of the pot body;

judging whether the pot body needs to enter a position searching action according to the first gesture position;

Under the condition that the pot body is judged to need to enter the position to search for the action, the driving motor is controlled to operate so as to obtain a second posture position of the pot body, and the second posture position is positioned at the target position;

when the second posture position is at the target position, the position finding action is exited.

In a specific embodiment, since most of existing methods for searching an initial position of a pot body use motor hall sensors to count, factory calibrate hall values of the initial position, power-on and power-on are performed to reach a designated position, the method requires manual calibration, is time-consuming and labor-consuming, and cannot be commonly used when different pot bodies are replaced. In order to enable a pot body of the cooking machine to be located at a target position (the target position is a system initial position), specifically, a first posture position of the pot body can be detected through on-off of a first switch, a second switch and a third switch, after the first posture position of the pot body is detected, a driving motor is required to be controlled to operate according to the first posture position so that the pot body is located at the target position, the initial position of the pot body is not required to be manually calibrated, and the system initial position is automatically found when the cooking machine is powered on, so that time and labor are saved; meanwhile, the automatic cooker is self-adaptive to various cooker models, the replacement and change of the cooker body does not influence the initial position of a system found by the cooker, so that the cooker body does not need to be manually calibrated after being replaced, and only needs to be electrified again, and the cooker automatically calibrates the initial position of the system.

The specific flow for judging whether the pot body needs to enter the position searching action is as follows: when the cooker is electrified, a first gesture position of the cooker body is obtained, and whether the cooker body needs to enter a position searching action can be judged according to the first gesture position. When the first posture position is at the target position, the pan body is at the target position (the target position in the embodiment is the initial position of the system), so that the pan body does not need to enter the position searching action to carry out subsequent steps; when the first posture position is at the first position (the first position is the positive position of the system in this embodiment) or the second position (the second position is the negative position of the system in this embodiment), it indicates that the pan body is not at the initial position of the system at this time, so the pan body needs to enter the position searching action.

The flow of the position finding action is: when the pot body needs to enter a position searching action, controlling a driving motor to operate so as to drive a position sensor to rotate, updating first information of the position sensor in real time, acquiring a second posture position of the pot body according to the first information updated in real time, and enabling the second posture position to be at a target position, wherein the posture position of the pot body is at the target position (namely a system initial position) until the system searching initial position is finished, and finishing system initialization; in the case where the second pose position is at the target position, the position finding action may be exited.

In this embodiment, the target position is a system initial position, the first position is a positive position of the system, and the second position is a negative position of the system. The running direction of the driving motor may be any direction as long as the target position is found out in the end. The first gesture position is a gesture position of the pot body detected when the control system is powered on, and can be expressed as a gesture position at a first moment; the second gesture position is a gesture position of the pot body detected in real time after the pot body enters the position searching action, and can be expressed as a gesture position at a second moment.

In general, under the condition that the first gesture position is at the first position, the driving motor is controlled to run in the second direction; and when the first posture position is at the second position, controlling the driving motor to run in the first direction. The first position and the second position are defined according to the target position, the first position is located in a first direction of the target position, the second position is located in a second direction of the target position, and the first direction is opposite to the second direction. Under the condition that the first posture position is at the first position, controlling the driving motor to run in the second direction, so that the pot body in the first direction also runs in the second direction until the pot body passes through the target position; when the first posture position is at the second position, the driving motor is controlled to operate in the first direction, so that the pot body in the second direction also operates in the first direction until the pot body passes through the target position. In this embodiment, the first direction is a positive direction, and the second direction is a negative direction.

Preferably, when the driving motor rotates, the hall sensor can be triggered once by a certain angle, and the hall signal can be received and processed by the controller, so that the running distance of the driving motor can be calculated, and the minimum is 1 hall value.

Preferably, the control method may also directly enter the position searching action after the first gesture position of the pot body is obtained, no matter the specific situation of the first gesture position: judging that the pot body is at the target position under the condition that the first gesture position is at the target position, and exiting the position searching action; and under the condition that the first posture position is not at the target position, controlling the driving motor to operate so as to obtain a second posture position of the pot body, and enabling the second posture position to be at the target position.

Further, under the condition that the pan body is judged to need to enter the position to search for the action, the driving motor is controlled to operate so as to obtain a second posture position of the pan body, and the second posture position is located at the target position, and the method comprises the following steps:

under the condition that the pan body is judged to enter the position to search for the action, controlling the operation of the driving motor according to the first posture position;

detecting and updating the first gesture position in real time to obtain a second gesture position until the second gesture position is at the target position;

Recording the mark position of the driving motor when the second gesture position is at the target position;

and controlling the driving motor to run to the marking position.

Specifically, the specific flow of the position finding action is: when the pot body needs to enter the position to search for action, the running direction of the driving motor is judged and controlled according to the first posture position, the movement of the pot body is driven by the movement of the driving motor (namely, the pot body moves along with the movement of the driving motor in the running process of the driving motor), the position sensor is fixed on the pot body and moves along with the movement of the pot body, so that the posture position of the pot body is changed, the first information of the position sensor is updated in real time, the second posture position of the pot body is obtained according to the position sensor updated in real time, whether the second posture position reaches the initial position of the system is judged in real time, the marked position of the driving motor is recorded when the second posture position reaches the initial position of the system when the second posture position is at the initial position of the system, and the detection device searches the initial position of the system of the pot body. After the initial system position is found, the driving motor is driven to run to the marking position according to the marking position of the driving motor, so that the posture position of the pot body is located at the target position (namely the initial system position), and the detection device finishes finding the initial system position until the initial system position is found, and the system initialization is completed.

Preferably, after recording the mark position of the driving motor when the second posture position is at the target position, the control method may further include: marking the mark position as a target position, and recording a Hall value H at the moment; controlling the driving motor to slow down to a complete stop; controlling the driving motor to run to a coordinate point with a Hall value of H according to the first gesture position; resetting the coordinate system, taking the current position as a Hall value 0, exiting the position searching action, ending the searching of the initial position of the system, and finishing the system initialization.

Further, controlling the driving motor to operate to the marking position includes:

Controlling the driving motor to slow down to a complete stop;

and controlling the driving motor to operate to the marking position according to the first gesture position.

Specifically, when the second gesture position is recorded to be at the target position, after the mark position of the driving motor (i.e. after the initial position of the system is found), the driving motor is controlled to slow down to a complete stop because the characteristic of the driving motor cannot immediately stop running, and after the driving motor is completely stopped, the driving motor is caused to run towards the direction of the initial position of the system and stop to the mark position, at the moment, the gesture position of the pot body is at the target position (i.e. the initial position of the system), so that the control system finishes searching the initial position of the system, and the system initialization is finished.

Further, judging whether the pan body needs to enter a position searching action according to the first gesture position comprises the following steps:

under the condition that the first posture position is at the target position, judging that the pot body does not need to enter the position to search for the action; and/or

Judging that the pot body needs to enter a position searching action under the condition that the first posture position is at the first position; and/or

And under the condition that the first posture position is at the second position, judging that the pot body needs to enter the position searching action.

Specifically, when the first posture position is at the target position, the pan body is at the target position (the target position is the initial position of the system) at the moment, so that the pan body does not need to enter a position searching action to carry out subsequent steps; when the first posture position is at the first position (the first position is the positive position of the system) or the second position (the second position is the negative position of the system), the pot body is not at the initial position of the system, so that the pot body needs to enter the position searching action.

The steps of a specific control method can be simplified as a whole: ① Powering up the cooker, and initializing a position sensor by a controller; ② Reading first information of the position sensor, and processing the first information to obtain whether the current posture position of the pot body is at the positive position, the negative position or the initial position of the system; ③ If the posture position of the pot body is at the initial position of the system, the searching for the initial position is finished, and the system initialization is completed; if the system is in a positive position, controlling the driving motor to run in a negative direction at a minimum speed, and detecting a change of the position sensor; if the motor is in the negative position of the system, controlling the driving motor to run in the positive direction at the minimum speed, and detecting the change of the position sensor; ④ When the first stylus and the second stylus of the position sensor are read out and disconnected with the system at the same time, marking the initial position of the system, remembering the current Hall value, and assuming H; ⑤ Controlling the driving motor to slow down to a complete stop; ⑥ Controlling the driving motor to run to a coordinate point with a Hall value of H in the opposite direction, and stopping; ⑦ Resetting the coordinate system, taking the current position as a Hall value 0, exiting the position searching action, ending searching the initial position of the system, and finishing the system initialization.
