In order to achieve the purpose of the embodiment of the invention, the embodiment of the invention provides a control method of a cooking machine, the cooking machine comprises a pot body, a motor and a stirring arm, wherein the motor is used for driving the stirring arm to swing so as to stir food materials in the pot body; as shown in fig. 1 and fig. 2, the method may include S101-S102:
s101, detecting whether the motor is locked in real time in the stirring process of the stirring arm.
Optionally, the detecting whether the motor is locked up in real time includes: and detecting whether the motor is locked according to a signal generated by a Hall sensor arranged in the motor and/or the motor current.
In the embodiment of the invention, the motor can be provided with the Hall sensor inside the motor and used for detecting the number of rotation turns of the motor in real time in the rotation process of the motor. If the hall sensor in the motor can generate signals according to a preset period, the normal operation of the motor is described, if the hall sensor in the motor cannot generate signals according to the preset period, the abnormal operation of the motor is described, and the stalling is likely to occur, therefore, whether the stalling occurs in the motor is detected according to the signals generated by the hall sensor in the motor arranged on the motor.
In the embodiment of the invention, when the motor is locked, the current of the motor is increased instantly, so that the change condition of the current of the motor can be detected in real time in the rotation process of the motor, and whether the motor is locked or not can be judged according to the change condition of the current of the motor.
In the embodiment of the invention, the two schemes can be implemented alternatively or simultaneously so as to increase the detection accuracy.
Optionally, detecting whether the motor is locked or not according to a signal generated by a hall sensor inside the motor, which is disposed on the motor, may include:
detecting signals generated by a Hall sensor in the motor in real time;
when the signals are not detected within a first preset time period or the number of the detected signals within a second preset time period is less than or equal to a preset number threshold, judging that the motor is locked; and when the signals are detected within the first preset time period or the number of the signals detected within the second preset time period is greater than the preset number threshold, judging that the motor is not locked.
In the embodiment of the invention, in the process of stirring by driving the stirring arm by the motor, the control unit of the cooking machine, such as a single chip microcomputer, can calculate the number of Hall signals generated by Hall sensors in the motor in unit time according to the preset motor rotating speed, so that whether the motor is locked up or not can be judged according to whether the signals (namely the Hall signals) are detected or not and/or the number of the signals.
In the embodiment of the invention, if no signal is detected within a certain time (such as a first preset time), which indicates that the current motor is in a running state or the running rotating speed is very low, it can be determined that the motor is locked; if the signals are detected within a certain time (such as a first preset time), the number of the detected signals can be further compared with a preset number threshold, and when the number of the signals detected within a second preset time is smaller than or equal to the preset number threshold, it indicates that the current motor is in a running state or the running speed is low, it can be determined that the motor is locked; when the number of the detected signals in the second preset time period is greater than the preset number threshold, the motor is indicated to operate at a normal rotating speed, and it can be determined that the motor is not locked.
In this embodiment of the present invention, the first preset time period may include: 100ms-120 ms; the second preset time period may include: 300ms-350 ms.
In the embodiment of the present invention, the first preset time duration and the second preset time duration may be defined according to different application scenarios, and specific values of the two preset time durations are not limited.
In the embodiment of the invention, the first preset time can be selected to be 100ms, the second preset time can be selected to be 300ms, and if the hall signal cannot be detected within 100ms or half of the hall signal detected within 300ms, the motor can be judged to be locked.
Optionally, detecting whether the locked rotor of the motor occurs according to the motor current may include:
detecting the motor current in the motor rotation process in real time;
when the motor current is greater than or equal to a preset current threshold value, judging that the motor is locked; and when the motor current is smaller than the preset current threshold value, judging that the motor is not locked.
In the embodiment of the present invention, in order to determine the real-time change condition of the motor current, the motor current detected at regular time may be compared with a preset current threshold, and the preset current threshold may indicate whether the current motor current is too large. Specifically, when the detected motor current is greater than or equal to a preset current threshold, it indicates that the current motor current is too large, and it can be determined that the motor is locked; when the detected motor current is smaller than the preset current threshold, the current motor current is in a normal range, and the motor can be judged not to be locked.
S102, when the motor is detected to be locked, after the motor is driven to rotate reversely to a set position, the rotating speed of the motor is increased, the motor is controlled to rotate forward again, and the stirring arm is driven to swing again to pass through the locked position.
In the embodiment of the present invention, after the motor is detected to have a locked-rotor by the scheme in step S101, the single chip may immediately control the motor to stop rotating and reverse, return to a set position, increase the rotation speed of the motor, and then control the motor to start forward rotation, so as to try to pass through the position where the locked-rotor has occurred, i.e., the locked-rotor position, at the accelerated rotation speed.

Optionally, the method may further include: the rotating speed of the motor is set to be a plurality of rotating speed gears in advance, and when the motor is locked, the rotating speed gears are increased step by step to increase the rotating speed of the motor.
In the embodiment of the invention, before controlling the motor to start running, the rotating speed of the motor can be divided into a plurality of rotating speed gears, and the rotating speed of the motor is set to 10 gears which are respectively S1, S2 and S3 … … S10; the cooking device can be conveniently operated by adopting different rotating speed gears according to different recipes selected by a user, thereby improving the cooking effect. In addition, when the motor is judged to be blocked in the rotating process, the motor reversely rotates and returns to the set position, the motor reversely rotates from the set position, and the single chip microcomputer automatically increases one gear or more gears on the basis of the original rotating speed gear, such as the S2 gear, such as the S3 gear, so that the problem of the blocked rotation caused by too much food materials is solved through high rotating speed.
Optionally, the method may further include: after the motor is detected to be locked, and the rotating speed of the motor is increased, when the motor is detected to be locked again, the rotating speed of the motor or the rotating speed gear of the motor is gradually increased according to a preset increasing range until the locked condition of the motor is eliminated.
In the embodiment of the invention, according to the embodiment of the tree, after the rotation speed of the motor is increased to the S3 gear, the stirring can be continued at the rotation speed of S3, and if the stirring can be successfully carried out, the rest time of the function is stirred at the speed of S3; if the rotation is also locked, the motor speed can be continuously increased by one or more gears, such as S4. In other embodiments, the rotational speed may not be increased in the form of a rotational speed gear, and the rotational speed may be increased directly according to a predetermined rotational speed increase amplitude value.
Optionally, the method may further include: and when the rotating speed of the motor is increased to a preset maximum rotating speed or the rotating speed gear is increased to a preset maximum rotating speed gear, if the locked-rotor condition of the motor is not eliminated, controlling the motor to stop rotating and carrying out fault alarm.
In the embodiment of the invention, as long as the increased rotation speed gear SX is not greater than S10, the motor can continue to increase the rotation speed to improve the torque of the stirring arm and turn the food over, and if SX is equal to S10 and the stirring is not successful, an alarm can be given to prompt the user to reduce the food materials or to perform other fault detection.
Optionally, the method may further include: and before controlling the motor to stop rotating, reducing the rotating speed of the motor so as to buffer the rotating speed of the motor.
In the embodiment of the invention, if the motor is controlled to stop rotating, the motor can be controlled to decelerate first after a motor stop command is detected, and the motor is controlled to stop so as to avoid damage to the motor caused by high-speed stop.
Optionally, the method may further include: after detecting that the motor is locked up and increasing the rotating speed of the motor, if the locked up condition of the motor is eliminated, controlling the motor to rotate at the current rotating speed.
Optionally, the method may further include:

when the motor is locked up again, the rotating speed of the motor is recovered; and when the motor is not locked again, controlling the motor to rotate at the reduced rotating speed.
In the embodiment of the invention, if the rotating speed of the motor is increased after the rotation blockage occurs, at the moment, the motor can be operated in a long length, the rotation blockage phenomenon is eliminated, and the current rotating speed is kept to operate normally for a certain time, the current rotation blockage phenomenon can be determined to be eliminated indeed, the motor is recovered to a normal state, at the moment, the rotating speed of the motor can be tried to be reduced properly in order to reduce the power consumption of the motor, if the rotating speed of the motor can still operate normally after being reduced, the reduced rotating speed can be maintained, the rotating speed can be further reduced for trying, and if the rotation speed is reduced and the rotation blockage phenomenon starts to occur, the rotation blockage can be overcome only by maintaining the higher rotating speed (if too much food materials exist), so that the rotating speed of the motor can be recovered.
