Specifically, as shown in fig. 1, the integrated cooker may include a gas range having two cookers, which may be a cooker a and an induction cooker B, respectively. The integrated stove can also comprise a range hood, and the air volume of the range hood can be divided into 3 gears, namely a low gear, a medium gear and a high gear. The integrated cooker also comprises a liftable machine head, the lifting height of the liftable machine head can be divided into 2 gears, namely 1 gear and 2 gears, and the air inlet C of the range hood is positioned on the liftable machine head.

The integrated cooker can further comprise a main control chip, and the main control chip is used for executing the control method for lifting the machine head of the integrated cooker in the following embodiment. Optionally, the main control chip may be a single chip microcomputer (MCU for short).

Based on the integrated cooker shown in fig. 1, an embodiment of the present invention provides a control method for a liftable head of the integrated cooker, fig. 2 is a flowchart of the control method for the liftable head of the integrated cooker provided in the embodiment of the present invention, and an execution main body of the embodiment of the present invention may be a main control chip, as shown in fig. 2, and specifically, the execution main body may include:

s201: detecting the cooker on the gas stove in a working state.

In this embodiment, when integrated kitchen began work, main control chip detected the mode of integrated kitchen, detected which cooking utensil in the integrated kitchen promptly and is in operating condition to the height of adjustment liftable aircraft nose.

S202: the gear of the lifting machine head is adjusted according to the cooker in the working state so as to change the height of the air inlet of the range hood.

Each cooker corresponds to one gear of the liftable machine head, the gears of the liftable machine heads are different, and the heights of the liftable machine heads are different.

In this embodiment, the corresponding relationship between different cookers and the gear of the liftable head can be preset, for example, when the cooker works, the gear of the liftable head is 1 gear; when the electromagnetic oven is used, the gear of the liftable machine head is 2. The height of the liftable machine head can be increased along with the increase of the gears, for example, the height of 2 gears of the liftable machine head is higher than the height of 1 gear.

In this embodiment, based on the corresponding relation of different cooking utensils and liftable aircraft nose gear that set up in advance, can directly adjust the gear of liftable aircraft nose according to the cooking utensil that is in operating condition to change the height of lampblack absorber air intake, realize the automatic adjustment of liftable aircraft nose height, need not artifical adjustment and can avoid the aircraft nose highly fixed of integrated kitchen to influence the oil absorption cigarette effect of lampblack absorber unchangeably.

The gear of the lifting machine head can be adjusted according to the cooker in the working state, and the method can comprise the following two implementation modes:

the first implementation mode comprises the following steps: when the number of the cookers in the working state is one, the gear of the liftable machine head is adjusted to the gear corresponding to the cooker in the working state.

In this embodiment, when only one cooker works, the gear of the liftable head is directly adjusted to the gear corresponding to the cooker in the working state according to the cooker in the working state. For example, only the machine of cooking during operation then the gear adjustment of liftable aircraft nose is the gear that the machine of cooking corresponds: 1, shifting; only electromagnetism stove during operation then adjusts the gear of liftable aircraft nose for the gear that the electromagnetism stove corresponds: and 2, gear.

The second implementation mode comprises the following steps: when a plurality of cookers in the working state are available, determining the priorities of the plurality of cookers in the working state according to a preset priority rule; and adjusting the gear of the liftable machine head to the gear corresponding to the cooker with the highest priority.

In this embodiment, when a plurality of cookers are simultaneously operating, the priorities of the plurality of cookers in the operating state are determined, and the gear of the liftable handpiece is adjusted to the gear corresponding to the cooker with the highest priority. For example, the cooking machine and the induction cooker work simultaneously, and when the priority of the induction cooker can be determined to be higher than that of the cooking machine according to the preset priority rule, the gear corresponding to the induction cooker is adjusted by the gear of the liftable machine head: and 2, gear.

The preset priority rule may be preset according to an actual application situation or experience of a person skilled in the art, and is not limited and described herein.

For example, fig. 3 is a flowchart of a control method for a liftable head of an integrated cooker according to a second embodiment of the present invention, which is different from fig. 2 in that the integrated cooker includes two cookers, namely a cooker and an induction cooker, as shown in fig. 3, the control method specifically includes:

s301: the integrated cooker starts to work.

S302: and judging the working mode of the integrated cooker. When only the cooker is turned on, executing S303; executing S304 when the cooker and the induction cooker work simultaneously; when only the induction cooker is turned on, S305 is executed.

In this embodiment, when the integrated kitchen starts to work, the main control chip detects which of the cooking machine and the induction cooker is in a working state, so as to determine the working mode of the integrated kitchen.

S303: the gear of the liftable machine head is set to be 1 gear.

In this embodiment, if only the cooker works, the liftable head selects the corresponding gear of the cooker: and 1 gear.

S304: the gear of the liftable machine head is provided with 2 gears.

In this embodiment, if the cooker and the induction cooker work together, and the priority of the induction cooker is higher than that of the cooker, the gear corresponding to the induction cooker is selected by the gear of the liftable machine head: and 2, gear.

S305: the gear of the liftable machine head is provided with 2 gears.

In this embodiment, if only electromagnetism stove work, then liftable aircraft nose gear selects the gear that the electromagnetism stove corresponds: and 2, gear.

S306: and finishing the operation of the cooker and/or the induction cooker.

S307: the range hood is delayed for 2 minutes and is shut down.

In the embodiment, after the induction cooker and the cooking machine are both closed, the liftable machine head and the range hood are automatically closed after 2 minutes of delay. Wherein, the lifting machine head is closed, namely the height of the lifting machine head is adjusted to be the lowest.

According to the control method of the liftable machine head of the integrated cooker, when the integrated cooker starts to work, the gear of the liftable machine head can be adjusted according to a cooker in a working state in the integrated cooker, so that the height of the air inlet of the range hood is changed, the automatic adjustment of the height of the liftable machine head is realized, the smoke exhaust effect is improved, the use feeling of a user is improved, manual adjustment is not needed, and the effect of oil smoke absorption of the range hood is prevented from being influenced by the unchanged height of the machine head of the integrated cooker.

Further, in the above embodiment, the integrated cooker may further include N micro switches, and each micro switch is located at a height position corresponding to each gear of the liftable handpiece.

In this embodiment, can set up a micro-gap switch in the high position department that each gear of liftable aircraft nose corresponds, whether trigger through micro-gap switch to confirm the current gear of liftable aircraft nose, and then control the liftable aircraft nose according to the current gear of liftable aircraft nose and rise or descend, so that the liftable aircraft nose adjusts to the gear that will arrive, realizes the automatic adjustment of liftable aircraft nose height.

In the embodiment, whether the micro switch is triggered or not can be determined through the open or closed state of the micro switch, and when the micro switch is in the open state, the micro switch is judged to be triggered; and when the micro switch is in a closed state, determining that the micro switch is not triggered.

Specifically, fig. 4 is a flowchart of adjusting the gear of the liftable handpiece according to the embodiment of the present invention, and as shown in fig. 4, the adjusting the gear of the liftable handpiece according to the embodiment may include:

s401: and acquiring the gear corresponding to the microswitch in the off state.

In this embodiment, after the gear to be reached by the liftable head is determined according to the cooker in the working state, when the gear of the liftable head is adjusted, the current gear of the liftable head is determined by detecting the states of all the micro switches on the liftable head. When the micro switch is in an off state, the current gear of the liftable machine head is a gear corresponding to the height position of the micro switch in the off state.

For example, the lifting height of the liftable machine head can be divided into 2 gears, namely 1 gear and 2 gears; a microswitch L1 is arranged at the height position corresponding to the 1 gear, a microswitch L2 is arranged at the height position corresponding to the 2 gear, and the current gear of the liftable handpiece can be determined to be the 1 gear or the 2 gear by detecting the states of the microswitch L1 and the microswitch L2. When the microswitch L1 is in an off state, the current gear of the liftable machine head is 1 gear; when the microswitch L2 is in an off state, the current gear of the liftable machine head is 2 gears.

S402: and comparing the gear corresponding to the micro switch in the off state with the gear to be reached by the liftable machine head so as to control the liftable machine head to ascend or descend.

In this embodiment, after determining the current gear of the liftable head according to the state of the micro switch, the current gear of the liftable head is compared with the gear to be reached, and according to the state of the micro switch, it is determined whether the current position of the liftable head is at the lower end or the upper end of the gear to be reached, if the head is below the gear to be reached, the head is directly lifted, and if the head is at the upper end of the gear to be reached, the head is continuously lowered, so that the liftable head is controlled to be lifted or lowered to the gear to be reached.

For example, taking the current gear of the liftable head as 1 gear and the gear to be reached as 2 gears, that is, the liftable head can be lifted to adjust the gear, after determining that the current gear of the liftable head is 1 gear according to the state of the microswitch, because the position where the gear 2 to be reached by the liftable head is higher than the position where the gear 1 is located, the current position of the liftable head is at the lower end of the gear 2 to be reached, the liftable head is controlled to lift, so that the liftable head can be adjusted from the gear 1 to the gear 2. The realization principle of the gear adjustment for descending of the liftable machine head is the same as that of the gear adjustment for ascending of the liftable machine head, and the description of the embodiment is omitted.

S403: detecting the closing state of a micro switch corresponding to a gear to be reached by the liftable machine head; when the micro switch corresponding to the gear to be reached by the liftable machine head is in an off state, the gear of the liftable machine head is determined to be adjusted in place.

In this embodiment, when the liftable head rises or falls to the gear to be reached, the open or close state of the micro switch corresponding to the gear to be reached by the liftable head is detected in real time, when the micro switch corresponding to the gear to be reached is in the open state, the gear of the liftable head is adjusted to the gear to be reached, and at this time, the liftable head is controlled to stop rising or falling.

For example, taking the case that the liftable head is adjusted from the 1 st gear to the 2 nd gear as an example, in the process that the liftable head is lifted from the 1 st gear, the open or closed state of the microswitch L2 corresponding to the 2 nd gear of the liftable head is detected, and when the microswitch L2 is in the open state, the gear of the liftable head is adjusted to the 2 nd gear.

According to the control method of the liftable machine head of the integrated cooker, provided by the embodiment of the invention, the micro switch is arranged at the height position corresponding to each gear of the liftable machine head, and the gear of the liftable machine head is determined through the open or close state of the micro switch, so that the automatic adjustment of the height of the liftable machine head is realized.

Further, in practical application, when integrated kitchen liftable aircraft nose rises to the top or descends to the bottom, the easy locked rotor of motor, current prior art judges whether the motor locked rotor through gathering the motor current, and judges the mode of locked rotor through gathering the motor current, only can discover when the motor locked rotor, can't avoid the locked rotor.

In order to solve the problems, the power supply of the motor is automatically cut off through the microswitch by double control of a circuit and a program algorithm, so that the rotation blockage of the liftable machine head when the liftable machine head rises to the top or falls to the bottom can be avoided. Specifically, fig. 5 is a schematic structural diagram of a micro switch provided in an embodiment of the present invention, and fig. 6 is a schematic circuit diagram of the micro switch provided in the first embodiment of the present invention, as shown in fig. 5 and fig. 6, the integrated oven may further include a bottom micro switch S1 and a top micro switch S2, the bottom micro switch S1 and the top micro switch S2 are respectively connected to two ends of the motor M1, the bottom micro switch S1 is connected in parallel to a diode D1, and the top micro switch S2 is connected in parallel to a diode D2; when the bottom microswitch S1 is in an off state, the diode D1 is reversed, and the motor stops rotating; when the top microswitch S2 is in the off state, the diode D2 reverses direction and the motor stops rotating.

In the embodiment, two diodes D1 and D2 are connected in series in a motor loop, two ends of D1 and D2 are respectively connected with a microswitch S1 and a microswitch S2 in parallel, S1 is located at the bottom of the liftable machine head, and S2 is located at the top of the liftable machine head. The lifting machine head can be driven by the motor to ascend or descend. When the motor M1 is transmitting, the liftable machine head rises, otherwise the liftable machine head falls. The motor M1 may be a push rod motor.

In this embodiment, the rotation blockage of the liftable handpiece when the liftable handpiece is lifted to the top or lowered to the bottom can be avoided by respectively detecting the open or closed states of the bottom microswitch S1 and the top microswitch S2. Specifically, based on the micro switches shown in fig. 5 and 6, the method for controlling the liftable head of the integrated cooker provided by the embodiment of the invention may further include:

detecting the closed state of the bottom microswitch S1 and the top microswitch S2; when the bottom microswitch S1 is in an off state, the motor is controlled to stop rotating so that the liftable machine head stops descending; when the top microswitch S2 is in an off state, the control motor stops rotating, so that the liftable machine head stops rising.

In this embodiment, when the liftable head rises to the top or falls to the bottom, the liftable head can trigger the bottom microswitch S1 or the top microswitch S2, after the trigger of S1 or S2, the current in the motor is segmented, and the motor stops rotating, that is, the power supply of the motor is cut off when the liftable head rises to the top or falls to the bottom, so as to control the motor to stop rotating, and the liftable head stops rising or falling, so that the motor can be controlled to stop rotating before the motor stalls, thereby not only avoiding the motor stalls, but also prolonging the service life of the motor.

As shown in fig. 5, a micro switch trigger bump 2 may be disposed on the lifting head, and when the micro switch trigger bump 2 contacts with the micro switch, the micro switch is triggered.

Specifically, after S2 is triggered, the principle that the current in the motor is segmented is specifically as follows: when the liftable machine head is lifted, the motor is in positive transmission, S2 is in a closed state at the moment, and current flows to the positive end of the motor through Mot + through S2. When the liftable machine head is lifted to the top, S2 is triggered to change from a closed state to an open state, at the moment, the diode D2 is in reverse direction and cannot be conducted, so that the current of the motor is cut off, and the motor stops rotating.

Specifically, after S1 is triggered, the principle that the current in the motor is segmented is specifically as follows: when the liftable machine head descends, the motor rotates reversely, S1 is in a closed state at the moment, and current flows to the negative end of the motor through Mot-through S1. When the liftable machine head descends to the bottom, S1 is triggered and is changed from a closed state to an open state, at the moment, the diode D1 is in reverse direction and cannot be conducted, so that the circuit of the motor is disconnected, the current of the motor is disconnected, and the motor stops rotating.

According to the control method of the liftable machine head of the integrated cooker, provided by the embodiment of the invention, the micro switches are respectively arranged at the bottom and the top of the liftable machine head, and the circuit and program algorithm are adopted for dual control, so that the power supply of the motor is automatically cut off by the micro switches when the liftable machine head is lifted to the top or is lowered to the bottom, so as to control the motor to stop rotating, and therefore, the motor can be controlled to stop rotating before the motor is locked, the motor is prevented from being locked, and the service life of the motor is prolonged.

Further, in the above embodiment, in order to reduce the number of the micro switches, the height of the top micro switch S2 may be set to be the height corresponding to the maximum gear of the liftable handpiece, that is, the top micro switch S2 is the micro switch corresponding to the maximum gear of the liftable handpiece. For example, the lifting height of the liftable machine head can be divided into 2 gears: for example, as shown in fig. 5, the bottom microswitch S1 is located at the bottom of the liftable head, the top microswitch S2 is located at the top of the liftable head, the top microswitch S2 corresponds to the height of the 2 gear of the liftable head, and the microswitch S3 corresponds to the height of the 1 gear of the liftable head.

Based on the three micro switches shown in fig. 5, the embodiment of the present invention is described by taking an example of triggering the three micro switches by a liftable handpiece, specifically, fig. 7 is a flowchart of triggering the three micro switches by the liftable handpiece provided by the embodiment of the present invention, and as shown in fig. 7, the flowchart specifically may include:

s701: the liftable head is lifted from the bottom.

In this embodiment, the liftable head is in a bottom closed state, and receives a command from the main control chip to start to lift.

S702: and judging whether the command received by the liftable machine head is 1 gear or 2 gears.

S703: it is determined whether the microswitch S3 is triggered. When the received command is 1 gear and the microswitch S3 is turned off, executing S704; when the received command is the 2 nd gear and the microswitch S3 is turned off, S704 is executed.

S704: the lifting machine head stops running.

In this embodiment, in the lifting process of the liftable head, it is determined whether the command of the main control chip is 1-gear or 2-gear, and whether the liftable head triggers the microswitch S3.

When the received command is 1 gear and the microswitch S3 is switched off, the main control chip immediately controls the liftable machine head to stop running, and the position of the liftable machine head is in 1 gear to finish the lifting work.

When the received command is 1 gear and the micro switch S3 is turned off, the main control chip controls the liftable handpiece to continuously ascend until the micro switch S3 is turned off.

S705: the liftable machine head continues to rise.

S706: it is detected whether the handpiece triggers the microswitch S2. If yes, S707 is executed. Otherwise, S705 is performed.

S707: the lifting machine head stops running.

In this embodiment, when the received command is 2 steps and the micro switch S3 is turned off, and the main control chip detects that the micro switch S3 is turned off, the main control chip controls the liftable handpiece to continue to ascend until the liftable handpiece triggers the top micro switch S2, the motor circuit is turned off, the motor stops running, and the liftable handpiece is in a 2-step position, thereby completing the ascending work.

In the embodiment shown in fig. 7, the liftable head starts to rise from the bottom, and the principle that the liftable head starts to fall from the top is the same, which is not described again in this embodiment.

Further, in the above embodiment, the micro switch may be communicated with the main control chip, so that the liftable machine head stops at the position height of the corresponding gear of the micro switch. Specifically, fig. 8 is a schematic diagram of a connection between a micro switch and a main control chip according to an embodiment of the present invention, as shown in fig. 8, when the liftable handpiece needs to reach a position height of a preset gear (for example, 1 st), the micro switch (for example, S3) at the position of the preset gear (for example, 1 st) is connected to the main control chip, when the liftable handpiece reaches the position, the micro switch S3 is changed from a closed state to an open state, and the main control chip collects a change in the micro switch S3 and then immediately turns off the drive of the motor, so that the liftable handpiece stops at the position height of the preset gear (for example, 1 st).

Further, in practical application, in the ascending or descending process of integrated kitchen liftable aircraft nose, the easy stall of motor, this embodiment accessible establishes ties a resistance in the motor return circuit, through the voltage on this circuit, can avoid integrated kitchen liftable aircraft nose to appear the stall ascending or descending in-process. Specifically, fig. 9 is a schematic circuit diagram of a micro switch according to a second embodiment of the present invention, as shown in fig. 9, based on the embodiment shown in fig. 6, the integrated cooker may further include a resistor R18, and the resistor R18 is connected to the motor in series.

In this embodiment, a resistor R18 is connected in series in the motor loop, one end of the resistor R18 is grounded, current flows to the ground through the resistor R18, the current generates voltage on the resistor R18, and the larger the current is, the larger the voltage is at the two ends of the resistor. Based on the voltage formula: the voltage V is the current I, the resistor R, and the main control chip can calculate the current I flowing through the motor M1 by collecting the voltage V at the end of the resistor R18, and knowing the resistance of the resistor R18. And then the main control chip can detect whether the motor is locked up according to the change of current from time to time, thereby effectively protecting the motor and prolonging the service life of the motor.

Specifically, fig. 10 is a flowchart of determining a locked-rotor state of a motor according to an embodiment of the present invention, and as shown in fig. 10, the method may specifically include:

s1001: the motor starts to run.

S1002: the master control chip starts to collect the voltage of the resistor R18.

S1003: and judging whether the collected voltage is greater than a preset voltage. If yes, go to S1004; otherwise, S1005 is performed.

S1004: and (5) judging the locked rotor.

S1005: if the determination is normal, the operation is continued.

In this embodiment, based on the circuit diagram shown in fig. 9, the method for controlling the lifting machine head of the integrated cooker may further include: detecting the voltage on the resistor R18, and comparing the voltage on the resistor R18 with a preset voltage; when the voltage of the resistor R18 is larger than the preset voltage, the motor is judged to be locked.

The preset voltage can be 1.2 times of the rotation voltage value of the motor when the liftable machine head is normally lifted.

Specifically, R18 is connected in series in the motor driving circuit, and when the liftable head is lifted or lowered, the current flows from the point a in fig. 9 to the ground. Because V is I R, the voltage of the point A is in direct proportion to the current flowing through R18, the voltage of the point A is collected by the main control chip at any time and is compared with the preset voltage, and when the voltage of the point A is collected to be greater than the preset voltage, the main control chip immediately stops driving of the motor to stop the operation of the liftable handpiece.

According to the control method of the liftable machine head of the integrated stove, provided by the embodiment of the invention, the resistor is connected in series in the motor loop, and the voltage value of the resistor is detected, so that the phenomenon that the liftable machine head of the integrated stove is locked during ascending or descending can be avoided, the motor is effectively protected, and the service life of the motor is prolonged.

Further, in the above embodiment, when it is determined that the motor is locked, the operation of the liftable head can be controlled to stop by the bottom microswitch S1 and the top microswitch S2. Specifically, as shown in fig. 9, a resistor R18 is connected in series to the motor through a bottom microswitch S1 and a top microswitch S2, wherein one end of the resistor R18 is respectively communicated with a first end of the bottom microswitch S1 and a first end of the top microswitch S2, a first end of the bottom microswitch S1 is an end of the bottom microswitch S1 connected in parallel with the negative electrode of the diode D1, and a first end of the top microswitch S2 is an end of the top microswitch S2 connected in parallel with the negative electrode of the diode D2.

Based on the circuit diagram shown in fig. 9, when it is determined that the motor is locked, the method may further include:

controlling at least one of the bottom microswitch S1 and the top microswitch S2 to be in an off state so as to control the motor to stop rotating; when the bottom microswitch S1 is in an off state, the diode D1 is reversed, and the motor stops rotating; when the top microswitch S2 is in the off state, the diode D2 reverses direction and the motor stops rotating.

In this embodiment, when the bottom of the motor is locked, the liftable head can trigger the bottom microswitch S1 to control the motor to stop rotating. When the top of the motor is locked, the liftable machine head can trigger a top microswitch S2 to control the motor to stop rotating.

According to the control method of the liftable machine head of the integrated cooker, provided by the embodiment of the invention, when the motor is locked, the power supply of the motor can be automatically cut off through the bottom microswitch S1 and the top microswitch S2 so as to control the motor to stop rotating, so that the motor is prevented from being locked, and the service life of the motor is prolonged.

Further, in the above embodiment, after the motor is determined to be locked and the motor is controlled to stop rotating, the motor may be controlled to commutate through the relay, so as to perform fault detection on the locked motor. Specifically, after determining that the motor is locked and controlling the motor to stop rotating, the method further includes:

controlling the motor to reversely rotate for a preset time; controlling the motor to rotate in the original direction again, detecting the voltage on the resistor R18 again, and judging whether the motor is locked; and when the continuous locked-rotor frequency of the motor is greater than the preset frequency, alarming and reminding are carried out.

In this embodiment, if the motor stall occurs, the main control chip immediately controls the motor to stop, so that the liftable machine head stops ascending or descending. Then the main control chip immediately controls the motor to rotate reversely for a preset time (2 seconds to 10 seconds) so that the liftable machine head ascends or descends for a preset distance (for example, descends by 10 CM). Wherein, control motor reversal makes liftable aircraft nose rise or descend a preset distance, its purpose is: the motor has time to rotate, and the liftable machine head also has buffer force, so that the motor has certain speed and kinetic energy when passing through the locked-rotor position before again, and the liftable machine head can smoothly pass through the locked-rotor position.

In this embodiment, after the motor rotates reversely for a preset time, the lifting machine head is executed again to raise or lower, and the motor resumes the pre-locked rotation and continues to operate, so that the lifting machine head continues to raise or lower through the locked rotation position. If the continuous preset times (such as 3 times) do not pass, the alarm is fed back to the user to remind the user of lifting the machine head, so that the user is prompted to maintain or remove the fault.

Specifically, fig. 11 is a flowchart of detecting a locked-rotor motor fault according to an embodiment of the present invention, and as shown in fig. 11, the method specifically includes:

s1101: the machine head can be lifted to start running.

S1102: and judging whether the liftable machine head is locked. If yes, go to S1103; otherwise, S1111 is executed.

S1103: the main control chip immediately controls the liftable machine head to stop running.

S1104: and judging whether the locked rotor frequency is more than 3 times. If yes, executing S1105; otherwise, S1106 is executed.

S1105: and immediately alarming to prompt a user to remove the fault.

S1106: and judging whether the state of the liftable machine head at the moment is ascending or descending. If so, go to step S1107; otherwise, S1109 is executed.

S1107: the liftable machine head runs downwards for a period of time.

S1108: the liftable head continues to ascend, and S1102 is executed.

S1109: the lifting machine head moves upwards for a period of time.

S1110: the liftable head continues to descend, and S1102 is executed.

S1111: the main control chip detects the lift head trigger S1 or S2.

S1112: and finishing the work of lifting the machine head.

In this embodiment, when the motor stalls and the number of stalled times is greater than 3 times, then report to the police and feed back to the user, remind the user liftable aircraft nose to go up and down the trouble to the suggestion user maintains or gets rid of the trouble. When the motor is locked up and the locked up rotation frequency is less than or equal to 3 times, the lifting machine head passes through the locked up rotation position again after the motor is controlled to rotate reversely for a period of time so as to detect whether the locked up rotation motor has a lifting fault.

In this embodiment, the motor may be controlled to commutate through a relay. Specifically, as shown in fig. 9, the motor commutation can be controlled by relays K7 and K8, and the specific implementation principle is as follows:

when the motor does not rotate, the 1 pin of the relays K7 and K8 is connected with the 2 pins respectively, no voltage is applied to two ends of the motor, and therefore the motor is kept static.

When the liftable machine head needs to be lifted, the 1 pin of the K8 is changed from the original 2 pins connected to the original 3 pins, namely the 1 pin of the K7 is connected with the 2 pins, and the 1 pin of the K8 is connected with the 3 pins. Because the microswitch S2 is positioned at the top end and is in a closed state, the two ends of the motor have positive voltage, the positive voltage is transmitted, and the liftable machine head starts to rise. Current flows to the ground through the R18 through the K7, the S2, the motor, the S1 and the K8. During the lifting process, the current flows through the R18 to generate voltage, the voltage generated when the current is larger, and the main control chip can judge the current of the motor according to the voltage at the end R18. When the handpiece is lifted to the top, S2 is triggered to change from the closed state to the open state, and the current of the motor is cut off because the D2 diode is reversed. The motor stops rotating immediately, and the lifting machine head stops rising.

When the liftable machine head needs to descend to the 1 st gear, the main control chip controls the relays K7 and K8 to be reversed, namely, the 1 pin of K8 is connected with the 2 pin, the 1 pin of K7 is connected with the 3 pin, the voltage at the two ends of the motor is reversed, and the current flows to the ground through the K8, the S1, the motor, the D2 and the K7 through the R18. Since the diode D2 is in the forward direction, current can flow through the diode D2 regardless of the state of S2. The motor begins to descend. When the liftable machine head triggers the S3, the main control chip detects the state change of the S3 and immediately closes the relays K7 and K8. The motor stops rotating, and the lifting machine head is kept at the 1-gear position.

According to the control method of the liftable machine head of the integrated cooker, provided by the embodiment of the invention, after the motor is judged to be locked and the motor is controlled to stop rotating, the motor can be controlled to be reversed through the relay, so that the motor locked and rotated can be subjected to fault detection, and a user is reminded of the lifting fault of the liftable machine head, so that the user is prompted to maintain or remove the fault, and the use experience of the user is improved.

For example, the lifting height of the liftable machine head can be divided into 2 gears: 1 st gear and 2 nd gear, the bottom micro switch S1 is located at the bottom of the liftable head, the top micro switch S2 is located at the top of the liftable head, and the top micro switch S2 corresponds to the height of 2 nd gear of the liftable head, the micro switch S3 corresponds to the height of 1 st gear of the liftable head as an example, fig. 12 is a flow chart of a control method of the liftable head of the integrated cooker provided by the third embodiment of the present invention, which is different from fig. 2 in that the present embodiment adds the judgment of the rotation blockage of the liftable head, as shown in fig. 12, it specifically may include:

When the liftable machine head needs to be closed, executing S1202; executing S1205 when the lifting machine head 1 gear needs to be opened; when the liftable machine head needs to be opened in the 2 nd gear, S1214 is executed.

S1202: and judging whether the liftable machine head is locked. If yes, go to S1203; otherwise, S1204 is executed.

In this embodiment, the lifting machine head rotation blocking means that the lifting machine head cannot ascend or descend under the driving of the motor. The lifting machine head is driven by the motor to ascend or descend, so that the lifting machine head can be locked up and locked down by the motor.

S1203: the motor enters a locked-rotor state.

In this embodiment, the motor entering the locked state may include the motor stopping rotation controlled by the bottom microswitch S1 and the top microswitch S2 in the above embodiments, and the motor performing fault detection on the locked position by reversing.

S1204: the motor rotates reversely, and the liftable machine head falls to the bottom.

S1205: it is detected whether the motor is running. If yes, go to S1206; otherwise, S1207 is performed.
