Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The embodiment of the application provides air conditioning equipment and a control device of a swing motor thereof, so that the running reliability of an air conditioner is improved. The air conditioner and the control device of the swing motor thereof will be explained with reference to the accompanying drawings.

An embodiment of the present application provides an air conditioning device, and specifically, refer to fig. 1, where fig. 1 is a schematic structural diagram of the air conditioning device provided in the embodiment of the present application. The air conditioner 1 may be a variable frequency air conditioner or a fixed frequency air conditioner, and the air conditioner 1 may be a floor type air conditioner, a wall type air conditioner, a central air conditioner, or the like. The air conditioning equipment 1 provided by the embodiment of the application comprises a wind swinging motor 10 and a control device 20 of the wind swinging motor, wherein the wind swinging motor 10 is electrically connected with the control device 20 of the wind swinging motor, and the control device 20 of the wind swinging motor is used for controlling the wind swinging motor 10 so that the wind swinging motor 10 can normally run. The control device 20 of the yaw motor can also obtain feedback of the yaw motor 10 so that the air conditioning system 1 can monitor the operating state of the yaw motor 10. The swing motor 10 is used for controlling the blades of the air conditioning equipment 1 to swing, and then the fan of the air conditioning equipment 1 can blow air into a space outside the air conditioning equipment 1 through a gap formed by the swinging of the blades, so that a user can feel the air outlet effect of the air conditioning equipment 1 at different angles. Therefore, the normal operation of the wind swing motor 10 plays a great role in the cooperation with the fan and the normal operation of the fan blades.

In order to more clearly describe the control device 20 of the wind turbine generator and the control process thereof, the following description will be made in terms of the control device 20 of the wind turbine generator and the control method of the wind turbine generator, respectively.

Referring to fig. 2 in conjunction with fig. 1, fig. 2 is a schematic structural diagram of a control device of a swing motor in the air conditioning equipment shown in fig. 1. The control device 20 of the swing motor includes an inner main chip 22, a switching circuit 24, and a detection circuit 26. The conversion circuit 24 is electrically connected to the internal main chip 22, and the conversion circuit 24 is configured to convert the control signal sent by the internal main chip 22 into a driving signal. The output end of the switching circuit 24 is electrically connected with the swing motor 10 so that the inner main chip 22 controls the swing motor 10 through a driving signal. One end of the detection circuit 26 is electrically connected to the internal main chip 22, and the other end of the detection circuit 26 is electrically connected to the output end of the conversion circuit 24. The detection circuit 26 is used for acquiring a feedback signal after the conversion circuit 24 is electrically connected with the swing motor 10, and transmitting the feedback signal to the inner main chip 22. By arranging the detection circuit 26 capable of detecting the operation state of the wind oscillating motor 10, the inner main chip 22 can monitor the operation state of the wind oscillating motor 10 in real time according to the feedback signal transmitted by the detection circuit 26.

The internal machine main chip 22 is disposed in an internal machine of the air conditioner 1 to control operation of the internal machine of the air conditioner 1. The air conditioner 1 is generally divided into an indoor unit and an outdoor unit, and the indoor unit and the outdoor unit are disposed at different positions to perform different functions. The swing motor 10 and the control device 20 of the swing motor in the embodiment of the present application are both disposed in an indoor unit to control the operation of the indoor unit of the air conditioning equipment 1.

The conversion circuit 24 can be understood as a logic level conversion circuit, that is, a control signal sent by the internal main chip 22 is converted into a driving signal and sent to the swing motor 10, so as to control the operation of the swing motor 10.

The detection circuit 26 is disposed between the inner main chip 22 and the swing motor 10, a control signal sent by the inner main chip 22 is converted into a driving signal through the conversion circuit 24, and the detection circuit 26 can obtain a feedback signal after the conversion circuit 24 is connected with the swing motor 10 and transmit the feedback signal to the inner main chip 22. Therefore, the running state of the swing motor 10 is detected, and the inner machine main chip 22 can monitor the running of the swing motor 10.

The internal main chip 22 can be used to determine the abnormal condition of the feedback signal. For example, when it is determined that the feedback signal is abnormal, the swing motor 10 is controlled to stop and an alarm signal is output. When the feedback signal is within the first preset range, it is determined that the feedback signal is normal, and the working mode of the wind-swinging motor 10 is obtained. When the swing motor is in the first working mode, the swing motor 10 is controlled to operate within a first angle range. The first mode of operation can be understood as a normal mode of operation, i.e. without special requirements of the user. Wherein the feedback signal is a pulse width modulation signal. The abnormality of the feedback signal may be understood as determining whether the fed back pwm signal is within a first preset range, and determining that the feedback signal is abnormal if the fed back pwm signal is 0 or the fed back pwm signal is not within the first preset range. If the fed back pulse width modulation signal is within a first preset range, the feedback signal is determined to be normal, and then the swing wind motor 10 is controlled to operate within a first angle range. For example, the first preset range, that is, the duty ratio of the pulse width modulation signal, may be 0.4 to 0.6, and when the duty ratio of the fed back pulse width modulation signal is 0.8 or 0.2, that is, the feedback signal is not within the first preset range, it may be determined that the feedback signal is abnormal. The duty cycle of a pwm signal is the proportion of the time that the power is on relative to the total time in a pulse cycle. The Duty cycle (Duty Ratio) has the following meaning in the field of telecommunications: for example: the pulse width is 1 mus and the duty cycle of the pulse sequence is 0.25 for a signal period of 4 mus. It should be noted that, when the yaw motor 10 is controlled to start up and operate, the operation angle of the yaw motor 10 may be understood as an angle within the first angle range. When the pwm signal fed back from the detection circuit 24 is normal, the wind turbine 10 is controlled to operate normally, that is, to continue to operate within the first angle range according to the original operation.

It should be noted that the inner main chip 22 sends a control signal, which is converted into a driving signal by the conversion circuit 24 and sent to the swing motor 10, and when the feedback signal detected by the inner main chip 22 matches the sent control signal, it can be determined that the swing motor is operating normally. When the feedback signal detected by the inner main chip 22 deviates from the sent control signal, it can be understood that the feedback signal of the swing motor 10 affects the driving signal of the conversion circuit 24, for example, the feedback signal of the swing motor 10 lowers the duty ratio of the driving signal of the conversion circuit 24, so that the feedback signal of the detection point detected by the inner main chip 22 deviates from the sent control signal, and it can be determined that the operating angle of the swing motor 10 deviates from the preset value, and then the inner main chip 22 adjusts the duty ratio of the output control signal according to the deviation to correct the deviation.

When the swing wind motor 10 is in the second working mode, the inner machine main chip 22 determines whether the feedback signal is within a second preset range. The second mode of operation may be understood as the mode of operation when the user has a particular need. When the feedback signal exceeds the second preset range, the inner main chip 22 adjusts the driving signal and outputs the adjusted driving signal to the wind-swinging motor 10 so that the wind-swinging motor 10 operates in the second angle range. The second preset range is within the first preset range and smaller than the first preset range, and the second angle range is within the first angle range and smaller than the first angle range. It should be noted that the endpoint value of the second preset range is within the first preset range, and the second preset range is smaller than the first preset range. The endpoint value of the second angular range is also within the first angular range, and the second angular range is less than the first angular range. It should be noted that, according to the feedback signal fed back by the detection circuit 26 provided in the embodiment of the present application, it may be determined whether the operation of the swing wind motor 10 is normal according to the feedback signal, and after it is determined that the operation of the swing wind motor 10 is normal, it is determined whether the operation of the swing wind motor 10 meets the use requirement of the user, and when the feedback signal is within the first preset range but not within the second preset range, it may be determined that the operation of the swing wind motor 10 is normal and meets the use requirement of the user, and at this time, the inner machine main chip 22 controls the swing wind motor 10 to operate within the second angle range. When the feedback signal is within the second preset range, it can be determined that the operation of the swing wind motor 10 is normal but does not meet the use requirement of the user, and at this time, the internal machine main chip 22 controls the swing wind motor 10 to operate within the second angle range so as to meet the use requirement of the user. The second angle range may be a second angle range corresponding to different modes pre-stored in the internal main chip 22, or may be a second angle range input to the internal main chip 22 according to a swing angle required by a user.

The driving signal is a pulse width modulation signal, and the inner main chip 22 adjusts a duty ratio of the pulse width modulation signal and outputs the adjusted pulse width modulation signal to the wind-swinging motor 10 so that the wind-swinging motor 10 operates at a second angle. It will be appreciated that the duty cycle of the pwm signal is modulated to cause the operation of the wind-oscillating motor 10 at a desired operating angle.

It can be understood that the inner main chip 22 outputs a control signal to the conversion circuit 24, and the control signal is converted into a driving signal by the conversion circuit 24 and output to the swing motor 10 to control the swing motor 10, and meanwhile, the detection circuit 26 detects the actual operation condition of the swing motor 10 and sends a feedback signal to the inner main chip 22. The internal main chip 22 detects the actual operation condition of the swing motor 10 through the detection circuit 26, and when detecting that the swing motor 10 fails to work normally, the air conditioning equipment 1 is shut down and an alarm signal is output, so that a user can know that the air conditioning equipment 1 is abnormal in operation, and the air conditioning equipment 1 is reliable in operation. When detecting that the operation angle has deviation with the requirements of the user, the inner machine main chip 22 corrects the angle deviation of the wind swinging motor by adjusting the pulse width modulation signal output duty ratio in real time, and the user experience is improved.

It should be noted that the control device 20 of the swing motor provided in the embodiment of the present application may further include an interface seat, for example, please refer to fig. 3 in combination with fig. 1, and fig. 3 is another schematic structural diagram of the control device of the swing motor in the air conditioning equipment shown in fig. 1. The interface socket 28 may be understood as a socket. One interface of the interface seat 28 is connected to the output end of the switching circuit 24 in a plug-and-pull manner, and the other interface of the interface seat 28 is connected to the interface of the wind-swinging motor 10 in a plug-and-pull manner, it can be understood that the state that the switching circuit 24 is electrically connected to the wind-swinging motor 10 through the interface seat 28 can be realized only when the output end of the switching circuit 24 is plugged into the interface seat 28 and the interface of the wind-swinging motor 10 is plugged into the interface seat 28 at the same time, so that the switching circuit 24 can transmit a signal to the wind-swinging motor 10 to control the wind-swinging motor 10.

In order to more clearly describe the process of the control device 20 of the wind turbine generator for detecting the operation state of the wind turbine generator 10, the detection circuit 26 in the control device will be described below.

For example, referring to fig. 4 in conjunction with fig. 3, fig. 4 is a schematic structural diagram of a circuit in the control device of the wind-swinging motor shown in fig. 3. The detection circuit 26 includes a transistor Q, a first resistor R1, a second resistor R2, a third resistor R3, a fourth resistor R4, and a fifth resistor R5. The triode Q comprises a base electrode Q1, an emitting electrode Q2 and a collector electrode Q3. Collector Q3 is electrically connected to power supply VCC1 of inner main chip 22. One end of the first resistor R1 is electrically connected with the base electrode Q1, and the other end of the first resistor R1 is electrically connected with one end of the second resistor R2. The other end of the second resistor R2 is electrically connected to the output terminal OUT4 of the conversion circuit 24. One end of the third resistor R3 is electrically connected to the other end of the first resistor R1, and the other end of the third resistor R3 is electrically connected to the ground. One end of the fourth resistor R4 is electrically connected to the signal acquisition end P1.3 of the inner main chip 22, and the other end of the fourth resistor R4 is electrically connected to the emitter Q2. One end of the fifth resistor R5 is electrically connected to the other end of the fourth resistor R4, and the other end of the fifth resistor R5 is electrically connected to the ground.

The inner machine main chip 22 includes a power source VCC, a signal output end P1.7, a signal acquisition end P1.3, and a ground end GND, the power source VCC is used for powering on the inner machine main chip 22, and the voltage value of the power source VCC is VCC1. The signal output end P1.7 is used for outputting signals, and the signal acquisition end P1.3 is used for acquiring signals.

The conversion circuit 24 includes an input pin IN1, a ground terminal VSS, an output pin OUT4, and a power supply VDD. The input pin IN1 is used for receiving an input signal, and the output pin OUT4 is used for outputting a signal. The voltage value of the power supply VDD is VCC2, and the voltage value of the power supply VCC of the inner main chip 22 is different from that of the power supply VDD of the conversion circuit 24. The input pin IN1 is connected to the signal output terminal P1.7 of the internal main chip 22.

The interface socket 28 includes an interface 1 and an interface 5, where the interface 1 is used for connecting to the power source VCC2, and the interface 5 is used for connecting to the output pin OUT4 of the conversion circuit 24.

It can be understood that the second resistor R2 and the third resistor R3 constitute a voltage dividing and current limiting module of the detection circuit 26. The transistor Q may be understood as a switching block of the detection circuit 26. When one end of the second resistor R2 close to the interface seat 28 receives a high level from the wind swinging motor 10, a new voltage value is formed through voltage division of the second resistor R2 and the third resistor R3, the high level forms a current through the second resistor R2 and the third resistor R3, the high level also forms a current conduction triode Q through the second resistor R2 and the first resistor R1, and a high level signal is input to a signal acquisition end P1.3 of the inner machine main chip 22 through the fourth resistor R4, at the moment, the inner machine main chip 22 receives a high level signal fed back from a detection point connected with the conversion circuit 24 and the wind swinging motor 10 and compares the high level signal with a control signal sent by the inner machine main chip 22, and when the high level signal is the same as or approximately the same as the control signal, the wind swinging motor 10 is judged to normally operate. When one end of the second resistor R2 close to the interface seat 28 receives a low level from the swing motor 10, the triode Q is not turned on by the low level, and then the signal acquisition end P1.3 of the internal machine main chip 22 receives a low level signal fed back from a detection point connected with the conversion circuit 24 and the swing motor 10, and when the low level signal is different from the control signal, it is determined that the swing motor 10 is abnormal in operation.

interfaces

It should be noted that, when the swing motor 10 operates normally, the signal acquisition terminal P1.3 of the internal machine main chip 22 acquires a normal PWM signal, and at this time, the air conditioning equipment 1 operates normally. When the output of the swing motor 10 is abnormal, the signal acquisition end P1.3 of the inner main chip 22 cannot acquire a signal, and the inner main chip 22 outputs a shutdown alarm. When the inner main chip 22 detects that the operating angle of the wind swing motor 10 deviates from the pre-stored second angle, the inner main chip 22 calibrates the operating angle of the wind swing motor 10 by adjusting the PWM output duty ratio, so that the wind swing motor 10 operates according to the second angle.

The control device 20 of the swing motor includes an inner main chip 22, a switching circuit 24, and a detection circuit 26. The inner main chip 22 is electrically connected to the conversion circuit 24, one end of the detection circuit 26 is electrically connected to the inner main chip 22, and the other end of the detection circuit 26 is electrically connected to the output end of the conversion circuit 24. The output end of the conversion circuit 24 is electrically connected with the swing motor 10. The control method of the swing wind motor comprises the following steps:

101. the inner machine main chip controls the operation of the wind swing motor through a conversion circuit.

The internal main chip 22 sends a control signal to the conversion circuit 24, the control signal is converted into a driving signal through the conversion circuit 24, and the conversion circuit 24 sends the driving signal to the swing motor 10 to control the operation of the swing motor 10. The driving signal may be a pulse width modulation signal, and the operation of the wind turbine 10 at different operation angles is controlled by sending duty ratios of the pulse width modulation signals of different driving signals.

102. And the inner machine main chip determines whether a feedback signal after the conversion circuit is electrically connected with the wind swing motor is abnormal.

The detection circuit 26 transmits a feedback signal after the conversion circuit 24 and the swing motor 10 are electrically connected to the internal main chip 22, and the internal main chip 22 performs matching judgment on the feedback signal and the sent control signal. It should be noted that the signal fed back by the operation angle of the wind oscillating motor 10 may affect the driving signal of the conversion circuit 24, so that the inner main chip 22 may determine whether the operation angle of the wind oscillating motor 10 is normal according to the received feedback signal, so that the inner main chip 22 adjusts the control signal to enable the wind oscillating motor 10 to operate normally.

103. When the inner machine main chip determines that the feedback signal is abnormal, the inner machine main chip controls the wind swing motor to stop and outputs an alarm signal.

The feedback signal may be understood as a pulse width modulation signal, and when the feedback signal detected by the internal main chip 22 does not match the sent control signal, for example, the duty ratio of the feedback signal is different from the duty ratio of the driving signal sent according to the control signal or is not within a preset range, it may be determined that the feedback signal is abnormal. After the feedback signal is determined to be abnormal, the internal main chip 22 can change the driving signal into a continuous low level through the conversion circuit 24 so as to disconnect the operation of the wind swing motor 10, and simultaneously output an alarm signal to a user to remind the user that the wind swing motor 10 is abnormal, so that the larger damage can be avoided, and the subsequent maintenance is also facilitated.

104. When the inner machine main chip determines that the feedback signal is normal, the inner machine main chip controls the wind swing motor to operate within a first angle range.

When the feedback signal detected by the inner main chip 22 matches the sent control signal, for example, the duty ratio of the feedback signal is approximately the same as the duty ratio of the driving signal sent according to the control signal or within a preset range, it may be determined that the feedback signal is normal, that is, the operation of the swing wind motor 10 is normal, at this time, the working mode of the swing wind motor 10 may be obtained, and when the swing wind motor 10 is in the first working mode, that is, the ordinary operating mode, the inner main chip 22 controls the swing wind motor 10 to operate within the first angle range. It should be noted that, when the yaw motor 10 is controlled to start up and operate, the operation angle of the yaw motor 10 may be understood as an angle within the first angle range. When the pwm signal fed back from the detection circuit 24 is normal, the wind turbine 10 is controlled to operate normally, that is, to continue to operate within the first angle range according to the original operation.

By arranging the detection circuit 26 capable of detecting the operation state of the swing motor 10, the inner main chip 22 can monitor the operation state of the swing motor 10 in real time according to the feedback signal transmitted by the detection circuit 26.

It should be noted that the control method of the yaw motor is not limited thereto, for example, please refer to fig. 7, and fig. 7 is another schematic flow chart of the control method of the yaw motor according to the embodiment of the present application. The control method of the swing wind motor is applied to the control device of the swing wind motor, and the control device of the swing wind motor can refer to the control device shown in the figures 1-5. The control method of the swing wind motor comprises the following steps:

201. the inner machine main chip controls the operation of the wind swing motor through a conversion circuit.

202. And the inner machine main chip determines whether a feedback signal after the conversion circuit is electrically connected with the wind swing motor is abnormal.

203. When the inner machine main chip determines that the feedback signal is abnormal, the inner machine main chip controls the wind swing motor to stop and outputs an alarm signal.

Regarding 201 to 203: reference may be made to the description of steps 101-103, respectively.

204. When the inner machine main chip determines that the feedback signal is within the first preset range, the inner machine main chip determines that the feedback signal is normal and obtains the working mode of the swing motor.

205. When the wind swinging motor is in a first working mode, the inner machine main chip controls the wind swinging motor to operate in a first angle range.

206. When the swing motor is in a second working mode, the internal machine main chip determines whether the feedback signal is in a second preset range, and the second preset range is in the first preset range and is smaller than the first preset range; if the feedback signal exceeds a second preset range, the inner machine main chip adjusts the control signal and sends out a driving signal to enable the wind swinging motor to operate in a second angle range, and the second angle range is within the first angle range and smaller than the first angle range.

With respect to 204-206, it may be determined that the feedback signal is normal, i.e., the operation of the swing wind motor 10 is normal, for example, when the duty ratio of the feedback signal matches the duty ratio of the driving signal converted according to the control signal, i.e., the feedback signal is within the first preset range. At this time, the working mode of the wind swing motor 10 may be obtained, and when the wind swing motor is in the first working mode, the wind swing motor 10 is controlled to operate within the first angle range. The first mode of operation can be understood as a normal mode of operation, i.e. without special requirements of the user. When the swing motor 10 is in the second operating mode, the internal main chip 22 determines whether the feedback signal is within a second preset range. The second mode of operation may be understood as the mode of operation when the user has a particular need. When the feedback signal exceeds a second preset range, the internal main chip 22 adjusts the driving signal and outputs the adjusted driving signal to the swing motor 10 so that the swing motor 10 operates within the second angle range. The second preset range is within the first preset range and smaller than the first preset range, and the second angle range is within the first angle range and smaller than the first angle range. It should be noted that the endpoint value of the second preset range is within the first preset range, and the second preset range is smaller than the first preset range. The endpoint value of the second angular range is also within the first angular range, and the second angular range is less than the first angular range. It should be noted that, the feedback signal fed back by the detection circuit 26 provided in the embodiment of the present application may first determine whether the operation of the swing wind motor 10 is normal according to the feedback signal, and then determine whether the operation of the swing wind motor 10 meets the use requirement of the user after determining that the operation of the swing wind motor 10 is normal, and when the feedback signal is within the first preset range but not within the second preset range, it may be determined that the operation of the swing wind motor 10 is normal and meets the use requirement of the user, and at this time, the inner machine main chip 22 controls the swing wind motor 10 to operate within the second angle range. When the feedback signal is within the second preset range, it can be determined that the operation of the wind oscillating motor 10 is normal but not in accordance with the use requirement of the user, and at this time, the inner machine main chip 22 controls the wind oscillating motor 10 to operate within the second angle range so as to meet the use requirement of the user. The second angle range may be a second angle range corresponding to different modes pre-stored in the internal main chip 22, or may be a second angle range input to the internal main chip 22 according to a swing angle required by a user. The driving signal is a pulse width modulation signal, and the inner main chip 22 adjusts a duty ratio of the pulse width modulation signal and outputs the adjusted pulse width modulation signal to the wind-swinging motor 10 so that the wind-swinging motor 10 operates in a second angle range. It will be appreciated that the duty cycle of the pwm signal is modulated to cause the swing wind motor 10 to operate at a desired operating angle.

The control device 20 of the wind-swinging motor with the detection circuit 26 provided by the embodiment of the application enables the inner main chip 22 of the indoor variable-frequency air conditioning equipment 1 to detect the actual output angle of the wind-swinging motor 10. When the swing motor 10 or the control circuit is abnormal, the internal machine main chip 22 can output an alarm in time to stop the air conditioner, so that the abnormality caused by the operation of the fan in the air conditioner under the condition that the swing motor 10 is not started is avoided, and the reliability of the air conditioner 1 is improved. Meanwhile, when the operating angle of the wind swing motor 10 deviates, the PWM output duty ratio can be adjusted, the operating angle of the wind swing motor 10 can be effectively corrected, and the user experience of the air conditioning equipment 1 can be improved.
