Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. 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 invention.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
The invention provides a discharging method of an air conditioner. The method is mainly applicable to an air conditioner having an ac motor, for example, an air conditioner having a PG motor.
Fig. 1 is a schematic method diagram of an embodiment of a discharging method of an air conditioner according to the present invention.
As shown in fig. 1, according to an embodiment of the present invention, the discharging method includes at least step S110, step S120, and step S130.
Step S110, determining whether the zero-crossing detection circuit of the air conditioner has not detected a zero-crossing signal for a first preset time.
And step S120, when judging that no zero-crossing signal is detected in the continuous first preset time, judging whether the target rotating speed of the indoor fan of the air conditioner is zero or not.
When the air conditioner is powered off in normal operation, residual voltage energy is mainly concentrated in an X capacitor of a strong electromagnetic interference (EMI) filter element and then is released through a loop resistor due to the forward conduction characteristic of a rectifier bridge. Whether the air conditioner is electrified or not can be quickly identified through the zero-crossing detection circuit. When the air conditioner is electrified, because the zero-live wire is a sine wave characteristic, each fixed period has a zero crossing point to generate a zero crossing signal; when the air conditioner is powered off, the sine wave of the zero-live wire disappears, and the zero-crossing signal also disappears, so that whether the air conditioner is in a power-on state or not can be judged by detecting the zero-crossing signal, and effective and rapid discharging is realized.
Specifically, whether the air conditioner is in a start-up state or a shut-down state, whether a zero-crossing signal is detected or not is judged, and if the zero-crossing signal is not detected within a first preset time, whether the target rotating speed of an indoor fan of the air conditioner is zero or not is judged. For example, a zero-crossing detection circuit is arranged on a mainboard of an air conditioner internal unit, so that a zero-crossing signal can be effectively detected.
And step S130, if the target rotating speed of the indoor fan of the air conditioner is judged to be zero, controlling the motor of the indoor fan to operate according to the set maximum rotating speed so as to realize discharging by using the redundant electric quantity consumed by the coil in the motor.
Specifically, if no zero-crossing signal is detected for the first preset time T1, and it is determined that the target rotation speed of the indoor fan of the air conditioner is zero, the ac motor is controlled to output at full speed, that is, the ac motor operates at the set maximum rotation speed, when the motor outputs at full speed, the coil inside the motor may be used for discharging, the coil body itself has impedance, and when there is power, the excess power may be consumed by the coil, thereby achieving discharging.
Preferably, the first preset time is greater than a detection interval time for detecting the zero-crossing signal.
That is, the first preset time T1 needs to be longer than the time (i.e., the detection interval time) at which the detected zero-crossing signal can be fixed each time: because if the time of the zero-crossing signal is less than the time that can be fixed every time, the zero-crossing signal is not reached, and the zero-crossing signal is not reached in case of air conditioner outage, the detection error can be caused.
Preferably, the first preset time is less than the time when the air conditioner main chip does not work.
When the detection time of the zero-crossing signal is too long, the air conditioner main chip may not work, and the effect of quick discharge cannot be achieved at the moment.
Further, when the motor of the indoor fan is controlled to operate according to the set maximum rotating speed, if the zero-crossing signal is detected again, the motor is controlled to operate according to a normal control mode, so that the indoor fan of the air conditioner operates according to the set wind speed.
Specifically, if the zero-crossing signal is detected again when the motor is outputting at full speed, it indicates that the air conditioner is powered on again at this time, and in order to avoid the influence on the actual use, it is necessary to stop the motor from outputting at full speed, and control the motor to switch to the control mode when the air conditioner normally operates, and execute the control according to the set wind speed (for example, the wind speed of the windshield set by the user).
Fig. 2 is a method schematic diagram of another embodiment of a discharging method of an air conditioner provided by the present invention.
As shown in fig. 2, according to another embodiment of the present invention, the discharging method further includes step S140.
And step S140, controlling the motor of the indoor fan to stop running according to the set maximum rotating speed after controlling the motor to run according to the set maximum rotating speed for a second preset time.
And when the motor outputs full speed for a second preset time T2, stopping the output of the motor, so that the residual voltage at two ends of the plug can be quickly released to be below the safe voltage.
In order to clearly illustrate the technical solution of the present invention, the following describes an execution flow of the discharging method of the air conditioner according to an embodiment of the present invention.
Fig. 3 is a schematic method diagram of an embodiment of a discharging method of an air conditioner according to the present invention.
As shown in fig. 3, no matter the air conditioner is in the on state or the off state, when the zero-crossing signal is not detected for the continuous time T1 and the target rotation speed of the fan in the air conditioner is 0, the ac motor is controlled to output at full speed, the residual voltage at the two ends of the plug can be quickly released below the safety voltage by using the coil in the motor to consume the redundant electric quantity to realize discharging. When the motor outputs at full speed, if the zero-crossing signal is detected again, the air conditioner is powered on again at this time, and in order to avoid influence on actual use of a user, the motor needs to be stopped from outputting at full speed, and the motor is controlled to be in a control mode when the air conditioner operates normally and is executed according to the rotating speed of a windshield required to operate by the user.
The invention also provides a discharging device of the air conditioner. The device is mainly applicable to an air conditioner having an ac motor, for example, an air conditioner having a PG motor.
Fig. 4 is a block diagram of an embodiment of a discharging device of an air conditioner according to the present invention. As shown in fig. 4, the discharge apparatus 100 includes a first judgment unit 110, a second judgment unit 120, and a control unit 130.
The first judging unit 110 is configured to judge whether a zero-crossing signal is not detected by a zero-crossing detection circuit of a motor of an indoor fan of the air conditioner for a first preset time. A second judging unit 120, configured to judge whether a target rotation speed of an indoor fan of the air conditioner is zero when the first judging unit 110 judges that no zero-crossing signal is detected for a first preset time.
When the air conditioner is powered off in normal operation, residual voltage energy is mainly concentrated in an X capacitor of a strong-current EMI filter element due to the forward conduction characteristic of a rectifier bridge and then is released through a loop resistor. Whether the air conditioner is electrified or not can be quickly identified through a zero-crossing detection circuit of a motor (such as a PG motor) of the indoor fan. When the air conditioner is electrified, because the zero-live line is a sine wave characteristic, each fixed period has a zero crossing point to generate a zero crossing signal; when the air conditioner is powered off, the sine wave of the zero-live wire disappears, and the zero-crossing signal also disappears, so that whether the air conditioner is in a power-on state or not can be judged by detecting the zero-crossing signal, and effective and rapid discharging is further realized.
Specifically, whether the air conditioner is in the on state or the off state, the first determining unit 110 determines whether the zero-crossing signal is detected, and if the first determining unit 110 determines that the zero-crossing signal is not detected for the first preset time, the second determining unit 120 determines whether the target rotation speed of the indoor fan of the air conditioner is zero. For example, a zero-crossing detection circuit is arranged on a mainboard of an air conditioner internal unit, so that a zero-crossing signal can be effectively detected.
A control unit 130, configured to control a motor of the indoor fan to operate at a set maximum rotation speed if the second determination unit 120 determines that the target rotation speed of the indoor fan of the air conditioner is zero, so as to implement discharging by using excess electric quantity consumed by a coil inside the motor.
Specifically, if no zero-crossing signal is detected for the first preset time T1, and it is determined that the target rotation speed of the indoor fan of the air conditioner is zero, the ac motor is controlled to output at full speed, that is, the ac motor operates at the set maximum rotation speed, when the motor outputs at full speed, the coil inside the motor may be used for discharging, the coil body itself has impedance, and when there is power, the excess power may be consumed by the coil, thereby achieving discharging.
Preferably, the first preset time is greater than a detection interval time for detecting the zero-crossing signal. That is, the first preset time T1 needs to be longer than the time (i.e., the detection interval time) at which the detected zero-crossing signal can be fixed each time: because if the time of the zero-crossing signal detected is less than each time, the zero-crossing signal may not be obtained, and the zero-crossing signal is not obtained when the air conditioner is powered off, the detection error can be caused.
Preferably, the first preset time is less than the time when the air conditioner main chip does not work.
When the detection time of the zero-crossing signal is too long, the main chip may not work, and the effect of quick discharge cannot be achieved at the moment.
Further, the control unit 130 is further configured to: and when the motor of the indoor fan is controlled to operate according to the set maximum rotating speed, if the zero-crossing signal is detected again, the motor is controlled to operate according to a normal control mode, so that the indoor fan of the air conditioner operates according to the set wind speed.
Specifically, if the zero-crossing signal is detected again when the motor is outputting at full speed, it indicates that the air conditioner is powered on again at this time, and in order to avoid an influence on actual use, the motor needs to be stopped from outputting at full speed, and the motor is controlled to be switched to a control mode when the air conditioner is normally operating, and the control mode is executed according to a set wind speed (for example, a windshield set by a user) rotating speed.
According to another embodiment of the present invention, the control unit 130 is further configured to: and after controlling the motor of the indoor fan to operate at the set maximum rotating speed for a second preset time, controlling the motor to stop operating at the set maximum rotating speed.
And when the motor outputs full speed for a second preset time T2, stopping the output of the motor, so that the residual voltage at two ends of the plug can be quickly released to be below the safe voltage.
The present invention also provides a storage medium corresponding to the discharging method of the air conditioner, on which a computer program is stored, which when executed by a processor implements the steps of any of the aforementioned methods.
