[0051] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to enable the scope of the present invention to be fully communicated to those skilled in the art.

[0052] The air supply mode (also called blowing mode) of the air conditioner is one of the necessary functions of the air conditioner. Among them, the air supply mode is mainly divided into two states, one is the air supply mode under sweeping wind, and the other is the air supply mode under static state.

[0053] Under normal conditions, the inverter air conditioner only needs to adjust the speed by the speed difference between the target speed and the current feedback speed. However, when the inverter air conditioner is turned on the air sweeping mode, the air sweeping plate affects the air duct resistance when it rotates to different positions, thus forming different loads that affect the driving characteristics of the motor and easily cause abnormal noise of the air conditioner.

[0054] Based on the above technical problems, an embodiment of the present invention is proposed. The embodiment of the present invention may include first responding to a purge start instruction to detect the operating speed of the blower motor. Then, when the operating speed of the blower motor reaches a stable state, the purge motor is started, and the air guide plate is controlled to operate at a first purge speed. Then, the speed fluctuation of the blower motor at the first purge speed is monitored. Finally, according to the speed fluctuation, the purge speed of the air guide plate is adjusted to ensure that the operating speed of the blower motor remains stable. Therefore, the control of the purge speed of the air guide plate can be introduced according to the speed fluctuation of the blower motor. Thereby, the problems such as excessive change in air duct resistance and abnormal noise caused by large wind speed fluctuation in the purge mode can be avoided, the operating noise of the air conditioner can be further reduced, and the user experience can be improved.

[0055] Reference Figure 1 , shows a control method of an air conditioner provided by an embodiment of the present invention, the method may include:

[0056] S101, in response to a blow air start instruction, detecting the operating speed of the blower motor.

[0057] In the embodiment of the present invention, referring to Figure 2As shown, an air conditioner is shown, and the air conditioner may include a blowing motor 201, an air guide plate, a sweeping motor 202 for controlling the rotation of the air guide plate, and a controller 203. The blowing motor 201 and the sweeping motor 202 are electrically connected to the controller 203 respectively. The control method is applied to the controller 203.

[0058] The wind sweeping start instruction is generated based on the triggering of the editing operation of the wind sweeping control on the user terminal, or the wind sweeping start instruction is generated based on the triggering of the touch operation of the wind sweeping button on the remote control. The wind sweeping start instruction is used to start the wind sweeping motor 202, so that the air guide plate can be driven by the wind sweeping motor 202 to rotate, thereby starting the up and down wind sweeping mode of the air conditioner. The air guide plate can be rotatably connected to the air outlet of the air duct of the air conditioner, and the rotating shaft is coaxially fixed with the output shaft of the wind sweeping motor 202, so that the wind guide plate can be driven to rotate by the wind sweeping motor 202 to adjust the up and down blowing angles of the air conditioner.

[0059] The blower motor 201 is a driving component of the fan assembly, and the airflow generated during operation is blown out through the air duct. After obtaining the wind sweeping start instruction, the controller 203 can pre-detect the operating speed of the blower motor 201 and determine whether the operating speed of the blower motor 201 reaches a stable state.

[0060] In the case where the speed fluctuation amplitude of the blower motor 201 is large, for example, when the speed fluctuation amplitude exceeds (is greater than) the preset fluctuation threshold, starting the sweeping motor 202 is likely to generate different air duct resistances, affecting the driving characteristics of the blower motor 201, and may increase the instability of the blower motor 201 during the speed adjustment process, thereby possibly generating abnormal noise. For example, the speed of the blower motor 201 is not matched, or the wind speed fluctuates during speed adjustment, and the abnormal noise is similar to the "sound of waves" or "wheezing", thereby affecting the comfort of the air conditioner.

[0061] S102: When the operating speed of the blowing motor reaches a stable state, start the sweeping motor and control the air guide plate to operate at a first sweeping speed.

[0062] In an embodiment of the present invention, when the speed fluctuation amplitude of the blower motor 201 is small, for example, when the speed fluctuation amplitude is less than the preset fluctuation threshold, it can be determined that the operating speed of the blower motor 201 has reached a stable state. At this time, the sweeping motor 202 is started, and the air guide plate is controlled to operate at a first sweeping speed. The sweeping speed can be understood as the time required for the air guide plate to rotate at a preset angle interval. The first sweeping speed can be understood as a sweeping method with a moderate speed, so that when the air guide plate operates at the first sweeping speed, the user can quickly feel the change in the blowing angle.

[0063] S103, monitoring the rotation speed fluctuation of the blower motor at the first sweeping speed.

[0064] In the embodiment of the present invention, when the air guide plate is running at the first air sweeping speed, the controller 203 may also monitor the speed fluctuation of the blower motor 201. For example, the speed fluctuation of the blower motor 201 may be monitored when the air guide plate rotates at least one complete cycle. If the speed fluctuation amplitude of the blower motor 201 is small, it can be determined that the change in air duct resistance caused by the rotation of the air guide plate has little effect on the driving characteristics of the blower motor 201, and the blower motor 201 runs stably without generating abnormal noise.

[0065] If the rotation speed fluctuation of the blower motor 201 is large, it can be determined that the change in air duct resistance caused by the rotation of the air guide plate has a great impact on the driving characteristics of the blower motor 201 and is likely to generate abnormal noise.

[0066] S104. According to the speed fluctuation, the air sweeping rate of the air guide plate is adjusted to ensure that the operating speed of the blower motor remains stable.

[0067] In an embodiment of the present invention, when the speed fluctuation amplitude of the blower motor 201 is small, it is determined that the operating speed of the blower motor remains stable, and the sweeping speed of the sweeping motor 202 is recorded, for example, the first sweeping speed is recorded, so that after responding to the sweeping start instruction, the sweeping motor 202 can keep running at the first sweeping speed.

[0068] In the case where the speed fluctuation amplitude of the blower motor 201 is large, it is determined that the operating speed of the blower motor has not reached a stable state, and the sweeping speed of the sweeping motor 202 is adjusted. For example, the sweeping speed can be reduced on the basis of the first sweeping speed. And when the operating speed of the blower motor 201 remains stable, the corresponding sweeping speed of the air guide plate is determined as the operating sweeping speed of the air guide plate. In this way, the control of the sweeping speed of the air guide plate can be introduced according to the speed fluctuation of the blower motor 201. Thereby, problems such as excessive changes in air duct resistance in the sweeping mode and abnormal noise caused by large wind speed fluctuations can be avoided, and the operating noise of the air conditioner can be further reduced, thereby improving the user experience.

[0069] Reference Figure 3 , shows another method for controlling an air conditioner provided by an embodiment of the present invention, the method may include:

[0070] S301. In response to a wind sweep start instruction, obtain a current start time period.

[0071] In an embodiment of the present invention, the wind sweeping start instruction is used to start the wind sweeping motor 202, so that the wind guide plate can be driven by the wind sweeping motor 202 to rotate, thereby starting the up and down wind sweeping mode of the air conditioner. After obtaining the wind sweeping start instruction, the controller 203 can pre-query the current start time period. In some embodiments, the start time period can be divided into two types according to the control mode: a set night time period and a set day time period. For example, the set night time period can be the time period from 9 pm to 8 am, and correspondingly, the set day time period can be the time period from 8 am to 9 pm.

[0072] S302: Determine whether the current startup time period belongs to the set night time period.

[0073] In the embodiment of the present invention, if the current startup period belongs to the set nighttime period, it is considered that the user may enter a sleeping state or a resting state. Thus, the following step S309 is executed to control the air guide plate to operate at the slowest wind sweeping speed. At this wind sweeping speed, the driving characteristics of the blower motor 201 are minimally affected, thereby ensuring the stability of the speed regulation of the blower motor 201. If the current startup period does not belong to the set nighttime period, it can be determined that the current startup period is a set daytime period, and the following step S303 is executed.

[0074] S303, detecting the operating speed of the blower motor to determine whether the operating speed of the blower motor reaches a stable state.

[0075] In the embodiment of the present invention, when the current startup period belongs to the set daytime period, the controller 203 detects the running speed of the blower motor 201 and determines whether the running speed of the blower motor 201 reaches a stable state.

[0076] In the case where the speed fluctuation amplitude of the blower motor 201 is large, for example, when the speed fluctuation amplitude exceeds (is greater than) the preset fluctuation threshold, the blower motor 201 may be in the motor starting stage or the motor speed adjustment stage. Among them, the motor starting stage is mainly to quickly increase the speed, and the motor speed adjustment stage is mainly to quickly reach the target speed. In any of the above two stages, starting the wind sweeping motor 202 is likely to produce different air duct resistances, affecting the driving characteristics of the blower motor 201, and may increase the instability of the blower motor 201 during the speed adjustment process, thereby possibly generating abnormal noise. For example, the speed of the blower motor 201 is not matched, or the wind speed fluctuates during the speed adjustment, and the abnormal noise is similar to the "sound of waves" or "panting", thereby affecting the comfort of the air conditioner.

[0077] Thus, when the speed fluctuation amplitude of the blower motor 201 is small, it is determined that the running speed of the blower motor 201 has reached a stable state, and it can be determined that the blower motor 201 has entered a stable operation stage. The preset fluctuation threshold can be 1 revolution per minute. For example, if the speed difference between the number of revolutions of the blower motor 201 in the previous minute and the number of revolutions in the current minute is within 10 revolutions (including 10 revolutions), it is determined that the running speed of the blower motor 201 has reached a stable state.

[0078] In the stable operation stage, the operating speed of the blower motor 201 is mainly subject to stable regulation. At this time, when the air guide plate rotates to different positions, different loads will be generated on the operation of the blower motor 201, thereby affecting the driving characteristics of the blower motor 201. Therefore, the following step S304 can be executed, and the wind sweeping rate of the air guide plate is controlled so that in the stable operation stage, the air guide plate will not affect the operating stability of the blower motor 201 in the wind sweeping mode, thereby ensuring that no abnormal noise is generated. In the case where it is determined that the operating speed of the blower motor 201 has not reached a stable state, starting the wind sweeping motor 202 is likely to cause abnormal noise, so that step S303 is repeated, and when the blower motor 201 enters the stable operation stage, the wind sweeping motor 202 is started again.

[0079] In some other optional embodiments, after responding to the wind sweeping start instruction, the controller 203 may also first detect the running speed of the blower motor 201 to determine whether the running speed of the blower motor 201 has reached a stable state. After the running speed of the blower motor 201 has reached a stable state, the current start-up period is obtained. If the current start-up period belongs to the set night time period, the following step S309 is executed. If the current start-up period belongs to the set daytime period, the following step S304 is executed. Those skilled in the art can adjust the order of the above execution steps according to actual design requirements, and no excessive restrictions are made here.

[0080] S304, starting the wind sweeping motor, and controlling the wind guide plate to operate at a first wind sweeping speed.

[0081] In the embodiment of the present invention, the wind sweeping motor 202 is started, and the wind guide plate is controlled to operate at a first wind sweeping speed. The wind sweeping speed can be understood as the time required for the wind guide plate to rotate at a preset angle interval. Multiple wind sweeping speeds can be pre-set for the wind guide plate. For example, the wind sweeping speed can include a first wind sweeping speed, a second wind sweeping speed, a third wind sweeping speed, and a fourth wind sweeping speed, etc.

[0082] The first air sweeping rate can be understood as a moderate air sweeping mode. For example, the first air sweeping rate can be less than the fourth air sweeping rate, and the first air sweeping rate is greater than the second air sweeping rate, and greater than the third air sweeping rate. When the air guide plate operates at the first air sweeping rate, the user can quickly feel the change in the blowing angle.

[0083] In some embodiments, the preset angle interval may be determined based on the control logic of the wind sweeping motor 202. For example, the preset angle interval may be 1°, 2°, and 3°, etc. Those skilled in the art may determine the specific preset angle interval based on actual design requirements. For example, the first wind sweeping rate may be 1° rotation per 20ms (milliseconds), the second wind sweeping rate may be 1° rotation per 30ms (milliseconds), the second wind sweeping rate may be 1° rotation per 50ms (milliseconds), the fourth wind sweeping rate may be 1° rotation per 4ms (milliseconds), etc. Those skilled in the art may determine the specific wind sweeping rate based on actual design requirements or test results, and no further limitation is made here.

[0084] S305: monitor whether the operating speed of the blower motor at the first sweeping speed reaches a stable state.

[0085] In the embodiment of the present invention, when the air guide plate is running at the first wind sweeping rate, the controller 203 can also monitor the speed fluctuation of the blower motor 201. For example, the speed fluctuation of the blower motor 201 can be monitored when the air guide plate rotates at least one complete cycle (i.e., sweeping up and down from the top to the bottom). If the speed fluctuation amplitude of the blower motor 201 is small, it can be determined that the change in air duct resistance caused by the rotation of the air guide plate has little effect on the driving characteristics of the blower motor 201, and the blower motor 201 runs stably without generating abnormal noise. Therefore, when it is determined that the running speed of the blower motor 201 reaches a stable state, the following step S310 is executed.

[0086] If the speed fluctuation amplitude of the blower motor 201 is large (the speed fluctuation amplitude is greater than the preset fluctuation threshold), it can be determined that the change in air duct resistance caused by the rotation of the air guide plate has a great impact on the driving characteristics of the blower motor 201 and is prone to abnormal noise. At this time, it is necessary to consider controlling the wind sweeping rate of the air guide plate. Therefore, when it is determined that the operating speed of the blower motor 201 has not reached a stable state, the following step S306 is executed.

[0087] S306: Divide the wind sweeping area associated with the wind guide plate to obtain a plurality of wind sweeping intervals.

[0088] In an embodiment of the present invention, the wind sweeping area can be the wind sweeping angle range of the wind guide plate for sweeping up and down. For example, when the wind guide plate is in the initial position (for example, the topmost position for sweeping up and down), the corresponding wind sweeping angle range is 0-100 degrees.

[0089] The wind sweeping area associated with the wind guide plate is divided, preferably according to a preset angle interval, so that the angle values ​​corresponding to the multiple wind sweeping intervals after the division are evenly distributed. In some embodiments, considering that the wind guide plate needs to change direction when running to the two sides of the wind sweeping area, when dividing the wind sweeping area, the angle interval corresponding to the wind sweeping intervals on both sides is less than or equal to half of the preset angle interval.

[0090] For example, the area on both sides can be considered as a wind sweeping interval in advance. When the wind sweeping angle range is 0-100 degrees, the corresponding preset angle interval can be set to 10 degrees, so as to be evenly divided into 10 wind sweeping intervals, each wind sweeping interval is 10 degrees, and the angle interval of the wind sweeping intervals on both sides can be 5 degrees, and the angle intervals corresponding to the other wind sweeping intervals can all be 10 degrees, and finally 11 wind sweeping intervals are obtained.

[0091] Those skilled in the art may also divide the air sweeping area into other numbers according to the actual air sweeping area, and no further limitation is made here.

[0092] S307 , determining a target wind sweeping interval in which the rotation speed fluctuation amplitude exceeds a preset fluctuation threshold from the multiple wind sweeping intervals.

[0093] In the embodiment of the present invention, after determining multiple wind sweeping intervals, the controller 203 can also detect the speed fluctuation of the blower motor 201 at the first wind sweeping rate, and specifically detects the speed fluctuation amplitude of the blower motor 201, and which wind sweeping intervals the air guide plate enters will become larger (greater than a preset fluctuation threshold). Therefore, after at least one round of detection of the upper and lower wind sweeping cycles, the wind sweeping interval in which the speed fluctuation amplitude exceeds the preset fluctuation threshold can be determined from the multiple wind sweeping intervals and used as the target wind sweeping interval, thereby obtaining at least one target wind sweeping interval.

[0094] After the blower motor 201 enters the stable operation stage, when the air guide plate sweeps air at the first operating rate, the driving characteristics of the blower motor 201 will change significantly when the air guide plate enters the target sweeping range, thereby increasing the uncertainty of the blower motor 201 during the stable speed adjustment process and easily generating abnormal noise.

[0095] S308. When the air guide plate is located in the target air sweeping interval, reduce the air sweeping rate of the air guide plate to keep the operating speed of the blower motor stable.

[0096] In the embodiment of the present invention, in order to avoid abnormal noise, it is necessary to adjust the air sweeping rate of the air guide plate when the air guide plate enters the target air sweeping interval. For example, the air sweeping rate of the air guide plate can be reduced, so that the air guide plate can sweep up and down more slowly, so that the air duct resistance changes slowly, thereby reducing the impact on the driving characteristics of the blower motor 201. After reducing the air sweeping rate of the air guide plate, continue to monitor the speed fluctuation of the blower motor 201. If the speed fluctuation amplitude of the blower motor 201 is still small when the air guide plate enters the target air sweeping interval, for example, when the speed fluctuation amplitude is less than the preset fluctuation threshold, it can be determined that the operating speed of the blower motor 201201 reaches a stable state. Therefore, it can be determined that the air guide plate operates at the reduced air sweeping rate in the target air sweeping interval, which will not affect the driving characteristics of the blower motor 201 and can ensure that no abnormal noise is generated.

[0097] In some embodiments, the air sweeping rate of the air guide plate can be reduced to a second air sweeping rate, wherein the second air sweeping rate is less than the first air sweeping rate. If the operating speed of the blower motor 201 does not exceed the preset fluctuation threshold, it is determined that when the air guide plate enters the target air sweeping interval according to the second air sweeping rate, the operating speed of the blower motor 201 reaches a stable state. Thus, it can be determined that the air guide plate operates at the second air sweeping rate in the target air sweeping interval, which will not affect the driving characteristics of the blower motor 201 and can ensure that no abnormal noise is generated. Thus, a wind sweeping control record of the air guide plate can be formed. For example, when the air guide plate enters the target air sweeping interval, it operates at the second air sweeping rate; when the air guide plate enters other air sweeping intervals except the target air sweeping interval, it operates at the first air sweeping rate. Thus, the operating speed of the blower motor 201 can be guaranteed to be stable, and the air conditioner will not generate abnormal noise, thereby improving the user experience.

[0098] In other embodiments, the air sweeping rate of the air guide plate can be reduced to a second air sweeping rate, wherein the second air sweeping rate is less than the first air sweeping rate. If the operating speed of the blower motor 201 still exceeds the preset fluctuation threshold, it is determined that when the air guide plate enters the target air sweeping interval at the second air sweeping rate, the operating speed of the blower motor 201 has not yet reached a stable state. The driving characteristics of the blower motor 201 will still change significantly when the air guide plate enters the target air sweeping interval, thereby increasing the uncertainty of the blower motor 201 in the process of speed stabilization adjustment, and easily generating abnormal noise.

[0099] The air sweeping rate of the air guide plate can be further reduced to a third air sweeping rate. The third air sweeping rate can be the slowest air sweeping rate that is preset, and the third air sweeping rate is less than the second air sweeping rate. Thus, it can be ensured that when the air guide plate enters the target air sweeping interval, the operating speed of the blower motor 201 reaches a stable state. It can be determined that the air guide plate operates at the third air sweeping rate in the target air sweeping interval, which will not affect the driving characteristics of the blower motor 201 and can ensure that no abnormal noise is generated. Thus, a wind sweeping control record of the air guide plate can be formed. For example, when the air guide plate enters the target air sweeping interval, it operates at the third air sweeping rate; when the air guide plate enters other air sweeping intervals except the target air sweeping interval, it operates at the first air sweeping rate. Thus, it can be ensured that the operating speed of the blower motor 201 is stable, and the air conditioner will not generate abnormal noise, thereby improving the user experience.

[0100] In some embodiments, the second sweep air rate may be the sum of half of the difference between the first sweep air rate and the third sweep air rate and the third sweep air rate. Thus, the second sweep air rate may be an intermediate value between the first sweep air rate and the third sweep air rate, thereby facilitating the speed reduction adjustment of the sweep air rate of the air guide plate.

[0101] S309, controlling the air guide plate to operate at a third air sweeping rate.

[0102] In the embodiment of the present invention, when the current startup period belongs to the set night time period, it is considered that the user may enter a sleeping state or a resting state. Thus, the following step S309 is executed to control the air guide plate to operate at the slowest air sweeping rate, that is, the third air sweeping rate. When the air guide plate operates at the third air sweeping rate, the driving characteristics of the blower motor 201 are minimally affected, thereby ensuring the stability of the speed adjustment of the blower motor 201 and ensuring that no abnormal noise is generated, thereby improving the user's comfort during the set night time period.

[0103] S310, controlling the air guide plate to operate at the first air sweeping rate.

[0104] In an embodiment of the present invention, when the air guide plate can be monitored to rotate for at least one complete cycle (i.e., sweeping air up and down from the top to the bottom), and the fluctuation amplitude of the rotation speed of the blower motor 201 remains small, it can be determined that the change in air duct resistance generated when the air guide plate operates at the first sweeping speed has little effect on the driving characteristics of the blower motor 201, and the blower motor 201 operates stably without generating abnormal noise, thereby forming a sweeping control record of the air guide plate. For example, when the air guide plate operates at the first sweeping speed, it can ensure that the operating speed of the blower motor 201 is stable, and the air conditioner does not generate abnormal noise, thereby improving the user experience.

[0105] In an optional embodiment of the invention, the method may further include:

[0106] When the wind speed adjustment instruction associated with the blowing motor 201 is obtained, the operation of the air guide plate is stopped.

[0107] When the operating speed of the blowing motor 201 reaches a stable state, the sweeping motor 202 is started, and the air guide plate is controlled to operate at a first sweeping speed.

[0108] In the embodiment of the present invention, considering that during the operation or startup of the air conditioner, the user may set different windshields, or when the system needs to adjust the wind speed of the blower motor 201, the controller 203 will receive the corresponding wind speed adjustment instruction, or generate the corresponding wind speed adjustment instruction. Thus, after responding to the wind speed adjustment instruction, the operation of the air guide plate is stopped, that is, the rotation of the wind sweeping motor 202 is stopped, so that the blower motor 201 will not produce instability and abnormal noise due to the influence of the wind sweeping speed of the air guide plate during the rapid speed adjustment process, and when the running speed of the blower motor 201 reaches a stable state, that is, when the blower motor 201 enters a new speed stabilization stage, the wind sweeping motor 202 is restarted and runs at the first wind sweeping speed. And the speed fluctuation of the blower motor 201 at the first wind sweeping speed can continue to be monitored. According to the wind sweeping speed adjustment method in each of the embodiments of the invention described above, the wind sweeping speed of the air guide plate is adjusted to ensure that the running speed of the blower motor 201 remains stable.

[0109] In some optional embodiments, in response to the wind sweeping start instruction, the controller 203 can also drive the wind sweeping motor 202 to work after starting the wind sweeping motor 202, and drive the air guide plate to reset to the set initial position, wherein technical personnel in this field can determine the specific set initial position of the air guide plate according to actual design requirements, and no excessive restrictions are made here.

[0110] In summary, an embodiment of the present invention discloses a control method for an air conditioner, which may include first responding to a purge start instruction and detecting the operating speed of the blower motor 201. Then, when the operating speed of the blower motor 201 reaches a stable state, the purge motor 202 is started, and the air guide plate is controlled to operate at a first purge speed. Then, the speed fluctuation of the blower motor 201 at the first purge speed is monitored. Finally, according to the speed fluctuation, the purge speed of the air guide plate is adjusted to ensure that the operating speed of the blower motor 201 remains stable. Therefore, the control of the purge speed of the air guide plate can be introduced according to the speed fluctuation of the blower motor 201. Thereby, the problems such as excessive change in air duct resistance and abnormal noise caused by large wind speed fluctuation in the purge mode can be avoided, and the operating noise of the air conditioner can be further reduced, and the user experience can be improved.
