Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and in particular to a method for controlling an air conditioning swing motor. Background Technology

[0002] The speed of the sweeping motor directly affects the rate of change of the load on the internal fan. If the sweeping motor speed is too fast, the sweeping speed will be too fast, causing the load on the internal fan to change rapidly. The speed adjustment program of the internal fan cannot keep up with the rate of load change, resulting in fluctuations in the speed of the internal fan. This affects the smoothness and stability of airflow, generates blowing noise, and affects normal use by the user. Conversely, if the sweeping motor speed is slowed down, the sweeping speed will also be slower, and the load change of the internal fan will be slower. The speed adjustment program of the internal fan can keep up with the rate of change in time and adjust the speed of the internal fan in a timely manner, thereby reducing the fluctuation of the internal fan speed.

[0003] In the prior art, the patent with publication number CN105066328B (Air Conditioner Sweep Control Method and System) proposes to detect the current position of the air conditioner's air guide device; determine the current sweep area of ​​the air conditioner based on the current position; and adjust the rotation speed of the air conditioner's air guide device based on the current sweep area.

[0004] The aforementioned prior art has the following disadvantages:

[0005] This solution cannot determine whether the real-time speed of the internal fan exceeds the fluctuation range. It only adjusts the speed of the sweeping motor based on the preset mapping relationship between the sweeping area and the speed of the air guide device. The adjustment accuracy is not high, which can easily affect the stability of the air outlet and generate blowing noise that affects the user's normal use. Summary of the Invention

[0006] To overcome the problems existing in related technologies, this application provides an air conditioner swing motor control method. This air conditioner swing motor control method can improve the accuracy of the swing motor speed, reduce the fluctuation of the indoor fan speed, improve the air outlet stability of the indoor fan, and improve user comfort.

[0007] This application provides a method for controlling an air conditioner swing motor, including:

[0008] Obtain the real-time speed of the indoor fan corresponding to the N sweeping zones of the air conditioning sweeping mechanism, where N is greater than or equal to 2;

[0009] Compare the real-time speed of the internal fan with the target speed range, and determine whether there is any abnormality in the real-time speed of the internal fan based on the comparison results;

[0010] If the current real-time speed of the internal fan is abnormal, the number of abnormalities in the sweeping area corresponding to the current real-time speed of the internal fan will be counted.

[0011] The area where the number of abnormal occurrences reaches the abnormal threshold is marked as an abnormal sweeping area;

[0012] When the air conditioning sweep mechanism operates in an abnormal sweep area, reduce the speed of the air conditioning sweep motor.

[0013] In one implementation, the sweeping area where the number of abnormal occurrences reaches an abnormal threshold is marked as an abnormal sweeping area, including:

[0014] If the number of abnormal occurrences in the same swept area reaches the abnormal threshold within M consecutive swept cycles, the swept area with the number of abnormal occurrences reaching the abnormal threshold is marked as a swept abnormal area; M is greater than 1.

[0015] The N sweep zones include the starting sweep zone and the ending sweep zone, and there are N-2 sweep zones between the starting sweep zone and the ending sweep zone.

[0016] The air sweep cycle is the process by which the air conditioning air sweep mechanism moves from the initial air sweep area to the final air sweep area and then back from the final air sweep area to the initial air sweep area.

[0017] In one implementation, before obtaining the real-time rotational speeds of the indoor fans corresponding to the N sweeping zones of the air conditioning sweeping mechanism, the process includes:

[0018] Control the air conditioner's air sweeping mechanism and the air conditioner's internal fan to operate according to the air conditioner's preset operating strategy for a first duration, where the first duration is greater than zero.

[0019] In one implementation, obtaining the real-time rotational speed of the indoor fan corresponding to each of the N sweeping zones of the air conditioning sweeping mechanism includes:

[0020] When the air conditioning sweep mechanism operates according to the preset operating strategy for a certain period of time and reaches the starting sweep area, it begins to acquire the real-time speed of the internal fan in each sweep area from the starting sweep area to the ending sweep area.

[0021] In one embodiment, reducing the speed of the sweeping motor of the air conditioning sweeping mechanism includes:

[0022] The speed of the sweeping motor is reduced to the first adjustment speed, which is the speed obtained by reducing the speed of the sweeping motor by a preset adjustment speed. The preset adjustment speed is the preset adjustment speed threshold of the sweeping motor.

[0023] In one embodiment, after reducing the speed of the sweeping motor to a first adjusted speed, the process includes:

[0024] If, during the M+1th sweep cycle, the real-time speed of the indoor fan does not match the target speed range when the air conditioning sweep mechanism is operating in the abnormal sweep zone, the first adjustment speed will be reduced to the second adjustment speed; if the real-time speed of the indoor fan matches the target speed range when the air conditioning sweep mechanism is operating in the abnormal sweep zone, the first adjustment speed will be maintained.

[0025] The (M+1)th sweeping cycle is the next sweeping cycle after a continuous M sweeping cycles, and the second adjustment speed is the speed obtained by reducing the preset adjustment speed by adjusting the first adjustment speed.

[0026] In one embodiment, after reducing the first adjustment speed to the second adjustment speed, the process includes:

[0027] If, during the M+2nd sweep cycle, the real-time speed of the indoor fan does not match the target speed range when the air conditioning sweep mechanism is operating in the abnormal sweep zone, the second adjustment speed will be reduced to the lower limit speed of the sweep motor; if the real-time speed of the indoor fan matches the target speed range when the air conditioning sweep mechanism is operating in the abnormal sweep zone, the second adjustment speed will be maintained.

[0028] The (M+2)th sweeping cycle is the next sweeping cycle after the (M+1)th sweeping cycle, and the lower limit speed of the sweeping motor is the preset minimum speed of the sweeping motor.

[0029] In one embodiment, reducing the speed of the sweeping motor of the air conditioning sweeping mechanism further includes:

[0030] The number of abnormal sweeping areas is compared with the abnormal number threshold. If the number of abnormal sweeping areas is greater than the abnormal number threshold, the sweeping motor speed is reduced to the lower limit speed of the sweeping motor starting from the (M+1)th sweeping cycle.

[0031] In one implementation, the target rotational speed range includes an upper limit value and a lower limit value.

[0032] Compare the real-time speed of the internal fan with the target speed range, including:

[0033] The upper limit of the target range is obtained by summing the preset internal fan speed and the preset deviation speed.

[0034] Subtract the preset deviation speed from the preset internal fan speed to obtain the lower limit of the target range;

[0035] The preset indoor fan speed is the standard speed preset for the indoor fan of the air conditioner, and the preset deviation speed is the correction value for the standard speed;

[0036] Compare the real-time speed of the internal fan with the upper limit and lower limit of the target range.

[0037] In one implementation, determining whether there is an abnormality in the real-time speed of the internal fan based on the comparison results includes:

[0038] If the real-time speed of the internal fan is greater than the upper limit of the target range, or if the real-time speed of the internal fan is less than the lower limit of the target range, then it is determined that the real-time speed of the internal fan is abnormal.

[0039] If the real-time speed of the internal fan is greater than or equal to the lower limit of the target range and less than or equal to the upper limit of the target range, then the real-time speed of the internal fan is considered to be normal.

[0040] The technical solution provided in this application may include the following beneficial effects:

[0041] By acquiring the real-time rotational speeds of the indoor fans corresponding to N sweeping zones of the air conditioning sweeping mechanism, and comparing these real-time rotational speeds with the target rotational speed range, the system determines whether there are any anomalies in the real-time rotational speeds of the indoor fans. If an anomaly is found, the number of anomalies in the sweeping zone corresponding to that rotational speed is counted, and sweeping zones with an anomaly count reaching an anomaly threshold are marked as abnormal sweeping zones. This effectively filters out abnormal sweeping zones where the real-time rotational speed of the indoor fans fluctuates, allowing for targeted adjustments to the sweeping speed when the air conditioning sweeping mechanism operates within an abnormal sweeping zone. Adjustments are made, and because the speed of the sweeping motor decreases, the sweeping speed also slows down, and the load change of the indoor fan is also slower. The response speed of the indoor fan speed adjustment program can keep up with the speed of load change in a timely manner, thereby adjusting the indoor fan speed in a timely manner to reduce the fluctuation of the indoor fan speed. Therefore, when the air conditioning sweeping mechanism operates in the abnormal sweeping area, the speed of the sweeping motor of the air conditioning sweeping mechanism is reduced, the accuracy of the sweeping motor speed is improved, the fluctuation of the indoor fan speed is reduced, the smoothness and stability of the indoor fan airflow are improved, the blowing noise is avoided, and the user comfort is improved.

[0048] Preferred embodiments of the present application will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present application are shown in the drawings, it should be understood that the present application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the present application more thorough and complete, and to fully convey the scope of the present application to those skilled in the art.

[0049] The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The singular forms “a,” “the,” and “the” used in this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0050] It should be understood that although the terms "first," "second," "third," etc., may be used in this application to describe various information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this application, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0051] Example 1

[0052] The speed of the sweeping motor directly affects the rate of load change of the internal fan. If the sweeping motor speed is too fast, the sweeping speed will be too fast, causing the load change of the internal fan to be faster. The response speed of the internal fan speed adjustment program cannot keep up with the load change rate, resulting in fluctuations in the internal fan speed. This affects the smoothness and stability of airflow, generates blowing noise, and disrupts normal use. Current technology cannot determine whether the real-time speed of the internal fan exceeds the fluctuation range. It only adjusts the sweeping motor speed based on the preset mapping relationship between the sweeping area and the speed of the air guide device. The adjustment accuracy is not high, which can easily affect the stability of airflow and generate blowing noise, affecting normal use.

[0053] To address the aforementioned issues, this application provides an air conditioning swing motor control method that can improve the accuracy of the swing motor speed, reduce fluctuations in the indoor fan speed, improve the stability of the indoor fan's airflow, and enhance user comfort.

[0054] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0055] Please see Figure 1 The first embodiment of the air conditioning swing motor control method shown in this application includes:

[0056] 101. Obtain the real-time speed of the indoor fan corresponding to each of the N sweeping zones of the air conditioning sweeping mechanism;

[0057] An air-conditioning sweep mechanism is a device that guides the direction of airflow from the air conditioner's internal fan. An air-conditioning sweep mechanism may include, but is not limited to, a sweep mechanism that changes the horizontal direction of the airflow and a sweep mechanism that changes the vertical direction of the airflow.

[0058] The full-angle sweeping range of the air conditioning sweeping mechanism is divided into N sweeping zones, each with a corresponding sweeping angle. The division can be achieved by evenly dividing the full-angle sweeping range so that each zone has the same sweeping angle. For example, assuming the full-angle sweeping range of the air conditioning sweeping mechanism is 10° to 80°, if the full-angle sweeping range is evenly divided into 8 sweeping zones, then each sweeping zone corresponds to a sweeping angle of 10°. It is understood that there are various ways to divide the full-angle sweeping range, and the number of sweeping zones obtained is also varied. In practical applications, a suitable division method and a suitable number of sweeping zones need to be determined based on the specific application. Setting the number of sweeping zones to at least two is sufficient; no single limitation is imposed here.

[0059] Furthermore, the rotational speed of the indoor fan is monitored when the air-conditioning sweeping mechanism reaches each sweeping zone to obtain the real-time rotational speed of the indoor fan. The monitoring method can be to use a speed measuring instrument or to retrieve the indoor fan speed data stored in the air-conditioning controller. There is no single limitation on the monitoring method.

[0060] 102. Compare the real-time speed of the internal fan with the target speed range, and determine whether there is any abnormality in the real-time speed of the internal fan based on the comparison results;

[0061] The speed of the indoor fan in an air conditioner is not constant. For example, the air conditioner controller intelligently regulates the speed of the indoor fan to keep it within the target speed range. However, when the air sweeping mechanism moves too fast, it affects the rate of change of the indoor fan load, causing fluctuations in the real-time speed of the indoor fan. In this case, it is necessary to determine whether the fluctuation exceeds the target speed range. If it is still within the target speed range, the real-time speed of the indoor fan is considered normal. If it exceeds the target speed range, the real-time speed of the indoor fan is considered abnormal, and it is necessary to further determine whether to reduce the sweeping speed of the air sweeping mechanism to reduce the fluctuation range of the indoor fan's real-time speed.

[0062] 103. If the current real-time speed of the internal fan is abnormal, the number of abnormalities in the sweeping area corresponding to the current real-time speed of the internal fan will be counted.

[0063] If an abnormality is detected in the real-time speed of the indoor fan, the sweeping area of ​​the air conditioning sweeping mechanism can be determined by detecting the sweeping angle of the current air conditioning sweeping mechanism. This sweeping area is then recorded, and the number of abnormalities is counted based on the number of records. In this embodiment, the sweeping area with an abnormal real-time speed of the indoor fan is recorded once within one sweeping cycle. The number of abnormalities within one sweeping cycle is then counted as 1. The sweeping cycle is the process of moving from the initial sweeping area to the final sweeping area and back again. It is understood that there are various ways to set the number of records within one sweeping cycle, and the appropriate setting should be determined according to the actual application. No single setting is specified here.

[0064] 104. Mark the sweeping area where the number of abnormal occurrences reaches the abnormal threshold as an abnormal sweeping area;

[0065] In this embodiment, an anomaly threshold is preset to determine whether a swept area needs to be marked as an abnormal swept area. Specifically, if the number of anomalies is greater than or equal to the anomaly threshold, the swept area is marked as an abnormal swept area; conversely, if the number of anomalies is less than the anomaly threshold, the swept area is not marked as an abnormal swept area. It is understood that the number of anomalies can be within a specified number of swept cycles, or it can be without a limit on the number of swept cycles, or it can be within a consecutive number of swept cycles; there is no single limitation.

[0066] 105. When the air conditioner sweeping mechanism operates in an abnormal sweeping area, reduce the speed of the air conditioner sweeping motor.

[0067] When the air conditioning swing mechanism operates in the abnormal swing area, it means that the swing speed of the air conditioning swing mechanism needs to be reduced to reduce the fluctuation range caused by the real-time speed of the indoor fan. Since the air conditioning swing mechanism is driven by the swing motor, reducing the speed of the swing motor of the air conditioning swing mechanism will reduce the swing speed of the air conditioning swing mechanism.

[0068] The following beneficial effects can be seen from the above embodiment one:

[0069] By acquiring the real-time rotational speeds of the indoor fans corresponding to N sweeping zones of the air conditioning sweeping mechanism, and comparing these real-time rotational speeds with the target rotational speed range, the system determines whether there are any anomalies in the real-time rotational speeds of the indoor fans. If an anomaly is found, the number of anomalies in the sweeping zone corresponding to that rotational speed is counted, and sweeping zones with an anomaly count reaching an anomaly threshold are marked as abnormal sweeping zones. This effectively filters out abnormal sweeping zones where the real-time rotational speed of the indoor fans fluctuates, allowing for targeted adjustments to the sweeping speed when the air conditioning sweeping mechanism operates within an abnormal sweeping zone. Adjustments are made, and because the speed of the sweeping motor decreases, the sweeping speed also slows down, and the load change of the indoor fan is also slower. The response speed of the indoor fan speed adjustment program can keep up with the speed of load change in a timely manner, thereby adjusting the indoor fan speed in a timely manner to reduce the fluctuation of the indoor fan speed. Therefore, when the air conditioning sweeping mechanism operates in the abnormal sweeping area, the speed of the sweeping motor of the air conditioning sweeping mechanism is reduced, the accuracy of the sweeping motor speed is improved, the fluctuation of the indoor fan speed is reduced, the smoothness and stability of the indoor fan airflow are improved, the blowing noise is avoided, and the user comfort is improved.

[0070] Example 2

[0071] To facilitate understanding, an embodiment of the air conditioner swing motor control method is provided below. In practical applications, if the number of abnormal occurrences in the same swing area reaches the abnormal threshold within M consecutive swing cycles, the swing area is marked as an abnormal swing area. This improves the accuracy of marking abnormal swing areas and avoids incorrect marking of abnormal swing areas, which could affect the operation of the air conditioner and the comfort of the user.

[0072] Please see Figure 2 Embodiment two of the air conditioning swing motor control method shown in this application includes:

[0073] 201. Control the air conditioner's air sweeping mechanism and the air conditioner's indoor fan to operate according to the air conditioner's preset operating strategy for the first duration;

[0074] Before obtaining the real-time speed of the indoor fans corresponding to the N sweeping zones of the air conditioning sweeping mechanism, it is necessary to start the air conditioning and control the air conditioning sweeping mechanism and indoor fans to operate according to the preset operating strategy of the air conditioning for a first period of time, so that the air conditioning sweeping mechanism and indoor fans enter the preset operating state. This avoids obtaining the real-time speed of the indoor fans corresponding to the N sweeping zones of the air conditioning sweeping mechanism before the air conditioning sweeping mechanism and indoor fans have entered the preset operating state in the short time after the air conditioning is started, which may easily lead to inaccurate real-time speed of the indoor fans and cause control errors.

[0075] In the embodiments of this application, the first duration is greater than zero, and the first duration can be set to 2 minutes. It is understood that there are various ways to set the duration of the first duration. In practical applications, the duration setting method needs to be determined according to the actual application situation. There is no unique limitation here.

[0076] 202. Obtain the real-time speed of the indoor fan corresponding to each of the N sweeping zones of the air conditioning sweeping mechanism;

[0077] In this embodiment of the application, the N sweeping areas include the starting sweeping area and the ending sweeping area. It can be understood that there are N-2 sweeping areas between the starting sweeping area and the ending sweeping area.

[0078] The sweep cycle is the process by which the air conditioning sweep mechanism moves from the initial sweep area to the final sweep area and back again. In other words, one sweep cycle is defined as the air conditioning sweep mechanism starting from and returning to the initial sweep area. It is understood that the sweep cycle can be set in various ways. In practical applications, it can also be set as the process of the air conditioning sweep mechanism moving from the initial sweep area to the final sweep area. The method of setting the sweep cycle needs to be determined based on the actual application conditions; no single limitation is set here.

[0079] When the air conditioning sweep mechanism operates for the first time according to the preset operating strategy and reaches the starting sweep area, it begins to acquire the real-time speed of the indoor fan in each sweep area from the starting sweep area to the ending sweep area, ensuring the integrity of the real-time speed of the indoor fan acquired in each sweep area during a sweep cycle.

[0080] 203. Compare the real-time speed of the internal fan with the target speed range, and determine whether there is any abnormality in the real-time speed of the internal fan based on the comparison results;

[0081] In this embodiment, the target speed range includes an upper limit and a lower limit. The upper limit of the target range is obtained by summing the preset internal fan speed and the preset deviation speed. The lower limit of the target range is obtained by subtracting the preset deviation speed from the preset internal fan speed. The preset internal fan speed is the preset standard speed of the air conditioner's internal fan, and the preset deviation speed is a correction value for the standard speed. It can be understood as the correction value for the air conditioner's controller to intelligently regulate the standard speed of the air conditioner's internal fan.

[0082] Compare the real-time speed of the internal fan with the upper and lower limits of the target range. If the real-time speed of the internal fan is greater than the upper limit of the target range, or less than the lower limit of the target range, it means that the real-time speed of the internal fan exceeds the target speed range, and it is determined that the real-time speed of the internal fan is abnormal. If the real-time speed of the internal fan is greater than or equal to the lower limit of the target range and less than or equal to the upper limit of the target range, it means that the real-time speed of the internal fan is within the target speed range, and it is determined that the real-time speed of the internal fan is normal.

[0083] 204. Within M consecutive sweep cycles, the sweep area where the number of abnormal occurrences reaches the abnormal threshold is marked as an abnormal sweep area.

[0084] In this embodiment, if the number of abnormal occurrences in the same swept area reaches an abnormal threshold within M consecutive swept cycles, the swept area is marked as an abnormal swept area. This avoids the situation where the real-time speed of the internal fan in a swept area occasionally exceeds the target speed range, but the number of abnormal occurrences reaches the abnormal threshold and is thus marked as an abnormal swept area. This effectively improves the accuracy of marking abnormal swept areas and avoids marking errors. The value of M is an integer greater than 1, and can be set between 3 and 5. Preferably, the value of M is 3. Correspondingly, the abnormal threshold can be set to the same value as M, or it can be different. Preferably, the abnormal threshold can be set to 3. It is understood that the value of M and the setting method of the abnormal threshold are diverse. In practical applications, the value of M and the setting method of the abnormal threshold need to be determined according to the actual application situation. There is no unique limitation here.

[0085] The following beneficial effects can be seen from the above embodiment two:

[0086] By acquiring the real-time speed of the indoor fan corresponding to each of the N sweeping zones of the air conditioning sweeping mechanism when the air conditioning sweeping mechanism and the indoor fan of the air conditioning enter the preset operating state, and by marking the sweeping zone as an abnormal sweeping zone if the number of abnormal times counted in the same sweeping zone reaches the abnormal threshold within M consecutive sweeping cycles, the accuracy of marking abnormal sweeping zones is improved, avoiding the situation of incorrect marking of abnormal sweeping zones, which would affect the operation of the air conditioning and the comfort of users.

[0087] Example 3

[0088] For ease of understanding, an embodiment of the air conditioner sweep motor control method is provided below. In practical applications, the implementation method of reducing the speed of the air conditioner sweep motor when the air conditioner sweep mechanism runs to the abnormal sweep area will be further designed to improve the accuracy of the sweep motor speed.

[0089] Please see Figure 3 Embodiment three of the air conditioning swing motor control method shown in this application includes:

[0090] 301. When the air conditioner sweeping mechanism operates in the abnormal sweeping area, reduce the speed of the sweeping motor to the first adjustment speed;

[0091] When the air conditioning sweeping mechanism operates in the abnormal sweeping area, the sweeping motor speed is reduced to the first adjustment speed. The first adjustment speed is the speed obtained by reducing the sweeping motor speed by a preset adjustment speed. The preset adjustment speed is the preset adjustment speed threshold of the sweeping motor. The preset adjustment speed can be set to 20 revolutions per minute. It is understood that in actual application, the preset adjustment speed needs to be set according to the actual application situation, and there is no unique limitation here.

[0092] Understandably, the speed of the sweeping motor only decreases when the air conditioning sweeping mechanism operates in the abnormal sweeping area. After the air conditioning sweeping mechanism leaves the abnormal sweeping area and enters the next sweeping area, it sweeps according to the original sweeping motor speed corresponding to the next sweeping area. This allows for independent control of the sweeping motor speed corresponding to each sweeping area, thereby improving the accuracy of the sweeping motor speed.

[0093] 302. When the air conditioner's air sweeping mechanism operates in the abnormal air sweeping area, the real-time speed of the indoor fan does not match the target speed range, so the speed of the air sweeping motor is reduced from the first adjustment speed to the second adjustment speed.

[0094] The next sweep cycle after M consecutive sweep cycles is the (M+1)th sweep cycle. If, in the (M+1)th sweep cycle, the real-time speed of the indoor fan when the air conditioning sweep mechanism is in the abnormal sweep zone still does not match the target speed range (i.e., still exceeds the target speed range), then the first adjustment speed is reduced to the second adjustment speed, which is the speed obtained by reducing the first adjustment speed by a preset adjustment speed. When the real-time speed of the indoor fan when the air conditioning sweep mechanism is in the abnormal sweep zone matches the target speed range, then the first adjustment speed is maintained.

[0095] 303. When the air conditioner's air sweeping mechanism operates in the abnormal air sweeping area, the real-time speed of the indoor fan does not match the target speed range. The speed of the air sweeping motor is reduced from the second adjustment speed to the lower limit speed of the air sweeping motor.

[0096] The next sweep cycle after the (M+1)th sweep cycle is the (M+2)th sweep cycle. If, during the (M+2)th sweep cycle, the real-time speed of the indoor fan when the air conditioning sweep mechanism is in the abnormal sweep zone still does not match the target speed range (i.e., still exceeds the target speed range), then the second adjustment speed is reduced to the lower limit speed of the sweep motor, which is the minimum speed preset by the sweep motor. If the real-time speed of the indoor fan when the air conditioning sweep mechanism is in the abnormal sweep zone matches the target speed range, then the second adjustment speed is maintained.

[0097] 304. If the number of abnormal sweeping areas exceeds the abnormal number threshold, reduce the sweeping motor speed to the lower limit speed of the sweeping motor.

[0098] Within M consecutive sweeping cycles, the number of abnormal sweeping areas is compared with the abnormal number threshold. If the number of abnormal sweeping areas is greater than the abnormal number threshold, it means that there are too many abnormal sweeping areas. The sweeping motor speed will no longer be adjusted in depth. Starting from the (M+1)th sweeping cycle, the sweeping motor speed will be reduced to the lower limit speed of the sweeping motor. The sweeping motor will use the lower limit speed of the sweeping motor to perform sweeping operation in all sweeping areas.

[0099] Understandably, if the number of abnormal sweeping areas only exceeds the abnormality threshold in the (M+1)th sweeping cycle, then at the beginning of the next sweeping cycle, the sweeping motor speed will be reduced to the lower limit speed of the sweeping motor, and the sweeping motor will operate at the lower limit speed for all sweeping areas. In this embodiment, the abnormality threshold can be set to an integer value between 3 and 5, preferably 3, but this needs to be determined according to the actual application and is not a unique limitation here.

[0100] It is also understood that steps 301 to 303 in Embodiment 3 can be executed sequentially, while there is no strict time limit between step 304 and steps 301 to 303. Step 304 can be executed after any of steps 301 to 303, depending on the comparison result between the number of abnormal areas and the abnormal number threshold. No unique limitation is made here.

[0101] The following beneficial effects can be seen from the above embodiment three:

[0102] By setting the swing motor speed to decrease only when the air conditioning swing mechanism operates in the abnormal swing area, the swing motor speed corresponding to each swing area can be independently controlled, improving the accuracy of the swing motor speed, reducing the fluctuation of the indoor fan speed, improving the smoothness and stability of the indoor fan's airflow, avoiding blowing noise, and improving user comfort.
