[0001] This application relates to the field of smart home appliance technology, such as a method and apparatus for controlling a fan, an air conditioner, and a storage medium. Background Technology

[0002] Currently, in pursuit of greater airflow and longer air delivery distance, air conditioners often feature large indoor unit air outlet grilles, leading to reduced grille strength. Furthermore, ABS (Acrylonitrile Butadiene Styrene plastic), used in its injection molding, has insufficient heat resistance. Therefore, during heating mode operation, prolonged exposure to high-temperature hot air can cause thermal stress concentration, distortion, and even localized breakage of the air outlet grille, ultimately affecting the airflow angle.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] Although the above solution increases the strength of the air outlet grille by reinforcing it, it still cannot eliminate the impact of the air outlet grille deformation on the air supply angle of the air conditioner when the air outlet grille deforms due to prolonged overheating.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0008] This disclosure provides a method and apparatus for controlling a fan, an air conditioner, and a storage medium to ensure the air delivery capacity of the air conditioner when the air outlet grille is deformed.

[0009] In some embodiments, the above method is applied to an air conditioner; the air conditioner includes a plurality of indoor fans arranged longitudinally, each indoor fan being provided with an air outlet grille; the method includes: detecting a first angle value of the air outlet grille; if the first angle value is greater than an angle threshold, determining a target indoor fan corresponding to the area where the air outlet grille is located; controlling the rotation speed of the target indoor fan to decrease to a first set rotation speed, and adjusting the rotation speed of adjacent fans of the target indoor fan.

[0010] Optionally, adjusting the rotational speed of adjacent fans of the target indoor fan includes: obtaining the number of adjacent fans of the target indoor fan; and when the number is one, controlling the rotational speed of the adjacent fans to increase to a second set rotational speed.

[0011] Optionally, the air conditioner further includes an air guide plate for adjusting the air supply direction; if the first angle value is greater than the angle threshold, it further includes: acquiring the location information of the indoor user; and adjusting the air supply angle of the air guide plate according to the location information to reduce the heat at the air outlet grille.

[0012] Optionally, when the quantity is one, the method further includes: obtaining the theoretical speed of the adjacent fan according to the first set speed; correcting the theoretical speed of the adjacent fan according to the air delivery angle of the guide vane to obtain the corrected speed of the adjacent fan; and configuring the corrected speed of the adjacent fan as the second set speed.

[0013] Optionally, adjusting the speed of adjacent fans of the target indoor fan further includes: when the number value is greater than one, determining the air supply strategy based on the location information of the indoor user and the first set speed of the target indoor fan; and adjusting the speed of each adjacent fan according to the air supply strategy.

[0014] Optionally, after determining the target indoor fan corresponding to the area where the air outlet grille is located, the method further includes: obtaining the air outlet temperature value of the air conditioner; and determining a first set speed based on the air outlet temperature value.

[0015] Optionally, after the indoor fan speed adjustment is completed, the method further includes: detecting the second angle value of the air outlet grille when the set running time is longer than the time threshold; and controlling the air conditioner to stop operating in heating mode and sending a warning message when the second angle value is greater than the set angle value.

[0016] In some embodiments, the above-described apparatus includes a processor and a memory storing program instructions, the processor being configured to execute, when running the program instructions, the method for controlling a fan as described above.

[0017] In some embodiments, the air conditioner includes: an air conditioner body; multiple indoor fans arranged longitudinally; multiple air outlet grilles corresponding to the indoor fans; and a device for controlling the fans as described above, which is installed on the air conditioner body.

[0018] In some embodiments, the storage medium stores program instructions that, when executed, perform the method for controlling the fan as described above.

[0019] The method and apparatus for controlling a fan, air conditioner, and storage medium provided in the embodiments of this disclosure can achieve the following technical effects:

[0020] The degree of deformation of the air outlet grille is determined by detecting its first angle value. If the first angle value exceeds a threshold, the grille is considered significantly deformed, potentially affecting the airflow angle of the air conditioner. In this case, the target indoor fan corresponding to the area of ​​the grille is identified, and its speed is adjusted to alleviate the deformation or allow it to recover to some extent. Therefore, the target indoor fan's speed is reduced by a first set speed from its current speed to decrease heat at the grille. Simultaneously, to ensure that the airflow volume and range do not fluctuate significantly, the speeds of adjacent fans to the target indoor fan are adjusted. This effectively ensures the air conditioner's airflow capacity even when the grille is deformed.

[0035] To provide a more detailed understanding of the features and technical content of the embodiments of this disclosure, the implementation of the embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for illustrative purposes only and are not intended to limit the embodiments of this disclosure. In the following technical description, for ease of explanation, several details are used to provide a full understanding of the disclosed embodiments. However, one or more embodiments may still be implemented without these details. In other cases, well-known structures and devices may be simplified in their depiction to simplify the drawings.

It should be understood that such data can be interchanged where appropriate for the embodiments of this disclosure described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0037] Unless otherwise stated, the term "multiple" means two or more.

[0038] In this embodiment of the disclosure, the character " / " indicates that the objects before and after it are in an "or" relationship. For example, A / B means: A or B.

[0039] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0040] The term "correspondence" can refer to an association or binding relationship. The correspondence between A and B means that there is an association or binding relationship between A and B.

[0041] In addition, the term "settings" should be interpreted broadly.

[0042] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0043] In the disclosed embodiments, the terminal device refers to an electronic device with wireless connectivity. The terminal device can communicate with smart home appliances via the internet, or directly via Bluetooth, WiFi, or other methods. In some embodiments, the terminal device may be, for example, a mobile device, a computer, or an in-vehicle device built into a hovercraft, or any combination thereof. Mobile devices may include, for example, mobile phones, smart home devices, wearable devices, smart mobile devices, virtual reality devices, or any combination thereof. Wearable devices may include, for example, smartwatches, smart bracelets, pedometers, etc.

[0044] Combination Figure 1 As shown, this embodiment of the present disclosure provides an air conditioner, including a plurality of indoor fans 20 arranged longitudinally within the air conditioner body 10, each indoor fan 20 having a corresponding air outlet grille 30. Specifically, the plurality of indoor fans include a first indoor fan 21, a second indoor fan 22, a third indoor fan 23, and a fourth indoor fan 24. Correspondingly, a first air outlet grille 31 is provided on the outside of the first indoor fan 21, a second air outlet grille 32 is provided on the outside of the second indoor fan 22, a third air outlet grille 33 is provided on the outside of the third indoor fan 23, and a fourth air outlet grille 34 is provided on the outside of the fourth indoor fan 24.

[0045] In addition, the aforementioned air conditioner also includes an air guide plate, an angle sensor, and a processor. The air guide plate can be positioned between the indoor fan 20 and the air outlet grille 30, or it can be positioned outside the air outlet grille 30. Alternatively, one air guide plate can be positioned between the indoor fan 20 and the air outlet grille 30, and another can be positioned outside the air outlet grille 30 to adjust different directions. For example, an air guide plate for adjusting vertical airflow can be positioned between the indoor fan 20 and the air outlet grille 30, while an air guide plate for adjusting horizontal airflow can be positioned outside the air outlet grille 30. Therefore, the specific installation position of the air guide plate is not limited here. The angle sensor is used to detect the angle value of the air outlet grille 30. Preferably, an angle sensor can be installed at each air outlet grille 30 to detect only that grille, or a single sensor can be used to detect the angle values ​​of all air outlet grilles 30. The processor is electrically connected to the angle sensor, each indoor fan 20, and the air guide plate. It processes the detected values ​​from the angle sensor and other relevant parameters, and adjusts the rotation speed of each indoor fan 20 and the air delivery angle of the air guide plate based on the processing results.

[0046] Combination Figure 1 As shown, this disclosure provides a method for controlling a fan. Figure 2 As shown, the above method includes:

[0047] S210, the processor detects the first angle value of the air grille.

[0048] S220, if the first angle value is greater than the angle threshold, the processor determines the target indoor fan corresponding to the area where the air outlet grille is located.

[0049] S230, the processor controls the target indoor fan speed to decrease to a first set speed, and adjusts the speed of the adjacent fans of the target indoor fan.

[0050] The angle threshold is used to characterize the maximum deformation angle that is insufficient to affect the air supply angle of the air outlet grille. It can be an angle value determined by the product model according to a preset first correspondence; or it can be an angle value determined by a second correspondence based on the air outlet grille angle value obtained when the air conditioner is first turned on.

[0051] The first angle value of the air outlet grille is the bending deformation angle of the vertical grille bars after heating, compared to the normal state. That is, the angle formed by the grille bars on the air outlet grille and the vertical reference plane. Specifically, it can be measured at the intersection of horizontally and vertically arranged grille bars, in heating mode, the angle formed by the vertically arranged grille bars and the vertical reference plane.

[0052] The method for controlling the fan provided in this embodiment effectively ensures the air delivery capacity of the air conditioner. By detecting a first angle value of the air outlet grille, the degree of deformation of the grille is determined. If the first angle value is greater than an angle threshold, it is determined that the air outlet grille is significantly deformed, potentially affecting the air delivery angle of the air conditioner. Due to the thermal expansion and contraction properties of ABS plastic, the target indoor fan corresponding to the area where the air outlet grille is located is identified, and the speed of the target indoor fan is adjusted to alleviate the deformation or allow it to recover to some extent. Therefore, the target indoor fan is controlled to reduce its speed by a first set value from its current speed to reduce heat at the air outlet grille. Simultaneously, to ensure that the air volume and air delivery range do not fluctuate significantly, the speeds of adjacent fans to the target indoor fan are adjusted synchronously. Thus, the air delivery capacity of the air conditioner is effectively guaranteed even when the air outlet grille is deformed.

[0053] Optionally, the processor adjusts the rotational speed of adjacent fans of the target indoor fan, including: the processor acquiring a value representing the number of adjacent fans of the target indoor fan. If the value is one, the processor controls the rotational speed of the adjacent fans to increase to a second set rotational speed.

[0054] This allows for better adjustment of the rotational speed of adjacent fans, thus mitigating the impact of a decrease in target wind speed. Figure 1 Taking the indoor fan layout shown as an example, with only a single row of indoor fans, the first indoor fan at the top and the fourth indoor fan at the bottom are only single adjacent fans. In this case, to ensure the air volume of the air conditioner without causing significant fluctuations in heating efficiency, the fan speed is increased to a second set speed to compensate for the decrease in the target fan speed. Thus, while the target fan speed decreases, the air volume of the air conditioner is kept within a certain range, thereby ensuring the heating efficiency of the air conditioner. The second set speed is positively correlated with the first set speed. Furthermore, without considering the user experience, the most computationally efficient method is to set the second set speed to the same value as the first set speed.

[0055] Combination Figure 3 As shown in the embodiments of this disclosure, another method for controlling a fan is provided, including:

[0056] S310, the processor detects the first angle value of the air grille.

[0057] S320, if the first angle value is greater than the angle threshold, the processor determines the target indoor fan corresponding to the area where the air outlet grille is located.

[0058] S330, the processor obtains the location information of indoor users.

[0059] The S340 processor adjusts the airflow angle of the air deflector based on location information to reduce heat at the air outlet grille.

[0060] S350, the processor controls the target indoor fan speed to decrease to a first set speed, and adjusts the speed of the adjacent fans of the target indoor fan.

[0061] The method for controlling a fan provided in this embodiment can ensure a better user experience while simultaneously releasing heat concentrated at the air outlet grille by adjusting the air delivery angle of the air guide plate. Since the current outlet air temperature is high, the air delivery angle of the air guide plate can be adjusted based on the location information of the indoor user to avoid discomfort caused by direct airflow. For example, while reducing the target indoor fan speed, the air outlet area of ​​the air guide plate at the air outlet grille can be increased to reduce heat at the deformed air outlet grille and promote its recovery.

[0062] Preferably, the maximum airflow speed and highest airflow temperature acceptable to the current user can be determined based on the user's identity information. Then, based on the maximum airflow speed and highest airflow temperature, the airflow angle of the air guide plate can be further adjusted to suit the user's usage habits and improve the user experience.

[0063] Optionally, when the quantity is one, the air conditioner obtains the theoretical speed of the adjacent fan based on the first set speed. The air conditioner then corrects the theoretical speed of the adjacent fan based on the airflow angle of the air guide vane to obtain the corrected speed of the adjacent fan. The air conditioner configures the corrected speed of the adjacent fan as the second set speed.

[0064] This approach mitigates the deformation of the air outlet grille while ensuring an uninterrupted user experience. A second set speed for the adjacent fans is determined based on the first set speed and the airflow angle of the guide vane. This balances airflow volume with the air conditioner's heating and airflow range, maintaining a comfortable user experience even with grille deformation.

[0065] Combination Figure 4 As shown in the embodiments of this disclosure, another method for controlling a fan is provided, including:

[0066] S410, the processor detects the first angle value of the air grille.

[0067] S420, the processor determines whether the first angle value is greater than the angle threshold. If yes, proceed to step S421; otherwise, return to step S410.

[0068] S421, the processor determines the target indoor fan corresponding to the area where the air outlet grille is located.

[0069] S422, the processor controls the target indoor fan speed to decrease to the first set speed.

[0070] S430, the processor obtains the number of adjacent fans of the target indoor fan.

[0071] S431, the processor determines whether the number of adjacent fans is greater than one. If yes, proceed to step S432; otherwise, proceed to step S434.

[0072] S432, the processor determines the air supply strategy based on the location information of the indoor user and the first set speed of the target indoor fan.

[0073] The S433 processor adjusts the speed of each adjacent fan according to the air supply strategy.

[0074] S434, the processor determines the second set speed based on the air delivery angle of the air guide plate and the first set speed of the target indoor fan.

[0075] S435, the processor controls the speed of the adjacent fan to increase the second set speed.

[0076] S440, the processor determines whether the air conditioner is performing heating operation. If yes, return to step S410; otherwise, proceed to step S450.

[0077] S450, the processor controls the air conditioner to stop working and records the first angle value.

[0078] The method for controlling a fan provided in this embodiment can determine the degree of deformation of the first air outlet grille based on a first angle value. If the first angle value is detected to be greater than an angle threshold, deformation of the air outlet grille is determined. In this case, the rotational speed of the corresponding target indoor fan needs to be reduced, and the rotational speeds of adjacent fans of the target indoor fan are adjusted to ensure heating efficiency and air supply stability. Since the number of adjacent fans that can be used for coordinated adjustment varies depending on the location of the target indoor fan, the number of such fans also varies.

[0079] When there is only one adjacent fan, a single fan is needed to compensate for the airflow loss caused by the reduced speed of the target indoor fan, while also taking into account the impact on the air delivery range caused by the reduced airflow speed of the target indoor fan. Therefore, based on the air delivery angle of the air guide plate, the air delivery of the adjacent fan should be made to cover the original air delivery range as much as possible. At the same time, the required supplementary air delivery volume is calculated based on the first set speed, and then a second set speed of the adjacent fan that can maintain the corresponding air delivery range and air delivery volume of the air conditioner is determined.

[0080] When there is more than one adjacent fan, multiple fans can work together to share the losses caused by the reduction in speed of the target indoor fan. Figure 1 Taking the indoor fan layout shown as an example, with only a single row of indoor fans, the second and third indoor fans in the middle each have two adjacent fans. In this case, the required supplementary air volume can be determined based on the first set speed of the target indoor fan, and a reasonable air supply range can be determined based on the location information of the indoor users, thus obtaining the air supply strategy for the two adjacent fans. The air supply angle and outlet speed of the two fans can be the same or different. Compared to a single adjacent target indoor fan, this allows for more flexible combination and adjustment methods. For example, to save computational resources, the speed of each of the two fans can be increased by half of the first set speed, that is, by increasing the air volume reduced by the first indoor fan by half with each of the two fans. This ensures the stability of the total air volume output of the air conditioner.

[0081] Optionally, after the processor determines the target indoor fan corresponding to the area where the grille is located, the processor obtains the air outlet temperature value of the air conditioner. The processor determines the first set speed based on the air outlet temperature value.

[0082] In this way, a first set rotation speed can be determined to more significantly reduce the effect of the air outlet grille, based on the actual outlet air temperature. The first set rotation speed corresponding to the outlet air temperature value can be determined according to a preset chart. The first set rotation speed and the outlet air temperature value are positively correlated numerically.

[0083] Combination Figure 5 As shown in the embodiments of this disclosure, another method for controlling a fan is provided, including:

[0084] S510, the processor detects the first angle value of the air grille.

[0085] S520, if the first angle value is greater than the angle threshold, the processor determines the target indoor fan corresponding to the area where the air outlet grille is located.

[0086] S530, the processor controls the target indoor fan speed to decrease to a first set speed, and adjusts the speed of the adjacent fans of the target indoor fan.

[0087] When the S540 runs for a duration longer than the set duration threshold, the processor detects the second angle value of the air grille.

[0088] S550: If the second angle value is greater than the set angle value, the processor controls the air conditioner to stop operating in heating mode and sends a warning message.

[0089] The set angle value is used to characterize the maximum angle value that the air outlet grille can theoretically reach after speed adjustment.

[0090] The method for controlling the fan provided in this disclosure can promptly alert the user to the current strength of the air outlet grille. The running time of the air conditioner after adjusting the indoor fan speed is obtained to further determine the deformation of the air outlet grille. If the running time exceeds a set threshold, it is determined that the deformation of the air outlet grille has been somewhat alleviated or recovered. At this time, the deformation of the air outlet grille is determined by detecting a second angle value. If the second angle value is greater than a set angle value, it is determined that the deformation of the air outlet grille may be irreversible. At this time, the air conditioner is controlled to stop operating in heating mode and a warning message is sent to inform the user of the risk and suggest that the user check the actual condition of the air outlet grille.

[0091] Sending warning information can be done by playing relevant audio information through a fixed air conditioner, displaying relevant text information and / or icons through the air conditioner's display device, providing certain pop-up prompts on mobile devices through software, or any combination of the above methods.
