[0002] With societal development, many electrical appliances require fans, such as air conditioners, cooling devices, and blowers. These fans are typically installed outdoors or in open spaces. If the wind is strong, the fan blades, even when the fan is off, will rotate at high speed due to the natural wind. If the user needs to turn it on, and the fan is rotating at a high speed and in reverse, it will fail to start, severely impacting user experience.

[0053] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0054] Figure 1 This is a flowchart illustrating a fan blade starting method provided in an embodiment of this application.

[0055] like Figure 1 As shown in the illustration, this application discloses an embodiment of a method for starting a fan blade, the method comprising:

[0056] S110: Obtain the rotation direction of the fan blades before starting the fan blades.

[0057] The fan blade starting method in this embodiment can be applied to fan devices with fan blades, such as air conditioners, cooling devices, and blowers. "Before starting the fan blades" can refer to the period from receiving a power-on command to the moment the fan blades start. The power-on command refers to a command received by the fan device, such as a remote control power-on command or a button power-on command. The fan device can power on according to the power-on command. It should be noted that "powering on" here only indicates that the fan device is powered on and running, not that the fan blades are running. For example, the fan device includes a main motor and fan blades. The main motor is the motor used to control the rotation of the fan blades. After the fan device is powered on, the main motor has not yet started, meaning the fan blades are not driven by the main motor to start. Next, upon receiving the power-on command, the rotation direction of the fan blades is obtained. The fan blades refer to the blades of the fan unit. The fan unit exchanges heat by starting and rotating the fan blades. Since the fan unit is usually set up outdoors or in an open location, the fan blades are affected by environmental factors before starting, causing the fan blades to rotate spontaneously. At this time, the rotation direction of the fan blades is random and disordered. If the fan blades are rotating in reverse and then the fan blades are started to rotate in the forward direction, or if the main motor is started to drive the fan blades to rotate in the forward direction, the two opposing forces acting on the fan blades will cause the fan blades to malfunction and thus fail to start. In this embodiment, after receiving the start command, before starting the fan blades, the rotation direction of the fan unit's fan blades is obtained to determine whether the fan blades are currently rotating in reverse. This ensures that the fan blades are started only when they are not rotating in reverse, thus achieving the effect of effective fan blade start-up.

[0058] In one embodiment, obtaining the rotation direction of the air conditioner's fan blades includes:

[0059] Acquire the first current signal, which represents the current value generated by the rotation of the fan blades;

[0060] The rotation direction of the fan blades is determined based on the first current signal.

[0061] In this embodiment, the current generated by the rotation of the fan blades is detected to determine the first current signal. Specifically, the first current signal can be obtained through a current sensor. Because the direction of the current generated will be different depending on the direction of the fan blade rotation, the rotation direction of the fan blades can be determined based on the sign of the first current signal. For example, if it is predetermined that the current is positive in the forward rotation direction and negative in the reverse rotation direction, then when the current represented by the first current signal is positive, it indicates that the rotation direction of the fan blades is positive; when the current represented by the first current signal is negative, it indicates that the rotation direction of the fan blades is reversed. More specifically, refer to... Figure 2 The current detection module detects the current value of one of the three phases (U, V, W). Taking the U-phase current detection as an example, the U terminal of the current sensor U1 is connected to the U-phase of the fan unit, and the Uout terminal is connected to the Uout output of the controller. Iu is the output current value of the current sensor. After voltage division by resistors R11 and R12 and filtering by capacitor C1, the current-voltage value is obtained as Uu = Iu × R12 / (R11 + R12). Uu is connected to the positive terminal of operational amplifier U2, and the negative terminal of U2 is connected to the output, forming a voltage follower U2. When the voltage at the output terminal of U2 is positive, the NPN transistor Q is turned on, outputting a high-level signal to the microcontroller unit (MCU). At this time, the MCU determines that the fan is rotating in the forward direction. When the voltage at the output terminal of U2 is negative, the NPN transistor Q is turned off, sending a low-level signal to the MCU. At this time, the MCU determines that the fan is rotating in the reverse direction. Thus, by using the different rotation directions of the fan blades to generate currents in different directions, the sign of the first current signal is determined, thereby determining the rotation direction of the fan blades.

[0062] In one embodiment, after determining whether the rotation direction is a reverse direction, the method further includes:

[0063] When the rotation direction is reversed, a fan blade adjustment command is generated. The fan blade adjustment command is used to indicate the angle between the plane where the fan blade is located and the fan blade's axis of rotation.

[0064] In this embodiment, if the main motor is directly started to drive the fan blades when the rotation direction is reversed, two forces will act on the fan blades, causing a fan blade rotation failure and resulting in the air conditioner failing to start. Therefore, when the rotation direction is reversed, a fan blade adjustment command can be generated. This command indicates the angle of the fan blades, which represents the angle between the plane of the fan blades and the axis of rotation. By changing the angle of the fan blades, the fan blades can obtain different rotational forces under the same external wind force, thus changing the direction of the force exerted on the fan blades by the natural wind. This allows the fan blades, which were originally rotating in reverse under natural wind, to rotate in the forward direction, thereby improving the success rate of the fan equipment startup and making the startup process safer and more reliable. (Reference) Figure 3-6 This means that when the fan blades are subjected to external wind force in the direction of A1, they will generate a rotational force in the direction of A2. The direction of A2 is the reverse direction. After adjusting the angle of the fan blades, the fan blades are still subjected to external wind force in the direction of A1, but at this time they will generate a rotational force in the direction of A3. The direction of A3 is not the reverse direction. Therefore, by changing the angle of the fan blades, the direction of rotation of the fan blades can be changed.

[0065] Since the blade adjustment command is used to indicate the adjustment of the blade angle, different external forces will require different angle adjustments. For example, if the external wind speed is too high and the blade angle is adjusted too small, there will be problems such as not being able to change the direction of blade rotation or requiring a long time to change the direction of blade rotation.

[0066] In one embodiment, when the rotation direction is reversed, adjusting the angle between the plane where the fan blade is located and the axis of rotation of the fan blade includes:

[0067] When the rotation direction is reversed, determine the wind speed information and the fan blade rotation speed information. The wind speed information represents the wind speed at the fan blade position, and the rotation speed information represents the speed at which the fan blade rotates.

[0068] Based on wind speed and rotation speed information, generate fan blade adjustment commands;

[0069] Based on the fan blade adjustment command, the angle between the plane where the fan blade is located and the fan blade's axis of rotation is adjusted.

[0070] In this embodiment, when the rotation direction is reversed, it is explained that directly starting the main motor to drive the fan blades will result in a fan blade rotation malfunction leading to startup failure. Therefore, it is necessary to adjust the angle of the fan blades to change the directional force generated by the external wind. The specific angle to be adjusted needs to be determined based on the wind speed and the current rotational speed of the fan blades, i.e., determining the wind speed information and the fan blade rotational speed information. The wind speed information is the wind speed of the external environment at the fan blade position, and the rotational speed information represents the current rotational speed of the fan blades. Because if the external wind speed is high and the current rotational speed of the fan blades is high, if the angle of the fan blades is adjusted too small, it may not be able to change the rotation of the fan blades. The issue is that the direction of the fan blade rotation may take a relatively long time to change, meaning that a larger adjustment angle is needed to achieve the desired effect. Then, based on wind speed and rotation speed information, a fan blade adjustment command is generated. Based on this command, the angle between the plane containing the fan blade and its rotation axis is adjusted. Specifically, the fan blade rotation speed (Sn) is detected, and the ambient wind speed (Sf) is detected. The fan blade adjustment angle θ = f(Sn, Sf), where f is a preset function, is calculated. The fan blade adjustment command is then generated based on this angle θ, thus instructing the fan blade to adjust by the angle θ.

[0071] In addition, the blade adjustment command can instruct the angle between the plane where the blade is located and the blade rotation axis to be adjusted to angle θ, or instruct the plane where the blade is located to rotate by angle θ from the current angle. When the blade adjustment command instructs the plane where the blade is located to rotate by angle θ from the current angle, the current angle of the blade needs to be specified. To ensure the accuracy of the adjustment angle, the blade angle can be pre-set to a preset angle before adjusting the blade angle. The preset angle can be the angle required for the blade to rotate forward, or other angles that are easy to calculate, so that the blade adjustment angle θ can be calculated later. At this time, based on the wind speed and rotation speed information, the blade adjustment command can also include setting the blade angle to the preset angle before generating the blade adjustment command. Thus, based on the wind speed and rotation speed information, the angle by which the blade needs to deviate from the preset angle can be determined, which can determine the blade adjustment angle θ, thereby improving the efficiency of determining the blade adjustment angle.

[0072] In one embodiment, after generating the fan blade adjustment command, the method further includes:

[0073] Based on the fan blade adjustment command, adjust the angle of the fan blade to the target angle indicated by the fan blade adjustment command;

[0074] Obtain the target rotation direction, which represents the rotation direction of the fan blades after the angle is adjusted to the target angle;

[0075] When the target rotation direction is reversed, a new fan blade adjustment command is generated based on wind speed and rotation speed information.

[0076] In this embodiment, after generating the blade adjustment command, the blade angle can be adjusted to the target angle indicated by the command. Even if the blade angle is adjusted, there may be situations where the wind speed is too high or the adjusted angle is too small, making it impossible to change the blade rotation direction from reverse to a non-reverse direction. In this case, it is necessary to obtain the target rotation direction after adjusting the blade angle to the target angle again. If the target rotation direction is a non-reverse direction, it means that the blade rotation direction is normal, and the main motor can be started to drive the blade rotation. However, if the target rotation direction is a reverse direction, it means that the blade rotation direction is abnormal. If the main motor is started to drive the blade rotation in this case, there will be a startup failure. In this case, a new blade adjustment command needs to be generated based on the wind speed and rotation speed information. The blade angle is adjusted again based on the new blade adjustment command. This process is repeated until the blade rotation direction is a non-reverse direction. This effectively counteracts the influence of the ambient wind on the blade and prevents startup failure caused by starting the blade in a reverse state.

[0077] S120: Control the fan blades to start when the rotation direction is not reversed.

[0078] In this embodiment, when it is determined that the rotation direction is not the reverse direction, the fan blades can be controlled to start. Specifically, the starting method can be to start the main motor of the fan device, and the operation of the main motor will start the fan blades to rotate.

[0079] In one embodiment, after the fan blades are started, the method further includes:

[0080] Acquire the second current signal, which represents the current value generated when the fan blades start rotating;

[0081] If the current value represented by the second current signal is greater than a preset threshold, a fault message is output.

[0082] If the current value represented by the second current signal is not greater than the preset threshold, adjust the angle of the fan blades to the preset angle.

[0083] In this embodiment, even if the preceding steps determine that the rotation direction is not reversed, there may still be environmental velocity components that accelerate the forward rotation speed of the fan blades. If the fan blade speed is too high, there will be operational abnormalities. Therefore, even after the fan blades start, a second current signal representing the current generated by the fan blades' rotation can be obtained. By judging whether the current value represented by the second current signal is greater than a preset threshold, if the current value represented by the second current signal is greater than the preset threshold, it indicates that the fan blade speed is too high, and a fault message can be output to remind the user or to pause the operation of the fan blades to protect the safety of the fan device. If the current value represented by the second current signal is not greater than the preset threshold, it indicates that the fan blade speed is within a safe range. Since the fan blades may have changed their angle through the preceding steps, and the fan blades need to be adjusted to a preset angle during startup to maximize heat exchange, the angle of the fan blades also needs to be adjusted to a preset angle after the fan blades start. The preset angle is the angle with the highest heat exchange efficiency of the fan blades.

[0084] For specific implementation details, please refer to... Figure 2 The current detection module continuously monitors the current value I and transmits it to the MCU to determine whether the three-phase current value I is greater than a preset current threshold. This embodiment uses U-phase current detection as an example. Specifically, Figure 2 In this circuit, the U terminal of current sensor U1 is connected to the U phase of the fan, and the Uout terminal is connected to the Uout output of the controller. Iu is the output current value of the current sensor. After voltage division by resistors R11 and R12 and filtering by capacitor C1, the current-voltage value is obtained as Uu = Iu × R12 / (R11 + R12). Uu is connected to the positive terminal of U2, and the negative terminal of U2 is connected to the output, forming a voltage follower. The output voltage of the voltage follower is also Uu. Uu is transmitted to the MCU through resistor R3. At this time, the MCU can calculate the current value I, I = |Uu / R3|. The current detection of the other two phases (V phase and W phase) can be obtained in the same way. If the current value I of any one or more phases is greater than the preset current threshold, a fault signal is issued and the machine stops. If the three-phase current value I is less than the preset current threshold, a fan blade start command is issued to start the fan blades. It can also be adjusted to the preset angle after a delay of t according to actual use needs.

The second rotating shaft 2 is used for transverse rotation under the drive of the adjustment module 3, thereby outputting rotational force to the rotating shaft rotation device 4. The rotating shaft rotation device 4 converts the transverse rotational force into longitudinal rotational force and outputs it to the first rotating shaft 1, thereby driving the first rotating shaft 1 to rotate longitudinally. The adjustment module 3 may include a fan blade rotation motor for outputting power to drive the second rotating shaft 2 to rotate, so that the fan blade rotation motor drives the second rotating shaft 2 to rotate laterally, and the rotating shaft rotation device 4 converts the transverse rotational force into longitudinal rotational force, driving the first rotating shaft 1 to rotate longitudinally, thereby adjusting the angle between the plane where the fan blades are located and the rotating shaft of the fan blades. It should be noted that the operating scenarios of the adjustment module 3 can be when the fan blades are reversed, when a power-on command is received, or when the fan blades are restored to a preset angle after forward rotation, etc., all of which can adjust the angle between the plane where the fan blades are located and the rotating shaft of the fan blades.
