[0040] For ease of understanding, the specific processes in the embodiments of the present application are described below. Please refer to Figure 1 , Figure 1An embodiment flowchart of a method for preventing icing of a fan is provided in the embodiments of the present application.

[0041] In Figure 1 In the embodiment shown, the method specifically includes the following steps:

[0042] S101, obtaining a target humidity value collected in a working environment of a fan.

[0043] It should be explained that the fan is an important component for maintaining air circulation and temperature stability inside a refrigeration device (e.g., an air conditioner or a refrigerator). In a low-temperature environment, humidity changes around the fan are a key factor affecting icing of the fan. In an environment with low temperature and high humidity, water vapor is more likely to condense into ice. Once the fan ices, the operating efficiency of the fan will be affected and energy consumption will be increased, thereby affecting the performance and service life of the refrigeration device. Therefore, in the embodiments, the target humidity value of the fan is used as reference data for preventing and controlling icing of the fan, and the target humidity value needs to be collected in the working environment of the fan to increase the objectivity and effectiveness of the reference data.

[0044] In some embodiments, the target humidity value can be obtained by installing a humidity sensor at the location of the fan, and using the humidity sensor to collect the target humidity value of the fan in the working environment.

[0045] S102, comparing the target humidity value with a preset maximum humidity threshold.

[0046] It should be explained that the maximum humidity threshold can be set according to different refrigeration devices or use scenarios, and can be factory-set or freely modified by users according to actual use, which is not limited herein. The maximum humidity threshold is only used as a basis for determining whether the target humidity value currently collected by the fan is abnormal and whether the fan is likely to ice. In the embodiments, the collected target humidity value is compared with the preset maximum humidity threshold, and whether the working environment of the fan is likely to cause icing of the fan is analyzed according to the comparison result.

[0047] S103, if the target humidity value is greater than the maximum humidity threshold, adjusting a current working operating parameter of the fan to a target working operating parameter according to a preset prevention and control strategy, so as to reduce the icing probability of the fan under the action of the target working operating parameter.

[0048] In this embodiment, when the current target humidity value collected by the fan exceeds the preset maximum humidity threshold, it indicates that the current target humidity value is abnormal, which means that the fan may freeze in the current working environment. At this time, the current working parameter of the fan is adjusted to the target working parameter according to the preset prevention and control strategy, so as to reduce the icing probability of the fan under the action of the target working parameter.

[0049] It should be explained that the prevention and control strategy refers to the information guiding the system to modify the current working parameter of the fan, and the specific content needs to be set according to the type of the working parameter, but in general, it is some measures that can make the fan actively reduce the icing probability, which will be illustrated by examples in the following.

[0050] In some embodiments, if the target humidity value is greater than the maximum humidity threshold, the current working parameter of the fan is adjusted to the target working parameter according to the preset prevention and control strategy, including:

[0051] If the target humidity value is greater than the maximum humidity threshold, the current fan speed of the fan is increased, and the current fan speed is adjusted to a target fan speed.

[0052] In this embodiment, the prevention and control strategy is set to actively increase the current fan speed of the fan, and the current fan speed is adjusted to a target fan speed. By increasing the wind speed, the deposition of water vapor in the air on the fan blades can be reduced, thereby reducing the risk of icing. Specifically, when the wind speed reaches a certain value, the deposition of water vapor on the blades can be effectively reduced, thereby reducing the risk of icing. Practice shows that when the fan speed is greater than or equal to 4 m / s, icing is not easy; when the wind speed reaches 10 m / s or more, the possibility of icing is basically zero. This is because a higher wind speed helps to speed up air flow, making it difficult for water vapor to stay on the blades and condense into ice.

[0053] In some embodiments, the prevention and control measures can also be set in combination with the heating device installed on the fan blades, for example, actively turning on the heating device to heat the surface of the fan blades, thereby reducing the deposition of water vapor in the air on the fan blades, thereby reducing the risk of icing.

[0054] In some embodiments, if the target humidity value is greater than the maximum humidity threshold, the current fan speed of the fan is increased, and the current fan speed is adjusted to a target fan speed, including:

[0055] If the target humidity value is greater than the maximum humidity threshold, and the fan is not currently started, the fan is started, and the current fan speed of the fan is increased, and the current fan speed is adjusted to a first target fan speed.

[0056] In the embodiment, when the target humidity value exceeds the maximum humidity threshold value and it is detected that the fan is currently in the non-started state, the fan is first started, and the current fan rotating speed of the fan is increased, the current fan rotating speed is adjusted to the first target fan rotating speed, and the fan speed is increased to reduce the probability of fan icing.

[0057] In some embodiments, if the target humidity value is greater than the maximum humidity threshold value, the current fan rotating speed of the fan is increased, and the current fan rotating speed is adjusted to a target fan rotating speed, including:

[0058] If the target humidity value is greater than the maximum humidity threshold value, and the fan has been started, the current fan rotating speed of the fan is increased, and the current fan rotating speed is adjusted to a second target fan rotating speed, wherein the second target fan rotating speed is greater than the first target fan rotating speed.

[0059] In the embodiment, when the target humidity value exceeds the maximum humidity threshold value, and it is detected that the fan is currently in the started state, the current fan rotating speed of the fan is increased, the current fan rotating speed is adjusted to a second target fan rotating speed which is greater than the first target fan rotating speed, and the fan speed is further increased to reduce the probability of fan icing. It should be explained that, compared with the scheme of non-started fan, if the current target humidity value exceeds the maximum humidity threshold value while the fan is started, it indicates that the current rotating speed cannot reduce the probability of fan icing, and the fan rotating speed needs to be increased on the basis of the original rotating speed to reduce the probability of fan icing.

[0060] In some embodiments, the target humidity value collected in the working environment of the fan includes:

[0061] The target humidity value collected in the working environment of the fan is acquired in real time; or

[0062] The target humidity value collected in the working environment of the fan is acquired every first preset time interval; or

[0063] A plurality of humidity values collected in the working environment of the fan are acquired, and the target humidity value is determined from the plurality of humidity values according to a preset data processing algorithm.

[0064] In the embodiment, the target humidity value of the fan can be acquired in real time, which can realize real-time dynamic adjustment of the fan speed. However, excessive adjustment of the fan speed can cause aging of the fan and affect the performance of the refrigeration equipment. The target humidity value of the fan can also be acquired at a fixed time, for example, the target humidity value is acquired once every 10 seconds, which can avoid frequent adjustment of the fan speed due to short-time humidity fluctuation. The target humidity value of the fan can also be acquired by first acquiring a plurality of humidity values collected by the fan in the working environment, and determining a reasonable target humidity value from the plurality of humidity values according to a preset data processing algorithm. Compared with the fixed-time acquisition mode, the method can also avoid missing the humidity value at a critical moment.

[0065] In some embodiments, the target humidity value is determined from the plurality of humidity values according to a preset data processing algorithm, including:

[0066] The plurality of humidity values are smoothed, an average value of the plurality of humidity values is calculated, and the average value is taken as the target humidity value.

[0067] In the embodiment, the plurality of humidity values are smoothed, and specifically, an average value of the plurality of humidity values is calculated, and the average value is taken as the target humidity value, to reduce the influence of instantaneous fluctuation on the fan speed control.

[0068] In some embodiments, after the target humidity value collected in the working environment of the fan is acquired, the method further includes:

[0069] When the target humidity value exceeds the maximum humidity threshold and the duration exceeds the second preset duration, a fan abnormality prompt information is issued.

[0070] In the embodiment, when it is detected that the target humidity value continuously exceeds the set range, for example, for more than 10 minutes, it is indicated that the fan can be in a low-temperature and high-humidity working environment for a long time, and the preset prevention and control strategy cannot effectively prevent and control. At this time, the fan abnormality prompt information needs to be issued to prompt the user to check the equipment in time, to avoid affecting the normal operation of the fan and the equipment.

[0071] All the optional technical solutions described above can be combined to form optional embodiments of the present application, which will not be described again.

[0072] In specific implementation, the present application is not limited by the execution order of the various steps, and some steps can also be performed in other order or simultaneously without conflict.

[0073] As can be seen, the method for preventing the fan from icing provided by the embodiment of the present application obtains a target humidity value collected in the working environment of the fan; compares the target humidity value with a preset maximum humidity threshold; if the target humidity value is greater than the maximum humidity threshold, adjusts the current working operation parameter of the fan to a target working operation parameter according to a preset prevention and control strategy, so as to reduce the icing probability of the fan under the action of the target working operation parameter. By using the method for preventing the fan from icing provided by the embodiment of the present application, the humidity change of the fan in the working environment is detected, and the working operation parameter of the fan is intelligently adjusted according to the humidity change, so as to effectively reduce the icing phenomenon of the fan and improve the performance and service life of the equipment.

Optionally, the touch-sensitive surface 131 may include two parts: a touch detection device and a touch controller. The touch detection device detects the user's touch position and the signal generated by the touch operation, and transmits the signal to the touch controller; the touch controller receives touch information from the touch detection device, converts it into touch point coordinates, sends it to the processor 180, and can receive and execute commands from the processor 180. In addition, the touch-sensitive surface 131 can be implemented using various types such as resistive, capacitive, infrared, and surface acoustic wave. Besides the touch-sensitive surface 131, the input unit 130 may also include other input electronic devices 132. Specifically, other input electronic devices 132 may include, but are not limited to, one or more of the following: a physical keyboard, function keys (such as volume control buttons, power buttons, etc.), a trackball, a mouse, and a joystick.

[0107] Display unit 140 can be used to display information input by the user or information provided to the user, as well as various graphical user interfaces of electronic device 1200.

Display unit 140 may include display panel 141, optionally configured as LCD (Liquid Crystal Display), OLED (Organic Light-Emitting Diode), etc. Further, touch-sensitive surface 131 may cover display panel 141. When touch-sensitive surface 131 detects a touch operation on or near it, it transmits the information to processor 180 to determine the type of touch event. Subsequently, processor 180 provides corresponding visual output on display panel 141 according to the type of touch event. Although in Figure 4 In this embodiment, the touch-sensitive surface 131 and the display panel 141 are implemented as two separate components to realize input and output functions.

As a type of motion sensor, a gravity acceleration sensor can detect the magnitude of acceleration in various directions (generally three axes). When stationary, it can detect the magnitude and direction of gravity and can be used for applications that recognize the phone's posture (such as landscape / portrait switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc. Other sensors that may be configured in the electronic device 1200, such as gyroscopes, barometers, hygrometers, thermometers, and infrared sensors, will not be described in detail here.

[0109] Audio circuitry 160, speaker 161, and microphone 162 provide an audio interface between the user and electronic device 1200. Audio circuitry 160 converts received audio data into electrical signals and transmits them to speaker 161, where speaker 161 converts them into sound signals for output. Conversely, microphone 162 converts collected sound signals into electrical signals, which are then received by audio circuitry 160, converted back into audio data, and processed by processor 180. The audio data is then transmitted via RF circuitry 110 to another terminal, or output to memory 120 for further processing. Audio circuitry 160 may also include an earphone jack to facilitate communication between external headphones and electronic device 1200.
