[0040] For ease of understanding, the specific process in the embodiments of the present application is described below. Figure 1 , Figure 1A flow chart of an embodiment of a method for preventing a fan from freezing provided in an embodiment of the present application.

[0041] exist Figure 1 In the illustrated embodiment, the method specifically comprises the following steps:

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

[0043] It needs to be explained that the fan is an important component to maintain air circulation and temperature stability inside refrigeration equipment (such as air conditioners or refrigerators). In a low temperature environment, the humidity change around the fan is a key factor affecting the freezing of the fan. In a low temperature and high humidity environment, water vapor is more likely to condense into ice. Once the fan freezes, it will affect the operating efficiency of the fan and increase energy consumption, thereby affecting the performance and service life of the refrigeration equipment. Therefore, in this embodiment, the target humidity value of the fan is used as reference data for preventing and controlling the problem of fan freezing, 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 may 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: Compare 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 equipment or usage scenarios. It can be a factory setting or can be freely modified by the user according to actual usage, which is not limited here. 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 predicting whether the fan may freeze. In this embodiment, the collected target humidity value is compared with the preset maximum humidity threshold, and the comparison result is used to analyze whether the current working environment of the fan may cause the fan to freeze.

[0047] S103: If the target humidity value is greater than the maximum humidity threshold, the current operating parameters of the fan are adjusted to the target operating parameters according to a preset prevention and control strategy, so that the fan has a lower probability of freezing under the effect of the target operating parameters.

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

[0049] It should be explained that the prevention and control strategy refers to the information that guides the system to modify the current working parameters of the fan. The specific content needs to be set according to the type of working parameters, but in general, they are some countermeasures that can enable the fan to actively reduce the probability of icing. Specific examples will be given below.

[0050] In some embodiments, if the target humidity value is greater than the maximum humidity threshold, adjusting the current operating parameters of the fan to the target operating parameters according to a preset prevention and control strategy includes:

[0051] If the target humidity value is greater than the maximum humidity threshold, the current fan speed of the fan is increased to adjust the current fan speed to the 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 adjust the current fan speed to the 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 in the air on the blades can be effectively reduced, thereby reducing the risk of icing. Practice has shown that when the fan wind speed is greater than or equal to 4m / s, it is not easy to freeze; when the wind speed reaches more than 10m / s, the possibility of icing is basically zero. This is because higher wind speeds help speed up air flow, making it difficult for water vapor to stay on the blades and condense into ice.

[0053] In some embodiments, prevention and control measures can also be set in conjunction with a heating device installed on the fan blades, such as 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, increasing the current fan speed of the fan to adjust the current fan speed to the target fan speed includes:

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

[0056] In this embodiment, when the target humidity value exceeds the maximum humidity threshold and it is detected that the fan is currently in an unstarted state, the fan is started first, and the current fan speed of the fan is increased, and the current fan speed is adjusted to the first target fan speed, thereby reducing the probability of fan icing by increasing the fan speed.

[0057] In some embodiments, if the target humidity value is greater than the maximum humidity threshold, increasing the current fan speed of the fan to adjust the current fan speed to the target fan speed includes:

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

[0059] In this embodiment, when the target humidity value exceeds the maximum humidity threshold and it is detected that the fan is currently in the start-up state, the current fan speed of the fan is increased, and the current fan speed is adjusted to a second target fan speed whose speed is greater than the first target fan speed, so as to further increase the fan speed to achieve the purpose of reducing the probability of fan icing. It should be explained that, compared with the solution of not starting the fan, if the current target humidity value is still detected to exceed the maximum humidity threshold while the fan is started, it means that the current speed cannot achieve the effect of reducing the probability of fan icing, and the fan speed needs to be increased on the original basis to achieve the effect of reducing the probability of fan icing.

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

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

[0062] Obtaining a target humidity value collected by the fan in the working environment once every first preset time interval; or

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

[0064] In this embodiment, the target humidity value of the fan can be obtained in real time. This method can achieve real-time dynamic adjustment of the fan speed, but excessive adjustment of the fan speed may cause fan aging and affect the performance of the refrigeration equipment. The target humidity value of the fan can also be obtained at a scheduled time, for example, the target humidity value is obtained once every 10 seconds, which can avoid frequent adjustments to the fan speed due to short-term humidity fluctuations. The target humidity value of the fan can also be obtained by first obtaining multiple humidity values ​​collected by the fan in the working environment, and determining a reasonable target humidity value from the multiple humidity values ​​according to a preset data processing algorithm. Compared with the method of regular acquisition, it can avoid missing the humidity value corresponding to the critical moment.

[0065] In some embodiments, determining the target humidity value from the plurality of humidity values ​​according to a preset data processing algorithm includes:

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

[0067] In this embodiment, a plurality of humidity values ​​are smoothed, specifically, an average value of the plurality of humidity values ​​is calculated and the average value is used as the target humidity value, thereby reducing the influence of instantaneous fluctuations on the fan speed control.

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

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

[0070] In this embodiment, when it is detected that the target humidity value continues to exceed the set range, for example, for more than 10 minutes, it means that the fan may be in a low temperature and high humidity working environment for a long time, and the preset prevention and control strategy cannot play an effective prevention and control role. At this time, it is necessary to issue a fan abnormality prompt message 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 above optional technical solutions can be arbitrarily combined to form optional embodiments of the present application, which will not be described one by one here.

[0072] In specific implementation, the present application is not limited by the execution order of the various steps described. If no conflict occurs, some steps can be performed in other orders or simultaneously.

[0073] As can be seen from the above, the method for preventing the fan from freezing provided by the embodiment of the present application is to obtain the target humidity value collected in the working environment of the fan; compare the target humidity value with the preset maximum humidity threshold; if the target humidity value is greater than the maximum humidity threshold, adjust the current working parameters of the fan to the target working parameters according to the preset prevention and control strategy, so that the fan reduces the probability of freezing under the action of the target working parameters. By using the method for preventing the fan from freezing provided by the embodiment of the present application, by detecting the humidity change of the fan in the working environment and intelligently adjusting the working parameters of the fan according to the humidity change, the freezing phenomenon of the fan is effectively reduced, and the performance and service life of the equipment are improved.

Subsequently, the processor 180 provides corresponding visual output on the display panel 141 according to the type of touch event. Although in Figure 4 In the embodiment, the touch-sensitive surface 131 and the display panel 141 are implemented as two independent components to implement input and output functions.
