In order to improve the comfort of the indoor environment, air conditioners are usually installed in families to adjust the indoor environmental temperature. Generally, an air conditioner includes an indoor unit and an outdoor unit of the air conditioner. An indoor heat exchanger, a fan, etc. are provided in the indoor unit of the air conditioner; while a compressor, an outdoor heat exchanger, a refrigerant pipeline, an electric control circuit, etc. are installed in the outdoor unit of the air conditioner, and the outdoor unit of the air conditioner is installed outdoors during use, and the compressor, pipeline, etc. are more likely to fail due to the influence of the outdoor environment.

Among them, the wearable device can, for example, include: a smart watch, a smart bracelet, a pedometer, etc.

[0034] The embodiments of the present disclosure provide an air conditioner, which is configured with a rotation monitoring device for detecting the operating condition of the fan in the outdoor unit of the air conditioner. Optionally, the rotation monitoring device can obtain the cylindricity data of the fan so that the air conditioner can determine whether there is an abnormal rotation of the fan based on the obtained cylindricity data.

[0035] The fault warning method for an air conditioner provided by the embodiments of the present disclosure includes: obtaining the operation detection information of the fan by the rotation monitoring device; and generating a fault warning information when the operation detection information indicates that there is an abnormal rotation of the fan during operation.

[0036] Optionally, the execution subject of the above steps can be the control module of the air conditioner; specifically, the control module of the air conditioner obtains the operation detection information of the fan by the rotation monitoring device; the control module of the air conditioner generates a fault warning information when the operation detection information indicates that there is an abnormal rotation of the fan during operation. So that the air conditioner can push the fault warning information to the user, realizing the fault warning based on the fault of the fan in the outdoor unit of the air conditioner, effectively avoiding the safety hazards caused by the user not noticing the fault of the fan in the outdoor unit of the air conditioner, thereby improving the safety of the user using the air conditioner.

[0037] In the embodiments of the present disclosure, the fan in the outdoor unit of the air conditioner can be an axial flow fan. Taking the installed axial flow fan as an example in the embodiments of the outdoor unit of the air conditioner of the present disclosure, other types of fans can also be selected and set in other embodiments of the present application, which is not specifically limited here.

[0038] Based on the above related structural design of the air conditioner, the embodiments of the present disclosure provide a fault warning method for an air conditioner. As Figure 1 shown, the fault warning method for an air conditioner includes:

[0039] S01. Obtain the operation detection information of the fan by the rotation monitoring device;

[0040] S02. Generate a fault warning information when the operation detection information indicates that there is an abnormal rotation of the fan during operation.

[0041] Using the fault warning method for air conditioners provided by the embodiments of the present disclosure, the air conditioner is configured with a rotation monitoring device to monitor the operation of the fan of the outdoor unit of the air conditioner. When it is found that the fan has abnormal rotation, a fault warning message is generated in a timely manner, so that the air conditioner can prompt the user based on the fault warning message. In this way, the air conditioner can effectively capture whether the fan in the outdoor unit of the air conditioner has abnormal rotation, and generate a fault warning message in a timely manner when the abnormal rotation occurs, so that the air conditioner can prompt the user in a timely manner, realizing the fault warning based on the fault of the fan of the outdoor unit of the air conditioner, effectively avoiding the safety hazards caused by the fan in the outdoor unit of the air conditioner failing without the user noticing, thereby improving the safety of the user using the air conditioner.

[0042] Optionally, before obtaining the operation detection information of the fan by the rotation monitoring device, the fault warning method may further include: detecting whether the outdoor unit of the air conditioner is in a working state. Specifically, when the outdoor unit of the air conditioner is in a working state, the operation detection information of the fan by the rotation monitoring device is obtained. Since the outdoor unit of the air conditioner is in a working state, the installed fan will also be in an operating state, and the cylindricity data of the fan needs to be detected when the fan is in an operating state.

[0043] Optionally, the operation detection information of the fan includes the cylindricity data of the fan; the following method is used to determine whether there is abnormal rotation of the fan during operation: when the cylindricity data meets the abnormal rotation condition, it is determined that there is abnormal rotation of the fan during operation; when the cylindricity data does not meet the abnormal rotation condition, it is determined that there is no abnormal rotation of the fan during operation.

[0044] In this way, through the cylindricity data of the fan detected by the rotation monitoring device, it can be analyzed whether there is abnormal rotation of the fan during operation, so that the air conditioner can subsequently generate a fault warning message based on the abnormal rotation condition of the fan. Furthermore, it is convenient for the air conditioner to prompt the user based on the fault warning message, realizing the fault warning based on the fault of the fan of the outdoor unit of the air conditioner, effectively avoiding the safety hazards caused by the fan in the outdoor unit of the air conditioner failing without the user noticing, thereby improving the safety of the user using the air conditioner.

[0045] Optionally, the cylindricity data includes cylindricity values obtained continuously for multiple times; the following method is used to determine whether the cylindricity data meets the abnormal rotation condition: when multiple cylindricity values are all greater than a preset threshold, it is determined that the cylindricity data meets the abnormal rotation condition.

[0046] In this way, the judgment accuracy of whether the cylindricity data meets the rotation abnormality condition can be improved, so that the air conditioner generates a fault warning message that better conforms to the current abnormal fan rotation condition. Furthermore, the air conditioner can push this fault warning message to the user, realizing fault warning based on the fan fault of the outdoor unit of the air conditioner, effectively avoiding potential safety hazards caused by the fan failure in the outdoor unit of the air conditioner without the user's awareness, and thus improving the safety of users using the air conditioner.

[0047] Combined with Figure 2 As shown in the figure, another fault warning method for an air conditioner provided by an embodiment of the present disclosure includes:

[0048] S11. When multiple cylindricity values are all greater than a preset threshold, determine that the cylindricity data meets the rotation abnormality condition.

[0049] S12. Determine that there is an abnormal rotation during the operation of the fan.

[0050] By adopting the fault warning method for an air conditioner provided by an embodiment of the present disclosure, the air conditioner calculates and takes the average value of the cylindricity data detected multiple times, thereby improving the judgment accuracy of whether the cylindricity data meets the rotation abnormality condition, so that the air conditioner generates a fault warning message that better conforms to the current abnormal fan rotation condition. Furthermore, the air conditioner can push this fault warning message to the user, realizing fault warning based on the fan fault of the outdoor unit of the air conditioner, effectively avoiding potential safety hazards caused by the fan failure in the outdoor unit of the air conditioner without the user's awareness, and thus improving the safety of users using the air conditioner.

[0051] Optionally, the following method is used to determine whether the cylindricity data meets the rotation abnormality condition: obtain the specification information of the fan; determine the cylindricity reference threshold corresponding to the fan according to the specification information; when the cylindricity data is greater than the cylindricity reference threshold, determine that the cylindricity data meets the rotation abnormality condition.

[0052] Combined with Figure 3 As shown in the figure, another fault warning method for an air conditioner provided by an embodiment of the present disclosure includes:

[0053] S21. Obtain the specification information of the fan.

[0054] S22. Determine the cylindricity reference threshold corresponding to the fan according to the specification information.

[0055] S23. When the cylindricity data is greater than the cylindricity reference threshold, determine that the cylindricity data meets the rotation abnormality condition.

[0056] By using the fault warning method for an air conditioner provided in the embodiments of the present disclosure, the air conditioner determines the cylindricity reference threshold for determining whether the cylindricity data meets the abnormal rotation condition by adding the detection of the specification information of the fan, and adds the determinant of the specification information to the cylindricity reference threshold, so that the determined cylindricity reference threshold is more in line with the actual situation of the fan operation, thereby making the fault warning information determined by the air conditioner more in line with the operation state of the abnormal rotation of the fan. It can not only effectively improve the judgment accuracy of the air conditioner on whether the cylindricity data meets the abnormal rotation condition, so that the fault warning information generated by the air conditioner is more in line with the current abnormal rotation condition of the fan, and then enable the air conditioner to push the fault warning information to the user, realizing the fault warning based on the fan fault of the outdoor unit of the air conditioner, effectively avoiding the safety hazard caused by the user's failure to notice the fault of the fan in the outdoor unit of the air conditioner, and thus improving the safety of the user using the air conditioner.

[0057] Optionally, determining the cylindricity reference threshold corresponding to the fan according to the specification information includes: obtaining a fan information library, where the fan information library stores multiple specifications of the fan and the initial cylindricity measured during the test run at the factory for fans of different specifications; determining the initial cylindricity corresponding to the specification information from the fan information library; and determining the cylindricity reference threshold of the fan according to the initial cylindricity.

[0058] Combined with Figure 4 As shown, the embodiments of the present disclosure provide another fault warning method for an air conditioner, including:

[0059] S31. Obtain a fan information library, where the fan information library stores multiple specifications of the fan and the initial cylindricity measured during the test run at the factory for fans of different specifications.

[0060] S32. Determine the initial cylindricity corresponding to the specification information of the fan from the fan information library.

[0061] S33. Determine the cylindricity reference threshold of the fan according to the initial cylindricity.

[0062] By adopting the fault warning method for an air conditioner provided by the embodiments of the present disclosure, the air conditioner determines the cylindricity reference threshold for determining whether the cylindricity data meets the abnormal rotation condition by adding the detection of the specification information of the fan, so that the determined cylindricity reference threshold is more in line with the actual operation of the fan, thereby making the fault warning information determined by the air conditioner more in line with the abnormal rotation state of the fan. This can not only effectively improve the judgment accuracy of the air conditioner on whether the cylindricity data meets the abnormal rotation condition, enabling the air conditioner to generate fault warning information more in line with the current abnormal rotation condition of the fan, and further enabling the air conditioner to push the fault warning information to the user, realizing the fault warning based on the fan fault of the outdoor unit of the air conditioner, effectively avoiding the safety hazards caused by the user's unawareness of the fan fault in the outdoor unit of the air conditioner, and thus improving the safety of the user using the air conditioner.

[0063] In some embodiments, generating the fault warning information specifically includes: determining the fault type of the fan; determining the abnormal troubleshooting strategy for the fan according to the fault type; and determining the fault warning information based on the abnormal troubleshooting strategy. Optionally, determining the abnormal troubleshooting strategy for the fan according to the fault type may include: obtaining a fault information library that stores various fault types of the fan and the first corresponding relationship between the fault type and the abnormal troubleshooting strategy; and determining the abnormal troubleshooting strategy corresponding to the fault type of the fan according to the first corresponding relationship in the fault information library.

[0064] Optionally, determining the fault type of the fan includes: determining the fault type of the fan according to the cylindricity data of the fan. Specifically, determining the fault type of the fan according to the cylindricity data of the fan may include: determining the monitoring waveform of the cylindricity data; analyzing the monitoring waveform of the cylindricity data to obtain the characteristic information of the cylindricity data; and determining the fault type of the fan according to the characteristic information of the cylindricity data.

[0065] Further, determining the fault type of the fan according to the characteristic information of the cylindricity data and determining the abnormal troubleshooting strategy for the fan based on the fault type includes: when the characteristic information indicates that the fan rotates unevenly, determining the abnormal troubleshooting strategy for the fan as checking whether there is dirt blockage in the fan; when the characteristic information indicates that the fan rotates unevenly, determining the abnormal troubleshooting strategy for the fan as adding lubricant to the motor of the fan; when the characteristic information indicates that the fan rotates discontinuously, determining the abnormal troubleshooting strategy for the fan as replacing the motor coil of the fan.

[0066] Optionally, determining the fault warning information based on the abnormal troubleshooting strategy may include: obtaining a fault information library that stores the second corresponding relationship between the abnormal troubleshooting strategy and the fault warning information; and determining the fault warning information corresponding to the abnormal troubleshooting strategy according to the second corresponding relationship in the fault information library.

[0067] In this way, the air conditioner detects the cylindricity data of the fan, determines the fault type of the fan based on the cylindricity data of the fan, then determines the abnormal troubleshooting strategy for the fan based on the fault type, and then determines the fault warning information based on the abnormal troubleshooting strategy, so that the air conditioner reminds the user to perform fault troubleshooting based on the determined abnormal troubleshooting strategy; thereby realizing the effective capture of whether the fan in the outdoor unit of the air conditioner rotates abnormally, and generating a corresponding abnormal troubleshooting strategy in time when the rotation abnormality occurs, so that the user can select a response method with reference to the abnormal troubleshooting strategy.

[0068] Optionally, when it is determined that the fan has a rotation abnormality during operation, the fault warning method further includes: controlling the air conditioner to stop running and maintaining a preset interval duration; controlling the fan to reverse and re-acquiring the cylindricity data of the fan; when the re-acquired cylindricity data still meets the rotation abnormality condition, generating a fault warning information.

[0069] Optionally, after controlling the air conditioner to stop running and maintaining a preset interval duration, the fault warning method may further include: controlling the fan to restart and run, and re-acquiring the cylindricity data of the fan; after acquisition, controlling the air conditioner to stop running again and maintaining a preset interval duration, and repeating this multiple times. And calculate the average value of the cylindricity data obtained multiple times to obtain the cylindricity data for abnormal troubleshooting. And when the cylindricity data meets the rotation abnormality condition, generating a fault warning information.

[0070] In the embodiments of the present disclosure, the preset interval duration is used to represent the interval duration for controlling the air conditioner to stop running and wait. Here, the preset interval duration can be preset at the factory or manually set by the air conditioner installation or maintenance personnel. Specifically, the preset interval duration can be selected within the range of 8 - 12 minutes. For example, the preset interval duration can be 10 minutes.

[0071] Combined with Figure 5 As shown, the embodiments of the present disclosure provide another fault warning method for an air conditioner, including:

[0072] S41. When it is determined that the fan has a rotation abnormality during operation, control the air conditioner to stop running and maintain a preset interval duration.

[0073] S42. Control the fan to reverse and re-acquire the cylindricity data of the fan.

[0074] S43. When the re-acquired cylindricity data still meets the rotation abnormality condition, generate a fault warning information.

[0075] By adopting the fault warning method for an air conditioner provided by the embodiments of the present disclosure, when the air conditioner determines that the cylindricity data meets the abnormal rotation condition, it adds abnormal verification operations for the reverse rotation or average value calculation of the fan, and when it determines again that the fan has abnormal rotation, it generates a fault warning message, so that the fault warning message more conforms to the actual situation of the fan operation. When the air conditioner prompts the user based on such a fault warning message, it can effectively capture whether the fan in the outdoor unit of the air conditioner has abnormal rotation, and generate a fault warning message in time when abnormal rotation occurs, so that the air conditioner can prompt the user in time, realize fault warning based on the fan fault in the outdoor unit of the air conditioner, and effectively avoid potential safety hazards caused by the user's unawareness of the fan fault in the outdoor unit of the air conditioner, thereby improving the safety of the user using the air conditioner.

[0076] In some embodiments, after generating the fault warning message, the fault warning method further includes: controlling the display module of the air conditioner to display the fault code corresponding to the fault warning message; or, controlling the voice module of the air conditioner to issue a voice prompt including the fault warning message.

[0077] In this way, by reminding the user of the generated fault information by displaying the fault code or issuing a voice prompt, the user can timely learn that the fan in the outdoor unit of the air conditioner has a fault, thereby avoiding potential safety hazards such as refrigerant leakage and damage to the electronic control circuit caused by the continued operation of the faulty fan. The air conditioner effectively solves the problem that it is difficult for the user to detect the fault of the fan in the outdoor unit of the air conditioner by executing the above control method, and further effectively improves the safety of the user using the air conditioner.

[0078] Combined Figure 6 As shown, the embodiments of the present disclosure provide a fault warning device for an air conditioner, including a processor 100 and a memory 101. Optionally, the device may further include a communication interface 102 and a bus 103.
