[0035] The embodiments of the present disclosure provide an air conditioner. The indoor unit of the air conditioner is configured with a rotation monitoring device, and the rotation monitoring device is used to detect the operating condition of the blower in the indoor unit. Optionally, the rotation monitoring device can obtain the cylindricity data of the blower, so that the air conditioner can determine whether there is an abnormal rotation of the blower based on the obtained cylindricity data.

[0036] The fault detection method for an air conditioner provided by the embodiments of the present disclosure includes: when the indoor unit of the air conditioner is in a working state, obtaining the cylindricity data of the target blower in the indoor unit; when the cylindricity data meets the abnormal rotation condition, determining an abnormal troubleshooting strategy for the target blower.

[0037] 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 cylindricity data of the target blower in the indoor unit when the indoor unit of the air conditioner is in a working state; the control module of the air conditioner determines an abnormal troubleshooting strategy for the target blower when the cylindricity data meets the abnormal rotation condition. So that the air conditioner can execute the abnormal troubleshooting strategy to determine the fault type of the target blower. Or, the air conditioner reminds the user to perform fault troubleshooting based on the determined abnormal troubleshooting strategy.

[0038] In the embodiments of the present disclosure, the target blower is the blower in the indoor unit of the air conditioner. Specifically, the blower in the indoor unit can be a cross-flow blower. Exemplarily, taking the cross-flow blower installed in the indoor unit of the air conditioner in the embodiments of the present disclosure as an example, other types of blowers can also be selected as the target blower in other embodiments of the present application.

[0039] Based on the above related structural design of the air conditioner, the embodiments of the present disclosure provide a fault detection method for an air conditioner. As Figure 1 shown, the fault detection method for an air conditioner includes:

[0040] S01. When the indoor unit of the air conditioner is in a working state, obtain the cylindricity data of the target blower in the indoor unit.

[0041] S02. When the cylindricity data meets the abnormal rotation condition, determine an abnormal troubleshooting strategy for the target blower.

[0042] Using the fault detection method for air conditioners provided by the embodiments of the present disclosure, the air conditioner detects the cylindricity data of the target fan while its indoor unit is in the working state, and then determines whether there is an abnormal rotation of the target fan according to the cylindricity data of the target fan, and timely determines an abnormal troubleshooting strategy for the target fan in the case of abnormal rotation of the target fan. To effectively capture whether there is an abnormal rotation of the fan in the indoor unit of the air conditioner, and timely generate a corresponding abnormal troubleshooting strategy when an abnormal rotation occurs, so that the user can refer to the abnormal troubleshooting strategy to select a response method. In this way, even when the user hears an operating noise in the air conditioner, there is no need to judge whether the fan fails based on their own experience, which improves the convenience of the user using the air conditioner and reduces the user's experience requirements for using the air conditioner.

[0043] In practical applications, since the indoor unit of the air conditioner is in the working state, the target fan in the indoor unit will be in the operating state. The cylindricity data of the target fan needs to be detected when the target fan is in the operating state.

[0044] Optionally, determining the abnormal troubleshooting strategy for the target fan includes: determining the fault type of the target fan; based on the fault type, determining the abnormal troubleshooting strategy for the target fan. Specifically, based on the fault type, determining the abnormal troubleshooting strategy for the target fan may include: obtaining a fault information library, which stores various fault types of the fan and the corresponding relationship between the fault type and the abnormal troubleshooting strategy; according to the corresponding relationship in the fault information library, determining the abnormal troubleshooting strategy corresponding to the fault type of the target fan.

[0045] Optionally, determining the fault type of the target fan includes: determining the fault type of the target fan according to the cylindricity data of the target fan. Specifically, according to the cylindricity data of the target fan, determining the fault type of the target 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; according to the characteristic information of the cylindricity data, determining the fault type of the target fan.

[0046] Furthermore, according to the characteristic information of the cylindricity data, determining the fault type of the target fan, and based on the fault type, determining the abnormal troubleshooting strategy for the target fan includes: in the case where the characteristic information indicates uneven rotation of the fan, determining the abnormal troubleshooting strategy for the target fan as checking whether there is a blockage; in the case where the characteristic information indicates uneven rotation of the fan, determining the abnormal troubleshooting strategy for the target fan as adding lubricant to the motor of the fan; in the case where the characteristic information indicates discontinuous rotation of the fan, determining the abnormal troubleshooting strategy for the target fan as replacing the motor coil of the fan.

[0047] Combined with Figure 2As shown, an embodiment of the present disclosure provides another fault detection method for an air conditioner, including:

[0048] S11. Determine the fault type of the target fan.

[0049] S12. Based on the fault type, determine the abnormal troubleshooting strategy for the target fan.

[0050] By using the fault detection method for an air conditioner provided by the embodiment of the present disclosure, the air conditioner detects the cylindricity data of the target fan, then determines the fault type of the target fan according to the cylindricity data of the target fan, and further determines the abnormal troubleshooting strategy for the target fan based on the fault type, so that the air conditioner reminds the user to perform fault troubleshooting based on the determined abnormal troubleshooting strategy; thus, the air conditioner can effectively capture whether the fan in the indoor unit rotates abnormally, and generate a corresponding abnormal troubleshooting strategy in time when a rotation abnormality occurs, so that the user can select a response method with reference to the abnormal troubleshooting strategy.

[0051] In some embodiments, before determining the abnormal troubleshooting strategy for the target fan, the fault detection method for the air conditioner further includes: controlling the air conditioner to stop running and maintaining a preset interval duration; performing an abnormal verification operation on the target fan to obtain an abnormal verification result; and determining the abnormal troubleshooting strategy for the target fan when the abnormal verification result indicates that the target fan has a rotation abnormality.

[0052] In the embodiment 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 installer 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.

[0053] Optionally, performing an abnormal verification operation on the target fan may include: controlling the target fan to restart and run, and re-acquiring the cylindricity data of the target fan; after acquisition, controlling the air conditioner to stop running again and maintaining the 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.

[0054] Combined Figure 3 As shown, an embodiment of the present disclosure provides another fault detection method for an air conditioner, including:

[0055] S21. Control the air conditioner to stop running and maintain a preset interval duration.

[0056] S22. Perform an abnormal verification operation on the target fan to obtain an abnormal verification result.

[0057] S23. When the abnormal verification result indicates that there is an abnormal rotation of the target fan, further determine the abnormal troubleshooting strategy for the target fan.

[0058] By using the fault detection method for air conditioners provided in the embodiments of the present disclosure, when it is determined that the cylindricity data meets the conditions of abnormal rotation, an abnormal verification operation for the target fan is added. When the abnormal verification result also indicates that there is an abnormal rotation of the target fan, further determine the abnormal troubleshooting strategy for the target fan. In this way, the cylindricity data used to determine the abnormal troubleshooting strategy can be made more accurate, so that the abnormal troubleshooting strategy determined by the air conditioner is more in line with the current fault cause of the abnormal rotation of the target fan. Furthermore, the air conditioner reminds the user to perform fault troubleshooting based on the determined abnormal troubleshooting strategy; to effectively capture whether there is an abnormal rotation of the fan in the indoor unit of the air conditioner, and generate a corresponding abnormal troubleshooting strategy in a timely manner when an abnormal rotation occurs, so that the user can select a response method with reference to the abnormal troubleshooting strategy.

[0059] Optionally, performing an abnormal verification operation on the target fan includes: controlling the target fan to rotate in reverse, and re-acquiring the cylindricity data of the target fan; when the re-acquired cylindricity data meets the conditions of abnormal rotation, determining that the abnormal verification result is that there is an abnormal rotation of the target fan; when the re-acquired cylindricity data does not meet the conditions of abnormal rotation, controlling the air conditioner to restart and run.

[0060] In this way, when it is determined that the cylindricity data meets the conditions of abnormal rotation, an abnormal verification operation for the target fan is added. When the abnormal verification result also indicates that there is an abnormal rotation of the target fan, further determine the abnormal troubleshooting strategy for the target fan. In this way, the cylindricity data used to determine the abnormal troubleshooting strategy can be made more accurate, so that the abnormal troubleshooting strategy determined by the air conditioner is more in line with the current fault cause of the abnormal rotation of the target fan. Furthermore, the air conditioner reminds the user to perform fault troubleshooting based on the determined abnormal troubleshooting strategy; to effectively capture whether there is an abnormal rotation of the fan in the indoor unit of the air conditioner, and generate a corresponding abnormal troubleshooting strategy in a timely manner when an abnormal rotation occurs, so that the user can select a response method with reference to the abnormal troubleshooting strategy.

[0061] 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 conditions of abnormal rotation: when multiple cylindricity values are all greater than a preset threshold, it is determined that the cylindricity data meets the conditions of abnormal rotation.

[0062] In this way, it is possible to improve the judgment accuracy of whether the cylindricity data meets the abnormal rotation condition, so that the abnormal troubleshooting strategy determined by the air conditioner better conforms to the fault cause of the current abnormal rotation of the target fan. Furthermore, the air conditioner can remind the user to perform fault troubleshooting based on the determined abnormal troubleshooting strategy; to effectively capture whether the fan in the indoor unit of the air conditioner has abnormal rotation, and generate a corresponding abnormal troubleshooting strategy in a timely manner when abnormal rotation occurs, so that the user can select a response method with reference to the abnormal troubleshooting strategy.

[0063] Optionally, the following method is used to determine whether the cylindricity data meets the abnormal rotation condition: obtain the specification information of the target fan; determine the cylindricity reference threshold corresponding to the target fan according to the specification information; and determine that the cylindricity data meets the abnormal rotation condition when the cylindricity data is greater than the cylindricity reference threshold.

[0064] Combined with Figure 4 As shown in

[0065] S31. Obtain the specification information of the target fan.

[0066] S32. Determine the cylindricity reference threshold corresponding to the target fan according to the specification information.

[0067] S33. Determine that the cylindricity data meets the abnormal rotation condition when the cylindricity data is greater than the cylindricity reference threshold.

[0068] By using the fault detection method for the air conditioner provided by the embodiments of the present disclosure, by adding the detection of the specification information of the target fan, the cylindricity reference threshold for determining whether the cylindricity data meets the abnormal rotation condition includes the determinant of the specification information, so that the determined cylindricity reference threshold better conforms to the actual situation of the target fan, and thus the abnormal troubleshooting strategy determined by the air conditioner better conforms to the fault cause of the current abnormal rotation of the target fan.

[0069] Optionally, determining the cylindricity reference threshold corresponding to the target fan according to the specification information includes: obtaining a fan information library, which stores multiple specifications of the fan and the initial cylindricity measured during the test run at the factory for different specifications of the fan; determining the initial cylindricity corresponding to the specification information of the target fan from the fan information library; and determining the cylindricity reference threshold of the target fan according to the initial cylindricity.

[0070] Combined with Figure 5 As shown in

[0071] S41. Obtain a fan information library, which stores multiple specifications of the fan and the initial cylindricity measured during the test run at the factory for different specifications of the fan.

[0072] S42. Determine the initial cylindricity corresponding to the specification information of the target fan from the fan information library.

[0073] S43. Determine the cylindricity reference threshold of the target fan according to the initial cylindricity.

[0074] By using the fault detection method for air conditioners provided in the embodiments of the present disclosure, by adding the detection of the specification information of the target fan, the cylindricity reference threshold for determining whether the cylindricity data meets the abnormal rotation condition is increased by the determinant of the specification information, so that the determined cylindricity reference threshold is more in line with the actual situation of the target fan, thereby making the abnormal troubleshooting strategy determined by the air conditioner more in line with the current fault cause of the abnormal rotation of the target fan.
