[0052] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0053] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0054] like Figures 1 to 5 As shown, an exemplary embodiment of the present invention provides an air conditioner, which includes an indoor unit 1. The indoor unit 1 includes a frame 11 and a fan assembly 12 disposed within the frame 11. The fan assembly 12 may include a fan and a motor that drives the fan to rotate, and the fan may include, but is not limited to, an axial flow fan. The fan assembly 12 is connected to the frame 11 via a rotating assembly 13.

[0055] Reference Figure 1 and combined Figures 2 to 5As shown, the rotating assembly 13 includes a bearing housing 131 and a rotating shaft 132. The bearing housing 131 may be mounted on one of the vertical plates 111 within the frame 11. One end of the rotating shaft 132 is inserted into a bearing hole (not shown) in the bearing housing 131, and this end of the rotating shaft 132 and the bearing hole have a hole-shaft mating relationship. The other end of the rotating shaft 132 passes through the fan assembly 12. Specifically, this end of the rotating shaft 132 passes through the fan and is connected to the output end of the motor, so that it rotates under the drive of the motor, thereby driving the fan to rotate along the central axis of the rotating shaft 132.

[0056] The air conditioner also includes a position sensor (not shown in the figure) for detecting distance. The position sensor is used to detect the position of different points on the rotating shaft 132 after a predetermined running time, and then obtain the distance difference between the different position points through the above position.

[0057] Furthermore, the air conditioner also includes a length sensor (not shown in the figure) that uses a stylus method to obtain the surface roughness of the bearing bore. This length sensor can be an electrical type. Of course, in this example, the air conditioner may also include sensors or inspection instruments that utilize other methods for obtaining surface roughness, and the specific type of sensor or inspection instrument is not specifically limited here.

[0058] It should be noted that since the rotating shaft 132 is directly inserted into the bearing hole of the bearing housing 131, the inner surface of the bearing hole may wear during long-term operation of the air conditioner, or wear may occur on both the inner surfaces of the rotating shaft 132 and the bearing hole. After wear occurs, the fan may no longer rotate along the central axis of the rotating shaft 132, and the fan may rotate eccentrically or vibrate abnormally. In severe cases, this may damage the fan and even other internal components of the indoor unit 1, reducing the user experience of the air conditioner.

[0059] In order to enable users to detect the wear condition of the inner surface of the bearing hole in the bearing housing 131 or the rotating shaft 132 in the air conditioner in the first instance, and to carry out after-sales repair or replacement of the bearing housing 131 or the rotating shaft 132 in a timely manner, thereby improving the service life and user experience of the air conditioner, the present invention also provides an air conditioner control method.

[0060] like Figure 5 As shown, an exemplary embodiment of the present invention provides an air conditioning control method, which includes the following steps:

[0061] S100: Obtain the roughness difference of the rotating component and at least two position points after running for a predetermined time.

[0062] S200: Based on the relationship between the roughness difference and the first preset threshold, and based on the relationship between the distance difference between at least two position points and the second preset threshold, the rotating component is processed.

[0063] In step S100, after the air conditioner is installed and has been running for a predetermined period of time, the rotating component 13 in the air conditioner may experience wear, causing the fan assembly 12 to malfunction. The predetermined period can be flexibly set based on experimental or empirical values; for example, the predetermined period can be an integer multiple of one month, and the specific value of the predetermined period is not specifically limited here.

[0064] Therefore, in order to obtain the operating status of the rotating assembly 13 in the air conditioner in a timely manner, after a predetermined time, the surface roughness value of some components in the rotating assembly 13 is obtained using a length sensor. In this example and the following embodiments, the rotating assembly 13 is described as including a bearing housing 131 and a rotating shaft 132. The rotating shaft 132 is in contact with the bearing hole 1311 in the bearing housing 131. Based on this, the roughness value of the inner surface of the bearing hole 1311 in the rotating assembly 13 can be obtained using a length sensor. Alternatively, other detection methods can be used to detect the roughness value of the inner surface of the bearing hole.

[0065] The roughness difference value in this step is used to characterize the difference between the initial roughness value of the bearing bore's inner surface and the roughness value of the bearing bore's inner surface after a predetermined period of use. The initial roughness value of the bearing bore's inner surface can be tested and recorded at the factory after the bearing bore is machined and manufactured.

[0066] After obtaining the roughness difference value, at least two position points in the rotating assembly 13 are obtained using a position sensor. Specifically, at least two position points on the rotation shaft 132 in the rotating assembly 13 can be obtained using a position sensor. The distance difference between the at least two position points is used to characterize the difference in the vertical distance between the at least two position points, or the distance difference between the at least two position points can also be used to characterize the difference in the distance between the position of each position point and the central axis L of the rotation shaft 132.

[0067] Reference Figure 7 As shown, in step S200, the relationship between the roughness difference and the first preset threshold P1 includes the following two types:

[0068] Firstly, when the roughness difference is less than or equal to the first preset threshold P1, it indicates that the wear of the inner surface of the bearing hole 1311 in the bearing housing 131 and / or the wear of the rotating shaft 132 are within the allowable wear range. At this time, the wear will not have a significant impact on the rotation of the fan, and the air conditioner can continue to be used.

[0069] The second scenario is that when the roughness difference is greater than the first preset threshold P1, it indicates that the wear of the inner surface of the bearing hole 1311 in the bearing housing 131 and / or the wear of the rotating shaft 132 may be quite severe, which may have a significant impact on the rotation of the fan.

[0070] The value of the first preset threshold P1 can be set by those skilled in the art based on experiments or experience in practical applications, and the value or range of the first preset threshold P1 is not specifically limited here.

[0071] Therefore, when the roughness difference is greater than the first preset threshold P1, a logical judgment is made based on the relationship between the distance difference between at least two location points and the second preset threshold P2. The value of the second preset threshold P2 can also be set by those skilled in the art based on experiments or experience in practical applications, and the value or range of the second preset threshold P2 is not specifically limited here. It should be noted that in this example, the number of location points can be two, three, four, or more.

[0072] In the logical judgment based on the relationship between the distance difference between at least two locations and the second preset threshold P2, when the distance difference is less than or equal to the second preset threshold P2, the wear of the surface rotating shaft 132 is relatively minor, and the air conditioner can continue to operate.

[0073] When the roughness difference exceeds the first preset threshold P1 and the distance difference exceeds the second preset threshold P2, it indicates that the wear on the inner surface of the bearing hole 1311 in the bearing housing 131 is quite severe, significantly affecting the fan's rotation. Therefore, the rotating assembly 13 needs to be addressed. This addressing may include the air conditioner's control system issuing a warning message to alert the user that there is a significant problem with the air conditioner's operation, requiring replacement of the bearing housing 131 and / or the rotating shaft 132 in the rotating assembly 13 to ensure the air conditioner's normal operation.

[0074] In this example, the roughness difference value and at least two position points of the rotating component 13 after the air conditioner has been running for a predetermined time are first obtained. Then, the motion state of the rotating component 13 is processed according to the relationship between the roughness difference value and a first preset threshold P1, and the relationship between the distance difference between the at least two position points and a second preset threshold P2. Based on this, users can detect any problems with the operating state of the rotating component 13 during air conditioner operation in the first instance. When problems are found, users can promptly contact staff to address the issues, thereby improving product reputation and user experience. It also shortens the time required for staff to troubleshoot air conditioner operation problems, improving after-sales efficiency.

[0075] In one example, when the roughness difference exceeds the first preset threshold P1, it indicates that there is severe wear in the rotating component 13, which may significantly affect the use of the fan component 12. Therefore, further judgment can be made by combining other judgment conditions.

[0076] Reference Figure 7 As shown, when the roughness value is greater than the first preset threshold P1, at least two position points on the rotating assembly 13 are obtained. Specifically, the position regions of the at least two position points on the rotating shaft 132 in the rotating assembly 13 can be obtained by detection components such as position sensors, and the distance difference S between the at least two position points can be calculated.

[0077] When the distance difference S is greater than the second preset threshold P2, combined with the above-mentioned logic condition that the roughness difference is greater than the first preset threshold P1, it indicates that there is severe wear in the rotating component 13, which will have a significant impact on the use of the fan component 12, thereby reducing the utilization rate of the air conditioner. Specifically, the wear in the rotating component 13 may be on the inner surface of the bearing hole 1311 in the bearing housing 131, or on the surface of the rotating shaft 132 (the surface that contacts the inner surface of the bearing hole), or both the inner surface of the bearing hole 1311 and the surface of the rotating shaft 132 may have severe wear.

[0078] Therefore, the usage status of the rotating component 13 needs to be addressed. For example, after the air conditioner's control system obtains information or signals about the wear condition, it can issue a warning to remind the user that the air conditioner is operating at a high temperature and needs to be addressed promptly to avoid further problems. During the process, the user can contact the air conditioner's after-sales service personnel to replace the bearing housing 131 and / or the rotating shaft 132.

[0079] In one example, if the roughness difference is greater than the first preset threshold P1, and the distance difference S between at least two points on the rotating shaft 132 is greater than the second preset threshold P2, it can be determined that the wear in the bearing housing 131 has exceeded the limit value. Specifically, the wear on the inner surface of the bearing hole 1311 in the bearing housing 131 may be severe; or the wear on the surface of the rotating shaft 132 may be severe; or both the inner surface of the bearing hole 1311 and the surface of the rotating shaft 132 may have severe wear.

[0080] The aforementioned wear condition allows the electrical signals from the sensors detecting roughness and position to be transmitted to the air conditioner's control system. Upon receiving the corresponding electrical signals, the control system issues a warning message, which can be displayed on the air conditioner's screen or sent to the user's mobile phone or computer. This reminds the user to address any issues with the air conditioner's operation promptly, such as replacing the bearing housing 131 and / or the rotating shaft 132, to ensure normal operation of the air conditioner. This improves user experience and product reputation, and also reduces the time required for technicians to troubleshoot air conditioner malfunctions, thus improving after-sales efficiency.

[0081] like Figure 7 and combined Figure 5 As shown, in some embodiments, after the air conditioner is installed in place, the highest point of the rotating shaft is defined as the first initial position point W. 初 1. The lowest point of the rotating shaft 132 is the second initial position point W. 初 2. First initial position point W 初 1 and the second initial position point W 初 2. The factory condition of the rotating shaft 132 can be divided and recorded.

[0082] The location points include a first location point W1 and a second location point W2. After the air conditioner has preset a predetermined time, the first initial location point W1 will be... 初 1. Move to the first position point W1, and the second initial position point W. 初 2. Move to the second position point W2.

[0083] Wherein, after the air conditioner has been running for the scheduled time, if the first initial position point W 初 1 and the first position point W1 coincide, and the second initial position point W 初 The fact that position 2 coincides with the second position point W2 indicates that there is no wear in the bearing housing 131 and / or rotating shaft 132, and the fan assembly 12 in the air conditioner is operating normally.

[0084] And when the first initial position point W 初 1. There is a deviation between the position of the first position point W1 and / or the second initial position point W. 初 When there is a deviation between position 2 and the second position point W2, it indicates that after the air conditioner has been running for a predetermined time, the inner surface of the bearing hole 1311 and / or the surface of the rotating shaft 132 have been worn during rotation, and the wear has affected the operation of the air conditioner.

[0085] After the air conditioner has been running for a predetermined time, the position sensors detect the instantaneous positions of the first position point W1 and the second position point W2, and calculate the distance difference S between the two positions, i.e., distance difference S = |W1 - W2|. In another example, the central axis of the rotation shaft 132 can also be defined as L, and there can be two distance differences: the first distance difference is |W1 - L|, and the second distance difference is |W2 - L|.

[0086] After the distance difference S is determined, the operating status of some components (such as fan assembly 12) in the air conditioner is judged according to the relationship between the distance difference S and the second preset threshold P2. The specific judgment process can be found in the above embodiment, and will not be repeated here.

[0087] Reference Figure 7 As shown, in some embodiments, the process of obtaining the roughness difference of the inner surface of the bearing bore of the bearing housing 131 in the rotating assembly 13 and at least two location points can be achieved by the following method:

[0088] First, the contact surface of the rotating assembly 13 is determined. Then, after a preset time by the air conditioner, the roughness difference of the contact surface and two position points are obtained using existing detection methods. For example, the roughness difference of the inner surface of the bearing hole 1311 is obtained using a length sensor, and two position points on the rotating shaft 132 are obtained using a position sensor.

[0089] In determining the contact surface of the rotating assembly 13, the first contact surface S1 and the second contact surface S2 can be determined by dividing the contact area between the rotating shaft 132 and the bearing hole 1311.

[0090] In one example, the process of dividing the contact area between the rotating shaft 132 and the bearing hole 1311 is as follows: After the air conditioner is installed, the contact area is divided based on the central axis L1 of the bearing hole 1311, which is parallel to the horizontal plane. The contact area located above the central axis L1 is the first contact surface S1, and the contact area located below the central axis L1 is the second contact surface S2.

[0091] Once the first contact surface S1 and the second contact surface S2 are determined, and the air conditioner has been running for a predetermined time, the first roughness difference of the first contact surface S1 and the second roughness difference of the second contact surface S2 are determined.

[0092] The first roughness difference is used to characterize the difference between the first initial roughness value of the first contact surface S1 and the first roughness value of the first contact surface S1 after a predetermined time, and the second roughness difference is used to characterize the difference between the second initial roughness value of the second contact surface S2 and the second roughness value of the second contact surface S2 after a predetermined time.

[0093] It should be noted that the first and second initial roughness values ​​can be tested and recorded at the factory after the bearing housing 131 is manufactured. The first and second roughness values ​​can be detected and obtained using a length sensor.

[0094] After the first roughness difference and the second roughness difference are calculated, they are compared with the first preset threshold P1. If the first roughness difference is greater than the first preset threshold P1, or the second roughness difference is greater than the first preset threshold P1, or both the first roughness difference and the second roughness difference are greater than the first preset threshold P1, it indicates that the inner surface of the bearing hole 1311 may have experienced relatively severe relative wear during the operation of the air conditioner for the predetermined time.

[0095] Then, further, based on the relationship between the distance difference S between the first position point and the second position point and the second preset threshold P2, it is determined whether the wear on the inner surface of the bearing hole 1311 has had a significant impact on the rotation of the fan assembly 12.

[0096] When the distance difference S is greater than the second preset threshold P2, it indicates that the wear on the inner surface of the bearing hole 1311 is relatively severe and has a significant impact on the rotation of the fan assembly 12. For example, it may cause the fan to jump or rotate eccentrically during rotation. At this time, by alerting the user to the above abnormal movement state, the user can quickly deal with the abnormal movement state, thereby ensuring the normal operation of the air conditioner.

[0097] In this embodiment, based on the magnitude of the first roughness difference and the second roughness difference, and in conjunction with the judgment of the relationship between the distance difference S and the second preset threshold P2, users or after-sales personnel can be accurately informed of the cause of the abnormal operation of the fan in a timely manner, thereby effectively improving the user experience and product reputation. At the same time, it can also effectively shorten the time for after-sales personnel to troubleshoot air conditioner operation problems and improve after-sales efficiency.

[0098] like Figure 8 As shown, an example embodiment of the present invention provides an air conditioner 100. The air conditioner 100 includes a processor 101 and a memory 102 connected to the processor 101. The memory 102 stores computer-executable instructions. These computer-executable instructions can be invoked by the processor 101 to execute the air conditioning control method described in the above embodiment.

[0099] In the above scheme, the first roughness difference value of the first contact surface S1 and the second roughness difference value of the second contact surface S2 on the inner surface of the bearing hole 1311 in the bearing housing 131 of the rotating assembly 13 after a predetermined running time are obtained, and the distance difference S between the first position point and the second position on the rotating shaft 132 is obtained. When the first roughness difference value is greater than the first preset threshold P1, or the second roughness difference value is greater than the first preset threshold P1, or both the first roughness difference value and the second roughness difference value are greater than the first preset threshold P1, and the distance difference S is greater than the second preset threshold P2, it is determined that there is a relatively serious wear condition on the inner surface of the bearing hole 1311. After determining that there is wear condition affecting the fan rotation in the air conditioner, the user can take timely and effective measures based on the above wear condition, such as contacting after-sales personnel to replace the air conditioner components.

[0100] Therefore, based on the implementation of the above solution, users can detect whether there are any problems with the inner surface of the bearing hole 1311 or the condition of the rotating shaft 132 during the operation of the air conditioner in the first instance.
