[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. The fan assembly 12 is disposed within the frame 11 and may include a fan and a motor for driving the fan to rotate. The fan may include, but is not limited to, an axial fan. The fan assembly 12 is connected to the frame 11 via a rotating component 13.

[0055] Reference Figure 1 and combined Figures 2 to 4 As shown, the rotating assembly 13 includes a bearing housing 131 and a rotating shaft 132. The bearing housing 131 can be disposed on one of the vertical plates 111 within the frame 11.

[0056] One end of the rotating shaft 132 is inserted into the bearing housing 131, and the two ends of the rotating shaft 132 and the bearing housing 131 are in a hole-shaft fit relationship. The other end of the rotating shaft 132 passes through the fan assembly 12. Specifically, the other end of the rotating shaft 132 passes through the fan and is connected to the output end of the motor so that it can rotate under the drive of the motor, thereby driving the fan to rotate.

[0057] The air conditioner also includes a position sensor (not shown in the figure) for detecting distance. This 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.

[0058] In one example, the bearing housing 131 is made of rubber. Driven by the motor, the end of the rotating shaft 132 away from the motor rotates along the central axis of the rotating shaft 132 within the bearing housing 131. With prolonged operation of the air conditioner, the rubber bearing housing 131 or the rotating shaft 132 is prone to wear. This wear can cause the fan to jerk or exhibit eccentric abnormal movements during rotation. These abnormal movements not only affect fan rotation but also reduce the user experience of the air conditioner.

[0059] In order to enable users to detect the wear condition of the bearing housing 131 or 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 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 6 As shown, an exemplary embodiment of the present invention provides an air conditioning control method, which includes the following steps:

[0061] S100: Obtain the stress 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 stress value difference and the first preset threshold, and based on the relationship between the distance difference between at least two location points and the second preset threshold, the operating status of the rotating component is warned and processed.

[0063] Reference Figure 7 As shown, in step S100, after the air conditioner is installed and has been running for a predetermined time, the rotating component 13 in the air conditioner may experience wear, causing the fan assembly 12 to malfunction. The predetermined time can be flexibly set based on experimental or empirical values; for example, it can be an integer multiple of one month. The specific value of the predetermined time is not specifically limited here.

[0064] To promptly ascertain the operating status of the air conditioner, after a predetermined operating time, a pressure sensor (not shown in the figure) is used to acquire the stress value in the rotating assembly 13. Specifically, in this step and the following embodiments, the rotating assembly 13, comprising a bearing housing 131 and a rotating shaft 132, is used as an example. Existing detection methods can be used to acquire the stress value of the rotating shaft 132 in the rotating assembly 13. The stress value difference in this step is used to characterize the difference between the initial stress value of the rotating shaft 132 and the stress value of the rotating shaft 132 after a predetermined operating time. The initial stress value of the rotating shaft 132 can be tested and recorded at the factory after the rotating shaft 132 is manufactured.

[0065] And at least two position points in the rotating assembly 13 are acquired using a position sensor (not shown in the figure). Specifically, at least two position points on the rotating shaft 132 can be acquired 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 of the rotating shaft 132.

[0066] Continue to refer to Figure 7 As shown, in step S200, the relationship between the stress value difference and the first preset threshold P1 includes the following two types:

[0067] Firstly, when the stress difference is less than or equal to the first preset threshold P1, it indicates that the wear of the rotating shaft 132 and / or the wear of the bearing housing 131 are within the allowable range of wear, and the air conditioner can continue to operate.

[0068] Secondly, when the stress difference is greater than the first preset threshold P1, it indicates that the wear of the rotating shaft 132 and / or the bearing housing 131 may be quite severe, which will have a significant impact on the rotation of the fan.

[0069] It should be noted that the value of the first preset threshold P1 can be set by those skilled in the art based on experiments or experience in actual applications, and the value or range of the first preset threshold P1 is not specifically limited here.

[0070] Therefore, when the stress difference exceeds 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. Similarly, the value of the second preset threshold P2 can be set by those skilled in the art based on experiments or experience in practical applications; the specific value or range of the second preset threshold P2 is not limited here. It should be noted that in this example, the number of location points can be two, three, four, or more.

[0071] 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.

[0072] When the stress difference exceeds the first preset threshold P1 and the distance difference exceeds the second preset threshold P2, it indicates that the wear of the rotating shaft 132 is quite severe and has a significant impact on the fan's rotation. Therefore, it is necessary to warn and address the operating status of the rotating component 13. Specifically, the air conditioner's control system can issue a warning message to remind the user that there is a significant problem with the air conditioner's operation and that timely action is required to ensure its normal operation.

[0073] In this embodiment, after obtaining the stress value difference and at least two position points of the rotating component of the air conditioner after a predetermined running time, the rotation status of the rotating component 13 is alerted and processed based on the relationship between the stress value difference and the first preset threshold P1, and based on the relationship between the distance difference of the at least two position points and the second preset threshold P2. Therefore, users can discover whether there is a problem with the usage status of the rotating component 13 during the operation of the air conditioner in the first time. When there is a problem with the usage status of the rotating component 13, users can contact staff in a timely manner to handle the rotating component 13, thereby improving the user experience and product reputation. At the same time, it can also shorten the time for staff to go to the site to check the air conditioner operation problem and improve after-sales efficiency.

[0074] Reference Figure 7 As shown, in some embodiments, step S200 includes the following steps: when the stress difference is greater than a first preset threshold P1, it indicates that there is severe wear in the rotating assembly 13, which may have a significant impact on the use of the fan assembly. Therefore, further judgment is needed in conjunction with other judgment conditions.

[0075] Reference Figure 5 and combined Figure 7 As shown, when the stress difference is greater than a first preset threshold P1, the distance difference S between at least two positions on the rotating assembly 13 is obtained. Specifically, taking the rotating assembly 13, which includes a bearing housing 131 and a rotating shaft 132, as an example, at least two positions on the rotating shaft 132 can be obtained.

[0076] The system can obtain the positions of at least two locations using detection components such as position sensors, and calculate the distance difference S between these two locations. When this distance difference S is greater than a second preset threshold P2, combined with the logical condition that the stress difference is greater than a first preset threshold P1, it indicates that the wear of the rotating shaft 132 in the rotating assembly 13 is quite severe, significantly affecting the fan's rotation. Therefore, it is necessary to warn and address the usage status of the rotating assembly 13. Specifically, the air conditioner's control system can issue a warning message to remind the user that there is a significant problem with the air conditioner's operation and that timely action is needed to ensure its normal operation.

[0077] Reference Figure 7 As shown, in some embodiments, when the stress difference is greater than the first preset threshold P1, and when the distance difference is greater than the second preset threshold P2, it is determined that the wear of the bearing housing 131 and / or the rotating shaft 132 exceeds the limit value. At this time, the air conditioning control system issues a warning to remind the user to deal with the problems in the operation of the air conditioning in a timely manner and replace the bearing housing 131 and / or the rotating shaft 132 in a timely manner.

[0078] Reference Figure 7 As shown, it should be noted that in this example, when the stress difference is greater than the first preset threshold P1, it can be basically determined that there is wear in the contact area between the bearing housing 131 and the rotating shaft 132. When the distance difference between at least two positions is less than or equal to the second preset threshold P2, the bearing housing 131 is worn; and when the distance difference S between at least two positions is greater than the second preset threshold P2, the rotating shaft 132 is worn, or both the rotating shaft 132 and the bearing housing 131 are worn, and the above wear has had a significant impact on the rotation of the fan assembly 12. Therefore, it is necessary to replace the bearing housing 131 and / or the rotating shaft 132 to ensure the normal operation of the air conditioner.

[0079] In this example, by combining the above-mentioned stress value difference and the first preset threshold P1 with the distance difference S and the second preset threshold P2, users can know in the first instance whether there is a problem with the operation of the fan assembly 12 in the air conditioner. Users can contact staff in a timely manner to handle the rotating assembly 13, thereby improving the user experience and product reputation. At the same time, it can also shorten the time for staff to come to the site to check the air conditioner operation problem and improve after-sales efficiency.

[0080] like Figure 5 As shown, in some embodiments, after the air conditioner is installed in place, the highest point of the rotating shaft 132 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.

[0081] 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... 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.

[0082] When the first initial position point W 初 1 coincides with the first position point W1, and the second initial position point W 初 When position 2 coincides with the second position point W2, it indicates that the rotating shaft 132 has not been worn after the air conditioner has been running for a predetermined time, and the fan assembly 12 in the air conditioner is operating normally.

[0083] 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 rotating shaft 132 has been worn during rotation, or there is wear in both the rotating shaft 132 and the bearing housing 131.

[0084] After the air conditioner has been running for a predetermined time, the positions of the first position point W1 and the second position point W2 can be detected using position sensors. Then, the distance difference S is determined by the distance between the first position point W1 and the second position point W2, i.e., the distance difference S is |W1-W2|; or, the central axis of the rotating shaft 132 is defined as L, and there can be two distance differences, the first distance difference being |W1-L| and the second distance difference being |W2-L|.

[0085] After the distance difference is determined, the operating status of the fan assembly 12 in the air conditioner is judged according to the relationship between the distance difference and the second preset threshold P2. The specific judgment process can be found in the above embodiment, and will not be repeated here.

[0086] Referring to Figure 4, in some embodiments, the stress value and at least two position points of the rotating component 13 after a predetermined running time can be obtained by the following method:

[0087] First, determine the contact surface of the rotating assembly 13. After the air conditioner has been running for a predetermined time, obtain the stress value of the contact surface and at least two location points based on existing detection methods. For example, use strain gauges to detect the stress value of the contact surface, and use position sensors to detect at least two location points, etc.

[0088] In one example, continue to refer to Figure 4 The contact surfaces of the rotating assembly 13 can be determined by dividing the contact area between the rotating shaft 132 and the bearing housing 131 in the rotating assembly 13, thereby determining the first contact surface S1 and the second contact surface S2.

[0089] The process of dividing the contact area is as follows:

[0090] After the air conditioner is installed, the contact area is divided based on the central axis L of the rotating shaft 132, which is parallel to the horizontal plane. The contact area located above the central axis L is the first contact surface S1, and the contact area located below the central axis L is the second contact surface S2.

[0091] It should be noted that, in another example, the contact area can be divided based on the central axis of the fan in the fan assembly 12 to determine the first contact surface S1 and the second contact surface S2.

[0092] Once the first contact surface S1 and the second contact surface S2 are determined, and after the air conditioner has been running for a predetermined time, the first stress value difference of the first contact surface S1 and the second stress value difference of the second contact surface S2 are determined.

[0093] The process of determining the first stress value difference and the second stress value difference can be as follows: first, obtain the first initial stress value of the first contact surface S1 and the second initial stress value of the second contact surface S2; after the air conditioner has been running for a predetermined time, obtain the first stress value of the first contact surface S1 and the second stress value of the second contact surface S2 through detection methods such as strain gauges.

[0094] Wherein, the difference between the first initial stress value and the first stress value is the first stress value difference, and the difference between the second initial stress value and the second stress value is the second stress value difference.

[0095] After the first stress difference and the second stress difference are determined, they are compared with the first preset threshold P1. When the first stress difference is greater than the first preset threshold P1, or the second stress difference is greater than the first preset threshold P1, or both the first stress difference and the second stress difference are greater than the first preset threshold P1, it indicates that relative wear has occurred between the rotating shaft 132 and the bearing housing 131 during the rotation process of the predetermined time.

[0096] Then, based on the relationship between the distance difference between the first position point and the second position point and the second preset threshold P2, it is determined whether the rotation of the rotating shaft 132 has had a significant impact on the rotation of the fan assembly 12.

[0097] When the difference in the first stress value is greater than the first preset threshold P1, or when the difference in the second stress value is greater than the first preset threshold P1, or when both the difference in the first stress value and the difference in the second stress value are greater than the first preset threshold P1, and after determining that the distance difference between the first position point and the second position point is greater than the second preset threshold P2, it indicates that the wear of the rotating shaft 132 is quite serious and has a significant impact on the rotation of the fan. Therefore, it is necessary to warn and address the usage status of the rotating shaft 132. Specifically, the air conditioner's control system can issue a warning message to remind the user that there is a significant problem with the air conditioner's operation. In this case, the rotating shaft 132 needs to be replaced promptly to ensure the normal operation of the air conditioner.

[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 stress difference on the first contact surface S1 and the second stress difference on the second contact surface S2 of the rotating shaft 132 in the rotating assembly 13 after the air conditioner has been running for a predetermined time are first obtained, and the distance difference between the first position point and the second position point on the rotating shaft 132 is obtained. When the first stress difference is greater than the first preset threshold P1, or the second stress difference is greater than the first preset threshold P1, or both the first stress difference and the second stress difference are greater than the first preset threshold P1, and the distance difference is greater than the second preset threshold P2, it can be determined that the rotating shaft 132 has a relatively serious wear condition.

[0100] Therefore, by implementing the above solution, users can detect any problems with the operation of the rotating shaft 132 during the operation of the air conditioner in the first instance. If there are any problems with the operation of the air conditioner, users can contact staff in a timely manner to handle the rotating shaft 132, which effectively improves the user experience and product reputation. At the same time, it can also effectively shorten the time for staff to come to the site to troubleshoot the air conditioner's operation and improve after-sales efficiency.

However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
