[0037] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of this application, and should not be construed as limiting the embodiments of this application.

[0038] Please see Figure 1 This application provides a control method for an air conditioner. The control method includes:

[0039] 01: With the fresh air duct detection function of the air conditioner turned on, detect the power of the centrifugal fan of the air conditioner's fresh air module when the first duct is open and the power of the axial fan when the second duct is open;

[0040] 03: Determine the continuity status of the fresh air duct based on the power of the centrifugal fan and the axial fan;

[0041] 05: Issue a maintenance alarm when the fresh air duct is blocked.

[0042] Please see Figures 2 to 11 This application also provides an air conditioner 100. The air conditioner 100 includes a fresh air module 110 and a controller 120. The lower part of the air conditioner 100 of this application is the fresh air module 110, and the upper part of the air conditioner 100 is the controller 120.

[0043] The fresh air module 110 includes a purification valve 111, an axial flow fan 113, a centrifugal fan 112 located downstream of the purification valve 111, an air outlet valve 114, an exhaust duct valve 116, and a fresh air duct valve 115.

[0044] The fresh air module 110 comprises an internal circulation channel 101, an exhaust channel 103, and a fresh air channel 102. The indoor air inlet 1011 of the internal circulation channel 101 is equipped with a purification valve 111, and the indoor air outlet 1012 of the internal circulation channel 101 is equipped with an outlet valve 114. The exhaust channel 103 connects the fresh air channel 102 and the internal circulation channel 101. The outdoor air inlet of the fresh air channel 103 is equipped with a fresh air channel valve 115.

[0045] When the air conditioner 100 turns on the internal circulation mode, indoor air is introduced into the fresh air module 110 through the purification valve 111. The air is purified in the fresh air module 110 through the axial flow fan 113 and the internal circulation channel 101, and then discharged into the room through the air outlet valve 114 after passing through the centrifugal fan 112.

[0046] When the air conditioner 100 turns on the fresh air mode, outdoor air is introduced into the fresh air module 110 through the fresh air duct valve 115 and the fresh air duct 102, and then discharged into the room through the air outlet after passing through the centrifugal fan 112.

[0047] When the air conditioner 10 turns on the exhaust mode, indoor air is introduced into the fresh air module 110 through the purification valve 111, and after passing through the axial flow fan 113, the internal circulation channel 101 and the centrifugal fan 112, it is transmitted from the exhaust channel 103 to the fresh air channel 102, and then discharged to the outside through the fresh air channel valve 115.

[0048] The controller 120 is used to detect the power of the centrifugal fan 112 in the first duct connection state and the power of the axial fan 113 in the second duct connection state when the fresh air duct detection function of the air conditioner 100 is turned on, and to determine the fresh air duct connection state based on the power of the centrifugal fan 112 and the power of the axial fan 113, and to issue a maintenance alarm prompt when the fresh air duct is blocked.

[0049] First, when the air conditioner 100 activates the fresh air duct detection function, it detects the power of the centrifugal fan 112 in the first duct connection state and the power of the axial fan 113 in the second duct connection state of the air conditioner 100's fresh air module 110. That is, the air conditioner 100 of this application can automatically perform fresh air duct detection without any other manual operation after the user activates the fresh air duct detection function, making it more intelligent.

[0050] The measurement of the power of the centrifugal fan 112 in the fresh air module 110 of the air conditioner 100 when the first duct is open refers to the system entering fresh air mode, when the air conditioner 100 begins data acquisition and measures the power p1 of the centrifugal fan 112. The first duct is the duct through which the air in the air conditioner 100 passes when it is in fresh air mode, such as... Figure 8 and Figure 9 The pipe indicated by the middle arrow.

[0051] The power of the axial fan 113 in the fresh air module 110 of the air conditioner 100 when the second duct is open refers to the power p2 of the axial fan 113 when the system enters the exhaust function mode and the air conditioner 100 begins data acquisition. The second duct is the duct through which the air in the air conditioner 100 passes when the air conditioner 100 is in exhaust function mode. Figure 10 and Figure 11 The pipe shown by the arrow in the diagram.

[0052] It should be noted that the air conditioner 100 of this application has both fresh air and exhaust functions.

[0053] Then, the continuity status of the fresh air duct is determined based on the power of the centrifugal fan 112 and the axial fan 113. In detection mode, this application obtains the power p1 of the centrifugal fan 112 and the power p2 of the axial fan 113. By comparing the power difference between the centrifugal fan 112 and the axial fan 113 in detection mode and the power in the initial state, it is determined whether the fresh air duct of the air conditioner 100 is blocked.

[0054] Finally, when the fresh air duct is blocked, the air conditioner 100 can be triggered to issue a maintenance alarm. The maintenance alarm can be a voice prompt or a light prompt; the method of prompting is not limited here.

[0055] Thus, this application, by analyzing changes in fan power, can determine whether the fresh air duct of an air conditioner 100 with both fresh air and exhaust functions is blocked, thereby completing the detection of whether the fresh air duct is blocked. Furthermore, when the fresh air duct is blocked, the air conditioner 100 can be triggered to issue a maintenance alarm, further enhancing the user experience.

[0056] Understandably, when determining whether the fresh air duct is blocked, this application first tests the power of the centrifugal fan 112 with the air conditioner 100 in fresh air mode to determine the risk of blockage in the air conditioner 100. If it is determined that there is no risk of blockage in the air conditioner 100, then it is not necessary to test the power of the axial fan 113, thereby improving the testing efficiency.

[0057] Specifically, please refer to Figure 12 Step 01 includes:

[0058] 011: When the fresh air duct detection function of the air conditioner is turned on, control the air conditioner to turn on the fresh air mode and turn on the centrifugal fan to detect the power of the centrifugal fan when the fresh air module is in the first duct open state;

[0059] 012: When the difference between the power of the centrifugal fan and the first initial power is greater than the first power threshold, control the centrifugal fan to shut down and start the exhaust mode, and start the axial flow fan to detect the power of the axial flow fan in the second pipeline conduction state.

[0060] Please combine Figure 2 The controller 120 is used to control the air conditioner 100 to turn on the fresh air mode when the fresh air duct detection function is turned on, and to turn on the centrifugal fan 112 to detect the power of the centrifugal fan 112 when the fresh air module is in the first duct open state; when the difference between the power of the centrifugal fan 112 and the first initial power p01 is greater than the first power threshold, the controller 120 controls the centrifugal fan 112 to turn off and turn on the exhaust mode, and turns on the axial fan 113 to detect the power of the axial fan 113 when the fresh air module is in the second duct open state.

[0061] Specifically, when the air conditioner 100 activates the fresh air duct detection function, it controls the air conditioner 100 to switch to fresh air mode, and activates the centrifugal fan 112 to detect the power p1 of the centrifugal fan 112 in the first duct open state through the fresh air module 110. That is, the fresh air mode is activated, and the exhaust function is deactivated, thereby controlling the air conditioner 100 to activate the fresh air mode, and obtaining the power p1 of the centrifugal fan 112 in the first duct open state through the centrifugal fan 112 detection module 110.

[0062] This application requires correction of the first initial power p01 of the centrifugal fan 112 and the second initial power p02 of the axial fan 113 in their initial state. Then, the difference between the power p1 of the centrifugal fan 112 and the first initial power p01 is compared to determine whether there is a risk of blockage in the fresh air duct.

[0063] Understandably, when the centrifugal fan 112 of the air conditioner 100 is turned on, the first initial power p01 corresponding to an unobstructed fresh air duct during the test speed test is related to the model of the centrifugal fan 112 and the length of the duct. When the axial fan 113 of the air conditioner 100 is turned on, the second initial power p02 corresponding to an unobstructed fresh air duct during the test speed test is mainly related to the model of the axial fan 113 and the length of the duct.

[0064] Specifically, when the difference between the power p1 of the centrifugal fan 112 and the first initial power p01 is greater than the first power threshold, the centrifugal fan 112 is controlled to shut down and the exhaust mode is turned on, and the axial fan 113 is turned on to detect the power of the axial fan 113 when the fresh air module is in the second pipeline conduction state. The first power threshold is the system default setting value of the air conditioner 100.

[0065] In other words, the difference between the power p1 of the centrifugal fan 112 and the first initial power p01 is |p1-p01|. When |p1-p01| < the first power threshold, it indicates that the fresh air duct is not blocked; when |p1-p01| > the first power threshold, it indicates that there is a risk of blockage in the fresh air duct. Understandably, a large difference between the real-time detected power p1 of the centrifugal fan 112 and the first initial power p01 after initial state correction indicates a change in the operation of the centrifugal fan 112. Therefore, the large difference between the current power p1 and the first initial power p01 may be due to blockage in the fresh air duct.

[0066] Therefore, only after detecting the power of the centrifugal fan 112 indicates a risk of blockage in the fresh air duct, is it necessary to further detect the power of the axial fan 113 to accurately determine whether the fresh air duct is blocked. That is, if the difference between the power of the centrifugal fan 112 and the first initial power p01 is greater than the first power threshold, the centrifugal fan 112 is shut down and the exhaust mode is activated, while the axial fan 113 is activated to detect the power of the axial fan 113 in the second duct continuity state of the fresh air module 110.

[0067] Thus, based on determining the risk of blockage in the fresh air duct of the air conditioner 100 by detecting the power of the centrifugal fan 112, the power of the axial fan 113 is then detected to determine whether the fresh air duct of the air conditioner 100 is indeed blocked, making the detection results more accurate.

[0068] Furthermore, the absolute value of the difference between the power of the centrifugal fan 112 when the fresh air duct is blocked and the power of the fresh air duct 102 when it is unobstructed is related to the model of the centrifugal fan 112 and the length of the fresh air duct. Similarly, the absolute value of the difference between the power of the axial fan 113 when the fresh air duct 102 is blocked and the power of the fresh air duct 102 when it is unobstructed is related to the model of the axial fan 113 and the length of the fresh air duct.

[0069] For more details, please refer to Figure 13 Step 011 includes:

[0070] 0111: Controls the opening of the air outlet valve and the fresh air duct valve of the fresh air module, and controls the closing of the purification valve, in order to detect the power of the centrifugal fan of the fresh air module when the first pipeline is open.

[0071] Please combine Figure 2 The controller 120 is used to control the opening of the air outlet valve 114 and the fresh air channel valve 115 of the fresh air module 110, and to control the closing of the purification valve 111, so as to detect the power of the centrifugal fan 112 of the fresh air module 110 in the first pipeline conduction state.

[0072] Please see Figure 8 and Figure 9 When it is necessary to detect the power of the centrifugal fan in the fresh air module 110 with the first pipeline open, the outlet valve 114 of the fresh air module 110 can be opened, i.e. Figure 8 When the central air outlet valve 114 is pushed open in the direction of F1, the fresh air duct valve 115 opens, which means... Figure 8 The fresh air duct valve 115 changes from a horizontally closed state to a vertically open state, controlling the purification valve 111 to close. Figure 9When the purification valve 111 is pushed in the F2 direction, it becomes closed, thus creating the first pipeline connection and allowing the air conditioner to enter the fresh air mode.

[0073] For more details, please refer to Figure 14 Step 012 includes:

[0074] 0121: Control the air outlet valve of the fresh air module to close, and control the fresh air duct valve and purification valve to open, in order to detect the power of the axial flow fan of the fresh air module when the second pipeline is open.

[0075] Please combine Figure 2 The controller 120 is used to control the air outlet valve 114 of the fresh air module 110 to close, and to control the fresh air channel valve 115 and the purification valve 111 to open, so as to detect the power of the axial flow fan 113 of the fresh air module 110 in the second pipeline conduction state.

[0076] Please see Figure 10 and Figure 11 When it is necessary to detect the power of the axial fan in the fresh air module 110 with the second pipeline in operation, the outlet valve 114 of the fresh air module 110 can be closed, i.e. Figure 10 The central air outlet valve 114 is pushed open in the F3 direction to close, and controls the purification valve 111 and the fresh air duct valve 115 to open, which is... Figure 11 The central purification valve 111 is pushed open in the F4 direction. Figure 10 When the valve 115 of the fresh air duct changes from being closed in the horizontal direction to being opened in the vertical direction, the fresh air function of the air conditioner 100 is turned off, the exhaust function is turned on, the centrifugal fan 112 stops running, and the axial fan 113 starts running, thus forming a state of second pipeline conduction, so that the air conditioner 100 enters the exhaust mode.

[0077] The following describes how to determine whether the fresh air duct is blocked, given that the power of the centrifugal fan 112 and the axial fan 113 have been detected.

[0078] Please see Figure 15 Step 03 includes:

[0079] 031: If the difference between the power of the centrifugal fan and the first initial power is greater than the first power threshold, and the difference between the power of the axial fan and the second initial power is greater than the second power threshold, the fresh air duct is determined to be blocked; or

[0080] 032: If the difference between the power of the centrifugal fan and the first initial power is not greater than the first power threshold, or the difference between the power of the axial fan and the second initial power is not greater than the second power threshold, the fresh air duct is determined to be in an unblocked state.

[0081] Please combine Figure 2 The controller 120 is used to determine that the fresh air duct is blocked when the difference between the power of the centrifugal fan 112 and the first initial power p01 is greater than the first power threshold and the difference between the power of the axial fan 113 and the second initial power p02 is greater than the second power threshold; or to determine that the fresh air duct is unblocked when the difference between the power of the centrifugal fan 112 and the first initial power p01 is not greater than the first power threshold, or the difference between the power of the axial fan 113 and the second initial power p02 is not greater than the second power threshold.

[0082] If the difference between the power p1 of centrifugal fan 112 and the first initial power p01 is greater than the first power threshold, and the difference between the power p2 of axial fan 113 and the second initial power p02 is greater than the second power threshold, the fresh air duct is determined to be blocked. The first power threshold is the system default setting value of the air conditioner 100. Understandably, as explained above, if the difference between the power p1 of centrifugal fan 112 and the first initial power p01 is greater than the first power threshold, it indicates a risk of blockage in the fresh air duct. Similarly, if the difference between the power p2 of axial fan 113 and the second initial power p02 is greater than the second power threshold, it means that the real-time detected power p2 of axial fan 113 differs significantly from the second initial power p02 corrected from the initial state. This indicates a change in the operation of axial fan 113. Therefore, the blockage in the fresh air duct is the cause of the large difference between the current power p2 of axial fan 113 and the second initial power p02, thus confirming that the fresh air duct is blocked.

[0083] Furthermore, if the difference between the power p1 of the centrifugal fan 112 and the first initial power p01 is not greater than the first power threshold, or the difference between the power p2 of the axial fan 113 and the second initial power p02 is not greater than the second power threshold, the fresh air duct is determined to be in an unblocked state. Understandably, as explained above, if the difference between the power p1 of the centrifugal fan 112 and the first initial power p01 is less than the first power threshold, it indicates that there is no risk of blockage in the fresh air duct, and thus it can be determined that the fresh air duct is in an unblocked state. Additionally, even if the difference between the power p1 of the centrifugal fan 112 and the first initial power p01 is detected to be greater than the first power threshold, if the difference between the power p2 of the axial fan 113 and the second initial power p02 is less than the second power threshold, the fresh air duct can still be determined to be in an unblocked state.

[0084] Therefore, the above judgment method can more accurately determine whether the fresh air duct is blocked.

[0085] Once it is determined that the fresh air duct is blocked, this application can clear the blockage using the exhaust function of the air conditioner 100.

[0086] Specifically, please refer to Figure 16 The control methods for air conditioners include:

[0087] 06: If the fresh air duct is blocked and the air conditioner is in fresh air deblocking mode, the exhaust function will be continuously turned on at the preset power for the first time to clear the blockage.

[0088] Please combine Figure 2 The controller 120 is used to continuously run the exhaust function at a preset power for a first duration to clear the blockage when the fresh air duct is blocked and the air conditioner 100 is in the fresh air deblocking mode.

[0089] The preset power can be the maximum power of the axial flow fan 113. The power of the axial flow fan 113 is determined by the rotation speed. Therefore, when controlling the axial flow fan 113 to operate at the maximum power, the rotation speed of the axial flow fan 113 can be adjusted to the maximum.

[0090] The first duration is the system default setting duration of the air conditioner 100. For example, the first duration can be any value from 600S to 1200S, that is, the first duration can be 10 minutes, 11 minutes, 12 minutes, 13 minutes, 14 minutes, 15 minutes, 16 minutes, 17 minutes, 18 minutes or 20 minutes, without any restrictions.

[0091] That is, after determining that the difference between the power of the axial fan 113 and the second initial power is greater than the second power threshold by turning on the exhaust function as described above, the exhaust function can continue to be turned on, and the speed of the axial motor 113 can be adjusted to the maximum so that the exhaust capacity of the air conditioner 100 reaches the maximum, blowing out the material blocking the fresh air duct, thereby cleaning the fresh air duct and removing the blockage.

[0092] In addition, when the fresh air duct detection function is enabled on the air conditioner 100, the user can turn off the air conditioner to exit the fresh air duct detection function.

[0093] Specifically, please refer to Figure 17 The control methods for air conditioners include:

[0094] 07: When the air conditioner has the fresh air duct detection function enabled, receive the user's first control command to turn off the air conditioner to control the air conditioner to exit the fresh air duct detection function.

[0095] Please combine Figure 2The controller 120 is used to receive the user's first control command to turn off the air conditioner when the air conditioner 100 has the fresh air duct detection function enabled, so as to control the air conditioner 100 to exit the fresh air duct detection function.

[0096] The first control command for the user to turn off the air conditioner can be a control command issued by the user clicking the off button on the remote control of the air conditioner 100, or a voice command such as "turn off the air conditioner" issued by the user, and there are no restrictions here.

[0097] In addition, if the user does not want the air conditioner 100 to perform the fresh air duct detection function but still wants the air conditioner 100 to continue working, the user can exit the fresh air duct detection function by clicking the corresponding button on the remote control of the air conditioner 100.
