[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0027] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In the description of the embodiments, specific features, structures, materials, or characteristics can be combined in a suitable manner in any one or more embodiments or examples.

[0028] The terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0029] In the description of the present invention, unless otherwise stated, "a plurality of" means two or more.

[0030] The air-conditioning device includes a housing, a heat exchanger located inside the housing, and a blower. An air inlet and an air outlet are provided on the housing. The air flow generated by the blower enters the housing through the air inlet and exits the housing through the air outlet. The heat exchanger is used for heat exchange of the air flow passing through it.

[0031] The air-conditioning device includes a louver assembly located at the air outlet, and the louver assembly is used for adjusting the air outlet direction of the air outlet.

[0032] In Figure 1 the example of, the louver assembly includes a drive motor, a linkage mechanism, and a plurality of louvers 1.

[0033] The drive motor is used to drive the louver assembly to act to adjust the air outlet direction.

[0034] The linkage mechanism is an intermediate linkage component, connected to the drive motor and the louver 1, transmitting the driving force of the drive motor to the louver 1 to drive the louver 1 to rotate. The linkage mechanism includes a link 2, and the link 2 is linked with the louver 1.

[0035] A plurality of louvers 1 are rotatably installed at the air outlet.

[0036] The swinging blades 1 are arranged in parallel or approximately parallel.

[0037] In the swinging direction of the swinging blades 1, several swinging blades 1 are divided into middle - area swinging blades, first - side - area swinging blades and second - side - area swinging blades located on both sides of the middle - area swinging blades.

[0038] In some embodiments, all the numbers of the swinging blades are divided.

[0039] In some embodiments where the numbers of the swinging blades can be evenly distributed, all the numbers of the swinging blades are divided, and all the swinging blades are evenly divided into middle - area swinging blades, first - side - area swinging blades and second - side - area swinging blades located on both sides of the middle - area swinging blades.

[0040] For example, in the case of 12 swinging blades, the first - side - area swinging blades, the middle - area swinging blades and the second - side - area swinging blades all include 4 swinging blades.

[0041] In some embodiments where the numbers of the swinging blades cannot be evenly distributed, all the numbers of the swinging blades are divided. The numbers of the first - side - area swinging blades and the second - side - area swinging blades are the same, and the number of the middle swinging blades is different from the numbers of the first - side - area swinging blades and the second - side - area swinging blades. In some embodiments, in order to improve the uniformity of the distribution, the number of the middle swinging blades differs from the number of the first - side - area swinging blades (the number of the second - side - area swinging blades) by 1.

[0042] For example, in the case of 14 swinging blades, the first - side - area swinging blades and the second - side - area swinging blades both include 5 swinging blades, and the middle - area swinging blades include 4 swinging blades.

[0043] In some embodiments, part of the numbers of the swinging blades are divided. Several middle swinging blades are used as the middle - area swinging blades, and several swinging blades on both sides of the middle - area swinging blades are used as the first - side - area swinging blades and the second - side - area swinging blades.

[0044] For example, in the case of 10 swinging blades, the two middle swinging blades (the 5th and 6th swinging blades) are used as the middle - area swinging blades, the 2nd and 3rd swinging blades are used as the first - side - area swinging blades, and the 8th and 9th swinging blades are used as the second - side - area swinging blades.

[0045] In Figure 2 In the example of , the air - conditioning device further includes a swinging - blade angle detection module, a storage module and a control module.

[0046] The swinging - blade angle detection module is used to detect the angles of the middle - area swinging blades, the first - side - area swinging blades and the second - side - area swinging blades in the shutdown state.

[0047] In some embodiments, the swinging - blade angle detection module is a camera or a radar device arranged at or near the air outlet of the air - conditioning device.

[0048] In some embodiments, there is 1 swinging - blade angle detection module, which is opposite to the middle - area swinging blades.

[0049] In some embodiments, there are three vane angle detection modules, which are respectively opposite to the middle area vanes, the first side area vanes, and the second side area vanes. The detection accuracy can be improved.

[0050] The storage module is used to store the adjustable angle range and the alarm angle range of the middle area vanes, the first side area vanes, and the second side area vanes in the shutdown state.

[0051] The control module is used to obtain the detected angle of the vane angle detection module in the shutdown state, read the angle range stored in the storage module, adjust the vane angle when the detected angle is within the adjustable angle range for facilitating the control during the next startup; and output an alarm message when the detected angle is within the alarm angle range to remind the user to perform maintenance.

[0052] In some embodiments, the control module outputs a control signal to the drive motor of the vane assembly to adjust the vane angle by controlling the operation of the drive motor.

[0053] In some embodiments, the air conditioner device further includes an alarm module. The control module outputs the alarm message to the alarm module, and the alarm module gives an alarm.

[0054] Therefore, the air conditioner device can automatically identify the deviation of the vane angle and make automatic adjustment or give an alarm according to the deviation, so as to correct the vane deviation in time and ensure that the air outlet direction meets the user's needs.

[0055] In some embodiments, the adjustable angle range stored in the storage module is as follows: the deviation directions of the middle area vanes, the first side area vanes, and the second side area vanes are the same; the deviation directions of at least two of the middle area vanes, the first side area vanes, and the second side area vanes are the same and the deviation angle of the middle area vanes is not the maximum among the three.

[0056] The deviation directions of the middle area vanes, the first side area vanes, and the second side area vanes are the same. This situation may be due to the fact that the vanes in the three areas do not return to the correct position at the same time. In this case, the angle adjustment is performed first.

[0057] The deviation directions of at least two of the middle area vanes, the first side area vanes, and the second side area vanes are the same and the deviation angle of the middle area vanes is not the maximum among the three. This situation may be due to the fact that the vanes in the three areas do not return to the correct position at the same time. In this case, the angle adjustment is performed first.

[0058] In some embodiments, the alarm angle range stored in the storage module is as follows: the middle area vanes are outside the middle deviation angle range and the deviation angle of the middle area vanes is the maximum among the three; the middle area vanes are within the middle deviation angle range, and both the first side area vanes and the second side area vanes are outside the side deviation angle range.

[0059] The lateral deviation angle is greater than the middle deviation angle.

[0060] In some embodiments, when in the shutdown state, the swing blade and the connecting rod of the connecting rod mechanism form an angle of θ degrees, the middle deviation angle ranges from θ degrees ± A degrees. The lateral deviation angle ranges from θ degrees ± B degrees, where B > A.

[0061] The deviation angle of the middle area swing blade outside the middle deviation angle range is the maximum among the three; this situation indicates that the deviation angle of the middle area swing blade is greater than that of the first side area swing blade and the second side area swing blade, indicating a situation that requires maintenance, and an alarm message is output.

[0062] When the middle area swing blade is within the middle deviation angle range and both the first side area swing blade and the second side area swing blade are outside the lateral deviation angle range, it indicates that the middle area swing blade is normal, and both the first side area swing blade and the second side area swing blade are abnormal, indicating a situation that requires maintenance, and an alarm message is output.

[0063] To improve the alarm accuracy and avoid false alarms, the control device is used to output an alarm message when the detected angle is within the alarm range during multiple shutdown states.

[0064] In some embodiments, the control device is used to determine the average deviation angle of the middle area swing blade, the average deviation angle of the first side area swing blade, and the average deviation angle of the second side area swing blade when in the shutdown state; and compare the average values with the angle ranges stored in the storage module.

[0065] In some embodiments, the control device is used to determine the maximum deviation angle of the middle area swing blade, the maximum deviation angle of the first side area swing blade, and the maximum deviation angle of the second side area swing blade when in the shutdown state; and compare the maximum values with the angle ranges stored in the storage module.

[0066] In some embodiments, the control device is used to determine the deviation angle of the middle swing blade of the middle area swing blade, the deviation angle of the middle swing blade of the first side area swing blade, and the deviation angle of the middle swing blade of the second side area swing blade, and compare the deviation angles of the middle swing blades of the three areas with the angles stored in the storage module.

[0067] When the control module detects that the angle is within the adjustable angle range, it drives the middle area swing blade to adjust to within the middle deviation angle range or the normal angle through the drive motor.

[0068] In some embodiments, the storage module stores the number of steps of the drive motor corresponding to the deviation angle of the middle area swing blade to the normal angle, and the drive motor is controlled to rotate the corresponding number of steps to drive the middle area swing blade to adjust to within the middle deviation angle range or the normal angle.

[0069] In some embodiments, the middle area swing blades are driven by a driving motor, and whether the middle area swing blades are adjusted to within the middle deviation angle range or the normal angle is detected by a swing blade angle detection module. When the middle area swing blades are adjusted to within the middle deviation angle range or the normal angle, the driving motor is controlled to stop operating; otherwise, the adjustment continues.

[0070] In some embodiments, the normal angle refers to the angle at which the swing blades are normally located in the shutdown state, and the middle deviation angle range refers to the normal angle of the swing blades ± A degrees.

[0071] Of course, when the control modes of the swing blades of the air conditioning device are different, the normal angle and the angles within the middle deviation angle range can be adjusted according to the different control modes. Among them, the different control modes are mainly the differences in the air outlet directions. For example, leftward air outlet, middle air outlet, rightward air outlet, and swinging air outlet.

[0072] In some embodiments, in the leftward air outlet control mode, the normal angle refers to the angle of θ1 degrees between the swing blades and the connecting rod of the connecting rod mechanism in the shutdown state, where θ1 < 90 degrees. The middle deviation angle range refers to θ1 degrees ± A degrees.

[0073] In the middle air outlet control mode, the normal angle refers to the angle of 90 degrees between the swing blades and the connecting rod of the connecting rod mechanism in the shutdown state. The middle deviation angle range refers to 90 degrees ± A degrees.

[0074] In the rightward air outlet control mode, the normal angle refers to the angle of θ2 degrees between the swing blades and the connecting rod of the connecting rod mechanism in the shutdown state, where θ2 > 90 degrees. The middle deviation angle range refers to θ2 degrees ± A degrees.

[0075] In the swinging air outlet control mode, the normal angle refers to the angle of 90 degrees between the swing blades and the connecting rod of the connecting rod mechanism in the shutdown state. The middle deviation angle range refers to 90 degrees ± A degrees.

[0076] In some embodiments, in all control modes, the normal angle in the shutdown state can also be that the swing blades and the connecting rod of the connecting rod mechanism are at 90 degrees. The middle deviation angle range refers to 90 degrees ± A degrees.

[0077] When the air conditioning device is operating, it receives the control instruction of the swing blade assembly and operates according to the control mode corresponding to the control instruction. When the air conditioning device is shut down, the normal angle at which the swing blades are located in the shutdown state is obtained according to the control mode. The swing blade angle detection module detects the angles of the middle area swing blades, the first side area swing blades, and the second side area swing blades in the shutdown state, reads the adjustable angle range and the alarm angle range of the middle area swing blades, the first side area swing blades, and the second side area swing blades stored in the storage module. When the detected angle is within the adjustable angle range, the swing blade angle is adjusted; when the detected angle is within the alarm angle range, an alarm message is output.

[0078] This embodiment also proposes a control method for an air conditioner device. The control method includes: When the air conditioner is turned off, detect the angles of the middle area louver, the first side area louver, and the second side area louver. Obtain the adjustable angle range and the alarm angle range. When the detected angle is within the adjustable angle range, adjust the louver angle. When the detected angle is within the alarm angle range, output an alarm message.

[0079] Therefore, the air conditioner device can automatically identify the deviation of the louver angle and make automatic adjustment or give an alarm according to the deviation, so as to correct the louver deviation in time and ensure that the air outlet direction meets the user's needs.

[0080] Detect the angles of the middle area louver, the first side area louver, and the second side area louver in the shutdown state through the louver angle detection module.

[0081] In some embodiments, the louver angle detection module is a camera or a radar device provided at or near the air outlet of the air conditioner device.

[0082] In some embodiments, there is 1 louver angle detection module, which is opposite to the middle area louver.

[0083] In some embodiments, there are 3 louver angle detection modules, which are respectively opposite to the middle area louver, the first side area louver, and the second side area louver. The detection accuracy can be improved.

[0084] Store the adjustable angle range and the alarm angle range of the middle area louver, the first side area louver, and the second side area louver in the shutdown state through the storage module.

[0085] In some embodiments, the adjustable angle range is as follows: the deviation directions of the middle area louver, the first side area louver, and the second side area louver are the same; the deviation directions of at least two of the middle area louver, the first side area louver, and the second side area louver are the same and the deviation angle of the middle area louver is not the maximum among the three.

[0086] The deviation directions of the middle area louver, the first side area louver, and the second side area louver are the same. This situation may be due to the fact that the louvers in the three areas do not return to the correct position at the same time. In this case, the angle adjustment is carried out first.

[0087] The deviation directions of at least two of the middle area louver, the first side area louver, and the second side area louver are the same and the deviation angle of the middle area louver is not the maximum among the three. This situation may be due to the fact that the louvers in the three areas do not return to the correct position at the same time. In this case, the angle adjustment is carried out first.

[0088] In some embodiments, the alarm angle range is as follows: when the middle area swing blade is outside the middle deviation angle range, the deviation angle of the middle area swing blade is the maximum among the three; when the middle area swing blade is within the middle deviation angle range, both the first side area swing blade and the second side area swing blade are outside the side deviation angle range.

[0089] Wherein, the side deviation angle is greater than the middle deviation angle.

[0090] In some embodiments, in the shutdown state, the swing blade and the connecting rod of the connecting rod mechanism form an angle of θ degrees, the middle deviation angle range is θ degrees ± A degrees, and the measured deviation angle range is θ degrees ± B degrees, where B > A.

[0091] When the middle area swing blade is outside the middle deviation angle range and the deviation angle of the middle area swing blade is the maximum among the three; this situation indicates that the deviation angle of the middle area swing blade is greater than the deviation angles of the first side area swing blade and the second side area swing blade, indicating a situation that requires maintenance, and an alarm message is output.

[0092] When the middle area swing blade is within the middle deviation angle range and both the first side area swing blade and the second side area swing blade are outside the side deviation angle range, it indicates that the middle area swing blade is normal, and both the first side area swing blade and the second side area swing blade are abnormal, indicating a situation that requires maintenance, and an alarm message is output.

[0093] To improve the alarm accuracy and avoid false alarms, when the detected angles are within the alarm range during multiple shutdown state detections, an alarm message is output.

[0094] In some embodiments, the average deviation angle of the middle area swing blade, the average deviation angle of the first side area swing blade, and the average deviation angle of the second side area swing blade in the shutdown state are determined; and they are compared with the angle range stored in the storage module.

[0095] In some embodiments, the maximum deviation angle of the middle area swing blade, the maximum deviation angle of the first side area swing blade, and the maximum deviation angle of the second side area swing blade in the shutdown state are determined; and they are compared with the angle range stored in the storage module.

[0096] In some embodiments, the deviation angle of the middle swing blade of the middle area swing blade, the deviation angle of the middle swing blade of the first side area swing blade, and the deviation angle of the middle swing blade of the second side area swing blade in the shutdown state are determined, and the deviation angles of the middle swing blades of the three areas are compared with the angles stored in the storage module.

[0097] When the detected angle is within the adjustable angle range, the middle area swing blade is driven by a driving motor to be adjusted within the middle deviation angle range or to a normal angle.

[0098] In some embodiments, the storage module stores the number of driving motor steps corresponding to the deviation angle of the middle area swing blade to the normal angle. By controlling the driving motor to rotate the corresponding number of steps, the middle area swing blade is driven to be adjusted to within the middle deviation angle range or the normal angle.

[0099] In some embodiments, the middle area swing blade is driven by a driving motor, and the swing blade angle detection module is used to detect whether the middle area swing blade is adjusted to within the middle deviation angle range or the normal angle. When the middle area swing blade is adjusted to within the middle deviation angle range or the normal angle, the driving motor is controlled to stop operating; otherwise, the adjustment continues.

[0100] In some embodiments, the normal angle refers to the angle at which the swing blade is normally located in the shutdown state, and the middle deviation angle range refers to the normal angle of the swing blade ± A degrees.

[0101] Of course, when the control modes of the swing blades of the air conditioner device are different, the normal angle and the angle within the middle deviation angle range can be adjusted according to the different control modes. Among them, the different control modes are mainly the differences in the air outlet directions. For example, left air outlet, middle air outlet, right air outlet, and swinging air outlet.

[0102] In some embodiments, in the left air outlet control mode, the normal angle refers to the angle of θ1 degrees between the swing blade and the connecting rod of the connecting rod mechanism in the shutdown state, where θ1 < 90 degrees. The middle deviation angle range refers to θ1 degrees ± A degrees.
