Description

Technical Field

[0001] The present invention relates to the technical field of household appliance manufacturing, and in particular to a control method for an air deflector of an air conditioner and a control device for the air deflector of an air conditioner applicable to the control method. Background Art

[0002] In the related art, two air deflectors are provided at the air outlet of the air conditioner to selectively block the air outlet by driving the two air deflectors. Among them, the air deflector is power-connected to the rack on the driving motor through a connecting rod so that the two air deflectors can be driven to move when the driving motor rotates. However, since the movement trajectories of the air deflectors and the rack are different, and in the prior art, the driving motors corresponding to the two air deflectors use the same rotation speed to drive and control the two air deflectors. As a result, during the movement of the two air deflectors, it is very easy to have the problem that the width between the two air deflectors changes unpredictably, which not only affects the external appearance of the air conditioner for users, but also the air outlet effect is unstable, and the user experience is poor, so there is room for improvement.

[0037] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings, where 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 drawings are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0038] Reference will be made below to Figures 1 - 15 Describe the control method of the air deflector of the air conditioner according to the embodiments of the present invention. This control method can be used to realize the switching of the single-side air outlet state of the air conditioner 100, and when the air conditioner 100 is switched from other air outlet states to the single-side air outlet state, it is ensured that the two air deflectors 7 can move synchronously, and the problem of variable gap width between the two air deflectors 7 will not occur, which is beneficial to improving the external appearance of the air conditioner 100, ensuring a relatively stable air outlet effect, and enhancing the user experience.

[0039] Among them, the housing of the air conditioner 100 to which this control method is applicable has an air outlet 9, and the air outlet 9 can be provided on the front panel of the air conditioner 100 and the air outlet 9 faces forward and is open. As Figures 1 - 6As shown in the figure, the housing may include a top cover 1 and a bottom cover 2. Two driving motors 3 are arranged on the top cover 1, and a driving gear 4 corresponding to the two driving motors 3 is installed between the top cover 1 and the top cover 1, as well as a rack 5 meshing with the two driving gears 4. A guide vane connecting rib 8 for connecting with the guide vane 7 is also provided between the top cover 1 and the bottom cover 2. Two guide vanes 7 are arranged at the air outlet 9. The two guide vanes 7 are respectively located in the left area and the right area inside the air outlet 9. The two guide vanes 7 are respectively connected to the corresponding racks 5 through two connecting rods 6, so that the two guide vanes 7 can move along the width direction of the air outlet 9 under the driving action of the driving motor 3. Among them, the air outlet plate on the left can reciprocate in the left area of the air outlet 9 to move from the outermost position in the left area of the air outlet 9 to the middle area of the air outlet 9 or further move to the right, or the right area moves towards the middle area and moves from the middle area to the outermost position in the left area of the air outlet 9. Similarly, the air outlet plate on the right can reciprocate in the right area of the air outlet 9 to move from the outermost position in the right area of the air outlet 9 to the middle area of the air outlet 9 or further move to the left, or the left area moves towards the middle area and moves from the middle area to the outermost position in the right area of the air outlet 9.

[0040] As Figures 1 - 6 shown, each guide vane 7 is correspondingly provided with a driving motor 3. Specifically, the output shaft of the driving motor 3 is provided with a driving gear 4, and the driving gear 4 is in meshing transmission with the rack 5. At the same time, the rack 5 is connected to the guide vane 7 through the connecting rod 6. In this way, when the driving motor 3 rotates, the rack 5 is driven to rotate by the driving gear 4, and the guide vane 7 is driven to move by the connecting rod 6 during the rotation of the rack 5. Among them, the movement track A1 of the rack 5 is an arc track, and the movement track A2 of the guide vane 7 is also constructed as an arc track. It should be noted that the curvature radius of the movement track A1 of the rack 5 is smaller than the curvature radius of the movement track A2 of the guide vane 7, and the center of the movement track A1 of the rack 5 and the center of the movement track A2 of the guide vane 7 are located on the symmetry line of the vertical projection of the air outlet 9, and the radii of the two movement tracks differ greatly.

[0041] As Figure 11 shown, the control method of the guide vane of the air conditioner according to the embodiment of the present invention includes:

[0042] S1: Obtain a single-side air outlet signal and the current air outlet state.

[0043] It should be noted that the control method of the present invention is applicable when the user needs to adjust the air outlet state of the air conditioner 100. The unilateral air outlet signal is obtained after the user outputs an operation instruction. For example, the user outputs an instruction to the air conditioner 100 through a remote controller, so that the air conditioner 100 can obtain the unilateral air outlet signal according to the user's input instruction. Among them, the unilateral air outlet signal includes a left air outlet signal and a right air outlet signal. That is, when the user needs to adjust the air outlet state of the air conditioner to the left air outlet state, the user can output the left air outlet signal to the air conditioner 100 through the remote controller, and when the user needs to adjust the air outlet state of the air conditioner 100 to the right air outlet state, the user can output the right air outlet signal to the air conditioner 100 through the remote controller.

[0044] Among them, the current air outlet state can be obtained through the control components built in the air conditioner 100, that is, the state information of the air outlet related structure can be obtained through the control components to obtain the current air outlet state, and the current air outlet state includes a left air outlet state, a right air outlet state, and other air outlet states. The other air outlet states can include the air outlet states set by the user himself. It can be understood that the current air outlet state can reflect the actual air outlet direction.

[0045] S2: Determine whether the current air outlet state corresponds to the unilateral air outlet signal. That is to say, after obtaining the unilateral air outlet signal and the current air outlet state, the target air outlet state corresponding to the unilateral air outlet signal can be compared with the current air outlet state to determine whether the current air outlet state is consistent with the air outlet state required by the user, so as to perform corresponding operations to meet the user's air outlet requirements.

[0046] Specifically, when the unilateral air outlet signal input by the user is the left air outlet signal and the current air outlet state is the left air outlet state, it is determined that the current air outlet state corresponds to the unilateral air outlet signal, that is, the current air outlet state already meets the user's air outlet requirements; when the unilateral air outlet signal input by the user is the left air outlet signal and the current air outlet state is the right air outlet state or other air outlet states, it is determined that the current air outlet state does not correspond to the unilateral air outlet signal. At this time, control operations need to be performed to make the air outlet state of the air conditioner 100 meet the user's requirements. Or when the unilateral air outlet signal input by the user is the right air outlet signal and the current air outlet state is the right air outlet state, it is determined that the current air outlet state corresponds to the unilateral air outlet signal, that is, the current air outlet state already meets the user's air outlet requirements; when the unilateral air outlet signal input by the user is the right air outlet signal and the current air outlet state is the left air outlet state or other air outlet states, it is determined that the current air outlet state does not correspond to the unilateral air outlet signal. At this time, control operations need to be performed to make the air outlet state of the air conditioner 100 meet the user's requirements.

[0047] S31: If not, control both air deflectors 7 to reset to the middle zero position, and then control the two air deflectors 7 to move synchronously according to the single-sided air outlet signal to switch to the target air outlet state corresponding to the single-sided air outlet signal.

[0048] That is to say, when it is determined that the current air outlet state does not correspond to the single-sided air outlet signal input by the user, control both air deflectors 7 to move to the middle zero position. For example, when the single-sided air outlet signal input by the user is the left air outlet signal and the current air outlet state is the right air outlet state or other air outlet states, control both air deflectors 7 to move to the middle position of the air outlet 9, that is, the two air deflectors 7 are arranged side by side in the middle of the air outlet 9 and there is no obvious gap between the two air deflectors 7; or when the single-sided air outlet signal input by the user is the right air outlet signal and the current air outlet state is the left air outlet state or other air outlet states, control both air deflectors 7 to move to the middle position of the air outlet 9, that is, the two air deflectors 7 are arranged side by side in the middle of the air outlet 9 and there is no obvious gap between the two air deflectors 7. In this way, after moving both air deflectors 7 to the middle position, this position can be used as the zero position for further controlling the movement of the air deflectors 7, that is, the initial position for further control.

[0049] Further, after both air deflectors 7 are in the middle position, further control the two air deflectors 7 according to the single-sided air outlet signal so that the two air deflectors 7 can move synchronously relative to the air outlet 9. For example, when the single-sided air outlet signal is the left air outlet signal, the two air deflectors 7 can be driven to move synchronously towards the right area in the air outlet 9 to block the right side of the air outlet 9, so that the left side of the air outlet 9 blows air. Or when the single-sided air outlet signal is the right air outlet signal, the two air deflectors 7 can be driven to move synchronously towards the left area in the air outlet 9 to block the left side of the air outlet 9, so that the right side of the air outlet 9 blows air. Thus, the adjustment of the air outlet state of the air conditioner 100 can be realized, that is, any current air outlet state can be adjusted to the target air outlet state to meet the user's air outlet requirements.

[0050] S32: If so, control the two air deflectors 7 to operate in the current air outlet state.

[0051] That is to say, when it is determined that the current air outlet state corresponds to the single-sided air outlet signal input by the user, there is no need to control and drive the air deflectors 7, that is, the air deflectors 7 can maintain the current state to meet the user's air outlet requirements. For example, when the single-sided air outlet signal is the left air outlet signal and the current air outlet state is the left air outlet state, or when the single-sided air outlet signal is the right air outlet signal and the current air outlet state is the right air outlet state, the user's air outlet requirements correspond to the current air outlet state, that is, there is no need to adjust the state of the air deflectors 7 to make the air conditioner 100 meet the user's air outlet requirements.

[0052] Thus, through the control method of the air deflector of the air conditioner according to the embodiments of the present application, when the user has a need for single-sided air outlet, the two air deflectors 7 can be controlled to move synchronously, ensuring that the two air deflectors 7 can move synchronously to the left side of the air outlet 9 or synchronously to the right side of the air outlet 9, so as to avoid the problem of air leakage gap between the two air deflectors 7. Therefore, it is beneficial to improve the external appearance perception of the air conditioner 100 by the user, ensure a relatively stable air outlet effect, and enhance the user experience.

[0053] In some embodiments, in step S31: Controlling the two air deflectors 7 to reset to the middle zero position includes: first controlling the two air deflectors 7 to move from the current position to the maximum side zero positions on both sides of the air outlet 9 respectively; then controlling the two air deflectors 7 to move from the maximum side zero positions on both sides to the middle zero position.

[0054] That is to say, the two air deflectors 7 in the present application perform two reset operations in sequence when resetting, that is, first drive the two air deflectors 7 to move away from each other, so that the two air deflectors 7 move to the two side walls of the air outlet 9 respectively, avoiding the problem of interference between the two air deflectors 7. That is, when it is determined that the single-sided air outlet signal does not correspond to the current air outlet state, as Figure 7 shown, the driving motors 3 corresponding to the two air deflectors 7 rotate in opposite directions respectively, such as one driving motor 3 rotates counterclockwise and the other driving motor 3 rotates clockwise, to drive the air deflector 7 on the left side to move to the leftmost side, and at the same time drive the air deflector 7 on the right side to move to the rightmost side, so that the two air deflectors 7 are both located at the first zero position.

[0055] Further, after the two air deflectors 7 are both located at the first zero position, taking this as the basic position for movement, drive the two air deflectors 7 to move towards the middle area, that is, as Figure 8 shown, the driving motors 3 corresponding to the two air deflectors 7 can be controlled to rotate in opposite directions, to drive the air deflector 7 on the left side to move to the right to the middle position, and at the same time drive the air deflector 7 on the right side to move to the left to the middle position, so that the two air deflectors 7 are both located at the second zero position. It should be noted that the rotation direction of the driving motor 3 this time is opposite to the rotation direction during the adjustment of the first zero position. Thus, it can be ensured that both zero positions can be accurately and reliably achieved. It can be understood that when the speeds of the two air deflectors 7 are different and they move together, there will be a mutual acting force between the air deflectors 7. At this time, the movement position of the air deflector 7 and the number of steps of the motor movement are not a clear corresponding relationship. In the present application, this problem can be effectively solved through the reset operation.

[0056] In some embodiments, when the single-sided air outlet signal is a left-side air outlet signal, controlling the two air deflectors 7 to move synchronously with the left-side air outlet signal to switch to the target air outlet state corresponding to the single-sided air outlet signal includes:

[0057] The two air deflectors 7 are controlled separately, that is, the driving motors 3 corresponding to the two air deflectors 7 rotate at different speeds respectively. Specifically, the driving motor 3 corresponding to the air deflector 7 on the left side can be controlled to rotate at the first speed, and when the driving motor 3 rotates at the first speed, the driving motor drives the air deflector 7 on the left side to move to the right; at the same time, the driving motor 3 corresponding to the air deflector 7 on the right side is controlled to rotate at the second speed, and when the driving motor 3 rotates at the second speed, the driving motor 3 drives the air deflector 7 on the right side to also move to the right. Thus, the air outlet state of the air conditioner 100 can be switched from the current air outlet state to the left air outlet state, where the first speed is greater than the second speed.

[0058] It can be understood that the two air deflectors 7 are both power-connected to the driving motor 3 through the connecting rod 6 and the rack 5, and the conversion rate between the rotation speed of the driving motor 3 and the movement speed of the air deflector 7 is smaller when the air deflector 7 is closer to the middle of the air outlet 9, while the conversion rate between the rotation speed of the driving motor 3 and the movement speed of the air deflector 7 is larger when the air deflector 7 is closer to the two sides of the air outlet 9, that is, at the same rotation speed of the driving motor 3, the movement amount of the air deflector 7 at the middle position is smaller than the movement amount of the air deflector 7 at the two side positions.

[0059] Thus, when the user switches the current air outlet state of the air conditioner 100 to the left air outlet state, both the air deflector 7 on the left side and the air deflector 7 on the right side move to the right, and the air deflector 7 on the left side gradually moves towards the middle position of the air outlet 9, while the air deflector 7 on the right side gradually moves away from the middle position of the air outlet 9, that is, at the same rotation speed of the driving motor 3, the movement speed of the air deflector 7 on the left side is smaller than the movement speed of the air deflector 7 on the right side. In this application, by setting the first speed to be greater than the second speed, after the two driving motors 3 drive the two air deflectors 7 at the first speed and the second speed respectively, the movement speed of the air deflector 7 on the left side is not less than the movement speed of the air deflector 7 on the right side. In this way, the two air deflectors 7 on the left side can always fit with the air deflector 7 on the right side, thereby avoiding gaps between the two air deflectors 7. Thus, it is beneficial to improve the external appearance of the air conditioner 100, ensure a relatively stable air outlet effect, and enhance the user experience.

[0060] In some embodiments, the first speed is the maximum speed that the driving motor 3 corresponding to the air deflector 7 on the left side can achieve during rotation, and the second speed is the minimum speed that the driving motor 3 corresponding to the air deflector 7 on the right side can achieve during rotation. In this way, the first speed can be significantly greater than the second speed.

[0061] It can be understood that when the two driving motors 3 drive the two air deflector plates 7 to move towards the right respectively, by setting the moving speed of the air deflector plate 7 on the right to be less than the moving speed of the air deflector plate 7 on the left, the right side surface of the air deflector plate 7 on the left can always be attached to the left side surface of the air deflector plate 7 on the right. Therefore, by selecting the maximum value and the minimum value corresponding to the two driving motors 3 for the first rotational speed and the second rotational speed respectively, it can be ensured that the two air deflector plates 7 will not have an excessive speed difference and separate from each other to form an obvious gap, that is, to ensure the synchronous movement of the two air deflector plates 7, improve the external appearance of the air conditioner 100, ensure a relatively stable air outlet effect, and improve the user experience.

[0062] Among them, in combination with Figure 13 Describe the control logic executed when switching to the left air outlet state in the embodiments of the present application. First, the user switches the left air outlet state at the remote control end, that is, obtains the left air outlet signal, and further determines whether the left air outlet state was before the button press. If so, the air deflector plate 7 maintains the current operation; if not, control the air deflector plate 7 to reset, that is, the two air deflector plates 7 first move to the first zero position, and then move to the second zero position. Further, control the driving motor 3 on the left to rotate at the first rotational speed, and the driving motor 3 on the right to rotate at the second rotational speed. After the control of the air deflector plate 7 is completed, confirm whether to change the air outlet mode. If not, maintain the current operation. If so, control the air deflector plate 7 to reset to switch to other corresponding modes.

[0063] In some embodiments, when the single-sided air outlet signal is the right air outlet signal, controlling the two air deflector plates 7 to move synchronously to switch to the target air outlet state corresponding to the single-sided air outlet signal includes:

[0064] Control the two air deflector plates 7 respectively, that is, the driving motors 3 corresponding to the two air deflector plates 7 rotate at different rotational speeds for control respectively. Specifically, the driving motor 3 corresponding to the air deflector plate 7 located on the right can be controlled to rotate at the third rotational speed, and when the driving motor 3 rotates at the third rotational speed, the driving motor drives the air deflector plate 7 on the right to move leftward; at the same time, control the driving motor 3 corresponding to the air deflector plate 7 located on the left to rotate at the fourth rotational speed, and when the driving motor 3 rotates at the fourth rotational speed, the driving motor 3 drives the air deflector plate 7 on the left to also move leftward. Thus, the air outlet state of the air conditioner 100 can be switched from the current air outlet state to the right air outlet state, where the third rotational speed is greater than the fourth rotational speed.

[0065] Similarly, as described above, at the same rotational speed of the driving motor 3, the movement amount of the air deflector plate 7 at the middle position is less than the movement amount of the air deflector plates 7 at the two side positions.

[0066] Thus, when the user switches the current air outlet state of the air conditioner 100 to the right air outlet state, the right air deflector 7 and the left air deflector 7 both move towards the left, and the right air deflector 7 gradually moves towards the center position of the air outlet 9, while the left air deflector 7 gradually moves away from the center position of the air outlet 9, that is, the movement speed of the right air deflector 7 is less than that of the left air deflector 7 at the same rotational speed of the driving motor 3. In this application, by setting the third rotational speed to be greater than the fourth rotational speed, after the two driving motors 3 drive the two air deflectors 7 at the third rotational speed and the fourth rotational speed respectively, the movement speed of the right air deflector 7 is not less than that of the left air deflector 7. In this way, the two right air deflectors 7 can always fit with the left air deflector 7, thereby avoiding gaps between the two air deflectors 7. Thus, it is beneficial to improve the external appearance of the air conditioner 100, ensure a relatively stable air outlet effect, and enhance the user experience.

[0067] In some embodiments, the third rotational speed is the maximum rotational speed that the driving motor 3 corresponding to the right air deflector 7 can achieve during rotation, and the fourth rotational speed is the minimum rotational speed that the driving motor 3 corresponding to the left air deflector 7 can achieve during rotation. In this way, the third rotational speed can be significantly greater than the fourth rotational speed. It should be noted that the first rotational speed in this application can be set to be the same as the third rotational speed, and the second rotational speed can be set to be the same as the fourth rotational speed.

[0068] It can be understood that when the two driving motors 3 drive the two air deflectors 7 to move towards the left respectively, by setting the movement speed of the left air deflector 7 to be less than that of the right air deflector 7, the left side surface of the right air deflector 7 can always fit with the right side surface of the left air deflector 7. Therefore, by selecting the maximum and minimum values corresponding to the two driving motors 3 for the third rotational speed and the fourth rotational speed respectively, it can be ensured that there will be no problem that the movement speeds of the two air deflectors 7 are too different and they separate from each other to form an obvious gap, that is, to ensure the movement synchronization of the two air deflectors 7, improve the external appearance of the air conditioner 100, ensure a relatively stable air outlet effect, and enhance the user experience.

[0069] Among them, combining Figure 14 Describe the control logic executed when switching to the right air outlet state in the embodiments of this application. First, the user switches the right air outlet state at the remote control end, that is, obtains the right air outlet signal, and further determines whether the right air outlet state was in effect before the button press. If so, the air deflector 7 maintains the current operation; if not, control the air deflector 7 to reset, that is, the two air deflectors 7 first move to the first zero position, then move to the second zero position. Further, control the right driving motor 3 to rotate at the third rotational speed, and the left driving motor 3 to rotate at the fourth rotational speed. After the control of the air deflector 7 is completed, confirm whether to change the air outlet mode. If not, maintain the current operation. If so, control the air deflector 7 to reset to switch to other corresponding modes.

[0070] Therefore, in the present application, through the control method of the above steps, when the air conditioner 100 switches to the left air outlet state and the right air outlet state, the two air deflector plates 7 can move synchronously, ensuring the consistency of the movement of the air deflector plates 7 to avoid obvious gaps. At the same time, it should be noted that the air conditioner 100 in the present application can not only achieve the left air outlet state and the right air outlet state, but also the three-side air outlet state. Among them, in the three-side air outlet state, the air deflector plate 7 on the left is located in the middle of the left area inside the air outlet 9, and the air deflector plate 7 on the right is located in the middle of the right area inside the air outlet 9. That is, the air deflector plate 7 on the left is spaced apart from the left side wall of the air outlet 9 to form a left air outlet area, the air deflector plate 7 on the right is spaced apart from the right side wall of the air outlet 9 to form a right air outlet area, and the two air deflector plates 7 are spaced apart to form an intermediate air outlet area in the middle of the air outlet 9. Thus, the three-side air outlet state can be achieved, ensuring that cold air supply can be enjoyed in three different areas of the space.

[0071] And it should be noted that when the air conditioner 100 in the present application is in the three-side air outlet state, the two air deflector plates 7 can move relative to the side wall of the air outlet 9 at the same time, that is, the two air deflector plates 7 can reciprocate inside the air outlet 9, so as to achieve the reciprocating air-sweeping mode.

[0072] Furthermore, the control method of some embodiments of the present invention further includes:

[0073] S41: Obtain the air-sweeping signal for three-side air outlet. Among them, obtaining the air-sweeping signal for three-side air outlet is obtained after the user outputs an operation instruction. For example, the user outputs an instruction to the air conditioner 100 through the remote control, so that the air conditioner 100 can obtain the air-sweeping signal for three-side air outlet according to the user's input instruction. Among them, when the user needs to adjust the air outlet state of the air conditioner to the three-side air outlet state and continuously sweep the air, the air-sweeping signal for three-side air outlet can be output to the air conditioner 100 through the remote control.

[0074] S42: Control the two air deflectors 7 to move to the three-side air outlet state. Among them, moving the two air deflectors 7 to the three-side air outlet state includes that the current air outlet state is the three-side air outlet state and the current air outlet state is not the three-side air outlet state. And when the current air outlet state is the three-side air outlet state, the air deflector 7 remains in the current position; while when the current air outlet state is not the three-side air outlet state, such as the left-side air outlet state, control the two air deflectors 7 to move leftward, and the air deflector 7 on the left side moves leftward with a greater amplitude than the air deflector 7 on the right side, so that the two air deflectors 7 move to the middle positions of the left and right regions of the air outlet 9 respectively, that is, a three-side air outlet gap is formed. Or when the current state is the right-side air outlet state, control the two air deflectors 7 to move rightward, and the air deflector 7 on the right side moves rightward with a greater amplitude than the air deflector 7 on the left side, so that the two air deflectors 7 move to the middle positions of the left and right regions of the air outlet 9 respectively, that is, a three-side air outlet gap is formed. Thus, the air conditioner 100 can be switched to the three-side air outlet state.

[0075] S43: Divide the movement trajectory A2 of the air deflector 7 into multiple reference distances equally, and obtain the target rotational speeds of the driving motors 3 corresponding to the two air deflectors 7 according to the reference distances.

[0076] That is to say, after the positions of the two air deflectors 7 are fixed and the three-side air outlet area is formed, the movement trajectory A2 of the air deflector 7 is divided equally in length. Among them, the length of the reference distance can be selectively set according to actual needs, and each reference distance is the equal division length of the movement of the two air deflectors 7, so as to determine the target rotational speeds of the driving motors 3 corresponding to the air deflectors 7 according to the reference distance, and ensure that the two air deflectors 7 can move synchronously.

[0077] S44: Control the two driving motors 3 to rotate at the corresponding target rotational speeds so that the two air deflectors 7 reciprocate synchronously.

[0078] It can be understood that each air deflector 7 in the present application is power-connected to the rack 5 at the corresponding drive motor 3 through a connecting rod 6. Among them, the structure of the air deflector 7 is determined, the length value of the connecting rod 6 is determined, and the structures of the gear on the drive motor 3 and the rack 5 are determined. As a result, the movement trajectory A1 of the rack 5 and the movement trajectory A2 of the air deflector 7 are determined. That is to say, after the movement amount of the air deflector 7 within the reference distance is determined, the target rotational speeds of the drive motor 3 corresponding to the reference distances at multiple different positions along the movement trajectory of the air deflector 7 can be obtained through the movement trajectory A2 of the air deflector 7, the length value of the connecting rod 6, the movement trajectory A1 of the rack 5, and the structural characteristics between the driving gear 4 and the rack 5. Thus, by controlling the drive motor 3 at the target rotational speed, in this way, it can be ensured that during the air-sweeping movement, each air deflector 7 can complete the movement of the reference distance within a specific time period, so as to ensure that the two air deflectors 7 can move synchronously, keep the gap between the two air deflectors 7 basically unchanged, and further avoid the problem of the change in the distance between the two air deflectors 7, which is beneficial to improving the external visual perception of the air conditioner 100 by the user, ensuring a relatively stable air outlet effect, and enhancing the user experience.

[0079] In some embodiments, in step S43, obtaining the target rotational speeds of the drive motors 3 corresponding to the two air deflectors 7 according to the reference distance includes: First, a reference circle is drawn at each equal division point of the movement trajectory A2 of the air deflector 7, and the radius of the reference circle at each equal division point is the length of the connecting rod 6. After the reference circle is drawn, the points where the reference circle intersects with the movement trajectory A1 of the rack 5 are the movement base points corresponding one by one to the equal division points on the movement trajectory A2 of the air deflector 7. And the respective reference lengths of the movement trajectory A1 of the rack 5 can be determined according to the points where the reference circle intersects with the movement trajectory A1 of the rack 5, that is, the distance between two movement base points is the reference length of the movement distance of the rack 5 within a specific time period. Furthermore, the respective target rotational speeds corresponding to the drive motor 3 can be obtained according to each reference length.

[0080] It can be understood that after the reference distance of the movement trajectory A2 of the air deflector 7 is determined, every specific time period, the movement distance of the air deflector 7 is the reference distance. Similarly, after the reference lengths of the movement of the rack 5 within each specific time period are determined corresponding to the reference distance, the rotational speed corresponding to the drive motor 3 can be determined through the radius of the gear. Thus, after the rotational speeds of the drive motors 3 corresponding to the two air deflectors 7 are controlled at the above rotational speeds, it can be ensured that the movement distances of the two air deflectors 7 within a specific time period are the same, that is, it can be ensured that the two air deflectors 7 can move synchronously, and the problem of the indefinite change in the distance between the two air deflectors 7 can be solved.

[0081] Among them, it should be noted that the two air guide plates 7 are respectively located on the first side and the second side inside the air outlet 9, and one of the first side and the second side is the left side and the other is the right side. That is to say, one of the two air guide plates 7 can be the left air guide plate 7, and the other is the right air guide plate 7. Among them, in the air-sweeping state, both of the two air guide plates 7 start from the initial position of the three-side air outlet state and first move synchronously to the right, and then move to the left, so as to achieve left-right reciprocation. Or both of the two air guide plates 7 start from the initial position of the three-side air outlet state, first move synchronously to the left, and then move to the right, so as to achieve left-right reciprocation.

[0082] Therefore, in some embodiments, when controlling the two drive motors 3, the two drive motors 3 can be controlled to rotate at corresponding target speeds so that the two air guide plates 7 reciprocate synchronously, including the control of the drive motor 3 corresponding to one of the air guide plates 7 and the control of the drive motor 3 corresponding to the other air guide plate 7.

[0083] Among them, when controlling the drive motor 3 corresponding to one air guide plate 7, the drive motor 3 can be controlled to first rotate at the a1 speed, then rotate at the a2 speed,..., and then rotate at the aI speed, so as to drive the one air guide plate 7 to move from the initial position of the three-side air outlet along the direction close to the first side to the direction close to the second side; at the same time, when controlling the drive motor 3 corresponding to the other air guide plate 7, the drive motor 3 can be controlled to first rotate at the b1 speed, then rotate at the b2 speed,..., and then rotate at the bI speed, so as to drive the other air guide plate 7 to move from the initial position of the three-side air outlet along the direction close to the first side to the direction close to the second side.

[0084] It should be noted that when the two air guide plates 7 in the present application both move from the first side towards the second side, the above control method can be executed: for example, when the two air guide plates 7 both move from the left side to the right side, the driving motor 3 corresponding to the left air guide plate 7 rotates at the a1 speed, then at the a2 speed,..., and then rotates step by step at the ai speed to make the left air guide plate 7 move to the right. The driving motor 3 corresponding to the right air guide plate 7 rotates at the b1 speed, then at the b2 speed,..., and then rotates at the bi speed, also making the right air guide plate 7 move to the right, so that the left air guide plate 7 and the right air guide plate 7 move to the right synchronously; or when the two air guide plates 7 both move from the right side to the left side, the driving motor 3 corresponding to the right air guide plate 7 rotates at the a1 speed, then at the a2 speed,..., and then rotates step by step at the ai speed to make the right air guide plate 7 move to the left. The driving motor 3 corresponding to the left air guide plate 7 rotates at the b1 speed, then at the b2 speed,..., and then rotates at the bi speed, also making the left air guide plate 7 move to the left, so that the right air guide plate 7 and the left air guide plate 7 move to the left synchronously, thereby realizing the left-right reciprocating movement of the two air guide plates 7 at the air outlet 9.

[0085] The following is described with reference to the attached Figure 10 Taking the case where the two air guide plates 7 both move from left to right as an example, first, the motion trajectory A2 of the air guide plate 7 is equally divided into several (k) benchmark distances L0 (it should be noted to reserve the arc length part of the interval between the ribs of the two air guide plates 7). Secondly, a reference circle with a fixed length of the connecting rod 6 is made at the equal division points of the motion trajectory A2 of the air guide plate 7. By the intersection of the reference circle and the motion trajectory A1 of the rack 5, the reference length of the motion interval of the rack 5 corresponding to the left air guide plate 7 can be found when the left air guide plate 7 moves to the right while maintaining a uniform motion. Similarly, the reference length of the motion interval of the rack 5 corresponding to the right air guide plate 7 is also shown in the figure. Among them, the first section of the path of the right air guide plate 7 is the reference L1.r (such as a length of 7.01). Determine the number of steps a1.r and the speed v1.r (the b1 speed) required for the driving motor 3 corresponding to the right air guide plate 7 to rotate at this time. The first section of the path of the left air guide plate 7 is the reference L1.l (such as a length of 7.18). Determine the number of steps a1.l required for the driving motor 3 corresponding to the right air guide plate 7 to rotate at this time, and the speed v1.l, where v1.l = v1.r * L1.l / L1.r, a1.l = a1.r * L1.l / L1.r. Such as Figure 10As shown, the motion references of the rack 5 corresponding to the air deflector 7 on the left are successively the first section L1.l (such as a length of 7.18), the second section L2.l (such as a length of 7.58), and the first section L3.l (such as a length of 7.98). The motion references of the rack 5 corresponding to the air deflector 7 on the left are successively the first section L1.r (such as a length of 7.01), the second section L2.r (such as a length of 5.87), and the first section L3.r (such as a length of 3.6).

[0086] It should be noted that the speed and the deployment of the motion using this speed at any position during the process of the two drive motors 3 turning to the right can be expressed as vi.l = v1.r * Li.l / L1.r, vi.r = v1.r * Li.r / L1.r, ai.l = a1.r * Li.l / L1.r, and ai.r = a1.r * Li.r / L1.r. The control flow chart adopted at this time is as Figure 15 shown (taking the air deflector 7 moving to the right in the Figure 9 state as an example, the method of moving to the left is similar and will not be elaborated here. At the same time, after the motion roadbed of the air deflector 7 is equally divided, the corresponding segmented situations of the left rack 5 and the right rack 5 are related to the design of the motion mechanism. When the motion mechanism is determined, the corresponding relationship of the segmented situations is determined).

[0087] Among them, the sweeping control logic in the three - side air - outlet state is as Figure 15 shown. After the user issues a sweeping control signal in the three - side air - outlet state, the air deflector 7 reaches the three - side air - outlet position and starts to move to the right. Among them, the rotation speed of the left - hand drive motor 3 can be controlled to be v1.l and the number of steps to be a1.l, the rotation speed of the right - hand drive motor 3 to be v1.r and the number of steps to be a1.r, and further, the rotation speed of the left - hand drive motor 3 to be v2.l and the number of steps to be a2.l, the rotation speed of the right - hand drive motor 3 to be v2.r and the number of steps to be a2.r,..., until the rotation speed of the left - hand drive motor 3 is vi.l and the number of steps is ai.l, the rotation speed of the right - hand drive motor 3 is vi.r and the number of steps is ai.r,..., and further, the rotation speed of the left - hand drive motor 3 is vk.l and the number of steps is ak.l, the rotation speed of the right - hand drive motor 3 is vk.r and the number of steps is ak.r. In this way, the two air deflectors 7 can move synchronously to the right to the maximum position, and after moving to the maximum position, the two air deflectors 7 are controlled to move in the reverse direction, so as to realize the sweeping operation of the two air deflectors 7.

[0088] This application also proposes a control device for the air deflector of an air conditioner.

[0089] The control device of the air deflector of the air conditioner according to an embodiment of the present invention is applicable to the control method of the air deflector of the air conditioner in any of the above embodiments, and includes: an acquisition module, a judgment module, and a control module. Among them, the acquisition module, the judgment module, and the control module are electrically connected. The information acquired by the acquisition module can be sent to the judgment module. The judgment module may be integrated with a judgment mechanism and is used to judge the information acquired by the acquisition module based on the judgment mechanism, and send the judgment result to the control module, so that the control module can execute corresponding control steps, thereby realizing the switching of the corresponding air outlet state.

[0090] The acquisition module is used to acquire the single-sided air outlet signal and the current air outlet state. Specifically, when the user needs to adjust the air outlet state of the air conditioner 100, the single-sided air outlet signal is acquired after the user outputs an operation instruction. For example, when the user outputs an instruction to the air conditioner 100 through the remote control, the air conditioner 100 can acquire the single-sided air outlet signal according to the user's input instruction. Among them, the single-sided air outlet signal includes the left air outlet signal and the right air outlet signal. That is, when the user needs to adjust the air outlet state of the air conditioner to the left air outlet state, the user can output the left air outlet signal to the air conditioner 100 through the remote control, and when the user needs to adjust the air outlet state of the air conditioner 100 to the right air outlet state, the user can output the right air outlet signal to the air conditioner 100 through the remote control.

[0091] The current air outlet state can be acquired by the control element built in the air conditioner 100, that is, the current air outlet state can be acquired by acquiring the state information of the air outlet-related structure through the control element. The current air outlet state includes the left air outlet state, the right air outlet state, and other air outlet states. Other air outlet states may include the air outlet states set by the user. It can be understood that the current air outlet state can reflect the actual air outlet direction.

[0092] The judgment module is used to judge whether the current air outlet state corresponds to the single-side air outlet signal. After obtaining the single-side air outlet signal and the current air outlet state, the target air outlet state corresponding to the single-side air outlet signal can be compared with the current air outlet state to determine whether the current air outlet state is consistent with the air outlet state required by the user, so as to perform corresponding operations to meet the user's air outlet requirements. Specifically, when the single-side air outlet signal input by the user is the left-side air outlet signal and the current air outlet state is the left-side air outlet state, it is judged that the current air outlet state corresponds to the single-side air outlet signal, that is, the current air outlet state has met the user's air outlet requirements; when the single-side air outlet signal input by the user is the left-side air outlet signal and the current air outlet state is the right-side air outlet state or other air outlet states, it is judged that the current air outlet state does not correspond to the single-side air outlet signal, and at this time, a control operation needs to be performed to make the air outlet state of the air conditioner 100 meet the user's requirements. Or when the single-side air outlet signal input by the user is the right-side air outlet signal and the current air outlet state is the right-side air outlet state, it is judged that the current air outlet state corresponds to the single-side air outlet signal, that is, the current air outlet state has met the user's air outlet requirements; when the single-side air outlet signal input by the user is the right-side air outlet signal and the current air outlet state is the left-side air outlet state or other air outlet states, it is judged that the current air outlet state does not correspond to the single-side air outlet signal, and at this time, a control operation needs to be performed to make the air outlet state of the air conditioner 100 meet the user's requirements

[0093] The control module is used to control both air deflector plates 7 to reset to the middle zero position when the judgment result is negative, and then control both air deflector plates 7 to move synchronously to switch to the target air outlet state corresponding to the single-side air outlet signal, and is used to control both air deflector plates 7 to maintain the current air outlet state when the judgment result is positive. That is to say, when it is judged that the current air outlet state does not correspond to the single-side air outlet signal input by the user, both air deflector plates 7 are controlled to move to the middle zero position. For example, when the single-side air outlet signal input by the user is the left-side air outlet signal and the current air outlet state is the right-side air outlet state or other air outlet states, both air deflector plates 7 are controlled to move to the middle position of the air outlet 9, that is, both air deflector plates 7 are arranged side by side in the middle position of the air outlet 9 and there is no obvious gap between the two air deflector plates 7; or when the single-side air outlet signal input by the user is the right-side air outlet signal and the current air outlet state is the left-side air outlet state or other air outlet states, both air deflector plates 7 are controlled to move to the middle position of the air outlet 9, that is, both air deflector plates 7 are arranged side by side in the middle position of the air outlet 9 and there is no obvious gap between the two air deflector plates 7. In this way, after both air deflector plates 7 are moved to the middle position, this position can be used as the zero position for further controlling the movement of the air deflector plates 7, that is, the initial position for further control

[0094] Further, after both air deflectors 7 are in the middle position, further control the two air deflectors 7 according to the single-sided air outlet signal so that the two air deflectors 7 can move synchronously relative to the air outlet 9. For example, if the single-sided air outlet signal is a left air outlet signal, the two air deflectors 7 can be driven to move synchronously towards the right area in the air outlet 9 to block the right side of the air outlet 9, so that the left side of the air outlet 9 blows air. Or when the single-sided air outlet signal is a right air outlet signal, the two air deflectors 7 can be driven to move synchronously towards the left area in the air outlet 9 to block the left side of the air outlet 9, so that the right side of the air outlet 9 blows air. Thus, the adjustment of the air outlet state of the air conditioner 100 can be realized, that is, any current air outlet state can be adjusted to the target air outlet state to meet the air outlet needs of the user.

[0095] In addition, when it is determined that the current air outlet state corresponds to the single-sided air outlet signal input by the user, there is no need to control and drive the air deflector 7, that is, the air deflector 7 can maintain its current state to meet the air outlet needs of the user. For example, when the single-sided air outlet signal is a left air outlet signal and the current air outlet state is a left air outlet state, or when the single-sided air outlet signal is a right air outlet signal and the current air outlet state is a right air outlet state, the air outlet needs of the user correspond to the current air outlet state, that is, there is no need to adjust the state of the air deflector 7 to enable the air conditioner 100 to meet the air outlet needs of the user.

[0096] In this way, when the control device of the air deflector of the air conditioner according to the embodiment of the present application is used to switch the single-sided air outlet state of the air conditioner 100, the two air deflectors 7 can be controlled to move synchronously to ensure that the two air deflectors 7 can move synchronously towards the left side of the air outlet 9 or synchronously towards the right side of the air outlet 9, so as to avoid the problem of air leakage gaps between the two air deflectors 7. Therefore, it is beneficial to improve the external perception of the air conditioner 100 by the user, ensure that the air outlet effect is relatively stable, and improve the user experience.

[0097] At the same time, it should be noted that the control device of the present invention is used to implement the control method of any of the above embodiments, and when specifically executed, the specific steps executed by the control device may be the same as the steps of the above method, which will not be repeated here.
