Description

Technical Field

[0001] This application relates to the technical field of air conditioners, for example, to a control method, device, and air conditioner for an air conditioner. Background Art

[0002] Currently, with the improvement of people's living standards, the popularity rate of air conditioners is getting higher and higher. However, the air supply methods of conventional air conditioners are mostly relatively single, and can only achieve simple upward air blowing or downward air blowing. When a user is within the air supply range of the air conditioner, the cold or hot air flow blown out from the air outlet of the air conditioner has a relatively high speed, and directly blowing on the user is likely to cause discomfort to the user, and may further affect the user's physical health, resulting in health problems such as colds and rheumatism for groups with relatively poor resistance such as children and the elderly. For this reason, related technologies have proposed an air conditioner indoor unit, including: a housing assembly, in which an air duct is formed inside the housing assembly; an air outlet assembly, including an air outlet window, the air outlet window is detachably connected to the housing assembly, an air outlet is formed inside the air outlet window, and the air outlet is communicated with the air duct; a wind dispersing device, including a curtain, a guiding slide bar, and a driving device, the driving device can drive the curtain to slide and unfold or slide and fold on the guiding slide bar, the curtain can cover the air outlet in a fully unfolded state, and the curtain can be folded at any position on the guiding slide bar in a folded state.

[0003] In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related technologies:

[0004] The related technologies can achieve the effect of no wind feeling directly facing the user position while ensuring the air supply efficiency of the air conditioner. However, during the folding process of the curtain, its stiffness, mass distribution, and geometric shape will all change, and these changes will affect the modal frequency and vibration mode, thereby causing noise generation and affecting the actual use experience of the user.

[0005] It should be noted that the information disclosed in the above background art section is only used to strengthen the understanding of the background of this application, and therefore may include information that does not constitute the prior art known to those of ordinary skill in the art. Summary of the Invention

[0006] To have a basic understanding of some aspects of the disclosed embodiments, a simple summary is given below. The summary is not a general review, nor is it intended to identify key / important constituent elements or delineate the protection scope of these embodiments, but rather serves as a preamble to the subsequent detailed description.

[0007] The embodiments of the present disclosure provide a control method, device, and air conditioner for an air conditioner, which can avoid the occurrence of resonance phenomena, thereby effectively reducing the noise of the air conditioner and being beneficial to improving the user experience.

[0008] In some embodiments, a wind deflector is provided at the air outlet of the air conditioner, and the wind deflector is movable and foldable; the control method includes: obtaining user information in the room; adjusting the working position and folding state of the wind deflector according to the user information in the room so that the air conditioner avoids blowing air at the user; obtaining the modal frequency of the wind deflector; and correcting the folding state of the wind deflector when the modal frequency of the wind deflector meets a preset noise condition to reduce the noise of the air conditioner. In this way, during the operation of the air conditioner, by obtaining the user information in the room, the direct-blow prevention area of the air conditioner can be reasonably determined, and then the working position and folding state of the wind deflector can be adjusted so that the wind deflector is exactly at the air outlet position corresponding to the user. While not affecting the refrigeration and heating effects of the air conditioner, it further realizes avoiding blowing air at the user, improves the no-wind feeling effect of the air conditioner, is beneficial to ensuring the comfortable experience of the user, and reduces the risk of the user getting sick. In addition, after the initial adjustment of the wind deflector, the embodiments of the present disclosure can obtain the modal frequency of the wind deflector in the current state and determine whether it meets the preset noise condition. If it meets, it indicates that the wind deflector may resonate due to air flow excitation. The embodiments of the present disclosure can correct the folding state of the wind deflector to change the modal frequency of the wind deflector, thereby avoiding the occurrence of resonance and effectively reducing the noise of the air conditioner, which is beneficial to improving the user experience.

[0009] In some embodiments, the user information in the room includes the user position and user posture in the room; the adjusting the working position and folding state of the wind deflector according to the user information in the room includes: adjusting the working position of the wind deflector according to the user position in the room so that the wind deflector moves to the position corresponding to the user position; and adjusting the folding state of the wind deflector according to the user posture in the room so that the wind deflector blocks the area corresponding to the user posture. In this way, the embodiments of the present disclosure can first reasonably adjust the working position of the wind deflector based on the user position, and by controlling the wind deflector to accurately move to the position corresponding to the user position, it can avoid blowing air directly at the user, and then realize the no-wind feeling effect, which is beneficial to ensuring the comfortable experience of the user and reducing the risk of the user getting sick. Then the embodiments of the present disclosure can reasonably adjust the folding state of the wind deflector based on the user posture, and by controlling the wind deflector to exactly block the area corresponding to the user posture, it can avoid blowing air at the user and reduce the impact on the refrigeration and heating effects of the air conditioner, which is beneficial to ensuring the working efficiency of the air conditioner.

[0010] In some embodiments, adjusting the folding state of the wind deflector according to the user posture indoors includes: when the user posture indoors is sitting or standing, adjusting the wind deflector to a first folding state; or, when the user posture indoors is lying, adjusting the wind deflector to a second folding state; wherein, the extended length of the first folding state is less than that of the second folding state. In this way, when it is detected that the user's current posture is sitting or standing, the embodiments of the present disclosure can set a relatively compact first folding state, so that the extended length of the wind deflector is just greater than the lateral length corresponding to the user's sitting or standing posture, thereby avoiding the direct blowing of the air outlet on the user, which is beneficial to achieving the no-wind-sensation effect. And when it is detected that the user's current posture is lying, the embodiments of the present disclosure can set a relatively extended second folding state, so that the extended length of the wind deflector is just greater than the lateral length corresponding to the user's lying posture, thereby avoiding the direct blowing of the air outlet on the user, which is beneficial to achieving the no-wind-sensation effect. Moreover, the embodiments of the present disclosure can leave a suitable direct-blowing area at the air outlet of the air conditioner, thereby reducing the impact on the refrigeration and heating effects of the air conditioner and being beneficial to ensuring the working efficiency of the air conditioner.

[0011] In some embodiments, determining that the modal frequency of the wind deflector meets the preset noise condition in the following manner includes: when the absolute value of the difference between the modal frequency of the wind deflector and the operating frequency of the indoor fan is less than or equal to the preset frequency difference, it is determined that the preset noise condition is met. In this way, the embodiments of the present disclosure can further determine the difference between the modal frequency of the wind deflector and the operating frequency of the indoor fan. When the absolute value of this difference is less than or equal to the preset frequency difference, it indicates that the modal frequency of the wind deflector is close to or the same as the operating frequency of the indoor fan in the current folding state, and this state may cause a resonance phenomenon, resulting in the intensification of the vibration of the wind deflector and the increase of the noise of the air conditioner. At this time, the wind deflector needs to make corresponding function adjustments to avoid the occurrence of the resonance phenomenon and reduce the noise of the air conditioner.

[0012] In some embodiments, correcting the folding state of the wind deflector includes: adjusting the extended length of the wind deflector; and / or, adjusting the folding angle of the wind deflector. In this way, when it is determined that the current state of the wind deflector meets the preset noise condition, the embodiments of the present disclosure can timely adjust the extended length and / or the folding angle of the wind deflector, thereby being able to change the stiffness, mass distribution and geometric shape of the wind deflector, and further being able to adjust the modal frequency of the wind deflector so that it no longer meets the preset noise condition. Thus, the occurrence of the resonance phenomenon can be avoided, and the noise of the air conditioner can be effectively reduced, which is beneficial to improving the user experience.

[0013] In some embodiments, adjusting the extended length of the wind deflector includes: periodically increasing the extended length of the wind deflector based on a preset length until the modal frequency of the wind deflector does not meet the preset noise condition. In this way, the embodiments of the present disclosure can gradually increase the extended length of the wind deflector according to the preset length, enabling the modal frequency of the wind deflector to gradually move away from the operating frequency of the indoor fan, thereby reducing the resonance effect, effectively reducing the noise of the air conditioner, and improving the user experience. Moreover, after adjustment, the wind deflector can still avoid blowing air at the user, enhancing the windless feeling effect of the air conditioner, safeguarding the user's comfortable experience, and reducing the user's risk of getting sick.

[0014] In some embodiments, adjusting the folding angle of the wind deflector includes: periodically increasing the folding angle of the wind deflector based on a preset angle until the modal frequency of the wind deflector does not meet the preset noise condition. In this way, the embodiments of the present disclosure can gradually increase the folding angle of the wind deflector according to the preset angle, enabling the modal frequency of the wind deflector to gradually move away from the operating frequency of the indoor fan, thereby reducing the resonance effect, effectively reducing the noise of the air conditioner, and improving the user experience. Moreover, after adjustment, the wind deflector can still avoid blowing air at the user, enhancing the windless feeling effect of the air conditioner, safeguarding the user's comfortable experience, and reducing the user's risk of getting sick.

[0015] In some embodiments, the control device includes: a first acquisition module configured to acquire user information in the room; a first adjustment module configured to adjust the working position and folding state of the wind deflector according to the user information in the room so that the air conditioner avoids blowing air at the user; a second acquisition module configured to acquire the modal frequency of the wind deflector; and a second adjustment module configured to correct the folding state of the wind deflector to reduce the noise of the air conditioner when the modal frequency of the wind deflector meets the preset noise condition.

[0016] In some embodiments, the control device includes: a processor and a memory storing program instructions, and the processor is configured to execute the above-mentioned control method for the air conditioner when running the program instructions.

[0017] In some embodiments, the air conditioner includes: an air conditioner body having an air outlet; a wind deflector disposed at the air outlet, the wind deflector being movable and foldable; and the above-mentioned control device for the air conditioner installed on the air conditioner body.

[0018] The control method, device, and air conditioner for the air conditioner provided by the embodiments of the present disclosure can achieve the following technical effects:

[0019] During the operation of the air conditioner, in the embodiments of the present disclosure, by obtaining user information in the room, the direct-blow prevention area of the air conditioner is reasonably determined, and then the working position and folding state of the wind deflector are adjusted so that the wind deflector is exactly at the air outlet position corresponding to the user. While not affecting the cooling and heating effects of the air conditioner, it further realizes avoiding blowing air at the user, improves the draft-free effect of the air conditioner, is beneficial to ensuring the comfortable experience of the user, and reduces the risk of the user getting sick. In addition, after the initial adjustment of the wind deflector, in the embodiments of the present disclosure, the modal frequency of the wind deflector in the current state can be obtained, and it is judged whether it meets the preset noise condition. If it meets, it indicates that the wind deflector may resonate due to air flow excitation. In the embodiments of the present disclosure, the folding state of the wind deflector can be corrected to change the modal frequency of the wind deflector, thereby avoiding the occurrence of resonance, and further effectively reducing the noise of the air conditioner, which is beneficial to improving the user experience.

[0036] Combined with Figure 1 As shown, the embodiments of the present disclosure provide an air conditioner, including: an air conditioner body 10 and a wind deflector 20. Among them, the air conditioner body 10 has an air outlet 11. The wind deflector 20 is arranged at the air outlet 11. The wind deflector 20 is movable, and moreover, the wind deflector 20 is foldable.

[0037] By using the air conditioner provided in the embodiments of the present disclosure, by adjusting the working position and folding state of the wind deflector 20, the wind deflector 20 is exactly at the air outlet position corresponding to the user. It is possible to avoid blowing air at the user while not affecting the refrigeration and heating effects of the air conditioner, improve the no-wind feeling effect of the air conditioner, be beneficial to ensuring the comfortable experience of the user, and reduce the risk of the user getting sick. At the same time, the occurrence of resonance can be avoided, thereby reducing the noise of the air conditioner and being beneficial to improving the user experience.

[0038] Optionally, in combination with Figure 2 As shown, the wind deflector 20 includes: a plurality of sub-deflectors 21. In this way, the plurality of sub-deflectors 21 are connected in sequence, thereby forming a foldable wind deflector 20.

[0039] Optionally, adjacent sub-deflectors 21 are connected by hinges. In this way, the wind deflector 20 can be folded, which is beneficial to flexibly controlling the wind deflector 20 to better ensure the comfortable experience of the user.

[0040] Optionally, the air conditioner further includes electric push rods 22. There are two electric push rods 22, which are respectively arranged on the left and right sides of the wind deflector 20. In this way, by controlling the electric push rods 22, the wind deflector 20 can be moved, which is beneficial to flexibly controlling the wind deflector 20 to better ensure the comfortable experience of the user.

[0041] Optionally, the air conditioner further includes rotary motors 23. There are two rotary motors 23, which are respectively connected to the two electric push rods 22. In this way, by driving the rotary motors 23 to operate, the electric push rods 22 can be controlled to rotate, and then drive the wind deflector 20 to rotate reasonably. Thus, the wind deflector 20 can be rotated to a plane parallel to the air flow, thereby closing the wind deflector 20 and avoiding adverse effects on the refrigeration and heating effects of the air conditioner, which is beneficial to ensuring the working efficiency of the air conditioner.

[0042] Optionally, the air conditioner further includes a control device 30 / 40 for the air conditioner. The control device 30 / 40 for the air conditioner is installed on the air conditioner body 10 and is electrically connected to the wind deflector 20. In this way, the embodiments of the present disclosure can execute corresponding control methods through the control device 30 / 40, thereby being able to avoid the occurrence of resonance and reduce the noise of the air conditioner.

[0043] Based on the above air conditioner, in combination with Figure 3 As shown, the embodiments of the present disclosure provide a control method for an air conditioner, including:

[0044] S101, the control device obtains user information in the room.

[0045] S102, the control device adjusts the working position and folding state of the wind deflector according to the user information in the room so that the air conditioner avoids blowing air at the user.

[0046] S103, the control device obtains the modal frequency of the wind deflector.

[0047] S104, when the modal frequency of the wind deflector meets the preset noise condition, the control device corrects the folding state of the wind deflector to reduce the noise of the air conditioner.

[0048] By using the control method for an air conditioner provided in the embodiments of the present disclosure, during the operation of the air conditioner, the anti-direct-blowing area of the air conditioner can be reasonably determined by obtaining the user information in the room, and then the working position and folding state of the wind deflector can be adjusted so that the wind deflector is exactly at the air outlet position corresponding to the user. While not affecting the cooling and heating effects of the air conditioner, it further realizes avoiding blowing directly at the user, improves the no-wind feeling effect of the air conditioner, is beneficial to ensuring the comfortable experience of the user, and reduces the risk of the user getting sick. In addition, after the initial adjustment of the wind deflector, the embodiments of the present disclosure can obtain the modal frequency of the wind deflector in the current state and determine whether it meets the preset noise condition. If it meets, it indicates that the wind deflector may resonate due to air flow excitation. The embodiments of the present disclosure can change the modal frequency of the wind deflector by correcting the folding state of the wind deflector, thereby avoiding the occurrence of resonance, and further effectively reducing the noise of the air conditioner, which is beneficial to improving the user experience.

[0049] Optionally, the control device obtains the user information in the room, including: the control device controls the camera device to collect the user image in the room; the control device analyzes the user image in the room to determine the user information in the room.

[0050] In this way, the embodiments of the present disclosure can capture the user image in the room by installing a high-definition camera and extract the user information therefrom, so as to be able to reasonably adjust the working state of the wind deflector so that it is exactly at the air outlet position corresponding to the user. It is beneficial to realize avoiding blowing directly at the user to improve the no-wind feeling effect of the air conditioner.

[0051] Optionally, the user information in the room includes the user position and user posture in the room. In this way, by obtaining the user position and user posture in the room, the embodiments of the present disclosure can quickly determine the anti-direct-blowing area of the air conditioner outlet, so as to control the wind deflector to be exactly at the air outlet position corresponding to the user.

[0052] Optionally, the embodiments of the present disclosure may also include more user information, not limited to the above several types of user information. The working position and folding state of the wind deflector can also be reasonably set corresponding to other user information, which will not be listed one by one here. Thus, based on the above various user information in the room, the embodiments of the present disclosure can reasonably control the wind deflector to be exactly at the air outlet position corresponding to the user.

[0053] Optionally, the control device adjusts the working position and folding state of the wind deflector according to the user information in the room, including: the control device adjusts the working position of the wind deflector according to the user position in the room so that the wind deflector moves to the position corresponding to the user position; the control device adjusts the folding state of the wind deflector according to the user posture in the room so that the wind deflector blocks the area corresponding to the user posture.

[0054] In this way, the embodiment of the present disclosure can first reasonably adjust the working position of the wind deflector based on the user position. By controlling the wind deflector to accurately move to the position corresponding to the user position, the direct blowing of the air outlet on the user can be avoided, and thus the effect of no wind feeling can be achieved, which is beneficial to ensuring the comfortable experience of the user and reducing the risk of the user getting sick. Then, the embodiment of the present disclosure can reasonably adjust the folding state of the wind deflector based on the user posture. By controlling the wind deflector to exactly block the area corresponding to the user posture, the air outlet avoiding the user can be achieved, and the influence on the refrigeration and heating effects of the air conditioner can be reduced, which is beneficial to ensuring the working efficiency of the air conditioner.

[0055] Optionally, the control device adjusts the folding state of the wind deflector according to the user posture in the room, including: when the user posture in the room is sitting or standing, the control device adjusts the wind deflector to the first folding state; or when the user posture in the room is lying, the control device adjusts the wind deflector to the second folding state. Wherein, the extension length of the first folding state is less than the extension length of the second folding state.

[0056] In this way, when it is detected that the current user posture is sitting or standing, the embodiment of the present disclosure can set the relatively compact first folding state, so that the extension length of the wind deflector is just greater than the horizontal length corresponding to the sitting or standing posture of the user, thereby avoiding the direct blowing of the air outlet on the user, which is beneficial to achieving the effect of no wind feeling. When it is detected that the current user posture is lying, the embodiment of the present disclosure can set the relatively stretched second folding state, so that the extension length of the wind deflector is just greater than the horizontal length corresponding to the lying posture of the user, thereby avoiding the direct blowing of the air outlet on the user, which is beneficial to achieving the effect of no wind feeling. And, the embodiment of the present disclosure can keep a suitable direct blowing area at the air outlet of the air conditioner, thereby reducing the influence on the refrigeration and heating effects of the air conditioner, which is beneficial to ensuring the working efficiency of the air conditioner.

[0057] Based on the above air conditioner, combined with Figure 4 as shown, the embodiment of the present disclosure provides another control method for an air conditioner, including:

[0058] S201, the control device obtains the user information in the room.

[0059] S202, the control device adjusts the working position and folding state of the wind deflector according to the user information in the room so that the air conditioner avoids blowing air on the user.

[0060] S203, the control device obtains the modal frequency of the wind deflector.

[0061] S204, when the absolute value of the difference between the modal frequency of the wind deflector and the operating frequency of the indoor fan is less than or equal to a preset frequency difference, the control device determines that the preset noise condition is satisfied.

[0062] S205, the control device corrects the folding state of the wind deflector to reduce the noise of the air conditioner.

[0063] By using the control method for an air conditioner provided in the embodiments of the present disclosure, it is possible to determine whether the preset noise condition is satisfied by obtaining the modal frequency of the wind deflector in the current state. Specifically, the difference between the modal frequency of the wind deflector and the operating frequency of the indoor fan can be determined. When the absolute value of this difference is less than or equal to the preset frequency difference, it indicates that the modal frequency of the wind deflector in the current folding state is close to or the same as the operating frequency of the indoor fan. In this state, resonance may occur, resulting in increased vibration of the wind deflector and increased noise of the air conditioner. At this time, the embodiments of the present disclosure can reasonably correct the current folding state of the wind deflector, thereby being able to adaptively change the stiffness, mass distribution, and geometric shape of the wind deflector, and further being able to adjust the modal frequency of the wind deflector to avoid the occurrence of resonance, and thus effectively reduce the noise of the air conditioner, which is beneficial to improving the user experience.

[0064] Optionally, the control device obtains the modal frequency of the wind deflector, including: the control device matches according to the folding state of the wind deflector in the associated information library to determine the modal frequency corresponding to the folding state of the wind deflector.

[0065] In this way, the embodiments of the present disclosure can determine the modal frequencies at different folding angles through experimental modal analysis. Then, the data obtained from experiments and simulations are organized into a table or database format, including information such as folding angle, corresponding modal frequency, modal vibration mode, etc. Finally, a corresponding database structure can be designed to store in advance the correspondence between the folding angle and the modal frequency. Thus, during the use of the air conditioner, the correspondence between the folding angle and the modal frequency can be quickly queried to accurately determine whether the preset noise condition is satisfied, thereby being beneficial to avoiding the occurrence of resonance and reducing the noise of the air conditioner.

[0066] Optionally, the preset frequency difference can be set in combination with the vibration mode of the wind deflector. Preferably, the preset frequency difference can be set to 3 Hz to determine whether the modal frequency of the wind deflector in the current folding state is close to or the same as the operating frequency of the indoor fan. The preset frequency difference can also be adjusted according to the actual needs of the user and can be set to other arbitrary reasonable values such as 2 Hz or 4 Hz.

[0067] Optionally, the control device corrects the folding state of the wind deflector, including: the control device adjusts the extension length of the wind deflector; and / or, the control device adjusts the folding angle of the wind deflector. In this way, when it is determined that the current state of the wind deflector meets the preset noise condition, the embodiments of the present disclosure can timely adjust the extension length and / or folding angle of the wind deflector, so as to change the stiffness, mass distribution, and geometric shape of the wind deflector, and further adjust the modal frequency of the wind deflector so that it no longer meets the preset noise condition. Thereby, the occurrence of resonance can be avoided, and the noise of the air conditioner can be effectively reduced, which is beneficial to improving the user experience.

[0068] Optionally, the control device adjusts the extension length of the wind deflector, including: the control device periodically increases the extension length of the wind deflector based on a preset length until the modal frequency of the wind deflector does not meet the preset noise condition.

[0069] In this way, the embodiments of the present disclosure can gradually increase the extension length of the wind deflector according to the preset length, which can make the modal frequency of the wind deflector gradually move away from the operating frequency of the indoor fan, thereby reducing the resonance effect, effectively reducing the noise of the air conditioner, and being beneficial to improving the user experience. Moreover, after the wind deflector is adjusted, it can still avoid blowing air at the user, improving the windless feeling effect of the air conditioner, being beneficial to ensuring the user's comfortable experience, and reducing the risk of the user getting sick.

[0070] Optionally, the preset length is 1 cm, so as to control the gradual increase of the extension length of the wind deflector. The preset length can also be adjusted according to the actual needs of the user, and can also be set to other reasonable values such as 2 cm or 3 cm.

[0071] Optionally, the control device adjusts the folding angle of the wind deflector, including: the control device periodically increases the folding angle of the wind deflector based on a preset angle until the modal frequency of the wind deflector does not meet the preset noise condition.

[0072] In this way, the embodiments of the present disclosure can gradually increase the folding angle of the wind deflector according to the preset angle, which can make the modal frequency of the wind deflector gradually move away from the operating frequency of the indoor fan, thereby reducing the resonance effect, effectively reducing the noise of the air conditioner, and being beneficial to improving the user experience. Moreover, after the wind deflector is adjusted, it can still avoid blowing air at the user, improving the windless feeling effect of the air conditioner, being beneficial to ensuring the user's comfortable experience, and reducing the risk of the user getting sick.

[0073] Optionally, the preset angle is 1°, so as to control the gradual increase of the folding angle of the wind deflector. The preset angle can also be adjusted according to the actual needs of the user, and can also be set to other reasonable values such as 2° or 3°.

[0074] Combined with Figure 5As shown in the figure, an embodiment of the present disclosure provides a control device 30 for an air conditioner, including a first acquisition module 31, a first adjustment module 32, a second acquisition module 33, and a second adjustment module 34. Among them, the first acquisition module 31 is configured to acquire user information in the room. The first adjustment module 32 is configured to adjust the working position and folding state of the wind deflector according to the user information in the room, so that the air conditioner avoids blowing air at the user. The second acquisition module 33 is configured to acquire the modal frequency of the wind deflector. The second adjustment module 34 is configured to correct the folding state of the wind deflector when the modal frequency of the wind deflector meets a preset noise condition, so as to reduce the noise of the air conditioner.

[0075] By using the control device 30 for the air conditioning system provided by the embodiment of the present disclosure, during the operation of the air conditioner, the direct-blow prevention area of the air conditioner can be reasonably determined by acquiring the user information in the room, and then the working position and folding state of the wind deflector can be adjusted, so that the wind deflector is exactly at the air outlet position corresponding to the user. While not affecting the cooling and heating effects of the air conditioner, it further realizes avoiding blowing air at the user, improves the no-wind feeling effect of the air conditioner, is beneficial to ensuring the user's comfortable experience, and reduces the risk of the user getting sick. In addition, after the initial adjustment of the wind deflector, the embodiment of the present disclosure can acquire the modal frequency of the wind deflector in the current state and judge whether it meets the preset noise condition.
