Description

Technical Field

[0001] The present invention relates to air conditioning technology, in particular to an air conditioner and a noise control method thereof. Background Art

[0002] Noise is defined as a factor that affects indoor comfort. Whether at work, school, or in daily life, we are all troubled by noise. Air conditioners with different fans and wind speeds produce different noise levels. Even air conditioners of the same specifications and models can produce varying noise levels depending on the production environment and operating conditions.

[0003] White noise, a natural phenomenon, is characterized by uniform energy across different frequency bands. Within the audible frequency range, this uniform energy can help calm people, help them focus, and reduce noise levels, thus calming their mood. To this end, white noise modules are often incorporated into air conditioners to mask any unwanted noise when ambient noise levels are high.

[0004] However, white noise only works under certain conditions. If the ambient noise level is excessive, adding white noise is meaningless. Furthermore, different people have different noise sensitivities; some may find the same noise unacceptable, while others may not. Therefore, the existing approach of simply emitting white noise is not truly and effectively addressing the user experience issues caused by noise. Summary of the Invention

[0005] An object of the first aspect of the present invention is to overcome at least one drawback of the prior art and provide a noise control method for an air conditioner to truly and effectively perform noise self-diagnosis and noise control.

[0006] A further object of the first aspect of the present invention is to simplify the control logic of the noise control method and improve its response speed.

[0007] Another further object of the first aspect of the present invention is to effectively reduce noise and improve user comfort experience.

[0008] The second aspect of the present invention aims to provide an air conditioner that can truly and effectively perform noise self-diagnosis and noise control.

[0009] According to a first aspect of the present invention, the present invention provides a noise control method for an air conditioner, comprising:

[0010] When a preset noise detection condition is met, starting the noise detection module of the air conditioner to detect the ambient noise value of the environment in which the air conditioner is located;

[0011] When the environmental noise value is higher than the current environmental standard noise value, obtaining a reaction state of a user in the environment where the air conditioner is located; and

[0012] The air conditioner is selectively regulated according to the reaction state and the ambient noise value to selectively alleviate the ambient noise in the environment where the air conditioner is located.

[0013] Optionally, the step of selectively regulating the air conditioner according to the reaction state and the ambient noise value includes:

[0014] determining whether the user has an uncomfortable reaction according to the reaction state;

[0015] If so, regulating the air conditioner according to the environmental noise value to alleviate the environmental noise in the environment where the air conditioner is located;

[0016] If not, the air conditioner is controlled to operate normally.

[0017] Optionally, the noise control method further includes:

[0018] If it is determined according to the reaction state that the user has no discomfort reaction, the environmental standard noise value is updated to the acquired environmental noise value.

[0019] Optionally, the step of regulating the air conditioner according to the ambient noise value includes:

[0020] Determining whether the ambient noise value is within a noise range that can be covered by white noise;

[0021] If so, controlling the white noise generating module of the air conditioner to emit white noise;

[0022] If not, the operating frequency of the compressor of the air conditioner and / or the speed of the indoor fan of the air conditioner are reduced.

[0023] Optionally, the operating frequency of the compressor of the air conditioner is reduced by:

[0024] reducing the operating frequency of the compressor by a preset amount, or lowering the operating frequency of the compressor by one gear; and / or

[0025] The method of reducing the indoor fan speed of the air conditioner is as follows:

[0026] The speed of the indoor fan is reduced by a preset amount, or the speed of the indoor fan is reduced by one gear.

[0027] Optionally, the step of determining whether the ambient noise value is within a noise range that can be covered by white noise includes:

[0028] Determining whether the ambient noise value is lower than a first preset noise value;

[0029] If yes, it is determined that the ambient noise value is within the noise range that can be covered by white noise;

[0030] If not, it is determined that the environmental noise value is not within the noise range covered by white noise;

[0031] The first preset noise value is greater than the environmental standard noise value.

[0032] Optionally, when the ambient noise value is not within the noise range covered by white noise, the noise control method further includes:

[0033] The ambient noise value corresponding to the air conditioner in the current operating mode is recorded and fed back to the after-sales platform.

[0034] Optionally, the preset noise detection condition includes any one of the following:

[0035] The air conditioner starts running after receiving the start instruction;

[0036] The operating frequency of the compressor and / or the speed of the indoor fan of the air conditioner changes.

[0037] Optionally, the step of obtaining a user's reaction state in the environment where the air conditioner is located includes:

[0038] Acquiring image information of a user in the environment where the air conditioner is located; and

[0039] Determine the user's reaction state based on the image information;

[0040] The image information includes:

[0041] Image information of users in the environment where the air conditioner is located, collected after the air conditioner is turned on; and / or image information of users in the environment where the air conditioner is located, collected by an image acquisition device interconnected with the air conditioner after the air conditioner is turned on.

[0042] According to a second aspect of the present invention, the present invention further provides an air conditioner, comprising:

[0043] a noise detection module, configured to detect an ambient noise level in an environment where the air conditioner is located; and

[0044] The control device includes a processor and a memory, wherein a machine executable program is stored in the memory, and when the machine executable program is executed by the processor, it is used to implement the noise control method described in any of the above solutions.

[0045] When the ambient noise level exceeds the current standard noise level, the noise control method of the present invention does not directly regulate the air conditioner to reduce noise. Instead, it first obtains the user's reaction to the air conditioner's environment. Based on the user's reaction and the obtained ambient noise level, it comprehensively determines whether the air conditioner needs to be regulated to alleviate the ambient noise. This is because different users have different tolerances for noise and different users cannot tolerate different types of noise. By selectively regulating the air conditioner based on the user's actual noise reaction and the ambient noise level, the present invention can more effectively diagnose whether the ambient noise exceeds the user's tolerance level and whether adjustments are truly necessary, thereby avoiding unnecessary adjustments that impose additional operating burdens on the air conditioner and increase its energy consumption.

[0046] The noise control method of the present invention starts detecting ambient noise only when preset noise detection conditions are met, rather than real-time or periodic detection, which reduces the detection burden of the noise detection module and its energy consumption, and improves the accuracy of the air conditioner noise detection timing.

[0047] Furthermore, if the user does not experience any discomfort when the ambient noise level exceeds the standard ambient noise level, this indicates that the decibel ambient noise level is within the user's tolerable range, and no adjustments to the air conditioner are required. Therefore, the present invention updates the previously obtained standard ambient noise level to the newly acquired ambient noise level. If the next acquired ambient noise level remains unchanged, steps such as obtaining and analyzing the user's reaction status can be omitted. This simplifies the air conditioner's control logic and improves its response speed, while ensuring that the user does not experience any discomfort.

[0048] Furthermore, when the user feels uncomfortable and needs to adjust the air conditioner, the present invention further adopts different control measures based on whether the obtained ambient noise value is within the noise range that can be covered by white noise. That is, when the ambient noise value is within the noise range that can be covered by white noise, white noise can be emitted through the white noise module to cover or shield the ambient noise; when the ambient noise value exceeds the noise range that can be covered by white noise, the compressor operating frequency and / or the indoor fan speed are reduced to reduce the ambient noise from the source. In this way, not only can white noise be effectively used to solve the discomfort problem caused by ambient noise to the user, but also, the misunderstanding of white noise shielding noise by those skilled in the art is reasonably avoided. When white noise cannot shield the ambient noise, the ambient noise is reduced by other means to avoid causing discomfort to the user, thus completely solving the use troubles caused by ambient noise to the user.

[0055] Figure 5 FIG. 1 is a schematic structural block diagram of an air conditioner according to an embodiment of the present invention. DETAILED DESCRIPTION

[0056] The present invention first provides a noise control method for an air conditioner, the noise control method comprising:

[0057] When the preset noise detection condition is met, the noise detection module of the air conditioner is started to detect the ambient noise value in the environment where the air conditioner is located;

[0058] When the environmental noise value is higher than the current environmental standard noise value, obtaining the reaction state of the user in the environment where the air conditioner is located; and

[0059] The air conditioner is selectively regulated according to the reaction state and the ambient noise value to selectively alleviate the ambient noise in the environment where the air conditioner is located.

[0060] Specifically, Figure 1 FIG1 is a schematic flow chart of a noise control method for an air conditioner according to an embodiment of the present invention. The noise control method for an air conditioner according to the present invention specifically includes:

[0061] Step S10, determining whether a preset noise detection condition is met; if so, proceeding to step S20;

[0062] Step S20, starting the noise detection module of the air conditioner to detect the ambient noise value in the environment where the air conditioner is located;

[0063] Step S30: Determine whether the ambient noise value is higher than the current ambient noise standard value; if so, go to step S40; if not, return to step S10;

[0064] Step S40, obtaining the reaction state of the user in the environment where the air conditioner is located; and

[0065] Step S50 , selectively regulating the air conditioner according to the user's reaction state and the ambient noise value to selectively alleviate the ambient noise in the environment where the air conditioner is located.

[0066] When the ambient noise level exceeds the current standard noise level, the noise control method of the present invention does not directly adjust the air conditioner to reduce noise. Instead, it first obtains the user's reaction to the air conditioner's environment. Based on the user's reaction and the obtained ambient noise level, it comprehensively determines whether the air conditioner needs to be adjusted to alleviate the ambient noise. This is because different users have different noise tolerances and different users cannot tolerate different types of noise. The present invention selectively adjusts the air conditioner based on the user's actual noise reaction and the ambient noise level, which can more effectively diagnose whether the ambient noise exceeds the user's tolerance level and whether adjustment is truly necessary, thereby avoiding unnecessary adjustments that impose additional operating burdens on the air conditioner and increase its energy consumption.

[0067] The noise control method of the present invention starts detecting ambient noise only when preset noise detection conditions are met, rather than real-time or periodic detection, which reduces the detection burden of the noise detection module and its energy consumption, and improves the accuracy of the air conditioner noise detection timing.

[0068] In some embodiments, the preset noise detection condition includes any one of the following:

[0069] The air conditioner starts running after receiving the start command;

[0070] The air conditioner's compressor operating frequency and / or indoor fan speed have changed.

[0071] In other words, the noise detection module only detects ambient noise when the air conditioner is running, or when the compressor frequency and / or indoor fan speed change. This is because ambient noise changes only occur when the air conditioner is running, or when the compressor frequency and / or indoor fan speed change. Under other normal operating conditions, the noise generated by the air conditioner rarely changes noticeably. Therefore, not operating the noise detection module during other passenger conditions reduces its detection burden and energy consumption.

[0072] Specifically, the compressor operating frequency and / or indoor fan speed of an air conditioner typically change after the air conditioner's operating mode is adjusted. Therefore, it is possible to determine whether the compressor operating frequency and / or indoor fan speed have changed by monitoring whether the air conditioner's operating mode has changed. Of course, it is also possible to directly obtain the compressor operating frequency and indoor fan speed and determine whether the compressor operating frequency and / or indoor fan speed have changed by comparing them.

[0073] Figure 2 is a schematic flow chart of selectively regulating an air conditioner according to a user's reaction state and an ambient noise level according to an embodiment of the present invention. Figure 2 The steps of selectively regulating the air conditioner according to the user's reaction state and the ambient noise value may specifically include:

[0074] Step S51, judging whether the user has an uncomfortable reaction according to the reaction state; if so, go to step S52, if not, go to step S53;

[0075] Step S52, regulating the air conditioner according to the ambient noise value to alleviate the ambient noise in the environment where the air conditioner is located; and

[0076] Step S53: Control the air conditioner to operate normally.

[0077] In other words, only if the user experiences discomfort does the current ambient noise level exceed their tolerance, and appropriate adjustments must be made to the air conditioner to reduce and mitigate the ambient noise, thereby ensuring user comfort. If the user does not experience discomfort, there is no need to adjust the air conditioner even if the ambient noise level exceeds the current standard. This simplifies the air conditioner's control logic, reduces energy consumption, and minimizes any adverse effects on the air conditioner's cooling or heating performance.

[0078] In some embodiments, the noise control method of the present invention further comprises:

[0079] If it is determined based on the reaction state that the user has no discomfort reaction, the environmental standard noise value is updated to the acquired environmental noise value.

[0080] If the user does not experience any discomfort when the ambient noise level exceeds the standard ambient noise level, this indicates that the decibel ambient noise level is within the user's tolerable range, and no adjustments to the air conditioner are required. Therefore, the present invention updates the previously obtained standard ambient noise level to the newly acquired ambient noise level. If the next acquired ambient noise level remains unchanged, steps such as obtaining and analyzing the user's reaction status can be omitted. This simplifies the air conditioner's control logic and improves its response speed, while ensuring that the user does not experience any discomfort.

[0081] Specifically, Figure 3 is a schematic flow chart of selectively regulating an air conditioner according to another embodiment of the present invention based on a user's reaction state and an ambient noise level. Figure 3 The steps of selectively regulating the air conditioner according to the user's reaction state and the ambient noise value may specifically include:

[0082] Step S51, judging whether the user has an uncomfortable reaction according to the reaction state; if so, go to step S52, if not, go to step S53;

[0083] Step S52, regulating the air conditioner according to the ambient noise value to alleviate the ambient noise in the environment where the air conditioner is located; and

[0084] Step S53, controlling the air conditioner to operate normally;

[0085] Step S54: Update the environmental standard noise value to the acquired environmental noise value.

[0086] It is understandable that there is no restriction on the order of the above steps S53 and S54.

[0087] The inventors recognized that white noise can only effectively attenuate or shield noise at levels lower than those of white noise. If the ambient noise level is excessive, adding white noise is meaningless. Furthermore, the compressor and indoor fan are the primary noise sources for air conditioners. Therefore, adjusting the compressor frequency and indoor fan speed can alter the noise level generated by the air conditioner.

[0088] To this end, in some embodiments, see Figure 4 The schematic flow chart of selectively regulating an air conditioner according to another embodiment of the present invention according to the user's reaction state and the ambient noise level is shown, wherein step S52 of regulating the air conditioner according to the ambient noise level may specifically include:

[0089] Step S521, determine whether the ambient noise value is within the noise range that can be covered by white noise; if so, go to step S522, if not, go to step S523;

[0090] Step S522, controlling the white noise generating module of the air conditioner to emit white noise;

[0091] Step S523: reducing the operating frequency of the compressor of the air conditioner and / or the speed of the indoor fan of the air conditioner.

[0092] When the user feels uncomfortable and needs to adjust the air conditioner, the present invention further takes different control measures according to whether the acquired ambient noise value is within the noise range covered by white noise. That is, when the ambient noise value is within the noise range covered by white noise, white noise can be emitted through the white noise module to cover or shield the ambient noise; when the ambient noise value exceeds the noise range covered by white noise, the compressor operating frequency and / or the indoor fan speed are reduced to reduce the ambient noise from the source.

[0093] In this way, not only can white noise be effectively used to solve the discomfort problem caused by ambient noise to users, but it also reasonably avoids the misunderstanding of technical personnel in this field that white noise shields noise. When white noise cannot shield ambient noise, ambient noise can be reduced by other means to avoid causing discomfort to users, thus completely solving the usage problems caused by ambient noise to users.

[0094] It should be noted that the reduction in the operating frequency of the compressor and / or the speed of the indoor fan may have a certain impact on the cooling efficiency or heating efficiency of the air conditioner. However, if the reduction is properly controlled, the impact will not be large and cannot be intuitively felt by the user. Therefore, a suitable balance can be found between heating / cooling efficiency and environmental noise, which neither affects the user's cooling / heating experience nor solves the problem of discomfort caused by excessive noise to the user.

[0095] To address the long-term impact of reducing the compressor operating frequency and / or indoor fan speed of the air conditioner on the cooling / heating performance of the air conditioner, in some embodiments, when the ambient noise value is not within the noise range covered by white noise, the noise control method of the present invention further includes:

[0096] Record the ambient noise value corresponding to the air conditioner's current operating mode and feed it back to the after-sales platform.

[0097] In other words, simply relying on white noise alone cannot solve the environmental noise problem. The noise parameters of the air conditioner in the current operating mode are clearly too high, and are considered unqualified scene data. This invention records this information and promptly provides feedback to the after-sales platform, which helps after-sales personnel to promptly learn and resolve the problem, and also facilitates the continuous upgrading and improvement of the product.

[0098] In some embodiments, the operating frequency of the air conditioner compressor is reduced by:

[0099] Reduce the compressor operating frequency by a preset amount, or lower the compressor operating frequency by one gear.

[0100] That is, the operating frequency of the compressor is slowly reduced until the ambient noise meets the requirements or can be covered or shielded by white noise. At this time, the change in the operating frequency of the compressor has the least impact on the cooling efficiency or heating efficiency.

[0101] In some embodiments, the method of reducing the speed of the indoor fan of the air conditioner is:

[0102] Reduce the indoor fan speed by a preset amount, or lower the indoor fan speed by one gear.

[0103] That is, the speed of the indoor fan is slowly reduced until the ambient noise meets the requirements or can be covered or shielded by white noise. At this time, the change in the speed of the indoor fan has the least impact on the cooling efficiency or heating efficiency, or the user's wind experience.

[0104] In some embodiments, the step of determining whether the ambient noise value is within the noise range covered by white noise may specifically include:

[0105] Determining whether the ambient noise value is lower than a first preset noise value;

[0106] If so, it is determined that the ambient noise value is within the noise range that can be covered by white noise;

[0107] If not, it is determined that the ambient noise value is not within the noise range covered by white noise;

[0108] The first preset noise value is greater than the environmental standard noise value.

[0109] Furthermore, the magnitude of the white noise generated by the white noise generating module can be determined according to the obtained ambient noise value. Preferably, the white noise has the best effect of shielding the ambient noise when the emitted white noise is 15 decibels higher than the ambient noise value.

[0110] In some embodiments, step S40 of obtaining the user's reaction state in the environment where the air conditioner is located may specifically include:

[0111] Acquiring image information of a user in an environment where the air conditioner is located; and

[0112] The user's reaction state is determined based on the image information.

[0113] There are many ways to obtain user image information, and image information acquisition is simple and convenient, so it is easier to implement and has lower costs.

[0114] Furthermore, the user's image information can more intuitively and clearly display the user's reaction state without the need for complex data analysis and processing. Therefore, determining the user's reaction state based on the user's image information is faster and more accurate.

[0115] Furthermore, the user's image information may specifically include:

[0116] Image information of users in the environment of the air conditioner collected after the air conditioner is turned on; and / or image information of users in the environment of the air conditioner collected by an image acquisition device interconnected with the air conditioner after the air conditioner is turned on.

[0117] In other words, the user's image information can be obtained through the air conditioner's own image acquisition module, or through other image acquisition devices interconnected with the air conditioner. The acquisition of image information is more flexible and convenient, and can cover every corner of the air conditioner's environment as much as possible, with a more comprehensive perspective.

[0118] The present invention also provides an air conditioner, Figure 5 FIG. 1 is a schematic structural block diagram of an air conditioner according to an embodiment of the present invention. The air conditioner 1 of the present invention comprises a noise detection module 10 and a control device 20 .

[0119] The noise detection module 10 is used to detect the ambient noise value in the environment where the air conditioner is located.

[0120] The control device 20 includes a processor 21 and a memory 22 . The memory 22 stores a machine executable program 23 . When the machine executable program 23 is executed by the processor 21 , it is used to implement the noise control method described in any of the above embodiments.

[0121] Specifically, the processor 21 can be a central processing unit (CPU), or a digital processing unit, etc. The processor 21 sends and receives data through a communication interface. The memory 22 is used to store the program executed by the processor 21. The memory 22 is any medium that can be used to carry or store the desired program code in the form of instructions or data structures and can be accessed by a computer, and can also be a combination of multiple memories. The above-mentioned machine executable program 23 can be downloaded from a computer-readable storage medium to a corresponding computing / processing device or downloaded to a computer or external storage device via a network (such as the Internet, a local area network, a wide area network and / or a wireless network).

For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0123] Furthermore, it should be noted that in the description of the present invention, each functional module can be a physical module composed of multiple structures, components or electronic components, or a virtual module composed of multiple programs; each functional module can be a module that exists independently of each other, or a module divided according to function from an integral module.
