[0030] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] First, it should be noted that in the embodiments of the present application, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "includes a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0032] Secondly, it should be noted that in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0033] In the related art, an active noise control system for reducing the noise of an air conditioner fan includes: a sensor, which is used to monitor the characteristics of the noise generated by the air conditioner and output a corresponding noise monitoring signal; a control module, which is connected to the sensor and executes an active noise control method, performs noise signal analysis and noise reduction signal calculation based on the noise monitoring signal and generates a control signal; a speaker array, which is connected to the control module and generates an active control sound based on the control signal for canceling the noise generated by the air conditioner, thereby realizing active noise control.

[0034] However, when using the above control system, there is a situation where the active control sound and the noise emitted by the air conditioner do not cancel each other out, and the noise elimination effect is not good.

[0035] The reasons why the active control sound of the above control system and the noise from the air conditioner do not cancel each other out are:

[0036] The active noise control system of air conditioners is similar to the active noise reduction scheme of noise-cancelling headphones, both of which actively reduce existing noise. However, there are obvious differences in the use environment of air conditioners and noise-cancelling headphones: noise-cancelling headphones are close to the human ear when used, which is a closed environment; while air conditioners are used at a certain distance from the user, and this distance changes at any time as the person moves around, that is, the use of air conditioners is in an open environment.

[0037] For the active noise reduction of the air conditioner, when the user's standing position relative to the air conditioner is different, the sound received by the human ear after the active control sound and the noise emitted by the air conditioner are offset will be different. That is, when the active control sound is constant, when the user is in a standing position relative to the air conditioner, the human ear will receive the sound after the active control sound and the noise are completely offset, and the control system achieves a good active noise reduction effect; when the user is in another standing position relative to the air conditioner, the human ear will receive the sound after the active control sound and the noise are not completely offset, and the active noise reduction does not have a good noise reduction effect, and noise still exists at this time.

[0038] In response to the above problems, after analyzing the sources of noise generated by the air conditioner, it was found that during the operation of the air conditioner, the whistle sound caused by the speed parameters of the air supply system of the air conditioner indoor unit, the refrigerant flow sound caused by the opening parameters of the electronic expansion valve, and the compressor vibration transmission sound caused by the compressor operating frequency will all generate noise.

[0039] In the process of active noise reduction, the active control sound emitted by the active control system will be used to offset any of the above noises or a combination of several noises. Since the generation of noise is related to the operating parameters of various components in the air conditioner, when the active control sound and the noise do not offset each other, the object generating the noise can be further controlled, that is, the relevant parameters of the object generating the noise can be adjusted, so as to reduce the noise.

[0040] In view of this, the present application provides a control method, device and equipment for an air conditioner, wherein the air conditioner includes an air conditioner body and a noise reduction module. First, a first sound spectrum and an object of the first sound spectrum are obtained when the air conditioner body is in operation; second, when the first sound spectrum is greater than a preset spectrum, that is, the first sound spectrum is a noise spectrum, the noise reduction module is turned on at this time to emit an anti-noise sound; finally, a second sound spectrum is obtained when the air conditioner body is in operation, and when the second sound spectrum is greater than a preset spectrum, that is, the anti-noise sound fails to effectively offset the noise, the operating parameters of the object of the first sound spectrum are lowered. By determining the correspondence between the noise and the object emitting the noise, when the anti-noise sound fails to effectively offset the noise, the operating parameters of the object emitting the noise can be further adjusted, thereby achieving a good noise elimination effect to improve the user experience.

[0041] Figure 1 This is a schematic diagram of the connection between the air conditioner body and the noise reduction module provided in the embodiment of the present application; Figure 1 The air conditioner of the embodiment of the present application includes an air conditioner body 10 and a noise reduction module 20. Exemplarily, the air conditioner body 10 includes a cross-flow fan 110 and a vortex tongue assembly 120, the vortex tongue assembly 120 includes a front vortex tongue 121 and a rear vortex tongue 122, the front vortex tongue 121 and the rear vortex tongue 122 define an opening connected to the air outlet of the air conditioner body 10; the cross-flow fan 110 is installed between the front vortex tongue 121 and the rear vortex tongue 122; the noise reduction module 20 is installed on the rear vortex tongue 122 and close to the air outlet. Among them, the arrow line indicates the flow direction of the wind.

[0042] Figure 2 A flow chart of a method for controlling an air conditioner provided in an embodiment of the present application is shown in FIG. Figure 2 , the method comprising:

[0043] S101. Acquire a first sound spectrum when an air conditioner is in operation, and an object of the first sound spectrum, wherein the object of the first sound spectrum includes at least one of an air supply system, an electronic expansion valve, and a compressor of the air conditioner.

[0044] Specifically, the first sound spectrum when the air conditioner is running corresponds to the information of the first sound emitted by the air conditioner during operation after the air conditioner is started. The object emitting the first sound includes at least one of the air supply system, the electronic expansion valve and the compressor of the air conditioner, wherein the air supply system includes a cross-flow fan.

[0045] For example, the first sound during operation of the air conditioner can be obtained by a sound sensor, and the sound sensor is arranged on the rear vortex tongue. It can be understood that the sound sensor is close to the noise source and is close to the inside of the air conditioner body; the noise reduction module is close to the air outlet. In this way, the sound sensor can easily capture the first sound during operation of the air conditioner body.

[0046] Furthermore, the information of the first sound when the air conditioner is running, that is, the first sound spectrum, can be obtained through the audio analysis software. Specifically, the first sound acquired by the sound sensor is imported into the audio analysis software, and the audio analysis software can convert the first sound data into a spectrum diagram. The spectrum diagram shows the energy distribution information of the first sound at different frequencies, that is, the first sound spectrum.

[0047] By observing the first sound spectrum and analyzing the energy distribution at different frequencies, the object of the first sound spectrum can be identified. It can be understood that, depending on the energy distribution, the object of the first sound spectrum may be any one of the air supply system, the electronic expansion valve and the compressor, or a combination thereof.

[0048] In some possible implementations, a first sound during operation of the air conditioner body can be acquired through a feedback microphone, and the feedback microphone is disposed on the rear vortex tongue near a noise source to facilitate recording of the first sound during operation of the air conditioner indoor unit body.

[0049] S102: When the first sound spectrum is greater than a preset spectrum, the noise reduction module is turned on to emit an anti-noise sound.

[0050] Specifically, the preset spectrum is the spectrum when the air conditioner is running without noise. It can be understood that when the first sound spectrum is smaller than the preset spectrum, the first sound when the air conditioner body is running is not noise, that is, it will not cause auditory distress to the user. At this time, there is no need to turn on the noise reduction module, and the air conditioner body continues to operate normally.

[0051] When the first sound spectrum is greater than the preset spectrum, the first sound during operation of the air conditioner body is noise, that is, the sound generated by the operation of at least one of the crossflow fan, the electronic expansion valve and the compressor of the air supply system affects the user's hearing. At this time, the noise reduction module is turned on to emit anti-noise sound.

[0052] The information of the anti-noise sound, that is, the anti-noise audio spectrum, can be obtained by processing the audio analysis software. It can be understood that the anti-noise audio spectrum is opposite in phase to the first sound spectrum, so that the anti-noise sound has an effect of canceling the first sound when the air conditioner is running.

[0053] For example, when the sound of the air conditioner is noise and affects the user's hearing, the noise reduction module can be started and stopped according to the user's operation in the control panel. For example, when the user clicks the icon of the noise reduction command in the control panel, the noise reduction module is turned on and the air conditioner enters the noise reduction mode.

[0054] For example, the air conditioner can be connected to a terminal device, and the user can send a command to the air conditioner to start and stop the noise reduction module through the terminal device. For example, the air conditioner can be connected to a mobile phone, and when the user sends a command to turn on the noise reduction module to the air conditioner through the mobile phone, the air conditioner enters the noise reduction mode, and the noise reduction module emits an anti-noise sound to offset the first sound.

[0055] S103: Acquire a second sound spectrum when the air conditioner is in operation.

[0056] Specifically, the anti-noise sound is used to eliminate the first sound when the air conditioner body is running, making the sound emitted by the air conditioner body during operation smaller. It can be understood that after the anti-noise sound eliminates the first sound when the air conditioner body is running, the sound emitted by the air conditioner body during operation is the second sound.

[0057] For example, the sound after cancellation, i.e., the second sound, can be obtained by a feedforward microphone, and the second sound obtained by the feedforward microphone is imported into the audio analysis software, and the audio analysis software converts the second sound data into a spectrogram. The spectrogram shows the energy distribution information of the sound at different frequencies, i.e., the second sound spectrum.

[0058] In a specific implementation, the feedforward microphone is arranged on the rear vortex tongue near the air outlet to facilitate the recording of the second sound after the anti-noise sound is offset by the first sound when the air conditioner body is running.

[0059] In some possible implementations, based on the first sound spectrum and the anti-noise audio spectrum, the anti-noise audio spectrum can be phase-inverted by digital signal processing technology, that is, the waveform in the noise spectrum is flipped upside down to make it completely opposite to the waveform of the first sound spectrum. The anti-noise audio spectrum after phase inversion is superimposed on the first sound spectrum, and the waveforms of the two will interfere with each other, thereby directly obtaining the second sound spectrum when the air conditioner body is running.

[0060] S104. When the second sound spectrum is greater than a preset spectrum, lower the operating parameters of the object of the first sound spectrum, where the operating parameters include at least one of a rotation speed parameter of the air supply system, an opening parameter of the electronic expansion valve, and an operating frequency of the compressor.

[0061] Specifically, when the second sound spectrum is smaller than the preset spectrum, at this time, under the action of the anti-noise module, a good noise reduction effect is achieved, that is, the sound after the anti-noise sound is offset by the first sound when the air conditioner body is running is no longer noise, and will not cause auditory distress to the user, and the air conditioner body can continue to operate normally.

[0062] When the second sound spectrum is greater than the preset spectrum, it can be understood that the sound after the anti-noise sound is offset by the first sound when the air conditioner body is running is still noise, that is, the sound generated by the operation of at least one of the cross-flow fan, electronic expansion valve and compressor of the air supply system will still affect the user's hearing.

[0063] According to step S101, the first sound spectrum is identified, and the object corresponding to the first sound spectrum has been determined. Thus, the operating parameters of the object of the first sound spectrum are adjusted, that is, at least one of the speed parameter of the air supply system, the opening parameter of the electronic expansion valve and the operating frequency of the compressor is lowered to reduce the sound of the air conditioner body during operation.

[0064] For example, the operating parameters of the object of the first sound spectrum can be adjusted according to the user's operation in the control panel. For example, when the user clicks the wind speed icon in the control panel, the speed of the crossflow fan can be controlled, and the whistle sound generated by the speed parameter of the air supply system can be weakened by lowering the speed of the crossflow fan.

[0065] The control method of the air conditioner in the embodiment of the present application obtains the first sound spectrum and the object of the first sound spectrum when the air conditioner body is running; when the first sound spectrum is greater than the preset spectrum, that is, the first sound spectrum is a noise spectrum, the noise reduction module is turned on to emit an anti-noise sound; the second sound spectrum when the air conditioner body is running is obtained, and when the second sound spectrum is greater than the preset spectrum, that is, the anti-noise sound fails to effectively offset the noise, the operating parameters of the object of the first sound spectrum are adjusted. Through the above method, when the anti-noise audio spectrum fails to effectively offset the noise, the operating parameters of the object emitting the noise can be further adjusted, thereby achieving a good noise elimination effect and improving the user experience.

[0066] exist Figure 2 Based on the embodiment shown below, combined with Figure 3 , the control method of the above air conditioner is described in detail.

[0067] Figure 3 A schematic diagram of another air conditioner control method provided in an embodiment of the present application. Figure 3 , the method comprising:

[0068] S201. Acquire a first sound spectrum when an air conditioner is in operation, and an object of the first sound spectrum, wherein the object of the first sound spectrum includes at least one of an air supply system, an electronic expansion valve, and a compressor of the air conditioner.

[0069] It should be noted that the execution process of step S201 can refer to the execution process of step S101, which will not be described in detail here.

[0070] S202: When the first sound spectrum is greater than a preset spectrum, an anti-noise sound signal is generated by a noise reduction chip, and the anti-noise sound signal is received by a speaker array and an anti-noise sound is emitted.

[0071] Specifically, the noise reduction module includes a noise reduction chip and a speaker array. When the first sound spectrum is greater than the preset spectrum, the sound generated when the air conditioner body is in operation is noise, that is, the sound generated when at least one of the cross-flow fan, electronic expansion valve and compressor of the air supply system is in operation affects the user's hearing.

[0072] At this time, a noise reduction chip is used to generate an anti-noise signal that is phase-reversed with the noise. The speaker array is composed of multiple speakers and can emit multiple sound sources at the same time. The speaker array receives the anti-noise sound signal and converts it into a specific sound wave pattern and emits it, which is the anti-noise sound used to eliminate the first sound.

[0073] The anti-noise audio spectrum can be obtained by processing with audio analysis software, which represents the energy distribution of the anti-noise signal at different frequencies.

[0074] S203: Obtain the relative position between the user and the air conditioner body.

[0075] Specifically, by determining the relative position between the user and the air conditioner body, the noise propagation path can be understood and analyzed so that the noise reduction chip can be adjusted to optimize the anti-noise sound signal it generates.

[0076] Exemplarily, the relative position information between the user and the air conditioner body may be determined by a position sensor, for example, information such as the distance of the user relative to the air conditioner body and the angle of the user relative to the air conditioner body.

[0077] S204: Adjust the noise reduction chip according to the relative position and the first sound spectrum to change the volume of the anti-noise sound emitted by the speaker array.

[0078] This step can be understood as changing the size of the anti-noise sound emitted by the speaker array by adjusting the anti-noise sound signal generated by the noise reduction chip according to the relative position information between the user and the air conditioner body and the first sound spectrum.

[0079] In some embodiments, the noise reduction chip includes a filter, and the noise reduction chip is adjusted according to the relative position and the first sound spectrum to change the size of the anti-noise sound emitted by the speaker array, including:

[0080] The parameters of the filter are adjusted, the parameters include the gain of the filter, and the relative position includes the distance and angle of the user relative to the air conditioner body, wherein the distance is inversely proportional to the gain, the angle is proportional to the gain, the size of the first sound spectrum is proportional to the gain; and the gain is proportional to the size of the anti-noise sound.

[0081] Specifically, according to the user's distance and angle relative to the air conditioner body and the first sound spectrum, the gain of the filter is adjusted to adjust the anti-noise sound signal, thereby changing the size of the anti-noise sound emitted by the speaker array. It can be understood that the gain is adjusted to increase when the distance is closer, and to decrease when the distance is farther; the gain is adjusted to increase when the angle is larger, and to decrease when the angle is smaller; the size of the first sound spectrum refers to the difference between the first sound spectrum and the preset spectrum when the first sound spectrum is larger than the preset spectrum. The gain is adjusted to increase when the difference is larger, and to decrease when the difference is smaller;

[0082] It can be understood that increasing the gain of the filter can make the filter suppress the noise signal more strongly, that is, it will enhance the anti-noise sound signal, making the anti-noise sound emitted by the speaker array louder; reducing the gain of the filter can reduce the filter's attenuation of the useful signal, that is, it can weaken the anti-noise sound signal, thereby making the anti-noise sound emitted by the speaker array smaller.

[0083] Exemplarily, when the first sound spectrum is greater than the preset spectrum and the difference between the two becomes larger, and the distance between the user and the air outlet of the air conditioner body becomes closer and the angle increases, the gain of the filter is increased to enhance the anti-noise sound signal, so that the anti-noise sound emitted by the speaker array becomes louder.

[0084] S205: Obtain a second sound spectrum when the air conditioner body is in operation.

[0085] It should be noted that the execution process of step S205 can refer to the execution process of step S103, which will not be described in detail here.

[0086] S206: When the second sound spectrum is greater than a preset spectrum, adjust the operating parameters of the object of the first sound spectrum.

[0087] It should be noted that the execution process of step S206 can refer to the execution process of step S104, which will not be described in detail here.

[0088] The control method of the air conditioner of the embodiment of the present application obtains the relative position of the user and the air conditioner body; according to the relative position and the first sound spectrum, the noise reduction chip is adjusted to change the size of the anti-noise audio spectrum emitted by the speaker array. Furthermore, if the anti-noise audio spectrum fails to effectively offset the noise, the noise is reduced by adjusting the operating parameters of the object emitting the noise, thereby improving the user experience.

[0089] Figure 4 This is a schematic diagram of the structure of the air conditioner control device provided in the embodiment of the present application. Figure 4 The air conditioner control device 30 comprises:

[0090] The first acquisition module 31 is used to acquire a first sound spectrum when the air conditioner is running, and an object of the first sound spectrum, wherein the object of the first sound spectrum includes at least one of an air supply system, an electronic expansion valve and a compressor of the air conditioner.

[0091] The first control module 32 is connected to the first acquisition module 31 and is used to activate the noise reduction module to emit anti-noise sound when the first sound spectrum is greater than a preset spectrum.

[0092] The second acquisition module 33 is used to acquire a second sound spectrum when the air conditioner body is in operation.

[0093] The second control module 34 is connected to the second acquisition module 33, and is used to lower the operating parameters of the object of the first sound spectrum when the second sound spectrum is greater than the preset spectrum, and the operating parameters include at least one of the speed parameter of the air supply system, the opening parameter of the electronic expansion valve and the operating frequency of the compressor.
