[0030] In order to make the objectives, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be described in detail below with the drawings in the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort belong to the scope of protection of the present application.

[0031] First, it needs to be explained that in the embodiments of the present application, the terms "comprise", "contain" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not explicitly listed, or includes elements inherent to such process, method, article or device. Without more limitations, the element defined by the sentence "comprises a" does not exclude the presence of another identical element in the process, method, article or device comprising the element.

[0032] Secondly, it needs to be explained that in the embodiments of the present application, the words "exemplary" or "for example" are used to represent examples, illustrations or descriptions. Any embodiment or design scheme described as "exemplary" or "for example" in the present application should not be interpreted as more preferred or more advantageous than other embodiments or design schemes. Rather, the words "exemplary" or "for example" are intended to present the relevant concept in a specific way.

[0033] In the related art, an active noise control system for noise reduction of an air conditioner fan includes a sensor configured to monitor characteristics of noise generated by the air conditioner and output a corresponding noise monitoring signal; a control module connected to the sensor, the control module executing an active noise control method, performing noise signal analysis, noise reduction signal calculation, and generating a control signal based on the noise monitoring signal; and a loudspeaker array connected to the control module, the loudspeaker array generating active control sound for canceling the noise generated by the air conditioner based on the control signal, thereby achieving active noise control.

[0034] However, the use of the above control system may result in a situation where the active control sound and the noise emitted by the air conditioner do not cancel each other out, and the noise reduction effect is not good.

[0035] The reason why the active control sound of the above control system and the noise emitted by the air conditioner do not cancel each other out is that:

[0036] The active noise control system of the air conditioner is similar to the active noise reduction scheme of the noise reduction earphone, and both are active noise reduction of the existing noise. However, there is a significant difference between the use environment of the air conditioner and the noise reduction earphone: the noise reduction earphone is close to the ear when in use, which belongs to a closed field environment; while the air conditioner has a certain distance from the user when in use, and the distance changes at any time with the movement of the personnel, that is, the use of the air conditioner is an open field environment.

[0037] For the active noise reduction of the air conditioner, when the standing position of the user 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 cancel each other out will be different. That is, when the user is at a standing position relative to the air conditioner, the human ear will receive sound after the active control sound and the noise completely cancel each other out, and the control system achieves good active noise reduction effect; when the user is at another standing position relative to the air conditioner, the human ear will receive sound after the active control sound and the noise do not completely cancel each other out, and the active noise reduction does not have good noise reduction effect, and noise still exists at this time.

[0038] In view of the above problem, after analyzing the source of the noise generated by the air conditioner, it is found that the whistle caused by the speed parameter of the air conditioner indoor unit air supply system, the refrigerant flow sound caused by the opening parameter of the electronic expansion valve, and the compressor vibration transmission sound caused by the running frequency of the compressor all generate noise during the operation of the air conditioner.

[0039] In the process of active noise reduction, the active control sound emitted by the active control system will be used to cancel any one of the above noises or a combination of several noises. Since the generation of noise is related to the operating parameters of each component in the air conditioner, when the active control sound and the noise do not cancel each other out, the object of the generated noise can be further controlled, that is, the related parameters of the object of the generated noise are adjusted, so that the noise can be reduced.

[0040] Therefore, the application provides a control method, device and equipment of an air conditioner. The air conditioner comprises an air conditioner body and a noise reduction module. Firstly, a first sound spectrum and an object of the first sound spectrum when the air conditioner body is running are obtained. Secondly, 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 started to emit anti-noise sound. Finally, a second sound spectrum when the air conditioner body is running is obtained. When the second sound spectrum is greater than the preset spectrum, that is, the anti-noise sound cannot effectively offset the noise, the running parameter of the object of the first sound spectrum is adjusted. By corresponding the noise and the object emitting the noise, when the anti-noise sound cannot effectively offset the noise, the running parameter of the object emitting the noise can be further adjusted, so that the noise is well eliminated, thereby improving the user experience.

[0041] Figure 1 A connection diagram of the air conditioner body and the noise reduction module is provided for the embodiment of the application. Referring to Figure 1 The air conditioner of the embodiment of the application comprises an air conditioner body 10 and a noise reduction module 20. Exemplarily, the air conditioner body 10 comprises a cross-flow fan 110 and a vortex tongue assembly 120. The vortex tongue assembly 120 comprises 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 in communication with an 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. The arrow lines represent the flow direction of the air.

[0042] Figure 2 A flowchart of a control method of an air conditioner is provided for the embodiment of the application. Referring to Figure 2 The method comprises the following steps.

[0043] In S101, a first sound spectrum when the air conditioner body is running and an object of the first sound spectrum are obtained. The object of the first sound spectrum comprises at least one of a supply air system, an electronic expansion valve and a compressor of the air conditioner body.

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

[0045] Exemplarily, the first sound when the air conditioner body is running can be obtained by a sound sensor. 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 adjacent to the inside of the air conditioner indoor unit body. The noise reduction module is close to the air outlet. In this way, the sound sensor can conveniently capture the first sound when the air conditioner indoor unit body is running.

[0046] Further, the first sound information, i.e. the first sound spectrum, of the air conditioner body in operation can be obtained by audio analysis software. Specifically, the first sound obtained by the sound sensor is introduced into the audio analysis software, and the audio analysis software can convert the first sound data into a spectrum graph. The spectrum graph shows the energy distribution information of the first sound at different frequencies, i.e. the first sound spectrum.

[0047] By observing the first sound spectrum, the energy distribution at different frequencies is analyzed to identify the object of the first sound spectrum. It can be understood that, according to the different energy distribution, the object of the first sound spectrum can be any one of the air supply system, the electronic expansion valve and the compressor, or a combination thereof.

[0048] In some possible embodiments, the first sound of the air conditioner body in operation can be obtained by a feedback microphone. The feedback microphone is arranged on the rear tongue near the noise source to facilitate the recording of the first sound of the air conditioner body in operation.

[0049] S102, when the first sound spectrum is greater than the preset spectrum, the noise reduction module is started to emit anti-noise sound.

[0050] Specifically, the preset spectrum is the spectrum of the air conditioner in noiseless operation. It can be understood that, when the first sound spectrum is less than the preset spectrum, the first sound of the air conditioner body in operation is not noise, i.e. it does not cause auditory disturbance to the user. At this time, the noise reduction module does not need to be started, and the air conditioner body continues to operate normally.

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

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

[0053] For example, when the user clicks the icon of the noise reduction instruction in the control panel, the noise reduction module is started, and the air conditioner enters the noise reduction mode.

[0054] For example, the air conditioner can be connected with a terminal device, and the user sends a control instruction to the air conditioner through the terminal device to start or stop the noise reduction module. For example, the air conditioner can be connected with a mobile phone, and when the user sends an instruction to the air conditioner through the mobile phone to start the noise reduction module, the air conditioner enters the noise reduction mode, and the noise reduction module emits anti-noise sound to cancel the first sound.

[0055] S103, acquiring a second sound spectrum when the air conditioner body is running.

[0056] Specifically, the anti-noise sound is used to eliminate the first sound when the air conditioner body is running, so that the sound emitted by the air conditioner body when it is running becomes smaller. It can be understood that after the anti-noise sound eliminates the first sound when the air conditioner body is running, the sound at this time is the second sound.

[0057] For example, the second sound after cancellation can be obtained by the feed-forward microphone, that is, the second sound obtained by the feed-forward microphone is introduced into the audio analysis software, and the audio analysis software converts the second sound data into a spectrum graph. The spectrum graph shows the energy distribution information of the sound at different frequencies, that is, the second sound spectrum.

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

[0059] In some possible implementations, according to the first sound spectrum and the anti-noise sound spectrum, the anti-noise sound spectrum can be phase-inverted by a digital signal processing technology, that is, the waveform in the noise spectrum is flipped up and down to make it completely opposite to the waveform of the first sound spectrum. After phase inversion, the anti-noise sound spectrum and the first sound spectrum are superimposed, and the waveforms between them interfere with each other, and then the second sound spectrum when the air conditioner body is running is directly obtained.

[0060] S104, when the second sound spectrum is greater than a preset spectrum, the running parameter of the object of the first sound spectrum is lowered, and the running parameter includes at least one of the rotation speed parameter of the air supply system, the opening parameter of the electronic expansion valve, and the running frequency of the compressor.

[0061] Specifically, when the second sound spectrum is less than the preset spectrum, at this time, under the action of the anti-noise module, good noise reduction effect is achieved, that is, the sound after the anti-noise sound cancels the first sound when the air conditioner body is running is no longer noise, and will not cause auditory disturbance to the user, and the air conditioner body can continue to run 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 cancels out the first sound when the air conditioner body is running is still noise, that is, the sound generated by at least one of the cross-flow fan of the air supply system, the electronic expansion valve, and the press machine running still affects the user's hearing.

[0063] According to step S101, the first sound spectrum is identified, and it has been determined that the object corresponding to the first sound spectrum, so that by adjusting the running parameter of the object of the first sound spectrum, that is, at least one of the rotation speed parameter of the air supply system, the opening parameter of the electronic expansion valve, and the running frequency of the press machine is lowered, to weaken the sound when the air conditioner body is running.

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

[0065] The control method of the air conditioner of the embodiment of the application obtains the first sound spectrum when the air conditioner body is running and the object of the first sound spectrum; 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 started to emit 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 cannot effectively cancel out the noise, the running parameter of the object of the first sound spectrum is adjusted. Through the above method, when the anti-noise sound spectrum cannot effectively cancel out the noise, the running parameter of the object emitting the noise can be further adjusted, the good elimination effect of the noise is realized, and the user experience is improved.

[0066] In Figure 2 On the basis of the embodiment shown, the following will be combined Figure 3 The control method of the air conditioner is described in detail.

[0067] Figure 3 Another control method of an air conditioner provided by the embodiment of the application is shown in the schematic diagram. Referring to Figure 3 The method comprises:

[0068] S201, obtaining the first sound spectrum when the air conditioner body is running, and the object of the first sound spectrum, the object of the first sound spectrum comprising at least one of the air supply system, the electronic expansion valve, and the press machine of the air conditioner body.

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

[0070] S202, generating an anti-noise sound signal through the noise reduction chip when the first sound spectrum is greater than the preset spectrum, receiving the anti-noise sound signal through the loudspeaker array and emitting the anti-noise sound.

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

[0072] At this time, the anti-noise signal phase-inverted with the noise is generated through the noise reduction chip. The loudspeaker array is composed of multiple loudspeakers and can emit multiple sound sources at the same time. The loudspeaker array receives the anti-noise sound signal and converts it into a specific sound wave mode and emits it, that is, the anti-noise sound for eliminating the first sound.

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

[0074] S203, obtaining the relative position of 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 as to adjust the noise reduction chip and optimize the anti-noise sound signal generated by the noise reduction chip.

[0076] For example, the relative position information of the user and the air conditioner body can be determined by a position sensor, 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, adjusting the noise reduction chip according to the relative position and the first sound spectrum to change the size of the anti-noise sound emitted by the loudspeaker array.

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

[0079] In some embodiments, the noise reduction chip includes a filter. 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 loudspeaker array, including:

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

[0081] Specifically, according to the distance and angle of the user 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, so as to change the size of the anti-noise sound emitted by the loudspeaker array. It can be understood that the closer the distance, the greater the adjusted gain; the greater the angle, the greater the adjusted gain; the greater the difference between the first sound spectrum and the preset spectrum, the greater the adjusted gain.

[0082] It can be understood that increasing the gain of the filter can make the filter stronger in suppressing the noise signal, that is, the anti-noise sound signal will be enhanced, so that the anti-noise sound emitted by the loudspeaker array becomes larger; reducing the gain of the filter can reduce the weakening of the useful signal by the filter, that is, the anti-noise sound signal can be weakened, so that the anti-noise sound emitted by the loudspeaker array becomes smaller.

[0083] For example, when the first sound spectrum is greater than the preset spectrum and the difference between them 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 loudspeaker array becomes larger.

[0084] S205, acquiring a second sound spectrum when the air conditioner body is running.

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

[0086] S206, adjusting the running parameter of the object of the first sound spectrum when the second sound spectrum is greater than the preset spectrum.

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

[0088] The control method of the air conditioner of the embodiment of the application, by acquiring 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 sound spectrum emitted by the loudspeaker array. Further, if the anti-noise sound spectrum cannot effectively offset the noise, the running parameter of the object emitting the noise is adjusted to reduce the noise, thereby improving the user's experience.

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