Detailed Description
In order that the above objects, features and advantages of the invention will be readily understood, a more particular description of the invention will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings.
Embodiment one:
in a specific embodiment, referring to fig. 1, a control method of an air conditioner includes:
step S100: controlling the air conditioner to operate according to a target operation mode, detecting the noise of the air conditioner in the operation mode, and obtaining a noise characteristic value of the air conditioner in the operation mode;
step S200: obtaining a noise analysis result according to the noise characteristic value;
step S300: obtaining a regulation and control instruction according to a noise analysis result and a pre-stored noise frequency spectrum;
step S400: and controlling the operation of the air conditioner according to the regulation and control instruction.
In this embodiment, the control method of the air conditioner is to control the air conditioner to operate according to the target mode, determine the main source of noise by detecting the noise condition analysis in the target operation mode, and further form the regulation command to the air conditioner, control the air conditioner to operate according to the regulation command, and reduce the noise.
Common air conditioner noise sources are: the compressor runs, the indoor unit rotates, the outdoor unit rotates and the air deflector supplies air. When the air conditioner is used, in different operation modes of the air conditioner, the working modes of the compressor, the internal machine, the external machine and the air deflector are different, and noise with different intensities or frequency bands can be generated. When the air conditioner operates, the noise is detected to be larger, and the set normal noise volume is exceeded, so that the noise is caused in the operation process of the air conditioner. At this time, noise detection is required, and the source of the noise is specifically determined by detecting the working states of the compressor, the internal and external machines and the air deflector on the air conditioner.
When detecting that there is a change in the operation state of the main portion of the air conditioner that generates noise, step S100 is performed to further detect and determine whether the main portion is the main source of noise. For example, after the air conditioner is operated, the noise is detected to be large, and when the air conditioner detects that the frequency of the compressor is changed during operation, the compressor may be a main source of noise, and further detection and judgment are needed through step S100. Step S100 is specific: the air conditioner is controlled to operate according to the target operation mode, the original operation mode of the air conditioner is changed, and the air conditioner is operated according to the target operation mode set in the air conditioner. The target operation mode can facilitate the analysis and judgment of the noise source of the air conditioner. The noise of the air conditioner in the target operation mode is detected, and the noise characteristic value of the air conditioner in the operation mode is obtained, so that the noise condition in the target operation mode is judged, and further analysis and judgment of the noise source are facilitated. The noise characteristic value can accurately and scientifically judge the noise condition, and can be the noise volume, the variation value of the noise volume, the frequency band, the frequency and other characteristic values of the noise. The target operation modes can be multiple, and each target operation mode can be convenient for the air conditioner to detect noise at different positions or noise under different operation conditions. By performing noise detection on a plurality of target operating modes, the main source of noise can be finally screened out.
After obtaining the noise characteristic value in the target operation mode, step S200 is performed to analyze the noise characteristic value, so as to obtain a noise analysis result in the target operation mode. The noise characteristic values obtained in the target operation mode are multiple, the multiple noise characteristic values are comprehensively analyzed, and finally an analysis result is obtained. When a plurality of target operation modes exist, an analysis result under each target operation mode is obtained, and then the analysis result under each target operation mode is comprehensively compared and analyzed to obtain a final analysis result.
The analysis result obtained in step S200 can express the comprehensive characteristics of noise in the target operation mode. In step S300, the analysis result is compared with a pre-stored noise spectrum. There are a plurality of pre-stored noise spectrums, which are spectrums of common noise in an air conditioner, and noise sources of these common noise spectrums are already known. Therefore, by comparing the analysis result with the pre-stored noise spectrum, if the analysis result is matched with a certain pre-stored noise spectrum, the corresponding noise source can be obtained by the pre-stored noise spectrum matched with the analysis result, and then the noise source is detected.
After knowing the noise source, steps S300 and S400 are required to be performed, and the air conditioner needs to determine a corresponding regulation command according to the noise source to adjust the operation mode of the air conditioner, adjust the operation state of the noise source, and further reduce the noise. The regulation command in step S300 can recommend a preferred regulation command to the user according to the comparison result of the analysis result and the pre-stored noise spectrum, and can determine the regulation command according to the autonomous selection of the user. After determining the corresponding regulation command, step S400 is performed, and the air conditioner controls to execute the corresponding command according to the regulation command.
In the present embodiment, the control method of the air conditioner can reduce the generation of noise from the source. And the main cause of the noise of the air conditioner can be judged by controlling the air conditioner according to different target operation modes, and the noise can be reduced in a targeted manner when the operation mode of the air conditioner is adjusted subsequently.
Embodiment two:

the first target operation mode is as follows:
step S111: controlling the frequency of a compressor of the air conditioner to be increased to a first frequency according to a first rate;
step S112: after the compressor frequency reaches the first frequency, the compressor frequency is controlled to be reduced to the second frequency according to the first rate.
In this embodiment, the first target operation mode is one of a plurality of target operation modes. The first target operation mode mainly comprises the steps of controlling the operation of the compressor, detecting and judging the noise condition of the compressor during operation, and obtaining a corresponding noise characteristic value. Thereby determining whether the compressor is a major source of noise in a subsequent step. Wherein, when the first target operation is performed, the operation mode of other parts of the air conditioner is maintained unchanged, and the first target operation mode only controls the operation of the compressor to be changed.
Specifically, the first target operation mode is: proceeding to step S111, the compressor frequency is first controlled to increase and the compressor frequency is increased according to the set first speed V 1 Up to the first frequency, in which process the compressor frequency is increased by δh. In the process, noise generated when the compressor is increased in frequency is detected, and corresponding characteristic values are obtained. After reaching the first frequency, step S112 is performed to start down-conversion at the first rate and down-convert to the second rate, where the compressor frequency is reduced by a factor of 2 δh. In the process, noise generated when the compressor is in down-conversion is detected, and corresponding characteristic values are obtained. The first rate is uniform frequency up and uniform frequency down in the frequency up and down processes.
The first target operation mode is carried out by controlling the air conditioner, so that the noise condition of the compressor in the processes of frequency rising and frequency falling can be detected, corresponding noise characteristic values in each section of process can be obtained, and the follow-up step is convenient to further judge whether the noise source comes from the operation of the compressor.

step S122: and continuously controlling the rotation speed of the indoor unit to sequentially reduce the rotation speed according to the third rotation speed, the fourth rotation speed, the fifth rotation speed and the sixth rotation speed.
In this embodiment, the second target operation mode is one of a plurality of target operation modes. The rotation of the motor in the indoor unit is generally a main noise source of the indoor unit. The second target operation mode is mainly used for controlling the operation of the indoor unit, detecting and judging the noise condition of the motor in the indoor unit when the motor rotates, and obtaining a corresponding noise characteristic value. So as to judge whether the motor rotation in the indoor unit is the main source of noise in the subsequent steps. And when the second target operation is carried out, the operation modes of other parts of the air conditioner are kept unchanged, and the second target operation mode only controls the rotation of the indoor unit motor to change.
Specifically, the second target operation mode is: step S121 is performed, in which the indoor unit motor is first controlled to increase the rotation speed based on the original rotation speed, and the rotation speed is sequentially increased according to the set first rotation speed and second rotation speed. The first rotating speed is increased by 50, the second rotating speed is increased by 100, noise generated when the indoor motor is increased is detected in the process, and corresponding characteristic values are obtained. After the rotation speed of the motor of the indoor unit is increased, step S122 is performed, and the rotation speed starts to be reduced according to the third rotation speed, the fourth rotation speed, the fifth rotation speed and the sixth rotation speed. The third rotation speed is reduced by 50 rotation, the fourth rotation speed is reduced by 100 rotation, the fifth rotation speed is reduced by 150 rotation, the sixth rotation speed is reduced by 200 rotation, noise generated when the indoor motor is reduced in rotation is detected in the process, and corresponding characteristic values are obtained.

The rotation of the motor in the outdoor unit is generally a main noise source of the outdoor unit. The third target operation mode is mainly used for controlling the operation of the outdoor unit, detecting and judging the noise condition when the motor in the outdoor unit rotates, and obtaining a corresponding noise characteristic value. Thus, in the following steps, whether the motor rotation in the outdoor unit is the main source of noise is judged. And when the third target operation is performed, the operation modes of other parts of the air conditioner are kept unchanged, and the third target operation mode only controls the rotation of the outdoor unit motor to change.

In the noise detection process, the air conditioner is controlled to operate according to the second target mode and then to operate according to the third target mode, so that the noise of the indoor unit is detected, the indoor unit is arranged indoors, and the influence of the noise intensity on a user is larger.
Fifth embodiment:
in a specific embodiment, the method for controlling the air conditioner to operate according to a target operation mode, detecting noise of the air conditioner in the target operation mode, and obtaining a noise characteristic value of the air conditioner in the target operation mode specifically includes:
step S140: controlling the air conditioner to operate according to a fourth target operation mode, and continuously detecting the noise of the air conditioner in the fourth target operation mode to obtain a noise characteristic value of the air conditioner in the fourth target operation mode;
the fourth target operation mode is as follows:
step S141: controlling the wind sweeping angle of the wind deflector to rise according to the first angle and the second angle in sequence;
step S142: continuously controlling the wind sweeping angle of the wind deflector to sequentially reduce the angle according to the third angle, the fourth angle, the fifth angle and the sixth angle.
In this embodiment, the fourth target operation mode is one of a plurality of target operation modes. The wind sweeping angle of the wind deflector is generally a main noise source of the indoor unit, and if the air outlet caused by the wind sweeping angle is better blown to a certain object capable of generating noise, the noise can be generated, and the use of a user is affected. The fourth target operation mode mainly comprises the steps of controlling the wind sweeping angle of the wind deflector, detecting and judging the noise condition when the wind sweeping angle of the wind deflector is changed, and obtaining a corresponding noise characteristic value. Therefore, in the subsequent step, whether the change of the wind sweeping angle of the wind deflector is a main source of noise is judged. And when the fourth target operation is performed, the operation modes of other parts of the air conditioner are kept unchanged, and the fourth target operation mode only controls the change of the wind sweeping angle of the wind deflector.

Example six:
in a specific embodiment, the air conditioner has at least two operating parameters, and in the target operating mode, the air conditioner maintains one of the at least two operating parameters continuously variable and maintains other operating parameters other than the one operating parameter unchanged.
In this embodiment, the air conditioner operates with at least two operating parameters, for example, during the operation of the air conditioner: the compressor keeps running, and one running parameter corresponds to the compressor; the air guide plate keeps running, and a running parameter corresponding to the running of the air guide plate is also provided; the indoor motor rotates, and corresponding operation parameters and the like are also corresponding to the rotation of the indoor motor. When in a target operating mode, it means that when the air conditioner is operated, one of the operating parameters is kept operating, and the remaining operating parameters are kept inconvenient.

Embodiment seven:
in a specific embodiment, the number of target operating modes is a plurality;
according to the noise characteristic value, obtaining a noise analysis result specifically comprises:
step S210: comparing each noise characteristic value in each target operation mode in the operation of a plurality of target operation modes respectively to obtain corresponding each noise analysis result in each target operation mode respectively;
