Based on above-mentioned hardware architecture, the embodiment of the control method of the air condition of that present invention is proposed.
It is the first embodiment of the control method of the air condition of that present invention, the control method of the air conditioner referring to Fig. 2, Fig. 2
The following steps are included:
Step S10, in real time or timing acquisition described in noise transducer acquisition level of noise；
In the present invention, air conditioner can be cabinet-type air conditioner, can be on-hook.By taking cabinet-type air conditioner as an example, referring to Fig. 3 and Fig. 4, air-conditioning
Device includes the front panel 11 of shell 10 and setting inside the shell, and shell 10 is equipped with air outlet 110, and front panel 11 also is provided with outlet air
Mouth (not indicating), two air outlets are oppositely arranged；Counter-rotating fan 12 is set in air duct, and the air outlet 110 of shell 10 is arranged in
And between the air outlet of front panel 11；It, can on the tubular structure in addition, two settable tubular structures of air outlet (not indicating)

The distance between air outlet 110 of 12b, preposition wind wheel 12a and shell 10 be greater than between postposition wind wheel and air outlet 110 away from
From.
At runtime, at runtime, since two wind wheels are oppositely arranged, and two wind wheels turn counter-rotating fan counter-rotating fan
Move it is contrary so that counter-rotating fan generate eddy effect so that air generate vibration, to generate biggish noise.
After structural parameters of the inventor to counter-rotating fan are tested, discovery has the relative distance between two wind wheels to level of noise
Have an impact, obtain after tested: in a certain distance section, when the distance between two wind wheels are bigger, what air conditioner generated makes an uproar
Value is smaller.
In addition, the blade angle of wind wheel also will affect the generation of the level of noise of counter-rotating fan, it is the leaf of wind wheel referring to Fig. 5, α
Piece angle, angle of the blade angle between the first plane and the second plane, the angle are acute angle, and the first plane is blade (leaf
Piece is curved surface) section, and the rotary shaft of blade is located in the first plane, and the second plane is perpendicular flat of wind wheel rotary shaft
Face.After tested, in certain blade angle section, blade angle is smaller, and the level of noise that counter-rotating fan generates is smaller.
Based on above-mentioned discovery and test, air conditioner can reduce making an uproar for air conditioner generation by the structural parameters of counter-rotating fan
Value.Therefore when air conditioner is run, start sensor noise, thus the noise of real-time or timing acquisition sensor noise acquisition
Value.
Step S20, judges whether the level of noise meets noise reduction condition；
After getting level of noise, air conditioner judges whether level of noise meets noise reduction condition.Specifically, air conditioner judges
Whether level of noise is greater than target noise value, if level of noise is greater than target noise value, then determines that level of noise meets target noise value.
It should be noted that target noise value is determined according to the preset threshold stored in air conditioner.Specifically, air conditioner is sentenced
Whether disconnected current slot is in preset time period, and preset time period can be by user setting, the corresponding environment of the preset time period
It is set as quiet environment, preset time period can be sleep period, if current slot is in preset time period, by air-conditioning
The first preset threshold stored in device is as target noise value, and the first preset threshold can be any appropriate numerical value, and first
The corresponding decibel of preset threshold is smaller；If current slot is not preset time period, by the second default threshold of air conditioner storage
Value is used as target noise value, and the second preset threshold is greater than the first preset threshold.In addition, target noise value can also be by the state of user
Determine, in this regard, store preset state in air conditioner, preset state can be sleep state, air conditioner can by itself
Camera is come the state of the user determined, or the sleep detector by communicating to connect with air conditioner determines the shape of user
State, if the state of user is preset state, then using third predetermined threshold value as target noise value, if the state of user is not
When preset state, then using the 4th preset threshold as target noise value, the 4th preset threshold is greater than third predetermined threshold value, and third is pre-
If the corresponding decibel value of threshold value is smaller, allow the user in quiet environment.
User is in being in noisy environment, if the level of noise that air conditioner generates is less than the corresponding level of noise of noisy environment
When, influence of the noise that air conditioner generates to user is smaller；It is understood that the level of noise that only air conditioner generates is greater than ring
Border noise, the level of noise that air conditioner generates just can generate biggish noise pollution to user.In this regard, air conditioner can pass through environment
Level of noise and the level of noise of sensor noise acquisition judge whether level of noise meets noise reduction condition.Specifically, being set in room
There is sensor noise, which connect with air conditioner signals, and air conditioner is made an uproar by the sensor noise to obtain environment
Value, so that the noise difference (the first noise difference) between the level of noise and environmental noise value of air conditioner generation is calculated, if
The noise difference is greater than preset difference value, and air conditioner then determines that level of noise meets noise reduction condition.
Step S30 adjusts the structural parameters of the counter-rotating fan when the level of noise meets noise reduction condition, to reduce
The level of noise that the air conditioner generates, wherein structural parameters adjusted are in pre-set interval, and the structural parameters include wind wheel
Blade angle and the distance between two wind wheels；
When level of noise meets noise reduction condition, air conditioner adjusts the structural parameters of counter-rotating fan, specifically, being reduced at least one
The blade angle of a wind wheel perhaps increases the relative distance between two wind wheels or is reduced at least the blade angle of a wind wheel
It spends and increases the relative distance between two wind wheels.It should be noted that the structural parameters after adjusting are in corresponding parameter region
Between.In addition, can refer to the drop that following steps carry out level of noise when the structural parameters of counter-rotating fan include the blade angle of wind wheel
It is low；
The level of noise of air conditioner is reduced by wind speed round, and there are four types of schemes, are respectively as follows:
Scheme 1, the blade angle for reducing postposition wind wheel, the blade angle of preposition wind wheel are constant；
Scheme 2, the blade angle for reducing preposition wind wheel, the blade angle of postposition wind wheel are constant；
Scheme 3, the blade angle for reducing preposition wind wheel Yu postposition wind wheel simultaneously；
The revolving speed of preposition wind wheel is reduced to minimum blade angle, and improves the blade angle of postposition wind wheel by scheme 4.
Air conditioner can optionally one of scheme to reduce the level of noise of air conditioner generation.
Air conditioner can gradually adjust the structural parameters of counter-rotating fan, to gradually decrease the level of noise of air conditioner.Alternatively, empty
