Based on the hardware framework, the embodiment of the invention provides the dust deposition detection method for the filter screen of the air conditioner.
Referring to fig. 2, a schematic flow chart of a first embodiment of a method for detecting dust accumulated on a filter screen of an air conditioner according to the present invention includes:
step S10, acquiring the wind noise value of the air outlet of the air conditioner acquired by the sound acquisition device;
in the invention, the air conditioner is an air conditioner with an intelligent voice control function, a sound collection device is arranged in the air conditioner, the sound collection device can comprise a microphone, a sound sensor and a sound sensitive sensor, specifically, the sound collection device is a microphone, the microphone is arranged on a control panel of the air conditioner, and the microphone is used for collecting a control instruction of a user and a wind noise value at an air outlet of the air conditioner. It can be understood that microphones specially used for detecting the wind noise value of the air outlet of the air conditioner can be arranged on the left side and the right side of the air outlet of the air conditioner, so that the accuracy of detecting the wind noise value of the air outlet is improved.
Step S20, acquiring a preset wind noise threshold;
the preset wind noise threshold value is a wind noise extreme value of the air outlet of the air conditioner at the air outlet of the air conditioner under certain dust, and the preset wind noise threshold value is obtained by detecting the rotating speed of an indoor fan after the air conditioner operates stably. For example, under the condition that the air outlet speed of the air conditioner is constant, the wind noise threshold corresponding to 25% of dust accumulated on the filter screen is smaller than the wind noise threshold corresponding to 50% of dust accumulated on the filter screen. In the invention, a plurality of wind noise threshold values can be set, wherein the wind noise threshold values under the conditions of different wind speeds and different dust amounts can be obtained by a user through experiments.
It should be noted that the step of obtaining the preset wind noise threshold specifically includes obtaining a rotation speed of an indoor fan of the air conditioner, and then obtaining the wind noise threshold according to the rotation speed, where the wind noise threshold may include wind noise thresholds corresponding to the filter screens with different dust amounts, for example, the wind noise threshold includes a wind noise threshold corresponding to 50% of dust on the filter screen, the wind noise threshold includes a wind noise threshold corresponding to 75% of dust on the filter screen, and the wind noise threshold includes a wind noise threshold corresponding to 100% of dust on the filter screen, and that accumulation of 100% of dust on the filter screen indicates that the filter screen is full of dust. It can be understood that the larger the rotation speed of the indoor fan of the air conditioner is, that is, the larger the wind speed of the air outlet of the air conditioner is, the wind easily passes through the indoor environment of the filter screen flow passage, and at this time, the larger the wind noise threshold corresponding to the rotation speed is.
Specifically, the step of obtaining the wind noise threshold according to the rotating speed is to firstly determine a wind speed gear of the air conditioner according to the rotating speed of the indoor fan, and obtain a wind speed gear of the air conditioner according to the operating parameters of the indoor fan, where the wind speed gear includes 1 gear, 2 gears, and 3 gears, and the larger the rotating speed of the indoor fan is, the higher the wind speed gear of the air conditioner is. Then acquiring a wind noise threshold corresponding to the wind speed gear, for example, the wind noise threshold of a full filter screen is 35dB when the wind speed gear is 1 gear; when the wind speed is 2, the wind noise threshold value of the dust full of the filter screen is 45 dB; and when the wind speed is 3 grades, the wind noise threshold value of the full dust of the filter screen is 50 dB. It can be understood that after the wind speed gear of the air conditioner is determined, the wind noise threshold of the filter screen under different dust conditions can be obtained according to the mapping relation. In the embodiment of the invention, the corresponding wind noise threshold value is obtained according to the wind speed gear, so that the problem of error in obtaining the wind noise threshold value caused by the fluctuation of the rotating speed of the indoor fan is avoided, and the accuracy of the obtained wind noise threshold value is improved.
Step 30, judging whether the wind noise value is smaller than the wind noise threshold value;
and comparing the wind noise value of the air outlet acquired by the sound acquisition device with a preset wind noise threshold value, and judging the size relation between the wind noise value and the wind noise threshold value.
And step S40, when the wind noise value is smaller than the wind noise threshold value, determining that dust is accumulated on a filter screen of the air conditioner.
In the embodiment of the invention, when the wind noise value is smaller than the wind noise threshold value, the dust accumulation of the filter screen of the air conditioner is considered, and the dust accumulation of the filter screen is judged according to the wind noise threshold value smaller than the wind noise value. For example, when the wind noise value is smaller than the wind noise threshold value when the dust deposition on the filter screen is 25%, the dust deposition amount on the filter screen of the air conditioner is considered to be 25%; when the wind noise value is smaller than the wind noise threshold value when the dust deposition of the filter screen is 50%, the dust deposition amount on the filter screen of the air conditioner is considered to be 50%; and when the wind noise value is smaller than the wind noise threshold value when the dust accumulation of the filter screen is 10%, the filter screen of the air conditioner is considered to be full of dust.
In the technical scheme that this embodiment provided, the air conditioner passes through the wind of the air outlet department of sound collection device collection air conditioner and makes an uproar the value, then make an uproar the value with the wind of predetermineeing and make an uproar the threshold value and compare the wind of gathering, when the wind of gathering makes an uproar the value and is less than the wind threshold value of making an uproar, the air-out of surface filter screen is not unobstructed, then judge how much dust deposition on the filter screen, whether the dust deposition caused the phenomenon of judging the mistake when avoiding the use through the air conditioner long come to judge the filter screen, improve the accuracy of judging how much dust deposition on the filter screen, improve the user and experience the use.

step S50, acquiring the continuous operation duration of the air conditioner;
step S60, judging whether the continuous operation time length is longer than a preset time length;
and when the continuous operation time length is longer than the preset time length, executing the step S10, namely acquiring the wind noise value of the air outlet of the air conditioner acquired by the sound acquisition device.
In the technical scheme provided by this embodiment, in the using process of the intelligent voice air conditioner, in order to improve the accuracy of the wind noise threshold value obtained by the air conditioner, the wind noise value at the air outlet of the air conditioner is usually collected by the sound collection device after the air conditioner operates stably. Meanwhile, in the process of initial operation of the air conditioner, a large amount of dust is not accumulated on the filter screen generally, and at the moment, the default air conditioner does not need to detect the dust accumulation amount on the filter screen. After the air conditioner operates for a period of time, acquiring the continuous operation time of the air conditioner, comparing the continuous operation time with the preset time, and when the continuous operation time is longer than the preset time, determining that dust is possibly accumulated on a filter screen of the air conditioner, executing step S10, namely acquiring the wind noise value of the air outlet of the air conditioner, which is acquired by the sound acquisition device. And then comparing the wind noise value with a wind noise threshold value, and according to the dust accumulation amount on the filter screen corresponding to the wind noise threshold value, realizing a scheme of accurately judging the dust accumulation amount on the filter screen.

The reminding information comprises a dust quantity indicating lamp or a reminding message of sending the dust quantity to the mobile terminal of the user by the air conditioner. For example, when the wind speed gear is 1 gear and the wind noise value is less than 35dB, controlling a dust fullness prompting lamp on a display panel of the air conditioner to be on; when the wind speed gear is 2 and the wind noise value is less than 45dB, controlling a dust fullness prompting lamp on a display panel of the air conditioner to be on; and when the wind speed gear is 3 gears and the wind noise value is less than 50dB, controlling a dust full prompt lamp on a display panel of the air conditioner to be on.

For example, when the wind speed of the air conditioner is in the 1 st gear, and the detected wind noise value of the air outlet is in the wind noise value interval with 50% of dust deposition on the filter screen, the indicator lamp for controlling 50% of dust amount on the control panel of the air conditioner is turned on; when the wind speed of the air conditioner is 1, and the detected wind noise value of the air outlet is in a wind noise value interval with 75% of dust deposited on the filter screen, an indicator lamp for controlling 75% of dust amount on a control panel of the air conditioner is turned on; when the wind speed of the air conditioner is 1 grade and the detected wind noise value of the air outlet is within the wind noise value interval of 100% of the dust deposited on the filter screen, controlling a dust full indicator lamp on a control panel of the air conditioner to be on.
