The filter clogging degree can be severe clogging of the filter screen or clogging of the filter screen. For example, the same type of air conditioner collected in different scenarios. The noise of the filter can be the surge noise caused by the severe blockage of the filter screen, or the surge noise caused by the blockage of the filter screen.

a2, associate the preset audio with a corresponding preset noise type. The association may be that the frequency of each preset audio is associated with the corresponding preset noise type. For example, the preset noise type corresponding to the preset audio frequency less than 500Hz is surge noise, and the preset audio frequency corresponding to 700Hz The default noise type is Rotational Noise.

a3. Establish a noise frequency database, and store a plurality of preset audio frequencies and a preset noise type associated with each preset audio frequency in the noise frequency database.

In some embodiments of the present application, after step 103, it can be detected whether the filter screen has been cleaned. In the embodiment of the present application, there are various ways to detect whether the filter screen has been cleaned. For example, as shown in FIG. 4 , 4 is a schematic flowchart of another embodiment of detecting whether the filter screen has been cleaned in the noise control method for an air conditioner provided by the embodiment of the present application, including steps 401 to 403:

401. Collect first audio data of the air conditioner by using the audio collector again.

Wherein, the first audio data includes the running sound of the air conditioner running according to the increased rotational speed of the fan.

402. Match the first audio data with preset audio in a noise frequency database, and determine whether the first audio data contains surge noise according to a matching result.

In this embodiment of the present application, the matching method between the first audio data and the preset audio in the noise frequency database is similar to the matching method between the audio data and the preset audio in the noise frequency database in step 102, and details are not described herein again.

403. If the first audio data does not contain surge noise, adjust the boosted rotational speed of the fan to the initial rotational speed.

Wherein, the preset demand of the air conditioner includes a preset cooling demand of the air conditioner and a preset heating demand of the air conditioner. In this embodiment of the present application, the temperature difference may be compared with a preset temperature difference threshold, and according to the comparison result, it is judged whether the increased fan speed meets the preset requirements of the air conditioner. Exemplarily, the indoor temperature is taken as the temperature of the air outlet of the air conditioner as For example, the temperature of the air outlet of the air conditioner is obtained through the infrared sensor, the temperature difference between the air outlet temperature of the air conditioner and the preset temperature is calculated, and the absolute value of the temperature difference is compared with the temperature difference threshold. The fan speed does not meet the preset requirements of the air conditioner. If the temperature difference is less than or equal to the temperature difference threshold, it means that the increased fan speed meets the preset requirements of the air conditioner. For example, when the preset demand of the air conditioner is the preset cooling demand of the air conditioner, the temperature difference threshold can be 5°C. If the temperature difference between the air outlet temperature of the air conditioner and the preset temperature is greater than 5°C, it means that the actual cooling of the air conditioner is lower than that of the air conditioner. The preset cooling demand, that is, the increased air conditioner fan speed does not meet the preset cooling demand of the air conditioner, and the air conditioner fan needs to be increased again; if the temperature difference between the air outlet temperature of the air conditioner and the preset temperature is less than or equal to 5°C, the air conditioner The actual cooling of the air conditioner meets the preset cooling demand of the air conditioner, that is, the increased fan speed of the air conditioner meets the preset cooling demand of the air conditioner.

503. If the increased fan speed meets the preset requirement of the air conditioner, control the air conditioner to operate according to the increased fan speed.

504. If the increased fan speed does not meet the preset requirement of the air conditioner, adjust the increased fan speed again.

The re-adjustment of the speed of the fan after the increase may be a second increase of the speed of the fan after the increase.

In the embodiment of the present application, after adjusting the operating parameters of the air conditioner according to the noise type of the air conditioner, it is judged by the temperature difference whether the adjusted operating parameters meet the preset requirements of the air conditioner, so as to reduce the noise during the operation of the air conditioner, Maintain the preset heating/cooling demand of the air conditioner to improve user comfort.

In some embodiments of the present application, in order to better illustrate the noise control method for an air conditioner provided by the embodiment of the present application, an application scenario of the noise control method for an air conditioner is provided, as shown in FIG. 6 , which is an embodiment of the present application for A schematic diagram of an application scenario embodiment of the air conditioner noise control method, the air conditioner noise control method is applied to an air conditioner noise control system, and the air conditioner noise control system includes an air conditioner, an audio collector, an audio analyzer, and an audio memory.
