Adjusting method and device for air conditioner

Abstract

The invention discloses an adjusting method and device for an air conditioner. The method comprises the steps that after the air conditioner enters a preset work mode, a sound source is detected through a sound source detecting device, and all detected sound source frequencies and corresponding real-time noise values are obtained; noise frequencies of air flow sounds and corresponding real-time noise values are extracted from the obtained sound source frequencies and the real-time noise values, and preset noise threshold values corresponding to the noise frequencies of the air flow sounds are determined; when the real-time noise values of the air flow sounds are smaller than or equal to the corresponding preset noise threshold values, whether the real-time noise values of the air flow sounds are larger than the corresponding standard noise values or not is judged; and when the real-time noise values of the air flow sounds are larger than the corresponding standard noise values, a stepping motor of the air conditioner is adjusted to adjust the air guide angle of an air guide plate. The noise in the running process of the air conditioner is lowered, and then the influence of the noise of the air conditioner on work and life of users is lowered.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a method and device for adjusting the noise of an air conditioner. Background technique [0002] When the existing air conditioner is in operation, it often produces a certain amount of noise due to the different characteristics of each component. When an object vibrates, it forces the air particles around it to move back and forth, causing the air to generate an additional alternating pressure on the atmospheric pressure. The pressure wave generated by this alternating pressure is called a sound wave (alternately generates compression and sparse states to form fluctuations) , when the sound wave with a frequency range of 20-20000Hz reaches the human ear and is received by the human ear, it becomes sound. The irregular combination of sounds of various frequencies and sound intensities is called noise. Broadly speaking, all annoying and unwanted sounds are called noise....
