Description

Air conditioner, control method, control device and storage medium Technical Field The present invention relates to the technical field of air conditioners, and more particularly, to an air conditioner, a control method, a control device and a computer readable storage medium. Background In the related art, an air conditioner is mounted with a combustible refrigerant. However, according to the safety requirements of the air conditioner, when the refrigerant leaks from the indoor side of the air conditioner, the electric auxiliary heating temperature of the air conditioner cannot exceed 700 ℃ and the concentration of the combustible refrigerant around the potential ignition power device of the air conditioner needs to be ensured to be lower than the lower ignition limit concentration of 75%. At present, when the air conditioner is normally used, the indoor fan is started, so that enough airflow in the air duct can take away the heat of electric auxiliary heat, the surface temperature of the air duct is continuously lower than 700 ℃, and simultaneously, the refrigerant can be taken away, so that the concentration of the refrigerant around the potential ignition power device is continuously lower than a required concentration value. However, when the indoor fan fails, the leaked refrigerant cannot be taken away, so that the safety requirements of the air conditioner cannot be met, and the air conditioner fires and explodes. Disclosure of Invention The air conditioner, the control method, the control device and the computer readable storage medium can solve the problem that when an indoor fan of the air conditioner fails, the refrigerant which is easy to cause arc ignition leakage and is generated by an electrified component is exploded. The air conditioner comprises an indoor fan, an electrified component and a wind pressure detection component, wherein the indoor fan is communicated with the electrified component through a first wind channel, and the wind pressure detection component is configured to collect first wind pressure of the indoor fan and second wind pressure of the first wind channel and control the electrified component to be electrified and powered off according to the difference value of the first wind pressure and the second wind pressure. Therefore, the wind pressure switch is arranged between the wind pressure detection assembly and the charging component, so that the wind pressure switch can detect the pressure difference in the first air channel, when the pressure difference is detected to be reduced, the indoor fan is indicated to be faulty, the air flow blown out by the indoor fan cannot be cooled down for the charging equipment and take away leaked refrigerants, and the charging component is controlled to be powered off through the wind pressure switch, so that the charging component can be prevented from igniting the refrigerants to explode due to electrification and ignition. In some embodiments, the charging member is controlled to be powered on when a difference between the first wind pressure and the second wind pressure is greater than a preset value, and the charging member is controlled to be powered off when a difference between the first wind pressure and the second wind pressure is less than or equal to a preset value. Therefore, by comparing the difference value of the first wind pressure and the second wind pressure with the preset value, whether the indoor fan fails or not can be determined according to the comparison result, and the live-line component is rapidly controlled to be powered off under the condition of failure. In certain embodiments, the preset value is from 25 Pa to 60 Pa in magnitude. Therefore, whether the indoor fan fails or not can be timely and accurately reflected by setting the preset value between 25 Pa and 60 Pa. When the preset value is set to be less than 25 Pa, the preset value is too small, so that the indoor fan cannot be detected to be faulty in time, the electrification of the electrified component cannot be disconnected in time, explosion is easy to cause, and when the preset value is set to be less than 60 Pa, misjudgment is easy to cause during normal operation of the indoor fan, the electrified component is powered off, and normal use of the air conditioner is affected. In some embodiments, the wind pressure detection assembly includes a wind pressure switch disposed in the first wind channel and electrically connected to the charging member, the wind pressure switch configured to control power on and power off of the charging member according to a difference between the first wind pressure and the second wind pressure. Therefore, the wind pressure switch is used as a wind pressure detection assembly to detect wind pressure and control the electrification and outage of the electrification component, so that the mechanical wind pressure switch does not need to be controlled by other controllers, the time for sending and receiving control i
