As shown in fig. 11, the present invention provides a control system of the air purifier, which mainly comprises: the air conditioner comprises a detection module, a fan control module, a command module and an air outlet control module. The detection module is used for detecting the content of PM2.5 in the current environment and converting the content into a detection signal, a standard value (set value) is preset in a program, when the detected content of PM2.5 is greater than the standard value, a second detection signal is output, and if the detected content of PM2.5 is less than (or equal to) the standard value, a first detection signal is output. The fan control module is used for receiving the detection signal and controlling the rotating speed of the fan motor according to the detection signal, when the first detection signal is received, the rotating speed of the fan motor is controlled to be in a first rotating speed state, otherwise, when the second detection signal is received, the rotating speed is controlled to be in a second rotating speed state. The command module is used for receiving an instruction from the outside and converting the instruction into a corresponding command signal, the external command is input through the operation panel, the corresponding command signal is output by pressing the button, when the button for opening the first air outlet channel 1610 is selected to be pressed, a first signal is output, and when the button for opening the second air outlet channel 1620 is selected to be pressed, a second signal is output.
The air outlet control module is used for receiving a command signal and controlling the opening and closing of the first air outlet unit and the second air outlet unit, when the air outlet control module receives a signal I, an electromagnetic valve (a first opening and closing mechanism) in the first air outlet unit (a first air outlet channel) opens a passage, and meanwhile, the second opening and closing mechanism is closed, namely, the motor 1021 in the second air outlet unit (a second air outlet channel) works to drive the cover plate 1624 to move downwards so as to close an opening of the second air outlet channel, so that purified air can only be output through the first air outlet unit, and the fan control module also receives the signal I at the moment and controls the rotating speed of the fan motor to be in a first rotating speed (low rotating speed) state; on the contrary, when the second signal is received by the air outlet control module, the electromagnetic valve (the first opening/closing mechanism) in the first air outlet unit (the first air outlet channel) closes the passage, and simultaneously the second opening/closing mechanism opens and closes, that is, the motor 1021 in the second air outlet unit (the second air outlet channel) operates to drive the cover plate 1624 to move upward so as to open the opening of the second air outlet channel, so that the purified air can only be output through the second air outlet unit, and the fan control module also receives the second signal at this time, and controls the rotation speed of the fan motor to be in the second rotation speed (high rotation speed) state, wherein the priority value of the command signal is greater than the detection signal, that is, the command signal from the command module is preferentially responded, and when the input command is to open the first air outlet channel and the detection module outputs the second detection signal at this time, the fan motor is preferentially in the first rotation speed.
The scope of the present invention is defined not by the above-described embodiments but by the appended claims and equivalents thereof.
