and step S1, acquiring signals acquired by the human body detection module, and judging whether a human body approaches the clothes airing machine or not according to the acquired signals.

Specifically, the human body detection module collects human body detection signals by using the human body induction sensor, and transmits the collected human body detection signals to the MCU controller, and the MCU controller determines whether a human body approaches the clothes drying machine according to the received human body detection signals.

And step S2, when no human body is detected to approach the clothes airing machine, the MCU controller sends a drive chip enable control signal EN to the illumination drive module to control illumination to be turned off, sends a motor rising control signal M _ UP to the integrated driver, amplifies the motor rising control signal M _ UP by the integrated driver, outputs a motor rising signal M _ UP _ ON to the motor electronic switch module to enable the lifting motor to rise to the upper limit position, and outputs a disinfection control signal to the integrated driver, amplifies the disinfection control signal by the integrated driver, and outputs a disinfection output signal XIAODUO to the disinfection electronic switch module to start a disinfection function.

In the specific embodiment of the invention, when it is judged that no human body approaches the clothes airing machine according to the human body detection signal, a low-level drive chip enable control signal EN is sent to the illumination drive module to control illumination to be turned off, a motor rising control signal M _ UP is output to be a low level/a motor falling control signal M _ DOWN is output to be a high level, the integrated driver amplifies the high level, then a corresponding motor rising signal M _ UP _ ON/the motor falling signal M _ DOWN _ ON is output to the motor electronic switch module to control the rising of the lifting motor, the lifting motor is enabled to run to the upper limit to stop, meanwhile, a low-level disinfection control signal is output to be amplified by the integrated driver, then a corresponding disinfection output signal XIAODUO is output to the disinfection electronic switch module, and the disinfection function.

Preferably, in step S2, the disinfection function is started and timed, and real-time monitoring and determining whether the disinfection start time is greater than the preset time X? If so, a disinfection control signal for closing the disinfection function is sent and amplified by the integrated driver, and then a corresponding disinfection output signal XIAODUO is output to the disinfection electronic switch module to close the disinfection, and if not, the disinfection is continuously opened.

Step S3, when a human body is detected to approach the clothes drying machine, a disinfection control signal is sent to the integrated driver, the integrated driver amplifies the disinfection control signal, the XIAODUO is output to the disinfection electronic switch module to close the disinfection function, when the clothes drying machine is judged not to be at the lower limit or reach the maximum stroke, a corresponding control signal is output to the motor electronic switch module to enable the lifting motor to operate to the lower limit, and the step S4 is entered.

Specifically, in step S4, performing ambient light detection according to the light detection module, obtaining the current ambient light intensity, determining whether the current ambient light intensity is lower than a preset value (e.g., 200Lx), and if not, sending a low-level driver chip enable control signal EN to the lighting driver module to control lighting to be turned off; if so, sending a high-level driving chip enable control signal EN to the illumination driving module to control illumination to be turned on.

Preferably, in step S4, the lighting function is turned on and simultaneously timed, and real-time monitoring and determining whether the lighting on time is greater than the preset time Y? If the lighting control circuit is in the off state, a low-level driving chip enabling control signal EN is sent to the lighting driving module to control lighting to be off, and if the lighting control circuit is not in the on state, lighting is continuously controlled to be on.

If so, outputting a high-level disinfection control signal to close disinfection, otherwise, continuing to open disinfection.

If the MCU controller 50 detects that a human body approaches according to the human body detection module, the disinfection is required to be closed, and a high-level disinfection control signal XIAODU is sent to the disinfection electronic switch module through the integrated driver; and meanwhile, according to the limit detection switch, determine whether the clothes drying machine is currently at the lower limit or whether the clothes drying machine has reached the maximum travel? If so, controlling the lifting motor not to run, otherwise, sending a motor ascending control signal M _ UP to be a high level/a motor descending control signal M _ DOWN to be a low level to the integrated driver for amplification, and then outputting a corresponding control signal to the motor electronic switch module to control the lifting motor to run and descend to a lower limit position and stop, meanwhile, when a human body is detected to approach, carrying out ambient light detection by using the illumination detection module 40, judging whether the current ambient light intensity is lower than 200Lx according to the ambient light intensity detected by the illumination detection module 40 (the sensor module B), and if not, sending a driving chip enabling control signal EN to output the low level to the illumination driving module to control illumination to be turned off; if yes, outputting a high level to the illumination driving module through the driving chip enable control signal EN to control illumination to be turned on, turning on an illumination function, and further continuously judging whether illumination on time is greater than a set value Y? And if so, sending a driving chip enable control signal EN to output a low level to the illumination driving module to control illumination to be turned off, otherwise, continuously turning on the illumination.
