The temperature sensor detects the temperature of the hot air flowing out of the air outlet pipe constantly, and when the temperature of the hot air is larger than a rated temperature value set in the controller, the controller controls the power of the heating pipe to reduce the power of the heating pipe; when the temperature of the hot air is lower than the set rated temperature value, the power of the heating pipe is increased.
When the wet towel is dried, all the elastic films cover the wet towel to be in a horizontal state, hot air in the fixing cover cannot flow out, so that the air pressure at the air outlet pipe of the flow distribution box is increased, and when the air pressure value is larger than the maximum air pressure value set in the controller, the controller controls the fan and the heating pipe to stop working.
The maximum air pressure value is the air pressure value when the wet towels on each drying assembly are dried, air cannot flow out of any one fixed cover, and the air is accumulated at the air outlet pipe of the flow dividing box for 1-2 s.
The air generated by the fan is heated by the heater and enters the diversion box, and enters the fixed cover through the corresponding air outlet of the diversion box; and flows out from the air outlet to dry the wet towel.
Meanwhile, hot air pushes each elastic membrane to rotate the hook, and the ultraviolet lamp can uniformly irradiate on the wet towel to sterilize the wet towel.
A user hangs the wet towel on the hook, and the controller automatically controls the fan, the heater and the ultraviolet lamp to work; and after the wet towel is dried, the controller controls the fan, the heater and the ultraviolet lamp to stop working.
