Detailed Description
A novel shoe dryer is characterized in that a humidity-sensitive control circuit, a fan and an ultraviolet module are respectively arranged on two heating sheets of a common shoe dryer.
After passing through the rectifying module, the 220V/50Hz alternating current is charged to C1 through RH. When the capacitor charge reaches a certain value, the discharge is started and the D1 light-emitting diode indicator lamp is lighted. The first base electrode of the Q1 is conducted by the Q1, current flows through the first base electrode to generate voltage, the controlled silicon U1 is conducted, the heating resistor RL is electrified to generate heat and enters a temperature rising state, the ultraviolet module starts to work after being electrified, and the sterilization effect is achieved.
The inverting input end of the U2 is connected with the potentiometer, an initial threshold voltage is generated, when the voltage of the positive electrode of the capacitor C1 is lower than that of the inverting input end, the output end of the U2 is connected to the relay in a low level mode, and the relay cannot be attracted. When the resistance value along with the RH point changes along with the humidity, the voltage of the positive electrode of the C1 is higher than the threshold voltage, and the output end of the U2 outputs low level, so that the relay is attracted, and the motor starts to work. Along with the change of the resistance value of the humidity RH, the voltage of the positive electrode of the C1 is lower than the threshold voltage again, the output end of the U2 is at a low level, and the relay disconnects the motor to stop working.
The RH resistance begins to change, the time constant of the charging loop increases, the conduction angle of U1 decreases, and thus the heating power of RL decreases, and the uv intensity of the uv module decreases. When the humidity in the shoe is reduced to the set value, the conduction angle of the U1 is approximately zero, and the shoe dryer is not working. Otherwise, when the U1 is triggered to be conducted again, the RL and ultraviolet modules start to work again.
The R1 and R5 function as protection resistors to prevent the RH and potentiometer R6 resistance values from dropping too low, thereby shorting out the circuit.
