The Banqiu HD-72 type high-temperature disinfection cabinet uses remote infrared high-temperature disinfection. It has many advantages such as fast warming, thorough disinfection, automatical temperature control, safe to use, and so on.1.The principle of the circuit.The principle circuit which is drawn based on the physical circuit is shown in the picture. The whole circuit is made up of two parts which are control circuit (in the border of the picture) and heating and disinfection circuit.When it is connected to the power, by pressing the disinfection button SB1, the 220V AC power would be added on the VD2~VD5 bridge rectifier and C2 filter through the disinfection temperture controller ST, over-temperature fuse FU, diode VD1, current-limiting resistor R1, thermistor RT (PTC). This would make the relay K1 be closed and the normally open contactor K1-1 would also be closed.
