Specific embodiment
As shown in Fig. 1, induction type electric heating windshield control circuit include transparent electric heating film, temperature difference inductor,
Surge absorber, defrosting-defogging relay and temperature display relay, the transparent electric heating film are evenly applied to windscreen surface
Or in interlayer, temperature difference inductor is arranged in windshield surfaces externally and internally in Multipoint Uniform.Transparent electric heating film, temperature difference inductor and wave
Gush absorber and the connection of defrosting-defogging relay.As shown in Fig. 2, when temperature difference inductor detects windshield hull-skin temperature
When lower than internal surface temperature, the conducting of defrosting-defogging relay, transparent electric heating film starts to heat windshield, when the glass that keeps out the wind
Stop heating, surge absorber absorbing circuit generated high impulse electricity when being connected and disconnecting when glass surfaces externally and internally temperature is consistent
Pressure, protects circuit not to be burned out.
Since transparent electric heating film power is larger, the high pulse voltage that circuit is connected and can generate when disconnecting can burn circuit,
The surge that TVS Transient Suppression Diode is generated as the conducting of surge absorber absorbing circuit and when disconnecting is set, protects circuit not
It is burned out.
The temperature difference inductor is transparent enclosure, does not influence sight.
The induction type electric heating windshield control circuit uses vehicle-mounted accessory power supply direct current supply.
The induction type electric heating windshield control circuit setting functional shielding switchs, and can shield manually from dynamic
Function is answered, convenient for energy saving when the power generation of vehicle neutral gear.The functional shielding switch is wireless switching.It is set to steering wheel
On.
The induction type electric heating windshield control circuit can be used for shield glass, rear seat windscreen,
