用ウインドシールドの解氷装置。 In a vehicle windshield de-icing device that generates heat by passing an ice-melting current between electrodes built into the windshield, a fog sensor that detects icing on the windshield is connected in series with the fog sensor. A controller that is connected to the controller and generates a rectangular wave at a constant cycle, a chopper that controls the ice-melting current driven by the output of this controller, a monitoring circuit that monitors the output state of this chopper, and this monitoring circuit. and a circuit breaker driven by the output of the chipper, and configured to drive the circuit breaker with the output of the monitoring circuit to interrupt the deicing current if the output wave of the chopper continues after a predetermined period of time has elapsed. A deicing device for a vehicle windshield, which is characterized by:
