Abstract
To be able to determine an ice or snow formation reliably, a cold conductor connected to an electrical power source is provided, with which the heat abstraction intensely occurring due to ice or snow is measured and used as a signal for ice or snow formation. The intensified heat abstraction on the cold conductor is determined by a current meter for determining an increased power consumption or by a thermistor which is in heat-conductive connection with the cold conductor and switches the power supply of the cold conductor on and off as a function of the temperature.
