Title:
POWER CONTROL UNIT AND ARRANGEMENT OF SUCH A POWER CONTROL UNIT WITH AN ELECTRIC HEATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/189541
Kind Code:
A3
Abstract:
A power control unit for controlling a power output of an electric heating device is in the form of a structural unit and has a power switch and a release mechanism. The release mechanism has a bimetallic release and a heater therefor. The heater has a two-dimensional carrier with an electrically insulating top side, on which a heating conductor is arranged. For a quicker switching behaviour, the carrier may consist of ceramic and have a thickness of less than 1.5 mm, and/or the power control device may have an elongate compensation bimetallic strip, which has a freely movable compensation end. This is pressed against the release mechanism and can compensate for changes in the ambient temperature, which also affect the bimetallic release.
