Title:
ELECTRIC HEATERS
Document Type and Number:
WIPO Patent Application WO1999048333
Kind Code:
A3
Abstract:
An integrated heater and control assembly comprises an electric heater (200) having a resistive heating track (202) provided on an insulating substrate and a thermally sensitive control for the heater built onto the heater. In particular, supports (212a, 212b) for trip levers (230a, 230b) are bonded to the substrate. Trip lever (212b) is operated both by a boiling sensitive actuator (234) and an overheat protection actuator (268) while trip lever (212a) is acted on by the actuator (268) alone. Both trip levers (230a, 230b) are also acted on by bobweights (250a, 250b) which are responsive to movement of the vessel to switch the heater on. Power connection terminals (220, 222, 224) and a mounting flange (300) are also mounted directly onto the heater.
