Title: Heating control for hair treatment equipment - has temp. sensitive element which bends or releases spring operating switch
Inventor: KERBER KARL
IPC: A45D1/28
Filed: 1977-07-27
Abstract: The equipment has an electric heater and near it a sensor tube with a high coefficient of thermal expansion. Inside the tube is a rod with low coefficient of expansion, coupled to the tube in at least one point, while the tube is clamped at another point, so that the rod moves in the tube when the temp. changes. This movement is transmitted to a switch through an adjustable mechanism. The switch breaks or closes the heat circuit. The rod (22) with low coefficient of expansion acts on the free end of a spring (23) fastened to the equipment case, and reduces pressures on it when the temp. rises. When the temp. falls, the spring (23) bends more and moves a switch (31) operating element (20).
