Overheat protection control component for a liquid heating vessel

摘要

The invention provides an overheat protection control component for a liquid heating vessel which includes a control body(1); a single-integrated dual-actuation thermally sensitive bimetallic actuator(2) is provided on the upper face of the control body(1), wherein the single-integrated dual-actuation thermally sensitive bimetallic actuator(2) is two integrated and relatively independent actuating units which are formed on a piece of bimetallic strip, and the outer kick limb(3) of either said actuating unit will produce an actuating movement downwards when an overheat state occurs; two groups of switch contacts(6) are also provided on the control body(1), wherein either group of switch contacts(6) cooperate with the outer kick limb(3) of a corresponding actuating unit, and the outer kick limb(3), when producing a downward actuating movement, will open a corresponding group of switch contacts(6) and cut off the power supply of the heater for the liquid heating vessel.
