AN OVERHEAT PROTECTION CONTROL UNIT FOR LIQUID HEATER

摘要

The present invention provides an overheat protection controller assembly of a liquid heating vessel, which comprises a control body, a monolithic conjoined double-actuating thermal sensitive bimetal actuator arranged on the upper surface of the control body, and two groups of switch contacts arranged on the control body correspondingly, each group of the switch contacts cooperating with a corresponding actuating unit. The monolithic conjoined double-actuating thermal sensitive bimetal actuator is comprised of two conjoined actuating units which are relatively independent and formed of a bimetal sheet. An edge line of each of the two actuating units is partially located at the inner side of an edge line of the other. The monolithic conjoined double-actuating thermal sensitive bimetal actuator has a common join part which is located at the inner side of each said actuating unit's edge line and effectively makes two actuating units form the monolithic conjoined double-actuating thermal sensitive bimetal actuator.
