Abstract

The invention provides an overheat protection controller component used in a liquid heating vessel. The overheat protection controller component comprises a controller body, the upper surface of which is equipped with a monolithic conjunct double-actuation thermosensitive double-metal actuator that is provided with two conjunct and relatively independent actuating units on a piece of double-metal plate. An internal tongue of each actuating unit can actuate downwards under the overheat condition. The controller body is also provided with two sets of switch connection points. Each set of switch connection points are matched with one internal tongue of the corresponding actuating unit. When the internal tongue actuates downwards, the internal tongue can open one corresponding set of switch connection points and switch off the power supply of the liquid heating vessel that is a heater. The overheat protection controller component used in the liquid heating vessel has the characteristics of reliable overheat protection as well as exact and constant actuation.

Description

technical field [0001] The invention relates to an overheat protection control device, in particular to an overheat protection controller assembly for a liquid heating vessel. Background technique [0002] The existing liquid heating vessel overheating protection control device, also known as the anti-dry control device, is mainly used and installed under the bottom of the liquid heating vessel, especially the boiling water vessel, and an electric heating element is installed on the bottom of the vessel. The overheating protection control device mainly includes: Two types, one of which is only equipped with a thermal bimetallic actuator, this type of control device is easy to cause dry heating and overheating and burn out the heating vessel if there is only one actuator failure or failure; the other type is equipped with two A heat-sensitive bimetallic actuator. Due to the difference in material between the two actuators in this type of control device, the actuation temperat...
