Liquid heating ware overheating protection controller assembly

Abstract

The invention provides a liquid heating ware overheating protection controller assembly, which comprises a controller body, wherein the upper surface of the controller body is provided with a monolithic connected double braking thermosensitive bimetal actuator; the monolithic connected double braking thermosensitive bimetal actuator is to form two brake units of relatively independent parallel connection bodies on a bimetal sheet; the edge line of each brake unit in the two brake units partially falls into the inner side of the edge line of the other brake unit; the monolithic connected double braking thermosensitive bimetal actuator is provided with a public connection part; the public connection part is positioned on the inner side of the edge line of each brake unit and effectively ensures that two brake units form the monolithic connected double braking thermosensitive bimetal actuator; and the corresponding controller body is provided with two sets of switch contacts and each set of switch contacts are matched with the corresponding brake unit.

Description

technical field [0001] The invention relates to an overheat protection control device, in particular to a liquid heating vessel overheat protection controller assembly. 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 temperature of ...

[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 temperature of the two actuators will also have a certain difference. The actuator with a high actuation temperature The actuator is easy to actuate when the temperature of the heating vessel is too high, resulting in overheating and damage to the heating vessel, while the actuator with low actuation temperature is easy to actuate when the temperature of the heating vessel is not too high, causing the heater to work normally. use affected
