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 ...

Embodiment Construction

[0013] Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:

[0014] Among them: 1. Controller body; 2. Single-chip dual-actuation thermal bimetallic actuator; 3. Outer sudden jump wing; 4. Inner tongue; 5. Tongue root; 6. Switch contact; 7. Push rod ; 8, fixed plate; 9, inner tongue jack; 10, rivet; 11, edge line of the actuating unit; 12, edge line of partial common connection; 13, installation hole.

[0015] Such as figure 1 , figure 2 As shown, the liquid heating vessel overheating protection controller assembly includes a controller body 1; the upper surface of the controller body 1 is provided with a monolithic dual-actuation thermal bimetal actuator 2, and the monolithic dual-actuation The dynamic heat-sensitive bimetallic actuator 2 is formed on a piece of bimetallic sheet to form two conjoined and relatively independent actuating units. The outer jumping wing 3 and the tongue root 5 of the inner tongue...
