Description

technical field

[0001] The invention relates to a thermosensitive temperature control device, in particular to a thermosensitive temperature control device applied to a 360-degree rotary liquid heater, and also to a liquid heater using the solution. Background technique

[0002] Liquid heaters, especially liquid heaters such as electric kettles generally need a heat-sensitive temperature control device to control the power-off protection of the liquid heater under abnormal heating conditions. Usually this heat-sensitive temperature control device is installed together with the electric heater in order to get better thermal contact. In the already known patents DE2556062.7 and DE2648488.8, a heat-sensitive responsive bimetallic actuator and its application to a temperature control device are disclosed. These two patents are widely used in mechanical thermosensitive temperature control devices as commonly used thermosensitive sensing schemes.
