Description

Technical Field

[0001] The utility model relates to the technical field of electric kettles, in particular to a temperature controller for an electric kettle. Background Art

[0002] Electric kettles are essential electrical appliances in modern kitchens and living rooms because they can boil water quickly and conveniently. At the same time, the thermostat controls whether the current flows through the water temperature. Its working principle is that when the temperature reaches the power-off temperature, the thermistor bimetallic strip deforms and drives the corresponding contacts, thereby achieving the power-off function.

[0003] The current temperature control effect is that the water vapor transmission channel opened on the kettle transports water vapor to the temperature control spring, and the temperature control spring senses the water temperature change. However, since the water vapor is in direct contact with the overall thermostat, the exposed conductive parts will inevitably be corroded by the water vapor after long-term use, affecting the service life of the overall structure. Utility Model Content

[0004] The purpose of the utility model is to solve the current temperature control effect in which the water vapor is transported to the temperature control spring through the water vapor transport channel opened on the kettle, and the temperature control spring senses the water temperature change.
