Description

Electric kettle with water level detection function

Technical Field

The utility model relates to the technical field of hot water kettles, in particular to an electric kettle with water level detection.

Background

The electric kettle has the working principle that steam generated during boiling of water causes the bimetallic strip of the steam temperature sensing element to deform, and the deformation pushes the power switch to cut off power through the lever principle. The kettle can not be reset by itself after the power is cut off, so the kettle can not be automatically reheated after the power is cut off. At present, for a common electric kettle (an electric kettle with an automatic water adding device), dry heating easily occurs under the anhydrous condition, the electric kettle has influence on the service life of a product after long-time dry heating, and meanwhile, the surface of a heating plate changes color and turns yellow to influence the use body feeling of consumers.
