Electric kettle with thermal insulation function

Abstract

The invention provides an electric kettle with a thermal insulation function. The electric kettle comprises a kettle body with an electric heating disc; the kettle body is provided with two power terminals to be connected with the mains supply; the electric heating disc comprises a first terminal and a second terminal; the first terminal is connected with the first power terminal; the second terminal is connected with the second power terminal through a temperature control unit; the temperature control unit comprises a thermostatic kick switch and a thermostatic steam switch; the thermostatic steam switch comprises a body and a tappet, the body is provided with an input terminal, an output terminal and an insulation terminal, both the insulation terminal and the input terminal are fixed beside the tappet, a circular conductive sheet is fixed to the tappet, and after the tappet is popped up by the body, the circular conductive sheet connects the insulation terminal and the input terminal; one end of the thermostatic kick switch is connected with the second terminal, and the other end is connected with the insulation terminal of the thermostatic steam switch; the output terminal of the thermostatic steam switch is connected with the second terminal, and the input terminal thereof is connected with the second power terminal.

Description

technical field [0001] The invention belongs to the technical field of household appliances, and in particular relates to an electric heating kettle with heat preservation function. Background technique [0002] The electric heating kettle with a built-in electric heating plate can automatically cut off the power after the water is boiled. It has the advantages of fast heating speed, convenient operation, and safety. It has been welcomed by consumers and has gradually become popular. However, this kind of electric heating kettle generally only has a single function of boiling water, and does not have a heat preservation function. If the water is not quickly poured into the thermal insulation kettle after the water is boiled, then the water in the electric heating kettle will cool down. The cooling speed is very fast, and people often need to press the switch again to reheat the boiled water, and the convenience of use is compromised. [0003] In addition, some electric hea...

Problems solved by technology

However, this kind of electric heating kettle generally only has a single function of boiling water, and does not have a heat preservation function. If the water is not quickly poured into the insulation kettle after the water is boiled, then the water in the electric heating kettle will cool down, and the hot water will be hot in winter. The cooling speed is very fast, people often need to press the switch again to reheat the boiled water, and the convenience of use is compromised

[0003] In addition, there are also some electric heating kettles with heat preservation function, but they can only keep the water at a temperature above 95°C. Because the temperature is too high, they cannot be drunk directly, and keeping the water at a high temperature will waste a lot of electric energy.
