Holding temperature range adjustable electric kettle

Abstract

The invention provides a holding temperature range adjustable electric kettle comprising a kettle body provided with an electric heating plate. The kettle body is provided with two power terminals connected with the mains supply, the electric heating plate is provided with a first terminal and a second terminal, the first terminal is connected with the first power terminal, and the second terminal is connected with the second power terminal through a temperature control unit; the temperature control unit comprises a steam temperature control switch and a normally-open adjustable temperature controller; the steam temperature control switch comprises a body and a tappet, the body is provided with an input terminal, an output terminal and a heat preservation terminal, both the heat preservation terminal and the input terminal are fixed by the side of the tappet, an annular conducting strip is fixed on the tappet, and after the conducting strip is bounced by the body, the annular conducting strip can connect the heat preservation terminal with the input terminal; one end of the adjustable temperature controller is connected with the second terminal while the other end is connected with the heat preservation terminal of the steam temperature control switch; the output terminal of the steam temperature control switch is connected with the second terminal, and the input terminal of the same 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 kettle with an adjustable heat preservation range. 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 h...

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.
