Description
Technical field
The present invention relates to a kind of heat-storage heat-preserving formula electric kettle, this electric kettle can boiling water and water temperature is remained on required preference temperature for a long time.Belong to the daily living article technical field.
Background technology
At present, electric heater is the common tool of people's daily life, and electric heater is because its to boil water fast, smokeless and odorless have the characteristics such as environmental protection, and is welcomed by the people.Particularly people have special requirement to the water quality water temperature when making tea, infuse coffee, brewing milk powder, lotus root starch or bubble kung fu tea.As brew the high-grade tea such as Dragon Well tea, high-quality green tea, normally 80～85 ℃ of boiling water optimums; Make coffee or rush milk powder, lotus root starch etc., normally require the boiling water more than 85 ℃; And when drinking kung fu tea, need water temperature to keep about 95 ℃ in about 20 minutes always, should not repeatedly heat again, boil and change " fresh " of water.But electric heater of the prior art does not have heat insulation function mostly, perhaps, although have certain heat insulation function, has unreasonable structure, the poor shortcoming of heat insulation effect, therefore, can not satisfy the daily life needs.And traditional device that is used for the boiling water insulation, such as thermos flask, it is to rely on the sealing that vacuumizes in the middle of the double-deck glass liner with bottle plug to reduce radiation loss and guarantee insulation effect, but these attemperators do not possess from heating and boiling water function, particularly in both, there is any one impaired its insulation effect just obviously to descend, roll also fast reducing of (opening) coolant-temperature gage, the glass inner flask is easy to again breakage.Therefore, these thermos flasks can not satisfy people's the needs of making tea, infuse coffee, brew milk powder, lotus root starch or bubble kung fu tea equally.Because rhythm of life is nervous, people often forget and oneself heat up water, if water is dryouied, cause easily fire.
Summary of the invention
The objective of the invention is in order to address the above problem, provide a kind of heat accumulation automatic heat-insulation type and with the electric kettle of burning prevention function, water in the kettle through boiled to 100 ℃ boiling water, this electric kettle can remain on required optimal temperature for a long time with water temperature, the boiling water temperature requirement of the high tealeaves such as Longjing tea, tippy tea can be satisfied, the boiling water temperature requirement when making coffee, rushing milk powder, lotus root starch or ordinary tea leaves can be satisfied again.
