Description
Technical field
The present invention relates to a kind of vacuum, heat-storage heat-preserving formula anti-dry electric kettle with long-acting thermal-insulating structure, and this electric kettle can boiling water and water temperature remained on required preference temperature for a long time.The technical field that belongs to the daily living article electric heating appliance.
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, approximately need water temperature to keep about 95 ℃ in 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, easily cause fire.
Summary of the invention
The objective of the invention is in order to address the above problem, provide a kind of vacuum with long-acting automatic heat preserving structure, heat-storage heat-preserving formula 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.
Purpose of the present invention can reach by following measure:
Have the vacuum heat accumulation heat preserving type anti-dry electric kettle of long-acting automatic heat preserving structure, comprise kettle body and pot lid,
Described kettle body comprises shell and is arranged at the inner bag of enclosure, bottom at the kettle body is provided with electric heater, described electric heater 3 comprises heater 3-1, thermal store 3-2 and anti-dry heating temperature controller 3-5, described anti-dry heating temperature controller is closed type and is connected in the loop of described heater, described heater directly contacts with inner bag 12, thermal store be looped around heater around, thermal store is connected with heater by some connectors, form the dispersion shape syndeton, in section connecting element, be provided with heat conduction tie point, closely be connected with inner bag by described heat conduction tie point, make thermal store and inner bag form the point-like syndeton; Between shell and inner bag, be provided with closed cavity, in described closed cavity, fill up phase change heat-storing material, form closed phase change heat storage layer; The phase transformation fusing point of described closed phase change heat storage layer is 80～95 ℃; Between shell and closed phase change heat storage layer, be provided with the vacuum tightness cavity and consist of the sealed vacuum thermal insulation layer.
Thermal store is connected, forms the dispersion shape syndeton by six connectors with heater, respectively be provided with a heat conduction tie point in three connectors therein, closely be connected with inner bag by described heat conduction tie point, make thermal store and inner bag form the point-like syndeton.
