Description
Technical field
The present invention relates to a kind of vacuum heat insulation type anti-dry electric kettle of long-acting thermal-insulating structure, belong to the electric heating appliance technical field of daily living article.
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 long-acting automatic heat preserving structure vacuum 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.
Purpose of the present invention can reach by following measure:
A kind of vacuum heat insulation 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; Be provided with closed cavity between shell and inner bag, described closed cavity is evacuated, and forms the sealed vacuum thermal insulation layer between shell and inner bag; Consist of the vacuum type insulation construction by inner bag and sealed vacuum thermal insulation layer;
Described lid is the pot lid of electric kettle, is provided with the water filling port that is communicated with the inner chamber of inner bag at pot lid; The sidewall that is positioned at the water filling port left side on the pot lid stretches out, forms Hu Zui; The roof that is positioned at the water filling port right side at pot lid is provided with the hasp plug; Described hasp plug hasp is covered water filling port on Hu Zui fully.
Between the outer wall of sealed vacuum thermal insulation layer and outer casing inner wall, heat insulation cavity is set, in this heat insulation cavity, establishes foam 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.
The kettle body is connected with pot lid by screw thread; Inner bag opening part at the kettle body is provided with internal thread, is provided with external screw thread in the lower end of pot lid; On pot lid, also be provided with the O RunddichtringO.
Described kettle body be shaped as truncated cone, square, polygonal cylindricality or cydariform.
Sidewall at described shell is provided with handle.
The invention has the beneficial effects as follows:
1, the present invention consists of airtight vacuum formula insulation construction owing to be provided with the sealed vacuum heat-insulation layer, therefore with boiled after 100 ℃, water temperature remains on required optimal temperature (temperature control temperature spot) always, needn't repeat power consumption heating boiling water, not only energy-conservation but also can avoid with the water heating for multiple times of making tea contribute trace element useful in the dehydration, " fresh " of the water that keeps making tea.Simultaneously, because the characteristic of thermal store self-heat conserving, the heat energy of thermal store storage can only conduct tie point by heat and heat to inner bag, therefore, thermal store to inner bag and the boiling water heating be slow and lasting, have the beneficial effect of long-acting thermal-insulating.Therefore with boiled after 100 ℃, the water temperature long period remains on required optimal temperature (being phase transformation temperature points), needn't be after many power consumptions heating boiling water, not only energy-conservation but also can avoid with the water heating for multiple times of making tea contribute trace element useful in the dehydration, " fresh " of the water that keeps making tea.
2, owing in the improvement technical scheme of the present invention, form heat insulation cavity between described sealed vacuum thermal insulation layer and the shell, in heat insulation cavity, establish foam layer.Thereby greatly reduce the heat loss of sealed vacuum thermal insulation layer, strengthen the heat insulation effect of kettle body when the temperature remains within the normal range at shell.
3, because in the improvement technical scheme of the present invention, described pot lid is provided with the water filling port that is communicated with the inner chamber of inner bag; The sidewall that is positioned at the water filling port left side on the pot lid stretches out, forms Hu Zui, and corresponding with it, the roof that is positioned at the water filling port right side on the pot lid is provided with the hasp plug; Described hasp plug hasp is covered water filling port on Hu Zui fully.Not only much cleaner, heat insulation effect is also better.
4, the anti-dry heating temperature controller because the present invention has connected in the loop of heater after water dryouies, is realized auto-cutout by anti-dry heating temperature controller, has guaranteed the security of electric kettle in routine use, avoids fire.
