Description
Technical field
The utility model relates to the vacuum heat insulation type electric kettle with automatic sealing and 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 electric heating appliance technical field that belongs to daily living article.
Background technology
At present, electric heater is the common tool of people's daily life, and electric water 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.
The utility model content
The purpose of this utility model is in order to address the above problem, a kind of vacuum heat insulation type electric kettle with automatic sealing and long-acting thermal-insulating structure is provided, 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.
The purpose of this utility model can reach by following measure:
Vacuum heat insulation type electric kettle with automatic sealing and long-acting thermal-insulating structure comprises kettle body and pot lid, and its design feature is:
1) described kettle body comprises shell and the inner bag that is arranged at enclosure, bottom at the kettle body is provided with electric heater, the heater of electric heater and inner bag close contact, between shell and inner bag, be provided with closed cavity, described closed cavity is evacuated, and forms the sealed vacuum thermal insulation layer between shell and inner bag; Consist of 80 ℃～95 ℃ vacuum type insulation constructions by inner bag and sealed vacuum thermal insulation layer;
2) electric heater comprises heater and thermal store, the heater of electric heater and inner bag close contact, thermal store be looped around heater around, thermal store is connected, forms the dispersion shape syndeton by some connectors with heater, 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;
3) described pot lid is provided with the gas outlet, and the place is provided with piston structure in the gas outlet, the open and close of described piston structure control gas outlet.
4) 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, the temperature remains within the normal range to make shell simultaneously.
The beneficial effects of the utility model are:
1, the utility model is owing to be provided with sealed vacuum heat-insulation layer, 80 ℃～95 ℃ airtight vacuum formula insulation constructions of formation, 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 ℃, water temperature remains on required optimal temperature (being phase transformation temperature points) always, the heating boiling water that needn't consume energy again, 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 utility model, form heat insulation cavity between described sealed vacuum thermal insulation layer outer wall 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 utility model, described pot lid is provided with the gas outlet, the place is provided with piston structure in the gas outlet, the open and close of described piston structure control gas outlet.When hot water was boiled, the steam jack-up in the kettle was located at the piston structure at place, gas outlet, and piston is moved up, and at this moment, open the gas outlet, and communicate with outside air, and steam is just discharged by the gas outlet; When steam in the kettle weakens can not support piston structure the time, piston structure naturally puts down and blocks the gas outlet, thereby closes the gas outlet, and this structure has avoided the discharge of a large amount of steam to take away heat, but also can utilize steam to keep water temperature.
4, the employed sealed vacuum heat-insulation layer of the utility model and temperature control circuit structure, can design the energy-saving type heat-preserving insulating pot of Multiple Type, the user can select according to actual needs, water temperature can be remained on always 95 ℃ of temperature of required optimum as during drinking kung fu tea, rolling (opening) kettle, the again heating water that needn't consume energy, 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; When brewing Longjing tea, can regulate temperature control circuit, make electric kettle consist of the energy-saving type heat-preserving electric kettle of 85 ℃ of series; When brewing tippy tea, the temperature control that can regulate temperature control circuit is that 80 ℃, 82 ℃ or 84 ℃ are the most desirable; Rush coffee bubble coffee, when rushing milk powder or lotus root starch, the temperature control that can regulate temperature control circuit is 86～95 ℃.
