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 provides a kind of heat-storage heat-preserving type thermostatic control electric kettle with steam outlet, to solve long-acting thermal-insulating, the convenience of use and the technical problems such as extensive adaptability of use of electric kettle.
In order to realize the foregoing invention purpose, the technical scheme that the utility model adopts is as follows:
Heat-storage heat-preserving type thermostatic control electric kettle with steam outlet, comprise kettle body and pot lid, be provided with up big and down small variable-diameter structure gas outlet at pot lid, be provided with piston structure up big and down small and that be slidingly matched with it in the gas outlet, this piston structure is the discharge of steam switch of gas outlet; Described kettle body comprises shell and is arranged at the inner bag of enclosure, bottom at the kettle body is provided with electric heater, the heater of electric heater comprises heating element to boil water and insulation electric boiling plate heating element, and described heating element to boil water and insulation electric boiling plate heating element are attempted by both ends of power respectively with after separately temperature controller is connected in series; Described heater and inner bag close contact fill up the closed cavity of phase change heat-storing material in being provided with between shell and inner bag, to form closed phase change heat storage layer; The phase transformation fusing point of described closed phase change heat storage layer is 80～95 ℃; Have a thermal store be looped around heater around.
Described heat-storage heat-preserving type thermostatic control electric kettle with steam outlet, 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;
Described heat-storage heat-preserving type thermostatic control electric kettle with steam outlet arranges heat insulation cavity between the outer wall of phase change heat storage layer and outer casing inner wall, establish foam layer in this heat insulation cavity.
Described heat-storage heat-preserving type thermostatic control electric kettle with steam outlet, described pot lid is provided with the delivery port that is communicated with the inner chamber of inner bag, is provided with capping at water outlet, and 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.
The beneficial effects of the utility model are:
1, the utility model is owing to be provided with closed phase change heat storage layer, 80 ℃～95 ℃ heat storage type insulation constructions of formation, therefore with boiled after 100 ℃, water temperature can remain on required optimal temperature (being phase transformation temperature points) for a long time, needn't cross power consumption heating boiling water repeatedly, 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.
2, owing in the improvement technical scheme of the present utility model, form heat insulation cavity between described phase change heat storage layer outer wall and the shell, in heat insulation cavity, establish foam layer.Thereby greatly reduce the heat loss of phase change heat storage 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 phase transformation fusing point of the employed phase change heat-storing material of the utility model is 80 ℃～95 ℃, can design the energy-saving type heat-preserving electric kettle of Multiple Type, the user can select according to actual needs, as when brewing Longjing tea, selects the electric kettle of 95 ℃ of series; When brewing tippy tea, can select 80 ℃, 82 ℃, 83 ℃, 85 ℃, 86 ℃, 88 ℃, 90 ℃, 92 ℃, 94 ℃ or 95 ℃ of any one electric kettles; Rush coffee bubble coffee, when rushing milk powder or lotus root starch, can select as required 80～95 ℃ of electric kettles that wait series.
