The specific embodiment

As shown in Figure 1, a kind of long-acting thermal-insulating formula anti-dry electric kettle comprises kettle body 1, pot lid 2, between described kettle body 1 and the pot lid 2 sealing ring 24 is set.Handle 25 is set on the kettle body, and the offside of handle sets out the mouth of a river 16 and kettle mouth 17, and kettle mouth 17 ends are provided with spout lid 18.

Such as Fig. 1; described kettle body 1 is comprised of shell 11 and inner bag 12, and the filled and process insulation material forms the heat-insulation layer 14 of being made by cellular insulant between described inner bag and shell, prevents that reservoir from dispelling the heat to kettle outward; guaranteed that simultaneously the kettle body case is normal temperature, the protection user can not be burned.Described delivery port 16 is positioned at kettle body 1 middle part and is communicated to inner bag 12.

Kettle body bottom is provided with electric heater unit 3, and described electric heater unit 3 comprises heater 31, thermal store 32 and anti-dry heating temperature controller 30, and described heater directly contacts with inner bag 12.

Such as Fig. 2, described heater around around thermal store 32, described thermal store 32 is connected with heater 31 by six connectors 33 and forms the dispersion shape syndeton, in three connectors 33, respectively be provided with heat conduction tie point 34, described thermal store 32 closely is connected with inner bag 12 by described heat conduction tie point, makes thermal store and inner bag form the point-like syndeton.Heater 31 also heats thermal store 32 in to inner bag 12 heating, when the water boiling in being heated to inner bag is 100 ℃ of water temperatures, and heater 31 stopped heatings, this moment, thermal store also was warming up to 100 ℃.Because inner bag and boiling water drop in temperature wherein are very fast, thermal store continues inner bag is heated by heat conduction tie point 34.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 the phase transformation temperature points that required optimal temperature is thermal store always.

Difference according to required water temperature, select the thermal store of different phase transformation temperature pointses to make the long-acting thermal-insulating formula electric kettle of different functions, for example, kung fu tea need to be near boiled water temperature, then use phase transition temperature to make heat-insulation layer as 95-100 ℃ phase-change heat-storage material, guarantee that the water temperature in the electric kettle is constant in 95-100 ℃; When brewing Longjing tea, select used 85 ℃ of left and right sides phase transition temperature materials electric kettle; When brewing tippy tea, can select 80 ℃～85 ℃ of phase transition temperature materials electric kettle; Make coffee or rush milk powder, lotus root starch etc., usually select 85～95 ℃ of phase transition temperature materials electric kettle.Adopt thermal store to realize long-acting thermal-insulating, liberated simultaneously the position of electric kettle, needn't electric kettle be placed on the power supply chassis always.

Such as Fig. 3, described anti-dry heating temperature controller is closed type and is connected in the loop of described heater that described heater 31 directly contacts with inner bag 12.If the boiling water cut-off switch of electric kettle damages, water-in-kettle can dryout always, and this moment, the closed type anti-dry heating temperature controller can be because crossing thermal cutoff, and with the loop open circuit of heater, stopped heating is avoided dry combustion method initiation fire accident.

By setting out the mouth of a river and corresponding long Hu Zui at kettle body middle part, relatively laborsaving during pouring, make tea at a distance when being convenient to make tea, avoid the hot gas of boiling water to cover people's sight line, thereby prevent that the water in the teacup from overflowing, be provided with capping at long Hu Zui, much cleaner, heat insulation effect is also better.
