The dry-burning-resisting temperature controller guarantees safety of the electric kettle in daily life, and fire hazards are avoided.
Description
Technical field
The utility model relates to a kind of domestic electric heating kettle.
Background technology
It is the most frequently used one of instrument of heating up water in people's daily life that electric kettle has become, and it has quick, smokeless and odorless to boil water, the advantage of hygienic environment-protecting.But electric kettle of the prior art does not have the unreasonable structure of heat insulation function or heat insulation function, heat insulation effect poor mostly; Perhaps adopting the mode of insulation then is that electric kettle is placed on the power supply chassis always, realizes heat insulation function by lasting or interruptedly supplying power, very inconvenient.Therefore when people have special requirement to water temperature, such as brewing the high-grade tea such as Dragon Well tea, high-quality green tea, 80～85 ℃ of boiling water optimums normally, make coffee or rush milk powder, lotus root starch etc., normally require the boiling water more than 85 ℃, need water temperature to keep in 20 minutes about 95 ℃ and drink kung fu tea, heat insulation effect is bad even do not have the electric kettle of heat insulation function just can not satisfy the demand always.Because rhythm of life is nervous, people often forget and oneself heat up water, if water is dryouied, cause easily fire.
The utility model content
The purpose of this utility model provides a kind of that can be incubated and with the electric kettle of burning prevention function.
The utility model is by the following technical solutions:
The vacuum heat accumulation Double insulating formula anti-dry electric kettle of a kind of top water outlet comprises kettle body 1, pot lid 2, and kettle body bottom is provided with electric heater unit 3, and kettle body 1 is connected with pot lid 2 by screw thread; Be provided with delivery port 21 at described pot lid top, water outlet is provided with capping 22; Described kettle body 1 is by shell 11 and place the inner bag 12 in the shell to form, between described shell and inner bag, fill phase-change heat-storage material and form reservoir 13, the phase transition temperature of described phase-change heat-storage material is 80,85,90,95 ℃, and reservoir 13 is adjacent to inner bag 12; Be provided with vacuum layer 15 between described reservoir and shell, described vacuum layer is the closed cavity that is evacuated; Filled and process insulation material between described vacuum layer and shell forms heat-insulation layer 14; Described electric heater unit 3 comprises heater 31 and anti-dry heating temperature controller 30, and described anti-dry heating temperature controller is closed type and is connected in the loop of described heater that described heater directly contacts with inner bag 12.
Described kettle body 1 is provided with sealing ring 24 with the junction of pot lid 2.
The utlity model has following advantage:
1. the utility model adopts the reservoir of phase-change heat-storage material, and is different by the phase transition temperature of phase-change heat-storage material, can make the constant temperature kettle of various different temperatures;
2. by using reservoir parcel inner bag, vacuum layer parcel reservoir is realized the Double insulating effect, make reservoir can heat loss and the insulation material of reservoir can be by filling as much as possible, so temperature retention time is longer, better effects if;
3. heat-insulation layer and vacuum layer guarantee that the external table temperature of kettle is normal temperature, and convenient the use can not scalded the user;
4. guarantee the security of electric kettle in routine use by anti-dry heating temperature controller, avoided fire;
5. the kettle top sets out the mouth of a river, has save Hu Zui, makes kettle structure simple, is easy to processing.

The specific embodiment
As shown in Figure 1, the vacuum heat accumulation Double insulating formula anti-dry electric kettle of a kind of top water outlet comprises kettle body 1, pot lid 2, and kettle body 1 is connected with pot lid 2 by screw thread, is provided with internal thread at inner bag 12 opening parts of kettle body 1, is provided with external screw thread in the lower end of pot lid 2; Be provided with delivery port 21 at described pot lid top, water outlet is provided with capping 22.Handle 25 is set on the kettle body, and handle is positioned at the offside of delivery port 21.Between described kettle body 1 and the pot lid 2 sealing ring 24 is set.By setting out the mouth of a river at the kettle top, make kettle structure simple, be easy to processing; Be provided with capping 22 at water outlet 21, much cleaner, heat insulation effect is also better.
Such as Fig. 1, described kettle body 1 is by shell 11 and place the inner bag 12 in the shell to form, fill phase-change heat-storage material and form reservoir 13 between described shell and inner bag, the phase transition temperature of described phase-change heat-storage material is 80,85,90,95 ℃, and reservoir 13 is adjacent to inner bag 12.Namely be lower than the phase transition temperature of phase-change heat-storage material when the water-in-kettle temperature, phase-change heat-storage material phase transformation heating, reservoir 13 heating inner liners heat up water.According to applicable situation with use coolant-temperature gage, select suitable phase-change heat-storage material, make the electric kettle of different thermostat temperatures.For example, kung fu tea need to be near boiled water temperature, and therefore using phase transition temperature is 95 ℃ phase-change heat-storage material, guarantees that the water temperature in the electric kettle is constant in 95 ℃; When brewing Longjing tea, select used 85 ℃ of phase transition temperature materials electric kettle; When brewing tippy tea, can select 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.Be provided with vacuum layer 15 between described reservoir and shell, described vacuum layer is the closed cavity that is evacuated.Vacuum layer can play good adiabatic heat-insulation effect.Adopted the heat storage type heat preserving mode of phase-change heat-storage material as reservoir, add the Double insulating mode of vacuum heat-preserving, guaranteed that water temperature is constant on the one hand, liberated on the other hand the position of electric kettle, can electric kettle be placed on the power supply chassis always.
Such as Fig. 1, between described reservoir and shell, be provided with the heat-insulation layer 14 of being made by cellular insulant, prevent 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.
Kettle body bottom is provided with electric heater unit 3, described electric heater unit 3 comprises heater 31 and anti-dry heating temperature controller 30, such as Fig. 2, 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.
