Abstract
The utility model discloses a vacuum heat preservation type anti-dry burning electric kettle with an air outlet. An electric heater unit is arranged at the bottom of a kettle body. The kettle body is connected with a kettle cover through threads. A sealing ring is arranged at the connecting portion of the kettle body and the kettle cover. A water outlet and the air outlet are formed in the top of the kettle cover. A sealing cover is arranged on the water outlet. A piston is arranged in the air outlet. The kettle body is composed of an outer shell and a liner which is arranged in the outer shell. A vacuum layer is arranged between the outer shell and the liner. The vacuum layer is a closed cavity which is vacuum. The electric heater unit comprises a heater and an anti-dry burning temperature controller. The anti-dry burning temperature controller is normally closed and connected with a return circuit of the heater in series. The heater directly contacts with the liner. By adopting the vacuum layer, the vacuum heat preservation type anti-dry burning electric kettle with the air outlet has the advantages of being capable of not only preserving heat for hot water in a kettle, but also guaranteeing the outer surface temperature of the kettle body to be the normal temperature, convenient to use, not prone to scalding a user. The safety of an electric kettle in everyday use is guaranteed through the anti-dry burning temperature controller. The fire is avoided. The air outlet matches with the piston to achieve automatic exhausting and closing.
Description
Technical field

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:
A kind of vacuum heat insulation type anti-dry electric kettle with the gas 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, and the junction is provided with sealing ring 24; Be provided with delivery port 21 at described pot lid top, water outlet is provided with capping 22; Described pot lid 2 is provided with a gas outlet 23, and described gas outlet is vertical through hole, is provided with a length greater than the piston 26 of gas outlet in gas outlet 23, and described piston lower end is less than the gas outlet, and the piston upper end is greater than the gas outlet; Described kettle body 1 comprises shell 11 and places the interior inner bag 12 of shell that be provided with vacuum layer 15 between shell 11 and inner bag 12, described vacuum layer is the closed cavity that is evacuated; 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.
Filled and process insulation material between described vacuum layer 15 and shell 11 forms heat-insulation layer 14.
At the kettle body 1 interior temperature control circuit that arranges, the water temperature in the kettle body inner bag 12 is controlled at 80 ℃, 82 ℃, 83 ℃, 85 ℃, 86 ℃, 88 ℃, 90 ℃, 92 ℃ or 95 ℃.
Described gas outlet 23 is counterbore.
The utility model has the advantages that:
1. by adopting vacuum layer, can either give hot water thermal insulating in the kettle, can guarantee that again the external table temperature of kettle is normal temperature, the convenient use can not scalded the user.
2. guarantee the security of electric kettle in routine use by anti-dry heating temperature controller, avoided fire.
3. the kettle top sets out the mouth of a river, has save Hu Zui, makes kettle structure simple, is easy to processing.
4. by temperature control circuit is set, constant water temperature, easy to use.
5. be provided with at the kettle top and push piston by steam and realize automatic open and close gas outlet, open when heating up water and be used for row's steam, close for insulation after heating up water.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is heater of the present utility model and anti-dry heating temperature controller wiring diagram;
The specific embodiment
As shown in Figure 1, a kind of vacuum heat insulation type anti-dry electric kettle with the gas 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.
Described pot lid 2 is provided with a gas outlet 23, and described gas outlet is vertical through hole, is provided with a length greater than the piston 26 of gas outlet in gas outlet 23, and described piston lower end is less than the gas outlet, and the piston upper end is greater than the gas outlet.When heating up water, steam makes the gas outlet open ventilation the piston jack-up that makes progress, and when not heating up water, piston self descends and blocks the gas outlet.Be provided with by steam at the kettle top and push the gas outlet that piston is realized automatic open and close, be used for row's steam when heating up water, be used for insulation after heating up water, this structure rear discharge because of a large amount of steam of having avoided heating up water is pulled away heat, but also can utilize steam to keep water temperature.Described gas outlet 23 is counterbore.Make the electric kettle outward appearance more attractive in appearance.
Such as Fig. 1, described kettle body 1 comprises shell 11 and places the interior inner bag 12 of shell that be provided with vacuum layer 15 between shell 11 and inner bag 12, described vacuum layer is the closed cavity that is evacuated.Vacuum layer can play good adiabatic heat-insulation effect.Adopted the vacuum heat-preserving mode, 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, guaranteed that simultaneously the kettle body case is normal temperature, the protection user can not be burned.
Such as Fig. 1, filled and process material between described vacuum layer 15 and shell 11 forms the heat-insulation layer 14 of being made by cellular insulant, further prevents heat loss.
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.
At the kettle body 1 interior temperature control circuit that arranges, the water temperature in the kettle body inner bag 12 is controlled at 80 ℃, 82 ℃, 83 ℃, 85 ℃, 86 ℃, 88 ℃, 90 ℃, 92 ℃ or 95 ℃.The user can select according to actual needs, water temperature can be remained on always 95 ℃ of temperature of required optimum such as kettle during drinking kung fu tea, 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 85 ℃ vacuum heat insulation type electric kettle; 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 ℃.
