Technical field

The utility model relates to a kind of electric kettle, is meant that especially a kind of its kettle body comprises outer pot body and inner bag body, and centers on the electric kettle of determining a vacuum cavity by the inner surface of this outer pot body and the outer surface of this inner bag body.

Background technology

In recent years, exquisite, practical, electric kettle begins to come into huge numbers of families easily and efficiently, becomes daily life small household appliances articles for use.And it mainly is also simultaneously the liquid in the kettle to be heated by the heat-generating pipe or the electric hot tray energising back heating of kettle bottom with regard to the heating principle of electric kettle, and generally the structure than other electrical equipment is simple relatively for its structural principle with regard to the electric kettle of present appearance.

In daily life, vacuum flask is two kinds of different products with electric kettle, also be separately to use in concrete the use, general user needs at first to utilize electric kettle that boiled then boiled water being poured in the vacuum flask of water just can be reached heat preservation effect.This occupation mode uses extremely inconvenient, the product of this type of problem has also appearred solving on the market, but because most product just utilizes the method for heating repeatedly to solve heat insulation function on heat insulation function, and heating brings new problem repeatedly, and that is exactly the water security problem.After water is heated repeatedly, the water quality sclerosis, the water quality variation can not be drunk.With regard to aforesaid problem, vast kettle manufacturer has studied a large amount of methods and has solved the problem that the kettle heat scatters and disappears, relatively typical method is to adopt the mode that increases thermal insulation layer thickness to promote heat insulation effect, or adopt the mode that improves insulation layer thickness to solve the problem that heat scatters and disappears, but by such conventional method, the effect that solves the lost problem of heat is not fairly obvious.

Summary of the invention

This reality is novel to provide a kind of vacuum electric heating kettle, it comprises pot lid and kettle body, this kettle body comprises outer pot body, inner bag body, heat-generating disc and energising base, and should stew outward body and this inner bag body make the utility model reach the purpose of heat-insulation and heat-preservation around determining a vacuum cavity by this vacuum cavity.

The technical solution adopted in the utility model is: a kind of vacuum electric heating kettle, it comprises pot lid and kettle body, wherein, this pot lid is that lid is located on this kettle body, this kettle body has Hu Kou and Hu Zui, this Hu Zui connects the edge that is arranged on this Hu Kou, and this Hu Zui is connected with this Hu Kou, this pot lid comprises kettle lid piece and pot lid handle, this kettle lid piece is positioned at the lower end of this pot lid, and this pot lid handle is connected this pot lid one end, and this kettle lid piece lid is located on this Hu Kou of this kettle body, is provided with the inclined-plane with respect to this kettle lid piece of this Hu Zui of this kettle body.

This kettle body comprises outer pot body, inner bag body and heat-generating disc, wherein, this heat-generating disc is fixedlyed connected with this inner bag body, this inner bag body has inner surface and outer surface, and add hot-water cavity around determining one by this inner surface, the body of should stewing outward is set in the outside of this inner bag body, and this outer pot body has inner surface and outer surface.

Be separated with distance between between this inner surface that should outer pot body and this outer surface of this inner bag body, and center on by this outer surface of this inner surface of this outer pot body and this inner bag body and to determine a vacuum cavity, this vacuum cavity is wrapped in this outside that adds hot-water cavity.

Aforesaid this heat-generating disc is arranged on the below of this inner bag body, and is connected on the outer surface of this inner bag body.

Be connected with vacuum-pumping tube on aforesaid this vacuum cavity, an end and this vacuum cavity of this vacuum-pumping tube connect.

This heat-generating disc also links into an integrated entity with heating wire and heat shield successively from top to bottom as mentioned above.

Aforesaid this kettle body bottom is provided with anti-dry heating temperature controller and water temperature is responded to temperature controller, boiling point temperature controller, power on/off relay.

The beneficial effects of the utility model are: the utility model is the Vacuum cooker body that has the rust steel to make shell and inner bag with two-layer.Confined space between shell and the inner bag is pumped into the high vacuum state, makes it have remarkable heat-insulating property, and makes it besieged at the bottom of heater is placed on kettle, reduces and conducts heat energy to external world.In the middle of the process of heating, water almost is in by isolated state with extraneous, so the heat energy of heater all is used for adding hot water, compares with general electric kettle, plays the function of energy-saving consumption-reducing.And kettle outward almost with the same temperature in the external world.After heating finished, kettle just was in the middle of the keeping warm mode at once, and minimizing is put into the thermo jug process and the heat energy of loss by the common electrical hot-water bottle after being heated because of water.Because the brilliance of product heat-insulating property of the present utility model just need not heat the living needs that can satisfy daily people after poach is opened again, and water quality can variation.
