Abstract
The utility model discloses a heat preservation electric kettle and belongs to the field of electric kettles. The heat preservation electric kettle mainly comprises a circular kettle body which is encapsulated with a kettle opening and a kettle mouth, wherein an electrical heated pipe is arranged in the kettle body. The heat preservation electric kettle is characterized in that the kettle body consists of a shell and an inner container; the shell and the inner container are sealed and form a vacuum seal cavity through a vacuum exhaust mouth; a heat insulation support is arranged between the shell and the inner container; and an annular reinforcing rib is arranged on the inner wall of the shell. The heat loss is reduced farthest, the thermal efficiency of the electric kettle is high, the heat preservation time is long, and the heat preservation electric kettle has the effects that the structure is simple, the use is convenient, the practicability is strong, and the use cost is low.
Description
Technical field
The utility model belongs to the electric kettle field, is a kind of electric kettle with heat insulation function specifically.
Background technology
Electric kettle has obtained using widely in daily life at present, and it is convenient, the environmental protection scope of application is wide, is subjected to everybody welcome deeply.Present electric kettle is generally individual layer stainless steel kettle body, installs electric heating tube additional in the kettle body.Because in adding the process of hot water, individual layer kettle body surface layer temperature and water-in-kettle are synthermal, cause heat energy a large amount of in the process of heating to run off, thereby reduced the efficient of electric kettle, the thermal efficiency of COMPREHENSIVE CALCULATING common electrical hot-water bottle has only about 60%.
Summary of the invention
The thermal-insulation electric heating kettle that provides a kind of thermal efficiency high is provided the purpose of this utility model.
The utility model is achieved in that
Thermal-insulation electric heating kettle, mainly comprise the circular kettle body that is packaged with Hu Kou, Hu Zui, the electrothermal tube that links to each other with external power source is installed in the kettle body, it is characterized in that: described kettle body is made up of shell and inner bag, seal and pass through the vacuum pumping mouth formation vacuum-sealed cavity of bottom between shell and the inner bag, be provided with heat insulated supporter between the shell of bottom and the inner bag; An ancient piece of jade, round, flat and with a hole in its centre is provided with ring stiffener in the shell in the vacuum-sealed cavity.
After the utility model adopts said structure, the blacking layer of inner bag inner surface can improve the absorption efficiency from the shell radiant heat energy, the minute surface bright layer of outer surface of outer cover can reflect back inner bag to extraradial energy, vacuum design between inner bag and the shell can reduce the air heat-transfer effect, thereby reduced convection heat transfer' heat-transfer by convection, reduced the loss of heat to greatest extent, electric kettle thermal efficiency height, temperature retention time is long.Have effect simple in structure, easy to use, practical, that use cost is low, can be widely used in the daily life.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Among Fig. 1,1 is that Hu Kou, 2 is that Hu Zui, 3 is that electrothermal tube, 4 is that shell, 5 is that inner bag, 6 is that reinforcement, 7 is that vacuum pumping mouth, 8 is heat insulated supporter.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
The utility model electric kettle mainly comprises the circular kettle body of being made up of shell 4 and inner bag 5, and sealing forms vacuum-sealed cavity between shell 4 and the inner bag 5.Inner bag 5 uses food-grade stainless steel press formings, and to processings of turning black of the inner surface of inner bag 5, formation one deck blacking layer can improve the absorption efficiency from shell 4 radiant heat energies again.Outside at inner bag 5 is shell 4, is made by mirror face stainless steel, forms one deck minute surface bright layer at shell 4 outer surfaces, inner bag 5 can be reflected back to extraradial energy.Be provided with vacuum pumping mouth 7 in the bottom of electric kettle, be used for extracting out the air of vacuum-sealed cavity between shell 4 and the inner bag 5, reduce convection heat transfer' heat-transfer by convection thereby vacuum-sealed cavity can reduce the effect of air heat transfer, improve the thermal efficiency.Be provided with heat insulated supporter 8 between the shell 4 of bottom and the inner bag 5, to strengthen the support strength of 4 on inner bag 5 and shell; An ancient piece of jade, round, flat and with a hole in its centre is provided with ring stiffener 6 in the shell 4 in the vacuum-sealed cavity, to guarantee that shell 4 is indeformable when vacuumizing.Kettle body upper end is packaged with kettle mouth 1, and side package has kettle mouth 2.Side lower part at inner bag 5 and shell 4 has installing hole, by this hole electrothermal tube 3 is installed in kettle body inside, and electrothermal tube 3 links to each other with external power source.Installing hole, kettle mouth 2 installing holes and kettle mouth 1 edge by electrothermal tube 3 between shell 4 and the inner bag 5 link to each other.
Electric kettle is supporting in addition supply socket, kettle handle, a vacuum double pot lid, has venthole on the vacuum double pot lid.Shell 4 bottoms are provided with the base of being made by adiabatic bakelite.
