Detailed Description
the following detailed description of the present invention is made with reference to the accompanying drawings. As shown in fig. 1-2.
Example 1: the vacuum electric heating kettle comprises a shell, an inner container 2, a base 5 and a heating device, wherein the upper end of the inner container 2 is welded with the upper end of the shell, a heat insulation space is formed between the shell and the inner container 2, and the heat insulation space is vacuumized; heating device includes heating plate 3, and the lower extreme of heating plate 3 is equipped with interface 10, heating plate 3 is located the bottom of inner bag 2, and inner bag 2 and casing all are equipped with interface 10 matched with through-hole, interface 10 stretch out the through-hole and with 11 electric connection of plug of base 5.
This technical scheme adopts and sets up heating plate 3 in inner bag 2 bottoms for can directly heat water during the heating, heat-conduction is fast, heating effect is good. Secondly, in the installation process of the heating plate 3, the heating plate 3 can be put in from the kettle opening, and the interface 10 penetrates out of the through hole at the bottom; because the heating plate 3 is electrically connected with the bottom plug 11 through the interface 10, when the water temperature dissipates heat, the heat is basically radiated outwards mainly through the heating plate 3 and the through hole; the interface 10 can be designed to be relatively small, so that the area of external heat radiation can be effectively reduced. The heating plate 3 can adopt the prior art, such as the heating plate 3 of an electric cooker.
Further, the shell comprises a side shell 1 and a bottom shell 7, the base 5 is provided with an annular wall 14, an annular gap is formed in the outer side of the upper end of the annular wall 14, the bottom shell 7 is provided with an annular side wall 16, the lower end of the side shell 1 and the side wall 16 both extend into the annular gap, the side shell 1 is located on the outer side of the side wall 16, and the lower end of the side shell 1 is connected with the side wall 16 in a sealing mode.
In the technical scheme, in order to improve the sealing performance, the annular notch is arranged on the annular wall 14 of the base 5, the side wall 16 and the side shell 1 are accommodated in the annular notch, the side wall 16 is clamped and pressed by the annular wall 14 and the side shell 1, the contact area between the side wall 16 and the side shell 1 is large, and the sealing performance can be improved.
Further, the upper end of the annular wall 14 is provided with a clamping hole, and the side wall 16 is concave to form a clamping protrusion 15 matched with the clamping hole.
After the annular wall 14 is provided with the clamping hole, the side wall 16 and the annular wall 14 form clamping connection; preventing the side wall 16 from disengaging from the annular wall 14.
Still further, the lower end of the side wall 16 is bent outwards to form a gasket 13, and the gasket 13 is connected with the lower bottom surface of the annular wall 14.
After the spacer 13 is formed on the side wall 16, the side casing 1 is connected with the side wall 16 only in contact, so that a large gap formed between the side casing 1 and the annular wall 14 due to different materials can be avoided.
Referring to fig. 3, further, an annular cushion block 8 is arranged between the bottom of the heating plate 3 and the bottom of the inner container 2.
Set up annular cushion 8 for with heating plate 3 and the separation of inner bag 2, avoid heating plate 3 directly to inner bag 2 heating, inner bag 2 temperature rise is too high, arouses great expend with heat and contract with cold reaction, destroys the leakproofness. When specifically setting up, the lower extreme middle part of heating plate 3 is the downward concave yield and is formed annular butt portion, and the top of annular butt portion forms installation space, and installation space is connected with the upper end cooperation of interface, and annular butt portion's lower terminal surface passes through the bottom butt of annular cushion 8 with inner bag 2.
