The specific embodiment
Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model, the technical characterictic in the utility model can not be combined conflicting in the situation that.
Fig. 1 is interior pot and the assembly structure schematic diagram of electric hot tray of the preferred embodiment of the utility model electric pressure cooking saucepan; Fig. 2 is the structural representation of interior pot in Fig. 1; Fig. 3 is the structural representation of electric hot tray in Fig. 1.
In the prior art, electric pressure cooking saucepan comprises interior pot 1 and also heats the electric hot tray 2 of interior pot 1 for contacting interior pot 1 bottom.Because the temperature of the interior pot 1 of electric pressure cooking saucepan is higher, pressure is larger, therefore in pot 1 actual is in the state for distortion.When the bottom of interior pot 1 is while being easier to plane or other shapes of distortion, easily cause interior pot 1 bottom to arch upward downwards, thereby cause the contact-making surface of interior pot 1 bottom and electric hot tray 2 significantly to reduce, thereby the inequality of being heated that causes interior pot bottom, the Efficiency Decreasing of heating, thus the slack-off phenomenon of heating of wasting electric energy and interior pot 1 produced.
In order to improve in the generation electric pressure cooking saucepan provided by the utility model of above-mentioned phenomenon, the region that the bottom of interior pot 1 contacts with electric hot tray 2 is the arcuation that the high surrounding in middle part is low, and the bottom shape of the upper surface of electric hot tray 2 and interior pot 1 is suitable.
Bottom by interior pot 1 is set to arch cambered surface, and the extrados of arch cambered surface bears pressure, therefore in, the bottom of pot 1 has stronger bearing capacity, thereby under the environment of elevated pressures, the bottom shape of pot 1 remains unchanged substantially, keep preferably degree of laminating with the upper surface of electric hot tray 2 all the time in the course of the work, thereby reach the effect that the bottom of interior pot 1 is heated evenly; Because the bottom of interior pot 1 and the upper surface of electric hot tray 2 are all set to arch cambered surface, therefore in the contact area of the bottom of pot 1 and the upper surface of electric hot tray 2 become larger, conducts heat more smooth, and then makes in 2 pairs of electric hot traies pot 1 the efficiency of heating surface higher.
Preferably, the bottom of interior pot 1 is spherical arcuation.Because spherical extrados is preferably resistance to compression shape, therefore, the interior pot 1 with spherical arcuation bottom will have preferably compressive property.
On the basis of above-described embodiment, preferably, the radius of curvature R 2 of the upper surface of electric hot tray 2 is 500mm to 900mm.The radius of curvature R 2 of the upper surface of electric hot tray 2 arranges too smallly, and the radius of curvature R 1 of the bottom of the interior pot 1 that can make to match is with it also less, thereby makes arching upward of interior pot 1 bottom higher.Conventionally in, pot 1 is all to stretch to form, and because arching upward of interior pot 1 bottom is higher, therefore to manufacturing the requirement of tensile property of the material of this interior pot 1, also improves, and this causes uneconomical on material, and easily produces to pull open and wait the situation generation that reduces production efficiency.The radius of curvature R 2 of the upper surface of electric hot tray 2 arranges too much, the radius of curvature R 1 of the bottom of the interior pot 1 that can make to match is with it also larger, thereby make arching upward of interior pot 1 bottom more flat the end of compared with, thereby the renitent performance in the bottom that causes interior pot 1 is not enough, and cause the 1 bottom deformation of interior pot, and cause with the contact-making surface of electric hot tray 2, reduce.More specifically, preferably the radius of curvature R 2 of the upper surface of electric hot tray 2 is 600mm to 800mm, thereby can take into account the manufacture difficulty that reduces mould, can also make electric hot tray 2 and interior pot 1 hold sense better, the effect more attractive in appearance of visual effect.
Further, in order to improve the heat transfer efficiency of electric hot tray 2 and interior pot 1, preferably, the upper surface of electric hot tray 2 is formed with lines, in order to increase the area of dissipation of electric hot tray 2, thereby more fast heat is conducted to interior pot 1.This lines can be the concentric circles lines on the upper surface of electric hot tray 2, can be to be also centered by the geometric center of the upper surface of electric hot tray 2 to the lines of surrounding emitting shape, and can be also irregular other lines.
The foregoing is only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
