Abstract
The utility model relates to a vacuum thermal insulating electric heating household utensil, which adopts a vacuum chamber body between a metal inner liner and a casing as insulation construction. A vacuum tube is typically arranged on the casing whose bottom part is provided with a base. The utility model is characterized in that an insulation layer and electrothermal elements are arranged in the vacuum chamber body and at the point attached to the metal inner liner, corresponding electric heating lead electrodes are arranged on the casing or/ and the base, and additionally, electrothermal temperature controlling elements are also arranged at the bottom of the outer side of the metal inner liner to be staggered with setting positions of the electrothermal elements.
Description
The utility model can be as bottle, cup, pot etc. about a kind of electric heating thermal insulation vessel.
At present, vacuum flask is except the easy broken structure of this class of glass evacuated glass liner, this infrastructure product of vacuum chamber thermos cup that also useful stainless steel is made, corresponding those electric heating utensils in addition, comprise electric heat insulating pot, electric cooker etc., the insulation of these electric heating utensils all is to adopt solid foamed or fiber heat preservation material as thermal insulation layer, the clear-cut insulation layer that does not just have truly that has, for holding temperature, adopt small-power to be interrupted the deficiency that heating remedies radiating and cooling.
The purpose of the utility model is exactly will overcome the deficiency that above-mentioned prior art exists and design a kind of vacuum heat-preserving electric heating utensil with highly reliable insulation and high efficiency of heating surface.
This vacuum heat-preserving electric heating utensil adopts the vacuum cavity that constitutes between metal inner tube and the shell as the insulation construction setting, vacuum-pumping tube generally is set on shell, the bottom is provided with base, be characterized in vacuum cavity and be attached to the metal inner tube place being provided with insulating barrier and heating, corresponding electric heating lead electrode is arranged on shell or/and the base, in addition, the electric heating temp-controlling element also is arranged on and with heating the position is set on the metal inner tube exterior bottom and staggers.
Of the present utility model further the setting is that heating is sealed wherein by metal inner tube and reflection heat conduction baffle plate, and leaves the space between reflection heat conduction baffle plate and the shell.
The utility model of said structure characteristics utilizes the metal inner tube heating to make things convenient for characteristics, be aided with vacuum heat-preserving, and heating element heater is set in vacuum chamber, to greatly improve electrical heating efficiency, set up reflection heat conduction baffle plate again and promptly improved the thermal efficiency and overcome heat radiation and influence the case thermal insulation effect, overcome the hidden danger that the decomposition exhaust reduction vacuum that causes because of hot high temperature because of heating and insulating barrier influences the heat-insulation and heat-preservation effect again.
Further illustrate the utility model below in conjunction with description of drawings, provide embodiment simultaneously.
Fig. 1 is the utility model example structure cutaway view.
Wherein 1, metal inner tube; 2, shell; 3, vacuum cavity; 4, insulating barrier; 5, heating; 6, electric heating temp-controlling element; 7, vacuum-pumping tube; 8, electric heating lead electrode; 9, reflection heat conduction baffle plate; 11, getter; 12, container chamber; 13, base; 14, change-over switch; 15, electric heating lead electrode.
As shown in the figure, in the present embodiment, metal inner tube 1 and shell 2 build up the cavity of sealing by welding, promptly become vacuum cavity 3 after inserting vacuum, certainly, metal inner tube 1 can be constructed vacuum cavity 3 by drawing and forming with the shell 2 that is metal equally, in shell 2 bottoms or other position be provided with vacuum-pumping tube 7 and electric heating leadout electrode 8, getter 11 places in the vacuum cavity 3, generally be fixed on shell 2 inwalls, heating 5 is attached on metal inner tube 1 outer wall by insulating barrier 4, the reflection heat conduction baffle plate of setting up 9 seals heating 5 wherein with metal inner tube 1, the heat radiation of heating 5 can not had influence on the shell, promptly improve the thermal efficiency, the excessive gas of accident that the high temperature when preventing because of heating 5 heating again causes influences the adiabatic effect of heat insulation reduction phenomenon that vacuum causes.The utility model is with heating 5, temp-controlling element 6 all places in the vacuum cavity 3, eliminated the oxidation hidden danger of electrical equipment, to improve greatly its service life, but simultaneously to just in case the electrical equipment phenomenon of the failure that occurs, be difficult to accomplish in time maintenance process easily, Given this, two cover heatings 5 are set present embodiment or/and temp-controlling element 6 places vacuum cavity 3, also supporting as required two cover electric heating lead electrode 8 or/corresponding with it with change-over switch 14, change-over switch 14 generally is located on the base 13, certainly, this scheme should have three kinds of assembled state, and it two is that three cover heatings 5 overlap temp-controlling element 6 with one; It three is that two cover temp-controlling elements 6 overlap heating 5 with one, these schemes also should belong to the utility model scope, in addition, electric heating temp-controlling element 6 is except being arranged at this scheme of metal inner tube 1 exterior bottom, also it can be arranged on the hinged cover cap of shell 2 on, this mechanism is specially adapted to electric cooker, electric hot water bottle etc. when being provided with have on the electric heating utensil of cover cap.
