Description
Technical field
What the present invention relates to is electric food warmer, especially a kind of energy-saving safety insulation electric food warmer courage.
Background technology
At present, electric food warmer is all kinds of a lot of on the market, has or not the electric food warmer and the electric food warmer that heat insulation function is arranged of heat insulation function.The pot body of the electric food warmer of no heat insulation function exposes in air, the direct and air thermal convection current conduction of pot body, and a large amount of the loss be not so have heat insulation function.And the electric food warmer of tool heat insulation function normally adds heat-insulation layer in the pot body case, utilizes heat-insulation layer to slow down the circulation of pot body and extraneous air, reaches heat insulation function.Yet because the air between pot body and the heat-insulation layer does not seal, air still can be delivered to the outside with the heat of pot body, reduces heat insulation effect, causes energy waste.For making the modal method that the food temperature retention time increases in pot body is to install temperature controller additional, when temperature of boiler drops to design temperature, starts thermoelectric heating device work, heats the purpose that reaches insulation with continuous startup electric heater repeatedly, and this undoubtedly can consumed power.
Chinese patent ZL02272126.6, ZL92100900.3, ZL98215535.2 disclose the electric food warmer of the different tool heat insulation function of three kinds of structures.Adopt the improvement on the different structure, attempt to solve pot low problem of the volume surrounding insulation construction efficiency of heating surface, and heat insulation effect is had some lifting.But in actual fabrication is used, remain in following defective, as: if the inner vacuum structure of making, outer pot must use metal or use glass material directly to weld sealed-for-life in that, not only proposed high request to making to process to vacuumize, also the sealing to external terminal has proposed very high requirement, moreover a lot of materials all can quicken distillation under the vacuum environment, vacuum environment of a specified duration is in case destruction can influence heat insulation effect.It is poor that next is installed in the electrical connector sealing of protecting in the shell, if there is aqueous vapor to immerse, promptly can cause the electric heating system short circuit in the use, can initiation fire when serious.
Summary of the invention
Technical problem to be solved by this invention is the defective that remedies above-mentioned prior art, and a kind of energy-saving safety insulation electric food warmer courage is provided.
The technical problem of energy-saving safety insulation electric food warmer of the present invention is solved by the following technical programs.
This energy-saving safety insulation electric food warmer courage comprises the courage shell, is arranged on the pot body in the courage shell, the thermoelectric heating device that is arranged on bottom of pot body and temperature controller.
The characteristics of this energy-saving safety insulation electric food warmer courage are:
Described courage shell is the container of a diameter greater than the pot body, courage shell bottom lock, and courage shell top is provided with supply bottom of pot body to insert uncovered;
Described pot body is plugged in the courage shell, is provided with the heat-insulating and sealing circle between pot body pot mouth outer wall and courage shell are uncovered, and above-mentioned cooperation makes to be installed between courage shell and the pot body and forms the closed heat insulation chamber;
Described thermoelectric heating device is installed in the bottom of pot body in the closed heat insulation chamber;
Described courage shell be provided with the closed heat insulation chamber in the power supply connecting device that is connected with temperature controller of thermoelectric heating device;
Described courage shell is provided with the Non-return air valve that can regulate closed heat insulation chamber internal gas pressure automatically.When closed heat insulation chamber internal gas pressure exceeds setting pressure, Non-return air valve can be opened automatically and in time the gases at high pressure in the closed heat insulation chamber be discharged, and in time close, guarantee in the closed heat insulation chamber to keep the air pressure set, utilize the gas section of the resistance pot body pot wall closed heat insulation chamber in and the thermal convection current of extraneous air.And guarantee also that when the needs degreasing the pan is outside liquid that can not enters the inside.
The technical problem of energy-saving safety insulation electric food warmer of the present invention is solved by following further technical scheme.
Described power supply connecting device constitutes by being separately positioned on the corresponding one by one socket terminals of inserting column that the power supply of thermoelectric heating device with the temperature controller bottom surface be connected inserting column and be arranged on courage shell bottom and thermoelectric heating device and temperature controller bottom surface, and the bottom surface inserting column of thermoelectric heating device and temperature controller cooperates for insertion with courage shell bottom socket terminals.
Described socket terminals are made up of terminal post, the resilient socket that is nested with the insulated ring on terminal post and is connected terminal post the inner, and the socket terminals are installed in the courage shell bottom through-hole by insulated ring.
For being threaded, that is: terminal post the inner is provided with thread head between described terminal post the inner and the resilient socket, and the pedestal of resilient socket is provided with screwed hole.
Described terminal post is inner little, the pyramidal structure post that the outer end is big, during the terminal post of this structure holds thread head and resilient socket upper screwed hole to screw within it to cooperate, the taper position of terminal post can be oppressed and be overlapped insulated ring thereon, force insulated ring distortion with but being sealed and matched of shell through hole realizes that the sealing of socket terminals in courage shell bottom through-hole install.
Described thermoelectric heating device is resistance heating dish or inductance heat-generating disc.
Be provided with the electric jacket that the electric hot plate that contacts with the applying of pot body pot wall maybe can be placed in the external wall of pot in the described closed heat insulation chamber.It can add the heating of pressure cooker body.
