Major and minor heater (4) (7) adopts and to fill the heater that the electric heating tube of refractory insulating material, outer ingot metal material are made in the heating wire, major-minor heater (7) (4) or adopt ptc heater; Secondary heater (7) or adopt heater strip, external insulation, fire-resistant, heat-storing material are made calandria.
Separate between the major and minor heater (4) (7), part connects or welding, the part contact by regulating the interval of contact portion between two heaters, noncontact part, or adds adiabatic, refractory material, the thermal resistance and the heat of regulating between two heaters are transmitted.
Temperature control system, this system adopts independent or the merging control mode to two hot devices (4) and (7); Double boiler body (1) internal layer is provided with bimetallic, magnetosensitive or thermally sensitive temperature sensor (2), directly contact with interior pot, directly or through control relay circuit control primary heater (4) separately, or control major and minor heater (4) (7) simultaneously, when being used as direct control, can realize the temperature control of heter temperature set point,, can make electric heater and start preceding permanent disconnection control once more through the circuit of relay, magnetic cylinder is set; Secondary heater (7) is provided with bimetallic, magnetic cylinder or thermally sensitive temperature sensor, through control circuit directly or through the control circuit of relay is set, secondary heater is provided with temperature spot to be repeated control or restarts preceding permanent disconnection control, secondary heater or employing time control mode, machinery or electronic timer and circuit are set, secondary heater stops heating after reaching design temperature voluntarily, or repeats to restart heating behind the certain hour.
Adopt overtemperature or overload fuse protection device (13) in the heater circuit, and interior pot (3) is when leaving heater (4), the outage safeguard protection that mechanical displacement formula telegraph key (9) takeoffs.
Pot body (1) ectonexine space, bottom, secondary heater bottom, heat-insulation material is set, or constitutes the air adiabatic layer.
Compared with prior art, the utlity model has following advantage:
Because of adopting major and minor heater split, combining structure and corresponding multiple spot, multi-object TEMP control system, security system, can control the thermal characteristics in each stages such as middle heating, constant temperature, insulation of cooking, make rice obtain abundant congeeization, not burntly not stick with paste energy-saving heat preserving.
Below provide the utility model embodiment and accompanying drawing, describe this in detail and be suitable for novel structure and operation principle.
