Abstract
The utility model relates to the technical field of the electric stove. The electric stove of the utility model is characterized in that a heating element of the utility model is a graphite heating body which is fixed in an insulating and heat conducting body and has no contact with the air, and the graphite heating body is connected with a power cord. Compared with the existing electric stove, the utility model has the advantages of high efficiency, power saving, rapid elevation of temperature, no noise, no open flame, no light consumption, endurance of dry heating, long service life, simple structure, low cost, convenient installation and maintenance, etc.
Description
The utility model relates to a kind of furnace technology field.
Its heater element of existing electric furnace all uses the metallic resistance silk, and there are many shortcomings in metallic resistance silk electric furnace, and, life-span low as thermal conversion rate is short, power consumption is big, easily oxidation, poor safety performance, stove silk are easily broken etc.Recently also have and adopt the electric furnace of Electric radiant Heating Film as heating element heater, but this Electric radiant Heating Film can not dry combustion method, the life-span is short, is difficult for repairing, thereby also is not used widely.
The purpose of this utility model is a kind of novel electric furnace of design, it can overcome the defective of existing electric furnace, have economize on electricity, quick heating, noiseless, pollution-free, the flames of anger, unglazed consumption, but dry combustion method, power and heating temp can be regulated as required, and be simple in structure, and cost is low, long service life, advantage such as installation and maintenance are easy.
The technical scheme of this utility model is: the heating element heater of this electric furnace is a graphite heater, and it is fixed in the insulating thermal conductor, does not contact with air, and graphite heater links to each other with power line.Graphite heater is formed by graphite or the compacting of graphite compound body, graphite is that the carbon that contains more than 99.9% is formed, can be made into different-thickness and difform heater element through processing, promptly make the graphite heater band of continuous strip according to furnace volume, its watt level is provided with as required.Graphite heater is sintered or otherwise is fixed in the insulating thermal conductor, same air insulated.Insulating thermal conductor is the body of heater of electric furnace, and it is made by the nonmetallic materials that can transmit heat again rapidly with insulating properties.As pottery, silicate etc.In order to make electric furnace adjustable power in use, on power line, be provided with the controllable silicon power governor, its effect is to regulate the furnace power size, power regulating range is provided with as required.For the thermal efficiency that makes electric furnace is higher, be provided with insulating in the insulating thermal conductor bottom of electric furnace, it is made by refractory material, as perlite or alumina silicate fibre etc.In order further to reclaim the energy that far infrared distributes, on boiler face, preferably apply one deck far ultrared paint, far infrared is transformed into heat energy discharges.In order to prevent to break after the heating of insulating thermal conductor and boiler face, on insulating thermal conductor and boiler face, be provided with inflation port, it also can reclaim the bottom dispersed heat by cross-ventilated form.Boiler face can be made into the plane according to the different purposes of electric furnace, also can be made into concave surface, and the electric furnace of concave surface is suitable for doing electric cooking appliance.Because boiler face is made with the material of insulation, be coated with far ultrared paint again, thereby boiler face is non-conductive, and is safe in utilization.
During use, with the power connection of power line, graphite heater then begins heating, and heat is delivered to boiler face through the insulation heat carrier, passes to heated object or the air from boiler face again.This electric furnace and existing electric furnace relatively have following advantage: 1, efficient electricity-saving, and the thermal efficiency can reach about 90%; 2, quick heating, noiselessness, pollution-free, the flames of anger, unglazed consumption, but dry combustion method; 3, power and heating temp can be regulated as required; 4, the heater element does not contact with air, and oxidation does not take place, so long service life; 5, simple in structure.Cost is low.Installation and maintenance are convenient, are the renewal products of existing electric furnace; 6, this electric furnace is as cooker, its applicable difformity, unlike material be heated container.
Accompanying drawing 1 is a structural representation of the present utility model, also can be used as the example structure schematic diagram.Fig. 2 A-A profile is showed the internal structure of electric furnace more clear.
In the accompanying drawing 1,1, insulating thermal conductor, it is made with ceramic material, is commonly called as stone or metal plate for standing a stove on as a precaution against fire; 2, graphite heater; 3, controllable silicon power governor; 4, inflation port; 5, insulating adopts the manufacturing of alumina silicate fibre material; 6, far ultrared paint layer.
