The utility model has a temperature adjusting device which is connected with a temperature adjusting resistance wire in series and is arranged at the bottom of electric furnace plate. The utility model has the advantages of good energy-saving and power-saving effect, safe and convenient operation, wide purpose, and long service life. The utility model is an ideal heating device for daily life, labs, and scientific research teaching.
Description
The utility model is the improvement to daily electric furnace, is a kind of temperature adjustment Energy-saving electric stove.
We are the most frequently used or what see is the simple electric furnace that is made of stone or metal plate for standing a stove on as a precaution against fire and electric furnace heating wire for daily electric furnace, perhaps add a metal furnaces seat again.But the external temperature of electric furnace is very high when using, and simultaneously a part of heat is scattered and disappeared.For purposes that increases electric furnace and the waste that prevents heat, many purposes and energy-conservation electric furnace have appearred, and each is different for the technical approach of employing.For example on the basis of above-mentioned simple electric furnace, carry out improved Chinese patent 88221647, novel desk-top adjustable electric cooking stove, its major technique is characterised in that one or more layers air-gap between electric furnace pan and shell, separate with support member between electric furnace pan and the shell, though can play certain heat-blocking action, effect is also desirable not to the utmost.The bottom of electric furnace pan in fact temperature is higher, but this part heat do not go to utilize, and also has a problem, and general heating container all is directly to place on the boiler face to heat, and canister contact heating wire is unsafe in use.In order on the basis of above-mentioned simple electric furnace, to reach energy-conservation more fully, use safely and to realize multipurpose, be starting point of the present utility model.
The purpose of this utility model provides a kind of good energy-conserving effect, and is safe and convenient to use, broad-spectrum temperature adjustment Energy-saving electric stove.
Temperature adjustment Energy-saving electric stove of the present utility model comprises electric furnace pan, electric furnace heating wire, is characterised in that electric furnace pan places in the incubation chamber filling heat insulating wall between electric furnace pan and the incubation chamber.
Incubation chamber is made with refractory material, and fire-resistant, insulation is as cordierite.Heat-insulation layer is a light heat insulation material, as, alumina silicate.Adopt double-layer heat insulation, avoided like this heat to around and the bottom spread, improved the coefficient of heat efficency of electric furnace greatly, furnace bottom and case surface temperature reduce significantly, not because of overheated and aging, damage part, improved electric accessories, gauge tap, power supply wiring in its life-span.
The utility model can be installed bracing frame on the electric furnace boiler face, contact with the direct of electric furnace heating wire to avoid canister.Bracing frame can be adjusted to adapt to the size of heating container.
Simultaneously the utility model still can have temperature adjustment function, the different power of conversion as required, thus save electric energy, reduce heat loss.
Describe the utility model in detail below in conjunction with drawings and Examples.
Fig. 1 is a structure half sectional view of the present utility model, also is a most preferred embodiment of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is temperature adjustment tie lines raw material figure;
Among the figure: 1 electric furnace heating wire, 2 temperature regulating switch, 3 temperature adjustment resistance wires, 4 electric furnace pans, 5 heat-insulation layers, 6 incubation chamber, 7 set bolts, 8 stove seats, 9 bracing frames, 10 bracing frame rings, 11 set bolts 12 support hot-face insulation spare 13 hot-face insulation fixed heads 14 set bolts.
Thermosistor is made up of temperature adjustment resistance wire 3 and temperature regulating switch 2, connects between the temperature adjustment resistance wire and connects with electric furnace heating wire 1, and how many temperature regulating switch 2 assembles what according to series connection temperature adjustment resistance wire 3.The utility model is positioned over series connection temperature adjustment resistance wire between the bottom and heat-insulation layer of electric furnace pan 4, makes the heat of stone or metal plate for standing a stove on as a precaution against fire bottom obtain recycling, and plays power savings.Rp represents electric furnace heating wire 1, R in Fig. 3 temperature adjustment elementary diagram

3Be temperature regulating switch, the power of electric furnace changes its watt level with the conversion of temperature adjustment resistance wire series connection resistance.
Bracing frame 9 comprises a bracing frame ring 10, distributing on the bracing frame ring 10 at least three can about push-and-pull support hot-face insulation spare 12, open a slotted hole in the middle of the insulating part 12, and be fixed on electric furnace pan and the incubation chamber by set bolt 11, insulating part 12 just this scope inside outside the push-and-pull adjustment, to adapt to the size that is heated container.Be welded with hot-face insulation fixed head 13 on the bracing frame ring 10, fixed head 13 is below insulating part 12, and punching, mantle fiber on it are convenient to the fixing of set bolt 11.
Incubation chamber 6 is fixed on bakelite matter or the metal matter stove seat 8 by set bolt 7.
Advantage of the present utility model:
1, energy-conservation, power savings good, improves 13.8% than the thermal efficiency of GB5488-85 regulation.
2, safe and convenient to use, arbitrarily temperature adjustment.
3, of many uses, be the desirable heater that daily life and laboratory, research and teaching are used.
4, long service life, easy to maintenance.
