Description
Technical field:
The present invention relates to a kind of heater, particularly a kind of chemistry, biology laboratory are used for the water-bath of utensils such as water-bath heating beaker, test tube.
Background technology:
Water-bath is chemistry, the biology laboratory of school, and in industry scientific research, production and the teaching processes such as chemical industry, food, epidemic prevention, medicine, biological products to material particularly to the evaporation of heat sensitive material, concentrate, crystallization, drying, widely used, the requisite heating instrument equipment of impregnating process.The water-bath that uses at present comprises shell, control circuit, pot body and heater element, and heater element is an electric heating tube; Heat-generating pipe is installed in pot body near the bottom, and heat-generating pipe is communicated with control circuit, and control circuit is through the break-make of electric current or the size of the electric current that control is passed through in the temperature controller control heat-generating pipe, to keep water temperature in the pot body in suitable temperature.The heater element of this type water-bath is a resistance element, and the thermal efficiency is lower, and the heater element of electric heating one is close with pot a body, housing contacts, and especially insulating materials is prone to lose efficacy and causes pot body charged under the high temperature, is prone to take place personal injury accident.
Though the existing before this patent No. is 200820211436.5 utility model have been solved insulating materials and is prone to lose efficacy and causes the charged problem of pot body; But it can only use ferrimagnet pot bodies such as stainless steel; Can not use nonmetallic materials pot body, thereby limit pot body material chosen.In addition for can observe the material heating state; There is one type to be the transparent water bath in the water-bath; And transparent nonmetallic materials such as glass, the lucite indispensable pot body material that all is transparent water baths; So the transparent water bath still need adopt heat-generating pipe as heater element, still can lose efficacy because of insulating materials causes the electric heating tube electric leakage that personal injury accident takes place.
Summary of the invention:
The object of the invention is exactly the above-mentioned defective that will overcome prior art, and a kind of efficient, safe electromagnetism heating nonmetal pot body water-bath is provided.
For achieving the above object; Electromagnetism heating nonmetal pot body water-bath provided by the invention; Comprise shell and pot body, also comprise the heat-generating disc in control circuit, coil and the pot body in the said shell, it is characterized in that coil produces alternating magnetic field and makes said heat-generating disc produce eddy-current heating.Said pot body is bearing in the top of said shell, and said coil stationary is installed in the below of said pot body bottom surface and links to each other with said control circuit electricity, and said heat-generating disc is fixedly mounted on the bottom surface in the said pot body corresponding with said coil.
Electromagnetism heating nonmetal pot body water-bath of the present invention, wherein said coil in one plane in the shape of a spiral the line formula be coiled into coil panel, the number of said coil is 1～4, is distributed under the said pot body bottom surface.
Electromagnetism heating nonmetal pot body water-bath of the present invention, the used lead cross section diameter of wherein said coil is 2.5 millimeters, by stranded the forming of the high temperature resistant enamel covered wire of multiply, the appearance of said coil has resin-sealed layer.
Electromagnetism heating nonmetal pot body water-bath of the present invention, wherein said pot body is the heatproof nonmetallic materials, transparent heatproof nonmetallic materials such as glass, lucite, opaque heatproof nonmetallic materials such as fiberglass, PVC, PP etc.
Electromagnetism heating nonmetal pot body water-bath of the present invention, the heat-generating disc in the wherein said pot body is circular stainless steel thin slice, thickness 1～2mm, somewhat larger in diameter is in the diameter of corresponding coil panel.
The advantage and the good effect of electromagnetism heating nonmetal pot body water-bath of the present invention are: owing to be that coil generation alternating magnetic field makes the heat-generating disc on pot body inner bottom surface produce eddy-current heating; And the heat-generating disc quality is little; So thermal inertia is little, the water heating-cooling rapidly behind the switching electricity in the pot body; Nonmetallic materials pot body cost is low and can process the transparent water bath, the bottom of pot body thin thickness, and the gap is little between heat-generating disc and the coil, so electric conversion efficiency is high, saves electric energy more; Easy to maintenance, service life is also long.Simultaneously because the coil integral sealing and and heat-generating disc between the insulation of nonmetallic pot body is arranged, electric heating is isolated fully, thereby security performance improves greatly, has guaranteed user's personal safety.
To combine embodiment to be elaborated below with reference to accompanying drawing.
Description of drawings
Fig. 1 is that the master of electromagnetism heating nonmetal pot body water-bath of the present invention looks cutaway view;
Label among the figure: 1 shell, 2 pots of bodies, 3 control circuits, 4 coils, 5 heat-generating discs.
The specific embodiment
