Abstract
The invention relates to a thermal-radiation-proof induction cooker coil panel which comprises a mica sheet, an aluminum plate and a coil panel body which is fixed to one face of the mica sheet. The aluminum plate is fixed to the other side of the mica sheet through a magnetic bar. A sensing support is fixed to the coil panel body. A heat insulating device is arranged on the sensing support and comprises a silica gel sheet and a heat insulating plate. The silica gel sheet is fixed to one face of the heat insulating plate and in contact with the coil panel body in a fixed mode. The heat insulating device is installed on the coil panel body and can absorb thermal radiation. The thermal-radiation-proof induction cooker coil panel has the advantages of resisting thermal radiation and being high in reliability.
Description
Technical field
The present invention relates to a kind of coil disc of electric stove of thermal radiation resistant.
Background technology
The boiler face of electromagnetic oven is heat-stable ceramic plate, and alternating current produces magnetic field by the coil of ceramic wafer below, when the magnetic line of force in magnetic field passes the bottoms such as iron pan, stainless-steel pan, produces eddy current, makes the bottom of a pan generate heat rapidly, reaches the object of heated food.Its course of work is as follows: alternating voltage is converted to direct current through rectifier, direct current is become exceed again the high-frequency alternating current of audio frequency through High frequency power conversion equipment, high-frequency alternating current is added on the load coil of flat cored screw shape, produces thus high-frequency alternating magnetic field.Its magnetic line of force penetrates the ceramic platen of the kitchen range top and acts on metal pan.Just there is powerful eddy current to produce at cooking pan internal cause electromagnetic induction.The internal resistance that eddy current overcomes pot body completes the conversion of electric energy to heat energy while flowing, and the Joule heat producing is exactly the thermal source of the cooking.Cooking pan heating temperature raises, can be heat reverse conduction to heat-stable ceramic plate, heat-stable ceramic plate can conduct heat to electromagnetic coil disk, although heat-stable ceramic plate can absorb the heat energy from cooking pan conduction in a large number, but the time has been grown or the breakage of heat-stable ceramic plate, have part heat and be transmitted on electromagnetic coil disk, cause electromagnetic coil disk to be heated and deform, shadow is to the useful life of the coil disc of electric stove of thermal radiation resistant.
Summary of the invention
The technical problem to be solved in the present invention is, a kind of anti-heat radiation, the coil disc of electric stove of the thermal radiation resistant that reliability is higher.
The technical scheme that solves above technical problem employing is as follows, the coil disc of electric stove of thermal radiation resistant comprises that mica sheet, aluminium sheet and fixed coil dish, an another side at described mica sheet fix aluminium sheet by magnetic stripe, on described coil panel, fix sensing support, on described sensing support, establish heat-proof device, described heat-proof device comprises silica gel piece, thermal insulation board, silica gel piece is fixed on the one side of thermal insulation board, and described silica gel piece contacts fixing with coil panel.
All right, stating thermal insulation board is heat insulation brocade.
The invention has the advantages that, adopt above structure knot, add coil panel top heat-proof device is installed, can effectively reduce the heat radiation in the bottom of a pan, reduce the temperature of enamelled wire, improve the reliability of coil panel.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is configuration diagram of the present invention.
Fig. 2 is blast diagram of the present invention.
Embodiment
as shown in Figure 1, 2,the coil disc of electric stove of thermal radiation resistant comprises that mica sheet 5, aluminium sheet 6 and a fixed coil dish 4, another side at described mica sheet 5 pass through the fixing aluminium sheet 6 of magnetic stripe 7, on described coil panel 4, fix sensing support 3, on described sensing support 3, establish heat-proof device, described heat-proof device comprises silica gel piece 2, thermal insulation board 1, silica gel piece 2 is fixed on the one side of thermal insulation board 1, described silica gel piece 2 contacts fixing with coil panel 4, thermal insulation board 1 is heat insulation brocade; Sensing support 3 is fixed with transducer 8, the heat-shrink tube 9 for the end of a thread of coil panel 4.
Operation principle: produce electromagnetic force after coil panel 4 energisings; electromagnetic force produces eddy current while passing iron pan, stainless-steel pan; the internal resistance that eddy current overcomes pot body completes the conversion of electric energy to heat energy while flowing; the Joule heat producing is exactly the thermal source of the cooking; iron pan, stainless-steel pan heating temperature raise, and can produce again thermal radiation, and heat-proof device comprises the radiation that silica gel piece 2, thermal insulation board 1 can attract iron pan, stainless-steel pan to produce; thereby protection coil panel 4, improves its reliability.
