Abstract
The utility model discloses a low-impedance efficient induction cooker coil panel, which comprises a coil bracket, magnetic strips distributed radially and installed uniformly in the coil bracket, and a coil fixed on the coil bracket, wherein, the magnetic strips are covered with the coil, the coil is formed by winding a hollow flat cylinder-shaped enameled wire fabric body, the enameled wire fabric body is formed by extruding a plurality of enameled wire bundles rearranged and knitted into a cylinder shape, and each enameled wire bundle is made up of a plurality of enameled wires which are arranged side by side. Besides the advantage of compact structure, the utility model achieves large effective current coverage and reduced skin effect, thereby not only reducing power loss, but also improving heating efficiency.
Description
Technical field
The utility model relates to a kind of coil disc of electric stove, especially relates to a kind of low impedance high efficient electromagnetic oven wire winding disc.
Background technology
Electromagnetic oven is to utilize electromagnetic induction principle, the electroheat equipment that produces eddy current and heat in the pan bottom, the coil disc of electric stove of its heater for being made of coil, support, magnetic stripe.The coil of existing coil disc of electric stove by a plurality of enamelling cuprum round line stranded after again coiling form, and then be fixed in and rise on the support of shielding action magnetic field, if after this heater coil passes to high-frequency current, then around this heater coil, produce the magnetic line of force.The coil disc of electric stove of this structure has higher coupling loss, is equivalent to the kelvin effect of normal conductor, and promptly the effective area that flows through of electric current reduces, and the internal impedance of conductor greatly increases, thereby power loss is increased, and has influenced the efficiency of heating surface.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of low impedance high efficient electromagnetic oven wire winding disc, its compact conformation at above-mentioned deficiency of the prior art, the effective area that electric current flows through is big, reduce kelvin effect, thereby reduced power loss, improved the efficiency of heating surface.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of low impedance high efficient electromagnetic oven wire winding disc, comprise coil brace, radially distribute and evenly be installed in the magnetic stripe in the coil brace, and be fixed on the coil brace and cover the coil of magnetic stripe, it is characterized in that: described coil is formed by the enamelled wire knitted body coiling of hollow flat drum shape, described enamelled wire knitted body is replaced fully by a plurality of enamel-cover wire harness and is woven into cylindric after extruding forms, and described enamel-cover wire harness is made of many enamelled wires that are set up in parallel.
Described enamelled wire knitted body is made of 16,24,32 or 48 enamel-cover wire harness.
Described enamel-cover wire harness is made of the 3-7 root enamelled wire that is set up in parallel.
Described coil brace and coil are the plane plate-like.
Described coil brace and coil are the U-shaped arc surfaced.
Described enamelled wire is an enamelling cuprum round line.
The thickness of described enamelled wire knitted body is that 1.5mm and width are 6mm.
The utility model compared with prior art has the following advantages: coil of the present utility model is formed by the enamelled wire knitted body coiling of hollow flat drum shape, and the enamelled wire knitted body is made of a plurality of enamel-cover wire harness that replace fully, like this, electric current is along the enamelled wire knitted body transmission of hollow flat drum shape, be equivalent to electric current and transmit at conductive surface, the effective area that electric current is flow through increases, and has reduced kelvin effect, thereby power loss is reduced, improved the efficiency of heating surface of coil disc of electric stove.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
