Abstract

The utility discloses a bunchy and multiturn heating coilpanel comprising a bunchy and multiturn heating coil, a ferrite core and a fixed support. The coil utilizes coils of different diameters that is a small, a middle and a big diameter coil coiled up by tens of twisted high strength lacquered wire, and each coil is generated to a bunch and fixedly displaced to a concentric circle on the support with regularly space, the three bunchy coils is capable to fix on a plane and applicable for pans, also is capable to fix on a concave surface and applicable for pans with arc bottoms. L shape magnetic cores arranged onthe inner side and bottom of each coil make three vortex loops of various sizes formed on the bottom of a pan, thereby three circularity heating tapes are formed on the pan bottom to make the heating equal and the heating area big. With magnetic cores in the bunchy coils, the coil turns can be reduced as well as copper loss, the magnetic concentration is increased, and the influence from the big coil to the small coil is reduced. The induction cooker made up by the coilpanel with a power of 2.8KW is particularly applicable for cooking dishes in home.

Description

Pencil multi-turn heater coil disc

Technical field

The utility model relates to a kind of being applicable to than the high frequency heating coil dish that uses in high-power electromagnetic oven and the similar device, particularly a kind of pencil multi-turn heater coil disc.

Background technology

Carry out the electric calorifie installation extensive application of high-frequency heating by coil device, popular family expenses electromagnetic oven especially at present, its electro-heat equipment mainly adopts single coil panel.Because the bottom of a pan is tabular, the high-frequency current of coil panel produces eddy current in tabular conductor, its physical characteristic is mobile towards the road of resistance minimum, form minor loop, although single coil panel area is big, the eddy current area only forms a heating circle that diameter is about 10 centimetres much smaller than the coil panel area in the bottom of a pan, 50 square centimeters of heating area less thaies, it is inhomogeneous that the bottom of a pan is thermoae.

Existing market has a kind of employing dicyclic heater coil disc in addition, and fecund is given birth to a heating circle, and the heating uniformity makes moderate progress, but because family expenses electromagnetic oven body structure limitation, be not easy to increase number of rings, the bottom of a pan thermal uniformity and heating surface (area) (HS are still not ideal enough again, are necessary to improve.

Summary of the invention

The utility model provides a kind of can form a plurality of eddy current circles in the bottom of a pan, produces the pencil multi-turn heater coil disc in a plurality of pili annulatis torrid zone.Make the bottom of a pan heating surface (area) (HS big, heat is even, and the coil panel of this structure is convenient to strengthen electromagnetic oven power, is beneficial to the vigorous fire cooking.

Pencil multi-turn heater coil disc by this purpose design comprises a plurality of pencil heater coils, FERRITE CORE, and coil bracket.Its architectural feature is: be provided with two pencil coils that above diameter is similar and different at least, circle is fixed on the coil bracket as required with circle, and keeps a determining deviation mutually, and skeleton can be made plane or concave surface according to form of pot bottom.Available series system connects between each circle of pencil coil, also can control respectively by circuit, and also the mode of available strings combination in parallel connects.Coil adopts the stranded coiling of multiply high strength enamelled wire, and the surface area increase is beneficial to and improves the Q value.The pencil coil can make things convenient for the multiple shape of coiled as required, as ellipse, semilune, fan-shaped, square etc.

Above-mentioned pencil coil respectively encloses the inboard and L shaped magnetic core is equipped with in the bottom, the inductance coil that is added with magnetic core can reduce the number of turn under equal inductance value, big electric current reduces copper loss down, improve some efficient, the magnet accumulating cap of magnetic core make the magnetic line of force more concentrated, influence each other between reducing the pencil circle and enclosing, also reduce leakage field simultaneously.

The utility model is owing to adopt the structural manufacturing process of pencil multi-turn can produce a plurality of eddy current circles, and consequently the bottom of a pan heating surface (area) (HS is big and heat is even, and effect was fine when the electromagnetic oven about the 2.8KW that makes with this coil panel was used for the vigorous fire cooking.

Embodiment

Below in conjunction with drawings and Examples the utility model is further described.

Referring to Fig. 1, Fig. 2, Fig. 3, this pencil three circle heater coil discs, by the big coil 3 of pencil, middle coil 4, small coil 5, and L shaped magnetic core 6,7,8 formations, and be fixed on the support 9.

This pencil three circle heating spool rests are that electromagnetic oven heating coil total inductance amount is divided into the coiling of three circles, and each encloses some circles and is bundled into bundle, are fixed on the spill cambered surface support referring to Fig. 2 again, also can be fixed on the planar bracket referring to Fig. 3.Coil panel top is 2, and end is 1.

This embodiment big coil 3 inboards and the end, are equipped with L shaped magnetic core 8, many magnetic cores equidistantly distribute, and spacing is set according to poly-magnetic degree needs between magnetic core, and L shaped magnetic core 7 also is equipped with at middle coil 4 inboards and the end, magnetic core also is equidistantly to distribute, and inner ring 5 inboards are equipped with the circular hollow post and are connected base magnet ring 6.

According to the technical program, also can be designed to the above multi-turn heating plate of pencil three circle, the geometry of coil can be designed to semilune, fan-shaped, square etc. as required, adapts to the concrete needs of various pans.

This pencil multi-turn heater coil disc can be connected in parallel being connected in series after each coil independence coiling, or the connection in series-parallel mode of combining connects, but also each coil is independently controlled by circuit, adapts to the multiple use utilization.
