Description
Technical field
The utility model relates to a kind of electric calorifie installation by the coil device heating, especially relates to a kind of tubular coil of electromagnetic oven and similar electric calorifie installation and heater coil disc of disccoil combination of being applicable to.
Background technology
Electric calorifie installation by the coil device heating has a wide range of applications, the most heater coil discs that adopt of especially existing popular electromagnetic oven and similar electric calorifie installation.Existing electromagnetic oven is because the heating inductance coil that adopts mostly is planar disk shape inductance coil greatly, therefore only in the magnetic field intensity peak region that produces small size near the center of coil, and very inhomogeneous for the heating of big pan, be used for cooking be easy to form in afocal give birth to make us not complying with one's wishes phenomenon.Therefore be necessary to be improved.The heater coil disc that existing electromagnetic oven adopts mainly is made up of coil disk body, magnetic core and heater coil, wherein heater coil adopts some circles to constitute the coil panel of an isoplanar concentric, perhaps adopt twin nuclei, or be in same plane or be in two Different Plane, its common ground is to rely closely in same plane between coil and the coil, is fixed on then on one or two the coil disk bodies.According to magnetic field theory, in this heater coil disc of two types, the magnetic field intensity maximum that the centre position of table roller coil produces, thereby form a concentrated magnetic field, it is the center that electromagnetic oven concentrates on the pot heart to the heating of pan, diameter for bigger pan, heats very inhomogeneous less than the discoid thermal treatment zone of 10cm.For the dicyclic heating plate, though occur small one and large one two ring-type heating plates of diameter when pan is heated, but it is because the same with table roller, coil all is plane plate-like coiling, and the coil leakage field is bigger, and the magnetic line of force disperses relatively, in heating ring, magnetic field intensity can't high concentration, and the efficiency of heating surface is under some influence, and the magnetic screen of electromagnetic oven is also relatively poor.Therefore, the table roller formula of every plane plate-like coiling or dicyclic heater coil disc, not fully up to expectations to the effect of pan heating, the magnetic field shielding effect is also relatively poor.
Publication number is that the application for a patent for invention of CN1563807 discloses a kind of electromagnetic oven, comprise body of heater and be arranged on panel on the body of heater, in the body of heater under the panel, be provided with the coil panel heater, panel is hemispherical or arc surfaced, the coil panel that posts under panel is shaped as hemispherical or cambered surface or round table-like, in be inlaid with temperature-sensing probe panel also be provided with 3 to 12 ceramic support posts, this support column and panel are solidified togather and form projection on the surface.
Notification number provides a kind of Inner and outer ring-type heating coil plate for the utility model patent of CN2679958, comprise coil bracket, ferrocart core and heater coil, ring support and outer ring support in its coil bracket is divided into, the heater coil that is arranged on inner and outer ring support and the ferrocart core also is divided into isolated interior heater coil disc and outer heater coil dish.Described inner and outer rings support and inside and outside heater coil disc at grade, or on Different Plane, or on inner concave arc surface at the bottom of the arc pot.Interior heater coil disc connects by mode in parallel or that connect with outer heater coil dish; Heater coil disc is generally the plate-like of indent.
Summary of the invention
The purpose of this utility model is that the heating surface (area) (HS that exists at the existing electric calorifie installation that heats by coil device is little and heats problems such as even inadequately, provide a kind of heating surface (area) (HS big and even, Magnetic Shielding Effectiveness is better, is mainly used in the pipe dish combined heated coil panel in electromagnetic oven and the similar device.
The utility model is provided with heater coil disk body, magnetic core and heating inductance coil, and described heating inductance coil comprises tubular coil and disccoil.
The heater coil disk body is established 1 disk body at least, and disk body can be plane disk body or curved surface disk body or cambered surface disk body.Tubular coil can be located at the inside or the outside of disccoil.Tubular coil is established 1 at least.Disccoil is established 1 dish at least.Magnetic core can be toroidal core, cylindricality magnetic core or strip magnetic core.The heating inductance coil can be individual layer coiling or sandwich wound coil.
Tubular coil and disccoil are positioned on same plane or Different Plane or the cambered surface.The axial line of tubular coil can overlap mutually, and is parallel to each other, cross one another, or its combination, the axial line of tubular coil is perpendicular to the section of flat pan bottom surface or arcuate bottom pan face.Each connection of heating between the inductance coil can be series connection, parallel connection or connection in series-parallel.Each heats inductance coil can be clockwise direction coiling or coiling counterclockwise.The lead number of share of stock of each heater coil preferably is no less than 110.
Magnetic core that the tubulose inductance coil is disposed or magnetic stripe can be located at the inside of heater coil, or inside and bottom, or inside, bottom and the outside.The magnetic stripe that the plate-like inductance coil is disposed then is arranged on the bottom of coil.
Coiling for a plurality of tubular coils can be that 1 tubular coil is followed around other 1 tubular coil around intact again, also can adopt segmentation cross-over connection coiling, promptly just enclose and then around following 1 tubular coil around 1～2 at 1 tubular coil earlier with 1 lead, the coiling that circulates in order is till whole tubular coils wind.This kind winding not only forms several predetermined small-sized tubular coils, also formed by a big tubulose inductance coil forming of jumper repeatedly between each small-sized tubular coil, this big tubulose inductance coil also forms a big ring-type centered magnetic field peak value when work, also just produce a big ring-type heating eddy current circle on pan.It can be to be close to that being provided with between tubulose inductance coil and the plate-like inductance coil is connected, and also can separate some gaps.Each heating inductance coil can also can be divided into groups by separately control of related circuit by the unified control of circuit.The geometric figure of the plane geometric figure of plate-like inductance coil and tubulose inductance coil cross section is circular, half-turn shape, and ellipse, fan-shaped, triangle, quadrangle or polygon etc. and analogous shape.
Because the heater coil of pipe dish combination is made up of at least 2 relatively independent inductance coils, the position that can arrange each inductance coil according to the size and the shape of pan, just can on heated pan, produce at least 2 heating peak region accordingly, bigger more even to the pan heating surface (area) (HS, heats is better, overcome general planar disc heater coil disk fully and be used for the problem that afocal is given birth in the pan cooking generation, be more suitable for being used for frying pan.And the Magnetic Shielding Effectiveness of electromagnetic oven also has clear improvement.
