Description

A kind of multi-thread ring type drum for electromagnetic heating

Technical field:

The present invention relates to a kind of electromagnetic coil more particularly to a kind of multi-thread ring type drums for electromagnetic heating.

Background technique:

It is each by scientific research, laboratory, industry and family due to electromagnetic heating not only safe ready, and the high energy conservation of thermal effect The welcome of aspect.As with if on such as baking oven, heating will centainly big heating surface, and electromagnetic heating common at present Equipment and stove etc., mostly only single heating coil, are difficult to meet the balanced heating under large area, in spite of use plus Big single coil increases heating surface, but is confined in single purposes.

Summary of the invention:

The task of the present invention is a kind of multi-thread ring type drum for electromagnetic heating is provided, its heating surface is big, not only can On baking (roasting) case, heater, safety water heater, heater, most probably on electromagnetic oven.

Technical solution of the present invention and measure are: the size and coil size in electromagnetic heating face have direct relation, in consideration of it, In order to keep heating surface big, effective measures are: multiple small coils being arranged in the heating surface of required shape, and have connected that these are small For coil at a big overall coil, the number of these small coils, can how much with required heating surface size and the decision of heated shape To be several or more than ten to tens is differed.They can be arranged in round, ellipse according to required, be also possible to square, It can also be rectangle, how much is the coil number no matter arranged, and total principle is that the total inductance amount after they connect should be with electromagnetic work The inductance of rate output LC resonance matches, and such electromagnetic conversion efficiency highest is also beneficial to power output tube.

Small coil be square arrangement, every number of edges be 3,4,5 etc., rectangle arrangement can with uniline, duplicate rows, three it is capable not Deng how many of, every row according to need depending on；Oval intermediate coil is a little bigger, both ends each one or each three coil dots；Arrangement At circular, it can be that an intermediate coil is a little bigger, several coil dots of its circle above, these small coils can be phase Neighbour's arrangement or flanging or pressure are partly arranged in circle, and small coil number is according to practical determination.It can also be a circle every a circle or one Circle is arranged in the arrangement of a great circle ring type by a circle.When coil be arranged in it is round and when for family's electromagnetism kitchenware, with flat Then coil is planar coil to bottom pot, becomes U-shaped circle with coil when U-shaped pot.As long as small coil accomplishes that U can be formed in change procedure When shape there is retractile function can form U-shaped circle, (lifting structure of small coil is chatted in another patent with U-shaped pot It states).

Multiple small coils are together in series a whole overall coil of composition due to being, therefore the magnetic line of force intensity of each small coil Weak, Ying Zengjia magnetic stripe number is bonded 4-6 item under that is, each small coil, lines up circular coil magnetic stripe equidistant arrangement number and want some more, Form the most handy soft magnetic stripe of magnetic stripe under U-shaped circle.The effect of magnetic stripe is the guidance magnetic line of force and condensation of magnetic flux upwards and enhances Magnetic line of force intensity.

The present invention not only increases electromagnetic heating area, while making it should due to taking the above all scheme and measure The purposes of invention expands in many aspects such as baking (roasting) case, heater, heater and Domestic kitchen electric utensil tool.

Detailed description of the invention:

Fig. 1 is basic views of the invention；

Fig. 2 is the view that small 2 spacer ring of coil of the present invention is coiled into ring shape；

Fig. 3 is that the small coil 2 of the present invention is that oval shaped arrangements select example view；

Fig. 4 is that the small coil 2 of the present invention is that example view is selected in square arrangement；

Fig. 5 is that the small coil 2 of the present invention is that example view is selected in rectangle arrangement.

Specific embodiment:

The enameled wire Φ 0.15-0.2mm line footpath of these small coils 2 of coiling, is twisted to be wound on disk after sub-thread by 30-40 root On frame 1.Intermediate one small coil 2 is a little bigger, and the circular arrangement of its 5-6 small coil 2 of arrangement above, flanging or pressure partly line up one A great circle ring type is shown in Fig. 1；One circle arranges on plate rail 1 every the small coil 2 that a circle is coiled into a great circle ring type sees Fig. 2；It is oval It is usually that intermediate one small coil 2 is a little bigger that shape, which is arranged on plate rail 1, and the small small coil 2 in each one of both ends or centre one are big by two First three is small, and Fig. 3 is an intermediate a little bigger coil, the view of each dot coil in both ends；Square is arranged according to required heating surface size The number for determining small coil 2 is arranged on plate rail 1 with side for 3,4,5, and Fig. 4 is the view that side is 3 small coil 2；Rectangle row Be listed on plate rail 1 with a line, two rows, triple-row type the small coil 2 of arrangement, Fig. 5 be two row alignment views.The view of Fig. 1-5 is Small coil 2 several spread patterns on plate rail 1 select example diagram, practical change according to specific requirement.

The inductance of electromagnetic power output LC resonance is generally commonly used for 130-150UH, the total inductance amount after the small series connection of coil 2 This value should be equal to.If needed to be more than or less than this value depending on the application, design LC pairing can be changed, to meet actual needs.

Fitting Fig. 1 situation of magnetic stripe 3 is that intermediate a little bigger small coil 2 is 6 or so, the lower 2-3 of each small coil 2 in periphery Item, and be soft magnetic stripe 3；One circle is coiled into great circle every a circle, then is spaced substantially equidistant fitting under small coil 2 with long soft magnetic stripe 3 See Fig. 2；Magnetic stripe 3 under the small coil 2 of oval shaped arrangements is that intermediate small coil 2 is greatly 6-8 item, and the small coil 2 in both ends is small to be 4-5 Fig. 3；What square and rectangle arranged is that the number of magnetic stripe 3 is 4-6 Fig. 4, Fig. 5 under each small coil 2.

Finally say down the invention baking (roasting) case and in terms of purposes usage, coil and heated body, by line The lead of disk is drawn, unsuitable too long.Preferably, plate and coil panel space length can be for the ferromagnetic stainless steel plate of heated body apparatus 2cm or so, the reflecting plate for the magnetic line of force of resistance to heat penetration on middle interval, the heat that such coil is experienced is little, although coil is being powered There is heat when work, since coil is that have gap between dispersed arrangement and circle (circle), itself produced and institute's heat build-up amount is little, It is unlikely to reach the degree for burning enameled wire, so without fan blowing cooling, it is only necessary to have ventilation at about 1 position of coil plate rail Hole can.Heating temperature is not high as another, and temperature sensor available electron formula controls to adjust electromagnetic electronic circuit Working condition is with regard to reliable.For on family's electromagnetic cooker, then as electromagnetic oven.
