Abstract
The invention relates to an induction cooker wire coil which can reduce the heat dissipation load in an induction cooker. The induction cooker wire coil comprises a wire coil bracket, a magnetic stripe and a coil which are sequentially installed from bottom to top, wherein a cover plate is arranged on the coil, and the wire coil bracket forms an integral plate. The cover plate is arranged on the coil, and the cover plate is matched with the integral plate type wire coil bracket to clamp the coil so as to form a seal wire coil structure; the heat generated by the wire coil can not outwards disseminate in the process of working, and the heat of a cooker on the surface of the induction cooker is blocked to spread to the wire coil, thereby greatly reducing the heat emission of the induction cooker in the process of use; a fan with low power can be adopted, the noise generated by the fan can be reduced, and the heat efficiency can be also improved.
Description
(1) technical field
The present invention relates to the parts of electromagnetic oven, be specially a kind of electromagnetic oven wire coil.
(2) background technology
Electromagnetic oven wire coil is a critical component in the electromagnetic oven, produce serial or parallel connection resonance by drum and miscellaneous part during electromagnetic oven work, produce the alternating magnetic field of a 20KHZ～30KHZ above drum, when cooking pot tool placed this magnetic field, pan can be responded to heating voluntarily.
Generally all about 1000W～3000W, the average current that flows through in drum has tens amperes to the power of family expenses electromagnetic oven, and so big electric current makes drum become the pyrotoxin of an inner maximum in the electromagnetic oven use.When electromagnetic oven adopted ordinary pan, pot bottom was 100 ℃～200 ℃ high temperature, and the pot bottom area is generally 300 square centimeters, and when the material of electromagnetic oven panel was glass, pottery, thickness was 0.4 centimetre.When panel downside temperature is 80 ℃,, then import the about 120W of heat flow of electromagnetic oven inside into by panel if the pot bottom temperature is 100 ℃; If the pot bottom temperature is 200 ℃, then import the about 720W of heat flow of electromagnetic oven inside into by panel.In common electromagnetic oven, these heats all will distribute to the outside by fan.
In order to reduce the drum temperature, existing method is the power that improves constantly electromagnetic oven internal heat dissipating fan, the heat that drum is produced is discharged to the machine outside as soon as possible, thereby reduce the temperature of drum, minimizing causes the influence to miscellaneous part such as printed circuit board (PCB) (PCB), plastic casing etc. because of the drum temperature is too high.But under the constant prerequisite of other condition, the power of fan is big more, wind speed is fast more, and then the heat loss through convection coefficient is big more.Make reality more much bigger than above-mentioned static heat output thus by the heat that panel imports electromagnetic oven inside into.In fact, generally speaking, the heat that imports into by panel is also bigger than the caloric value of circuit own.And these heats all were the efficient heat of electromagnetism heating originally.Blow a cold wind over to panel with fan, equal to blow a cold wind over to pot bottom indirectly, this is vicious circle.
In embedded electromagnetic oven field, electromagnetic oven is done as a whole being embedded in the cabinet in addition, has only the electromagnetic oven boiler face to expose on the cabinet table top, and is easy to use, easy to clean, overall appearance.It is limited that but the cabinet of sealing is left the heat-dissipating space of electromagnetic oven for; if still according to the Bobbin structure and the radiating mode of original desk-top electromagnetic oven; the cabinet internal temperature will be more and more higher, thereby cause environment too high and cause electromagnetic oven over-heat inside protection, the service life of having reduced electromagnetic oven.
(3) summary of the invention
At the problems referred to above, the invention provides a kind of electromagnetic oven wire coil, it can significantly reduce electromagnetic oven internal heat dissipating load.
Its technical scheme is such: it comprises drum support, magnetic stripe and the coil of order installation from top to bottom, and it is characterized in that: be provided with cover plate above the described coil, described drum support is an integral slab.
The further technical scheme of the present invention is:
The material of described drum support adopts high-temperature resistant plastics or heatproof epoxy plate; Described cover plate adopts the partiting thermal insulation material; Be provided with insulating trip between described coil and the described magnetic stripe; Described insulating trip adopts the partiting thermal insulation material.
The present invention is provided with cover plate on coil, cover plate cooperates with whole board-like drum support coil is clipped in the middle, and constitutes a kind of Bobbin structure of sealing; In the course of the work, the heat that drum produces does not disseminate outward, simultaneously also stoped the heat of boiler face pan to pass to drum, make electromagnetic oven in use, the heating of self significantly reduces, can adopt lower powered fan, not only fan noise can be reduced, but also can improve the thermal efficiency.
(4) description of drawings
Fig. 1 is the decomposition texture schematic diagram of first kind of embodiment of the present invention;
Fig. 2 is the decomposition texture schematic diagram of second kind of embodiment of the present invention.
(5) specific embodiment
As shown in Figure 1 and Figure 2, the present invention is a kind of electromagnetic oven wire coil, and it comprises drum support 5, magnetic stripe 4 and the coil 2 of order installation from top to bottom.Magnetic stripe 4 is a manganese-zinc ferrite, has many, in order to the magnetic field of shielded coil 2 belows.Improvements of the present invention are: be provided with cover plate 1 on coil 2, drum support 5 adopts integral slab, has cancelled the louvre on the conventional electromagnetic oven wire coil support.Cover plate 1 cooperates with whole board-like drum support 5 coil 2 is clipped in the middle, and constitutes a kind of Bobbin structure of sealing.In the course of the work, the heat that drum produces does not disseminate outward, simultaneously also stoped the heat of boiler face pan to pass to drum, make electromagnetic oven in use, the heating of self significantly reduces, can adopt lower powered fan, not only fan noise can be reduced, but also can improve the thermal efficiency.
In order to improve the heat-proof quality of drum, the material of drum support 5 adopts high-temperature resistant plastics or heatproof epoxy plate, and cover plate 1 adopts partiting thermal insulation materials such as asbestos.
In order further to improve the airtight performance of coil 2, between coil 2 and magnetic stripe 4, can also be provided with insulating trip 3.Insulating trip also adopts the partiting thermal insulation material to make.
Shown in Figure 1 is first kind of embodiment of the present invention, and it adopts the coil 2 of a circle, and the shape of corresponding cover plate 1, insulating trip 3 and drum support 5 also is circular, and magnetic stripe 4 is a plurality of rectangular strips of rounded array.
Shown in Figure 2 is second kind of embodiment of the present invention, different with first kind of embodiment is, coil 2 wherein is to be in series by four coils, and corresponding cover plate 1, insulating trip 3 and drum support 5 be shaped as square, magnetic stripe 4 is four polygon mats of rectangular array.
Embodiments of the present invention are not limited to above-mentioned two kinds of embodiment, and other embodiment can also be arranged, such as: coil 2 can adopt a plurality of coils from parallel connection of coils modes; Coil 2 can also adopt square structure; Coil 2 can adopt the multiply structures of copper lines, also can adopt square structures of copper lines.
After the present invention adopts airtight drum, the heat flow of importing electromagnetic oven inside from panel into can be reduced to originally 1/10th, can significantly reduce the heat radiation load of electromagnetic oven inside.
When the present invention is used for embedded electromagnetic oven, can avoid the influence of confined space, improve the service life of electromagnetic oven electromagnetic oven heat radiation.
