At present, the common radiating mode of electromagnetic oven is taken away by the heat of the high-power components on circuit board by gilled radiator and fan, and the processing cost of gilled radiator is higher, and need the enough height of guarantee fin just can obtain satisfied radiating effect, thus, also just require that the installing space of radiator is comparatively large, cause the waste of resource to a certain extent.
Utility model content
The technical problems to be solved in the utility model is, provides the heat dissipation structure of electromagnetic oven that a kind of structure is simple, radiating effect is good, with low cost, to overcome the deficiencies in the prior art.
The utility model solves the technical scheme that its technical problem adopts: a kind of heat dissipation structure of electromagnetic oven, comprise drain pan, electromagnetic coil disk, radiator fan, control circuit board, described electromagnetic coil disk and radiator fan are arranged on drain pan, the sidewall of drain pan is provided with louvre, heat-dissipating aluminium plate is provided with between described drain pan and electromagnetic coil disk, the surface area of described heat-dissipating aluminium plate is greater than the projected area of electromagnetic coil disk, and described electromagnetic coil disk is fixed on heat-dissipating aluminium plate by securing member.
Preferably, arrange an aluminium box on described heat-dissipating aluminium plate side, described aluminium box comprises box body and lid, and described control circuit board is placed in aluminium box.
Preferably, described radiator fan is arranged in the side of aluminium box.
Compared with prior art, the beneficial effects of the utility model are:
Heat dissipation structure of electromagnetic oven of the present utility model is by being fixed on drum on the aluminium sheet larger than its area, and aluminium sheet not only shields the magnetic line of force below electromagnetic wire coil, and can also take away the heating of drum, kills two birds with one stone.
Control circuit board is fixed in aluminium box with cover, not only dust-proof, moistureproof, and splashproof is anti-tampering, can also efficiently radiates heat.
The utility model structure is simple, with low cost, is easy to manufacture.

Detailed description of the invention
Be described below in detail embodiment of the present utility model, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Be exemplary below by the embodiment be described with reference to the drawings, only for explaining the utility model, and can not be interpreted as scope of the present utility model is limited.
In description of the present utility model, it will be appreciated that, term " side ", " on ", "front", "rear", " interior ", the orientation of the instruction such as " outward " or position relationship be based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, instead of the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
See Fig. 1-4, the utility model discloses a kind of heat dissipation structure of electromagnetic oven, comprise drain pan 1, panel 2, guidance panel 3, electromagnetic coil disk 6, radiator fan 8, control circuit board 9 are installed in drain pan 1, the sidewall of drain pan is provided with louvre 5 at (at least comprising the wall being positioned at rear portion and the wall being positioned at left side or right side), heat-dissipating aluminium plate 7 is provided with between described drain pan 1 and electromagnetic coil disk 6, the surface area of described heat-dissipating aluminium plate is greater than the projected area of electromagnetic coil disk, and described electromagnetic coil disk 6 is fixed on heat-dissipating aluminium plate 7 by securing member.Electromagnetic coil disk 6 is positioned at the rear of electromagnetic oven, and front is guidance panel 3, and radiator fan 8 is then between guidance panel and electromagnetic coil disk.On current electromagnetic oven market, a lot of electromagnetic oven all from bottom air inlet, air inlet from desktop too close to, air intake has some setbacks, and hot blast also exists backflow phenomenon, and the utility model electromagnetic oven adopts air intake from the side, and air intake is more smooth and easy.
Arrange an aluminium box 4 at heat-dissipating aluminium plate 7 and electromagnetic coil disk 6 side, described aluminium box comprises box body and lid, and described control circuit board 9 is placed in aluminium box 4.Radiator fan 8 is arranged in the left side of aluminium box 4.
During electromagnetic oven work, control circuit board provides alternating current to electromagnetic coil disk, makes the iron pan the bottom of a pan heating be placed on electromagnetic oven, thus heat food.And control circuit board is arranged in aluminium box, aluminium is the extraordinary metal of a kind of thermal conductivity, and the heat that heater element produces is passed on aluminium box, then forces cooling by radiator fan, thus ensure that the operating temperature rise of control circuit board meets the requirements.Electromagnetic coil disk is placed on heat-dissipating aluminium plate, on the one hand, the magnetic line of force that maskable electromagnetic coil disk sends to drain pan, increase safety in utilization, the more important thing is, the operational heat of electromagnetic coil disk and even whole electromagnetic oven, by transmission of heat by contact, can be delivered on aluminium sheet by heat-dissipating aluminium plate rapidly, heat is taken away by convected air again, solves the heat dissipation problem of electromagnetic oven.
Moreover aluminium box is positioned at the heat-dissipating aluminium plate side of electromagnetic coil disk, the magnetic line of force of electromagnetic coil disk in this side can also be shielded.
Heat dissipation structure of electromagnetic oven of the present utility model, electromagnetic coil disk and the large heat generating components of circuit board two have independently space, and position is not overlapping, and it is thinner, more attractive in appearance that electromagnetic oven entirety can be done, and dispels the heat faster.Electromagnetic coil disk has aluminium sheet rebasing, and the area of dissipation being so equivalent to drum increases, and is more conducive to heat radiation, is risen below aluminium sheet by glue shell, solenoid panel surface, can ventilation and heat between electromagnetic coil disk and aluminium sheet, below aluminium sheet, and effect is better.Ultra-thin type electromagnetic oven in the market, does not have aluminium sheet under its electromagnetic coil disk, and when electromagnetic oven is put on metal platform, metal table top can be heated, and burns out electromagnetic oven and furniture, more may scald people.Then there is not this situation in electromagnetic oven of the present utility model.
Although illustrate and described embodiment of the present utility model; those of ordinary skill in the art is to be understood that: can carry out multiple change, amendment, replacement and modification to these embodiments when not departing from principle of the present utility model and aim; scope of the present utility model limited by claim and equivalent replacement thereof; in the improvement etc. done without creative work, all should be included within protection domain of the present utility model.
