Detailed description of the invention
Fig. 1 is the schematic diagram of a kind of electromagnetic oven according to one embodiment of the invention.Refer to Fig. 1, the electromagnetic oven 100 of the present embodiment comprises closed shell 110 and thermal source 120.Front (boiler face) due to electromagnetic oven 100 is used for heating, and in order to the whole bottom and four sides emphasizing the closed shell 110 of electromagnetic oven 100 can be used to dispel the heat, is specially represented with the visual angle of the bottom of electromagnetic oven 100 by Fig. 1.
Closed shell 110 is made up of the waterproof ventilative material with microcellular structure.In the present embodiment, waterproof ventilative material comprises polymer composite.For example, polymer composite comprises the polytetrafluoroethylene (PTFE) microporous film and RIPSTOP etc. of mutual stacking lamination.
The microcellular structure size of this type of waterproof ventilative material between liquid (large-sized molecule) and gas (undersized molecule), and reaches gas and can pass through, but effect that liquid cannot pass through.For water, the gas molecule of water is scattered in space equably, when the gas molecule of water will pass through the microcellular structure of waterproof ventilative material, according to the principle of capillary moving, the microcellular structure being similar to capillary can make the gas molecule of water pass through smoothly, and reaches ventilative function.On the contrary, if under the state of liquid, aqueous water is subject to the capillary effect of the globule (namely mutual between hydrone " pull and contend with ") in the side of microcellular structure, hydrone can not depart from the opposite side that the globule penetrates into microcellular structure smoothly, therefore, waterproof ventilative material can reach the function of waterproof.
Thermal source 120 is configured in closed shell 110, and therefore, thermal source 120 is represented by dotted lines in FIG, and in the present embodiment, thermal source 120 comprises each electronic component of solenoid or electromagnetic oven inside, the discoid body that solenoid can be gone out by copper cash ring-wound.These elements operate time can produce heat, unnecessary heat energy also needs to be discharged in electromagnetic oven 100, with avoid electromagnetic oven 100 occur overheated and lost efficacy situation.
The electromagnetic oven 100 of the present embodiment forms closed shell 110 by the waterproof ventilative material with microcellular structure, air intake vent need do not set out on closed shell 110, the hot gas that extraneous cold air and self-heat power 120 send can debouch closed shell 110 by the microcellular structure of whole housing and form thermal cycle, to reach effect of heat radiation.
In other words, compared to existing electromagnetic oven, cold and hot gas goes out air intake vent to debouch housing only by ad-hoc location and size, and the electromagnetic oven 100 of the present embodiment can carry out the turnover of cooling hot gas by the microcellular structure on all surfaces of whole closed shell 110, and reaches radiating effect.Because closed shell 110 does not have opening, the closed shell 110 of electromagnetic oven 100 can have preferably structural strength.In addition, because closed shell 110 does not have opening to supply extraneous liquid (being such as water) to enter electromagnetic oven 100, and the size of the microcellular structure of itself material is also less than the size of fluid molecule, therefore, can effectively avoid electromagnetic oven 100 causes short circuit situation because of water inlet occurs.
