Embodiment 1
To shown in Figure 3, it is the specific embodiment 1 of electromagnetic oven of the present invention, comprises shell 1, is arranged on the air port on the shell 1 as Fig. 1.Described air port comprises slew page, slew page support and electric device.The slew page support is rectangular, and slew page is installed on the slew page support, the transmission device that it comprises some slew page sheets, is located at a fixed leg of slew page sheet one end and is located at the slew page sheet other end.Described air port comprises air inlet 2 and air outlet 3.
Electromagnetic oven shell 1 is provided with a projection 11 in air inlet 2 one sides.These projection 11 inner hollow, it has spring fixed block 113, resettlement section 115 and perforate 117.First spring, 232 other ends buckle on spring fixed block 113.First electromagnet 233 is installed in the resettlement section 115.Fixed part 2342 passes from described perforate 117.Described first erection column 2233 is installed in the installing hole 2341.
Air intake slew page support 21 is fixed on the electromagnetic oven shell 1 by screw or other modes.
Air outlet 3 comprises air-out slew page 32, air-out slew page support 31 and air outlet electric device 33.Air-out slew page support 31 is rectangular, and its upper and lower dual-side is respectively equipped with second fixing hole 311.Air-out slew page 32 is installed on the air-out slew page support 31, the air outlet transmission device 323 that it comprises some air-out slew page sheets 321, is located at the 3rd fixed leg 322 of air-out slew page sheet 321 1 ends and is located at air-out slew page sheet 321 other ends.Described air outlet transmission device 323 comprises the 4th fixed leg 3231, extends and perpendicular second drive link 3232 and from second drive link, 3232 terminal extensions and the second perpendicular erection columns 3233 from the 4th fixed leg 3231 is terminal.The 3rd fixed leg 322 and the 4th fixed leg 3231 pass second fixing hole 311 of air-out slew page support 31 both sides respectively, and air-out slew page sheet 321 is installed on the air-out slew page support 31.It comprises second permanent magnet 331, second spring 332, second electromagnet 333 and second gear frame 334 air outlet electric device 33.Described second gear frame 334 comprises stem and from the upwardly extending holding parts 3342 that is used for fixing permanent magnet 331 of stem.Described stem is provided with second installing hole 3341.Holding parts 3,342 one ends are fixed second permanent magnet 331, can fasten with glue or interference engagement is fixed, and holding parts 3342 other ends are connected with second spring, 332 1 ends.Electromagnetic oven shell 1 is provided with the fixture 335 that is used for fixing second electromagnet 333.Second spring, 332 other ends are fixed on the fixture 335.Certainly, also can not need air-out slew page support 31 in other embodiments, directly air-out slew page 32 is installed on the shell 1.
Air-out slew page sheet 321 front ends are provided with hyoplastron 3211, root jagged 3212.When air-out slew page sheet 321 closures, hyoplastron 3211 fastens and is against breach 3212 places.So, make air-out slew page sheet 321 seamless fully each other when closure, and when opening, do not have bigger friction each other, make things convenient for air-out slew page sheet 321 to open flexibly.Certainly, air intake slew page sheet 221 also can be made according to the design of air-out slew page sheet 321.
When electromagnetic oven is started working, first electromagnet 233 and second electromagnet 333 are under galvanic effect, produce magnetic, first permanent magnet 231 and second permanent magnet 331 that absorption is corresponding, first permanent magnet 231 and second permanent magnet 331 drive first gear frame 234 and second gear frame 334 respectively, and first gear frame 234 and 334 linear movements of second gear frame drive the about an angle of 90 degrees degree of air-out slew page sheet 321 rotations, thereby air intake slew page sheet 221 and air-out slew page sheet 321 are opened, electromagnetic oven is in ventilation state, and air can freely circulate.When electromagnetic oven is worked, first electromagnet, 233 absorption, first permanent magnet 231, first spring 232 is in the tensile deformation state, produces certain deformation power, when electromagnetic oven quits work, 233 demagnetizations of first electromagnet, suction reduces or becomes zero between itself and first permanent magnet 231, under the 232 restoring force effects of first spring, promotes 234 motions of first gear frame, drive air intake slew page sheet 221 and rotate, thereby air intake slew page sheet 221 is closed.Simultaneously, when electromagnetic oven was worked, second electromagnet, 333 absorption, second permanent magnet, 331, the second springs 332 were in the compressive deformation state, produce certain deformation power, when electromagnetic oven quits work, 333 demagnetizations of second electromagnet, suction reduces or becomes zero between itself and second permanent magnet 331, under the 232 restoring force effects of second spring, promote 334 motions of second gear frame, drive air-out slew page sheet 321 and rotate, thereby air-out slew page sheet 321 is closed.
As shown in the present embodiment, air inlet 2 and air outlet 3 all can be designed to said structure generally speaking, but in other embodiments, also can only air outlet 3 be made said structure, and corresponding existing fixed cell structure that air inlet 2 is made; Perhaps only air inlet 2 is made said structure, and corresponding air outlet 3 is made the existing fixed cell structure.
To shown in Figure 7, it is the specific embodiment 2 of electromagnetic oven of the present invention as Fig. 4, and wherein Fig. 4 and Fig. 5 are the schematic diagram of second embodiment of the invention air-out slew page sheet 321 closures, the schematic diagram that Fig. 6 and Fig. 7 open for second embodiment of the invention air-out slew page sheet 321.As another embodiment of the present invention, the difference of itself and embodiment one is that the open and close of described air-out slew page sheet 321 realized by the gear 3234 and second the cooperating of gear frame 334.In the present embodiment, described second gear frame 334 is the tooth bar form with gear 3234 corresponding matching.The open and close of described air intake slew page sheet also can realize by said gear and cooperating of gear frame structure.
When electromagnetic oven is started working, second electromagnet 333 is under galvanic effect, produce magnetic, corresponding second permanent magnet, 331, the second permanent magnets 331 of absorption drive second gear frame 334, and second gear frame, 334 linear movement driven gears 3234 rotate, and then drive air-out slew page sheet 321 rotates about an angle of 90 degrees degree, thereby air-out slew page sheet 321 is opened, and electromagnetic oven is in ventilation state, and air can freely circulate.When electromagnetic oven is worked, second electromagnet, 333 absorption, second permanent magnet, 331, the second springs 332 are in the compressive deformation state, produce certain deformation power, when electromagnetic oven quits work, suction reduces or becomes zero between 333 demagnetizations of second electromagnet, itself and second permanent magnet 331, under the 232 restoring force effects of second spring, promote 334 motions of second gear frame, driven gear 3234 rotates, and then drives 321 rotations of air-out slew page sheet, thereby air-out slew page sheet 321 is closed.
The present invention can open it because air inlet 2 or air outlet 3 or the two are made electronic mode automatically when electromagnetic oven is worked, and when the electromagnetic oven deenergization auto-closing.The present invention can effectively prevent electromagnetic oven the entering of insect under off-position, and lower and to take the electromagnetic oven inner space less with respect to the prior art cost.Prior art is simple in structure relatively, does not need original grid, utilizes the two states of slew page to realize opening, closing.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the present invention, and be not as limitation of the invention, as long as in connotation scope of the present invention, all will drop in claims scope of the present invention variation, the modification of the above embodiment.
