Described the first electromagnetic mechanism is outside equipped with the first protective jacket, and described the second electromagnetic mechanism is outside equipped with the second protective jacket, and described the 3rd electromagnetic mechanism is outside equipped with the 3rd protective jacket.
Compared with prior art, the invention has the advantages that the motor and the fan blade that have saved in traditional lampblack absorber air duct, clean oil smoke very convenient, owing to having adopted Air pressurizer, compare with traditional lampblack absorber that noise is lower, security is better, fume-exhausting efficient high.
The air that Air pressurizer will enter in the blast pipe carries out supercharging, then by the first annular chamber in the guide duct tube wall, blows to cooking fume exhaust pipe from annular air guide hole.
Air is full of in the first annular chamber of guide duct, accumulate to a certain degree and will surpass the outer normal barometric pressure of cavity, so formation wind, due to very tiny of annular air guide hole, force the air motion of the first annular chamber, constantly the air of extruding can only be gone out from tiny annular air guide hole " leakage " at last mutually, and continuous service is after a period of time, air pressure in the first annular chamber is constantly strengthened, and makes the air-flow of annular air guide hole quicker.In case the air-flow of annular air guide hole is accelerated, form the blowing effect, will cause that the interior air of cooking fume exhaust pipe is also with flowing.Air produces negative pressure in oil smoke cover, and the air of oil smoke cover below can constantly be replenished into, strengthens the air-supply effect.The stack of multichannel air-flow will form and be several times as much as the air-supply effect that blast pipe absorbs ability of air.
Airstrainer filters the air that enters before Air pressurizer.
Oil smoke in cooking fume exhaust pipe is delivered in the oil smoke passage, and the oil smoke in the oil smoke passage can flow in the second annular chamber, and due to the second annular chamber lower end closed and inclination, Residual oil can drop in oil bottle by the oil leaking hole of least significant end.
The valving that can automatically open or close, when range hood is worked, valve opening, the oil smoke in cooking fume exhaust pipe can be delivered in the oil smoke passage, after valve closing, other indoor oil smoke just can't by cooking fume exhaust pipe enter into be equipped with of the present utility model indoor.
The first sealing gasket and the second sealing gasket cooperatively interact, and can make the better tightness of valve.
Under the first coil, the second coil and tertiary coil "on" position, the upper end of the 3rd iron core is N polarity, the free end of the second iron core is N polarity, first iron core one end close with the second iron core free end is S polarity, the second iron core and the first iron core attract each other, the second iron core and the 3rd iron core repel mutually, under the effect of two external force, make valve be in open mode.Under coil no power state, valve is closed under Action of Gravity Field.
Protective jacket can prevent that oil smoke, water are to the corrosion of iron core and coil.
