Abstract
The utility model relates to an electromagnet driven counter-flow prevention fume exhauster. The smoke exhaust port point of the fume exhauster is provided with a counter-flow prevention device which is driven by electromagnet, so the reliability of the counter-flow prevention of the fume exhauster is enhanced greatly, and the tightness is better. The utility model is especially suitable for the households with common smoke exhaust passages, and can effectively prevent the generation of the oil smoke counter-flow condition between the households. The utility model has the advantages of simple structure and easy manufacture.
Description
Electromagnetic Drive anti-back flow range hood of the present utility model belongs to a kind of range hood.
Usually be used in the range hood preventing that device that oil smoke flows backwards from being light and can constitute around two halves garden, the left and right sides of coaxial rotation sheet by two books.When pumping unit quit work, under the gravitational moment effect, two halves garden sheet rotated the complete garden sheet of formation and closes the range hood exhaust duct, prevented that oil smoke from flowing backwards.But after using a period of time, because greasy dirt is between the sheet of two halves garden, all have viscous effect between half garden sheet and the pipe side wall.When kitchen ventilator quits work, owing to be subjected to the effect of viscous resistance, and two halves garden sheet is made by plastics, it is not in place that weight gentlier fails to rotate or rotate, and can't close exhaust duct fully.Oil smoke in the common exhaust passage flows back in the house through kitchen ventilator like this, produces the phenomenon that oil smoke flows backwards.With should range hood during work, because the existence of viscous resistance, two halves garden sheet fails to open fully, and the exhaust duct useful area reduces, and influences smoke exhaust efficiency.
The purpose of this utility model is: propose a kind of Electromagnetic Drive anti-back flow range hood.
Electromagnetic Drive anti-back flow range hood of the present utility model is characterized in that: its Electromagnetic Drive anti-backflow device is provided with the spherical cavity flue (2) of stop (N) by pipe flue (1), and range hood smoke exhaust port (3) supports iron pipe (4), pulley (C
1), (C
2), garden sheet (7), axle (0), book iron prop (M), backguy (9) electromagnet (5), electromagnet casing (6) and constituting.Electricity of the present utility model drives the anti-back flow range hood, and (1), (2), (3) are respectively three parts of kitchen ventilator outlet pipe upper, middle and lower.Wherein (2) are spherical hollow space.N is a stop in the chamber, and AB is for can partly being made by density bigger metallic material such as copper or iron etc. around garden sheet and OA half garden that the O axle rotates.OB is made by plastics in half garden.(4) be thin iron pipe.Iron pipe both sides C
1, C
2Be the truckle that can rotate around stationary axle separately.The interior cord (9) of pipe strides across two pulleys, one end and links to each other with A, and the other end links to each other with book iron prop M.(5) be electromagnet.K is the power switch of range hood.(6) be the shell of electromagnet apparatus.When kitchen ventilator in working order time the, K switch closure, electromagnet attracts book iron prop M, and garden sheet AB clockwise rotates near the vertical position by cord (9) pulling, and this moment, outlet pipe was opened the smoke evacuation state that is in.When kitchen ventilator quit work, K switch disconnected, and the electromagnet no current passes through.OA half garden sheet is heavier in the sheet of garden, can overcome book iron prop M, and the resistance that plastics half garden OB and greasy dirt viscous etc. produce, the garden sheet of making rotate counterclockwise until B and fulcrum N and coincide, and this moment, outlet pipe was sealed, the phenomenon that oil smoke flows backwards can not occur.
Advantages such as Electromagnetic Drive anti-back flow range hood of the present utility model has simple in structurely, is easy to make, and the anti-back flow performance is good.
