Lever 72 applies forward thrust.The position limiting structure that the pushing component 75 of the present embodiment is also used as smoke deflector 3 uses, example
Such as, under fume-exhausting operating mode, the air inlet 11 of exhaust fume collecting hood 1 is needed to remain opening state, can will be rotated by impeller 752
Bar 72 is limited in horizontal disposition, in this way, smoke deflector 3 would not move up under the effect of the wind-force of wind turbine 4.Above-mentioned promotion
Part 752 can be push-rod electric machine, and the push rod across the part of slideway 753 for push-rod electric machine.In order to make 3 oscilaltion of smoke deflector
Steadily, position-limit mechanism 7 and pushing component 75 are four groups and each corner respectively close to 1 air inlet 11 of exhaust fume collecting hood is arranged.It is above-mentioned
Position-limit mechanism 7 and pushing component 75 are when realizing sealing of the smoke deflector 3 to 1 air inlet 11 of exhaust fume collecting hood, also with finger effect,
This is because the rising of smoke deflector 3 is realized by the suction of wind turbine 4, and if fingerhold smoke deflector 3 and air inlet 11 it
Between, the negative pressure at 3 back of smoke deflector is smaller, smoke deflector 3 will not hardness rise holding finger, and when smoke deflector 3 and air inlet 11 it
Between clear when, smoke deflector 3 rises very rapidly up to close air inlet 11 under 4 suction of wind turbine, and what is generated at this time is larger
Negative pressure is conducive to be sealed air inlet 11 instead.
The operation of smoke deflector 3, wind turbine 4 and outlet housing 5 is controlled by same controller, automatically cleaning fume-exhausting in the present embodiment
The control method following steps of machine：
S1：User's selection uses program：Fume-exhausting program or self-cleaning program；
S2：If user selects fume-exhausting program, step S3 is performed；If user selects self-cleaning program, step is performed
S4；
S3：Under fume-exhausting operating mode, the controller control decline of smoke deflector 3 makes the air inlet 11 of exhaust fume collecting hood 1 unimpeded, outlet housing 5
The first air outlet 53 being connected with common flue is opened, and the second air outlet 54 is closed, and oil smoke is discharged by 4 system operation of wind turbine
In common flue；
S4：Under automatically cleaning operating mode, the first air outlet 53 that controller control outlet housing 5 is connected with common flue is closed,
Second air outlet 54 is opened, and smoke deflector 3 rises so that the air inlet 11 of exhaust fume collecting hood 1 be sealed, at this point, by liquid feed valve 100 to
Add in cleansing medium in the cavity that exhaust fume collecting hood 1 and smoke deflector 3 enclose and cleansing medium liquid level be located at strainer 2 and blow vent 10 with
On, 4 system of wind turbine is run, the air quantity of cycle is constantly poured cleansing medium generation multiphase flow and strainer 2 is rushed by 4 system of wind turbine
Brush；A period of time rear fan 4 is out of service, and cleansing medium is discharged；
Wherein, the rising of smoke deflector 3 is realized by wind turbine 4, specifically, wind turbine 4 can draw smoke deflector 3 upwards when running
Mobile, smoke deflector 3 is by pushing connecting pole 71 upwards after upward power and being moved backward with rotating bar 72, until smoke deflector 3
The air inlet 11 of exhaust fume collecting hood 1 is closed, at this point, rotating bar 72 is arranged vertically on exhaust fume collecting hood 1 and forms lock-bit, and due to
The negative pressure of larger intensity is formed in smoke machine at this time, therefore the secure seal to 1 air inlet 11 of exhaust fume collecting hood can be kept；When needs make to lead
When aerofoil 3 declines (such as S3), pushing component 75 pushes forward rotating bar 72, you can self-locking state is released, it is out of service in wind turbine 4
Under state, smoke deflector 3 declines under the effect of gravity, after declining state adjustment, can be resisted against impeller 752 horizontally disposed
Rotating bar 72 on, so as to prevent smoke deflector 3 wind turbine 4 wind-force effect under move up；
S5：Range hood is out of service.
