As depicted in figs. 1 and 2, the kitchen ventilator check-valves in the present embodiment is mounted in kitchen ventilator main body 10, mainly includes
Valve seat 20 and baffle component 30.
There is the exhaust passage 21 passed through for oil smoke in kitchen ventilator main body 10 on valve seat 20, one end of exhaust passage 21 with
Blower fan system connection in kitchen ventilator, the other end are connected to the chimney outside kitchen ventilator, the oil smoke discharge that can aspirate blower fan system
Into chimney.Baffle component 30 is mounted in the exhaust passage 21 on valve seat 20, for preventing the oil smoke by exhaust passage 21
Enter in kitchen ventilator main body 10 from being flow backwards in chimney, wherein the baffle component 30 in the present embodiment includes baffle, and is mounted on
On baffle, for carrying out the sound-absorbing structure of sound-absorbing to the cooking fume stream by exhaust passage 21, by kitchen ventilator valve seat 20
Baffle on sound-absorbing structure is set, absorbed, and then be not necessarily to by the noise that sound-absorbing structure generates blower fan system in kitchen ventilator
The structure for improving blower fan system in kitchen ventilator can further decrease the noise of blower fan system generation.
As shown in Figures 3 to 5, the baffle component 30 in the present embodiment is specifically mounted on valve seat 20 close to the one of chimney
End has cooking fume to circulate out-of-date towards the direction of chimney opening exhaust passage 21 in blower fan system, oil-free in blower fan system
Exhaust passage 21 is closed when cigarette, is prevented the oil smoke in chimney from flowing backwards and is entered in kitchen ventilator.
Baffle component 30 includes mainly bracket 34, is fixed on valve seat 20；Shaft 33 is mounted on bracket 34；Wherein, it keeps off
Piece is mounted in shaft 33, first flap 31 and second flap 32 including that can block exhaust passage 21 jointly, first flap 31
With second flap 32 can positive air-flow by when rotation erect, and then can reduce the space occupied when baffle erects, just
It is fully opened in by baffle.It is specifically also equipped with the torsional spring 35 as return unit in shaft 33, stops oil smoke in blower fan system
After the conveying of air-flow, first flap 31 and second flap 32 are resetted under the elastic acting force of torsional spring 35 in tiled state, are made
Exhaust passage 21 is obtained to close.
With further reference to Fig. 2, the sound-absorbing structure in the present embodiment includes the sound-absorption hole 37 being molded on baffle, for blower
The noise of oil smoke air-flow in system, sound wave can convert thermal energy for sound in 37 internal reflection of sound-absorption hole when by check-valves, into
And reduce the noise of range hood fan system.
This implementation sound-absorption hole 37 is integrally formed on baffle, and then can be dropped while guaranteeing 37 sound-absorbing effect of sound-absorption hole
The manufacturing cost of low check-valves.Sound-absorption hole 37 can be the rules such as circular hole, square hole, elliptical aperture or diamond hole in practice

His unlimited form can play the non-sticky oil coating of the effect of oily dirt free, can reduce the greasy dirt being stained on baffle in this way, improve baffle
Using effect.
In a variant embodiment, the number of plies of baffle is such as two layers of multilayer, between the sound-absorption hole 37 on adjacent baffle
Setting is mutually staggered, and then the propagation path of noise can be lengthened, the effect for reducing the noise of blower fan system is more preferable.Multilayer baffle
Between fastening can be used, positioning the fixed forms such as separates and is fixed.
Preferably, the gap between multilayer baffle is easy to cause sound wave not transmit in 0mm between 1mm, gap is too small
Space, the sound-absorbing effect of the sound-absorption hole 37 of the excessive then multilayer in gap is bad.
With further reference to Fig. 2, the sound-absorbing structure in the present embodiment further includes the sound-absorbing pad 36 being arranged on baffle, sound-absorbing pad
36 are made using sound-absorbing material for example, by using materials such as acoustical cotton, polynary fat vacuole foam, glass fibre or foamed plastics, and sound-absorbing is utilized
Characteristic possessed by pad 36 itself can realize the reduction of noise in blower fan system.
Preferably, it is provided with sound-absorption hole 37 and sound-absorbing pad 36 simultaneously on the baffle in the present embodiment, is guaranteeing to reduce enough
While noise result, can also play the role of one when baffle is closed prevents oil smoke air-flow from flowing backwards, and ensure that kitchen ventilator
In check-valves can preferably play the role of preventing air-flow from flowing backwards.
Specifically, the sound-absorbing pad 36 in the present embodiment is fixed on baffle by way of stickup, can also pass through detent
Mode be fixed on baffle.
The scheme of first flap 31 and second flap 32 is used for gasket, the preferably thickness of sound-absorbing pad 36 is less than standing
Gap between first flap 31 and second flap 32 ensure that first flap 31 and second flap 32 at work can be normal
It opens on ground.
The present embodiment also provides a kind of kitchen ventilator, including kitchen ventilator main body 10 and kitchen ventilator check-valves, kitchen ventilator check-valves
Kitchen ventilator for kitchen ventilator check-valves as described above, and then advantage possessed by above-mentioned kitchen ventilator check-valves, in the present embodiment
Also should have, details are not described herein.
Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or
It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or
