The operation principle of the range hood is as follows：
As shown in figure 4, when kitchen range or so are cooked simultaneously, the left wind turbine 2 and right wind turbine 3 of the range hood start, outlet air
Cover partition board 7 is vertically arranged at the centre of outlet housing 4, and outlet housing 4 is divided into left chamber 41 and right chamber 42 two by outlet housing partition board 7
Independent chamber, at this point, left deflector 5 and right deflector 6 are in reset state, i.e., left deflector 5 and right deflector 6 are in
On water conservancy diversion position, left fan outlet 21 and right fan outlet 31 are opened, left chamber of 2 air-flow of left wind turbine through outlet housing 4
Room 41 is discharged, and right chamber 42 of 3 air-flow of right wind turbine through outlet housing 4 is discharged, and the air-flow of left chamber 41 and right chamber 42 is mutual indepedent
And do not interfere with each other, to effectively reduce the collision of two strands of air-flows, vortex is eliminated, reduces aerodynamic noise.
As shown in figure 5, when kitchen range only left side culinary art when, left wind turbine 2 start and right wind turbine 3 does not start, outlet housing partition board 7 to
Right deflection completely, left deflector 5 still in water conservancy diversion position and right deflector 6 upward deflects and closes right fan outlet 31, this
When, 2 air-flow of left wind turbine is discharged through the left chamber 41 of left fan outlet 21 and outlet housing 4, to the right due to the deflection of outlet housing partition board 7
Side, left side volume become larger, and discharge area increases, identical in flow according to fluid continuity equation, discharge area
Increase, fluid velocity reduce, dynamic pressure reduce, aerodynamic noise reduce, in addition, by according to bernoulli principle it is found that in gas total head
Under the premise of certain, power reduction can be such that static pressure increases.In addition, in the state of the deflection completely to the right of outlet housing partition board 7, outlet air
Closed right noise reduction cavity 92 is enclosed between cover partition board 7, right deflector 6 and outlet housing 4 jointly, due in outlet housing partition board 7
On be provided with noise reduction hole 71, therefore, right noise reduction cavity 92 is made to form Helmholz resonance chamber, according to Helmholz resonance principle of noise reduction,
Noise when left wind turbine 2 works can be further decreased.
As shown in fig. 6, kitchen range only right side culinary art when, right wind turbine 3 start and left wind turbine 2 does not start, outlet housing partition board 7 is to the left
Completely deflection, right deflector 6 still in water conservancy diversion position and left deflector 5 upward deflects and closes left fan outlet 21, at this point,
3 air-flow of right wind turbine is discharged through the right chamber 42 of right fan outlet 31 and outlet housing 4.In addition, complete to the left in outlet housing partition board 7
In the state of deflection, closed left noise reduction cavity 91 is enclosed between outlet housing partition board 7, left deflector 5 and outlet housing 4 jointly,
Due to being provided with noise reduction hole 71 on outlet housing partition board 7, so that left noise reduction cavity 91 is formed Helmholz resonance chamber, according to conspicuous nurse
