Specific embodiment
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, and for explaining only the invention, and is not considered as limiting the invention.
It is understood that the sound quality of kitchen ventilator in a state of use is the sound that user can experience conscientiously, oil
The key problem that the needs of smoke machine overcome is in addition to noise reduction also needs to reduce sound quality.Side-suction type range hood due to its installation site compared with
It is low, blower position in side-suction type range hood and human ear more closely, therefore under same use state, side-suction type range hood
Loudness is much greater relative to top suction type kitchen ventilator.
In the related art, top suction type kitchen ventilator carries out drainage noise reduction and suction to top suction type kitchen ventilator by diversion component
Noise is received, runner from the bottom to top gradually becomes smaller, and draining by diversion component improves air flowing, and diversion component cooperates acoustical cotton
Sound-absorbing effect is realized, but due to the obliquity structure of diversion component, so that the sound that spreads out of of the air inlet of blower is by some quilt
It is reflected towards lower air inlet propagation, since the lower air inlet of top suction type kitchen ventilator is close to human ear, i.e., by a part of sound reflection to people
At ear, the loudness of kitchen ventilator is increased.
Kitchen ventilator 100 according to an embodiment of the present invention is described below with reference to Fig. 1-Fig. 6, the embodiment of the present invention is with side-suction type oil
It is illustrated for smoke machine 100.
