On axis.
In above-mentioned each scheme, the shape of the through-hole being arranged on matrix can be selected in the prior art arbitrary as needed
One kind, the preferably described through-hole are bending hole, circular hole and/or the strip straight hole of strip.The program can ensure Oil-gas Separation
Under effect, ensure incoming air area, obtains the balance of filter effect and suction effect.
When the through-hole is strip hole, each strip straight hole is arranged in parallel and relative to the base net in the through-hole
Central axis tilts.
When the through-hole is circular hole, each circular hole is arranged as multiple rows of in the through-hole, and each circle center line connecting for arranging circular hole is mutually flat
It goes and is tilted relative to the central axis of the base net.The structure is adapted with the rotation direction of centrifugal blower, has oil smoke into one
The water conservancy diversion and Noise Reduction of step.
Use the range hood of above-mentioned strainer used for range hood, it is characterised in that the strainer be mounted on range hood into
On air port and/or on the suction inlet of the centrifugal blower of range hood.
It is preferred that the rotation direction of each blade is consistent with the direction of rotation of the centrifugal blower, to further decrease into windage
Power promotes suction effect.
Compared with prior art, each upper and lower port of matrix connects successively in the strainer in the utility model, forms waveform knot
Structure, thereon set through-hole there is Oil-gas Separation effect, the strainer of waveform configuration to also act as the effect of water conservancy diversion and noise reduction so that
The circulation of oil smoke is more smooth, and noise is further decreased；It applies it on range hood, increases oil smoke contact oil network
Area and collision opportunity improve filter effect, and good oil gas separation effect, low noise, suction effect is good, at the same also ensure into
The air capacity for entering kitchen ventilator is not reduced, and reaches the balance of filter effect and smoke absorption effect.
