Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
Embodiment one
Seeing Fig. 1～Fig. 6, a kind of range hood, including the 1st, exhaust fume collecting hood is arranged on casing 2 above exhaust fume collecting hood 1, casing 2
It is inside provided with blower fan 3.Offering air inlet 11 on exhaust fume collecting hood 1, thus, oil smoke can be aspirated through air intake by the blower fan 3 in casing 2
Mouth 11 is discharged into common flue after entering into casing 2.The bottom rear of exhaust fume collecting hood 1 is provided with lubricating cup 6.
Casing 2 includes left side wall the 21st, right side wall the 22nd, front side wall 23 and rear wall 24.It is provided with by up on left side wall 21
Under gradually to the left sidewall 21 tilt the first silencing apparatus 71, right side wall 22 is provided with from top to bottom gradually to the right sidewall 22 incline
The second oblique silencing apparatus 72, front side wall 23 is provided with the 3rd silencing apparatus that from top to bottom gradually sidewall 23 tilts forward
73, rear wall 24 is provided with the 4th silencing apparatus 74 from top to bottom gradually tilting to rear wall 24.Aforementioned four is eliminated the noise and is filled
Below blower fan 3, the runner of the cavity formation oil smoke air-flow between silencing apparatus.Above-mentioned each silencing apparatus can use conventional
Orifice plate combine the structure of acoustical cotton.
In the present embodiment, blower fan 3 uses ternary blower fan, can use prior art, such as Application No.
201310418009.X Chinese patent disclosed in.Alternatively, blower fan 3 also can use centrifugal blower.Interior, the position of casing 2
The lower section of blower fan 3 is provided with filter screen 4, filter screen 4 offers multiple mesh 41.Filter screen 4 at least has concave up in centre
Recess 42, in the present embodiment, recess 42 is taper type, thus can preferably oil strain with hold together cigarette.The shape of mesh 41 is permissible
For regular hexagon, circle, square, rectangle, strip etc..
The lower section of casing 2 is provided with oil drain pan 5, and it is perpendicular that the geometric center of filter screen 4 and the geometric center of blower fan 3 are positioned at same
On straight line, and the bottom of filter screen 4 is formed with first silencing apparatus 71 medial surface (face towards in runner) in left side in casing 2
Included angle 1, the bottom of filter screen 4 forms included angle 2, the bottom of filter screen 4 with second silencing apparatus 72 medial surface on right side in casing 2
Form included angle 3, the bottom of filter screen 4 and the 4th of rear side in casing 2 with the 3rd silencing apparatus 73 medial surface of front side in casing 2
Silencing apparatus 74 medial surface forms included angle 4, i.e. the bottom of filter screen 4 is inclined with each side of casing 2 inner flow passage, and φ the 1st, φ is the 2nd,
φ the 3rd, φ 4 preferably 5 °～80 °, the oil contributing under blower fan 3 is got rid of by filter screen 4 imports to oil drain pan 5.
Oil drain pan 5 includes ring-type lateral wall the 51st, madial wall 52 and is connected to lateral wall 51 and the bottom of madial wall 52
