The rear air inlet of air intake duct, it is described after annular coaming plate be provided with the upper discharge pipe later half air outlet, the advance air port and
The rear air inlet connects to form the air intake duct, and the first half air outlet and the later half air outlet fasten to be formed on described
Airduct, ring-type is equipped between annular side plate and rear annular coaming plate between the preceding annular side plate, preceding annular coaming plate and after described
Arc connecting portion.
A kind of Kitchen hood spiral case as described above, air inlet ring is additionally provided with the air intake duct side.
Compared with prior art, the present invention has the following advantages：
1st, this case on the outer wall of spiral case discharge pipe by setting and the integrally formed connecting plate of spiral case discharge pipe, the connection
Plate is used to spiral case body being arranged on range hood shell, and discharge pipe is divided into by connecting plate to be exposed outside range hood shell
Upper discharge pipe and the lower discharge pipe in range hood shell, the top of upper discharge pipe are provided with air outlet, and thus, spiral case only needs
It can be fixed on cigarette machine cover top plate by connecting plate, spiral case is easy for installation, and is not deposited between range hood top plate
In mating surface offset, so as to influence the discharge of oil smoke air-flow and possible oil leak situation.
2nd, annular side plate and preceding annular coaming plate before procapsid of the invention includes, back casing include rear annular side plate and
Annular coaming plate afterwards, annular arc is equipped between rear annular side plate and rear annular coaming plate between preceding annular side plate, preceding annular coaming plate
Shape connecting portion, when spiral case works, oil smoke air-flow is climbed into discharge pipe upwards along arc connecting portion, and air-out is smooth, caused
Noise is small.
