Description
Technical field
The present invention relates to a kind of range hoods.Specifically, it is that there is energy saving, de-noising function lead on fume exhauster for kitchen
Flow device.
Background technology
It is well known that exclude the oil smoke generated during cooking, range hood is fitted in most of kitchens.Tradition
Range hood contain there are one oil suction chimney, the inner end of oil suction chimney is equipped with wind turbine, wind turbine into mouth down and be directed at kitchen range.
When work, after the oil smoke generated in pot of being served by kitchen range is directly sucked by the import of wind turbine, then the air outlet by wind turbine and suction
The discharge of oil smoke cylinder is outdoor.Although the oil smoke in kitchen can be excluded using this range hood, since oil smoke is directly inhaled into
In wind turbine so that easily tie grease in wind turbine, need often to clean range hood, not only use it is cumbersome, and
And the service life of range hood can be shortened.
To overcome problem above, Suzhou world wound electric appliance Science and Technology Ltd. to launch a collection of oil smoke and wind turbine phase to market
The range hood of separation.This range hood includes wind turbine and guiding device, guiding device therein contain square box, on lead
Flow cartridge and lower guide shell, upper guide shell internal diameter are more than lower guide shell outer diameter.It is machined with respectively on the top plate and bottom plate of square box
Upper hole and lower opening, upper guide shell are on the top plate of square box, and upper guide shell lower end is connected to hole surrounding.It is led under described
Flow cartridge is in square box, and lower guide shell lower end links together with lower opening surrounding, and lower guide shell is stretched into lower guide shell upper end
It is interior so that between the upper end outer circle of lower guide shell and the lower end inner circle of upper guide shell there are oil smoke by spacing.Square box
It is machined with air inlet on one side wall, under installation condition, the air inlet is connected with the air outlet of wind turbine, the lower opening and kitchen range
It is corresponding.When work, room air passes through the air inlet and square box on fan outlet, square box under fan action
After annular passage between lower guide shell surrounding, the spacing entrance being then passed through between lower guide shell upper end and upper guide shell lower end is above led
While flow cartridge, the oil smoke that kitchen range generate is sucked into lower guide shell and upper guide shell successively, finally, is discharged from upper guide shell upper end
It is outdoor.This range hood, oil smoke are separated with wind turbine, not only can avoid wind turbine fouling condition and occur, reduce to range hood
Cleaning, and the service life of range hood can be extended.But since the inner cavity of square box is still square so that from air inlet
Mouth enters the air with certain pressure in square box first with after the shock of the rear wall of square box, transfers and passes through upwards
After descending the spacing between guide shell upper end and upper guide shell lower end afterwards, enter back into guide shell.Wherein, air and square box
Rear wall is hit, and not only be will produce noise, can also be wasted unnecessary electric energy, therefore, using the fume exhaust of this guiding device
Machine, operation noise is big, big energy-consuming, and fume exhaust efficiency is low.
Invention content
The problem to be solved in the present invention is to provide a kind of range hood guiding device.Using this guiding device, can reduce
The operation noise and energy consumption of range hood improve fume-exhausting efficiency.
The invention solves the above problem realized by following technical scheme：
The range hood guiding device of the present invention includes upper guide shell and lower guide shell, and lower guide shell outer diameter is less than in upper guide shell
Diameter, lower guide shell upper end, which is stretched into guide shell lower end and between the two, spacing.There are annular passage, annular wind on the outside of lower guide shell
There is air inlet in road side, its main feature is that the annular passage gradually tilts from air inlet side to its offside and upwards by described
It is connected with upper water conservancy diversion tube inner chamber after spacing.
Wherein, the annular passage includes two sides between the vertical both sides of air inlet and upper guide shell both sides lower end
Plate, two side plates are approximate right angle triangle, one straight flange vertical edge corresponding to air inlet is linked together, another is straight
Top plate is connected between side.Top plate front is straight flange and to be linked together with the top of air inlet, top plate back be arc-shaped side and with above lead
Outer circle is linked together on front side of the lower end of flow cartridge.There is deflector between the bevel edge of two side plates, there is through-hole, lower guide shell to wear on deflector
Enter in the through-hole.Between the right and left of deflector and corresponding side plate bevel edge, deflector back and upper guide shell it is following between, water conservancy diversion
It is linked together between plate back and upper guide shell back so that deflector front is less than its back, on its surface and lower guide shell
Inclination angle is formed between lower face.
The inclination angle is more than 90 degree, and is less than 180 degree.
Preferred inclination angle is 120 ~ 160 degree.
Best inclination angle is 150 degree.
Further improvement of the present invention scheme is that the air inlet has first flange.
Further improvement of the present invention scheme is, there is a second flange in the lower end of lower guide shell, plane residing for second flange with
Plane residing for first flange is vertical.
The further improvement project of the present invention is, there is a second flange in the lower end of lower guide shell, plane residing for second flange
It is vertical with plane residing for first flange.
It can be found out by said program, since the annular passage gradually tilts simultaneously upwards from air inlet side to its offside
By being connected with upper water conservancy diversion tube inner chamber after the spacing.So that entering the sky with certain pressure of annular passage from air inlet
Gas is above led along gradual acclivitous air duct directly through entering after the spacing between lower guide shell upper end and upper guide shell lower end
Flow cartridge avoids and is hit with the rear wall of square box, thus greatly reduce the operation of kitchen hood compared with the background art
Noise and energy consumption improve fume exhaust efficiency.
