Description
Technical field
The utility model relates to a kind of range hoods.It specifically, is to have the function of energy conservation, de-noising on fume exhauster for kitchen
Guiding device.
Background technique
It is well known that being fitted with range hood in most of kitchens to exclude the oil smoke generated during cooking.Tradition
Range hood contain an oil suction chimney, the inner end of oil suction chimney is equipped with blower, and the import of blower downward and is directed at kitchen range.
When work, the oil smoke generated in pot of being served by kitchen range is directly by after the import sucking of blower, then air outlet and suction by blower
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 blower, so that easily tying grease in blower, need often to clean range hood, not only use it is more troublesome, and
And the service life of range hood can be shortened.
To overcome problem above, the Suzhou world creates electric appliance Science and Technology Ltd. and has launched a collection of oil smoke and blower phase to market
Isolated range hood.This range hood includes blower and guiding device, guiding device therein contain square box, on lead
Flow cartridge and lower guide shell, upper guide shell internal diameter are greater 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 Kong Sizhou.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 protruded into lower guide shell upper end
It is interior, so that there are the spacing that oil smoke passes through between the upper end outer circle of lower guide shell and the lower end inner circle of upper guide shell.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 blower, 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 being then passed through between lower guide shell upper end and upper guide shell lower end, which enters, above to be led
While flow cartridge, the oil smoke that kitchen range generate successively is sucked into lower guide shell and upper guide shell, finally, being discharged from upper guide shell upper end
It is outdoor.This range hood, oil smoke are mutually separated with blower, not only be can avoid blower fouling condition and are occurred, 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 and 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 can not only be generated 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, fume exhaust low efficiency.
Utility model content
Problem to be solved in the utility model is to provide a kind of range hood guiding device.It, can using this guiding device
The operation noise and energy consumption of range hood are reduced, fume-exhausting efficiency is improved.
The above problem to be solved in the utility model is realized by the following technical scheme:
The range hood guiding device of the utility model includes upper guide shell and lower guide shell, and lower guide shell outer diameter is less than upper
Guide shell internal diameter, lower guide shell upper end, which is protruded into guide shell lower end and between the two, spacing.There is annular wind on the outside of lower guide shell
There are air inlet in road, annular passage side, its main feature is that the annular passage gradually tilts upwards from air inlet side to its opposite side
And by being connected after the spacing with upper water conservancy diversion tube inner chamber.
Wherein, the annular passage includes two sides between the vertical both sides of air inlet and upper guide shell two 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 on deflector, lower guide shell is worn
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 lower than its back, on its surface and lower guide shell
Inclination angle is formed between lower end surface.
The inclination angle is greater than 90 degree, and is less than 180 degree.
Preferred inclination angle is 120 ~ 160 degree.
Optimal inclination angle is 150 degree.
Further improvement of the utility model scheme is that the air inlet has first flange.
Further improvement of the utility model scheme is that the lower end of lower guide shell has second flange, is put down locating for second flange
Face is vertical with plane locating for first flange.
The further improvement project of the utility model is, there is a second flange in the lower end of lower guide shell, locating for second flange
Plane is vertical with plane locating for first flange.
It can be found out by above scheme, since the annular passage gradually tilts simultaneously upwards from air inlet side to its opposite side
By being connected after the spacing with upper water conservancy diversion tube inner chamber.So that entering the sky with certain pressure of annular passage from air inlet
Gas is above led along gradually 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 hits 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.
Detailed description of the invention
