Specific embodiment
This utility model is described in further detail below in conjunction with accompanying drawing embodiment.
Referring to Fig. 1～Fig. 3, a kind of pair of air-inlet range hood, including exhaust fume collecting hood 1, the fan shroud being arranged on above exhaust fume collecting hood 1
2nd, and the blower fan system 3 that is arranged in fan shroud 2.
Air inlet 11 is offered on exhaust fume collecting hood 1, below exhaust fume collecting hood 1, with 11 corresponding position of air inlet, smoke deflector is provided with
4, smoke deflector 4 can be flat board, or the Application No. 201310627395.3 of the plate of concave shape, such as the applicant
Diffusion drain smoke control plate disclosed in Chinese patent.
The usual range hood of this use smoke deflector 4, only the surrounding edge below the exhaust fume collecting hood 1 there is negative pressuren zone, by
This can substantially reduce smoke absorption effect.For this purpose, in this utility model, opening is offered on smoke deflector 4 so as to form fume-exhausting
The interior air inlet 41 of machine, and the gap between 4 edge of smoke deflector and exhaust fume collecting hood 1 is then formed as the external air inlet of the range hood of annular
Mouth 42, constitutes the range hood with double air inlets.Thus can ensure all exist immediately below exhaust fume collecting hood 1 and near the position at edge
Negative pressuren zone so that range hood has the external air inlet port 42 of middle interior air inlet 41 and exterior annular, and interior air inlet 41 is in side
Shape, its area are preferably not less than the 25% of 4 entirety of smoke deflector, so as to ensure certain intake.Interior air inlet 41 ensures collection
The negative pressuren zone concentrated below petticoat pipe 1, most of lampblack absorber enter range hood from interior air inlet 41；External air inlet port 42 causes negative pressure
Area extends out, the oil smoke that do not capture of residue, is entered range hood by external air inlet port 42 escaping into around smoke deflector 4, so as to big
Improve greatly the smoke absorption effect of range hood.
In this utility model, blower fan system 3 has two air inlets, enters in fan shroud 2 from interior air inlet 41
Oil smoke and the oil smoke entered in fan shroud 2 from external air inlet port 42, enter into blower fan from the various inlet mouth of blower fan system 3 respectively
It is then exhausted from after in system 3.Due to oil smoke, to enter fashionable resistance from interior air inlet 41 little, is easier to form negative pressuren zone, and enters from outward
It is larger that fashionable resistance is entered in air port 42, and negative pressure forms more difficult, for this purpose, drainage device 5 is additionally provided with range hood, centre is entered
The oil smoke that the oil smoke for entering and periphery enter is separated, so as to ensure the negative pressuren zone phase at interior air inlet 41 and external air inlet port 42
It is mutually independent.
Embodiment one
In the present embodiment, blower fan system 3 is using double air intake centrifugal blower fans, the first air inlet 31 of blower fan system 3 with from
The oil smoke correspondence that interior air inlet 41 is entered, the second air inlet 32 of blower fan system 3 are corresponding with the oil smoke entered from external air inlet port 42.
In the present embodiment, the first air inlet 31 is the air inlet on rear side of blower fan system 3, and the second air inlet 32 is positioned at blower fan system
Air inlet on front side of system 3.When being worked due to range hood, the oil smoke opposite posterior on front side of exhaust fume collecting hood 1 is more, therefore, entered outward
Air port 41 enter oil smoke be incorporated into closer to front side the second air inlet 32.
The oil smoke that interior air inlet 41 is entered is directed to the first air inlet 31 of blower fan system 3, drainage device 5 by drainage device 5
Enter in fan shroud 2 after from smoke deflector 4 through the air inlet 11 of exhaust fume collecting hood 1, air inlet 11 of the drainage device 5 less than exhaust fume collecting hood 1.
Drainage device 5 includes side wall 51, limits the drainage channel 511 of upper/lower terminal opening, open under drainage channel 511 in side wall 51
Mouth is corresponding with the interior air inlet 41 of smoke deflector 4, and the upper shed of drainage channel 511 is corresponding with the first air inlet 31 of blower fan system 3.
Thus, when range hood works, most oil smoke is entered from interior air inlet 41, under the guiding function of drainage device 5, from blower fan
First air inlet 31 of system 3 is flowed in blower fan system 3；When remaining oil smoke is escaped outward, through outside annular it is outer
It is inhaled into during air inlet 41, the part for being located at 5 periphery of drainage device by the air inlet 11 of exhaust fume collecting hood 1 is flowed in fan shroud 2, directly
To the second air inlet 31 for reaching blower fan system 3.The path of oil smoke flowing is can be found in shown in the arrow in Fig. 2～Fig. 4.
To avoid from external air inlet port 41 oil smoke for entering from being directly entered the first air inlet 31 upwards from the rear side of fan shroud 2,
The upper end of drainage device 5 is abutted with the rear wall of fan shroud 2, to close oil smoke passage upwards, so that it is guaranteed that different air inlets enter
Enter.Further, since in the present embodiment, centrifugal blower is vertically placed, therefore, the upper end of drainage device 5 has matching
Vertical bending segment, when centrifugal blower slant setting, then the upper end of drainage device 5 is equally inclined.
Referring to Fig. 5 and Fig. 6, the width d2 of the width d1 of 5 lower end of drainage device less than 5 upper end of drainage device, thus can ensure that by
The air-flow that external air inlet port 42 is entered can bypass drainage device 5 and enter into the second air inlet 32 of blower fan system 3.It is new in this practicality
In type, width refers to range hood when in use, the part that user is faced size in the lateral direction.The lower end of drainage device 5
Inclined with horizontal direction, preferably 120 °～150 ° of inclined angle [alpha], to avoid causing oil smoke air-flow compressing, hinders
Air-flow passes through.
Embodiment two
Referring to Fig. 7, in the present embodiment, the difference with embodiment one is, blower fan system 3 is in parallel using two
Single air intake centrifugal blower fan, parallel connection refer to two centrifugal blowers each one end air inlet away from each other, and two centrifugal blowers are each
From the other end it is then adjacent to each other.Positioned at front side centrifugal blower the first air inlet 31 towards front side, and be located at rear side from
, towards rear side, the path of oil smoke flowing is identical with embodiment one, can be found in the arrow in Fig. 7 for second air inlet 31 of heart-wind syndrome machine
It is shown.
Embodiment three
Referring to Fig. 8 and Fig. 9, in the present embodiment, the difference with embodiment one is that interior air inlet 41 is in oval
Shape, accordingly, the under shed of drainage device 5 is also Long Circle.
Optionally, interior air inlet 41 can also adopt other such as circle, ellipses etc..
