Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing embodiment.
As shown in Figures 1 to 4, the speed governing range hood includes:
Exhaust fume collecting hood 1, the lower section of cabinet 15 is connected to, there is outside jacket plates 11 and the docking of inner cover plate 12 to form, wherein inner cover plate 12
Middle part is provided with the oil smoke suction inlet 13 being connected with the volute inlet (not shown) of range hood.
The madial wall 12 of exhaust fume collecting hood 1 has vertical plane 121 and the inclined-plane being connected between vertical plane 121 and oil smoke suction inlet 13
122;Angle β between the inner surface of inclined-plane 122 and cowling panel 2 is 16 °~45 °, and β is 30 ° in the present embodiment.
Cowling panel 2, the middle part of inner cover plate 12 is arranged on corresponding to oil smoke suction inlet 13, collection cigarette is connected to by connecting plate 23
On cover 1;Oil smoke suction inlet can be opened when range hood works, oil smoke suction inlet is closed when range hood does not work;To be normal
Advise structure.Also other structures of the prior art can be selected as needed.
There is the first gap 21 and the second gap between the arranged on left and right sides edge of cowling panel 2 and the madial wall 12 of exhaust fume collecting hood 1
22。
The inner surface of cowling panel 2 is provided with the drive device 34 of first driving means 33 and second, and first in the present embodiment
The drive device 34 of drive device 33 and second is electric pushrod, and first corresponding to the push rod drive connection of electric pushrod adjusts wind
Block 31 and second adjusts pomphus 32.
Pomphus is adjusted, there are two pieces, including first adjusts pomphus 31 and second to adjust pomphus 32, by it relative to rectification plate surface
Slide to change the size of exhaust fume collecting hood cowling panel both sides oil smoke import;The first gap 21 and the second gap 22 is corresponded respectively to slide
It is connected on the inner surface of cowling panel 2;First adjust pomphus 31 and second adjust pomphus 32 width and corresponding first gap 21 and
The width in the second gap 22 is adapted, and when not working, two pieces are adjusted pomphus to close two gaps.
First adjust pomphus 31 and second adjust the non-triangle body structure of pomphus 32, surface thereof can be slidably supported be connected to it is whole
On the inner surface of flowing plate 2, it to the α between the outer surface of corresponding exhaust fume collecting hood madial wall and the inner surface of cowling panel 2 to pressing from both sides
Angle is 20 °;α angles can be selected in the range of 16 °~24 °, and good cooking fume guiding effect can be obtained in the range of this.
Smoke Sensor 4, there are two, for detecting the smokescope by two gaps;Plate below exhaust fume collecting hood 1 is set
On 14, two Smoke Sensors 4 are located at two outsides of cowling panel 2.
Smoke Sensor 4, the drive device 34 of first driving means 33 and second electrically connect the first (not shown) of control
Corresponding ports.
During work, control unit controls two drive devices according to the smokescope detected by two Smoke Sensors
Work.With adjusting, the turned position of pomphus is different, and its gap between exhaust fume collecting hood madial wall can change, so as to change
The negative pressuren zone of both sides, as shown in figure 5, to be adapted to the different smokescope situation in both sides, oil fume outer-runaway is avoided, obtains and preferably inhales
Arrange effect;Meanwhile adjust the angle of pomphus outer surface and exhaust fume collecting hood madial wall inclined-plane to be related to, there is good water conservancy diversion to make to oil smoke
With;Especially the angle of inclination on inclined-plane is more than the angle of inclination for adjusting pomphus outer surface, and oil smoke, which enters, to be adjusted between pomphus and inclined-plane
After passage, its speed is gradually reduced, oil smoke residence time relative increase, improves the separating effect of oil gas.
The working condition of two pieces of tune pomphus when showing three kinds of typical cases such as Fig. 2 to Fig. 4.
As shown in Fig. 2 when the left side oil smoke concentration that two Smoke Sensors detect is big, right side oil smoke concentration is small, control
Unit processed controls the work of the second drive device, and the push rod driving second of electric pushrod adjusts pomphus to stretch out, reduces entering for the second gap
Wind area;In the case where flow is constant via the oil smoke import suction increase corresponding to the first gap, the suction of left side oil smoke
Power increases, and effectively prevent left side oil fume outer-runaway;And right side is because oil smoke amount is few, escape that trend is small, relatively small flow is
Can suction it is clean.
As shown in figure 3, when arranged on left and right sides oil smoke is all very big, first, second tune pomphus stretches out, and reduces oil smoke import
Area, in the case where flow is constant, speed increase, avoid oil fume outer-runaway.
As shown in figure 4, when arranged on left and right sides oil smoke all very littles, first, second tune pomphus inwardly bounces back, increase by first,
Air-admitting surface corresponding to second gap, increase negative pressure hold together cigarette district.
