Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
The utility model embodiment 1 provides a kind of adjustable range hood of negative pressure area, as shown in Figure 1 comprising cabinet
1, blower 2 and exhaust fume collecting hood 3, blower 2 are arranged inside cabinet 1, and exhaust fume collecting hood 3 and cabinet 1 connect, further comprise control assembly and
Adjust component 4, control assembly be arranged inside cabinet 1, adjust component 4 be arranged on exhaust fume collecting hood 3, in this way, control assembly according to
The size of current smoke controls to adjust component 4, adjusts the area of 3 upper air inlet of exhaust fume collecting hood.
The utility model embodiment 2 provides a kind of adjustable range hood of negative pressure area, as in Figure 2-4 comprising case
Body 1, blower 2 and exhaust fume collecting hood 3, blower 2 are arranged inside cabinet 1, and it further comprises control assembly that exhaust fume collecting hood 3 and cabinet 1, which connect,
With adjusting component 4, control assembly is arranged inside cabinet 1, adjusts component 4 and is arranged on exhaust fume collecting hood 3, in this way, control assembly root
Component 4 is controlled to adjust according to the size of current smoke, adjusts the area of 3 upper air inlet of exhaust fume collecting hood.
Adjusting component 4 includes wing plate 41, baffle 42, electric pushrod 43 and fixed block 44, and baffle 42 is fixed on
In wing plate 41, one end of electric pushrod 43 is connect with fixed block 44, and the other end is connect with wing plate 41, and fixed block 44 is fixed on cabinet
On 1 inner wall, wing plate 41 is movably connected on exhaust fume collecting hood 3 by shaft, can rotate around the axis.
Assuming that the kitchen range on the only left side works, then opened in the corresponding regulating mechanism 4 of left side kitchen range after control assembly judgement
Wing plate 41, enter the wind region at this time and there was only that the left side is a part of, air inlet direction is corresponding with oil smoke generating region, in this way, air inlet face
Product, which reduces, can be improved intake velocity, enhance negative pressure；Wing plate 41 is opened, and air inlet can be declined 150- in the vertical direction
200mm generates point closer to oil smoke, improves oil smoke suction effect.
One end of wing plate 41 is movably connected on exhaust fume collecting hood 3 by shaft, and the other end of wing plate 41 is provided with integrated oil unit
411, two sides vertical with integrated oil unit 411 of wing plate 41 are provided with the skirt 412 to 42 side of baffle protrusion, on skirt 412
It is provided with the oil discharge outlet 4121 for pouring out the greasy dirt of collection, is additionally provided in wing plate 41 for connecting with electric pushrod 43
Hole 413, the position of oil discharge outlet 4121 is the least significant end after wing plate 41 is closed, in this way, opening wing plate when range hood is opened
41, greasy dirt accumulates in the upper surface of wing plate 41 by the cohesion filtering of baffle 42 at this time, and since wing plate 41 tilts, greasy dirt can be
Under gravity, the relatively low one end of wing plate 41 is accumulated to, when greasy dirt amount is larger, is overflowed in order to avoid greasy dirt from one end
One end of wing plate 41 is arranged in integrated oil unit 411 by situation, and integrated oil unit 411 forms certain cavity volume by five face closures, can
To put aside a certain amount of greasy dirt；After range hood is without using closing, wing plate 41 is closed, and oil discharge outlet 4121 is in a horizontal position,
Greasy dirt can flow to from oil discharge outlet 4121 from integrated oil unit 411, finally flow out under gravity from oil discharge outlet 4121.
Baffle 42 is at least two fanning strips disposed in parallel, and two straight flanges in fanning strip are fixed in wing plate 41,
In this way, the arc-shaped one end of fanning strip makes entire baffle be easy to open and withdraw.
It adjusts component 4 and is provided with two sets, left and right two parts of air inlet are controlled respectively, in this way, by the air inlet of range hood
Region is divided into left and right two parts, and adjusts the unlatching in air inlet region and the angle of unlatching by adjusting component 4 accordingly.
Two wing plates 41 connect and cover air inlet, complete cigarette；In this way, electric pushrod 43 works, wing plate 41 is pushed to move
Dynamic, wing plate 41 drives baffle 42 to open, and completes cigarette；In addition, working as range hood when not in use, two wing plates 41 are closed,
Completely close air inlet.
Control assembly includes acquisition unit and controller；Acquisition unit is used to obtain position and the concentration of oil smoke；Control
Device is flexible according to the data control electric pushrod 43 that acquisition unit acquires, and realizes the opening and contraction of wing plate 41, acquisition unit packet
Include position sensor and concentration sensor, in this way, by the position of position sensor and concentration sensor automatic identification oil smoke with
And concentration, and controller is passed data to, controller controls to adjust the open state of wing plate 41 in component 4 according to data, makes
The region that the air inlet wind direction of air inlet is generated towards oil smoke, meanwhile, controller can also adjust the running speed of blower 2, thus
Change the suction size of range hood.
In addition, as shown in figure 5, two wing plates 41 are closed, at this time 41 outer surface sum aggregate of wing plate when range hood is closed
3 surface of petticoat pipe is in same level, can't see the inside of range hood, and integraty is strong, brief beauty.
Application method: the position sensing when the kitchen range work for having side (assuming that left side kitchen range work), in control assembly
Device collects signal, and transmits signals to controller, and the adjusting component 4 in controller control left side works, and electric pushrod 43 pushes away
Dynamic wing plate 41 is mobile, and wing plate 41 drives baffle 42 to open, and completes cigarette, meanwhile, it is current that concentration sensor acquires signal judgement
The size of oil smoke amount, and according to the open state of this control wing plate 41, avoid deficiency in draught that oil smoke is caused to be not fully absorbed
Or air quantity causes greatly very much energy waste；When kitchen range when two sides work, two sets of adjusting components 4 control corresponding respectively
The open state of wing plate 41 makes it suitable for current oil smoke amount.
Using the above scheme, compared with prior art, when the utility model is used, judge that oil smoke generates by control assembly
Region and oil smoke amount size, and then by adjust component adjust air inlet area, make its meet current oil smoke amount with
And the position of oil smoke.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in
Change or replacement, should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should
It is subject to the protection scope in claims.
