The bottom-up air-flow that smoke exhaust ventilator ontology 1 generates cooperatively forms the effect of similar cyclone.
In a kind of possible embodiment, Fig. 6 is that a kind of kitchen fume shown according to an exemplary embodiment extracts
The structural schematic diagram of the air curtain device of equipment.As shown in fig. 6, the air curtain device 3 includes: second shell 31, the second wind chamber 32,
Air outlet 33, the second blast orifice 34, the second blast structure 35, air guiding wall 36.
As shown in fig. 6, the cross sectional shape of the second shell 31 is annular；As shown in Fig. 2, the second shell 31 surrounds
Outside the cross blowing device 2；As shown in fig. 6,31 inner hollow of second shell forms the second wind chamber 32；Air outlet
33, it positioned at the bottom of the second shell 31, is formed by the gap at 31 top of second shell, which is described the
The outlet of two wind chambers, 32 interior air-flow；Second blast orifice 34 is an opening in the second shell 31；Second blast orifice 34
For the import of 32 interior air-flow of the second wind chamber；Second blast orifice 34 can be in any position of the second shell 31, preferably
, as shown in Fig. 2, on the shell wall in the outside that the second blast orifice 34 can be located at second shell 31.Second blast structure 35, setting
At second blast orifice 34, gas is conveyed into the second wind chamber 32 for passing through second blast orifice 34 at work
Stream, then, the air-flow in the second wind chamber 32 is blown out from the air outlet 33, and the air-out direction of the air outlet 33 makes institute
The air-flow of the blowout of air outlet 33 is stated to the flows of the second shell 31；Air guiding wall 36 is 31 outer wall of second shell
On gas from the air outlet 33 to the part shell wall of 31 bottom of second shell, for guiding the air outlet 33 to blow out
Stream, so that the air-flow that the air outlet 33 is blown out moves from the top toward the bottom and to far from the smoke exhaust ventilator axis
The direction of line tilts, i.e., the air-flow moves remoter from smoke exhaust ventilator central axes more down.
As shown in Fig. 2, the air curtain device 3 can be formed from top to bottom and towards remote when using this kitchen fume extracting device
From the inclined air curtain of center position, under the action of this shape air curtain, the oil smoke generated when cooking can be swept along well
Inside air curtain, when air curtain arrives at kitchen range platform 4, under the blocking of kitchen range platform 4 and under 1 suction of smoke exhaust ventilator ontology,
Air-flow will continue to inwardly convey oil smoke towards the direction of smoke exhaust ventilator ontology 1, can greatly promote the air draught efficiency of smoke exhaust ventilator,
The blocking of air curtain also reduces the probability that oil smoke leaks to kitchen open spaces simultaneously.
Here, which can be the tubular structure of closed ring, be also possible to the tubulose knot of semiclosed annular
Structure.
Here, when the second shell 31 is the tubular structure of closed ring, the hollow inside of the second shell 31 is just
The second wind chamber 32 of closed ring can be formed.Air curtain device 3 is at work, so that it may form the air curtain of cone column type, be located at wind
Oil smoke among curtain will all be swept along inside air curtain, and the probability that oil smoke leaks to kitchen open spaces is reduced.Here it needs
It is noted that the closed ring can be oval ring, it is also possible to rectangular loop, or other special-shaped annulars, herein
With no restrictions, as long as the kitchen range on kitchen range platform can be trapped among centre.
Here, exemplary when the second shell 31 is the tubular structure of semiclosed annular, such as " C " type or " Π " type
Tubular structure when, which can be placed on kitchen range platform by user when using the air curtain device, by this second
One end that shell 31 is open is towards wall, so that the kitchen range on the kitchen range platform are trapped among by air curtain device and the wall in kitchen together
Centre, in this way, air curtain device is at work, so that it may be formed with the air curtain of the cone column type of opening, the oil smoke among air curtain
It will all be swept along inside air curtain, opening portion, will not be to outward leakage oil smoke due to the blocking of wall 4.
Here, Fig. 7 is a kind of the quick-fried of the air curtain device of kitchen fume extracting device shown according to an exemplary embodiment
Fried structural schematic diagram.As shown in fig. 7, the second shell 31 includes shell 311 and inner casing 312, the shell 311 is located at institute
The outside of second shell 31 is stated, the inner casing 312 is located at the inside of the second shell 31；Here inside refers to second shell
Close to the side at 31 center of second shell on 31, outside refers to the side in second shell 31 far from 31 center of second shell.Such as
This sets shell and inner casing for second shell 31 to make respectively, is surrounded by shell and inner casing and forms wind chamber, simple process, system
Facilitate.Certainly, if technique may be implemented, which can also be with integral production, herein with no restrictions.
Wherein, the gap is formed between the top of the shell 311 and the top of the inner casing 312, which is
Air outlet 33.The bottom of the shell is connect with the sealed bottom of the inner casing, prevents from leaking out, and the air-flow for keeping wind intracavitary can only be from
Air outlet 33 flows out.The top curved of the shell downwards determines the inner casing in portion is wrapped in, in this way, the air outlet formed
Flows of the air-flow that 33 air-out direction can make the air outlet 33 blow out to the second shell 31.
What needs to be explained here is that the length in the gap may include the length of the second shell 31.In this way, being formed
Air curtain top shape just it is identical with the top edge shape of second shell 31.It is exemplary, if second shell 31 is envelope
The air-flow of closed-loop shaped, the air outlet 33 blowout can form closed taper air curtain, kitchen range when culinary art and cookware can be produced
Raw oil smoke is swept along inside air curtain well, is placed oil smoke and is leaked.The width in the gap includes 0.1mm to 5mm.The gap
Width it is unsuitable too small, prevent the air curtain thickness to be formed small, oil smoke leaks, and the width in the gap also should not be too large, and prevents from being formed
The wind speed of air curtain is too small, and oil smoke leaks.The width in the gap can be in 0.1mm between 5mm, it is preferred that can be 1mm.
