Specific embodiment
The utility model is further described with the following Examples.
Embodiment 1.
As shown in Figs. 1-2, a kind of swimming ring type smoke exhaust ventilator, is provided with smoke machine main body 1, and the smoke machine main body 1 is provided with
Horizontal positioned swimming round shell 2, shell 2 offer multiple air inlet groups 3.
The shell 2 of smoke machine main body 1 is designed to swimming round by the embodiment, and external form is novel, oil smoke adsorption effect is obvious, point
Air inlet group 3 is not opened up respectively on the inside-and-outside ring face of shell 2.
Air inlet group 3 in the embodiment be the air inlet group 3 that is connected to the same end in air duct 4 be referred to as it is same into
Air port group 3.
Each air inlet group 3 is single hole arrangements or porous structure, is not regarded in the structure that air inlet assembles similar filter screen
As multiple air inlets, but same air inlet group 3.
By the shell 2, smoke machine main body 1 is formed using 2 edge of shell as the inner space area 11 on boundary, 2 edge of shell
The boundary portion of composition is defined as space interface, and the part other than the interface of space is defined as outer spare areas 12.
Oil smoke only moves through air inlet group 3 in 12 range of outer spare areas, along the outer surface of shell 2 and is inhaled into
Air duct 4 inside smoke machine main body 1, oil smoke do not enter any inner space area 11 before entering air inlet group 3.
Since the outside wall surface of shell 2 has certain curvature, after causing oil smoke to contact outside wall surface, the original based on Coanda effect
Reason can be such that the outside wall surface of oil smoke attachment shell 2 rises.
Meanwhile inside air duct 4 being in negative pressure state relative to the oil smoke in outer spare areas 12, it can be directly by oil smoke from outer
Portion's area of space 12 is extracted by air duct 4 to inner space area 11.
2 are equipped with the air duct 4 being connected to air inlet group 3 in the shell, are equipped at the smoke outlet 6 of the smoke machine main body 1
Exhausting component 5, the air duct are assemblied in 2 top smoke outlet 6 of shell.
The air duct 4 is at least provided with a smoking channel, and every smoking channel is at least connected to an air inlet group 3.
When being provided only with a smoking channel, smoking channel can be connected to multiple air inlet groups；When being equipped with, a plurality of smoking is logical
When road, each one air inlet group of the corresponding connection in smoking channel makes each air inlet group have independent smoking channel.
Air inlet quantity is more, and distribution is more intensive, and smoking effect is better.
It should be noted that the swimming ring type smoke exhaust ventilator in the embodiment, according to aerodynamic principle, by shell 2
It is designed like the round shell 2 of swim ring, and using the inner air in kitchen, forms air-flow on 2 surface of shell, then by oil smoke
Be mixed into air-flow and extract out together, very good solution oil smoke spread the problem of.
Embodiment 2.
A kind of swimming ring type smoke exhaust ventilator, other feature is same as Example 1, the difference is that: as shown in Fig. 2, should
Oil smoke is passed through inside exhausting component 5 by embodiment in order to prevent, is polluted, different according to oil smoke flux, will smoking channel into
Row classification, and by the biggish air duct 4 of oil smoke flux directly the row of connection smoking channel, make oil smoke without exhausting component 5 inside.
Specifically, the smoking channel includes cleaning air inlet duct 41 and oil smoke air inlet duct 41, air inlet duct 41 and exhausting are cleaned
Connection that the inlet end of component 5 is seamless, oil smoke air inlet duct 41 are connected to smoke outlet 6.
The air inlet group 3 be provided with for the cleaning air inlet group 31 that is connected to of cleaning air inlet duct 41 and be used for and oil smoke
The 31 oil smoke air inlet group 31 of cleaning air inlet group that air inlet duct 41 is connected to.
The installation site of cleaning air inlet group 31 in the embodiment is higher than the position of oil smoke air inlet group 31.
Cleaning the air inlet group 3 that air inlet duct 41 is connected to is cleaning air inlet group 31, the air inlet that oil smoke air inlet duct 41 is connected to
Group 3 is oil smoke air inlet group 31.
It is most of after oil smoke attachment 2 outer surface of shell is moved to certain altitude since oil smoke is generated from 2 bottom of shell
Oil smoke corresponding air inlet group 3 siphons away on path.
The relatively high cleaning air inlet group 31 in position extracts the fresh air of kitchen headspace, is exhausting component 5
Inlet end provides fresh air.
It is that cleaning air inlet group 31 and oil smoke air inlet group 31 are specifically defined and being divided below:
2 highest point of shell is defined as Pm, coordinate Pm(Xm,Ym,Zm)；The central point of the cleaning air inlet group 31
For PClean air inlet group 31, coordinate PClean air inlet group 31(XClean air inlet group 31,Y Clean air inlet group 31,ZClean air inlet group 31), the center of oil smoke air inlet group 31
Point is POil smoke air inlet group 31, coordinate POil smoke air inlet group 31(XOil smoke air inlet group 31,YOil smoke air inlet group 31,ZOil smoke air inlet group 31), 0.5≤ZClean air inlet group 31/Zm≤
1,0≤ZOil smoke air inlet group 31/Zm≤ 0.5, and ZOil smoke air inlet group 31< ZClean air inlet group 31。
It should be noted that oil smoke will not be passed through inside exhausting component 5 by the air duct 4 in the embodiment, but by clear
The external fresh air that clean air inlet duct 41 sucks generates primary air, and the oil smoke in oil smoke air inlet duct 41 is extracted to row's smoking channel
Interior discharge.

Any one the flatlike structure covered above hearth such as face.
Guide surface of the outer surface of the shell 2 as oil smoke moving direction, and it is non-formation for gathering being provide with for oil smoke
Region.
The setting of air inlet group 3 quantity is more, and oil smoke absorption point is abundanter, and oil smoke adsorption effect is more obvious.
The shell 2 is provided with n air inlet group 3, and each air inlet group 3 is same with 1 inside air duct 4 of smoke machine main body respectively
One end connection, each air inlet group 3 are single hole arrangements or porous structure.
The air inlet group 3 that n air inlet group 3 is connected to from different 4 ends of air duct, for example, assembling class at air inlet group 3
Like netted structure is filtered, the air inlet group 3 of filter screen covering is considered as same air inlet group 3.
The central point of each air inlet group 3 is respectively P0、P1、……、Pi、……、Pn-1；And n >=2,1≤i≤n-1, and i
It is all positive integer with n, and n is more than or equal to 2, with any one central point P in the central point extreme lower position of air inlet group 30,For
Origin establishes three-dimensional system of coordinate.
Passing through P0And in the plane that is parallel to the horizontal plane, to cross P0And orthogonal two straight lines are defined as X-axis and Y
Axis will pass through P0And the straight line to intersect vertically respectively with X-axis and Y-axis is defined as Z axis, P0It is P in the coordinate of three-dimensional system of coordinate0
(X0,Y0,Z0)=P0(0,0,0)。
Air inlet group 3 in the embodiment not in the same plane, therefore, to the defined below of air inlet coordinate:
The central point of the n air inlet group 3 is P in the coordinate of 3-D walls and floor0(0,0,0)、P1(X1,Y1,
Z1)、……、Pi(Xi,Yi,Zi)、……、Pn-1 (Xn-1,Yn-1,Zn-1), P0(0,0,0)≠Pi(Xi,Yi,Zi), and PiTo Pn-1In
Z axis coordinate at least in the presence of one is not 0.
It should be noted that 3 quantity of air inlet group being arranged in the embodiment is more, oil smoke adsorption effect is better, simultaneously
All air inlet groups 3 are not at same plane, and the opening direction of any two air inlet group 3 is all different, can be effective
To from all directions oil smoke complete absorption.
Embodiment 4.
