Embodiment
The invention will be further described with the following Examples.
Embodiment 1.
As shown in figure 1, a kind of smoke exhaust ventilator of nonplanar structure, is provided with cigarette owner body 1, cigarette owner body 1 is provided with outer
Shell 11, the guide surface 2 of the outer surface of shell 11 as oil smoke moving direction, and the non-formation cover for being used to gather oil smoke sets region.
All outer surfaces of shell 11 can be used as guide surface 2, and the shell 11 does not contain plane, tapered plane or on-plane surface
Deng the flatlike structure covered above the kitchen range top of any one.
The outer surface of shell 11 is provided with multiple air inlets.
The non-cover that an air inlet group 12 is located at shell 11 at least be present and set regional location.
According to aerodynamic principle, after oil smoke produces, oil smoke can move along the outer surface of shell 11, and at least one
Non- cover sets the air channel 15 that the air inlet group 12 of regional location setting is sucked inside cigarette owner body 1.
Illustrate herein, the above-mentioned cover referred to sets region, refers to that what cigarette machine shell 11 formed holds together cigarette district domain, the stove below cigarette machine
Smog caused by stove primarily enters cigarette district domain, and set overlying regions by being arranged at cover because the reason for cover sets region
Air inlet sucks air channel 15, is finally discharged from exhaust opening.
Smoke exhaust ventilator in the present invention, the effect of shell 11, which is not configured to be formed, holds together cigarette district domain, but forms oil smoke movement
Attachment guide surface 2, oil smoke is not to be brought in the space that shell 11 is formed to be sucked away again, but allows oil smoke along shell 11
Surface is moved from bottom to top, and sucks air channel 15 by neighbouring air inlet group 12.
Therefore, it is this hair for cover of the prior art sets region that non-cover signified in the present invention, which sets region,
Bright non-cover sets region and refers to the region of shell 11 not for the purpose of holding together poly- oil smoke.
By shell 11, cigarette owner body 1 forms the inner space area 13 using the edge of shell 11 as boundary, the edge structure of shell 11
Into boundary portion be defined as space interface, the part beyond the interface of space is defined as outer spare areas 14.
Oil smoke moves through air inlet group 12 only in the range of outer spare areas 14, along the outer surface of shell 11 and inhaled
Enter the air channel 15 inside cigarette owner body 1, oil smoke does not enter any inner space area 13 before air inlet group 12 is entered.
Relative to the oil smoke in outer spare areas 14 it is in negative pressure state inside air channel 15 in oil smoke adsorption process, causes
The oil smoke of outer spare areas 14 is set smoothly to be adsorbed onto inside cigarette machine.
Air inlet group 12 is provided with n, and each air inlet group 12 connects with the same one end in air channel 15 respectively, each air intake
Mouth group 12 is single hole arrangements or loose structure.
The mistake for causing that air inlet group 12 is divided into multiple small-sized air inlets is equipped with order to avoid the end of air channel 15 be present
Filter screen shape or other structures, it is different air inlet groups 12 that can be mistaken as multiple small-sized air inlets.
Therefore, the air inlet group 12 that specific justice connects with the same one end in air channel 15 is same air inlet group 12.
It should be noted that the smoke exhaust ventilator for the nonplanar structure that the present invention designs is not provided with the structure of similar cover body,
Region is set in the absence of cover, reduces space occupied area, meanwhile, oil smoke can adhere to the outer surface flowing of shell 11, finally different
The air inlet group 12 of position is sucked inside cigarette machine and discharged, and strengthens the adsorption effect of oil smoke, improves the utilization of the outer surface of shell 11
Rate.
