In specific embodiment, the structure setting of range hood 1 reduces integrally-built appearance and size, realizes ultra-thin
Purpose of design is easily installed, while convenient for being hidden in cabinet.
In specific embodiment, the first smoking port 30 is different with the area of the second smoking port 40, therefore, by first in the unit interval
The air flow rate that smoking port 30 and the second smoking port 40 suck is different.Diversion division 20 can be adjusted according to specific actual use situation to carry on the back
Side and the value range of the angle a of horizontal plane 120 from the first smoking port 30 are come, and determine the air-flow in third flow channel 100
Nowed forming, and then fluid resistance loss can be reduced, while regional gas stream stream near except the first smoking port 30 can be made
Dynamic form is more smooth, expands and holds together cigarette range, reduces the fluid resistance loss of 1 Flow Field outside of range hood, realizes more preferably oil suction
Cigarette effect.
In specific embodiment, the structure setting of range hood 1 of the invention not only greatly strengthens the suction of range hood 1
Oil smoke effect, and make complete machine appearance cleaner and tidier, greasy dirt easy to clean, and production and manufacturing cost are reduced, it is promoted
Product performance and the market competitiveness.
In specific embodiment, as shown in figure 15, cooking stove 130 heats the utensil 110 being placed on thereon, and utensil 110 is due to heated
Oil smoke is generated, range hood 1 aspirates oil smoke, and arrow indicates the flow direction of oil smoke air-flow, when range hood 1 works, second
The suction airstream of smoking port 40 drives oil smoke movement so that oil smoke is gradually gathered in the aspiration ranges of range hood 1, and utilizes
Second smoking port 40 is pumped into part oil smoke so that part oil smoke converges after entering in the first flow 80 of the first installation ontology 102
Enter the second flow channel 90 of the second installation ontology 104, the oil smoke that part is not sucked at this time continues under the buoyancy of hot-air
Rise, and then be pumped into the third flow channel 100 of diversion division 20 by the first smoking port 30, and oil smoke is finally made to import second flow channel
90.That is, the flowing runner by the way that oil smoke is rationally arranged, guiding oil smoke thereby reduces oil suction in the flow direction of range hood 1
It is vortexed probability produced by changing because of air flow direction when smoke machine 1 works, reduces aerodynamic drag loss when air-flow flowing, reduces
Noise when product is run, enhance product holds together cigarette ability so that oil smoke can be swimmingly by inflow range hood 1, Jin Erzeng
Suction air quantity in big 1 unit interval of range hood, improves working efficiency, performance and the market competitiveness of product,
And reduce energy consumption.
In specific embodiment, as shown in Figure 16 and Figure 17, arrow shows in first flow 80, in second flow channel 90, the
The flow direction of air-flow in three runners 100 and near the first smoking port 30.By the way that the structure of range hood 1 is rationally arranged, make
The air-flow streamline obtained at the grid 50 of the first smoking port 30 and at the grid 50 of the second smoking port 40 is so smooth that be pumped into suction
Inside kitchen ventilator 1, and it is also smooth in the air-flow of 30 near zone of the first smoking port (especially above the first smoking port 30)
Ground is drawn into the grid 50 of the first smoking port 30.The structure setting not only greatly strengthens the smoke absorption effect of range hood 1,
And making product appearance cleaner and tidier, greasy dirt easy to clean reduces production and manufacturing cost.
