Specific implementation mode
The present invention is described in detail with reference to the accompanying drawings and detailed description.Following embodiment is only used for more clear
Illustrate to Chu technical scheme of the present invention, and not intended to limit the protection scope of the present invention.
As shown in Figure 1, a kind of novel left-right movable type rectification plate of range hood suitable for dual-range-head for the present invention is illustrated
Figure cowling panel schematic diagram.The novel rectifying plate includes the movable rectifying plate 1 that can be moved left and right and oil smoke shroud rim 2;
The movable rectifying plate cowling panel 1 that can be moved left and right is moved to the small side of fume pollution amount, dirty to oil smoke is generated
Dye measures the big more exhaust areas of side kitchen range, and can be adjusted and be moved left and right according to the ratio of the amount of pollutant of two kitchen ranges
Distance, form corresponding different exhaust air rate ratios above kitchen range;If both sides contaminant capacity is suitable, the shifting that can be moved left and right is kept
Dynamic formula cowling panel 1 is in not to be moved relative to the centre position of dual-range-head;It is such then can flexibly control both sides air draft flow proportional
And matched with kitchen range service condition, better oil smoke trapping effect is obtained, oil smoke arresting efficiency is improved.
The present invention is applied in kitchen model as shown in Figure 2, and simplation verification is carried out to its arresting efficiency effect of optimization.Mould
Quasi- verification process is as follows:
Will as shown in Figure 3 in original square cowling panel kitchen ventilator model with carry novel left-right movable type cowling panel
Kitchen ventilator model is separately added into kitchen model and carries out CFD simulations, since kitchen range is on right side in model, then cowling panel sidesway to the left
Dynamic 35mm.Range hood cowling panel is different, and other conditions and setting are consistent.Smoke particle object is loaded after the convergence of flow field, in
Its particle capture efficiency is calculated in the simulation of 201711254268.8 method of state's patent, is illustrated in figure 4 original cowling panel and new
The analog result of type left-right movable type cowling panel a, it is seen that arresting efficiency of mobile cowling panel is significantly high in small air quantity
In original cowling panel, oil smoke trapping is better under small air quantity.
As shown in figure 5, for (Y is the seat in Fig. 2 in room Y=1.5m for the kitchen ventilators of two kinds of cowling panels under same traffic
Parameter, indicate room width direction) section flow field simulation speed cloud atlas, it can be seen that since both sides air draft air-flow enters cigarette
The low velocity eddy that chamber generates collision and formed reduces, and air draft control range in right side expands.Analysis is it is found that contaminant capacity is larger
Corresponding air draft region area increases above the kitchen range of side, and corresponding exhaust air rate and air draft control range increase, and are conducive to pollute
Object, which rises to after generating at cowling panel, mainly drains from apart from close side air draft region;And other side air draft region area is corresponding
Reducing, exhaust air rate and air draft control range is caused to reduce so that the pollutants from cooking fume of rising is acted on by the sucking of the other side to be reduced,
It is more promoted to be discharged from distance nearlyr side air draft region.After oil smoke air-flow rises arrival cowling panel due to heat buoyancy, take the lead in
Into the speed control range of right cover mouth, air draft effect in right side is strong, and air draft effect in left side is very weak, and most of oil smoke is from right side
Drain, compared with using original cowling panel, motion path shortens, and efflux time shortens.Achieve the purpose that quickly to drain oil smoke, drop
Low oil smoke spreads excessive possibility, enhances oil smoke trapping ability and anti-interference ability.
As shown in fig. 6, be oil smoke concentration analog result of the kitchen ventilator in the room sections Y=1.5m of movable rectifying plate,
It can be seen that some high concentration oil smoke drop along cowling panel right side edge is directly entered petticoat pipe, reduce that oil smoke is excessive to be diffused into interior
Risk.
When actual production designs, adjustment distance can be determined apart from size according to the actual conditions of kitchen range by moving left and right, and be adjusted
Rational gear can be arranged in perfect square formula;Cowling panel is not limited to rectangular, achieves the goal.
