Description
Technical field
The utility model relates to machine for kitchen use, especially a kind of range hood.
Background technique
Range hood has become one of machine for kitchen use equipment indispensable in Modern Family.Usual range hood includes top
Suction and near-absorption type, the principle that the range hood of top suction type utilizes hot gas to rise, suction is generated when cooking to be risen naturally
Oil smoke, additionally due to it is clean and tidy light and handy, occupy little space the advantages that, it is and in an increasingly wide range of applications, but since it is dynamic
Power source farther out from hearth, reduces the suction effect of power source, oil smoke cannot exhaust completely；The range hood of near-absorption type utilizes whirlpool
It is separate to flow wind pressure, will largely be absorbed apart from the closer oil smoke of hearth with form of arcs, the bad shadow to human health can be reduced
Ring, and power source is closer from hearth, will not substantially reduce the suction effect of power source, but due to the oil smoke rate of climb compared with
Fastly, or to minority the oil smoke escaped upwards is helpless.
Itself from range hood, the principal element for influencing smoke absorption effect is actually active air quantity under operating condition,
That is the actually active bigger smoke absorption effect of air quantity is better under the conditions of same, in order to promote the effective wind rate of actual condition,
Have some range hoods and use series connection blower, theoretically maximum static pressure is to series connection blower, but most strong wind twice of single blower
Amount is identical as single blower, although effective wind rate height and single-fan system under actual condition, its space promoted is ten
It is point limited, therefore need to be further improved.
