Description
Technical field
The present invention relates to a kind of range hoods, more particularly, to a kind of oil collecting system of range hood.
Background technology
Existing range hood is equipped with catchment cup, and catchment cup is generally all mounted on to dismountable type the bottom of exhaust fume collecting hood,
It can finally be fallen into catchment cup through the oil that blower fan system oil smoke separates and collects.Currently, a variety of oil suctions have been disclosed in the prior art
The oil collecting structure of smoke machine, such as the Chinese utility model of Patent No. ZL 96205439.9 (Authorization Notice No. is CN 2290788Y)
Disclosed in patent《Oblique arranged fan depth kitchen hood》, for another example (Authorization Notice No. CN of Patent No. ZL 96202373.6
Disclosed in Chinese utility model patent 2260974Y)《A kind of depth range hood》.Although above-mentioned existing oil collecting structure is set
Haggle over to be compact, but these oil collecting structures are only applicable to the only range hood there are one wind turbine.
Currently, for the harmful effect for overcoming back pressure belt as far as possible, people have been designed that the concatenated suction of two fans
Kitchen ventilator, this concatenated range hood of two fans increase the wind pressure of blower fan system by matching primary and secondary two-stage wind turbine, make wind
Machine system in a state of use, can obtain larger air draft flow there are larger back pressure, and primary and secondary two-stage wind turbine
For rotating speed without too high, noise is smaller, can meet the requirement of the efficiently quiet suction of range hood.This concatenated range hood of two fans
Secondary fan is usually located at the surface of main wind turbine, if the greasy dirt collected after the separation of secondary fan oil smoke passes through properly
Comb oil processing, then can pollute main blower fan system located directly below, and then influence the normal operation of main blower fan system, very
To being damaged to, in addition, range hood inner cavity environment can also be polluted and lead to the damage of electric component.In conclusion for existing
Some has series connection two fans system range hood, needs to be proposed a kind of completely new oil collecting system.
