Summary of the invention
the purpose of this utility model is for above-mentioned deficiency, and can not accumulate grease in a kind of blower fan proposed, and oil smoke discharge rate is high, blower fan does not need cleaning, noise is little, when not increasing power of fan, can improve the Multi-stage jet negative pressure suction type smoke exhaust of smoke exhaust ventilator smoke discharging effect.
technical solution of the present utility model is: comprise casing and be located at the blower fan in casing, and smoking port and blast pipe, it is characterized in that: the air outlet of blower fan is provided with a Multi-stage jet generator, described Multi-stage jet generator comprises Multi-stage jet pipe and is located at the Multi-stage jet pipe outer cover outside Multi-stage jet pipe, the air outlet of blower fan is connected with the air inlet of Multi-stage jet pipe, the air outlet of Multi-stage jet pipe is connected with blast pipe, be provided with airflow accelerator in the centre of Multi-stage jet pipe, smoking port is located at the below of Multi-stage jet pipe outer cover.
multi-stage jet pipe described in technical solution of the present utility model is end to end between at least two jet pipes, and the big open end end of jet pipe is air inlet, and little opening end is air outlet.
the section configuration of the Multi-stage jet pipe described in technical solution of the present utility model is circular or square or rectangle or other geometry.
airflow accelerator described in technical solution of the present utility model is two ends is fairshaped cylinder.
the utility model is the fluidic generator being provided with a Multi-stage jet pipe and multiple negative pressure suction inlet between the air outlet and blast pipe of blower fan, make use of the flowed energy that blower fan produces more fully; Blower fan of the present utility model does not contact with oil smoke, therefore blower fan is without grease, and blower fan does not need cleaning; Its power of fan of domestic cooking fume remover is general all at more than 230W on the market at present, and the centrifugal blower power that the utility model adopts is only 120W, energy-conservation about 50%; Model machine of the present utility model reaches 99.8% ~ 100% through statutory machinery's testing result oil smoke discharge rate, and kitchen fume discharge rate is higher than range hood commercially available at present, and through one month try out, kitchen can't smell greasy smell; The noise of current existing lampblack absorber is 50 ~ 55 decibels, and noise of the present utility model is only 47 decibels, lower than the noise of current existing lampblack absorber.
