Abstract
A plus and minus pressure gas flowing smoke and oil ventilator is provided with a mini axial flow blower, a turbine blower, an arc plate, and a flat horn shaped wind outlet. The mini axial flow blower runs via the flat horn shaped wind outlet blowing plus pressure horizontal gas flowing, the horizontal plus pressure gas flowing blows the smoke and oil to the turbine blower, which produces the minus pressure to suck and exhaust the smoke and oil to the outdoor through the exhaust wind pipe. The advantages of the plus and minus pressure gas flowing smoke and oil ventilator are to have a big smoke and oil ventilation area, to use less motor power than that of the common ventilator, and to save electricity energy.
Description
Affiliated technical field
The utility model relates to the range hood device that use in a kind of kitchen.
