For improving the adaptability of above-mentioned smoke exhaust ventilator, be preferably near the cabinet back side of rear side exhaust outlet and set up a back side exhaust outlet, and be equipped with a back side seal closure with its coupling, simultaneously, the rear side exhaust outlet also is equipped with a rear side seal closure with its coupling.When normally using the rear side exhaust outlet, back side exhaust outlet is sealed.When the rear side exhaust outlet is inapplicable will use the back side exhaust outlet time, the rear side exhaust outlet is sealed.Because the back side exhaust outlet of this smoke exhaust ventilator is than the more close cabinet rear side of the back side exhaust outlet of common smoke exhaust ventilator, so the air channel is also more smooth and easy, exhaust resistance is also less, so desirable when though function ratio and fume exhaust effect are not used the rear side exhaust outlet, also than the obvious raising of common smoke exhaust ventilator.
The utility model reduces exhaust resistance to greatest extent because the starting point is to improve the air channel by the position that changes exhaust outlet, thus not only simple in structure, noise is lower, and also function ratio and fume exhaust effect significantly improve.
For verifying effect of the present utility model, I buy back a new common smoke exhaust ventilator from the market, with being fixed on the exhaust duct afterbody and testing with the small fan of tachometer interlock, repack it into new smoke exhaust ventilator by design of the present utility model then, use the same method again, condition test, this small fan is the rotating speed such as the following table of different azimuth before and after repacking:
Unit: rev/min
As seen from the above table, the back side, this smoke exhaust ventilator repacking back exhaust outlet left, air draft to the right, before the repacking of small fan rotating ratio respectively fast 3.1% and 22.7%; The air draft backward of rear side exhaust outlet, small fan rotating ratio reequip preceding back side exhaust outlet left, to the right, air draft respectively fast 22.1%, 74.4% and 21.3% backward.Be fixed on exhaust duct afterbody small fan rotating speed after this smoke exhaust ventilator repacking and significantly accelerate, show that the fume exhaust effect significantly improves.In addition, the noise of also finding repacking back smoke exhaust ventilator in test process obviously reduces.
