Abstract
The utility model relates to a turbine boosted blower used for a smoke exhauster, which is composed of a motor and a motor frame. Both ends of an output shaft of the motor is fixedly provided with a turbofan and a turbine boosted fan which adopts secondary turbine with multiple blades and large torsion angle. The utility model adopts the working principle of an aviation turbine fan and solves the problem of relationship between noise and air quantity in the smoke exhauster, enlarging air quantity without increasing noise. The secondary turbine ensures wind pressure that the smoke exhauster needs, so the utility model makes smoke exhausters provided with the turbine boosted blower satisfy three indexes of smoke exhausters.
Description
The utility model is a kind of blower fan, particularly is used for the improvement of cooking-fume exhauster blower structure.
Range hood of Chu Shouing or title cooker hood all adopt centrifugal suction fan structure in the market.Because the centrifugal suction fan of this kind can produce high blast district and low blast district at work, during impeller work, have the deflection pressure that yaw wind is cut down output living, and this power acts on all the time on the impeller, be passed to motor bearings from impeller again, cause motor bearings to produce the deflection wearing and tearing.Therefore this range hood uses of a specified duration more, and noise is big more.Its another shortcoming is that centrifugal blower can't improve suction air volume under the restriction of range hood small product size.Estimate range hood and mainly contain three indexs, noise is low, and suction air volume is big, easy cleaning.Existing range hood can not be satisfactory to both parties because the problem that its centrifuge self structure exists is attended to one thing and lose sight of another solution range hood noise and air quantity problem.
The purpose of this utility model is, overcomes the shortcoming of above-mentioned range hood centrifugal blower structure, improves from design principle, solves the relation of noise and air quantity, and a kind of turbosupercharging blower fan of new structure is provided.
The purpose of this utility model is to realize like this.The turbosupercharging blower fan includes motor 3 and electric machine support 4, is installed with turbofan 5 and charging turbine fan 2 at the two ends of motor output shaft; Adopt leafy number, big torsional angle two-stage turbine.
The two-stage turbine fan that the utility model adopts, the first order is mainly used in air draught, and the second level is mainly used in the supercharging air draft.Two-stage turbine all adopts most blades, and big torsional angle becomes circular rector aerodynamic arrangement project organization, inhales a row high workload efficient to guarantee two-stage turbine one.During use, two-stage turbine is loaded in the duct formula range hood crust of weathering 1, blast equates on working surfaces everywhere in the crust of weathering, there is not the deflection active force, air current flow is smoothly smooth and easy, and machine operation is steady, so operating noise also reduces greatly, have only 55 decibels, be significantly less than China's range hood and be not more than 75 decibels standard.Because the utility model adopts the two-stage turbine one of leafy number, big torsional angle to inhale a row, guaranteed the work ratio of air draught and air draft, so exhaust air rate is very big, can reach 20m in theory again
3/ min.
The utility model is reformed from design principle, adopted the working principle of aerial turbo fan, solved the relation of fan noise and air quantity in the existing range hood, make the air quantity increasing and do not improve noise, the two-stage turbine structure has guaranteed the blast that range hood needs, thereby make the range hood that this turbosupercharging blower fan is installed, satisfied three indexs of range hood fully.The utility model is applied in the duct formula range hood crust of weathering, as long as unload electric machine support, each parts in the crust of weathering all can be pulled down, and it is convenient to clean.
Description of drawings:
1 crust of weathering, 2 charging turbine fans, 3 motors, 4 electric machine supports, 5 turbofan.
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is the utility model perspective view.
Embodiment: the turbosupercharging blower fan, include motor 3 and electric machine support 4, be installed with turbofan 5 and charging turbine fan 2 at the two ends of motor output shaft; Adopt leafy number, big torsional angle two-stage turbine.Turbofan has 18 blades, and the charging turbine fan has 20 blades.During use, two-stage turbine is loaded in the duct formula range hood crust of weathering 1, and electric machine support is fixed on the crust of weathering.
Claims (2)
1, a kind of turbosupercharging blower fan includes motor (3) and electric machine support (4), it is characterized in that being installed with at the two ends of motor output shaft turbofan (5) and charging turbine fan (2); Adopt leafy number, big torsional angle two-stage turbine.
2, according to the described turbosupercharging blower fan of claim 1, it is characterized in that turbofan has 18 blades, the charging turbine fan has 20 blades.
