Description
Technical field
The present invention relates to a kind of blower volute tongues.
Background technique
Multi-wing centrifugal fan is and wide because having many advantages, such as that compact-sized, pressure coefficient is high, discharge coefficient is big and low noise
It is general to be applied in range hood.The centrifugal blower of existing range hood is provided with volute tongue, the work of volute tongue near volute outlet
With being to prevent portion gas in spiral case internal circulation flow.Through experiments, it was found that impeller outlet air-flow is stronger to the impulse ratio of volute tongue,
Gas flowing near volute tongue is complex, and is affected to fan performance.In addition, rotate in air can band for object
Dynamic surrounding fluid rotation, rotates the circulation and fluid interaction of generation, increases the fluid velocity of object side, another effluent
Body speed reduces, this phenomenon is known as Magnus effect.Currently, people for blower volute tongue structure improvement mainly from drop
Low fan noise considers that such as application No. is 201210210890.X (application publication numbers 103512064 with vortex angle is eliminated
A " smoke exhaust ventilator and its spiral case, volute tongue " disclosed in Chinese invention patent application), volute tongue includes inner concave, and inner concave is
Smooth surface to keep the air-flow at volute tongue more smooth, and then advantageously reduces noise, although, the improved volute tongue by
There is part to slow down among volute tongue in air-flow and advantageously reduce noise, but since the upper joint face of volute tongue is plane, volute tongue two
The front and back air-flow of side is normally gone out, and since middle air flow speed is big, thus middle air flow and front and back air-flow are almost in same a period of time
Quarter impacts the joint face, and noise superposition is caused to increase, moreover, the volute tongue is not examined from enhancing gas circulating angle
Consider, the air quantity and wind pressure of blower can not be effectively improved.In conclusion needing further to change existing blower volute tongue structure
Into.
Summary of the invention
First technical problem to be solved by this invention is for above-mentioned state of the art, and providing one kind can be reduced
Reflux effectively promotes the blower volute tongue of fan delivery and wind pressure.
Second technical problem to be solved by this invention is that it is further to provide a kind of energy for above-mentioned state of the art
The blower volute tongue for enhancing gas circulating, promoting air quantity and wind pressure.
The present invention solves technical solution used by above-mentioned first technical problem are as follows: the blower volute tongue, including volute tongue sheet
Body, it is characterised in that: the lip of the tongue of the volute tongue ontology is provided with mounting groove, the mounting groove along volute tongue ontology length direction
Distribution, is equipped with column spinner, the both ends of the column spinner are separately mounted to the antetheca and rear wall of the mounting groove in mounting groove
On, the actuator for driving the column spinner rotation is installed on the antetheca or rear wall of the mounting groove.
Preferably, the both ends of the column spinner have outwardly extending installation axle, and wherein the installation axle of one end is mounted on
On the antetheca of tankage, other end installation axle is mounted on the rear wall of mounting groove, the actuator use motor, the motor it is defeated
Shaft passes through the antetheca of mounting groove or rear wall and is connected with corresponding installation axle.
Further preferably, the cross section of the column spinner is circle, and accordingly, the mounting groove has and the column spinner
The arc-shaped concave to match.
Further preferably, the upper wall surface of the volute tongue ontology is training wall, and the lower wall surface of volute tongue ontology is reflux wall, described
Column spinner is engaged between training wall and reflux wall, also, the smooth surface mistake on the surface of column spinner and training wall, the wall that flows back
It crosses.
It is that the blower volute tongue is on column spinner surface that the present invention, which solves technical solution used by above-mentioned second technical problem,
It is formed with pit.After pit is set, the frictional force of column spinner and air can be increased, further enhance gas circulating, make gas
It deflects more obvious, and then can further promote air quantity and wind pressure.
Further preferably, the pit is round pool, and the depth of pit is 0.2mm~0.5mm.
Pit has can be there are many distribution mode, as a preferred embodiment, and pit is set to the interlude region of column spinner,
And the density of pit is maximum in close column spinner midline, and gradually becomes smaller towards rear and front end.
In order to increase the fluid velocity of volute tongue front and rear sides, the pit is set to two sections of the front and back region of the column spinner.
Further preferably, the pit is covered with the whole surface of column spinner, and the density of pit is close to column spinner middle line
It is maximum to locate density, and is gradually become smaller towards rear and front end.
As another preferred embodiment, the diameter of the column spinner is in gradual change, also, the diameter of column spinner is certainly intermediate forward
Both ends gradually become smaller afterwards.In this way, two sides deflect air-flow forwards, backwards, keep outlet air-flow more uniform.
As another preferred embodiment, the diameter of the column spinner is in gradual change, also, the diameter of column spinner is certainly intermediate forward
Both ends become larger afterwards.In this way, deflecting front and rear sides air-flow to middle part.
Compared with the prior art, the advantages of the present invention are as follows: the blower volute tongue passes through the lip of the tongue installation in volute tongue ontology
Magnus effect can be can use relative to the column spinner of volute tongue ontology rotation, the lip of the tongue of volute tongue is made to generate gas circulating, from
And deflect the fraction collided with volute tongue the lip of the tongue towards air outlet, reflux gas is reduced, to promote air quantity and wind pressure.Separately
Outside, by that can increase the frictional force of column spinner and air, further enhance gas circulating in column spinner surface setting pit,
Keep gas deflection more obvious, and then can further promote air quantity and wind pressure.
