Description
Technical field
The utility model is related to a kind of wind turbine, which is mainly used in range hood, and the utility model further relates to inhale
Kitchen ventilator belongs to kitchen range technical field.
Background technology
Range hood is protection motor and detaches oil smoke now, generally sets an air inlet mesh enclosure in exhaust fume collecting hood air inlet,
As improved, the guard of an also useful plane is arranged on spiral case air inlet and can be rotated with impeller, sees the patent No.
Chinese utility model patent for ZL201420732722.1《A kind of turn centrifugal fume separator》(Authorization Notice No. is
CN204285570U)；Chinese utility model patent that can be with referenced patent number for ZL201620110299.0《A kind of tablet is taken out
Kitchen ventilator》(Authorization Notice No. CN205536025U)；
However there is following deficiency in the plane net cover of this structure in use：
First, noise is big, generate noise the reason of be plane guard and oil smoke contact surface it is not big enough, the guard institute of plane
The flue gas of process is the surface of vertical guard, and the swirling eddy generated after entering in kitchen ventilator with impeller rotation, which causes to conflict, to be drawn
Loud noise is played, in addition, rubbing when oil smoke passes through guard with guard generates ear-piercing howling；Secondly there are oil smoke separation
Phenomena such as being not thorough, the guard air inlet mode of plane do not meet air fluidics, and oil smoke cannot drain well.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of oil smoke separation effect for the above-mentioned state of the art
The good filtering type wind turbine of fruit.
Another technical problem to be solved in the utility model is to provide a kind of good range hood of oil smoke separating effect.
Technical solution is used by the utility model solves above-mentioned technical problem：A kind of filtering type wind turbine, including spiral case
And motor and impeller in spiral case, aforementioned spiral case have air inlet, the output shaft of aforementioned motor is connect with impeller, aforementioned
The air inlet arrangement of impeller face spiral case, it is characterised in that the wind turbine has further included filtering net cylinder, the filtering net cylinder rear end and electricity
The output axis connection of machine can simultaneously rotate together with impeller, and the air inlet of spiral case is stretched out in foregoing filtration net cylinder part.
Filtering net cylinder assembling structure is preferably set as follows：The middle part of the impeller is equipped with the wheel disc being connected with exporting axis, institute
The rear end for stating filtering net cylinder has an installation chassis, which is connected in aforementioned wheel disc front end face.This spline filter
Net cylinder and impeller can be divided among be adjusted on dynamic balance measuring instrument after assembled again, it is bad to complete machine to reduce dynamic balancing
The influence of performance, separately maintains convenient for the later stage, advantageously reduces maintenance cost.
There is through-hole, a locking nut is through the aforementioned through-hole of setting and is connected to wheel disc in the middle part of the installation chassis
On.Convenient for disassembly and assembly, stability is good.
The installation chassis offers multiple ventholes around through-hole.The presence of venthole can reduce installation chassis to leaf
Take turns the influence of interior air-flow.
The radical length of the filtering net cylinder rear end is less than the radical length of front end and is in flared.The conical surface extended out has
The filter area of bigger during operation, before oil smoke enters impeller, first passes through the primary dynamic mistake of conical surface ecto-entad of filtering net cylinder
Filter, then oil smoke there is the inside of the conical surface to be flowed to impeller direction again, by the secondary dynamic filtration of the filtering net cylinder conical surface, therefore,
Although single layer filter wire side, filtering of the oil smoke by Dynamic Networks twice can be realized, filter effect is further promoted.
Preferably, the front end of the filtering net cylinder is formed with air inlet through hollow shaft port.
Preferably, the filter mesh single hole area on the filtering net cylinder is 40mm2~400mm2。
Preferably, the filter mesh on the filtering net cylinder is diamond shape, circle, regular hexagon, ellipse or rectangular.
Preferably, the punching rate of the filtering net cylinder is 0.35~0.7.
A kind of range hood, including case, filtering type wind turbine and exhaust fume collecting hood, aforementioned filtering type wind turbine is set in case,
Aforementioned exhaust fume collecting hood is set on case lower port and with air inlet.
The outside that institute's filtering type states wind turbine is equipped with shroud upper panel, between having between the front end of the filtering net cylinder and shroud upper panel
Gap.
Compared with prior art, the utility model has the advantage of：It can be increased using the filtering net cylinder of stereochemical structure
For surface area when oil smoke passes through oil smoke separate mesh, the linear velocity of filtering net cylinder rotation is higher, and oil droplet is by the peripheral surface of filtering net cylinder
The probability of impact interception increases, and improves the effect of oil smoke separation, and staying in the drop on filtering net cylinder surface can flow and assemble, when
The centrifugal force that drop is subject to can throw away filtering net cylinder, therefore oil droplet is not easy to plug mesh after being more than skin-friction force.Oil smoke first from
The filter mesh on filtering net cylinder surface enters in filtering net cylinder, is entering in impeller, and the space in filtering net cylinder can play
Flue gas drainage effect, meet air fluidics, when oil smoke pass through filtering net cylinder when and filtering net cylinder between generate noise inside
Reduce ear-piercing howling.
