Description
Technical field
The present invention relates to a kind of electrical equipment, refer in particular to a kind of ventilation fan.
Background technique
Ventilation fan is well known, a kind of as shown in Figure 6 discharge type ventilation fan, and in framework 1, its rear portion is integrally formed with motor bracket 2, fixedly mounts motor 3 above, and flabellum 4 is installed on the axle of motor 3.Air-inlet cover 6 is installed, its outer switch curtain 7 and face shield 8 of also being equipped with on the framework front panel 5.During work, motor 3 rotations drive flabellum 4, and air (shown in arrow among the figure) is formed stable air-flow and discharged the room through framework 1 inside by the guiding function of air-inlet cover 6 camber lines.
Usually also have a kind of airflow direction and opposite ventilation fan shown in Figure 6, i.e. air inlet type.This still is that air in the space is ejected division according to replenish air in the space.According to these demands, MANUFACTURER has also been made corresponding product, i.e. air inlet type in the industry just.
Also have a kind of two-way type ventilation fan in addition, control motor positive or anti-phase running, reach air-breathing and purpose exhaust by switch.
But attraction type in the said goods and discharge type ventilation fan need MANUFACTURER to prepare two cover production moulds, two cover production lines, two kinds of different packings.Whole manufacturing, sale all are different two cover function modes, have increased burden to MANUFACTURER.Though the sort of in addition two-way type ventilation fan only needs a cover production mould, owing to the flabellum that the characteristics for two-way blowing design, the reason of the camber line of himself causes ventilation fan wind-force limited, thereby has influenced user's use.
Therefore a kind of need one mold just can be produced the air-breathing or energy exhaust of energy, and the ventilation fan that does not also influence wind-force has simultaneously just become MANUFACTURER to look forward to.
Summary of the invention
The objective of the invention is to, a kind of ventilation fan is provided, only need take forward or reverse installation can realize air-breathing or degassing function when mounted.
Be convenient narration, be defined as forward with the mounting type that constitutes the exhaust ventilation fan in the text description of the present invention and install, be defined as reverse installation with the mounting type that constitutes air-breathing ventilation fan.
For achieving the above object, a kind of ventilation fan provided by the invention comprises framework, motor, motor bracket, flabellum, and motor can forward or oppositely is installed in the framework, and flabellum is positioned at the middle part of framework; Also comprise an air-inlet cover, this air-inlet cover also can forward or oppositely is installed in the framework; Motor and the air-inlet cover flabellum of being separated by lays respectively at the two ends of framework.
Described ventilation fan, wherein motor is installed on the movable motor bracket, and this motor bracket is established some stent foots, can be installed in the framework or takes apart in framework; Wherein air-inlet cover is provided with some stent foots, also can be installed in the framework or takes apart in framework; Set firmly the supporting structure of the stent foot cooperation of some and said motor stent foot and air-inlet cover in the front and rear portions of frame inner wall.Be installed in the structural while of back support of frame inner wall at the motor bracket forward, the air-inlet cover forward is installed on the front support structure of frame inner wall, perhaps oppositely be installed in the structural while of front support of frame inner wall at motor bracket, air-inlet cover oppositely is installed on the back support structure of frame inner wall.
Described ventilation fan, wherein the front and rear portions supporting structure of frame inner wall is arranged along the same circumferential section of inwall respectively.
Described ventilation fan, wherein the front and rear portions supporting structure of frame inner wall is arranged along two circumferential sections of inwall respectively.This moment, arbitrary front and rear portions supporting structure all was arranged to non-same circumference respectively, that is to say not on same circumference, this is in order to reinforce motor bracket and air-inlet cover, owing to can produce vibration during motor operations, therefore several supporting structures by non-planar arrangement more help damping, reduce noise.
Described ventilation fan, wherein the quantity of the back and front supporting structure of the stent foot of the stent foot of motor bracket, air-inlet cover and frame inner wall is all identical with layout.Also can be designed to varying number and layout with aforementioned four, as long as be respectively equipped with the back and front supporting structure that the stent foot correspondence with the stent foot of motor bracket, air-inlet cover matches.
Described ventilation fan, wherein the front and rear portions supporting structure of frame inner wall is identical; Wherein the stent foot structure of the stent foot of motor bracket and air-inlet cover is identical.
Described ventilation fan, wherein a semi-cylindrical projection is respectively established in the front and rear portions supporting structure both sides of frame inner wall, the semi-cylindrical groove that can closely hold this projection is respectively established in the stent foot both sides of the stent foot of motor bracket and air-inlet cover, by closely cooperating of projection and groove, make being installed in the framework that motor bracket or air-inlet cover can be fastening.
Described ventilation fan, wherein the front and rear portions supporting structure of frame inner wall has a concave station, and the stent foot of motor bracket and the stent foot of air-inlet cover have a convex; The structure of this convex and concave station closely cooperates, and runs through fixedly connected with screw.
Described ventilation fan also is included in framework and is equipped with the switch curtain outward.
This shows advantage of the present invention:
The present invention is by setting firmly supporting structure on framework, make it air-inlet cover can conveniently be installed, again motor bracket can be installed conveniently, can install flexibly according to use condition, as long as exchange the change that air-inlet cover and motor bracket just can be realized airflow direction, thereby realize air inlet and degassing function, also make product that better interchangeability is arranged, reduced the mold design cost.
This structure can make flabellum be in same pipeline location all the time, and the pipeline taper that minimizing mould pattern draft is caused is to the influence of air inlet and exhaust performance.Its product have good interchangeability simultaneously, and convenient the installation, dismounting.Make things convenient for the user to safeguard just because of above-mentioned readily removable blade structure.
The ventilation fan of this invention is compared with the described two-way type ventilation fan of background technique, and air quantity is big, and noise is little, and applicability is strong.
