Description

The blower {The blower}

The present invention relates to a large-sized blower used for exhaust use in general factories, coating factories and the like, for use in adjusting humidity from a steel mill, for cooling a hot coil, or for steam exhausting,

A guide vane for guiding blowing air is provided on the outlet side of the inside of the fan body, and a plurality of blades formed at an angle with a predetermined angle are provided, so that the wind discharged from the blower is discharged more far away, And to maximize the effect of the indoor air circulation due to the improvement of the indoor air circulation.

The main cause of the indoor air pollution is that there are harmful gas and dust from the outside, but the problem of stagnation of the indoor air generated by blocking the indoor air from the outside is rather serious.

Accordingly, various devices for continuously circulating the air in the room without being stagnated have been developed and used.

Among them, a blower having an air circulation function is composed of a motor, a blowing fan for blowing wind forward by rotating the motor, and a grille for protecting the blower, so that there is no significant difference in configuration from the conventional fan.

However, in the conventional ventilator for indoor air circulation as described above, when air is blown out by the blowing fan, the air is dispersed and discharged in all directions, so that the blowing power is weak and the air circulation efficiency is lowered due to the remote blowing.

The present invention has been made in view of the above problems,

A guide vane for guiding blowing air is provided on the outlet side of the inside of the fan body, and a plurality of blades formed at an angle with a predetermined angle are provided, so that the wind discharged from the blower is discharged more far away, The present invention has an object of maximizing the effect of the indoor air circulation due to the improvement of the indoor air circulation.

Particularly, in the present invention, it is an object of the present invention to optimize the shape of a guide vane, that is, the number and arrangement angle of blades, thereby maximizing the effect of the indoor air circulation due to the improvement of the wind power.

In order to achieve the above object, according to the present invention,

A fan fitted to the shaft of the motor (8) and fixed by the fan fixing means; A fan body having the motor fixed to the inside thereof with the fan by a motor support and having front and rear nets connected to front and rear ends, respectively; A pedestal that is axially coupled to the fan body and rotatably supports the fan body; And a control box for driving the motor,

The through holes are respectively formed in both side plates of the pedestal and the through holes corresponding to the through holes are formed in the fasteners coupled to both sides of the fan body. So that the angle of the fan body can be arbitrarily adjusted,

A guide vane is separately provided at an outlet side of the fan body to induce a blowing direction and improve a wind power. The guide vane includes inner wings coupled in a radial direction from a cylindrical central portion, And an outer fixing part for fixing the inner wings to the inner wall of the fan body.

The inner wing and the outer fixing part are arranged so as to partially overlap with each other. At the overlapped part, the long holes are formed at positions corresponding to each other, whereby when the bolt is inserted through the long hole, the coupling length between the inner wing and the outer fixing part Can be finely adjusted.

In addition, the inner vanes of the guide vane are inclined in the direction opposite to the rotation direction of the fan, and the angle of inclination is 15 to 20 degrees.

As described above, according to the present invention,

A guide vane for guiding blowing air is provided at an outlet side of the inside of the fan body, and a plurality of blades formed by inclining at a predetermined angle are provided so that the wind blown from the blower can be discharged farther without being dispersed.

Therefore, the effect of the indoor air circulation due to the improvement of the wind power is greatly improved. In particular, the effect of the indoor air circulation is maximized by optimizing the shape of the guide vane, that is, the number of blades and the angle of arrangement .

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a perspective view of a blower according to the present invention, FIG. 2 is an exploded perspective view of a blower according to the present invention, FIG. 3 is an enlarged view of only a guide vane, 1 is a front view of a blower according to the invention.

The blower comprises: a fan (6) fitted to the shaft of the motor (8) and fixed by the fan fixture (61); The motor 8 is fixed together with the fan 6 by the motor support 81 and the front body 4 and the rear body 5 are connected to the fan body 3 and rear body 5, ; A pedestal (2) axially coupled to the fan body (3) to support the fan body (3) in a rotatable state; And a control box 7 for driving the motor 8,

A through hole 22 is formed in both side plates 21 of the pedestal 3 and a through hole 32 corresponding to the through hole 22 is formed in a fastening hole 31 coupled to both sides of the fan body 3, And the handle 9 penetrates through the through hole 22 and the through hole 32,

And the operator can arbitrarily adjust the angle of the fan body 3 by using the handle 9.

The motor 8 is seated on the motor support 81 and the motor support 81 is fixed in the middle position of the inner wall of the fan body 3.

The fan body 3 has a cylindrical shape and must be sufficiently sized to accommodate the motor 8 and the fan 6 therein.

The front and rear nets 4 and 5 are joined at the front and rear ends of the fan body 3 and can be coupled by various methods. In the illustrated embodiment, however, a bolting method is used .

The control box 7 is for controlling the operation of the motor 8 and is not limited in its mounting position. However, in the illustrated embodiment, the control box 7 is coupled to the outer wall of the fan body 3 for compact coupling .

In the present invention, a guide vane 1 is separately provided at the outlet side of the inside of the fan body 3 for guiding the blowing direction and improving the wind power.

The guide vane 1 includes inner vanes 12 radially joined in a radial direction from a cylindrical central portion 14 and an outer fixing portion 14 for fixing the inner vanes 12 to the inner wall of the fan body 3. [ (11).

The inner vane 12 and the outer fixing part 11 are arranged so as to partially overlap each other and the overlapped portions are respectively formed at positions corresponding to the long holes 13 so that the bolts are coupled through the long holes 13 The coupling length between the inner blade 12 and the outer fixing part 11 can be finely adjusted.

The outer fixing part 11 is coupled to the inner wall of the fan body 3 and may be coupled by various methods such as welding or bolting.

On the other hand, the inner vanes 12 of the guide vane 1 are inclined at a predetermined angle so that the wind blown from the fan 6 is not dispersed but discharged farther, The effect of air circulation can be maximized,

The inner vanes 12 of the guide vane 1 are formed to be inclined in a direction opposite to the rotation direction of the fan 6. If the inclination is too large, there is a problem that the wind power is lowered, It is preferable that the inclination angle of the inner blade 12 is set to 15 to 20 degrees. (See Fig. 3)

On the other hand, the inner vanes 12 of the guide vane 1 are arranged radially while maintaining the same angle with each other, and the width and the number of the inner vanes 12 should be designed to be sufficient to guide the air flow.

Hereinafter, the operation of the present invention will be described.

When the fan of the present invention is operated by applying power as shown in FIGS. 1 and 2, the inner fan 6 rotates by the motor 8 to forcibly forward the air on the rear side.

The air forcedly forwarded by the fan 6 in this way rotates in the same direction as the rotation direction of the fan 6 and passes through the guide vane 1 installed on the front side. At this time, Since the inner blades 12 of the guide vane 1 are formed to be inclined in the direction opposite to the rotating direction of the fan 6,

The air introduced into the guide vane 1 causes a vortex phenomenon in which the air is discharged while being rotated toward the center side by the inner vanes 12, so that the exhaust air can be transferred more strongly, thereby maximizing the circulation efficiency of the indoor air It will be possible to do.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Accordingly, such modifications or variations are intended to fall within the scope of the appended claims.
