DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a front safety net of an electric fan according to the present invention will be described in detail with reference to the accompanying drawings.

In the present invention, the front safety net means that the front safety net is connected to the rear safety net provided on the rear side of the fan blades.

The present invention can be installed in the rear safety net of a fan in use, which is excellent in practicality and economy, and can be fastened with the rear safety net quickly and easily. The wind formed during the rotation of the blade passes through the outer guide, It is a technical feature that when passing out of the safety net, winds are guided to cause vortexes of plural spiral protections to increase the wind volume and wind speed.

2 shows a front safety net according to the present invention.

The front safety net 100 is coupled to the rear safety net 4 of the fan through the first and second fixing clips to be described later and includes an outer guide 110, (130).

The outer guide 110 is formed as a ring body having a predetermined width and an open front and a rear surface to improve the efficiency of the fan by ensuring the straightness of the wind generated when the wing rotates. (Forward) to the other (rear) in order to secure the straightness of the wind and improve the efficiency of the fan.

The reason why the outer guide 110 is formed in a form (funnel shape) that gradually becomes narrower from one side to the other is to use Bernoulli's theorem. According to this, when the same amount of wind (fluid) , The pressure of the passing wind is lowered while the velocity of the wind (flow velocity) increases as the cross-sectional area of the guide becomes smaller.

The protective fins 120 are formed on the front surface of the outer guide 110 so as to protect the wings 1 and are formed in a spiral shape so that the wind formed through the wings can vortex out, . One end of the protective fence 120 is fixed to the outer guide 110 and the other end is fixed to the protective fence fixing plate 130.

A conventional conventional fan is a fan that winds in the form of a spiral when the wing is rotated. The wind is hit by a straight protective fence provided at the front of the wing, resulting in frictional force, which reduces wind speed and reduces airflow. . The shape of the protector 120 may be formed in a spiral shape so that the straightness and the rotational force of the blowing wind can be maintained as it is, so that the efficiency of the fan can be further improved.

Meanwhile, the protective clothing 120 according to the present invention is gradually thickened from the rear to the front, so that the inner diameter of the passage through which the wind is discharged is gradually narrowed, so that the wind is not scattered, Can be expected. The reason why the protective fence 120 is formed to be gradually thicker from the rear to the front is to use the Bernoulli's theorem in order to reduce frictional resistance when the wind passes, do.

The protective securing plate 130 is provided on the front surface of the outer guide 110 so as to be located on the same line as the central axis 2 of the vane 1.

As shown in FIG. 1, a conventional protection fan 130 'is formed at the center of the front of the conventional fan, and is formed of metal or synthetic resin. A plurality of protective fins 120 'are provided in the radial direction so as to protect the wing of the fan and to prevent an accident that infants and young children put their fingers in and injure them.

The protection fence 120 'provided in the front safety net of the conventional fan can simply protect the blades of the fan, prevent safety accidents of young children, and allow the wind generated during rotation of the fan to spread out widely However, it was not provided to improve the efficiency of the fan as in the case of the protective clothing of the present invention.

The protective fence 120 according to the present invention protects the blades of the fan, prevents safety accidents of young children, and guides the wind formed at the rotation of the blades to vortex in a spiral shape to escape to the outside. The wind formed during the rotation of the wing passes through the outer guide to improve the straightness and to guide the wind so as to cause vortexes of a plurality of spirals when the windshield exits the front safety net so that the wind amount and wind speed are improved and the efficiency is remarkably improved .

4, a front side of the front safety net 100 is formed with a diameter smaller than that of the outer guide 100, and a band-shaped partitioning guide 140 connecting the protective fingers is disposed in front and rear As shown in FIG.

The wind from the protective upright fixing plate to the split guide is referred to as a first wind outlet, and from the split guide to the outer guide is regarded as a second wind outlet, the wind on the front side of the wing during the rotation of the wing is discharged through the first wind outlet, The wind between the inner peripheral surface of the outer guide and the end of the outer guide is discharged through the second wind outlet.

The front safety net of the conventional fan is separated from the protection fence and the protection fence by a predetermined distance so that the wind is released through the space between the protection fence and the protection fence. The wind on the front side of the blades secures straightness through the rotational force of the blades, However, there is a problem that the wind between the end portion of the blade and the inner circumferential surface of the front safety net has no straightness and is scattered in the radial direction, thereby causing loss.

The dividing guide according to the present invention is formed so as to become gradually thicker from the rear toward the front (see FIG. 3) so that the inner diameter of the passage through which the wind is discharged becomes gradually narrowed, so that the wind between the end of the blade and the inner circumferential surface of the outer guide But it is guided to come out in the form of a straight line.

The reason why the dividing guide 140 is formed to be gradually thicker from the rear to the front is that the frictional resistance is reduced when the wind passes and the Bernoulli's theorem is used as in the case of the outer guide. do.

Next, in the present invention, the guard-preventing fixing plate 130 is extended from the rear edge to a predetermined length by a guide 131 for preventing turbulence, securing the straightness of the wind generated when the blade is rotated, And to reduce the noise due to the occurrence of turbulence.

FIG. 5A is a view for explaining the principle of preventing turbulence from being formed in front of a blade of the turbulence prevention guide according to the present invention, FIG. 5B is a view for explaining the principle of forming turbulence in front of a conventional fan blade, .

The blade 1 of the fan is formed with a central shaft 2 through which the rotation shaft of the motor is inserted and the fixing cap 3 is coupled to the end of the rotation shaft so that the blade is not separated from the rotation shaft of the motor. Conventionally, at the front center of the front safety net of the conventional fan, a circular protective plate 130 'made of a metal or a synthetic resin material and connected to an end of the protective fence to protect the wing and the fixed cap is provided. However, in such a conventional fan, when the blades are rotated, the protective plate located in front of the blades interferes with the movement of the wind, thereby forming a turbulent flow on the rear surface of the protection plate, that is, in front of the blades. Further, a space is formed between the wing and the front safety net, and the wind generated by the wing collides with the rear surface of the protection plate, thereby generating noise.

The present invention reduces the spacing space between the turbulence prevention guide 131 and the wing so that the wind generated during the rotation of the wing smoothly moves outward along the guide for preventing turbulence, thereby preventing formation of turbulence in front of the wing It is possible to prevent the efficiency of the fan and the generation of noise.

Next, at one side edge of the outer guide 110 according to the present invention, the rear safety net rim is seated to form a separation preventing chin 150 for preventing the rear safety net from being separated.

Referring to FIG. 3, the release-preventing jaw 150 is formed in a shape of '┓' -shaped to support and support the rim 5 of the rear safety net. In the present invention, the rim of the rear- So that the front safety net and the rear safety net are engaged with each other and then joined through the following fixing clip 200.

Here, the separation protector 150 may be vertically and continuously arranged in a stepwise manner so that the separation protector 150 can be fixedly coupled without being affected by the diameter of the rear safety net of the fan, which is being used in the past.

At present, there is a slight difference in the diameter of the rear safety net depending on the manufacturer of the fan that is being used in homes and businesses. However, if the diameter of the front safety net is shorter than the diameter of the rear safety net of the fan in use, the rear safety net can not be seated on the separation preventing side, Since the spacing space is formed between the rims, the front safety net may be shaken when using, resulting in noise and safety accidents.

6, the present invention is characterized in that the first fastening holes 152, which are formed in the shape of "┓" from the end of the separation preventing jaw and have threads on the inner circumferential surface thereof, A fastening part 210 formed with a first fastening hole 151 and a second fastening hole 211 at a position corresponding to the first fastening hole 152 and seated in the fastening clip seating part 151, And a first fixing clip 200 formed of a tight fitting part 220 which is formed at an end portion of the rear safety net and closely contacts the rim 5 of the rear safety net to fix the rear safety net.

Here, the first fastening holes 152 may be formed in a plurality of ways so as to further increase the binding force between the first fastening clip 200 and the fastening clip receiving portion 151.

The release bout 150 and the fastening clip seating part 151 and the first fastening clip 200 prevent the fastening part from being exposed during fastening of the front safety net 100 and the rear safety net 4, So that it can be fastened.

When the front safety net 100 and the rear safety net 4 are fastened to each other, the front safety net 100 is first engaged with the rear safety net 4 so that the rim 5 of the rear safety net is seated on the separation preventing net 150.

Next, the first fixing clip 200 is positioned so that the second fixing hole 211 of the first fixing clip 200 corresponds to the first fixing hole 152 of the fixing clip seating portion 151. The end of the tight fitting part 220 is naturally adhered to the rim 5 of the rear safety net.

Thereafter, the first fixing clip 200 is fixed to the fixing clip seating portion 151 through the bolts B to fix the front safety net 100 and the rear safety net 4.

The conventional fan has a drawback in that the bracket or the fixing member formed with the bolt hole is exposed to the outside so that the front safety net and the rear safety net can be fixed. In addition, since such brackets (or fixing pieces) are exposed to the outside, they may be damaged due to external impact or other factors during use or storage.

Since the first fixing clip 200 is fixed to the inside of the front safety net, it can be prevented from being exposed to the outside, and the first fixing clip can be prevented from being damaged due to an external impact or other factors.

One or more brackets 170 may be formed on the outer circumference of the outer guide to form a fastening hole 171. The outer guide may include a plurality of ribs 170, And a second fixing clip 300 formed with a flange insertion hole 310 and a bolt insertion hole 320 in which the rim 5 of the rear safety net is inserted and tightly bolted to the bracket, .

The rear guide 160 may have a predetermined cutout 161 at a position where the bracket is formed.

The rear guide 160 guides the air introduced from the rear of the fan when the blade is rotated to improve the straightness. When the rim of the rear safety net is in close contact with the separation preventing jaw, the end of the rear guide 160 surrounds the protection fence provided in the rear safety net 4. Therefore, the air behind the fan is naturally guided, Can be smoothly introduced into the rear safety net.

The rear guide 160 may extend in the form of a straight line from the end of the departure-avoiding jaw. However, as the wind flowing from the rear of the fan passes through the rear guide, the rearward guide 160 gradually widens toward the rear so that the pressure decreases and the speed increases. Or may be formed in a losing form.

The fastening hole 171 formed in the bracket 170 is formed to have a predetermined diameter so that the bolt B can be inserted. Even if the diameter of the rear safety net of the conventional fan is different from the diameter of the front safety net, And may be formed in the shape of an intestinal hole having a predetermined length so as to be possible.

The edge fixing groove 310 is formed to have a width corresponding to the edge 5 of the rear safety net. The second fixing clip 300 has a strength to prevent breakage during bolting, It is preferably formed of a lightweight material.

A method for connecting the front safety net 100 and the rear safety net 4 according to the present invention through the second securing clip 300 is as follows.

First, the rim 5 of the rear safety net is brought into close contact with the separation preventing jaw 150 so that the front safety net 100 and the rear safety net 4 mesh with each other.

Next, the second fixing clip 300 is brought into close contact with the bracket 170 in the cutout 161, and then fixed with the bolts B.

When the bolt B is gradually tightened, the rim 5 of the rear safety net naturally inserts into the rim insertion slot 310 to support the rear safety net, and the front safety net and the rear safety net are fixedly coupled by tightly tightening the bolt .

Since the front safety net of the fan according to the present invention as described above can be combined with the rear safety net of the fan that is used in the past, it is excellent in practicality and economy, is easy to be fastened to the rear safety net, So that the wind can be guided to cause the vortexes of the spiral guards to generate a vortex when the windshield is passed through the front safety net and the airflow and the wind speed can be increased. There is a remarkable advantage that it is possible to reduce the loss of wind and improve the efficiency because the straightness is improved while passing through.
