FIG. 6 is a cross-sectional view illustrating a fan installed on a ceiling using reflection of air according to a preferred embodiment of the present invention.

1 to 6, an electric fan using reflection of air according to the present invention includes a support cover 10, a rotation shaft 20, a guide cover 30, an intake fan 40 and a protective cover 50 do.

First, the support cover 10 is provided with a motor 11 therein, and the support portion 12 is coupled to the outer surface thereof.

At this time, the front of the support cover 10 is opened and a motor 11 is provided therein. The motor 11 may be operated by being supplied with external power or may be operated by receiving power from a power supply unit provided inside the support cover 10. [

The supporting portion 12 coupled to the outer surface of the supporting cover 10 may have a structure capable of adjusting the height or angle of the supporting cover 10 and is a known matter so that detailed description of the structure is omitted .

On the outer surface of the support cover 10, a projection 36 is formed. The protrusion 36 is engaged with the support portion 12, and a guide groove is formed in one direction. That is, as the projection 36 of the support cover 10 is guided along the guide groove 13 to one side, it is possible to rotate left or right or up and down.

The rotary shaft 20 is coupled to the motor 11 so as to be projected forward of the guide cover 30 to be described later and rotated.

In addition, a wire may be provided so that the center of the rotating shaft 20 penetrates to transmit power, and does not rotate together with the rotating shaft 20. Further, an illumination may be provided at the end of the electric wire. At this time, the illumination may be provided in the intake hole 53, which will be described later, and may be provided at the front end of the rotation shaft 20. Accordingly, when the fan of the present invention operates using the reflection of the air, it is possible to easily grasp whether the lighting works together with the operation of the fan, or to use indirect lighting even when the fan does not operate.

The guide cover 30 is provided in front of the support cover 10 and is open at the front. That is, the guide cover 30 has a structure for guiding and reflecting the sucked outside air so that the suction fan 40, which will be described later, sucks the outside air from the front and can discharge the sucked outside air back to the front.

4 to 6, the guide cover 30 is provided with a motor 11 therein and is open at the front. Further, a support portion 12 for connecting the guide cover 30 to the ceiling is provided.

The guide cover 30 includes the projecting portion 31 and the reflecting portion 33.

The projecting portion 31 is formed with a through hole 32 through which the central portion of the guide cover 30 protrudes forward and through which the rotation shaft 20 passes.

The outer side of the projecting portion 31 is formed rearwardly inward to guide the outside air from the central portion to the outside, and reflects it forward.

Particularly, the reflecting portion 33 is formed by inserting backward between the projecting portion 31 and the outer end of the reflecting portion 33, and the concave groove 34 whose inner side is curved is formed. At this time, the innermost radius of the concave groove 34 from the central portion may be larger than the outermost radius of the intake fan 40 described later from the central portion, but is not limited thereto.

The concave groove 34 may have a predetermined curvature so as to smoothly guide the outside air, but is not limited thereto.

Accordingly, the outside air is guided to the discharge passage 51 along the inner circumferential surface of the concave groove 34 when it is sucked into the inside of the reflecting portion 33, and is reflected forward.

In other words, a fan using the reflection of air according to the present invention, instead of a method of sucking outside air from behind in the same manner as a conventional fan, is used in which a front air is sucked in, .

Therefore, the fan using the reflection of air according to the present invention can be used in a closed space in the rear part, that is, the rear side of the support cover 10, in particular, at a position such as a wall surface or a ceiling, , It is possible to install without a separate support part (12) according to the installation, and the installation can be made easier.

On the other hand, on the inner circumferential surface of the concave groove 34, a rotation guide portion for guiding the outside air in the clockwise or counterclockwise direction can be formed.

The rotation guide portion may be formed by a groove which is inserted into the inside or a projection which protrudes outward. The rotation guide portion may be curved or inclined in one direction to rotate the outside air.

The suction fan 40 is coupled to the end of the rotary shaft 20 and rotated. At this time, the suction fan 40 sucks the outside air into the guide cover 30 from the front of the guide cover 30. Then, the intake fan 40 can suck outside air and increase the wind speed of outside air.

In addition, a plurality of lights may be provided on the rear side of the intake fan 40, and the illumination is operated by a power source supplied from the outside. At this time, when the illumination is activated, the light of the illumination is reflected on the inner circumferential surface of the guide cover 30 and is discharged to the discharge path 51. Accordingly, the fan using the reflection of the air can be utilized as illumination or indirect illumination through the illumination.

The protective cover 50 is provided outside the suction fan 40 such that a discharge passage 51 is formed between the inner surface of the guide cover 30 and the suction fan 40.

That is, the outside air sucked into the inside of the guide cover 30 by the suction fan 40 is guided to the inside of the guide cover 30 along the inner side surface of the guide cover 30, And is discharged to the front of the guide cover 30 through the guide cover 30.

The outer end of the reflector 33 is formed with an extended portion 35 that extends further forward than the protruding portion 31 so that the protective cover 50 and the suction fan 40 are disposed inside the guide cover 30 do. At this time, the extended portion 35 has a predetermined radius from the center portion at the end of the concave groove 34 having a predetermined curvature and is formed to extend forward.

This is because the outside air discharged to the discharge path 51 goes straight ahead from the outside of the protective cover 50 to be discharged, and at the same time, it is collected at the center toward the front.

Accordingly, the fan using the reflection of the air according to the present invention increases the wind speed by the intake fan 40 and concentrates the external air to be drawn into the discharge passage 51 having a constant width, and discharges the air to a higher wind speed, Strong winds can be generated, and since the outside air is drawn in from the center portion, the discharged outside air is concentrated toward the center portion, which can cause strong winds to a long distance.

The protection cover 50 described above includes the intake portion 52, the protection portion 54, and the engagement portion 57.

The intake portion 52 is formed with an intake hole 53 through which external air is sucked in front of the intake fan 40. At this time, the cross-sectional area of the intake hole 53 may be smaller than the cross-sectional area of the exhaust passage 51, but is not limited thereto. That is, the intake air is compressed by the exhaust passage 51 and can be smoothly discharged at a high speed, and the generation of noise can be minimized.

The intake hole 53 may be formed as a small hole so that a finger, a chopstick, or the like may not flow into the intake hole 40 so as to protect the front of the intake fan 40.

The protective portion 54 extends rearward of the end of the intake portion 52 to cover the outside of the intake fan 40. [ At this time, it is preferable that the protective portion 54 protects the outside of the intake fan 40 and extends to the inner side surface of the guide cover 30.

This is to prevent the user from directly touching the fan when the user inserts a finger, chopstick or the like into the discharge path 51.

The protector 54 is formed with an exhaust hole 55 through which the outside air sucked by the air intake hole 53 is transferred from the inside of the guide cover 30 to the exhaust passage 51.

In addition, the discharge holes 55 are formed through the circumferential direction of the outer peripheral surface of the protective portion 54, and a plurality of the discharge holes 55 are stacked in a front-back direction. This is because even if a finger or chopstick flows into the discharge hole 55, movement of the discharge hole 55 in the circumferential direction can not be prevented, and movement of the finger or chopstick in the back and forth direction is prevented, It is possible to prevent and protect the suction fan 40 from breakage or injury of the finger.

The protective portion 54 is formed with an inclined portion 56 having a smaller radius from the front to the back.

At this time, the inclined portion 56 is configured to guide the outside air (hereinafter referred to as "outside outside air"), which is drawn between the inside end of the inclined portion 56 and the outermost radius of the intake fan 40, So that it can be guided to the innermost side of the part (33). In addition, the inner end radius of the inclined portion 56 is formed to be larger than the innermost radius of the concave groove 34.

Accordingly, the outer outside air joins with the outside air (hereinafter referred to as "inside outside air") that is drawn in between the inner end and the center of the inclined portion 56 that is already guided by the reflecting portion 33, ). At this time, the outside outside air and the inside outside air are compressed while being merged and discharged to the discharge hole 55 at a high speed.

In particular, due to the inclined portion 56 of the protective portion 54, the guide direction of the external air sucked into the reflective portion 33 can be maintained at the center outward, and the radius of the guide cover 30 can be minimized .

That is, when the innermost radius of the concave groove 34, which is the innermost portion of the reflecting portion 33, is larger than the outermost radius of the intake fan 40, the outside air sucked from the intake fan 40 flows into the concave groove 33 of the reflecting portion 33 The curvature of the concave groove 34 having a predetermined curvature is increased so that the guide of the outside air can be smoothly guided by the guide groove 34. However, Width and radius can be large. In this case, as shown in FIG. 4 to FIG. 6, it may be suitable for a case where a ceiling with a limited space is installed.

Conversely, if the innermost radius of the concave groove 34, which is the innermost portion of the reflecting portion 33, is smaller than the outermost radius of the suction fan 40, the phenomenon that the outside outside air is guided from the outside to the center of the concave groove 34 And the air velocity of the outside air discharged by the vortex phenomenon in the concave groove 34 becomes small.

Thus, by forming the reflecting portion 33 in the protecting portion 54, the outside outside air is guided to the innermost side of the concave groove 34 along the reflecting portion 33, merged with the inside outside air, As shown in FIG. 1, the front and rear widths and radii can be optimized when the fan of the present invention is made of a stand type, as shown in FIG.

At this time, the air amount of the inside outside air is larger than the air amount of the outside outside air, and the wind speed of the inside outside air accelerated by the intake fan 40 is larger than the wind speed of the outside outside air, And can be smoothly discharged to the discharge hole 55 at the highest wind speed.

The cross sectional area of the concave groove 34 or the inner circumferential face of the concave groove 34 and the cross sectional area of the protective portion 54 becomes smaller by the protective portion 54 from the front toward the rear, The air can be compressed when it joins, and the wind speed and wind force of the compressed outside air can be larger.

Referring to FIG. 5, an illumination 60 may be provided inside the protection unit 54, or an illumination 60 may be provided outside the protection unit 54, as shown in FIG.

The engaging portion 57 is formed at the end of the protective portion 54 and is engaged with the inner surface of the guide cover 30. [

At this time, the engaging portion 57 may be a protrusion, may be coupled to a groove formed on the inner surface of the guide cover 30, or may be coupled with a screw coupling method.

The width of the discharge path 51 is formed between the inner circumferential surface of the guide cover 30 and the outer circumferential surface of the protective portion 54 and can be narrowed toward the front side by the inclined portion 56 to be described later.

The outside air discharged to the discharge hole 55 is compressed by the discharge passage 51 having a narrow width and can be discharged to the outside. The wind speed and the wind force are further improved, have.

In the above description, 'radius' represents the radius from the central axis of the center of the guide cover 30. [
