Description

Air flow amplifier

More specifically, the present invention relates to an airflow amplifying apparatus, and more particularly, to an airflow amplifying apparatus that rotates counterclockwise rotating means disposed opposite to each other in two rows so as to have an effect of increasing an effective airflow distance with an increase in lifting force of an airflow, To an air space amplifying device which communicates with an external space to improve air stream generating efficiency of the rotating means.

Generally, a household air flow generating device that provides convenience of living using air flow is applied to an electric fan, a ceiling fan, a kitchen hood, a fan, and an air conditioner system.

First, fans and ceiling fans typically include a set of vanes or vanes mounted to rotate about an axis, and a drive to rotate the set of vanes to create an air flow. A "wind chill" or breeze is generated by the movement and circulation of the air flow, which results in the user having a cooling effect as heat is dissipated through convection and evaporation.

The fans are classified according to the type, and the devices installed in the ceiling are usually called ceiling fans.

The ceiling fan is installed in a ventilator for ventilating the room, an indoor fan, or a ceiling to induce a flow of air.

The ceiling fan is composed of a ceiling fan fixed to a frame fixed to the ceiling and rotated by a motor shaft, and the ceiling fan rotates by the rotation of the motor to blow air in the room, thereby lowering the temperature.

However, since the ventilator of the related art is generally installed at a high position or a corner where the inside air is not reachable by people because the inside air is generally higher than the outside air, the ventilator is operated for 24 hours rather than the specific time So that the service life is shortened by unnecessarily operating the ventilator and there is a problem that the room air is unnecessarily cooled when the temperature is required to be maintained by continuous infusion of outside air.

In addition, the kitchen hood has a function of reversing the principle of a fan and sucking smoke, steam, and smell generated when cooking food, and discharging it to the outside.

Such a kitchen hood typically sucks air contaminated by smoke, water vapor, and odor generated from a cooking container by a fan (not shown) installed therein and supplies the air to the outside through a duct (not shown) connected to the outside And discharging it.

However, since smoke, water vapor, and smell generated when cooking various foods are spread widely to the kitchen rather than vertically rising from the cooking vessel, the contaminated air spreading widely through the conventional fixed kitchen hood can not be efficiently discharged to the outside There was a problem.

In other words, since a conventional kitchen hood is simply installed in a fixed state in a sink, the distance between the kitchen hood and the cooking container raised on the gas range is far away, so that only contaminated air spread near the kitchen hood is discharged outside, The contaminated air diffused widely from the cooking vessel can not be discharged to the outside at all. Even if the kitchen hood is operated for a long time, the contaminated air diffused widely from the cooking vessel can not be discharged to the outside at all, There is a problem that the smell of food always remains in the living room and the like, which gives an uncomfortable feeling.

Further, since the distance between the kitchen hood and the gas range is large, a large capacity of a rotary motor (not shown) for operating a fan (not shown) of the kitchen hood causes a very large noise when operating the kitchen hood .

The ventilator is a device for evacuating the inside air to the outside and ventilating it, and is widely installed in a factory, a restaurant, a building, a parking lot, a bathroom, a barn, and the like.

As shown in FIG. 5, the conventional ventilator includes a housing space 11 into which room air flows, a casing scroll 10 having a guide surface 12 and a discharge port 13 for guiding the introduced air to the outside, A motor 20, a rotating member 30 mounted on the rotating shaft 21 of the driving motor and receiving and discharging indoor air while being rotated by receiving the rotating force of the driving motor, a protective lid 40 for protecting the rotating member, And a grill 50 formed with a passage 51 through which the gas is moved.

Particularly, in the conventional ventilator, a wing 31 of the rotary member 30 uses a forward vane formed by bending toward the rotational direction of the rotary member due to the drive motor 20. [

Accordingly, the conventional rotary member 30 inflows indoor air and discharges it to the discharge port 13 while enclosing it.

However, in the conventional ventilator, since the forward collar 31 of the rotary member 30 only rotates the wind, the efficiency is lowered and the noise is increased.

That is, the wind amount and the wind pressure structure due to the rotation of the turning collar 31 do not match the reality, and the power of the drive motor 20 is also limited to a small, low capacity.

More specifically, when a typical collar is used, the wind pressure is increased while the efficiency according to wind pressure is lowered. Therefore, in order to generate a certain amount of airflow, the rotating member must be rotated at a high speed.

In addition, when the turning collar is rotated, lift resistance is generated and the wind power without wind resistance is discharged to the outside due to moving air to the outlet 13 while surrounding the air in the room sucked by the forward collar 31. Therefore, Thereby deteriorating the efficiency of the apparatus.

Therefore, there is a problem that the noise increases at high speed.

First, in the drawings, it is noted that the same components or parts are denoted by the same reference numerals as possible. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted so as to avoid obscuring the subject matter of the present invention.

First, as shown in FIGS. 1 to 5, the first embodiment of the airflow amplifying apparatus of the present invention comprises a case 100 and a rotating unit 200.

The case 100 is installed such that the upper surface 110 and the lower surface 120 are opposed to each other with upper and lower gaps therebetween. The airflow guiding walls 140 having slopes on both sides of the space between the upper surface 110 and the lower surface 120 are symmetrically arranged, A guide space 150 is formed.

The case 100 includes a flat plate having a top surface 110 and a bottom surface 120 having a flat surface.

The upper surface 110 and the lower surface 120 are vertically spaced from each other.

The airflow guiding wall 140 is vertically provided on both sides between the upper surface 110 and the lower surface 120 so that the case 100 has a frame shape through the upper surface 110 and the lower surface 120 and the airflow guiding wall 140, A guide space 150 opened laterally is formed.

At this time, the airflow guiding wall 140 is formed on the upper surface 110 and the lower surface 120 except for the space where the rotating part 200 is to be installed, and a guiding surface 141 which is inclinedly protruded inward of the guiding space 150 is formed, A guide space 150 is formed between the guide space 150 and the guide space 150 so that the airflow generated through the rotation of the rotation unit 200 flows from the entrance to the exit of the guide space 150 while drawing outside air outside the guide space 150 to join the airflow, Respectively.

That is, the air flow guiding wall 140 is installed from the middle portion to the other side of the guide space 150 between the upper surface 110 and the lower surface 120, and the rotary portion 200 is installed at the side of the guide space 150.

Here, the rotation unit 200 is provided with rotation means 210 on both sides of the entrance of the guide space 150, and rotates mutually through the motor 160 to flow air into the guide space 150.

In particular, the rotating means 210 is formed with a plurality of blades (not shown) radially in the outer periphery of a shaft (not shown) having a length.

(Not shown) of the motor 160 and a shaft (not marked) of the rotating means 210 are connected to each other by a direct power method so that the wing is rotated by the rotational force generated by the motor 160, .

Here, a controller 170 for determining the number of revolutions of the motor 160 is installed on the upper surface.

Specifically, the rotating means 210 arranged to face each other in two rows are rotated in mutually opposite directions to increase the effective blowing distance according to the increase in lift of the airflow, and the circumference of the rotating means 210 communicates with the outer space, Thereby improving the airflow generation efficiency of the fuel cell.

Here, by making the periphery of the rotating means 210 communicate with the outer space, more effective airflow can be generated.

Particularly, the mesh 180 may be installed at a portion where the periphery of the rotating means 210 is exposed to the external space.

The airflow generated through the rotating means 210 installed as described above causes a pressure change along the guide surface 141 to be described later so as to have an improved air velocity and an air flow rate.

The guide surface 141 includes a first guide surface 142 positioned in front of the rotation portion 200 and inclined in the direction of the guide space 150, a second guide surface 142 formed to be inclined in the sidewall direction, in contact with the first guide surface 142, And a third guide surface 144 which is joined to the second guide surface 143 and has an angle larger than the angle of the second guide surface 143.

An airflow is generated through the rotation part 200 and flows in the guide space 150 of the second guide surface 143 through the first guide surface 142 when the air flows in the exit direction from the entrance of the guide space 150.

At this time, the first guide surface 142 and the second guide surface 143 have different inclination angles to reduce the volume of the guide space 150 of the second guide surface 143 from the guide space 150 of the first guide surface 142 to change the air pressure of the airflow, Air volume.

The second guide surface 143 and the third guide surface 144 are inclined at different angles to increase the volume of the guide space 150 of the third guide surface 144 from the guide space 150 of the second guide surface 143 to change the air pressure of the airflow, Air volume.

That is, the air pressure is lowered on the guide space 150 side of the first guide surface 142 having a faster air velocity, and the air pressure in the guide space 150 of the second guide surface 143 is relatively increased.

As a result, the force of the air acts as a low pressure in the high pressure, so that air having a high velocity passing through the guide space 150 passes through the outside air to form a constant and strong airflow, thereby generating wind.

Thus, the airflow amplifying apparatus 10 includes the rotating unit 200, which rotates the rotating means 210 disposed opposite to each other in two rows in opposite directions to increase the effective airflow distance as the lift of the airflow increases, There is an effect that the air stream generating efficiency of the rotating means 210 is improved by communicating with the external space.

The airflow amplifying apparatus 10 is installed so as to face the rotating means 210 in two rows and then rotates in the opposite direction. The airflow generated by the two rotating means 210 flows into the inclined guide space 150 formed between the pair of rotating means 210 There is an effect that airflow and wind speed are increased by drawing air outside the guide space 150 and joining the airflow.

Further, the airflow amplifying apparatus 10 has the effect of making the airflow pressure change through the multi-step guide surface 141 inclined by the airflow flowing into the guide space 150, thereby doubling the improved wind speed and airflow.

In addition, in the configurations of the case 100 and the rotation unit 200 described in the first embodiment, the number of rotations of the pair of rotation means 210 may be differently applied through the motor 160.

This is because the number of revolutions of the rotating means 210 located on the other side of the rotating means 210 located on one side of the pair of rotating means 210 is increased and the number of revolutions of the rotating means 210 is applied differently, .

As shown in Figs. 6 to 9, the second embodiment of the airflow amplifying apparatus of the present invention is as follows.

In the structures of the case 100 and the rotation unit 200 described in the first embodiment, the hinge unit 145 is provided at a connection portion between the first guide surface 142 and the second guide surface 143, and the angle of the pair of second guide surfaces 143 So that the pressure and direction of the guide space 150 can be changed.

That is, the angle of the pair of second guide surfaces 143 can be freely adjusted through the hinge means 145.

In other words, the pair of second guide surfaces 143 with respect to the hinge means 145 may be adjustable in the left or right direction in a horizontal state.

Alternatively, the pair of second guide surfaces 143 with respect to the hinge means 145 may be angled symmetrically with respect to each other to widen or narrow the exit side area of the guide space 150.

Alternatively, the pair of second guide surfaces 143 with respect to the hinge means 145 may be widened or narrowed at the exit side of the guide space 150 while changing the angle in the left or right direction.

Thus, there is an effect that the intensity and direction of the wind can be changed through the angle of the second guide surface 143. [

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 inventions. It will be clear to those who have knowledge of.
