BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to an air flow switching apparatus, and more particularly, to an air flow switching apparatus in which a flow of an airflow generated through a rotating unit rotating in one direction is changed to an opposite area of openings of passages formed on both outer peripheral sides of a rotating unit, The present invention relates to an air flow switching device which is capable of easily switching an air flow.

Axial-flow fans are widely used in various fields such as general machinery industry, shipbuilding / offshore field, and onshore plant.

The axial flow fan is characterized in that the flow direction of the air is parallel to the rotation axis of the fan, and the types thereof include a propeller fan, a tubular axial flow fan, and a vane-type axial flow fan.

1, a conventional blower includes a fan 200 that is rotated by a motor 100 connected to the rear and feeds an air stream in an axial direction, a frame 300 installed around the fan 200 to guide the flow of air, And a motor support frame 400 coupled to the motor 100 and the frame 300 to support the motor 100, so that ventilation can be performed by exhausting air in the room where the blower is installed or by sucking air in the outside air.

However, since the airflow guiding portion 301 of the frame protrudes only on one side of the front or rear of the fan 200 so that the flow of the airflow is guided to either side only, any one of the intake air or the exhaust air Method can be taken efficiently.

Therefore, after the blower is installed at a certain position, only one method has to be taken and used because the opposite method is used to reverse the rotation of the fan, It can not be shown.

Therefore, when changing the mode of use of the blower, it is difficult and inconvenient to install the blower in a direction opposite to the previously installed direction after dismantling the installed blower.

As a result, in order to circulate air in the room, a suction fan and an exhaust fan must be separately provided, and power must be separately supplied to each fan.

The operation of the airflow switching device 10 of the present invention having the above structure is as follows.

The air flow switching device 10 of the present invention can be installed in various industrial fields, but the present invention is applied to the field of air supply and exhaust of an air conditioner.

The opening hole 140 of the first duct 100a is connected to a duct for supplying outdoor air to the room and the opening hole 140 of the second duct 100b is connected to a duct for supplying indoor air to the outside .

The opening hole 140 of the first duct 100a is connected to the outdoor duct 11 for supplying outdoor air to the room and the opening hole 140 of the second duct 100b is connected to the indoor duct 12 for supplying and exhausting the indoor air to the outside .

In the present invention, the airflow switching device 10 rotates the rotating part 200 through the motor 230 to generate an airflow.

Here, the rotary part 200 is rotated in only one direction.

6 and 7, when the outdoor air is supplied to the room through the air flow switching device 10 of the present invention, the pair of diverters are moved in the direction of the outdoor duct 11 so that the internal area of the first channel 131 is And the internal area of the second passage 132 is formed to be wide.

That is, the open internal area of the second passage 132 of the pair of passages is widened through the diaphragm 310. The diaphragm 310 is moved so that the open internal area of the opposite first passage 131 is relatively narrowed.

11, a vortex is generated in the first passage 131 near the outer periphery of the rotary part 200 of the pair of the diaphragms 310 due to the collision of the end of the diaphragm 310 with the airflow generated through the blade bending of the rotary part 200, The flow of the airflow is controlled by the one passage 131.

In contrast, since the second passage 132 has a large internal area, the airflow generated through the blade bending of the rotary part 200 is not collided, and the airflow generated through the rotary part 200 flows into the second passage 132 having a large internal area.

As a result, the airflow generated in the rotary part 200 sucks outdoor air through the opening hole 140 of the second duct 100b and flows through the space of the second duct 100b and the space of the first duct 100a and the opening hole 140 through the second passage 132 Supply outdoor air to the room.

8 and 9, when the air in the room is exhausted through the airflow switching device 10 of the present invention, the pair of diaphragms are moved in the direction of the outdoor duct 11 so that the internal area of the second passage 132 is And the internal area of the first passage 131 is formed to be wide.

That is, through the diaphragm 310, the open internal area of the first passage 131 of the pair of passages is widened. The diaphragm 310 is moved so as to form an open internal area of the opposite second passage 132 to be relatively narrow.

At this time, in the second passage 132 close to the outer periphery of the rotary part 200 of the pair of diaphragms 310, the air current generated through the blade bending of the rotary part 200 collides with the end of the diaphragm 310 and vortexes are generated, It is enforced.

In contrast, the first passage 131 is formed to have a large internal area, so that the airflow generated through the blade bending of the rotary part 200 is not collided, and the airflow generated through the rotary part 200 flows into the first passage 131 having a large internal area.

As a result, the airflow generated in the rotary part 200 sucks the room air through the opening hole 140 of the first duct 100a and flows through the space of the second duct 100b and the space of the second duct 100b and the opening hole 140 through the second passage 132 Indoor air is exhausted outdoors.

Here, the inner area of the first passage 131 and the second passage 132 refers to the volume of the space having the width and height between the outer periphery of the rotary part 200 and the ends of the pair of diaphragms 310. [

Further, in the present invention, the open areas of the first passage 131 and the second passage 132 are relatively wide or narrow, but the inner area of the first passage 131 or the second passage 132 is open or closed through the partition 310 It can also mean that it is closed.

The air flow switching device of the present invention configured as described above can generate airflow through one-direction rotation of the rotary part 200 and change the open areas of the passages formed on both outer sides of the rotary part 200 to mutually opposite areas, .
