It's technology.

In the air of a closed space or indoor space, the carbon dioxide content increases over time due to the respiration of living things, and the amount of oxygen decreases, interfering with the breathing of living things. Therefore, when many people stay in a small space, such as an office or vehicle, polluted indoor air must be replaced with fresh outdoor air from time to time. At this time, a ventilation device is commonly used.

Most conventionally known ventilation devices consist of a fan unit installed in a roughly square opening formed in the wall to exhaust indoor air to the outdoors, or two ducts connecting the outdoor and indoor spaces, that is, to bring outdoor air into the indoor space. It consists of an air supply duct that supplies air and an exhaust duct that discharges indoor air to the outdoors.

In addition, an air supply fan and an exhaust fan for moving air are separately installed on the air supply duct and the exhaust duct, so that the air supply fan and exhaust fan provided in the air supply duct and the exhaust duct operate simultaneously, thereby blowing fresh outdoor air through the air supply duct. is supplied to the indoor space, and the turbid indoor air is discharged to the outdoors through the exhaust duct to ventilate the indoor space.

To achieve this, each air supply and exhaust duct of the ventilation structure must be constructed, which has the problem of increasing construction costs.

To solve this problem, a technology that enables two-way ventilation, i.e. air supply and exhaust, with only one duct is:

As shown in Figures 3 to 6,

It largely includes a pair of block bodies 31 arranged side by side up and down with a plurality of fluid transport paths inside, and an ultraviolet irradiation module 32 arranged on the fluid transport paths of each block body 31. .

First, each block 31 is

It consists of four plates that are tightly coupled to each other by bolting. They are divided into the first, second, third, and fourth plates in order from left to right, and '31A' and '31B' for each plate. , it is decided to designate the drawing symbols as '31C' and '31D'.

First, the first plate 31A has a circular first left hole 311 that is recessed from the left side to the right, and is recessed from the right side to the left and is interconnected with the first left hole 311 on one side. A circular first light hole 312 connected eccentrically is formed. The first left hole 311 and the first right hole 312 form one first fluid transfer path 313, and this first fluid transfer path 313 is connected to the first plate 31A. A plurality of them are provided in a grid form.

And the second plate (31B) is formed to penetrate left and right to have the same diameter on the same line as the first left hole 311 of the first plate (31A) and is connected to the first light hole 312. 2.

As another example, the second fluid transfer path 314 of the second plate 31B is also connected to the first light hole 312 and has a same diameter on the same line as the first left hole 311. It may be composed of a second left hole 314a and a second right hole 314b connected to the second left hole 314a and eccentrically disposed on the other side and connected to the third left hole 315.

Therefore, outdoor air containing viruses or harmful gases flows into the first left hole 311 and then passes through the second light hole 312, and the air that passes through this time passes through the second left hole 314a. Instead of flowing directly into the second light hole (314b), the air becomes eddy inside and then flows into the second light hole (314b), and the air thus introduced is once again inside the third left hole (315). It is vortexed and then transferred to the fourth fluid transfer path 318 through the third light hole 316.

In the end, as the air passes through the fluid transfer path, it becomes vortexed, becomes stagnant, passes again, becomes vortexed again, becomes stagnant, and then passes again, so the time from when the air is first introduced to when it finally escapes is almost In the same way, it is possible to create conditions for irradiating ultraviolet rays through the ultraviolet irradiation module 32 for a certain period of time.

The ultraviolet irradiation module 32 is

It is placed on the fluid transport path of the block body 31 and is used to irradiate ultraviolet rays to the air transported through the fluid transport path,

The displacement unit 40 is

As shown in Figures 1, 3, and 7 to 12,

When air is supplied to the room by the fan unit 20, the ultraviolet irradiation unit 30 is moved toward the indoor side in the space 11 of the duct body 10 by the supplied wind, and the fan unit 20 ) to guide the ultraviolet irradiation unit 30 to move to the outdoor side in the space 11 of the duct body 10 by the exhausted wind,

Ultimately, when the adjustment bolt 445 is tightened, the middle part of the elastic support 444 descends toward the plate 442, and on the contrary, when it is loosened, the middle part of the elastic support 444 rises toward the opposite side of the plate 442. , Through this, the elastic support force of the elastic support body 444 can be adjusted.

The supporting means 44 of this structure are located at four locations on the inner wall of the space 11 of the duct body 10 adjacent to the four corner areas of the upper block body 31 among each block body 31. ) are preferably provided at each of the blocks 31, and at four locations on the inner wall of the space 11 of the duct body 10 adjacent to the four corner areas of the lower block body 31 among the blocks 31. It is desirable to have it provided.

Therefore, the block body 31 moved by the influence of the wind is maintained in a state elastically supported by the elastic supporter 444, and when the influence of the wind is released, in other words, the operation of the fan unit 20 is stopped. When stopped, it is pushed and moved a certain distance by the restoring force of the elastic support 444.

As shown in FIG. 7, when air is supplied by the fan unit 20, that is, when external air is blown toward the indoor side, the ultraviolet irradiation unit 30 is moved by the wind until it is elastically supported by the supporting means 44. By stopping, it helps to further secure the space between the fan unit 20 and the block body 31 so that the outside air can spread sufficiently and flow into the block body 31.

As shown in Figure 11, on the contrary, when exhausting by the fan unit 20, that is, when blowing the internal air to the outdoor side, the ultraviolet irradiation unit 30 is moved by the wind until it is elastically supported by the supporting means 44. At this time, each block body 31 is rotated 180 degrees by the drive unit 50, which will be described later, and the direction is changed, and then moved and stopped, between the indoor entrance of the duct body 10 and the block body 31. By securing more space, it helps to allow the internal air to spread widely enough to flow into the block body (31).

Meanwhile, the two-way blowing duct structure according to the present invention further includes a driving unit 50 and a controller 60.

The driving unit 50 is

As shown in Figures 1 and 3,

A drive motor 52 having a drive shaft 51 connected to the shaft 41.

It is made including.

At this time, the drive motor 52 is electrically connected to the controller 60.

The controller 60 is

As shown in Figure 7,

It consists of a circuit structure for changing the blowing direction of the fan unit 20 and controlling the driving unit 50 according to the blowing direction.

Ultimately, when the user selects the blowing direction mode using an external switch, etc., this signal is received and the fan unit 20 and the driving unit 50 are controlled.

Therefore, as described above, when the ultraviolet irradiation unit 30 is moved by the wind until it is elastically supported by the supporting means 44 during exhaustion by the fan unit 20, that is, when blowing the internal air to the outdoor side, Each block body (31) is rotated 180 degrees by the drive unit (50) to change direction, move and then stop,

Conversely, even during intake by the fan unit 20, each block body 31 is rotated 180 degrees by the drive unit 50 to change direction.

In this operation, the controller 60 receives an external manipulation signal and controls the fan unit 20 and the driving unit 50.
