Description

Fine dust protection system {Fine Dust Protection System}

The present invention relates to a fine dust blocking and dustproof system, and more particularly, to a fine dust blocking and dustproof system that automatically closes a dust screen installed in an open window by sensing the concentration of outdoor fine dust.

The windows and doors are installed and opened on the wall of the building, allowing the interior and exterior of the building to communicate. The windows and doors are closed airtightly through the window glass, but can be selectively opened to allow ventilation, and even if they are closed, the exterior and interior appear to pass through, eliminating the tightness and making the interior of the building wider. If the window glass is opened during ventilation or in the summer, worms enter and exit the building as the inside and outside of the building are fully communicated. For this reason, insect screens are blocked by using insect screens with fine mesh nets instead of window glass. In addition, in recent years, dust screens for preventing external fine dust from entering the inside of a building as well as an insect screen are used.

Patent Document 1 is to install a window screen slidably with a window on a window frame frame fixed to a building, formed on the inner surface of the frame constituting the window screen so that a thin bar-shaped material can be accommodated A groove extending in the longitudinal direction of the filter element is installed so as to be fitted and broken in a groove, and a net-shaped insect screen and a collection network having opacity are overlapped, but at least the filter element or frame is fixed by fixing a support frame at its edge. It is a window system that has both insect and dust protection functions, which include locking means that are provided on either side and keep the fastening state between them.

Patent document 2 is a fine dust blocking filter for windows installed on a window, consisting of a frame installed on a window frame and a dustproof filter sheet installed inside the frame, the filter sheet is a non-woven or cotton material fibrous sheet, filter sheet Includes a porous adsorbent impregnated with a fibrous material, and the dust-proof filter sheet has a thickness of 1 to 5 mm, and is a fine dust blocking filter for windows having an air permeability of 100㏄ to 400㏄ / ㎠ / sec.

Patent Literature 3 attaches a rubber magnet to the surface that matches the upper, lower, left, and right outer door frames, but overlaps a flexible PCB on one side, an integrated screen, a PCB, a weight and a rechargeable battery, and a bottom pipe with a plate spring mounted on the left and right ends, A screen winding pipe with a built-in motor, a roll screen formed by fastening the upper part of the screen to the screen winding pipe, and the lower pipe being fastened to the lower part of the screen, and attaching magnetic materials to the upper, lower, left, and right front surfaces of the door frame, and attaching the lower magnetic material and the magnetic material of It is a roll screen with a sealing function consisting of the roll screen and a pair by connecting and connecting the wires of the socket to the lower side of the magnetic body and the lower side of the magnetic body on the symmetric side of the one side magnetic body.

Patent Document 4 is a window for blocking fine dust, the window frame; Removable window frames and prefabricated windows including a grate; And a fine dust blocking filter attached to both sides of the prefabricated window, wherein the window frame includes a first outdoor window frame and a second indoor window frame, and a first locking jaw formed in the first window frame and a second window frame. It is a window for blocking fine dust, which includes two locking jaws and is formed in an interlocking structure so that the first and second locking jaws overlap each other.

In general, the dust screen needs to have a very fine mesh mesh size in order to increase the blocking rate of fine dust, so air permeability is low and ventilation efficiency is low. In addition, some anti-vibration screens are opaque, which reduces light and openness. Therefore, it is common to keep the dust-proof screen open on a clear day without fine dust and to block the dust-proof screen on days with many fine dust.

On days when the outside air contains a lot of yellow dust or fine dust, the window should be closed or the dust screen should be closed. However, if both the window and the dust screen are opened and the fine dust concentration increases while going out, there is a problem in that the fine dust is introduced into the building as it is and the indoor air of the building is contaminated with fine dust.

Each of the anti-vibration screen devices 12a, 12b, 12c, and 12d detects the opening / closing state of the window when a screen driving signal is received from the main controller 14, and pulls out the anti-vibration screen when the window is open. When the window is closed, the dust-proof screen is maintained even when the fine dust concentration is high. Each anti-vibration screen device (12a, 12b, 12c, 12d) transmits the opening and closing state information of the window and the input / output state of the anti-vibration screen to the main controller (14). Then, the main controller 14 displays the opening / closing state information of the window corresponding to each dust-proof screen device and the dust-screen input / exit state information on the display unit 15 (or input / output unit).

When the window is opened and the dust screen is pulled out, the window cannot be closed without inserting the dust screen because the dust screen is located indoors rather than the window. In addition, when the fine dust concentration is low, it is necessary to introduce a dust screen. In this case, the user may request to input the corresponding dust screen through the user input unit 13 (or input / output unit). When the user requests to enter the dust screen, the main controller 14 transmits a screen input signal to the corresponding dust screen device, and the dust screen device draws the dust screen. At this time, air is sent to the dust screen to remove fine dust attached to the dust screen.

This anti-vibration screen device is equipped with a frame, a window opening / closing sensor 31 for detecting whether a window is opened, a communication unit 32 for communication with the main controller 14, and a dust-proof screen 22 as a constant flat member. The screen taking-in / out means 34 for entering or entering the interior receiving space of 21a, the air nozzle 37 for sending air, and the air nozzle 37 by turning at an angle to turn the air nozzle 37 Air nozzle turning means (35) for allowing air to be discharged through the lower side or the lower side, an air generating part (36) for generating the air and supplying the air to the air nozzle (37), and the screen entry / exit means (34). By the UV lamp 39 to sterilize the dustproof screen 22 introduced into the accommodation space, the UV driving means 38 for driving the UV lamp 39, the screen drawing in and out means 34 and air It includes a control unit 33 for controlling the nozzle turning means 35, the air generating unit 36 and the UV driving means (38).

Figure 4 shows the inner receiving space and the air nozzle of the water flat member according to the present invention.

The screen take-in / out means 34 is composed of a winding roller 41 of a dust-proof screen and a motor (not shown) for rotating the winding roller 41. The winding roller 41 is located in the inner receiving space of the constant flat member, is formed extending in the same direction as the extending direction of the constant flat member, and is formed in a cylindrical shape having a predetermined diameter. When the take-up roller 41 rotates by the driving force of the motor, the dust screen 22 is wound into the take-up roller 41 while being pulled into the receiving space, or released from the take-up roller 41 while receiving space by the gravity body 23 Is withdrawn out.

An air nozzle 37 extending in the same direction as the take-up roller 41 is mounted on the lower outer side of the constant flat member 21a. The air nozzle 37 rotates at a predetermined angle to send air downward (gravity direction) (see FIG. 4 (A)) or downward downward (vibration screen direction) (see FIG. 4 (B)). ). When the air nozzle 37 sends air in the downward direction, it functions as an air curtain to block external dust from entering the building, and when the air nozzle 37 sends air outward, the function of air cleaning By doing so, the fine dust attached to the dustproof screen 22 is shaken out.

The air nozzle turning means 35 is composed of a turning motor (not shown) and may be provided with a stopper to turn only at a certain angle. In the inner receiving space of the constant flat member 21a, a UV lamp 39 for sterilizing microorganisms and the like attached to the anti-vibration screen and extending in the same direction as the winding roller 41 is accommodated.

Hereinafter, the operation of the fine dust blocking and dustproof system configured as described above will be described.

The dust information acquisition means 11 acquires external fine dust concentration information and provides it to the main controller 14. When the external fine dust concentration exceeds the reference value, the main controller 14 transmits screen driving signals to the four-channel anti-vibration screen devices 12a, 12b, 12c, and 12d, respectively.

Each anti-vibration screen device receives a screen driving signal through the communication unit 32. The control unit 33 receiving the screen driving signal detects whether the window is open / closed through the window opening / closing detection sensor 31. When the window is closed, the anti-vibration screen is maintained in the input state, and the opening / closing state information (closed) and the anti-vibration screen input / output state information (input) of the window are transmitted to the main controller 14 through the communication unit 32. The main controller 14 displays the opening / closing state information of the corresponding window and the dust screen input / exit state information on the display unit 15.

When the window is open, the control unit 33 controls the screen take-out means 34 so that the dust-proof screen is drawn out, and the opening / closing state information (opening) of the window and the dust-proof screen drawing-in state information through the communication unit 32 (Fetch) is transmitted to the main controller 14. The main controller 14 displays the opening / closing state information of the corresponding window and the dust screen input / exit state information on the display unit 15.

By doing this, even if the concentration of fine dust is increased, it is possible to block the fine dust from entering the building through the open window.

Thereafter, when the user wants to close the window or if the fine dust concentration is lower than the reference value, the main controller 14 transmits a screen input signal to the corresponding anti-vibration screen device.

When the screen input signal is received through the communication unit 32, the control unit 33 of the anti-vibration screen device controls the screen input / output means 34 so that the anti-vibration screen 22 is input. That is, the motor of the screen take-out means 34 is driven to rotate the winding roller 41 so that the dust-proof screen 22 is drawn into the inner receiving space of the constant flat member 21a. In addition, the control unit 33 drives the air nozzle turning means 35 to orbit the air nozzle 37 so that the air nozzle 37 faces downwardly outward, and drives the air generating unit 36 to generate air. . The air generated in the air generating unit 36 is sent to the dust-proof screen 22 on the outside outside through the air nozzle 37, whereby fine dust attached to the outside of the dust-proof screen 22 is shaken to the outside. In addition, the control unit 33 controls the UV driving means 38 so that the UV lamp 39 is lit to sterilize the dustproof screen 22 wound around the winding roller 41.

The anti-vibration screen 22 functions to block external dust from entering the building while the window is open. That is, fine dust, microorganisms, and the like are attached to the outer surface of the anti-vibration screen 22. When the dust screen is wound with the winding roller 41 in the state where the fine dust and microorganisms are attached in this way, the outer surface and the inner surface of the dust screen are in contact with the inner surface of the dust screen by being contaminated by the outer surface. Thereafter, the indoor air of the building may be contaminated by the contaminated inner surface. In the present invention, when the dustproof screen 22 is wound up and stored, fine dust attached to the outer surface of the dustproof screen is removed, and UV sterilization treatment is performed so that the dustproof screen 22 is stored.

When the dustproof screen 22 is completely drawn in, the control unit 33 stops the driving of the screen take-out means 34 and drives the air nozzle turning means 35 so that the air nozzle 37 faces downward. By turning (37), the air that has been sent outward downward is sent outward for a certain period of time. When the air nozzle 37 sends air to the lower side like this, it functions like an air curtain and blocks inside and outside the building, so that fine dust outside the building cannot flow into the inside. As such, while the air curtain is functioning, the user can close the window.
