Description

An insect screen that can prevent and remove fine dust indoors {SCREEN THAT CAN BE PREVENTED FROM INFLOWING OF FINE DUST AND CAN REMOVING THE SAME}

The present invention relates to an insect screen capable of preventing and removing fine dust indoors.

In general, it is common to install window frames of various sizes and shapes for indoor ventilation, lighting, and scenery in various buildings. At this time, the window frame is installed at the boundary between the indoor and the outdoor, and an insect screen or glass is installed therein to prevent various flying insects, pests, foreign substances, etc. from entering from the outside. However, the window frame on which the insect screen is installed can prevent the inflow of insects or pests, but there is a problem in that fine dust or pollutants whose size is smaller than the mesh of the insect screen pass through as it is. In addition, the window frame installed with glass can prevent the ingress of insects and pests as well as the inflow of fine dust at the same time, but if you want to circulate air into the room, the window frame must be opened. There is a problem that dust and contaminants pass through as they are.

And, the terms to be described later are terms defined in consideration of functions in the present invention, which may vary according to intentions or customs of users and operators. Therefore, the definition should be made based on the content throughout this specification.

The technical spirit of the present invention is determined by the claims, and the following examples are only one means for efficiently explaining the technical spirit of the present invention to those of ordinary skill in the art to which the present invention belongs.

1 is a conceptual diagram illustrating an insect screen 100 capable of preventing and removing fine dust indoors according to an embodiment of the present invention, and FIG. 2 is a view showing an insect screen 100 according to an embodiment of the present invention.

1 and 2 , the insect screen 100 capable of preventing and removing fine dust indoors includes a generator 10 and an insect screen 100 . Here, the insect screen 100 includes a frame 120 , a conductive network 110 , a current forming unit 130 , and a vibrator 140 . Specifically, the insect screen 100 is formed inside the frame 120 and the frame 120, and provides power to the conductive network 110 and the conductive network 110 composed of thin conductive wires through which current flows so that the current flows. The vibrator ( 140) may be included.

The generator 10 may be a solar (1) photovoltaic generator (10) that stores energy from the sun (1) to generate electricity. For example, energy accumulated during the day may continuously transmit power to the insect screen 100 side. The transmitted power may be consumed when a current flows to the conductive network 110 side by the current forming unit 130 . The power may be output as a voltage of 3V by the current forming unit 130 . Such a voltage is an example, and it is possible to output a voltage that is harmless to the human body. The insect screen 100 formed of the conductive network 110 may collect fine dust in the air.

As electric current flows through the fine dust, heavy metals and the like contained in the fine dust may be adsorbed to the conductive network 110 . For example, Al, As, Be, Ca, Cd, Co, Cr, Cu, Fe, Li, Mg, Mn, Mo, Ni, Pb, Sb, Se, Si, Sr, Ti, Tl, V, Zn It may be a metal component of fine dust, including The current may also prevent access by pests.

On the other hand, the insect screen 100 driven through the generator 10 is generally made continuous collection of power during the day, as well as during the day, it can be continuously driven at night through the surplus power. However, as the time for the heavy metal component of fine dust to be adsorbed to the insect screen 100 is delayed due to continuous use, the adsorption efficiency may decrease and the flow of air through the insect screen 100 may be blocked. Accordingly, it is possible to remove the heavy metal component adsorbed to the conductive network 110 from the conductive network 110 by vibrating the conductive network 110 through the vibrator 140 .

Of course, when the vibration is transmitted by the vibrator 140 in order to more effectively remove the heavy metal from the conductive network 110 , the current formation by the current forming unit 130 may be blocked. That is, the absorption function by the all-type unit and the vibration by the vibrator 140 may be selectively controlled by the control unit 200 .

Meanwhile, a plurality of current forming units 130 may be provided, and a plurality of vibrators 140 may also be provided. Here, when the current forming unit 130 and the vibrator 140 are provided in plurality, it may be advantageous to form a current flow or to transmit vibrations to be positioned opposite to each other with the conductive network 110 interposed therebetween. That is, each of the plurality of current forming units 130 and the plurality of vibrators 140 may be located at the edge of the conductive network 110 and located opposite to each other.

3 is a view showing the insect screen 100 that is controlled interlocking with the sensor unit 300 according to an embodiment of the present invention.

Referring to FIG. 3 , the insect screen 100 capable of preventing and removing fine dust indoors may further include a sensor unit 300 . The sensor unit 300 detects the insect screen 100 and the surrounding environment and transmits it to the controller 200 so that the controller 200 causes the insect screen 100 to be controlled by the current forming unit 130 or the vibrator 140 . can For example, the sensor unit 300 includes a first sensor 310 , a second sensor 320 , and a third sensor 330 . As a specific example, the sensor unit 300 may include a first sensor 310 for detecting time, a second sensor 320 for detecting wind pressure, and a third sensor 330 for detecting opening and closing of the door.

The first sensor 310 may detect a predetermined time. For example, the vibrator 140 may be driven at a predetermined time interval. Since the driving of the vibrator 140 may be selectively driven with the current forming unit 130 as described above, the driving unit may be driven in a state in which no current flows in the conductive network 110 . That is, the control unit 200 may be connected to the first sensor 310 to detect a predetermined time that is a sensing target of the first sensor 310 and drive the driving unit at a predetermined time period.

In addition, the second sensor 320 is a sensor for detecting wind pressure, and the mesh-shaped conductive network 110 through which air passes has a large amount of adsorption of the aforementioned heavy metals contained in fine dust, and the wind pressure is increased. Therefore, the second sensor 320 senses the wind pressure applied to the conductive network 110 and transmits it to the control unit 200, and when the control unit 200 detects a predetermined wind pressure or more, the vibrator 140 is driven to drive the conductive network Foreign substances adsorbed to (110) can be removed. Here, the removal means separation from the conductive network 110 .

In addition, the third sensor 330 may be a sensor that detects the opening and closing of the door. The insect screen 100 may be installed together with a door disposed on the indoor side. The insect screen 100 installed adjacent to the door and installed on the outdoor side may not operate in a closed state but may be operated in an open state. That is, when opened, current can flow through the conductive network 110 by the current forming unit 130 , and when closed, the vibrator 140 is driven to remove heavy metals and foreign substances adsorbed on the conductive network 110 . . Furthermore, the driving of the vibrator 140 may be operated when the door is closed, and further, may be operated when it is determined that the adsorption amount is large. The amount of the adsorbent may be according to the sensing information of the first sensor 310 or according to the sensing information of the second sensor 320 .

Referring to FIG. 4 , as described above, a power collecting step of collecting power from the generator 10 ( S10 ), a current forming step of allowing a current to flow in the conductive network 110 by the current forming unit 130 ( S20 ) , dust adsorption step (S30) in which dust (adsorbent such as heavy metal) is adsorbed to the conductive network 110 through which current flows, vibrator drive in which the vibrator 140 is driven by the sensing information sensed by the sensor unit 300 Step S40 and the dust removal step S50 in which dust is removed by driving the vibrator 140 may be sequentially performed. Also, the above sequence may be repeatedly performed.

Referring to FIG. 5 , the vibrator 140 may be driven for a predetermined time. Assuming that the predetermined time is displayed on the horizontal axis, it may include a section in which the vibration frequency increases/decreases nonlinearly during the entire time. can be formed. That is, the increase in frequency may occur rapidly and may decrease relatively gently.
