Description

Filter module of installation type air inlet}

The present invention relates to a filter module equipped with an air supply port, and more particularly, to a filter module equipped with an air supply port, which can minimize the inflow of fine dust and ultrafine dust inside, and is easily replaced.

Fine dust and ultra-fine dust are very small enough to be invisible, so they stay in the air. These are air that can adversely affect health by entering the lungs through the respiratory tract or moving through the blood vessels and entering the body. The importance of Korea is emerging.

In general, a ventilation device equipped with a ventilation device for supply and exhaust ventilation is installed in an apartment house, such as an apartment, to provide a pleasant environment by filtering contaminated air indoors. Conventional ventilation devices are formed to inflow outside air from the outside, and are connected by a duct that communicates indoors and outdoors together with a ventilation device that is formed so that indoor air is discharged to the outside, and the outside air is circulated inside and then discharged to the outside. It is formed to be.

However, in the conventional ventilation system as described above, since air ventilation paths such as supply and exhaust ducts are mainly installed in the ceiling space, the actual floor height of the building (from the floor of the room) is increased due to the increase in installation space due to the installation of the air ventilation path. The height up to the bottom of the upper floor) increases and the floor area ratio of the building increases due to this, which causes a problem that enormous construction costs are required for builders.

To solve this, Korean Patent Laid-Open No. 10-0008733 uses a ventilation device to supply external air supply to the room or exhaust contaminated air from the room to the outside, but separate distributors and air supply pipes are provided inside the ventilation system. It is formed so that supply air is directly supplied to each room such as bedroom, living room, kitchen, toilet, etc., and the air circulated in the room is recovered by a duct through a ventilator. An integrated intake pipe having a pipe is provided so that contaminated air can be quickly exhausted to the outside, and a technology for smooth supply and exhaust of supply and exhaust air is disclosed.

However, the filter of the existing ventilation system has a limitation in removing fine dust or ultra-fine dust, and the product with some fine dust and ultra-fine dust-response filters has a small filtration area due to the narrow application space, so the flow rate of the ventilation system is reduced. It is large, and even if a high-efficiency filter capable of removing fine dust and ultra-fine dust is applied, there is a problem in that perfect filtering is not performed due to the existence of leakage due to structural limitations. In addition, as shown in FIG. 1, when replacing the filter of the total heat exchanger in the conventional ventilation system, there is a problem that it is difficult for non-experts to perform due to the accompanying ceiling work of the building.

In addition, in order to remove fine dust and ultrafine dust, when the air purifier is used with the window closed, the concentration of carbon dioxide in the room gradually increases. That is, if the air purifier is used with the window closed to block fine dust, the concentration of carbon dioxide in the room increases, and as a result, there is a problem that ventilation is required.

First, referring to FIG. 1, a conventional ventilation device 10 and a ventilation system will be described. As an example, the conventional ventilation device 10 is a heat exchanger for warming or cooling air entering from outside air by heat (hot or cold) exhausted from the room, and may be a total heat exchanger capable of heat exchange between both direct and latent heat. . In addition, a conventional ventilation system may be provided with an air supply filter (11). That is, after external air flows into the ventilation device 10, it passes through the air supply filter 11 and collects dust while flowing into the room. Accordingly, the air that has passed through the air supply filter 11 is introduced into the room through the air supply pipe 12, and the air in the room is allowed to flow out through the exhaust pipe 13 to the outside.

At this time, the conventional air supply filter 11 has a limitation in removing fine dust and ultrafine dust at the level of a pre-filter. In addition, the air supply filter 11 has a problem that the filtering area is narrow due to the narrow space, and the flow rate of the ventilation device decreases due to a high differential pressure. In addition, due to the airtightness limit of the air supply filter 11, there is a problem of dust collection efficiency due to leakage even when a high-efficiency filter is applied, and when replacing the air supply filter 11, it is necessary to remove the ceiling of the building. It is troublesome and it is not easy to replace filters by non-experts.

That is, after the air supplied from the supply pipe 12 reaches the air diffusion member 17, the air flows toward the filter unit 110. In other words, as the air supplied from the supply pipe 12 reaches the air diffusion member 17, the flow direction is switched to the direction toward the filter unit 110, so that the air passes through the filter unit 110. When passing, the pressure loss can be minimized.

Next, further comprising a gasket 120 provided on the upper or lower portion of the filter unit 110, the filter unit 110 is provided between the fixing member 15 and the air diffusion member 17, It prevents the air from leaking to the outside, and induces the air to pass through the filter unit 110 to improve the dust collection efficiency of the filter unit 110. That is, the gasket 120 prevents the air supplied from the supply pipe 12 from leaking, passes through the filter unit 110, and then flows into the room.

This embodiment is different from the first embodiment in that the filter unit 210 is integrally formed with the air supply body 14. For a configuration overlapping with the first embodiment in this embodiment, a description of one embodiment will be used.

Referring to FIG. 4, the filter unit 210 is integrally formed on the upper side of the air diffusion member 17. That is, the air supply body 14 is configured to include the filter unit 210, so that when the air supply body 14 is installed, air supplied through the air supply pipe 12 can be collected. . In addition, the gasket 221 may be provided only on the upper side of the filter unit 210 or may be omitted. That is, the filter unit 210 and the air diffusion member 17 are integrally formed, and the filter unit 210 and the fixing member 15 are integrally formed, so that the gasket 221 can be omitted. There is an advantage.

Hereinafter, a filter module equipped with an air supply port according to a third preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. This embodiment is different from the first embodiment in that the filter unit 310 is provided to be spaced apart from the air supply main body 14. For a configuration overlapping with the first embodiment in this embodiment, a description of one embodiment will be used.

5, a circular shape having a hollow, having a larger diameter than the fixing member 15 and the air diffusion member 17, and having a fixing part 340 fixed to the ceiling surface and a hollow It is formed as, is provided on the upper portion of the filter unit 310, further includes a coupling portion 330 coupled to the fixing portion 340. Like the fixing member 15, the fixing part 340 is fixed to the ceiling by means such as an adhesive or a screw. In addition, the fixing part 340 includes a spiral groove (not shown) formed along the inner circumferential surface of the fixing part 340 on the inner circumferential surface of the fixing part 340. In addition, the coupling portion 330 includes a spiral protrusion 331 formed along the side surface of the coupling portion 330 on the side surface of the coupling portion 330. Therefore, when the coupling portion 330 is coupled to the fixing portion 340, the spiral protrusion 331 is inserted and fixed while being rotated into the spiral groove.

As a result, the filter unit 310 is provided to be spaced apart from the air diffusion member 17 at a predetermined interval, thereby forming a wider space in which the air introduced through the supply pipe 12 can be diffused, There is an advantage of reducing pressure loss and improving dust collection efficiency by selectively forming a larger size of the filter unit 310 as needed. In addition, since the filter unit 310 is formed to be spaced apart from the air supply body 14, there is an advantage that the filter unit 310 can be installed regardless of the shape of the air supply body 14. That is, the size of the filter unit 310 can be selected without restriction of the shape of the air supply main body 14, and accordingly, the size of the filter unit 310 is selectively selected and installed as necessary, Since the dust collection area can be maximized, the efficiency of the filter unit 310 can be increased.

Hereinafter, a filter module equipped with an air supply port according to a fourth embodiment of the present invention will be described in detail with reference to the accompanying drawings. This embodiment differs from the third embodiment in that it includes a coupling blade 431, a receiving portion 441, and a fixing tip 442. For a configuration overlapping with the third embodiment in this embodiment, a description of one embodiment will be used.

6 and 7, the coupling portion 430 includes a plurality of coupling blades 431 formed convexly on the outer circumferential surface of the coupling portion 430 and inserted into the fixing portion 440. In addition, the fixing part 440 has a plurality of receiving parts 441 to allow the coupling blade 431 to be inserted into the inner circumferential surface of the fixing part 440, and is formed convexly of an elastic material to the coupling blade ( It includes the fixing tip 442 for preventing the 431 from being separated from the receiving portion 441. In addition, the fixing part 440 includes a plurality of support parts 444 respectively supporting the plurality of coupling blades 431, and the support part 444 is formed in a shape corresponding to the coupling blade 431 It includes an insertion hole 443 through which the coupling blades 431 can be inserted. In this case, the support part 444 is provided under the coupling blade 431 and serves to support the coupling blade 431. Therefore, after the coupling blade 431 is inserted into the receiving part 441, it is rotated in one direction and formed to be mounted by being caught by the fixing tip 442 to facilitate the installation of the filter part 410. . That is, the coupling part 430 is formed detachably to the fixing part 440, so that the filter part 410 can be easily replaced, so that the size of the filter part 410 can be selectively adjusted. In other words, after the coupling blade 431 is inserted into the insertion hole 443, the coupling part 430 is rotated in one direction with respect to the fixing part 440, and is seated on the upper surface of the support part 444, and the The coupling part 430 is mounted on the fixing part 440 in a manner that is fixed by hanging on the fixing tip 442 and can be separated in the opposite order, so that the installation and replacement of the filter part can be easily performed. There is this.

In more detail, referring to (b) of FIG. 7, the fixing tip 442 is formed on the inner circumferential surface of the receiving part 441, and is formed at a point spaced apart from the center of the inner circumferential surface of the receiving part 441 . Therefore, after the coupling blade 431 is inserted into the receiving part 441, the coupling blade 431 is rotated in the direction in which the fixing tip 442 is formed, so that the coupling blade 431 becomes the fixing tip ( 442). That is, the fixing tip 442 is formed to be biased to one side of the receiving portion 441, and is formed at a position in which the coupling blade 431 can be inserted. At this time, the fixing tip 442 is formed of an elastic material to protrude from the inner circumferential surface of the receiving portion 441 in a horizontal direction toward the coupling blade 431, and the coupling blade 431 is formed of the coupling portion 430 ) Is formed to protrude in the horizontal direction toward the fixing tip 442 from the outer circumferential surface. Therefore, when the coupling portion 430 is attached to the fixing portion 440, even if vibration in the horizontal direction occurs due to interference between the coupling blade 431 and the fixing tip 442, the coupling portion 430 Is prevented from being separated from the fixing part 440 or a gap between the coupling part 430 and the fixing part 440, thereby allowing the air to pass through the gap between the coupling part 430 and the fixing part 440 There is an advantage in that it can be prevented from leaking out. In addition, the coupling blade 431, the receiving portion 441 and the fixing tip 442 are formed to be round so that they can be easily coupled. That is, the outer circumferential surfaces of the coupling wing 431, the receiving portion 441 and the fixing tip 442 are formed to be rounded, respectively, so that when the coupling portion 430 is attached to and detached from the fixing portion 440, the coupling There is an advantage that the wing 431, the receiving portion 441 and the fixing tip 442 are prevented from being damaged, and can be easily attached and detached.

In addition, due to the increase in the flow rate as described above compared to the conventional air supply body 14, the air supply pipe mounted filter module according to the fourth embodiment of the present invention has the air supply pipe ( As the flow rate through which the air supplied from 12) can be circulated is increased, there is an advantage in that the purification efficiency of the air is improved. In addition, the air supply port mounted filter module according to the fourth exemplary embodiment of the present invention allows the air supplied from the supply pipe 12 to be circulated inside the filter unit 410 compared to the conventional air supply main body 14. By increasing the available space, there is an advantage in that the purification efficiency of the air is improved.

Next, an experimental method for proving the effect of the present invention and the experimental results will be described. 8 is a diagram showing the measurement results of the pressure and flow rate of a filter module equipped with an air supply port according to a fourth embodiment of the present invention compared with a conventional product. The pressure loss was evaluated by the wind tunnel equipment and measurement method specified in KS B 6141 (Air Filter Unit for Ventilation). In addition, the flow rate was measured in the internal pipeline of the product with an anemometer specified in KS P 8202 (general anemometer). It can be seen that the pressure loss of the air-supply port-mounted filter module of the present invention is 20 Pa, which is 5 times lower than that of the conventional air supply flat filter and 3 times less than the existing total heat exchanger filter, and thus has a lower pressure loss than the conventional filter. In addition, it can be seen that the flow rate of the air-supply port-mounted filter module of the present invention is approximately 3.5 times higher than that of the conventional air-supply port plane filter, and approximately 1.8 times higher than that of the existing total heat exchanger filter. As a result, the air-supply port-mounted filter module of the present invention has an advantage in that the dust collection efficiency is higher than that of conventional devices.

Next, FIG. 9 shows the measurement results of the indoor fine dust reduction rate of the filter module equipped with an air supply port according to a fourth embodiment of the present invention, compared with existing products. The indoor fine dust reduction rate is a predicted result based on the actual data (flow rate, dust collection efficiency) for each case using the material exchange method (Seidel method). It can be seen that the air-supply port-mounted filter module of the present invention exhibits a lower value than the average daily standard value of ultrafine dust in less time than the conventional air-supply air filter and the total heat exchanger filter. The filter module equipped with an air supply port of the present invention has an advantage in that the dust collection efficiency is higher than that of the conventional device.

In addition, the filter module equipped with an air supply port of the present invention has the advantage of removing not only fine dust and ultrafine dust, but also carbon dioxide, odors, VOCs (volatile organic compounds), formaldehyde, and radon.
