The second space S2 and the fourth space S4 may communicate with each other through a peak and a valley formed in the other heat exchange plate 142b of the two heat exchange plates 142a and 142b, and the first The indoor air moving from the space S1 to the third space S3 through the heat exchanger 140 moves from the second space S2 to the fourth space S4 through the heat exchanger 140. Air and the inside of the heat exchanger 140 do not mix with each other and may move in a cross direction.

Meanwhile, the heat exchanger 140 may be supported through the plurality of partition walls 117 and may be detachably coupled to the intermediate case 123 .

That is, one end of each of the plurality of partition walls 123b may support an edge of the heat exchanger 140 .

To this end, each of the plurality of partition walls 123b may include a support groove 123c that is drawn inwardly to support the edge of the heat exchanger 140 at one end thereof.

For example, as shown in the enlarged view of FIG. 5 , the support groove 123c may be formed to include a 'v'-shaped cross section so as to surround the corners of the heat exchanger 140 , respectively.

Accordingly, when the edge of the heat exchanger 140 is simply inserted into the plurality of support grooves 123c, the heat exchanger 140 can be supported through the plurality of support grooves 123c, and the inside The space S may be divided into first to fourth spaces S1 , S2 , S3 , and S4 through the plurality of partition walls 123b and the heat exchanger 140 .

In this case, as shown in FIGS. 5 and 6 , the first inner case 121 side includes a through portion 121a that is formed through a predetermined area in an area corresponding to one surface of the heat exchanger 140 . As shown in FIGS. 3 and 13 , the through portion 121a may be sealed through a cover plate 164 detachably coupled to the first inner case 121 .

The filter member 150 may filter the outdoor air introduced into the inner space S through the outdoor air inlet I1 from the outside.

The filter member 150 is disposed between the rear cases 112 and 212 and the main body 120 so that the outdoor air flowing into the inner space S is filtered and then introduced into the heat exchanger 140 side. can be

That is, the filter member 150 may be disposed outside the first inner case 121 to cover the outdoor air inlet I1 .

Accordingly, the outdoor air supplied from the outdoors to the indoor through the operation of the first blower 131 is removed from foreign substances such as yellow dust or fine dust in the process of passing through the filter member 150, and then the main body 120. The quality of indoor air can be improved by moving to the indoor space through the outdoor air outlet (O1).

For example, the filter member 150 may be a well-known HEPA filter (High Efficiency Particulate Air Filter). However, the type of the filter member 150 is not limited thereto, and all known various types of filters may be used as long as foreign substances contained in the air can be removed. For example, a filter including at least one layer of electrospun nanofibers capable of filtering fine dust less than PM 2.5 may be used.

Details of the filter member 150 will be described later.

In this case, the filter member 150 may be coupled to one side of the body 120 via a filter cover 161 that is detachably coupled to the body 120 .

For example, the filter cover 161 may be detachably coupled to one side of the first inner case 121 .

That is, as shown in FIG. 19 , the filter cover 161 may be a plate-shaped member having a plurality of through holes to allow air to pass therethrough, and the first inner case 121 to cover the filter member 150 . ) may be detachably coupled to one side of the.

Accordingly, the filter member 150 can be prevented from being separated from the main body 120 through the filter cover 161, and when replacement of the filter member 150 is required, the filter member 150 is separated from the rear surface of the main body 120. After the filter cover 161 is separated from the main body 120 in a state in which the cases 112 and 212 are removed, the filter member 150 can be easily replaced.

Meanwhile, as described above, the rear cases 112 and 212 may serve as passages through which outdoor air moves from the outside toward the main body 120 or through which indoor air moves from the indoor space to the outside.

That is, the rear cases 112 and 212 allow outdoor air to move from the outside toward the outdoor air inlet I1 formed in the main body 120 or indoor air discharged from the indoor air outlet O2 formed in the main body 120 . It can allow air to move to the outside.

At this time, the ventilation air purifiers 100 and 200 according to an embodiment of the present invention may be implemented in a form installed on the window side depending on the shape of the rear case 112 and 212, or installed on a wall defining an indoor space. may be implemented as

That is, the ventilation air purifiers 100 and 200 according to an embodiment of the present invention are installed on the window side as shown in FIGS. 1 to 10 according to the shape of the rear cases 112 and 212 coupled to the main body 120 . It may be implemented as a window-type ventilation air purifier 100, or may be implemented as a perforated ventilation-type air cleaner 200 installed on a wall as shown in FIGS. 11 to 18 .

In this case, the window-type ventilation air purifier 100 and the perforated-type ventilation air purifier 200 have the same contents as those described above except for the rear cases 112 and 212, so a detailed description will be omitted, and FIG. The detailed configuration of the main body 120 shown in FIGS. 5 to 8 may be equally applied to the ventilation air purifier 200 of the perforated type as well as the ventilation air purifier 100 of the window type.

For example, the rear cases 112 and 212 may be coupled to one surface of the main body 120 , and may include at least one opening 113 penetrating through a predetermined area to allow outdoor air to pass therethrough.

That is, as shown in FIGS. 2 to 4 , 9 and 10 , the rear cases 112 and 212 may be detachably coupled to the first inner case 121 side of the main body 120 , and the filter At least one opening 113 may be formed through a position corresponding to the cover 161 .

In addition, the rear cases 112 and 212 may have at least one through hole 114 penetrating at a position corresponding to the outdoor air outlet O1 of the main body 120 .

Accordingly, the outdoor air passes through the rear cases 112 and 212 through the at least one opening 113 from the outside and the filter member 150 is fixed to one side of the main body 120 through the filter cover 161. After passing through, it can move to the second space S2 through the outdoor air inlet I1 formed in the main body 120 .

In addition, the indoor air introduced into the first space S1 from the inside through the indoor air inlet I2 may be discharged to the rear side of the main body 120 through the indoor air outlet O2, and the main body ( The indoor air discharged to the rear side of the 120 may be discharged to the outside through the through hole 114 .

As another example, the rear cases 112 and 212 may be coupled to one surface of the main body 120 as shown in FIGS. 11 to 14 , and a hollow protrusion extending from one surface of the rear cases 112 and 212 ( 215), and the protrusion 215 may be installed to pass through a wall defining an indoor space.

Here, the protrusion 215 may be integrally formed with the rear cases 112 and 212 or may be detachably coupled to the rear cases 112 and 212 .

In this case, the protrusion 215 has a first partition space 215a and a second partition space ( 215b).

Here, the first compartment 215a may communicate with the outdoor air inlet I1 and the second compartment 215b may communicate with the indoor air outlet O2.

That is, the ventilation type air purifier 200 of the perforated type may further include a vent cover 216 coupled to the rear cases 112 and 212 so as to be positioned between the main body 120 and the rear cases 112 and 212. , the vent cover 216 may connect the second partition space 215b and the indoor air outlet O2 to each other.

Specifically, as shown in FIGS. 15 and 16 , the vent cover 216 includes a plate-shaped support plate 216a having a predetermined area and a raised portion 216b protruding from one surface of the support plate 216a and the It may include a hollow coupler 216c connected to the end of the support plate 216a, and the hollow part of the coupler 216c may communicate with a space defined through the raised part 216b.

Such a vent cover 216 may be coupled to the protrusion 215 side so that a portion of the support plate 216a covers an area corresponding to the second partition space 215b of the protrusion 215, and the coupling The sphere 216c may be connected to the indoor air outlet O2 of the main body 120 .

Accordingly, the vent cover ( 216), the indoor air moving to the second compartment 215b may move smoothly along a predetermined path without mixing with each other.

Accordingly, the outdoor air passes through the rear cases 112 and 212 through the first compartment 215a from the outside, and then the filter member fixed to one side of the main body 120 fixed through the filter cover 161 ( After passing through 150), it may move to the second space S2 through the outdoor air inlet I1 formed in the main body 120 .

In addition, the indoor air introduced into the first space S1 from the inside through the indoor air inlet I2 may be discharged to the rear side of the main body 120 through the indoor air outlet O2, and the main body ( The indoor air discharged to the rear of the 120) may be discharged to the outside after moving to the second partition space 215b along the vent cover 216.

As described above, the ventilation air purifier 200 according to an embodiment of the present invention can be smoothly moved along a predetermined path without mixing indoor air and outdoor air through one protrusion 215 fixed to the wall.

Meanwhile, the ventilation air purifiers 100 and 200 according to an embodiment of the present invention may include a control unit 170 for overall driving. That is, the control unit 170 may control the driving of the first blower 131 and the second blower 132 , and a chipset such as an MCU may be mounted on a circuit board.

Such a control unit 170 may be disposed to be located on one side of the main body 120 as shown in FIGS. 2 and 13 . For example, the control unit 170 may be disposed to be positioned on one surface of the second inner case 122 .

However, the installation position of the control unit 170 is not limited thereto, and may be provided at an appropriate position according to design conditions.

On the other hand, in the ventilation air purifiers 100 and 200 according to an embodiment of the present invention, a separate heater (not shown) is installed on the movement path of the indoor air or the movement path of the outdoor air, so that the indoor air or Indoor air can also be heated. In this case, the heater may be operated under the control of the controller 170 in a state in which any one of the first blower 131 and the second blower 132 is stopped.

Through this, it is possible to prevent dew condensation from occurring on the movement path through which the indoor air moves or the movement path through which the outdoor air moves.

In addition, the ventilation air purifier 100 according to an embodiment of the present invention may be additionally provided with an ultraviolet generating means 190 capable of irradiating ultraviolet rays to the outside air flowing into the main body 120 from the outside. . For example, the ultraviolet generating means 190 may be a known UV lamp.

As shown in FIG. 8 , the ultraviolet generating means 190 may irradiate ultraviolet rays toward the outside air in a state before being introduced into the inside of the heat exchanger 140 .

That is, the ultraviolet generating means 190 may be disposed to be located on the side of the second space S2 , and may be driven through the control unit 170 .

Through this, the outside air flowing into the second space S2 from the outside through the outdoor air inlet I1 is sterilized through the UV rays irradiated from the UV generating means 190 and then moves to the heat exchanger 140 side. can

Accordingly, the external air introduced into the heat exchanger 140 does not contain microorganisms such as bacteria, thereby preventing bacterial propagation inside the heat exchanger 140 .

Meanwhile, the ventilation air purifiers 100 and 200 according to an embodiment of the present invention may further include a filter member (not shown) for filtering indoor air discharged from the room to the outside.

Such a filter member may be disposed at a position corresponding to the indoor air outlet O2, and the filter member may be a known pre-filter for removing foreign substances contained in the air.

However, the type of the filter member disposed at the indoor air outlet O2 is not limited thereto, and may be the same type of filter member as the aforementioned filter member 150 or may be provided as a HEPA filter.

In addition, the filter member disposed at a position corresponding to the indoor air outlet O2 may be provided as a separate member, but the above-described filter member 150 is provided with the indoor air outlet O2 and the outdoor air inlet I1. By being provided to have an area that can cover all of the , both the external air supplied to the indoor space and the indoor air discharged to the outdoors through one filter member 150 may be filtered.

Meanwhile, the ventilation air cleaners 100 and 200 according to an embodiment of the present invention may be driven so that the first blower 131 and the second blower 132 have different operating times.

That is, the control unit 170 determines that the operating time of any one of the first blower 131 and the second blower 132 for flowing the relatively high temperature air is the operating time of the other of the first blower 131 and the second blower 132 for flowing the relatively low temperature air. It can be controlled to run for a longer time.

Through this, in the ventilation air purifiers 100 and 200 according to an embodiment of the present invention, even if dew condensation occurs inside the heat exchanger 140 during the heat exchange between indoor air and outdoor air through the heat exchanger 140 , Condensation can be prevented by allowing relatively high-temperature air to pass through the heat exchanger 140 for a predetermined period of time.

For this reason, it is possible to prevent in advance the propagation of bacteria such as mold inside the heat exchanger 140 .

As a non-limiting example, as shown in FIG. 26 , when the ventilation air purifiers 100 and 200 according to an embodiment of the present invention are driven through a user's operation, the control unit 170 is configured as a first step (St1). For ventilation, both the first blower 131 and the second blower 132 may be operated.

Accordingly, the outside air may be sucked in from the outside through the driving of the first blower 131 and then discharged to the indoor space through the heat exchanger 140 , and the indoor air is driven by the second blower 132 . After being sucked from the indoor space through the heat exchanger 140, it may be discharged to the outside.

Then, when a signal for turning off or temporarily stopping the driving of the ventilation air purifier 100 and 200 is input to the control unit 170 through the user's manipulation, the control unit 170 controls the outdoor air temperature as a second step (St2). (To) and the temperature (Ti) of the indoor air can be compared.

Through this, the control unit 170 may selectively drive any one of the first blower 131 and the second blower 132 as the third step (St3) and change the other to an OFF state.

That is, if the temperature of the outdoor air temperature To is relatively higher than the indoor air temperature Ti through the second step (St2), the control unit 170 determines the ON state of the first blower 131 . While maintaining, the second blower 132 may be changed to an off state.

On the other hand, if the temperature of the outdoor air temperature To is relatively lower than the indoor air temperature Ti through the second step St2, the control unit 170 turns the first blower 131 into an off state. While changing, the on state of the second blower 132 may be maintained.

Through this, the relatively high temperature air among the indoor air and the outdoor air may be additionally introduced into the heat exchanger 140 for a predetermined period of time. For this reason, the inside of the heat exchanger 140 may be dried using the heat of relatively high temperature air, thereby preventing condensation from occurring inside the heat exchanger 140 .

Then, as a fourth step (St4), the control unit 170 may stop the operation of the blower that is in an on state selectively among the first blower 131 and the second blower 132 . That is, when the first blower 131 is in the on state and the second blower 132 is in the off state, the first blower 131 can be changed to the off state while maintaining the off state of the second blower 132, , when the first blower 131 is in the off state and the second blower 132 is in the on state, the second blower 132 may be changed to the off state while maintaining the off state of the first blower 131 . Through this, the ventilation air purifiers 100 and 200 according to an embodiment of the present invention may be changed to an off state or a pause state.

On the other hand, if the filter member 150 applied to the ventilation air cleaner 100 and 200 according to an embodiment of the present invention can remove fine dust contained in the air, all known various filter members can be applied, but replace It can be configured to increase the cycle, increase the removal efficiency, and lower the pressure loss.

In addition, the filter member 150 may disable or remove an antivirus such as Corona 19 from outdoor air flowing into the room by adding an antiviral function.

In addition, an antibacterial function may be added to the filter member 150 .

Accordingly, when the ventilation air purifier 100 or 200 according to an embodiment of the present invention is operated, as described above, outdoor air in a state in which pollutants such as yellow dust or fine dust has been filtered while the indoor air is discharged is introduced into the room. Ventilation can reduce the concentration of carbon dioxide in the indoor air, while also allowing the discharge of pollutants present in the room, thereby maintaining a comfortable indoor air.

In addition, as outdoor air in a state in which an antivirus such as Corona 19 is disabled or removed through the filter member 150 is introduced into the indoor space, it is possible to prevent disease outbreaks and disease transmission due to viruses in advance.

On the other hand, the filter member 150 for filtering the outdoor air is configured to suppress the growth of bacteria, mold, viruses, etc., it is possible to prevent contamination of the heat exchanger and bacteria and viruses from entering the room.

To this end, the filter member 150 may include a porous first member 151, a porous second member 152 and a third member 153 electrostatically treated as shown in FIGS. 21 to 23 . can

The first member 151 is a porous member that has been electrostatically treated, and as a filter medium through which outdoor air primarily passes, it can filter fine dust, dust, etc. contained in the air by using electrostatic force. For example, the first member 151 may be a known nonwoven fabric, preferably a melt blown nonwoven fabric.

Here, the electrostatic treatment may be performed on the entire area of the first member 151 , but may be processed only on a partial area of the total area of the first member 151 , and in manufacturing a typical electrostatic treatment filter A well-known method used can be employ|adopted suitably.

In addition, in the first member 151, the diameter and basis weight of the fiber can be adjusted according to the purpose, and in order to guarantee improved filtration performance and durability, the first member 151 is a fiber having a diameter of 1 to 10 μm. may include, and the basis weight of the first member 151 may be 15 to 50 g/m 2 , and in another example, the basis weight may be 20 to 35 g/m 2 . In addition, the average pore diameter of the first member 151 may be 20 μm or less, and in another example, 10 μm.

If the average pore diameter of the first member 151 is excessively small, air permeability may decrease and pressure loss may increase. Conversely, when the average pore diameter of the first member 151 is excessively large, filtration efficiency may be reduced.

In addition, when the average diameter of the fibers forming the first member 151 is excessively small, air permeability may decrease and pressure loss may increase. Conversely, when the average fiber diameter of the first member 151 is excessively large, filtration efficiency may be reduced.

In addition, if the basis weight of the first member 151 is excessively low, the filtration efficiency may be lowered as the deviation increases, or a uniform filtration efficiency may not be expressed. Conversely, if the basis weight of the first member 151 is excessively large, air permeability may be reduced and pressure loss may increase.

Meanwhile, the fibers forming the first member 151 may include a synthetic polymer component selected from the group consisting of polyester, polyurethane, polyolefin and polyamide, or a natural polymer component including cellulose.

The second member 152 may secondarily filter the air that has passed through the first member 151 .

To this end, the second member 152 may be a nanofiber web in which nanofibers are accumulated, and the nanofiber web may be in which nanofibers are accumulated in a three-dimensional network structure.

For example, the second member 152 may include a known fiber-forming component capable of forming nanofibers, and preferably, the fiber-forming component may be a component capable of electrospinning.

The pore diameter of the second member 152 may have a size capable of physically filtering fine dust of PM2.5 or less, and the second member 152 may be configured to prevent a decrease in the flow rate of passing air. Euros may be included.

As the second member 152 is provided together with the above-described first member 151, it compensates for the problem of a reduction in collection efficiency due to static electricity that may occur in the electrostatically treated first member 151, and has a filtration efficiency designed for a long time. can be maintained.

That is, the electrostatically treated first member 151 uses electrostatic force to adsorb dust to the fiber surface, and as time passes, the electrostatic force decreases. Accordingly, when the filter member 150 is configured using only the electrostatically treated first member 151 , the filtration efficiency of the filter member 150 decreases as time passes, so there is a problem that the replacement cycle is very short.

However, when the filter member 150 is composed of the first member 151 and the second member 152 subjected to electrostatic treatment, the reduction in collection efficiency is small compared to the filter member composed only of the first member 151, Even after several months, the collection efficiency can be maintained at more than 95% of the initially designed value.

Meanwhile, the second member 152 may have an antiviral function by further including an antiviral component in the nanofiber.

For example, the second member 152 may be provided with an antiviral coating layer on the nanofiber web, and the antiviral coating layer may include an antiviral component.

Here, the antiviral component may include an antiviral fusion protein, and the antiviral fusion protein may be formed by binding an antiviral motif to an adhesive protein. The antiviral motif may be a motif that functions to block infection by inhibiting the proliferation of the virus, annihilating the virus itself, or participating in the mechanism of the host being infected by the virus.

24 and 25 , the antiviral motif may have a function of directly or indirectly destroying an outer membrane, which is a protective layer of a virus. In addition, when the virus infects a host cell, the antiviral motif directly or indirectly destroys a protein that binds to a receptor of a host cell (ex. the spike protein of coronavirus), or directly or indirectly disables the protein. can have

Here, the direct or indirect meaning may mean that the antiviral motif directly performs the corresponding function or is ultimately involved in the beginning or intermediate process in performing the corresponding function.

The antiviral motif may be used without limitation as long as it is a known motif known to have antiviral effects such as extinction and inactivation of the aforementioned virus.

As a non-limiting example, the antiviral motif is any one peptide selected from the group consisting of the amino acid sequence of SEQ ID NO: 1 to SEQ ID NO: 7, a peptide to which one or more amino acid sequences selected from the group are linked, or one selected from the group It may be a peptide comprising more than one amino acid sequence as a basic sequence.

Here, the motifs according to SEQ ID NOs: 1 and 2 may be useful for SARS coronavirus, the motifs according to SEQ ID NOs: 3 to 7 may be useful for influenza A virus, and the motif according to SEQ ID NO: 7 may also be useful for HSV have.

In addition, the antiviral motif may be, for example, a peptide having 3 to 100 amino acids, more preferably 3 to 20 amino acids.

In addition, the virus targeted by the antiviral motif is not limited in the case of a known virus, and non-limiting examples thereof include JV, HSV, HIV, IPNV, VHSV, SHRV, HCMV, IAV, Japanese encephalitis virus, Ebola virus, It may be rhinovirus, adenovirus, measles virus, hepatitis B virus, influenza A and the like.

The above-described antiviral motif may be provided in the nanofiber web by itself without forming a fusion protein, but it may be difficult to fix only the antiviral motif in the nanofiber web for a long time. In order to solve this problem, in the present invention, the antiviral motif can be implemented in the form of a fusion protein combined with a junction protein, and it can be provided on the fiber web or the surface of the fiber forming the fibrous web.

The adhesive protein may function as an adhesive component that provides adhesion between the antiviral motif and the fibrous web or the fiber surface forming the fibrous web. In addition, the binding between the antiviral motif and the adhesive protein may be a covalent bond, and more specifically, the carboxy terminus, amino terminus, or both carboxy terminus and amino terminus of the adhesive protein may be bound by a peptide bond.

On the other hand, the antiviral motif and the adhesion protein can be combined through a known method, for example, can be prepared through a recombinant protein production method using E. coli. Meanwhile, the adhesive protein and the antiviral motif may be directly covalently bonded, but the present invention is not limited thereto and may be indirectly coupled between the adhesive protein and the antiviral motif by adding a third material as a spacer.

In addition, the adhesive protein may be used without limitation in the case of a protein having a known adhesion function, but may be, for example, a mussel-derived adhesion protein, and a known adhesion protein commonly referred to as a mussel-derived adhesion protein may be used without limitation. have. Preferably, the adhesive protein may be any one protein selected from the group consisting of the amino acid sequence of SEQ ID NO: 8 to SEQ ID NO: 21, or a protein to which one or more amino acid sequences selected from the group are linked.

In addition, the adhesive protein is a coating layer in the form of aggregates formed by reacting with an aggregation inducing component including a carbodiimide coupling agent and a hydroxy succinimide-based reactant, which may be further contained in the coating composition to be described later. Through this, the antiviral motif can be fixed on the fiber web or the fiber surface forming the fiber web with improved adhesive strength. In addition, by preventing or minimizing the disabling of the antiviral motif for a long time at room temperature, such as decomposition, denaturation, etc., the antiviral performance can be maintained for a long time, and storage stability and friction fastness can be improved.

On the other hand, the adhesive protein may contain a guiding moiety in order to express more improved fibrous web or adhesion properties with the fiber surface forming the fibrous web. Mussel adhesive proteins are known to have adhesive properties, but as a result of the study by the present inventors, when these adhesive proteins are used as they are, they show no or insignificant level of adhesive (or adhesion) properties, so it may be difficult to fix the antiviral motif on the surface of the substrate. .

In order to improve this, it can be modified to contain a guide moiety in the adhesion protein, and in this case, improved adhesion performance can be expressed. The modification may be performed by appropriately using a known method by modifying some or all of the tyrosine residues contained in the adhesion protein with a guide residue. For example, the modification may be performed using an enzyme, and the enzyme may be, for example, tyrosinase.

As for the method of modifying the tyrosine residue into the dopa residue using tyrosinase, the antiviral fusion protein having an adhesive protein was prepared with 25-100 mM ascorbic acid, 20-100 mM sodium acetate, 20-100 mM sodium borate. After dissolving in a buffer solution to a concentration of 0.01 ~ 10 mg/ml, oxygen is injected for 10 ~ 1 hour to saturate the oxygen in the solution, and then tyrosinase is added to a final concentration of 10 ~ 50 μg/ml. After mixing and stirring under oxygen conditions for 30 minutes to 2 hours, the reaction is terminated by adding acetic acid to a final concentration of 2 to 10%, desalting and concentration of the finished reaction solution with 1 to 10% acetic acid solution, followed by freeze-drying Through this process, a dopa-modified antiviral fusion protein in powder form can be obtained.

The antiviral fusion protein containing the waveguide moiety prepared by the above-described method can be easily fixed on the fiber web or the fiber surface forming the fiber web without other adhesive components. Inadvertent chemical reaction between the ingredient and the antiviral motif, or deterioration or inability of activity due to physical blocking can be prevented.

In addition, the antiviral component may further include a heterogeneous substance having an antiviral function in addition to the above-described antiviral fusion protein. The heterogeneous material may be a known organic material or inorganic material. For example, the heterogeneous material may be an inorganic material in which a substituent having proton donating or proton water solubility is disposed on a surface contacted by a virus, and specific examples include a phosphate compound of a titanium group element such as zirconium phosphate, hafnium phosphate, titanium phosphate, aluminum phosphate , inorganic phosphoric acid compounds such as hydroxyapatite (phosphate mineral); inorganic silicic acid compounds such as magnesium silicate, silica gel, aluminosilicate, sepiolite (hydrous magnesium silicate), montmorillonite (silicate mineral), and zeolite (aluminosilicate); It may be alumina, titania, hydrous titanium oxide, or the like. Alternatively, the heterogeneous material may be a salt containing a metal such as silver or an ion thereof.

The above-described antiviral component may be implemented with an antiviral coating layer by processing the antiviral coating composition on the fiber web or fibers forming the fibrous web. At this time, the fibrous web implemented using the fiber having the antiviral coating layer treated with the antiviral coating composition on the fiber may be implemented by a conventional nonwoven fabric manufacturing process.

The antiviral coating composition may further include a solvent or stabilizing buffer solution for dissolving the antiviral component in addition to the antiviral component including the above-described antiviral fusion protein. The solvent may be water and/or an organic solvent, and 20 to 100 mM Tris or sodium hydrogen carbonate buffer solution having a pH of 8 to 8.5 may be used.

In addition, the above-described antiviral fusion protein may be contained in the coating composition at a concentration of 0.001 to 1 mg/ml, as another example, 0.001 to 0.1 mg/ml, and if contained at a high concentration, antiviral properties may be improved, but , it may block the pores of the fibrous web to which the coating composition is applied, which may be undesirable if the pores of the fibrous web are to be maintained.

On the other hand, the antiviral coating composition comprising the antiviral fusion protein containing the above-described guidepa moiety can improve the adhesion of the implemented antiviral coating layer, but additional cost, time and effort are required according to the modification. The antiviral coating composition according to another embodiment may further include an aggregation-inducing component including a carbodiimide coupling agent and a hydroxy succinimide-based reactive agent in the coating composition without modifying the adhesive protein.

The aggregation-inducing component is a material for introducing the antiviral fusion protein to the surface of the substrate, and in case the antiviral fusion protein is treated alone or on the surface of the fiber constituting the fibrous web using a conventional method, the antiviral fusion protein It is possible to improve the adhesion between the coating layer and the surface of the.

Specifically, the aggregation-inducing component aggregates the antiviral fusion protein into granules, and the antiviral coating layer can be implemented in such a way that these granules are adsorbed to the surface of the substrate to form an aggregate. The coating composition using the aggregation-inducing component can enhance the adhesion of the antiviral fusion protein, and it can stably maintain its shape and activity even under changes in external temperature or humidity, so it has excellent storage stability and friction fastness, and antiviral The effect can last for a long time.

On the other hand, the antiviral coating layer implemented through the antiviral coating composition containing the aggregation inducing component may include a carbodiimide-based compound. It may remain in the antiviral coating layer through bonding to a hydroxyl group, a sulfone group, or the like.

On the other hand, the granular form in which the antiviral fusion protein is aggregated due to the aggregation inducing component is difficult to see as due to a specific chemical bond between the fusion proteins, for example, an amino bond between a carboxyl group and an amine group by a conventionally known carbodiimide coupling agent. , This is because the adhesive protein, for example, a plurality of hydroxyl groups and sulfone groups included in the mussel-derived adhesive protein, can also react with the carbodiimide coupling agent. Therefore, the granular form formed by the antiviral fusion protein according to the present invention having a plurality of reaction sites is difficult to be regarded as due to a specific reaction and a chemical bond resulting therefrom. can be seen as a result of

The carbodiimide coupling agent may be used without limitation in the case of a coupling agent that allows the antiviral fusion proteins to bind to each other, for example, 1-[3-(dimethylamino)propyl]-3-ethylcarboimide hydrochloride (EDC) or N,N'-dicyclohexylcarboimide (DCC).

In addition, the reactive agent is provided to prevent the antiviral fusion protein in a coupled state with carbodiimide from being hydrated, thereby increasing the efficiency of antiviral fusion proteins aggregating with each other. For example, N-hydroxysuccin is It may be one of imide (NHS) and N-hydroxysulfosuccinimide (Sulfo-NHS), or a mixture thereof.

The aggregation inducing component may include the carbodiimide coupling agent and the reactant in a weight ratio of 1:0.5 to 20. If they are not included in an appropriate ratio, it is difficult to achieve the desired effect of the present invention, and there is a fear that the durability of the implemented antiviral coating layer and the activity of the antiviral motif may be reduced.

In addition, the aggregation-inducing component may further include sodium acetate, phosphate buffer or MES buffer as an active ingredient to improve reactivity. In this case, the active ingredient may be included in an amount of 1 to 100 parts by weight based on 100 parts by weight of the carbodiimide coupling agent.

In addition, the above-mentioned aggregation component to the coating composition may be added in a liquid phase dissolved in a solvent, in which case water or an organic solvent may be used as a solvent, preferably water and/or ethanol may be used, and coating In terms of increasing the volatilization rate of the solvent in the composition, ethanol may be used as a solvent. When vaporization of the solvent is slow after treatment of the coating composition, it may be difficult to form an antiviral coating layer with a desired content and thickness, as the coating composition flows from the fiber web or the fiber surface forming the fiber web.

On the other hand, when the coating composition further contains an aggregation inducing component, a reaction between the antiviral fusion protein and the aggregation component may be induced until the coating composition is treated on the fiber web or the surface of the fiber forming the fiber web, and if the reaction is the target If the fiber web or the fiber surface forming the fiber web is treated after being excessively advanced beyond one level, it may be difficult to form an antiviral coating layer. Accordingly, it is preferable that the coating composition further include a delay component capable of delaying the reaction between the antiviral fusion protein and the aggregation inducing component, or the coating composition is stored under conditions capable of delaying the reaction, for example, a low temperature condition.

Alternatively, in order to further improve storage stability, the antiviral coating composition may be composed of a two-component coating composition comprising a first liquid containing an antiviral component and a second liquid containing the aggregation component. In this case, the first liquid may include water as a solvent, and the second liquid may include ethanol.

In addition, the antiviral coating composition may further include an oxidizing agent such as sodium periodate and hydrogen peroxide, and through this, it may be easier to achieve the object of the present invention.

As another example, the second member 152 may further contain an antiviral component in the nanofiber to perform an antiviral function. In this case, the antiviral component may include a surfactant, and specifically, a surfactant in which a functional group included in the surfactant binds to a virus to express antiviral performance may be used.

As a specific example, a polyoxyalkylene alcohol type nonionic surfactant may be used. Specific examples of the polyoxyalkylene alcohol type nonionic surfactant include polyoxypropylene glycol, polyoxyethylene glycol, polyoxyethylene polyoxypropylene glycol, polyoxyethylene alkyl ether, polyoxyethylene polyoxypropylene alkyl ether, acetylene glycol or acetylene alcohol. In addition, anionic surfactants such as C8 to C22 alkyl sulfonates and/or alpha sulfonated carboxylic acids or esters thereof, specifically linear alkyl benzene sulfonic acids, can also be used, in addition to cationic, Amphoteric surfactants may also be used.

The third member 153 may be a porous member performing a supporting function of the filter member.

The third member 153 may be disposed between the first member 151 and the second member 152 , but is not limited thereto, and may be disposed on one surface of the second member 152 .

In this case, the third member 153 is not particularly limited as long as it is a porous member that normally functions as a support.

As an example, the third member 153 may be a woven fabric, a knitted fabric, or a non-woven fabric, and as a non-limiting example, the third member 153 may be a thermal bonding non-woven fabric.

However, the material of the third member 153 is not limited thereto, and may include synthetic fibers selected from the group consisting of polyester, polypropylene, nylon and polyethylene.

Meanwhile, the filter member 150 may further have an antibacterial function. With this in mind, the filter member 150 may further include a fourth member 154 disposed between the first member 151 and the third member 153 as shown in FIG. 23 .

Here, the fourth member 154 may be formed including a known component having antibacterial properties, but preferably may be formed of a fiber containing silver that exhibits antibacterial properties.

The silver-containing fiber may be a silver wire made of silver alone, a metal wire containing other metals such as copper other than silver, or a ply-twisted yarn in which a silver wire and/or a metal wire containing silver and a conventional non-metal fiber are braided. have.

When describing a metal wire containing other metals, such as copper, it may be linearly formed by mixing a metal other than silver in a non-solid state with silver, that is, in a non-solid state, ie, silver and non-alloy state. When a metal other than silver is mixed with silver in a non-solid state, the silver and the other metal may be arranged such that silver and other metal occupy a predetermined area regularly or irregularly in a single linear region, For example, it may have a double structure in which a layer is formed by enclosing silver on the outside of the copper wire.

In this case, the copper wire may impart excellent flexibility to the silver wire, and the surrounding silver may have an average thickness of 3 to 3200 nm, and preferably, an average thickness of 5 to 3000 nm. If the average thickness of the surrounding silver is less than 3 nm, it is easy to manufacture so that copper, which is the central metal, is exposed to the outside, so that the antibacterial function may be reduced, and the silver may be detached from the silver wire, thereby further reducing the antibacterial function. In addition, when the average thickness of the surrounding silver exceeds 3200 nm, the flexibility of the silver wire may decrease.

Next, a description of the ply-twisted yarn in which a silver wire is braided with a non-metallic conventional fiber is described. A silver wire and a conventional fiber are a known manufacturing method in the field of textiles in which two types of fibers are plied, and a known arrangement structure of two types of fibers. It may be a ply-twist yarn implemented by appropriately employing it.

In this case, the silver wire used may be a wire made of only silver or a metal wire containing silver and other metals. For example, the ply-twisted yarn is a yarn having a triple structural cross section including a core yarn, a first covering yarn including a silver line surrounding the core, and a second covering yarn surrounding the outside of the first covering yarn surrounding the core yarn can

The core and second covering yarns may be used without limitation as long as they are fibers that can be used to improve the flexibility and elasticity of the ply-twisted yarn, and preferably, any one or more selected from natural fibers and synthetic fibers may be used, and more preferably, poly Ester-based fibers may be used.

In addition, the core yarn and the second covering yarn may be formed of a mono yarn or a plurality of filament yarns, and preferably a fiber formed of a plurality of filament yarns.

In addition, the screening and second covering yarns may be used without limitation as long as they are fibers of fineness commonly used in the art, and preferably each independently may have a fineness of 20 to 100De' (denier), more preferably The fineness may be 30 ~ 75De'.

If the fineness of the core yarn and the second covering yarn is independently less than 20De', durability and antibacterial performance according to the single yarn of the silver wire may be deteriorated, and if the fineness exceeds 100De', elasticity may be reduced.

In addition, the second covering yarn may be twisted at a twist number of 350 to 1100 TPM, preferably twisted at 450 to 1000 TPM, and may be included in the ply-twisted yarn. If the number of twists of the second covering yarn is less than 350 TPM, the durability and antibacterial performance according to the single yarn of the silver wire may be deteriorated. In addition, when the number of twists exceeds 1100 TPM, elasticity and flexibility of the third member may be reduced, and as the area of the silver wire exposed to the surface decreases, the antibacterial performance may be relatively reduced.

In addition, the fourth member 154 may be a woven fabric, knitted fabric, nonwoven fabric, or mesh sheet implemented to have a porous structure including the aforementioned silver wire, silver-containing metal wire, and/or ply-twisted yarn. In this case, the woven fabric, knitted fabric, non-woven fabric or mesh sheet may further include natural fiber and/or synthetic fiber that does not contain a silver wire.

Such a filter member 150 may be implemented as a pleated filter in which peaks and valleys are repeatedly formed so as to increase the filtration area.

On the other hand, when the filter member 150 is implemented as a pleated filter, the filter member 150 may be bent so that the height h of the ridge or valley is 5 to 55 mm, preferably It may be bent so that the height of the peak or the valley has a size of 10 to 50 mm.

If the height of the peak or valley is less than 5 mm, the filtration area may be reduced, so that the filtration efficiency may be lowered and the pressure loss may be increased. In addition, when the height of the ridge or trough exceeds 55 mm, the adjacent ridge and ridge or trough and trough adhere to each other, thereby reducing the filtration area, and when the pressure is high, the ridge or valley may be deformed. Here, the height of the ridge or valley means a height difference between adjacent ridges and valleys.

In addition, the filter member 150 may be bent to form 70 to 95 peaks per 300 mm in length, and the size of the filter member is 1.3 to 8.5 m per 300 mm of the installation space in which the filter member is installed. A filter element having a length may be used.

Through this, the filter member 150 can increase the specific surface area compared to the total size of the installation space, so that the removal efficiency is excellent, the pressure loss can be lowered, and the reduction of the removal efficiency can be prevented.

Here, the filter member 150 may be directly coupled to one side of the heat exchanger 140 .

Alternatively, the filter member 150 may further include a filter frame 155 disposed to surround the edge, and may be coupled to one side of the heat exchanger 140 through the filter frame 155 .
