Accordingly, as described above, the outdoor air introduced into the second space S2 through the outdoor air inlet I1 passes through the heat exchanger 140 and then through the fourth space S4 to the outdoor air outlet ( O1), and the indoor air introduced into the first space S1 through the indoor air inlet I2 passes through the heat exchanger 140 and then through the third space S3 to the indoor air. It can be discharged to the outside through the air outlet (O2).

As a result, the indoor air moving from the first space S1 to the third space S3 via the heat exchanger 140 passes through the heat exchanger 140 from the second space S2 to the fourth space ( The outdoor air moving to S4) may cross each other inside the heat exchanger 140, and the outdoor air and indoor air respectively introduced into the inner space S may pass through the heat exchanger 140. heat can be exchanged.

Accordingly, even if outdoor air is introduced from the outside to the indoor side through the ventilating air purifier (100, 200) according to an embodiment of the present invention, the outdoor air introduced from the outside into the indoor is transferred from the indoor through the heat exchanger (140). After exchanging heat with indoor air flowing out, it may be introduced into the room.

Through this, the outdoor air introduced into the room from the outside through the ventilation type air purifier 100 or 200 according to an embodiment of the present invention can have a smaller temperature deviation from the indoor air existing in the room.

As a result, even if indoor air is ventilated, outdoor air with a small temperature deviation from indoor air can flow into the room. degradation can be prevented.

Accordingly, when the ventilation type air purifiers 100 and 200 according to an embodiment of the present invention are used, it is possible to minimize the decrease in efficiency of cooling and heating devices such as air conditioners and boilers while supplying fresh outdoor air to the room through ventilation.

Here, the heat exchanger 140 is not limited in its structure as long as heat exchange can occur while the two fluids flowing from the outside to the inside pass through without mixing, and heat exchangers of various known structures can all be employed.

For example, the heat exchanger 140 includes a plurality of support plates 141 formed in a plate shape, as shown in FIG. 20, and a plurality of heat exchange plates formed in a plate shape having a predetermined area and disposed between the two support plates ( 142) may be included.

In this case, each heat exchange plate 142 may include a plurality of peaks and a plurality of valleys formed along the width direction, and the plurality of peaks and valleys may be repeatedly arranged along the longitudinal direction, and may be repeatedly arranged in the height direction. The two heat exchange plates 142a and 142b, which are sequentially arranged along the ridge, may be arranged such that longitudinal directions of peaks and valleys cross each other.

Accordingly, the first space (S1) and the third space (S3) can be in communication with each other through the peaks and valleys formed on one heat exchange plate (142a) of the two heat exchange plates (142a, 142b), The second space S2 and the fourth space S4 may communicate with each other through peaks and valleys formed on the other heat exchange plate 142b of the two heat exchange plates 142a and 142b. In addition, indoor air moving from the first space S1 to the third space S3 via the heat exchanger 140 passes through the heat exchanger 140 from the second space S2 to the fourth space S4. ), and can move in crossing directions without being mixed with each other inside the heat exchanger 140.

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 a corner of the heat exchanger 140 .

To this end, each of the plurality of barrier ribs 123b may include a support groove 123c drawn inward to support an edge of the heat exchanger 140 at one end.

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 cover each corner of the heat exchanger 140 .

Accordingly, when the edge of the heat exchanger 140 is simply inserted into the plurality of support grooves 123c formed in each of the partition walls 123b, the heat exchanger 140 moves through the plurality of support grooves 123c. The inner space S may be partitioned 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 formed through a predetermined area in an area corresponding to one surface of the heat exchanger 140. The through-portion 121a may be sealed through the cover plate 164 detachably coupled to the first inner case 121 as shown in FIGS. 3 and 13 .

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

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

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

Accordingly, outdoor air supplied from the outside to the inside through the operation of the first blower 131 passes through the filter member 150, and foreign substances such as yellow dust or fine dust are removed, and then returned to the main body 120. through the outdoor air outlet (O1) to move to the indoor space, thereby improving the quality of indoor air.

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

Details of the filter member 150 will be described later.

At this time, the filter member 150 may be coupled to one side of the main body 120 via a filter cover 161 detachably coupled to the main 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 passage holes through which air passes, and the first inner case 121 to cover the filter member 150 . ) Can be detachably coupled to one side of.

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 rear surface of the main body 120 When the filter cover 161 is separated from the main body 120 while the cases 112 and 212 are separated, 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 the indoor air discharged from the indoor air outlet O2 formed in the main body 120. Air can be allowed to move to the outside.

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

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

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

For example, the rear case 112 may be coupled to one surface of the main body 120 and may include at least one opening 113 formed through a predetermined area through which outdoor air may pass.

That is, as shown in FIGS. 2 to 4, 9 and 10, the rear case 112 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 at a position corresponding to the cover 161 .

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

Accordingly, outdoor air passes through the rear case 112 through the at least one opening 113 from the outside and passes through the filter cover 161 to the filter member 150 fixed to one side of the main body 120. Outdoor air passing through the filter member 150 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 room through the indoor air inlet I2 may be discharged to the rear surface of the main body 120 through the indoor air outlet O2, and the main body ( Indoor air discharged to the rear surface of 120) may be discharged to the outside through the passage hole 114.

As another example, the rear case 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 case 212 ( 215), and the protrusion 215 may be installed on the wall to pass through the wall defining the indoor space.

Here, the protrusion 215 may be integrally formed with the rear case 212 or may be detachably coupled with the rear case 212 .

In this case, as shown in FIGS. 15 and 16, the inside of the protrusion 215 is divided into a first compartment space 215a and a second compartment space ( 215b).

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

That is, the perforated ventilation type air purifier 200 may further include a vent cover 216 coupled to the rear case 212 to be positioned between the main body 120 and the rear case 212, , The vent cover 216 may connect the second compartment 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, a raised portion 216b protruding from one surface of the support plate 216a, and the It may include a hollow coupler 216c connected to an end of the support plate 216a, and the hollow part of the coupler 216c may communicate with a space defined through the raised portion 216b.

Such a vent cover 216 may be coupled to the protrusion 215 side so that a part of the support plate 216a covers an area corresponding to the second compartment 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 outdoor air moving from the outside through the first compartment space 215a toward the outdoor air inlet I1 of the main body 120 and the vent cover from the indoor air outlet O2 of the main body 120 ( 216), the indoor air moving to the second compartment space 215b can move smoothly along a predetermined path without being mixed with each other.

That is, outdoor air passes through the rear case 212 through the first compartment space 215a from the outside and passes through the filter cover 161 through the filter member 150 fixed to one side of the main body 120. Outdoor air that has passed through the filter member 150 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 room through the indoor air inlet I2 may be discharged to the rear surface of the main body 120 through the indoor air outlet O2, and the main body ( Indoor air discharged to the rear side of the 120) may be discharged to the outside after moving to the second compartment space 215b along the vent cover 216.

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

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

As shown in FIGS. 2 and 13 , the control unit 170 may be disposed on one side of the main body 120 . For example, the controller 170 may be disposed on one side of the second inner case 122 .

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

On the other hand, the ventilation type air purifier (100, 200) according to an embodiment of the present invention is provided with a separate heater (not shown) installed on the moving path of the indoor air or the moving 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 control unit 170 in a state in which operation of any one of the first blower 131 and the second blower 132 is stopped.

Through this, the heater can prevent dew condensation from being generated on a movement path through which the indoor air moves or a movement path through which the outdoor air moves.

In addition, the ventilation type air purifier 100 or 200 according to an embodiment of the present invention may further include an ultraviolet ray generating means 190 capable of irradiating ultraviolet rays toward the outdoor air flowing into the main body 120 from the outside. . For example, the ultraviolet ray generating unit 190 may be a known UV lamp.

As shown in FIG. 8 , the ultraviolet ray generating unit 190 may radiate ultraviolet rays toward the outdoor air before being introduced into the heat exchanger 140 .

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

Through this, the outdoor air introduced into the second space S2 from the outside through the outdoor air inlet I1 is sterilized by the ultraviolet rays irradiated from the ultraviolet light generator 190 and then moves toward the heat exchanger 140. can

Accordingly, since the outdoor air introduced into the heat exchanger 140 does not contain microorganisms such as bacteria, the propagation of bacteria inside the heat exchanger 140 can be prevented.

Meanwhile, the ventilation type air purifier 100 or 200 according to an embodiment of the present invention may further include a filter member (not shown) for filtering indoor air discharged from the inside 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 filter member disposed in the indoor air outlet O2 is not limited thereto, and may be the same type of filter member as the filter member 150 described above, or may be provided as a HEPA filter.

In addition, the filter member disposed at the position corresponding to the indoor air outlet O2 may be provided as a separate member, but may be the filter member 150 described above. That is, the filter member 150 is provided to have an area to cover both the indoor air outlet O2 and the outdoor air inlet I1, so that outdoor air supplied to the indoor space through one filter member 150 and It can also filter all the indoor air exhausted to the outdoors.

Meanwhile, in the ventilation type air purifier 100 or 200 according to an embodiment of the present invention, the first blower 131 and the second blower 132 may be driven to have different operation times.

That is, the control unit 170 determines that the operation time of one of the first blower 131 and the second blower 132 for flowing relatively high-temperature air is the operating time of the other one for flowing relatively low-temperature air. Driving of the first blower 131 and the second blower 132 may be controlled to operate for a longer time.

Through this, in the ventilation type air purifier (100, 200) according to an embodiment of the present invention, even if dew condensation occurs inside the heat exchanger (140) in the process of 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.

Due to this, it is possible to prevent bacteria such as mold from propagating inside the heat exchanger 140 in advance.

As a non-limiting example, as shown in FIG. 26, when the ventilation type air purifier 100 or 200 according to an embodiment of the present invention is driven through a user's manipulation, the control unit 170 operates as a first step (St1). Both the first blower 131 and the second blower 132 may be operated for ventilation.

Accordingly, outdoor air can 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. After being sucked from the indoor space through the heat exchanger 140, it can be discharged to the outside.

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

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

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

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

Through this, relatively high-temperature air among indoor air and outdoor air may be additionally introduced into the heat exchanger 140 for a predetermined time. Due to this, the inside of the heat exchanger 140 can be dried by using the heat of relatively high temperature air, so that dew condensation inside the heat exchanger 140 can be prevented.

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

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

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

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

Accordingly, when the ventilating air purifier (100, 200) according to an embodiment of the present invention is operated, outdoor air in which pollutants such as yellow dust or fine dust are filtered is introduced into the room while discharging indoor air as described above. can Through such ventilation, the concentration of carbon dioxide in indoor air can be lowered, and since pollutants present in the room can be discharged, the indoor air can be maintained in a pleasant state.

In addition, since outdoor air in a state in which antivirus such as Corona 19 is disabled or removed through the filter member 150 can flow into the indoor space, disease occurrence and transmission due to viruses can be prevented in advance.

On the other hand, the filter member 150 for filtering outdoor air is configured to inhibit the growth of bacteria, fungi, viruses, etc., so that contamination of the heat exchanger can be prevented while preventing bacteria and viruses from entering the room.

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

The first member 151 is an electrostatically treated porous member, and may be a filtering material through which outdoor air primarily passes. The first member 141 filters fine dust and dust contained in the air using electrostatic force. can do. For example, the first member 151 may be a known nonwoven fabric, preferably a meltblown nonwoven fabric.

Here, the electrostatic treatment may be performed on the entire area of the first member 151, but may also be performed on only a portion of the entire area of the first member 151, and in the manufacture of a typical electrostatic treatment filter A known method to be used can be appropriately employed.

In addition, the first member 151 can adjust the diameter and basis weight of the fiber according to the purpose, and to ensure improved filtration performance and durability, the first member 151 is a fiber having a diameter of 1 to 10 μm It may include, the basis weight of the first member 151 may be 15 ~ 50g / ㎡, in another example, the basis weight may be 20 ~ 35 g / ㎡. In addition, the average hole diameter of the first member 151 may be 20 μm or less, for 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, the filtration efficiency may decrease.

In addition, when the average diameter of 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, the filtration efficiency may decrease.

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

Meanwhile, the fiber 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 passing 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 a nanofiber web 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 an electrospinning component.

The hole 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 prevent a decrease in the flow rate of air passing therethrough. Euros may be included.

The second member 152 composes the filter member 150 together with the above-described first member 151 to compensate for the problem of reduction in collection efficiency due to static elimination that may occur in the electrostatically treated first member 151. It can maintain the designed filtration efficiency even for a long time.

That is, the electrostatically treated first member 151 uses electrostatic force to adsorb dust to the fiber surface, and the electrostatic force decreases as time passes. Accordingly, when the filter member 150 is composed of only the electrostatically treated first member 151, the filtering efficiency of the filter member 150 decreases over time, so there is a problem in 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 a filter member composed of only the first member 151, Even after several months, the collection efficiency can maintain 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 have 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 suppress the proliferation of the virus, destroy the virus itself, or block infection by participating in the mechanism by which the host is infected by the virus.

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

Here, the meaning of direct or indirect may mean that the antiviral motif directly performs the corresponding function or is involved in a starting or intermediate process in the eventual performance of 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 virus described above.

As a non-limiting example, the antiviral motif is any one peptide selected from the group consisting of the amino acid sequences of SEQ ID NO: 1 to SEQ ID NO: 7, a peptide in 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 an amino acid sequence of more than one species as a basic sequence.

Here, the motif according to SEQ ID NO: 1 and 2 may be useful for SARS corona virus, the motif according to SEQ ID NO: 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 there is.

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 to known viruses, 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 nanofibrous web by itself without forming a fusion protein, but it may be difficult to fix only the antiviral motif in the nanofibrous 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 conjugate protein, and it can be provided on the fiber web or the fiber surface forming the fiber web.

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

On the other hand, the antiviral motif and adhesive protein can be combined through a known method, and for example, it can be prepared through a recombinant protein production method using E. coli. Meanwhile, although the adhesive protein and the antiviral motif may be directly covalently bonded, it is not limited thereto and may be indirectly bonded 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 adhesive function, but may be, for example, a mussel-derived adhesive protein, and a known adhesive protein collectively referred to as a mussel-derived adhesive protein may be used without limitation. there is. Preferably, the adhesive protein may be any one protein selected from the group consisting of amino acid sequences of SEQ ID NO: 8 to SEQ ID NO: 21 or a protein linked to one or more amino acid sequences selected from the above group.

In addition, the adhesive protein is 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 described later, to implement a coating layer in the form of an aggregate. 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 disabling of antiviral motifs due to decomposition, denaturation, etc. at room temperature for a long time, 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 waveguide moiety in order to express a more improved fibrous web or adhesion characteristics with the fiber surface forming the fibrous web. Mussel adhesive proteins are known to have adhesive properties, but as a result of research by the present inventors, when these adhesive proteins are used as they are, they show no or insignificant adhesive properties, making it difficult to fix the antiviral motif on the substrate surface. .

In order to improve this, it can be modified to contain a waveguide moiety in the adhesive protein, and in this case, improved adhesive performance can be expressed. The modification is to modify some or all of the tyrosine residues contained in the adhesive protein into waveguide residues, and this modification can be performed using a known method appropriately. For example, the modification may be performed using an enzyme, and the enzyme may be, for example, tyrosinase.

Describing the method for modifying tyrosine residues into dopa residues using tyrosinase, antiviral fusion proteins with adhesive proteins are mixed with 20-100 mM sodium acetate containing 25-100 mM ascorbic acid and 20-100 mM sodium borate. After dissolving it in a buffer solution to a concentration of 0.01 ~ 10 mg / ml, injecting oxygen for 10 ~ 1 hour to saturate the oxygen in the solution, and then adding tyrosinase to a final concentration of 10 ~ 50 μg / ml After mixing and stirring under oxygen conditions for 30 minutes to 2 hours, the reaction was terminated by adding acetic acid to a final concentration of 2 to 10%, and the finished reaction solution was desalted and concentrated with a 1 to 10% acetic acid solution, followed by lyophilization. Through this, a dopa-modified antiviral fusion protein in powder form can be obtained.

The antiviral fusion protein containing the waveguide moiety prepared through the above-described method can be easily fixed on the fiber web or the fiber surface forming the fiber web without any other adhesive component, and as no other adhesive component is used, the antiviral fusion protein can be easily fixed. Unintended chemical reactions between ingredients and antiviral motifs, and 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 or inorganic material. For example, the heterogeneous material may be an inorganic material in which a proton-donating or proton-accepting substituent is disposed on the surface that the virus contacts, and specific examples include a phosphoric acid compound of a titanium group element such as zirconium phosphate, hafnium phosphate, titanium phosphate, and 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 metal such as silver or a salt containing an ion thereof.

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

The antiviral coating composition may further include a solvent for dissolving the antiviral component or a buffer solution for stabilizing, in addition to the above-described antiviral component including the antiviral fusion protein. The solvent may be water and/or an organic solvent, and a 20 to 100 mM Tris or sodium bicarbonate 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, for example, 0.001 to 0.1 mg/ml, and if contained at a high concentration, antiviral properties may be improved, but However, the coating composition can block the pores of the fibrous web to which it 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 waveguide moiety can improve the adhesion of the implemented antiviral coating layer, but requires additional cost, time and effort due to modification, so the present invention An 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 without modification of adhesive proteins in the coating composition.

The aggregation-inducing component is a substance that introduces an antiviral fusion protein to the surface of a substrate, and is an antiviral fusion protein in preparation for the case where the fiber web or the fiber surface constituting the fiber web is treated with the antiviral fusion protein alone using a conventional method. It is possible to improve the adhesion between the coating layer of and the surface.

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 on the surface of the substrate to form an aggregate. A coating composition using an aggregation-inducing component can enhance the adhesion of antiviral fusion proteins, and can stably maintain its shape and activity even when external temperature or humidity changes, so it has excellent storage stability and friction fastness, and is antiviral. The effect can last for a long time.

On the other hand, the antiviral coating layer implemented through the antiviral coating composition containing an aggregation-inducing component may include a carbodiimide-based compound, wherein the carbodiimide-based compound is the above-described carbodiimide coupling agent contained in an adhesive protein. It can remain in the antiviral coating layer through being bonded to a hydroxy 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 believe that it is due to a specific chemical bond between the fusion proteins, for example, an amino bond between a carboxy group and an amine group by a conventionally known carbodiimide coupling agent. , This is because a plurality of hydroxy groups and sulfone groups included in adhesive proteins, for example, mussel-derived adhesive proteins, can also react with carbodiimide coupling agents. Therefore, it is difficult to see that the granule form formed by the antiviral fusion protein according to the present invention having multiple reaction sites is caused by any specific reaction and the resulting chemical bond, and it is difficult to see that it is caused by the combination between the aggregation component and the antiviral fusion protein. can be seen as a result of

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

In addition, the reactant is provided to prevent antiviral fusion proteins coupled with carbodiimide from being hydrated to increase the efficiency of aggregation of antiviral fusion proteins, for example, N-hydroxysuccine It may be one of mead (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 concern that the durability of the antiviral coating layer implemented and the activity of the antiviral motif may deteriorate.

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 aggregation component described above may be added to the coating composition as a liquid phase dissolved in a solvent. At this time, water or an organic solvent may be used as a solvent, preferably water and / or ethanol may be used, and coating Ethanol may be used as a solvent in terms of increasing the volatilization rate of the solvent in the composition. If the evaporation 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 on the surface of the fiber web or fibers forming the fiber web.

On the other hand, if the coating composition further includes 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 surface of the fiber web or the fiber forming the fiber web. Formation of an antiviral coating layer may be difficult when the fiber web or the fiber surface forming the fiber web is treated after excessive progress beyond a certain level. 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, low temperature conditions.

Alternatively, in order to further improve storage stability, the antiviral coating composition may be composed of a two-component coating composition including 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 or hydrogen peroxide, through which 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 that expresses antiviral performance by combining a functional group or the like included in the surfactant with a virus 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, and 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, may also be used, in addition to cationic, antiviral, Amphoteric surfactants may also be used.

The third member 153 may be a porous member that performs 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 side of the second member 152.

At this time, the third member 153 is not particularly limited as long as it is a porous member that normally serves as a support.

For example, the third member 153 may be woven, knitted, or 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. In addition to this, 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 by including a known component having antibacterial properties, but may preferably be formed of fibers containing silver exhibiting antibacterial properties.

The silver-containing fiber may be a silver wire composed of only silver, a metal wire containing other metals such as copper in addition to silver, or a ply-twisted yarn in which silver wire and/or a metal wire containing silver and conventional non-metal fibers are plied. there is.

A metal wire containing another metal such as copper may be formed in a linear shape by mixing a metal other than silver with silver in a non-solid-solution state, that is, in a non-alloy state. When a metal other than silver is mixed with silver in a non-solid solution state, the silver and the other metal may be arranged so that the silver and the other metal occupy a predetermined area regularly or irregularly in a linear area, respectively, For example, it may have a double structure in which silver is surrounded on the outside of a copper wire to form a layer.

At this time, the copper wire may impart excellent flexibility to the silver wire, and the average thickness of the surrounding silver may be 3 to 3200 nm, preferably 5 to 3000 nm. If the average thickness of the surrounding silver is less than 3 nm, the central metal, copper, may be easily manufactured to be exposed to the outside, and the antibacterial function may be deteriorated, and the silver may be detached from the silver wire, further deteriorating the antibacterial function. In addition, if the average thickness of the surrounding silver exceeds 3200 nm, the flexibility of the silver wire may deteriorate.

Next, a plied yarn in which a silver wire is plied with a non-metallic conventional fiber is described. The silver wire and the conventional fiber are a known fiber manufacturing method in which two kinds of fibers are plied, and a known arrangement structure of two kinds of fibers. It may be a ply-twisted 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 has a triple structure cross section including a core, a first covering yarn including a silver wire surrounding the core, and a second covering yarn surrounding the outside of the first covering yarn surrounding the core. can

Any fiber that can be used to improve the flexibility and elasticity of the ply-twisted yarn can be used without limitation, preferably at least one selected from natural fibers and synthetic fibers, and more preferably poly Ester fibers may be used.

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

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

If the fineness of the screening yarn and the second covering yarn are each independently less than 20De', durability and antibacterial performance according to the single yarn of the silver wire may decrease, and if the fineness exceeds 100De', elasticity may decrease.

In addition, the second covering yarn may be twisted with a twist number of 350 to 1100 TPM, preferably twisted with a twist of 450 to 1000 TPM and included in the ply-twisted yarn. If the number of twists of the second covering yarn is less than 350 TPM, 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 decrease, and as the area of the silver wire exposed to the surface decreases, antibacterial performance may decrease.

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

Such a filter member 150 may be implemented as a pleated filter having peaks and valleys repeatedly formed so as to increase the filtering area.

On the other hand, when the filter member 150 is implemented as a pleated filter, the filter member 150 may be formed by bending such that the height (h) of the crest or valley has a size of 5 to 55 mm, preferably It may be formed to be bent to have a height of 10 to 50 mm in the height of the crest or valley.

If the height of the crest or valley is less than 5 mm, the filtration area may be reduced and the filtration efficiency may be reduced and the pressure loss may be increased. In addition, if the height of the crest or valley exceeds 55 mm, adjacent crests and crests or crests and valleys stick to each other, reducing the filtration area, and if the pressure is high, the crest or valley may be deformed. Here, the height of the hill or valley means a difference in height between neighboring hills 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 in length of the installation space in which the filter member is mounted. A filter element having a length may be used.

Through this, the specific surface area of the filter member 150 can be increased compared to the total size of the installation space, so that the removal efficiency is excellent, the pressure loss can be reduced, and the reduction in 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 an edge as shown in FIG. It may be coupled to one side of the heat exchanger 140.
