Description

Air purifier {air purifier}

The present invention relates to an air purifying device, and more particularly, in using spray, air purifying efficiency is greatly increased by reliably adsorbing and separating contaminants in the air, and clean air is reliably separated from polluted moisture in the air. It relates to an improved air purifying device so that only purified air can be exhausted into the room.

A technology for purifying air using spraying is disclosed as in the prior art such as Korean Patent Publication No. 10-2020-0115845 described in the patent document of the prior art document.

However, since the above prior art adsorbs and removes pollutants in the air with fine water droplets by a simple spraying technique, not only does the air purification efficiency decrease, but also the efficiency of separation and recovery of fine water droplets adsorbed with pollutants and air decreases. Therefore, some of the fine water droplets adsorbed with contaminants are mixed with the air and exhausted, resulting in a decrease in air purification efficiency.

In addition, an air purifying system such as Korean Patent Laid-open Publication No. 10-2007-0081791 described in patent documents of prior art documents can obtain fine dust adsorption and sterilization effects by using negative ions (Lennard Effect), but negative ions are generated. In the process, ozone that is harmful to the body is generated, and since the air mixed with fine water droplets and ozone is exhausted into the room, it is very harmful to the human body and especially dangerous for infants. Since it is discharged, the humidity in the room increases, which is accompanied by a problem that corrosion or bad phenomena may occur in home appliances or buildings.

Therefore, the present inventors forcibly adsorb fine water particles, fine dust and foreign substances that are sprayed by inhaling indoor air, since negative ions or ozone cannot be generated in principle, and then adsorbed to air and water droplets while passing through an oil-moisture separator. After completely separating foreign substances and fine dust, only the purified air is exhausted into the room, and the contaminated water is reused after purification, so it is inevitably efficient in air purification and has led to research on an air purifier that is very efficient in terms of energy. .

The present invention will be described in more detail based on the accompanying preferred embodiment drawings.

As shown in FIGS. 1, 7 and 10, the air purifying device of the present invention includes an air forced flow means 10 for forcibly transporting air for air purification, and supplying and supplying water for air purification. A water tank (20) for collecting and filtering, a spray collecting means (30) for collecting fine dust or odors in the air by spraying water into the air being forcibly transported, and a large amount of water in the air being forcibly transported Mist adsorption means 40 for adsorbing fine dust or odors in the air by introducing mist particles into the air, separating and removing polluted moisture from the air, and polluting the clean air to be discharged into the room The water separating means 50 and the air separated from the water in the polluted water separating means 50 block the exhaust through the outlet through which the separated water is discharged, and at the same time, the contaminated water is intermittently and automatically removed from the water tank 20. ) It is configured so that various types of air purifying devices are implemented using the air blocking and combined automatic drain means 60 to be discharged.

1 shows the whole of the air purifier of the first embodiment.

Referring to FIG. 1, the air purifier of the first embodiment includes an air forced flow means 10 forcibly transporting air for air purification, and a large amount of mist particles are injected into the forcibly transported air to remove air in the air. It is configured to have a mist adsorption means 40 for adsorbing fine dust or odor and a polluted water separation means 50 for separating and removing polluted moisture from the air and discharging clean air into the room.

In the forced air flow means 10, the air introduced into the air intake pipe 12 is blown to the blower pipe 13 by the blower motor fan 11 in which the fan 11b is rotated by the motor 11a, It is configured to forcefully blow air through a venturi pipe 14 connected to the blower pipe 13, and the venturi pipe 14 has a relatively small diameter relative to the large-diameter pipe 14a and the large-diameter pipe 14b connected to the blower pipe 13. It has a small bore tube 14b.

In addition, in order to supply water to the mist adsorption means 40, direct water may be supplied from a water pipe (not shown) to the water supply pipe 24, and after supplying water to purify the air shown in FIG. A water tank 20 may be further provided so that the collected water and contaminants in a mixed state are filtered.

In the case where direct water is supplied directly from the water pipe (not shown) to the water supply pipe 24, a water level sensor (not shown) is installed at the part receiving water inside the mist generator 40, and an automatic water supply valve (not shown) is installed on the water pipe. (not shown) is installed to apply a water level detection signal to a controller (not shown) so that the automatic water supply valve can be opened and closed so that water can be replenished in the water tank 20, and this automatic water supply technology is already known. Since it is a technique, detailed drawings and descriptions will be omitted.

And in the practice of the present invention, in the lower part of the contaminated water separating means 50, the air separated from the water in the contaminated water separating means 50 is blocked from being exhausted through the outlet through which the separated water is discharged, and at the same time, the contaminated water An air blocking/combining automatic drain means 60 for automatically and intermittently discharging water to the water tank 20 may be further provided.

As shown in FIG. 1, in the forced air flow means 10 according to the present invention, the air introduced into the air intake pipe 12 is blown to the blower pipe 13 by the blower motor fan 11, and the blower pipe 13 ) It is configured to be forcibly blown into the Venturi tube 14 having the large diameter tube 14a and the small diameter tube 14b connected to the venturi tube 14. Reference numeral 12a denotes an air intake. Since the blower motor fan 11 is an off-the-shelf part already known as allowing the fan 11b to rotate with the power of the motor 11a to blow air, detailed drawings and descriptions thereof will be omitted.

Since the motor 11a of the blower motor fan 11 can be controlled by a controller (not shown) to adjust the driving speed, the amount of air blown to the blower pipe 13 by adjusting the rotational speed of the fan 11b can be arbitrarily adjusted.

Therefore, the venturi tube 14 is formed when air is blown from the large-diameter tube 14a connected to the blower tube 13 to the small-diameter tube 14b because the small-diameter tube 14b has a relatively smaller diameter than the large-diameter tube 14a. It serves to further increase the flow rate in (14b).

As shown in FIG. 1, the water tank 20 is configured to have a water return part 22 and a water supply part 23 on both sides around the filter 21, and the water supply part 23 has This is the part where the contaminated water discharged from the air blocking/combining automatic drain means 60, which will be described again, falls and returns water, and the contaminated water in the water return part 22 passes through the filter 21 to the water supply part 23. It is configured to be transmitted to.

Of course, since the water in the water supply unit 22 is supplied to the water pump 31 and the mist generator 41 through the water supply pipe 24, the water in the water supply unit 22 is reduced, so the water return unit 22 The contaminated water passes through the filter 21 and is moved to the water transmission unit 23, and as a result, the polluted water of the water return unit 22 passes through the filter 21 and the contaminants are removed, As it moves to the part 23, clean water can be supplied to the water pump 31 and the mist generator 41.

In addition, although not shown in the drawing, the water tank 20 may be provided with a supplementary water pipe (not shown) connected to the supplementary water tank (not shown) to be further connected. In this case, a water level detection sensor (not shown) is installed in the water tank 20 and an automatic water supply valve (not shown) is installed in the supplementary water pipe so that the water level detection signal is applied to the control unit (not shown) to automatically supply the water valve. Since this automatic water supply technology is a known technology, detailed drawings and descriptions thereof will be omitted. Any type of filter 21 can be used as long as pollutants are filtered, and the filter 21 can be replaced or separated and washed before use. A disinfectant and a diluent are mixed in the water tank 20 Sterilization and poison gas removal can be promoted.

As shown in FIG. 2, in the mist adsorption unit 40, the water of the water transmission unit 23 is supplied to the upper part of the vibration plate 41b, which is vibrated by the ultrasonic vibrator 41a built in the mist generator 41, to vibrate with ultrasonic waves. Mist particles (m) generated by are sucked out through the mist waiting room (41c) and the mist conveying pipe (42) to the small diameter pipe (14b) communicating with the large diameter pipe (14a) of the Venturi pipe (14), and the mist particles (m) It is configured to adsorb contaminants in the air passing through the small diameter tube 14b. Since the ultrasonic vibrator 41a is a known off-the-shelf part and the principle of generating mist particles by ultrasonic vibration is already known, detailed drawings and descriptions will be omitted.

On the other hand, in the present invention, air pollutants are to be named and described as pollutants including all components harmful to the human body such as fine dust, odors, ozone, nitrogen dioxide, carbon monoxide and sulfurous acid mixed in the air.

Therefore, the water (W) filled on the diaphragm (41b) of the mist generator (41) is automatically filled to the same height as the height of the water supply pipe (24) connected to the water tank (20). In some cases, the water supply pipe (24) ) by further attaching an automatic water supply valve (not shown) so that the water (W) on the diaphragm (41b) is automatically filled when it is insufficient. The automatic water supply valve is a known off-the-shelf part.

Therefore, when air is transferred from the large-diameter tube 14a of the venturi tube 14 connected to the blower tube 13 to the small-diameter tube 14b, the small-diameter tube 14b has a relatively smaller diameter than the large-diameter tube 14a. In (14b), since the flow rate is increased, the mist particles (m) in the mist transfer pipe 42 are sucked out as shown in FIG. 2 and mixed with the air transferred to the small diameter tube 14b. m) is in a state in which contaminants such as fine dust or odor in the air are adsorbed.

And, as the mist particles (m) move along with the air through the long small diameter tube (14b), fine dust or odors in the air are further adsorbed to the mist particles (m), and the mist adsorption means (40) In this drawing, only one is shown and described, but in some cases, a plurality of mist adsorption means 40 are installed at equal intervals in the long small diameter pipe 14b to make fine dust or odor in the air more efficiently to the mist particles m It can also be made adsorbable.

On the other hand, as shown in FIG. 1, the present invention includes a dust concentration sensor 70 inside the air inlet 12a or the air intake pipe 12 to detect the concentration of dust in the air and send it to a controller (not shown). and the control unit can be controlled to automatically operate and stop the ultrasonic vibrator 41a of the mist generator 41 of the mist adsorption means 40.

That is, when the dust concentration in the air detected by the dust concentration sensor 70 is higher than the dust concentration set value preset in the controller, the controller operates the mist generator 41 and the air detected by the dust concentration sensor 70 When the dust concentration is lower than the dust concentration set in advance in the control unit, the control unit is controlled to stop the operation of the mist generator 41, and at the same time, the dust concentration in the air detected by the dust concentration sensor 70 is low , Medium, high, the vibration speed of the ultrasonic vibrator 41a of the mist generator 41 may be controlled by the control unit to increase or decrease, and since these control technologies and control circuits are already known, detailed drawings and descriptions are omitted. do.

On the other hand, in order to help the understanding of the present invention, mist particles or fine water droplets adsorbed with fine dust or odor in the air are defined and named as contaminated moisture or contaminated moisture, and the air separated from the contaminated moisture is purified air. Or, it shall be defined, named, and explained as purified air.

Therefore, in the present invention, the air transported through the small bore pipe 14a of the Venturi pipe 14 is forcibly introduced into the contaminated water separation means 50 as shown in FIG. 1, and the contaminated water separation means 50 It performs the function and role of separating polluted moisture such as mist particles or fine water droplets that have absorbed fine dust or odors in the air from pure air.

As shown in FIGS. 3 and 4, the contaminated water separation means 50 has a cyclone chamber 52 inside the water separation cylinder 51 having a conical portion 51b under the cylindrical portion 51a, A whirlwind discharge pipe 56 connected to the small bore pipe 14a is embedded in one side of the upper part of the cyclone chamber 52, but as shown in FIG. ) is configured so that air is discharged in the direction of the circumferential surface, and at the same time, as shown in FIG.

Therefore, the air discharged from the whirlwind discharge pipe 56 rotates along the inner circumferential surface of the water separation container 51 as shown by the arrow shown in FIG. Since it is in a state of rotation, the polluted moisture in the air having a specific gravity higher than that of air moves toward the inner circumferential direction of the water separator container 51 by the centrifugal force of the rotation of the air, and is separated from the air, and the separated moisture as described above (Fine water droplets) stick to the inner circumferential surface of the water separation container 51 and flow down in the direction of the conical part 51b and are discharged to the water discharge pipe 55.

In addition, the air from which polluted moisture is separated as described above is discharged into the room through the filter 53 provided on the upper part of the cylindrical portion 51a to the purified air discharge pipe 54, in which contaminants are removed. It will be.

That is, the polluted water separation means 50 blows the air blown from the small diameter pipe 14a into a whirlwind in the cyclone chamber 52 of the water separation container 51 so that the polluted moisture in the air is removed by the centrifugal force. The separated air is discharged to the lower part and the purified air from which moisture is separated is exhausted through the filter 53 to the purified air discharge pipe 54 so that only clean purified air is supplied to the room.

In addition, since the polluted water separation unit 50 reliably separates pollutant droplets (contaminated water) and pure air to be exhausted to the purified air discharge pipe 54, Purified air is to supply only cleanly purified air with low moisture content to the room.

On the other hand, the polluted moisture in the air moves toward the inner circumference of the water separator 51 by the centrifugal force of air rotation in the contaminated water separation means 50, and is separated from the air and adheres to the inner circumferential surface of the water separator 51. When the amount of contaminated water is large, it becomes water (W) and is discharged through the water discharge pipe 55, so the air blown in a whirlwind in the cyclone chamber 52 is not exhausted through the water discharge pipe 55, but the water separation container ( 51) When the amount of contaminated moisture sticking to the inner circumferential surface is small, the amount of water (W) is small, so the air blowing in a whirlwind in the cyclone room 52 may be exhausted through the water discharge pipe 55, In this case, air containing polluted moisture may be exhausted into the room.

Therefore, the present invention prevents the air of the cyclone chamber 52 from leaking through the water discharge pipe 55 under the contaminated water separation means 50, and at the same time, the contaminated water (W) discharged to the water discharge pipe 55 An air blocking/combining automatic drain means 60 for intermittently draining the water to the water return part 22 of the water tank 20 may be further provided.

5 and 6, the automatic drain means 60 for blocking air has a water inlet 63 connected to the water discharge pipe 55 on the upper part of the float operating room 62 inside the main body 61, and the float (65) On the outer circumferential surface 65a, there are gap projections 67 provided in contact with the inner circumferential surface 62a of the float operating chamber 62 and provided at regular intervals in the circumferential direction, and between the gap projections 67 in the downward direction A water drop path 68 through which water falls is provided, and a valve 66 for opening and closing the drain port 64 is provided at the lower center of the float 65 having a lower specific gravity than water W.

Therefore, when contaminated water flows into the water inlet 63, as shown in FIG. 5, it falls downward along the water drop path 68 provided on the outer circumferential side of the float 65 and accumulates on the upper side of the drain 64 state, and when the water W accumulated in this way gradually increases, the float 65, which has a lower specific gravity than water, floats upward and moves upward, so that the valve 66 is also shown in the imaginary line in FIG. As it moves upward, the drain hole 64 is opened, and the water W is drained through the drain hole 64 to the water return part 22 of the water tank 20 previously mentioned. will be.

And as the water (W) is gradually drained into the opened drain hole 64, the float 65 moves downward again so that the valve 66 automatically blocks the drain hole 64, and as described above, the float (65) The action of collecting and draining water (W) at the bottom is repeated and intermittent.

Therefore, while the valve 66 at the bottom of the float 65 blocks the drain 64, the contaminated air is not exhausted, and while the drain 64 is open, only the water W is drained, so the contaminated air Since the is not exhausted, the air containing the polluted moisture in the cyclone chamber 52 is not exhausted to the room.

Therefore, since the air purifier described in Example 1 generates mist (m) to purify the air, the noise during operation is weak, so it is suitable for use as an air purifier in a room such as a neonatal room or a study room. This will provide a very suitable air purifier.

7 shows an air purifying device according to a second embodiment of the present invention.

7 to 9, in the present invention, the air introduced into the air suction pipe 12 is blown to the blower pipe 13 by the blower motor fan 11, and the venturi pipe 14 connected to the blower pipe 13 ) is provided with an air forced flow means 10 for forcibly blowing air through the large-diameter pipe 14a and the small-diameter pipe 14a.

In addition, a water pump 31 is provided at the bottom of the pumping pipe 32 connected in a right angle direction in the middle of the small diameter pipe 14a, and the water supplied to the water pipe or the water supply pipe 24 of the water tank 20 is supplied to the water pump. Water is pumped by pressure to the nozzle unit 33 connected to the pressure feed pipe 32 by (31) so that the fine water droplets sprayed through the plurality of spray nozzles 35 are supplied to the shower room 36, so that the fine water droplets in contact with the air It is provided with a mist collecting means 30 to collect pollutants in the air.

As shown in FIG. 8, the nozzle part 33 of the mist collecting means 30 has a ventilation hole 33a connected to the small diameter tube 14b of the Venturi tube 14 at the center, and the ventilation hole 33a Inside the outer periphery, there is a circular distribution chamber 34 receiving water supply from the pumping pipe 32, and on one side of the circular distribution chamber 34, water flows in the direction of the shower room 36 connected to the small diameter pipe 14a. A plurality of spray nozzles 35 to be sprayed are configured to be provided at equal intervals in a circumferential direction as shown in FIG.

In addition, the air blown from the small diameter pipe 14a is blown into a whirlwind in the cyclone chamber 52 of the water separator 51 so that the polluted moisture in the air is separated by centrifugal force and discharged to the lower part. The separated purified air is configured to include a polluted water separation means 50 to be exhausted to the purified air discharge pipe 54 through the filter 53.

And in the practice of the present invention, in the lower part of the contaminated water separating means 50, the air separated from the water in the contaminated water separating means 50 is blocked from being exhausted through the outlet through which the separated water is discharged, and at the same time, the contaminated water An air blocking/combining automatic drain means 60 for automatically and intermittently discharging water to the water tank 20 may be further provided.

In the air purifier of the second embodiment, the configuration of the forced air flow means 10, the water tank 20, the contamination separation means 50, and the automatic drain means 60 for blocking air is described in the first embodiment. Since it has the same configuration and operation as the above, detailed description thereof will be omitted.

Therefore, in the present invention, since water is pumped by the water pump 31, water is transferred to the circular distribution chamber 34 in a state of water pressure, so that water is sprayed from a plurality of spray nozzles 35 to the shower room 36. Since the sprayed fine water droplets are sprayed into the air passing through the shower room 36, contaminants such as fine dust or odorous substances in the air are attached to or absorbed by the fine water droplets, thereby being collected in the air. will be in a state of purification.

In addition, the fine water droplets sprayed into the shower room 36 pass through the long small diameter tube 14a together with the air, while contaminants such as fine dust or odorous substances in the air are attached to or absorbed by the fine water droplets. As a result, the air is purified in a cleaner state.

As for the mist collecting means 30, only one mist collecting means 30 is shown and described in FIG. 7, but in some cases, a plurality of mist collecting means 30 are installed at equal intervals in the long small diameter tube 14a. By doing so, it may be possible to more reliably obtain purified air.

On the other hand, in the present invention, the dust concentration sensor 70 is provided in the air intake pipe 12 or in the air intake 12a as shown in FIG. and the control unit can be controlled to automatically start and stop the water pump 31 of the spray collecting means 30. Since the control circuit of the controller (not shown) to be controlled as described above is already known, detailed drawings and descriptions thereof will be omitted.

Therefore, the fine water droplets in which pollutants are collected are transported together with air to the polluted water separation means 50, and clean air and polluted water are automatically separated, and the polluted water becomes condensed water, and the automatic drain means 60 for blocking air and clean purified air is exhausted into the room through the purified air discharge pipe 54. Since the operation of the contaminated water separating means 50 and the automatic drain means 60 for blocking air is the same as that described in Example 1, a detailed description thereof will be omitted.

Therefore, since the air purifier described in the second embodiment can increase or decrease the collection amount of contaminants by adjusting the spray nozzle 35 through which fine water droplets are sprayed into the air passing through the shower room 36, for example, an office It is to provide an air purifying device that is very suitable for use as an air purifying room such as a house or a house.

10 shows an air purifying device according to a third embodiment of the present invention.

In the air purifier of the third embodiment, the air introduced into the air suction pipe 12 is blown to the blower pipe 13 by the blower motor fan 11, and the head of the venturi pipe 14 connected to the blower pipe 13 An air forced flow means 10 is provided to forcibly blow air through the tube 14a and the small bore tube 14a.

In addition, a mist generator 41 is provided at the bottom of the mist conveying pipe 42 connected in a right angle direction to the small diameter pipe 14a, and the water supplied from the water pipe or water tank 20 is built into the mist generator 41 Mist particles (m) supplied to the top of the diaphragm (41b) vibrated by the ultrasonic vibrator (41a) and generated by ultrasonic vibration pass through the mist waiting room (41c) and the mist transfer pipe (42) through the large-diameter tube of the venturi pipe (14). A mist adsorbing means 40 is provided so that contaminants in the air passing through the small diameter tube 14b are adsorbed to the mist particles m by being sucked out through the small bore tube 14b communicating with the small bore tube 14b.

In addition, a water pump 31 is provided at the bottom of the pressure conveying pipe 32 connected in a perpendicular direction to the middle of the small diameter pipe 14a in the direction in which the wind blows around the mist conveying pipe 42, and a water pipe or water tank The water supplied from (20) is pumped by the water pump (31) to the nozzle unit (33) connected to the pumping pipe (32), and the fine water droplets sprayed through the plurality of spray nozzles (35) are sprayed into the shower room (36). It is configured to have a spray collecting means 30 that collects pollutants in the air in fine water droplets that come into contact with the air.

In addition, the air blown from the small bore pipe 14a is blown into a whirlwind in the cyclone chamber 52 of the water separator 51 so that the polluted moisture in the air is separated by centrifugal force and discharged to the bottom The purified air from which moisture is separated is configured to include a polluted water separation unit 50 that exhausts the purified air through the filter 53 to the purified air discharge pipe 54.

And in the practice of the present invention, in the lower part of the contaminated water separating means 50, the air separated from the water in the contaminated water separating means 50 is blocked from being exhausted through the outlet through which the separated water is discharged, and at the same time, the contaminated water An air blocking/combining automatic drain unit 60 may be further provided to automatically and intermittently discharge water into the water tank 20 .

In the air purifying device of the third embodiment, the air forced flow means 10, the water tank 20, the mist adsorption means 40, the contamination separation means 50, and the air blocking and automatic drain means 60 are Since it has the same configuration and same function as that described in the first embodiment, and the mist collecting means 30 has the same configuration and same function as that described in the second embodiment, detailed description thereof will be omitted.

Therefore, in the present invention, contaminants are primarily adsorbed on the mist (m) generated by the mist adsorption means (40), and then contaminants are secondarily added to the fine water droplets generated by the operation of the spray collection means (30). At this time, since the mist (m) particles adsorbed with contaminants are relatively smaller than the sprayed fine water droplets, the mist (m) particles with pollutants adsorbed are primarily absorbed by the sprayed fine water droplet particles. At the same time, since the remaining contaminants that were not primarily adsorbed by the mist (m) are secondarily collected by the fine water droplet particles, more contaminants are collected in the fine water droplet particles, making it more reliable and purified. efficiency will be higher.

On the other hand, in the present invention, the dust concentration sensor 70 is provided in the air intake pipe 12 or in the air intake 12a as shown in FIG. and the control unit automatically controls the water pump 31 of the mist collecting means 30 or the ultrasonic vibrator 41a of the mist generator 41 of the mist adsorption means 40 to operate and stop. .

That is, when the concentration of dust in the air is low, the control unit (not shown) operates only the ultrasonic vibrator 41a of the mist generator 41 of the mist adsorption means 40 to generate fine dust or particles in the air. It can only adsorb odors, and when the concentration of dust in the air is normal, the control unit controls only the water pump 31 of the mist collecting means 30 to operate, so that contamination such as fine dust or odor components in the air Not only can the material be attached to or absorbed by the fine water droplets and collected only by the mist collecting means 30, but also the spray collecting means 30 automatically by the controller (not shown) when the concentration of fine dust in the air is high. The water pump 31 and the ultrasonic vibrator 41a of the mist generator 41 of the mist adsorption means 40 are all simultaneously operated so that fine dust or odor in the air is primarily adsorbed to the mist particles m. After that, it can be operated so that the fine dust or odor in the air is absorbed and collected by the fine water droplets. Since the control circuit of the controller (not shown) to be controlled as described above is already known, detailed drawings and descriptions thereof will be omitted.

Therefore, in the present invention, the mist (m) and fine water droplets in which contaminants are absorbed or collected are transported together with air to the polluted water separation means 50, so that clean air and polluted water are automatically separated, and the polluted water becomes condensate and becomes air. The clean purified air discharged through the automatic drain means 60 for blocking and use is exhausted into the room through the purified air discharge pipe 54. The operation of the polluted water separation unit 50 and the automatic drain unit 60 for blocking air is the same as that described in the first embodiment, and thus a detailed description thereof will be omitted.

Therefore, the air purifier described in Example 3 above is in a state where pollutants in the air are primarily adsorbed to the mist particles (m) and then secondarily collected and removed by fine water droplets, for example, in subways or buildings. To be adopted in an air conditioning system to provide an air purifying device that is very suitable for use as purifying a large amount of air.

On the other hand, since the present inventions described as examples do not generate ozone at all in principle, it is possible to supply purified air that is harmless and safe to the human body, as well as to fine mist particles and fine water droplets sprayed by inhaling indoor air. After forcibly adsorbing and collecting fine dust and foreign substances, it passes through the polluted water separation means to completely separate the polluted water (contaminated condensate) from the air, and only the purified air is exhausted to the room, so the air purification efficiency is improved. In addition, since the contaminated condensate can be reused after purification, water conservation is inevitably efficient, and it is also very efficient in terms of energy. In addition, sterilization and removal of toxic gases are achieved by mixing the disinfectant and diluent in the water tank (20). is also efficient

In addition, since only the purified air in which moisture is separated by the pollutant separation means 50 is supplied to the room in the present invention, purified air containing only a small amount of moisture in the purified air supplied to the room is supplied to the room, and at the same time, the air The automatic drain means 60 for blocking use blocks polluted air containing a lot of moisture from being discharged into the room, and as a result, only purified air with a low moisture content is supplied to the room, so that the spray and water droplets are prevented from being discharged into the room. It is possible to prevent in advance the occurrence of corrosion or bad phenomena in home appliances or buildings due to the increased humidity of the indoor air as it is exhausted into the room.

The present invention is not limited only to what is shown and described in the drawings, and since it may be modified and implemented in various forms by those skilled in the art to which the present invention belongs, it should be widely protected as long as it does not significantly deviate from the scope of the claims.
