Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mist generating device, and more particularly to a mist generating device provided with a gas-liquid contact portion and a droplet separating portion, and purifying air or the like using fine water droplets (mist) discharged from the droplet separating portion. The present invention relates to the improvement of air purifiers.

[0002]

2. Description of the Related Art A conventional air purifier of this type is, for example, shown in FIG.
It is configured as shown in FIG. In FIG. 1, reference numeral 1 denotes a fan for forcibly sucking air in a space to be purified (room), which is arranged at an arbitrary portion of an air flow path (for example, a duct). An air suction port is formed at one end of the duct, and a filter 2 for removing dust and the like having a relatively large particle size is arranged at the air suction port. A gas-liquid contact part 3 is connected to the other end of the duct. The gas-liquid contact part 3 is formed in a cylindrical shape, and a pipe is provided upright at the axial center thereof, and a plurality of spray nozzles 4 for spraying water to a predetermined part are radially arranged. A droplet separation unit 6 is disposed adjacent to the gas-liquid contact unit 3 via a communication port 5. The droplet separating section 6 is formed in a cylindrical shape, and has an outlet 7 for cleaning air, mist and the like formed at an upper portion thereof. A pump 8 for water injection is connected to a lower end of a pipe erected at the axial center of the gas-liquid contact part 3. In particular, a water tank 10 for storing water supplied from a water supply tank 9 is provided below the gas-liquid contact section 3 and the droplet separation section 6, and the water stored in the water tank 10 is piped by a pump 8. Injection nozzle 4 through
From the gas-liquid contact part 3.

[0003] The air purifier thus configured operates as follows. In the state of FIG. 8, when the fan 1 is first rotated and driven, the air in the room is sucked into the duct through the filter 2. At this time, dust having a large particle diameter sucked together with the air is prevented from flowing into the duct by the filter 2. The air sucked into the duct is sent to the gas-liquid contact part 3. In particular, since this air is introduced along the inner wall surface of the cylindrical portion of the gas-liquid contact portion 3, it descends while turning along the inner wall surface of the gas-liquid contact portion 3.

On the other hand, the water stored in the water tank 10 is pumped through the pipe by the pump 8 and is injected from the injection nozzle 4 toward the inner wall surface of the gas-liquid contact part 3. The fine water droplets jetted from the jet nozzle 4 are further miniaturized by colliding with the inner wall surface of the gas-liquid contact part 3, and at the same time, descend while rotating while contacting and mixing with the circling air, The liquid is introduced into the droplet separation section 6 from the communication port 5. In addition, when fine water droplets ejected from the ejection nozzle 4 collide with the inner wall surface of the gas-liquid contact part 3, a large amount of negative ions are generated. In addition, due to the contact between the air and the fine water droplets, most of the fine dust, tobacco smoke, ammonia odor and the like contained in the air adhere to the water droplets. Water droplets to which dust or the like adheres have various particle diameters according to the size of the dust or the like, and are increased in diameter from the beginning. In particular, water droplets having a large particle diameter cannot be swirled due to the swirling force applied to the mixture of air and water droplets, and fall or collide with the inner wall surface of the gas-liquid contact portion 3 and travel along the inner wall surface to form a water tank portion. Runs down to 10.

Next, a mixture of air containing negative ions introduced into the droplet separation section 6 and fine water droplets (mist) includes:
Since the exhaust port 7 is formed in the upper part of the droplet separating section 6, a swirling force effectively acts. For this reason, the air-fuel mixture rises while swirling along the inner wall surface of the droplet separation section 6. At this time, since the centrifugal force of the swirl acts on the air-fuel mixture, only the air-fuel mixture containing a mist of water, which is considered to be free of dust, swirls and rises, for example, fine dust adheres. Water droplets with a particle size of several tens of μm or more, which have no or no dust attached, are separated from the mixture,
It falls into the water tank 10 and is collected. Then, the air-fuel mixture containing the mist of purified air and water is continuously discharged from the exhaust port 7 into the room, thereby promoting the cleaning of the room. Note that the particle size distribution of the mist discharged from the exhaust port 7 is mainly composed of particles having a particle size of about 0.5 μm or less.

According to the air cleaner configured as described above, the air-fuel mixture containing the mist of the purified air and water is continuously discharged from the exhaust port 7 into the room, thereby purifying the room. Although it is promoted, especially when the mist circulates in the room, finer debris in the air, smoke and smell of cigarettes, etc. are taken and sucked into the air purifier again, so higher quality cleaning is performed. Can be expected, and furthermore,
A large amount of negative ions are generated when water injected from the injection nozzle 4 collides with the inner wall surface of the gas-liquid contact part 3 and is miniaturized. Therefore, the state close to the natural environment near a forest or a waterfall. Can be realized, and a refreshing feeling of mind and body can be obtained.

[0007]

However, when this air purifier is used indoors, as described above, fine dust in the air sucked together with air and mist from the room, smoke and odor of cigarettes as described above. The water in the water tank section 10 is used for a long period of time because the water and the like fall into the water tank section 10 by being mixed with the water injected from the injection nozzle 4 in the gas-liquid contact section 3 and are collected. Get dirty gradually. While the dirt of the water is slight, even such water is pumped inside the pipe by the pump 8 and is injected from the injection nozzle 4 toward the inner wall surface of the gas-liquid contact portion 3, so that the water is again taken in from the room. The water is mixed with fine dust in the air, and water droplets having a large particle diameter attached to the dust are removed, and purified air, mist, and the like are supplied to the room through the droplet separation unit 6. .

However, the air introduced into the gas-liquid contact part 3 may contain bacteria and molds in addition to fine dust and tobacco smoke. Propagate when the conditions are met when mixed in the water of
Water quality will be impaired and algae will be generated. In particular, when bacteria, molds, and the like are ultra-fine, for example, 1 to 2 μm or less, water containing them is sprayed from the spray nozzle 4 and is contacted with and mixed with air, but the gas-liquid contact portion 3 and the droplets Even if centrifugal force due to swirling acts on the air-fuel mixture in the separation unit 6, it may not be possible to separate mist containing ultra-fine bacteria, molds, etc. from the air-fuel mixture.
For this reason, the supply function of fresh and purified mist and the like from the air cleaning device into the room is reduced, and the cleaning function is also impaired.

Therefore, conventionally, in order to solve such a problem, the water in the water tank section 10 is changed a little earlier. However, the water is frequently changed and the maintenance becomes troublesome. It is. On the other hand, if the frequency of replacement is reduced, the above-described problem occurs.

[0010] Therefore, an object of the present invention is to provide a mist generating device that can facilitate maintenance and the like with a relatively simple configuration.

[0011]

Below the gas-liquid contact part D and the droplet separation part E, a second water tank part F which is separated from and independent of the first water tank part B is arranged. On the side, a second water supply tank G is arranged so that water can be supplied to the second water tank F.

The pre-washing section A includes a fan 1 and a filter 2
This is a part that preliminarily cleans dust, bacteria, molds, etc., contained in the air in the space to be purified,
For example, there is a portion for introducing air in the space to be purified above,

In addition, an opening is formed below the cylindrical body 20,
It is connected to the gas-liquid contact part D via the connecting pipe 24.

The gas-liquid contact section D connected to the pre-wash section A by the connecting pipe 24 further cleans the air-fuel mixture containing air and mist sent from the pre-wash section A and generates mist and negative ions. For example, the connecting pipe 24 is connected to the opening formed below, and the lower end is the second pipe.
Cylindrical body 3 erected so as to be immersed in the water of the water tank portion F
0 and a pipe 31 arranged at the center of the tubular body 30
A plurality of water injection nozzles 32 radially arranged on the outer peripheral surface of the pipe 31;
And a pump 33 for pressure-feeding the oil.
Note that an opening is formed above the cylindrical body 30, and is connected to the droplet separation unit E via a connection pipe 34.

The liquid drop separating section E connected to the gas-liquid contact section D by the connecting pipe 34 separates large liquid drops in the air-fuel and air-mist mixed gas sent from the gas-liquid contact section D,
It is a part that generates an air-fuel mixture containing finer mist,
For example, the connecting pipe 34 is connected to the opening formed at the upper part, and the lower end is erected in the water of the second water tank part F. To
A space through which the air-fuel mixture can flow is formed between the lower end 41a and the water in the second water tank F, and the air-fuel mixture discharge pipe 4 is arranged such that the upper end 41b is opened to the space to be purified.
And 1.

The first water tank B and the second water tank F have a first water tank C and a second water tank C, which are disposed on respective sides thereof.
The water supply tank G is configured to supply water so as to have a substantially constant water level. For example, the first water supply tank C is provided with a mounting portion of the lid 51 disposed in the first water tank portion B. 5
2, and the supply of water to the first water tank B is controlled by a water supply valve 50. The arrangement of the second water supply tank G in the second water tank F is the same as the arrangement of the first water tank C in the first water tank B. When water cannot be supplied from each water supply tank to each water tank section, the operation of the apparatus is stopped by, for example, a water level detection device (not shown) or an alarm means such as a lamp or a buzzer is activated. It is configured. still,
The mounting portion 52 of the water supply tank is configured in a funnel shape, for example.

Next, the operation of the mist generating device will be described with reference to FIGS. First, when the apparatus is driven, the fan 1 is rotated, and air in the space to be purified (room) is filtered through the filter 2 and the duct.
Will be introduced. In particular, since this air is introduced along the inner peripheral surface of the cylindrical body 20, it descends while turning along the inner wall surface 20a thereof. At the same time, the water stored in the first water tank B is pumped to the pipe 21 by the pump 23, and the inner wall 2 of the cylindrical body 20 is discharged from the plurality of nozzles 22.
Injected toward 0a. Fine water droplets jetted from the nozzle 22 are further miniaturized by colliding with the inner wall surface 20a of the cylindrical body 20. Then, it comes into contact with and mixes with the circling air and descends while circling.
4 to the gas-liquid contact part D. The nozzle 22
Water droplets sprayed from the inner wall surface 20a of the cylindrical body 20
When a collision occurs, a large amount of negative ions are generated. Moreover,
Due to the contact between the air and the fine water droplets, many bacteria, molds, fine dust and the like that cannot be removed by the filter 2 and are contained in the air adhere to the water droplets. Water droplets to which dust or the like adheres have various particle diameters according to the size of the dust or the like, and are increased in diameter from the beginning. In particular, water droplets having a large particle size cannot be swirled by the swirling force applied to the mixture of air and water droplets, and fall, or the inner wall surface 20a of the cylindrical body 20
And flow down to the first water tank B to be collected.

The air-fuel mixture containing air which has been preliminarily cleaned in the pre-washing section A is introduced through the connecting pipe 24 along the inner peripheral surface of the cylindrical body 30 in the gas-liquid contact section D.
It rises while turning along its inner wall surface 30a. At the same time, the water stored in the second tank section F is supplied to the pump 3
The pressure is fed to the pipe 31 by the nozzle 3, and is jetted from the plurality of nozzles 32 toward the inner wall surface 30 a of the tubular body 30. Fine water droplets ejected from the nozzle 32 are further miniaturized by colliding with the inner wall surface 30a of the cylindrical body 30. Then, the liquid is brought into contact with and mixed with the circling air, rises while circling, and is sent out to the droplet separation unit E via the connecting pipe 34. When fine water droplets ejected from the nozzle 32 collide with the inner wall surface 30 a of the cylindrical body 30, a large amount of negative ions are generated and are added to the negative ions generated in the pre-wash section A. In addition, due to the contact between the air and the fine water droplets, many fine dusts and the like that could not be removed in the pre-washing section A are again attached to the water droplets. As a result, the diameter of the water droplets adhering to the dust is increased from the beginning. As a result, the water droplets cannot be swirled due to the swirling force applied to the air-fuel mixture and fall or collide with the inner wall surface 30a of the cylindrical body 30. It flows down to the water tank section F and is collected.

A mixture containing fine water droplets (mist) from which water droplets whose diameter has been increased due to the adhesion of fine dust and the like, purified air, and negative ions is passed through a connecting pipe 34 to a droplet separation section E. It is introduced into the cylindrical body 40, and descends while turning around the space formed between the inner wall surface 40 a of the cylindrical body 40 and the discharge pipe 41 using the discharge pipe 41 as a guide. At this time, for example, water droplets having a particle size of several μm or more are separated from the air-fuel mixture and collected in the second water tank portion F. Such an air-fuel mixture is introduced into the inside from the lower end opening 41a of the discharge pipe 41, and is discharged into the room through the upper end opening 41b. The mist released into the room is cleaned by repeating a cycle in which fine dust and tobacco smoke and odor in the air are captured and returned to the pre-washing section A via the filter 2 again, thereby reducing the indoor environment. Be improved.

According to this embodiment, before the air sucked from the room by the fan 1 is introduced into the gas-liquid contact section D, bacteria, fine dust and the like contained in the introduced air are preliminarily collected in the pre-wash section A. As a result, the amount of bacteria, fine dust and the like contained in the air-fuel mixture introduced into the gas-liquid contact portion D can be significantly reduced. Therefore,
The purified air-fuel mixture can be discharged from the droplet separation section E into the room, and a high-quality cleaning function can be exhibited.

Further, in the pre-washing section A and the gas-liquid contacting section D, the water in the first water tank section B and the second water tank section F, which are separated and independent from each other, are used separately. The contamination of the water in the second water tank section F by the gas mixture introduced from A into the gas-liquid contact section D can be remarkably reduced, and the gas mixture purified over a long period of time can be generated. Can continue to be sent.

Since the water in the first water tank B associated with the pre-washing section A progresses at a rapid rate, it is necessary to change the water at an early stage. Since the structure in A is simpler than the structure of the gas-liquid contact portion D including the second water tank portion F and the structure of the droplet separation portion E, the water can be exchanged relatively easily, The maintainability can be improved as compared with the conventional device.

In particular, in the first water tank section B, preferably in the second water tank section B,
If an ultraviolet ray generating device (for example, a UV lamp) is disposed in the water tank section F or a photocatalytic action is used, the propagation of bacteria and molds can be suppressed, and the deterioration of water quality and the progress of contamination can be suppressed. The frequency of water exchange can be reduced.

Basically, the pre-washing section A and the gas-liquid contact section D have the same air-fuel mixture generation mechanism.
Negative ions are generated at both the gas-liquid contact portion D and the gas-liquid contact portion D. These negative ions are added at the gas-liquid contact portion D and sent to the droplet separation portion E. Therefore, the amount of negative ions discharged into the room from the droplet separation section E can be increased to about twice as compared with the case where only the gas-liquid contact section D is used, and is close to the natural environment near a forest or a waterfall. The state becomes feasible, and the exhilaration of mind and body can be further obtained.

In particular, the amount of negative ions can be determined by forming the cylindrical members 20 and 30 by a metal member or by adjusting the inner wall surface 2 against which water collides.
It can be increased by sticking or plating a metal member on the portions 0a and 30a, and the above-mentioned effect can be further promoted.

Further, in winter, it is conceivable that dew may be formed on the indoor wall surface.
For example, when the room temperature falls below 15 ° C., the water in the first water tank B and the second water tank F is heated by a heater or the like,
By heating so as to be higher than room temperature by about 1 to 2 ° C., dew condensation on the wall surface can be reduced.

FIG. 4 shows a second embodiment of the mist generating apparatus according to the present invention.
This is the same as the embodiment shown in FIG. The difference is that
a is simplified, and specifically, the fan 1
The end of the duct extending from the first water tank B is disposed in the water of the first water tank B, and the first water tank B is substantially sealed and connected to the gas-liquid contact part D by the connecting pipe 24.

According to this configuration, the air in the room sucked by the fan 1 is first filtered through the filter 2 and the duct.
When water is blown out into the water in the water tank section B and discharged to the connecting pipe 24 through the water, bacteria, fine dust and the like contained in the air are preliminarily washed and removed by the water.
The amount of bacteria, fine dust and the like contained in the air-fuel mixture introduced into the gas-liquid contact portion D can be significantly reduced. Therefore, the purified air-fuel mixture can be discharged from the droplet separation section E into the room, and a high-quality cleaning function can be exhibited.

Further, the pre-washing section Aa has a simplified structure because the nozzles, pumps and the like are omitted as compared with the first embodiment, so that the pre-washing section Aa can be easily cleaned and the cost is reduced. Reduction is also possible.

In this embodiment, the gas-liquid contact portion D
It is desirable to provide a fan alone or in addition to the connecting pipe 24 or in the vicinity thereof in order to impart a further turning force to the air introduced into the air.

FIG. 5 shows a third embodiment of the mist generating apparatus according to the present invention.
This is the same as the embodiment shown in FIG. The difference is that
(b) The rotary bucket method is adopted as the means for miniaturizing water in the gas-liquid contact part Da.

Specifically, the pre-washing section Ab includes, for example, a cylindrical body 20, a pipe 21 arranged at the upper central portion of the cylindrical body 20, a nozzle 22 arranged at a lower end of the pipe 21,
A first pump 23 for pumping the water in the first water tank section B to the pipe 21 and the nozzle 22 (for example, a pressure of about ² kg / cm ² ); It comprises a rotating body 25 having a substantially bowl shape (bucket) having a reference numeral 25a, and a motor 26 for applying rotation to the rotating body 25 via a rotating shaft 27. The gas-liquid contact portion Da has basically the same configuration as the pre-washing portion Ab. For example, the tubular member 30, the pipe 31 disposed at the upper central portion of the tubular member 30, and the lower end of the pipe 31 are disposed. The nozzle 32 and the water in the second water tank section F are supplied to the pipe 31 and the nozzle 32.
Pump 33, which is disposed under the nozzle 32, a substantially bowl-shaped rotator 35 having a plurality of holes 35a only in the side wall portion, and the rotation of the rotator 35 via a rotation shaft 37. And a motor 36 to be provided.
The rotation speed of the motors 26 and 36 is, for example, 2800 to 3
It is desirable to set it in the range of about 200 rpm,
It is also possible to set outside this range depending on the situation.

This mist generator operates as follows. Note that the droplet separation unit E is the same as in the first embodiment, and a description thereof will be omitted. First, in a state where the indoor air is being introduced into the tubular body 20 of the pre-washing section Ab by the fan 1, the motor 26 is driven via the rotating shaft 27 by the rotating body 25.
, The rotating body 25 rotates in a specific direction at a predetermined speed. At this time, the water pumped by the pump 23 is discharged from the nozzle 22 to the rotating body 25 via the pipe 21. The water discharged into the rotating body 25 is miniaturized by the centrifugal force of the water, and jumps out of the hole 25a in the side wall portion. Further, the water collides with the inner wall surface of the cylindrical body 20 and is further miniaturized. At this time, a large amount of negative ions are generated. When the micronized water droplets come into contact with air introduced from the room, they take in bacteria, fine dust, smoke of tobacco, and the like contained in the air, and swirl inside the cylindrical body 20 to descend. During this downward movement, water droplets whose diameter has been increased from the beginning due to the incorporation of fine dust or the like cannot be swirled due to the swirling force applied to the mixture of air and water droplets, or fall, or It collides with the inner wall surface and flows down to the first water tank B to be collected.

The air-fuel mixture containing air which has been preliminarily cleaned in the pre-washing section Ab is introduced through the connecting pipe 24 along the inner peripheral surface of the cylindrical body 30 in the gas-liquid contacting section Da. It rises while turning along its inner wall. At the same time, the water stored in the second water tank F is
, And is discharged to the rotating body 35 from the nozzle 32. The water discharged into the inside of the rotating body 35 is miniaturized and pops out from the hole 35a of the side wall portion due to the centrifugal force of the water, and collides with the inner wall surface of the cylindrical body 30 to be further miniaturized. At this time, a large amount of negative ions are generated. Then, the liquid is brought into contact with and mixed with the circling air, rises while circling, and is sent out to the droplet separation unit E via the connecting pipe 34. Note that negative ions generated in the process of generating fine water droplets by the rotation of the rotating body 35 are:
It is added to the negative ions generated in the prewash section A. In addition, due to the contact between the air and the fine water droplets, many fine dusts and the like that could not be removed in the pre-washing section A are again attached to the water droplets.
Water droplets attached to garbage and the like are enlarged from the beginning,
Due to the swirling force applied to the air-fuel mixture, the air-fuel mixture cannot be swirled and falls, or collides with the inner wall surface of the tubular body 30 and flows down into the second water tank portion F to be collected.

According to this embodiment, since the rotating body 25 is rotated at a high speed in the prewashing section Ab, water is miniaturized when jumping out of the plurality of holes 25a formed in the side wall of the rotating body 25. In addition, the water droplets that fly out of the rotating body 25 collide with the inner wall surface of the cylindrical body 20 and are further miniaturized. For this reason, fine dust and bacteria contained in the air introduced from the room can be efficiently captured, and the air cleaning function can be enhanced.

Moreover, since the gas-liquid contact part Da is configured the same as the pre-wash part Ab, the water can be efficiently made fine by the high speed rotation of the rotating body 35. Therefore, fine dust and the like that could not be removed by the pre-cleaning section Ab can be removed, and the air can be reliably purified.

In addition, since the rotating bodies 25 and 35 rotate at a high speed, the energy given to the water droplets increases, and the water droplets fly out of the rotating bodies 25 and 35 to form the cylindrical body 2.
The energy at the time of colliding with the inner wall surface of 0, 30 is inevitably increased. Therefore, at the time of collision, a large amount of negative ions are generated, and as a result of adding both negative ions, the amount of negative ions discharged into the room from the droplet separation section E increases, and natural ions in the vicinity of forests and waterfalls are increased. A state close to the environment can be realized, and a more refreshing feeling of mind and body can be obtained.

In particular, the rotating bodies 25 and 35 may be provided in only one stage as shown in the figure, but if they are arranged in a plurality of stages, water droplets can be efficiently miniaturized and the air cleaning function can be enhanced. It is possible to increase the generation amount of negative ions. In addition, the nozzle 22 is inevitably formed in a plurality of stages by forming the rotating body into a plurality of stages.

FIG. 6 shows a fourth embodiment of the mist generator according to the present invention. The basic configuration is the same as that of the embodiment shown in FIG. The different point is that the arrangement structure of the motors 26 and 36 in the pre-washing part Ab and the gas-liquid contact part Da is changed. Since both have the same structure, only the configuration of the pre-washing section Ab will be described. In the pre-washing section Ab, the motor 26 is fixed to the top Qa of the concave portion Q formed so as to increase the bottom of the first water tank B.
In particular, the height of the concave portion Q is set to be higher than the water surface of the first water tank portion B, and the shaft 2 extending from the motor 26
Reference numeral 7 is configured so as not to be constantly immersed in the water of the first water tank section B.

According to this embodiment, the same effects as in the third embodiment can be obtained. In addition, the rotating shaft 27 (37)
Is not always immersed in the water of the water tank section B, the watertight structure at the top Qa can be simplified, and assembly can be performed easily.

FIG. 7 shows a fifth embodiment of the mist generator according to the present invention. The basic configuration is the same as that of the embodiment shown in FIG. The difference is that a rotating disk method is employed for the water miniaturization means in the prewash section Ac and the gas-liquid contact section Db.

For example, a cylindrical body 30 and a plurality of nozzles 32 radially arranged obliquely downward on an upper portion of the inner wall surface of the cylindrical body 30
A pipe 31 having an end connected to a nozzle 32, a nozzle 32 disposed at a lower end of the pipe 31, and water in a second water tank portion F. A second pump 33 for pressure-feeding to the nozzle 32, a rotary plate 35 </ b> A arranged so that water discharged from the nozzle 32 hits the center of the cylindrical body 30, and a second pump 33 fixed to the top of the cylindrical body 30. And a motor 36 for imparting rotation to the rotating plate 35A via a rotating shaft 37.

The mist generator operates as follows. Note that the droplet separation unit E is the same as in each of the above-described embodiments, and a description thereof will be omitted. First, in a state where the indoor air is being introduced into the tubular body 20 of the pre-washing section Ac by the fan 1, the rotation of the motor 26 is controlled by the rotating plate 2 via the rotating shaft 27.
When transmitted to 5A, the rotating plate 25A rotates in a specific direction at a predetermined speed. At this time, the water pumped by the pump 23 is supplied from the nozzle 22 through the pipe 21 to the rotating plate 2.
It is injected toward 5A. The injected water is a rotating plate 25A.
In addition, the particles are scattered and collide with the inner wall surface of the cylindrical body 20, and are further miniaturized. At this time, a large amount of negative ions are generated. When the micronized water droplets come into contact with air introduced from the room, they take in bacteria, fine dust, smoke of tobacco, and the like contained in the air, and swirl inside the cylindrical body 20 to descend. During this downward movement, water droplets whose diameter has been increased from the beginning due to the incorporation of fine dust or the like cannot be swirled due to the swirling force applied to the mixture of air and water droplets, or fall, or It collides with the inner wall surface and flows down to the first water tank B to be collected.

An air-fuel mixture containing air which has been preliminarily cleaned in the pre-washing section Ac is introduced through the connecting pipe 24 along the inner peripheral surface of the cylindrical body 30 in the gas-liquid contact section Db. It rises while turning along its inner wall. At the same time, the water stored in the second water tank F is
, And is jetted from the nozzle 32 toward the rotary plate 35A. The injected water is a rotating plate 35
In addition to being scattered by colliding with A, it collides with the inner wall surface of the cylindrical body 30 to be further miniaturized, and at this time, a large amount of negative ions are generated. Then, the liquid is brought into contact with and mixed with the circling air, rises while circling, and is sent out to the droplet separation unit E via the connecting pipe 34. It should be noted that negative ions generated in the process of generating fine water droplets due to the rotation of the rotating plate 35A are generated in the pre-cleaning section A
It is added to the negative ions generated in c. In addition, due to the contact between the air and the fine water droplets, many fine dusts and the like that could not be removed in the pre-washing section Ac are again attached to the water droplets. As a result, the diameter of the water droplets adhering to the dust is increased from the beginning, so that the water droplets cannot be swirled by the swirling force applied to the air-fuel mixture and fall, or collide with the inner wall surface of the cylindrical body 30, resulting in the second water droplets. It flows down to the water tank section F and is collected.

According to this embodiment, since the rotating plate 25A is rotated at a high speed in the pre-washing section Ac, the water droplets scattered by colliding with the rotating plate 25A further collide with the inner wall surface of the cylindrical body 30. Is further miniaturized. For this reason, fine dust and bacteria contained in the air introduced from the room can be efficiently captured, and the air cleaning function can be enhanced.

Further, since the gas-liquid contact portion Db is configured in the same manner as the pre-wash portion Ac, water can be efficiently made fine by the high-speed rotation of the rotating plate 35A. Therefore,
Fine dust and the like that could not be removed by the pre-washing section Ac can be removed, and the air can be reliably cleaned.

In addition, since the rotating plates 25A and 35A rotate at a high speed, the energy given to the water droplets increases, and the energy when colliding with the inner wall surfaces of the cylindrical bodies 20 and 30 is inevitable. Become larger. Therefore, in the event of a collision,
A large amount of negative ions are generated, and both negative ions are added. As a result, the amount of negative ions discharged into the room from the droplet separation unit E increases, and a state close to the natural environment near a forest or waterfall can be realized. And a more refreshing feeling of mind and body can be obtained.

In particular, the rotating plates 25A and 35A may be provided in only one stage, but if they are arranged in a plurality of stages, the water droplets can be efficiently miniaturized, the air cleaning function can be enhanced, and negative ions can be improved. Can be increased.

The present invention is not limited to the above embodiment. For example, the means for miniaturizing water includes all means for miniaturizing water by any means. For example, a rotating body of a water wheel type is arranged so as to be in contact with the water surface of the water tank portion, and water is scraped up by the rotation of the rotating body to make it fine, or two rotating disks are arranged parallel to the water surface. Alternatively, a structure in which water is scattered by using a negative pressure generated between rotating disks rotating at high speed may be employed. In the above embodiment, most of the main parts of the pre-washing part and the gas-liquid contact part have the same configuration. However, the pre-washing part of the first embodiment has the same structure as the third to fifth embodiments. The pre-washing unit shown in the drawings is applied, the gas-liquid contacting unit shown in the third to fifth embodiments is applied to the gas-liquid contacting unit of the first embodiment, or the respective pre-washing unit and gas-liquid contacting unit are used. It can also be suitably combined and constituted. Also, the first and second water supply tanks can be integrated into one and supplied separately to the first and second water tanks. It is desirable that the rotating direction of the rotating body, the rotating plate, and the like match the direction of the air introduced by the fan, but it is also possible to set the rotating direction to the opposite direction. Further, the filter may be omitted depending on the space to be purified. Further, the function of the liquid drop separating section can be included in the gas liquid contact section by omitting the liquid drop separating section or integrating the gas-liquid contacting section and the liquid drop separating section.

[0053]

As described above, according to the present invention, before the air introduced from the space to be purified is introduced into the gas-liquid contact section, bacteria, fine dust and the like contained in the introduced air in the pre-wash section are removed. Because of the preliminary cleaning and removal, the amount of bacteria, fine dust, and the like contained in the air-fuel mixture introduced into the gas-liquid contact portion can be significantly reduced. Therefore, the purified air-fuel mixture can be discharged from the gas-liquid contact part, preferably the droplet separation part, into the space to be purified, and a high-quality cleaning function can be exhibited.

In the pre-washing section and the gas-liquid contacting section, the first water tank section and the second
Since the water in the water tank part is separately used, the contamination of the water in the second water tank part due to the air-fuel mixture introduced from the pre-wash part to the gas-liquid contact part can be remarkably reduced, and the water is cleaned for a long time. The air-fuel mixture thus generated can be generated and can be continuously sent to the droplet separation unit.

Further, since the water in the first water tank associated with the pre-washing section has a rapid progress of contamination, it is necessary to change the water at an early stage. However, the structure in the first water tank and the pre-washing section is difficult. Since the structure is simpler than the structure of the gas-liquid contact part including the second water tank part and the structure of the liquid drop separation part, the exchange of water can be performed relatively easily, and the maintainability is improved as compared with the conventional apparatus. Can be improved.

In particular, if an ultraviolet ray generating device or a photocatalyst device is arranged in the first water tank portion, and preferably also in the second water tank portion, propagation of bacteria, molds and the like can be suppressed, and deterioration of water quality,
The progress of contamination can be suppressed, and the frequency of water exchange can be reduced.

Furthermore, if the pre-washing section is provided with a function of generating negative ions, negative ions are generated in both the pre-washing section and the gas-liquid contact section. Is added. Therefore, the amount of negative ions discharged into the space to be purified can be significantly increased as compared with the case where only the gas-liquid contact portion is used, and a state close to a natural environment near a forest or a waterfall can be realized. It gives a refreshing feeling of mind and body.
