BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an air cleaner capable of deodorizing indoor air or deodorizing deposits such as indoor walls, and more particularly, to an air cleaner using the technique of electrostatic atomization.

Many conventional air cleaners are provided with a filter such as a filter for trapping dust and dirt in the air, and a filter such as activated carbon for adsorbing odor molecules. Further, deodorization is also provided using a technique of electrostatic atomization, such as Patent Document 1 (Japanese Patent Laid-Open No. 53-141167) and Patent Document 2 (Japanese Patent Laid-Open No. 2001-286546). Here, the electrostatic atomization refers to a phenomenon in which water is misted when a high voltage is applied to a liquid such as water and the liquid is exposed during electrolysis.

Disclosed in the patent document 1 is to cause the air sucked into the air cleaner to contact the mist generated in the electrostatic atomization unit to trap the contaminated mist in the gas-liquid contact portion, and also in the patent document 2 Disclosed is to atomize the liquid deodorant in the electrostatic atomization unit to generate mist and spray in the air.

In the prior art disclosed in Patent Document 1, since contaminated air always comes in contact with the electrostatic atomization part, dust or dust sticks to the electrostatic atomization part, and there is a concern that electrostatic atomization is unlikely to occur even when a high voltage is applied. . For this reason, it was necessary to frequently clean the electrostatic atomization part. In addition, in the above-mentioned conventional example, only the air sucked into the air cleaner is used to purify, and deposits such as the interior wall surface cannot be deodorized.

On the other hand, in the conventional example disclosed in Patent Document 2, only the electrostatic atomization unit is described as being incorporated into the air purifier, and it is not disclosed where it is specifically arranged, and also described as spraying mist generated in the electrostatic atomization unit. However, in combination with an air cleaner, there is no description on how to diffuse into the air, and it has not been put to practical use at present.

SUMMARY OF THE INVENTION The present invention has been made in view of this point, and an object of the present invention is to provide an air cleaner that can efficiently diffuse generated mist into a room and effectively deodorize deposits such as indoor air and an interior wall surface.

In order to solve the above problems, the air purifier according to the present invention, the air purifier having a blower (4) for purifying the air sucked from the suction port (1) in the filter 2 and discharged from the discharge port (3) In (A), the water holding part 5, the conveying part 6 which conveys the water of the said water holding part 5 toward the front end located in the water holding part 5 outside, and the conveying part 6 ) And a voltage application section 8 for applying a high voltage between the transport section 6 and the electrode 7, and the transport section 6 and the electrode ( By applying a high voltage between 7), an electrostatic atomization 9 for atomizing water in the transfer section 6 and generating mist is provided, and the transfer section 6 and It is characterized in that the electrode 7 is provided on the downstream side of the filter 2.

By such a configuration, the mist generated by atomizing the water in the conveying unit 6 by applying a high voltage between the conveying unit 6 and the electrode 7 together with the air purified by the filter 2 It spreads in the atmosphere outside the purifier A, and it is possible to effectively perform deodorization in indoor air, deodorization with respect to deposits, such as an interior wall surface.

Moreover, it is preferable to provide the conveyance part 6 and the electrode 7 in the air path 10 from the suction port 1 to the discharge port 3.

By this structure, electrostatic atomization is performed in the air passage 10 through which the purified air flows, and the amount of atomization increases, and the conveyance part 6 and the electrode 7 in the air passage 10 are carried out. ), The conveying part 6 and the electrode 7 are exposed to the air purified by the filter 2, so that no dust or dirt adheres to the conveying part 6 and the electrode 7. As a result, it is possible to eliminate such a phenomenon that electrostatic atomization is less likely to occur even when a high voltage is applied due to the adhesion of dust and dirt.

In addition, the conveyance part 6 and the electrode 7 are provided outside the discharge port 3, and at the same time, the generated mist can be attracted by the air flow discharged from the discharge port 3. It is preferable to provide the conveyance part 6 and the electrode 7.

With such a configuration, a mist generating section for generating a mist by atomizing water in the conveying section 6 by applying a high voltage between the conveying section 6 and the electrode 7 is applied to the air flow discharged from the ejection opening 3. Since it is not directly exposed, and thus is not directly affected by the air flow discharged from the discharge port 3, generation of fine mist by electrostatic atomization at an external position of the discharge port 3 can be carried out efficiently and accurately. 3) The mist generated efficiently and accurately without being affected by the air flow discharged from 3) is attracted by the air flow discharged from the discharge port 3 and diffused into the atmosphere outside the air cleaner A together with the air purified by the filter 2. It is possible to let.

Furthermore, the conveyance part 6 and the electrode 7 are provided outside the air path 10 from the inlet 1 to the discharge port 3, and the generated mist is caused by the air flow flowing through the air path 10. It is preferable to provide the conveyance section 6 and the electrode 7 in a position where it can be attracted.

With such a configuration, a mist generating section for generating a mist by atomizing water in the conveying section 6 by applying a high voltage between the conveying section 6 and the electrode 7 from the suction port 1 to the discharge port 3. Generation of fine mist by electrostatic atomization at an outside position of the air path 10 without directly being exposed to the air flow flowing through the air path 10 leading to the air flow flowing in the air path 10. Can be performed efficiently and accurately, and in this way, the mist generated efficiently and accurately without being influenced by the air flow flowing in the air path 10 is attracted into the air path 10 by the air flow flowing in the air path 10 to filter It is possible to diffuse into the atmosphere outside the air cleaner A together with the air purified in (2).

[Examples of the Invention]

EMBODIMENT OF THE INVENTION Hereinafter, this invention is demonstrated based on the Example shown to an accompanying drawing.

1 and 2 show an example of the air cleaner A of the present invention. The air cleaner A includes the air cleaner 12 and the electrostatic atomizer 9 in the main body case 11.

The air cleaner 12 has a suction port 1 for suctioning indoor air, a discharge port 3 for discharging filtered air into the room, and a suction port 1 from the suction port 1, similarly to a conventional air cleaner. A filter (2), such as a nonwoven fabric or activated carbon, installed in the air passage (10) leading to the air blower (4) provided with a fan (4a), and sucks indoor air from the inlet port (1) into the air cleaner (12). And cleans the air by filtration by the filter 2, and discharges the purified air from the discharge port 3 back to the room, and is indoors by the so-called filtration method (filtering method). It is designed to remove the smell of floating in the air.

Although the electrostatic atomizer 9 is provided in the main body case 11 in addition to the air cleaner 12 as described above, the electrostatic atomizer 9 is water (W) as shown in the principle diagram shown in FIG. It arrange | positions so that it may face the conveyance direction of the water pooling part 5 which is injected, the conveying part 6 which conveys water W from the water pooling part 5, and the water W by the conveying part 6. And a voltage applying section 8 for applying a high voltage between the conveyed electrode 7 and the conveyance section 6 and the electrode 7.

Here, in the air cleaner A of this invention, the conveyance part 6 and the electrode 7 of the electrostatic atomizer 9 are provided in the downstream of the filter 2 at least. By applying a high voltage between the transfer section 6 and the electrode 7, water W at the tip of the transfer section 6 is charged and atomized to generate a mist size M in nano size. And since the conveyance part 6 and the electrode 7 are provided downstream of the filter 2 in this invention, as mentioned above, the nano size which generate | occur | produced by applying a high voltage to the conveyance part 6 and the electrode 7 is mentioned. The mist M diffuses into the atmosphere outside the air cleaner A together with the air purified by the filter 2, and can effectively deodorize the indoor air or deodorize deposits such as the interior wall surface. In addition, when contaminated with contaminated air in the atmosphere, the contaminated air and mist immediately come into contact with each other, so that the ratio of mist containing odor molecules and the like is increased, and the deodorizing effect on the adherents such as indoor air and the interior wall surface is increased. In the present invention, since the nano-sized mist M is diffused into the atmosphere together with the air purified by the filter 2 as described above, the deodorizing effect on the adherents such as indoor air and the interior wall surface is reduced. There is no deterioration.

3 to 5 show an example of the electrostatic atomizer 9 provided in the air cleaner of the present invention. The electrostatic atomizer 9 has a water tank 5a constituting the water pool 5 at the bottom thereof, and is a holder 14 having a cylindrical shape and a ventilation hole 13 opening in a main surface thereof. And the electrode 7 disposed on the upper part of the holder 14 (hereinafter referred to as the opposite electrode 7 because it is the opposite electrode) and the lower part of the holder 14, An application electrode 15 which is responsible for voltage application, a plurality of rod-shaped absorbers 6a constituting the transfer section 6 supported by the application electrode 15, and also an application electrode 15 The water tank 5a, which is composed of an ionization needle 16 supported by a cup, and is formed in a cup shape, has projections 35 on the outer surface of the upper opening edge of the lower portion of the holder 14. It is attached by engaging the bayonet to the engaging recess 18 formed in the outer circumferential flange 17 of the application electrode 15 mounted on the The.

The counter electrode 7 and the applied electrode 15 are formed of a metal such as stainless resin (SUS) or a synthetic resin mixed with a conductive material such as carbon, and are electrically conductive. Therefore, the counter electrode 7 and the applied electrode 15 are covered with an upper portion of the holder 14. The electrode 7 is grounded through the ground contact plate 20 in contact with the outer surface of the connecting projection 19 formed on the outer circumferential surface thereof. The contact electrode 15, which is inserted into the lower part of the holder 14 and fixed and is pressed and fixed to the rib 21 on the inner surface of the holder 14, also contacts the outer surface of the connecting projection 26 formed on the outer circumferential surface thereof. It is connected to the voltage application part 8 which applies a high voltage via the 22.

The rod-shaped absorbent body 6a is formed of, for example, a porous ceramic, and its upper end is pointed in the shape of a needle, and a plurality of, in the illustrated example, six absorbers 6a are attached to the application electrode 15. These absorbers 6a are arranged at equal intervals on the same circle centering on the ionization needle 16 disposed in the center of the application electrode 15, the upper portion protruding upwards from the application electrode 15, and the lower portion It protrudes downward and contacts water W injected into the water tank 5a.

In the figure, reference numeral 23 denotes a cylindrical skirt which protrudes downward from the application electrode 15, and surrounds the outer side of the plurality of absorbers 6a, and the lower end thereof is lower than the lower end of the absorber 6a. In the bottom opening, a lattice-shaped lattice protective cover 24 is covered. The skirt 23 of the applying electrode 15 applies a high voltage to the water W by contacting the water W injected into the water tank 5a and at the same time, the lattice protective cover 24. And to protect the absorber 6a formed of ceramic together.

Here, since the application electrode 15 almost closes the opening of the upper surface of the water tank 5a when the water tank 5a is connected, the water W in the water tank 5a leaks even when it is inclined. In this relationship, the slit 29 is formed in a part of the circumferential direction of the skirt 23 over the entire length of the skirt 23, and when the water tank 5a into which the water W is injected is mounted. The air in the space surrounded by the skirt 23 by the slit 29 is extracted to allow the water W to flow into the skirt 23.

The counter electrode 7 mounted to close the upper opening of the holder 14 has an opening 25 at the center as shown in Fig. 4, and the edge of the opening 25 is viewed from above. Further, a plurality of circular arcs R having the same diameter centering on the needle-shaped portions at the upper ends of the plurality of absorbers 6a are smoothly connected to the other arcs r. When the counter electrode 7 is grounded and a high voltage source is connected to the application electrode 15, and the absorber 6a sucks up water W by capillary action, the needle-shaped portion of the upper end of the absorber 6a is applied to the electrode. The rod-shaped absorbent body constituting the conveying section 6 which functions as a substantial electrode on the side of 15 and the circular arc R of the counter electrode 7 functions as a substantial electrode and conveys water W ( A high voltage is applied between the tip of 6a) and the counter electrode 7. The opening 25 is covered with a lattice protective cover 39 to prevent a finger or the like from coming into contact with the ionization needle 16 and the absorber 6a through the opening 25.

Now, the water tank 5a in which the water W is put is mounted, the water W is brought into contact with the skirt 23 of the application electrode 15, and the water W is caused by capillary action to the absorber 6a. And the negative electrode 7 are grounded, a high voltage source is connected to the applying electrode 15, and a negative voltage is applied to the applying electrode 15. A high voltage is applied between the tip of the shape absorber 6a and the counter electrode 7. If this voltage is a high voltage capable of causing Rayri breakup in the water W, the water W reaching the needle-shaped portion of the upper end of the absorber 6a causes the Rayri breakup here, which causes mist of nanometer size particle diameter. The electrostatic atomization which produces atomization which becomes (M) is made.

In this electrostatic atomizer 9, a high negative voltage is simultaneously applied to the ionization needle 16, and negative ions are also generated by corona discharge between the counter electrodes. At this time, if the distance between the electrodes is the same, the voltage required for electrostatic atomization is higher than the voltage necessary for generating negative ions, and therefore, the distance L1 from the needle-shaped portion at the upper end of the absorber 6a to the counter electrode 7 here. Furthermore, the electrostatic atomization is more likely to occur by significantly lengthening the distance L2 from the ionization needle 16 to the counter electrode 7. However, if the water W in the water tank 5a disappears and the water W held in the absorber 6a is also not atomized, only the generation of the anion is continued.

In the present invention, as described above, the conveying section 6 and the electrode 7 of the electrostatic atomizing device 9 are provided downstream of the filter 2. In the embodiment shown in Figs. The electrostatic atomization apparatus 9 provided with the conveyance part 6 and the electrode 7 of the above structure is provided in the air path 10 from the inlet port 1 to the discharge port 3. That is, the blowing unit 4 is composed of a fan 4a and a wind tunnel 4c driven by the motor 4b, and filters the indoor air sucked from the blowing unit 4 by driving the fan 4a. After filtration by (2), the purified air is discharged from the discharge port 3 back to the room. Among the air paths 10 of the air cleaner A, the wind tunnel at the blower 4 The electrostatic atomizer 9 is provided in 4c) and near the discharge port.

Nano-size mist, a nanometer-sized particle diameter mist produced by electrostatic atomization, has a high diffusivity, but it is more diffused because purified air spreads through an air stream blown by a blower, and also purified air Since the nano-sized mist does not come into direct contact with the polluted air because it spreads through the flow of air, it spreads through the purified air to the far side. It is possible to effectively deodorize a wide range by effectively utilizing the deodorizing function for the attachments of. In particular, in the embodiment shown in Figs. 1 and 2, when the electrostatic atomizer 9 is disposed in the storage recess 27 provided in a part of the wind tunnel 4c, the contact plates 20 and 22 are used for the connection. Through the openings 28 opened in the wall of the receiving recess 27 and the ventilation holes 13 in the holder 14 of the electrostatic atomizer 9 to enable contact with the projections 19 and 26, a blackout Since a part of the wind flows into the atomizer 9, the atomization is promoted, the atomization amount is increased, and the mist M is easily blown off by the wind.

Moreover, although the electrostatic atomizer 9 is arrange | positioned in the wind tunnel 4c, the air which passes through the electrostatic atomizer 9 is clean air filtered by the filter 2, for this reason, the electrostatic atomizer 9 Since it is not contaminated, some wind flows into the electrostatic atomizer 9 as described above, but it is rarely difficult for electrostatic atomization to occur due to contamination.

7 and 8 show yet another embodiment of the present invention. In the embodiment shown in Figs. 1 and 2, when the conveyance section 6 and the electrode 7 of the electrostatic atomizer 9 are provided downstream of the filter 2, the discharge port (from the inlet port 1) Although the conveyance part 6 and the electrode 7 were installed in the air path 10 which reached 3), as shown in FIG.7, FIG.8, the conveyance part 6 and the electrode (which become a mist generating part) are shown. 7) is also generated in a position where the air flow blown by the blower 4 is not in direct contact (i.e., a position not directly exposed to the air flow blown by the blower 4). It may be provided at a position attracted to the air flow blown by the blower (4).

In the embodiment shown in Fig. 7, the transfer section 6 and the electrode 7 are provided outside the discharge port 3, and the generated mist M is attracted by the air flow discharged from the discharge port 3. The example which provided the said conveyance part 6 and the electrode 7 in the possible position is shown. That is, in the present embodiment, the electrostatic atomizer 9 is accommodated and installed in the storage recess 27 provided outside the air passage 10 in the main body case 11. The opening part of the accommodating recessed part 27 used as the exit 42 to the outside of the mist M in the state accommodated in the part 27 is open | released outside the discharge port 3, and is located. The nano-sized mist M generated by applying a high voltage between the transfer section 6 and the electrode 7 is discharged from the outlet 42 by the air flow discharged from the discharge port 3. Outwardly, it diffuses with the air purged from the discharge port 3 into the atmosphere outside the air cleaner A, and can deodorize indoor air and deodorize deposits, such as an interior wall surface effectively. In this embodiment, the mist generating part which applies high voltage between the conveyance part 6 and the electrode 7, and atomizes the water of the conveyance part 6, and generate | occur | produces the mist M is discharged from the discharge port 3 There is no direct exposure to the air stream. Therefore, electrostatic atomization can be performed at an external position of the discharge port 3 without being directly affected by the air flow discharged from the discharge port 3, and it is possible to efficiently and accurately generate fine nano-size mist M by the electrostatic atomization. It can be.

In addition, in the embodiment shown in FIG. 8, while the conveyance part 6 and the electrode 7 are provided in the outer side of the air path 10 from the suction port 1 to the discharge port 3, the mist which generate | occur | produced the said The conveying unit 6 and the electrode 7 are installed at positions that can be attracted to the middle of the air path 10 by the air flow flowing through the air path 10.

That is, in FIG. 8, in the main body case 11, the electrostatic atomizer 9 is disposed outside the air passage 1, and the electrostatic atomizer 9 is formed in the middle of the wind tunnel 4c constituting a part of the air passage 10. As shown in FIG. The outlet 42 of the nano-size mist M generated in the above is communicated with each other. Therefore, the nano-size mist M generated by applying a high voltage between the conveying part 6 and the electrode 7 of the electrostatic atomizer A disposed outside the air passage 10 is an air flow flowing through the air passage 10. Enters into the air passage 10 from the outlet 42 in communication with the middle of the air passage 10, and discharges the air from the discharge port 3 into the atmosphere outside the air cleaner A together with the purified air flowing through the air passage 10. Since it diffuses together with the purified air, deodorization in indoor air and deodorization of deposits, such as an interior wall surface, can be performed effectively. In this embodiment, the mist generating portion which applies a high voltage between the conveyance part 6 and the electrode 7 to atomize the water of the conveyance part 6, and generate | occur | produces the mist M, discharges from the inlet 1 It is not directly exposed to the air stream flowing through the air path 10 up to (3). Therefore, it is possible to efficiently and accurately generate fine nano-size mist M by electrostatic atomization at an external position of the air passage 10 without being directly affected by the air flow flowing in the air passage 10.

 On the other hand, the air cleaner A of the present invention may operate the air cleaner 12 and the electrostatic atomizer 9 at the same time, stops the operation of the electrostatic atomizer 9 and operates only the air cleaner 12. Alternatively, the operation of the air cleaner 12 may be stopped and only the electrostatic atomizer 9 may be operated. The operation mode may be arbitrarily selected.

By the way, in the said Example, although the carrying part 6 which has water absorptivity which conveys water was demonstrated to the example formed with the porous ceramic, the conveying part 6 which conveys water from the water holding part 5 is formed by felt, Also good. Thus, when the conveyance part 6 is formed by felt, the conveyance part 6 can be formed in low cost, and the nano-size mist M containing an active species can be atomized at low cost, and can be sent indoors, The smell attached to the wall can be removed. And when the conveyance part 6 is comprised by felt, the tip part which opposes the felt electrode 7 will be pointed. Thus, the tip of the felt facing the electrode 7 is pointed. In this way, when a high voltage is applied between the transfer section 6 and the electrode 7 by the voltage applying section 8, the electric field is concentrated on the sharp part of the tip of the felt, and a large amount of active species is efficiently carried out. It is possible to atomize the nano-size mist (M) containing, and in this way can efficiently atomize the nano-size mist (M) containing a large amount of active species and send it to the room, so the odor attached to the indoor wall, etc. Can be removed.

As mentioned above, in forming the conveyance part 6 by felt, it is preferable to use the thing with weak hydrophilicity as a felt to use. When a weak hydrophilic felt is used, a high voltage is applied between the transfer section 6 and the electrode 7 by the voltage applying section 8, and water at the tip of the transfer section 6 can be atomized by the high voltage. At this time, the water (W) is likely to fall from the felt, so that the nano-size mist (M) containing a large amount of active species can be atomized efficiently, and the odor attached to the interior wall can be efficiently removed by sending this to the room. It can be.

In addition, in forming the conveyance part 6 by the felt, the felt used may be the thing which carried out desurfactant treatment. Also in this case, when the high voltage is applied between the conveyance part 6 and the electrode 7 by the voltage application part 8, and the water W at the tip of the conveyance part 6 is atomized by the high voltage, Water (W) tends to fall from the felt, so that the nano-size mist (M) containing a large amount of active species can be atomized efficiently and sent to the room to efficiently remove the odor attached to the interior wall or the like. You can do it.

Moreover, it is preferable to use the thing with high porosity as a felt to use. For example, the porosity of about 75% is preferable because the conveyance amount of water (W) increases, but, for example, the porosity of about 50% or less is not so preferable because of the small amount of water conveyance. When the felt having high porosity is used as described above, the amount of transport of water increases, so that the nano-size mist (M) containing a large amount of active species can be efficiently atomized, and it is attached to the interior wall or the like by sending it to the room. The smell can be removed efficiently.

In addition, it is preferable to use a felt or a thing with a large fiber diameter as a felt to be used. For example, a fiber diameter of about 20 d is preferable because the amount of conveyance of water W increases, but, for example, a fiber diameter of about 3 d or less is not preferable because the amount of conveyance of water W decreases. As described above, when the felt or the fiber having a large diameter is used, the amount of transport of water (W) increases, so that the nano-sized mist (M) containing a large amount of active species can be efficiently atomized. By sending it out, the odor attached to the interior wall or the like can be efficiently removed.

In this embodiment, the transport amount of the water W is increased, so that the nano-size mist M containing a large amount of active species can be atomized efficiently, and the odor adhered to the interior wall or the like by sending this to the room. Can be removed efficiently. In addition, since negative ions can be generated effectively at the same time, it can be supplied to the room.

In each of the above-described embodiments, the discharge port 3 is provided on the upper surface of the main body case 11 of the air cleaner A, and generated in the electrostatic atomizer 9 together with the air purified by the filter 2. Although the nano-size mist M is sent out indoors, the discharge port 3 may be provided in the front surface of the main body case 11 of the air cleaner A. As shown in FIG. As a result, the discharging direction of the atomized mist M becomes the front direction of the air purifier A. The nano-sized mist M containing the active species is efficiently diffused and discharged into the room to be attached to the interior wall surface or the like. Odor can be removed efficiently.

As described above, in the present invention, by applying a high voltage between the conveying part and the electrode, mist generated by atomization of water in the conveying part is diffused into the atmosphere outside the air cleaner A together with the air purified by the filter. This can effectively deodorize indoor air or deodorize attached objects such as indoor walls.
