JP4886974B2 - AIR CLEANING UNIT AND AIR CONDITIONER HAVING THE SAME - Google Patents

Description

  The present invention relates to an air cleaning unit including an air filter and an air conditioner including the air cleaning unit.

  In recent years, air purifiers that remove odors, dust, bacteria, viruses, and the like floating in the air have become widespread.

  Some of these air purifiers use ozone to decompose, kill, or inactivate odor molecules, dust, bacteria, viruses, and the like. Usually, ozone is generated by an ozone generator and decomposes, kills, or inactivates odor molecules, bacteria, viruses, and the like existing in the vicinity. For this reason, not only indoor air but also the inside of the air purifier is kept clean, and the risk of secondary infection and the like can be reduced.

For example, Patent Literature 1 discloses an air purifier including a prefilter, a plasma ionization unit, an electrostatic filter, a titanium oxide filter, a photocatalytic filter, an inverter lamp, and the like as filters. According to this air cleaner, after relatively large dust or dust is collected by the prefilter, the smoke or dust charged through the plasma ionization unit is adsorbed by the electrostatic filter. Then, the photocatalyst filter is irradiated with ultraviolet rays from the inverter lamp to activate the photocatalyst, and the air passing through the photocatalyst filter can be purified by the photocatalytic action.
JP 2004-60947 A (published February 26, 2004)

  However, the conventional air cleaner has the following problems.

  That is, the air cleaner disclosed in the above publication requires an inverter lamp (light source) for activating the photocatalyst carried on the photocatalyst filter, and there is a problem that the configuration becomes complicated. Furthermore, in order to uniformly irradiate the photocatalyst with ultraviolet light from the inverter lamp, a flat filter must be used as a filter carrying the photocatalyst. For this reason, it has been difficult to employ a pleated filter with high collection efficiency and low pressure loss.

  An object of the present invention is to provide an air purification unit capable of simplifying the configuration and effectively activating a photocatalyst carried on a filter even when a pleated filter is used, and an air conditioner including the same Is to provide.

  The air conditioner according to the first invention includes a pleated air filter and an active species generator. The pleated air filter adsorbs at least one of dust, odor molecules, viruses and fungi floating in the air. The active species generating unit generates active species that decompose, kill, or inactivate at least one of dust and the like.

  Here, a pleated air filter and an active species generator are provided, and dust or the like collected by the air filter is decomposed, killed, or inactivated by the active species generated in the active species generator.

  As a result, by using a pleated air filter, the dust collection area can be expanded and dust can be adsorbed efficiently compared to the case of using a flat air filter, and the pressure loss is reduced and the life of the filter is reduced. A long air filter can be obtained.

Moreover, in the air purifying unit of the first invention, the air filter carries a predetermined catalyst that is a photocatalyst that decomposes, kills, or inactivates at least one of dust and the like, and that is also activated by active species. Yes.

Here, a pleated air filter and an active species generator are provided, and a predetermined catalyst carried on the air filter is activated by the active species generated in the active species generator.

  Furthermore, in the air conditioner according to the first invention, a streamer discharger is employed as the active species generator.

  In general, a streamer discharger can generate a stronger discharge field than a glow discharger, a barrier discharger, or the like, and therefore can generate active species at a higher energy level than other plasma generators. Therefore, it becomes possible to further increase the rate of decomposing, killing, or inactivating odor molecules, bacteria, viruses, and the like.

The streamer discharge is formed as a plasma column accompanied by light emission by continuous micro arc from the tip of the discharge end to the counter electrode. Then, when this streamer discharge is performed, low temperature plasma is generated in the discharge space, and the active species (factors acting on components to be treated such as odorous substances and harmful substances contained in the air to be treated) by this low temperature plasma , Radicals such as ions , ozone, and hydroxy radicals, and other excited molecules (excited oxygen molecules, excited nitrogen molecules, excited water molecules, etc.) are generated.

  Furthermore, the air conditioner according to the first aspect of the present invention includes an air blowing unit that forms an air flow from the active species generating unit side to the air filter side of the air cleaning unit.

Here, a predetermined catalyst carried on the air filter is activated by the active species by sending the active species to the pleated air filter by the air blowing unit that forms the air flow from the active species generating unit to the air filter. Make it.

  Usually, an air filter such as a filter carrying a photocatalyst as described above requires a light source for irradiating light to activate the photocatalyst. When a pleated air filter is used, a portion where light from the light source does not reach sufficiently is formed, so that it is necessary to use a flat one.

Therefore, according to the air conditioner of the present invention, since the predetermined catalyst of the air filter can be activated using the active species generated in the active species generating unit, a light source can be made unnecessary. Since a pleated air filter can be used, the dust collection area can be expanded and dust and the like can be efficiently adsorbed and pressure loss can be reduced compared to the case of using a flat air filter. A long-life air filter can be obtained.
An air conditioner according to a second invention is the air conditioner according to the first invention, and the air filter has apatite.

  Here, since the air filter has apatite, odor molecules, bacteria, viruses, and the like can be strongly adsorbed. Therefore, the efficiency of decomposing, killing, or inactivating odor molecules, bacteria, and viruses can be increased.

The apatite is a chemical formula Ax (BOy) zXa (A is various metal atoms such as Ca, Co, Ni, Cu, Al, La, Cr, Fe, and Mg, and B is an atom such as P and S. , X is a substance represented by a hydroxyl group (—OH) or a halogen atom (for example, F, Cl, etc.), and representative examples thereof are hydroxyapatite, fluoroapatite, chloroapatite, and triphosphate. Calcium and calcium hydrogen phosphate. Among these, calcium hydroxyapatite represented by Ca ₁₀ (PO ₄ ) ₆ (OH) ₂ is highly adsorbable because it easily exchanges ions with both cations and anions, and is particularly excellent in the ability to adsorb organic substances such as proteins. ing. In addition, it is known that calcium hydroxyapatite can inhibit or suppress their growth by strongly adsorbing fungi and bacteria.

  An air conditioner according to a third invention is the air conditioner according to the second invention, and the apatite has a photocatalytic function.

  Here, since apatite has a photocatalytic function in which its photocatalytic function is activated not only by ultraviolet rays but also by active species, not only active species but also active species such as hydroxy radicals generated by a photocatalytic reaction have an odor. It can contribute to the degradation, death, or inactivation of molecules, fungi, and viruses. Therefore, the efficiency of decomposing, killing, or inactivating odor molecules, bacteria, and viruses can be further increased.

  The apatite having the photocatalytic function refers to, for example, apatite in which some calcium atoms of calcium hydroxyapatite are substituted with titanium atoms by a technique such as ion exchange. The apatite having a photocatalytic function is, for example, apatite in which some calcium atoms of calcium hydroxyapatite are replaced with titanium atoms by a technique such as ion exchange.

  An air conditioner according to a fourth aspect of the present invention is any one of the first to third aspects of the air conditioner, wherein the active species generating unit includes a discharge electrode and a counter electrode. The air filter is disposed adjacent to at least one of the discharge electrode and the counter electrode.

  Here, since the air filter is disposed adjacent to at least one of the discharge electrode and the counter electrode, active species having very high activity can be provided to the air filter at a high concentration. Therefore, the rate at which odor molecules, bacteria, viruses, and the like are decomposed, killed, or inactivated can be further increased.

  According to the air conditioner pertaining to the first aspect of the present invention, it is possible to obtain a long-life air filter while expanding the dust collection area and efficiently adsorbing dust and the like, reducing pressure loss.

  In addition, the configuration can be simplified by eliminating the need for a light source for activating the photocatalyst.

  Furthermore, it becomes possible to further increase the rate of decomposing, killing, or inactivating odor molecules, fungi, and viruses.

  According to the air conditioner pertaining to the second invention, it is possible to increase the efficiency of decomposing, killing, or inactivating odor molecules, bacteria, viruses, and the like.

  According to the air conditioner pertaining to the third invention, the efficiency of decomposing, killing, or inactivating odor molecules, bacteria, viruses, and the like can be further increased.

  According to the air conditioner pertaining to the fourth aspect of the invention, it is possible to further increase the rate at which odor molecules, bacteria, viruses, and the like are decomposed, killed, or inactivated.

Further, the front panel 21 is provided with an ultrasonic aperture 24 for sending ultrasonic waves generated from the ultrasonic generator to a wide range in the room.

  Further, the height of the front panel 21 is longer than the depth of the air purifier 1.

<Configuration in the main body casing 11>
A fan motor (blower unit) 30 and a blower fan (blower unit) 31 that is rotationally driven by the fan motor 30 are provided in the main body casing 11 (see FIG. 3). As the fan motor 30, an inverter motor whose frequency is controlled by an inverter circuit is employed. A centrifugal fan is adopted as the blower fan 31. For this reason, the blower fan 31 sucks air from the rotation axis direction (first space side) and blows air from the rotation center toward the radially outer side (second space side).

  Moreover, the air cleaner 1 has the 1st partition plate 51 in the back | inner side (downstream side in an air flow path) of the space where the air purification unit 40 mentioned later is attached (refer FIG. 9). The first partition plate 51 partitions the first space on the upstream side of the blower fan 31 and the second space on the downstream side of the blower fan 31. The air purification unit 40 is accommodated in the first space on the upstream side of the blower fan 31. In the second space on the downstream side of the blower fan 31, the fan motor 30, the blower fan 31, and the scroll 52 formed along the side surface (circumferential direction around the rotation axis of the blower fan) are stored.

<Air purification unit 40>
As shown in FIG. 3, the air purifier 1 has foreign matter contained in the indoor air sucked from each suction port (upper surface suction port 13, side suction port 14, front suction port 22) inside the main body casing 11. An air purifying unit 40 is provided.

  The air cleaning unit 40 includes a pre-filter 41, a discharge part (active species generation part) 42, a photocatalytic filter (pleated air filter) 43, and a plasma catalyst filter 44.

[Prefilter 41]
The pre-filter 41 is disposed on the most upstream side in the air flow, and removes relatively large dust and dust. As shown in FIG. 5, the prefilter 41 includes a net 410 and a frame 411 that holds the net 410. The net 410 is a thread-like resin net made of polypropylene (hereinafter referred to as PP), to which relatively large dust contained in the air sucked into the main body casing 11 adheres. Moreover, the fiber which comprises the net | network 410 consists of the coating layer 414 comprised by PP similarly to the core 410a comprised by PP, as shown in FIG. A visible light type photocatalyst 412 and catechin 413 are supported on the coating layer 414 so as to be exposed to the air side. The visible light type photocatalyst 412 contains titanium oxide whose photocatalytic action is activated by visible light, and removes fungi and viruses such as fungi and bacteria contained in dust attached to the net 410. Catechin 413 is a kind of polyphenol and is a generic name for epicatechin, epigallocatechin, epicatechin gallate, epigallocatechin gallate, and the like. The catechin 413 suppresses the growth of fungi such as mold fungi and bacteria contained in the dust attached to the net 410 and inactivates viruses.

[Discharge part 42]
The discharge part 42 is mainly composed of a counter electrode 422, an ionization line 421, and a streamer discharge electrode 423. The counter electrode 422 is a metal plate having a square-wave cross section, and includes a real electrode portion 422a that substantially functions as an electrode and a plurality of slit portions 422b. In addition, the slit part 422b plays the role which flows air on the back side (refer the white arrow of Fig.4 (a)). The ionization line 421 is disposed upstream of the counter electrode 422 in the air flow direction (see the white arrow in FIG. 4A). At this time, the ionization lines 421 are arranged one by one between the actual electrode portions 422a. Further, the ionization line 421 is formed of a fine diameter tungsten wire or the like and used as a discharge electrode. The streamer discharge electrode 423 includes an electrode holding portion 423a and an electrode portion 423b, and the electrode portion 423b is fixed to the electrode holding portion 423a with a resin interposed therebetween. The streamer discharge electrode 423 is arranged downstream of the counter electrode 422 in the air flow direction (see the white arrow in FIG. 4C), as shown in FIG. 4C.

Of these electrodes 421, 422, and 423, the counter electrode 422 and the ionization line 421 serve to charge relatively small dust floating in the air that has passed through the prefilter 41. On the other hand, the counter electrode 422 and the streamer discharge electrode 423 play a role of generating active species to be supplied to a titanium apatite-carrying filter 431 described later. Hereinafter, combinations of the respective electrodes will be described in detail.

(Counter electrode and ionization wire)
In the discharge part 42, when a high voltage is applied between the ionization line 421 and the actual electrode part 422a, a discharge is generated between the electrodes 421 and 422. As a result, dust passing between the electrodes 421 and 422 is charged with a positive charge. The charged dust is supplied rearward through the slit portion 422b and is electrostatically adsorbed by the electrostatic filter 430 of the photocatalytic filter 43 described later. At this time, since viruses and bacteria contained in the dust are charged, the efficiency of adsorbing the viruses and bacteria to titanium apatite described later is increased.

(Counter electrode and streamer discharge electrode)
In the discharge unit 42, when a DC, AC, or pulse discharge voltage is applied between the streamer discharge electrode 423 and the counter electrode 422, streamer discharge is generated between the electrodes 422 and 423. Thus, when streamer discharge occurs, low-temperature plasma is generated in the discharge field. The low-temperature plasma generates radical species such as fast electrons, ions, ozone, and hydroxy radicals, and other excited molecules (excited oxygen molecules, excited nitrogen molecules, excited water molecules). Then, radical species such as ions, ozone, and hydroxy radicals, and other active species such as excited molecules (excited oxygen molecules, excited nitrogen molecules, excited water molecules) ride on the air flow, and titanium of the photocatalytic filter 43 described later. This is supplied to the apatite-carrying filter 431.

  These active species have a very high energy level, and even before reaching the titanium apatite-carrying filter 431, they decompose and decompose small organic molecules such as ammonia, aldehydes and nitrogen oxides contained in the air. Has the ability to deodorize.

[Photocatalytic filter 43]
The photocatalytic filter 43 is formed in a pleat shape, and is formed by bonding an electrostatic filter 430 and a titanium apatite-carrying filter 431 as shown in FIG. The photocatalytic filter 43 is disposed such that the electrostatic filter 430 faces the upstream side of the air flow by the blower fan 31 and the titanium apatite-carrying filter 431 faces the downstream side of the air flow. The electrostatic filter 430 adsorbs dust or the like that is charged when passing through the discharge unit 42. The titanium apatite-carrying filter 431 adsorbs dust or the like that passes through the electrostatic filter 430. The titanium apatite-carrying filter 431 is formed of PP fibers carrying titanium apatite, like the pre-filter 41. Titanium apatite is apatite in which some calcium atoms of calcium hydroxyapatite are replaced with titanium atoms by a technique such as ion exchange. This titanium apatite has the property of specifically adsorbing viruses, molds, bacteria, etc. contained in dust and the like. The titanium apatite has a photocatalytic function activated by active species supplied from the discharge section 42, and inactivates or kills viruses, fungi, bacteria, and the like.

  Further, since the photocatalytic filter 43 is formed in a pleat shape as shown in FIG. 8A, it can be easily folded in accordance with the fold as shown in FIG. 8B. For this reason, the photocatalytic filter 43 is stored in a replacement filter storage portion A formed below the first partition plate 51 in a folded state (see FIG. 9).

  As shown in FIG. 9, the replacement filter storage portion A has a second partition plate 53 erected in a direction perpendicular to the first partition plate 51 as an upper surface, and a lower surface and side surfaces as main body casings. 11 is a storage space having a lower surface and side surfaces, and six replacement photocatalyst filters 43 shown in FIG. 8B are stored one by one in a packed state.

[Plasma catalyst filter 44]
The plasma catalyst filter 44 carries anatase type titanium dioxide. The plasma catalyst filter 44 adsorbs viruses and fungi in the air that have not been adsorbed by the photocatalytic filter 43. In the plasma catalyst filter 44, the adsorbed bacteria and viruses are killed or inactivated by the titanium dioxide activated by the active species.

[Features of air purification unit]
(1)
The air cleaning unit 40 of this embodiment includes a prefilter 41, a discharge unit 42 that generates active species, a pleated photocatalytic filter 43, and a plasma catalytic filter 44.

  Usually, an air cleaner equipped with a photocatalytic filter requires a light source for activating the photocatalyst. For this reason, in order to effectively irradiate the photocatalyst with light from the light source, a planar filter has been adopted as the photocatalytic filter. However, such a planar filter has the disadvantages that the dust collection area is narrow and the pressure loss is large.

  Therefore, in the air cleaning unit 40 of this embodiment, a pleated filter is used as the photocatalytic filter 43 instead of a planar filter.

  Thereby, it is possible to obtain an air cleaning unit that has a large dust collection area and a small pressure loss in the filter as compared with a flat filter. As a result, it is possible to provide an air cleaning unit having a photocatalytic filter having a long life by efficiently collecting dust and dirt in the air.

  Further, the air cleaning unit 40 of the present embodiment uses an active species generation unit instead of a light source as a photocatalyst activation means.

  Accordingly, the photocatalyst can be activated by the active species, so that the configuration can be simplified by removing the light source from the constituent elements.

(2)
In the air cleaning unit 40 of the present embodiment, the photocatalytic filter 43 has a titanium apatite-carrying filter 431.

  Thereby, odor molecules, bacteria, viruses and the like contained in the air passing through the filter can be more strongly adsorbed, and the odor molecules and the like can be inactivated more effectively.

(3)
In the air cleaning unit 40 of this embodiment, the titanium apatite-carrying filter 431 constituting the photocatalytic filter 43 has a photocatalytic function.

  Thereby, the photocatalytic function is activated by the active species supplied from the discharge unit 42, and viruses, molds, bacteria, and the like can be inactivated or killed.

(4)
In the air cleaning unit 40 of the present embodiment, the discharge unit 42 includes a counter electrode 422 and a streamer discharge electrode 423. The photocatalytic filter 43 is disposed on the downstream side of the discharge unit 42 and adjacent to the counter electrode 422.

  Thereby, the active species generated in the discharge part 42 can be supplied to the photocatalytic filter 43 in a high concentration and high activity state. Therefore, odor molecules, bacteria, viruses and the like contained in the air passing through the air cleaner 1 can be inactivated efficiently.

(5)
In the air cleaning unit 40 of the present embodiment, the discharge part 42 has a streamer discharge electrode 423.

  Thereby, for example, an active species having a high energy level can be generated by causing a streamer discharge that forms a stronger discharge field than other plasma generators such as a glow discharger and a barrier discharger. Therefore, odor molecules and bacteria can be efficiently decomposed, killed, and inactivated.

(6)
The air cleaner 1 according to the present embodiment includes the air purification unit 40 described above and a blower unit including a fan motor 30, a blower fan 31, and a scroll 52.

  Thereby, since the photocatalyst can be activated by the active species, an air cleaner with a simplified configuration can be provided by removing the light source from the constituent elements. Further, since a pleated filter can be used, an air cleaner having a large dust collection area and a small pressure loss in the filter can be provided as compared with a planar filter. As a result, it is possible to provide an air cleaner having a photocatalytic filter having a long life by efficiently collecting dust and dirt in the air.
