<First Embodiment>
<Configuration of deodorizing function reproducing device>
An appearance of the deodorizing function reproducing apparatus 1 according to the first embodiment of the present invention is shown in FIG. The deodorizing function regenerating apparatus 1 performs a regeneration process of the deodorizing agent 4 that has been used for a certain period of time and has a reduced deodorizing effect. The deodorizing function reproducing device 1 includes a deodorizing agent casing 2, a streamer discharge unit 3, a high voltage unit 30, a blower device 5, and a control unit 6.

(1) Deodorant casing The deodorant casing 2 constitutes the outer surface of the deodorizing function reproducing device 1 and includes the streamer discharge unit 3, the blower device 5, and the control unit 6. The deodorant casing 2 includes a main body 2a and a door 2b. The door 2b can be opened and closed, and the deodorant 4 can be taken in and out from the opening of the deodorant casing 2 where the door 2b is opened.

(2) Streamer discharge part The streamer discharge part 3 is mainly composed of a counter electrode 32 and a streamer discharge electrode 33, as shown in FIGS. 2 (a), 2 (b), and 2 (c). Is done. The counter electrode 32 is a metal plate having a square-wave cross section, and is composed of an actual electrode portion 32a that substantially functions as an electrode and a plurality of slit portions 32b. In addition, the slit part 32b plays the role which flows air on the back side (refer the white arrow of Fig.2 (a)). The streamer discharge electrode 33 includes an electrode bar 33a and a needle electrode 33b. The needle electrode 33b is fixed so as to be substantially orthogonal to the electrode rod 33a. The streamer discharge electrode 33 is disposed downstream of the counter electrode 32 in the air flow direction (see the white arrow in FIG. 2C), as shown in FIG. 2C. At this time, the streamer discharge electrode 33 is disposed so that the needle electrode 33 b faces the actual electrode portion 32 a of the counter electrode 32.

  When a direct current, alternating current, or pulse discharge voltage is applied between the streamer discharge electrode 33 and the counter electrode 32 in the discharge section 32, as shown in FIG. Streamer discharge occurs. 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, these active species are supplied to the deodorizing agent 4 along the air flow, and the deodorizing performance of the deodorizing agent 4 is regenerated.

  These active species have a very high energy level and have the ability to decompose and deodorize small organic molecules such as aldehydes contained in air, ammonia, and nitrogen oxides.

  A high voltage unit 30 is connected to the streamer discharge unit 3. The high voltage unit 30 can adjust the generation amount of the active species generated by the streamer discharge unit 3 by controlling the discharge amount (see FIGS. 1 and 3).

(3) Blower Device The blower device 5 sends the active species generated by the streamer discharge unit 3 to the deodorizer 4. As shown in FIG. 1, the blower 5 includes a fan motor 5a and a blower fan 5b. The blower fan 5b is rotationally driven by a fan motor 5a. As the fan motor 5a, an inverter motor whose frequency is controlled by an inverter circuit is employed.

(4) Control Unit The deodorizing function reproducing device 1 further includes a control unit 6 composed of a microprocessor. As shown in FIG. 3, the controller 6 is connected to a ROM 6a for storing control programs and various parameters, a RAM 6b for temporarily storing variables being processed, and the like. In addition, a temperature sensor 6c, a humidity sensor 6d, a gas sensor 6e, a switch 7, a display panel 8, an operation panel 9a, and a remote controller 9b are connected to the control unit 6.

  Various sensors such as the temperature sensor 6c, the humidity sensor 6d, and the gas sensor 6e output detection signals of the sensors to the control unit 6. The gas sensor 6e can measure the concentration of gas generated from odor molecules decomposed by active species and harmful gas components. With these various sensors, the regeneration status of the deodorizer 4 can be judged and the regeneration time can be automatically adjusted.

  In the switch 7, the discharge of the streamer discharge unit 3 is turned ON / OFF. The switch 7 is turned off when the door 2b is opened and turned on when the door 2b is closed. Therefore, it is possible to start and end the regeneration process of the deodorizer 4 by opening and closing the door 2b. Since the switch is turned off when the door 2b is opened, the generation of active species by the streamer discharge unit 3 is stopped when the user opens the door 2b. For this reason, the user can operate safely.

  The display panel 8 displays monitor information (reproduction processing information), timer information, maintenance information, and the like by various sensors 6c to 6e, and can be viewed from the outside through a display panel opening (not shown) by a user or the like. ing. Moreover, this display panel 8 can be comprised with a liquid crystal display panel, LED, another display element, or these combination.

  The user can turn ON / OFF the switch 7 by using the operation panel 9a and the remote control 9b. Further, the operation panel 9a and the remote controller 9b allow the user to change the operation mode such as the deodorizer regeneration operation and the deodorization operation, adjust the processing time of the regeneration operation, and start and end the operation in various operation modes.

  Further, the control unit 6 is connected to the fan motor 5 a and the high voltage unit 30. The control unit 6 can control the amount of air generated by the fan motor 5a and the amount of discharge related to the generation of active species by the high voltage unit 30 according to the user's operation and the detection results of the various sensors 6c to 6e.

<Features of First Embodiment>
(1)
In the deodorizing function reproducing apparatus 1, a deodorizing agent 4 used at an arbitrary place is installed in a deodorizing agent casing 2. In addition, this apparatus generates active species by the streamer discharge unit 3. Then, the active species decomposes at least one of the odor molecules and harmful gas components adsorbed on the deodorizer 4 to regenerate the deodorizer 4.

  Therefore, since the deodorizer 4 that has been conventionally required to be replaced at regular intervals can be reused, it is possible to suppress generation of dust, generation of sewage due to washing, and the like. For this reason, when performing the reproduction | regeneration processing of the deodorizing agent 4, the burden to an environment can be reduced. In addition, since it can be reliably played back in a short time with a simple operation, usability can be improved.

(2)
The deodorizing function reproducing device 1 further includes a blower 5 that generates wind in the deodorizing agent casing 2. Therefore, the active species can be actively touched to the deodorizing agent 4. For this reason, the effect of the regeneration process of the deodorizer 4 can be improved.

(3)
In the deodorizing function regenerating apparatus 1, the streamer discharge unit 3 generates active species for a predetermined time. Therefore, the regeneration process of the deodorizer 4 ends when a predetermined time has elapsed. For this reason, the user can end the regeneration process of the deodorant 4 without starting the regeneration process after starting the regeneration process of the deodorant 4.

  Moreover, the predetermined time which produces | generates this active species can be adjusted. The regeneration level of the deodorizer 4 increases as the regeneration process time increases, and decreases as the regeneration process time decreases. Therefore, the user can adjust the regeneration processing level according to the degree of contamination of the deodorizer 4 by setting the regeneration processing time. For this reason, since it can suppress that regeneration processing becomes excessive with respect to the degree of dirt of deodorizer 4, the energy consumed for regeneration processing can be controlled. Moreover, since it is possible to eliminate the lack of regeneration processing with respect to the degree of contamination of the deodorizer 4, the deodorizer 4 can be more reliably regenerated.

(4)
The deodorizing function reproducing apparatus 1 further includes a temperature sensor 6c, a humidity sensor 6d, a gas sensor 6e, and the like that can detect the processing status of the regeneration process. Therefore, the streamer discharge part 3 can adjust predetermined time according to the processing condition which these various sensors 6c-6e detected. For this reason, a regeneration process suitable for the degree of contamination of the deodorizer 4 can be automatically performed. This eliminates the need for the user to set the playback processing time, thereby reducing the burden on the user's operation and allowing the user to easily perform the playback process. Moreover, since it can suppress that regeneration processing becomes excess with respect to the stain | pollution | contamination of the deodorizing agent 4, the energy consumed by regeneration processing can be suppressed. Moreover, since it is possible to solve the shortage of the regeneration process for the dirt of the deodorizer 4, the deodorizer 4 can be more reliably regenerated.

  The deodorizing function reproducing apparatus 1 further includes a display panel 8 capable of displaying the processing status of the reproduction processing detected by the various sensors 6c to 6e. Therefore, the processing status of the reproduction process can be visually confirmed. For this reason, the user can confirm the processing status in real time, and can perform a reproduction process according to the status.

(5)
The deodorizing function regeneration device 1 further includes a switch 7 that can determine the start and end of the regeneration process of the deodorant 4. The streamer discharge unit 3 starts generating active species when the switch 7 is turned on, and ends generating active species when the switch 7 is turned off. Therefore, in this deodorant regeneration process, the start and end of the regeneration process of the deodorant 4 can be performed by turning on / off the switch 7. For this reason, the user can determine the timing of the start and end of the reproduction process based on his / her judgment.

  Further, in the deodorizing function reproducing device 1, the door 2 b provided in the deodorizing agent casing 2 serves as a switch 7. Therefore, the switch 7 can be turned on and off by opening and closing the door 2b. For this reason, the streamer discharger 3 can determine the start and end of the regeneration process of the deodorizer 4 by opening and closing the door 2b. As a result, it is not necessary to create a part for forming the switch 7, and the product cost can be reduced. Moreover, since the switch 7 is turned OFF when the door 2b is opened, the generation of active species by the streamer discharge unit 3 is stopped when the user opens the door 2b. For this reason, the user can operate safely.

A. Main Body The main body 12 has a top suction port 14, a side suction port 15, and a blowout port 16. The upper surface suction port 14 and the side surface suction port 15 are substantially rectangular openings for sucking room air into the air cleaner 10 in order to clean the room air in the air cleaner 10. The upper surface suction port 14 is provided at the front side end of the upper surface of the main body 12 that is the same as the surface on which the blowout port 16 is provided. The side suction ports 15 are a pair of openings provided on the left and right sides of the main body 12. The blowout port 16 is provided at the rear side end of the upper surface of the main body 12. The blowout port 16 is an opening for blowing the cleaned air from the air cleaner 10 into the room. Moreover, the main-body part 12 has the opening part 19 in which the deodorizing agent 4a can be withdrawn / inserted in the side surface, and the deodorizing agent casing 20 mentioned later is accommodated in the opening part.

B. Front Panel The front panel 13 is provided in front of the main body 12 and covers the filter unit 40 installed inside the main body 12. The front panel 13 has a front suction port 17 and a display panel opening 18. The front suction port 17 is a substantially rectangular opening for sucking indoor air provided in a substantially central portion of the front panel 13 into the air cleaner 10. The display panel opening 18 is provided so that a display panel 53 described later can be seen from the outside of the air purifier casing 11.

(2) Blower The blower 44 sucks room air from each suction port (upper surface suction port 14, side surface suction port 15, and front suction port 17), and blows clean air from the blowout port 16. The blower 44 is provided inside the air purifier casing 11, and is configured such that the indoor air sucked from each suction port passes through the filter unit 40. In addition, as shown in FIG. 2, the blower device 44 includes a fan motor 44a and a blower fan 44b. The blower fan 44b is rotationally driven by a fan motor 44a. As the fan motor 44a, an inverter motor whose frequency is controlled by an inverter circuit is employed. A centrifugal fan is employed as the blower fan 44b.

(3) Control part The air cleaner 10 is further provided with the control part 50 comprised with a microprocessor. As shown in FIG. 7, the controller 50 is connected to a ROM 50a that stores control programs and various parameters, a RAM 50b that temporarily stores variables being processed, and the like. In addition, a temperature sensor 50c, a humidity sensor 50d, a dust sensor 50e, a gas sensor 50f, a switch 51, an adjustment switch 52, and a display panel 53 are connected to the control unit 50.

  Various sensors such as the temperature sensor 50c, the humidity sensor 50d, the dust sensor 50e, and the gas sensor 50f output detection signals of the sensors to the control unit 50. The dust sensor 50e irradiates light into the air to be introduced, detects the amount of light that reaches the light receiving element by being scattered by smoke, dust, pollen, and other particles contained in the air, and detects the concentration of particles such as dust Can be measured. The gas sensor 50f can measure the concentration of gas generated from odor molecules and harmful gas components decomposed by active species. By these various sensors, the regeneration status of the deodorizer 4a can be judged and the regeneration time can be automatically adjusted.

  The switch 51 can start and end the regeneration process of the deodorizer 4a. When the door 20b is opened, the switch 51 is turned off, and when the door 20b is closed, the switch 51 is turned on. Therefore, when the user opens the door 20b, the generation of active species by the streamer discharge part 3a is stopped. For this reason, the user can operate safely.

  The adjustment switch 52 increases or decreases the amount of active species generated by the streamer discharger 3a. The adjustment switch 52 is turned off when the deodorizing agent 4 a is taken out from the deodorizing agent casing 20, and turned on when the deodorizing agent 4 a enters the deodorizing agent casing 20. When the adjustment switch 52 is turned off, the amount of active species generated in the streamer discharge part 3a decreases, and when the adjustment switch 52 is turned on, the amount of active species generated in the streamer discharge part 3a increases. Therefore, when the deodorizing agent 4a is not in the deodorizing agent casing 20, it is possible to provide active species only for the various filters. For this reason, the amount of active species generated for the regeneration process of the deodorizer 4a can be increased or decreased by turning the adjustment switch 52 on / off.

  The display panel 53 displays the operation mode, monitor information from the various sensors 50c to 50f, timer information, maintenance information, and the like, so that the user can visually check the display panel opening 18 from the outside. The display panel 53 can be constituted by a liquid crystal display panel, LEDs, other display elements, or a combination thereof.

  The user can turn ON / OFF the switch 51 and the adjustment switch 52 by using the operation panel 54a and the remote controller 54b. Further, the operation panel 54a and the remote controller 54b allow the user to change the operation mode such as the deodorizer regeneration operation and the deodorization operation, adjust the processing time of the regeneration operation, and start / end the operation in various operation modes.

  Furthermore, the control unit 50 is connected to the fan motor 44a and the high voltage unit 30a. The control unit 50 can control the amount of air generated by the fan motor 44a and the amount of discharge related to the generation of active species by the high voltage unit 30a according to the user's operation and the detection results of the various sensors 50c to 50f.

(4) Filter unit The filter unit 40 is provided inside the air purifier casing 11 and removes particulates contained in room air sucked from the suction ports 14, 15, and 17. As shown in FIG. 5, the filter unit 40 includes a pre-filter 41, a streamer discharge part 3 a, a deodorant casing 20, a photocatalyst filter 42, and a plasma catalyst filter 43. In the filter unit 40, room air sucked from the suction ports 14, 15, and 17 passes through the filter unit 40 in the order of the pre-filter 41, the streamer discharge unit 3 a, the deodorant casing 20, the photocatalyst filter 42, and the plasma catalyst filter 43. It is configured as follows.

A. Prefilter The prefilter 41 is a filter for removing relatively large dust from the air sucked into the air purifier casing 11 by the blower 44. The pre-filter 41 has a net part and a frame (not shown). The net part is a thread-like resin net made of polypropylene (hereinafter referred to as PP), and relatively large dust contained in the air sucked into the air cleaner casing 11 adheres to the net part. Moreover, the fiber which comprises a net part consists of the coating layer comprised with PP similarly to the core comprised with PP. A visible light type photocatalyst and catechin are supported on the coating layer so as to be exposed to the air side. The visible light type photocatalyst contains titanium oxide or the like whose photocatalytic action is activated by visible light, and removes bacteria and viruses such as fungi and bacteria contained in dust attached to the net part. Catechin is a kind of polyphenol and is a generic term for epicatechin, epigallocatechin, epicatechin gallate, epigallocatechin gallate, and the like. This catechin suppresses the growth of fungi such as fungi and bacteria contained in dust attached to the net part, and inactivates viruses.

B. Streamer discharge part The streamer discharge part 3a is mainly composed of a counter electrode 32, an ionization line 31, and a streamer discharge electrode 33, as shown in FIG. 2 (b), FIG. 6 (a), and FIG. 6 (b). Composed. The counter electrode 32 is a metal plate having a square-wave cross section, and is composed of an actual electrode portion 32a that substantially functions as an electrode and a plurality of slit portions 32b. In addition, the slit part 32b plays the role which flows air to the back side (refer the white arrow of Fig.6 (a)). The ionization line 31 is disposed upstream of the counter electrode 32 in the air flow direction (see the white arrow in FIG. 6A). At this time, the ionization lines 31 are arranged one by one between the actual electrode portions 32a. Further, the ionization line 31 is formed of a fine diameter tungsten wire or the like and used as a discharge electrode. The streamer discharge electrode 33 includes an electrode bar 33a and a needle electrode 33b. The needle electrode 33b is fixed so as to be substantially orthogonal to the electrode rod 33a. The streamer discharge electrode 33 is disposed downstream of the counter electrode 32 in the air flow direction (see the white arrow in FIG. 6B), as shown in FIG. 6B. At this time, the streamer discharge electrode 33 is disposed so that the needle electrode 33 b faces the actual electrode portion 32 a of the counter electrode 32.

  Of these electrodes 31, 32, and 33, the counter electrode 32 and the ionization line 31 serve to charge relatively small dust floating in the air that has passed through the prefilter 41. On the other hand, the counter electrode 32 and the streamer discharge electrode 33 play a role of generating active species to be supplied to a titanium apatite-carrying filter described later. Hereinafter, combinations of the respective electrodes will be described in detail.

(Counter electrode and ionization wire)
In the streamer discharge part 3a, when a high voltage is applied between the ionization line 31 and the actual electrode part 32a, a discharge is generated between the electrodes 31 and 32. As a result, dust passing between the electrodes 31 and 32 is charged with a positive charge. The charged dust is supplied rearward through the slit portion 32b and is electrostatically adsorbed by an electrostatic filter (not shown) described later. At this time, since viruses and bacteria contained in the dust are also charged, the efficiency of adsorbing viruses and bacteria to titanium apatite (not shown) described later is increased.

(Counter electrode and streamer discharge electrode)
In this streamer discharge part 3 a, when a DC, AC, or pulse discharge voltage is applied between the streamer discharge electrode 33 and the counter electrode 32, as shown in FIG. Streamer discharge occurs. 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). These active species are supplied to the titanium apatite-carrying filter along the air flow. Further, the deodorizing agent 4a is supplied to regenerate the deodorizing performance of the deodorizing agent 4a.

  These active species have a very high energy level, and even before reaching the titanium apatite-carrying filter or deodorant 4a, small organic molecules such as aldehydes contained in the air, ammonia, and nitrogen oxidation Ability to decompose / deodorize objects.

(High voltage unit)
A high voltage unit 30a is connected to the streamer discharge part 3a. The high voltage unit 30a can adjust the generation amount of the active species generated by the streamer discharge part 3a by controlling the discharge amount (see FIGS. 5 and 7).

C. Deodorant casing The deodorant casing 20 includes a main body 20a and a door 20b. The door 20b can be opened and closed, and the deodorant 4a can be taken in and out from the opening of the deodorant casing 20 where the door 20b is opened. When the door 20b is open, the switch 51 of the streamer discharge unit is forcibly turned off, and when the door 20b is closed, the switch 51 of the streamer discharge unit is turned on. For this reason, user safety is ensured.

D. Photocatalyst filter The photocatalyst filter 42 has a roll shape in which a length corresponding to a plurality of times is wound, and is configured to be pulled out and cut a dirty portion when the surface in use is dirty. This photocatalytic filter is formed by bonding an electrostatic filter and a titanium apatite-carrying filter (not shown). The electrostatic filter adsorbs dust or the like charged by the streamer discharge unit 3a. Dust that passes through the electrostatic filter adheres to the titanium apatite-carrying filter. The titanium apatite-carrying filter is formed of PP fibers carrying titanium apatite, like the prefilter. 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 deodorizing function regenerator further includes a deodorizing agent 4a that adsorbs at least one of odor molecules and harmful gas components floating in the air, and constitutes the air cleaner 10. Moreover, the air cleaner 10 is also a deodorizing function reproducing | regenerating apparatus using the deodorizing function. Therefore, in this air cleaner 10, it is possible to adsorb and deodorize at least one of odor molecules and harmful gas components floating in the air. Furthermore, since the deodorizing agent 4a, which has conventionally been required to be replaced at regular intervals, can be reused, it is possible to suppress the generation of trash and sewage due to washing. For this reason, when performing the reproduction | regeneration processing of the deodorizing agent 4a, the burden on an environment can be reduced. In addition, since it can be reliably played back in a short time with a simple operation, usability can be improved.

(2)
In the air cleaner 10, the adjustment switch 52 can adjust the increase / decrease in the amount of active species generated by the streamer discharger 3a. The streamer discharger 3a increases the generation amount of active species when the adjustment switch 52 is turned on, and decreases the generation amount of active species when the adjustment switch 52 is turned off. Therefore, when the active species other than the deodorizer 4a is used, the amount of the active species generated can be increased or decreased by the regeneration process of the deodorizer 4a by turning the adjustment switch 52 ON / OFF. Thereby, even if the adjustment switch 52 is turned OFF, the generation of the active species can be suppressed without ending. For this reason, wasteful consumption of energy can be suppressed.

  In the air cleaner 10, the adjustment switch 52 can be turned ON / OFF by putting the deodorant 4 a in and out of the deodorant casing 20. Therefore, it is possible to prevent wasteful discharge when the deodorant 4a is not contained in the deodorant casing 20. For this reason, consumption of useless energy can be suppressed.

The lower suction port 213 is provided at the lower front side end of the first main body casing 211 on the same surface as the surface on which the air outlet 212 is provided. The horizontal length of the lower suction port 213 is substantially the same as the horizontal length of the front panel 221. The side suction ports 214 are a pair of openings provided on the front sides of the left and right side portions of the first main body casing 211, respectively.

  The first main body casing 211 constitutes a main body casing 206 together with a front panel 221 described later. A main air flow path through which air that is sucked from the room through the suction port 213 and the suction port 214, is purified in the air cleaning unit 240, and blown out from the air outlet 212 into the room is inside the main body casing 206. And a bypass air passage for returning the air in the vicinity of the air outlet 212 to the upstream side, as shown in FIGS. 13, 14 and 16 (a), (b), (c). A main air flow F1 flowing through the air flow path and a bypass air flow F2 flowing through the bypass air flow path are generated by the blower fan 231.

"Rear" means "downstream side in the flow direction of the main air flow in the main air flow path". That is, the bypass air flow that flows through the bypass air flow path generally flows from the rear toward the front.

  Here, as shown in FIGS. 13, 14, and 16 (a), 16 (b), and 16 (c), the main air flow F <b> 1 flowing through the main air flow path is sucked from the lower suction port 213 and the side suction port 214. This is an air flow that cleans the generated air and blows it out from the air outlet 212. A bypass air flow F2 flowing through the bypass air flow path flows upward in the vicinity of the air outlet 212, and flows from the rear to the front in a state where the streamer discharge unit 263 is stored in the unit storage portion B. After flowing to the vicinity of the center of the front surface in the ionization unit 242, the ionization unit 242 descends and is guided to the front of a prefilter 241 described later.

  Here, as shown in FIG. 13, on the side surface portion of the first main body portion 203, as will be described later, a cartridge storage portion B <b> 2 for enabling replacement of the deodorization catalyst cartridge 249 is provided so as to be opened and closed. FIG. 13 shows an “open” state. Here, a limit switch B2S is provided in the cartridge storage portion B2, and the deodorization catalyst cartridge contact portion 249S of the deodorization catalyst cartridge 249 is set to the limit switch B2S in a state where the deodorization catalyst cartridge 249 is stored in the cartridge storage portion B2. It is comprised so that it may become the positional relationship to contact | abut. Thereby, in the air cleaner 200, as will be described later, the count of the counter 251 (see FIG. 25) proceeds while the deodorizing catalyst cartridge 249 is accommodated, and the regeneration process is completed by using the counter 251 for a predetermined time. Or the exchange can be notified.

[Blower fan 231 and fan motor 230]
The blower fan 231 and the fan motor 230 shown in FIGS. 14 and 15 generate a main air flow F1 flowing through the main air flow path and a bypass air flow F2 flowing through the bypass air flow path. As the blower fan 231, a centrifugal fan is employed. For this reason, the blower fan 231 sucks air from the rotation axis direction, and blows air from the rotation center toward the outside in the radial direction. The fan motor 230 rotationally drives the blower fan 231. As the fan motor 230, an inverter motor whose frequency is controlled by an inverter circuit is employed.

  In the first space on the upstream side of the blower fan 231, an air purifying unit 240 (see FIG. 15) described later is accommodated. In the second space on the downstream side of the blower fan 231, a scroll 233 is formed along the circumferential direction around the fan motor 230, the blower fan 231, and the side surfaces of the blower fan 231, that is, the rotation axis of the blower fan. It is stored. Then, the air blown from the blower fan 231 is sent out from the blower outlet 212 into the room along the scroll 233.

[Photocatalytic filter 243]
As shown in FIG. 15, the photocatalytic filter 243 is formed in a pleat shape, and is formed by laminating an electrostatic filter and a titanium apatite-carrying filter. The photocatalytic filter 243 is disposed so that the electrostatic filter faces the front side and the titanium apatite-carrying filter faces the rear side. The electrostatic filter adsorbs dust and the like charged when passing through a plasma ionization unit 242 described later. The titanium apatite-carrying filter adsorbs dust or the like that has passed through the electrostatic filter. This titanium apatite-carrying filter is formed of PP fibers carrying titanium apatite, like the pre-filter 241. 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 a streamer discharge unit 263 described later, and inactivates or kills viruses, molds, bacteria, and the like.

  Moreover, since this photocatalyst filter 243 is formed in a pleat shape, it can be easily folded according to the crease. For this reason, as shown in FIG. 12, the photocatalyst filter 243 is stored in a replacement filter storage portion A formed above in a folded state.

[Plasma catalyst filter 244]
The plasma catalyst filter 244 is disposed in front of the blower fan 231 and behind the photocatalytic filter 243. That is, the plasma catalyst filter 244 is disposed between the blower fan 231 and the photocatalyst filter 243. The plasma catalyst filter 244 carries anatase type titanium dioxide. The plasma catalyst filter 244 adsorbs viruses and fungi in the air that have not been adsorbed by the photocatalytic filter 243. In the plasma catalyst filter 244, the adsorbed bacteria and viruses are killed or inactivated by the titanium dioxide activated by the active species.

[Unit storage B]
As shown in FIG. 17, the unit storage portion B stores the streamer discharge unit 263 so as to be removable, and constitutes a part of the bypass air flow path through which the bypass air flow F2 flows. The unit storage portion B is composed of a unit storage body B1 and a cartridge storage portion B2 that is attached to the unit storage body B1 so as to be freely opened and closed.

As shown in FIG. 17, the cartridge storage unit B2 can replace the deodorizing catalyst cartridge 249 with the opening / closing portion opened. The cartridge housing portion B2 is provided with a deodorizing opening BO so that air can be transferred to and from the bypass air flow path of the unit housing body B1 when the deodorizing catalyst cartridge 249 is housed and closed. Thus, deodorization is achieved by adsorbing and decomposing odorous components targeting air flowing through the bypass air flow path.

  In addition, when this deodorization catalyst cartridge 249 is used for a certain period or longer, the effective adsorption surface area is reduced, and the deodorization effect is lowered. For this reason, the process which decomposes | disassembles and reproduces | regenerates the odor component adsorb | sucked to the surface, or the process to replace | exchange when the lifetime is reached is required.

  Here, the active species released from the streamer discharge unit 263 are bypassed through the four communication holes 272 (see FIG. 19), which will be described later, and the deodorizing opening BO (see FIG. 17). To the deodorizing catalyst cartridge 249. For this reason, the attached odor component that causes the deodorizing effect to decrease is decomposed by the active species. As a result, the deodorization catalyst cartridge 249 recovers the adsorption capability of the odor component, and can be used again as a deodorant and is regenerated.

  Even in the case of the deodorized catalyst cartridge 249 that is regenerated in this way, there is a limit to the state in which odor components can be adsorbed efficiently. Even if it does, it will be in the state which cannot stop the fall of a deodorizing capability. Therefore, here, as shown in FIG. 13, the limit switch B2S is provided in the unit storage portion B, and the limit switch B2S is in the state where the deodorization catalyst cartridge 249 is stored in the unit storage portion B. A structure that is pushed by the contact portion 249S is employed. In the air purifier 200, as shown in FIG. 25, the control unit 250 includes a counter 251 that counts only when the deodorizing catalyst cartridge 249 is stored in the unit storage unit B and the limit switch B2S is ON. It is provided in the form connected to. As a result, the time during which the deodorizing catalyst cartridge 249 is stored and used can be grasped, and the control unit 250 (see FIG. 25) determines whether or not the predetermined time has passed, thereby determining the replacement time. It is possible to grasp.

  The unit housing main body B1 is provided with main body side contacts 275a and 275b so as to be electrically connected in a state where the streamer discharge unit 263 is attached and to be energized. The main body side contacts 275a and 275b are formed of a metal plate, and are connected to a power source via a power circuit (not shown) and a power cord (not shown) housed in the first main body portion 203. . Thus, the main body side contacts 275a and 275b are provided so as to be separated in the longitudinal direction and in the vertical direction, and are brought into contact with a discharge unit side contact 271 to be described later, thereby supplying power to the streamer discharge unit 263 side. Transmits current from Here, the main body side contactor 275a is located on the rear side and contacts the streamer discharge electrode 270, and the main body side contactor 275b is located on the front side and comes into contact with the ground plate 273.

The contact covers 271G and 281G have a function of guiding insertion in the front-rear direction by sliding with a member on the unit storage portion B side when the streamer discharge unit 263 is inserted into the unit storage portion B. .

  As shown in FIG. 19, the discharge unit side contacts 271 and 281 are provided at positions corresponding to the positions of the contact covers 271G and 281G, respectively, in the longitudinal direction and in the vertical direction. In a state where the streamer discharge unit 263 is attached, the left side shown in FIG. 19 is the front of the air cleaner 200 and the right side is the rear. As described above, the discharge unit side contactor 271 and the discharge unit side contactor 281 are guided by the contactor covers 271G and 281G, respectively, while the streamer discharge unit 263 is inserted into the unit storage portion B, respectively.

[Discharge part 283]
The discharge part 283 is a main part that causes streamer discharge, and includes a streamer discharge electrode 270 and a ground plate 273.

(Streamer discharge electrode 270)
The streamer discharge electrode 270 is composed of a terminal attached to a portion where the metal plate 270 ′ is cut and raised, and a streamer discharge is generated between the streamer discharge electrode 270 and the ground plate 273 when a discharge voltage is applied. The streamer discharge electrode 270 and the metal plate 270 ′ are screwed to the discharge unit casing 269 via two insulating columns 271P by screws (271) passing through the inside of the insulating column 271P. One of the two insulating columns 271P is screwed so as to be in contact with the discharge unit side contact 271. Thus, in the state where the streamer discharge unit 263 is attached to the unit storage portion B and the discharge unit side contact 271 is in contact with the main body side contact 275a, the discharge unit side contact 271 is connected to the streamer discharge electrode via the screw 271S.

The ground plate 273 is screwed to the discharge unit casing 269 with two screws 281S (two) passing through the inside of the insulating column 281P via the two insulating columns 281P. One of the two insulating columns 281P is screwed so as to be in contact with the discharge unit side contact 281. As a result, when the streamer discharge unit 263 is attached to the unit housing portion B and the discharge unit side contact 281 is in contact with the main body side contact 275b, the discharge unit side contact 281 is connected to the ground plate 273 via the screw 281S. And become electrically connected.

  As described above, since the main body side contact 275a corresponding to the streamer discharge electrode 270 is located behind the main body, it is difficult for the user to reach it, and safety is ensured. Further, since the streamer discharge electrode 270 and the ground plate 273 are fixed to the discharge unit casing 269 made of resin through the insulating columns 271P and 281P, respectively, insulation is ensured.

  In the above configuration, the discharge unit casing 269 partitions the space where the streamer discharge electrode 270 and the ground plate 273 are disposed from the space where the contacts of the discharge unit side contacts 271 and 281 are disposed. . Thereby, the contacts of the discharge unit side contacts 271 and 281 are arranged in a space partitioned from the space where the streamer discharge electrode 270 and the ground plate 273 are arranged.

  As described above, the active species generated from the streamer discharge electrode 270 is released with respect to the bypass air flow flowing through the bypass air flow path.

The control unit 250 includes a temperature sensor 250c, a humidity sensor 250d, a dust sensor 250e, a gas sensor 250f, a limit switch B2S, a counter 251, a display panel 253, an operation panel 254a, a remote controller 254b, a fan motor 230, and a streamer discharge unit 263. Each is connected.

  Various sensors such as the temperature sensor 250c, the humidity sensor 250d, the dust sensor 250e, and the gas sensor 250f output detection signals of the sensors to the control unit 250. The dust sensor 250e irradiates light into the air to be introduced, detects the amount of light that reaches the light receiving element by being scattered by the smoke, dust, pollen, and other particles contained in the air, and the concentration of particles such as dust Can be measured. The gas sensor 250f can measure the concentration of gas generated from odor molecules decomposed by active species and harmful gas components. With these various sensors, the regeneration status of the deodorizing catalyst cartridge 249 can be judged and the regeneration time can be automatically adjusted.

  In the limit switch B2S, the switch is turned on by being pushed by the deodorizing catalyst cartridge contact portion 249S while the deodorizing catalyst cartridge 249 is housed in the cartridge housing portion B2 of the unit housing portion B. The deodorizing catalyst cartridge contact portion 249S is separated and the switch is turned off. And the control part 250 advances the count by the counter 251 when the switch of the limit switch B2S is ON, and does not advance the count by the counter 251 when the switch of the limit switch B2S is OFF. Thereby, the control unit 250 performs a process of determining whether or not the count by the counter 251 exceeds the number of times of replacement predetermined time data of the deodorizing catalyst cartridge 249 stored in the ROM 250a, and when determining that the count exceeds the predetermined number In addition, a process for notifying the display panel 253 of a sign notifying the replacement of the deodorizing catalyst cartridge 249 is performed.

  Further, the control unit 250 displays the display panel 253 until the amount of the odor component detected by the gas sensor 250f described above is less than the odor component allowable amount data stored in the ROM 250a when the limit switch B2S is turned on. In response to this, an indication that the deodorizing catalyst cartridge 249 is being regenerated is displayed. Note that the reproduction process here may be performed for a predetermined time predetermined by a timer or the like, and the display may be displayed for a predetermined time corresponding to this.

  In addition to the above display, the display panel 253 displays the operation mode, monitor information from the various sensors 250c to 250f, timer information, maintenance information, and the like. The display panel 253 can be formed of a liquid crystal display panel, LEDs, other display elements, or a combination thereof.

  When the user replaces the deodorization catalyst cartridge 249 with a new one by judging from the replacement notification from the display panel 253, the user inputs that the new one has been replaced with the operation panel 254a and the remote controller 254b, and the counter 251 The count can be reset. As a result, the total use time for the new deodorized catalyst cartridge 249 that has been replaced can be counted again. Further, the operation panel 254a and the remote controller 254b allow the user to change the operation mode such as the deodorizer regeneration operation and the deodorization operation, adjust the processing time of the regeneration operation, and start and end the operation in various operation modes.

  Further, the control unit 250 is connected to the fan motor 230 and the streamer discharge unit 263. The control unit 250 can control the amount of air generated by the fan motor 230 and the amount of discharge related to the generation of active species by the streamer discharge unit 263 in accordance with user operations, detection results of the various sensors 250c to 250f, and the like.

[Air cleaning action by the air cleaning unit 240]
As shown in FIG. 15, the air purifier 200 includes an air purifying unit 240 (air purifying unit), a streamer discharge unit 263, and a deodorizing catalyst, each including a prefilter 241, a plasma ionization unit 242, a photocatalytic filter 243, and a plasma catalytic filter 244. A cartridge 249 is provided, and the foreign matter contained in the indoor air sucked from each suction port (the lower suction port 213 and the side surface suction port 214) is removed to clean the air. Hereinafter, the air cleaning action by the air cleaning unit 240 will be described.

  The indoor air sucked from the lower suction port 213 and the side suction port 214 first passes through the filter portion 241a of the pre-filter 241. At this time, relatively large dust and dust are removed from the air. In addition, the action of the photocatalyst contained in the prefilter 241 and catechin suppresses the growth of fungi and viruses such as fungi and bacteria contained in the dust attached to the filter portion 241a of the prefilter 241, thereby inactivating the virus. Is done.

  The airflow that has passed through the prefilter 241 passes between the ionization line 266 and the counter electrodes 222 and 223. When a high voltage is applied between the ionization line 266 and the counter electrodes 222 and 223, a discharge is generated between the ionization line 266 and the counter electrodes 222 and 223. As a result, dust or the like contained in the air flow passing between the ionization line 266 and the counter electrodes 222 and 223 is positively charged.

  The air flow that has passed between the ionization line 266 and the counter electrodes 222 and 223 passes through the photocatalytic filter 243. At this time, dust or the like charged when passing through the plasma ionization unit 242 is adsorbed by the electrostatic filter. Further, dust or the like that has passed through the electrostatic filter is adsorbed by the titanium apatite-carrying filter. In addition, when passing through the ionization line 266 and the counter electrodes 222 and 223, viruses and bacteria contained in the dust are charged, so that the efficiency of adsorption of the virus and bacteria on the titanium apatite is increased.

  The air flow that has passed through the photocatalytic filter 243 passes through the plasma catalytic filter 244. In the plasma catalyst filter 244, viruses and fungi in the air that have not been adsorbed by the photocatalyst filter 243 are adsorbed.

  Passing through the plasma catalyst filter 244, the cleaned main air flow F1 is blown out from the blowout port 212 into the room. Further, part of the air that has passed through the plasma catalyst filter 244 flows as a bypass air flow F2 toward the bypass air flow path without being blown into the room.

  As described above, the streamer discharge unit 263 and the deodorizing catalyst cartridge 249 are provided in the bypass air flow path. In the streamer discharge unit 263, a DC, AC, or pulse discharge voltage is applied between the streamer discharge electrode 270 and the earth plate 273, and streamer discharge is generated between the streamer discharge electrode 270 and the earth plate 273. When streamer discharge occurs, low-temperature plasma is generated in the discharge field, and active species are generated in the discharge unit casing 269 and released into the bypass air flow F2. These active species have a very high energy level, and decompose and deodorize small organic molecules such as ammonia, aldehydes, and nitrogen oxides contained in the air even before reaching the photocatalytic filter 243. Have the ability to

  Here, the air passing in the vicinity of the streamer discharge electrode 270 is once cleaned in the prefilter 241, the plasma ionization unit 242, the photocatalytic filter 243, and the plasma catalytic filter 244. For this reason, it can prevent that dust collection, ammonium nitrate, etc. adhere to the terminal part of the streamer discharge electrode 270. Thereby, streamer discharge can be generated stably.

  The active species generated from the streamer discharge unit 263 is supplied to the deodorization catalyst cartridge 249 through the four communication holes 272 and the deodorization opening BO (see FIGS. 17 and 19) as described above, and is then supplied to the deodorization catalyst cartridge 249. 249 is played back. Specifically, the odor component adsorbed on the surface of the deodorization catalyst cartridge 249 is decomposed to improve the adsorption capability of the odor component.

  In this way, the bypass air flow F2 containing the active species passes through the bypass air flow path and is provided to the front and the rear of the prefilter 241, and acts on the dust attached to the prefilter 241 to be cleaned. be able to.

  Then, the air containing the active species passes between the ionization line 266 and the counter electrodes 222 and 223, and passes through the photocatalytic filter 243. At this time, dust or the like charged when passing through the plasma ionization unit 242 is adsorbed by the electrostatic filter. At this time, the titanium apatite-carrying filter adsorbs dust or the like that has passed through the electrostatic filter. At this time, the photocatalytic function of the titanium apatite is activated by the active species supplied from the streamer discharge unit 263, and thus viruses, molds, etc. Fungi, bacteria, etc. can be inactivated or killed.

  Further, in the plasma catalyst filter 244, viruses and bacteria in the air that have not been adsorbed by the photocatalytic filter 243 are adsorbed, and these bacteria and viruses are activated by titanium dioxide activated by air containing active species. Is killed or inactivated.

<Features of Fourth Embodiment>
In the air cleaner 200, the deodorization catalyst cartridge 249 is spatially continuous with respect to the bypass flow path through the four communication holes 272 and the deodorization opening BO. Therefore, the active species generated in the streamer discharge unit 263 is supplied to the deodorization catalyst cartridge 249 through the four communication holes 272 and the deodorization opening BO, and decomposes and regenerates the adsorbed odor components. be able to. Further, since the limit switch B2S is ON during reproduction, the control unit 250 notifies the user that reproduction is in progress by displaying on the display panel 253 that reproduction is in progress. Can do.

  Further, in the air cleaner 200, the control unit 250 can display the replacement time of the deodorizing catalyst cartridge 249 on the display panel 253 and refer to the user while referring to the count data by the counter 251. The counter 251 does not simply count the operation time of the air purifier 200, but only when the deodorizing catalyst cartridge 249 is actually stored in the cartridge storage unit B2 and the limit switch B2S is ON. is doing. For this reason, the user can grasp the more accurate replacement time of the deodorization catalyst cartridge 249.

  In this air cleaner 200, the bypass air flow passing through the streamer discharge unit 263 is purified in the main air flow path. For this reason, it can prevent that the dirt which exists in the air adheres to the discharge part 283. FIG. Thereby, plasma discharge can be performed stably. Thereby, since active species can be stably provided to the air cleaning unit 240, the air cleaning effect can be stabilized.
