Only the split channel introduction opening 49 is shown, but it is also formed on the right side). That is, the branch flow path introduction opening is formed so as to communicate with the discharge unit accommodation space S4. Here, the branch flow path is an air flow path communicating with the active species supply opening 13 and is formed on both sides of the air cleaning unit 2. The active species supply opening 13 is an opening for guiding the split air A1 supplied with the active species to the main air flow A. The shunt A1 to which the active species is supplied when passing through the discharge unit 50 is guided to the active species supply opening 13 by the shunt channel introduction opening and the shunt channel.

(1-4) Discharge unit 50
FIG. 5 is a schematic perspective view of the discharge unit 50.

  The discharge unit 50 generates active species by causing streamer discharge, and supplies the active species to the shunt A1 that passes through the discharge unit 50. The split flow A1 supplied with the active species by the discharge unit 50 is blown and joined to the main air flow A through the active species supply opening 13 described above. Specifically, the divided flow A <b> 1 supplied with the active species is blown out to the air flow before passing through the second prefilter 23 through the active species supply opening 13.

  The discharge unit 50 is detachably attached to the main body mounting unit 30 and includes a discharge unit casing 51. The discharge unit casing 51 is a rectangular parallelepiped member made of resin, and has an outer shape that matches the discharge unit accommodation space S4. The discharge unit casing 51 is composed of a plurality of (here, two) members. The plurality of members are connected by screwing or the like, and the inside of the discharge unit casing 51 can be inspected by removing the screws connecting the plurality of members. The discharge unit casing 51 is formed with a plurality of openings 51a. The shunt A1 that flows to the discharge unit 50 through the opening 51a flows to the shunt passage introduction opening.

  The discharge unit 50 mainly includes a discharge unit 152. The discharge part 152 is accommodated in the discharge unit casing 51. That is, the discharge unit 50 forms therein a discharge part accommodating space S5 for accommodating the discharge part 152 therein.

  The discharge part 152 is a main part that generates streamer discharge and generates active species, and includes a discharge electrode 152a and a counter electrode 152b.

  The discharge electrode 152 a includes a metal plate 155 and a discharge needle 156.

  The metal plate 155 has a substantially rectangular shape, and is attached to the back surface of the discharge unit casing 51 so as to be substantially parallel. That is, the metal plate 155 is attached so that the wide and long flat portion 155d faces the horizontal direction (front-rear direction). The metal plate 155 is attached to the discharge unit casing 51 by screwing both ends of the metal plate 155 to the back surface of the discharge unit casing 51 by a plurality of (here, two) screws 157 and 157. The metal plate 155 is connected to an insertion contact portion 52a for supplying a voltage to the discharge electrode 152a. The insertion contact portion 52 a extends to a position protruding outward from the outer surface of the discharge unit casing 51. The insertion contact portion 52a is covered with a first insulating member (not shown) having a cavity.

  The metal plate 155 has a plurality of (here, three) cut and raised portions 155a, 155b, and 155c. The cut-and-raised portions 155a, 155b, and 155c extend forward from the flat portion 155d (specifically, in the vertical direction with respect to the horizontal plane of the counter electrode 152b).

  The discharge needle 156 is a discharge member that performs discharge. The discharge needle 156 has a thin cylindrical shape and is made of an elastically deformable metal member (specifically, for example, tungsten). The discharge needle 156 extends laterally (in the left-right direction) from both side portions of the cut and raised portions 155a, 155b, and 155c. The diameter of the discharge needle 156 is 0.3 mm or less, preferably 0.2 mm or less. Further, the length of the discharge needle 156 is preferably 3.0 mm to 3.5 mm. By applying a voltage to the discharge needle 156, a streamer discharge is generated between the discharge needle 156 and the counter electrode 152b.

  The counter electrode 152b is made of a metal plate and has a substantially rectangular outer shape larger than the discharge electrode 152a. The counter electrode 152b is disposed so as to be separated from the discharge electrode 152a and to be opposed to the discharge electrode 152a (specifically, substantially parallel). The counter electrode 152b is also arranged so as to be substantially parallel to the discharge needle 156. Specifically, both ends of the counter electrode 152 b are screwed to the front surface of the discharge unit casing 51 by a plurality of (here, two) screws 158 and 158. In addition, an insertion contact portion 52b for supplying a voltage to the counter electrode 152b is connected to the counter electrode 152b. The insertion contact portion 52 b extends to a position that protrudes outward from the outer surface of the discharge unit casing 51. The insertion contact portion 52b is covered with a second insulating member (not shown) having a cavity around the insertion contact portion 52b.

The drive member 154 includes a drive gear 154b and a drive gear drive member 154c that drives the drive gear 154b. By driving the drive gear drive member 154, the drive gear 154b rotates. As the drive gear 154b rotates, the cleaning member 153 connected to the tip of the drive shaft 154a rotates via the drive shaft 154a. By the rotation of the cleaning member 153, the deposits attached to the discharge needle 156 are removed and cleaned.

(2) Operation of the Air Conditioner 1 When the fan 3 is rotated by driving the fan motor, the main air flow A described above is generated. Specifically, first, air in the air-conditioned space flows into the main body 10 through the suction ports 11 a and 11 b and the suction space 11 c of the main body 10. When the air flow flowing into the main body 10 through the suction ports 11a and 11b and the suction space 11c passes through the air cleaning unit 2, relatively large dust, fine dust, odor and the like are removed. Here, since the divided flow A1 to which the active species is supplied by passing through the discharge unit 50 is blown out to the air flow before passing through the second prefilter 23, the airflow passing through the second prefilter 23 is Contains active species. Therefore, the dust and odor adsorbed by the HEPA filter 24 and the deodorizing filter 25 located on the downstream side of the main airflow from the second prefilter 23 are decomposed by the active species contained in the airflow that has passed through the second prefilter 23. Is done.

  Then, the air flow cleaned by the air cleaning unit 2 flows into the fan 3 from the direction of the rotation axis of the fan 3 through a fan suction port (not shown). The air flow that has flowed into the fan 3 is redirected upward and is guided to the air outlet 12 through a fan outlet (not shown). The air flow guided to the air outlet 12 is blown upward through the air outlet 12, that is, supplied to the conditioned space outside the main body 10. A part of the air flow (corresponding to the blowout flow) blown out through the air outlet 12 flows to the main body attachment unit 30 via the intake port 43 as a diversion A1 and is attached to the main body attachment unit 30. The discharge unit 50 passes through the active species supply opening 13 and merges with the air flow before passing through the second prefilter 23.

(3) Flow of the diversion A1 in the main body mounting unit 30 In a state where the discharge unit 50 is accommodated in the discharge unit accommodation space S4, the operation of the air conditioner 1 is started. At this time, the discharge part accommodation space S5 formed by the discharge unit 50 is adjacent to the contact part accommodation spaces S2 and S3, and is located downstream of the branch part A1 with respect to the contact part accommodation spaces S2 and S3.

  The flow of the diversion A1 in the main body mounting unit 30 in this state will be described below with reference to FIGS. 4 and 5. The arrows shown in FIGS. 4 and 5 indicate the flows of the diversions A1, A1a, A1b, A1c, A1d, and A1e.

  First, the main air flow A is generated by driving the fan motor of the fan 3. Then, only by the wind pressure of the fan 3, a part of the blowout flow blown out from the blowout port 12 flows into the mounting unit main body 40 through the intake port 43 as a diversion A1. The diversion A1 is divided above the diversion guide portion 44 into diversions A1a and A1b that divert to the left and right and a diversion A1c that flows to the front. Specifically, the diversion A1 is divided into a diversion A1a that flows to the contact portion accommodation space S2, a diversion A1b that flows to the contact portion accommodation space S3, and a diversion A1c that flows to the discharge unit 50. The diversion flows A1a and A1b flowing into the contact portion accommodating spaces S2 and S3 are forward (that is, the discharge unit) via a gap at the time of insertion between the insertion contact portions 52a and 52b and the insertion openings 46a and 46b. 50 side). The diverted flow A1c that has flowed to the discharge unit 50 joins the diverted flows A1a and A1b that flow forward through the gap at the time of insertion to become a diverted flow A1. Then, the divided flow A1 where the divided flows A1a, A1b, A1c merge in the discharge unit 50 passes through the plurality of openings 51a formed in the discharge unit casing 51 constituting the discharge unit 50, and is divided again to be divided into the divided flows A1d, A1e. As shown in FIG. Then, the branch flows A1d and A1e guided to the branch channel introduction opening 49 flow to the branch channel through the branch channel introduction opening. Then, the split flows A1d and A1e that have flowed to the branch flow path merge with the air flow before passing through the second prefilter 23 via the active species supply opening 13 communicating with the split flow path, and become the main air flow A. .

  In the present embodiment, the air pressure in the contact portion accommodating spaces S2, S3 becomes higher than the air pressure in the discharge portion accommodating space S5 by flowing the divided flow A1 as the divided flows A1a, A1b to the contact portion accommodating spaces S2, S3. I am doing so.

(4) Features (4-1)
For example, a product generated in a discharge part as disclosed in Patent Document 1 (Japanese Patent Laid-Open No. 2005-300111) has a strong oxidizing power. For this reason, when a product touches a contact, we are anxious about a contact corroding.

  Therefore, in the present embodiment, the air flow (divided flow A1) is made to flow in the direction from the contact portion accommodating spaces S2 and S3 toward the discharge portion accommodating space S5. That is, the contact portion accommodating spaces S2 and S3 are located on the upstream side of the airflow of the diversion A1 with respect to the discharge portion accommodating space S5. Therefore, it can suppress that the product (active species) produced | generated in the discharge part 152 flows into contact part accommodation space S2, S3. Accordingly, corrosion of the fixed contact portions 47a and 47b and the insertion contact portions 52a and 52b (contact points) can be suppressed.

  Moreover, since corrosion of the fixed contact portions 47a and 47b and the insertion contact portions 52a and 52b can be suppressed by such a simple method, the fixed contact portions 47a and 47b and the insertion contact portions 52a and 52b are separately sealed. Compared with the case of sealing with a sealing material for coating or coating with a corrosion-resistant coating means, the cost is low.

(4-2)
In the present embodiment, the contact portion accommodation spaces S2, S3 are adjacent to the discharge portion accommodation space S5.

  Thus, even if the contact portion accommodating spaces S2, S3 and the discharge portion accommodating space S5 are adjacent to each other, the air flow passes through the contact portion accommodating spaces S2, S3 to the discharge portion accommodating space S5. Since it flows, it can suppress that the product (active species) produced | generated in the discharge part 152 flows into contact part accommodation space S2, S3.

(4-3)
In the present embodiment, in the contact state of the insertion contact portions 52a and 52b, a gap at the time of insertion exists between the insertion openings 46a and 46b and the insertion contact portions 52a and 52b.

  In the present embodiment, even if there is a location where air circulation occurs such as a gap during insertion, the air flow flows through the contact portion accommodating spaces S2 and S3 to the discharge portion accommodating space S5. It can suppress that the product (active species) produced | generated by this flows into contact part accommodation space S2, S3. Moreover, since it is not necessary to seal the above gaps using a separate member, cost can be suppressed.

(4-4)
In the present embodiment, a part of the air flow (blowout flow) blown out from the blowout port 12 flows to the main body attachment unit 30 as the divided flow A1. That is, the air flowing into the contact portion accommodating spaces S <b> 2 and S <b> 3 is air purified inside the main body 10. Therefore, it is possible to suppress the adhesion of the fixed contact portions 47a and 47b, the insertion contact portions 52a and 52b, and the surrounding dust. Thereby, tracking can be suppressed.

(4-5)
Moreover, in this embodiment, the atmospheric | air pressure of contact part accommodation space S2, S3 is higher than the atmospheric | air pressure of discharge part accommodation space S5.

  In the present embodiment, the contact portion accommodating spaces S2 and S3 are in communication with the intake port 43, so that an air flow can easily flow into the contact portion accommodating spaces S2 and S3.

  Here, the air pressure (reverse flow) flowing from the discharge part accommodation space S5 to the contact part accommodation spaces S2 and S3 can be suppressed because the pressure in the contact part accommodation spaces S2 and S3 is higher than the atmospheric pressure in the discharge part accommodation space S5. . Therefore, corrosion of the fixed contact portions 47a and 47b and the insertion contact portions 52a and 52b can be suppressed.

(5) Modifications While the embodiment of the present invention has been described with reference to the drawings, the specific configuration is not limited to the above-described embodiment, and can be changed without departing from the gist of the invention. .

(5-1) Modification 1A
FIG. 6 is an exploded perspective view of the main body mounting unit 30 according to Modification 1A.

  In addition to the above embodiment, the flow dividing guide 44 may be provided with a flow dividing member 44a. The flow dividing member 44 a has a flat plate shape and is provided to extend upward from the flow dividing guide portion 44. The split flow forming member 44a has a function of regulating the flow of the split flow A1. Therefore, in such a configuration, the diversion A1c flowing to the discharge unit 50 can be reduced as in the above embodiment, so that more air can be guided to the contact portion accommodating spaces S2 and S3 than in the above embodiment. it can.

  Thereby, the atmospheric | air pressure difference of contact part accommodation space S2, S3 and discharge part accommodation space S5 can be enlarged further than the said embodiment.

  The diversion guide portion 44 may be configured to be integrally formed with the diversion forming member 44a.

(5-2) Modification 1B
In the said embodiment, the contact point electrically connected is formed by taking the contact state in which the insertion contact part 52a, 52b is inserted in insertion opening 46a, 46b and contacts the fixed contact part 47a, 47b. However, the present invention is not limited to this, and a contact (part) for supplying a voltage to the discharge part 152 in the contact part accommodating space may be formed in advance.

(5-3) Modification 1C
In the said embodiment, although demonstrated only to the floor-standing type air conditioner which has an air purifying function, it is not restricted to this. For example, it may be applied to an air conditioner that further has a humidifying function or a dehumidifying function, a ceiling-mounted air conditioner that is embedded or suspended in the ceiling, or a wall that is embedded or attached to a wall. You may apply to an attachment type air conditioner.

  The present invention is applicable to various air conditioners that perform discharge in which a product having a strong oxidizing power is generated.
