  A blower with a discharge device according to an embodiment of the present invention includes a blower passage having a blower outlet for releasing air, and a discharge device disposed outside the blower passage, having a means for generating an active ingredient. I have. Further, the blower with a discharge device includes an introduction pipe having one end connected to the discharge device and the other end arranged in the blower passage to guide the active component into the blower passage.

  In addition, the air outlet has a plurality of openings that are at least partially defined by a partition wall in a front view of the air outlet, and an opening surface is formed at the other end of the introduction pipe. ing.

  Further, the other end side of the introduction pipe is arranged along the air flow in the air passage, and the opening surface is arranged in the vicinity of the upstream side of the partition wall.

  And the said opening surface is arrange | positioned in one opening part of these opening parts by the front view of the said blower outlet.

  If it carries out like this, it can suppress that the flow of the air in the ventilation path which flows the circumference | surroundings of an inlet tube will be inhibited by the partition wall. As a result, the air flow in the air passage easily flows around the introduction pipe, and the air in the introduction pipe is easily attracted to the air passage. Therefore, the active ingredient can be introduced into the air passage more efficiently.

  Moreover, the said opening surface can be arrange | positioned in the center of one opening part of these opening parts by the front view of the said blower outlet.

  If it carries out like this, it will become possible to suppress more reliably that the flow of the air in the ventilation path which flows the circumference | surroundings of an inlet tube will be inhibited by a partition wall.

  Further, the front surface of the air outlet in a state where the air direction adjusting plate is adjusted so that the air direction of the air discharged from the air outlet is in a direction perpendicular to the air outlet surface of the air outlet, the opening surface is the plurality of air holes. It is also possible to arrange it at the center of one of the openings.

  If it carries out like this, it will become possible to enlarge the movable range of the wind direction adjusting plate which can suppress that the flow of the air in an air flow path is inhibited by the wind direction adjusting plate as much as possible. For this reason, the influence of the air flow in the air passage on the change of the position of the wind direction adjusting plate can be minimized.

  Further, the introduction pipe may have an inclined portion whose outer diameter increases from the opening side toward the one end side.

  By doing so, the outer diameter is increased on the side connected to the discharge device, so that the active component generated in the discharge device can be more reliably guided into the introduction tube. In addition, since the outer diameter is small on the opening side, it is possible to suppress as much as possible that the air flow in the air passage is obstructed by the partition wall (wind direction adjusting plate).

  And the air taken in in the air-conditioning part 220 passes the filter 22, and the foreign material in air is removed. Thereafter, the air from which the foreign matter has been removed is introduced into the evaporator 23 and the temperature is adjusted.

  Then, the air whose temperature has been adjusted by the evaporator 23 (adjusted air) is introduced into the blower passage 260 and discharged from the respective outlets 212 into the vehicle compartment 3. In the present embodiment, the adjusted air is introduced from the air conditioning unit 220 into the air passage main body 270, passes through the air passage main body 270, and is introduced into each branch passage 280 branched into a plurality of branches. Then, the air introduced into each branch passage 280 (adjusted air) is discharged into the vehicle compartment 3 from the air outlet 212 formed on the downstream side through each branch passage 280.

  Further, in the present embodiment, a finisher 24 is attached to each air outlet 212. The finisher 24 is formed in a frame shape from a synthetic resin or the like, and is attached to the downstream end (the outlet 212) of the branch pipe 250.

  In addition, although what can adjust the direction (wind direction) of the wind blown in the vehicle interior 3 from the blower outlet 212 only to the left-right direction is illustrated in FIG. 3, it is not restricted to this. For example, by allowing the partition wall 25b extending in the horizontal direction to rotate about a rotation axis extending substantially vertically, the direction of the wind blown into the passenger compartment 3 from the outlet 212 (wind direction) ) Can be adjusted vertically and horizontally. It is also possible to adjust the direction (wind direction) of the wind blown into the passenger compartment 3 from the air outlet 212 only in the vertical direction.

  Next, an electrostatic atomizer (discharge device) 30 that generates charged fine particle water 40 will be described with reference to FIG.

  As shown in FIG. 4, the electrostatic atomizer 30 according to the present embodiment includes a discharge unit 310 having a discharge electrode (first electrode) 311, a Peltier unit (liquid) having a cooling unit 330 and a heat dissipation unit 340. Supply section) 320.

  Further, the discharge electrode 311 is connected to the cooling unit 330 side of the Peltier unit 320 so as to be freely cooled. In addition, by supporting the counter electrode (second electrode) 312 at the tip of the support frame 350 connected to the Peltier unit 320, the discharge electrode 311 and the counter electrode 312 are positioned to face each other at a predetermined interval. It is fixed. The counter electrode 312 is not essential, and can be omitted if a high voltage at which discharge occurs is applied to the discharge electrode 311. Moreover, you may make it make an electrification removal board oppose other than the housing in which the electrostatic atomizer 30 is stored.

  The cooling unit 330 includes an insulating plate 331 made of alumina or aluminum nitride having high thermal conductivity, and a cooling insulating plate 332 having high thermal conductivity and high electric resistance made of alumina, aluminum nitride, or the like. A circuit 331a is formed on one side of the insulating plate 331 (the lower side in FIG. 4).

  On the other hand, the heat radiating section 340 includes an insulating plate 341 made of alumina or aluminum nitride having high heat conductivity, and a high heat conductive heat radiating plate 342 made of metal such as aluminum. A circuit 341a is formed on one side of the insulating plate 341 (upper side in FIG. 4), and a plurality of radiating fins 342a are formed on one side (lower side in FIG. 4) of the heat radiating plate 342. .

  Further, BiTe thermoelectric elements 360 arranged in a large number are arranged between the circuits 331a and 341a facing each other so as to face each other. Adjacent thermoelectric elements 360 are electrically connected by circuits 331a and 341a on both sides. In this way, when the thermoelectric element 360 is energized via the Peltier input lead wire 370, heat is transferred from one side of the cooling unit 330 and the heat radiation unit 340 to the other side.

  In this embodiment, as described above, the cooling unit 330 is formed by the cooling-side insulating plate 331 and the cooling insulating plate 332, and the heat-dissipating unit 340 is formed by the heat-dissipating-side insulating plate 341 and the heat-dissipating plate 342. ing. Then, heat is transferred from the cooling unit 330 side to the heat radiating unit 340 side via the thermoelectric element 360.

  In the present embodiment, the support frame 350 is formed in a cylindrical shape with both ends penetrating using an insulating material such as PBT resin, polycarbonate, or PPS resin. A flange portion 352 for connection is projected from the outer peripheral edge of the opening on one end side of the support frame 350 over the entire circumference, and the opening on the other end (hereinafter referred to as mist discharge port 312a). ) Is provided with a ring-shaped counter electrode 312 integrally formed by insert molding or the like. A plurality of screw holes 352a are provided in the flange portion 352 at equal intervals in the circumferential direction, and the flange portion 352 is screwed to the peripheral portion of the heat dissipation plate 342 with screws 353 through the screw holes 352a. The support frame 350 is connected to the Peltier unit 320. The connecting means is not limited to screwing. For example, it is possible to bond both the 350 and 320 while pressing the support frame 350 against the Peltier unit 320.

  Further, a partition wall 351 extending from the inner peripheral surface of the support frame 350 to divide the inner space into a discharge space S1 and a sealing space S2 is extended. A communication hole 351a for communicating both the spaces S1 and S2 is formed in the center of the partition wall 351.

  The discharge electrode 311 is formed using a material having high thermal conductivity and conductivity such as aluminum, copper, tungsten, titanium, and stainless steel, and the main portion 311a is formed in a columnar shape. Further, a sharp discharge portion 311b is formed at the distal end of the main portion 311a, and a sandwiched portion 311c having a diameter larger than that of the main portion 311a is formed at the proximal end side. When the support frame 350 is connected to the Peltier unit 320, the main body portion 311a of the discharge electrode 311 is fitted into the communication hole 351a, and the discharge portion 311b side is positioned in the discharge space S1, and the sandwiched portion 311c side. Is positioned in the sealing space S <b> 2, so that the partition wall 351 of the support frame 350 sandwiches the sandwiched portion 311 c of the discharge electrode 311 and the cooling insulating plate 332 of the Peltier unit 320. By this sandwiching, the discharge electrode 311 is pressed toward the cooling unit 330 side of the Peltier unit 320 to be in a connected state.

  That is, the support frame 350 functions as a clamping member that sandwiches the cooling unit 320 and the discharge electrode 311 in order to fix the cooling unit 330 and the discharge electrode 311 of the Peltier unit 320 in a connected state. It also functions as a sealing member that holds the circuits 331a and 341a and the thermoelectric element 360 in 320 in a sealed state in which moisture does not enter.

  Reference numeral 390 denotes a sealing resin made of an epoxy resin, which makes the inside of the Peltier unit 320 more securely sealed. The sealing resin 390 is not limited to be disposed between the support frame 350 and the cooling insulating plate 332 or between the support frame 350 and the discharge electrode 331 as illustrated. The inside of the unit 320 may be filled.

  Reference numeral 381 denotes a metal or conductive material such that one end side is connected to the discharge electrode 311 in the discharge space S1 of the support frame 350 and the other end side is drawn out of the support frame 350 and connected to the high voltage application unit 380. Is a high-voltage lead wire formed using a functional plastic. A high voltage applying unit 380 electrically connected to the discharge electrode 311 via the high-voltage lead 381 is further electrically connected to the counter electrode 312, so that a high voltage is applied between the electrodes 311 and 312. It has become so.

  In the electrostatic atomizer 30 having the above-described configuration, when energization is performed via the Peltier input lead wire 370 to the thermoelectric element 360 in a sealed state by the connection of the support frame 350 and the heat radiating plate 342, the inside of each thermoelectric element 360 The heat transfer occurs in the same direction in FIG. 3, and the discharge electrode 311 is cooled via the cooling unit 330 connected to the cooling side of the heat transfer, and the air around the discharge electrode 311 in the discharge space S <b> 1 of the support frame 350. Is cooled. As a result, moisture in the air is liquefied by condensation or the like, and water is generated on the surface of the discharge electrode 311.

  Then, in a state where water is generated and held particularly in the discharge part 311b of the discharge electrode 311, the discharge voltage 311 is such that the discharge part 311b side of the discharge electrode 311 becomes a negative electrode by the high voltage application part 380 so that charges are concentrated. A high voltage is applied between the electrode 312 and the counter electrode 312. Thereby, the water held in the discharge part 311b receives large energy and repeats Rayleigh splitting, and a large amount of nanometer-sized charged fine particle water 40 can be generated. The charged fine particle water 40 moves toward the counter electrode 312 that faces the discharge electrode 311, passes through the mist discharge port 312 a, and is discharged to the outside of the electrostatic atomizer 30.

  The charged fine particle water 40 generated by the electrostatic atomizer 30 contains radicals such as superoxide radicals and hydroxy radicals, and thus has a deodorizing effect, a virus / mold fungus suppressing effect, an allele substance inactivating effect, etc. There is. For example, if the charged fine particle water 40 is sent out into the passenger compartment, not only the odorous components in the air in the passenger compartment but also the odorous components adhering to the wall surfaces and sheets in the passenger compartment can be deodorized. Furthermore, it is possible to suppress allergens such as pollen that have been brought into the passenger compartment and adhered to human clothes.

  Although the electrostatic atomizer has been described as an example of the discharge device, the liquid supply unit is omitted, and an ion generator that generates air ions such as negative ions and / or positive ions instead of charged fine particle water is used. You can also. This ion generator can also generate hydroxy radicals, and can achieve substantially the same effect as the electrostatic atomizer 30 described above.

  In the present embodiment, air discharged into the vehicle compartment 3 from the outlet 212 of at least one branch passage 280 out of the plurality of branch passages 280 using the electrostatic atomizer 30 described above is electrostatically charged. The charged fine particle water 40 generated by the atomizer 30 is included.

  At this time, the electrostatic atomizer 30 is disposed in the branch passage 280, and the charged fine particle water 40 generated by the electrostatic atomizer 30 is placed on the air flow R1 in the branch passage 280, whereby the charged fine particle water 40 is obtained. Can be diffused in the passenger compartment 3.

  However, when the electrostatic atomizer 30 is disposed in the air passage 260 of the vehicle air conditioner 20 including devices such as the evaporator 23 and the blower 21, the air (high-temperature air and / or low temperature) adjusted by the air-conditioning unit 220 is arranged. The electrostatic atomizer 30 is exposed to air with humidity. Thus, when the electrostatic atomizer 30 is exposed to the adjusted air (high temperature air and / or low humidity air), the water supplied to the discharge electrode 311 for electrostatic atomization. May evaporate due to conditioned air. As a result, electrostatic atomization due to discharge may be inhibited.

  In particular, in the electrostatic atomizer 30 shown in the present embodiment, the discharge electrode 311 is cooled so that moisture in the air is condensed to generate water for electrostatic atomization on the discharge electrode 311. I have to. This type of electrostatic atomizer 30 has excellent usability in that it does not require the trouble of replenishing water. However, when it is exposed to adjusted air, condensed water is discharged onto the discharge electrode. It may become impossible to generate.

  Therefore, in the present embodiment, the electrostatic atomizer 30 is disposed outside the air passage 260, and the electrostatic atomizer 30 is exposed to high-temperature air or low-humidity air flowing in the air passage 260. It is possible to suppress this. In this way, the charged fine particle water 40 can be generated in the electrostatic atomizer 30 without being affected by the air flowing in the air passage 260.

  Then, one end 51 is connected to the electrostatic atomizer 30 and the other end 52 is generated in the electrostatic atomizer 30 via the introduction pipe 50 arranged in the branch path 280 (the air duct 260). The charged fine particle water 40 is guided into the branch path 280. This introduction pipe 50 can also be formed using resin, for example.

  In the present embodiment, as shown in FIG. 6, the introduction pipe 50 enters the branch passage 280 (the air passage 260) in the vicinity of the air outlet 212 in the branch passage 280 (the air passage 260). And the site | part which has entered in the branched path 280 (air supply path 260) of the introduction pipe 50 is arrange | positioned so that the air flow R1 which flows through the inside of the branched path 280 (air supply path 260) may be followed. Further, the opening surface 50 a is positioned in the vicinity of the upstream side of the partition wall 25.

  By the way, if the inner surface of the introduction pipe 50 is uneven or there is a portion bent at a right angle in the middle of the introduction pipe 50, a turbulent flow occurs in the flow of the charged fine particle water 40 in the introduction pipe 50, and the introduction pipe 50 The amount of charged fine particle water 40 discharged from the 50 opening surfaces 50a may be greatly reduced. Therefore, it is preferable to make the inner surface of the introduction pipe 50 smooth.

  Further, if the length of the introduction pipe 50 is longer than 50 cm, the charged fine particle water 40 may be reduced in the middle, and therefore the length of the introduction pipe 50 is preferably 50 cm or less.

  The other end 52 side of such an introduction pipe 50 can be made to enter the branch path 280 (air blowing path 260), for example, by a method as shown in FIG.

  Specifically, an opening 291 is provided in the middle of the branch path 280 (blower path 260). The lid 290 that closes the opening 291 is provided with a penetrating portion that allows the introduction tube 50 to pass therethrough and a holding rib 292 that holds the distal end side (the other end 52 side) of the introduction tube 50. Then, when the leading end side (the other end 52 side) of the introduction pipe 50 is penetrated through the penetrating portion and is held by the holding rib 292, the opening 291 is closed by the lid 290, so that the branch path of the introduction pipe 50 is obtained. The part which has entered in 280 (blower channel 260) will be arranged along the air flow R1 which flows in the branch channel 280 (blower channel 260).

  At this time, the introduction pipe 50 is held by the lid 290 in a state in which a straight line or a smooth curve is drawn between both ends.

  Here, in the present embodiment, the charged fine particle water 40 generated by the electrostatic atomizer 30 can be more efficiently introduced into the branch path 280.

  Specifically, the other end 52 side of the introduction pipe 50 is arranged along the air flow R1 flowing in the branch passage 280 (the air blowing path 260), and the opening surface 50a is formed on the partition wall 25 (the wind direction adjusting plate 25a). It is located in the vicinity of the upstream side.

  Furthermore, the opening surface 50a is arranged in one opening 212a among the plurality of openings 212a in a front view of the air outlet 212 (see FIG. 3).

  Moreover, in this Embodiment, the opening surface 50a is arrange | positioned in the center of one opening part 212a of the some opening parts 212a by the front view of the blower outlet 212. FIG.

  In the present embodiment, the partition wall 25 has a turnable wind direction adjusting plate 25a. Then, the front surface of the air outlet 212 in a state in which the air direction adjusting plate 25a is adjusted so that the air direction of the air discharged from the air outlet 212 is orthogonal to the opening surface of the air outlet 212, the opening surface 50a has a plurality of It arrange | positions at the center of one opening part 212a of the opening parts 212a. That is, the opening surface 50a is arranged at the center of the opening 212a in a state where the side surface of the air direction adjusting plate 25a is aligned with the air flow R1 flowing in the branch passage 280 (the air blowing passage 260).

  Furthermore, in the present embodiment, the introduction pipe 50 has an inclined portion 53 whose outer diameter increases from the opening 50a side toward the one end 51 side.

  The outer diameter of the introduction pipe 50 is preferably 12 mm or less. By so doing, when the introduction pipe 50 is provided in the branch path 280 (the air passage 260), it is possible to suppress the loss of the air volume flowing through the branch path 280 (the air path 260) by the introduction pipe 50. Will be able to.

  Further, on the one end 51 side of the introduction pipe 50, the inner diameter is about 10 mm so that the charged fine particle water 40 generated by the electrostatic atomizer 30 can be more reliably guided into the introduction pipe 50. It is preferable to do this.

  When the partition wall 25 has a rotatable air direction adjusting plate 25a, the air direction adjusting plate 25a is inclined when the conditioned air is directed in the vertical direction or the left and right direction, so that the area of the opening 212a (front view of the air outlet 212) Therefore, the area of the portion communicating with the air passage 260 is reduced. Therefore, it is preferable to reduce the inner diameter of the introduction pipe 50 on the side of the opening surface 50a so that the opening surface 50a can be prevented from overlapping the wind direction adjusting plate 25a when viewed from the front. However, if the inner diameter of the introduction pipe 50 on the opening surface 50a side is too small, it becomes difficult to introduce the air in the introduction pipe 50 into the branch path 280 (air blowing path 260). Therefore, it is preferable that the inner diameter is about 3 mm on the opening surface 50 a side of the introduction pipe 50.

  With this configuration, when the blower 21 is energized to generate an air flow, the air outside the vehicle compartment 3 or inside the vehicle compartment 3 is taken into the air conditioning unit 220 from the suction port 211.

  And the air taken in in the air-conditioning part 220 passes the filter 22, and the foreign material in air is removed. Thereafter, the air from which the foreign matter has been removed is introduced into the evaporator 23 and the temperature is adjusted.

  Then, the air whose temperature has been adjusted by the evaporator 23 (adjusted air having viscosity) is introduced into the air passage main body 270 from the air conditioning unit 220 and branched into a plurality through the air passage main body 270. It is introduced into each branch 280. Then, the air introduced into each branch passage 280 is discharged into the passenger compartment 3 from the air outlet 212 formed on the downstream side through each branch passage 280.

  At this time, in the present embodiment, the other end 52 side of the introduction pipe 50 is arranged along the air flow R1 flowing in the branch passage 280 (the air blowing path 260), and the opening surface 50a is arranged on the partition wall 25 (wind direction). It is located in the vicinity of the upstream side of the adjusting plate 25a).

  Furthermore, the opening surface 50a is arranged in one opening 212a of the plurality of openings 212a in a front view of the air outlet 212. That is, the distal end side (opening surface 50 a side) of the introduction pipe 50 is disposed in the opening 212 a that does not overlap the partition wall 25.

  The opening 212a in the vicinity of the partition wall 25 is a region where air resistance that hinders the flow of air flowing through the branch passage 280 (the air blowing passage 260) is relatively small. Therefore, if the distal end side (opening surface 50a side) of the introduction pipe 50 is arranged at such a site, more flow toward the opening 212a can be generated around the introduction pipe 50, The air in the introduction pipe 50 is attracted into the branch path 280 by the flow. Therefore, the charged fine particle water 40 generated by the electrostatic atomizer 30 flows into the branch path 280 more efficiently.

  By doing so, the air containing the charged fine particle water 40 in the introduction pipe 50 merges with the air flowing through the branch path 280, and the adjusted air containing the charged fine particle water 40 is sent to the wind direction installed at the outlet 212. It passes through the adjustment plate 25a and is diffused outside the vehicle air conditioner 20, that is, into the passenger compartment 3.

  In the present embodiment, the one in which the electrostatic atomizer 30 and the introduction pipe 50 are arranged on one branch path 280 of the plurality of branch paths 280 is illustrated, but the present invention is not limited to this. Absent. For example, the electrostatic atomizer 30 and the introduction pipe 50 may be arranged in each of the plurality of branch paths 280 so that the adjusted air containing the charged fine particle water 40 is discharged from each outlet 212. Is possible.

  In this way, since the charged fine particle water 40 generated by the electrostatic atomizer 30 can be discharged from the plurality of outlets 212, the effect of the charged fine particle water 40 can be obtained in a short time. .

  As described above, the blower 10 with the discharge device according to the present embodiment has the branch path 280 (the blow path 260) having the air outlet 212 for releasing air and the means for generating the charged fine particle water 40. And an electrostatic atomizer (discharge device) 30 arranged outside the air passage 260. Further, the blower with discharge device 10 has one end 51 connected to the electrostatic atomizer (discharge device) 30 and the other end arranged in the air passage 260 so that the charged fine particle water 40 is placed in the branch passage 280. An introduction pipe 50 is provided.

  Further, the air outlet 212 is formed with a plurality of openings 212a at least partially defined by the partition wall 25 in the front view of the air outlet 212, and the other end 52 of the introduction pipe 50 is open. A surface 50a is formed.

  Further, the other end side of the introduction pipe 50 is arranged along the air flow R <b> 1 in the air blowing path 260, and the opening surface 50 a is arranged in the vicinity of the upstream side of the partition wall 25.

  And the opening surface 50a is arrange | positioned in one opening part 212a of the some opening parts 212a by the front view of the blower outlet 212. FIG.

  If it carries out like this, it can suppress that the flow of the air in the ventilation path 260 which flows the circumference | surroundings of the introductory pipe 50 will be inhibited by the partition wall 25. FIG. As a result, the air flow R <b> 1 in the air duct 260 easily flows around the introduction pipe 50, and the air in the introduction pipe 50 is easily attracted into the air duct 260. Therefore, the charged fine particle water 40 can be introduced into the air blowing path 260 more efficiently.

  Thus, according to the blower 10 with the discharge device according to the present embodiment, the charged fine particle water 40 generated by the electrostatic atomizer (discharge device) 30 is more efficiently transferred into the branch path 280. It can be made to flow.

  Further, as in the present embodiment, the introduction pipe 50 is extended so that the tip portion is close to the blowout port 212, and the position where the negative pressure is likely to be generated at the blowout port 212, that is, the position where it does not overlap with the partition wall 25. If the opening surface 50a of the introduction pipe 50 is disposed at the center, the charged fine particle water can be attracted using negative pressure and sent out from the outlet 212. Therefore, it is possible to eliminate the need to provide a blowing means for forcibly sending the charged fine particle water 40 in the electrostatic atomizer (discharge device) 30 itself.

  Of course, it is also possible to add a blowing means such as a fan to the electrostatic atomizer (discharge device) 30 itself with respect to the present embodiment.

  However, there is a possibility that vibrations or abnormal noises may be generated due to the additional air blowing means, the apparatus may be increased in size, and the cost may be increased.

  On the other hand, if the blower means of the electrostatic atomizer (discharge device) 30 itself is omitted, the possibility of occurrence of vibrations and abnormal noise caused by the blower means can be reduced. An increase in size and an increase in cost can be suppressed.

  Moreover, in this Embodiment, the opening surface 50a is arrange | positioned in the center of one opening part 212a of the some opening parts 212a by the front view of the blower outlet 212. FIG.

  If it carries out like this, it will become possible to suppress more reliably that the flow of the air in the ventilation path 260 which flows the circumference | surroundings of the introductory pipe 50 will be inhibited by the partition wall 25. FIG.

  In the present embodiment, a wind direction adjusting plate 25 a that adjusts the wind direction of the air discharged from the air outlet 212 is arranged in the air blowing path 260. And the partition wall 25 has the wind direction adjustment board 25a.

  In this way, even in the blower 10 with the discharge device capable of adjusting the wind direction, the flow of air in the air passage 260 flowing around the introduction pipe 50 is inhibited by the partition wall 25 (wind direction adjusting plate 25a). Can be suppressed.

  Further, in the present embodiment, when the wind direction adjusting plate 25a is adjusted so that the wind direction of the air discharged from the air outlet 212 is perpendicular to the opening surface of the air outlet 212, the air outlet 212 is opened in front view. The surface 50a is disposed at the center of one opening 212a of the plurality of openings 212a.

  In this way, as shown in FIG. 7, the movable range of the wind direction adjusting plate 25a capable of suppressing the air flow in the air passage 260 from being obstructed by the wind direction adjusting plate 25a can be increased as much as possible. become able to. 7 illustrates the wind direction adjusting plate 25a rotated at the center, but as shown in FIG. 8, the wind direction adjusting plate 25a may be rotated downstream. As shown in FIG. 9, the same effect can be obtained even if the wind direction adjusting plate 25a is rotated on the downstream side.

  As described above, the air in the air passage 260 can be suppressed by enlarging the movable range of the air direction adjusting plate 25a that can prevent the air flow in the air passage 260 from being obstructed by the air direction adjusting plate 25a. Can be minimized as much as possible by the change in the position of the wind direction adjusting plate 25a.

  Further, in the present embodiment, the introduction pipe 50 has the inclined portion 53 whose outer diameter increases from the opening 50a side toward the one end 51 side.

  In this way, the outer diameter is increased on the side connected to the electrostatic atomizer (discharge device) 30, so the charged fine particle water 40 generated in the electrostatic atomizer (discharge device) 30 is more reliably introduced. It can be led into the tube 50. Further, since the outer diameter is reduced on the opening 50a side, it is possible to suppress as much as possible that the air flow in the air passage 260 is obstructed by the partition wall 25 (wind direction adjusting plate 255a).

  Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made.

  For example, in the above-described embodiment, the apparatus in which the electrostatic atomizer is attached to the vehicle air conditioner is illustrated as the blower with the discharge device, but the electrostatic atomizer is installed in the blower other than the vehicle air conditioner. It can also be attached. For example, an electrostatic atomizer can be attached to a blower in a field such as a consumer or a house. It is also possible to attach a discharge device other than the electrostatic atomizer to a blower in the field of consumer, in-vehicle, home, or the like. In addition, a conventionally well-known thing can be used as an air blower or a discharge device.

  In addition, the specifications (shape, size, layout, etc.) of the introduction pipe, the air passage, and other details can be changed as appropriate.

  ADVANTAGE OF THE INVENTION According to this invention, an air blower with a discharge device which can introduce an active ingredient into a ventilation path more efficiently can be obtained.
