Description

  The present invention relates to a blower provided with a discharge device comprising an electrostatic atomizer that generates charged fine particle water by electrostatic atomization or an ion generator that generates ions.

  Conventionally, nanometer-sized charged fine particle water generated by an electrostatic atomizer is placed on an air flow blown from a blower outlet of a blower such as an in-vehicle air conditioner, or in a vehicle room such as an automobile or a building It is known to discharge into the interior chamber.

  Nanometer-sized charged fine particle water released into the room contains radicals such as superoxide radicals and hydroxy radicals, and can deodorize odorous components attached to indoor walls, sheets, dashboards, curtains, etc. It can suppress allergen substances such as pollen brought into the room by adhering to a person or clothes, and can also moisturize skin and hair.

  By the way, in order to discharge the charged fine particle water generated by the electrostatic atomizer onto the air flow of the air blower into the room, for example, the electrostatic atomizer is disposed in the duct of the air blower, It is conceivable to generate charged fine particle water and place the charged fine particle water on the air flow flowing in the duct. However, since the electrostatic atomizer is arranged in the duct, When generating charged fine particle water, there is a problem that the charged fine particle water cannot be stably generated due to the influence of the temperature and humidity of the air flowing in the duct, and the electrostatic atomizer is installed inside the duct. Therefore, there is a problem that the electrostatic atomizing device is complicated to be installed in the duct, and that the electrostatic atomizing device is difficult to maintain and inspect.

  Therefore, it has been proposed to dispose an electrostatic atomizer outside the duct and discharge charged fine particle water generated outside the duct into the duct of the blower. However, during the use of the blower, wind always flows in the duct, and the duct is often positive. And when the inside of a duct is a positive pressure state, the air in a duct flows backward to the electrostatic atomizer side, and it cannot discharge | release charged fine particle water in a duct. Accordingly, there is a problem that the charged fine particle water can be discharged into the duct only at a specific portion where the negative pressure is generated in the duct.

  In addition, an introduction pipe for flowing charged fine particle water is led out from the electrostatic atomizer arranged outside the duct, the introduction pipe is introduced into the duct through a hole provided in the wall of the duct, and the tip of the introduction pipe is connected to the duct. Patent Document 1 proposes that the air flow is prevented from flowing back to the electrostatic atomizer side due to a pressure difference by opening near the air outlet.

  However, in Patent Document 1, it is necessary to provide a hole in the duct, insert the introduction pipe through the hole, and introduce the leading end of the inserted introduction pipe to the vicinity of the duct outlet. In this case, there is a problem that the introduction pipe crosses the inside of the duct at an angle, thereby lowering the original blowing function of the blower, and the work of assembling the introduction pipe into the duct is also troublesome. In addition, since the introduction pipe is inserted by directly making a hole in the duct, there is a problem that if the seal accuracy is not good, the air flow flowing in the duct leaks out from the part where the seal at the edge of the hole is defective. As a result, the original function of the blower is degraded.

  Further, as another conventional example, an electrostatic atomizer is disposed outside the duct, and the introduction pipe connected to the electrostatic atomizer is positioned outside the duct without introducing the introduction pipe into the duct. Patent Document 2 proposes that the leading end of the introduction pipe is opened near the duct outlet.

  In this case, since the entire introduction pipe exists outside the duct, the size of the part including the duct and the introduction pipe becomes large, and the whole apparatus becomes large. End up.

  The present invention has been invented in view of the problems of the above-described conventional example, and without directly opening a hole in the portion of the duct where the air flow is flowing, any position of the inner ridge portion along the duct. The charged fine particle water and ions are supplied from the outlet through the passage while supplying the charged fine particle water and ions through the passage to prevent the air flow flowing through the duct from flowing back to the discharge device side. It is an object of the present invention to provide an air blower equipped with a discharge device that can be discharged in a flow, and the passage for flowing charged fine particle water or ions does not protrude greatly outside the duct, and the overall device can be made compact. .

  In order to solve the above problems, the present invention has the following configuration.

  The present invention is an air blower 3 provided with an electrostatic atomizer 1 that generates charged fine particle water by electrostatic atomization or a discharge device 2 that includes an ion generator that generates ions. A feature of the present invention is that the air blower 3 is provided with a duct 7 having a suction port 4 at an upstream end and a blower outlet 5 at a downstream end and having a blower fan 6, and a wall portion 9 of the duct 7. A part of the inner ridge 8 is protruded into the duct 7, and an inner ridge 8 is formed integrally with the wall 9 of the duct 7 along the duct 7 and the tip of the duct 7 near the outlet 5. A passage 10 having a tip opened near the outlet 5 of the duct 7 is provided in the portion 8, and charged fine particle water or ions generated by the discharge device 2 are discharged into the passage 10.

  With such a configuration, the charged fine particle water or ions generated in the discharge device 2 are passed through the passage 10 provided in the inner ridge portion 8 formed integrally with the wall portion 10 of the duct 7 of the blower device 3. The charged fine particle water or ions can be discharged into the interior of a vehicle such as an automobile or the interior of a building by being discharged in the vicinity of the outlet 5 of the duct 7 and being put on the air flow blown out from the outlet 5. Therefore, unlike the conventional example, it is not necessary to directly make a hole in the portion of the duct 7 where the air flow is flowing and insert the introduction pipe into the duct 7. It becomes possible to supply charged fine particle water and ions through the passage 10 at the position. Further, since the passage 10 is provided in the inner ridge portion 8 formed by protruding a part of the wall portion 9 into the duct 7, the charged fine particle water or ions generated by the discharge device 2 can be supplied to the vicinity of the outlet 5. All or a part of the supply passage 10 is located in the duct 7, and the entire apparatus can be made compact.

  In addition, it is preferable that a hole 11 that opens at the front end surface of the inner ridge portion 8 is formed in the inner ridge portion 8, and the hole 11 serves as a passage 10.

  Thus, by forming a part of the wall portion 9 of the duct 7 integrally as the inner ridge portion 8 having the holes 11, the passage 10 can be formed in the duct 7 itself, the configuration is simplified, and the number of members is reduced. Less. Further, by connecting a discharge hole 36 of the discharge device 2 at an arbitrary position in a portion corresponding to the outer surface of the inner ridge portion 8 on the outer surface of the duct 7, an arbitrary length in the longitudinal direction of the duct 7 can be obtained. The charged fine particle water or ions can be supplied into the passage 10 from the position, and the arrangement position of the discharge device 2 with respect to the duct 7 is not limited.

  Also, the outer surface side of the inner ridge portion 8 is recessed along the inner ridge portion 8 to form an outer surface side ridge portion 12, and the outer surface side ridge portion 12 is separated from the wall portion 9 of the duct 7. It is preferable to arrange a tube body 13 in which the inside of the tube becomes a passage 10.

  Thereby, the pipe body 13 which comprises the channel | path 10 can be made into a different body from the duct 7, and it reaches from the arbitrary positions of the outer surface side groove part 12 to the front-end | tip of the outer surface side groove part 12 according to the arrangement position of the discharge device 2. Thus, the tubular body 13 can be arranged, and the arrangement position of the discharge device 2 with respect to the duct 7 is not limited. Further, the separate tube body 13 is disposed in the outer surface-side recessed portion 12 in which the outer surface side of the inner protrusion portion 8 is recessed along the inner protrusion portion 8. All or part of the duct 7 can be prevented from projecting outside from the outer surface of the duct 7, and the entire apparatus can be made compact.

  Moreover, it is preferable that the inner protrusion 8 includes a portion that becomes a corner in a cross section perpendicular to the air flow direction of the duct 7.

  When a substantially intermediate portion in the width direction of the wall portion 9 on one side of the duct 7 is integrally protruded into the duct 7 to form the inner ridge portion 8, both side surfaces of the inner ridge portion 8 and the inner ridge portion are formed. A gap is generated between each side end of the wall 9 projecting from the wall 8 and the other adjacent wall 9, so that the air flow flowing in the duct 7 is divided by the inner rib 8 and blown Although the air flow is likely to be turbulent at the outlet 5 portion, if the inner ridge portion 8 includes a corner portion in a cross section perpendicular to the air flow direction of the duct 7, the air flow becomes the inner ridge portion. 8 is difficult to be diverted, and air flow turbulence at the outlet 5 can be suppressed.

  Further, a movable louver 15 is provided to face the outlet 5 of the duct 7 and the discharge port 14 at the tip of the passage 10 that opens near the outlet 5, and the movable louver is provided at a portion of the movable louver 15 that faces the discharge port 14. It is preferable to provide a discharge opening 16 that communicates with the discharge port 14 even when the 15 is closed.

  With such a configuration, even when the movable louver 15 is closed or close to being closed, the charged fine particle water or ions discharged from the discharge port 14 at the tip of the passage 10 passes through the discharge opening 16 and the automobile. It can be discharged into the interior of the vehicle or the interior of the building.

  Since the present invention is configured as described above, it is not necessary to make a hole directly in the portion where the air flow of the duct flows and insert a separate introduction pipe into the duct as in the prior art. The charged fine particle water and ions are supplied while supplying the charged fine particle water and ions through the passage at any position of the inner ridge along the line, preventing the air flow flowing through the duct from flowing back to the discharge device side. It can be discharged on the air stream blown from the outlet. In addition, the entire apparatus can be made compact without the passage through which charged fine particle water and ions flow out to the outside of the duct.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  In the accompanying drawings, an example of an air conditioner 3a provided in a vehicle such as an automobile is shown as the blower 3 of the present invention, and an example of the electrostatic atomizer 1 is shown as a discharge device 2 provided in the blower 3. is there.

  In the air conditioner 3a, as shown in FIGS. 1 and 2, the upstream end becomes a suction port 4 for sucking outdoor air or air in the room (inside the car) 11, and the downstream end is A duct 7 serving as an outlet 5 for blowing out air that has been sucked and conditioned into the vehicle interior 18, a blower fan 6 disposed in the duct 7, and a heat exchanger 19 for air conditioning are provided.

  The heat exchanger 19 provided in the air conditioner 3a is for cooling or heating the air blown by the blower fan 6, and in the embodiment, as the heat exchanger 19, for example, an evaporator and a heater Is used.

  A part of the wall portion 9 of the duct 7 is protruded into the duct 7, and an inner ridge portion 8 that extends along the longitudinal direction of the duct 7 (air flow direction) and whose tip reaches the vicinity of the air outlet 5 of the duct 7 is provided. It is formed integrally with the wall portion 9 of the duct 7.

  A passage 10 having a tip opened near the outlet 5 of the duct 7 is provided in the inner ridge 8.

  In the embodiment shown in FIGS. 1 and 2, the embodiment shown in FIG. 5, the embodiment shown in FIG. 6, and the embodiment shown in FIG. 7, the inner ridge portion 8 extends along the longitudinal direction of the inner ridge portion 8. The example which formed the hole 11 and comprised the channel | path 10 by this hole 11 is shown, and the hole 11 used as this channel | path 10 opens to the front end surface of the inner side protrusion part 8, and the back end is obstruct | occluded. The hole 11 is not in communication with the portion of the duct 7 through which air flows.

  When the inner ridge portion 8 is formed by projecting a part of the wall portion 9 of the duct 7 into the duct 7, an arbitrary shape can be considered as the shape of the inner ridge portion 8.

  In the embodiment shown in FIG. 5, a substantially intermediate portion in the width direction of the wall portion 9 constituting one side of the duct 7 is protruded into the duct 7 to form the inner ridge portion 8. In the embodiment shown in FIG. 7, the inner ridge 8 is an example including a corner portion in a cross section perpendicular to the air flow direction of the duct 7. Of these, in the embodiment shown in FIG. The inner ridge 8 includes a portion that becomes two corners in a cross section perpendicular to the air flow direction of the duct 7.

  Here, as shown in FIG. 5, when the inner ridge portion 8 is formed by integrally projecting a substantially intermediate portion in the width direction of the wall portion 9 on one side of the duct 7 into the duct 7, A gap 20 is formed between both side surfaces and both side ends of the wall portion 9 projecting the inner ridge portion 8 and the other wall portions 9 adjacent to each other. There is a possibility that the air flow is likely to be turbulent at the outlet 5 portion because the air flow is diverted to both sides by the ridge portion 8, but the inner ridge portion 8 is connected to the air in the duct 7 as shown in FIGS. If a portion that becomes a corner is included in the cross section perpendicular to the flow direction, the air flow is hardly diverted by the inner ridge portion 8, and the turbulence of the air flow at the blowout port 5 portion can be suppressed, which is more preferable. Of course, the cross-sectional shape of the duct 7 and the cross-sectional shape of the inner ridge portion 8 are not limited to the above-described examples, and various shapes can be employed.

  The electrostatic atomizing apparatus 1 is as shown in FIG. 3 and is attached to the duct 7 or other member constituting the duct 7 by being arranged outside the duct 7 and is a so-called external attachment.

  An electrostatic atomizer main body 22 as shown in FIG. 4 is housed in a housing 21 that constitutes the outline of the electrostatic atomizer 1. The electrostatic atomizer main body 22 shown in FIG. 4 includes a discharge electrode 23, an electrostatic atomization chamber 30 in which the discharge electrode 23 is disposed, water supply means 25 that supplies the tip of the discharge electrode 23, and the discharge electrode 23. And a high voltage applying means 26 for generating charged fine particle water by electrostatic atomization by applying a high voltage to the water supplied to the water. In the embodiment shown in the accompanying drawings, the water supply means 25 is a Peltier device. Water is supplied to the discharge electrode 23 by cooling the moisture in the air with a cooling means such as the unit 27 to generate condensed water. Therefore, in this embodiment, the cooling means constitutes the water supply means 25 that supplies water to the discharge electrode 23.

  Further, in the embodiment shown in the accompanying drawings, the interior of the substantially cylindrical main body case 28 having an insulating property is partitioned by a partition 29, and a Peltier unit which is a water supply means 25 in one half of the partition formed by the partition in the body case 28. 27 and the other half in the main body case 28 is an electrostatic atomizing chamber 30.

  The Peltier unit 27 has a pair of Peltier circuit boards in which a circuit is formed on one side of an insulating plate made of alumina or aluminum nitride having high thermal conductivity, facing each other so that the circuits face each other, and arranged in multiple rows. A BiTe-based thermoelectric element is sandwiched between both Peltier circuit boards, and adjacent thermoelectric elements are electrically connected by circuits on both sides, and one Peltier is energized by energization of the thermoelectric element through a Peltier input lead wire. The heat is transferred from the circuit board side toward the other Peltier circuit board side. A cooling part 31 is connected to the outside of the Peltier circuit board on the one side, and a heat radiating part 32 is connected to the outside of the Peltier circuit board on the other side. As an example, a radiation fin is shown.

  The rear end portion of the discharge electrode 23 is connected to the cooling unit 31 side of the Peltier unit 27, and the discharge electrode 23 is inserted into a hole provided in the partition 29 in the main body case 28 to enter the electrostatic atomization chamber 30. Protruding.

  In the embodiment shown in FIG. 4, an annular counter electrode 33 is provided at the tip opening of a cylindrical main body case 28. Note that the counter electrode 33 may not be provided.

  Openings that open inward and outward are provided at a plurality of locations in the circumferential direction in a portion of the main body case 28 that is a wall portion around the electrostatic atomization chamber 30.

  The housing 21 is provided with a discharge portion 36 for discharging charged fine particle water generated in the electrostatic atomizer main body 22. In the embodiment shown in the accompanying drawings, the discharge portion 36 has a cylindrical shape and has a rear end portion. Is communicated with the electrostatic atomization chamber 30 via the tip of the main body case 28 (in the embodiment, the central opening 35 of the counter electrode 33).

  As described above, the electrostatic atomizer 1 is disposed outside the duct 7 and attached to the duct 7 or other member constituting the duct 7. Corresponding to the position, a connection hole 40 is formed at a position facing the electrostatic atomizer 1 in the longitudinal direction of the outer surface of the inner ridge 8 having the hole 11 formed integrally with the duct 7. The cylindrical discharge part 36 provided in the electrostatic atomizer 1 is connected to the above.

  Here, since the connection hole 40 is formed on the outer surface of the inner ridge portion 8 having the hole 11 formed integrally with the duct 7, even if the connection hole 40 is formed on the outer surface of the duct 7, the blown air in the duct 7 is not generated. A hole is not made in the flowing portion, and the blown air does not leak from the wall portion 9 of the duct 7.

  Further, the connection hole 40 can be opened at an arbitrary position in the longitudinal direction of the outer surface of the inner protrusion 8 having the hole 11 therein. As a result, the electrostatic fog disposed outside the duct 7 The discharge part 36 can be connected by forming a connection hole 40 at a position close to the atomizing device 1, and the electrostatic atomizing device 1 can be arbitrarily connected along the longitudinal direction outside the duct 7 as shown in FIG. 1 and FIG. 2. It becomes possible to arrange | position in the position of.

  In the embodiment shown in FIG. 6, the outer surface of the inner ridge portion 8 having the hole 11 formed integrally with the duct 7 is thinner than the thickness of the other portion of the wall portion 9 along the longitudinal direction. This is an example in which a plurality of thin portions 41 are formed and the connection holes 40 are formed in the arbitrary thin portions 41 in the longitudinal direction. In this embodiment, the connection holes 40 are formed in the thin portions 41. The discharge hole 36 of the discharge device 2 can be connected by simply forming the connection hole 40 at an arbitrary position in the longitudinal direction.

  In addition, the thin part 41 is good also considering only the site | part corresponding to the outer periphery of the connection hole 40 which should be formed as the thin part 41 continuously or intermittently.

  In the embodiment shown in FIG. 7, a plurality of connection holes 40 are formed along the longitudinal direction on the outer surface of the inner protrusion 8 having the holes 11 formed integrally with the duct. This is an example in which an arbitrary connection hole 40 is selected and a cylindrical discharge portion 36 provided in the electrostatic atomizer 1 is connected, and the other connection hole 40 is closed with a lid 42. The discharge part 36 of the discharge device 2 can be connected to the connection hole 40 at any position.

  When the air conditioner 3 a is operated, the blower fan 6 is operated, and the air outside the vehicle (outside the vehicle) or the air inside the room (inside the vehicle) 18 is sucked into the duct 7 from the suction port 4 and is adjusted to the set temperature by the heat exchanger 19. The air flowing through the duct 7 is blown out from the air outlet 5 into the room (inside the vehicle) 18.

  When the electrostatic atomizer 1 is operated during the operation of the air conditioner 3a, the Peltier unit 27 is energized to cool the cooling unit 31, and the cooling unit 31 is cooled to cool the discharge electrode 23. Water in the air is condensed to supply water (condensed water) to the tip of the discharge electrode 23. By applying a high voltage to the water supplied to the tip of the discharge electrode 23 in a state where water is supplied to the discharge electrode 23 in this way, the water supplied to the tip of the discharge electrode 23 by the high voltage is applied. The liquid surface locally rises in a cone shape (tailor cone). When the tailor cone is formed, electric charges are concentrated on the tip of the tailor cone, the electric field strength at this portion is increased, and the tailor cone is further grown. When the tailor cone grows and the charge concentrates at the tip of the tailor cone and the density of the charge becomes high, the water at the tip of the tailor cone has a large energy (the repulsive force of the charge that has become dense). As a result, nanometer-sized charged fine particle water charged negatively by repeating splitting and scattering (Rayleigh splitting) exceeding the surface tension is generated in large quantities.

  The charged fine particle water generated by the electrostatic atomizer 1 is supplied into the hole 11 which is the passage 10 provided inside the inner ridge 8 integrally formed along the duct 7 through the discharge portion 36. It is discharged from the discharge port 14 at the tip through the hole 11 which is 10.

  The discharge port 14 at the tip of the passage 10 is located near the outlet 5 of the duct 7 (in the embodiment, the tip of the inner ridge 8 reaches the tip of the duct 7, and the tip of the inner ridge 8. Discharge port 14 is opened adjacent to the blowout port 5 at the tip of the duct 7), so that the charged fine particle water is not discharged into the duct 7, and is indicated by an arrow indicated by a broken line in FIGS. 1 and 2. In this manner, the air is discharged out of the duct 7 and is supplied to the room (inside the vehicle) 18 by riding on the air flow indicated by the solid line that is blown out from the air outlet 5. In this case, since the discharge port 14 at the front end of the passage 10 is provided in the vicinity of the blowout port 5 at the front end of the duct 7 as described above, air is forced to flow by the blower fan 6 and becomes positive pressure from the duct 7. The air in the duct 7 does not flow backward in the passage 10 and back to the electrostatic atomizer 1 side, and the charged fine particle water is attracted by the air flow blown out from the outlet 5 and discharged from the outlet 14. It is supplied to the room (inside the vehicle) 18 by riding on the airflow.

  Therefore, the charged fine particle water generated by the electrostatic atomizer 1 passes through the passage 10 without providing a fan for smoothly supplying the charged fine particle water generated in the electrostatic atomizer 1 to the discharge port 14 side. It becomes possible to put on the air flow discharged from the discharge port 14 and discharged from the blower outlet 5.

  Of course, the electrostatic atomizer 1 may be provided with a fan to form a flow for discharging the generated charged fine particle water from the discharge port 14 via the passage 10. The charged fine particle water generated in the electrostatic atomizer 1 is discharged from the discharge port 14 through the synergistic effect of the attractive force generated by the blown air flow and the flow of the fan provided in the electrostatic atomizer 1. 5 can be put on smoothly.

  The nanometer-sized charged fine particle water discharged into the room 18 floats in the room 18 and adheres to the inner wall, sheet, dashboard, curtain, indoor clothes, hair, etc. of the room 18.

  The nanometer-sized charged fine particle water (nanomist) generated by atomizing water contains radicals such as superoxide radicals and hydroxy radicals, so the inner wall of the room 18, the sheet, the dashboard, the curtain, It can deodorize odorous components adhering to people's clothes and hair, etc., and it can also suppress allergen substances such as pollen brought into the room after adhering to people and clothes. Or moisturize the skin and hair. Further, since the charged fine particle water is as small as a nanometer size, it can float to every corner of the room 18 and can penetrate into the inside of the fiber or the like to deodorize, sterilize, disinfect, and suppress allergen substances.

The tube body 13 is fitted into the outer surface side recess 12 so that the discharge port 14 at the tip of the tube body 13 is positioned at the end of the outer surface side recess 12. Here, according to the arrangement position of the electrostatic atomizer 1 with respect to the duct 7, the length of the tube body 13 is set to an arbitrary length, and is fitted and arranged in the outer surface side concave strip portion 12. Thereby, the electrostatic atomizer 1 can be disposed at an arbitrary position along the longitudinal direction outside the duct 7.

  In a state in which the tube body 13 is fitted and arranged in the outer surface side recessed portion 12, the tube body 13 in which the inside becomes the passage 10 does not protrude outward from the outer surface of the duct 7, or even if it protrudes, a part thereof protrudes. Therefore, the entire apparatus can be made compact.

  Further, the tube body 13 is not limited to only the hose connected at the rear end portion to the discharge portion 36 of the electrostatic atomizer 1 as described above, and is different from the duct 7 as shown in FIG. It is constituted by a body tube, and the tube is fitted and disposed in the outer surface side concave portion 12, and a connection hole 43 is formed at an arbitrary position in the longitudinal direction of the outer surface of the tube, and electrostatic fog is formed in the connection hole 34.
