Description

  The present invention relates to a blower.

  Conventionally, the interior of a vehicle such as a passenger car or the interior of a building is a sealed space, so odors and allergen substances are trapped in the sealed space, and walls, curtains, dashboards, seats, etc. in the space There is a problem of sticking to the interior of the. For this reason, various types of filtration-type air purification apparatuses are provided, but odorous components and allergen substances adhering to the interior cannot be removed.

  In view of this, an electrostatic atomizer that generates nanometer-sized charged fine particle water (nanomist) by atomizing water has attracted attention. The nanometer-sized charged fine particle water generated by this electrostatic atomizer contains radicals such as superoxide radicals and hydroxy radicals, and is effective in deodorizing, eradicating and suppressing viruses and molds, and inactivating allergen substances. In recent years, it has attracted attention because of its effects. For this reason, it is possible to deodorize odorous components adhering to indoor walls, sheets, dashboards, curtains, etc., and to suppress allergen substances such as pollen brought into the room adhering to people and clothes. it can.

  Patent Document 1 is known as one in which charged fine particle water generated by such an electrostatic atomizer is blown into a room. Patent document 1 arrange | positions in the ventilation path of the air conditioner provided in the vehicle, exposes a discharge electrode to a part of air flow which flows through the inside of a ventilation path, and applies a high voltage to the water supplied to the front-end | tip of a discharge electrode. Then, the water is electrostatically atomized to generate charged fine particle water, and this charged fine particle water is carried on an air stream flowing along the discharge electrode, and blown out from the outlet into the vehicle interior.

  However, in the conventional example shown in Patent Document 1, the charged fine particle water generated by electrostatic atomization of the water supplied to the tip of the discharge electrode flows in the air passage along the discharge electrode. Since it is put on the air flow and blows out from the outlet directly into the interior of the vehicle, the small amount of water supplied to the tip of the discharge electrode is exposed to the air flow that flows in the air passage along the discharge electrode, and the water is exposed There is a risk that it will be blown away by the air flow without being electrostatically atomized, and a stable tailor cone may not be generated. As a result, stable electrostatic atomization cannot be achieved, and stable charged fine particle water is generated and ejected into the room. There is a problem that it cannot be done.

  Therefore, the present inventor arranges the electrostatic atomizer outside the air passage, generates charged fine particle water with the electrostatic atomizer without being affected by the air flow flowing through the air passage, and It was considered that the charged fine particle water generated in the above was sent into the air passage and was blown into the room from the outlet through the air flow flowing in the air passage.

  However, in addition to the vehicle air conditioners described above, in the central heating system that controls the air conditioning of the entire building, the air pressure flowing through the air passage is pressurized by the blower fan, so the air pressure flowing through the air passage is large. The pressure is higher than atmospheric pressure. For this reason, the charged fine particle water produced | generated with the electrostatic atomizer cannot be sent in the ventilation path used as a high voltage | pressure only by making an electrostatic atomizer communicate with a ventilation path. For this reason, it is conceivable to provide a dedicated charged fine particle water feed fan for sending charged fine particle water into the air blowing path in the electrostatic atomizer. However, the charged fine particle water delivery fan has a smaller capacity than the blower fan, so that most of the air flow path is at a higher pressure than the electrostatic atomizer and can still feed charged fine particle water into the blower path. Can not. Here, when there is a location where the pressure is low in the air passage, it is conceivable to connect the electrostatic atomizer to a part of the air passage where the pressure is low.

  However, in this case, communication connection can be made only to a very limited low pressure part in the air passage, and there is a great restriction on the connection position of the electrostatic atomizer to the air passage, so the communication connection position is free. There is a problem that you cannot choose.

  Moreover, in the air conditioner and the central heating system, the operation of the blower fan is switched in order to adjust the amount of air conditioning in the room. Under the same conditions that the flowing air pressure changes, the charged fine particle water cannot be fed into the air flow flowing through the air passage, and the charged fine particle water feed becomes unstable. Further, when the operation of the blower fan is maximized, the air pressure flowing through the blower passage becomes the highest, and in such a case, it becomes more difficult to feed charged fine particle water into the airflow flowing through the blower passage. .

Further, in the fixed air inlet, it is difficult to take in from the air inlet depending on the direction of the air flowing through the air passage and the mounting position of the electrostatic atomizer.
JP 2006-151046 A

  The present invention was invented in view of the above-described conventional problems, and even when the mounting position of the electrostatic atomizer is different and the direction of the air flow is changed, the charged fine particle water is stably discharged into the air. It is an object of the present invention to provide a blower that can be used.

  In order to solve the above problems, a blower according to the present invention includes a discharge electrode 1, an electrostatic atomization chamber 2 in which the discharge electrode 1 is disposed, a water supply means 3 for supplying the tip of the discharge electrode 1, and a discharge device. Forming an electrostatic atomizer 5 having a high voltage applying means 37 for generating charged fine particle water by applying a high voltage to the water at the tip of the electrode 1 for electrostatic atomization; Charged particulate water generated in the electrostatic atomization chamber 2 of the electrostatic atomizer 5 in the air passage 10 having the air blowing fan 6 having the suction port 7 in the part and the air outlet 8 in the downstream end. Is an air blower A that discharges air from the air outlet 8, and includes an inlet portion 12 that takes in part of the air flowing through the air passage 10 into the electrostatic atomization chamber 2, and electrostatic mist from the inlet portion 12. And an outlet portion 13 for discharging the entire amount of air taken into the chemical conversion chamber 2 to the blower passage 10, and at least the inlet portion 12 is The electrostatic atomizer 5 is attached to the air passage 10 or an attachment member different from the air passage 10 so as to be located in the air passage 10, and the flow direction of the air flow flowing through the air passage 10 to the inlet portion 12 An air flow collision wall 4 is formed for taking air from the inlet 12 into the electrostatic atomization chamber 2 in a state where the pressure is increased by collision of the air flow flowing through the air flow path 10 protruding in the intersecting direction. The discharge air pressure discharged from the outlet portion 13 into the air passage 10 is set to be larger than the air pressure near the outlet portion 13 in the air passage 10, and the inlet portion 12 is in a certain direction in the above-mentioned crossing direction. The electrostatic atomizer 5 is attached to an attachment member different from the air passage 10 or the air passage 10 so that the inlet portion 12 and the outlet portion 13 are opened in the air passage 10. In the state, the air flow of the plurality of inlet portions 12 flows. It is characterized in that formed by closing the remainder of the inlet portion 12 with closure means 43 except the inlet portion 12 located upstream of the direction that.

  By adopting such a configuration, the pressure of the air pressure that the discharge air pressure discharged from the outlet portion 13 of the electrostatic atomizing chamber 2 into the air passage 10 is larger than the air pressure near the outlet portion 13 in the air passage 10. By utilizing the difference, the charged fine particle water generated in the electrostatic atomizing chamber 2 can be smoothly fed into the air flowing through the air passage 10 that has been pressurized by the air blowing fan 6 and has become high pressure. In this case, the inlet 12 that takes in part of the air flowing through the air passage 10 into the electrostatic atomization chamber 2 and the entire amount of air that is taken into the electrostatic atomization chamber 2 from the inlet 12 is discharged to the air passage 10. And an outlet portion 13 for projecting in the direction intersecting the flow direction of the airflow flowing through the air passage 10 at the inlet portion 12 and the airflow flowing through the air passage 10 collides with the airflow collision wall portion 4. Since the air is taken into the electrostatic atomization chamber 2 from the inlet portion 12 in a state where the pressure is increased, the discharge air pressure discharged from the outlet portion 13 can be changed to the air passage with a simple configuration. Since the air in the electrostatic atomization chamber 2 can flow from the outlet 13 into the air passage 10 due to the pressure difference as described above, the air pressure in the vicinity of the outlet 13 in the air 10 can be increased. Electrostatic atomization for fast air flow in the channel The charged fine particle water is sent out on a slow flow due to the pressure difference without being exposed to the exposed portion, and the water supplied to the tip of the discharge electrode 1 is blown away by the air flow flowing in the air passage 10. It is possible to discharge the charged fine particle water into the high-pressure air passage 10 stably and surely by electrostatic atomization, and anywhere in the air passage 10, The charged fine particle water can be fed into the air passage 10 as described above. Further, even if the air pressure in the air passage 10 is changed by adjusting the blower fan 6, the charged fine particle water is blown as described above. It can be fed into the road 10.

  In addition, a plurality of the inlet portions 12 are provided at different positions around one axis in the intersecting direction, and the electrostatic atomizer 5 is connected to the air passage 10 or the air passage so that at least the inlet portion 12 is located in the air passage 10. In the state where it is attached to an attachment member different from 10, the remaining inlet portions 12 other than the inlet portion 12 located on the upstream side in the air flow direction among the plurality of inlet portions 12 are closed by the closing means 43. Therefore, when only one inlet portion 12 is provided, the inlet portion 12 may be attached so as to cross and face the air flow flowing in the air passage 10 due to restrictions when the electrostatic atomizer 5 is attached. However, in the present invention, among the plurality of inlet portions 12 provided in the circumferential direction, the other inlet portions 12 are closed except for the inlet portions 12 facing the air flow flowing in the air passage 10. By electrostatic atomizer Of different mounting orientation, even if the orientation of the blower is changed, it becomes a stable charged water particles can be released into the air.

  The housing 40 of the electrostatic atomizer 5 is provided with a plurality of inlet portions 12 at different positions around one axis in a direction intersecting the flow direction of the air flow, and the cap member 41 is placed in the housing 40 in the flow direction. The cap member 41 is provided with a closing means 43 and the cap member 41 is attached to the housing 40 in the direction in which the air flow flows in the plurality of inlet portions 12. It is preferable to close the remaining inlet portions 12 except the inlet portion 12 located on the upstream side by the closing means 43.

  With such a configuration, by adjusting the mounting position of the cap member 41 to the housing 40 around the axis in the direction intersecting the flow direction, one inlet portion 12 of the plurality of inlet portions 12 can be easily obtained. Can be communicated with one inlet 12 located upstream in the direction of air flow, and the remaining inlet 12 can be closed.

  The charged fine particle water sent into the high-pressure air passage 10 in this way rides on the air flow flowing in the air passage 10 and blows out from the outlet 8 into the room 11, floats in the room 11, and moves into the room. It adheres to the interior of 11 walls, curtains, dashboards, seats, etc. and the clothes of people in the room 11 and is accumulated in various places and clothes in the room 11 by charged nanometer-sized water containing radicals. It is possible to effectively decompose or suppress odorous components and allergen substances.

  Since the present invention is configured as described above, the charged fine particle water can be generated stably by electrostatic atomization without being affected by the flow of air flowing in the air passage. Water can be stably and reliably sent into the air passage using the pressure difference between the discharge air pressure discharged from the outlet portion into the air passage and the air pressure near the outlet portion in the air passage. In order to take air from the inlet into the electrostatic atomization chamber in a state where the pressure is increased by the air flow flowing through the air flow path colliding with the flow direction of the air flow flowing through the air flow path at the part By forming the airflow collision wall portion, a pressure difference between the discharge air pressure discharged from the outlet portion into the air passage and the air pressure near the outlet portion in the air passage can be provided with a simple configuration. In addition, even if the direction of the air flow changes, it becomes possible to stably discharge the charged fine particle water into the air, and even when there are restrictions on the installation direction when mounting the electrostatic atomizer, Even if the direction is changed, the above-mentioned effect can be reliably achieved by positioning the inlet portion provided with the air flow collision wall portion on the upstream side in the air flow direction.

  The electrostatic atomizer 5 having the above-described configuration is, for example, as shown in FIGS. 1, 2, and 3, at an arbitrary position of the air passage 10, in the embodiment, between the heat exchanger 9 and the air outlet 8 of the air passage 10. The electrostatic atomizing chamber 2 is attached so as to communicate with an arbitrary position.

  When the electrostatic atomizer 5 is attached, the electrostatic atomizer 5 is attached to the outer surface portion of the air passage 10 or attached to an attachment member different from the air passage 10.

  In this case, the mounting portions 40d (40d1, 40d2) provided on both side portions of the housing main body 40a are mounted with screws or the like, but arbitrary positions of the heat exchanger 9 and the outlet 8 of the air passage 10 A mounting portion 40d (mounting portion 40d1, mounting portion 40d2) is formed in a state in which a hole portion 29 is provided in the opening portion 29 and the cap member 41 is fitted into the hole portion 29 so that the inlet portion 12 is not closed. ) Is attached to an outer surface portion of the air passage 10 or an attachment member different from the air passage 10.

  In this case, depending on the position of the air passage 10 where the hole 29 is provided, the housing 40 may not be attached unless the direction in which the housing 40 is attached to the air passage 10 is changed.

  For example, when the hole 29 is provided near the air outlet 8 as shown in FIG. 1, the hole 29 cannot be attached unless the attachment portion 40 d 1 is positioned closer to the air outlet 8. Further, when the hole 29 is provided in the vicinity of the corner portion of the air passage 10 as shown in FIGS. 2 and 3, the hole cannot be attached unless the attachment 40 d 1 is positioned closer to the corner portion.

  The examples shown in FIGS. 1 and 3 and the example shown in FIG. 2 differ in the direction in which the housing 40 is attached to the air passage 10 with respect to the flow of air flowing through the air passage 10 by 180 °. In this way, even if the mounting direction of the housing 40 to the air passage 10 is different, the remaining inlet portions 12 are blocked by leaving the inlet portion 12 at a position facing the direction in which the airflow flows among the plurality of inlet portions 12. By attaching the cap member 41 so as to be closed at 43, even if the mounting direction of the housing 40 changes, one inlet 12 can be positioned on the upstream side in the direction in which the airflow flowing through the air passage 10 flows, Further, the air flow collision wall portion 4 corresponding to the inlet portion 12 can be arranged in a state of projecting into the air blowing path 10 and can be positioned so as to cross and face the air flow.

  Further, the outlet portion 13 is positioned on the downstream side of the air flow path 10 with respect to the air flow collision wall portion 4. Further, the projecting direction of the air flow collision wall portion 4 into the air passage 10 and the opening direction of the inlet portion 12 intersect the air flow direction i in the portion of the air passage 10 where the electrostatic atomizer 5 is mounted. It is a direction (in the embodiment, a direction intersecting at a right angle).

  In the example in which the electrostatic atomizer 5 is provided in the air conditioner Aa provided in the vehicle, the high voltage applying means 37 for applying a high voltage to the water supplied to the tip of the discharge electrode 1 is mounted on the vehicle, for example. A certain battery may be used.

  The air conditioner Aa operates the blower fan 6 and the heat exchanger 9 to pressurize the air sucked from the suction port 7 by the blower fan 6 and blow the air in the blower passage 10. It cools or heats by 9 and blows off into the room | chamber 11 from the blower outlet 8 as cold wind or warm air.

  When the electrostatic atomizer 5 is operated, the Peltier unit 16 that is the cooling means 17 is energized to cool the cooling unit 21, and the cooling unit 21 is cooled to cool the discharge electrode 1. Water in the inside is condensed to supply water (condensed water) to the tip of the discharge electrode 1. When a high voltage is applied to the water supplied to the tip of the discharge electrode 1 in a state where water is supplied to the discharge electrode 1 in this way, the level of the water supplied to the tip of the discharge electrode 1 by the high voltage. Is locally raised in a cone shape (tailor cone). When the tailor cone is formed in this way, 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 like this and the charge concentrates on 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 (repulsive force of the charge that has become dense). In response, the nanometer-sized charged fine particle water charged negatively by repeating splitting and scattering (Rayleigh splitting) exceeding the surface tension is generated in a large amount in the electrostatic atomization chamber 2.

  Here, since the air flowing through the blower passage 10 is pressurized by the blower fan, the pressure P1 of the air flowing through the blower passage 10 is higher than the atmospheric pressure. On the other hand, the pressure P2 of air introduced into the electrostatic atomization chamber 2 from the inlet 12 is such that the protruding direction of the air flow collision wall 4 and the opening direction of the inlet 12 are the above-described electrostatic atomization of the air passage 10. Since the air flow direction a intersects with the air flow direction a at the portion where the device 5 is mounted, the air flow collision wall 4 collides with a part of the air flow that is pressurized in the air passage 10 and flows. Is increased (becomes pressure P2) and is introduced into the electrostatic atomization chamber 2 from the inlet portion 12, and the inside of the electrostatic atomization chamber 2 becomes pressure P2. Therefore, in the electrostatic atomization chamber 2 and the outlet 13 portion of the air passage 10, the air pressure in the electrostatic atomization chamber 2 is P2, and the air pressure in the air passage 10 is P1, and there is a pressure difference between them. Has occurred. Here, since P2> P1, air is sent from the electrostatic atomization chamber 2 into the air passage 10 due to the difference in air pressure, and thereby charged fine particle water generated in the electrostatic atomization chamber 2. However, it is sent into the air passage 10 along the air flow due to the difference in air pressure. Therefore, the pressure P2 of the air in the electrostatic atomizing chamber 2 becomes the discharge air pressure from the electrostatic atomizing chamber 2 into the air passage 10.

  As described above, since the pressure difference causes the air to flow from the outlet portion 13 into the air passage 10, the air flowing through the electrostatic atomization chamber 2 is a slow flow unlike the fast flow flowing through the air passage 10. The charged fine particle water is sent out on the slow flow caused by the pressure difference without exposing the portion where the electrostatic atomization is performed to the fast air flow flowing through the air passage 10. The water supplied to the tip is not blown away by the air flow flowing through the air passage 10, and the inside of the air passage 10 in which the charged fine particle water has a high pressure by stably electrostatically atomizing. Can be sent out.

  As described above, the air in the electrostatic atomization chamber 2 flows from the outlet portion 13 into the air passage 10 due to the pressure difference. At this time, the amount of air sent from the outlet portion 13 to the air passage 10 and the air flow The amount of air that collides with the collision wall 4 and is increased in pressure to be taken into the electrostatic atomization chamber 2 is the same. That is, the air taken into the electrostatic atomization chamber 2 from the inlet portion 12 is discharged only from the outlet portion 13, and as a result, all the air taken in from the inlet portion 12 is blown from the outlet portion 13. Will be returned to the road 10.

  In addition, since the electrostatic atomizer 5 can be attached anywhere in the air passage 10 as described above, the charged fine particle water is fed into the air passage 10 as described above anywhere in the air passage 10. Furthermore, even if the air blower 6 is adjusted to change the air pressure in the air passage 10, the charged fine particle water can be sent into the air passage 10 as described above.

  The charged fine particle water sent into the air passage 10 is sent to the air outlet 8 along the air flow flowing through the air passage 10, and blown out from the air outlet 8 into the room 11. And float on the wall, seat, dashboard, curtain, etc. of the room 11.

  Nanometer-sized charged fine particle water (nanomist) generated by atomizing water contains radicals such as superoxide radicals and hydroxy radicals, and therefore adhered to the walls, sheets, dashboards, curtains, etc. of the room 11 The odor component can be deodorized, and allergen substances such as pollen that are brought into the room by adhering to a person or clothes can be suppressed, and sterilization and sterilization can be performed. Moreover, since it is as small as a nanometer size, it floats to every corner of the room 11, and it can penetrate into the inside of the fiber or the like to deodorize, sterilize, sterilize, suppress allergen substances, and the like.

  In addition, as shown in an accompanying drawing, the inside of the air flow path 10 is enclosed by enclosing 3 sides except the inlet part 12 side of the wall part 4 for an airflow collision with the portal-type rib comprised with a pair of rib 55 and the cover rib 56. The air flow can be guided so that a part of the flowing air flow can effectively collide with the air flow collision wall 4.

  In the embodiment shown in the attached drawings, an example is shown in which two inlet portions 12 are provided 180 degrees apart about one axis in the intersecting direction, but three or more inlet portions 12 may be provided at equal intervals around the axis. .

  Further, the cap member 41 may be rotatably attached to the cylindrical portion 40c, so that the cap member 41 can be attached in a manner that the mounting position in the circumferential direction can be changed around the axial center of the cylindrical cylindrical portion 40c.

  In the above-described embodiment, the air conditioner Aa provided in a vehicle such as an automobile is described as the blower A. However, as the blower A, a central heating type air conditioner that controls the air conditioning of the entire building in the building, or other air conditioner. It may be.

  Moreover, as the air blower A, it is not limited only to the air conditioner Aa provided with the heat exchanger 9, The air blower Ab which performs only ventilation like FIG. 3 without the heat exchanger 9 may be sufficient.
