Description

  The present invention relates to a negative ion generator that generates negative ions and discharges them into the air in a room or the like.

2. Description of the Related Art Conventionally, ion generators that generate positive ions and negative ions and discharge them into a room or the like have been proposed. The ion generator includes a discharge ion generator that applies a high voltage to an ionization needle to generate ions from the tip of the needle, and the generated ions are discharged into the room by blowing air from a fan or the like. . It is disclosed that such an ion generator can be applied to an ion wind generator that generates an air flow by the kinetic energy of positive ions as a blowing mechanism that replaces a fan. In addition, in order to provide a relaxing effect and a refreshing effect, a mechanism for diffusing an aromatic substance is also provided in parallel. (For example, Patent Document 1 below)
JP-A-11-265780

  However, in the conventional ion generator, since the discharge ion generator and the air blowing mechanism for dissipating the ions generated from the discharge ion generator into the room are separately provided, the apparatus becomes large in size. Cost is also high. Further, merely generating ions does not produce a visually interesting effect.

  The present invention has been made in view of the circumstances as described above, and can be manufactured at an extremely compact and inexpensive cost by combining the air blowing mechanism and the negative ion generation mechanism, and is also visually interesting. An object of the present invention is to provide a negative ion generator capable of obtaining an effect.

To achieve the above object, the negative ion generator of the present invention includes a discharge electrode tip is arranged toward the downstream of the ion wind generating and a counter electrode which is placed on the downstream side of the discharge electrode ,
The discharge electrode generates an ion wind of negative ions by corona discharge by applying a negative potential,
Further downstream of the counter electrode, a movable effect member that produces visual effects by moving with the generated ionic wind, a storage container that stores a liquid agent for diffusing active ingredients, and an upstream of the discharge electrode A liquid transpiration unit that is disposed on the side or the downstream side to evaporate the active ingredient of the liquid to the atmosphere ;
Arranging the liquid evaporation section upstream of the discharge electrode,
A second discharge electrode having a tip disposed between the discharge electrode and the liquid evaporation portion so as to face the liquid evaporation portion, and a second counter electrode disposed on the tip side of the second discharge electrode are further provided. This is the summary.

That is, the negative ion generator of the present invention applies a negative potential to the discharge electrode to cause corona discharge, generates negative ion wind, and blows the generated negative ions with ion wind. In this way, negative ions are generated and diffused in the room with an ionic wind, so that mental stability and relaxation effect by negative ions can be obtained. In addition, since the discharge electrode and the counter electrode serve as the air blowing mechanism and the negative ion generation mechanism, the apparatus is miniaturized and the cost is reduced. In addition, since a movable effect member that moves with the generated ionic wind to produce a visual effect is provided further downstream than the counter electrode, not only negative ions are generated, but also visually interesting. It is also possible to obtain a certain production effect.
The container further includes a container for storing a liquid agent for diffusing the active ingredient, and a liquid agent transpiration unit that is disposed upstream or downstream of the discharge electrode and evaporates the active ingredient of the liquid agent to the atmosphere. Therefore, the active ingredient that naturally evaporates from the liquid transpiration unit is diffused into the room together with negative ions by the force of the ionic wind, and it provides mental stability and relaxation effect due to the negative ions. Obtainable.
Further, a liquid agent evaporating part is disposed on the upstream side of the discharge electrode, a second discharge electrode having a tip disposed between the discharge electrode and the liquid evaporating part so as to face the liquid agent evaporating part, and the second discharge. Since the electrode further includes a second counter electrode disposed along the flow of the ion wind at the tip end side of the electrode, the ion wind generated by the second discharge electrode and the second counter electrode directly acts on the liquid evaporation portion. Therefore, the active ingredient that naturally evaporates diffuses widely by ionic wind.

  In the present invention, the discharge electrode is formed of a large number of carbon fibers cut to a predetermined length. When an ion wind is generated by corona discharge from the tip of each carbon fiber, a distributed discharge is started from the tip of each carbon fiber. By generating the ionic wind, it is possible to generate an ionic wind with a strong power and a strong torque for moving the movable effect member as compared with the case of using a conventional needle-like discharge electrode. In addition, unlike metal needle-like discharge electrodes, the metal itself does not deteriorate and can stably generate negative ions and ionic wind over a long period of time, greatly improving reliability and life. It will be. In addition, since it becomes a distributed discharge by minute electric power, the generation amount of ozone that causes oxidation and irritating odors in the surrounding area is greatly reduced, and the adverse effect of ozone on the surrounding environment is eliminated.

  In the present invention, when the discharge electrode and the counter electrode are arranged in series along the flow direction of the ion wind, the ion wind is generated from the plurality of sets of discharge electrodes and the counter electrode arranged in series. Therefore, more negative ions can be generated, and an ion wind having a stronger torque for moving the movable effect member can be generated.

  In the present invention, when a plurality of sets of the discharge electrode and the counter electrode are arranged in parallel with respect to the flow direction of the ion wind, the ion wind is generated from the plurality of sets of discharge electrodes and the counter electrode arranged in parallel. Therefore, more negative ions can be generated, and an ion wind having a stronger torque for moving the movable effect member can be generated.

  In the present invention, when a liquid agent electrode for applying a negative potential to the liquid agent in the container is further provided, electrons are emitted to the liquid agent in order to apply a negative potential to the liquid agent. This prevents the liquid agent from being oxidized. Therefore, it is possible to maintain the freshness by delaying the deterioration rate of the liquid agent and to prolong the liquid agent.

  In the present invention, a polarization electrode for dielectrically polarizing the storage container by applying a positive or negative potential while facing the outer wall surface of the storage container, and facing at least the polarization electrode of the storage container. When the portion is formed of a dielectric, the liquid agent is exposed to an electric field by dielectric polarization of the portion formed of the dielectric of the liquid container. As a result, an electric field acts on the electron trajectories of the molecules constituting the liquid agent, and electrons are prevented from jumping out of the molecular electron trajectories. Therefore, oxidation of the liquid agent molecules is prevented, the deterioration rate of the liquid agent is delayed, the freshness is maintained, and the liquid agent can be prolonged.

  In the present invention, the liquid agent transpiration unit includes a liquid surface of the liquid agent stored in a storage container, and the second discharge electrode is applied with a negative potential to blow an ion wind containing negative ions toward the liquid surface. , The negative ions carried by the ionic wind are sprayed directly on the liquid surface of the liquid agent, and electrons are given to the liquid agent to prevent oxidation of the liquid agent. Therefore, it is possible to maintain the freshness by delaying the deterioration rate of the liquid agent and to prolong the liquid agent.

  Next, the best mode for carrying out the present invention will be described.

  1 and 2 are diagrams showing an embodiment of a negative ion generator to which the present invention is applied.

  The negative ion generator is disposed inside the cylindrical frame 18 so as to follow the flow of the ion wind on the downstream side of the discharge electrode 1 with the tip disposed so as to go downstream of the ion wind to be generated. Arranged on the lower side of the discharge electrode 1, the movable effect member 3 that produces a visual effect by moving with the generated ionic wind on the further downstream side of the counter electrode 2. A liquid container 14 is accommodated.

  More specifically, in this example, the discharge electrode 1 is arranged so that the tip thereof faces the upper opening along the longitudinal direction of the cylindrical frame 18, and the cylindrical counter electrode 2 is cylindrical above the discharge electrode 1. It is arranged concentrically with the frame 18. The discharge electrode 1 is located substantially at the center of the counter electrode 2 in plan view. The counter electrode 2 is supported on the cylindrical frame 18 by a support member 28, and the discharge electrode 1 is supported by a support member 29. An air intake 20 is formed on the side surface of the cylindrical frame 18 where the discharge electrode 1 is supported.

  In this state, when a negative potential is applied to the discharge electrode 1 and a positive potential is applied to the counter electrode 2, corona discharge occurs at the tip of the discharge electrode 1, and electrons move from the tip of the discharge electrode 1 toward the inner surface of the counter electrode 2. Is released. The emitted electron flow collides with gas molecules while being accelerated by a high electric field, gives kinetic energy to the gas molecules, and generates air currents as electron-induced wind of air. At this time, some of the electrons are trapped in the outer shell of the gas molecule bond activation and become negatively charged negative ion molecules. Therefore, the electron induction wind becomes an air flow of an ion wind containing negative ion molecules.

  As described above, the ionic wind generated by applying a DC potential to the discharge electrode 1 and the counter electrode 2 becomes an air flow from the bottom to the top in the cylindrical frame 18, and the ionic wind containing negative ion molecules is opened in the upper opening. 19 is discharged into the room and outside air is taken in from the air intake 20.

  On the downstream side of the counter electrode 2, that is, in the vicinity of the upper opening 19 of the cylindrical frame 18, a movable effect member 3 that moves with the generated ionic wind to produce a visual effect is disposed. The movable effect member 3 is attached to the cylindrical frame 18 by a support member 30. In the illustrated example, an example in which a propeller that rotates with an ionic wind of an updraft is applied as the movable effect member 3 is shown. The movable production member 3 is not a seed limited to this, but a visual production effect is obtained by moving in response to an ion wind, such as a fiber, a wind bell, or a doll that is formed in a resin shape with an LED attached to the base. Various types can be applied as long as possible.

  On the other hand, on the upstream side of the discharge electrode 1, in this example, the bottom of the cylindrical frame 18, a storage container 14 for storing a liquid agent 13 for diffusing active ingredients is disposed. Further, an absorbent body such as felt or sponge for sucking and evaporating the liquid agent 13 is disposed so that the lower part is immersed in the liquid agent and the upper part protrudes from the upper opening of the container 14. The protrusion of the absorber functions as a liquid transpiration unit 15 that evaporates the liquid 13 to the atmosphere. The liquid transpiration unit 15 is disposed on the upstream side of the discharge electrode 1, and when the outside air taken in from the air intake 20 becomes an ionic wind and is diffused into the room from the upper opening 19, The active ingredient evaporated is diffused into the room through the upper opening 19.

  As the liquid agent 13, for example, a fragrance can be applied and the fragrance component can be diffused into the room together with the negative ion molecules by ionic wind. The liquid agent 13 is not limited to the fragrance, and for example, various types such as a deodorant, an insect repellent, an insecticide, a repellent and a bactericide can be applied.

  FIG. 2 is a diagram showing details of the discharge electrode 1. The discharge electrode 1 is formed of a large number of carbon fibers 6 cut to a predetermined length, and corona discharge is generated from the tip of each carbon fiber 6 to generate an ion wind.

  In this example, a large number of carbon fibers 6 are bundled and an insulating rubber member 7 formed into an annular shape is viewed, and the outside is caulked with a bundling member 8 of a metal ring, and the root portion is made of metal. The terminal member 9 is wound and configured. The rubber member 7 and the binding member 8 are supported by the support member 29, and a negative potential is applied to the terminal member 9. The bundled carbon fibers 6 have their ends cut in a direction perpendicular to the longitudinal direction X along the air flow to be generated.

  By applying a negative potential to the discharge electrode 1 configured as described above, a corona discharge can be generated from the tip of each carbon fiber 6 to generate a strong ion wind with a weak electric power. In addition, since corona discharge is generated with weak electric power, the amount of ozone generated is drastically reduced.

  As described above, according to the negative ion generator of the present embodiment, a negative potential is applied to the discharge electrode 1 to cause corona discharge to generate a negative ion wind, and the generated negative ions are generated by an ion wind. Blow. In this way, negative ions are generated and diffused in the room with an ionic wind, so that mental stability and relaxation effect by negative ions can be obtained. In addition, since the discharge electrode 1 and the counter electrode 2 serve both as a blowing mechanism and a negative ion generation mechanism, the apparatus is downsized and the cost is reduced. In addition, since the movable effect member 3 is provided further downstream than the counter electrode 2 to produce a visual effect by moving with the generated ionic wind, not only negative ions are generated, but also visually. It is also possible to obtain an interesting production effect.

  Further, the discharge electrode 1 is formed from a large number of carbon fibers 6 cut to a predetermined length, and a corona discharge is generated from the tip of each carbon fiber 6 to generate an ion wind. By generating the ionic wind, it is possible to generate an ionic wind with a strong power and a strong torque for moving the movable effect member 3 as compared with the case where a conventional needle-like discharge electrode is used. In addition, unlike metal needle-like discharge electrodes, the metal itself does not deteriorate and can stably generate negative ions and ionic wind over a long period of time, greatly improving reliability and life. It will be. In addition, since it becomes a distributed discharge by minute electric power, the generation amount of ozone that causes oxidation and irritating odors in the surrounding area is greatly reduced, and the adverse effect of ozone on the surrounding environment is eliminated.

  Moreover, since the container 14 which accommodates the liquid agent for diffusing an active ingredient, and the liquid agent evaporation part 15 which is arrange | positioned in the upstream of the said discharge electrode 1 and evaporates the active ingredient of the said liquid agent with respect to air | atmosphere were further provided. The active ingredient that naturally evaporates from the liquid transpiration unit 15 is diffused into the room together with the negative ions by the force of the ionic wind, and the mental stability and relaxation effect by the negative ions are obtained, and the effect of the active ingredient diffusing into the room is also obtained be able to.

  FIG. 3 is a diagram illustrating a negative ion generator according to the second embodiment of the present invention.

  In this embodiment, a liquid agent transpiration unit 15 is disposed upstream of the discharge electrode 1, and a tip is disposed between the discharge electrode 1 and the liquid agent transpiration unit 15 so as to face the liquid agent transpiration unit 15. It further includes a discharge electrode 23 and a second counter electrode 24 disposed on the distal end side of the second discharge electrode 23.

  More specifically, the second discharge electrode 23 is formed by bundling carbon fibers 6 like the discharge electrode 1, and faces the opposite side of the discharge electrode 1 below the discharge electrode 1. It is arranged with the tip facing down. The second counter electrode 24 is formed in a ring shape in this example, and is disposed concentrically with the cylindrical frame 18, and the second discharge electrode 23 is disposed at a substantially central position in plan view of the second counter electrode 24. ing.

  An air intake 20 is formed on the side surface of the cylindrical frame 18 at a height position where the discharge electrode 1 and the second discharge electrode 23 are disposed, and the active component is dissipated below the second counter electrode 24. The mouth 25 is open.

  A negative potential is applied to the second discharge electrode 23, and a positive potential is applied to the second counter electrode 24. Thereby, the ion wind which blows down from the 2nd discharge electrode 23 to the 2nd counter electrode 24, ie, from the top to the bottom, is generated like the principle mentioned above. Then, the ionic wind generated by the second discharge electrode 23 and the second counter electrode 24 takes in the active component evaporated from the liquid evaporation unit 15 and is diffused to the outside from the effective component discharge port 25, and the outside air from the air intake port 20. Is adopted.

  According to this embodiment, since the ionic wind generated by the second discharge electrode 23 and the second counter electrode 24 directly acts on the liquid agent transpiration unit 15, the effective component that naturally transpirations diffuses widely by the ionic wind. Moreover, since negative ion molecules are also generated by the second discharge electrode 23 and the second counter electrode 24, the mental stability and relaxation effect by the negative ions are doubled.

  In addition, the liquid evaporation part 15 includes the liquid level 16 of the liquid stored in the storage container 14, and a part of the ionic wind blown down directly acts on the liquid level 16. As described above, since the second discharge electrode 23 is applied with a negative potential and an ion wind containing negative ions is blown toward the liquid surface 16, the negative ions carried by the ion wind are directly applied to the liquid surface 16 of the liquid agent 13. When sprayed and given electrons to the liquid 13, the liquid 13 is prevented from being oxidized. Therefore, it is possible to maintain the freshness by delaying the deterioration rate of the liquid agent 13 and make the liquid agent 13 last longer.

  Moreover, in this embodiment, the counter electrode 2 for moving the movable effect member 3 is arranged so that the electrode surface is along the air current of the ion wind, so that the flow of electrons for generating the ion wind is further accelerated, and the mobile effect is generated. The ionic wind for moving the member 3 becomes stronger. On the other hand, since the ionic wind for diffusing the active ingredient may be weaker than the ionic wind for moving the movable effect member 3, the second facing that generates the ionic wind for diffusing the active ingredient of the liquid 13 is used. Since the electrode 24 is formed in a ring shape and the length in the airflow direction is shortened, the size of the apparatus can be reduced by that much, and the equipment efficiency can be improved.

  Other than that, it is the same as that of the said 1st Embodiment, and attaches | subjects the same code | symbol to the same part. Even in this embodiment, the same effects as those of the first embodiment are obtained except for the effects described above.

That is, the set of the discharge electrode 1 and the counter electrode 2 is arranged in two upper and lower stages. In the cylindrical frame 18, air intake ports 20 are formed at respective height positions of the upper and lower discharge electrodes 1.

  In this example, ion winds are respectively generated from the upper and lower discharge electrodes 1 and the counter electrode 2. The ion wind generated at the lower discharge electrode 1 and the counter electrode 2 passes through the upper counter electrode 2. At this time, the ion wind generated at the discharge electrode 1 and the counter electrode 2 generated at the lower stage is further given kinetic energy by the electrons emitted from the discharge electrode 1 at the upper stage, and the ion wind is accelerated. This acts on the movable effect member 3.

  As a result, ion wind is generated from the plurality of sets of discharge electrodes 1 and counter electrodes 2 arranged in series, so that more negative ions are generated and ion wind with stronger torque for moving the movable effect member 3 is generated. Can be generated.

  On the other hand, similarly to the second embodiment, a second discharge electrode 23 and a second counter electrode 24 are arranged below the lower discharge electrode 1 to generate a blown-down ion wind, and a liquid agent transpiration unit. 15 and the active ingredient evaporated from the liquid surface 16 as a part of the liquid agent transpiration part 15 are put on an ionic wind and emitted from the active ingredient diffusion port 25.

  In this aspect, the second discharge electrode 23 and the second counter electrode 24 may be omitted as in the first embodiment. Moreover, although the example which provided the group of the discharge electrode 1 and the counter electrode 2 in two steps was shown in the figure, it is not limited to this and can arrange | position three or more steps.

  Other than that, it is the same as that of the said 1st and 2nd embodiment, and attaches | subjects the same code | symbol to the same part. Even in this embodiment, the same effects as the first and second embodiments are obtained except for the effects described above.

  FIG. 5 is a diagram for explaining a negative ion generator according to a fourth embodiment of the present invention.

  In this embodiment, a plurality of sets of the discharge electrode 1 and the counter electrode 2 are arranged in parallel with respect to the flow direction of the ion wind.

And the rotation center of the propeller as the movable effect member 3 is arrange | positioned so that it may be located in the center of the said equilateral triangle.

  By doing so, an ion wind is generated from the plurality of sets of discharge electrodes 1 and the counter electrode 2 arranged in parallel, so that more negative ions are generated and the torque for moving the movable effect member 3 is increased. A strong ionic wind can be generated.

  The figure shows an example in which three sets of discharge electrodes 1 and counter electrodes 2 are arranged in parallel. However, the present invention is not limited to this, and two sets can be arranged in parallel, and four or more sets can be arranged in parallel. It can also be arranged.

  In this embodiment, a plurality of sets of discharge electrodes 1 and counter electrodes 2 arranged in parallel can be further arranged in series along the direction along the flow of the ion wind. In this case, the number of sets of the discharge electrodes 1 and the counter electrodes 2 arranged above and below can be the same or different. For example, one set of discharge electrode 1 and counter electrode 2 is arranged above and below three sets of discharge electrode 1 and counter electrode 2, or three sets of discharge electrode 1 and counter electrode 2 are similarly set above and below three sets. A pair of discharge electrode 1 and counter electrode 2 can also be arranged.

  In this example, a needle-shaped liquid agent electrode 33 hangs down from the lower end of the discharge electrode 1, and the liquid agent electrode 33 is immersed in the liquid agent 13 so that its tip reaches the bottom surface. A negative potential is applied to the liquid electrode 33 in the same manner as the discharge electrode 1.

  In this way, since a negative potential is applied to the liquid agent 13 in the container 14, the liquid agent 13 is prevented from being oxidized by emitting electrons to the liquid agent 13. Therefore, it is possible to maintain the freshness by delaying the deterioration rate of the liquid agent 13 and make the liquid agent 13 last longer. In particular, when the liquid agent 13 containing a naturally-derived component is used, deterioration due to oxidation of the naturally-derived component is prevented, which is effective in extending the life of the liquid agent 13 itself.

The side in contact with the liquid agent 13 is dielectrically polarized to a negative potential.

  Thus, the liquid agent 13 is exposed to the electric field by dielectrically polarizing the portion of the container 13 formed of the dielectric of the container 14. As a result, an electric field acts on the electron orbits of the molecules constituting the liquid agent 13, and the electrons are prevented from jumping out from the electron orbits of the molecules. Therefore, the oxidation of the liquid agent molecules is prevented, the deterioration rate of the liquid agent 13 is delayed, the freshness is maintained, and the liquid agent 13 can be prolonged. In particular, when the liquid agent 13 containing a naturally-derived component is used, deterioration due to oxidation of the naturally-derived component is prevented, which is effective in extending the life of the liquid agent 13 itself.

  In the illustrated example, a negative potential is applied to the polarization electrode 34, but a positive potential is applied to the polarization electrode 34, so that the bottom of the container 14 made of a ferroelectric material faces the polarization electrode 34. Dielectric polarization may be performed so that the side is negative potential and the side in contact with the liquid agent 13 is positive potential. In this case, the same effect can be obtained. Alternatively, the polarization electrode 34 can be used as one electrode, the other electrode can be grounded, and an alternating current can be applied.
