An ion generating element (10) has at least one first discharger (12) for generating positive ions and at least one second discharger (13) for generating negative ions, both fitted or printed on a single dielectric member (11). The first and second dischargers (12) and (13) are each composed of a pair of a first or second discharging electrode (12a) or (13a), respectively, formed on the surface of the dielectric member (11) and a first or second induction electrode (12b) or (13b), respectively, buried in the dielectric member (11), and are arranged both on the same flat surface of the dielectric member (11) but separately from and independently of each other. This construction helps to alleviate the neutralization among the generated ions themselves, thus to effectively release both positive and negative ions, and thereby to enhance the ion generation efficiency.
Description
Technical Field
The present invention relates to an ion generating element, an ion generating device, and an electric apparatus equipped with the ion generating element and the ion generating device, which can decompose bacteria, fungi, harmful substances, and the like floating in the air by emitting positive ions and negative ions in a space. Examples of the electric devices include air conditioners, dehumidifiers, humidifiers, air purifiers, refrigerators, fan heaters, microwave ovens, washing and drying machines, vacuum cleaners, and sterilizers used in closed spaces (e.g., rooms in home, buildings, hospital wards and operating rooms, vehicles, airplanes, ships, warehouses, and refrigerators).
Background
In general, in a closed room with low ventilation such as an office or a conference room, when the number of people in the room is large, air pollutants such as carbon dioxide discharged by breathing, cigarette smoke, and dust are increased, and negative ions having a relaxing effect are reduced from the air. Particularly, when the smoke of the cigarette exists, the negative ions are even reduced to about 1/2-1/5. Therefore, various ion generators are now commercially available for supplying negative ions in the air.
However, the conventional ion generating device using the discharge phenomenon mainly generates negative ions by a negative potential dc high voltage system, and its purpose is to appeal to the effect of human power. Therefore, in such an ion generating device, although negative ions can be supplied to the air, floating bacteria and the like in the air cannot be removed positively.
As a result of examining the examples of the conventional publications, the following methods have been known for other ion generators.
Japanese patent laying-open No. 4-90428 (hereinafter, referred to as patent document 1) describes an ionizer that generates negative ions or negative and positive ions by applying an ac high voltage to a discharge line or a discharge plate having an acute angle portion. However, only high ac voltage cells are described with respect to the method and apparatus of generation. The application field is air conditioners, and comfort and relaxation to human are given as effects.
In japanese patent laying-open No. 8-217412 (hereinafter, referred to as patent document 2), the following corona discharger is described: the insulator is sandwiched between the discharge electrodes and the inductive electrodes to form a pair of electrodes, and a high-voltage power supply for applying a high-voltage high-frequency voltage to both ends of the pair of electrodes is provided. As the high voltage power source, a power source in which a diode is disposed at both ends of an electrode and a negative potential or a positive potential is selected depending on the direction thereof has been described, but the switching function thereof is not described. Further, as an application field of the present technology, corona discharge devices such as an ozone generator, a charging device, and an ion generator are described. Further, the effect of the present technology is the generation of ions.
Japanese patent application laid-open No. Hei 3-230499 (hereinafter referred to as patent document 3) discloses an ion generator comprising: a plurality of needle-shaped discharge electrodes and a conductive grounding grid or a grounding ring are arranged in a manner of two-dimensionally expanding in a direction crossing a cleaning air flow, a high voltage of an alternating sine wave after negative bias is applied to some discharge electrodes, and a high voltage of an alternating sine wave after positive bias is applied to some discharge electrodes, so that a plurality of groups of discharge electrodes for releasing positive ions and a plurality of groups of discharge electrodes for releasing negative ions are formed. The ion generating device has a control unit for adjusting bias voltage, and adjusts the amounts of positive ions and negative ions. The field of application is a static elimination device for a clean room, and its static elimination effect is described as an effect.
Japanese patent application laid-open No. 9-610 (hereinafter, referred to as patent document 4) discloses a dust collector in which the voltage applied to the electrodes for positive and negative electrode discharge is variable. The electrode is an ionization line and a dust collecting plate, and is a structure for charging dust and collecting the dust on the dust collecting plate. Specifically, an electric dust collector for air conditioners is described as an application field in which the inside of the electric dust collector is sterilized by ozone generated during discharge.
Ion generating electrodes utilizing the discharge phenomenon are roughly classified into 2 types. As disclosed in patent documents 1, 3, and 4, a wire or a metal piece having an acute angle portion, a needle, or the like is used, and the opposite pole is the ground or a metal piece and a mesh to the ground potential are used, and air functions as an insulator. The other is a structure in which a discharge electrode and an induction electrode are formed by sandwiching a solid dielectric therebetween as described in patent document 2 and japanese patent laid-open nos. 2003 and 47651 (hereinafter referred to as patent document 5) and 2002 and 319472 (hereinafter referred to as patent document 6) described later. The former uses air as an insulator, and the distance between electrodes needs to be larger than the latter, so that the voltage required for discharge must be set high. In contrast, since the latter sandwiches an insulator having high insulation resistance and high dielectric constant, the distance between the electrodes can be made narrow (thin), and therefore, the applied voltage can be set lower than the former.
The present invention relates to an ion generator, and more particularly to an ion generator comprising: as an effect of releasing both polar ions of positive ions and negative ions, the ion generating material is used in the airApproximately equal amounts of H as positive ions occur in gas+(H2O)mWith O as negative ion2 -(H2O)n(m and n are natural numbers), and the two ions surround the airborne fungi and viruses, and generate the virusesThe action of the hydroxyl group (. OH) of the formed radical can inactivate the aforementioned fungi, such as plankton fungi (see, for example, patent documents 5 and 6).
Further, in the practical machine which has been put into practical use by the applicant of the present invention, there are an ion generator having a structure in which a discharge electrode is disposed on the outer side and an induction electrode is disposed on the inner side with a dielectric material interposed therebetween, and an air cleaner, an air conditioner, and the like in which the ion generator is mounted.
Further, as the negative ion effect, it is generally known that it is effective when a large amount of negative ions are supplied to a space where there are too many positive ions due to electric equipment in a home or the like, and it is desired to obtain a state where the positive ions and the negative ions are balanced as in a forest in the natural world or to obtain a relaxation effect. The relaxation effect is also taught in patent document 1.
Disclosure of Invention
The purpose of the invention is: positive ions and negative ions are generated to inactivate fungi and viruses floating in the air and to further enhance the effect thereof. In general, an ionizer using a discharge phenomenon generates ozone at the same time as ions are generated, and patent document 4 describes that the inside of the apparatus is sterilized by using the oxidizing ability of ozone. It is generally known that a high concentration of ozone has an influence on the human body, and it is a difficult problem for the applicant of the present invention to extract the maximum amount of ions while minimizing the amount of ozone generated.
Further, in a small-sized ion generating device which can be mounted in a household electric appliance, not the device which is the subject of patent document 3, the present applicant has already proposed the ion generating devices described in patent documents 5 and 6, etc., and if the ion generating device is used, positive ions and negative ions can be generated in substantially the same amount.
In order to reduce the neutralization of the positive ions and the negative ions occurring simultaneously, the ions are generally diffused into the space by the air blowing. However, there is also a problem that, by generating positive ions and negative ions at the same time, part of the generated ions of both polarities is neutralized and then extinguished. The ion generating device described in patent document 3 has a plurality of discharge electrodes arranged so as to extend two-dimensionally in a direction crossing the flow of cleaning air. That is, the wind flows in the direction in which the needle extends. In view of reduction in size, safety, and energy saving, the applicant of the present invention mainly adopts a configuration in which a pair of electrodes is formed by a discharge electrode provided on the surface of a dielectric and an induction electrode embedded inside the dielectric, and in this case, in the direction of wind described in patent document 3, wind blows parallel to the surface of the dielectric due to unsuitability for diffusion of ions. When the ion generator to be developed is mounted on various commercial products, it is effective to limit the direction of wind to the ion generator to an ideal direction, but the direction may not be limited depending on the case.
The present invention has been made in view of the above problems, and an object of the present invention is to provide: provided are an ion generating element, an ion generating device and an electric apparatus equipped with the ion generating device, wherein a strategy for suppressing the neutralization of generated ions with each other and efficiently releasing the ions is studied, and the ion generating efficiency can be further improved.
In order to achieve the above object, an ion generating element according to the present invention includes at least 1 first discharge portion 1 generating positive ions and a second discharge portion 2 generating negative ions, each of which is mounted on or printed on 1 substrate, wherein the first and second discharge portions 1 and 2 are disposed on the same plane of the substrate and are separated from each other and independent of each other on a diagonal line (inclined). The electrode may be a needle-like electrode, but basically, the applicant of the present invention considered a structure in which a pair of electrodes is formed by a discharge electrode provided on the surface of a dielectric and an inductive electrode embedded in the dielectric. In this case, in order to prevent ions generated from the upwind discharge part from being neutralized by the downwind discharge part of opposite polarity even if air is blown to the surface of the discharge electrode on the dielectric from any one direction of the X-axis direction and the Y-axis direction, the 1 st discharge part and the 2 nd discharge part are arranged diagonally, that is, obliquely with respect to the direction of the air blowing (X-axis direction or Y-axis direction), so as to reduce the neutralization.
When the area of the substrate on which the 1 st and 2 nd discharge portions are mounted or printed is limited, it is considered that it is difficult to arrange the 1 st and 2 nd discharge portions on the diagonal line (inclined) as described above when the insulation distance between the 1 st and 2 nd discharge portions is secured. In this case, the 1 st conductive portion having the same voltage as the 1 st discharge portion surrounding or partially surrounding the 1 st discharge portion where thepositive ions are generated is arranged, and the 2 nd discharge portion where the negative ions are generated also has the same structure. The 1 st conductive portion and the 2 nd conductive portion are arranged facing each other on the same plane and independently separated from each other. The positive ions emitted from the 1 st discharge site are emitted together with the wind by repulsion of the 1 st conductive site of the same voltage surrounding the 1 st discharge site before being neutralized by the reverse potential of the 2 nd discharge site. The same applies to the 2 nd discharge site. In this case, the electrodes may be needle-shaped as described above, but basically, a structure in which a pair of electrodes is constituted by a discharge electrode provided on the surface of a dielectric and an inductive electrode embedded in the dielectric is considered.
The ion generating element of the present invention includes at least 1 of the 1 st discharge portion and the 2 nd discharge portion, each of which is mounted or printed on the 1 st base material and generates positive ions and negative ions, wherein the 1 st and 2 nd discharge portions are formed by a pair of the 1 st and 2 nd discharge electrodes provided on the surface of the dielectric material as the base material and the 1 st and 2 nd induction electrodes embedded in the dielectric material, and are arranged separately and independently from each other on the same plane of the base material. According to this configuration, as compared with a system in which positive ions and negative ions are alternately generated at a predetermined cycle by a single ion generating element, neutralization between generated ions can be suppressed.
In addition, when the 1 st discharge portion and the 2 nd discharge portion are disposed with the 1 st discharge electrode and the 2 nd discharge electrode being spaced apart by a predetermined distance, it is possible to preventa spark (spark discharge) from occurring between the 1 st and 2 nd discharge electrodes, improve reliability, and further suppress neutralization between generated ions.
In the structure in which a pair of electrodes is constituted by a discharge electrode provided on the surface of a dielectric and an induction electrode embedded in the dielectric, in order to reduce the generation of ozone, the voltage waveforms applied to the 1 st discharge part and the 2 nd discharge part are not the common ac sine waves as in patent documents 2 and 3, and in the ion generating element of the present invention, by applying an ac pulse voltage, it is possible to obtain stable ion generation and suppress ozone to a low value. The structure is such that positive ions are generated by applying a voltage waveform for biasing the AC pulse voltage to positive in the 1 st discharge part and negative ions are generated by applying a voltage waveform for biasing the same voltage to negative in the 2 nd discharge part.
Further, the voltage application circuit includes: a 1 st voltage applying unit and a converting unit capable of converting between a case where positive ions are generated by applying a voltage waveform in which an ac pulse voltage is biased to be positive to a 1 st discharging unit of the ion generating element and a case where only negative ions are generated by applying a voltage waveform in which the same voltage is biased to be negative; and a 2 nd voltage applying part for applying a voltage waveform for biasing the same ac pulse voltage to a negative voltage to the 2 nd discharge part of the ion generating element to generate negative ions; therefore, the case of generating both positive and negative ions and the state of releasing only negative ions can be selected and switched. The polarity type of the generated ions can be automatically or manually switched depending on the environment and situation of use of the ion generating apparatus and the purpose of use. When positive ions and negative ions are generated, the purpose is to inactivate fungi and viruses floating in the air, and when only negative ions are generated, it is effective in the case where it is desired to change the state of excess positive ions due to electrical equipment in the home or the like to a state of ion balance or a relaxation effect is required. These switching functions are achieved with one electrode, one ion generating device.
In order to realize the switching function at a lower cost and with a smaller number of components, the voltage application circuit includes: a 3 rd voltage applying unit and a bias switching unit capable of switching between a case where positive ions are generated by applying a voltage waveform in which an ac pulse voltage is biased to a positive voltage to a 1 st discharge portion of the ion generating element and a case where positive ions and negative ions are generated by applying an alternating voltage waveform in which the same voltage is not biased; a 2 nd voltage applying unit for applying a voltage waveform that is negative with respect to the ac pulse voltage to the 2 nd discharge unit of the ion generating element to generate negative ions; thus, it is possible to select and switch between a state in which substantially equal amounts of both positive and negative ions are generated and a state in which a small amount of positive ions and a large amount of negative ions larger than the positive ions are generated. The polarity type of the generated ions can be automatically or manually switched according to the environment and situation of use of the ion generating apparatus and the purpose of use. When positive ions and negative ions are generated in substantially equal amounts, the purpose is to inactivate fungi and viruses floating in the air, and when a large amount of negative ions are generated, it is effective when it is desired to change the state of excess positive ions dueto electrical equipment in a home or the like to a state of ion balance or to relax the state. These switching functions are implemented with 1 ion generating device.
The alternating current pulse voltage applied to the 1 st discharge portion may be an alternating voltage waveform in which the voltage of the 1 st inductive electrode with respect to the 1 st discharge electrode starts from a positive polarity, and the alternating current pulse voltage applied to the 2 nd discharge portion may be an alternating voltage waveform in which the voltage of the 2 nd inductive electrode with respect to the 2 nd discharge electrode starts from a negative polarity. In other words, the 1 st wave of the voltage of the 1 st sensing electrode with respect to the 1 st discharge electrode increases in the positive polarity side, and the 1 st wave of the voltage of the 2 nd sensing electrode with respect to the 2 nd discharge electrode increases in the negative polarity side.
Further, the voltage applying circuit includes: a 1 st diode having a cathode connected to a reference potential (ground potential: described in the embodiment) and an anode connected to a 2 nd discharge electrode; and a 2 nd diode having an anode connected to the reference potential and a cathode connected to the 1 st discharge electrode. If it is possible to switch whether or not the 2 nd diode is connected to the reference potential, it is possible to selectively apply the alternating voltage waveform with the alternating pulse voltage applied to the 2 nd discharge electrode being biased negative, the alternating voltage waveform with the alternating pulse voltage applied to the 1 st discharge electrode being biased positive, or the alternating voltage waveform without being biased.
Further, the voltage application circuit may include: a 1 st diode having a cathode connected to a reference potential and an anode connected to a 2 nd discharge electrode; a2 nd diode having an anode connected to the reference potential and a cathode connected to the 1 st discharge electrode when positive ions are generated from the 1 st discharge portion; and a 3 rd diode, when negative ions are generated from the 1 st discharge part, the cathode is connected with the reference potential, and the anode is connected with the 1 st discharge electrode. Thereby, the ac pulse voltage applied to the 2 nd discharge electrode can be biased negative, and the ac pulse voltage applied to the 1 st discharge electrode can be biased positive or negative.
Further, the voltage applying circuit includes a 1 st transformer including a primary coil on a driving side, a 1 st secondary coil for applying the ac pulse voltage to the 1 st discharge portion, and a 2 nd secondary coil for applying the ac pulse voltage to the 2 nd discharge portion, and when the 1 st and 2 nd secondary coils of the 1 st transformer are respectively disposed on both sides of the primary coil, a distance between the 1 st and 2 nd secondary coils can be secured, and an influence of a magnetic field generated in one secondary coil directly on the other secondary coil can be reduced.
Further, the voltage applying circuit includes: a 2 nd transformer including a primary coil on a driving side and a secondary coil for applying an ac pulse voltage to the 1 st discharge portion; and a 3 rd transformer including a primary coil on a driving side and a secondary coil for applying an alternating-current pulse voltage to the 2 nd discharge portion, wherein when the secondary coil of the 2 nd transformer, the primary coil of the 3 rd transformer, and the secondary coil of the 3 rd transformer are arranged in this order, a distance between the secondary coil of the 2 nd transformer and the secondary coil of the 3 rd transformer can be secured, and an influence of a magnetic field generated in one secondary coil directly on the other secondary coil canbe reduced.
Further, when the primary coil of the 2 nd transformer and the primary coil of the 3 rd transformer are connected in parallel, the voltages applied to the primary coil of the 2 nd transformer and the primary coil of the 3 rd transformer are equal, so that the absolute values of the ac pulse voltages applied to the 1 st discharge portion and the 2 nd discharge portion can be made equal by equalizing the characteristics of the 2 nd transformer and the 3 rd transformer.
Further, when the primary coil of the 2 nd transformer and the primary coil of the 3 rd transformer are connected in series, since currents flowing through the primary coil of the 2 nd transformer and the primary coil of the 3 rd transformer are equal, the absolute values of the ac pulse voltages applied to the 1 st discharge portion and the 2 nd discharge portion can be made equal by equalizing the characteristics of the 2 nd transformer and the 3 rd transformer.
In addition, when a freewheeling diode (freewheeling diode) is connected to each of the primary winding of the 2 nd transformer and the primary winding of the 3 rd transformer, the influence on the 3 rd transformer disappears because a current flowing due to a voltage induced in the primary winding of the 2 nd transformer by a current flowing through the secondary winding of the 2 nd transformer flows back to the primary winding of the 2 nd transformer and the freewheeling diode connected thereto. Similarly, since a current flowing due to a voltage induced in the primary coil of the 3 rd transformer by a current flowing through the secondary coil of the 3 rd transformer flows back to the primary coil of the 3 rd transformer and the flywheel diode connected thereto, the influence on the 2 nd transformer is also eliminated. Therefore, even if a load fluctuation or the like occurs in one discharge portion, the influence of the fluctuation on the voltage applied to the other discharge portion is eliminated, and a fluctuation in the amount of ions generated from the other discharge portion can be prevented.
In the ion generating element having the above-described configuration, the discharge electrode contact and the induction electrode contact for applying a predetermined voltage waveform to the discharge electrode and the induction electrode of the 1 st and 2 nd discharge parts are surfaces of a dielectric material and are disposed on a surface opposite to the discharge electrode so as not to hinder discharge and generated ions. The number of the 1 st and 2 nd contacts is 4 in total, and the 1 st discharge electrode contact and the 2 nd discharge electrode contact having the lowest potential difference are arranged adjacently at a constant distance in the positional relationship, and the reliability can be further improved.
Similarly, the arrangement of the 1 st and 2 nd discharge portions on the substrate is also such that the 1 st and 2 nd discharge electrodes having the smallest potential difference are arranged at a constant distance from each other, and the reliability can be further improved.
Further, the electrical device of the present invention may be configured such that: any one of the ion generating devices having the above-described configuration and a sending unit (such as a fan) for sending out the ions generated by the ion generating device into the air are provided. With this configuration, the amount of ions in the air and the ion balance can be changed in the ion generator mounted with the function inherent in the device, and the indoor environment can be brought into a desired atmospheric state.
Further, the electric device having the above-described structure generates H as positive ions+(H2O) m as negative ion generating O2 -(H2O)n(m, n are naturalnumbers, meaning that there are a plurality of H' s2O molecules). Thus, H is generated in the air substantially equally+(H2O)mAnd O2 -(H2O)nAccordingly, both ions are attached to airborne bacteria and the like, and the activity of the airborne bacteria can be inactivated by the action of hydroxyl groups (. OH) of radicals generated at that time.

Detailed Description
The ion generator according to the present invention is configured not to alternately generate positive ions and negative ions at a predetermined cycle by a single ion generating element but to individually generate positive ions and negative ions by a plurality of ion generating elements and to emit the generated positive ions and negative ions into a room independently (hereinafter, referred to as an ion independent emission system) in order to suppress the generated positive ions and negative ions from being neutralized near an electrode of the ion generating element and to extinguish the ions and to efficiently emit the generated ions of both polarities into the space.
Before the above-described ion independent emission method was adopted, the following basic experiment was performed. In the present experiment, a needle-like electrode was used as an ion generating element, but here, a structure in which a pair of electrodes is constituted by a discharge electrode provided on the surface of a dielectric and an inductive electrode embedded in the dielectric is considered.
Fig. 1A to 1H are schematic diagrams showing basic experimental examples of the ion independent emission system of the present invention. Fig. 1A is an external view of an ion generating element, fig. 1B is a sectional view of the ion generating element, fig. 1C is a voltage application waveform between a discharge electrode and an induction electrode, fig. 1D to 1G are measurement condition diagrams, and fig. 1H is an arrangement example of the ion generating element.
First, in this experiment, the ion generating device 1 shown in fig. 1A and 1B was used to measure the amount of ion emission and verify how there is a difference between positive ions and negative ions in a case where positive ions and negative ions are alternately generated at a predetermined cycle by applying an ac pulse voltage (fig. 1C) between the discharge electrode 0a and the inductive electrode 0B (fig. 1D) and only negative ions are generated by applying a waveform that biases the ac pulse voltage to negative (not shown) using the same ion generating device 1. As a result, the total amount of positive ions and negative ions detected in the former is only about 50 to 60 [%]of the amount of negative ions detected in the latter.
Next, focusing on the above results, 2 ion generating elements 1a and 1b similar to those described above were arranged side by side, and the total ion emission amounts in the case where only positive ions and only negative ions were generated individually were measured (fig. 1E to 1G).
As a result, the total detected amount of positive ions and negative ions obtained under the measurement conditions of fig. 1E is substantially equal to the total detected amount of positive ions and negative ions obtained when the ion emission amount is individually measured using the 2 ion generating elements. As described above, it is effective to use an ion generating element in which positive ions and negative ions are alternately generated at a predetermined cycle by a single ion generating element, and an ion generating element in which ions are independently emitted.
However, in fig. 1E, the 1 st discharge portion (ion generating element 1a) and the 2 nd discharge portion (ion generating element 1b) are arranged side by side in a direction orthogonal to the air flow from the fan 2, and the air flow passing through one ion generating element does not pass through the other ion generating element.
On the other hand, as shown in fig. 1F and 1G, when the placement method is changed by 90 degrees from fig. 1E and the ion generating elements 1a and 1b are arranged side by side in the direction parallel to the air flow from the fan 2, it is confirmed that the amount of ions generated in the discharge portion located upwind is attenuated. When specifically described, in fig. 1F, since the positive ions generated by the ion generating element 1a in the upwind pass through the ion generating element 1b in the downwind, the positive ions are neutralized by the negative potential of the ion generating element 1b, and the amount of the positive ions is attenuated. Similarly, in fig. 1G, the negative ions of the upwind ion generating element 1b are attenuated. It is thus understood that even if the ion independent discharge system is adopted, ions cannot be efficiently discharged due to the arrangement of the discharge portion, and one ion attenuates, resulting in a breakdown in the discharge balance between positive ions and negative ions.
Here, the measurement of the ions is performed by an ion counter 3 having a double cylindrical shape of gedien (gerrien), and the concentration [ pieces/cc]at the measurement point is obtained as the actual measurement value. Since the ion concentration obtained at the same measurement point under the same conditions is measured, the concentration level is expressed in terms of the amount of ions.
In the case where the ion generating device is mounted inside the apparatus, in order to prevent ions generated in the discharge portion in the windward from being neutralized in the discharge portion in the opposite polarity to the downwind even if the air blown from the apparatus causes the discharge electrode surface on the dielectric to be blown in any one direction of the X-axis direction and the Y-axis direction, it is preferable to arrange the ion generating elements 1a and 1b diagonally, i.e., obliquely, with respect to the direction of the X-axis or the Y-axis direction of the air blowing so as to reduce the neutralization (see fig. 1H). However, since the area is disadvantageous, it is desirable that the air flow direction is not diagonally arranged when the air flow direction is determined.
Further, a basic experiment was conducted to examine the relationship between the distance between the discharge electrodes of the discharge electrode generating positive ions and the discharge electrode generating negative ions and the amount of neutralization of both generated ions. Fig. 6A to 6D are schematic diagrams showing other basic experiments of the ion independent emission system of the present invention. Fig. 6A is an electrode layout diagram on the front side of the thin-film electrode, fig. 6B is an electrode layout diagram on the back side of the thin-film electrode, fig. 6C is a voltage application waveform between the discharge electrode and the induction electrode, and fig. 6D is a measurement condition diagram.
In fig. 6A to 6D, reference numeral 60 denotes a thin film electrode in which 2 electrodes are formed on each of the front surface side and the back surface side by printing copper on a polyimide film and etching the copper. As shown in fig. 6A, discharge electrodes 61a and 62a having a substantially rectangular inner part in a grid shape are formed on the front surface at positions spaced apart from each other by a distance d between the discharge electrodes, and as shown in fig. 6B, inductive electrodes 61B and 62B having a substantially rectangular solid shape are formed on the rear surface at positions facing the discharge electrodes 61a and 62 a. In order to prevent abnormal discharge from occurring at the ends of the discharge electrodes 61a and 62a, the inductive electrodes 61b and 62b are formed to be smaller on the inner side than the discharge electrodes 61a and 62 a.
The portions indicated by the black circles provided on the respective electrodes are bonding pads 63, and high voltage is applied to the respective electrodes via a lead wire or the like bonded thereto to cause discharge and generate ions. An alternating pulse voltage having an alternating vibration attenuation waveform as shown in fig. 6C is biased positive and applied between the discharge electrode 61a and the inductive electrode 61b, and the same alternating pulse voltage is biased negative and applied between the discharge electrode 62a and the inductive electrode 62 b. Thereby, positive ions are generated from the discharge electrode 61a, and negative ions are generated from the discharge electrode 62 a. The 1 st wave of the applied ac pulse voltage has a peak value Vop of about 3 kV.
Then, a plurality of thin film electrodes 60 having a varying distance D between discharge electrodes are prepared, and as shown in fig. 6D, the thin film electrodes 60 are placed between the fan 2 and the ion counter 3, and the alternating pulse voltage is biased to positive and negative waveforms to measure the ion concentrations of both the generated positive and negative ions, respectively, for each thin film electrode 60. The measurement was performed for the case of generating only positive ions, the case of generating only negative ions, and the case of generating both positive and negative ions at the same time, type 3. In this case, the distance between the ion generating element 60 and the ion counter 3 was 25cm, and both were disposed at positions 4.5cm above the measurement stage.
Fig. 7 is a graph showing the measurement results. The temperature and humidity during the measurement were 27 ℃ and 27%. From the measurement results, it is understood that if the distance d between the discharge electrodes is 5mm or more, no spark (spark discharge) occurs between the discharge electrodes 61a, 62 a. When the distance d between the discharge electrodes was set to 8mm, the number of ions generated in both positive and negative ions was equal to the number of ions generated in both cases. It is understood from this that, under the conditions of the thin film electrode used in the measurement, if the distance d between the discharge electrodes is set to 8mm or more, the neutralization of both positive and negative ions can be prevented. Although the larger the distance d between the discharge electrodes is,the more advantageous the prevention of sparking and the prevention of neutralization of both ions are, the larger the distance is, the larger the size of the ion generating element is, so that it is considered that the distance d between the discharge electrodes may be set to about 8mm under the above-mentioned conditions. Further, when a sample in which the distance d between the discharge electrodes was varied was prepared, the thin-film electrode used for the measurement was etched to secure the distance d between the discharge electrodes, and only the coating layer covering the electrode surface was removed at that portion, so that copper was exposed to a portion of the end surfaces of the discharge electrodes facing each other. Therefore, in the actual electrodes described below, it is estimated that the value of the inter-discharge-electrode distance d can be made smaller by the presence of the coating layer.
As shown in fig. 1H, the ion generating elements 1a and 1B are arranged diagonally, that is, in an inclined arrangement, and the embodiment 1 in which the ion generating elements are embodied (arranged diagonally) is shown in fig. 2A and 2B, depending on the results of the above-described basic experiment in which it is desired to reduce the neutralization. Fig. 2A and 2B are schematic configuration diagrams showing embodiment 1 of the ion generating device of the present invention, and fig. 2A and 2B schematically show a plan view and a side view of the ion generating device, respectively.
As shown in fig. 2A and 2B, the ion generating device of the present invention includes: an ion generating element 10 provided with a plurality of (2 in the present embodiment) discharge portions that generate ions; and a voltage applying circuit 20 for applying a predetermined voltage to the ion generating element 10.
The ion generating element 10 includes: a dielectric 11 (an upper dielectric 11a and a lower dielectric 11b), a 1 st discharge portion 12 (a discharge electrode 12a, an inductive electrode 12b, a discharge electrode contact 12c, an inductive electrode contact 12d, connection terminals 12e and 12f, and connection paths 12g and 12h), a 2 nd discharge portion 13 (a discharge electrode 13a, an inductive electrode 13b, a discharge electrode contact 13c, an inductive electrode contact 13d, connection terminals 13e and 13f, and connection paths 13g and 13h), and a coating layer 14, wherein voltage application described later is performed between the 1 st discharge electrode 12a and the inductive electrode 12b and between the 2 nd discharge electrode 13a and the inductive electrode 13b, and discharge is performed in the vicinity of the discharge electrodes 12a and 13a, thereby generating positive ions and negative ions, respectively.
The dielectric 11 is formed by bonding an upper dielectric 11a and a lower dielectric 11b (for example, 15[ mm]in length, 37[ mm]in width, and 0.45[ mm]in thickness) in a substantially rectangular parallelepiped shape. If an inorganic substance is selected as the material of the dielectric 11, ceramics such as high-purity alumina, crystal glass, forsterite, and steatite can be used. Further, if an organic substance is selected as the material of the dielectric 11, resins such as polyimide and glass epoxy resin excellent in oxidation resistance are suitable. However, in view of corrosion resistance, it is preferable to select an inorganic material as the material of the dielectric 11, and further, in view of formability and easiness of electrode formation described later, it is preferable to use ceramic forming.
Further, since it is desirable that the insulation resistance between the discharge electrodes 12a and 13a and the inductive electrodes 12b and 13b is uniform, the material having a uniform insulation ratio is more suitable as the material of the dielectric 11 as the density variationis smaller.
The shape of the dielectric 11 may be other than a substantially rectangular parallelepiped shape (circular plate shape, elliptical plate shape, polygonal plate shape, etc.) and may be a cylindrical shape, but in consideration of productivity, it is preferable to form the dielectric in a flat plate shape (including circular plate shape and rectangular parallelepiped shape) as in the present embodiment.
The 1 st and 2 nd discharge portions 12 and 13 are arranged on diagonal lines (inclined) with respect to the shape of the dielectric 11 of the base material so as not to be aligned with each other. When further expressed functionally, the 1 st and 2 nd discharge portions 12, 13 are arranged: even if an air flow is sent to the ion generating element 10 of the present embodiment from any one direction, the arrangement direction thereof is made orthogonal to the air flow, in other words, the air flow passing over one discharge portion does not pass over the other discharge portion. With this configuration, the effect of the independent ion emission system can be utilized flexibly, and ion attenuation occurring in the two discharge portions 12 and 13 can be suppressed, thereby effectively performing ion emission with good balance.
The discharge electrodes 12a and 13a are formed integrally with the upper dielectric 11a on the surface of the upper dielectric 11 a. The material of the discharge electrodes 12a and 13a is not particularly limited as long as it is a material having conductivity, such as tungsten, for example, but it is a material that does not cause deformation such as melting due to discharge.
The inductive electrodes 12b and 13b are disposed in parallel with the discharge electrodes 12a and 13a with the upper dielectric 11a interposed therebetween. With such an arrangement, the distance between the discharge electrodes 12a, 13a and the inductive electrodes 12b, 13b (hereinafter referred to as an inter-electrode distance) can be made constant, so that the insulation resistance between both electrodes can be made uniform to stabilize the discharge state, and positive ions and/or negative ions can be generated appropriately. When the dielectric 11 is formed in a cylindrical shape, the discharge electrodes 12a and 13a are provided on the outer peripheral surface of the cylindrical shape, and the distance between the electrodes can be made constant by providing the inductive electrodes 12b and 13b in a shaft shape.
As the material of the inductive electrodes 12b and 13b, similarly to the discharge electrodes 12a and 13a, for example, a material having conductivity such as tungsten may be used without any particular limitation, provided that it does not cause deformation such as melting due to discharge.
The discharge electrode contacts 12c and 13c are electrically connected to the discharge electrodes 12a and 13a via connection terminals 12e and 13e and connection paths 12g and 13g provided on the same formation surface (i.e., the surface of the upper dielectric 11 a) as the discharge electrodes 12a and 13 a. Therefore, one end of a lead wire (copper wire, aluminum wire, or the like) is connected to the discharge electrode contacts 12c and 13c, and the other end of the lead wire is connected to the voltage application circuit 20, whereby the discharge electrodes 12a and 13a can be electrically connected to the voltage application circuit 20.
The inductive electrode contacts 12d, 13d are electrically connected to the inductive electrodes 12b, 13b via connection terminals 12f, 13f and connection paths 12h, 13h provided on the same formation surface (i.e., the surface of the lower dielectric 11b) as the inductive electrodes 12b, 13 b. Therefore, one end of a lead (copper wire, aluminum wire, or the like) is connected to the inductive electrode contacts12d and 13d, and the other end of the lead is connected to the voltage application circuit 20, whereby the inductive electrodes 12b and 13b can be electrically conducted to the voltage application circuit 20.
Further, it is preferable that all of the discharge electrode contacts 12c and 13c and the inductive electrode contacts 12d and 13d are provided on the surface of the dielectric 11, that is, on the surface other than the surface on which the discharge electrodes 12a and 13a are provided (hereinafter, referred to as the upper surface of the dielectric 11). With such a configuration, since unnecessary leads or the like are not provided on the upper surface of the dielectric member 11, the air flow from the fan (not shown) is less likely to be disturbed, and the effect of the independent ion emission system of the present invention can be exhibited to the maximum extent.
In view of the above, in the ion generating device 10 of the present embodiment, all of the discharge electrode contacts 12c and 13c and the inductive electrode contacts 12d and 13d are provided on a surface facing the upper surface of the dielectric 11 (hereinafter, referred to as a lower surface of the dielectric 11).
In the ion generating element 10 of the present embodiment, the 1 st discharge electrode 12a and the 2 nd discharge electrode 13a have acute-angled portions, and the electric field is concentrated in the acute-angled portions, thereby causing partial discharge. Of course, patterns other than the electrodes described in this figure may be used as long as the electric field can be concentrated. The same processing is performed in fig. 3, 4A, and 4B below.
Fig. 3 is a schematic plan view showing embodiment 2 of the ion generating device of the present invention. The structure of the cross-sectional view can be considered to be the same as that of fig. 2B. Fig. 3 shows an embodiment in which the 1 st and 2 nd discharge sites are not arranged on diagonal lines with respect to the shape of the base material 11 due to the limitation in area.
The 1 st discharge electrode 12a is classified into a 1 st discharge site 12j where electric discharge is caused by concentration of an electric field, a 1 st conductive site 12k surrounding or partially surrounding the 1 st discharge site, and the above-mentioned connection terminal portion 12 e. These are all located on the same pattern and the applied voltages are equal. Similarly, the 2 nd discharge electrode 13a includes a 2 nd discharge site 13j, a 2 nd conductive site 13k, and a connection terminal portion 13 e.
The 1 st discharge site 12j generates positive ions at a positive potential, and a 2 nd discharge site 13j of a negative potential exists in its immediate vicinity.
Here, it is characterized in that: the 1 st and 2 nd conductive sites 12k and 13k surrounding or partially surrounding the 1 st and 2 nd discharge sites 12j and 13j causing discharge are arranged. In this way, since the 1 st electrically conductive site 12k having the same voltage as the 1 st discharge site 12j surrounds or partially surrounds the 1 st discharge site 12j, the positive ions generated from the 1 st discharge site 12j can be prevented from reaching the 2 nd discharge site 13j by repulsion of the 1 st electrically conductive site 12k having a positive potential before reaching the 2 nd discharge site 13j having a negative potential of the opposite polarity. The same applies to the 2 nd discharge site 13 k. In the case of the blowing direction in which the generated ions are hardly neutralized and the distance between the 1 st discharge electrode 12a and the 2 nd discharge electrode 13a, the 1 st conductive site 12k and the 2 nd conductive site 13k, which are the above-described characteristic portions, may not be provided.
Fig.4A and 4B are schematic plan views showing embodiment 3 of the ion generating device of the present invention. The structure of the cross-sectional view can be considered to be the same as that of fig. 2B. The ion generating device shown in fig. 4A and 4B has the features of embodiment 2 described above, and the dielectric 11 of the base material is arranged diagonally as described above. As described above, the electrode may be a needle-like electrode, but basically, a pair of electrodes is formed by a discharge electrode provided on the surface of a dielectric and an induction electrode embedded in the dielectric.
The invention according to embodiment 4 is characterized in that: in the ion generating device shown in fig. 2A, 2B, 3, 4A, and 4B, when the arrangement of the 1 st discharge electrode 12A, the 1 st inductive electrode 12B, the 2 nd discharge electrode 13a, and the 2 nd inductive electrode 13B with respect to the dielectric 11 is considered, although the electrodes are adjacent to each other with a distance that can ensure insulation between the 1 st and 2 nd electrodes, it is characterized in that, in view of the applied voltage: the 1 st discharge electrode 12a and the 2 nd discharge electrode 13a which are the smallest in potential difference among the 2 electrodes are adjacent to each other with a distance therebetween which can ensure insulation. In other words, the electrodes are configured to be adjacent to each other at a distance that ensures the combined electrode insulation with the minimum potential difference. The potential difference and the waveform will be described below.
The electrode shapes shown in fig. 2A, 3, 4A, and 4B are examples, and may be those shown in fig. 8 to 11. Fig. 8 to 11 are schematic plan views showing 5 th to 8 th embodiments of the ion generating device of the present invention. In fig. 8 to 11, the same portions as those in fig. 3 are denoted by the same reference numerals, and the description thereof will be omitted. The structure of the cross-sectional view may be considered to be the same as that of fig. 2B.
The ion generating device 10 shown in fig. 8 is a device in which the size of each electrode is made small so that the end faces of the 1 st discharge electrode 12a and the 2 nd discharge electrode 13a do not come too close to each other, and the ion generating device 10 shown in fig. 9 is a device in which the number of the 1 st discharge electrode 12a and the 2 nd discharge electrode 13a of the ion generating device 10 shown in fig. 8 is reduced in order to adjust the discharge position. The ion generating device 10 shown in fig. 10 and 11 is a device in which the shape of the 1 st discharge electrode 12a and the 2 nd discharge electrode 13a of the ion generating device 10 shown in fig. 9 is made close to the image of the 1 st discharge electrode 12a and the 2 nd discharge electrode 13a of the ion generating device 10 shown in fig. 2 in order to adjust the discharge position.
Next, the structure and operation of the voltage application circuit 20 will be described.
Fig. 5A and 5B are circuit diagrams showing an embodiment of the voltage application circuit 20. First, the voltage application circuit 20 shown in fig. 5A is explained. The voltage application circuit 20 shown in fig. 5A includes, as a primary side drive circuit: an input power supply 201, an input resistor 204, a rectifier diode 206, a transformer driving switching element 212, a capacitor 211, and a diode 207. When the input power supply 201 is an ac commercial power supply, the capacitor 211 is charged with the voltage of the input power supply 201 via the input resistor 204 and the rectifier diode 206, and when the voltage is equal to or higher than a predetermined voltage, the transformer driving switching element 212 is turned on, and a voltage is applied to the primarywinding 202a of the transformer 202. Then, the energy charged in the capacitor 211 is discharged through the primary winding 202a of the transformer 202 and the transformer driving switching element 212, the voltage of the capacitor 211 returns to zero, and the capacitor is charged again, and the charging and discharging are repeated at a predetermined cycle. The transformer driving switching element 212 has been described in the above description as a non-gate 2-terminal thyristor ("Sidac" [ product of the new electrical industry]), but a thyristor (SCR) may be used as well as several different circuits. Note that, even when the input power supply 201 is a dc power supply, any circuit may be used as long as it can obtain the same operation as described above. That is, the primary side driver circuit of this circuit is not particularly limited as long as it can obtain the same operation.
As the secondary side circuit of the transformer 202, 2 secondary coils 202B and 202c of the transformer 202 are provided, and these coils are connected to the 1 st discharge electrode 12A, the 1 st inductive electrode 12B, the 2 nd discharge electrode 13a, and the 2 nd inductive electrode 13B of any one of fig. 2A, fig. 2B, fig. 3, fig. 4A, fig. 4B, and fig. 8 to fig. 11, respectively. When the transformer driving switching element 212 of the primary side circuit is turned on, the primary side energy is transmitted to the secondary coils 202b and 202c of the transformer, and a pulse-like voltage is generated. The 1 st discharge electrode 12a is connected not only to the secondary winding 202b of the transformer 202 but also to the cathode of a diode 209, and the anode of the diode 209 is connected to the ground via a resistor 205 or to one side (reference potential) of the input power supply 201. When the input power supply 201 is an ac commercial power supply, since one side of the ac commercial power supply is grounded in japan, the same function can be obtained if an electric device or thelike having no ground terminal is connected to one side of the input power supply 201. Even if the socket is inserted in reverse, it overlaps only 100V, as is the ground. The resistor 205 is for protection, and does not affect the operation even without the resistor (short circuit). Further, not only the secondary winding 202c of the transformer but also the anode of the diode 208 are connected to the 2 nd discharge electrode 13a, and the cathode of the diode 208 is grounded via the resistor 205 or connected to one side of the input power supply 201.
Next, a voltage application circuit 20 having another configuration shown in fig. 5B will be described. The description of the primary side circuit of the transformer 202 is the same as described above. As a secondary side circuit of the transformer 202, the secondary coil of the transformer 202 includes 2 coils 202B and 202c, and these coils are connected to the 1 st discharge electrode 12A, the 1 st inductive electrode 12B, the 2 nd discharge electrode 13a, and the 2 nd inductive electrode 13B of any one of fig. 2A, fig. 2B, fig. 3, fig. 4A, fig. 4B, and fig. 8 to fig. 11, respectively. The 1 st discharge electrode 12a is connected not only to the secondary winding 202b of the transformer 202 but also to the cathode of the diode 209 and the anode of the diode 210, the anode of the diode 209 is connected to the 1 selection terminal 203a of the switching relay 203, and the cathode of the diode 210 is connected to the other selection terminal 203b of the switching relay 203. The common terminal 203c of the switching relay 203 is grounded via a resistor 205 or connected to one side of the input power supply 201.
Next, the operating voltage waveform is explained. A pulse waveform of an alternating voltage as shown in fig. 5C is applied to both ends of the secondary coils 202b and 202C of the transformer 202. The direction of the diode 209 and the diode 208 connected to the secondary coils 202b and 202C is reversed as described above, and the waveform when the voltages of the 1 st discharge electrode 12a, the 1 st inductive electrode 12b, the 2 nd discharge electrode 13a, and the 2 nd inductive electrode 13b are observed with the ground terminal and, as the case may be, with one side (reference potential: the side to which the diodes 208 and 209 are connected) of the input power supply 201 as a reference, as shown in fig. 5D, 5E, 5F, and 5G, the waveform in fig. 5C is a waveform biased to positive and negative, respectively.
In the embodiment shown in fig. 5A, the potentials of the 1 st discharge electrode 12a and the 1 st inductive electrode 12b, which are observed with respect to the ground terminal and, as the case may be, the one side of the input power supply 201 (the side to which the diodes 208 and 209 are connected) as a reference, are both positive, and the generated negative ions are neutralized by the discharge electrode 12a, and the positive ions are repelled and released. The 2 nd discharge electrode 13a and the 2 nd inductive electrode 13b are both negative in potential observed with reference to the ground terminal and, in some cases, one side (reference potential: the side to which the diodes 208 and 209 are connected) of the input power supply 201, and emit negative ions.
In the embodiment shown in fig. 5B, when the switching relay 203 is positioned on the selection terminal 203a side, the 1 st discharge electrode 12a and the 1 st inductive electrode 12B are both positive in potential as viewed from the ground terminal and, as the case may be, from one side of the input power supply 201 (the reference potential: the side to which the diodes 208 and 209 are connected), and positive ions are generated. When the switching relay 203 is located on the selection terminal 203b side, the potential observed with reference to the ground terminal and, in some cases, the one side of the input power supply 201 (the reference potential: the side to which the diodes 208 and 209 are connected) is negative, and negative ions are generated. The 2 nd discharge electrode 13a and the 2 nd inductive electrode 13b are both negative in potential as viewed from the ground terminal and, in some cases, from one side (reference potential: the side to which the diodes 208 and 209 are connected) of the input power supply 201, and generate negative ions.
As positive ion is H+(H2O)mAs negative ion, O2 -(H2O)n(m, n are natural numbers, meaning that there are a plurality of H' s2An O molecule).
Thus, when the selection terminal of the relay 203 is switchedWhen the ions are located on the 203a side, the ions generated from the 1 st discharge portion 12 become positive ions, and the number of ions is substantially equal to the number of positive and negative ions generated from the 2 nd discharge portion 13. By discharging H in substantially the same amount in the air+(H2O)mAnd O2 -(H2O)nThese ions surround the airborne fungi or viruses, and are deactivated by the action of hydroxyl groups (. OH) of the radicals generated at this time.
The above description is described in detail. By applying an alternating voltage between the electrodes constituting the 1 st and 2 nd discharge parts 12 and 13, oxygen and moisture in the air receive energy by ionization, and are ionized to generate H+(H2O)m(m is an arbitrary natural number) and O2 -(H2O)n(n is arbitrary fromBut) mainly, and these ions are discharged into the space by a fan or the like. These H+(H2O)mAnd O2 -(H2O)nAttached to the surface of planktonic bacteria,and chemically reacted to generate H as a radical2O2Or (. OH). Due to H2O2Or (&OH) exhibits extremely strong activity, and thus, can surround airborne bacteria and inactivate them. Here, (. OH) is 1 type of radical and represents a radical OH.
The positive and negative ions chemically react on the cell surface of the floating bacteria as shown in the formulae (1) to (3) to generate hydrogen peroxide H as a radical2O2Or a hydroxyl group (. OH). In the formulae (1) to (3), m ', n, and n' are arbitrary natural numbers. This destroys the floating bacteria by the decomposition action of the radicals. Therefore, airborne bacteria in the air can be effectively inactivated and removed.
By releasing the positive and negative ions through the above mechanism, a deactivating effect of floating bacteria and the like can be obtained.
Further, since the above-mentioned formulas (1) to (3) can generate the same action even on the surface of a harmful substance in the air, hydrogen peroxide H as a radical2O2Or hydroxide radical (. OH) oxidizes or decomposes a harmful substance, and converts a chemical substance such as formaldehyde or ammonia into a harmless substance such as carbon dioxide, water, or nitrogen, thereby making it substantially harmless.
Therefore, by driving the blower fan, the positive ions and the negative ions generated by the ion generating element 1 can be sent out of the main body. Further, the action of these positive ions and negative ions inactivates mold and bacteria in the air, thereby inhibiting their proliferation.
In addition, positive ions and negative ions also have an effect of inactivating viruses such as coxsackie virus and poliovirus, and contamination due to contamination of these viruses can be prevented.
Further, it was confirmed that the positive ions and the negative ions have an action of decomposing molecules causing odor, and spatial deodorization can be utilized.
When the selection terminal of the switching relay 203 is located on the 203b side, the ions generated from the 1 st discharge part 12 become negative ions, and the negative ions generated from both electrodes become negative ions together with the negative ions generated from the 2 nd discharge part 13. It is effective when negative ions are supplied in a large amount in a space where there are too many positive ions due to electric equipment in a home or the like, and it is desired to obtain a balanced state between positive ions and negative ions as in a forest in nature or to obtain a relaxation effect.
In addition, the voltage applying circuit 20 may apply an alternating voltage waveform starting from a positive polarity between the 1 st discharge electrode 12A and the 1 st inductive electrode 12B shown in any one of fig. 2A, 2B, 3, 4A, 4B, and 8 to 11, and may apply an alternating voltage waveform starting from a negative polarity between the 2 nd discharge electrode 13a and the 2 nd inductive electrode 13B, and thus, for example, the configuration shown in fig. 12 and 13 may be adopted in addition to the configuration shown in fig. 5A and 5B.
Fig. 12 is a less expensive and reduced component count configuration than the circuit of fig. 5B. For convenience of explanation, the same reference numerals are given to the same parts as those of the embodiment shown in fig. 5B,and the voltage application circuit 20 shown in fig. 12 includes, as a primary side drive circuit: an input power supply 201, an input impedance 204, a rectifier diode 206, a transformer driving switching element 212, a capacitor 211, and a flywheel diode 213. When the input power supply 201 is an ac commercial power supply, the capacitor 211 is charged with the voltage of the input power supply 201 via the input resistor 204 and the rectifier diode 206, and if the voltage becomes equal to or higher than a predetermined voltage, the transformer driving switching element 212 is turned on, and a voltage is applied to the primary winding 202a of the transformer 202. Then, the energy charged in the capacitor 211 is discharged to the primary winding 202a of the transformer 202 through the transformer driving switching element 212, the voltage of the capacitor 211 returns to zero, and the capacitor is charged again, and the charging and discharging are repeated at a predetermined cycle.
As the secondary side circuit of the transformer 202, 2 secondary coils 202B and 202c of the transformer 202 are provided, and these coils are connected to the 1 st discharge electrode 12A, the 1 st inductive electrode 12B, the 2 nd discharge electrode 13a, and the 2 nd inductive electrode 13B of any one of fig. 2A, fig. 2B, fig. 3, fig. 4A, fig. 4B, and fig. 8 to fig. 11, respectively. When the transformer driving switching element 212 of the primary side circuit is turned on, the primary side energy is transmitted to the secondary coils 202b and 202c of the transformer, and a pulse-like voltage is generated. Further, the secondary coils and the electrodes are connected so that the polarity of the voltage applied between the 1 st discharge electrode 12a and the 1 st inductive electrode 12b is opposite to the polarity of the voltage applied between the 2 nd discharge electrode 13a and the 2 nd inductive electrode 13 b.
Further, not only the secondary winding 202b of the transformer 202 but also the cathode of the diode 209 are connected to the 1 st discharge electrode 12a, and the anode of the diode 209 is connected to the ground via the relay 214 or to one side of the input power supply 201 (line AC 2: reference potential). When the input power supply 201 is an ac commercial power supply, since one side of the ac commercial power supply is grounded in japan, the same function can be obtained by connecting an electric device or the like having no ground terminal to one side of the input power supply 201. Further, not only the secondary winding 202c of the transformer 202 but also the anode of the diode 208 are connected to the 2 nd discharge electrode 13a, and the cathode of the diode 208 is grounded or connected to one side (line AC2) of the input power supply 201.
Next, the operating voltage waveform is explained. A pulse waveform of an alternating voltage is applied to both ends of the secondary coils 202b and 202c of the transformer 202. At this time, as shown in fig. 14A, the voltage waveform of the 1 st inductive electrode 12B observed with reference to the 1 st discharge electrode 12a becomes an alternating voltage waveform starting from the positive polarity, and as shown in fig. 14B, the voltage waveform of the 2 nd inductive electrode 13B observed with reference to the 2 nd discharge electrode 13a becomes an alternating voltage waveform starting from the negative polarity.
Further, since the secondary coil 202c is connected to the line AC2 (ground terminal in some cases) via the diode 208 in the forward direction, the voltage waveform of the 2 nd discharge electrode 13a as viewed with reference to the line AC2 is as shown in fig. 15A, and the voltage waveform of the 2 nd inductive electrode 13B is as shown in fig. 15B, and the waveform of fig. 14B is biased to the negative. Therefore, negative ions are generated from the 2 nd discharge portion 13. As negative ion is O2 -(H2O)n(n is a natural number, meaning that there are multiple H' s2An O molecule).
On the other hand, when the relay 214 is turned on, the secondary coil 202B is connected to the line AC2 through the diode 209 in the reverse direction, and therefore, the voltage waveform of the 1 st discharge electrode 12a as viewed with reference to the line AC2 is as shown in fig. 16A, and the voltage waveform of the 1 st induction electrode 12B is as shown in fig. 16B, and the waveform of fig. 14A is biased to be positive. Therefore, positive ions having substantially the same number as that of negative ions generated in the 2 nd discharge portion 13 are generated from the 1 st discharge portion 12. As positive ion is H+(H2O)m(m is a natural number, meaning with multiple H' s2An O molecule).
Fig. 17A is a diagram showing the waveform shown in fig. 14A or 14B with the time axis changed, and fig. 17B is a diagram showing the waveform shown in fig. 16A or 16B with the time axis changed. The voltage waveform applied to each electrode becomes a pulse waveform that decays in such a short time due to the effects of the flywheel diode 213 and the attenuation of the electrical vibration caused by the inductance and resistance of the transformer, the electrostatic capacitance of the electrode. That is, the current flowing through the voltage induced in the primary coil 202a by the current flowing through the secondary coils 202b and 202c flows back through the primary coil 202a, the flywheel diode 213, and the transformer driving switching element 212, and the voltage vibration generated in the secondary coils 202b and 202c is rapidly attenuated.
Fig. 18A is a waveform diagram showing voltage waveforms of the 1 st and 2 nd discharge electrodes 12a and 13a as viewed with reference to the line AC2 when the relay 214 is turned on, and is similar to fig. 15A and 16A. Fig. 18B is a waveform diagram showing voltage waveforms of the 1 st and 2 nd discharge electrodes 12a and 13a as viewed with reference to the line AC2 when the relay 214 is off. When the relay 214 is turned on, as shown in fig. 18A, the voltage waveform of the 1 st discharge electrode 12a indicated by a line L1 is biased to the positive side, and the voltage waveform of the 2 nd discharge electrode 13a indicated by a line L2 is biased to the negative side. When the relay 214 is turned off, as shown in fig. 18B, the voltage waveform of the 2 nd discharge electrode 13a indicated by the line L2 is biased to the negative side and does not change, and the voltage waveform of the 1 st discharge electrode 12a indicated by the line L1 is biased and changes to the alternating waveform. This is because when the relay 214 is turned off, the secondary coil 202b is in a floating state, and the 1 st wave is negative, and the 2 nd and subsequent waves are alternating waveforms, and both positive ions and negative ions are emitted in small amounts.
Therefore, when relay 214 is turned off, a small amount of positive ions and negative ions generated from discharge part 1 and a large amount of negative ions generated from discharge part 213 are in a state of ion abundance as a whole with a small amount of positive ions and a large amount of negative ions. On the other hand, when relay 214 is turned on, positive ions generated from discharge part 1 and negative ions generated from discharge part 213 are used to generate substantially equal amounts of positive and negative ions.
Therefore, by turning on/off the relay 214, the following two cases can be switched: by discharging H in substantially equal amounts in the air+(H2O)mAnd O2 -(H2O)nIn the case where these ions surround the airborne fungi and viruses and are deactivated by the action ofhydroxyl groups (. OH) of radicals generated at this time; and a case where negative ions are supplied in a large amount in a space where the amount of positive ions is too large due to electrical equipment in a home or the like, and it is desired to obtain a state of ion balance between positive ions and negative ions as in a natural forest or to achieve a relaxation effect.
The transformer 202 shown in fig. 12 is configured with a coil arrangement as shown in fig. 19. Fig. 19 is a layout diagram showing the arrangement of components of the ion generator equipped with the transformer 202 shown in fig. 12. In fig. 19, 220 denotes an electrode panel portion for forming each electrode (not shown) for discharge, 221 denotes an electrode frame for fixing the electrode panel portion 220, 222 denotes a molding material, 223 denotes a substrate for mounting a circuit component while fixing the transformer 202, and 224 denotes a connector for input and output and a circuit component mounting portion for mounting another circuit component.
The transformer 202 has a structure in which secondary coils 202b and 202c are disposed on both sides of a primary coil 202 a. When the coil arrangement of the transformer 202 is made in this way, the distance between the secondary coils 202b and 202c can be secured, and the influence of the magnetic field generated in one secondary coil directly on the other secondary coil can be reduced. Therefore, the variation in voltage generated in each secondary coil due to the influence of the mutual magnetic field is reduced, and the variation in the amount of ions generated from the ion generating element to which the voltage generated from the secondary coil is applied can be prevented.
Fig. 13 is a circuit diagram showing another embodiment of the voltage application circuit 20. For convenience of explanation, the same reference numerals are given to thesame portions as those of the embodiment shown in fig. 12, and the explanation thereof is omitted. The voltage application circuit 20 shown in fig. 13 is different from the voltage application circuit 20 shown in fig. 12 in that: instead of 1 transformer 202 and freewheeling diode 213, 2 transformers 215, 216 and 2 freewheeling diodes 217, 218 connected to the respective primary windings are used. The positions of the transformer driving switching element 212, which is a primary side driving circuit, and the capacitor 211 are switched.
When the input power supply 201 is an ac commercial power supply, the capacitor 211 is charged with the voltage of the input power supply 201 via the input resistor 204, the rectifier diode 206, and the flywheel diodes 217 and 218, and when the voltage becomes equal to or higher than a predetermined voltage, the transformer driving switching element 212 is turned on, and a voltage is applied to a series circuit of the primary winding 215a of the transformer 215 and the primary winding 216a of the transformer 216. Then, the energy charged in the capacitor 211 is discharged through a series circuit of the transformer driving switching element 212, the primary winding 215a of the transformer 215, and the primary winding 216a of the transformer 216, and the voltage of the capacitor 211 returns to zero and is charged again, and the charging and discharging are repeated at a predetermined cycle.
Secondary coils 215B and 216B, which are secondary circuits of the transformers 215 and 216, are connected to the 1 st discharge electrode 12A, the 1 st inductive electrode 12B, the 2 nd discharge electrode 13a, and the 2 nd inductive electrode 13B of any one of fig. 2A, 2B, 3, 4A, 4B, and 8 to 11, respectively. The transformer driving switching element 212 of the primary side circuit is turned on, and energy on the primary side is transmitted to the secondary coil 215b and the secondary coil 216b, thereby generating a pulse-like voltage. Further, each secondary coil is connected to each electrode: the polarity of the voltage applied between the 1 st discharge electrode 12a and the 1 st sensing electrode 12b is opposite to the polarity of the voltage applied between the 2 nd discharge electrode 13a and the 2 nd sensing electrode 13 b.
Further, not only the secondary coil 215b of the transformer 215 but also the cathode of the diode 209 are connected to the 1 st discharge electrode 12a, and the anode of the diode 209 is connected to the ground via the relay 214 or to one side (line AC2) of the input power supply 201. Further, not only the secondary winding 216b of the transformer 216 but also the anode of the diode 208 are connected to the 2 nd discharge electrode 13a, and the cathode of the diode 208 is grounded or connected to one side (line AC2) of the input power supply 201.
The operating voltage waveform of the voltage application circuit 20 shown in fig. 13 having such a configuration is the same as the operating voltage waveform of the voltage application circuit 20 shown in fig. 12 (fig. 14A to 17A, and fig. 14B to 17B), and therefore, the description thereof is omitted. The voltage application circuit 20 shown in fig. 13 is characterized in that: the transformer 215 for applying a voltage between the 1 st discharge electrode 12a and the 1 st induction electrode 12b and the transformer 216 for applying a voltage between the 2 nd discharge electrode 13a and the 2 nd induction electrode 13b are independent, and flywheel diodes 217 and 218 are provided on the primary coils of the respective transformers, respectively.
In this way, since the current flowing through the voltage induced in the primary coil 215a by the current flowing through the secondary coil 215b flows back only to the primary coil 215a and the freewheeling diode 217, there is no influence on the transformer 216. Similarly, since the current flowing through the voltage induced in the primary coil 216a by the current flowing through the secondary coil 216b flows back only to the primary coil 216a and the freewheeling diode 218, the current does not affect the transformer 215. Therefore, even if a load fluctuation or the like occurs in one discharge portion, the influence of the fluctuation on the voltage applied to the other discharge portion is eliminated, and the fluctuation in the amount of ions generated from the other discharge portion can be prevented.
The voltage application circuit 20 shown in fig. 13 may be a circuit in which the primary coil 215a of the transformer 215 and the primary coil 216a of the transformer 216 are connected in series, or a parallel connection of these components.
The transformers 215 and 216 shown in fig. 13 are configured with a coil arrangement as shown in fig. 20. Fig. 20 is a layout diagram showing the arrangement of components of the ion generator mounted with the transformers 215 and 216 shown in fig. 13. For the sake of convenience of explanation, the same reference numerals are given to the same parts as those in fig. 19. In fig. 20, 220 denotes an electrode panel portion for forming each electrode (not shown) for discharge, 221 denotes an electrode frame for fixing the electrode panel portion 220, 222 denotes a molding material, 223 denotes a substrate for fixing the transformers 215 and 216 and mounting circuit components, and 224 denotes a circuit component mounting portion for mounting connectors for input and output and other circuit components.
The transformers 215, 216 are configured to be arranged in the order of the secondary winding 216b, the primary winding 216a, the primary winding 215a, and the secondary winding 215 b. When the transformers 215, 216 are configured in this way, the distance between the secondary coils 216b, 215b can be ensured, and the influence of the magnetic field generatedin one secondary coil directly on the other secondary coil can be reduced. Therefore, the voltage fluctuation generated in each secondary coil due to the influence of the magnetic fields can be reduced, and the variation in the amount of ions generated from the ion generating element to which the voltage generated from each secondary coil is applied can be prevented.
Although the switching element 212 for driving the transformer shown in fig. 12 and 13 has been described as using a non-gate 2-terminal thyristor ("Sidac" [ product of new electric power generation industry]), a thyristor (SCR) may be used instead using several different circuits. Note that the input power supply 201 may be any circuit as long as it is a circuit capable of obtaining the same operation as described above, even when it is a dc power supply. That is, the primary side driver circuit of this circuit is not particularly limited as long as it can obtain the same operation.
The ion generating element or the ion generating device of the present invention may be mounted in an electric apparatus such as an air conditioner, a dehumidifier, a humidifier, an air cleaner, a refrigerator, a fan heater, a microwave oven, a washing and drying machine, a vacuum cleaner, and a sterilizer. In such an electric apparatus, the amount of ions in the air and the ion balance are changed by an ion generator mounted thereon in addition to the functions inherent in the apparatus, whereby the indoor environment can be brought into a desired atmospheric state.
In the above-described embodiment, the configuration in which positive ions and negative ions are individually generated by a single ion generating element having a plurality of discharge portions for generating ions and are independently emitted into a room has been described as an example, but the configuration of the present invention is not limited to this configuration, and may be a configuration in which positive ions and negative ions are individually generated by a plurality of ion generating elements and are independently emitted into a room.
The ion generating element and the ion generating device of the present invention are mainly used in various electric appliances such as air conditioners, dehumidifiers, humidifiers, air purifiers, refrigerators, fan heaters, microwave ovens, washing and drying machines, dust collectors, and sterilizers used in enclosed spaces (rooms in home, buildings, hospital wards and operating rooms, vehicles, airplanes, ships, warehouses, and refrigerators).
