Description

  The present invention relates to an ion generating apparatus and an ion generating method for generating positive ions and negative ions and releasing them into the air.

  In recent years, ion generators that generate ions by discharge and discharge them into the air have become widespread, and the related art related thereto is disclosed in Patent Document 1.

  The conventional ion generator described in Patent Document 1 includes a housing, two casings formed in the housing, two ducts connected to one of the two casings and communicating with the casings. It has. Each of the two casings and the duct communicates a suction port that opens to the lower side surface and a blower port that opens to the upper surface.

  A motor is disposed between the two casings, and a common output shaft of the motor projects toward each casing. The common output shaft is connected to an impeller disposed inside each of the two casings to form a sirocco fan. When the motor is driven, the impeller rotates and airflow flows through each of the two communicating casings and ducts.

  An ion generator is disposed in each of the two ducts. The ion generator includes a positive ion generator to which a positive high voltage is applied and a negative ion generator to which a negative high voltage is applied. Positive ions composed of air ions are generated by the discharge in the positive ion generator, and negative ions composed of air ions are generated by the discharge in the negative ion generator.

  And this ion generator is equipped with the turntable below the housing, and the housing is installed on the table of the turntable upper part. The table is formed flat and rotates about a rotation axis extending in the vertical direction. That is, the ion generator can rotate the entire housing in a horizontal plane around a rotation axis extending in the vertical direction.

  The conventional ion generator is installed on, for example, an indoor floor, and indoor air is taken into the two casings through the suction port by driving a sirocco fan. The taken-in air contains positive ions and negative ions generated by the ion generator, and is discharged into the room from the outlet on the upper surface of the housing. And the air in which ion is contained by the drive of a turntable is discharge | released indoors from the blower outlet which rotates in a horizontal surface. Airborne bacteria and odor components in the air can be destroyed by positive ions and negative ions released from the outlet, and indoor sterilization and deodorization can be performed.

JP 2010-266139 A

  However, since the conventional ion generator includes both positive ions and negative ions in the air flowing through each of the two ducts, the positive ions and the negative ions collide with each other while flowing through the duct. For this reason, there was a problem that neutralization deactivation in which ions disappear due to collision occurs, the amount of released ions is reduced, and the effect of sterilization and deodorization in the room cannot be obtained sufficiently. Moreover, when positive ions and negative ions are completely separated and released, an unbalanced region of positive ions and negative ions is generated in the room.

  The present invention has been made in view of the above points, and can generate positive ions and negative ions that can increase the amount of positive ions and negative ions to be released uniformly over a wide range in a room. An object is to provide an apparatus and an ion generation method.

The positive ions generated from the positive ion generator by the discharge of the positive discharge electrode are included in the airflow flowing through the positive ion blower duct and discharged into the room from the positive ion outlet. Negative ions generated from the negative ion generator by the discharge of the negative discharge electrode are included in the airflow flowing through the negative ion blower duct, and are discharged into the room from the negative ion outlet. The positive ions and negative ions released from the positive ion outlet and the negative ion outlet which are displaced so as to turn each other in a different direction by driving the displacement motor cause floating bacteria and odor components in the room. It is destroyed and sterilized and deodorized.

  Further, in the ion generating apparatus having the above-described configuration, the plurality of pairs of the positive ion outlet and the negative ion outlet are provided in pairs, and the plurality of sets are arranged on a circle centering on the rotation axis of the casing. The positive ion outlet and the negative ion outlet are alternately arranged.

  According to this configuration, the casing is rotated by driving the displacement motor, and positive ions and negative ions are released one after another from the plurality of pairs of positive ion outlets and negative ion outlets. The release amount of positive ions and negative ions is further increased.

  Moreover, in the ion generator of the said structure, the said positive ion blower outlet and the said negative ion blower outlet face the mutually opposite direction, It is characterized by the above-mentioned.

  According to this structure, the positive ion discharge | released from the blower outlet for positive ions and the negative ion discharge | released from the blower outlet for negative ions are discharge | released toward a mutually opposing direction. Opportunities of positive ions and negative ions colliding are reduced, and the amount of positive ions and negative ions emitted is further increased.

  Moreover, in order to solve said subject, the ion generating method of this invention distribute | circulates the air flow containing a positive ion and the air flow containing a negative ion separately to two ventilation ducts, the air flow containing a positive ion, and a negative ion The positions of the air outlet containing positive ions for discharging air current containing positive ions and the air outlet for negative ions releasing air current containing negative ions are discharged from the air duct in different directions. The positive ion outlet and the negative ion outlet are displaced so as to be interchanged.

  According to this method, the air stream containing positive ions and the air stream containing negative ions are separately circulated and released in different directions. The positive ions and negative ions released from the positive ion outlet and the negative ion outlet, which are displaced so as to change their positions, destroy the floating bacteria and odor components in the room, and sterilize and deodorize.

  According to the configuration of the present invention, the positive ion generator is disposed in the positive ion air duct and the negative ion generator is disposed in the negative ion air duct, and the positive ion outlet and the negative ion outlet are mutually connected. Since they are directed in different directions, neutralization deactivation due to collision between positive ions and negative ions can be reduced. Further, since the positive ion outlet and the negative ion outlet are displaced so as to replace the positions of the positive ion outlet and the negative ion outlet, the positive ions and the negative ions can be discharged into the room in a well-balanced manner. . Therefore, it is possible to provide an ion generation apparatus and an ion generation method capable of increasing the amount of positive ions and negative ions to be emitted and uniformly releasing positive ions and negative ions over a wide range in the room.

  The blower fan 4 is disposed in the positive ion blow duct 10 and the negative ion blow duct 20. The blower fan 4 is composed of, for example, a sirocco fan, and two impellers 4b and 4c driven by a common fan motor 4a are provided coaxially. The impeller 4b is arranged in the air duct 10 for positive ions with an air inlet (not shown) facing the air inlet 11 for positive ions. The impeller 4c is arranged in the negative ion air duct 20 with an intake port (not shown) facing the negative ion suction port 21. When the impellers 4b and 4c are rotated by the fan motor 4a, the airflow flows through the positive ion air duct 10 and the negative ion air duct 20. In the present embodiment, the blower fan 4 is a sirocco fan, but it may be a propeller fan or a turbofan fan.

  As shown in FIGS. 2 and 3, the ion generator 30 is disposed downstream of the blower fan 4 in the air flow direction and below the positive ion outlet 12 and the negative ion outlet 22. The ion generator 30 is provided with a discharge electrode 31 used for discharge for discharging ions and other electronic components in a housing, and is packaged, for example, as shown in FIG.

  The ion generator 30 includes a pair of positive discharge electrode 31P and negative discharge electrode 31N facing the air duct 10 for positive ions and the air duct 20 for negative ions. The ion generator 30 includes positive ions and negative ions generated by discharge at the positive discharge electrode 31P and the negative discharge electrode 31N with respect to the air flowing through the positive ion blow duct 10 and the negative ion blow duct 20. So as to release them.

  For example, the ion generator 30 includes a circuit shown in FIG. The ion generator 30 includes a circuit unit 32, a positive ion generation unit 33P, and a negative ion generation unit 33N. The circuit unit 32 includes a high-voltage electricity generation circuit that generates a high-voltage electric pulse by receiving power supply from the outside.

  The positive ion generator 33P includes a positive discharge electrode 31P and a positive induction electrode 34P, and the negative ion generator 33N includes a negative discharge electrode 31N and a negative induction electrode 34N. The positive discharge electrode 31P and the negative discharge electrode 31N are each formed in a needle shape and are arranged side by side at a predetermined interval. The positive induction electrode 34P is formed in an annular shape centering on the positive discharge electrode 31P and faces the positive discharge electrode 31P. Similarly, the negative induction electrode 34N is formed in an annular shape centering on the negative discharge electrode 31N and faces the negative discharge electrode 31N.

  Both the positive ion generator 33P and the negative ion generator 33N have the same structure. The positive discharge electrode 31P and the negative discharge electrode 31N are supplied with the high voltage generated by the high-voltage electricity generator circuit, respectively. A discharge is generated between the negative induction electrode 34N and ions are emitted.

Here, a voltage having an AC waveform or an impulse waveform is applied to the positive discharge electrode 31P and the negative discharge electrode 31N of the ion generator 30. A positive voltage is applied to the positive discharge electrode 31P, and hydrogen ions generated by corona discharge combine with moisture in the air to generate positive ions mainly composed of H ⁺ (H ₂ O) m. A negative voltage is applied to the negative discharge electrode 31N, and oxygen ions generated by corona discharge combine with moisture in the air to generate negative ions mainly composed of O ₂ ⁻ (H ₂ O) n. Here, m and n are arbitrary natural numbers. H ⁺ (H ₂ O) m and O ₂ ⁻ (H ₂ O) n aggregate on the surface of airborne bacteria and odorous components and surround them.

Then, as shown in the formulas (1) to (3), the active species [.OH] (hydroxyl radical) and H ₂ O ₂ (hydrogen peroxide) are aggregated and formed on the surface of the microorganism or the like by collision. Destroy airborne bacteria and odorous components. Here, m ′ and n ′ are arbitrary natural numbers. Accordingly, by generating positive ions in the positive ion air duct 10 and releasing them from the positive ion blower outlet 12, and generating negative ions in the negative ion air duct 20 and releasing them from the negative ion air outlet 22, For example, indoor sterilization and deodorization can be performed.

_{^{H + (H 2 O) m}} + H + (H 2 O) m '+ O 2 - (H 2 O) n + O 2 - (H 2 O) n'
→ 2 OH + O ₂ + (m + m ′ + n + n ′) H ₂ O (2)
_{^{H + (H 2 O) m}} + H + (H 2 O) m '+ O 2 - (H 2 O) n + O 2 - (H 2 O) n'
→ H ₂ O ₂ + O ₂ + (m + m ′ + n + n ′) H ₂ O (3)

  In this embodiment, positive ions and negative ions are generated by the ion generator 30, but only positive ions or only negative ions may be generated.

  In the present invention, the ion includes charged fine particle water. At this time, the ion generator 30 consists of an electrostatic atomizer, and the charged fine particle water containing a radical component is produced | generated by the electrostatic atomizer. That is, condensation water is generated on the surface of the discharge electrode by cooling the discharge electrode provided in the electrostatic atomizer by the Peltier element. Next, when a negative high voltage is applied to the discharge electrode, charged fine particle water is generated from the dew condensation water. Further, negative ions released into the air together with the charged fine particle water are also generated from the discharge electrode.

  The pedestal 3 is provided below the main body housing 2 in order to enable the ion generator 1 to rotate. As shown in FIGS. 2 and 3, the pedestal portion 3 includes a rotary table portion 3a, a base portion 3b, a displacement motor 3c and a gear mechanism 3d provided in the base portion 3b.

  A rotary table portion 3a having a circular shape in plan view is rotatably supported on a base portion 3b having a circular shape in plan view installed on the floor surface. The rotary table portion 3a rotates in a horizontal plane around the axis of a rotary shaft 3e that is arranged at the center in the radial direction and extends in the vertical direction. The upper surface of the rotary table portion 3a is flat and supports the main body housing 2.

  The rotary table 3a is connected to a displacement motor 3c through a gear mechanism 3d. When the ion generator 1 drives the displacement motor 3c, the ion generator 1 realizes a rotating operation of rotating the main body housing 2 around the rotation shaft 3e. Thereby, the main body housing | casing 2 rotates so that the position of the blower outlet 12 for positive ions and the blower outlet 22 for negative ions may be replaced.

  When the operation switch (not shown) is operated in the ion generator 1 having the above configuration to instruct the air blowing operation, the air blowing fan 4, the ion generator 30, and the displacement motor 3c are driven. As a result, the body housing 2 sucks the air inside the ion generator 1 outside the positive ion air duct 10 and the negative ion air duct 20 through the positive ion air inlet 11 and the negative ion air inlet 21. Dust contained in the air is collected by the dust collection filters 13 and 23.

  The positive ion generated by the positive ion generator 33P is included in the air that flows through the positive ion air duct 10 after removing dust, and is discharged from the positive ion outlet 12. The negative ions generated by the negative ion generator 33N are contained in the air that flows through the negative ion blowing duct 20 after removing the dust, and is discharged from the negative ion outlet 22. Since the positive ion outlet 12 and the negative ion outlet 22 are directed in different directions, positive ions and negative ions are emitted in different directions.

  In addition, the pedestal 3 having the displacement motor 3 c starts rotating the main body housing 2 in accordance with the operation of the blower fan 4. Thereby, air containing positive ions and negative ions is released while rotating in a horizontal plane around the axis of the rotation shaft 3e so that the positive ion outlet 12 and the negative ion outlet 22 are interchanged with each other. . Accordingly, positive ions and negative ions flow separately from the positive ion blower duct 10 and the negative ion blower duct 20, and rotate from the rotating positive ion outlet 12 and the negative ion outlet 22 in different directions. Therefore, the neutralization inactivation of ions can be reduced to increase the delivery amount, and the ions can be released in a well-balanced manner.

  Then, airborne bacteria and odor components in the air are destroyed by the positive ions released from the positive ion outlet 12 and the negative ions released from the negative ion outlet 22 to sterilize and deodorize the room.

  Subsequently, the measurement results of the ion concentration in the room when the ion generator 1 having the above configuration is driven will be described with reference to FIGS. FIG. 6 is an explanatory view showing the time change of the ion concentration at a predetermined measurement point in the room by the ion generator 1, and FIG. 7 is an explanatory view showing the measurement result of the number of ions at the six measurement points in the room by the ion generator 1. FIG. 8 is an explanatory diagram showing a change in ion concentration with time when the main body displacement rotational speed of the ion generator 1 is changed, and FIG. 9 is an explanatory diagram showing comparison of ion concentrations when the main body displacement rotational speed of the ion generator 1 is changed. FIG.

Here, the conventional apparatus used as the comparison object of the ion generator 1 of the said structure is demonstrated. The conventional apparatus of the ion generator 1 includes a single air duct, and has a structure in which both positive ions and negative ions are included in the air flowing through the air duct. And the conventional apparatus discharge | releases the air containing both a positive ion and a negative ion in a room | chamber interior from each of the two outlets provided in the upper surface. During the experiment, one conventional apparatus was placed in the center of the room and was driven with an air volume of 1.5 m ³ / min.

First, one ion generator 1 was placed in the center of the room, and was driven at a rotational speed of 15 rpm for rotating the main body housing 2 and an air volume of 1.5 m ³ / min. The time change of the ion concentration at a predetermined measurement point in the room at this time is shown in FIG. In FIG. 6, the horizontal axis represents time, the vertical axis represents ion concentration, and the solid line waveform represents time variation of the ion concentration at the measurement point. According to FIG. 6, it can be seen that the ion concentration increases and decreases in synchronization with the rotation of the main body housing 2 at 15 rpm.

  FIG. 7 shows the measurement results of the number of ions at six measurement points in the room. FIG. 7 shows how many times the number of positive ions and the number of negative ions is increased as compared with the conventional apparatus. According to FIG. 7, it can be seen that the ion concentrations at all six measurement points in the room are increased, and on average, increased by 2.83 times compared to the conventional case.

  Next, the main body housing 2 of the ion generator 1 was driven by changing the number of rotations to 10 rpm, 15 rpm, and 30 rpm. The time change of the ion concentration at the predetermined measurement point in the room at this time is shown in FIG. In FIG. 8, the horizontal axis represents time, the vertical axis represents ion concentration, and the time variation of the ion concentration at the measurement point when the three types of waveforms are at each rotation number is shown. According to FIG. 8, it can be seen that the ion concentration increases and decreases in synchronization with the rotation of the main body housing 2 at 10 rpm (short broken line waveform), 15 rpm (solid line waveform), and 30 rpm (long broken line waveform).

  And the comparison result of the ion concentration when changing the rotation speed which rotationally displaces the main body housing | casing 2 is shown in FIG. FIG. 9 describes how many times the ion concentration is higher than that of the conventional apparatus as a conventional ratio. According to FIG. 9, it can be seen that the ion concentration at 15 rpm is increased 6.12 times compared to the conventional one, and is the highest ion concentration compared to 10 rpm and 30 rpm.

  As described above, the ion generator 1 includes the positive ion blower duct 10 having the positive ion outlet 12 and the positive ion generator 33P, and the negative ion blower having the negative ion outlet 22 and the negative ion generator 33N. A duct 20 and a displacement motor 3c that rotates the main body housing 2 so as to exchange positions of the positive ion outlet 12 and the negative ion outlet 22 that are directed in different directions are provided. Thereby, the positive ion blower outlet 12 and the negative ion blower outlet 22 are alternately directed to a certain point in the room, and positive ions and negative ions arrive at a constant time interval. Therefore, positive ions and negative ions can be released and diffused into the room with good balance. In addition, since positive ions and negative ions are diffused at the same position until one ion is released at the same position, the other ions previously discharged are diffused. It is possible to reduce. Then, floating bacteria and odor components in the room can be destroyed by positive ions and negative ions, and sterilization and deodorization can be performed.

  Further, since the positive ion outlet 12 and the negative ion outlet 22 face in opposite directions, the positive ions discharged from the positive ion outlet 12 and the negative ions discharged from the negative ion outlet 22 are provided. Ions are emitted in opposite directions. Therefore, the chance of positive ions and negative ions colliding decreases, and the amount of positive ions and negative ions emitted can be further increased.
