Description

Ion generator

This invention relates to the ion generator which discharge | releases positive / negative ion in the air and performs disinfection and deodorization indoors.

Many houses built in recent years have become highly airtight, and pollutants that have been generated or have flowed into the room are likely to stay in the room. The problem of developing etc. is getting serious. Therefore, the demand for air purifiers and air conditioners with an ion generation function is increasing. As for air purification, not only let it pass through a filter, but also advanced techniques such as using an electrostatic precipitator or adding ions or ozone have come to be used.

As shown in FIG. 7, the air cleaner described in Patent Document 1 includes a lateral outlet 205 provided on the side surface of the main body 203 and a front outlet 206 provided on the front surface of the main body 203. . The front outlet 206 is provided with an ionization means 209 including a needle-like discharge electrode 207 and a counter electrode 208 facing the discharge electrode 207. By generating negative ions by the ionization means 209 and releasing them from the front outlet 206, the dust in the room is negatively charged. The negatively charged dust is attracted and collected by a positive dust collecting electrode provided at the suction port of the air cleaner.

Patent Document 2 proposes a sterilization / deodorization device that generates positive ions and negative ions to sterilize bacteria floating in the air and deodorize air. As shown in FIG. 8, the sterilizing / deodorizing apparatus includes a positive ion generating unit 301 for generating positive ions and a negative ion generating unit 302 for generating negative ions, and positive ions and negative ions are provided separately from each. It is discharged to the outside through the

ducts

303 and 304 formed. According to the sterilization / deodorization apparatus of Patent Document 2, the released positive ions and negative ions adhere to airborne bacteria and odor components, thereby generating H ₂ O ₂ or OH radicals, which are suspended in the air. Bactericidal action or deodorizing action can be obtained by oxidizing bacteria and odor components.

However, only the negative ions are discharged from the air cleaner of Patent Document 1, and only dust in the air is charged by the negative ions and collected on the positive dust collecting electrode.

Also, as in the sterilization / deodorization apparatus of Patent Document 2, when positive ions and negative ions are released to the outside, there is a problem that it is difficult to supply positive ions and negative ions in a well-balanced manner to every corner of the room.

That is, the positive ions and the negative ions blown in the same direction from the

respective ducts

303 and 304 are prevented from moving in the diffusion direction with respect to the blowing direction by the electric attractive force acting between them. For this reason, a phenomenon occurs in which the ion concentration increases in each air flow direction of positive ions and negative ions, and the ion concentration decreases in the vicinity thereof, and as a result, it cannot be supplied in a well-balanced manner to every corner of the room.

The present invention has been made in view of the current situation as described above, and the object thereof is to supply positive ions and negative ions in a well-balanced manner to every corner of the room and to obtain an excellent bactericidal action and deodorizing action. An ion generator is provided.

The ion generator of the present invention includes positive ion generating means for generating positive ions, negative ion generating means for generating negative ions, a first outlet for discharging positive ions, and a second outlet for discharging negative ions. The ion generator is characterized in that a first louver and a second louver that change the blowing direction are provided in the first blowout port and the second blowout port, respectively.

Further, the first louver and the second louver are switched between a first mode in which the blowing directions are substantially parallel and a second mode in which the blowing directions are a predetermined opening angle.

In addition, the first louver and the second louver are driven to swing left and right or up and down in the first mode.

In addition, the first louver and the second louver continuously change between the first mode and the second mode.

The first air outlet and the second air outlet are connected to the separated air passages, and the positive ion generating means and the negative ion generating means are provided separately in the separated air passages.

In addition, the ion generator includes positive ion generating means for generating positive ions, negative ion generating means for generating negative ions, a first outlet for releasing positive ions, and a second outlet for releasing negative ions. The blowing direction of the 1st blower outlet and the 2nd blower outlet has separated.

According to the present invention, positive ions and negative ions can be supplied in a well-balanced manner to every corner of the room.

Embodiment 1

FIG. 1 is a perspective view of an ion generator 1 of the present invention. The ion generator 1 of the present invention can be used for an air purifier, a static eliminator, and the like. A first outlet 11 that blows out clean air containing positive ions to the front of a housing 10 and negative ions. The second blower outlet 12 that blows out clean air containing air, the operation panel unit 13 for operating the ion generator 1, and the operation display unit 14 that displays the operation status of the ion generator 1 are provided.

FIG. 2 is a cross-sectional view showing the inside of the ion generator 1, and shows a cross section taken along line AA shown in FIG. As shown in FIG. 2, a suction port 15 for taking in indoor air is provided on one wall surface of the ion generator 1 and on the opposite surface side of the first air outlet 11 and the second air outlet 12. The suction port 15 is provided with a filter unit 16 that captures dust in the air.

Inside the ion generator 1, there is provided an air passage 17 composed of a main air passage 17a and

auxiliary air passages

17b and 17c. The main air passage 17a is connected to the suction port 15, and the auxiliary air passage 17b and the auxiliary air passage are provided. 17c is connected to the 1st blower outlet 11 and the 2nd blower outlet 12, respectively, and between the 1st blower outlet 11 and the 2nd blower outlet 12 is connected by the air path 17 from the suction inlet 15. FIG.

Inside the main air passage 17a, a blower 18 for blowing clean air from which dust or the like has been removed by the filter unit 16 toward the first air outlet 11 and the second air outlet 12 is provided. Further, the secondary air passage 17b is provided with positive ion generating means 21 for generating positive ions, and the auxiliary air passage 17c is provided with negative ion generating means 22 for generating negative ions. Since the positive ion generating means 21 and the negative ion generating means 22 are separately provided in each of the auxiliary air passage 17b and the auxiliary air passage 17c, the positive ions and the negative ions are mixed inside the air passage 17. It is prevented from being summed.

The positive ion generation means 21 and the negative ion generation means 22 have a configuration in which needle-like discharge electrodes and ring-like counter electrodes are arranged at a predetermined interval, and apply a positive or negative high voltage to the discharge electrodes. Thus, positive ions or negative ions are generated. These positive ion generating means 21 and negative ion generating means 22 are controlled so as to generate the same amount of ions.

The ion generator 1 of the present invention varies the blowing direction of each ion in the vicinity of the first air outlet 11 and the second air outlet 12 in the auxiliary air passage 17b and the auxiliary air passage 17c in the above configuration. The first louver 19 and the second louver 20 are provided. The first louver 19 and the second louver 20 are each composed of a plurality of wind direction plates that change their directions in conjunction with each other, and the first louver 19 and the second louver 20 are driven by a driving mechanism (not shown), thereby The direction of positive ions 31 blown from the blower outlet 11 and the direction of negative ions 32 blown from the second blower outlet 12 can be changed separately.

FIG. 3 is a schematic diagram for explaining conditions when the ion concentration distribution in the indoor space by the ion generator 1 is simulated, and is equivalent to 6 tatami mats (Y axis (depth) × X axis (width) × Z axis ( A top view (a) and a side view (b) in a state in which the ion generator 1 is disposed in the indoor space 40 (height) = 3.5 m × 3.0 m × 2.5 m) and an evaluation location of ion concentration The front view (c) of the predetermined distance from the ion generator 1 is shown. In addition, the inside space 40 is 1 atm and 30 ° C., and the ion generator 1 sets the distance d0 = 30 cm between the first air outlet 11 and the second air outlet 12, and positive ions 31 with an ion current of 400 nA from each of them. The negative ions 32 are set to blow out at a wind speed of 3 m / s.

Then, the blowing direction of the first blower outlet 11 and the second blower outlet 12 of the ion generator 1 is changed from 0 degree which is parallel to an opening angle 35 of 15 degrees, 30 degrees, 60 degrees and 90 degrees, The ion concentration distribution in the opposite plane at a distance of D = 2.5 m from the ion generator 1 was examined.

FIG. 4 shows an in-plane distribution diagram of ion concentrations of positive ions and negative ions as a simulation result.

As a first mode for controlling the blowing direction of the ion generator 1, if the blowing direction of the positive ions 31 and the blowing direction of the negative ions 32 are parallel (opening angle = 0 degree), which is the positive ion concentration or the negative ion concentration? Also, it is intensively increased at the point P5 facing the blowing direction, and a difference of about 20 times is generated as compared with the point where the ion concentration is the lowest, and the in-plane distribution of ions is increased.

This is considered to be because if the positive ions 31 and the negative ions 32 are blown out in the same direction, they attract each other due to the electric attractive force, so that it is difficult to diffuse outside the blowing direction. Here, the fact that the in-plane distribution of ions is large means that the ion concentration difference in the plane is large, and that the in-plane distribution of ions is small means that the ion concentration difference in the plane is small. Yes.

On the other hand, as the second mode of the ion generator 1, when the opening angle 35 is increased with the blowing direction of the positive ions 31 and the blowing direction of the negative ions 32 outward, the spots where the ions concentrate are divided into two locations. When the opening angle is 60 degrees, the ion concentration at the spot where the ions are concentrated decreases slightly, but the ion concentration at the spot where the ion concentration around the spot is small increases more than twice. It can be seen that the difference between the maximum value and the minimum value of the concentration is reduced, and variation in the distribution of the ion concentration can be improved. This is because the spot where the ion concentration concentrates follows each blowing direction, and the positive ions 31 and the negative ions 32 are blown in different directions, so that the electrical attractive force becomes weak and the blowing direction. It is thought that it becomes easy to diffuse also outside.

For this reason, according to the magnitude | size of the indoor space 40, the indoor distribution of ion can be made uniform by setting appropriately the opening angle of the blowing direction of the positive ion 31 and the blowing direction of the negative ion 32, Positive ions and negative ions can be supplied to every corner of the room in a well-balanced manner.

FIG. 5 is a top view for explaining a configuration of swing drive that continuously switches the blowing direction to different directions, and FIG. 5A is a swing that switches the blowing direction of plus ions and minus ions to the left and right directions in the first mode. (B) shows swing drive in which the blowing direction is alternately switched between the first mode and the second mode.

When the local ion effect is expected, it can be used in the first mode in which the blowing direction of the positive ions 31 and the blowing direction of the negative ions 32 are parallel (opening angle = 0 degree). However, as shown in FIG. 5 (a), if the blowing directions that are in parallel are swing-driven in the left-right direction or the up-down direction, the variation in the ion concentration distribution can be improved throughout the room. Negative ions can be supplied to every corner of the room in a well-balanced manner.

Moreover, in the ion generator 1, as shown in FIG.5 (b), the blowing direction is between the 1st mode from which each blowing direction becomes parallel, and the 2nd mode in which each blowing direction has an opening angle. It may change continuously. By continuously changing the blowing direction in this way, it is possible to secure a certain level of ion concentration throughout the room while increasing the ion concentration at a specific location.

Therefore, according to the ion generator 1 of the present invention, positive ions and negative ions can be supplied into the room with good balance. In addition, each ion is attached to airborne bacteria and odor components to generate H ₂ O ₂ or OH radicals, and the airborne bacteria and odor components are oxidized to obtain bactericidal and deodorizing effects. be able to.
[Embodiment 2]

FIG. 6 is a side view of the ion generator 2 according to the second embodiment. The difference from the ion generator 1 shown in Embodiment 1 is that the positive ion first air outlet 11 and the negative ion second air outlet 12 are arranged in the vertical direction of the ion generator 2. Since the configuration is the same, detailed description is omitted.

The ion generator 2 in FIG. 6A is a first mode configuration in which the blowing direction of the positive ions 31 and the blowing direction of the negative ions 32 are parallel to each other, as in the first embodiment. By swinging the blowing direction left and right or up and down, variation in ion concentration distribution can be improved throughout the room, and positive ions and negative ions can be supplied to every corner of the room in a well-balanced manner.

The ion generator 2 in FIG. 6B is in the second mode in which an opening angle is provided between the blowing direction of the positive ions 31 and the blowing direction of the negative ions 32, and the positive ions are the same as in the first embodiment. By appropriately setting the opening angle between the blowing direction of 31 and the blowing direction of the negative ions 32, variation in ion concentration distribution can be improved throughout the room.

Moreover, while increasing the ion concentration of a specific location by swinging the blowing direction between the first mode in which each blowing direction is parallel and the second mode in which each blowing direction has an opening angle, A certain level of ion concentration can be ensured throughout the room. Positive ions and negative ions can be supplied to every corner of the room in a well-balanced manner.

Further, when the ion generator 1 is used while being placed on the floor surface, as shown in FIG. 6 (c), the blowing direction is set parallel to the floor surface from the lower outlet, and from the upper outlet. It is preferable to provide an opening angle by opening the blowing direction. Such a setting prevents ions blown out from the lower outlet from being directly adsorbed to the floor surface and not being supplied to the room, and an appropriate opening angle 35 is set in the blowing direction of positive ions and negative ions. It can be provided, and variation in ion concentration distribution can be improved throughout the room. Further, the upper blowing direction may be swing-driven.

Further, in the above-described embodiment, the case where both the first air outlet 11 and the second air outlet 12 are variable is illustrated, but at least one of the air outlets can be swing-driven, and the other air outlet can be fixed. good.

Moreover, although the 1st louver 19 was provided in the 1st blower outlet 11 and the 2nd louver 20 was provided in the 2nd blower outlet 12 in embodiment mentioned above, the structure which can vary each blowing direction was illustrated. May be fixed by inclining the wall surfaces of the auxiliary air passage 17b and the auxiliary air passage 17c of the air passage 17 so as to be separated from each other.

The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
