Description

Ion generator

The invention relates to an ion generating device.

Ion generating devices that supply ions to indoor air are popular. In addition, various techniques for efficiently supplying ions to indoor air are disclosed in the ion generating device.

For example, the ion generating device described in Patent Literature 1 includes a main body case, an air blowing path, and an ion generator. The supply air path is formed in the body casing. The supply air path includes a blow-out port. The ion generator is arranged at the narrowest position of the air supply path. The ion generator generates ions. Ions are discharged from the outlet to the outside of the ion generating device.

Patent Document 1: Japanese Patent Laid-Open No. 2010-287321.

In the ion generating device described in Patent Document 1, since the ion generator is arranged at the narrowest position of the air blowing path, the amount of ions contained in the air can be increased. That is, in the narrowest position, since the speed of air flow is fast, the generated ions are sent out to the outlet in a short time. Therefore, the positive ions and negative ions are not neutralized until they are delivered to the delivery outlet. Therefore, it is possible to maintain the high ion concentration and send it to the outside of the ion generating device. However, the above-mentioned ion generation device has room for improvement in increasing the amount of ions contained in the air.

In view of the above-mentioned problems, the present invention aims to provide an ion generating device that can increase the amount of ions contained in air.

The ion generating device of the present invention includes a discharger, an air supply duct, and a supporting member. The discharger generates a discharge factor. The discharge factor includes at least one of positive ions and negative ions. The blowing air path sends out the air containing the discharge factor to the outside of the ion generating device. The support member is fixed to the wall surface of the air supply duct. The supporting member supports the discharger so that the discharger protrudes toward the central portion of the blowing air passage. The width of the support member in the first direction is narrower than the width of the wall surface of the air blowing duct on which the support member is arranged in the first direction. The first direction indicates a direction substantially perpendicular to the air sending direction and parallel to the wall surface of the air blowing path.

According to the ion generating apparatus of the present invention, the amount of ions contained in air can be increased.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings (FIGS. 1 to 6 ). In addition, in the drawings, the same or corresponding parts are given the same reference symbols, and descriptions are not repeated.

First, referring to FIG. 1, the configuration of the air cleaning device 100 according to the embodiment of the present invention will be described. FIG. 1 is a side view showing an example of the structure of the air cleaning device 100. As shown in FIG. 1, the air cleaning device 100 includes a first unit 100A, a second unit 100B, and a leg 112. The air cleaning device 100 corresponds to an example of "ion generating device".

Moreover, in the embodiment of the present invention, the X axis, the Y axis, and the Z axis that are perpendicular to each other are shown in the figure. The Z axis is parallel to the vertical direction, and the X axis and Y axis are parallel to the horizontal direction. The negative direction of the X axis indicates the front side of the air cleaning device 100.

The first unit 100A is arranged on the positive X-axis side of the air cleaning device 100. That is, the first unit 100A is arranged on the back side of the air cleaning device 100. The second unit 100B is arranged on the negative side of the X axis of the air cleaning device 100. That is, the second unit 100B is arranged on the front side of the air cleaning device 100. The leg portion 112 is arranged below the first unit 100A and the second unit 100B. The leg portion 112 supports the first unit 100A and the second unit 100B.

The first unit 100A includes a back panel 110, a motor 132, a fan 130, a flow path forming member 123, a duct 3, an ion generating section 2, and an exhaust port 29.

The back panel 110 is arranged on the back side of the first unit 100A. That is, the rear panel 110 is disposed on the positive side of the X axis of the first unit 100A. The back panel 110 supports the motor 132 and the fan 130.

The motor 132 rotationally drives the fan 130. The motor 132 is arranged between the fan 130 and the back panel 110.

The fan 130 generates a flow of air. Specifically, the fan 130 sucks the air in the second unit 110B as shown in the direction D, and sequentially discharges it from the discharge port 29 to the outside of the air cleaning device 100 through the flow path forming member 3 and the duct 3 air. The direction D indicates the direction of air flow.

The flow path forming member 123 guides the air discharged by the fan 130 toward the duct 3.

The duct 3 allows the air discharged by the fan 130 to flow toward the discharge port 29. The duct 3 corresponds to an example of "air supply air path". The flow path forming member 123 and the pipe 3 will be described in detail later with reference to FIG. 2.

The ion generator 2 includes an ion generator 21 and a rib 22. The ion generator 21 generates ions. The ion generator 21 will be described in detail later with reference to FIGS. 5 and 6.

The rib 22 is formed to stand upright on the rear panel 110 and protrude toward the inside of the duct 3. The rib 22 corresponds to an example of "plate-shaped member". The rib 22 will be described in detail later with reference to FIGS. 2 and 3.

The discharge port 29 is formed in the upper part of the air cleaning device 100 and discharges air containing ions to the outside of the air cleaning device 100.

The second unit 100B includes a front panel 140, a filter 151, a frame 150, and a partition wall 120. The front panel 140 covers the front of the second unit 100B.

The filter 151 includes a deodorizing filter 152, a formaldehyde adsorption filter 153, and a dust suction filter 154. Each of the deodorizing filter 152, the formaldehyde adsorption filter 153, and the dust suction filter 154 is formed in a flat plate shape. The frame 150 fixes the filter 151 in the second unit 100B. Specifically, the main surface of the filter 151 is fixed so as to be parallel to the Y-Z plane.

The deodorizing filter 152, the formaldehyde adsorption filter 153, and the dust suction filter 154 are sequentially stacked in the X-axis direction from the front side. The deodorizing filter 152 deodorizes the air. The formaldehyde adsorption filter 153 adsorbs formaldehyde in the air. The dust suction filter 154 adsorbs dust in the air.

The partition wall 120 is arranged on the back side of the second unit 100B. The partition wall 120 includes a communication hole 121. The communication hole 121 sends out the air in the second unit 100B into the first unit 100A. Specifically, as shown in the direction D, the communication hole 121 sequentially sends the air flowing into the second unit 100B from the outside of the air cleaning device 100 through the front panel 140 and the filter 151 into the first unit 100A.

Next, the flow of air will be described. The fan 130 draws air from the outside of the air cleaning device 100 as shown in the direction D. The air sucked from the outside flows into the fan 130 through the front panel 140, the filter 151, and the communication hole 121 in this order as shown in the direction D. In addition, the air discharged by the fan 130 is discharged from the discharge port 29 to the outside of the air cleaning device 100 through the duct 3 as shown in the direction D.

Next, the configuration of the air cleaning device 100 according to the embodiment of the present invention will be described with reference to FIGS. 1 to 3. FIG. 2 is a front view showing an example of the configuration of the first unit 100A. FIG. 2 is a front view of the air cleaning device 100. FIG. 3 is an enlarged front view showing an example of the configuration of the first unit 100A.

As shown in FIGS. 2 and 3, the flow path forming member 123 is formed in an arc shape. Specifically, the center of the flow path forming member 123 is eccentric with respect to the central axis of the motor 132 in the positive direction of the Y axis and in the negative direction of the Z axis. That is, the flow path forming member 123 is formed so that the width W of the flow path of the air discharged from the fan 130 becomes wider toward the downstream in the direction D. The width W is the distance between the outer periphery of the fan 130 and the flow path forming member 123.

In addition, the first unit 100A further includes a first wall member 25 and a second wall member 26. As shown in FIG. 3, the ion generating unit 2 further includes a support member 210, a first inclined member 23, and a second inclined member 24.

The support member 210 is fixed to the wall surface of the pipe 3. The support member 210 supports the ion generator 21 so that the ion generator 21 protrudes toward the center of the pipe 3. Specifically, the support member 210 supports the ion generator 21 such that the ion generator 21 protrudes toward the center of the pipe 3 in the X-axis direction.

The width W1 of the support member 210 in the first direction DR1 is narrower than the width W2 and the width W3 of the wall surface of the pipe 3 to which the support member 210 is fixed in the first direction DR1. The first direction DR1 indicates a direction substantially perpendicular to the direction D and parallel to the wall surface of the duct 3 (part of the rear panel 110). Specifically, the first direction DR1 indicates the Y-axis direction. The width W1 indicates the width of the support member 210 in the first direction DR1. The width W2 is the width in the first direction DR1 representing the wall surface of the duct 3 in the upstream end of the support member 210 in the direction D. The width W3 is the width in the first direction DR1 representing the wall surface of the duct 3 in the downstream end of the support member 210 in the direction D.

The width W1 of the support member 210 in the first direction DR1 is formed substantially the same as the width W4 of the ion generator 21 in the first direction DR1. The width W4 indicates the width of the ion generator 21 in the first direction DR1.

The first inclined member 23 is arranged on the wall surface of the duct 3 (part of the rear panel 110) on the upstream side of the support member 210 in the direction D. The second inclined member 24 is arranged on the wall surface of the duct 3 (part of the rear panel 110) on the downstream side of the support member 210 in the direction D. The first inclined member 23 and the second inclined member 24 will be described in detail later with reference to FIGS. 5 and 6.

The lower end of the first wall member 25 is connected to the upper end of the flow channel forming member 123. The lower end of the second wall member 26 is connected to the upper end of the flow channel forming member 123. The first wall member 25 and the second wall member 26 are arranged to face each other, and form part of the duct 3.

Specifically, the duct 3 is formed by the first wall member 25, the second wall member 26, a part of the partition wall 120 shown in FIG. 1, and a part of the back panel 110. That is, the first wall member 25 constitutes a wall on the positive side of the Y axis in the duct 3, and the second wall member 26 constitutes a wall on the negative side of the Y axis in the duct 3. As shown in FIG. 1, a part of the back panel 110 constitutes a wall on the positive side of the X axis in the duct 3, and a part of the partition wall 120 constitutes a wall on the negative side of the X axis in the duct 3.

In addition, the rib 22 is arranged on the upstream side in the direction D with respect to the ion generator 21. The rib 22 is arranged parallel to the X-Z plane. The air reaching the rib 22 is divided into the direction D1 and the direction D2 and flows out from the discharge port 29. The direction D1 is the direction indicating the first air flow, and the direction D2 is the direction indicating the second air flow.

As shown in the direction D1, the first air flow flows on the negative direction side of the Y axis with respect to the rib 22. In other words, the first air flow flows through the space between the rib 22 and the second wall member 26. The second air flow flows through the positive direction side of the Y axis with respect to the rib 22. In other words, the second air flow flows through the space between the rib 22 and the first wall member 25. The first air flow contains, for example, positive ions, and the second air flow contains, for example, negative ions.

As described above with reference to FIGS. 1 to 3, in the embodiment of the present invention, the support member 210 supports the ion generator 21 so that the ion generator 21 protrudes toward the center of the pipe 3. Therefore, since the ion generator 21 is arranged in the center of the duct 3 with a fast wind speed, the amount of ions contained in the air can be increased. In addition, the width W1 of the support member 210 in the first direction DR1 is narrower than the width W2 and the width W3 of the wall surface of the duct 3 (part of the back panel 110) where the support member 210 is disposed in the first direction DR1. Therefore, it is possible to suppress the support member 210 from obstructing the flow of air in the duct 3. Therefore, the amount of ions contained in the air can be further increased.

In addition, the width W1 of the support member 210 in the first direction DR1 is formed substantially the same as the width W4 of the ion generator 21 in the first direction DR1. Therefore, it is possible to further suppress that the support member 210 obstructs the flow of air in the duct 3. Therefore, the amount of ions contained in the air can be further increased.

The rib 22 is arranged on the upstream side of the direction D with respect to the ion generator 21. In addition, the rib 22 is arranged parallel to the direction D. Therefore, it is possible to suppress neutralization by collision of positive ions and negative ions. Therefore, the amount of ions contained in the air discharged from the discharge port 29 can be further increased.

In addition, in the embodiment of the present invention, although the rib 22 is disposed on the upstream side in the direction D with respect to the ion generator 21, the present invention is not limited to this. For example, the rib 22 may be arranged on the downstream side of the direction D with respect to the ion generator 21.

Next, the configuration of the air cleaning device 100 according to the embodiment of the present invention will be further described with reference to FIGS. 1 to 4. 4 is an IV-IV cross-sectional view showing an example of the configuration of the first unit 100A. The IV-IV section is a plane parallel to the X-Z plane passing through the center of the rib 22 in the thickness direction (Y-axis direction) as shown in FIG. 3.

As shown in FIG. 4, the rib 22 is formed integrally with the back panel 110. In addition, the rib 22 is formed in a rectangular shape. The rib 22 extends along the direction D. The height H1 of the rib 22 is higher than the height H2 of the electrode of the ion generator 21. The height H1 and the height H2 represent heights in a direction away from the rear panel 110. The height H1 is the height in the direction away from the back panel 110 of the rib 22. The height H2 indicates the height away from the back panel 110 of the electrode. The height H2 will be described in detail later with reference to FIG. 6.

As described above with reference to FIGS. 1 to 4, in the embodiment of the present invention, the height H1 of the rib 22 is higher than the height H2 of the electrode of the ion generator 21. Therefore, the rib 22 can divide the air flow from the fan 130 toward the ion generator 21 into a first air flow and a second air flow. Therefore, the amount of ions contained in the air discharged from the discharge port 29 can be further increased.

In addition, the rib 22 extends along the direction D. Therefore, it is possible to further suppress the rib 22 from obstructing the flow of air in the duct 3. Therefore, the amount of ions contained in the air can be further increased.

Next, the configuration of the ion generating unit 2 according to the embodiment of the present invention will be described with reference to FIGS. 1 to 5. FIG. 5 is a front view showing an example of the structure of the ion generating unit 2. As shown in FIG. 5, the ion generator 21 of the ion generator 2 further includes a power supply circuit unit 211, two electrodes 212, and an electrode protection member 213. The ion generator 21 corresponds to an example of "discharger".

The power supply circuit unit 211 applies a voltage between the two electrodes 212 to cause the two electrodes 212 to generate positive ions and negative ions.

Each of the two electrodes 212 is provided upright in the power supply circuit unit 211. In addition, the two electrodes 212 are arranged in the first direction DR1. The first direction DR1 indicates the Y-axis direction. Specifically, the electrode 212a of one of the two electrodes 212 is provided upright at the end of the negative direction side of the Y axis in the power supply circuit unit 211. The electrode 212b of the other of the two electrodes 212 is provided upright at the end of the positive direction side of the Y axis in the power supply circuit unit 211. The electrode 212a generates, for example, positive ions. The electrode 212b generates, for example, negative ions.

The ribs 22 are those in which the air in the duct 3 flows toward the electrode 212a with respect to one side of the rib 22 (the negative side of the Y-axis) and the other side (positive side of the Y-axis) in the duct 3 The air is arranged to flow toward the electrode 212b. The air on one side corresponds to the "first air flow" described with reference to FIGS. 2 and 3. The air on the other side corresponds to the “second air flow” described with reference to FIGS. 2 and 3.

The electrode protection member 213 is arranged on the upstream side and the downstream side of the direction D with respect to the two electrodes 212. The electrode protection member 213 protects the two electrodes 212. Specifically, the electrode protection member 213 protects the electrode 212 so that the user (or other components) does not contact the electrode 212 when manufacturing the air purification device 100 or when repairing the air purification device 100.

As described above with reference to FIGS. 1 to 5, in the embodiment of the present invention, the two electrodes 212 of the ion generator 21 are arranged in the first direction DR1. Therefore, air containing positive ions and air containing negative ions are sent out of the air cleaning device 100. Therefore, the amount of ions contained in the air can be further increased.

In addition, the rib 22 is air flowing toward the electrode 212a with respect to one side of the rib 22 (negative direction side of the Y axis) in the duct 3, and with respect to the other side (positive direction side of the Y axis) of the rib 22 in the duct 3 ) Is arranged so that the air flows toward the electrode 212b. Therefore, it is possible to further suppress the collision of positive ions and negative ions and neutralization. Therefore, the amount of ions contained in the air can be further increased.

In addition, in the embodiment of the present invention, the ion generator 21 generates positive ions and negative ions, but the ion generator 21 may generate a discharge factor. The discharge factor includes at least one of positive ions and negative ions. That is, the ion generator 21 may generate at least one of positive ions and negative ions.

Next, the configuration of the ion generating unit 2 according to the embodiment of the present invention will be further described with reference to FIGS. 1 to 6. FIG. 6 is a VI-VI cross-sectional view showing an example of the structure of the ion generating section 2.

As shown in FIG. 6, the surface 230 of the first inclined member 23 is inclined from the first surface 231 toward the second surface 232. The surface 230 is a surface that protrudes into the duct 3 in the first inclined member 23. The first surface 231 is a wall surface of the duct 3 on the upstream side with respect to the direction D of the support member 210. The wall surface of the duct 3 corresponds to a part of the back panel 110. The second surface 232 is a surface that indicates the side protruding into the pipe 3 in the support member 210.

In addition, the first inclined member 23 is formed in a flat plate shape. One end 23a of the first inclined member 23 is fixed to the wall surface of the pipe 3. Specifically, one end 23 a of the first inclined member 23 is fixed to the rear panel 110. The other end 23b of the first inclined member 23 is fixed to the support member 210. Specifically, the other end 23 b of the first inclined member 23 is fixed to the second surface 232 of the support member 210.

The surface 240 of the second inclined member 24 is inclined from the third surface 241 toward the fourth surface 242. The surface 240 is a surface indicating the side protruding into the duct 3 in the second inclined member 24. The third surface 241 is a surface that indicates the side protruding into the duct 3 in the support member 210. The fourth surface 242 is a wall surface of the duct 3 on the downstream side in the direction D with respect to the support member 210. The wall surface of the duct 3 corresponds to a part of the back panel 110.

In addition, the second inclined member 24 is formed in a flat plate shape. One end 24 a of the second inclined member 24 is fixed to the support member 210. Specifically, one end 24 a of the second inclined member 24 is fixed to the third surface 241 of the support member 210. The other end 24b of the second inclined member 24 is fixed to the wall surface of the pipe 3. Specifically, the other end 24 b of the second inclined member 24 is fixed to the rear panel 110.

The height H3 of the electrode protection member 213 is higher than the height H2 of the electrode 212 of the ion generator 21. The height H3 of the electrode protection member 213 indicates the height away from the back panel 110. That is, the height H3 indicates the height away from the back panel 110 of the electrode protection member 213.

As described above with reference to FIGS. 1 to 6, in the embodiment of the present invention, the surface 230 of the first inclined member 23 is inclined from the first surface 231 toward the second surface 232. The surface 230 is a surface that protrudes into the duct 3 in the first inclined member 23. The first surface 231 is a wall surface of the duct 3 on the upstream side with respect to the direction D of the support member 210. The second surface 232 is a surface that indicates the side protruding into the pipe 3 in the support member 210. Therefore, air flows through the duct 3 from the wall surface of the duct 3 along the surface 230 of the first inclined member 23. Therefore, it is possible to further suppress that the support member 210 obstructs the flow of air in the duct 3. As a result, the amount of ions contained in the air can be further increased.

In addition, since the first inclined member 23 is formed in a flat plate shape, the first inclined member 23 can be formed with a simple structure. In addition, one end 23 a of the first inclined member 23 is fixed to the wall surface of the duct 3, and the other end 23 b of the first inclined member 23 is fixed to the support member 210. Therefore, it is possible to further suppress that the support member 210 obstructs the flow of air in the duct 3. Therefore, the amount of ions contained in the air can be further increased.

In addition, the surface 240 of the second inclined member 24 is inclined from the third surface 241 toward the fourth surface 242. The third surface 241 is a surface showing the side protruding into the pipe 3 in the support member 210, and the fourth surface 242 is a surface showing the side protruding into the pipe 3 in the support member 210. Therefore, air flows through the duct 3 from the fourth surface 242 of the support member 210 along the surface 240 of the second inclined member 24. Therefore, it is possible to further suppress that the support member 210 obstructs the flow of air in the duct 3. As a result, the amount of ions contained in the air can be further increased.

In addition, since the second inclined member 24 is formed in a flat plate shape, the second inclined member 24 can be formed with a simple structure. In addition, since one end 24a of the second inclined member 24 is fixed to the support member 210 and the other end 24b of the second inclined member 24 is fixed to the wall surface of the duct 3, the support member 210 can be further suppressed from obstructing the air in the duct 3 flow. As a result, the amount of ions contained in the air can be further increased.

In addition, the height H3 of the electrode protection member 213 is higher than the height H2 of the electrode 212 of the ion generator 21. Therefore, both electrodes 212 can be reliably protected.
