Description

Ion generating device

The present invention relates to an ion generating device.

Ion generators that supply ions to indoor air are widely used. In addition, various technologies for efficiently supplying ions to indoor air in ion generating devices have been disclosed.

For example, the ion generating device described in Patent Document 1 includes a main body casing, a blower air duct, and an ion generator. The air supply air path is formed in the main body casing. The air supply air path includes a blowout outlet. The ion generator is placed in the narrowest position of the air supply air path. The ion generator generates ions. The ions are discharged from the blower port to the outside of the ion generating device.

Patent Document 1: Japanese Patent Application Publication No. 2010-287321.

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

The present invention has been made in view of the above-mentioned problems, and an object thereof is to provide an ion generating device capable of increasing the amount of ions contained in the air.

The ion generating device of the present invention includes a discharger, an air supply air duct, and a supporting member. This discharger generates a discharge factor. The discharge factor includes at least one of positive ions and negative ions. The air supply air duct sends the air containing the discharge factor to the outside of the ion generating device. The support component is fixed on the wall of the air supply air duct. The support member supports the discharger in such a manner that the discharger protrudes toward the central portion of the air supply air duct. The width of the support member in the first direction is narrower than the width of the wall surface of the air supply air duct where the support member is arranged in the first direction. The first direction is a direction that is substantially perpendicular to the air delivery direction and parallel to the wall surface of the air supply air duct.

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

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

The first air flow flows through the negative direction side of the Y-axis with respect to the ribs 22 as shown in the direction D1. 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 ribs 22 and the first wall space between pieces 25. The first air flow contains, for example, positive ions, and the second air flow contains, for example, negative ions.

As described above, as described 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 portion of the duct 3 . Therefore, by disposing the ion generator 21 in the center of the duct 3 where the wind speed is high, 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 (part of the back panel 110 ) of the duct 3 on which the support member 210 is arranged in the first direction DR1 . Therefore, the support member 210 can be suppressed from interfering with 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 to be substantially the same as the width W4 of the ion generator 21 in the first direction DR1. Therefore, the support member 210 can be further suppressed from interfering with 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 in the direction D with respect to the ion generator 21 . In addition, the ribs 22 are arranged parallel to the direction D. Therefore, collision and neutralization of positive ions and negative ions can be suppressed. 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, the rib 22 is arranged on the upstream side of the direction D with respect to the ion generator 21, but the present invention is not limited to this. For example, the rib 22 may be arranged on the downstream side in the direction D with respect to the ion generator 21 .

Next, the structure of the air purifier 100 according to the embodiment of the present invention will be further described with reference to FIGS. 1 to 4 .

As shown in FIG. 4 , the ribs 22 are integrally formed with the back panel 110 . Moreover, the rib 22 is formed in a rectangular shape. The ribs 22 extend along direction D. The height H1 of the rib 22 is greater than the height of the electrode of the ion generator 21 H2 is high. Height H1 and height H2 indicate the height in the direction away from the back panel 110 . The height H1 indicates the height in the direction away from the back panel 110 of the rib 22 . The height H2 indicates the height in the direction away from the back panel 110 of the electrode. The height H2 will be described in detail below with reference to FIG. 6 .

As described above, as described 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 the first air flow and the second air flow. Therefore, the amount of ions contained in the air discharged from the discharge port 29 can be further increased.

Moreover, the rib 22 extends along the direction D. Therefore, the rib 22 can be further suppressed from interfering with 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 such that the air on one side of the duct 3 relative to the rib 22 (the negative direction side of the Y-axis) flows toward the electrode 212a, and the air on the other side of the duct 3 relative to the rib 22 (the positive direction side of the Y-axis) flows toward the electrode 212a. The air is arranged so as 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 a user (or other components) does not come into contact with the electrode 212 when the air purifier 100 is manufactured or when the air purifier 100 is repaired.

As described above, as described 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, the amount of ions contained in the air can be further increased.

In addition, the rib 22 is such that the air on one side of the duct 3 relative to the rib 22 (the negative direction side of the Y-axis) flows toward the electrode 212a, and the air on the other side of the duct 3 relative to the rib 22 (the positive direction side of the Y-axis) flows toward the electrode 212a. ) is arranged so that the air flows toward the electrode 212b. Therefore, collision and neutralization of positive ions and negative ions can be further suppressed. 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 only needs to generate a discharge factor. The discharge factor includes at least one of positive ions and negative ions. That is, the ion generator 21 only needs to generate at least one of positive ions and negative ions.
