Disclosure of Invention

Technical problem to be solved by the invention

In the ion generating device described in patent document 1, since the ion generator is disposed at the narrowest position of the air supply passage, the amount of ions contained in the air can be increased. That is, at the narrowest position, the generated ions are sent out to the blow-out port in a short time because the speed of the air flow is high. Therefore, the positive ions and the negative ions are not neutralized until the ions are sent to the outlet. Therefore, the ions can be sent out of the ion generating apparatus while maintaining the high ion concentration. However, the ion generating apparatus described above has room for improvement in that the amount of ions contained in the air is increased.

In view of the above problems, it is an object of the present invention to provide an ion generating apparatus capable of increasing the amount of ions contained in air.

Means for solving the problems

The ion generating device of the invention comprises a discharger, an air supply air path and a supporting component. The discharger generates a discharge factor. The discharge factor includes at least one of positive ions and negative ions. The air supply air path sends the air containing the discharge factors to the outside of the ion generating device. The support member is fixed to a wall surface of the air supply passage. The support member supports the discharger so that the discharger protrudes toward a center portion of the air supply passage. The width of the support member in the first direction is smaller than the width of a wall surface of the air supply duct in which the support member is disposed in the first direction. The first direction is a direction substantially perpendicular to the air delivery direction and parallel to a wall surface of the air supply duct.

Effects of the invention

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

Detailed Description

Hereinafter, embodiments of the present invention will be described with reference to the drawings (fig. 1 to 6). In the drawings, the same or corresponding portions are denoted by the same reference numerals, and description thereof will not be repeated.

First, the configuration of the air cleaner 100 according to the embodiment of the present invention will be described with reference to fig. 1. Fig. 1 is a side view showing an example of the configuration of an air cleaning apparatus 100. As shown in fig. 1, the air purification apparatus 100 includes a first unit 100A, a second unit 100B and a foot 112. The air cleaning device 100 corresponds to an example of an "ion generating device".

In the embodiment of the present invention, the X axis, the Y axis, and the Z axis are perpendicular to each other in the drawing. The Z axis is parallel to the vertical direction, and the X axis and the Y axis are parallel to the horizontal direction. The negative direction of the X axis represents the front side of the air cleaning device 100.

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

First unit 100A includes back surface plate 110, motor 132, fan 130, flow path forming member 123, duct 3, ion generating unit 2, and discharge port 29.

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

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

The fan 130 generates a flow of air. Specifically, as shown in the direction D, the fan 130 sucks air in the second unit 110B, and discharges the air from the discharge port 29 to the outside of the air purification apparatus 100 through the flow passage forming member 123 and the duct 3 in this order. The direction D represents the direction of flow of air.

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

Duct 3 causes the air discharged by fan 130 to flow toward discharge port 29. That is, duct 3 sends the air discharged by fan 130 to the outside of air purification apparatus 100. Duct 3 corresponds to an example of "air supply duct". The flow passage forming member 123 and the duct 3 will be described in detail below with reference to fig. 2.

The ion generating part 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 below with reference to fig. 5 and 6.

The rib 22 is formed to stand upright on the back surface plate 110 and project into the duct 3. The rib 22 corresponds to an example of a "plate-like member". The rib 22 will be described in detail below with reference to fig. 2 and 3.

The discharge port 29 is formed in the upper portion of the air purification apparatus 100, and discharges air containing ions to the outside of the air purification apparatus 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 adsorbing filter 153, and a dust suction filter 154. Each of the deodorizing filter 152, the formaldehyde adsorbing filter 153, and the dust suction filter 154 is formed in a flat plate shape. The frame 150 secures the filter 151 within 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 adsorbing filter 153, and the dust collecting filter 154 are stacked in the X-axis direction in this order from the front surface side. The deodorizing filter 152 deodorizes the air. The formaldehyde adsorption filter 153 adsorbs formaldehyde in the air. The dust suction filter 154 sucks dust in the air.

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

Next, the flow of air will be described. The fan 130 sucks air from the outside of the air cleaning device 100 as indicated by a 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 indicated by the direction D. 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 indicated by the direction D.

Next, the structure of the air cleaner 100 according to the embodiment of the present invention will be described with reference to fig. 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 apparatus 100. Fig. 3 is an enlarged front view showing an example of the configuration of the first unit 100A.

As shown in fig. 2 and 3, the flow passage forming member 123 is formed in an arc shape. Specifically, the center of the flow path forming member 123 is eccentric in the positive direction of the Y axis and the negative direction of the Z axis with respect to the central axis of the motor 132. That is, the flow path forming member 123 is formed such that the width W of the flow path of the air discharged from the fan 130 is increased toward the downstream in the direction D. The width W represents the distance between the outer circumference 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 duct 3. The support member 210 supports the ion generator 21 in such a manner that the ion generator 21 protrudes toward the central portion of the duct 3. Specifically, the support member 210 supports the ion generator 21 so that the ion generator 21 protrudes toward the center portion of the duct 3 in the X-axis direction.

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

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

The first inclined member 23 is disposed on the wall surface (a part of the back panel 110) of the duct 3 on the upstream side in the direction D with respect to the support member 210. The second tilting member 24 is disposed on the wall surface (a part of the back panel 110) of the duct 3 on the downstream side in the direction D with respect to the support member 210. The first tilting member 23 and the second tilting member 24 will be described in detail below with reference to fig. 5 and 6.

The lower end of the first wall member 25 is connected to the upper end of the flow passage forming member 123. The lower end of the second wall member 26 is connected to the upper end of the flow passage forming member 123. The first wall member 25 and the second wall member 26 are disposed to face each other, and form a 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 direction side of the Y axis of the duct 3, and the second wall member 26 constitutes a wall on the negative direction side of the Y axis of the duct 3. As shown in fig. 1, a part of back plate 110 forms a wall on the positive X-axis side of duct 3, and a part of partition wall 120 forms a wall on the negative X-axis side of duct 3.

Further, the rib 22 is disposed upstream in the direction D with respect to the ion generator 21. The ribs 22 are arranged parallel to the X-Z plane. The air that reaches the rib 22 is divided into a direction D1 and a direction D2, and flows out from the discharge port 29. The direction D1 is a direction indicating the first air flow, and the direction D2 is a direction indicating the second air flow.

The first air flow, as shown in the direction D1, flows through 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 stream contains, for example, positive ions and the second air stream contains, for example, negative ions.

As described above with reference to fig. 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 duct 3. Therefore, since the ion generator 21 is disposed in the center of the duct 3 at a high wind speed, the amount of ions contained in the air can be increased. The width W1 of the first direction DR1 of the support member 210 is narrower than the width W2 and the width W3 of the first direction DR1 of the wall surface (a part of the back plate 110) of the duct 3 in which the support member 210 is disposed. 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 first direction DR1 of the support member 210 is formed substantially the same as the width W4 of the first direction DR1 of the ion generator 21. 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 disposed upstream in the direction D with respect to the ion generator 21. Further, the rib 22 is arranged parallel to the direction D. Therefore, the positive ions can be suppressed from colliding with the negative ions to be neutralized. Therefore, the amount of ions contained in the air discharged from the discharge port 29 can be further increased.

In the embodiment of the present invention, the rib 22 is disposed upstream in 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 disposed downstream in the direction D with respect to the ion generator 21.

Next, the structure of the air cleaner 100 according to the embodiment of the present invention will be further described with reference to fig. 1 to 4. Fig. 4 is an IV-IV cross-sectional view showing an example of the structure of the first cell 100A. The section IV-IV 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. Further, the rib 22 is formed in a rectangular shape. The ribs 22 extend 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 heights H1 and H2 are heights indicating directions of separation from the back panel 110. The height H1 is a height indicating a direction in which the rib 22 is separated from the back panel 110. The height H2 is a height indicating a direction in which the electrode is separated from the back plate 110. The height H2 will be described in detail later with reference to fig. 6.

As described above with reference to fig. 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 air flow from the fan 130 toward the ion generator 21 can be divided into the first air flow and the second air flow by the rib 22. Therefore, the amount of ions contained in the air discharged from the discharge port 29 can be further increased.

In addition, the ribs 22 extend along the direction D. Therefore, the ribs 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.

Next, the structure of the ion generating unit 2 according to the embodiment of the present invention will be described with reference to fig. 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 generating section 2 further includes a power supply circuit unit 211, two electrodes 212, and an electrode protecting member 213. The ion generator 21 corresponds to an example of a "discharger".

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

Each of the two electrodes 212 is provided upright on the power supply circuit unit 211. In addition, the two electrodes 212 are aligned in the first direction DR 1. The first direction DR1 represents the Y-axis direction. Specifically, one electrode 212a of the two electrodes 212 is provided upright at the end on the negative direction side of the Y axis in the power supply circuit unit 211. The other electrode 212b of the two electrodes 212 is provided upright at the positive direction side end 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 arranged so that air on one side (negative Y-axis direction side) flows toward the electrode 212a with respect to the ribs 22 in the duct 3, and air on the other side (positive Y-axis direction side) flows toward the electrode 212b with respect to the ribs 22 in the duct 3. The air on the one side corresponds to the "first air flow" described with reference to fig. 2 and 3. The other side air corresponds to the "second air flow" described with reference to fig. 2 and 3.

The electrode protection member 213 is disposed on the upstream side and the downstream side in the direction D with respect to the two electrodes 212. The electrode protecting member 213 protects the two electrodes 212. Specifically, the electrode protection member 213 protects the electrode 212 so that a user (or other member) does not contact the electrode 212 when the air purification apparatus 100 is manufactured or when the air purification apparatus 100 is repaired.

As described above with reference to fig. 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 DR 1. Therefore, the air containing the positive ions and the air containing the negative ions are sent out of the air purification apparatus 100. Therefore, the amount of ions contained in the air can be further increased.

The ribs 22 are arranged so that air on one side (negative Y-axis direction side) flows toward the electrode 212a with respect to the ribs 22 in the duct 3, and air on the other side (positive Y-axis direction side) flows toward the electrode 212b with respect to the ribs 22 in the duct 3. Therefore, the positive ions can be further suppressed from colliding with the negative ions to be neutralized. Therefore, the amount of ions contained in the air can be further increased.

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 structure of the ion generating unit 2 according to the embodiment of the present invention will be further described with reference to fig. 1 to 6. Fig. 6 is a sectional view from VI to VI showing an example of the structure of the ion generating section 2.

As shown in fig. 6, the surface 230 of the first tilting member 23 is tilted from the first surface 231 toward the second surface 232. The surface 230 is a surface indicating a side of the first slope member 23 protruding into the duct 3. The first surface 231 is a wall surface of the duct 3 on the upstream 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. The second surface 232 is a surface indicating a side of the support member 210 protruding into the duct 3.

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

The surface 240 of the second tilting member 24 is tilted from the third surface 241 toward the fourth surface 242. The surface 240 is a surface indicating a side of the second slope member 24 protruding into the duct 3. The third surface 241 is a surface that indicates a side of the support member 210 that protrudes into the duct 3. 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 tilting member 24 is formed in a flat plate shape. One end 24a of the second tilting member 24 is fixed to the support member 210. Specifically, one end 24a of the second tilting 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 duct 3. Specifically, the other end 24b of the second inclined member 24 is fixed to the back 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 is a height indicating a direction away from the rear plate 110. That is, the height H3 is a height indicating a direction of separating from the rear plate 110 of the electrode protection member 213.

As described above with reference to fig. 1 to 6, in the embodiment of the present invention, the surface 230 of the first tilting member 23 is tilted from the first surface 231 toward the second surface 232. The surface 230 is a surface indicating a side of the first slope member 23 protruding into the duct 3. The first surface 231 is a wall surface of the duct 3 on the upstream side in the direction D with respect to the support member 210. The second surface 232 is a surface indicating a side of the support member 210 protruding into the duct 3. 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, the support member 210 can be further suppressed from interfering with the flow of air in the duct 3. As a result, the amount of ions contained in the air can be further increased.

Further, since the first tilting member 23 is formed in a flat plate shape, the first tilting member 23 can be formed in a simple configuration. One end 23a of the first tilting member 23 is fixed to the wall surface of the duct 3, and the other end 23b of the first tilting member 23 is fixed to the support member 210. 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.

Further, the surface 240 of the second tilting member 24 is tilted from the third surface 241 toward the fourth surface 242. The third surface 241 is a surface that indicates a side of the support member 210 that protrudes into the duct 3, and the fourth surface 242 is a surface that indicates a side of the support member 210 that protrudes into the duct 3. Therefore, the 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, the support member 210 can be further suppressed from interfering with the flow of air in the duct 3. As a result, the amount of ions contained in the air can be further increased.

Further, since the second tilting member 24 is formed in a flat plate shape, the second tilting member 24 can be formed in a simple configuration. Further, since one end 24a of the second tilting member 24 is fixed to the support member 210 and the other end 24b of the second tilting member 24 is fixed to the wall surface of the duct 3, the support member 210 can be further prevented from interfering with the flow of air in the duct 3. As a result, the amount of ions contained in the air can be further increased.

Further, 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.
