Description

Discharge device

The present invention relates to a discharge device included in a device such as an air conditioner.

Conventionally, as a discharge device, an ion generating device for purifying, sterilizing, or deodorizing indoor air is known. The ion generating device applies a high voltage to the discharge electrode in the shape of a needle or a brush, and generates a corona discharge between the tip of the discharge electrode and the induction electrode, thereby generating ions. Such an ion generating device is usually installed in an air path that blows out air from an air conditioner.

An ion generating device, as disclosed in Patent Document 1, generally generates positive ions and negative ions. Therefore, the ion generation device includes, as the discharge electrode, a discharge electrode on the positive side that generates positive ions, and a discharge electrode on the negative side that generates negative ions.

Specifically, the ion generating device generates a positive ion by applying a positive high voltage between the discharge electrode on the positive side and the induction electrode, and generates a positive ion by applying a negative voltage between the discharge electrode on the negative side and the induction electrode. At high voltage, corona discharge generates negative ions.

In addition, the generated positive ions and negative ions are in contact with each other, the electrical properties are neutralized, and the amount of ions is reduced. Therefore, in Patent Document 2, in order to make it difficult to mix positive ions and negative ions, a partition plate is provided between the positive ion generating element having the discharge electrode on the positive side and the negative ion generating element having the discharge electrode on the negative side. The partition plate is parallel to the flow direction of the wind on the air path.

Patent Document 1: Japanese Patent Laid-Open No. 2010-044917. Patent Document 2: Japanese Patent Laid-Open No. 2009-66029.

However, the partition plate makes it difficult to mix the generated positive ions and negative ions. On the other hand, the generated positive ions and negative ions are attached to the partition plate and have the effect of reducing the amount of ions. Therefore, as disclosed in Patent Document 2, a structure in which only a partition plate is simply provided between the positive ion generating element and the negative ion generating element has the problem that there is a risk that the amount of ions may decrease.

An aspect of the present invention is to provide a discharge device capable of suppressing a reduction in discharge products due to the first discharge electrode and discharge products due to the second discharge electrode.

A discharge device includes: a case, first and second discharge electrodes protruding from an upper surface of the case, and a third electrode; and between the first and second discharge electrodes and the third electrode Discharge, thereby producing first and second discharge products; where Between the first discharge electrode and the second discharge electrode, a partition member with a height higher than the upper end portions of the first and second discharge electrodes is provided; The partition member is arranged in a direction crossing the arrangement direction of the first and second discharge electrodes, and is provided parallel to the direction along the upper surface of the casing, that is, the direction of flow of the wind, and the downstream end of the flow of the wind The part is present at the same position as or at the most downstream end of the electrode on the most downstream side of the electrode located on the most downstream side among the downstream ends of the first and second discharge electrodes and the third electrode The department is on the upstream side.

According to one aspect of the present invention, it is possible to suppress a situation in which the discharge product caused by the first discharge electrode and the discharge product caused by the second discharge electrode are mixed and reduced.

[Embodiment 1] (Configuration of ion generating device 1) (Outline of the configuration of the ion generator 1) Hereinafter, an embodiment of the present invention will be described based on the drawings. FIG. 1 is a perspective view showing the configuration of an ion generator 1 as a discharge device of this embodiment. FIG. 2(a) is a front view of the ion generating device 1, FIG. 2(b) is a plan view of the ion generating device 1, and FIG. 2(c) is the ion generating device 1 shown in FIG. 2(b). ) In the A direction side view, FIG. 2(d) is the BB cross-sectional view in FIG. 2(b) of the ion generating device 1, FIG. 2(e) is the Side view in the direction C in FIG. 2(b). FIG. 3 is an explanatory diagram showing the positional relationship of the positive-side discharge electrode 11, the partition plate 14, and the induction electrode 16 of the ion generator 1.

As shown in FIGS. 1 to 3, the ion generating device 1 has a positive side discharge electrode (first discharge electrode) 11, a negative side discharge electrode (second discharge electrode) 12, a housing portion 13, and a partition plate (partition plate Components) 14, electrode protection portion 15, induction electrode 16 (third electrode, see FIG. 3), and electrode substrate 17 (see FIG. 3).

The case portion 13 is formed of an insulating resin, and has a box shape, for example. The housing portion 13 accommodates the electrode substrate 17 and a circuit board (not shown) and the like inside. The electrode substrate 17 is provided with positive-side and negative-side discharge electrodes 11 and 12 with respect to the upper surface in the normal direction (see FIG. 3 ). In addition, sensing electrodes 16 are provided around the positive and negative discharge electrodes 11 and 12 on the upper surface of the electrode substrate 17. The upper surface of the induction electrode 16, that is, the upper surface of the electrode substrate 17 is covered by the resin layer 18. In addition, FIG. 3 shows only the positive side discharge electrode 11.

The circuit board has a discharge voltage supply circuit that generates positive and negative high-voltage electricity and the like. The voltage generated by the discharge voltage supply circuit is supplied to the positive and negative discharge electrodes 11 and 12 and the induction electrode 16. Specifically, the discharge voltage supply circuit applies a high-voltage positive pulse to the positive-side discharge electrode 11, applies a high-voltage negative pulse to the negative-side discharge electrode 12, and applies the induction electrode 16 and the positive-side discharge electrode 11 to the induction electrode 16 The voltage between the negative discharge electrode 12 and the discharge.

The positive-side and negative-side discharge electrodes 11 and 12 in this embodiment are brush-shaped electrodes at the tip. These positive-side and negative-side discharge electrodes 11 and 12 protrude from the upper surface of the housing portion 13 to a position of the same height, and are in a state of being arranged with an interval.

The induction electrode 16 is insulated from the positive and negative discharge electrodes 11 and 12 and is provided around the positive and negative discharge electrodes 11 and 12.

In addition, although the ion generating apparatus 1 has a structure in which one positive side and one negative side discharge electrodes 11 and 12 are provided one by one, it may have a plurality of electrodes. This aspect is also the same as in other generating devices shown below.

(Divider 14) The partition plate 14 is formed of resin, and is provided between the positive-side discharge electrode 11 and the negative-side discharge electrode 12 so as to distinguish the space between the positive-side discharge electrode 11 and the negative-side discharge electrode 12. The height of the partition plate 14 is higher than the height of the upper end portions of the positive and negative discharge electrodes 11 and 12.

Here, the ion generating device 1 preferably crosses the direction in which the positive side discharge electrodes 11 and the negative side discharge electrodes 12 intersect in the wind path of the air blowing the air conditioner (machine), preferably in the orthogonal direction Install by the wind. In Fig. 1 and Fig. 2 (b), arrows indicate the direction of wind flow. Therefore, the partition plate 14 is parallel to the flow direction of the wind on the air path.

In addition, in the flow direction of the wind, the downstream end of the flow of the wind in the partition plate 14 (hereinafter referred to simply as the downstream end) is not present as compared to the downstream end of the induction electrode 16 Downstream side. That is, the downstream end of the partition plate 14 exists at the same position as the downstream end of the induction electrode 16 or upstream of the downstream end of the induction electrode 16. In the examples of FIGS. 1 to 3, the downstream end of the partition plate 14 is at the same position as the downstream end of the induction electrode 16.

Moreover, due to the positional relationship between the positive and negative discharge electrodes 11 and 12 and the induction electrode 16, the downstream ends of the positive and negative discharge electrodes 11, 12 exist compared to the downstream end of the induction electrode 16 The situation on the downstream side is as follows. That is, the downstream end of the partition plate 14 exists at the same position as the downstream end of the positive and negative discharge electrodes 11, 12 or compared to the downstream side of the positive and negative discharge electrodes 11, 12 The end is on the upstream side.

The positional relationship of the partition plate 14, the induction electrode 16, and the positive and negative discharge electrodes 11 and 12 integrated above is shown below. That is, the downstream end portion of the partition plate 14 exists at the end portion (hereinafter, referred to as an electrode) that exists on the most downstream side among the downstream end portions of the positive and negative discharge electrodes 11, 12 and the induction electrode 16. The most downstream end) at the same position or upstream of the most downstream end of the electrode. The most downstream end portion of the induction electrode 16 described here includes not only a portion formed in a substantially circular shape around the positive and negative discharge electrodes 11 and 12 but also a connection portion and a branch portion.

(Electrode protection section 15) The electrode protection portion 15 is provided at a position opposite to the partition plate 14 with respect to the positive side discharge electrode 11 and at a position opposite to the partition plate 14 with respect to the negative side discharge electrode 12. The electrode protection portion 15 is the same as the partition plate 14 and has a height higher than that of the upper end portions of the positive and negative discharge electrodes 11 and 12.

The electrode protection portion 15 is the same as the partition plate 14 and is parallel to the flow direction of the wind in the air path. In addition, the electrode protection portion 15 has a rectangular frame shape, and the inside thereof becomes an opening 15a. Specifically, the electrode protection portion 15 is formed by connecting a rod-shaped horizontal member 15b and a rod-shaped vertical member 15c. The vertical member 15c includes a first vertical member 15c1 on the upstream side and a second vertical member 15c2 on the downstream side where wind flows. The horizontal member 15b connects the upper ends of the first vertical member 15c1 and the second vertical member 15c2. In addition, the frame shape of the electrode protection portion 15 is not limited to a quadrangle.

(The arrangement state of the ion generating device 1 in the air cleaner 21) The ion generating device 1 is used by being installed in an air path that blows out air from various air conditioners. Here, the air conditioner includes an air conditioner, an air purifier, a humidifier, or other various devices having an air supply function.

4 is a longitudinal cross-sectional view of an air cleaner 21 as an air conditioner in which the ion generating device 1 is installed. As shown in FIG. 4, the air cleaner (device) 21 has a blow-out air path 23 extending in the vertical direction inside the casing 22. The upper end of the blowing air passage 23 is an opening, and serves as a blowing port 23a.

A blower 24 is provided below the blow-out air path 23, and the blower 24 sucks outside air in the blow-out air path 23 through the rear panel 25, the deodorizing filter 26, and the dust collection filter 27, for example, and sucks in the air from the blow-out port 23a Blow out.

(Operation and advantages of the air cleaner 21 and the ion generator 1) In the above-described configuration, when the blower 24 rotates, the air cleaner 21 sucks the air outside the air cleaner 21 through the rear panel 25, the deodorizing filter 26, and the dust collecting filter 27 into the blower air path 23. The air that has been sucked into the air outlet 23 flows toward the air outlet 23a in the air outlet 23 and is blown out from the air outlet 23a.

In addition, when the ion generating device 1 operates, discharge occurs between the positive side discharge electrode 11 and the negative side discharge electrode 12 and the induction electrode 16. As a result, positive ions are generated at the tip of the positive-side discharge electrode 11, and negative ions are generated at the tip of the negative-side discharge electrode 12. These positive and negative ions are blown out from the outlet 23a together with the air by the wind generated by the blower 24.

Here, if the generated positive and negative ions are mixed with each other, they are recombined, neutralized and eliminated. In this case, the ion concentration in the blowing air path 23 decreases. However, the presence of the partition plate 14 between the positive-side discharge electrode 11 and the negative-side discharge electrode 12 in the ion generating device 1 makes it difficult to mix the generated positive and negative ions with each other, and can suppress the ion concentration of the positive and negative ions. reduce.

Furthermore, in the ion generating device 1, as described above, since the partition plate 14 is provided between the positive side discharge electrode 11 and the negative side discharge electrode 12, even if the interval between the positive side discharge electrode 11 and the negative side discharge electrode 12 is Narrow conditions also make it difficult to mix the positive and negative ions that have been generated. Thus, the ion generating device 1 can narrow the interval between the positive-side discharge electrode 11 and the negative-side discharge electrode 12 and reduce the size.

On the other hand, in the ion generating apparatus 1, since the partition plate 14 in the vicinity of the positive side and negative side discharge electrodes 11 and 12 exists, the generated positive and negative ions easily adhere to the partition plate 14. If the positive and negative ions are attached to the partition plate 14, the ion concentration is reduced only by this part. Therefore, the longer the partition plate 14 is on the downstream side of the flow of the wind, the greater the amount of decrease in the ion concentration due to the adhesion of positive and negative ions to the partition plate 14. However, in the ion generating device 1, the downstream end of the partition plate 14 exists at the most downstream end of the counter electrode (at the downstream end of the positive and negative discharge electrodes 11, 12 and the induction electrode 16) The most downstream end of the electrode) at the same position or more upstream than the most downstream end of the electrode. That is, in the ion generating device 1, the downstream end of the partition plate 14 is made as short as possible, and it is possible to suppress the generation of positive and negative ions attached to the partition plate 14 and the decrease in ion concentration.

In addition, since the electrode protection portion 15 is formed by connecting the rod-shaped horizontal member 15b and the rod-shaped vertical member 15c, since there is no partition wall and the surface area is reduced, it is possible to suppress the adhesion of the generated positive and negative ions to the electrode protection portion 15 Thus, the ion concentration is reduced.

In addition, the electrode protection portion 15 and the partition plate 14 protect the positive side from the upstream and downstream sides of the flow of wind with respect to the positive and negative discharge electrodes 11 and 12 and from colliding with other objects from above And negative-side discharge electrodes 11, 12. In addition, the electrode protection unit 15 protects the positive and negative discharge electrodes 11 and 12 so that the positive and negative discharge electrodes 11 and 12 do not collide with other objects from the direction crossing the flow of the wind. In this way, in addition to the function of the partition plate 14 described above, the partition plate 14 also has a protection function for the positive side and negative side discharge electrodes 11 and 12.

In addition, in this embodiment, a case where the discharge device is the ion generating device 1 that generates positive and negative ions will be described. However, the discharge device is not limited to the ion generating device 1, and the first discharge product may be generated by the discharge between the positive side discharge electrode 11 and the induction electrode 16, and between the negative side discharge electrode 12 and the induction electrode 16 Second discharge product. In this case, in addition to positive and negative ions, the first and second discharge products generated by the discharge device may be particles of positively or negatively charged water (charged fine particle water), or a composite of charged fine particle water and active species body. The configuration of such a discharge device is the same in other embodiments below.

[Embodiment 2] Based on the drawings, other embodiments of the present invention will be described below. In addition, for the convenience of explanation, components having the same functions as those described in the above embodiments are denoted by the same symbols, and the description thereof is not repeated.

(Ion generator 2) FIG. 5( a) is a front view of the ion generator 2 of this embodiment, and FIG. 5( b) is a plan view of the ion generator 2.

As shown in FIG. 5, the ion generating device 2 also has an electrode protection portion 15 between the partition plate 14 and the positive side discharge electrode 11 and between the partition plate 14 and the negative side discharge electrode 12. That is, the positive-side and negative-side discharge electrodes 11 and 12 are surrounded by the electrode protection portion 15 on both sides in a direction crossing the flow direction of the wind. Thus, the ion generator 2 has a higher protection function of the positive and negative discharge electrodes 11 and 12 of the electrode protector 15 than the ion generator 1.

The other configuration of the ion generating device 2 is the same as the ion generating device 1 described above. The operations and advantages of the air cleaner 21 and the ion generator 2 provided with the ion generator 2 are the same as those of the air cleaner 21 and the ion generator 1 provided with the ion generator 1 described above.

[Embodiment 3] Based on the drawings, further embodiments of the present invention will be described below. In addition, for the convenience of explanation, components having the same functions as those described in the above embodiments are denoted by the same symbols, and the description thereof is not repeated.

(Ion generator 3, partition plate 14) 6 is an explanatory diagram showing the positional relationship of the positive-side discharge electrode 11, the partition plate 14, and the induction electrode 16 of the ion generation device 3 of this embodiment.

FIG. 6 shows a state where a high voltage is applied to the positive-side discharge electrode 11. As shown in FIG. 6, when a high voltage is applied to the positive-side discharge electrode 11, the front end portion is opened. This is because the multiple fibers forming the brush are separated from each other due to electric repulsion.

In the ion generating device 3, the positive-side and negative-side discharge electrodes 11 and 12 have a downstream end portion located downstream of the induction electrode 16 when a high voltage is applied. Therefore, in the ion generating device 3, the downstream end of the partition plate 14 exists at the same position as the most downstream end of the electrode or upstream of the most downstream end of the electrode. When the ion generating device 3 is used instead of the ion generating device 1, the air cleaner shown in FIG. 4 is provided with the ion generating device 3 instead of the ion generating device 1.

The other configuration of the ion generating device 3 is the same as the ion generating device 1 described above. The operations and advantages of the air cleaner 21 and the ion generator 3 provided with the ion generator 3 are the same as those of the air cleaner 21 and the ion generator 1 provided with the ion generator 1 described above.

(Embodiment 4) Based on the drawings, further embodiments of the present invention will be described below. In addition, for the convenience of explanation, components having the same functions as those described in the above embodiments are denoted by the same symbols, and the description thereof is not repeated.

(Ion generator 4) 7 is an explanatory diagram showing the positional relationship of the positive-side discharge electrode 11, the partition plate 14, and the induction electrode 16 of the ion generation device 4 of this embodiment.

As shown in FIG. 7, the ion generator 4 includes a needle-shaped positive discharge electrode 11 instead of the brush-shaped positive discharge electrode 11 shown in FIG. 3. In addition, although the negative-side discharge electrode 12 is not shown in FIG. 7, the negative-side discharge electrode 12 has the same configuration as the positive-side discharge electrode 11.

The positive-side and negative-side discharge electrodes 11 and 12 can be appropriately selected to have a brush shape or a needle shape, and are not limited to a brush shape or a needle shape. This point is also the same as in the ion generator of other embodiments.

The other structure of the ion generator 4 is the same as that of the ion generator 1 mentioned above. The operations and advantages of the air cleaner 21 and the ion generator 4 provided with the ion generator 4 are the same as those of the air cleaner 21 and the ion generator 1 provided with the ion generator 1 described above.

[Embodiment 5] Based on the drawings, other embodiments of the present invention will be described below. In addition, for the convenience of explanation, components having the same functions as those described in the above embodiments are denoted by the same symbols, and the description thereof is not repeated.

(Structure and advantages of ion generating device 5 and electrode protection part 31) FIG. 8 is a perspective view showing the configuration of the ion generating device 5 according to this embodiment. As shown in FIG. 8, the ion generating device 5 has an electrode protection part 31 instead of the electrode protection part 15 shown in FIG. 1.

The electrode protection portion 31 is located at the upstream end and the downstream end of the wind flow of the partition plate 14, respectively, and is formed by connecting two pairs of rod-shaped vertical members 31 a and a pair of rod-shaped horizontal members 31 b.

Specifically, the upstream electrode protection portion 31 has a first vertical member 31a1 that is an upstream vertical member 31a at a position opposite to the partition plate 14 with respect to the positive and negative discharge electrodes 11 and 12. The horizontal member 31b of the upstream electrode protection portion 31, that is, the first horizontal member 31b1, extends from the upper end of the first vertical member 31a1 on the positive discharge electrode 11 side to the upper end of the first vertical member 31a1 on the negative discharge electrode 12 side Department.

Similarly, the downstream electrode protection portion 31 has a downstream vertical member 31a, that is, a second vertical member 31a2, at a position opposite to the partition plate 14 with respect to the positive and negative discharge electrodes 11 and 12. The horizontal member 31b of the downstream electrode protection portion 31, that is, the second horizontal member 31b2, extends from the upper end of the second vertical member 31a2 on the positive discharge electrode 11 side to the upper end of the second vertical member 31a2 on the negative discharge electrode 12 side Department. The first horizontal member 31b1 and the second horizontal member 31b2 are connected to the partition plate 14 in the middle portion.

The electrode protection portion 31 is the same as the partition plate 14 and has a height higher than that of the upper end portions of the positive and negative discharge electrodes 11 and 12. Therefore, the electrode protection portion 31 and the partition plate 14 are the same as the electrode protection portion 15 and the partition plate 14 of the ion generating device 1, and have a protection function for the positive side and negative side discharge electrodes 11 and 12. In addition, the electrode protection portion 31 has a cross member 31b, which has a collision prevention function for other objects from the upstream and downstream sides of the flow of wind, and the positive and negative discharge electrodes 11, 12 from above. The electrode protection part 15 is higher.

Moreover, the two electrode protection parts 31 and the separator 14 are connected by the horizontal member 31b of the electrode protection part 31. Therefore, the electrode protection portion 31 and the separator 14 have higher strength than the electrode protection portion 15 and the separator 14 of the ion generating device 1, so the protection function of the positive and negative discharge electrodes 11, 12 also changes high.

In addition, since the electrode protection portion 31 is formed by connecting the rod-shaped vertical member 31a and the rod-shaped horizontal member 31b, the area surrounded by the upper surface of the housing portion 13, the left and right vertical members 31a and the horizontal member 31b (by The area surrounded by the left and right first vertical members 31a1 and the first horizontal member 31b1 and the area surrounded by the left and right second vertical members 31a2 and the second horizontal member 31b2) becomes the opening portion 31c1. Accordingly, the wind flowing on the upper surface of the housing portion 13 can flow without being disturbed by the electrode protection portion 31.

In addition, between the upstream electrode protection portion 31 and the downstream electrode protection portion 31, between the upstream first vertical member 31a1 and the downstream second vertical member 31a2, and the upstream first horizontal member 31b1 An opening 31c2 is formed between the second horizontal member 31b2 on the downstream side.

As described above, since the electrode protection portion 31 does not have the partition wall, it is possible to suppress the occurrence of positive and negative ions attached to the electrode protection portion 31 and a decrease in ion concentration.

The other configuration of the ion generating device 5 is the same as the ion generating device 1 described above. The operations of the air cleaner 21 and the ion generator 5 provided with the ion generator 5 and other advantages of the ion generator 5 are the same as those of the air cleaner 21 and the ion generator 1 provided with the ion generator 1 described above.

[Embodiment 6] Based on the drawings, further embodiments of the present invention will be described below. In addition, for the convenience of explanation, components having the same functions as those described in the above embodiments are denoted by the same symbols, and the description thereof is not repeated.

(Structure and advantages of ion generating device 6 and electrode protection part 32) FIG. 9 is a perspective view showing the configuration of the ion generator 6 as the present embodiment. As shown in FIG. 9, the ion generating device 6 has an electrode protection part 32 in addition to the electrode protection part 15 shown in FIG. 1.

The electrode protection portion 32 has the same length as the partition plate 14, and extends from the upper end of the partition plate 14 toward the positive and negative discharge electrodes 11 and 12 on the upper surface of the case portion 13 (the resin layer 18 Upper surface) parts that protrude in parallel. The electrode protection portion 32 has a plurality of openings 32a.

Since the electrode protection unit 32 is provided in addition to the electrode protection unit 15, the ion generator 6 has a higher protection function for the positive and negative discharge electrodes 11 and 12 than the ion generator 1.

The other structure of the ion generator 6 is the same as that of the ion generator 1 mentioned above. The operations of the air cleaner 21 and the ion generator 6 provided with the ion generator 6 and other advantages of the ion generator 6 are the same as those of the air cleaner 21 and the ion generator 1 provided with the ion generator 1 described above.

[Embodiment 7] Based on the drawings, further embodiments of the present invention will be described below. In addition, for the convenience of explanation, components having the same functions as those described in the above embodiments are denoted by the same symbols, and the description thereof is not repeated.

(Divider 41) FIG. 10( a) is a front view of the ion generator 7 of this embodiment, and FIG. 10( b) is a plan view of the ion generator 7 shown in FIG. 10( a ).

The ion generator 7 includes a partition plate (partition plate member) 41 instead of the partition plate 14 of the ion generator 1. The partition plate 41 is a position that intersects the partition plate 41 with respect to a line connecting the center of the positive-side discharge electrode 11 and the center of the negative-side discharge electrode 12 (hereinafter, referred to as the position of the discharge electrode in the direction of wind flow), the upstream side The part becomes longer than the downstream part. In addition, the downstream portion of the partition plate 41 becomes wider than the upstream portion.

(Advantages of ion generating device 7) In the above configuration, since the partition plate 41 is the position of the discharge electrode with respect to the wind flow direction, the upstream portion is longer than the downstream portion of the flow of the wind, so that it can be blown to the positive and negative discharge electrodes The flow of the wind of 11 and 12 is stabilized. As a result, it is possible to suppress a situation in which the positive and negative ions caused by the turbulence of the wind are mixed and the ion concentration is reduced.

In addition, since the downstream portion of the partition plate 41 becomes wider than the upstream portion, the wind passing through the positive and negative discharge electrodes 11 and 12 can be prevented from converging immediately after passing through the partition plate 41. Therefore, the position where the positive and negative ions are mixed to reduce the ion concentration moves to the downstream side, and as a result, a high concentration of ions can be supplied into the room.

In addition, the configuration of the partition plate 41 of the ion generating device 7 can be applied to other ion generating devices in the same manner.

(Configuration example of induction electrode 16) Next, various structural examples of the induction electrode 16 will be described below.

(Configuration example 1) FIG. 11 is a plan view showing a first configuration example of the induction electrode 16. The sensing electrode 16 shown in FIG. 11 is used by the user in the ion generating apparatus 1 shown in FIG. 1, for example. The induction electrode 16 is formed of a conductor (for example, copper foil) on the electrode substrate 17. The conductors around the positive and negative discharge electrodes 11 and 12 are circularly removed, and become a non-electrode region 19.

The diameter of the non-electrode region 19 around the positive and negative discharge electrodes 11 and 12 is, for example, in the range of 5 to 20 mm. In addition, even if the surface conductor of the sensing electrode 16 is exposed, a resist layer may be applied. This point is the same in the configuration example of the other induction electrode 16 shown below.

(Configuration example 2) FIG. 12 is a plan view showing a second configuration example of the induction electrode 16. In the configuration example shown in FIG. 12, the non-electrode region 19 is not completely circular, and is partially cut. That is, the induction electrode 16 is partially cut off around the non-electrode region 19.

(Construction example 3) FIG. 13 is a plan view showing a third configuration example of the induction electrode 16. The induction electrode 16 shown in FIG. 13 has ring-shaped portions 16a around the positive-side and negative-side discharge electrodes 11 and 12, respectively, and these ring-shaped portions 16a are connected to each other by a connecting portion 16c. With respect to the connecting portion 16c, the diverging portion 16h diverges perpendicularly from the connecting portion 16c, for example.

(Configuration example 4) FIG. 14 is a plan view showing a fourth configuration example of the induction electrode 16. The induction electrode 16 shown in FIG. 14 has ring-shaped portions 16b around the positive and negative discharge electrodes 11 and 12, respectively, and these ring-shaped portions 16b are connected to each other by a connecting portion 16c. With respect to the connecting portion 16c, the diverging portion 16h diverges perpendicularly from the connecting portion 16c, for example.

FIG. 19 is an explanatory diagram showing a measurement state of ion concentration used for verifying the effect of the partition plate. FIG. 20( a) is a front view showing the installation state of the ion generating device 8 in the device 51 shown in FIG. 19, and FIG. 20( b) is a DD cross-sectional view in FIG. 20( a ).

(Measurement conditions of ion concentration) As shown in (a) and (b) of FIG. 20, the ion generating device 8 is in the air path 51 a of the device 51, with the arrangement direction of the positive and negative discharge electrodes 11 and 12 orthogonal to the direction of the air path 51 a Installation. As shown in FIG. 19, the measurement point P of the ion concentration is set to a point of 350 mm from the ion generator 8 to the downwind side.

As shown in (a) and (b) of FIG. 18, the ion generating device 8 has the same electrode protection portion 31 as the ion generating device 5 described above. In the partition plate of the ion generating device 8, as shown in FIG. 20(b), four types of partition plates 42a to 42d are used.

The partition plate 42a is a partition plate between the positive side discharge electrode 11 and the negative side discharge electrode 12, and between the upstream side portion and the downstream side portion of the electrode protection portion 31 (hereinafter, referred to as a horizontal partition plate) ). The length of the partition plate 42a on the upwind side and the downwind side with respect to the position of the discharge electrode in the wind flow direction is the same. In addition, the position of the discharge electrode in the wind flow direction, as described above, is a position where a line connecting the center of the positive side discharge electrode 11 and the center of the negative side discharge electrode 12 intersects the partition plate 42a. In addition, the downstream end of the partition plate 42 a is at the same position as the downstream end of the induction electrode 16 of the ion generating device 8.

22 is a longitudinal cross-sectional view showing the configuration of the air cleaner 61 as the air conditioner of this embodiment. FIG. 23 is a perspective view showing the ion generator 71 installed in the air cleaner 61 shown in FIG. 22.

(Configuration of ion generating device 71) As shown in FIG. 22, in the air cleaner (device capable of attaching a discharge device) 61, an ion generating device 71 is installed in the blowing air path 23. As shown in FIG. 23, the ion generating device 71 is configured by removing the partition plate 14 in the ion generating device 1 shown in FIG. 1. The other configuration of the ion generating device 71 is the same as that of the ion generating device 1. In addition, the ion generating device 71 is not limited to the configuration in which the partition plate 14 is removed from the ion generating device 1, but may be the configuration in which the partition plate 14 is removed from the ion generating devices 2 to 6, or the component from which the ion generating device 7 is removed. Any one of the configurations of the separator 41. This point is the same in the following other embodiments.

(Configuration of air cleaner 61) FIG. 24 is a perspective view showing a state in which the ion generating device 71 is attached to the air outlet 23 of the air cleaner 61. FIG. 25( a) is a plan view of the state of FIG. 24, and FIG. 25( b) is a plan view of the configuration of the device attachment portion 81 of the air outlet 23 shown in FIG. 25( a ).

As shown in FIG. 25( b ), the air outlet 23 of the air cleaner 61 has a device attachment portion 81. The device attachment portion 81 has a device attachment hole 82 and a partition plate 83. The device attachment hole 82 penetrates the side wall (peripheral wall) of the blowing air passage 23 and opens.

In the device attachment hole 82, as shown in FIG. 24 and FIG. 25( a ), the ion generating device 71 is attached from the back of the blowing air path 23. Specifically, in the device attachment hole 82, the electrode protection portion 15 of the ion generating device 71 and the positive and negative discharge electrodes 11 and 12 are attached. As a result, the electrode protection portion 15 and the positive and negative discharge electrodes 11 and 12 protrude in the blowing air path 23 in a state where the ion generating device 71 is attached to the blowing air path 23.

The partition plate 83 is provided at a position upstream of the device attachment hole 82. The partition plate 83 is higher than the positive-side and negative-side discharge electrodes 11 and 12, and the longitudinal direction is a plate-shaped member parallel to the flow direction of the wind blowing out the air passage 23. The center of the partition plate 83 in the width direction is located between the positive side discharge electrode 11 and the negative side discharge electrode 12 of the ion generating device 71 attached to the device attachment hole 82. The width of the downstream side portion of the partition plate 83 where the wind flows is wider than that of the upstream side portion. In addition, the downstream end of the flow of the partition plate 83 system wind extends to the vicinity of the upstream end of the device attachment hole 82. The other structure of the air cleaner 61 is the same as that of the air cleaner 21.

Thus, the air cleaner 61 can be easily operated when it is necessary to maintain and repair the ion generating device 71 attached to the device attachment portion 81.

In addition, the air cleaner 61 has a partition plate 83 in the device attachment portion 81. Thus, the ion generating device 71 does not need to have the partition plate 83, and the structure can be simplified.

In addition, since the partition plate 83 extends to the upstream side of the flow of the wind with respect to the positive and negative discharge electrodes 11 and 12 in the state where the ion generating device 71 is attached to the device attachment portion 81, it is possible to blow The flow of wind to the positive and negative discharge electrodes 11 and 12 is stabilized. As a result, it is possible to suppress a situation in which the positive and negative ions caused by the turbulence of the wind are mixed and the ion concentration is reduced.

Furthermore, since the partition plate 83 has a wider downstream portion than the upstream portion in which the wind flows, the flow of wind blown to the positive and negative discharge electrodes 11 and 12 is stabilized.

In addition, the downstream end of the partition plate 83 extends to the vicinity of the upstream end of the device attachment hole 82 and is located upstream of the positive and negative discharge electrodes 11 and 12. Thus, it is possible to suppress a situation where the ion concentration of the positive and negative ions generated from the positive-side and negative-side discharge electrodes 11 and 12 in the partition plate 83 decreases.

In addition, the air cleaner 61 of the present embodiment is configured to directly attach the ion generating device 71 to the device attachment portion 81 of the blowing air path 23. However, the air cleaner 61 may include an attachment aid, attach the ion generation device 71 to the attachment aid, and attach the attachment aid with the ion generation device 71 attached to the blowing air path 23 constitute. In this case, the attachment assisting device includes a device attaching portion 81 having a device attaching hole 82 and a partition plate 83, and an opening for attaching the attachment assisting device is provided in the blowing air path 23. This point is the same in other embodiments below.

The air cleaner 62 of this embodiment has the apparatus attachment part 84 instead of the apparatus attachment part 81 mentioned above. The device attachment portion 84 has a partition plate 85 that replaces the device attachment hole 82 and the partition plate 83.

The downstream end portion of the flow of wind of the partition plate 85 extends toward the downstream side between the positive-side discharge electrode 11 and the negative-side discharge electrode 12 in a state where the ion generating device 71 is attached to the device attachment portion 84. Specifically, the partition plate 85 is the same as the partition plate 14 and is located between the positive-side discharge electrode 11 and the negative-side discharge electrode 12, and the downstream end of the partition plate 85 exists at the most downstream end of the electrode ( At the most downstream end among the downstream ends of the positive and negative discharge electrodes 11 and 12 and the induction electrode 16), they are at the same position or upstream of the most downstream end of the electrode.

The advantages of the air cleaner 62 resulting from this are the same as the advantages of the partition plate 14 resulting from such a configuration as described below.

That is, in the air cleaner 62, the partition plate 85 exists between the positive-side discharge electrode 11 and the negative-side discharge electrode 12, which makes it difficult to mix the generated positive and negative ions with each other, thereby suppressing the decrease in the ion concentration of the positive and negative ions .

In addition, in the air cleaner 62, a partition plate 85 exists between the positive-side discharge electrode 11 and the negative-side discharge electrode 12, whereby the distance between the positive-side discharge electrode 11 and the negative-side discharge electrode 12 of the ion generating device 71 used Narrowing makes it possible to miniaturize the ion generating device 71.

Also, in the air cleaner 62, since the downstream end of the partition plate 85 exists at the same position as the most downstream end of the electrode or upstream of the most downstream end of the electrode, it is possible to suppress the positive and Negative ions are attached to the partition plate 85 and the ion concentration is reduced. The other advantages of the air cleaner 62 are the same as the aforementioned air cleaner 61.
