Description

Discharge devices and air conditioners

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

Conventionally, as a discharge device, an ion generating device that performs indoor air purification, sterilization, deodorization, etc. is known. The ion generating device applies a high voltage to a needle-shaped or brush-shaped discharge electrode to generate 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 air out of the air conditioner.

As disclosed in Patent Document 1, the ion generating device usually generates positive ions and negative ions. Therefore, the ion generating device includes, as discharge electrodes, a positive-side discharge electrode that generates positive ions, and a negative-side discharge electrode that generates negative ions.

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

In addition, when the generated positive ions and negative ions come into contact with each other, the electricity is 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 a positive ion generating element having a positive side discharge electrode and a negative ion generating element having a negative side discharge electrode. The dividing plate is parallel to the direction of wind flow in the air path.

Patent Document 1: Japanese Patent Application Publication No. 2010-044917.

Patent Document 2: Japanese Patent Application Publication No. 2009-66029.

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

An object of one aspect of the present invention is to provide a discharge device capable of suppressing reductions in discharge products resulting from a first discharge electrode and discharge products resulting from a second discharge electrode.

A discharge device, which is provided with: a casing part, first and second discharge electrodes protruding from the upper surface of the casing part, and a third electrode; and through the first and second discharge electrodes and the third electrode discharge between them, thereby generating first and second discharge products; wherein between the first discharge electrode and the second discharge electrode, there is a separation with a height higher than the upper ends of the first and second discharge electrodes. component; the partition component is disposed in a direction intersecting the arrangement direction of the first and second discharge electrodes and parallel to the direction along the upper surface of the housing portion, that is, the flow direction of the wind. The downstream end portion is present at the same position as or at the same position as the most downstream end portion of the electrode that exists most downstream among the downstream end portions of the first and second discharge electrodes and the third electrode. The downstream end is close to the upstream side.

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

(Configuration of ion generating device 1)

(Outline of the structure of the ion generating device 1)

Hereinafter, embodiments of the present invention will be described based on the drawings. FIG. 1 is a perspective view showing the structure of an ion generating device 1 as a discharge device according to this embodiment. FIG. 2(a) is a front view of the ion generating device 1, FIG. 2(b) is a top view of the ion generating device 1, and FIG. 2(c) is a view of the ion generating device 1 in FIG. 2(b). ), (d) of FIG. 2 is a cross-sectional view of the ion generating device 1 along the line B-B in (b) of FIG. 2 , and (e) of FIG. 2 is a cross-sectional view of the above-mentioned ion generator 1 A side view of the sub-generation device 1 in the direction C in FIG. 2(b) . FIG. 3 is an explanatory diagram showing the positional relationship between the positive discharge electrode 11 , the partition plate 14 and the induction electrode 16 of the ion generating device 1 .

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

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

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 discharge electrode 11 , a high-voltage negative pulse to the negative discharge electrode 12 , and a voltage generated by the induction electrode 16 and the positive discharge electrode 11 to the induction electrode 16 . and the voltage between the negative side discharge electrode 12 to generate discharge.

In this embodiment, the tip portions of the positive and negative discharge electrodes 11 and 12 are brush-shaped electrodes. These positive-side and negative-side discharge electrodes 11 and 12 protrude from the upper surface of the case portion 13 to positions at the same height, and are arranged with intervals therebetween.

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, the ion generating device 1 is configured to have one positive side discharge electrode 11 and one negative side discharge electrode 12 each, but 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 made of resin and is provided between the positive discharge electrode 11 and the negative discharge electrode 12 so as to divide the space between the positive discharge electrode 11 and the negative 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 generator 1 is preferably arranged in an orthogonal direction to the direction intersecting the arrangement direction of the positive side discharge electrode 11 and the negative side discharge electrode 12 in the air path of the air conditioner (machine). Installed in such a way that the wind flows. In Figure 1 and Figure 2 (b), the direction of the wind flow is indicated by an arrow. Therefore, the partition plate 14 is parallel to the flow direction of the wind in the air path.

Furthermore, in the wind flow direction, the downstream end of the wind flow of the partition plate 14 (hereinafter simply referred to as the downstream end) does not exist compared to the downstream end of the induction electrode 16. downstream side. That is, the downstream end of the partition plate 14 is present at the same position as or upstream of the downstream end of the induction electrode 16 . In addition, 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 sensing electrode 16 .

In addition, due to the positional relationship between the positive and negative discharge electrodes 11 and 12 and the induction electrode 16, the downstream end of the positive and negative discharge electrodes 11 and 12 exists 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 and 12 or on the downstream side of the positive and negative discharge electrodes 11 and 12 The end is on the upstream side.

The positional relationship between the partition plate 14, the induction electrode 16, and the positive and negative discharge electrodes 11 and 12 shown above is as follows. That is, the downstream end of the partition plate 14 is located between the most downstream end of the downstream ends of the positive and negative discharge electrodes 11 and 12 and the induction electrode 16 (hereinafter referred to as electrodes). The most downstream end) is at the same position or is closer to the upstream side than the most downstream end of the electrode. The electrode-most downstream end of the induction electrode 16 described here includes not only a substantially circular portion formed around the positive and negative discharge electrodes 11 and 12 but also a connecting portion and a branching portion.

(electrode protection part 15)

The electrode protection portion 15 is provided at a position opposite to the partition plate 14 of the positive discharge electrode 11 and at a position opposite to the partition plate 14 of the negative discharge electrode 12 . Like the partition plate 14 , the electrode protection portion 15 has a height higher than the heights of the upper end portions of the positive and negative discharge electrodes 11 and 12 .

Like the partition plate 14, the electrode protection part 15 is parallel to the flow direction of the wind in the air path. Moreover, the electrode protection part 15 has a quadrangular frame shape, and the inside becomes an opening part 15a. Specifically, the electrode protection part 15 is formed by connecting the rod-shaped lateral member 15b and the rod-shaped vertical member 15c. The vertical members 15c include a first vertical member 15c1 on the upstream side where the wind flows and a second vertical member 15c2 on the downstream side. The horizontal member 15b connects the upper end portions of the first vertical member 15c1 and the second vertical member 15c2 to each other. In addition, the frame shape of the electrode protection part 15 is not limited to a quadrangular shape.

(Arrangement state of ion generating device 1 in air cleaner 21)

The ion generating device 1 is installed and used in an air duct 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 with an air supply function.

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

An air blower 24 is provided at the lower part of the blowout air duct 23. The air blower 24 sucks in external air into the blowout air duct 23 through, for example, the rear panel 25, the deodorizing filter 26, and the dust collection filter 27, and removes the sucked air from the blowout outlet 23a. Blow out.

(Operations and advantages of the air purifier 21 and the ion generating device 1)

In the above-mentioned structure, when the air blower 24 rotates, the air cleaner 21 sucks the air outside the air cleaner 21 into the blowout air path 23 through the rear panel 25, the deodorizing filter 26, and the dust collection filter 27. The air sucked into the blower air duct 23 flows toward the blower outlet 23a in the blower air duct 23, and is blown out from the blower outlet 23a.

Moreover, 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 . Thereby, positive ions are generated at the tip of the positive discharge electrode 11 , and negative ions are generated at the tip of the negative discharge electrode 12 . These positive and negative ions are blown out together with the air from the blower outlet 23a by the wind generated by the blower 24.

Here, if the generated positive and negative ions are mixed with each other, they will recombine and be neutralized and destroyed. In this case, the ion concentration in the blowout air passage 23 decreases. However, by having the partition plate 14 between the positive side discharge electrode 11 and the negative side discharge electrode 12 in the ion generating device 1, it is difficult to mix the generated positive and negative ions with each other, and the ion concentration of the positive and negative ions can be suppressed. reduce.

In addition, 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, the distance between the positive side discharge electrode 11 and the negative side discharge electrode 12 is In a narrow case, it becomes difficult to mix the generated positive and negative ions with each other. thus, The ion generator 1 can be miniaturized by narrowing the distance between the positive discharge electrode 11 and the negative discharge electrode 12 .

On the other hand, in the ion generating device 1, since the partition plates 14 exist near the positive and negative discharge electrodes 11 and 12, the generated positive and negative ions easily adhere to the partition plates 14. If positive and negative ions adhere to the partition plate 14, the ion concentration decreases only by that amount. Therefore, the longer the partition plate 14 is on the downstream side of the wind flow, the greater the decrease in ion concentration caused by positive and negative ions adhering to the partition plate 14 . However, in the ion generator 1, the downstream end portion of the partition plate 14 exists between the most downstream end portions of the electrodes (the downstream end portions of the positive and negative discharge electrodes 11 and 12 and the induction electrode 16 The most downstream end of the electrode) is at the same position or is closer to the upstream side than the most downstream end of the electrode. That is, in the ion generator 1, the downstream end of the partition plate 14 is shortened as much as possible, thereby suppressing the generated positive and negative ions from adhering to the partition plate 14 and causing the ion concentration to decrease.

Furthermore, since the electrode protection part 15 is formed by connecting the rod-shaped lateral member 15b and the rod-shaped vertical member 15c, there are no partition walls and the surface area is small, so it is possible to suppress the generated positive and negative ions from adhering to the electrode protection part 15 As a result, the ion concentration decreases.

Furthermore, the electrode protection part 15 and the partition plate 14 protect the positive side from the upstream and downstream sides of the wind flow and from above with respect to the positive and negative side discharge electrodes 11 and 12 from collision with other objects. and negative side discharge electrodes 11 and 12. Furthermore, the electrode protection part 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 intersecting 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 protective function for the positive and negative discharge electrodes 11 and 12 .

In addition, in this embodiment, the 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 may be The first discharge product is generated by the discharge between the positive side discharge electrode 11 and the induction electrode 16 , and the second discharge product is generated by the discharge between the negative side discharge electrode 12 and the induction electrode 16 . In this case, the first and second discharge products generated by the discharge device may be, in addition to positive and negative ions, microparticles of positively or negatively charged water (charged microparticle water), or a complex composed of charged microparticle water and active species. body. The structure of such a discharge device is also the same in other embodiments below.

(Ion generator 2)

(a) of FIG. 5 is a front view of the ion generating device 2 of this embodiment, and (b) of FIG. 5 is a plan view of the ion generating device 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 discharge electrode 11 and between the partition plate 14 and the negative discharge electrode 12 . That is, the positive-side and negative-side discharge electrodes 11 and 12 are each surrounded by the electrode protection portion 15 on both sides in the direction intersecting the flow direction of the wind. Thereby, the ion generating device 2 has a higher protection function of the positive side and negative side discharge electrodes 11 and 12 of the electrode protection part 15 than the ion generating device 1 .

The other configurations of the ion generating device 2 are the same as the aforementioned ion generating device 1 . In addition, the operations and advantages of the air cleaner 21 and the ion generator 2 including the ion generator 2 are the same as those of the air cleaner 21 and the ion generator 1 including the ion generator 1 described above.

(Ion generating device 3, partition plate 14)

FIG. 6 is an explanatory diagram showing the positional relationship between the positive side discharge electrode 11, the partition plate 14, and the induction electrode 16 of the ion generating device 3 of this embodiment.

FIG. 6 shows a state in which 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 becomes an open shape. This is because the plurality of fibers forming the brush are separated from each other due to electrical repulsion.

In the ion generator 3 , in a state where a high voltage is applied to the positive and negative discharge electrodes 11 and 12 , the downstream end portions are located downstream of the induction electrode 16 . Therefore, in the ion generator 3, the downstream end of the partition plate 14 is located at the same position as the most downstream end of the electrode, or is located upstream of the most downstream end of the electrode. When using the ion generating device 3 instead of the ion generating device 1 , the air cleaner shown in FIG. 4 includes the ion generating device 3 instead of the ion generating device 1 .

The other configurations of the ion generating device 3 are the same as the aforementioned ion generating device 1 . In addition, the operations and advantages of the air cleaner 21 and the ion generator 3 including the ion generator 3 are the same as the operations and advantages of the air cleaner 21 and the ion generator 1 including the ion generator 1 described above.

FIG. 7 is an explanatory diagram showing the positional relationship between the positive side discharge electrode 11, the partition plate 14, and the induction electrode 16 of the ion generating device 4 of this embodiment.

As shown in FIG. 7 , the ion generating device 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 also has the same structure 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 the brush shape or the needle shape. This point is also the same as in the ion generating devices of other embodiments.

The other configurations of the ion generating device 4 are the same as the aforementioned ion generating device 1 . In addition, 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.

Other embodiments of the present invention will be described below based on the drawings. In addition, for convenience of description, components having the same functions as those described in the above embodiments are denoted by the same reference numerals, and description thereof will not be repeated.

(Configuration and advantages of ion generating device 5 and electrode protection part 31)

FIG. 8 is a perspective view showing the structure of the ion generating device 5 according to this embodiment. As shown in FIG. 8 , the ion generating device 5 has an electrode protective part 31 instead of the electrode protective part 15 shown in FIG. 1 .

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

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

Similarly, the downstream electrode protection portion 31 has a downstream vertical member 31 a , that is, a second vertical member 31 a 2 at a position opposite to the partition plate 14 with respect to the positive and negative discharge electrodes 11 and 12 . The transverse member 31b of the downstream electrode protection part 31, that is, the second transverse 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. Until the end. The first transverse member 31b1 and the second transverse member 31b2 are connected to the partition plate 14 in the middle portion.

Like the partition plate 14 , the electrode protection portion 31 has a height higher than the heights of the upper end portions of the positive and negative discharge electrodes 11 and 12 . Therefore, the electrode protection part 31 and the partition plate 14 are the same as the electrode protection part 15 and the partition plate 14 of the ion generator 1, and have the function of protecting the positive side and negative side discharge electrodes 11 and 12. In addition, since the electrode protection part 31 has the cross member 31b, it has a function of preventing collision with other objects on the upstream and downstream sides of the flow of wind, as well as on the positive and negative side discharge electrodes 11 and 12 from above. The electrode protection part 15 is higher.

Moreover, the two electrode protection parts 31 and the partition plate 14 are connected by the transverse member 31b of the electrode protection part 31. Therefore, the electrode protection part 31 and the partition plate 14 have higher strength than the electrode protection part 15 and the partition plate 14 of the ion generator 1, so the protection function of the positive side and negative side discharge electrodes 11 and 12 also changes. high.

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

Moreover, between the upstream side electrode protection part 31 and the downstream side electrode protection part 31, between the upstream side first vertical member 31a1 and the downstream side second vertical member 31a2, and the upstream side first transverse member 31b1 There is an opening 31c2 between the second transverse member 31b2 on the downstream side.

As described above, since the electrode protective portion 31 does not have a partition wall, it is possible to suppress the generated positive and negative ions from adhering to the electrode protective portion 31 and causing the ion concentration to decrease.

The other configurations of the ion generating device 5 are the same as the aforementioned ion generating device 1 . In addition, 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.

(Divider 41)

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

The ion generating device 7 includes a partition plate (partition plate member) 41 instead of the partition plate 14 of the ion generating device 1 . The partition plate 41 is a position intersecting the partition plate 41 with respect to the 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 wind flow direction discharge electrode position), the upstream side The section becomes longer than the section on the downstream side. In addition, the width of the downstream side portion of the partition plate 41 is wider than that of the upstream side portion.

(Advantages of ion generating device 7)

In the above structure, since the partition plate 41 is positioned relative to the discharge electrode in the wind flow direction, and the upstream side portion is longer than the downstream side portion of the wind flow, it is possible to blow the air to the positive and negative side discharge electrodes. The flow of wind in 11 and 12 is stabilized. This can suppress a situation where positive and negative ions are mixed due to wind turbulence and the ion concentration decreases.

Furthermore, since the downstream portion of the partition plate 41 is wider than the width of the upstream portion, the wind that has passed through the positive and negative discharge electrodes 11 and 12 can be suppressed from merging immediately after passing through the partition plate 41. Therefore, the positive and negative ions are mixed and the position where the ion concentration decreases is moved to the downstream side, and as a result, high-concentration ions can be supplied into the room.

In addition, the structure of the partition plate 41 of the ion generating device 7 is also applicable to other ion generating devices.
