Detailed Description

Embodiments of the present invention will be described below with reference to the drawings. In the drawings, the same or corresponding portions are denoted by the same reference numerals, and description thereof will not be repeated.

[ first embodiment ]

A discharge device 100 according to a first embodiment of the present invention will be described with reference to fig. 1 to 4. First, a discharge device 100 according to a first embodiment is described with reference to fig. 1. Fig. 1 is a diagram showing a discharge device 100. The discharge device 100 discharges to generate active species. The active species contains ions.

The discharge device 100 includes a plurality of electrodes 19, a generating section 18, and a housing section 90. The electrode 19 is discharged by applying a voltage. The plurality of electrodes 19 are two electrodes. That is, the plurality of electrodes 19 is a pair of electrodes 19. The generator 18 is supplied with electric power from a power source. The generating section 18 generates a voltage.

The housing 90 houses a part of the pair of electrodes 19 and the generating section 18. The housing portion 90 includes a base portion 1 and a cover portion 2. The base portion 1 supports the lid portion 2. The cover portion 2 covers the base portion 1.

Next, the base portion 1 will be described in detail with reference to fig. 1 and 2. Fig. 2 is a schematic view of the base portion 1. Fig. 2 shows the base portion 1 with the cover portion 2 removed for understanding the invention. The base portion 1 has a first arrangement portion 101, a second arrangement portion 102, and a connection portion 16.

A pair of electrodes 19 and a first substrate 171 are arranged in the first arrangement portion 101. The first arrangement portion 101 has a pair of through holes. The width of the first arrangement portion 101 in the first direction PD1 is a first width LA. The first direction PD1 is a direction along a direction from one electrode 19 toward the other electrode 19 of the pair of electrodes 19. The first direction PD1 crosses the second direction PD 2. The second direction PD2 is a direction along the direction from the first arrangement portion 101 toward the second arrangement portion 102. Specifically, the first direction PD1 is orthogonal to the second direction PD 2.

The pair of electrodes 19 discharges by applying a voltage. Specifically, the high voltage generated by the generator 18 is applied to the pair of electrodes 19. A pair of electrodes 19 generate ions. A part of the pair of electrodes 19 is fixed on the first substrate 171. Further, when the first substrate 171 is disposed at the first disposition portion 101, a part of the pair of electrodes 19 protrudes from the through hole of the first disposition portion 101. Specifically, as shown in fig. 1, a part of the pair of electrodes 19 is housed inside the housing portion 90, and the other part of the pair of electrodes 19 is exposed outside the housing portion 90. The pair of electrodes 19 exposed to the outside extend along the third direction PD 3. The third direction PD3 is a direction along the direction from the base portion 1 toward the cover portion 2.

The first substrate 171 electrically connects the pair of diodes 172 to the generation section 18. The first substrate 171 is a circuit substrate formed with a pattern connecting the pair of diodes 172 and the generating section 18. The first substrate 171 has an electrode arrangement portion 173, and the electrode arrangement portion 173 is provided with the electrode 19.

The pair of diodes 172 is connected to the generation section 18 and the electrode 19 via the pattern of the first substrate 171. The pair of diodes 172 is disposed between the pair of electrode disposition portions 173, for example.

The second arrangement portion 102 is arranged with the generation portion 18. The second arrangement portion 102 is connected to the first arrangement portion 101. The width of the second arrangement portion 102 in the first direction PD1 is the second width LB. The second width LB is smaller than the first width LA. In other words, the width of the receiving portion 90 in the first direction PD1 from the first arrangement portion 101 to the second arrangement portion 102 becomes smaller. That is, the first width LA of the first arrangement portion 101 is larger than the second width LB of the second arrangement portion 102.

The generating unit 18 includes a second substrate 181, a transformer 183, and a connection terminal 185 (see fig. 1). A transformer 183 is disposed on the second substrate 181. The transformer 183 boosts the voltage. In other words, the transformer 183 generates a high voltage. Power is supplied from the power supply to the connection terminal 185.

Next, the base portion 1 will be described in further detail with reference to fig. 1 and 2. The pair of electrodes 19 is arranged along the first direction PD 1. That is, the pair of electrodes 19 can be arranged in the portion of the first width LA. The first width LA of the first arrangement portion 101 is different from the second width LB of the second arrangement portion 102. Specifically, the second width LB of the second arrangement portion 102 is smaller than the first width LA of the first arrangement portion 101. Therefore, the pair of electrodes 19 can be disposed on the first substrate 171 with a predetermined gap therebetween, and the second disposition portion 102 can be made smaller than the first disposition portion 101. As a result, the housing portion 90 of the discharge device 100 can be made small while securing a predetermined distance between the electrodes 19 and 19. Further, since discharge device 100 can be downsized, discharge device 100 can be easily mounted on various electric devices 200. As a result, the degree of freedom in designing a product in which the discharge device 100 is mounted is improved.

As shown in fig. 1 and 2, the discharge device 100 has a substantially T-shape. The shape of the first arrangement portion 101 is made different from that of the second arrangement portion 102 by making the width of the first arrangement portion 101 different from that of the second arrangement portion 102. The first arrangement portion 101 is a rectangular shape having a pair of long sides along the first direction PD1 and a pair of short sides along the second direction PD 2. Further, the second arrangement portion 102 is a rectangular shape having a pair of short sides along the first direction PD1 and a pair of long sides along the second direction PD 2. Often, the short sides of smaller objects are difficult for a user to grasp. In other words, in the case where the object is small, the user easily grasps the long side of the object. Further, since the electrodes 19 are arranged, it is difficult for the user to grasp the first arrangement portion 101. Therefore, the user can be urged to hold the second arrangement portion 102. As a result, the user can be inhibited from grasping the first arrangement portion 101 on which the pair of electrodes 19 are arranged.

One electrode 19 of the pair of electrodes 19 is disposed on the one end portion side in the direction along the second direction PD2 in the first substrate 171. The other electrode 19 of the pair of electrodes 19 is disposed on the other end side in the direction along the second direction PD2 in the first substrate 171. A pair of diodes 172 is disposed between the pair of electrodes 19. The distance between one electrode 19 of the pair of electrodes 19 and the other electrode 19 of the pair of electrodes 19 in the first direction PD1 is larger than the distance of the generation section 18 in the first direction PD 1. Therefore, the pair of electrodes 19 can be disposed on the first substrate 171 at a predetermined interval at which ions can be sufficiently generated.

The pair of electrodes 19 are, for example, needle-shaped or brush-shaped electrodes. The corona is generated by a pair of electrodes 19 to which a high voltage is applied. That is, the pair of electrodes 19 are discharged to generate ions. One electrode 19 of the pair of electrodes 19 has a polarity different from that of the other electrode 19 of the pair of electrodes 19. The pair of electrodes 19 having different polarities are arranged at a predetermined interval at which ions can be sufficiently generated. Therefore, it is possible to suppress ions of different polarities from unintentionally reacting with each other.

For example, one electrode 19 of the pair of electrodes 19 discharges positive ions by electric discharge. The positive ion is in the hydrogen ion (H)⁺) Cluster ion (H + (H) formed by clustering a plurality of water molecules around (i.e., a plurality of water molecules)₂O)_m(m is any positive number not less than zero)). Further, for example, the other electrode 19 of the pair of electrodes 19 discharges negative ions by electric discharge. The negative ion is oxygen ion (O)^2-) Cluster ion (O) formed by clustering a plurality of water molecules around (A)₂-(H₂O)_n(n is an arbitrary positive number equal to or greater than zero)).

In the case of releasing positive ions and negative ions, the larger the interval between the electrode 19 for releasing positive ions and the electrode 19 for releasing negative ions, the more the amount of ions released from the respective electrodes 19 increases.

The released positive and negative ions, respectively, for example, surround mold floating in the air, causing chemical reactions on the surface of the mold. The hydroxyl radical (. OH) of the active species is generated by a chemical reaction. Further, the mold is removed by the action of hydroxyl radical (. OH).

Next, the housing portion 90 will be described in detail with reference to fig. 1 to 4. Fig. 3 is a view showing the cover 2. Fig. 4 is a side view of the housing portion 90.

The first extending direction D1 indicates a direction from the first flat plate portion 41 toward the first inclined portion 45. Further, the opening 91 is located on one side of the first flat plate portion 41 in the second extending direction D2. The second extending direction D2 represents the opposite direction of the first extending direction D1.

The sealing material may be injected, for example, from the opening 91. The encapsulating material is an insulator. The encapsulating material is, for example, urethane resin or epoxy resin. The encapsulating material is cured with the passage of time, for example. Further, for example, the sealing material is cured by temperature (heat) or light (ultraviolet rays). The sealing material is not cured when introduced into the housing portion 90. That is, the sealing material is in a liquid state. Then, the sealing material is introduced into the housing portion 90, and the sealing material is solidified with the passage of time.

The sealing material is introduced into the internal space of the housing 20 through the opening 91.

The connection portion 16 is connected to a connector (not shown). The connection portion 16 is disposed on the second extending direction D2 side of the first support portion 11. The connection portion 16 is disposed on the third extending direction D3 side of the first support portion 11 or the fourth extending direction D4 side of the first support portion 11. That is, since the connection portion 16 is disposed on either the third extending direction D3 side or the fourth extending direction D4 side, a gap is formed at the end portion of the base portion 1 on the second extending direction D2 side. Therefore, the resin can be filled into the housing portion 90 from the gap where the connecting portion 16 is not arranged. The connection portion 16 is arranged on the fifth extending direction D5 side. The fifth extending direction D5 indicates a direction from the cover portion 2 toward the base portion 1.

The third support portion 13, the second side wall 23, and the third inclined portion 33 extend along the seventh extending direction D7. The third support portion 13, the second side wall 23, and the third inclined portion 33 are inclined. Therefore, when the sealing material injected from the opening 91 pushes out the air inside the housing portion 90, the air is discharged to the outside of the housing portion 90 through the third support portion 13, the second side wall 23, and the third inclined portion 33. As a result, when the enclosure material is filled into the interior of the enclosure portion 90, air can be prevented from remaining in the interior of the enclosure portion 90.

[ second embodiment ]

Next, an electric device 200 according to a second embodiment will be described with reference to fig. 1 to 8. The electrical device 200 of the second embodiment has the discharge apparatus 100 of the first embodiment. Hereinafter, with respect to the second embodiment, description will be given of matters different from the first embodiment, and descriptions of parts overlapping with the first embodiment will be omitted. Fig. 5 is a diagram showing electric device 200 according to the second embodiment.

The electric device 200 of the second embodiment is, for example, a blower. The electrical device 200 includes a main body 201, an air blowing unit 210, a heating unit 220, an operation unit 230, and a tube 300.

The body 201 accommodates the air blowing unit 210, the heating unit 220, and the tube 300.

The air blowing unit 210 blows air. The air blowing unit 210 includes, for example, a motor and a fan. The motor rotates the fan. The fan rotates to generate wind. The air generated by the fan is sent to the first air blowing direction F1 side. The first air blowing direction F1 indicates a direction from the air blowing unit 210 toward the drum 300. The air blowing unit 210 blows air heated by the heating unit 220 to the outside of the main body 201. Specifically, the air heated by the heating unit 220 is sent out of the main body 201 through the tube 300.

The heating unit 220 is disposed in the main body 201. The heating unit 220 is disposed downstream of the air blowing unit 210 in the first air blowing direction F1. The heating unit 220 is disposed between the air blowing unit 210 and the tube 300. The heating unit 220 heats air inside the main body 201. The air heated by the heating part 220 is sent to the tube 300 by the air sending part 210. The heating part 220 includes an electric heating wire. The heating wire is, for example, nichrome or nichrome.

The operation unit 230 receives an instruction to turn on or off the air blowing unit 210 and the heating unit 220. When the operation unit 230 receives an instruction to turn on the air blowing unit 210 and the heating unit 220, the heating unit 220 heats the air inside the main body 201. Then, the air blowing unit 210 blows the air heated by the heating unit 220 in the first air blowing direction F1.

The cylinder 300 allows air to pass therethrough. Specifically, the wind generated by the air blowing unit 210 passes through the tube 300. The tube 300 corresponds to an example of an "air passage". The barrel 300 has a first opening 311 and a second opening 312. The first opening 311 is an opening closer to the heating portion 220 than the second opening 312. That is, the first opening 311 is an opening on the upstream side in the first blowing direction F1. The second opening 312 is an opening on the downstream side in the first air blowing direction F1 with respect to the first opening 311. That is, the wind is discharged from the second opening 312 to the outside of the main body 201.

Next, referring to fig. 6, electrical device 200 according to the second embodiment will be described in further detail. Fig. 6 is a diagram showing electrical device 200 and cylindrical portion 300 according to the second embodiment. In fig. 6, the structure other than the discharge device 100 and the cylindrical portion 300 is omitted for the sake of easy understanding of the present invention.

The cylindrical portion 300 includes a first arc portion 301 and an installation portion 303. The setting section 303 is provided with the electric apparatus 200. The setting portion 303 is flat. The setting portion 303 is opposed to the first supporting portion 11 of the electric apparatus 200.

The first arc portion 301 is connected to a pair of end portions of the set portion 303 in the direction of the second direction PD 2. Specifically, the first arc portion 301 is connected to an end of the installation portion 303 in the third extending direction D3 and an end of the installation portion 303 in the fourth extending direction D4.

As shown in fig. 6, the electrical device 200 further includes a plurality of first holding portions 305 and second holding portions 306.

The plurality of first holding portions 305 are two first holding portions 305. The plurality of first holding portions 305 is an example corresponding to "a pair of holding portions". The first holding portion 305 holds the discharge device 100 in the cylindrical portion 300. The first holding portion 305 has a substantially L-shape. The first holding portion 305 has a holding portion 350A and a holding portion 350B. The second disposition portion 102 of the discharge device 100 is disposed between the one holding portion 350A and the other holding portion 350B of the first holding portion 305. Therefore, discharge device 100 can be held by electrical apparatus 200 between holding portion 350A and holding portion 350B. As a result, the second arrangement portion 102 abuts on the first holding portion 305, and the discharge device 100 can be suppressed from moving in the first direction PD 1.

The second holding portion 306 restricts the movement of the discharge device 100. Specifically, the second holding portion 306 extends from the disposing portion 303 along the third direction PD 3. Therefore, the second holding portion 306 is opposed to the fifth supporting portion 15 and the fourth side wall 25. As a result, the discharge device 100 can be suppressed from moving downstream in the first blowing direction F1. That is, the first holding portion 305 and the second holding portion 306 can suppress the discharge device 100 from moving in the first blowing direction F1 and the discharge device 100 from moving in the second direction PD 2.

Next, the first holding portion 305 will be described in detail with reference to fig. 7. Fig. 7 is a view showing a section VII-VII of the electrical device 200 and the tube 300 shown in fig. 6.

As shown in fig. 6, the holding portions 350A and 350B extend in the second direction PD2, respectively. The holding portion 350A is arranged on the third extending direction D3 side. The holding portion 350B is arranged on the fourth extending direction D4 side. When the discharge device 100 is not held in the first holding portion 305, the holding portion 350A faces the holding portion 350B. When the discharge device 100 is held in the first holding portion 305, the holding portion 350A and the holding portion 350B face each other with the discharge device 100 interposed therebetween.

As shown in fig. 7, the first holding portion 305 holds the discharge device 100 so that the pair of electrodes 19 protrude toward the cylindrical portion 300. Therefore, ions can be generated inside the tube 300. As a result, the wind passing through the inside of the tube 300 can easily contain ions.

The widths of the holding portion 350A and the holding portion 350B in the first direction PD1 are the third width LC. The third width LC is less than the first width LA and greater than the second width LB. That is, holding portion 350A is disposed between fourth support portion 14A and second support portion 12A, and holding portion 350B is disposed between fourth support portion 14B and second support portion 12B. Therefore, when the discharge device 100 moves to the upstream side in the first air blowing direction F1, the first holding portion 305 abuts against the third support portion 13 and the second side wall 23. As a result, the discharge device 100 can be suppressed from moving toward the first air blowing direction F1.

Holding portion 350A faces second supporting portion 12A, first side wall 22A, and second inclined portion 32. Further, the holding portion 350B is opposed to the second support portion 12B, the first side wall 22B, and the second inclined portion 32.

The holding portion 350A has a first extended portion 351A and a second extended portion 352A. Further, the holding portion 350B has a first extended portion 351B and a second extended portion 352B. The first extended portion 351A and the first extended portion 351B extend from the installation portion 303 in the sixth extending direction D6.

First extension 351A faces second support portion 12A and first sidewall 22A. That is, when discharge device 100 moves toward third extending direction D3, first extending portion 351A abuts second supporting portion 12A and first side wall 22A. The first extended portion 351B faces the second support portion 12B and the first side wall 22B. That is, when the discharge device 100 moves toward the fourth extending direction D4, the first extending portion 351B abuts against the second support portion 12B and the first side wall 22B. As a result, the discharge device 100 can be prevented from moving toward the third extending direction D3 and the discharge device 100 can be prevented from moving toward the fourth extending direction D4.

The second extension portion 352A extends from the first extension portion 351A in a direction approaching the holding portion 350B. The second extension portion 352A has a facing portion 353A. The facing portion 353A faces the second inclined portion 32A. The facing portion 353A has an inclined surface having the same angle as the second inclined portion 32A. Further, the second extension portion 352B extends from the first extension portion 351B in a direction approaching the holding portion 350A. The second extension portion 352B has a facing portion 353B. The facing portion 353B faces the second inclined portion 32B. The facing portion 353B has an inclined surface having the same angle as the second inclined portion 32B. Therefore, when the discharge device 100 moves in the sixth extending direction D6, the facing portion 353A abuts against the second inclined portion 32A, and the facing portion 353B abuts against the second inclined portion 32B. As a result, the discharge device 100 can be prevented from moving toward the sixth extending direction D6.

Next, referring to fig. 1 and 5 to 8, electrical device 200 will be described in further detail. Fig. 8 is a view of the tube 300 from the second holding portion 306 side. As shown in fig. 8, the cylindrical portion 300 further has a second arc portion 302. The second arc portion 302 covers the discharge device 100. Specifically, the second arc portion 302 covers the discharge device 100 on the sixth extending direction D6 side. The second arc portion 302 abuts a pair of end portions of the installation portion 303 in the direction of the second direction PD 2. Specifically, the second arc portion 302 abuts against an end of the installation portion 303 in the third extending direction D3 and an end of the fourth extending direction D4.

As shown in fig. 1, the first inclined portion 45 of the receiving portion 90 of the present embodiment is inclined from one end portion along the first direction PD1 of the first flat plate portion 41 toward the first arrangement portion 101. Therefore, as shown in fig. 5, when the second opening 312 side of the tube portion 300 is inclined, the first inclined portion 45 can be arranged in accordance with the inclination. That is, the closer the angle of the first slope portion 45 is to the slope angle of the cylindrical portion 300, the closer the discharge device 100 can be arranged to the wall surface of the cylindrical portion 300. As a result, the discharge device 100 can be mounted to prevent the air passage of the cylindrical portion 300 from becoming too narrow.

For example, even when the inner diameter of the cylinder 300 decreases from the upstream side in the first air blowing direction F1 to the downstream side in the first air blowing direction F1, the discharge device 100 can be disposed in the vicinity of the wall surface on the downstream side of the cylinder 300.

As shown in fig. 1, the second inclined portion 32 of the receiving portion 90 of the present embodiment is inclined toward the second arrangement portion 102 from both end portions of the first flat plate portion 41 along the second direction PD 2. For example, when the linear discharge device 100 is attached to a curved surface, the corners of the linear discharge device 100 abut against the curved surface, and a large gap is formed between the discharge device 100 and the curved surface. This is because the portion of the discharge device 100 opposite to the curved surface does not conform to the curvature of the curved surface. On the other hand, by providing the second slope part 32 in the discharge device 100, the slope of the second slope part 32 approaches the angle of the second arc part 302. That is, the closer the angle of the second slope portion 32 is to the angle of the second arc portion 302, the closer the discharge device 100 can be made to the second arc portion 302. Therefore, even if the wall surface of the product to which the discharge device 100 is attached is a curved surface, the discharge device 100 can be installed close to the curved surface. As a result, when the discharge device 100 is mounted on a product, the discharge device 100 can be mounted on the product in a state where the discharge device 100 is closer to a curved surface.

As shown in fig. 1, the accommodating portion 90 of the present embodiment includes a plurality of inclined portions. Specifically, the receiving portion 90 includes a first inclined portion 45, a pair of second inclined portions 32, a pair of third inclined portions 33, a pair of fourth inclined portions 34, and a fifth inclined portion 35. Therefore, the more the inclined portions, the more polygonal the outer shape of the discharge device 100. That is, the more polygonal the outer shape of discharge device 100, the closer discharge device 100 can be made to the wall surface of second arc portion 302. As a result, the portion of the tube 300 through which the wind passes can be secured.

The embodiments of the present invention have been described above with reference to the drawings. However, the present invention is not limited to the above-described embodiments, and can be implemented in various forms without departing from the scope of the invention. Further, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the above embodiments. For example, some of the components may be deleted from all the components shown in the embodiments. Further, the constituent elements relating to the different embodiments may be appropriately combined. For easy understanding, the drawings mainly show the respective components, and the thickness, length, number, interval, and the like of the respective components shown in the drawings are different from those of the actual drawings in terms of convenience of manufacturing the drawings. The speed, material, shape, size, and the like of each component shown in the above-described embodiments are examples, and are not particularly limited, and various modifications can be made without substantially departing from the structure of the present invention.

(1) In the first embodiment, the filling of the sealing material into the internal space of the housing portion 90 has been described, but the present invention is not limited to this. That is, the base portion 1 may have the housing portion 90 with the lid portion 2 attached thereto, without filling the interior space of the housing portion 90 with the sealing material.

(2) In the first embodiment, the housing 90 houses the pair of electrodes 19 and the transformer 183, but is not limited thereto. For example, the transformer 183 may be disposed outside the housing unit 90 as long as the pair of electrodes 19 is disposed in the first disposition portion 101.

(3) In the second embodiment, an example of the electric device 200 is a blower, but is not limited thereto. For example, the electrical device 200 may also be a hair iron. Further, the electric appliance 200 may also be, for example, a toothbrush, a beauty device, an air conditioner, an air cleaner, a vacuum cleaner, a refrigerator, and a washing machine.

(4) In the second embodiment, the first holding portion 305 and the second holding portion 306 hold the discharge device 100, but is not limited thereto. For example, the electrical device 200 may include a third holding portion for holding the connection portion 16 side.

(5) In the first and second embodiments, the third support portion 13, the second side wall 23, and the third inclined portion 33 extend along the seventh extending direction D7, but are not limited thereto. For example, the third support portion 13, the second side wall 23, and the third inclined portion 33 inside the receiving portion 90 extend along the seventh extending direction D7. The third support portion 13, the second side wall 23, and the third inclined portion 33 outside the receiving portion 90 extend in the second direction PD 2. That is, the shape of the inside of the housing portion 90 is different from the shape of the outside of the housing portion 90. Therefore, when the sealing material injected from the opening 91 pushes out the air inside the housing portion 90, the air is discharged to the outside of the housing portion 90 along the third support portion 13, the second side wall 23, and the third inclined portion 33 inside the housing portion 90. When the discharge device 100 is mounted on the electrical apparatus 200, the third support portion 13, the second side wall 23, and the third inclined portion 33 outside the housing portion 90 abut against the pair of first holding portions 305. As a result, the air inside the housing portion 90 can be easily pushed out, and the movement of the discharge device 100 can be more effectively suppressed.
