[0009] Embodiments of the present invention will be described below with reference to the drawings. In the drawings, the same or corresponding parts will be denoted by the same reference numerals and will not be repeated in the description.

[0010] Before describing the discharge device 1 of the present invention, we will describe the electrical equipment 5 equipped with the discharge device 1 of the present invention. Figure 1 is a perspective view showing the electrical equipment 5 equipped with the discharge device 1 according to an embodiment of the present invention.

[0011] The electrical device 5 shown in Figure 1 has a blowing function and a function to generate discharge products. In addition to the above functions, the electrical device 5 may also have a function to change the physical properties of the air. The blowing function is a function that draws the air present around the electrical device 5 into the electrical device 5 and blows the drawn-in air out to the outside of the electrical device 5. The function to generate discharge products has the function of suppressing the action of bacteria by generating ions or active species, for example. The function to change the physical properties of the air has the function of removing particles contained in the air, for example. Specifically, an electrical device 5 having a blowing function and a function to generate discharge products in the air is a discharge product generator, and includes ion generators, ozone generators, etc. Furthermore, an electrical device 5 that combines a discharge product generator with a function to remove particles contained in the air is an air purifier with a discharge product generator function. In addition to an air purifier with a discharge product generator function, the electrical device 5 may also include, for example, a humidifying air purifier with a discharge product generator function, or a dehumidifying and humidifying air purifier with a discharge product generator function.

[0012] The electrical device 5 comprises a main body 51, a holder 3, and a discharge device 1. The holder 3, to which the discharge device 1 is attached, is located inside the box-shaped main body 51.

[0013] The main unit 51 houses electrical components (not shown) for operating the electrical equipment 5. Voltage is applied to the electrical components via a power cable (not shown) provided on the outside of the main unit 51 and a power connector (not shown) provided inside the main unit 51.

[0014] An intake port 51A is provided on the side of the main body 51 to draw in air from outside the main body 51. The air drawn into the main body 51 through the intake port 51A passes through a ventilation passage (not shown) provided inside the main body 51 and is blown out to the outside of the main body 51 through an outlet port 51B provided on the top surface of the main body 51.

[0015] On the side surface of the main body 51, a holder insertion port 51C for communicating the inside and outside of the main body 51 is provided. The space inside the main body 51 that communicates with the holder insertion port 51C is in communication with the aforementioned ventilation path. Also, a power supply connector is arranged in this space.

[0016] The discharge device 1 is applied with a voltage via the aforementioned power supply connector and generates discharge products. Examples of the discharge products generated by the discharge device 1 include ions or active species. The ions include positive ions (e.g., H + (H2O) m (m is an arbitrary integer)) or negative ions (e.g., O 2- (H2O) n (n is an arbitrary integer)) or combinations thereof. Examples of the active species include hydroxyl radical (·OH), hydrogen radical (·H), oxygen radical (·O), hydroperoxyl radical (·HO2), hydrogen peroxide (H2O2), ozone (O3), etc. The discharge products, for example, have the effect of suppressing the action of bacteria and preventing the bacteria from having an adverse effect on the human body.

[0017] The discharge device 1 is housed in the holder 3 and attached to the holder 3 by being held. The discharge device 1 attached to the holder 3 is inserted into the main body 51 from the holder insertion port 51C. The discharge device 1 inserted into the main body 51 is connected to the power supply connector and arranged such that a part of the discharge device 1 is exposed on the aforementioned ventilation path. The holder 3 with the discharge device 1 arranged in this way is held by the main body 51. A voltage is applied to the discharge device 1 connected to the power supply connector. By arranging the discharge device 1 on the ventilation path, the discharge products diffuse into the air passing through the ventilation path. As a result, the discharge products are blown out to the outside of the main body 51 and suppress the action of bacteria existing outside the main body 51.

[0018] Referring to FIG. 2, the holder 3 to which the discharge device 1 of the present invention is attached will be described. FIG. 2 is a cross-sectional view of the holder 3 to which the discharge device 1 according to an embodiment of the present invention is attached.

[0019] As shown in FIG. 2, the holder 3 includes a holder base 31, a housing portion 32, a first restraint portion 33, a second restraint portion 34, and a holder holding portion 35. Hereinafter, for convenience, in the description of the holder 3, the directions shown in FIG. 2 are defined as the vertical, horizontal, left, and right directions. That is, the longitudinal direction of the holder 3 is defined as the horizontal direction. Also, the direction orthogonal to the horizontal direction is defined as the vertical direction.

[0020] The holder base 31 is a portion that sets the position of the housing portion 32 in which the discharge device 1 is housed with respect to the main body 51. The housing portion 32 has a box shape. The housing portion 32 is provided at the right end portion of the holder base 31. By appropriately setting the length of the holder base 31 in the horizontal direction, a part of the discharge device 1 housed in the housing portion 32 is arranged in the ventilation path, and the discharge device 1 is connected to the power supply connector.

[0021] At the upper part of the housing portion 32, a discharge device housing opening 32P that opens in the vertical direction is provided. The discharge device housing opening 32P communicates the inside and outside of the housing portion 32. The discharge device 1 moves in and out of the housing portion 32 through the discharge device housing opening 32P.

[0022] A bottom surface 32B is provided inside the housing portion 32. Also, the inside of the housing portion 32 has a stepped structure with steps 32A provided. The steps 32A are provided such that the lower side of the housing portion 32 where the steps 32A are provided has a smaller dimension in the horizontal direction of the space constituting the housing portion 32 than the upper side of the steps 32A. The steps 32A are used to restrain and hold the discharge device 1 housed in the housing portion 32.

[0023] Also, at the right end portion of the housing portion 32, a connector insertion opening 32E that opens in the horizontal direction is provided. The connector insertion openings 32E each communicate the inside and outside of the housing portion 32. The connector insertion openings 32E are openings for guiding the aforementioned power supply connector to the discharge device 1 housed in the housing portion 32.

[0024] The housing section 32, having the shape described above, has corners 32C and 32F on the edge that contacts the discharge device housing opening 32P and the edge of the step 32A, respectively. The corners 32C and 32F include shapes that have been chamfered, which is a common practice in machining. Furthermore, if the discharge device 1 also has similar corners (not shown), when the discharge device 1 moves in and out of the housing section 32, the corners of the discharge device 1 may get caught on the corners 32C and 32F of the housing section 32. If the corners of the discharge device 1 get caught on the corners 32C and 32F of the housing section 32, the movement of the discharge device 1 in and out of the housing section 32 may be hindered by the corners 32C and 32F.

[0025] The first restraining portion 33 protrudes to the left from the upper right end of the housing portion 32. The first restraining portion 33 catches on the discharge device 1 housed in the housing portion 32, thereby restricting the discharge device 1 from moving outward beyond the first restraining portion 33 and restraining the discharge device 1 in the housing portion 32.

[0026] The second restraining part 34 is positioned on the path along which the discharge device 1 moves in and out of the housing part 32. The second restraining part 34 is provided so as to cover a part of the discharge device housing opening 32P from the outside of the housing part 32, near the upper left end of the housing part 32. The second restraining part 34 catches on the discharge device 1 housed in the housing part 32, thereby restricting the rotational movement of the discharge device 1 around the first restraining part 33 and restraining the discharge device 1 in the housing part 32. By restraining the discharge device 1 with the second restraining part 34 and the first restraining part 33, the discharge device 1 is held in the housing part 32.

[0027] The holder holding portion 35 is connected to the left end of the holder base portion 31. The holder holding portion 35 is the part used by the user, who is the operator of the electrical equipment 5 shown in Figure 1, to hold the holder 3. By holding the holder holding portion 35, the user can insert the housing portion 32 of the holder 3 into the holder insertion opening 51C shown in Figure 1, thereby positioning the housing portion 32 inside the main body 51.

[0028] A discharge device 1 according to an embodiment of the present invention will be described with reference to Figures 2 to 4. Figure 3 is a perspective view showing a discharge device 1 according to an embodiment of the present invention. Figure 4 is a cross-sectional view of a discharge device 1 according to an embodiment of the present invention.

[0029] First, the appearance of the discharge device 1 will be described with reference to Figures 2 and 3. As shown in Figures 2 and 3, the discharge device 1 comprises a housing section 11, a discharge electrode 14, and a protective section 15.

[0030] The housing section 11 is attached to the housing section 32 by housing the discharge electrode 14 within the housing section 32 so that it is exposed to the outside of the housing section 32 and is held within the housing section 32. The housing section 11 holds the discharge electrode 14 that generates discharge products and electrical circuit components (not shown) that operate the discharge electrode 14. The housing section 11 is box-shaped, with the discharge electrode 14 provided on its exterior and housing the electrical circuit components.

[0031] The housing section 11 has a first housing section 12 and a second housing section 13. The first housing section 12 holds the discharge electrode 14. When the first housing section 12 is housed in the housing section 32, it is held by the step 32A of the housing section 32. The second housing section 13 is provided so as to overlap the first housing section 12. The longitudinal length of the first housing section 12 is greater than the length of the second housing section 13. Preferably, the longitudinal length of the second housing section 13 is less by a predetermined length than the longitudinal length of the space on the bottom surface 32B side where the step 32A of the housing section 32 is provided. In this way, when the second housing section 13 moves in and out of the housing section 32, a space is created between the second housing section 13 and the housing section 32 in the longitudinal direction of the housing section 32. As a result, the second housing section 13 moves inside and outside the housing section 32, avoiding the step 32A of the housing section 32.

[0032] Preferably, the longitudinal center of the second housing portion 13 is positioned towards one end of the first housing portion 12 relative to the longitudinal center of the first housing portion 12. Furthermore, when the housing portion 11 is housed in the housing portion 32, the second housing portion 13 is positioned away from the step 32A of the housing portion 32 in the longitudinal direction of the housing portion 11. In this way, when the housing portion 11 moves in and out of the housing portion 32, a space is created between the second housing portion 13 and the housing portion 32 in the longitudinal direction of the housing portion 32. As a result, the housing portion 11 moves in and out of the housing portion 32 while avoiding the step 32A of the housing portion 32.

[0033] Preferably, the second housing portion 13 is positioned between the longitudinal ends of the first housing portion 12 in the longitudinal direction. In this configuration, when the housing portion 11 rotates around any position on the first housing portion 12 and moves in and out of the housing portion 32, a space is created between the second housing portion 13 and the housing portion 32. As a result, the housing portion 11 moves in and out of the housing portion 32 while avoiding the step 32A of the housing portion 32 and the inner surfaces of the housing portion 32.

[0034] With the shapes of the first housing portion 12 and the second housing portion 13 described above, when the housing portion 11, which is in an oblique position relative to the housing portion 32, is rotated and moved in and out of the housing portion 32, the second housing portion 13 is accommodated while avoiding the step 32A of the housing portion 32. As a result, the housing portion 11 is accommodated without getting caught on the step 32A of the housing portion 32, that is, it is easily accommodated.

[0035] The first housing section 12 has a bottom wall 120 and two side walls 121 and 122 that face each other in the longitudinal direction of the bottom wall 120. At least one of the two side walls 121 and 122 is connected to the bottom wall 120 via curved surfaces 12A and 12B. With this shape of the first housing section 12, when the housing section 11 comes into contact with the corner 32C of the housing section 32 and the curved surfaces 12A and 12B of the first housing section 12 as the housing section 11 moves in and out of the housing section 32, the curved surfaces 12A and 12B of the first housing section 12 guide the corner 32C of the housing section 32. As a result, the first housing section 12 moves in and out of the housing section 32 without getting caught on the corner 32C of the housing section 32.

[0036] The second housing section 13, like the first housing section 12, has a bottom wall 130 and two side walls 131 and 132 that face each other in the longitudinal direction of the bottom wall 130. When the second housing section 13 is housed in the housing section 32, one of the side walls 131 faces the step 32A of the housing section 32. The bottom wall 130 and one of the side walls 131 of the second housing section 13 are connected via a curved surface 13A.

[0037] Preferably, the second housing section 13 has a bottom wall 130 and the other side wall 132 connected via a curved surface 13B.

[0038] The first housing portion 12 is provided with a recessed hook portion 12C into which the first restraint portion 33 catches. Preferably, the hook portion 12C is installed on the first housing portion 12 on the opposite side from the second housing portion 13. With such a hook portion 12C, the housing portion 11 can move in and out of the housing portion 32 while the first restraint portion 33 is hooked onto the hook portion 12C. In this case, the housing portion 11 moves in and out of the housing portion 32 by rotating toward the bottom surface 32B of the housing portion 32 around the contact points of the hook portion 12C and the first restraint portion 33. As a result, when the discharge device 1 needs to move repeatedly in and out of the housing portion 32, the housing portion 11 moves in and out of the housing portion 32 by always passing through the same path. Furthermore, after the housing portion 11 is housed in the housing portion 32, the housing portion 11 is restrained in the housing portion 32 by maintaining the state in which the first restraining portion 33 is hooked onto the hooking portion 12C, thereby restricting the movement of the discharge device 1 in the direction of the first restraining portion 33.

[0039] The discharge electrode 14 is an electrode that generates discharge products, as described above. The discharge electrode 14 is made of a conductive material such as metal, carbon fiber, conductive fiber, and conductive resin. In this embodiment, the discharge electrode 14 is brush-shaped, with multiple linear conductors bundled together. The shape of the discharge electrode 14 is not limited to a brush shape, but can be any shape such as rod-shaped, needle-shaped, linear, fibrous, or planar. In this embodiment, the discharge electrode 14 protrudes from the surface opposite to the surface where the second housing portion 13 of the first housing portion 12 overlaps.

[0040] Preferably, multiple discharge electrodes 14 are arranged along the longitudinal direction of the housing portion 11. When the discharge electrodes 14 are arranged in this manner, a discharge product in an amount corresponding to the number of discharge electrodes 14 is generated and diffused into the ventilation passage. In this embodiment, two discharge electrodes 14 are arranged in the first housing portion 12 along the longitudinal direction of the first housing portion 12.

[0041] The protective part 15 surrounds the discharge electrode 14 while maintaining space around it, thereby protecting the discharge electrode 14. The protective part 15 is provided on the surface of the first housing part 12 on which the discharge electrode 14 protrudes, at a distance from one end of the housing part 11 in the longitudinal direction. In this configuration of the protective part 15, the second restraining part 34 can be positioned to hook onto the portion of the first housing part 12 between the end of the first housing part 12 and the protective part 15. The second restraining part 34, which hooks onto the first housing part 12, restricts the rotational movement of the first housing part 12 around the contact points of the first restraining part 33 and the hooking part 12C. As a result, the first housing part 12 is restrained by the housing part 32. Hereafter, the portion of the first housing part 12 between the end of the first housing part 12 and the protective part 15 will be referred to as the restrained portion 12D.

[0042] Next, the interior of the discharge device 1 will be described with reference to Figure 4. As shown in Figure 4, the discharge device 1 includes a connection section 21, a control board 22, a step-up transformer 23, a capacitor 24, and a high-voltage board 25 inside.

[0043] The connection portion 21 connects the electrical circuit components, including the discharge electrode 14, to an external power source via a power supply connector provided inside the main body 51. The connection portion 21 connects to the electrical circuit components housed inside the housing portion 11, and a part of it is exposed to the outside of the housing portion 11. The portion of the connection portion 21 exposed to the outside of the housing portion 11 is connected to the power supply connector. The connection portion 21 is provided in a position parallel to the hook portion 12C in the housing portion 11. The connection portion 21 is provided between the curved surface 12B connecting the bottom wall 120 and the side wall 122 of the first housing portion 12 and the hook portion 12C. With this arrangement of the connecting portion 21, when the housed portion 11 rotates and moves in and out of the housing portion 32 while the hooking portion 12C is hooked onto the first restraining portion 33, the connecting portion 21 moves without getting caught on the bottom surface 32B or the corners 32C, 32F of the housing portion 32. As a result, the housed portion 11 can easily move in and out of the housing portion 32.

[0044] The control board 22 has a wide shape and is housed in the first housing section 12. The control board 22 is also connected to the connection section 21. Voltage is applied to the control board 22 from the power supply connector via the connection section 21. The control board 22 is also equipped with a step-up transformer 23, a capacitor 24, and electrical components (not shown). The control board 22 is connected to the high-voltage board 25.

[0045] The step-up transformer 23 is a component that increases voltage and is a component with large depth and height dimensions. Preferably, the second housing section 13 houses the step-up transformer 23. In this case, height is required to house it in the second housing section 13, but as mentioned above, the longitudinal length of the second housing section 13 can be made smaller than the length of the first housing section 12. As a result, as mentioned above, the housing section 11 can move in and out of the housing section 32 without getting caught on the step 32A of the housing section 32. In this embodiment, two step-up transformers 23 with different amplification factors and shapes are housed in the second housing section 13. The two step-up transformers 23 are each mounted on the control board 22. The step-up transformer 23 corresponds to an example of the "high-voltage generating component" of the present invention.

[0046] The capacitor 24 has the function of temporarily storing the voltage from the step-up transformer 23. Like the step-up transformer 23, the capacitor 24 is a component with large depth and height dimensions. Preferably, the second housing section 13 houses the capacitor 24. In this way, as described above, the longitudinal length of the second housing section 13 can be made smaller than the length of the first housing section 12. As a result, as described above, the housing section 11 can move in and out of the housing section 32 without getting caught on the step 32A of the housing section 32. The capacitor 24 corresponds to an example of the "high voltage generating component" of the present invention.

[0047] The high-voltage substrate 25 has the role of supplying the desired high voltage obtained by the step-up transformer 23, capacitor 24, and various electrical components (not shown) to the discharge electrode 14. The high-voltage substrate 25 has a wide shape and is housed in the first housing section 12.

[0048] The attachment of the discharge device 1 to the holder 3 according to an embodiment of the present invention will be described with reference to Figures 5A to 5C. Figure 5A shows the preliminary steps of attaching the discharge device 1 to the holder 3 according to an embodiment of the present invention. Figure 5B shows the middle steps of attaching the discharge device 1 to the holder 3 according to an embodiment of the present invention. Figure 5C shows the final steps of attaching the discharge device 1 to the holder 3 according to an embodiment of the present invention.

[0049] The discharge device 1 shown in Figure 5A is attached to the holder 3 by being housed in the housing section 32 of the holder 3 and then restrained by the housing section 32. To house the discharge device 1 in the housing section 32, the hooking section 12C is hooked onto the first restraining section 33, and the discharge device 1 is rotated so that the bottom wall 130 of the second housing section 13 faces the bottom surface 32B of the housing section 32.

[0050] As the discharge device 1 rotates, the curved surface 13B of the second housing portion 13 faces the bottom surface 32B of the housing portion 32. Due to its shape, the curved surface 13B avoids the bottom surface 32B of the housing portion 32. Furthermore, even if the curved surface 13B comes into contact with the bottom surface 32B of the housing portion 32, due to its shape, the curved surface 13B does not get caught on the bottom surface 32B of the housing portion 32. As a result, the housing portion 11 can easily move in and out of the housing portion 32.

[0051] Furthermore, the curved surface 13A faces the step 32A provided inside the housing section 32. Due to its shape, the curved surface 13A avoids the corner 32F of the step 32A, or the step 32A itself. As a result, the housing section 11 moves without getting caught on the step 32A of the housing section 32.

[0052] As shown in Figure 5B, as the rotation of the discharge device 1 continues, the curved surface 12A of the first housing portion 12 faces the corner 32C of the housing portion 32 that is in contact with the discharge device housing opening 32P. Due to its shape, the curved surface 12A moves without contacting the corner 32C of the housing portion 32. Furthermore, even if the curved surface 12A of the first housing portion 12 comes into contact with the corner 32C of the housing portion 32, the curved surface 12A of the first housing portion 12 guides the corner 32C of the housing portion 32, so the first housing portion 12 moves without getting caught on the corner 32C of the housing portion 32.

[0053] As the rotation of the discharge device 1 continues, the discharge device 1 is housed in the housing section 32. As described above, the discharge device 1 moves without getting caught on the corners 32C of the housing section 32 during the process of being attached to the housing section 32. In other words, the discharge device 1 is easily housed in the holder 3.

[0054] As shown in Figure 5C, the discharge device 1 housed in the housing section 32 is restricted from moving beyond the first restraining section 33 by the first restraining section 33, and is only capable of rotational movement around the first restraining section 33. The rotational movement of the discharge device 1 is restricted by the simple operation of the second restraining section 34 hooking onto the restrained section 12D of the first housing section 12. In other words, the discharge device 1 is easily restrained by the second restraining section 34.

[0055] As described above, the discharge device 1 of the embodiment of the present invention can be easily housed in the holder 3 and can be easily restrained by the holder 3. In other words, the discharge device 1 of the embodiment of the present invention can be easily attached to the holder 3.

However, the present invention is not limited to the embodiments described above, and can be implemented in various forms without departing from the spirit of the invention. The drawings schematically show each component in order to facilitate understanding, and the thickness, length, number, spacing, etc. of each component shown may differ from the actual dimensions due to the convenience of drawing creation.
