[Figure 3] This is a cross-sectional view of a holder to which a discharge device according to an embodiment of the present invention is attached. [Figure 4] This is a perspective view of a discharge device according to an embodiment of the present invention. [Figure 5] This is a cross-sectional view showing a discharge device according to an embodiment of the present invention. [Modes for carrying out the invention]
[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, an electrical device 5 equipped with the discharge device 1 of the present invention will be described with reference to Figures 1 and 2. Figure 1 is a perspective view showing an electrical device 5 equipped with a discharge device 1 according to an embodiment of the present invention. Figure 2 is a cross-sectional view of the electrical device 5 equipped with a discharge device 1 according to an embodiment of the present invention.
[0011] The electrical device 5 shown in Figures 1 and 2 has a blowing function and a function to release 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.
[0012] The air-blowing function draws air from the surroundings of 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 discharge product release function has the function of suppressing the activity of bacteria by generating ions or active species, for example. Functions that change the physical properties of the air include, for example, a function that removes particles contained in the air. Specifically, an electrical device 5 that has both an air-blowing function and a function that releases discharge products into 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 that removes particles contained in the air is an air purifier with a discharge product generation function. In addition to an air purifier with a discharge product generation function, the electrical device 5 may also include, for example, a humidifying air purifier with a discharge product generation function, or a dehumidifying and humidifying air purifier with a discharge product generation function.
[0013] 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.
[0014] The main unit 51 is equipped with components (not shown) for operating the electrical equipment 5. These components include a power cable (not shown) located outside the main unit 51 and a power supply connector (not shown) located inside the main unit 51. Voltage is applied through the power supply connector.
[0015] As shown in FIG. 2, a suction port 51A that communicates the exterior and interior of the main body 51 is provided on the back surface 511 of the main body. The suction port 51A communicates with a ventilation path 51B provided inside the main body 51. The ventilation path 51B is connected to air outlets 51C provided on the top surface 512 and the front surface 513 of the main body, respectively. The air outlet 51C communicates the ventilation path 51B with the exterior of the main body 51.
[0016] A fan 52 is installed inside the ventilation path 51B. The fan 52 is, for example, a sirocco fan. By rotating, the fan 52 generates an air current F1 that sucks air existing outside the main body 51 from the suction port 51A into the ventilation path 51B, an air current F2 in which the sucked air passes through the ventilation path 51B toward the air outlet 51C, and an air current F3 that blows out from the air outlet 51C to the exterior of the main body 51.
[0017] As shown in FIG. 1, a holder insertion port 51D that communicates the interior and exterior of the main body 51 is provided on the side surface 514 of the main body. The space inside the main body 51 that communicates with the holder insertion port 51D is connected to the ventilation path 51B shown in FIG. 2. Also, a power supply connector is arranged in this space.
[0018] A discharge device 1 is applied with a voltage via a power supply connector and discharges discharge products. Examples of the discharge products discharged 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., O2 - (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 bacteria from having an adverse effect on the human body.
[0019] The discharge device 1 is attached to the holder 3. The discharge device 1 attached to the holder 3 is inserted into the main body 51 through the holder insertion port 51D. As shown in FIG. 2, the discharge device 1 inserted into the main body 51 is connected to the power supply connector and is arranged such that a part of the discharge device 1 is exposed in the ventilation path 51B. 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. The discharge device 1 discharges discharge products into the air flow F2 passing through the ventilation path 51B. As a result, the discharge products carried by the air flow F2 passing through the ventilation path 51B are blown out of the main body 51 from the blowout port 51C, suppressing the action of bacteria existing outside the main body 51.
[0020] Referring to FIGS. 1 to 3, the holder 3 to which the discharge device 1 of the present invention is attached will be described. FIG. 3 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.
[0021] As shown in FIG. 3, the holder 3 includes a holder base 31, a housing portion 32, and a holder holding portion 33. Hereinafter, for convenience, in the description of the holder 3, the directions shown in FIG. 3 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.
[0022] The holder base 31 is a portion that sets the position of the housing portion 32 in which the discharge device 1 is housed and attached with respect to the main body 51 shown in FIG. 2. 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, the discharge device 1 housed and attached in the housing portion 32 has a part thereof arranged in the ventilation path 51B shown in FIG. 2, and the discharge device 1 is connected to the power supply connector.
[0023] As described above, the discharge device 1 is mounted in the housing section 32. The housing section 32 is box-shaped. A discharge device housing opening 32A, which opens in the vertical direction, is provided at the top of the housing section 32. The discharge device housing opening 32A connects the inside and outside of the housing section 32. The discharge device 1 moves inside and outside the housing section 32 by passing through the discharge device housing opening 32A. In addition, a connector insertion opening 32B, which opens in the horizontal direction, is provided at the right end of the housing section 32. The connector insertion opening 32B connects the inside and outside of the housing section 32. The discharge device 1 housed in the housing section 32 is connected to a power supply connector via the connector insertion opening 32B.
[0024] The holder holding portion 33 is connected to the left end of the holder base portion 31. The holder holding portion 33 is the part used by the user, who is the operator of the electrical equipment 5 shown in Figures 1 and 2, to hold the holder 3. By holding the holder holding portion 33, the user can insert the housing portion 32 and the holder base portion 31 of the holder 3 into the holder insertion opening 51D shown in Figure 1, thereby positioning the housing portion 32 inside the main body 51.
[0025] A discharge device 1 according to an embodiment of the present invention will be described with reference to Figures 1 to 5. Figure 4 is a perspective view showing a discharge device 1 according to an embodiment of the present invention. Figure 5 is a cross-sectional view of a discharge device 1 according to an embodiment of the present invention.
[0026] As shown in Figures 4 and 5, the discharge device 1 comprises a housing 11, electrical components 12, two discharge electrodes 131, 131, protective parts 141 provided on each discharge electrode 131, a connecting part 17, a partition wall 18, and a filling resin 19.
[0027] As shown in Figure 4, the housing 11 has a bottom surface 111, a front surface 112 connected to the bottom surface 111, a rear surface 113 connected to the bottom surface 111 and facing the front surface 112, two side surfaces 114, and a top surface 115 facing the bottom surface 111. The portion of the housing 11 enclosed by the bottom surface 111, a part of the front surface 112, a part of the rear surface 113, and a part of the two side surfaces 114 is housed in the housing section 32 of the holder 3. When the holder 3 housing the housing 11 is attached to the main body 51, the front surface 112 of the housing 11 faces the upstream side of the airflow F2 passing through the ventilation passage 51B shown in Figure 2. When the holder 3 housing the housing 11 is attached to the main body 51, the portion from the top surface 115 to slightly towards the bottom surface 111, including the protective section 141, is exposed to the ventilation passage 51B.
[0028] As shown in Figure 5, the top surface 115 of the housing 11 has an opening 116 that connects the inside and outside of the housing 11. Inside the housing 11, electrical components 12 for operating the discharge electrodes 131 are provided. The discharge device 1 of this embodiment has a power receiving connector 121, a control board 122, and a high-voltage board 123 as electrical components 12.
[0029] The power receiving connector 121 is a pin that is positioned approximately perpendicular to the side surface 114 of the housing 11. By connecting the power receiving connector 121 to the power supply connector, the voltage formed within the main body 51 shown in Figures 1 and 2 can be supplied to the control board 122 connected to the power receiving connector 121.
[0030] The control board 122 is located inside the housing 11. The control board 122 is a wide, plate-shaped unit. The control board 122 supplies high voltage to the high-voltage board 123, which is connected via wiring 125.
[0031] The high-voltage substrate 123 is positioned closer to the top surface 115 than the control board 122 inside the housing 11. The high-voltage substrate 123 is a wide plate shape and has multiple electrical elements 124 on the surface facing the top surface 115. The high-voltage substrate 123 generates a high voltage using components (not shown) mounted on the control board 122 and supplies that high voltage to each of the two discharge electrodes 131, 131 connected to the high-voltage substrate 123.
[0032] The discharge electrode 131 has a tip portion 13A that protrudes to the outside of the housing 11. Therefore, as shown in Figure 2, when the holder 3 housing the discharge device 1 is attached to the main body 51, the tip portion 13A of the discharge electrode 131 is positioned in the air passage 51B. The discharge electrode 131 discharges at the tip portion 13A positioned in the air passage 51B, releasing the discharge product into the air present in the air passage 51B. When an airflow F2 passes through the air passage 51B, the discharge electrode 131 releases the discharge product into the airflow F2. The discharge electrode 131 is made of a conductive material such as metal, carbon fiber, conductive fiber, and conductive resin. In this embodiment, the discharge electrode 131 is brush-shaped, with multiple linear conductors bundled together. However, the shape of the discharge electrode 131 is not limited to a brush shape, and can be any shape such as rod-shaped, needle-shaped, linear, fibrous, or planar.
[0033] As shown in Figure 5, the discharge device 1 is equipped with two discharge electrodes 131, 131. When the discharge products released from the discharge electrodes 131, 131 are positive or negative ions, the discharge product released from one discharge electrode 131 (e.g., positive ions) has the opposite polarity to the discharge product released from the other discharge electrode 131 (e.g., negative ions). When discharge products of opposing polarities come into contact, they are neutralized. Therefore, by reducing the amount of discharge products that are neutralized, the discharge device 1 can release a high concentration of discharge products. The discharge products are neutralized in the air by the attraction between the discharge products (positive and negative ions) of opposing polarities released into the air. In addition, discharge products released into the air may be absorbed by a substance with low insulating properties and then disappear within that substance.
[0034] As shown in Figure 4, the protective section 141 is separate from the housing 11. This type of protective section 141 has a simpler structure compared to the case where the protective section 141 and the housing 11 are an integrated structure. As a result, the protective section 141 can be manufactured more easily compared to the case where the protective section 141 and the housing 11 are an integrated structure. Two protective sections 141 are provided so as to sandwich one discharge electrode 131. The two protective sections 141, 141 are provided on the side of the housing 11 that is in front 112 of the discharge electrode 131 and on the side that is in rear 113 of the discharge electrode 131. That is, the two protective sections 141, 141 are provided along the ventilation passage 51B, on the upstream and downstream sides of the discharge electrode 131, respectively. The protective sections 141, 141 are positioned so as not to obstruct the airflow F2 directed toward the discharge electrode 131. Although it has been explained that the protective parts 141, 141 are provided on the front 112 side and the rear 113 side of the discharge electrode 131, they may be provided at any position on the housing 11 as long as they sandwich the discharge electrode 131 and do not obstruct the airflow F2 directed toward the discharge electrode 131. For example, the protective parts 141, 141 may be provided on the housing 11 so as to sandwich the discharge electrode 131 from the side 114 side.
[0035] With these protective parts 141, 141, the airflow F2 passing through the ventilation passage 51B proceeds directly to the discharge electrode 131 without being obstructed by the protective parts 141, 141. As a result, the discharge electrode 131 can release discharge products into the airflow F2 passing through the ventilation passage 51B. The discharge products carried by the airflow F2 from the discharge electrode 131 through the ventilation passage 51B are diffused from the discharge device 1 before they come into contact with discharge products of a different polarity from the other discharge electrode 131.
[0036] The protective section 141 is formed in a gate shape and has a rod-shaped electrode protective section 151 and a pair of rod-shaped support sections 161, 161. The pair of support sections 161, 161 protrude from the inside to the outside of the housing 11 through the opening 116. The pair of support sections 161, 161 start with the portion attached to the inside of the housing 11 and extend in a direction away from the housing 11. The ends of the pair of support sections 161, 161 are positioned further away from the housing 11 than the tip 13A of the discharge electrode 131. The electrode protective section 151 connects the end of one support section 161 to the end of the other support section 161. As a result, it is provided at a distance from the housing 11 and in a direction parallel to the top surface 115, protecting the tip 13A of the discharge electrode 131. Since the two protective parts 141, 141 with the structure described above are attached to the housing 11, the tip 13A of the discharge electrode 131 is visible from the front and side of the housing 11. With such protective parts 141, the electrode protection part 151 prevents contact with the discharge electrode 131 due to accidental work when attaching the discharge device 1 to the holder 3. It has been explained that the protective part 141 is formed in a gate shape by connecting a pair of support parts 161, 161 with the electrode protection part 151, but the pair of support parts 161, 161 and the electrode protection part 151 may be an integrated structure or a structure in which individual parts are connected. Also, it has been explained that the protective part 141 is formed in a gate shape by connecting a rod-shaped electrode protection part 151 and a pair of rod-shaped support parts 161, 161, but as long as the tip 13A of the discharge electrode 131 is visible from the front and side of the housing 11, it may be an arch shape instead of a combination of rod-shaped parts.
[0037] The electrode protection portion 151 has a curved portion 15A and a protruding portion 15B.
[0038] The curved portion 15A is formed on the part of the electrode protection portion 151 that faces the discharge electrode 131 when the electrode protection portion 151 is viewed in the direction of the top surface 117 of the housing 11. The curved portion 15A has a curved shape in which the central part along the length of the electrode protection portion 151 is further away from the electrode protection portion 151 in the direction of the airflow F2 in the ventilation passage 51B than the ends along the length of the electrode protection portion 151. In other words, the curved portion 15A surrounds the discharge electrode 131 in a curved shape while maintaining a space that is at an equivalent distance from the discharge electrode 131 along the circumferential direction of the discharge electrode 131. With such a curved portion 15A, compared to an electrode protection portion that is formed in a straight shape, for example, without a curved portion 15A, the distance from the tip 13A of the discharge electrode 131 to the electrode protection portion 151 is larger, especially in the central part along the length of the electrode protection portion 151. As a result, compared to an electrode protection section formed in a straight line, for example, without a curved section 15A, the amount of discharge product that reaches the electrode protection section 151 and is absorbed by the electrode protection section 151 is reduced, and the amount of discharge product carried by the airflow F2 passing through the ventilation passage 51B is increased. In other words, the discharge device 1 can release a high concentration of discharge product.
[0039] The protruding portion 15B extends from the end of the curved portion 15A in the direction of the airflow F2 passing through the ventilation passage 51B. In other words, the protruding portion 15B extends toward the discharge electrode 131. With such an electrode protection portion 151, the electrode protection portion 151 maintains a constant distance from the discharge electrode 131 due to the curved portion 15A. Furthermore, the distance between the protruding portion 15B and the discharge electrode 131 is smaller compared to when the electrode protection portion 151 does not have the protruding portion 15B. As a result, the protruding portion 15B prevents the user's fingers from exceeding the protection portion 141 and coming into contact with the discharge electrode 131 when the discharge device 1 is attached to the holder 3.
[0040] The electrode protection portion 151 of the protection portion 141 is supported by two support portions 161, 161. With this configuration, the protection portion 141 does not obstruct the airflow F2 directed toward the discharge electrode 131. In other words, the protection portion 141 surrounds the discharge electrode 131 while having space for the airflow F2 passing through the ventilation passage 51B to pass through. As a result, as described above, the discharge electrode 131 can reliably release the discharge product into the airflow F2 passing through the ventilation passage 51B.
[0041] The connecting portion 17 connects one support portion 161 of each of the two protective portions 141 that protect one discharge electrode 131 to one support portion 161 of each of the two protective portions 141 that protect the other discharge electrode 131. With such a connecting portion 17, the four protective portions 141, 141, 141, 141 are attached to the housing 11 together. As a result, the amount of work required to attach the four protective portions 141, 141, 141, 141 to the housing 11 is reduced compared to when the connecting portion 17 is not present.
[0042] The connecting portion 17 is plate-shaped and has a top surface 117 and a pair of end surfaces 172, 172 connected to the top surface 117. Of the pair of end surfaces 172, 172, one is located on the upstream side of the airflow F2 passing through the ventilation passage 51B, and the other is located on the downstream side of the airflow F2 passing through the ventilation passage 51B. The connecting portion 17 is positioned so that its top surface 117 is aligned with the airflow F2 passing through the ventilation passage 51B as shown in Figure 2. The connecting portion 17 is attached to the housing 11 such that a portion of the connecting portion 17, including the top surface 117, in the thickness direction protrudes outside the housing 11. That is, the connecting portion 17 is attached to the housing 11 so that the airflow F2 passing through the ventilation passage 51B is in contact with the connecting portion 17.
[0043] The connecting section 17 has a first curved surface 171. The first curved surface 171 connects the end surface 172 and the top surface 117. The airflow F2 passing through the ventilation passage 51B comes into contact with the first curved surface 171, which is located upstream of the airflow F2. The airflow F2 that comes into contact with the first curved surface 171 is guided by the first curved surface 171.
[0044] The first curved surface 171 guides the first airflow F21, which is guided by the first curved surface 171, so that it moves away from the top surface 117 of the connecting portion 17 in the thickness direction of the connecting portion 17. As a result, the discharge product moving from one discharge electrode 131, 131 to the other is carried away by the first airflow F21 guided by the first curved surface 171 and diffuses away from the connecting portion 17. Consequently, compared to the case where the connecting portion 17 does not have the first curved surface 171, the amount of discharge product moving from one discharge electrode 131, 131 to the other is reduced, and the amount of discharge product that is neutralized is reduced.
[0045] Furthermore, the connecting portion 17 also has a first curved surface 171 on the downstream end face 172 of the airflow F2. Therefore, it can be attached to the housing 11 even if the mounting positions of the upstream and downstream end faces 172 to the housing 11 are reversed. For this reason, it is not necessary to identify the mounting direction of the connecting portion 17 to the housing 11.
[0046] The connecting portion 17 closes the opening 116 of the housing 11 so as to cover the electrical components 12 located inside the housing 11. The connecting portion 17 acts as a wall that physically and visually separates the inside and outside of the housing 11. As a result, the connecting portion 17 prevents foreign objects from entering the inside of the housing 11. Furthermore, in a discharge device 1 having a connecting portion 17, the electrical components 12 are not visible from the outside of the housing 11, resulting in a more aesthetically pleasing design compared to cases where the electrical components 12 are visible from the outside.
[0047] The connecting portion 17 connects to the base ends of each support portion 161. With such a connecting portion 17, the length from the connecting portion 17 to the electrode protection portion 151 is greater compared to the case where the connecting portion 17 is not connected to the support portion 161 at its base end. As a result, the protection portion 141, which has a structure that avoids the path through which the airflow F2 passing through the ventilation passage 51B comes into contact with the discharge electrode 131, can be manufactured with smaller dimensions compared to the case where the connecting portion 17 is not connected to the base ends of the support portion 161.
[0048] The partition wall 18 protrudes from the connecting portion 17 toward the ventilation passage 51B and is formed to align with the direction of the airflow F2 passing through the ventilation passage 51B. The partition wall 18 separates the two discharge electrodes 131, 131. Such a partition wall 18 can prevent the movement of discharge products with opposing polarities that attract each other, as described above. As a result, the amount of discharge products neutralized in the air is reduced compared to when there is no partition wall 18.
[0049] As shown in Figure 5, the length L1 from the top surface 115 of the housing 11 to the top of the partition wall 18 in the direction in which the partition wall 18 protrudes from the housing 11 is greater than or equal to the length L2 from the housing 11 to the tip of the end portion 13A of the discharge electrode 131 in the direction in which the partition wall 18 protrudes from the housing 11. Furthermore, the length L1 from the top surface 115 of the housing 11 to the top of the partition wall 18 is less than or equal to the length L3 from the top surface 115 of the housing 11 to the tip surface of the electrode protection portion 151 of the protection portion 141 in the direction in which the partition wall 18 protrudes from the housing 11.
[0050] With such a partition wall 18, the shortest path from one of the two discharge electrodes 131 to the other bypasses the partition wall 18. Furthermore, based on the relationship between lengths L1, L2, and L3 described above, if the electrical equipment 5 has a size that allows the protective part 141 to be placed in the ventilation passage 51B, the discharge device 1 can be installed without hindrance, even though the partition wall 18 and the discharge electrodes 131 are provided in a protruding state. As a result of the shortest path being a bypass shape as described above, the amount of discharge product neutralized is reduced compared to the case where the shortest path from one of the two discharge electrodes 131 to the other is a straight line. Furthermore, whether or not the discharge device 1 can be installed in the electrical equipment 5 depends on the size of the protective part 141. This makes it possible to install the discharge device 1 in electrical equipment 5 that has a ventilation passage 51B of the minimum size necessary to protect the discharge electrodes 131.
[0051] As shown in Figure 4, the side surface 182 of the partition wall 18 and the top surface 117 of the connecting portion 17 are connected via a second curved surface 181. With such a partition wall 18, a portion of the airflow F2 along the partition wall 18 is guided to the second curved surface 181 at the boundary between the partition wall 18 and the top surface 115. As a result, compared to the case where there is no second curved surface 181 and the side surface 182 of the partition wall 18 and the top surface 117 of the connecting portion 17 are connected by a corner, the second airflow F22 guided to the second curved surface 181 is less turbulent, and therefore the discharge products are less likely to stagnate near the partition wall 18. This prevents contact between discharge products of different polarities that would result from such stagnation.
[0052] As shown in Figure 5, the filling resin 19 fills the inside of the housing 11 and hardens, thereby joining the electrical components 12, the discharge electrode 131, the protective part 141, the connecting part 17, and the partition wall 18 to the housing 11.
[0053] Preferably, the connecting portion 17 has a through hole 17A that penetrates in the thickness direction. The through hole 17A serves as an air vent when filling with the filler resin 19 and joining the parts. In this way, when joining the connecting portion 17 to the housing 11, the air present in the space between the filler resin 19 and the connecting portion 17 escapes through the through hole 17A. As a result, when filling and joining, the pressure in the space between the filler resin 19 and the connecting portion 17 does not rise excessively, and the connecting portion 17 can be properly joined to the housing 11. Examples of the filler resin 19 include epoxy resin.
[0054] Preferably, the connecting portion 17 has two through holes 17A. One through hole 17A is located on each side of the partition wall 18 of the connecting portion 17. In this way, compared to the case where there is only one through hole 17A, air can escape more easily from the space between the filling resin 19 and the connecting portion 17 when joining the connecting portion 17 to the housing 11. As a result, it is easier to properly join the connecting portion 17 to the housing 11 compared to the case where there is only one through hole 17A.
[0055] Preferably, the two through holes 17A are positioned closer to the partition wall 18 than to the discharge electrode 131. In this way, the two through holes 17A become less conspicuous due to the presence of the partition wall 18. As a result, it becomes more difficult to see the electrical components 12 located inside the housing 11 through the through holes 17A compared to when the through holes 17A are located further away from the partition wall 18. Therefore, the discharge device 1 in which the two through holes 17A are positioned closer to the partition wall 18 than to the discharge electrode 131 has a superior design.
[0056] More preferably, the two through-holes 17A are positioned such that the electrical components 12 located inside the housing 11 cannot be seen through the through-holes 17A. In this way, the electrical components 12 located inside the housing 11 are not visible through the through-holes 17A. Therefore, the discharge device 1 has a more aesthetically pleasing design compared to a case where the electrical components 12 are visible from the outside.
[0057] Preferably, the protective part 141, the connecting part 17, and the partition wall 18 are integrated into a single structure. With such a structure, the protective part 141, the connecting part 17, and the partition wall 18 can be attached to the housing 11 simultaneously. As a result, compared to the case where they are not integrated into a single structure, the protective part 141, the connecting part 17, and the partition wall 18 can be easily attached to the housing 11.
