[0009] [Embodiment] (hair dryer) In the present disclosure, a blower device capable of improving the non-uniformity of the amount of ions blown out together with the wind from a plurality of blowing ports is realized, but first, a hair dryer in the present disclosure, which is an example of a blower device, will be described. In the present disclosure, the term "hair dryer" refers to any device capable of drying hair by a gas flow (wind). Therefore, the hair dryer also includes devices capable of drying other objects (e.g., pet hair) in addition to hair, and devices usable for purposes other than drying hair.

[0010] The hair dryer includes, for example, a device capable of drying hair and blowing gas onto the skin to care for the skin. The temperature of the gas supplied by the hair dryer is not particularly limited. For example, the hair dryer may be capable of supplying at least one of hot air and cold air.

[0011] Here, "cold air" is not defined by an absolute temperature, but refers to air supplied without substantially heating the gas supplied by a heating means such as a heater. In contrast, "hot air" refers to air supplied by heating the gas supplied by a heating means such as a heater.

[0012] The type of gas is not particularly limited. Examples of preferred gases include air, nitrogen, oxygen, argon, and carbon dioxide. These gases are preferably gases in the temperature range in which the hair dryer is used.

[0013] (Overview of Hair Dryer 1) An embodiment of the present invention will be described in detail below. Fig. 1 is a front view showing the appearance of a hair dryer 1 according to this embodiment. Fig. 2 is a cross-sectional view of the hair dryer 1 taken along line AA in Fig. 1.

[0014] 1, a hair dryer (air blower) 1 includes a substantially cylindrical first body (housing) 10 that is held by a user, and a substantially cylindrical second body (housing) 20 that is connected to one end of the first body 10. The shape of the first body 10 is not limited to a substantially cylindrical shape, and may be a polygonal columnar shape as long as it is columnar, and the corners of the polygonal columnar shape may be rounded.

[0015] In the drawings, the direction in which the first main body 10 extends is indicated as the Z direction, the direction perpendicular to the Z direction is indicated as the X direction, and the direction perpendicular to the X and Z directions is indicated as the Y direction.

[0016] The first body 10 has a shape that extends in one direction (Z direction in the figure) and has a gripping part 14 that is gripped by a user. The first body 10 is provided with an operation part 60 that is composed of a plurality of switches. In addition, the second body 20 is connected to one end of the first body 10, and a power cable 80 is connected to the other end of the first body 10.

[0017] An air intake 13 is disposed between the power cable 80 and the grip portion 14 in the first main body 10. The cross-sectional shape of the air intake 13 may be, for example, elongated or dot-shaped.

[0018] The second body 20 has a shape that extends in a direction (Y direction in the figure) that is substantially perpendicular to the direction in which the first body 10 extends, and one end (back side) of the second body 20 is closed. Specifically, the back side of the second body 20 has a double lid structure and is closed by an outer lid 29A and an inner lid 29B. In contrast, a blowing section 25 is disposed at the other end of the second body 20. The blowing section 25 is provided with a plurality of blowing ports 21. Gas passes from the intake port 13 through the first body 10 and the second body 20 to the blowing section 25. In addition, the blowing section 25 is provided with a distance sensor 23 that measures the distance to the object to be dried.

[0019] The distance sensor 23 may be, for example, of a TOF (Time Of Flight) type, and may have a light emitting section and a light receiving section made of semiconductor lasers. However, the distance sensor 23 is not limited to a TOF type, and may be of another type. The distance sensor 23 measures the distance from the position where the distance sensor 23 is provided to an object (at least a part of the human body (e.g., the scalp, hair, etc.) or a member) that exists in front of the distance sensor 23. When the hair is dried by the hair dryer 1, the distance sensor 23 measures the distance to the hair. Note that the distance sensor 23 does not necessarily have to be provided.

[0020] The hair dryer 1 may also include at least one light source. The light source may irradiate light onto the blow-out unit 25 or each of the blow-out outlets 21 to illuminate the blow-out unit 25 or each of the blow-out outlets 21. The light source may irradiate light onto the periphery of the blow-out outlets 21 to illuminate the periphery of the blow-out outlets 21. The blow-out outlets 21 can be clearly indicated by the light source. By including a light source, it becomes easier for the user to know where the multiple blow-out outlets 21 are located, and the user can consciously hold the hair dryer 1 in a position that is aligned with the hair flow direction.

[0021] The color of the light may change depending on the air temperature, such as red for hot air and blue for cold air, or the color may remain the same regardless of the air temperature.

[0022] As shown in Fig. 2, the hair dryer 1 is provided therein with an ion generating unit (ion generating section) 24 that supplies ions to the gas to be blown, and a cylindrical member 40. The ion generating unit 24 is provided on the rear side of the blowing section 25, and has a first electrode 24A and a second electrode 24B (see Fig. 6) that protrude toward the internal space 22 of the second main body 20. Note that reference numeral 22 in Fig. 2 indicates the schematic shape of the internal space by a dashed line, and the cross-sectional view of Fig. 2 shows the schematic overall shape of the internal space including a space portion that is not actually shown.

[0023] Ion generating unit 24 generates, for example, both negative ions and positive ions. First electrode 24A and second electrode 24B of ion generating unit 24 may include a needle-shaped discharge electrode and a ring-shaped induction electrode surrounding the discharge electrode.

[0024] At the first electrode 24A, water molecules in the air are electrically decomposed in a plasma region generated by discharge caused by application of a positive voltage, and hydrogen ions H +are mainly generated. Positive cluster ions H+(HO)m are generated by water molecules in the air coagulating around the generated hydrogen ions H+. Meanwhile, at the second electrode 24B, water molecules in the air are electrically decomposed in a plasma region generated by discharge caused by application of a negative voltage, and oxygen ions O 2- is mainly produced. And the oxygen ions O 2- The negative cluster ions O 2- (H2O)n is formed. The generated positive ions and negative ions are released together with the air blown out from the air outlet 21. Note that each of the first electrode 24A and the second electrode 24B may generate both positive ions and negative ions.

[0025] The ion generating unit 24 according to one embodiment of the present invention is an example of a charged particle supply (generation) mechanism. The charged particle supply (generation) mechanism is a mechanism that supplies (generates) charged particles.

[0026] The term "charged particles" refers to particles that are not electrically neutral, or active species that have been activated to a non-electrically neutral state. Charged particles are not limited to particles that have an electric charge, and include, for example, particles such as atoms and molecules that have no electric charge but have unpaired electrons. Specifically, charged particles include, for example, ions with positive or negative charges, complexes of ions with positive or negative charges, radicals, electrons, protons, and the like.

[0027] The charged particle supply (generation) mechanism may be, for example, a mechanism that supplies (generates) only one type of charged particle, or a mechanism that supplies (generates) multiple types of charged particles. The charged particle supply (generation) mechanism may be, for example, a mechanism that supplies (generates) both positive ions or complexes of positive ions (for example, complexes in which positive ions are coordinated with polar molecules such as water molecules) and negative ions or complexes of negative ions (for example, complexes in which negative ions are coordinated with polar molecules such as water molecules).

[0028] The hair dryer 1 has therein an air passage 12 extending in a first direction (Z direction) 15 from the first body 10 to the second body 20, and an internal space 22 connected to the air passage 12. The cylindrical member 40 is a cylindrical member disposed on the downstream side of the air passage 12, straddling the first body 10 and the second body 20. A heater 41 is housed in the cylindrical member 40.

[0029] In the hair dryer 1, air is drawn into the air passage 12 from the air intake 13, heated by the heater 41 as necessary, and then sent to the internal space 22 by the fan (electric blower) 11, and hot air or cold air is blown out from the air outlet 21 to the object to be dried. Each air outlet 21 opens in a second direction (Y direction) 21a different from the first direction 15 in which the air passage 12 extends. Therefore, hot air or cold air is blown out from each air outlet 21 in the second direction 21a. The angle between the first direction 15 and the second direction 21a may be 90°, but is not limited thereto. A substrate is disposed inside the first body 10 between the fan 11 and the air intake 13, and the substrate is cooled by the air flow generated by the rotation of the fan 11.

[0030] 3 is a block diagram showing the configuration of the main parts of the hair dryer 1. The hair dryer 1 includes a control unit 50 that controls each part of the hair dryer 1. The control unit 50 controls each part in accordance with a signal input operation from an operation unit 60, for example.

[0031] The operation unit 60 includes an ON / OFF switch 61, a one-shot cold air switch 62, a mode change switch 63, and an air volume change switch 64. When the ON / OFF switch 61 is turned on, power is supplied from the power cable 80 to each part of the hair dryer 1. When the ON / OFF switch 61 is turned off, power supply to each part of the hair dryer 1 is stopped. The one-shot cold air switch 62 transmits a signal notifying the control unit 50 that the switch has been operated every time the switch is operated. The control unit 50 alternately controls the heater 41 to be on / off every time the control unit 50 receives a signal from the one-shot cold air switch 62. Note that the control unit 50 may alternately connect and cut off the power from the power cable 80 to the heater 41 every time the one-shot cold air switch 62 is pressed, without going through the control unit 50. The mode change switch 63 and the air volume change switch 64 transmit a signal notifying the control unit 50 that the switch has been operated every time the switch is operated. Control unit 50 controls the rotation speed of fan 11, the heat generation amount of heater 41, and on / off of ion generating unit 24 according to signals from mode change switch 63 and air volume change switch 64.

[0032] (Blowout section 25) 4 is a front view showing the details of blowing section 25. Blowing section 25 is provided on the downstream side in the gas flow direction in second main body 20. Blowing section 25 is provided with two or more blowing outlets 21, and each blowing outlet 21 communicates with internal space 22 of second main body 20.

[0033] 4, in this embodiment, blowing section 25 includes four blowing outlets 21: first blowing outlet 21A, second blowing outlet 21B, third blowing outlet 21C, and fourth blowing outlet 21D. An area of ​​blowing section 25 where no blowing outlet 21 exists is a closed area from which gas is not blown out, and a wall surface section 27 is provided on the central side (inner side) of first to fourth blowing outlets 21A to 21D.

[0034] The centroids of the first to fourth air outlets 21A to 21D on the plane on which air outlet portion 25 is arranged are represented by centroids P1 to P4. A quadrilateral formed by connecting centroids P1 to P4 with straight lines forms a square, and the centroid of the square is represented by centroid C. This centroid C roughly coincides with the center of wall surface portion 27, and distance sensor 23 is provided at the position of centroid C.

[0035] (Structure of internal space 22) Fig. 5 is a BB cross-sectional view of second main body 20 in Fig. 2. Fig. 6 is a CC cross-sectional view of second main body 20 in Fig. 2. Note that, hereinafter, in first direction 15, the direction in which gas flows from air passage 12 to internal space 22 may be referred to as the upper side (the + side in the Z direction), and the opposite side may be referred to as the lower side (the - side in the Z direction).

[0036] 5 and 6, second main body 20 has an internal space 22 connected to air passage 12 formed therein. Internal space 22 is a space in the hollow portion of second main body 20 excluding air passage 12. Second main body 20 has a partition wall portion 28 that defines air passage 12 in the hollow portion of second main body 20 and configures the downstream side of air passage 12. Partition wall portion 28 is annular, and holds the outer periphery of tubular member 40.

[0037] When the YZ plane passing through the center of the air passage 12 is defined as a virtual plane 43, the internal space 22 has a shape symmetrical with respect to the virtual plane 43. The internal space 22 includes a ridge 22A that is convex toward the inside of the internal space 22 at a position where the virtual plane 43 passes. The internal space 22 also includes curved surfaces whose curvature changes gently from both sides of the ridge 22A. Specifically, the internal space 22 includes a first curved surface 22B that is convexly curved toward the outside of the internal space 22 and connected to the partition wall 28 on one side S1 with respect to the virtual plane 43. The internal space 22 also includes a second curved surface 22C that is convexly curved toward the outside of the internal space 22 and connected to the partition wall 28 on the other side S2 with respect to the virtual plane 43. This allows the flow of air in the internal space 22 to change gently, and the air can be blown with little pressure loss.

[0038] As shown in FIG. 5, the rear side of the internal space 22 of the second main body 20 has a first hole 26A and a second hole 26B in an area facing the first electrode 24A and the second electrode 24B of the ion generating unit 24. The first hole 26A and the second hole 26B are used during maintenance such as cleaning of the first electrode 24A and the second electrode 24B. The first hole 26A faces the first electrode 24A, and the second hole 26B is provided at a position facing the second electrode 24B. The first hole 26A and the second hole 26B are formed penetrating the wall surface on the rear side that forms the internal space 22. As described above, the rear side of the second main body 20 has a double lid structure, and the inner lid 29B is detachable by, for example, a screw 29C (see FIG. 2). The first hole 26A and the second hole 26B are closed by the inner lid 29B except during maintenance of the first electrode 24A and the second electrode 24B. This prevents air from leaking from the first hole 26A and the second hole 26B when the hair dryer 1 is in use. The inner lid 29B may be a single component that covers both the first hole 26A and the second hole 26B. Alternatively, an inner lid 29B may be provided separately for each hole, such as an inner lid 29B that covers only the first hole 26A and an inner lid 29B that covers only the second hole 26B.

[0039] As shown in FIG. 6, the first to fourth air outlets 21A to 21D are provided at four corners on the front side of the internal space 22 of the second main body 20 so as to be symmetrical with respect to the imaginary plane 43. Specifically, the first air outlet 21A is located on one side S1 of the partition wall portion 28 and above the partition wall portion 28, and the second air outlet 21B is located on the other side S2 of the partition wall portion 28 and above the partition wall portion 28. The third air outlet 21C is located below the second air outlet 21B and on the other side S2 of the partition wall portion 28, and the fourth air outlet 21D is located below the first air outlet 21A and on one side S1 of the partition wall portion 28. Furthermore, on the front side of the internal space 22 of the second main body 20, the first electrode 24A is located on one side S1, and the second electrode 24B is located on the other side S2. The first electrode 24A and the second electrode 24B are disposed symmetrically with respect to the imaginary plane 43 with a gap therebetween across the imaginary plane 43.

[0040] Here, the hair dryer 1 includes a first air guide member 31 on the front side of the internal space 22 of the second body 20, which guides a portion of the gas that has flowed from the air passage 12 into the internal space 22 and passed through the first electrode 24A to the second air outlet 21B side (the other side S2). The hair dryer 1 also includes a second air guide member 32 which guides a portion of the gas that has flowed from the air passage 12 into the internal space 22 and passed through the second electrode 24B to the first air outlet 21A side (the one side S1).

[0041] The first air guide member 31 and the second air guide member 32 are arranged symmetrically with respect to the imaginary plane 43, with a gap therebetween. The first air guide member 31 and the second air guide member 32 are plate-like members that protrude and extend from the inner wall of the internal space 22 downstream of the first electrode 24A and the second electrode 24B. More specifically, the first air guide member 31 and the second air guide member 32 are plate-like members that protrude and extend from the inner wall of the internal space 22 on the side where the first electrode 24A and the second electrode 24B are arranged, that is, the front side, and protrude further than the first electrode 24A and the second electrode 24B. The first air guide member 31 and the second air guide member 32 may or may not reach the inner wall of the internal space 22 on the rear side that faces the inner wall of the internal space 22 on the front side where the first electrode 24A and the second electrode 24B are arranged. The first electrode 24A is located on the wind guide surface side (i.e., the surface on the wind passage 12 side) of the first wind guide member 31, and the first air outlet 21A is located on the rear side thereof. The second electrode 24B is located on the wind guide surface side (i.e., the surface on the wind passage 12 side) of the second wind guide member 32, and the second air outlet 21B is located on the rear side thereof. The first wind guide member 31 and the second wind guide member 32 are arranged with their wind guide surfaces inclined so that when each wind guide surface is extended, they intersect above the first wind guide member 31 and the second wind guide member 32. The ridge portion 22A is located downstream of the first wind guide member 31 and the second wind guide member 32, in other words, on the opposite side of the wind passage 12 from the first wind guide member 31 and the second wind guide member 32.

[0042] A part of the gas that has passed through the first electrode 24A is guided to the other side S2 by the first air guide member 31. Therefore, the amount of ions generated by the first electrode 24A that are blown out from the second air outlet 21B and the third air outlet 21C arranged on the other side S2 increases. On the other hand, a part of the gas that has passed through the second electrode 24B is guided to the one side S1 by the second air guide member 32. Therefore, the amount of ions generated by the second electrode 24B that are blown out from the first air outlet 21A and the fourth air outlet 21D arranged on the one side S1 increases. Therefore, the difference in the amount of ions blown out from the first to fourth air outlets 21A to 21D becomes small, and the non-uniformity of the amount of ions blown out from each air outlet 21 can be improved. When the first electrode 24A generates positive ions and the second electrode 24B generates negative ions, the difference in the amount of positive and negative ions blown out from the first to fourth air outlets 21A to 21D becomes small, and the non-uniformity of the amount of positive and negative ions blown out from each air outlet 21 can be improved.

[0043] On the other hand, in the absence of the first air guide member 31, most of the gas that has passed through the first electrode 24A flows to one side S1, and the gas that has passed through the first electrode 24A does not easily flow to the other side S2. Similarly, in the absence of the second air guide member 32, most of the gas that has passed through the second electrode 24B flows to the other side S2, and the gas that has passed through the second electrode 24B does not easily flow to the one side S1. This results in uneven amounts of ions being blown out from each air outlet 21. For example, when the first electrode 24A generates positive ions and the second electrode 24B generates negative ions, the difference between the amounts of positive and negative ions blown out from the first to fourth air outlets 21A to 21D becomes large. According to this embodiment, it is possible to improve such unevenness in the amounts of positive and negative ions being blown out from each air outlet 21.

[0044] The gas that has passed through the first electrode 24A means the gas that has passed around the first electrode 24A, in other words, the gas that has passed around the area where the first electrode 24A is disposed. Similarly, the gas that has passed through the second electrode 24B means the gas that has passed around the second electrode 24B, in other words, the gas that has passed around the area where the second electrode 24B is disposed.

[0045] The first air guide member 31 may be located downstream of the first electrode 24A in the flow direction (airflow direction) of the gas from the air passage 12 to the first air outlet 21A. This allows a portion of the gas that has passed through the first electrode 24A to be suitably guided to the second air outlet 21B side by the first air guide member 31 located downstream of the first electrode 24A. Similarly, the second air guide member 32 may be located downstream of the second electrode 24B in the flow direction of the gas from the air passage 12 to the second air outlet 21B. This allows a portion of the gas that has passed through the second electrode 24B to be suitably guided to the first air outlet 21A side by the second air guide member 32 located downstream of the second electrode 24B.

[0046] The first electrode 24A and the first air guide member 31 may be disposed in the extended region 16, which is a virtual region obtained by extending the air passage 12. The first electrode 24A and the first air guide member 31 may be disposed side by side in the first direction 15 in a region on one side S1 in the extended region 16. This makes it easier for the first air guide member 31 to guide a portion of the gas that has passed through the first electrode 24A to the second air outlet 21B side. Similarly, the second electrode 24B and the second air guide member 32 may be disposed in the extended region 16, which is a virtual region obtained by extending the air passage 12. The second electrode 24B and the second air guide member 32 may be disposed side by side in the first direction 15 in a region on the other side S2 in the extended region 16. This makes it easier for the second air guide member 32 to guide a portion of the gas that has passed through the second electrode 24B to the first air outlet 21A side.

[0047] The first air guide member 31 may include a first end 31A on one side S1 and a second end 31B on the other side S2, and the second end 31B may be disposed at a position farther away from the air passage 12 than the first end 31A, i.e., above the first end 31A. This allows the first air guide member 31 to be disposed tilted toward the other side S2, making it easier for the first air guide member 31 to guide a portion of the gas that has passed through the first electrode 24A to the second outlet 21B. Similarly, the second air guide member 32 may include a first end 32A on the other side S2 and a second end 32B on one side S1, and the second end 32B may be disposed at a position farther away from the air passage 12 than the first end 32A, i.e., above the first end 32A. As a result, the second air guide member 32 is disposed inclined toward one side S1, so that a portion of the gas that has passed through the second electrode 24B can be easily guided toward the first air outlet 21A by the second air guide member 32. In this embodiment, the first end 31A and the first end 32A are provided at the same height in the first direction (Z direction). The second end 31B and the second end 32B are provided at the same height in the first direction (Z direction). The first end 31A and the first end 32A may be located outside the extension region 16, which is a virtual region obtained by extending the air passage 12.

[0048] Furthermore, the first air guide member 31 may be disposed at a position closer to the air passage 12 than the first air outlet 21A. This makes it easier for the first air guide member 31 to guide a portion of the gas that has passed through the first electrode 24A to the second air outlet 21B side before it reaches the first air outlet 21A from the air passage 12. Similarly, the second air guide member 32 may be disposed at a position closer to the air passage 12 than the second air outlet 21B. This makes it easier for the second air guide member 32 to guide a portion of the gas that has passed through the second electrode 24B to the first air outlet 21A side before it reaches the second air outlet 21B from the air passage 12.

[0049] In addition, when the end of the first air outlet 21A located on the air passage 12 side in the first direction 15 is the lower end (air passage side end) 21E, the position of the first end 31A of the first air guide member 31 in the first direction 15 may be the same as the lower end 21E or closer to the air passage 12 than the lower end 21E. This makes it easier for the first air guide member 31 to guide a part of the gas that has passed through the first electrode 24A to the second air outlet 21B side before it reaches the first air outlet 21A from the air passage 12. Similarly, when the end of the second air outlet 21B located on the air passage 12 side in the first direction 15 is the lower end (air passage side end) 21F, the position of the first end 32A of the second air guide member 32 in the first direction 15 may be the same as the lower end 21F or closer to the air passage 12 than the lower end 21F. This makes it easier for a portion of the gas that has passed through second electrode 24B to be guided by second air guide member 32 toward first air outlet 21A before reaching second air outlet 21B from air passage 12.

[0050] (Gas flow in the internal space 22) Fig. 7 is a cross-sectional view showing the flow of air currents in the internal space 22 shown in Fig. 6. As shown in Fig. 6, of the air currents F flowing from the air passage 12 into the internal space 22, a part of the first air currents F1 that have passed through the first electrode 24A is guided by the first air guide member 31 to the other side S2 where the second air outlet 21B and the third air outlet 21C are located, generating a second air current F2. Also, of the air currents F that have flowed from the air passage 12 into the internal space 22, a part of the third air currents F3 that have passed through the second electrode 24B is guided by the second air guide member 32 to the one side S1 where the first air outlet 21A and the fourth air outlet 21D are located, generating a fourth air current F4.

[0051] In this way, the first air guide member 31 generates a second air flow F2 that branches off from the first air flow F1 flowing on the one side S1 and heads toward the other side S2. This second air flow F2 passes through the second air outlet 21B and flows along the second curved surface 22C to the third air outlet 21C. In this process, ions generated at the first electrode 24A are blown out together with the gas from the second air outlet 21B and the third air outlet 21C. In addition, the second air guide member 32 generates a fourth air flow F4 that branches off from the third air flow F3 flowing on the other side S2 and heads toward the one side S1. This fourth air flow F4 passes through the first air outlet 21A and flows along the first curved surface 22B to the fourth air outlet 21D. In this process, ions generated at the second electrode 24B are blown out together with the gas from the first air outlet 21A and the fourth air outlet 21D. This reduces the difference in the amount of positive ions and negative ions blown out from the first to fourth air outlets 21A to 21D, and improves the non-uniformity of the amount of ions blown out from each air outlet 21. When the air guide surface (i.e., the surface on the air passage 12 side) of the first air guide member 31 is virtually extended toward the ridge 22A, it is preferable that the virtual extended surface of the air guide surface of the first air guide member 31 contacts the ridge 22A or is located below the ridge 22A. In this way, the second airflow F2 easily flows toward the second air outlet 21B. Similarly, when the air guide surface (i.e., the surface on the air passage 12 side) of the second air guide member 32 is virtually extended toward the ridge 22A, it is preferable that the virtual extended surface of the air guide surface of the second air guide member 32 contacts the ridge 22A or is located below the ridge 22A. In this way, the fourth airflow F4 easily flows toward the first air outlet 21A.

[0052] [Effects of Hair Dryer 1] As described above, the hair dryer 1 of this embodiment comprises an internal space 22 connected to an air passage 12 extending in a first direction 15, a second main body having an air outlet 21 including a first air outlet 21A located on one side S1 and a second air outlet 21B located on the other side S2 of a virtual plane 43 passing through the center of the air passage 12, an ion generating unit 24 disposed in the internal space 22 and including a first electrode 24A located on one side S1 and a second electrode 24B located on the other side S2, and a first air guide member 31 that guides a portion of the gas that flows from the air passage 12 into the internal space 22 and passes through the first electrode 24A toward the second air outlet 21B.

[0053] In the hair dryer 1, a part of the gas that has passed through the first electrode 24A is guided toward the second air outlet 21B by the first air guide member 31, and therefore the amount of ions generated by the first electrode 24A and contained in the air blown out from the second air outlet 21B increases. Therefore, according to this embodiment, the difference between the amount of ions blown out from the first air outlet 21A and the second air outlet 21B becomes smaller, and the non-uniformity in the amount of ions blown out from each air outlet can be improved.

[0054] Moreover, the hair dryer 1 according to this embodiment further includes a second air guide member 32 that guides a part of the gas that has flowed from the air passage 12 into the internal space 22 and passed through the second electrode 24B toward the first air outlet 21A.

[0055] In the hair dryer 1, a part of the gas that has passed through the second electrode 24B is guided toward the first air outlet 21A by the second air guide member 32, and therefore the amount of ions generated by the second electrode 24B and contained in the air blown out from the first air outlet 21A increases. Therefore, according to this embodiment, the difference between the amount of ions blown out from the first air outlet 21A and the second air outlet 21B is further reduced, and the non-uniformity in the amount of ions blown out from each air outlet can be further improved.

[0056] 〔summary〕 The air blowing device (hair dryer 1) according to aspect 1 of the present invention comprises a housing having an internal space connected to an air passage extending in a first direction, and an air outlet communicating with the internal space, including a first air outlet located on one side of an imaginary plane passing through the center of the air passage and a second air outlet located on the other side, an ion generating section (ion generating unit 24) disposed in the internal space and including a first electrode located on the one side and a second electrode located on the other side, and a first air guide member that guides a portion of the gas that flows from the air passage into the internal space and passes through the first electrode toward the second air outlet side.

[0057] In the above configuration, a portion of the gas that has passed through the first electrode is guided toward the second outlet by the first air guide member, and the amount of ions generated by the first electrode that is contained in the air blown out from the second outlet increases. Therefore, with the above configuration, the difference in the amount of ions blown out from the first outlet and the second outlet becomes smaller, and the non-uniformity in the amount of ions blown out from each outlet can be improved.

[0058] In the air blower device according to a second aspect of the present invention, in the first aspect, the first air guide member may be located downstream of the first electrode in a flow direction of the gas from the air passage to the first air outlet.

[0059] According to the above configuration, since the first air guide member is located downstream of the first electrode, a portion of the gas that has passed through the first electrode can be suitably guided toward the second outlet by the first air guide member located downstream of the first electrode.

[0060] In the air blower according to a third aspect of the present invention, in the first or second aspect, the first electrode and the first air guide member may be disposed in an extended region that is a virtual region obtained by extending the air passage in the internal space.

[0061] According to the above configuration, the first electrode and the first air guide member are disposed in the area where gas flows from the air passage into the internal space, making it easier for a portion of the gas that has passed through the first electrode to be guided toward the second outlet by the first air guide member.

[0062] A fourth aspect of the present invention relates to the air blower device of the third aspect, and the first electrode and the first air guide member may be arranged side by side in the first direction.

[0063] According to the above configuration, the first electrode and the first air guide member are arranged next to each other in the direction in which gas flows from the air passage into the internal space, making it easier for a portion of the gas that has passed through the first electrode to be guided toward the second outlet by the first air guide member.

[0065] According to this configuration, since the first air guide member is disposed inclined toward the other side, a portion of the gas that has passed through the first electrode can be easily guided toward the second outlet by the first air guide member.

[0066] A sixth aspect of the present invention relates to an air blower device in any one of the first to fifth aspects, wherein the first air guide member is disposed at a position closer to the air passage than the first air outlet.

[0071] In the above configuration, a portion of the gas that has passed through the second electrode is guided toward the first outlet by the second air guide member, and therefore the amount of ions generated by the second electrode and contained in the air blown out from the first outlet increases. Therefore, with the above configuration, the difference between the amount of ions blown out from the first outlet and the second outlet becomes smaller, and the non-uniformity of the amount of ions blown out from each outlet can be improved.
