[Modes for carrying out the invention] 【0015】 The following describes several embodiments of the present invention, including Embodiments 1 to 6 and their design modifications. It should be noted that the components of the embodiments and design modifications described below can be combined with each other, as long as they do not contradict each other. Furthermore, the materials, shapes, dimensions, numbers, and arrangements of the components in each embodiment and design modification described below are merely examples, and can be arbitrarily modified as long as similar functions can be achieved. [Examples] 【0016】 The following describes a wearable blower according to multiple embodiments of the present invention, including Embodiment 1 and its design modifications, with reference to Figures 1A to 3A. Figures 1A to 2B show the wearable blower D1 of Embodiment 1. Figure 3A shows the first design modification of the wearable blower D1 of Embodiment 1. Figures 2A and 3A show the X-X' direction (waist width direction) and the Z-Z' direction (up and down direction). The X-X' direction includes the X direction (one side of the waist width direction) and the X' direction (the other side of the waist width direction). The Z-Z' direction intersects the X-X' direction and includes the Z direction (up) and the Z' direction (down). Figure 2b shows the Z-Z' direction and the Y-Y' direction (inside and out). The Y-Y' direction is substantially perpendicular to the Z-Z' direction and does not lie on the plane where the X-X' and Z-Z' directions are located. The Y-Y' direction includes the Y direction (inward direction) and the Y' direction (outward direction). 【0017】 The wearable fan D1 is equipped with a bag 100 (see Figures 1A to 3A). The bag 100 can be any bag that can be attached to the user's waist H (see Figures 2A and 2B), and may be a waist pouch, hip bag, or body bag. The bag 100 can be configured to have a bag section 110 and belt sections 121 and 122. The belt sections 121 and 122 extend from both ends of the bag section 110, and buckles are provided at their ends. The bag 100 is attached to the user's waist by bringing the bag section 110 into contact with the person's waist H, wrapping the belt sections 121 and 122 around the user's waist H, and connecting the buckles on the belt sections 121 and 122. For the sake of explanation, the state in which the bag 100 is wrapped around and attached to the user's waist H will be referred to as the "attached state". The portion of the waist H on the X-direction side relative to the spine is called the "first transverse portion Ha," the portion of the waist H on the X'-direction side relative to the spine is called the "second transverse portion Hb," and the portion of the waist H between the first transverse portion Ha and the second transverse portion Hb is called the "central portion Hc." Furthermore, the side of the user's abdomen on the X-direction side is called the "first transverse portion Fa," and the side of the user's abdomen on the X'-direction side (opposite the first transverse portion Fa) is called the "second transverse portion Fb." The Y-direction is the direction in which the bag portion 110 contacts the user when the bag 100 is attached to the user's waist H, and the Y'-direction is the opposite direction of the Y'-direction. In Figure 3A, the belt portions 121 and 122 are omitted from the illustration. 【0018】 The bag portion 110 has an upper portion 111, an inner portion 112, an outer portion 113, a bottom portion 114, at least one exhaust port 101, and at least one mounting hole 102. The upper portion 111, inner portion 112, outer portion 113, and bottom portion 114 may be made of a flexible fabric such as nylon, vinyl and / or polyester, or a high-density woven fabric in which flexible threads are woven at high density, but are not limited thereto. One or both sides of the fabric may be coated or laminated with a resin film such as a polyurethane resin (for example, thermoplastic polyurethane (TPU)), polyester resin, or polytetrafluoroethylene resin, or it may be PVC (polyvinyl chloride) processed. 【0019】 The bag portion 110 further has, for example, one of the following configurations (1) to (3). 【0020】 (1) The upper part 111 is located on the Z-direction side of the bag part 110 and is curved in a substantially arc shape so as to conform to the user's waist H when worn (see Figures 1A to 2B). The upper part 111 has a first part 111a, a second part 111b, and a third part 111c. The first part 111a is the X-direction side portion of the upper part 111 (for example, the X-direction end of the upper part 111 (see Figures 1A to 2B) or its X'-direction side portion (not shown)). The second part 111b is the X'-direction side portion of the upper part 111 (for example, the X'-direction end of the upper part 111 (see Figures 1A to 2B) or its X-direction side portion (not shown)). The third part 111c is the intermediate part of the upper part 111 between the first part 111a and the second part 111b. The first part 111a may extend in an oblique direction including components in the X and Z' directions (it may be inclined downwards) when installed, but it does not have to extend in such an oblique direction (it does not have to be inclined). The second part 111b may extend in an oblique direction including components in the X' and Z' directions (it may be inclined downwards) when installed, but it does not have to extend in such an oblique direction (it does not have to be inclined). When the first part 111a and the second part 111b are inclined, when installed, the upper part 111 is configured such that the third part 111c forms the upper side of a roughly trapezoid, the first part 111a forms the first hypotenuse of the roughly trapezoid, and the second part 111b forms the second hypotenuse of the roughly trapezoid. When the first part 111a and the second part 111b are not inclined, the upper part 111, the first part 111a, the second part 111b, and the third part 111c extend roughly horizontally when installed. When worn, the first part 111a is positioned near at least one of the first lateral part Ha and the first lateral part Fa of the waist H, the second part 111b is positioned near at least one of the second lateral part Hb and the second lateral part Fb of the waist H, and the third part 111c is positioned near the central part Hc of the waist H (see Figures 2A and 2B). The upper part 111 further has an inner end on the Y direction side and an outer end on the Y' direction side. 【0021】 At least one exhaust port 101 is provided in the upper portion 111, penetrates the upper portion 111, and opens in a direction including at least a component in the Z direction. At least one exhaust port 101 includes at least one first exhaust port 101a. At least one first exhaust port 101a is one or more, provided in the first portion 111a of the upper portion 111, penetrates the first portion 111a, and opens in a direction including at least a component in the Z direction. If the first portion 111a is inclined, one or more first exhaust ports 101a open in an oblique direction including components in the Z and X directions. At least one exhaust port 101 may further include at least one second exhaust port 101b. At least one second exhaust port 101b is one or more, provided in the second portion 111b of the upper portion 111, penetrates the second portion 111b, and opens in a direction including at least a component in the Z direction. If the second section 111b is inclined, one or more second exhaust ports 101b open in an oblique direction including components in the Z and X' directions. At least one exhaust port 101 may further include at least one third exhaust port 101c. At least one third exhaust port 101c is one or more, provided in the third section 111c of the upper section 111, penetrating the third section 111c and opening in a direction including at least a component in the Z direction. Note that at least one second exhaust port 101b and / or at least one third exhaust port 101c are optional. 【0022】 The inner portion 112 is the part of the bag portion 110 that comes into contact with the user's waist H when worn, or is positioned opposite to it at a distance. The inner portion 112 has an upper end and a lower end. The upper end of the inner portion 112 is connected to the inner end of the upper portion 111 by sewing or adhesive, and the inner portion 112 hangs down from the inner end of the upper portion 111. The upper end of the inner portion 112 is curved in an arc shape according to the shape of the inner end of the upper portion 111, and consequently the inner portion 112 itself is also curved in an arc shape according to the shape of the inner end of the upper portion 111. A pocket may be provided in the inner portion 112. The pocket can accommodate a cooling pack or a Peltier element (not shown). The pocket is optional. The cooling pack or Peltier element may be placed inside the bag portion 110. The cooling pack or Peltier element is optional. 【0023】 The outer portion 113 is the part of the bag portion 110 located on the Y' direction side relative to the inner portion 112. The outer portion 113 has an upper end and a lower end. The upper end of the outer portion 113 is connected to the outer end of the upper portion 111 by sewing or adhesive. The upper end of the outer portion 113 is curved in an arc along with the outer end of the upper portion 111, and consequently, the outer portion 113 itself is also curved in an arc according to the shape of the outer end of the upper portion 111. The outer portion 113 may, but is not limited to, be provided with an openable and closable wire fastener. The wire fastener may be provided on the upper portion 111 or the inner portion 112 instead of the outer portion 113. 【0024】 The bottom portion 114 is located on the Z' side of the bag portion 110, positioned on the Z' side relative to the upper portion 111, and is curved in a roughly arc shape so as to conform to the user's waist H when worn (see Figures 1A to 2B). The bottom portion 114 has an inner end on the Y side and an outer end on the Y' side. The inner end of the bottom portion 114 is connected to the lower end of the inner portion 112 by sewing or adhesive, and the outer end of the bottom portion 114 is connected to the lower end of the outer portion 113 by sewing or adhesive. The Y-Y' dimension of the bottom portion 114 can be made larger than the Y-Y' dimension of the upper portion 111. In this case, when worn, the outer portion 113 extends diagonally from the outer end of the upper portion 111 to the outer end of the bottom portion 114, including components in the Y' and Z' directions (it slopes downwards). The Y-Y' dimension of the bottom portion 114 can be approximately the same as the Y-Y' dimension of the top portion 111. In this case, the outer portion 113 extends in the Z-Z' direction from the outer end of the top portion 111 to the outer end of the bottom portion 114 when installed. The Z-Z' dimension of the outer portion 113 can be larger than the Z-Z' dimension of the inner portion 112. In this case, the bottom portion 114 extends in a diagonal direction including components in the Y' and Z' directions from the lower end of the inner portion 112 to the lower end of the outer portion 113 when installed (it slopes downwards). The Z-Z' dimension of the outer portion 113 may be approximately the same as the Z-Z' dimension of the inner portion 112. In this case, the bottom portion 114 extends approximately horizontally from the lower end of the inner portion 112 to the lower end of the outer portion 113 when installed. 【0025】 The bottom portion 114 has at least one support portion. The at least one support portion is located on the Z' side relative to the third portion 111c of the upper portion 111. That is, the at least one support portion forms a part of the bottom portion 114 located on the Z' side relative to the third portion 111c. The at least one support portion includes a first support portion 114a. The first support portion 114a is a part of the bottom portion 114 located on the Z' side relative to the third portion 111c, and in the installed state extends in an oblique direction including components in the X and Z' directions (slopes downward). If the first portion 111a of the upper portion 111 is inclined, the inclination angle of the first support portion 114a and the inclination angle of the first portion 111a of the upper portion 111 may be approximately the same or different. In other words, the inclination direction in which the first support portion 114a extends and the inclination direction in which the first portion 111a of the upper portion 111 extends may be the same or they may be different. 【0026】 At least one support portion may further include a second support portion 114b. The second support portion 114b is another part of the bottom portion 114 on the X' side relative to the first support portion 114a, located on the Z' side relative to the third portion 111c, and extends in an oblique direction including components in the X' and Z' directions when installed (sloping downwards). If the second portion 111b of the upper portion 111 is inclined, the inclination angle of the second support portion 114b and the inclination angle of the second portion 111b of the upper portion 111 may be approximately the same or different. That is, the inclination direction in which the second support portion 114b extends and the inclination direction in which the second portion 111b of the upper portion 111 extends may be the same or different. If a first support portion 114a and a second support portion 114b are provided, the first support portion 114a and the second support portion 114b may be in a substantially V-shape that is convex in the Z direction (see Figures 1A to 2B). Alternatively, if a first support portion 114a and a second support portion 114b are provided, the bottom portion 114 may further have an intermediate portion between the first support portion 114a and the second support portion 114b, where the intermediate portion forms the upper side of a substantially trapezoid, the first support portion 114a forms the first hypotenuse of the substantially trapezoid, and the second support portion 114b forms the second hypotenuse of the substantially trapezoid (not shown). If the bottom portion 114 is inclined in an oblique direction including components in the Y' and Z' directions when installed, the first support portion 114a and the second support portion 114b are also inclined in an oblique direction including components in the Y' and Z' directions. 【0027】 At least one support portion may further include a third support portion, which is not shown. The third support portion is an intermediate portion of the bottom portion 114 between the first support portion 114a and the second support portion 114b, and is located on the Z' side relative to the third portion 111c. The second support portion 114b and / or the third support portion are optional. 【0028】 At least one mounting hole 102 includes a first mounting hole 102a. The first mounting hole 102a is provided in the first support portion 114a and penetrates the first support portion 114a in an oblique direction including components in the Z and X directions. 【0029】 If a second support portion 114b is provided, at least one mounting hole 102 further includes a second mounting hole 102b. The second mounting hole 102b is provided in the second support portion 114b and penetrates the second support portion 114b in an oblique direction including components in the Z direction and the X' direction. 【0030】 If a third support portion is provided, at least one mounting hole 102 further includes a third mounting hole (not shown). The third mounting hole is provided in the third support portion and penetrates the third support portion in a direction including a component in the Z direction. The second mounting hole 102b is optional, along with the second support portion 114b. The third mounting hole is optional, along with the third support portion. 【0031】 (2) The bag portion 110 differs from the bag portion 110 having the configuration of (1) above in that the inner ends of the upper portion 111 and the bottom portion 114 are curved in a substantially arc shape so as to conform to the user's waist H when worn, while the outer ends of the upper portion 111 and the bottom portion 114 extend in the X-X' direction, otherwise it can have the same configuration as the bag portion 110 having the configuration of (1) above (not shown). 【0032】 (3) The bag portion 110 is substantially cylindrical in shape with an upper portion 111, an inner portion 112, an outer portion 113, and a bottom portion 114 extending in the X-X' direction, and the bag portion 110 further has a pair of side portions 115, and the pair of side portions 115 are configured to close the openings on both sides that are partitioned by the upper portion 111, the inner portion 112, the outer portion 113, and the bottom portion 114. Except for this difference, it is possible to have the same configuration as the bag portion 110 having the configuration of (1) above (see Figure 3A). In this case as well, the first portion 111a and / or the second portion 111b of the upper portion 111 may or may not be inclined as described above. The bottom portion 114 may have a first support portion 114a, or it may have a first support portion 114a and a second support portion 114b. 【0033】 The bag portion 110 may be composed of one of the above-mentioned fabrics or high-density woven materials for the upper portion 111 and the outer portion 113, and / or the bottom portion 114 and the inner portion 112 may be composed of one of the above-mentioned fabrics or high-density woven materials. The bag portion 110 may be composed of one of the above-mentioned fabrics or high-density woven materials for the upper portion 111 and the inner portion 112, and / or the bottom portion 114 and the outer portion 113 may be composed of one of the above-mentioned fabrics or high-density woven materials. 【0034】 When worn, the bag portion 110 is positioned such that at least one exhaust port 101 of the upper portion 111 is located between the user's waist H and the back of the user's jacket. The bag portion 110 may, but is not limited to, be positioned between the user's waist H and the back of the user's jacket when worn. In Figures 2A and 2B, the lower end of the back of the jacket is shown tucked up for the convenience of showing the bag portion 110, but in actual use, the lower end of the back of the jacket is located on the Y' side relative to the bag portion 110. 【0035】 The mounted blower D1 further comprises at least one fan 200. The at least one fan 200 has a rotating blade 210, a motor (not shown), a housing 220, and a fixing device (not shown). The housing 220 has a cylindrical portion, an outer guard portion, an inner guard portion, and a flange. The outer diameter of the cylindrical portion is approximately the same as or slightly smaller than the diameter of at least one mounting hole 102. This cylindrical portion is inserted into at least one mounting hole 102 from the outside. A threaded portion is formed on the outer circumferential surface of the cylindrical portion. The flange extends from the outer circumferential surface of the cylindrical portion and abuts from the outside the periphery of at least one mounting hole 102 of at least one support portion. The outer guard portion is a grid formed to close the outer opening of the cylindrical portion. The inner guard portion is a grid formed to close the inner opening of the cylindrical portion. The rotating blade 210 and the motor are held within a housing space partitioned by the cylindrical portion, outer guard portion, and inner guard portion of the housing 220. The rotating blades 210 are connected to the motor's rotation shaft directly or indirectly via gears or the like within the housing space, and are rotatable. The fixing device is a cylindrical body with a threaded portion formed on its inner circumference, which is inserted into the bag portion 110 by opening the wire fastener, and is screwed into the cylindrical portion of the housing 220 within the bag portion 110, and abuts from the inside the periphery of at least one mounting hole 102 of at least one support portion. In this way, at least one fan 200 is fixed to the periphery of at least one mounting hole 102 by clamping the periphery of at least one mounting hole 102 between the flange and the fixing device. In the fixed state, the outer guard portion and the flange are exposed from at least one mounting hole 102. 【0036】 In this way, at least one fan 200 is exposed through at least one mounting hole 102. Meanwhile, the cylindrical part, rotating blades 210, motor, and fixtures of at least one fan 200 are housed within the bag portion 110. When the motor of at least one fan 200 is driven and the rotating blades 210 rotate, air is introduced into the bag portion 110 and expelled through at least one exhaust port 101. The motor is turned on / off by a switch. 【0037】 At least one fan 200 includes a first fan 200a. The first fan 200a has the configuration described above and is mounted and supported in the first mounting hole 102a of the first support portion 114a as described above. Because the first support portion 114a extends in an oblique direction including components in the X and Z' directions, the airflow direction Wa (see Figures 1J and 3A) of at least a portion of the air blown by the first fan 200a supported by the first support portion 114a (i.e., all or a portion of the air blown by the first fan 200a) is directed toward the first portion 111a of the upper portion 111 of the bag portion 110. More specifically, at least one of the multiple gaps formed between the grids of the inner guard portion of the first fan 200a is directed toward the first portion 111a of the upper portion 111. The airflow direction Wa of a portion of the air blown by the first fan 200a supported by the first support portion 114a (all the air being blown) may be directed toward the first portion 111a of the upper portion 111 of the bag portion 110, and the airflow direction Wa of another portion of the air may be directed toward the X-direction side portion of the third portion 111c of the upper portion 111 of the bag portion 110. 【0038】 If a second support portion 114b and a second mounting hole 102b are provided, at least one fan 200 further includes a second fan 200b. The second fan 200b has the configuration described above and is mounted and supported in the second mounting hole 102b of the second support portion 114b as described above. Because the second support portion 114b extends in an oblique direction including components in the X' and Z' directions, the airflow direction Wb (see Figures 1J and 3A) of at least some of the air blown by the second fan 200b supported by the second support portion 114b (i.e., all or some of the air blown by the second fan 200b) is directed toward the second portion 111b of the upper portion 111 of the bag portion 110. More specifically, at least one of the multiple gaps formed between the grids of the inner guard portion of the second fan 200b is directed toward the second portion 111b of the upper portion 111. The airflow direction Wb of a portion of the air blown by the second fan 200b supported by the second support portion 114b (all the air being blown) may be directed toward the second portion 111b of the upper portion 111 of the bag portion 110, and the airflow direction Wb of another portion of the air may be directed toward the portion of the third portion 111c of the upper portion 111 of the bag portion 110 that is on the X' side. 【0039】 If a third support portion and a third mounting hole are provided, at least one fan 200 further includes a third fan (not shown). The third fan has the configuration described above and is mounted and supported in the third mounting hole of the third support portion as described above. The direction of airflow from the third fan supported by the third support portion is directed toward the third portion 111c of the upper portion 111 of the bag portion 110. More specifically, at least one of the multiple gaps formed between the grids of the inner guard portion of the third fan is directed toward the third portion of the upper portion 111. 【0040】 The wearable blower D1 may further include at least one battery (not shown). Power is supplied from at least one battery to the motor of at least one fan 200 by at least one battery being electrically connected to at least one fan 200. At least one battery is housed in the bag portion 110. At least one battery can be housed in the bag portion 110 by opening the wire fastener. At least one battery may be multiple, or it may be omitted. If omitted, an external battery may be used to power at least one fan 200. 【0041】 The wearable fan D1 may further include at least one anti-suction member 300. The at least one anti-suction member 300 is one or more in number and is provided protruding from the bag portion 110 or at least one fan 200 and is configured to prevent the back of the user's upper garment from being sucked in by at least one fan 200. For example, one or more anti-suction members 300 have at least one of the following configurations (a) to (f). 【0042】 (a) One or more anti-suction members 300 are flanges extending from the lower end of the outer portion 113 of the bag portion 110 in a direction including a component in the Z' direction. For example, if the outer portion 113 is inclined and curved in an arc as described above, one or more anti-suction members 300 may extend along the inclination direction of the outer portion 113 (i.e., an oblique direction including components in the Z' and Y' directions) and curve in an arc (see Figures 1A to 2B), or they may not be curved and may extend linearly along the inclination direction of the outer portion 113. If the outer portion 113 is inclined as described above but not curved, one or more anti-suction members 300 extend linearly along the inclination direction of the outer portion 113 (not shown). If the outer portion 113 is not inclined and curved in an arc as described above, one or more anti-suction members 300 extend in the Z' direction and curve in an arc (not shown). If the outer portion 113 is not inclined and not curved, one or more anti-suction members 300 extend in the Z' direction. The bases of one or more anti-suction members 300 may be joined to the lower end of the outer portion 113, or they may be inserted into the bag portion 110 from between the outer portion 113 and the bottom portion 114 and fixed to the inner surface of the outer portion 113. 【0043】 (b) One or more anti-suction members 300 are flanges (not shown) extending from the outer end of the upper portion 111 or the bottom portion 114 of the bag portion 110 in a direction including a component in the Y' direction. The bases of one or more anti-suction members 300 may be joined to the outer end of the upper portion 111 or the bottom portion 114, or they may be inserted into the bag portion 110 from between the upper portion 111 and the outer portion 113 or between the bottom portion 114 and the outer portion 113 and fixed to the inner surface of the upper portion 111 or the bottom portion 114. 【0044】 (c) One or more anti-suction members 300 are flanges (not shown) extending from the upper part 111 or the bottom part 114 of the bag part 110 in a direction including a component in the X direction. The base of one or more anti-suction members 300 may be joined to the X-direction end of the upper part 111 or the bottom part 114, or they may be inserted into the bag part 110 from between the upper part 111 and the outer part 113 and fixed to the inner surface of the upper part 111, or inserted into the bag part 110 from between the bottom part 114 and the outer part 113 and fixed to the inner surface of the bottom part 114. If the bag portion 110 is provided with a pair of side portions 115, the bag portion 110 may be inserted into the bag portion 110 from between the upper portion 111 and the side portion 115 on the X-direction side and fixed to the inner surface of the upper portion 111, or it may be inserted into the bag portion 110 from between the bottom portion 114 and the side portion 115 on the X-direction side and fixed to the inner surface of the bottom portion 114. 【0045】 (d) One or more anti-suction members 300 are flanges (not shown) extending from the upper part 111 or the bottom part 114 of the bag part 110 in a direction including a component in the X' direction. The base of one or more anti-suction members 300 may be joined to the X' direction end of the upper part 111 or the bottom part 114, or they may be inserted into the bag part 110 from between the upper part 111 and the outer part 113 and fixed to the inner surface of the upper part 111 or the bottom part 114, or inserted into the bag part 110 from between the bottom part 114 and the outer part 113 and fixed to the inner surface of the bottom part 114. If the bag portion 110 is provided with a pair of side portions 115, the bag portion 110 may be inserted into the bag portion 110 from between the upper portion 111 and the side portion 115 on the X' direction and fixed to the inner surface of the upper portion 111, or it may be inserted into the bag portion 110 from between the bottom portion 114 and the side portion 115 on the X' direction and fixed to the inner surface of the bottom portion 114. 【0046】 (e) One or more anti-suction members 300 are beams extending from the housing 220 or bag portion 110 of at least one fan 200 (first fan 200a and / or second fan 200b) in a direction including a component in the Z' direction (not shown). 【0047】 (f) One or more anti-suction members 300 are hood-shaped covers (not shown) that are hemispherical, quarter-spherical, arc-shaped, or of other shapes, provided on the housing 220 or bag portion 110 of at least one fan 200 (first fan 200a and / or second fan 200b). If one or more anti-suction members 300 are provided on at least one fan 200, one or more anti-suction members 300 may also serve as an outer guard portion of at least one fan 200 (first fan 200a and / or second fan 200b). In this case, one or more anti-suction members 300 are provided with multiple holes. If one or more anti-suction members 300 are provided on the bag portion 110, one or more anti-suction members 300 cover at least one fan 200 (first fan 200a and / or second fan 200b) at least partially. If one or more of the anti-suction members 300 are hemispherical shell-shaped, then one or more of the anti-suction members 300 are provided with multiple holes. If one or more of the anti-suction members 300 are quarter-spherical shell-shaped or arc-shaped, then one or more of the anti-suction members 300 may or may not have multiple holes. 【0048】 The wearable blower D1 may further include at least one locking portion 400. The at least one locking portion 400 is one or more and is provided on at least one of the outer portion 113, upper portion 111, and bottom portion 114 of the bag portion 110. If the bag portion 110 is provided with a pair of side portions 115, the one or more locking portions 400 are provided on at least one of the outer portion 113, upper portion 111, bottom portion 114, and the pair of side portions 115. The one or more locking portions 400 are downward-facing U-shaped hooks or pins to which the lower end of the back of the jacket is hooked, but any object that can hook the jacket is acceptable. 【0049】 The mounted blower D1 may further include a reinforcing part (not shown). The reinforcing part reinforces the edge of at least one exhaust port 101. This allows the upper part 111 to be flexible, preventing at least one exhaust port 101 from being crushed and partially or completely blocked. The reinforcing part may be flexible or rigid. The reinforcing part is made of a resin plate, wire, or a fabric or high-density woven material similar to the upper part 111 of the bag part 110, etc. The resin plate may be made of, for example, polyvinyl chloride (PVC), polypropylene, polyethylene, polycarbonate, polyethylene terephthalate, ethylene vinyl acetate copolymer resin (EVA resin), or ABS resin. If the upper part 111 of any of the above embodiments is provided, the reinforcing part is fixed to any point on the inner surface of the upper part 111 of any of the above embodiments. For example, the reinforcing portion can be configured to be fixed to the edge of at least one exhaust port 101, or it can be configured to be fixed to the upper portion 111 of either of the above-described embodiments and to extend along the upper portion 111. 【0050】 The reinforcing portion can be configured to have at least one communication hole, the same number as the at least one exhaust port 101 that penetrates the reinforcing portion. In this case, the reinforcing portion may be fixed to the upper portion 111 such that one or more communication holes communicate with one or more exhaust ports 101. The communication holes are optional. The reinforcing portion itself can also be omitted. 【0051】 The above-described wearable blower D1 exhibits the following technical features and effects (1) to (7). 【0052】 (1) Technical features and effects The first fan 200a is attached to and supported by the first mounting hole 102a of the first support portion 114a. Because the first support portion 114a extends in an oblique direction including components in the X and Z' directions, the airflow direction Wa of at least a portion of the air blown by the first fan 200a supported by the first support portion 114a is directed toward the first portion 111a of the upper portion 111 of the bag portion 110. Therefore, by driving the first fan 200a, air can be blown to at least one first exhaust port 101a of the first portion 111a of the upper portion 111. Since the first part 111a of the upper part 111 is positioned near at least one of the first lateral part Ha and the first lateral part Fa of the waist H when worn, air discharged from at least one of the first exhaust port 101a of the first part 111a is blown from between at least one of the first lateral part Ha and the first lateral part Fa of the waist H and the back of the garment to at least one of the first lateral part Ha and the first lateral part Fa of the waist H. If the direction Wa of some of the air blown by the first fan 200a supported by the first support portion 114a (all the air being blown) is directed toward the first portion 111a of the upper portion 111 of the bag portion 110, and the direction Wa of another portion of the air blown is directed toward the X-direction side portion of the third portion 111c of the upper portion 111 of the bag portion 110, then the first fan 200a can blow air not only to at least one first exhaust port 101a of the first portion 111a of the upper portion 111, but also to at least one third exhaust port 101c of the third portion 111c. Since the third portion 111c is located near the central portion Hc of the waist H when worn, the air discharged from at least one third exhaust port 101c of the third portion 111c is blown toward the central portion Hc of the waist H from between the central portion Hc of the waist H and the back of the garment. 【0053】 (2) Technical features and effects When a second support portion 114b and a second mounting hole 102b are provided, the second fan 200b is attached to and supported by the second mounting hole 102b of the second support portion 114b. Because the second support portion 114b extends in an oblique direction including components in the X' and Z' directions, the airflow direction Wb of at least a portion of the air blown by the second fan 200b supported by the second support portion 114b is directed toward the second portion 111b of the upper portion 111 of the bag portion 110. Therefore, by driving the second fan 200b, air can be blown to at least one second exhaust port 101b of the second portion 111b of the upper portion 111. Since the second part 111b of the upper part 111 is positioned near at least one of the second lateral part Hb and second lateral abdomen Fb of the waist H when worn, air discharged from at least one of the second exhaust ports 101b of the second part 111b of the upper part 111 is blown from between at least one of the second lateral part Hb and second lateral abdomen Fb of the waist H and the back of the garment to at least one of the second lateral part Hb and second lateral abdomen Fb of the waist H. If the direction Wb of the airflow of a portion of the air blown by the second fan 200b supported by the second support portion 114b (all the air being blown) is directed toward the second portion 111b of the upper part 111 of the bag portion 110, and the direction Wb of the airflow of another portion of the air is directed toward the X' direction portion of the third portion 111c of the upper part 111 of the bag portion 110, then the second fan 200b can blow air not only to at least one second exhaust port 101b of the second portion 111b of the upper part 111, but also to at least one third exhaust port 101c of the third portion 111c. Since the third portion 111c is located near the central portion Hc of the waist H when worn, the air discharged from at least one third exhaust port 101c of the third portion 111c is blown toward the central portion Hc of the waist H from between the central portion Hc of the waist H and the back of the garment. 【0054】 (3) Technical features and effects Even when a third support, a third mounting hole, and a third fan are provided, the third fan can be driven to blow air into at least one third exhaust port 101c of the third part 111c. Furthermore, even when a portion of the airflow direction Wa of the air blown by the first fan 200a and the second fan 200b is not directed toward the third part 111c of the upper part 111 of the bag part 110 and the third support and third mounting hole are not provided, the first fan 200a and the second fan 200b can be driven to introduce air into the bag part 110, thereby allowing air to be discharged from at least one third exhaust port 101c of the third part 111c. Since the third part 111c is positioned near the central part Hc of the waist H when worn, the air discharged from at least one third exhaust port 101c of the third part 111c is blown from between the central part Hc of the waist H and the back of the garment toward the central part Hc of the waist H. 【0055】 (4) Technical features and effects When the first part 111a of the upper part 111 of the bag part 110 extends in an oblique direction including components in the X and Z directions when installed, and at least one first exhaust port 101a opens in an oblique direction including components in the X and Z directions, the air blown by the drive of the first fan 200a can be suitably discharged from at least one first exhaust port 101a of the first part 111a of the upper part 111. 【0056】 (5) Technical features and effects When the second part 111b of the upper part 111 of the bag part 110 is installed, it extends in an oblique direction including components in the X' and Z' directions, and at least one second exhaust port 101b opens in an oblique direction including components in the X' and Z directions, so that the air blown by the second fan 200b can be suitably discharged from at least one second exhaust port 101b of the second part 111b of the upper part 111. 【0057】 (6) Technical features and effects If at least one anti-suction member 300 is provided, when the device is attached, the at least one anti-suction member 300 will come into contact with the back of the user's jacket, making it difficult for the lower end of the back of the jacket to be positioned near the at least one fan 200 that is exposed from the bottom side 114 of the bag portion 110. Therefore, it is possible to prevent the back of the user's jacket from being attracted to the at least one fan 200 by the air intake from the at least one fan 200. 【0058】 (7) Technical features and effects If at least one locking portion 400 is provided, when the device is attached, at least one locking portion 400 is hooked onto the back of the user's jacket, so that the lower end of the back of the jacket is not positioned near at least one fan 200 exposed from the bottom side portion 114 of the bag portion 110. This prevents the back of the user's jacket from being attracted to at least one fan 200 by the air intake from at least one fan 200. 【0059】 Furthermore, the mountable blower D1 can be modified in the following way and as shown in Figure 3B. Figure 3B shows a second design modification example of the mountable blower D1 of Example 1. To distinguish this second design modification example from the mountable blower D1 of Example 1 and its design modification example described above, the reference numeral "D1'" is used. Note that the mountable blower D1' has the same configuration as the mountable blower D1 except for the configuration of the design modifications shown below. 【0060】 Although the upper part 111 of the bag portion 110 of the mounted blower D1' is assumed to have a first part 111a, a second part 111b, and a third part 111c, it is possible to have a configuration in which the inner part 112, rather than the upper part 111, has the first part 111a, the second part 111b, and the third part 111c (see Figure 3B). The first part 111a is the portion of the inner part 112 on the X-direction side (for example, the X-direction end of the inner part 112 (see Figure 3B) or its X'-direction side portion (not shown)). The second part 111b is the portion of the inner part 112 on the X'-direction side (for example, the X'-direction end of the inner part 112 (see Figure 3B) or its X-direction side portion (not shown)). The third part 111c is the intermediate portion of the inner part 112 between the first part 111a and the second part 111b. One or more first exhaust ports 101a provided in the first part 111a of the inner part 112 open in a direction that includes a component in the Y direction. If one or more second exhaust ports 101b are provided in the second part 111b of the inner part 112, one or more second exhaust ports 101b open in a direction that includes a component in the Y direction. If one or more third exhaust ports 101c are provided in the third part 111c of the inner part 112, one or more third exhaust ports 101c open in a direction that includes a component in the Y direction. 【0061】 Part 1 111a may extend in an oblique direction including components in the X and Y' directions (may be inclined downwards) when worn, but may not extend in such an oblique direction (may not be inclined). Part 2 111b may extend in an oblique direction including components in the X' and Y' directions (may be inclined downwards) when worn, but may not extend in such an oblique direction (may not be inclined). When Part 1 111a and Part 2 111b are inclined, when worn, the inner part 112 is configured such that Part 3 111c forms the upper side of a roughly trapezoid, Part 1 111a forms the first hypotenuse of the roughly trapezoid, and Part 2 111b forms the second hypotenuse of the roughly trapezoid. When Part 1 111a and Part 2 111b are not inclined, the inner part 112, Part 1 111a, Part 2 111b, and Part 3 111c, extend in the Z-Z' direction when worn. If the first section 111a is inclined, one or more first exhaust ports 101a open in an oblique direction including components in the Y and X directions. If the second section 111b is inclined and one or more second exhaust ports 101b are provided, one or more second exhaust ports 101b open in an oblique direction including components in the Y and X' directions. At least one second exhaust port 101b and / or at least one third exhaust port 101c are optional. 【0062】 The bottom portion 114 of the bag portion 110 of the wearable blower D1' does not have at least one support portion; rather, the outer portion 113 has at least one support portion. The at least one support portion is located on the Y' direction side with respect to the third portion 111c of the inner portion 112 (see Figure 3B). That is, the at least one support portion forms a part of the outer portion 113 that is located on the Y' direction side with respect to the third portion 111c. 【0063】 The first support portion 114a of the mounted blower D1' is a part located on the Y' direction side relative to the third portion 111c of the outer portion 113, and extends in an oblique direction including components in the X and Y directions when mounted (slopes downward). If the first portion 111a of the inner portion 112 is inclined, the inclination angle of the first support portion 114a and the inclination angle of the first portion 111a of the inner portion 112 may be approximately the same or different. That is, the inclination direction in which the first support portion 114a extends and the inclination direction in which the first portion 111a of the inner portion 112 extends may be the same or different. The first support portion 114a is provided with a first mounting hole 102a that penetrates the first support portion 114a in an oblique direction including components in the X and Y directions. The first fan 200a of the mounted blower D1' is attached to the first mounting hole 102a of the first support portion 114a, similar to the first fan 200a of the mounted blower D1. Because the first support portion 114a extends in an oblique direction including components in the X and Y' directions, the airflow direction Wa of at least some of the air blown by the first fan 200a supported by the first support portion 114a (i.e., all or some of the air blown by the first fan 200a) is directed toward the first portion 111a of the inner portion 112 of the bag portion 110. The airflow direction Wa of a portion of the air blown by the first fan 200a supported by the first support portion 114a (all the air being blown) may be directed toward the first portion 111a of the inner portion 112 of the bag portion 110, and the airflow direction Wa of another portion of the air may be directed toward the X-direction side portion of the third portion 111c of the inner portion 112 of the bag portion 110. 【0064】 If the mounted blower D1' is provided with a second support portion 114b, the second support portion 114b is a separate part of the outer portion 113 on the X' side relative to the first support portion 114a, and is located on the Y' side relative to the third portion 111c of the inner portion 112, and extends in an oblique direction including components in the X' and Y' directions when mounted (slopes downward). If the second portion 111b of the inner portion 112 is inclined, the inclination angle of the second support portion 114b and the inclination angle of the second portion 111b of the inner portion 112 may be approximately the same or different. That is, the inclination direction in which the second support portion 114b extends and the inclination direction in which the second portion 111b of the inner portion 112 extends may be the same or different. The second support portion 114b is provided with a second mounting hole 102b that penetrates the second support portion 114b in an oblique direction including components in the X' and Y directions. The second fan 200b of the mounted blower D1' is attached to the second mounting hole 102b of the second support portion 114b, similar to the second fan 200b of the mounted blower D1. Because the second support portion 114b extends in an oblique direction including components in the X' and Y' directions, the airflow direction Wb of at least some of the air blown by the second fan 200b supported by the second support portion 114b (i.e., all or some of the air blown by the second fan 200b) is directed toward the second portion 111b of the inner portion 112 of the bag portion 110. The direction Wb of some of the air blown by the second fan 200b supported by the second support portion 114b (all the air being blown) may be directed toward the second portion 111b of the inner portion 112 of the bag portion 110, and the direction Wb of another portion of the air blown may be directed toward the X' direction side portion of the third portion 111c of the inner portion 112 of the bag portion 110. 【0065】 If a first support portion 114a and a second support portion 114b are provided, the first support portion 114a and the second support portion 114b may be in a substantially V-shape that is convex in the Y direction (not shown). Alternatively, if a first support portion 114a and a second support portion 114b are provided, the outer portion 113 may further have an intermediate portion between the first support portion 114a and the second support portion 114b, where the intermediate portion forms the upper side of a substantially trapezoid, the first support portion 114a forms the first hypotenuse of the substantially trapezoid, and the second support portion 114b forms the second hypotenuse of the substantially trapezoid (not shown). If the outer portion 113 is inclined in an oblique direction including components in the Y' and Z' directions when installed, the first support portion 114a and the second support portion 114b are also inclined in an oblique direction including components in the Y' and Z' directions. 【0066】 If a third support portion is provided for the mounted blower D1', the third support portion is located in the intermediate portion between the first support portion 114a and the second support portion 114b of the outer portion 113, and is positioned on the Y' direction side with respect to the third portion 111c of the inner portion 112. The third fan of the mounted blower D1' is mounted to a third mounting hole provided in the third support portion, similar to the third fan of the mounted blower D1. The direction of airflow from the third fan supported by the third support portion is directed toward the third portion 111c of the inner portion 112 of the bag portion 110. Note that the second support portion 114b and the second fan 200b are optional. The third support portion and the third fan are optional. 【0067】 This type of wearable blower D1' also exhibits the same technical features and effects as the wearable blower D1(1)~(7) technical features and effects. [Examples] 【0068】 The following describes several embodiments of the present invention, including Embodiment 2 and its design modifications, of the wearable blower D2, with reference to Figure 4A. Figure 4A shows the wearable blower D2 of Embodiment 2, but the belt portions 121 and 122 of the wearable blower D2 are omitted from the illustration. Note that Figure 4A also shows the Z-Z' and X-X' directions. For the Y-Y' direction, please refer to Figure 2B. 【0069】 The mountable blower D2 has the same configuration as the mountable blower D1, except that at least one support portion 120 is located inside the bag portion 110 rather than on the bottom side portion 114 of the bag portion 110, and at least one air intake port 103 is provided on the bottom side portion 114 of the bag portion 110 instead of at least one support portion 120. The differences will be explained in detail below, and any part of the description of the mountable blower D2 that overlaps with that of the mountable blower D1 will be omitted. As mentioned above, at least one support portion of the mountable blower D2 is denoted by the reference numeral "120" to distinguish it from at least one support portion of the mountable blower D1. 【0070】 Although the bag portion 110 of the wearable blower D2 is shown as having the configuration described in (3) above, it is possible to have the same configuration as the bag portion 110 of the wearable blower D1, as described in (1), (2), or other design modification examples. 【0071】 At least one air intake 103 is provided on the bottom side portion 114 of the bag portion 110, penetrates the bottom side portion 114, and opens in a direction that includes a component in the Z' direction (see Figure 4A). At least one air intake 103 may be mesh-like or simply a through hole. If the bottom side portion 114 slopes downward from the lower end of the inner portion 112 to the lower end of the outer portion 113 when installed, at least one air intake 103 slopes downward diagonally along the bottom side portion 114, including components in the Y' and Z' directions when installed. If the bottom side portion 114 is approximately horizontal when installed, at least one air intake 103 is approximately horizontal when installed. The number of at least one air intake 103 may be one, the same number as the number of at least one fan 200, or a different number. One or more air intake ports 103 may be provided on the outer part 113 of the bag portion 110, rather than on the bottom side portion 114 of the bag portion 110 (not shown). 【0072】 At least one support portion 120 may be made of the above-mentioned fabric or high-density woven fabric, or it may be made of a resin plate. At least one support portion 120 may be suspended between the inner portion 112 and the outer portion 113 of the bag portion 110. If a pair of side portions 115 are provided, at least one support portion 120 may be suspended between the pair of side portions 115 of the bag portion 110, or it may be suspended between the inner portion 112 and the outer portion 113 of the bag portion 110. At least one support portion 120 is positioned in the bag portion 110 on the Z' side with respect to the third portion 111c of the upper portion 111 and on the Z side with respect to the bottom portion 114. At least one support portion 120 is located on the Z side with respect to one or more air intake ports 103. 【0073】 At least one support portion 120 includes a first support portion 121a. The first support portion 121a is a portion located on the Z' side with respect to the third portion 111c of at least one support portion 120, and extends in an oblique direction including components in the X and Z' directions when installed (it slopes downward). If the first portion 111a of the upper portion 111 is inclined, the inclination angle of the first support portion 121a and the inclination angle of the first portion 111a of the upper portion 111 may be approximately the same or different. That is, the inclination direction in which the first support portion 121a extends and the inclination direction in which the first portion 111a of the upper portion 111 extends may be the same or different. 【0074】 At least one support portion 120 may further include a second support portion 121b. The second support portion 121b is another part of at least one support portion 120 on the X' side relative to the first support portion 121a, located on the Z' side relative to the third portion 111c, and extends in an oblique direction including components in the X' and Z' directions when installed (sloping downwards). If the second portion 111b of the upper portion 111 is inclined, the inclination angle of the second support portion 121b and the inclination angle of the second portion 111b of the upper portion 111 may be approximately the same or different. That is, the inclination direction in which the second support portion 121b extends and the inclination direction in which the second portion 111b of the upper portion 111 extends may be the same or different. 【0075】 If a first support portion 121a and a second support portion 121b are provided, the first support portion 121a and the second support portion 121b may be in a substantially V-shape that is convex in the Z direction (see Figure 4A). Alternatively, if a first support portion 121a and a second support portion 121b are provided, at least one support portion 120 may further have an intermediate portion between the first support portion 121a and the second support portion 121b, where the intermediate portion forms the upper side of a substantially trapezoid, the first support portion 121a forms the first hypotenuse of the substantially trapezoid, and the second support portion 121b forms the second hypotenuse of the substantially trapezoid (not shown). 【0076】 At least one support portion 120 may further include a third support portion (not shown). The third support portion is an intermediate portion of at least one support portion 120 between the first support portion 121a and the second support portion 121b, and is located on the Z' side relative to the third portion 111c. The second support portion 121b and / or the third support portion are optional. 【0077】 At least one mounting hole 102' includes a first mounting hole 102a'. The first mounting hole 102a' is provided in the first support portion 121a and penetrates the first support portion 121a in an oblique direction including components in the Z and X directions. If a second support portion 121b is provided, at least one mounting hole 102' further includes a second mounting hole 102b'. The second mounting hole 102b' is provided in the second support portion 121b and penetrates the second support portion 121b in an oblique direction including components in the Z and X' directions. 【0078】 If a third support is provided, at least one mounting hole 102' further includes a third mounting hole (not shown). The third mounting hole is provided in the third support and penetrates the third support in a direction including a component in the Z direction. The second mounting hole 102b' is optional, along with the second support 121b. The third mounting hole is optional, along with the third support. 【0079】 At least one fan 200 of the wearable blower D2 has the same configuration as at least one fan 200 of the wearable blower D1. 【0080】 The first fan 200a of at least one fan 200 of the mounted blower D2 has the above configuration and, similar to the first fan 200a of at least one fan 200 of the mounted blower D1, is attached to and supported by the first mounting hole 102a' of the first support portion 121a. Because the first support portion 121a extends in an oblique direction including components in the X and Z' directions, the airflow direction Wa (see Figure 4A) of at least a portion of the air blown by the first fan 200a supported by the first support portion 121a (i.e., all or part of the air blown by the first fan 200a) is directed toward the first portion 111a of the upper portion 111 of the bag portion 110. The airflow direction Wa of a portion of the air blown by the first fan 200a supported by the first support portion 121a (all the air being blown) may be directed toward the first portion 111a of the upper portion 111 of the bag portion 110, and the airflow direction Wa of another portion of the air may be directed toward the X-direction side portion of the third portion 111c of the upper portion 111 of the bag portion 110. 【0081】 If the mounted blower D2 is provided with a second support portion 121b, a second mounting hole 102b', and a second fan 200b, the second fan 200b of the mounted blower D2 has the above configuration and is attached to and supported by the second mounting hole 102b of the second support portion 121b, similar to the second fan 200b of at least one fan 200 of the mounted blower D1. Because the second support portion 121b extends in an oblique direction including components in the X' and Z' directions, the airflow direction Wb (see Figure 4A) of at least some of the air blown by the second fan 200b supported by the second support portion 121b (i.e., all or some of the air blown by the second fan 200b) is directed toward the second portion 111b of the upper portion 111 of the bag portion 110. The airflow direction Wb of a portion of the air blown by the second fan 200b supported by the second support portion 121b (all the air being blown) may be directed toward the second portion 111b of the upper portion 111 of the bag portion 110, and the airflow direction Wb of another portion of the air may be directed toward the portion of the third portion 111c of the upper portion 111 of the bag portion 110 that is on the X' side. 【0082】 If a third support portion and a third mounting hole are provided, at least one fan 200 further includes a third fan (not shown). The third fan has the configuration described above and is mounted and supported in the third mounting hole of the third support portion as described above. The direction of airflow from the third fan supported by the third support portion is directed toward the third portion 111c of the upper portion 111 of the bag portion 110. 【0083】 At least one fan 200 motor is driven, causing the rotating blades 210 to rotate, which in turn draws air into the bag section 110 from at least one intake port 103 and expels it from at least one exhaust port 101. 【0084】 The wearable blower D2 may further include at least one battery (not shown), or it may use an external battery. The wearable blower D2 may further include at least one anti-suction member 300 and / or at least one locking part 400, or it may not. 【0085】 The wearable blower D2 may further include at least one ventilation section 500. The at least one ventilation section 500 is one or more and is made of a resin fiber structure composed of materials such as Breathair® manufactured by Toyobo Co., Ltd. or Saranlock® manufactured by Asahi Kasei Corporation, or a foam material (sponge) which is a continuous foam. One or more ventilation passages 510 are formed inside one or more ventilation sections 500. One or more ventilation sections 500 are interposed between the bottom side portion 114 of the bag portion 110 and at least one fan 200. One or more ventilation passages 510 of one or more ventilation sections 500 are ventilatingly connected to at least one intake port 103 of the bottom side portion 114 and at least one fan 200. In Figure 4A, there is at least one ventilation section 500, which is interposed between the bottom side 114 of the bag section 110, the first and second fans 200a and 200b, and at least one support section 120. Multiple ventilation passages 510 are provided within this ventilation section 500, and the first and second fans 200a and 200b and at least one intake port 103 are connected in a ventilatory manner by these multiple ventilation passages 510. 【0086】 At least one fan 200 is driven by a motor, causing its rotating blades 210 to rotate, which causes air to reach the at least one fan 200 from at least one intake port 103, through one or more ventilation passages 510 of one or more ventilation sections 500, and be discharged from at least one exhaust port 101. Note that at least one ventilation section 500 is optional. 【0087】 The above-described wearable blower D2 exhibits the same technical features and effects as the wearable blower D1(1)~(7). 【0088】 Furthermore, the mountable blower D2 can be modified in the following way and as shown in Figure 4B. Figure 4B shows the first design modification example of the mountable blower D2 of Embodiment 2. To distinguish this first design modification example of the mountable blower from the mountable blower D2 of Embodiment 2 and its design modification example described above, it is denoted as "D2'". The mountable blower D2' has the same configuration as the mountable blower D2 except for the configuration of the design modification shown below. 【0089】 Instead of the upper part 111 of the bag portion 110 of the wearable blower D2' having a first part 111a, a second part 111b, and a third part 111c, it is possible to have an inner part 112 having a first part 111a, a second part 111b, and a third part 111c. The first part 111a, a second part 111b, and a third part 111c of the inner part 112 of the wearable blower D2' can be configured in the same way as the first part 111a, a second part 111b, and a third part 111c of the inner part 112 of the wearable blower D1'. 【0090】 One or more air intake ports 103 of the mounted blower D2' are located on the outer portion 113 of the bag portion 110, not the bottom portion 114, and penetrate the outer portion 113 and open in a direction that includes a component in the Y' direction (see Figure 4B). If the outer portion 113 is inclined in an oblique direction including components in the Y' and Z' directions from the outer end of the upper portion 111 to the outer end of the bottom portion 114 when mounted, one or more air intake ports 103 are inclined downward in an oblique direction including components in the Y' and Z' directions along the outer portion 113 when mounted. If the outer portion 113 extends in the Z-Z' direction when mounted, one or more air intake ports 103 extend in the Z-Z' direction when mounted. Note that one or more air intake ports 103 may be located on the bottom portion 114 of the bag portion 110 instead of the outer portion 113 of the bag portion 110 (not shown). 【0091】 At least one support portion 120 of the mounted blower D2' is suspended from the upper portion 111 and the bottom portion 114 of the bag portion 110, and is positioned within the bag portion 110 on the Y' side relative to the third portion 111c of the inner portion 112 and on the Y side relative to the outer portion 113. If a pair of side portions 115 are provided, at least one support portion 120 is suspended from the pair of side portions 115 of the bag portion 110 or from the upper portion 111 and the bottom portion 114 of the bag portion 110, and is positioned within the bag portion 110 on the Y' side relative to the third portion 111c of the inner portion 112 and on the Y side relative to the outer portion 113. At least one support portion 120 is located on the Y side relative to one or more intake ports 103. 【0092】 The first support portion 121a of at least one support portion 120 of the mounted blower D2' is a portion located on the Y' side relative to the third portion 111c of at least one support portion 120, and extends in an oblique direction including components in the X and Y directions when mounted (slopes downward). When the first portion 111a of the inner portion 112 is inclined, the inclination angle of the first support portion 121a and the inclination angle of the first portion 111a of the inner portion 112 may be approximately the same or different. That is, the inclination direction in which the first support portion 121a extends and the inclination direction in which the first portion 111a of the inner portion 112 extends may be the same or different. The first support portion 121a is provided with a first mounting hole 102a' that penetrates the first support portion 121a in an oblique direction including components in the X and Y directions. The first fan 200a of the mounted blower D2' is attached to the first mounting hole 102a' of the first support portion 121a, similar to the first fan 200a of the mounted blower D2. Because the first support portion 121a extends in an oblique direction including components in the X and Y' directions, the airflow direction Wa of at least some of the air blown by the first fan 200a supported by the first support portion 121a (i.e., all or some of the air blown by the first fan 200a) is directed toward the first portion 111a of the inner portion 112 of the bag portion 110. The airflow direction Wa of a portion of the air blown by the first fan 200a supported by the first support portion 121a (all the air being blown) may be directed toward the first portion 111a of the inner portion 112 of the bag portion 110, and the airflow direction Wa of another portion of the air may be directed toward the X-direction side portion of the third portion 111c of the inner portion 112 of the bag portion 110. 【0093】 If a second support portion 121b is provided for at least one support portion 120 of the mounted blower D2', the second support portion 121b is a separate part of the at least one support portion 120 on the X' side relative to the first support portion 121a, is located on the Y' side relative to the third portion 111c of the inner portion 112, and extends in an oblique direction including components in the X' and Y' directions when mounted (slopes downward). If the second portion 111b of the inner portion 112 is inclined, the inclination angle of the second support portion 121b and the inclination angle of the second portion 111b of the inner portion 112 may be approximately the same or different. That is, the inclination direction in which the second support portion 121b extends and the inclination direction in which the second portion 111b of the inner portion 112 extends may be the same or different. The second support portion 121b is provided with a second mounting hole 102b' that penetrates the second support portion 121b in an oblique direction including components in the X' and Y directions. The second fan 200b of the mounted blower D2' is attached to the second mounting hole 102b' of the second support portion 121b, similar to the second fan 200b of the mounted blower D2. Because the second support portion 121b extends in an oblique direction including components in the X' and Y' directions, the airflow direction Wb of at least some of the air blown by the second fan 200b supported by the second support portion 121b (i.e., all or some of the air blown by the second fan 200b) is directed toward the second portion 111b of the inner portion 112 of the bag portion 110. The direction Wb of some of the air blown by the second fan 200b supported by the second support portion 121b (all the air being blown) may be directed toward the second portion 111b of the inner portion 112 of the bag portion 110, and the direction Wb of another portion of the air blown may be directed toward the portion of the third portion 111c of the inner portion 112 of the bag portion 110 that is on the X' side. 【0094】 If a first support portion 121a and a second support portion 121b are provided, the first support portion 121a and the second support portion 121b may be in a substantially V-shape that is convex in the Y direction (not shown). Alternatively, if a first support portion 121a and a second support portion 121b are provided, at least one support portion 120 may further have an intermediate portion between the first support portion 121a and the second support portion 121b, where the intermediate portion forms the upper side of a substantially trapezoid, the first support portion 121a forms the first hypotenuse of the substantially trapezoid, and the second support portion 121b forms the second hypotenuse of the substantially trapezoid (not shown). 【0095】 If at least one support portion 120 third support portion is provided, the third support portion is an intermediate portion between the first support portion 121a and the second support portion 121b of at least one support portion 120, and is located on the Y' direction side with respect to the third portion 111c of the inner portion 112. The third fan of the mounted blower D2' is attached to the third mounting hole provided in the third support portion, similar to the third fan of the mounted blower D2. The direction of airflow from the third fan supported by the third support portion is directed toward the third portion 111c of the inner portion 112 of the bag portion 110. Note that the second support portion 114b and the second fan 200b are optional. The third support portion and the third fan are optional. 【0096】 If one or more ventilation sections 500 are provided, the configuration is as described above, except that one or more ventilation sections 500 are interposed between the outer part 113 of the bag section 110 and at least one fan 200. 【0097】 This type of wearable blower D2' also exhibits the same technical features and effects as the wearable blower D1(1)~(7) in terms of technical features and effects. [Examples] 【0098】 The following description will explain the wearable blower D3 according to Embodiment 3 of the present invention, with reference to Figures 5A to 5H. Figures 5A to 5H show the wearable blower D3 of Embodiment 3. 【0099】 The wearable blower D3 has the same configuration as the wearable blower D1, except that the bag portion 110 has the configuration described in (1) above, but at least one support portion is not provided on the bottom portion 114 of the bag portion 110, and instead one mounting hole 102 is provided on the bottom portion 114, and one fan 200 is attached to the mounting hole 102. Therefore, the description of the wearable blower D3 that overlaps with that of the wearable blower D1 will be omitted. [Examples] 【0100】 The following describes several embodiments of the present invention, including Embodiment 4 and its design modifications, of the wearable blower D4, with reference to Figures 6A to 6C. Figure 6A shows the wearable blower D4 of Embodiment 4. Figure 6B shows the first design modification of the wearable blower D4 of Embodiment 4.

In Figure 6A, the belt sections 121 and 122 are partially omitted, and in Figures 6B and 6C, the belt sections 121 and 122 are omitted from the illustration. Figure 6A shows the Z-Z' direction, the X-X' direction, and the Y-Y' direction. Figures 6B and 6C show the Z-Z' direction and the X-X' direction. 【0101】 The mounted fan D4 has the same configuration as the mounted fan D1, except that (a) the bag section 110 has the configuration described in (3) above, (b) the bag section 110 is provided with first and second support sections 130a and 130b instead of at least one support section, (c) the pair of side sections (first and second side sections 115a and 115b) of the bag section 110 are provided with first and second air intake ports 103a and 103b, (d) the configuration of the first and second fans 200a and 200b, and (e) the bag section 110 or the first and second fans 200a and 200b are provided with first and second anti-suction members 300a and 300b. The differences will be explained in detail below, and the description of the mounted fan D4 that overlaps with that of the mounted fan D1 will be omitted. 【0102】 The bag portion 110 of the mounted blower D4 has the configuration described in (3) above, but its bottom portion 114 does not have at least one support portion as described above (see Figures 6A to 6C). The first portion 111a and / or the second portion 111b of the upper portion 111 of the bag portion 110 may or may not be inclined (not shown) (see Figures 6A to 6C). 【0103】 A first exhaust port 101a may be provided in the first part 111a of the upper part 111, or a first exhaust port 101a may be provided in both the first part 111a and the inner part 112 of the upper part 111.

The first air intake port 103a opens in the X direction, while the second air intake port 103b opens in the X' direction. The first and second air intake ports 103a and 103b may be mesh-like (see Figure 6A) or simple through holes (see Figures 6B and 6C). There may be multiple first and second air intake ports 103a and 103b. 【0106】 The first support portion 130a is provided at the X-direction end of the bag portion 110 and supports the first fan 200a at the X-direction end of the bag portion 110. The first support portion 130a can be, for example, provided at the X-direction end of the bag portion 110 so as to be openable and closable and can be a partition that faces the first side portion 115a with a gap in between. The first fan 200a is supported between the first support portion 130a and the first side portion 115a. Alternatively, the first support portion 130a is, for example, a belt provided at the X-direction end of the bag portion 110 and fixed to the first fan 200a. The second support portion 130b is provided at the X'-direction end of the bag portion 110 and supports the second fan 200b at the X'-direction end of the bag portion 110. The second support portion 130b can be, for example, provided at the X'-side end of the bag portion 110 so as to be openable and closable, and can be a partition that faces the second side portion 115b with a gap between them. The second fan 200b is supported between the second support portion 130b and the second side portion 115b. Alternatively, the second support portion 130b can be, for example, a belt provided at the X-side end of the bag portion 110 and fixed to the second fan 200b. 【0107】 The first fan 200a of the mounted blower D4 is a sirocco fan and has an intake section 201a facing the first intake port 103a and an exhaust section 202a facing the first exhaust port 101a on the upper part 111 of the bag section 110.

When the first and second fans 200a and 200b are driven, air is drawn in from the intake sections 201a and 201b of the first and second fans 200a and 200b, discharged from the exhaust sections 202a and 202b, and blown to the first and second exhaust ports 101a and 101b. 【0108】 The wearable blower D4 may also be equipped with at least one additional battery (not shown), or it may use an external battery. 【0109】 The first and second anti-suction members 300a and 300b of the wearable blower D4 are provided protruding from the bag portion 110 or the first and second fans 200a and 200b, and are designed to prevent a person's upper garment from being attracted to the first and second fans 200a and 200b by the air intake from the first and second fans 200a and 200b. The first and second anti-suction members 300a and 300b of the wearable blower D4 have, for example, at least one of the following configurations (g) to (m). 【0110】 (g) The first and second anti-suction members 300a and 300b are flanges extending from the X-direction end, the X'-direction end, or the first and second side portions 115a and 115b of the upper portion 111 of the bag portion 110 in directions including the X and X' directions, and are located on the Z-direction side with respect to the first and second intake ports 103a and 103b (see Figure 6A). The base of the first anti-suction member 300a may be inserted into the bag portion 110 from between the upper portion 111 and the first side portion 115a and fixed to the inner surface of the first portion 111a or the first side portion 115a of the upper portion 111 (see Figure 6A). Alternatively, the first anti-suction member 300a may be joined to the X-direction end of the upper portion 111 or the first side portion 115a (not shown). The base of the second anti-suction member 300b may be inserted into the bag portion 110 from between the upper portion 111 and the second side portion 115b and fixed to the inner surface of the second portion 111b or the second side portion 115b of the upper portion 111 (see Figure 6A). Alternatively, the second anti-suction member 300a may be joined to the X'-direction end of the upper portion 111 or to the second side portion 115b (not shown). In addition, if the bases of the first and second anti-suction members 300a and 300b are fixed to the inner surfaces of the first and second portions 111a and 111b of the upper portion 111 of the bag portion 110, the bases of the first and second anti-suction members 300a and 300b may also serve as reinforcing parts that reinforce the edges of the first and second exhaust ports 101a and 101b of the first and second portions 111a and 111b. The bases of the first and second anti-suction members 300a and 300b may be provided with communication holes that communicate with the first and second exhaust ports 101a and 101b. The bases of the first and second anti-suction members 300a and 300b do not necessarily have to also serve as reinforcing parts. 【0111】 (h) The first and second anti-suction members 300a and 300b are hood-shaped covers in the shape of a quarter spherical shell, arc, or other shape, extending from the X-direction end, the X'-direction end, or the first and second side portions 115a and 115b of the upper portion 111 of the bag portion 110 in directions including the X and X' directions, and are located on the X-direction side and X'-direction side with respect to the first and second air intake ports 103a and 103b, respectively, and partially cover the first and second air intake ports 103a and 103b (see Figure 6B). The first and second anti-suction members 300a and 300b may or may not have a plurality of holes. The base of the first anti-suction member 300a may be inserted into the bag portion 110 from between the upper portion 111 and the first side portion 115a and fixed to the inner surface of the first portion 111a or the first side portion 115a of the upper portion 111 (see Figure 6A). Alternatively, the first anti-suction member 300a may be joined to the X-direction end of the upper portion 111 or to the first side portion 115a (not shown). The base of the second anti-suction member 300b may be inserted into the bag portion 110 from between the upper portion 111 and the second side portion 115b and fixed to the inner surface of the second portion 111b or the second side portion 115b of the upper portion 111 (see Figure 6A). Alternatively, the second anti-suction member 300a may be joined to the X'-direction end of the upper portion 111 or to the second side portion 115b (not shown). If the bases of the first and second anti-suction members 300a and 300b are fixed to the inner surfaces of the first and second portions 111a and 111b of the upper portion 111 of the bag portion 110, the bases of the first and second anti-suction members 300a and 300b may also serve as reinforcing portions that reinforce the edges of the first and second exhaust ports 101a and 101b of the first and second portions 111a and 111b. Communication holes communicating with the first and second exhaust ports 101a and 101b may be provided in the bases of the first and second anti-suction members 300a and 300b. Furthermore, the bases of the first and second anti-suction members 300a and 300b do not necessarily have to also serve as reinforcing parts. 【0112】 (i) The first and second anti-suction members 300a and 300b are hemispherical shell-shaped covers fixed to the first and second side portions 115a and 115b of the bag portion 110, and cover the first and second air intake ports 103a and 103b completely (see Figure 6B). The first and second anti-suction members 300a and 300b are provided with a plurality of holes. 【0113】 (j) The first and second anti-suction members 300a and 300b are quarter-spherical shell-shaped, arc-shaped or other shaped hood-like visors or flanges that extend from the first and second fans 200a and 200b in directions including the X and X' directions, and protrude from the first and second intake ports 103a and 103b in the X and X' directions (not shown). The visors are located on the X and X' sides relative to the intake portions 201a and 201b of the first and second fans 200a and 200b, partially covering the intake portions 201a and 201b of the first and second fans 200a and 200b and opening in the Z' direction. The flanges are located on the Z side relative to the intake portions 201a and 201b of the first and second fans 200a and 200b. 【0114】 (k) The first and second anti-suction members 300a and 300b are hemispherical shell-shaped covers provided on the first and second fans 200a and 200b, and protrude from the first and second air intake ports 103a and 103b in the X and X' directions, respectively (not shown). The first and second anti-suction members 300a and 300b are provided with a plurality of holes. These plurality of holes also serve as the air intake portions 201a and 201b of the first and second fans 200a and 200b. 【0115】 (l) The first and second anti-suction members 300a and 300b have a plurality of beams (not shown) extending from the X-direction end and X'-direction end of the upper part 111 of the bag portion 110 or from the first and second side portions 115a and 115b in directions including components in the X and X' directions. When the plurality of beams of the first and second anti-suction members 300a and 300b extend from the X-direction end and X'-direction end of the upper part 111 of the bag portion 110, all beams of the first and second anti-suction members 300a and 300b are located on the Z-direction side with respect to the first and second intake ports 103a and 103b. If multiple beams of the first and second anti-suction members 300a and 300b extend from the first and second side portions 115a and 115b, all beams of the first and second anti-suction members 300a and 300b may be located on the Z-direction side with respect to the first and second air intake ports 103a and 103b, or at least one of all beams of the first and second anti-suction members 300a and 300b may be located on the Z-direction side with respect to the first and second air intake ports 103a and 103b, while the other beams may be located on at least one of the Y-direction side, Y'-direction side, and Z'-direction side of the first and second air intake ports 103a and 103b, respectively. 【0116】 (m) The first and second anti-suction members 300a and 300b extend from the first and second fans 200a and 200b in directions including the X and X' directions, and have multiple beams protruding from the first and second intake ports 103a and 103b in the X and X' directions (not shown). All beams of the first and second anti-suction members 300a and 300b may be located on the Z-direction side with respect to the intake portions 201a and 201b of the first and second fans 200a and 200b, or at least one of all beams of the first and second anti-suction members 300a and 300b may be located on the Z-direction side with respect to the intake portions 201a and 201b of the first and second fans 200a and 200b, while the other beams may be located on at least one of the Y-direction side, Y'-direction side, and Z'-direction side of the intake portions 201a and 201b of the first and second fans 200a and 200b. 【0117】 Furthermore, the first and second anti-suction members 300a and 300b may be present in their entirety. 【0118】 Furthermore, the first and second fans 200a and 200b of the mounted blower D4 can be configured similarly to the first and second fans 200a and 200b of the mounted blower D1, rather than being sirocco fans. In this case, the first and second side portions 115a and 115b are provided with first and second mounting holes (not shown) instead of first and second intake ports 103a and 103b, and the first and second fans 200a and 200b of the mounted blower D4 are mounted to the first and second mounting holes in the same way as the first and second fans 200a and 200b of the mounted blower D1. In this case, the airflow direction of the first and second fans 200a and 200b of the mounted blower D4 is not directed toward the first and second exhaust ports 101a and 101b, but when the first and second fans 200a and 200b of the mounted blower D4 are driven, the air introduced into the bag section 110 is discharged from the first and second exhaust ports 101a and 101b. In this case, the intake section of the first and second fans 200a and 200b of the mounted blower D4 is the outer guard section, and the exhaust section of the first and second fans 200a and 200b of the mounted blower D4 is the inner guard section. 【0119】 The mounted blower D2 may or may not further include at least one locking part 400. 【0120】 When using the above-described mountable blower D4, the following technical features and effects (1) to (3) are achieved. 【0121】 (1) Technical features and effects When attached, the first anti-suction member 300a comes into contact with the back of the user's jacket, making it difficult for the lower end of the back of the jacket to be positioned near the first air intake port 103a of the first side portion 115a of the bag portion 110, the air intake portion 101a of the first fan 200a, or the first fan 200a exposed from the first mounting hole. Therefore, it is possible to prevent the back of the user's jacket from being attracted to the first air intake port 103a of the first side portion 115a of the bag portion 110, the air intake portion 101a of the first fan 200a, or the first fan 200a exposed from the first mounting hole by the air intake from the first fan 200a. 【0122】 (2) Technical features and effects The second anti-suction member 300b contacts the back of the user's jacket, making it difficult for the lower end of the back of the jacket to be positioned near the second air intake port 103b of the second side portion 115b of the bag portion 110, the air intake portion 101b of the second fan 200b, or the second fan 200b exposed from the first mounting hole. Therefore, it is possible to prevent the back of the user's jacket from being attracted to the second air intake port 103b of the second side portion 115b of the bag portion 110, the air intake portion 101b of the second fan 200b, or the second fan 200b exposed from the second mounting hole by the air intake from the second fan 200b. 【0123】 (3) Technical features and effects If at least one locking portion 400 is provided, when the bag is attached, at least one locking portion 400 is hooked onto the back of the wearer's jacket, so that the lower end of the back of the jacket is not positioned near the first air intake 103a of the first side portion 115a of the bag portion 110, the air intake portion 101a of the first fan 200a, or the first fan 200a exposed from the first mounting hole, and / or near the second air intake 103b of the second side portion 115b of the bag portion 110, the air intake portion 101b of the second fan 200b, or the second fan 200b exposed from the first mounting hole. Therefore, the intake by the first fan 200a prevents the back of the user's upper garment from being attracted to the first intake port 103a of the first side portion 115a of the bag portion 110, the intake portion 101a of the first fan 200a, or the first fan 200a exposed from the first mounting hole, and / or, the intake by the second fan 200b prevents the back of the user's upper garment from being attracted to the second intake port 103b of the second side portion 115b of the bag portion 110, the intake portion 101b of the second fan 200b, or the second fan 200b exposed from the second mounting hole. [Examples] 【0124】 The following describes several embodiments of the present invention, including Embodiment 5 and its design modifications, of the wearable blower D5, with reference to Figures 7A and 7B. Figures 7A and 7B show the wearable blower D5 of Embodiment 5. In Figures 7A and 7B, the belt sections 121 and 122 are omitted from the illustration.

At least one exhaust port 101 is provided on the upper portion 111 of the bag portion 110 and is located on the Z side relative to the exhaust portion 202 of at least one fan 200. The at least one exhaust port 101 may be one, or there may be multiple ports corresponding to the number of at least one fan 200, or there may be multiple ports for each fan 200. 【0132】 The wearable fan D5 may further include at least one battery (not shown), or it may use an external battery. If a pocket 112a is provided in the inner part 112, at least one battery may be housed in the pocket 112a of the inner part 112. Regardless of whether a pocket 112a is provided in the inner part 112, at least one battery may be housed in the bag part 110. Note that items other than batteries (e.g., ice packs) may be housed in the pocket 112a. 【0133】 At least one anti-suction member 300 is provided so as to protrude in the Y' direction from the outer part 113 of the bag portion 110 or from at least one fan 200, and is configured to prevent a person's upper garment from being attracted to at least one of the two fans 200 by the intake air from at least one fan 200. At least one anti-suction member 300 of the mounted blower D5 has, for example, at least one of the following configurations (n) to (t). 【0134】 (n) At least one anti-suction member 300 is a quarter-spherical shell-shaped, arc-shaped, or other hood-shaped cover extending from the Y'-direction end of the outer portion 113 or the upper portion 111 of the bag portion 110 in a direction including the Y' direction, and is located on the Y' direction side with respect to at least one air intake 103 and partially covers at least one air intake 103 (see Figures 7A and 7B). At least one anti-suction member 300 is open in the Z' direction. The base of at least one anti-suction member 300 may be inserted into the bag portion 110 from between the upper portion 111 and the outer portion 113 and fixed to the inner surface of the upper portion 111 or the outer portion 113. Alternatively, at least one anti-suction member 300 may be joined to the Y'-direction end of the upper portion 111 or to the outer portion 113. At least one anti-suction member 300 may or may not have multiple holes. If the base of at least one anti-suction member 300 is fixed to the inner surface of the upper part 111 of the bag part 110, the base of at least one anti-suction member 300 may also serve as a reinforcing part that reinforces the edge of at least one exhaust port 101 of the upper part 111. The base of at least one anti-suction member 300 may have a communication hole with at least one exhaust port 101.

In this case, the outer part 113 may have at least one mounting hole (not shown) instead of at least one intake port 103, and at least one fan 200 of the mounted blower D5 may be mounted in at least one mounting hole in the same way as at least one fan 200 of the mounted blower D1. In this case, the airflow direction of at least one fan 200 of the mounted blower D5 is not directed toward at least one exhaust port 101, but when at least one fan 200 of the mounted blower D5 is driven, the air introduced into the bag part 110 will be discharged from at least one exhaust port 101. In this case, the intake part of at least one fan 200 of the mounted blower D5 is the outer guard part, and the exhaust part of at least one fan 200 of the mounted blower D5 is the inner guard part. 【0142】 The mounted blower D2 may or may not further include at least one locking part 400. 【0143】 When using the above-described wearable blower D5, the following technical features and effects are achieved: (1) to (2). 【0144】 (1) Technical features and effects When attached, at least one anti-suction member 300 contacts the back of the user's upper garment, making it difficult for the lower end of the back of the upper garment to be positioned near at least one air intake 103 on the outer part 113 of the bag part 110, the air intake portion 101 of at least one fan 200, or at least one fan 200 exposed from at least one mounting hole. Therefore, it is possible to prevent the back of the user's upper garment from being attracted to at least one air intake 103 on the outer part 113 of the bag part 110, the air intake portion 101 of at least one fan 200, or at least one fan 200 exposed from at least one mounting hole by the air intake from at least one fan 200. 【0145】 (2) Technical features and effects If at least one locking portion 400 is provided, when the bag is attached, at least one locking portion 400 is hooked onto the back of the user's jacket, so that the lower end of the back of the jacket is not positioned near at least one air intake 103 on the outer portion 113 of the bag portion 110, at least one air intake portion 101 of the fan 200, or at least one fan 200 exposed from at least one mounting hole. Therefore, it is possible to prevent the back of the user's jacket from being attracted to at least one air intake 103 on the outer portion 113 of the bag portion 110, at least one air intake portion 101 of the fan 200, or at least one fan 200 exposed from at least one mounting hole by the air intake from at least one fan 200. 【0146】 (3) Technical features and effects At least one fan 200 (sirocco fan) is positioned such that its intake section 201 faces in the Y' direction and its exhaust section 202 faces in the Z direction. In other words, at least one fan 200 is positioned within the bag section 110 such that its thickness is minimized in the Y-Y' direction. Therefore, the bag section 110 of the mountable blower D5 can be made thinner in the Y-Y' direction.
