[0032] The following is based on Figure 1 to Figure 6 An embodiment in which the present invention is applied to clothing with a fan will be described. However, the technical scope of the present invention is not limited to the illustrated examples, and various modifications can be made to the embodiments described below without departing from the gist of the present invention.

[0033] In addition, the following description is based on the state in which the wearer wears the fan-equipped garment 100, and the front direction of the wearer is defined as front, the back direction of the wearer is defined as back, the upper direction of the wearer is defined as upper, the lower direction of the wearer is defined as lower, the right hand direction of the wearer is defined as right, the left hand direction of the wearer is defined as left, the axis along the front-to-back direction is defined as X-axis, the axis along the left-to-right direction is defined as Y-axis, and the axis along the up-down direction is defined as Z-axis for explanation.

[0034] In addition, when the opening and closing unit 11 of the clothing body 1 is opened, Figure 1 As shown, the direction in which the inner surface side of the garment body 1 (the side facing the wearer's body when worn) faces is defined as the front, and the opposite direction is defined as the back for description. In addition, when only the air supply device 2 is described, the direction is also defined based on the state of being installed on the garment 100 with a fan.

[0035] [Structure of 1 embodiment]

[0036] like Figure 1 As shown, the fan-equipped clothing 100 involved in the embodiment comprises a clothing body 1, an air supply device 2 for introducing air into the clothing body 1 (into the space between the clothing body 1 and the body of the wearer), a power supply device 3 for supplying voltage to the air supply device 2, and a power cable 4 connecting the power supply device 3 and the air supply device 2. After the air introduced into the clothing body 1 by the air supply device 2 flows along the body of the wearer or the surface of the underwear worn on the inside of the clothing body 1, it is discharged from the air discharge portion 14 formed on the collar and sleeves of the clothing body 1, thereby evaporating the sweat emitted from the body and cooling the body by utilizing the heat of vaporization during evaporation.

[0037] [(1) Clothing body]

[0038] The clothing body 1 is the clothing part of the clothing 100 with a fan except the air supply device 2, the power supply device 3 and the power cable 4. Figure 1 and Figure 2 As shown, it is formed in the shape of a jacket-like top that covers the torso and arms of the wearer.

[0039] The shape of the garment body 1 is not limited to such a shape as long as it covers at least a part of the wearer's body. For example, it may be formed into a vest type that covers only the torso of the wearer.

[0040] In addition, the surface facing the wearer when the garment body 1 is worn is referred to as the inner surface side, and the opposite surface facing the external space when the garment body 1 is worn is referred to as the outer surface side.

[0041] like Figure 1 As shown, the clothing body 1 has an opening and closing unit 11 on the front body, and the opening and closing unit 11 is a segmented part that can be opened and closed freely by a zipper or the like. Figure 1 and Figure 2 As shown, the clothing body 1 has an air leakage prevention unit 12, which is formed by having a stretchable component such as a rubber rope at the hem so as to surround the wearer's body, and is used to prevent the air in the clothing body 1 from leaking to the outside from the hem of the clothing body 1.

[0042] like Figure 1 and Figure 2 As shown, an air supply device mounting hole 13 is formed at a position corresponding to the left and right sides of the wearer's waist on the back of the clothing main body 1. The air supply device mounting hole 13 is a circular hole portion that connects the space inside the clothing main body 1 with the space outside the clothing main body 1 when the clothing 100 with a fan is worn.

[0043] The air supply device mounting hole 13 is formed to have a diameter that is substantially the same as the diameter of the cylindrical portion 2412 of the outer shell 241 of the shell 24 of the air supply device 2 described later, and the air supply device 2 is mounted on the clothing main body 1 in such a manner that the cylindrical portion 2412 is inserted through the air supply device mounting hole 13, thereby enabling external air to be introduced into the space within the clothing main body 1 through the air supply device mounting hole 13.

[0044] like Figure 1 and Figure 2 As shown, an air exhaust portion 14 is formed in an opening between the wearer's neck and the end of the collar portion of the clothing main body 1, and in an opening between the wearer's arm and the end of the sleeve portion of the clothing main body 1. The air exhaust portion 14 is an opening for exhausting the air introduced into the clothing main body 1 by the air supply device 2 after it flows along the wearer's body or underwear.

[0045] like Figure 1As shown, a power supply device holding unit 15 and a cable holding unit 16 are provided on the inner surface side of the clothing main body 1. The power supply device holding unit 15 is used to hold the power supply device 3 at a position where it can be connected to the air supply device 2 via the power cable 4, and is formed into a bag shape that can accommodate the power supply device 3. The cable holding unit 16 is used to hold the power cable 4 on the inner surface side of the clothing main body 1, and is formed into a ring shape with an opening portion for the power cable 4 to be inserted.

[0046] [(2) Air supply device]

[0047] The air supply device 2 is a device for introducing air into the space between the clothing body 1 and the wearer's body through the air supply device mounting hole 13. Figure 1 and Figure 2 As shown, the air intake portion 2421 of the shell 24 described later is installed in the air supply device installation hole 13 of the clothing body 1 in such a manner that the air intake portion 2421 is located on the outer surface side of the clothing body 1 and the air outlet portion 2411 is located on the inner surface side of the clothing body 1.

[0048] A necessary voltage is supplied from the power supply device 3 to the air blowing device 2 via the power supply cable 4 .

[0049] like Figure 3 to Figure 6 As shown, the air supply device 2 includes: blades 21; a motor 22 for rotating the blades 21; a connecting line 23 for connecting the power cable 4 and supplying the voltage from the power supply device 3 to the motor 22; a shell 24 for accommodating the blades 21 and the motor 22; and a mounting ring 25, which is an annular component for fixing the shell 24 to the clothing body 1.

[0050] [a blade]

[0051] The blade 21 is a means for generating a flow of air from an air intake portion 2421 side toward an air delivery portion 2411 side of the housing 24 described later by being rotated by the motor 22 .

[0052] exist Figure 3 to Figure 6 , a case where a so-called propeller fan formed in a propeller shape is used as the blade 21 is illustrated, but the shape of the blade 21 is not particularly limited as long as it is a shape that can generate a flow of air from the air intake portion 2421 side of the housing 24 described later toward the air delivery portion 2411 side.

[0053] [b motor]

[0054] The motor 22 is a unit for rotating the blade 21, and is disposed at the center of the blade 21. The motor 22 receives a voltage supply from the power supply device 3, and rotates the blade 21 about an axis passing through the center of the air intake portion 2421 of the housing 24 and the center of the air delivery portion 2411 (with the same axis as the center of the air outlet portion 2411). Figure 1 and Figure 2As the motor 22, a brushless motor having no electrodes called "brush" inside is used.

[0055] like Figure 5 and Figure 6 As shown, the motor 22 includes an electric component 221 , a magnet 222 , and a bearing 223 .

[0056] The electric component 221 is a portion such as a coil in the motor 22 through which current flows when a voltage is supplied from the power supply device 3 .

[0057] The magnet 222 is a ring-shaped magnet. Figure 5 and Figure 6 As shown, it is configured to cover the electrical component 221.

[0058] The bearings 223 are components for supporting the rotating shaft of the electric component 221 , and are provided on both the front and rear sides of the electric component 221 .

[0059] The electric components 221 in the motor 22 are entirely sealed with resin and have waterproof properties.

[0060] Furthermore, when water does not penetrate into the interior when it is poured with water during washing, specifically, when it satisfies IP68, it has waterproof property.

[0061] The resin used to seal the motor 22 is not particularly limited as long as the above-mentioned waterproof property can be obtained, and ABS resin or the like can be used.

[0062] [c connecting cable]

[0063] The connecting wire 23 is a component for setting a power socket 231 for supplying voltage from the power supply device 3 to the motor 22 at a position away from the blade 21, the motor 22 and the housing 24. The connecting wire 23 is formed in a linear shape, one end of which is connected to the electrical component 221 of the motor 22, and the other end of which has a power socket 231 as a connection portion for connecting to the power plug 41 of the power cable 4.

[0064] The power socket 231 may be any socket that can be connected to the power plug 41 of the power cable 4 , and for example, a general DC socket may be used.

[0065] The connection line 23 has the same waterproofness as the electric component 221 of the motor 22 except the power socket 231. In addition, the connection part between the connection line 23 and the electric component 221 of the motor 22 is also configured to have the same waterproofness as the electric component 221 of the motor 22 by, for example, sealing with resin.

[0066] In addition, the power socket 231 can also have the same waterproofness as the electrical components 221 of the motor 22 by using a waterproof terminal, but as described later, since the air supply device 2 can be cleaned while only preventing water from splashing onto the power socket 231, the power socket 231 does not have to be waterproof.

[0067] [d Shell]

[0068] The housing 24 is a shell that contains the blades 21 and the motor 22. Figure 3 to Figure 6 As shown, it comprises: a housing 241 for accommodating the blade 21 and the motor 22; a finger guard 242 for covering an opening 2413 formed at one end of the housing 241; and a shielding plate 243 installed at the end of the housing 241 on the opposite side of the end where the finger guard 242 is installed.

[0069] [(a) Housing]

[0070] The housing 241 is a part of the main body of the housing 24 that contains the blades 21 and the motor 22. Figure 5 and Figure 6 As shown, it has: an air delivery portion 2411, which is a mesh-like portion that delivers air when the blade 21 is rotated; a cylindrical portion 2412, which is a cylindrical portion formed in a continuous manner from the air delivery portion 2411; an opening portion 2413, which is a circular opening portion formed on the surface opposite to the surface on which the air delivery portion 2411 is formed; and a flange 2414, which protrudes from the end of the cylindrical portion 2412 on the opening portion 2413 side in a direction approximately perpendicular to the side surface of the cylindrical portion 2412.

[0071] The cylindrical portion 2412 is formed into a cylindrical shape having a substantially circular cross-sectional shape when cut along a plane (YZ plane) perpendicular to the rotation axis (X axis) of the blade 21 , and its outer diameter is formed to be substantially the same as the diameter of the air supply device mounting hole 13 .

[0072] In addition, at two opposite locations on the outer surface of the cylindrical portion 2412, there are formed projections and depressions, namely, shell-side engaging portions 24121, which engage with projections and depressions formed on the inner surface side of the mounting ring 25 described later, namely, the mounting ring side engaging portion 251, thereby enabling the mounting ring 25 to be fixed to the outer surface side of the cylindrical portion 2412 as described later.

[0073] [(b) Finger guard]

[0074] The finger guard 242 is a component installed in a manner to cover the opening 2413 of the housing 241. Figures 4 to 6 As shown, the blade 21 is formed in a circular shape, and an air introduction portion 2421 is formed on the entire body except for the end portion. The air introduction portion 2421 is a mesh-like portion that introduces air when the blade 21 is rotated.

[0075] [(c) Shield]

[0076] The shielding plate 243 is a circular plate-shaped component, such as Figure 3 , Figure 5 as well as Figure 6 As shown, it is installed in a manner covering the central portion of the housing 241.

[0077] [e Mounting Ring]

[0078] The mounting ring 25 is an annular member integrally formed of a flexible material such as plastic. Figure 3 and Figure 4 As shown in the figure, the outer surface of the cylindrical portion 2412 of the shell 241 of the shell 24 is covered, and the portion around the air supply device installation hole 13 of the clothing body 1 is clamped between one end of the mounting ring 25 and the flange 2414 of the shell 241 of the shell 24, so that Figure 1 and Figure 2 As shown, the air supply device 2 is installed on the clothing body 1.

[0079] The mounting ring 25 is formed in an elliptical ring shape when viewed from the rotation axis direction (X-axis direction) of the blade 21. In addition, the mounting ring 25 is formed so that the length of the inner circumference is longer than the length of the outer circumference of the cylindrical portion 2412 of the outer shell 241 of the housing 24, and the short diameter of the inner circumference is smaller than the diameter of the outer circumference of the cylindrical portion 2412 of the outer shell 241 of the housing 24 or is the same as the diameter of the outer circumference of the cylindrical portion 2412 of the outer shell 241 of the housing 24. In this case, the long diameter of the inner circumference of the mounting ring 25 is larger than the diameter of the outer circumference of the cylindrical portion 2412 of the outer shell 241 of the housing 24.

[0080] In addition, at two opposing positions on the inner surface side of the mounting ring 25 in the short diameter direction, there are formed projections and depressions, namely mounting ring side fitting parts 251, which fit into projections and depressions, namely housing side fitting parts 24121, formed on the outer surface side of the cylindrical part 2412 of the outer shell 241 of the housing 24.

[0081] As described above, since the mounting ring 25 is flexible, when the mounting ring 25 is pressed from the outer surface side in the long diameter direction, the mounting ring 25 expands outward in the short diameter direction, and the mounting ring 25 can be deformed into a substantially perfect circular shape. In addition, when the force pressing from the outer surface side in the long diameter direction is released, the mounting ring 25 returns to its original elliptical shape.

[0082] By utilizing this, the elliptical mounting ring 25 is pressed from the outer surface side in the long diameter direction to bend and deform it into a substantially circular shape, and then the mounting ring side fitting portion 251 of the mounting ring 25 is overlapped with the housing side fitting portion 24121 of the cylindrical portion 2412, and after the mounting ring 25 is covered on the cylindrical portion 2412, the pressing of the mounting ring 25 is released, thereby Figure 3 and Figure 4 As shown, the mounting ring 25 can be mounted on the cylindrical portion 2412 of the outer shell 241 of the housing 24 .

[0083] At this time, the air supply device 2 can be attached to the clothing body 1 by sandwiching the portion around the air supply device attachment hole 13 of the clothing body 1 between one end of the attachment ring 25 and the flange 2414 of the outer shell 241 of the housing 24 .

[0084] [(3) Power supply device]

[0085] The power supply device 3 is a component for supplying power to the air supply device 2, and for example, has a lithium-ion battery pack with a safety protection circuit built in. Figure 1 As shown, the power supply device 3 is connected to the air blowing device 2 via the power supply cable 4. In addition, the power supply device 3 includes a switch for switching the power supplied to the air blowing device 2 on and off.

[0086] The specific structure of the power supply device 3 is arbitrary as long as it can supply electric power to the air blowing device 2 .

[0087] [(4) Power cable]

[0088] like Figure 1 As shown, the power cable 4 is a cable connecting the power supply device 3 and the air blowing device 2 , and the power required for the operation of the air blowing device 2 is supplied from the power supply device 3 to the air blowing device 2 through the power cable 4 .

[0089] like Figure 1 As shown, one end of the power cable 4 is forked into two branches, and both branches have power plugs 41. By inserting the power plug 41 into the power socket 231 of the connecting wire 23 of the air supply device 2, the power cable 4 can be freely connected to the air supply device 2.

[0090] The specific structure of the power plug 41 is not particularly limited as long as the power cable 4 can be freely connected to the air supply device 2 by inserting the power socket 231 of the connecting wire 23 of the air supply device 2 and the power required for the operation of the air supply device 2 can be supplied.

[0091] [Effects of 2nd Embodiment]

[0092] According to the fan-equipped clothing 100 of this embodiment, the air supply device 2 includes: blades 21 for generating air flow; a motor 22 for rotating the blades 21; and a housing 24 for accommodating the blades 21 and the motor 22, and the electric components 221 of the motor 22 are waterproof.

[0093] Thus, even if water is poured onto the air blowing device 2, the motor 22 is unlikely to fail, and thus the air blowing device 2 can be easily cleaned with water.

[0094] Furthermore, since the electric components 221 of the motor 22 of the air blowing device 2 are sealed with resin, the waterproof property of the motor 22 can be further improved.

[0095] In addition, the air supply device 2 has a connecting wire 23 connected to the electrical component 221 of the motor 22. The connecting wire 23 has a power socket 231 for supplying voltage from the power supply device 3 to the electrical component 221 at the end of the connecting wire 23 on the opposite side of the end connected to the electrical component 221. In addition to the electrical component 221, at least the portion of the connecting wire 23 other than the power socket 231 is also waterproof, thereby enabling the power socket 231 to be positioned away from the blades 21 and the housing 24 of the air supply device 2, making it easy to clean the air supply device 2 while only preventing water from splashing onto the power socket 231.

[0096] [3 Modifications]

[0097] Next, a modification of the fan-equipped garment 100 according to the present embodiment will be described.

[0098] [(1) Changes to articles with air supply devices]

[0099] In the description of the above structure and effect, the clothing 100 with a fan is described as an example of an article with an air supply device 2, but the article with an air supply device 2 can be any article as long as air is introduced into the main body through the air supply device 2, and is not limited to the clothing 100 with a fan.

[0100] For example, a cushion or bedding having the function of introducing air between two sheets to cool the contact portion between the sheets and the body, a helmet having the function of circulating air into the helmet to cool the wearer's head, a backpack having the function of introducing air into the backpack to cool the wearer's back, etc. may be provided with the air supply device 2. Any article is equivalent to the article with the air supply device in the present invention.

[0101] [(2) Addition of terminal cover]

[0102] It is also possible to provide a waterproof cover that covers the connection portion when the power socket 231 of the connection line 23 provided in the air supply device 2 is connected to the power plug 41 of the power cable 4. By using the cover to cover the connection portion between the power socket 231 and the power plug 41, the connection portion is given the same waterproofness as the electrical component 221 of the motor 22, so that when the power cable 4 is installed in the air supply device 2, the entire connection line 23 can be sprayed with water, and it becomes easier to clean the air supply device 2 with water when the power cable 4 is installed in the air supply device 2.

[0103] Industrial Applicability

[0104] The present invention can be suitably utilized in the field of manufacturing air blowers and articles equipped with air blowers.
