Description

[Technical field]

[0001] The present invention relates to a combination of a fan device and clothing for the fan device, and more particularly to a combination of a fan device and clothing for the fan device, in which the fan device is attached to clothing to cool the body. [Background technology]

[0002] 2. Description of the Related Art In recent years, there has been a demand for fan devices and clothing for fan devices that can be attached to clothing to cool the body.

[0003] One such device is the fan device, fan-equipped clothing, and fan body attachment tool disclosed in Patent Document 1. This is known as Air Conditioned Clothing (registered trademark), and has fan devices attached to two planar fan attachment holes provided on the left and right sides of the waist slightly toward the back of the clothing body, approximately halfway between the arms and the clothing body, and a large amount of outside air taken in by the fan devices is circulated approximately parallel to the surface of the body or underwear, evaporating sweat from the body and cooling the body.

[0004] The fan body has a cylindrical portion that is inserted into an attachment hole provided in the garment body and a flange portion that protrudes from one axial end of the cylindrical portion in a direction perpendicular to the axial direction of the cylindrical portion, and a fan attachment means that is attached to the fan body with the edge of the attachment hole of the garment body sandwiched between the flange portion and the outside of the cylindrical portion.The fan attachment means is attached to the outer periphery of the cylindrical portion so as to cover the entire circumference, and includes a ring member composed of a split body divided into two circumferentially, and a fixing member that fixes the circumferential ends of the two split bodies to each other, and is configured to fix the fan body to the garment body by fixing the two split bodies attached to the outer periphery of the cylindrical portion inserted into the attachment hole with the fixing member.

[0005] Another such device is a heat exchange unit and clothing equipped with the same, disclosed in Patent Document 2. This is clothing that uses Peltier elements to comfortably cool or heat the wearer's body, and the heat exchange unit includes a partition plate attached to the fabric of the clothing and separating the inside of the clothing from the outside of the clothing, a Peltier element attached to the partition plate, a first heat conductive member provided on the inside of the clothing of the partition plate and conducting heat from one side of the Peltier element, a first fan that diffuses air that has been heat exchanged by the first heat conductive member to the inside of the clothing, a second heat conductive member provided on the outside of the clothing of the partition plate and conducting heat from the other side of the Peltier element, and a second fan that releases air that has been heat exchanged by the second heat conductive member to the outside of the clothing.

[0006] Another such device is an air conditioning unit and clothing equipped with the same, disclosed in Patent Document 3. This uses Peltier elements to comfortably cool or heat the wearer's body, and a heat exchange plate is placed in direct or indirect contact with the area from between the shoulder blades to the waist of the user, allowing the area to be cooled or heated efficiently.

[0007] This air conditioning unit and clothing equipped with it are capable of efficiently cooling or heating the user's body by utilizing a Peltier element, and the air conditioning unit for cooling or heating the user's body comprises a Peltier element, a metal plate joined to one side of the Peltier element, a metallic heat exchange plate which is larger in area than the metal plate and is positioned on the body side while joined to the metal plate, a heat sink which is positioned on the other side of the Peltier element, a fan which is positioned opposite the heat sink and which releases heat from the heat sink to the outside, and a fan cover which is attached to cover the heat sink and fan.

[0008] In particular, when an air conditioning unit is attached to clothing for cooling purposes in the summer, the skin temperature of the body is about 33°C, whereas the metal heat exchange plate is often at a lower temperature than the skin temperature. Therefore, when the user is wearing the clothing, the body touches the heat exchange plate, giving the user a certain sense of coolness. However, the sense of coolness obtained when wearing the clothing is temporary, and when the Peltier element is not driven, the heat exchange plate gradually rises to the same temperature as the skin temperature of the body. On the other hand, when the Peltier element is driven immediately after wearing the clothing, the Peltier element starts to cool the heat exchange plate before the heat exchange plate starts to rise in temperature. Therefore, the temperature rise of the heat exchange plate can be suppressed. In other words, when used for cooling purposes in the summer, it is sufficient for the Peltier element to absorb the heat of the heat exchange plate so as to suppress the temperature rise of the heat exchange plate. Therefore, the above-mentioned air conditioning unit has the advantage that it is possible to give the user a sense of coolness from the time of wearing the clothing without increasing the power consumption of the Peltier element, and that the sense of coolness can be maintained for a long time.

[0009] Another such device is the Peltier vest disclosed in Non-Patent Document 1. This device has a large fan attached to a fan attachment hole on the back of the vest, and obtains a cooling effect by taking in outside air through the heat of vaporization, while a large flat plate cooled by Peltier element technology is placed in close contact with the user's back, continuously cooling the back at a temperature 15 degrees below the outside temperature. [Prior art documents] [Patent documents]

[0010] [Patent Document 1] JP 2023-21758 A [Patent Document 2] JP 2020-97799 A [Patent Document 3] JP 2022-63478 A [Non-patent literature]

[0011] [Non-Patent Document 1] Peltier Vest "Refrigerated Clothing" [Searched on April 11, 2023], Internet: https: / / www.thanko.co.jp / shopdetail / 000000001214 / Summary of the Invention [Problem to be solved by the invention]

[0012] However, the technology described in Patent Document 1 has the disadvantage that, although it can cool the body by evaporating sweat from the body by circulating a large amount of outside air taken in by the fan device, it cannot cool the body any further.

[0013] In addition, with the technology described in Patent Document 2, although the heat-exchanged air can be diffused to the inside of the garment using a fan, it is not possible to take in outside air, and therefore even if sweat from the body evaporates, the humid air cannot be released to the outside, resulting in the inconvenience of not being able to achieve the effect of cooling the body by evaporating sweat.

[0014] Furthermore, in the technology described in Patent Document 3, when an air conditioning unit is attached to clothing for cooling purposes in summer, the fan is configured to release heat from the heat sink to the outside, but is not configured to take in outside air, so when cooling the user's body, there is the inconvenience that the fan cannot evaporate sweat from the body and cool the user's body with the latent heat of vaporization.

[0015] In addition, in the technology described in Non-Patent Document 1, as described in Non-Patent Document 1, a flat plate is attached to the back of the user to continuously cool the back. In this case, when the Peltier element is first activated, even if there is a large temperature difference between the plate and the outside air temperature, the body is a large heat source, and if it is attached to the back and used continuously, the temperature difference between the heat exchange plate and the body becomes smaller even if it is cooled by the Peltier element, and the initial cooling sensation is gradually lost. Also, as described in the "Frequently Asked Questions" in Non-Patent Document 1, even if it is used over clothes, there is an inconvenience that there is a risk of frostbite if it is used in a situation where the outside air temperature is low or the cooling plate temperature is below zero.

[0016] To provide a combination of a fan device and clothing for a fan device, which is attached to clothing to cool the body, takes in outside air to obtain a cooling effect due to the heat of vaporization, and cools the body using a Peltier element, and which can maintain a cool or refreshing feeling even when used continuously. [Means for solving the problem]

[0017] In order to solve the above problems, the present invention employs the following configuration.

[0018] The present invention relates to a combination of a fan device and clothing for a fan device that takes in outside air to evaporate sweat from the user's body, thereby obtaining a cooling effect through the heat of vaporization, and cools the body using a Peltier element. and, Fan unit wear The wear body has a mounting hole for mounting a fan device, and the fan device has a housing part with a mounting part for mounting the fan device in the mounting hole, and a fan cooling part and a Peltier cooling part held in the housing part, and the fan of the fan cooling part cools the housing part. Intake holeThe Peltier cooling unit has a Peltier element, a cooling plate on the body side with the Peltier element in between, and a heat sink on the intake side, and is configured to dissipate heat from the heat sink using the outside air taken in by the fan and to cool the cooling plate using the Peltier element. The cooling plate is configured to bulge out from the housing towards the body. The wear body has a deflection that allows the fan device to move at least in the axial direction when the fan device is attached, and the wear body is configured to bend when the user moves their body. When the cooling plate is not in use, the fan unit moves due to the presence of deflection due to the force of expelling the outside air taken in by the fan toward the body, and the cooling plate is cooled in a state where it is separated from the body, thereby indirectly cooling the body; and when the user moves the body by raising their arms or twisting their body, the deflection is pulled by the movement of the body and decreases, so that the fan unit moves toward the body against the force expelling the outside air toward the body, and the cooling plate comes into direct contact with the body to cool it.

[0019] In addition, the fan device wear covers the upper body of the user, with the lower end configured to fit closely around the waist of the user, and the attachment holes are provided near the left and right sides of the user, one on each side, near the lower end of the fan device wear.

[0020] In addition, an exhaust guard is provided at the exhaust hole to prevent fingers or other objects from entering the inside of the fan device, the exhaust guard is configured to bulge on the exhaust side of the fan device, and the cooling plate is fixed to the top of the exhaust guard and configured so that the exhaust side surface bulges further toward the exhaust side than the exhaust guard.

[0021] The exhaust guard has a plurality of exhaust guard arms formed in a substantially radial pattern from the top to the outer periphery, and the heat sink has a plurality of heat dissipation arms formed in a substantially radial pattern on the outer periphery, Exhaust guard armThe present invention is characterized in that the shape of the projection is substantially overlapped with the projection shape when viewed from the axial direction.

[0022] The device is also characterized in that the mounting holes are provided at positions approximately directly below the left and right arms of the user, one on each side.

[0023] The fan device has a controller connected to the fan device by a connection cable and supplies power to the fan device, the controller having a control unit that switches between a plurality of voltages to control the capacity of the battery, the fan cooling unit, and the Peltier cooling unit; controller The cooling device is characterized in that the fan cooling section and the Peltier cooling section are supplied with power of the same voltage.

[0024] The fan device has a temperature sensor and is configured to stop cooling the Peltier cooling portion when the cooling plate or the outside air falls below a predetermined temperature. Effect of the Invention

[0025] According to the present invention, since it has the above-mentioned characteristics, it is possible to achieve the following.

[0026] A combination of a fan device and a wearable fan device that takes in outside air to evaporate sweat from the user's body and obtain a cooling effect by the heat of vaporization, and cools the body by a Peltier element, Fan unit wear The wear body has a mounting hole for mounting a fan device, and the fan device has a housing part with a mounting part for mounting the fan device in the mounting hole, and a fan cooling part and a Peltier cooling part held in the housing part, and the fan of the fan cooling part cools the housing part. Intake holeThe Peltier cooling section has a Peltier element, a cooling plate on the surface facing the body and a heat sink on the surface facing the intake side, with the Peltier element sandwiched between them, and is configured to dissipate heat from the heat sink using the outside air taken in by the fan and to cool the cooling plate using the Peltier element. The cooling plate is configured to bulge out from the housing towards the body. With the fan device attached, the wear body has a deflection that allows the fan device to move at least in the axial direction, and when the user is not moving, the force of discharging the outside air taken in by the fan to the body dissipates heat. The fan device moves due to the deflection, and the cooling plate is cooled when it is separated from the body, so that the body is indirectly cooled. When the user moves the body by raising the arm or twisting the body, the deflection is pulled by the movement of the body and reduced, so that the fan device moves toward the body against the force of discharging outside air to the body, and the cooling plate comes into direct contact with the body to cool the body. Therefore, when the user is not moving, the fan device attached to the wear can be lifted up and separated from the body by the force of pushing out the air from the fan. When the fan device is separated from the body, the cooling plate is not directly heated by the body as when it is in contact with the body, but is cooled by the inherent cooling power of the Peltier element. Then, the sufficiently cooled cooling plate can cool the air inside the wear. When the user moves the body, the sufficiently cooled cooling plate comes into direct contact with the body, providing a cool or refreshing feeling. Furthermore, when the user stops moving, the fan device rises up and separates from the body, allowing the cooling plate to cool to its original temperature. Therefore, even with continued use, the cooling sensation can be maintained.

[0027] In addition, the fan device wear covers the upper body of the user and is configured with its lower end fitting snugly around the user's waist, and the mounting holes are provided near the left and right sides of the user, one on each side near the lower end of the fan device wear. Therefore, for example, if the fan device is located approximately halfway between the arm and the lower end of the fan device wear, the amount of bending is large and the fan device is far away from the body, making it difficult for the cooling plate to come into contact with the body even when the body is moved, such as by raising the arm. On the other hand, if the fan device wear is located near the lower end of the fan device wear, the lower end is configured to fit snugly around the user's waist, so there is less bending, the fan is close to the body, and the cooling plate is more likely to come into contact with the body when the body is moved.

[0028] In addition, an exhaust guard is provided at the exhaust hole to prevent fingers or other objects from getting inside the fan device. The exhaust guard is configured to bulge towards the exhaust side of the fan device, and the cooling plate is fixed to the top of the exhaust guard and configured so that the exhaust side surface bulges further towards the exhaust side than the exhaust guard. Therefore, when the user is not moving, the fan device can be easily lifted up and separated from the body, and when the user moves, the cooling plate can be easily brought into contact with the body.

[0029] The exhaust guard has a plurality of exhaust guard arms formed in a substantially radial pattern from the top to the outer periphery, and the heat sink has a plurality of heat dissipation arms formed in a substantially radial pattern on the outer periphery, Exhaust guard arm Since the fan is configured to substantially overlap with the projected shape when viewed from the axial direction, heat can be efficiently dissipated by the outside air taken in by the fan, cooling the cooling plate and exhausting the heat into the wear.

[0030] In addition, since the mounting holes are provided at positions approximately directly below the user's left and right arms, the fan unit does not come into contact with the driver's seat of the forklift or tractor, making it convenient to use even when working while sitting in the driver's seat.

[0031] The fan device has a controller connected to the fan device by a connection cable and supplies power to the fan device, the controller having a control unit that switches between a plurality of voltages to control the capacity of the battery, the fan cooling unit, and the Peltier cooling unit; controller Since the fan cooling section and the Peltier cooling section are configured to receive power of the same voltage, it is possible to synchronize the cooling by the fan cooling section and the cooling by the Peltier cooling section to control their capacity, and it also simplifies the wiring from the power supply section.

[0032] Furthermore, the fan device has a temperature sensor and is configured to stop cooling the Peltier cooling section when the cooling plate or the outside air temperature falls below a specified temperature, making it possible to obtain a fan device that is even less likely to cause frostbite.

[0039] Next, the configuration of the fan device 2 will be described with reference to FIGS. FIG. 3 is a perspective view showing the fan device 2 before it is attached to the garment 1. As shown in FIG. As shown in FIG. 3, the fan device 2 has an intake guard portion (mounting portion) (housing portion) 3 and a fan device main body (housing portion) 4.

[0040] As shown in FIG. 3, the fan device main body 4 has a cylindrical main body portion 5, an exhaust guard portion 6, and a main body control portion 7 that bulges out from the cylindrical main body portion 5 in the lateral direction. The exhaust guard portion 6 is formed in a shape that bulges toward the exhaust side, and the exhaust side surface of the cooling plate (cooling plate) 81 of the Peltier cooling portion (Peltier cooling portion) 8 is fixed to the top so that it bulges further toward the exhaust side. The main body control unit 7 has a small, roughly box-like shape and has a connection plug 71 for connecting a connection cable from the controller C, a Peltier switch 72 for switching the operation of the Peltier cooling unit 8, and a Peltier operation display 73 for displaying the operation of the Peltier cooling unit 8.

[0041] Fig. 4 is a cross-sectional view of the fan device 2 attached to the clothing 1, taken along line AA in Fig. 3, and Fig. 5 is an exploded perspective view of the fan device main body 4. That is, Fig. 4 is a cross-sectional view of the fan device 2 cut to show the screwed and engaged state of the fan device 2. The internal configuration of the fan device 2 and the fan device main body 4 will be described in detail below with reference to FIGS.

[0042] 4 and 5, the tubular main body 5 has a tubular main body 51 formed in a substantially cylindrical shape, and the outer surface of the tubular main body 51 is uneven so that it is easy to grip with fingers when screwing into the intake guard part 3. In addition, a plurality of cable stoppers 52 with a substantially L-shaped cross section are formed on the outer surface of the tubular main body 51 for fastening a connection cable from the controller C. A main body flange part 53 is formed on the outer periphery on the intake side of the tubular main body 51, and a female screw part 54 for screwing into the male screw part 35 of the intake guard part 3 is formed on the inner periphery.

[0043] In addition, a fan holding portion 56 having a shallow cylindrical shape with a bottom is formed on the inner surface on the exhaust side of the main body cylindrical portion 5 and is held by four fan holding arms 55, and a motorized fan (fan cooling portion) (fan) 9 is fixed to the fan holding portion 56. The exhaust side inner surface of the tubular main body part 5 is formed with a plurality of stopper parts 57 which act as stoppers when assembling with the exhaust guard part 6 described below, and engagement claws 58 for engaging with the exhaust guard part 6. In addition, the outer surface of the tubular main body part 5 is formed with a small box-shaped main body control part storage part 59 which bulges out laterally and is open on the exhaust side for storing the circuit board etc. of the main body control part 7.

[0044] 4 and 5, exhaust guard portion 6 is formed with exhaust hole (exhaust hole) 62 covered with exhaust guard 61 (exhaust guard) that bulges out towards the exhaust side, and a disk-shaped Peltier holder 64 having a square Peltier holder hole 63 in the center is formed at the top of exhaust guard 61. An exhaust cylinder portion 65 is provided on the intake side of exhaust guard portion 6, and the exhaust side end portion of exhaust cylinder portion 65 and Peltier holder 64 are connected by a plurality of curved exhaust guard arm portions (exhaust guard arm portions) 66 formed radially to form exhaust guard 61.

[0045] Exhaust tube portion 65 is formed in a cylindrical shape, and a plurality of engaged portions 67 that engage with engaging claws 56 are formed on the intake side of exhaust tube portion 65 so as to protrude from exhaust tube portion 65 to the intake side. A main body control portion storage portion lid portion 68 that bulges out laterally and serves as a lid for the exhaust side of main body control portion storage portion 59 is formed on the exhaust side end of exhaust tube portion 65.

[0046] 4 and 5, the Peltier cooling unit 8 has a cooling plate 81, a Peltier element (Peltier element) 82, and a heat sink (heat sink) 83. The exhaust side surface of the cooling plate 81 is formed in a shape that bulges out toward the exhaust side, and is configured to bulge further out toward the exhaust side from the top of the exhaust guard 61 that bulges out toward the exhaust side. Here, the cooling plate 81 and the heat sink 83 are made of a metal with high thermal conductivity, such as aluminum.

[0047] As shown in Fig. 4, two bosses 84, 84 with screw holes are formed on the intake side surface of the cooling plate 81. The Peltier element 82 is stored in the Peltier holding hole 63, and the cooling plate 81 is attached to the exhaust side surface of the Peltier element 82 via a heat transfer sheet 85, and the heat sink 83 is attached to the intake side surface. Then, when two screws are screwed into the bosses 84, 84 from the intake side, the Peltier cooling unit 8 is integrated and firmly fixed to the Peltier holding unit 64. Here, heat transfer grease is applied to the contact surfaces of the heat sink 83, heat transfer sheet 85, Peltier element 82, and cooling plate 81, respectively, to ensure good heat transfer.

[0048] 5, a plurality of curved radially shaped heat dissipating arms (heat dissipating arms) 86 are formed on the outer periphery of the heat dissipating plate 83. Here, the plurality of heat dissipating arms 86 are formed so as to substantially overlap with the projected shape of the exhaust guard arm 66 of the exhaust guard part 6 when viewed from the axial direction, so that it is possible to efficiently dissipate heat from the heat dissipating plate 83 using the outside air taken in by the fan, cool the cooling plate 81 by the Peltier element 82, and exhaust the heat into the wear.

[0049] As shown in Fig. 4, the outer diameter of the exhaust tubular portion 65 of the exhaust guard portion 6 is sized to fit into the inner diameter of the tubular portion main body 51 of the main body tubular portion 5. Then, as shown in Figs. 4 and 5, when the intake side of the exhaust guard portion 6 is inserted into the exhaust side of the main body tubular portion 5, the intake side end face of the exhaust tubular portion 65 abuts against the stopper portion 57, and the engaged portion 67 protruding from the intake side end face engages with the engaging claw 58. In this way, the main body tubular portion 5 and the exhaust guard portion 6 are integrated, and the fan device main body 4 is assembled.

[0050] Here, how the fan device 2 is attached to the wear 1 will be described with reference to FIG. 4, first, the intake cylinder portion 34 of the intake guard portion 3 is inserted into the mounting hole of the garment 1. Next, the fan device main body 4 is abutted against the intake guard portion 3, and when they are rotated relative to each other, the male thread portion 35 screws into the female thread portion 52 of the fan device main body 4. In this way, the portion around the mounting hole of the garment 1 is firmly sandwiched between the intake flange portion 33 and the main body flange portion 51, and the fan device 2 is fixed to the garment 1.

[0051] Next, how the combination of the fan device 2 and the wear 1 for the fan device works when the wear 1 is attached with the fan device 2 and used by a user U will be described.

[0052] As described above, the wear 1 of this embodiment is generally in the shape of long-sleeved work clothes, and the lower end is configured to fit closely around the waist of the user U. Near the lower end of the wear 1, near the left and right sides of the waist slightly toward the back of the user U, fan devices 2, 2 are attached, and the outside air sucked in by the fan devices 2, 2 inflates the wear 1, so that the outside air spreads inside the wear 1, evaporates sweat from the user U's body, cooling the body, and is discharged from the neck and cuffs. At the same time, the heat of the heat sink 83 warmed by the Peltier element 82 is radiated by the sucked in outside air, and the cooling plate 81 is cooled.

[0053] Here, in the case of a configuration in which the cooling plate 81 is brought into direct contact with the body of the user U to provide a cooling sensation to the user U, as in the technology described in Non-Patent Document 1, the cooling plate 81 is sufficiently cooled at the beginning of use, providing the user U with a sufficient cooling sensation. However, the body is a large heat source, and with continued use, the heat exchange plate continues to be warmed by the body due to contact with the body, even if it is cooled by the Peltier element 82. Then, there is an inconvenience that the temperature difference between the heat exchange plate and the body or the outside air temperature becomes smaller, and the initial cooling sensation is gradually lost.

[0054] The wear 1 of this embodiment has a degree of flexure that allows the fan device 2 to move at least in the axial direction when the fan device 2 is attached. Therefore, when the user U is not moving, the fan device 2 moves upward due to the flexure caused by the force of the outside air taken in by the motorized fan 9 being released to the body. Then, the cooling plate 81 is separated from the body, so that the cooling plate 81 is not continuously heated by the body, which is a large heat source, but is sufficiently cooled by the Peltier element 82. The sufficiently cooled cooling plate 81 cools the air inside the wear 1 and radiates cool air to cool the part of the body near the cooling plate 81. Also, the outside air is cooled and condensation forms on the cooling plate 81.

[0055] Furthermore, when the user U moves his / her body by raising his / her arms or twisting his / her body, the deflection is pulled by the movement of the body and reduced, so that the fan device 2 moves toward the body against the force of the outside air being discharged to the body. Then, the cooling plate 81, which has been sufficiently cooled, comes into contact with the body, and the user U can feel a great sense of coolness. Note that the user U normally wears the wear 1 over his / her clothes, but when the user U moves his / her body, the condensation on the cooling plate 81 adheres to the clothes worn by the user U, and this condensation evaporates due to the intake of outside air, so that the user U can feel a great sense of coolness.

[0056] Then, when the user U stops moving, the fan device 2 attached to the wear 1 again rises up and separates from the body due to the force of pushing out the air. Then, the cooling plate 81 also separates from the body, and the cooling plate 81 is not directly heated by the body as when it is in contact with the body, but is cooled by the inherent cooling power of the Peltier element. Then, the cooling plate 81 is sufficiently cooled, and it becomes possible to cool the air inside the wear. Then, when the user U moves his / her body, the sufficiently cooled cooling plate 81 comes into contact with the body, providing a cool or refreshing feeling. When the user U stops moving, the fan device 2 rises up and separates from the body, and the cooling plate 81 is cooled to its original temperature. Therefore, even if the wearer continues to use the wear, the cool or refreshing feeling can be maintained.

[0057] In this way, the combination of the fan device 2 and the wear 1 for the fan device of this embodiment is used by the user U when performing work or the like, and allows the user U to feel a greater sense of coolness when moving his or her body. This provides the user with an incentive to move his or her body, and supports the user U in feeling the enjoyment of moving his or her body through work or the like, even during extremely hot weather.

[0058] The wear 1 covers the upper half of the user's body, and is configured such that its lower end fits closely around the waist of the user U, and the mounting holes are provided near the left and right sides of the user U, near the lower end of the wear 1. For example, if the fan device 2 is located approximately midway between the arm and the lower end of the wear 1, the amount of bending is large and the fan device 2 is far away from the body, so that even if the user moves the body by raising the arm, the cooling plate 81 is unlikely to come into contact with the body. Here, the fan device 2 of this embodiment is located near the lower end of the wear 1, and is configured such that its lower end U fits closely around the waist of the user, so that the amount of bending is small, the fan device 2 is close to the body, and the cooling plate 81 is likely to come into contact with the body when the user moves the body.

[0059] Further, an exhaust guard 61 is provided at the exhaust hole 62 to prevent fingers or the like from entering the inside of the fan device 2, and the exhaust guard 61 is configured to bulge towards the exhaust side of the fan device 2. The cooling plate 81 is fixed to the top of the exhaust guard 61, and is configured so that the surface on the exhaust side bulges further than the exhaust side of the fan device 2. Therefore, when the user U is not moving, the fan device 2 can be easily lifted up and separated from the body, and when the user moves, the cooling plate 81 can be easily brought into contact with the body.

[0060] Also, the fan devices 2, 2 are supplied with power from the controller C by changing the voltage of the power supply, but the motorized fan 9 and the Peltier element 82 are configured to be supplied with power of the same voltage. This makes it possible to synchronize the cooling by the motorized fan 9 and the cooling by the Peltier element 82 and control their capacity, while simplifying the wiring from the power supply. Of course, it is also possible to apply separate voltages to the motorized fan 9 and the Peltier element 82, although this will complicate the wiring.

[0061] In this embodiment, the fan device 2 is attached to the garment 1 by dividing the fan device 2 into the intake guard portion 3 and the fan device main body 4, which are assembled and attached to the attachment hole of the garment 1, but the present invention is not limited to this. For example, as shown in Patent Document 1, it goes without saying that the fan device 2 may be attached to the garment 1 by inserting the cylindrical fan device 2 into the attachment hole and fitting a ring member thereto.

[0062] Furthermore, in this embodiment, the shape of the wear 1 is roughly that of long-sleeved work clothes that cover the upper body of the user U, but the shape is not limited to this. For example, it goes without saying that the wearer may have the attachment holes of this embodiment provided in various shapes of fan-equipped wear currently available on the market.

[0063] Furthermore, it is of course possible to provide a temperature sensor such as a thermistor in the fan device 2 so that the cooling of the Peltier cooling unit 8 is stopped when the cooling plate 81 or the outside air temperature drops below a predetermined temperature. Originally, when the body is not moving, the cooling plate 81 is away from the body, making it difficult to get frostbite, but by stopping the cooling of the Peltier cooling unit 8 at low temperatures, it becomes even more difficult to get frostbite.

[0064] Second Embodiment A second embodiment of the present invention will now be described with reference to FIG. In the second embodiment, the fan device 2 has a similar configuration to that of the first embodiment, but the wear 1 has a different configuration. In the following, the same parts as those in the first embodiment are given the same reference numerals, and the description will be omitted, and only the different parts will be described.

[0065] As shown in Fig. 6, the wear 1 covers the upper body of the user U in the same manner as in the first embodiment, and the lower end is configured to fit closely around the waist of the user U with rubber or the like, and attachment holes are provided near the lower end of the wear 1, but the positions are different. In the first embodiment, the attachment holes were provided near the left and right sides of the user U slightly on the back side, but in this embodiment, they are provided near the sides approximately directly below the left and right arms. Also, while the wear 1 in the first embodiment had long sleeves, in this embodiment it is sleeveless and vest-like.

[0066] The mounting hole, i.e., the fan unit 2 is mounted near the bottom end of the garment 1, near the sides of the user U and approximately directly below the left and right arms, in order to make it easy to use even when the user is sitting in the driver's seat, such as when operating a forklift. When operating a forklift, if the fan unit 2 is mounted slightly toward the back, it may come into contact with the driver's seat of the forklift, compressing the worker's body, or the driver's seat may prevent the intake of outside air. To alleviate this, the fan unit 2 is mounted approximately directly below the left and right arms.

[0067] In this case, if the fan device 2 is attached approximately halfway between the arm and the garment body, the elbow will hit the fan device 2 when the arm is moved. In this embodiment, the fan device 2 is attached near the lower end of the garment 1, so that the elbow can be prevented from hitting the fan device 2 even when the arm is moved. This mounting position allows for convenient use when operating a tractor in agricultural work, etc., or when working while sitting on a chair with a backrest.

[0068] The installation position of the fan device 2 is located approximately directly below the left and right arms of the user U, which is convenient not only when driving a forklift or the like, but also when two people are riding on a motorcycle. That is, if the fan device 2 is installed slightly toward the rear, the intake of air by the fan device 2 may be blocked by the person behind.

[0069] The wear 1 is also made sleeveless and vest-like in order to accommodate work in which it is easier to move the arms without sleeves. Generally, the armpits are a place where sweat tends to accumulate, and when a user is wearing the vest-like wear 1 and working in a hot environment and raises their arms, a large amount of outside air is sucked in and taken in by the fan devices 2, 2 and discharged from the armpits. The discharged outside air then evaporates and cools the sweat coming out of the user U's armpits, providing the user U with a great feeling of coolness.

[0070] In any case, the combination of the fan device 2 and the wear 1 of this embodiment also allows the wearer to maintain a cool or refreshing feeling even when used continuously. The user U can use it when performing work, etc., and feel a greater sense of coolness when moving his / her body, so it can help the user U to feel the enjoyment of moving his / her body to work, even during extreme heat.

[0071] The combination of the fan device 2 and the wear 1 in the above-described embodiment can also be expressed as follows. This is a combination of a fan device and clothing for the fan device that obtains a cooling effect through the latent heat of vaporization by taking in outside air and also uses the taken-in outside air to dissipate heat from the heat sink of a Peltier element and cool the cooling plate.When the user is not moving, the force of the taken-in outside air being released onto the body causes the fan device to move the deflection of the clothing for the fan device, and the cooling plate becomes cold as it moves away from the body, indirectly cooling the body.When the user moves the body, the deflection decreases and the fan device moves towards the body against the force of the outside air being released onto the body, and the cooling plate comes into direct contact with the body to cool the body.When the user is not moving, the cooling plate becomes cold as it moves away from the body. This combination of a fan device and clothing for the fan device is configured in such a way that

[0072] The combination of the fan device and the wear for the fan device of the present invention is not limited to the embodiment described above and shown in the drawings, and various modifications can be made without departing from the spirit and scope of the present invention. For example, in the above embodiment, the case where the user U performs work has been described, but the present invention is not limited to this. For example, the device can be conveniently used when performing leisure activities such as cycling and fishing, sports, etc. [Explanation of symbols]
