The present invention relates to a combination of a fan device and clothing for the fan device. More specifically, the present invention relates to a combination of a fan device and clothing for the fan device, in which the fan device is attached to the clothing to cool the body.

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.

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 two flat fan attachment holes attached to each of the two sides of the waist slightly toward the back of the clothing body, approximately halfway between the arms and the clothing body. The fan device takes in a large amount of outside air and circulates it approximately parallel to the surface of the body or underwear, evaporating sweat from the body and cooling the body.

The fan includes a fan body having a cylindrical portion inserted into an attachment hole provided in the garment body and a flange portion protruding 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 attached to the fan body with the edge of the attachment hole of the garment body sandwiched between the flange portion and the outer side 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 divided body divided into two in the circumferential direction, and a fixing member that fixes the circumferential ends of the two divided bodies to each other. The two divided bodies attached to the outer periphery of the cylindrical portion inserted into the attachment hole are fixed by the fixing member to fix the fan body to the garment body.

As another such device, there 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 is equipped with 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.

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

This air conditioning unit and the wearable 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 that is larger in area than the metal plate and is placed on the body side while joined to the metal plate, a heat sink placed on the other side of the Peltier element, a fan that is placed opposite the heat sink and releases heat from the heat sink to the outside, and a fan cover that is attached to cover the heat sink and the fan.

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 begins to cool the heat exchange plate before the heat exchange plate begins 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.

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 by taking in outside air it creates a cooling effect 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 to a temperature 15 degrees below the outside temperature.

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

In addition, the technology described in Patent Document 2 can diffuse the air that has been heat exchanged into the inside of the garment using a fan, but cannot take in outside air. Therefore, even if sweat from the body evaporates, the air containing the moisture cannot be released to the outside, so there is an inconvenience in that the effect of cooling the body by evaporating sweat cannot be expected.

In addition, in the technology described in Patent Document 3, when an air conditioning unit is attached to clothing for cooling purposes in the 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.

In addition, the technology described in Non-Patent Document 1 involves placing a flat plate against the user's back as described in Non-Patent Document 1 to continuously cool the back. When the Peltier element is first activated, the plate has a large temperature difference from the outside air temperature, but the body is a large heat source, and if the plate is placed against the back and used continuously, the temperature difference between the heat exchange plate and the body becomes smaller even when 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 the plate is used over clothing, there is an inconvenience of a risk of frostbite if the plate is used in a situation where the outside air temperature is low or where the cooling plate temperature is below zero.

The object of the present invention is to provide a combination of a fan device and clothing for a fan device that 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 that can maintain a cool or refreshing feeling even with continuous use.

To solve the above problems, the present invention adopts the following configuration.

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.
The garment body of the fan device wear has an attachment hole for attaching the fan device, and the fan device has a housing section equipped with an attachment section for attaching the fan device to the attachment hole, and a fan cooling section and a Peltier cooling section held in the housing section, and is configured so that the fan of the fan cooling section takes in outside air through the intake hole of the housing section and expels the outside air to the body through the exhaust hole of the housing section, and the Peltier cooling section has a Peltier element, a cooling plate on the surface facing the body with the Peltier element in between, and a heat sink on the surface facing the intake side, and is configured so that the outside air taken in by the fan dissipates heat from the heat sink and the cooling plate is cooled by the Peltier element, and the cooling plate bulges out from the housing section towards the body side. The garment body is configured such that, with the fan unit attached, the fan unit has a degree of flexure that allows the fan unit to move at least in the axial direction, and when the user is not moving, the fan unit moves due to the flexure due to the force of releasing the outside air taken in by the fan onto 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 flexure is pulled down by the movement of the body and reduces, so that the fan unit moves towards the body against the force of releasing the outside air onto the body, and the cooling plate comes into direct contact with the body to cool the body.

The fan device wear covers the upper body of the user, with the lower end adapted to fit snugly around the waist of the user, and the attachment holes are provided near the left and right sides of the user, one each near the lower end of the fan device wear.

The exhaust hole is also provided with an exhaust guard to prevent fingers or other objects from entering the inside of the fan device, and the exhaust guard is configured to bulge out towards the exhaust side of the fan device, and the cooling plate is fixed to the top of the exhaust guard, with the exhaust side surface configured to bulge out further towards the exhaust side than the exhaust guard.

The exhaust guard has a plurality of exhaust guard arms formed approximately radially from the top toward the outer periphery, and the heat sink has a plurality of heat dissipation arms formed approximately radially on the outer periphery, and the heat dissipation arms are configured to approximately overlap with the projected shape when viewed from the axial direction of the exhaust guard arms .

Another feature is that the attachment holes are provided at positions approximately directly below the user's left and right arms.

The fan device is also connected by a connection cable and has a controller that supplies power to the fan device, and the controller has 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, and is configured so that the controller supplies power of the same voltage to the fan cooling unit and the Peltier cooling unit.

The fan device has a temperature sensor and is configured to stop cooling the Peltier cooling unit when the cooling plate or the outside air falls below a predetermined temperature.

The present invention has the above-mentioned characteristics, which makes it possible to achieve the following:

A combination of a fan device and clothing for the fan device, which takes in outside air to evaporate sweat from the user's body and obtain a cooling effect due to the heat of vaporization, and cools the body by a Peltier element, the clothing body for the fan device having a mounting hole for mounting the fan device, and the fan device having a housing part with a mounting part for mounting the fan device to the mounting hole, and a fan cooling part and a Peltier cooling part held in the housing part, the fan of the fan cooling part is configured to take in outside air from the intake hole of the housing part and release the outside air to the body from the exhaust hole of the housing part, the Peltier cooling part has a Peltier element, and a cooling plate on the surface facing the body with the Peltier element between them and a heat sink on the surface facing the intake side, the outside air taken in by the fan dissipates heat from the heat sink, and the cooling plate is cooled by the Peltier element, the cooling plate bulges out from the housing part towards the body The garment body is configured so that, when the fan unit is attached, the fan unit has a deflection that allows the fan unit to move at least in the axial direction, and when the user is not moving, the fan unit moves due to the deflection due to the force of discharging the outside air taken in by the fan to the body, and the cooling plate is cooled in a state where the cooling plate 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 of discharging the outside air to the body, and the cooling plate comes into direct contact with the body to cool the body, so that when the user is not moving, the fan unit attached to the garment can be lifted up and separated from the body by the force of the fan pushing out the air. If the fan unit 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 garment. In addition, when the user moves, the sufficiently cooled cooling plate comes into direct contact with the body, providing a cool and refreshing sensation. When the user stops moving, the fan device lifts up and separates from the body, so the cooling plate cools to its original temperature. Therefore, the cool and refreshing sensation can be maintained even with continuous use.

The fan device wear covers the upper body of the user, and is configured so that the lower end fits snugly around the waist of the user, and the mounting holes are provided near the left and right sides of the user's abdomen, one each near the lower end of the fan device wear. 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 waist of the user, 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.

The exhaust hole is also fitted with an exhaust guard 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, with the exhaust side surface configured to bulge further towards the exhaust side than the exhaust guard. This makes it easy to lift the fan device away from the body when the user is not moving, and easy to bring the cooling plate into contact with the body when the user does move.

In addition, the exhaust guard has a plurality of exhaust guard arms formed approximately radially from the top toward the outer periphery, and the heat sink has a plurality of heat dissipation arms formed approximately radially on the outer periphery, and the heat dissipation arms are configured to approximately overlap with the projected shape when viewed from the axial direction of the exhaust guard arms , so that heat can be efficiently dissipated by the outside air taken in by the fan, cooling the cooling plate and exhausting it into the wear.

In addition, the mounting holes are located approximately directly below the user's left and right arms, so even when working while sitting in the driver's seat, such as when driving a forklift or tractor, the fan unit will not come into contact with the driver's seat of the forklift or tractor, making it convenient to use.

The fan unit is connected by a connection cable and has a controller that supplies power to the fan unit. The controller has a control unit that switches between multiple voltages to control the capacity of the battery, fan cooling unit, and Peltier cooling unit. The controller is configured to supply power of the same voltage to the fan cooling unit and Peltier cooling unit. This makes it possible to synchronize the cooling by the fan cooling unit and the cooling by the Peltier cooling unit and control their capacities, while also simplifying the wiring from the power supply unit.

The fan device also has a temperature sensor and is configured to stop cooling the Peltier cooling section when the cooling plate or the outside air temperature drops below a specified temperature, resulting in a fan device that is even less likely to cause frostbite.

Here, each of the fan devices 2, 2 may be equipped with a power source such as a battery so that each can operate independently without the controller C, or the control unit and power supply unit may be separated and configured separately.

Next, the configuration of the fan unit 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 .
The intake guard portion 3 has an intake hole 32 covered with a net-like intake guard 31 that bulges out slightly toward the intake side, and an intake flange portion 33 is formed on the outer periphery of the intake hole 32. An intake cylinder portion 34 is provided on the exhaust side of the intake guard portion 3, and a male thread portion 35 is formed on the outer periphery of the intake cylinder portion 34.

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 which bulges out laterally from the cylindrical main body portion 5.
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.

Fig. 4 is a cross-sectional view of the fan device 2 attached to the garment 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 unit 2 and the fan unit main body 4 will be described in detail below with reference to FIGS.

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

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.

As shown in Figures 4 and 5, the exhaust guard section 6 has an exhaust hole 62 covered by an exhaust guard 61 (exhaust guard) that bulges out towards the exhaust side, and a disk-shaped Peltier holder 64 with a square Peltier holder hole 63 in the center is formed at the top of the exhaust guard 61. An exhaust tube section 65 is provided on the intake side of the exhaust guard section 6, and the exhaust side end of the exhaust tube section 65 and the Peltier holder 64 are connected by a plurality of curved exhaust guard arm sections (exhaust guard arm sections) 66 formed radially to form the exhaust guard 61.

The exhaust tube portion 65 is formed in a cylindrical shape, and a plurality of engaged portions 67 that engage with the engaging claws 56 are formed on the intake side of the exhaust tube portion 65, protruding from the exhaust tube portion 65 to the intake side. A main body control unit storage portion cover portion 68 is formed on the exhaust side end of the exhaust tube portion 65, which bulges out laterally and serves as a cover for the exhaust side of the main body control unit storage portion 59.

As shown in Figures 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 toward the exhaust side, and is configured to bulge further toward the exhaust side from the top of the exhaust guard 61 that bulges 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.

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.

As shown in FIG. 5, a plurality of curved radially shaped heat dissipation arms (heat dissipation arms) 86 are formed on the outer periphery of the heat dissipation plate 83. Here, the plurality of heat dissipation 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 dissipation plate 83 using the outside air taken in by the fan, cool the cooling plate 81 using the Peltier element 82, and exhaust the heat into the wear.

As shown in Figure 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 Figures 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.

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.

Next, we will explain how the combination of the fan device 2 and the clothing 1 for the fan device works when the fan device 2 is attached to the clothing 1 and used by a user U.

As described above, the wear 1 of this embodiment is roughly in the shape of a long-sleeved work suit, 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 user U's back, fan units 2, 2 are attached, and the outside air sucked in by the fan units 2, 2 inflates the wear 1, allowing the outside air to circulate inside the wear 1, evaporating sweat from the user U's body and 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 dissipated by the sucked in outside air, and the cooling plate 81 is cooled.

In the case of a configuration in which the cooling plate 81 is brought into direct contact with the user U's body to provide a cooling sensation, 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 human body is a large heat-generating body, 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, the temperature difference between the heat exchange plate and the body or the outside air temperature becomes smaller, and the initial cooling sensation is inconveniently gradually lost.

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 expelled to the body. Then, the cooling plate 81 moves away 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 parts of the body near the cooling plate 81. Also, the outside air is cooled and condensation forms on the cooling plate 81.

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 unit 2 moves toward the body against the force of the outside air being released to the body. Then, the sufficiently cooled cooling plate 81 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 the user U can feel a great sense of coolness.

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 the fan device 2 pushing out the air. This also separates the cooling plate 81 from the body, and the cooling plate 81 is not heated directly by the body as it is when it is in contact with the body, but is cooled by the inherent cooling power of the Peltier element. This allows the cooling plate 81 to be sufficiently cooled, and makes it possible to cool the air inside the wear, etc. Furthermore, when the user U moves his or her body, the sufficiently cooled cooling plate 81 comes into contact with the body, providing a cool or refreshing feeling. Note that 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 with continued use, the cool or refreshing feeling can be maintained.

The combination of the fan device 2 and the wear 1 for the fan device in this embodiment is used by the user U when performing work, etc., 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 while performing work, etc., even during extremely hot weather.

The wear 1 covers the upper body of the user, and is configured so that its lower end fits snugly 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 halfway 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 so that its lower end U fits snugly 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 body is moved.

The exhaust hole 62 is provided with an exhaust guard 61 to prevent fingers and other objects 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. As a result, 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.

Furthermore, 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, control their capacity, and simplify 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.

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 mounting hole of the garment 1, but this is not limited to the above. For example, as shown in Patent Document 1, it is of course possible to attach the fan device 2 to the garment 1 by inserting the cylindrical fan device 2 into the mounting hole and fitting a ring member into it.

In addition, in this embodiment, the shape of the wear 1 is roughly the shape of long-sleeved work clothes that cover the upper body of the user U, but it is not limited to this. For example, it goes without saying that the attachment holes of this embodiment may be provided on any of the various types of fan-equipped wear currently available on the market.

Furthermore, it is of course possible to provide the fan device 2 with a temperature sensor such as a thermistor, and configure it so that the cooling of the Peltier cooling unit 8 stops when the cooling plate 81 or the outside air falls 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.

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.

As shown in FIG. 6, the garment 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 using rubber or the like, and attachment holes are provided near the lower end of the garment 1, but their positions are different. In the first embodiment, the attachment holes were provided near the left and right sides of the user U's back, but in this embodiment, they are provided near the sides approximately directly below the left and right arms. Also, while the garment 1 in the first embodiment had long sleeves, in this embodiment it is sleeveless and vest-like.

The mounting hole, i.e., the fan unit 2, is located near the bottom end of the garment 1, near the sides of the user U's abdomen, 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 located slightly toward the back, it may come into contact with the driver's seat of the forklift, compressing the operator's body, or the driver's seat may prevent the intake of outside air. To alleviate this, the fan unit 2 is located approximately directly below the left and right arms.

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.

The fact that the fan device 2 is attached to a position approximately directly below the left and right arms of the user U makes it convenient not only when driving a forklift, but also when two people are riding on a motorcycle. In other words, if the fan device 2 is installed slightly toward the rear, the person behind may block the intake of air by the fan device 2.

The reason why the wear 1 is a sleeveless, vest-like garment is to accommodate tasks 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 garment 1 and working in a hot environment and raises their arms, a large amount of outside air is sucked in by the fan devices 2, 2 and expelled from the armpits. The expelled outside air then evaporates and cools the sweat coming out of the user U's armpits, providing the user U with a very cool feeling.

In any case, the combination of the fan device 2 and the wear 1 of this embodiment also allows the cool or refreshing feeling to be maintained even with continuous use.
The user U uses it when performing work or the like, and feels a greater sense of coolness when moving the body, so that it can support the user U in enjoying moving the body to work, even during extreme heat.

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

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, and the like.
