One end of the first remote controller 70 employs, for example, a USB Type-C female terminal, and one end of the first cable 81 and one end of the first remote controller 70 are detachable.

Figure 10 is a flowchart outlining the operation of the first remote control 70 in embodiment 1.

(S1)
When the power button 71 is pressed and held (for example, for three seconds or more), power is supplied from the battery 80 to the cooling unit 5 and the two blower fans 20, and the system starts up.
When the power button 71 is pressed again for a long time (for example, for three seconds or more), the power supply from the battery 80 to the cooling unit 5 and the two blower fans 20 is stopped.

(S2)
S2 shows the state when the power button 71 is pressed and held down to start up the system.
The first cooling lamp 73, the second cooling lamp 74, and the Peltier lamp 75 are turned on.
At this time, the power supply to the two blower fans (cooling fans) 20 is at the maximum "high" level, and the power supply to the cooling unit (Peltier element) 5 is also at the maximum "high" level.

(S3)
When the power button 71 is pressed once, the first cooling lamp 73 goes out, and the second cooling lamp 74 and the Peltier lamp 75 go on.
At this time, the power supply to the two blower fans 20 is at the intermediate "medium" level, and the power supply to the cooling unit 5 is also at the intermediate "medium" level.
In the case of S3, the fluctuation mode is established.
The fluctuation mode is a mode in which an operation in which power is supplied to the cooling unit 5 and the two blower fans 20 for a certain predetermined time and an operation in which power supply to the cooling unit 5 and the two blower fans 20 is stopped for a certain predetermined time are repeated, thereby saving power from the battery 80.

(S4)
When the power button 71 is pressed again, the first cooling lamp 73 lights up, the second cooling lamp 74 goes out, and the Peltier lamp 75 lights up.
At this time, the power supply to the two blower fans 20 is at the minimum "weak" level, and the power supply to the cooling unit 5 is also at the minimum "weak" level.

(S5)
When the power button 71 is pressed again, the first cooling lamp 73 goes out, the second cooling lamp 74 goes out, and the Peltier lamp 75 goes on.
At this time, the power supply to the two blower fans 20 is stopped, the rotation of the two blower fans 20 is stopped, and the power supply to the cooling unit 5 is set to the maximum "high" level.

Pressing the power button 71 again will return to state S2.

The Peltier button 72 will now be explained. The Peltier button 72 operates in S2, S3, and S4.

When the Peltier button 72 is pressed, the Peltier lamp 75 goes out and the power supply to the cooling unit 5 is stopped.
At this time, each time the power button 71 is pressed, the power supply to the two blower fans 20 can be changed between "strong (S2),""medium(S3)," and "weak (S4)."

When the Peltier button 72 is pressed again, the Peltier lamp lights up and power is supplied to the cooling unit 5 at S2, S3, and S4. As described above, the power supply to the cooling unit 5 and the power supply to the two blower fans change in tandem between "strong (S2)," "medium (S3)," and "weak (S4)."

In Figure 10, the strength of the power supply to the cooling fan and Peltier element is switched between three levels: strong, medium, and weak, but it may also be switched between two levels: strong and weak.

According to the above aspect, the power of the cooling unit and the power of the blower fan can be linked and controlled by the control device.

(Abnormality detection)
The control device 70 includes a central processing unit (CPU), a storage device such as a memory, a first current detection device, a second current detection device, and the like (not shown).
The memory device stores a threshold value (IT1) for the motor current of the two blower fans 20 (simply referred to as blower fan current) and a threshold value (IT2) for the motor current of the exhaust fan 7 (simply referred to as exhaust fan current).
The main operations described below are executed by the control device 70.

First, the blower fan 20 will be described.
The control device 70 has a first current detection device that detects the current of the blower fan.
The first current detection device performs analog-to-digital conversion (A/D conversion) on the blower fan current and sends the current blower fan current value (I1) to the CPU.

The CPU compares the blower fan current threshold (IT1) stored in the storage device with the current blower fan current value (I1), and if the current blower fan current value (I1) exceeds the blower fan current threshold (IT1) (I1>IT1), it stops supplying power to the blower fan 20.
The state where I1>IT1 is a state where an overcurrent flows in one or both of the motors of the two blower fans 20.
Then, at least one of the first cooling lamp 73, the second cooling lamp 74, and the Peltier lamp 75, or all of the lamps, are flashed to notify the user of the abnormality (error mode).

The user checks whether or not a foreign object such as a nail is caught between the two blower fans 20, and if a foreign object is caught, removes it.
To cancel the error mode, the user unplugs one end (connection part) of the first cable 81 from the battery 80 or the first remote control (control device) 70, and then plugs it back in to return it to its original state, thereby canceling the error mode.

In this way, even if a foreign object becomes caught in the blower fan 20, the blower fan 20 motor can be prevented from malfunctioning.

Note that although an abnormality detection means for the blower fan 20 is provided, an embodiment may be adopted in which no abnormality detection means for the blower fan 20 is provided.

Next, the heat exhaust fan 7 will be described.
The control device 70 has a second current detection device that detects the heat exhaust fan current.
The second current detection device performs analog-to-digital conversion (A/D conversion) on the heat exhaust fan current and sends the current value (I2) of the heat exhaust fan current to the CPU.

The CPU compares the heat exhaust fan threshold (IT2) stored in the storage device with the current heat exhaust fan value (I2), and if the current heat exhaust fan value (I2) exceeds the heat exhaust fan threshold (IT2) (I2>IT2), it stops supplying power to the heat exhaust fan 7.
When I2>IT2, an overcurrent flows through the motor of the heat exhaust fan 7.
Then, at least one of the first cooling lamp 73, the second cooling lamp 74, and the Peltier lamp 75, or all of the lamps, are flashed to notify the user of the abnormality (error mode).

The user checks whether or not a foreign object such as a nail is caught in the heat exhaust fan 7, and if a foreign object is caught, removes it.
To cancel the error mode, the user unplugs one end (connection part) of the first cable 81 from the battery 80 or the first remote control (control device) 70, and then plugs it back in to return it to its original state, thereby canceling the error mode.

In this way, even if a foreign object gets caught in the heat exhaust fan 7, the motor of the heat exhaust fan 7 can be prevented from breaking down.

The first current detection device and the second current detection device may be provided separately at any location on the garment 1 other than the control device 70 .
Although A/D conversion is performed by the first current detection device and the second current detection device, the control device 70 may be provided with a separate A/D conversion device to perform A/D conversion.

When the garment 100 and the full harness-type fall protection device 94 are worn together, the lanyard 95 or the connecting belt 98 can be removed from the body through the opening 91. At this time, the two cooling units 5 are positioned on the left and right to avoid the ears 90, so they do not come into contact with the lanyard 95 or the connecting belt 98. In other words, the ears 90 and the opening 91 are positioned between the two cooling units 5.
According to the above aspect, by providing an opening between the two cooling units, the lanyard or connecting belt of the full harness type fall protection device can be removed from the clothing.

(Embodiment 3)

FIG. 16 is a schematic rear view of the garment 101 according to the third embodiment.
As shown in Figure 16, the center of the blower fan 20 has been moved from the position of the lower back as in embodiment 1 to one of the following positions: an upper position of the lower back, a position between the lower back and the back, or a lower position of the back.
Specifically, based on the state in which the garment 101 is worn by a person, the position of the lower end 22 of the blower fan support 21 is moved 3 cm to 7 cm, preferably 4 cm to 6 cm, above the lower waist position.
According to the above-described embodiment, the blower fan 20 is located close to the cooling unit 5 (heat exhaust fan 7), so that more air taken in from the blower fan 20 can be sent to the heat exhaust fan 7. As a result, the exhaust capacity of the heat exhaust fan 7 can be improved, and the cooling unit 5 can cool the body more effectively.

(Embodiment 4)
The fourth embodiment differs from the first to third embodiments in that the blower fan 20 is provided on the side of the body. The configuration other than the above is the same as that of the first embodiment.
FIG. 17A is a schematic perspective view of the garment 102 according to the fourth embodiment, and FIG. 17B is a schematic side view of the garment 102 according to the fourth embodiment.
Each of the garments 1, 100, and 101 of the first to third embodiments has two blower fans 20 arranged in the lower back area.
In this case, when a driver wearing the garments 1, 100, 101 drives a vehicle such as a truck, bus, or taxi, the two blower fans 20 come into contact with the car seats. As a result, the two blower fans 20 hit the driver's back, causing discomfort to the driver. Furthermore, because the intake ports of the two blower fans 20 are blocked by the seats, the amount of air drawn in by the two blower fans 20 decreases, resulting in a new problem of a decrease in the cooling capacity of the cooling unit 5.

Therefore, in the fourth embodiment, as shown in Figures 17A and 17B, two blower fans 20 are arranged on both sides of the body, and the two blower fans 20 are not in contact with the car seat.
In FIG. 17B, an armhole 110 is illustrated schematically.
As shown in FIG. 17B, the blower fans 20 are placed on both sides of the body, at the waist.
According to the above-described embodiment, the two blower fans 20 are arranged on both sides of the driver's body so that the two blower fans 20 do not hit the driver's back, thereby preventing the driver from feeling uncomfortable. Furthermore, since the intake ports of the two blower fans 20 are not blocked by chairs, a decrease in the cooling capacity of the cooling unit 5 can be prevented.

(Embodiment 5)
The fifth embodiment differs from the first to fourth embodiments in that an air-blocking fabric 112 with reduced breathability is used for the front fabric 2 and the back fabric 3 of the garment 103. The configuration other than that described above is the same as that of the first embodiment.
FIG. 18A is a schematic rear view of the garment 103 in the fifth embodiment, and FIG. 18B is a schematic side view of the garment 103 in the fifth embodiment.

As shown in Figures 18A and 18B, the solid arrows represent the airflow caused by the blower fan 20 and the heat exhaust fan 7 of the cooling unit 5. The dashed-dotted lines represent the airflow cooled by the metal plate 12 of the cooling unit 5.

First, the air flow caused by the blower fan 20 and the heat exhaust fan 7 of the cooling unit 5 will be described.
The outside air of the clothes 103 is taken into the inside of the clothes 103 by the blower fan 20.
The taken-in air is discharged to the outside of the garment 103 mainly via the following three routes.
(1) The air is drawn from the lower back to the back and is then exhausted from the back to the outside of the clothing 103 by the exhaust fan 7 .
(2) The air is discharged from the lower back to the back, from the back to the neck, and from the neck to the outside of the clothing 103.
(3) The air is discharged from the waist to the abdomen, from the abdomen to the chest, from the chest to the neck, and from the neck to the outside of the clothing 103.

In the fifth embodiment, the air-blocking fabric 112 is used for all or part of the front fabric 2 and/or for all or part of the back fabric 3. This allows the air that hits the front fabric 2 and/or the back fabric 3 to be repelled. The cooling unit 5 is in contact with the body, and the garment 103 in contact with the cooling unit 5 is in close proximity to the body.
The areas of the clothing 103 that are not in contact with the cooling unit 5 are separated from the body and inflated, leaving a space between them and the body (FIG. 18B).
Here, the meaning of the entire front fabric 2 and the entire back fabric 3 will be explained.
The entire front fabric 2 and the entire back fabric 3 refer to the main parts of the front fabric 2 and the back fabric 3, excluding auxiliary parts such as auxiliary lines reinforcing the edges of the garment 103, the surfaces of the pockets, and the edges of the pockets.

Next, the flow of air cooled by the metal plate 12 of the cooling unit 5 (dotted chain line) will be described.
18A and 18B , the metal plate 12 of the cooling unit 5 cools the air around the metal plate 12. The metal plate 12 cools the air taken into the interior of the garment 103 by the blower fan 20 in the space on the back on the lining fabric 3 side of the garment 103. The cooled air moves to the spaces on the chest and abdomen on the front fabric 2 side of the garment 103. The air cooled on the front fabric 2 side and the lining fabric 3 side of the garment 103 is discharged to the outside from the neck.
In addition, a part of the air cooled on the front fabric 2 side and the back fabric 3 side of the garment 103 is discharged to the outside of the garment 103 by the heat exhaust fan 7 .

Next, the air-blocking fabric 112 of the garment 103 will be described.
The air-blocking fabric 112 of the garment 103 is a woven fabric.
The air-blocking fabric 112 is a fabric that is windproof or has reduced breathability. In other words, the air-blocking fabric 112 is a fabric that makes it difficult for air outside the garment 103 to penetrate inside and makes it difficult for air inside the garment 103 to escape to the outside.
In other words, the density of the air blocking fabric 112 is greater than the density of ordinary clothing.

Since there is a correlation between the density of a fabric and the total number of weft threads per inch and the total number of warp threads per inch (hereinafter simply referred to as the total number of weft and warp threads), the density of a fabric can be expressed as the total number of weft and warp threads.

Generally, fabrics that do not have windproof properties or fabrics that do not have restricted breathability have a warp thread count of 110 per inch, a weft thread count of 70 to 80 per inch, and a total of 180 to 190 weft and warp thread counts.
On the other hand, the garment 103 has a warp thread count of, for example, 90 threads per inch, a weft thread count of, for example, 145 threads per inch, and a total of 235 threads of weft and warp threads.
Therefore, the total number of weft and warp threads of the garment 103 is preferably 200 or more and 300 or less, and more preferably 200 or more and 250 or less.

According to the above aspect, by using the breathable fabric 112 in the garment 103, the entire body can be cooled by the air cooled by the metal plate 12. It can also cool the neck area, which is sensitive to cold.

(Variation 1)
FIG. 18C is a schematic side view of the garment 104 according to the first modification of the fifth embodiment.
18C , the garment 104 of the first modification has a processed layer 113 provided on the inside of the air blocking fabric 112 of the garment 103 of the fifth embodiment. The processed layer 113 may also be provided on the outside of the air blocking fabric 112.
The processed layer 113 is a layer that is processed on the inside or outside of the air blocking fabric 112 to increase the density of the air blocking fabric 112 .
Specific processing methods include sire processing (calendering) and titanium processing (titanium coating).
Titanium processing is particularly preferable because it reflects and blocks infrared and ultraviolet rays, thereby preventing the temperature inside the clothing 104 from rising.
