[0047] According to the above aspect, the blower fan can be easily attached to and detached from the clothing. Furthermore, according to the above aspect, the detachable unit and the blower fan can be easily detached from the clothes, so that the clothes can be washed.

[0048] (Power Control) FIG. 9 is a schematic diagram showing the wiring relationship of the garment 1 in the first embodiment. With the first remote control (control device) 70 at the center, the first remote control 70 and the battery 80 are connected by a first cable 81, the first remote control 70 and the cooling unit 5 are connected by a second cable 82, the first remote control 70 and the right-side blower fan 20 are connected by a fifth cable 85, and the first remote control 70 and the left-side blower fan 20 are connected by a fourth cable 84. The fourth cable 84 and the fifth cable 85 branch off from the middle of the third cable 83. 3, a cable stopper 64 for stopping the second cable 82 is provided on the back fabric 3. Also, an inner pocket 65 for accommodating the first remote control 70 and the battery 80 is provided.

[0049] The first remote control 70 has a power button 71 , a Peltier button 72 , a first cooling lamp 73 , a second cooling lamp 74 , and a Peltier lamp 75 . The battery 80 supplies power and is preferably a mobile battery. The first cable 81 is preferably a USB cable that has good connectivity with a mobile battery.

[0050] One end of the first cable 81 facing the first remote control 70 employs, for example, a USB Type-C male terminal, and the other end of the first cable 81 employs, for example, a USB Type-A male terminal. One end of the first remote control 70 employs, for example, a female USB Type-C terminal, and one end of the first cable 81 and one end of the first remote control 70 are detachable from each other.

[0051] FIG. 10 is a schematic flowchart showing the operation of the first remote control 70 in the first embodiment.

[0052] (S1) When the power button 71 is pressed and held (eg, 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.

[0053] (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 maximum "high", and the power supply to the cooling unit (Peltier element) 5 is also at maximum "high".

[0054] (S3) When the power button 71 is pressed once, the first cooling lamp 73 is turned off, and the second cooling lamp 74 and the Peltier lamp 75 are turned on. At this time, the power supply to the two blower fans 20 is at the intermediate level of "medium", and the power supply to the cooling unit 5 is also at the intermediate level of "medium". In the case of S3, this is a fluctuation mode. 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. This allows the power of the battery 80 to be saved.

[0055] (S4) When the power button 71 is pressed again, the first cooling lamp 73 turns on, the second cooling lamp 74 turns off, and the Peltier lamp 75 turns on. At this time, the power supply to the two blower fans 20 is at the minimum "weak", and the power supply to the cooling unit 5 is also at the minimum "weak".

[0056] (S5) When the power button 71 is pressed again, the first cooling lamp 73 is turned off, the second cooling lamp 74 is turned off, and the Peltier lamp 75 is turned 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".

[0057] Pressing the power button 71 again returns to the S2 state.

[0058] The following describes the Peltier button 72. The Peltier button 72 operates in S2, S3, and S4 states.

[0059] When the Peltier button 72 is pressed, the Peltier lamp 75 goes out and the power supply to the cooling unit 5 stops. At this time, each time the power button 71 is pressed, the power supply to the two blower fans 20 can be changed between "high (S2)", "medium (S3)" and "low (S4)".

[0060] When the Peltier button 72 is pressed again, in S2, S3, and S4, the Peltier lamp lights up and power is supplied to the cooling unit 5. In 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 conjunction with each other to "high (S2)", "medium (S3)", and "low (S4)".

[0061] In FIG. 10, the strength of the power supply to the cooling fan and the Peltier element is switched between three levels, strong, medium, and weak, but it may be switched between two levels, strong and weak.

[0062] 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.

[0063] (Anomaly 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 storage device stores a threshold value (IT1) of the motor currents of the two blower fans 20 (simply referred to as blower fan currents) and a threshold value (IT2) of the motor current of the heat exhaust fan 7 (simply referred to as heat exhaust fan current). The main operations of the following operations are executed by the control device 70.

[0064] First, the blower fan 20 will be described. The control device 70 has a first current detection device that detects the blower fan current. 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.

[0065] 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), stops the power supply to the blower fan 20. The state where I1>IT1 is a state where an overcurrent flows through 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 above lamps, are caused to flash to notify the user of the abnormality (error mode).

[0066] 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 the foreign object. To cancel the error mode, the user must unplug one end (connection part) of the first cable 81 from the battery 80 or the first remote control (control device) 70, and then plug it back in to its original state, thereby canceling the error mode.

[0067] In this way, even if a foreign object gets caught in the blower fan 20, the motor of the blower fan 20 can be prevented from breaking down.

[0068] Although the abnormality detection means for the blower fan 20 is provided, the abnormality detection means for the blower fan 20 may not be provided.

[0069] 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.

[0070] 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 the power supply 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 above lamps, are caused to flash to notify the user of the abnormality (error mode).

[0071] 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 must unplug one end (connection part) of the first cable 81 from the battery 80 or the first remote control (control device) 70, and then plug it back in to its original state, thereby canceling the error mode.

[0072] 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.

[0073] 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. In addition, A / D conversion was performed by the first current detection device and the second current detection device, but the control device 70 Alternatively, a separate A / D conversion device may be provided to perform A / D conversion.

[0076] 11, a person is wearing a full harness type fall protection device 94. The full harness type fall protection device 94 has a lanyard 95 equipped with a hook 96 and a shock absorber 97, and a connecting belt 98.

[0077] As shown in FIG. 12, the back fabric 3 has two cooling units 5, ears 90, and an opening 91. The opening 91 is disposed on a center line 92 of the back fabric 3. The ear portion 90 is a cover that covers the opening 91, and is disposed on the center line 92 of the back fabric 3.

[0078] When the garment 100 and the full harness type fall protection device 94 are worn one on top of the other, the lanyard 95 or the connecting belt 98 can be ejected from the body through the opening 91. At that time, the two cooling units 5 are arranged on the left and right to avoid the ears 90, so that 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 arranged between the two cooling units 5. According to the above embodiment, 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.

[0079] (Embodiment 3) The third embodiment differs from the first embodiment in that (1) one end of a sixth cable 86 (described later) and one end of a second remote control 77 (described later) are joined together and cannot be separated, and (2) the center of the blower fan 20 is moved from the waist to a position between the waist and the back. The configuration other than the above-mentioned two components is the same as that of the first embodiment. FIG. 13 is a schematic diagram showing the wiring relationship of clothing 101 in embodiment 3, FIG. 14 is a schematic oblique view of second remote control 77 in embodiment 3, FIG. 15A is a schematic plan view of second remote control 77 in embodiment 3, and FIG. 15B is a schematic front view of second remote control 77 in embodiment 3.

[0080] First, a configuration in which one end of the sixth cable 86 and one end of the second remote control 77 are joined together and cannot be separated will be described in the third embodiment. As shown in FIGS. 13, 14, 15A and 15B, a first remote control connector 88 is provided at one end of second remote control 77 of the third embodiment, and a second remote control connector 89 is provided at the other end of second remote control 77.

[0081] The first remote control connector 88 and one end of the sixth cable 86 are physically connected, and one end of the sixth cable 86 cannot be removed from the first remote control connector 88. In addition, the first remote control connector 88 is fixed to the second remote control 77 so that it cannot be removed.

[0082] At the other end of the second remote control 77, one end of the second cable 82 and one end of the third cable 83 are physically connected to a second remote control connector 89. The second remote control connector 89 is also fixed so that it cannot be removed from the second remote control 77.

[0083] The sixth cable 86 is a cable that transmits power from the battery 80 (FIG. 9) to the second remote control 77, and the other end of the sixth cable 86 is provided with a cable terminal 87. The cable terminal 87 is preferably a male terminal of, for example, USB Type-A, which can be physically and electrically connected to the battery 80 .

[0084] According to the above aspect, the second remote control 77 and the first remote control connector 88 (one end of the sixth cable 86) are fixed so as not to be disconnected as in the first embodiment, so that it is possible to prevent the first remote control connector 88 (one end of the sixth cable 86) from being damaged. In addition, the cable terminal 87 is a USB Type-A male terminal, so it is possible to connect it to a mobile battery that is widely used on the market.

[0085] Next, a configuration in which the center of the blower fan 20 is moved from the position of the lower back to a position between the lower back and the back will be described. FIG. 16 is a schematic rear view of the garment 101 in the third embodiment. As shown in FIG. 16, the center of the blower fan 20 is moved from the waist position in the first embodiment to one of the following positions: an upper waist position, a position between the waist and the back, or a lower back position. Specifically, based on the state in which clothing 101 is worn by a person, the position of lower end 22 of 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 embodiment, since the blower fan 20 is close to the cooling unit 5 (heat exhaust fan 7), it is possible to send a large amount of air drawn from the blower fan 20 to the heat exhaust fan 7. As a result, it is possible to improve the exhaust capacity of the heat exhaust fan 7, so that the cooling unit 5 can cool the body more effectively.

[0086] (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 in the fourth embodiment, and FIG. 17B is a schematic side view of the garment 102 in 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 wears the garments 1, 100, 101 and drives a vehicle such as a truck, a bus, or a taxi, the two blower fans 20 come into contact with the seat of the vehicle. As a result, the two blower fans 20 hit the driver's back, causing a new problem that the driver feels uncomfortable. In addition, the intake ports of the two blower fans 20 are blocked by the seat, reducing the amount of air drawn in by the two blower fans 20, causing a new problem that the cooling capacity of the cooling unit 5 is reduced.

[0087] Therefore, in the fourth embodiment, as shown in Figs. 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 diagrammatically. As shown in FIG. 17B, the blower fans 20 are disposed on both sides of the body, at the waist. According to the above embodiment, the two blower fans 20 are arranged on both sides of the body so that the two blower fans 20 do not hit the driver's back, which prevents the driver from feeling uncomfortable. In addition, the intake ports of the two blower fans 20 are not blocked by chairs, which prevents the cooling capacity of the cooling unit 5 from decreasing.

[0088] (Embodiment 5) The fifth embodiment differs from the first to fourth embodiments in that an air-blocking fabric 112 with reduced air permeability 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.

[0089] 18A and 18B, the solid arrows represent the flow of air caused by the blower fan 20 and the heat exhaust fan 7 of the cooling unit 5. The dashed and dotted lines represent the flow of air cooled by the metal plate 12 of the cooling unit 5.

[0090] First, the airflow 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 garment 103 is taken into the inside of the garment 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 toward the back and then exhausted from the back to the outside of the clothing 103 by the heat 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 garment 103. (3) The air is discharged from the lower back 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.

[0091] In the fifth embodiment, the air-blocking fabric 112 is used for a part or all of the front fabric 2 and / or a part or all of the back fabric 3. This allows air to be repelled when it hits the front fabric 2 and / or the back fabric 3. 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 portion of the garment 103 that is not in contact with the cooling unit 5 is separated from the body and inflated, leaving a space between the garment 103 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.

[0092] Next, the flow of air (dashed line) cooled by metal plate 12 of cooling unit 5 will be described. As shown by the dashed dotted lines in Figures 18A and 18B, metal plate 12 of cooling unit 5 cools the air around metal plate 12. Metal plate 12 cools the air taken into the interior of garment 103 by blower fan 20 in the space on the back on the side of the lining fabric 3 of garment 103. The cooled air moves to the space on the chest and abdomen on the side of the front fabric 2 of garment 103. The air cooled on the front fabric 2 side and the lining fabric 3 side of garment 103 is discharged to the outside from the neck area. Further, a part of the air cooled on the front fabric 2 side and the back fabric 3 side of the garment 103 is exhausted to the outside of the garment 103 by the heat exhaust fan 7.

[0093] Next, the air-blocking fabric 112 of the garment 103 will be described. The air barrier fabric 112 of the garment 103 is a woven fabric. The airflow blocking fabric 112 is a fabric that is windproof or has reduced breathability. In other words, the airflow blocking fabric 112 is a fabric that makes it difficult for air outside the garment 103 to penetrate to the inside, and makes it difficult for air inside the garment 103 to be expelled to the outside. In other words, the density of the air blocking fabric 112 is greater than that of normal clothing.

[0094] 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 referred to simply as the total number of weft threads and warp threads), the density of a fabric can be expressed as the total number of weft threads and warp threads.

[0095] A typical fabric that is not windproof or has unrestricted breathability has 110 warp threads per inch, between 70 and 80 weft threads per inch, and a combined total of 180 to 190 weft and warp threads per inch. 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.

[0096] According to the above embodiment, by using the breathable blocking fabric 112 for the garment 103, the entire body can be cooled by the air cooled by the metal plate 12. In addition, the neck area, which is easily sensitive to cold, can be cooled.

[0097] (Variation 1) FIG. 18C is a schematic side view of the garment 104 of 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 is a layer on the inside or outside of the air blocking fabric 112 that is processed to increase the density of the air blocking fabric 112 . Specific processing methods include calendar processing and titanium processing (titanium coating). In particular, titanium processing is preferable because it reflects and blocks infrared and ultraviolet rays, thereby preventing the temperature inside the clothing 104 from rising.
