FIG. 3 is a cross-sectional view of the Peltier element unit 24 in a state where the Peltier element unit 24 is attached to the fabric of the back body 3 of the temperature-adjusting garment 1. Note that the other Peltier element units 25, 26, and 27 have similar structures, so their explanations will be omitted.

The Peltier element unit 24 is attached to an insertion hole 28 provided in the back body 3. The insertion hole 28 has a folded portion formed by folding back the fabric of the back body 3 at a constant width along its inner peripheral edge and sewing the same. Note that the folded portion may be separate from the fabric of the back body 3, and may be folded back along the inner peripheral edge of the insertion hole 28 and sewn with an annular reinforcing plate with a hole inside. .

The heat exhaust fan cover part 41 and the Peltier element mounting part 42 that constitute the Peltier element unit 24 are formed by, for example, a combination of a recess and a claw piece, with the Peltier element mounting part 42 inserted inside the heat exhaust fan cover part 41. They are fixed to each other by locking means or adhesive.

The Peltier element mounting portion 42 is formed in a cylindrical shape, and is provided with a flange 43 projecting in the shape of an annular plate in the radial direction from the outer peripheral end. Furthermore, a Peltier element 44 , a heat transfer plate 45 , and a heat sink plate 46 are attached to the Peltier element attachment portion 42 . The Peltier element 44 is provided with an electrode, and the wiring cord 20 connected to the mobile battery 23 is connected to the electrode.

The Peltier element 44 is a semiconductor element that has a Peltier effect and is made by joining an N-type semiconductor and a P-type semiconductor. By passing a direct current through the Peltier element 44, a temperature difference is generated between both sides of the Peltier element 44, so that one surface becomes low temperature and the other surface becomes high temperature. By changing the direction of the current flowing through the Peltier element 44, the heat absorbing surface and the heat generating surface are reversed, so that one surface becomes high temperature and the other surface becomes low temperature. Furthermore, the temperature can be controlled by changing the amount of heat absorbed and generated by the magnitude of the current flowing.

The heat exchanger plate 45 that is in contact with one surface of the Peltier element 44 is cooled by the Peltier element 44 . The heat transfer plate 45 is provided so that the surface opposite to the surface that contacts the Peltier element 44 contacts the wearer's body. The heat transfer plate 45 cooled by the Peltier element 44 comes into contact with the wearer's body, thereby cooling the wearer's body through the abutted cooling surface. On the other hand, heat generated on the other side of the Peltier element 44 is transferred to the heat sink 46 that is in contact with the other side of the Peltier element 44, and the heat is radiated from the side facing the heat exhaust fan. The heat exchanger plate 45 and the heat sink plate 46 are formed of metal plates such as aluminum, for example.

The heat exhaust fan cover part 41 has a cylindrical shape, and an exhaust hole 49 for exhausting heat is provided between a disc-shaped top part 47 located at the top side of the cylindrical shape and a side part that is connected to the ring body 48. ing. A cylindrical storage chamber 50 is integrally formed inside the top portion 47, and a motor M is housed within the storage chamber 50. The leading end of the rotating shaft of the motor M protrudes toward the heat sink 46 attached to the Peltier element mounting portion 42, and the leading end of a cylindrical spinner 51 is fixed to the rotating shaft. A plurality of blades 52 are provided radially protruding from the outer peripheral surface of the spinner 51, and constitute a heat exhaust fan 53. The heat exhaust fan 53 exhausts the heat released from the heat sink 46 to the outside through the exhaust hole 49. Further, the heat exhaust fan cover portion 41 has a thread groove 54 formed on its outer surface.

The ring body 48 has a threaded groove 55 formed on the inner surface, an annular piece 56 protruding in the radial direction from the outer end in an annular plate shape, and a flange 43 of the Peltier element mounting portion 42 on the annular piece 56, which faces the ring body 48. A plurality of concavo-convex strips 57 are formed on a toric surface.

Next, a procedure for attaching the Peltier element unit 24 to the temperature regulating garment 1 will be explained. First, the fastener 35 provided on the back body cover member 32 that covers the fabric of the back body 3 of the temperature-adjusting garment 1 is opened.

The Peltier element unit 24 is inserted into the insertion hole 28 provided in the back body 3 from the inside of the temperature-adjusting garment 1, and the flange 43 of the Peltier element attachment part 42 is brought into close contact with the outer periphery of the insertion hole 28. Next, the ring body 48 is brought close to the heat exhaust fan cover part 41 from the outside of the fabric of the back body 3 of the temperature-adjusting garment 1 and the inside of the back body cover member 32 through the opening of the fastener 35, and the inside of the ring body 48 is The thread groove 55 formed on the side surface and the thread groove 54 formed on the outer surface of the heat exhaust fan cover part 41 are screwed together. As a result, the inner peripheral edge of the insertion hole 28 is tightly sandwiched between the flange 43 and the annular piece 56 from both inside and outside sides. Furthermore, as the screwing operation is performed, the plurality of concavo-convex strips 57 formed on the annular piece 56 of the ring body 48 rotate and bite into the fabric located outside the insertion hole 28, so that the Peltier element unit 24 is It can be easily and tightly attached to the temperature regulating garment 1. When the Peltier element unit 24 is attached to the temperature regulating garment 1 and the wiring is completed, the back body cover member 32 is closed by closing the fastener 35. In this way, by providing the fastener 35, the installation work of the Peltier element unit 24 is facilitated by opening the fastener 35, and the wiring cord 20 does not protrude from the temperature regulating garment 1 by closing the fastener 35. Conversely, when removing the Peltier element unit 24 from the temperature regulating garment 1, it can be easily removed by rotating the ring body 48 in the opposite direction to the screwing operation, removing the ring body 48, and pulling it out from the insertion hole 28. Can be done. In this way, since the Peltier element units 24 can be easily attached and detached, the number of Peltier element units 24 to be attached can be adjusted depending on the temperature environment. In addition, although the fastener 35 is provided on the back part, it may be provided at a position along the armholes 5 and 6.

Next, a case where the temperature regulating garment 1 is worn and actually used will be described.
The wiring cord 20 extending from the mobile battery 23 stored in the pocket 17 of the temperature regulating garment 1 is connected to the Peltier element units 24, 25, 26, 27, and is connected to the mobile battery 23 side or in the middle of the wiring cord 20. Turn on the placed switch (not shown). The switch can change the temperature in three stages: LOW/MID/HIGH. The temperature of the Peltier element 44 can be changed by changing the magnitude of the current flowing through the Peltier element units 24, 25, 26, and 27 in three stages: LOW/MID/HIGH. Furthermore, by turning on the switch, the heat exhaust fans 53 provided in the Peltier element units 24, 25, 26, and 27 rotate, promoting heat radiation from the heat sink 46. The heat exhaust fan 53 may change its rotational speed according to the above-mentioned three-stage temperature switching, or may rotate at a constant speed regardless of the temperature switching. Further, a switch may be turned on for each Peltier element unit 24, 25, 26, 27, or the temperature may be changed individually.

When the temperature regulating garment 1 is worn, the heat transfer plates 45 of the Peltier device units 24 and 25 are in close contact with both sides of the nape of the wearer's neck, and the heat transfer plates 45 of the Peltier device units 26 and 27 are in close contact with both sides of the wearer's armpits. By coming into close contact with the area, the area is cooled. The above locations are locations where large arteries pass near the surface of the body, and cooling these locations is effective in regulating body temperature. Therefore, in addition to the above location, the Peltier element unit may be arranged such that the heat transfer plate 45 is in close contact with, for example, the central part of the back through which the aorta passes.

When wearing the temperature-adjusting garment 1, by combining it with an air-conditioning garment that circulates outside air into the garment, the heat dissipation effect of the Peltier element itself increases, and the body can be cooled more effectively.

In the above embodiment, a temperature regulating garment that cools the body through the heat absorption effect of the Peltier element has been described, but the present invention is not limited thereto. As mentioned above, a Peltier element is a combination of an N-type semiconductor and a P-type semiconductor, and when a direct current is passed through it, one side absorbs heat while the other side generates heat. If the direction of the current is changed, the heat-absorbing surface and the heat-generating surface are reversed. Therefore, in the embodiment described above, by changing the direction of the current applied to the Peltier element in the opposite direction, the surface of the heat transfer plate 45 of the Peltier element unit 24 that contacts the body changes from a cooling surface to a heat generating surface, which protects the body. It can be used as heating clothing. Furthermore, by providing a switching means such as a switch for switching the direction of the current applied to the Peltier element, it is possible to provide air-conditioning clothing that can cool and heat the body as needed. Furthermore, the temperature inside the clothes may be adjusted by providing a temperature sensor that detects the temperature inside the clothes and switching the direction of the current according to the temperature detected by the temperature sensor.

In the embodiment described above, the thread groove 55 formed on the inner surface of the ring body 48 and the thread groove 54 formed on the outer surface of the heat exhaust fan cover part 41 are screwed together, so that the temperature regulating garment 1 can be The inner periphery of the insertion hole 28 is arranged between the inner and outer sides by the flange 43 of the Peltier element attachment part 42 located inside the fabric of the back body 3 and the annular piece 56 of the ring body 48 located outside the fabric of the back body 3. so that it is sandwiched from both sides. In contrast, by forming a flange on the heat exhaust fan cover part 41, forming a thread groove in the Peltier element attachment part 42, and screwing the ring body 48 to the Peltier element attachment part 42, the fabric of the back body 3 The inner periphery of the insertion hole 28 may be sandwiched between the annular piece 56 of the ring body 48 located inside and the flange located outside the fabric of the back body 3 from both inside and outside.
