Description

The present invention relates to temperature regulating garments.

For example, there are thermoregulatory clothes worn by workers who work outdoors in the hot sun or in high-temperature environments to cool their bodies and regulate their body temperature.

For example, Patent Literature 1 discloses that a detachable storage member is provided for clothes, and the body is cooled by wearing the clothes containing a cooling agent in the storage member. Further, Patent Document 2 discloses a garment provided with an air intake port and a fan to cool the body by circulating outside air into the garment in parallel with the body. Further, in Patent Document 3, a flexible tube for circulating a liquid at a predetermined temperature that is lower or higher than the human body is arranged on the inner surface of the clothes in a meandering shape as a whole, and is connected through the tube. It is disclosed to deliver the liquid at the predetermined temperature from a cooled or warmed device.

JP-A-2003-55811 Japanese Patent No. 4329118 JP 2017-57518 A

However, when cooling the body with clothes provided with a cooling agent, it is difficult to adjust the temperature, and the cooling effect of the cooling agent decreases over time. Therefore, the wearer of the clothes needs to replace the cooling agent each time the cooling effect of the cooling agent decreases, which makes it difficult to wear the clothes continuously for a long time and takes time and effort to replace the cooling agent. In addition, when an air intake port and a fan are provided in clothes to circulate outside air into the inside of the clothes, if the outside air is hot, a sufficient cooling effect on the body cannot be obtained. Furthermore, since outside air is circulated inside the clothes, the clothes are inflated, and there is a problem that the mobility and workability of the worker wearing the clothes are lowered. In addition, if a tube for circulating a liquid of a predetermined temperature is arranged on the inner surface of the garment in a meandering manner as a whole, the structure of the garment becomes complicated. Furthermore, the weight of the tube and the liquid increases the weight of the entire garment, and the thickness of the tube increases the thickness of the entire garment, resulting in reduced mobility and workability of the worker wearing the garment.

SUMMARY OF THE INVENTION It is an object of the present invention to provide temperature-regulating clothing that can regulate body temperature for a long period of time without interfering with the mobility and workability of the worker wearing the clothing. and

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 control garment 1. As shown in FIG. Since the other Peltier element units 25, 26, and 27 have the same structure, their description is 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 and sewing the fabric of the back body 3 along the inner peripheral edge thereof. The folded portion may be a separate piece from the fabric of the back body 3, or may be folded back along the inner peripheral edge of the insertion hole 28 and sewn while holding an annular reinforcing plate with a hole inside. .

The exhaust heat fan cover portion 41 and the Peltier element mounting portion 42 that constitute the Peltier element unit 24 are arranged in a state in which the Peltier element mounting portion 42 is inserted inside the exhaust heat fan cover portion 41, for example, a combination of a concave portion and a claw piece. are secured to each other by means of locking means or by gluing.

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

The Peltier element 44 is a semiconductor element that has a Peltier effect by joining an N-type semiconductor and a P-type semiconductor. By applying a direct current to the Peltier element 44, a temperature difference occurs between the two surfaces of the Peltier element 44, 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, with one surface having a high temperature and the other surface having a low temperature. Also, the temperature can be controlled by changing the amount of heat absorption and heat generation depending on the magnitude of the current.

The heat transfer plate 45 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 in contact with the Peltier element 44 is in contact with the wearer's body. The heat transfer plate 45 cooled by the Peltier element 44 cools the wearer's body through the contacted cooling surface by coming into contact with the wearer's body. On the other hand, the heat dissipation plate 46 in contact with the other surface of the Peltier element 44 conducts the heat generated on the other surface of the Peltier element 44 and radiates heat from the surface facing the exhaust heat fan. The heat transfer plate 45 and the heat radiation plate 46 are made of a metal plate such as aluminum.

The exhaust heat fan cover part 41 has a cylindrical shape, and an exhaust hole 49 for exhausting heat is provided between a disk-shaped top part 47 located on the top side of the cylindrical shape and a side part coupled to the ring body 48 . ing. A cylindrical storage chamber 50 is integrally formed inside the top portion 47 , and the motor M is housed in the storage chamber 50 . The tip of the rotating shaft of the motor M protrudes toward the radiator plate 46 attached to the Peltier element attachment portion 42, and the tip of a cylindrical spinner 51 is fixed to the rotating shaft. A plurality of blades 52 are radially protruded from the outer peripheral surface of the spinner 51 to form a heat exhaust fan 53 . The exhaust heat fan 53 exhausts the heat emitted from the radiator plate 46 to the outside through the exhaust holes 49 . Further, a screw groove 54 is formed on the outer surface of the exhaust heat fan cover portion 41 .

The ring body 48 has a thread groove 55 formed on the inner surface, an annular piece 56 projecting radially from the outer end in the shape of an annular plate, and the annular piece 56 facing the flange 43 of the Peltier element mounting portion 42 . and a plurality of ridges and ridges 57 formed on the annular surface.

Next, a procedure for attaching the Peltier element unit 24 to the temperature control garment 1 will be described. First, the fastener 35 provided on the back body cover member 32 covering the fabric of the back body 3 of the temperature control garment 1 is opened.

The Peltier element unit 24 is inserted from the inside of the temperature control garment 1 into the insertion hole 28 provided in the back body 3, and the flange 43 of the Peltier element mounting portion 42 is brought into close contact with the outer peripheral edge of the insertion hole 28. - 特許庁Next, the ring body 48 is brought close to the exhaust heat fan cover part 41 from the outside of the fabric of the back body 3 of the temperature control garment 1 and inside the back body cover member 32 from the opening of the fastener 35, and the inside of the ring body 48 is The screw groove 55 formed on the side surface and the screw groove 54 formed on the outer surface of the exhaust heat fan cover portion 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 the inner and outer sides. Moreover, along with this screwing operation, the plurality of uneven streaks 57 formed on the annular piece 56 of the ring body 48 bites into the cloth positioned outside the insertion hole 28 while rotating, so that the Peltier element unit 24 is held in place. It can be easily and tightly attached to the temperature regulating garment 1 . After the Peltier element unit 24 is attached to the temperature control garment 1 and the wiring is completed, the back body cover member 32 is closed by closing the fastener 35. - 特許庁By providing the fastener 35 in this way, 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 control garment 1 by closing the fastener 35.例文帳に追加Conversely, when removing the Peltier element unit 24 from the temperature control garment 1, the ring body 48 can be easily removed by rotating it in the direction opposite to the screwing operation, removing the ring body 48, and pulling it out from the insertion hole 28. can be done. Since the Peltier element units 24 can be easily attached and detached in this manner, the number of Peltier element units 24 to be attached can be adjusted according to the temperature environment. Although the fasteners 35 are provided on the back portion, they may be provided along the armholes 5 and 6 .

Next, a case where the temperature control garment 1 is worn and actually used will be described.
A wiring cord 20 extending from a mobile battery 23 housed in a pocket portion 17 of the temperature control garment 1 is connected to Peltier element units 24, 25, 26, and 27, and is connected to the mobile battery 23 side or in the middle of the wiring cord 20. The arranged switch (not shown) is turned on. The switch can switch the temperature in three stages of 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 of LOW/MID/HIGH. Also, by turning on the switch, the exhaust heat fans 53 provided in the Peltier element units 24 , 25 , 26 , 27 rotate to promote heat radiation from the radiator plate 46 . The exhaust heat fan 53 may change its rotation speed according to the switching of the temperature in the above three stages, or may rotate at a constant speed regardless of the switching of the temperature. Also, each of the Peltier element units 24, 25, 26 and 27 may be switched on, or the temperature may be switched individually.

When the temperature control garment 1 is worn, the heat transfer plates 45 of the Peltier element units 24 and 25 are in close contact with both sides of the neck of the wearer, and the heat transfer plates 45 of the Peltier element units 26 and 27 are positioned under both armpits of the wearer. By being in close contact with the part, the part 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, the Peltier element unit may be arranged so that the heat transfer plate 45 is in close contact with, for example, the center portion of the back through which the aorta passes, other than the above locations.

When the temperature control garment 1 is worn, combining it with an air-conditioning garment that circulates the outside air inside the garment enhances the heat dissipation effect of the Peltier device itself, so that the body can be cooled more effectively.

In the above embodiment, the temperature control garment that cools the body by the heat absorbing action of the Peltier element has been described, but the present invention is not limited to this. As mentioned above, a Peltier element is a junction of an N-type semiconductor and a P-type semiconductor, and when a direct current is passed through it, one side absorbs heat and the other side generates heat. If the direction of the current is changed, the side that absorbs heat and the side that generates heat are reversed. Therefore, in the above-described embodiment, by reversing the direction of the current applied to the Peltier element, 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, thereby heating the body. It can be used as a heating garment to warm. Furthermore, by providing switching means such as a changeover switch for switching the direction of the current applied to the Peltier device, it is possible to provide cooling and heating clothing capable of cooling and heating the body as required. Furthermore, a temperature sensor for detecting the temperature inside the clothes may be provided, and the temperature inside the clothes may be adjusted by switching the direction of the current according to the temperature detected by the temperature sensor.

In the above embodiment, the screw groove 55 formed on the inner surface of the ring body 48 and the screw groove 54 formed on the outer surface of the exhaust heat fan cover portion 41 are screwed to each other so that the temperature control garment 1 can be adjusted. The flange 43 of the Peltier element mounting portion 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 make the inner peripheral edge of the insertion hole 28 inside and outside. It was made to be sandwiched from both sides of the On the other hand, by forming a flange in the exhaust heat fan cover portion 41, forming a screw groove in the Peltier element mounting portion 42, and screwing the ring body 48 to the Peltier element mounting portion 42, the fabric of the back body 3 is removed. The inner peripheral edge of the insertion hole 28 may be sandwiched from both the inner and outer sides by the annular piece 56 of the ring body 48 located inside and the flange located outside the fabric of the back body 3 .
