Description

The present invention relates to a heat exchange unit and clothes including the same, and more particularly to a technique for cooling or heating the body of a wearer.

BACKGROUND ART Conventionally, there is known a garment with a fan that takes in outside air into the garment by a fan attached to the garment and cools the body of the wearer (for example, Patent Document 1). However, since the fan-equipped garment only sends the outside air into the garment, it cannot be said that it is a comfortable garment because the cooling effect is low when the outside temperature is high.

In addition, conventionally, there is also known a garment which can cool or heat a body by flowing cold water or hot water through a water passage provided inside the garment (for example, Patent Document 2). However, the configuration in which cold water or hot water is flowed inside the clothes increases the weight of the clothes, so that there is a drawback in that the motion of the wearer becomes slow.

FIG. 1 is a diagram showing the heat exchange unit 1 and its control mechanism in the present embodiment. FIG. 2 is a diagram showing the garment 100 to which the heat exchange unit 1 is attached. FIG. 3 is an exploded perspective view showing the configuration of the heat exchange unit 1. FIG. 4 is a cross-sectional view showing the configuration of the heat exchange unit 1. The heat exchange unit 1 of the present embodiment shown in these drawings is for performing heat exchange using the Peltier element 17 to cool or heat the body of the wearer of the garment 100. For example, as shown in FIG. 2A, the heat exchange unit 1 is attached to the cloth 101 of the back body of the garment 100 to cool or heat the back of the wearer's body. The heat exchange unit 1 uses the cloth 101 of the garment 100 as a partition, circulates the temperature-controlled air inside the garment 100, and discharges waste heat to the outside of the garment 100.

As shown in FIG. 3, the heat exchange unit 1 mainly includes fan guards 11 and 21, blower members 12 and 22, fans 14 and 24, heat transfer members 13 and 23, a partition plate 16, and a Peltier. The device 17 and the fixing ring 25 are provided. The heat exchange unit 1 is divided into a part that is attached to the inside of the garment 100 and a part that is attached to the outside of the garment 100 with the partition plate 16 and the fixing ring 25 sandwiched between the cloth 101 of the garment 100. Inside the garment 100, a fan guard (first fan guard) 11, a blower member (first blower member) 12, a heat transfer member (first heat transfer member) 12, and a fan (first fan). And 14 are provided. Further, on the outside of the garment 100, a fan guard (second fan guard) 21, a blower member (second blower member) 22, a heat conduction member (second heat conduction member) 23, and a fan (second blower member). Fan) 24 is provided.

The partition plate 16 is a member that, together with the cloth 101 of the garment 100, forms a partition wall that separates the inside and the outside of the garment 100, and is configured by a substantially circular heat insulating plate. The thickness of the partition plate 16 is substantially the same as the thickness of the Peltier element 17. The partition plate 16 is formed with a hole 16a having substantially the same size as the Peltier element 17 in the center thereof, and the Peltier element 17 is accommodated and held in the hole 16a. In addition, holes 16b for attaching the fixing ring 25 are formed at a plurality of peripheral portions of the partition plate 16.

The external size of the fixing ring 25 is substantially the same as the external size of the partition plate 16, and is attached to one surface of the partition plate 16. FIG. 3 shows an example in which the fixing ring 25 is attached to the partition plate 16 from the outside of the garment 100. The open portion 25 a inside the fixing ring 25 has a diameter larger than the outer size of the heat conducting member 23. Further, holes 25b similar to the holes 16b formed in the partition plate 16 are formed at a plurality of peripheral portions of the fixing ring 25. The fixing ring 25 is arranged so that the cloth 101 of the garment 100 is sandwiched between the fixing ring 25 and the partition plate 16, and is fixed to the partition plate 16 by mounting a fixing member 26 such as a screw in the holes 25b and 16b. ..

The fixing member 26 for fixing the fixing ring 25 to the partition plate 16 is preferably a removable member. If the fixing member 26 is removable, the heat exchange unit 1 can be removed from the clothes 100 when the clothes 100 are washed.

The heat conducting member 13 arranged inside the garment 100 is configured by a heat sink including a heat conducting plate 13a and a plurality of fins 13b. The heat conducting member 13 is arranged so that the heat conducting plate 13a is joined to one surface of the Peltier element 17 held by the partition plate 16. Further, in the heat conducting member 13, a space 13c for housing the fan 14 is formed inside the plurality of fins 13b, and the fan 14 is housed in the space 13c. The fan 14 is for blowing the air, which has been heat-exchanged by the heat conducting member 13, toward the inside of the garment 100.

The blower member 12 is a member that guides the heat-exchanged air sent out by the fan 14 to the space inside the garment 100. For example, the blower member 12 has a bottomless bowl shape, and is configured such that the open area thereof gradually increases as the distance from the partition plate 16 increases. Further, the blower member 12 is arranged such that the thread tail portion 12b surrounds the heat conducting member 13 and the fan 14, and the tip of the thread tail portion 12b is fixed to the partition plate 16. Further, in the blower member 12, an intake port 12a is formed in the peripheral wall of the thread tail portion 12b fixed to the partition plate 16, and the ambient air is passed through the intake port 12a, and the heat conduction member 13 is provided inside. It is a structure that can be made to flow into.

The fan guard 11 is a member that closes the air blowing port of the air blowing member 12 while ensuring air permeability. By providing the fan guard 11 at the air outlet of the air blowing member 12, it is possible to prevent clothes or the like from being entangled with the fan 14.

The heat conducting member 23 arranged on the outer side of the garment 100 is the same as the heat conducting member 13 described above. That is, the heat conducting member 23 is constituted by a heat sink having a heat conducting plate 23a and a plurality of fins 23b, and the heat conducting plate 23a is bonded to the other surface of the Peltier element 17 held by the partition plate 16. Is located in. Further, the heat conducting member 23 has a space for accommodating the fan 24 formed inside the plurality of fins 23b, and the fan 24 is accommodated in the space. The fan 24 is for blowing ambient air toward the heat conducting member 23.

The blower member 22 is a member that guides the heat-exchanged air discharged from the periphery of the heat conducting member 23 when the fan 24 operates in a direction away from the clothes 100. Similar to, for example, the blower member 12 described above, the blower member 22 has a bottomless bowl shape and is configured such that the open area thereof gradually increases as the distance from the partition plate 16 increases. The yarn tail portion 22b of the blower member 22 is arranged so as to surround the heat conducting member 23 and the fan 24, and the tip thereof is fixed to the partition plate 16. However, the peripheral wall of the yarn tail portion 22b of the blower member 22 is not provided with an intake port like the blower member 12.

The fan guard 21, like the fan guard 11 described above, is for protecting the fan 24 by blocking the air blowing port of the air blowing member 22 while ensuring air permeability.

By assembling the above-described components, the heat exchange unit 1 is divided into the inside and the outside of the garment 100 with the partition plate 16 in which the Peltier element 17 is incorporated sandwiched therebetween, as shown in FIG. The structure is almost symmetrical. Such a heat exchange unit 1 includes a Peltier element 17 and fans 14 and 24 as components that need to be energized. FIG. 1B is a block diagram showing a mechanism for controlling those parts. As a control mechanism of the heat exchange unit 1, a controller 5 and mobile batteries 6 and 7 are provided. The mobile batteries 6 and 7 are, for example, rechargeable batteries, and supply electric power to the controller 5. The controller 5 drives the Peltier element 17 and the fans 14 and 24 by supplying the electric power supplied from the mobile batteries 6 and 7 to the heat exchange unit 1. The controller 5 can switch between cooling and heating by switching the polarity of the direct current supplied to the Peltier element 17. However, the direction in which the fans 14 and 24 are driven (rotational direction) does not change regardless of whether cooling or heating. The controller 5 and the fans 13 and 24 as described above are carried while being housed in, for example, a pocket (not shown) provided in the clothes 100.

Next, the operation of the heat exchange unit 1 will be described with reference to FIG. First, when the fan 14 is driven inside the garment 100, ambient air is taken into the blower member 12 from the intake port 12a provided in the thread tail portion 12b of the blower member 12 as shown by an arrow F1. The air taken into the blower member 12 is heat-exchanged by the heat-conducting member 13, and the heat-exchanged air is sent out in the direction shown by the arrow F2 by the wind force of the fan 14. For example, at the time of cooling, the inner surface of the Peltier element 17 of the garment 100 is cooled, so that the heat conducting member 13 is also cooled. Therefore, the air taken in through the intake port 12a is cooled by the heat conducting member 13 and sent out to the inner space of the garment 100 by the fan 14. Further, during heating, the surface of the Peltier element 17 inside the garment 100 is heated, so that the heat conducting member 13 is also heated. Therefore, the air taken in from the intake port 12a is heated by the heat conducting member 13 and is sent out to the inner space of the garment 100 by the fan 14.

Next, on the outside of the garment 100, when the fan 24 is driven, the air around the heat exchange unit 1 is sent toward the Peltier element 17 as shown by an arrow F3. The air heading for the Peltier element 17 is heat-exchanged by the heat conducting member 23 and then heads to the outside of the heat conducting member 23. Since the yarn tail portion 22b of the blower member 22 is not provided with an intake port like the blower member 12, the air heading to the outside of the heat conducting member 23 moves along the inner wall of the blower member 22. .. Then, the heat-exchanged air is finally discharged from the peripheral portion of the fan guard 21 to the outside as shown by an arrow F4. For example, during cooling, the outer surface of the Peltier element 17 on the outer side of the garment 100 is heated, so that the heat conducting member 23 is also heated. Therefore, the air that has been heat-exchanged by the heat conducting member 23 is at a higher temperature than the surrounding air. The blower member 22 does not impair the comfort of the wearer by discharging such high temperature air in a direction away from the clothes 100. Further, since the outer surface of the Peltier element 17 on the outer side of the garment 100 is cooled during heating, the heat conducting member 13 is also cooled. Therefore, the air that has been heat-exchanged by the heat conduction member 23 is in a lower temperature state than the surrounding air. The blower member 22 discharges such low temperature air in a direction away from the clothes 100. Therefore, the comfort of the wearer is not impaired even during heating.

Next, the garment 100 to which the heat exchange unit 1 as described above is attached will be described. For example, by providing a hole of the same size as the open portion 25a of the fixing ring 25 in the cloth 101 of the back body of the garment 100 and fixing the partition plate 16 and the fixing ring 25 to the peripheral edge of the hole, The exchange unit 1 is attached. In the garment 100 to which the heat exchange unit 1 is attached in this manner, the air inside the garment 100 is cooled or heated by the Peltier element 17, and the cooled or heated air is circulated inside the garment 100 again by the fan 14. Since it is supplied, one Peltier element 17 can efficiently cool or heat the back of the garment.

Further, the fan 14 blows out the temperature-controlled air toward the back of the wearer. Therefore, the back of the clothing can be cooled by utilizing the heat of vaporization when the sweat of the clothing is vaporized especially during cooling. Furthermore, during cooling, dew condensation can be caused on the heat conducting member 13 cooled by the Peltier element 17 to dehumidify the space inside the garment 100.

As described above, the garment 100 to which the heat exchange unit 1 is attached can efficiently perform cooling or heating by reducing the volume of air to be cooled or heated, and at the time of cooling, further utilize the heat of vaporization to further cool. There are advantages that efficient cooling can be performed and the interior of the garment 100 is dehumidified, so that the comfort of the wearer can be improved. Further, since the back of the clothing can be effectively cooled or heated by one Peltier element 17, it is possible to reduce the power consumption, and the amount of power that can be supplied by the currently marketed mobile batteries 6 and 7 can be reduced. Even if it is taken into consideration, it can be continuously used for at least several hours, and exhibits a cooling ability or a heating ability that is sufficiently suitable for practical use.

By the way, the garment 100 as described above preferably has a certain space for circulating the air inside the garment 100 in order to maintain the cooling or heating efficiency in a constant state. Therefore, as shown in FIG. 2( b ), a spacer 30 is provided inside the garment 100 to form a space for circulating air between the body of the wearer and the cloth 101 around the heat exchange unit 1. It is preferable.

FIG. 5 is a cross-sectional view showing a state in which the garment 100 provided with the spacer 30 is worn. As shown in FIG. 5, by providing the spacer 30 inside the garment 100, a constant space X is secured between the cloth 101 of the garment 100 and the body 110 of the wearer around the attachment position of the heat exchange unit 1. be able to. The heat exchange unit 1 circulates the air whose temperature is adjusted in the space X. Such a spacer 30 prevents the clothes 100 from sticking to the body 110 of the wearer, even on a hot summer day, and distributes the temperature-controlled air in the space X to the body 110 of the wearer. It can be done.

FIG. 6 is an enlarged view of the spacer 30. The spacer 30 includes, for example, a flexible resin frame structure 31. The frame structure 31 mainly includes two vertical frames 31a and 31b and two horizontal frames 31c and 31d connected to the upper and lower ends of the two vertical frames 31a and 31b. The horizontal frame 31c is arranged at a position displaced rearward from the standing position of the two vertical frames 31a and 31b, and is not on the same plane as the two vertical frames 31a and 31b. The horizontal frame 3d is also arranged at a position shifted rearward from the standing position of the two vertical frames 31a and 31b, and is not on the same plane as the two vertical frames 31a and 31b. Both ends of the horizontal frames 31c and 31d are bent and connected to the upper and lower ends of the vertical frames 31a and 31b. Since the bent connecting portions of the vertical frames 31a and 31b and the horizontal frames 31c and 31d have flexibility, the space between the two vertical frames 31a and 31b can be easily widened. Further, since the vertical frames 31a and 31b and the two vertical frames 31a and 31b also have flexibility, it is possible to easily bend and deform each frame. Further, a pair of reinforcing frames 32, 32 is provided between the horizontal frames 31c, 31d. The reinforcing frames 32, 32 are also flexible resin frames.

For example, a cloth 33 having a hole 33a having the same size as the opening 25a of the fixing ring 25 is stretched between the pair of reinforcing frames 32. Therefore, the spacer 30 is attached to the garment 100 by mounting the heat exchange unit 1 with the hole 33a of the cloth 33 overlapping the hole formed in the garment 100. However, the manner of attaching the spacer 30 to the clothes 100 is not limited to this. For example, the reinforcing frames 32, 32 may be sewn directly to the garment 100, or may be attached to the garment 100 using a surface fastener or the like.

By providing such a spacer 30 inside the garment 100, it is possible to form the space X in which the temperature-controlled air is circulated. In addition, since the spacer 30 has flexibility, even if an object collides against the back of the garment 100, the spacer 30 serves as a cushion, which has an advantage of protecting a wearer. The material of the spacer 30 is not necessarily limited to the resin, and a metal material may be used as long as it exhibits a certain flexibility.

Although one embodiment of the present invention has been described above, the present invention is not limited to the contents described in the above embodiment, and various modifications can be applied.

For example, in the above embodiment, the case where one Peltier element 17 is provided in the heat exchange unit 1 is illustrated, but the number of Peltier elements 17 is not limited to one. For example, the heat exchange unit 1 may be provided with two or more Peltier elements 17.

Further, in the above embodiment, an example in which the heat exchange unit 1 is arranged on the cloth 101 at the back body of the garment 100 has been described. However, the position where the heat exchange unit 1 is attached is not necessarily limited to the back body cloth 101.

Although not particularly mentioned in the above embodiment, a lining may be provided further inside the cloth 101 of the garment 100. In the case of such a garment 100, the lining is located further inside than the heat exchange unit 1 and the spacer 30, and therefore, it is preferable to use a material such as a mesh material that does not lose breathability. Further, when the cloth 101 and the lining are sewn together at the hem of the garment 100, the spacer 30 may be attached only between the cloth 101 and the lining.
