Peltier element unit and cooling garment equipped with the same

Abstract

To provide a Peltier element unit and a cooling garment equipped with the same capable of preventing an exhaust port from being blocked and preventing the body from being exposed to exhaust hot air even when the Peltier element unit is attached to the armpit.SOLUTION: In a Peltier element unit, a cover part 22 can change the direction of an air flow from a central axis C direction to a vertical direction. A male screw part 37 is present inside a cooling garment 1, and an exhaust port 29a of the cover part 22 is opened right above a flange face. Therefore, the height of the cover part 22 protruding outside the cooling garment 1 is low. Further, although a ring part 50 is screwed from the inside of the cooling garment 1 because the male screw part 37 is located inside the cooling garment 1, the interference between a wiring cord 40 and the ring part 50 occurring in this case is eliminated by forming a passage so that the cloth of a fitting port 10 takes a detour in a recessed portion 42.SELECTED DRAWING: Figure 3

Description

Technical Field

[0001] The present invention relates to a cooling garment using a Peltier element.

Background Art

[0002] As one of the countermeasures against heat stroke to protect workers, a cooling garment that cools the body to regulate body temperature is known.

[0003] For example, Patent Document 1 discloses a garment to which a blower device is detachable. The housing of the fan unit is cylindrical and has an intake portion, a flange portion, a male screw portion, and an exhaust portion in order from above, and a motor with a fan facing upward is attached to the bottom. By screwing a ring body from the inside of the outer fabric including the back body to the male screw portion of the housing, the outer fabric of the attachment port is sandwiched between the flange portion of the fan unit on the outer side of the outer fabric and the flange portion of the ring body on the inner side to attach the fan unit.

[0004] The wiring cord to the blower device is wired inside the garment. In the blower device, a DC jack is provided in the wiring cord and a socket is provided in the blower device so that the wiring cord can be separated from the blower device. This is because when the ring body is screwed after connecting the wiring cord to the blower device, the ring body interferes with the wiring cord.

[0005] Also, Patent Documents 2 and 3 disclose a cooling garment in which a Peltier element unit having a cooling or heating surface is attached to an attachment port formed in the back body of the garment. The Peltier element unit is a unit including, in addition to the fan unit, a Peltier element, a heat radiating plate that abuts against the Peltier element, and an exhaust fan that exhausts heat from the heat radiating plate to the outside.

[0006] Since the Peltier element unit does not send a large amount of air into the garment like the blower device of Patent Document 1, it is small in capacity and size. Since the operating part is also small, the attachment port has a relatively soft and simple structure made of only fabric.

[0007] In the Peltier element unit disclosed in Patent Document 2, a flange that projects radially in an annular plate shape from the outer peripheral end of the Peltier element mounting portion formed in a cylindrical shape is provided. In the Peltier element unit disclosed in Patent Document 3, air holes are provided on the Peltier element mounting portion, and an inner flange is further provided thereon. And in the Peltier element units disclosed in Patent Documents 2 and 3, the exhaust fan cover portion that surrounds the exhaust fan has a cylindrical shape, and exhaust holes for exhaust are provided between the disk-shaped top portion located on the top side of the cylindrical shape and the side portion that connects to the ring body. And on the exhaust fan cover portion, a flange and a screw groove are formed in order from the bottom on the outer surface.

[0008] These Peltier element units are inserted into the mounting opening provided in the back body from the inside of the clothing, and the flange is pressed against the back body from the inside. Next, the ring body is brought close to the exhaust fan cover portion from the outside of the back body, and the screw groove formed on the inner surface of the ring body and the screw groove formed on the outer surface of the exhaust fan cover portion are screwed together with each other. As a result, the inner peripheral edge of the mounting opening of the back body is sandwiched by the flange and the ring body. In these Peltier element units, since the ring body is attached from the outside by screwing, the Peltier element unit can be easily attached to and detached from the clothing. Further, since the outer ring body does not interfere with the inner wiring cord, the Peltier element unit and the wiring cord are fixedly connected.

Summary of the Invention

Problems to be Solved by the Invention

[0010] A Peltier element is known as a semiconductor element with the Peltier effect, which is formed by joining an N-type semiconductor and a P-type semiconductor. When a direct current is passed through the Peltier element in a certain direction, heat is absorbed on one side and generated on the other side. Cooling can be achieved by arranging the heat-absorbing side of the surface on the body side of the wearer. On the other hand, since the other side is heated by the combined heat generation of the heat absorbed and the heat generated by the consumed electric power, it is important to exhaust the heat.

[0011] In any of the Peltier element units disclosed in Patent Documents 2 and 3, since the exhaust heat air blows upward, if the exhaust hole is blocked in a way of use, for example, when wearing clothes from the top, or when the exhaust port is compressed and blocked from above by a lanyard or a belt of a rucksack hitting it, the exhaust heat of the Peltier element unit will be trapped, causing a temperature rise and damage.

[0012] Also, when the Peltier element unit is placed under the armpit, the exhaust hole of the Peltier element unit will be blocked when the two arms (upper arms) are lowered, or the hot air will hit the two arms.

[0013] The present invention has been made in view of the above, and an object thereof is to provide a Peltier element unit that avoids blocking of the exhaust port and also prevents the exhaust heat air from hitting the body even when installed under the armpit, and a cooling garment equipped with the same.

Means for Solving the Problems

[0014] The Peltier element unit and the cooling garment according to the present invention include a Peltier element and an exhaust fan, and a ring body is screwed and mounted from the inside of an attachment opening formed in the cooling garment to a unit body having a flange surface between a cover portion and a shaft portion. The Peltier element unit is such that the proximal end of the wiring cord for supplying power to the Peltier element and the exhaust fan is fixed at a position equal to or higher than the flange surface so that the proximal end cannot be detached from the inside of the unit body. The shaft portion is cylindrical with the central axis as the center, and has, in order from above, a male screw portion provided with a male screw that is centered on the central axis and with which the ring body is screwed, an intake portion with an intake opening, and a Peltier portion to which a Peltier element is attached. In the cover portion, an exhaust fan that blows air upward along the central axis is attached to the top, and an exhaust opening is formed only in one direction perpendicular to the central axis around the top. In other directions, the air flow direction is directed toward the exhaust opening by being surrounded by a sloped surface portion that slopes from the top toward the hem edge. The wiring cord extends outside the unit body in the one direction in which the exhaust opening is formed. The recessed portion that is recessed upward from the flange surface along the central axis is provided at the position of the wiring cord, has a gap between its inner wall surface and the wiring cord, and the flange surface is interrupted at the location of the recessed portion and is continuous with the inner wall surface of the recessed portion.

Advantages of the Invention

[0015] According to the present invention, the cover portion can change the direction of the air flow in the central axis direction to a vertical direction and cause it to flow. Further, by causing the male screw portion to be inside the cooling garment, it is possible to open the exhaust port of the cover portion directly above the flange surface. For this reason, it is possible to reduce the height of the cover portion that protrudes outside the cooling garment. Further, since the male screw portion is inside the cooling garment, the ring body is screwed from the inside of the cooling garment. Regarding the interference between the wiring cord and the ring body that occurs in this case, the recessed portion forms a path through which the fabric of the attachment opening can detour, thereby eliminating the interference.

Embodiments for Carrying Out the Invention

[0017] Referring to FIGS. 1A and 1B, a cooling garment 1 according to the present embodiment is a vest having an attachment opening 10 to which a Peltier element unit 20 (described later with reference to FIG. 3) can be attached. A plurality of attachment openings 10 (hereinafter, may be denoted by reference numerals 10a to 10h depending on the attachment location) are provided so that the position for attaching the Peltier element unit 20 can be appropriately selected according to the wearer's preference. The cooling garment 1 has a front body 2, a back body 3, an armhole part 4, a side body 5, a standing collar 6, and a shoulder yoke 7. In the figure, the meshed portions of the front body 2, the back body 3, and the standing collar 6 represent mesh fabrics. The attachment opening 10 is reinforced by folding and sewing the fabric along its inner peripheral edge. It may be finished and reinforced with a round edge.

[0018] Attachment openings 10a and 10b are provided on the left and right of the lateral side under the armpit of the front body 2. The front body 2 is configured by combining a separate fabric of a meshed fabric 2a on the chest side and a ventral fabric 2b with a sewing line c1, and a pocket 8 is provided on the ventral fabric 2b. The pocket 8 can store a battery (not shown) for driving the Peltier element unit. The front fastener 9 extends from the front body 2 to the tip of the standing collar 6 so that the two can be opened and closed.

[0019] The back body 3 is configured by combining a central stretch fabric 3a and left and right meshed fabrics 3b with a sewing line c2. Attachment openings 10c and 10d are provided on the left and right of the lateral side under the armpit of the back body 3, and an attachment opening 10e is provided at the center under the collar. Also, the left and right side bodies 5 are made of stretch fabric, and attachment openings 10f and 10g are provided respectively. The side body 5 is sewn to the front body 2 from the sewing line c3 and to the back body 3 from the sewing line c4. Although almost no stretchability can be expected for the meshed fabrics of the front body 2 and the back body 3, the cooling garment 1 can be closely attached to the body due to the stretching of the stretch fabric 3a of the back body 3 and the stretch fabric of the side body 5.

[0020] Figure 2A shows the state where the standing collar 6 is unfolded. An attachment opening 10h is open at the collar neck (the nape part). The upper side 61 of the standing collar 6 is shorter than the lower side 62 that forms an arc. The distance between the upper side 61 and the lower side 62 at the center position cc of the standing collar 6 is longer than the lengths of the end sides 63 and 64.

[0021] When the lower side 62 is attached to the collar opening that continues to the front body 2, the back body 3, and the shoulder yoke 7, as shown in Figure 2B, the collar neck will fall forward. Therefore, when the Peltier element unit 20 is worn, the cooling surface CP (described later) can be applied to the side of the neck. Also, the standing collar 6 is composed of mesh fabrics 6a and 6c and stretch fabric 6b. By continuously arranging the stretch fabric 6b over the upper side 61 and the lower side 62, it has elasticity around the neck. For this reason, when the tips (end sides 63 and 64) of the standing collar 6 are fastened with the fastener 9, due to the elasticity of the stretch fabric 6b, the cooling surface CP can be further pressed against the side of the neck.

[0022] Fig. 3 shows the appearance of the Peltier element unit 20. Fig. 3A is a perspective view, Fig. 3B is a front view, Fig. 3C is a sectional view, Fig. 3D is a plan view, Fig. 3E is a bottom view, Fig. 3F is an exploded sectional view of the unit body 21, and Fig. 3G is an enlarged view of the recessed portion 42. The Peltier element unit 20 is separated into a unit body 21 and a ring body 50 (see Fig. 3B). The unit body 21 has an octagonal mushroom-shaped appearance in plan view. The cover portion 22 corresponds to the umbrella portion of the mushroom shape. The skirt edge R of the cover portion 22 is octagonal in plan view. The inclined surfaces 24 to 28 gently inclined from the top portion 23 of the cover portion 22 continue to the skirt edge R. The inclined surfaces 24 to 28 are not provided in one direction (referred to as the exhaust direction ex) perpendicular to the central axis C around the top portion 23. In the exhaust direction ex, an exhaust port portion 29 that descends from the top portion 23 downward along the central axis C and a guiding surface portion 30 that continues flatly from the exhaust port portion 29 to the skirt edge R are provided. An exhaust port 29a is opened in the exhaust port portion 29. Support surface portions 31 and 32 are provided at both ends of the guiding surface portion 30. The support surface portions 31 and 32 rise upward from the guiding surface portion 30 along the central axis C. They are connected to the inclined surfaces 33 and 34 that are continuously connected to the adjacent inclined surfaces 27 and 28 from the top portion 23 toward the skirt edge R. Therefore, around the top portion 23, the portion of the cover portion 22 that is open to the outside air is only the exhaust port 29a of the exhaust port portion 29. Note that the lower side of the central axis C is the body side of the wearer, and the upper side of the central axis C is the outside.

[0023] The shaft portion 35 extending downward from the cover portion 22 is cylindrical with a central axis C having a smaller diameter than the cover portion 22, and its diameter corresponds to the diameter of the mounting port 10. The shaft portion 35 has a flange portion 36, a male screw portion 37, an intake portion 38, and a Peltier portion 39 on the central axis C. A male screw is formed on the outer peripheral surface of the male screw portion 37. The center of the male screw coincides with the central axis C. A large number of intake holes 38a for taking air into the unit body 21 are opened in the peripheral wall of the intake portion 38. The lower surface of the flange portion 36 is the flange surface between the cover portion 22 and the shaft portion 35, and contacts the mounting port 10 from the outside.

[0024] Referring to FIG. 3C, the proximal end of the wiring cord 40 that supplies power to the Peltier element unit 20 is stopped by a stopper 41, and the stopper 41 is fixed so as not to be detachable from within the unit body 21. The wiring cord 40 is provided in the exhaust direction ex. There is no intervening separation mechanism such as a DC jack that can separate the wiring cord 40 from the Peltier element unit 20. A recess 42 that surrounds the wiring cord 40 with a bridge-shaped inner wall surface is provided in the cover portion 22 at the position of the wiring cord 40. The recess 42 is a portion that depresses upward in the direction of the central axis C from the flange surface of the flange portion 36. The flange surface is interrupted at the location of the recess 42 and is continuous with the inner wall surface of the recess 42. When the Peltier element unit 20 is attached to the attachment port 10, most of the fabric of the attachment port 10 is sandwiched between the flange surface of the flange portion 36 and the fastening surface 53, but in the recess 42, it detours above the wiring cord 40. The fabric of the attachment port 10 that detours the wiring cord 40 takes shelter between the inner wall surface of the recess 42 and the wiring cord 40.

[0025] The Peltier portion 39 of the shaft portion 35 is a portion where the Peltier element 43 is attached inside. A heat transfer plate 44 is in contact with the lower surface of the Peltier element 43. The cooling surface CP of the heat transfer plate 44 cools the wearer's body by contacting the wearer's body. On the other hand, a heat dissipation fin 45 is in contact with the upper surface of the Peltier element 43. The heat dissipation fin 45 conducts the heat generated from the Peltier element 43. The heat transfer plate 44 and the heat dissipation fin 45 are formed of a metal such as aluminum, for example.

[0026] Inside the cover portion 22, an exhaust fan 46 is attached to the top portion 23. The exhaust fan 46 is positioned directly above the heat dissipation fin 45 and blows air across the heat dissipation fin 45 from the intake hole 38a to the exhaust port 29a. The heat dissipation fin 45 heated by the Peltier element 43 is cooled by this air blowing.

[0027] Referring to FIG. 3F, the cover portion 22 is an integrally molded resin component. The shaft portion 35 is also an integrally molded resin component. The shaft portion 35 has a flange portion 47 that rises in the direction of the central axis C from the outer periphery of the flange portion 36. The flange portion 47 is fitted inside the skirt edge R of the cover portion 22, and the shaft portion 35 and the cover portion 22 are coupled together.

[0028] Referring to FIG. 3C, on the inner peripheral surface 51 of the ring body 50, a female screw is formed. The ring body 50 is a solid resin molded member up to near the outer peripheral surface 52 while maintaining the height in the direction of the central axis C of the inner peripheral surface 51. Since it is a solid member, a plurality of concave grooves 54 are formed on the outer peripheral surface 52, enabling good finger engagement and stable operation. The upper surface of the ring body 50 faces the flange surface of the flange portion 36 and serves as a fastening surface 53 that sandwiches the fabric of the mounting port 10. The fastening surface 53 is a surface parallel to the cooling surface CP of the heat transfer plate 44. Also, the flange surface of the flange portion 36 is a surface parallel to the cooling surface CP except at the location of the recessed portion 42.

[0029] Referring to FIG. 3G, the recessed portion 42 will be described. FIG. 3G shows the relationship between the height of the recessed portion 42, the height of the wiring cord 40 drawn out from the stopper 41, the height of the flange surface of the flange portion 36, and the height of the fastening surface 53 of the ring body 50. The base end of the wiring cord 40 is fixed by the stopper 41 at a position equal to or higher than the flange surface of the flange portion 36. A gap 100 is provided between the wiring cord 40 and the inner wall surface of the recessed portion 42. Also, the fastening surface 53 of the ring body 50 shortens the gap 101 as it is screwed toward the flange surface of the flange portion 36. When the Peltier element unit 20 is attached to the mounting port 10, the fabric of the mounting port 10 around the wiring cord 40 retracts into the gap 100. The remaining fabric of the mounting port 10 is sandwiched by the gap 101. The attachment to the mounting port 10 will be further described with reference to FIG. 4.

[0030] FIG. 4 shows how the Peltier element unit 20 is attached to the mounting port 10 of the cooling garment 1. In FIG. 4A, the unit body 21 and the ring body 50 are separated. In FIG. 4B, the unit body 21 is passed from the inside (the body surface side) to the outside of the mounting port 10 of the cooling garment 1. The cover portion 22 and the flange portion 36 protrude to the outside of the cooling garment 1, and the male screw portion 37 of the shaft portion 35 remains inside the cooling garment 1 after descending. The flange surface of the flange portion 36 is in contact with the cooling garment 1. The wiring cord 40 remains inside the cooling garment 1.

[0031] The ring body 50 is attached to the shaft portion 35 from the inside of the mounting port 10 of the cooling garment 1 (FIG. 4C). The female screw formed on the inner peripheral surface 51 of the ring body 50 is screwed with the male screw of the male screw portion 37. As a result, most of the fabric at the inner peripheral edge of the mounting port 10 is sandwiched between the flange surface of the flange portion 36 and the fastening surface 53 of the ring body 50. As an exception, the fabric of the mounting port 10 on the wiring cord 40 is retracted into the gap between the inner wall surface of the recessed portion 42 and the wiring cord 40.

[0032] In FIG. 4D, when the exhaust fan 46 is operated, the air inside the cooling garment 1 is taken into the shaft portion 35 from the intake holes 38a. Since the height h1 of the male screw portion 37 is secured between the intake holes 38a and the fabric of the cooling garment 1, it is possible to prevent the intake port from being blocked by the fabric of the cooling garment 1. Inside the cover portion 22, the air flow by the exhaust fan 46 is changed in direction from the central axis C direction to the exhaust direction ex by the inclined surfaces 24 to 28, and the inclined surfaces 33, 34, and is guided to the exhaust port 29a.

[0033] The exhaust port 29a faces the exhaust direction ex along the fabric of the cooling garment 1. Here, the exhaust direction ex is also a direction in a plane parallel to the cooling surface CP of the heat transfer plate 44. Since the cooling surface CP is in contact with the wearer's body, the fabric of the cooling garment 1 worn by the wearer is also parallel to the cooling surface CP. The exhaust from the exhaust port 29a flows in a direction along the fabric of the cooling garment 1.

[0034] By disposing the male screw portion 37 inside the cooling garment 1, it is possible to open the exhaust port of the cover portion 22 directly above the flange surface. For this reason, the height of the cover portion 22 protruding outside the cooling garment 1 can be reduced. Further, since the male screw portion 37 is present inside the cooling garment 1, the ring body 50 is screwed from the inside of the cooling garment 1. Regarding the interference between the wiring cord 40 and the ring body 50 that occurs in this case, the depression portion 42 forms a path through which the fabric of the attachment port 10 can detour, thereby eliminating the interference.

[0035] The Peltier element unit 20 is attached to the attachment port 10, the wiring cord 40 is connected to a battery (not shown), and the battery is housed in the pocket 8 to complete the preparation. A controller (not shown) is attached in the middle of the wiring cord 40 to turn the power on / off and set the cooling intensity. As the cooling intensity, for example, a fluctuation mode in which the strength is repeated every 10 seconds may be selectable.

[0036] FIG. 5A shows the cooling garment 1 with the Peltier element unit 20 attached to the attachment port 10. Each Peltier element unit 20 is attached with the direction of the exhaust port 29a facing the ground. The exhaust flow heated by the heat from the exhaust port 29a flows downward. When the Peltier element unit 20 is attached to the attachment ports 10f and 10g under the armpits, the exhaust from the exhaust port 29a is exhausted toward the ground, and the lower arms lowered are not warmed. Further, since the exhaust port 29a is open facing the ground, the exhaust port 29a is not blocked by the lowered lower arms. The direction of the wiring cord 40 also extends downward in the same direction as the exhaust port 29a and does not interfere with the space under the armpits. Further, the outside of the inclined surfaces 24 to 28, 33, and 34 has the same inclination as the inside, reducing the discomfort when hitting the arm.

[0037] Also, the exhaust air from the Peltier element unit 20 at the attachment port 10h of the standing collar 6 is exhausted in the direction of the back body 3. The cooling garment 1 of the present embodiment is assumed to be worn over a fan-equipped garment that performs air cooling. Most of such fan-equipped garments have collars to control the air flow. Since the cooling garment also has a standing collar, it is assumed that the two will overlap. However, the exhaust port 29a of the Peltier element unit 20 is directed towards the back body 3 and will not be blocked. The exhaust air discharged downward will diffuse into the air flow of the fan-equipped garment and come out from the collar opening. If the exhaust port of the Peltier element unit 20 is installed upward, the heated exhaust air will directly hit the back of the head, but such inconvenience can be avoided. Also, the direction of the wiring cord 40 is extended downward in the same direction as the exhaust port 29a and does not interfere with the space of the collar.

[0038] Also, the exhaust air from the exhaust port 29a passes over the guiding surface portion 30, but support surface portions 31, 32 are provided on both sides of the guiding surface portion 30. Even if the garment worn over the cooling garment 1 is pressed and covers the Peltier element unit 20, the passage above the guiding surface portion 30 is ensured by the support surface portions 31, 32 and the exhaust air will not be blocked.

[0039] In FIG. 5B, even if the ring body 50 accidentally falls off, since the wiring cord 40 of the Peltier element unit 20 is inside the cooling garment 1, the unit body 21 will not fall off significantly while being caught by the attachment port 10. If the unit body 21 falls off inside the cooling garment, it is possible to prevent the unit body 21 with the wiring cord 40 attached from coming out from the hem of the cooling garment 1.
