The body warming/cooling device 1 of the embodiment includes a pair of first plates 11 provided so as to be in contact with each carotid artery A of the right side neck RN and left side neck LN of the user U; A pair of first Peltier elements 13 that cool or heat each, a second plate 12 provided in contact with the rear neck PN of the user U, and a second Peltier element 14 that cools or heats the second plate 12. and.

The body warming/cooling device 1 also includes a neck hanging member 16 provided with a pair of first plates 11 and a second plate 12, and a pair of first Peltier elements 13 and second Peltier elements 14. Furthermore, the body warming/cooling device 1 includes a heat exchange section 17, a power supply section 18, and an operation section 19 as other components described below.

FIG. 5 is a front view showing the neck hanging member 16 of the body warming/cooling device 1 of the embodiment. FIG. 6 is a rear view showing the neck hanging member 16 of the body warming/cooling device 1 of the embodiment. FIG. 7 is a side view showing the neck hanging member 16 of the body warming/cooling device 1 of the embodiment. FIG. 8 is a bottom view showing the neck hanging member 16 of the body warming/cooling device 1 of the embodiment.

The pair of first plate 11 and second plate 12 are made of, for example, a metal material such as aluminum. As shown in FIGS. 3, 4, 6, and 8, the first plate 11 is provided inside each of both ends of the neck hanging member 16 extending toward the front side. The second plate 12 is provided inside a curved central portion 29 on the back side of the neck hanging member 16, as shown in FIGS. 3, 5, 7, and 8.

The pair of first Peltier elements 13 are provided in contact with the pair of first plates 11, as shown in FIG. located inside. The second Peltier element 14 is provided in contact with the second plate 12 and is disposed inside a central portion 29 that is continuous with both ends of the neck hanging member 16 . The first plate 11 and the second plate 12 are thermally connected to the first Peltier element 13 or the second Peltier element 14.

In this way, the pair of first plate 11 and second plate 12 are distributed and arranged at three locations on the neck hanging member 16, thereby cooling the blood flowing through the carotid artery A so that the user U can cool down. Cooling can be concentrated in three areas: the right side neck RN and left side neck LN where the user U can effectively feel the cooling sensation, and the back neck PN where the user U can easily feel the cold sensation.

Therefore, according to the body warming/cooling device 1 of the embodiment, for example, a U-shaped plate continuous over the right side neck RN, the rear neck PN, and the left side neck LN is used to connect the neck N (hereinafter referred to as The right side neck RN, the left side neck LN, and the back neck PN are collectively referred to as the neck N.) Compared to a structure that cools the surrounding area, the heat transfer area can be made smaller, so the user U's neck N can be efficiently can be cooled down. As a result, the power consumption of the body warming/cooling device 1 is suppressed. When powered by a battery, it is possible to extend the continuous use time. In addition, by dispersing the first plate 11 and the second plate 12 at three locations in the neck hanging member 16, the movement of the neck N is restrained like the U-shaped plate described above. In addition, since the user U's feeling of pressure is suppressed, the user U's feeling of openness and the degree of freedom of movement of the neck N are increased, and a comfortable wearing feeling can be obtained.

Since the blood flow rate in the posterior cervical region PN is lower than that in the carotid artery A, the amount of heat absorbed by the second Peltier element 14 is smaller than the amount of heat absorbed by the first Peltier element 13. Therefore, a Peltier element smaller than the first Peltier element 13 is used as the second Peltier element 14. Thereby, the effect of cooling the posterior cervical region PN by the second Peltier element 14 is made smaller than the effect of cooling the blood flowing through the carotid artery A by the first Peltier element 13. The temperature of the second Peltier element 14 that cools the posterior cervical region PN is prevented from dropping too much, and the user U's sense of comfort is enhanced.

(Shape of first plate)
FIG. 9 is an enlarged view showing the neck hanging member 16 and the first plate 11 in the example. As shown in FIG. 9, the pair of first plates 11 have a contact area 21 in contact with the carotid artery A, and the contact area 21 has an opposing upper side 21a and a lower side 21b, an opposing front side 21c, and a rear side. It has a side 21d. The width W1 between the upper side 21a and the lower side 21b increases from the rear side 21d toward the front side 21c. The width W1 refers to the width in a direction perpendicular to the direction in which an upper section 16A of the neck hanging member 16, which will be described later, extends. In other words, the upper side 21a is formed to have an upward slope toward the front of the neck hanging member 16, the lower side 21b is formed to have a downward slope toward the front of the neck hanging member 16, and the width on the front side 21c side is W1 is larger than the width W1 on the rear side 21d side.

Further, in the contact area 21 of the pair of first plates 11, the front side 21c is inclined so that the upper side of the front side 21c is located in front of the user U than the lower side of the front side 21c, and the rear side 21d is inclined. The rear side 21d is inclined so that the upper side of the rear side 21d is located in front of the user U than the lower side of the rear side 21d. In other words, the front side 21c is formed to have an upward slope toward the tip of both ends of the neck hanging member 16 (front end 28 of the upper section 16A, which will be described later). Note that the upper side 21a, lower side 21b, front side 21c, and rear side 21d of the contact area 21 in this embodiment are each side along the outer periphery of the contact area 21, and include the curved portion of this outer periphery. .

In this way, the area of the contact area 21 of the first plate 11 is formed to increase toward the front side of the user U, so that the carotid artery triangle T, which will be described later, where the carotid artery A of the user U is located. (FIG. 10), and the size occupied by the contact area 21 with respect to the carotid artery triangle T can be ensured appropriately.

Further, the contact area 21 of the pair of first plates 11 is formed in a curved shape that swells toward the carotid artery A. For example, the center of the contact area 21 bulges toward the carotid artery A side from the upper side 21a, the lower side 21b, the front side 21c, and the rear side 21d. This makes it possible for the contact area 21 to properly contact the carotid artery A regardless of variations in the size of the neck N of the user U, and to improve the contact state between the first plate 11 and the carotid artery A. Stability is ensured. Note that the curved contact area 21 may be formed of a spherical surface or may be formed of a combination of a plurality of gently curved surfaces.

As shown in FIGS. 5 and 6, the second plate 12 has an elliptical contact area 22, and is arranged so as to touch both sides of the vertebrae (not shown) of the user's U's posterior cervical region PN. has been done. The contact area 22 is formed such that the center in the up-down direction, which is the Z direction, bulges toward the rear neck PN side, and the center in the up-down direction contacts the rear neck PN along the circumference.

(Shape of neck hanging member)
As shown in FIGS. 2, 3, and 4, the neck hanging member 16 of the body warming/cooling device 1 includes a U-shaped upper section 16A and a U-shaped lower section 16B disposed below the upper section 16A. and has. As shown in FIGS. 3, 5, and 8, the upper part 16A is provided with a pair of first plates 11 at both ends, and a second plate 12 at the center continuous with both ends. ing. As shown in FIGS. 3, 4, and 7, the neck hanging member 16 has one end of the upper part 16A in the direction in which the upper part 16A extends and one end of the lower part 16B in the direction in which the lower part 16B extends. At the same time, the other end of the upper stage part 16A and the other end of the lower stage part 16B are connected.

As shown in FIGS. 4, 5, 6, and 7, the lower part 16B is formed into a rod shape that is thinner than the upper part 16A, and is attached to the base of the neck N of the user U, that is, to the base of the neck. It is formed in a curved manner.

As shown in FIGS. 2 and 7, the upper part 16A and the lower part 16B are arranged with a gap 25 in the vertical direction, which is the Z direction of the neck hanging member 16. The void 25 is continuously formed from the right side neck RN and left side neck LN to the rear neck PN. In other words, by dividing the neck hanging member 16 into the upper stage part 16A and the lower stage part 16B, it becomes possible to secure the space 25 between the upper stage part 16A and the lower stage part 16B, and the neck hanging member 16 Since the neck N is restrained from being restrained by the neck hanging member 16, the feeling of pressure caused by the neck hanging member 16 is suppressed and the degree of freedom of movement of the neck N is increased, resulting in a comfortable wearing feeling.

Furthermore, in the neck hanging member 16, the vertical gap 25A in the right side neck RN and left side neck LN of the user U is larger than the vertical gap 25B in the rear neck PN. The rear side of the lower part 16B in contact with the rear neck part PN is curved upward, which is the rear side of the upper part 16A, so that the vertical gap 25B in the rear neck part PN is reduced. By ensuring a large vertical gap 25A in the right neck RN and left neck LN in this way, the feeling of pressure on the right neck RN and left neck LN by the neck hanging member 16 is suppressed, and the neck hanging member The feeling of openness of the neck N in the wearing state of No. 16 is enhanced, and a comfortable feeling of wearing is obtained.

Further, as shown in FIG. 8, on the XY plane (hereinafter referred to as a horizontal plane), the lower part 16B is arranged outside the upper part 16A with respect to the neck N of the user U, and The entire neck hanging member 16 is formed into a U-shape by arranging the outer circumferential side and the inner circumferential side of the lower part 16B to overlap. Therefore, the upper stage part 16A is arranged closer to the neck N of the user U than the position of the lower stage part 16B.

The neck hanging member 16 is made of, for example, a resin material such as polypropylene (PP) or thermoplastic polyurethane (TPU). The lower portion 16B is formed into a rod shape using an example of an elastic material such as polypropylene (PP) or thermoplastic polyurethane (TPU). The lower section 16B is elastically deformed, that is, flexibly bent, relative to the upper section 16A, so that the lower section 16B and the upper section 16A are connected to be movable relative to each other. Therefore, the upper section 16A can flexibly move to follow the movement of the neck N of the user U. In other words, the lower section 16B is formed to be elastically deformed relative to the upper section 16A in accordance with the movement of the user's U's shoulders and the like. In addition, as described above, by ensuring the gap 25 (25A, 25B) between the upper part 16A and the lower part 16B, the upper part 16A and the lower part follow the movement of the neck N of the user U. The degree of freedom of each movement of the portion 16B is increased, and a comfortable wearing feeling can be obtained.

Therefore, when the neck N is pressed against the upper section 16A due to the movement of the neck N, shoulders, etc. of the user U, the upper section 16A can smoothly move toward the lower section 16B. , the neck N of the user U is prevented from being compressed by the upper section 16A.

(Positioning part)
As shown in FIGS. 1 and 2, FIG. 7, and FIG. 9, the neck hanging member 16 is placed at a position where the pair of first plates 11 are in contact with each carotid artery A of the right side cervical RN and the left side cervical LN. It has a positioning part 27 that is placed on the body of the user U so as to position the body of the user U. The positioning portion 27 is formed by a curved portion on the front side of the lower portion 16B of the neck hanging member 16, and the pair of positioning portions 27 are integrally formed in the lower portion 16B.

Each positioning portion 27 is formed at a position in contact with the clavicle B of the user U, as shown in FIGS. 1, 2, and 9. Therefore, by wearing the neck hanging member 16 so that each positioning part 27 of the lower part 16B of the neck hanging member 16 is placed on the clavicle B, each of the first plates 11 provided on the upper part 16A is It can be easily positioned in the vertical direction of the neck N, and also easily positioned in the horizontal direction of the neck N. Furthermore, by positioning each of the first plates 11 with respect to the clavicle B, the pair of positioning parts 27 can easily position the first plates 11 and improve the stability of the positioning state of the first plates 11.

Furthermore, since the lower part 16B having the positioning part 27 is made of an elastic material as described above, even if the collarbone B, shoulder, etc. move while the neck hanging member 16 is attached, the lower part 16B Since fluctuation in the position of the first plate 11 is suppressed by bending, the stability of the state in which the first plate 11 is positioned by the positioning portion 27 is increased. Therefore, since the contact area of the first plate 11 with the right side neck RN or the left side neck LN can be maintained, the carotid artery A can be efficiently cooled.

(Shape of front end of neck hanging member)
As shown in FIG. 9, the width W2 between the upper edge 28a and the lower edge 28b of the pair of front ends 28, which are both ends of the upper part 16A of the neck hanging member 16, is in front of the user U. It's expanding towards. The width W2 refers to the width in the direction perpendicular to the direction in which the upper section 16A of the neck hanging member 16 extends. Further, the upper edge 28a of the front end portion 28 is formed to have a downward slope toward the front of the user U. Similar to the upper edge 28a, the lower edge 28b of the front end portion 28 is formed to have a downward slope toward the front of the user U. Further, as shown in FIGS. 2, 7, and 9, in the front end portion 28, the lower edge 28b and the upper edge 28a of the upper stage portion 16A are formed such that the width on the front side is wide and the width on the rear side is narrow. There is.

The front end 28c of the neck hanging member 16 is inclined such that the upper edge 28a side of the front edge 28c of the front end 28 is located in front of the user U rather than the lower edge 28b side. Note that, as shown in FIGS. 5 and 8, the pair of front end portions 28 in the embodiment are curved so that their tips approach each other in the direction in which the upper stage portion 16A extends. Therefore, to put the above-mentioned inclined shape of the front edge 28c in other words, the front edge 28c of the front end 28 has an upper edge 28a side in the direction in which the upper step part 16A extends than a lower edge 28b side of the front edge 28c of the front end part 28. It is slanted so that it is located on the tip side.

By forming the width of the front end portion 28 in the Z direction to be larger than the rear side of the upper stage portion 16A, the front end portion 28 faces the carotid artery triangle T (FIG. 10), which will be described later, where the carotid artery A of the user U is located. The first plate 11 can be arranged in such a manner that the first plate 11 can be arranged in such a manner that the first plate 11 can be appropriately sized with respect to the carotid artery triangle T. Therefore, the size of the contact area 21 of the first plate 11 disposed at the front end portion 28 can be expanded, and the size of the contact area 21 of the first plate 11 that occupies with respect to the carotid artery triangle T can be increased. Properly secured. In addition, by forming the front end portion 28 in the above-described shape, a space is secured around the throat of the user U's front neck AN (FIG. 2), thereby reducing the feeling of pressure on the user U. This increases the sense of openness of the neck N when the neck hanging member 16 is worn, and provides a comfortable wearing feeling.

(Positional relationship between the first plate and the neck)
FIG. 10 is a side view for explaining the positional relationship between the right neck RN, the left neck LN, and the first plate 11 when the user U wears the neck hanging member 16 in the embodiment. In FIG. 10, the area of the carotid artery triangle T is indicated by diagonal lines. As shown in FIG. 10, when the user U wears the neck hanging member 16, the pair of first plates 11 are attached to the front end of the upper portion 16A so as to be in contact with the region of each carotid artery triangle T of the user U. It is located at 28. That is, the first plate 11 is arranged with the position of the carotid artery triangle T as a reference, and a range where the contact area 21 of the first plate 11 and the area of the carotid artery triangle T overlap is appropriately secured. Thereby, the contact area 21 of the first plate 11 can easily and smoothly come into contact with the carotid artery A located in the carotid artery triangle T, and the blood flowing through the carotid artery A can be appropriately cooled.

(carotid triangle)
FIG. 11 is a schematic diagram for explaining the carotid artery triangle in the example. As shown in FIG. 11, the carotid triangle T is the region where the carotid artery A is located, and includes the right carotid triangle located in the right cervical RN and the left carotid triangle located in the left cervical LN. include. In detail, the carotid artery triangle T includes a front edge T1 where the thyroid region 101, larynx 102, lower hyoid bone 103, and hyoid bone portion 104 are located, an upper edge T2 where the submandibular triangle 105 is located, and a sternocleidomastoid. It refers to the triangular area surrounded by the rear edge T3 and where the protruding muscle portion 106 is located.

By setting the shape of the front end portion 28 of the neck hanging member 16 and the shape of the contact area 21 of the first plate 11 to correspond to such a carotid artery triangle T, the carotid artery A is connected by the first plate 11. It can cool the flowing blood. Note that the contact area 21 of the first plate 11 is formed so that the size around the neck N is larger than the size of the area of the average carotid artery triangle T, and the size of the contact area 21 around the neck N of the user U is larger than the size of the area of the average carotid artery triangle T. It is set to appropriately contact the area of the carotid artery triangle T regardless of variations in the area.

(Flow path of neck hanging member)
FIG. 12 is a perspective view showing a flow path included in the neck hanging member 16 of the body warming/cooling device 1 of the embodiment. FIG. 13 is a schematic diagram showing a flow path included in the neck hanging member 16 in the example.

As shown in FIG. 12, the neck hanging member 16 has a tube member 31 that forms a flow path 32 for sending cooling water as a heat medium to the first Peltier element 13 and the second Peltier element 14. The tube member 31 is provided inside the upper section 16A and the lower section 16B of the neck hanging member 16, and is arranged along the direction in which the upper section 16A and the lower section 16B extend, respectively. Note that the heat medium is not limited to cooling water, and other temperature regulating liquids such as cooling oil may be used.

As shown in FIGS. 12 and 13, the flow path 32 of the tube member 31 includes a first flow path 32A extending from the second Peltier element 14 to one of the pair of first Peltier elements 13; A second flow path 32B extending from the first Peltier element 13 to the other first Peltier element 13, and a third flow path 32C extending from the other first Peltier element 13 to the second Peltier element 14.

Inside the neck hanging member 16, the cooling water supplied from the outside on the rear side of the neck hanging member 16 flows in the order of the first flow path 32A, the second flow path 32B, and the third flow path 32C, and the cooling water flows through the neck hanging member 16 in this order. It is sent to the outside from the rear side of 16. As shown in FIG. 13, the flow path 32 is routed so as to supply cooling water to the pair of first Peltier element 13 and second Peltier element 14. The cooling water exchanges heat with each of the

Therefore, as shown in FIG. 12, inside the upper stage part 16A, there is a first flow path 32A through which cooling water flows from the rear of the upper stage part 16A toward one front end 28 of the upper stage part 16A, and A third flow path 32C is provided through which cooling water flows from the other front end portion 28 toward the rear of the upper stage portion 16A. A second flow path 32B through which cooling water flows from one end of the lower part 16B toward the other end is provided inside the lower part 16B.

That is, the cooling water that entered the flow path 32 from the rear of the upper stage section 16A flows through the upper stage section 16A along the first flow path 32A, flows through the lower stage section 16B along the second flow path 32B, and flows through the third flow path. 32C through the upper section 16A, it flows inside the neck hanging member 16 along a flow path 32 formed like a so-called single stroke, and exits from the rear of the upper section 16A to the outside of the neck hanging member 16. Therefore, each of the upper stage part 16A and the lower stage part 16B can be used as a flow path.

Therefore, the route of the cooling water flow path 32 in the neck hanging member 16 can be simplified and the neck hanging member 16 can be formed compactly, so that the neck hanging member 16 can be made smaller and lighter. In addition, inside the neck hanging member 16, the first flow path 32A, the second flow path 32B, and the third flow path 32C are arranged apart from each other, so that heat exchange occurs between each flow path 32A, 32B, and 32C. Since this can be avoided, the cooling capacity of the first Peltier element 13 and the second Peltier element 14 can be increased. In addition, in the neck hanging member 16, the upper part 16A and the lower part 16B are arranged with a gap 25 in between, so that between the first flow path 32A and the second flow path 32B, and between the second flow path 32B and the second flow path 32B. Heat exchange with the third flow path 32C can be blocked. Thereby, the cooling capacity of the first Peltier element 13 and the second Peltier element 14 can be further enhanced.

Furthermore, in the embodiment, the amount of heat absorbed by the second Peltier element 14 is smaller than the amount of heat absorbed by the first Peltier element 13, as described above. Therefore, in the flow path 32, the cooling water first passes through the second Peltier element 14, which has a small amount of heat absorption, so that the temperature of the cooling water is prevented from increasing significantly, and after passing through the second Peltier element 14, The first Peltier element 13 can be appropriately cooled by the cooling water having a low temperature.

(Tube member pull-out position)
As shown in FIG. 2, FIG. 4, FIG. 7, and FIG. is being pulled out. Specifically, the tube member 31 is pulled out in the horizontal direction from the back surface of the central portion 29 of the upper section 16A of the neck hanging member 16, where the second Peltier element 14 is arranged. The center part 29 of the upper part 16A from which the tube member 31 is pulled out from the neck hanging member 16 is located above the rear neck PN, and the position at which the tube member 32 is pulled out is above the collar of a typical garment. It is arranged so that Moreover, since the tube member 31 is pulled out horizontally from the upper section 16A, contact between the collar of the user U's clothes and the tube member 31 is avoided, and the flowability of the cooling water is suppressed from being hindered.
