[Modes for carrying out the invention]

[0010] The following describes specific embodiments of this disclosure. However, some unnecessarily detailed descriptions may be omitted. For example, detailed descriptions of already well-known matters or redundant descriptions of substantially identical configurations may be omitted. This is to avoid the following description becoming unnecessarily verbose and to facilitate understanding by those skilled in the art. The inventors provide the accompanying drawings and the following description to enable those skilled in the art to fully understand this disclosure, and do not intend to limit the subject matter described in the claims. In the following description, identical or similar components are denoted by the same reference numerals. (Embodiment 1)

[0011] First, I will explain the overall structure of Cooling Suit 1 (also known as Water-Cooled Cooling Suit), and then I will explain the details of each component. (Regarding the cooling suit as a whole)

[0012] The following outline of a cooling suit 1, which represents one aspect of this disclosure, will be described with reference to drawings. Figure 1 is a schematic front view of the cooling suit 1 in Embodiment 1, Figure 2 is a schematic rear view of the cooling suit 1 in Embodiment 1, and Figure 3 is a schematic diagram of the inside of the cooling suit 1 in Embodiment 1 when spread out.

[0013] As shown in Figure 12A, the central axis of the cooling suit 1 (the central axis of the person) when the cooling suit 1 is worn on the person's body is defined as the center line 92. Furthermore, using the cooling suit 1 as a reference point when worn on a person's body, the left side of the center line 92 is defined as the left side, and the right side is defined as the right side. Furthermore, using the cooling suit 1 as a reference point, the side closer to the person's body is defined as the inside, and the side further away from the person's body is defined as the outside. Furthermore, using the cooling suit 1 as a reference point, the head side is defined as the upper side and the foot side as the lower side. Furthermore, the term "human body" encompasses both the naked state (skin only) and the state in which a person is wearing clothes. Furthermore, the term "water" includes, for example, cold water chilled in a refrigerator, as well as water at room temperature (the ambient temperature where people are present).

[0014] As shown in Figure 1, the cooling suit 1 has an outer fabric 2 positioned on the front of the body, an inner fabric 3 positioned on the back of the body, a left-side fabric 4 positioned on the left side of the body, a right-side fabric 5 positioned on the right side of the body, and a zipper 7 positioned in the middle of the outer fabric 2. The cooling suit 1 also has reinforcing lines 6 that reinforce the edges.

[0015] The outer fabric 2 and / or inner fabric 3 have a single first intermediate layer 31 made of nonwoven fabric that absorbs water and vaporizes the absorbed water using body heat. The first intermediate layer 31 is provided across the entire surface of the outer fabric 2 and / or the entire surface of the inner fabric 3. As shown in Figure 2, the second intermediate layer 35 is partially provided on the first intermediate layer 31 in the back fabric 3, around the back area. Alternatively, the second intermediate layer 35 may be partially provided on the first intermediate layer 31 in the front fabric 2. Details of the first intermediate layer 31 and the second intermediate layer 35 will be described later.

[0016] Figure 4A is a schematic cross-sectional view representing section AA in Figure 1, and Figure 4B is a schematic cross-sectional view representing section BB in Figure 1. As shown in Figures 4A and 4B, the crimped portion 11 is the part in which the outer layer 30, the moisture permeability control layer 33, and the inner layer 32 are crimped, joined, or bonded together. The heat-sealed portion 11 encloses the first intermediate layer 31 and the second intermediate layer 35 in the outer fabric 2 and / or inner fabric 3, and is a linear portion where the outer layer 30 and the inner layer 32 are heat-sealed together, forming a continuous line drawn in a single stroke.

[0017] As shown in Figures 1 and 2, the outer fabric 2 has multiple water-retaining sections 13 that hold water. Details of the water-retaining sections 13 will be described later, but each water-retaining section 13 has a hole 10 (black circle) in the center that penetrates the outer fabric 2.

[0018] As shown in Figure 3, similar to the front fabric 2, the back fabric 3 also has a water-retaining section 13 that holds multiple water droplets, a first intermediate layer 31, and a crimped section 11. Furthermore, the first intermediate layer 31 may be enclosed separately inside the front fabric 2 and inside the back fabric 3, or the two separate first intermediate layers 31 may be joined together to form a single layer.

[0019] The reverse side fabric 3 is provided with a water inlet 20 at the top for supplying water to the first intermediate layer 31, and a drain outlet 22 at the bottom for draining the water absorbed by the first intermediate layer 31. Here, "upper part" refers to the area above the halfway point of the cooling suit 1, and "lower part" refers to the area below the halfway point of the cooling suit 1. In Figure 2, the drain opening 22 is positioned at the left edge of the back fabric 3 so that when a person sits on a chair or the like, their body is not pressed against by the drain opening 22. Alternatively, the drain opening 22 may be positioned at the right edge.

[0020] As shown in Figure 1-3, when a person wears the cooling suit 1, the left side fabric 4 and the right side fabric 5 are provided so that the outer fabric 2 and the inner fabric 3 fit snugly to the body. The left side fabric 4 and the right side fabric 5 connect the outer fabric 2 and the inner fabric 3 and are made of a stretchable material such as rubber. The left side fabric 4 and the right side fabric 5 may have multiple holes to improve breathability.

[0021] Next, we will explain the details of each component. (Water inlet and outlet) Figure 2 is a schematic rear view of the cooling suit 1 of Embodiment 1, and Figure 2 shows enlarged views of the water inlet 20 and the drain outlet 22. Based on the state in which the cooling suit 1 is worn, the water inlet 20 has an outer cover 24 positioned far from the body and an inner cover 25 positioned close to the body. The outer cover 24 and the inner cover 25 are in contact in the front-to-back direction, and together they form a sealing section 34 to prevent water from the first intermediate layer 31 from leaking out from the inside.

[0022] The outer cover 24 has a protrusion that can be grasped by hand. The inner surface of the outer cover 24 has a convex portion 26, and the outer surface of the inner cover 25 has a concave portion 27. By pressing the outer cover 24 against the inner cover 25, the convex portion 26 and the concave portion 27 engage, preventing water from leaking out of the first intermediate layer 31.

[0023] The water injected from the water inlet 20 is absorbed by the first intermediate layer 31 of the back fabric 3, and also spreads and is absorbed by the first intermediate layer 31 of the front fabric 2, so that the water spreads across the entire surface of the cooling suit 1.

[0024] Furthermore, the water inlet 20 may be made of hook-and-loop fasteners such as Velcro (registered trademark), waterproof zippers, or waterproof fasteners to prevent water from leaking out of the first intermediate layer 31. Furthermore, the drain port 22 may have the same structure as the water inlet 20, but may be of a different size. Furthermore, the drain port 22 and the water inlet 20 may be provided on the outer fabric 2.

[0025] As shown in Figure 2, the drain port 22 has a structure similar to the cap of a PET bottle (registered trademark) and includes a cap nut 41, a cap bolt 42, and a connecting member 43. The connecting member 43 connects the cap nut 41 and the cap bolt 42 in order to prevent the loss of the cap nut 41. The end of the connecting member 43 on the cap nut 41 side and the cap nut 41 are connected in such a way that the cap nut 41 can rotate relative to the end of the connecting member 43.

[0026] When the cap nut 41 and the cap bolt 42 are brought into contact, and the cap nut 41 is rotated, for example, clockwise, the cap nut 41 is screwed onto the cap bolt 42. The cap nut 41 and the cap bolt 42 are then securely fixed together.

[0027] According to the above embodiment, even if a person wearing the cooling suit 1 sits in a chair with a backrest, such as a car seat, the cap nut 41 and cap bolt 42 are securely fixed, so that the water in the first intermediate layer 31 does not leak out of the drain port 22.

[0028] Furthermore, the drain outlet 22 may be composed of a watertight fastener to prevent water from leaking out of the first intermediate layer 31.

[0029] (Water holding part) In Figures 1 and 2, when water drips from the shoulder of the cooling suit 1 to the lower part of the cooling suit 1, the water holding section 13 holds the water. As shown in Figure 4B, the water-retaining section 13 has a hole 10 that penetrates the outer fabric 2 and / or the inner fabric 3, a compressed section 11 in which the outer layer 30, the moisture permeability control layer 33, and the inner layer 32 are tightly bonded around the hole 10, and a gap 12 located around the compressed section 11 and between the outer layer 30 and the inner layer 32. The water is stored in the void 12 and retained in the water-holding section 13.

[0030] The water-retaining section 13 will be described in detail. The water-holding section 13 is for temporarily storing water. To explain in more detail, when water is supplied from the water inlet 20 to the first intermediate layer 31, the water is temporarily stored in the void 12 of the water holding section 13. In that state, when the water held in the first intermediate layer 31 adjacent to the void 12 vaporizes, the amount of water held in the first intermediate layer 31 decreases. Then, due to capillary action in the first intermediate layer 31, the water stored in the void 12 moves from the void 12 to the first intermediate layer 31 and is absorbed. As more time passes, all the water stored in the void 12 moves to the first intermediate layer 31, and the water in the void 12 disappears.

[0031] (Front fabric and back fabric) As shown in Figure 4A, the outer fabric 2 has a waterproof inner layer 32 positioned close to the body, a breathable outer layer 30 positioned away from the body, a first intermediate layer 31 made of nonwoven fabric positioned above the inner layer 32 that absorbs and stores water, and a breathability control layer 33 positioned between the first intermediate layer 31 and the outer layer 30 that limits the amount of vapor (moisture) released from the first intermediate layer 31 to the outside of the garment 1.

[0032] The material of the inner layer 32 is preferably a waterproof material such as nylon, or a waterproof and breathable material. Furthermore, the material of the inner layer 32 may be treated to prevent static electricity using, for example, hydrophilic polymer or other antistatic yarn.

[0033] The material of the first intermediate layer 31 is a nonwoven fabric, and is preferably a polyurethane moisture-wicking polyester fleece, a technology core polyester fleece, or a fiber containing a polymer mainly composed of sodium polyacrylate and directly spun therefrom. Furthermore, the material of the first intermediate layer 31 may be a polymer absorbent. The material of the first intermediate layer 31 is not limited to the above-mentioned material, as long as it is a material that absorbs water and readily vaporizes the absorbed water.

[0034] The material of the moisture permeability control layer 33 is preferably a material that has both waterproofing properties that prevent water from passing through the first intermediate layer 31 and moisture permeability that allows vapor (moisture) from passing through the first intermediate layer 31. By increasing the thickness of the moisture-permeable control layer 33, the amount of vapor (moisture) from the first intermediate layer 31 that passes through the moisture-permeable control layer 33 to the outside can be reduced. The moisture permeability control layer 33 is preferably made of thermoplastic polyurethane, for example. Thermoplastic polyurethane comes in two types: non-porous film and porous film. Non-porous films are films with few tiny holes (air bubbles). Porous films are films that have many tiny holes (air bubbles). Non-porous films and porous films both have tiny holes (air bubbles). The number of holes (air bubbles) per unit area of ​​a porous film is greater than the number of holes (air bubbles) per unit area of ​​a non-porous film. If the thickness of the non-porous film and the porous film are the same, the porous film will allow more vapor (moisture) from the first intermediate layer 31 to pass through the moisture control layer 33 to the outside.

[0035] As shown in Figures 4A and 4B, two methods for forming a moisture permeability control layer 33 on the surface of the outer layer 30 will be described. The first method involves making the moisture-permeable control layer 33 into a thin film, laminating the film-like moisture-permeable control layer 33 with the surface layer 30, and bonding them together by heat pressing or other means. The second method is as follows: (1) The solution of the moisture permeability control layer 33 is poured into the outer layer 30. (2) Dry the solution in the moisture permeability control layer 33 that has been poured in. (3) Once drying is complete, a moisture permeability control layer 33 is formed on the surface of the outer layer 30.

[0036] As shown in Figure 4A, the cooling suit 1 has a crimped portion 11 where the outer layer 30, the moisture permeability control layer 33, and the inner layer 32 are pressed together, joined, or bonded. There is a gap 12 between the crimped portion 11 and the first intermediate layer 31. In other words, the crimped portion 11 at the outer edge of the cooling suit 1 surrounds the first intermediate layer 31 via the gap 12. The crimped portion 11 at the outer edge of the cooling suit 1 does not have the first intermediate layer 31. Furthermore, the cooling suit 1 may not have the gap 12, and the first intermediate layer 31 and the outer edge crimped portion 11 may be in contact. Furthermore, the reverse side fabric 3 has the same structure and material as the front side fabric 2.

[0037] Next, we will explain the bonding method for the crimped section 11 (three layers: the outer layer 30, the moisture permeability control layer 33, and the inner layer 32) shown in Figures 4A and 4B. As shown in Figures 4A and 4B, when high-frequency welding is performed with the outer layer 30, the moisture permeability control layer 33, and the inner layer 32 stacked together, friction between the moisture permeability control layer 33 and the outer layer 30, and between the moisture permeability control layer 33 and the inner layer 32 generates heat, causing the moisture permeability control layer 33 to melt partially or entirely, thereby bonding the outer layer 30 and the inner layer 32. Furthermore, the bonding method for the crimped portion 11 may be heat welding.

[0038] The material of the outer layer 30 is breathable, and preferably a material that is compatible with the breathability control layer 33, such as nylon or polyester. Furthermore, the material of the outer layer 30 may be cotton or other materials. Furthermore, the material for the outer layer 30 is preferably a breathable material such as 50% nylon jersey and 50% polyurethane. Furthermore, the material of the outer layer 30 may be treated to prevent static electricity using antistatic yarn or the like.

[0039] The material of the outer layer 30 and / or the material of the inner layer 32 may be made of flame-retardant fibers. In addition, the material of the outer layer 30 and / or the material of the inner layer 32 may be treated with flame-retardant processing. Flame-retardant fibers and flame-resistant treated fibers that can be used include Vinal®, polyetherimide (PEI) fibers, Moeny®, Conex®, Super Exter®, Anfra®, Heim®, Protexa® FR, Honoguard®, Brevano®, and Nonex®.

[0040] (First meso-intermediate layer and second meso-intermediate layer) Figure 7A is a schematic front view of the first intermediate layer 31 and the second intermediate layer 35, and Figure 7B is a schematic cross-sectional view of the first intermediate layer 31 and the second intermediate layer 35. As shown in Figures 7A and 7B, the second intermediate layer 35 is partially provided in the first intermediate layer 31 of the outer fabric 2 and / or inner fabric 3, and is located between the outer layer 30, which includes the moisture permeability control layer 33, and the first intermediate layer 31. Furthermore, the material of the second intermediate layer 35 is the same as the material of the first intermediate layer 31. The second intermediate layer 35 may be provided between the inner layer 32 and the first intermediate layer 31.

[0041] The first intermediate layer 31 and the second intermediate layer 35 have an intermediate layer joint 36, and the first intermediate layer 31 and the second intermediate layer 35 are connected at the intermediate layer joint 36. The intermediate layer joint 36 is, for example, a part sewn with thread or the like. In the case of Figure 7A, the intermediate layer joint 36 is formed by fine stitching in a straight line from the right end to the left end of the second intermediate layer 35, in the central part in the vertical direction of the second intermediate layer 35. Therefore, as shown in Figure 7B, when a person wears the cooling suit 1, the intermediate layer joint 36 can store water without allowing the water accumulated between the first intermediate layer 31 and the second intermediate layer 35 above the intermediate layer joint 36, and / or the water absorbed by the first intermediate layer 31 and the second intermediate layer 35, to fall below the intermediate layer joint 36.

[0042] More specifically, as shown in Figure 7B, there is a gap between the second intermediate layer 35 and the outer layer 30, so the second intermediate layer 35 above the intermediate layer joint 36 bulges slightly outward, allowing water to be stored between the first intermediate layer 31 and the second intermediate layer 35. Furthermore, when a person wears the cooling suit 1, the intermediate layer joint 36 can store water without allowing the water absorbed by the first intermediate layer 31 and the second intermediate layer 35 above the intermediate layer joint 36 to fall below the intermediate layer joint 36. Then, as shown in Figure 7A, the stored water falls from the right and / or left side of the intermediate layer joint 36 downwards from the intermediate layer joint 36 and spreads throughout the entire first intermediate layer 31.

[0043] The more the intermediate layer joint 36 is located below the second intermediate layer 35, the more water can be stored. Therefore, the amount of water stored can be controlled by changing the position of the intermediate layer joint 36 in the second intermediate layer 35.

[0044] According to the above embodiment, water can be stored between the first intermediate layer 31 and the second intermediate layer 35 above the intermediate layer joint 36, so that the body can be cooled for a long period of time.

[0045] (Embodiment 2) In Embodiment 1, the intermediate layer joint 36 is located in the center of the second intermediate layer 35, and the first intermediate layer 31 and the second intermediate layer 35 are finely sewn together in a straight line from the right end to the left end of the second intermediate layer 35. Water above the intermediate layer joint 36 is then allowed to fall below the intermediate layer joint 36 from the right and left sides of the intermediate layer joint 36. In Embodiment 2, an intermediate layer opening 37 is provided in the intermediate layer joint 36, and water accumulated between the first intermediate layer 31 and the second intermediate layer 35 above the intermediate layer joint 36 is allowed to fall through the intermediate layer opening 37.

[0046] Figure 8 is a schematic front view of the second intermediate layer 35 in which an intermediate layer opening 37 is provided in the center of the intermediate layer joint 36 in Embodiment 2. As shown in Figure 8, the second intermediate layer 35 has an intermediate layer opening 37 in a part of the central section of the intermediate layer joint 36, by not sewing it. The water accumulated between the first intermediate layer 31 and the second intermediate layer 35 above the intermediate layer joint 36 can be allowed to fall below the intermediate layer joint 36 through one of the intermediate layer openings 37 in the center of the intermediate layer joint 36. As a result, water can be uniformly distributed in the first intermediate layer 31 below the intermediate layer joint 36. Furthermore, as shown in Figure 7A, the second intermediate layer 35 in Figure 8 may allow water accumulated between the first intermediate layer 31 and the second intermediate layer 35 above the intermediate layer joint 36 to fall below the intermediate layer joint 36 through one intermediate layer opening 37 in the center, as well as allowing water to fall downward from the right and / or left side of the intermediate layer joint 36.

[0047] The second intermediate layer 35 is provided with four first intermediate layer fasteners 38 at its four corners, which secure the second intermediate layer 35 to the first intermediate layer 31. The first intermediate layer fastener 38 is, for example, sewn. This prevents the upper end of the second intermediate layer 35 from shifting relative to the first intermediate layer 31 when a person is wearing the cooling suit 1. Furthermore, even if a person holds the cooling suit 1 upside down, it is possible to prevent the lower end of the second intermediate layer 35 from shifting relative to the first intermediate layer 31.

[0048] Figure 9 is a schematic front view of another embodiment in which three intermediate layer openings 37 are provided in the intermediate layer joint 36 of Embodiment 2. As shown in Figure 9, three intermediate layer openings 37 are provided at the intermediate layer joint 36 by partially omitting stitching. The water accumulated between the first intermediate layer 31 and the second intermediate layer 35 above the intermediate layer joint 36 can be allowed to fall below the intermediate layer joint 36 through the three intermediate layer openings 37. As a result, water can be distributed more uniformly in the first intermediate layer 31 below the intermediate layer joint 36 than in the configuration shown in Figure 8. Furthermore, as shown in Figure 7A, the second intermediate layer 35 in Figure 9 may allow water accumulated between the first intermediate layer 31 above the intermediate layer joint 36 and the second intermediate layer 35 to fall below the intermediate layer joint 36 through the three intermediate layer openings 37, as well as allowing water to fall downward from the right and / or left side of the intermediate layer joint 36.

[0049] (Embodiment 3) Embodiment 3 is a configuration in which the first intermediate layer 31 of the outer fabric 2 of the cooling suit 100 does not cover the abdomen but covers the rib cage. Figure 10 is a schematic diagram of the front fabric 2 in Embodiment 3, and Figure 11 is a schematic diagram of the back fabric 3 in Embodiment 3. As shown in Figure 10, the outer fabric 2 has the first intermediate layer 31 covering the rib cage and the mesh covering the abdomen. Therefore, in the cooling suit 100, the first intermediate layer 31 does not cover the abdomen. As shown in Figure 11, the structure of the backing fabric 3 is basically the same as the structure of the backing fabric 3 in Figure 2. The left fabric 4 and the right fabric 5 use a stretchable mesh.

[0050] (Embodiment 4) Figures 12A and 12B are schematic perspective views illustrating the operation of layering the cooling suits 1 and 100 of the present disclosure with the air-conditioned functional suit 50 (also known as the Air-Conditioned Wind God Suit (registered trademark)) in embodiments 1 and 3. Figure 12A shows a person wearing cooling suits 1 and 100, and Figure 12B shows a person wearing an air-conditioned garment 50 over the cooling suits 1 and 100. As described in Japanese Utility Model Publication No. 3-32487 and Japanese Patent Publication No. 6536674, the air-conditioned garment 50 is a garment to which a fan 51 is attached to blow outside air into the inside of the garment, and the outside air evaporates the sweat released from the body, thereby lowering the body temperature. Furthermore, the air-conditioned workwear 50 is also referred to as EF wear or fan-equipped workwear.

[0051] This section explains how to layer the cooling suit 1,100 and the air-conditioned functional suit 50. First, as shown in Figure 12A, the cooling suits 1 and 100, which have already been filled with water, are put on the body and the zippers 7 are fastened. Next, as shown in Figure 12B, the air-conditioned garment 50 is placed over the cooling garments 1 and 100, and the zipper of the air-conditioned garment 50 is fastened. Finally, the fan 51 of the air-conditioned garment 50 is turned on to draw outside air into the garment. The combination of layered cooling garments 1,100 and air-conditioned garment 50 is referred to as a cooling garment set.

[0052] According to the above embodiment, the air-conditioned garment 50 sends outside air to the surface of the cooling garments 1, 100, which promotes the evaporation of water in the cooling garments 1, 100 and allows the body temperature to be lowered quickly. Although the fan 51 was turned on after putting on the air-conditioned garment 50, it is also acceptable to wear the air-conditioned garment 50 with the fan 51 already turned on over the cooling garments 1 and 100.

[0053] Alternatively, the cooling suit 1,100 can be turned inside out (reversed) and worn on the body, and the reversed cooling suit 1,100 can be worn over the air-conditioned garment 50. The process of layering the reversed cooling suit 1, 100 with the air-conditioned suit 50 is the same as in Figure 12B, so the explanation is omitted.

[0054] According to the above embodiment, since the outer layer 30 of the outer fabric 2 and the outer layer 30 of the inner fabric 3 of the cooling suit 1, 100 are positioned close to the body, the water in the first intermediate layer 31 can pass through the outer layer 30 and evaporate, lowering body temperature even without the person sweating. Furthermore, since outside air is supplied to the cooling suit 1, 100 by the air-conditioned suit 50, evaporation of the cooling suit 1, 100 is promoted, and the body temperature can be lowered quickly.

[0055] Furthermore, considering the external design, the cooling suits 1 and 100 may be provided with a water inlet 20 and a drain outlet 22 on the inside. Specifically, the water inlet 20 may be provided on the upper inside of the right or left front fabric 2, or on the upper inside of the back fabric 3. Furthermore, a drain opening 22 may be provided on the lower inside side of the right or left front fabric 2, or on the lower inside side of the back fabric 3.

[0056] According to the above embodiment, the cooling suit 1, 100 has the same water injection and drainage functions as the cooling suit 1, 100 of Embodiment 1, and since the water injection port 20 and drainage port 22 are provided on the inside of the cooling suit 1, 100, it is possible to prevent the external design of the cooling suit 1, 100 from being compromised. Furthermore, since the cooling suits 1,100 are equipped with a water inlet 20 and a drain outlet 22 on the inside, it is possible to prevent the lids of the water inlet 20 or drain outlet 22 from getting caught on something and opening.

[0057] (Embodiment 5) Embodiment 5 is a configuration in which an inner layer 32 having waterproof or breathable and waterproof properties is provided in a position close to the human body, and a breathable control layer 33 (also referred to as the first breathable control layer 33a) is placed on top of (outside of) the inner layer 32. Figure 5A is a schematic cross-sectional view corresponding to the AA cross-section of the cooling suit 1 in Figure 1 in Embodiment 5, and Figure 5B is a schematic cross-sectional view corresponding to the BB cross-section of the cooling suit 1 in Figure 1 in Embodiment 5. As shown in Figure 5A, the outer fabric 2 or inner fabric 3 comprises, in order from closest to the human body, an inner layer 32 that is waterproof or breathable and waterproof, a breathability control layer 33, a first intermediate layer 31, and an outer layer 30 that is waterproof but not breathable. On both sides of the outer fabric 2 or inner fabric 3, there are crimped portions 11 to which the inner layer 32, the breathability control layer 33, and the outer layer 30 are bonded. The outer fabric 2 or inner fabric 3 has a gap 12 between the crimped portion 11 and the first intermediate layer 31.

[0058] Similarly, in Figure 5B, the outer fabric 2 or inner fabric 3 comprises, in order from closest to the human body, an inner layer 32 that is waterproof or breathable and waterproof, a breathability control layer 33, a first intermediate layer 31, and an outer layer 30 that is waterproof but not breathable. The outer fabric 2 or the inner fabric 3 has an inner layer 32, a moisture permeability control layer 33, and holes 10 that penetrate the outer layer 30. The outer fabric 2 or the inner fabric 3 has a gap 12 between the heat-sealed portion 11 and the first intermediate layer 31. The outer fabric 2 or the inner fabric 3 has a crimped portion 11 where the inner layer 32, the moisture permeability control layer 33, and the outer layer 30 are bonded together, surrounding the hole 10. The water-retaining portion 13 is formed by the hole 10, the crimped portion 11, and the gap 12.

[0059] According to the above embodiment, in the outer fabric 2 and / or inner fabric 3 of the cooling suit 1, 100, the inner layer 32 having waterproof or breathable and waterproof properties is positioned close to the body. Therefore, when the water in the first intermediate layer 31 evaporates, the evaporated water passes through the inner layer 32 and comes into contact with the person's body. As a result, the person's body temperature can be lowered without sweating as the water that comes into contact with the person's body evaporates.

[0060] Figures 6A and 6B represent different embodiments from Figures 5A and 5B, respectively. Figure 6A is another schematic cross-sectional view of the cooling suit 1 in Embodiment 1, corresponding to cross-section AA in Figure 1, and Figure 6B is another schematic cross-sectional view of the cooling suit 1 in Embodiment 1, corresponding to cross-section BB in Figure 1. As shown in Figure 6A, the outer fabric 2 or inner fabric 3 comprises, in order from closest to the human body, an inner layer 32 that is waterproof or breathable and waterproof, a first breathable control layer 33a, a first intermediate layer 31, a second breathable control layer 33b, and an outer layer 30 that is waterproof or breathable and waterproof. On both sides of the outer fabric 2 or inner fabric 3, there are crimping sections 11 to which the inner layer 32, the first breathable control layer 33a, the second breathable control layer 33b, and the outer layer 30 are bonded. Furthermore, the first moisture-permeable control layer 33a and the second moisture-permeable control layer 33b can be made from the same material as the moisture-permeable control layer 33 described in Embodiment 1. The outer fabric 2 or the inner fabric 3 has a gap 12 between the heat-sealed portion 11 and the first intermediate layer 31.

[0061] Similarly, in Figure 6B, the outer fabric 2 or inner fabric 3 comprises, in order from closest to the human body, an inner layer 32 that is waterproof or breathable and waterproof, a first breathable control layer 33a, a first intermediate layer 31, a second breathable control layer 33b, and an outer layer 30 that is waterproof or breathable and waterproof (both sides of Figure 6B). The outer fabric 2 or the inner fabric 3 has holes 10 that penetrate the inner layer 32, the first moisture permeability control layer 33a, the second moisture permeability control layer 33b, and the outer layer 30. The outer fabric 2 or the inner fabric 3 has a gap 12 between the heat-sealed portion 11 and the first intermediate layer 31. The outer fabric 2 or the inner fabric 3 has a crimped portion 11 where the inner layer 32, the first moisture permeability control layer 33a, the second moisture permeability control layer 33b, and the outer layer 30 are bonded together, surrounding the hole 10. The water-retaining portion 13 is formed by the hole 10, the crimped portion 11, and the gap 12.

[0062] According to the above embodiment, in the outer fabric 2 and / or inner fabric 3 of the cooling suit 1, 100, the inner layer 32, which is breathable and waterproof, is positioned close to the body. Therefore, when the water in the first intermediate layer 31 evaporates, the evaporated water passes through the inner layer 32 and comes into contact with the person's body. As a result, the person's body temperature can be lowered without sweating as the water that comes into contact with the person's body evaporates. Furthermore, when the water in the first intermediate layer 31 evaporates, the evaporated water passes through the breathable and waterproof outer layer 30 and is discharged to the outside. As a result, body temperature can be further lowered.

[0063] (Embodiment 6) Embodiment 6 is a configuration in which the water in the first intermediate layer 31 is directly cooled by the coolant 72 in the cooling bag 70. Figure 13A is a schematic diagram of the cooling suit 200 in Embodiment 6 when unfolded, showing a person viewing the cooling suit 200 from the outside; Figure 13B is a schematic diagram of the cooling suit 200 in Embodiment 6 when unfolded, showing a person viewing the cooling suit 200 from the inside; and Figure 14A is a schematic cross-sectional view of the periphery of a cooling bag 70 in one embodiment of Embodiment 6.

[0064] As shown in Figures 13A and 13B, in the cooling suit 200, the cooling bag 70 is positioned at the lower inside of the back fabric 3. As shown in Figure 14A, the outer fabric 2 and / or inner fabric 3 consist of an inner layer 32, a first moisture-permeable control layer 33a, a first intermediate layer 31, a second moisture-permeable control layer 33b, and an outer layer 30, in order from closest to the human body. The main components of these are the same as those in Figure 6A. The difference from Figure 6A is that the moisture permeability (water vapor permeability) of the first moisture control layer 33a is higher than that of the second moisture control layer 33b. In other words, the amount of water vapor in the first intermediate layer 31 passing through the first moisture-permeable control layer 33a is greater than the amount of water vapor in the first intermediate layer 31 passing through the second moisture-permeable control layer 33b. Therefore, most of the water vapor vaporized from the first intermediate layer 31 passes through the first moisture permeability control layer 33a, then through the inner layer 32, and reaches the space inside the outer fabric 2 and / or inner fabric 3. Furthermore, the moisture permeability of the second moisture permeability control layer 33b and the moisture permeability of the first moisture permeability control layer 33a may be equal. Moisture permeability (water vapor permeability) is measured, for example, by JIS L 1099:2012 A-1 method, B-1 method, etc.

[0065] The cooling bag 70 is positioned between the moisture-permeable control layer 33 on the inner layer 32 side and the first intermediate layer 31, and is in direct contact with the first intermediate layer 31. The cooling bag 70 holds ice packs, cold water poured from a PET bottle 76, etc.

[0066] The cooling bag 70 is provided with a cooling bag opening / closing section 71 to house the coolant 72 and to prevent the coolant 72 from spilling out of the cooling bag 70. The opening and closing section 71 of the cooling bag is preferably, for example, a waterproof fastener or a water-resistant fastener.

[0067] Figure 14B is a schematic cross-sectional view of the periphery of a cooling bag 70 in another embodiment of Embodiment 6. As shown in Figure 14B, the cooling bag 70 is positioned between the moisture-permeable control layer 33 on the outer layer 30 side and the first intermediate layer 31, and is in direct contact with the first intermediate layer 31.

[0068] According to the above embodiment, the water in the first intermediate layer 31 is cooled by the coolant 72 of the cooling bag 70, so the body can be cooled for a long period of time. Furthermore, since the water in the first intermediate layer 31 accumulates at the bottom of the back fabric 3 due to gravity, the cooling suit 200 can cool the body for an extended period of time by cooling the water accumulated at the bottom of the back fabric 3 with the coolant 72 in the cooling bag 70 located at the bottom of the back fabric 3.

[0069] In addition, while the water-retaining portion 13 in Figure 2 was circular, in Embodiment 6, the water-retaining portion 13 is rectangular in order to prevent stuffiness. Furthermore, since the water-retaining part 13 is rectangular (including those with rounded corners), it has four corners. The water-retaining part 13 can also be polygonal. However, due to a person's movements, the cooling suit 200 is pulled in one of the following directions: left, right, outward, inward, or a combination thereof, causing tears to occur at the corners. Therefore, it is preferable to have fewer corners in the water-retaining section 13. Furthermore, the water-holding portion 13 only needs to be horizontally elongated, and its shape is not particularly limited. The cooling bag 70 may, for example, be provided on the outer fabric 2. The location of the cooling bag 70 is not particularly limited, as long as it is in direct contact with the first intermediate layer 31. Furthermore, as shown in Figures 14A and 14B, the coolant 72 may be prepared by pouring cold water or water from a PET bottle 76 after placing the cooling pack in the cooling bag 70, and then using the mixture as the coolant 72. This increases the area in which the cooling bag 70 is in direct contact with the first intermediate layer 31. Furthermore, the other components of Embodiment 6 are the same as those of Embodiment 1.

[0070] (Another form of Embodiment 6) In Figures 14A and 14B, the cooling suit 200 has a cooling bag 70. Another embodiment of Embodiment 6 is one in which the cooling bag 70 is not used, and the cooling suit 200 has only the cooling bag opening / closing part 71. Specifically, the inner layer 32 and first moisture permeability control layer 33a of the outer fabric 2 and / or inner fabric 3, and the outer layer 30 and second moisture permeability control layer 33b are provided with a cooling bag opening / closing section 71. A person opens the opening 71 of the cooling bag, puts in a cooling agent, cold water, or a mixture thereof (hereinafter referred to as the cooling agent) through the opening 71 of the cooling bag, and then closes the opening 71 of the cooling bag. The cooling agent then accumulates at the bottom of the outer fabric 2 and / or the inner fabric 3.

[0071] Normally, cold water is injected through the water inlet 20 at the top of the back fabric 3, but as time passes, the water that has dripped down to the bottom of the back fabric 3 becomes warm, so the warmed water is cooled with a coolant. The coolant comes into direct contact with the first intermediate layer 31, cooling the water in the first intermediate layer 31 and simultaneously cooling the body.

[0072] Additionally, by holding the lower end of the cooling suit 200 and turning it upside down, the water cooled by the coolant can be distributed throughout the entire cooling suit 200. The cooling agent is located on the inner layer of the lower part of the outer fabric 2 and / or inner fabric 3, closer to the skin. This allows the coolness of the cooling agent to transfer to the skin-facing outer fabric 2 and / or inner fabric 3, resulting in a cooling effect on the part of the body that is in contact with the cooling agent.

[0073] (Embodiment 7) Embodiment 7 is a configuration in which a first blower fan 110 is provided on the cooling suit 250. Figure 15 is a schematic front view of one embodiment of the cooling suit 250 in Embodiment 7, Figure 16 is a schematic rear view of one embodiment of the cooling suit 250 in Embodiment 7, and Figure 20 is a schematic cross-sectional view of the area around the first blower fan 110 in Embodiment 7. As shown in Figure 15, the first blower fan 110 is provided on the lower right and left sides of the outer fabric 2 of the cooling suit 250, and as shown in Figure 16, the first blower fan 110 is provided on the lower right side of the inner fabric 3 of the cooling suit 250. Furthermore, the first blower fan 110 may be located in the center of the back fabric 3. The front fabric 2 and the back fabric 3 are provided with reinforcing members 105 having a certain thickness for attaching the first blower fan 110.

[0074] As shown in Figure 20, the first blower fan 110 comprises a blower fan body 113 which integrates an outer case 111 and an inner case 112, and a ring 114. The outer case 111 is equipped with a motor 115 and a fan 116. A first engaging portion 117 is provided on the outer circumference of the outer case 111, and a second engaging portion 118 is provided on the inner circumference of the ring 114.

[0075] The front fabric 2 and / or back fabric 3 are provided with a fan opening 150 for attaching the first fan 110. The blower fan body 113 is inserted into the blower fan opening 150, and a ring 114 is inserted into the inserted blower fan body 113. By rotating the ring 114, the first blower fan 110 is fixed to the cooling suit 250. At this time, the first engaging portion 117 of the outer case 111 and the second engaging portion 118 of the ring 114 engage with the cooling suit 250 in between.

[0076] A fan spacer 120 is provided on the surface of the inner case 112 that is close to the body 80. The first blower fan 110 is fixed to the cooling suit 250, and when the fan 116 rotates, the air between the cooling suit 250 and the body 80 is discharged to the outside of the first blower fan 110. As a result, the amount of air inside the cooling suit 250 decreases, and the cooling suit 250 becomes more tightly fitted to the body 80. However, the fan spacer 120 creates a gap between the first blower fan 110 and the body 80, preventing the inner case 112 (cooling suit 250) of the first blower fan 110 from being in close contact with the body 80. This allows the air between the cooling suit 250 and the body 80 to be expelled to the outside of the first blower fan 110.

[0077] Furthermore, when the fan 116 fixed to the cooling suit 250 rotates, the pressure between the cooling suit 250 and the body 80 becomes negative relative to the pressure outside the cooling suit 250 (hereinafter simply referred to as atmospheric pressure). In a negative pressure environment, the vaporized water vapor in the first intermediate layer 31 passes through the moisture-permeable control layer 33, then through the moisture-permeable inner layer 32, and reaches the space between the inner layer 32 and the body 80. The water vapor then adheres to the body 80. The water vapor adhering to body 80 temporarily turns into water, but at the temperature of body 80, the water vaporizes and turns back into water vapor. The heat of vaporization from this process can cool body 80. Then, the vaporized water vapor between the cooling suit 250 and the body 80 is discharged to the outside of the first blower fan 110 (cooling suit 250).

[0078] Furthermore, since the space between the cooling suit 250 and the body 80 becomes a negative pressure environment, the left fabric 4 and the right fabric 5 should preferably be made of a stretch material with poor breathability.

[0079] According to the above embodiment, the first blower fan 110 creates a negative pressure in the space between the cooling suit 250 and the body 80 relative to the atmospheric pressure, and the vaporized water vapor from the first intermediate layer 31 is drawn into the space between the cooling suit 250 and the body 80, thereby cooling the body.

[0080] Figure 17 is a schematic front view of another embodiment of the cooling suit 250 in Embodiment 7, and Figure 18 is a schematic rear view of another embodiment of the cooling suit 250 in Embodiment 7. The cooling suit 250 has a first blower fan 110 on the right and left central parts of the outer fabric 2, and two first blower fans 110 on the approximate center (back part) of the inner fabric 3. Furthermore, these first blower fans 110 adjust the direction of the fan blades 116 so that the air inside the cooling suit 250 is expelled to the outside of the cooling suit 250.

[0081] According to the above embodiment, since the first blower fan 110 is provided in the central part of the right and left sides of the outer fabric 2 and / or in the approximate central part (back part) of the inner fabric 3, water vapor between the inner layer 32 (cooling suit 250) and the body 80 can be uniformly discharged. Furthermore, the above embodiment can cool the back.

[0082] Figure 19 is a schematic side view of yet another embodiment of the cooling suit 250 in Embodiment 7. As shown in Figure 19, the first blower fan 110 is installed under the armpits of the left fabric 4 and the right fabric 5. According to the above embodiment, the armpits, which are more sensitive to cold, can be cooled. In Embodiment 7, the first blower fan 110 expelled the air inside the cooling suit 250 to the outside of the cooling suit 250, but conversely, it may also draw outside air into the cooling suit 250. Furthermore, the first blower fan 110 may be configured such that the outer case 111 and the inner case 112 are separate components. Furthermore, the other components of Embodiment 7 are the same as those of Embodiment 1.

[0083] (Embodiment 8) Embodiment 8 is a configuration in which a second blower fan 130, whose airflow direction can be freely changed, is provided on the cooling suit 300. Figure 21 is a schematic rear view of the cooling suit 300 in Embodiment 8. As shown in Figure 21, three second air blowers 130 are provided on the back fabric 3 near the neck and shoulders. Each of the three second blower fans 130 has a blade 131, and by changing the direction of the blade 131, the direction of the air discharged from the second blower fan 130 can be changed. A person can move the blades 131 to change their direction and direct airflow to their neck, head, etc. This allows the body to be cooled not only by the cooling suit 300, but also by the second blower fan 130 to cool the neck, head, etc. The shape of the second blower fan 130 is preferably roughly rectangular in order to reduce the installation area. The fan 116 of the second blower fan 130 is preferably a fan with a long longitudinal length, such as a cross-flow fan. Furthermore, these second blower fans 130 adjust the direction of the fan blades 116 so that the air inside the cooling suit 250 is expelled to the outside of the cooling suit 250. Alternatively, a first blower fan 110 may be provided at the bottom of the inner fabric 3 of the cooling suit 300, and a fan 116 may be provided to draw outside air into the inside of the cooling suit 300. In this case, the first blower fan 110 draws in air from the lower part of the inner fabric 3, and the second blower fan 130 expels it to the outside of the cooling suit 300. This allows the air to flow smoothly from the lower part to the upper part of the inner fabric 3, thus cooling the body. Furthermore, the other components of Embodiment 8 are the same as those of Embodiment 7.

[0084] (Embodiment 9) Embodiment 9 is a configuration in which a third blower fan 140 that blows air to the side is provided on the cooling suit 350. Figure 22 is a schematic side view of the cooling suit 350 in Embodiment 9. As shown in Figure 22, the third blower fan 140 is provided on the left fabric 4 and the right fabric 5. The third blower fan 140 includes a sirocco fan 141, a motor 142, and a third blower fan cover 143. The third blower fan cover 143 has an exhaust port (not shown) at its top. The sirocco fan 141 draws in air between the body 80 and the cooling suit 350 in a direction perpendicular to the center line 92 (Figure 12A), changes the direction of this air to be parallel to the center line 92 (90 degrees), and directs this air to the sides.

[0085] According to the above embodiment, not only is the body cooled by the cooling suit 350, but the armpits can also be cooled by the third blower fan 140. Furthermore, the third blower fan 140 adjusts the direction of the fan blades 116 so that the air inside the cooling suit 250 is expelled to the outside of the cooling suit 250. Furthermore, the other configurations of Embodiment 9 are the same as those in Figure 19.

[0086] (Embodiment 10) Embodiment 10 is a configuration in which a shoulder portion void 184a is provided in the first intermediate layer 31 at the shoulder. Figure 23 is a schematic diagram of the cooling suit 400 having a shoulder gap 184a in Embodiment 10, spread out, and shows a person viewing the cooling suit 400 from the outside. Figure 24 is a schematic diagram of the cooling suit 400 having a shoulder gap 184b in Embodiment 10, spread out, and shows a person viewing the cooling suit 400 from the outside. In Figures 23 and 24, the shoulder ridge 180 is the ridge that forms on the shoulder when a person wears the cooling suit 400. The area below the shoulder ridge line 180 is the reverse fabric 3, the area to the right and above the shoulder ridge line 180 is the right side of the front fabric 2, and the area to the left and above the shoulder ridge line 180 is the left side of the front fabric 2.

[0087] When the cooling suit 400 is attached to the body 80, and water is supplied from the water inlet 20 on the back fabric 3, the supplied water accumulates at the bottom of the back fabric 3. Now, let's consider a case where, hypothetically, in the shoulder area, there is no shoulder gap 184a in Embodiment 10, and the first intermediate layer 31 is connected from the back fabric 3 to the right side and left side of the front fabric 2. By holding down the lower part of the back fabric 3 with one hand and moving the hand to the upper part of the back fabric 3, an attempt is made to supply the water accumulated at the bottom of the back fabric 3 to the right side and left side of the front fabric 2. However, at the shoulders, the right side of the outer fabric 2, the inner fabric 3, and the left side of the outer fabric 2 are all pulled downwards by the weight of the cooling suit 400, resulting in a compressed state. In that state, water has difficulty passing from the back fabric 3 to the right side of the front fabric 2 and to the left side of the front fabric 2.

[0088] Therefore, the cooling suit 400 of Embodiment 10 has a shoulder portion gap 184a, which is a rectangular space obtained by partially removing the first intermediate layer 31 at the shoulder.

[0089] According to the above embodiment, the shoulder gap 184a allows water moving from the back fabric 3 to the left fabric 4 and from the back fabric 3 to the right fabric 5 to easily pass through the shoulder, and the water can be distributed uniformly throughout the cooling suit 400.

[0090] Furthermore, as shown in Figure 24, the cooling suit 400 has shoulder gaps 184b. Shoulder gap 184b is obtained by completely removing the first intermediate layer 31 along the shoulder ridge 180 at the shoulder. Therefore, the left side of the outer fabric 2 has a left first intermediate layer 183a, the right side of the outer fabric 2 has a right first intermediate layer 183b, and the back fabric 3 has a back first intermediate layer 183c. The left first intermediate layer 183a, the right first intermediate layer 183b, and the back first intermediate layer 183c are all separated.

[0091] According to the above embodiment, the shoulder gap 184b allows water moving from the back fabric 3 to the right and left sides of the front fabric 2 to pass more easily through the shoulder, enabling uniform distribution of water throughout the cooling suit 400.

[0092] (Embodiment 11) In Embodiment 1, the outer fabric 2 and the left mesh fabric 4, and the outer fabric 2 and the right mesh fabric 5 are separate components. On the other hand, in the cooling suit 430 of embodiment 11, the left chest area of ​​the outer fabric 2 and the left fabric 4 are integrally constructed. Furthermore, the cooling suit 430 is integrally constructed with the right chest area of ​​the outer fabric 2 and the right fabric 5.

[0093] As shown in Figure 25, the cooling suit 430 has a back fabric 3 positioned on the rear (back) side of the body 80, a left chest side fabric 204 positioned on the left side of the body 80 (right side when viewed from the front), and a right chest side fabric 205 positioned on the right side of the body 80 (left side when viewed from the front). The cooling suit 430 is constructed by connecting the right side chest fabric 205, the back fabric 3, and the left side chest fabric 204 in that order. As shown in Figure 26, the right side chest fabric 205 and the back fabric 3, and the back fabric 3 and the left side chest fabric 204 are connected by a connecting member 170 made of a stretchable material that is non-breathable or has very little breathability. As shown in Figure 25, a zipper 7 is provided between the right side chest fabric 205 and the left side chest fabric 204, connecting the two. Furthermore, the cooling suit 430 has reinforcing lines 6 that reinforce its outer edge.

[0094] The left side chest fabric 204 has a left front fabric 204a at the top, a left side fabric 204b at the lower left side (side area), and a pocket fabric 60 at the lower right side (abdominal area). The pocket fabric 60 has pockets 61 on the outside and / or inside. The left chest side fabric 204 and the pocket fabric 60 are sewn together at the seam 62.

[0095] The interior of the left front fabric 204a and the left side fabric 204b is connected by a single left intermediate layer 183a, which will be described later. On the other hand, the left pocket fabric 60 does not have a left intermediate layer 183a, and there is no connection between the left pocket fabric 60 and the left front fabric 204a, nor between the left pocket fabric 60 and the left side fabric 204b. Here, the chest area visible when a person observes the left side of the outer fabric 2 from the front is defined as the left outer fabric 204a. The left side fabric 204b is the side area other than the left outer fabric 204a and the right pocket fabric 60.

[0096] The right side chest fabric 205 similarly has a right front fabric 205a at the top, a right side fabric 205b at the bottom right (side area), and a pocket fabric 60 at the bottom left (abdominal area) similar to the left side chest fabric 204. The right side chest fabric 205 and the pocket fabric 60 are sewn together at the seam 62.

[0097] The interior of the right front fabric 205a and the right side fabric 205b is connected by a single right intermediate layer 183b. On the other hand, the right pocket fabric 60 does not have a right intermediate layer 183b, and the inside of the right pocket fabric 60 and the right outer fabric 205a, and the inside of the right pocket fabric 60 and the right side fabric 205b are not connected. The pocket fabric 60 on the right side does not have the first intermediate layer 31. Here, the chest area visible when a person observes the right side of the chest fabric 205 from the front is defined as the right side outer fabric 205a. The right side fabric 205b is the side area other than the right side outer fabric 205a and the right pocket fabric 60.

[0098] The reverse fabric 3 contains one reverse intermediate layer 183c inside.

[0099] The moisture permeability of the first moisture permeability control layer 33a of the cooling suit 430 is higher than that of the second moisture permeability control layer 33b. In other words, the amount of water vapor in the first intermediate layer 31 passing through the first moisture-permeable control layer 33a is greater than the amount of water vapor in the first intermediate layer 31 passing through the second moisture-permeable control layer 33b. As a result, most of the water vapor released from the first intermediate layer 31 passes through the first moisture permeability control layer 33a, and then through the inner layer 32, reaching the space between the cooling suit 430 and the body 80.

[0100] According to the above embodiment, water vapor released from the first intermediate layer 31 is taken into the cooling suit 430 and brought into contact with the body 80. The water vapor that comes into contact with the body 80 turns into water and adheres to the body 80. The water adhering to the body 80 vaporizes and turns into water vapor, thereby cooling the body 80. The water vapor is discharged to the outside of the cooling suit 430 from the neck and sides of the cooling suit 430.

[0101] As shown in Figure 25-26, the holes 10 in the cooling suit 430 are located at the top of the cooling suit 430. In outdoor locations with strong sunlight, the outside air temperature at the chest and back is lower than the outside air temperature at the waist. The cooling suit 430 can improve its ability to cool the body 80 by drawing in low-temperature outside air from the chest and back, which are higher than the waist.

[0102] (Embodiment 12) Embodiment 12 is a configuration that makes it easier to take in more outside air into the inside of the cooling suit 450. Figure 27 is a schematic diagram showing the inside of the cooling suit 450 in Embodiment 12.

[0103] (1) Neck exhaust port The reinforcing line 6 at the neck of the inner fabric 3 may be in close contact with the body 80, which may prevent the water vapor inside the cooling suit 450 from being properly expelled from the neck. Therefore, as shown in Figure 27, multiple neck exhaust protrusions 251 that extend towards the body 80 are provided at intervals along the reinforcing line 6 of the neck. The neck exhaust protrusion 251 is made of a material such as rubber, woven fabric, or nonwoven fabric, and the neck exhaust protrusion 251 and the neck reinforcement line 6 are joined by sewing, welding, or adhesive.

[0104] A space, the neck exhaust recess 252, is provided between adjacent neck exhaust protrusions 251. This neck exhaust recess 252 becomes the neck exhaust port 255. Since the neck exhaust port 255 is the gap between the body 80 and the reinforcing line 6, water vapor inside the cooling suit 450 can be discharged from the neck area.

[0105] Alternatively, the reinforcing line 6 may be partially removed to create a neck exhaust recess 252, which can then be used as a neck exhaust port 255.

[0106] (2) Third intermediate layer Furthermore, embodiment 12 has a third intermediate layer 281. As shown in Figure 27, a third intermediate layer 281 is provided on the upper part of the left side fabric 204a and the right side fabric 205b, and is fixed to the first intermediate layer 31. On the right side of Figure 27, an enlarged view of the cross-section (CC cross-section) of the first intermediate layer 31 and the third intermediate layer 281 is shown.

[0107] When water is supplied to the first intermediate layer 31 from the water inlet 20 of the left front fabric 204a, the water falls to the bottom of the left front fabric 204a and then to the bottom of the left side fabric 204b. At this time, water does not easily spread to the upper part of the left side fabric 204b. Therefore, a third intermediate layer 281 is provided on the upper or lower surface of the first intermediate layer 31 at the top of the left side fabric 204b, and the capillary action of the third intermediate layer 281 causes water to rise to the top of the left side fabric 204b, allowing the water to spread throughout the top of the left side fabric 204b (enlarged view of the lower right of Figure 27).

[0108] At the upper and / or lower third intermediate layer joint 282 of the third intermediate layer 281, the third intermediate layer 281 is fixed to the first intermediate layer 31. The third intermediate layer joint 282 is the area where the first intermediate layer 31 and the third intermediate layer 281 are joined by sewing, bonding, or other means.

[0109] According to the above embodiment, the third intermediate layer 281, through capillary action of the third intermediate layer 281, causes the water in the first intermediate layer 31 to rise from the middle to the upper part of the left side fabric 204b, and the water in the first intermediate layer 31 can spread to the upper part of the left side fabric 204b. As a result, the upper part of the left side fabric 204b can be cooled. Furthermore, the third intermediate layer 281 allows the right side fabric 205b to perform the same function and effect as the left side fabric 204b.

[0110] (Embodiment 13) Embodiment 11 has a left first intermediate layer 183a, a right first intermediate layer 183b, and a back first intermediate layer 183c, and has three outer edge crimping portions 11a surrounding each of the left first intermediate layer 183a, the right first intermediate layer 183b, and the back first intermediate layer 183c. On the other hand, the cooling suit 500 of embodiment 13 has a continuous outer edge crimping portion 11a at the outer edges of the left chest side fabric 204, the right chest side fabric 205, and the back fabric 3. Figure 28 is a schematic front view of the cooling suit 500 in Embodiment 13, and Figure 29 is a schematic rear view of the cooling suit 500 in Embodiment 13.

[0111] Embodiment 13 includes a shoulder gap 184b in the shoulder, which is a space without the first intermediate layer 31. The shoulder gap 184b provides space between the left first intermediate layer 183a and the posterior first intermediate layer 183c, and between the right first intermediate layer 183b and the posterior first intermediate layer 183c, completely separating the left first intermediate layer 183a from the posterior first intermediate layer 183c, and between the right first intermediate layer 183b from the posterior first intermediate layer 183c. Furthermore, the left first intermediate layer 183a and the back first intermediate layer 183c, and the right first intermediate layer 183b and the back first intermediate layer 183c may be partially connected.

[0112] According to the above embodiment, the shoulder gap 184b allows water moving from the inner fabric 3 to the left side chest fabric 204 and from the inner fabric 3 to the right side chest fabric 205 to easily pass through the shoulder, and the water can be distributed uniformly throughout the cooling suit 500. In particular, the above effect is achieved when the cooling suit 500 in Figure 28 lacks water inlets 20 on the left chest side fabric 204 and the right chest side fabric 205, and only has water inlets 20 on the back fabric 3.

[0113] Furthermore, the power for the first blower fan 110, the second blower fan 130, and the third blower fan 140 is supplied from a power source such as a mobile battery via a power cord such as Type-C. Furthermore, the first blower fan 110, the second blower fan 130, and the third blower fan 140 may be battery-integrated and without power cords.

[0114] Furthermore, while the second blower fan 130 and the third blower fan 140 expelled the air inside the cooling suits 300 and 350 to the outside of the cooling suit 250, they may also draw outside air into the cooling suit 250.

[0115] Furthermore, it is preferable that all or part of the outer fabric 2 and inner fabric 3 of the cooling suits 1, 100, 200, 250, 300, 350, 400, 430, 450, and 500 of Embodiments 1 to 13 are treated with antibacterial and deodorizing processing or antibacterial and deodorizing processing.

[0116] In Embodiment 1, the outer fabric 2 and the inner fabric 3 have four layers: an outer layer 30, a moisture permeability control layer 33, a first intermediate layer 31, and an inner layer 32. However, these four layers may be present in only one of the outer fabric 2 or the inner fabric 3. For example, if the back fabric 3 has the four layers, the perimeter of the back fabric 3 has a heat-sealed portion 11, the first intermediate layer 31 is surrounded by the heat-sealed portion 11, and the inside of the heat-sealed portion 11 has the four layers. Furthermore, it is conceivable that the outer fabric 2 is composed almost entirely of mesh, and that the outer fabric 2 does not have the aforementioned four layers.

[0117] The mesh coarseness of the outer fabric 2 is equivalent to that of the left fabric 4 or the right fabric 5. However, the mesh coarseness of the outer fabric 2 may be coarser or finer than that of the left fabric 4 or the right fabric 5.

[0118] According to the above embodiment, since the outer fabric 2 or the inner fabric 3 is made of mesh, sweat evaporating from the body can be expelled through the mesh, thus reducing stuffiness caused by sweat. In addition, since sweat does not easily remain on the mesh, the mesh is less likely to retain sweat odor. Furthermore, since water is supplied to the first intermediate layer 31 only through either the outer fabric 2 or the inner fabric 3, the amount of water injected can be reduced, thereby reducing the weight of the cooling suit 1,100. The effects described above are particularly effective during hot periods such as summer. Furthermore, the outer fabric 2 may have the four layers, and almost the entire inner fabric 3 may be made of mesh.

[0119] In Embodiment 1, the left fabric 4 and the right fabric 5 are made of stretchable material, but the stretchable material may be provided with an adjuster to adjust its length. Alternatively, the left fabric 4 and the right fabric 5 may be made of non-stretchable material, and an adjuster may be provided instead.

[0120] Alternatively, the water inlet 20 in Figure 2 may be constructed using the cap of the drain outlet 22 in Figure 2. Alternatively, the drain port 22 in Figure 2 may be configured as the water inlet 21 in Figure 2.

[0121] Furthermore, in Embodiment 1, an embodiment was described in which the material of the inner layer 32 and / or the material of the outer layer 30 are treated to prevent static electricity by using antistatic yarn or the like. However, this disclosure may also include the following embodiments, in which the material of the inner layer 32 and / or the material of the outer layer 30 does not use antistatic yarn or the like. This embodiment involves using spin tape with an antistatic (anti-static) effect. The aforementioned spin tape is made by kneading a conductive material into the fibers of a conductive thread. The spin tape is used by sewing it to the front and / or back surfaces of the garment. Alternatively, the spin tape may be attached to the front and / or back surfaces of the garment by adhesive, bonding, welding, or other means. For example, the spin tape can be "STA-GUARD SPIN TAPE" manufactured by Tokai Thermo Co., Ltd. Furthermore, for the spin tape, for example, "STC60" manufactured by SHINDO Co., Ltd. can be used.

[0122] The spin tape is provided at any location on the cooling suit, such as the shoulder area, armpit area, or side of the cooling suit.

[0123] In Embodiment 4 (Figures 12A and 12B), the cooling suit 1 and the air-conditioned garment 50 were worn together, but the cooling suit 1 may be worn together with the following garments. In this case, the garments are worn on the outside of the cooling suit 1. The clothing in question includes blousons, jackets, work clothes, suits, polo shirts, dress shirts, overalls, white coats (doctor's coats), chef's coats, kimonos, firefighter uniforms, and mascot costumes. Alternatively, as another form of layering, the garment may be placed inside the cooling suits 1, 100.

[0124] Furthermore, the above-mentioned invention can be replaced or combined, as long as no contradiction arises.
