Description
[Technical Field]
[0001] The present invention relates to cooling clothing that utilizes the heat of vaporization of liquid such as water, and a cooling clothing system that uses the same. [Background technology]
[0002] As a cooling device that utilizes the heat of vaporization of liquids such as water, for example, Patent Document 1 below proposes a cooling jacket for use with humans, livestock such as horses, cows, and pigs, or pet animals such as dogs. Specifically, (0013) of Patent Document 1 states the following: "The cooling device 1 shown in Fig. 1 comprises a cooling-to-touch fabric 2 that can be brought into contact with an object and absorb heat from the object, a highly absorbent material 3 that can retain moisture so as to transfer the heat absorbed by the cooling-to-touch fabric 2 to the outside, and a vaporization heat diffusion material 4 made of double raschel knit that diffuses the heat of vaporization from the highly absorbent material 3; the cooling-to-touch fabric 2, highly absorbent material 3, and vaporization heat diffusion material 4 are formed into sheets to form a three-layer structure." [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Japanese Patent Publication No. 2020-78251 Summary of the Invention [Problem to be solved by the invention]
[0004] In the above-mentioned conventional example, as described in (0021) thereof, the contact body, which is a human B or an animal A, is brought into contact with a cool-to-the-touch fabric 2 with good thermal conductivity to absorb heat, and the highly absorbent material 3 in the middle layer is made to absorb and retain moisture, and the heat absorbed by the cool-to-the-touch fabric 2 is transferred to the highly absorbent material 3, and the contact body A, B is cooled by the cooling effect of the heat absorption (latent heat) action caused by the evaporation of moisture in the highly absorbent material 3, and the cooling duration corresponding to the water capacity of the highly absorbent material 3 is ensured. Furthermore, the heat of vaporization from the highly absorbent material 3 is transferred to the heat of vaporization diffusion material 4 made of double raschel knitting on the outside thereof, and the heat of vaporization is dissipated through the air layer 4e in the double raschel knitting. As a result, even in an environment without refrigeration equipment, the cooling effect can be maintained for a long period of time simply by absorbing moisture into the highly absorbent material 3.
[0005] In other words, this conventional example is used by bringing a cool-to-the-touch fabric 2 with good thermal conductivity into contact with the contactee, which may be a human B or an animal A, and water is constantly supplied to the entire surface of this cool-to-the-touch fabric 2 from a highly absorbent material 3. Therefore, the entire surface of the cool-to-the-touch fabric 2 is constantly wet with water, and the wet state is transferred to the skin that comes into contact with the cool-to-the-touch fabric 2 directly or through underwear, etc., resulting in a sticky feel and a poor comfort.
[0006] Therefore, an object of the present invention is to improve comfort. [Means for solving the problem]
[0007] To achieve this objective, the cooling clothing of the present invention comprises a clothing body formed by a three-dimensional mesh structure, and a surface cloth placed on at least one of the outer surfaces of the front side or the back side of the clothing body, with at least a portion of the surface cloth in contact with the outer surface, and a liquid supply pipe having a plurality of liquid outlet holes on its outer circumferential surface is arranged on the surface cloth, and liquid is supplied to the liquid supply pipe from a liquid supply means. The three-dimensional mesh structure is formed by twisting a plurality of fibers together, and using twisted fibers in which capillary-forming gaps are formed between adjacent fibers. Furthermore, the fibers constituting the three-dimensional network structure are water-repellent fibers. The surface fabric is made of a water-absorbent fiber alone or a composite fiber of a water-absorbent fiber and a water-repellent fiber. Furthermore, the upper part of the surface cloth is a liquid supply pipe arrangement area, and the lower part of the surface cloth is a liquid supply pipe non-arrangement area, and a liquid supply pipe having a plurality of liquid outflow holes on its outer surface is arranged in the liquid supply pipe arrangement area, and liquid is supplied to this liquid supply pipe from a liquid supply means. The liquid supply pipe was made of hollow fibers. Furthermore, the liquid supply means is configured by an electric pump or a manual pump. Furthermore, the cooling clothing system of the present invention comprises the cooling clothing and an outer clothing body to be worn on the outside of the cooling clothing, and the outer clothing body is configured to have a ventilation means disposed therein for taking in air from outside the outer clothing body into the outer clothing body.
[0008] In addition, the cooling clothing system of the present invention comprises a cooling clothing and an outer clothing body to be worn on the outside of the cooling clothing, and a ventilation means is arranged in the part of the outer clothing body facing the area of the cooling clothing where the liquid supply pipe is not arranged, to draw air outside the outer clothing body into the outer clothing body. [Effects of the Invention]
[0009] As described above, the cooling clothing of the present invention comprises a clothing body formed from a three-dimensional mesh structure, and a surface cloth placed on at least one of the outer surfaces of the front side or the back side of the clothing body, with at least a portion of the surface cloth in contact with the outer surface, and a liquid supply pipe having a plurality of liquid outlet holes on its outer periphery is arranged on the surface cloth, and liquid is supplied to the liquid supply pipe from a liquid supply means, making the clothing extremely comfortable. In other words, in the present invention, it is the clothing body formed from a three-dimensional mesh structure that comes into contact with the skin directly or through, for example, underwear, and since this clothing body is formed from a three-dimensional mesh structure, it comes into point contact with the skin or underwear. Furthermore, the liquid is supplied to the clothing body from the outer fabric on the side opposite the skin, and the liquid is also supplied from the outer fabric to the clothing body from the point where the outer fabric and the clothing body come into contact. As a result, most of the liquid supplied from the surface fabric to the clothing body vaporizes as it travels through the three-dimensional mesh structure of the clothing body toward the skin, and the heat of vaporization at this time exerts a cooling effect on the skin, and since the liquid does not substantially reach the skin, there is no sticky feeling on the skin, making it highly comfortable. Furthermore, the cooling clothing system of the present invention is configured such that an outer garment is worn on the outside of the cooling clothing, and the outer garment is provided with an air-blowing means for drawing air from outside the outer garment into the outer garment; the air blown by the air-blowing means promotes the evaporation of liquid that flows toward the skin through the three-dimensional mesh structure of the cooling clothing, enhancing the cooling effect on the skin due to the heat of evaporation; and the lack of stickiness on the skin is further felt, resulting in a high level of comfort.

[0011] (Embodiment 1) 1 to 8 show a cooling system using cooling clothing according to one embodiment of the present invention. As shown in Fig. 1, the cooling system of this embodiment comprises a cooling garment 1 and an outer garment 2 that is worn on the outside of the cooling garment 1. As shown in Fig. 2, a ventilation means 3 is provided on the lower back side of the outer garment 2 to draw air outside the outer garment 2 into the outer garment 2. The ventilation means 3 is a battery-operated fan or the like.
[0012] The specific configuration of the cooling clothing 1 is shown in FIGS. First, this cooling clothing 1 comprises a vest-shaped clothing body 4 formed by a three-dimensional mesh structure as shown in Figures 7 and 8, and a vest-shaped outer cloth 5 arranged with at least a part of it in contact with the outer surface of the clothing body 4 as shown in Figure 6. That is, the vest-shaped outer cloth 5 shown in FIG. 6 is laid on the outer surface of the vest-shaped clothing main body 4 formed by the three-dimensional mesh structure shown in FIGS. 7 and 8, and the outer peripheries of the vest-shaped clothing main body 4 and the vest-shaped outer cloth 5 are sewn together as shown in FIG. 5, thereby forming the vest-shaped cooling clothing 1 as a whole shown in FIGS. 3, 4, and 5. As shown in Figs. 3, 4 and 5, a fastener 6 is provided on the front side of the vest-shaped cooling clothing 1, making it easy to put on and take off the vest-shaped cooling clothing 1.
[0013] Next, the vest-shaped clothing body 4 will be described. As can be seen from FIGS. 7 and 8, the clothing body 4 has a three-dimensional mesh structure. More specifically, for example, a three-dimensional mesh structure is formed using twisted fibers in which a plurality of polyester fibers, which are an example of water-repellent fibers, are twisted together. The reason why a three-dimensional network structure is formed using twisted fibers in which a plurality of fibers are twisted together is to form capillary-forming gaps between adjacent fibers in the twisted fibers.
[0014] Next, the surface fabric 5 will be described. As described above, the outer fabric 5 is also in the shape of a vest, and on the inner surface of the back side and the inner surface of the front side, as shown in Figure 6, liquid supply pipes 7 with multiple liquid outlet holes (not shown) on their outer surfaces are arranged. Specifically, this liquid supply pipe 7 is made of, for example, hollow fiber membranes, and one end opening and the other end opening of multiple hollow fiber membranes are connected to the water outlet portion of nipple 8, and the middle portion is arranged in a serpentine shape from above to the middle of surface fabric 5. The hollow fiber membrane has, for example, an outer diameter of about 0.5 mm, and has numerous liquid outlet holes of about 0.4 μm or less formed on the outer circumferential surface. Furthermore, water (an example of a liquid) in a container 11 is supplied to the water inlet of the nipple 8 via a pipe 9 and a pump 10 provided as an example of a liquid supply means. As shown in FIG. 3, a pocket 12 for storing a pump 10 and a container 11 is provided on the front side of the surface cloth 5. There are two pockets 12, and the pocket 12 on the left side of Figure 3 is for storing the pump 10 and container 11. This pocket 12 is provided with a transparent window 13 so that the pump 10 can be easily started or the amount of water in the container 11 can be easily checked.
[0015] As shown in FIG. 6, the liquid supply pipe 7 is provided up to 60% of the top of the surface cloth 5 . That is, the upper part of the surface cloth 5, which is up to 60% from the top, is the liquid supply pipe arrangement area 14, and the lower part, which is more than 60% from the top, is the liquid supply pipe non-arrangement area 15. The above-mentioned liquid supply pipe 7 is arranged in the liquid supply pipe arrangement area 14, and water (an example of a liquid) in the container 11 is supplied to this liquid supply pipe 7 via a pump 10 provided as an example of a liquid supply means. The surface cloth 5 is made of a water-absorbent fiber alone or a composite fiber of a water-absorbent fiber and a water-repellent fiber. What is important is that the water supplied via the liquid supply tube 7 penetrates and spreads over the surface fabric 5 .
[0016] Next, the outer garment 2 will be described. This outer garment 2 has already been put to practical use and is commercially available, and as described above, on the back side thereof is provided air blowing means 3 for drawing air outside the outer garment 2 into the outer garment 2.
[0017] What is important in this embodiment is that the portion of the surface fabric 5 corresponding to the position of the air blowing means 3 is the liquid supply pipe non-placement area 15 described above. This outer garment 2 is designed to have little air leakage, so when the air blowing means 3 is driven, air outside the outer garment 2 is taken into the outer garment 2 as shown in Figure 2, and some of it travels upward between the outer garment 2 and the surface cloth 5, and eventually is exhausted to the outside of the outer garment 2 through the collar 16 of the outer garment 2. At this time, part of the water in the surface cloth 5 evaporates, and the heat of evaporation can lower the temperature inside the outer garment 2.
[0018] In addition, in the liquid supply pipe non-positioned area 15 of the surface cloth 5 facing the air blowing means 3, air outside the outer garment body 2 is taken into the outer garment body 2, and some of this air then passes through the surface cloth 5 and travels upward inside and outside the vest-shaped clothing body 4 formed by the three-dimensional mesh structure, and eventually is exhausted to the outside of the outer garment body 2 from the collar 16 of the outer garment body 2.
[0019] A feature of this embodiment is that the cooling clothing 1 comprises a vest-shaped clothing body 4 formed by a three-dimensional mesh structure as shown in Figures 7 and 8, and a vest-shaped outer cloth 5 arranged so that at least a portion of it is in contact with the outer surface of the clothing body 4 as shown in Figure 6. That is, the vest-shaped outer cloth 5 shown in FIG. 6 is laid on the outer surface of the vest-shaped clothing main body 4 formed by the three-dimensional mesh structure shown in FIGS. 7 and 8, and the outer peripheries of the vest-shaped clothing main body 4 and the vest-shaped outer cloth 5 are sewn together as shown in FIG. 5, thereby forming the vest-shaped cooling clothing 1 as a whole shown in FIGS. 3, 4, and 5.
[0020] In the above-described configuration, the user first puts on the cooling clothing 1 shown in FIG. 3, then puts on the outer clothing 2 over it, and drives the pump 10 and the air blowing means 3. The water in the container 11 is then supplied via the pump 10, piping 9, and nipple 8 to the liquid supply pipe 7 arranged in the liquid supply pipe arrangement area 14 of the surface fabric 5, and flows out from the multiple liquid outflow holes of the liquid supply pipe 7 onto the surface fabric 5, wetting a wide area of the surface fabric 5. A clothing body 4 formed of a three-dimensional mesh structure is provided inside this surface cloth 5, so that some or all of the water in the surface cloth 5 is supplied to the clothing body 4, which is made of a three-dimensional mesh structure that is in point contact with this surface cloth 5.
[0021] The clothing body 4 is made of a three-dimensional mesh structure using, for example, twisted fibers made by twisting together multiple polyester fibers, which is an example of a water-repellent fiber, in order to maintain the strength to maintain the shape of the three-dimensional mesh structure. In addition, the reason for using twisted fibers made by twisting multiple polyester fibers together to form a three-dimensional mesh structure is that capillary-forming gaps are formed between adjacent fibers in the twisted fibers, and water is transported to the skin A side through these capillary-forming gaps.
[0022] In this embodiment, the clothing body 4 formed from a three-dimensional mesh structure comes into contact with the skin A directly or through, for example, underwear, and since the clothing body 4 is formed from a three-dimensional mesh structure, it comes into point contact with the skin A or underwear, etc. In addition, liquid is supplied to the clothing body 4 from the surface cloth 5 on the opposite side to the skin A, and the liquid is also supplied from the surface cloth 5 to the clothing body 4 from the point where the surface cloth 5 and the clothing body 4 come into contact.
[0023] As a result, most of the liquid supplied from the surface cloth 5 to the clothing body 4 vaporizes as it travels through the three-dimensional mesh structure of the clothing body 4 toward the skin A, and the heat of vaporization at this time exerts a cooling effect on the skin A area. Moreover, since the liquid does not substantially reach the skin A area due to the evaporation effect, the sticky feeling on the skin A area is eliminated, resulting in a high level of comfort. Furthermore, the cool air generated by the heat of vaporization in the three-dimensional mesh structure of the clothing body 4 is effectively utilized to cool the skin A near the skin because the surface cloth 5 is present on the outside.
[0024] In addition, in this embodiment, an outer garment 2 is worn on the outside of the cooling clothing 1, and the outer garment 2 is provided with an air blowing means 3 that draws air outside the outer garment 2 into the outer garment 2. Therefore, the air blown by the air blowing means 3 promotes the evaporation of the liquid that flows through the three-dimensional mesh structure of the cooling clothing 1 toward the skin A, enhancing the cooling effect on the skin A due to the heat of evaporation, and furthermore, the lack of stickiness on the skin A can be more strongly felt, resulting in high comfort.
[0025] The reason why the portion of the surface cloth 5 corresponding to the position of the air blowing means 3 of the outer garment 2 is made the above-mentioned liquid supply pipe non-placement area 15 is that when the portion of the surface cloth 5 is wet with water, it becomes difficult for the air from the air blowing means 3 to pass through this portion of the surface cloth 5, so in order to avoid this, the portion of the surface cloth 5 corresponding to the position of the air blowing means 3 of the outer garment 2 is made the liquid supply pipe non-placement area 15. As a result, as shown in Figure 2, part of the air blown by the air blowing means 3 passes through the outer fabric 5 of the cooling garment 1 and travels upward inside and outside the garment body 4, which is made of a three-dimensional mesh structure, promoting the evaporation of the liquid that travels from the outer fabric 5 through the garment body 4 toward the skin A, thereby enhancing the cooling effect on the skin A due to the heat of evaporation. This air blowing also makes the skin A feel even less sticky, resulting in greater comfort.
[0026] In the above embodiment, the electric pump 10 is used as the liquid supply means, but the liquid supply means may be configured by a manual pump. The garment body 4 of this embodiment is formed from a three-dimensional mesh material as described above. The three-dimensional mesh material described here has the following structure: For example, a mesh-like front body (twisted fibers) and a mesh-like back body (twisted fibers) are separated by a plurality of columns (twisted fibers) that create gaps between the front body and the back body. The front body and the back body each have openings that are, for example, circular, elliptical, triangular, rectangular, pentagonal, hexagonal, or octagonal. In addition, gaps are formed between the multiple pillars that create gaps between the front and back bodies. For example, when a rectangular opening is formed in the front and back bodies, the pillars that create gaps between the front and back bodies are formed at each corner of the rectangle. Therefore, in the clothing body 4, there is an air flow that flows from one side of the front and back bodies to between the front and back bodies, and between the front and back bodies. In this embodiment, this configuration is described as a three-dimensional mesh material.
[0027] (Embodiment 2) 9 to 16 show a cooling system using cooling clothing according to another embodiment of the present invention. In the embodiment of Figures 9 to 16, in order to avoid complicating the explanation, the same parts as those in the embodiment shown in Figures 1 to 8 are given the same symbols, and only the characteristic parts will be explained, but the parts with the same symbols have the same configuration as the above embodiment.
[0028] In this embodiment, as shown in Figures 11 to 13, a collar 17 is provided on the surface cloth 5, and a liquid supply pipe 7 made of a hollow fiber membrane is also provided on the inner surface of this collar 17, and is connected to a pipe 9 via a nipple 8. That is, a liquid supply pipe 7 made of a hollow fiber membrane is provided in the collar 17 portion, and the collar 17 portion is wetted with water, and the water in the collar 17 portion is evaporated by the wind that flows upward inside and outside the clothing body 4 made of a three-dimensional mesh structure.
[0029] In another embodiment of the present invention, the surface cloth is arranged so as to be in contact only with the outer surface of the front side of the clothing body. In another embodiment, the surface cloth is arranged so as to be in contact only with the outer surface of the back side of the clothing body. In another embodiment, the three-dimensional mesh structure is made of a material other than water-repellent fibers.
[0030] Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above-described embodiments, and various design modifications can be made to the present invention without departing from the scope of the claims.
