As the fabric forming the left and right front surface portions 401R and 401L and the rear surface portion 402, a fabric having breathability is used. As the breathable fabric, for example, a mesh fabric made of synthetic fibers can be used. Examples of the synthetic fiber forming the mesh fabric include polyester, nylon, polyurethane and the like. In the drawings, the mesh patterns of the left and right front portions 401R and 401L and the rear surface portions 402 are not shown.

A cushioning material 408 having elasticity and breathability is interposed between the outer material 406 and the lining 407 of the rear surface portion 402. That is, the bodice 400 is provided with a cushioning material 408 having breathability and elasticity on the back, shoulders and flanks of the body. The cushion material 408 can be used even when a load is applied to the clothes, for example, when the user wears a harness or suspenders on the outer garment 300 or carries heavy luggage or equipment on the outer garment 300. By receiving the load and preventing the space between the inner garment 100 and the body from being crushed, an air flow path for ensuring the flow of air sent from the blower 1 in the inner garment 100 is formed. , It is intended to prevent the obstruction of the ventilation in the inner garment 100.

As the cushion material 408, if it has elasticity and breathability, and can secure an air flow path in the inner garment 100 against a load applied from above the outer garment 300 and prevent obstruction of ventilation. Although not particularly limited, for example, a three-dimensional network structure of a thermoplastic resin, a double Russell knit using synthetic fiber filaments such as ester, nylon, polypropylene, and polyethylene can be used. Among them, considering the cushioning property that can effectively prevent the air blown inhibition in the inner garment 100 when a load is applied, the wearing feeling when wearing the bodice 400, and the workability of the cushioning material 408, 3 A dimensional network structure can be preferably used. The three-dimensional network structure is formed by forming a random loop of a large number of lines made of a thermoplastic elastic resin and fusing at least a part of the contact points of the lines. Examples of the thermoplastic elastic resin forming the three-dimensional network structure include polyester-based, polyolefin-based, and polyurethane-based thermoplastic resin elastomers.

When the apparent density of the cushion material 408 is 10 kg / m ³ or more, an air flow path can be sufficiently formed in the inner garment 100 when a load is applied, and the airflow obstruction in the inner garment 100 is satisfactorily prevented. On the other hand, when the apparent density of the cushion material 408 is 100 kg / m ³ or less, the wearing feeling of the bodice 400 is not impaired, and the comfort of the bodice 400 can be improved. Because.

Further, the cushion material 408 is not particularly limited, but the recovery rate after compression by 50% in the thickness direction thereof is preferably 70% or more, and more preferably 80% or more. When the recovery rate after compressing the cushion material 408 by 50% in the thickness direction is 70% or more, an air flow path can be sufficiently formed in the inner garment 100 when a load is applied, and the inside of the inner garment 100 can be sufficiently formed. In addition to being able to satisfactorily prevent airflow inhibition in, it can satisfactorily withstand repeated use.

Next, as shown in FIGS. 5 and 14 to 18, the blower 1 includes a tubular container 2, a blower means 3 for circulating air in the tubular container 2, and at least a part of the tubular container 2. It is configured to include at least a moisture absorbing material 4 housed in the container 2 and a heat storage material 5 housed in at least a part of the tubular container 2.

The tubular container 2 has an air inlet 6 at one end (left end in the illustrated example) and an air outlet 7 at the other end (the right end on the opposite side in the illustrated example) facing the one end. The air outlet 7 is directly or indirectly connected to the tip portion 201 of the blow jig 200 via the blow hose 500. The air inlet 6 takes in air into the tubular container 2 from the outside, the air outlet 7 sends out the air in the tubular container 2 to the outside, and the inside of the tubular container 2 is air from the air inlet 6 toward the air outlet 7. It is a flow passage through which air flows. The tubular container 2 can be made of, for example, metal or resin, but is preferably made of aluminum from the viewpoint of heat dissipation and light weight.

The tubular container 2 is composed of a plurality of parts, and includes a casing 8 forming an outer shell, a lid 9 that can be attached to and detached from the casing 8, a container 10 that can be housed in the casing 8, and a container 10 and a lid 9. A spacer 11 is provided between the two.

As shown in FIGS. 5 and 14, the casing 8 has an opening at one end (left end in the illustrated example) and penetrates through the end wall 80 on the other end (right end on the opposite side in the illustrated example) facing the one end. A tubular air outlet 7 is integrally provided so as to communicate with the hole. A male screw 82 is provided on the outer peripheral surface of the casing 8 on one end side of the peripheral wall 81, and the lid 9 is attached to the casing 8 by screwing it with the female screw 92 provided on the lid 9. The peripheral wall 81 of the casing 8 is formed in a size capable of accommodating the container 10 and the spacer 11 inside.

As shown in FIGS. 5 and 15, the lid 9 has an opening at one end (the right end in the illustrated example) and penetrates the center of the lid 9 through the end wall 90 on the other end (the left end on the opposite side in the illustrated example) facing the one end. A tubular air inlet 6 is integrally provided so as to communicate with the hole. A female screw 92 is provided on the inner peripheral surface of the peripheral wall 91 of the lid 9. A plurality of screw holes 93 are formed at intervals in the end wall 90 of the lid 9. The plurality of screw holes 93 are for attaching a fan as a blowing means 3 to the lid 9 by using a bolt 12 or the like.

As shown in FIG. 5, the air blowing means 3 forcibly generates an air flow inside the tubular container 2 and allows air to flow in the tubular container 2 from the air inlet 6 to the air outlet 7. As the blowing means 3, for example, a fan can be used. The fan is attached to the lid 9 so that the axis of rotation coincides with the central axis of the tubular container 2. Although not shown, electric power for driving is supplied to the fan from a power source such as a battery or a power supply device. The fan may be driven and stopped, and the rotation speed may be controlled by connecting a switch for switching on / off and blowing strength.

As shown in FIGS. 5 and 16, the container 10 accommodates the moisture absorbing material 4 and the heat storage material 5. In the present embodiment, the container 10 accommodates the moisture absorbing material 4 and the heat storage material 5 in a mixed state. The accommodator 10 has openings for air in and out at both ends, and is installed in an air flow passage in the casing 8. When the air passes through the container 10, it comes into contact with the hygroscopic material 4, so that the water vapor contained in the air is adsorbed by the hygroscopic material 4 and the air is dehumidified. At this time, since the adsorption of water vapor by the moisture absorbing material 4 is an exothermic reaction, heat of adsorption is generated in the moisture absorbing material 4 with the adsorption of water vapor, but this heat of adsorption is transferred to the heat storage material 5 and stored as latent heat. Therefore, the heat of adsorption suppresses the temperature rise of the air that has passed through the moisture absorbing material 4. Therefore, even if the air taken in from the air inlet 6 contains a large amount of water vapor, it can be sent out to the air outlet 7 as dry low-temperature air.

In the present embodiment, in the container 10, the opening on the air inlet 6 side is closed by a porous plate 13 in which a plurality of holes are uniformly formed at intervals, and the opening on the air outlet 7 side is closed. However, it is closed with a mesh-like mesh material 14 having a plurality of meshes. The plate material 13 and the net material 14 are made of a metal such as aluminum, and prevent the moisture absorbing material 4 and the heat storage material 5 in the container 10 from leaking to the outside of the container 10. Further, since the opening on the air inlet 6 side of the container 10 is closed by the porous plate material 13, the air introduced from the air inlet 6 spreads in the radial direction along the surface of the plate material 13. Since it is taken into the container 10 from each hole, it is evenly distributed in the container 10 in the radial direction. Therefore, the circulating air comes into contact with the moisture absorbing material 4 in the container 10 evenly, so that the air is effectively dehumidified. Then, since the opening on the air outlet 7 side of the container 10 is closed with the mesh-like mesh material 14, the dehumidified air is smoothly taken out from the inside of the container 10 from the plurality of meshes of the mesh material 14. Is sent to the air outlet 7.

Further, as shown in FIGS. 5 and 16 to 18, the container 10 has, in the present embodiment, a main body 110 that houses the moisture absorbing material 4 and the heat storage material 5, and a lid 114 that can be attached to and detached from the main body 110. It is composed of and. The main body 110 has a tubular shape with one end (left end in the illustrated example) open, and the net material 14 is integrally formed with the end wall 112 on the other end (right end on the opposite side in the illustrated example) facing the one end. It is provided. A female screw 113 is provided on the inner peripheral surface of the peripheral wall 111 of the main body 110 on one end side, and the lid 114 is attached to the main body 110 by screwing with the male screw 117 provided on the lid 114. Be done.

The lid 114 has a tubular shape with both ends open, and a plate member 13 is integrally provided in the opening. A flange 116 having a male screw 117 on the outer peripheral surface is integrally provided at one end (right end in the illustrated example) of the peripheral wall 115 of the lid portion 114.

As shown in FIGS. 5 and 16, the spacer 11 has a tubular shape with both ends open, and is interposed between the container 10 and the lid 9 in the casing 8. The spacer 11 secures a storage space for accommodating the blower means 3 between the container 10 and the lid 9 in the casing 8.

The hygroscopic material 4 adsorbs the water vapor contained in the air to bring the air sent to the air outlet 7 into a dry state. As the moisture absorbing material 4, a commonly used one can be used, but in order to improve the adsorption ability, it is preferable to use a large number of granular materials having pores. Examples of the hygroscopic material 4 include silica gel, zeolite, activated alumina, calcium chloride and the like. When the hygroscopic material 4 cannot adsorb water vapor, it is necessary to replace the hygroscopic material 4, but when silica gel, zeolite or the like is used as the hygroscopic material 4, the hygroscopic material 4 is heated to increase the adsorptive capacity. Can be regenerated.

The heat storage material 5 stores the heat of adsorption generated when the air is dehumidified by the moisture absorbing material 4, thereby suppressing the temperature rise of the air due to the heat of adsorption and keeping the air sent to the air outlet 7 in a low temperature state. As the heat storage material 5, for example, a large number of heat storage capsules in which a phase changing substance that absorbs latent heat depending on the temperature is encapsulated in a capsule or the like can be used. As the heat storage capsule, those described in Japanese Patent No. 45088867 and Japanese Patent No. 4861136 can be used. By uniformly mixing the heat storage material 5 with the moisture absorbing material 4 in the container 10, the heat storage material 5 comes into good contact with the moisture absorbing material 4, and the efficiency of transferring the heat of adsorption to the heat storage material 5 becomes high. Therefore, it is possible to effectively suppress the temperature rise due to the heat of adsorption of the air that has passed through the moisture absorbing material 4. The heat storage material 5 is not limited to the heat storage capsule described above, and various materials can be used as long as they can store heat of adsorption.

Next, a method of using the cooling clothes 1000 of the present embodiment described above will be described. As shown in FIG. 7, the user first wears the bodice 400 on the body (or on the underwear), then wears the inner garment 100 on it as shown in FIG. 2, and in FIG. As shown, the outer garment 300 is further worn on it. When wearing the inner garment 100 and the outer garment 300, the first through hole 105 and the blower jig 200 are directed from the inside of the inner garment 100 to the outside of the outer garment 300 so that the tip portion 201 of the blower jig 200 protrudes to the outside of the outer garment 300. Through the second through hole 302, as shown in FIG. 1, the air outlet 7 of the blower device 1 is directly or indirectly connected to the tip portion 201 of the blower jig 200 via the blower hose 500. The blower device 1 can be attached around the waist of the user by providing, for example, an attachment means (not shown) for attaching to the outer garment 300 of the user or a belt wrapped around the trousers.

In this state, when the blowing means 3 of the blowing device 1 is driven, the outside air (air) is taken into the tubular container 2 through the air inlet 6 and sent out from the air outlet 7 into the inner garment 100 worn by the user. Is done. The air sent into the inner garment 100 passes through the inner garment 100 along the user's body, so that the sweat of the body is easily vaporized, and the cooling effect when the sweat is vaporized increases the body temperature of the user. It can promote a decline. Further, even if hot and humid air is taken into the tubular container 2 from the air inlet 6, the water vapor contained in the air is adsorbed by the moisture absorbing material 4 and the dry air is sent out into the inner garment 100 and also absorbs moisture. The heat of adsorption generated when the air is dehumidified by the material 4 is stored in the heat storage material 5, and the temperature rise of the air sent out into the inner garment 100 is suppressed. Therefore, the space inside the inner garment 100 can be made into a comfortable environment.

In the present embodiment, the outside air is simply introduced into the blower 1, but the outside air may be introduced by using a compressed air source such as a compressor or an air cylinder (high pressure air cylinder). Alternatively, outside air may be introduced into the blower 1 by using an electric blower (clean air supply unit or the like) installed in a place with fresh air.

As described above, according to the cooling clothes 1000 of the present embodiment, the inner garment 100 worn by the user under the outer garment 300 is non-breathable, and the inside of the inner garment 100 is highly airtight, so that air is blown. It is possible to prevent the air sent to the inside of the inner garment 100 by the device 1 from leaking to the outside of the inner garment 100. Therefore, the air sent to the inside of the inner garment 100 by the blower 1 flows stably along the body of the user inside the inner garment 100, so that the air spreads widely inside the inner garment 100. Body sweat evaporates well. As a result, the cooling effect of the body using the heat of vaporization can be effectively obtained.

Therefore, the cooling clothes 1000 of the present embodiment are necessary for protection from the outside, but are suitable when the clothes that are accompanied by heat and stuffiness due to wearing are the outer clothes 300.

By wearing under 100, the space between the inner garment 100 and the body is not crushed by the cushion material 408 at the part that hits the back of the body, so that the air flow is not obstructed in the inner garment 100 and the air is not obstructed. The flow path is sufficiently secured. Therefore, the air sent from the blower 1 into the inner garment 100 spreads over a wide area through the back to the front side (chest and ventral side) of the body, so that the sweat of the body is satisfactorily vaporized and the heat of vaporization is used. The cooling effect of the body can be effectively obtained. In particular, in the present embodiment, since the bodice 400 also includes the cushioning material 408 on the shoulders and flanks of the body, the air sent from the blower 1 into the inner garment 100 is passed from the back to the shoulders and flanks of the body. Since it can be satisfactorily distributed to the anterior side (chest and ventral side), the cooling effect of the body can be obtained more effectively.

Further, according to the cooling clothes 1000 of the present embodiment, since the heat storage material 5 is housed in the tubular container 2 together with the moisture absorbing material 4 in the blower device 1, the air to be sent into the inner garment 100 with a simple structure. Dehumidification can be realized, and the device can be made smaller and lighter. The size of the blower 1 is preferably a size that does not significantly affect the work, and the weight is preferably 3 kg or less, for example.

Further, according to the cooling clothes 1000 of the present embodiment, the tubular container 2 of the blower 1 is composed of the casing 8, the lid 9, and the container 10, and the container 10 can be replaced. When the adsorption capacity and the heat storage capacity of the heat storage material 5 reach the limit, the moisture absorbing material 4 and the heat storage material 5 can be easily replaced.

In addition, since the container 10 is composed of the main body 100 and the lid 104, and the moisture absorbing material 4 and the heat storage material 5 can be easily taken out, when the adsorption capacity of the moisture absorbing material 4 reaches the limit, the moisture absorbing material 4 is absorbed. The material 4 can be easily taken out and regenerated by heating or the like.

Examples of the present invention will be shown below, and the present invention will be described in more detail, but the present invention is not limited to the following examples.

A test was conducted on the amount of air blown and the cooling performance of the body by blowing air, with and without the inner garment under the outer garment. Specifically, a sweating mannequin with sweat-absorbing underwear was prepared in a room controlled at 32 ° C. and 60% RH, and the inner garment and outer garment were put on the sweat-absorbing underwear in this order. A comparative example was wearing underwear. The skin temperature of the sweating mannequin was controlled to 35 ° C. For the outer garment, a non-breathable wing (commercially available) was used, and for the inner garment, a waterproof and breathable cloth in which a nylon woven fabric was coated with polyurethane resin was used. As the nylon woven fabric used, a ^{plain woven fabric having a mass of 60 g / m 2} composed of 78 decitex 96 filaments was smelted, dyed, water-repellent treated and dried by a conventional method, and then coated with a urethane resin solution using a coater. This was introduced into water at 20 ° C., solidified for 3 minutes, and then dried in an oven at 130 ° C. to obtain a microporous membrane having a resin layer thickness of 45 μm. The thickness of the obtained waterproof / moisture-permeable fabric was 0.22 mm, the mass was 95 g / m ² , and the moisture permeability was 115 g / m ² · h. The sweat-absorbing underwear was made of a sweat-absorbing material prepared by the following method. A polyester filament (84 decitex x 72 filament) was used, knitted with a smooth structure, refined by a conventional method, and further dyed with a disperse dye. Then, a hydrophilic agent (manufactured by Takamatsu Oil & Fat Co., Ltd., SR-1000) was padded and dried at a concentration of 1% to impart hydrophilicity. The knitted fabric thus obtained has a thickness of 0.80 mm, a mass of 153 g / m ² , a water absorption diffusivity (JIS L 1907 dropping method) of 2 sec or less, and a water absorption rate (JIS L 1907 Bilek method) of 100 mm. It was.

In both Examples and Comparative Examples, a sweating mannequin was ^{sweated at a sweating amount of 400 g / m 2} · hr for 15 minutes, and then the air in the room was blown for 60 minutes while sweating at the sweating amount. In the comparative example, a fan was used to blow air between the sweat-absorbing underwear and the outer garment. The air volume of the fan was 100 L / min, 200 L / min, and 400 L / min in both Examples and Comparative Examples. ^{The average heat dissipation amount (W / m 2} ) of the whole body of the sweating mannequin was calculated from the power consumption required to control the skin temperature of the sweating mannequin to 32 ° C. The result is shown in FIG.

According to FIG. 20, it was confirmed that wearing the inner garment under the outer garment doubles the amount of heat radiation and improves the cooling performance of the body as compared with the case where the inner garment is not worn. It was confirmed that the inside of the clothes can be made more comfortable by wearing.

INDUSTRIAL APPLICABILITY The present invention can be used when working at a work site, and is particularly suitable for use in a hot and humid environment in summer, and can greatly contribute to the industrial world.
