  When the blower of Patent Document 1 is used in a high-temperature and high-humidity environment, air containing a large amount of water vapor is sent into the clothes. However, if the air contains a large amount of water vapor, the clothes become hot and humid. It is an environment where sweat is unlikely to evaporate. Therefore, it is necessary to dehumidify the air sent into the clothes. For example, a humidifier such as silica gel or zeolite is housed in a blower, and when air passes through the blaster, it comes into contact with the humectant, thereby adsorbing water vapor contained in the air with the humectant to dehumidify the air. It has been proposed. However, the adsorption of water vapor by the moisture absorbent is an exothermic reaction, and the temperature of the moisture absorbent rises with the adsorption of the water vapor, so that the temperature of the air passing through the moisture absorbent becomes higher than the outside air. Therefore, in order to send air into clothes, it is necessary to cool the heated air.However, if a cooler such as a heat exchanger is provided in the blower, the size and weight of the device will increase. Issues.

  In addition, when wearing a harness or suspenders on clothes or carrying heavy luggage or equipment on clothes, the space between the clothes and the body is crushed and the air in the clothes is Since the flow is obstructed and the air from the air blower does not spread over a wide area of the body, there is also a problem that the vaporization of sweat cannot be expected and a sufficient cooling effect of the body using heat of vaporization cannot be obtained.

  The present invention has been made to solve the above problems, and an object of the present invention is to be able to dehumidify air sent from a blower into clothes with a simple configuration, and to secure the flow of air in clothes. To provide cooling equipment that can

  As a result of intensive studies, the present inventors have found that the above-described problems can be solved by the following means, and have reached the present invention. That is, the present invention has the following configuration.

1. A cooling device comprising a combination of a blower that cools a user's body by sending air into clothes and a cooling vest worn under the clothes, wherein the blower has an air inlet at one end. A cylindrical container having an air outlet at the other end opposite to the one end, air blowing means for flowing air into the cylindrical container from the air inlet to the air outlet, and at least one of the cylindrical container Part, and a heat storage material stored in at least a part of the cylindrical container, wherein the cylindrical container has openings at both ends and includes the hygroscopic material and the heat storage material.

9. Item 9. The cooling device according to any one of Items 1 to 8, wherein the moisture absorbing material and the heat storage material are housed in the cylindrical container in a state where they are separated from each other.

  According to the present invention, the blower is mounted on the waist of, for example, a user's pants, and the blower is driven, whereby air is taken into the cylindrical container from the air inlet, and the air is discharged from the air outlet into the user's clothes. Air is blown out, and the air passes through the clothes along the user's body, evaporating the body's sweat, and the cooling effect when the sweat evaporates may promote a decrease in the user's body temperature. it can. Also, even if high-temperature and high-humidity air is taken into the cylindrical container from the air inlet, the moisture-absorbing material adsorbs the water vapor contained in the air and sends out the dried air into the clothes. The heat of adsorption generated at this time is stored in the heat storage material, and a rise in the temperature of the air sent into the clothes is suppressed.

  The cooling device according to the present invention is worn and used by a worker who performs work at a work site, for example, and blows air into clothes such as work clothes and protective clothes of the worker (user). It suppresses a rise in body temperature. In particular, for workers who work in high-temperature and high-humidity environments, the dehumidified air is blown into the clothing while suppressing the temperature rise, and the dehumidified air is suppressed by suppressing the ventilation in the clothing. By distributing it over a wide area, the interior of the clothes is made a comfortable environment. Hereinafter, embodiments of a cooling device according to the present invention will be described in detail with reference to the drawings.

  As shown in FIG. 1, a cooling device 30 according to the present embodiment includes a blower 1 that blows air into a user's clothes C to cool a user's body, and a cooling device worn under the clothes C. It consists of a combination with a bodice 20. The blower 1 is attached to the waist of the user by attaching it to the waist of the user's pants or a belt wound around the pants using attachment means (not shown). Alternatively, it may be mounted on the user's waist or back using mounting means (not shown) such as a belt or a band.

  FIG. 2 shows an internal configuration of the blower 1. The blower 1 includes a cylindrical container 2, a blowing unit 3 for flowing air through the cylindrical container 2, a hygroscopic material 4 contained in at least a part of the cylindrical container 2, and at least one of the cylindrical container 2. And at least a heat storage material 5 housed in the section.

  The cylindrical container 2 has an air inlet 6 at one end (the 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) opposed to the one end. The air inlet 6 takes in air from the outside into the cylindrical container 2, the air outlet 7 sends out the air in the cylindrical container 2 to the outside, and the inside of the cylindrical container 2 moves the air from the air inlet 6 to the air outlet 7. Is a flow passage through which the air flows. The cylindrical 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 cylindrical container 2 is composed of a plurality of parts, a casing 8 forming an outer shell, a lid 9 detachable from the casing 8, a container 10 put in the casing 8, a container 10 and the lid 9. And a spacer 11 interposed therebetween.

  As shown in FIGS. 2 and 3, the casing 8 has an opening at one end (the left end in the illustrated example) and a central penetrating end wall 80 at the other end (the right end on the opposite side in the illustrated example) facing the one end. A cylindrical air outlet 7 is integrally provided so as to communicate with the hole. A male screw 82 is provided on the outer peripheral surface on one end side of the peripheral wall 81 of the casing 8, and the lid 9 is attached to the casing 8 by screwing with a female screw 92 provided on the lid 9. The peripheral wall 81 of the casing 8 is formed to have a size that can accommodate the container 10 and the spacer 11 therein.

  As shown in FIGS. 2 and 4, the lid 9 is open at one end (the right end in the illustrated example), and has a central penetrating end wall 90 at the other end (the left end on the opposite side in the illustrated example) facing the one end. A cylindrical 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 in the end wall 90 of the lid 9 at intervals. The plurality of screw holes 93 are for attaching a fan as the blowing means 3 to the lid 9 using bolts 12 or the like.

  As shown in FIG. 2, the blowing means 3 forcibly generates a flow of air inside the cylindrical container 2, and causes air to flow through the cylindrical 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 such that the rotation axis coincides with the central axis of the cylindrical container 2. Although not shown, the fan is supplied with driving power from a power source such as a battery or a power supply device. The driving of the fan, the stop and the number of rotations of the fan may be controlled by connecting a switch for switching on / off and the blowing intensity.

  The container 10 accommodates the moisture absorbent 4 and the heat storage material 5 as shown in FIGS. In the present embodiment, the container 10 contains the moisture absorbing material 4 and the heat storage material 5 in a mixed state. The container 10 has openings at both ends for taking in and out of air, and is installed in an air flow passage in the casing 8. When the air comes into contact with the hygroscopic material 4 when passing through the container 10, 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 hygroscopic material 4 is an exothermic reaction, heat of adsorption is generated in the hygroscopic material 4 along with the adsorption of water vapor, but this heat of adsorption is transmitted to the heat storage material 5 and stored as latent heat. Thus, the temperature rise of the air that has passed through the hygroscopic material 4 due to the heat of adsorption is suppressed. Therefore, even if the air taken in from the air inlet 6 contains a large amount of water vapor, it can be sent to the air outlet 7 as dry low-temperature air.

  In the present embodiment, the container 10 has an opening on the air inlet 6 side closed by a porous plate 13 in which a plurality of holes are uniformly formed at intervals, and an opening on the air outlet 7 side. However, it is closed by a mesh-like mesh member 14 having a plurality of meshes. The plate member 13 and the net member 14 are made of metal such as aluminum, for example, and prevent the hygroscopic material 4 and the heat storage material 5 in the container 10 from leaking out of the container 10. Further, since the opening on the side of the air inlet 6 of the container 10 is closed by the porous plate 13, the air introduced from the air inlet 6 spreads radially along the surface of the plate 13. Since it is taken into the container 10 from each hole, it flows evenly in the container 10 in the radial direction. Therefore, the flowing air uniformly contacts the hygroscopic material 4 in the container 10, so that the moisture is effectively dehumidified. Since the opening on the air outlet 7 side of the container 10 is closed by the mesh material 14, the dehumidified air is smoothly taken out of the container 10 from the plurality of meshes of the mesh material 14. And sent to the air outlet 7.

  As shown in FIGS. 2 and 5 to 7, in the present embodiment, the container 10 includes a main body 100 that stores the moisture absorbent 4 and the heat storage material 5, and a lid 104 that is detachable from the main body 100. It is composed of The main body 100 has a tubular shape with one end (the left end in the illustrated example) opened, and the net material 14 is integrally formed with the end wall 102 on the other end (the right end on the opposite side in the illustrated example) facing the one end. Is provided. A female screw 103 is provided on the inner peripheral surface on one end side of the peripheral wall 101 of the main body 100, and the lid 10 is attached to the main body 100 by screwing with a male screw 107 provided on the lid 104. Can be

  The lid 104 has a tubular shape with both ends opened, and the plate 13 is integrally provided in the opening. One end (right end in the illustrated example) of the peripheral wall 105 of the lid 104 is integrally provided with a flange 106 having an external thread 107 provided on the outer peripheral surface.

  As shown in FIGS. 2 and 5, the spacer 11 has a cylindrical shape with both ends opened, and is interposed between the container 10 and the lid 9 in the casing 8. By the spacer 11, an accommodation space for accommodating the air blowing means 3 is secured between the container 10 and the lid 9 in the casing 8.

  The moisture absorbing material 4 makes the air sent to the air outlet 7 dry by absorbing the water vapor contained in the air. As the hygroscopic material 4, generally used materials can be used. However, in order to improve the adsorptivity, it is preferable to use a 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 moisture absorbing material 4 cannot absorb the water vapor, the moisture absorbing material 4 needs to be replaced. However, when silica gel, zeolite, or the like is used as the moisture absorbing material 4, the absorption capacity is increased by heating the moisture absorbing material 4. Can be played.

  The heat storage material 5 stores the heat of adsorption generated when the air is dehumidified by the hygroscopic material 4, thereby suppressing an increase in the temperature of the air due to the heat of adsorption and keeping the air sent to the air outlet 7 at a low temperature. As the heat storage material 5, for example, a large number of heat storage capsules obtained by encapsulating a phase change material that absorbs latent heat in accordance with the temperature in a capsule or the like can be used. As the heat storage capsule, those described in Japanese Patent No. 4508867 and Japanese Patent No. 4861136 can be used. By uniformly mixing the heat storage material 5 with the moisture absorbent 4 in the container 10, the heat storage material 5 comes into good contact with the moisture absorbent 4, and the efficiency of transmitting the heat of adsorption to the heat storage material 5 is increased. Therefore, the temperature rise due to the heat of adsorption of the air that has passed through the hygroscopic material 4 can be effectively suppressed. Note that the heat storage material 5 is not limited to the above-described heat storage capsule, and various materials can be used as long as the material can store heat of adsorption.

  Next, the cooling jacket 20 is worn by the user under the clothes C, as shown in FIG. 8 to 13 show an external configuration and an internal configuration of the cooling jacket 20. FIG. The cooling jacket 20 of the present embodiment is a vest-type cooling vest including left and right front portions 21R and 21L for covering the front side (chest side) of the body and a rear surface portion 22 for covering the back side (back side) of the body. The clothes can be easily worn and undressed by opening and closing the left and right front portions 21R and 21L with the fasteners 23.

  The left and right front portions 21R and 21L are formed in a size and shape that can cover the chest and the front side of the abdomen of the body. In the present embodiment, the left and right front portions 21R and 21L are formed of one piece of cloth, but may be formed of two pieces of cloth of a surface material and a lining material. On the other hand, the rear surface portion 22 is formed in a size and shape capable of covering up to both shoulders from the back of the body and up to the left and right flank (side flanks) at the side. The rear surface portion 22 is formed of two cloths, a front material 26 and a lining 27. The connection between the left and right front surfaces 21R and 21L and the rear surface 22 is provided with piping termination 24. In addition, the piping start 24 is also applied to the left and right front portions 21R, 21L and the rear portion 22 where the neck and both arms protrude, and the lower edge of the rear portion 22. Further, stitches 25 for sewing the outer material 26 and the lining 27 are provided at a plurality of places on the rear surface portion 22.

  As the cloth forming the left and right front parts 21R, 21L and the rear part 22, a cloth having air permeability is used. As the air-permeable cloth, for example, a mesh cloth made of synthetic fibers can be used. Examples of the synthetic fibers forming the mesh fabric include polyester, nylon, and polyurethane. In the drawings, the mesh patterns of the left and right front portions 21R, 21L and the rear portion 22 are not shown.

  A cushion material 28 having elasticity and air permeability is interposed between the outer material 26 and the lining 27 of the rear surface portion 22. That is, the cooling bodice 20 is provided with the cushioning material 28 having air permeability and elasticity at portions corresponding to the back, shoulders, and flank of the body. This cushioning material 28 can be used even when a load is applied to the clothes, for example, when the user wears a harness or suspenders on the clothes, or carries heavy luggage or equipment on the clothes. By receiving the load and preventing the space between the clothes and the body from being crushed, an air flow path that secures the flow of the air sent from the blower 1 in the clothes is formed, and the air flow in the clothes is reduced. This is to prevent inhibition.

  The cushioning material 28 is not particularly limited as long as it has elasticity and air permeability, and can secure the air flow path in the clothes against the load applied from above the clothes and prevent the inhibition of the ventilation. Although not limited thereto, for example, a three-dimensional network structure of a thermoplastic resin, a double Russell knitted fabric using synthetic fiber filaments such as ester, nylon, polypropylene, and polyethylene can be used. Among them, the three-dimensional structure is considered in consideration of the cushioning property capable of effectively preventing the air blow in the clothes when the load is received, the wearing feeling when the cooling jacket 20 is worn, the workability of the cushion material 28, and the like. A reticulated structure can be preferably used. In the three-dimensional network structure, a large number of filaments made of a thermoplastic elastic resin form random loops, and at least a part of a contact point of the filaments is fused. Examples of the thermoplastic elastic resin forming the three-dimensional network structure include a thermoplastic resin elastomer such as a polyester resin, a polyolefin resin, and a polyurethane resin. As the three-dimensional network structure, for example, one described in Japanese Patent No. 4802369 can be preferably used.

  The thickness of the cushion material 28 is not particularly limited, but is preferably 5 mm or more and 70 mm or less, more preferably 10 mm or more and 50 mm or less. When the thickness of the cushion material 28 is 5 mm or more, the air flow path can be sufficiently formed in the clothes when a load is applied, and the airflow inhibition in the clothes can be favorably prevented. If the thickness of the material 28 is 70 mm or less, the wearing comfort of the cooling jacket 20 can be improved without impairing the wearing feeling when the cooling jacket 20 is worn.

Further, the cushion material 28 is not particularly limited, but preferably has an apparent density of 10 kg / m ³ or more and 100 kg / m ³ or less. When the apparent density of the cushion material 28 is 10 kg / m ³ or more, an air flow path can be sufficiently formed in the clothes when a load is applied, and air blowing in the clothes can be prevented well. On the other hand, if the apparent density of the cushioning material 28 is 100 kg / m ³ or less, the wearing comfort of the cooling bodice 20 can be improved without impairing the wearing feeling when the cooling bodice 20 is worn. is there.

  Further, the cushion material 28 is not particularly limited, but preferably has a recovery rate after compression of 50% in the thickness direction of 70% or more, and more preferably 80% or more. When the recovery rate after compressing the cushion material 28 by 50% in the thickness direction is 70% or more, the air flow path can be sufficiently formed in the clothes when a load is applied, and the air flow in the clothes is inhibited. In addition to good prevention, it can withstand repeated use.

  Next, a method of using the above-described cooling equipment 20 of the present embodiment will be described. As shown in FIG. 1, the user first wears the cooling jacket 20 under the clothes C, and then attaches the blowing device 1 to a waist or a belt of pants so that the blowing device 1 can be used by the user. Wear it around your waist. Then, the blowing hose 15 connected to the air outlet 7 of the blowing device 1 is arranged in the clothes C. It is preferable that the blower hose 15 be fixed in the clothes C by fixing means (not shown). Thus, the attachment of the cooling device 30 to the user's body is completed.

  In this state, when the blowing means 3 of the blowing device 1 is driven, air is taken into the cylindrical container 2 from outside air via the air inlet 6, and is sent out from the air outlet 7 into the clothes C of the user. . When the air sent into the clothes C passes through the clothes C along the user's body, the sweat of the body is easily vaporized, and the cooling effect when the sweat is vaporized reduces the body temperature of the user. Can be encouraged. Further, even if high-temperature and high-humidity air is taken into the cylindrical container 2 from the air inlet 6, the moisture contained in the air is adsorbed by the moisture absorbent 4 and the dried air is sent out into the clothes C. The heat of adsorption generated during the dehumidification of the air by the heat storage 4 is stored in the heat storage material 5 and the temperature rise of the air sent into the clothes C is suppressed. Therefore, the space in the clothes C can be made a comfortable environment.

  As described above, according to the cooling equipment 30 of the present embodiment, since the heat storage material 5 is housed in the cylindrical container 2 together with the moisture absorbent 4 in the blower 1, the inside of the garment C has a simple structure. Dehumidification of the air to be sent can be realized, and the size and weight of the device can be reduced. The blower 1 preferably has a size that does not significantly affect the work, and a weight of, for example, 3 kg or less is preferable.

  In addition, according to the blower 1 of the present embodiment, even when a harness or a suspender is mounted on the clothes C, or when heavy luggage or equipment is carried on the clothes C, the cooling jacket 20 can be used. By wearing under the clothes C, the space between the clothes C and the body is not crushed by the cushioning material 28 at the portion corresponding to the back of the body, so that the flow of the air inside the clothes C is The flow path is sufficiently secured. Therefore, the air sent into the clothes C from the air blower 1 spreads widely through the back to the front side (chest and abdomen) of the body, so that the sweat of the body is well vaporized, and the body using the heat of vaporization is used. Can be effectively obtained. In particular, in the present embodiment, the cooling jacket 20 is provided with the cushioning material 28 also at a position corresponding to the shoulder and the flank of the body, so that the air sent into the clothes C from the blower 1 is passed through the shoulder and the flank from the back. Since it can be satisfactorily distributed on the front side (chest or abdomen), the body can be more effectively cooled.

  Moreover, according to the air blower 1 of this embodiment, since the cylindrical container 2 is comprised by the casing 8, the lid 9, and the container 10, and the container 10 is replaceable, the adsorption capacity of the hygroscopic material 4 and heat storage When the heat storage capacity of the material 5 reaches the limit, the moisture absorbing material 4 and the heat storage material 5 can be easily replaced.

  Further, since the container 10 is composed of the main body 100 and the lid 104 and the moisture absorbent 4 and the heat storage material 5 can be easily taken out, when the adsorbability of the moisture absorbent 4 reaches the limit, the moisture absorbent 4 4 can be easily taken out and heated to perform regeneration.

  As mentioned above, although one embodiment of the present invention was described, since the above-mentioned embodiment is an illustration in every point and is not restrictive, the present invention is not limited to the above-mentioned embodiment.

The sweat-absorbing material is preferably a material that absorbs and diffuses sweat and easily dissipates, and can be appropriately selected from synthetic fibers, such as polyester, nylon, polypropylene, and polyethylene, which are inherently hydrophobic. It is also an effective means to use those having improved water absorption / diffusion, water absorption speed and radiation by quality and surface treatment, and further use of ultra-fine fibers, fibers with irregular cross-sections and the like. It is also an effective means to use a fiber aggregate formed from a mixture of these fibers, a composite, and a mixed fiber. The sweat absorbing material is preferably in the form of a woven fabric, a knitted fabric, a nonwoven fabric, or the like. The method of fixing the cushion material 28 and the water-absorbing material is not particularly limited, and for example, sewing, bonding, or the like can be used. The water-absorbing material absorbs the sweat from the body, so that the sweat can be efficiently vaporized in the clothes by blowing from the blower 1, so that the heat of vaporization is effectively taken away, thereby cooling the body well. can do.

  Note that underwear or the like made using the above-mentioned sweat-absorbing material may be worn on the body, and the cooling jacket 20 may be worn from above.

  In the above embodiment, the outer jacket 26 is made of air-permeable fabric (specifically, mesh fabric). However, in order to increase the efficiency of air blowing in the clothes C, the outer jacket 26 is not woven. A gas-permeable (air-impermeable) material may be used. Examples of the non-breathable (air-impermeable) material include a material obtained by laminating or coating a resin on a fabric (woven fabric, knitted fabric, and nonwoven fabric), a material obtained by laminating a resin film on a fabric, and a resin film. .

  Further, in the above-described embodiment, the cooling jacket 20 does not include the cushioning material 28 on the left and right front portions 21R and 21L, which are the portions that contact the chest and abdomen of the body, but the cushioning material is also provided on the left and right front portions 21R and 21L. 28 may be provided.

  In addition, in the above-described embodiment, the cooling jacket 20 includes the cushioning material 28 at the portion corresponding to the shoulder and the flank, in addition to the portion corresponding to the back of the body, but the cushioning material 28 is not necessarily provided at the portion corresponding to the shoulder and the flank. It is not necessary.

  In the embodiment described above, the left and right front portions 21R and 21L of the cooling jacket 20 can be opened and closed by the fasteners 23. However, the left and right front portions 21R and 21L can be opened and closed by other means such as buttons and bands. It may be configured to be openable and closable, or may be configured to be connected in series without opening and closing the left and right front portions 21R and 21L.

Air (registered trademark) was enclosed. Breathair (TM) has a thickness of 15 mm, was used for apparent density 50 kg / ^{m 3.}

When wearing the cooling bodice, an undergarment made of a sweat-absorbing material was worn under the cooling bodice (on the skin). The sweat absorbing material was produced by the following method. Polyester filament (84 dtex x 72 filament) was used, knitted in a smooth structure, refined by a conventional method, and dyed with a disperse dye. Thereafter, a hydrophilizing agent (SR-1000, manufactured by Takamatsu Yushi Co., Ltd.) was padded and dried at a concentration of 1% to impart hydrophilicity. The knitted fabric thus obtained had a thickness of 0.80 mm, a mass of 153 g / m ² , a water absorption / diffusibility (JIS L 1907 dropping method) of 2 sec or less, and a water absorption rate (JIS L 1907 birec method) of 100 mm. Was. The sensory test was conducted by wearing a non-moisture wing (commercially available) on the cooling jacket and carrying a business backpack containing a 3 kg weight from the top of the wing under the blowing conditions described above. A monitor test was performed by three persons while air was blown from the air outlet through the hose through the inside of the wing and from the center of the lower end of the cooling jacket in parallel with the body. In the monitor test, after running on the treadmill (0 degree gradient) for 30 minutes (5 km / hr) for 30 minutes (5 km / hr) in an artificial climate room with an ambient temperature and humidity of 35 ° C. × 50% RH, the ventilation and cooling properties were determined by subjective reporting. did.
