Abstract

PROBLEM TO BE SOLVED: To provide a cooling clothing whose structure is simple, electricity consumption is low and by which a wearer can live comfortably even in high- temperature environment such as outdoor in the midsummer. SOLUTION: The body of this cooling clothing is provided with two cooling sheets 20 respectively in the front and the back and four cooling sheets 20 in total. The cooling sheet 20 is composed of a lower sheet 21, an upper sheet 22, a fan 23, a sponge 24 made of polyvinyl alcohol, an upper cloth 25, or the like. Air sucked by the fan 23 flows through a ventilating passage between the sheets 21 and 22 and is exhausted from an outlet 22d. Water fed on the right side of the lower sheet 21 contacts closely with air flowing from the upper part to the lower part in the ventilating passage to vaporize incessantly while the water diffuses on the surface of the sheet 21. At this very moment, the water eliminates heat of vaporization from surroundings, and the lower sheet 21 is cooled by the vaporization of water. Heat effused from the body of a wearer contacting closely with the sheet 21 is almost absorbed in the whole of the sheet 21, and the body is effectively cooled.

[0015]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a state in which a cooling garment 1 according to an embodiment of the present invention is worn. As shown in FIG. 1, the cooling garment 1 includes a vest-type main body 10, a hanging part 11 hung on a belt of pants, and a connecting part 12 connecting the main body 10 and the hanging part 11. The main body 10 is worn with the front zipper 32 opened, the arms passed through the sleeves one by one, and the zipper 32 closed, as in a normal vest.

FIG. 2 is a view showing the main body 10.
(A) shows a state viewed from the front, and (B) shows a state viewed from the rear. As shown in FIG. 2, two cooling sheets 20 (20 a, 20 b, 2
0c, 20d) are provided. The portion of the main body 10 other than the cooling sheet 20 is made of a stretchable fabric, for example, a polyurethane material called spandex. The stretchable fabric and the four cooling sheets 20 are sewn and connected to form a vest-type cooling garment 1. In this case, the back side of the cooling sheet 20 can be brought into close contact with the body of the wearer by making the dimensions slightly smaller so that the stretchable fabric stretches slightly when worn.

FIGS. 3A and 3B show the detailed structure of one of the cooling sheets 20a, wherein FIG. 3A is a front view and FIG. Note that FIG.
In (B), the thickness is exaggerated more than the actual cooling sheet for easy understanding. Other cooling sheet 2
The structures of 0b, 20c, and 20d are the same as those of 20a.
The cooling sheet 20 includes a lower sheet 21, an upper sheet 22, a fan 23, a sponge 24 made of polyvinyl alcohol (PVA), an upper cloth 25, and the like. In FIG. 3A,
The upper cloth 25 provided on the upper sheet 22 is omitted.

The lower sheet 21 is formed by laminating two materials. One material of the laminate structure has a property of allowing water vapor to easily permeate, but not allowing water to permeate even under considerable pressure (referred to herein as a “semi-permeable material”). ). Gore-Tex (registered trademark) manufactured by Gore-Tex is known as such a semi-permeable material. The other material constituting the laminate structure of the lower sheet 21 is a material that quickly diffuses water by capillary action, for example, a cotton cloth. A material obtained by laminating Gore-Tex with a cotton cloth is supplied to the general market and can be easily obtained. In the present embodiment, the lower sheet 21 having such a structure is used such that the Gore-Tex is on the back side (the side in contact with the body) and the cloth is on the front side. When water is supplied to the front side of the lower sheet 21, the water is rapidly diffused to the whole by capillary action, and the entire front side becomes wet in a short time, but this water is blocked by Gore-Tex and moves to the back side. Does not penetrate, so that the wearer's body and clothes do not get wet with water.

On the other hand, moisture evaporating from the wearer's body by skin respiration passes through GORE-TEX and reaches the front side.
As will be described later, the surface of the lower sheet 21 is deprived of heat by the vaporization of moisture, and the temperature is lowered. Therefore, the steam that has passed through Gore-Tex and reached the front side condenses to water when it touches the low temperature, but as described above, this water does not return to the back side, so the lower sheet is made of moisture evaporated from the wearer's body. The inside of 21 does not get stuffy.

The upper sheet 22 has a coarse mesh portion (mesh portion) 22a, a suction port 22b into which the fan 23 takes in air, a large number of projecting spacers 22c protruding inward, and a ventilation passage to be described later. An outlet 22d through which the flowing air is discharged is provided. These parts can be collectively formed as the upper sheet 22 by injection molding of a thermoplastic elastomer. By using such a material, the entire upper sheet 22 can be made flexible with elasticity like rubber.

The spacers 22c are arranged almost everywhere except for the suction port 22b and the discharge port 22d, for example, at intervals of 1 cm. In the mesh-like portion 22a, the spacers 22c are provided at portions where the length and width of the mesh cross each other. I have. Upper sheet 22
Is about 5 mm in the mesh-like portion 22 a, but the portion above this is about 8 mm in consideration of the thickness of the fan 23. The portion where the thickness changes from 5 mm to 8 mm is formed diagonally so that the thickness changes gradually. This is in consideration of making the upper sheet 22 easily bendable in any direction and improving comfort when worn.

The upper sheet 22 overlaps the lower sheet 22 with the side on which the spacer 22c is provided facing the lower sheet 21 side. In this state, the peripheral portions of the lower sheet 21 and the upper sheet 22 are adhered to each other to fix them. At this time, lower sheet 2
A space of about 4 mm is formed between the upper sheet 22 and the upper sheet 22 by the spacer 22c, and this portion becomes a ventilation path through which air flows.

The upper part of the mesh portion 22a of the upper sheet 22 is covered with an upper cloth 25. This is to prevent the air flowing through the ventilation passage from flowing out of the mesh portion 22a. In a normal use mode, the upper cloth 25 is attached so as to cover the mesh portion 22a so that the air sucked by the fan 23 flows from the top to the bottom in the ventilation path.

It is also conceivable to wear the cooling garment 1 as a vest without operating the fan 23 or supplying water. Even in such a case, since the upper cloth 25 easily transmits the water vapor, the water vapor coming out to the front side through the Gore-Tex of the lower sheet 21 is quickly released to the outside. Therefore, even in such a case, there is almost no feeling of discomfort due to sweat. When water is not supplied in this manner, it is not always necessary to use a water-resistant material such as Gore-Tex as the lower sheet 21, and any material that allows vaporized sweat to pass from the back side to the front side may be used.

When the cooling garment 1 is not considered to be worn as a vest, the upper sheet 22 is not provided with the mesh portion 22a, and the elastomer is formed so as to have a plate shape as a whole.

A fan 23 is mounted on the upper sheet 22 at the suction port 22b. FIG. 4 is a perspective view showing the appearance of the fan 23. Although a normal axial fan may be used as the fan 23, it is preferable to use a sirocco fan that sends out the air sucked from the shaft toward the outside in the radial direction of the blade for use in the present embodiment. . At the bottom of the fan 23, a fixing magic tape 23a is attached. The fan 23 is detachably fixed to the cooling sheet 20 by the magic tape 23a. An electrode 23b for supplying power is provided on the side surface of the housing of the fan 23. The cooling sheet 20 is sewn with an electric cable as described later, and an electrode (not shown) is attached to a tip end thereof. When the fan 23 is attached to the cooling sheet 20, the electrode
Is elastically pressed against the electrode 23b provided on the side surface of the electrode 23b, so that the electrode 23b surely comes into contact with the electrode 23b.

The weight of the cooling sheet 20 having such a structure can be reduced to about 100 g, and the total weight of the four cooling sheets 20 to about 400 g. Further, when spandex is used as the stretchable fabric, the total weight of the cooling garment 1 can be suppressed to about 700 g. With such a weight, even when worn at a work site or the like, there is no problem in the work. Further, when the fan 23 is removed from the cooling sheet 20 and the connector of the power cable is disconnected, the rest is only a water supply pipe, a spill pipe, a power cable, an elastomer, an elastic fabric, and a Gore-Tex described later. Therefore, if a water-resistant power cable is used, the main body 10 can be washed as it is, and the usability is excellent.

As shown in FIG. 3, a water supply port 26 is provided at the upper end of the cooling sheet 20. This water inlet 26
Is connected to a water supply pipe described later, and water passing through the water supply pipe is supplied to the cooling sheet 20 through the water supply port 26. Immediately below the water supply port 26, a PVA sponge 24 having a property of absorbing and retaining water is filled. This PV
The A sponge 24 is intended to serve as a water supply buffer. That is, by providing the PVA sponge 24 at this position, an appropriate amount of water supplied from the water supply port 26 is supplied to the lower sheet 21.

At the lower end of the cooling sheet 20, a drain port 27 is provided.
Is provided. As will be described later, the cooling suit 1 of the present embodiment cools the lower sheet 21 by vaporizing water diffused to the front side of the lower sheet 21, but does not vaporize all supplied water, but to some extent. The water is recovered as "spill water" without vaporization. The drain port 27 is provided to collect this spill water.
Is connected to a "spill pipe" described later, and is returned to the tank via the spill pipe.

Next, the hanging part 11 will be described. FIG.
Is a perspective view showing the appearance of the hanging part 11. Hanging part 1
1 is a role as a tank 40 for storing water, a battery, a volume 45 with a switch, a light emitting diode (LED)
46, and also serves as an electric unit 41 in which components necessary for electric operation such as a pump and a control circuit are put together.
The battery serves as a power supply for driving the fan 23 and the pump. The switch-equipped volume 45 is for turning on / off the fan 23 and the pump, and changing the interval of the fan 23 that operates intermittently to control the temperature. The pump is for sending the water stored in the tank 40 to the main body 10 at regular time intervals. However, since the amount of water to be sent is small, for example, a small pump using a bimorph is used. It is enough.

The hanging portion 11 is provided with a belt loop (not shown), through which a belt for trousers used by a wearer is passed. The hanging part 11 is connected to the main body part 10 by a connection part 12.
The connecting portion 12 is provided with a single connector including a water supply pipe, a spill pipe, and a power cable. The connector is fitted into the connector 42 on the side of the hanging portion 11 so that the water supply pipe, Each of the water pipe and the power cable is connected to a predetermined path of the hanging part 11. On the side of the main body 10, the water supply pipe, the spill pipe, and the power cable are sewn into elastic fabric.

The water stored in the tank of the hanging part 11 is sent out to the water supply pipe of the connection part 12 by a small pump provided in the electric unit 41, and from there, the water supply pipe 28 (FIG. 1 and FIG. 2), and is supplied to each cooling sheet 20 from a water supply port 26. Part of the water supplied to each cooling sheet 20 is absorbed by a PVA sponge 24 serving as a water supply buffer, and the rest is caused by capillary action of the cotton cloth on the front side of the lower sheet 21 and the surface of the cloth by the action of gravity. Spread and spread throughout. The process is
Water evaporates upon contact with air flowing through the flow passage.

In the present embodiment, as described above, a circulation type in which a part of the water supplied to the lower sheet 21 is collected as surplus water, instead of being diffused, is used. In other words, the amount of water supplied to the lower sheet 21 is adjusted so that a sufficient amount of the supplied water can be recovered as surplus water.
This is for the following reason. When the tap water is completely vaporized, a residue mainly composed of calcium carbonate contained in the tap water precipitates in the vaporized portion. Lower sheet 21
When such a residue is deposited and accumulated on the cloth, water hardly evaporates, and the cooling effect is reduced. Therefore, by using a circulation type, the precipitation of the residue is prevented.

FIG. 6 is a diagram showing a route in which sewage is recovered. A spill pipe 29 is connected to a drain port 27 provided at the lower end of each cooling sheet 20. A check valve 31 is attached to the end of the spill pipe 29 (the right end in FIG. 6). The drain 27 and the spill pipe 29
Is filled with a PVA sponge 30.
PVA sponge 30 is impermeable to air when absorbing water. However, the water in the PVA sponge 30 flows downward gradually by the action of gravity and drops. Pump 47
When water is sucked up from the tank 40, the pressure in the tank 40 becomes negative. At this time, since the PVA sponge 30 does not allow air to pass through, the check valve 31 is opened to take in air from outside. The water dropped from the PVA sponge 30 flows through the spill pipe 29 toward the tank 40 by this air,
Finally, it is collected in the tank 40. When such water circulation is repeated, the concentration of the residue in the water gradually increases, so if the amount of water decreases to some extent, discard the water and fill the tank with fresh tap water. Good.

By the way, in an environment where the temperature is high and the humidity is extremely low, there is a possibility that the water is excessively vaporized and the lower sheet 21 dries. In such a case, lower sheet 2
It is also possible to provide a sensor for detecting the degree of wetting at the lower end of 1 and provide a means for issuing an alarm when the lower sheet 21 dries, for example.

The method for preventing the precipitation of the residue is not limited to the circulation type as described above. For example, drain 2
Even if the water collected from the spill pipe 7 from the spill pipe 29 is stored in a separately provided drainage tank and periodically discarded, it is possible to prevent the residue from being deposited on the lower sheet 21. . The point is that all the water should not be vaporized on the lower sheet 21.

Next, the cooling operation of the cooling garment 1 will be described. The fan 23 is a sirocco fan.
b rotates in the direction of sucking air. The sucked air flows downward through a ventilation path formed between the lower sheet 21 and the upper sheet 22 and is discharged from a discharge port 22d provided in a lower part of the upper sheet 22. The water supplied to the front side of the lower sheet 21 is in close contact with the air flowing from the top to the bottom in the ventilation passage in the process of diffusing the surface. Due to the contact with the flowing air, the amount of water vaporized becomes much larger than usual, and evaporates actively in the flowing air. When water evaporates, 5 per cc
Since 80 calories of heat are removed from the surroundings as heat of vaporization, the lower sheet 21 in which water was present is cooled by the vaporization of water. Therefore, the heat radiated from the body of the wearer in close contact with the lower sheet 21 is absorbed by substantially the entire lower sheet 21 and the body of the wearer is effectively cooled.

As described above, since the cooling principle 1 has a high cooling effect based on the simple principle, the cooling garment 1 may be used in an indoor work site where a high-temperature heat source is nearby, such as a steel mill or a glass factory.
Alternatively, it is suitable for use at an outdoor work site in summer. In addition, the cooling garment 1 is suitable for cooling the general public in tropical and subtropical regions where developing countries are concentrated, since both the manufacturing cost and the running cost can be kept low.

Further, there are cases where a businessman must wear a tie and wear a jacket even in the middle of summer. In such a case, if the cooling suit of the present embodiment is worn under the outerwear, it is possible to spend a cool time. In this case, if a normal thing is worn as the outerwear, the suction port 22b and the discharge port 2
2d is closed by the jacket, and a sufficient cooling effect cannot be obtained.
Therefore, it is desirable to prepare a dedicated outerwear made of a material having high air permeability such as a mesh material at a portion corresponding to the suction port 22b or the discharge port 22d when worn.

When excessive heat is generated in the body, it is necessary to radiate this heat to the outside through the body surface. In this case, it is not necessary to radiate heat uniformly from the entire surface of the body, and a specific heat is not required. Even if the heat is radiated intensively from a part, the function of the body can be preserved, and even in such a case, the human can obtain comfort. This is in contrast to the fact that it is not enough to heat only a part of the body when it is cold, and it is necessary to heat the whole body as much as possible. Therefore, like the cooling suit 1 of the present embodiment,
Even when only the body is cooled by the four cooling sheets 20 before and after the form of the clothes is the best type, if the heat radiation amount is sufficient, it is possible to spend comfortably. Work efficiency can be maintained.

Next, a modified example will be described. FIG.
FIG. 8 is a front view showing the appearance of the cooling garment 101 of the present modification.
Is an enlarged view of a part of the tank belt 140. In the above-mentioned cooling garment 1, the hanging portion 11 serving as the tank 40 and the electric unit 41 is provided, and the hanging portion 11 is hung on a pants belt. On the other hand, in the cooling garment 101 of the present modification, a tank belt 140 in which the tank itself is formed in a belt shape is prepared, and this is wrapped around the body.

The tank belt 140 can be manufactured by blow molding polyethylene or the like. As shown in FIG. 8, the tank belt 140 is provided with a large number of cuts 141 so that the tank belt 140 can be easily wound around the body. The inside of the tank belt 140 is hollow,
Into this, about 500 cc of water can be injected.
On the tank belt 140, a battery 142, a volume 143 with a switch, a light emitting diode (LED) 144,
A pump (not shown), a control circuit (not shown), and the like are included.

At an appropriate position of the tank belt 140, a connection hole for a sewage pump, a jack for inserting a plug of a power cable, and the like are provided. Further, a bellows-shaped supply pipe 145 is provided so that water can be supplied without removing the tank belt 140 when water is low. When replenishing water, the tip of the replenishing pipe 145 is removed from the main body, and tap water is injected from here.

The tank belt 140 is integrated with the main body by connecting the tank belt 140 with several buttons. When the main body is worn in this state, the tank belt 14
The 0 is automatically wrapped around the torso and can then be secured around the torso by fastening the front buckle as with a normal belt. Therefore, the cooling clothes 101
The tank does not get in the way when you work with the garment. The structure of the main body of the cooling garment 101 is almost the same as that of the main body 10 of the above-described embodiment, and the cooling principle is also the same.

Since the cooling principle of the cooling garments 1 and 101 is as described above, the cooling effect is reduced in a high-temperature and high-humidity environment. For example, in an environment in which the ambient temperature is 36 ° C. or higher and the humidity is almost 100%, the water held in the lower sheet 21 does not evaporate with the above-described structure, and thus a cooling effect cannot be obtained. . Therefore,
In such a case, a sufficient cooling effect can be obtained by flowing low-humidity air or gas containing no moisture through the ventilation path.

FIG. 9 is a conceptual diagram showing a method of lowering the humidity of the air flowing through the ventilation path using a dehumidifier. Most commonly used silica gel can be used as the dehumidifier. As shown in FIG. 9, the dehumidifying section 5 filled with silica gel
0 is attached to the back of the cooling garments 1 and 101 and the like, and air 51 pressurized by a separately provided fan is sent into the dehumidifying section 50. Air 5 that has passed through the dehumidifying unit 50
2, since the inside is dehumidified by the silica gel, the humidity is sufficiently reduced. Originally, a sufficient cooling effect can be obtained by flowing a small amount of air through the ventilation part of the cooling sheet 20. Therefore, dehumidification of air enough to flow through the ventilation part is sufficiently possible only with the dehumidifying part 50 having such a structure. It is.

Silica gel has a property of generating heat when absorbing moisture. When the silica gel emits heat and becomes high temperature, the air passing therethrough is also warmed. Therefore, if the silica gel is passed through the ventilation passage as it is, the cooling effect is reduced. Therefore, as shown in FIG. 9, a large number of elongated holes 50a are provided in the case of the dehumidifying section 50, and outside air 55 is circulated through the holes 50a separately from the air flowing through the ventilation passage. Due to the air cooling effect of the outside air, the dehumidifying section 50 is cooled and the temperature rise of the silica gel is suppressed. Thereby, the temperature rise of the air flowing through the ventilation path can also be suppressed.

As a method of flowing a gas containing no water into the ventilation path, for example, a case for holding dry ice is provided on the back portion of the cooling garment 1, 101 or the like, and the dry ice loaded therein is sublimated. It is conceivable that the carbon dioxide gas generated in the cooling sheet 20 is caused to flow through the ventilation passage. Carbon dioxide gas generated by sublimation of dry ice has a concentration of almost 100% and contains almost no moisture. Therefore, when the air is passed through the air passage, the water held in the lower sheet 21 evaporates actively, and a sufficient cooling effect can be obtained.

Heretofore, a case has been described in which water is supplied to the lower sheet of the cooling sheet, air is flown through the ventilation passage in contact with the cooling sheet to promote vaporization, and the lower sheet is cooled. However, a sufficient cooling effect may be obtained simply by flowing air through the ventilation passage without supplying water.

The temperature around a human body is 36 ° C., which is the same as the body temperature in the vicinity of the body, but the temperature gradually decreases as the distance from the body increases. The manner of temperature change (temperature gradient) at this time is larger as the ambient temperature is lower, and is smaller as the ambient temperature is higher. A person feels cooler as the temperature gradient is larger, and feels hotter as the temperature gradient is smaller. When the ambient temperature rises to about 25 ° C. or higher, a person feels heat, but this temperature is sufficiently lower than the human body temperature. Therefore, when outside air of about 25 ° C. is passed through the ventilation path of the cooling garments 1 and 101, the temperature of a portion slightly away from the human body is forced to 25 ° C. This increases the temperature gradient near the body, so that the wearer feels cool. Accordingly, if the user feels the heat as it is, but the surrounding temperature is not extremely high, a sufficient cooling effect can be obtained by simply flowing air through the ventilation passage without supplying water. Therefore, the cooling garments 1 and 101 with the water supply portion removed are also sufficiently practical as simple cooling garments. In this case, the four vaporization sheets
It becomes a "ventilation sheet" that only allows air to flow. The technical scope of the present invention includes such a simple cooling suit.

The embodiment of the present invention has been described above. However, the present invention is not limited to the above embodiment, and various changes can be made within the scope of the invention.
Needless to say, they also belong to the technical scope of the present invention. For example, in the above embodiment, water was used as the liquid for vaporization. Water is the easiest liquid to use and has high safety. However, when a higher cooling capacity is required, for example, a volatile solution such as ethyl alcohol or a solution obtained by mixing the same with water can be used as a liquid for vaporization. Further, in the description of the above embodiment, the description has been made on the assumption that the clothing is worn on the upper body of a human, but this is applied to clothing worn on the lower body such as pants, for example, to cool the lower body. It is easy to transform into a structure that cools both the upper body and the lower body. further,
It is also possible to use a cooling suit to be worn by not only humans but also pets such as dogs.

[0052]

As described above, the cooling garment of the present invention has a simple structure, has a sufficient cooling capacity, and consumes very little power. Therefore, the present invention is extremely useful in mid-summer outdoors where air conditioners cannot be used, indoor work sites such as factories having a nearby heat source, and regions where air conditioners are not widely used such as developing countries.
