Description

  The present invention relates to a cooling garment that cools a human body by circulating outside air in parallel with the body.

  One can think of it as a very inefficient working device that consumes food, performs life support activities and work, and generates heat in response. Due to the inefficiency, most of the calories ingested become heat, and in order to maintain normal body temperature, a large amount of heat radiation corresponding to the amount of work at that time is required. For this reason, people have the physiological function of cooling their bodies by sweating. In other words, the amount of heat that is physiologically required is determined according to the amount of work, and sweat corresponding to this is drawn out.If all the sweat is vaporized, the optimum heat dissipation for the person's current situation is achieved. Done. The amount of sweat that corresponds to the amount of heat released will of course not be calculated uniquely by the brain. Will not be too cold. Therefore, as a result, the amount of sweat corresponding to the required heat dissipation amount is discharged.

  However, if sweat cannot be vaporized due to conditions such as temperature, humidity, presence / absence of wind, work amount, etc., the necessary heat dissipation will not be obtained, and it will continue to produce wasteful liquid sweat that is not vaporized and uncomfortable. Not only will it be, it will also suffer from physiological damage. This requires the help of cooling clothing. Among cooling clothing, the type that cools the human body by circulating outside air in parallel with the human body (hereinafter also referred to as air-flowing cooling clothing) uses outside air without using a cooling device such as a compressor. Therefore, it is possible to perform cooling that is gentle to the human body with low power consumption.

  By the way, the conventional air circulation type cooling garment can vaporize the sweat produced when a person is performing a normal operation, and therefore, the wearer of the cooling garment can be appropriately cooled. However, when sweating a large amount of work in a high temperature environment or heavy work, the sweat was not sufficiently vaporized. That is, the conventional air circulation type cooling garment cannot be used in such a severe use environment. Further, in the conventional air flow type cooling garment, a spacer is provided between the cooling garment and the undergarment in order to secure an air flow passage. For this reason, the conventional air circulation type cooling garment has a complicated structure.

  In addition, it is desirable that the cooling garment used in a situation where a large amount of sweat is sweated be easily washed because it becomes dirty with sweat.

International Publication No. 02/067708 Pamphlet

  The present invention has been made based on the above circumstances, and an object thereof is to provide a cooling garment having a simple structure and capable of reliably vaporizing a large amount of sweat.

  In addition to the above object, an object of the present invention is to provide a cooling garment that can be easily washed.

In order to achieve the above object, an invention according to claim 1 is provided with one or a plurality of air intake ports for taking in external air, blades and a motor for rotating the blades, and provided on the front surface. One or a plurality of parallel wind generating means for generating parallel wind substantially parallel to the body by taking in air from the suction port and blowing out air in a substantially side direction from a parallel wind sending part provided on the side surface ; A guide sheet that also serves as clothes for guiding the parallel wind generated by the parallel wind generating means in parallel to the body, one or a plurality of air outlets that discharge the parallel wind to the outside, and the guide sheet Power supply means for supplying power to the parallel wind generating means detachably provided , the air intake port is formed in the guide sheet, and the parallel wind generating means The air inlet of the generating means and the guide The parallel wind generating section of the parallel wind generating means is detachably provided inside the guide sheet so that the air intake port formed in the guide is opposed to the air intake port. , by the parallel air generating means, a total of about 10 m ³ / h to 500m ³ / h of air the guiding sheet - by blowing between the bets and the undergarment or body, the guide sheet - DOO and underwear or body between in the positive pressure and form an air flow space together with further discharged by circulating air water vapor from sweat to the outside the air circulation space, fed constantly fresh outside air, sweat can evaporate It is characterized by greatly expanding the conditions.

  The cooling garment of the present invention can cool the human body by greatly expanding the effective range of the human physiological cooling function by flowing a large amount of air between the underwear or the human body and the guide sheet.

  First, the cooling principle of the present invention will be described. In a state where a person sweats a large amount of sweat, specifically, when the sweat is blotting in the underwear, the humidity in the vicinity of the underwear or the skin becomes almost 100%, and the sweat that comes out later cannot evaporate. On the other hand, for example, even when the humidity of the outside air is 90%, sweat can be evaporated by flowing a large amount of air. In general, when the humidity is extremely high, the temperature is not so high, and when the temperature is extremely high, the humidity is low. The temperature obtained by the evaporation of sweat is determined by the wet bulb temperature of the wet and dry thermometer.For example, if the temperature is 50 ° C and the humidity is 20%, the body temperature can be lowered to 28 ° C by vaporizing the sweat. Even if it can be drained sufficiently, the sweat can be completely evaporated.

In terms of body cooling by evaporation, sweat can be divided into the following three types.
(1) Immediate sweat: The sweat that evaporates at the same time as it leaves the body and cools the body immediately.
(2) Delayed sweat: Sweat that comes out of the body in a liquid state, wets the underwear, and does not cool immediately when the body is needed, but evaporates later when the wind blows. Cool the body.
(3) Ineffective sweat: Sweat that falls from the body and does not cool the body by evaporation.
When inactive sweat is out, the physiological cooling function is not in time, the body temperature continues to rise, and it cannot continue that way.

  When there is no ineffective sweat but slow-acting sweat, body temperature rises and returns to normal. In this state, it feels muggy and uncomfortable, but it is possible to continue as it is. It is this slow-acting sweat that makes you feel cool when you hit the wind while sweating and your underwear wet. Furthermore, when only immediate sweat is used, the sweat evaporates immediately, so there is no cooling delay, there is no change in body temperature, and it is a very comfortable state and does not feel the heat.

  The heat and cold are not absolute, it depends on the person's current exercise state, temperature, humidity, presence of wind, etc. Even if the temperature is high, if the sweat is all effective immediately, you will not feel the heat . Therefore, if a large amount of wind is allowed to flow in parallel with the body through cooling clothing, the sweat that has come out can be evaporated immediately, and all the sweating controlled by the brain can be instantly sweated. As a result, the human body is cooled appropriately. be able to. That is, by wearing cooling clothing and flowing a large amount of air in parallel with the body, the range of conditions for vaporizing sweat from the human body can be greatly expanded.

I put on a cooling garment that can flow a large amount of wind (30m ³ / H), put on a cooling cushion of the same principle, put a cooling cap on my head, and conducted a practical test of office work. However, the limit temperature at which people feel hotter varies, but those who are not very fat did not feel the difference at room temperature of 25 ° C or 40 ° C. It is confirmed that if you feel hot, you will experience liquid sweat on a daily basis, but conversely, if you don't get liquid sweat and you have only immediate sweat, it's not hot. Note that no matter how strong the wind parallel to the body is, the wind is not directly applied to the body, so that it does not give the user the unpleasant feeling as when the raw warm wind from the electric fan hits.

  The state in which humans feel most comfortable is a state in which sweat is generated for heat dissipation, and the sweat evaporates immediately, that is, a state in which a physiological cooling function (cooler) is included. As a condition for realizing this, it is necessary that the outside air temperature is high and sweat is generated, and that the outside air is constantly flowed in parallel with the body to remove the moisture to the outside.

As described above, the present invention greatly expands the effective range of the physiological cooling function and cools the human body by flowing a large amount of wind in parallel with the human body even in a severe environment where invalid sweat occurs. It uses the cooling principle to do.
[First Embodiment]
The best mode for carrying out the present invention will be described below with reference to the drawings. In the first embodiment, the cooling garment according to the present invention is applied to a short-sleeve outerwear for work clothes. Fig.1 (a) is a schematic front view when the cooling garment which is 1st Embodiment of this invention is dressed, (b) is the schematic rear view. As shown in FIG. 1, the cooling garment 1 of the first embodiment includes a garment 2 formed in the shape of a short-sleeve jacket and serving as a guide sheet (the meaning of guidance will be described later) with little air leakage, A parallel wind generator 3 provided on the left and right sides for taking in external air and generating a flow of air parallel to the body between the garment 2 and the undergarment or the body, and an air outlet portion serving as an air outlet 4, an air intake 2 a that is an air inlet formed in the garment 2, an air leakage prevention means 5 for preventing air leakage from the hem of the garment 2, and a front portion of the garment 2. Fasteners 6 are provided.

In the present embodiment, two parallel wind generators 3 are provided. When power is supplied from a cord (not shown) that is detachably provided on the garment 2 and a power source (battery) (not shown), external air is supplied. It is designed to be sucked into clothes. The total amount of air blown by the two parallel wind generators 3 is set to about 10 m ³ / H. Hereinafter, the parallel wind generator 3 may be simply referred to as a fan 3. Moreover, as the air outlet part 4 of the cooling clothes of this embodiment, there are a gap between the collar part of the clothes and the human body, and a gap between the cuffs and the arms. The air leakage prevention means 5 prevents air leakage from the skirt by, for example, passing a string through the hem of the garment and strongly tying both ends of the string in front of the garment.

Since the first embodiment is configured as described above, when the parallel wind generator 3 is driven, about 10 m ³ / H of air enters the cooling garment 1 through the air intake 2a, and the cooling garment 1 near the parallel wind generator 3 becomes a positive pressure and the clothes 2 swell, creating a space between the clothes that also serve as a guide sheet and underwear, creating a wind flow that wraps around the body, and the end of the cooling clothes Air goes out from the air outlet part 4 which is a part. The garment 2 is referred to as a guide sheet here because the garment 2 also serves as a guide for creating an air flow that wraps around the body. It is desirable that it is made of a material and devised in terms of shape so that a larger air flow is possible where the body should be cooled.

  By creating a large air flow parallel to the body as described above, the effective range of the physiological cooling function of the human body due to evaporation of sweat can be greatly expanded. The problem due to can be fundamentally solved.

Next, points when the cooling garment of the present invention is applied to work clothes will be described in detail. As a general requirement for work clothes,
(1) Inexpensive
(2) Large cooling capacity
(3) Ensure that workability is not impaired,
(4) Since the frequency of washing is high, electrical components may be easily removed. On the other hand, in work clothes, function is not very important.

  First, (1) it is inexpensive, but conventional cooling garments require a spacer to create an air flow path in advance to create an air flow parallel to the body, and the spacer is the cost of the entire cooling garment. The percentage of On the other hand, in the cooling garment of this embodiment, a large amount of air is poured into the garment to form a space for air to flow between the body and the garment by the pressure of the air, thereby using a spacer. It is realized that the air flow passage is formed without the need.

  Increasing the cooling capacity in (2) can be realized by using a large fan and using a fan motor with high efficiency. As a motor for this purpose, a brush motor is optimal in consideration of cost. (3) and (4) will be described later.

  Next, the parallel wind generator of this embodiment will be described. FIG. 2 is a schematic side view of the vicinity of the parallel wind generator attached to the garment 2. FIG. 3A is a schematic front view of a fan case of the parallel wind generator, and FIG. 3B is a schematic side view with a part thereof cut away. 4A is a schematic front view of a side flow fan of the parallel wind generator, and FIG. 4B is a schematic cross-sectional view taken along the line AA ′. The parallel wind generator 3 according to the present embodiment includes a side flow fan 3 a, an overcooling prevention cloth 12, and a fan case 31.

As shown in FIG. 3, the fan case 31 includes a front fan guard 7a formed at the air intake port of the fan, an internal side fan guard 7b formed at the parallel wind sending portion, a flange portion 8, A bottom portion 9 and a magic tape (registered trademark) 8 a attached to the flange portion 8 are provided. Front fan guard 7a and the inner side fan guard 7b of this embodiment is that is formed by the columnar members, the fan guard may be formed in a grid shape. In particular, a fan having a large blowing capacity as in the present embodiment has a large rotational energy of the impeller 10 and may be injured when a finger or the like touches the impeller 10, so it is necessary to cover the fan with a fan guard. There is. Further, depending on the work content, frequent washing is required, and a magic tape is provided on the flange portion so that the fan can be easily attached and detached during washing. Also, a donut-shaped magic tape 8b is provided on the back side of the garment 2 around the air intake port 2a. And Velcro 8a provided on the air inlet of the fan 3, the Velcro 8b provided in the air inlet of the garment 2, a fan 3 can be freely attached removably to the garment 2. Note that the means for attaching and detaching the fan 3 is not limited to the magic tape, and various methods are conceivable.

  As shown in FIG. 4, the side flow fan 3 a of this embodiment includes an impeller 10 and a motor 11. The impeller 10 includes a rotating body 10b and a large number of blades 10a that are formed substantially perpendicular to the rotating surface of the rotating body 10b in the periphery of the rotating body 10b. Therefore, when the impeller 10 is rotated by the motor 11, the air is taken in from the front as shown by the arrow and sucked out in the side direction. In the present embodiment, such a fan that sends wind is referred to as a side flow fan.

  The over-cooling prevention cloth 12 is made of a cloth having high heat insulation and is attached to the bottom portion 9 of the fan case 31. The overcooling prevention cloth 12 has an outer shape that is, for example, about 5 to 15 cm larger than the outer shape of the fan case 31. The direction of the wind blown out by the fan 3 is not completely parallel to the body due to the inertia of the sucked air as shown by the arrow in FIG. End up. In particular, the outside air temperature is not so high, but when the humidity is high, it is necessary to wear the cooling clothing of this embodiment in order to eliminate the sultry heat, but if the temperature difference between air and body temperature is large, it is directly The body may be partially cooled around the fan 3 where the outside air is blown to the body. In order to prevent this, in the present embodiment, an overcooling prevention cloth 12 made of a cloth having high heat insulation is provided.

  Further, the cooling garment 1 of the present embodiment includes a hanging means 14. FIG. 5 is a schematic cross-sectional view showing the relationship among the garment 2, the fan 3 and the underwear 13. The suspension means 14 of the present embodiment has one end attached to the shoulder of the garment 2 and the other end attached to the fan. Since the fan 3 having a large air blowing capacity is heavy, the fan 3 tilts as shown in FIG. 1A only by attaching it to the clothes with the magic tape, which is not good in appearance but also the function of the cooling clothes itself. It will decline. For this reason, in this embodiment, as shown in FIG. 2B, the fan 3 is suspended from above by the suspending means 14 such as a string from the upper part of the clothes 2. In addition, this string may be a round bar shape or a band shape.

According to the present embodiment, a large amount of wind of about 10 m ³ / H blown in parallel between the underwear 13 and the clothes 2 by the parallel wind generating device 3 is a space between the clothes 2 and the underwear or body. The air flow passage is automatically formed by inflating with positive pressure and discharged from the air outlet 4 formed at the end of the clothes. As described above, the cooling garment according to the present embodiment can form the air flow passage without using the spacer for securing the air flow passage, so that the structure becomes simple and can be made at low cost.

In addition, by devising the shape of clothing, the air resistance at the air outlet, and the weight of clothing, air can be circulated without using a spacer even with an air volume of about 5 m ³ / H. In this case, from the viewpoint of cost and cooling performance, it is desirable to secure the air flow passage more securely by using a small spacer at a required place. For example, a sponge or the like can be used as the spacer in this case. Moreover, the upper limit of the total ventilation volume by a parallel wind generator is about 500 m < ³ > / H. If it is larger than this, the parallel wind generator becomes large and the workability deteriorates, which is not realistic. The clothing is referred to as a guide sheet because the clothing itself also serves to guide the parallel wind generated by the parallel wind generator to the air outlet 4 that is an air outlet while being kept parallel to the body. . As a condition for this, it is only necessary to use a material with less air leakage for the garment and to easily create a space between the undergarment and the garment with a small pressure. Moreover, it is not always necessary to circulate air over the entire body covered with clothes, and the shape and the like may be devised so that air circulates in a place where sweat easily occurs. In particular, it is generally said that it is better not to cool the abdomen. The air leakage prevention means 5 configured at the hem prevents air from leaking from the hem, and the entire air blown from the lower back is formed at the end via the back, chest, armpit, etc. Although it is necessary for discharging from the air outlet portion 4 which is the outlet of the airflow, it may be omitted depending on the mounting position of the parallel wind generator and the purpose of use of the cooling garment itself.
[Second Embodiment]
Next, a second embodiment of the present invention will be described with reference to the drawings. In the second embodiment, the present invention is applied to work clothes having a higher cooling capacity than the cooling clothes of the first embodiment. The blowing capacity of the second embodiment is about 20 m ³ / H, which is twice that of the first embodiment. The main difference between the second embodiment and the first embodiment is that, in the second embodiment, a propeller is used instead of an impeller as a blade of the parallel wind generator, and air is used as an air outlet that is an air outlet. A new air outlet portion provided with a permeable sheet and a fixing belt as a fixing means for preventing a large fan from being shaken by the movement of the body are provided. Other configurations are the same as those of the first embodiment. Therefore, in the second embodiment, components having the same functions as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  FIG. 6A is a schematic front view when the cooling garment of the second embodiment is viewed from the front, and FIG. 6B is a schematic rear view when the cooling garment is viewed from the back. An air permeable sheet 15, which is a cloth having a large air permeability, is attached to the upper back of the cooling garment according to the present embodiment instead of the clothes garment, which also constitutes the air outlet 4. Below, in order to distinguish this air outlet part from the air outlet part 4 of 1st Embodiment, it calls a 2nd air outlet part, and the air outlet part of 1st Embodiment is called a 1st air outlet part.

  FIG. 7A is a schematic side view of a fan used in the second embodiment, and FIG. 7B is a schematic side view thereof. The fan of the second embodiment is different from the fan of the first embodiment in that a prober 17 is used instead of the impeller for the blade used. The prober 17 rotates in the direction in which the outside air is taken in by the motor 11, takes in the outside air, and feeds the wind perpendicular to the rotation surface of the prober, but hits the parallel wind conversion plate (parallel wind converting means) 19 as indicated by an arrow. The direction is changed parallel to the rotation surface of the prober, and the wind is parallel to the body. In the present embodiment, the bottom 9 of the fan case also serves as the parallel wind conversion plate 19. Also in this embodiment, although not shown, an overcooling prevention means 12 is provided.

  Here, an interval H that is about 1/5 of the diameter of the prober is required between the lower end of the prober and the parallel wind conversion plate 19, and if it is smaller than this, the amount of blown air is significantly reduced. At least 1/10 is required. Therefore, although the thickness of the fan becomes thicker than that of the side flow fan used in the first embodiment, there is an advantage that the power consumption for generating the same air volume is smaller than that of the side flow fan. Depending on the application, for example, when the air volume may be small, the interval H may be set to zero.

  FIG. 8 is a schematic view showing a state in which the fastener 6 of the cooling garment of the present embodiment is opened and the fixing belt 16 to which the fan 3 is attached is developed. The fixing belt 16 of this embodiment is for attaching the two fans 3 in close contact with the human body. A power source (battery) and a cord (not shown) are detachably attached to clothes as in the first embodiment. A string 21 as a fixing belt connecting means is attached to both ends of the fixing belt 16. The cooling garment according to the present embodiment that requires a large cooling capacity requires a large fan and increases the weight. When a large and heavy fan is attached to the garment 2, not only does the fan tilt and the performance decreases, but when the user moves around, the fan shakes and deteriorates workability. The fixing belt 16 is provided as a countermeasure for this, and the fan 3 is brought into close contact with the body to solve the above-described problems. Note that the fixing belt 16 may be fixed to the clothes 2 at some places, or may be left free without being fixed to the clothes 2. Even when the fixing belt 16 is free, the fan is fixed to the clothes by the fan magic tape.

  FIG. 9 is a view showing a modification of the second embodiment. FIG. 9A is a schematic front view of a mixed flow fan according to this modification, and FIG. 9B is a schematic cross-sectional view taken along the line BB ′. It is. In FIG. 9, the fan case 31 is omitted to simplify the drawing. In this modification, blades 20 of a mixed flow fan are used instead of the propeller. The structure of the blades of the mixed flow fan is an intermediate structure between the side flow fan and the propeller fan, and is also characteristically intermediate. As shown by the arrow in FIG. 9, air is taken in from the front and is sent obliquely backward. . Therefore, even when this type of blade is used, the space H between the lower portion of the blade and the parallel wind conversion plate is necessary, but the required space H is large when the shape of the blade is close to the shape of the propeller. It becomes smaller when it is close to the shape of the car. In this case as well, the interval H may be set to 0, for example, when the air volume may be small according to the application.

  When using the cooling garment of the present embodiment, after passing the hand through the sleeve and before closing the fastener 6, the cord 21 attached to the front end of the fixing belt 16 is tied, the fan is fixed to the body, and then the fastener is attached. Close. Of course, the connecting method of the fixing belt 16 is not limited to the string, and a magic tape or the like may be used.

According to this embodiment, the air blown into the clothes (guide sheet) by the parallel wind generator is guided in parallel with the body by the guide sheet as in the first embodiment, and is an air outlet portion that is an air outlet. Is discharged to the outside. Here, in the present embodiment, a part of the upper back of the garment is replaced with an air permeable sheet, and a second air outlet is formed in addition to the first air outlet. Generally, around the neck of work clothes and the like, the front part is wide open, but the back part is often in close contact with the neck. In such a configuration, the function of the back neck around the neck as an air outlet is not sufficient, so that there is not much air flow in the upper part of the back. In order to assist this, by replacing a part of the cloth on the upper back with a sheet having good air permeability, it is possible to function as an air outlet and improve the air flow rate on the upper back. Other operations and effects of this embodiment are the same as those of the first embodiment.
[Third Embodiment]
Next, a third embodiment of the present invention will be described. The third embodiment is different from the first and second embodiments in that not only a fan but also a power source (battery) and a cord are attached on the fixed belt. Other points are the same as in the second embodiment. Therefore, in this embodiment, those having the same functions as those in the first and second embodiments are denoted by the same reference numerals, and detailed description thereof is omitted. FIG. 10A is a schematic view showing a state in which the fixed belt 160 of the present embodiment is developed. The fixing belt 160 of this embodiment has a width larger than the diameter of the fan 3, and two fans 3, a power supply code 32, and a power supply 33 are detachably attached. Therefore, it can be said that the fixing belt 160 is obtained by removing the guide sheet (clothing) from the cooling clothes. FIG. 2B is an enlarged schematic view of the vicinity of the air intake 2a of the clothes to which the fixing belt 160 is attached. A magic tape 8b is provided in a donut shape around the air intake port 2a. Further, the magic tape 8a is also provided on the flange portion 8 of the fan 3 as described above. The fixing belt 160 according to the present embodiment is attached to clothes by closely contacting the magic tape 8a of the fixing belt 160 and the magic tape 8a of the fan 3 and bonding them.

According to the present embodiment, when washing the cooling garment, if the fixing belt 160 is removed from the garment, the fan, the power source, and the cord can be removed at the same time, which saves time.
Further, in this embodiment, if the fixing belt 160 is attached to the garment 2, the form is almost the same as that of the second embodiment, and the manner of clothing is the same as that of the second embodiment. As described above, the greatest advantage of the third embodiment is that the electrical components can be easily attached and detached at the time of washing, etc., and since all the electrical components are fixed on the belt, handling is easy. And fewer failures. Since the fixing belt 160 itself cannot be washed, it is desirable that the fixing belt 160 be made of a material that is difficult to get dirty and that can easily be wiped off even if it is dirty. In particular, a material that does not absorb sweat is desirable, and it is desirable to perform antibacterial processing. Further, the attachment / detachment of the fixing belt to / from the garment 2 is not limited to the method using the magic tape, and any method may be used as long as there is no large air leakage between the fan attached to the fixing belt and the garment. . The other operations and effects of this embodiment are the same as those of the second embodiment.

The fan mounted on the fixed belt may have a front fan guard, or a front fan guard may be formed on the clothes side, and the fan may be a fan without the front fan guard. In this case, for example, a mesh or the like may be put on the air intake port 2a of the clothes to replace the front fan guard. Further, a lid part 200 having a lid fan guard 201, a flange part 202, and a cylindrical part 203 formed in a tapered shape is formed as shown in FIG. 11, and as shown in FIG. 12, the cylindrical part 203 of the lid part 200 is formed. Is inserted inside the flange portion of the fan 3, and the clothing around the air intake port 2 a is sandwiched between the flange portion 202 of the lid portion 200 and the flange portion 8 of the fan 3, thereby connecting the lid portion 200 and the fan 3. The fixing belt 160 may be attached to the clothes. Note that the method of joining the lid portion and the fan is not limited to the above method, and any joining method can be used as long as the fixing belt 160 can be attached to the clothing by sandwiching the clothing between them. But you can. Moreover, in FIG. 12, the blade | wing inside a fan case is abbreviate | omitted and drawn in order to simplify a figure.
[Other Embodiments]
The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the gist. For example, in each of the above-described embodiments, the case where the cooling garment is a work jacket has been described. However, the cooling garment of the present invention is integrally formed with a jacket and pants, for example, as shown in FIG. It may be a worn outfit. In this case, the gap between the foot hem and the foot of the clothes also becomes the air outlet 4. In the case of this embodiment, since it is a clothes, the air leakage prevention means 5 is not necessary.

  Moreover, in each said embodiment, in order to prevent an air leak, the fastener 6 which opens and closes clothes was provided, However, This invention is not limited to this, What is the method with few air leaks? Such a method may be used. Furthermore, conversely, air may leak to some extent, and the open / close portion of the clothes may be one of the air outlet portions (for example, a button is used instead of a fastener).

  As described in the second embodiment, when a prober fan is used as the parallel wind generator, the thickness of the prober can be reduced by increasing the number of blades, thereby reducing the thickness of the entire fan. In this case, the fan does not necessarily have to be attached to the inside of the clothes, and may be attached to the outside of the clothes.

  Furthermore, when using blades of a prober or a mixed flow fan, a parallel wind conversion plate is provided as a parallel wind conversion device at a distance H from the lower end of the blade, but the parallel wind conversion device is not limited to a plate shape, Rather, it is desirable to use a parallel wind conversion plate 190 having a three-dimensional shape capable of converting the wind direction into smooth, for example, a substantially conical shape as shown in FIG. Further, if a gap H is provided between the prober and the underwear, a parallel wind conversion plate or the like is not necessary, and the body and underwear play the same role as the parallel wind conversion plate. That is, the interval H itself can be said to be parallel wind conversion means. Further, the interval H may not be provided in advance, but may be automatically provided by the pressure of the wind blown on the body. In this case, the parallel wind converting means is formed by the clothes and the fan.

  Furthermore, the shape of the cloth is not limited to the front opening as in each of the above-described embodiments, and may be a T-shirt, for example. In the case of T-shirts, the air outlet is around the neck, sleeves, and hem.

  Furthermore, the guide sheet (clothing) may be air permeable to some extent depending on the purpose, as long as the fan blows a large amount of air and allows sufficient parallel wind to flow. In this case, since the pressure around the fan is particularly high, the effect is improved if the air permeability is small. In the case of long sleeves, depending on the shape of the cooling garment, the parallel wind may not flow so much into the sleeve. In this case, it is better to use an air-permeable cloth for the sleeve when the arm is moved. There are cases where it is good to win.

  Further, the power supply means is not limited to a battery, and may be a commercial power supply. For example, when used when working while sitting almost at one place, power may be supplied to the cooling garment of the present invention while the cord from the commercial power supply is connected.

  As described above, according to the present invention, by flowing a large amount of air in parallel with the human body, the effective range of the physiological cooling function of the human body can be greatly expanded.
