Description

Air-conditioning protective clothing

The present invention relates to an air-conditioning protective clothing having a function of an air-conditioning clothing that cools the body by generating a flow of air substantially parallel to the surface of the body or underwear.

In recent years, air-conditioning clothing that cools the body has been put into practical use and is rapidly spreading. FIG. 10A is a schematic front view of a conventional air-conditioning garment, and FIG. 10B is a schematic back view of the air-conditioning garment. The conventional air-conditioning garment has power applied to the clothing main body 110 sewn from a material having a small air permeability, the two

fans

120 and 120 attached to the lower side of the clothing main body 110, and the two

fans

120 and 120. A power supply device (not shown) for supplying and a power supply cable (not shown) for electrically connecting the power supply device and the two

fans

120 and 120 are provided. When the

fans

120 and 120 are operated, a large amount of air is taken into the clothing main body 110 from the

fans

120 and 120. The taken-in air flows upward along the surface of the body or the undergarment in the space between the clothing main body 110 and the body or the undergarment, and is discharged to the outside, for example, around the collar or the cuffs. Here, the periphery of the collar and the cuffs serve as the air discharge unit 130. The air evaporates sweat that has come out of the body while flowing in the space between the clothing main body 110 and the body or underwear, and the body is cooled by heat of vaporization when the air evaporates (see, for example, Patent Document 1). ).

On the other hand, protective clothing such as chemical protective clothing that prevents harmful substances from coming into contact with the skin has a function of blocking outside air. For this reason, if the protective clothing is used when the outside air temperature is high, the user's body gets steamed. Generally, as a material for protective clothing, a sheet-like material having moisture permeability is used, but even if a sheet-like material having sufficient moisture permeability is used and the protective clothing has sufficient water vapor permeability, Since the protective clothing is not breathable, the user's body quickly gets steamed, and it is difficult for the user to work for a long time while wearing the protective clothing when the outside air temperature is high. Therefore, the realization of air-conditioning protective clothing that combines the function as protective clothing that blocks outside air and the function as air-conditioning clothing that cools the body by introducing outside air into the clothing body, which is a function that contradicts this function. Is anxious.

Republished Patent No. WO2005-063065

However, air conditioning protective clothing cannot be realized simply by attaching a fan to the protective clothing. This is because the protective clothing fitted with the fan takes in harmful substances from the fan as well as the outside air into the protective clothing, and does not function as protective clothing at all. In addition, in order to add a function as an air-conditioning garment to the protective garment, it is necessary to provide the protective garment with an air discharge unit that discharges the air taken into the protective garment to the outside. Furthermore, in order to add a function as an air-conditioning garment to the protective clothing, it is necessary to take in at least 4 liters of air per second into the protective clothing. Thus, there are a number of problems in realizing air-conditioning protective clothing.

The present invention has been made based on the above circumstances, and an object thereof is to provide an air-conditioning protective clothing having a simple configuration having a function as an air-conditioning clothing without impairing the function as the protective clothing.

In order to achieve the above object, an air-conditioning protective suit according to the present invention is made of a sheet-like material having a small air permeability or a non-air-permeable material, and one or a plurality of opening holes formed in a predetermined portion of the sheet-like material. One or a plurality of blasts that take in air from the outside and are forced into the space between the clothes body and the body or underwear, and attached to one or more openings. Means, a filter for removing a specific substance in the air having a peripheral end fixed to the back side of the clothing body so as to surround the air blowing means from the back side of the clothing body, and the clothing body excluding the vicinity of the opening hole To supply electric power to a plurality of air discharge units provided in a predetermined part of the air for discharging the air flowing through the space between the clothing body and the body or underwear to the outside, and one or a plurality of air blowing means Power supply means and one or more power supply means A power cable electrically connected to the blowing means, and driving one or more blowing means to take external air into the clothing body from the one or more blowing means, A positive pressure is used to form an air flow path between the body of clothing and the body or undergarment, and air from which a specific substance has been removed by the filter is circulated in the air flow path to be externally provided from a plurality of air discharge units. When the air flowing through the air flow passage evaporates the sweat from the body, the body is cooled by the heat of vaporization.

In the air-conditioning protective garment according to the present invention, the filter is arranged so as to surround the air blowing means from the back side of the clothing body, and the peripheral end of the filter is fixed to the back side of the clothing body, whereby the air intake of the air blowing means is used as a filter. Since it is possible to use one having a larger surface area compared to the area of the insert portion, it is possible to improve the collection efficiency of the filter and prevent a specific substance such as a harmful substance from adhering to the body or underwear. At the same time, a large amount of air can be taken in between the clothing body and the body or underwear through the filter. In addition, by taking in air from the blowing means, the pressure in the clothing body becomes positive, and an air flow passage is automatically formed between the clothing body and the body or underwear, and even the cuffs of the clothing body Even if there is a gap in the outer space, external air contaminated from the gap does not enter the clothing body, and thus the protective performance can be improved. Furthermore, air that has been freed of a specific substance, for example, a harmful substance, is circulated through the air flow passage by the filter and discharged from a plurality of air discharge portions, so that the air flowing through the air flow passage is discharged from the body. The user's body can be cooled by the vaporization heat generated when the sweat is vaporized.

In the air-conditioning protective garment according to the present invention, a filter having a large surface area is disposed so as to surround the air blowing means from the back side of the clothing body, and the peripheral end of the filter is fixed to the back side of the clothing body, thereby capturing the filter. Improves collection efficiency, prevents specific substances such as harmful substances from adhering to the body and underwear, and takes in a large amount of air between the clothing body and the body or underwear through a filter. Can do. In addition, the air from which a specific substance, for example, a harmful substance has been removed by the filter, is circulated in the air flow passage and discharged to the outside from the plurality of air discharge portions, so that the air flowing in the air flow passage is discharged from the body. The user's body can be cooled by the vaporization heat generated when the sweat is vaporized. As described above, the air-conditioning protective clothing of the present invention has a simple configuration and a function as a protective clothing and a function as an air-conditioning clothing.

The air-conditioning protective clothing 1 of this embodiment is a protective clothing having the function of air-conditioning clothing. As shown in FIGS. 1 and 2, the clothing main body 10, the two fans (blower means) 20, 20, and the filter 30, a plurality of air discharge units 40, a power supply means 50, a power supply cable 60, and a spacing means 70 described later. The main points of the air-conditioning protective clothing 1 that are different from ordinary protective clothing are that the

fans

20 and 20 are attached to the left and right of the rear side of the clothing body 10 and the vicinity of the

fans

20 and 20. A plurality of air discharge portions 40 are provided at predetermined portions of the clothing body 10 to be removed.

The clothing body 10 is made of a sheet material that is small or non-breathable. Here, a nonwoven fabric is used as the sheet material. This is the same as ordinary protective clothing. Moreover, in this embodiment, the clothing main body 10 is continuously formed in the shape of clothing. That is, the clothing body 10 can cover the upper body and the lower body, and can cover the head with the hood. Further, a fastener (opening / closing means) 11 is provided at the front of the clothing body 10. The fastener 11 is for opening and closing the front part when the clothes body 10 is worn.

A stretchable member such as rubber, for example, is provided in a portion corresponding to the wrist (cuff portion) and a portion corresponding to the ankle (hem portion) of the clothing body 10. As a result, the cuff portion and the hem portion of the clothing main body 10 are narrowed down and come into close contact with the body, so that outside air can be prevented from entering the clothing main body 10 from the cuff portion and the hem portion. In addition, opening holes are formed in predetermined portions of the clothing body 10, specifically, portions corresponding to the waist and on the left and right sides. The fan 20 is attached to the opening hole. That is, the portion of the clothing body 10 around the opening hole is a fan mounting portion.

The fan 20 takes in air from the outside and forcibly generates an air flow in the space between the clothing body 10 and the body or underwear. The fan 20 is attached to the fan attachment portion of the clothing body 10. FIG. 3A is a schematic front view of the fan 20 in the air-conditioning protective clothing of this embodiment, and FIG. 3B is a schematic side view of the fan 20. FIG. 4A is a schematic front view of a fan mounting portion in the air-conditioning protective clothing of this embodiment, and FIG. 4B is a schematic cross-sectional view in the direction of arrow AA of the fan mounting portion. As shown in FIG. 3, the fan 20 includes an air intake part 21, a flange 22, and a folder part 23.

The air intake part 21 is composed of a plurality of rod-like parts and ring-like parts and has sufficient air permeability. The air intake portion 21 serves as an air intake port and also serves as a finger guard that protects the finger from the rotating propeller so that no finger or the like enters from the outside. A flange 22 is connected to the outer edge of the air intake portion 21. The outer shape of the flange 22 is rectangular. A folder portion 23 is connected to the lower portion of the flange 22. The folder part 23 accommodates a motor (not shown) and a propeller (not shown), and has a cylindrical tubular part 231 and an air discharge part 232 connected to the lower side of the tubular part 231. The propeller is attached to the rotating shaft of the motor. The air discharge part 232 is composed of a plurality of rod-like parts and ring-like parts and has sufficient air permeability. An input terminal 24 for supplying electric power to the motor is provided on the lower side of the folder portion 23. When power is supplied to the input terminal 24, the propeller rotates and air is taken into the folder part 23 from the air taking part 21 and discharged from the air releasing part 232.

Moreover, the fan attachment part 13 is formed in the part of the clothing main body 10 around the opening hole 12, as shown in FIG. Here, the opening hole 12 has an outer diameter that is the same as or slightly larger than the outer diameter of the cylindrical portion 231 of the fan 20. The fan mounting portion 13 includes a rectangular frame plate 131 and an adhesive tape 132. The outer shape of the frame plate 131 is substantially the same as the outer shape of the flange 22. The frame plate 131 is a part of the clothing main body 10 around the opening hole 12 and is attached to the surface side of the clothing main body 10. An adhesive tape 132 is provided on the upper surface of the frame plate 131. The fan 20 is attached to the clothing body 10 by bonding the lower surface of the flange 22 of the fan 20 to the frame body 131 using the adhesive tape 132.

Next, a procedure for mounting the fan 20 to the fan mounting portion 13 will be described. FIG. 5 is a schematic side view showing a state when the fan 20 is attached to the fan attachment portion 13. As shown in FIG. 2, the end of the power cable 60 is disposed in the vicinity of the fan 20 in advance. For this reason, first, the connection terminal provided at the end of the power cable 60 is connected to the input terminal 24 of the fan 20. Next, as shown in FIG. 5, the cylindrical portion 231 of the fan 20 is inserted into the opening hole 12 from the front surface side of the clothing body 10. Then, the lower surface of the flange 22 of the fan 20 is bonded to the frame body 131 by the adhesive tape 132 provided on the frame plate 131. In this way, the fan 20 can be easily attached to the clothing body 10. In addition, the operation | work which attaches the fan 20 to the fan attachment part 13 is performed in the last process among the manufacturing processes of the air-conditioning protective clothing 1, for example.

The filter 30 is for removing a specific substance in the air, for example, a harmful substance. It is one of the features of the present invention that the air-conditioning protective clothing 1 of this embodiment includes this filter 30. Hereinafter, a case where a specific substance is a harmful substance will be described. In the present embodiment, a sheet-like filter 30 is used. As shown in FIG. 2, the peripheral end portion of the filter 30 is fixed to the back side of the clothing body 10 so that the filter 30 surrounds the two

fans

20, 20 from the back side of the clothing body 10. Here, when the peripheral end of the filter 30 is fixed to the back side of the clothing main body 10, the substantially central portion of the power cable 60 is also fixed between the filter 30 and the clothing main body 10 without a gap. Accordingly, a part of the power cable 60 is located outside the filter 30 and the other part of the power cable 60 is located between the filter 30 and the clothing body 10. Here, the power cable 60 between the filter 30 and the clothing main body 10 is branched into two as shown by a dotted line in FIG. A connection terminal for connecting to the input terminal 24 of the fan 20 is provided at each end portion of the branched power cable 60. Further, a connection terminal for connecting to an output terminal (not shown) of the power supply means 50 is provided at the tip of the power cable 60 outside the filter 30.

Further, an inner pocket 14 for storing the power supply means 50 is provided on the back side of the clothing body 10. The power supply means 50 is for supplying power to the two

fans

20 and 20. Here, a power supply unit incorporating a battery is used as the power supply means 50.

Next, the filter 30 used in the air-conditioning protective clothing 1 of this embodiment will be considered.
In ordinary air-conditioning clothing, a rechargeable battery is used as a power source. In view of the capacity of the battery, a propeller fan with low power consumption and low static pressure is used as a fan used for the air-conditioning suit. Therefore, when a propeller fan is used as the fan 30 in the air-conditioning protective clothing 1 of the present embodiment, if a filter having a large air resistance is used as the filter 30, the amount of air that can be taken in through the filter is reduced. End up. Therefore, as the filter 30, it is preferable to use a filter that does not have a large air resistance.

In recent years, non-woven fabrics made of plastic fibers whose surfaces are permanently charged positively and negatively are used for various applications as filters with low pressure loss and high collection efficiency. However, in such a filter, fine particles are electrostatically attracted to the surface of the plastic fiber. Therefore, if the wind speed when passing through the filter is high, the collection efficiency of the fine particles decreases. Moreover, if the surface area of the filter is small, the amount of air that can be taken in through the filter is greatly reduced due to the air resistance of the filter.

In order to fundamentally solve these two problems, that is, a problem related to a decrease in collection efficiency and a problem related to a decrease in the amount of air taken in, it is necessary to use a filter having a large effective surface area. If the effective surface area is very large, the air resistance by the filter becomes very small, and a large amount of air can be taken in through the filter without any trouble. When the same amount of air is taken in, the speed of air passing through the filter is inversely proportional to the surface area of the filter through which the air actually passes. For this reason, the larger the surface area of the filter, the lower the speed of air when passing through the filter, and the collection efficiency is improved. As a general method of increasing the surface area, a pleating method is known. However, if the pleating process is performed at a certain high density, the effective surface area becomes smaller. Therefore, in the pleating process, the effective surface area is reduced. Cannot be dramatically increased. Therefore, even if the sheet-like filter 30 is pleated and the filter 30 is directly attached to the air intake portion 21 of the fan 20, the above two problems cannot be solved. The function as cannot be fully demonstrated.

In the air-conditioning protective clothing 1 of the present embodiment, the filter 30 is not attached to the air intake portion 21 of the fan 20 but is attached to the back side of the clothing body 10 like a normal clothing lining. A fan having a very large surface area compared to the area of the air intake portion 21 of the fan 20 can be used. Specifically, in this embodiment, a filter 30 having a length of about 40 cm, a width of about 90 cm, and a surface area of about 3600 cm ² is used. The area of the air intake part of the fan used for a general air-conditioning garment is about 40 cm ^{2. In} this embodiment, since two such fans are used, the total area of the air intake part 21 is about 80 cm ² . Therefore, in the air-conditioning protective clothing 1 of the present embodiment, the filter 30 having a surface area about 45 times the area of the air intake portion 21 of the fan 20 is used. Thereby, while improving the collection efficiency of the filter 30, a large amount of air can be taken in between the clothing main body 10 and the body or underwear through the filter 30. In general, if a filter 30 having a surface area approximately 10 times larger than the area of the air intake portion 21 of the fan 20 is used, there is a problem related to a decrease in the collection efficiency and a decrease in the amount of air taken in. Can solve the problem.

The air discharge unit 40 is for discharging the air flowing in the space between the clothing body 10 and the body or underwear to the outside. The air discharge part 40 is provided at a predetermined portion of the clothing main body 10 excluding the vicinity of the opening hole 12. Specifically, as shown in FIG. 1, in the clothing main body 10, air corresponding to a part corresponding to the vicinity of the cuff part, a part corresponding to the vicinity of the hem part, a part corresponding to the clavicle, and a part corresponding to the back of the head A discharge unit 40 is provided. Specifically, the air discharge part 40 is a sheet-like thing which can discharge | emit air outside from the surface of the site | part of the clothing main body 10 in which it was provided. In particular, in the present embodiment, a fine mesh-like material having water repellency is used as the air discharge unit 40. For this reason, even if contaminated water falls on the air discharge part 40, it does not enter the inside of the clothes body 10. Further, when the

fans

20 and 20 are driven, air is vigorously discharged from the air discharge unit 40 to the outside, so that intrusion of contaminated water or air can be completely prevented.

The spacing means 70 has air permeability and is for maintaining a spacing between the filter 30 and the body or underwear. 6A is a schematic front view of the spacing means 70 in the air-conditioning protective clothing 1 of this embodiment, FIG. 6B is a schematic side view of the spacing means 70, and FIG. It is a figure which shows a mode when it mounts | wears with. FIG. 7 is a view for explaining the positional relationship between the spacing means 70 and the filter 30.

As shown in FIGS. 6 (a) and 6 (b), the spacing means 70 includes a horizontally long spacer 71 and mounting means 72 provided at both ends of the spacer 71. Here, the mounting means 72 includes

rubber belt portions

721 and 721 connected to both ends of the spacer 71, and

planar fasteners

722 and 722 provided at the tip portions of the

rubber belt portions

721 and 721. As the spacer 71, for example, as described in Japanese Patent No. 4067034, a spacer having a flexible structure and extremely low air resistance is used. As shown in FIGS. 6C and 7, the spacing means 70 is attached to the user's body so that the filter 30 and the spacer 71 face each other when the user wears the clothing main body 10. For example, the user can easily attach the spacing means 70 by winding the spacer 71 around the body and attaching the

planar fasteners

722 and 722 to each other.

Next, the role of the interval means 70 will be described. Naturally, the filter 30 receives force from the air taken in from the fan 20 and moves to the body or the side with the undergarment. If there is no spacing means 70, a part of the surface of the filter 30 sticks to the body or underwear, and it becomes difficult for air to permeate through the part of the attached filter 30, and the effective area of the filter 30 is extremely small. turn into. By using the spacing means 70, the filter 30 is prevented from coming into close contact with the body or underwear, and a certain distance is secured between the filter 30 and the body or underwear, and the air that has passed through the filter 30 is allowed to enter the spacer 71. Therefore, it is possible to prevent the effective area of the filter 30 from being reduced. In addition, since the force which the filter 30 receives from air is very small, the spacer 71 does not need to have pressure resistance. Therefore, it is not always necessary to use the spacer 30 described in the above-mentioned Japanese Patent No. 4067034. For example, an extremely low density three-dimensionally smaller number of threads than a general three-dimensional woven fabric. It is also possible to use a woven fabric.

Next, a procedure for wearing the air-conditioning protective clothing 1 of the present embodiment will be described.
First, the user connects the connection terminal provided at the tip of the power cable 60 outside the filter 30 fixed to the back side of the clothing body 10 to the output terminal of the power supply means 50. Then, the power supply means 50 is stored in the inner pocket 14 of the clothing body 10. Thus, the user prepares the clothing body 10 with the power supply means 50 attached in advance. Next, the user attaches the spacing means 70 to the body by winding the spacer 71 around the body and attaching the

planar fasteners

722 and 722 to each other. Thereafter, the user wears the clothing body 10 with the power supply means 50 attached from above the spacing means 70.

Next, operation | movement of the air-conditioning protective clothing 1 of this embodiment is demonstrated in detail.
When the user operates a switch (not shown) of the power supply means 50, power of the necessary strength is supplied from the power supply means 50 to the

fans

20 and 20. As a result, the two

fans

20 and 20 start operating, and external air is taken into the clothing body 10. The taken-in air passes through the filter 30, and at this time, harmful substances contained in the air are removed by the filter 30. Moreover, since the pressure in the clothing main body 10 becomes a positive pressure by taking in air from the

fans

20 and 20, an air flow passage is automatically formed between the clothing main body 10 and the body or underwear. The air from which harmful substances have been removed by the filter 30 flows in the air flow passage. Here, even if there are some gaps in the seam, fasteners, cuffs, etc. of the clothing body 10 due to the positive pressure in the clothing body 10, external air (hazardous substances) from the gaps. Does not enter the clothing body 10. Thus, the air-conditioning protective clothing 1 of this embodiment has excellent performance as protective clothing.

On the other hand, the air from which harmful substances have been removed by the filter 30 circulates in the air flow passage and is discharged to the outside from the air discharge portions 40 provided in each part of the clothing body 10. For this reason, the air which distribute | circulates the inside of an airflow path vaporizes the sweat which came out of the user's body, and can cool a body with the heat of vaporization when that vaporizes. Thus, the air-conditioning protective clothing 1 of the present embodiment has the same cooling effect as a normal air-conditioning clothing.

Next, a procedure for removing the air-conditioning protective clothing 1 of the present embodiment will be described.
The user first takes off the clothing body 10 and then removes the spacing means 70 to remove the air-conditioning protective clothing 1 of the present embodiment. Here, when removing the air-conditioning protective clothing 1, it is important to prevent the user from being contaminated by harmful substances attached to the surface of the air-conditioning protective clothing 1, as in the case of removing the normal protective clothing. Moreover, after taking off the air-conditioning protective clothing 1, each part must be properly processed. Since the space | interval means 70 and the power supply means 50 are protected by the clothing main body 10 and the filter 30, they are not contaminated. On the other hand, the fan 20 is contaminated because it takes in contaminated external air. Similarly, the power cable 60 is also contaminated. The contaminated fan 20 and power cable 60 are discarded as they are, or washed and reused in the same manner as a tool such as a scoop or pliers used in the contaminated area.

In the air-conditioning protective clothing of this embodiment, the filter is arranged so as to surround the fan from the back side of the clothing body, and the peripheral end portion of the filter is fixed to the back side of the clothing body, so that the air intake portion of the fan is used as a filter. Since a filter having a surface area larger than the area of the filter can be used, the collection efficiency of the filter is improved and a large amount of air can be taken in between the clothing body and the body or underwear through the filter. it can. In addition, by taking in air from the fan, the pressure inside the clothing body becomes positive, and an air flow passage is automatically formed between the clothing body and the body or underwear, and even the cuffs of the clothing body, etc. Even if there is a gap, external air contaminated from the gap does not enter the clothing body, and thus the protective performance can be improved. In addition, the air from which harmful substances have been removed by the filter is circulated in the air flow passage and discharged to the outside through a plurality of air discharge sections, so that the air flowing in the air flow passage vaporizes the sweat that has come out of the body. The body of the user can be cooled by the heat of vaporization when the sweat is vaporized.

In the air-conditioning protective garment of this embodiment, for example, by sewing a rubber string having appropriate elasticity into the portion of the clothing body corresponding to the waist that is slightly below the position of the fan, A gap generated between the portion and the waist may be reduced. In this case, since the amount of the external air taken in by the two fans can flow below the waist, the upper body of the user can be intensively cooled.

In addition, this invention is not limited to said embodiment, A various deformation | transformation is possible within the range of the summary.

In the above-described embodiment, the case where a clothing body formed in the shape of a continuous clothing is used has been described. Among the protective clothing, there is a separate type that wears a top garment and pants separately. In such protective clothing, only the upper garment may have the function of the air-conditioning protective clothing of the present invention.
