[Detailed Description of the Invention] (Industrial Application Field) This invention is applicable to workers who work in a hot environment, such as crane operators, workers at iron and steel manufacturing sites, workers in the glass and other ceramic industries, etc. This invention relates to air-conditioned clothing suitable for.

(Prior Art) Various types of air-conditioned clothing for use in this type of thermal environment have been known. For example, clothing that has cooling pipes stretched around the body surface side and circulates cold water or low-temperature brine through these cooling pipes to cool the body surface (for example, "CHANICAL ENGINEER").

153319), etc.

In addition, there is also air-conditioned clothing that achieves a cooling effect by blowing cold air at a predetermined temperature into a cold air passage inside the clothing through an inlet, circulating it, and discharging it through an outlet.

(Problem to be solved by the invention) By the way, the type of air-conditioned clothing that blows cold air into the clothing can be manufactured at low cost, is lighter than the structure with a built-in cooling tube as described above, and further reduces the intraocular temperature. It has the advantage of being able to do this properly.

However, on the other hand, the circulation of cold air throughout the body is poor, and furthermore, the temperature and humidity of the cold air rises due to heat generation and sweating from the body between the cold air inlet and the outlet, causing the area near the inlet to become too cold. On the other hand, the cooling effect is low near the vent, and there is a problem that the cooling effect on the body is uneven.

In addition, the flow rate of cold air is adjusted by the cold air vent, which prevents the clothes from expanding due to the increase in internal pressure in the cold air passage.As the clothes expand inward, the body is tightened and movement is restricted. When it expands outward, it becomes difficult to use in narrow spaces, which is disadvantageous in terms of maneuverability.

The present invention has been made in view of the above, and its purpose is to improve the structure of air-conditioned clothes having cold air passages as described above, thereby allowing cold air to flow toward the surface of the body. The objective is to improve the circulation of cold air, uniformly cool the entire body, and suppress the expansion of the clothes due to the increase in internal pressure in the cold air passages, thereby improving the usability of the cooling clothes.

(Means for Solving the Problem) In order to achieve the above object, in the invention of claim (1), the air-conditioned clothing has a double structure with an inner layer and an outer layer structural material connected to each other, and a A cold air passage is formed in the body, and the inner layer structural material is made of a material through which air can pass, so that the cold air from the cold air passage is blown out to the body surface side through the inner layer structural material.

Specifically, in the invention of claim (1), as shown in FIG. An inner layer structural material (3), which is arranged at a predetermined interval on the outside of this inner layer structural material (3) and is integrally connected to the inner layer structural material (3) via a connecting member (5), and is It is composed of an outer layer structural material (4) with low air permeability.

A cold air passage (6) through which cold air flows is formed between the inner layer structural material (3) and the outer layer structural material (4), and the cold air passage (6) is characterized by a cold air introduction port (9). In the invention of claim (21), as shown in FIG. 2, openings (12), (12), etc. are provided in the inner layer structural material (3) at locations where a large amount of cold air is required to be delivered to the body surface.

(Function) With the above configuration, in the invention according to claim (1), the outer layer structure material (4) of the air-conditioned clothing is made of a material with low water vapor and air permeability, while the inner layer structure material (3) is made of a material with low water vapor and air permeability. Since it is made of a sheet-like water-repellent porous material that allows water vapor and air to pass through, when cold air is introduced into the cold air passage (6) from the cold air inlet (9), this cold air permeates through the inner layer structural material (3). It is then blown out to the body surface side, and is then discharged to the outside of the bottle through a normal opening 1 of the cooling suit, such as an opening in the cuff or collar, through a space between the cooling suit and the body surface. At that time, the cold air passage (6)
The cold air introduced into the air conditioner circulates throughout the air-conditioned clothing and then blows out toward the body surface through the inner layer structure material (3). Therefore, the cold air circulates well and the cold air with the same temperature and humidity is supplied to all parts of the body, so that the surface of the body can be cooled uniformly.

Moreover, since the inner layer structure material (3) blows cold air toward the surface of the body, sweat generated on the body surface is absorbed by underwear or the like and then evaporated by the cold air.

Therefore, the surface of the body can be cooled while drying, and a comfortable cooling effect can be obtained.

Moreover, since the inner layer structure material (3) is made of a sheet-like water-repellent porous material, sweat generated on the body surface does not flow back into the cold air passage (6) on the outside, and inside the cold air passage (6). It can effectively prevent stains etc. from forming on the surface.

Furthermore, since the inner layer structural material (3) and the outer layer structural material (4) are connected by the connecting material (5), even if the internal pressure of the cold air passage (6) increases due to the introduction of cold air, the connecting material (5) ), and the inner layer structural material (3) is prevented from expanding more than necessary toward the body side, and the outer layer structural material (4) is also prevented from expanding more than necessary. As a result, the body is prevented from being constricted by the air-conditioning suit, making it more comfortable to wear, and allowing the wearer to move freely even in narrow spaces, thereby improving the usability of the air-conditioning suit.

In the invention of claim (2), the inner layer structure material (3) is provided with openings (
12), (12), ... are provided, so the cold air flowing from the cold air passage (6) to the body surface is directed to the opening (12).
, (12>P1...), the cooling effect increases more than other parts, and the cooling effect on specific parts of the body can be increased.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

Both structural members (3) and (4) are connected together by a connecting member (5) made of thread, narrow cloth tape, etc., and cold air flows between the structural members (3) and (4). Flowing cold air passage (6
) is formed.

Furthermore, a friction reducing material (8) is sewn onto the inner surface (body side) of the inner layer structural material (3) via a spacer (7). The friction reducing material (8) is made of a material such as nylon or rayon that slides smoothly against the underwear worn by the worker.

Furthermore, as shown in FIG. 3, a cold air inlet (9) communicating with the cold air passage (6) is located at the lower left side of the air-conditioned clothing (G).
) is opened, one end of a flexible air guide pipe (10) is connected to this inlet (9), and the other end of this air guide pipe (10) is connected to a cold air supply device (11). ing. This cold air supply device (11) discharges air cooled by a refrigerator (not shown) or air outside the thermal environment conditions where the worker is present, and the cold air discharged from the cold air supply device (11) is The air is supplied to the cold air passageway (6) of the air-conditioned clothing (G).

In addition, as shown in enlarged detail in Fig. 2, the inner layer structure material (
Among 3), pores (12), (12), etc. of a predetermined size are formed as openings in areas that require a large amount of cold air on the body surface, such as the armpits. Cold air passage (6) from holes (12), (12),...
The cold air is blown out towards the surface of the body.

Next, the operation of the above embodiment will be explained.

When using the air-conditioned clothing (G), the air-conditioned clothing (G) is worn over underwear and a jacket is placed over it. Thereafter, the cold air inlet (9) of the air-conditioned clothing (G) is connected to the cold air supply device (11) via the air guide pipe (10), and in this state, the cold air supply device (11) is connected to the cold air supply device (11).
) is activated, the cold air discharged from the cold air supply device (11) is supplied to the cold air passage (6) of the air-conditioned clothing (G).

The outer layer structural material (4) that makes up the outer wall of the cold air passage (6) is made of a material with low permeability to water vapor and air, while the inner layer structural material (3) that makes up the inner wall is made of a repellent material that allows water vapor and air to pass through. Since it is made of water-based porous material, the cold air passage (6)
) is blown out to the body surface side (underwear) through the inner layer structural material (3), spacer (7) and friction reducing material (8).

A space is formed between this body surface and the friction reducing material (8), and this space communicates with the normal opening 1 of the air-conditioned clothing (G), such as the opening of the cuffs or collar, so that the friction reducing material (8) is The cold air blown from the lightening material (8) passes through the opening and is discharged to the outside of the air conditioner clothing (G).

In that case, the cold air introduced into the cold air passage (6) first circulates through the cold air passage (6) of the entire air-conditioned clothing (G), and then is blown out to the body surface side through the inner layer structure material (3). Therefore, the cold air is distributed throughout the air-conditioned clothing (G) well, and the cold air with the same temperature and humidity is supplied to every part of the body, so that the surface of the body can be uniformly cooled.

In addition, since the cold air is blown out towards the surface of the body, sweat generated on the body surface is absorbed by the underwear and then evaporated by the cold air, cooling the body surface while drying it, creating a comfortable cooling effect. Can you get it?

Furthermore, since the inner layer structure material (3) is made of a water-repellent porous material, sweat generated on the body surface does not flow back into the cold air passage (6) of the outside ff1lJ, but instead flows into the cold air passage (6). It is possible to effectively prevent stains from occurring.

In addition, since the inner layer structural material (3) and the outer layer structural material (4) are connected by the connecting material (5), if the internal pressure of the cold air passage (6) increases due to the introduction of cold air, the connecting material (5) ), the inner layer structure material (3) is restricted from expanding more than necessary toward the body, and the outer layer structure material (4) is prevented from expanding more than necessary. As a result, the body is prevented from being tightened by the air-conditioned clothing (G), and comfort can be improved. Moreover, since the cooling suit (G) does not bulge outward, the worker can move freely even in a narrow space, thereby improving the usability of the cooling suit (G).

In addition, in the inner layer structure material (3), pores (12), (12
), ... are formed, so the cold air flowing from the cold air passage (6) toward the body surface side flows through the pores (12), (12), ...
・It will be more than other parts. Therefore, a specific part of the body that is particularly desired to be cooled can be effectively cooled by the cold air, and the cooling effect on that part can be increased.

Note that the air-conditioned clothing is not limited to the mid-front type as in the above embodiment, and may be, for example, a chonki type.

Furthermore, it is also possible to omit the spacer (7) and the friction reducing material (8) if necessary.

(Effects of the Invention) As explained above, according to the invention according to claim (1), the air-conditioned clothing is made of an outer layer structure material made of a material with low permeability for water vapor and air, and a sheet-shaped material that is permeable to water vapor and air. It has a double structure with an inner layer structural material made of a water-repellent porous material, and both horizontal members are connected by a connecting material, and a cold air passage is formed between the side structural members, so that the cold air from the cold air passage is transferred to the inner layer. By blowing out through the structural material to the body surface side, the body surface can be uniformly cooled while drying, and a comfortable cooling effect can be obtained. In addition, since the inner layer structure material is made of a sheet-like water-repellent porous material, the inner layer structure material made of the water-repellent porous material prevents sweat generated on the body surface from flowing back into the outside cold air passage. This effectively prevents dirt from forming inside the cold air passage. Furthermore, since the inner layer structural material and the outer layer structural material are connected by a connecting material, even if the internal pressure of the cold air passage increases due to the introduction of cold air,
It is possible to prevent each structural material from expanding more than necessary, and it is possible to prevent the body from being constricted by the air-conditioned clothing, increasing comfort. It also allows the air-conditioning clothing to be used in narrow spaces, improving its usability. .

According to the invention of claim (2), by forming an opening in a specific part of the inner surface structure material, the amount of cold air blown out from the cold air passage to the body surface is increased only by the opening, thereby providing a cooling effect on the specific part of the body. can be increased.
