[Problems to be Solved by the Invention] However, this conventional device only has the function of cooling the body surface, and does not allow the sweat that evaporates from the body surface or the condensation that is generated when the sweat condenses when it comes into contact with the cooling tube. No consideration was given to water treatment. Currently, these moistures are absorbed by the underwear worn by workers, which results in insufficient absorption and a problem in that a comfortable cooling effect cannot be obtained.

[0004] In addition, there are air-conditioned clothing that obtains a cooling effect by blowing cold air cooled to a predetermined temperature onto the body surface, but these air-conditioned clothing cannot be prevented from expanding due to the internal pressure caused by the cold air. However, it restricts physical movement and is difficult to use in narrow spaces, so it has not been put to practical use due to its ease of use.

[0005] The present invention has been made in view of the above points, and its purpose is to absorb moisture such as sweat from the body surface and condensed water condensed in cooling pipes by taking measures to actively absorb such moisture. To effectively release water from the air-conditioning clothes to the outside of the air-conditioning clothes, and to block external heat intrusion from the surface of the air-conditioning clothes to obtain a comfortable cooling effect.

[0006]

[Means for Solving the Problems] In order to achieve the above object, in the invention of claim 1, an air passage is formed together with a cooling pipe inside the clothes, and moisture such as sweat is removed by the air flowing through the air passage. It was designed to be absorbed and transported out of the clothes.

Specifically, as shown in FIG. 1, the air-conditioned clothing of the present invention has a flexible cooling material that is stretched around the body (B) surface side of the clothing and through which cold water or low-temperature brine flows. Pipe (4), (4), ... and this cooling pipe (4), (4)
,..., a heat insulating material (3) that has hygroscopic properties, a moisture permeable material (6) disposed inside the cooling pipes (4), (4),..., and these heat insulating materials ( 3) and the moisture permeable material (6), the air passageway (11) through which air flows.

In the invention according to claim 2, a molded material (5) having moisture permeability is disposed between the heat insulating material (3) and the moisture permeable material (6), and the molded material (5) and the transparent material A ventilation passage (11) is formed between the moisture permeable material (6) and the moisture permeable molded material (5) is alternately bent outward and inward to form an uneven shape. The cooling pipes (4), (4), . . . are accommodated in the open groove portion (5a).

[0009]

[Operation] With the above structure, in the invention of claim 1, after the sweat on the surface of the body (B) passes through the moisture permeable material (6), a part of it is transferred to the surface of the cooling pipes (4), (4), ... The condensed water is transferred to the heat insulating material (3) together with the condensed water, where it is absorbed and retained. Further, a portion of the moisture absorbed by the heat insulating material (3) is evaporated by heat from outside the clothing. Since the air passage (11) is formed between the heat insulating material (3) and the moisture permeable material (6), while the moisture moves as described above, the moisture flows through the air passage (11). It evaporates and is absorbed by the air flowing through it,
This air is discharged out of the clothes. Therefore, even if sweat or condensed water is generated, it is quickly removed, and the surface of the body (B) is always kept in a substantially dry state. In addition, since the heat insulating material (3) blocks heat from entering from the outside, a heat insulating effect can be obtained for the inside than the heat insulating material (3). A comfortable cooling effect can be obtained by these synergistic effects. The sweat and water droplets mentioned above are small amounts over time, and even if the entire amount is absorbed by the insulation material (3), an insulating air layer still remains in the insulation material (3), and its insulation effect is not damaged.

[0010] In the invention according to claim 2, a concavo-convex molded material having moisture permeability is provided between the heat insulating material (3) and the moisture permeable material (6).

The cold air ducts (12), (14), and (45) are hollow ducts made of polyethylene, polyvinyl chloride, or the like, whose cross-sectional area does not change due to deformation due to external forces.

[0021] The above vest (Gm) is converted into CBR protective clothing (
When worn under the protective clothing (Gm), the water supply and drainage hoses (8), (9) and the connecting cold air duct (14) protruding from the vest (Gm) must be passed through the protective clothing (Gm) in an airtight and watertight manner. There is. For this reason, as shown in Figure 7, in the protective clothing (Go), the water supply and drainage hose (8)
, (9) and an opening (16) is formed in a portion corresponding to the cold air duct (14). In this opening (16), as shown in FIG.
A caulking material (17) with a width of m is pasted, the other material is wrapped around this caulking material (17), and the button (
18), (18), etc., the water supply and drainage hoses (8), (9) and the cold air duct (14) are drawn out from the protective clothing (Go) in an airtight and watertight manner.

In FIG. 7, (19) is the protective clothing (G
This duct (19) is connected to the inside of the protective suit (Go), and the cold air ducts (14) and (12) are attached to the back of the head of the vest (Gm).
), the air released into the protective clothing (Go) is discharged from the clothing through an exhaust duct (19). A check valve (20) is attached to the tip of the exhaust duct (19) to prevent air from flowing back into the protective clothing (Go) through the exhaust duct (19). The stop valve (20) has a function of opening when the pressure inside the protective suit (Go) exceeds a predetermined value to discharge air outside the suit.

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

When using the vest (Gm), first,
The worker puts on the vest (Gm) over the underwear (Gi), and then puts on the CBR protective clothing (Go) over the vest (Gm). Connect the water supply and drainage hoses (8), (9) of the vest (Gm) and the connecting cold air duct (14) to the opening (Go) of the protective clothing (Go).
16) and fill the opening (16) with caulking material (1
7) and the button (18), the water supply hose (8) is connected to the cold water outlet (36) of the cold water circulation device (21), and the drainage hose (9) is connected to the cold water inlet (36).
Hose (33), (38) of the length required for each
). In parallel with this, the cold air duct (14) is connected to the cold air supply device (41) via the duct (45).
). In this state, install the cold water circulation system (21
), and the fan (43) of the cold air supply device (41), cold water is generated in the cold water tank (30),
This cold water circulates within the cooling pipes (4), (4), . . . in the clothing body (1) of the vest (Gm). This cools the surface of the body (B) and provides a cooling effect.

On the other hand, the cold air supplied from the cold air supply device (41) flows through the cold air duct (1) inside the clothes of the vest (Gm).
2) enters the air passage (11) in the clothing body (1) and flows upward through this air passage (11). In addition, some of it passes through the breathable lining (6) and passes through the underwear (Gi).
) or towards the body (B) surface and flows upward through this part.

By the way, the sweat flowing down the surface of the worker's body (B) is absorbed by the underwear (Gi), and a part of it becomes water vapor, which is cooled by the low-temperature cooling pipes (4) and condenses on its surface. liquefy. The above cooling pipes (4), (4),...
Since a moisture permeable heat insulating material (3) is provided on the outside of the cooling pipes (4), water droplets of condensed water on the surfaces of the cooling pipes (4), (4), etc. are removed from the lining (6) or the molding material (5). ) through the insulation material (3
) is absorbed and retained. Further, some moisture such as sweat moves to the outside of the heat insulating material (3) due to capillary action, and evaporates on its surface due to heat from outside the vest (Gm), that is, the outside of the protective clothing (Go). When the cold air flows in a state where moisture exhibits this behavior, this cold air absorbs moisture from the surface of the molded material (5), underwear (Gi), or body (B), making the humidity higher than that at the time of introduction. It becomes a high atmosphere. This air passes through the neck of the vest (Gm) and
) is blown out and into the protective clothing (Go). In addition, some cold air has the same effect as the best (Gm
) is emitted from the cuffs. Best like this (Gm)
The air released into the protective clothing (Go) is exhausted to the outside of the protective clothing (Go) through the exhaust duct (19).

Therefore, in this embodiment, even if sweat or the like occurs on the surface of the worker's body (B), it is removed from the vest (Gm).
) is absorbed and removed quickly and reliably by the cold wind blowing through the body (B), and the surface of the body (B) is always kept in a substantially dry state. In addition, since the heat insulating material (3) blocks heat from entering from the outside, a heat insulating effect can be obtained for the inside than the heat insulating material (3). A comfortable cooling effect can be obtained by these synergistic effects.

[0028] Also, the heat insulating material (3
) and the lining (6), a moisture-permeable uneven molded material (5) is arranged, and the outer grooves (5a), (5a), ... formed in the molded material (5) are arranged between the molded material (5) and the lining (6). Cooling pipes (4), (
4) is accommodated, so each cooling pipe (4) is connected to the body (B).
) It can be brought close to the surface side, and the cooling efficiency for the body (B) surface can be increased. Moreover, the molding material (5
The inner groove (5b) (other than the outer groove (5a)) is away from the surface of the body (B), and the space between it and the lining (6) is the air passage (11). (11) Space can be effectively secured.

[0029] There is a concern that the moisture permeable heat insulating material (3) absorbs sweat and water droplets, reducing its heat insulating effect.
Sweat and water droplets are small amounts, even if the entire amount is absorbed by moisture-permeable insulation (3)
Even if it is absorbed by the moisture permeable heat insulating material (3), a heat insulating air layer still remains in the moisture permeable heat insulating material (3), so its heat insulating effect is not significantly impaired.

In the above embodiment, the cold air is supplied into the vest (Gm) at room temperature, but the temperature may be changed as necessary. In particular, when low-temperature air cooled to a low temperature by a refrigeration device is supplied, comfort can be further improved by increasing the cooling effect.

Further, in the above embodiment, a dedicated cold air supply device (41) is provided, but in addition to this, for example, in a vehicle manufactured for the purpose of CBR protection (such as a tank), a CBR protection device (41) is provided.
A clean air supply system that supplies clean air for crew breathing through a BR protection filter may be equipped, and the CBR protection may be used to supply clean air to the respiratory system only in non-emergency conditions. Instead, the cold air can be supplied to the vest (Gm) through a cold air duct, which eliminates the feeling of stuffiness for the crew compared to simply wearing CBR protective clothing (Go) directly over underwear (Gi). You can get a comfortable cooling effect.

The vest (Gm) is not limited to the vest type as in the above embodiment, but may also be of the type with sleeves. Furthermore, in the vest, the outer material (2) can be omitted if necessary. Furthermore, the present invention can of course be applied to types of clothing other than vests (Gm).

[0033] Also, as in the above embodiment, the cooling pipe (4),
(4) Instead of circulating cold water, brine as a heating medium may be used.

[0034]

As explained above, according to the invention according to claim 1, not only the cooling pipes but also the air passages are arranged in the air-conditioning suit, thereby removing sweat and condensed water on the surface of the cooling pipes.
It can be evaporated into the air flowing through the air passage and quickly released outside the cooling clothes, drying the body surface and obtaining a comfortable cooling effect, and the insulation effect of the insulation material on the surface of the clothes prevents heat from entering outside. This can reduce the cooling load.

According to the second aspect of the invention, the moisture permeable molded material disposed between the heat insulating material and the moisture permeable material in the air-conditioned clothing is made into an uneven shape, and cooling is provided in each concave groove portion open to the outside. By accommodating the tube, the cooling tube housed in the concave groove of the molded material is brought closer to the body, and the portion of the molded material without the cooling tube is separated from the body, creating an air passage between it and the moisture permeable material. By bringing the cooling pipe close to the body, it is possible to increase the cooling efficiency for the body surface and secure the space for the air passage.
