Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temperature control garment for cooling a human body, which constitutes a part of a garment by a large number of cooling panels to which cooling water is supplied. The present invention relates to the structure of a cooling panel in such a temperature control garment.

[0002]

2. Description of the Related Art For example, an operator who works in a nuclear facility generally wears work clothes having a high sealing property for radiation protection, and is extremely hot and has a high sweating rate. Therefore, there has been proposed a temperature control garment that cools a human body by forming a part of the protective garment with a large number of cooling panels to which cooling water is supplied (for example, Japanese Patent Laid-Open No. 62-227353).
(See Japanese Patent Publication).

In the case of the temperature control garment of the known example, as shown in FIGS. 8 to 10, two soft vinyl chloride sheets 2 and 3 are fused and a cooling water passage 4 is formed therein. A large number of rectangular cooling panels 1 provided with partitions 11 form a part of clothes. In this case, the cooling water passage 4 in the cooling panel 1 has a plurality of branch passages 4a formed in parallel with the cooling water W supplied from the inlet 5 provided at one corner of the cooling panel 1. After being divided into 4a ..., they are assembled so that they flow out from the outlet 6 provided at the diagonal position of the inlet 5 in the cooling panel 1.

[0004]

However, in the case of the above-mentioned known example, when the cooling water W is supplied to the cooling panel 1, as shown in FIG.
As shown in FIG. 0, the inner and outer sheets 2 and 3 forming the cooling water passage 4 swell in both the inner and outer directions, so that the contact area with the human body M becomes small and the cooling efficiency deteriorates.

Further, the cooling water passage 4 has a parallel branch passage 4a,
4a ・ ・, therefore, the branch roads 4a, 4a ・
・ Drift may occur between them.

The present invention has been made in view of the above points, and an object thereof is to improve the cooling efficiency by increasing the contact area between the cooling panel and the human body.

[0007]

The basic structure of the present invention is as follows:
In a temperature control garment comprising a plurality of cooling panels to which cooling water is supplied, which constitutes a part of the garment, each of the cooling panels is an inner surface sheet that is in contact with a human body surface and does not deform even when the cooling water is supplied. It is characterized in that it is constituted by an outer sheet which is adhered to the outer surface of the inner sheet and forms a cooling water passage for supplying the cooling water between the inner sheet and the inner sheet.

In the basic configuration of the present invention, the cooling water passage is preferably a series of meandering passages from the inlet side to the outlet side, and the inlet and the outlet of the cooling water passage are
It is more preferable to provide the cooling water panel at the center of two opposite sides.

[0009]

In the basic configuration of the present invention, when the cooling water is supplied to the cooling water passage in the cooling panel, the inner sheet contacting the human body is not deformed and the outer sheet secures the cooling water passage. The contact area with will increase as much as possible. Therefore, the cooling efficiency with the cooling water is significantly improved.

Further, when the cooling water passage is a series of meandering passages from the inlet side to the outlet side, the cooling water can be supplied by a pump having a small flow rate and the cooling water flows from the inlet side to the outlet side. Since there is no branching / merging as in the conventional example, it is possible to prevent a decrease in cooling efficiency due to uneven flow.

Further, when the inlet and the outlet of the cooling water passage are provided in the central portions of the two sides of the cooling water panel which face each other, when the plurality of cooling panels are used as a part of the clothes, the cooling panels are mutually connected. The positional relationship of the connecting tubes is simplified.

[0012]

According to the basic configuration of the present invention, in a temperature control garment in which a plurality of cooling panels to which cooling water is supplied constitutes a part of the garment, each cooling panel is brought into contact with the human body surface. And configured by an inner surface sheet that does not deform even when supplying cooling water, and an outer surface sheet that is adhered to the outer surface of the inner surface sheet and forms a cooling water passage through which the cooling water is supplied between the inner surface sheet, When supplying cooling water, the inner sheet that comes into contact with the human body is not deformed, and the outer sheet secures the cooling water passages, which increases the contact area between the cooling panel and the human body as much as possible. There is an excellent effect that the cooling efficiency by water is significantly improved and it becomes comfortable for the operator.

When the cooling water passage is a series of meandering passages from the inlet side to the outlet side, the cooling water can be supplied by a pump having a small flow rate, and when the cooling water flows from the inlet side to the outlet side, Since there is no branching and merging as in the conventional example, it is possible to prevent a decrease in cooling efficiency due to uneven flow and to obtain an effect that it is more comfortable for the operator.

Further, when the inlet and the outlet of the cooling water passage are provided at the central portions of the two sides of the cooling water panel which face each other, when the cooling panels are used as a part of clothes, the cooling panels can be connected to each other. An effect that the configuration can be simplified can be obtained.
