Description

Human-wearable cooling fluid passage element and cooling clothing including the element

The present invention relates to a technique for cooling a human body.

Conventionally, a technique for reducing the heat of a person wearing a cooling suit by forming a cooling passage in the cooling suit and flowing a fluid such as water through the cooling passage has been proposed.
For example, Patent Document 1 provides a liquid passage formed of a porous resin material that does not allow liquid to permeate clothes and allows water vapor to pass therethrough, and allows a hygroscopic cooling fluid solution to flow in the liquid passage. A temperature-controlled garment that adjusts the temperature of the human body and absorbs sweat is disclosed.
Patent Document 2 includes a fabric having a mesh structure and a cooling pipe for passing a cooling fluid, and the cooling pipe is alternately woven and fixed on the front and back of the fabric through the mesh opening of the fabric. A cooling garment is disclosed.

However, in the above-mentioned Patent Document 1, a lithium chloride aqueous solution is exemplified as the hygroscopic cooling fluid solution, which is not sufficient in terms of simple and inexpensive use by general users.
In addition, since a heating and dehydrating means such as a heater tank is required, the cost is higher and the structure is complicated and a malfunction or the like may occur compared to a configuration in which water as a cooling fluid is simply circulated. There is a problem that increases.
Moreover, in the said patent document 2, since the cross section of a cooling pipe is circular, there exists a subject that the area which touches a human body will decrease. Further, when the cooling pipe is bent, the cooling fluid does not flow, and the cooling pipes are alternately woven into the fabric, so that there is a problem that the contact area with the human body is further reduced and the cooling effect cannot be enhanced.
In addition, as a method of attaching the tubular cooling passage to the cooling garment, a method of sewing the cooling pipe to the garment with a margin so that it can move to some extent is also conceivable, but a convex cooling pipe having a diameter of about 5 mm to 10 mm is attached to the sewing machine. It was technically difficult to sew clothes on the machine. In addition, sewing the cooling pipe on the clothes manually by the operator without using a sewing machine has a problem that it takes work time and the manufacturing cost is remarkably increased.

An object of the present invention is to provide a cooling fluid passage element equipped with a human body and a cooling garment including the element, which solves the problems of the prior art.

The opening includes an opening of a porous material such as a sponge made of a fibrous material that does not absorb water. The direction of the opening may be the vertical direction 8 or the width direction 9.
With this configuration, when a human body-mounted cooling fluid passage element or a cooling garment is configured corresponding to the movement of the human body to be cooled, the surface area of the opening is configured in the above range, so that the cooling liquid can be It can suppress that a flow is interrupted | blocked.
Further, by setting the surface area so that the flow of the cooling fluid can be satisfactorily secured in accordance with the magnitude of the movement of the portion where the human body is bent, good cooling can be realized even if the force of the pump for pushing out the cooling fluid is small.

The present invention is characterized in that the surface area of the opening 10 constituting the three-dimensional structure 6 is set to 1 mm ² to 25 mm ² .
With this configuration, compared with the configuration of the surface area of the opening, the cooling fluid can be reliably prevented from being blocked even in any movement of various parts of the human body within a preferable range. Cooling can be realized.

As the shape of the opening of the mesh, a quadrangular shape, a honeycomb shape, a triangular shape, or an indefinite shape in which the shape where the fibrous objects intersect with each other can be adopted.
If it is this structure, since the mesh which has already crossed in the up-down direction and has the softness | flexibility can be employ | adopted for the three-dimensional structure which concerns on this invention, a human body-mounted cooling fluid channel | path element can be manufactured cheaply. .

In the present invention, at least one joining portion 11 as a dividing line is provided in the cooling passage 4, and the joining portion 11 joins the upper sheet material 2a and the lower sheet material 2b positioned on the upper side when viewed from the human body. Thus, a plurality of branch cooling passages 4a are formed in the cooling passage 4.
If it is this structure, a some branch cooling channel | path can be formed in a cooling channel | path by providing a junction part. If the cooling fluid is subjected to an extrusion pressure, the cooling passage is divided into a plurality of branch cooling passages so that the cooling passage swells too much, resulting in a decrease in circulation of the cooling fluid, or a human-mounted cooling fluid passage caused by excessive swelling. The uncomfortable feeling when the element is mounted can be reduced.

The present invention uses a synthetic resin as a material constituting the upper sheet material 2a and the lower sheet material 2b when the seal portion 5 or the joint portion 11 is formed, and the upper and lower sheet materials. The three-dimensional structure 6 is composed of a synthetic resin component 2a and 2b and a synthetic resin component that is easily heat-sealed (heat sealed).
The above-mentioned “the three-dimensional structure is composed of a synthetic resin component that is easily heat-welded with a synthetic resin” means that the three-dimensional structure itself is composed of a synthetic resin component that is easily heat-welded and is thermally welded to the surface of the three-dimensional structure. And a case where a synthetic resin component that is easy to be coated is coated.
If an example of the said structure is given, when vinyl chloride is employ | adopted as an upper sheet material and a lower sheet material, it will be preferable to use vinyl chloride for solid structures itself, such as a mesh, or the surface. It is obvious that the combination of the three-dimensional structure and the upper and lower sheet materials can be selected as a material that can be easily joined to other synthetic resin materials other than vinyl chloride.
With this configuration, in the combination of the three-dimensional structure and the upper and lower sheet materials, the positional displacement of the three-dimensional structure can be reliably suppressed by heat welding, and the human body-mounted cooling fluid passage element or There is an advantage that can provide cooling clothes.

It is formed in the branch-shaped part 14.
If it is this structure, circulation of a cooling fluid can be favorably performed in the wide plane which covers a human body.

[First Embodiment]
Hereinafter, a first embodiment of a human body-mounted cooling fluid passage element 1 according to the present invention will be described with reference to the drawings.
For convenience, the “human body-mounted cooling fluid passage element 1” is abbreviated as “human body-mounted cooling element 1” in this specification as appropriate. Here, as the “cooling fluid” of the “human body-mounted cooling fluid passage element”, various fluids having a refrigerant function can be adopted as necessary in addition to general water. Examples of such fluids include fluids other than water and mixtures of water and various liquid substances. However, in view of cost and simplicity, it can be said that a cooling fluid containing water as a main component is preferable.
As shown mainly in FIGS. 1 to 3 (a) and 3 (b), various sheet materials 2 such as a vinyl chloride resin sheet are adopted, and vinyl chloride is interposed between the pair of upper and lower sheet materials 2a and 2b. The coated mesh 3 is sandwiched in the vertical direction 8 when viewed from the human body surface, and the cooling passage 4 is formed so as to extend in the width direction 9 when viewed from the human body surface.
The mesh 3 is employed as an example of the three-dimensional structure 6, and the three-dimensional structure 6 is made of a flexible material and is fixed by a fixing portion 7 so as not to be displaced in the cooling passage 4. In the configuration shown in FIG. 1, an example in which the fixing portion 7 is configured by a point portion 17 that fixes the three-dimensional structure 6 is shown. In the configuration shown in FIG. 2, the fixing portion 7 linearly extends along the direction in which the fluid flows. It is composed of a joint 11. The three-dimensional structure 6 is made of a fiber material such as a synthetic resin fiber that can secure a necessary and sufficient water channel without abundant moisture.

As shown in FIG. 1B, the three-dimensional structure 6 is a structure manufactured by knitting a fiber material in an up and down direction 8 almost alternately.
As an example of the three-dimensional structure 6, a net material in which vertical and horizontal fiber materials are knitted so as to intersect at least in the vertical direction 8 can be exemplified. In this case, as shown in FIGS. 1 and 2, a fiber material twisted up and down and left and right can be used.
Even if the mesh is the same, the element 1 is bent in the configuration in which the vertical member 20 and the horizontal member 21 intersect in the vertical direction 8 with respect to the abutting plane (human body surface) as shown in FIGS. 3 (a) and 3 (b). Even in the portion, the width D1 through which the cooling fluid flows is larger than the width in the vertical direction of the mesh 3, and a gap region through which the cooling fluid flows can be secured. The flow of this cooling fluid is indicated by an arrow 35 in FIG.
On the other hand, in the configuration of the mesh 47 in which the vertical members 20 and the horizontal members 21 are arranged on the same plane as shown in FIGS. 3C and 3D, when the cooling passage 4 is bent, the vertical members 20 and The thickness D2 in the vertical direction of the material 21 is smaller than the above D1, and it is difficult to secure a gap region for flowing the cooling fluid in the bent portion.
This is because when the cooling passage 4 is bent, the upper and lower sheet materials 2 a and 2 b are in close contact with the vertical surface of the mesh 47, so that the vertical thickness of the cooling passage 4 is the vertical direction of the mesh 47. This is because the gap area for flowing the cooling fluid cannot be secured in the vertical direction.

3 (a) and 3 (b), for simplicity, the three-dimensional structure 6 in which the vertical member 20 and the horizontal member 21 are formed as one layer is shown, but two layers, three layers,..., N Even when the three-dimensional structure 6 in which the vertical members 20 and the horizontal members 21 overlap each other like a layer is adopted, it is easily understood that a sufficient cross-sectional area through which the cooling fluid can flow can be secured even in the bent portion. it can.
That is, the most important thing is that the fibrous material of the vertical member 20 and the horizontal member 21 is not a single layer or an N layer, but a three-dimensional structure 6 having a gap region that can secure a sufficient amount of water when it is bent. It is a technical idea of whether or not.
Further, by setting the surface area of the opening 10 in the width direction 9 constituting the three-dimensional structure 6 such as the mesh 3 as well as the vertical direction 8 in the above-described ranges, the fibrous material positioned vertically also in the bent portion. As a result, it is possible to obtain an effect of reliably ensuring the flow of the cooling fluid.

In this embodiment, the method of securing the cooling passage 4 in the upper and lower sheet materials 2a and 2b made of a synthetic resin sheet or the like is a seal portion that seals around the cooling passage 4 so that fluid does not leak. 5 is provided. The seal portion 5 has a lateral width X (see FIG. 1A) that can be sewn or welded to the material of the cooling clothing. Although not shown in the drawings, the outer edge attaching portion 13 for attaching the human-body-mounted cooling element 1 to the cooling clothing 12 (see FIG. 5) may be separately provided on the outer edge of the seal portion 5 as described above. In FIGS. 1 and 2, the outer edge mounting portion 13 also serves as the seal portion 5.
As shown in FIGS. 1 and 2, the human-body-mounted cooling element 1 includes an inlet portion 18 into which a cooling fluid flows and an outlet portion 19 from which the cooling fluid flows out. A male-type and female-type connection portion may be provided in each of the inlet portion 18 and the outlet portion 19.
In addition, the length Y (see FIG. 1) where the inlet portion 18 and the outlet portion 19 are arranged is a considerably large length such as the vertical length of the cooling garment 12, for example, the length of the upper body or the height of the body. It can also be set.
FIG. 1 shows a configuration in which a plurality of linear seal portions 36 that divide the cooling passage 4 in the lateral width direction are provided near the inlet portion 18 and the outlet portion 19.

[Second Embodiment]
FIG. 2 is a view for explaining a second embodiment of the human-body-mounted cooling element 1 according to the present invention.
In the configuration of the second embodiment, the cooling fluid is formed in the cooling passage 4 by forming at least one joint portion 11 extending linearly (including a curved shape) along the direction in which the cooling fluid flows in the cooling passage 4. A plurality of branch cooling passages 4a are formed.
In general, the branch cooling passage 4a is formed by forming a partition line that is thermally welded together with the three-dimensional structure 6 with the upper sheet material 2a and the lower sheet material 2b interposed therebetween as viewed from the human body. That is, the joint 11 constituted by a dividing line is not only formed by a straight line and a curve dividing the branch cooling passage 4a, but also forms a cross line and a three-way to form a cooling passage 4 having a preferable shape. It may be composed of a combination of various lines such as lines.
If it demonstrates in a manufacturing process, as shown in FIG.6 (b) from the state arrange | positioned in order of the upper sheet material 2a, the three-dimensional structure 6, and the lower sheet material 2b from the upper side as shown to Fig.6 (a). At least one joint portion 11 that blocks the movement of the cooling fluid in the width direction 9 is provided at intervals of the length Z in the width direction with respect to the human body. As a method of joining, the method of welding the synthetic resin component between the upper and lower sheet materials 2a and 2b and the three-dimensional structure 6 by heat can form the branch cooling passage 4a most simply and inexpensively.

By adopting this configuration, for example, as shown in FIG. 6C, by providing four joints 11 with respect to the length L in the width direction of the cooling passage 4, The bulge diameter of the branch cooling passage 4a can be limited to the range of the above-mentioned diameter Z, and the bulge diameter of the branch cooling passage 4a can be set to Z with respect to the expansion of the original cooling passage 4 (original circle 22). Can be reduced in size. In other words, it can be said that the degree of adhesion of the branch cooling passage 4a on the surface in contact with the human body can be adjusted by appropriately increasing or decreasing the distance Z of the joint by adjusting the distance.
Further, when this concept is adopted, it is possible to improve the uniformity of the circulation of the cooling fluid when the entire cooling garment 12 is considered, and the cooling fluid locally exchanges heat with the body temperature of the human body, thereby cooling the cooling garment. It is possible to suppress the occurrence of inconvenience that the temperature of only a part of the region 12 is low and the region of the other cooling clothing remains high.

For example, the curvature of the head and the curvature near the spine are very different in the human body. Therefore, by adjusting the degree of swelling of the branch cooling passage 4a according to the shape of each cooling passage 4 (setting the value of the distance Z), it is possible to set a pressure-bonding degree and a cooling state that are preferable for the wearer. In other words, by changing the configuration of the lane markings of the joint 11 so as to be preferable in each part of the human body, optimal cooling is performed in each part (for example, head, top, back) of the worker wearing the cooling clothes. The degree and the pressure contact state can be set in advance.

[Third Embodiment]
Hereinafter, a device for applying the human-body-mounted cooling element 1 according to the present embodiment to the cooling garment 12 will be described as a third embodiment.

Moreover, as shown in FIG. 4, the joint part 26 is provided in the predetermined location of the trunk | drum element 1a. Connected to the joint part 26 is a cooling fluid circulation device including a battery and a pump (not shown). As a means for lowering the temperature of the cooling fluid, a configuration including a heat exchanging section that can lower the temperature of the cooling fluid so as to cool the temperature of the human body can also be adopted.
As a simple configuration of the heat exchange unit, there is a configuration in which a frozen cooling fluid such as ice is previously placed in a water container.
In addition, a heat exchange system capable of cooling the cooling fluid in the same manner as the cooling principle of the refrigerator can be adopted in a form in which a constant amount of power can be secured continuously, such as a motorcycle.
That is, the configuration of the human-body-mounted cooling element in the present embodiment can be adopted without depending on the configuration of the cooling fluid circulation driving device.
By placing a cooling fluid circulation device having a heat exchange part in a bag such as a ricksack and carrying it on the back, or attaching it to the waist or the like, the cooling water can be flowed to the cooling clothes worn by a freely moving worker.

In the branch-shaped portion 14, there are an intrusion channel 15 through which the cooling fluid flows to the distal end side of the branch-shaped portion 14 and a return channel 16 for returning from the distal end side of the branch-shaped portion 14 to the proximal end side. There is a point formed in each branch portion 14. The intrusion channel 15 and the return channel 16 are each composed of a human-body-mounted cooling element 1 as shown in FIGS.
Although not shown in FIG. 7, a plurality of branch cooling passages 4 a are usually provided in the intrusion channel 15 and the return channel 16.
