3 is a cross-sectional view showing the detailed structure of the cooling clothing of the present invention.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In describing the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the gist of the present invention, the detailed description will be omitted. In addition, terms to be described later are terms defined in consideration of functions in the present invention, which may vary according to the intention of a user or operator or a precedent. Therefore, the definition should be made based on the contents throughout this specification.

1 is a conceptual diagram showing a heat transfer path of cooling clothing in which comfort is improved by using vaporization heat according to the present invention, and FIG. 2 is a conceptual diagram showing a movement path of water and vaporized vapor in cooling clothing of the present invention. 3 is a cross-sectional view showing the detailed structure of the cooling clothing of the present invention.

1 to 3, the cooling clothing 100, which improves comfort by using heat of vaporization according to the present invention, largely includes an inner skin 101, a lower moisture-permeable waterproof layer 102 laminated on the inner skin 101, and , The absorbent sheet 104 disposed on the lower moisture permeable waterproof layer 102, the upper moisture permeable waterproof layer 106 disposed on the absorbent sheet 104, and the outer shell laminated on the upper moisture permeable waterproof layer 106 ( 107).

In addition, the cooling clothing 100 according to the present invention adopts a method of absorbing and cooling heat by vaporization or evaporation of water, as shown in FIGS. 1 and 2, and discharges to the outside through a moisture-permeable waterproof layer made of functional textile materials. Cooling function is demonstrated by utilizing the heat of vaporization of vaporized water.

Water is accommodated in the lower space 103 provided between the lower moisture-permeable waterproof layer 102 and the absorbent sheet 104 and the upper space 105 provided between the absorbent sheet 104 and the upper moisture-permeable waterproof layer 106. It is characterized by providing a cooling effect while absorbing ambient heat while the received water is vaporized.

In addition, although not shown, an inlet for injecting water may be installed in the cooling clothing of the present invention, and a stopper is installed at the inlet so as not to count water, and the user can selectively inject water into the cooling clothing if necessary. .

The inner shell 101 may be made of fabric, and the outer shell may be made of knitted fabric, but is not limited thereto.

The absorbent sheet 104 may be made of non-woven fabric, and is disposed between the lower moisture permeable waterproof layer 102 and the upper moisture permeable waterproof layer 106.

The absorbent sheet 104 divides the lower space 103 and the upper space 105, but since it is made of a material capable of absorbing water, water in each space can pass through each space.

The lower moisture-permeable waterproofing layer 102 does not pass the water accommodated in the lower space 103 toward the endothelium 101, and serves to pass water or steam vaporized from the endothelial 101 toward the lower space 103. do.

In spite of wearing the cooling clothing of the present invention, when the user's body sweats, the sweat is discharged through the lower moisture-permeable waterproof layer 102 as shown in FIG. Sweat absorbed into the space portion 103 is vaporized again, lowering the temperature of the water.

Similarly, the upper moisture-permeable waterproofing layer 106 passes water vaporized in the upper space 105 toward the shell 107, and external water passes through the upper space by the waterproof effect of the upper moisture-permeable waterproofing layer 106 ( 105) does not pass through.

The lower moisture-permeable waterproof layer 102 and the upper moisture-permeable waterproof layer 106 may be a material having selective permeability such as Gore-Tex that can transmit vaporized vapor but does not transmit liquid water. Since the waterproof and breathable structure of Gore-Tex is already known, a detailed description thereof will be omitted.

As described above, in the cooling clothing according to the present invention, as sweat is discharged and water is evaporated repeatedly, the water accommodated in each space is cooled by the vaporization heat, and the user can feel comfortable due to the low humidity, and the cooled water and When you touch it, you can feel the coldness.

Meanwhile, in the present invention, an antibacterial agent capable of providing antibacterial performance to the lower space or the upper space may be further included.

When water is accommodated in each space for a long period of time, an environment in which various microorganisms, molds, etc. can live is created, so it is preferable to prevent harmful bacteria, molds, etc. from propagating through antibacterial agents in advance.

Such an antibacterial agent may be an antibacterial powder coated with silver nanoparticles on the surface of at least one of zeolite and activated carbon powder, or a microcapsule containing an antibacterial component therein.

For example, in the case of antibacterial powder, it can be fixedly attached to the inner surface of the space by using a binder.

In the case of microcapsules, if necessary, they can be put together when water is injected, and when compressed or the wall material of the microcapsules melts, the antibacterial components inside are discharged to exhibit antibacterial performance.

As the wall material is known, natural and synthetic polymers such as starch, gum arabic, and cellulose may be mainly used, and the antibacterial component may be a natural component such as ginkgo extract or a commercially available synthetic component.

The present invention described above is only exemplary, and those skilled in the art will appreciate that various modifications and equivalent other embodiments are possible therefrom. Therefore, it will be well understood that the present invention is not limited to the forms mentioned in the detailed description above. Therefore, the true technical protection scope of the present invention should be determined by the technical spirit of the appended claims. It is also to be understood that the present invention includes all modifications, equivalents and alternatives within the spirit and scope of the present invention as defined by the appended claims.
