Advantages and features of the present invention and methods for achieving them will be apparent with reference to the embodiments described below in detail with the accompanying drawings. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. To fully disclose the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims. Like reference numerals refer to like elements throughout.

Hereinafter, the present invention will be described with reference to the drawings for explaining a cold / hot mat using a phase change material according to embodiments of the present invention.

1 is a perspective view showing a cold and warm mat using a phase change material according to a preferred embodiment of the present invention, Figure 2 is a cross-sectional view showing a cold and warm mat using a phase change material according to a preferred embodiment of the present invention.

1 and 2, the cold mat according to a preferred embodiment of the present invention includes a cover portion 100 and the PCM fabric 110.

The cover part 100 includes an upper cover 102 and a lower cover 104.

The lower cover 104 is connected to the upper cover 102.

At this time, the cover part 100 is made of polyurethane and PVC soft.

The reason why the cover part 100 is made of polyurethane and PVC soft is to prevent the PCM made of a liquid to be described later from being discharged to the outside of the cover part 100 and at the same time to have elasticity. This is because PVC flexible is a material that is not stretchable and liquid can not pass, whereas polyurethane is a material that is stretchable and a material that can pass liquid.

The cover part 100 includes an upper cover 102 and a lower cover 104.

At this time, the upper cover 102 and the lower cover 104 is connected to the high-frequency adhesive to prevent the contents entering inside leak. In this case, the high frequency adhesion is possible because polyurethane and PVC are used together. In other words, the polyurethane itself is not made of high frequency bonding, but when PVC is used together with the polyurethane, high frequency bonding becomes possible.

As described above, the cover part 100 is made of polyurethane and PVC soft, so that high frequency adhesion of the upper cover 102 and the lower cover 104 is possible, and the contents contained in the cover part 100 are While not leaking to the outside at the same time the cover portion 100 is provided with elasticity.

PCM fabric 110 is provided in the cover portion 100, made of a phase change material to absorb heat.

PCM (phase change materials) refers to a phase change material, and refers to latent heat, heat storage material, heat storage material, heat control material.

Phase change material is a substance that accumulates a large amount of heat energy or releases stored heat energy through a phase change process. That is, the phase change material is a material that accumulates or releases heat in accordance with a physical change in phase from solid to liquid or liquid to solid.

PCM fabric 110 is preferably made of a phase change material (PCM) penetrated into a sponge or nonwoven fabric.

In particular, the PCM fabric 100 is preferably made to absorb the PCM in a superabsorbent sponge or superabsorbent nonwoven fabric. This is to prevent the PCM fabric 110 from becoming hard when it is changed from liquid to solid, so that the PCM fabric 110 is stretched and cushioned by a sponge or nonwoven fabric even if the PCM is changed from liquid to solid.

That is, by fusing a superabsorbent sponge or superabsorbent nonwoven fabric and allowing the PCM to be dispersed and absorbed in the superabsorbent sponge or nonwoven fabric, the elasticity and cushioning action of the PCM fabric 110 continues even if the PCM is changed to a solid in the PCM fabric 110. To be maintained.

On the other hand, PCM fabric 110 is instantaneous cooling when the temperature is 28 ℃ to 30 ℃, this instant cooling is sufficiently made within 1 minute.

Therefore, when the PCM fabric 110 is lukewarm and changes from solid to liquid, the cold material is placed on the PCM fabric 110, put in a refrigerator, or air-conditioned to lower the temperature of the PCM fabric 110. The PCM phase changes from liquid to solid and is cooled instantly.

As such, the mat or cushion using the PCM fabric 110 according to the present invention can cool the PCM fabric 110 in a very short time by using a phase change process of the PCM included in the PCM fabric 110.

That is, unlike a cooling method using a refrigerator or a low temperature space for a long time, it is possible to cool the mat or cushion quickly and easily by using a phase change made in a very short time.

In addition, the inside of the cover part 100, in addition to the PCM fabric 110, the superabsorbent polymers, greserine, grillol, etc. may be further mixed to add the coolness and warmth of the cushion.

Figure 3 is an exploded perspective view showing a cold and hot mat using a phase change material according to a preferred embodiment of the present invention.

It is preferable that a heat insulating material is further provided on the cold mat using the phase change material.

The heat insulating material 120 is provided between the PCM fabric 110 and the lower cover 104. And, the heat insulator 120 allows the PCM fabric 110 to be discharged in one direction to cool the discharged by the phase change, the opposite side can further maximize the effect of cold, warm mat or cushion by preventing the discharge. .

The lower cover 104 is a microfiber pad 130 is coupled to the outside of the bottom.

The microfiber pad 130 may be made of a cut loose yarn rope to perform a rich cushion role such as down. Therefore, the user can fully feel comfortable, warm and comfortable when sitting or lying down.

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive. The scope of the present invention is defined by the appended claims rather than the foregoing detailed description, and all changes or modifications derived from the meaning and scope of the claims and the equivalents thereof are included in the scope of the present invention Should be interpreted.
