Description

{Heating sleeping bag used without electricity}

The present invention relates to a heat-generating sleeping bag for use without electricity, and more particularly, to a heat-generating sleeping bag which can generate heat and heat by using only sunlight without using electricity. It is about techniques that can reduce the mortality rate of neonates and elderly people due to hypothermia in difficult areas.

After industrialization, the average temperature of the Earth has risen by 1.1 degrees Celsius before the industrialization. Rainfall in some parts of Africa has fallen by more than 60% from average to famine caused by famine. The dry climate continues to grow, with dry areas generally having large daily variability. In wet areas, water slowly warms and slowly cools, while dry areas do not have the energy to store, so the temperature drops sharply as the sun disappears at night. In the case of a desert, it often falls below zero at night, causing hypothermia.

Hypothermia refers to a state in which the central body temperature of the human body falls below 35 ° C. Moving air is even more dangerous when the wind is blowing with the cold because it is more effective than the stationary air. Sometimes it occurs when the house is not well heated and is in the house for a long time, especially in infants and elderly people. Generally, when the central body temperature falls below 35 ° C, heart, brain, lung or other important organ functions begin to deteriorate.

Generally, a heating element is necessary for the warming, and most of the heat is generated by electricity. However, underdeveloped countries such as Africa are facing severe power shortages due to poor infrastructure in power industry such as power generation and transmission. The existing infrastructure is aging due to lack of maintenance and maintenance due to constant anxiety such as civil war, and new investment is also lacking. The electricity penetration rate in Africa is well below the global average of 43%, and about 635 million people are not receiving electricity. In Sub-Saharan Africa, the electricity penetration rate is 32% lower than the African average and only 17% in the non-urban area.

Therefore, the present inventors have found that, if a heat-generating sleeping bag capable of generating heat and keeping warm can be manufactured by using only sunlight without using electricity, it is possible to provide a sleeping bag for a newborn baby due to hypothermia And the mortality rate of the elderly can be reduced. Thus, the present invention has been accomplished.

In the following, various aspects and various embodiments of the present invention will be described in more detail.

The following embodiments relate to a heat-generating sleeping bag capable of generating heat and keeping warm using only sunlight without using electricity. The heat-generating sleeping bag is a heat-generating sleeping bag that converts and stores the light energy of sunlight into thermal energy, Fiber, a heat storage for maintaining the temperature of the thermal energy, and an insulating fiber for minimizing the loss of heat to the outside, so that the heat energy stored in the daytime by the sunlight can be used without power supply, It is characterized by the prevention of body temperature reduction.

It is expected that the use of the heat-resistant sleeping bag according to the present invention can reduce the mortality rate of the newborn and the elderly due to hypothermia in a region such as Africa where the day-to-day variation is large and the electricity production is difficult.

Preferred embodiments of the heat-generating sleeping bag according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a longitudinal sectional view of a heat-generating sleeping bag according to an embodiment of the present invention, FIG. 2 is a plan view of a heat-generating sleeping bag according to an embodiment of the present invention, and FIG. 2 is a perspective view of a folded state.

As shown in Figs. 1 and 2, the present invention is characterized in that a lower mat (10) forming a floor and an upper mat (20) extending in a foldable manner on one side of the lower mat are opposed to each other, Wherein the lower mat comprises a first heat insulating fiber (11); And a heat storage fiber (14) located on the upper surface of the first heat insulating fiber, wherein the heat storage fiber comprises a heat storage body (12); And a first heat-generating fiber (13) located on an upper surface of the heat storage body, wherein the upper mat comprises a second heat-insulating fiber (21); And a second heat-generating fiber (22) located on the upper surface of the second heat-insulating fiber.

1, in a state in which the lower mat 10 and the upper mat 20 extending to one side of the lower mat are folded before being folded, the first heat-generating fiber 13 and the second heat- 22 are positioned on one side extending from each other. As described above, the first heat-generating fiber 13 and the second heat-generating fiber 22 are made of the same material as that of the first heat-generating fiber 13 and the second heat-generating fiber 22, The extended side may store sunlight irradiated during the day and convert the sunlight into heat energy to supply heat energy to the inside of the heat-generating sleeping bag during the night when sunlight disappears.

Referring to FIG. 2 (b), in which the upper mat 20 is folded on the upper surface of the lower mat 10 and the body is accommodated by the opening and closing means, the first heat generating fiber 13 and the second heat generating The fibers 22 are positioned on the inner surface of the heat-generating sleeping bag and come into contact with the human body. At this time, the human body can prevent the rapid decrease of the body temperature due to the heat energy re-radiated from the first heat-generating fiber 13 and the second heat-generating fiber 22.

The heat storage body 12 is in the form of a gel in which the superabsorbent resin absorbs water, and there is a habit of easily absorbing and trapping moisture in the presence of hydrophilic ions. Since it has a property of increasing the size by several hundred to several thousand times when absorbing moisture and maintaining the temperature after swelling by moisture, it has an effect of continuing the keeping function by the first heating fiber. When the heat storage body 12 is present in the upper mat 20, it is preferable that the heat storage body 12 is included only in the lower mat 10 because the user feels discomfort due to the weight of the heat storage body.

The first heat-insulating fiber 11 and the second heat-insulating fiber 21 are located on the outer surface of the heat-generating sleeping bag, so that the heat retaining time is increased. Particularly, heat can be re-radiated to the high temperature side without releasing heat from the high temperature side to the low temperature side by using the reflection type heat insulating fiber.

The first heat insulating fiber and the second heat insulating fiber may be the same or different from each other and each independently may be a carbon fiber, a silica fiber, a zirconia fiber, a cellulose fiber, a polyphenylene benzobisoxazole, an aramid fiber, a PPS fiber polybutylene terephthalate, polyphenylene sulfide, polybenzimidazole, wool, and polytetrafluoroethylene. However, the first and second heat insulating fibers may have a low thermal conductivity It is preferable to use carbon fibers.

The thermal storage material may be a polymer gel, and the polymer gel may be in a form packaged in a packaging pack, but is not limited thereto.

The first heat generating fiber and / or the second heat generating fiber may contain zirconia. When the zirconia is mixed and radiated into the fiber, it has a dual storage effect of absorbing sunlight to convert the light energy into heat energy (infrared ray) and shielding the radiation of far infrared rays generated in the human body. The far- To promote blood circulation.

Also, the zirconia may be contained in an amount of 8 to 12% by weight based on the first heat-generating fiber and / or the second heat-generating fiber. If the weight is less than the lower limit of the weight range, the keeping time of the heating is significantly reduced. If the weight range is over the upper limit, the zirconia is used more than necessary, resulting in an economical problem.

The thicknesses of the first heat-insulating fiber and the second heat-insulating fiber are the same or different from each other, and are independently 1 to 5 mm. The thicknesses of the first heat-generating fiber and the second heat- To 3 mm, and the thickness of the polymer gel may be from 3 to 8 mm.

Further, as shown in Fig. 2 (a), when the heat-activated sleeping bag in the unfolded state has a size of 100 to 140 cm in width and 60 to 100 cm in height, it may be suitable for accommodating a newborn baby.

In particular, in the case of the exothermic sleeping bag of the above-mentioned size, the polymer gel may be used in an amount of 200 to 400 g, preferably 250 to 350 g, more preferably 280 to 320 g.

Further, the opening / closing means may be one kind selected from a zipper or a valve, but is not limited thereto, and preferably a zipper can be used.

Hereinafter, production examples and embodiments according to the present invention will be described in detail with reference to the accompanying drawings.

Thereafter, the temperature of the polymer gel was heated to 50 DEG C, and then the temperature was measured every 5 minutes until the temperature was further reduced to 30 DEG C. [

Referring to FIG. 6, when the amount of the polymer gel was 100 g, it decreased to 30 ° C in 55 minutes, while in the case of 300 g and 500 g, it took 80 minutes to decrease to 30 ° C. 300 g and 500 g are similar to each other, it is considered that the polymer gel of 300 g is suitable for light weight and economical use.

FIG. 7 is a graph showing the temperature duration of a polymer gel (thermal storage material) and a polymer gel (thermal storage material) + heat insulating fiber according to the present invention.

In order to evaluate the idea of minimizing the heat storage capacity and heat loss of the polymer gel accommodated in the packing pack, the polymer gel wrapped with the carbon fiber and the polymer gel not covered with the heat insulating fiber were heated to 50 ° C, Lt; RTI ID = 0.0 > 20 C < / RTI >

Referring to FIG. 7, it can be seen that it took about 80 minutes to reduce the polymer gel to 30 ° C. when using the polymer gel, whereas it took 190 minutes when the polymer gel was wrapped with the heat insulating fiber. This suggests that the thermal persistence time of the heating sleeping bag can be extended by using the polymer gel and the heat insulating material.
