[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an insulated pillow maintained at a temperature close to room temperature.

[0002]

2. Description of the Related Art Pillows as bedding include grass pillows, wooden pillows, stone pillows, pottery pillows, and the like. Pillows and flat pillows are often used. The headland is usually a cotton woven cloth, and the filling in it is cotton, buckwheat hull,
Red beans, tea husks, rice husks, etc. are used.

[0003] As a secret of health and longevity, there is a word "head cold foot fever", and since pillows are the most familiar to implement, various attempts have been made for pillows. A water pillow is a typical example. Further, there are a pillow body formed as a bundle of tubes through which air can escape, and a pillow body having a board body in which a number of ceramic flat plates are connected vertically and horizontally.

[0004]

[Problem to be solved by the invention] In the case of a water pillow,
Because of the use of ice packed inside, the cooling effect of the head is very strong at first, and it is not suitable for health care because it is irritating, even if it is harmful to the health and there is body heat. Moreover, since water has little heat radiation, when the ice melts, it gradually approaches the body temperature, and eventually the cooling effect is lost, so it is necessary to refill the ice frequently.

[0005] In the case of the tube bundle structure or the ceramic disk body interior structure, some heat exchange is performed by the flow of air and the heat transfer function. However, high cooling performance cannot be obtained, and the head is hit hard. Can not be used comfortably.

[0006] In view of the above situation,
It is an object of the present invention to provide a cool pillow that is easy to use, is maintained at a temperature close to room temperature even when used continuously over time, and has a moderately supported head.

[0007]

In order to achieve the above-mentioned object, the present invention provides a heat transfer method in which fine particles of hard carbon or graphitic carbon having good thermal conductivity are mixed with water in a flexible bag. The fluid was filled and sealed to form a cool pillow.

[0008] In the above configuration, a surfactant is used to prevent heat spoilage in order to improve the thermal conductivity.
It may contain sodium chloride and trace amounts of germicides and preservatives.

[0009]

The hard carbon in a broad sense includes graphite-based carbon (fixed carbon) and hard carbon, and both are known to exhibit extremely high thermal conductivity. This is attributed to the presence of free electrons, and the thermal conductivity is higher than that of metal. Incidentally, heat is generally transported in a solid by carriers (electrons or holes) participating in electric conduction and propagation of lattice vibration. The thermal conductivity of hard carbon or graphitic carbon depends on the propagation of lattice vibration that facilitates carrier movement.

When such hard carbon or graphitic carbon fine particles having high thermal conductivity are mixed with water, they become a water slurry liquid (gel-like) and maintain high thermal conductivity. According to the configured cool pillow, when left at normal temperature or immersed in water, the temperature reaches that temperature in a short time.

When a cold pillow at room temperature is used as it is, the room temperature is lower than the body temperature (36 ° C.) and the room temperature is usually 25 ° C. even at a high temperature. Gently and rapidly cooled at temperatures close to Even if the temperature rises due to heat absorption, the heat is efficiently radiated to air and contact objects due to the high thermal conductivity. Therefore, even if it is used for a long time, the head is kept cooling.

Hard carbon or graphitic carbon is also a generator of far-infrared rays at room temperature. Far-infrared rays generated at room temperature have a wavelength of about 5 to 15 μm, and far-infrared rays having a wavelength in this range cause resonance / resonance in the body,
It has the effect of making blood work weakly alkaline.

[0013]

Next, an embodiment of the present invention will be described with reference to the drawings.

FIGS. 1 and 2 show one embodiment of the present invention. The cooling pillow is formed by filling a bag-like body 1 with a heat transfer fluid 3 having good heat conductivity and sealing it. You.

As the bag-like body 1, a composite film is used in which a nylon film 5 having a good touch on the outside and a durable polyester film 7 laminated on the inside thereof are used. The periphery is heat-welded in a state where the heat transfer fluid 3 is filled, and the flange-like edge 9 is heat-sealed around the periphery. In this case, vacuum degassing packaging is performed in order to prevent separation from the heat transfer fluid 3 and its decay, and to increase thermal conductivity.

The components of the heat transfer fluid 3 used were as follows. These are kneaded with a kneader or a mixer. Fixed carbon powder 50kg Water 35kg Glycerin 2kg Sodium chloride 15kg Sodium hypochlorite 250cc Sodium dehydroacetate 250cc

The fixed carbon fine particles have a purity of 99.4%, and the particle diameter is scattered at about 1000 μm to 1 μm, and is about 500 μm to 100 μm on average. When this is mixed with water, fluidity is obtained. The fixed carbon is obtained, for example, by forming coke or pitch and raising the temperature to about 3000 ° C.

Glycerin is used as a surfactant. Thereby, affinity between the components and between the components and the fabric of the bag-like body 1 can be obtained, and phenomena such as generation of cavities which may hinder thermal conductivity can be prevented. As other surfactants,
In particular, higher fatty acid-based nonionic surfactants which are excellent in emulsifying power, dispersing power, lubricating power and the like and are also hygienic are desirable.

Sodium chloride functions as a sterilizer and a bactericide. In addition, sodium hypochlorite is used as a bactericide, and sodium dehydroacetate is used as a preservative. Salt is known to improve health (eg, treat diabetes) by touching it in close proximity, even without direct contact with it, so its effect is expected.

After use, the cool pillow was left at room temperature of 22 ° C. for 1 hour, and the cool pillow having the same temperature was used again. did it. The temperature of the cool pillow after 5 hours of continuous use was 29 ° C (room temperature 20 ° C). When immersed in water (10 ° C.), the temperature was lowered to 12 ° C., which was close to the temperature, in about 3 minutes.

From the results of various experiments, the desirable ratio (% by weight) of each component is as follows. Hard carbon powder 35-60 Water 20-50 Surfactant 2-5 Salt 10-30 Disinfectant, preservative Trace amount

If the hard carbon powder is lower than the above range, the desired thermal conductivity cannot be obtained, and if it is high, the desired fluidity cannot be obtained. For water, the opposite is likely to happen.

FIG. 3 shows another embodiment. In this case, the insulated pillow of the above embodiment is used as the main body 2 and the pillow is put on the base 4 by bonding the flange-shaped edge 9. It is what I wore. The base 4 has a flat cylindrical shape with both ends removed, and has a large number of holes 10 on the upper surface.

When the cool pillow has such a structure, air flows through the table 4 and the contact area with the air increases, so that the efficiency of heat exchange with the air is improved. The table 4 is made of elastic rubber or synthetic rubber that is easily deformed so that air circulation is promoted by turning over. In addition, if the hard carbon powder is mixed in the material, the heat exchange efficiency is further improved.

[0025]

As described above, according to the present invention, the following excellent effects can be obtained.

1) Since a highly heat-conductive fluid made of hard carbon or graphitic carbon is filled,
By leaving it at room temperature, it quickly reaches a temperature close to it, the head is cooled gently, and even if it is used for a long time, the head is always kept at a temperature close to room temperature, so use is very simple . Also, no energy is required for cooling.

2) In addition to gentle cooling of the head, the head may be in soft contact, so it is very comfortable to use and not only as a sleeping pillow for inducing a good night's sleep, but also during sports and after work. It is the perfect pillow to relieve muscle fatigue. In addition, when cooled in water or a refrigerator, it is rapidly cooled, and thus can respond immediately to unexpected or unnecessary situations such as fever, headache, toothache, hangover, eyestrain, bruising, sprains and the like.

3) In addition, the effect of far-infrared rays by hard carbon or graphitic carbon is expected, and not only the promotion of sleep, but also the disease such as shoulder stiffness and headache due to resonance and resonance phenomenon with the wavelength. Improvement and health promotion are achieved.
