る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cold/thermal insulating material used for bedding, clothing, etc., in which a heat absorbing/radiating material that absorbs external heat and releases its own retained heat is placed in a suitable liquid-tight container. It is characterized by being filled in a bag or the like.

さが損なわれていた。 In general, stuffing for bedding and clothing is made by taking measures to increase its air retention.
The insulation ability of the fibers that make up these materials has been improved to ensure heat retention. However, even with the above-mentioned padded bedding and clothing, the temperature of these bedding items changes as the surrounding temperature changes, so some people may not use heating equipment during the winter. In many cases, it is necessary to warm the body using heat, and in the summer, the heat radiated from the human body causes the temperature to rise above the surrounding temperature, causing sweating and reducing comfort.

にしたことを特徴とする。 Therefore, the present invention is designed to reduce the temperature around the body when it is higher than the optimal temperature that the body feels, and to raise the temperature when the temperature around the body is lower than the optimal temperature that the body feels. In order to maintain the appropriate temperature, we used a heat-absorbing and dissipating material that absorbs external heat and releases its own heat, and in particular causes temperature changes within the range of body temperature and the temperature of the outside air.

から外れることがあつた。 Conventionally, heating materials that utilize the heat released when a heated heat medium such as a hot water bottle is cooled, and cooling materials that use heat that is cooled to a low temperature and removes heat from the surroundings, are known. They can only be heated or cooled by one heat medium,
Moreover, the temperature sometimes deviates from the comfortable temperature range desired by the human body.
本発明は斯る従来の保温保冷材の欠点をなく
し、１つの熱媒体によつて特に体温と外気の温度

せることを目的としている。 The present invention aims to eliminate the drawbacks of the conventional heat-insulating and cold-insulating materials, and to cause a temperature change in the human body during use, particularly within the range of body temperature and outside air temperature, by means of a single heating medium.
以下本発明の実施例を図面と共に説明する。 Embodiments of the present invention will be described below with reference to the drawings.

用する。 In the drawing, 1 is a stuffing made of cotton cotton or other suitable fibers, 2 is a side cloth that covers the stuffing 1, and a flat liquid-tight bag 4 is placed inside the stuffing 1 to hold a heat absorbing and dissipating material 3.
Fill and store. The heat absorbing and dissipating material 4 is made of an aqueous solution of salts that absorbs or radiates heat by changing its phase at around 27 to 30° C., at which the human body in contact with the material feels comfortable.

の保温能力を回復する。 An example of an aqueous solution of salts is a 50% aqueous solution (weight concentration) of calcium chloride, and as is clear from the solubility curve shown in Figure 2, this aqueous solution dissolves into CaCl 2 6H 2 at about 28°C. O is precipitated
Heat is released while solidifying, and the solidified aqueous solution has the property of melting CaCl 2 . If you store it,
Even if the outside air drops below 28°C, it can be kept at 28°C for a long time while precipitating and solidifying CaCl 2 6H 2 O in an aqueous solution. Furthermore, if the temperature of the solidified CaCl 2 6H 2 O is raised to 28°C or higher, it will absorb heat and melt, restoring its heat retention ability.

となり、多量の熱を放出する。 By the way, the heat retained by a calcium chloride aqueous solution is shown as follows: The solidification (melting) heat ΔHo is ΔHo=103.3Kcal /Kg・CaCl 2・6H 2 O The retained heat when an aqueous solution with a concentration of Co decreases to a concentration of Cf is QoKcal/Kg aqueous solution is Qo=Co−C/K−CΔHo K=CaCl 2 /CaCl 2・6H 2 O=0.5068, so when Co is 0.5 (30℃) → 0.48 (28℃), Qo is
It becomes an 80Kcal/Kg aqueous solution and releases a large amount of heat.

に持続される。 Figure 3 is a graph showing the heat dissipation (solidification) of the cold/thermal insulating material of the present invention.
When filled with a 52% calcium chloride aqueous solution, for example, one with an initial temperature of 37°C remains stable at 28°C for more than 15 hours after being left to stand, and reaches room temperature after about 30 hours. Therefore, if the cold/thermal insulating material of the present invention is used in the form of a hot water bottle, a hot water bottle, or a hot water bottle, the heat-retaining effect can easily be maintained throughout the day and night.

る。 On the other hand, if the outside air is above 28°C, such as in the summer, if this aqueous solution is appropriately solidified in advance, it will absorb external heat during use, and will melt due to body temperature during sleep, for example, and the bedding will be used during that time. It will be kept at 28℃.

放熱材４を取捨選択して用いることができる。 Note that calcium chloride becomes thinner when it absorbs moisture from the air, so it is filled into a bag 4 to prevent it from coming into contact with the air and used repeatedly. Alternatively, an aqueous solution of sodium sulfate, an aqueous sodium carbonate solution, an aqueous solution of lithium bromide, etc. can also be used. The solidification and melting temperatures of these heat absorbing and dissipating materials are 4.5 degrees Celsius higher than those of the former, at around 32 to 33 degrees Celsius, so when using them for stuffing for bedding and clothing, calcium chloride is used in consideration of comfort. Good results can be obtained by using an aqueous solution, and insulation materials for buildings that require even higher heat retention and cold retention capabilities, insulation materials for ice boxes, insulation materials for bathtubs, insulation materials for heating and cooling equipment, and other heating and cooling equipment. Among them, the heat absorbing and dissipating materials 4 described above can be selectively used.

ることができる。 The present invention has been described above based on the embodiments, but the present invention provides a heat absorbing and dissipating material 3 that performs two functions: absorbing external heat and releasing its own retained heat, in a suitable liquid-tight container. Since it is filled in a bag or the like, it is possible to keep bedding items such as futons, pine mattresses, throw blankets, and kotatsu mats at an appropriate temperature regardless of the outside air or environmental temperature.Especially when used as a building material. It has the effect of being very useful as part of energy-saving measures, and can keep you warm for a long time in the winter and cool for a long time in the summer.
