It is 1. The heating device 1 is composed of a heater unit 2, a regulator 3 for adjusting the heater output, a heat insulating material 4 provided outside the heater unit 2, and a cord 5. The electric cushion has a cord when heating the cushion, which limits movement of the body. In order to eliminate this limitation, it has been desired to develop a cordless cushion. In order to satisfy the above-mentioned demand, it is a conventional example considered prior to the present invention to create a heating device using a latent heat storage material. That is, since latent heat storage materials that utilize latent heat have advantages such as a large amount of heat storage per unit weight and the ability to maintain a constant temperature, attempts have been made to use them in cordless body warming devices. Figure 3 shows
1 shows a conventional heating device (cushion) 1 that was conceived prior to the present invention. The latent heat storage material is enclosed in a container made of a film laminated with plastic film and metal foil. When the heating area is large, a plurality of the containers are arranged in a row to form a pine shape to obtain the required area. Further, the container is provided with a heater for storing heat in the heat storage material, and a heat storage unit 6 is provided.
is configured. A heat storage cord 7 is attached for energizing the heater during heat storage. After heat storage, the heat storage cord is removed. If heat storage is performed in a dedicated device other than the cushion, the heater is unnecessary. The conventional cushion is further configured to have a heat insulating layer 4 made of a flexible heat insulating material such as soft urethane foam on the outside of the heat storage unit 6 to suppress heat release.

るようになつた。Problems to be Solved by the Invention When considering, for example, a heat storage cushion as a conventional warming device, the above configuration has the following problems. In other words, when a person sits on a cushion with a built-in heat storage material, the insulation material is compressed in the above configuration.
Its thickness is significantly reduced. Since heat insulation is strongly affected by the thickness of the heat insulating material, when the thickness of the heat insulating layer becomes thinner due to compression as described above, the heat insulation performance decreases. Therefore, the heating temperature on the side where the cushion and the human body are in contact becomes high and too hot. In the case of electric seat cushions, the temperature can be controlled by a regulator, so this problem does not arise as described above, but in the case of latent heat storage type cushions, the output is constant, so the above-mentioned problem has started to occur.

があつた。 As for the above-mentioned problem, when a person sits on a latent heat storage cushion, the thickness of the insulation should be determined so that a comfortable temperature can be obtained. However, in this case, there was a problem that the thickness of the heat insulating layer was too thick to be practical.

It is equipped with large insulation material.

Therefore, comfortable heating can be obtained.

ができる。Embodiment FIG. 1 is a sectional view showing an embodiment of a heating device, such as a cushion, of the present invention. Note that the same substances are given the same symbols. In FIG. 1, a heating device 1 has a latent heat storage material such as sodium thiosulfate pentahydrate or sodium acetate trihydrate sealed in a container made of a film laminated with plastic film and metal foil, and further heats the container. It consists of a heat storage unit 6 provided with a heater, a heat insulating layer 8, and a heat storage cord 7 for storing heat. In this configuration, when storing heat, it is connected to a power source via a heat storage cord to store heat. After storing heat, remove the heat storage cord and use it. Therefore, it can be carried freely.

す。 The feature of the cushion of the present invention lies in the structure of the heat insulating layer 8. That is, the heat insulating layer 8 is made of a heat insulating material 9 having a high compressibility relative to the compression pressure, such as flexible polyurethane foam, and a heat insulating material 8 having a low compressibility, such as hard polyurethane foam, felt, crosslinked polyethylene foam, etc. The compression ratio is expressed by the following formula.
圧縮率＝圧縮応力が加わる前の厚み−圧縮応力が加

異和感を感じない。 Compressibility = Thickness before applying compressive stress - Thickness after applying compressive stress / Thickness before applying compressive stress x 100 Now, when applying 50 g/cm 2 as compressive stress, the insulation with large compressive force As material 9, the compressibility is
60% or more is preferable. If it falls below 60%, it will become hard and you will feel strange when taking heat. Further, as the heat insulating material 8 having a small compressive force, it is preferable that the compressibility is 20% or less. If it exceeds 20%, the thickness of the heat insulating layer becomes thick, which is not preferable. Since the heat insulating material 11 is on the side opposite to the human body, it is preferable that the compressibility is small within a range that does not impair the overall flexibility, the thickness does not decrease even when a person sits down, and the heat insulating performance does not deteriorate. Further, the heat insulating material 10 and the heat insulating material 11 may be made of the same material. The feature of this embodiment is that even when a person is sitting on the cushion, because a heat insulating material with a low compressibility is used as part of the heat insulating layer, even if the thickness of the heat insulating material with a high compressibility is reduced, the heat can still be collected. It can be easily designed to a suitable thickness. Therefore, it is possible to prevent it from becoming too hot. In addition, if a heat insulating material with a high compression rate is used on the human body side, it will be soft and will not make you feel strange when taking warmth.

みが厚くなることがなく、実用的である。Effects of the Invention As described above, according to the present invention, the heat insulating material on the side where the heat storage container and the human body are in contact is composed of a heat insulating material having a high compressibility against external forces and a heat insulating material having a low compressibility. Because of this, even when force is applied to the insulation material, the thickness of the insulation material decreases and the human body does not get too hot. In addition, because a part of the heat insulating layer uses a heat insulating material with a high compression rate, you will hardly feel any discomfort when warming yourself. Furthermore, the thickness of the heat insulating layer does not increase, which occurs when the heat insulating layer is formed only from a heat insulating material with a high compressibility, and is practical.
