却現象を起こす問題があつた。Configuration of conventional example and its problems As shown in FIG. 1, in a conventional heat storage device of this type, a heater 5 is attached to a heater mounting surface 4 of a container 3 containing a latent heat storage material 1 and a supercooling prevention material 2. A temperature detection line 7 for detecting the temperature of the latent heat storage material 1 was attached to the opposite side surface 6 opposite to the heater mounting surface 4. A controller 8 is provided which controls the energization of the heater 5 based on the temperature detection signal from the temperature detection line 7. Furthermore, the heater 5 was surrounded by a heat insulating material 9 from the outside. In this configuration, a portion of the heat insulating material 9 is
When the area is covered with a heat insulating material 10 such as a seat cushion, the amount of heat dissipated in that area decreases, and the temperature rises compared to other areas not covered with the insulating material 10. Controller 8
controls the energization to the heater 5 based on the total impedance value of the temperature detection line 7, but the heat insulating material 10
The contribution of impedance changes in areas covered by high temperature rises to the overall impedance was small. In this case, since the controller performs control based on the temperature of the portion not covered with the heat insulating material 10, the temperature of the portion covered with the heat insulating material increases further. Then, since the heat resistance temperature of the supercooling prevention material 2 mixed in the latent heat storage material 1 is exceeded, the function of the supercooling prevention material 2 is lost, and after the latent heat storage material 1 is melted, power supply to the heater 5 is stopped. However, even if heat dissipation was started, there was a problem that heat could not be dissipated at the freezing point, which caused a supercooling phenomenon.

熱熱量が利用できないという問題もあつた。 Further, even when the surface of the heat insulating material 9 was not covered with the heat insulating material 10, a temperature difference occurred between the end portion 11 and the center portion 12 of the container 3 due to the difference in the amount of heat dissipated. Therefore, after melting the latent heat storage material 1 by the heater 5, when using the radiated heat amount for heating, check that the center part 12 of the container 3 has melted and then shift to heat radiation to ensure that the end part 11 has not yet melted. First, there was the problem that the amount of heat released could not be utilized.
さらに、中央部１２及び端部１１が全て融解
後、放熱させると、端部１１が中央部１２よりも
早く放熱が完了し、温度差が生じ、採暖暖房の快
適感が損なわれるという問題もあつた。 Furthermore, if heat is radiated after the central part 12 and end parts 11 are all melted, there is also the problem that the end part 11 completes heat radiation earlier than the central part 12, creating a temperature difference and impairing the comfort of the heating system. Ta.

的とする。Purpose of the invention The present invention solves such conventional problems,
During heat storage by the heater, a part of the surface of the insulation material is covered with a heat insulating material, and the temperature of the latent heat storage material in that part increases, the function of the supercooling prevention material is lost, and supercooling occurs during heat dissipation. In addition to preventing this from happening, it also eliminates the possibility that there is a difference in melting completion time between the center and the edges of the container during heat storage, which could delay the transition to heat radiation use. The purpose of the present invention is to eliminate the occurrence of temperature differences between areas that impair the comfort of heating and heating.
発明の構成
この目的を達成するために、本発明はヒータ上
及び断熱材表面にアルミ層を貼り付けたものであ
る。Structure of the Invention In order to achieve this object, the present invention has an aluminum layer pasted on the heater and on the surface of the heat insulating material.

うとしても、熱拡散を良くし、容器の温度上昇を
小さく抑える。 With this configuration, the aluminum layer on the heater can improve heat transfer between the high-temperature part and the low-temperature part of the container, thereby reducing the temperature difference. Furthermore, part of the surface of the aluminum layer on the surface of the insulation material is covered with insulation material,
Even if the amount of heat dissipated from the heat insulating material decreases and the temperature rises, it improves heat diffusion and keeps the temperature rise in the container small.
実施例の説明
以下、本発明の一実施例を第２図を用いて説明
する。なお、第２図中、第１図と同一部材につい
ては同一番号を付している。DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. In FIG. 2, the same members as those in FIG. 1 are given the same numbers.
第２図において、ヒータ５の上には容器側アル

により遅れて融解する時間差が小さくできる。 In the above configuration, when the heater 5 heats and stores heat in the latent heat storage material 1, if the surface of the insulation material 9 is covered with a heat insulating material 10 such as a cushion, the amount of heat released from the insulation material 9 decreases and the temperature tends to rise. However, due to the heat conduction of the aluminum layer 14 on the heat insulating material side, the heat is diffused to the portion not covered with the heat insulating material 10. Furthermore, if the temperature of the covered portion of the container 3 rises, the heat is diffused by the heat conduction of the container-side aluminum layer 13, thereby suppressing the temperature rise to a small level. If the control temperature of the controller 8 is set near the melting point of the latent heat storage material 1, the temperature of the latent heat storage material 1 in the container 3 corresponding to the portion covered with the heat insulating material 10 will be lower than that of the supercooling prevention material 2. Do not exceed the heat-resistant life temperature. Therefore, occurrence of overcooling can be prevented. Furthermore, even when not covered with the heat insulating material 10, when heating and storing heat by the heater 5, the amount of heat dissipation is made uniform by the heat insulating material side aluminum layer 14, and the temperature of the container 3 is made uniform by the container side aluminum layer 13. Therefore, the time difference in which the end portion 11 of the container 3 melts later than the center portion can be reduced.

くなる。 Furthermore, after melting the latent heat storage material 1, when using the radiated heat amount for heating and heating, as described above,
Due to the effects of the heat insulating material side aluminum layer 14 and the container side aluminum layer 13, the difference in heat dissipation completion time between the end portions 11 and the center portion 12 can be reduced, and the sense of comfort will not be impaired.

う効果がある。Effects of the Invention As described above, according to the heat storage device of the present invention, the container-side aluminum layer is attached on the heater, and the heat-insulating material side aluminum layer is further attached to the surface of the heat-insulating material. Even if a portion of the surface is covered with a heat insulating material such as a cushion, the heat diffusion of the heat insulating material surface by the aluminum layer on the insulating material side and the equalization of the container temperature by the aluminum film on the container side prevents temperature rises due to the heat resistance of the supercooling prevention material. It is possible to prevent overcooling of the presser foot below the life temperature. Furthermore, even if the container is not covered with heat insulating material, the difference in melting completion time between the center and the edges of the container will be small when the container is heated and melted. It can save time. Furthermore, when the amount of radiated heat is used for heating and heating, the temperature difference and the difference in heat radiation completion time between the center and the ends of the container are reduced, so that the sense of comfort is not impaired.
