いる。BACKGROUND ART In general, heat storage materials are broadly classified into three types: sensible heat type, latent heat type, and chemical heat type. Among these materials, latent heat storage materials have a high heat storage density because they utilize latent heat accompanying melting or crystal transition, and do not require complicated equipment, so they are highly practical. The inventors have been investigating a heat storage device using latent heat storage materials as a heat source for home appliances such as irons and heating trays, but organic materials such as paraffin wax, polyethylene, and pentaerythritol are not suitable for heat storage. It has been found to be advantageous.

まう危険性があつた。Problems to be solved by the invention Organic substances are generally unstable to heat;
In particular, organic latent heat storage materials may gradually decompose and generate decomposed gases such as CO 2 and H 2 O when exposed to a heat storage temperature, that is, a temperature higher than the melting point or transition point. Therefore, if an organic latent heat storage material is used for a long period of time, there is a risk that these decomposed gases will accumulate in the heat storage container housing the heat storage material, causing an abnormal increase in internal pressure.

スは透孔４Ａを通つて炭素２に吸着される。 In FIG. 1, 1 is an organic latent heat storage material (hereinafter referred to as heat storage material) such as paraffin wax or pentaerythritol, and 2 is carbon such as graphite or carbon black, each of which has a partition plate 4 inside a heat storage container 3. It is hermetically sealed through. The partition plate 4 is provided with through holes 4A to allow free flow of gas. 5 is a heating body provided in the heat storage container 3. During heat storage, the heat storage container 3 is heated by the heating body 5, so that the heat storage material 1 is heated and heat is stored. After heat storage, the heat storage container 3 can be kept at a constant temperature by the heat transfer from the heat storage material 1 without heating the heating body 5. With such a configuration, even if the heat storage material 1 gradually decomposes after long-term use, CO 2 and
Even if a decomposed gas such as H 2 O is generated, the decomposed gas is adsorbed by the carbon 2 through the through hole 4A.

も見られなかつた。 For example, heat storage material 1 is pentaerythritol, carbon 2 is porous graphite (Japanese graphite EXP-200)
As a result of heating the heat storage material 1 at a constant temperature of 220° C. using the heating element 5 and holding it for 500 hours, the heat storage amount of the heat storage material 1 decreased, but no increase in the internal pressure of the heat storage container 3 was observed. Further, the decrease in heat storage amount of the heat storage material 1 was smaller than when carbon 2 was not added, and the stickiness of the heat storage material 1 that was observed when carbon 2 was not added was not observed.
この他に炭素２としてアセチレンブラツク（電

プレス充填すればよい。 In FIG. 2, layers of heat storage material 1 and carbon 2 are formed inside the heat storage container 3 and are hermetically housed without providing a partition plate inside the heat storage container 3. As a filling method, for example, after press-filling the heat storage material 1, carbon 2 may be press-filled onto the upper part.

ある。 In FIG. 3, heat storage material 1 and carbon 2 are directly mixed and sealed in a heat storage container 3. If there is a possibility that heat storage material 1 and carbon 2 may chemically influence each other, it is preferable to separate them into layers as shown in Figures 1 and 2. In the case where the heat storage material 1 and the carbon 2 are mixed in this way, there is an advantage that the storage becomes easier and the heat transfer characteristics of the heat storage material 1 are also improved.

and a base located approximately in the center of the heat storage container 3 and forming a vaporization chamber 6. The heat storage material 1 is press-filled into the heat storage container 3, and carbon 2 is press-filled onto the top of the heat storage material 1, forming respective layers. A heating element 4 is embedded in the base 5. Furthermore, a plurality of heat transfer fins 7 are provided inside the heat storage container 3 to improve heat conduction between the heat storage material 1 and the base 5. A base lid 8 is fixed to the upper surface of the base 5 with screws 9, and a packing 10 is provided between the base 5 and the base lid 8, and a heat storage container 3 and a vaporization chamber 6 are provided.

取付けられている。 Water 12 for steam generation is stored in the tank 11, and when the steam button 13 is operated, the opening/closing rod 14 moves up and down to open the drip opening 1 of the drip nozzle 15.
6 is opened and closed to drip water into the vaporization chamber 6.
Steam generated in the vaporization chamber 6 is ejected from the ejection hole 17 communicating with the vaporization chamber 6 to the bottom surface of the base 5. Further, the temperature adjustment lever 18 is connected to a temperature controller (not shown), so that the temperature of the base 5 can be adjusted. The heating body 4 is electrically connected to a power supply terminal 19 via a temperature regulator, and when heating the heating body 4, a power source is connected to the power supply terminal 19 to supply power. A cover 20 covers the base 5 from above, and a handle 21 is attached to the top of the cover.

原因になつたりするおそれがない。 With the above configuration, when a power supply is connected to the power supply terminal 19 and the temperature control lever 18 is set to the steam scale and the power is turned on, the base 5 is heated to the set temperature by the heating element 4, and the heat storage container 3 and heat transfer fins 7 are heated. The heat storage material 1 is also heated and stores heat. When ironing, even if the power supply is disconnected from the power supply terminal 19, the temperature drop of the base 5 is suppressed by the heat transfer from the heat storage material 1, so you can work without a power supply and without worrying about the power cord. can be done. Moreover, if it is desired to generate steam during work, the steam button 13 may be operated. At this time as well, the heat storage material 1 suppresses the temperature drop in the vaporization chamber 6, so that a sufficient amount of steam can be obtained. When used repeatedly over a long period of time in this way, the heat storage material 1 gradually decomposes and generates decomposed gas, but the carbon 2 adsorbs this decomposed gas, causing the internal pressure of the heat storage container 3 to rise. There is no risk that the base lid 8 will rise and the heat storage material 1 will leak outside through the gap, staining clothes or causing burns.
また、炭素２は加圧充填されているのでシール
材の機能も果たし、たとえパツキング１０が老化
してきたとしても蓄熱容器３の密閉性は確保され
るという効果もある。 Furthermore, since the carbon 2 is filled under pressure, it also functions as a sealing material, and even if the packing 10 ages, it has the effect of ensuring the airtightness of the heat storage container 3.

る。Effects of the Invention As described above, by making an organic latent heat storage material coexist with carbon and sealingly housing it in a heat storage container, it is possible to prevent the internal pressure of the heat storage container from abnormally increasing even if the heat storage material is used for a long period of time. Therefore, it is possible to provide a heat storage device that is highly safe and has excellent durability.
