工業的に多く使用されており入手しやすい。BACKGROUND ART In general, heat storage materials are broadly classified into three types: sensible heat type, latent heat type, and chemical heat type. In particular, latent heat type heat storage materials have a high heat storage density and do not require complicated equipment, making them highly practical. The present inventors have been studying a heat storage device using a latent heat storage material as a heat source for home appliances such as irons and heating trays. Pentaerythritol (Pentaerythritol)
was found to be the most suitable. Pentaerythritol has a crystal transition point at 188°C, and its latent heat of transition is relatively large, about 300 J/g. Moreover, pentaerythritol itself is widely used industrially as a raw material for resins and paints, and is easily available.

つてきた。Problems to be solved by the invention Pentaerythritol is an organic substance that is relatively stable against heat, but when exposed to high temperatures in the air for a long time, it gradually undergoes thermal decomposition and the amount of heat stored decreases. Resulting in. This is due to the influence of oxygen in the air, and if pentaerythritol is removed from oxygen, its durability will be greatly improved.
However, at high temperatures exceeding 200°C, such a decrease in heat storage may occur even in a closed system that excludes oxygen. It has been found that adding a certain type of suitable stabilizer to pentaerythritol is effective as a means of solving this problem, but the influence of metals cannot be ignored as a factor causing this reduction in heat storage. I have come to understand this.

るものである。 FIG. 7 shows this situation. This was done by mixing metal pieces of the same shape with pentaerythritol in a sealed glass test tube, heating them continuously in an atmosphere of 220°C, and measuring the change in heat storage. In the figure, compared to a sealed tube containing only pentaerythritol, iron in b,
It can be seen that the heat storage amount decreases greatly in all cases where aluminum (c), brass (d), and copper pieces (e) are mixed. This result indicates that metal is not suitable as a heat storage container material that comes into direct contact with a heat storage material based on pentaerythritol.In particular, the fact that copper and aluminum, which have excellent heat conductivity, cannot be used means that metals are not suitable for heat storage devices. can be a fatal flaw.
本発明はこのような問題点に着目してなされた

熱装置を提供することを目的とするものである。 The present invention has been made with attention to these problems, and the durability of the heat storage material is not reduced even when the heat storage material is housed in a metal heat storage container, and it can be easily sealed from the outside air. The purpose of this invention is to provide a heat storage device with excellent durability.

る。Means for Solving the Problem In order to solve this problem, the present invention forms a fluororesin coating on the inner surface and the periphery of the opening of a metal heat storage container having an opening, and a lid member is placed on the periphery of the opening. The structure is such that the opening is sealed when attached.

を向上するため蓄熱容器の密閉が容易となる。Effect With this configuration, fluororesin is extremely inert to heat storage materials and at the same time has high heat resistance.
Even at high temperatures of 200°C or higher, the fluororesin coating formed on the inner surface of the heat storage container prevents the heat storage material from coming into direct contact with the metal container. Furthermore, the fluororesin coating formed around the opening of the heat storage container improves airtightness with the lid member, making it easier to seal the heat storage container.

In FIG. 1, reference numeral 1 denotes a metal heat storage container having an opening 2, and a fluororesin coating 3 having a thickness of about 15 μm to 5 mm is formed on the inner surface. 4 is a heat storage material mainly composed of pentaerythritol, which is filled into the heat storage container 1 through the opening 2. 5 is a heating body for heating the heat storage material 4. A fluororesin coating 6 is formed on the opening periphery 2A, and a lid member 7 is pressed against this surface with screws 8 to close the opening 2.
is sealed.

に接触しないように保護しているからである。 FIG. 2 is a graph showing the effect of the fluororesin coating 3 formed on the inner surface of the heat storage container 1 in the above configuration. Heat storage container 1 is heated to 220℃ by heating element 5
The heat storage material 4 is heated at a constant rate, and the change in the amount of heat stored in the heat storage material 4 at that time is measured. In the figure, A is a fluororesin coating 3 made of tetrafluoroethylene resin (PTFE), B is a tetrafluoroethylene-perfluoroalkoxyethylene copolymer resin (PFA), and C is a tetrafluoroethylene-perfluoroalkoxyethylene copolymer resin (PFA). Hexafluorinated propylene copolymer resin (hereinafter referred to as FEP)
It can be seen that the decrease in heat storage amount of the heat storage material 4 is significantly improved in both cases compared to case 2 in which the fluororesin coating 3 was not formed. This means that the continuous heat resistance temperature of the fluororesin coating 3 is
PTFE and PFA are as high as 260℃ and FEP is 220℃, so
This is because the heat storage material 4 is protected from contacting the metal surface of the heat storage container 1 even at high temperatures.

久寿命に大きく影響していることが分かる。 FIG. 3 shows experimental results showing that fluororesin is more inert to pentaerythritol than other high melting point resins. As in the case of Figure 7, each resin piece of the same shape was mixed with pentaerythritol in a glass test tube, sealed, and continuously heated in an atmosphere of 220°C to measure the change in heat storage amount. This is what was measured. In the figure, A is a sealed tube containing only pentaerythritol, B is a fluororesin (PTFE), C is an epoxy resin, D is a polyimide resin, and E is a mixture of polyamide resin (66-nylon) pieces. It can be seen that B, which is a mixture of resin, shows less decrease in heat storage amount than the others, and is inert to pentaerythritol.
It can be seen that resins other than fluororesin greatly affect the durability life of pentaerythritol.

熱材４の耐久寿命に影響を与えるのを防止する。 As described above, by forming the fluororesin coating 3, which is inert to pentaerythritol, on the inner surface of the heat storage container 1, the influence of the metal on the heat storage material 4 can be eliminated. At the same time, the fluororesin coating 6 formed on the opening periphery 2A exhibits elasticity as a resin even at high temperatures, so that the sealing performance with the lid member 7 is maintained, and the outside air enters the heat storage container 1, thereby preventing the heat storage material 4 from entering the heat storage container 1. to prevent the durability life of the product from being affected.
次に本発明の他の実施例について説明する。 Next, other embodiments of the present invention will be described.

対する部分だけであつてもよい。 FIG. 4 shows a second embodiment of the invention. This is done by forming a fluororesin coating 6 on the opening periphery 2A of the heat storage container 1, and also forming a fluororesin coating 9 on the lid member 7, and by welding both fluororesin coatings 6 and 9 to each other, the opening 2A is formed. is sealed. With this configuration, the opening periphery 2A and the lid member 7 can be reliably sealed without using screws or the like.
The fluororesin film 9 is preferably provided on the entire surface of the lid member 7, but may be provided only on the portion facing the opening periphery 2A as shown in the figure.

簡単に開口部２を封止できる。 FIG. 5 shows a third embodiment of the invention. This seals the opening 2 by directly welding a lid member 10 made of a fluororesin film to a fluororesin coating 6 formed on the periphery 2A of the opening. Note that sealing can be achieved in the same way by using a fluororesin plate instead of the fluororesin film. With these configurations, the opening 2 can be sealed more easily than in the second embodiment.

破れたりする心配がない。 Further, as shown in the fourth embodiment of FIG. 6, if the top of the lid member 10 made of fluororesin film is further pressed with the cover 11, there is no need to weld the lid member 10 and the fluororesin coating 6, and the lid There is no fear that the member 10 will break unexpectedly.

金属の影響が問題になる蓄熱材の場合は上記実施
例と同様の構成で同様の効果が得られる。 In addition, in the above example, a heat storage material mainly made of pentaerythritol was described, but for practical purposes, it is preferable to use it in a closed system, and in the case of a heat storage material where the influence of metal is a problem, the above implementation should be carried out. Similar effects can be obtained with the same configuration as in the example.

と金属との両方の影響を取り除くことができる。 For example, paraffin wax is used as a low-temperature heat storage material by utilizing its latent heat of melting.
If it is used at a heat storage temperature of 100℃ or less, there is no problem even if it is directly sealed in a metal container. However, in heat storage devices where the temperature of the heat storage material rises to around 200 degrees Celsius depending on the application, the decomposition of paraffin wax is accelerated when it coexists with metals, resulting in an extremely low durability. In such a case, according to the present invention, the influence of both the outside air and the metal can be removed.
