高温にすることはできない。 In general, heat storage materials such as water, clay, and
Sand, gravel, heat-resistant bricks, synthetic oils such as silicone oil,
Paraffin wax, natural oils, and the like, which have latent heat of melting, are used, and the method for heating them is to place them in a high-temperature atmosphere and transfer heat from the outside.
The heat storage material is directly heated by the heater. It is heated by heat exchange by bringing it into contact with a high-temperature fluid. Methods such as heating in a microwave oven are used.
However, it takes time to raise the temperature and is not efficient. Since the heat storage material and the heater come into contact with each other, certain precautions must be taken if the heat storage material decomposes at high temperatures or is flammable. In addition, since it has heater wires and electric cords, it has a complicated structure, and is often limited in terms of where and how it can be used. For this reason, the device becomes larger.
For this purpose, a substance that absorbs high frequency waves is required, and since the relevant substance contains water, -OH, etc., it cannot be heated to high temperatures.

誘導加熱の原理は発熱体にうず電流を誘起し、こ
の電流により発熱体自体を熱するものである。 Electromagnetic induction heating is starting to become popular as electromagnetic cookers, etc. The heating device itself does not generate heat and is safe, unlike combustion, there is no exhaust gas, so it is clean, it has high thermal efficiency (about 80%), and when heating Its advantage is that the rise time is extremely fast. The principle of electromagnetic induction heating is to induce eddy current in a heating element, and this current heats the heating element itself.

大する。 Therefore, according to the present invention, a heating element that generates heat by electromagnetic induction is covered with a heat storage material, and the heat storage material is sealed in a sealed body made of a magnetically permeable material. All that is required is to induce an eddy current in the material to generate heat, which is then transferred to the heat storage material and stored, resulting in an extremely simple structure and a wide range of applications.

ほとんど流れないことから加熱されないため不適
当である。 The heating element that can be used is not limited in material or shape as long as it generates heat by inducing eddy current by electromagnetic induction, and metals and alloys such as iron, nickel, stainless steel, and aluminum are selected. However, it is not suitable for powdered substances because almost no eddy current flows and therefore they are not heated.

面、潜熱の面から好ましい蓄熱材であつた。 Since the heat storage material is heated by conduction of the heat of the heating element, it is desirable to have a large contact area with the heating element. Therefore, liquid substances (water, synthetic oil, etc.), grease-like or wax-like substances (paraffin wax, wax, higher fatty acids, etc.) are used. In particular, a wax-like substance that melts at high temperatures is a preferable heat storage material in terms of heat conduction through convection and latent heat.
密封体については磁気透過性物質であり、蓄熱
体を密封できる材質が選ばれるが、形状が任意で
あり、シールも容易な合成樹脂が最も好ましい。 For the sealing body, a magnetically permeable material that can seal the heat storage body is selected, but synthetic resin is most preferable since it can have any shape and is easily sealed.

温、加熱などに供する。 Inside the sealed body 1 made of polycarbonate, which is a heat-resistant synthetic resin that does not affect magnetism, there is a heating element 3 made of iron plate that generates heat by electromagnetic induction, and a paraffin wax (melting point 80
℃) is enclosed in a heat storage material 2. 4 is an electromagnetic induction device, which is used only when storing heat. The size of the heating element 3 used was an iron plate of 150 mm x 150 mm x 1 mm, and the weight of the heat storage material 2 was 200 g. The frequency of the electromagnetic induction heating device 4 is 20KHz. The heat storage method is as follows. That is, the sealed body 1 is placed on the electromagnetic induction heating device 4. When the electromagnetic induction heating device 4 is energized in this state, the heating element 3 generates heat almost instantaneously and heats the heat storage material 2. The heat storage material 2 melts from the part that is in contact with the heating element 3, and is successively melted by convection. After the heat storage material 2 is completely melted, the electromagnetic induction device is turned off and heat storage is stopped. The sealed body 1 containing the heat storage material 2 stored in this way is moved to an arbitrary location, and the human body is heated by latent heat and sensible heat.
Used for heating, keeping warm, and heating domestic animals, cooked food, indoor atmosphere, etc.
