1. The inside of the heat pipe is a spiral electric heating wire, and the outside is a metal pipe. The insulating material is filled between the metal pipe and the heating wire, generally crystalline magnesium oxide. Since it is sealed, the water that is burned does not affect the water quality.
2. The principle of heat pipes is to use electric resistance to generate heat and heat the water. This process is the conversion and transfer of energy, which does not produce other by-products that are harmful to the body.
3. The hot part is isolated from the water or directly contacted with the electric heating rod, which is actually the same. The heating rod in the electric heating rod is the heating wire, and there is a layer of insulation between the outer surface of the electric heating rod, so the heating wire and the water are not in direct contact, and direct contact is not allowed, otherwise the water should be charged when boiling water. . Regardless of the method used, the heat generated by electric heating must be transferred to the water to boil the water, which is the key. In addition, like the rice cooker, the electric hot pot is also separated and heated, and it is harmless to the human body.
