Ih電子鍋的ih是什麼意思

"IH" in an IH rice cooker or IH cooking appliance stands for "Induction Heating." Induction heating is a cooking technology that uses electromagnetic induction to heat the cooking pot directly, rather than using thermal conduction from a heating element.

Here's how it works:

1. The cooking pot is made of a magnetic material, such as cast iron or certain stainless steels.
2. When the pot is placed on the cooking surface, an electromagnet beneath the surface generates a magnetic field.
3. The magnetic field induces an electric current in the pot, which generates heat directly in the pot itself.

This method of heating is highly efficient because the heat is generated directly in the pot, rather than in a heating element that then transfers heat to the pot. This can result in faster cooking times and more precise temperature control.

IH rice cookers and other IH cooking appliances are popular in Japan and other parts of Asia, and are known for their ability to cook rice evenly and to a high standard. They are also commonly used for other types of cooking, such as stewing, boiling, and steaming.
