If you have spent any time looking at the Zojirushi rice cooker lineup, you have probably noticed the letters IH on certain models. IH stands for Induction Heating, and it represents one of the more meaningful upgrades a rice cooker can have. It is also one of the more misunderstood. People often assume induction heating means faster cooking. It does not. What it actually means is more even, more precise, and more responsive heat. And in a rice cooker, that translates directly into better rice. <\/p>\n\n\n\n

In this month’s Back to Basics, we are unpacking how induction heating works, what makes it different from a conventional heating element, and why it is such a natural fit for cooking rice. We will also share the story of Zojirushi’s first IH rice cooker \u2014 a small but significant moment in the history of home cooking \u2014 and walk through the current Zojirushi IH lineup so you can see exactly where the technology fits in. <\/p>\n\n\n\n

What Is Induction Heating?<\/strong> <\/h2>\n\n\n\n
\"Depiction<\/a><\/figure>\n\n\n\n

A conventional rice cooker uses a heating element \u2014 typically a metal coil at the bottom of the unit \u2014 that gets hot when electricity passes through it. That heat then transfers from the element to the inner cooking pan, and from the pan into the rice. It is reliable and effective, and it has been the standard method for decades. (For more on how conventional models work, see our Back to Basics: Conventional Rice Cookers<\/a> post.) <\/p>\n\n\n\n

Induction heating works on a different principle entirely. Instead of generating heat in a coil and transferring it to the pan, an IH rice cooker turns the inner cooking pan itself into the heat source. <\/p>\n\n\n\n

Inside an IH rice cooker, copper coils are wrapped around the body of the unit. When the rice cooker is switched on, an alternating electric current runs through those coils and creates a rapidly fluctuating magnetic field. The inner cooking pan, which is made from a magnetic material, sits inside that field. As the magnetic field passes through the pan, it induces a small electric current in the metal of the pan itself. The pan resists that current, and that resistance is what produces heat. The pan effectively heats itself, from the inside of the metal outward. <\/p>\n\n\n\n

The result is heat that originates in the cooking pan itself rather than radiating up into it from below. There is no transfer step. The pan is the burner. <\/p>\n\n\n\n
