How is the Hotaru inner bowl heated?

Hotaru uses Induction Heating (IH) technology, which provides a more direct and evenly distributed method of heating compared with conventional rice cookers.

Inside the cooker are induction coils that generate a magnetic field. When the specially designed spherical inner bowl is placed inside the cooker and the IH system is activated, the magnetic field causes the bowl itself to generate heat.

Even Heat Distribution

Because the inner bowl itself becomes the heat source, rather than simply being heated from underneath by a conventional heating element, heat can be distributed more evenly around the spherical bowl.

This helps provide:

• More even cooking of the rice

• Consistent heat throughout the cooking bowl

• Better temperature control during the cooking cycle

• Excellent results when cooking other dishes

• More consistent results across different quantities of rice

The spherical shape of the inner bowl works particularly well with the IH system, helping heat to be distributed around the cooking chamber rather than being concentrated in one area.

Superior Keep Warm Performance

Hotaru's IH technology also works alongside its advanced keep-warm system to help maintain the rice at an appropriate serving temperature after cooking.

The combination of direct induction heating, even heat distribution and intelligent temperature control helps Hotaru maintain consistent conditions throughout both the cooking and keep-warm stages.

In short, Hotaru's IH system heats the spherical inner bowl directly, helping distribute heat more evenly and providing the precise temperature control needed to produce consistently great-tasting rice.
