The cheap cookers use a mechanical setup as there are no electronics. I have the cheapest Zojirushi 3-cup cooker where you just push down a lever. That lever mechanically latches a spring loaded mechanism that closes the heating element switch. The temperature will stay relatively stable as the water absorbs the heat keeping it at around 100 C. Once the water is evaporated from the bottom the temperature rises which trips a bimetallic mechanism releasing the spring loaded lever opening the heater switch. Stupid simple.
- kjellsbells 3y agoTangential, but one reason zojirushi is a buy it for life product is because you can get spare parts for a very long time. I have a 20 year old zj with no fundamental failures beyond the cookpot getting old and dented, and zj part replacements are easy and cheap.

- gomox 3y agoDisappointing aspect indeed, but the battery is only relevant to people that use the clock to set cooking times a lot AND ALSO keep their rice cooker unplugged. The intersection of those 2 groups is likely minimal, and the slight inconvenience of setting the time for the aforementioned group is not that bad.

- MisterTea 3y agoGood point. I haven't looked at mine but perhaps it is.
