How works the rice cookers

[mloo55]

Just I would like if somebody can explain how do these appliances
work? of course electrically, somebody explain me that it uses a
electromagnet......
hope you can help

It's complicated, like Hammers and Nails !

You put Water in the pan with Rice.

Place the covered pot in the cooker on top of the Heat Sensor and Press
the Switch, which completes the magnetic circuit, which in turn
completes the Electrical circuit to the Heater. In plain english you
manually close a Relay!
The heater causes the water to boil at ~ 100'C., when the water boils
away the temperature rises rapidly and exceeds the "CURIE Point" of the
Magnetic Switch, causing the switch to demagnetize and open. Pressing
the switch now will do nothing until the pot cools down a few degrees !
Several generations of Rice eaters have never tasted "Scorched Rice".

It's been almost 50 years since I last chewed a piece of Scorched Rice
with a bit of salt.
It's like an automatic toaster to bread, When is the last time you
scraped burnt Toast ?

The Curie Point Switch is an industrial Revolution for Rice Cookers. It
is virtually Fool-proof, even fools have difficulty screwing it up.

Our rice cooker seems to have a regular heating element, coupled with a
springed assembly that looks like it measures the weight of the cooking
pot. Perhaps it keeps cooking until the rate of weight decrease (due to
water evaporation) falls below a certain level.
