Weekly Progress
In the last week, My group offer engineering application and shere
the work for each person. I’m do about triac circuit and find information
about interface rice cooker. Next , Sundays ago. My group make
experiment cook thr rice of TOSHIBA. Results , Can see that Rice
cooker will treat temperature at 100 degree celsius for check water in a
rice cooker peter. This treatment temperature for protect rice stick pot.
If water within pot that peter. It will up terperature at 134-140 degree
celsius for drain the steam out from pot. During this period, user don’t
open the lid because high steam pressure and it is danger for user.
In the triac circuit. We use circuit for control operation of coil all 3
coil. So, This circuit connect with microcontroller but have to isolated
circuit hedge between micro with circuit triac for protect Microcontroller
damage. Isoted and zero-crossing circuit, We use is photoisoted and
zero-cross number MOC3061. Next week, We will gather all circuit of
rice cooker and calculation of R,L and C for the circuit work.
