Where to Find Accurate Block Diagrams for Consumer Electronics Like Ovens With MCU & EMI Filters

Hi collegues,
Does anyone know where I can find accurate block schemes for consumer electronic products?I need it because for personal project and fun I would like to build my own electrical oven complete of safety systems, EMI filters, microcontroller, etc. Any suggestion is very welcomedThanks in advance
Cheers!

Hi Andrea-Are we talking about a block diagram for a modified toaster oven like you would use for reflow soldering?  If you are, here's one: Toaster Oven RetrofitIf you're looking for the block diagram of an oven like you might find in a kitchen, I'll need to look in a different direction (although much of the same block diagram still applies).-Rick

Hi Rick,Thanks a lot for the reply and for the scheme, is exactly the kind of scheme I was looking for. To answer your question, yes I mean a kitchen oven, with LCD display to select items in the menu and such. I think it is a pretty good and complete project which involves a bit of everything. To come back to the scheme I have few questions. In your experience  The DC regulator that powers the micro can be a flyback converter straight from the AC? The relay block is actually a rectifier? Thanks in advance for the help
Kind Regards
Andrea

Andrea,The block diagram that Rick provided is at a very high level.  I'd expect that the rectifiers would be included in the DC regulator block. The relay block would not include rectifiers. As far as a block diagram for a kitchen oven, I'd expect it to be similar enough to get started. Have you checked in/around your kitchen oven? Most that I've seen have wiring diagrams at least to assist the repair person in troubleshooting.For what it's worth, I know from experience that some kitchen ovens do NOT have adequate  AC line transient protection.
