In the template of WEp1 ,what the definition between the words" water closet" and "blow-out fixture" according to the table WEp1-3 (flush fixture data)? (Plz no literally meanings on these words.) Since I've searched the toilet types,there are two main kinds: "Siphon"&"Wash Down",I'm still not so sure if the "water closet" equals to "Siphon" and "Blow-out fixture" refers to "Wash down"?

Ivy, I'm a little confused by your question. Can you try rephrasing it?

Since I searched the photos of " water closet" and "blow-out fixture",they are all refer to toilets. So I wonder what are the differences between them?

They likely refer to the bed pan flush valves in patient bathrooms. The bed pan is often a higher water use rate than the regular flush. Engineers often miss adjusting the bed pan flush valve even if the toilet meets LEED limits so you need to coordinate that with them. Otherwise, blow down fixtures are typically in cooling towers which has its own credits and wouldn't be counted in this credit spreadsheet.

Blowout fixtures are different from bed pan washers. The latter are also typically higher flow, but the don't have to be. Susan, cooling towers are blowDOWN; toilets are blowOUT. Blowout fixtures insert a high flow of water into the waste line to flush out potential clogs in the system. Imagine, for example, what you would need if people flushed wipes regularly (which some do, and that's a serious problem). These are no longer commonly used, but they still exist.
