自动加水器原理:当蒸煮器内水面超过输气管的管口平面时贮水瓶内大气压力,即受到封闭,流不出水来;当蒸煮器内水份蒸发时,输气管的管口即露出水面,大气即复进入输气管,作用于贮水瓶内水面,贮水因自身重力即自动流入蒸煮器内;当至输气管口平面时,贮水 Automatic water heater principle: when the digester water surface exceeds the pipe mouth of the pipe when the atmospheric pressure inside the water bottle, that is closed, no water flow to; when the digester water evaporation, the pipe mouth is exposed water , The atmosphere that is complex into the gas pipe, acting on the surface of the water bottle, water storage due to gravity that is, it automatically flows into the digester; when the gas pipe port plane, the water storage
