This creation is the vessel of breeding fish that related what one kind is cleaned automatically,It include vessel ontology,Inclined plate and aqueduct,Wherein left,Place is fitted in the bottom in the inclined plate system setting what vessel ontology of high low dip in the right side,And it is closely sealed with four wall surface of vessel； At the low level of the upright what inclined plate of water guide piping,And its top wears vessel ontology side Hou and is bent downwardly outward,Then it is external to stretch out what vessel sheet downward for its nozzle； When being filled to relatively high level in vessel of breeding fish,The raising of fish is carried out,After a period of time,When at dirty accumulation what inclined plate low level,It injects water into vessel,Increase its water level and be more than aqueduct top nozzle,Then aqueduct can because siphon principle by accumulated at inclined plate low level it is dirty be expelled to outside vessel,Until the water level decreasing in vessel to it is equal with aqueduct top nozzle just stop water suction,Thereby repetitiousness acts the automatic cleanser for the vessel that breed fish.本創作係有關於一種自動清洗之養魚器皿，其包括器皿本體、斜板及導水管，其中左、右呈高低傾斜之斜板係設置於器皿本體內之底部適處，且與器皿四壁面密合；導水管係直立於該斜板之低位處，而其頂部穿設器皿本體一側後向外向下彎曲，則其管口朝下伸出於器皿本體外；當養魚器皿內注水至相當高度，進行魚之飼養，經過一段時間，髒污堆積於斜板低位處時，將水注入器皿內，使其水位上升且超過導水管頂部管口，則導水管會因虹吸原理將斜板低位處所堆積之髒污排出至器皿外，直到器皿內之水位下降到與導水管頂部管口相等才停止吸水，藉此反覆動作進行養魚器皿之自動清洗者。
