摘要： PURPOSE:To prevent the formation of the sediment of a stuck matter on an inside wall by providing a water supplying means ejecting along the inside wall of the main tank body and an over-flow tank discharging washing water overflowing from the tank main body and a circulation means ejecting circulating water into the tank main body towards the lower part of the tank main body. CONSTITUTION:Water supplying means 4 is equipped in the upper part of the tank main body 2 along the inside wall, and provided water shower pipe 10 for supplying water, thereby ejecting supplied fresh water from ejecting nozzle 10a towards downside direction to along the inside wall of the tank main body 2. Water circulating means 8 is equipped in the down side of an inner part of the main tank body 2 along the inside wall and provided with the shower pipe 12 for circulation, ejecting supplied circulated water from the spouting nozzle 12a toward a corner of a bottom of the tank main body 2, and the circulation pump 14. The stuck matter and the sediment on the inside wall of the tank main body 2 removed into washing water is made overflow into the overflow tank 6 attending on supplying fresh water and wash water, and introduced into discharging pipe 30 through pipe 28. In the case of updating of washing water, an automatic valve 22 is opened and the water is drained rapidly through branching flowing path 20 by the circulation pump 14.
