PROBLEM TO BE SOLVED: To provide a washing process of a nursing device which removes fouling components hard to remove in a receiver jar and the like before washing to enhance the washing efficiency and which washes out the accretion that could not be discharged by natural drainage after washing to enhance the washability and safety.SOLUTION: The washing process of the nursing device is provided with a downward rotation type tap water spray nozzle to wash the inside of the receiver jar by jetting water for a fixed time before and after the washing, which is connected with the water supply via an on-off valve in addition to an upward washing liquid spray nozzle to wash the inside of the receiver jar by circulating and jetting the washing liquid during circulation washing. Water is sprayed to the inside of the receiver jar for 30 seconds before the washing of the whole of a milker car and for 15 seconds after the washing.COPYRIGHT: (C)2008,JPO&INPIT【課題】 レシーバージャー内部等の除去しにくい汚れ成分を洗浄前に除去して洗浄効率を高めると共に、洗浄後に自然排水で排出できなかった付着分を洗い流し、洗浄性を高めると共に安全性を向上させる。【解決手段】 循環洗浄中に洗浄液を還流させて噴出させレシーバージャー内部を洗浄する上向きの洗浄液スプレーノズルに加えて、開閉弁を介して上水道に接続され、洗浄の前及び洗浄後に水を一定時間噴出させてレシーバージャー内部を洗浄する下向きの回転式上水スプレーノズルを設け、ミルカー全体の洗浄前30秒、洗浄後15秒間レシーバージャー内部に水をスプレーする。【選択図】 図1
