PROBLEM TO BE SOLVED: To provide a washer which jets a liquid to an entire washed object and prevents washing failure by simple structure and control.SOLUTION: A liquid storage part 4 is connected to a lower part of a washing tank 2 for housing a washed object. A washing nozzle 3 is rotatably held by a support member 12 arranged in the washing tank 2, and has a nozzle hole for jetting a liquid supplied through the support member 12. Circulation means 8 circulates and supplies the liquid in the liquid storage part 4 to the support member 12 of the washing nozzle 3. The washing nozzle 3 is formed of a hollow member of which a longitudinal center part is held by the support member 12 rotatably around an axis along a vertical direction, and has a nozzle hole for jetting the liquid in directions except for the vertical direction. A flow speed of the liquid jetted from the nozzle hole is changed by changing a circulation flow rate by the circulation means 8 during circulation by the circulation means 8.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】簡易な構成および制御で、被洗浄物の全体に液体を噴射して、洗浄不良を防止できる洗浄器を提供する。【解決手段】被洗浄物が収容される洗浄槽2の下部には、液貯留部4が連接される。洗浄ノズル3は、洗浄槽2内に設けられる支持部材12に回転可能に保持され、支持部材12を介して供給される液体を噴射させるノズル孔が形成されている。循環手段8は、液貯留部4の液体を洗浄ノズル3の支持部材12へ循環供給する。洗浄ノズル3は、鉛直方向へ沿う軸まわりに回転可能に、長手方向中央部が支持部材12に保持され、鉛直方向以外に液体を噴射させるノズル孔を有する中空部材から形成される。循環手段8による循環中、循環手段8による循環流量を変更することで、ノズル孔から噴射される液体の流速を変える。【選択図】図1
