PROBLEM TO BE SOLVED: To provide a high-pressure washing device that applies no load on a high-pressure pump, when injection from a jet gun nozzle is interrupted, and can promptly inject wash water again when the injection is resumed.SOLUTION: A high-pressure washing device comprises: a nonreturn valve 40, which is installed in a second water channel 12 from a switching valve 20 to a sub hose 5; a first pressure sensor 71, which detects pressure of the second water channel 12 on downstream side of the nonreturn valve 40; and a control means 81, which opens and closes a pressure-adjusting valve 50 based on a detection value of the first pressure sensor 71. The control means 81 opens the pressure-adjusting valve 50 when the detection value of the first pressure sensor 71 reaches a preset reference value.SELECTED DRAWING: Figure 1

    【課題】ジェットガンノズルの噴射中断時には高圧ポンプに負荷を加えることがなく、噴射再開時には洗浄水の再噴射を速やかに行うことができる高圧洗浄装置を提供すること。【解決手段】切換弁20からサブホース5までの第2水流路12に設けた逆止弁40と、逆止弁40の下流側の第2水流路12の圧力を検出する第1圧力センサ71と、第1圧力センサ71の検出値に基づいて調圧弁50を開閉する制御手段81とを有し、制御手段81では、第1圧力センサ71での検出値があらかじめ設定した基準値に達した場合に、調圧弁50を開とすることを特徴とする。【選択図】 図1
