CLEANING DEVICE

PROBLEM TO BE SOLVED: To provide a cleaning device which can carry out temporary cleaning of jetting cleaning water at high pressure, and main cleaning of jetting cleaning water containing fine air bubbles.SOLUTION: A cleaning device includes: a dissolution tank 3; an introduction pipe 4 which introduces a mixture of cleaning water and gas into the dissolution tank 3; a pump 5 which generates the mixture of the gas and the cleaning water by introducing the gas into the introduction pipe 4 by utilizing a negative pressure in driving, and pumps it to the dissolution tank 3; a lead-out pipe 6 which discharges the cleaning water from the dissolution tank 3 and includes a first downstream lead-out pipe 7 and a second downstream lead-out pipe 8 branched on the way; a high-pressure spray nozzle 9 which is mounted on the first downstream lead-out pipe 7 and jets the cleaning water to a cleaned object at high pressure; a fine air bubble generation nozzle 10 which is mounted on the second downstream lead-out pipe 8, generates the cleaning water containing the fine air bubbles, and jets it to the cleaned object; and a valve 11 which is arranged in a branched position of the lead-out pipe 6 and switches a flow passage so that the cleaning water is jetted from either one of the high-pressure spray nozzle 9 or the fine air bubble generation nozzle 10. 【課題】洗浄水を高圧で噴射する仮洗浄と微細気泡を含んだ洗浄水を噴射する本洗浄が可能な洗浄装置を提供すること。【解決手段】溶解タンク３と、溶解タンク３に洗浄水と気体の混合体を導入する導入菅４と、駆動時の負圧を利用して導入菅内４へ気体を導入することにより気体と洗浄水の混合体を生成しこれを溶解タンク３に圧送するポンプ５と、溶解タンク２から洗浄水を排出するとともに、途中で分岐して第１下流導出菅７と第２下流導出菅８を備える導出菅６と、第１下流導出菅７に取り付けられ、洗浄水を洗浄物に高圧で噴射する高圧スプレーノズル９と、第２下流導出菅８に取り付けられ、微細気泡を含む洗浄水を生成し、これを洗浄物に噴射する微細気泡生成ノズル１０と、導出菅６の分岐位置に設けられ、高圧スプレーノズル９又は微細気泡生成ノズル１０の何れか一方から洗浄水を噴射するよう流路を切り換える弁１１とを備える洗浄装置による。【選択図】図１
