PROBLEM TO BE SOLVED: To provide an inexpensive washing device having a function of preventing liquid drip from a nozzle.SOLUTION: A washing device 1 of the present invention comprises a storage tank 30 capable of storing liquid, a pump P for adding air to the liquid to generate mixed liquid, a melting tank 20 for storing the mixed liquid while keeping it under a predetermined pressure, a nozzle 10 for generating and discharging microbubble cleaning liquid by passing the mixed liquid of the melting tank 20 therethrough, and a piping passage for circulating the microbubble cleaning liquid. The piping passage is formed of a storage passage 9 for feeding the liquid to the melting tank 20 from the storage tank 30, a nozzle feeding passage 8 for feeding the mixed liquid in the melting tank 20 to the nozzle 10, and a discharge passage 5 for discharging high pressure gas in the melting tank 20 to outside. The nozzle feeding passage 8 forms a passing passage for the mixed liquid subject to the internal pressure of the melting tank 20. The discharge passage 5 forms a passage of the high pressure gas in the melting tank 20, and comprises a solenoid valve 6 for switching between passage and blockage of the high pressure gas.SELECTED DRAWING: Figure 1 【課題】ノズルからの液垂れ防止機能を具備した低コストの洗浄装置の提供。【解決手段】本発明の洗浄装置１は、液体を貯留可能な貯留槽３０と、前記液体に気体を含んだ混合液へ生成するポンプＰと、前記混合液を所定の圧力に保ち貯留する溶解タンク２０と、溶解タンク２０の混合液を通過させてマイクロバブル洗浄液を生成し排出するノズル１０と、前記マイクロバブル洗浄液を循環する配管経路とを備える。前記配管経路は、貯留槽３０から溶解タンク２０へ液体等を給送する貯留経路９と、溶解タンク２０内の混合液をノズル１０へ給送するノズル給送経路８と、溶解タンク２０内の高圧気体を外部へ排出する排出経路５とから構成される。ノズル給送経路８は、溶解タンク２０の内部圧力を受ける混合液の通過経路を成す。排出経路５は、溶解タンク２０内の高圧気体の通過経路を成し、前記高圧気体の通過あるいは遮断を切り替える電磁弁６を備える。【選択図】図１
