HAND WASHING DEVICE
To provide a hand washing device equipped with an ejector-type mixing nozzle, that is equipped with a means for preventing solidification of a washing liquid in a washing-liquid supply path.SOLUTION: A hand washing device 1 comprises: a first on-off valve 121 provided in a water supply path 12; a second on-off valve 131 provided in a washing liquid supply path 13; a third on-off valve 141 provided in a branch supply path connecting the downstream of the first on-off valve 121 and the downstream of the second on-off valve 131; and a control part 3 that opens and closes the first on-off valve 121, the second on-off valve 131 and the third on-off valve 141, wherein the control part 3 closes the second on-off valve 131 after discharging washing foam from a mixing nozzle 11, water is supplied from the water supply path 12 to the mixing nozzle 11 by opening the first on-off valve 121 and the third on-off valve 141, a washing liquid remaining in the washing liquid supply path 13 is washed away by sucking the water from the washing liquid supply path 13 through the branch supply path 14 and air from an air intake port 111 into the mixing nozzle 11, and the water is discharged from the mixing nozzle 11.SELECTED DRAWING: Figure 9
【課題】エジェクタ形式の混合ノズルを備えた手洗い装置の洗浄液供給路における洗浄液固化防止手段を付加する。【解決手段】水供給路12に第１開閉弁121を、洗浄液供給路13に第２開閉弁131を、第１開閉弁121下流と第２開閉弁131下流とを結ぶ分岐供給路に第３開閉弁141を設け、第１開閉弁121、第２開閉弁131、第３開閉弁141を開閉させる制御部３を備えてなり、混合ノズル11から洗浄泡を吐出させた後、制御部３が第２開閉弁131を閉じ、第１開閉弁121及び第３開閉弁141を開くことにより、水供給路12から水を混合ノズル11に供給し、分岐供給路14を通じて洗浄液供給路13から水を、空気吸入口111から空気を混合ノズル11に吸引させて、洗浄液供給路13に残存する洗浄液を押し流し、混合ノズル11から水を吐出させることを特徴とする手洗い装置１である。【選択図】図９
