A jetted bathtub includes: a bathtub; a suction port opening in a wall of the bathtub and allowing water stored in the bathtub to be sucked therein; a pressurizer configured to suck water from the suction port, and pressurize and discharge the water; and a jet nozzle having a single tube held on the wall below a rim of the bathtub, the jet nozzle being configured to eject water introduced into the tube so that the water is ejected into the bathtub with its ejection direction being varied. The tube includes: a running water introduction section configured to receive water supplied from the pressurizer; a channel cross-section shrinking section communicating with the running water introduction section on the downstream side of the running water introduction section, and having a reduced channel cross section relative to the running water introduction section; and a chamber communicating with the channel cross-section shrinking section on the downstream side of the channel cross-section shrinking section, and having at its upstream end a channel cross-section abrupt expansion section with a channel cross section abruptly expanded relative to the channel cross-section shrinking section and at its downstream end an ejection port facing the inside of the bathtub.

Non-membrane electrolytic cell for electrolysis of water

Strong acid sterilizing liquid containing hypochlorous acid at a low

A water electrolyzer for electrolyzing water to produce and recover acidic and/or alkaline water. The electrolyzer is of the membraneless laminar-flow type which is designed to electrolyze water without placing a membrane between the electrodes. To this end, the anode and cathode are arranged closely with one another with a very small spacing (generally less than 1 mm) to establish a laminar flow in a narrow flow path. The anode is provided with a slit-shaped aperture for separating a thin layer of acidic water flowing along the anode surface. This aperture is situated sufficiently upstream of the downstream end of the flow path to ensure that the layer of acidic water is separated away from the remainder of the laminar flow while the laminar flow is sustained in the flow path. Accordingly, formation of turbulence at a point of acidic water separation is minimized so that highly acidic water can be recovered.
