Abstract: 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.

Abstract: A toilet 10 has a bowl 20, a connection pathway 31, an ascending pathway 32, and a descending pathway 33 across a weir 34. The descending pathway 33 includes an expanded section 33a having a greater pipeline diameter and a tapered end 33b having a narrower opening area than that of the expanded section 33a, and is connected with a drain socket 70. The drain socket 70 has an inner drain conduit socket member 72 that is attached to be located inside a drain conduit 90. The inner drain conduit socket member 72 has an extended socket section 75, which is located below a floor surface FL of a lavatory and has a greater pipeline diameter, and a tapered conduit section 76, which has a narrowed diameter. These sections 75 and 76 constitute a siphon action induction module.

Abstract: When a cleaning button for cleaning the toilet bowl is operated, by a manner as pressing, a switching valve 41 switches the flushing water supply destination to a position for cleaning the bowl part. The flushing water is then jetted out of a spout nozzle 35 disposed inside a Z water conduit 161 as a jet flow. The jet flow from the spout nozzle 35 causes water inside the Z water conduit 161 and water inside the flushing water reservoir 104 to flow through the Z water conduit 161 and to be spouted toward an inlet 121 of a waste trap 102, like a jet flow spouted by a jet pump. This supplies a heavy flow of flushing water amplified in the volume into the waste trap 102 all at once to flush out the filth in the bowl part 101.

Abstract: A non-membrane type electrolytic cell (10) comprises an anode plate (16, 20) and a cathode plate (18) which are arranged opposite to each other with an electrically insulating spacer (22) sandwiched therebetween. The spacer (22) is formed of plastics having a water absorption of not more than 0.3%, preferably not more than 0.2%, more preferably not more than 0.01%. Deposition of scale, such as calcium carbonate, on the spacer (22) is prevented.

Abstract: A strong acid sterilizing liquid containing hypochlorous acid at a low concentration consists of electrolyzed salt water, wherein the pH of the liquid is 3 or less and the concentration of the hypochlorous acid is 0.2 ppm to 2 ppm.

Abstract: 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.
