摘要： PROBLEM TO BE SOLVED: To improve a function in the case that the washing water is ejected along the inside wall face of the upper edge of the bowl 20 to wash the bowl. SOLUTION: A shelf part 50 is formed at the upper end of the exposed face 24 of the bowl 20 in a toilet stool 10 and an overhanging part 52 rising from the shelf part is formed of a rim 21 surrounding the bowl 20. The shelf part 50 is formed of a circular passage circulating around the bowl. Rimshot washing water RS is flushed to the downstrem of the passage along the shelf face. In the rim 21, the overhanging state of the overhang part 52 from the shelf part 50 is made different along the circular passage of the shelf 50. The overhang part 52 is overhung so as to be arranged opposite to the shelf part 50 in the vicinity of the spout 44 of the rim to avoid the dispersing ejection of the rimshot washing water RS. In other regions, the overhang part is slanted against the shelf 50 to prevent the washing water from scattering out of the toilet stool.

摘要： PROBLEM TO BE SOLVED: To improve cleaning performances in the case that rim is washed together with the bowl. SOLUTION: The toilet stool 10 has two spouting systems of washing water. One spouting system (jet spouting system) has a path from a flushing water supply hole 40 which is a flushing water inlet from a flushing water tank 310 to a jet spouting aperture 22 opened to the recess 26 of the bowl bottom. The other spouting system (rim shot spouting system) has a passage from the flushing water supply hole 40 to a rim spouting aperture 44 opened on the upper side face of the bowl 20. The jet spouting system and the rim shot spouting system are divided into the upper inflow part 41a and lower inflow part 41b by a diversion partition wall 41c in the vicinity right under the flushing water supply hole 40, and flushing water is divergently supplied into respective spouting apertures from the first.

摘要： PROBLEM TO BE SOLVED: To surely clean the surface of a bowl part and discharge filth by a very small amount of flush water in a siphon jet toilet tool. SOLUTION: As a passage of water from a washing tank 310, a conduit S1 constituted by a flushing water feed hole 40, a flushing water introducing passage 41, a diverging hole 42, a jet conduit 46, a jet hole 22, a rim conduit 43 and a water emitting hole 44 is formed in the interior of this siphon jet toilet stool 10. When flushing water from the flushing tank 310 having a tank actual volume of 4 l in large flushing and a tank actual volume of 3 l in small flushing is supplied through the flushing water feed hole 40 to the flushing water introducing passage 41, the flushing water is favorably distributed to the jet water introducing passage 46 and the rim water introducing passage 43 by the diverging hole 42. As a result, flushing water sufficient to cause a siphon action early and continuously is jetted from the jet hole 22, and flushing water sufficient to wash the surface of the bowl part 20 is discharged from the water emitting hole 44.

摘要： PROBLEM TO BE SOLVED: To cause stable siphon action by small amount of water in a siphon type flush toilet stool. SOLUTION: A section from the vicinity of a start end of a connection passage 31 which is a water drain passage for soil and soil water of a stool 10 to a terminal end of a rising passage 32 is formed in such a way that it has substantially same cross sectional area. Consequently, washing water is not accelerated due to a difference of flow passage area when washing of the stool 10 is started and washing water flows from a discharge port 25 toward a top part of the rising passage 32. As a result, pressure loss of washing water is reduced when compared with the case where it is accelerated. Moreover, flow directions of washing water are not overlapped in mutual washing waters to prevent the occurrence of turbulent flow in a flow passage due to gradual reduction of a thickness of the flow passage. Soil OB moves smoothly up to the terminal end of the rising passage 32 in accordance with the flow direction of washing water and is led into a lowering passage 33.

摘要： PROBLEM TO BE SOLVED: To provide a small apparatus for generating and spraying a strongly acidic germicidal water with low-concentration hypochlorous acid, capable of being readily carried and having ensured sterilizing power of ejected water. SOLUTION: This spraying apparatus has a membrane-less type electrolytic cell 31, a saline solution tank 35, a means for sending a saline solution from a discharged water- collecting tank 36 and 35 to an electrolytic cell 31 by pressure, a spraying device 32, a direct current electric power unit 38, and a controller 39. The electrolytic cell 31 has a water-flow path formed without the membrane by a couple of smooth walls facing and approaching to each other in parallel, an anode plate forming at least a part of the wall at one side of the walls, a cathode plate forming at least a part of the other side, an acidic water- collecting flow path linked to the water flow path through the opening formed on the wall a part of which is formed by the anode plate in the downstream region of the water flow path, an alkaline water-collecting flow path linked to the downstream end of the water flow path, and a saline solution-supplying flow path linked to the upstream end of the water flow path. The saline solution-supplying flow path is lined to the collection tank 35. The alkaline water-collecting flow path is linked to the collection tank 36. The acidic water- collecting flow part is lined to the acidic water-discharging opening. The acidic water- discharging opening is connected to the spraying device 32. The spraying device 32 has a piezoelectric element and a perforated plate having one terminal fixed to the piezoelectric element.
