When the cleaning water on / off valve 42 is opened, the cleaning water is discharged from the downstream end of the cleaning water flow path 41 to the bowl portion 6, and on the other hand, when the cleaning water on / off valve 42 is closed, Water discharge from the end of the washing water channel 41 is stopped.

  The cleaning water discharge port 43 at the downstream end of the cleaning water passage 41 is provided to face forward from the one side end of the rear part of the bowl part 6 along the upper part of the inner side surface of the bowl part 6. The washing water discharged into the section 6 is swirled.

  The washing water discharge device 4 is provided with fine bubble generating means 44 as shown in FIG. 7 that mixes air into the washing water, subdivides the air to generate fine bubbles, and includes the fine bubbles in the washing water. ing. The washing water mixed with fine bubbles has a water-saving effect due to a decrease in bulk specific gravity, a noise reduction effect due to friction reduction when the washing water collides with the inner surface of the bowl portion 6, and an effect of preventing water splashing. Thus, there is a bubble cleaning effect that strongly removes and adsorbs dirt adhering to the inner wall of the bowl portion 6 due to shock waves generated when the fine bubbles collide with the inner wall of the bowl portion 6 and ruptures or adsorption characteristics of the bubble interface.

  As shown in FIG. 7, the fine bubble generating means 44 is configured by a pipe portion in which an air mixing portion 45 is provided in the washing water flow path 41 and a venturi-shaped pressure sudden change portion 48 is provided downstream thereof. Yes. The air mixing part 45 is configured by connecting an air supply pipe 47 having a check valve around the downstream side of the nozzle part 46 whose diameter of the washing water flow path 41 is reduced. Due to the negative pressure generated by the discharge of air, air is mixed and air from the air supply pipe 47 is mixed into the cleaning water.

  The sudden pressure change portion 48 includes, in order from the upstream side, a reduced diameter portion 481 whose diameter is gradually reduced, a throat portion 482 having a reduced diameter, and an enlarged diameter portion 483 where the diameter gradually increases. It has an established structure. When the cleaning water flows through the sudden pressure change portion 48, the air mixed from the air mixing portion 45 is first expanded due to a decrease in the internal pressure at the reduced diameter portion 481 and the throat portion 482, and then the internal pressure at the expanded diameter portion 483. Ascending, shear force and shock waves act to break up and refine. In addition, as the fine bubble generating means 44, it is also possible to use a type in which the mixed air is dissolved in the cleaning water and then precipitated.

  As shown in FIG. 6, the detergent supply means 8 includes a detergent tank 81, a detergent supply path 82 that connects the detergent tank 81 and the detergent mixing unit 85 provided in the washing water flow path 41, and the detergent supply path 82. A detergent pump 83 and a detergent opening / closing valve 84 are provided.

  The detergent tank 81 is detachably held by a tank holder 9 fixed to one side (right side) of the trap case 71 as shown in FIG. 8, and contains detergent therein. The details of the detergent tank 81 will be described later.

  As shown in FIG. 6, the detergent supply path 82 branches from the middle of the circulation path section 820 and the circulation path section 820 in which the start end of the forward path section 821 and the end section of the return path section 822 are connected to the detergent tank 81. And a supply path part 823 that reaches the detergent mixing part 85 in the circulating water flow path. The detergent pump 83 is provided in the circulation path part 820 (in this embodiment, the forward path part 821 of the circulation path part 820). The detergent opening / closing valve 84 is provided on the downstream side of the supply path portion 823.

  When the detergent pump 83 is driven, the liquid detergent stored in the detergent tank 81 circulates in the circulation path portion 820. This prevents the detergent from clogging due to solidification or the like in the detergent supply path 82.

  The detergent mixing unit 85 is a part that generates a negative pressure in the wash water that flows by narrowing the flow path diameter of the wash water flow path 41. In the present embodiment, the throat part 482 is the detergent mixing unit 85.

  The detergent opening / closing valve 84 is opened when a negative pressure of the washing water is applied in the detergent mixing section 85 and the detergent pump 83 is driven and the pump pressure is applied. Mix in.

  The cleaning water containing bubbles mixed with the detergent is discharged into the bowl portion 6 from the cleaning water discharge port 43 at the downstream end of the cleaning water flow path 41 and becomes a swirling flow and spreads over the inner surface of the bowl portion 6 thoroughly. In addition, the detergent that has been mixed allows the detergent cleaning effect to be exerted on the inner surface of the bowl portion 6 without any problem, thereby enabling effective cleaning. Further, since detergent (surfactant) is mixed in the washing water to reduce the surface tension of the water, the diameter of the fine bubbles generated by the fine bubble generating means 44 can be reduced from the order of mm to the order of μm. Here, the fine bubbles of the order of μm have properties that are much harder to break than the fine bubbles of the order of mm. For this reason, the cleaning water remains in the bowl portion 6 as the accumulated water after the bowl portion 6 is washed, but at this time, fine bubbles can remain for a long period of time, preventing the adhesion of dirt near the water line of the accumulated water. It is designed to be effective.

  Hereinafter, the detergent tank 81 and the configuration around it will be described in detail.

  As shown in FIG. 8, the starting end portion of the forward path portion 821 and the terminal end portion of the forward path portion 821 in the detergent supply path 82 are configured by cylindrical connecting portions 31 and 32, respectively.
