  • Patent number: 10526775
    Abstract: A toilet according to an embodiment includes a toilet body and a water drainage socket. The toilet body has a water drainage outlet on a back surface thereof. The water drainage socket connects the water drainage outlet and an inlet of a water drainage pipe that is provided on a wall surface. The back surface of the toilet body is provided with an opening and a guide part. The opening is provided to insert therethrough a tubular member that extends from the wall surface in a case where the toilet body is mounted on the wall surface. The guide part guides the tubular member that is provided in a state where it is inserted through the opening so as to move to an outer side of the water drainage socket in a case where the toilet body is mounted on the wall surface.

  • Patent number: 10428507
    Abstract: A flush toilet according to an embodiment includes a main water guide channel, a bending water guide channel, a rim water guide channel, and a retention part. The bending water guide channel bends a flow direction of washing water supplied from the main water guide channel. The rim water guide channel causes the washing water to flow toward and to be spouted from a water spout part. The retention part is formed in at least the bending water guide channel. An upper part of the retention part is formed into an opened concave shape and the retention part retains a part of the washing water. Furthermore, the retention part is formed in such a manner that an upper end thereof on a downstream side is horizontal to a bottom surface of the water spout part or higher than the bottom surface of the water spout part.

  • Patent number: 10344464
    Abstract: The present invention is a flush toilet (1) including: a bowl portion (8) having a bowl-shaped waste receiving surface (16), a rim portion (18), and a well portion (20) formed at the bottom of the waste receiving surface; a discharge trap pipe (12) connected to the bottom portion of the well portion; a flush water guide portion (40b) disposed on the waste receiving surface at the rear of the well portion so that flush water is directed toward the side wall surface inside the well portion; and a liquid membrane spouting portion (24) disposed on the rim portion, wherein this liquid membrane spouting portion induces a vertical circulating flow in the well portion, produced when discharged flush water assumes a liquid membrane form and collides with a flush water guide portion, and the colliding flush water drops along the side wall surface of the well portion.

  • Patent number: 10323400
    Abstract: A wash-out type toilet according to an embodiment includes a bowl that receives waste and a drainage water trap. The drainage water trap includes an inlet that is connected to a lower part of the bowl, a rise pipeline that is connected to the inlet and extends upward toward its own top part, a fall pipeline that extends downward toward an inlet of a drainage water pipe that is arranged on a floor surface, and an intermediate pipeline with an upstream-side portion that is connected to the rise pipeline and a downstream-side portion that is connected to the fall pipeline. Furthermore, the intermediate pipeline includes a retention surface that is formed to slope downward from an upstream side to a downstream side and temporarily retains waste at a time of toilet washing.
