  • Publication number: 20130227773
    Abstract: The present invention relates to a toilet bowl including a rotary discharge pipe. A toilet bowl according to the present invention includes: a bowl on which a user sits; an outlet disposed behind the bowl; a discharge guide pipe communicating with the outlet, and connecting to a pipe embedded in a floor to discharge water; and a rotary discharge pipe having a discharge hole in the top thereof, and an inflow hole in an end thereof. According to the present invention, both the restoring force generated from a balancing structure of the rotary discharge pipe and torque generated from the kinetic energy of water (wastewater) discharged from the bowl are used to operate the rotary discharge pipe, thereby reducing the possibility of malfunction. In addition, since the toilet bowl has a simple structure, the manufacturing cost thereof can be decreased.

  • Patent number: 8516623
    Abstract: Tilting Bowl Toilet comprises a frame, a toilet basin, and a tilting bowl. The tilting bowl is supported below the toilet basin to receive and hold water/waste delivered from the toilet basin. The tilting bowl tilts to discharge its content to drainage. The tilting bowl at standby is sustained to stay in a horizontal position by a sustaining turning moment about its support axis. When water is added, the turning moment produced by the tilting bowl with its content becomes larger than the sustaining turning moment, and the tilting bowl moves to a tilted position to discharge its content. As the tilting bowl tilts, the sustaining turning moment is simultaneously reduced to accelerate bowl tilting for efficient discharge of waste to sewage.
