  • Patent number: 10407888
    Abstract: The bidet system may include multiple seat scales which may float between the toilet bowl rim and the toilet seat. These seat scales may collect measurements which are transmitted to a controller. The controller may include instructions to calculate a user's center of mass based on the measurements and to identify the position of the user's anus based on the center of mass. The controller may then transmit instructions to a bidet wand directing direct the bidet wand to a position which aims a cleansing fluid spray toward the user's anus. A camera which collects images of the user's anal and urogenital region may also be included in the bidet system. The camera may transmit obfuscated images to the controller to identify other areas of the user's anatomy in need of cleansing. The controller may direct the bidet wand to aim a cleansing fluid spray toward these areas.

    Abstract: This invention comprises a bidet device, including a bidet kit, that can be mounted on a conventional toilet seat. A bidet valve is positioned between a bidet hoop conduit and a water supply conduit. Rotation of the bidet hoop conduit results in rotation of a valve seat relative to a valve stem to permit water to flow through the bidet hoop conduit. Water does not initially flow and only flows as the bidet hoop conduit reaches an extended operative position. Rotation of a handle or lever arm is the only movement necessary to move the bidet hoop conduit and initiate actuation of the valve. The bidet valve includes an actuator with a notch, the sides of which engage a stationary arm attached to the toilet seat to open and close the valve.

  • Patent number: 7913329
    Abstract: An anal cleaning device (1) includes a fluid flow directing member (2) connectable to a fluid source (14). The member (2) has a fluid outlet 10a for directing fluid from the source out of the member. A wall member (11) projects out from the flow directing member (2) near the fluid outlet (10a). The wall member (11) is positionable at a perineum of a user such that, when located thereat, the wall member (11) spaces the fluid outlet (10) a from the user's anus and tends to prevent fluid from reaching that side of the wall member (11) opposite to the fluid outlet (10) a side of the wall member (11). The flow directing member (2) is optionally a detachable cleaning head (10). The wall member (11) can be formed integrally with the head (10) to project orthogonally therefrom and intermediate a first head end (10b) connectable to a fluid source line (12) and a second opposite head end (10c) near which the fluid outlet (10a) is located.

  • Patent number: 7886373
    Abstract: Provided is a method of controlling temperature of warm water of a bidet. The method includes: a first step of detecting a current temperature of warm water stored in a storage tank; a second step of gradually adjusting intensity of power supplied to a heating means depending on a difference when the current temperature of the warm water is lower than a target temperature; and a third step of cutting the power supplied to the heating means when the current temperature of the warm water is equal to the target temperature after the second step. Therefore, the warm water can be precisely maintained at a set temperature by checking a temperature of cleaning water in a storage tank using a sensor in real time, and gradually controlling intensity of power supplied to a heating means on the basis of the checked water temperature.
