  • Patent number: 9267276
    Abstract: A water discharge device generates a large air bubble having a cross sectional area larger than a channel sectional area of a jetting port when the inside of a water storage chamber is viewed from the jetting port. The water discharge device intermittently forms the large air bubble to change a flow speed of a jet flow.
    Type: Grant

  • Publication number: 20110173744
    Abstract: A sanitary washing apparatus includes a washing nozzle configured to discharge wash water toward a human body part, the washing nozzle including: a water supply path configured to pass the wash water; an orifice configured to direct the wash water passed through the water supply path toward the human body part; a throat provided on a trajectory connecting the orifice and the human body part; a mixing chamber provided on a downstream side of the orifice and on an upstream side of the throat, an area of a cross section of the mixing chamber perpendicular to a discharge direction of the wash water being larger than an area of a cross section of the orifice perpendicular to the discharge direction; and an air intake portion configured to take air into the mixing chamber by a negative pressure generated by wash water flowing from the orifice toward the throat, a return flow being generated in the mixing chamber by wash water flowing out from the orifice and having a flow direction changed by a wall face of the mix
