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.
