摘要：
A vortex fountain or waterer that incorporates measures to induce swirl in liquid moving toward a drain opening of the fountain to inhibit the accumulation of debris is provided. The fountain may have a bowl including a base surface having a slope that is configured to create a vortex in the liquid flowing toward the drain opening to induce movement of a quantity of water, where the bowl is located above a basin configured to hold the liquid. The fountain may also include a pump outlet jet that can be positioned about the bowl to induce swirl about the bowl. The fountain may also include a drain tube located beneath the drain opening, and an extended guide tube extending downwardly towards the bottom of the basin. When the liquid passes through the drain, drain tube, and guide tube, oxygen is incorporated into the liquid as the liquid reaches the basin.
