A vortex flow type water surface control device for a draining device is provided. The vortex flow type water surface control device may include an inflow pipe, an outflow pipe, an intercepting pipe, and a separating weir that is disposed to block the intercepting pipe and the inflow pipe from the outflow pipe. The vortex flow type water surface control device may also include a control plate that is disposed between an opening of the inflow pipe and an opening of the intercepting pipe. A height of the control plate may be higher than at least a height of the separating weir. The control plate may be apart from the separating weir, and may approximately extend to a center axis of the intercepting pipe.
