The invention discloses a rapid-flushing type integrated elbow floor drain, which comprises a diversion block, wherein two liquid passages, which are image-symmetrical, are formed in the diversion block; liquid inlets of the liquid passages extend to the upper surface of the diversion block and liquid outlets of the liquid passages are connected to the bottom of the diversion block; a stream guidance pipe is arranged between the liquid outlets of the two liquid passages; two ends of the stream guidance pipe are butted with the liquid outlets of the two liquid passages; the side faces, away from the sidewalls of the diversion block, of the stream guidance pipe are provided with discharging ports; the liquid passages are three-dimensional pipes provided with horizontal bends and vertical bends; the liquid passages are composed of liquid inlet pipes, blocking elbows, transition pipes and blocking liquid outlet pipes which are sequentially connected; and the liquid inlet pipes and the transition pipes are mutually staggered in a vertical plane. Through opposite flushing caused by a floating wall flow generated on the stream guidance pipe, a cleaning step can be greatly simplified; with the design of a square opening, the loss rate of a water flow is reduced; and the elbow floor drain not only guarantees a drainage efficiency but also guarantees a flushing function.
