A rotary type double-layer electric sickbed comprises an upper frame, a seat plate is installed at the top of the upper frame, a turnover backrest assembly is installed at one end of the seat plate, a knee supporting assembly capable of being rotatably folded is installed at the other end of the seat plate, a lower frame is rotatably connected to the center of the bottom face of the upper frame, and a rotation driving assembly is installed in the lower frame and used for driving the upper frame to rotate by 90 degrees. The backrest assembly can turn over up and down, so that a lying patient can be supported to sit up, the knee supporting assembly can drive the legs of the patient to be in a bent state, the legs and the waist of the patient can be moved, and meanwhile, the backrest assembly and the knee supporting assembly can retract, and the upper frame can rotate subsequently; and the rotating driving assembly can drive the upper frame to rotate by 90 degrees, then the upper frame and the lower frame are matched to form a cross state, in this way, a patient can get out of the bed conveniently, and the flexibility of the sickbed is higher.
