A counter flow heated-air generator is provided to flow and emit a combustion heat source from bottom to top, and counter-flow outer air from top to bottom to quickly supply the heated-air. A counter flow heated-air generator includes an outer casing(4), a combustion room(5), a heat collecting room(8), a flue(9), a heated-air chamber(10), a blast fan(11), a plurality of induced partitioning plates(12), a heated-air exhaust port(14), heat exchanging pipes(15), and an exhaust port(17). The outer casing is formed inside of a frame. The combustion room is formed inside the outer casing and connected to a burner(6). The heat collecting room is communicated by a plurality of heat exchanging pipes(7) to flow a heat source to an upper portion of the combustion room. The flue is communicated with an upper portion of the heat collecting room. The heated-air chamber is formed between the outer casing, the combustion room, and the upper portion of the heat collecting room. The blast fan is formed at a side of the heated-air chamber. The plurality of induced partitioning plates are installed on the heat exchanging pipe, and include an air space for inducing air supply to the heated-air chamber. The heated-air exhaust port is formed to exhaust the heated-air through an isolation plate installed vertically inside of the outer casing. The heat exchanging pipe is communicated with the heated-air chamber. The exhaust port includes a plurality of vent holes formed to flow the air to the lower portion of the combustion room in zigzags.
