The invention relates to a rapid energy-saving steamer which comprises an inner heating body, an inner heat conductor, a steam heat insulation plate, a steamer cove and an outer insulation body, wherein the inner heat conductor consists of three layers of inverted U-shaped stainless steel; a gap is formed between a first-layer heat conductor and a second-layer heat conductor, so as for form a clear water layer; a gap is formed between the second-layer heat conductor and a third-layer heat conductor, a bottom plate of the gap is provided with a vent hole; the bottom of the side wall of the second-layer heat conductor is provided with a water-adsorbing hole; the second-layer heat conductor and the top of the third-layer heat conductor are fused into one layer; the steamer cover is arranged at the top of the outer insulation body; the inner heating body is fixedly arranged in the outer insulation body; the inverted U-shaped inner heat conductor covers the exterior of the inner heating body; the steam heat insulation plate is fixedly arranged in the outer insulation body and on the inner heat conductor. The rapid energy-saving steamer achieves the purpose of quick cooking, and can be used for solving the problems that existing food steam boiling speed is slow and disposable water can not be recycled, so that the speed of the steamer is improved, the effects of low consumption and rapid heating speed are achieved.
