A steam case includes a case body having an inner portion provided with a receiving chamber which has a bottom provided with a water tank. The case body has a lower portion provided with a receiving space located under the water tank to receive a burner. The case body is provided with an inner water storage conduit, an outer water storage conduit and an air draining channel located between the inner water storage conduit and the outer water storage conduit. Thus, the waste air produced by the burner during the heating process is kept at a higher temperature and can be reused to heat the water in the inner water storage conduit and the outer water storage conduit and to increase the temperature of the water in the water tank so as to shorten the heating time of the steam case.
