Abstract
This invention relates to a cooking device which cooks food evenly without making the food get out of shape, and also keeps the cooked food hot. The device has a hot water tank having a bottom inner tank provided in the bottom thereof and a bottom outer tank for surrounding the bottom inner tank through a flue. A combustion chamber is provided under the hot water tank. A guide partition plate is arranged at a gradient in the hot water tank and has a passage for passing hot water upward to its upstream side. A circulating unit is formed at a downstream side. A partition unit collects the hot water rising from the bottom of the hot water tank to guide the hot water to the passage side. A partition plate has a through hole and is provided to partition the hot water tank above the guide partition plate into a boiling chamber, located above the passage, and a heat insulation chamber, located above the partition unit.
