The gaps 28, 29, 30 on the side surface side of the rice cooker 2 are narrower than the gap 25 on the bottom side of the rice cooker 2 so that hot air stagnates and fills in the gap 25. In particular, the upper end portion of the gap 29 located above the rice and water introduced into the rice cooker 2 is made the narrowest so that heat spreads to the rice and water.

  In this state, when a mixed gas of fuel gas and air is supplied from the supply pipe 51 of the gas supply means 24 to the first chamber 31 of the heating means 23, the mixed gas supplied to the first chamber 31 is In the first chamber 31, the fuel gas and air are stirred in a vortex shape while being swirled and circulated along the inner surface of the outer wall portion 42, and the fuel gas and air are sufficiently mixed by this stirring to homogenize the mixed gas.

  Since the mixed gas is successively supplied from the supply pipe 51 to the first chamber 31, the mixed gas homogenized by stirring is brought closer to the inner wall portion 41 side, and an annular opening near the upper end portion 41 a of the inner wall portion 41. It is supplied to the second chamber 34 through the section 33.

  When the homogenized mixed gas is supplied to the second chamber 34 from the annular opening 33, the homogenized mixed gas is diffused throughout the second chamber 34 and is filled in the second chamber 34. After that, it flows into the large hole portion 81 from the small hole portion 82 of the surface combustion member 71 and burns at the combustion surface portion 72 by ignition by a spark rod or the like (not shown).

Since the gas once enters the large hole portion 81 having a large opening diameter from the small hole portion 82 and diffuses and then flows to the combustion surface portion 72, the mixed gas is uniformly distributed throughout the combustion surface portion 72. It will burn. And the surface combustion member 71 is disperse | distributed and arrange | positioned to the whole upper surface of the bottom-plate opposing part 26, The bottom-plate part 5 of the rice cooking pot 2 can be heated more uniformly over the whole, and the rice in the rice cooking pot 2 is made more. Can be cooked uniformly.

  Further, the mixed gas supplied from the gas supply means 24 to the first chamber 31 is stirred while rotating in the first chamber 31 and then supplied from the annular opening 33 to the second chamber 34. The mixed gas that is sufficiently mixed with air and homogenized can be supplied to the second chamber 34. As a result, the bottom plate portion 5 of the rice cooker 2 can be heated uniformly throughout the rice cooker 2, and the rice in the rice cooker 2 can be more evenly distributed. Can be cooked.

  For example, the outer peripheral surface of the large diameter portion 75 of the main body 73 may be formed in a polygonal cylindrical surface shape such as a hexagon so that the surface combustion member 71 can be easily rotated by a tool such as a spanner. That is, the shape of the surface combustion member 71 is not limited to a cylindrical shape, and may be a polygonal cylindrical shape or the like.

  Further, the case where the surface combustion member 71 is detachably attached to all the mounting screw holes 68 and the whole surface is uniformly heated on the upper surface of the bottom plate facing portion 26 has been described.For example, for adjusting the heating force, A desired number of surface burning members 71 are removed from the mounting screw hole 68, and instead, a stopcock (mekura) having a male screw is attached to the mounting screw hole 68 to intentionally form the upper surface of the bottom plate facing portion 26. You may make it heat by attaching the strength of heating power to.

  Further, for example, a configuration in which the surface combustion member 71 is detachably fitted to the mounting hole may be employed.
