If it does in this way, the power supply cord 27 of the wound state will be reliably hidden in the bottom part of the rice cooker main body 1, and it will further improve appearance.

  Further, the distance D1 (see FIG. 3) between the protrusion 26 and the bottom surface of the rice cooker body 1 is larger than the thickness d of one power cord 27 and smaller than the thickness of two. That is, the power cord 27 cannot be wound twice above the protrusion 26 in the auxiliary support leg 25.

  Further, the distance D2 (see FIG. 3) from the tip of the auxiliary support leg 25 (that is, the ground contact surface) to the upper surface of the protrusion 26 is made larger than the thickness d of one power cord 27. In this way, even if the power cord 27 that is not wound around the protrusion 26 of the auxiliary support leg 25 is wound around the lower side of the protrusion 26 of the auxiliary support leg 25, the power cord 27 may rub against the table. The power cord 27 can be prevented from being damaged.

  Furthermore, the outer wall shape of the bottom member 1b is tapered so as to exhibit a function of guiding when the power cord 27 is wound. And the outer peripheral end of the said protrusion 26 is positioned inside the line S which extended the outer wall shape of the bottom member 1b. If it does in this way, the power cord 27 wound around the protrusion 26 and the auxiliary support leg 25 will not be visible from the outside, and the appearance will be improved.

Incidentally, in FIG. 4 shows another winding state of the power cord 27, as wrapped around the two auxiliary support legs 25 and 25 after winding round the four auxiliary support legs 25, 25, 25, 25 I have to. In some cases, the four auxiliary support legs 25, 25, 25, 25 are wound once and then wound around the three auxiliary support legs 25, 25, 25. In this case, a part of the power cord 27 is wound around the diagonal auxiliary support legs 25, 25. In this case, the water reservoir 21 formed at the center of the bottom member 1b is connected to the power cord. A part (namely, diagonal part) of 27 will be supported.

In the present embodiment, the power cord 27 is wound only around the auxiliary support legs 25, 25, 25, 25, but the main support legs 23, 23, 23 and the auxiliary support legs 25, 25, 25, 25 Of these , the power cord 27 may be wound around all or part of at least a plurality of auxiliary support legs .
