In this example, T ₉ = 3 seconds. Therefore, in this embodiment, when 4 hours 59 minutes 57 seconds (or 6 hours 59 minutes 57 seconds, 8 hours 59 minutes 57 seconds) have elapsed from the start of the operation, the drive mechanism 13 is driven for 3 seconds to 5 rotates.

T ₅ = (T ₁ + T ₂ ) × N ₂ = (T ₃ + T ₄ ) × N ₂ , T ₆ = (T ₁ + T ₂ ) × 2 × N ₂ = (T ₃ + T ₄ ) × 2 × N ₂ , T ₇ = (T ₁ + T ₂ ) × 3 × N ₂ = (T ₃ + T ₄ ) × 3 × N ₂ . However, _{N 2} is a natural number of 2 or more. That is, the rice body 5, the N ₂ nd power distribution end of the evaporation heater 77, and rotates N ₂ nd driving Simultaneously with the completion of the pump 71.

  Further, since the concave surface 53 provided between the protrusions 51 and 51 is inclined from the top to the bottom toward the inner surface from the outer surface side of the heel receiver 3, the heel is accumulated on the concave surface 53. It is difficult, and even if it accumulates, it can be easily removed.

  In addition, since the heat transfer section 26 is composed of a plurality (two) of thermally conductive metal plates 27 and 27, it can be manufactured at a lower cost than when a single metal plate is used.

  Furthermore, the interior member 10 is provided inside the storage recess forming portion 7B, the interior member 10 is formed of a heat conductive metal plate or the like, and the linear heater 12 is disposed on the outer surface of the interior member 10. The heat of the heater 12 can be efficiently transferred to the rice milling container 4. Moreover, since the heat insulation space 11 by the air layer is provided around the interior member 10, the heat of the linear heater 12 can be prevented from escaping to the outside.

  In addition, this invention is not limited to the above Example, A various deformation | transformation implementation is possible within the range of the summary of invention. For example, in the above embodiment, as the positioning portion, two concave portions are provided on the lid body and two convex portions are provided on the rice mill body, but the convex portion may be provided on the lid body and the concave portion may be provided on the rice miller body. The number may be one or three or more. Moreover, in Claim 1, the position of the water tank provided in a rice mill main body is not limited. Furthermore, the dew receiving part may be provided integrally with the inner lid. In this case, the dew receiving part may be formed integrally with the inner cover. Moreover, although the said Example demonstrated the cover body opened and closed by a hinge as an example, it is applicable also to a detachable cover body. Moreover, in the said Example, although the linear heater was used for the heater, it is not limited to this, You may use a planar heater etc. Furthermore, in the said Example, although the heater was provided in the outer periphery of the side part 10A of the interior member 10, you may provide a heater in the inner periphery of the side part 10A, and even if it provides in the bottom face part 10B of the interior member 10. Good. Moreover, in the said Example, although the two metal plates were used for the conduction | electrical_connection part, 1 sheet or 3 sheets or more may be sufficient. Furthermore, in the said Example, although the container lower part 25 of the soot receptacle 3 was formed with the synthetic resin, it is good also considering the container lower part as a heat-transfer part with a heat conductive metal.
