In this fully open position, the inner lid 82 is held upward and tilted rearward by about 10 to 20 degrees with respect to the vertical. An extension 88A extending toward the center is provided on the inner edge 88 of the packing 85, which is the lower side in the fully opened position, and the extension 88A constitutes a dew receiving portion. Further, a shield part 89 is provided at the inner end edge of the extension part 88A, and the shield part 89 is formed in the vertical direction so as to lightly block between the extension part 88A and the lower surface of the inner lid 82.

  Therefore, when the lid body 6 is fully opened and water droplets adhering to the inner surface of the inner lid 82 are transferred to the inner surface and dropped, the water droplets can collect between the inner surface of the inner lid 82 and the extension portion 88A and leak to the outside. Absent. The upper edge of the shielding part 89 is in light contact with the inner surface of the inner lid 82, but there is a gap narrower than rice grains between the left and right edges of the shielding part 89 and the inner peripheral surface of the pressing part 82B. Water can pass through the gap. Further, since the upper edge of the shielding part 89 is not in close contact with the inner surface of the inner lid 82, water can pass between the upper edge of the shielding part 89 and the inner surface of the inner lid 82. is there. In this case, since the outer fitting portion 86 of the packing 85 is closely attached to the outer edge portion 82A of the inner lid 82, the accumulated water does not leak to the outer surface side of the inner lid 82.

  On the other hand, since the inside of the extension portion 88A is blocked by the shielding portion 89, rice in the milled rice can be prevented from entering the extension portion 88A.

  As shown in FIG. 12, an operation unit 121 is provided on the front upper surface 2A. The operation unit 121 is provided with an operation / stop switch 122, a normal rice milling switch 123, a GABA rice milling switch 124, an amount switch 125, and a finishing timer switch 126. By pressing the regular rice milling switch 123, the degree of milling in the “regular rice milling” mode can be selected from “3-minute sowing”, “5-minute sowing”, “seven-minute sowing”, “germ rice”, and “white rice”. Note that “3 minutes sowing” is also selected when re-milling old white rice. In addition, by pressing the GABA milled rice switch 124, a mode of making brown rice enriched with GABA (GABA brown rice), that is, "GABA" mode, and white rice enriched with GABA brown rice by milling GABA brown rice (GABA white rice) ), That is, the “GABA milled rice” mode can be selected. Further, by pressing the finishing timer switch 126, the finishing time of the GABA brown rice in the “GABA” mode or the finishing time of the GABA white rice in the “GABA milled rice” mode can be selected.

  In use, after the rice milling body 5 is attached to the secondary driven shaft 38 of the rice milling container 4, a predetermined amount of rice is accommodated in the rice milling container 4. Further, the rice bran receiver 3 is attached to the storage recess 7 </ b> A of the rice mill main body 2. At this time, the upper side of the primary connection portion 21 constituting the coupling 40 is exposed from the cylindrical portion 7D, and the outer peripheral side is covered by the cylindrical portion 25C. And the said rice milling container 4 in which the said rice milling body 5 was attached and the rice was accommodated is mounted | worn to the inner side of the said rice bran receptacle 3. At this time, the secondary connection part 39 constituting the coupling 40 is inserted into the cylindrical part 25C and engaged with the primary connection part 21, and the cylindrical part 25C is connected to the cylindrical part. It is mounted so as to cover the upper outer side of 35B with a slight gap. As a result, it is possible to prevent the rice cake separated from the brown rice by the milled rice and entering the rice cake acceptor 3 from leaking from the opening at the upper end of the cylindrical portion 25C. Moreover, the lower end inner surface of the cylindrical part 35B covers the upper end outer surface of the cylindrical part 7D with a slight gap. As a result, the rice milling container 4 is positioned with respect to the cylindrical portion 7D, that is, the rice milling machine body 2.

  Then, when the rice milling container 4 is mounted in the rice bran receptacle 3, the upper edge of the rice milling container 4 is disposed between the protrusions 51, 51 provided on the inner peripheral surface 24C of the rice bran part 24A of the rice bran receptor 3. When the engaging protrusion 54A of 36A is engaged, the milled rice container 4 is positioned in a non-rotating state with respect to the rice bran receptacle 3.

  Further, when the lid body 6 is closed, the start end connection portion 102 of the lid body 6 is connected to the terminal end connection portion 75 of the rice miller body 2. When the lid body 6 is closed, the pressing unit 84A of the lid body 6 pushes the lid open / close detection switch 78, so that a control means (not shown) detects that the lid body 6 is in a closed state. . In this case, the positioning concave portions 111 and 111 of the lid body 6 are engaged with the positioning convex portions 112 and 112 of the rice milling machine body 2 so that the front side of the lid body 6 is correctly positioned on the rice milling machine body 2. . The rice mill 1 is driven on condition that the lid 6 is closed, and is not driven when the lid 6 is open.

  In this way, after the upper opening of the storage recess 7A is closed by the lid body 6, when a power cord (not shown) is connected to an AC power source, the power is turned on.

  Then, the amount switch 125 is operated in accordance with the amount of brown rice to be polished, the normal rice switch 123 is operated to select the degree of rice polishing, and then the operation / stop switch 122 is operated. Thus, the electric motor 16 is driven via the drive circuit. Then, the rice milling body 5 is rotated by the drive mechanism 13, whereby the rice in the rice milling container 4 is agitated, and the rice grains and the rice milling container 4 rub against each other, whereby the rice is milled. . The rice cake separated from the brown rice by the polished rice passes through the mesh portion 34 and is then stored in the rice cake acceptor 3.

  Next, control in the “GABA” mode and “GABA rice milling” mode, which is one of the characteristic configurations of the present invention, will be described. These controls are performed by control means such as a control circuit (not shown) built in the rice mill main body 2.

  First, in the “GABA” mode, the GABA rice milling switch 124 is operated to select “brown rice”. In this case, brown rice is put in the polished rice container 4. Further, the finish timer switch 126 is operated to select the finish time of the GABA brown rice. In the present embodiment, any one of 5 hours, 7 hours, and 9 hours can be selected as the set times Ta, Tb, and Tc.

Thereafter, when the operation / stop switch 122 is pressed, the "GABA" mode, that is, the GABA enrichment operation is started. In the “GABA” mode, as shown in FIG. 15, the linear heater 12 is turned on from the beginning, and is turned off when the temperature rises to the upper limit temperature t _1, and is turned on when the temperature falls to the lower limit temperature t ₂ after turning off. Become. Thus, the linear heater 12 is repeatedly turned on and off between the upper limit temperature t ₁ and the lower limit temperature t _2. In this embodiment, the upper limit temperature t ₁ is 110 ° C., and the lower limit temperature t ₂ is 90 ° C. The energization of the linear heater 12 is performed for a time obtained by subtracting a predetermined time Td from the set times Ta, Tb, and Tc. In this embodiment, the predetermined time Td is 2.5 hours. That is, if the set time Ta = 5 hours is set, the linear heater 12 is energized for 2.5 hours, and if the set time Tb = 7 hours is set, the linear heater 12 is energized for 4.5 hours, If the set time Tc = 9 hours is set, the linear heater 12 is energized for 6.5 hours. The linear heater 12 is not energized at all for the remaining 2.5 hours of the set times Ta, Tb, and Tc. That is, the last predetermined time Td of the set times Ta, Tb, and Tc is a non-heating time.

  As described above, the linear heater 12 is wound around the outer periphery of the interior member 10. And since the said rice bran receptacle 3 is provided between the said rice milling container 4 and the interior member 10, this rice bran receptor 3 may interfere with heating the brown rice in the said rice milling container 4. FIG. However, as described above, since the soot receptacle 3 has the heat transfer portion 26 in which the heat conductive metal plate is formed in a cylindrical shape, the heat generated by the linear heater 12 is transmitted from the interior member 10 to the soot. The heat is transferred to the space inside the soot receptacle 3 via the heat conductive portion 26 of the acceptor 3. Thereby, since the brown rice in the said rice polishing container 4 is heated efficiently, GABA contained in brown rice can be enriched efficiently.

The evaporation heater 77, as shown in FIG. 14, the operation start in the "GABA" mode, repeat the energization of the energization stopping the energization time T ₂ of the stop time T ₁ by the predetermined number of times N _1. In this embodiment, the stop time T ₁ = 1 minute, the energization time T ₂ = 1 minute, and N ₁ = 30 times. That is, the evaporation heater 77 is repeated 30 times per minute pause and the energization of 1 minute alternately. Accordingly, the pause and heating by the evaporating heater 77 are repeated for ( T ₁ + T ₂ ) × N ₁ = 1 hour.

The pump 71, as shown in FIG. 14, from the start of the operation of the "GABA" mode, repeats the driving of the stop and the drive time _{T 4} of the stop time _{T 3} by the predetermined number of times _{N 1.} In this embodiment, the stop time T ₃ = 1 minute 54 seconds, the drive time T ₄ = 6 seconds, and N ₁ = 30 times. That is, the pump 71 repeats the stop of 1 minute 54 seconds and the drive of 6 seconds 30 times alternately. Therefore, the pause and drive by the pump 71 are repeated for (T ₃ + T ₄ ) × N ₁ = 1 hour. Note that T ₁ + T ₂ = T ₃ + T ₄ , and ( T ₁ + T ₂ ) × N ₁ = (T ₃ + T ₄ ) × N ₁ . Further, T ₂ > T ₄ , and preferably T ₂ >> T ₄ . Therefore, after the evaporation heater 77 is sufficiently heated, the water in the water tank 62 is sent to the steam unit 72 by the pump 71. And all the water sent to the said steam unit 72 evaporates reliably. Further, the high temperature steam generated by the steam unit 72 passes through the main body side steam path 76 and the lid body side steam path 101 from a terminal opening 105A provided at the center of the inner lid 82 of the lid body 6. , And supplied to the rice mill container 4.

As shown in FIGS. 13 and 14, the drive mechanism 13 is driven for a stirring time T ₈ after a predetermined time T ₅ , T ₆ , T ₇ has elapsed since the start of the operation in the “GABA” mode. In this embodiment, after the start of the operation, the stirring time T ₈ = 3 seconds after the predetermined time T ₅ = 20 minutes, the predetermined time T ₆ = 40 minutes, and the predetermined time T ₇ = 60 minutes, respectively. Then, the rice milling body 5 rotates. Therefore, the brown rice heated while supplying moisture in the rice mill container 4 is agitated by the rotation of the milled rice body 5, and moisture by steam is supplied uniformly. Furthermore, the drive mechanism 13, the operation start, setting time Ta, and the driving and Tb, the time obtained by subtracting the stirring time T ₉ from Tc elapses, stops after lapse of driving time T _9. 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.

_{Incidentally, 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.

  As described above, the brown rice is heated by the linear heater 12 that is a heater, the high-temperature steam is supplied to the brown rice by the pump 71, and the brown rice is stirred by the milled rice body 5, and the brown rice is further heated. Then, brown rice containing a large amount of GABA is finished by natural cooling for a predetermined time Td.

  Next, in the “GABA rice milling” mode, the GABA rice milling switch 124 is operated to select “white rice”. In this case as well, brown rice is put in the milled rice container 4. Further, the finishing timer switch 126 is operated to select the finishing time of GABA white rice. In the present embodiment, any one of 5 hours, 7 hours, and 9 hours can be selected as the set times Ta, Tb, and Tc.

  The operations of the linear heater 12, the evaporation heater 77, and the pump 71 are the same as those in the “GABA” mode described above.

As shown in FIG. 16, the drive mechanism 13 is driven for a drive time T ₈ after a predetermined time T ₅ , T ₆ , T ₇ has elapsed from the start of GABA milling. In this example, after the start, after the predetermined time T ₅ = 20 minutes, after the predetermined time T ₆ = 40 minutes, and after the predetermined time T ₇ = 60 minutes, the driving time T ₈ = 3 seconds, respectively, The polished rice body 5 rotates. Furthermore, the drive mechanism 13, the operation start, setting time Ta, and the driving and Tb, the time obtained by subtracting the rice required time _{T 10} from Tc elapses, stops after rice required time _{T 10} elapses. In addition, rice required time T ₁₀ will vary by the amount of rice. If, when rice required time _{T 10} was 10 minutes, in the present embodiment, 4 hours and 50 minutes from the start of operation (or 6 hours 50 minutes, 8 hours and 50 minutes) Upon expiration, the drive mechanism 13 is 10 Driven for a minute, the milled rice body 5 rotates to mill the rice.
