The temperature sensor 47 detects the temperature during cooking of the food in the cooking container 1, and the output is input to the control panel. The temperature sensor 47 is arranged in the part that detects the temperature of the food most accurately, but a plurality of temperature sensors 47 are further arranged in the cooking container 1 to detect the average value or the maximum temperature and the minimum temperature of each temperature sensor. You can also.

  The stirring means 7 is supported by an upper drive box 49. The drive box 49 is supported on the upper portion of the support column 51 via a shaft 53 so as to be able to be retracted. A hydraulic cylinder device 55 is provided between the drive box 49 and the support column 51 to prevent the drive box 49 from rotating.

  A geared motor 57 is provided in the base end portion of the drive box 49. A sprocket 61 is provided on the output shaft 59 of the geared motor 57. A drive shaft 63 is provided at the tip of the drive box 49. A sprocket 65 is provided on the drive shaft 63. A chain 67 is hung between the sprockets 61 and 65.

  FIG. 3 is a cross-sectional view showing the rotation drive unit 68 of the stirring means 7. As shown in FIG. 3, the eccentric rotary frame 41 is attached to the drive shaft 63 so as to be integrally rotatable. The eccentric rotating frame 41 includes a main body 69 and an eccentric 71. A main body 69 is attached to the drive shaft 63, and the rotating frame 43 is rotatably supported by the eccentric portion 71.

  The rotating frame 43 includes a hollow shaft portion 73 and a cross-shaped flange portion 75, and a transmission shaft 77 is rotatably supported on an axial center portion of the hollow shaft portion 73, and the branch shafts 33, 35 and 39 and the auxiliary shaft 45 are attached.

  The branch shaft 39 is formed in a hollow shape, and a transmission shaft 79 is rotatably supported on the shaft center portion.

  A gear 89 is attached to a lower end portion of the transmission shaft 77 and meshes with a gear 91 attached to the upper portion of the transmission shaft 79.

A bevel gear 95 disposed in the gear box 93 is attached to the lower end portion of the transmission shaft 79. The gear box 93 is attached to the lower end of the branch shaft 39. The gear box 93 supports a connecting shaft portion 97 orthogonal to the transmission shaft 79. The connecting shaft 97 is provided with a bevel gear 99 and meshes with the bevel gear 95. The stirrer 31 is detachably linked to the connecting shaft portion 97 .

  FIG. 4 shows the stirrer, where (a) is a front view and (b) is a side view.

As shown in FIG. 4, the stirrer 31 includes a stirring shaft portion 101 and a stirring blade portion 103. The stirring shaft portion 101 includes a coupling flange 105, and is detachably coupled to the connecting shaft portion 97 with a bolt and nut. Each stirring blade portion 103 is formed, for example, by bending a wire, and is provided in the axial comb shape with a predetermined interval in the circumferential direction with respect to the stirring shaft portion 101. The stirring blade portion 103 is set so that the radius of rotation gradually decreases slightly from the coupling flange 105 side to the other end side. The stirring blade portions 103 arranged in a comb-teeth shape in the axial direction of the stirring shaft portion 101 are provided in four rows at 90 ° arrangement in the circumferential direction, and the adjacent stirring blade portions 103 at 90 ° They are offset by half the axial width.
When the geared motor 57 is driven, the drive shaft 63 is rotationally driven through the sprocket 61, the chain 67, and the sprocket 65.

  When the drive shaft 63 is driven, the eccentric rotating frame 41 rotates, and the eccentric portion 71 rotates eccentrically around the axis of the drive shaft 63. As the eccentric portion 71 rotates eccentrically, the rotating frame 43, the transmission shaft 77, and the branch shaft 37 also rotate eccentrically. At the same time, the hollow shaft 73 and the transmission shaft 77 rotate through the meshing of the gears 81 and 83 and the gears 85 and 87.

  The rotation of the hollow shaft portion 73 causes the flange portion 75 to rotate, and the branch shafts 33, 35, 39 and the auxiliary shaft 45 pivot about the axis of the hollow shaft portion 73.

  Due to the rotation of the transmission shaft 77, the connecting shaft portion 97 is rotated through the gears 89 and 91, the transmission shaft 79 and the bevel gears 95 and 99. The stirrer 31 loosens and rotates through the stirring shaft portion 101 by the rotation of the connecting shaft portion 97.

  Accordingly, the scrapers 25 and 27, the stirrer 31, and the temperature sensor 47 are swung around the axis of the eccentric portion 71 of the eccentric rotating frame 41 with respect to the cooking container 1 by the drive, The eccentric part 71 revolves by eccentric rotation with respect to the axis of the drive shaft 63.

  The rice contained in the cooking container 1 can be scraped and scooped up from the bottom 11 by the swiveling and revolving movements of the scrapers 25 and 27 by the rotation, and stirred and cooked.

  The scraper 29 can scrape the inner surface of the body portion 13 of the cooking container 1 by the eccentric rotation of the eccentric portion 71.

  When the scraper 25 is scraped and moved, the stirrer 31 rotates in front of the scraper 25, so that the rice scraped and collected by the scraper 25 can be loosened by the stirrer 31. The rice scraped and collected by the scraper 27 and moved to the side of the scraper 25 is supplied to the end portion side of the stirrer 31 and sequentially moves in the axial direction of the stirrer 31 while being loosened by the stirrer 31.

  By such scraping stirring and loosening stirring, the fried rice can be cooked accurately.

  After fried cooking, as shown in FIG. 5, the drive box 49 is rotated about the shaft 53 and raised, the cooking container 1 is rotated about the shaft 21 and tilted, and the fried rice cooked in this tilted state is impossible. It can discharge without. In addition, the cooking container 1 can be washed without difficulty while the cooking container 1 is tilted.
