  As shown in FIGS. 8B and 8C, when the cooking container 80 reaches the base body 210, the base portion 360 hits the contact wall 216 of the base body 210 and the cooking container 80 cannot move backward. . In the cooking container 80, the four leg portions 374 are placed on the flat surface 214a of the elevator table 214 corresponding thereto. At this time, the cooking container 80 is in the raised position, and the input cam 350 and the output cam 120 are aligned in the horizontal direction (front-rear direction) but separated from each other in the vertical direction. The claw portion 364 on the cooking container 80 side is on the same circular orbit as the engagement claw portion 222 on the installation base 50 side, but is in a separated state. From this state, the user holds the second handle portion 312 and rotates the cooking container 80 in the clockwise direction that is the mounting direction. At this time, the user can know the mounting direction from the first notation 313a attached to the notation plate 313 (see FIG. 6). When rotating, the cooking container 80 is guided by the left and right guide wall parts 215 and the contact wall part 216, so that the user can easily rotate the cooking container 80. Note that when the user accidentally rotates the cooking container 80 in the detaching direction, the leg portion 374 hits the stopper portion 214c, and the rotation of the cooking container 80 is stopped.

  As shown in FIGS. 9 (a) and 9 (b), when the cooking container 80 is rotated in the mounting direction, the leg 374 moves on the flat surface 214a of the lifting platform 214 to the inclined surface 214b. Down the inclined surface 214b. Thereby, the cooking container 80 descend | falls and the position of the nail | claw part 364 falls in connection with this. At this time, since the leg portion 374 is made of resin, the leg portion 374 is easily slid and easily moved on the lifting platform 214.

  When the leg part 374 descends the inclined surface 214 b and reaches the surface 212 a of the outer peripheral part 212 of the base body 210, the position of the claw part 364 is lowered to a position where the claw part 364 can enter under the engagement claw part 222. Thereafter, when the cooking container 80 is further rotated, as shown in FIGS. 9C and 9D, the claw portion 364 overlaps with the engaging claw portion 222 and engages with the upper surface 364a of the claw portion 364. The bottom surface 222a of the portion 222 comes into contact. Thereby, the cooking container 80 cannot be rotated any more in the mounting direction. The cooking container 80 is in the lowered position, and the input cam 350 is connected to the output cam 120. The input blade 351 of the input cam 350 is engaged with the output blade 121 of the output cam 120, the blade shaft 330 of the cooking vessel 80 is connected to the blade drive shaft 110, and the stirring blade 340 can be rotationally driven by the power of the blade drive motor 130. It becomes a state. Moreover, when the nail | claw part 364 contacts the engagement nail | claw part 222, the upward movement of the cooking container 80 is controlled.

  Thus, the mounting of the cooking container 80 on the installation base 50 is completed.

  The stirring blade 340 is rotated in one direction, and the rotation direction is a clockwise direction when viewed from above, that is, a direction in which the upper surface 364a of the claw portion 364 and the bottom surface 222a of the engagement claw portion 222 abut. The Therefore, the cooking container 80 does not rotate due to the rotation of the stirring blade 340.

  When removing the cooking container 80 from the installation base 50, the procedure reverse to that at the time of mounting is executed. That is, the user holds the second handle portion 312 and rotates the cooking container 80 in the counterclockwise direction, which is the removal direction. The leg 374 goes up the inclined surface 214b of the lifting / lowering table 214 to the flat surface 214a, and the cooking container 80 is raised from the lowered position to the raised position. As a result, the input cam 350 is separated from the output cam 120. Thereafter, the user pulls the cooking container 80 forward while sliding on the guide plate 230. In addition, when the cooking container 80 is rotated too much in the removal direction, the leg part 374 hits the stopper part 214c and the rotation of the cooking container 80 is stopped.

  In this way, the removal of the cooking container 80 from the installation base 50 is completed.
