A structure is adopted in which a cooking machine main body, in which a rotating body having an inlet and an outlet, is removably attached to the side surface of a base body, and the rotating body is coupled to a drive shaft. In this structure, the drive shaft is linked to the electric motor via a speed reduction mechanism, so the rotating body generates a large rotational torque, and the force acting in the direction of removing the main body from the base, which is the axial direction of the rotating body, is a small force. Therefore, if a single clamp body receives the force applied in the rotation direction due to the rotation of the rotating body of the main body and the force applied in the direction of removal of the main body, a large force will be applied to the clamp body, and the clamp body will need strength. There is a major problem.

Even if rotational force is applied to the main body 4 due to the resistance during the rotation operation of the rotary body 33 for cutting, crushing and squeezing during this cooking, the rotary body 33 is rotated in the opposite direction to the rotation direction of the support body 50. The screw 54 fixed to the support 50 is attached to the base 1.
Since the protrusion 58 is engaged with the engagement hole 57 of the support body 50, the main body 4 can be rotated in the direction of rotation of the rotating body 33. Moreover, the main body 4 is attached to the base body 1 without being moved in the axial direction in the removal direction.

After cooking, when the main body 4 is rotated in the opposite direction to the rotating direction of the rotating body 33 during the cooking process by operating the knob 63, the support 50 with which the protrusion 58 of the main body 4 is engaged also moves in the same direction. The clamp body 45 is rotated by the rotation of the support body 50.
0, this clamp body 45 is slid along the guide part 55 of the base body 1, and is pushed outward against the spring piece 46 by the clamp release part 56 of the guide part 55, and the clamp hook is rotated. The engagement with the portion 32 is released. In this state, the main body 4 can be removed from the base 1.

Further, the main body 4 can also be removed by rotating the main body 4 and rotating the clamp support 50 using the protrusion 58 thereof.

Then, by removing the lid 23 of the main body 4 that has been removed from the base 1, the rotating body 33 can be pulled out from the opening 16. When the rotary body 33 is pulled out, the rotary body 33 has a spiral cutting edge portion 36 and a compressing portion 37 formed integrally with each other, making it easy to handle. The rotating body 33 also has a larger diameter at the tip side of both the outer periphery of the cutting blade part 36 and the outer periphery of the compressing part 37, so it is easy to insert and remove the rotating body 33. 33 can be easily cleaned.

In the above embodiment, a structure has been described in which the electric motor 7 is decelerated and driven by a worm gear 9 and a wheel gear 10, but the rotary shaft 8 and the drive shaft 12 may be interlocked by belt interlocking. .

Further, the rotating shaft 34 of the rotary body 33 and the drive shaft 12 are coupled together in the transmission mechanism accommodating portion 3 of the base body 1, so that the drive shaft 12 is not exposed outside the base body 1 and is not rotated. Although this prevents the danger of touching with hands, it may be connected to the rotating shaft 34 of the rotating body 33 outside the base 1.

Furthermore, in the embodiment described above, the rotating shaft 34 is attached to the rotating body 33.
Although the structure in which the rotating body 3 is penetrated has been explained,
3, the bearing may protrude from both ends without penetrating it, and the lid body 23 is removably provided at both ends of the body 4, and the coupling portion 35 of the rotating shaft 34 is made to protrude from the lid body on the proximal end side of the body 4. 29 may be provided. Further, the rotating shaft 34 and the coupling portions 35, 13 of the drive shaft 12 may be formed separately.
