At this time, the clamp body 66 is connected to the inclined guide surfaces 34a, 6
3, the guide hole 62 is reliably advanced and engaged with the locking hole 34 along one side of the locking hole 34 and the guide hole 62.

The lid body 25 has a rotation prevention seat 33 and a rotation prevention engagement surface 61.
The fitting cylindrical portion 32 of the lid body 25 is engaged with the cylindrical portion 59 of the clamp case body 54, and the engaging step portion 32a is engaged with the enlarged diameter step portion 60, and at the same time, the engagement of the main body 13 is stopped. Joint protrusion 24
and the engagement recess 65 of the clamp case body 54 are engaged, the relative positions of the gear case 8, the main body 13, and the lid 25 provided on the base body 1 are regulated, and the input port 14 of the main body 13 is in a state facing upward. is held in

At this time, the rotating shaft 38 is connected to the drive shaft 9 by the coupling part 10.
, 39, and the coupling portion 39 of the rotating shaft 38 abuts against the inner end of the drive shaft 90 and the force coupling portion 10, so that the rotating shaft 38 is restricted from moving toward the proximal end, and the rotating shaft 38 is connected to the base of the rotating body 36. A space 27a is maintained between the end face and the bearing 21.

In this state, the main body 13 is horizontally supported by the support portion 64 of the clamp case body 54.

When the electric motor 7 is driven by a switch operation, the drive shaft 9 is rotated at a reduced speed via the gear transmission mechanism.

The rotating shaft 38 is rotated through engagement of the coupling portion 10° 39 with the drive shaft 9, and the rotating body 36 is rotated.

In this state, when the material to be cooked is introduced from the material input port 14 and pushed by the push rod 16, the material is cut by the cutting blade 40 of the rotating body 36 and the edge of the opening of the input port 14, forming a spiral shape. It is transferred to the tip side of the rotary body 36 by the cutting blade section 40 .

The cut material is then sent to a pressing section 41 having a spiral wing section 45 continuous to the spiral cutting blade section 40 .

This compressed portion 41 is comprised of troughs 46 and peaks 47 of the spiral wing portion 45.
Since the difference in diameter between the main body 13 and the trough 46 gradually decreases toward the tip, the extracted liquid is sequentially crushed and squeezed between the inner surface of the main body 13 and the trough 46, and the extracted liquid is sent to the juice outlet 17 at the bottom of the filter 18. It flows out through the hole and drips into the juice container 79.

The rotating force of the rotating body 36 is applied to the main body 13, the lid 25, and the lid 2.
5 and the clamp case body 54, no force in the direction of rotation of the rotating body 360 is applied.

Further, when the electric motor 7 is stopped by operating a switch after cooking is completed, the electric motor 7 is driven to rotate in the opposite direction by the switch, and the inner surface of the main body 13, the cutting blade part 40 of the rotating body 36, and the pressing part 41 are rotated in the opposite direction.
The cooking material injected between the main body 13 is transferred to the proximal end of the main body 13 on the enlarged diameter side, and the rotary body 36 can be easily extracted.

After cooking, when the push button 74 is operated to push down the release actuator 71, the operating surface 70 of the release actuator γ1 pushes the actuated surface 69 of the clamp body 66, and the clamp body 66 resists the spring 67. The clamp body 66 and the lid body 25 are pushed and moved.
The engagement of the locking hole 34 is released.

In this state, the lid 25 of the main body 13 is attached to the clamp case body 54.
It can be removed from the

Then, by removing the lid 25 of the main body 13 that has been removed from the base 1 side, the rotating body 36 can be easily pulled out from the opening by grasping the knob 50 protruding from the opening of the main body 13 of the rotating body 36. .

In the above embodiment, the clamp case body 54 is provided with a support base portion 64 that supports the main body 13, but in this structure, the clamp case body 54 is attached to the base body 1 via the gear case 8 and the electric motor T, so that rotation is not possible. Although the shaft 38 and the drive shaft 9 are reliably positioned, the support portion 64 may be provided on the base body 1.

Further, the engagement recess 65 may be formed in the main body 13 and the engagement protrusion 24 may be formed in the clamp case body 54.

According to the present invention, positioning protrusions that engage with each other are formed on the cooking machine main body and the lid, and a locking surface that engages with the locking seat formed on the lid is formed on the base. Since the detent engaging portion is formed to engage the detent engaging portion formed on the main body, when the cooking machine main body is attached to the base, the detent engaging portion of the main body is connected to the detent engaging portion of the base. The locking seat of the lid body is engaged with the locking engagement surface of the base body, the body and lid body are positioned and held relative to the base body, and the body and lid body are positioned with respect to each other by positioning protrusions. Because of this, there is no need for positioning operations such as the input port, and it is easy to clean and assemble after cooking. Also, the force in the rotational direction of the rotating body that rotates inside the main body is transferred between the main body and the lid. It does not act on the threaded part between the lid and the base, and does not apply unreasonable force to the main body, the lid, and the base, resulting in stable strength, and prevents the lid from being excessively tightened to the main body. There is no chance of the cooking machine becoming attached to the base, the lid will not be difficult to remove from the main body, and it can be easily disassembled. Safety is improved as the product is not used in an unprotected state.
