Further, the electric motor T is driven to rotate in the forward direction by closing a switch (not shown), and can be driven to rotate in the reverse direction by operating this switch.

Furthermore, it is also possible for the reverse rotation drive circuit to be formed immediately before opening the switch.

Next, how to use this cooker will be explained.

When the lid body 25 is screwed into the base end opening of the main body 130, the main body 13
The threaded portion 22 and the threaded groove 30 of the lid body 25 are the
3.31 are tightened until they engage with each other, and the engagement of both the protrusions 23 and 31 allows the position of the main body 130 input port 14 and the position of the rotation stopper seat 33 of the lid body 25 to be relatively positioned.

In this state, when the fitting cylinder part 32 of the lid body 25 is fitted to the clamp case body 54 attached to the base body 1 with the rotation stopper seat 33 and the rotation prevention engagement surface 61 aligned, the engagement guide surface 35 is fitted. The clamp body 66 engages with the engagement surface 66a of the clamp body 66.
The fitting cylinder portion 32 is moved backward against the spring 67.
is fitted into the cylindrical part 59 of the clamp case body 54, and when it reaches the position of the locking hole 34 of the lid body 25, the clamp body 66 advances under the pressing force of the spring 6T, and the clamp body 66 enters the locking hole 34. engaged.

At this time, the clamp body 66 is attached to the inclined guide surfaces 34a, 63.
As a result, the guide hole 62 is reliably advanced and engaged with the locking hole 34 along one side of 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, the engaging step portion 32a is engaged with the enlarged diameter step portion 6o, and at the same time, the main body 13 The engaging protrusion 24 of the clamp case body 54 is engaged with the engaging recess 65 of the clamp case body 54, and the relative positions of the gear case 8, the main body 13, and the lid body 25 provided on the base body 1 are regulated, and the insertion opening 14 of the main body 13 is regulated.
is held facing upward.

At this time, since the clamp case body 54 of the rotary shaft 38 is attached to the gear case 8, there is no dimensional deviation with respect to the drive shaft 9, and the rotary shaft 38 is attached to the drive shaft 9 with the coupling portion 10.
．． The coupling portion 39 of the rotating shaft 38 abuts against the inner end of the force-sampling portion 1o of the drive shaft 90, and the rotating shaft 38 is restricted from moving toward the proximal end, and the rotating body 3
A space 27a is maintained between the end face on the base end side of the bearing 27 and the bearing 27.

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

When the switch is closed, the electric motor 1 is driven, and the drive shaft 9 is rotated at a reduced speed through the gear transmission mechanism.

The rotating shaft 38 is rotated by the drive shaft 9 through engagement of the cup link parts 10 and 39, and the rotating body 36 is rotated.

In this state, when the material to be cooked is put into the cooking material input port 14 and pushed by the push rod 16, the material is cut into a spiral shape by the cutting blade part 40 of the rotating body 36 and the opening edge of the input port 14. 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. The juice passes through the hole 18a and flows out into the juice container 1.
Dropped at 9.

Then, the pomace containing fibers is discharged from the pomace discharge port 19 to the pomace receiver 77.

This dregs discharge port 19 is located above and on the lower side of the juice outlet 17 with respect to the rotating direction of the rotating body 36, so that after the liquid content is extracted at the juice outlet 17, it is discharged from the dregs discharge port 19. The dregs are intensively discharged without the liquid being absorbed again, improving squeezing efficiency.

The input port 14 of the main body 130 is supported by a support portion 64 of the clamp case body 54, and the pressing force of the material to be cooked when pressed by the push rod 16 can be received by the support base portion 64, and the main body 13 is stably supported and cooking processing can be performed in a stable state.

Further, the clamp case body 54 is loosely fitted to the fitting portion 12 of the base body 1 via an elastic body 82 and attached to a case 8 provided on the electric motor 7 . This prevents the vibration of the motor 7 caused by the load at startup of the motor 7 or sudden changes from being transmitted to the base 1 .

Further, when the electric motor 7 is stopped by operating a switch after cooking is completed, the electric motor T is driven to rotate in reverse 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
The cooking material injected between the main body 13 moves to the proximal end side on the enlarged diameter side of the main body 13, and the rotating body 36 can be easily extracted.

Further, after cooking, when the push button 74 is operated to push down the release actuator 71, the actuating surface 70 of the release actuator 71 pushes the actuating 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
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 moved from the opening 21 by grasping the knob 50 protruding from the opening of the main body 13 of the rotating body 36.
It can be pulled out from.

Alternatively, the main body 13 may be formed with an engaging recess 65, and the clamp case body 54 may be formed with an engaging protrusion 24.

According to the present invention, an electric motor is attached to a base body with an elastic body interposed therebetween, a drive shaft interlocked with the electric motor is mounted on a case provided on the electric motor, and a rotating shaft coupled to the drive shaft is mounted on the case. Since a clamp case body is provided to attach the cooking machine body equipped with a rotating body, there is no possibility of misalignment between the rotating shaft provided on the main body, which is attached to the clamp case body, and the drive shaft linked to the electric motor. (The main body can be easily attached without applying unreasonable stress to the base body.)

In addition, by maintaining a gap between the clamp case body and the mating part of the base body, it is possible to prevent the motor and the clamp case body from transmitting vibrations and vibrations of the motor when starting the motor or due to sudden changes in load. .

Furthermore, by fitting the clamp case body into the fitting portion of the base body through the elastic body, vibrations of the clamp case body caused by vibrations of the electric motor can be buffered, and vibrations of the electric motor can also be transmitted to the base body.
