Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a juicer, which cuts and crushes the material to be cooked with a cutting blade at the upper end of the rotating body, and applies the material to the squeezing portion of the rotating body. This invention relates to a centering configuration of a rotary body in a device that squeezes juice by squeezing the juice.

(Prior art) Conventionally, in this type of juicer, the material to be cooked is cut and crushed by a cutter provided on the upper surface of a rotary body that rotates around a vertical rotation axis, and this material is formed into a spiral shape on the circumferential surface of the rotary body. A juicer has been developed in which the juicer is extracted and separated by squeezing with a shaped squeezing part, so that air bubbles are not mixed in the juicer and the vibration noise is reduced (Japanese Patent Application Laid-Open No. 194710/1983).

Conventional juicers such as this have a problem in that the cooking chamber cannot be easily cleaned after the juice processing, and cleaning workability is poor. Therefore, the cooking case is fitted and held in a support case that is detachably attached to the device body.
A juicer has been developed that allows the support case and cooking case to be taken out of the container and cleaned, making cleaning work easier.

(Problems to be Solved by the Invention) However, in a juicer that has a structure in which the cooking case is fitted and held in a support case that is detachably attached to the container body, it is difficult to center the support case, the cooking case, and the rotating body. The deviation of the center caused vibrations.

The present invention was devised in view of the above-mentioned problems, and provides a juicer in which the centers of the support case, the cooking case, and the rotating body can be easily aligned and generate less vibration.

[Structure of the invention]

(Means for Solving the Problems) The extractor of the present invention is a rotating body that has a plate-shaped cutter having a cutting blade on its upper surface, forms a spiral squeezing portion on its circumferential surface, and rotates around a vertical rotation axis.

to face. Furthermore, the rotating body 40 is fitted into the cooking case 32, the rotating shaft 51 protruding from the lower end of the rotating body 40 is made to protrude downward from the through hole 47 of the cooking case 32, and the coupling part 54 is connected to the coupling part 8 of the main shaft 7. to engage.

Next, by placing the lid 62 on the upper surface 16 of the container body 1 and pivotally supporting the rotating shaft 49 of the rotating body 40 on the bearing 67, the rotating body 40 can be centered, and then the locking protrusion 65 is attached to the container body. 1 into the widened part 19a of the locking hole 19 formed on the top surface of the cover 6.
2, the locking protrusion 65 locks into the locking hole 1.
At the same time, the locking projection 65 is engaged with the locking hole 18 of the container body 1, and the locking projection 66 is engaged with the locking projection 29 of the support case 20.
4 is attached to the vessel body 1 and also includes a support case 20
The spigot fitting part 63 of the lid body 62 is fitted into the spigot fitting part 36 of the cooking case 32, and the cooking case 32 can be centered.
The upper end of the cooking case 32 is brought into contact with the inner surface of the lid body 62, and the lip portion 61 of the packing 60 is brought into close contact with the inner surface of the lid body 62 with the spigot fitting portion 63 in between. It is sandwiched and held between the body 62 and the body 62.

In this state, when the electric motor 3 is driven by a switch operation, the output side main shaft 7 of the reduction gear mechanism 6 rotates every minute.
It is rotated at a reduced speed of 2000 to 3000 times. In this state, the material to be cooked is inputted from the input port 68 and pressed against the cutter 57 by the push rod 69. At this time, the rotating body 40 is rotated by coupling with the main shaft 7, and the material to be cooked is cut and crushed by the cutting blade 59 of the cutter 57. The material cut and crushed by the cutting blade 59 is sent out toward the outer circumference of the cutting blade 59, and the material to be cooked that has been cut and crushed is sent from the upper surface periphery of the rotating body 40 to the feeding guide portion 33 of the cooking case 32. Sequentially fed into squeezing section 5
6 and the cooking case 32.
The material to be cooked that has been cut and crushed by the cutter 57 is transferred to the squeezing portion 58 of the rotating body 40 and the cooking case 31.
This material to be cooked is sequentially squeezed to extract the juice content, and the juice content is filtered from the juice outlet 37 by the filter 38 and flows into the juice outflow chamber 27. The fuel flows into the youth container 30 from the youth outlet 28 of the youth outflow chamber 27 . Further, the squeezed dregs of the material to be cooked is sent to the lower part of the cooking chamber 48 and is discharged from the dregs discharge port 39 of the cooking case 32.
The waste discharged from the waste discharge port 39 pushes the adjustment plate 44 open against the elasticity of the spring 45 and is stored in the waste storage portion 25 of the support case 20. When discharging the dregs, the lower edge of the adjusting plate 44 is connected to the cooking case 32.
Since the cooking case 32 is in contact with the bottom of the cooking case 32, the cooking case 32 is prevented from being lifted upward by the reaction of the scraps pushing the adjusting plate 44 open. In addition, since the diameter of the bottom of the rotating body 40 is larger than the through hole 47 of the bottom 41 of the cooking case 32, the scraps that have entered the bottom of the rotating body 40 press the bottom of the cooking case 32 downward and flow upwards of the cooking case 32. lifting is prevented. In addition, the residue that has entered the lower part of the cooking case 32 through the through hole 47 is removed by the packing 53 into the supporting case 2.
0 is prevented from flowing outward. Then, the residue discharged from the cooking case 32 into the waste storage section 25 is prevented from flowing back into the cooking case 32 by the adjusting plate 44.

Also, during cooking, the spiral groove-shaped squeezing portion 5 of the rotating body 40
Even if the rotating body 40 is pushed upward due to the reaction of the material feeding by 6, the upper surface of the cutter 57 comes into contact with the lower surface of the bearing 67 that pivotally supports the rotating shaft 49 of the rotating body 40, and a force is applied to push up the lid 62. Due to the engagement between the spigot fitting part 63 and the spigot part 36 of the cooking case 32, even if the material cut and crushed by the cutter 57 and the separated juice are scattered outward due to centrifugal force, the packing 60 will not be damaged. Lip part 6
1 is pressed against the inner surface of the lid body 62, and the packing 60
The sealing effect of the lip portion 61 is increased by increasing the internal pressure, and the juice will not leak out from the lid 62.

In addition, when cleaning after use processing, the lid body 62
When the locking protrusion 65 is positioned in the widened part 19a of the locking hole 19 by rotating in the opposite direction, the locking protrusion 64 of the lid body 62 is disengaged from the engagement hole 18 of the container body 1. , the engagement protrusion 66 of the lid 62 has come off the engagement protrusion 29 of the support case 20, and the lid 6
The second locking protrusion 65 can be removed from the widened portion 19a of the locking hole 19 of the container body 1, and the lid body 62 can be removed from the container body 1. Next, with the lid 62 removed, the rotating body 40, the cooking case 32, and the support case 2 are removed.
0 from the vessel 1 and clean it.
