[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a juicer, which compresses a cut cooking material with a spiral groove-shaped squeezer of a rotating squeezer body to produce a liquid. Regarding the juicer that squeezes the juice.

(Technology from the past) Conventional juicers of this type are disclosed in, for example, Japanese Patent Application Laid-open No. 59-194.
As described in Japanese Patent No. 710, a squeezing case is formed with a juice outlet part and a dregs discharge part having a filter, and a spiral groove-shaped squeezing part is formed on the outer periphery of the squeezing case, which is opposite to the inner periphery of the squeezing case. a shaped squeeze body is rotatably fitted into the squeeze case, and a cooking material input cylinder part with a bottom opening facing a cutter provided on the top surface of the squeeze body is protruded from a lid body that covers the top opening of the squeeze case; The material to be cooked that is introduced from the upper opening of the input cylinder of the lid body is cut by a cutter provided on the upper surface of the rotating squeezing body, and the cut material is placed on the outer circumference of the squeezing body. The juice is compressed and pulverized by a spiral groove-shaped squeezer formed on the outer periphery of the squeezer body facing the inner periphery of the squeezer case, and the juice is extracted. A structure was adopted in which the squeezed dregs were discharged from the dregs discharge section.

(Problems to be Solved by the Invention) In the above-mentioned conventional juicer, the material to be cooked cut by the cutter is crushed and squeezed in the squeezing part of the squeezing body, and the juice is discharged from the juice outlet part of the squeezing case. The dregs are discharged from the dregs discharge part, but the dregs which are not discharged from the dregs discharge part enters between the inner bottom surface of the squeezing case and the outer bottom surface of the squeezing body, and the outer bottom surface of the squeezing body is lifted from the inner bottom surface of the squeezing case. It is necessary to reduce the bottom area of the squeeze case, and there is also the problem that heat is generated when the juice is processed for a long time.

The present invention was made in view of the above-mentioned problems, and prevents the scraps of the cooking material from entering between the outer bottom surface of the squeezing body and the inner bottom surface of the squeezing case, thereby preventing the scraps from getting caught up in the rotating shaft. The present invention provides a juicer that can prevent this from occurring.

[Structure of the invention]

(Means for Solving the Problems) The juicer of the present invention includes a squeezing case in which a juice outlet section having a filter and a dregs discharge section are formed, and an outer periphery rotatably housed in the squeezing case and facing an inner circumferential surface. a substantially cylindrical squeezing body that has a spiral groove-shaped squeezing portion formed on its surface and is rotated by being removably engaged with a rotating shaft protruding from the inner bottom of the squeezing case; and the squeezing case and the squeezing body. a lid body having a cooking material input cylinder part disposed inside the squeezing body to cover an opening of the squeezing body; It is equipped with a cutter that maintains a small gap between it and the lower opening surface,
An annular protrusion protruding downward is formed on the periphery of the outer bottom surface of the squeezing body opposite to the inner bottom surface of the squeezing case, and a recess into which the protrusion fits into the outer periphery of the inner bottom surface of the squeezing case is formed. The invention is characterized in that the gap between the inner bottom surface of the recess and the lower edge of the protrusion of the squeezing body is formed into a small gap.

(Function) In the juicer of the present invention, the material to be cooked is inputted from the upper surface opening of the material input cylinder of the lid body, and the material to be cooked pushed by the push rod is placed in the rotating squeezing body. The material to be cooked is pressed against the cutter and cut by the cutter, and the material to be cooked that has been cut by the cutter is sent out to the outer circumference of the squeezer, and the material to be cooked is passed along the inner surface of the lid and between the outer circumference of the squeezer and the squeezer. The material to be cooked is compressed and pulverized by the spiral groove-shaped squeezing portion formed on the outer circumferential surface of the squeezing body, which is fed between the inner peripheral surface of the case and the juice squeezed from the material to be cooked. The juice is extracted from the juice outlet of the case while being filtered through a filter. Further, the residue of the material to be cooked is discharged from the residue discharge port of the squeezing case. Then, when the dregs that are not discharged from the dregs discharge section are sent to the outer bottom side of the squeezing body, the dregs are collected in a small area between the protrusion formed on the periphery of the outer bottom surface of the squeezing body and the inner bottom surface of the squeezing case. The gap prevents the dregs from entering the center, and the dregs that have passed through this gap enters the gap between the outer bottom surface of the squeezing body and the inner bottom surface of the squeezing case, which is wider than this gap, and the pressure against the dregs decreases. Continuous entry of debris is prevented.

Next, the operation of this embodiment will be explained.

Fit the squeeze case 28 into the outer case 10, fit the squeeze body 1 into the squeeze case 28, cover the lid 51 in this state, and engage the outer case locking protrusions 66 of the lid 51, respectively. The lid body 51 is locked by rotating with the fitting edge 65 fitted to the opening edge of the outer case 70 in the locking groove 71a of the stop portion 77, and the lid body 51 and the outer case 70 are connected to each other as a squeezing case. The squeezing case 28 is sandwiched between the outer case 70 and the lid 51, and the squeezing rest 1 is rotatable between the squeezing case 28 and the input cylinder part 52 of the lid 51. The juicer cooking device body 78 is constituted by the squeezing rest 1, the squeezing case 28, the lid body 51, and the outer case 70. This cooking device body 78 is fitted into the main body 79, and the cylindrical portion 72 of the outer case 70 is fitted into the fitting stepped portion 81 of the base portion 80.

The juicer cooking device body 78 is coupled to the main body 79 by engaging the main body locking protrusion 67 of the lid 51 with the locking groove 91a of the locking portion 91. In this state, the rotating shaft 31 connected to the rotating shaft connecting portion 26 of the squeeze rest 1 via the rotation transmitter 32 is connected to the drive shaft 8 through the engagement of the coupling 33.82.
3. Next, the juice container 87 is placed on the mounting portions 89 and 90 in front and behind the support portion 86 of the main body 79 and the base portion 80.
A combing container 88 is placed with the support section 86 and the stand section 80 interposed therebetween.

It is located with a very small gap. .

When the tip switch operation button 97 of the main body 79 is selectively operated, the electric motor 85 is driven and the squeezing body 1 is rotated. In this state, when the material to be cooked is charged through the input hole 53 of the lid body 51 and pressed by the push rod 68, the material to be cooked is cut by the cutter 20 at the inner bottom of the squeezing case 28. At this time, the cutter 20 has a vertical wall surface 24.17 at the bottom of the blade edge 23.
is formed, so that the cut pieces of the material to be cooked are not compressed and caught in the gap between the blade edge 23 and the inner bottom surface of the squeezing body 1, and furthermore, the cut pieces of the material to be cut next by the rotation of the cutter 20 are not compressed. It is pushed out in the outer circumferential direction at the straight wall surface 24°17 and can be cut even with a small cutting force. The cut pieces of the material to be cooked are cut by an annular glue 158 formed on the outer periphery of the lower surface of the input cylinder part 52 of the lid body 51, which surrounds the outer periphery of the cutter 20, and there is a gap between the upper surface of the cutter 20 and the bottom surface of the input cylinder part 52. A cutter 2 is formed on the bottom surface of the input cylinder 52 at a position including the final portion of the input hole 53 with respect to the rotating direction of the squeezing body 1.
A recessed step portion 57 is formed to increase the gap with 0, and an annular rib 58 is cut out in this portion, and a notch portion 59 is formed in the annular rib 58 at the position of the input hole 53. Cutting pieces such as large skin parts of the material to be cooked are retained at the bottom position of the input cylinder part 52 until they are cut into small pieces,
The small cut pieces are immediately sent out to the outside by the rotational centrifugal force of the squeezing body 1. The cut pieces of the material to be cooked that are sent out from the bottom position of the input cylinder 52 in this way are transferred to the input cylinder 52.
It is sent out into the gap between the outer circumferential surface of 2 and the inner circumferential surface of 1.

Since ribs 55 and 56 are formed on the outer circumferential surface of the input cylinder part 52, the cut pieces of the material to be cooked are suppressed from rotating as the squeezer body 1 rotates.
1 between! ! Since the gap is widened upward, the cut pieces of the material to be cooked are raised with little resistance. The cutting pieces fed to the upper end of the squeezer body 1 are guided from the protrusion 2 facing the inner surface of the lid body 51 with a small gap at the highest position of the squeezer body 1 to the cooking material introduction part 3 at a lower position. The squeeze body 1 is fed between the inner peripheral surface of the squeeze part case 28 and the spiral groove-shaped squeeze part 5 on the outer periphery by the centrifugal force of the rotation of the squeeze body 1. The cutting pieces fed into the squeezing part 5 descend while being crushed and compressed in the gap between them and the inner peripheral surface of the squeezing case 28, and the squeezed juice is transferred from the juice outlet part 37 of the squeezing case 28 to the filter 39. The filtered juice receiver in the outer case 70 flows out into the chamber 11. And squeeze case 2
Since the effective holes of the filter 39 of the juice outlet portion 37 of 8 are approximately flush with the inner bottom surface of the squeezing case 28, the squeezed juice is not retained inside the squeezing body 1. It will be leaked. In the juice receiver, the juice flowing out into the chamber 71 flows down into the juice container 87 from the juice outlet lower 1a.

And the lower end portion 10 of the spiral groove-shaped squeezing portion 5 of the squeezing body 1
The dregs discharge part 38 of the squeezing case 28 is located at a position that does not extend to the lower end of the squeezing body 1 but includes the final end 10 of the squeezing part 5. Since the groove-shaped portion 11 has an inclination that precedes the rotation of the squeezing chamber 36, when the draining valve 43 is opened, the portion of the material to be cooked is discharged from the draining section 38, and the squeezing chamber 36 is drained. Most of the soot is discharged from the dross discharge part 38 by the squeezer 5, and when the retained dross moves downward from the squeezer 5, it enters the spiral part 11, and the rotation of the squeezer 1 causes the grooved part 11 to pass through the dross discharge part. When reaching the position 38, the grooved portion 11
The dross that has entered expands, is pushed out by the dross discharge section 38, and is sent out to the dross discharge path 74. The dross that enters the groove-like portion 11 of the squeezing body 1 is difficult to enter because the lower tip is pushed against the rotating direction of the squeezing body 1. A notch 14 is formed in the strip 13 to prevent the dregs from entering the bottom side of the squeezing body 1. Roughly formed on the lower edge of the protruding strip 13 and on the outer circumferential side of the inner bottom surface of the squeezing case 28 There is a gap g2 lower than the height of the peel-off recess 35 between the inner bottom surface of the peel-off recess 35, and the pressure of the residue passing through this gap g2 is reduced in the scrap-prevention recess 35, and a rotating part is arranged to remove the residue. The waste discharge passage 74 does not enter the recess 29.
The waste discharged falls and is stored in a waste container 88.

Note that, as in the structure of the embodiment, the gap between the outer bottom surface of the squeezing body and the inner bottom surface of the squeezing case is larger than the gap between the inner bottom surface of the recess of the squeezing case and the lower edge of the protrusion of the squeezing body. By doing so, the dregs passing through the gap between the inner bottom surface of the squeezing case and the lower edge of the protrusion of the squeezing body is collected in the wide gap between the outer bottom surface of the squeezing body and the inner bottom surface of the squeezing case. The pressure against the sludge is reduced and the continuous draw of the sludge toward the center is prevented.

〔Effect of the invention〕

According to the present invention, a protrusion is formed on the periphery of the outer bottom surface of the squeezing body which has a squeezing portion opposing the inner surface of the squeezing case on its outer circumferential surface, and the protrusion is formed on the outer circumference of the inner bottom surface of the squeezing case. A recess is formed into which the squeezer enters, and a small gap is formed between the recess and the lower edge of the protrusion of the squeezing body, so that dregs do not enter between the outer bottom surface of the squeezing body and the squeezing case. This prevents the dregs from getting caught up in the rotating shaft, prevents the squeezing body from floating up, and prevents heat generation due to the intrusion of the dregs.
