Description

【０００１】
【発明の属する技術分野】
本発明は、果肉や繊維分の多いジュース、または果肉や繊維分の少ない比較的澄んだジュースを作ることができるジューサーに関する。
【０００２】
【従来の技術】
従来、材料の繊維を多く含んだジュースと、繊維を殆ど含まない澄んだジュースとを作るジューサーとして、特公昭57-11209号公報(A47J 19/00)に開示されるものがあった。
【０００３】
この従来技術を公報の符号を附して説明すると、このジューサーは、フィルター８の下方に他の孔７よりも大きな通孔27を形成し、この通孔27をカッタ台22に形成した開閉壁28にて開閉することにより、繊維分や果肉を含んだジュースや、繊維分や果肉を殆ど含まないジュースを好みに応じて生成するものであるが、フィルタ８の保持枠20に形成した挿入切欠21にカッタ台22に形成した脚部23を回り止め及び抜け止めして挿入しており、ジュースの濃度を切り換える際には、この保持枠20とカッタ台22とを一旦取り外して保持枠20を回転させて、再度カッタ台の脚部23と保持枠の挿入切欠21とを係合指せなければならず、使い勝手が悪い欠点があった。
【０００４】
このため、出願人は、特願平8-39976号にて、多数の孔を有する逆円錐状のフィルターを有する遠心分離籠の下方周面に、前記孔よりも大きな透孔を形成するとともに、フィルター外周にこの透孔を開閉する閉塞部を有するリング状部材を回転自在に配設し、このリング状部材をフィルターに対して回転させることにより、ジュースに混入する果肉及び繊維の量を調節してジュースの濃度を切り換えられるよう構成したものを提案した。
【０００５】
しかしながら、上記構成において、リング状部材を遠心分離籠の回転方向に対して両方向に回転可能な構成としているため、リング状部材の回転規制のクリックが弱い場合、リング状部材が遠心分離籠の回転時に慣性により回転する恐れがあるため、リング状部材の回転規制のクリック感を強くする必要がある反面、使用者がジュースの濃度を切り換える際に、このクリック感が強すぎると使用性が悪い問題がある。
【０００６】
また、一般的にジューサーのフィルターは、２枚の扇型の金属板の端部をスポット溶接にて接続して逆円錐形状に形成しているが、この接続部分に段差ができるために、フィルターとリング状部材との間隔が小さすぎる場合に、リング状部材をこの段差の端面に逆らう方向に回転させるとリング状部材がこの端面にて削られる恐れがあり、リング状部材による透孔の開閉の信頼性が低下することが考えられる。
【０００７】
【発明が解決しようとする課題】
本発明は上記欠点に鑑み成されたもので、ジュースの濃度を確実に切り換えできるとともに、透孔開閉の信頼性及び使用性を向上しえるジューサーを提供することを課題とする。
【０００８】
【課題を解決するための手段】
【０００９】
本発明は、電動機を内蔵する本体と、前記電動機により回転駆動されるカップリングと、前記本体上に載置される容器と、該容器の上面開口に取り付けられる蓋と、上面にカッターを有し前記電動機の回転軸のカップリングに連結されて回転するカッター台と該カッター台に取り付けられ周面に多数の孔を有するフィルターとを有する遠心分離籠と、前記フィルターの下方周面に形成され前記孔よりも径大な透孔と、前記フィルターに対して周方向に回転自在に配設され、フィルターの透孔を塞ぐ閉塞部を有するリング状部材とを備え、前記カッター台とリング状部材とに、前記リング状部材をフィルターに対して透孔を塞ぐ位置及び開放する位置において係止する係止部を各々形成し、前記カッター台の係止部の回転方向前方側と、前記リング状部材係止部の回転方向後方側とに各々垂直面を形成するとともに、前記カッター台の係止部の回転方向後方側に、リング状部材の係止部を案内する傾斜部を形成したことを特徴とするジューサー。
【００１０】
さらに、本発明は、電動機を内蔵する本体と、前記電動機により回転駆動されるカップリングと、前記本体上に載置される容器と、該容器の上面開口に取り付けられる蓋と、上面にカッターを有し前記電動機の回転軸のカップリングに連結されて回転するカッター台と該カッター台に取り付けられ周面に多数の孔を有するフィルターとを有する遠心分離籠と、前記フィルターの下方周面に形成され前記孔よりも径大な透孔と、前記フィルターに対して周方向に回転自在に配設され、フィルターの透孔を塞ぐ閉塞部を有するリング状部材とを備え、前記フィルターを、扇型のフィルター部材の端部を、遠心分離籠の回転方向後方側から前方側に向かって低くなる段部を形成するよう溶接し、前記カッター台とリング状部材とに、前記リング状部材をフィルターに対して透孔を塞ぐ位置及び開放する位置において係止する係止部を各々形成するとともに、前記リング状部材の遠心分離籠の回転方向後方側への回転を規制する規制手段を設けたことを特徴とする。
【００１１】
【発明の実施の形態】
本発明の実施の形態を図面に基づいて説明する。
【００１２】
１は図示しない電動機を内蔵する本体で、該本体１上面に前記電動機の回転軸２を突出させるとともに、該本体１の一側部にジュースカップ３を載置する載置部４を形成している。５は前記電動機の回転軸２に取り付けられたカップリングで、後述する遠心分離籠15のカッター台17と係合し、電動機の回転を遠心分離籠15に伝達するようになっている。
【００１３】
６は前記本体１に載置されるジュース容器で、底部に前記カップリング５が臨む開口７を形成するとともに、前記本体１の載置部４上方に対応する位置には、ジュースが流出する流出口８を形成している。
【００１４】
９は前記ジュース容器６に載置されるカス受け容器で、一側部にカス溜部10を形成するとともに、後述する遠心分離籠15が位置する開口部11を形成している。
【００１５】
12は前記ジュース容器６及びカス受け容器９の上面開口を開閉自在に被う蓋で、後述する遠心分離籠15のカッター16にて切削する材料を投入する投入筒13を一体形成しており、該投入筒13にプッシャー14を挿脱自在に配設している。
【００１６】
15は前記本体１と蓋12にて形成される空間内に配設される遠心分離籠で、前記カップリング５に係合し上面にカッター16を有するカッター台17と、該カッター台17に取り付けられ多数の長方形の孔を有するフィルター18とから構成されている。
【００１７】
前記フィルター18は、２枚の扇型のフィルター部材の端部をスポット溶接にて接続して逆円錐形に形成されており、この接続部に段部19が形成されるが、該段部19は、前記遠心分離籠15の回転方向後方側から前方側に向かって低くなるように溶接されている。
【００１８】
20は前記フィルター18の下方周面に形成された複数の透孔で、前記フィルター18の周面全体に形成された孔よりも径大に形成されており、後述するリング状部材24の閉塞部25により開閉自在に被われるようになっている。
【００１９】
21は前記カッター台17の外周部上面に全周にわたって形成された係合凸部で、後述するリング状部材24の突起29が係合し、リング状部材24を前記フィルター18に対して任意の位置に位置決めするようになっている。
【００２０】
前記係合凸部21は、図２及び図３に示す如く、前記カッター台17の回転方向前方側面に垂直な立壁部22を形成するとともにカッター台17の回転方向後方側面に傾斜部23を形成しており、後述するリング状部材24の突起29がカッター台17の回転方向前方側に回転する際には、突起29が傾斜部23に案内されて容易に回転するとともに、カッター台17の回転方向後方側(反回転方向)に回転するのを規制して、カッター台17の回転時に慣性によりリング状部材24が不用意に回転するのを確実に防止している。また、前記フィルター18の段部19に逆らう方向に回転するのを防止し、後述するリング状部材24の成型による寸法のバラツキ等によりリング状部材が段部19に接触した場合に、リング状部材24が削られるのを防止している。
【００２１】
24は前記遠心分離籠15のフィルター18外側に回転自在に配設されたリング状部材で、該リング状部材24の前記フィルター18の透孔20に対応する位置に、透孔20を被う閉塞部25を一体形成している。
【００２２】
26は前記閉塞部25の下端部に前記フィルター18に向かって形成された鍔部で、該鍔部26がフィルター18の外周下端部の傾斜部に当接することにより、前記リング状部材24の上方向への移動を規制し、リング状部材24の内周面及び閉塞部25内面とフィルター18との間にフィルター18周面の孔の最大幅よりも小さい隙間27を保持している。
【００２３】
前記隙間27の間隔をフィルター18の孔の最大幅よりも小さくすることにより、リング状部材24の閉塞部25によりフィルター18の透孔20を閉塞した状態で、フィルター18の孔から排出されるよりも大きな繊維分が透孔20からでようとしても隙間27に詰まるため、大きなカスが排出されることがない。
【００２４】
28は前記リング状部材24の閉塞部25下端部間を連結する連結環で、該連結環28により前記閉塞部25を連結することにより、前記遠心分離籠15の回転時に遠心力により閉塞部25が外周方向に撓むのを防止し隙間27が大きくなってカスが漏れるのを防止するとともに、リング状部材24の強度を向上できる。
【００２５】
29は前記閉塞部25及び連結環28下面に突出形成された突起で、前記カッター台17の係合凸部21に係合するとともに、前記係合凸部21を乗り越える際にクリック感を生じるようになっており、前記リング状部材24を回転方向前方側に向かって回転させて、リング状部材24の閉塞部25がフィルター18の透孔20を被う位置及び開放する位置に位置決めできるようになっている。
【００２６】
前記突起29の、カッター台17の係合凸部21の立壁部22に対向する側には、立壁部22に一致する垂直部30が形成されており、前記立壁部22に確実に当接してリング状部材24の遠心分離籠15の回転方向後方側への回転を規制し、遠心分離籠15の回転起動時にリング状部材24が不用意に回転するのを確実に防止するようになっている。
【００２７】
31は前記リング状部材24の外周部に形成された手掛用凸部で、前記リング状部材24を回転させる際に使用者の手指が引っ掛かりやすくすることにより、リング状部材24を回転させやすくしている。
【００２８】
前記リング状部材24の閉塞部25の幅は、前記フィルター18の透孔20の２倍以上で、且つ係合凸部21のピッチは閉塞部25の幅の１／２以下となっており、遠心分離籠15の形成時、カッター台17に対してフィルター18の透孔20がどの位置に於いて固定されても、(即ち、カッター台17に対してフィルター18の透孔20の位置がずれても)リング状部材24の閉塞部25により確実にフィルター18の透孔20が閉塞されるため、遠心分離籠15を形成する際にカッター台17とフィルター18とを位置決めすること無く固定でき、作業性を向上できるようになっている。
【００２９】
而して、果肉や繊維分の少ない比較的澄んだジュースを生成する際は、リング状部材24を回転させて閉塞部25によりフィルター18の透孔20を閉塞した状態で電動機を駆動させながら蓋12の投入筒13から材料を投入し、プッシャー14で押させると、遠心分離籠15下部のカッター16にて材料が切削されるとともに遠心力によりフィルター18の孔からジュース分が飛ばされ、ジュース容器６内に流れて流出口８から本体１に載置されたジュースカップ３に溜められる一方、ジュース分が絞られたカスは、遠心分離籠15のフィルター18内周面に沿って上方へ移動し、フィルター18の開口からカス受け容器９のカス溜部10内に放出される。
【００３０】
また、果肉や繊維分を含んだ濃いジュースを生成する際は、リング状部材24を回転させて閉塞部25によりフィルター18の透孔20を開放した状態で電動機を駆動させて使用する。この時、フィルター18の透孔20から切削物の果肉や繊維の一部がジュースとともに漏れてジュース容器９内に流れ、果肉や繊維分を含んだ濃いジュースを生成できる。
【００３１】
リング状部材24は、カッター台17の係合凸部21に立壁部22を形成したことにより、遠心分離籠15の回転方向後方側への回転が規制されるため、電動機の起動時に、リング状部材24がフィルター18に対して遠心分離籠15の反回転方向へ回転しようとする慣性力による不用意な回転を防止でき、確実にジュースの濃度を切り換えて生成できるとともに、リング状部材24とカッター台17とのクリック感を必要以上に強くする必要がなく、リング状部材24の回転操作性を低下させることがない。
【００３２】
さらに、遠心分離籠15の回転方向後方側から前方側に向かって低くなるように溶接されて段部19が形成されているとともに、係合凸部21に立壁部22を形成してリング状部材24の回転方向後方側への回転が規制されているため、リング状部材24の成型時の寸法誤差等によりリング状部材24がフィルター18に接触しても、リング状部材24の閉塞部25が段部19により削られるのを防止して、リング状部材24の閉塞部25とフィルター18の透孔20との間隔が広がって必要以上の果肉や繊維分が混入するのを防止でき、信頼性を向上できる。
【００３３】
【発明の効果】
【００３４】
本発明の請求項１によると、カッター台とリング状部材に形成した係止部の相対向する垂直面が当接することにより、電動機の起動時に遠心分離籠の回転に伴う反作用によりリング状部材が遠心分離籠の反回転方向に回転するのを確実に防止でき、リング状部材とフィルターとの係合のクリック感を強くすることなくリング状部材が不用意に回転するのを防止してジュースの濃度の切り換えを確実に行うことができ、リング状部材を容易に回転させることができ使用性を向上できる。
【００３５】
さらに、本発明の請求項２によると、電動機の起動時に遠心分離籠の回転に伴う反作用によりリング状部材が遠心分離籠の反回転方向に回転するのを防止でき、リング状部材が不用意に回転するのを防止することによりジュースの濃度の切り換えを確実に行うことができるとともに、リング状部材を遠心分離籠の回転方向後方側、即ちフィルターの接続部の段部に逆らう方向に回転するのを規制することにより、リング状部材の成型時の寸法誤差等によりリング状部材の閉塞部とフィルターとの間隔が狭くなった場合でも、リング状部材がフィルターの段部により削られることがなく、ジュース濃度切り換えの信頼性を向上できる。

BACKGROUND OF THE INVENTION
The present invention relates to a juicer that can produce juice with a high pulp content and fiber content, or a relatively clear juice with a low content of pulp and fiber content.
[0002]
[Prior art]
Conventionally, as a juicer for producing a juice containing a large amount of material fiber and a clear juice containing almost no fiber, Japanese Patent Publication No. 57-11209 (A47J 19/00) has been disclosed.
[0003]
This prior art will be described with reference to the gazette. This juicer has an opening / closing wall in which a through hole 27 larger than the other hole 7 is formed below the filter 8 and the through hole 27 is formed in the cutter base 22. By opening and closing at 28, juice containing fiber and pulp or juice containing almost no fiber and pulp is produced according to preference, but the insertion notch formed in the holding frame 20 of the filter 8 The leg 23 formed on the cutter base 22 is inserted into the base 21 in a non-rotating and retaining manner.When switching the juice concentration, the holding frame 20 and the cutter base 22 are temporarily removed and the holding frame 20 is removed. The cutter base leg 23 and the insertion notch 21 of the holding frame have to be engaged again with each other, and there is a disadvantage that the usability is poor.
[0004]
Therefore, the applicant, in Japanese Patent Application No. 8-39976, on the lower peripheral surface of the centrifugal separator having an inverted conical filter having a large number of holes, a through-hole larger than the hole is formed, A ring-shaped member having a blocking portion that opens and closes the through hole on the outer periphery of the filter is rotatably disposed, and the amount of pulp and fibers mixed in the juice is adjusted by rotating the ring-shaped member with respect to the filter. The juice was designed to change the juice concentration.
[0005]
However, in the above configuration, since the ring-shaped member is configured to be rotatable in both directions with respect to the rotation direction of the centrifugal separator, the ring-shaped member is rotated by the centrifugal separator when the rotation restriction of the ring-shaped member is weak. Since it may rotate due to inertia at times, it is necessary to increase the click feeling of the rotation restriction of the ring-shaped member, but when the user switches the juice concentration, if the click feeling is too strong, the usability is poor There is.
[0006]
In general, a juicer filter is formed in an inverted conical shape by connecting the ends of two fan-shaped metal plates by spot welding. If the distance between the ring member and the ring member is too small, the ring member may be scraped at the end face if the ring member is rotated in a direction opposite to the end face of the step. It is conceivable that the reliability of the system is lowered.
[0007]
[Problems to be solved by the invention]
The present invention has been made in view of the above-mentioned drawbacks, and an object thereof is to provide a juicer capable of reliably switching the concentration of juice and improving the reliability and usability of opening and closing of the through holes.
[0008]

[0011]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings.
[0012]
Reference numeral 1 denotes a main body containing an electric motor (not shown). The main shaft 1 has a rotating shaft 2 protruding on the upper surface of the main body 1 and a mounting portion 4 on which a juice cup 3 is mounted on one side of the main body 1. Yes. Reference numeral 5 denotes a coupling attached to the rotary shaft 2 of the electric motor, which is engaged with a cutter base 17 of a centrifugal separator 15 described later, and transmits the rotation of the electric motor to the centrifugal separator 15.
[0013]
Reference numeral 6 denotes a juice container placed on the main body 1, and an opening 7 facing the coupling 5 is formed at the bottom, and the juice flows out at a position corresponding to the upper portion of the placement part 4 of the main body 1. An outlet 8 is formed.
[0014]
Reference numeral 9 denotes a waste receiving container placed on the juice container 6, which forms a residue reservoir 10 on one side and an opening 11 in which a centrifugal separator 15 described later is located.
[0015]
12 is a lid that covers the upper surface openings of the juice container 6 and the waste container 9 so as to be openable and closable, and is integrally formed with an input cylinder 13 for supplying a material to be cut by a cutter 16 of a centrifugal separator 15 described later. A pusher 14 is detachably disposed in the charging cylinder 13.
[0016]
Reference numeral 15 denotes a centrifugal separator disposed in a space formed by the main body 1 and the lid 12, and a cutter base 17 that engages with the coupling 5 and has a cutter 16 on the upper surface, and is attached to the cutter base 17. And a filter 18 having a number of rectangular holes.
[0017]
The filter 18 is formed in an inverted conical shape by connecting the end portions of two fan-shaped filter members by spot welding, and a step portion 19 is formed at the connection portion. Are welded so as to be lowered from the rear side in the rotational direction of the centrifugal separator 15 toward the front side.
[0018]
Reference numeral 20 denotes a plurality of through holes formed in the lower peripheral surface of the filter 18, which are formed larger in diameter than holes formed in the entire peripheral surface of the filter 18, and are closed portions of a ring-shaped member 24 described later. It can be opened and closed by 25.
[0019]
21 is an engagement convex portion formed on the upper surface of the outer peripheral portion of the cutter base 17 over the entire circumference, and a projection 29 of a ring-shaped member 24 to be described later is engaged with the ring-shaped member 24 with respect to the filter 18. It is designed to be positioned.
[0020]
As shown in FIGS. 2 and 3, the engaging convex portion 21 forms an upright wall portion 22 perpendicular to the front side surface in the rotational direction of the cutter table 17 and forms an inclined portion 23 on the rear side surface in the rotational direction of the cutter table 17. When the projection 29 of the ring-shaped member 24, which will be described later, rotates forward in the rotational direction of the cutter table 17, the projection 29 is easily guided by the inclined portion 23 and rotates. By restricting rotation in the rearward direction (counter-rotation direction), the ring-shaped member 24 is reliably prevented from rotating carelessly due to inertia when the cutter base 17 rotates. Further, when the ring-shaped member is prevented from rotating in the direction opposite to the stepped portion 19 of the filter 18 and the ring-shaped member comes into contact with the stepped portion 19 due to dimensional variation due to molding of the ring-shaped member 24 described later, the ring-shaped member 24 is prevented from being cut.
[0021]
24 is a ring-shaped member rotatably disposed outside the filter 18 of the centrifugal separator 15, and the ring-shaped member 24 is closed to cover the through-hole 20 at a position corresponding to the through-hole 20 of the filter 18. The part 25 is integrally formed.
[0022]
26 is a flange formed at the lower end portion of the closed portion 25 toward the filter 18, and the upper portion of the ring-shaped member 24 is brought into contact with the inclined portion at the lower end of the outer periphery of the filter 18. The movement in the direction is restricted, and a gap 27 smaller than the maximum width of the hole on the peripheral surface of the filter 18 is held between the inner peripheral surface of the ring-shaped member 24 and the inner surface of the closed portion 25 and the filter 18.
[0023]
By making the gap 27 smaller than the maximum width of the hole of the filter 18, the through hole 20 of the filter 18 is closed by the closing part 25 of the ring-shaped member 24, and the filter 18 is discharged from the hole of the filter 18. However, even if a large amount of fiber comes out of the through-hole 20, the gap 27 is clogged, so that no large waste is discharged.
[0024]
28 is a connecting ring for connecting the lower end portions of the closed portion 25 of the ring-shaped member 24. By connecting the closed portion 25 by the connecting ring 28, the closed portion 25 is caused by centrifugal force when the centrifugal separator 15 is rotated. Can be prevented from bending in the outer circumferential direction, and the gap 27 can be increased to prevent leakage of the residue, and the strength of the ring-shaped member 24 can be improved.
[0025]
29 is a protrusion formed on the lower surface of the closing portion 25 and the connecting ring 28 so as to engage with the engaging convex portion 21 of the cutter table 17 and generate a click feeling when getting over the engaging convex portion 21. The ring-shaped member 24 is rotated toward the front side in the rotation direction so that the closed portion 25 of the ring-shaped member 24 can be positioned at a position where the filter 18 has the through-hole 20 and an open position. It has become.
[0026]
On the side of the projection 29 facing the upright wall portion 22 of the engagement convex portion 21 of the cutter base 17, a vertical portion 30 that coincides with the upright wall portion 22 is formed, and is surely in contact with the upright wall portion 22. The rotation of the ring-shaped member 24 to the rear side in the rotation direction of the centrifugal separator 15 is restricted, and the ring-shaped member 24 is reliably prevented from rotating carelessly when the centrifugal separator 15 is rotated. .
[0027]
31 is a hand-convex convex portion formed on the outer peripheral portion of the ring-shaped member 24. When the ring-shaped member 24 is rotated, the user's fingers are easily caught so that the ring-shaped member 24 can be easily rotated. is doing.
[0028]
The width of the closed portion 25 of the ring-shaped member 24 is at least twice that of the through hole 20 of the filter 18, and the pitch of the engaging convex portions 21 is 1/2 or less of the width of the closed portion 25, When the centrifuge 15 is formed, the position of the through hole 20 of the filter 18 relative to the cutter base 17 is fixed (that is, the position of the through hole 20 of the filter 18 is shifted relative to the cutter base 17). Even if) the through-hole 20 of the filter 18 is reliably closed by the closing part 25 of the ring-shaped member 24, it can be fixed without positioning the cutter base 17 and the filter 18 when forming the centrifugal separator 15, Workability can be improved.

Thus, when producing a relatively clear juice with a small amount of pulp and fiber, the ring-shaped member 24 is rotated and the electric motor is driven while the through hole 20 of the filter 18 is closed by the closing portion 25 while the lid is driven. When the material is charged from the 12 charging cylinders 13 and pushed by the pusher 14, the material is cut by the cutter 16 at the bottom of the centrifugal separator 15 and the juice is blown from the hole of the filter 18 by the centrifugal force. 6, which flows into the juice cup 3 placed in the main body 1 from the outlet 8, while the juice that has been squeezed is moved upward along the inner peripheral surface of the filter 18 of the centrifugal separator 15. Then, it is discharged from the opening of the filter 18 into the residue reservoir 10 of the residue receptacle 9.
[0030]
Further, when producing a thick juice containing pulp and fiber, the motor is driven while the ring-shaped member 24 is rotated and the through hole 20 of the filter 18 is opened by the closing portion 25. At this time, a part of the pulp and fibers of the cut material leaks together with the juice from the through-hole 20 of the filter 18 and flows into the juice container 9, and a thick juice containing the pulp and fibers can be generated.
[0031]
Since the ring-shaped member 24 is formed with the standing wall portion 22 on the engagement convex portion 21 of the cutter base 17, the rotation of the centrifugal separator 15 to the rear side in the rotation direction is restricted. The member 24 can prevent inadvertent rotation due to the inertial force that tries to rotate the centrifuge 15 in the counter-rotating direction with respect to the filter 18, and can be generated by switching the concentration of the juice, and the ring-shaped member 24 and the cutter It is not necessary to make the click feeling with the base 17 stronger than necessary, and the rotational operability of the ring-shaped member 24 is not lowered.
[0032]
Further, a step portion 19 is formed by being welded so as to be lowered from the rear side to the front side in the rotation direction of the centrifugal separator 15, and a standing wall portion 22 is formed on the engaging convex portion 21 to form a ring-shaped member. Since the rotation of the ring-shaped member 24 to the rear side is restricted, even if the ring-shaped member 24 comes into contact with the filter 18 due to a dimensional error during molding of the ring-shaped member 24, the closed portion 25 of the ring-shaped member 24 It can be prevented from being scraped by the stepped portion 19, and the gap between the closed portion 25 of the ring-shaped member 24 and the through-hole 20 of the filter 18 can be widened to prevent more pulp and fibers from being mixed than necessary. Can be improved.

【The invention's effect】
[0034]
According to the first aspect of the present invention, the opposing vertical surfaces of the locking portions formed on the cutter base and the ring-shaped member come into contact with each other, so that the ring-shaped member is caused by the reaction caused by the rotation of the centrifugal separator when the electric motor is started. It is possible to reliably prevent the centrifuge from rotating in the counter-rotating direction, preventing the ring-shaped member from rotating carelessly without increasing the click feeling of the engagement between the ring-shaped member and the filter. The concentration can be switched reliably, the ring-shaped member can be easily rotated, and the usability can be improved.
[0035]
Furthermore, according to claim 2 of the present invention, the ring-shaped member can be prevented from rotating in the counter-rotating direction of the centrifugal separator due to the reaction accompanying the rotation of the centrifugal separator when the electric motor is started, and the ring-shaped member is inadvertently By preventing the rotation, the juice concentration can be switched reliably, and the ring-shaped member is rotated backward in the direction of rotation of the centrifuge bowl, that is, in a direction against the stepped portion of the filter connecting portion. By regulating the ring-shaped member, even when the gap between the closed portion of the ring-shaped member and the filter becomes narrow due to a dimensional error during molding of the ring-shaped member, the ring-shaped member is not scraped by the step portion of the filter, The reliability of juice concentration switching can be improved.
