Description

【0001】
【産業上の利用分野】
この発明は、野菜や果物などの食品材料を細かく裁断するだけでなく、氷を砕いてきめ細かいかき氷を作ったりコーヒー豆などを粉砕するのにも好適なミキサーと、このミキサーに用いるカッタとに関するものである。
【0002】
【従来の技術】
野菜や果物などの食材を水や牛乳などと共に容器に入れ、略二枚羽根状のカッタを高速回転させることによって細かく裁断し、ジュースにするミキサーが広く用いられている。またコーヒー豆などを細かくすり砕いて粉にするコーヒーミルと呼ばれる一種のミキサーも広く用いられている。さらにジュースなどと共に入れた氷を細かく砕いてかき氷状の飲み物にするためにもミキサーが用いられている。
【0003】
従来広く用いられているミキサーは主として野菜や果物を裁断して液体状にするのに都合が良く作られている。この場合カッタは食材を液体と共に撹拌対流させるものであり、両端を斜上外側へ起立させ、この起立部に設けた刃先の向きを、回転軸の軸方向から見てカッタの回転軌跡に対して外径方向あるいはほぼ接線方向となるようにしていた。
【0004】
すなわち起立部の内側面を回転軌跡円に対して接線方向とした場合に、刃先はこれら内側面と円との交点よりも通常回転方向側に偏位しているため、刃先は回転軌跡よりも外径方向を指向することになるものである。また刃先が内径側から見て先端に向かって反回転方向へ後退している場合には、刃先の向きは先端に接近するのに伴って次第に接線方向に接近することになる。
【0005】
しかしこのカッタで硬い氷や硬いコーヒー豆などを砕く場合には、刃が氷や豆をはじき飛ばして食材の対流が乱れることになる。このためきめ細かいかき氷を作ったりコーヒー豆を均一な粒径に砕くことが困難である。またカッタの回転に伴い食材も回転するので、食材に遠心力が加わり、食材がカッタの付近で径方向外側へ流動する。この時食材が硬い氷や豆類であると、氷や豆はカッタの側面に衝突することになって刃に当たらずにはじき飛ばされることが多くなる。このためかき氷の製造や豆の粉砕に時間がかかり、粒径が揃ったなめらかなかき氷やコーヒー粉末を得ることが困難であった。
【0006】
そこで氷が遠心力によって径方向外側に流動する際に氷が刃に当たり易くするため、板状のカッタの回転軌跡に対する傾きを適切にすることが提案されている(例えば、特許文献1、2参照)。これらの既提案のものは、刃先の回転軌跡を反回転方向側の端面の回転軌跡より回転中心側に位置させたものであった。すなわち板状カッタの刃先を内径側に偏位させたものであった。

【特許文献2】
特開平10−192159号公報
【0008】
【発明が解決しようとする課題】
このような既提案のカッタにおいては、刃先と反回転方向側の端面との間に平板状の側面が存在するため、遠心力により流動する氷の一部は刃に当たらずにこの側面に直接衝突してはね飛ばされるのを避けることはできない。このためかき氷の製造時間の短縮が困難であり、均一粒径の滑らかなかき氷の製造が依然として困難であった。同様な問題は、コーヒー豆などの硬い食材を粉砕する場合にも生じるものであった。
【0009】
この発明はこのような事情に鑑みなされたものであり、野菜や果物の粉砕は勿論可能であるが、特に氷やコーヒー豆などの硬い食材を能率よくかつ均一な粒径に細かく粉砕するのに適し、かき氷を作る場合には滑らかでクリーミーなものを簡単に作ることが可能なミキサーを提供することを第1の目的とする。またこのミキサーに使用するカッタを提供することを第2の目的とする。
【0010】
【発明の構成】
この発明によれば第1の目的は、食材を収容する着脱可能な容器の内底部中央付近から起立する回転軸に、長手方向外側部分に斜上外側に向って立ち上がる起立部を有するカッタを固定したミキサーにおいて、前記起立部には前記カッタの長手方向に長くその先端および内径側に向って開く長溝が形成され、前記起立部の回転方向および反回転方向の内径側角部を刃としたことを特徴とするミキサー、により達成される。
【0011】
また第2の目的は、着脱可能な容器の中に収容した食材を裁断するミキサーに用いられ、長手方向外側部分に斜上外側に向って立ち上がる起立部を有するカッタにおいて、前記起立部にその長手方向に長くその先端および内径側に向って開く長溝が形成され、前記起立部の回転方向および反回転方向の内径側角部を刃としたことを特徴とするミキサー用カッタ、により達成される。
【0012】
【作用】
カッタの回転により容器内の食材も同方向に回転する。この回転により食材には遠心力が発生し、食材は径方向外側へ流動する。この時食材はカッタの起立部に設けた回転方向および反回転方向の2つの内径側角部に衝突し、ここで裁断(カット)されまた破砕される。
【0013】
カッタに当たった食材は、起立部の長溝によって回転方向または反回転方向の移動が制限されつつ斜上外側に流動する。すなわち従来の板状のカッタのようにカッタの側面に当たった食材がそのまま内径側にはね飛ばされるのではなく、長溝により斜上に導かれる。このため容器内壁に沿って上昇する強い流動が形成され、食材が効率良くかつ円滑にカッタの中央へ流れ込む。この結果食材の処理時間を短縮でき、粒径の均一化が可能になる。
【0014】
【実施態様】
図1は本発明の一実施態様の分解斜視図、図2はカッタを取付けた容器台の拡大斜視図、図3はその分解斜視図、図4はカッタの平面図、図5はカッタの側面図、図6は食材の流れを説明する図、図7はカッタの機能を説明する概念図である。
【0015】
図1において符号10は略円柱状のミキサー本体部であり、電動モータ(図示せず)などを内蔵する。このミキサー本体部10の上面には平面視円形のカップリングギヤ収容部12が形成されている。このカップリングギヤ収容部12の中央にはモータの回転軸(図示せず)が垂直に突出し、ここにカップリングギヤの駆動側(図示せず)が固定されている。
【0016】
14は略有底円筒状の容器台である。容器台14にはその中央を回転軸16が上下に貫通している。この回転軸16の下端にはカップリングギヤの被動側18が固定される一方、その上端には略板状の下カッタ20および略板状の上カッタ22が固定されている。上カッタ22は本発明のカッタとなるものであり、その構成は後記する。容器台14はミキサー本体部10のカップリングギヤ収容部12に上方から係入可能であり、この係入時にカップリングギヤの被動側18がミキサー本体部10の駆動側に係合する。
【0017】
24は食材を収容する略逆コップ状の容器である。この容器24は上端が閉じた略円錐状であり、その下端外周を容器台14に上方から螺合可能である。従ってこの容器24を容器台14に螺着した状態では、容器の内底部中央に回転軸16の上端が起立することになる。
【0018】
26はこの容器24に上方から被冠可能なキャップである。このキャップ26は容器24よりやや大きい略逆コップ状である。容器24を容器台14に螺着し、容器台14をミキサー本体部10のカップリングギヤ収容部12に装着した状態で、このキャップ26を容器24に被せる。そしてキャップ26を強く押下すればモータのスイッチがオンになるように構成されている。
【0019】
すなわちキャップ26に設けた舌部28は、ミキサー本体部10の上部外周に設けた係合凹部30に係合可能であり、両者を位置合せしつつキャップ26を強く押下すれば、キャップ26の下縁(開口縁)に設けた突起(図示せず)がミキサー本体部10の上縁(開口縁)に設けた係入孔32に進入する。この結果モータのスイッチがオンになる。またキャップ26の押下力を弱めれば、キャップ26は図示しないばねの復帰力によってモータ本体部10から僅かに浮き上がり、これと同時にモータのスイッチがオフになる。
【0020】
次に上カッタ22を説明する。この上カッタ22は図4,5に示すように、長細い金属板の両端を次第に幅を狭く加工して斜上外側方へ折曲した略板状のものであり、左右対称な略二枚羽根状(あるいは回転羽根状)である。その中央には回転軸16が係入する取付孔34を有する水平部36を持ち、この水平部36の両側に連続して斜上外側へのびる中間部38および起立部40を持つ。
【0021】
起立部40は先端に向って次第に幅が狭くなるなると共に、回転軸16(が通る取付孔34)を通りかつ上カッタ22の長手方向の直線Aに沿ってこの直線Aの両側を内側へ折曲した断面略V字状である。すなわち上カッタ22の長手方向の直線Aに直交する断面が略V字形である。この結果起立部40には、直線Aに沿って長くかつ先端41および内径側(回転軸16側)に向って開いた長溝42が形成される。
【0022】
この上カッタ22はステンレス鋼などの厚板を切断し、折曲することにより形成することができる。すなわち長手方向の直線Aに直交する面での断面形状が長四角形の素材をプレス加工することにより中間部38および起立部40を加工すればよい。
【0023】
図7はこの上カッタ22の断面、すなわち起立部40の長溝42の長手方向に対する直交断面を示している。ここで起立部40の回転方向(矢印F方向)の内径側角部44および反回転方向の内径側角部46には刃が形成されている。この刃は切削・焼込れにより形成してもよいが、剪断加工した加工面をそのまま刃として利用してもよい。
【0024】
これらの内径側角部44,46の刃には、遠心力によって外径方向Bに流動する食材が当たってカットされる。あるいは砕かれる。この時食材は起立部40の長溝42に導かれて斜上外側へ送られる。このため食材は内径側角部44,46上を滑りながら移動することになり、食材のカットは一層円滑に行われる。
【0025】
この実施態様の上カッタ22を、前記したように断面長方形の厚板を剪断・プレス加工で作成した場合には、内径側角部44,46および外径側角部48,50はそれぞれ略直角の断面形状となる(図7参照)。このためこれら角部44,46,48,50を挟む2つの面(V字形の谷の一方の面42aと、起立部40の幅方向の端面52)の2等分線が、食材が遠心力で移動する方向(B)にほぼ一致することになり、食材のカットや破砕が円滑に行われる。
【0026】
またこの実施態様では、回転方向(F)の外径側角部48が内径側角部44よりも回転方向(F)に前進している。この外径側角部48にも前記内径側角部44と同様に刃を形成しておき、この角部48を挟む2つの面の2等分線が、上カッタ22がその回転により食材に当たる方向(C)にほぼ一致させれば、外径側角部48がカッタ22の回転により食材を円滑にカットしかつ破砕することができる。
【0027】
このようにこの実施態様によれば、遠心力で移動する食材を内径側角部44,46でカットし、カッタ22の回転によって食材を外径側角部48でカットするから、結局刃の数が複数になったことになり、上カッタ22の耐久性を向上させ切れ味を良くすることができる。
【0028】
以上の説明からも理解できるように、この上カッタ22を使えば、図6に矢印で示すように、食材は起立部40によって容器24の内壁に沿って押し上げられ、中央付近から上カッタ22の中央付近に落下するように流動する。そして食材は遠心力により起立部40の2つの内径側角部44,46でカット・破砕される。また上カッタ22の回転により回転方向の外径側角部48が食材に当たって、食材をさらにカット・破砕することができる。さらに起立部40は長溝42の加工によって剛性が増大し、カッタ22の強度も向上する。
【0029】
【他の実施態様】
図8,9,10は他の実施態様であるカッタ22Aを示す平面図と、側面図と、斜視図である。このカッタ22Aは、前記図4,5に示した上カッタ(カッタ)22に対して、中間部38を省いたものである。
【0030】
この実施態様によれば、断面V字形の長溝42Aが前記図4,5に示したものに比べて、長手方向に長くなるから、食材をこの長溝42Aに効率良く捕捉して斜上外側へ送ることができる。また刃となる部分、すなわち図7における内径側角部44,46や外径側角部48などに相当する部分が長くなるので、食材をカットし破砕する能力も向上する。
【0031】
【他の実施態様】
図11に示すカッタ22Bは、起立部40Bの断面形状を略W字形にして長溝42Bを二列にしたものである。この実施態様によれば、回転方向および反回転方向の内径側角部44B,46Bの間にさらに中間角部54を形成することができ、ここを刃とすることによりカッタの破砕力あるいは切れ味は一層向上する。すなわち遠心力で流動する食材は3つの角部44B,46B,54の刃でカットされ破砕されるからである。
【0032】
なお前記図4,5,8〜10に示したカッタ22,22Aでは、断面が略V字形であるからカッタの剛性が増大し、強度が増大するが、この図11に示すカッタ22Bではさらに剛性が増大し、硬い食材のカットに一層適するものとなる。
【0033】
【他の実施態様】
図12はカッタ22Cの起立部40Cの断面形状を、略U字状にしたものである。この実施態様によれば長溝42Cに食材を多く保持して斜上外側へ円滑に送ることができる。すなわち食材の移送量を増やして図6に示した縦方向の流動を強化する。この結果食材のカット・破砕を一層円滑に行うことが可能になる。
【0034】
【他の実施態様】
図13に示す起立部40Dは、長溝42Dの断面形状を略L字形として、長溝42Dの谷底を通る直線を挟んで非対称にしたものである。この起立部40Dを有するカッタ22Dを用いる場合に、長溝42Dの谷を挟む長辺42dが回転方向(F)側に位置させれば、カッタ22Dの回転時に長溝42Dによって斜上外側に導かれる食材が反回転方向側の短辺に保持され易くなり、斜上外側への移動が一層円滑に行われる。
【0035】
【他の実施態様】
図14に示すカッタ22Eは、起立部40Eの内径側角部44E,46Eを鋭角としたものである。また外径側角部48E,50Eを内径側角部44E,46Eよりもそれぞれ反回転方向および回転方向(F)に偏位させたものである。この実施態様によれば、内径側角部44E,46Eの刃が鋭くなり、食材をカットする能力、特に野菜などの軟らかい食材をカットする能力が向上する。
【0036】
以上の図7,8,13,14に示すカッタ22,22A,22D,22Eでは、長溝42,42A,42D,42Eの谷を通る直線(図7,8,13,14における直線A)が、カッタの回転中心を通るようにしたが、この直線を回転中心から偏位させてもよい。この谷を通る直線は回転中心を通る直線Aと平行にするのが望ましいが、回転中心を通る直線Aに対して傾けてもよい。
【0037】
例えばこの谷を通る直線はカッタの内径側に比べて外径側を反回転方向に偏位させるように傾ければ、カッタの回転に伴う食材の外径方向への移動方向に長溝の方向を揃える(あるいは接近させる)ことができ、食材の長溝内での流動を一層円滑化することができる。このため内径側角部での食材のカット・破砕が一層円滑になる。
【0038】
また起立部は以上の実施態様ではカッタの長手方向の両側に設けているが、本発明はカッタの長手方向の一方だけに本願発明に係る起立部を設けたものであってもよい。この場合他方を下方へ折曲して、回転軸回りの重量バランスをとるのが望ましい。
【0039】
また起立部に設ける長溝は、先端に向かって次第に浅くするのがよい。遠心力により内径側角部でカットされ破砕された食材を、この長溝に捕捉して先端に移動した後、長溝から円滑に放出し易くなるからである。なおこのように長溝を先端に向かって次第に浅くするためには、起立部の幅(長手方向にほぼ直交する方向の幅)を先端に向かって次第に狭くする方法と、長溝の谷を挟む2辺の角度を先端に向かって次第に大きくする方法と、これら2つの方法を組合せた方法が採用可能である。
【0040】
【発明の効果】
請求項1〜8の発明によれば、カッタの長手方向の外側部分に設けた起立部に、その長手方向に長くその先端および内径側に開く長溝を形成し、回転方向および反回転方向の内径側角部を刃としたものであるから、食材がカッタに追従して回転することにより食材に作用する遠心力が食材を内径側角部に強く衝突させる。この時食材は長溝に導かれて斜上外側へ移動する。このため食材は内径側角部に接触しつつ移動するから食材は円滑にカットされ、また破砕され得る。
【0041】
内径側角部は起立部の少くとも回転方向および反回転方向にできるので、食材は少くとも2ヶ所でカット・破砕されることになる。このため従来のカッタに比べて処理速度が上がり、短時間で処理することが可能になる。また食材は長溝によって縦方向に強く円滑に流動するから、カット・破砕が能率よく行えることになり、粒径の揃ったかき氷や粉体を得ることができる。さらにカッタは長溝を加工することによりその剛性が増大し、硬い食材の処理に適するものとなる。
【0042】
請求項9の発明によれば、請求項1〜8のいずれかのミキサーに使用する部品であるカッタが得られる。

[Industrial applications]
The present invention relates to a mixer suitable not only for finely cutting food materials such as vegetables and fruits, but also for crushing ice to produce fine shaved ice and crushing coffee beans and the like, and a cutter used for the mixer. It is.
[0002]
[Prior art]
2. Description of the Related Art Mixers for putting juice such as vegetables and fruits into a container together with water, milk, and the like, and cutting the cut into fine pieces by rotating a substantially two-bladed cutter at high speed are widely used. Also, a kind of mixer called a coffee mill, which grinds coffee beans or the like into fine powder, is widely used. In addition, a mixer is used to crush the ice put together with the juice and the like into a shaved ice-like drink.
[0003]
Conventionally, widely used mixers are conveniently made mainly for cutting vegetables and fruits into liquids. In this case, the cutter agitates and convects the food material together with the liquid, and raises both ends obliquely upward and outward. The outer diameter direction or almost tangential direction was set.
[0004]
That is, when the inner surface of the upright portion is tangential to the rotation locus circle, the cutting edge is deviated in the normal rotation direction from the intersection of the inner surface and the circle, so the cutting edge is more than the rotation locus. It is directed in the outer diameter direction. When the cutting edge is retracted in the anti-rotation direction toward the tip when viewed from the inner diameter side, the orientation of the cutting edge gradually approaches the tangential direction as approaching the tip.
[0005]
However, when crushing hard ice or hard coffee beans with this cutter, the blade repels the ice or beans and disrupts the convection of food. For this reason, it is difficult to make fine shaved ice or to crush coffee beans to a uniform particle size. Further, since the food material also rotates with the rotation of the cutter, centrifugal force is applied to the food material, and the food material flows radially outward near the cutter. At this time, if the food is hard ice or beans, the ice or beans often strike the side of the cutter and are repelled without hitting the blade. For this reason, it takes time to produce shaved ice and pulverize beans, and it is difficult to obtain smooth shaved ice or coffee powder having a uniform particle size.
[0006]
Therefore, it has been proposed to make the inclination of the plate-shaped cutter with respect to the rotation locus appropriate so that the ice easily hits the blade when the ice flows radially outward due to centrifugal force (for example, see Patent Documents 1 and 2). ). In these existing proposals, the rotation trajectory of the cutting edge is positioned closer to the rotation center than the rotation trajectory of the end face on the anti-rotation direction side. That is, the blade edge of the plate-shaped cutter was deviated toward the inner diameter side.
[0007]
[Patent Document 1]
Japanese Patent No. 2865338 [Patent Document 2]
Japanese Patent Application Laid-Open No. 10-192159
[Problems to be solved by the invention]
In such a proposed cutter, since a flat side surface exists between the blade edge and the end surface on the side opposite to the rotation direction, part of the ice flowing due to centrifugal force directly hits this side surface without hitting the blade. You cannot avoid being hit by a collision. For this reason, it was difficult to shorten the manufacturing time of shaved ice, and it was still difficult to manufacture smooth shaved ice having a uniform particle size. A similar problem occurred when grinding hard foodstuffs such as coffee beans.
[0009]
The present invention has been made in view of such circumstances, and it is of course possible to grind vegetables and fruits, but it is particularly suitable for efficiently grinding hard food materials such as ice and coffee beans into fine particles of uniform size. It is a first object of the present invention to provide a mixer which is suitable and can easily produce a smooth and creamy one when shaved ice is made. A second object of the present invention is to provide a cutter for use in the mixer.
[0010]
Configuration of the Invention
According to the present invention, a first object is to fix a cutter having an upright portion that rises obliquely outward at a longitudinally outer portion on a rotating shaft that rises from near the center of an inner bottom portion of a detachable container that stores foodstuffs. In the mixer, the upright portion is formed with a long groove that is long in the longitudinal direction of the cutter and opens toward the distal end and the inner diameter side, and the inner diameter side corners in the rotation direction and the anti-rotation direction of the upright portion are blades. Is achieved by a mixer.
[0011]
A second object is a cutter used for a mixer for cutting foodstuffs housed in a detachable container, the cutter having an upright portion that rises obliquely outward at a longitudinally outer portion. The present invention is achieved by a mixer cutter in which a long groove extending in the direction and opening toward the inner diameter side is formed, and the corners on the inner diameter side in the rotation direction and the counter rotation direction of the upright portion are used as blades.
[0012]
[Action]
The food in the container also rotates in the same direction due to the rotation of the cutter. Due to this rotation, a centrifugal force is generated in the food, and the food flows radially outward. At this time, the food material collides with two corners on the inner diameter side provided in the upright portion of the cutter in the rotation direction and the counter rotation direction, where it is cut (cut) and crushed.
[0013]
The food material that has hit the cutter flows obliquely upward and outward while the movement in the rotation direction or the anti-rotation direction is restricted by the long groove of the upright portion. That is, the food material hitting the side surface of the cutter as in the conventional plate-shaped cutter is not jumped to the inner diameter side as it is, but is guided obliquely by the long groove. Therefore, a strong flow rising along the inner wall of the container is formed, and the food material efficiently and smoothly flows into the center of the cutter. As a result, the processing time of the food material can be reduced, and the particle size can be made uniform.
[0014]

A driven side 18 of the coupling gear is fixed to a lower end of the rotating shaft 16, and a substantially plate-shaped lower cutter 20 and a substantially plate-shaped upper cutter 22 are fixed to the upper end thereof. The upper cutter 22 serves as the cutter of the present invention, and its configuration will be described later. The container base 14 can be engaged from above with the coupling gear accommodating portion 12 of the mixer main body 10, and the driven side 18 of the coupling gear is engaged with the drive side of the mixer main body 10 during this engagement.
[0017]
Reference numeral 24 denotes a substantially inverted cup-shaped container for storing foods. The container 24 has a substantially conical shape with the upper end closed, and the outer periphery of the lower end can be screwed into the container base 14 from above. Therefore, when the container 24 is screwed to the container base 14, the upper end of the rotating shaft 16 stands upright at the center of the inner bottom of the container.
[0018]
Reference numeral 26 denotes a cap which can cover the container 24 from above. The cap 26 has a substantially inverted cup shape slightly larger than the container 24. The cap 26 is put on the container 24 in a state where the container 24 is screwed onto the container base 14 and the container base 14 is mounted on the coupling gear accommodating portion 12 of the mixer main body 10. When the cap 26 is strongly pressed, the motor is turned on.
[0019]
That is, the tongue portion 28 provided on the cap 26 can be engaged with the engagement concave portion 30 provided on the outer periphery of the upper portion of the mixer main body 10. A projection (not shown) provided on the edge (opening edge) enters the engagement hole 32 provided on the upper edge (opening edge) of the mixer body 10. As a result, the motor is turned on. If the pressing force of the cap 26 is reduced, the cap 26 is slightly lifted from the motor main body 10 by the return force of a spring (not shown), and at the same time, the motor is turned off.
[0020]
Next, the upper cutter 22 will be described. As shown in FIGS. 4 and 5, the upper cutter 22 is formed in a substantially plate shape in which both ends of a long thin metal plate are gradually narrowed and bent obliquely outward. It has a blade shape (or a rotating blade shape). At the center thereof, there is a horizontal portion 36 having a mounting hole 34 into which the rotating shaft 16 is to be engaged.
[0021]
The upright portion 40 gradually narrows in width toward the front end, and folds both sides of this straight line A inward along the straight line A in the longitudinal direction of the upper cutter 22 through the rotating shaft 16 (the mounting hole 34 through which the shaft 40 passes). The cross section is substantially V-shaped. That is, the cross section orthogonal to the longitudinal straight line A of the upper cutter 22 is substantially V-shaped. As a result, a long groove 42 that is long along the straight line A and that opens toward the front end 41 and the inner diameter side (the side of the rotating shaft 16) is formed in the upright portion 40.
[0022]
The upper cutter 22 can be formed by cutting and bending a thick plate made of stainless steel or the like. That is, the intermediate portion 38 and the upright portion 40 may be processed by pressing a material having a rectangular shape in cross section on a plane orthogonal to the straight line A in the longitudinal direction.
[0023]
FIG. 7 shows a cross section of the upper cutter 22, that is, a cross section orthogonal to the longitudinal direction of the long groove 42 of the upright portion 40. Here, a blade is formed at the inner diameter side corner portion 44 in the rotation direction (the direction of arrow F) of the upright portion 40 and the inner diameter side corner portion 46 in the anti-rotation direction. This blade may be formed by cutting and baking, but the sheared surface may be used as it is as a blade.
[0024]
The food material flowing in the outer diameter direction B by the centrifugal force hits the blades of these inner diameter side corners 44 and 46 and is cut. Or crushed. At this time, the food material is guided to the long groove 42 of the upright portion 40 and is sent obliquely outward. For this reason, the foodstuff moves while sliding on the inner diameter side corners 44 and 46, and the foodstuff is cut more smoothly.
[0025]
In the case where the upper cutter 22 of this embodiment is formed by shearing and pressing a thick plate having a rectangular cross section as described above, the inner diameter side corners 44 and 46 and the outer diameter side corners 48 and 50 are substantially perpendicular. (See FIG. 7). Therefore, the bisector of the two surfaces (one surface 42a of the V-shaped valley and the end surface 52 of the upright portion 40 in the width direction) sandwiching these corners 44, 46, 48, and 50 indicates that the food is centrifugal. , And almost coincides with the moving direction (B), so that the cutting and crushing of the food material are performed smoothly.
[0026]
Further, in this embodiment, the outer diameter side corner portion 48 in the rotation direction (F) advances in the rotation direction (F) beyond the inner diameter side corner portion 44. The outer diameter side corner 48 is also formed with a blade in the same manner as the inner diameter side corner 44, and the bisector of the two surfaces sandwiching the corner 48 hits the food material by the rotation of the upper cutter 22. If the direction is substantially coincident with the direction (C), the outer diameter side corner portion 48 can smoothly cut and crush the food material by the rotation of the cutter 22.
[0027]
As described above, according to this embodiment, the food material moved by centrifugal force is cut at the inner diameter side corners 44 and 46, and the food material is cut at the outer diameter side corner 48 by the rotation of the cutter 22. , The durability of the upper cutter 22 can be improved and the sharpness can be improved.
[0028]
As can be understood from the above description, if this upper cutter 22 is used, as shown by the arrow in FIG. 6, the food material is pushed up along the inner wall of the container 24 by the upright portion 40, and the upper cutter 22 It flows so that it falls near the center. The food material is cut and crushed at the two inner corners 44 and 46 of the upright portion 40 by centrifugal force. In addition, the rotation of the upper cutter 22 causes the outer diameter side corner portion 48 in the rotation direction to hit the food material, so that the food material can be further cut / crushed. Further, the rigidity of the upright portion 40 is increased by processing the long groove 42, and the strength of the cutter 22 is also improved.
[0029]
[Other embodiments]
8, 9, and 10 are a plan view, a side view, and a perspective view showing a cutter 22A according to another embodiment. This cutter 22A is the same as the upper cutter (cutter) 22 shown in FIGS.
[0030]
According to this embodiment, since the long groove 42A having a V-shaped cross section is longer in the longitudinal direction than that shown in FIGS. 4 and 5, the food material is efficiently captured by the long groove 42A and sent obliquely outward. be able to. In addition, since the portion serving as the blade, that is, the portion corresponding to the inner diameter side corners 44 and 46 and the outer diameter side corner 48 in FIG.
[0031]
[Other embodiments]
The cutter 22B shown in FIG. 11 is configured such that the cross-sectional shape of the upright portion 40B is substantially W-shaped and the long grooves 42B are arranged in two rows. According to this embodiment, it is possible to further form the intermediate corner portion 54 between the inner diameter side corner portions 44B and 46B in the rotation direction and the anti-rotation direction, and the crushing force or sharpness of the cutter can be reduced by using this as a blade. Further improve. That is, the food material flowing by centrifugal force is cut and crushed by the blades of the three corners 44B, 46B and 54.
[0032]
In the cutters 22, 22A shown in FIGS. 4, 5, 8 to 10, the cross section is substantially V-shaped, so the rigidity of the cutter increases and the strength increases. However, the cutter 22B shown in FIG. And becomes more suitable for cutting hard foodstuffs.
[0033]
[Other embodiments]
FIG. 12 shows an upright portion 40C of the cutter 22C having a substantially U-shaped cross section. According to this embodiment, a large amount of food can be held in the long groove 42C and can be smoothly fed obliquely outward. That is, by increasing the amount of food to be transferred, the flow in the vertical direction shown in FIG. 6 is enhanced. As a result, the food can be cut and crushed more smoothly.
[0034]
[Other embodiments]
The upright portion 40D shown in FIG. 13 has a substantially L-shaped cross section of the long groove 42D and is asymmetrical with respect to a straight line passing through the valley bottom of the long groove 42D. When using the cutter 22D having the upright portion 40D, if the long side 42d sandwiching the valley of the long groove 42D is positioned on the rotation direction (F) side, the food material guided obliquely outward by the long groove 42D when the cutter 22D rotates. Is easily held on the short side on the side opposite to the rotation direction, and the movement to the obliquely upper side is performed more smoothly.
[0035]
[Other embodiments]
In the cutter 22E shown in FIG. 14, the inner diameter side corners 44E and 46E of the upright part 40E are formed with acute angles. The outer diameter side corners 48E and 50E are deviated from the inner diameter side corners 44E and 46E in the anti-rotation direction and the rotation direction (F), respectively. According to this embodiment, the blades of the inner diameter side corners 44E and 46E are sharpened, and the ability to cut food, especially the ability to cut soft food such as vegetables, is improved.
[0036]
In the cutters 22, 22A, 22D, and 22E shown in FIGS. 7, 8, 13, and 14, straight lines (straight lines A in FIGS. 7, 8, 13, and 14) passing through the valleys of the long grooves 42, 42A, 42D, and 42E are formed. Although the cutter passes through the center of rotation of the cutter, the straight line may be deviated from the center of rotation. The straight line passing through the valley is desirably parallel to the straight line A passing through the center of rotation, but may be inclined with respect to the straight line A passing through the center of rotation.
[0037]
For example, if the straight line passing through this valley is inclined so that the outer diameter side is deviated in the anti-rotation direction compared to the inner diameter side of the cutter, the direction of the long groove in the direction of movement of the food material in the outer diameter direction accompanying the rotation of the cutter is changed. They can be aligned (or approached), and the flow of the food material in the long groove can be further smoothed. For this reason, the cutting and crushing of the food material at the inner diameter side corners become further smooth.
[0038]
In the above embodiment, the upright portions are provided on both sides in the longitudinal direction of the cutter. However, the present invention may be such that the upright portions according to the present invention are provided in only one of the longitudinal directions of the cutter. In this case, it is desirable to bend the other downward to balance the weight around the rotation axis.
[0039]
Further, it is preferable that the long groove provided in the upright portion is made gradually shallower toward the tip. This is because foodstuff cut and crushed at the inner diameter side corner by centrifugal force is captured in the long groove, moved to the tip, and then easily released from the long groove. In order to gradually reduce the length of the long groove toward the tip, a method of gradually reducing the width of the upright portion (width in a direction substantially orthogonal to the longitudinal direction) toward the tip and two sides sandwiching the valley of the long groove are used. And a method combining these two methods can be adopted.
[0040]
【The invention's effect】
According to the invention of claims 1 to 8, the upright portion provided on the outer portion in the longitudinal direction of the cutter is formed with a long groove which is long in the longitudinal direction and opens to the tip and the inner diameter side, and the inner diameter in the rotation direction and the anti-rotation direction. Since the side corners are blades, the foodstuffs follow the cutter and rotate, so that the centrifugal force acting on the foodstuffs causes the foodstuffs to strongly collide with the inner corners. At this time, the food material is guided by the long groove and moves obliquely upward and outward. For this reason, the food material moves while being in contact with the inner diameter side corner, so that the food material can be smoothly cut and crushed.
[0041]
Since the inner diameter side corner can be formed in at least the rotation direction and the counter rotation direction of the upright portion, the food material is cut and crushed at at least two places. Therefore, the processing speed is increased as compared with the conventional cutter, and processing can be performed in a short time. Further, since the food material flows strongly and smoothly in the vertical direction due to the long groove, cutting and crushing can be performed efficiently, and shaved ice and powder having a uniform particle size can be obtained. Further, the machining of the long groove increases the rigidity of the cutter, making the cutter suitable for processing hard foods.
[0042]
According to the ninth aspect of the invention, there is provided a cutter which is a component used in the mixer according to any one of the first to eighth aspects.
