Description

本発明は、主に一般の家庭で使用されるハンドミキサーにおける粉砕装置に関する。   The present invention relates to a pulverizing apparatus in a hand mixer mainly used in a general household.

従来のハンドミキサーにおける粉砕装置は軸部から半径方向に突出している粉砕羽根で構成されていた（例えば、特許文献１参照。）。
特表２００１−５００７７４号公報（図４） A pulverizing device in a conventional hand mixer is configured with pulverizing blades protruding in a radial direction from a shaft portion (see, for example, Patent Document 1).
Japanese translation of PCT publication No. 2001-500774 (FIG. 4)

従来のハンドミキサーにおける粉砕装置は前述したような構成である。したがって、粉砕羽根の回転により被粉砕物が液体と共に回転しながら粉砕されるのである。しかしながら、軸部の下方にある被粉砕物は粉砕羽根の回転域よりも内側であるから、粉砕羽根の回転作用が被粉砕物に伝わらずに滞留してしまい、その滞留した被粉砕物が粉砕羽根で粉砕されないまま残ってしまうことがあった。そこで、本発明は軸部の下方にある被粉砕物も確実に粉砕して粉砕されない氷や食品が残ることのないハンドミキサーの粉砕装置を提供することを目的とする。   The pulverizing apparatus in the conventional hand mixer has the configuration as described above. Accordingly, the object to be crushed is pulverized while rotating together with the liquid by the rotation of the pulverizing blade. However, since the object to be crushed below the shaft is inside the rotation area of the pulverization blade, the rotation action of the pulverization blade stays without being transmitted to the object to be pulverized, and the retained object to be crushed is pulverized. Sometimes it was left without being crushed by the blades. Accordingly, an object of the present invention is to provide a pulverizing apparatus for a hand mixer that reliably pulverizes an object to be crushed below a shaft portion so that no crushed ice or food remains.

本発明の請求項１は、粉砕装置の軸部の端部周辺位置から対称的に下方に延びる一対の粉砕突部を有し、且つ軸部から半径方向に延びる一対の粉砕羽根を有しており、一方の粉砕羽根は軸部付近の水平部とその先方で上方に傾斜する上方傾斜部とで構成され、他方の粉砕羽根は前記一方の粉砕羽根と反対の方向に延び且つ軸部付近の水平部とその先方で下方に傾斜する下方傾斜部とで構成されており、前記一方の粉砕羽根の上方傾斜部の傾斜角は前記他方の粉砕羽根の下方傾斜部の傾斜角よりも大きい構成である。 Claim 1 of the present invention, a pair of grinding blades from the end near the position of the shaft portion of the pulverizer symmetrically have a pair of grinding projections extending downward, and extends from the shaft portion in the radial direction One of the pulverization blades is composed of a horizontal portion near the shaft portion and an upper inclined portion that is inclined upward at the tip, and the other pulverization blade extends in a direction opposite to the one of the pulverization blades and near the shaft portion. It is composed of a horizontal portion and a lower inclined portion that is inclined downward at the tip, and the inclination angle of the upper inclined portion of the one grinding blade is larger than the inclination angle of the lower inclined portion of the other grinding blade. is there.

請求項２は、上方傾斜部の傾斜角はほぼ６０度であり、下方傾斜部の傾斜角はほぼ４０度であるよう要素が請求項１に付加された構成である。The second aspect is a configuration in which elements are added to the first aspect so that the inclination angle of the upper inclination portion is approximately 60 degrees and the inclination angle of the lower inclination section is approximately 40 degrees.

請求項３は、上方傾斜部の長さが下方傾斜部の長さよりも長い要素が請求項１又は請求項２のいずれか一項に付加された構成である。A third aspect of the present invention is a configuration in which an element in which the length of the upper inclined portion is longer than the length of the lower inclined portion is added to any one of the first and second aspects.

本発明は以上のような構成であって、請求項１は、粉砕装置の軸部の端部周辺位置から対称的に下方に延びる一対の粉砕突部を有し、且つ軸部から半径方向に延びる一対の粉砕羽根を有しており、一方の粉砕羽根の上方傾斜部の傾斜角は前記他方の粉砕羽根の下方傾斜部の傾斜角よりも大きい構成である。また、請求項２は、上方傾斜部の傾斜角はほぼ６０度であり、下方傾斜部の傾斜角はほぼ４０度である構成である。したがって、軸部の下方に滞留している氷や食品などを粉砕突部により粉砕することができる。また、粉砕突部の回転によって軸部よりも下方にある被粉砕物と液体を流動させるので、被粉砕物はその部分に滞留せず外側に流動する。したがって、その流動した被粉砕物を粉砕羽根によってさらに確実に粉砕することができる。また、請求項３は、上方傾斜部の長さが下方傾斜部の長さよりも長い構成である。したがって、上方傾斜部は高い位置まで延びており、上方の氷などを粉砕できる。 A present invention is the above configuration, according to claim 1, have a pair of grinding projections extending symmetrically downwards from the end near the position of the shaft portion of the crushing device, and radially from the shaft portion It has a pair of extending pulverization blades, and the inclination angle of the upper inclined portion of one of the pulverization blades is larger than the inclination angle of the lower inclination portion of the other pulverization blade. According to a second aspect of the present invention, the inclination angle of the upper inclined portion is approximately 60 degrees, and the inclination angle of the lower inclined portion is approximately 40 degrees. Therefore, ice, food, or the like staying below the shaft portion can be crushed by the crushing protrusion . Further, since the object to be pulverized and the liquid below the shaft part are caused to flow by the rotation of the pulverizing protrusion, the object to be pulverized does not stay in the part and flows outward. Therefore, the fluidized material to be pulverized can be more reliably pulverized by the pulverization blade. The length of the upper inclined portion is longer than the length of the lower inclined portion. Therefore, the upper inclined portion extends to a high position, and the upper ice and the like can be crushed.

次に本発明を実施するための最良の形態について説明する。この粉砕装置は主に氷を粉砕するためのものであり、粉砕容器に氷とジュースを入れて使用する。使用方法は、氷とジュースを入れた容器内の液状物に浸るように粉砕装置を入れ、粉砕装置を回転すればよいが、回転時にハンドミキサーや容器を振ることによってさらに効率的に粉砕することができる。図１に示すように粉砕装置は軸部１と、その端部に恒久的に固着された一対の粉砕羽根２，３と一対の粉砕突部４，５とから成る。粉砕羽根２，３と粉砕突部４，５は１枚の金属板を曲げ形成して一体に形成されている。図３に示すように一方の粉砕羽根２は、軸部１付近の水平部６とその先方で上方に傾斜する上方傾斜部７とで構成されており、その傾斜角はほぼ６０度である。この角度によって上方傾斜部７は高い位置まで延びており、上方の氷を粉砕できる。他方の粉砕羽根３は、軸部１付近の水平部８とその先方で下方に傾斜する下方傾斜部９とから構成されており、その傾斜角はほぼ４０度である。この角度により下方傾斜部９は低い位置まで延びていないが、あまり低くすると容器の底に当たってしまうので低くする必要はないのである。しかし、本発明がこの数値に限定されないことは勿論である。各粉砕羽根２，３の縁部は鋭利でない。   Next, the best mode for carrying out the present invention will be described. This crusher is mainly for crushing ice, and is used by putting ice and juice in a crushing container. The usage method is to put a crusher so that it is immersed in the liquid in the container containing ice and juice, and rotate the crusher, but more efficiently crush by shaking the hand mixer and container at the time of rotation. Can do. As shown in FIG. 1, the pulverization apparatus includes a shaft portion 1, a pair of pulverization blades 2, 3 permanently fixed to the end portion thereof, and a pair of pulverization protrusions 4, 5. The crushing blades 2 and 3 and the crushing protrusions 4 and 5 are integrally formed by bending a single metal plate. As shown in FIG. 3, one of the pulverizing blades 2 is composed of a horizontal portion 6 near the shaft portion 1 and an upper inclined portion 7 that is inclined upward at the tip thereof, and the inclination angle thereof is approximately 60 degrees. By this angle, the upper inclined portion 7 extends to a high position, and the upper ice can be crushed. The other crushing blade 3 is composed of a horizontal portion 8 in the vicinity of the shaft portion 1 and a lower inclined portion 9 that is inclined downward at the tip thereof, and the inclination angle thereof is approximately 40 degrees. The downward inclined portion 9 does not extend to a low position due to this angle, but if it is too low, it will hit the bottom of the container and need not be lowered. However, it goes without saying that the present invention is not limited to this value. The edge of each grinding blade 2, 3 is not sharp.

粉砕突部４，５は対称的に形成されており、図２に示すように軸部１の端部周辺の位置から下方に垂直に延びている。軸部１の端部周辺の位置とは、軸部１の外周から半径方向に粉砕突部４，５の厚みの中心までの距離が好ましくは軸部直径の５％〜１５％の距離の範囲であり、８％、９％あるいは１０％程度の距離がさらに好ましい。０％〜５％の範囲であってもよいが、例えば０％の場合は粉砕突部の内側寄りの一部が軸部１の外周よりも内部に入り込むことになる。粉砕突部４，５の全部が前述の範囲内になくてもよいことは勿論で、一部が前述したような数値内であればよい。粉砕突部４，５はやや内側に傾斜していてもよく、外側にわずかに傾斜していてもよい。図３に示すように粉砕突部４，５は三角形に形成されているが、この形状に限定されないことは勿論である。   The crushing protrusions 4 and 5 are formed symmetrically, and extend vertically downward from a position around the end of the shaft 1 as shown in FIG. The position around the end portion of the shaft portion 1 is a range in which the distance from the outer periphery of the shaft portion 1 to the center of the thickness of the grinding protrusions 4 and 5 in the radial direction is preferably 5% to 15% of the shaft portion diameter. A distance of about 8%, 9% or 10% is more preferable. Although it may be in the range of 0% to 5%, for example, in the case of 0%, a part closer to the inside of the crushing protrusion enters the inside than the outer periphery of the shaft portion 1. Of course, all of the crushing protrusions 4 and 5 do not have to be within the above-mentioned range. The crushing protrusions 4 and 5 may be slightly inclined inward, and may be slightly inclined outward. As shown in FIG. 3, the grinding protrusions 4 and 5 are formed in a triangular shape, but it is of course not limited to this shape.

粉砕羽根２，３と粉砕突部４，５は１枚の金属板を曲げ加工して形成される。まず、１枚の金属板を十字形に切断する。その際に粉砕突部４，５は三角形に切断される。粉砕羽根２，３の長さは粉砕突部４，５の突出長さよりも２倍以上長いが、この数値に限定されるものでない。この平板の状態で各粉砕突部４，５はそれぞれの２つの斜めの縁部１０，１０、１１、１１が形成され、それらの端部から粉砕羽根２，３との境付近まで斜めに研削され鋭利な縁部に仕上げられる。そのためにその鋭利な縁部１０は図１に示すように根元の屈曲部分まで形成されている。また、２つの斜めの縁部１０，１０は交点で端部１３を形成し、縁部１１，１１も交点で端部１４を形成する。図１及び図３に示すようにこれらの端部１３，１４は三角形の頂点のように尖っておらず、斜めに研削されて頂点の角が取れている。これは、粉砕時における端部１３，１４の耐久性を増すためである。   The crushing blades 2 and 3 and the crushing protrusions 4 and 5 are formed by bending a single metal plate. First, one metal plate is cut into a cross shape. At that time, the grinding protrusions 4 and 5 are cut into triangles. The length of the pulverization blades 2 and 3 is longer than the protrusion length of the pulverization protrusions 4 and 5, but is not limited to this value. In this flat plate state, each of the grinding protrusions 4 and 5 is formed with two oblique edges 10, 10, 11 and 11, and obliquely grinds from their ends to the vicinity of the boundary between the grinding blades 2 and 3. And finished with a sharp edge. Therefore, the sharp edge 10 is formed up to the bent portion at the base as shown in FIG. Further, the two oblique edges 10 and 10 form an end 13 at the intersection, and the edges 11 and 11 also form an end 14 at the intersection. As shown in FIGS. 1 and 3, these end portions 13 and 14 are not pointed like the apexes of a triangle, but are ground at an angle to form corners of the apexes. This is to increase the durability of the end portions 13 and 14 during pulverization.

一対の粉砕突部４，５が下方に垂直に折り曲げると同時に両粉砕羽根２，３も折り曲げられる。前述したように、一方の粉砕羽根２は、軸部１付近の水平部６を残してその先方で上方に傾斜するように折り曲げ、上方傾斜部７が形成される。また、他方の粉砕羽根３は、軸部１付近の水平部８を残してその先方で下方に傾斜するように折り曲げ、下方傾斜部９が形成される。下方傾斜部９の端部１２は傾斜羽根２，３の全体の最下位置であり、粉砕突部４，５の端部１３，１４よりも低い位置にある。   At the same time that the pair of crushing protrusions 4 and 5 are bent vertically downward, the crushing blades 2 and 3 are also bent. As described above, one of the pulverizing blades 2 is bent so as to incline upward at the tip, leaving the horizontal portion 6 in the vicinity of the shaft portion 1 to form the upper inclined portion 7. Further, the other pulverization blade 3 is bent so as to incline downward at the tip thereof, leaving the horizontal portion 8 in the vicinity of the shaft portion 1, thereby forming a downward inclined portion 9. The end 12 of the downward inclined portion 9 is the lowest position of the entire inclined blades 2, 3 and is lower than the ends 13, 14 of the grinding protrusions 4, 5.

このように形成された一体の粉砕羽根２，３と粉砕突部４，５はその交差部に設けられた孔に軸部１の端部が嵌合し恒久的に結合され粉砕装置は完成する。軸部１の上部に設けられたスリット１５，１６及びその周囲に巻かれたワイヤ１７は、図５に示したハンドミキサー１８の本体に内蔵されたモータに連なる回動軸に結合するための公知の装置である。   The integral crushing blades 2 and 3 and the crushing protrusions 4 and 5 formed in this way are fitted permanently into the holes provided at the intersections of the shafts 1 to complete the crushing apparatus. . The slits 15 and 16 provided in the upper part of the shaft part 1 and the wire 17 wound around the slits 15 and 16 are known for coupling to a rotating shaft connected to a motor built in the main body of the hand mixer 18 shown in FIG. It is a device.
