When cutting is performed at the same time, there is a problem that ice runs idle at the upper portion of the cutter and it takes time for cutting.

最も短時間に氷の切削ができるものである。Means for Solving the Problems In order to achieve the above object, a first means of the present invention comprises:
On the rotating shaft protruding from the inner bottom surface of the cup, a plate-shaped upper cutter and a lower cutter each having a blade portion formed in the rotating direction are provided, and the left and right intermediate portions of the upper cutter are bent upward, and the tip ends from both bent portions. This is a mixer in which the blade-forming side end surface of the plate-shaped cutter on the side is bent so as to be located on the rotation center side in the rotation trajectory from the inner corner of the opposite blade side end surface, especially bent at least 45 degrees with respect to the rotating horizontal plane In addition, ice can be cut in the shortest time experimentally by bending so that the rotation locus of the inner corner portion on the opposite side of the blade end side is 0.5 to 1.5 mm outer circumference with respect to the rotation locus of the blade portion forming side end surface portion. Things.

曲げたミキサーである。In addition, the third means, in addition to the first means, the end face of the upper blade on the side opposite to the cutting edge on the tip side from the left and right bent portions,
This is a mixer in which the middle of the cutter is bent slightly toward the center of rotation.
さらに、第４の手段は、第２の手段で行った反刃部側
端面部の外側角部の面取りを上カッター板材自身の塑性
変形より行わせたミキサーである。Further, a fourth means is a mixer in which the chamfering of the outer corner portion of the end face on the side opposite to the blade portion performed by the second means is performed by plastic deformation of the upper cutter plate material itself.

る場合でも、循環させることができる。Function The ice of 25 mm to 30 mm square made in a general household is drawn below the center of the cup by the rotation of the cutter, and is mostly cut by the upper cutter while circulating upward along the inner wall of the cup. Therefore, by the above-described first means, the blade edge portion, which is the blade portion forming side end surface portion, always hits the ice at the moment when the ice drawn downward from the center of the cup comes into contact with the upper cutter. In the conventional mixer, the ice hit the inner flat surface of the bent front end, and ice escaped to the central portion, so that the ice could not be cut in a short time. In addition, by bending the tip of the upper cutter 45 degrees or more with respect to the rotating horizontal plane, the overall length after bending is relatively short even if the effective length of the blade portion of the cutter is relatively long, and the rotation speed is reduced even with the same motor torque. Since the height of the upper cutter can be increased as well as being small, it can be circulated even when ice stops between a plurality of ribs provided in the cup.

たがって、第４の手段は、上カッターの反刃部側端面部
の外側角部の面取りを塑性変形により行い、上カッター
のカッター幅を狭くできるようにしたものである。By the way, according to the above configuration, when making a normal juice, the liquid is pressed against the inner wall of the cup with a stronger force than the conventional one at the tip from the bent portion, so that the liquid rises along the rib provided on the inner wall of the cup. Although the speed is increased and a problem such as pushing up the cup lid occurs, the problem can be solved by narrowing the width of separating the liquid by the rotation of the upper cutter by the second means and the third means. In this case, reducing the width of the upper cutter plate has the same effect as taking the second and third means, but when rotating at high speed and cutting ice or the like, a force that tends to spread in the centrifugal direction at the bent portion acts. In addition, it cannot be extremely narrowed because of repeated bending fatigue. Furthermore, the fourth means focuses on the bending fatigue, and the strength against bending fatigue is proportional to the section modulus of the plate material. In the case of the same material, cross-sectional shape, and cross-sectional area, when the surface hardness of the material increases due to plastic deformation, It is proportional to hardness. Therefore, in the fourth means, the outer corner of the end face on the side opposite to the blade portion of the upper cutter is chamfered by plastic deformation so that the cutter width of the upper cutter can be reduced.

め、長時間運転する必要がある。In FIG. 1, reference numeral 1 denotes a cup table having a plate-shaped bearing portion 3 which supports a cutter shaft 2 at a central portion, and is mounted on an upper surface of a mixer body (not shown). This cup stand 1
A cup 4 is removably attached to the upper part of the cup by a screw structure, and a cup lid 5 is provided at an upper opening of the cup 4. An upper cutter 6 and a lower cutter 7 fixed to the upper end of the cutter shaft 2 are arranged at the inner bottom of the cup 4, and are rotated by driving an electric motor built in the mixer body. As shown in FIGS. 2 (a) to 2 (c), the upper cutter 6 is bent upward at two places (A, A) in the middle on both the left and right sides, and at the tip outside the bent part (A). , FIG. 2 (c)
As shown in the figure, the blade-forming-side end surface portion (hereinafter, referred to as a blade edge portion) 8 of the plate-like cutter is formed with an inner corner 9a of the non-blade portion-side end surface portion 9a.
More in the center of the rotation locus ((a) dimension is 0.5 to
1.5mm). In other words, the rotating inner peripheral surface (c) of the plate-shaped cutter is retracted with respect to the rotation locus of the cutting edge portion 8 so that the cutting edge portion 8 hits the ice caught from above the center of the cup 4 so as to break the ice with a pickle or the like. Because it touches, it can be cut without escape of ice. When the inner peripheral surface (c) is tilted in the opposite direction to the above, the ice first comes into contact with the inner peripheral surface (c) near the cutting edge portion 8, and the ice escapes from the cutting edge portion 8 and cannot be cut. Therefore, it is necessary to drive for a long time because the ice can only be scraped little by little.

性が低下してしまう。By the way, according to the above-mentioned shape, when cutting the ordinary liquid juice, the inner peripheral surface (c) is inclined, so that the rotation of the upper cutter 6 spreads the liquid to the outer periphery, that is, the width of pushing the liquid ( b) is much larger than the thickness of the cutter (1 mm for ordinary household mixers), so that the outer surface (D) pushes the liquid against the inner wall of the cup 4 compared to the conventional mixer. 2 (c). In addition to the problem that it flows upward along a plurality of ribs 4a formed on the inner wall of the cup 4 and pushes up the cup lid 5, juice leaks from the upper opening of the cup 4. )
As the width (b) shown in (2) increases, the rotational resistance increases, and in the case of the same electric motor, the power increases and the rotational speed decreases, so that the machinability decreases.

よる折れを防止できる。For this reason, as shown in FIGS. 3 (a) to 3 (c), by chamfering the outer corner 9b of the end surface 9 on the opposite side of the blade, the width (c) for pushing the liquid is made larger than in FIG. Can also be narrowed. Also, as shown in FIGS. 4 (a) to 4 (c), the end surface 9 on the opposite side of the blade is also slightly bent toward the center of rotation at the bending line (e), thereby setting the width (d) for pushing the liquid to the fourth. It can be narrower than in the case of FIG. In addition, the third
By performing the chamfering in the figure by plate-like plastic deformation, the surface hardness can be increased and the bending due to the bending fatigue of the bent portion described above can be prevented.

を切削することができる。Effect of the Invention As described above, according to the configuration of the present invention, the blade forming side end surface of the plate-shaped cutter at the tip side of the left and right bent portions of the upper cutter is rotated by the rotation locus from the inner corner of the opposite blade side end surface. , The cutting edge portion comes into contact with solids such as ice before the inner peripheral surface, so that solids such as ice can be cut in a short time.

Improves surface hardness due to plastic deformation because the cutter shape required for cutting can eliminate juice leakage and reduced cutting performance of fruits etc., and the above chamfering is performed by plastic deformation of the cutter itself. Thereby, the fear of breakage due to bending fatigue at the cutter bending portion can be eliminated.
