Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a mixer,
More specifically, it relates to a mixer capable of making fine shaved ice.

[0002]

2. Description of the Related Art A mixer is one in which a liquid such as water or milk is put in a bottle together with food materials, and a cutter is rotated to crush the food materials while convection. However, use other than the purpose of crushing the above-mentioned food material with a mixer has not been considered at all.

Applicants have attempted to make shaved ice using a mixer. The cutter of the mixer has an upwardly bent blade that rotates substantially above the shaft support of the cutter, and the rotation of this blade causes the foodstuffs and the like to stir and convect with the liquid. Since the efficiency of stirring and convection leads to a reduction in the time required for crushing, as shown in FIG. 16, the direction of the cutting edge is directed outward with respect to the rotational trajectory of the cutter.

When shaved ice is produced by using this cutter, when the ice convection of the cutter causes the ice to fall to the center of the cutter and is blown to the outside by centrifugal force, the blade edge of the cutter faces outward. Therefore, the ice collides against the side surface of the cutter, is repelled without being crushed, and it takes time to crush, and relatively large granular crushed ice pieces remain, so that uniform crushing is difficult.

Furthermore, four leg portions 68, 68, 68, 68 projecting outward from the cylinder body 61 are integrally provided from the inclined wall 64 of the cylinder body 61 to the lower vertical wall 65. These leg portions 68, 68, 68, 68 contact the lower portion of the inner surface of the peripheral wall of the bottle 1 when the tubular body 6 is inserted into the bottle 1 of the mixer 10, and the tubular body 61 is free from rattling. Support in.

As shown in FIG. 12, each rib 66 has a distance H from the rib 66 to the lower end of the lower vertical wall 65 of the cylinder body 61, and the upper edge of the upper blade 50 of the cutter 4 in the bottle 1 to the bottle 1. It is provided at a position where the shortest distance L to the rim is almost equal.

Further, as shown in FIGS. 12 and 13, each rib 66 hits the upper opening edge 1a of the bottle 1 while the cylinder body 61 is obliquely inserted into the bottle 1, and the rib 66 serves as a fulcrum. Rotates to correct the cylinder body 61 substantially coaxially with the bottle 1 and drop it to a fixed position. Here, since H ≈ L, the cylinder body 61 rotates about the point where the rib 66 hits the upper opening edge 1a of the bottle 1 as a fulcrum by the reaction of hitting the upper opening edge 1a of the bottle 1. It is possible to avoid the possibility that the lower portion of the cylinder main body 61 interferes with the upper blade 50 of the cutter 4 when it becomes substantially coaxial with the bottle 1.

Now, the mixer 10 configured as described above.
In the case of making juice using, the ingredients such as fruits and the liquid such as water and milk are stored in the bottle 1, and the cutter 4 is rotated by the drive unit 3. Then, the upper blade 50 suctions and roughly crushes the above-mentioned food material, the lower blade 50 finely crushes the food material that is crushed and dropped by the upper blade 50, and further returns the upper blade 50 to the above operation for an arbitrary time period. repeat.

When making shaved ice using this mixer 10, first, the cylinder 6 is inserted into the bottle 1 and set. When inserting the tubular body 6, the rib 66 of the tubular body 61 hits the upper opening edge 1a of the bottle 1 while the tubular body 61 is obliquely inserted into the bottle 1 and the tubular body 61 causes the rib 66 and the upper portion of the bottle 1 to come into contact. The cylinder body 61 is rotated about the point of contact with the opening edge 1a as a fulcrum so as to be substantially coaxial with the bottle 1 and dropped to a fixed position, so that the cylinder body 6 can be easily set. From the above relationship of “H≈L”, the cylinder body 61
Since the lower part of the cylinder does not interfere with the upper blade 50, the cylinder body 6 can be easily set, and the cylinder body is not scratched or scraped by the cutter 4.

Next, a large number of dice-shaped ice pieces made of, for example, an ice tray of a refrigerator are housed in this cylindrical body 6, and the cutter 4 is rotated by the drive unit 3. At this time, the upper blade 50 crushes the ice pieces, returns the crushed ice pieces to the upper side, and further repeats the operation of crushing the further crushed ice pieces, so that the inclined portion 55 and the vertical portion 56 of the upper blade 50 efficiently lower the crushed ice pieces. To crush. Furthermore, since the first side E and the second side F form the obtuse angle α in the vertical portion 56, the crushed ice pieces that are crushed and fall from the upper side to the blade edge (the front edge 52) because the blade edge faces the rotation center. Make sure they come into contact. That is, as in the conventional case, the direction of the cutting edge matches the rotation direction (the first side E and the second side F form a right angle), or the direction of the cutting edge faces outward from the rotation direction (the first side E and When the second side F forms an acute angle), the falling crushed ice pieces hit the surface of the vertical portion 56 on the rotation center side of the body portion 52 and are repelled toward the rotation center side and are not crushed.

In the set shaved ice removing cylinder 6, the tapered sloping wall 64 and the lower vertical wall 65 connected to the lower end of the sloping wall 64 narrow the outer peripheral space of the upper blade 50. It prevents falling from the lower opening edge of the main body 61 and smoothes the upward movement of the ice crushing pieces. In addition, the gently sloping portion 67a of each engaging portion 67 of the cylinder body 61 smoothes the rotational movement of the ice crushing piece inside the cylinder body 61.

The ice pieces in the cylinder 6 are efficiently crushed to form sherbet-shaped shaved ice in the cylinder 6. When the produced shaved ice is taken out from the tube body 6 and transferred to the tableware, the convex portion 63b of the tube body 61 hits the cut surface 62d of the tip portion 62b and is fixed in a state where the handle 62 is horizontally tilted. Even if the handle is tilted, the handle 62 does not prevent the removal of the shaved ice.

In this embodiment, the rib 66 is formed in a plurality of circular arc shapes, but by forming it into a single annular rib, any portion of the tubular body can be surely corrected to be coaxial even when it hits the bottle. You can improve the property.
