Description

[Detailed Description of the Invention] This invention relates to a mixer that can improve the cutting and crushing ability of cooking ingredients put into a bottle.

As shown in FIG. 1, the conventional mixer includes a motor 2 installed inside a stand 1, a lower joint 4 screwed onto the upper end of a vertical rotating shaft 3 of the motor 2, and a lower joint 4 screwed onto the upper end of a vertical rotating shaft 3 of the motor 2. One cutter shaft 7 is rotatably supported by the bottle base 6 of the bottle 5 placed above, and a cutter 8 is pivotally attached to the upper end of the cutter shaft 7 inside the bottle 5. An upper joint 9 is screwed onto the lower end of the lower joint 7, and the engagement between the engagement piece on the upper surface of the lower joint 4 and the engagement piece on the lower surface of the upper joint 9 transfers the rotational force of the motor 2 to the rotating shaft 3 and the lower joint 4. , is transmitted to the cutter 8 via the upper joint 9 and the cutter shaft 7, so that the cutter 8 rotates at high speed. In addition, 10 is the start button,
Further, reference numeral 11 denotes a rib for guiding convection in the vertical direction, which is integrally provided on the inner wall of the bottle 5 so as to bulge inward.
2 is a spout formed in a part of the top opening of the bottle 5, and 13 is a lid body that closes the top opening of the bottle 5.

When the cooking material to be cut is put into the bottle 5 and the cutter 8 is rotated at high speed by pressing the start button 10, the cooking material is cut by the cutter 8, and the cooking material generated by the high speed rotation of the cutter 8 is cut. Convection, that is, a reverse fountain-like convection that is pushed upward from the bottom of the bottle 5 along the inner wall of the bottle 5 and descends from near the center above the cutter 8, as shown by the arrows in the figure, causes the cooking ingredients to be It is crushed and cooked in a prescribed manner. Here, the swirling flow generated by the rotation of the cutter 8 is corrected into vertical convection by the action of the ribs 11.

However, in the conventional mixer, when grinding cooking ingredients based on water, such as when making a fruit juice drink, convection occurs in the bottle 5, and the ingredients can be crushed well. When grinding only the ingredients without adding water, such as when using it as a preparation for cooking, convection does not occur in the bottle 5, and the ingredients do not hit the cutter 8 that rotates at high speed, resulting in so-called idling of the cutter 8. This has the disadvantage that the cooking material becomes coarsely ground or semi-ground.

For example, as described in Japanese Utility Model Application Publication No. 52-127078, there is a bottle with two cutters installed at the bottom of the bottle, but since both cutters rotate in the same direction, a simple large vortex flow occurs. The disadvantage is that vertical convection is not promoted.

This invention was made with the above points in mind, and includes a bottle placed on a stand with a motor installed therein, and a motor shaft of the motor that is rotatably supported on the bottom wall of the bottle. two connected vertical cutter shafts, a cutter pivoted on each of the cutter shafts in the bottle, a circular inner wall formed on the bottle on the circumferential side of both the cutters, The mixer is provided with an opening formed in an overlapping portion of the inner wall, and the two cutters are rotated in opposite directions.

Therefore, according to this invention, since the two cutters are rotated in opposite directions, the vortex becomes complicated and vertical convection is promoted, which has the effect of significantly improving the crushing ability.

Next, this invention will be described in the second section showing its practical example.
This will be explained in detail with reference to the drawings below.

First, FIG. 2 and FIG. 3 showing one embodiment will be explained.

In these drawings, 14 is a bottle placed on a stand 1' in which a motor 2' is installed, a bottle base 15 is provided at the bottom thereof, and the top surface is open. 16a, 16b
are two vertical cutter shafts rotatably supported on the left and right sides of the bottle base 15, and the right cutter shaft 16b is located above the rotating shaft 3' of the motor 2'. 17a, 17b are both cutter shafts 16a, 16
The upper end of b, that is, both cutter shafts 1 inside the bottle 14
6a and 16b, each with four blades, and both cutters 17
a and 17b are located close to each other. 18a,
Gears 18b are respectively attached to the lower ends of the cutter shafts 16a and 16b and engage with each other, and the lower surface of the right gear 18b is engaged with a lower joint 4' that is attached to the rotating shaft 3'. The engagement piece is integrally formed, and the gear 18b serves as an upper joint. Here, a straight pipe part 19 is formed in the lower part of the bottle 14 and is substantially perpendicular to the bottle base 15 from the lower end to a position 20 mm above the upper surfaces of the cutters 17a and 17b.
As shown in FIG. 3, the peripheral wall has a shape that surrounds the outside of both the cutters 17a, 17b in a circular shape and opens the overlapping part of the circles between the two cutters 17a, 17b, that is, it is almost like a gourd. Auxiliary ribs 20 protruding inward are formed at the intersection of the two outer circles of both the cutters 17a and 17b, that is, at the front and rear side walls of the central portion of the straight pipe portion 19, respectively.
This has the function of eliminating stagnation of the vortex flow caused by the rotation of both cutters 17a and 17b. Reference numeral 21 denotes a vertical convection rib formed on the inner surface of the bottle 14 so as to bulge inward.
The swirling flow caused by the rotation of b is corrected into vertical convection.

Therefore, when cooking ingredients are put into the bottle 14 and the motor 2' is driven to rotate the rotating shaft 3', the cutters 17a and 17b rotate at high speed in opposite directions, and the cooking ingredients are poured into the bottle 14. , a reverse fountain-like convection similar to the conventional one is generated, and two vortexes are generated due to the rotation of both cutters 17a and 17b, and each vortex has the effect of drawing up the material, and the rolled-up material is separated into two pieces. Katsuta 17
a and 17b, and the pulverization of the cooking material progresses rapidly. In addition, the straight pipe part 19 of the bottle 14 is formed into a substantially gourd shape, and both the cutters 17a, 1
Since the auxiliary ribs 20 are formed on the front and rear walls of the bottle 14 between the 7b, there is no stagnation on the outside between the two vortexes, and the entrainment of cooking ingredients into the vortex and convection is promoted, and the cutting and crushing ability is greatly improved. It will improve.

In addition, when grinding materials without using water,
By providing two cutters 17a and 17b and increasing the number of them than before, the cooking ingredients put into the bottle 14 not only have a higher probability of being hit by the cutters 17a and 17b, but also have a higher probability of being hit by the cooking ingredients due to the convection and vortex flow caused by both cutters 17a and 17b. The pulverization is improved by the entrainment action, and by forming the straight pipe section 19 at the bottom of the bottle 14, the convection and entrainment action become smoother, and the conventional drawbacks can be overcome.
Note that the bottle shape shown by the two-dot chain line in FIG. 2 is a conventional bottle shape.

Here, if the numbers of teeth of both the gears 18a and 18b of the above embodiment are different, the rotational speeds of the two cutters 17a and 17b will be different. In particular, in convection, the one with a higher rotational speed will have a higher convection height, and the one with a smaller rotational speed will have a higher convection height, and the one with a smaller rotational speed will have a higher convection height. An avalanche phenomenon occurs, which synergizes with the entrainment effect of the vortex to further improve the grinding performance and increase the stirring effect.

Furthermore, as shown in Fig. 4, the left cutter 1
If the size of the cutter 7a is made smaller than the right cutter 17b and the rotational speed of the larger cutter 17b is made higher than that of the small cutter 17a, the avalanche phenomenon described above will further increase;
When the rotation speed of the cutter a is made higher than that of the large cutter 17b, the peripheral speeds of both cutters 17a and 17b are averaged due to the difference in rotation speed and size, so the convection is averaged and the crushing performance is also improved. become good. Here, the small cutter 17a of the bottle 14
If you place the spout on the upper edge of the side, the cutter 1
Since the cross section of the bottle on the side 7a is smaller, it becomes easier to pour the crushed material into another container.

Next, FIGS. 5 and 6 show other embodiments.
The diagram will be explained.

These drawings show two cutters 17a and 17b.
Among the four blades of each of the cutters, two non-adjacent blades are saw blades 17a' and 17b', and according to this, the material rolled up by the high speed rotation of both cutters 17a and 17b can be removed. Saw blade 17
a' and 17b' can be used to efficiently grind the material, and it is particularly effective when grinding materials without using water.
