Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a mixer, and in particular to an improvement in a cutting blade for crushing cooked food and turning it into fruit juice.

[Prior art] Conventionally, as a mixer of this kind, for example,
There were those shown in Publication No. 935 and Japanese Utility Model Publication No. 52-936. Figure 7 shows the structure of the cutting blade described in the above publication.
Reference numeral 1 indicates a pair of upper cutting blades that are inclined upward, and reference numeral 2 is a pair of lower cutting blades that are inclined downward. It is fixed by tightening it with etc.

In the conventional cutting blade configured as described above, the blade body is formed on the edge in the rotation direction, and both the upper and lower cutting blades 1,
The high-speed rotation (2) crushes the food to be cooked and obtains fruit juice.

[Problems to be solved by the invention] Conventional cutting blades are configured as described above, so when crushing food, for example, ice or chunks of food can be crushed between the upper cutting blade 1 and the lower cutting blade. It is easy to get caught in the narrow space a between 2 and 2. This is because the circumferential speed near the center of the cutting blade is slower than that at the tip, and the lumps caught in the space a rotate with the cutting blade, making it difficult to crush.
There was a problem with solid matter remaining in the fruit juice.

Moreover, if a solid object is caught between the cutting blades, an overload will occur in the rotational force, which may cause burnout of a drive device such as a motor. On the other hand, as cutting blades other than the above-mentioned cutting blades, there are an upper cutting blade 1 and a lower cutting blade 2 as shown in FIG.
Upper and lower cutting blades 1, with a spacer 5 interposed between them.
Some models have a wider space between them, but since the lower cutting blade 2 is in a horizontal position, the upper and lower cutting blades 1 and 2
The space between them was not wide enough, and the same problem as above occurred.

This idea was made in order to solve the problems mentioned above, and it is possible to obtain a mixer in which no solid matter remains unbroken between the upper and lower cutting blades, and no fixed matter is created in the fruit juice. purpose.

[Means for Solving the Problems] The mixer according to this invention forms a space between the upper and lower cutting blades via a spacing means, at least one of the upper cutting blades is tilted upward, and the lower cutting blade is tilted upward. At least one of the blades is inclined downward.

[Function] In this device, a space is formed between the upper and lower cutting blades, and the upper cutting blade is tilted upward and the lower cutting blade is tilted downward. Since a sufficient space can be obtained, it is possible to prevent the problem of solid matter being caught between the upper and lower cutting blades and remaining uncrushed when the food is crushed.

[Embodiment] An embodiment of this invention will be described below with reference to the drawings. Fig. 1 shows a cutaway front view of a mixer according to this invention, in which 6 is a cup made of a transparent container, with a handle 7 on the side. 8 is a lid that closes the upper opening of the cup 6, 9 is a base on which the cup 6 is placed, and a rotating device such as a motor (not shown) is disposed within the base 9. 10 is a rotating shaft that projects from the rotating device into the bottom of the cup 6, 11 is a pair of upper cutting blades that incline upward, and 12 is a pair of lower cutting blades that incline downward. The upper and lower cutting blades 11, 12 have a space between them with a spacer 13 as a spacing means interposed therebetween to maintain a space, and these are attached to the rotating shaft 10 with a nut 1.
It is fixed in place by tightening 4.

FIG. 2 shows a plan view of the upper cutting blade 11 and the lower cutting blade 12, and the upper and lower cutting blades 11 and 12 are arranged orthogonally in a cross shape. 15 is a wave-shaped blade formed on the edge of the upper cutting blade 11 in the rotational direction;
6 is a waveform blade formed on the edge of the lower cutting blade 12 in the rotational direction, and the waveform blade 15 of the upper cutting blade 11 has a waveform pitch and waveform depth larger than that of the waveform blade 16 of the lower cutting blade 12.

In the mixer of this invention configured as described above, when food is put into the pot 6, the rotating device is started, and the upper and lower cutting blades 11 and 12 are rotated at high speed (for example, 10,000 to 11,000 rpm), the food can be cooked. crushing begins. That is, the food to be cooked is first roughly crushed by the upper cutting blade 11 with a large waveform, and this crushed material is pushed downward by the upper cutting blade 11 and moved to the lower cutting blade 12 side with a finer waveform, where it is finely crushed. be done. Due to the above-mentioned crushing action, the food in the pot 6 is simultaneously rotated and stirred upwards and downwards, and the whole thing is evenly crushed into fruit juice.

In particular, this invention has an upper cutting blade 11 and a lower cutting blade 12.
A spacer 13 is interposed between the upper and lower cutting blades to maintain a predetermined space, and the upper cutting blade 11 is tilted upward and the lower cutting blade 12 is tilted downward to widen the space between the upper and lower cutting blades. Because of this, when crushing food, even if solid lumps are removed by the upper and lower cutting blades 1.
Even if the lumps enter between 1 and 12, the lumps will not be caught between the cutting blades and remain unbroken, and fruit juice without solids can be obtained.

In the above embodiment, both ends of the upper cutting blade 11 are inclined upward, and both ends of the lower cutting blade 12 are inclined downward, but as shown in FIG. 3, one side of the upper cutting blade 11 is inclined horizontally. The same effect as described above can be obtained even if the other one is tilted upward, or one of the lower cutting blades 12 is tilted downward and the other is made horizontal. Furthermore, as shown in FIG. 4, the tip of the cutting blade, which is directed upward or downward, may be made horizontal.

In addition, the distance maintaining means is not limited to spacers;
Any other means may be used as long as the distance between the lower cutting blades 11 and 12 is maintained.

Incidentally, the cutting performance of a mixer using a cutting blade according to this invention and a mixer using a conventional cutting blade are shown in FIGS. 5 and 6. Two cutting blades of type A in the figure were used according to this invention, and two of type B were used as conventional cutting blades. Further, in the figure, the vertical axis shows the remaining amount of fiber (g), and the horizontal axis shows the operating time of the mixer.

Figure 5 shows the case of apples, 200g of apples,
When mixing with an amount of water added of 200 c.c., after 30 seconds of operation time, the present mixer had 0.1g of fiber left in each fruit juice, yielding 97.2% of the fruit juice, whereas with the conventional mixer, only 0.1g of fiber remained. 3.3g (of which 1.2g of lumps remained without being crushed) and 3.9g (2.9g of lumps) remained. Furthermore, when the operating time is 1 minute, the inventive mixer yields 100% fruit juice, whereas the conventional mixer yields only 1.8g of fiber.
2.0g remained.

Figure 6 shows the case of carrots. When 200 g of carrots were mixed with 200 c.c. of water, the mixer of the present invention had a fiber content of 12.5 g with the operating time of 30 seconds.
Approximately 85.5g of fruit juice was obtained with 8.7g remaining, but with the conventional mixer, the fiber content was 73.3g (27.7g in chunks).
g (lump: 36.5 g) remained. In addition, after 1 minute of operation time, 0.1g of fiber remains in each of the mixers of the present invention.
Although 99.6% fruit juice was obtained, 12.1g and 10.8g of fiber remained with the conventional mixer.

[Effects of the invention] As described above, according to this invention, a space is formed between the upper and lower cutting blades via the spacing means, at least one of the upper cutting blades is inclined upward, and the lower cutting blade is tilted upward. By slanting at least one side downward, solids are not caught between the upper and lower cutting blades and remain uncrushed, and it is possible to obtain juice without solids mixed in the fruit juice. In addition, since no solid matter is caught between the cutting blades, there is no overload on the rotating shaft and burnout of the motor can be prevented.
