Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mixer that makes juice, etc. by putting fruits and milk in a cup and crushing and stirring them with a cutter rotating inside the cup.In particular, by improving the shape of the cutter, vegetables The present invention provides a mixer capable of chopping vegetables and meat into small pieces and with less splashing of liquid juice.

An embodiment of the present invention will be described below with reference to the accompanying drawings. In the figure, 1 is an electric motor, and screw 3 is attached to the main body 2.
It is attached by. Reference numeral 4 denotes a shaft of the electric motor 1, and a rotation transmission joint 5 is fixed to the upper part of the shaft, which is fitted into the rotation transmission joint 6 to transmit the rotation of the electric motor 1 to the cutters 7 and 8. Reference numeral 9 denotes a main shaft, a rotation transmission joint 6 is fixed to its lower part, and a cutter 7 and a cutter 8 are fixed to its upper part together with a sleeve 10. Reference numeral 11 is a tipped stand, and an insert fitting 12 is integrally formed in the center thereof.
A main bearing 13 is press-fitted into the insert fitting 12 and pivotally supports the main shaft 9. Reference numeral 14 is a tip with a cylindrical lower part and a shape that suddenly widens from a little above the cutter 7, and is screwed onto the tip base 11 via a gasket 15. 16 is a tip lid that covers the upper opening of the tip 14; 17 is a back plate that covers the lower opening of the main body 2;
18 is a leg, and 19 is a switch. Also, the shape of the cutting edge of the cutter 7 is such that the tip side is closer to the cutter 7 than the base.
It has a two-step bent shape that is delayed with respect to the rotational direction of the blade, and the cutting edge portion on the distal end side is a saw blade-shaped portion 7'. Further, in the embodiment, only the cutter 7, which is responsible for most of the cutting action, has this shape, but the same effect can be obtained if the cutter 8 has the same shape.

Next, the operation will be explained. First, when making juice, connect the spoon 11 to the main body 2 by bayonet, put fruits, etc. and milk in the spoon 14, close the spoon lid 16, and operate the switch 19 to open the electric motor 1.
When the cutter 7 and the cutter 8 are rotated, fruits, etc. are crushed and mixed with milk, etc. to produce juice.

It has been experimentally proven that the straight shape of the blade edge of a mixer produces the finest cuts, and the conventional cutter 7 has a shape as shown in FIG. 3. However, this shape has the disadvantage that the force for stirring the liquid is too strong, causing the liquid to jump up and easily leak from the top lid 16. On the other hand, in the case of the embodiment, the shape of the cutting edge of the cutter 7 is bent in two steps, with the tip side being delayed from the root side with respect to the cutter rotation direction, so the liquid is dragged and the force for stirring the liquid is weak. This eliminates the drawback of leakage as described above. In addition, the bottom of the tip 14 is cylindrical, and the shape is suddenly widened slightly above the cutter 7, so the cutter 7
The rapidly expanded portion has the effect of buffering the rotational state of the liquid stirred by the cutter 8, making it more difficult to leak.

In addition, with a blade bent in two stages, there is a problem that the material slips away along with the liquid and is difficult to cut finely.However, in this embodiment, the cutting edge on the tip side is made into a serrated part 7', so the saw blade It is possible to cut the material by hooking it on the shaped part, and experiments have shown that it can cut finer than a conventional straight-shaped cutter.

Next, if you want to chop vegetables or meat, put the ingredients in the pot 14 in the same way and operate it without adding any liquid, and the vegetables, meat, etc. will be chopped.

Here, the conventional shape of the cutter 7 does not produce the same phenomenon as a knife that cuts by pushing or pulling, so it has the disadvantage that it cannot cut meat well and tends to leave large pieces of meat behind. Furthermore, when chopping onions, etc., the cutting edge hits the material at a nearly right angle, resulting in poor sharpness and a problem in which a large amount of moisture comes out. In the example, the above-mentioned drawbacks have been solved, and since the shape is as shown in Figure 2, the same phenomenon as a knife that cuts by pulling occurs, and even meat that is difficult to cut can be finely cut. Also, onions, which are easy to cut and tend to release moisture, can be cut cleanly without having to forcefully cut them, and without releasing too much moisture.

In other words, the cutter 7 of the embodiment has cutting edges A° and B.
Since the blade has an angle of 20°, the cutting effect at the edge of the blade at B°, which has a small angle, increases the cutting effect when making jewelry, and reduces the cutting effect at the edge at A°, which has a large angle. This is prevented by creating a serrated part 7', and the large A° blade tip can handle the action of chopping hard-to-cut meat, etc., making it possible to perform two types of cooking, making juice and chopping, without any particular drawbacks. It is something.

As described above, the blade part of the present invention is straight and easy to process, which is advantageous in terms of cost.By improving the shape of the cutter and the shape of the blade, it is possible to chop vegetables, meat, etc. It is possible to provide a mixer with good cutting performance without liquid leakage, and its practical value is extremely large.
