Description

[Detailed Description of the Invention] The present invention relates to a juicer that cuts and crushes vegetables, fruits, etc., and extracts juice by centrifugation.

Conventionally, there have been two types of juicers that extract juice by centrifugation: a so-called scum discharge type that has an inverted conical spinner, and a scum retention type that accumulates scum within a cylindrical spinner.

In both of these, as shown in FIG. 1, a rotating spinner 1' has a cutter 2' with a grater-like blade formed at the bottom, and an inlet 3' directly above the cutter 2' is located opposite to the cutter 2'. It is provided with a certain gap a.

However, because of this gap, the last part of the material input from the input port 3' is not cut by the cutter 2' and comes out as debris into the spinner 1'. In the type, this caused the spinning spinner to become unbalanced, causing large vibrations.

In addition, in both types, the presence of debris makes it impossible to squeeze out much of the juice from itself, causing a deterioration in the squeezing rate.Especially in the retention type, the debris blocks the passage of liquid, which greatly affects the squeezing rate. It had an impact.

Further, the production of debris has the disadvantage that the material is not used effectively.

The present invention eliminates these conventional drawbacks and provides a juicer that does not produce any residue.

One embodiment will be described below based on the drawings.

2 to 4, reference numeral 1 denotes a cylindrical spinner driven by a motor, and a cutter 3 having a grater-like blade 2 is fixed to the bottom of the spinner. A rotary blade 5 having several vertical blades 4 as shown in FIG. 1 is fixed between the cutter 3 and the spinner 1.

Further, directly above the cutter 3, a cylindrical input port 6 is provided with a size that covers the entire cutter 3 and a gap between the lower end surface and the cutter 3, into which material is input, and a through hole 7 through which the material passes. There is.

Further, on the lower surface of the input port 6, several convex portions 8 are formed concentrically close to the inside of the vertical blade 4 at small intervals.

Note that the convex portion 8 may be provided on the outside of the vertical blade 4 as shown in FIG.

Next, the operation will be explained.

In the case of the embodiments shown in FIGS. 2 and 3, the material input from the input lower is cut by the cutter 3, but the last part is thrown away as debris because there is a gap.

However, since there is a protrusion 8 on the bottom surface of the inlet, the spinner may not fly directly to the spinner 1, but may get caught on the protrusion 8 or spin round and round inside the protrusion 8, resulting in the impact and cutter. 3, it gradually becomes smaller and tries to slip out between the protrusions 8.

At this time, the remaining pieces are sandwiched between the vertical blade 4 rotating at high speed and the convex portion 8, and are cut into small pieces.

Incidentally, in the case of the embodiment shown in FIG. 5 as well, cutting is performed in substantially the same manner as described above.

In this way, according to the present invention, even if there is a gap between the input port and the cutter, the debris is finely shredded before reaching the spinner and dispersed within the spinner, so there is no imbalance caused by large debris. It also leads to improved drawing ratio and effective use of materials.
