Description

[Detailed Description of the Invention] The present invention relates to a juicer that has a material inlet with a large cross-sectional area so that coarse materials can be introduced into the juicer.

Generally, a juicer has a cylindrical material input port placed inside a centrifugal separation cylinder that has a bottomed truncated inverted conical tube with a peripheral wall as a filtration wall and a lowering plate placed on the inner bottom surface, and presses the material within the input port. The material is slid down by pressing the rod against the lowering metal, and the juice component is guided through the filter wall to the juice outlet.

In conventional juicers of this type, no cutting blade was provided at the center of rotation of the downer, and the material input port was placed away from the center of the downer.

This is because the circumferential speed at the center of rotation is zero, and it was thought that there was no cutting function.

Therefore, there was a problem in that the cross-sectional area of the input port could not be increased, and large materials could not be input unless they were cut into small pieces.

In addition, since the material must be fed into the material input port little by little, efficiency is poor.Furthermore, there is a problem in which the material that has been introduced rotates together with the lowering metal in the material feed port, preventing the material from being drawn down. It was wanted.

The present invention has been made to solve these problems, and provides a juicer that can input bulky ingredients as they are and can quickly obtain a large amount of juice by preventing the ingredients from rotating within the material input port. It is intended to.

Hereinafter, details of the present invention will be explained based on illustrated embodiments.

Figure 1 shows the juicer partially in cross section, with reference numeral 1 as a base, 2 as a main body case that is detachably attached to the base 1, and 3 as a case lid that closes the upper opening of the main case 2. It is.

The base 1 accommodates a motor therein, and a bottle stand 5 on which a juice container 4 is placed is provided on the left side of the motor accommodating portion in the drawing.

The motor rotation shaft 6 is arranged perpendicularly to the plane on which the base 1 is placed, and protrudes from the upper surface of the base 1.

A coupling 7 is fixed to the shaft end of the rotating shaft 6, and a bottom plate 9 of the centrifugal separation capacity 8 housed in the main body case 2 is detachably connected to the coupling 7.

The centrifugal separation capacity 8 has a truncated inverted conical cylinder shape with a bottom, and a large number of small holes are provided in the peripheral wall to serve as a filtration wall 10.

Further, on the inner bottom surface of the separating cage 8, a large number of cutting edges 11 as shown in FIGS.

In addition, at the center of the inner bottom surface of the separating tube 8, a center blade 13 which is taller than the cutting blade 11 and has a hollow pyramid shape is provided at the center of rotation.

A flange 14 is provided on the outer periphery of the upper opening of the separation tube 8 .

Inside the main body case 2, a juice receiver section 15 surrounding the centrifugal separation capacity 8 and a lees receiver section 16 located outside the juice receiver section 15 are provided. A juice outlet 17 that opens above the bottle stand 5 is formed at the bottom.

At the upper end of the juice receiver part 15, an annular partition plate 18 that closes the gap between the upper end of the juice receiver part and the flange 14 of the separating cylinder 8 is arranged very close to the flange 14. ing.

This partition plate 18 is pressed and held from above by the lower edge of the case lid 3.

The case lid 3 is integrally formed with a material input port 20 into which materials 19 such as fruits and vegetables are input.

As shown by the imaginary line in FIG. 2, this input port 20 has a rectangular inner cross-sectional shape, and the lower end has the lower outer periphery.
A flange 21 having an outer diameter approximately the same as the diameter of the sliding surface of No. 2 is projected.

The upper end of the inlet 20 protrudes above the case lid 3,
The lower end of this inlet is close to the lowering metal 12.

The central axis of the input port 20 is aligned with the central axis of rotation of the centrifugal separator 8.

In the figure, reference numeral 22 denotes a push rod that is inserted into the material input port 20 from the upper end side and presses the material 19 in the input port 20 against the lowering metal 12. is formed.

A recess 23 into which the center blade 13 is inserted is provided at the center of the tip of the push rod 22.

In the juice receiver, the opening of the bottle 4 is covered with a bottle lid 25 having a juice inlet 24.

Next, the operation of this juicer will be explained.

First, the juice receiver covers the bottle 4 with the lid 25 and places it on the bottle stand 5.

When the motor in the base 1 is rotated, the centrifugal separator 8 rotates together with the motor.

Therefore, when materials 19 such as fruits and vegetables cut into appropriate sizes are put into the material input port 20 and pressed against the lowering metal 12 with the push rod 22, the material is pressed down by the lowering metal 12 and becomes particles. The particles are moved outward by centrifugal force.

At this time, the lower end of the input port 20 approaches the sliding surface of the lowering metal 12, and a flange 21 having approximately the same diameter as the sliding surface protrudes from the outer periphery of the lower end of the inputting port 20, so that the lower end of the lowering metal 12 approaches the sliding surface. The particles that have been slid down pass through the small gap between the flange 21 and the cutting blade 11 and reach the filtering wall 1.
It is released to the bottom of 0.

Further, the juice component is dehydrated while moving upward while being pressed against the inner surface of the filtering wall 10 by centrifugal force, and the juice component is discharged to the juice receiver part 15 through the small hole of the filtering wall 10, and the juice outlet 17 and is poured into the bottle 4 via the inlet 24.

Further, the lees components sufficiently dehydrated in the centrifugal separation capacity 8 pass over the upper end of the separation tube 8 and are discharged into the lees receiver section 16.

In the figure, 26 indicates the juice poured into the bottle 4, and 27 indicates the lees components accumulated in the lees receiver 16.

According to this juicer, since the central axis of the material input port 20 is aligned with the rotation center axis of the centrifugal separation capacity 8, the input port 20
The cross-sectional area of 0 can be made large, and by doing so, it is possible to input a large amount of material without cutting it too finely.

Furthermore, although the center axis of rotation of the centrifugal separator 8 is located inside the material input port 20, the center blade 13, which is taller than the other cutting blades 11, is provided at the center of rotation of the lowering metal 12. Therefore, the material 19 is cut by the center blade 13 even at the center of rotation.

Moreover, since the push rod 22 is provided with a recess 23 at the tip thereof into which the center blade 13 is inserted, the push rod 22 can be pushed down sufficiently and the material 19 can be slid down to the end without wasting anything.

Furthermore, since the inner cross-sectional shape of the material input port 20 is square, the inner surface of the material input port 20 acts as a resistance wall, and the material 1
9 is prohibited from rotating in the slot 20, and the lowering metal 1
2, the sliding effect is further enhanced.

In addition, the present invention is based on the lower end surface of the material input port 20 and the lower end face of the lowering metal 12.
Although there is no particular limitation on making the sliding surface of the material 1 approximately the same outer diameter, with such a configuration,
9 can be brought into sufficient contact with the cutting blade 11 before moving from the lower end of the input port 20 to the filtering and retreating wall 10, and the sliding down effect is enhanced, which has the effect of increasing the drawing ratio. .

In addition, the present invention is not limited to the above-mentioned embodiments, and can be modified in various ways. For example, the inner cross-sectional shape of the inlet 20 may be triangular or a polygon with equal or larger dimensions.

Furthermore, in the embodiment described above, the center axis of the material input port 20 was made to coincide with the rotation center axis of the separation cylinder 8, but it does not necessarily have to be made to coincide with the rotation center axis of the separation cylinder 8. It's okay.

Furthermore, the shapes of the center blade 13 and the recess 23 can be modified as appropriate.

As described in detail above, the juicer according to the present invention has a material input port with a wide cross-sectional area that includes the center axis of rotation of the downer, so coarse materials can be input, and the cross section of the input port is formed in a polygonal shape. Therefore, even if the rotation center axis is included in the cross section, rotation of the material is prevented by the polygonal inner wall, and the material can be quickly slid down.

In addition, unlike conventional push rods, there is no need to prevent the material from rotating due to frictional resistance between the lower surface of the push rod and the material, and it is sufficient to simply press the material against the lowering metal. The effect is great, as it can significantly reduce the amount of water used.
