Description

DETAILED DESCRIPTION OF THE INVENTION (A) Industrial Field of Application The present invention comprises a centrifugal separation cylinder which has a cutter on the inner bottom for cutting material and is rotated by a motor, and a centrifugal separation cylinder which is attached to the inner circumference of the separation cylinder and which cuts the material. The present invention relates to a juicer that is equipped with a cylindrical filter that separates the processed material into waste and liquid, and stores the waste in a centrifugal separation cylinder.

(b) Prior Art This type of juicer is known, for example, from Japanese Utility Model Publication No. 10504/1983. The filter used in this juicer is formed into a comb-like shape to form a large number of vertical liquid outflow slits, and debris adheres and accumulates on the inner circumferential surface. In order to remove this adhered debris, the filter is elastically deformed, and the change in the spacing between the slits due to this deformation is relatively large at the lower end, but becomes smaller as it goes upward. Therefore, it was difficult to remove the scum, and the scum could not be removed by simply washing with water, and the scum had to be scraped off using a brush or the like, making the task of removing the scum difficult.

This difficulty in removing the scum has been the main reason why people are reluctant to use the juicer itself.

(c) Object of the Invention In view of the above-mentioned drawbacks, it is an object of the present invention to provide a juicer that is easy to use and has a good juice squeezing rate by making it easier to remove the scum.

(d) Structure of the Invention The structure of the present invention includes a centrifugal separation tube that has a cutter on the inner bottom for cutting the material and is rotationally driven by a motor, and a centrifugal separation tube that is detachably attached to the inner circumference of the separation tube to collect the cut material. The juicer is equipped with a cylindrical filter that separates waste and liquid and collects the waste in the centrifugal separation cylinder, and the cylindrical filter is provided with a tenth liquid passage gap having an expandable spiral shape. The lower end surface of this spiral filter is formed to be substantially flat, and a second
It is characterized by providing a liquid flow gap.

Due to this configuration, debris adheres to and accumulates on the inner periphery of the filter, but by expanding and contracting this filter in the direction of the cylinder axis or deforming it in a direction perpendicular to the cylinder axis, the interval of the first liquid flow gap changes greatly. Therefore, the scum can be easily removed from the filter, and if the filter is washed with the gaps widened, the scum caught in the gaps can be easily washed away. Further, since the second liquid flow gap is also formed between the lower end surface of the filter and the inner bottom surface of the separation cylinder, the amount of juice squeezed is increased.

The outer wall (65) has a tapered shape with a larger diameter at the bottom so that the lower part of the sealed space is wider than the upper part, allowing the liquid (68) to concentrate downward and preventing the liquid from rising upward. .

As shown in FIGS. 11 to 13, the spiral filter (30) is composed of a multi-stage cylindrical spiral body (30A) made of synthetic resin, for example, ABS resin, with a spiral liquid flow gap between each stage. (69) is formed and has spring properties. When this spiral body (3OA) is not applied with any force in the direction of contraction in the direction of the cylinder axis (natural extension state), the upper gap (69) is in a slightly enlarged state as shown in Fig. 11, and the lower gap (69) is in a slightly expanded state. It can be molded with a mold so that it will not expand due to its own weight, and when the lid (61) is closed, all the gaps (69) will be in the most contracted state, and from the state shown in the figure, no force will be applied in the direction of extension in the cylinder axis direction. When the force is applied, the gap (69) in Fig. 12 is expanded, and when this force is released, the first
It returns to the state shown in Figure 1 by its own spring force. When a force is applied in the horizontal direction, lateral displacement occurs between the stages, which also causes the gap (69) to expand in the left-right direction, and when the upper and lower ends are held and shifted in the rotational direction, the diameter changes. have. The length of this spiral body (30A) in the axial direction is the lid (61
) is formed to be approximately equal to the depth pl) of the cylindrical portion (29b) in the closed state, and even in the naturally extended state shown in FIG. 11! It is formed approximately equal to 1.

Further, the final stage (30a) (30
In a), the inner surface of the lid (61) and the cylindrical portion (29b) are configured so that the end surfaces (70) and (70) are flat surfaces with no steps.
) The outflow of waste is prevented by preventing large gaps from forming between the inner bottom surface and the inner bottom surface. The final stage (30a) (3
To change the height dimension of the cross section in 0a), you can glue ring-shaped bodies for height adjustment on the top and bottom surfaces of the spiral body with the same cross-sectional shape, or you can change the cross-sectional shape with a mold. Although this is possible, the latter is adopted in this embodiment. and the end (
71 Buff 1) is sufficiently thick in the axial direction to ensure strength at the end, and the end (71) (71) has a protrusion (72a) to prevent removal in the vertical direction and to prevent removal in the rotational direction. grooves (73a) (73b) into which the projections (72B>(72b) fit and engage, respectively) are formed on the mating surfaces corresponding to the ends (71) (71). Due to the first engagement between the protrusion (72a) and the groove (73a), force is applied to the final stage (30a) (30a) when pulling up the filter (30) with debris attached, and the filter (30) is pulled up.
be careful not to overextend the other protrusions (72b
) and the groove (73b), the filter (3
0) The diameter is expanded during rotation so that the first engagement does not come off. Since the above-mentioned first and second engagements are performed on the outer peripheral side of the filter (30), there is less adhesion of debris and cleaning is easy.

Further, the outer diameter of the spiral body (30A) is formed to be slightly smaller than the inner diameter of the cylindrical portion (29b) (the tips of the protrusions (57a), (57b), etc.), and the outer surface (74) is formed to be slightly smaller than the inner diameter of the cylindrical portion (29b). )
..., and the inner circumferential surface (75) is a tapered surface (75g>(75a) so that the diameter increases symmetrically from the midpoint (0) upward and downward, as shown in Fig. 4. By forming the separation cylinder (29), the rotation of the separation cylinder (29) causes the scum to accumulate from below first, and also facilitates the removal of the scum from the filter in the downward direction.In addition, in the embodiment, the filter (30)
In order to eliminate the vertical directionality, the diameter is larger toward the top and bottom, but if it has directionality, it may be formed into a tapered surface that becomes larger in diameter from the top to the bottom.

In addition, the cross-sectional shape of each step of the spiral body (30A) is as shown in FIG.
) The shape and sharpness reduce the flow resistance of the liquid flowing out from the gap (69), and the inner surface (76b) of each stage is made into a flat surface to facilitate the movement of waste. still,
The mode of this notch is not limited to that shown in the drawings.
6b) may be made into a curved surface ν).

Furthermore, the spiral body (30A>
The vertical width (F) is longer than E). By setting this FEB, when the internal space volume of the filter (30) is kept constant, the outer diameter of the filter (30) is prevented from increasing. However, if there is no restriction on the outer diameter, F≦E
You can also set it to . In order to prevent the filter (30) from losing its cylindrical shape even if the filter (30) is displaced laterally, the opposing surfaces of each stage are formed into flat surfaces (77a), (77b), etc.; , it may be formed to have a convex surface.

Also, referring to FIG. 4, when the spiral body (30A) forms a liquid flow gap (69) between each stage, a protrusion (87) to be described later on the bottom surface of the lid (61) and a low stage of the cylindrical part (29b) are formed. A liquid flow gap (79) (80) is formed between the upper surface of the part (52) and the gap between each stage is a constant value (
For example, in order to prevent the spiral gap (69) from becoming narrower than 0.4 mm, a flat surface (
Spacing projections (81)... are formed at equal intervals in the longitudinal direction of the gap (69) over substantially the entire width in the radial direction of the gap (77b), and in the gap <79) (80), the spiral body 30^ ) are formed with similar spacing-maintaining protrusions (82>) having the same height as the protrusions (81)... These protrusions (81)... (82)...
As a result, the ease with which liquid flows out is approximately equal throughout the entire vertical direction of the filter. Incidentally, the latter protrusion (82)... is provided on the lid (61> and the cylinder part (29) instead of being provided on the spiral body (30A>).
b) side, the former protrusion (81)... may be provided on the upper surface side of the spiral body (30A), or the protrusion (81)...
1)..., (82)... may be knurled protrusions.

In addition, the spiral body (30A) is set so that the winding direction is the direction in which the diameter widens, that is, for example, when the rotation direction of the separation cylinder (29) is counterclockwise (x) when viewed from above, the spiral body (30A) is set so that its diameter increases. The winding direction is clockwise when viewed from above.

Further, the lid (61) is fitted and locked into the large diameter portion (60) at the upper end of the cylindrical portion (29b), as shown in FIG. 4 and FIGS. 14 to 17, to prevent the filter (30) from being removed. and filter (30)
It is configured to have a function of preventing debris accumulated on the inner circumference from flying out. (61m> is a cylindrical vertical part that is in contact with the large diameter part (60), and as shown in Figure 15, six long vertically wide parts (85) are formed partially on the outer periphery of this part. The longitudinal groove (86) through which the protrusion (62) of the main part (60) passes

(61b) is a horizontal part having an opening (93) with a diameter smaller than the inner diameter of the spiral body (30A) and having a downward protrusion (92) on the periphery, and a downward annular protrusion (87) formed on the lower surface;
This presses the upper end surface of the filter (30) and prevents debris from flying out at the peripheral edge of the opening (93).

Additionally, a rotating handle (61c) (6
1c) is integrally protruded, and a protruding first matching mark (61d) is formed at a position corresponding to the handle, and a protruding first mark (61d) is also formed at a position corresponding to the inner part (86bl) of the groove (86b). A second matching mark (61e) is formed, and a display saying "One circle" is formed near this protrusion (61e), and a lid (61) is placed at a distant position.
A sign indicating the direction of ``Close 1 Remove'' is provided on each page. And, on the outer periphery of the upper end of the cylindrical portion (29b), there is a third projection mark (65b) indicating the position of the projection (62)...
is formed, and the first matching mark (61d) and the third matching mark (61d) are formed.
5b), insert the lid (61) into the cylindrical part (29).
Fit it into the large diameter part (60) of b), hold the handle (61c) and turn it in the "tighten" direction. Then, the protrusion (62
)... moves in the horizontal groove (86b)... and the protrusion (8
6c) and fits into the inner part (86bl) of the groove <86b), thereby reliably preventing the lid (61) from rotating. At this time, the second matching mark (61e) and the third matching mark (65b) match, and complete closing of the lid (61) can be easily confirmed by the feel or sound of the above-mentioned crossings -1, -'. Note that the first matching mark may be omitted by replacing it with the handle (61c) (61c).

Also, referring to FIG. 2, the container lid (21b) is cutter (

A handle (120) is provided on the hooker portion to facilitate removal from the front side of the main body.

Next, the operation of the above embodiment will be explained. First, as shown in Fig. 2, the juice liquid production preparation state is set, and the electric motor is driven to feed materials such as fruits and vegetables into the feeding tube (44) and press the push rod (9).
5) Push in. Then, the material is grated with the grater blade (39), but large materials such as leather that could not be grated and cut are cut into small pieces with the re-cutting blade (40)...
From the gap between the regulating plate (41> and the base part (29a)) or the notch in the hanging part <41a), it is blown off to the outside in the horizontal direction and attached to the inner periphery of the filter (30). This adhered cut material descends along the tapered surface (75a) of the filter (30) and is separated into scraps and liquid, and the liquid flows through the gaps (80) and (69). After reaching the inner periphery of the cylindrical part (29b) and moving upward through the flow gap (5B) formed by the protrusions (57a), (57b), and so on,

Even if the operator forgets to close the filter (61) during operation, the filter (30) can be prevented from popping out from the separation tube (29). Note that if the upper end of the filter (30) protrudes above the cylindrical part (29b) in the installed state, the upper end of the filter (30) will vibrate when operating without closing the lid (61), which may cause separation. There is a drawback that it pops out from the tube (29).

Then, a large diameter portion (60) is provided, and a partial protrusion (57c) is provided.

29b) It may be formed on the inner bottom surface and the lower surface of the lid (61).

Furthermore, the relationship between the winding direction of the filter (30) and the rotation direction of the separation tube (29) may be reversed, and as shown in FIG. (
121) and (122) may be formed integrally. This one member (121) prevents debris from flying out, and the other member (121)
127 elastically engages with the cylindrical portion (29b).

(f) Effects of the Invention According to the present invention configured as described above, the interval of the liquid flow gap can be greatly changed by expanding and contracting the spiral body in the direction of the cylinder axis or by shifting it in the direction perpendicular to the cylinder axis. This makes it easy to separate the debris from the filter, and also allows cleaning with a large liquid flow gap, making it easy to clean the filter and keeping the filter clean at all times. can be kept. Further, by forming a liquid flow gap between the lower end surface of the filter and the bottom surface of the separation cylinder, there are great effects such as an increase in the amount of juice squeezed.
