This invention relates to a juicer that is equipped with a cylindrical filter that separates waste material from liquid into waste and liquid, and which collects waste in a centrifugal separation tube.

(b) Prior art As disclosed in Japanese Utility Model Publication No. 59-36170, there is a known pumper of this type in which a handle is provided at the upper end of the filter in order to facilitate attachment and detachment of the filter. ing.

However, in this configuration, since a pair of handles are formed, there is a problem that the assembly workability and the workability of raising and lowering the handle are poor.

In order to solve this problem, if the handle is made into a single unit, there is a risk that the balance of the filter will be lost when the handle is folded down, and abnormal vibrations will occur during driving.

(c) Problems to be Solved by the Invention The present invention has been made in view of the above-mentioned drawbacks, and it improves the workability of assembling the filter and the workability of raising and lowering the handle, and also solves the problem of unbalanced filters and the like. The purpose is to prevent abnormal vibrations during driving.

(d) Means for Solving the Problems The present invention provides a single synthetic resin handle that can be raised and folded at the upper end of the filter, and a handle that is approximately the same weight as the handle and is located at the upper end of the filter on the opposite side of the handle to the inverted position. A lever made by building up the balance correction part of almost the same shape as one piece.

(E) Effect With the above means, the handle can be installed only once, which improves the installation workability, and the raising and lowering of the handle is also simple since it only needs to be done once.

1 is inserted through the opening 19, and a liquid outlet 20 is formed at a position facing the low step portion 9 on the lower surface thereof. This outlet 20 is equipped with a valve body 21 that is opened and closed by a knob 21a.

Referring to FIGS. 1 and 3, the centrifugal separation tube 1 has a spiral filter 22 detachably attached to its inner periphery, is detachably connected to the low-speed connector 11, and is driven to rotate. Katsuta 23
a base part 1a fixed to the upper surface of the base part 1a; a bottomed substantially cylindrical part 1b that is attached to and detached from the base part 1a;
a and a ring body 1c for coupling with the cylindrical portion 1b.

Each part will be explained in detail below. Referring to FIGS. 2 and 3, the platform 1a is made of synthetic resin and consists of a horizontal portion 24 and a cylindrical support portion 25 projecting downward from the horizontal portion 24, and the lower inner periphery of the support portion 25. is removably engaged with the outer periphery of the low-speed connector 11.

The cutter 23 is attached to the horizontal portion 24 by caulking with screws or rivets, and forms grating blades 26 as cutting blades radially from the center.

The cylindrical portion 1b is made of synthetic resin and has a cylindrical shape with an open top and a bottom as shown in FIG. It serves as a low stage section 28 for storage. A cylindrical fitting part 29 is formed in the center of the high step part 27, into which the support part 25 of the platform part 1a is fitted. Referring to FIG. 4, 30... is an engagement groove formed on the upper inner circumference of the fitting part 29, and a protrusion (not shown) of the base part 1a...
... is inserted to prevent the rotation of the base portion 1a and the cylinder portion 1b.

The cylindrical portion 1b is held between the horizontal portion 24 by a ring body 1c that is fitted onto the outer periphery of the support portion 25 and bayonet-engaged therewith.

Referring to FIGS. 3 and 4, 30 is the filter 2.
The inner peripheral surface of the cylindrical portion 1b to which the cylindrical portion 2 is attached has a tapered shape with a larger diameter at the top so that the separated liquid can easily rise, and is also flat and has no rib-like protrusions. , the above-mentioned engagement groove (first engagement portion) 31 is formed at the upper end. The upper end of each engagement groove 31 is open to the outside and the filter 22
A vertical portion 31a through which engaging protrusions (second engaging portions) 32 described later can be inserted vertically, and this vertical portion 31a.
The upper wall 33 of the horizontal portion 31b is a horizontal surface 33a which extends in the counter-rotational direction of the separating tube in the counter-rotational direction and allows the engaging protrusion 32 to move horizontally. and an inclined surface 33b that slopes downward on the anti-vertical side.

Reference numeral 34 denotes a fluid balancer formed in a substantially L-shape across the side and bottom surfaces of the cylindrical portion 1b.The side surface of the cylindrical portion 1b is made into a double wall with a bottom opening, and this bottom opening is closed with a ring-shaped bottom cover 35. A sealed space is formed, and an appropriate number of longitudinal resistance plates 36 are integrally provided in this space projecting from the outer wall side, and an appropriate amount of balancer liquid 37 is sealed in this space.

Next, the structure of the spiral filter 22 will be explained. This filter is composed of a multi-stage cylindrical spiral body 22A made of synthetic resin, for example ABS resin, and a spiral liquid flow gap 38 is formed between each stage. On the surface constituting the liquid flow gap 38, there is a space-maintaining material on the lower surface of the spiral body 22A over almost the entire width in the radial direction so that the gap between each stage does not become narrower than a certain value (for example, 0.4 mm) when the filter 22 is pressed. Protrusions 39 are formed at equal intervals in the longitudinal direction of the gap.

As shown in FIG. 6, at the lowest stage of the filter 22, the terminal end 40 is detachable, and the abutting surfaces 41 and 42 are formed into inclined surfaces, and a hook-shaped protrusion is formed to maintain this engagement. 43 is formed. Reference numeral 44 denotes a concave portion formed so that the convex portion 43 engages in the vertical direction, and this concave-convex engagement prevents the terminal end from being disengaged downward.

Further, the lowermost stage of the spiral filter 22 is configured so that the lower end surface 45 becomes a flat surface with no step by changing the height dimension of the cross section. This prevents the outflow of waste by preventing the formation of gaps. To change the height of the bottom cross section above, you can either glue a ring-shaped body for height adjustment to the top or bottom of the spiral body with the same cross-sectional shape, or change the cross-sectional shape with a mold. However, in this embodiment, the latter is adopted.

Next, in the uppermost stage of the filter 22, the terminal end is not detachable as in the lowermost stage, but has an integral structure. Accordingly, the vertical interval of the upper terminal end 38a of the liquid flow gap 38 is formed wider than other parts, as shown in FIG. 8, to facilitate cleaning of this part. A continuous annular flange 45 for retaining scraps is integrally provided on the inner periphery of the uppermost stage. Also, on the top surface of the uppermost stage, there is a pair of bearing parts 46, 4 as shown in FIG.
7 is formed, and shafts (pivot parts) 48 and 49 are fitted into shaft holes (pivot parts) 46a and 47a of these bearing parts 46 and 47 and are rotatably supported, respectively, protruding inwardly at both ends. A semicircular synthetic resin handle 50 is rotatably provided.

The filter 22 is arranged such that one pivot portion of the filter 22 engages only one pivot portion of the handle 50.
2 and the shape of the pivot portion of the handle 50 are set, for example, as in the embodiment, the diameter of the hole 47a≧the diameter of the shaft 49>the diameter of the hole 46a≧the diameter of the shaft 48, so that the left and right sides of the handle 50 are reversed. By cutting the tip of one shaft 49 obliquely 49a, the work of first inserting the shaft 48 into the shaft hole 49a and then inserting the shaft 49 into the shaft hole 47a is made easier. make it easier. Further, projections 48b, 4 are provided at the tips of the shafts 48, 49.
9b into the recess 46 in the inner bottom wall of the shaft holes 46a, 47a.
b and 47b, respectively, and by engaging the two, wobbling when the handle 50 is attached is eliminated.

Further, ribs 51 and 52 are formed diagonally above the bearing parts 46 and 47 opposite to the shafts 48 and 49 to restrict the rotational direction of the handle 50 to one direction. Notches 50a, 50 for
It forms b. Therefore, if you try to tilt the handle 50 toward the side opposite to the handle inverted position, the handle 50 will collapse as shown in FIG.
The upper portions of the notches 50a, 50b abut against the ribs 51, 52, and rotation of the handle 50 is prevented. Without this blocking action, the weight balance of the filter 22 would be disrupted and abnormal vibrations would occur due to the handle 50 being tilted in the opposite direction, but the occurrence of such abnormal vibrations can be prevented by the above-mentioned blocking action.

In addition, in the above-mentioned blocking action, since the ribs 51 and 52 are formed to face the shafts 48 and 49, if a force is applied to force the handle 50 to fall in the opposite direction, it will not move as shown in Fig. 18C. As shown, the force F acts perpendicularly to the shafts 48, 49 and is applied to the entire shaft, so that the shafts 48, 49 will not come off or break. Therefore, the strength of the pivot portion of the handle can be improved. On the other hand, the ribs 51 and 52 are connected to the shafts 48 and 49 as shown by the dashed line in the figure.
If the shaft is placed in a position that does not face the shaft, the above force will act obliquely to the shaft, causing the shaft to come off or break from the base.

In order to maintain the left and right weight balance of the filter 22 when the handle 50 is in the inverted position, a balance correction part 53 having substantially the same shape as the handle 50 is integrally built up on the uppermost stage opposite to the inverted position. By forming this build-up in a substantially semicircular shape at the upper end of the filter 22, compared to a structure in which the balance is corrected by partially protruding, the filter becomes extremely high, and the partially protruding part This prevents unnecessary wind from being generated.

Reference numeral 54 denotes a vertical wall formed inside the handle 50 at the upper end of the filter 22 to be higher than the bottom surface of the handle 50 in the reclined position. Without this vertical wall 54, when a lot of waste is generated and it starts to fly out beyond the flange 45, it will fly out horizontally and bite into the bottom of the handle 50, lifting the handle 50, and the weight balance of the filter 22 will be affected. Although breakage vibrations may occur or the handle 50 may come into contact with the container lid 18b, resulting in damage, such inconveniences can be avoided by forming the vertical wall 54.

Between each stage of the filter 22, a projection 56a is provided from the upper surface of the lower stage, and the projection 56a is located on the upper stage.
Concave grooves 57a... into which the protrusions 56a... and concave grooves 57a fit are formed in a straight line in the vertical direction.
...Protrusions 56b and grooves 57b having the same shape as the groups are also formed at points symmetrical to each other with an interval of 180° between the groups. These protrusions 56a, 56b...
. . . and the grooves 57a, 57b . The grooves 57a, 57b... are cut out in the radial direction, and the protrusions 56a,
56b... is a substantially semicircular shape that can be freely engaged and detached in the radial direction, and has large rounded portions 58, 58 formed at the left and right corners of each protrusion 56a, 56b, and has a small flat portion 59 at the top. It is becoming a state. A concave groove 57 is formed according to the shape of the protrusions 56a and 56b.
The corners of a and 57b are also formed in a substantially semicircular shape.

The engaging protrusions 32... are arranged at 90 degrees each other on the outer periphery of the uppermost stage.
The separation cylinder 1 is provided horizontally outwardly at an interval of
a filter pressing means that presses the filter 22 from above against the inner bottom surface of the separating cylinder 1 so as to prevent the vertical interval between the stages of the filter 22 from expanding in cooperation with the engagement groove 31 formed on the inner periphery of the upper end; It constitutes a means for preventing rotation of the filter 22 in the anti-separation cylinder rotation direction.

Regarding the filter holding means, the engaging protrusion 32 has a top surface height that is similar to that of the filter 22 shown in FIG.
is formed lower than the height of the horizontal surface 33a of the groove 31 and higher than a part of the inclined surface 33b in the naturally contracted state of the groove 31.
When rotated after inserting the protrusion 32 into the inclined surface 3
3b. This slope engagement constitutes a filter holding means that presses down the filter 22 from above so as to prevent the gap between the stages from expanding, and when the separation tube 1 is started, the filter 22 moves in the opposite direction of rotation of the separation tube due to inertia. It constitutes a rotation preventing means for preventing rotation.

Reference numeral 62 denotes a fan-shaped regulating piece integrally formed at one end of the handle 50, which has a radius around the first vertical surface 63 and the handle rotation center O when the handle 50 is rotated to the inverted position (see Fig. 12). A circular arc surface 64 formed by drawing an arc upward from the bottom of the first vertical surface 63 at R, and a second vertical surface 6 with a small tolerance formed at the upper end of the circular arc surface 64.
5. This first vertical surface 63 functions as a support surface that comes into contact with the upper end surface 61 of the separating tube 1 and supports the handle 50 in a vertically standing state (see FIG. 15) when the regulating piece 62 is not fitted into the groove 31. death,
The second vertical surface 65 is formed by the regulating piece 62 when the handle 50 is in the inverted position.
The filter contacts the wall 74 of the vertical portion 31a in a state where it is fitted into the engagement groove 31 (see FIG. 17), and the projection 32 and the horizontal portion 31b are disengaged from each other, that is, in the direction of rotation of the separation cylinder X. Functions as a rotation stopper. Furthermore, the formation of the arcuate surface 64 makes it easy to raise and lower the handle 50.

Since the groove in which the regulation piece 62 engages uses the vertical portion 31a of the groove 31 in which the engagement protrusion 32 engages, the handle 50 is installed near the protrusion 32 in order to make this possible. Opening width l1 of portion 31a
is formed to be shorter than the distance 12 between one end 32a of the engaging protrusion 32 and the second vertical surface 65 when the handle is in the inverted position shown in FIG. Even if the groove 31 is applied, the protrusion 32 engages with the horizontal portion 31b of the groove 31 and is prevented from coming off in the upward direction.

66... are protrusions formed on the bottom surface of the separation cylinder 1 and the bottom surface of the lowest stage of the filter 22 so as to secure a liquid flow gap 67 between the inner bottom surface and the bottom surface of the filter 22, as shown in FIG.
In order to allow the filter 22 to rotate smoothly when the separation tube 1 is started, it is desirable to have an elongated shape in the circumferential direction or to have a spherical lower end to reduce the sliding resistance between the filter 22 and the inner bottom surface of the separation tube 1. 68 are projections formed on the outer periphery of each stage of the filter 22 and form a liquid flow gap 69 between the filter 22 and the inner peripheral surface 30 of the separation cylinder 1.

The filter 22, except for the handle 50, is integrally molded with resin using a mold. During molding, the filter 22 is molded with a relatively large liquid flow gap 38, and after being removed from the mold, it is thermally modified to reduce the gap. 38 is made narrower, and when placed on a table as shown in Fig. 8, the stages of the filter 22 come into contact due to their own weight, that is, the protrusions 39... contact the opposing surface, and there is no residue attached. In this state, when the filter 22 is pulled up by the handle 50 as shown in FIG. 4, the gap 38 widens and the protrusions 56a, 56b... and the grooves 57a, 57b...
It is configured so that the engagement with the Further, the filter 22 expands when a stretching force is applied in the vertical direction, and when a force is applied in the horizontal direction, lateral displacement occurs between the stages, thereby expanding the gap 38 in the left-right direction. It also has a spring characteristic in which the diameter changes when the upper and lower ends are held and shifted in the rotational direction, and it returns to its original state when these forces are released.

Further, the outer diameter of the filter 22 is formed to be slightly smaller than the inner diameter of the cylindrical portion 1b (the tips of the protrusions 68), and the inner circumferential surface 70 is tapered so that the diameter increases downward as shown in FIG. By forming the separator cylinder 1, the rotation of the separation tube 1 causes the scum to be accumulated from below first, and also facilitates the removal of the scum from the filter in the downward direction.

In addition, the cross-sectional shape of each stage of the filter 22 is such that the upper and lower corners of the outer surface are notched as shown in FIG. The flat surface facilitates the movement of debris. Note that the form of this notch is not limited to that shown in the drawings.

Next, referring to FIG. 1, the container lid 18b has a material input tube 71 integrally provided vertically so as to face a portion off the center of the cutter 28. and,
The container lid 18b is fixed in a closed state and pressed onto the main body case 2 by clamp devices 72, 72 which are rotatably attached to the main body case 2 as shown in FIG. Reference numeral 73 denotes a push rod that is inserted into the material input tube 71 to insert the material.

<Operation Description> 1. Normal installation of filter 22 When the handle 50 of the filter 22 is held by hand, the filter 22 will be in an extended state as shown in FIG. 4, and the filter 22 will be inserted into the separation tube 1 from the lower end. As it is inserted, the protrusions 32 generally rest on the upper end of the separation tube 1. Next, when the filter 22 is rotated appropriately, the protrusion 32...
... coincides with the vertical portion 31a of the groove 31... and falls into the vertical portion 31a (see FIG. 15).

When the filter 22 is rotated a little further from the state shown in FIG. 15, the regulating piece 62 falls into the groove 31 a little (see FIG. 16).

In this state, the engagement protrusion 32 is already prevented from coming off upward by the horizontal portion 31b of the groove 31. Then, when the handle 50 is folded down, the normal mounting state shown in FIG. 17 is realized, and the second vertical surface 6 of the regulating piece 62
5 and the wall 74 of the vertical portion 31a face each other, and when they come into contact with each other, the rotation of the filter 22 in the separation tube rotation direction X can be prevented.

2. Rotation of Separation Cylinder 1 and Generation of Youth With the filter normally installed, the container lid 18b is set as shown in FIG. 1, and the clamp devices 72 are rotated to set it as shown by solid lines. When the operation switch 17 is turned on, the separation tube 1 rotates in the X direction, but the filter 22 slides and rotates in the counter-X direction with respect to the separation tube 1 due to inertia. This rotation causes the protrusion 32... to move into the groove 3.
1... engages with the inclined surface 33b of the filter 22.
is pressed downward, and an auto-clamping function is performed to keep the gap 38 interval constant against the force that tries to expand the liquid flow gap 38 up and down.

Then, materials such as fruits and vegetables are introduced into the input tube 71 and pushed in using the push rod 73. The material is then grated by the grater blade 28, thrown outward in the horizontal direction, and attached to the inner periphery of the filter 22. This adhered material to be cut descends along the tapered inner circumferential surface of the filter 22 and is separated into scraps and liquid, and the liquid flows through the gaps 38 and 67 and reaches the inner circumference of the cylindrical portion 1b. reaching the flow gap 69
After moving upward through the separation cylinder 1, the liquid flows out of the separation cylinder 1 and is received in the container 18. This liquid flows down from the outlet 20 and is received by the cup 5.

On the other hand, the waste is accumulated sequentially from the inner lower end of the filter 22. When the material is further cut, the cut material also accumulates in the upper half of the filter 22 and is blocked by the flange 45.

3 Removing the filter 22 After finishing the youth generation and turning off the switch 17,
Contrary to when starting, the filter 22 rotates relatively in the separation tube rotation direction X due to inertia and automatically returns to the state shown in FIG. 17. In this state, after removing the container lid 18b, the handle 50 is raised up, pulled up slightly, and then rotated in the direction of rotation of the separation tube as shown in FIG. 15 to disengage the protrusion 32 from the horizontal portion 31b. In this state, the filter 22 can be taken out from the separation cylinder 1 by pulling up the handle 50.

4 Removal of debris This drawn out state is similar to that shown in Figure 4, but depending on the adhesive strength of the debris adhering to the inner periphery, the gaps between the stages of the filter 22 may remain in close contact or in close proximity. By shifting the filter 22 horizontally in the direction that connects the corresponding pair of protrusions 56a..., 56b..., stretching it up and down, and further shifting it in the rotational direction, the waste can be moved downward while maintaining its cylindrical shape. It can be dropped. In addition, the maintenance particles remaining in the gap 38 can be easily washed away by washing with water while the gap 38 is widened.

It should be noted that the present invention is not limited to the above-mentioned embodiments, but can also be applied to a regulator having a filter shape other than a helical filter.

(g) Effects According to the present invention configured as described above, the workability of attaching the handle is good. In addition, since the upper end of the filter is overlaid with approximately the same shape and weight as the handle, it is easy to correct the balance, and the filter does not protrude partially to correct the balance, which eliminates the inconvenience caused by this partial protrusion. The effect is great.
