[Detailed Description of the Invention] (a) Industrial Application Field The present invention comprises a centrifugal separation cylinder which has a cutter for cutting material on the inner bottom and is rotated by a motor, and a centrifugal separation cylinder which is attached to the inner periphery of the separation cylinder and which cuts the material. 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 This type of pumper is known, for example, from Japanese Utility Model Publication No. 10504/1983. In order to make it easier to attach and detach the filter in this regulator, it is possible to provide a handle on the filter, but if the handle is made of synthetic resin, even if the handle has a symmetrical shape, there will be variations in the manufacturing process. If the left and right mounting is reversed, the weight balance of the filter with handle will be lost. For this reason, the weight balance must be adjusted for each item after the handle is attached, making the adjustment work difficult.

(c) Problems to be Solved by the Invention In view of the above drawbacks, the present invention aims to facilitate weight balance adjustment of a filter with a handle.

(d) Means for Solving the Problems The present invention has a main body housing a motor, a container supported on the main body, and a cutter for cutting material at the inner bottom, and the motor is operated in the container. a centrifugal separation cylinder rotationally driven by a centrifugal separation cylinder; a cylindrical filter detachably attached to the inner periphery of the centrifugal separation cylinder; and a handle rotatably supported on the upper end of the cylindrical filter; The diameter of one of the shafts is larger than that of the shaft hole in which the other shaft engages.

(e) Effect: By the above means, the left and right mounting positions of the handle to the filter are specified.

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 substantially cylindrical tube part 1b with a bottom that is attached to and detached from the base part 1a, and a base part 1
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 a reservoir. 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, into which a protrusion (not shown) of the base part 1a is fitted to connect the base part 1a and the cylindrical part 1b. Acts as a rotation stopper.

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. Each of the engaging grooves 31 has a vertical portion 31a whose upper end is open to the outside, through which engaging protrusions (second engaging portions) 32 described later of the filter 22 can be inserted vertically, and a separating tube formed at the bottom of the vertical portion 31a. Engagement protrusion 3 extending in the direction of rotation
2 consists of a horizontal portion 31b that is movable in the horizontal direction, and the upper wall 33 of the horizontal portion 31b has a horizontal surface 33a that is substantially horizontal on the vertical portion side and an inclined surface 33b that slopes downward on the opposite vertical portion side. is forming.

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 removable, and the abutting surfaces 41 and 42 are formed into inclined surfaces, and a hook-shaped convex 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 mentioned above, you can glue a ring-shaped body 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 ring-shaped flange 45 for retaining scraps is integrally provided on the inner periphery of the uppermost stage. Further, a pair of bearing portions 46 and 47 are formed on the top surface of the uppermost stage as shown in FIG.
6 and 47 are formed with shaft holes 46a and 47a, respectively.

Reference numeral 50 denotes a handle made of synthetic resin, and a pair of shafts 48 and 49 protruding inward from both ends of the handle 50 are engaged with the shaft holes 46a and 47a, respectively, so that the filter 22 can be raised and lowered. It is freely arranged.

The one shaft 49 has a larger diameter than the shaft hole 46a with which the other shaft 48 engages, so that the handle 5
0 is prevented from being installed in the opposite left and right direction. In addition, by cutting the tip of one shaft 49 obliquely 49a, the shaft 49 can be cut first as shown in FIG.
After fitting the shaft 49 into the shaft hole 46a, the shaft 49 is inserted into the shaft hole 47a.
Makes it easier to fit into the machine. Also, shafts 48, 49
Protrusions 48b, 49b are provided at the tips of the shaft holes 46a, 4.
Recesses 46b and 47b are respectively formed in the inner bottom wall of 7a, and by engaging the two, wobbling when the handle 50 is installed 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 cannot be dislodged or broken. 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 shaft 48 and
49, 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 side 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, projections 56a are formed from the upper surface of the lower stage, and grooves 57a in which the projections 56a fit are formed in the upper stage in a straight line in the vertical direction. A group of protrusions 56b and grooves 57b having the same shape as the group 57a are also formed at point-symmetrical positions with an interval of 180 degrees. These protrusions 56a, 56b... and grooves 57
a, 57b, . . . constitute a blocking means for blocking the filter 22 from sliding in the rotational direction between stages. The grooves 57a, 57b... are cut out in the radial direction, and the protrusions 56a, 56b... are removable in the radial direction.
There are large R parts 58, 58 at the left and right corners of a and 56b.
is formed into a substantially semicircular shape with a small flat portion 59 at the top. These protrusions 56a, 56
The corner portions of the grooves 57a and 57b are also formed in a substantially semicircular shape in accordance with the shape of b.

The engaging protrusions 32 are provided on the outer periphery of the uppermost stage to protrude horizontally outward at 90 degrees from each other, and cooperate with the engaging grooves 31 formed on the inner periphery of the upper end of the separation cylinder 1 to engage the filter 22. A filter holding means for pressing the filter 22 against the inner bottom surface of the separating cylinder 1 from above so as to prevent the vertical interval between the stages from expanding, and a means for preventing rotation of the filter 22 in the anti-separating cylinder rotating direction are constituted.

Regarding the filter holding means, the engaging protrusions 32 are formed such that their upper surfaces are lower than the height of the horizontal surface 33a of the groove 31 and higher than a part of the inclined surface 33b when the filter 22 is naturally contracted as shown in FIG. When the engaging protrusion 32 is inserted into the vertical part 31a of the groove 31 and then rotated, the protrusion 32 is inserted into the inclined surface 33.
b. 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 tube 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 part 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 tilted 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, as shown in FIG.
A protrusion formed on the bottom surface of the separation tube 1 to ensure smooth rotation of the filter 22 when the separation tube 1 is activated is a protrusion that is elongated in the circumferential direction or has a spherical lower end to ensure a gap between the inner bottom surface of the separation tube 1 and the bottom surface of the separation tube 1. It is desirable to reduce the sliding resistance of 68... is filter 22
The inner circumferential surface 30 of the separating cylinder 1 is formed on the outer periphery of each stage.
A liquid flow gap 69 is formed between the two.

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 the filter 22 is placed on a table as shown in FIG. 8, the stages of the filter 22 are brought into contact due to their own weight, that is, the protrusions 39 are brought into contact with the opposing surface, and no debris is attached. As shown in FIG. 4, when the filter 22 is pulled up by the handle 50, the gap 38 widens and the projections 56a, 56b, . . . and the grooves 57a, 57b, . . . are disengaged from each other. Also, the same filter 2
2 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, which also widens the gap 38 in the left-right direction, and the upper and lower ends It has a spring characteristic that when you hold it and shift it in the rotational direction, the diameter changes, and when these forces are released, it returns to its original state.

Further, the outer diameter of the filter 22 is formed to be slightly smaller than the inner diameter (tips of the protrusions 68) of the cylindrical portion 1b, and the inner circumferential surface 70 is tapered so that the diameter increases downward as shown in FIG. With this structure, the rotation of the separation tube 1 allows the scum to be accumulated from below, 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,
As shown in FIG. 1, 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. Reference numeral 73 denotes a push rod that is inserted into the material input cylinder 71 and pushes 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 ride on the upper end of the separation tube 1. Next, when the filter 22 is rotated appropriately, the protrusions 32... align with the vertical portions 31a of the grooves 31..., and the vertical portions 31a
Feeling depressed (see Figure 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 In this filter normal device state, 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 cylinder 1 rotates in the loading direction, but the filter 22 slides and rotates in the anti-X direction with respect to the separation cylinder 1 due to inertia. This rotation causes the protrusions 32 to move into the grooves 31.
The filter 22 is engaged with the inclined surface 33b of the filter 22, and the filter 22 is pressed downward, and an auto-clamping function is performed to resist the force of expanding the liquid flow interval 38 up and down and keep the interval 38 constant.

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 Removal of filter 2 After finishing the generation of the filter 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 dropped downward while remaining cylindrical. I can do it. Also, gap 3
Fibers etc. remaining on the gap 8 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 embodiment, and can also be applied to an embodiment in which the regulating piece 62 is not provided on the handle 50. It may also be formed in the shaft hole. Furthermore, it is also applicable to filters other than spiral filters.

(G) Effect According to the present invention configured as described above, since the handle is not installed in the left-right reverse direction, the balance of the filter is corrected in advance by taking into consideration the unbalance of the weight between the left and right sides of the handle. By keeping the weight of the filter in place, the weight of the filter can be balanced, making balance adjustment easier.
