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, but 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 is difficult to remove the scum, and the scum cannot be removed by simply washing with water, and the scum must be scraped off using a brush or the like, making it difficult to remove the scum.

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

(c) Purpose 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 to simplify the structure of the filter holding means by making it easier to remove the scum.

(D) Structure of the Invention The structure of the present invention consists of a centrifugal separation cylinder that has a force and tension for cutting the material at the inner bottom and is rotated by a motor, and a centrifugal separation cylinder that is detachably attached to the inner circumference of the separation cylinder and that is used for cutting the material. The juicer is equipped with a cylindrical filter that separates the waste material into waste and liquid, and the cylindrical filter is configured with a spiral body having an expandable spiral liquid flow gap, and the centrifugal separation A filter holding means is provided above the cylindrical filter of the cylinder, and the winding direction of the screw and bank body is set in the direction in which the diameter thereof expands as the centrifugal separation cylinder rotates.

Due to this configuration, debris adheres and accumulates on the inner circumference 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 liquid flow gap changes greatly. If the filter is cleaned while the scum is easily removed from the filter and the gap is widened, the scum caught in the gaps can be easily removed. In addition, since a force is applied to the helical body so as to expand its diameter and reduce the length in the axial direction of the cylinder due to the rotation of the separation cylinder, a large force is not applied to the filter holding means when producing juice liquid, thereby preventing the filter holding means from being destroyed. Nor.

Each part will be explained in detail below. The table part (29a) is made of synthetic resin and consists of a horizontal part (31) and a cylindrical support part (32) that projects downward from the horizontal part (31).
The protrusion (33) formed on the inner periphery of the lower part of the connector (32) is removably engaged with the groove (18) on the outer periphery of the low-speed connector (11), and the lower end (34) is connected to the connector (11). ) and is removably connected to the low-speed funector (11).Furthermore, on the outer periphery of the lower part of the support part (32) there are temporary fixing protrusions (35) and engagement protrusions (36). )... are each formed, and the top outer circumference has a protrusion for preventing rotation (
37)... is formed.

The cutter (38) is attached to the horizontal part (31) by caulking with screws or rivets, and forms grating blades (39) as cutting blades radially from the center, and also scrapes the remaining material by cutting the periphery. A plurality of recutting blades (40) for finely recutting are formed and machined.

The cylindrical portion (29b) is made of synthetic resin and has a bottomed cylindrical shape with an open top as shown in FIG. None, the outer periphery is used as a low step part (52) for collecting waste. The high step part (46) has an outer periphery (46a) formed in a tapered shape that expands downward to facilitate the separation of debris accumulated on the low step part (52), and a platform (46a) in the center. Support part (32) of 29a)

Note that the support portion (32) and the ring body (29c) may be fitted together by a screw PR (not shown) instead of bayonet engagement.

(56> is the cylindrical part (29b) to which the filter (30) is attached.
) has a tapered shape with a thicker diameter at the top so that the separated liquid can easily rise, and a plurality of vertical protrusions (57) are formed at appropriate intervals. However, a liquid flow gap (58) is provided between the filter (30) and the outer circumferential surface of the filter (30).

(59) is a filter locking protrusion formed on a part of the lower end corner of the inner peripheral surface 56), which prevents the filter (30> from rotating), and is formed on an extension of the protrusion. However, it is not limited to this.

Note that the liquid flow gap (58) may be provided by forming protrusions (not shown) on the outer circumference of the filter (30) instead of forming protrusions on the inner circumferential surface (56). .

(60) is a large-diameter portion formed at the upper end of the inner circumferential surface (56), and a locking protrusion (62) of the lid (61) described later is integrally provided to protrude inward.

(63) is a fluid balancer formed in an abbreviated shape over the side and bottom surfaces of the cylindrical portion (29b). The opening is closed with a ring-shaped bottom cover (66) to form a sealed space, and an appropriate number of vertical resistance plates (67) are integrally provided in this space projecting from the outer wall (65) side. At the same time, an appropriate amount of balancer liquid (68) is sealed in this space. The bottom cover (66) is connected to the lower end of the outer wall (65) and the bottom step (
The inner end of the lower surface of 52) is fitted in a concave and convex manner and is welded, and this concave and convex fit improves sealing performance. The outer wall (65) has a tapered shape with a thicker diameter at the bottom so that the lower part of the sealed space is wider than the upper part, and the liquid (65)
8) is allowed to concentrate downward and prevents the liquid from rising upward.

As shown in FIGS. 6 to 9, 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 between each stage. A gap (69) is formed and has spring properties.

This spiral body (30A>) is formed by a mold so that the gap (69) is in an expanded state as shown in Fig. 6 when no force is applied in the direction of contraction in the direction of the cylinder axis (natural extension state). So, when M(61) is closed, it is compressed and the gap (
69) becomes the most contracted state, and when a force is applied in the direction of extension of the cylinder axis from the state shown in the same figure, the gap becomes even larger.
When a force is applied in the horizontal direction, a horizontal shift occurs between the steps, which also causes the gap (69) to expand in the left-right direction. This spiral (30A>
What is the length in the axial direction of the cylinder? <61) Even in the closed state and the naturally extended state, it can be formed longer than the depth (pl) of the cylindrical part (29b), making it easy to take out the filter (30). The length of the helical body (30A) in the axial direction of the cylinder in its natural extended state is such that when stored in the separation cylinder (29), the upper end is at the container lid (29).
The length is such that it touches b).

In addition, the uppermost stage <30a) and the lowermost stage (30b) of the spiral filter (30) are arranged so that the end surfaces (70>(70) are flat surfaces with no steps (excluding the protrusions (82), etc. described later). By configuring this, a large gap cannot be formed between the inner surface of the lid (61) and the inner bottom surface of the cylindrical portion (29b), thereby preventing the outflow of debris.The reason for the above-mentioned change in the height dimensions of the cross section. In this case, it is possible to attach ring-shaped bodies for height adjustment to the top and bottom surfaces of a spiral body with the same cross-sectional shape, or to change the cross-sectional shape with a mold, but in this example, the latter was adopted. The end portion (71) (71〉) is made sufficiently thick in the axial direction of the cylinder to ensure the strength of the end portion, and the end portion (71) (71〉
A protruding piece (72) is provided on the end (71) (71).
) is formed with a groove (73) into which the protruding piece (72) is fitted, and when the filter (30>) is pulled up, a slight force is applied to the end (71) (71). The ends (71), which have small cross-sections, are constructed so as not to be damaged, and when a predetermined force is applied, the projecting pieces (71)
2) and the groove (73) are disengaged from each other, the corner portions are rounded. Since this locking is performed on the outer peripheral side of the filter (30), there is less adhesion of debris and cleaning is easy.

In addition, the spiral body (30A) is formed so that the outer diameter is slightly smaller than the inner diameter (tip of the protrusion (57)...) of the cylindrical portion (29b), and the outer circumferential surface (74) becomes the protrusion (57)... As shown in FIG.
By forming 5a)<75a), the rotation of the separation tube (29) allows the scum to be accumulated from below first, and also facilitates the removal of the scum from the filter in the downward direction. still,
In the embodiment, the filter (30) is formed to have a larger diameter toward the top and bottom in order to eliminate the vertical directionality, but if it has directionality, it would have a taper that increases in diameter from the top to the bottom. It is sufficient if it is formed on a surface.

In addition, the cross-sectional shape of each stage of the spiral body (30A>
), thereby further reducing the flow resistance of the liquid flowing out from the gap (69), and making the inner surface (76b) a flat surface to facilitate the movement of waste. Note that the form of this notch is not limited to that shown in the drawings. Furthermore, if it is not necessary to improve the mobility of debris, the inner surface may be curved.

Further, referring to FIG. 4, the spiral body (30A> forms a liquid flow gap (69) between each stage, and also forms flat surfaces (77a) (77b) on the surfaces forming the gap, and the lower surface of the lid (61). A liquid flow gap (
79) (80) are formed. This gap is a constant value (for example, 0.4 mm) between each stage when the lid is closed as shown in the figure.
In order to prevent the spiral gap (69) from becoming narrower, the flat surface (7
7b) are formed with spacing protrusions (81) of the same height over substantially the entire width in the radial direction at equal intervals in the longitudinal direction of the gap (69). ), the spiral body (30A>) has protrusions (8
1). Protrusions (82) for maintaining the distance are formed at the same height as . These protrusions (81)..., (82)
Because of this, the ease of liquid outflow is approximately equal throughout the vertical direction of the filter. In addition, the latter protrusion (82)... is provided on the lid (61) and the cylindrical portion (30A) instead of being provided on the spiral body (30A).
29b) side, the former protrusion (81)...
may be provided on the upper surface side of the spiral body (30A). Further, the protrusions (81), (82), etc. may be knurled protrusions.

Further, the spiral body (30A) has a cylindrical portion (29b) and a lid (
61>, rotation is prevented by concave-convex engagement. That is, at the uppermost and lower stages of the spiral body (30A), substantially V-shaped engagement grooves (83) having the same shape are provided at the outer corners of the spiral body (30A).
. . . are formed in large numbers over a predetermined angle range (approximately 60 degrees in this example) at the target position, and the upper groove (83) . The lid (61) is fitted with approximately V-shaped protrusions (84) formed at predetermined angle intervals (approximately 60 degrees in this embodiment).
The rotation stopper was removed between the 1III (83〉
The protrusions (59) of the cylindrical portion (29b) fit into the . . . , thereby preventing rotation between the cylindrical portion and the separation tube (29).

In addition, the spiral body (30A>
9b) and set so that when the separation tube (29) is allowed to rotate, the diameter will expand, i.e., for example, the separation tube (29)
When the direction of rotation is counterclockwise (X) when viewed from above, the direction of winding from top to bottom is clockwise when viewed from above. If you wind it in the opposite direction to this winding direction, the lid (61
) and the engagement with the coil (30), so as the separation # (29) rotates, the diameter of the helical body (30A) contracts and at the same time the axial length of the cylinder increases. acts,
This force acts as a force that tries to remove the lid (61, >), and in some cases, there is a risk that the engaging part between the ! (61) and the separation tube (29) may be damaged and the lid (61) may be blown off. The winding direction in this example changes as the separation head (29) rotates.
0A), the force acts in the direction of expanding the diameter and shortening the length in the axial direction of the cylinder, so there is no such drawback and the locking structure of the lid (61) can be simplified.

Further, the lid (61) is fully fitted into the large diameter portion (60) at the upper end of the cylindrical portion (29b) as shown in FIG. 4 and FIGS. 10 to 12, making it impossible to remove the filter (30). Stop and filter (30)
The structure is designed to prevent debris accumulated on the inner circumference from flying out. (61a) is a cylindrical vertical part in contact with the large diameter part (60), and protrusions (85) are provided at equal intervals on the outer peripheral surface, and between the protrusions (85), the large diameter part (60)
The longitudinal groove (86a) through which the protrusion (62) passes and this groove (8
6a) and a transverse groove (86b) in which this protrusion engages.
A large number of "shaped grooves (86) are formed at equal intervals, and the inner circumferential surface (87) is formed in a tapered shape that expands downward, and a longitudinal protrusion that abuts the outer circumference of the upper end of the spiral body (30A). A liquid tJt passage gap (89) is formed between the spiral body (30A>) and between the inner surface of the large diameter portion (60) and the vertical portion (61a). Liquid flow gaps (90) and (91) are also formed in the spiral body (30A).
92), the lower surface presses the upper end surface of the filter (3o), and the peripheral edge of the opening (93) acts to prevent debris from flying out.

Also, referring to FIG. 2, the container lid (21b) is cutter (
A material input M (44) is integrally installed vertically so as to face an off-center part of 38), and a cutter (3B) is attached to its periphery.
A regulating plate (41) integrally protrudes in the horizontal direction so as to cover substantially the entire surface of the plate. The outer edge of the regulating plate (41) is bent downward to form a hanging part (41a) located outside the recutting blade (4o) and facing the extension part (42). This hanging part (41a) is formed with one or more slits for concentrating the material and protruding from it, and there are projections (94) cut on the outer circumferential surface for holding down the material...
are integrally formed. (95) is the material input tube (41)
The push rods (96) that are inserted into the tube to push the material in are protrusions formed obliquely in the direction to discharge the excess waste to the outside of the separation tube when excessive waste is accumulated.

In addition, the container lid (21b) is attached to the main body case (21b) as shown in Figure 1.
2) with a clamp device <97) attached to the container (21
a) is pressed onto the main body case (2) with the lid closed.

(II[) About the liquid extraction part (C) (u9) A cup that receives the liquid from the llffi outlet (25), which has an approximately triangular shape in plan, and is located at the front corner of the main body case (2) and has an approximately triangular shape in plan. It is placed on the formed low step part (9), and a handle (120>) is provided at the corner part to facilitate removal from the front side of the main body.

Next, the operation of the above embodiment will be explained. Before liquid generation, after engaging the protrusions (72) (72) at the starting end of the filter (3o) in the extended state as shown in FIG. ). Then, while compressing the filter (30), the lid (61) is attached to the cylindrical part (29b).
into the large diameter part (60) of the
? Insert Aff (86a)... into the horizontal groove (86b) and turn 1 (61) clockwise (opposite to the rotational direction of the separation cylinder (29)) when viewed from the soil, and then insert the protrusion (62)... By positioning the cylindrical part (29b) at the back of the horizontal groove (86b)...
b) Bind to. In this state, the filter (30) is shrunk and popped out as shown in FIG. 4. and,
The projections (82) on the upper end create a gap (79) between the inner surface of the lid (61) and the upper end surface (70) of the filter (30), and the projections (81) create a gap (69) between the projections on the lower end. (82)... maintains the interval IJ (80) at a constant interval.At the same time, the protrusion <59)... and the groove <8 at the lower end
3〉・ The lower end of the filter (30) becomes cylindrical (
29b), and the protrusion (84)... and the groove at the upper end (
83>..., the upper end of the filter (30) is locked to the lid (61), and the filter (30> is prevented from rotating vertically).

Next, the container lid (21b) is closed on the receiver (21a), and the clamp device (97) is rotated to engage the lid (21b>) to complete the juice liquid production preparation state.Then, the electric motor is turned on. It is driven to feed materials such as fruits and vegetables into the input cylinder (44) and push them in with the push rod (95).Then, the materials are grated by the grater blade (39), but the material cannot be grated. For large materials such as leather, use the recutting blade (40)...
The particles are cut into small pieces and blown outward in the horizontal direction through the gap between the regulating plate (41) and the base (29a) or the notch in the hanging portion (41a), and are 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 gap (80) and <69). reaches the inner periphery of the cylindrical part (29b), and the protrusion (57)...
The further water that has moved upward through the flow gap (58) formed by the above flows out of the separation cylinder (29) through the flow gaps (90) and (91) between the lid (61) and the cylinder part (29b). It can be received in the container (21a). This liquid is transferred to the outlet (2
5) and is received by the cup (119).

On the other hand, the waste portions are accumulated sequentially from the inner lower end (H) of the filter (30) while being pressed by the holding projection (41a), resulting in the accumulation state as shown in FIG. 13. When the material is further cut, the material to be cut is accumulated in the inner upper half of the filter (30), and the liquid separated from the material to be cut in the lower part of the horizontal part (61b) of the lid (61) is accumulated in the gap ( 79)-(89)-
(90)-(91) and (69)-(90)-(91)
The liquid flows out through the separation cylinder (29). The outflow of this liquid is made smooth by tapering the inner circumferential surface (87) of the lid (61). Furthermore, the material is cut and the lid <61
) When the waste can be accumulated inside the opening (93> diameter), the scum is discharged to the outside of the separation cylinder <29) by the protrusions (96).

During this juice generation, the debris adhering to the inner periphery of the filter (30) tries to expand the liquid outflow gap (69) due to centrifugal force, but the upper end of the filter (30)
Because it is held down by As a result, the waste is prevented from flowing out of the filter 30 through the gap (69), and a large amount of waste is prevented from being mixed into the liquid.

To remove the scum after such juice production, first stop the electric motor, remove the clamping device, and remove the container M (21
b>Remove. Then, rotate the lid (61) to
9b), the filter (30) expands due to its own elasticity as shown in Fig. 13, and the upper end becomes the cylindrical part (29b).
Projects upward from the upper end. By holding this protrusion and pulling it upward, the filter (30) can be easily taken out of the separation tube (29).The filter (30) has debris (K) attached to the lower part of its inner periphery.

By holding both ends of the filter (30), expanding and contracting it, and shifting it laterally as shown in FIG. 14, the mass of waste (K) can be easily removed from the inner periphery of the filter.

In addition, fibers etc. remaining in the gap (69) are removed from the gap (69).
Since the spacing expands due to its own elasticity, it can be easily washed away in this expanded state by washing with water.

Also, in order to clean the inside of the separation tube (29), use the stand (29)
a) and the connector (11), and remove the separation tube (29).
) After removing the ring body (2), you can wash the inside with water.
9c) from the base (29a) and separate the base (29a) and the cylindrical part (29b), making it easier to clean.

In the above example, the spiral body (30A) is divided into minutes m1s (
29) The spiral body (
By giving spring properties to the filter (30A), the liquid flow gap (69) expands when the filter (30) is taken out, making it easier to remove debris and cleaning. When the upper end of (30A) comes into contact with the container lid (21b), the lid (6
1) If you forget to close the door and drive it by mistake, a contact sound will be generated, which has the advantage of making it easier to notice the abnormality.

Moreover, since the filter (30) protrudes upward from the upper end of the cylinder part (29b) when it is installed in the cylinder part (29b) and during #JM, it becomes easy to take out the filter (30). Furthermore, by forming a large-diameter portion (60) at the upper end of the cylindrical portion (29b) and having a space between it and the outer periphery of the upper end of the filter (30) so that a finger can be inserted, the filter (30) can be easily inserted. If you want to make it easier to remove the filter, insert the filter (3) before closing the lid.
0) is attached to the tube portion (29b), it can be seen at a glance whether the Lyruta (30) is attached or not, thereby preventing incorrect use due to the Lyruta (30) not being attached.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and for example, the filter (30) may be configured to be in the most contracted state when no force is applied. Furthermore, a filter (30)
The spiral body (30A> may be formed hollow, and the cross-sectional shape may be a shape other than that shown in the figure. In this hollow case, the spiral body (30A>) can be formed by extrusion molding. Also, the cylindrical part (29b) protrusion (57)・
It is also possible to form a concave groove (not shown) in the filter (3o) that limits the ridges (57) so that the protrusions (57) also serve to prevent the filter from rotating. Further, the protrusions 57) may be discretely formed protrusions.

(v) Effects of the Invention According to the present invention configured as described above, by allowing the spiral body to expand and contract in the direction of the cylinder axis or by shifting it in a direction perpendicular to the direction of the cylinder axis, the gap between the liquid flow gaps and gaps can be increased. This makes it easy to separate the waste from the filter, and it also makes it possible to clean the filter with a large liquid flow gap, making it easy to clean the filter and always keep the filter clean. Can be kept clean. In addition, since the winding direction of the spiral body is set in the direction in which its diameter expands due to the rotation of the centrifugal separation cylinder, a force acts on the lid holding means so that the length of the spiral body in the cylinder axis direction is reduced by the rotation of the centrifugal separation cylinder. No excessive force is applied and the lid holding means is not damaged.
This has great effects such as simplifying the structure of the lid holding means.
