Description

TECHNICAL FIELD The present invention relates to a juicer for squeezing juice from a material crushed by a cutter with a centrifugal separation basket, and more particularly, to centrifuging the residue separated from the juice. The present invention relates to a juicer that is scattered from a separate basket and accumulates in a waste case.

2. Description of the Related Art Conventionally, as a juicer, a so-called in-casing type in which a tubular filter body is arranged in a bottomed tubular centrifugal separation basket is used.

However, in this type of juicer, since the dust separated from the crushed material is laminated on the inner surface of the filter body, the filter is likely to be clogged, and the amount of dust that can be accumulated is large. There is a problem that the amount of juice that can be continuously squeezed is small because the amount is small.

Therefore, recently, there has been proposed a juicer having a configuration in which by using a centrifuge basket having a cutter and an inverted conical filter section, the juice after squeezing the juice is successively discharged out of the centrifuge basket. There is.

Since this type of juicer has a peculiar structure of scattering dust, it is necessary to provide a dust case for accumulating the scattered dust.

However, if only a saucer-like dregs case is provided around the centrifuge basket, the dregs scattered upward adhere to the lid formed with the throw-in cylinder to deteriorate the cleanability or mix with the juice component. It may deteriorate the quality of juice.

The present invention has been made in view of the above problems, and it is possible to prevent deterioration of the quality of juice without deteriorating the cleaning property while adopting a configuration in which the waste is discharged to the outside of the centrifugation basket. Intended to provide a juicer.

The outer peripheral flange 342 is shaped so as to gradually enter the inside from the one protrusion 344 toward the rear protrusion 344 in the rotation direction R with respect to the maximum outer circle indicated by the broken line in FIG. ing.

The step surface A, which is a discontinuous portion of the outer peripheral flange 342, faces the rotational direction in the radial direction and is inclined upward in the circumferential direction toward the rear side in the rotational direction. It has the effect of bouncing up the scraps that are about to fall from the top.

Although it is possible to form the step surface A only by the step portion of the outer peripheral flange 342, in this example, the step portion A is formed in the vertical direction from the outer peripheral flange 342 by forming the protrusion 344 in the discontinuous portion. Along with extending the outer peripheral flange 3
The stepped surface A is configured to extend not only above the outer peripheral side of 42 but also above the outer peripheral flange itself, thereby further enhancing the above-mentioned flipping effect.

As shown in FIG. 6, the waste case 400 includes symmetrical semi-cylindrical members 420 and 420 rotatably connected through two hinges 410 and 411, and side walls 430 of the respective semi-cylindrical members.

Also, in this waste case 400, each semi-cylindrical member is shown in FIG.
As shown in FIGS. 8 and 9, in the state where they abut and face each other, the overall shape is a flat cylindrical shape. Each of the semi-cylindrical members 420, 420 has an upper wall 450 forming an upper opening 451 when the whole is made cylindrical, and a lower wall 460 forming a lower opening 461 having a diameter larger than that of the upper opening 451.

In this example, the upper opening 451 through which the insertion tube 510 is inserted is formed so as to have a small gap with the insertion tube 510 as shown in FIG. As will be described later, if this gap is as small as possible, it is possible to prevent scattering of dust outside the dust case 400.

As shown in FIG. 7, the slide plate 440 is elastically formed so as to keep a curve having a larger radius of curvature than the side wall 430 of the waste case in the natural state, and one end side in the longitudinal direction at the time of mounting on the waste case 400. A knob portion 441 protruding to the outside of the side wall 430 is formed, and a scrap drop rib 442 and a recess 443 protruding inward are formed on the other end side.
Reference numeral 444 is a fixed piece, and a knob portion 441 (not shown)
It is similarly provided on the lower side of.

The side wall 430 of the waste case 400 is formed with a stopper 431 that engages with a recess 443 of the slide plate 440 when the slide plate 440 is mounted on one side of the dividing line and positions the slide plate 440 on one side (first). (See Figure 1).

Further, the split line portion on the other side is notched so that the semi-cylindrical portions 420, 420 do not abut each other when the casing case 400 is made cylindrical, and the knob portion 441 of the slide plate 440 is projected from this portion. It is configured. Further, the side wall 430 of the cutout portion bulges outward from the other portions, and a guide portion 432 for sandwiching the slide plate 440 between the side wall 430 and the side wall 430 is provided between the upper and lower walls on the inner peripheral side. (See FIG. 9). It should be noted that the waste case 400 is provided with a fixing projection 470 that engages with the fixing piece 444 and fixes the slide plate 440 when the slide plate 440 is mounted (see FIG. 1).

As shown in FIG. 3, an inner flange 462 protruding downward along the periphery of the lower opening 461 is formed on the lower wall 460 of the dust case 400, and the inner flange 462 and the side wall 430 have an inner portion at an intermediate portion. An outer flange 463, which has a smaller protrusion amount than the flange 462, is formed so as to protrude downward. In addition, these flanges are all splashes of the juice that has passed through the filter portion 320 of the centrifuge basket 300 to other than the saucer 200,
It has an action to prevent outflow.

Reinforcing ribs 462a are provided on the inner wall of the inner flange 462 over the entire circumference, and a step is formed at the lower end of the outer flange 463 so that the inner peripheral side projects one step from the outer peripheral side. There is.

When this waste case 400 is placed on the saucer 200, the side wall 430 of the waste case 400 fits into the outermost peripheral wall 230 of the saucer 200 as shown in FIG.
Positioning in the horizontal direction is made by fitting with 233, and positioning in the vertical direction is made by contacting the tip of the outer flange 463 with the second step portion 232.

Here, from the lower wall 460 of the waste case 400 to the outer flange 463
Since the drop to the lower end of the step is set to be larger than the drop of the step portion 233, the lower wall 460 of the waste case 400 maintains a predetermined distance from the first step portion 231, and the first wall between them is A space S ₁ is formed. Further, a second space portion is provided between the lower end portion of the outer flange 463 and the second step portion 232 and the step portion 233.
S ₂ is formed.

The upper end of the lower opening 461 of the waste case 400 is along the brim portion 340 of the centrifugal separation basket 300 as shown in FIGS. It is arranged to have. Furthermore, in this example, the lower opening
The upper end of the 461, that is, the upper surface of the lower wall 460 is located between the upper and lower ends of the brim portion 340, and the lower opening 461 and the brim portion 340.
The clearance between and is set so small that it does not hinder the rotation of the centrifugal separation basket 300, and the configuration is such that it is possible to suppress the residue falling from the residue case 400 as much as possible.

The lid 500 has a substantially hemispherical shape as shown in FIG. 2, and a notch 520 for avoiding the handle 150 of the main body 100 and an engaging hole 530 for engaging the claw claw 160 are provided in the lower portion thereof. It is provided. In addition, as shown in FIG. 1, the input cylinder 510 is a semicircular cross section in which a cylindrical body having a circular cross section is half-shielded by a diametrical partition plate 511. It is formed so as to eccentrically face the cutter 310 and open. In addition, in the charging cylinder 510, a piston 540 for pressing the charged material against the cutter 310.
Is removably inserted.

In the state where the lid 500 is not engaged with the main body 100, the parts other than the main body are supported by a biasing means (not shown) protruding from the upper casing 122 of the main body 100 at a position raised from the normal use position.

In this state, when the lid 500 is covered from above and the clamp claw 160 of the push-in main body 100 is engaged with the engagement hole 530, each component is set to the normal use position as shown in FIG.

Next, the operation of the juicer configured as described above will be described.

When squeezing the juice, after the setting as shown in FIG. 1 is completed, the power is turned on and the motor 110 is rotated to rotate the centrifugation basket 300.

Next, pull out the piston 540 and insert the fruits, vegetables, etc. cut into appropriate size into the insertion cylinder 510 and
Press from above. As a result, the cutter 310 crushes the material, and the crushed material reaches the filter section 320 while being blown to the outer circumference by the centrifugal force.

In the material reaching the filter section 320, the juice content passes through the filter section 320 and drops to the side of the saucer 200, and the dregs that have become lighter due to the juice content are scattered into the dregs case 400.

Since the centrifuge basket 300 rotates at a high speed, if no measures are taken, the juice that has passed through the filter unit 320 may be wound up by the wind pressure to the dregs case 400 or the like. Conventionally, the volume of the saucer 200 has been increased to distribute the wind pressure, but this juicer has an inner flange 462 that blocks the air passage on the lower wall of the dust case 400.
By centrifuge basket 300 collar part 340 and waste case 400
It is possible to prevent the juice component from rolling up through the gap between the lower opening 461 and the lower opening 461. Therefore, the saucer 200
It is not necessary to increase the volume of the portion, and the juicer can be made compact.

Further, since the inner flange 462 projects below the outer flange 463, the juice component that permeates the upper portion of the filter portion 340 and is scattered falls on the inner flange 462 and joins the saucer 200 and the waste case 400. It does not scatter directly onto the part.

However, the above-mentioned wind pressure may cause the amount of juice in the saucer 200 to rise along the side wall of the saucer 200. But,
In this juicer, the steps 231,232 of the saucer 200 and the waste case
Since two space portions S ₁ and S _{2 are} formed by the outer flange 463 of 400, the capillarity between the mating saucer 200 and the waste case 400 is also prevented, and juice leaks from the joint portion to the outside. Is also prevented.

The juice component dropped on the saucer 200 flows along the saucer 200 and is accumulated in the juice case 140.

On the other hand, the amount of waste accumulates in the waste case 400 from the lower outer circumference to the inner circumference. At this time, if the upper end portion of the lower opening 461 is higher than the brim portion 340, the scraps are likely to be scattered into the saucer 200. Conversely, if it is too low, the accumulated scraps are received.
It is easy for the juice to fall into the inside of 200, and the juice can easily enter the waste case 400. This juicer has a lower opening 461
By arranging the upper end of each of the two in the middle of the upper and lower ends of the brim section 340, both are balanced and the juice can be collected most efficiently.

Since the clearance between the lower opening 461 and the brim portion 340 is small, if the outer circumference of the brim portion 340 is circular, the accumulated scrap will eventually contact the brim portion 340 to brake. However, in the above juicer, since the outer peripheral flange 342 of the brim portion 340 is provided with a step, the brim portion 340 does not come into contact with the scrap as a whole, and is less susceptible to the braking effect. Further, since the step surface A is inclined upward, the scrap case that abuts on the step surface A is scrap case 40.
It can be flipped up toward the upper part of 0, and not only can the braking effect due to the scrap component be prevented, but also the volume of the scrap case 400 can be effectively utilized. Furthermore, by providing the protrusion 344, the flip-up effect is further enhanced.

When juice collection is completed or the dregs case 400 is full, the motor 110 is stopped, the lid 500 is removed, and the dregs case 400 is taken out.

Next, the waste case 400 is folded in two around the hinges 410 and 411 as an axis, the knob 441 of the slide plate 440 is held, the engagement between the fixing piece 444 and the fixing projection 470 is released, and the slide plate 440 is pulled out. At this time, the slide plate 440 is in the natural state and the waste case 4
Since it has a larger radius of curvature than the side wall 430 of 00, the middle portion of the slide plate 440 moves to the inner peripheral side before the recess 443 and the stopper 431 are disengaged when the slide plate 440 is pulled out. As a result, it is possible to separate the scraps attached to the upper and lower bottom walls 450 and 460.

Further, by pulling the slide plate 440, the scraps attached to the slide plate 440 itself can be separated by the guide portion 432. The scrap dropping rib 442 provided at one end of the slide plate 440 prevents only the slide plate 440 from moving, leaving a scrap residue during the above-mentioned pulling operation,
It has the function of moving the scraps together.

After roughly removing the dust by the above operation, the two slide plates 440 are completely pulled out and the dust case 400 and the slide plate 440 are washed with water to remove fine dust.

In this way, the waste case 400 is divided and the slide plate 4 is
By providing 40, the waste case can be quickly cleaned.

In the above embodiment, the lower wall 460 of the waste case 400 is used.
Although only the example in which the upper end portion of the lower opening 461 formed on the upper surface matches the upper surface of the lower wall 460 has been described, the present invention is not limited to this. For example, as shown in FIG. 10, when the upper end of the lower opening 461 formed in the lower wall 460 of the dust case 400 is located above the lower wall 460, the upper end of the cylindrical flange 461 is centrifuged. By arranging the separated basket 300 along the brim portion 340, it is possible to prevent scattering of the scraps to the outside of the waste case 400 and invasion of the juice to the waste case 400 in the same manner as described above.

Further, in the above embodiment, the waste case is configured to be divisible,
Although only the configuration in which the slide plate is provided has been described, these are not indispensable requirements of the present invention. For example, the respective semi-cylindrical portions may be integrated, or the slide plate may not be provided.

EFFECTS OF THE INVENTION As described above, according to the present invention, since the lower opening of the tubular waste case having the upper and lower walls is arranged along the brim portion of the centrifuge basket, scattering of the waste material to other parts is achieved. Can be suppressed.

Also, when this waste case is configured to be divisible,
Even with the above shape, cleaning can be easily performed.

In addition, when the upper opening is formed to have a diameter having a small gap with respect to the throwing-in cylinder, scattering of dust on the lid side can be further reduced.
