Description

Description: TECHNICAL FIELD The present invention relates to a juicer that squeezes juice from a material crushed by a cutter with a centrifugal separation basket, and more particularly, to centrifuging the scraps 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.

Specifically, a configuration is considered in which a bottomed tubular casing case is used, and a lower opening is formed on the lower wall of the casing case along the upper flange of the centrifugal separation basket.

However, if the clearance between the lower opening formed on the bottom wall of the waste case and the brim of the centrifuge basket is reduced in order to collect the waste efficiently, the amount of waste accumulated from the periphery of the waste case toward the inside will be reduced. Eventually, there is a problem that it sticks out from the lower opening and comes into contact with the brim, and brakes the rotation of the centrifugal separation basket.

The present invention has been made in view of the above problems, and provides a juicer capable of preventing a braking effect due to accumulated dust while having a structure for discharging the dust to the outside of a centrifuge basket. To aim.

Means for Solving the Problems In order to achieve the above object, the juicer according to the present invention is provided with an inverted conical filter section that opens upward in a centrifuge basket, and is configured to discharge the scraps to the outside of the basket. The separated basket is rotatably supported in the saucer serving as the juice flow path.

In addition, a bottomed tubular casing case with a lower opening formed in the lower wall is arranged such that the lower opening is formed along the upper edge of the filter portion along the outer periphery of the brim portion, and the upper end side of the centrifugal separation basket is formed. It is configured to collect the dust particles scattered from the.

Furthermore, a plurality of step surfaces that fall inward toward the inner peripheral side along the radial direction of the centrifugal separation basket are formed on the outer peripheral edge of the brim so as to face the front side in the rotational direction, and at the rear side in the rotational direction from the outer peripheral side of one step surface. It is configured to smoothly continue to the inner peripheral side of the next step surface on the side.

Action Since the juicer according to the present invention is configured as described above, the dust accumulated in the dust case does not come into full contact with the outer circumference of the brim portion of the centrifugation basket.

Embodiment Hereinafter, the present invention will be described with reference to the drawings. 1 to 7 show an embodiment of the present invention.

As shown in FIGS. 2 and 3, this juicer comprises a main body 100 containing a motor 110, a saucer 200 for collecting juice that has passed through the filter portion of a centrifuge basket, a cutter 310 and an inverted conical shape. A centrifuge basket 300 provided with a filter unit 320, a bottomed cylindrical dust case 400 for collecting dust scattered from the upper end side of the centrifuge basket 300, and a throw-in cylinder 510 opening facing the cutter 310 are formed. It has a lid body 500 that has been opened.

As shown in the figure, each part is fixed.

Hereinafter, each component will be described in detail.

In FIG. 2, the motor 110 is fixed to the upper wall of the casing that covers the outer periphery of the main body 100. Output shaft 111 of motor 110
Is projected upward from the upper wall of the casing, and a rotary plate 112 is fitted and fixed to the tip portion thereof.

Further, a placing table portion 130 is formed on one side of the main body 100 so that a side wall is cut out, and a semi-cylindrical juice case 140 is placed on the placing table portion 130.

The saucer 200 that collects the juice is in the shape of a dish that opens upward, has a circular central opening 210 that exposes the rotating plate 112 in the center of the bottom wall, and the juice case 130 is provided on one side of the other bottom wall. An outlet 220 is formed so as to face from above.

Now, the centrifuge basket 300 arranged inside the saucer 200 is
A resin coupling part 330 is mounted on the rotary plate 112 and rotatably supported. As shown in the enlarged view of FIG. 1, a metal cutter 310 for crushing the material is provided on the upper surface of the coupling portion 330, and the lower end of the metal mesh filter portion 320 is provided in the peripheral portion. It is embedded.

The above filter part 320 is formed in an inverted conical shape,
Its upper end is a resin brim portion 34 formed along the upper edge.
Embedded within 0.

As shown in FIGS. 1, 4, and 5, the brim portion 340 includes a base portion 341 that holds the filter portion 320, and an outer peripheral flange 342 that is formed on the outer peripheral side of the base portion 341 by one step.
And a lower flange 343 extending downward from the outer peripheral flange 342.
And a wedge-shaped protrusion 344 formed at a position that divides the outer peripheral flange 342 into four in the circumferential direction.

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

The stepped surface A, which is a discontinuous portion of the outer peripheral flange 342, faces the rotational direction in the radial direction and inclines upward toward the rear side in the rotational direction with respect to the circumferential direction. It has the effect of flipping up the scraps that are about to fall off.

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.
Slide plates 440,44 slidably arranged along
0 (see FIG. 7) and has a flat cylindrical shape as a whole when assembled. Each semi-cylindrical member 420, 42
0 has an upper wall 450 that forms an upper opening 451 when the whole is cylindrical, and a lower wall 460 that forms a lower opening 461 having a diameter larger than that of the upper opening 451.

A knob portion 441 is formed on one end side in the longitudinal direction of the slide plate 440 so as to project to the outside of the side wall 430 when mounted on the waste case 400, and a scraping rib 442 and a recess 443 projecting inward are formed on the other end side. Has been formed.

On the side wall 430 of the waste case 400, there is provided a stopper 431 (see FIG. 2) that engages with the concave portion 443 of the slide plate 440 when the slide plate 440 is mounted on the parting line portion on one side to position the slide plate 440 on one side. The split line portion on the other side is notched so that the knob portion 441 of the slide plate 440 is projected.

As shown in FIG. 4, an inner flange 462 protruding downward along the periphery of the lower opening 461 is formed on the lower wall 460 of the waste case 400, and the inner flange 462 and the side wall 430 are provided with 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.

The upper end of the lower opening 461 of the dust case 400 is set to the second
As shown in Fig. 4 and Fig. 4, the brim 3 of the centrifuge basket 300
It is configured to be arranged along 40. Further, in this example, the upper end portion of the lower opening 461, that is, the upper surface of the lower wall 460 is located in the middle of the upper and lower ends of the brim portion 340, and the lower opening 4
The clearance between 61 and the brim portion 340 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 minimize the falling of dust from the dust case 400.

The lid 500 has a substantially hemispherical shape as shown in FIG. 3, and a piston 520 for pressing the loaded material against the cutter 310 is detachably inserted into the loading cylinder 510.

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

When squeezing the juice, after the setting as shown in FIG. 2 is completed, the power is turned on and the motor 110 is rotated to rotate the centrifugation basket 300.

Next, pull out the piston 520 and put the ingredients such as fruits, vegetables, etc., cut into appropriate size into the charging cylinder 510 to
Press from above. As a result, the cutter 310 crushes the material, and the crushed material reaches the filter section 320 while being extended 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.

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.

Also, since the stepped surface is provided on the outer peripheral flange 342 of the brim portion 340, even if the accumulated debris protrudes from the lower opening 461, it does not entirely contact the brim portion 340 and is less affected by the braking effect. ing. Further, since the step surface A is inclined upward, the scrap component abutting on the step surface A can be flipped up toward the upper part of the scrap case 400, and not only the braking effect due to the scrap component is prevented but also the volume of the scrap case 400 is increased. The effective use of can be achieved. 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, and the knob 441 of the slide plate 440 is held and the slide plate 440 is held.
To remove the scraps.

After roughly removing the dust by this 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.

EFFECTS OF THE INVENTION As described above, according to the present invention, a plurality of step surfaces are provided on the outer circumference of the flange portion of the centrifugal separation basket, and the step surfaces are arranged on the outer side and the inner side from the front side toward the rear side in the rotation direction. Since the and are smoothly connected, even if the scrap component protrudes from the lower opening of the scrap case, the brim portion does not come into contact with the scrap component as a whole, and is unlikely to be affected by the braking effect due to the contact with the scrap component.

Further, when the step surface is inclined so as to be directed upward in the rotational direction, the contact scrap can be flipped upward, so that the braking phenomenon can be prevented and the capacity of the scrap case can be effectively used. be able to.

Furthermore, when the stepped surface is enlarged by providing a protrusion on the stepped surface, the effect of jumping up the scrap can be further enhanced.
