Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a juicer that grinds the material to be cooked with a rotating cutter and separates it into juices and grounds in a centrifugal separation basket.

[Conventional technology]

FIGS. 8 and 9 show a conventional juicer. In the figure, 1 is a base having a bottle holder 2 and a built-in motor (not shown), and 3 is the holder 2.
4 is a squeeze case that has a juice outlet 5 and is removably placed on the base 1; 6 is a flat dregs case receiver formed integrally with the squeeze case 4; , 7 is a centrifugal separation cage housed in the aperture case 4 and rotated at high speed by the power of the motor, 8 is a case ring detachably fitted to the upper edge of the aperture case 4, and 9 is detachably attached to the aperture case 4. 10 is a clamp that fixes the lid 9 to the base 1 by sandwiching the aperture case 4 and the case ring 8; 11 is a clamp 10;
The pivot 12 is a handle that is held between the waste case receiving part 6 and the case receiving part 13 of the lid 9 facing it, so that it can be inserted and removed from the side with elastic deformation of these quantity receiving parts. 14 is a dregs case, 15 is a dregs inlet of the dregs case 12, 16 is a case receiving part 13
These ribs are provided on the lower surface and overlap the inner surface of the upper edge of the waste case 12.

The side surfaces of the squeeze case 4 and the sieve case 12 are continuous with each other without forming any steps or dents, and the sieve case 12
In order to reduce the size of the centrifuge cage 7 by moving it closer to the centrifuge cage 7, the wall portion 4 of the squeeze case 4 on the side where the dregs case is attached is
a and the inner wall 12a of the dregs case 12 on the squeeze case side are each formed in an arc shape. For this reason, as shown in FIG. 9, the circumferential wall of the aperture case 4 is non-circular, and an arcuate circumferential wall portion 4b is located approximately at the same distance from the centrifugal cage 7.
The similar arc-shaped peripheral wall portion 4a means the aperture case 4.
The corner portions 4c are formed to form a corner portion 4c that protrudes outward.

When the juice is squeezed in the conventional structure as described above, the juice squeezed by the centrifugal separation cage 7 rotating in the direction of the arrow in FIG. It scatters along the centrifugal direction from the upper edge 7a of the separation basket 7, hits the inner peripheral surface of the aperture case 4, and then flows out.

[Problem that the invention attempts to solve]

However, as already mentioned, since the aperture case 4 is non-circular, the wind formed in the aperture case 4 due to the rotation of the centrifugal separation cage 7 most strongly impinges on the inner surface of the corner 4c. Therefore, due to the force of the collision, a part of the juice leaks to the outside from the fitting part between the aperture case 4 and the case ring 8, which is fitted to the case 4 with a small fitting allowance 8a. I was afraid.

[Means for solving problems]

The present invention is implemented in a juicer equipped with an aperture case that accommodates a centrifuge cage, and a case ring that is detachably fitted onto the upper part of the aperture case, and the peripheral wall of the aperture case is connected to the centrifugal separation cage. It is formed to have an arc-shaped peripheral wall portion located at approximately the same distance from the car, and a protruding peripheral wall portion that is continuous with this peripheral wall portion and projects outward of the aperture case, and is integrally attached to the case ring downwardly. The above-mentioned conventional problems are solved by providing a structure in which a windshield portion is provided that protrudes and overlaps the inner surface of the protruding peripheral wall portion.

[Effect]

In the juicer having the above configuration, when the case ring is fitted to the aperture case, the windshield part of the case ring overlaps the part of the aperture case where the wind collides most strongly, that is, the inner surface of the protruding peripheral wall part of the aperture case. Cover the inner surface of this wall. Therefore, the sealing performance at the fitting portion between the aperture case and the case ring is improved, and leakage of juice to the outside through the fitting portion during use is prevented. In other words, the wind that heads toward the protruding peripheral wall of the throttle case and the youth carried by this wind collide with the windshield that overlaps the inner surface of this protruding peripheral wall, so the wind flows along this windshield. The youth is moved upward by the force, and the youth is prevented from moving upward along the inner surface of the protruding peripheral wall portion. Since the windshield part is integrated with the case ring, it is possible to isolate the youth moving along the windshield from the fitting part of the case and case ring, and also to isolate the youth that moves along the windshield from the fitting part of the case and case ring. Also, due to the resistance between the overlapping portion of the windshield portion and the protruding peripheral wall portion, the youth is prevented from reaching the fitting portion. Therefore, the waste carried by the wind is prevented from passing through the fitting portion between the aperture case and the case ring, and leakage to the outside is prevented.

A pair of clamp receivers 60 are integrally protruded from the fitting portion 58, and a clamp 61 attached to the base 21 can be releasably hooked onto these. Due to the clamping action of the clamp 61, the squeeze case 27 is clamped between the base 21 and the lid 56, and the dregs case 47 is clamped between the squeeze case 27 and the lid 56. . In addition, 62 in FIG. 2 is a pivot of the clamp 61.
Further, a material input tube 63 whose lower end is close to the upper surface of the cutter 45 is integrally formed on the top plate portion 57;
A material pushing rod 64 is removably inserted into this cylinder 63.

It is equipped with a youth bottle lid 66 that can be freely fitted. The youth bottle lid 66 is formed with a U-shaped youth socket 67 that fits into the youth outlet 31.

In addition, in the above explanation, the centrifuge cage 43
All other parts except for the filter 44, cutter 45, motor, etc. are made of synthetic resin.

To assemble this adjuster for use, first place the aperture case 27 on the base 21, and then place the case ring 34 on the top of the case 27.
mate. This fitting is determined by the fitting step portion 35. In this case, since the case ring 34 integrally has a downward windshield part 37 that is longer than the fitting rib 36, this windshield part 37 is connected to the aperture case 2.
They are fitted while being guided in advance along the inner surface of the protruding peripheral wall portion 29 of No. 7. Thereby, the case ring 34 can be approximately positioned and fitted, so that the case ring 34 can be easily attached.

Then, by attaching the case ring 34, the protrusion 41 and the second peripheral wall portion 3 of the aperture case 27 are connected.
A fitting groove 42 is formed between the protruding peripheral wall portion 2 and the windshield portion 37 covering the protruding peripheral wall portion 29 along the inner surface of the protruding peripheral wall portion 29.
The tip of the extending portion 37a of the diaphragm 9 is covered with a rib 38 of the aperture case 27.

Next, the centrifugal cage 43 is housed in the aperture case 27, and its coupling ring 46 is fitted into the coupling ring 25 on the base 21 side. Thereafter, the dregs case 47 is inserted from above so that its inner side surface follows the outer surface of the peripheral wall portion 30 of the aperture case 27. Then, the locking recesses 48 on both sides of the dregs case 47 are connected to the locking protrusions 32 on both sides of the aperture case 27.
At the same time, the ring overlapping parts 49 and 50 of the dregs case 47 are exactly fitted into the engaging step parts 39 and 40 of the case ring 34, respectively. At the same time, the fitting protrusion 55 provided on the collar 53 of the dregs case 47 is fitted into the fitting groove 42, and the protrusion 54 of the dregs case 47 is fitted onto the outer surface of the protrusion 41 of the case ring 34. Overlap.

Next, the squeezing case 27 and the combing case 47
The lid body 56 is fitted over both. Due to this fitting, the dross case side fitting portion 59 of the lid body 56
The outer surface of the flange 52 of the dregs case 47 overlaps with the inner surface of the case ring 34 in a surface contact state, and the presser flange 58a of the aperture case side fitting portion 58 overlaps the annular stepped portion 35 of the aperture case 27. It is in contact with a portion along the peripheral wall portion 28.

Finally, the clamp 61 of the base 21 is rotated to engage the clamp receiver 60 of the lid 56. As a result, the aperture case 27 is sandwiched between the lid body 56 and the base 21, and the dregs case side fitting portion 59 of the lid 56 presses the stepped portion 51 of the dregs case 47, so that the dregs case 47 is sandwiched between the aperture case 27 and the lid body 56.

As the lid body 56 is fixed as described above, the presser flange 58 a clamps the portion of the case ring 34 along the peripheral wall portion 28 between it and the annular step portion 35 , and the scrap case 47 is At the same time as the pinching, the ring overlapping portion 4 of this case 47
9 and 50 hold down the dregs case mounting side of the case ring 34 and sandwich it between the case ring 34 and the annular stepped portion 35.

After the above assembly, the youth bottle 65 is inserted from the side and placed on the bottle mounting base 23 of the lid base 21, and the youth outlet 31 of the aperture case 27 is fitted into the youth socket 67. The motor is operated by operating the operation switch section 26. Then, in this state, the material to be cooked is put into the material input cylinder 63, and the material is rotated at high speed (per minute).
The material is pressed with a material pushing rod 64 against the cutter 45 of the centrifugal separation cage 43, which is rotating at about 10,000 rotations. Then, the material is ground into particles by the cutter 45, and the material particles rise along the inner surface of the filter 44 after being moved outward by centrifugal force. Therefore, the juice squeezed in this filter 44 is taken out between the outer surface of the filter 44 and the inner surface of the aperture case 27,
The material particles, that is, the dregs dehydrated by the above-mentioned juice extraction, pass over the upper edge of the filter 44 and are stored in the dregs case 47 from the upper surface of the case ring 34 through its inlet 47a.

The juice squeezed out of the filter 44 of the centrifugal cage 38 as described above collides with the squeeze case 27 and flows down along its inner peripheral surface to reach the juice outlet 31. Since the circumference is non-circular, if there were no windshield portion 37, the protruding circumferential wall portion 29 would obstruct the flow of wind within the aperture case 27, and the wind would most strongly collide with this protruding circumferential wall portion 29. . However, since the inner surface of the protruding peripheral wall portion 29 is covered with the windshield portion 37 of the case ring 34, the wind does not collide with the inner surface of the protruding peripheral wall portion 29 on the side where the aperture case 27 and the case ring 34 fit together. , can be obstructed by the windshield part 37.

Therefore, the youth carried on the wind,
Due to the force of the collision, the area between the fitting part of the case ring 34 and the aperture case 27 on the case mounting side is
It can be passed upwards to prevent leakage. In addition,
Since the windshield portion 37 has a considerable length (about 20 mm) and is overlapped with the inner surface of the protruding peripheral wall portion 29,
It goes without saying that the resistance provided by these overlapping portions can prevent the air flow from rising due to the force of the wind impinging on the attachment 29 on the lower side of the windshield portion 37.

Furthermore, in this embodiment, since the tip of the extending portion 37a provided in the windshield portion 37 on the side of the waste inlet 47a is covered with the rib 38 provided on the wall portion 29a of the protruding peripheral wall portion 29, the above-mentioned extending portion 37a and this are covered. The surrounding wall portion 2 is placed at the joint with the overlapping surrounding wall portion 29a.
It is possible to prevent wind and youth flowing along 9a from entering and leaking to the outside.

Further, separation for cleaning after use can be carried out by reversing the assembly procedure described above.

Although the above embodiment is constructed as described above, the present invention can also be implemented in a juicer in which the dregs case 47 and the aperture case 27 are integrated. others,
When carrying out this invention, centrifuge cages, aperture cases, case rings,
It goes without saying that the specific structure, shape, position, etc. of the windshield etc. are not limited to the one embodiment described above, and can be configured and implemented in various ways.
