Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a juicer that obtains juice by squeezing the material to be cooked.

[Conventional technology]

As seen in the compression-drawing type juicer that has been put into practical use by the applicant in recent years, a conventional juicer can be adapted to allow a juice container to be freely inserted and removed from the bottom of a case that has a juice outlet and a waste storage area. The youth container is arranged to receive the youth from the youth outlet. The youth outlet is opened on the bottom surface of the case, and a downward draining rib is provided on the edge of the mouth.

[Problem that the invention attempts to solve]

However, even though the draining rib is provided at the juice outlet as described above, a part of the juice passing through the juice outlet wraps around the part of the draining rib on the side of the rotation shaft of the juicer, and in the above case, There was a risk that it would travel along the outer bottom surface and reach the stand on which the youth container was placed. The above problem can be solved by making the draining rib longer, but in this case, there will be a large gap between the top of the youth container and the bottom of the case, resulting in an unsightly appearance.
Moreover, this is not a practical countermeasure because it not only increases the overall height and size, but also increases the manufacturing cost. Therefore, the length of the draining rib is small, and the above-mentioned fear has conventionally occurred.

[Means for solving problems]

The present invention provides a juice outlet in the bottom wall of the juice chamber to which the squeezed juice is supplied, and a downward annular draining rib with a protruding length comparable to the thickness of the bottom wall. An upward water-blocking rib is provided on the lower surface of the bottom wall in series with the outlet and extends along the edge of the outlet, and is located on the rotation axis side of the juicer at the edge of the outlet. The above-mentioned conventional problems are solved by protruding from the upper surface and aligning the surface of the water-shielding rib opposite to the rotating shaft side flush with the inner surface of the youth outlet. It is.

[Effect]

In this invention, the squeezed juice flows out from the juice outlet opened in the bottom wall of the juice chamber, and when the force of the juice flow is strong, it does not go around to the rotating shaft side of the juicer, but the force of the juice flows out. When the water becomes weak, the water is blocked by the upward water-shielding rib and bypasses this rib, so that the water can pass through the water outlet from the side as far away from the rotating shaft of the water heater as possible. For this reason, even if some of the youth travels along the lower surface of the bottom wall of the youth room,
This prevents the juice outlet from becoming a hindrance and spreading toward the rotating shaft side of the juicer.

In the above description, all the parts other than the drive coupling 4 of the drive mechanism and other parts whose materials are specially specified are made of synthetic resin.

Next, the operation of this embodiment will be explained.

First, the outer case 8 is fitted into the case fitting part 2 of the regulator main body 1, the engagement protrusion 9 is engaged with the engagement recess 6, and the cylindrical part 10 is fitted into the engagement protrusion 7. The inner case 22 is fitted into the thus supported outer case 8, and positioned by fitting with the fitting step portion 26, the upper annular portion 22a, and the like. Next, the rotary aperture body 29 is fitted into the inner case 22.

Then, the driven coupling ring 34 is inserted into the through hole 18.
and 33 and is engaged in the cylindrical portion 10 with the drive coupling 4 of the drive mechanism. At the same time, the bearing 35 is fitted into the annular step 19 of the outer case 8, and at the same time the packing 36 is pressed against the inner bottom surface of the annular step 19. Note that in this stored state, the lower end of the rotary body 30 of the rotary aperture body 29 is slightly away from the bottom surface of the inner case 22.

Then, after fitting the seal packing 38 into the packing fitting groove 37 of the inner case 22, the case lid 39 is placed in a diagonally shifted position with respect to the outer case 8, and the bearing 40 is attached to the rotating throttle body 29. It fits onto the upper end of the rotating shaft 31 from above. Then, the case cover 39 is attached and fixed to the outer case 8 by rotating the cover 39 counterclockwise. As a result, the rotating shaft 31 of the rotary aperture body 29 is stably supported by the upper and lower bearings 40 and 35 in a dual-supported state, and the seal packing 38 is deflected by pulling the case lid 39 downward at this time. This packing 38 is sandwiched between the upper edge of the inner case 22 and the inner surface of the case lid 39.

Finally, the juice container 11 is placed between the stand 3 of the juicer main body 1 and the outer case 8, the juicer is connected to a power source, and the operating section 5 is then operated to operate the drive mechanism.

In the above-mentioned set state, the user puts the prepared ingredients to be cooked into the material input tube 41, and then uses the material pushing rod 42 to push the ingredients into the rotary squeezing body 29.
Press it onto the top surface.

Then, the material is cut and crushed by the cutter 32 of the rotary aperture body 29 that rotates at a speed of about 3,000 revolutions per minute, and is sent out toward the outer circumference of the rotary body 30. The rotating body 3 of the inner case 22 and the rotary constrictor body 29 is guided downward along the material guide portion 24 of the
It is introduced into the aperture space between 0 and 0.

The cut material introduced in this way (hereinafter referred to as cutting material) is compressed by the outer peripheral surface of the rotating body 30, so that the youth content is extracted.
This juice portion (juice) is filtered by a filter 23 and flows out into the juice chamber 13. Then, this juice portion flows out of the youth outlet 17 and is stored in the youth container 11 disposed below the outer case 8 through the groove 12a. Further, the material waste is sent downward by a spiral groove on the circumferential surface of the rotating body 30, and the waste outlet cover 25 is pushed open from the waste outlet of the inner case 22 against the biasing force of the spring, and the waste is pushed open from the waste outlet of the inner case 22. The waste is discharged to the waste storage section 16 of No.8.

In the compression drawing as described above, until the latter stage, the amount of squeezed youth is large and the force passing through the youth outlet 17 is strong, so a part of the youth is transmitted to the lower surface of the bottom wall of the outer case 8 due to this momentum. There is no. However, in the later stages of compression and squeezing, the force of the youth becomes weaker, so when the youth flows through the youth outlet 17, the youth is blocked by the water-blocking rib 20, and bypasses the rib 20 and passes through the youth outlet 17. be distributed.

In other words, the youth is discharged into the youth container 11 through the youth outlet 17 from the side far from the cylinder portion 10 where the rotating shaft 31 is located.

Therefore, even if part of the youth that has passed through the youth outlet 17 is transmitted along the lower surface of the bottom wall of the outer case 8, the cylindrical portion of the outer case 8 that is located close to the youth outlet 17 The presence of the youth outflow port 17 prevents the youth from being transmitted to the 10 side, and as a result, a portion of the youth flows from the cylindrical portion 10 to the bottom surface of the case fitting portion 2 and reaches the base portion 3.
This can be prevented from occurring.

Although the above-mentioned embodiment is constructed as described above, when implementing the present invention, specific modifications such as the use outlet, the use chamber, the rotating shaft, the water-shielding ribs, etc. shall be made unless it goes against the gist of the invention. Of course, the structure, shape, position, material, etc. can be configured and implemented in various ways without being restricted to the one embodiment described above.

[Effect of idea]

According to the present invention, which has the configuration described in the above-mentioned utility model registration claim, a part of the juice flowing out from the juice outlet is directed to the rotating shaft side of the juicer without increasing the height of the draining rib. This has the practical effect of preventing water from flowing.
