Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a juicer having a rotating cylindrical separation cage and a comb-shaped filter provided within the separation cage.

Conventional structure and its problems In the conventional extractor of this type, the protrusion in the separating cage engages the comb-shaped filter only in the horizontal groove of the filter, so the filter is inserted until it hits the bottom of the separating cage, and then the protrusion is inserted. Since it was necessary to turn the filter to a position where the lateral grooves and the horizontal grooves were engaged, there was a problem in that if the filter was forgotten to turn, the engagement would not take place and the filter would pop out.

Purpose of the Invention The present invention prevents the filter from flying out by inserting a comb-shaped filter into the separation cage, thereby automatically and reliably engaging the protrusion of the separation cage with the groove of the filter.

Structure of the Invention By forming a plurality of grooves each having an inclined wall that engages with a plurality of protrusions of a separating basket in the upper part of the slit formed in the comb-shaped filter of the present invention, and inserting the filter into the separating basket. , the groove of the filter and the protrusion of the separating basket are automatically engaged.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In the figure, reference numeral 1 denotes an electric motor, which is fixed to a chassis 2 and attached to an upper body 4 and a lower body 5 with screws 6 via a cushioning rubber 3. A connector 8 that is directly connected to the tip of the rotating shaft 7 of the electric motor 1 and rotates at high speed is attached. In addition, a first pulley 9 is located in the middle of the rotating shaft 7.
is fixed by a pin 10. Chassis 2
A pulley shaft 11 is fixed to the shaft 11, and a second pulley 12 and a third pulley having two diameters, large and small, are mounted on this shaft 11.
The pulley 13 is attached to rotate together with the pulley 13.

Reference numeral 14 denotes a cylindrical connector that rotates at low speed and is arranged concentrically with the rotating shaft 7 and houses the connector 8 inside.It has a fourth pulley 15 at the lower part, and the lower surface of the cylindrical separation basket 16 at the upper part. Fitting part 1 provided in
It has a connector part 18 that fits into the connector part 7. 19 is a cap attached to the low speed connector 14.

The connector 14 is decelerated by one step by a belt 20 placed between pulleys 9 and 12, and further decelerated by two steps by a belt 21 placed by pulleys 13 and 15. The rotational speed of the electric motor 1 is reduced to a fraction by the speed reduction mechanism and transmitted to the connector 14, and this reduced rotation is transmitted to the separation cage 16 via the fitting portion 17 that is removably fitted thereto. Reportedly.

Reference numeral 22 denotes a juicer cutter, which is integrally attached to the separation cage 16 and the fitting portion 17 with screws 23. There are several protrusions 24 on the upper inner surface of the separation basket 16.
has been established. Reference numeral 25 denotes a cylindrical, comb-shaped filter made of an elastic material such as resin that fits on the inner surface of the separation basket 16, and has a large number of slits 26 in the vertical direction, leaving the upper part on the side wall, and triangular comb teeth between the slits. 27
is provided. The slit 26 is recessed inward from the outer surface of the filter 25.
6a is the apex, and two comb teeth 27 are in contact with it.
A substantially triangular space 28a is formed between a and 27b. Similarly, it has a space 28b which has the slit 26b as its apex and is sandwiched between the comb teeth 27b and 27c. In this way, a large number of spaces 28a, 28b are provided. Two slits 26a and 26b
An inclined passage 29 for guiding the protrusion 24 is provided at the upper part of the protrusion 24, and the protrusion 24 enters into a groove 30 connected to the inclined passage 29. The lower end surface of the groove 30 consists of a portion 31 perpendicular to the slit 26 and an upwardly inclined portion 32.

When fitting the filter 25 into the separation cage 16, the filter 25 is fitted into the protrusion 24 of the separation cage 16.
When the space 28a or 28b of the slit 26a or 26b is inserted, the protrusion 24
comes into contact with the wall of the inclined passage 29, and is guided by the inclined wall from there to move into the groove 30 portion and is automatically accommodated.

At the position where the lower surface of the filter 25 contacts the bottom surface of the separating basket 16, the protrusion 24 and the perpendicular portion 31 or the inclined portion 32 of the groove 30 always come into contact to prevent the filter from coming off.

Conversely, when removing the filter 25, rotate the filter 25 in the direction of rotation of the separation basket 16 and remove the protrusion 24.
is moved to the position of space 28a or 29a and pulled out as it is.

33 is a container containing the separation basket 16, and is installed on the upper body 4. A container lid 34 covers the opening of the container 33. 35 is an input port formed in the container lid 34, and 36 is a push rod.

Now, using the push rod 36 from the input port 35, cut the juice materials such as fruits and vegetables into the juicer cutter 2.
2, the material is finely pulverized and sent to the filter 25. A filter 25 separates the material into a solid content and a youth content.

The solid content remains as residue in the filter 25,
The juice portion is ejected from the separating basket 16 by centrifugal force and enters the container 33. The juice that has entered the container 33 is stored in a juice receiver 38 through a hole 37 provided in the container 33. Note that 39 is a reed rubber fixed to the lower body 5.

Next, when the juice is finished squeezing and the squeezed lees is to be processed, the container lid 34 is removed from the container 33, and the separation basket 1 is removed.
Take out 6. Then, remove the filter 25 from the separating basket 1.
After turning the filter 25 in the same direction as the rotation direction of the filter 25, the filter 25 is pulled out and the squeezed dregs adhering to the inside of the filter 25 are discarded. Note that the separation basket 16 has no holes, and the filter 25 also has no holes but has slits 26, so that they have the advantage of being easy to process and easy to wash.

The connector 8 is used to transmit power to the mixer cutter by removing the juicer attachment and attaching the mixer attachment.

Effects of the Invention As described above, the present invention allows the protrusion on the upper part of the separation basket and the groove of the filter to automatically and reliably fit together due to the action of the inclined wall, no matter which position the comb-shaped filter is inserted into the separation basket. This prevents the filter from popping out, eliminates abnormal noise, vibration, etc., and allows the separating cage and filter to be easily fitted. Therefore, handling of the juicer is extremely easy, and it is safer and more convenient to use.
