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. It was necessary to turn the filter to the position where the horizontal grooves engaged. For this reason, if you forget to turn it, the engagement will not take place and the filter will pop out. In order to solve this problem, it has been considered to form a groove with an inclined passage, but there is a problem in that simply forming a groove does not allow easy and smooth removal of the filter.

Purpose of the Invention The present invention prevents the filter from jumping out by simply inserting a comb-shaped filter into the separation cage, by reliably engaging the protrusion of the separation cage with the groove of the filter regardless of the insertion position of the filter. When removing the filter, its position is regulated so that it can be done easily and smoothly.

Composition of the Invention The present invention comprises a main body that includes a built-in electric motor, a container placed on the main body, a container lid that covers the upper opening of the container, a cylindrical separating basket driven by the electric motor, and a separating basket that is also located inside the container. a comb-shaped filter that is removably fitted, the separating basket has a plurality of protrusions formed on its inner upper part, and the filter has an inclined wall that spans over the plurality of slits and engages with the protrusions. A plurality of grooves are formed in the inclined wall, and a regulating part is formed in the middle of the inclined wall to which a protrusion engages and regulates the removal position of the filter when the filter is removed by rotating the filter in the direction of rotation of the separating basket. By simply inserting the filter into the separating cage, the filter is reliably engaged by the action of the sloping wall, and when the filter is removed, the removal position is regulated by the regulating portion of the slanted wall.

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 connected to an upper body 4 and a lower body 5 via a cushioning rubber 3.
It is attached by screw 6 to. 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. Further, a first pulley 9 is fixed in the middle of the rotating shaft 7 by a pin 10. A pulley shaft 11 is fixed to the chassis 2, and a second pulley 12 and a third pulley 13 having two diameters, large and small, are mounted on this shaft 11.
and are attached so that they rotate together.

14 is a cylindrical connector arranged concentrically with the rotating shaft 7 and rotates at a low speed with the connector 8 housed inside, has a fourth pulley 15 at the bottom, and has a cylindrical separating cage 16 on the lower surface of 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 around 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.

Several protrusions 24 are provided on the upper part of the inner surface of the separating basket 16. 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 approximately triangular combs between the slits. tooth 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 passageway 29 is provided at the top of the
A groove 30 is formed. The inclined passageway 29 is provided with inclined walls 29a and 29b for guiding the protrusion 24, and in the middle of the inclined walls 29a and 29b, there is a wall extending from the extension line of the lower end surface 31 of the groove 30 on the extension line of the comb teeth 27b. A vertical restriction portion 29c is formed at the top. Even if the protrusion 24 passes through either the space 28a or 28b, it enters the groove 30 portion while being guided by the inclined wall 29a or the inclined walls 29b, 29a. The lower surface of the groove 30 consists of the lower end surface 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 inserted into the protrusion 24 of the separation cage 16.
When the protrusion 24 is inserted into the slit 26a or the space 28a or 28b of the slit 26b, the protrusion 24 comes into contact with the slit 29a or 29b, and is guided by the inclined wall thereof and moves to the groove 30,
It will fit automatically.

At the position where the lower surface of the filter 25 is in contact with the bottom surface of the separation basket 16, the protrusion 24 and the lower end surface 31 of the groove 30 are always connected.
Alternatively, it comes into contact with the inclined portion 32 and is prevented from coming off.

Conversely, when removing the filter 25, when the filter 25 is rotated in the direction of rotation of the separating basket 16, the protrusion 24 will hit the regulating portion 29c and be pulled upward, allowing the protrusion 24 to pass through the space 28a and easily without resistance. It can be taken out. That is, the regulating portion 29c regulates the removal position of the filter 25.

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 33 juices contained in the container are stored in the juice receiver 38 through a hole 37 provided in the container 33. Note that 39 is a rubber band fixed to the lower body 5.

Next, when the juice is squeezed 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, after turning the filter 25 in the same direction as the rotation direction of the separation basket 16, pull it out.
Discard the squeezed lees stuck inside the filter 25. 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, in the present invention, no matter which position the filter is inserted into the separating basket, the protrusion on the upper part of the separating basket and the groove of the filter automatically and reliably fit together due to the action of the inclined wall. Prevents the filter from popping out.
Furthermore, when taking out the filter, the protrusion is regulated by the regulating part and can be taken out upwards, so it can be easily and smoothly operated.
