Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a juicer, and more particularly to the attachment and detachment of a separation cage stand to which a separation cage and cutter of a juicer are attached, and a rotary stand fixed to a motor shaft.

Conventionally, this type of juicer consists of a pin provided inside the rotary table that pops out due to centrifugal force, and an annular groove formed on the inner surface of the separation car stand with which this pin engages, or a separate piece from the rotary table. Some systems have a clutch ring that engages with a protrusion provided on the inner surface of the separation car stand using a spring provided between the rotary table and the clutch ring.

However, in the former case, an annular protrusion must be formed on the inner surface of the bottomed ring-shaped separation car stand due to the annular groove, and generally, in order to integrally mold it with plastic, it is necessary to Due to construction difficulties, the separation car stand is molded from aluminum die-casting, and the annular recess is formed by cutting.
Post-processing was required, which was time-consuming.

In addition, the latter has a problem in that it requires a large number of parts, such as a rotary table, clutch ring, and spring, and is complicated to assemble.

The present invention addresses these shortcomings and aims to simplify the structure of the separating car stand to which the separating car and cutter are attached, and the attachment and detachment of the rotary stand.

The present invention is characterized in that the separation car stand and the rotary stand in the juicer are engaged from above and below, the separation car stand is made of an elastic body, and the separation car stand has a plurality of pawls provided with burrs. The rotating table is provided with a plurality of recesses that engage with the pawls.

An embodiment of the present invention will be described below based on the drawings.

In the figure, a motor 1 is housed in a main body case 2, with a motor shaft 3 protruding from the center thereof, and a rotary table 4 is fixed to the motor shaft 3 by screws.

The inner case 5 is detachably attached to the main case 2 together with the lid 13 by a clamp device (not shown), and the inner case 5 has a lees receiving part 6, a youth chamber 7, and a youth outlet 8A. be.

The separation basket 9 is composed of a filter 10 in the shape of an inverted cone and having a plurality of small holes for separating the waste from the material and allowing the waste to pass through, a vertical wall 9A, and a cutter 11 for cutting and crushing the material. These are integrally fixed to the plastic separating car stand 12.

The lid 13 has a cutting chamber 14 for the cutter 11 consisting of a cylindrical portion 14A, a conical portion 14B, and a cylindrical portion 14C from the top, and inside this cutting chamber 14,
It has a hole 14D through which material can be input.

Note that the legs 18 are fixed to the bottom plate 19, and the distiller scoop 20 is provided in a part of the main case 2 and includes a foam strainer 21.

Further, the separating car stand 12 has a pawl portion 30 having a burr portion 31, and the rotary table 4 has a pawl portion 30 having a burr portion 31.
There are a recessed portion 33 and a sloped portion 39 that engage with. Reference numeral 42 denotes a fan, which increases the cooling effect against the temperature rise of the electric motor 1 by rotating the rotary table 4.

Its function will be explained in the above configuration. When the separation car stand 12 and the turntable 4 are attached, the boss portion 40 provided at the center of the separation car stand 12 is engaged with the insert part 41 of the turntable 4, and thereby the separation car stand 12 and the turntable 4 are attached. centering becomes possible.

In addition, the outer diameter of the burr 31 provided on the pawl 30 is equal to the outer diameter of the recess upper wall surface 34 of the recess 33 provided on the rotary table 4.
Since the pawl portion 30 is formed larger, when the pawl portion 30 is on the concave portion 33, the pawl bottom portion 32 that comes into contact with the top wall surface of the concave portion bends inward because the pawl portion 30 is an elastic body, and the slanted portion 36 becomes a guide. As a result, the claw portion 30 engages with the recess 33.

When the pawl 30 and the recess 33 are in any position, the pawl bottom 32 is guided by contact with the slope 39 provided between the recesses and moves along the slope,
The pawl portion 30 is positioned above the recess 33, and the burr slope portion 36 serves as a guide, so that the pawl portion 30 is placed over the recess 33.
engage with.

When the burr portion 31 engages up to the lower wall surface 35 of the recess, the pawl portion 30 returns due to its elastic force, and the engagement is completed.

The rotational force is applied to the pawl side 37 by the concave side 38.
is transmitted to rotate the separation cage stand 12, and the function as a juicer is emitted. In addition, the burr portion 31 bends over the lower wall surface 35 of the recess in response to an upward force, and during rotation, the pawl portion 30 bends in the outer circumferential direction due to centrifugal force, thus acting as an upward stopper.
The pawl portion 30 does not come out of the recess 33 during rotation.

At the time of removal, by applying an upward force to the separating car stand 12, the pawl portion 30 is bent inward, the burr portion 31 is disengaged from the lower wall surface 35 of the recess, and the car can be removed.

According to the present invention, the separation car stand and the rotary stand can be attached and detached from above and below by engaging the claws and the recesses, which simplifies the structure, reduces the number of parts involved, and improves ease of handling. It is something that can be done.
