## Abstract

A juice extraction module for a juicer is provided, which includes a container formed with a juice discharge port, a sieve positioned inside of the container, a screw positioned inside of the sieve to extract juice from a material, and a lid coupled to a top end of the container and formed with a input port through which the material is input. The juice extraction module includes a crushing portion formed on a top end of the screw to be narrowed upward, the crushing portion having a crushing blade formed thereon; and a crushing processing portion connected to the input port and formed in a bottom of the lid to be concave for accommodating the crushing portion.

## Claims

### Claim 1

A juice extraction module for a juicer, the juice extraction module including:
a container comprising a juice discharge port;
a sieve positioned inside of the container;
a screw to extract juice from a material, the screw being rotatable about a rotational axis and having top and bottom portions vertically arranged along the rotational axis, the bottom portion of the screw being accommodated within the sieve and the top portion of the screw extending out of the sieve;
a lid coupled to a top end of the container, the lid having:
a top portion that includes an input port through which said material is input into the juice extraction module, and
a bottom portion that receives said material from the input port,
wherein the top portion of the screw has a spiral blade formed thereon and extends above a top end of the sieve to narrow toward a top end of the screw,
wherein the bottom portion of the lid includes a screw accommodating portion configured to accommodate the top portion of the screw,
wherein a first material processing zone in which said material is subjected to crushing, in use, is defined between the top portion of the screw and an interior surface of the lid above the top end of the sieve,
wherein a second material processing zone in which said material is subjected to juicing, in use, is defined between the bottom portion of the screw and the sieve,
wherein the input port is proportioned to accommodate material of up to a first diameter in size, the first diameter being greater than a shortest distance between the rotational axis of the screw and an inner circumferential edge at an entrance of the top end of the sieve, and
wherein the input port is located above the entrance of the top end of the sieve and, when viewing the juice extraction module from a top plan view, partially overlaps with the entrance of the top end of the sieve such that a portion of the input port is outside a projected boundary of the entrance of the top end of the sieve.

### Claim 2 (depends on 1)

The juice extraction module according to claim 1, wherein the first material processing zone reduces in size between its upstream and downstream ends.

### Claim 3 (depends on 1)

The juice extraction module according to claim 1, wherein the screw is of unitary one-piece construction.

### Claim 4

A juice extraction module for a juicer, which includes a container formed with a juice discharge port, a sieve positioned inside of the container, a screw positioned inside of the sieve to rotate about a rotational axis and extract juice from a material, and a lid coupled to a top end of the container and formed with an input port through which the material is input, the juice extraction module comprising:
a top portion of the screw defining a crushing portion, the crushing portion comprising a crushing blade formed thereon; and
a crushing processing portion connected to the input port and defined in a bottom portion of the lid, the crushing processing portion accommodating the crushing portion of the screw, an inner surface of the crushing processing portion including a crushing processing surface and a material guide surface,
wherein the input port is an opening formed in a top portion of the lid,
wherein the material guide surface continues from the input port and is inclined toward the rotational axis, whereby the material guide surface guides the material so that the material begins to be crushed by the crushing blade, and wherein the crushing blade crushes the material within the crushing processing portion formed in the bottom of the lid, in advance of the material reaching the sieve, and
wherein the input port is located above an entrance of a top end of the sieve and, when viewing the juice extraction module from a top plan view, partially overlaps with the entrance of the top end of the sieve such that a portion of the input port is outside a projected boundary of the entrance of the top end of the sieve.

### Claim 5 (depends on 4)

The juice extraction module according to claim 4, wherein the screw is of unitary one-piece construction.

### Claim 6

A juice extraction module for a juicer, comprising:
a container comprising a juice discharge port;
a sieve positioned inside of the container;
a screw positioned inside of the sieve to rotate about a rotational axis and extract juice from a material, a top portion of the screw defining a crushing portion which includes a crushing blade formed thereon; and
a lid coupled to a top end of the container and comprising an input port through which the material is input, a bottom portion of the lid comprising a crushing processing portion connected to the input port, the crushing processing portion accommodating the crushing portion of the screw and having an inner surface that includes a crushing processing surface,
wherein the input port is an opening formed in the lid,
wherein the crushing blade crushes the material within the crushing processing portion formed in the bottom of the lid, in advance of the material reaching the sieve, and
wherein the input port is located above an entrance of a top end of the sieve and, when viewing the juice extraction module from a top plan view, partially overlaps with the entrance of the top end of the sieve such that a portion of the input port is outside a projected boundary of the entrance of the top end of the sieve.

### Claim 7 (depends on 6)

The juice extraction module according to claim 6, wherein the screw is of unitary one-piece construction.
