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.

First claim

What is claimed is:

1. 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 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 comprising:
a crushing portion formed on a top end of the screw, the crushing portion having a crushing blade formed thereon; and
a crushing processing portion formed in the lid such that a material guide surface and a crushing processing surface of the crushing processing portion continue from the input port,
wherein the input port is parallel to and is laterally offset from a central axis of the screw and has a width larger than the shortest distance from the central axis of the screw to an inner circumferential surface of a top end of the sieve, and
wherein the crushing blade crushes the material in advance within the crushing processing portion of the lid.

2. The juice extraction module according to claim 1 , wherein the crushing processing portion is formed in a bottom portion of the lid and is concave to accommodate the crushing portion of the screw.

3. The juice extraction module according to claim 1 , wherein the crushing blade is formed so that the material input through the input port is crushed while a lateral side of the material is pushed outwards, and the crushing processing portion of the lid holds the material pushed outwards by the crushing blade, whereby the material is crushed between the crushing blade and the crushing processing portion.

4. The juice extraction module according to claim 1 , wherein the crushing processing surface is formed to be increasing close to the crushing blade in a direction in which the crushing blade rotates away from the input port during operation.

5. The juice extraction module according to claim 1 , wherein the material guide surface is formed to be inclined toward a central axis of the crushing portion of the screw, whereby the material guide surface guides the material so that a lateral side of the material begins to be crushed by the crushing blade.

6. The juice extraction module according to claim 5 , wherein a bottom end of the material guide surface conforms to an inner surface of the sieve.

7. The juice extraction module according to claim 1 , wherein the crushing processing surface is formed to be increasing close to the crushing blade in a direction in which the crushing blade rotates away from the input port during operation, and wherein the material guide surface is formed to be inclined toward a central axis of the crushing portion of the screw to cause a lateral side of the material to begin to be crushed by the crushing blade.

8. The juice extraction module according to claim 1 , wherein the crushing portion of the screw extends above a top end of the sieve and is accommodated within the crushing processing portion of the lid.

9. The juice extraction module according to claim 1 , wherein the crushing processing surface is formed with at least one milling blade.

10. A juice extraction module for a juicer, comprising:
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,
wherein the input port is parallel to and is laterally offset from a central axis of the screw and has a width larger than the shortest distance from the central axis of the screw to an inner circumferential surface of a top end of the sieve,
wherein a crushing portion is formed on a top end of the screw, the crushing portion having a crushing blade formed thereon, and
wherein the lid is formed with a crushing processing portion having a material guide surface and a crushing processing surface that extend from the input port to guide the material from the input port to the sieve.

11. The juice extraction module according to claim 10 , wherein the crushing blade and the crushing processing portion are formed so that a distance between the crushing blade and an inner surface of the crushing processing portion of the lid reduces in a rotational direction in which the crushing blade rotates during operation.

12. The juice extraction module according to claim 10 , wherein the crushing processing surface is formed with at least one milling blade.

13. A juice extraction module for a juicer comprising:
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 central axis and extract juice from a material, the screw including a crushing portion formed at a top end thereof which includes a crushing blade formed thereon; and
a lid coupled to a top end of the container, the lid including an input port through which the material is input and a crushing processing portion having a material guide surface and a crushing processing surface that extend from the input port to guide the material from the input port to the sieve,
wherein the input port is parallel to and is laterally offset from the central axis of the screw and has a width larger than the shortest distance from the central axis of the screw to an inner circumferential surface of a top end of the sieve.

14. The juice extraction module according to claim 13 , wherein the crushing processing surface is formed to be increasingly close to the crushing blade of the screw in a rotational direction in which the crushing blade rotates about the central axis during operation.

15. The juice extraction module according to claim 13 , wherein the material guide surface is formed to be inclined toward the central axis, whereby the material guide surface guides the material so that a lateral side of the material begins to be crushed by the crushing blade during operation.
