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

The invention claimed is:

1. A structure of crushing a material in advance for use in a juice extraction module including a container having a juice extraction space, a screw for extracting juice from the material in the container and a lid having an input port through which the material is input into the container, characterized in that the structure comprises:
a crushing portion formed on a top end of the screw to be narrowed upward, the crushing portion having a crushing blade formed thereon,
wherein the lid has a crushing processing portion formed in a bottom of the lid,
wherein the crushing processing portion formed in the bottom of the lid is configured to accommodate the crushing portion formed on the top end of the screw,
wherein the crushing processing portion formed in the bottom of the lid is connected with the input port, and cooperates with the crushing portion formed on the top end of the screw to crush the material input through the input port in a space between the crushing blade of the crushing portion formed on the top end of the screw and an inner surface of the crushing processing portion formed in the bottom of the lid,
wherein the input port of the lid is offset toward one side with respect to a central axis of the screw,
wherein a width of the input port is greater than a maximum radius from the central axis of the screw to the crushing blade of the crushing portion of the screw, and
wherein the crushing blade of the crushing portion of the screw is configured to crush the material while pushing a lateral side of the material outward, and the crushing processing portion of the lid is provided with an inner surface to hold the material pushed outward by the crushing blade, whereby the material is crushed between the crushing blade of the crushing portion of the screw and the inner surface of the crushing processing portion of the lid.

2. The structure of claim 1 , wherein a bottom width of the input port is larger than a diameter of the screw.

3. The structure of claim 2 , wherein the crushing processing portion comprises a material guide surface for assisting guidance of the material from the input port to the crushing portion.

4. The structure of claim 1 , wherein the crushing blade and the crushing processing portion are formed so that a space between the crushing blade and an inner surface of the crushing processing portion is gradually narrowed.

5. The structure of claim 1 , wherein an inner surface of the crushing processing portion comprises a crushing processing surface formed to be increasingly close to the crushing blade in a direction in which the crushing blade runs from the input port.

6. The structure of claim 1 , wherein the crushing processing portion comprises a material guide surface continuing from the input port and formed to be inclined toward a central axis of the crushing portion.

7. A structure of crushing a material in advance for use in a juice extraction module including a container having a juice extraction space, a sieve positioned inside of the container, a screw for extracting juice from the material in the container and a lid having an input port through which the material is input into the container, characterized in that the structure comprises:
a crushing portion formed on a top end of the screw, the crushing portion having a crushing blade formed thereon,
wherein the lid has a crushing processing portion formed in a bottom of the lid,
wherein the crushing processing portion formed in the bottom of the lid is configured to accommodate the crushing portion formed on the top end of the screw,
wherein the crushing processing portion formed in the bottom of the lid is connected with the input port, and cooperates with the crushing portion formed on the top end of the screw to crush the material input through the input port in a space between the crushing blade of the crushing portion on the top end of the screw and an inner surface of the crushing processing portion formed in the bottom of the lid,
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,
wherein the input port of the lid is offset toward one side with respect to a central axis of the screw,
wherein a width of the input port is greater than a maximum radius from the central axis of the screw to the crushing blade of the crushing portion of the screw, and
wherein the crushing blade of the crushing portion of the screw is configured to crush the material while pushing a lateral side of the material outward, and the crushing processing portion of the lid is provided with an inner surface to hold the material pushed outward by the crushing blade, whereby the material is crushed between the crushing blade of the crushing portion of the screw and the inner surface of the crushing processing portion of the lid.

8. A juice extraction module for a juicer, the juice extraction module including:
a container formed with 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
a lid coupled to a top end of the container, the lid having an input port through which said material is input into the juice extraction module in a direction parallel to the rotational axis, a lower end of the input port being offset from a top portion of the screw in a direction perpendicular to the rotational axis,
wherein the top portion of the screw has a spiral blade formed thereon and narrows toward a top end of the screw,
wherein a first material processing portion extends from the lower end of the input port to accommodate the top portion of the screw, the first material processing portion comprising a first material processing surface and a material guide surface,
wherein a first material processing zone for subjecting said material to a first material processing action is defined between the first material processing surface and the top portion of the screw,
wherein the material guide surface extends from the lower end of the input port and is inclined toward the rotational axis to guide said material from the lower end of the input port toward the top portion of the screw, and
wherein a second material processing zone for subjecting said material to a second material processing action is defined between a bottom portion of the screw and the sieve.

9. The juice extraction module of claim 8 , wherein the first processing action comprises rotation of the screw causing the blade on the top portion of the screw to press the material against the first processing surface and thereby crush the material before it passes to the second material processing zone, and wherein the second material processing action comprises rotation of the screw causing the bottom portion of the screw to press the material against the sieve and thereby extract juice from the material.

10. The juice extraction module of claim 8 , wherein the lower end of the input port is offset from the rotational axis of the screw, in the direction perpendicular to the rotational axis of the screw, within a semicircle region of a circle having a diameter corresponding to a diameter of the first material processing portion, the circle being centered on the rotational axis of the screw.

11. The juice extraction module of claim 8 , wherein a distance between the first material processing surface and the blade of the screw reduces in a rotational direction in which the bl
