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 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 of crushing a material in advance 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 to be concave and gradually narrowed upward from a face coupled with the container in order to accommodate the crushing portion, and
wherein the crushing processing portion is connected with the input port, and cooperates with the crushing portion to crush the material input through the input port.

2. The structure of crushing a material in advance of claim 1 , wherein the input port is offset toward one side with respect to a central axis of the screw.

3. The structure of crushing a material in advance of claim 2 , wherein a bottom width of the input port is larger than a diameter of the screw.

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

5. The structure of crushing a material in advance of claim 2 , 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.

6. The structure of crushing a material in advance 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.

7. The structure of crushing a material in advance 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.

8. 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 of crushing a material in advance 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 to be concave upward from a face coupled with the container in order to accommodate the crushing portion,
wherein the crushing processing portion is connected with the input port, and cooperates with the crushing portion to crush the material input through the input port, and
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.
