Patent ID: 8770100

Claim:
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 central 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 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 on the top end of the screw, an inner surface of the crushing processing portion including a crushing processing surface and a material guide surface, 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 such that a first distance between the crushing processing surface and an outer edge of the crushing blade at a first location rotationally adjacent the input port is greater than a second distance between the crushing processing surface and the outer edge of the crushing blade at a second location rotationally adjacent the first location and such that the second distance between the crushing processing surface and the outer edge of the crushing blade at the second location is greater than a third distance between the crushing processing surface and the outer edge of the crushing blade at a third location rotationally adjacent the second location, wherein the material guide surface continues from the input port and 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, and wherein the crushing blade crushes the material in advance within the crushing processing portion formed in the bottom of the lid.
