Multifunctional juicer with conversion module

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a multi-function juicer whose speed can be controlled; more particularly, to a function that can be simultaneously rotated by a high speed to provide a stirrer and by a low speed to provide a juicer.

A conventional juicer accommodates fruit or vegetables in its outer casing, and a screw is rotatably mounted in the outer casing, and the screw is rotated by a driving unit located at the bottom of the outer casing, thereby grinding the fruits and vegetables. Next, the user takes out the ground fruits and vegetables and uses them.

Since the contents are finely ground by a screw at a high speed, the conventional juicer has the advantage that it can be carried out and finished in a short time. However, since the screw system grinds fruits and vegetables at high speed, it may cause the unique taste and nutrients of the fruits and vegetables to be destroyed. That is to say, the limitation of the conventional juicer is that the user cannot completely enjoy the unique original taste of the fresh fruits and vegetables, and the nutrients required for maintaining the health of the human body may also be lost.

Recently, the juice extractor 5, which can reduce the rotational speed, has received more and more attention because it can solve the above problems, as shown in Fig. 1. The juicer 5 utilizes a method of extracting the juice into the juice by the low speed rotating screw 30. This approach requires considerable force to squeeze the juice into juice at a reduced screw speed. Therefore, the juicer 5 presses the fruits and vegetables by the gears formed in the rotating body.

However, inevitably, the efficiency of this technique is not high, mainly because the juicer 5 must maintain a certain number of revolutions regardless of the contents of the juicer. In addition, when the grinding screw under low speed operation must handle the contents with a large load, For example: solid or high density vegetables, such as: carrots, at this point, the drive unit may be blocked and stopped. In this case, it is extremely inconvenient for the user to remove the clogging in the drive unit and restart the juicer.

Accordingly, the multi-function juicer of the present invention is provided with a detachable variable module to provide a blender function to grind the contents, and a juicer function to press the contents. The function of the juicer can be adjusted depending on the type of content in the juicer or the needs of the user.
