ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a juicer/juice extractor, and more particularly to a dual function juicer/juice extractor that can be used as either a juicer for extracting juice from fruit with peel or a juice extractor for extracting juice from fruit without peel, rootstock, or vegetable.
2. Description of the Related Art
A juice extractor is used to extract juice from fruit without peel (such as apples, pineapples, kiwis, etc.), rootstock, or vegetable. However, the juice extractor cannot be used to extract juice from fruit with peel (i.e., citrus) such as oranges, grapefruits, lemons, etc., as the juice extracted will taste bitter. A juicer is generally used to extract juice from citrus, but it cannot be used to extract juice from fruit without peel, rootstock, or vegetable. Thus, the users must buy both a juice extractor and a juicer, which is uneconomic.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a juicer/juice extractor that can be used as either a juicer for extracting juice from fruit with peel or a juice extractor for extracting juice from fruit without peel, rootstock, or vegetable, thereby saving the cost.
A juicer/extractor in accordance with the present invention comprises:
a base;
a drip cup supported by the base;
a vertical rod having a lower end located above the drip cup;
means for moving the vertical rod along a vertical direction;
a column extending upward from the base and including a portion for supporting the vertical rod and allowing vertical movement of the vertical rod;
a juicing device for extracting juice from citrus; and
a pressing device for extracting juice from fruit without peel, rootstock, or vegetable;
one of the juicing device and the pressing device being releasably mounted between the lower end of the vertical rod and the drip cup.
The juicing device comprises a reamer mounted above the drip cup and a pressure cup having a lower end above the reamer and an upper end releasably engaged with the lower end of the vertical rod. The lower end of the vertical rod comprises an outer threading and the upper end of the pressure cup includes an inner threading for engaging with the outer threading of the lower end of the vertical rod.
The pressing device comprises a dripping plate mounted on top of the drip cup and a pressing plate having a lower side above the dripping plate and an upper side releasably engaged with the lower end of the vertical rod. The lower end of the vertical rod comprises an outer threading. The pressing plate comprises an engaging stem extending from the upper side thereof The engaging stem includes an end having an inner threading for engaging with the outer threading of the lower end of the vertical rod. The lower side of the pressing plate comprises a plurality of annular ribs formed thereon. The dripping plate comprises a plurality of rows of recessed sections each having a plurality of dripping holes communicated with the drip cup A strainer cone surrounds at least a lower portion of the engaging stem to thereby prevent splashing of juice.
Other objects, advantages, and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
