Abstract

A food processor includes a lower bowl, a mediate bowl disengagably mounted to the lower bowl, a disk mounted to the mediate bowl, a cap mounted to the disk and a shaft with a spring mounted thereto extending through the cap with a first end thereof and extending in the mediate bowl with a second end thereof so as to connect a fixing plate. The mediate bowl has a slit defined in a bottom thereof and a scrapping blade fixedly disposed to the bottom adjacent the slit. A crank member is securely connected to and rotates the other end of the shaft extending from the cap so as to rotate the shaft to scrap a large ice cube securely pressed between the bottom and the fixing plate by the scrapping blade. The shaft can alternatively rotate a blade device rotatably mounted to the lower bowl when the mediate bowl is removed.

Claims

1. A food processor comprising:

a lower bowl having a first bottom and a first peripheral wall extending from said bottom, a protrusion extending from an inner side of said first bottom for a blade means rotatably mounted thereto;

a mediate bowl having a second bottom and a second peripheral wall extending from said second bottom, a slit defined in said second bottom and a scrapping blade fixedly and inclinedly disposed to said second bottom wherein a sharp edge of said scrapping blade extends above an inner side of said second bottom and is located adjacent to said slit, an outer peripheral wall disposed around said second peripheral wall with a plurality of connecting plates connecting between said second peripheral wall and said outer peripheral wall which is mounted to said first peripheral wall;

a disk disengagably mounted to said mediate bowl and having a central hole defined therethrough;

a cap mounted to said disk and having a first hole defined therethrough;

a first shaft having a polygonal cross section and having a first end extending through said first hole of said cap and a second end extending through said central hole of said disk, a fixing plate disengagably connected to said second end of said first shaft, a flange extending radially from said first shaft so that a spring is mounted to said first shaft and biasedly disposed between said flange and an inner flange extending inwardly and radially from an inner periphery defining said first hole, and

a crank member having a first end with a first polygonal recess defined therein so as to securely mount to said first end of said first shaft and rotate said shaft.

2. The food processor as claimed in claim 1 wherein said blade means has a second polygonal recess defined in a top thereof so as to receive said second end of said first shaft.

3. The food processor as claimed in claim 1 wherein a handle is disengagably attached to an outer periphery said first peripheral wall.

4. The food processor as claimed in claim 3 wherein said first peripheral wall has an inverted U-shaped bracket disposed to said outer periphery thereof, said bracket having an open bottom end and a space defined between said first peripheral wall and said bracket, at least one tapered rib extending from said outer periphery of said first peripheral wall, said handle having at least one T-shaped member extending laterally therefrom so that said T-shaped member is inserted into said space and being securely positioned between said tapered rib and said bracket.

5. The food processor as claimed in claim 1 wherein each of said connecting plates extends perpendicularly to said outer peripheral wall and said second peripheral wall, a plurality of holes defined in each of said connecting plates.

6. The food processor as claimed in claim 1 wherein a first gear is rotatably disposed on said disk and has a polygonal hole defined therethrough which communicates with said central hole so that said first shaft extends through said polygonal hole, said cap having a second hole defined therein, a gear set rotatably on said disk and having a second gear and a third gear which is engaged with said first gear, a second shaft having a first end extending through said second hole and a second end with a fourth gear disposed thereto which is engaged with said second gear.

7. The food processor as claimed in claim 1 wherein said lower bowl has a pouring outlet defined in said first peripheral wall.
