A juice extractor appliance, and a cutter disc therefor, the cutter disc being eccentrically mountable with respect to a feed tube for feeding food articles and being formed, on its surface facing feed tube, with a first group of blades in a circular region centrally of the cutter disc, and with a second group of blades in an outer peripheral region of the cutter disc around the central region. The first group of blades consist of two blades located on opposite sides of the central circular region and diametrically aligned with each other and with the center of the central circular region. The second group of blades consist of a plurality of lines of blades in the outer peripheral region extending tangentially to the center circular region.

1. A juice extractor appliance for extracting juice from food articles, comprising:a housing having an inlet feed tube for feeding the food articles into the appliance, and an outlet for outletting the juice extracted therefrom; a cutter disc rotatably mounted within said housing eccentrically with respect to said inlet feed tube for cutting the food articles fed into the housing into a pulp saturated with juice; a separator device within said housing for separating the juice from the pulp, which juice is outletted through said housing outlet; and a drive within said housing for driving said cutter disc; said cutter disc being formed on its surface facing the feed tube with a first group of blades in a circular region centrally of the cutter disc, and with a second group of blades in an outer peripheral region of the cutter disc around said central region; said first group of blades consisting of two blades located on opposite sides of said central circular region and diametrically aligned with each other and with the center of said central circular region; one of said blades extending diametrically across one side of said central circular region and terminating substantially at the center thereof, the other of said blades extending diametrically across the opposite side of said central circular region and terminating short of the center thereof; said second group of blades consisting of a plurality of lines of blades in said outer peripheral region radiating from said center circular region; said central region of the cutter disc on which said first group of blades is formed being separate from and rotatable with respect to said outer peripheral region on which said second group of blades is formed. 2. The appliance according to claim 1, wherein the blades of said second group extend tangentially with respect to said center circular region.3. The appliance according to claim 1, wherein the blades of said second group radiate from approximately the mid-point of radial lines through said central circular region.4. The appliance according to claim 1, wherein said appliance further includes a pusher member including a gripping surface engageable with food articles when fed through the inlet feed tube; and wherein said central region of the cutter disc is separated from said outer peripheral region such as to act with said pusher member to reduce or inhibit rotation of the food article when engaged by the rotating blades of the outer peripheral region of the cutter disc.5. The appliance according to claim 1, wherein the two blades of said first group have substantially straight, slightly convex, diametrically-aligned cutting edges.6. The appliance according to claim 1, wherein said housing comprises a base including said drive and said outlet; a top cover including said inlet feed tube; and a locking bar pivotally mounted to said base and engageable with said top cover for locking said top cover to said base.7. A cutter disc for a juice extractor appliance having a feed tube through which food articles are to be fed for extracting juice therefrom;said cutter disc including means for mounting the cutter disc with respect to the feed tube, and being formed, on its surface to face the feed tube, with a first group of blades in a circular region centrally of the cutter disc, and with a second group of blades in an outer peripheral region around the central circular region; said first group of blades consisting of two blades located on opposite sides of said central circular region and diametrically aligned with each other and with the center of said central circular region; one of said blades extending diametrically across one side of said central circular region and terminating substantially at the center thereof, the other of said blades extending diametrically across the opposite side of said central circular region and terminating short of the center thereof; said second group of blades consisting of a plurality of lines of blades in said outer peripheral region radiating from said center circular region; said central region being separated from, and rotatable with respect to, said outer peripheral region. 8. The cutter disc according to claim 7, wherein the blades of said second group extend tangentially with respect to said center circular region.9. The cutter disc according to claim 7, wherein the blades of said second group radiate from approximately the mid-points of radial lines through said central circular region.10. The cutter disc according to claim 7, wherein the two blades of said first group have substantially straight, slightly convex, diametrically-aligned cutting edges.11. A cutter disc for a juice extractor appliance having a feed tube through which food articles are to be fed for extracting juice therefrom;said cutter disc including means for mounting the cutter disc with respect to the feed tube, and being formed, on its surface to face the feed tube, with a first group of blades in a circular region centrally of the cutter disc, and with a second group of blades in an outer peripheral region around the central circular region; said first group of blades consisting of at least one blade located on each of the opposite sides of said central circular region and diametrically aligned with each other and with the center of said central circular region; said second group of blades consisting of a plurality of lines of blades in said outer peripheral region radiating from said center circular region; said first group of blades being separate from, and rotatable with respect to, said outer peripheral region including said second group of blades such as to permit rotation of said outer peripheral region independently of said central region. 12. The cutter disc according to claim 11, wherein said first group of blades consist of two blades.
