Food processor including potato peeling disc system and method
A potato peeling disc for peeling potatoes has a central opening formed by an inner contour of the potato peeling disc. A surface of the potato peeling disc comprises a plurality of teeth. The teeth have an orientation such that potatoes are peeled by the teeth by rotating the potato peeling disc in a first direction of rotation about a central axis which is coaxial with the central opening.
1 . A potato peeling disc for peeling potatoes, wherein the potato peeling disc has a central opening formed by an inner contour of the potato peeling disc, wherein a surface of the potato peeling disc comprises a plurality of teeth having an orientation such that potatoes are peeled by the teeth by rotating the potato peeling disc in a first direction of rotation about a central axis which is coaxial with the central opening, wherein the potato peeling disc is configured to be manually releasably attached to a mixing or a chopping tool, and wherein the inner contour forms, by means of a U-shaped cut-out, a latch arm extending parallel to the central axis, wherein the latch arm includes a latching lug projecting radially in the direction of the central axis, such that during installation the latching lug grinds along a rotationally symmetrical body with an outer diameter of exactly 17 mm in the direction of the central axis, and wherein the rotationally symmetrical body defines a recess and during installation the latching lug is configured to engage in the recess.
2 . The potato peeling disc of claim 1 , wherein the potato peeling disc has a wave-like shape.
3 . The potato peeling disc of claim 1 , wherein the potato peeling disc comprises a plurality of slits.
4 . The potato peeling disc of claim 1 , wherein the teeth are ramp-like or and/or have a rectangular ramp shape.
5 . The potato peeling disc of claim 1 , wherein the teeth have a slope angle α of at least 140° and at most 175° in the direction of the respective orientation measured from the adjacent surface of the potato peeling disc.
6 . The potato peeling disc of claim 1 , wherein the potato peeling disc defines a plurality of annular tracks disposed coaxially to the central axis at an equal radial distance from each other.
7 . The potato peeling disc of claim 1 , wherein the inner contour forms the central opening such that the potato peeling disc is attachable with the central opening onto the rotationally symmetrical body having the outer diameter of exactly 17 mm, and wherein, when the potato peeling disc is in the attached state, the inner contour rests against the rotationally symmetrical body over a length of at least 10 mm in the direction of the central axis.
8 . A food processor comprising:
a food preparation vessel;
a heating element and a mixing or chopping tool for preparing a food in the food preparation vessel; and
a potato peeling disc having a central opening formed by an inner contour of the potato peeling disc, wherein a surface of the potato peeling disc comprises a plurality of teeth having an orientation such that potatoes are peeled by the teeth by rotating the potato peeling disc in a first direction of rotation about a central axis which is coaxial with the central opening, wherein the potato peeling disc is configured to be manually releasably attached to the mixing or chopping tool,
wherein the inner contour forms, by means of a U-shaped cut-out, a latch arm extending parallel to the central axis, wherein the latch arm includes a latching lug projecting radially in the direction of the central axis, such that during installation the latching lug grinds along a rotationally symmetrical body with an outer diameter of exactly 17 mm in the direction of the central axis, and wherein the rotationally symmetrical body defines a recess and during installation the latching lug is configured to engage in the recess.
