I claim the ornamental design for a bidet, as shown and described.
FIG. 1 is a perspective view of an embodiment of the claimed design;
FIG. 2 is a front view of the claimed design shown in FIG. 1;
FIG. 3 is a rear view of the claimed design shown in FIG. 1;
FIG. 4 is a top view of the claimed design shown in FIG. 1;
FIG. 5 is a bottom view of the claimed design shown in FIG. 1;
FIG. 6 is a side view of the claimed design shown in FIG. 1; and,
FIG. 7 is another side view of the claimed design shown in FIG. 1.
In the drawings, the broken lines form no part of the claimed design. The evenly spaced dashed lines show portions of the bidet, and the dot and dashed lines indicate a boundary between the claimed and unclaimed portion of the design.
