Bowl for spraying a coating product, rotary spraying apparatus including such a bowl, and method for cleaning such a spraying apparatus

A bowl for spraying a coating product, intended to be integrated into a rotary spraying apparatus for a coating product, the rotary spraying apparatus comprising a turbine to drive the bowl about an axis of rotation and a body that defines the axis of rotation and which comprises orifices for ejecting shaping air arranged in a crown, the bowl comprising:

• a body centered on an axis, comprising:
• an inner radial surface for distributing the coating product to a spraying edge;
• and
• an outer radial surface, radially surrounding said inner radial surface, wherein a deflector integral with the bowl protrudes only out of the outer radial surface as a triangular protrusion with two concave surfaces and directs, at least partially, a flow of cleaning product flowing along the outer radial surface towards the spraying edge, towards a front face of the body of the rotary spraying apparatus where the orifices are located.
