- the external radial surface of the bowl is provided with a deflector intended to direct, at least partially towards the crown of the body, a flow of product of cleaning which circulates along this external radial surface, in the direction of the spraying edge.
- the deflector makes it possible to return cleaning product to the crown of the body into which the air ejection orifices open out, which makes it possible to clean this crown of any deposits of coating product which are there are trained, in a particularly simple, fast and efficient way.
- the front face of a projector equipped with a bowl according to the invention can be effectively cleaned
- such a projector can incorporate one or more of the following characteristics:
- the deflector forms an angular rupture zone of the external radial surface.
- the deflector defines, in a plane radial to the axis of rotation and with the outer radial surface upstream of the deflector, a dihedral at the apex between 10 ° and 170 °, preferably between 45 ° and 135 °.
- the deflector is located, along the external radial surface, at a non-zero distance from the spraying edge, this distance being preferably greater than 5mm, more preferably still greater than 10mm.
- the deflector is equipped with channels for guiding the flow of cleaning product towards the crown.

- the upstream corresponds to a direction turned towards the source of the coating product or of the cleaning product, on the left of FIGS. 1 to 7, while the downstream corresponds to an opposite direction, turned towards the spray edge 63, on the right of these figures.
- connection in rotation between the rotor 42 of the turbine 4 and the bowl 6 can take place by magnetic attraction, in particular by means of a magnet 47 integrated in this rotor and a ferromagnetic ring 67 integrated in the bowl 6, at its external radial surface 65.
- other means for securing in rotation between the rotor 42 and the bowl 6 can be used, for example means for securing by screwing.

- the crown 88 is generally perpendicular to the axis X8, that is to say form in a plane radial to the axis X8 as that of the figures, an angle between 80 and 100 ° with the axis X8.
- the problem which the present invention more particularly resolves relates to the cleaning of this crown 88, especially when changing the coating product.

- the deflector 66 is in one piece with the bowl 6 and can be produced by machining the external radial surface 65.
- this deflector is attached to the body 60 by welding, bonding, additive manufacturing , screwing or any other suitable mechanical assembly means.
- the deflector extends continuously over the entire periphery of the external radial surface 65, that is to say all around the body 60.

This distance is not zero, preferably greater than or equal to 5 mm, of preferably still greater than 10 mm.
- the cleaning of the headlight 2 comprises, in addition to the conventional steps of cleaning the internal radial surface 61 by injecting cleaning product via the conduit 10, a first step represented by the arrows F2 and consisting in directing the flow of product of cleaning towards the upstream portion 652 of the external radial surface 65 of the bowl 6, while the latter is rotated by the turbine 4, around the axes X6 and X8 combined.
- This first step is already known for certain projectors in which the external radial surface of the bowl is cleaned.
- This process includes an additional step during which the cleaning product is allowed to flow over the portion 652 up to the level of the deflector 66, to the point that it is then deflected or redirected towards the crown 88, which represents the arrows F4.
- This second step is advantageously broken down into two sub-steps respectively represented in FIGS. 2 and 3.
- the orifices 82 are not supplied with pressurized air. This allows the flow of cleaning product deflected by the deflector 66 to effectively clean the entire crown 88, including the part 882 of this crown located radially outside the orifices 82.
- the orifices 82 are supplied with pressurized air, to the point that jets of pressurized air exit from these orifices 82, as represented by the arrow F1, which has the effect to reduce the flow of cleaning product towards the downstream portion 654 of the surface 65, as shown by the arrow F6.

- a flow of cleaning product as represented by the arrow F2 in FIG. 6 can penetrate into the different portions of channels 666A and be redirected via the portions of channels 666B to the crown 88 which can thus be effectively cleaned .
- the arrow F4 shows the path of the cleaning product inside the deflector 66 and its change of direction within a channel 666.
- open channels 666 are formed by notches formed on the upstream surface 662 of the deflector 66, which is defined as in the first embodiment.
- the channels 666 are advantageously regularly distributed around the axis X6.
- the number and the distribution of the channels 666 of the second and third embodiments can be chosen according to the number and the distribution of the outlet orifices 82. This is however not compulsory.
