Device for cleaning a detection surface of a detection device
The present invention mainly relates to a device for cleaning a glazed surface of a detection device for a vehicle, the cleaning device includes at least two parts fitted one against the other which at least in part delimit a network for distributing a cleaning liquid and a circuit for channeling an air flow, the network for distributing the cleaning liquid being distinct from the circuit for channeling the air flow.
1 . A cleaning device for cleaning a glazed surface of a detection device for a vehicle, the cleaning device comprising at least two parts fitted against one another and which at least partly delimit a cleaning liquid distribution network and an air flow ducting circuit, the cleaning liquid distribution network being distinct from the air flow ducting circuit, the air flow ducting circuit includes an air flow outlet on an external surface of the cleaning device, with the cleaning liquid distribution network including at least a pipe, a chamber, a cleaning liquid spray outlet being hydraulically connected to the pipe by the chamber, the chamber and the spray outlet being delimited by a first part and a second part of the at least two parts, whereas the pipe is delimited by just the second part, with the first part including a first surface and the second part including a second surface and a portion of the first surface being in contact with a portion of the second surface to form at least the cleaning liquid spray outlet.
2 . The cleaning device as claimed in claim 1 , wherein at least one dimension of the cleaning liquid spray outlet is an increasing dimension, the at least one dimension being measured perpendicular to a direction of flow of the cleaning liquid.
3 . The cleaning device as claimed in claim 2 , wherein the at least one dimension increases from an upstream end portion of the cleaning liquid spray outlet as far as a downstream end portion of the cleaning liquid spray outlet in the direction of flow of the cleaning liquid.
4 . The cleaning device as claimed in claim 1 , wherein the first part and/or the second part contributes to delimiting at least one conduit extending into the chamber and opening at the cleaning liquid spray outlet, the first part or the second part bearing a spray wall extending in a plane secant to a main direction of elongation of the at least one conduit.
5 . The cleaning device as claimed in claim 4 , wherein at least one dimension of one end of the at least one conduit at the cleaning liquid spray outlet is an increasing dimension, increasing toward the cleaning liquid spray outlet, the at least one dimension being measured perpendicular to a direction of flow of the cleaning liquid within the at least one conduit.
6 . The cleaning device as claimed in claim 1 , wherein the air flow ducting circuit includes at least a duct, a cavity, the air flow outlet being aeraulically connected to the duct by the cavity, the cavity and the air flow outlet being delimited by the first part and the second part, whereas the duct is delimited by just the second part.
7 . The cleaning device as claimed in claim 1 , wherein the second part includes at least one separation element separating the cleaning liquid distribution network from the air flow ducting circuit, the first part includes at least one separation member able to collaborate with the separation element so as to separate the cleaning liquid distribution network from the air flow ducting circuit in a fluidtight manner.
8 . A detection assembly comprising at least one detection device including at least one detection surface and a cleaning device for cleaning the detection surface, with the cleaning device including at least two parts fitted against one another and which at least partly delimit a cleaning liquid distribution network and an air flow ducting circuit, the cleaning liquid distribution network being distinct from the air flow ducting circuit, the air flow ducting circuit includes an air flow outlet on an external surface of the cleaning device, with the cleaning liquid distribution network including at least a pipe, a chamber, a cleaning liquid spray outlet being hydraulically connected to the pipe by the chamber, the chamber and the spray outlet being delimited by a first part and a second part of the at least two parts, whereas the pipe is delimited by just the second part, with the first part including a first surface and the second part including a second surface and a portion of the first surface being in contact with a portion of the second surface to form at least the cleaning liquid spray outlet.
