Definitions
- the present invention relates to the washing of dirty surfaces such as floors, walls, ceilings on the floor. using a device fitted to a motor vehicle.
- Such devices used to date for cleaning floors have a fixed washing ramp with high flow rate and low cold water pressure.
- the boom has a large number of nozzles to cover by movement of the vehicle a given working area.
- Hot water can not be used in these known devices because of the flow, important water (6 to 20 m3 / h) necessary.
- the vehicle comprising such a device has a chassis which supports a large tank to provide, due to the high water flow, a certain operating autonomy for the vehicle. In theory, this tank could be filled with hot water before the vehicle leaves for a cleaning tour, but it would also be necessary to provide good insulation of this tank so that the water temperature does not drop too much over time, especially in winter.
- a hot spring should be provided at a specific location, which would limit autonomy and. use of this vehicle.
- the known washing devices comprise a fixed ramp which delivers only jets of fixed directions under a low pressure of cold water and consequently these jets do not have a cleaning effect on the soiled surfaces of fatty substances such as oils or fats.
- the invention relates to a washing device fitted to a motor vehicle, this device having a strong cleaning effect on surfaces including those soiled with fatty substances.

- the pressure is provided by the pumping means which advantageously include a high pressure positive displacement pump for this purpose.
- the high power of the jet makes it possible to reduce its cross section therefore the flow rate of each nozzle equipping the rotary arm. This results in a particularly low consumption of hot water and a long autonomy of the cleaning vehicle.
- the rotary arm is arranged substantially horizontal and has a substantially vertical axis of rotation, said arm is located under the vehicle, each nozzle being oriented to direct a jet of hot water to the floor to be cleaned.
- This device also includes means for adjusting the height of the rotary arm relative to the floor to be cleaned between a cleaning position and a tent position.
- the device is particularly suitable - well for cleaning the roadways, landing strips for aircraft, and other oily soils.
- the vehicle is provided with a single rotary arm and the device is characterized in that it comprises an articulated orientable and deployable member having the rotary cleaning arm disposed at its free end to clean walls, ceilings, floors and surfaces of various orientation.
- each rotary arm has an axis of rotation passing through its middle and is provided with a nozzle at each of its ends, the two nozzles being substantially identical, of triangular flat shape, and having. the same average general plan.
- the nozzles deliver two diverging substantially co-planar flat jets which have different angles of attack from the surface to be cleaned. These jets can attack the opposite edges of a surface element comprising facets perpendicular to the general plane of this surface, such as pavers or gratings.

- hoses 220, 221, 222 pass inside the first segment 204 and then exit to span the axis of the rotary jacks 208, 209 to pass back inside the second segment 207, then from the hollow shaft of the rotary jack. 211 to join the interior of the third segment 210 and from there after having stepped over the rotary actuator 213 connect respectively to the hydraulic motor 170 and to the rotary joint 132.
- the electric cables (not shown), connected to the detector elements 217 follow the same path as the hoses 220, 221, 222 inside the articulated arm.
- the protective casing 110 rests in the vicinity of the rear roof of the vehicle by folding backwards the articulated arm 200, by pivoting around the jacks upside down 208, 209.
- This provides the lowest overall height of the vehicle thus equipped.
- the deployed length of the articulated arm measured from the end 203 of the post 202 and going to the edge of the casing which is in operation in relation to the surface to be cleaned, is close to the overall length of the vehicle.

- the vehicle, stationary the pilot can carry out the cleaning of circular zones of grounds, walls, ceilings by movements controlled by the articulated member.
- the movement of the vehicle allows the washing in strips extending in the direction of progression of the vehicle in slow forward (about 1.5 km / hour).
