Description

Drying nozzle for washing machines vehicles.

Object of the invention

The present invention, as expressed in the set forth in this specification, refers to a nozzle of drying for vehicle washing machines that incorporates a characteristic device that allows to vary the orientation or angle of incidence of the air flow, adapting it to the geometry of the vehicle, but that also presents a simplicity and adaptability that allows its integration into the nozzle without practically modifications in its design and configuration general.

Background of the invention

Drying nozzles are currently being used in which the air outlet is mobile to adapt to the vehicle geometry In practice it has been proven that the drying performance increases if the air flow adopts certain angle of incidence with the wet surface of the vehicle.

For example this occurs in the patent of invention WO 2006/027083, where the nozzle provides a kind of cylindrical nozzle that rotates on a central axis, to distribute the air flow with different angles.

All these known systems have a great impact on the design of the nozzle, which becomes really complex to have than adapt its most important parts to this mobile mechanism.

Description of the invention

In order to achieve the objectives and avoid the drawbacks mentioned in the previous sections, the invention proposes a drying nozzle for washing machines of vehicles that are of the type that include at least one blower side that injects air into a central area that can incorporate three air outlet sectors: two extreme inclined sections that Orient the air towards the sides of the vehicle and a third section central that guides the upper part of the vehicle, being in this area where the angulation or incidence of Air outlet over the vehicle.

The invention is also applicable to nozzles that they lack the first extreme air outlet sectors towards The sides of the vehicle.

Thus, the invention incorporates a characteristic device integrated in a central upper area of the nozzle structure located above the outlet of air from the central sector of said nozzle.

It takes advantage of a hole located above the air outlet, just above the confluence of the air ducts that come from blowers, which brings Undoubted advantages by practically not affecting the design at all of the nozzle.

The characteristic device will guide  in parallel mobile profiles that limit the mouth of central air outlet to direct the air flow with the angle required more profitable and advantageous.

For this, the device comprises an actuator two-way connected on a rocker associated by its ends to paths connecting rods these in turn to supports, of which the mobile profiles that limit the outlet opening to guide the air flow.

So, when the actuator moves in one or another way the mobile profiles move also varying the air outlet orientation according to the geometry of the vehicle.

Next to facilitate a better understanding of this descriptive report and being an integral part of the same accompany some figures in which with character illustrative and not limiting the object of the invention.

Brief description of the drawings

Figure 1.- Shows a perspective view of The drying nozzle for vehicle washing machines, purpose of the invention. It incorporates a characteristic integrated device to direct the centered air flow with one more orientation advantageous

Figure 2.- Shows a cross-sectional view of the device of the invention.

Figure 3.- Shows a schematic view of the device represented in the previous figure.

Description of the preferred embodiment

Considering the numbering adopted in the Figures, the drying nozzle for vehicle washing machines it comprises a support structure 1 that incorporates two blowers lateral 2 that inject air along a transverse zone 3 where air outlet sectors are distinguished: two sections inclined 4 that orient the air flow towards the sides of the vehicle and a central sector 5 that guides the air, by means of a characteristic device, towards the top of the vehicle, being here where it is interesting to vary the angle of incidence of the air on the vehicle

The aforementioned device is integrated into the nozzle structure 1 in its upper centered area 6 taking advantage of a gap above the central air outlet 7, just above the confluence of the air ducts that They come from the two side blowers 2.

The device comprises a tandem cylinder 8 with their stems in opposition, so that one of them articulates at a fixed point 9 of the structure of the nozzle 1, while the another rod articulates at an offset point 10 of a rocker 11 mounted on a centered axis 12.

At the ends of the rocker 11 some are connected  connecting rods 13 that in turn connect with supports 14, of which parallel profiles 15 which limit the mouthpiece are integral of the air outlet to orient the air flow over the upper surface of the vehicle adapting to its geometry.

The parallel profiles 15 are mounted to their time on articulating axes facing 16 arranged at the Central conventional conical outlet 7 of the nozzle assembly.
