Abstract

It comprises a characteristic device which allows variation in the direction or angle of incidence of the air flow so as to adapt it to the form of the vehicle. It is also simple and adaptable, allowing it to be incorporated in the nozzle without the need for practically any modification of the design and overall configuration thereof. The device comprises an outlet mouth bounded by profiled parts (15) which are hingeably coupled on facing pins (16), the air outflow angle being varied with the simultaneous movement of said profiled parts.

Description

DRYING NOZZLE FOR VEHICLE WASHING MACHINES

OBJECT OF THE INVENTION

The present invention, as expressed in the statement of this specification, refers to a drying nozzle 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 vehicle geometry, but which also presents a simplicity and adaptability that allow its integration into the nozzle without practically modifications in its design and general configuration.

BACKGROUND OF THE INVENTION

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

For example, this occurs in the invention patent 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 by having to 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 vehicle washing machines that is of the type that includes at least one side blower that injects air in a central area that can incorporate three sectors of exit of air: two inclined sections extreme that orient the air towards the sides of the vehicle and a third central section that orients to the part superior of

, vehicle, being in this area where the angulation or incidence of air output on the vehicle is of interest.

The invention is also applicable to nozzles that lack the first extreme air outlet sectors towards the sides of the vehicle. Thus, the invention incorporates a characteristic device integrated in an upper central area of the nozzle structure located above the air outlet of the central sector of said nozzle.

In this way, a hole located above the air outlet is used, just above the confluence of the air ducts that come from the blowers, which provides undoubted advantages as it practically does not affect the design of the nozzle.

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

For this, the device comprises a two-way actuator connected on a rocker arm connected by its ends to connecting rods, which in turn are connected to supports, of which the movable profiles that limit the outlet opening to orient the flow rate of air. Thus, when the actuator is moved in one direction or another, the movable profiles also move by varying the orientation of the air outlet according to the geometry of the vehicle.

Next to facilitate a better understanding This descriptive report and forming an integral part thereof are accompanied by figures in which the object of the invention has been shown as an illustrative and non-limiting nature. BRIEF DESCRIPTION OF THE DRAWINGS

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 comprises a support structure 1 that incorporates two side blowers 2 that inject air along a cross-sectional area 3 where air outlet sectors are distinguished: two inclined sections 4 that orient the air flow towards the sides of the vehicle and a central sector 5 that orients the air, by means of a characteristic device, towards the upper part of the vehicle, where it is here where the angle of incidence of the air on the vehicle is interested to vary .

The aforementioned device is integrated in the structure of the nozzle 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 come from the two side blowers 2 .

The device comprises a tandem cylinder 8 with its stems in opposition, so that one of them articulates at a fixed point 9 of the structure of the nozzle 1, while the other rod articulates at an off-center point 10 of a rocker 11 mounted on a centered axis 12. At the ends of the rocker 11 connecting rods 13 are connected to in turn with supports 14, of which parallel profiles 15 are integral that limit the mouth of the air outlet to orient the flow of air on the upper surface of the vehicle adapting to its geometry.

The parallel profiles 15 are in turn mounted on opposing articulation axes 16 arranged at the conventional central conical outlet 7 of the nozzle assembly.
