is solved according to the invention in that a protective shield extending essentially over the entire width of the washing and/or liquid application device is movably mounted on the portal, which can be moved by means of a servomotor up to the area below the washing and/or liquid application device and into the area below the blowing nozzle.

During washing or applying liquid to

TO the vehicle's overflow protection shield is brought into the area below the horizontal blowing nozzle. It thus protects the blowing nozzle from splashing water so that it remains dry. After the washing process or the liquid application has been completed, the protective shield is brought into its second position in the area below the washing and/or liquid application device by means of the servomotor. This allows the water to be removed from the washing device, for example a washing brush, or the liquid application device, for example a

2D spray pipe, dripping down, is caught by the protective shield. This prevents any water dripping down onto the vehicle surface during the drying process, which results in a particularly good drying effect. Preventing dripping water is particularly important when drying takes place in two stages, i.e. during the forward and return travel of the portal.

A particularly advantageous embodiment of the invention consists in that the protective shield is attached to at least one swivel arm _which can be pivoted about a horizontal axis extending transversely to the direction of movement of the portal and arranged between the spraying and/or liquid application device and the blowing nozzle.

Portal is mounted. In this embodiment of the invention, the protective shield is designed as a protective flap, so to speak. This embodiment is particularly simple in construction and also particularly reliable in operation.

Further advantageous embodiments of the invention are characterized in the remaining subclaims.

The invention is explained below with the aid of two detailed drawings in more detail below. They show:

Figure 1 shows a cross section of a first embodiment B in the portal bending direction, Figure 2 shows a cross section of a first embodiment BB in the portal bending direction.

The portal 1, of which only the upper part is shown, can be moved forwards and backwards on rails in the longitudinal direction of the vehicle (not shown) to be washed and dried. A horizontal washing and/or liquid application device which extends over the entire width of the vehicle is arranged on the portal 1. This washing and/or liquid application device can expediently be raised and lowered by means of a motor 3 so that it can follow the contour of the vehicle. The washing and/or liquid application device 2 can be designed in various ways. For example, as shown in Figure 1, it can have several horizontal pipes k which are provided with nozzles or bores. These pipes k are used to apply liquids to the vehicle surface. The liquids are usually water which can be enriched with additives such as a chemical drying aid, Dachs or the like. In addition, one of the tubes k is intended to:

Spray dirt-removing shampoo onto the vehicle surface. To wash the vehicle, water can also be sprayed onto the surface under high pressure from the spray gun*

According to Figure 2, the horizontal washing and/or liquid application device can comprise a washing brush 5 rotating about a horizontal axis H, which is shown in the resting state in Figure 2. In addition to this washing...

extending axis A. This pivot shaft 12 or axis A is arranged between the spray and/or liquid application device 2, ²¹ and the blowing nozzle 7. A servomotor 13 is provided for rotating the pivot shaft 12.

The protective shield 10 expediently has an edge 10a which is raised relative to the shield plane and which is advantageously provided on all sides of the protective shield. If necessary, the protective shield 10 could also have a channel- or trough-shaped cross-section. The raised edge 10a is arranged on the protective shield 10 in such a way that, in the dash-dotted position shown in Figures 1 and 2, it is directed upwards below the Idasch and/or liquid application device 2, 2'.

!During the washing process, in which the portal can be moved back and forth in direction B relative to the stationary vehicle one or more times, the blowing nozzle is completely retracted into the mast 9 which is open at the bottom. During washing, the protective shield 10 is pivoted into a position below the blowing nozzle 7 and closes off the box 9 at the bottom. This prevents splash water from reaching the blowing nozzle during the washing process. After the washing process has ended, the protective shield 10 is pivoted by means of the servomotor EB 13 into its second position shown in dash-dotted lines in the area below the washing and/or liquid application device 2, 2'. In this way, the protective shield serves as a collecting channel for dripping water that could drip from the ash and/or liquid collection device during the subsequent drying process, during which the portal is also moved back and forth one or more times in direction B relative to the vehicle. It is _therefore

ensured that no water or washing liquid can drip down onto the vehicle from the washing and/or liquid application device 2, ²¹ during the drying process. Since the blower nozzle 7 is also covered by the protective shield 10 during the washing process, no splash water can reach the blower nozzle, so that it is also ensured that no water can drip from the blower nozzle 7 onto the vehicle surface during the drying process. Since the protective shield can be alternately brought into the area beneath the washing and/or liquid application device and also into the area beneath the blower nozzle 7, the device that is not in use is alternately covered with one and the same protective shield. However, both covers serve the same purpose, namely to prevent water from dripping down onto the vehicle surface during the drying process.

The protective shield could also be mounted in a different way, for example by being mounted on the portal so that it can be moved horizontally in the direction of movement. However, the pivoting mounting of the protective shield used in the embodiments shown in the drawing is particularly simple and reliable. It also has the advantage that the water collected by the protective shield during the drying phase is automatically drained when the protective shield is pivoted back from its dot-dash position to the position shown in the diagram before starting a new washing process.
