Description

The innovation relates to a device for drying vehicles according to the preamble of claim 1.

A known drying device of the type mentioned at the beginning has two column-shaped housings, each with a fan, which are each provided with a vertically running slot nozzle. The two column-free housings are supplemented by a horizontally running housing, which is provided with a downwardly directed slot nozzle. In this known drying device, the effect of the heat removal on the vehicle surface is relatively poor, since the air jets emerging from the slot nozzles dissolve at a relatively short distance from the air outlet and therefore swirls as air on the vehicle surface and hits it at a low speed.

Another known drying device consists of a U-shaped frame with round nozzles directed at the side and top of the vehicle surface. The air jets emerging from the round nozzles only dissipate at a greater distance from the nozzle outlet than is the case with slot nozzles, which results in a better drying effect with this device, but this is still not satisfactory. The reason for this is that the air jets emerging from the upper and side nozzles partially collide with one another before they hit the vehicle surface, which leads to jet deflections and air swirls, which means that the water on the vehicle surface is only partially blown off. Depending on the type of vehicle, strip-shaped areas can be seen on the vehicle surface to which water droplets still adhere.

The task is to design the device for drying vehicles in such a way that, with a relatively simple structure, the moisture on the vehicle surface can be effectively blown off

explained in more detail. They show:

Fig. 1 A top view of the drying device \ and

) Fig. 2 a vertical section through a housing of this

Drying device.

According to Fig. 1, the vehicles to be dried pass through a passage formed between two column-shaped housings 1 in the direction of arrow 2. The two housings have several round nozzles 4 arranged one below the other on their front wall 3. Viewed from above, the nozzle axes 5 form a wedge-shaped angle, the tip of which points in the opposite direction to arrow 2. This nozzle arrangement is known per se, but in the known device the nozzles do not consist of round nozzles 4 but of vertically running flat nozzles.

In the direction of flow 2 behind the housings 1 there is another housing 7 and another housing offset therefrom. The housings 7, 8 also have round nozzles 9 arranged vertically one below the other, the axes of which, when viewed from above, are arranged perpendicular to a vertical plane 11 which runs in the direction of flow 2 of the vehicles.

! The housings 1, 7, 8 each have an almost square cross-section. A fan 12 is arranged at the bottom of the housing, which preferably has a silencer in its intake duct. Vertically offset from one another on the housing wall 3,

the round nozzles 4 A to 4 E are arranged on the other. The axes 5 A to 5 E of these round nozzles 4 A to 4 E are each inclined downwards. In the embodiment shown, the inclination of the axes 5, in each case relative to a horizontal, increases from top to bottom. For example, the axis 5 A of the top nozzle 4 A is inclined by approximately 15° to the horizontal, while the inclination of the axis 5 E of the lower nozzle 4 E is approximately 40°. In the top view according to Fig. 1, all axes 5 A to 5 E are arranged in a vertical plane defined by the axes 5. In the respective vertical plane*, the axes 5 A to 5 E run approximately fan-shaped.

The air jets emerging from the nozzles 4 A to 4 E of the two housings 1 thus form two air curtains which run in the vertical planes formed by the axes 5 and which meet at the tip 6, the air flow in each curtain being directed from top to bottom in accordance with the inclinations of the axes 5 A to 5 E. If a vehicle moves in the direction of the arrow 2, these air curtains hit the vehicle surface and push the water adhering to the vehicle surface backwards and downwards at the same time. This also applies to the roof surface, as at least the upper nozzles 4 A run above the roof surface.

The nozzles 4 A to 4 E can be designed so that their inclination to the horizontal can be adjusted, as is indicated for the nozzle 4 A. This consists of two pipe sockets which are connected to one another via a horizontal joint 13.

As the passage continues in the direction of arrow 2, a vehicle to be dried first reaches the housing 7 and then the housing 8, which are arranged on both sides of the passage, but offset from one another in the direction of arrow 2. These housings 7, 8 can be lower than the housings 1 and have a smaller number of round nozzles. The nozzles 9 are inclined downwards, just like the nozzles 4,

however, when viewed from above, they run perpendicular to the vertical plane 11. These nozzles 9 are used to blow off water

in the lower part of the vehicle, especially in the area of the bumpers. As a result of the offset of the housings 7, 8, it is also achieved here that the air jets emerging from the nozzles do not collide with one another.

The term round nozzle was used above for the nozzles 4, 9. The nozzles can also have a shape that differs from the circular one. ahupTrhenHon Qnorcrhnntt aufuoicpn . up &iacgr; c pn ieHnrh inupi I c — ... ...._.. — _.. —— _.__ __ —— ..._ _ _ .. ^ -._.__.. _,____.. _,_.._.__

a tubular nozzle mouthpiece.

Inside the housings 1, 7, 8, there is an air duct 14 that tapers towards the top and is bordered on all sides by a layer of sound-absorbing material. Air baffles that lead to the respective nozzles can be arranged in this air duct that tapers towards the top.

Fig. 3 shows an alternative construction of a housing, whereby only the upper part of the housing is shown in Fig. 3. According to this embodiment, instead of a radial fan 12, an axial fan 12 A is used, which is arranged on the upper side of the housing and which sucks in air via openings 16 on the upper wall of the housing. The sucked-in air is then conveyed into the air duct 14 A, which in this embodiment tapers downwards. The round nozzles 4 then branch off from this air duct 14 A. Both the axial fan 12 A and the air duct 14 A are surrounded on all sides by a layer 15 of a sound-absorbing material. With the resulting air flow, the air baffles 16 can be dispensed with.
