DRYER FOR DRYING CARS IN CAR WASHERS

The invention relates to a drying device for drying cars in car washes, in particular portal-5 washing machines, having a horizontal fan housing arranged in a portal-like cross-beam frame, at least one fan closed in the housing and provided with a a slit nozzle, wherein the fan housing together with the slit nozzle and the fan is mounted on the frame as a unit in a height-moving manner and its height position is controlled by a control device depending on the shape of the car.

Such a drying device is known from DE-GM 71 19 078. In one application, an assembly consisting of a fan housing, a slot nozzle and a fan is arranged at one end of a two-arm, portal-pivotally mounted lever, the other end of which lever supports a counterweight. This imaging device has a relatively large construction length due to the large length required by the ♦ lever arm. According to another embodiment, the fan-nozzle unit must be vertically mounted via a trolley; 25 movable to a portal-like frame. This also leads to space problems. Namely, if the fan housing with the fan is guided to move exactly below the cross member, then it gives a higher structural height, as the fan housing sometimes has to be driven up 30 so that even taller vehicles such as minibuses * · .. * and vans still fit under the slit nozzle. In this case: there is still a crossbar above the fan housing.

. ···. Due to the higher construction height thus required, the dryer 35 is most often no longer suitable for existing: V washrooms or service halls. Similarly, the case where the fan housing is slightly deflected relative to the plane of the frame 2 f 82647 so that it can be moved forward or backward in front of or behind the crossbeam and parallel to it. In this case, the structural length of the dryer increases the dimensions of the fan housing or portal 5 in the longitudinal direction of the vehicle. Dryers with a larger construction length are very limited in their installation possibilities, because conventional control dimensions do not allow larger construction dimensions of the dryer. In addition, in portal washing machines, a washing machine with rotating washing brushes 10 is arranged right next to the drying machine. Water droplets spun off from the rotating scrub brushes can enter the slit nozzle and eventually be detrimental to the drying process, allowing them to drip down on the partially dried pin-15 during drying.

The object of the invention is to improve a drying device of the known type for drying cars in car washes, so that the imaging device has the lowest possible construction height and thus also better suited to existing washing or service halls.

This is achieved according to the invention in that the body has a housing-like, hollow and downwardly open cross-section with a cross-section larger than the cross-section of the fan housing, and that the fan housing 25 can be driven completely inside the cross-section from below.

This shape of the drying device reduces the space requirement, since the fan housing together with the fan and the nozzle can be driven completely inside the cross member and does not require additional space in the test direction or width direction of the device in this driven position. In addition, the complete possibility of entry, especially in portal washing devices, has the advantage that the drying device does not interfere optically or mechanically with other functions, e.g. washing. Especially when the fan housing 35 and the slot nozzle have been driven into the cross member, Rois - j light cannot enter the slot nozzle during washing. Such water would drip out of the 3 82647 slit nozzle during drying and could be detrimental to the drying process.

A preferred embodiment of the invention is such that a fan is arranged at each end of the fan housing, and the fan housing is likewise arranged to be driven into the crossbeam. By using two fans, each of them can be smaller than one single. These smaller fans are easier to place inside the crossbar. Each individual fan produces half of the air in the slot nozzle. The distance that air passes from the fans to the outlet of the slit nozzle is thus reduced to a minimum.

The invention will be described in more detail below, in connection with the exemplary embodiments shown in the drawing. They present:

Figure 1 is a cross-sectional view of the drying device with a portal structure taken along line I-I in Figure 2.

Figure 2 is a longitudinal section along the line II-II in Figure 1.

A portal 20, stationary relative to the vehicle in the direction of arrow B, back and forth movable, · the frame (also referred to as a portal) 1 is arranged work transfer direction of the body 1B in the cross-fan casing 2. The fan housing both. A fan 3 is arranged at 25 ends, which sucks the drying air from the surrounding air. The fan housing 2 is divided into two halves by a central partition wall. On the underside of the fan housing there is a slit nozzle 5 in which a downwardly directed outlet opening 5a is arranged. As shown in Fig. 2, the slit nozzle 5 practically forms the bottom part in the fan housing 2.

: The horizontal cross-boom Ib of the portal 1 is housing-shaped and hollow, and has an opening 16 on its underside. This opening 16 and the cross-section of the cross-boom Ib 35 are dimensioned with respect to the dimensions of the fan housing 2 and its connected parts so that the fan housing 2 as well as the slit nozzle 5 can be completely driven across the boom 82647 4. In this way, during the washing phase, the fan housing 2 and the slit nozzle 5 are protected from splash water.

The fan housing 2, the fans 3 and the horizontal slot nozzle 5 form a unit which is mounted on the frame 1 in a vertically displaceable direction V. For this purpose, the fan housing 2 is connected to two side guide rollers 6, each guided by guide rails 7 in two flexible traction elements 8, e.g. a toothed belt or chain. At one end of each traction member 8 there is a counterweight 9. Each flexible traction member 8 is guided through a gear or gear 10, each gear 10 being arranged on a common horizontal drive shaft 11. The drive shaft 11 is driven by a freewheel 13 connected by a control motor 12, such as described in more detail in DE-OS 2,518,718. The control motor 12 and the freewheel 13 are formed in such a way that each of the flexible traction members 8 20 can be operated only in such a way that the fan housing 2 is raised. The control motor 12 is then adjusted from a light boom or a corresponding non-contact sensing device. The weight of the fan housing 2, including *: its associated parts, is not completely balanced by the counterweights 9, so that it has a small overweight relative to the counterweights. Thanks to this overweight and the free switch 13, the fan housing 2 and the slit nozzle 5 can be lowered.

Normally, the control motor 30 is continuously operated in the first direction of rotation which would drive the drive shaft in the direction S. However, since in this direction of rotation the freewheel 13 releases and no drive connection will be cut off by the surface of the car to be dried *. This engages the control motor 12 in its second direction of rotation, where the freewheel 13 appears to lock. Thus, the drive shaft 11 is driven in the direction H and thus the fan housing 2 and the slot nozzle 5 are raised When the light boom receiver again receives the light beam, the direction of rotation of the control motor 12 is reversed again to the first direction of rotation, so that no further elevation occurs. In this way, the slit nozzle 5 10 is always adjusted close above the upwardly facing surfaces of the car along them. It is expedient, as can be seen from Figure 2, to arrange two light beams 14 on each side of the slit nozzle 5 and slightly below it. For the case that the light beam control 15 would act, is additionally on both sides of the nozzle 5, the outlet opening 5a in the immediate vicinity of the two navigation list, e.g. shock wave switch 15, which contact with the car immediately switch off the use of the portal.
