Abstract

In a method for washing and drying motor vehicles the following steps are used in succession: the entire vehicle surface is sprayed mechanically with water, optionally with the addition of dirt-loosening agents, a cleaning foam is applied mechanically to the vehicle surface, the vehicle surface is cleaned manually using a brush, a sponge, a washing glove or the like to rub the cleaning foam over the vehicle surface, water is sprayed mechanically onto the vehicle surface to rinse off the remaining cleaning foam and the loosened dirt, and the vehicle surface is dried mechanically.

Description

The invention relates to a method for washing and drying NEN of motor vehicles.

Motor vehicles, especially cars and minibuses as well Vans, these days are made on two different ones Species washed. In automatic car wash the vehicle is moistened with water one after the other tet, then applied cleaning foam and then washed by several rotating brushes. It then follows a mechanical rinsing process and possibly also the opening wear wax. Finally, the vehicle is replaced by a Fan drying machine dried. To carry out of this machine washing and drying process Continuous washing systems or portal washing systems are known. Represented a larger number of vehicle owners however, believes that by the rapidly rotating Wash brushes will damage the paint surface. There is also older vehicles that work in machines the car washes poorly or not at all can be washed because protruding parts of the Wash brushes can be gripped and torn off.

The second way to wash automobiles is that the whole vehicle was washed and dried by hand will, however, which takes a relatively long time takes. Manual drying, in particular, ever requires a lot of time. There are also recently also self-service car washes, where the driver a high pressure washing gun is available to the owner with which he puts water under high pressure can spray the vehicle surface. Drying the However, the vehicle must be done by hand. The cleaning the effect of high pressure water is low and also there is a risk that the high pressure water from the driving  injected back onto the surface of the tool and the driver's clothing tool owner soaked and dirty.

The invention is therefore based on the object, a Ver drive to the washing and drying of motor vehicles create, which the rapid cleaning and drying of the Motor vehicle with the greatest possible protection of the paint enables.

The invention is characterized by a combination of standing procedural steps, which are consecutive be turned:

• a) the entire vehicle surface is machined with what water, if necessary with the addition of dirt-removing agents Sprayed agents
• b) a Reini is mechanically on the vehicle surface applied foam,
• c) the vehicle surface is manually by means of a Brush, a sponge, a washing glove or Like. With rubbing the cleaning foam on the Vehicle surface cleaned,
• d) water is mechanically applied to the vehicle surface Rinse off the remaining cleaning foam and sprayed loosened dirt,
• e) the vehicle surface is machine dried.

When carrying out the method according to the invention the all time-consuming and sometimes dirty work machine executed. Only the actual washing of the vehicle is carried out manually according to method step c). Since the cleaning foam is mechanically on the drive tool surface was applied and also on the Adheres to the vehicle surface, there is sufficient moisture available so that by means of the hand-guided brush, the sponge or a washing glove, the foam only  needs to be triturated. The chemical stain remover Effect of the foam is through the brush or the like. Mecha nisch supports and thus the dirt under the greatest possible Protection of paintwork removed from the vehicle surface. There no application of cleaning during the washing process foam is required and already on the vehicle Existing cleaning foam should only be rubbed in this must be done quickly by hand and soiling of clothing is not too fear. With the new process can also be sensitive Liche motor vehicles, especially those of older design, washed and dried without the risk of There is damage or tearing of parts. Also can all recessed corners and depressions of the Vehicle surface can be cleaned better by hand than machine.

In order to accelerate the drying of the vehicle expedient after rinsing (process step d)) water, which contains a chemical drying aid, mechanically sprayed onto the vehicle surface. The drying aid Fe causes the water not to form a surface but in Form of drops is distributed on the vehicle surface and easily removed from the air flow from the blower dryer can be blown.

If the vehicle owner wishes to apply wax to the vehicle surface, this can be done in two different ways. According to a first embodiment, hot water, which contains a water-soluble wax, is mechanically applied to the vehicle surface after rinsing (process step d )).

Another method for applying wax is that after rinsing (process step d )) foam wax, consisting of a mixture of water,

Wax and air, mechanically on the vehicle surface brought.

The method according to the invention is preferably carried out in this way leads to the mechanical application of water, Reini foam, possibly wax, and drying by means of a movable portal, which against over the resting motor vehicle several times in its longitudinal direction direction is moved back and forth by motor.

The implementation of the method according to the invention is on hand explained for example with the accompanying drawing. Show it:

Fig. 1 The vehicle 1 to be washed stands in front of a portal 2 , which can be moved back and forth by motor on rails 3 relative to the vehicle. The portal has a large number of spray nozzles with which water, cleaning foam, again water, wax and the like can be sprayed onto the vehicle surface in succession. In addition, the portal 2 has a drying device, preferably a fan dryer, with corresponding air outlet nozzles.

Fig. 2 When the portal moves forward in direction A , the vehicle surface is sprayed with hot water with the addition of dirt-dissolving shampoo. Alternatively, water can be sprayed onto the vehicle surface under high pressure even in heavily soiled vehicles.

Fig. 3 With the backward movement of the portal 2 in direction B he follows through the spray nozzles attached to the portal 2, the application of cleaning foam, which partially removes the dirt from the vehicle surface and also keeps the vehicle surface moist for the subsequent cleaning.

Fig. 4 The portal 2 remains in the starting position and the vehicle 1 is cleaned by hand using a brush 4 , a sponge, a washing glove or the like. Since the cleaning foam holds the moisture and is available in sufficient quantities, the cleaning foam only needs to be rubbed onto the vehicle surface by means of the brush 4 or the like when cleaning by hand. The dirt is also loosened mechanically.

Fig. 5 When the portal 2 moves in direction A , the remaining cleaning foam and the loosened dirt are now rinsed off mechanically with high-pressure water (approx. 16 bar).

Fig. 6 When the portal 2 is moved backwards, water is sprayed on when mixed with a chemical drying aid which promotes the formation of drops. Alternatively, wax polish consisting of hot water with the addition of water-soluble wax can also be sprayed on. The wax on the one hand forms a protective film on the vehicle surface and on the other hand the wax also promotes the formation of drops. As a further alternative, foam wax consisting of water, wax and air can also be sprayed on. All of these processes are also carried out mechanically using the portal.

Fig. 7 An additional portal forward and reverse run can be switched on for the application of foam wax. In this case, only a rinse with water then takes place in the previous method step according to FIG. 6.

Fig. 8 and 9 Here the vehicle is blown off the vehicle surface by means of the blower arranged on the portal and thus the vehicle is dried during forward and reverse.

Possibly the portal 2 can also have an automatically working rim washing device with rotating brushes, which machine-clean the rims during the water spraying according to FIG. 2 or when applying foam according to FIG. 3. Underbody washing and preservation can also be done mechanically through pipes embedded in the floor with appropriate spray nozzles.
