VEHICLE WASH

The innovation relates to a vehicle wash, a method for washing a vehicle and a unit for a vehicle wash.

[0002] In vehicle washing systems, the vehicle cleaning of the surfaces of a vehicle to be washed or cleaned is essentially automated. Vehicle cleaning usually follows the rules of the so-called Sinner circle. This defines four basic parameters of cleaning, which can also be used for vehicle cleaning, namely: chemistry (e.g. cleaning medium and/or product and concentration thereof), mechanics (e.g. kinetics and/or kinematics for dissolving the dirt and making contact with the cleaning medium) , temperature and time (e.g. the chronological sequence and/or length of individual cleaning steps and/or step-by-step removal of the dirt layers at a specific frequency). These basic parameters can be varied in relation to one another in order to achieve the best possible vehicle cleaning result.

According to the basic parameter mechanics, the vehicle can be cleaned, for example, with high water pressure, in particular by using a high-pressure lance in a manual pre-cleaning or by using a large number of units in a row.

The disadvantage is that in the vehicle wash, especially during the pre-cleaning, the accessibility of certain vehicle sections such as the vehicle front, the vehicle roof and/or the vehicle rear is insufficient, which in turn has an adverse effect on the cleaning or cleaning performance of these vehicle sections. Furthermore, the use of manual means such as a high-pressure lance to clean these hard-to-reach vehicle sections is disadvantageous because they are manual and error-prone. In addition, these means require a lot of space and a complex arrangement in order to clean the hard-to-reach parts of the vehicle.

[0005] The object of the present innovation is therefore to provide a vehicle washing system which overcomes the disadvantages mentioned above. In particular, a vehicle washing system should therefore be provided that cleans the vehicle sections (vehicle front, vehicle roof, vehicle rear, etc.) that are relatively difficult to access (vehicle front, vehicle roof, vehicle rear, etc.) easily and without many structural measures (installation space, etc.) with improved results. Furthermore, such a solution should preferably be easy to integrate into existing vehicle washing systems at a later date, without having to carry out extensive structural measures.

[0006] This object is achieved by a vehicle washing system, a method for washing a vehicle and a unit having the features of the independent claims. Advantageous refinements and expedient developments of the innovation are specified in the dependent claims.

According to a first aspect of the innovation, a vehicle washing system is provided which has: a spray device which is arranged in such a way that a vehicle to be washed can be moved below the spray device relative to this in a washing direction corresponding to the longitudinal and/or travel direction of the vehicle is; a detection device, for example a contactless (optical etc.) detection device, for detecting at least one vehicle section of one or more vehicle sections of the vehicle provided along the washing direction; and a controller for controlling the spraying device based on a vehicle section detected by the detecting device. The spray device can be moved at least between a first spray position for applying a cleaning medium to the vehicle and a second spray position for applying a cleaning medium to the vehicle. The control device is set up, based on the vehicle section detected by the detection device, the spray device in a

to move the (at least two, preferably three) spray positions.

In addition to the relative movement between the vehicle and the spray device and along the washing direction - preferably by the spray device being stationary and the vehicle moving (e.g. in a car wash) or for example also by the spray device moving while the vehicle remains stationary (e.g. in a gantry car wash) or by both moving, for example - the spraying device can be moved in such a way that it can move either into the first spraying position or the second spraying position (or into the optional third or further spraying position). Depending on the at least one vehicle section detected by the detection device, the control device can consequently move the spray device between the spray positions in order to achieve cleaning of the vehicle adapted to this at least one vehicle section (e.g. vehicle front, vehicle roof and/or vehicle rear). This results in a particularly good cleaning effect. The (electronic) control device also ensures that the individual cleaning steps that can be carried out with the spray device that can be moved into the different spray positions are automated.

[0009] Consequently, a vehicle washing system is provided that can reach vehicle sections that are difficult to access or reach without complex structural measures and can clean them effectively, adapted to the respective vehicle section. And this in particular without manual operation of the spraying device being necessary. Above all, the mechanical cleaning is thus improved without having an additional expenditure of time. In addition, the spray device can be easily integrated into existing vehicle washing systems. In addition, there is the advantage that the vehicle can be cleaned better without increasing the length of the vehicle washing system, in particular a washing tunnel, in the washing direction.

In an advantageous embodiment of the innovation, the spray device can be moved into a third spray position (and preferably into further spray positions) for applying a cleaning medium to the vehicle. This has the advantage that the spray device can be adapted even better to the respective vehicle sections or vehicle contours of the vehicle. Consequently, the cleaning effect is improved.

The spray device can be arranged such that the position and/or orientation of the spray device is changed during the movement of the spray device into one of the spray positions, so that the spray device can assume a defined position and/or orientation relative to the vehicle in this spray position . This results in the advantage that, for example, a plane or spray plane of the spray device along which the cleaning medium is discharged is at a defined angle to the vehicle section to be cleaned (for example essentially 45° or 90°). The cleaning medium emitted by the spray device can thus be applied to the vehicle section to be cleaned in particular in such a way that dirt (e.g. with a desired leverage effect) is effectively removed and/or the vehicle section to be cleaned is defined by the position and/or orientation of the spray device spray direction is protected.

[0012] The spray device can be suitable or set up to apply the cleaning medium to the vehicle along a (or the previously mentioned) spray plane. That is, the spray device emits the cleaning medium along a specific spray direction, which corresponds, for example, to the axis of symmetry of the spray jet (e.g. in the form of a cone), this spray direction being parallel to the spray plane. In the first spray position, the spray plane is preferably inclined to the washing direction (inclined), particularly preferably inclined in the washing direction. The oblique orientation is advantageous, for example, when the vehicle section to be cleaned runs at an angle to the horizontal, as is the case, for example, with parts of the front of the vehicle (front/windshield, etc.) and/or the rear of the vehicle (rear window, etc.). Alternatively or additionally, in the second spray position, the spray plane is inclined (preferably inclined in or against the washing direction) or perpendicular to the washing direction. The

Vertical orientation is advantageous, for example, when the vehicle section to be cleaned runs essentially horizontally, as is the case with the vehicle roof, for example.

Alternatively or additionally, it can preferably be provided that, if present, in the third spray position, the spray plane is inclined to the washing direction (inclined), particularly preferably inclined against the washing direction. In particular, the spray level in the third spray position is then oriented differently with respect to the washing direction than in the first spray position. For example, the spray plane in the third spray position can be essentially mirror-inverted to the spray plane in the first spray position. In other words, it can be provided that the spray level in the first spray position is directed counter to the direction of travel (in order to advantageously clean parts of the front of the vehicle, for example), with the spray level being directed in the direction of travel in the second spray position (in order to advantageously clean parts of the rear of the vehicle, for example to clean). The oblique orientation in the third spray position is therefore advantageous, for example, when the vehicle section to be cleaned runs obliquely to the horizontal, as is the case in particular with parts of the rear of the vehicle (rear window, etc.).

In an advantageous embodiment, the spray device is set up to adjust the spray pressure of the cleaning medium (for example with a pump and/or with a pressure reducer provided on a pump), the control device being set up based on the vehicle section detected by the detection device Adjust the spray pressure of the spray device. This setting of the spray pressure can in particular be provided in addition to a control circuit for independent (automatic) regulation of the spray pressure. Consequently, it is advantageously achieved that a particularly good cleaning effect and/or an advantageous protection of the vehicle to be cleaned is brought about. For example, the spray pressure can be increased when the vehicle section to be cleaned is relatively far away from the spray device, as is the case, for example, with parts of the vehicle rear or the vehicle front; Due to the increased spray pressure, it is thus ensured that the cleaning medium has sufficient pressure for cleaning when it hits the vehicle for cleaning. If the vehicle section to be cleaned is relatively close to the spray device, as is the case, for example, with parts of the vehicle roof, the spray pressure can be reduced; Due to the relatively small distance between the spray device and the vehicle section, the cleaning medium that hits the vehicle for cleaning still has sufficient pressure, but not so high that it damages the vehicle section (e.g. the vehicle paintwork and/or protective layers). Consequently, the spray pressure in the second spray position can preferably be lower than the spray pressure in the first spray position and, if present, in the optional third spray position.

The vehicle washing system preferably has a support structure, with the spray device being movably mounted on the support structure in order to be movable with respect to at least one axis of movement, which corresponds in particular to a rotation or pivot axis, so that the spray device can be moved by moving with respect to the axis of movement in at least one of the spray positions is movable. In each of the spraying positions, the spraying device therefore assumes a respective position (for example position and/or orientation) relative to the supporting structure. The support structure has the particular advantage that the spray device is movably arranged without taking up a lot of space. In addition, the support structure can ensure that it can be easily provided (assembled and/or disassembled) in the vehicle washing system together with the spray device. Consequently, the supporting structure also has the advantage of simplified assembly and/or (subsequent) integration into an (existing) vehicle washing system.

The vehicle washing system preferably comprises one or more mechanical, pneumatic, electrical, magnetic and/or hydraulic components arranged to move the spray device into at least one or each of the spray positions. In particular, these components ensure that the spray device can be moved quickly and precisely into the respective position. Preferably one or more of the components

nents provided on the support structure.

[0017] The vehicle washing system can have one or more moving elements, each movable along a linear axis, which are arranged in order to move the spraying device into at least one of the spraying positions. Because the respective movement element can only be moved along the longitudinal axis, but is arranged in such a way that the spray device can be moved into at least one of the spray positions, a particularly compact arrangement is provided. For example, the one or more movement elements can each be provided in the form of a telescopic element.

The spray device is preferably set up to move back and forth in at least one or each of the spray positions relative to the vehicle, for example about an axis of rotation and/or along an axis of movement extending transversely to the washing direction. In other words, the back and forth movement takes place, for example, by a translatory and/or rotary movement. The axis of rotation runs, for example, perpendicularly to the spray plane and/or parallel or obliquely to the washing direction. Viewed from above (ie, for example, when looking perpendicularly at the vehicle roof), the axis of rotation extends, for example, longitudinally and/or parallel to the washing direction. If the spray device is moved back and forth in a translatory manner along the movement axis extending transversely to the washing direction, the movement axis runs transversely or perpendicularly to the washing direction when viewed from above.

The back-and-forth movement preferably takes place at a defined frequency, for example in the range from 0.25 to 4 Hz, preferably in the range from 0.5 to 3 Hz, particularly preferably in the range from 1 to 2 Hz; in a particularly preferred embodiment, the defined frequency is 1.4 Hz or 1.6 Hz. Consequently, the cleaning medium can be applied by means of the reciprocating spray device in the form of a sinusoidal curve to the vehicle moving relative to the spray device. The reciprocating (or pulsating) spray device has the particular advantage that effective cleaning takes place. For example, the spray device that moves back and forth covers the entire width of the vehicle running transversely to the washing direction, while the spray jet of the cleaning medium that moves back and forth has a mechanically advantageous effect on the layers of dirt to be removed.

The spray device is therefore preferably set up to move the spray jet from one side of the vehicle (e.g. the left) to the other side of the vehicle (e.g. the right) and back to the one side of the vehicle by the back-and-forth movement. The reciprocating spray jet and the vehicle moving relative to the spray device allow the spray jet to sweep or spray the vehicle according to a wave (e.g. sine wave or curve) whose direction of propagation extends from the front of the vehicle to the rear of the vehicle; the amplitude of the wave is preferably constant. The oscillation width of the shaft then preferably corresponds at least to the width of the vehicle.

The spraying device may comprise a drive unit which is arranged to drive the spraying device to preferably move back and forth at least in the corresponding spraying position. In particular, the drive unit can be functionally connected to the control device. The drive unit, for example an electric motor, offers the particular advantage that the frequency of the spray device moving back and forth can be set in a defined manner by the control device.

In an advantageous embodiment, the vehicle washing system also has a support element which receives the spray device. Thus, the spray device is accommodated compactly in the car wash. The support element preferably accommodates the spray device in such a way that the spray device can be moved back and forth relative to the support element and relative to the vehicle section detected by the detection device. For example, the support element has one or more bearings or joints that receive/receive the spray device so that it can be moved back and forth with respect to the axis of rotation and/or along the axis of movement extending transversely to the washing direction.

The support element can be at least partially in the form of a plate. The support element is thus of compact design and is also easy to produce.

It is preferred if the drive unit, which is provided to move the spray device back and forth, is arranged on the support element. The drive unit is thus arranged without taking up much space. For example, the drive unit can be arranged on an upper side, that is to say on a side of the support element which faces away from the vehicle.

The support element preferably has one or more through-openings through which one or more drive elements of the drive unit extend in order to be connected to the spray device and to move it back and forth. This has the advantage that the drive unit and spray device are arranged in a compact manner in relation to the support element. The vehicle wash system thus takes up little space. For example, a first drive element extends through a first through-opening and a second drive element through a second through-opening. The drive element or the drive elements can each be at least partially in the form of a rod.

The support element is preferably connected to the support structure in such a way that the spray device, received by the support element, is movably mounted on the support structure with respect to the axis of movement. This has the advantage of a compact arrangement of the spray device. For the purpose of moving the spray device into at least one or each of the spray positions, it is preferably provided that the support element is connected to the one or more movement elements. In other words, the at least one movement element is connected to the support structure at a first end and to the support element at a second end, so that a (linear) movement of the at least one movement element moves the support element and thus the spray device relative to the support structure, which in turn causes the Spray device is moved into one of the spray positions.

The spray device can be arranged to be movable in or along the washing direction, so that the spray device can be moved in and/or opposite to the washing direction relative to the vehicle, while the vehicle preferably remains stationary (or also in and/or opposite to the washing direction is movable). This has the advantage that the vehicle does not have to be moved in order to move the spray device relative to the vehicle and in the washing direction.

In a particularly preferred embodiment, the vehicle washing system can also have a conveyor for conveying the vehicle in the washing direction (and optionally also in the opposite direction) and relative to the spray device. Thus, the vehicle can be moved relative to the spray device in the washing direction, while the spray device preferably remains stationary. The spray device can thus be designed in a simple manner, in particular without means for moving the spray device in the washing direction and relative to the vehicle.

The spray device preferably has a plurality of spray openings for dispensing the cleaning medium. The spray device can thus deliver the cleaning medium via the multiple spray openings in such a way that the cleaning medium is applied to as large an area of the vehicle as possible. Consequently, there is the advantage, among other things, that the cleaning can be optimized in terms of time. In particular, the spray openings can be arranged such that when the spray device moves back and forth relative to the vehicle, the spray medium is applied to the vehicle according to a plurality of sinusoids which have a phase offset relative to one another in the direction of the washing direction. In this way, the cleaning medium dispensed with the spray device can be applied to a particularly large surface area of the vehicle; the vehicle is thus almost completely covered by the cleaning medium. In a particularly preferred embodiment, the spray openings are evenly distributed and/or arranged in the manner of a cross. The spray openings can be arranged, for example, in two rows crossing one another, with one of the rows particularly preferably extending transversely or perpendicularly to the washing direction and the other row extending transversely or perpendicularly to the first row or essentially to the washing direction. By arranging the spray orifices according to two rows that are transverse to each other (e.g. crossing each other), the cross arrangement of the spray orifices or another arrangement of the spray orifices, e.g

T-arrangement, be formed. For example, the spray device has at least two supply lines arranged according to a cross, for example each in the form of a tube, in or on which the spray openings are formed in order to be arranged in particular according to a cross.

The detection device, which is, for example, a contactless, preferably optical detection device, can have a camera and/or one or more light sources (for example laser light sources) and/or one or more optical sensors. For example, the detection device detects a vehicle section by measuring the height of the vehicle section to be cleaned in each case and then deciding which vehicle section (for example vehicle front, vehicle roof, vehicle rear) this height corresponds to; this corresponding vehicle section is then given to the controller as a detected vehicle section, with the controller then moving the spray device into one of the spray positions based on this detected vehicle section. Alternatively or additionally, it can be provided that the detection device detects the at least one vehicle section by image processing or image recognition.

In addition to the spray device, the vehicle washing system can also have a washing device which is arranged in such a way that the vehicle to be washed can be moved relative to it in the washing direction. The washing device can be arranged, for example, in such a way that it carries out cleaning, which takes place after or before cleaning by means of the spray device. The washing device can have, for example, one or more rotatable washing brushes and/or movable washing cloths and/or lateral washing units. The washing device can therefore in particular have means that can clean areas of the vehicle that are difficult or only partially accessible for the spray device. The washing device is preferably provided by a car wash, but can also be designed as a portal washing system (so that the vehicle washing system can be operated, for example, as a mobile system with a movable portal, as is usually the case at gas stations).

According to a second aspect of the innovation, a method for washing a vehicle with a spray device, for example as described above, is provided. The method has the following steps: moving a vehicle to be washed below a spray device and relative thereto in a washing direction corresponding to the longitudinal direction and/or the direction of travel of the vehicle; applying, with the spray device in a first spray position, a cleaning medium to the vehicle; Detection, with a detection device, of at least one vehicle section of one or more vehicle sections of the vehicle provided along the washing direction; based on the vehicle portion sensed by the sensing device, moving the spray device to a second spray position; and applying, with the spray device in the second spray position, a cleaning medium to the vehicle.

The above description of the car wash applies analogously to the method according to the innovation.

The step of detecting the at least one vehicle section can take place before or during the step in which the spray device applies the cleaning medium to the vehicle in the first spray position.

The method can further have the following steps: optionally detecting, with the detecting device, at least one further vehicle section of the vehicle; moving, based on the vehicle section (preferably the further vehicle section) detected by the detection device, the spray device to a third spray position; and applying, with the spray device in the third spray position, a cleaning medium to the vehicle. The same applies in the same way to any optional further spray positions.

The step of detecting the at least one further vehicle section can take place before or during the step in which the spray device is in the second spray position

applies the cleaning medium to the vehicle.

The method can also have the following step: setting, based on the vehicle section detected by the detection device, a spray pressure of the cleaning medium emitted by the spray device, so that the spray device sprays the cleaning medium, preferably at least in the second spray position, with a defined pressure picks up the vehicle.

It is preferred if the spray device applies the cleaning medium to the vehicle along a spray plane in each of the spray positions, with the spray plane in the first spray position being inclined to the washing direction (inclined), preferably inclined in the washing direction, and/or with the spray plane is perpendicular to the washing direction in the second spray position, and/or wherein the spray plane in the optional third spray position is inclined to the washing direction (inclined), preferably inclined against the washing direction.

The spray device can move back and forth in at least one or each of the spray positions, preferably transversely to the washing direction. As a result, the complete width of the vehicle, running transversely to the washing direction, can be covered by the spray device. The back and forth movement thus moves the spray jet from one side of the vehicle (e.g. the left) to the other side of the vehicle (e.g. the right) and back to one side of the vehicle again. The reciprocating spray jet and the vehicle moving relative to the spray device allow the spray jet to sweep or spray the vehicle according to a wave (e.g. sine wave or curve) whose direction of propagation extends from the front of the vehicle to the rear of the vehicle; the amplitude of the wave is preferably constant. The oscillation width of the shaft then preferably corresponds at least to the width of the vehicle.

According to a third aspect of the innovation, a unit for a vehicle washing system, for example for a vehicle washing system as described above, is provided. The unit has a spray device that can be arranged in such a way that a vehicle to be washed can be moved below the spray device and relative to it in a washing direction corresponding to the longitudinal direction and/or direction of travel of the vehicle. The spray device can be moved at least between a first spray position for applying a cleaning medium to the vehicle and a second spray position for applying a cleaning medium to the vehicle. The spray device is also set up to move back and forth in at least one or each of the spray positions relative to the vehicle, for example about an axis of rotation and/or along a movement axis extending transversely to the washing direction.

In addition to the relative movement between the vehicle and the spray device and along the washing direction - preferably by the spray device being stationary and the vehicle moving or, for example, by the spray device moving while the vehicle remains stationary or by, for example, both moving as well the spraying device is movable in such a way that it can move selectively into the first spraying position or the second spraying position (or into the optional third spraying position). Depending on the at least one vehicle section detected by the detection device, the control device can consequently move the spray device between the spray positions in order to achieve cleaning of the vehicle adapted to this at least one vehicle section (e.g. vehicle front, vehicle roof and/or vehicle rear). This results in a particularly good cleaning effect.

Consequently, a unit, ie in particular a vehicle washing system unit, is provided that can reach vehicle sections that are difficult to access or reach without complex structural measures and can clean them effectively in each case, adapted to the respective vehicle section. And this in particular without manual operation of the spraying device being necessary. Above all, the mechanical cleaning is thus improved without having an additional expenditure of time. In addition, the spray device can be easily integrated into existing car wash systems. There is also the advantage that the vehicle

can be cleaned better without increasing the length of the car wash in which the unit is to be used in the washing direction. The spray device of the unit can likewise have all the features of the spray device described above or form the unit itself in this way.

The axis of rotation is, for example, perpendicular to a spray plane (as described above) of the spray device and/or perpendicular or oblique to the washing direction. The axis of rotation preferably runs transversely or perpendicularly to a movement axis via which the spray device can be moved between the at least two spray positions. If the back and forth movement takes place via a translational movement axis, this preferably runs along or parallel to the movement axis, via which the spray device can be moved between the at least two spray positions. The to-and-fro movement preferably takes place at a defined frequency, for example in the range from 0.25 to 4 Hz, preferably in the range from 0.5 to 3 Hz, particularly preferably in the range from 1 to 2 Hz; In a particularly preferred embodiment, the defined frequency is 1.4 Hz or 1.6 Hz. The reciprocating (or pulsating) spray device also has the advantage that effective cleaning takes place. For example, the entire vehicle width running transversely to the washing direction can be covered by the spray device, while the reciprocating spray jet of the cleaning medium has a mechanically advantageous effect on the layers of dirt to be removed.

The spray device is therefore preferably set up to move the spray jet from one side of the vehicle (e.g. the left) to the other side of the vehicle (e.g. the right) and back to the one side of the vehicle by the back-and-forth movement. The reciprocating spray jet and the vehicle moving relative to the spray device allow the spray jet to sweep or spray the vehicle according to a wave (e.g. sine wave or curve) whose direction of propagation extends from the front of the vehicle to the rear of the vehicle; the amplitude of the wave is preferably constant. The oscillation width of the shaft then preferably corresponds at least to the width of the vehicle.

The spraying device can preferably be moved into a third spraying position and preferably also into further spraying positions for applying a cleaning medium to the vehicle. This has the advantage that the spray device can be adapted even better to the contour of the vehicle in order to clean it.

The spray device can be movably arranged in such a way that the position and/or orientation of the spray device is changed during the movement of the spray device into one of the spray positions, so that the spray device has a defined position and/or orientation relative to the vehicle or the washing direction. This results in the advantage that, for example, the spray plane of the spray device, along which the cleaning medium is dispensed, can be brought at a defined angle to the vehicle or the vehicle section to be cleaned (for example 45° or 90°). The cleaning medium emitted by the spray device can thus be applied to the vehicle section to be cleaned in particular in such a way that dirt is effectively removed, for example with a desired leverage effect, and/or the vehicle section to be cleaned (in particular the paintwork and/or protective layers, etc.) is spared.

The spray device can be set up to adjust the spray pressure of the cleaning medium; this preferably depending on the spray position. Consequently, it is advantageously achieved that a particularly good cleaning effect and/or an advantageous protection of the vehicle to be cleaned is brought about. For example, the spray pressure can be increased when the vehicle section to be cleaned is relatively far away from the spray device, as is the case, for example, with parts of the vehicle rear or the vehicle front; Due to the increased spray pressure, it is thus ensured that the cleaning medium has sufficient pressure when it hits the vehicle for cleaning. Is the vehicle to be cleaned

section relatively close to the spray device, as is the case, for example, with parts of the vehicle roof, the spray pressure can be reduced; Due to the relatively small distance between the spray device and the vehicle section, the cleaning medium that hits the vehicle for cleaning still has sufficient pressure, which in particular is not so high that it damages the vehicle section (e.g. the vehicle roof).

The unit can also have a support structure, with the spray device being movably mounted on the support structure in order to be movable with respect to at least one axis of movement, which corresponds in particular to a rotation or pivot axis, so that the spray device can be moved by moving with respect to the axis of movement in at least one or each of the spray positions is movable. In each of the spraying positions, the spraying device therefore assumes a respective position (for example position and/or orientation) relative to the supporting structure. The support structure has the particular advantage that the spray device is movably arranged without taking up a lot of space. In addition, the support structure can have the effect that the unit can be easily provided (assembled and/or disassembled) in a vehicle washing system. Consequently, the support structure also has the advantage of simplified assembly and/or subsequent integration of the assembly into an (existing) vehicle washing system.

The unit may further include one or more mechanical, pneumatic, electrical, magnetic and/or hydraulic components arranged to move the spray device into at least one of the spray positions. In particular, these components ensure that the spray device can be moved quickly and precisely into the respective position. One or more of the components are preferably provided on the support structure.

The unit can also have one or more movement elements that can be moved along a linear axis and are arranged to move the spray device into at least one of the spray positions, with the one or more movement elements preferably being provided in the form of a telescopic element/ 'are. Because the respective movement element can only be moved along the linear axis or longitudinal axis, but is arranged in such a way that the spray device can be moved into at least one of the spray positions, a particularly compact arrangement is provided. For example, the one or more movement elements can each be provided in the form of a telescopic element.

[0051] The unit can also have a support element which accommodates the spray device. The spray device is thus accommodated in the unit in a compact manner. The support element preferably accommodates the spray device in such a way that the spray device can be moved back and forth relative to the support element and relative to the vehicle or vehicle section to be cleaned. For example, the support element has one or more bearings or joints, which receive/receive the spray device, so that they can be moved back and forth with respect to the axis of rotation and/or along the axis of movement extending transversely to the washing direction.

The support element is preferably connected to the support structure in such a way that the spray device is movably mounted on the support structure with respect to the movement axis. This has the advantage of a compact arrangement of the spray device.

For the purpose of moving the spray device into at least one or each of the spray positions, it is preferably provided that the support element is connected to the one or more movement elements. In other words, the at least one movement element is connected to the support structure at a first end and to the support element at a second end, so that a (linear) movement of the at least one movement element moves the support element and thus the spray device relative to the support structure, which in turn causes the Spray device is moved into one of the spray positions.

The support element is preferably at least partially in the form of a plate. The support element is thus of compact design and is also easy to produce.

The aggregate may further comprise a drive unit arranged to drive the spray device to move back and forth. In particular, the drive unit can be functionally connectable to a control device. The drive unit, for example an electric motor, thus offers the advantage that the frequency of the spray device moving back and forth can be set in a defined manner.

The drive unit is preferably arranged on the support element. The drive unit is thus arranged without taking up much space. For example, the drive unit can be arranged on an upper side, that is to say on a side of the support element which faces away from the vehicle.

The support element preferably has one or more through openings through which one or more drive elements of the drive unit extend in order to be connected to the spray device and to move it back and forth. This has the advantage that the drive unit and spray device are arranged in a compact manner in relation to the support element. The unit therefore takes up little space. For example, a first drive element extends through a first through-opening and a second drive element through a second through-opening. The drive element or the drive elements can each be at least partially in the form of a rod.

[0058] The spray device can have a plurality of spray openings for dispensing the cleaning medium. The spray device can thus deliver the cleaning medium via the plurality of spray openings in such a way that the cleaning medium is applied to the largest possible area of the vehicle. Consequently, there is the advantage that cleaning with the unit can be optimized in terms of time. In a particularly preferred embodiment, the spray openings are evenly distributed and/or arranged in the manner of a cross. The spray openings can be arranged, for example, in two intersecting rows, one of the rows particularly preferably extending transversely or perpendicularly to the washing direction and the other row transversely or perpendicularly to the first row or essentially to the washing direction. By arranging the spray openings according to two rows which are transverse to each other (and eg cross one another), the cross arrangement of the spray openings or another arrangement of the spray openings, for example a T-arrangement, can be formed. For example, the spray device has at least two supply lines arranged in a cross, for example each in the form of a tube, in or on which the spray openings are formed, so that they are arranged in a cross, for example.

Figures 1 and 6 show a schematic view of a preferred embodiment of a vehicle wash 1. The vehicle wash 1 has a spray device 2, which is arranged such that a vehicle to be washed 3 below the spray device 2 and relative to this in one of the Longitudinal and / or direction of travel of the vehicle 3 corresponding washing direction L is movable; the longitudinal direction of the vehicle 3 can be directed in or against the direction of travel. In FIGS. 1 and 6, the washing direction L runs from right to left. The vehicle 3 can consist of one or more vehicle sections provided along the washing direction L. These vehicle sections include, for example, the front of the vehicle (in particular with the windscreen), the vehicle roof and/or the rear of the vehicle (in particular with the rear window and/or comprising a trunk). For example, the spray device 2 is arranged to be movable, in particular along, i.e. in and/or opposite to, the washing direction L, so that the spray device 2 can be moved along (i.e. in or opposite) to the washing direction L relative to the vehicle 3, while the vehicle 3 preferably remains stationary. In a preferred embodiment, however, it is provided that the vehicle washing system 1 has a conveyor device, not shown in detail, which is arranged to move the vehicle 3 in the washing direction L (and possibly also in the opposite direction) and relative to the spray device 2; the vehicle wash system 1 is then preferably designed as a car wash. The spray device 2 can then remain stationary.

The spraying device 2 can be moved at least between a first spraying position for applying a cleaning medium to the vehicle 3 and a second spraying position for applying a cleaning medium to the vehicle 3 . The first spray position is shown by way of example in FIGS. 1 to 5, and the second spray position is shown by way of example in FIGS. In a preferred embodiment, the spraying device 2 can be moved into a third spraying position (e.g. mirror-inverted to the first spraying position with respect to a vertical mirror plane perpendicular to the plane of the drawing), in which a cleaning medium can be applied to the vehicle 3 . If required, the spray device 2 can preferably also be set up in such a way that it can be moved into further spray positions. The cleaning medium used in the spray positions has, in particular, water or consists of water; according to the latter alternative, the cleaning with the spray device 2 can then be carried out exclusively with water. The cleaning medium can have a cleaning agent (for example a chemical cleaning agent provided in addition to the water), so that the cleaning medium results in (white) washing foam, for example.

The spray device 2 can be movably arranged such that during the movement of the spray device 2 in one of the spray positions, the position and / or orientation of the

Spraying device 2 is changed. If the spraying device 2 has arrived in this (desired) spraying position, then in this spraying position it assumes a defined position and/or orientation relative to the vehicle 3 or at least one vehicle section. As can be seen by way of example in FIG. 1, this spraying position can correspond to the first spraying position, which is preferably an initial position. In this spray position, the spray device 2 can assume such a defined orientation relative to the vehicle 3 that a spray plane 21, which is stationary or fixed with respect to the spray device 2, runs obliquely to the washing direction L and/or to the vertical, for example at an angle in Range from 40° to 50°, in particular 45°. The spray plane 21 can then run essentially perpendicularly to a vehicle section of the vehicle 3 that runs at least partially obliquely to the horizontal, for example to the windscreen, so that the spray device 2 applies the spray medium essentially perpendicularly to this vehicle section.

The (desired) spray position into which the spray device is moved in order to assume a defined position and/or orientation relative to the vehicle can also be the spray position shown as an example in FIG. As can be seen from FIG. The spray plane 21 can then run essentially perpendicular to a vehicle section of the vehicle 3 which at least partially runs essentially parallel to the horizontal, ie for example to the vehicle roof. By moving the spray device 2 from the first spray position to the second spray position, it is thus advantageously achieved that the spray device assumes a different relative position and/or orientation, in particular to the vehicle 3 or the washing direction L, for a different vehicle section.

The spray device 2 can be moved into at least one or each of the spray positions, preferably by pivoting. In particular, it can be provided that the vehicle washing system 1 has a support structure 30, as shown by way of example in FIGS. 1 to 9, on which the spray device 2 is movably mounted in order to be moved between the at least two and preferably three spray positions. The support structure 30 can be seen particularly well in FIG. As can be seen from this figure, the spray device 2 can be movably mounted directly or indirectly on the support structure 30 in such a way that the spray device 2 is movably mounted with respect to at least one movement axis, which in the embodiment shown here is advantageously a rotary or pivot axis. The movement axis is provided at least partially by the support structure 30 , for example by having one or more bearing or joint areas 31 . By moving or pivoting the spray device 2 with respect to the movement axis, the spray device 2 can thus be moved into at least one or each of the spray positions, ie for example from the spray position shown in FIG. 1 to the spray position shown in FIG.

As can be seen in FIG. 9, one or more movement elements 32, each movable along a linear axis, can be provided in order to move the spray device 2 between the respective spray positions. The movement elements 32 are each arranged in such a way that the spray device 2 can be moved between the spray positions by moving the movement elements 32 along the respective linear axis. As shown in FIG. 9, for example, a shortening or contraction of one or more of the movement elements 32 can cause the spraying device 2 to be pivoted (in FIG. 9: upwards), for example to the first spraying position, as shown for example in FIG. to get. It is preferred if the movement elements 32 are each connected (articulated) with one of their ends to the support structure 30, in particular a cross member 33, while the other end is connected directly or indirectly to the spray device 2 (articulated). The traverse 33 can, for example, be part of a U-shaped frame part of the support structure 30 that preferably extends along the vertical. The movement elements 32 can each be provided in the form of a telescopic element. Furthermore, one or more mechanical, pneumatic, electrical, magnetic and/or hydraulic components (not shown) can be provided.

be seen, which are arranged to move the spray device 2 in at least one or each of the spray positions. These components can therefore be arranged in particular in such a way that they interact with one or more of the movement elements 32 in order to move them along the respective linear axis.

The preferred embodiment of the spray device 2 shown in the figures is also suitable and/or set up to move back and forth in at least one or each of the spray positions relative to the vehicle 3 or a vehicle section. In the preferred embodiment shown, this back-and-forth movement takes place about an axis of rotation R. In this embodiment, the axis of rotation R is preferably perpendicular to the spray plane 21 in order, for example, to improve or generate spray delivery in the spray plane 21 . As can be seen in particular in Figure 9, a support element 40 - for example at least partially in the form of a plate - can be provided, which accommodates the spray device 2, in particular in such a way that the spray device 2 can be moved relative to the support element 40 and thus relative to the vehicle 3 or .Vehicle section is reciprocally movable. For example, the support element 40 has one or more bearing areas or joint areas 41 which define the axis of rotation R. Correspondingly, the spray device 2 may have one or more articulation areas 22 which are articulated to the articulation areas 41 to form one or more articulations and to cause the spray device 2 to be movable back and forth about the axis of rotation R.

As shown in FIG. 9 and particularly well recognizable in the section according to FIG. 3, a drive unit 50 can also be provided, which is arranged to drive the spray device 2 so that it preferably moves back and forth at least in the corresponding spray position. The drive unit 50 can be, for example, a rotary drive unit and/or an electric drive unit or an electric motor. In particular, the drive unit 50 can have one or more drive elements 51 which are connected to the spray device 2 in order to move it back and forth in accordance with the movement of the drive unit 50 . The drive elements 51 can be provided, for example, in each case partially in the form of a rod. As can be seen in particular from FIG. 10, the spray device 2 can have a connection area 23 which is designed to be connected in an articulated manner to a respective end of each of the drive elements 51 . The storage area 23 can be at least partially plate-shaped, for example in such a way that the drive elements 51 are provided with their respective ends between two plate areas of the storage area 23 and are connected to them in an articulated manner.

The drive unit 50 can be arranged on the support element 40 . For this purpose, the support element 40 can have a corresponding fastening area for the drive unit 50 . For example, the drive unit 50 is provided on an upper side of the support element 40, the upper side facing away from an underside of the support element 40 and/or the vehicle 3 located under the spray device 2. The underside of the support element 40 is, for example, that side on which the spray device 2 and/or the joint areas 41 are provided. As can be seen in particular from FIG. 9, the support element 40 can have one or more, in particular two, through openings 42 through which the drive elements 51 extend in order to be connected to the spray device 2 and to move it back and forth.

It can also be seen in FIG. 9 that the support element 40 can be connected to the support structure 30 in such a way that the spray device 2, received by the support element 40, is attached to the support structure 30 with respect to the movement axis for moving the spray device 2 is movably mounted between the at least two spray positions. For example, the support element 40 can have one or more bearing or joint areas 43 which are connected in an articulated manner to the one or more joint areas 31 of the support structure 30 . The support element 40 can thus be moved in an articulated manner on the support structure 30 and with respect to the axis of movement defined by the joint regions 31 in order to move the spray device 2 between the spray positions. According to such an embodiment, the movement elements 32 can be indirectly connected to the spray device 2, namely via the carrying element

ment 40. The movement elements 32 thus each have an end which is connected in an articulated manner to the support element 40 or to the bearing area 44 arranged on it. Thus, upon movement of one or more of the movement elements 32 - for example shortening or contraction - the support element 40 and thus also the spray device 2 upwards, for example in the direction of the traverse 33, pivoted. The spray device 2 is thus moved into one of the spray positions, such as the first spray position.

In the figures 10 to 13 an embodiment of a spray device 2 is shown. As can be seen from these figures, the spray device 2 can have a plurality of spray openings 24, for example each as part of a respective spray nozzle. The spray openings 24 are suitable or adapted to deliver the cleaning medium in a defined manner, for example along the spray plane 21. The spray openings 24 can be arranged according to a cross, but can also be arranged according to any other shape. As can be seen by way of example in FIG. 10, the spray openings 24 can preferably be arranged in two intersecting rows, with one of the rows preferably being transverse or perpendicular to the washing direction L and the other row being transverse or perpendicular to the first row and preferably substantially transverse or perpendicular extends to the washing direction L. As can also be seen in FIG. 10, the spray device 2 can have one or more supply lines 25, for example each in the form of a tube, in which the spray openings 24 are formed. The supply lines 25 can be arranged, for example, like a cross relative to one another, so that in particular the spray openings 24 are arranged like a cross. The spray device 2 can have a (preferably single) inlet for the cleaning medium, via which the spray device 2 and preferably each of the spray openings 24 can be supplied with the cleaning medium. The spray nozzles, which have the spray openings 24, can be formed in one piece with the supply lines 25 and/or can be fastened to the supply lines 25 in a positive and/or non-positive manner, for example by means of a screw connection.

The spray device 2 is preferably connected to a flow device, for example a pump, or has this, so that the spray device 2 can apply the cleaning medium to the vehicle 3 with the aid of the flow device. In particular, the spray device 2 can be set up to adjust the spray pressure of the cleaning medium so that the cleaning medium can hit the vehicle 3 with a sufficient or defined pressure. The spray pressure in the second spray position can preferably be lower than the spray pressure in the first spray position and, if present, also than that in the optional third spray position. For example, the spray device 2 can adjust the spray pressure of the cleaning medium with the aid of the flow device and/or a pressure reducer. The flow device can be part of the spray device 2 and/or the vehicle washing system 1 .

In the figures 14 to 17, the preferred embodiment of the support structure 30 is shown. In these figures, in particular the spray device 2, the support element 40 and the movement elements 32 are not shown for the sake of clarity. As can be seen from these figures, the support structure 30 can be generally frame-shaped or designed as a frame. In particular, the support structure 30 can have different areas for attaching different components. For example, the support structure 30 can have a fastening area and/or a housing 34 on and/or in which components such as electrics and/or electronics and/or the control device described in more detail below can be provided. The supporting structure 30 can be designed in such a way that it only consists of profile elements, angle elements and/or beam elements.

In addition to the spray device 2, the vehicle washing system 1 can also have a washing device that is not shown in detail. The washing device is then arranged in such a way that the vehicle 3 can be moved relative to it, preferably by the washing device remaining stationary and the vehicle 3 moving or, for example, by the vehicle 3 remaining stationary and the washing device moving. The washing device can in particular have one or more rotatable washing brushes and/or movable washing cloths and/or lateral

have washing units. Alternatively or additionally, the washing device can be designed as a gantry system (in particular a “washing gantry”). However, it is particularly preferred if a washing line provides the washing device.

As shown schematically in FIGS. 1 and 6, the vehicle washing system 1 also has an (at least partially electrical) detection device 4 . The detection device 4 is suitable for detecting at least one vehicle section of the one or more vehicle sections of the vehicle 3 provided along the washing direction L. The detection of a vehicle section by means of the detection device 4 preferably takes place without contact, ie without mechanical contact with the vehicle 3. The detection device 4 can be an optical detection device, for example. In particular, the detection device 4 can have a camera and/or one or more laser light sources and/or one or more optical sensors. For example, at least two of these components can interact in such a way that they cover a vehicle section. For example, the detection device 4 can be set up to measure at least a respective height or a respective height range for each vehicle section. In other words, the detection device 4 can be set up to detect a height profile along the one or more vehicle sections of the vehicle 3 , ie in particular to carry out a contour measurement of the vehicle 3 .

As also shown schematically in FIGS. 1 and 6, the vehicle washing system 1 also has a control device 5 for controlling the spray device 2 on the basis of a vehicle section detected by the detection device 4 . The control device 5 is functionally connected to at least the spray device 2 (and for example to the at least one movement element 32 and/or the drive unit 50) on the one hand and to the detection device 4 on the other hand. The control device 5 is an electronic control device, which in particular has an electrical storage unit and/or a printed circuit board. The control device 5 is set up, based on the vehicle section detected by the detection device 4, to move the spray device 5 into one of the spray positions described above, i.e. for example from the position shown in Figure 1 to the spray position of the spray device shown in Figure 6, or vice versa . This will be explained below using an exemplary washing process.

First, the detection device 4 carries out a contour measurement of the vehicle 3 and consequently detects one or more vehicle sections of the vehicle 3. The detection device thus detects, for example, how the height of the vehicle 3 runs along its longitudinal direction or travel direction L. For example, a first height range corresponds to the front area (for example including the windshield), a second height range to the roof area and a third height range to the rear area (for example including the rear window). In a next step, the vehicle 3 to be washed is moved in the washing direction L relative to the spray device 2, while the preferably stationary spray device 2 is in a starting position that corresponds to the (first) spray position shown in FIG. In this spray position, the spray device 2 applies a cleaning medium, for example water, to the vehicle 3 . The spray device 2 can move back and forth so that the entire width of the vehicle is covered by the cleaning medium. The spray device 2 remains in the first spray position until the control device 5, based on the at least one vehicle section detected by the detection device 4, decides to move the spray device 2 into another or the second spray position.

In the exemplary embodiment, this is preferably done as follows. A detection device 6 is provided to measure the height of the part of the vehicle 3 driving past the detection device 6 and to send this height as a signal to the control device 5 . For example, the detection device 6 includes a light barrier system, so that the height is measured by interrupting a light barrier generated by the light barrier system at a specific height of the vehicle 3, for example from a roof edge. The control device 5 then checks whether the height indicated by the signal continues

lies in the height range of the front area detected by the detection device 4 . If so, the control device 5 refrains from moving the spray device 2 to another spray position; the spray device 2 then continues to apply the cleaning medium to the vehicle 3 in the first spray position. However, if the height specified by the signal is in another height range detected by the detection device 4, for example in that of the roof area, the control device 5 decides to move the spray device 2 into the second spray position, as shown in FIG. The spray device 2 now applies the cleaning medium in the second spray position to the vehicle 3 or at least to its roof area.

In an analogous manner, the spray device 2 can be moved into the third spray position. This means that the control device 5 then checks whether the height specified by the detection device 6 by means of the signal is still in the height range of the roof area detected by the detection device 4 . If so, the controller 5 refrains from moving the spray device to another spray position; the spray device 2 then continues to apply the cleaning medium to the vehicle 3 in the second spray position. However, if the height specified by the signal is in a different height range detected by detection device 4, for example in that of the rear area, control device 5 decides spray device 2 to the third spray position, which, for example, is mirror-inverted with respect to the vertical to the first shown in Figure 1 Spray position is to move. The spray device 2 now applies the cleaning medium in the third spray position to the vehicle 3 or at least to its rear area.

The innovation is not limited to the exemplary embodiments shown. All features described above or features shown in the figures can be advantageously combined with one another as desired within the scope of the innovation.
