Description

[0001] The invention relates to a device for cleaning two-wheeled vehicles, in particular bicycles and / or electric bicycles, and a method for cleaning two-wheeled vehicles, in particular bicycles and / or electric bicycles, according to the preambles of the independent claims.

[0002] A device with the features of the preamble of claim 1 is known from CN 207208020 U. Further devices and methods of the type in question are known from the prior art, for example from FR 2 976 539 A1, DE 43 25 973 C1, WO 2017 / 114765 A1, US 2009 / 217955 A1, WO 86 / 06693 A1 and WO 2020 / 007539.

[0003] Such devices for cleaning two-wheeled vehicles include a wet cleaning system for cleaning the vehicle using a cleaning fluid. The cleaning fluid is typically water, which may contain additives to create or enhance the cleaning effect, such as surfactants. Furthermore, devices of this type have a splash guard housing to contain the cleaning fluid. During cleaning, the two-wheeled vehicle is typically, at least partially, enclosed in the splash guard housing. Corresponding methods for cleaning two-wheeled vehicles provide for the two-wheeled vehicle to be cleaned with the cleaning fluid during the cleaning cycle.

[0004] However, devices of this type still have some disadvantages. When the bicycle is removed from the device after cleaning, it is still covered in water and soap. If it dries outside the device, it picks up dirt. The chain must also be dried before it can be used, as it is difficult to apply lubricant to a wet chain. Devices of this type are often used in bicycle repair shops. There, the bicycles are usually cleaned before repairs. In this case, it is certainly advantageous if the bicycles are dry at the start of the repair.

[0005] Handling the bicycle, especially when inserting it into or removing it from the device, carries the risk of soiling clothing, either with cleaning fluid still adhering to the bicycle or with dirt that was present before cleaning. This is particularly true for e-bikes, which have a significant weight. To transfer the force required to insert or remove the bicycle, it is typically necessary to position the body close to the bicycle, as the necessary force cannot be applied with outstretched arms.The risk of clothing becoming soiled increases significantly due to the body's positioning close to the bicycle, which is regularly necessary to exert the required forces. Even after cleaning, any liquid adhering to the bicycle poses a risk to clothing.

[0006] The invention is therefore based on the objective of demonstrating a device and a method for cleaning two-wheeled vehicles in which the aforementioned disadvantages do not occur or at least occur to a reduced extent.

[0007] The problem is solved by a method and a device having the features of the independent claims. The features of the dependent claims relate to advantageous embodiments.

[0008] According to one embodiment of the present invention, the device includes a drying unit arranged within the splash guard housing for drying the two-wheeler. It has been shown in connection with the present invention that efficient drying of the two-wheeler is possible by means of drying units arranged within the splash guard housing. It has also been shown in connection with the present invention that such an arrangement of the drying unit is possible and even advantageous despite the potentially problematic aspects, such as the risk of overheating and moisture within the splash guard housing, particularly since it allows for a compact design of the system.

[0009] According to the invention, the device is designed such that the airflow is directed at an angle of at most 80° to the longitudinal direction of a two-wheeler accommodated in the device.

[0010] Accordingly, the method for cleaning the two-wheeler can provide that the two-wheeler is dried during a drying cycle by means of an airflow generated within the splash guard housing. The device can, in particular, include a control unit configured to control the device in such a way that the different cycles of the method are carried out sequentially. The device can include operating elements for the device, which are integrated into a handle of the device.

[0011] The drying device and drying cycle significantly reduce the amount of residual liquid adhering to the bicycle. This reduces both the risk of the surrounding area being contaminated by liquid remaining on the bicycle and the risk of clothing being soiled by liquid adhering to the bicycle.

[0012] The device may, in particular, include a rotating brush for cleaning the two-wheeler. The rotating brush and / or the drying device may be movable along the two-wheeler. This movement may be in a horizontal and / or vertical direction. The drying device and the rotating brush may be arranged on a common support and move together with it. Alternatively and / or additionally, it is also conceivable that the drying device and the rotating brush may be moved independently of each other. Likewise, multiple common supports for the drying device and the rotating brush may be present. In particular, two supports of the type in question may be present, with one support arranged on each side of a two-wheeler accommodated in the device. It is understood that the device may include multiple rotating brushes.

[0013] Particularly since the device has multiple drying units, the total volume flow rate conveyed by all drying units can be at least 10 m³ / h, at least 50 m³ / h, and / or at most 500 m³ / h. Such a total volume flow rate has proven suitable for drying a two-wheeler.

[0014] The drying device is a device for drying the two-wheeler using an airflow. In this case, the drying device may include a heating element to heat the airflow. Heating increases the air's capacity to absorb liquid.

[0015] The drying device may include a radial blower. The radial blower may, in particular, be a low-pressure radial blower. A radial blower, or radial fan, is understood to be a fan that draws in air axially (parallel to the axis of rotation of the impeller) and then expels it radially at a 90° angle. The device is specifically designed to operate the radial blower at a speed of at least 1000, preferably at least 2000, and / or at most 5000 revolutions per minute. The electrical power consumption of a radial blower used in the device is, in particular, at least 250 W, preferably at least 400 W, and / or at most 1000 W.It has been shown that radial fans operated with these parameters offer a sensible balance between drying performance and heat generation, thus ensuring manageability of drying units located within the injection mold housing. Alternatively and / or additionally, other types of low-pressure blowers are also possible.

[0016] Alternatively and / or additionally, the drying system can include a side channel blower. The side channel blower can, in particular, be a medium-pressure side channel blower. Other medium-pressure blowers are also possible as an alternative and / or additional option.

[0017] Alternatively and / or additionally, the drying system may include a compressor. This compressor may be, in particular, a high-pressure compressor. Alternatively and / or additionally, other high-pressure generating devices are also possible.

[0018] The drying device, particularly if it includes a medium-pressure compressor and / or a high-pressure compressor, may incorporate an air blade. An air blade (also known as an air knife, air sword, air brush, or air scraper) is a device, especially one with a nozzle having a slotted cross-section, that generates a flat jet of air. Alternatively and / or additionally, other nozzles may be used, particularly in conjunction with a high-pressure compressor. The device may be designed such that the nozzles can be used both to generate the airflow for the drying device and to apply liquid to the two-wheeler.

[0019] The splash guard housing can be designed, in particular, to only partially accommodate the two-wheeler. Devices of the type in question can be made comparatively compact and space-saving if the device, especially the injection-molded housing, is designed to only partially accommodate the two-wheeler. This significantly reduces the overall height of the device. In particular, the device or the injection-molded housing can be designed such that the handlebars and / or the saddle protrude from the top of the injection-molded housing through an opening when the two-wheeler is inside the device. While this excludes the saddle and / or handlebars from cleaning, in practice it has been shown that the handlebars and / or saddle are typically not among the most heavily soiled areas of a two-wheeler. Furthermore, due to the materials used there (e.g., leather) or...Due to the presence of installed technical components, such as brake and shift lever units, intensive wet cleaning of these areas is often not desirable anyway.

[0020] The splash guard housing can have splash guard elements on its upper surface. These can be implemented, in particular, as brushes whose bristles move towards the bicycle passing through the opening, thus coming into contact with it and forming a splash guard. Such bristles have been used in the past on hinged elements. However, it has been shown that when such bristles are folded back after cleaning the bicycle, they typically point towards the operator of the device and can come into contact with them or their clothing, potentially soiling it, as cleaning fluid typically still adheres to the bristles.This can be counteracted if the splash guard elements can be moved towards the bicycle, which is partially enclosed within the splash guard housing, via the opening in the top of the housing, guided by a rail system. With such a guided movement via the rail system, the bristles are always directed towards the bicycle and thus away from the operator. This minimizes the risk of the operator and / or their clothing becoming soiled. The rail system can be, in particular, a telescopic rail system. Telescopic rails allow for a comparatively large range of motion while being retractable to a relatively short overall length.

[0021] The device may, in particular, include a support device for assisting the front wheel of a two-wheeled vehicle mounted in the device. The support device may be height-adjustable relative to the top of the device such that the relative position of the handlebars of the two-wheeled vehicle to the top of the device can be adjusted vertically by adjusting the height of the support device.

[0022] Especially when the handlebars of a bicycle only partially enclosed in the device are positioned outside the splash guard housing, a height-adjustable support device can optimize the cleaning effect by ensuring the bicycle protrudes from the device only as far as necessary due to the handlebars. This can vary significantly due to the different designs of various bicycles and the resulting variations in handlebar height, particularly depending on wheel size. For example, a racing bike, with its typically drop handlebars, may require a specific adjustment.

[0023] The height-adjustable support device can be implemented, in particular, by one or more threaded rods. Specifically, threaded rods can be arranged on both sides of the two-wheeler held in the device. The threaded rods can be coupled to each other with respect to their rotational movement, for example, by a suitable tensioning device. By rotating the threaded rods, which can be done manually or by means of an electric drive, the support device connected to the threaded rods can be raised or lowered.

[0024] The support device may, in particular, integrate a wheel rotation unit for turning the front wheel. The device may also include a further wheel rotation unit for turning the rear wheel. The wheel rotation units for turning the rear and / or front wheel may be coupled via a common drive and / or be independently driveable.

[0025] The device can be designed such that the airflow is directed at an angle of at least 30° to the longitudinal direction of a two-wheeler accommodated in the device. This applies in particular to the arrangement of the drying device within the device.

[0026] It has been shown that this type of airflow direction relative to the two-wheeler leads to particularly efficient drying of the two-wheeler. In particular, the available installation space in the device is used efficiently.

[0027] The drying device can be arranged, in particular, laterally and / or below a two-wheeler mounted in the device.

[0028] The drying units are arranged on both sides of a two-wheeler mounted in the device. It has been shown that drying units arranged in this way have the advantage that the airflows from the drying units, after passing through the two-wheeler, can still exert a cooling effect on the drying units on the opposite side. This contributes significantly to achieving sufficient drying performance within the splash guard housing.

[0029] In particular, the drying devices arranged on both sides of a two-wheeler mounted in the device are spaced at least 450 mm and / or at most 650 mm apart from the drying device located on the opposite side of the two-wheeler. If the drying devices are movable along the two-wheeler, the aforementioned distance is understood to be the smallest distance that can be achieved by moving the drying devices.

[0030] If the drying devices are movable along the two-wheeler, the device is designed in particular to effect the movement, especially to control it, so that the drying devices on both sides of the two-wheeler are opposite each other and are moved synchronously along the two-wheeler.

[0031] The drying devices are specifically oriented such that the drying devices located opposite each other on either side of the two-wheeler are not directly facing each other. Preferably, the drying devices are oriented at an angle of less than 80° to the longitudinal direction of a two-wheeler mounted in the device, such that the airflow generated by one drying device is directed not directly at an opposing drying device, but rather at an opposing rotatable brush. With this orientation, the opposing drying devices still benefit from the cooling effect of the airflow, but direct moisture ingress into the opposing drying devices due to liquid carried along in the airflow from the two-wheeler is thereby avoided.

[0032] It is particularly advantageous if the drying equipment has a protection rating of at least IP 66. Using drying equipment of this protection class is beneficial to protect the electrical components of the drying equipment from the liquid inside the splash-proof housing.

[0033] The drying devices, which are primarily radial blowers, can be designed and arranged such that the air they convey is drawn in from below. This has the advantage that the introduction of liquid into the drying devices with the drawn-in air is lower than if the air were drawn in from other directions. This particularly protects the motor of the respective drying device, as the risk of liquid penetrating the motor housing along the shaft is reduced.

[0034] The drying devices, which are in particular radial blowers, can be designed and arranged such that the motor of the respective drying device is located above the air-conveying area of ​​the drying device. Such an arrangement is also advantageous with regard to the possible ingress of moisture from the occupational exposure area of ​​the drying device into the motor of the drying device.

[0035] The device should be designed such that drying units are arranged at a lower height than the outlet nozzles for cleaning fluid and / or rinsing fluid. This allows for a compact arrangement within the splash guard housing. At the same time, thorough cleaning and drying can be ensured, with the cleaning fluid reaching even the highest areas of the motorcycle. It has been shown that the operation of electric drying units within the splash guard housing is possible despite their arrangement at a lower height than the corresponding outlet nozzles.

[0036] Drying units can be arranged one above the other. Stacked drying units offer the advantage of allowing the entire height of the bicycle to be dried.

[0037] At least one drying device, and in particular four drying devices, can be arranged such that the airflow generated by this drying device is directed upwards at an angle of at least 2° and / or at most 10° to the horizontal. Such an orientation of the airflow generated by a drying device makes it easier to dry the upper areas of the two-wheeler effectively.

[0038] The method for cleaning the two-wheeler may include rinsing the two-wheeler during a rinsing cycle using a rinsing fluid to which a gloss drier and / or a chemical drying aid has been added. A gloss drier and / or a chemical drying aid are understood to be additives typically used in the automotive sector that serve to support surface drying and are designated as such. The rinsing cycle takes place, in particular, between the cleaning cycle and the drying cycle. Such a rinsing cycle increases the efficiency and improves the result of the drying cycle, especially by significantly shortening its duration.

[0039] Furthermore, the method may provide that during a loading cycle for inserting the two-wheeler into the device and / or during an unloading cycle for removing the two-wheeler from the device, the movement of the two-wheeler relative to the device is supported and / or caused by a rotatable brush and / or a wheel rotation unit for rotating the wheel of the two-wheeler.

[0040] Both a wheel rotation unit and a rotating brush can exert a force on the two-wheeler suitable for propelling it forward. This propulsion can be used to insert and / or remove the two-wheeler from the device. For this purpose, the control unit may include a loading cycle and / or an unloading cycle in which no liquid is used. The cycle may, if necessary, position rotating brushes at a specific location within the device, provided they are movable. In this context, it is particularly advantageous if, during a loading cycle, the rotating brushes are positioned in the immediate vicinity of an opening through which the two-wheeler is inserted into the device.Accordingly, it is advantageous if the rotating brush is positioned in the immediate vicinity of the opening through which the two-wheeler is removed from the device during a discharge cycle in which the two-wheeler is removed from the device.

[0041] Such a loading cycle and / or such an unloading cycle may also be provided within the framework of methods for cleaning a two-wheeler by means of a corresponding device, if the method does not have a drying cycle and / or the device does not have a drying device.

[0042] To close the opening for inserting and / or removing the bicycle, a door may be provided in front of the opening, attached to the device by means of hinges. The hinges are designed in such a way that the door is held in a specific open position. This allows the bicycle to be handled without having to simultaneously hold the door of the device, for example, to prevent it from slamming shut. This can be achieved, for example, by hinges that have a corresponding friction and / or locking mechanism that keeps the door in a specific open position.

[0043] In an advantageous embodiment, the drying device can be an air blade arranged at an opening for removing the bicycle from the device. Such an air blade ensures that the bicycle inevitably passes over it when removed from the device. In doing so, any residual liquid adhering to the bicycle is essentially "scraped off."

[0044] Further practical embodiments and advantages of the invention are described below in connection with the drawings. They show: Fig. 1 shows an exemplary device in a perspective view, Fig. 2 shows another exemplary device in a sectional view from above, Fig. 3 The device shows Figure 2 omitting the brushes, Fig. 4 shows a perspective view into the interior of an exemplary device, Fig. 5The device shows Figure 4 omitting the ramp and some other parts, Fig. 6 shows an exemplary device with an alternative design including an additional polishing station.

[0045] Especially in Figure 1 It can be seen that the device 1 has a splash guard housing 2. A drying device 3 is arranged inside the splash guard housing 2. The drying device 3 is, in the case of the Figure 1 The drying unit 3 shown in the example is designed as a high-pressure compressor. Alternatively and / or additionally, it can also be designed as a low-pressure blower. This is particularly relevant in the Figures 2 , 3 , 4 and 5 to recognize.

[0046] Furthermore, in Figure 1It can be seen that the device 1 shown there has a ramp 4 for inserting the two-wheeler into the device and / or for removing the two-wheeler from the device. Devices 1 of the type in question can have corresponding ramps 4 at both ends of the device 1, as is particularly evident in the Figures 2 , 3 and 6 can be seen.

[0047] The devices 1 can have doors 5 for closing openings for inserting and / or removing the two-wheelers. Furthermore, the devices can have closable openings 6 on their longitudinal sides. Such closable openings 6 on the longitudinal sides allow for assistive manual cleaning and / or drying of the two-wheeler within the device 1. This can be done, for example, using a lance with a suitable nozzle. The necessary pressure can be provided by the integrated drying unit 3, as exemplified in the Figure 1 is shown. Figure 1 To make the drying device 3 visible, a housing part covering it is not shown.

[0048] The device can, as particularly shown in the Figure 1 and 6As can be seen, the device 1 has an opening 7 on its upper side. Through the opening 7, the handlebars and / or the saddle of a two-wheeled vehicle held in the device 1 can protrude from the device 1. The device 1 can, as is particularly evident in the Figure 1 , 5 and 6 As can be seen, the device has splash guard elements 8 on its upper surface. To close the openings 7, the splash guard elements 8 shown in the examples can be moved towards each other until they come into contact with the parts of a two-wheeler that pass through the opening 7, or until they cover the opening 7, at least substantially. The splash guard elements 8 may have bristles for contact with the two-wheeler. The splash guard elements 8 may be guided in their movement by means of telescopic rails.

[0049] As particularly evident from the examples in the Figures 2 and 3As can be seen, the drying devices 3 can be mounted together with rotatable brushes 9 on brackets 10. The brackets 10 are movable, in particular along the longitudinal direction X of a two-wheeler mounted in the device 1. For better illustration, the following are shown in the Figure 2 The movement ranges of brushes 9 are shown. Figure 3 The brushes are not shown so that the respective holder 10 is more visible. Deflector elements 11 for deflecting the bristles of the brushes 9 are also arranged on the holders 10. The deflector elements 11 result in the bristles of the brushes 9 not having a circular range of motion, but rather, as shown in Figure 2 It can be seen that it is flattened towards the splash guard housing 2. This makes it possible to make the device 1 narrower.

[0050] As especially in Figure 3As can be seen, 8 drying units 3, each designed as a radial blower, can be arranged within the splash guard housing. As can also be seen, for example, in Figure 3 It can be seen that drying units are arranged one above the other. As can also be seen, for example in Figure 3 to recognize that the drying devices 3 are aligned in such a way that they are aligned with a rotatable brush 9 opposite the two-wheeler.

[0051] The devices shown as examples demonstrate, as in the Figures 2 to 5 to identify wheel rotation units 12. These can, as in the Figures 2 to 5 shown to be designed as rotatable rollers.

[0052] As especially in the Figure 5As can be seen, the device 1 can have a height-adjustable support device 13. The support device 13 serves to support the front wheel of the two-wheeler. In particular, the support device 13 can serve to adjust the position of the handlebars of the two-wheeler above the mudguard elements 8. The height adjustability of the support device 13 can be achieved by means of rotatable threaded rods 14. These can be, as in particular in Figure 5 As can be seen, the two-wheeler is arranged on both sides of the device and coupled by a traction element 15. In the example shown, the height adjustment of the support device 13 can be manually effected by means of an actuating device 16 designed as a handwheel.

[0053] In Figure 6 An exemplary embodiment is shown, which differs from the ones described in the Figures 1 to 5The illustrated embodiments differ in particular by an additional polishing station 18. The cleaning station 17 is a device 1 for cleaning two-wheeled vehicles, in particular according to the above description, with a wet cleaning device for cleaning the two-wheeled vehicle by means of a cleaning fluid (in Fig. 6 (not shown) and a splash guard housing 2 for containing the cleaning fluid. A two-wheeler can be at least partially accommodated in the splash guard housing 2 of the cleaning station 17 during cleaning. The cleaning station 17 includes a drying device arranged inside the splash guard housing (in Fig. 6 (not shown) on.

[0054] As in Figure 6As shown, a polishing station 18 can be connected to the cleaning station 17. This polishing station can also have a splash guard housing 2. In this embodiment as well, direction X indicates the longitudinal direction of a two-wheeler received in the cleaning station 17 and / or the polishing station 18. The cleaning station 17 and the polishing station 18 can be separated from each other by a splash guard element 19, as in the example shown.

[0055] In particular, in an embodiment such as in the Figure 6 As shown in the polishing station, 18 rotating polishing brushes are used as a drying device (in the exemplary example). Fig. 6 (Not shown for illustrative reasons). The polishing brushes may have a sponge and / or textile structure to remove adhering liquid residue from the bicycle.

[0056] As in Figure 6As shown by way of example, drying devices 3, in particular designed as blowers, can be arranged in the splash guard housing 2 of the polishing station 18. The drying devices 3 in the polishing station 18 serve in particular to keep the polishing brushes dry. The drying devices 3 in the polishing station can have a lower degree of protection than the drying devices 3 in the cleaning station 17 or the device 1 and / or a lower degree of protection than IP 66.

[0057] The device 1 can furthermore include an air blade 20, which, as a drying device, can be arranged particularly in the area of ​​an opening for removing the two-wheeler from the device 1. Alternatively and / or additionally, an air blade 20 can also advantageously be located in the area of ​​the boundary between the cleaning station 17 and the polishing station 18, as described in Figure 6 The arrangement is shown as an example.

[0058] The features of the invention disclosed in this description, in the drawings, and in the claims can be essential for realizing the invention in its various embodiments, both individually and in any combination. The invention is not limited to the described embodiments. It can be varied within the scope of the claims and taking into account the knowledge of the person skilled in the art.
