DETAILED DESCRIPTION
[0181]
[0182]
[0183] It can be seen from
[0184] The suction cleaning attachment 1 shown schematically in perspective in
[0185] Accordingly, the outer diameter of the handle area 14, in particular the handle section area 13, is between 4 cm to 15 cm, preferably between 6 cm to 10 cm, in particular at least substantially 7 cm.
[0186]
[0187] The switch 16 shown in
[0188] The switch 16 shown in the embodiment examples has a swivel lever 51 that can be pivoted to different positions for controlling or releasing the compressed air flow. The swivel lever 51 is pivotably mounted at one end, with its other, free end being designed for switch actuation, in particular having an actuating section.
[0189] Not shown is that the switch 16 may also be configured as a push button switch and/or a switch plunger. Finally, in further embodiments, the switch 16 is configured such that, on the one hand, it is adjacent to the handle area 14 or is arranged in the handle area 14 and can be actuated by the user's hand encompassing the handle area 14.
[0190]
[0191] The switch 16 can have the swivel lever 51 and a switch housing 52 as its outer housing, as shown for example in
[0192] The compressed air connection 15 can be arranged on the switch housing 52, as can be seen in
[0193] In the embodiments shown, the switch housing 52 is arranged on the housing 4 of the suction cleaning attachment 1 in such a way that it adapts and/or fits the shape of the housing 4. This makes it possible to implement a switch 16 with the lowest possible installation height of a few centimeters, in particular from 1 cm to 3 cm.
[0194] In the illustrated embodiments, the swivel lever 51 is pivotable and/or displaceable from at least one blocking position blocking the compressed air flow shown in
[0195] The transfer of the swivel lever 51 into the release position starting from the locked position can be carried out by an adjustment force exerted on the swivel lever 51 against the spring force of the spring 17 by at least one finger of the hand of a user that encompasses the handle area 14 at least in some areas.
[0196] The swivel lever 51 can be pivoted and/or displaced from the release position to the locked position by the spring force of the spring 17. In order to move from the locked position to the release position, a force must ultimately be exerted on the swivel lever 51. However, due to the spring force of the spring 17, the swivel lever 51 can be returned “independently” from the release position to the locked position without external force being applied.
[0197] In order to fix the swivel lever 51 in the release position shown in
[0198]
[0199]
[0200]
[0201] Ultimately, the spring 17 is tensioned by pivoting the swivel lever 51, this being shown in
[0202] The actuating means 40 interacts with the release means 41 in such a way that the actuating means 40 can lead to the rotation of the release means 41. The release means 41 is preferably designed as an eccentric disc. In particular, the actuating means 40 can engage in the release means 41 and/or be guided through the release means 41. The actuating means 40 has, at least in regions, an at least substantially rectangular cross-sectional shape, as can be seen from
[0203] Of course, the actuating means 40 also causes the release means 41 to rotate when the swivel lever is pivoted and/or shifted from the release position to the locked position. The locked position and the interaction between the actuating means 40 and the release means 41 can be seen in
[0204]
[0205] The lock 42 is slidably mounted in a guide channel 44 having a channel opening 43. The guide channel 44 is shown in
[0206] The compressed air is guided through the guide channel 44 and made available via the compressed air connection 15. The compressed air present in the guide channel 44 is blocked in the blocking position of the switch 16 by the lock 42 closing the channel opening 43. A lock 42 closing the channel opening 43 is shown in
[0207]
[0208] Ultimately, the lock 42 can be displaced in the guide channel 44, wherein in the locked position of the switch 16 and/or the swivel lever 51, it closes with and/or nestles against the release means 41 in such a way that the channel opening 43 is blocked and/or closed.
[0209] In this case, the channel opening 43 may have a shape and/or cross-section corresponding to the shape of the lock 42, in particular having an at least substantially circular and/or round cross-section.
[0210] The guide channel 44 can be designed in such a way that the lock 42 can be guided along the inner wall of the guide channel 44.
[0211] The webs 58 are designed in such a way that in the release position of the switch 16 and/or the swivel lever 51, the compressed air can be transferred and/or flow from the guide channel 44 via the channel opening 43 into the compressed air channel 5. In the process, the compressed air can ultimately flow past the lock 42 next to the webs 58. Accordingly, the webs 58 serve, among other things, for contacting as well as for fixing and for displacing the lock 42 in the guide channel 44. Furthermore, the webs 58 form areas through which the compressed air can flow past the lock 42, these areas being created and utilized in the release position of the switch 16 and/or of the swivel lever 51.
[0212]
[0213] In particular, the webs 58 can be formed as protrusions that project beyond the side walls or the base surfaces of the side walls of the guide channel 44. In particular, the guide channel 44 has an at least substantially rectangular cross-section, as shown in
[0214]
[0215] In the locked position of the switch 16 and/or the swivel lever 51, the protrusions 45 of the release means 41 are arranged adjacent to the lock 42 in such a way that the channel opening 43 is closed, as can be seen in
[0216] The switch 16 shown in the embodiments can be pivoted and/or displaced via the swivel lever 51 in two opposite directions into a respective release position starting from the locked position. In this context, the aforementioned protrusions 45 are shown to be particularly advantageous, since two protrusions 45 can ultimately ensure that, starting from an at least substantially central locking position of the switch 16 and/or of the swivel lever 51, the swivel lever 51 can be transferred into the release position, namely in two different directions. If only one protrusion 45 of the release means 41 were present, the swivel lever 51 could also be pivoted in only one direction.
[0217] The compressed air line 27 of the compressed air channel 5 can be guided into the switch 16, in particular into the switch housing 52, at least in some areas, as shown in
[0218] In the embodiments shown, the cross-sectional area of the compressed air opening 6 of the compressed air channel 5 is about 20 mm.sup.2. In further embodiments, which are not shown here, the cross-sectional area of the compressed air opening 6 of the compressed air channel 5 can be between 0.5 mm.sup.2 to 100 mm.sup.2. In the illustrated embodiment, the cross-section of the compressed air channel 5 has an at least substantially circular basic shape and further has a diameter of about 5 mm.
[0219] The cross-sectional area of the suction opening 7 of the suction channel 3 shown in
[0220] During pressurized operation, an overpressure of 7 bar is provided in the compressed air channel 5 or the compressed air exits the compressed air channel 5 at the aforementioned overpressure. In further embodiments, the overpressure can be between 5 bar to 10 bar. In the suction channel 3, on the other hand, there is a negative pressure, which in the embodiments shown is about 0.5 bar. In further embodiments, the negative pressure can be between 0.3 to 0.8 bar.
[0221]
[0222] The housing 4 has a handle section 8 comprising the handle area 14, a housing nozzle 9 detachably connectable to the handle section 8, and an end piece 10 detachably connectable to the housing nozzle 9. The end piece 10, which is subject to greater wear than the rest of the housing 4, can be replaced independently of the other components of the housing 4. The detachable connections of the components 8, 9, 10 of the housing 4 to each other allow access to the interior of the housing 4.
[0223] Furthermore, in the illustrated embodiment example, it is shown that the end piece 10 is beveled at the end, facing away from the housing nozzle 9.
[0224] The housing nozzle 9 can be detachably connected to the handle section 8 in a form-fit, force-fit and/or friction-fit manner. The end piece 10 can in turn also be positively, non-positively and/or frictionally connected to the housing nozzle 9. Ultimately, the connection is such that loosening of the aforementioned components during use of the suction cleaning attachment 1 can be at least substantially avoided.
[0225]
[0226]
[0227] Furthermore,
[0228] In addition,
[0229]
[0230]
[0231] Not shown is that the suction channel 3 has a pipe section 11 inserted into the housing nozzle 9. The pipe section 11 can project into the handle section 8 and into the end piece 10.
[0232] In the embodiment shown, the compressed air channel 5 is designed as a compressed air line 27 and is arranged at least in some areas in the housing nozzle 9 and in the handle section 8. The compressed air line 27 can be designed as a hose, in particular a plastic hose. Furthermore, the compressed air line 27 ends in the end piece 10, wherein the compressed air channel 5 is subsequently formed by a channel of the end piece 10 adjoining the compressed air line 27 in the direction of flow.
[0233] Not shown is that the compressed air line 27 is held on the pipe section 11. In this case, the compressed air line 27 can be clamped to the pipe section 11 and/or held by the pipe section 11 via corresponding holding means.
[0234] It is not shown that the compressed air channel 5, in particular the compressed air line 27, is separated at least in some areas from the suction channel into the housing nozzle 9 by at least one separator bar 46. The separation strip 46, which is not shown, can be fixed by a screw connection to the housing nozzle 9 and to the inner wall 47 of the housing nozzle 9. The screw connection can be seen schematically from the exploded view in
[0235] The compressed air channel 5 shown in
[0236] It is not shown that the separator bar 46 is connected to the inner wall 47 of the housing nozzle 9, in particular by screw connections.
[0237] In addition, in further embodiments, it can be provided that corresponding recesses are provided on the inner wall 47 of the housing nozzle 9 and/or on the inner wall of the handle section 8 for the compressed air line 27 for receiving the compressed air line 27 at least in certain areas. Through the recesses, which are not shown in more detail, the compressed air line 27 can be guided safely through the handle section 8 and/or the housing nozzle 9.
[0238] It is understood that in further embodiments not shown, a channel receiving the compressed air line 27 may also be provided, in particular adjacent to the inner wall 47 of the housing nozzle 9 and/or the inner wall of the handle section 8, which channel receives the compressed air line 27 and ultimately leads to the end piece 10.
[0239] Moreover,
[0240] Furthermore,
[0241] The suction channel 3 can taper towards the suction opening 7 in the area of the handle section area 13 and the housing nozzle 9.
[0242] The switch 16 and the switch housing 52 are arranged on the handle section 8 in the illustrated embodiment examples.
[0243]
[0244] In
[0245] Furthermore,
[0246]
[0247] It is not shown that a lighting device 18 can be provided on the suction cleaning attachment 1. The lighting device 18 has at least one LED. Furthermore, in an embodiment not shown, the lighting device 18 is held on the pipe section 11 and on the housing nozzle 9. In further embodiments not shown, the lighting device 18 can be arranged on the end piece 10, on the housing nozzle 9, on the handle section 8, on the bracket 14 and/or on the pipe section 11, and in particular can be firmly connected to the aforementioned components.
[0248] Further not shown is that the lighting device 18 is connected via at least one line 19 for carrying current. The line 19 is connected to a power connection 24, which may be provided on the switch 16. The line 19 may be held on the pipe section 11 and supplied to the lighting device 18 on the opposite side of the pipe section 11 from the compressed air line 27.
[0249] In further embodiments not shown, the line 19 may be arranged and/or retained on the inside of the pipe section 11, on the outside of the suction channel 3 and/or on the inside of the end piece 10.
[0250] In an example embodiment not shown, the power connection 24 may be provided adjacent to the compressed air connection 15.
[0251] Further not shown is that the lighting device 18 is arranged on the housing nozzle 9 and on the pipe section 11 in the channel 33 and in the housing nozzle 9. The end piece 10 can partially cover the housing nozzle 9 on the outside, so that the lighting device 18 can also be surrounded by the end piece 10 on the outside.
[0252] In an embodiment not shown, the lighting device 18 is arranged on the outer side of the pipe section 11 facing the housing nozzle 9. The light beam and/or cone of the lighting device 18, which has the at least one LED, in the illustrated embodiment example two LEDs, emerges from the light exit opening 34. An LED cover protects the LED and/or the lighting device 18 from contamination. The resulting light beam is larger and/or wider than the generated light beam due to the distance of the light outlet opening 34 from the suction opening 7 or the compressed air opening 6 when using the suction cleaning attachment 1 for cleaning an interior of motor vehicles.
[0253] The suction cleaning attachment 1 shown in
[0254] Not shown is that a bracket-like line fastening means 28 adjacent to the compressed air connection 15 is fastened at the end side of the connection end 12 facing away from the end piece 10, which is designed to fix the line of the compressed air device 21 and the energy supply device 25, for example by means of cable ties.
[0255] The suction cleaning attachment 1 shown in
[0256] A holder of the suction cleaning attachment 1 in the quiver 48 is shown, for example, in
[0257] Furthermore, the handle area 14 can additionally be understood as that area of the suction cleaning attachment 1 which, when the suction cleaning attachment 1 is inserted into the quiver 48, is arranged outside the quiver 48 or above the outer edge 57 of the quiver 48.
[0258]
[0259] It is not shown that the stop 49 is designed as a step.
[0260]
[0261]
[0262]
[0263]
[0264]
[0265] It is not shown that the stop 49, which is designed in particular as a step, is arranged on the outside of the housing nozzle 9. In this case, the stop 49 would not necessarily have to protrude over the handle area 14, the handle section 8 and/or over the connection end 12. However, the stop 49 should be designed to limit the insertion movement into the quiver 48. This ultimately presupposes that behind the stop 49—facing the suction opening 7—no elevation or enlargement of the suction cleaning attachment 1 and/or of the housing 4 exceeding the stop 49 is provided.
[0266]
[0267]
[0268]
[0269] The further compressed air line can be designed as a compressed air connection line 36.
[0270] The switch 16 of the suction cleaning attachment can release the compressed air flow provided by the compressed air connection line 36 and accordingly transfers the compressed air flow into the compressed air channel 5. Ultimately, the switch 16 can block the compressed air flow provided by the compressed air connection line 36 and not transfer the compressed air flow into the compressed air channel 5.
[0271] Not shown is that the lighting device 18 is connected to an energy supply device, which provides the required current for the lighting device 18, via a power connection via a further power line. In further embodiments, the energy supply device may comprise an energy storage device, for example an accumulator. The energy supply device may also be configured as a connection to the public power grid. Furthermore, in an embodiment not shown, the energy supply device may be controlled via a control cabinet.
[0272] Not shown is that the light device 18 of the suction cleaning attachment 1 can be coupled to the fan device 20, the switch 16 and/or the compressed air device 21, in particular the valve of the compressed air device 21. Thus, switching on of the lighting device 18 may be provided in suction mode and/or in compressed air mode. Furthermore, a plurality of illuminants of the lighting device 18 may be provided, which may be controlled independently of each other, for example.
[0273] The suction cleaning attachment 1 is torsionally rigidly connected to suction hose 26 in the embodiment shown in
[0274]
[0275] Not shown is that at least one electrical connection line 35 connecting the lighting device 18 to a power supply device is connected to the suction hose 26 via at least one fastening means 29. The connection line 35 may be connected to the power connection.
[0276] The fastening means 29 is connected to the grooved suction hose 26 via a detachable snap-in connection.
[0277]
[0278] The fastening means 29 has a receptacle with at least two, in the embodiment example shown in
[0279] Two reception areas 39 are provided for the at least one electrical connection line 35, which is not shown, so that the fastening means 29 can be latched to the suction hose 26 independently of the receiving area for the electrical connection line 35, as is also apparent from
[0280]
[0281] Furthermore,
[0282] A quiver 48 is provided according to
[0283] In
[0284] In the case of the quiver 48 shown in
[0285]
[0286]
[0287] In further embodiments, the outer diameter of the outer edge area 57 of the quiver 48 can be at least substantially equal to the outer diameter of the stop 49 of the suction cleaning attachment 1. In this case, the mutually facing surfaces of the stop 49 and of the step formed in the quiver 48 rest on one another, so that the stop function described above ultimately results.
[0288] The stop 49 of the suction cleaning attachment 1 interacts with the outer edge 57 of the quiver 48 in such a way that an at least substantially pressure-tight closure results. The pressure-tight closure results in the non-use state. In particular, the negative pressure is continuously provided by the fan device 20. Due to the pressure-tight closure, an at least substantially self-contained system can be provided, provided that the cleaning device 2 comprises only a suction cleaning attachment 1.
[0289] In
[0290]
[0291]
[0292] In particular, at least one pressure sensor can be assigned to the control device 24, which in particular measures and/or determines the pressure difference to be overcome. Provided that the suction cleaning attachment 1 is inserted into the quiver 48 and there is a pressure-tight seal between the outer edge 57 of the quiver 48 and the stop 49, the pressure difference in particular is very small. As a result, the electrical energy provided by the energy supply device 25 for the fan device 20 can be reduced.
[0293] In the operating state, however, there is a pressure difference to atmospheric pressure (approx. 1 bar) which ultimately ensures “suction operation”. To provide the continuous suction air flow and the vacuum required for this purpose, the pressure difference is maintained, particularly in the operating state, and thus the electrical energy required for this purpose is also provided by the energy supply device 25.
[0294] The method for cleaning the interior of motor vehicles is not shown in the illustrated embodiments. In the method for cleaning the interior of motor vehicles, the cleaning device 1 explained above is used. For interior cleaning, dirt and/or particles are extracted in suction operation, and dirt and/or particles can be swirled up during suction operation in compressed air operation by means of a compressed air flow.
[0295] The compressed air mode can be switched on via switch 16. Thus, the process can be operated in a suction mode, a compressed air mode, a suction and compressed air mode and a suction mode with the compressed air mode being switched on as required. Particles that are difficult to access in particular can be swirled and/or stirred up by the compressed air flow and then sucked up via the suction air flow. In this way, the process can be used to reliably remove dirt particles from areas of the interior of motor vehicles that are difficult to reach. In addition, the dirt particles can be removed from hard-to-reach areas and blown and/or transported into easy-to-reach areas by means of the compressed air flow. Subsequently, the dirt particles can be sucked up or removed from the easily accessible areas by the suction air flow.
