Definitions

  • the invention relates to an electrically drivable cleaning device such as a spray extraction device, floor cleaning machine, water and / or vacuum cleaner or the like, on which the plug-in half of a two plug-in halves with mutually complementary plug-in parts, for device-internal distribution of electrical energy, is arranged to produce an electrical plug connection is.
  • an electrically drivable cleaning device such as a spray extraction device, floor cleaning machine, water and / or vacuum cleaner or the like, on which the plug-in half of a two plug-in halves with mutually complementary plug-in parts, for device-internal distribution of electrical energy, is arranged to produce an electrical plug connection is.
  • Cleaning devices of the type mentioned above are mainly used for cleaning floor surfaces, upholstered furniture, textile wall coverings, etc.
  • accessories or devices which are operated together with the cleaning device. These are, for example, spray or suction nozzles, tapping vacuums, attachments with rotating brushes or the like.
  • Many of these additional devices can be driven electrically separately and therefore, like the cleaning device itself, require an electrical power supply. For the sake of simplicity, this is branched off from the power supply of the cleaning device, the one live plug-in half of a plug connection device being arranged on the cleaning device itself. If necessary, only the second plug-in half assigned to the additional device or additional part is to be inserted in order to establish the electrical connection.
  • plug connection devices can also be used when the cleaning device, practically remotely controlled, is to be controlled with regard to its functions from the additional device.
  • the insertion part of the device-side plug-in half is completely unprotected in the unused state to the environment, so that dirt and dust or the like. Can deposit contaminants that can significantly impair the functionality of the connector. These impairments can even endanger the operating personnel if the cleaning device is operated in connection with electrically conductive liquids, as is the case, for example, when using liquid cleaners or when suctioning water. Because liquid penetrating into the plug-in half can quickly cause a short circuit.
  • the invention is therefore based on the goal of a Reini to create machine according to the type mentioned, in which contamination or wetting of the plug-in part of the device-side plug-in half is excluded even when not in use.
  • the device-side plug-in half is assigned a protective cover which shields the plug-in part of the plug-in half from the environment when the plug connection is separated and which can be removed to produce the plug-in connection between the two plug-in halves in order to release the plug-in part.
  • the plug-in part of the device-side plug-in half is shielded from the contaminated environment both when the plug connection is made and when it is disconnected. If the plug connection is not required, it is simply covered or closed by means of the protective cover, and it can neither contaminants such as dust, dirt or the like. still moisture, e.g. Splashing water, penetrate or act on the insert.
  • the protective cover is expediently designed as a protective cover, which is in particular captively arranged on the device-side plug-in half. This means that it is immediately available when needed and is actually used by the operating personnel. It is preferably arranged on a holding part which can be fixed on the device-side plug-in half and which acts as an intermediate piece and in particular is detachably connected to the plug-in half. On the one hand, this simplifies assembly and, on the other hand, allows the protective cover to be designed together with the holding part as a separate protective device which can be adapted to the respective plug-in type and combined with commercially available plug-in halves. Conventional standard parts can therefore still be used as plug-in halves, which do not require any reworking. Old and used equipment can also be easily retrofitted.
  • the mounting part is preferably designed as a mounting frame which can be pulled onto the housing on the device-side plug-in half for fastening, the plug-in half housing being surrounded by the frame in the manner of a ring. In this way, a precise, secure mounting is obtained with simple assembly at the same time, since the plug-in half housing only has to be inserted through the opening delimited by the mounting frame.
  • the device-side plug-in half expediently contains, in the region of its plug-in side assigned to the plug-in part, a particularly circumferential stop collar projecting beyond the housing transversely to the plug-in direction, so that the mounting frame can be arranged in the mounted state on the plug-in half between this stop collar and a wall of the cleaning device housing.
  • the conventional method of fastening the plug-in half to the cleaning device can therefore advantageously be retained; the installation depth is only reduced in the installed state, since the plug-in part protrudes somewhat further from the device due to the interposed mounting frame.
  • the bracket frame is expediently aligned on the outside of its frame sections arranged next to the protective cover with the stop collar, so that the installation width is not changed.
  • the mounting frame is provided with fastening holes which, in the inserted state of the plug-in half housing, have through openings for fastening means such as screws or the like provided on the latter in particular on the stop collar. aligned, so can be attached to the housing at the same time without additional effort and in particular without additional screws, the bracket edge when attaching the male half.
  • the mounting frame is in particular an annular rectangular frame.
  • the usability of the protective cover is particularly simple if it is pivotably arranged on the plug-in half and in this case in particular on the holding part and is designed as a hinged cover.
  • This is more appropriate as attached to the mounting frame two spaced-apart bearing eyes with coaxial bearing openings, between which there is at least one bearing part arranged on the flap cover with a through opening, a common pivot bearing axis being inserted through the openings.
  • the arrangement of bearing eyes and bearing part can also be reversed.
  • the axial length of the bearing part preferably corresponds approximately to the clear width between the two bearing eyes. If the hinged cover is preloaded in the closed state, the protective device is even easier to use.
  • a particularly compact locking mechanism is obtained if a spring receiving space, which is arranged coaxially to the through opening, is provided in the bearing part, in which the lid closing spring, which is designed in particular as a spiral spring, is seated.
  • a longitudinal slot can be provided in the bearing part in the area of the spring receiving space, through which the corresponding spring arm can reach.
  • the other end of the spring is expediently supported in a recess of the holding part adjacent to the spring receiving space, so that no consideration has to be given to the geometry of the plug-in half.
  • the plug-in part of the device-side plug-in half is shielded in a sealing manner.
  • an annular seal is preferably arranged on the protective cover, which in the closed state rests against the end region of the socket surrounding the plug-receiving space.
  • the socket does not require any processing, since existing housing or stop collar surfaces can be used as sealing surfaces.
  • a particularly simple mounting of the annular seal is obtained if it is inserted into an annular surface groove made in the protective cover, with its sealing part projecting slightly beyond the cover.
  • the protective device can be used regardless of whether the plug-in half is designed as a socket or as a plug.
  • the cleaning device shown in FIG. 1 is a combined dust and water vacuum cleaner 1, which is equipped with an additional device in the form of a suction nozzle 3 via a flexible hose 2.
  • the device also contains a connection cable 4 for supplying the electrical energy required for operation and an on / off switch 5.
  • a second switch 6 is provided in the area of the suction nozzle, by means of which the device can also be actuated practically remotely.
  • the electrical connection between the second switch 6 and the cleaning device 1 takes place via a signal cable 7 and with the intermediation of a detachable plug connection device 8. Referring also to FIGS.
  • this plug connection device 8 contains a first plug half 9 which is attached to a wall 10 of the cleaning device 1 is fixed and the 11 on the connection side located in the assembled state in the housing interior 15 contact tabs 14 for soldering device-internal connection cable.
  • this housing side plug-in half 9 is provided with a plug-in section 16 into which the complementary plug-in section 17 of a second plug-in half 18 arranged on the signal cable 7 can be inserted.
  • this plug-in half 9 is assigned a protective cover 19 which, in the closed state shown in FIG. 4, shields the plug-in section 16 from the environment when the plug connection is separated. This shielding function is particularly necessary for so-called wet work, in which liquid cleaning agents or water are used. If the plug connection is to be made, only the protective cover 19 must be removed (FIGS. 2 and 3), so that the plug-in section 16, which is kept free of contamination, is released again.
  • plug-in connection devices are advantageous in all types of cleaning devices, in particular in spray extraction devices, single or multi-disc floor cleaning machines, water and / or vacuum cleaners, polishing machines or the like.
  • the use is not limited to the connection of further actuation switches, in particular so-called cold and / or warm devices can be protected with the protective cover, on which energy for the operation of additive devices such as electrically operated suction nozzles, tapping suckers or the like. can be branched off.
  • the device-side first plug-in half 9 is designed as a socket 20 which has a housing 21, the plug-in part 16 of which is arranged on the plug-in side 22 and has a plug-receiving space 23 designed as a recess. It is suitable for receiving the plug-in section 17 of the second plug-in half 18, which is designed as a plug 24.
  • the assignment of the socket to the cleaning device 1 is particularly advantageous since the current-carrying connection contacts 25 are recessed in the receiving space 23, so that current surges caused by contact are excluded .
  • the arrangement can also be made so that the plug is attached to the housing, while the socket is assigned to the signal cable 7.
  • the protective cover 19 is preferably captively arranged on the device-side plug-in half 19 and, in particular, as is the case with the exemplary embodiment, is designed as a protective cover 26.
  • This is part of a protective device 92 which also contains a holding part 30 which can be fixed on the plug-in half 9 on the device.
  • the mounting of the mounting part on the plug-in half 9 is detachable and that the mounting part 30 is a component that is completely separate from the plug-in half 9.
  • the plug connection device 8 and the protective device 29 are thus working completely independently of one another Units so that existing cleaning devices can be easily retrofitted with the protective device 29 according to the invention without changing or replacing the plug-in halves.
  • the protective device 29 is designed so that it is suitable for protecting commercially available device plugs and / or device sockets. The design is therefore adapted to the usual connector devices, as is the case with the illustrated embodiment.
  • the mounting part 30 is designed as a mounting frame 31 which delimits a frame opening 32, the cross section of which is adapted to the cross section of the housing 21 of the socket 20.
  • the frame opening 32 is therefore rectangular, just like the mounting frame 31 is an annular rectangular frame.
  • the mounting frame 31 is only to be mounted on the socket housing 21 which is essentially equipped with a complementary outer contour, so that the housing 21 is surrounded by the frame 31 in the manner of a ring. 3 and 4 illustrate this installation state, in which the housing 21 is inserted through the frame opening 32.
  • the socket 20 used has on its insertion side 22 a circumferential stop collar 34 surrounding the receiving space 23, which is perpendicular to the insertion direction 35 protrudes beyond the housing 21. It normally serves for the direct fastening of the socket 20 to the device wall 10, for which purpose it contains two mounting openings 36 in addition to the housing, through which a fastening screw 37 can be inserted in each case.
  • the stop collar 34 also serves to fix the mounting frame 31 parallel to the insertion direction 35, in that the mounting frame 30 is arranged in the assembled state between the device wall 10 and the stop collar 34 and is clamped between them. Since the mounting frame 31 advantageously has mounting holes 38 aligned with the mounting openings 36, the screws 37 can also be passed through here, so that existing mounting devices can also be used to hold the protective device 29 at the same time.
  • the protective cover 26 is preferably designed as a hinged cover which is arranged such that it can pivot relative to the plug-in half 9.
  • a pivot bearing 39 is provided between the protective cover 26 and the mounting frame 31. It is located on one of the rectangular sides of the mounting frame 31, whereby, viewed in the insertion direction 35, it projects beyond the stop collar 34, while the other rectangular frame sections 40 are flush with the stop collar 34 on the outside.
  • the pivot bearing 39 contains two bearing eyes 44 which on which a wider frame section 45 is formed in one piece, so that an L results in side view, the shorter leg of which forms a bearing eye 44 in each case.
  • the two eyes 44 are located at one end of the frame section 45 and are provided with coaxial bearing openings 46.
  • the bearing part 47 is part of the protective cover 26 and is integrally formed thereon; both the protective cover and the mounting frame consist in particular of plastic material. Since the axial length of the bearing part 47 corresponds approximately to the clear distance between the bearing eyes 44, there is a precise fixation in the axial direction without impairing the pivotability about the bearing axis 49.
  • the protective cover 26 is arranged essentially in one plane, the bearing axis 49 running parallel and at a distance from it.
  • the bearing part center is thus slightly laterally offset with respect to the protective cover, so that a slightly L-shaped contour also results in the side view according to FIG. 3.
  • the protective cover 26 and the plane of the annular mounting frame 31 lie parallel and at a distance from one another, so that the thickness of the stop collar 34 interposed is exactly balanced.
  • the hinged cover is expediently spring-biased in the closed state.
  • the through opening 48 is provided on one axial side of the sleeve-shaped bearing part 47 with a cylindrical extension, which forms a spring receiving space 50.
  • a lid closing spring 51 which is designed in particular as a spiral spring and coaxially surrounds the bearing axis 49.
  • a corresponding arrangement can be made on the other axial side, and an empty spring receiving space can also be provided there, so that, depending on the embodiment, one or the other space can be equipped with a spring.
  • the two hereinafter referred to as spring arms 52, 52 'ends of the closing spring 51 are supported on the one hand on the cover 26 and the other on the holding part 30.
  • the bearing part 47 is provided with a passage of the one spring arm 52 allowing longitudinal slot 53, while the mounting frame 31 in the wider frame section 45 on the side of the bearing openings 46 contains a recess 54 into which the other spring arm 52 'engages in a supportive manner.
  • the closing spring 51 is preferably made of stainless metal, as is the case with the bearing axis 49. The latter can also be divided into two in the case of simpler exemplary embodiments, one half being assigned to an axial side of the bearing part 47.
  • the protective cover 29 of the exemplary embodiment seals off the plug-in section 16 of the plug-in half 9 in the closed state.
  • the cover 26 is provided on its side facing the receiving space 23 in the closed state with an annular surface groove 55 in which a sealing ring is seated or held, which projects with its sealing part 57 over the cover 26.
  • the surface groove 55 is designed in such a way that, when the cover is closed, it surrounds the receiving space 23 in the insertion direction 35, so that it is ensured that the sealing part 57 bears in the closed state on the area 58 of the socket surrounding the receiving space 23. In this way, there is no need for additional sealing surfaces on the socket, since existing surfaces can be used for sealing.
  • the bearing axis 49 is preferably designed as a thru axle, so that the assembly and disassembly can be carried out quickly and easily. If necessary, the advantageously few parts of the protective device can be replaced individually.
  • FIG. 5 shows a further exemplary embodiment of the protective device 29, the same components being used identical reference numbers are provided.
  • a significant difference to the embodiment according to FIGS. 2 to 4 is that the protective cover 26 is not arranged on the longer rectangular side of the mounting frame 31, but on its narrow side, so that the plug receptacle space 23 is opened to the side and not opened after up there.
