Definitions

  • the invention relates to a wet and dry vacuum cleaner equipped with wheels with a motor-blower unit and a settling chamber arranged upstream thereof via a filter.
  • Such wet and dry vacuum cleaners are widely used to accommodate larger quantities of suction material or even larger pieces of suction material. They can be used, for example, in the house and garden to pick up coarser waste as well as moist waste, such as leaves, they can be used for a variety of purposes in industry and commerce, and there is also the possibility of using them to puddle water yourself to absorb spilled liquids or the like.
  • the barrel-shaped container forming the settling space also represents the main load-bearing component: a wheel construction is connected to the base of the container, which is usually made of sheet steel for reasons of stability, while the motor-blower unit in one connects the vacuum cleaner pre-closing lid see is.
  • the invention is therefore based on the task of creating a wet and dry vacuum cleaner which is easy and safe to move as a result of good running properties and a low center of gravity, and which on the other hand allows the device to be opened easily and with only a small amount of force, and at which also results in the emptying of the container provided as a settling space being simple and problem-free.
  • a wheel-like, carriage-like undercarriage with a structure at its lower end that has the motor-blower unit and a storage space for a removable container, which is covered by an upward-pivoting lid, which has an opening connected via a hose and / or pipeline to the suction connection of the blower, and in that the container and / or the lid are equipped with a connecting device for a suction hose.
  • the chassis By designing the chassis as an independent car, the container provided as a storage area is not only freed from all other load-bearing functions; the deep arrangement of the motor-blower unit, which is now possible, achieves a desired low center of gravity, which further improves the driving characteristics.
  • the emptying of the container is very simple: it is only necessary, after switching off the motor-blower unit Remove the lid from the upper free opening of the container so that it can be removed from its storage space. This also gives you the opportunity to work with several containers, possibly of different sizes: During work, with the container full, only a short interruption is required to swing up the lid and replace the container. The actual emptying can take place in subordinate process steps, and since only simple containers are used in principle, the effort of holding several interchangeable containers is low.
  • containers of different sizes can be used, for example by providing latching projections on the standing surface in order to keep containers of smaller diameter also central, and in adaptation to this it is possible to equip either different containers with edge areas of the same diameter , or to accommodate seals of different effective diameters on the cover.
  • a chassis 1 which can be moved by means of wheels 2 and 3.
  • the wheels 3 of larger diameter are expediently provided in pairs with a relatively large distance, while only one of the pivotally held wheels 2 is optionally provided in the center, or the wheels 2 can be arranged with a reduced base.
  • the undercarriage 1 has a frame-like enclosed storage area 4, on which a separate and relatively simply designed container 6, which is equipped with recessed grips 5 to facilitate handling, is applied.
  • a structure 7 is provided at one end, in the lower part 8 of which the motor-blower unit 9 is provided. Not shown in the figure is an expedient pressure connection leading to the right, by means of which the motor-blower unit can also be used as a compressor.
  • a suction pipe 10 is connected, which seals against a joint 15 on the end face of a connecting pipe 12, which is provided in a substantially prismatic cover 11 which is pivotable about an axis 13 or a hinge which be carried by body 7.
  • the free end of the connecting tube 12 passes through an opening provided in the lower surface of the cover 11 and is in turn overlaid by a filter 16. Also not shown is the support of the lower surface of the cover 11, which may be slightly set back against the circumferential lower edge, which rests on the free end surface of the container 6 by means of a soft-elastic seal. Another opening in the lower surface of the cover 11 leads to a swivel sleeve 14 pivotably arranged in the cover 11 for the connection of suction hoses or suction pipes.
  • the inner end of the swivel sleeve has a lateral opening and extends into a closed trough of the cover 11, which is only opened downwards in the direction of the container 6, and the mouth of which is optionally covered by further, downwardly projecting wall areas against the filter 16 .
  • the filter itself can also be equipped with a covering. It has also proven to be expedient to assign a ball float valve to the mouth of the connecting pipe 12, the specific light ball of which, for example, a table tennis ball, is provided by a possible surge of water is raised and pressed against a sealing seat, so that at least the connecting pipe 12 is protected from the ingress of water, but also expediently the filter 16 from soaking.
  • the filter 16 can be surrounded by a housing, for example made of plastic, which has the ball float valve in the core area and encompasses the actual filter material with jacket areas.
  • a wet and dry vacuum cleaner constructed in this way has good driving properties as a function of the task: due to the low positioning of both the container 6 and the motor-blower unit 9, a desired low center of gravity results, the wheels 3 of large diameter result in a correspondingly good driving behavior while the swiveling wheels 2 ensure steerability.
  • Handles are expediently provided for handling, which extend outwards or can be provided in depressions, but were not taken into account in the figure.
  • the handling of the suction hose does not cause any problems, since the swivel sleeve 14 can be swiveled as desired and overlaps the smooth upper surface of the wet-dry vacuum cleaner.
  • the containers themselves are of a very simple construction and are therefore inexpensive to manufacture, so that replacement containers can be easily obtained.
  • a level indicator, pumps for spraying or cleaning agents or the like can be accommodated in the upper areas of the structure 7, but expediently also in its essentially closed lower part 8.
  • an outward connection of the pressure side of the blower can also be provided, so that the motor-blower unit can also be used as a compressor.
  • the motor-blower unit can also be used as a compressor.
  • it can also prove to be useful in this lower part to accommodate the motor-blower unit, at least in some areas, with comprehensive components which limit the noise emission by material and / or shape and, if possible, prevent it.
  • a further advantage is that not only different container sizes can be used in the selected structure, but also different types can be achieved with the same structural parts, in that the motor of the motor-blower unit can be selected from several motors of different powers already during construction, so that the wet and dry vacuum cleaner can be driven, for example, with a motor of 800 watts, but motors of 1 kW, 1.1 kW or 1.2 kW can also be used to increase the output without the list of those mentioned by way of example Services are to be regarded as exhaustive.
  • handles are provided at different points in the figure to relieve the depiction, which can be designed as a rod, handles of shorter length or as recessed handles.
  • the cover 11 is expediently equipped with soft seals which rest on, surround or engage in container edges, which can be designed according to one container size or else several container sizes. It has proven to be advantageous to cover 11 and chassis 1 at the left-hand end with a semi-circular base equip che; on the other hand, it is also possible to use not only round, but also an elliptically shaped base container 6 as well as containers which are closed off from the structure 7 by a flat flank. In all of these cases, in addition to improved driving properties, considerable ease and simplification of operation are achieved.
  • FIG. 2 A modified embodiment is shown in FIG. 2 in a side view and in FIG. 3 in a top view.
  • the removable container 29 is equipped with a connecting sleeve 17 for a suction hose.
  • the sealing cover 11 carries the filter, not shown here.
  • the motor 18 is turned away from the rear wall 28 and the fan 19 driven by it is arranged facing the rear wall. From the blower, the suction channel 20 extends up to a transverse channel 21 provided at the level of the lid hinge. Care is taken here that when the lid 11 is opened, for example for cleaning or replacing the filter, dirt adhering to it does not get into the Suction line is taken over by interrupting it.
  • Hinge tubes 23 are provided as hinge bolts. They have a grip disk 25, which is also effective as a stop and seal, from which a tubular extension 24 extends, which is equipped with a groove 26 and a side window 27. When inserted, the groove 26 is pushed over a projection of the fixed hinge middle part and is thus connected to the latter in a rotationally fixed manner. A tight, tight fit is achieved by a tight fit, possibly using a locking ring groove, so that the fork ends of the cover are used as a share tubular bolt acting on the tubular bolt are pivotable. As the top view of the cover 11 of FIG.
  • the suction channel of the cover leads into two diverging side channels 22 in such a way that they lead in front of the tube extensions 24 of the hinge tubes 23.
  • Their windows 27 are arranged so that they are in front of the outlet openings of the side channels 22 when the lid 1 is closed. - If the cover 11 is now pivoted up, the outlet openings of the side channels 22 also pivot and run around the pipe extensions 24, leave the windows 27 and are sealed by the lateral surfaces of the pipe extensions 24 following the windows in the pivoting direction.
  • the open ends of the pipe lugs are always connected to the suction channel 20 via the transverse channel 21 formed between them.
  • the inner wall 34 is expediently designed to be solid, while the outer rear wall 28 can be removed or swung out.
  • the space 31 between them can be used to accommodate additional and / or spare parts.
  • a further space 30 located underneath, as well as otherwise unused parts of the engine and blower compartment, can accommodate additional or control units, for example special spray pumps and tanks belonging to them, but also switching means and the like.
  • the suction channel 20 is also connected to the inner wall 34 and passed through the space 31.
  • a container 29 which has a recess into which the motor 14 engages.
  • a vertically continuous recess is expediently provided.
  • the motor-blower chamber and channels 33 are used for the air flow, which result from the lateral gripping of the container.

  • a winding device for the power cord is also preferably provided in the lower regions.
  • a spray pump including the required tank and the spray line
  • an additional, closed unit which, for example, can be hung in front of the rear wall 28 and can be operated via separate sockets.
  • FIG. 7 shows a further modified wet-dry vacuum cleaner in a side view, parts known from FIGS. 2 and 4 not being described in particular.
  • Handling is facilitated in that not only is the container 29 provided with handles, recessed grips or the like, as shown in FIG. 1, but also the lid 11 is equipped with a handle, the carrying handle 35.
  • the handle 35 is provided with a manually operable latch lever 36, the latch arm 37 of which is expediently not provided by a biased spring shown, in the starting position engages behind a solid surface of the structure 7, so that the lid 11 is locked to the structure.
  • the wet-dry vacuum cleaner can be lifted as a whole or who can be directed by means of the handle that without the risk of lifting the locked lid.
  • the lid is to be opened, for example for exchanging or checking the container 29 or the filter insert 50, then with the gripping of the handle 35 the ratchet lever 36 is also gripped and pivoted against the force of a spring biasing it so that the Pawl of the pawl arm 37 is pulled out from behind the surface of the structure 7 holding it and the lock is thus released.
  • the lid can now be pivoted upwards separately, whereby, as described in particular in connection with FIG.
  • the suction channel 20 of the blower 19 is covered by the hinge tubes 23 with the pivoting of the lid, so that the side channels 22 are no longer connected to the suction nozzle of the blower 19 are connected and there is no longer any risk of sucking in unfiltered air.
