Description

Background of the invention

The The invention relates to a vacuum cleaner for handling in at least two different operating modes, with a separator and filter unit and Suction fan receiving housing.

State of the art

A vacuum cleaner of the type mentioned is from the published patent application DE 196 17 066 A1 known. This vacuum cleaner consists of a bottom part, which is equipped with a wheels and wheels provided suspension and receives the cable drum of the vacuum cleaner. The cable drum wraps the electrical cable equipped with a plug, which serves to supply electrical energy to a motor-suction unit of the vacuum cleaner. The suction hose of the vacuum cleaner opens from the front, the motor-suction unit, which is completely decoupled from the bottom part. The decoupled motor-suction unit subsequently obtains the electrical energy either from an integrated accumulator which is charged at the motor-suction unit mechanically and electrically connected to the bottom part, or is supplied with power by a separately connected mains cable. The electrical coupling of the motor-suction unit with the bottom part is effected by a horizontal sliding movement of the motor-suction unit on a plate-shaped extension of the bottom part, whereby a correspondingly formed connector is closed. The motor-suction unit is subsequently secured by latching on the bottom part and can be removed from the bottom part by releasing the locking by an opposing sliding movement again. The bottom part further has a receptacle for equipment, such as an electric suction brush, and a handle on which the bottom part can be isolated or carried with coupled motor-suction unit.

This Stabsauger can with attached motor-suction unit on the one hand as conventional floor vacuum cleaner can be used. The decoupled motor-suction unit serves as a hand vacuum cleaner. A change of the suction hose is not required, but this can be done with attachments, For example, a suction nozzle, be provided. Further it is possible to use the decoupled motor-suction unit with equip a device handle to their handling too simplify. Although this is already a fairly variable usable vacuum cleaner provided, but still in terms of its scope is in need of improvement. In addition, the Vacuum cleaner through the coupling devices structurally very expensive be.

In the patent DE 100 63 022 C1 is a suitcase, in particular for stowing and the transport of hand tools, described, the housing is also equipped with a suction device in addition to the recordings for the transport and storage. The suction device can be firmly integrated into the housing or arranged in a detachable housing part. In this case, components of the hand tool, such as accumulators, drive units, power supplies or the like, can also be used to operate the suction device. The air intake and exhaust openings are embedded in the housing, so that the suction device can be operated without opening the housing. Furthermore, the housing is provided with a socket which can serve to supply the hand tool, for example a drill, with electrical energy and automatically turns on the suction device when the hand tool is put into operation.

The patent application GB 2 330 521 A discloses a toolbox which is comprised of a suction and filter unit integrated in the base region and a suction hose which can be stowed on the outer circumference of the toolbox. The tool box comprises two separable housing parts, one of which serves as a dust collection box and can be separated for emptying from the other, considerably larger housing part.

Another toolbox with a suction and separation device is in the European patent application EP 1 382 285 A2 described. The tool box is closed from above by a trough-like lid, which is connected by hinges rotatably connected to a longitudinal edge of the housing of the tool box and is pivoted to open by 180 °. The now accessible lid underside serves to stow the suction hose and various accessories. The housing is provided with a chamber-like partition with vertical walls, which receives the deposited dust from the sucked air. Beyond the chamber, the suction fan is arranged, which is on the other hand fluidly connected to an opening in the housing wall on the one hand and with the chamber-like separation. The opening is used for coupling the previously detached from the lid suction hose. The lid also has on its upper side a pivotally mounted handle, which can serve for carrying the tool box and for winding up the tool box supplying electrical power to the power cable. Although these tool boxes known from the prior art are versatile in their use, they can be insufficiently variable with regard to their suction function.

Detailed description the invention with reference to an embodiment

The in 1 shown vacuum cleaner 1 has a cuboid housing 2 on with a rectangular top 3 , a rectangular base 4 , rectangular side surfaces 5 , a front square narrow side 6 and a rear square narrow side 7 , On the bottom 4 of the housing 2 there are wheels 8th when not in use in the housing 2 can be swung. In principle, wheels can also be provided for vertical use on the rear side. On the top 3 and in the side areas 7 are lids 9 . 9 ' arranges, after the opening of the access to the interior of the housing 2 is possible. The front narrow surface 6 has a suction opening 10 on which with the vacuum source of the vacuum cleaner 1 fluidly connected. On the opposite narrow side 7 are a circular opening 11 and a horizontal handle extraction slot 12 arranged. In the case 2 is also an unillustrated, wound on a drum power cord for the supply of electrical power and various actuators, such as switches or sliders housed.

All location and direction information refer to the orientation of the housing as shown 1 ,

As from the cut 2 can be seen, are in the central area of the housing 2 one after the other a separation and filter unit 13 and a suction fan 14 arranged with the suction opening 10 communicate. The suction opening 10 is with the separation and filter unit 13 via a housing-fixed tube storage 15 connected, which one of this extendable pipe socket 16 receives. Inside the pipe socket 16 is also a stretchable suction hose 17 arranged, which is both inserted and withdrawn pipe socket 16 can be pulled out to extend the suction. The one in the narrow side 7 provided excerpt opening 11 flows into a cylindrical storage shaft 18 in which a telescopically pullable suction tube 19 stowed. The storage shaft 18 extends below the tube store 15 , the separating and filtering unit 13 and the suction fan 14 over the entire length of the housing 3 , In the intake manifold 19 is another stretchable suction hose 17 ' arranges, with an adapter for connection to the suction hose 17 Is provided. In the side areas 5 of the housing 2 are storage compartments 20 let in, after opening the lid 9 ' are accessible. The one in the narrow side 7 recessed grip pull-out slot 12 also opens in two laterally in the longitudinal direction of the housing 2 extending handle receiving slots 21 one which the thighs 22 a bow-shaped handle 23 take up.

Im in 3a shown operating mode "vacuum cleaner" is the suction tube 19 manually through the pullout opening 11 through from the associated storage shaft 18 of the housing 2 taken and pulled apart telescopically, with the suction tube 19 stowed suction hose 17 and in the pipe socket 16 mounted suction hose 17 stretched and coupled together. On the far end of the suction tube 19 is also a previously in a storage compartment 20 stowed floor brush 24 attached. The pipe socket 16 is still in the case 2 inserted, since it is not needed in the current operating mode. The wheels 8th are extended to the housing 2 to be able to move across the ground with little friction.

In operation, hand vacuum cleaner, which in 3b is shown, the pipe socket 16 on the narrow side 6 out of the case 2 pulled out locked in this position and at its projecting end with the floor brush 24 Mistake. On the opposite narrow side 7 is the suction tube 19 only partially out of the case 2 pulled out and locked in this position. It serves as a handlebar in this position 25 for guiding the vacuum cleaner 1 , The locking of pipe sockets 16 and handlebar 25 For example, by using a bayonet-type closure device by twisting relative to the housing 2 respectively. The suction hoses 17 . 17 ' as well as the wheels 8th remain in stowed position because they are not needed for this mode of operation. By using a significantly enlarged floor nozzle this hand vacuum cleaner could basically be further developed in the direction of an "up-right" vacuum cleaner, which is particularly common in the American market.

When using the vacuum cleaner 1 in the operating mode "handheld" (= hand-guided) vacuum cleaner ( 3c ) are the pipe socket 16 and the bow-shaped handle 23 pulled out of the housing and locked. The wheels 8th and the suction hose 17 ' stay in stowed position. The suction hose 17 is still in the pipe socket 16 accommodated, but can be pulled out temporarily if necessary to extend the suction section from this. After use, the suction hose pulls 17 automatically in the pipe socket 16 back.

3d shows the vacuum cleaner 1 in his parking position, in which he upright on the narrow side 6 stands. To carry the bow-shaped handle 23 temporarily from the narrow side 7 be pulled out. Otherwise, the handle is 23 as well as the pipe socket 16 , the suction tube 19 and the suction hoses 17 . 17 ' flush in the housing 2 stowed, so the space required when stowing the vacuum cleaner 1 is minimized.
