The invention relates to a cleaning device, in particular a vacuum cleaner, which has a housing portion on which a handle for carrying the cleaning device is provided.

From the WO 86/01089 A1 a cleaning device with a housing portion and a handle disposed thereon is known. At least one projection, which is assigned to the handle, is provided on the housing section. This projection forms with a sliding closure, which is associated with the handle, a receptacle for attaching a cable winding. This closure forms in the closed position with the projection an open-edged, U-shaped receptacle.

From the US 2,037,668 shows a receptacle for a cable winding, which is formed on a support rod by two L-shaped curved angle, which are aligned in opposite directions to each other.

From the DE 94 13 299 U1 a vacuum cleaner is known in which a housing is associated with a style having a handle. The style above the housing, a first projection for a cable winding is provided. On the housing a handle held on one side on the side wall of the housing is arranged, so that the projection and the handle together form a receptacle for a cable winding. This handle is rotatably mounted to permanently fix the cable winding on the vacuum cleaner after winding. Such a permanent fixation of the cable winding is conditionally user-friendly, since at a not properly done wrapping the lower deflection point or the handle twisting of the handle for permanent fixation is at least difficult. An analog recording for a cable winding is from the DE 34 30 402 A1 known.

From the CH 244 023 A1 as well as from the US 2008/0 189 899 A1 are each mobile vacuum cleaners known which on a shell a handle , wherein a receptacle for a cable winding is formed around the handle around.

Furthermore, a cleaning device from the DE 10 2004 005 500 A1 known. This vacuum cleaner comprises a vacuum cleaner housing with a lower part and an upper part, wherein the lower part has a dirt collecting container and the upper part receives an electric suction unit. The upper part comprises a housing portion on which a handle is arranged to guide or carry the vacuum cleaner. To operate such a vacuum cleaner, it is necessary that a cable is connected to a power source. After use, this cable is wound up in a receptacle for a cable winding, which is molded onto the upper part. The power plug is positioned outside of the receptacle next to the handle and fixed by a pivoting clamp to prevent independent winding of the cable.

This arrangement requires for the winding and unwinding of the cable by the user targeted cable management for insertion of the cable in the all-round recording on the upper part of the vacuum cleaner. In addition, the fixation of the cable in the receptacle for a cable winding is given only by the gravity of the cable, without any further securing means is provided.

From the WO 2011/015830 A1 Furthermore, a cable receptacle on a top of a vacuum cleaner, which surrounds a handle. Above this U-shaped cable receiving a cover is clipped, which engages adjacent to the handle. This cover covers the opening of the cable receptacle, wherein between the cover and the cable receiving a circumferential gap is provided, which has a width which is greater than the diameter of the cable. As a result, the cable can be easily inserted into the receptacle. However, the cable also gets out of the receptacle again in a simple manner without securing the cable winding to remain in the cable receptacle.

The invention has for its object to develop a cleaning device, in particular a vacuum cleaner with a receptacle for a cable winding, in which simplifies the storage of the cable in a stowed position and the removal of the cable for use and at the same time in the stowage permanent fixation of the cable is given in the recording for the cable winding.

This object is solved by the features of claim 1. Further advantageous embodiments and further developments are specified in the further claims.

By forming at least one projection on a housing portion of the cleaning device, which is associated with the handle, a receptacle for a cable winding is created, in which each individual winding of the cable or the entire cable winding can be inserted in a simple manner at once. The same applies to the removal of the cable. This recording formed between the handle and the projection can be closed by inserting the cable winding in a simple manner by a closure, so that a permanent fixation of the cable winding in the recording and an independent release of the cable is prevented from the recording.

Between the arranged on the housing portion of the cleaning device projection and the handle a U-shaped, upwardly open receptacle is provided. This allows a particularly simple insertion of the cable into the receptacle as well as a removal. In addition, the cable initially remains due to its gravity in the U-shaped receptacle, so that then a simple closing of the recording with the closure is possible.

The U-shaped receptacle is preferably closed by a sliding closure. This allows easy and quick handling. The displaceable closure is preferably designed as a sliding latch and allows easy one-handed operation.

Preferably, the sliding closure is integrated in the handle. This allows the adjacent areas of the housing section to Handle as well as the design and function are maintained without the attachment of a closure causes a structural change.

A preferred embodiment of the invention provides on both sides of the handle in its longitudinal axis in each case a projection which is associated with the handle in each case for forming a receptacle for a cable winding. Trained as a sliding latch closure closes either one of the two shots. As a result, not only a simple handling is given, but there are also two receptacles on a housing portion provided to insert the cable winding, the recordings are locked in particular by a closure. Depending on the selected recording while a larger or smaller loop formation for the cable winding can be selected by the user, so that even longer cables can be safely absorbed.

The arranged on the housing portion handle is connected to two provided on the housing portion sockets, wherein between an upper engagement surface of the handle and the base an opening for guiding the displaceable closure is provided. The closure occurs optically only in the U-shaped recess occluding section and incidentally does not affect the design. At the same time a simple and secure guidance of the closure can be made possible as a sliding bolt by this arrangement.

The slidable closure preferably abuts an underside of the handle and forms part of the lower engagement surface of the handle. For the user, despite the integration of the slidable closure in the handle no impairment when carrying or guiding the cleaning device is given.

Preferably, the displaceable closure is guided in a depression of the attack surface, so that optionally when carrying the cleaning device, the forces transmitted to the closure forces do not affect the function of the closure.

The displaceable closure advantageously has an actuating element protruding from the lower engagement surface of the handle. It may, for example, be an elevation, a rib or a detent. As a result, the displacement movement from a first working position, by which a recording is closed, in a further working position, through which the further recording is closed, easier.

Furthermore, the displaceable closure is preferably arranged secured with a detachable latching connection in a first and a further working position. As a result, an independent release of the closure is prevented from the occupied working position, that is, a once assumed locking position is maintained.

The releasable latching connection is advantageously integrated in an opening in the base. As a result, an arrangement of the closure that is barely visible from the outside can be made possible.

The releasable latching connection is preferably designed as a snap element, spring-loaded latching pin or the like, in particular as a tongue with at least one latching cam arranged thereon. The housing portion of such cleaning devices is usually made of plastic as an injection molded part. This releasable latching connection can be produced in a simple manner integrated with the upper part of the cleaning device as a component.

The upper engagement surface of the handle preferably has a concave contour. The at least one adjacent to the handle arranged projection also has a concave contour on its upper end surface, which is aligned with the engagement surface of the handle. As a result, a bearing surface is created for a suction tube to hang it on it and to allow a secure carrying the suction tube with the cleaning device.
