Definitions

  • the invention relates to a high-pressure cleaning device with a motor and a motor-driven pump, which has a pump inlet and a pump outlet, and with a motor and the pump at least partially surrounding housing and with a connectable to the pump outlet pressure hose.
  • a cleaning liquid preferably water
  • the cleaning liquid can be supplied to the pump inlet via a supply line, for example a suction hose, and pressurized by the pump.
  • the pressurized cleaning fluid can be dispensed via the pump outlet.
  • the pressure hose can be connected to the pump outlet.
  • a liquid discharge member such as a spray lance or a spray gun can be connected.
  • the high-pressure cleaner has a variable-length tether, which is arranged on an outer side of the housing, and that the pressure hose in the wound state between the tether and the outside of the housing can be clamped.
  • the pressure hose when not in use, especially for transport and storage purposes, wound up and fixed by means of the tether on an outer side of the housing by being clamped between the tether and the outside.
  • the tether can be changed in length for this purpose.
  • the pressure hose can be removed from the area between the tether and the outside and connected to the pump outlet.
  • the strap can reduce its length to such an extent that it rests directly on the outside of the housing. The size of the housing is therefore virtually unchanged by the provision of the tether.
  • the pressure hose If the pressure hose is to be fixed on the outside, for example for transport or storage purposes, then it can be wound up and clamped between the tether and the housing. In this case, the tether can increase its length, so that it releases the storage space between the tether and the outside of the housing.
  • the tether is elastically extensible.
  • the tether can be stretched so far elastically that the pressure hose between the belt and the outside of the housing can be clamped. Should the pressure hose can be used, it can be removed from the region between the tether and the housing and the tether can contract due to its elasticity again so far that it rests directly on the outside of the housing.
  • the tether can be wound up.
  • a winding device for automatic winding is preferably disposed within the housing and the tether of the winding device, if necessary, that is for clamping the wound Druckschiauchs be unwound in the required for the clamping of Druckschiauchs length, wherein the retaining hose engages through an opening of the housing to get from the arranged inside the housing winding device to the outside of the housing.
  • the tether can in this case counter to an elastic return force of the winding device are removed, so that it is automatically wound up after removal of Druckschiauchs again and automatically applies to the outside of the housing.
  • the tether is designed as a band-shaped textile material. It can be provided, for example, that the tether is made of a fabric or a braid, preferably made of a plastic fabric or a plastic braid. It is particularly advantageous if it is made of an elastically stretchable plastic fabric or plastic braid.
  • the tether has a tear-resistant plastic material.
  • the tether is made of a Elastanmate- rial.
  • a particularly secure transport and storage possibility of the pressure hose is achieved in an advantageous embodiment of the invention thereby aims that the tether is centrally located on an outer side of the housing.
  • the central arrangement of the tether makes it possible to support the wound pressure hose on both sides of the tether on the outside of the housing.
  • the tether extends in a position of use of the high-pressure cleaning device from a lower surface of the housing facing the footprint of the high-pressure cleaning device to an upper area of the housing facing away from the footprint.
  • the tether extends vertically in a position of use of the high-pressure cleaning device from bottom to top.
  • the tether extends on the outside of the housing between a first belt holder and a second belt holder.
  • the tether can be attached to the housing.
  • the pressure hose clamped between the tether and the housing can be supported on a belt holder.
  • the belt support supporting the pressure hose is advantageously arranged adjacent to the lower region of the housing. The risk that the clamped between the tether and the housing pressure hose unintentionally falls down on a footprint of the high-pressure cleaner can be kept low.
  • a first belt holder in the operating position of the high-pressure cleaning device is arranged vertically below a second belt holder.
  • the tether may extend along the outside of the housing from the first strap mount to the second strap mount, and for transport and storage purposes, the wound pressure hose may be clamped between the tether and the housing in the area between the first strap mount and the second strap mount.
  • at least one belt holder is detachable. This makes it possible to detach the tether in the region of at least one belt holder from the housing.
  • the tether can be guided around the wound, positioned on the outside of the housing pressure hose for fixing the pressure hose and then it can be fixed with its free end again on the outside of the housing.
  • both strap holders are detachable. This makes it possible to completely detach the tether from the housing for cleaning purposes, for example. Also, a replacement of a tether due to damage is facilitated by the releasable design of the two belt mounts.
  • At least one belt holder in an advantageous embodiment of the invention, has a first connecting element arranged on the housing, which can be detachably connected to a second connecting element arranged on the holding belt.
  • the first connecting element is preferably integrally connected to the housing.
  • the first connecting element forms a one-part plastic molded part together with the housing.
  • the second connecting element may be detachably or permanently connected to the tether.
  • the second connecting element is sewn to the tether, glued or screwed.
  • the first connecting element with the second connecting element is releasably latched.
  • the two connecting elements have in such a configuration cooperating with each other latching elements.
  • one the two connecting elements has a latching recess into which the latching element of the other connecting element can be latched.

  • the second connecting element may, for example, have a hook-and-loop fastener. This gives the possibility in a structurally simple way to fix the end portion of the tether looping around the loop of the first connecting element by means of the hook-and-loop fastener on the tether.
  • the first connecting element can be screwed to the second connecting element.
  • the first connection element can for example form a holding web with at least one bore having an internal thread.
  • the tether may loop around the holding web with one end section and be screwed to the holding web by means of a screw.
  • a particularly simple handling of the tether is achieved in an advantageous embodiment of the invention in that the second connecting element can be suspended in the first connecting element.
