Definitions

  • the invention relates to a high-pressure cleaning device, comprising a heatable heat exchanger for heating a dispensable from the high-pressure cleaner fluid, a motor with a drive shaft defining a drive shaft, a pump unit to increase the fluid pressure, an impeller for generating a combustion air flow and a fuel pump to promote a fuel for the heat exchanger wherein the pump unit, the impeller and the fuel pump are arranged along the drive axis and driven by the drive shaft and form together with the motor a unit.
  • Such a high-pressure cleaner is in the DE 36 17 556 A1 described, in which the unit is installed upright with vertically oriented drive axle next to a likewise upright heat exchanger with vertically aligned axis. Due to this design, the high-pressure cleaner on a not inconsiderable amount of space, in particular it requires a considerable footprint.
  • the high pressure washer also has an upright vertical axis aligned heat exchanger. Laterally next to the heat exchanger, a horizontal axis-oriented motor pump unit comprising an electric motor and a drivable by this high-pressure pump is arranged.
  • the DE 93 03 648 U1 describes a high-pressure cleaning device according to the preamble of claim 1, which comprises a horizontally mounted horizontally mounted heat exchanger. Above the heat exchanger is a motor pump unit comprising an electric motor and one of these drivable High-pressure pump arranged as well as a motor driven by the fan and a motor driven fuel pump.
  • the horizontal installation of the heat exchanger also requires a considerable amount of space, so that the high-pressure cleaner claims a considerable footprint.
  • a cleaning device which has a motor-driven pump unit and a provided with wheels tube frame.
  • the tubular frame is constructed of several relatively pivotable segments, so that it can be folded. This makes it possible to store the cleaning device hanging in a space-saving manner.
  • Object of the present invention is to develop a generic high-pressure cleaner so that it has a more compact design and a smaller footprint.
  • the high-pressure cleaning device on the one hand, a compact design can be achieved in that the motor is used to drive the pump unit, the fan wheel and the fuel pump. For this reason, it is not necessary to provide separate drives for the pump unit, the impeller and the fuel pump.
  • the structural unit is arranged below the heat exchanger. This allows, for example, supporting components of the high-pressure cleaning device, such as a Chassis to make smaller than in the known from the prior art high-pressure cleaning devices. Also parts of a possible cladding can be made smaller, so that overall results in a more compact design and a smaller space requirement of the high-pressure cleaner.
  • the high-pressure cleaner according to the invention claimed a smaller footprint.
  • the high-pressure cleaner comprises an upright heat exchanger with an axis aligned in the vertical direction. In this way, only a small footprint engaging high-pressure cleaner can be built. Conveniently, during operation, the axis of the heat exchanger is vertically aligned to improve the stability of the high-pressure cleaner.
  • the drive axle is aligned horizontally. As a result, the space required for the high-pressure cleaner can be reduced. Furthermore, in this embodiment, it is possible to shift the center of gravity of the high-pressure cleaning device downwards relative to an embodiment in which the drive axle is oriented vertically, for example.
  • the high-pressure cleaner is more stable in this way, which can reduce the requirements for supporting parts of the high-pressure cleaner. This in turn has a favorable effect on a compact design of the high-pressure cleaning device.
  • the high-pressure cleaning device has at least one pair of rotatable wheels about a common axis of rotation, parallel to which the drive axis is aligned.
  • the high-pressure cleaner can be moved on a footprint. It can be provided in particular that the high-pressure cleaning device can be tilted about the contact points of the wheels on the footprint and can be transported similar to a sack truck.
  • the orientation of the drive axis has parallel to the axis of rotation proved in practice to be advantageous for the stability of the high-pressure cleaner.
  • the heat exchanger has an axis, based on the longitudinal direction of the high-pressure cleaner, between the axis of rotation of the wheels and the drive axle is arranged.
  • the high-pressure cleaning device comprises a chassis, on which the structural unit is held, as well as a support means, at least partially covering it, on which the heat exchanger is held.
  • the assembly may be connected to the chassis and the heat exchanger may be connected to the support get connected. Subsequently, the support means with the chassis, for example, non-positively and / or positively connected.
  • the support means with the chassis is detachably connectable, because this favors in addition to a simplified installation of the high-pressure cleaner and its simplified maintenance.
  • the carrying device can be detached from the chassis in just a few steps and completely or largely without the use of tools.

  • the support device has a plate-shaped ausgestaltetes support member with a footprint for the heat exchanger.
  • the support member of the heat exchanger can be steadily mounted, and the support member may be fixed, for example, on the chassis arranged support elements.
  • Below the support member is advantageously a receiving space available in which the assembly is at least partially arranged. After loosening the support member from the chassis then the assembly or optionally a covering this cover is freely accessible to a user.
  • the motor or a unit of motor and pump unit is arranged on a central longitudinal axis of the high-pressure cleaning device.
  • the stability of the high-pressure cleaning device can be increased because the engine or the unit of the engine and pump unit occupy most of the mass of the assembly.
  • the pump unit forms a first end of the structural unit in the axial direction, relative to the drive axle. This is advantageous, for example, during maintenance of the high-pressure cleaning device, for example when maintenance work is to be carried out on a supply line for pressurized liquid and / or on a discharge line for pressurized liquid which is held on the pump unit.
  • the pump unit is easier for the user to achieve in this embodiment.
  • the pump unit projects at least partially beyond an outer boundary of the heat exchanger. This also facilitates a user to reach the pump unit, for example, for maintenance.
  • the high-pressure cleaning device comprises a fan wheel arranged along the drive axis and drivable by the drive shaft for generating a cooling air flow which cools the engine as part of the structural unit.
  • a cooling air flow for the engine can be provided so that its overheating can be avoided.
  • the fan is driven by the motor, it is not necessary to provide a separate drive for the fan. This favors a compact design of the high-pressure cleaner.
  • the fan is the motor, relative to the drive axle, held axially upstream on the drive shaft. It can be configured in particular as an axial fan.
  • the pump unit is arranged on the side facing away from the fan of the motor, because this gives the possibility of using the cooling air flow not only to cool the engine, but also the pump unit.
  • the fan wheel is arranged on the side of the fan wheel facing away from the motor.
  • a combustion air flow is generated for the heat exchanger. Due to the fact that the fan wheel is axially upstream of the fan wheel, relative to the drive axle, it is largely avoidable for the combustion air to comprise air heated up solely as a result of waste heat from the engine. This has proven to be advantageous in practice for the operation of the heat exchanger.
  • the fan wheel projects at least partially beyond an outer boundary of the heat exchanger and when the high-pressure cleaning device has a flow channel for combustion air outgoing from the fan and pointing in the direction of the heat exchanger.
  • the flow channel can be given a simple design. For example, it can extend straight from the impeller in a vertical direction.
  • the heat exchanger preferably has a housing jacket with an inlet opening for combustion air arranged at its side facing the blower wheel, to which the flow duct is connected approximately tangentially to the housing jacket to the heat exchanger.
  • the combustion air flow can thereby enter with approximately tangential flow direction in the housing of the heat exchanger, which has proven in practice in the operation of the heat exchanger to be advantageous.
  • the fuel pump in the axial direction forms a second end of the assembly, because it is easier for a user to achieve, for example during maintenance of the high-pressure cleaning device.
  • fuel lines are to be connected to or detached from the fuel pump, which can be carried out in a simpler manner in this embodiment.
  • the fuel pump projects at least partially beyond an outer boundary of the heat exchanger.
  • the high-pressure cleaner above the fuel pump comprises a tank for fuel.
  • a tank for fuel This allows a fuel line connecting the tank to the fuel pump to be as short as possible.
  • the tank can be arranged, for example, next to the heat exchanger.
  • the high-pressure cleaning device has a half-shell housing with a first half-shell and a second half-shell, which define between them a receiving space in which the structural unit is at least partially received.
  • a half-shell housing with a first half-shell and a second half-shell, which define between them a receiving space in which the structural unit is at least partially received.
  • This favors on the one hand a compact design of the high-pressure cleaning device, in which the structural unit is at least partially accommodated in the receiving space.
  • half-shell housing for example, it can be kept as a whole. It then does not require a separate fixation of the individual components, ie the motor, the pump unit, the impeller, the fuel pump and possibly the fan.
  • the installation of the high-pressure cleaning device is simplified.
  • the assembly is to be inserted into the first half-shell and is at least partially covered with the second half-shell, which on the first half shell is fixed. Furthermore, the use of the half-shell housing allows protection of the assembly, which is at least partially included in this.
  • the fuel pump and / or the pump unit are at least partially disposed outside of the half-shell housing.
  • a simple structural design receives the high-pressure cleaning device, if it comprises a chassis that configured the first half-shell and / or the second half-shell.
