The invention relates to a high-pressure cleaning appliance comprising a first functional device required for operation in the form of a heatable heat exchanger for heating a liquid that is dischargeable from the high pressure cleaning appliance, and at least one further, second functional device required for operation which is arranged below the heat exchanger. In order to develop such a high-pressure cleaning appliance such that it is more user friendly to maintain, the invention proposes that the high-pressure cleaning appliance comprise a first appliance unit having a carrying device on which the heat exchanger is held, and a second appliance unit having a support device on which the at least one second functional device is held, and that the carrying device be releasably connectable to the support device in a force-locked and/or positively-locked manner.

High-pressure cleaning appliance

The invention relates to a high-pressure cleaning appliance, comprising a heatable heat exchanger for heating a liquid that is dischargeable by the high-pressure cleaning appliance, a motor having a drive shaft that defines a drive axis, a pump unit for increasing the liquid pressure, a blower wheel for generating a combustion air flow, and a fuel pump for delivering a fuel to the heat exchanger, wherein the pump unit, the blower wheel, and the fuel pump are disposed along the drive axis and are drivable by means of the drive shaft and form an assembly together with the motor. In order to fit the assembly to the appliance in a simplified manner while achieving a more compact design for appliance, the appliance comprises a half-shell housing having a first half-shell and a second half-shell which between them define an accommodating chamber in which the assembly is at least partially accommodated.

In order to improve a high-pressure cleaning apparatus comprising a pump unit adapted to be driven by motor, a first connection element for detachable connection to a liquid supply conduit, said first connection element being connected to the suction side of the pump unit, and a second connection element for detachable connection to a high-pressure conduit, said second connection element being connected to the pressure side of the pump unit, such that it can be handled in a more user-friendly manner, the invention proposes that the first connection element and/or the second connection element be oriented in a direction facing upward away from a supporting surface for the high-pressure cleaning apparatus.

High-pressure cleaning apparatus

The invention relates to a high-pressure cleaning appliance, comprising a heatable heat exchanger for heating a liquid that can be discharged by the high-pressure cleaning appliance, a motor having a drive shaft that defines a drive axis, a pump unit for increasing the liquid pressure, a blower wheel for generating a combustion air flow, and a fuel pump for delivering a fuel to the heat exchanger, wherein the pump unit, the blower wheel, and the fuel pump are disposed along the drive axis and can be driven by means of the drive shaft and form an assembly together with the motor. In order to improve such a high-pressure cleaning appliance in such a manner that it has a more compact construction and a smaller space requirement, the assembly of the high-pressure cleaning appliance according to the invention, with regard to a height direction thereof, is disposed below the heat exchanger.

The invention relates to a high-pressure cleaning appliance, comprising a heatable heat exchanger for heating up a liquid dispensable by the high-pressure cleaning appliance, a blower with a flow channel connected thereto for supplying combustion air to the heat exchanger, and a setting member for setting the amount of combustion air suppliable to the heat exchanger, the setting member having a channel constriction section which is positionable in the flow channel and movable relative thereto for changing the free cross-sectional area of the flow channel. In order to develop a generic high-pressure cleaning appliance further so that the amount of combustion air suppliable to the heat exchanger can be better adjusted, it is proposed that the channel constriction section be configured so as to be slidingly displaceable relative to the flow channel.
