A heatable high pressure cleaning appliance is provided with an undercarriage and a housing lower part, arranged on the undercarriage, in which a motor and a pump driven by the motor for pressurizing water are arranged, and with a fuel-operated heat exchanger for heating the water and a fuel tank for storing liquid fuel for the heat exchanger. In order to further develop the heatable high pressure cleaning appliance in such a way that it has a high mechanical stability and is producible in a cost-effective manner, it is proposed that the fuel tank is configured as a one-piece plastic hollow body, which forms the housing lower part and is held on a rigid support frame, wherein the support frame forms a shock protector that at least partially surrounds the fuel tank in the circumferential direction.

A coupling arrangement for a screw coupling for liquid conduits of a high-pressure cleaning apparatus is provided. The coupling arrangement includes a plug part which is pluggably connectable to a complementarily configured plug part of a second coupling arrangement of the screw coupling for establishing a liquid-tight and releasable connection therewith with a sealing ring interposed therebetween, and a connecting part having a thread that is screwably connectable to a complementarily configured thread of the second coupling arrangement. The thread can be of multiple-threaded configuration and the connecting part can include a clamping element which is aligned in an in-line relationship with the thread relative to the thread longitudinal axis and is releasably clampable against a complementarily configured clamping element of the second coupling arrangement by axially inserting one into the other.

A heatable high-pressure cleaning device () is provided with a fuel-operated heat exchanger () and a fuel tank () which has a tank upper section () with a closable filling opening () and a tank lower section () forming the base () of the fuel tank (). In order to develop the heatable high-pressure cleaning device () further in such a manner that it can be produced more inexpensively and have a longer service life, the tank upper section () can be connected to the tank lower section () in a materially joined manner via a join area () and the fuel tank () can be fillable with liquid fuel only up to beneath the join area () in a horizontal position of use of the high-pressure cleaning device ().

A system for storing and dispensing a liquid cleaning additive for a high-pressure cleaning appliance has a device for storing the cleaning additive and a device for dispensing the cleaning additive in a controlled manner. In order to develop the system such that it is easier to handle, it is proposed that the storage device has an intermediate tank, which is fixedly held on the high-pressure cleaning appliance, and an independently handlable refill container for filling the intermediate tank, it being possible for liquid cleaning additive to be withdrawn in a controlled manner from said intermediate tank by means of the dispensing device, it being possible for the refill container to be secured on the high-pressure cleaning appliance and to be flow-connected to the intermediate tank, cleaning additive flowing automatically out of the refill container into the intermediate tank upon withdrawal of cleaning additive from the intermediate tank, in order to maintain a predetermined liquid level in the intermediate tank. A refill container for such a system and also a high-pressure cleaning appliance having such a system are also proposed.

A centrifugal fan with a pot-like impeller and with a housing, having a first circumferential wall region with an arc-like curvature which extends directly along the impeller. The housing includes in a direction of rotation of the impeller a second circumferential region with a radial distance from the impeller increasing spirally up to an outlet region. The housing includes in an opposite direction a third circumferential wall region extending to the outlet region, having an S-curvature and including a sub-region curved in the same direction as the first circumferential wall region forming a flow baffle element. Two side walls cover the axial end faces of the impeller wherein one of the side walls extends into the pot-like impeller and divides its interior into a first suction chamber having an intake and a second suction chamber. The outlet region expands in cross-section in the outlet flow direction.

A cleaning apparatus, in particular a high-pressure cleaning apparatus, is provided, on which at least one fastening device for fastening the cleaning apparatus to a carrier is disposed. The at least one fastening device comprising at least one tensioning section on which a tensile force, which is directed at the carrier, acts when the cleaning apparatus is fastened to the carrier by means of a tensioning element. At least one retaining section is connected to the at least one tensioning section, for retaining the at least one fastening device on the cleaning apparatus. The at least one fastening device has at least one support section in order to be supported on the cleaning apparatus. The support section is connected to the at least one tensioning section by at least one connecting section, the at least one connecting section yielding if the tensile force exceeds a maximum permissible tensile force.

In a closure device for the fluid delivery line of a high-pressure cleaning apparatus having arranged in the fluid delivery line a closure member which is pressed with a closing force against a valve seat and thereby closes the fluid delivery line, and which is liftable off the valve seat by a mechanical actuating element displaceable by a hand lever and extending in a sealed manner out of the fluid delivery line, when the hand lever is moved in the direction of an open position, in order to reduce the holding forces when the hand spray gun is open, it is proposed that downstream of the valve seat in the fluid delivery line a displaceably mounted piston extend in a sealed manner out of the fluid delivery line and upon being pushed out of the fluid delivery line cooperate with the hand lever in such a manner that the hand lever is moved in the direction towards its open position.
