Abstract: A high-pressure cleaning appliance is provided, including a housing having a motor and a pump, driven by the motor, arranged therein, and including at least two rotatably mounted running wheels, a push bar movable back and forth between a parking position and an operating position, and a locking device for releasably locking the push bar, the locking device including an actuating member which is coupled by at least one coupling member to at least one locking member which interacts with the push bar and is movable from a locking position to a release position by actuating the actuating member. So that the high-pressure cleaning appliance can be assembled more cost-effectively and more easily, the locking device includes a prefabricated constructional unit which forms the actuating member, the at least one coupling member and the at least one locking member and is movably mounted on or in the housing.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: The invention relates to a method of decorating hard materials, especially materials which can be fired for the purpose of decoration, by means of direct or indirect printing. Printing is carried out by means of inkjet technology. According to the invention, a colour paste containing at least 30 wt. % inorganic solids, such as pigments and glass frits, and a thermoplastic medium having a melting point of at least 30° C. is applied to the surface to be decorated by means of a heatable inkjet print head, which preferably additionally has a device for circulating the molten colour paste.
