Patent ID: 8555902

Claim:
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 an 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 a free cross-sectional area of the flow channel, the channel constriction section being configured so as to be slidingly displaceable relative to the flow channel, a locking device for releasably locking the channel constriction section relative to the flow channel, a setting device for enabling displacement of the channel constriction section when the locking device is in a release position, the setting device comprising a setting section coupled to the channel constriction section, the setting section comprising a plurality of setting elements, the plurality of setting elements each having a contact surface oriented transversely to a direction of displacement of the channel constriction section and being spaced from one another along the direction of displacement of the channel constriction section, and the setting section being located outside of the flow channel.
