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.
