    • 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.
    • 本发明涉及一种高压清洗器具,其特征在于,包括:可加热热交换器,用于加热由高压清洁器具分配的液体;鼓风机,具有与其连接的流动通道,用于向热交换器供应燃烧空气;以及设定 用于设定可供给热交换器的燃烧空气量的构件,该固定构件具有通道收缩部分,该通道收缩部分可定位在流动通道中并且可相对于其流动,以改变流动通道的自由横截面积。 为了进一步开发通用的高压清洁器具,可以更好地调节可供给热交换器的燃烧空气的量,因此,提出通道收缩部分能够相对于流动通道滑动地移动 。
