| 摘要 |
<p>The invention relates to a high-pressure cleaning device (10) comprising a supply connection (34), a pressure connection (35), an electric heating device (26), and a pump (24) which is driven by a motor (23) and which comprises a suction line (67) and a pressure line (68). The suction line (67) can be fed cold cleaning fluid via a first magnet valve (73) and heated cleaning fluid via a second magnet valve (74), and the magnet valves (73, 74) can be controlled by means of a control device (30). The magnet valves (73, 74) can be controlled dependent on a state variable of the cleaning fluid that can be found in the pressure line (68) so that the high-pressure cleaning device (10) is less susceptible to faults and can be produced in a more cost-effective manner.</p> |
