Abstract
A pressure washer (1) includes a main line (5) through which liquid can be delivered by a high-pressure pump (3), a control element (42) with which the size of a liquid volume flow of the liquid in the main line (5) can be influenced on the basis of a control signal generated by the control element (42), and a mixing device (80) with which the liquid can be fed an additive (81) with an additive volume flow. The mixing device (80) sets the size of the additive volume flow on the basis of the control signal.
Claims16
A pressure washer, comprising:
- a high-pressure pump (3);
- a main line (5) configured to deliver a liquid from the high-pressure pump (3);
- a control element (42) configured to generate a control signal and thereby influence a liquid volume flow rate of the liquid in the main line (5);
- and
- a mixing device (80) configured to supply an additive (81) to the liquid at an additive volume flow rate,
- wherein the mixing device (80) is configured to set the additive volume flow rate based on the control signal.
A method for operating a pressure washer, wherein the pressure washer (1) comprises
- a high-pressure pump (3),
- a main line (5) configured to deliver a liquid from the high-pressure pump (3);
- a control element (42) configured to generate a control signal and thereby influence a liquid volume flow rate of the liquid in the main line (5), and
- a mixing device (80) configured to supply an additive (81) to the liquid at an additive volume flow rate,
- the method comprising:
- setting both the liquid volume flow rate and the additive volume flow rate based on the control signal.
