Abstract
The invention relates to a mixing apparatus () with a main line (), in which a liquid (F) flows along a direction of flow (FR), and a secondary line (). The main line () has an inlet (), an outlet () for discharging the liquid (F) conducted through the main line (), and a three-way valve () at a beginning () and at an end (). The secondary line () is connected via the three-way valves () to the main line () and, together with the main line (), forms a mixing circuit (MKL). The liquid (F) can be pumped with a pump () through the main line () and through the secondary line () in the mixing circuit (MKL). In addition, at least one additive inlet opening () is provided on the main line () for adding an additive into a mixing zone (M) of the main line (). The mixing apparatus () furthermore has at least one swirling means () in the main line (). The invention moreover relates to a washing machine having such a mixing apparatus () and to a method for intermixing an additive with a liquid (F).
