    • The invention is directed to a process for the operation of a washing machine (1) with a tub (2) containing a drum (3) for receiving laundry (4) and a pressure sensor (6) in contact with an aqueous liquid, a drive motor (5) for the drum (3), a pump (18), and a control unit (8), wherein the presence of foam can be detected by a pressure change, characterized in that the following steps are carried out:
      (a) a washing phase is conducted with a suds containing water and detergent;
      (b) water is added during or after the washing phase (a) into the tub (2) in an amount Q ≤ Q set , wherein Q set is a prescribed maximum quantity of water to be added in this step;
      (c) a change of the pressure P is measured by the pressure sensor (6) upon the addition of the water in step (b); and
      (d) the pressure change ΔP measured in step (c) is evaluated with respect to the presence of foam.
      The invention is moreover directed to a washing machine (1) in which this process can be conducted.
    • 本发明涉及一种用于洗衣机(1)的操作的方法,所述洗衣机具有盛放用于接收衣物的滚筒(3)的桶(2)和与含水液体接触的压力传感器(6) 用于滚筒(3)的驱动马达(5),泵(18)和控制单元(8),其中泡沫的存在可以通过压力变化来检测,其特征在于执行以下步骤: a)用含有水和洗涤剂的泡沫进行洗涤阶段; (b)在洗涤阶段(a)期间或之后将水以Q≤Qset的量加入桶(2)中,其中Qset是在该步骤中加入的规定的最大水量; (c)在步骤(b)中加入水时通过压力传感器(6)测量压力P的变化; 和(d)在步骤(c)中测量的压力变化ΔP关于泡沫的存在进行评估。 此外,本发明涉及一种可以进行该过程的洗衣机(1)。
