Embodiment Construction

[0021] Figure 1 depicts a washing machine according to an embodiment of the invention with a drum 13 in which laundry 14 is located. The drum 13 is driven by an electric motor 15 with a belt drive. The lye container 17 is arranged below the drum 13 , or rather surrounds it, and also has a drain 18 leading to the pump 20 . The pump 20 delivers the water in the lye container 17 to the outside of the washing machine 11 through the drain hose 21 . In order to heat the water or floating matter in the lye container 17 , a heating device 23 protrudes into the lye container 17 . The water inlet pipe for injecting fresh water and water mixed with detergent is not shown in Fig. 1, but it can be made to match the washing machine according to the prior art.

[0022] The conductivity sensor 24 protrudes into the lye container 17 and, in the exemplary embodiment shown, is located close to the heating device 23 , as is known for example from DE 10 2005 007 935 . It can be said that the co...

Abstract

A washing machine (11) is constructed with a special control unit (26) and a conductance sensor (24) in a washing liquid container (17) for detecting a water level (25) including whether there the water is above or below a given water level (25), and the presence of foam during a washing cycle. The control unit (26) controls the operation of a pump (20), as well as the addition of fresh water, for eliminating excessive foam in the washing liquid container (17) and in the drum (13). It is also possible to stop the pump from discharging this disturbing foam (13).

Description

technical field [0001] The invention relates to a method for controlling the operation of a washing machine, in which a conductivity sensor is arranged in the lye container of the washing machine. Background technique [0002] It is known, for example, from DE 10 2005 007 935 A1 or EP 633 342 A1 to control the operation of washing machines in which a conductivity sensor is arranged inside the lye container, for example in the lower region. The measured value of this conductivity sensor is detected and analyzed by the controller of the washing machine. However, the options for further processing or utilization of the measured values ​​mentioned here are limited. Contents of the invention [0003] The object of the present invention is to provide a method of the type mentioned at the outset, by means of which the functionality of the washing or operating method of the washing machine or the analysis of the aforementioned conductivity sensor is improved. [0004] This objec...
