Zusammenfassung:	A dynamic-pressure measuring system for an electronic speed regulation of the drive motor has to be integrated in tubs made of plastic for abovementioned washing machines. The relation between the dynamic pressure occurring during spinning and the water or foam in the tub serves for regulating the spinning speed. This method has hitherto been applicable only in front-loading washing machines having special-steel tubs. A retaining chamber (2) with a flow-off connection (3) is formed at the lowest point of a plastic tub (1). A skirt (5) and connection piece (4) pointing rearwards at rightangles for a pressure-measuring device are located within the retaining chamber (2). During spinning, water/lye is forced into the retaining chamber (2), and the fluctuating dynamic pressure occurring at the connection piece (4) is converted into signals via pressure sensors and fed to an electronic speed-regulating circuit. The top-loading washing machine is suitable mainly for households with confined conditions of space.
