Automatically controlled washing machine with overflow protection |
摘要 |
An automatically controlled washing machine includes a washing liquid circulation system which drains washing liquid from the bottom of a laundry treatment space and, via a supply orifice, supplies the washing liquid again to the laundry treatment space. The supply orifice is configured such that a dynamic pressure is present in the circulating line during a pumping operation. The washing liquid circulation system has a sensor device which is sensitive to the dynamic pressure and transmits a signal for controlling a supply valve for fresh water as a function of the dynamic pressure. The sensor device also detects a static pressure present in the laundry treatment space and in the circulating line, when the circulating pump is switched off. The sensor device transmits a signal for executing safety measures when the static pressure exceeds a given safety level so that the washing machine is protected against overflowing.
