    • In a water-bearing household appliance with a liquid container filled through a valve in a liquid feed line, and in which a liquid filling level is detected for monitoring at least one safety level of a safety device, the safety device includes an optical light guidance system for reflecting a light beam by which the filling level is detected with the aid of a change in the reflection response on at least one reflecting site and is used to monitor the safety level. As an optical light guidance system, the safety device offers the advantage of dispensing with moving mechanical components—for example, a float, a level switch, an operating lever, an operating rod, etc.—to reduce the risk of mechanical defects that are associated with a substantial outlay on repair time and costs to a minimum or to completely eliminate the risk.
    • 在具有通过液体供给管线中的阀填充有液体容器并且其中检测到液体填充液位以监测安全装置的至少一个安全级别的含水家用电器中,所述安全装置包括光学引导 系统,用于借助于至少一个反射部位上的反射响应的变化反射检测到填充水平的光束,并用于监视安全等级。 作为光学引导系统,安全装置具有分配移动的机械部件(例如浮子,液位开关,操作杆,操作杆等)的优点,以减少机械缺陷的风险 将维修时间和成本的大量费用降至最低,或完全消除风险。
