The invention discloses a household wastewater filtering device. The device comprises a water storage tank, a wastewater inlet pipe, a tap water pipe, a filter, an overflow pipe, a tap water inlet pipe and a normally-closed electromagnetic valve, wherein a water inlet of the normally-closed electromagnetic valve communicates with the tap water inlet pipe, a flushing head communicates with the normally-closed electromagnetic valve, a water level sensor is installed on the filter, a relay is installed in the water storage tank, the water level sensor is connected into an input loop of the relay, the normally-closed electromagnetic valve is connected into an output loop of the relay, an inverted U-shaped pipe is mounted in the water storage tank, one end of the inverted U-shaped pipe communicates with the overflow pipe, and the other end of the inverted U-shaped pipe communicates with the inner bottom of the filter. According to the household wastewater filtering device, when a filter screen is blocked and the water level in a filter barrel rises, due to the effect of the inverted siphon, waste water is discharged out of the water storage tank, the water level drops, the input loop of the relay is connected, the normally-closed electromagnetic valve is opened, and water in the tap water pipe flows to the flushing head through the normally-closed electromagnetic valve to flush the filter screen.
一种家庭废水过滤装置，包括储水箱、废水进水管、自来水管、过滤器、溢流管、自来水进水管、常闭型电磁阀，常闭型电磁阀进水口与自来水进水管连通；安装冲洗头与常闭型电磁阀连通，在过滤器上安装一水位传感器，在储水箱内安装一继电器，水位传感器接入继电器的输入回路，常闭型电磁阀接入继电器的输出回路；在储水箱内安装一倒置U型管，倒置U型管一端连通于溢流管，另一端连通于过滤器内底。当过滤网堵塞，过滤桶内水位上升，由于倒虹吸的作用，废水排出储水箱，水位下降，继电器的输入回路接通，常闭型电磁阀开启，自来水管内的水通过常闭型电磁阀，流向冲洗头，对过滤网进行冲洗。
