Water purification system and flushing method thereof

Abstract

The invention provides a water purifying system and a flushing method thereof. The water purifying system comprises a water purifying branch, and a water inlet switch, a first water pump, a filtering device and a pressure barrel are sequentially connected to the water purifying branch in series. The water purifying system further comprises a flushing return pipeline and a water storage device, a first end of the flushing return pipeline is communicated with the first pressure barrel, a second end of the flushing return pipeline is connected between the water inlet switch and the first water pump, and the water storage device is connected between the water inlet switch and the first water pump in series. As the flushing return pipe and the water storage device are arranged, in the flushing process, water in the pressure barrel and the water storage device can be pressurized by the first water pump to flush a filter core, it can be ensured that a filtering device is flushed at high pressure with high flow, flushing is not affected by water inlet pressure and flow, the flushing effect is ensured, the service life of the filtering device is prolonged, and reliability is improved. In addition, water, needing to be drained due to long-term nonuse, in the pressure barrel can be used repeatedly, and the water resource is saved.

Description

technical field [0001] The invention relates to the field of water purification systems, in particular to a water purification system and a flushing method thereof. Background technique [0002] In the prior art, the general water purifier uses tap water to flush the RO membrane filter element. When the tap water pressure or flow is not enough, the flushing effect is poor, and the life of the RO membrane will be affected after a long time; in addition, when the water purifier is not used for a long time , The water in the pressure tank is generally released to prevent the growth of bacteria from affecting human health, and separate water is required for flushing, both of which will cause waste of water resources. Contents of the invention [0003] The invention aims to provide a more reliable water purification system and flushing method thereof. [0004] The invention provides a water purification system, which includes a water purification branch road, on which a water ...
