Abstract
The present invention discloses a water purifier and a water production method thereof, relating to the technical field of water processing, the water purifier comprising: a reverse osmosis membrane device comprising a raw water port, a purified water port and a waste water port; a water storage device which is provided therein with a first chamber of which a volume can be adjusted, the first chamber being communicated with the raw water port and the purified water port, respectively; in the cleaning mode, the first chamber is disconnected from the purified water port, the first chamber is communicated with the raw water port, and the purified water flows into the first chamber from the raw water port of the reverse osmosis membrane device and is discharged from the waste water port of the reverse osmosis membrane device; in the water production mode, and the first chamber is communicated with the purified water port, the first chamber is disconnected from the raw water port. In the present invention, the purified water is stored in the water purifier so as to flush the reverse osmosis membrane device, such that the total dissolved solid (TDS) of a first glass of purified water that flows out of the water purifier at the beginning of use is reduced, and meanwhile lifetime of a reverse osmosis membrane in the reverse osmosis membrane device is effectively improved.
