Abstract

The invention discloses a water purifier and a control method. The water purifier comprises a filtering mechanism, wherein the filtering mechanism is provided with a raw water inlet, a filtered wateroutlet and a wastewater outlet; a flushing mechanism communicated with the raw water inlet, wherein the flushing mechanism can flush a filtering mechanism; a recycling mechanism communicated with thewastewater outlet, wherein the recycling mechanism can recycle and store water discharged from the wastewater outlet when the filtering mechanism is flushed. According to the water purifier and the control method provided by the invention, the TDS of water discharged when the water purifier is started can be effectively reduced, and the water efficiency of the water purifier is improved.

Description

technical field [0001] The present application relates to the field of water purification, in particular to a water purifier and a control method. Background technique [0002] For existing water purifiers, especially large-flow bucketless water purifiers, the raw water flowing in from the raw water inlet is filtered through the reverse osmosis membrane device during use, the filtered water flows out from the filtered water outlet, and the waste water is discharged from the waste water outlet. When the water purifier is not in use, the concentrated wastewater has been staying on the wastewater side of the reverse osmosis membrane that acts as a filter in the reverse osmosis membrane device. When the time reaches a certain level, the salt or other dissolved solids in the wastewater will be released. Permeates the reverse osmosis membrane and then reaches the filtered water side of the reverse osmosis membrane. In this way, when the water purifier is in use again, the total d...
