Pulse washing method of reverse osmosis membrane of water purifier

Abstract

The invention discloses a pulse washing method of a reverse osmosis membrane of a water purifier, and relates to the technical field of water purifiers, domestic drinking machines and commercial drinking machines. The pulse washing method comprises the following steps: when an electric control plate of the water purifier receives a washing reverse osmosis membrane instruction from the water purifier, controlling a washing electromagnetic valve to wash the reverse osmosis membrane in an interval working mode through the electric control plate, namely washing for a certain time, stopping washing, washing again, stopping washing, and repeating the operation until the accumulated washing time reaches a set value. As the washing operation is implemented in an interval manner in the method, the water pressure to the reverse osmosis membrane is increased within each small section of the washing time, the washing water amount and the washing time are reduced on premise that an original washing effect is maintained, the resource is saved, the use cost is lowered, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of water purifiers, household direct drinking machines, and commercial direct drinking machines, in particular to a pulse flushing method for reverse osmosis membranes of water purifiers. Background technique [0002] Generally, the method of flushing the reverse osmosis membrane surface of reverse osmosis water purifier / direct drinking machine products is to open the flushing valve for continuous flushing for a period of time, such as: open the flushing valve and flush continuously for 18 seconds. This continuous flushing method has the following disadvantages: [0003] a. Continuous flushing is a serious waste of water. For example, a conventional 50-gallon reverse osmosis water purifier in the market flushes for 18 seconds to produce about 500mL of concentrated water; [0004] b. After the initial moment of continuous flushing, the water pressure on the surface of the reverse osmosis membrane drops, which...
