Water purifier control method and water purifier

Abstract

The invention discloses a water purifier control method and a water purifier. The control method comprises the following steps: establishing a first cleaning pathway for communicating the scale inhibiting mechanism of a water purifier and a RO membrane member, washing the RO membrane member by the scale inhibiting mechanism for a first preset time through the first cleaning pathway; establishing an evacuating pathway that is connected to the scale inhibiting mechanism, evacuating the fluid in the scale inhibiting mechanism through the evacuating pathway; establishing a second cleaning pathway that is communicated with raw water, and washing the RO membrane member by raw water for a second preset time through the second cleaning pathway. The method also comprises the following steps: establishing a water producing pathway that is communicated with raw water, and producing pure water through the water producing pathway. The provided water purifier control method and water purifier can effectively avoid the phenomenon that the scaling agent in the scaling mechanism is in a dissolved state and the consumption of scaling agent is too fast.

Description

technical field [0001] The present application relates to the field of water purification, in particular to a control method of a water purifier and the water purifier. Background technique [0002] The problem of drinking water is the most concerned issue of the people. It is an indisputable fact that there are many substances that are not conducive to health in the water. This is also the main reason why people's awareness of healthy drinking water has been strengthened, and it is also the root of the hot water purification equipment market. There are many harmful substances in the water, such as sediments, oxides, suspended solids and various harmful bacteria and other impurities. If not treated, drinking for many years may have an impact on health. Water purification is not thorough enough and consumes a lot of energy. [0003] In order to solve the above drinking water problem, reverse osmosis water purifiers (RO water purifiers) are widely used to purify raw water. T...

Problems solved by technology

[0004] However, at present, the antiscaling mechanism in the water purifier is in the state of being immersed in water for a long time, and the antiscalant in the antiscaling mechanism will be dissolved in the water, and as the soaking time prolongs, the antiscaling agent will be in a long-term state. Consumed too quickly during dissolution, which requires frequent replacement of scale inhibitors, increasing costs

[0005] In addition, with the dissolution of the antiscalant and the action of time, some ions in the antiscalant may permeate to the pure water side of the RO membrane, resulting in the problem of excessive drinking water ions, which poses risks to the health of users
