Control method for water purifier and water purifier

Abstract

The invention discloses a control method for a water purifier and the water purifier. The control method comprises the following steps: establishing a first cleaning passage for communicating a scale inhibition mechanism of the water purifier and an RO membrane element, and enabling the scale inhibition mechanism to clean the RO membrane element for a first preset time through the first cleaning passage; establishing an emptying passage for connecting the scale inhibition mechanism, and emptying liquid in the scale inhibition mechanism through the emptying passage; establishing a second cleaning passage for communicating raw water, and cleaning the RO membrane element for a second preset time by virtue of the raw water through the second cleaning passage. The method further comprises the following steps: establishing a water production passage for communicating the raw water, and producing pure water through the water production passage. According to the control method for the water purifier and the water purifier, a scale inhibitor in the scale inhibition mechanism can be effectively prevented from being kept in a dissolved state all the time and consumed too fast.

Description

[0001] This application is a divisional application with the application number "201510809043.9", the application date is "November 20, 2015", and the title of the invention is "a control method for a water purifier and a water purifier". technical field [0002] 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 [0003] 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 impa...

Problems solved by technology

[0005] However, at present, the antiscaling mechanism in the water purifier is in a state of being soaked in water for a long time, and the antiscalant in the antiscaling mechanism will dissolve 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

[0006] 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
