Water purifier and control method thereof

Abstract

The invention discloses a water purifier and a control method thereof. According to the invention, a mineralized stock solution adding device is added at the pure water outlet end of a functional filter element; the mineralized stock solution adding device is composed of a plurality of mineralized stock solution storage tanks and a mixing solenoid valve; one mineralized stock solution is stored ineach mineralized stock solution storage tank; a controller controls opening or closing of a plurality of input ends in the mixing electromagnetic valve according to mineralization parameters, so themineralized stock solutions are mixed and added into pure water according to requirements, and mineralized pure water is obtained; in the mineralized stock solution adding device, the mineralized stock solutions are added into the mineralized stock solution storage tanks and can be added or replaced, and in the using process of the mineralized stock solution adding device, the output quantity of each mineralized stock solution can be accurately controlled through the mixing electromagnetic valve, and the quantity of mineral substances cannot be changed along with the increase of water passingquantity of the filter element; and thus, the technical problems that the adding amount of mineral elements is uncontrollable and the amount of minerals can be reduced along with the increase of wateryield in an existing remineralization mode are solved.

Description

technical field [0001] The invention belongs to the technical field of water purification, and in particular relates to a water purifier and a control method thereof. Background technique [0002] At present, household water purifiers on the market are mainly based on reverse osmosis technology. The filtered water is pure water. While removing harmful substances, beneficial minerals are also filtered out, and the health problems of low mineralized drinking water are also increasing. highlight. [0003] In recent years, many water purification companies have begun to try to use pure water remineralization technology to solve the problem of lack of beneficial mineral elements in filtered water, but most of the water purifiers with remineralization function on the market are based on solid mineralization. Artificially synthesized mineralized balls or mineral fillers combined with activated carbon to form a mineralized filter element are placed in the pure water outlet of the w...
