Abstract

The invention relates to the field of household water purifiers, and particularly discloses a household water purification device and a control method thereof. The household water purification device comprises a plurality of desalting filter element sets, each desalting filter element set comprises at least one electrically-driven desalting filter element, and the electrically-driven desalting filter elements conduct desalting treatment on flowing water when being powered on in the forward direction, and release adsorbed salt substances into the flowing water when being reversely electrified; according to the method, part of the electrically-driven desalting filter elements are reversely electrified to release the salt substances, meanwhile, the power supply current of the power supply assembly is detected, and reverse electrification of the electrically-driven desalting filter elements to be regenerated is increased when the power supply current is reduced to a small value, so that the power supply assembly can be prevented from being overloaded, overcurrent is prevented, and the electricity utilization safety and the regeneration efficiency of the electrically-driven desalting filter element are ensured.

Description

technical field [0001] The present application relates to the technical field of household water purifiers, in particular to a household water purifier and a control method thereof. Background technique [0002] Tap water is usually treated by chlorination, which can effectively prevent water-borne diseases. However, tap water contains salt, impurities, and residual chlorine, etc., and is not suitable for drinking, washing dishes, and washing clothes. It needs to be purified before use. [0003] In the prior art, reverse osmosis membranes are often used to purify tap water to produce pure water with relatively soft hardness. The reverse osmosis membrane can effectively prevent bacteria, viruses, scale, salt ions and other substances, and only allow water molecules to pass through, thus ensuring the safety of water. During the treatment process, bacteria, viruses, scale, salt ions and other substances that do not pass through the reverse osmosis membrane will form concentrat...
