Problems solved by technology

[0003] 1. If the water purifier is not used for a long time, the particles in front of the RO (Reverse Osmosis, reverse osmosis) membrane in the filter element of the water purifier penetrate through the RO membrane to the pure water end, resulting in TDS (Total dissolved solids, total dissolved solids) in the first cup of water Solid) is high, affecting user experience;
[0004] 2. If the water purifier with built-in water tank is not used for a long time, the water quality in the water tank will deteriorate and cannot be drained automatically

Abstract

The invention relates to a water purifier and a control method and device thereof. The water purifier comprises: a water inlet connector, communicated with a water inlet of a front filter element; a water inlet pipeline, communicated with a water outlet of the front filter element and a water inlet of the reverse osmosis filter element, and a first electromagnetic valve and a booster pump being arranged on the water inlet pipeline; a wastewater pipeline, communicated with a wastewater outlet of the reverse osmosis filter element and the wastewater interface; a pure water pipeline, communicatedwith the pure water outlet and the water inlet of the pure water tank and provided with a second electromagnetic valve; a water inlet of the water pump communicating with a water outlet of the pure water tank; a return pipeline, communicated with a water outlet and a return water port of the water suction pump, the return water port being positioned on the waterway pipeline between the water inlet interface and the water inlet of the reverse osmosis filter element, and a third electromagnetic valve being arranged on the return pipeline; a water outlet pipeline, communicated with a water outlet of the water suction pump and the water outlet connector and provided with a fourth electromagnetic valve. According to the technical scheme, the situation that the TDS value of the first cup of water is high can be avoided, and pure water with poor water quality due to too long storage time in the water tank is prevented from being used by users.

Description

technical field [0001] The present disclosure relates to the technical field of water purification, in particular to a water purifier and its control method and device. Background technique [0002] With the improvement of people's living standards, people pay more and more attention to water quality and sanitation. It has become a trend to equip households with water purification equipment; The device has the following disadvantages: [0003] 1. If the water purifier is not used for a long time, the particles in front of the RO (Reverse Osmosis, reverse osmosis) membrane in the filter element of the water purifier penetrate through the RO membrane to the pure water end, resulting in TDS (Total dissolved solids, total dissolved solids) in the first cup of water Solid) is high, affecting user experience; [0004] 2. If the water purifier with built-in water tank is not used for a long time, the water quality in the water tank will deteriorate and cannot be drained automatic...
