Abstract

The present invention relates to the technical field of water purification equipment, in particular to a control method, a control device, water purification equipment and a storage medium of water purification equipment. The control method of the water purification equipment includes the following steps: judging whether the water purification equipment enters the standby state; when the water purification equipment enters the standby state, the pure water return branch is turned on, and the opening of the waste water valve is set to the first opening; wherein , the water purification equipment includes a reverse osmosis filter element, a waste water valve is arranged on the waste water branch road of the reverse osmosis filter element, a pure water return branch is arranged between the water outlet end and the water inlet end of the reverse osmosis filter element, and the first opening is smaller than the second The second opening is the opening of the waste water valve when the water purification equipment normally outputs pure water. The opening of the waste water valve in the technical solution of the present invention is smaller than that of the waste water valve when the pure water is normally discharged from the pure water backflow flushing state, which reduces the concentrated water discharge during backflow and saves water resources.

Description

technical field [0001] The present invention relates to the technical field of water purification equipment, in particular to a control method, a control device, water purification equipment and a storage medium of water purification equipment. Background technique [0002] At present, the reverse osmosis water purifier mainly relies on the RO membrane filter to filter the raw water. When the water purifier is in the standby state, there will be raw water and pure water in the RO membrane filter, and the TDS concentration of the raw water is much higher than that of the pure water. TDS of water, if the water purifier is in the standby state for a long time, this will cause the ions in the raw water to diffuse into the pure water, which will cause the first cup of pure water to be lost when the water purifier is turned on next time. The concentration of TDS is relatively high, which affects the user experience. [0003] In order to solve the above problems, in the prior art,...
