Abstract

The invention provides a method and device for increasing the wastewater ratio of an electrodialysis water purifier and the water purifier, and the method comprises the following steps: when a regeneration instruction is received and a regeneration condition is met, controlling a booster water pump to be opened, and controlling a current-limiting electromagnetic valve and a pure water electromagnetic valve to be closed; when the flow meter is detected to have signal pulse, entering a regeneration process, applying reverse voltage to the electrodialysis filter element, acquiring liquid flow information in real time, and adjusting the working frequency of a booster water pump according to the liquid flow information; and when the water production electric quantity is equal to the regenerated electric quantity, stopping applying the reverse voltage to the electrodialysis filter element. In the regeneration process, the pure wastewater ratio of the water purifier is increased by controlling the working frequency of the booster water pump.

Description

technical field [0001] The invention belongs to the technical field of water purifiers, and in particular relates to a method, a device and a water purifier for increasing the wastewater ratio of an electrodialysis water purifier. Background technique [0002] After the electrodialysis water purifier produces water for a period of time, a large amount of mineral ions in the water are adsorbed inside the membrane, and it needs to be regenerated by reverse power before continuing to produce water. [0003] The pure wastewater ratio of existing electrodialysis water purification devices on the market is almost 1:1, and the pure wastewater ratio is less than 1:1 when the water inflow to the system is insufficient. Contents of the invention [0004] In order to overcome the above-mentioned technical defects, the present invention provides a method, device and water purifier for increasing the wastewater ratio of an electrodialysis water purifier, which can increase the ratio of...
