Abstract

The invention discloses a water purifier pressure regulating pump control method and a water purifier. The method comprises the following steps: acquiring the TDS value and the temperature value of raw water at the upstream of a pressure regulating pump and the original voltage value of the pressure regulating pump after a water purifier starts to produce water; making the water purifier acquire the actual pure water quantity currently generated by the water purifier, and when the actual pure water quantity reaches a preset pure water quantity, making the water purifier calculate a theoreticalvoltage value needing to be adjusted by the pressure regulating pump according to the TDS value of the raw water, the temperature value of the raw water, the original voltage value of the pressure regulating pump and the actual pure water amount generated by the water purifier, and adjusts the original voltage value of the pressure regulating pump to be the theoretical voltage value, so that theraw water subjected to water pressure adjustment by the pressure regulating pump has a proper water pressure value. According to the invention, the self-voltage value is self-adaptively adjusted through the pressure regulating pump according to parameters such as water quality conditions, water temperature and the like of different regions, so that the noise of the water purifier is reduced, and the service life of the reverse osmosis membrane unit in the water purifier is prolonged.

Description

technical field [0001] The invention belongs to the field of water purifiers, and in particular relates to a control method of a pressure regulating pump of a water purifier and a water purifier. Background technique [0002] Most reverse osmosis membrane water purifiers use a DC pressure regulating pump to increase the water pressure in front of the reverse osmosis membrane, so that water can pass through the reverse osmosis membrane smoothly, thereby performing water quality filtration. However, due to the different water quality in different regions, in the case of using a constant pump voltage, the region with better water quality will cause excessive pressure in front of the reverse osmosis membrane, causing noise and reducing the service life of the reverse osmosis membrane. Raw water with low temperature and high pressure will lead to risks such as bursting of water pipes and reduced life of reverse osmosis membranes. [0003] In view of this, the present invention i...
