Abstract

The invention relates to a water purifier. The water purifier comprises a reverse osmosis membrane filter element, a water storage tank and a switch valve, wherein the reverse osmosis membrane filterelement comprises a water inlet, a pure water outlet and a concentrated water outlet; the water storage tank comprises a pure water chamber; the pure water outlet of the reverse osmosis membrane filter element is connected to the pure water chamber, and the pure water chamber is connected to a water port by a pure water outflow pipeline; and the switch valve is connected to the water inlet of thereverse osmosis membrane filter element by a water inlet pipeline. The water purifier further comprises a pressure sensor and a controller, wherein the pressure sensor is configured to detect pressurein an internal pipeline of the water purifier, and the controller is configured to receive values measured by the pressure sensor and determine running state of the water purifier according to the pressure in the internal pipeline. The invention further relates to a running state monitoring method of the water purifier. The water purifier and the running state monitoring method thereof can guarantee the effective operation of the water purifier by means of a simple structure, and can determine the running state in real time, thereby not only saving cost, but also improving user experience.

Description

Technical field [0001] The invention relates to a water purifier and a method for monitoring the running state of the water purifier. Background technique [0002] The content in this section only provides background information related to the present invention, which may not constitute prior art. [0003] Water is an indispensable resource in life. With the improvement of the quality of life, people pay more and more attention to water safety and put forward higher requirements on water quality. In order to eliminate the pollution of water sources and transportation processes and the impact on water quality, water purifiers are increasingly used. One of the widely used water purifiers is the reverse osmosis water purifier. The reverse osmosis water purifier includes a reverse osmosis membrane filter element and a water storage tank. In order for the reverse osmosis membrane filter element to work normally, a certain pressure difference needs to be generated between the inlet o...
