Reverse osmosis water purification machine system and control method thereof

Abstract

The invention relates to a reverse osmosis water purification machine system and a control method thereof. The system comprises a reverse osmosis film filter element, a water inlet channel, a pure water channel, a wastewater channel, a primary filter device, a booster pump and a control circuit. The reverse osmosis film filter element is provided with a water inlet, a pure water opening and a wastewater opening. The water inlet channel is communicated with the water inlet. The primary filter device is arranged on the water inlet channel. The pure water channel and the wastewater channel are communicated with the pure water opening and the wastewater opening respectively. The booster pump is arranged on the water inlet channel or the pure water channel and electrically connected with the control circuit. The primary filter device comprises at least one primary filter element, wherein the water inlet end or water outlet end of the primary filter element is provided with a pressure sensor, and the pressure sensor is arranged on the water inlet channel and electrically connected with the control circuit. The control circuit of the reverse osmosis water purification machine system can carry out analysis according to data detected by the pressure sensor and control the system to work in the optimal mode or send out some warnings, and therefore a user can carry out the next operation.

Description

technical field [0001] The invention relates to a flow regulating device, in particular to a reverse osmosis water purifier system mainly used in water treatment equipment and a control method thereof. Background technique [0002] With the continuous improvement of the quality of life, some water treatment equipment (such as water purifiers, instant electric kettles, etc.) need to accurately adjust the flow of water, but the current water treatment equipment is generally adjusted by controlling the input power of the water pump. The water flow, the adjustment of the water flow is not accurate enough, and, due to the long-term change of the power of the water pump during use, it is easy to cause damage to the water pump. [0003] In addition, since the water circuit of water treatment equipment generally includes electrical components such as solenoid valves, flow meters, and water flow sensing devices, these electrical components are connected separately in the water circui...

AI Technical Summary

Problems solved by technology

If the water quality in some usage occasions is very good, too much waste water output will be wasteful; if the water quality in some usage occasions is too poor, the wastewater output volume is too small, and the sewage discharge capacity of the filter membrane in the water filtration device is insufficient, which may cause the filter membrane to be damaged in advance
