Example Embodiment

[0045] figure 1 It is a schematic principle diagram of a water purification device according to an embodiment of the present invention. See figure 1 The water purification device may generally include a filter module 103 and a water softener module 107. Wherein, the filtering module 103 is configured to receive and filter external incoming water to form filtered water. The water softening module 107 is configured to deionize the filtered water from the filtering module 103 to form softened product water. In particular, the soft water module 107 is also configured to deliver the concentrated water produced during its regeneration process to the filter module 103 to perform backwashing on the filter module 103.

[0046] The water purification device of the embodiment of the present invention uses the filter module 103 and the water softening module 107 in combination to organically combine the two to achieve complementary functions. The filter module 103 filters macromolecular sub...

Abstract

The invention provides a water purifying device and a control method thereof.The water purifying device comprises a filter module arranged to receive and filter external inflow water to form filtered water, and a water softening module arranged to deionize the filtered water from the filter module to form softened water.Moreover, the water softening module is further arranged to convey concentrated drained water generated in the regenerating process of the water softening module to the filter module to back flush the filter module.The invention further provides the control method of the water purifying device.Due to the fact that the concentrated drained water generated in the regenerating process of the water softening module is utilized for back flushing the filter module, the filter module can be cleaned conveniently, the service life of the filter module can be prolonged, the water yield of the water purifying device is remarkably increased, and full utilization of water resources is achieved.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a water purification device and a control method thereof. Background technique [0002] With the development of the economy, the shortage of water resources and pollution have become more and more serious, and the safety of drinking water for urban residents has become prominent. In response to the pollution of urban tap water, more and more water purification equipment has begun to be used in households. Reverse osmosis (RO) membranes are more common water purifier equipment. Reverse osmosis, also known as reverse osmosis, is a membrane separation operation that uses pressure difference as the driving force to separate the solvent from the solution. Because it is opposite to the direction of natural infiltration, it is called reverse osmosis. According to the different osmotic pressures of various materials, the reverse osmosis pressure greater than the osmotic pressur...
