Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0021] Referring to FIG. 1 , the present invention includes a filter, a solenoid valve, a pressure switch YK, a control system 7 and a water pipeline 2 . There are two filters, both of which are membrane filters, that is, double membranes. The two filters are a first filter 10 and a second filter 4, respectively. The raw water inlet port 1 is respectively connected to the third electromagnetic valve DF3 and the fourth electromagnetic valve DF4 through the pipeline 2 . The water outlet 11 of the first filter 10 and the water outlet 3 of the second filter 4 are connected to the clean water outlet 1 through the pipe 2 . The water inlet 12 of the first filter 10 is respectively connected to the first electromagnetic valve DF1 and the third electromagnetic valve DF3 through the pipeline 2 .

[0022] The water inlet 5 of the second filter 4 is respectively conne...

Abstract

The invention discloses a household fully automatic double-membrane self-washing water purification device, which consists of a filter, a solenoid valve, a pressure switch, a control system and a water pipe. The invention is characterized in that the filer is divided into a first filter and a second filter. The raw water inlet end is connected with a third solenoid valve and a fourth solenoid valve through a pipe. The purified water outlet end is connected with the outlets of the first filter and the second filter through a pipe. The water intake of the first filter is connected with a first solenoid valve and the third solenoid valve through a pipe. The water intake of the second filter is connected with the second solenoid valve and the fourth solenoid valve through a pipe. One end of a backflushing waste water discharge port is connects with a water intake of a closet water tank. The other end of the backflushing waste water discharge port is connected with the first solenoid valve and the second solenoid valve through the pressure switch. The first, second, third, fourth solenoid valve and the pressure switch are controlled by the control system.

Description

technical field [0001] The invention relates to a water purifier, in particular to a household automatic double-membrane self-flushing water purification device. Background technique [0002] At present, the membrane filters of known household water purifiers are mostly disposable and cannot be cleaned by themselves. Or some membrane filters have a flushing method, but they are not backwashing in the true sense. In addition, the flushing method using a multi-way valve, because it is a single-membrane operation, even if the positive and negative flushing of the membrane is realized, the clean water end will also be polluted by unpurified water. Backwash water is inconvenient to recycle, resulting in waste of water resources. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art and provide a household automatic double-membrane self-rinsing water purification device with simple structure, reliable performanc...
