In other words, the water purifier has a large part of the treated residual water in the water production process. Because this residual water is still good domestic water, it is a great waste to discard it, and it is also difficult to recycle it. Repeated filtration, increase the water production rate, set up another container to fill... In short, the trouble of returning water treatment is self-evident; if it is directly discharged into the sewer, it is not a national policy to waste precious water resources

Embodiment Construction
[0049] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0050] Such as figure 1 As shown, the top and bottom of the backwater pressure tank (20) are respectively provided with a backwater pressure tank pressure reducing valve (21), a top tee (17) and a cleaning and sewage discharge device (22) at the top of the backwater pressure tank.
[0051] Such as figure 1 As shown, the top tee (17) of the return water pressure tank is connected with a universal water inlet and outlet pipe (18) extending into the bottom of the return water pressure tank (20) on its lower port.
[0052] Such as figure 1 As shown, the two sides of the tee (17) at the top of the return water pressure tank are respectively provided with a return water main pipe (25) and a return water supply pipe (8).
[0053] Such as figure 1 As shown, the front end of the return water main pipe (25) communicates with the electromagnetic reversing valve C (41) locat...

The invention belongs to the field of water purification machines, particularly a no-emission self-flush water purification machine which comprises an electromagnetic three-way four-way valve and a backwater pressure tank as core components, wherein the electromagnetic three-way four-way valve is connected into a domestic water pipeline in series and electrified to prepare water; the electromagnetic directional valve is an open circuit in the longitudinal direction, and the electromagnetic three-way four-way valve is an A-B closed circuit to form a channel A and a channel B of the electromagnetic three-way four-way valve, which are not mutually communicated; and the channel A is connected with a tapping water pipe and supplies raw water to the water purification machine. The treated water and self-flush backwater converge in the backwater pressure tank, and is communicated with the domestic water pipeline via the channel B and re-put into domestic water, thereby implementing no-emission water preparation. The self-flush function comprises a high-pressure pump A and a high-pressure pump B capable of automatically cleaning the filter element, thereby greatly enhancing the work efficiency and use period of the filter element. The no-emission self-flush water purification machine greatly enhances the work efficiency and working period of the filter element, and thoroughly utilizes the precious water resources, thereby implementing environmental protection and energy saving.
Description
technical field [0001] The invention belongs to the field of water purifiers, in particular to a water purifier with self-flushing and non-discharging functions. Background technique [0002] The water production rate of the water purifier is between 1:4----1:1. In other words, the water purifier has a large part of the treated residual water in the water production process. Because this residual water is still good domestic water, it is a great waste to discard it, and it is also difficult to recycle it. Repeated filtration, increase the water production rate, and set up another container for storage... In short, the troublesomeness of backwater treatment is self-evident; if it is directly discharged into the sewer, it is not a national policy to waste precious water. [0003] Purpose of the present invention, solve above-mentioned difficult problem exactly, open a kind of water purifier with self-washing and non-discharging function to the society. Contents of the inven...
