Description

Waterway controller and waterway control device for multifunctional water treatment system

Technical Field

The invention relates to the technical field of water treatment, in particular to a waterway controller which can realize the control of the supply of raw water (or water to be treated) and the supply of water after different treatments to a water treatment system, in particular to a water treatment system.

Background

With the increasing health concerns and concerns about water pollution, water treatment machines or systems have become common household appliances. Water treatment machines, especially household water treatment machines, such as central water purifiers, water softeners and the like are often installed in kitchens to treat water and obtain cleaner water.

To obtain water that is sufficiently clean or meets certain requirements, such as more potable water and/or softened water having a lower hardness, existing water treatment systems often have more than one filter element. For example, many households may install a prefilter upstream of the ultrafiltration water purifier to filter out larger impurities, or an activated carbon filter downstream of the ultrafiltration water purifier to improve the taste of the purified water. Or, a pre-filter is arranged at the upstream of the water softener for softening the water to remove larger impurities, and a purification filter element is further arranged to purify the water before the water is softened. However, such a water treatment machine or a water treatment system having a complex water treatment function or a multi-stage water treatment function, such as an activated carbon-ultrafiltration filtration complex water purification system, an ultrafiltration-RO membrane complex water purification system, a PP cotton-activated carbon complex water purification system, etc., often has a complex water path. For example, a water treatment system capable of providing purified water of different purification degrees, having at least one raw water (or water to be treated) line (or pipe) and two purified water lines, a water treatment system having a combined purification and softening function, having at least one raw water line, one purified water line and/or one soft water line. In order to ensure the stability, the usability and the convenience for maintenance after the fault of the water treatment system while the water treatment system can smoothly realize the multifunctional water treatment, the prior multifunctional water treatment system is mostly provided with a plurality of auxiliary control valves besides a main control valve for controlling the water flow so as to respectively control different water paths. However, the auxiliary control valve of the existing water treatment system controls the raw water path and the different water outlet paths as end control. Therefore, when a user performs maintenance of the existing water treatment system, particularly, maintenance of the control valves for controlling the flow of raw water to the respective filter cartridges to control the multistage treatment of water, he or she has to close the auxiliary control valves of all the pipes one by one, which may cause the water supply through the water treatment system to be completely shut off and cause a safety hazard. Particularly in the case of a multi-purpose water treatment system in series with the water outlet line of a kitchen or the like, the user may have to face the situation where the water supply is completely shut off and fire safety issues should the water treatment system fail.
