Description

Technical Field

[0001] The present invention relates to the field of water treatment technology, and more particularly to a purification-softening water treatment system, wherein the purification-softening water treatment system of the present invention is capable of both purifying and softening water. Furthermore, the purification-softening water treatment system can purify and soften raw water (or water to be treated) using a single control valve, such as a fluid valve, thereby enabling users to obtain both purified and softened water. Therefore, the present invention further relates to a flat valve for use in the purification-softening water treatment system. Technical Background

[0002] With people's increasing awareness of health and concerns about water pollution, water treatment machines or water treatment systems have become common household appliances. Water treatment machines, especially home water treatment machines such as central water purifiers and water softeners, are often installed in kitchens to treat water and produce cleaner water.

[0003] Water treatment machines are generally categorized as water purifiers and water softeners, depending on how they treat raw water or untreated water. Common water purifiers, such as activated carbon filtration, ultrafiltration, and RO membrane purifiers, primarily aim to remove impurities from water, such as harmful substances and foreign matter with odor. Water softeners, on the other hand, primarily remove calcium ions and other ions from water. Ultrafiltration and RO membrane purifiers treat raw water to produce relatively cleaner, more potable water. Softened water produced by water softeners, because it contains fewer calcium ions and other substances, is more suitable for bathing, washing clothes, and other activities. Some people also believe that soft water is more suitable for beauty treatments. However, existing water treatment machines or systems with combined water treatment functions primarily focus on pure water purification, such as activated carbon-ultrafiltration composite water purification systems, ultrafiltration-RO membrane composite water purification systems, and PP cotton-activated carbon composite water purification systems. Combined water purification and softening systems are rare. The main reason is that there are significant differences in the mechanisms or mechanisms of water purification and water softening. When softening water, the water softener needs to regularly add salt solution (usually NaCl solution) to the softening tank (or softening resin) and clean the softening tank to prevent the softening resin in the softening tank from losing activity. In addition, in addition to adding salt solution to the softening tank, the water softener also needs to add water to its salt (liquid) tank to prevent the salt solution in the salt solution tank from being exhausted and unable to provide salt solution to the softening tank. However, all water treatment systems involve water flow control. Due to the complexity of the structure and function of the water softener for water softening, the purification-softening composite water treatment system needs to form a complex waterway and be able to achieve reasonable control over it. In order to achieve simultaneous control of the clean water path and the softening water path, most of the existing purification-softening composite water treatment systems have more than two control valves, which ultimately leads to the entire water treatment system being bloated, bulky and having a poor user experience. Furthermore, water treatment systems, especially those for home use, are typically installed under kitchen countertops, such as beneath sinks. Existing purification-softening combined water treatment systems are bulky, occupying excessive space and creating significant inconvenience for users. This, in turn, poses significant challenges in terms of maintenance and filter replacement in the event of a water treatment system malfunction. Summary of the Invention

In particular, the purified water obtained by the purification device flows sequentially to the purification water passage and the water inlet of the softening device, thereby providing purified water to the softening device.

[0007] Another advantage of the present invention is that it provides a purification-softening water treatment system, wherein the flat valve of the purification-softening water treatment system can not only control the purification-softening water treatment system to purify and soften water, but can also further control the purification-softening water treatment system to achieve other functions, such as flushing the softening tank, replenishing salt solution into the softening tank, replenishing water (or softened water) into the salt (water) tank, etc.
