Description

Water treatment machine and machine body thereof

Technical Field

The invention relates to the technical field of water treatment, in particular to a water treatment machine, wherein the water treatment machine can carry out purification treatment and softening treatment on water. Further, the water treatment machine purifying device (purifying filter element) and the softening device (softening tank) of the present invention are both provided in the water treatment machine, and are provided so that the purification and softening treatment of raw water (or water to be treated) can be achieved through a single control valve, thereby enabling a user to obtain purified water and softened water at the same time.

Background

With increasing health concerns and concerns about water pollution problems, water treatment machines or water treatment systems have become common household appliances. Water treatment machines, particularly domestic 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.

Water processors are generally classified into water purifiers and water softeners according to the treatment mode of raw water or water to be treated. Common water purifiers, such as activated carbon filtration water purifiers, ultrafiltration water purifiers, RO membrane water purifiers, and the like, are often used for removing impurities, such as harmful substances and foreign substances, from water as much as possible. The water softener is mainly used for removing calcium ion plasma in water. The water obtained by treating the raw water by the water purifiers such as the ultrafiltration water purifier, the RO membrane water purifier and the like is cleaner and is suitable for drinking, and the soft water obtained by treating the raw water by the water softener is more suitable for bathing, clothes washing and the like because the soft water contains less calcium ions and the like. Soft water is also believed to be more cosmetically acceptable. However, most existing water treatment machines with composite water treatment functions are water treatment machines which simply carry out water purification treatment, such as an active carbon-ultrafiltration filtration composite water purification system, an ultrafiltration-RO membrane composite water purification system, a PP cotton-active carbon composite water purification system and the like, but few water purification-softening composite water treatment machines exist. The main reason is that the purification of water and the softening of water differ greatly in mechanism or mechanism. When the water inflow is purified, a user needs to replace the filter element periodically so as to prevent the purifying filter element from losing the purifying function after long-time use. For example, although flushing and the like can extend the life of the filter cartridge, the activated carbon filter cartridge and the ultrafiltration filter cartridge need to be replaced after a long period of use. After water is softened by the water softener for a period of time, the water softener needs to periodically supplement salt solution (generally NaCl solution) into the softening tank (possibly a softening filter element or a softening tank) and clean the softening tank so as to avoid the deactivation of the softening resin in the softening tank and the removal of impurities in the softening tank after long-term use. In addition, in addition to replenishing the brine into the softener tank, the softener needs to replenish water into its brine tank to prevent the brine in the brine tank from being consumed and the brine from being supplied into the softener tank. However, all water treatment machines involve control of the water flow. Due to the complexity of the structure and function implementation of the water softener that softens water, the purification-softening complex water treatment machine needs to form a complex waterway and can be reasonably controlled. In order to realize the control of the water purifying passage and the softening water passage at the same time, most of the existing purifying-softening composite water treatment machines are provided with more than two control valves, which finally results in the whole water treatment machine with a bulky structure, a large volume and poor use experience. Furthermore, water treatment machines, particularly domestic water treatment machines, are typically mounted under kitchen countertops, such as under a sink. The prior purifying-softening compound water treatment machine has huge volume, occupies excessive space and brings great inconvenience to the installation of users. Not to mention maintenance and cartridge replacement when the water treatment machine fails. Also, the existing purifying-softening complex water treatment machine rarely provides purified water to a user at the same time when softening water. Even more, some combined clean-and-soften water processors provide only softened water, and not purified water. The user has to obtain purified water by an additional water purifying mechanism. Finally, for safety reasons, it is necessary for water treatment apparatuses, in particular water treatment machines with complex water treatment functions, to continuously supply water (or raw water) in a non-water treatment operating state. However, most of the existing purifying-softening complex water treatment machines can only supply purified water or/and softened water at the purifying or/and softening function position, and cannot continuously supply water in other working states, such as the cleaning working state of the purifying filter element of the purifying device.

It will be appreciated that the first, second, third, fourth, fifth, sixth, seventh, eighth, ninth, tenth, eleventh, twelfth, and thirteenth channels 101, 102, 103, 104, 105, 106, 107, 108, 109, 1010, 1011, 1012, 1013 of the planar valve 10 may have any extended path (or direction) capable of achieving the interconnection relationship herein; the first, second, third, fourth, fifth, sixth, seventh, eighth, and twelfth passages 101, 102, 103, 104, 105, 106, 107, 108, 1012 of the planar valve 10 are formed in the passage opening of the first fluid control surface 120 of the fixed valve plate 12, respectively, and the ninth, tenth, eleventh, and thirteenth passages 109, 1010, 1011, and 1013 are formed in the passage opening of the second fluid control surface 130 of the movable valve plate 13, respectively, and may have any shape capable of achieving the interconnection relationship herein. For example, the passage opening of the eighth passage 108 formed in the first fluid control surface 120 of the fixed valve plate 12 may be provided to have a regular shape or may be provided to have an irregular shape. Accordingly, the shape of the extension paths (or directions) of the first, second, third, fourth, fifth, sixth, seventh, eighth, ninth, tenth, eleventh, twelfth, and thirteenth channels 101, 102, 103, 104, 105, 106, 107, 108, 109, 1010, 1011, 1012, 1013 of the planar valve 10 and the channel openings thereof should not be construed as limiting the present invention.
