Description

Water processor and shell 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 be used for sequentially carrying out purification and softening treatment on water. Further, the purification device (purification cartridge) and the softening device (softening tank) of the water treatment machine of the present invention are both provided in the housing of the water treatment machine and controlled by a single control valve.

Background

With the increasing health importance and water pollution concerns, water treatment machines 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.

Water treatment machines are generally classified into water purification machines and water softening machines 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 mostly used for removing impurities, such as harmful substances and foreign substances with peculiar smell, in water as much as possible. And the water softener is mainly used for removing calcium ion plasma in water. Purifier such as ultrafiltration purifier and RO membrane purifier handle the water phase that the raw water obtained relatively cleaner and be fit for drinking, and the water softener handles the soft water that the raw water obtained because contain less calcium ion etc. more be fit for shower, wash clothes etc.. Some people also think that soft water is more suitable for beauty. However, most of the existing water treatment machines having a composite water treatment function are water treatment machines for purifying water only, such as an activated carbon-ultrafiltration filtration composite water purification system, an ultrafiltration-RO membrane composite water purification system, a PP cotton-activated carbon composite water purification system, and the like, but there are almost few water purification-softening composite water treatment machines. The main reason is that the purification of water and the softening of water are different in mechanism or mechanism. After a user uses the water softener to soften water for a period of time, the water softener needs to periodically replenish a salt solution (typically a NaCl solution) into a softening tank (which may also be a softening tank or a softening tank) and clean the softening tank to prevent the softened resin in the softening tank from losing activity and removing impurities in the softening tank after a long period of use. In addition, the water softener needs to be replenished with water into the salt (liquid) tank in addition to the salt liquid in the softening tank to prevent the salt liquid in the salt liquid tank from being exhausted and failing to supply the salt liquid into the softening tank. However, all water treatment machines involve control of the water flow. Due to the complexity of the structure and function realization of the water softener for softening water, the purification-softening composite water treatment machine needs to form a complex water path and can realize reasonable control on the complex water path. In order to realize the control of a purified water channel and a softened water channel at the same time, most of the existing purification-softening composite water treatment machines are provided with more than two control valves, which finally leads to the overstaffed, large volume and poor use experience of the whole water treatment machine mechanism. Furthermore, water treatment machines, especially domestic water treatment machines, are typically mounted under the counter of a kitchen, such as under a hand sink. The existing purifying-softening composite water treatment machine has huge volume, occupies too much space and brings great inconvenience to the installation of users. Needless to say, maintenance and filter element replacement in the event of a malfunction of the water treatment machine.
