Description
Technical Field
The invention relates to the water treatment industry, in particular to the aspects of deep filtration and purification of drinking water.
Background
The horizontal water purifier can be placed on the table board of a kitchen cabinet or in the cabinet, and the machine is directly placed on the use position without punching and hanging, so that the horizontal water purifier is very convenient to use. Because the filter liner is positioned above the machine base, the filter liner is convenient to replace, and time and labor are saved relatively. However, the biggest problem of adopting the seat type water purifier structure is that the operation surface of the machine is small, the display window and the operation control device can only be arranged on the side vertical surface of the machine, and the top surface is used for replacing the filter container, so that parts can be placed everywhere. Since the water purifier has limited length and width dimensions, generally less than 520 mm × 200 mm × 450 mm, the installation of the display control device on the side vertical surface of the machine will affect the number of the filter cartridges. When the closed filter container is used, the water port of the filter container faces downwards, so that water in the filter container can flow out from the water port of the filter container to pollute the surrounding environment during replacement. The water in the front and back filter containers is discharged from the inlet and outlet pipes of the corresponding base until the water level in the water purifier is balanced, so that the water purifier with the base has the advantage of easy extraction of the filter containers. When the internal filter container of the open type filter cartridge is used, the internal filter container in the existing open type filter cartridge is poured out together with water after the filter cartridge is detached, and the operation is very troublesome, so that the case of cleaning the inner cavity of the filter cartridge is very rare. And because the environment for placing the water purifier is poor, the water flow speed leaking in the process of replacing the filter liner is too fast to be removed easily, thus not only causing inconvenient operation, but also causing the cabinet to be soaked and even damaging the cabinet plate. In view of the whole process that the filter container is always replaced along with the use of the water purifier, the related problems caused by replacing the filter container and cleaning the filter channel can be frequently repeated. In addition, the scaling phenomenon of the filter cartridge and the inner wall of the pipeline of the water purifier is very serious after the water purifier is used for a long time, and the water purifying treatment environment of the water purifier is increasingly poor. Especially, the problems of cleaning the inner cavity of the upper open type filter cylinder, discharging sewage containing a large amount of impurities and extracting the built-in filter liner are not solved, so that a machine model of a lower machine base is rarely adopted. Even, no water purifier capable of cleaning the filter cartridge is available so far. On the other hand, the filter liner replacement and cleaning maintenance of the water purifier require professional personnel to go to the home for service, and the professional personnel are reluctant to provide the home cleaning service due to the lack of cleaning means, labor and time, so that the problem of machine cleaning is rarely mentioned to users. So that most users only know to replace the filter cartridge, but few know to regularly clean the machine. In addition, the waste of water resource is very serious to current nanofiltration membrane and reverse osmosis membrane purifier. Typically, the "concentrate" discharged by the machine is about 3 times the "pure water" produced. The concentrated water is purified water which is filtered by a filter liner of a pre-arranged micro-filtration membrane, and is directly discharged to cause waste. The above-mentioned drawbacks and disadvantages make it difficult to widely popularize the water purifier.
