Description

  The present invention relates to a water purifier.

  Conventionally, tap water has been obligated to add chlorine for sterilization, and there is little concern that tap water will be contaminated by various germs, but the taste of water has been impaired due to the odor of chalk. It has also been confirmed that carcinogenic trihalomethanes are produced in tap water by reacting chlorine with organic substances such as humic substances contained in tap water. Furthermore, due to recent pollution of rivers and lakes, etc., it has been confirmed that tap water that uses these as raw water contains mold odor-causing substances as trace components. Therefore, water purifiers are widely used to remove substances that impair the taste of water and harmful substances.

  The general structure of a water purifier includes a cartridge 101 having a granular filter medium layer 100 filled with a granular filter medium such as activated carbon, as shown in the schematic cross-sectional view of FIG. An original water inlet 102 is formed on the bottom surface of the cartridge 101, and tap water is introduced into the cartridge 101 through the original water inlet. Further, a water discharge pipe 103 communicating with the inside of the cartridge 101 is connected to the upper part of the cartridge 101 so that tap water purified by being guided to the cartridge can be discharged to the outside.

  According to the water purifier configured as described above, it is possible to purify the tap water by adsorbing the harmful substances contained in the tap water introduced from the bottom of the cartridge 101 to the surface of the particulate filter medium.

  However, if the use of the water purifier as described above is continued, the tap water guided to the water purifier is distributed in a specific route in the granular filter medium layer, and the entire granular filter medium layer is evenly distributed. The problem that it becomes difficult to come into contact with tap water occurs. Thus, in a granular filter medium layer, when the area | region which contacts with tap water well and the area | region which does not contact tap water generate | occur | produce very much, a granular filter medium layer will deteriorate locally. When the local granular filter media layer deteriorates, the harmful substance removal efficiency of the water purifier will be greatly deteriorated, and it will be difficult to efficiently remove harmful substances contained in tap water. The problem occurs.

  Moreover, as a result of local deterioration of the granular filter medium layer, the particulate filter medium as a whole has a reduced efficiency of removing harmful substances even though there is still a granular filter medium having a harmful substance removal capability. Therefore, it is necessary to replace the cartridge having the granular filter medium layer, and there is a problem that it is not economical.

  This invention is made | formed in order to solve such a problem, Comprising: It aims at providing the water purifier which can purify to-be-processed water, such as a tap water, efficiently.
