UF WATER PURIFYING UNIT AND WATER PURIFIER HAVING THEREOF

摘要

PURPOSE: An ultrafiltration(UF) unit and a water purifier equipped with the same are provided to prevent the discoloring of purified water and to control the linear velocity of water through filters by using a pipe width adjusting pin. CONSTITUTION: An UF unit includes a filtering part and a flow controller(30). The inner cross section of the flow controller is adjusted. The linear velocity of water through the filtering part satisfies the range between 10cm/min and 17cm/min. The filtering part includes a settling filter, a pre-carbon filter, a post-carbon filter, and an UF filter. The flow controller is installed at the inlet of the pre-carbon filter or the outlet of the UF filter. The flow controller includes a pipe width adjusting pin.
