Description

Complex filter assembly and water purifier having the same The present invention relates to a composite filter assembly in which a plurality of filters are integrated and a water purifier equipped with the same, and more specifically, to a composite filter assembly having a plurality of inlets and a plurality of outlets and a water purifier equipped with the same. A water purifier is a device that filters incoming water and discharges it to supply drinking water to the user. These water purifiers had a problem in that the product system was complex and the volume occupied by the filters on the product increased, thereby increasing the overall size of the product, as they used a combination of three or more individual filters to filter the incoming water to be treated (e.g., raw water). To solve these problems, a technology has been proposed to use a combination of two filters. For example, a composite filter assembly in which a sediment filter and a pre-carbon filter are integrated as pre-treatment filters, or a composite filter assembly in which a pre-carbon filter and a hollow fiber membrane filter are integrated, has been used. However, conventional composite filter assemblies have a single inlet and a single outlet, and are configured with multiple filters arranged in series along the flow path inside. That is, conventional composite filter assemblies are configured to have a structure in which water introduced through the inlet is filtered through the first filter, the water filtered by the first filter is introduced into the second filter for further filtering, and then discharged through the outlet. These conventional composite filter assemblies had a problem in that the replacement cycles of the filters contained within them differed, so when the replacement cycle of some filters was due, the entire composite filter assembly had to be replaced, which meant that even filters with remaining service life had to be replaced. In addition, conventional composite filter assemblies had a problem in that, since multiple filters are arranged in series, other filters or components could not be installed between the filters.
