Description

Compound filter for water purifier {COMPOSITE FILTER FOR THE WATER PURIFIER}

The present invention relates to a composite filter for a water purifier, and more particularly, a composite filter for water purifiers, such as a sediment filter, activated carbon fiber filter, activated carbon filter, UF filter, etc. in one housing, and in particular, the sediment filter is a cylinder The present invention relates to a composite filter for the purpose of strengthening the shape to prevent water loss and to secure filtration performance.

Currently, the composite filter is composed of a sediment filter, a pre carbon filter, a post carbon filter, a UF or a RO filter to perform a unique water purification function for each stage. Each uses a separate housing and each filter is connected by a tube. In this case, the size of the product increases and it is difficult to replace the filter itself. The necessity of a composite filter for a water purifier composed of one filter housing to maintain the characteristics of the conventional composite filter and to replace the filter with a filter exchange signal has been raised. In the past, the sediment filter was laminated with a nonwoven fabric, and thus, only the foreign material was filtered. The sediment filter was easily clogged, so the entire composite filter had to be discarded. In order to solve this problem, in the past, when the pore of the sediment filter was enlarged, foreign substances were delivered to the UF membrane or the ACF material activated carbon used in the rear stage as it was blocked, resulting in premature performance deterioration. In the present invention, the sediment filter is reinforced in a cylindrical shape, and the outer pore is made to reinforce the cylindrical shape so that the pore becomes smaller toward the inside.

The present invention has been made to solve the above problems, the first object of the present invention is to provide a composite filter for a water purifier that can easily replace the filter with a filter replacement signal while reducing the size of the composite filter. .

It is a second object of the present invention to provide a composite filter for a water purifier, which extends the life of the sediment filter and prevents the blockage of the filter material at the rear of the sediment filter in advance, thereby preventing the amount of water passed through.

In order to achieve the above object, the present invention provides a sediment filter, ACF (activated carbon fiber) filter, AC (activated carbon) filter, and UF filter in one housing. It is to provide a composite filter for a water purifier composed of a cylindrical filter structure of small pores.
