Description

Compound filter for water ionizer {COMPOSITE FILTER FOR THE ION WATER MACHINE}

The present invention relates to a composite filter for water ionizer, and more specifically, to a composite filter for ionizer, such as a sediment filter, activated carbon fiber filter, activated carbon filter, UF filter in one housing, in particular the sediment filter in the form of a cylinder The present invention relates to a composite filter for ionizers aimed at preventing water loss and securing filtration performance.

Ionizer is a device that electrolyzes water into alkaline water and acidic water, and its water purification function is insufficient. Currently, in the case of an ion water filter, an activated carbon filter or a form in which an UF membrane is simply added to an activated carbon is widely used, and a necessity of a composite water filter for ion water is raised to enhance water purification performance. However, the current filter is composed of sediment filter, pre carbon filter, post carbon filter, UF or RO filter, so that each water filter has a unique water purification function. Since a separate housing is used and each filter is connected by a tube, the size of the product becomes large and the filter replacement itself is difficult.

There is a need for a composite water filter for ionizers that maintains the characteristics of a conventional composite filter while enhancing water purification. 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 transferred 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 larger to compensate for the conventional problem by reinforcing 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 the ionizer to reduce the size of the composite filter and to enhance the water purification function of the conventional ionizer. .

It is a second object of the present invention to provide a composite filter for an ionizer which prolongs 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.

The present invention for achieving the above object is to install a sediment filter, ACF filter, AC filter, UF filter in one housing, and the sediment filter of the cylindrical type that the outer pore is larger and the pore becomes smaller as it enters the inside. It is to provide a composite filter for ionizer which increases the contact area and performance by making the sediment part with the filter structure and increases the adsorption power by using ACF (fibrous activated carbon).
