Description

Filter assembly {FILTER ASSEMBLY}

The present invention relates to a filter assembly, and more particularly to a filter assembly for purifying water.

Recently, with the development of the coffee market, more and more consumers are using ion exchange resin filters that adjust hardness substances such as calcium and magnesium ions in purified water.

However, conventional ion exchange resin filters have a problem in that fine particles included in raw water pass through and are not removed from purified water. To solve this problem, a filter assembly including two or more filters has been developed.

Republic of Korea Patent Registration No. 10-1762422 (2017.08.04. Publication date) (hereinafter referred to as 'prior art') discloses a 'filter for a water purifier capable of using selective materials' including two water purification filters.

In the prior art, two types of purified water can be obtained by passing either one of the two water filters or both of the two water filters, and the user can obtain two purified water. It was developed so that you can drink it by choosing from ports.

However, the prior art has a problem in that the degree of purification of water can be adjusted only in two ways. In particular, the prior art cannot control the removal of mineral components beneficial to the human body and water hardness, and also has a problem in that the mineral components are excessively removed.

Also, in the case of a filter assembly including two filters, it is common that the first filter removes hardness components from raw water and the second filter removes chlorine.

However, fine particulate contaminants contained in raw water may pass through the first filter as it is, and the second filter may remove heavy metals such as lead, cadmium, and mercury, and special contaminants such as chloramine and volatile contaminants. There was also a problem that the material could not be removed.
