Water purifier

Abstract

This invention provides a water purifier which can prevent a lowering in water purification efficiency and can realize easy maintenance and a simple construction. In the water purifier (1), a filter (5) is disposed upstream of a purifier (4) in the water flow direction. Accordingly, an ozone mixer in the purifier (4) is not affected by pressure loss caused by clogging of the filter (5), and a lowering in efficiency of mixing of ozone into water in the ozone mixer can be prevented. That is, a lowering in the efficiency of purification of water in the purifier (4) can be prevented. In the filter (5), when the maintenance of an inner case (77) is carried out, an outer case (76) is removed from the inner case (77) to expose the inner case (77), whereby easy access to the inner case (77) can be realized. This in turn realizes easy maintenance of the filter (5).

Description

technical field [0001] The present invention relates to a water purification device for purifying water. Background technique [0002] Conventionally, it has been desired to use water drawn from water sources such as wells or rivers, or rainwater as washing water or bathing water, or to be sprayed for plant cultivation. [0003] However, recently, the water quality of so-called well water has deteriorated significantly due to changes in the stratum itself or the penetration of pollutants into groundwater veins, and it has sometimes become difficult to directly use the drawn well water. Similarly, water in rivers often suffers from water quality deterioration. The deterioration of the water quality mentioned here means, for example, that the turbidity and chroma of the water increase, or that the water produces a peculiar smell, and the like. [0004] Such deterioration of water quality may be so-called "rust water" as described in Patent Document 1, for example. As for "r...
