Description

TECHNICAL FIELD [0001] The present invention relates to a purifier having an electrolytic module,

More particularly, the present invention relates to a water purifier provided with a small-capacity electrolytic cell module that is easy to expand, and more particularly, to a water purifier having a capacity of an electrolytic cell assembled in a modular form according to the required water capacity, Also, the present invention relates to a water purifier capable of improving filtration efficiency by minimizing drainage by re-filtering wastewater filtered and disposed in a filter.

Generally, a water purifier is configured to receive raw water (for example, tap water) from the outside and filter it through a filter or the like and then drink it. Recently, a water purifier that provides various functions with various functions according to the demand of the consumer has appeared.

Patent document 1 discloses such a water purifier. The water purifier includes a filtration section for filtering the incoming water, a storage section including a first tank connected to the filtration section to store the filtered water in the filtration section and a second tank connected to the first tank, And a sterilizing unit connected to the tank for circulating and sterilizing the water in the second tank, so that circulation and sterilization are possible.

However, the existing water purifier had the following problems.

(1) When the purifier capacity increases according to the processing capacity of the purifier, the size of the hydrogen generator (electrolyzer) must be increased to handle the purifier capacity. Therefore, it is troublesome to re-manufacture the electrolytic cell according to the capacity of the water purifier required.

(2) Because of this inconvenience, the increase in the number of processings due to the production of the water purifier, etc., not only lowers the manufacturing efficiency but also increases the manufacturing cost.

(3) On the other hand, in the case of a water purifier equipped with such an electrolytic cell, a reverse osmosis filter is used as one method for improving the filtration performance. However, in the case of the reverse osmosis filter, a large amount of discharged water is discharged to the outside after filtering.

(4) As the amount of water discharged from the filter increases, the more raw water is required to obtain the desired water number.

(5) In addition, since a large amount of drainage is required, a separate drainage facility must be provided for this, so that the construction is complicated. In addition, there is a need to frequently drain the drainage tank when there is no drainage facility.
