Description

Water Purifier {WATER PURIFIER WITH READILY REPLACEABLE FILTER}

The present invention relates to a water purifier, and more particularly, to a water purifier that is easy to replace the filter and can effectively block the introduced raw water.

In recent years, water pollution has gradually increased, and it is difficult to drink tap water supplied to each home or business. Accordingly, each household or business may purify contaminated water (hereinafter, referred to as 'source water') to water suitable for drinking (hereinafter, referred to as 'clean water'). It is a common trend to have a water purifier.

These water purifiers are equipped with a plurality of filters for filtering various kinds of foreign substances by filtering raw water, and these filters are connected in series with each other so that raw water can pass in turn. On the other hand, the filter usually needs to be replaced after a certain period of time depending on the degree of water contamination or the flow rate of the filtered water. Contaminated filters not only significantly reduce their purification capacity, but can even provide a habitat for bacteria, which can increase water contamination.

Various types of filters are used depending on the type of water purifier or the water purification method, and specific examples include precipitation filters, carbon filters, hollow fiber membrane filters, and reverse osmosis filters. Among them, reverse osmosis filter has the ability to filter most foreign substances larger than water molecules, and is divided into high pressure type and low pressure type according to the size of the filtration area.

On the other hand, the conventional water purifier has a problem that it is difficult to replace the filter as described above. That is, the conventional filters are connected to each other by separate connectors screwed to the inlet and the outlet of the filter. In order to replace the filters having different exchange periods, both ends of the screwed connector are connected from the inlet and the outlet of the filter. After loosening the filter, it was necessary to screw both ends of the connector to the filter inlet and outlet again after replacing it with a new filter. In particular, when replacing the filter, there was even the inconvenience of replacing the filter in a state in which the pressurized raw water supplied from the tap or feed water pump must be shut off. On the other hand, due to such drawbacks, each household has selected a water purifier management company to request a replacement of the filter, which increases the cost of maintenance and management of the water purifier.

Accordingly, the present invention has been made to solve the conventional problems as described above, the object is to provide a water purifier configured to facilitate the replacement of the filter.

Another object of the present invention is to provide a water purifier configured to effectively block the raw water introduced into the water purifier when the filter is replaced.
