Description

Water Purifier

The present invention relates to a water purifier that generates purified water by filtering raw water, and more particularly, to a water purifier that facilitates blocking of raw water when replacing or separating a filter.

A water purifier is a device that filters the inflow water (raw water) with a filter to generate purified water and then provides it to the user.

The filter provided in the water purifier filters a certain amount of water or when a certain period of time elapses, the performance deteriorates, so it is necessary to replace it with a new filter.

In order to replace or separate the filter, first cut off the raw water supplied to the filter. In this case, the water supply shutoff valve capable of blocking the raw water is at the rear of the water purifier, and when the rear of the water purifier is installed adjacent to the wall, there is a problem in that it is not easy to cut off the raw water.

In particular, since the water supply shutoff valve is invisible at the rear of the water purifier, if a water purifier user or manager forgets to shut off the raw water and replaces or separates the filter, a large amount of raw water is ejected from the part where the filter is separated by strong water pressure. There was a problem with accidents.

In order to solve this problem, the present applicant applied a spring-type raw water cut-off fitting structure to the first filter based on the raw water flow among a plurality of filters provided in the filter unit. has been applied

However, since this raw water blocking fitting structure is installed only on the first filter, if a water purifier user or manager separates a filter other than the first filter first, the filter is separated from the filter mounting part by the water pressure of the raw water and the raw water is ejected. This happened repeatedly. In particular, since the separated filter moves to a fairly long distance by the hydraulic pressure of the raw water, it takes a lot of time until the separated filter is installed again, and there is a risk of a PL accident in which a large amount of raw water is continuously ejected ( In this case, it is possible to cut off raw water by removing the first filter to which the raw water shutoff fitting structure is applied.
