The filter case 10 has a water storage space 36 formed in the upper and lower portions thereof and is made of a porous material to filter the raw water flowing through the outside, A water filter (34) for storing the water; A support end 48 which is installed to surround the lower side of the water filter 34 and supports the lower end of the water filter 34 and protrudes downward at the center of the lower surface is formed, A first filter fixing cover 38 which is inserted into the first filter fixing cover 38; A plurality of hooks 58 protruding from the outer circumferential surface at predetermined intervals and hooked to an inner wall of the filter case 10 so as to surround the water filter 34; A second filter fixing cover (52) fixed to the inside of the filter case (10); A blocking wall body 24 protruding in a cylindrical shape on the inner bottom surface of the filter case 10 and guiding the supply of raw water flowing into the filter case 10 through the raw water supply hole 18, ; The upper side of the blocking wall body 24 is opened by deforming by the water pressure when the raw water flows in and the upper side of the blocking wall body 24 is blocked when the supply of the raw water is stopped, And an opening / closing member (70) for preventing the water from being discharged to the outside through the raw water supply hole (18).
According to the present invention, the conventional water filter is periodically exchanged according to the degree of contamination. When the water filter is separated from the main body of the water purifier and exchanged, the water is introduced into the case to prevent the raw water from being discharged to the outside through the supply port Thereby preventing pollution around the filter and replacing the filter in a cleaner state.
In addition, when no purified water discharge pipe is provided and the purified water is immediately discharged through the lower side of the purified water storage space, the purified water is purified only through the lower end of the water filter closest to the raw water.
Therefore, since the purified water discharge pipe is installed inside the purified water storage space, and the purified water in the purified water storage space is discharged to the outside through the upper end of the purified water discharge pipe 68, the efficiency of the filter is improved because the entire water filter 34 is used .
Description
An opening / closing member made of a flexible material is provided on the inlet side of raw water, and is opened by the water pressure when the raw water is supplied. When the supply of raw water is stopped, And more particularly, to a leak prevention structure for a filter that prevents leakage of water when the filter is replaced by closing the inlet port side.
Generally, it is difficult to drink tap water supplied to each household or business premises because of water pollution. Accordingly, each home and each shop has a water purifier for purifying the polluted water (hereinafter referred to as "raw water") with water suitable for drinking (hereinafter referred to as "purified water").
Such a water purifier has a number of filters for filtering raw water. The filter usually has a configuration in which a filtering element is disposed in a cylindrical case and then an introduction port and an exhaust port are formed for introducing the raw water at both ends thereof and discharging the introduced raw water. Such filters pass the raw water introduced in the state of being connected in series to each other, thereby filtering the contaminated raw water into clean water.
Such a purifier filter is disclosed in Korean Patent Publication No. 10-0712266.
Such a water purifier filter uses a connector that simplifies the assembly operation since the connection structure of the water purification system is simplified by the structure of the water filter including the reverse osmosis membrane filter in which the passages of the raw water, the purified water, and the concentrated water are formed in a single port shape And a water purification device using the same.
However, the existing water filter is configured to be periodically exchanged according to the degree of contamination, and is disadvantageous in that the water is put into the case in the process of separating and exchanging water from the water purifier main body, and the raw water is discharged to the outside through the supply port.
In addition, the raw water leaking out to the outside not only pollutes the purifier body but also flows around and pollutes the surrounding environment.
SUMMARY OF THE INVENTION It is therefore an object of the present invention to solve the problems of the prior art as described above, and it is an object of the present invention to provide an air- And a water leakage preventing structure for preventing the leakage of water generated when the filter is replaced by shutting off the inlet port side by the water pressure of the raw water to be discharged.
According to an aspect of the present invention, there is provided a water leakage prevention structure for a filter, the water leakage prevention structure comprising: a body portion having a hollow cylindrical shape and extending vertically; A discharge hole formed in the center of the insertion port and vertically penetratingly formed to protrude downward from the center and discharging purified water from the inside of the body part; And a raw water supply hole through which a plurality of radial passages are formed to supply raw water to the inside of the body part. The filter case is installed inside the filter case, and has a water storage space formed vertically in the interior thereof. A water filter for filtering the raw water flowing through the outside and storing the purified water in the purified water storage space, A first filter fixed cover which is installed to surround the lower side of the water filter and supports a lower end of the water filter and has a support end protruding downward at the center of the lower surface and inserted into the discharge hole, A second filter fixed cover which is hooked to an inner wall of the filter case and has a plurality of hook portions protruding from the outer circumferential surface at regular intervals to fix the water filter inside the filter case, A barrier wall protruding in a cylindrical shape on an inner bottom surface and guiding supply of raw water flowing into the filter case through the raw water supply hole; The upper side of the blocking wall is opened, and when the supply of the raw water is stopped, the upper side of the blocking wall is blocked so that the raw water flows through the raw water supply hole And a closing member, which prevents the discharge portion.
The opening and closing member includes a fastening body having a cylindrical shape and having a fastening hole formed at a center thereof so as to penetrate the upper end and the lower end thereof to be coupled to an outer side of the fastening end, And a blocking plate formed to selectively block the upper end of the blocking wall.
The opening and closing member is made of a flexible material, and the blocking plate is elastically deformed by the water pressure to selectively open and close the upper end of the upward blocking wall.
The first and second filter fixing covers are further provided at the center thereof with first and second insertion portions inserted into the water storage space to fix the water filter.
The water purifier according to any one of
The water leakage preventing structure of the filter according to the present invention has the following effects.
According to the present invention, an opening / closing member is provided on the upper side of the raw water supply hole of the filter case, and when the raw water is supplied, the raw water is elastically deformed by water pressure to supply the raw water, Is prevented from being discharged to the outside.
Therefore, the conventional water filter is configured to be periodically exchanged according to the degree of contamination. When the water filter is separated from the main body of the purifier and replaced, the water is prevented from being discharged to the outside through the supply port. And the filter can be exchanged in a cleaner state than in the prior art.
In addition, when no purified water discharge pipe is provided and the purified water is immediately discharged through the lower side of the purified water storage space, the purified water is purified only through the lower end of the water filter closest to the raw water.
Accordingly, since the purified water discharge pipe is installed inside the purified water storage space and the purified water is discharged to the outside through the upper end of the purified water discharge pipe, the entire water filter is used, thereby improving the filter efficiency.
