As the above-mentioned compressed body 55, any one of a pulp compressed body, a sponge paper (also referred to as a "paper sponge"), a nonwoven fabric, and rayon that expands by about 10 times when absorbing water is used.

The above-mentioned compression body 55 is exposed from the bottom surface of the lower case 56 is formed with a protrusion (55a) on the bottom to minimize the time that the leaked water is contacted and absorbed.

When the stopper 64 described above presses the check valve plunger 57 by the stopper 64 to open the raw water movement passage 53, the coupling hole 67 formed in the bottom surface of the upper case 54.

The upper case 54 is detachably fixed to the bottom plate 62 (in case of metal) of the structure in which the water purifier 51 is installed (for example, an sink for undersink). A magnetic body 59 fixed to the bottom surface of the extension piece 54a of 54).

Extension piece of the upper case 54 to detachably fix the upper case 54 to the bottom plate 62 of the structure in which the water purifier 51 is installed (for example, the sink for the undersink). And a double-sided tape 60 fixed to the bottom surface at 54a.

Extension piece of the upper case 54 to detachably fix the upper case 54 to the bottom plate 62 of the structure in which the water purifier 51 is installed (for example, the sink for the undersink). 54a, a screw 61 fixed to the bottom surface.

At least one of the upper case 54 and the lower case 56 described above is formed of a transparent body (eg, ABS material, PC material, etc.).

In the figure, reference numeral 61a denotes a screw for fastening the upper case 54 and the lower case 56.

Hereinafter, with reference to the accompanying drawings an example of the use of the water purifier leak prevention apparatus according to an embodiment of the present invention will be described in detail.

A) Raw water is supplied from the raw water supply source to the water purifier 51 through the raw water leakage preventing device A with reference to the accompanying drawings.

As shown in FIGS. 3, 4, 5, 8, and 10, when the undersink water purifier 51 is installed in a kitchen sink such as an apartment, a house, or an officetel, a part of the raw water from the raw water supply source may be a faucet ( 70 is directly supplied and used, and a part of the raw water from the raw water supply source is supplied to the water purifier 51 through the leakage preventing device A.

The raw water supplied to the water purifier 51 is purified by passing through a stepwise water filter (for example, four water filters are used) connected in series and sequentially (moved in the direction of the arrow shown in FIG. 10 in the drawing). Then, it is supplied to the facet 71 and used.

At this time, since the first catching jaw 65 of the stopper 64 is supported by the engaging hole 67 of the upper case, the check valve plunger 57 is illustrated by the stopper 64 in FIGS. 3 and 8. It is pressed upward and to the left direction (at this time, the elastic member 63 receives a compressive force).

The initial state in which the raw water moving passage 53 is opened can be maintained. Accordingly, the raw water from the raw water supply source flows into the raw water movement passage 53 of the upper case 54 through the raw water inlet 50 and then moves to the water purifier 51 side through the raw water discharge port 52. The raw water flowing through the raw water inlet 50 passes between the " + " ribs 57b of the check valve plunger 63 and is moved toward the raw water outlet 52.

The O-ring 64a mounted on the outer surface of the stopper 64 described above maintains the airtightness of the gap between the upper case 54 and the stopper 64. As a result, the raw water introduced into the raw water moving passage 53 is prevented from leaking toward the compressed body 55 introduced into the lower case 56 through the coupling hole 67 of the upper case 54.

In addition, since the raw water or the purified water does not leak from the water purifier 51, the raw water is not supplied to the compressed body 55 through the through grooves 56a formed on the bottom surface of the lower case 56. As a result, the compressed body 55 does not absorb water and maintains a dry initial state.

B) Blocking the raw water supplied to the water purifier 51 from the raw water supply source will be described according to the accompanying drawings.

As shown in Figs. 2, 9 and 10, a part of the raw water from the raw water supply source is directly supplied to the faucet 70, and a part of the raw water from the raw water supply source passes through the leakage preventing device A to purify the undersink. Supplied to 51.

When water leaks from the water purifier 51, the leakage water accumulates on the bottom plate 62 of the sink. At this time, the compression body 55 is expanded due to absorption of leakage water flowing into the lower case 56 through the through grooves 56a formed on the bottom surface of the lower case 56 fixed to the bottom plate 62.

At this time, the support plate 58 fixed to the compressed body 55 is raised in the lower case 56 along the expanded compressed body 55. As the second catching jaw 66 of the stopper 64 is elastically deformed by pressing upward in the drawing of FIG. 9 due to the rising of the support plate 58, the first catching jaw 65 of the stopper 64 is elastically deformed. Is separated from the coupling hole (67). At this time, since the second catching jaw 66 is supported by the coupling hole 67, separation of the stopper 64 from the upper case 54 is prevented.

The check valve plunger 57 is pressurized in the right direction in the drawing of FIG. 9 by the elastic restoring force of the elastic member 63 and the hydraulic pressure applied to the check valve plunger 57, thereby advancing the raw water movement passage 53. Close it. At this time, the stopper 64 is moved to the right in the drawing by the check valve plunger 57 inside the upper case 54.

That is, the raw water movement path 53 is closed by the airtightness of the O-ring 57a attached to the outer surface of the check valve plunger 57. Accordingly, the raw water flows into the upper case 54 through the raw water inlet 50 from the raw water supply source and blocks the raw water flow that is moved toward the raw water outlet 52.

Therefore, since the inflow of raw water to the water purifier 51 is prevented, further leakage of fluid (say, raw water or purified water) from the water purifier 51 is prevented.

As described above, since the raw water supplied to the water purifier 51 is automatically cut off when water leakage occurs from the water purifier 51, the user can confirm that the water is leaked from the water purifier 51 and take a predetermined action.

On the other hand, since the upper case 54 is detachably fixed to the bottom plate 62 of the sink by the screw 61, the magnetic body 59, the double-sided tape 60 or the like, water is absorbed from the lower case 56. The compressed compact 55 can be replaced with a new compact. This makes it possible to reuse the water purifier leak prevention device repeatedly.

As shown in Figure 11, the water purifier leak prevention apparatus according to an embodiment of the present invention, after the raw water supplied from the raw water supply source purified water by using a water filter (for example, four water filters are used), the user It can be provided in the upstream pipe of the water purifier 51 provided so that Ga can drink purified water.

At this time, when the raw water or purified water leaks from the water purifier 51, the raw water movement passage by the check valve plunger 57 is interlocked as the compression body 55 is expanded when absorbing the leakage water flowing into the lower case 56. The technical content of closing the 53 and blocking the movement of the raw water to the water purifier 51 side is applied substantially the same as that shown in Fig. 7, so that detailed description thereof will be omitted.

As described above, the water purifier leak prevention device according to an embodiment of the present invention, when the volume of the pulp compressed body absorbing the leaked water leaked from the water purifier, etc. is expanded, flows into the water purifier, etc. by the check valve plunger interlocked. Automatically shut off the raw water to prevent further fluid leakage. After using the leak prevention device once, it can be used repeatedly by replacing only the pulp compacted material. There is no fear of malfunction or malfunction of the leak prevention device, so it can provide the user with reliability and safety.
