Description

Apparatus for blocking a leakage of water of a water purifier}

The present invention relates to a water leakage blocking device of the water purifier, and more particularly, by installing a water leakage blocking device inside the water purifier so that water can be easily and easily blocked or supplied when water provided from the outside is provided inside the water purifier. It relates to a water purifier leak shutoff device.

Currently, the cold and hot water heaters are used in general homes, including general offices, public offices, public places, etc., and anyone who is unspecified can easily and conveniently select cold and hot water for drinking.

Such a water purifier removes harmful carcinogens contained in raw water and supplies purified water. The water purifier may be classified into natural filtration, direct filtration, ion exchange, and reverse osmosis.

In particular, reverse osmosis is a method of applying purified water through a membrane (reverse osmosis filter), which is an artificial osmotic pressure by applying pressure to raw water. Only the lamp can supply clean water.

As shown in FIG. 1, the conventional reverse osmosis water purifier, as shown in FIG. 1, is provided with raw water, such as tap water supplied into the water supply pipe 3 through the faucet 1, with a pretreatment filter 5 installed on the rear side of the main body 4. Various harmful organic compounds such as chlorine components are removed while passing through), and the raw water passing through the pretreatment filter 5 is boosted to a predetermined pressure according to the operation of the pressure pump while the amount of water is controlled by a water supply valve (not shown). And flows into the membrane 6.

At this time, the raw water introduced into the membrane 6 is passed through a plurality of membrane membranes (not shown) in the membrane 6 to remove various heavy metals, carcinogens, bacteria, etc. contained in the raw water, the membrane 6 The raw water passing through is passed through the post-treatment filter 7 to remove odors such as toxic gases.

While passing through the post-treatment filter 7, odors such as toxic gases are removed, and the purified water is supplied into the water storage tank 9 through the supply pipe 8.

Here, the reservoir tank 9, the filters 5, 6, 7 and the faucet 1 are connected to each other through the branch pipe and the supply pipe (8).

When purified water is supplied into the water storage tank 9, whether the purified water supplied to the water storage tank 9 is the full water level (maximum amount of water to block the purified water supplied to the water storage tank) or the low water level (the purified water starts to be supplied to the water storage tank). Detect the minimum integer quantity).

When the amount of water supplied to the water storage tank 9 is full water level, the water supply is blocked from being supplied into the water storage tank 9, and when the amount of water supplied to the water storage tank 9 is low water level, the water is supplied into the water storage tank 9. While the purified water is supplied, a constant amount of purified water is always stored in the storage tank 9.

In addition, the purified water stored in the water storage tank 9 may be provided with the purified water to the outside according to the operation of the intake lever.

However, in such a conventional water purifier, when foreign matter enters the water storage tank 9, when a large amount of water is used at a time, or when the water storage tank 9 is cleaned, the water storage tank 9 should be separated from the main body. Nevertheless, it is inconvenient to use because it does not shut off the main power supply and the water supply is continuously supplied through the water supply hole. In addition, when the water storage tank 9 is removed without shutting off the main power supply, clean water is exposed to the outside of the water purifier. There was a problem that prevented.

This leakage can be caused by various causes.

That is, water leaks in the coupling part of the branch pipe 3 which connects the storage tank 9 and the filters 4, 5, 6, and the branch pipe 3 which connects the filters 4, 5, 6 to the faucet 1. This is usually caused by the replacement of the filter (4, 5, 6) or the branch tank (3) side of the water storage tank (9) can also be caused by external damage to the heating device.

In particular, in order to cut off the water provided through the faucet 1 for the replacement of the filters 4, 5, 6, the flexible branch pipe 3 is normally folded and used to fold the branch pipe 3. As it causes external damage, the leakage phenomenon frequently occurs.

Due to such a problem, not only the malfunction of the machine can be caused by the purified water leaking to the outside of the water storage tank 9, but there is a problem in that there is a risk of a short circuit, etc., and there is a problem of lowering the reliability of the product.

Therefore, the main object of the present invention is to detect the water level by the lower cover for collecting the leaked water separately when the leakage occurs in the water purifier and the leakage shutoff valve mounted inside the lower cover to provide the water provided through the faucet It is to be able to block arbitrarily to prevent malfunction and failure of water purifier due to leakage.

In addition, another object of the present invention is to make it easier to maintain the water purifier by allowing the water supply to be easily cut off easily through the water leakage blocking device when the water purifier is repaired or leaks occur.

In case of coincidence with the ball, install a water shutoff valve to supply water to the branch pipe. The water shutoff valve is characterized in that it is configured to block the water supplied to the branch pipe by installing a bure through the connecting member to detect the water leaked from the main body.

The valve is integrally coupled to the shutoff valve to rotate the shutoff valve through buoyancy by water that is fresh in the reservoir space of the lower cover to open and close the flow hole. It is characterized by consisting of the bure.

According to the present invention, the guide flange is formed at the outer periphery of the coupling flange of the branch housing, and the locking protrusion formed at the outer periphery of the shutoff valve is coupled to move in the guide hole so as to limit the rotation angle of the shutoff valve in the branch housing.
