Description

Leak prevention device of water purifier

The present invention relates to an apparatus for preventing water leakage of a water purifier, and more particularly, the water tank is installed at a connection portion of a raw water supply pipe connected to the outside of a water purifier and a reservoir, and has a structure that operates according to the level of fresh water stored in the reservoir. When a certain amount of fresh water is loaded in the buoyancy member of the leakage preventing device is lifted and at the same time the inflow of raw water supplied from the outside is related to a water leakage preventing device of the water purifier that can prevent the leak inside the water purifier.

Generally, water purifier removes heavy metals and other harmful substances contained in raw water through the process of sedimentation, filtration and sterilization of raw water such as tap water, and can be used as drinking water. According to the name of the serious level, tap water is not directly used as drinking water at home or at work.

Such water purifiers are widely used not only for general households and businesses, but also for cutting-edge scientific industries or cleaning or medical use of high-precision electronic components.

The structure of the water purifier includes an outer case, a plurality of filters installed inside the outer case to filter and purify time water flowing into a cold water purifier, a cooler for keeping the time water purified by the filter cool, and the cooler. A cold water tank for temporarily storing the chilled water, and a heater for keeping the purified water warmed, a hot water tank for temporarily storing the water heated by the heater, and a spout port of the cold water tank and the hot water tank, respectively. It protrudes outside of the outer case and consists of a cold water intake cock for taking out cold water and hot water, and a hot water intake cock.

In the water purifier, when water is introduced from the outside, the water introduced by the filter unit is filtered to remove impurities and bacteria contained in the water, and then supplied and stored through a hose to a cold water tank and a hot water tank.

At this time, the water stored in the cold water tank is made cold by the cooler installed on the outside of the cold water tank, while the water stored in the hot water tank is heated to a predetermined temperature by a heater installed on the outside of the hot water tank.

Since the water pressure of the raw water is always applied directly to the water purifier, there are various components such as various filters and hot water tanks inside the water purifier, and each of them is connected in series or in parallel so that many joints are formed. If gaps or cracks occur in any joint or weak strength part of the water purifier, water flows through the gap or cracks and collects in the water purifier body, and after a certain time, the accumulated water flows out of the water purifier. It also made water around the water purifier.

Accordingly, methods for preventing water leaks in water purifiers have been proposed and widely used. As one method, a user directly cuts off a main valve through which water is introduced from the outside, and another method is a mechanical type inside the water purifier. Equipped with a leak shutoff device or installing a sensor to detect water in the water purifier main body and make the main valve as a solenoid valve, when the signal is detected by the sensor to operate the solenoid valve to block the inflow of water from the outside have.

However, as described above, in the case of the manual on-off valve in which the user directly cuts off the main valve, the user must directly check whether there is a leak. Therefore, if the leak is not checked, the leak cannot be prevented. There was a problem that the use is cumbersome by directly opening and closing the valve whenever necessary, such as when going out.

In addition, the method of using a mechanical leak blocking device has a problem that a malfunction or breakdown occurs according to a long time of use and thus a leak cannot be completely prevented.

In addition, the method of blocking the leak using the detection sensor and the solenoid valve has a problem that it is difficult to prevent the leak occurring in the pipe before the point where the solenoid valve is installed as the solenoid valve is mounted on the connecting pipe connecting the plurality of water filters. The solenoid valve is not a device for blocking a leak, but a water filter for the water filter, and has a problem that it is difficult to completely block the leak when a leak occurs through the piping and connecting parts inside the water purifier.

The present invention has been invented to solve the above problems, the leakage preventing device is installed in the connection portion of the raw water supply pipe and the reservoir connected from the outside of the connection pipe for connecting a plurality of water filters, the fresh water stored in the reservoir By having a structure that operates according to the water level, when a certain amount of fresh water is loaded into the reservoir tank, the buoyancy member of the leak prevention device is lifted and at the same time, the inflow of raw water supplied from the outside can be prevented in advance to prevent leakage of the water purifier. It is an object of the present invention to provide a water leakage preventing device for a water purifier.

Still another object of the present invention is to prevent secondary damage caused by water leakage (water distorted wood floor and fire caused by water leakage), thereby preventing water damage from water damage. The object is to provide a prevention device.

In order to achieve the above object, the present invention provides a buoyancy member and a buoyancy member attached to one side of the buoyancy member in constructing a water purifier leak prevention device installed at a connection portion of a water supply pipe and a water reservoir connected from the outside of the water purifier. A pressurizing protrusion is formed at the end and a flow arm having a fastening member attached to one side thereof, a tubular casing having a fastening member inserting hole for inserting the fastening member on the lower surface and a flow arm inserting hole, and a plate shape inserted into the lower surface of the casing.
