Description

Detailed Description of the Invention (Prior Art) In a conventional water purifier, as shown in FIG. 2, a water purification container (cartridge) A is internally provided with a gap C provided in an outer cylinder B, and a water inlet of the outer cylinder B is used. Water is passed through the gap C, and the water that has been passed through is passed through the bottom of the water purification container A into the water purification container A. The water purified in the water purification container A by activated carbon is discharged from the drain port D, and the purified water Is available for drinking.

However, in the water purifier shown in FIG. 2, if the water supply operation is stopped and left for a long time, bacteria grow in the gap C between the water purification container A and the outer cylinder B, resulting in unsanitary water. Therefore, if you stop the water supply work and then perform the water supply work, you must pour the water from the tap into the water purifier, discard the water at the beginning of the flow, and use the water afterwards.
Since the amount of the grown bacteria is unknown, it is uneconomical to drain a large amount of water because it is unknown how much water should be drained.

Further, as shown in FIG. 3, there is a water purifier in which a water purifier A is provided with a cut membrane E for cutting bacteria, and the water purifier A is installed in an outer cylinder B. In this water purifier, the cut membrane E is not used. There are drawbacks such as clogging, the flow rate of water is reduced, the purification action is diminished, and the water purification container must be replaced in a short period of time, which is uneconomical.

(Problems to be solved by the invention) The present invention suppresses the growth of bacteria, and since bacteria do not grow even when water supply is stopped, it is possible to perform water supply work without having to waste water when starting water supply after water supply is stopped. The purpose of the present invention is to provide a water purifier that has a simple structure and can be manufactured inexpensively without clogging, and that is highly economical.

(Means for Solving the Problems) The present invention relates to a cylindrical water purification container (cartridge) 1 made of plastic, metal or other material and having a circular shape, an elliptical shape, a quadrangular shape, a polygonal shape, or any other suitable shape. A water purification material 3, which is provided so as to penetrate the water pipe 2 and has a sterilizing power around the water pipe 2,
For example, a water purifying material 3 such as special activated carbon in which pure silver is impregnated into activated carbon is provided to fill the water purifying material 3 into the water purifying container 1, an upper filter 4 is provided at the upper and lower ends of the water purifying container 1, and a lower filter 5 is provided at the lower end thereof An upper lid body 8 and a lower lid body 9 each having an upper water passage chamber 6 and a lower water passage chamber 7 formed outside the upper and lower filters 4 and 5 are fixed to the upper and lower ends of the water purification container 1, respectively.
The lower end of the water pipe 2 communicates with the lower water passage chamber 7, and the upper water passage chamber 6
Is provided with a drainage port 10 for discharging water used, and a water supply port 11 for supplying water from a tap is provided at the upper end of the water pipe 2.
A water purifier directly coupled with the water purification container 1 detachably fitted to an outer cylinder 12.

The outer cylinder 12 is made of a strong metal material or plastic, has a locking flange 13 at the upper end, and a locking flange at the lower end.
The closure lid 15 having 14 is provided with the locking collar 1 via the packing 16.
Retainable band 17 that engages with 3 and 14 and engages with removable band 17
To the closing lid 15 to connect and disconnect the connecting pipes 18 and 19 for water supply and drainage.
Is provided.

Further, since the water supply port 11 and the drainage port 10 can be used in reverse, it is possible to supply water from the drainage port 10 and drain water from the water supply port 11.

(Operation) In the present invention, since the vertical water passage 2 is provided in the cylindrical water purification container 1, from the tap of the water supply, through the rubber, plastic, and other hoses, from the water supply port 11 to the lower end opening of the water pipe 2. After entering the lower water passage chamber 7, the water in the lower water passage chamber 7 passes through the lower filter 5 having a large number of water passage holes, and enters the water purification material 3 made of, for example, special activated carbon having a sterilizing power to sterilize and chlorine. (Chalk) is removed, and purified water enters the upper water passage chamber 6 through the upper filter 4 having a large number of water passage holes, and directly enters from the upper water passage chamber 6 through the drain port 10 of the upper lid 8. , Fill the container with water. Or connection pipe for drainage
Water is poured from 19 into a container that uses water, and the water that has been sterilized and purified is used for drinking or cooking.

In the present invention, tap water is directly introduced into the water pipe 2, and then the water is supplied to the water purifying material 3. Therefore, in the route from the water pipe 2 to the water purifying material 3, the gap C as shown in FIG. Since there is no room to pass through, the water supply is stopped, and the water in the submerged water remains in the water purification container 1, so that the growth of bacteria can be prevented. Since water containing bacteria does not come out even if water supply is started for a long time after the water supply is stopped, it is not necessary to discard the water that had accumulated before water supply, and water supply can be started immediately, and purified, high-quality water Can be used for drinking or cooking.

It should be noted that water is supplied from the drainage port 10, water is put in the upper water passage chamber 6, water is supplied to the water purification material 3 through the upper filter 4, and the water purification material 3
The water purified by the above can be used for drinking or cooking by raising the inside of the water pipe 2 through the lower filter 5 and the lower water passage 7 and discharging it to the outside from the water supply port 11.

The water purification container 1 can be made of plastic, metal, or the like, but the water purification container 1 (cartridge) is detachably fitted to the outer cylinder 12 made of strong metal or hard plastic, and thus has a large durability. The outer cylinder 12 can be used as it is, and the water purification container 1 inside can be replaced with a new one.

(Embodiment) According to the present invention, a water pipe 2 is provided inside a tubular water purifier 1 and a water purifying material 3 is filled into the water purifier 1 while the water pipe 2 is covered. Filters 4 and 5 at the top and bottom
And upper and lower lids 8 and 9 in which water passage chambers 6 and 7 are formed outside the filters 4 and 5, respectively, are fixed to the upper and lower ends of the water purifying container 1, and the lower end of the water passage 2 is a lower water passage. Directly connected to the water supply, characterized by being penetrated into the chamber 7, the drainage port 10 provided in the upper water passage chamber 6, the water supply port 11 provided in the water passage pipe 2, and the water purification container 1 being detachably fitted to the outer cylinder 12. It is a water purifier.

(Effect of the Invention) As described above, the present invention prevents tap water from being directly supplied into the water purification container 1 without the water of the tap water passing through the gap between the water purification container 1 and the outer cylinder 12 and preventing the growth of bacteria. The purified tap water can be used hygienically, and since it does not use a bacteria-cutting membrane as in the past, it does not cause clogging during purification work and can be used for a long period of time. Since there is no growth of bacteria or growth of bacteria in the accumulated water after stopping the water supply, there is no need to waste water when starting water supply after stopping water supply, so there is also a water saving effect, and this structure is also simple and inexpensive to manufacture. In addition, there is almost no space between the water purification container 1 and the outer cylinder 12, so that the water purification container 1 is sufficiently protected by the outer cylinder 12 and the durability is large.
