[Technical field to which the invention belongs]

 The present invention relates to a water purifier attached to a tap of a water supply.

[0002]

[Problems to be solved by the device]

 Conventionally, as this type, a water purifier that stores activated carbon and removes the odor of chlorine by utilizing the adsorptivity and absorption of odor molecules of activated carbon has been known. In such a water purifier that is attached to the tap of a tap using activated carbon, the water purifier itself is relatively small and its volume is limited, so a large amount of activated carbon cannot be stored, resulting in poor purification performance. There was a problem. Furthermore, in such a case, there is a possibility that various bacteria may propagate on the activated carbon, which is a sanitary problem.

As one means for solving such a problem, it is possible to use copper. This utilizes the dechlorinating action, sterilization and antibacterial action of copper. This work is due to the trace metal action of copper.

However, since the water purifier itself attached to the tap of a tap is relatively small and its volume is limited, when a copper plate or the like is provided, the contact area between tap water and copper is small, There was a problem that the trace metal action of copper could not be effectively exerted.

Therefore, an object of the present invention is to provide a sanitary water purifier capable of surely dechlorinating and antibacterial and sterilizing effects of bacteria.

At this time, due to the elasticity of the ribs 12, the inner cylindrical portion 10 can be attached to the faucet 8 in a watertight manner. Then, when water is made to flow from the faucet 8, the water first hits the diffusion plate 14A and diffuses, then passes through the small holes 14 and reaches the upper layer 17 of the copper 16. When passing through the upper layer 17 of the copper 16, water is subjected to antibacterial and sterilizing actions by the trace metal action of the copper 16 and further removes chlorine. The water treated in this way then passes through the upper layer 18 of activated carbon. In this case, the odorous molecules of activated carbon are adsorbed and absorbed. Further, the water passes through the middle layer 19 of the copper 16 and the lower layer 21 of the copper 16 along the water passage 6 to be antibacterial and sterilized by the trace metal action of the copper 16, and further removes chlorine. Further, the activated carbon has a function of adsorbing and absorbing odorous molecules and the like through the lower activated carbon layer 20. The water purified in this way is discharged through the net 22.

When the residual chlorine removal effect test of the purified water was carried out as described above, the residual chlorine of the tap water at the inlet 4 was 0.4 ppm, but the water purified by the water purifier after 30 minutes, No residual chlorine was detected (less than 0.05 ppm) in either case after 120 minutes.

In addition to the antibacterial and sterilizing effects, it is hygienic without the possibility that bacteria will propagate in the case 1.

Further, in the first embodiment, according to claim 2, since the fibrous copper 16 is provided in the form of a non-woven fabric, the fibrous copper 16 is densely provided and the copper 16 The surface area of the copper 16 is increased, the contact area between the tap water and the copper 16 is increased, and the trace metal action of the copper 16 enables effective desalination, antibacterial, and sterilization actions.

Further, in the first embodiment, corresponding to claim 3, the diameter of the fibrous copper 16 is set to be 10 to 30 μm, so that the volume of the case 1 is relatively small. Even if it has a large capacity, it accommodates an extremely large number of fibrous copper 16 and increases the contact area between tap water and copper 16, and the trace metal action of copper 16 provides a single layer effect of dechlorination, antibacterial action, and sterilization action. Can be achieved.

Further, in the first embodiment, in accordance with claim 4, the water passage 6 of the case 1 having the inlet 4 at the upper portion and the outlet 5 at the lower portion is provided with the fibrous copper 16 in the form of a non-woven fabric. By providing the layers 17, 19 and 21 and the activated carbon layers 18 and 20, even if the volume of the case 1 is relatively small, a very large number of fibrous coppers 16 can be accommodated and used as tap water. The contact area of copper 16 is increased and the trace metal action of copper 16 makes it possible to more effectively achieve dechlorination, antibacterial and sterilization actions, and the activated carbon layers 18 and 20 adsorb and absorb odorous molecules. In addition, the bacteria in the activated carbon layers 18 and 20 are suppressed by the trace metal action of the copper 16, and a sanitary water purifier can be provided.

Next, a second embodiment will be described with reference to FIGS. 3 and 4. The same parts as those in the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted. In the second embodiment, a large number of copper 31 having a diameter of 10 to 30 μm and a length of, for example, about 10 to 100 mm is formed into a non-woven fabric, which is formed from a net body such as stainless steel. It is provided in the case 1 while being housed in the water-permeable container 32. The housing 32 can be replaced by removing the cap 3, the mounting packing 9, and the diffusion plate 14A.

Therefore, when water is made to flow from the faucet 8, in the water passage 6 from the inlet 4 to the outlet 5, the demineralizing action, antibacterial action, and sterilizing action can be performed by the trace metal action of the copper 31.

As described above, in the second embodiment, in accordance with claim 5, the water passage 6 that connects the inlet 4 and the outlet 5 provided in the case 1 is provided with a fiber copper 31 accommodated therein. By providing the water-capable storage 32, the fibrous copper 31 is densely provided to increase the surface area of copper, and the contact area between the tap water and the copper 31 is increased. The dechlorinating action, antibacterial action, and sterilizing action can be achieved, and hygiene is possible without the possibility of germs in the case 1.

In addition, in the second embodiment, according to claim 6, the housing 32 is detachably provided in the case 1 by removing the cap 3, the mounting packing 9, and the diffusion plate 14A. As a result, the copper 31 becomes a cartridge type and can be easily replaced.

It should be noted that the present invention is not limited to the above-described embodiment. For example, in the first embodiment, the copper layer has three layers and the activated carbon layer has two layers, but the copper layer and the activated carbon layer have one layer. It is also possible to make various modifications such as using two layers of copper and one layer of activated carbon between them.
