FIG. 2 shows an example of a conventional water purifier 1. The water purifier 1 comprises a main body case 2 and a cartridge 5 in which activated carbon 3 and hollow fiber membranes 4 are filled. The water flowing from the inflow port 6 passes between the main body case 2 and the cartridge 5, flows into the cartridge 5 from the introduction port 7 on the lower surface side of the cartridge 5, passes through the activated carbon 3 and the hollow fiber membrane 4, and then flows out. It flows from 8 to the spout. By contact with activated carbon 3, odor components such as chlorine odor (chlorine content) and organic substances are adsorbed by the particles of activated carbon 3 and removed. Then, by passing through the hollow fiber membrane 4, iron rust, mold, various bacteria, etc. Fine turbidity is removed and delicious water is obtained.

FIG. 3 shows an electronic bactericidal water purifier 9 previously developed by the present applicant and filed in Japanese Patent Application No. 63-022845. This water purifier 9 has a hollow cartridge case 10 provided with a tap water introduction pipe 11 at the upper portion thereof and a discharge pipe 12 at the lower portion thereof. Then, a sheet-shaped material of activated carbon fibers 13 formed in a spiral shape is arranged inside the case 10, and the positive electrode and the negative electrode of the battery 14 are connected to both ends of the activated carbon fibers 13 by wiring. .. In this water purifier 9, a voltage is applied from the battery 14 to the activated carbon fiber 13, so that various bacteria in the case 10 are collected and attached to the surface of the activated carbon fiber 13, and then the attached state. The coenzyme in the various bacteria will be oxidized by the voltage. Then, the substance metabolism function of the cell membrane of the miscellaneous bacteria is disturbed, and the killing and propagation of the miscellaneous bacteria can be prevented, and as a result, delicious water can be obtained.

[0005]

[Problems to be solved by the device]

 However, in the water purifier 1 shown in FIG. 2, only the bacteria contained in the tap water are filtered by the hollow fiber membrane 4, so that the bacteria multiply by that amount when the unused time becomes long, and Carcasses were deposited on the hollow fiber membranes 4 as residues after the filtration treatment, and there were drawbacks that the water rotted and gave off an offensive odor, and the hollow fiber membranes 4 were clogged.

Further, in the water purifier 9 previously filed by the applicant of the present invention shown in FIG. 3, activated carbon fibers 13 can remove odorous components such as chlorine odor (chlorine component), but iron rust Components such as fine turbidity are discharged as they are without being filtered, and it is difficult to obtain clean water.

 SUMMARY OF THE INVENTION The present invention is an improved solution of the above-mentioned problems in view of the above problems, and it is an object of the present invention to provide a water purifier capable of removing both odorous components and turbid components and discharging delicious and clean water. Therefore, the means adopted by the present invention to solve the above-mentioned problem is to provide an electronic bacteriostatic mechanism for bacteriostatically applying a weak voltage on the upstream side of the water purifier body. The water purifier is characterized in that an activated carbon fiber and a hollow fiber membrane are arranged on the downstream side of the mechanism.

[0008]

[Action]

 In the water purifier of the present invention, when a weak voltage is applied to the water in the water purifier by the electronic antibacterial mechanism, the negatively charged bacteria are pulled on the surface of the activated carbon fiber at the positive electrode. You will come to gather together. Then, the coenzyme in the miscellaneous bacteria is oxidized, the metabolic function is impaired, and its reproduction is prevented. In this way, the water in the water purifier comes into contact with the activated carbon fibers on the downstream side of the bacteriostatic mechanism in the sterilized state, and the chlorine odor (chlorine component) is adsorbed. Further, by passing through the hollow fiber membrane on the downstream side, filtration is performed and iron rust and fine turbidity contained in tap water are removed. Therefore, it is possible to provide clean and delicious water with no odor or turbidity.
