That is, since the impurities in the raw water 7 cannot be sufficiently filtered only by the granular activated carbon 931, the impurities are filtered using the hollow fiber membrane 932. However, the hollow fiber membrane 932
Since the water flow resistance is high, the raw water 7 cannot pass through the hollow fiber membrane 932 only by the head pressure of the raw water 7. Therefore, in purifying the raw water 7, some pressure must be applied to the raw water 7 to pass through the hollow fiber membrane 932. Cleaning is inconvenient.

In No. 32, the bacteria in the raw water 7 cannot be sterilized. Therefore, as described above, the raw water 7 is sterilized by adding sodium hypochlorite to the raw water. However, when drinking the purified water 71 obtained by adding the chemicals as described above, it is necessary to check whether the added chemical is sodium hypochlorite, and whether the added amount is appropriate. It is necessary to confirm. Therefore, in the conventional portable water purifier 9 described above, since chemicals such as sodium hypochlorite are handled,
The cleaning operation is complicated.

What is claimed is: 1. A portable water purifier having a water receiver that receives purified water that has passed through a body, and an ultraviolet sterilizer disposed in the water receiver. A simple portable water purifier is characterized in that a part of a number of intersecting intersections is joined by a binder and the activated carbon fibers contact each other to form an infinitely small gap.

体の通水抵抗を低く保つことができる。Next, the operation of the present invention will be described. In the simple portable water purifier of the present invention, the activated carbon fiber molded body in the filtration water tank is formed by joining a part of the crossing portion between activated carbon fibers with a binder. For this reason, the porosity of the activated carbon fiber molded body is larger than when the activated carbon fibers are simply laminated. In addition, since the binder functions as a buffer, it is possible to prevent the activated carbon fiber molded article from buckling with the natural flow of raw water. Therefore, the water resistance of the activated carbon fiber molded article can be kept low.

できる。[0010] Therefore, the raw water can flow naturally through the activated carbon fiber molded article by the natural flow only by the head pressure, so that the raw water is not forced down using, for example, a hand pump. The purification operation can be easily performed.

る。[0011] Further, the binder is bonded to a part of the intersection of the activated carbon fibers. Therefore, among the infinitesimal gaps formed by the activated carbon fibers contacting each other, the infinitesimal gaps that the binder closes are about several percent of the total infinitesimal gaps of the activated carbon fiber molded body. Similarly, among the pores for trapping fine particles on the surface of the activated carbon fiber, there are almost no pores closed by the binder. Therefore, the fine particle capturing property of the activated carbon fiber molded body can be ensured.

作を行うことができる。Further, since bacteria in the raw water can be sterilized by ultraviolet sterilizing means, chemicals such as sodium hypochlorite are not added to the raw water. Therefore, there is no need to check the type and amount of the above-mentioned chemicals, and the purification operation can be easily performed.
【００１３】上述のごとく，本発明によれば，自然流下

成することができるという効果がある。Next, it is preferable that the binder is a hot-melt resin having a melt viscosity of a predetermined value or more. In this case, there is an effect that the infinitesimal gap can be easily and reliably formed at the intersection of the activated carbon fibers.

える場合には，上記バインダーと上記活性炭素繊維との
なじみが悪くなり，結合力不足により上記無限小間隙を
形成することが困難になるという問題がある。The binder preferably has a melt viscosity of 20,000 to 50,000 centipoise. When the melt viscosity is less than 20,000 centipoise, when the binder is melted, the binder is liable to spread to the intersections between the activated carbon fibers and the surface of the activated carbon fibers. Therefore, the ratio of the infinitesimal gap and the pores of the activated carbon fiber closed by the binder increases. For this reason, the activated carbon fiber molded body has a reduced ability to trap fine particles. On the other hand, if the melt viscosity exceeds 50,000 centipoise, there is a problem that the affinity between the binder and the activated carbon fiber deteriorates, and it becomes difficult to form the infinitesimal gap due to insufficient bonding force.

プを点灯することで確実に充分な殺菌を行った浄水を得
ることができる。Next, it is preferable that the ultraviolet sterilizing means is an ultraviolet irradiation lamp or a photocatalyst. When the ultraviolet sterilizing means is an ultraviolet irradiation lamp, for example, by installing a timer or the like, the ultraviolet irradiation lamp can be automatically turned off. Therefore, the purifying operation can be performed more easily.
In addition, since the UV irradiation time required for sterilization can be set,
By turning on the ultraviolet irradiation lamp until the set time elapses, it is possible to surely obtain purified water that has been sufficiently sterilized.
【００１７】また，上記紫外線殺菌手段が光触媒である

Having a hydroxyl radical. Therefore, the simple portable water purifier can be used without a power source or a battery if weak ultraviolet rays are present. Note that the photocatalyst and the ultraviolet irradiation lamp can be used in combination.

And a binder made of a hot-melt resin having a melt viscosity of not less than a predetermined value in water, dried to form a laminate, and then heated at 120 to 150 ° C. to melt the binder. Then, a part of a large number of intersecting portions where the activated carbon fibers intersect with each other is joined to form a method for producing an activated carbon fiber molded body.

う。When the ratio of the binder to the activated carbon fibers is less than 3% by weight, it is impossible to prevent the activated carbon fiber molded article from buckling due to the natural flow of the raw water. Therefore, the water resistance of the activated carbon fiber molded body cannot be kept low. For example, when the simple portable water purifier is used for a long term, the raw water can be allowed to flow naturally only by the head pressure. It may disappear. on the other hand,
When the proportion of the binder is more than 5% by weight, the infinitesimal voids closed by the binder are not limited to a few percent of the total infinitesimal voids of the activated carbon fiber molded article, and the infinitesimal voids of the activated carbon fiber molded article are not limited to several percent. The particle capturing property is reduced.

Therefore, buckling of the activated carbon fiber molded body cannot be prevented. On the other hand, when the heating temperature exceeds 150 ° C., there are problems such as deterioration and deterioration of the binder.

Stored in 1. Next, after the natural flow of the raw water 7 is completed, the power plug 522 is connected to an existing power supply (not shown), and the ultraviolet irradiation lamp 51 is turned on. The ultraviolet light emitted from the ultraviolet irradiation lamp 51 itself kills the bacteria in the purified water 71 and simultaneously removes the bacteria from the purified water 7.
1 produces a hydroxyl radical having a bactericidal effect. In addition, since the photocatalyst is irradiated with a sufficient amount of ultraviolet light, the amount of the generated hydroxy radical is increased, and the bacteria in the purified water 71 are surely sterilized.

Therefore, the water resistance of the activated carbon fiber molded body 3 can be kept low. Therefore, the raw water 7 can be allowed to flow naturally through the activated carbon fiber molded article 3 by natural flow only with the head pressure, without forcibly flowing down the raw water 7 using a hand pump or the like.

Therefore, among the infinitesimal gaps 6 formed by the activated carbon fibers 31 contacting each other, the infinitesimal gaps 6 in which the binder 32 is closed are the number of the infinitesimal gaps 6 of the activated carbon fiber molded body 3. %. Similarly, among pores (not shown) for trapping fine particles on the surface of the activated carbon fibers 31, there are almost no pores closed by the binder 32. Therefore, it is possible to secure the fine particle capturing property of the activated carbon fiber molded body 3.
