動的に水の流入口が開口するという利点がある。2. Description of the Related Art Conventionally, a filter using activated carbon has been frequently used for filtering drinking water. In some of such filters, the water inlet is blocked by a water-soluble membrane in order to prevent activated carbon from spilling from the water inlet before the filter is connected to the water supply channel. If the water inlet is closed by a water-soluble film, there is an advantage that when the water is connected to the water supply channel and the water flows, the water-soluble film is melted and the water inlet is automatically opened.

ないという問題点があった。Problems to be Solved by the Invention However, the above-mentioned conventional filter has a problem that a leak test for testing whether a pinhole is opened in the filter cannot be performed because the water inlet is blocked by a membrane. Was. In other words, if a pinhole is opened in the filter, water will leak when water is passed, so it is necessary to test whether the pinhole is opened. In this test, the entire filter was immersed in water while pushing air from the water inlet with the water outlet closed, and the presence or absence of pinholes was determined by whether or not bubbles came out from the outer surface of the filter. Checking. However, if the water inlet is blocked, there is a problem that air cannot be pushed in from the water inlet.

の通過を防ぐことのできる微細な穴を多数有している。In FIG. 1, reference numeral 1 denotes a lower casing, which forms a filtration cartridge together with the upper casing. Reference numeral 3 denotes an inlet provided in the lower casing, and reference numeral 4 denotes an outlet provided in the upper casing. Reference numeral 5 denotes a net provided at the lowermost part of the lower casing 1, which blocks leakage of the granular activated carbon 6 into the inlet 3. Reference numeral 7 denotes a net, which prevents mixing of the granular activated carbon 6 and the powdered activated carbon 8. Reference numeral 9 denotes a leak-proof membrane for activated carbon powder, which is made of a water-soluble material such as starch, has cuts 10 and is mounted on the net 7. Numeral 11 denotes a hollow fiber membrane made of a polymer material, which has a large number of fine holes that can prevent the passage of bacteria.
以上のように構成された本発明のろ過器について、以
下その製造法を説明する。The method for producing the filter of the present invention configured as described above will be described below.

シング１とを互に接着や溶着によって結合する。First, the net 5 is attached to the lower casing, and then the granular activated carbon 6 is charged, and the net 7 is put on the granular activated carbon 6. The leak prevention film 9 is mounted thereon. Also upper casing 2
The upper casing 2 and the lower casing 1 are bonded to each other by bonding or welding.

か検査する。Thereafter, the outlet 4 is plugged and compressed air is introduced from the inlet 3. Then, the compressed air is supplied to the granular activated carbon 6 and the leakage prevention film 9.
Through the cut 10 in the upper casing 2. In this state, it is immersed in water and inspected for leakage from the joint between the upper casing 2 and the lower casing 1.
次に本発明のろ過器について、以下その使用法を説明
する。Next, the usage of the filter of the present invention will be described below.

そして水は粉状活性炭８を巻き上げて、粉状活性炭８に
よってさらに臭いや不純物を除去されて、中空糸膜11を
通過して流出口９より外に排出される。First, the inflow port is connected to a water supply channel, and when water flows, the water passes through the granular activated carbon 6 to remove dust and odor, and reaches the leakage prevention film 9. The water passes through cut 10. As a result, the leak prevention film 9 comes into contact with water from both sides and is quickly dissolved in water.
Then, the water winds up the powdered activated carbon 8, and the odor and impurities are further removed by the powdered activated carbon 8, and the water passes through the hollow fiber membrane 11 and is discharged from the outlet 9.

中に水が滞留すると滞留水の中に細菌が繁殖することが
ある。このような状態になっても中空糸膜11によって細
菌はろ過され、流出口９より出ることはない。Even if the calcium is dissolved in the water supplied to the water supply channel, the calcium is removed by the activated carbon. Therefore, if water stays in the filter for a long time, bacteria may propagate in the stagnant water. Even in such a state, the bacteria are filtered by the hollow fiber membrane 11 and do not exit through the outlet 9.
