During this period, the hollow fiber membrane 53 is sterilized, and the antibacterial activated carbon 55 is deodorized to obtain sanitary safe and odorless delicious mineral water.

By the way, in the conventional hollow fiber membrane filter, the antibacterial activated carbon is not arranged in the cap, that is, on the downstream side of the hollow fiber membrane, and the mineral water sterilized by the hollow fiber membrane is directly attached to the mounting leg. After that, it was sent to the water supply pipe. Therefore, the odor of the adhesive for fixing and sealing the hollow fiber membrane to the case and the odor of the hydrophilic treatment agent for the hollow fiber membrane may be mixed in the mineral water. In this embodiment, since the antibacterial activated carbon 55 is arranged on the downstream side of the hollow fiber membrane 53 to deodorize, the mineral water does not emit an odor.

Next, the operation of this embodiment constructed as described above will be described. First, the upper lid 3 is opened, and tap water is injected into the storage container 6 from the upper portion until the full scale 19 is reached, the upper lid 3 is closed, and the power switch of the operation panel 4 is turned on. As a result, the circulation pump 14 is driven, and the storage container 6
The water inside is sent from the second circulation port 13 through the first circulation port 12 into the mineral water production filter 30. The water sent into the mineral water production filter 30 passes through this over a long time (for example, 20 minutes), and the jet port 43
Is jetted into the storage container 6 and then sent again to the mineral water production filter 30 for circulation. The circulation pump 14
There is a risk that the water in the mineral water production filter 40 will flow back to the first circulation port 12 side when the water circulation is stopped by stopping the flow of water. However, in this embodiment, the check valve 35 closes the water passage. Therefore, there is no such fear.

In this case, the water ejected from the ejection port 43 comes into contact with the air and the dissolved oxygen increases, so that the tasty and refreshing mineral water is obtained, so that the mineral water producing filter 30 can be obtained.
It is desirable to position the jet port 43 of the above above the full scale 19. Meanwhile, residual chlorine and impurities contained in tap water are removed, minerals such as calcium, magnesium, sodium and potassium are eluted, and delicious mineral water is produced.

When drinking minel water, the switch of the operation panel 4 is operated to operate the water supply pump 20. Thereby, the mineral water in the storage container 6 is sent from the discharge port 15 through the connection port 17 to the hollow fiber membrane filter 45, is sterilized and deodorized, and is discharged from the connection port 18 through the water supply pipe 23 and the desired water supply port 22. Amount of water is supplied. In this case, there is no particular problem when water is supplied immediately after the circulation pump 14 is in operation or after it is stopped, but when it is left for a while after the mineral water is formed, it does not contain chlorine, and thus bacteria in the air are not contained. May invade and is unsanitary. However, in the present embodiment, since the bacteria are removed by passing through the hollow fiber membrane filter 45 at the time of water supply, there is no such problem and it is extremely hygienic.

In the above embodiment, the water pump 20 and the hollow fiber membrane filter 4 are provided between the discharge port 15 and the water supply port 22.
The hollow fiber membrane filter 4 is shown in FIG.
5, the discharge port 15 and the water supply port 22 are connected to the water pump 2
You may make it connect via 0.

Example 2 When the cold water is circulated in the storage container 6 as described above, dew condensation occurs on the outer periphery of the storage container 6, which drops onto the electrical parts provided below the storage container 6 to insulate it. Failures such as defects may occur. Therefore, in this embodiment, the inner case 5 is arranged on the outer periphery of the storage container 6 with a gap C therebetween.
An air layer is formed between the two by this gap C to have a heat insulating effect. With this configuration, it is possible to keep the water in the storage container 6 cool and prevent the occurrence of dew condensation.

The same effect can be obtained even if the gap C formed between the storage container 6 and the inner case 5 is made airtight or in a vacuum state. Further, by coating the inner surface of the storage container 6 with a fluororesin, it is possible to prevent dew condensation due to its heat insulating effect.

Even if dew condensation occurs on the outer periphery of the storage container 6 for some reason, the dropped water drops flow through the side wall of the waterproof cover 24 to the bottom of the main body case 2 and are discharged from the drain port 27. It does not adversely affect the parts.

Embodiment 3 As described above, the water in the storage container 6 passes through the mineral water producing filter 30 for a long time (for example, 20 minutes) by the circulation pump 14 and is circulated. So high pressure is needed. Therefore, in this embodiment, as shown in FIG. 10, the motor 56 drives the gear pump 57. However, when this is done, vibration noise is inevitably generated, so in this embodiment, the entire circumference of the motor 56 was covered with one rubber cushion 58 to reduce vibration noise.

As shown in FIG. 11, this rubber cushion 58 is provided with flanges 60a and 60b on the opening side of a substantially C-shaped main body 59, respectively.
On the opposite side of 60b, part of the main body 59 is cut and raised,
The tongue piece 61 is provided at substantially the same height as the flange 60b. Then, as shown in FIG. 10, the main body 59 covers the outer periphery of the motor 56 of the circulation pump 14, and the screw insertion holes 62 provided in the flanges 60 a and 60 b and the tongue piece 61.
The screws 63 are inserted into the and are fixed to the waterproof cover 24 via the spacers 64, respectively. With this configuration, most of the vibration noise of the circulation pump 14 is absorbed by the rubber cushion 58, and the generation of noise can be suppressed.
