The lower part of the bar 5 is detachably attached to the base 7.

[0011] The extraction cartridge main body 5 is attached to and detached from a pedestal 9 supported by a frame (not shown). The extraction cartridge main body 5 contains a mineral extract. For example, a medium cylindrical mineral liquid supply device 11 to which liquid M is supplied is provided on the left side. On the right side of this mineral supply device 11, gaps S are provided at appropriate intervals. Activated carbon layer 13, ion exchange resin layer 15, and ceramic layer are arranged in order from bottom to top. 17, a first chamber 19, a fiber layer 21 and a mineral-containing layer in order from the bottom to the top. An extraction cartridge 27 is provided which consists of a second chamber 25 with a stone layer 23. Ru. This extraction cartridge 27 is separated into a first chamber 19 and a second chamber by a separation plate 29. 25 are separated, and an opening 31 is formed in the upper part of the separation plate 29.

0012 In the center of the pedestal 9 is an extraction cartridge for extracting raw water flowing from the raw water supply device. It has a pipe connection part 33 for water supply to the activated carbon layer 13 of the first chamber 19 at 27. A fitting receiving portion 35 is provided. On the right side of the pedestal 9 is an extraction cartridge 2. Pipe connection 3 for drainage for draining the extracted drinking water through 7 to the water storage device A fitting receiving portion 39 having a diameter of 7 is provided.

[0013] On the left side of the pedestal 9, a mineral extract liquid M is supplied from a mineral extract liquid supply device 11. A saucer 41 for receiving the water is provided. The mineral extract liquid M is fed to this saucer 41. A pipe connection portion 43 and a push-up rod 45 for exit are provided. In addition, the pedestal 9 For example, between the fitting receiving part 35 and the fitting receiving part 39, the extraction cartridge main body 3 is located at the front. A detection device such as a limit switch that detects that it is supported by the recording stand 9 A switch 47 is provided.

[0014] The water inlet portion 49 with the packing 49A that is fitted into the fitting receiving portion 35 is connected to the first is formed so as to protrude downward from the chamber 19, and is fitted into the fitting receiving portion 39. A drain port portion 51 with a packing 51A is formed to protrude downward from the second chamber 25. has been done.

[0015] The detection switch 47 is not shown when the extraction cartridge 27 is not set. This serves to prevent the drive pump from operating. In this case, the said drainage A fitting receiving portion 39 having a pipe connecting portion 37 is formed in a receiving hole 53 on the right side wall of the pedestal 9. When the extraction cartridge 27 is set, it is inserted so that it can be slid laterally. The fitting receiving portion 39 is movable.

[0016] Further, the upper end of the tube joint portion 43 provided on the saucer 41 is connected to the mineral liquid supply device 1. 1 faces the extract supply port 55 through which the mineral extract liquid M is supplied, and the A valve body 57 is provided corresponding to the push-up rod 45, and the mineral liquid supply device 11 is connected to the valve body 57. When set on the extraction cartridge main body 3 supported by the pedestal 9, the push-up rod 45 causes the valve body 57 to act and drain the mineral liquid M from within the mineral liquid supply device 11. is supplied to the extract supply port 55.

[0017] With the above configuration, the mineral extract liquid M is supplied from the mineral liquid supply device 11. After being supplied to the supply port 55, it is sent to the saucer 41. Next, from this saucer 41 Mineral extract liquid M is supplied into the saucer of the raw water supply device shown below and mixed with a certain amount of raw water. be done. This mixed liquid is transferred to the extraction chamber by the operation of a drive pump (not shown). The fitting joint 33 of the cartridge 27 is formed in the lower part of the first chamber 19 via the water supply port 49. Impurities are removed in the activated carbon layer 13 containing the activated carbon.

[0018] Next, the mixed liquid is sent to an ion exchange resin layer 15 containing an ion exchange resin agent. The ions are ionized and mixed in the ceramic layer 17 containing granular ceramic. Sufficiently dissolved in liquid. An opening is opened from the ceramic layer 15 to the upper part of the separation plate 29. It is sent through the opening 31 to the mineral-containing stone layer 23 formed in the upper part of the second chamber 25. After the pH is adjusted to approximately 7, the fiber layer 21 formed in the lower part of the second chamber 25 Impurities are removed by filtration with several hundred hollow fiber membranes of, for example, 0.1 μm/filter inside. Then, impurities were removed through the drain port 51 and the pipe connection 37 to a water storage device (not shown). Drinking water containing minerals is temporarily stored.

[0019] As mentioned above, under normal conditions, the extraction cartridge of the extraction cartridge device 1 is connected to the raw water supply device. Drinking water is sent to the water storage device through the cartridge 27, and there is no problem. Each hollow fiber membrane consisting of several hundred fibers contained in the fiber layer 21 is clogged with coarse dirt, etc. There are times when I feel like this.

[0020] For this reason, in this embodiment, for example, a driver having an inner diameter of about 1 to 1.5 mm is used. One end of the drain pipe 57 is opened at the bottom of the fiber layer 21, and this drain The pipe 57 extends in the vertical direction, and is formed within the mineral-containing stone layer 23, for example. It is bent to the left side, passes through the ion exchange resin layer 17, and extends downward from the gap S. The other end of the drain pipe 57 is attached to and detached from the lower surface of the extraction cartridge main body 3. Possibly installed. Extraction cart with one end of this drain pipe 57 attached A hole 59 is formed in the lower surface of the ridge main body 11, and another hole is formed in this hole 59. One end of a pipe 61 is attached, and this pipe 61 passes through the pedestal 9. The other end of the pipe 61 is connected to a tank 63 for raw water.

[0021] With the above configuration, each hollow fiber membrane consisting of several hundred fibers formed in the fiber layer 21 has If it becomes clogged with coarse dirt, water will be drained from the drain port 51 and pipe connection 37 to the water storage device. The flow of feed water becomes poor, and the water pressure below one end of the drain pipe 21 is reduced. higher than usual. Taking advantage of this phenomenon in which the water pressure increases, drain pipe 5 Water is sucked into one end of 9 at high pressure. With the pressure of this sucked water, each inside Coarse dust, etc. that is clogged in the empty fiber membrane is sucked into the drain pipe 59 and drained. The other end of the lane pipe 59 is collected into a raw water tank 63 via another pipe 61. Therefore, it will be recycled and used again. Then, each hollow fiber membrane is filled with When the coarse dirt that was inside is sucked into the drain pipe 61 and removed, it is automatically stored. It will flow to the water system.

[0022] In this way, one end of the drain pipe 59 is placed under the fiber layer 21 of the second chamber 25. and the other end of the drain pipe 59 is opened to the outside to the extraction cartridge 27. As a result, coarse particles are formed in each of the several hundred hollow fiber membranes contained in the fiber layer 21. Even if it is clogged with dirt, it can be easily removed to the outside, preventing the occurrence of strange odors. In both cases, the fiber layer 21 can be used for a longer time than before, and the time for replacing the fiber layer 21 can be extended. can be reduced. In addition, the other end of the drain pipe 57 is connected through another pipe 61. By making it possible to collect the raw water into the raw water tank 63, the water can be recycled and recovered. It is possible to reuse it.

[0023] In addition, although the example in which the inner diameter of the drain pipe 57 is 1 to 1.5 mm has been explained, The drain pipe 57 has a diameter relative to the inner diameter of the second chamber 25 in which the fiber layer 21 is formed. From the viewpoint of water pressure, it is preferable to set the inner diameter to about 1/20±20%.

[0024] Note that this invention is not limited to the embodiments described above, and may be modified as appropriate. By doing so, it can be implemented in other ways. In this example, the drain port The pipe 57 is passed through the gap S and collected into the raw water tank 63 via the external pipe 61. As explained above, the other end of the drain pipe 57 is extracted from the mineral-containing stone layer 23. It is also possible to discharge the liquid to the outside through the output cartridge 27.

[0025]

[Effect of the idea] As can be understood from the explanation of the embodiments above, this invention provides practical innovations. Since the structure is as described in the claim for draft registration, one end of the drain pipe at the bottom of the fiber layer in the second chamber, and the other end of the drain pipe to the extraction cartridge. By opening to the outside, each layer consisting of several hundred fibers contained within the fiber layer Even if the hollow fiber membrane is clogged with coarse dirt, it can be easily removed to the outside, preventing the generation of unpleasant odors. In addition to preventing this, the fiber layer can be used for a longer time than before, and it is easier to replace the fiber layer. The period can be lengthened. Also, connect the other end of the drain pipe to another pipe. Recycle and reuse water by allowing collection into raw water tanks It is possible to do this.
