Conventionally, as this type of water purifier cartridge, a cartridge configured to purify raw water by filling a filter with a filter medium such as granular activated carbon and passing the raw water through the filter is known. In this cartridge for water purifier, foreign substances contained in raw water such as tap water are removed, and at the same time, calcite is also removed, so that germs can easily propagate in the purified water.
[0003]
In order to deal with such problems, a water purifier cartridge has also been proposed in the past, in which granular activated carbon is filled with sterilized activated carbon coated with a sterilizing material such as silver or a silver compound, and raw water is passed through this sterilized activated carbon. Has been. In this water purifier cartridge, when raw water passes through the sterilized activated carbon and is purified, silver ions are eluted from the sterilized activated carbon into the purified water, and the propagation of germs is suppressed.
[0004]
By the way, in this water purifier cartridge, if the granular sterilized activated carbon is packed at a high density, the sterilized activated carbon is fixed in the filtration part or a water supply is formed. The contact area of the treated activated carbon decreases, and the elution amount of silver ions is remarkably reduced. For this reason, a cartridge for a water purifier is also conventionally proposed in which granular sterilized activated carbon is accommodated in a casing while securing a predetermined space, and the sterilized activated carbon is moved by water flow including fluid dispersion. .
[0005]
[Problems to be solved by the invention]
However, in this conventional water purifier cartridge, since the activated sterilized activated carbon is granular, the carbonaceous matter is separated from the initial activated carbon, and the purified water may be colored black. .
[0006]
The present invention has been made paying attention to such problems existing in the prior art. The objective is to provide the cartridge for water purifiers which can sterilize purified water effectively and can prevent a possibility that purified water will be colored black.

DETAILED DESCRIPTION OF THE INVENTION
EMBODIMENT OF THE INVENTION Below, one Embodiment which actualized this invention to the water purifier for cold water supply machines, such as a cold tea supply machine, is described based on drawing.
[0014]
As shown in FIG. 1, the container body 11 of this water purifier is formed in a bottomed cylindrical shape, and a lid 12 is detachably attached to a top opening of the water purifier via a packing 13 via a packing 13. At a position deviated from the center of the top wall of the lid 12, a cylindrical inflow port 15 for allowing raw water such as tap water to flow in is disposed. A cylindrical outlet 16 for allowing the purified water to flow out is disposed at the center of the top wall of the lid 12, and a female screw 16 a is formed on the inner peripheral surface thereof.
[0015]
A water purifier cartridge 17 is detachably attached to the lower surface of the lid 12 and is accommodated in the container main body 11 with predetermined gaps in the upper, lower and circumferential side portions. That is, a cylindrical outlet 18 protrudes from the center of the upper end of the water purifier cartridge 17, and a male screw 18a is formed on the outer peripheral surface thereof. Then, by screwing the male screw 18a with the female screw 16a, the outlet 18 of the water purifier cartridge 17 is connected to the outlet 16 of the lid body 12, and the water purifier cartridge 17 is suspended and fixed to the lid body 12. ing.
[0016]
As shown in FIG. 2, the water purifier cartridge 17 includes a filtering unit 19, a case 20 attached to the upper end of the filtering unit 19, an upper lid 21 attached to the upper end of the case 20, and a filtering unit. 19 and a lower lid 22 attached to the lower end portion of 19. The outlet 18 is integrally formed so as to protrude from the center of the upper surface of the upper lid 21.
[0017]
The filtration unit 19 is composed of fibrous activated carbon formed in a cylindrical shape. And the raw water which flowed in the container main body 11 from the said inflow port 15 is made to flow the filtration part 19 from the outer peripheral side to the center communicating path 26, and thereby the foreign material, a salt, etc. which are contained in raw water are removed, and purified water is removed. It is supposed to be formed.
[0018]
As shown in FIGS. 2 and 3, the case 20 is formed of a synthetic resin into a bottomed cylindrical shape, and a communication hole 27 communicating with the communication path 26 is formed on the bottom surface thereof. A substantially disc-like cover plate 28 having a large number of through holes 28a is fitted into the upper end opening of the case 20, and a holding pin 29 that constitutes guide means and restricting means projects from the center of the lower surface. .
[0019]
A plurality of disk-like activated carbon fiber sheets 30 in the case 20 block the water flow in the direction perpendicular to the water flow direction in the case 20 so as to be positioned in the flow path downstream of the raw water with respect to the filtration unit 19. It is arranged to extend. Each activated carbon fiber sheet 30 is configured by mixing activated carbon having a small particle diameter in a fiber bundle forming the sheet, and the granular activated carbon is coated with a sterilizing material made of silver or a silver compound. An insertion hole 30 a is formed at the center of each activated carbon fiber sheet 30. A plurality of activated carbon fiber sheets 30 are superposed via cylindrical spacers 31 as holding means, and the insertion holes 30a are inserted into the holding pins 29, whereby each activated carbon fiber sheet 30 is placed in a case. 20 is disposed in a state where a predetermined gap is maintained.
[0020]
Furthermore, in this state, the purified water purified by the filter medium 25 flows into the case 20 from the insertion hole 30a and passes through the inside and outside of each activated carbon fiber sheet 30, thereby, as shown by a chain line and a solid line in FIG. Those activated carbon fiber sheets 30 are moved in a water flow, and are bent and moved in the vertical direction. In this case, the spacer 31 on the holding pin 29 allows the curved movement of the activated carbon fiber sheets 30 and maintains the spacing between the activated carbon fiber sheets 30. Further, the movement of each activated carbon fiber sheet 30 in the radial direction is restricted by the holding pins 29. Then, sterilizing material ions such as silver ions are eluted from each activated carbon fiber sheet 30 into the purified water, and the purified water is sterilized.
[0021]
Next, an operation of the water purifier including the water purifier cartridge 17 having the above-described configuration will be described.
Now, when this water purifier is installed in a cold water feeder such as a cold tea feeder, raw water such as tap water is introduced from the inlet 15 of the lid body 12 and filled into the container body 11. . In this state, when a water supply valve in a water supply pipe (not shown) connected to the outlet 16 is opened, the raw water in the container body 11 passes through the filter medium 25 and flows into the communication passage 26, and the raw water is purified. Is done.
[0022]
Thereafter, the purified water that has been purified flows into the case 20 from the communication path 26 through the insertion hole 30a, passes through the plurality of activated carbon fiber sheets 30, and flows out from the outlet 16 into the water supply pipe. At this time, since each activated carbon fiber sheet 30 is maintained at a mutual interval by the spacer 31 under the movement restriction by the holding pin 29, the activated carbon fiber sheet 30 is curved and moved so as to fluctuate in the vertical direction by the water flow. Then, the purified water is further purified by the activated carbon fiber sheet 30 and sterilizing material ions such as silver ions are effectively eluted from the activated carbon fiber sheet 30 into the purified water to sterilize the purified water. In this case, since the activated carbon fiber sheet 30 is used in the cartridge for the water purifier, there is no possibility that the carbon is eluted in the purified water and the purified water is colored black.
[0023]
Therefore, according to this embodiment, the following effects can be obtained.

For this reason, after the raw water is purified by passing through the filtration unit 19, when the purified water passes through the activated carbon fiber sheet 30, the sterilizing material ions are eluted from the activated carbon fiber sheet 30. Therefore, the purified water can be effectively sterilized, and the possibility that various germs propagate in the purified water can be reliably suppressed. In addition, since the activated carbon fiber sheet 30 carrying the sterilizing material is used, unlike the conventional configuration in which the sterilized activated carbon obtained by coating the sterilizing material on the granular activated carbon is filled in a predetermined section, the carbonaceous material is eluted. Therefore, it is possible to reliably prevent the purified water from being colored black.
[0025]
In the water purifier cartridge 17, the activated carbon fiber sheet 30 is formed in a disc shape, and the holding pin 29 is inserted into the insertion hole 30 a at the center thereof so as to extend in a direction orthogonal to the water flow. ing. The holding pin 29 restricts movement in a direction other than the water flow direction. Therefore, the activated carbon fiber sheet 30 can be prevented from clumping or being folded in one place in the case 20, effectively increasing the surface area with respect to the water flow, and effectively sterilizing material ions from the activated carbon fiber sheet 30. It can be eluted and sterilization can be utilized.
[0026]
In the water purifier cartridge 17, a plurality of disc-shaped activated carbon fiber sheets 30 are arranged with a predetermined gap being held via a spacer 31. For this reason, purified water passes through a plurality of activated carbon fiber sheets 30 in order, sterilization material ions are surely eluted from the activated carbon fiber sheets 30, and the purified water can be effectively sterilized.
[0027]
(Example of change)
In addition, this embodiment can also be changed and embodied as follows.
