BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of a water purification cartridge and a water purifier of the present invention will be described in detail below with reference to the drawings. In the following, when simply referred to as a computer, it means the computer described in the first to twelfth inventions. FIG. 1 is a perspective view showing a part of an embodiment of an inorganic filter medium as a cross section, FIG. 2 is a perspective view of an activated carbon layer and an inorganic filter medium, and FIG. 3 is a water purification cartridge of the present invention incorporating an activated carbon layer and an inorganic filter medium. It is a longitudinal cross-sectional view showing an embodiment of.

In FIG. 1, reference numeral 1 denotes an inorganic filter medium, which is composed of a cylindrical support 2 made of water-permeable ceramics and a filter aid layer 3. This inorganic filter material 1 is formed by forming a layer of a filter aid on the outer peripheral surface of the support 2 and then
The filter aid is appropriately solidified by firing at 00 to 1240 ° C. and fixed at the interface with the support 2 to prevent separation of the filter aid layer 3 from the support 2 and collapse of the filter aid layer 3. I'm out.

Examples of the filter aid used here include diatomaceous earth, porous inorganic particles such as zeolite, and diatomaceous earth is particularly preferable in the present invention.

In FIG. 2, reference numeral 7 denotes an activated carbon layer, which is formed by molding fibrous activated carbon into a cylindrical shape and is capable of independently maintaining its shape. The activated carbon layer 7 is provided with an inner hole 71 through which the inorganic filter medium 1 can be inserted without a gap.

As shown in FIG. 3, connecting members 5A and 5B are fitted to both ends of the activated carbon layer 7 and the inorganic filter medium 1 to form an integrated structure of the activated carbon layer 7, the inorganic filter medium 1 and the connecting members 5A and 5B. Obtain the water purification cartridge 10. Reference numeral 6 is an elastic material for increasing the adhesion between the activated carbon layer 7 and the inorganic filter medium 1 and the connecting members 5A and 5B, respectively, whereby all the filtered water passes through the activated carbon layer 7 and the inorganic filter medium 1. . The inorganic filter medium 1 and the activated carbon layer 7 are connected to each other by connecting members 5A and 5B.
Water purification cartridge 10 because it is connected only by
When the connecting members 5A and 5B are removed from, the connection between the inorganic filter medium 1 and the activated carbon layer 7 can be released, and after the release, the activated carbon layer 7 can be separated from the inorganic filter medium 1.

FIG. 4 shows a water purifier 20 incorporating the water purification cartridge 10 shown in FIG. The outer shell of this water purifier 20 is configured by screwing a water purifier frame 21 and a water purifier frame 22. The water purification cartridge 10 has the mounting portion 4 inserted on the side of the water purifier frame 21 and the gap is sealed by an O-ring 8 provided in the mounting portion 4. The water purifier frame 22 is connected to a water tap (not shown). By opening the water tap, tap water containing contaminants S is supplied from the lower portion of the water purifier frame 22 as shown by an arrow Y1. . The tap water containing the contaminants S permeates the activated carbon layer 7, the filter aid layer 3 of the inorganic filter medium 1 and the support 2 from the area A outside the water purification cartridge 10 and flows into the area B inside the water purification cartridge 10. . At this time, residual chlorine and the like are first captured by the activated carbon layer 7. Further, the contaminants S in the tap water are captured by the filter aid layer 3, and the clear tap water not containing the contaminants S is the water purifier frame 2
Water is discharged from the upper part of 1 as shown by arrow Y2.

Since the activated carbon layer 7 is made of fibrous activated carbon, it is suitable for water having a high residual chlorine concentration such as summer water.

The water purification cartridge 10 can be removed simply by pulling it out of the water purification device 20, and again,
It can be attached to the water purifier 20 by inserting the attachment portion 4 on the side of the water purifier frame 21.

Since the mounting portion 4 is provided on the connecting member 5A, the mounting portion 4 does not block the flow of water, so that the water purifier 20 has a high filtering ability. Further, since the connecting member 5A also serves as the mounting portion 4 for the water purifier 20, the water purifier 20 can be space-saving.

An activated carbon protective layer (not shown) may be provided on the inner surface of the activated carbon layer 7. This activated carbon protective layer is an activated carbon layer 7
Although a non-woven fabric, a woven fabric, a wire mesh, etc. are adhered to the inner surface of the above, the non-woven fabric is preferable in the present invention. With the structure having such an activated carbon protective layer, the activated carbon layer 7
Even if the method for producing the water purification cartridge 10 by inserting the inorganic filter medium 1 into the inner hole 71 of No. 1 is used, the activated carbon layer 7 is less likely to be damaged when the inorganic filter medium 1 is inserted. Activated carbon layer 7
By disposing the activated carbon protective layer on the outer surface of, the collapse of the activated carbon layer 7 can be prevented. In addition, by setting the color of the activated carbon protective layer to be white, it becomes a standard for knowing the usage status of the water purification cartridge 10. This is because it is possible to visually confirm the process in which the activated carbon protective layer discolors to reddish brown due to the use of the water purification cartridge 10 due to a component such as iron rust which is a part of the contaminant S contained in the tap water. .

During filtration, the contaminants S in the tap water are filtered by the filter aid layer 3 due to the unique particle shape of the filter aid of the filter aid layer 3 and the high pore volume and thickness obtained by the fine pores.
Since it penetrates and is captured even inside, the clogging is suppressed, and the filtration area can be reduced to about 1/20 with the same filtration performance as in the case where the particles are captured only on the surface of the inorganic filter medium 1. Therefore, the water purifier 20 can be downsized.

Further, at the time of filtration, water pressure is applied to the filter aid layer 3 in the flow direction from the region A to the region B in FIG. 4, but the filter aid layer 3 is a support made of a water-permeable ceramic having high strength. Since it is supported by the body 2, the filter aid layer 3 does not collapse due to water pressure.

Further, even when the water supply plug is closed and the supply of tap water is stopped, the filter aid layer 3 is solidified by firing and therefore does not peel off from the support 2 made of permeable ceramics.

Moreover, the inorganic filter medium 1 is made of SiO ₂ , Al.
Because it is composed of inorganic minerals such as ₂ O ₃
It has excellent heat resistance and can purify hot water at 50 ° C or higher for a long period of time.

Since the activated carbon layer 7 is arranged on the outer periphery of the filter aid layer 3 of the inorganic filter medium 1, the effect of preventing the filter aid layer from peeling off when water supply is stopped is also improved.

In the present invention, if the firing temperature for solidifying the filter aid is too low below 800 ° C., the filter aid cannot be sufficiently solidified, and this temperature is too high.
If it exceeds 240 ° C., the filter aid is melted, impairing the fine pores and unique particle shape of the filter aid, and the filtration performance is deteriorated. Therefore, the firing temperature is preferably 800 to 1240 ° C. This firing temperature is especially 1000-1200 ° C.
Is preferred.

In order to sufficiently enhance the filtration performance of the inorganic filter medium 1, the filter aid used for forming the filter aid layer 3 has a pore volume of 0.5 cc / g or more, particularly 1 cc / g or more. The volume of pores of the water-permeable ceramics of the support 2 is preferably 3 times or more.

If the pore volume of the water-permeable ceramics of the support 2 is too high, the strength will be impaired, and if it is too low, the water resistance will increase, so 0.2 to 0.3 cc /
It is preferably about g.

The more preferable pore volume of the filter aid is 1.0 to
It is 3.0 cc / g.

Further, in order to obtain a sufficient trapping ability of the inorganic filter medium 1 inside the filter aid layer 3, the thickness of the filter aid layer 3 is preferably 1 mm or more, particularly 2 mm or more,
It is preferably at least one time the thickness of the support 2. If the filter aid layer 3 is excessively thick, the size of the inorganic filter medium 1 becomes large, so that it is preferably 6 mm or less.

The filter aid layer 3 may be formed as a single layer as shown in FIG. 1, or may be a composite layer in which two or more layers having different particle sizes and components are laminated.

FIG. 5 shows an activated carbon layer 7A in which granular activated carbon C is packed in a basket K. In FIG. 5, 71A is an inner hole. Since the activated carbon layer 7A is made of granular activated carbon C,
It is suitable for the time when the concentration of trihalomethane is high (autumn) and the local water.

As shown in FIG. 6, connecting members 5A and 5B are fitted to both ends of the activated carbon layer 7A and the inorganic filter medium 1 to form an integrated structure of the activated carbon layer 7A, the inorganic filter medium 1 and the connecting members 5A and 5B. Obtain the water purification cartridge 10A. Reference numeral 6 is an elastic material for enhancing the adhesion between the activated carbon layer 7A and the inorganic filter medium 1 and the connecting members 5A and 5B, respectively, whereby all the filtered water passes through the activated carbon layer 7A and the inorganic filter medium 1. . Since the inorganic filter medium 1 and the activated carbon layer 7A are connected only by the connecting members 5A and 5B, the connection between the inorganic filter medium 1 and the activated carbon layer 7A can be released by removing the connecting members 5A and 5B from the water purification cartridge 10A. After that, the activated carbon layer 7A can be separated from the inorganic filter medium 1.
The water purification cartridge 10A can be detachably incorporated into the water purifier 20 by using the mounting portion 4 (not shown). Water purification cartridge 10, water purification cartridge 10A
In addition, a water purification cartridge 10B (not shown) was obtained in which an ion exchange resin was mixed inside the activated carbon layer 7 of the water purification cartridge 10. Since the water purification cartridge 10B contains the ion exchange resin, it is particularly suitable for the period when the concentration of lead eluted due to the rise in the water temperature becomes high (summer season) or local water.
