(Field of Industrial Application) The present invention relates to a water purification device that purifies tap water or other water to a higher quality water when used for drinking. (Prior art) Traditionally, water purification devices use activated carbon to adsorb and remove impurities and substances that cause unpleasant odors in tap water.
Products that soften hard water using ion exchange resins, or purify water using ultrafiltration membranes and precision filtration membranes.
Furthermore, a combination of activated carbon and a membrane is also known. These devices have materials (activated carbon,
A cartridge containing an ion exchange resin, membrane, etc.) is installed inside, and the water introduced between the housing and the cartridge from the water supply port is guided into the cartridge from an opening provided at the top or bottom of the cartridge and treated with a material. (For example, Utility Model 60-46192
number, etc.). In such water purification devices, water quality deteriorates,
In other words, the cartridge must be replaced as soon as the material reaches the end of its life. In water purification devices that use membranes as materials, the end of the material's life can be easily detected by the fact that the membranes become clogged and the amount of water collected decreases. In a water purification device that combines a membrane and activated carbon or ion exchange resin, use an amount of activated carbon that is considered to have a lifespan sufficiently longer than the expected lifespan of the membrane. By replacing the activated carbon, water quality deterioration due to a decline in the performance of activated carbon was prevented. In addition, in water purification devices that use activated carbon, the drop in water sampling capacity due to clogging is negligible, so the time for replacement is determined based on the judgment of performance deterioration based on sensory factors such as taste, or on the basis of a preset period of use. The reality is that this is happening. (Problems to be solved by the invention) Conventional devices that combine membranes and activated carbon use more activated carbon than necessary, which inevitably increases costs. Furthermore, it is actually difficult to detect the deterioration of activated carbon visually. Furthermore, the method of determining when to replace a cartridge based on the period of use is usually to attach a label indicating the period of use or replacement period to the water purification device, and then replace the cartridge when the time comes, but it can take anywhere from a few months to a year. There was a risk that the label would become dirty or peel off during the period of use, making it unclear when to replace it. (Means for Solving the Problems) Therefore, the present invention aims to easily detect the lifespan of a conventional water purification device using activated carbon. The water purification device of the present invention is a water purification device containing activated carbon, and the water purification device is integrally provided with a transparent airtight container having small holes plugged with a hydrophobic porous member, and a liquid is contained in the container. This water purification device is characterized by: (Function) The device of the present invention can seal the container by appropriately selecting the diameter of the small hole provided in the wall of the container, the amount of liquid in the container, and the pore size and porosity of the hydrophobic porous member that closes the small hole. Since the evaporation period of the liquid contained in the container can be freely controlled, the display period can be set according to the lifespan of the activated carbon. (Example) Next, an example of the device of the present invention will be described with reference to the drawings. In the device of the present invention, a small hole 2 is provided in a transparent closed container 1, and the small hole is closed with a porous member 3. A liquid 4 is contained within the closed container 1. The closed container 1 is made of a transparent resin such as polypropylene, polycarbonate, polystyrene, or a slightly colored transparent resin. This container usually has a capacity of about 3 to 10 c.c., and in order to be integrated with the water purification device, various shapes shown in FIGS. 1 to 4 are used. The small holes 2 provided in the wall of the closed container 1 are usually 1 to 2.
It has a diameter of 3mm. This small hole is provided in the bottom wall of the closed container in FIGS. 1 and 4, and in the top wall in FIGS. 2 and 3. The hydrophobic porous member 3 that closes the small pores 2 is made of a hydrophobic resin such as polypropylene or tetrafluoroethylene, and has an average pore diameter of 0.1 to 0.5 μm and a porosity of 15 to 15.
It is a 60% porous sheet or molded body, and the small pores are closed with this member. Usually, the sheet-like body is adhesively fixed to a wall having small holes as shown in the drawings. The airtight container 1 is attached to a casing forming a water purification device. For example, in the case of the container shown in FIG. 1, the container is fitted and fixed into an opening provided at the bottom of the water purifier 5, as shown in FIG. Further, the containers shown in FIGS. 2 and 4 are attached to the side wall of the casing of the water purifier. Further, the container shown in FIG. 3 is installed upright on a mounting base provided at the bottom of the water purification device. The liquid 4 contained in the closed container 1 is a transparent liquid or a liquid slightly colored with dye or the like. Water is usually used as the liquid, but the water may also contain aromatics, deodorizers, disinfectants, etc. When storing a liquid in the sealed container 1, the liquid is poured into the container with one side wall open, and then the side wall is adhered to the open part, thereby producing a closed container containing the liquid. In the sealed container, liquid vapor that has passed through the porous member 3 diffuses out of the container through the small holes 2 and decreases over time. This reduction in liquid can be confirmed through the container 1. Therefore, by mounting the airtight container in a position directly facing the user of the water purification device, it is possible to check from the liquid level 4 in the airtight container each time the water purification device is used whether or not the activated carbon is within the replacement period. Next, Table 1 shows the results of examining the evaporation period using the closed container shown in FIG.

[Table] As shown in Table 1, by changing the amount of liquid, the diameter of the small pores, the thickness of the porous member, the pore size, and the porosity, the evaporation period of the liquid, that is, the display period of the activated carbon life, can be changed to one month. It can be set as appropriate for one year or more. This evaporation period is short at high temperatures and long at low temperatures, but the amount of off-odor components that activated carbon should adsorb is large at high temperatures and small at low temperatures, so the lifespan of activated carbon is short at high temperatures and short at low temperatures. It can be seen that the lifespan of activated carbon can be determined by the evaporation period of the liquid. (Effects of the invention) As described above, the water purification device of the present invention is an excellent water purification device that can prevent water quality deterioration in advance because the lifespan of the activated carbon stored in the water purification device can be checked in a simple manner.
