Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a simple water purifier for purifying drinking water or the like, and more particularly, to a water purifier capable of visually checking the replacement time of a filter member.
[0002]
[Prior art]
Conventionally, this type of water purifier incorporates activated carbon or a hollow fiber membrane inside a casing, and supplies purified water by supplying tap water into the casing and filtering it with an internal filter.
When the predetermined flow rate is filtered, the filter is clogged and the filtration performance is lowered. Therefore, it is necessary to replace the filter with a new filter at the time when the flow rate is lowered.
This replacement time may be replaced after a predetermined period of time, but it is difficult to replace it at the optimal time due to the difference in the flow rate used. A water purifier has also been proposed in which a flow sensor is provided and the replacement time is confirmed by fluctuations in pressure and flow rate.
[0003]
[Problems to be solved by the invention]
However, the above-mentioned conventional water purifier needs to be provided with a pressure sensor or the like, which causes a complicated structure and increases costs, and the pressure sensor or the like indicates an incorrect replacement time due to fluctuations in the flow rate. On the other hand, there was a problem that the proper replacement time could not be confirmed.
The present invention has been developed in view of the conventional problems, and it is possible to reliably check the replacement time of a filter with a water purifier having a simple structure, and in addition, a water purifier excellent in environmental performance. The purpose is to provide.

The container 1 has a bottom wall 1a formed on the bottom wall 1a. A screw portion 1b is provided at the opening, and a cap 2 is screwed into the male screw portion 1b. The cap 2 has an inlet 3 for raw water and an outlet 4 for water purification. Inflow outlets 3 and 4 are provided with plugs 5 and 6 which are paired with sockets of quick joints, and one of the sockets (not shown) is connected to a water supply line and the other is connected to a purified water outflow path.
[0008]
A packaging material 7 made of a resin sheet is shrink-wrapped on the side surface of the transparent or translucent container 1.
On the packaging material 7, a morphological pattern portion 8 is printed by appropriately combining characters, figures, symbols, shapes, patterns, colors, and the like. In this example, a wave figure 9 with an appropriate color and a bubble-like circular part 10 in water are drawn, and this circular part 10 forms a viewing area 11 which is a part of a morphological pattern part. ing. In the case of this example, the wave figure and the bubble figure are combined to express the underwater and have a formally integrated structure. In this case, the packaging material 7 is removed from the container 1 to enable recycling, thereby improving the environmental performance .
[0009]
In the figure, reference numeral 12 denotes a filter member. A casing 12a of the filter member 12 is provided with prefilters 14a and 14b such as non-woven fabric formed in a cylindrical shape on a side surface with a bottom portion closed by a cap portion 13. A fibrous activated carbon layer 14c is interposed between the intermediate layers of the filters 14a and 14b, and a granular activated carbon 15 is incorporated in the casing 12a and a hollow fiber membrane 16 communicating with the water purification outlet 4 is provided in the center.
In the figure, 17a and 17b are sealing members, 18 is an outer cylinder, and 19 is a potting portion.
[0010]
Next, the operation of the above embodiment will be described.
Drinking water or the like from the water supply is injected from the raw water inlet 3 into the container 1, and the raw water is filtered as a side flow from the side surface of the casing 12a of the filter member 12, and the prefilters 14a and 14b and the fibrous activated carbon layer of the casing 12a. Prefiltered through 14c.
[0011]
Next, the chlorine component is removed by the granular activated carbon 15, and the fine particles such as the particulate matter are reliably filtered by the hollow fiber membrane 16 to become purified water, which flows out from the purified water outlet 4.
As described above, when the filtration by the filter member 12 is continued for a predetermined period, a clogged state is generated, and fine particles and dirt adhere to the outer peripheral surface of the prefilter 14a located on the outermost side surface of the casing 12a. For example, the white pre-filter 14a turns brown.
Since the discolored state of the pre-filter 14a can be viewed from the viewing area 11, the replacement time can be easily confirmed by a simple structure based on the discolored state, and the filter can be replaced with a new filter member at an appropriate time. By doing so, it can be purified continuously.
In this case, the filter member 12 can be filtered with five layers of three layers of pre-filters 14a, 14b, 14c, granular activated carbon 15 and hollow fiber membrane 16, so it is always a long time with a water purifier that maintains filtration performance. It can be used throughout.
[0012]
Further, the raw water is filtered as a side flow from the side surface of the casing 12a of the filter member 12, and the prefilter 14a can be easily obtained via the visual region 11 provided in the packaging material 7 shrink-wrapped on the side surface of the container 1. Therefore, it is possible to check the replacement time of the filter member 12 in a normal water purifier installation state without lifting or tilting the water purifier.
In this case , the discoloration state of the pre-filter 14a can be visually recognized in a multifaceted manner by dispersing a plurality of viewing areas 11, and further, left and right and up and down positions thereof, and is affected by local changes in the filtration state. The replacement time of the filter member 12 can be confirmed without any problem.
[0013]
【The invention's effect】
Therefore, according to the present invention, the outer surface of the container is provided with a morphological pattern portion by appropriately combining characters / graphics / symbols or shapes, patterns, colors, etc., and a filter member is formed on a part of the morphological pattern portion. Since it is a water purifier configured to provide a visible or transparent viewing area that can be visually observed, and to integrate the form of the viewing area in combination with the morphological pattern portion, it exhibits an aesthetic appearance and has a decorative value. In addition to having, it is possible to visually recognize the internal filter member from the viewing area of the pattern portion, so the discoloration state of the outer surface of the filter member can be easily checked, its replacement time can be easily confirmed, even by long-term use, The water purifier can be used with the filtration performance always maintained.
[0014]
Moreover, since the effect can be exhibited with a simple structure as compared with the conventional product, it does not cause an increase in cost and is excellent in economic efficiency.
In particular, it is possible to avoid pollution problems when the water purifier is made into a recycled product by shrink-wrapping the shape pattern portion and removing it from the container itself.
[0015]
Furthermore, according to the present invention, the filter member includes a casing that closes the bottom and filters from the side, a granular activated carbon in the casing, and a hollow fiber membrane that communicates with the water purification outlet at the central portion. Since the pre-filter made of nonwoven fabric and the fibrous activated carbon layer are interposed in the pre-filter, not only chlorine substances but also trihalomethane, environmental hormones or other substances can be filtered, and the performance as a water purifier can be remarkably enhanced.
Moreover, the conventional water purifier cannot confirm the whole filtration state, even if it can visually recognize from the outside, when a pre filter exists in the upper surface and lower surface of a container. In contrast, the present invention has a structure in which the raw water enters the casing from the side surface of the filter member, so that the internal filter member can be easily visually recognized from the viewing area of the outer surface of the container described above, and the normal installation state Can check the filtration state of the filter.
