Description

  The present invention relates to a water purifier.

  It is said that water resources are one of the scarce resources in the global environment. Most of the water on Earth is seawater, with only about 2.5% fresh water. Since most of the fresh water is ice or glaciers in the polar regions, the amount of water available to humans is very limited. Therefore, securing water resources is an important concern for each country. On the other hand, even in countries where water resources are relatively abundant, if a natural disaster such as an earthquake or typhoon hits a disaster, the victims are immediately exposed to the risk of running out of drinking water and domestic water. become.

  Rivers, lakes, groundwater, etc. are typical examples of water that can be used by humans, but even if they can be used for domestic use, they are usually used in countries or regions where industry is thriving. It is difficult to use as a beverage. In addition, it is not easy for a country or region where the social infrastructure represented by electricity, gas, and water supply is not sufficient to secure the water consumed by residents in their daily lives.

  So far, a water treatment device using a semipermeable membrane unit for treating raw water (seawater, river water, groundwater, etc.) to obtain fresh water has been disclosed (for example, Utility Model Registration Document 1).

International Publication WO2013 / 125373

  As mentioned above, even in countries and regions that have water resources that are considered to exist naturally in everyday life, once a natural disaster occurs, Depletion is a real problem. Many of the desalination technologies disclosed so far can be realized in an environment where a social infrastructure such as electricity or gas can be used, or can be achieved on a relatively large scale.

  On the other hand, facilitating securing of drinking water and water for daily use (especially drinking water indispensable for life support) is not limited to dealing with the natural disasters described above. For example, when a social outage occurs, such as a local power outage, or when a family who loves the outdoors enjoys a barbecue or camp on the riverside in everyday life, it can be local or individual (for example, for each group) Creating technologies that can easily secure drinking water etc. for each family) is an important technical issue to be solved in modern society from the viewpoint of eliminating social anxiety or enriching human life. .

  The present invention solves at least a part of the problems described above. For example, in one aspect of the present invention, the fresh water can be easily purified mainly using solar cells, even in an environment where social infrastructure such as electricity or gas is not sufficient or not at all, It can greatly contribute to the realization of a water purifier with easy filter replacement.

  The inventor is not limited to those for leisure in everyday life, and in the unlikely event of natural disasters or power outages, drinking water and domestic water (especially essential for life support) I thought that satisfying the above-mentioned use would be easy to secure (drinking water), and worked hard on research and development. As a result, a water purifier that can be accommodated in a movable or portable storage box is created, making it possible to operate in the event of a disaster in which social infrastructure such as electricity or gas cannot be used. did. In addition, the inventors of the present invention have a different point of view from the above when a special situation such as a disaster (not only a natural disaster (so-called natural disaster) but also a human-caused disaster (so-called human disaster)) occurs. We have succeeded in creating a water purifier that can be used in a safer and more secure manner by paying careful attention to the impatience and anxiety of human beings. The present invention was created from the above viewpoint.

  Moreover, the storage box 10 in the water purifier 100 of this embodiment took water from the pump 40, the filter unit 20 provided with a plurality of filters (21, 22, 23) for purifying fresh water, and the water intake 42a. A water intake tube 42 for introducing fresh water into the pump 40, the control unit 30, and the storage battery 50 are accommodated.

  As shown in FIG. 3, the water purifier 100 of the present embodiment introduces fresh water taken using a water intake tube 42 into the first filter unit 21 via a pump 40 and a connection tube 44, and treats treated water. A control unit 30 is provided for controlling the pump 40 that discharges the treated water from the treated water tube 24 and discharges the concentrated water from the drainage tube 25. In addition, in addition to the above-mentioned control, after the light energy is converted into electric power by the solar cell 15a included in the housing lid portion 14 of the water purifier 100 of the present embodiment, the storage unit 50 of the control unit 30 of the present embodiment Control of storing the electric power and / or controlling the voltage of the electric power supplied from within the storage battery 50 is another aspect that can be adopted. Furthermore, a booster (not shown) for increasing the value of the voltage supplied from the storage battery 50 may be provided as necessary.

  More specifically, the filter unit 20 of the present embodiment includes, for example, a first filter unit 21 having a function of preliminary filtration and a first filter unit 21 as illustrated in FIGS. 1, 3, and 6. A second filter part 22 comprising at least activated carbon; a second filter part 22 following the second filter part; a third filter part 23 comprising at least a reverse osmosis membrane (hereinafter also referred to as “RO membrane” (Reverse Osmosis Membrane)); A treated water tube 24 that discharges treated water that has passed through the reverse osmosis membrane, a drainage tube 25 that drains concentrated water that has not permeated through the reverse osmosis membrane, a pump 40 and the first filter unit 21 are connected. The connecting tube 44 detachably attached to the pump 40 is integrated.

  Here, the first filter portion 21 into which fresh water is first introduced by the pump 40 has a function of preliminary filtration. Therefore, the 1st filter 21 can mainly play the role which removes fine solid matters, such as rust and dust, in the taken-in fresh water. As a result, it is possible to reduce the burden on the second filter unit 22 and / or the third filter unit 23 described later or delay the deterioration time. As long as it has the above-mentioned function, the type of filter in the first filter portion 21 is not limited, but a typical filter type is a thread wound filter or a resin filter.

Therefore, the second filter 22 can mainly play a role of removing chlorine or a part of chemical substances in freshwater taken or removing a musty odor, an organic matter, or the like. As a result, it is possible to reduce the burden on the third filter unit 23 described later and improve the safety of the treated water that is finally discharged. As long as it has the above-mentioned function, the type of filter in the second filter unit 22 is not limited, but a typical filter type is a granular activated carbon filter or a fibrous activated carbon filter. In addition, as a modified example of the second filter portion 22, for example, a combination of the above-described two types of activated carbon filters or a combination of the above-described activated carbon filters and an ion exchange resin filter for measures against hard water may be employed. It is an aspect.

  In addition, the third filter unit 23 to which the water that has passed through the second filter unit 22 is sent includes at least a reverse osmosis membrane. Therefore, the third filter 23 can mainly play a role of removing viruses, bacteria, heavy metals, or many chemical substances in freshwater taken. As a result, the treated water that has passed through the third filter unit 23 can be used not only for domestic water but also for beverages. On the other hand, since the water that has not passed through the third filter unit 23 becomes water to be discharged as concentrated water, it is necessary for the user of the water purifier 100 to clarify the distinction between the concentrated water and the treated water. Will increase the accuracy of safety. As long as it has the above-mentioned function, the kind of filter in the 3rd filter part 23 is not limited. In addition, in this embodiment, in order to pass the 3rd filter part 23 as much as possible and to increase treated water (in other words, to prevent unnecessary drainage of water to be filtered), it is shown in FIG. As described above, it is a preferable aspect to interpose a drainage resistor (restrictor) 70 in a part of the drainage tube 25.

  In the present embodiment, treated water of about 200 to about 300 mL / min can be discharged by employing the first to third filter parts (21, 22, 23) described above.

  Moreover, in FIG.1, FIG.5 and FIG.6, the water purifier 100 of this embodiment is respectively employ | adopted 1st filter part 21, 2nd filter part 22, and 3rd filter part 23 one each. However, the number of the first to third filter parts (21, 22, 23) provided in the water purifier 100 is not limited to one. For example, as long as it can be accommodated in the movable or portable storage box 10, the number of the first to third filter parts (21, 22, 23) is two or more. This is a preferred embodiment from the standpoint of increasing In particular, the provision of two or more third filter parts 23 that will set the upper limit of the processing amount per unit time for precise processing is a point of view for greatly improving the purification capacity of fresh water, for disasters or during power outages From the standpoint that it is possible to realize the necessary amount of water as soon as possible.

  In addition, the control unit 30 of the present embodiment introduces the fresh water into the first filter unit 21 via the pump 40 and the connection tube 44, and processes it by the first to third filter units (21, 22, 23). The pump for discharging the treated water from the treated water tube and discharging the concentrated water from the drainage tube is controlled. Moreover, although not necessarily provided, in order to improve the convenience of the water purifier 100 of this embodiment, for example, the control unit 30 further receives an AC 100V input for receiving power supply from a power source other than the solar battery. It is another preferable aspect to include a multi-function port unit 90 such as an external power supply port (for example, a USB port or an IEEE 1394 port) for supplying power to a known electrical appliance such as a terminal or a portable terminal. It is.

  Moreover, the storage battery 50 of this embodiment is a well-known lithium ion battery, for example. The storage battery 50 passes through a terminal box 15b for extracting electricity generated by each cell of the solar battery 15a, an electric wire 15c, connectors 15d and 34 provided for facilitating wiring work or replacement work, and the control unit 30. Thus, the electric power generated by the solar cell 15a is stored. Further, the storage battery 50 supplies the stored power to the pump 40 and the control unit 30. In addition, even if it is a case where the storage battery 50 of this embodiment is not provided, water purification of the fresh water by the water purifier 100 is possible. On the other hand, from the viewpoint of mitigating or preventing the instability (for example, voltage instability) of power supplied from the solar cell 15a that is easily influenced by external factors (for example, weather or the direction of the solar cell 15a), a storage battery It is a preferable aspect to supply power stably using 50.

  Although not particularly necessary in the present embodiment, for example, the connector 34 is used so that the storage battery 50 can be fixed when the water purifier 100 is used and can be removed when the storage battery 50 is replaced. It is a preferable aspect that can be adopted that the control unit 30 is detachably mounted and is temporarily fixed so as to be detachable from the storage box 10 using the hook-and-loop fastener 52.

[Replacement of filter unit 20]
Moreover, typically, as shown in FIG.3 and FIG.6, the filter unit 20 of the water purifier 100 of this embodiment is arrange | positioned in the storage box 10 so that attachment and removal with the filter unit 20 is possible. Accordingly, for example, the filter unit can be replaced with a new filter unit for the purpose of solving the problem of filter clogging that may occur with the passage of processing time. Specifically, a valve 49 capable of interrupting the flow of fresh water taken, treated treated water, and / or concentrated water to be drained is provided near the end of the connection tube 44 on the pump 40 side. It has been. In the present embodiment, the valve 49 is manually opened and closed.

  In addition, when replacing the filter unit 20 in which a plurality of filters (21, 22, 23) and the like are integrated, the circulation of fresh water, treated water, and / or concentrated water is blocked using the valve 49. Thus, the filter unit 20 can be easily removed from the storage box 10 by pulling out the connecting tube 44 from the joint (the joint of the pump 40 (position A in FIG. 6) or the joint of the valve 49 (position B in FIG. 6)). Can be removed. As an example of the above-described joint, a commercially available joint having a stopper function can be employed.

  By the way, although the water purifier 100 of this embodiment is provided with the one valve 49, the number of the valves 49 is not limited to one. For example, another (another) valve 49 may be provided in the range of the flow path of the connecting tube 44. The provision of the other valve 49 can prevent the water remaining on the pump 40 side from leaking with high accuracy, and the other valve 49 leaks the water remaining on the connection tube 44 side. This is preferable from the viewpoint of preventing the problem with high accuracy. In addition, from the viewpoint of preventing water leakage with higher accuracy, it is preferable that the two valves 49 are provided at a distance close to each other (for example, 10 cm or less). However, from the viewpoint of suppressing an increase in manufacturing cost, the number of valves 49 is preferably one.

  Further, when the filter unit 20 according to the present embodiment is replaced, the tube clip 13 that is housed inside the housing lid 14 and can be detachably held temporarily before and after removing the filter unit 20 temporarily. The filter unit 20 can be removed from the storage box 10 by removing the treated water tube 24 and the drainage tube 25 from the tube clip 13.

  As described above, after the filter unit 20 of the water purifier 100 is detached from the storage box 10, a process of attaching another (for example, new) filter unit 20 to the storage box 10 is performed, whereby the purified water of the present embodiment. The vessel 100 can be made to speak. Therefore, the above-described process can be regarded as one process of the water purifier 100 manufacturing process. In other words, after the filter unit 20 of the water purifier 100 is detached from the storage box 10, a process of attaching another filter unit 20 to the storage box 10 is performed, thereby reusing the water purifier 100 of the present embodiment. It becomes possible to do. Therefore, the above-mentioned process can be grasped as one process of the reuse method of water purifier 100.

  In the present embodiment, providing the valve 49 is a very preferable aspect from the viewpoint of realizing simplification of the replacement work of the filter unit 20. In the present embodiment, the filter unit 20 including the treated water tube 24, the drainage tube 25, and the connection tube 44 in addition to the first to third filter portions (21, 22, 23) is detachable. It is worth noting that it is arranged in the storage box 10. In addition, since the position where the valve 49 is provided is easy to understand for those who are not used to handling the water purifier 100, for example, it is preferably near the end on the pump 40 side, but the position is not particularly limited.

[Various tubes]
Moreover, the water purifier 100 of this embodiment is provided with the several tube from which a function differs as above-mentioned. Therefore, when the user is not accustomed to handling the water purifier 100 or when a special situation (disaster or power outage) occurs, the possibility that the user uses each tube by mistake increases. Therefore, in another preferable aspect of the water purifier 100 of the present embodiment, a water intake tube 42 and a connection tube 44 for sending the fresh water to the first fresh water filter unit 21 and a process for discharging the treated water. The water tube 24 and the drainage tube 25 that drains the concentrated water are colored in different colors. As a result, even if the user is not accustomed to handling the water purifier 100 or an emergency such as a disaster or a power outage occurs, the user can easily and easily divide various tubes. Can be used separately. In particular, when an emergency such as a disaster or a power failure occurs, it may be a situation in which it is not possible to make a calm or correct judgment by scorching or panicking. Therefore, the water intake tube 42, the connection tube 44, and the treated water tube 24 It is a particularly preferable aspect that the drainage tubes 25 are colored in different colors.

  Specifically, the water intake tube 42 and the connection tube 44 are, for example, colorless and transparent or colorless and translucent, or colored achromatic (for example, white or light gray). In addition, colorless and transparent or colorless and translucent may depend on the transparency of the tube material itself. The material of the typical water intake tube 42 and connection tube 44 is ABS resin, polyvinyl chloride (PVC), or medium density polyethylene (MDPE).

  Further, the treated water tube 24 is mainly colored in a cold color, for example. The cold color is a color that can be used as a color that suppresses excitement or shows a cleanliness, and is therefore more suitable as a color that represents treated water that can also be used for beverages. The treated water tube 24 of the present embodiment is colored in one color selected from the group of blue and green. From a similar viewpoint, it can be said that a neutral color (for example, green (including light green)) that can be used as a color indicating comfort or calmness is more suitable as a color representing treated water.

  On the other hand, the drainage tube 25 for draining the concentrated water is mainly colored in a warm color, for example. The warm color is a color that can be used as a color that can increase excitement or tension, or can exhibit a function as a warning color, and thus can be said to be more suitable as a color that represents concentrated water instead of treated water. . The drainage tube 25 of this embodiment is colored in one color selected from the group of red, orange, purple, black, and yellow, or the red, orange, purple, Two kinds of colors selected from black and the yellow group are colored in a striped pattern. In addition, from the viewpoint of making the user visually recognize more clearly, it is preferable that the two types of colors are colored in a stripe shape as described above.

[Arrangement in storage box 10]
Moreover, in other suitable one aspect | mode of the water purifier 100 of this embodiment, as shown in FIG. 1, the control part 30 is arrange | positioned in the storage box 10 near the handle 18, and the side far from the handle 18 is provided.

Therefore, the filter unit 220 of this embodiment includes the filter housing portion 80 that houses a part of each of the first to third filter portions (21, 22, 23) and the tubes (44, 24, 25). It is composed of

  In the present embodiment, since the entire surface of the filter housing portion 80 is opaque or translucent, the user of the water purifier 200 is usually inside the filter housing portion 80, that is, the first filter portion 21 and the second filter portion. 22, the third filter part 23, and the connection part of each filter part and the tube 24 for treated water etc. cannot be visually recognized clearly.

  Here, in particular, when used for disasters or power outages, when such an emergency occurs, the user may be in a situation where he / she is impatient or irritated and cannot make a calm or correct judgment. Therefore, for example, when a special situation such as a disaster occurs, the filter unit 220 is difficult to visually recognize or difficult to clearly see because of the complicated structure of the different filter parts for water purification. Thus, a smoother exchange of the entire filter accommodating portion 80 that accommodates many of the connecting portions (21a, 21b, 22a, 22b, 23a, 23b, 23c) can be realized. Further, even for those who are unfamiliar with the handling of the water purifier 200, it is difficult to visually recognize the complicated structure of each filter part for purifying water or to make it difficult to see clearly, the filter housing part 80 and the filter unit 220. This can contribute to the realization of a smoother exchange. Therefore, it is a preferable aspect to include the filter housing portion 80 of the present embodiment. From another point of view, the interior of the storage box 10 can be improved by adopting the filter storage portion 80 whose entire surface is opaque or translucent so that a complicated structure is difficult to see or clearly visible. It can be an element that can effectively improve the design of the storage box 10.

  By the way, the material of the filter housing portion 80 of the present embodiment has a mechanical or physical strength capable of realizing the replacement operation described later, and is opaque or difficult to visually recognize the inside of the filter housing portion 80. There is no limitation as long as it is a translucent material. A typical material of the filter housing portion 80 is polypropylene (PP) or polycarbonate (PC).

  Further, in the present embodiment, the hook-and-loop fastener 82 is provided so that the filter housing portion 80 can be fixed when the water purifier 200 is used and can be removed when the filter housing portion 80 is replaced. ing. As shown in FIG. 13, when the hook-and-loop fastener 82 is removed, the filter housing portion 80 and the filter unit 220 that are released from temporary fixing to the housing box 10 enable smooth replacement of the filter unit 220.

  As described above, after the filter unit 220 including the filter storage unit 80 in the water purifier 200 is detached from the storage box 10, a process of attaching another (for example, new) filter unit 220 to the storage box 10 is performed. Thus, the water purifier 200 of the present embodiment can be produced, so to speak. Therefore, the above-mentioned process can be grasped as one process of the manufacturing process of water purifier 200. In other words, after the filter unit 220 of the water purifier 200 is detached from the storage box 10, a process of attaching another filter unit 220 to the storage box 10 is performed, thereby reusing the water purifier 200 of the present embodiment. It becomes possible to do. Therefore, the above-mentioned process can be grasped as one process of the reuse method of water purifier 200.
