Description

Cartridge holder and cartridge device

The present invention relates to a cartridge holder and a cartridge apparatus.
This application claims priority based on Japanese Patent Application No. 2014-129297 for which it applied to Japan on June 24, 2014, and uses the content here.

Conventionally, water purifiers for the purpose of removing impurities such as chlorine contained in tap water have been widely used. Known forms of water purifiers include the faucet direct connection type attached to the faucet faucet, the stationary type installed on the sink, or the undersink type (built-in type) installed in the storage cabinet under the sink. Yes.

As such a water purifier, in particular, in the case of a water purifier used at home, an under-sink type water purifier has attracted attention because it does not impair the beauty around the sink. In recent years, it has become the mainstream to install drawers in the lower storage cabinet space of the system kitchen, so the undersink type water purifier is not a traditional back-floor platform but a small space in the storage cabinet. Also, it tends to be disposed in a dead space in the undersink, such as between the upper and lower sides of the drawer or the back of the drawer.

As a water purifier disposed in a dead space in an undersink, for example, in Patent Document 1, an apparatus main body for water treatment of raw tap water, and the apparatus main body outside a rear portion of a drawer in a cabinet space below a sink of a sink There has been proposed a water treatment device comprising a mounting tool for detachably mounting the device.
Moreover, as what concerns an undersink type water purifier, patent document 2 is a bracket of the water purifier which hold | maintains a water purifier horizontally and front-back in a cabinet, Comprising: The holder which hold | maintains the said water purifier so that attachment or detachment is possible Part, a fixing part to the cabinet, and a hose hooking part that is provided in front of the front end surface of the water purifier held by the holder part and hooks and holds the hose removed from the water purifier. A water purifier bracket has been proposed.

JP 2007-291653 A JP 2007-154513 A

However, in the water treatment apparatus of Patent Document 1, since the electrolytic cell and the water purification cartridge are accommodated in the apparatus main body, the size of the apparatus main body is large. Therefore, when replacing the water purification cartridge or the like, a narrow cabinet space is required. Since it is necessary to insert the hand and pull out the water purification cartridge from the apparatus main body, it is difficult to say that the water purification cartridge can be easily replaced. In addition, since the hose connected to the water purification cartridge is also moved with the withdrawal of the drawer body, stress is applied to the connecting portion between the water purification cartridge and the hose. In particular, the joint of the water purification cartridge is thin and relatively weak compared to the coupler part of the hose that is connected by extrapolation to this, so the water purification cartridge (equipment main body) is frequently put in and out of the joint of the water purification cartridge. If a large load is applied, there is a risk of damage.

Moreover, in the bracket of the water purifier of patent document 2, since the fixing | fixed part is being fixed to the inner surface of a cabinet with a screw, a tool is needed for the installation and the change of an installation position etc. is troublesome, and it is versatile. There are difficulties.

It is a perspective view which shows the modification of a cartridge holder.

Hereinafter, a cartridge holder and a cartridge device according to an embodiment of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a diagram showing a usage example of an embodiment of a cartridge device according to the present invention. In FIG. 1, reference numeral 1 denotes a cartridge device, and this cartridge device 1 is connected to a faucet 3 installed on a kitchen sink 2 via a pipe (not shown) and a hose 4.
That is, the cartridge device 1 is an undersink type (built-in type) water purifier.

In the usage example shown in FIG. 1, the cabinet under the kitchen is a drawer type that can slide in the front-rear direction, and the cartridge device 1 is attached to the side plate 5 on the back side of the lowermost drawer. In the example shown by the solid line in FIG. 1, the cartridge device 1 is accommodated and arranged inside the side plate 5, that is, inside the drawer. Further, as shown by a two-dot chain line in FIG. 1, it can be arranged outside the side plate 5, that is, on the back side (outside) of the drawer. In FIG. 1, the cartridge device 1 is attached to the back side inside the lowermost drawer, but it may be attached to the side surface inside the drawer.

As shown in FIG. 2, which is a schematic configuration diagram of the cartridge device 1, the cartridge device 1 includes a water purifier cartridge 10 and a cartridge holder 40.
As shown in FIG. 3, which is a cross-sectional view showing the overall configuration of the water purifier cartridge 10, the water (raw water source water) is filtered and purified by the filter medium 12 accommodated in the container body 11, and the purified water is shown in FIG. It discharges to the shown faucet 3 side.

That is, the water purifier cartridge 10 includes a container body 11 and a filter medium 12 accommodated in the container body 11.
The container main body 11 includes a bottomed cylindrical filter medium container 13 and a lid portion 14 attached to the opening side of the filter medium container 13.

The lid portion 14 is a substantially disk-like one that covers the opening of the filter medium container 13 and is formed of a hard resin, and its outer peripheral end is ultrasonic welded, vibration welded, or the like to the open side peripheral end of the filter medium container 13. It is fixed with. The lid portion 14 is formed with a water inlet joint 15 (water inlet joint) and a water outlet joint 16 (water outlet joint) on the outer surface side thereof. The joint of the present embodiment is configured to be able to connect a water pipe. Specifically, in the present embodiment, the water distribution pipe includes a hose 4 and a coupler that is connected to the end portion thereof and can be coupled to the joint. As shown in FIG. 1 and FIG. 2, the water inlet joint 15 is a tubular member configured to be liquid-tightly connected to an IN hose 4 having a water inlet coupler 17 connected to an end thereof. The water discharge joint 16 is a tubular member configured to be liquid-tightly connected to the OUT hose 4 to which the water discharge coupler 18 is connected.

As shown in FIG. 2, the water intake coupler 17 and the water discharge coupler 18 have an operation tube 20 that is externally inserted into the inner tube 19 so as to be capable of moving forward and backward. The large diameter portion 20 a of the operation tube 20 is advanced and retracted. Thus, the inner pipe 19 is externally inserted into the water inlet joint 15 and the water outlet joint 16 shown in FIG. 3, and the inner pipe 19 can be engaged with and disengaged from the large-diameter portion 15 a (16 a) of the water inlet joint 15 and the water outlet joint 16. It has a known configuration that is stopped. These water coupler 17 and water coupler 18 are sufficiently large in diameter compared with the water joint 15 and water joint 16, and are formed with a relatively high strength by a hard resin. The strength is higher than that of the water inlet joint 15 and the water outlet joint 16.

The water inlet coupler 17 and the water outlet coupler 18 have an inner pipe 19 exposed behind the large-diameter portion 20a in order to retract the operation pipe 20 when the operation pipe 20 is not operated, that is, in a steady state. The exposed inner tube 19 portion has a smaller diameter than the front large-diameter portion 20a and a smaller diameter than the hose 4 side of the coupler 17 (18), thereby forming an annular groove portion. In other words, the water inlet coupler 17 and the water outlet coupler 18 are formed with a groove formed by exposing the inner pipe 19 behind the large diameter portion 20a of the operation pipe 20.

The water inlet joint 15 and the water outlet joint 16 are arranged symmetrically across the central axis of the container body 11 as shown in FIGS. Moreover, it arrange | positions at the center side, without arrange | positioning at the peripheral side of the cover part 14. FIG. As a result, the water inlet joint 15 and the water outlet joint 16 are formed to have the same distance from the side peripheral surface of the container body 11.

The internal hole of the water inlet joint 15 communicates with the first water passage 21 formed between the filter medium container 13 and the filter medium 12 accommodated in the filter medium container 13, that is, outside the filter medium 12. Moreover, the internal hole of the water discharge joint 16 is connected to the end part side of the hollow fiber membrane mentioned later, ie, the opening side.

Here, the total length of the container body 11, that is, the length L from the tip of the water inlet joint 15 or the water outlet joint 16 to the bottom surface of the filter medium container 13 is, for example, about 220 mm to 300 mm, preferably about 250 mm to 280 mm. . When the length is 300 mm or more, the handleability is impaired or the installation location is limited. On the other hand, if the length is shorter than 220 mm, the required amount of filter medium cannot be filled, the filtration capacity is lowered, and the practicality is lowered. Further, the outer diameter of the container body 11 has a maximum diameter (d) of about 70 to 90 mm, preferably about 75 to 80 mm in the filter medium container 13. When the maximum diameter exceeds 90 mm, the handleability is impaired, or the installation in a narrow space becomes difficult, the installation location is limited, and the versatility is lowered. On the other hand, if the maximum diameter is 70 mm or less, the required amount of filter medium cannot be filled, the filtration capacity is lowered, and the practicality is lowered. Therefore, the ratio (L / d) between the length (L) of the container body 11 and the maximum diameter (d) of the container body 11 is, for example, between 2 and 5, preferably about 2.4 to 4.3. The water purifier cartridge 10 has a sufficiently slim structure. In addition, it is preferable that ratio of the length (L) of the whole water purifier cartridge 10 and the largest diameter is in the above-mentioned range. Therefore, as shown in FIG. 1, the water purifier cartridge 10 can be easily arranged in a narrow space in the undersink, such as the inside of the lowermost drawer or the back side thereof.

The filter medium 12 includes a molded activated carbon 22 and a hollow fiber membrane 23, which are arranged along the central axis direction of the filter medium container 13. The molded activated carbon 22 is disposed on the bottom side of the filter medium container 13, and the hollow fiber membrane 23 is disposed on the lid 14 side. The filter medium 12 composed of the molded activated carbon 22 and the hollow fiber membrane 23 is disposed with a slight gap between the filter medium 12 and the outer filter medium container 13. That is, a gap is formed over the entire circumference of the filter medium 12.

An annular gap between the filter medium 12 and the filter medium container 13 that is continuous in the circumferential direction of the filter medium container 13 is the first water passage 21 described above. As described above, the first water passage 21 communicates with the internal hole of the water inlet joint 15 so that the water flowing in through the water inlet joint 15 flows. The first water passage 21 has a cross-sectional area of the flow path, that is, an opening area of a cross section perpendicular to the central axis, of 0.3 cm ^{2 to} 8 cm ² , preferably 1.0 cm ^{2 to} 5.5 cm ² It has become. If it is smaller than 0.3 cm ² , the pressure loss becomes high and a sufficient amount of water cannot be secured. Moreover, when larger than 8 cm < ² >, the amount of filter media will decrease and sufficient filtration performance cannot be obtained.

Here, the hollow fiber membrane case 23 is accommodated in a cylindrical hollow fiber membrane case 24, and therefore the side surface side thereof is closed, so that the hollow fiber membrane case does not directly communicate with the first water passage 21. 24. Therefore, the water that flows into the first water passage 21 through the water inlet joint 15 flows to the bottom side of the filter medium container 13, that is, to the molded activated carbon 22 side, without directly flowing to the hollow fiber membrane 23 side. Yes.

As the hollow fiber membrane 23, those usually used as filter media for water purifier cartridges can be used. Specifically, for example, cellulose, polyolefin (polyethylene, polypropylene), polyvinyl alcohol, ethylene / vinyl alcohol copolymer, polyether, polymethyl methacrylate (PMMA), polysulfone, polyacrylonitrile, poly A material made of various materials such as tetrafluoroethylene (Teflon (registered trademark)), polycarbonate, polyester, polyamide, or aromatic polyamide can be used. Of these, polyolefin-based or polysulfone-based ones are used in view of handling properties and processing characteristics.

The hollow fiber membrane 23 is a hollow fiber membrane bundled in a loop shape, the lid portion 14 side (exit side) being bonded and fixed with urethane resin, epoxy resin or the like, and the end portion opened so as not to be blocked by the resin Thus, the hollow fiber membrane case 24 is accommodated and fixed. The hollow fiber membrane 23 having such a configuration has an effective membrane area, that is, an effective filtration area, of 0.4 m ² or more and 0.8 m ² or less, for example, about 0.64 m ² . The effective membrane area is calculated by the product of the outer diameter of the hollow fiber membrane and the length and number of portions not covered with the resin.

Further, on the lid portion 14 side of the hollow fiber membrane case 24, a lid portion side cap 25 is attached to the opening. The lid-side cap 25 is formed with a cylindrical connecting tube 26 that is inserted into the inner hole of the water discharge joint 16 and communicates with the water discharge joint 16. Thus, the purified water filtered by the hollow fiber membrane 23 is guided to the water discharge joint 16 through the connecting tube 26 and sent to the faucet side.

It should be noted that an O-ring is interposed between the connecting tube 26 of the lid portion side cap 25 and the internal hole of the water discharge joint 16, thereby ensuring good water tightness. The inner diameter of the inner hole of the water discharge joint 16 on the filter medium container 13 side is formed larger than the inner diameter of the inner hole of the water inlet joint 15 on the filter medium container 13 side. Thereby, even if it tries to connect the water-injection joint 15 to the connection pipe | tube 26 accidentally at the time of an assembly, since these cannot be fitted, it is prevented from being assembled accidentally. Furthermore, because of this structure, the central axis of the filter medium 12 and the central axis of the lid portion 14 are arranged on a concentric axis, so an annular gap between the filter medium 12 and the filter medium container 13 (first water passage 21). However, it becomes uniform over the entire circumference, and the flow of water flowing in from the water inlet joint 15 can be evenly dispersed.

Inside the lid portion 14, ribs (not shown) for increasing the strength are provided radially. Since the protruding portion 27 is formed on the lid portion side cap 25 and this protruding portion 27 is formed so as to be fitted into the fitting concave portion 14a of the lid portion 14, this rib increases the pressure resistance of the lid portion 14. Can do. However, when the protruding portion and the fitting recess are provided in reverse, that is, when the fitting concave portion is provided in the lid-side cap 25 and the protruding portion is provided in the lid portion 14, the rib is the protruding portion (the center of the lid portion 14). ) Must be lowered toward. Therefore, the strength of the lid part 14 is lowered, which is not preferable.

Also, the lid portion side cap 25 is formed with a protruding portion 27 at the center (on the center axis). The protruding portion 27 is formed and arranged so as to be fitted into a fitting recess 14 a formed at the center of the lid portion 14. In the hollow fiber membrane case 24 in which the hollow fiber membrane 23 is accommodated in such a configuration, the protruding portion 27 of the lid portion side cap 25 attached thereto is fitted into the fitting concave portion 14 a of the lid portion 14. As a result, rattling is prevented. In addition, when the water purifier cartridge 10 is placed horizontally, the filter medium 12 is prevented from being biased in the filter medium container 13.

The molded activated carbon 22 is formed in a cylindrical shape, the end on the bottom side of the filter medium container 13 is bonded to the bottom side cap 28 by hot melt, and the end on the hollow fiber membrane 23 side is a partition plate 29 with holes. And are bonded by hot melt. That is, the molded activated carbon 22 is sandwiched between the bottom side cap 28 and the partition plate 29, and water is configured to flow radially inward between the bottom side cap 28 and the partition plate 29. Has been. The inner hole 22 a of the molded activated carbon 22 serves as a second water passage, and is arranged in communication with a cylindrical water passage 29 a formed at the center of the partition plate 29. That is, the water passage portion 29 a is inserted into the inner hole 22 a of the molded activated carbon 22. In addition, three protrusions are provided on the outer periphery of the bottom side cap 28. By this protrusion, a gap is formed between the bottom side cap 28 and the inner side surface of the filter medium container 13, and water flows to the bottom side of the filter medium container 13. The protrusion is preferably 1.0 mm to 2.0 mm. If it is smaller than 1.0 mm, it is difficult for water to flow. Further, when the water purifier cartridge 10 is placed horizontally, the first water passage 21 is biased toward the bottom surface when the water purifier cartridge 10 is placed horizontally, and water flows between the bottom side cap 28 and the bottom of the filter medium container 13. It becomes difficult. When it is larger than 2.0 mm, the amount of the filter medium decreases, and sufficient filtration performance cannot be obtained. A cylindrical portion 28 a is also formed at the center of the bottom side cap 28, and this cylindrical portion 28 a is inserted into the internal hole 22 a of the molded activated carbon 22. In addition, a groove is dug in the bottom side cap 15 and the partition plate 16, and this groove improves adhesion to hot melt.

In the case of the water purification cartridge 10 in which a water inlet and a water outlet are provided at one end as in this embodiment, water tends to stay between the bottom side cap 28 and the bottom of the filter medium container 13. In particular, since the end on the bottom side of the molded activated carbon 22 is bonded to the bottom side cap 28, water does not flow from the end surface on the bottom side of the molded activated carbon 22 toward the internal hole 22a. Therefore, water may stay for a long time. Therefore, the outer diameter of the bottom side cap 28 is preferably set to be smaller by 0.5 mm to 1.0 mm than the inner diameter of the filter medium container 13 in contact therewith. By providing in this range, the amount of water at the bottom can be increased, so that retention of water can be prevented. If it is larger than 1.0 mm, the generated activated carbon 22 is not stable and the amount of filter media is reduced, which is not preferable. Moreover, when smaller than 0.5 mm, the clearance gap with the filter medium container 13 will become narrow, and the amount of water which flows into a bottom part cannot be increased.

As shown in FIG. 4, a plurality of ribs 13 b are radially formed on the bottom inner surface 13 a of the filter medium container 13 from the center of the bottom inner surface 13 a to the outer peripheral side. These ribs 13 b are formed in a linear shape that protrudes toward the bottom side cap 28, that is, in a protruding line. By providing these ribs 13b, it is possible to prevent the fitting between the connecting cylinder 26 and the inner hole of the water discharge joint 16 from being removed. Accordingly, it is possible to prevent the filter medium 12 from being detached from the lid portion 14. Moreover, the pressure resistance of the bottom part of the filter medium container 13 can be raised by providing the rib 13b. As in this embodiment, the water purification cartridge 10 is provided with a water inlet and a water outlet at one end, and the end surface of the molded activated carbon 22 is bonded with a cap. In some cases, water may stay for a long time. In order to improve the flow of water, the height of the ribs 13b is preferably 2 to 5 mm so that water does not accumulate at the bottom and preferably 3 to 4 mm. If it is larger than 5 mm, the gap between the bottom side cap 28 and the bottom inner surface 13a of the filter medium container 13 becomes small, so the flow of water becomes worse and accumulates. If it is smaller than 2 mm, the pressure resistance of the bottom of the filter medium container 13 cannot be increased.

The molded activated carbon 22 has a water-permeable nonwoven fabric (not shown) pasted on the outer peripheral surface thereof. As this nonwoven fabric, one having an appropriate opening is used so that coarse dust can be removed. The method for applying the nonwoven fabric to the molded activated carbon 22 is not particularly limited as long as it is a method that does not impair the opening of the nonwoven fabric and has no problems in strength, workability, etc. Is preferable because it is inexpensive and simple.

Further, a water collecting pipe 30 is provided on the inner surface on the inner hole side. The water collection pipe 30 substantially functions as a second water passage, collects water that has permeated through the molded activated carbon 22 and guides it to the water passage portion 29a side of the partition plate 29, and is provided on the inner hole 22a side. It consists of a water-permeable nonwoven fabric (not shown) that abuts on the inner surface of the glass and a cylindrical core material (not shown) provided on the inside thereof.

The core material is used to reinforce the molded activated carbon 22 in order to prevent the molded activated carbon 22 from being damaged as water flows through the molded activated carbon 22. As such a core material, any material can be used as long as it can maintain the shape of the molded activated carbon 22 at the time of water filtration. For example, a cylindrical resin provided with a large number of holes in a lattice shape, or a low-melting fiber Etc., which are heat-molded using a material such as a water-permeable pipe. As the non-woven fabric of the water collecting pipe 30, the same non-woven fabric stuck on the outer peripheral surface of the molded activated carbon 22 is used.

Here, the flow passage cross-sectional area of the water collecting pipe 30, that is, the opening area A1 of the transverse cross section orthogonal to the central axis is A1 / A2 = (1 /0.2) to (1 / 5.3), preferably (1 / 0.7) to (1 / 3.7). By forming the flow passage cross-sectional area A1 of the water collecting pipe 30 to such a size with respect to the flow passage cross-sectional area A2 of the first water passage 21, a sufficient water flow rate is secured in the entire water purifier cartridge 10. It has become so.

As described above, the partition plate 29 is attached to the end portion of the molded activated carbon 22 on the hollow fiber membrane 23 side, and is also attached to the hollow fiber membrane case 24. That is, the hollow fiber membrane case 24 containing the hollow fiber membrane 23 is attached so as to cover the opening on the molded activated carbon 22 side. Therefore, as described above, the water flow portion 29a formed at the center portion of the partition plate 29 is inserted into and communicated with the internal hole (second water flow passage) of the molded activated carbon 22, more specifically, the water collecting pipe 30. Thus, the inside of the water collecting pipe 30 (second water passage) and the inside of the hollow fiber membrane case 24 communicate with each other through the water passage portion 29a. That is, the water flowing in the water collecting pipe 30 flows into the hollow fiber membrane case 24 through the water passage portion 29a.

The water purifier cartridge 10 has a total length of the container body 11, that is, a length L from the tip of the water inlet joint 15 or the water outlet joint 16 to the bottom surface of the filter medium container 13 is about 220 mm to 300 mm. L) and the ratio (L / d) between the maximum diameter (d) of the container body 2 is 2.4 or more and 4.3 or less, so that the overall size is small and slim. Yes. In addition, since the water inlet joint 15 and the water outlet joint 16 are provided on one side in the length direction, an IN hose (a water inlet coupler) and an OUT hose (a water outlet coupler) are connected to the water inlet joint 15 and the water outlet joint 16, respectively. They can be connected together in the same direction.

Therefore, for example, the water purifier cartridge 10 is arranged in a narrow space in the undersink, specifically in a narrow space in the storage cabinet, between the top and bottom of the drawer, the back of the drawer, or in the bottom drawer, and the IN hose, OUT It can be used as a water purifier by connecting the hose to the faucet. At that time, the water purifier cartridge 10 can be used horizontally or vertically, and therefore can be arbitrarily arranged according to the form of the space as the installation place without being limited to the placement.
