Description

Water purifier

The present invention relates to a water purifier.

In general households, for example, pot-type water purifiers are used to purify raw water such as tap water and use it as drinking water. This pot-type water purifier includes a main body container having a raw water chamber located on the upper side and a water purification chamber located on the lower side, and a water purification cartridge interposed between the raw water chamber and the water purification chamber. . And purified water is produced | generated when raw | natural water passes a water purification cartridge, and the produced | generated purified water is stored in the water purification chamber.

By the way, in this pot-type water purifier, since the main body container is usually formed in a size that can be stored in a refrigerator or the like, the amount of purified water that can be generated at one time is limited. Therefore, the amount of purified water is earned by repeated use. However, particularly in summer, the amount of purified water used as drinking water increases, so the ability to purify raw water in a short time has been required.

Therefore, for example, in Patent Document 1, a dome-shaped cloth insert is disposed between a filter cup and a lid of a water purification cartridge, and the cloth insert is provided in contact with a purifying agent such as activated carbon, thereby providing a sieve-shaped inlet. The thing which interrupted | blocked the surface tension of the water led from this and suppressed the water flow resistance by the back pressure of air is disclosed.

Japanese Patent Laid-Open No. 10-76253

However, in the above prior art, although water resistance can be reduced in the initial stage of use, since the flow of water concentrates on the contact portion of the cloth insert, the cleaning agent that has been in contact is gradually pushed away and does not come into contact. In the latter period, the resistance to water flow increased and there was a possibility that the generation of purified water could not be performed smoothly.

Therefore, an object of the present invention is to obtain a water purifier capable of generating purified water stably and smoothly over the initial period of use and the latter stage of use.

In the present invention, a main body container in which a raw water chamber for storing raw water and a water purification chamber for storing purified water are formed, a bottom wall portion of a partition wall that partitions the raw water chamber and the water purification chamber, and the raw water chamber A cartridge housing portion having an opening communicating with the water purification chamber and a purification chamber filled with a purification agent are formed, and a filter is disposed so as to cover the purification chamber. A water purification cartridge having a water inlet at a higher position, wherein the purified water is generated with the bottom wall portion of the main body container facing down, and the water purification cartridge is moved to the cartridge housing portion. In the mounted usage state, the filter is arranged to be inclined with respect to the vertical axis of the main body container.

According to the present invention, the filter of the water purification cartridge is disposed so as to be inclined with respect to the vertical axis of the main body container in a use state where the water purification cartridge is mounted in the cartridge housing portion. Therefore, the flow path is secured by bringing the purifier into contact with the lower side of the inclined filter, and the air collected on the higher side of the filter can be easily discharged to the outside by the passed water. It becomes possible to generate purified water stably and smoothly.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that similar components are included in the following embodiments. Therefore, in the following, common reference numerals are given to those similar components, and redundant description is omitted.

[First Embodiment]
Drawing 1 and Drawing 2 are figures showing a 1st embodiment of a water purifier concerning the present invention.

As shown in FIG. 1, the water purifier 1 of this embodiment is configured as a pot-type water purifier, and has a substantially bottomed cylindrical main body container 2 and an inner container ( (Partition wall) 3 and a water purification cartridge 10 are provided. And by arranging the inner container 3 in the cylinder of the main body container 2 so that the top wall 8 of the main body container 2 is desired, the inner side of the inner container 3 is divided into the raw water chamber 4 and the outer side is divided into the water purification chamber 5. Yes.

The bottom wall portion 3a of the inner container 3 is formed with a substantially cylindrical recess (cartridge housing portion) 3b having an opening 3c that communicates the raw water chamber 4 and the water purification chamber 5, and the recess 3b A substantially cylindrical water purification cartridge 10 is inserted and fitted from the top to the back. In this state, the lower part 10 b of the water purification cartridge 10 is exposed from the opening 3 c and faces the water purification chamber 5. Then, while pouring raw water into the raw water chamber 4 with the bottom wall 2 a of the main body container 2 facing down, purified water is generated by passing the raw water through the purified water cartridge 10, and the generated purified water is supplied to the purified water chamber 5. Stored.

The top wall 8 in which the water supply port 8a is formed is disposed above the raw water chamber 4. The water supply port 8a is closed so as to be openable and closable by a top-opening type lid 9 that is rotatably attached to the top wall portion 8 via a hinge 9a. The raw water is supplied into the raw water chamber 4 through the water supply port 8a with the lid 9 opened upward.

Further, a passage 7 extending upward from the water purification chamber 5 is formed between the side wall 3e of the inner container 3 and the main body container 2, and the main body container 2 or the top wall 8 has the passage 7 A water inlet 7a is formed at a position to be the upper end. In this embodiment, the main body container 2 is tilted so that the water injection port 7a is located downward (in FIG. 1, by tilting the main body container 2 in the clockwise direction), the purified water stored in the water purification chamber 5 is collected. The water is discharged from the water inlet 7a through the passage 7. In this embodiment, the water inlet 7a is closed so as to be openable and closable by a top-opening lid 20 that is rotatably supported by the main body container 2 or the top wall 8. In this case, when the main body container 2 is tilted, the lid 20 can be rotated by its own weight, dynamic pressure of water, or the like to open the water inlet 7a.

As shown in FIG. 2, the water purification cartridge 10 has a bottomed cylindrical case 14 in which a top surface is opened and a purification chamber S2 filled with a purification agent 12 is formed, and a filter that covers the purification chamber S2. 16 and a lid 15 coupled so as to cover the opening 14e of the case 14 and having the water inlet 11 formed at a position higher than the filter 16.

The lid 15 has a cup 17 in which the inner cylinder 17d extends downward substantially along the central axis Ax of the water purification cartridge 10 from the top wall 17b of the outer cylinder 17a, and a protrusion 18a inserted through the lower end of the inner cylinder 17d. The cap 18 which forms additive storage chamber S1 is provided inside. The additive storage chamber S1 is configured to store an additive (not shown) such as granular calcium having a diameter of about several millimeters.

The substantially rectangular water inlet 11 is intermittently formed in the circumferential wall 17c of the cup 17 along the circumferential direction. A mesh 12 is formed in the water inlet 11 by insert molding or the like, so that the additive is prevented from spilling out of the water inlet 11. In addition, a slit-like notch 18c extending upward from the lower end of the peripheral wall 18b of the cap 18 is formed. The width of the notch 18c is set to be smaller than the particle diameter of the additive, thereby preventing the additive from flowing out of the notch 18c.

In the lid 15 of the present embodiment configured as described above, the water introduced from the raw water chamber 4 through the water inlet 11 passes through the notch 18c of the cap 18 and flows into the additive storage chamber S1 to be added. The water that has come into contact with the agent again passes through the notch 18 c and flows out into the case 14.

The case 14 is partitioned in a radial direction by a substantially cylindrical cylindrical body 19 disposed at a position along the central axis Ax of the water purification cartridge 10. In this embodiment, the outer peripheral side of the cylindrical body 19 is purified by a purifier ( For example, a purification chamber S2 in which a granular or powdered activated carbon or the like) 12 is accommodated, and a filtration medium (for example, a hollow fiber membrane curved in an inverted U shape) 13 is accommodated in the cylinder 19. S3.

In such a configuration, the water introduced through the filter 16 is discharged from the drain port 10c of the lower end portion 10b via the purification chamber S2 and the filtration chamber S3 in this order. The cylindrical body 19 is fitted into a recessed portion 14 b that is recessed downward formed in the central portion of the bottom wall 14 a of the case 14, and thereby stands up and down along the central axis Ax of the water purification cartridge 10.

The purification chamber S2 is surrounded by the peripheral wall 14c of the case 14, the cylindrical body 19, the bottom wall 14a, and the filter 16, and is formed in a cylindrical shape having a substantially annular cross section. In the present embodiment, the filter 16 is formed in a ring shape and surrounds the cylindrical body 19, and the outer edge portion 16 a is fixed so as to be sandwiched between the case 14 and the lid 15. As the filter 16, a foam sheet such as a nonwoven fabric or a sponge can be suitably used, and although it can be bent and deformed, it has a self-retaining property (elasticity) that does not deform from a flat plate shape by its own weight. ing. Further, in the present embodiment, the cap 18 is attached to the upper end of the cylindrical body 19, and the inner edge portion 16b of the filter 16 is warped upward from the flange portion 18d by the flange portion 18d protruding from the cap 18 to the outside of the diameter. I am trying not to. With this configuration, even when the water purification cartridge 10 is tilted or turned upside down with the water purification cartridge 1 removed, the filter 16 is locked to the flange portion 18d and the gap is closed, so that the purification chamber S2 Can be prevented from leaking to the additive storage chamber S1 or the lid 15 side.

A communication port 19a is formed in the lower portion of the cylindrical body 19, and the purification chamber S2 and the filtration chamber S3 are communicated with each other through the communication port 19a. The water removed by adsorbing impurities to the purifier 12 in the purification chamber S2 is introduced into the filtration chamber S3 through the communication port 19a.

In the filtration chamber S3, a number of thin straw-shaped hollow fiber membranes as the filter medium 13 are accommodated in a state of being bundled and curved in a substantially inverted U shape. The water that has passed through the membrane wall of the hollow fiber membrane from the inside of the filtration chamber S3 and permeated into the membrane flows out into the lower end portion of the filtration chamber S3 through the membrane, and then flows out from the drain port 10c into the water purification chamber 5. When water passes through the membrane wall of the hollow fiber membrane, impurities contained in the water are filtered. The hollow fiber membrane as the filter medium 13 is fixed to the cylindrical body 19 with a gap filled with an adhesive (not shown) below the communication port 19a, and the hollow fiber from the inside of the filtration chamber S3 by this adhesive. Direct outflow is prevented without passing through the membrane.

By the way, when air is unintentionally collected between each part in the water purification cartridge 10, particularly between the filter 16 and the purifying agent 12, the water gravity is balanced with the air buoyancy, and the water flow path is blocked by the air. . Therefore, there is a possibility that a desired flow rate cannot be obtained and it takes time until purified water is obtained. Therefore, in the water purification cartridge 10 having such a configuration, introducing water while smoothly discharging the air existing inside during water passage leads to purification of raw water in a shorter time. Therefore, in the present embodiment, the filter 16 is disposed so as to be inclined with respect to the vertical axis Aw (gravity direction) of the main body container 2 in a use state where the water purification cartridge 10 is mounted in the recess 3b as the cartridge housing portion. ing.

Specifically, as shown in FIGS. 1 and 2, in this embodiment, the peripheral wall 3d of the recess 3b is formed to be inclined with respect to the vertical axis Aw of the main body container 2, and the water purification cartridge is formed in the recess 3b. By attaching 10, the entire water purification cartridge 10 is inclined. That is, the central axis Ax of the water purification cartridge is inclined by X degrees with respect to the vertical axis Aw of the main body container.

Also, a plurality of air vent holes 17e and 17f are formed in the top wall 17b of the cup 17 as the top wall of the lid 15. The plurality of air vent holes 17e and 17f are provided at a position higher than the water inlet 11, the air vent hole 17e is located inside the inner cylinder 17d, and the air vent hole 17f is located outside the inner cylinder 17d. Located and formed through.

Therefore, the air in the filtration chamber S3 is discharged from the air vent hole 17e through the protrusion 18a of the cap 18 and the inside of the inner cylinder 17d of the cup 17. Also, the air in the purification chamber S2 enters the additive storage chamber S1 through the filter 16 and the notch 18c of the cap 17, and rises between the peripheral wall 17c of the cup 17 and the inner cylinder 17d and passes through the air vent hole 17f. Discharged.

At this time, in the present embodiment, since the entire water purification cartridge 10 is inclined with respect to the vertical axis Aw of the main body container 2, the air S interposed between the filter 16 and the purification agent 12 can be replaced. . Then, by bringing the purifier 12 into contact with the lower side of the inclined filter 16, a flow path can be secured and water can easily penetrate into the purification chamber S2. In addition, the air S collected on the high side of the filter 16 by the passed water can be efficiently pushed out and discharged from the air vent hole 17b. As described above, according to the water purifier 1 of the present embodiment, water can be introduced while smoothly discharging the air existing inside during water flow, so that the water purifier can be stably used during the initial period of use and the latter stage of use. Purified water can be generated smoothly.

As described above in detail, in the present embodiment, the filter 16 of the water purification cartridge 10 is attached to the vertical axis Aw of the main body container 2 in a use state in which the water purification cartridge 10 is mounted in the recess 3b as the cartridge housing portion. It is made to incline with respect to. Therefore, it is possible to secure the flow path by bringing the purifier 12 into contact with the lower side of the inclined filter 16 and to easily discharge the air S collected on the higher side of the filter 16 to the outside by the passed water. it can. As a result, it becomes possible to generate purified water stably and smoothly over the initial use and late use.

Particularly, in the present embodiment, the entire water purification cartridge 10 is inclined with respect to the vertical axis Aw of the main body container 2 by inclining the peripheral wall 3d of the recess 3b. Therefore, the purifying agent 12 filled in the purification chamber 2 can be inclined and brought into contact with the filter 16. Therefore, even if the flow of water concentrates on the contact portion, it is possible to suppress the cleaning agent 12 from being washed away, and the cleaning agent 12 can be brought into contact with the filter 16 stably.

Furthermore, in the configuration in which the entire water purification cartridge 10 is inclined with respect to the vertical axis Aw of the main body container 2 in this way, the water that has passed through is concentrated on the lower side (contact portion) of the filter 16 and the purification chamber S2 Air S concentrates on the higher side of the filter 16. Therefore, the air S in the purification chamber S2 can be efficiently discharged to the outside by making good use of the difference between the gravity of water and the buoyancy of air.

In the present embodiment, the peripheral wall 3d of the recess 3b is inclined with respect to the vertical axis Aw of the main body container 2. Therefore, it is only necessary to incline only the recess 3b provided in the bottom wall 3a of the inner container (partition wall) 3, and it can be manufactured relatively easily.

Next, a modification of the water purification cartridge 10 according to the present embodiment will be described with reference to FIGS. Drawing 3 is a figure showing the 1st modification of a water purification cartridge concerning the above-mentioned embodiment.

The water purification cartridge 10A of the first modified example shown in FIG. 3 is provided with urging means for urging the purifying agent 12 toward the filter 16 in the purification chamber S2.

Specifically, in this modification, the biasing means includes a spring 21 whose one end is locked to the bottom wall 14 a of the case 14, and a mesh-like movable partition plate 22 coupled to the other end of the spring 21. And is composed of. The purifier 12 is filled on the movable partition plate 22.

In addition, since the pot type water purifier 1 is configured to purify by the gravity of water, it is preferable that the purifier (for example, activated carbon) 12 has a finer particle diameter for efficiency and performance improvement. However, since the flow rate tends to decrease when the movable partition plate 22 is filled with too fine ones, it is common to use a cleaning agent of about 10 to 32 mesh (particle diameter of about 0.5 to 2 mm). Is. However, considering the prevention of pulverized fine particles from flowing out, a somewhat larger mesh size is desirable. Therefore, in this modification, a mesh of about 100 mesh (a hole having a diameter of about 0.2 mm) is inserted or integrally molded. A partition plate 22 is used. Even if the purifying agent 12 flows out from the movable partition plate 22, in the present modification, a thin straw-like hollow fiber membrane as the filter medium 13 is disposed inside the cylindrical body 19 in the same manner as in the above embodiment. Since the filtration chamber S3 is formed, it does not leak into the water purification chamber 5.

In the water purification cartridge 10 </ b> A having such a configuration, the purification agent 12 can be reliably brought into contact with the filter 16 by the spring 21 and the movable partition plate 22 that urge the purification agent 12 toward the filter 16. As a result, the contact area between the purification agent 12 and the filter 16 can be increased, and water can be easily permeated through the purification chamber S2.

In this modification, the movable partition plate 22 and the spring 21 are used as the biasing means. However, the present invention is not limited to this. For example, a movable partition plate and a float may be used.

FIG. 4 is a view showing a second modification of the water purification cartridge according to the embodiment.

The water purification cartridge 10B of the second modified example shown in FIG. 4 is provided with a guide portion that guides the passed water toward the communication hole 19a as a hole portion in the purification chamber S2.

Specifically, in this modified example, the water collecting plate 23 as the guide portion is coupled across the bottom wall 14a and the peripheral wall 14c of the case 14, and thereby water is directed toward the communication hole 19a as the hole portion. Is to guide you.

By the way, in the configuration in which the water purification cartridge 10B is disposed to be inclined with respect to the vertical axis Aw (see FIG. 1) of the main body container as in the present modification, the case 14 on the lower side where the water is passed is inclined. There is a risk of staying in the corner 14g. However, in this modified example, since the water collecting plate 23 is provided at the corner portion 14g so as to be inclined at a predetermined angle, the so-called dead water staying at the corner portion 14g of the case 14 can be reduced. In the case of this modification, it is preferable to set the inclination angle of the water collecting plate 23 with respect to the bottom wall 14a to be equal to or larger than the inclination angle with respect to the vertical axis Aw of the water purification cartridge 10B.

In the water purification cartridge 10B having such a configuration, water can be guided toward the communication hole 19a by the water collecting plate 23 serving as a guide portion, so that the water remaining in the purification chamber S2 is suppressed and water is smoothly generated. Will be able to.

In particular, in this embodiment, the guiding portion is a water collecting plate 23 provided across the bottom wall 14a and the peripheral wall 14c of the case 14 as a peripheral wall and a peripheral wall of the water purification cartridge 10B, and the bottom wall of the water collecting plate 23 The inclination angle with respect to 14a is set to be equal to or greater than the inclination angle with respect to the vertical axis Aw of the water purification cartridge 10B. Therefore, by arranging the water purification cartridge 10B to be inclined, water is retained in the corner portion 14g of the case 14, so-called dead water can be reduced.

In this modified example, the water collecting plate 23 as the guide portion is configured by another member straddling the bottom wall 14a and the peripheral wall 14b of the case 14, but is not limited to this, for example, the bottom wall 14a of the case 14 is inclined. By doing so, the water collecting plate may be configured.

[Second Embodiment]
Next, a second embodiment of the present invention will be described with reference to the drawings. FIG. 5 is a view showing a water purifier according to the present embodiment.

Here, the main difference between the present embodiment and the first embodiment is that the main body container 2A is formed to be inclined with respect to the vertical axis Aw of the main body container 2A, so that the filter 16 is connected to the vertical axis Aw. It is that it is arranged to be inclined with respect to.

Specifically, as shown in FIG. 5, in the present embodiment, the bottom wall 2a of the main body container 2A is inclined, and the main body container 2A is placed by placing the bottom wall 2a on a horizontal plane. The whole is inclined with respect to the vertical axis Aw.

Therefore, the bottom wall portion 3a of the inner container 3a and the recess 3b as the cartridge housing portion inevitably incline with respect to the vertical axis Aw, and by attaching the water purification cartridge 10 to the recess 3b, the water purification cartridge 10 is It can be inclined with respect to the vertical axis Aw.

Even with the water purifier 1A of the present embodiment having the above-described configuration, the purifier 12 is brought into contact with the lower side of the inclined filter 16 to secure the flow path, and the collected water gathers on the higher side of the filter 16. The air S can be easily discharged to the outside. Therefore, it becomes possible to generate purified water stably and smoothly over the initial stage of use and the latter stage of use.

Further, the purifying agent 12 filled in the purification chamber 2 can be inclined and brought into contact with the filter 16. Therefore, even if the flow of water concentrates on the contact portion, it is possible to suppress the cleaning agent 12 from being washed away, and the cleaning agent 12 can be brought into contact with the filter 16 stably.

Furthermore, the water that has been passed through concentrates on the lower side (contact portion) of the filter 16 and the air in the purification chamber S2 concentrates on the higher side of the filter 16, making good use of the difference between the gravity of the water and the buoyancy of the air. Thus, the air S in the purification chamber S2 can be efficiently discharged to the outside.
