Description

Water Purifier {WATER PURIFIER}

The present invention relates to a water purifier.

In general households, pot type water purifiers are used, for example, to purify raw water such as tap water and use it as a drink. The pot-type water purifier includes a main body container having a raw water chamber located above and a water purification chamber located below, and a water purification cartridge interposed between the raw water chamber and the water purification chamber. The purified water is generated by passing the raw water through the purified water cartridge, and the generated purified water is stored in the purified water chamber.

By the way, since this pot type | mold water purifier is normally formed in the magnitude | size which can be stored in a refrigerator etc., the quantity of the purified water which can be produced at once will be limited. Therefore, the amount of purified water is obtained by repeated use. In particular, in summer, the amount of purified water used for drinking water increases, so the ability to purify the raw water in a short time has been demanded.

Thus, for example, Patent Document 1 discloses that the cloth insert is placed in contact with a purifying agent such as activated carbon by disposing a dome-shaped cloth insert between the filter cup and the lid of the water purification cartridge. It is disclosed that the surface tension of water to be removed is interrupted and the water resistance by the back pressure of air is suppressed.

Japanese Patent Laid-Open No. 10-76253

However, in the above-mentioned conventional technique, although the water resistance can be reduced at the initial stage of use, since the flow of water is concentrated on the contact portion of the cloth insert, the purifying agent that has been contacted gradually flows down and does not come into contact. Constants could not be generated smoothly.

Therefore, an object of the present invention is to obtain a water purifier capable of generating a purified water stably and smoothly during the initial use and the late use.

In the present invention, the main body container is formed with a raw water chamber for storing raw water and a purified water chamber for storing purified water, and a bottom wall of a partition wall separating the raw water chamber and the purified water chamber, and further communicating the raw water chamber and the purified water chamber. And a water purifying cartridge in which an opening is formed, and a purifying chamber filled with a purifying agent therein, the filter being disposed so as to cover the purifying chamber, and in which a water outlet is provided at a position higher than the filter. A water purifier for producing purified water with the bottom wall of the main container down, wherein the filter is inclined with respect to the vertical axis of the main container in a use state in which the purified water cartridge is attached to the cartridge accommodating portion. do.

According to the present invention, the filter of the purified water cartridge is inclined with respect to the vertical axis of the main body container in the use state in which the purified water cartridge is attached to the cartridge housing portion. Therefore, while contacting the lower side of the inclined filter with a purifying agent, a flow path is ensured, and water collected in the high side of the filter is easily discharged to the outside by the water passed through, so that it is stable during the initial use and later use. It is possible to generate integers smoothly.

EMBODIMENT OF THE INVENTION Hereinafter, embodiment of this invention is described in detail, referring drawings. In addition, the same component is contained in the following several embodiment. Therefore, below, the same code | symbol is attached | subjected to these same components, and the overlapping description is abbreviate | omitted.

[First Embodiment]

1 and 2 are diagrams showing a first embodiment of the water purifier according to the present invention.

As shown in FIG. 1, the water purifier 1 of this embodiment is comprised as a pot type | mold water purifier, and is formed in the substantially bottomed cylindrical shape similarly to the main-bottom container 2 with a substantially bottomed shape. The machine (bulb) 3 and the water purification cartridge 10 are comprised. Then, the inner container 3 is placed inside the barrel of the main container 2 so as to face the top wall portion 8 of the main container 2 so that the inside of the inner container 3 is filled with the raw water chamber 4 and the outside. Is partitioned into the water purification chamber (5).

In the bottom wall part 3a of the inner container 3, the substantially cylindrical recessed part (cartridge accommodating part) 3b which has the opening part 3c which communicates with the raw water chamber 4 and the water purification chamber 5 is formed, A substantially cylindrical water purification cartridge 10 is fitted to this recess 3b from the top to the inside. Moreover, in this state, the lower part 10b of the water purification cartridge 10 is exposed from the opening part 3c, and faces the water purification chamber 5. The raw water is injected into the raw water chamber 4 while the bottom wall portion 2a of the main body container 2 is placed downward, and the raw water passes through the purified water cartridge 10 to generate purified water. It is stored in the water purification chamber 5.

Above the raw water chamber 4, the ceiling wall part 8 in which the water supply port 8a was formed is arrange | positioned. The water supply port 8a is blocked by the top opening type lid 9 attached to the ceiling wall part 8 via a hinge 9a so that it can be opened and closed. Raw water is supplied into the raw water chamber 4 through the water supply port 8a in the state which opened the lid 9 upward.

In addition, a passage 7 extending upward from the water purification chamber 5 is formed between the side wall portion 3e of the inner container 3 and the main body container 2, and the main body container 2 or the ceiling wall part is formed. In 8, the injection hole 7a is formed in the position used as the upper end part of the channel | path 7. In this embodiment, the main body container 2 is inverted so that the inlet 7a is downward (in FIG. 1, the main body container 2 is turned clockwise), whereby the purified water stored in the water purification chamber 5 is passaged. It discharges from the injection port 7a via (7). In addition, in this embodiment, the injection opening 7a is closed by the upper opening type lid 20 supported by the main body container 2 or the top wall part 8 so that rotation is possible so that opening and closing is possible. In this case, when the main body container 2 is inclined, the lid body 20 can be rotated by its own weight, the dynamic pressure of water, or the like, so that the injection port 7a can be opened.

As shown in FIG. 2, the purified water cartridge 10 covers 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 the purification chamber S2 is covered. The filter 16 is coupled to cover the opening 14e of the case 14 and is provided with a lid 15 in which a water tap 11 is formed at a position higher than the filter 16.

The lid 15 is provided at the lower end of the inner cylinder 17d and the cup 17 in which the inner cylinder 17d extends downward along the central axis Ax of the water purification cartridge 10 from the top wall 17b of the outer cylinder 17a. The cap 18 which forms the additive accommodating chamber S1 in the inside by inserting the protrusion part 18a is provided. In this additive storage chamber S1, additives (not shown), such as granular calcium of about several millimeters in diameter, are accommodated, for example.

On the circumferential wall 17c of the cup 17, a substantially rectangular waterway 11 is intermittently formed along the circumferential direction. In this water pipe 11, the mesh 12 is comprised by insert molding etc., and the overflow of the additive from the water pipe 11 is suppressed. Moreover, the slit-shaped notch 18c extended upward from the lower end is formed in the circumferential wall 18b of the cap 18. As shown in FIG. The width | variety of the notch 18c is set smaller than the particle diameter of an additive, and it is suppressed that an additive flows out from the notch 18c by this.

In the lid 15 of this embodiment comprised in this way, the water introduce | transduced from the raw water chamber 4 through the water tap 11 flows in through the notch 18c of the cap 18, and flows into the additive accommodation chamber S1. The water in contact with the additive passes through the notch 18c again and flows out into the case 14.

The case 14 is partitioned in the radial direction by a substantially cylindrical cylinder 19 disposed at a position along the central axis Ax of the water purification cartridge 10. In the present embodiment, the outer circumference of the cylinder 19 The side is made into the purification | cleaning chamber S2 in which the purification agent (for example, granular or powdery activated carbon etc.) 12 was accommodated, and the inside of the cylinder of the cylinder 19 was a filter medium (for example, the hollow fiber membrane curved in an inverted U shape) ( 13) is taken as filtration chamber 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 penetrated into the recessed part 14b which was dug downward formed in the center part of the bottom wall 14a of the case 14, and, thereby, stands vertically along the central axis Ax of the water purification cartridge 10, and It is installed.

Purification chamber S2 is surrounded by the circumferential wall 14c, the cylinder 19, the bottom wall 14a, and the filter 16 of the case 14, and is formed in the cylindrical shape which has a substantially circular cross section. In this embodiment, the filter 16 is formed in ring shape, surrounds the cylinder 19, and is fixed so that the outer edge part 16a may be pinched | interposed between the case 14 and the lid 15. FIG. As this filter 16, foam sheets, such as a nonwoven fabric and a sponge, can be used suitably, and it can be warped and deforms, but it has the self-shaping | molding property (elasticity) of the grade which does not deform | transform as flat form also by its own weight. Moreover, in this embodiment, the cap 18 is attached to the upper end of the cylinder 19, and the internal edge part of the filter 16 is made by the flange part 18d which protruded outward from this cap 18 to the diameter outside. 16b) is not bent upwards than the flange portion 18d. With such a configuration, even when the water purifying cartridge 10 is tilted or inverted in the state of being removed from the water purifier 1, since the filter 16 is caught by the flange portion 18d, the gap is clogged. The purification agent 12 can be suppressed from leaking to the additive storage chamber S1 and the lid 15 side.

The communication port 19a is formed in the lower part of the cylinder 19, and the communication port 19a communicates with the purification chamber S2 and the filtration chamber S3. The water removed by adsorbing impurities to the purifying agent 12 in the purifying chamber S2 is introduced into the filtering chamber S3 through the communication port 19a.

In the filtration chamber S3, many thin straw-shaped hollow fiber membranes as the filter medium 13 are accommodated in the state which was bundled and curved in substantially inverted U shape. Water passing through the membrane wall of the hollow fiber membrane in the filtration chamber S3 and permeated into the membrane flows out through the membrane to the lower end of the filtration chamber S3 and flows out from the drain port 10c to the water purification chamber 5. When water passes through the membrane wall of the hollow fiber membrane, impurities contained in the water are filtered out. The hollow fiber membrane as the filter medium 13 is fixed to the cylinder 19 while filling the clearance gap with an adhesive agent (not shown) below the communication port 19a, and by this adhesive agent, the hollow fiber membrane in filter chamber S3. Direct outflow is prevented without passing through.

However, if air is inadvertently collected between each part in the purified water cartridge 10, in particular, between the filter 16 and the purifier 12, the gravity of the water and the buoyancy of the air are balanced and the water flow path is blocked by the air. Therefore, a desired flow rate may not be obtained, and it may take time before the purified water is obtained. Therefore, in the purified water cartridge 10 having such a configuration, introducing water while smoothly discharging air existing therein at the time of water passage leads to purifying the raw water in a shorter time. Therefore, in this embodiment, the filter 16 is inclined with respect to the vertical axis Aw (gravity direction) of the main body container 2 in the use state which mounted the water purification cartridge 10 to the recessed part 3b as a cartridge accommodating part. I'm trying to place it.

Specifically, as shown in FIGS. 1 and 2, in the present embodiment, the main wall portion 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 recess 3b is provided. ), The whole water purification cartridge 10 is inclined. That is, X of the central axis Ax of the purified water cartridge is inclined with respect to the vertical axis Aw of the main body container.

In addition, a plurality of air discharge holes 17e and 17f are formed in the ceiling wall 17b of the cup 17 as the ceiling wall of the lid 15. The plurality of air discharge holes 17e and 17f are provided at a position higher than the raceway 11, and the air discharge holes 17e are located inside the inner cylinder 17d, and the air discharge holes 17f are provided. ) Is located outside the inner cylinder 17d and formed through.

Therefore, the air in filtration chamber S3 is discharged | emitted from the air discharge hole 17e via the protrusion part 18a of the cap 18 and the inside of the cylinder of the inner cylinder 17d of the cup 17. In addition, 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 circumferential wall 17c of the cup 17 and the inner cylinder 17d. It is discharged from the air discharge hole 17f.

At this time, in this embodiment, since the whole 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 purifier 12 can be replaced. do. By contacting the purifying agent 12 with the lower side of the inclined filter 16, a flow path can be secured and water can be easily infiltrated into the purifying chamber S2. In addition, the air S collected on the high side of the filter 16 can be efficiently pushed to the outside by the water passed through and discharged from the air discharge hole 17b. As described above, according to the water purifier 1 of the present embodiment, since water can be introduced while smoothly discharging the air present in the water passage, the purified water can be stably and smoothly generated during the initial use and the later use. have.

As described above in detail, in the present embodiment, the filter 16 of the purified water cartridge 10 is placed in a main body container in a used state in which the purified water cartridge 10 is mounted on the recessed portion 3b as the cartridge housing portion. It is arrange | positioned inclined with respect to the vertical axis Aw of 2). Therefore, the purifier 12 is brought into contact with the lower side of the inclined filter 16 to secure the flow path, and the air S collected on the high side of the filter 16 can easily be discharged to the outside by the water passed through. Can be. As a result, it is possible to stably and smoothly generate constants during the initial use and the late use.

In particular, in the present embodiment, the entire wall of the purified water cartridge 10 is inclined with respect to the vertical axis Aw of the main body container 2 by inclining the circumferential wall portion 3d of the concave portion 3b. Therefore, the purification | cleaning agent 12 filled in the purification chamber 2 can incline and contact the filter 16. FIG. Therefore, even if the flow of water is concentrated in the contact portion, the purification agent 12 can be prevented from flowing down, and the purification agent 12 can be brought into contact with the filter 16 stably.

Moreover, in the structure which inclines the whole water purification cartridge 10 with respect to the vertical axis | shaft Aw of the main body container 2 in this way, the water passed through is concentrated in the low side (contact part) of the filter 16, and Air S is concentrated on the high side of the filter 16. Therefore, the difference between the gravity of water and the buoyancy of air can be effectively used, and the air S in the purification chamber S2 can be efficiently discharged to the outside.

Moreover, in this embodiment, it is set as the structure which inclines the main wall part 3d of the recessed part 3b with respect to the perpendicular axis Aw of the main body container 2. As shown in FIG. Therefore, it is only necessary to incline only the recessed part 3b provided in the bottom wall part 3a of the inner container (b partition) 3, and it can manufacture relatively easily.

Next, with reference to FIG. 3 and 4, the modification of the water purification cartridge 10 which concerns on this embodiment is demonstrated. 3 is a diagram showing a first modification of the purified water cartridge according to the embodiment.

The purified water cartridge 10A of the first modification shown in FIG. 3 is provided with elastic pressing means for elastically pressing the purifying agent 12 toward the filter 16 in the purification chamber S2.

Specifically, in this modification, the elastic pressing means includes a spring 21 having one end hooked to the bottom wall 14a of the case 14 and a movable partition plate having a mesh shape that is coupled to the other end of the spring 21. It consists of 22. The purifying agent 12 is filled on the movable partition plate 22.

Moreover, in the pot type water purifier 1, since it is the structure which purifies with the gravity of water, it is efficient for the purifier (for example, activated carbon) 12 to be finer in particle size, and it is preferable for performance improvement. However, since the flow rate tends to decrease when too small a thing is filled in the movable partition plate 22, it is common to use the purification | cleaning agent of about 10 mesh to about 32 mesh (particle size of about 0.5 millimeter to 2 millimeters). However, in consideration of the prevention of crushed fine particles, a slightly larger mesh is preferable, so in this modification, a movable partition plate in which a mesh of about 100 mesh (a hole having a diameter of about 0.2 millimeters) is inserted or integrally molded is inserted. (22) is used. Moreover, even if the purifying agent 12 flows out from the movable partition plate 22, in this modification, it carried out similarly to the said embodiment, and the thin straw-shaped hollow fiber membrane as the filter medium 13 is arrange | positioned inside the cylinder 19. Since filtration chamber S3 is formed, it does not leak into the purified water chamber 5.

In the clean water cartridge 10A having such a configuration, the purifier 12 is secured to the filter 16 by the spring 21 and the movable partition plate 22 which pressurize the purifier 12 toward the filter 16. Can be contacted. As a result, it is possible to increase the contact area between the purifier 12 and the filter 16 so that water can be easily infiltrated by the purifying chamber S2.

In addition, in this modification, although the movable partition plate 22 and the spring 21 were used as the elastic press means, it is not limited to this, For example, a movable partition plate, a float, etc. may be used.

4 is a diagram showing a second modification of the purified water cartridge according to the embodiment.

The purified water cartridge 10B of the second modification shown in FIG. 4 is provided with a guiding portion for guiding water passed through the communication hole 19a as a hole in the purification chamber S2.

Specifically, in the present modification, the collecting plate 23 as the induction part is coupled over the bottom wall 14a and the main wall 14c of the case 14, whereby toward the communication hole 19a as the hole part. It is supposed to guide the water.

By the way, in the structure which arrange | positions the water purification cartridge 10B with respect to the vertical axis Aw (refer FIG. 1) of a main body container like this modification, the edge of the case 14 in which the water passed through becomes the inclined low side ( It may stay in 14g). However, in the present modification, since the collecting plate 23 is inclined at a predetermined angle to the corner portion 14g, the so-called shot water remaining in the corner portion 14g of the case 14 can also be reduced. . In addition, in the case of this modification, it is preferable to set the inclination angle of the collection plate 23 with respect to the bottom wall 14a more than the inclination angle with respect to the vertical axis Aw of the water purification cartridge 10B.

In the purified water cartridge 10B having such a configuration, since the water can be guided toward the communication hole 19a by the water collecting plate 23 as the guide portion, the purified water can be smoothly generated by suppressing the remaining water in the purification chamber S2. It becomes possible.

In particular, in the present embodiment, the induction part is a collecting plate 23 provided over the bottom wall 14a and the main wall 14c of the case 14 as the bottom wall and the main wall of the water purification cartridge 10B. The inclination angle with respect to the bottom wall 14a is set to more than the inclination angle with respect to the vertical axis Aw of the water purification cartridge 10B. For this reason, the so-called dead water in which water stays in the edge part 14g of the case 14 can be reduced by arrange | positioning the water purification cartridge 10B.

In addition, in this modification, although the collection plate 23 as an induction part was comprised from the other member which spreads over the bottom wall 14a and the main wall 14b of the case 14, it is not limited to this, For example, the case 14 The water collecting plate may be constituted by inclining the bottom wall 14a of the bottom wall.

[Second Embodiment]
