First, with reference to FIG. 1, the schematic structure of the water purifier 1 which concerns on this embodiment is demonstrated. This water purifier 1 is configured as a photo type water purifier. In the cylinder of the substantially bottomed cylindrical photo case 2, the substantially bottomed cylindrical partition 3 is housed, and the partition 3 is used to store the cylinder of the photo case 2. I is partitioned into the raw water chamber 4 which comprises about half of the upper part, and the water purification chamber 5 which forms about half of the lower side.

In the bottom wall 3a of the partition 3, a substantially cylindrical recess 3b provided concave downward is formed. The substantially cylindrical water purification cartridge 6 is inserted into this recessed part 3b from the top to the inside, and is fitted. An opening 3d is formed in the inner wall 3c of the recess 3b.

In the state where the purified water cartridge 6 is fitted into the recessed portion 3b, the upper portion 6a of the purified water cartridge 6 is exposed in the raw water chamber 4, and the upper portion 6a is formed in the case 7. The first water tap 7a and the second water tap 7b face the raw water chamber 4. The second water hole 7b is provided near the bottom wall 3a. Moreover, in this state, the lower end part 6b of the water purification cartridge 6 is exposed in the water purification chamber 5 from the opening 3d, and the outlet 7c formed in the case 7 in this lower end part 6b is purified water. It is aimed toward the thread 5. The raw water in the raw water chamber 4 is introduced into the purified water cartridge 6 from the first water tap 7a and the second water tap 7b and at least purified, and then from the outlet 7c into the water purification chamber 5. Discharged.

Above the raw water chamber 4, the ceiling wall 8 in which the water supply port 8a was formed is arrange | positioned. The water inlet 8a is closed by the upper opening lid 9 attached to the ceiling wall 8 so as to be openable and closed. The raw water is supplied into the raw water chamber 4 through the water supply port 8a with the lid 9 opened upward.

In addition, a passage 10 extending upward from the water purification chamber 5 is formed between the side wall 3e of the partition 3 and the photo case 2, and the photo case 2 or the ceiling wall is formed. In 8, the water inlet 10a is formed in the position used as the upper end part of the channel | path 10. As shown in FIG. In this embodiment, the photo case 2 is inclined so that the water inlet 10a is downward (in FIG. 1, the photo case 2 is inclined clockwise), and the purified water stored in the water purification chamber 5 is reduced. , And discharged from the water inlet 10a via the passage 10. In addition, in this embodiment, the spout 10a is closed by the upper opening type lid 11 supported rotatably by the photo case 2 or the ceiling wall 8 so that opening and closing is possible. In this case, when the photo case 2 is inclined, the lid 11 can be rotated by its own weight, the dynamic pressure of water, or the like, so that the water inlet 10a can be opened.

Next, with reference to FIGS. 2-4, the structure of the purified water cartridge 6 is demonstrated. The water purification cartridge 6 is formed in a substantially cylindrical shape, and the cylindrical central axis Ax (see FIGS. 1 and 2) is used in a posture along the vertical direction. The case 7 has an upper case 12 that forms an upper portion and a lower case 13 that forms a lower portion in a use state, and the lower edge of the upper case 12 and the upper edge of the lower case 13 are mutually coupled to each other. The outline shape of the substantially cylindrical shape is shown. In addition, below, the up-down direction, the axial direction, the circumferential direction, and the radial direction are prescribed | regulated based on the cylindrical shape of the water purification cartridge 6 in a use state.

The case 7 is divided into three large spaces in the up-down direction (axial direction) by the partition wall 14 and the sheet 15 disposed below the partition wall 14 at intervals. The uppermost part is an additive accommodating chamber S1 in which the additive 16 is accommodated, the purification chamber S2 in which the lowermost part purifies water, and the intermediate part S3 as a mixing part.

The additive storage chamber S1 is formed surrounded by the upper case 12 and the partition wall 14. The upper case 12 includes a circumferential wall 12a (first cylindrical sidewall) forming the upper circumferential wall of the case 7, a ceiling wall 12b constituting the ceiling wall of the case 7, and a ceiling wall ( It has the inner cylinder 12c extended downward along the center axis Ax of the water purification cartridge 6 from the center part of 12b). And the partition 14 is attached to this upper case 12 so that the lower part in the cylinder may be blocked. That is, in this embodiment, an additive is formed as a substantially annular cross section surrounded by a circumferential wall 12a, a ceiling wall 12b, an inner cylinder 12c, and a partition wall 14 in the cylinder of the upper case 12. The storage chamber S1 is formed. In this additive storage chamber S1, additives 16, such as granular calcium of about several millimeters in diameter, are accommodated, for example.

As shown in FIG. 3, FIG. 4, etc., the peripheral wall 12a is provided with the substantially rectangular 1st water tool 7a. The water-permeable mesh 17 is provided in insert molding etc. in this 1st water flow tool 7a, and the overflow of the additive 16 from the 1st water flow tool 7a is suppressed. In addition, a slit-shaped notch 12d extending upward from the lower end thereof is formed in the inner cylinder 12c. The width | variety of the notch 12d is set smaller than the particle diameter of the additive 16, and it is suppressed that the additive 16 overflows from the notch 12d. In addition, in this embodiment, the position of the axial direction of the upper edge 12e of the notch 12d, and the position of the axial direction of the upper edge 12f of the 1st waterway tool 7a become substantially the same.

Moreover, the protrusion part 14b which protrudes in a substantially conical shape is formed in the center part of the bottom wall part 14a of the partition 14, and the inner part 12c protrudes upwards in the center part of this protrusion part 14b. The tube part 14c through which () is inserted is formed. The bottom wall portion 14a is formed with a plurality of slits 14d extending radially from the central axis Ax of the purified water cartridge 6 as an outlet from the additive storage chamber S1. The width of this slit 14d is set smaller than the particle size of the additive 16, and the overflow of the additive 16 from the slit 14d is suppressed by this.

In the additive storage chamber S1 having the above constitution, the additive 16 is eluted from the raw water chamber 4 to the raw water introduced into the additive storage chamber S1 through the first water hole 7a, and the additive is added. The extracted water flows out from the additive storage chamber S1 to the intermediate chamber S3 through the slit 14d of the partition wall 14.

Here, in this embodiment, the air storage part Aa which traps air is formed in the upper part of the additive storage chamber S1, and, thereby, in the air storage part Aa, ie, of the additive storage chamber S1, About the additive 16 which exists in the upper part, it is made not to immerse in water. That is, the recessed part 18 which consists of the circumferential wall 12a, the ceiling wall 12b, and the inner cylinder 12c only opens downward, and there is no way from which air is extracted upwards, and therefore, the 1st Even if water penetrates into the additive storage chamber S1 from the water supply port 7a, and the upper portion 6a of the water purification cartridge 6 is all locked to the water stored in the raw water chamber 4 (that is, the state of being submerged). The air is stored in the concave portion 18, so that the blood of the additive 16 in the air storage portion Aa can be prevented. In this embodiment, the position of the upper edge 12e, 12f of the notch 12d and the 1st waterway 7a normally becomes the upper limit L of the submerged area | region Aw, and this upper limit L is this The additive 16 located below is submerged in water, and the additive 16 located above the upper limit L is not submerged in water.

In such a configuration, when the additive 16 located below is immersed in water and eluted, the additive 16 located above drops downward by gravity to automatically replenish the submerged region Aw. Therefore, since the additive 16 accommodated in the additive accommodating chamber S1 can be used sequentially from the one disposed below, the additive 16 contained in the water purification cartridge is submerged or watered as a whole. It becomes easy to take longer the usable period of time, and it becomes easy to suppress the difference in density | concentration of an additive smaller in the initial use and the late use of the purified water cartridge 6. Moreover, according to this embodiment, the immersion height of the additive 16 can be set according to the height of the immersion area | region Aw, and, thereby, the maximum value of additive concentration can be set. That is, the additive 16 can be suppressed from eluting in water more than necessary.

As shown to FIG. 3, FIG. 4, the lower part of the circumferential wall 12a of the upper case 12 which forms the circumferential wall of the intermediate | middle chamber S3 is the 2nd water tap 7b at substantially constant intervals in the circumferential direction. A plurality of are formed. Therefore, the raw water is introduced into the intermediate chamber S3 from the raw water chamber 4 through the second tap 7b, and the water to which the additive is added from the additive storage chamber S1 through the slit 14d is added. It introduces and these water is introduce | transduced into the adsorption process chamber S21 (purification chamber S2) arrange | positioned under the intermediate chamber S3. That is, in the present embodiment, the raw water introduced into the intermediate chamber S3 from the second water hole 7b bypasses the additive storage chamber S1. Thus, by classifying the water flowing in the additive storage chamber S1 and the water bypassing the additive storage chamber S1, the flow rate of the water flowing in the additive storage chamber S1 and the additive storage chamber S1 are separated. The flow rate of the water to bypass can be set independently, thereby making it easy to increase the adjustment accuracy of the additive concentration. In this way, water is introduced into the intermediate chamber S3 from the second water hole 7b and water is introduced from the first water hole 7a through the additive storage chamber S1 as described above. Therefore, the intermediate chamber S3 mixes the water introduced from the first water tap 7a and the water introduced from the second tap 7b.

In addition, in this embodiment, the 2nd water tap 7b is arrange | positioned below the 1st water tap 7a. For this reason, the water head difference by the difference of the height of the 1st water tap 7a and the 2nd water tap 7b, and the bottom wall of the partition body 3 at the beginning supplied to the raw water chamber 4 Due to the dynamic pressure of the water reaching the second tap 7b at the position close to (3a), water is more likely to enter from the second tap 7b as compared to the first tap 7a. Therefore, especially in the beginning supplied to the raw water chamber 4, the flow volume of the water in the 1st tap 7a can be made comparatively small, and it becomes easy to adjust the flow volume of the water in the additive accommodation chamber S1 small.

Moreover, in this embodiment, since the additive accommodation chamber S1 was arrange | positioned above the 2nd water tap 7b, after the water level of the raw water chamber 4 becomes lower than the lower end of the additive storage chamber S1, it is 2nd. Water is introduced into the purified water cartridge 6 only from the water purifier 7b, and the water downstream of the intermediate chamber S3 is prevented by the water not passing through the additive storage chamber S1 and the additive 16 is not included. The discharge of the additive 16 in the intermediate chamber S3, the purification chamber S2, or the like can be promoted to suppress the additive 16 from remaining. Therefore, at the next use, the residual additive 16 suppresses the additive concentration from being higher than the set value, and the desired additive concentration is easily obtained.

Purification chamber S2 arrange | positioned under intermediate chamber S3 is divided radially by the substantially cylindrical cylinder 19 arrange | positioned in the position along the central axis Ax of the water purification cartridge 6, In this embodiment, the outer peripheral side of the cylinder 19 is made into the adsorption process chamber S21 in which the adsorbent (for example, granular or powdered activated carbon, etc.) 20 was accommodated, and the inside of the cylinder of the cylinder 19 was filtered. For example, it is set as the filtration process chamber S22 in which the hollow fiber membrane etc. which were curved in inverted U shape were accommodated. In such a configuration, the water introduced from the intermediate chamber S3 is discharged from the outlet 7c of the lower end 6b via the adsorption treatment chamber S21 and the filtration treatment chamber S22 in this order. The cylinder 19 is inserted into the recessed recessed part 13b recessed downward which was formed in the center part of the bottom wall 13a of the lower case 13 which forms the bottom wall of the case 7, and thereby the water purification cartridge It is installed upright along the central axis Ax of (6).

The adsorption process chamber S21 is surrounded by the circumferential wall 13c of the lower case 13 which forms the lower part of the circumferential wall of the case 7, the cylinder 19, the bottom wall 13a, and the sheet 15, and is approximately It is formed in the cylindrical shape which has an annular cross section. The sheet 15 can be comprised, for example from a nonwoven fabric. In the present embodiment, the sheet 15 is formed in a ring shape to surround the cylinder body 19 so that the outer edge portion 15a is sandwiched between the upper case 12 and the lower case 13. It is fixed to the case 7. On the other hand, the inner edge 15b is a free end, so that water is introduced into the adsorption treatment chamber S21 from the intermediate chamber S3 via a gap between the inner edge 15b and the cylinder 19. In addition, you may comprise the sheet | seat 15 with a water permeable material, and let water permeate. In addition, in this embodiment, the cap 22 is attached to the upper end of the cylinder 19, and the inner edge part of the sheet | seat 15 is provided by the flange part 22a which protrudes radially outward from this cap 22. 15b) is prevented from curling up above the flange portion 22a. With this configuration, even when the water purifying cartridge 6 is tilted or inverted in the state of being removed from the water purifier 1, the sheet 15 is caught by the flange portion 22a and the gap is clogged. From S21, the adsorbent 20 can be suppressed from leaking to the intermediate chamber S3 side.

The communication port 19a is formed in the lower part of the cylinder 19, and the adsorption process chamber S21 and the filtration process chamber S22 communicate with this communication port 19a. Water removed by adsorbing impurities to the adsorbent 20 in the adsorption treatment chamber S21 is introduced into the filtration treatment chamber S22 through the communication port 19a.

In the filtration process chamber S22, many thin straw-shaped hollow fiber membranes as the filter medium 21 are accommodated in the state which bundled and curved in substantially inverted U shape. Water that has permeated through the membrane wall of the hollow fiber membrane from the filtration chamber S22 and flows into the membrane passes through the membrane to the lower end of the filtration chamber S22 and flows out from the outlet 7c 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 21 is fixed to the cylinder 19 while the gap is filled with an adhesive (not shown) below the communication port 19a, and is hollowed out from the filtration processing chamber S22 by this adhesive. Direct leaks are impeded without passing through the desert.

As a result of diligent studies by the inventors of the purified water cartridge 6 having the above-described configuration, it has been found that the additive concentration of the water changes in accordance with the flow rate of the water flowing in the additive storage chamber S1. As an example, in the case where the granular calcium agent is used as the additive 16, as the flow rate of the water flowing in the additive containing chamber S1 is increased, the stirring effect due to the water flow increases, and the water is added to the water in the additive containing chamber S1. The amount of the additive to be mixed increases, and the additive concentration of the water after the water that has passed through the additive containing chamber S1 and the water introduced into the purified water cartridge 6 from the second tap 7b is joined, and the purified water cartridge 6 It has been found that the concentration of additives in water discharged from) increases. So, in this embodiment, the flow rate ratio of the water introduced from the 1st water tap 7a and the water introduced from the 2nd tap 7b to the case 7 is variablely set according to the position with respect to the case 7. The movable member 23 was attached, and by adjusting the position of the movable member 23, the additive concentration in the water (clean water) passed through the purified water cartridge 6 could be set variably. Specifically, in the present embodiment, the movable member 23 variably sets the opening area of the first channel 7a and changes the flow rate of the water flowing in the additive storage chamber S1 to thereby adjust the first frequency. The flow rate ratio of the water introduced from the sphere 7a and the water introduced from the second tap 7b is variably set.

In this embodiment, as shown in FIGS. 2-4, the substantially bottomed cylindrical movable member 23 which covers the outer periphery of the upper case 12 from upper direction rotates along the circumferential direction of the upper case 12. As shown in FIG. It is attached as possible. The circumferential wall 23a (second cylindrical sidewall) of the movable member 23 covers the circumferential wall 12a of the upper case 12 with a slight gap and moves along the circumferential wall 12a. In the circumferential wall 23a, a substantially rectangular notch 23c is formed as an opening from the lower end edge 23b upward.

On the outer surface of the circumferential wall 12a of the upper case 12, a plurality of (3 in this embodiment) line-shaped protrusions 12g along the circumferential direction are installed substantially parallel at regular intervals vertically, while being movable The protrusion 23d is provided on the inner surface of the circumferential wall 23a of the member 23 and the protrusion 23d is attached to the line protrusion 12g in a state where the movable member 23 is attached to the upper case 12. In addition to engaging in the axial direction, the projection 23d is guided in the circumferential direction by the line-shaped projection 12g. Moreover, the notch 12h which allows relative movement of the projection 23d in the axial direction is formed in the line-shaped protrusion 12g. Thus, as shown in FIG. 3, the upper case 12 and the movable member 23 are brought close to each other in the axial direction until the protrusions 23d and the notches 12h are aligned with each other. By making the relative rotation in the circumferential direction, the projection 23d enters between the linear projections 12g, and the movable member 23 can be attached to the upper case 12 (case 7), and the movable member 23 is provided. Becomes rotatable along the circumferential direction of the upper case 12. Further, a plurality of projections are provided in the grooves between the line projections 12g at predetermined intervals, and the click feeling is caused by passing the projection at a predetermined position in the circumferential direction with respect to the first raceway 7a of the movable member 23. It is more preferable to generate | occur | produce and make it the reference | standard which sets the opening area of the 1st water tap 7a.

In such a configuration, as shown in FIG. 4, when the position in the circumferential direction of the movable member 23 is changed, the notch 23c and the first water tap 7a overlap each other in accordance with the movement amount of the circumferential wall 23a. Since the area to be lost changes or the range of the first raceway 7a covered by the circumferential wall 23a increases and decreases, the opening width w and the opening area of the first raceway 7a (the raw water chamber ( 4) can be set to a variable width and area). That is, the movable member 23 functions as a shielding member which shields the 1st water tap 7a.

FIG. 4A is a state in which the whole area of the first water tap 7a is opened. In this state, since the flow rate of the water which flows into the additive accommodation chamber S1 from the 1st water tap 7a is comparatively large, the additive concentration of the water which flows out from the additive accommodation chamber S1 becomes high.

In FIG.4 (b), about half of the 1st water tap 7a is blocked by the circumferential wall 23a of the movable member 23, and about half is opened. In this state, the flow rate of the water in the additive accommodation chamber S1 decreases compared with the case of FIG. 4A, and the flow rate of the water introduced from the 1st tap 7a and the water introduced from the 2nd tap 7b. In the ratio, the ratio of the flow rate of the water introduced from the first tap hole 7a is lower than in the case of Fig. 4A, and the additive concentration of the water flowing out of the additive storage chamber S1 is lowered by that amount.

Thus, according to the purified water cartridge 6 which concerns on this embodiment, the additive concentration of water is changed by changing the relative rotation position (lateral position) around the center axis Ax with respect to the case 7 of the movable member 23. As shown in FIG. Can change.

In addition, if air is inadvertently stored between the respective parts in the water purification cartridge 6, especially between the intermediate chamber S3 and the seat 15 and the adsorbent 20, the gravity applied to the water and the buoyancy of the air are balanced. Since the flow path of water is clogged with air, a desired flow rate may not be obtained, and it may take time until the purified water is obtained, or the desired additive concentration may not be obtained. Therefore, in this embodiment, the air extraction passage is formed along substantially the central axis Ax of the purified water cartridge 6.

Specifically, a substantially cylindrical central cylinder portion 23f extending downward and entering the cylinder of the inner cylinder 12c is formed in the central portion of the ceiling wall 23e of the movable member 23, and the central cylinder portion 23f is formed. In the inner side (upper side), a through hole 23g penetrating the ceiling wall 23e is formed. This through hole 23g becomes the air extraction hole of the purified water cartridge 6.

The cap 22 fitted to the upper end of the cylinder 19 has a conical portion 22b that is tapered as it faces upward, and a cylindrical portion 22c extending upward from the top of the cone portion 22b. The tip end of the cylindrical portion 22c extends to the vicinity of the lower end of the central cylindrical portion 23f. Therefore, the air in the filtration processing chamber S22 is discharged from the through hole 23g via the inside of the cone 22b, the cylinder 22c, and the center cylinder 23f.

The air in the adsorption treatment chamber S21 and the intermediate chamber S3 moves along the protrusion 14b of the partition 14 to the center axis Ax side of the water purification cartridge 6, and passes through the notches 12d to the inside. It enters into the cylinder of the cylinder 12c, and enters into the cylinder of the said center cylinder part 23f from the opening of the lower end of the center cylinder part 23f, and is discharged | emitted from the through hole 23g.

The air in the additive storage chamber S1 passes through the inside of the cylinder of the inner cylinder 12c and the cylinder of the central cylinder portion 23f from the notch 12d, except that the air is stored in the air storage portion Aa. It discharges from the through hole 23g.

As described above, in the present embodiment, in the case 7, the first water tap 7a for introducing water into the additive storage chamber S1 and the additive storage chamber S1 are bypassed to purify the chamber S2. The intermediate chamber S3 which is a mixing part which mixes the water introduced from the 2nd water tap 7b and water introduced from the 1st water tap 7a, and the water introduced from the 2nd water tap 7b is formed In addition, the movable member which sets the flow rate ratio of the water introduced from the 1st tap opening 7a and the water introduced from the 2nd tap opening 7b to the case 7 according to the position with respect to the case 7 (23) was attached. Therefore, the additive concentration can be easily set by the movable member 23 without replacing the purified water cartridge 6. In addition, when calcium etc. are used as an additive, the hardness of water can be variably set.

Moreover, in this embodiment, the movable member (1) is formed in the circumferential wall 12a of the upper case 12 as the outer wall of the case 7, and covers the outer side of the circumferential wall 12a. The first raceway 7a is blocked by the peripheral wall 23a of 23. Therefore, by setting the opening area of the 1st water tap 7a variably by the movable member 23, the additive concentration can be variably set and the movable member 23 arrange | positions so that the outer side of the case 7 may be covered. As a result, the user can easily operate the movable member 23.

Moreover, in this embodiment, at least the upper part of the case 7 is formed in substantially cylindrical shape, and the 1st channel | tool 7a is formed in the circumferential wall 12a, and the movable member 23 is the said case 7 Is formed in a cylindrical shape with a bottom covering from above, and the circumference | surroundings of the case 7 are rotated so that the 1st water tap 7a may be blocked by the circumferential wall 23a of the movable member 23. As shown in FIG. Therefore, the movable member 23 can be obtained as a relatively simple structure, and the movable member 23 can be stably supported by the case 7. Moreover, by relatively simple operation of moving the movable member 23 relative to the case 7 (moving in the lateral direction), the opening area of the first water tap 7a is changed to change the additive concentration. Can be. In addition, as in the present embodiment, when the water purifying cartridge 6 is inserted into the photo case 2 of the water purifier 1 from above, the movable member ( 23) It is convenient to be able to operate.

Moreover, in this embodiment, the case 7 was provided with the 2nd water tap 7b which bypasses the additive storage chamber S1 and introduces water into the purification chamber S2. Therefore, by dividing the water passing through the additive containing chamber S1 and the water bypassing the additive containing chamber S1, the flow rate of the water flowing in the additive containing chamber S1 and the additive containing chamber S1 are bypassed. The flow rate of the passing water can be set independently, thereby making it easy to increase the adjustment accuracy of the additive concentration.

Moreover, in this embodiment, the 1st water tap 7a was arrange | positioned above the 2nd water tap 7b. For this reason, the head difference caused by the difference between the heights of the first raceway 7a and the second raceway 7b and the bottom wall 3a of the partition wall 3 are initially supplied to the raw water chamber 4. By the dynamic pressure of the water reaching the 2nd water tap 7b located in the near position, water becomes easier to enter from the 2nd water tap 7b compared with the 1st water tap 7a. Therefore, especially in the beginning supplied to the raw water chamber 4, the flow volume of the water in the 1st tap 7a can be made comparatively small, and it becomes easy to adjust the flow volume of the water in the additive accommodation chamber S1 small. Therefore, in the case of this embodiment, it becomes easy to adjust an additive concentration lower. Moreover, according to such a structure, it becomes easy to arrange | position the movable member 23 which changes the opening area of the 1st water tap 7a in the upper part of the water purification cartridge 6. As shown in FIG. Therefore, as in the present embodiment, when the water purifying cartridge 6 is inserted into and mounted in the photo case 2 of the water purifier 1, the movable member ( 23) It is easy to operate and convenient.

Moreover, in this embodiment, the air storage part Aa is formed in the upper part in the additive storage chamber S1, and the additive 16 is the 1st in the submerged area | region Aw which becomes lower than the said air storage part Aa. It was made to immerse in the water introduced through the water hole 7a, and the additive 16 was accommodated in the additive storage chamber S1 from the part which becomes the submerged area Aw to the part which becomes the air storage part Aa. . In such a configuration, the additive 16 in the air reservoir Aa can be kept in a state of not being submerged or avoided. Then, when the additive 16 in the submerged area Aw is immersed in water and eluted, the additive 16 located above it drops downward by gravity to automatically replenish the submerged area Aw. Therefore, since the additive 16 accommodated in the additive accommodating chamber S1 can be used sequentially from the one disposed below, the additive 16 contained in the water purification cartridge is submerged or watered as a whole. It is easy to take longer the usable period of time, and it becomes easy to suppress the fluctuation of the concentration of the additive smaller in the initial use and the late use of the purified water cartridge 6.

By changing the flow rate of the water in the additive storage chamber S1, the flow rate ratio of the water introduced from the 1st tap 7a and the water introduced from the 2nd tap 7b is changed, and thereby an additive concentration is changed. It is to let. Moreover, also in this embodiment, 23 A of substantially cylindrical cylindrical members with a bottom are attached so that rotation is possible so that case 7A may be covered from above, and the relative angle with respect to case 7A of 23 A of movable members will be adjusted. By changing, the area of the 1st water tap 7aA is changed.

However, in this embodiment, the 1st water tap 7aA is divided into the some water tap 70a, and the number of the water taps 70a shielded (opened) by the movable member 23A is set variable. It is supposed to be. Specifically, a plurality of slender tap slits 70a elongated in the circumferential direction are arranged in parallel on the circumferential wall 12a of the upper case 12A in a constant pitch up and down (four in this embodiment). It forms side by side, and the length of the water tap 70a becomes long as it goes from top to bottom. Therefore, as shown in FIG. 7, according to the rotational position of 23 A of movable members, the number of the guards 70a shielded changes. For example, in the state of FIG. 7A, all of the four water taps 70a are opened. In the state of FIG. 7B, the two taps 70a on the upper side are shielded and the lower side. The raceway 70a of (partially) is open.

Therefore, according to this embodiment, a user becomes easy to visually recognize the opening area of the 1st water tap 7aA as the number of the water tap 70a exposed to the outside, and also sets the additive concentration. The effect that it becomes easy to recognize is acquired.

Moreover, in this embodiment, the locking mechanism 24 which latches 23 A of movable members to the case 7A is provided in the position where the shielding water of the water tap 70a is switched. Specifically, while extending the groove 24a along the circumferential direction on the outer surface of the circumferential wall 12a of the upper case 12A, the protrusions are formed on the inner surface of the circumferential wall 23a of the movable member 23A. 24b) is provided, and the groove 24a is comprised so that the protrusion 24b may guide in a circumferential direction. And by providing the protrusion 24c which hold | maintains the protrusion 24b in a predetermined position in the groove 24a, and arrange | positioning this protrusion 24c suitably, 23 A of movable members are shielded of the water tap 70a. The number is fixed at a plurality of locations (four locations in the circumferential direction) in which the number is switched. The projections 24b are held at positions sandwiched between the end walls and the projections 24c at both ends of the grooves 24a, and at the intermediate positions of the grooves 24a, the projections 24b are sandwiched between the pair of projections 24c and 24c.

The figure which shows a state, (c) is a figure which shows the state in which the 1st water tool was opened.

The water purification cartridge 6B according to the present embodiment can be used by being mounted on the water purifier 1 in place of the water purification cartridge 6 according to the first embodiment.

Moreover, this water purification cartridge 6B also uses the movable member 23B for the opening area of the 1st water supply 7a formed in the case 7B similarly to the water purification cartridge 6 of the said 1st Embodiment. By changing the flow rate of water in the additive storage chamber S1, the ratio of the flow rate of water introduced from the first water tap 7a and water introduced from the second tap 7b is changed, whereby the additive concentration To change.

However, in this embodiment, the movable member 23B is attached to the case 7B so that the position of the up-down direction can be set variably, and the position of the up-down direction of the movable member 23B is variably set, and it is 1st. The opening height h (refer FIG. 9) of the water tool 7a is changed. Specifically, as shown in FIG. 8, the groove 25a provided in the circumferential wall 12a of the upper case 12B (case 7B), and the protrusion 25b provided in the inner surface of the movable member 23B. ), The height adjustment mechanism 25 is configured. The groove 25a is a vertical groove 25c extending downward from the upper end of the circumferential wall 12a and a plurality of horizontal grooves extending from the vertical groove 25c toward one side (left in FIG. 8) in the circumferential direction. Has 25d. The plurality of horizontal grooves 25d are arranged at a constant pitch (equal intervals) (five in this embodiment). Accordingly, the movable member 23B is lowered by causing the protrusion 25b along the horizontal groove 25d, and the movable member 23B is rotated in the circumferential direction to insert the protrusion 25b into any one horizontal groove 25d. By doing this, the height of the movable member 23B can be variably set to a plurality of stages (five stages in this embodiment). In addition, a protrusion 25e is formed inside the horizontal groove 25d, and the protrusion 25b is easily maintained at the innermost part of the horizontal groove 25d, and the protrusion 25b is exceeded to provide a feeling of click. It is suitable to generate.

With such a configuration, as shown in Figs. 9A to 9C, the opening height h of the first conduit 7a is variably set, whereby the flow rate of water in the additive storage chamber S1 is adjusted. The additive concentration can be changed by changing the flow rate ratio of the water introduced from the first water hole 7a and the water introduced from the second water hole 7b.

Moreover, in this embodiment, the height of the upper limit L of the immersion area | region Aw in the additive accommodating chamber S1 can be changed by the movable member 23B. In this embodiment, the lower end 23h of the center cylinder part 23f of the movable member 23B and the lower edge 23b of the lower side of the circumferential wall 23a become the same height. Thus, the annular recess 23i between the circumferential wall 23a of the movable member 23B and the central cylindrical portion 23f becomes an air reservoir as a whole, and the lower end 23h and the short edge 23b are formed. Since the position becomes the upper limit L of the submerged region Aw, as shown in FIGS. 10A to 10C, the additive 16 is immersed in water by varying the height of the movable member 23B. The additive concentration can be changed also by changing the amount to be made and by changing the amount of immersion. Therefore, in this embodiment, the actual additive concentration is determined by the height of this upper limit L and the opening area (opening height h) of the 1st water tap 7a.

And in the structure of this embodiment, as shown to FIG. 9 and FIG. 10 (a), while the 1st water tap 7a is blocked by the movable member 23B, the upper limit of the submerged area | region Aw is removed. It can be set to a position lower than the lower end (upper surface of the partition 14) of the additive accommodating chamber S1, and the additive concentration becomes almost zero without immersing the additive 16 in water.

As described above, in the present embodiment, the movable member 23B is attached to the case 7B in such a manner that the position in the vertical direction is variably set, and the position in the vertical direction of the movable member 23B is variably set. As a result, the opening height of the first water hole 7a was changed. Also with such a structure, the opening area of the 1st water tap 7a can be variably set, and, thereby, the flow volume of the water in the additive accommodation chamber S1 can be variably set. Therefore, the additive concentration can be variably set by changing the flow rate ratio of the water introduced from the first water hole 7a and the water introduced from the second water hole 7b. Moreover, since the amount of protrusion of the movable member 23B from the case 7B changes, there is an advantage that it is easy for the user to visually confirm the change of the opening area. In addition, in this embodiment, since the upper limit L of the submerged area | region Aw can be changed as the height position of the movable member 23B is changed, additive concentration can be variably set using this viscosity.

The water purification cartridge 6C according to the present modification is provided with a pressurizing mechanism 26 for pressing the additive 16 downward toward the submerged region Aw. The pressurizing mechanism 26 is elastically accommodated in the recessed part 18 of the top plate 12a and upper case 12B which are placed on the granular additive 16, and elastically pressurizing this top plate 26a downwards. The coil spring 26b as a pressurization mechanism is provided, and the additive 16 is crimped downward through the ceiling plate 26a by the compression reaction force of the coil spring 26b.

According to this structure, the additive 16 on the upper side can be moved more reliably downward by the pressurizing mechanism 26 as the additive 16 in the submerged region Aw is eluted. Compared with the case, the packing density of the additive 16 in the submerged region Aw can be increased. Moreover, it becomes possible to reduce the change of the density | concentration of the additive 16 in the submerged area | region Aw in the usage period of the purified water cartridge 6, and to suppress the fluctuation of additive concentration.

And the water purification cartridge 6B is changed by the movable member 27 in the up-down direction position of the lower wall 27a of the additive accommodating chamber S1. The communication area between the first water tap 7a and the additive storage chamber S1 is variably set, and the flow rate ratio of the water introduced from the first water tap 7a and the water introduced from the second tap 7b is variably set. Let's do it.

Specifically, the movable member 27 is closed from the lower wall 27a and the lower wall 27a having the slit 27c serving as an outlet while blocking the lower side of the additive storage chamber S1 in the same manner as the partition wall 14.

The first channel 7a is provided below the step portion of the circumferential wall 12a (below the upper limit L). In the leg part 27b, the slit 27d which overlaps with the 1st water tap 7a is formed. As a result, the first water passage 7a can be inserted through the slit 27d into the additive storage chamber S1. In addition, you may provide the 1st water tap 7a in the position without the leg part 27b.

In such a structure, by moving the movable member 27 up and down, the communication area of the 1st water tap 7a and the additive accommodation chamber S1 can be changed by changing the up-down position.

As described above, in the embodiment, the first water tap 7a and the additive accommodating chamber S1 are changed by the movable member 27 by changing the position of the lower wall 27a of the additive accommodating chamber S1 in the vertical direction. The communication area of variably was set, and the flow rate ratio of the water introduced from the 1st water tap 7a and the water introduced from the 2nd tap 7b was made variable. Therefore, since the flow rate ratio of the water introduced from the 1st water tap 7a and the water introduced from the 2nd tap 7b can be variably set by the movable member 27, the additive concentration can be easily set variably. .

The substantially rectangular notch 23cE which faces upward from the lower edge 23bE of the lower side is provided.

In such a configuration, when the position in the circumferential direction of the movable member 23E is changed, the area where the notches 23c and the second raceway 7b overlap with each other changes, and the opening width of the second raceway 7b and The opening area (width and area of the area facing the raw water chamber 4) can be variably set. That is, the flow rate ratio of the water introduced from the 1st tap 7a and the water introduced from the 2nd tap 7b can be variably set by the movable member 23E. Thereby, the additive concentration in the water (clean water) which passed the water purification cartridge 6 can be variably set.

As described above, in the present embodiment, the movable member 23E variably sets the opening area of the second raceway 7b. Therefore, by changing the position of the movable member 23E and varying the opening area of the second water tap 7b, the additive concentration can be easily set in the same manner as in the first embodiment.
