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.

(1st embodiment)

1 to 4 show a first embodiment of the present invention, FIG. 1 is a sectional view of the water purifier, FIG. 2 is a sectional view of the water purification cartridge, FIG. 3 is an exploded perspective view of the water purification cartridge, and FIG. 4 is a water purification cartridge. 4A is a view showing a state in which the water tap is opened by the movable shield member, and FIG. 4B is a view showing a state in which the water tap is half closed.

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 pot type water purifier. In the tub of the substantially bottomed cylindrical port case 2, a tubular partitioned body 3 having a substantially bottom is accommodated, and the inside of the casing of the port case 2 is formed by the bulkhead 3. It is divided into the raw water chamber 4 which forms about half of the upper side, 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 is formed which is recessed downward. The substantially cylindrical clean water cartridge 6 is inserted into this recessed part 3b from the top to the inside, and is attached. 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 recess 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 water tap 7a and the additional water tap 7b face the raw water chamber 4. The additional waterway 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 drain port 7c formed in the case 7 in this lower end part 6b is the water purification chamber. It is supposed to face (5). The raw water in the raw water chamber 4 is introduced into the purified water cartridge 6 from the water tap 7a and the additional water tap 7b, and is discharged from the drain 7c into the water purification chamber 5 at least after it is purified.

Above the raw water chamber 4, the ceiling wall 8 in which the water supply port 8a was formed is arrange | positioned. The water supply port 8a is closed by the upwardly open lid 9 provided on the ceiling wall 8 so as to be rotatable. Raw water is supplied into the raw water chamber 4 via the water supply port 8a in the state which opened the lid 9 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 port case 2, and the port case 2 or the ceiling wall 8 is formed. ), A water spout 10a is formed at a position to become an upper end of the passage 10. In the present embodiment, the pot case 2 is tilted so that the water inlet 10a is downward (in FIG. 1, the pot case 2 is tilted in a clockwise rotation direction to fall), so that the pot case 2 is in the water purification chamber 5. The stored purified water is discharged from the pouring hole 10a via the passage 10. In addition, in this embodiment, the spout 10a is blocked by the up-opening lid 11 supported rotatably by the port case 2 or the ceiling wall 8 so that opening and closing is possible. In this case, when the pot 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 use, and an upper edge of the lower case 13 and the lower case 13 of the upper case 12. I) are combined to each other to show an approximately cylindrical shape. 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 spaces largely in the up-down direction (axial direction) by the partition 14 and the seats 15 disposed below the partition 14 at intervals. Among them, an additive accommodating chamber S1 in which the uppermost part accommodates the additive 16, a purifying chamber S2 in which the lowermost part purifies water, and an intermediate part S3 are provided.

The additive storage chamber S1 is formed surrounded by the upper case 12 and the partition wall 14. The upper case 12 has a water purification cartridge 6 from the main wall 12a which forms the upper part of the main wall of the case 7, the ceiling wall 12b which forms the ceiling wall of the case 7, and the center part of the ceiling wall 12b. It has the inner cylinder 12c extended below along the central axis Ax of approximately. And the partition 14 is provided in this upper case 12 so that the lower part in the cylinder may be blocked. That is, in this embodiment, the cross section enclosed by the circumferential wall 12a, the ceiling wall 12b, the inner cylinder 12c, and the partition 14 in the cylinder of the upper case 12 is a substantially annular space, and the additive storage chamber S1. ) Is formed. In this additive storage chamber S1, additive 16, such as granular calcium, whose diameter is about several millimeters, is accommodated, for example.

As shown in FIG. 3, FIG. 4, etc., the principal wall 12a is formed with the substantially rectangular water tap 7a. The water-permeable mesh 17 extends to the water tool 7a by insert molding, and the flow of the additive 16 from the water tool 7a is suppressed. In addition, the inner cylinder 12c is formed with a slit-shaped cutout portion 12d extending upward from the lower end thereof. 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 flows out from the notch 12d. In addition, in this embodiment, the axial position of the upper edge 12e of the notch 12d and the axial position of the upper edge 12f of the raceway 7a are made 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, The inner part 12c protrudes upwards in the center part of this protrusion part 14b. The cylinder portion 14c through which the insertion is made is formed. In the bottom wall portion 14a, a plurality of slits 14d extending radially from the central axis Ax of the water purification cartridge 6 are formed as drains from the additive storage chamber S1. The width of this slit 14d is set smaller than the particle diameter of the additive 16, and the flow of the additive 16 from the slit 14d is suppressed by this.

In the additive storage chamber S1 having the above-described configuration, the additive 16 is eluted to the raw water introduced into the additive storage chamber S1 from the raw water chamber 4 via the water tap 7a, and the additive is added. Water flows out from the additive storage chamber S1 to the intermediate chamber S3 via the slit 14d of the partition 14.

Here, in this embodiment, the air chamber Aa which traps air in the upper part of the additive storage chamber S1 is formed, and this is the inside of the air chamber 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, since the recessed part 18 which consists of the circumferential wall 12a, the ceiling wall 12b, and the inner cylinder 12c only opens downward, there is no way for air to escape upwards, and therefore, Even if water penetrates into the additive storage chamber S1, and the upper portion 6a of the water purification cartridge 6 is completely locked (i.e., submerged) in the water stored in the raw water chamber 4, the concave portion ( The air is accumulated in 18), and the blood of the additive 16 in the air chamber Aa can be prevented. In the present embodiment, the positions of the top edges 12e and 12f of the cutout portion 12d and the raceway 7a are usually the upper limit L of the submerged region Aw, and are below the upper limit L. The additive 16 located 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 submerged in water and eluted, the additive 16 located above drops downward by gravity to automatically replenish the submerged region Aw. As a result, the additive 16 contained in the additive storage chamber S1 can be used sequentially from the one disposed below, so that the additive 16 is submerged or avoided as a whole. It is not only easy to hold the usable period of time longer, but also it is easier to suppress the difference in concentration of the additive in the initial use and the late use of the purified water cartridge 6.

In the lower part of the circumferential wall 12a of the upper case 12 constituting the circumferential wall of the intermediate chamber S3, as shown in Figs. Formed. As a result, raw water is introduced into the intermediate chamber S3 from the raw water chamber 4 via the additional water outlet 7b and water is added to the additive through the slit 14d from the additive storage chamber S1. These water is introduced into the adsorption treatment chamber S21 of the purification chamber S2 disposed below the intermediate chamber S3. In other words, in the present embodiment, the raw water introduced into the intermediate chamber S3 from the additional tap 7b bypasses the additive containing chamber S1. Thus, by dividing the water flowing in 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) The flow rate of the water to bypass can be set independently, thereby making it easy to improve the adjustment accuracy of the additive concentration.

In addition, in this embodiment, the additional channel 7b is arrange | positioned below the channel 7a. For this reason, the head difference caused by the difference between the heights of the ditches 7a and the additional ditches 7b and at the position close to the bottom wall 3a of the partition body 3 at the beginning of the water supply to the raw water compartment 4 are located. Due to the dynamic pressure of water reaching the additional water tap 7b, the water is more likely to enter the additional tap 7b as compared to the water tap 7a. In this way, in particular, the flow rate of the water in the tap 7a can be relatively small at the beginning of water supply to the raw water chamber 4, so that the flow rate of the water in the additive storage chamber S1 can be easily adjusted.

Purification chamber S2 arrange | positioned under intermediate chamber S3 is partitioned radially by the substantially cylindrical cylinder 19 arrange | positioned at the position along the central axis Ax of the water purification cartridge 6, In 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 powdery activated carbon etc.) 20 was accommodated, and the inside of the cylinder of the cylinder 19 is a filter medium (for example, , A hollow fiber membrane curved in an inverted "U" shape, etc.) 21 is housed in a filtration processing chamber S22. In such a configuration, the water introduced from the intermediate chamber S3 is discharged from the drain port 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 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 is centered on the water purification cartridge 6 by this. It is provided upright along the axis Ax.

The adsorption process chamber S21 is surrounded by the circumferential wall 13c, the cylinder 19, the bottom wall 13a, and the sheet 15 of the lower case 13 forming the lower part of the circumferential wall of the case 7, and has a substantially annular cross section. It is formed in a cylindrical shape. 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 19, and the outer edge portion 15a is sandwiched between the upper case 12 and the lower case 13 so that the case 7 It is fixed to. On the other hand, the inner edge part 15b allows water to be introduced into the adsorption treatment chamber S21 from the intermediate chamber S3 via the gap between the inner edge part 15b and the cylinder 19 as a free end. In addition, the sheet 15 may be made of a water-permeable material so as to permeate water. In addition, in this embodiment, the cap 22 is attached to the upper end of the cylinder 19, and the inner edge part 15b of the sheet | seat 15 is provided by the flange part 22a which extends outward from this cap 22 in diameter. ) Is prevented from overturning above the flange portion 22a. With such a configuration, even when the water purifying cartridge 6 is inclined or vertically reversed in a state where the water purifying cartridge 6 is separated from the water purifier 1, since the sheet 15 is caught by the flange portion 22a, 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. The water removed by adsorbing impurities to the adsorbent 20 in the adsorption treatment chamber S21 is introduced into the filtration treatment chamber S22 via 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 reverse "U" shape. The water that has permeated through the membrane wall of the hollow fiber membrane from the filtration chamber S22 and flows out into the lower end portion of the filtration chamber S22 through the membrane is discharged from the drain port 7c to the water purification chamber 5. Spills. 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 filling the gap with an adhesive (not shown) below the communicating port 19a, and the hollow fiber membrane is filtered from the inside of the filtration processing chamber S22 by the adhesive. Direct outflow is prevented without passing through the membrane.

The inventors earnestly studied the water purification cartridge 6 having the above-described configuration, and it was found that the additive concentration of the water was changed in accordance with the flow rate of the water flowing in the additive storage chamber S1. As an example, when a granular calcium agent is used as the additive 16, the agitation effect due to water flow increases as the flow rate of water flowing in the additive accommodating chamber S1 increases, and water in the additive accommodating chamber S1 is increased. The amount of the additive mixed in the water increases, and as a result, the additive concentration of the water after the water that has passed through the additive containing chamber S1 and the water introduced into the water purification cartridge 6 from the additional tap 7b joins, It is found that the additive concentration of the water discharged from the purified water cartridge 6 increases. Therefore, in this embodiment, the movable shielding member 23 which variably sets the opening area of the raceway 7a is provided in the case 7, and the additive accommodating chamber S1 is adjusted by the position adjustment of the movable shielding member 23. As shown in FIG. The flow rate of the water flowing in the inside of the flask was changed, whereby the concentration of the additive in the water (purified water) having passed through the purified water cartridge 6 was changed.

In this embodiment, as shown in FIGS. 2-4, the substantially movable cylindrical shielding member 23 with a bottom which covers the outer periphery of the upper case 12 from upper direction along the circumferential direction of the upper case 12 is shown. It is installed rotatably. The circumferential wall 23a of the movable shield member 23 covers the circumferential wall 12a of the upper case 12 with a slight gap, and the circumferential wall 23a faces upward from the lower end circumference 23b as an opening portion. An approximately rectangular cutout 23c is provided.

On the outer surface of the circumferential wall 12a of the upper case 12, a plurality of convex lines 12g along the circumferential direction (three in the present embodiment) are provided substantially parallel to each other at regular intervals above and below, while the movable shield member 23 d of protrusions are provided in the inner surface of the circumferential wall 23a of 23, and the protrusion 23d is axially convex 12g in the state which bonded the movable shielding member 23 to the upper case 12. As shown in FIG. The protrusion 23d is guided in the circumferential direction by the convex line 12g. In addition, as shown in FIG. 3, the convex line 12g is provided with the notch 12h which allows relative movement of the protrusion 23d in the axial direction. Thus, the upper case 12 and the movable shielding member 23 are brought close to each other in the axial direction until they collide with each other in the state where the protrusions 23d and the cutout portions 12h are aligned with each other, and then they are placed relative to each other in the circumferential direction. By rotating, the protrusion 23d is accommodated between the convex lines 12g, and the movable shielding member 23 can be stuck to the upper case 12 (case 7), and the movable shielding member 23 is upper part. It can be rotated along the circumferential direction of the case 12.

In this structure, as shown in FIG. 4, when the position of the circumferential direction of the movable shield member 23 is changed, the area which the notch 23c and the water tap 7a overlap will change, and the water tap 7a will be changed. The opening width w and the opening area (width and area of the area facing the raw water chamber 4) can be variably set.

4A shows a state in which the entire area of the waterway 7a is opened. In this state, since the flow volume of the water which flows into the additive accommodation chamber S1 from the water supply port 7a is comparatively large, the density | concentration of the additive which elutes to water in the additive accommodation chamber S1 becomes high.

In FIG. 4B, approximately half of the water tap 7a is blocked by the circumferential wall 23a of the movable shielding member 23 and approximately half is opened. In this state, compared with the case of FIG. 4A, the flow volume of water in the additive accommodating chamber S1 decreases, and the density | concentration of the additive eluting to water in the additive accommodating chamber S1 becomes low by that much.

Thus, according to the purified water cartridge 6 which concerns on this embodiment, the additive 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 shielding member 23. As shown in FIG. The concentration can be changed.

In addition, if air accumulates unexpectedly in each part of the purified water cartridge 6, especially in the intermediate chamber S3, or between the sheet 15 and the adsorbent 20, the gravity of the water and the buoyancy of the air are balanced and the water flow path is air. Because of clogging, the desired flow rate may not be obtained, it may take a long time to obtain a purified water, or the desired additive concentration may not be obtained. Therefore, in this embodiment, the air bleeding passage is formed substantially along the central axis Ax of the purified water cartridge 6.

Specifically, a substantially cylindrical central cylinder portion 23f that extends downward and enters into the cylinder of the inner cylinder 12c is formed at the center portion of the ceiling wall 23e of the movable shield member 23, and the central cylinder portion 23f is provided. A through hole 23g penetrating through the ceiling wall 23e is formed in the inner side (upper side) of the inner wall. This through hole 23g becomes the air bleed hole of the clean water cartridge 6.

The cap 22 fitted to the upper end of the cylinder 19 has a conical portion 22b that is thinned upward and a cylindrical portion 22c extending upward from the top of the cone portion 22b. The tip end of the cylindrical portion 22c is extended to the vicinity of the lower end of the central cylindrical portion 23f. Thereby, the air in filtration process chamber S22 is discharged | emitted from the through hole 23g through the inside of the cylinder part of the cone part 22b, the cylinder part 22c, and the center cylinder part 23f.

Air in the adsorption treatment chamber S21 and the intermediate chamber S3 moves along the protrusion 14b of the partition 14 to the central axis Ax side of the water purification cartridge 6, and passes through the cutout 12d to the inner cylinder. It enters into the cylinder of 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.

23 g of through-holes through the inside of the cylinder of the inner cylinder 12c and the inside of the cylinder of the center cylinder 23f from the notch 12d, except that air in the additive storage chamber S1 is accumulated in the air chamber Aa. Is discharged from.

As described above, in the present embodiment, the case 7 is provided with a raceway 7a for introducing water into the additive storage chamber S1, and the opening area of the raceway 7a in the case 7. The movable shielding member 23 which sets this variable is installed. Thereby, compared with the structure which provides a valve etc. and changes a flow volume, the structure which can set variable additive concentration can be obtained as a comparatively simple structure. In addition, when calcium etc. are used as an additive, the hardness of water can be variably set.

In addition, in this embodiment, the water hole 7a is formed in the circumferential wall 12a of the upper case 12 as the outer wall of the case 7, and the circumferential wall of the movable shield member 23 which covers the outer side of the circumferential wall 12a ( 23a) was made to block the water tool 7a. Thereby, it becomes easy for a user to operate the movable shield member 23 so that the movable shield member 23 is arrange | positioned so that the outer side of the case 7 may be covered.

In addition, in this embodiment, at least the upper part of the case 7 is formed in substantially cylindrical shape, and the water flow tool 7a is formed in the circumferential wall 12a, and the movable shield member 23 is moved upwards of the said case 7. It formed in the cylindrical shape with the bottom covered from the inside, and the circumference | surroundings of the case 7 were made to block the water flow opening 7a by the circumferential wall 23a of the movable shield member 23. As shown in FIG. As a result, the movable shielding member 23 can be obtained in a relatively simple configuration, and the movable shielding member 23 can be more stably supported on the case 7. In addition, the opening area of the raceway 7a can be changed by a relatively simple operation of moving the movable shielding member 23 relative to the case 7 (moving in the lateral direction) to change the additive concentration. have. In addition, like the present embodiment, when the water purification cartridge 6 is inserted into the port case 2 of the water purifier 1 from above, the movable shield member is moved from above while being mounted in the port case 2. It is convenient to be able to operate (23).

In addition, in this embodiment, the additional water supply 7b which introduces water into the purification chamber S2 by bypassing the additive storage chamber S1 in the case 7 was formed. Thereby, by classifying 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 water can be set independently, thereby making it easy to increase the adjustment accuracy of the additive concentration.

In addition, in this embodiment, the raceway 7a was arrange | positioned above the additional raceway 7b. For this reason, the head difference caused by the difference between the heights of the ditches 7a and the additional ditches 7b, and at the position close to the bottom wall 3a of the bulkhead 3 at the beginning of the water supply to the raw water chamber 4 By the dynamic pressure of the water reaching the additional water tap 7b, the water is more likely to enter the additional tap 7b as compared with the water tap 7a. Therefore, especially in the beginning when water is supplied to the raw water chamber 4, the flow volume of water in the tap 7a can be made relatively small, and it becomes easy to adjust the flow volume of 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 shield member 23 which changes the opening area of the water tap 7a in the upper part of the water purification cartridge 6. As shown in FIG. Therefore, when the water purification cartridge 6 is inserted into and mounted in the port case 2 of the water purifier 1 from above, as in the present embodiment, the immersion height is movable from above while being mounted in the port case 2. It becomes easy to operate the shielding member 23, and it is convenient.

In addition, in this embodiment, since the additive accommodation chamber S1 was arrange | positioned above the additional power tool 7b, after the water level of the raw water chamber 4 becomes lower than the lower end of the additive storage chamber S1, additional frequency is added. Water flows into the purified water cartridge 6 only from the sphere 7b, and the intermediate chamber S3 and its downstream side are made of water that does not pass through the additive storage chamber S1 and does not contain the additive 16. Discharge of the additive 16 can be promoted in the phosphorus purification chamber S2 to suppress the additive 16 from remaining. Thereby, at the next use, it becomes possible to suppress that the additive concentration becomes higher than the set value by the remaining additive 16, so that the desired additive concentration is easily obtained.

In the present embodiment, the air gutter portion Aa is formed in the upper portion of the additive storage chamber S1, and the water tap is in the submerged region Aw in which the additive 16 is lower than the air grime portion Aa.

In such a configuration, the additive 16 in the air chamber Aa can be kept in a state of not being submerged or avoided. When the additive 16 in the submerged area Aw is immersed in water and eluted, the additive 16 located above it falls down by gravity to automatically replenish the submerged area Aw. . Since the additive 16 accommodated in the additive storage chamber S1 can be used sequentially from the one arranged below, the additive 16 is submerged in comparison with the structure in which the additive contained in the water purification cartridge is flooded or avoided as a whole. It is not only easy to hold the usable period of time longer, but also makes it easier to reduce the variation in the concentration of the additive 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 by the height of the immersion area | region Aw, and by this, the maximum value of an additive concentration can be set. That is, it can suppress that the additive 16 melt | dissolves in water more than necessary.

As a result, the opening height of the raceway 7a was changed. Also with such a structure, the opening area of the water tap 7a can be variably set, and by this, the flow volume of the water in the additive storage chamber S1 can be variably set, and the additive concentration can be variably set. Moreover, since the protrusion amount from the case 7B of the movable shield member 23B changes, there is an advantage that the user becomes easy to visually recognize 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 with changing the height position of the movable shield member 23B, an additive concentration can be variably set using this viscosity. .
