The above-mentioned wire-and-groove portion is provided so that the lowermost portion of the mineral-adding portion 5 portion 51 forming the water purifier cartridge 更 is opened at the center of the bottom portion of the concave portion 62, and the segment of the adsorption container 7 Part 8 13 200927260 The outer side 'on the entire circumference - the body forms the entire circumference of the directional direction and the part 26, so that the convex portion 26 is attached to the 二2 2 _ circumference, so that the suction 1 = I circumference wall and The mounting recessed portion 62 is in close contact. Further, in the groove portion of the outer peripheral surface of the segment portion 8, the O-ring 27 is lost, and the ring portion 27 is brought into close contact with the mounting recess portion 62. Purified water is obtained by using the water purifier 50 of the water purifier having the above configuration in the following procedure. Gp, first, the baffle 58 of the crotch portion 56 is turned upward to open the water supply port 57, and the raw water such as tap water is supplied into the f water storage portion 51 through the water supply port 57. The supplied raw water is temporarily stored in the raw water product unit 51 and introduced into the water purifier filter 1 through the plurality of water guiding ports 17 of the upper cover 16, and is moved to the adsorption water purification unit 2 and the filtered water purification unit 3 that communicates therewith. The raw material addition unit 5 is filled with raw water. Here, the main water passing through the water purifier cartridge 1 due to its own weight and flowing down to the main flow path of the purified water storage unit 52 is as follows: • The raw water flows down from the water guiding port 17 and temporarily accumulates in the adsorbing purified water unit 2, and is adsorbed by the adsorbent. After the action is purified, it is introduced into the filtered water purification unit 3 through the communication hole 14 that communicates with the lower end portion of the adsorption water purification unit 2, and further filtered by the filtration action of the filter body filled in the filtration water purification unit 3. After being cleaned as described above, the component is sequentially flowed down to the lower water purification reservoir 52 by forming an open pouring port 9 at the lowermost end of the water purifier cartridge 1. Purification is carried out by adsorption and filtration during the passage through the main flow path. 200927260 Then, in the main flow path (refer to the white hollow arrow in FIG. 2), the mineral-adding portion 5 dissolves the material-expanding component of the mineral agent into the raw water filled in the mineral-adding portion 5. The obtained high-expansion material water 'is sequentially supplied through the mineral elution holes 20. That is, the raw water passing through the water purifier filter element 1 is water which is subjected to water purification treatment by adsorption and filtration and to which a mineral component is added. However, when all of the water purifier filter cartridge is filled with raw water for purifying water, if bubbles are trapped in the adsorbed purified water portion 2 or in the filtered purified water portion 3, the water passing performance is lowered, and the water quality of the purified water is unstable. . However, according to the water purifier cartridge 1 having the above configuration, the air bubbles generated in the adsorbed water purification unit 2 are floated into the mineral addition portion 5 above the mineral elution hole 20 or the air introduction hole 22, and then in the minerals. The air bubbles generated in the adding portion 5 are discharged from the exhaust port 23 to the raw water reservoir portion 51 side. In addition, the air bubbles generated in the filtered water purification unit 3 float up to the upper side of the filter container 6, and are then transported to the filter unit side exhaust port 18 through the deaeration passage 19 connected to the filter container 6, and discharged to the raw water reservoir. Part 51 side. Further, even if the raw water is accumulated in the raw water reservoir 51 above the filter portion side exhaust port 18 of the water purifier cartridge i, the air accumulated at the upper end portion of the deaeration passage 19 prevents the inflow of the raw water. Therefore, the raw water in the raw water reservoir 51 can be prevented from directly flowing into the filtered water purification unit 3 through the deaeration passage 19'. The characteristic portion of the water purifier 50 having the water purifier cartridge 1 of this example will be described in more detail below. As described above, the water purifier cartridge 1 of the present embodiment includes the purified water portion 4 composed of the adsorbed purified water portion 2 for purifying the raw water and the filtered purified water portion 15 200927260 3 , and further the raw water passing through the purified water portion 4 Since the mineral-added portion 5 in which the mineral is formed into a knives is added, the raw water in the raw water reservoir portion μ can be purified, and after the mineral component is added, the water can be discharged into the purified water reservoir 52. Further, the women's concave portion 62 is provided so as to be recessed from the lower portion 51a of the raw water reservoir portion 1 to the lower portion 51a, and when the water purifier filter cartridge is fitted into the recessed portion 62, due to the water purifier The clean water portion 4 formed in the lower half of the filter cartridge is located in the mounting recess portion 62, and the obstruction substance addition portion 5 formed in the upper half of the water purifier cartridge i protrudes toward the raw water reservoir 51 and is located In the southerness position of the lowermost line 51a of the raw water reservoir 51 of the water purifier 50, which is equal to or higher than the height line (see ", line L in FIG. 2), it is assumed that the generated purified water is accumulated in the purified water reservoir 52. In the water-filled water level of the water surface, the mineral agent in the mineral-adding portion 5 is not immersed in the water. Therefore, it is possible to prevent the mineral component of the mineral agent in the water-storage portion 52 from being continuously dissolved. In the case where the water is continuously supplied to the raw water reservoir 51, the raw water in the raw water reservoir 51 is not introduced into the water purifier filter 1 when the water is continuously supplied to the raw water reservoir 51. However, it remains in the original water reservoir 51. In addition, 'in this case In the water purifier cartridge 1, a mineral addition unit 5 is provided at a position spaced apart from the main flow path, and the main flow path is an adsorption water purification unit in which the raw water starts from the raw water storage unit 51 and passes through the water purifier filter cartridge. 2 and the filtered water purification unit 3, which flows down from the discharge port 9 to the flow path in the lower water storage unit 52. The branch flow path 35 is connected to the intermediate portion of the main flow path and the mineral addition unit 5. The mineral elution hole 2〇, 200927260 = a structure in which the raw water flowing in the main flow path and the water in the impurity addition unit 5 are gradually merged in an appropriate amount, so that a stable amount of the mineral component can be continuously supplied after the water supply is started.

From the data, it can be seen that when the mineral agent is filled into the main channel, the result is that the mineral (four) component is not dissolved in the initial stage of the water flow, and the mineral component is dissolved as the water flow rate increases. There are fewer big ones. On the other hand, in the case where the mineral f addition portion 5 that communicates via the branch flow path 35 is filled with minerals, the mineral component is continuously supplied after the water is passed. Here, since the mineral water f-dissolving hole 2 贯穿 which is formed in the partition wall 4 分隔 which is separated from the water purification unit 4 and the mineral addition unit 5 in the main flow path is used as the branch flow path 35 described above, it is possible to be compact. The structure having a high degree of freedom in design is formed to form the branch flow path 35. That is, since the mineral elution hole 2G constituting the branch flow path % is only singularly formed by providing a slit-like hole in the outer peripheral wall of the mineral container 15, no special member is required, and The design freedom of the shape is also high. Therefore, for example, by changing the number of the mineral elution holes 2G or the shape of the slit, the present example can be simply changed to another design in which the amount of dissolution of the mineral component is large (or small). Further, the upper end portion 4 of the partition wall 4 that is located above the mineral elution hole 2〇 is different from the mineral material dissolution hole 20 that connects the purified water portion 4 in the main flow path and the mineral f addition portion 17 200927260 5 The air introduction hole 22 is formed, and the mineral dissolution hole 20 is formed at the lower end portion of the partition wall 4''. As a result, the original fire accumulated. All of the raw water in the 51 passes through the water purifier cartridge 1 and is supplied to the purified water product. At the final stage of the portion 52, the strontium mineral water in the mineral addition portion 5 can be prevented from flowing down to the purified water portion 4 at once. . In the case where the air introduction hole 22 is not provided, if the water level in the original water storage unit 51 is lowered in the state in which the raw water is filled in the water purification unit 4 and the mineral addition unit 5, first, When the water level falls to the extent of the lowermost water guiding port 17 of the two water guiding ports 17 which are arranged side by side in the up-and-down direction on the peripheral wall of the upper cover 16 in the raw water reservoir 51, it is inside the water purifier filter & The water level in the side of the water purification portion 4 separated by the partition wall 4G starts to decrease, and then the water level on the side of the water purification portion 4 gradually decreases from the upper end of the partition wall 40, and descends to the mineral dissolution hole 20 at the lower end of the partition wall 40. & When the time is set, the water level of the high-mineral water filled in the substance addition unit 5 is turned on, and the water content of the bismuth mineral water is concentrated in the final stage and flows down to the clean water ❹ 4 = clean water storage unit 52. Therefore, after passing through the water purifier cartridge i and then discharged into the purified water on the side of the purified water reservoir 52, only the last small amount of purified water contains a very high concentration of mineral components. In the case where the air introduction hole 22 is provided, the water level in the water purification unit 4 can be started to decrease (that is, the raw water filled in the purified water unit 4 is concentrated on the purified water storage unit). The time at the side) and the timing at which the water level in the mineral addition unit 5 starts to decrease (that is, the time at which the high-mineral water in the mineral addition & portion 5 concentrates on the purified water portion 4 side) is substantially the same. In the case where the air introduction hole 22 is provided, when the water level in the raw water reservoir 51 is lowered in the state where the water purification unit 4 and the mineral addition unit 5 are filled with the raw water in the 18 200927260, the water level drops to the upper cover 16 . The water level in the water purification unit 4 partitioned by the partition wall 40 starts to decrease at the same time as the lowest water guide port 17 of the peripheral wall, and is filled in the raw water reservoir 5 through the air introduction hole 22 at the upper end. The water level of high mineral water also began to decline. With this configuration, the high-mineral water filled in the raw water reservoir 5 can be prevented from flowing to the water purification unit 4 as soon as possible, and only the last small amount of purified water in the purified water discharged from the purified water storage unit 52 can be prevented. Very high concentration of mineral tannins. Further, the water purifier cartridge 1 of the present example is disposed at the top of the filter cartridge casing 30 constituting the outer casing of the water purifier cartridge i (i.e., the upper portion of the mineral addition portion 5 formed in the upper half of the water purifier cartridge i). There is an exhaust port 23 that discharges the air bubbles generated in the mineral addition unit 5 to the outside of the filter element. Therefore, the air bubbles generated in the mineral addition unit 5 can pass through the lower adsorption water purification unit 2 . Alternatively, the purified water portion 3 is filtered and discharged to the outside. Further, since a plurality of protrusions 25 are provided extending downward from the periphery of the exhaust port 23, it is possible to prevent the mineral agent filled in the mineral addition unit 5 from clogging the exhaust ports 2, although the present invention has been The preferred embodiment is disclosed above, but it is not intended to limit the invention to those skilled in the art, and the invention may be modified and modified without departing from the spirit and scope of the invention. Depending on the system, please refer to the special fiber.
