The valve 4 adjusts the amount of water passing through each of the water channels 21 and 22 by changing the opening area (opening degree) communicating with the bypass water channel 21 and the bypass water channel 22.

  As shown in FIG. 2, the mineral cartridge 3 has a cartridge case having an inlet 5 for raw water at one end (lower end in FIG. 2) and an outlet 6 for mineral water at the other end (upper end in FIG. 2). 30, a mineral agent storage portion 40 disposed between the inlet 5 and the outlet 6 in the cartridge case 30, and a mineral agent 7 stored in the mineral agent storage portion 40. The raw water that has flowed into the cartridge case 30 from the inlet 5 passes through the mineral agent 7 in the mineral agent storage section 40 and is added with mineral components, so that the generated mineral water flows out from the outlet 6. It has become.

  The cartridge case 30 includes a lower case 31 and an upper case 32, and is formed in a substantially cylindrical shape by connecting the lower case 31 and the upper case 32.

  The lower case 31 is formed in a cylindrical shape with a bottom wall 31a provided at the lower end, and the above-described inflow port 5 is formed at the center of the bottom wall 31a. The upper case 32 is formed in a cylindrical shape with a top wall 32a provided at the upper end, and the above-described outlet 6 is formed at the center of the top wall 32a. The lower case 31 and the upper case 32 are fixed by screwing the inner periphery of the lower end portion of the upper case 32 to the outer periphery of the upper end portion of the lower case 31. At this time, the lower case 31 and the upper case 32 are fixed with a liquid-tight structure by sealing the gap between the lower case 31 and the upper case 32 with the O-ring 61.

  Moreover, in this embodiment, what mixed and solidified one type or multiple types, such as calcium, sodium, magnesium, etc. is used as the mineral agent 7, This mineral agent 7 has the bottom wall 41 by the lower end. It is stored in a closed cylindrical mineral agent storage section 40.

  The mineral agent storage unit 40 includes a bottom wall 41, a cylindrical side wall 43 that rises from the peripheral edge of the bottom wall 41, and a top wall 47 that closes the upper opening of the cylindrical side wall 43. The provided rib is mounted on the upper end of the lower case 31 and the top wall 47 is fitted into the upper case 32 to be fixed in the cartridge case 30. A gap between the outer periphery of the top wall 47 and the inner periphery of the upper case 32 is sealed by an O-ring 62 provided on the top wall 47.

  Further, a center pipe 44 disposed on the central axis with a space therebetween is disposed inside the cylindrical side wall 43. The mineral agent 7 is filled in the space between the cylindrical side wall 43 and the center pipe 44.

  Moreover, in this embodiment, the lower case 31, the mineral agent storage part 40, and the center pipe 44 are arrange | positioned concentrically.

  The cylindrical side wall 43 has an opening at the lower end 43b, and a mesh (water inflow portion) 45 that allows water to pass through but prevents the mineral agent 7 from passing through is attached to the opening 43c. Then, raw water is taken into the mineral agent 7 through the mesh 45. Similarly to the cylindrical side wall 43, the lower end 44b of the center pipe 44 is also open, and a mesh 46 that allows water to pass but prevents the mineral agent 7 from passing through is attached to the opening 44e. The water that has passed through the mineral agent 7 passes through the mesh 46 of the center pipe 44 and flows into the central cavity 44a.

  The lower end portion 44 b of the center pipe 44 is closely fitted to a fitting portion 41 a projecting downward from the center portion of the bottom wall 41, and the upper end 44 c of the center pipe 44 is at the center portion of the top wall 47. A fitting portion 47a projecting downward is closely fitted via an O-ring 63. In addition, a communication port 47 b that connects the central cavity 44 a of the center pipe 44 to the outlet 6 of the upper case 32 is formed at the center of the fitting portion 47 a.

  Further, between the inner surface of the side wall 31 d of the lower case 31 and the outer surface of the cylindrical side wall 43, the raw water flowing in from the inflow port 5 flows upward from below, and the raw water passes through the mesh 45 to form the cylindrical side wall. A raw water passage 5 a for supplying to 43 is provided. In the present embodiment, the raw water passage 5 a is provided concentrically on the outer periphery of the mesh 45.

  The inflow port 5 is provided with a cover portion 51 that covers the vicinity of the downstream side of the inflow port 5, and a plurality of openings 52 are formed around the cover portion 51. And the raw | natural water which flowed in from the inflow port 5 passes through the opening part 52, is distributed in the direction along the bottom wall 41 of the mineral agent storage part 40, and flows into the raw | natural water channel | path 5a. Therefore, the flow path of the raw water from the inflow port 5 to the raw water passage 5a is a bent path that bends over the cylindrical side wall 43 of the mineral agent storage unit 40 that takes in the raw water from the bottom wall 41 of the mineral agent storage unit 40. It is formed and communicates with the raw water passage 5a. Further, a fitting hole 53 is formed on the upper surface of the covering portion 51 of the inflow port 5, and by fitting the fitting portion 41 a of the bottom wall 41 into the fitting hole 53, The lower part is fixed in the cartridge case 30.

  With this configuration, the raw water flowing into the lower case 31 from the inlet 5 of the mineral cartridge 3 flows through the raw water passage 5a and is taken into the mineral agent storage unit 40 from the mesh 45 of the cylindrical side wall 43, Mineral components are added while passing through the mineral agent 7. Then, the water to which the mineral component is added passes through the center pipe 44 and is supplied to the central cavity 44 a, and the mineral water in the central cavity 44 a flows out from the outlet 6 through the communication port 47 b of the top wall 47. .

  Next, the operation of this configuration will be described.

  First, the raw water flowing into the bypass water passage 21 from the branch part D through the water passage 2 is mixed with the raw water flowing through the bypass water passage 22 via the valve 4 after passing through the mineral cartridge 3. At this time, when the raw water in the bypass channel 21 passes through the mineral cartridge 3, the mineral component eluted from the mineral agent 7 is contained, and when passing through the valve 4, mineral water having a substantially constant concentration is formed. The mineral water is diluted by mixing with raw water passing through the bypass water channel 22.

  At this time, in the present embodiment, the mineral concentration of mineral water supplied via a faucet or the like can be changed according to the opening degree of the valve 4.

  For example, if the opening area (opening degree) communicating with the bypass water channel 21 of the valve 4 is reduced, the ratio of mineral water to the raw water flowing through the bypass water channel 22 is reduced, and the mineral water supplied through a faucet or the like is reduced. Mineral concentration can be lowered. On the other hand, if the opening area (opening degree) communicating with the bypass water channel 21 of the valve 4 is increased, the ratio of mineral water to the raw water flowing through the bypass water channel 22 increases, and the mineral water supplied through a faucet or the like. Mineral concentration can be increased. Note that the opening degree of the valve 4 communicating with the bypass water channel 22 is increased by decreasing the opening degree of the valve 4 communicating with the bypass water channel 21, and the opening degree of the valve 4 communicating with the bypass water channel 21 is increased. The opening degree communicating with 22 is reduced.

  As described above, in the present embodiment, mineral water having a desired concentration can be obtained by changing the opening degree of the valve 4. In addition, the opening degree change of the valve 4 may be performed manually or may be changed electrically.

  As described above, in this embodiment, the bypass water channel 21 and the bypass water channel 22 are provided, the mineral cartridge (mineral addition unit) 3 is disposed in the bypass water channel 21, and the bypass channel 21 passes through the water channel 2. A valve 4 is provided that can adjust the ratio between the amount of water that flows and the amount of water that passes through the bypass water channel 22. Therefore, by changing the opening degree of the valve 4, the mixing ratio of the amount of water passing through the bypass water passage 21 and the amount of water passing through the bypass water passage 22 can be changed, and the mineral water concentration can be set to a desired concentration. . That is, according to this embodiment, the water treatment apparatus 1 which can change the density | concentration of mineral water can be obtained.

  Further, according to the present embodiment, by providing the valve 4 at the junction C, it is possible to adjust the ratio of the amount of water passing through the bypass water passage 21 and the amount of water passing through the bypass water passage 22 with one valve. Therefore, the increase in the number of parts can be suppressed and the cost can be reduced.

  By the way, when the valve 4 is provided upstream of the mineral cartridge (mineral addition part) 3, the water that has passed the bypass water channel 21 and added the mineral component and the water that has passed the bypass water channel 22 are joined at the junction C. Although mixed, it is difficult to make the mixing ratio constant at this time. That is, when the valve 4 is provided upstream of the mineral cartridge (mineral addition unit) 3, the concentration of mineral water may change.

  However, according to this embodiment, since the valve 4 is provided at the junction C, the mixing ratio of the water that has passed the bypass water channel 21 and added with the mineral component and the water that has passed the bypass water channel 22 is determined by the valve 4. There is an advantage that mineral water with a more stable concentration can be supplied.

  Further, according to the present embodiment, the mineral addition portion includes the cartridge case 30 having the inflow port 5 provided in the lower portion and the outflow port 6 provided in the upper portion, and the inflow port 5 in the cartridge case 30. Since it comprised with the water purification cartridge 3 arrange | positioned between the outflow ports 6 and provided with the mineral agent storage part 40 in which the mesh (water inflow part) 45 is formed in the cylindrical side wall (side wall) 43, to the detour channel 21 The mineral addition part 3 can be arrange | positioned easily. Further, by providing a mesh (water inflow portion) 45 at the lower portion of the cylindrical side wall (side wall) 43 of the mineral agent storage unit 40, the upper portion of the mesh (water inflow portion) 45 is lower (from Aw1 in FIG. 2). Also, the mineral agent 7 accommodated in the lower part is immersed by the water flowing into the cartridge case 30. That is, the water flowing into the cartridge case 30 can be brought into contact with the mineral agent 7 having a certain volume.

  By the way, when water is brought into contact with the entire mineral agent 7 in the mineral agent storage section 40, the capacity of the mineral agent 7 decreases with the passage of water passing time, and the amount of contact with the water flowing into the cartridge case 30 is reduced. It will decrease. For this reason, even if the amount of water passing through the detour channel 21 is constant, the concentration of the obtained mineral water changes when used for a long time.

  However, according to this embodiment, since the mineral agent 7 that contacts water is a part of the mineral agent 7 in the mineral agent storage unit 40, the mineral agent 7 in the mineral agent storage unit 40 is brought into contact with the entire mineral agent 7. Thus, the amount of contact with water does not decrease each time water is passed. That is, even when used for a long period of time, the amount of mineral added can be made almost constant, and mineral water with a more stable concentration can be obtained.

(Second Embodiment)
Even in the water treatment apparatus 1 according to the present embodiment, the mineral cartridge (mineral addition unit) 3 is arranged in the detour channel 21 of the water passage 2 as in the first embodiment. The raw water that has flowed into the case 30 passes through the mineral agent 7 in the mineral agent storage section 40 to add mineral components, and the generated mineral water flows out from the outlet 6.

  A valve 4 capable of adjusting the ratio of the amount of water passing through the bypass water passage 21 and the amount of water passing through the bypass water passage 22 is provided at the junction C of the bypass water passage 21.

  Here, the water treatment device 1 according to the present embodiment is different from the water treatment device 1 of the first embodiment in the configuration of the mineral cartridge (mineral addition unit) 3.

  In this embodiment, as shown in FIG. 3, the mineral addition portion includes a cartridge case 30 having an inflow port 5 provided in the lower portion and an outflow port 6 provided in the upper portion, and a flow inside the cartridge case 30. The water purification cartridge 3 </ b> A includes a mineral agent storage portion 71 formed above the partition plate 70 disposed between the inlet 5 and the outlet 6.

  Also in this embodiment, as the mineral agent 7, one or more of calcium, sodium, magnesium and the like mixed and solidified is used. This mineral agent 7 is contained in the mineral agent storage unit 71. It is stored in.

  The cartridge case 30 includes a lower case 31 and an upper case 32, and is formed in a substantially cylindrical shape by connecting the lower case 31 and the upper case 32.

  The lower case 31 is formed in a cylindrical shape with a bottom wall 31a provided at the lower end, and the above-described inflow port 5 is formed at the center of the bottom wall 31a. The upper case 32 is formed in a cylindrical shape with a top wall 32a provided at the upper end, and the above-described outlet 6 is formed at the center of the top wall 32a. The lower case 31 and the upper case 32 are fixed by screwing the inner periphery of the lower end portion of the upper case 32 to the outer periphery of the upper end portion of the lower case 31. At this time, the lower case 31 and the upper case 32 are fixed with a liquid-tight structure by sealing the gap between the lower case 31 and the upper case 32 with the O-ring 61.

  The partition plate 70 has a bottom wall 72 that partitions between the inflow port 5 and the outflow port 6 and a substantially cylindrical shape that protrudes from the bottom wall 72 and prevents communication between the mineral agent storage portion 71 and the outflow port 6. And a vertical wall 73.

  In the present embodiment, the bottom wall 72 is closely fitted to the inner periphery of the side wall of the lower case 31, and the upper end 73 a of the vertical wall 73 is protruded downward toward the center of the upper case 32. The partition plate 70 is fixed in the cartridge case 30 by being closely fitted to each other.

  Note that the inner side of the fitting portion 32 b communicates with the outlet 6.

  In this embodiment, a space formed between the cartridge case 30 and the bottom wall 72 and the vertical wall 73 is a mineral agent storage portion 71.

  In the present embodiment, the lower case 31 and the vertical wall 73 are arranged concentrically.

  An annular opening 72 a is formed in the bottom wall 72, and a mesh (water contact portion) 75 that allows water to pass through the opening 72 a but prevents the mineral agent 7 from passing therethrough is attached. The raw water comes into contact with the mineral agent 7 through the mesh 75. And the water which contacted the mineral agent 7 flows in into the center cavity part 73b of the vertical wall 73, and the water which flowed into the center cavity part 73b is discharged from the outflow port 6 through the inner side of the fitting part 32b. The

  The inflow port 5 is provided with a cover portion 51 that covers the vicinity of the downstream side of the inflow port 5, and a plurality of openings 52 are formed around the cover portion 51. The raw water flowing in from the inflow port 5 passes through the opening 52, is distributed in a direction along the bottom wall 72 of the partition plate 70, and comes into contact with the mineral agent 7 through the mesh 75.

  Also according to this embodiment described above, the same operational effects as those of the first embodiment can be obtained.

  Further, according to the present embodiment, the mineral addition portion includes the cartridge case 30 having the inflow port 5 provided in the lower portion and the outflow port 6 provided in the upper portion, and the inflow port 5 in the cartridge case 30. Since the water purification cartridge 3 </ b> A includes the mineral agent storage portion 71 formed above the partition plate 70 disposed between the outlet 6, the mineral addition portion can be easily disposed in the bypass water channel 21.

  Moreover, according to this embodiment, the mesh (contact part with water) 75 which makes the water which flowed in from the inflow port 5 contact the mineral agent 7 in the mineral agent storage part 71 is provided in the bottom wall 72 of the partition plate 70. Thus, the water flowing into the cartridge case 30 can be brought into contact with the mineral agent 7 having a certain area (opening area of the opening 72a). Thus, while making the quantity of the mineral agent 7 which contacts water constant, it is made to contact the whole mineral agent 7 in the mineral agent storage part 71 by making a part of mineral agent 7 contact water. As in the case, the amount of contact with water does not decrease each time water is passed. That is, according to this embodiment, even if it is a case where it is used for a long period of time, the amount of mineral addition can be made almost constant, and mineral water with a more stable concentration can be obtained. In the configuration in which the mesh (contact portion with water) 75 is provided on the bottom wall 72 of the partition plate 70 as in the present embodiment, the water that has flowed into the cartridge case 30 enters the mineral agent storage portion 71, The mineral agent 7 stored below Aw2 in FIG. 3 is immersed by the water that has flowed into the cartridge case 30, but the water that enters the mineral agent storage portion 71 in this way is the cartridge. Since the amount of water flowing into the case 30 is small, it can be considered that the elution amount of the mineral component is determined by the opening area of the opening 72a.

(Third embodiment)
Even in the water treatment apparatus 1 according to the present embodiment, the mineral cartridge (mineral addition unit) 3 is arranged in the detour channel 21 of the water passage 2 as in the first embodiment. The raw water that has flowed into the case 30 passes through the mineral agent 7 in the mineral agent storage section 40 to add mineral components, and the generated mineral water flows out from the outlet 6.

  A valve 4 capable of adjusting the ratio of the amount of water passing through the bypass water passage 21 and the amount of water passing through the bypass water passage 22 is provided at the junction C of the bypass water passage 21.

  Here, the water treatment apparatus 1 according to the present embodiment is mainly different from the water treatment apparatus 1 according to the first embodiment, as shown in FIG. 4, as shown in FIG. The second valve 9 capable of adjusting the amount of water flowing into the mineral cartridge (mineral addition unit) 3 from the bypass water channel 21 is provided on the upstream side.

  In the present embodiment, the second valve 9 is configured such that the motor M can change the opening area (opening degree) that communicates with the bypass water channel 21 of the second valve 9.

  Here, if the second valve 9 is not provided, the following problems may occur.

  First, mineral water is obtained by twisting a faucet or the like to obtain mineral water, and when the water is stopped, the mineral water remains in the mineral cartridge (mineral adding portion) 3. After that, when the water is passed again, the water having the same flow rate as that at the time of the first water flow flows into the mineral cartridge (mineral adding portion) 3, so this influent water and the residual mineral water are mixed to form a slightly high concentration mineral water. Generated. That is, the concentration of the obtained mineral water is different from the desired concentration at the beginning of water flow.

  Therefore, in the present embodiment, the amount of water flowing into the mineral cartridge (mineral addition unit) 3 can be adjusted by changing the opening degree of the second valve 9. Specifically, in the water flow start stage, the amount of water flowing into the mineral cartridge (mineral addition unit) 3 is slightly increased, and the opening degree of the second valve 9 is decreased so as to gradually reach a predetermined flow rate. Thus, the mineral concentration of mineral water obtained during water flow was set to a substantially constant value.

  The motor is controlled by a control unit (not shown).

  Also according to this embodiment described above, the same operational effects as those of the first embodiment can be obtained.

  Further, according to the present embodiment, the amount of water flowing from the bypass water channel 21 to the mineral cartridge (mineral addition unit) 3 can be adjusted upstream of the mineral cartridge (mineral addition unit) 3 of the bypass channel 21. Since the second valve 9 is provided, when the water flow is started again after the water stoppage, the amount of water to be mixed with the mineral water remaining in the mineral cartridge (mineral addition unit) 3 in the water flow start stage is set to the second amount. The valve 9 can be adjusted. And it can suppress that the density | concentration of the mineral water formed with the mineral cartridge (mineral addition part) 3 changes by adjusting the quantity of the water mixed with the remaining mineral water. As a result, mineral water with a more stable concentration can be obtained.

(Fourth embodiment)
Even in the water treatment apparatus 1 according to the present embodiment, the mineral cartridge (mineral addition unit) 3 is arranged in the detour channel 21 of the water passage 2 as in the first embodiment. The raw water that has flowed into the case 30 passes through the mineral agent 7 in the mineral agent storage section 40 to add mineral components, and the generated mineral water flows out from the outlet 6.

Is formed. That is, when the water treatment apparatus 1 is stopped, since the drainage-side passage is opened, water can be circulated from the mineral addition unit-side passage 80b to the drainage-side passage 80c.

  Therefore, at the time of water stoppage, the water remaining in the mineral cartridge (mineral addition portion) 3 is sent from the mineral addition portion side passage 21b to the drainage side piping 21c through the drainage side passage 80c and drained.

  Next, as shown in FIG. 6 (b), when the water treatment apparatus 1 is watered, the water pressure receiving plate 81 e is pressed by the pressure of the raw water flowing into the branch point side passage 80 a, and the water pressure receiving plate 81 e The head 81b is pressed by the raw water flowing down through the communication hole 81f.

  Then, the movable member 81 compresses the spring 82 and moves downward by the pressing by the raw water. As a result, the drainage-side passage is blocked by the packing 83 that has moved downward together with the movable member 81.

  Therefore, when the water treatment apparatus 1 is watered, the drainage side passage is blocked by the packing 83, so that the raw water is sent from the branch point side pipe 21a to the mineral addition part side pipe 21b and is supplied with a mineral cartridge (mineral addition part). ) 3 will be supplied.

  When the water is stopped again, the movable member 81 is lifted upward by the urging force of the spring 82, and the drain side passage is opened. In this way, water remaining in the mineral cartridge (mineral addition unit) 3 is drained through the drain valve 8.

  In place of the drain valve described in the above embodiment, an electromagnetic valve capable of opening and closing the drain side passage opening may be provided.

  Also according to this embodiment described above, the same operational effects as those of the first embodiment can be obtained.

  In addition, according to the present embodiment, since the bypass valve 21 for draining the water remaining in the mineral cartridge (mineral addition unit) 3 at the time of water stoppage is provided in the bypass water channel 21, when water flow is started again after the water stoppage. It is possible to prevent the mineral water remaining in the mineral cartridge (mineral addition unit) 3 from mixing at the initial stage of water flow and changing the concentration of the mineral water. As a result, mineral water with a more stable concentration can be obtained.

(Fifth embodiment)
Even in the water treatment apparatus 1 according to the present embodiment, the mineral cartridge (mineral addition unit) 3 is arranged in the detour channel 21 of the water passage 2 as in the first embodiment. The raw water that has flowed into the case 30 passes through the mineral agent 7 in the mineral agent storage section 40 to add mineral components, and the generated mineral water flows out from the outlet 6.

  Here, the main difference between the water treatment apparatus 1 according to the present embodiment and the water treatment apparatus 1 according to the first embodiment is that, as shown in FIG. 7, a bypass water channel 21 is provided at a branch portion D of the bypass water channel 21. The valve 4 that can adjust the ratio of the amount of water passing through and the amount of water passing through the bypass water channel 22 is provided.

  Also according to this embodiment described above, the same operational effects as those of the first embodiment can be obtained.

  Further, according to the present embodiment, by providing the valve 4 at the branch portion D, it is possible to adjust the ratio of the amount of water passing through the bypass water passage 21 and the amount of water passing through the bypass water passage 22 with one valve. Therefore, the increase in the number of parts can be suppressed and the cost can be reduced.

  Further, by providing the valve 4 at the branch portion D, it is possible to suppress the mineral scale from adhering to the valve 4. Further, since the pressure of the raw water can be received by the valve 4 before flowing into the mineral cartridge (mineral addition portion) 3, the mineral cartridge (mineral addition portion) 3 disposed on the downstream side is thinned, etc. Thus, the strength can be lowered. As a result, the water treatment device 1 can be downsized.
