Description

  The present invention is built in a switching valve device such as a switching cock, performs a multi-stage valve switching operation, forms a plurality of flow channels in the switching valve device, and performs a flow channel switching operation of running water by the switching valve device. The present invention relates to a switching valve cartridge that enables the switching valve device and a switching valve device incorporating the switching valve cartridge.

  As the switching valve device, for example, there is a switching valve (also referred to as a switching cock) that is detachably attached to a water outlet of a faucet. This switching valve is, for example, switchable between a raw water straight position for raw water straight water discharge, a raw water shower position for raw water shower water discharge, and a purified water position for water purification water discharge by a handle, and has three-way flow paths ( A raw water straight channel, a raw water shower channel, and a purified water channel) are embodied as a three-way valve that can be selectively switched. Alternatively, as described in Patent Document 1 (Japanese Patent Laid-Open No. 2004-346958), the switching valve is a four-way channel (raw water straight channel, raw water shower channel, purified water straight channel, purified water shower). For example, as described in Patent Document 2 (Japanese Patent Laid-Open No. 2007-309333), five channels that can be selectively switched in five directions. It is embodied as a two-way valve, or conversely, as described in Patent Document 3 (Japanese Patent Laid-Open No. 2000-266199), it is embodied as a two-way valve capable of selectively switching between two-way flow paths. . That is, the switching valve can be embodied as one that can selectively switch flow paths in two or more directions. Furthermore, although the external water supply apparatus connected to a switching valve is generally a water purifier, it can also be used as apparatuses other than water purifiers, such as a dishwasher. In general, the valve mechanisms of these switching valves are provided with spherical valve bodies and valve seats corresponding to the number of flow paths, and the spherical valve bodies are separated from the valve seats or seated on the valve seats. Opening and closing the valve, or providing a plurality of valve holes in the cylindrical valve body corresponding to the number of flow paths, and communicating with and blocking communication with the valve holes of the corresponding valve seats that rotate the cylindrical valve body in the circumferential direction To switch the flow path.

On the other hand, a valve mechanism using a ceramic disk instead of a spherical valve body has been proposed. For example, Patent Document 4 (Japanese Patent Laid-Open No. 7-229572) discloses a three-way valve using a ceramic disk. As described in the summary of this document, the three-way valve has a cylindrical valve body in which an inflow path and a first outflow path are provided in a discontinuous manner, and a second orthogonal to the first outflow path. An outflow path is provided, and the back of this second outflow path is used as a valve chamber. A fixed and movable ceramic disk valve is provided in this valve chamber, and this disk valve communicates with the inflow path and the first or second outflow path. The three-way valve is switched. Further, the three-way valve is provided with a handle that is locked to the outer periphery of the movable disc of the disc valve and that rotates on the outer periphery of the cylindrical valve body. It is described that the three-way valve becomes compact because there is no handle in the axial direction.

  Here, a switching valve device having a valve mechanism using a ceramic disk is preferable because it has the advantage of being able to be compactly designed as a whole. However, a fixed disk and a movable disk made of a ceramic disk are slid with use. Since the sliding surface is worn by dynamic friction, the desired valve function is not exhibited after a certain period of time. In this case, even when at least one of the fixed disk or the movable disk needs to be replaced due to wear or the like, it is very difficult to replace only the fixed disk or the movable disk that needs to be replaced. It is necessary to replace the whole. Specifically, in the case of the three-way switching valve of Patent Document 4, as described in paragraphs 0008 to 0013, the valve main body includes an inflow side joint portion and a first outflow side joint portion in the axis orthogonal direction. The second outflow side joint portion is screwed to one side in the axial direction, and the first and second outflow side joint portions are orthogonal to each other. The back side of the second outflow side joint portion is a valve chamber of the disc valve. The disk valve is made of ceramic, and a fixed disk and a movable disk are polymerized by applying grease or the like. On the sliding surface side of the fixed disk with respect to the movable disk, a fan-shaped inflow side water inlet and a fan-shaped outflow side water outlet are opened so as to oppose the center of the fixed disk with point symmetry. Further, on the side of the fixed disk opposite to the sliding surface, a packing concave portion for accommodating the collar packing and a cylindrical concave portion for accommodating the two spring receiving cylinders are respectively recessed. One of the two water openings is opened in the packing recess. Each spring receiving cylinder houses a compression coil spring. This coil spring uses a spring receiving tube and a spring receiving tube recessed portion provided in the valve body as a spring receiving member. The movable disk is formed in a wheel shape having a rib wall plate that slides lightly on the outer ring side surface line, and has a partitioned water passage opening. That is, on the sliding surface side of the movable disk, a fan-shaped partition wall having a size surrounding the opening of the inflow side water inlet of the fixed disk is provided, and the second outflow portion side joint portion is provided in the partition wall. One water inlet that communicates with is opened. And it switches to the 1st or 2nd outflow side joint part by this partition wall. Two engaging grooves extending in the axial direction are provided at opposing positions on the outer peripheral surface of the movable disk. In these engaging grooves, the foot of a split knob type handle is inserted through a notch provided in the valve body, and the valve is switched by rotating the knob type handle within a range of 90 degrees. .

  As described above, the three-way switching valve of Patent Document 4 has a precise structure around the disk valve (fixed disk and movable disk) and requires precision for its assembly. It is very difficult to disassemble and reassemble the parts. As a result, even if the fixed disk or movable disk or related parts that constitute the branch structure of the valve mechanism or flow path are worn, deteriorated, damaged, etc. due to the use of the three-way switching valve, the three-way switching valve is disassembled. It is very difficult to replace only the parts, and it is necessary to replace the three-way switching valve itself. In the case of a ceramic disk, small foreign matter such as underwater dust may be pinched on the sliding surface between the fixed disk and the movable disk. In this case, the sliding surface between the fixed disk and the movable disk The water-tight structure in the disk breaks down, causing water leakage to the periphery of the disk valve, or the sliding surface of the fixed disk or movable disk is damaged, and the water-tight structure on those sliding surfaces also breaks down. It is possible that water leaks around the valve. However, even in this case, it is difficult for the three-way switching valve of Patent Document 4 to replace the fixed disk and the movable disk, and it is necessary to replace the entire three-way switching valve.

  In addition, the three-way switching valve of Patent Document 4 has a precise structure around the disk valve (fixed disk and movable disk) and requires precision for its assembly. It is very difficult to disassemble and reassemble. As a result, even if the fixed disk or movable disk constituting the valve mechanism or its related parts are worn, deteriorated, damaged, etc. due to the use of the three-way switching valve, the three-way switching valve is disassembled and only the relevant part is replaced. This is very difficult and requires the three-way switching valve itself to be replaced.

  Therefore, the present invention can be detachably mounted in the main body case of various switching valve devices including the raw water / purified water switching valve device by integrally assembling the valve mechanism including the disk valve and related parts into a cartridge. It is an object of the present invention to provide a switching valve cartridge that can be easily replaced by a single valve mechanism such as a disk valve, and a switching valve device in which the switching valve cartridge is assembled.

  The cock main body 10, the water purification connecting member 30, the inflow side main body 110, the valve operating member 120, and the outflow side main body 150 can be formed of a resin material such as ABS resin, and various O-rings O and O The packing such as the water packing 141 can be formed of a synthetic rubber such as EPDM. Furthermore, the spherical body 191a, the coil spring 191b, and the set screw 191c can be formed of stainless steel or the like.

  In the state where the switching valve cartridge is housed in the cock body 10 as described above, as shown in FIGS. 13 and 14, the switching valve cartridge is connected to the mounting port 15a via the O-ring O mounted on the short cylindrical portion 112. Mounted watertight. In this state, since the handle 50 is mounted integrally with the cartridge body 100, the movable disk 131 as a valve mechanism can be operated from the outside. That is, when the handle 50 is rotated by a predetermined angle in either the forward or reverse direction, the movable disk 131 is rotated by the same angle in the corresponding direction via the operation panel 123 of the valve operation member 120. At this time, the movable disk 131 and the fixed disk 133 are coaxially mounted in the valve chamber of the cartridge main body 100 with the opposed surfaces being in close contact with each other. At this time, the spherical body 191a is in contact with the annular member 121 of the valve operating member 120 in an elastically pressed state. Therefore, when the handle 50 is rotated in either the forward or reverse direction, the valve operating member 120 rotates integrally, and a click feeling is imparted when the spherical body 191a is fitted in the positioning groove 121a of the annular member 121. At the same time, the handle 50 is positioned at a predetermined angular position (raw water straight position, purified water position, raw water shower position). That is, each time the handle 50 is rotated 60 degrees, the handle 50 is positioned by each positioning groove 121a of the annular member 121, and is positioned in six steps during one rotation (360 degrees). At this time, at each positioning angle position of the handle 50, the first and second water passage holes 132a and 132b of the movable disk 131 are replaced with the first and second raw water straight water passage holes 134a and 134b of the fixed disk 133, respectively. The first and second purified water passage holes 135a and 135b and the first and second raw water shower passage holes 136a and 136b communicate with each other in alignment.

  On the other hand, as shown in FIG. 14, in the mounted state of the switching valve cartridge, the O-ring O on the short cylindrical portion 112 and the O-ring O on the short cylindrical portion 118 are on both sides of the raw water inflow hole 12a of the inflow portion 12. The inner peripheral surface of the base 11 of the cock body 10 is water-tight over the entire circumference at the portion of the outlet portion 13 closer to the discharge port 15a than the first water discharge space 13a and the inner peripheral surface of the mounting portion 15a of the mounting portion 15. The O-ring O communicates only with the raw water inflow hole 12a (communication with the first water discharge space 13a and the second water discharge space 13b of the outflow portion 13 and the water purifier water supply hole 14a). A ring-shaped water passage space is formed. In this state, of the pair of water inflow openings 114 a formed in the male screw part 114 of the inflow side main body 110, one of the water inflow openings 114 a passes through the raw water inflow hole 12 a of the inflow part 12 of the cock main body 10. Opposite the raw water inlet 23b. Furthermore, at this time, in the water flow space between the pair of O-rings O, the other water inflow opening 114 a is disposed at a position facing the outflow portion 13. Therefore, the other water inflow opening 114a also communicates with the raw water inlet 23b from the water flow space through the raw water inflow hole 12a of the inflow portion 12. Therefore, the raw water flowing into the cock main body 10 from the raw water inlet 23b flows into the inflow side main body 110 through the pair of water inflow openings 114a through the water flow space. At this time, in the inflow side main body 110, a pair of water flow recessed parts 123a, 123b of the operation panel 123 are opposed to the pair of water inflow openings 114a. Accordingly, the raw water flowing in from the pair of water inflow openings 114a is guided on the pair of water passage recesses 123a and 123b, respectively, and a pair of water passages of the movable disk 131 disposed to face the pair of water passage recesses 123a and 123b. It flows into the holes 132a and 132b.

  Therefore, when the valve operating member 120 is rotated in either the forward or reverse direction by the handle 50 and positioned at, for example, the raw water straight position, the pair of water passage holes 132 a and 132 b of the movable disk 131 are paired with the pair of raw water of the fixed disk 133. The raw water from the pair of water passage holes 132a and 132b of the movable disk 131 communicates with the straight water passage holes 134a and 134b, and the pair of raw water straight water passage holes 134a and 134b of the fixed disk and the pair of water stop packings 141 pass. The water passes through the water holes 142a and 142b, respectively, and flows into the pair of raw water straight water passages 171a and 171b of the switching member 150, respectively. The raw water flowing into the pair of raw water straight water passages 171a and 171b is opened at the outer peripheral surface of the short cylindrical portion 155 as the first flow path groove, as shown in FIG. The fluid flows out of the switching member 150 from 155a and 155b, respectively. At this time, as shown in FIG. 14, the O-ring O on the short cylindrical portion 157 of the switching member 150 and the O-ring O on the short cylindrical portion 118 of the inflow side main body 110 cause the first water discharge of the outflow portion 13. In order to seal the inner peripheral surface of the base 11 of the cock body 10 on both sides of the space 13a in a water-tight manner over the entire circumference, only the first water discharge space 13a of the outflow portion 13 communicates between the O-rings O. A ring-shaped water passage space is formed (which blocks communication with the raw water inflow hole 12a of the inflow portion 12, the second water discharge space 13b of the outflow portion 13, and the water purifier water supply hole 14a). Therefore, the raw water from the pair of raw water straight openings 155a and 155b formed in the short cylindrical portion 155 at the position facing the water flow space passes through the first water discharge space 13a from the water flow space, and the water discharge port. It flows into the foam inner core 26 in the inner peripheral wall 24 b of 24 and is discharged from the water outlet (straight water outlet) of the foam inner core 26. That is, the raw water from the upper raw water straight opening 155 a circulates in the water flow space along the first flow path groove formed on the outer peripheral surface of the short cylindrical portion 155 and finally discharges the foam core 26. It is discharged from the outlet. On the other hand, the raw water from the lower raw water straight opening 155b that is 180 degrees away from the raw water straight opening 155a directly faces the straight water outlet of the inner peripheral wall 24b and the foam core 26 inside thereof. Then, it flows directly to the foam core 26 and is discharged from the outlet of the foam core 26.

  When the valve operating member 120 is rotated 60 degrees clockwise by the handle 50 from the raw water straight position and positioned at the raw water shower position, the pair of water passage holes 132a and 132b of the movable disk 131 are paired with the pair of fixed disks 133. The raw water from the pair of water holes 132a and 132b of the movable disk 131 communicates with the raw water shower water holes 136a and 136b, and the pair of raw water shower water holes 136a and 136b of the fixed disk and the pair of water stop packings 141 The water passes through the water passage holes 144a and 144b and flows into the pair of raw water shower water passages 172a and 172b of the switching member 150, respectively. The raw water that has flowed into the pair of raw water shower channels 172a and 172b, respectively, is opened at the outer peripheral surface of the short cylindrical portion 159 as the second flow channel groove, as shown in FIG. The fluid flows out of the switching member 150 from 155a and 155b, respectively. At this time, as shown in FIG. 14, the O-ring O in the ring groove 162 of the switching member 150 and the O-ring O on the short cylindrical portion 157 of the switching member 150 are in the second water discharge space 13 b of the outflow portion 13. The inside of the cock body 10 is elastically in close contact with both sides so as to shield all the communication with the raw water inflow hole 12a of the inflow portion 12, the communication with the first water discharge space of the outflow portion 13 and the communication with the water passage 14a. In order to seal each peripheral surface in a watertight manner, a water flow space communicating with the second water discharge space 13b is formed between the O-rings O. Accordingly, the raw water from the pair of raw water shower openings 159a and 159b formed in the short cylindrical portion 159 located at the position facing the water flow space passes through the second water discharge space 13b from the water flow space, and the water discharge port. 24 flows into the 2nd water discharge space 13b between the outer peripheral wall 24a and the inner peripheral wall 24b, and is discharged from the shower water discharge port which consists of the bottom wall 24c. That is, the raw water from the raw water shower opening 159a on the diagonally upper side and the raw water from the raw water shower opening 159b on the diagonally lower side at a position 180 degrees away from the raw water shower opening 159a are respectively in the short cylindrical portion 159. It circulates in the water flow space along the second flow path groove formed on the outer peripheral surface, and is finally discharged from the shower spout.

  Further, the valve operation member 120 is rotated counterclockwise by the handle 50 from the raw water straight position, or the valve operation member 120 is rotated clockwise by the handle 50 from the raw water shower position, When positioned, the pair of water passage holes 132 a and 132 b of the movable disk 131 communicate with the pair of purified water passage holes 143 a and 143 b of the fixed disk 133, and raw water from the pair of water passage holes 132 a and 132 b of the movable disk 131. However, it passes through the pair of water purification holes 143a, 143b of the fixed disk and the pair of water passages 143a, 143b of the water blocking packing 141, respectively, and enters the pair of water purification passages 172a, 172b of the switching member 150, respectively. Inflow. The raw water that has flowed into the pair of water purification channels 172a and 172b flows out of the switching member 150 from the pair of water purification openings 163a and 163b opened at the circular end surface 163, as shown in FIG. . At this time, as shown in FIG. 14, the O-ring O in the ring groove 162 of the switching member 150 seals the periphery of the water passage hole 14 a at the end opposite to the mounting opening 15 a of the switching cock 10 in a watertight manner. Therefore, the O-ring O communicates only with the water purifier water supply hole 14a (communication with the raw water inflow hole 12a of the inflow portion 12 and the first water discharge space 13a and the second water discharge space 13b of the outflow portion 13). A water flow space is formed. Accordingly, the raw water from the pair of water purification openings 163a and 163b formed on the circular end surface 163 located at a position facing the water flow space passes through the water purifier water supply hole 14a from the water flow space and is connected to the water purification connecting member 30. From the water supply hole insertion portion 34 to the water purifier water supply portion 32, and then flows into the water purifier water supply hose attached by the attachment nut 36 to be supplied into the water purifier. Thereafter, the purified water from the water purifier flows into the purified water inflow portion 33 from the purified water hose attached to the purified water inflow portion 33 of the water purifier connecting member 30 by the attachment nut 37, and then passes through the inflow hole mounting portion 35 to the cock body 10. Into the purified water inflow hole 14b. At this time, the purified water inflow hole 14 b is formed between the O-ring O on the short cylindrical portion 157 of the switching member 150 and the O-ring O on the short cylindrical portion 118 of the inflow side main body 110. Communicate only to Therefore, the purified water from the purified water inflow hole 14b of the cock body 10 is foamed in the inner peripheral wall 24b of the water outlet 24 from the water passing space through the first water discharging space 13a in the same manner as in the case of the raw water straight discharge. It flows into the inner core 26 and is discharged from the water outlet (straight water outlet) of the foam inner core 26. At this time, the raw water straight openings 155a and 155b are opened on the outer peripheral surface of the short cylindrical portion 155 of the first flow path groove through which the purified water flows, but the water passage holes 132a and 132b of the movable disk 131 are Since only the purified water passage holes 134a and 134b of the fixed disk 133 communicate with the raw water straight passage holes 134a and 134b, the passage of the purified water from the raw water straight openings 155a and 155b is performed through the straight passages 171a and 171a. There is no backflow in 171b.

  In this way, by rotating the handle 50 in either the forward or reverse direction, the raw water straight water discharge (water discharge from the foam inner core 26), the purified water discharge (water discharge from the foam inner core 26), and the raw water shower water discharge 3 in order. It is possible to switch to different types of water discharge. Further, the handle 50 can be rotated indefinitely in either the forward or reverse direction, and the switching cock of the present embodiment is configured so that the raw water straight water discharge and the purified water are within a rotation angle range of 180 degrees by the switching valve cartridge. Perform three-stage valve switching operation for water discharge and raw water shower discharge, and further perform three-stage valve switching operation for the second raw water straight water discharge, purified water discharge, and raw water shower discharge within the next 180 degree rotation angle range. become. That is, the switching cock of the present embodiment performs the three-stage water discharge state switching operation (valve switching operation) twice while rotating once (360 degrees), and continuously rotates. Thus, the three-stage water discharge state switching operation can be continuously performed indefinitely.

  On the other hand, in the switching valve cartridge according to the present embodiment, the cartridge main body 100 includes the movable disk 131, the fixed disk 133, and related parts in the cartridge body 100 when the quality deteriorates due to wear, deterioration, breakage, or the like. A small foreign matter (narrow object) such as underwater dust is sandwiched between the fixed disk 133 (sliding contact surface), and the watertight structure on the sliding contact surface between the fixed disk 133 and the movable disk 131 is destroyed. Even when water leaks to the surface, or the sliding contact surface of the fixed disk 133 or the movable disk 131 is scratched, and the watertight structure on those sliding contact surfaces collapses and water leaks to the surroundings. The cock body 10 can be easily removed and replaced. That is, since the cartridge main body 100 is screwed into the cock main body 10 by screwing the male screw 114, the cartridge main body 100 is detachable in a watertight manner. The entire switching valve cartridge can be easily removed from the mounting opening 15a of the cock body 10. Further, as described above, the switching valve cartridge of the present embodiment incorporates all the mechanisms (valve operating member 120 and the like) necessary for the valve switching operation, and is built in the switching valve device body such as the cock body 10. Sometimes, the outer peripheral surface is structured to form a flow path (flow channel groove, etc.) corresponding to the number of flow paths with the inner peripheral surface of the switching valve device main body. It is possible to complete a desired switching valve device simply by installing the interior, and the cost of the switching valve device itself can be greatly reduced with versatility.

  Further, the switching valve cartridge according to the present embodiment itself makes the valve operation member 120 easily detachable from the inflow side main body 110, the movable disk 131 easily attachable to and detachable from the valve operation member 120, and Since the fixed disk 133 water-stop packing 141 can be easily attached to and detached from the switching member 150 and the switching member 150 is easily attached to and detached from the inflow side main body 110, assembly, disassembly, reassembly, etc. can be easily performed. For example, it is possible to replace only the movable disk 131 or the fixed disk 133. In order to remove the switching member 150 from the inflow side main body 110, the claw portion at the tip of the locking projection 152 exposed from the engagement hole 115a of the inflow side main body is pressed inward to be elastically deformed, and the switching member 150 is removed. Pull forward to remove it.

  By the way, the switching valve cartridge of the present invention is not limited to the above-described embodiment, and various modifications are possible as long as the object of the invention can be achieved. That is, as a switching valve device that houses a switching valve cartridge, as in the above embodiment, the raw water straight outlet and the raw water shower outlet are used as the first and second water outlets, and the third water outlet is used. In addition to a switching cock as a three-way valve that uses a water purifier water supply port connected to a water purifier that is an external water supply device, connect an external water supply device (such as a water purifier, a water conditioner, or a water purifier) other than a water purifier. It may be embodied in a switching cock. In addition, the raw water straight water outlet, the raw water shower water outlet, and the water purifier water outlet as the first, second, and third water outlets in the case of the three-way switching valve are all examples as examples, and other than these. Moreover, as long as it is set as the water outflow port provided in the three-way switching valve which switches a flow path in three ways, it can apply to arbitrary things. Furthermore, since the switching cock of the above embodiment has a configuration in which a water purifier is connected as an external water supply device and the purified water is recirculated and flows into the interior, in addition to the raw water inlet (first water inlet), Corresponding to the 3 water outlets, a purified water inlet (second water outlet) for inflowing recirculating water (purified water) from the water purifier is provided, and water is discharged from the first water outlet (raw water straight outlet). However, when the third water outlet is connected to a third water outlet that does not return water such as a dishwasher, the second water inlet becomes unnecessary. In addition, when connecting to the water purifier of the type which provided the water discharge pipe, since there is no circulation of purified water, the 2nd water inflow port becomes unnecessary. In the switching cock of the above embodiment, the water from the first water inflow port flows into the inside through the water inflow opening provided on the outer peripheral surface of the axial end side (inflow side main body 110) of the switching valve cartridge. Water to one water outlet (raw water straight outlet) is guided from the first channel groove by flowing out from one opening on the outer peripheral surface of the other axial end side (switching member 150) of the switching valve cartridge, Water to the second water outlet (raw water shower outlet) is discharged from the other opening on the outer peripheral surface of the other axial end side (switching member 150) of the switching valve cartridge and guided by the second channel groove, 3 flows out from the opening of the other end surface in the axial direction of the switching valve cartridge (end surface of the switching member 150) to the water outlet (water purifier water supply port) 3 and is guided by the water passage (water purifier water supply hole 14a) of the cock body 10. In addition to this, A third flow path groove is provided on the outer peripheral surface of the other end side in the axial direction of the valve cartridge (switching member 150) further on the back side (end surface side of the switching member 150) than the other opening. A water passage for the water outlet may flow out from an opening provided in the third channel groove and may be introduced into the third water outlet (water purifier water supply port).

  In addition to the three-way switching valve, the switching valve cartridge of the present invention may be embodied in a switching valve device that performs two-way valve switching between two flow paths such as a water passage raw water straight and a raw water shower. . In this case, for example, the third water outlet and the second water inlet are omitted from the cock body 10 (the water purification connecting member 30 is closed), and the third water passages 172a, 172b and The third openings 163a and 163b are omitted, and the first water passages 171a and 171b and the second water passages 173a and 173b are arranged two by two at an angle of 360 degrees in the circumferential range of 360 °. The first water passages 171a and 171b and the second water passages 173a and 173b are configured to be opened by the first flow path groove and the second flow path groove on the outer peripheral surface of the switching member 150, respectively. be able to. In this case, the water passage holes of the fixed disk (and the water stop packing) are arranged in the same number (four pieces) and the same cross-sectional shape as the water passage and at the same angular interval (90 degree interval). The pair of water passage holes are arranged in the same cross-sectional shape as the water passage holes of the fixed disk at intervals of 180 degrees. In addition, the positioning grooves 122a of the annular member 122 are also arranged at the same angle interval (90 degree interval) as the same number (four) as the water passage holes. Further, the switching valve cartridge of the present invention may be embodied in a switching valve device that switches four or more valves between four or more flow paths, for example. In this case, for example, an additional water outlet (fourth water outlet...) Is provided in the cock body 10 (corresponding to the number of channels added to the three channels), and added to the three channels. An additional channel groove is provided (corresponding to the number of channels to be performed), and the number of water passages corresponding to the number of channels is equiangularly divided into an angular range of 360 in the circumferential direction (an angle of the number of channels divided by 360 degrees). The added water passages can be configured so as to open at the added channel grooves on the outer peripheral surface of the switching member 150, respectively. In this case, the water passage holes of the fixed disk (and the water stop packing) have the same number and the same cross-sectional shape as the water passages, and are arranged at the same angular intervals. The same cross-sectional shape as the water passage hole is arranged at intervals of 180 degrees. In addition, the positioning grooves 122a of the annular member 122 are also arranged at the same angular intervals as the same number as the water passage holes.

  Further, the switching valve cartridge of the present invention forms a pair of water passage holes 132a and 132b in the movable disk 131 as a valve mechanism, and has a water passage hole (corresponding to the number corresponding to the number of flow paths in the movable disk 133). The number of pairs of water flow holes) 134a, 134b, 135a, 135b, 136a, 136b is provided, and the valve switching operation of a predetermined number of stages (three stages in the case of a three-way valve) is performed twice within a range of 360 degrees. However, since the first problem of the present invention is that the entire valve switching operation mechanism using the ceramic disk is made into a cartridge and exhibits the desired effect, one movable disk is used as the valve mechanism. It is also possible to provide a structure in which water holes are provided and the fixed disks are provided with the same number of water holes as the number of flow paths. In this case, the number of water passages is the same as the number of water passage holes. Including this case, the number of openings for water passages is usually the same as the number of water passages (one opening for one water passage), but the water passage is branched halfway. It is also possible to adopt a configuration that opens at a plurality of positions (for example, two openings for one water passage). However, when the number of water passage holes and water passages that are twice the number of flow paths are provided as in the above embodiment, the valve switching operation of a predetermined number of stages can be performed twice within the range of 360, Further, since the valve switching operation can be continuously performed in the rotation direction, the operation is easy, and a specific effect that the usability is improved can be obtained.

  Further, as described above, the switching valve cartridge of the present invention forms the flow path by bringing the O-ring mounted at a predetermined position on the outer peripheral surface of the switching member into contact with the peripheral surface of the main body case in a watertight manner. As long as the O-ring has a circular peripheral surface portion that allows water-tight contact with the O-ring, the valve device can be applied to any structure. Further, since the switching member has a simple structure, it can be easily manufactured by metal forging or die casting as well as plastic molding.
