By inserting the fixing nut 70 in this way, when the fixing nut screw portion 73 of the fixing nut 70 reaches the portion of the unit housing portion 35 where the case side screw portion 37 is formed, the fixing nut screw portion 73 is moved to the case side screw. Screwed into the portion 37.

  At that time, the tool hook portion 74 of the fixing nut 70 comes out of the unit housing portion 35. Therefore, when the fixing nut screw portion 73 is screwed to the case side screw portion 37, the fixing nut 70 is Then, a tool is hung on the tool hanger 74 and rotated by using the tool. As a result, the fixing nut screw portion 73 of the fixing nut 70 is screwed into the case side screw portion 37.

  As described above, when the fixing nut screw portion 73 is screwed into the case side screw portion 37, the fixing nut 70 gradually enters the unit housing portion 35, and the abutting portion 77 of the fixing nut 70 is moved to the unit case 100. It contacts the end of the case body 101 on the bearing holding part 110 side. Accordingly, the movement of the valve unit 80 in the direction of the opening of the unit accommodating portion 35 is restricted, and the valve unit 80 is fixed while being accommodated in the unit accommodating portion 35.

  In addition, the pedestal cover 60 is attached to the cover attachment portion 51 in the main body case 30 that houses the valve unit 80. The mounting surface is mounted in a direction facing the cover mounting portion 51. At that time, the lever 170 or the lever shaft 90 is attached in a state where the O-ring 203 is attached to the O-ring groove 57 of the cover attaching portion 51 through the lever hole 62 formed in the flat portion 61.

  Since the outer peripheral portion 63 of the pedestal cover 60 has an inner diameter larger than the outer diameter of the cover mounting portion 51, when the pedestal cover 60 is mounted on the cover mounting portion 51, the outer peripheral portion 63 covers the cover mounting portion 51. To overlay. In this case, the O-ring 203 attached to the O-ring groove 57 is compressed by the outer peripheral portion 63 at an initial stage where the outer peripheral portion 63 is superimposed on the cover attaching portion 51. In this state, when the pedestal cover 60 is moved in the direction approaching the main body mounting portion 50, the O-ring engaging portion 65 formed on the outer peripheral portion 63 moves to the position of the O-ring 203. 203 enters the O-ring engagement portion 65. Thereby, the movement of the base cover 60 in the direction along the central axis is restricted by the O-ring 203.

  Further, in this way, when the pedestal cover 60 is attached to the cover attachment portion 51, the cover side flat portion 68 formed on the protruding portion 67 of the pedestal cover 60 is replaced with the attachment portion side flat portion 52 of the cover attachment portion 51. Install in the overlapping direction, with both sides overlapping. Further, when the pedestal cover 60 is attached to the cover attachment portion 51 as described above, the protruding portion 67 of the pedestal cover 60 is in a state of being close to the main body attachment portion 50. For this reason, in the space formed by the pedestal cover 60, the main body attachment portion 50, and the cover attachment portion 51, the proportion of the protrusions 67 increases, so the volume of the space becomes small.

  Next, the adjustment of water discharge by the faucet device 5 will be described. Water pressure is constantly applied to the two inflow pipes 181 from the water supply pipe and the hot water apparatus, and the faucet apparatus 5 flows out from the inflow pipe 181 side. By adjusting the flow rate of water and hot water flowing to the pipe 182 side with the faucet body 20, the amount and temperature of water discharged from the water outlet 15 are adjusted. Thus, when adjusting the amount of water discharge with the faucet main body 20, it adjusts by changing the tilt angle and tilt direction of the lever 170.

  Here, the operation of the lever 170 will be described. The lever 170 is connected to the lever shaft 90 of the valve unit 80, and the lever shaft 90 has a spherical portion 91 and a bearing on the case side lever shaft support portion 115 of the unit case 100. 120 is supported by the bearing side lever shaft support portion 120. Further, the pin 92 provided in the spherical portion 91 enters the lever shaft support portion groove portion 125.

  For this reason, the lever 170 and the lever shaft 90 can tilt in two directions, with the central portion of the spherical portion 91 as the center, the formation direction of the lever shaft support portion groove portion 125 and the rotation direction around the central axis of the pin 92. Therefore, it is supported so as to be tiltable in all directions. On the other hand, since the pin 92 provided in the spherical portion 91 enters the lever shaft support portion groove portion 125, the rotation of the lever shaft 90 around the central axis of the lever shaft 90 is restricted.

  Further, the portion of the lever shaft 90 on the spherical end portion 95 side passes through the operation range limiting hole 126 that is opened in a fan shape. For this reason, the tilting direction and angle of the lever shaft 90 that can be tilted in any direction are limited by the operation range limiting hole 126. That is, the lever shaft 90 can be tilted within a range in which the portion on the spherical end 95 side abuts on the operation range limiting hole 126. For this reason, the lever shaft 90 is in a neutral state, that is, in a state where the tilt angle is along the central axis of the case main body 101 or the like, and the portion where the rotation restriction hole 104 of the case main body 101 is located on the spherical end 95 side. It is possible to tilt within a predetermined range away from the head.

  Further, the rotation restricting portion 137 of the disc cap 130 enters the rotation restricting hole 104 of the case main body 101 when the lever shaft 90 is in a neutral state, and cannot be turned or swung. Further, the movable disk 140 in which the disk side engaging portion 145 is engaged with the cap side engaging portion 135 of the disk cap 130 moves with the movement of the disk cap 130, but when the lever shaft 90 is in the neutral state. The movable disk 140 also stops at a position near the rotation restricting hole 104.

  On the other hand, water or hot water flowing into the faucet body 20 from the inflow pipe 181 flows from the inflow hole 41 of the main body case 30 into the back cover side inflow hole 167 of the back cover 160, and the disk side inflow hole 155 of the fixed disk 150. Is flowing in. The fixed disk 150 is formed with a disk side outflow hole 158 communicating with the outflow pipe 182 through the back cover side outflow hole 168 of the back cover 160 and the outflow hole 42 of the main body case 30. The inflow hole 155 and the disk side outflow hole 158 can communicate with each other via the switching hole 147 of the movable disk 140.

  Further, since the movable disk 140 moves together with the disk cap 130 that moves by tilting the lever shaft 90, the communication state between the disk-side inflow hole 155 and the disk-side outflow hole 158 via the switching hole 147 depends on the lever shaft. It is switched by 90 tilted states.

  41 is a cross-sectional view taken along the line P-P in FIG. 7, and is an explanatory diagram illustrating a relationship between the movable disk and the fixed disk when the lever shaft is in a neutral state. When the lever shaft 90 is in the neutral state, when the movable disk 140 is positioned closer to the rotation restricting hole 104, the switching hole 147 of the movable disk 140 overlaps only with the disk-side outflow hole 158 of the fixed disk 150, and the disk Only the side outflow hole 158 communicates. That is, when the movable disk 140 is positioned closer to the rotation restricting hole 104 and the switching hole 147 is located closer to the rotation restricting hole 104, the switching hole 147 is similarly located closer to the rotation restricting hole 104. It communicates only with the outflow hole 158. For this reason, when one of the two disk side inflow holes 155 formed in the fixed disk 150 is a cold water side inflow hole 156 communicating with the water supply pipe, and the other is a hot water side inflow hole 157 communicating with the hot water device. The cold water side inflow hole 156 and the hot water side inflow hole 157 are not communicated with the disk side outflow hole 158.

  That is, the cold water side inflow hole 156 and the hot water side inflow hole 157 are closed by the movable disk 140, and the water flowing into the cold water side inflow hole 156 and the hot water flowing into the hot water side inflow hole 157 are blocked by the movable disk 140. . As a result, water and hot water do not flow into the disk side inflow hole 155, and they do not flow into the outflow pipe 182, so that the water faucet device 5 is stopped.

  On the other hand, when the lever shaft 90 is tilted within the range of contact with the operation range limiting hole 126, the disc cap 130 in which the spherical end portion 95 is inserted into the shaft end insertion portion 136 is tilted to the lever shaft 90. Move according to. FIG. 42 is an explanatory diagram when the lever shaft of FIG. 7 is tilted. For example, when the lever shaft 90 is tilted in a direction in which the spherical end portion 95 side separates from the rotation restricting hole 104, the disc cap 130 moves in a direction in which the rotation restricting portion 137 comes out of the rotation restricting hole 104. In this case, the movable disk 140 also moves together with the disk cap 130, and the communication state between the disk side inflow hole 155 and the disk side outflow hole 158 via the switching hole 147 changes from the case where the lever shaft 90 is in the neutral state.

  FIG. 43 is a cross-sectional view taken along the line QQ in FIG. 42, and is an explanatory diagram showing the relationship between the movable disk and the fixed disk in a state where the lever shaft is tilted. When the movable disk 140 moves away from the rotation restricting hole 104, the switching hole 147 formed in the movable disk 140 also moves away from the rotation restricting hole 104 as compared with the case where the lever shaft 90 is in the neutral state. Moving. Even in this case, since the tilt range of the lever shaft 90 is limited by the operation range limiting hole 126, the switching hole 147 is maintained in communication with the disc-side outflow hole 158.

  Further, in the fixed disk 150, the disk-side inflow hole 155 is formed in the direction away from the rotation restricting hole 104. Therefore, when the movable disk 140 moves in the direction away from the rotation restricting hole 104, the switching hole is provided. 147 overlaps both the cold water inflow hole 156 and the hot water inflow hole 157. Thereby, the switching hole 147 communicates with the cold water side inflow hole 156 and the hot water side inflow hole 157.

  Further, since the switching hole 147 is maintained in communication with the disk side outflow hole 158, the switching hole 147 communicates with the cold water side inflow hole 156, the hot water side inflow hole 157, and the disk side outflow hole 158. To do. In other words, the disk side outflow hole 158 communicates with both the cold water side inflow hole 156 and the hot water side inflow hole 157 through the switching hole 147.

  As a result, the water flowing through the cold water inflow hole 156 and the hot water flowing through the hot water side inflow hole 157 both flow through the switching hole 147 to the disk side outflow hole 158 and flow into the outflow pipe 182 in a state where both are mixed. This mixed water of hot water and hot water flows into the water discharge head 14 through the hose 185 and is discharged from the water discharge port 15 of the water discharge head 14.

  FIG. 44 is an explanatory diagram of the operation range of the lever shaft. The lever shaft 90 can be tilted within a range in contact with the operation range limiting hole 126. However, since the operation range limiting hole 126 is opened in a fan shape, the lever shaft 90 is tilted. The operation range OA, which is a range that can be performed, is also fan-shaped. Further, the communication state of the cold water side inflow hole 156, the hot water side inflow hole 157, and the disk side outflow hole 158 of the fixed disk 150 varies depending on the position of the switching hole 147 of the movable disk 140 that moves by tilting the lever shaft 90. To do.

  Specifically, since the tilt range of the lever shaft 90 is restricted even when the rotation restricting portion 137 is tilted in the direction of coming out of the rotation restricting hole 104 of the case main body 101, the rotation restricting portion 137 is not limited to the rotation restricting hole 104. The disc cap 130 can also move in the horizontal direction when the amount of the rotation restricting portion 137 coming out is large. That is, when the portion of the rotation restricting portion 137 coming out of the rotation restricting hole 104 is increased by tilting the lever shaft 90, the disc cap 130 is in contact with the rotation restricting portion 137 and the rotation restricting hole 104. It becomes possible to rotate in the horizontal direction around the center.

  For this reason, the movable disk 140 can also be rotated in the horizontal direction together with the disk cap 130, and the range in which the switching hole 147 of the movable disk 140 overlaps the cold water inflow hole 156 and the hot water side inflow hole 157 of the fixed disk 150 is not limited. The moving disk 140 changes depending on the position in the horizontal direction.

  Accordingly, the flow rate of water flowing from the cold water inflow hole 156 to the disk side outflow hole 158 and the flow rate of hot water flowing from the hot water side inflow hole 157 to the disk side outflow hole 158 vary depending on the position of the movable disk 140, that is, the operation. It changes depending on the position of the lever shaft 90 on the range OA. For example, in the operation range OA, one end side of the fan-shaped arc portion is a low temperature position LP where the flow rate from the cold water side inflow hole 156 to the disk side outflow hole 158 is the largest, and the other end side of the arc is The high temperature position HP where the flow rate from the hot water side inflow hole 157 to the disk side outflow hole 158 is the largest is obtained.

  FIG. 45 is a cross-sectional view taken along the line QQ in FIG. 42, and is an explanatory diagram showing the relationship between the movable disk and the fixed disk when the lever shaft is in the low temperature position. When the lever shaft 90 is in the low temperature position LP, the movable disk 140 rotates to a position near the cold water inflow hole 156 while leaving the rotation restricting hole 104 of the case main body 101. Therefore, the switching hole 147 of the movable disk 140 communicates only with the cold water inflow hole 156 and the disk side outflow hole 158, and the hot water side inflow hole 157 is closed by the movable disk 140.

  Accordingly, the hot water flowing into the hot water side inflow hole 157 is blocked by the movable disk 140, while the water flowing into the cold water side inflow hole 156 flows into the disk side outflow hole 158 via the switching hole 147. Only water flowing into the faucet body 20 from the water supply pipe is discharged from the water outlet 15 of the head 14.

  FIG. 46 is a cross-sectional view taken along the line QQ in FIG. 42, and is an explanatory diagram showing the relationship between the movable disk and the fixed disk when the lever shaft is in the high temperature position. When the lever shaft 90 is in the high temperature position HP, the movable disk 140 rotates away from the rotation restricting hole 104 to a position near the hot water side inflow hole 157. For this reason, the switching hole 147 of the movable disk 140 communicates only with the hot water side inflow hole 157 and the disk side outflow hole 158, and the cold water side inflow hole 156 is closed by the movable disk 140.

  Accordingly, the water flowing into the cold water side inflow hole 156 is blocked by the movable disk 140, while the hot water flowing into the hot water side inflow hole 157 flows into the disk side outflow hole 158 through the switching hole 147. Only hot water flowing into the faucet body 20 from the hot water device is discharged from the water outlet 15 of the head 14.

  When discharging water with the faucet device 5, the amount of discharged water and the temperature of discharged water are adjusted by tilting the lever 170 connected to the lever shaft 90 within the operation range OA. be able to.

  FIG. 47 is a detailed view of a portion R in FIG. In the faucet device 5, the water discharge is adjusted by operating the lever 170. At this time, the opportunity to operate with wet hands after washing with water or hot water discharged from the water outlet 15. Will increase. Therefore, water easily adheres to the periphery of the lever 170 and the pedestal cover 60, and this water is a lever hole gap 210 that is a gap between the lever hole 62 of the pedestal cover 60 and the umbrella portion 173 of the lever 170. Therefore, it is easy to enter the pedestal cover 60. When water enters the pedestal cover 60 from the lever hole gap 210, a part of this water flows inside the tool hook 74 of the fixing nut 70.

  The bearing holding part 110 of the case main body 101 is located inside the fixing nut 70, and the inner side formed on the inner peripheral surface 72 of the fixing nut 70 is between the fixing nut 70 and the bearing holding part 110. The sealing performance is maintained by the O-ring 202 mounted in the O-ring groove 79. For this reason, the water flowing inside the tool hook 74 does not flow below the O-ring 202, and the water flow toward the valve unit 80 is blocked by the O-ring 202.

  Further, since the drain passage 76 is formed in the tool hook portion 74 of the fixing nut 70, the water that has flowed into the tool hook portion 74 flows out of the drain passage 76. Since the fixing nut 70 is screwed into the case-side screw portion 37 formed on the inner wall 36 of the housing portion in a state of entering the unit housing portion 35, the water that flows out from the water drainage passage 76 is not fixed to the fixing nut 70. Between the inner wall 36 and the accommodating portion inner wall 36, but the seal between the two is maintained by the O-ring 201 attached to the outer O-ring groove 78 of the fixing nut 70. For this reason, the water that flows between the fixing nut 70 and the inner wall 36 of the accommodating portion does not flow below the O-ring 201, and the portion where the fixing nut screw portion 73 and the case-side screw portion 37 are screwed together. The water flow is blocked by the O-ring 201.

  For this reason, the water that has flowed out of the drainage passage 76 of the tool hanging portion 74 flows on the main body attachment portion 50 of the main body case 30, but this water is directed toward the drainage portion 55 along the inclination of the inclined portion 56. Flowing. On the other hand, the diameter of the inner peripheral surface of the pedestal cover 60 is slightly larger than the outer diameter of the cover mounting portion 51 of the main body case 30, and the pedestal cover 60 attached to the cover mounting portion 51 has a counter. 1 apart. For this reason, the inclined portion 56 of the main body attachment portion 50 communicates with the drainage portion 55 and the gap between the pedestal cover 60 and the counter 1, and this communication path allows water on the main body attachment portion 50 to be counter 1. The drainage channel 215 drains upward. The water that flows in the direction of the drainage part 55 along the slope of the sloped part 56 is discharged onto the counter 1 through the drainage path 215.

  Further, since the space defined by the main body attaching portion 50, the cover attaching portion 51, and the pedestal cover 60 is reduced in volume by the protruding portion 67 of the pedestal cover 60, the water that can be stored in this space. The amount is decreasing. For this reason, it is difficult for water to collect on the main body attachment portion 50, and the water that has flowed on the main body attachment portion 50 is easily discharged from the drainage channel 215.

  In the fixing nut 70 according to this embodiment, since the drain passage 76 is formed in the tool hook portion 74, even when water flows into the tool hook portion 74, this water is passed through the drain passage 76. To the outside of the tool hook 74. Further, since the outer O-ring groove 78 is formed between the tool hook portion 74 and the fixed nut screw portion 73, the water discharged from the drainage passage 76 and the water flowing from the outside of the fixed nut screw portion 73. The O-ring 201 attached to the outer O-ring groove 78 can be prevented from flowing in the direction. As a result, both drainage and waterproofing can be achieved.

  Further, since an inner O-ring groove 79 is provided on the inner peripheral surface 72 of the fixing nut 70, when water flows into the tool hook 74, this water further flows in the axial direction of the fixing nut 70. The O-ring 202 attached to the inner O-ring groove 79 can be prevented from flowing in the direction opposite to the side where the tool hook 74 is located. As a result, drainage and waterproofness can be improved.

  Moreover, by improving drainage like these, it can suppress that rust, a bad smell, etc. generate | occur | produce due to water accumulating. As a result, the faucet device 5 can be comfortably used over a long period of time.

  Moreover, since water can be prevented from flowing in the direction of the fixed nut screw portion 73, rust and corrosion of the fixed nut screw portion 73 can be prevented. As a result, the screwed state of the fixing nut screw portion 73 can be maintained for a long time, and the durability of the fixing nut 70 and the apparatus using the fixing nut 70 when using the fixing nut 70 in an environment with much water is improved. be able to.

  Further, since the drainage performance is ensured by providing the drainage passage 76 in the tool hook portion 74, a dedicated tightening tool can be used to achieve both the securing of the drainage property of the fixing nut 70 and the tightening of the fixing nut screw portion 73. It can be tightened without using. As a result, an increase in manufacturing cost due to the provision of a dedicated tool can be prevented, and since it can be tightened with a commonly used tool, the ease of assembly can be ensured. .

  In addition, since a plurality of drainage passages 76 are formed in the tool hanging portion 74, water flowing into the tool hanging portion 74 is allowed to flow into any one of the drainage passages regardless of the direction of the fixing nut 70 after tightening. 76 can be drained. As a result, drainage can be improved more reliably.

  Moreover, since the communication part which connects the inner peripheral side and outer peripheral side of the tool hanging part 74 is provided by the notch-shaped drainage passage 76, a communication part can be provided easily. As a result, it is possible to suppress an increase in manufacturing cost when improving drainage.

  Further, in the faucet body 20 according to the above-described embodiment, the fixing nut screw portion 73 of the fixing nut 70 is screwed onto the case side screw portion 37 of the accommodating portion inner wall 36 in a state where the valve unit 80 is accommodated in the unit accommodating portion 35. As a result, the contact portion 77 of the fixing nut 70 is brought into contact with the valve unit 80, and the accommodation state of the valve unit 80 is maintained. As a result, even when water flows from above toward the valve unit 80 when the faucet body 20 is used, the water is drained from the drainage passage 76 of the fixing nut 70 and is attached to the outer O-ring groove 78. This water can be prevented from flowing in the direction of the valve unit 80 by the 201 and the O-ring 202 mounted in the inner O-ring groove 79. As a result, both drainage and waterproofing can be achieved.

  Further, since both drainage and waterproofing can be achieved in this way, when the water is prevented from flowing in the direction of the valve unit 80 from the lever 170 side, the entire fixing nut 70 is attached to the umbrella portion 173 of the lever 170 or the like. No need to cover and waterproof. As a result, the size of the periphery of the fixing nut 70 can be reduced, and the size of the faucet body 20 can be reduced.

  In the fixing nut 70 described above, the communication portion formed in the tool hook portion 74 is provided by the notched water drain passage 76, but the communication portion may be formed by other than the notch. For example, the communication portion may be provided by a hole communicating the inner peripheral side and the outer peripheral side of the tool hanging portion 74. The form of the communicating portion is not limited as long as the inner peripheral side and the outer peripheral side of the tool hooking portion 74 can communicate with each other.

  Further, the outer peripheral side seal portion forms an outer O-ring groove 78 in the fixed nut 70 so that the O-ring 201 can be mounted, and the inner peripheral side seal portion forms an inner O-ring groove 79 in the fixed nut 70 to form an O-ring. Although the ring 202 is provided by being attachable, the outer peripheral side seal portion and the inner peripheral side seal portion may be configured by other than these. For example, the outer peripheral side seal portion forms an O-ring groove on the accommodating portion inner wall 36 side and an O-ring is mounted on the accommodating portion inner wall 36 side, and the inner peripheral side seal portion forms an O-ring groove on the valve unit 80 side. Then, by mounting an O-ring on the valve unit 80 side, sealing performance may be secured between these O-rings. The outer peripheral side seal part and the inner peripheral side seal part may be in any form as long as the sealability at a desired position can be secured.

  Moreover, although the faucet body 20 described above is used in the faucet device 5 in which the water discharge unit 10 is installed at a position away from the faucet body 20, the faucet device 5 in which the faucet body 20 is used The thing other than the form mentioned above, such as a thing provided with a water discharge part in the vicinity of the faucet body 20, may be used.
