The protrusion 67 has a radius larger than the distance between the central axis of the tool hook 74 and the portion farthest from the central axis in the tool hook 74 having an inner diameter of the fixed nut 70. It is formed in a cylindrical shape whose outer diameter is slightly larger than the inner diameter of the cover mounting portion 51 provided.

  Thus, the protruding portion 67 formed in a cylindrical shape is provided on the flat surface portion 61 so that the central axis coincides with the central axis of the disk having the shape of the flat surface portion 61. Is lower than the height of the cover mounting portion 51 provided in the main body case 30. In addition, a part of the outer peripheral surface of the protruding portion 67 is formed in a flat shape, and this portion is a cover-side flat portion 68. When the pedestal cover 60 is attached to the cover attachment portion 51, the O-ring 203 is attached in a state of being attached to the O-ring groove 57 of the cover attachment portion 51.

  The faucet body 20 configured as described above is installed in the counter 1, and an installation hole 2 that penetrates the top plate of the counter 1 in the vertical direction is provided in a portion of the counter 1 where the faucet body 20 is installed. The faucet body 20 is formed and attached to the counter 1 using the installation hole 2. Specifically, the installation hole 2 has an inner diameter slightly larger than the outer diameter of the main body portion 31 of the main body case 30, and the faucet main body 20 has the main body mounting portion 50 of the main body case 30 on the upper surface of the counter 1. The main body portion 31 of the main body case 30 is inserted into the installation hole 2 in the orientation in which it is positioned.

  In this state, the mounting screw portion 32 of the main body 31 is located on the lower surface side of the counter 1, so that the mounting nut 195 is interposed between the mounting nut 190 and the counter 1 on the lower surface side of the counter 1. The top plate of the counter 1 is sandwiched between the main body mounting portion 50 and the mounting nut 190 by screwing 190 into the mounting screw portion 32. Accordingly, the faucet body 20 is installed on the counter 1.

  Further, the counter 1 is gently inclined in a direction in which the near side in a normal usage pattern when the faucet device 5 is used is slightly lower than the back side. When the faucet body 20 is installed on the counter 1, the faucet body 20 is installed in the direction in which the drainage portion 55 of the cover mounting portion 51 is located on the side where the relative height is lowered by the inclination of the counter 1. That is, the faucet body 20 is installed on the counter 1 in such a direction that the drainage portion 55 is positioned on the near side.

  The inflow pipe 181 and the outflow pipe 182 are connected to the faucet body 20 installed in the counter 1 in this way. Of these, two inflow pipes 181 are connected, one inflow pipe 181 is connected to a water supply pipe (not shown) at the other end, and the other inflow pipe 181 is a hot water device (not shown) at the other end. )It is connected to the. These two inflow pipes 181 are connected to two inflow holes 41 formed in the main body case 30. The outflow pipe 182 is connected to an outflow hole 42 formed in the main body case 30. Water and hot water flowing in from these inflow pipes 181 can also flow into the valve unit 80, and the valve unit 80 mixes fluids such as water and hot water that flow in from a plurality of flow paths to the outflow pipe 182. It is possible to flow in the direction of.

  The valve unit 80 according to this embodiment and the faucet device 5 in which the valve unit 80 is used are configured as described above, and the operation thereof will be described below. In the faucet device 5 including the valve unit 80 according to the present embodiment, the 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 is connected to the inflow pipe 181 side. By adjusting the flow rate of water or hot water flowing toward the outflow pipe 182 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. The lever shaft 90 has a spherical portion 91 and a bearing on the case side lever shaft support portion 111 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 112, and can move in the lever shaft support portion groove portion 112 with the operation of the lever 170.

  The lever shaft support groove portion 112 has an operation free portion 113 and an operation restriction portion 115, both of which are connected by a slide portion 114, so that the pin 92 also operates on the portion of the operation free portion 113. It is possible to be positioned at the portion of the restricting portion 115. First, the case where the pin 92 entering the lever shaft support portion groove 112 is positioned in the operation free portion 113 will be described. Since the pin 92 can move along the operation free portion 113, the lever 170 and The lever shaft 90 can be tilted in the direction in which the movement free portion 113 is formed with the central portion of the spherical portion 91 as the center. Further, the lever 170 and the lever shaft 90 can be tilted in the rotation direction around the central axis of the pin 92. Therefore, the lever 170 and the lever shaft 90 are supported so as to be tiltable in two directions, and are thus supported so as to be tiltable in all directions.

  Further, a portion of the lever shaft 90 on the lever shaft screw portion 98 side passes through the operation range limiting hole 116 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 116. That is, the lever shaft 90 can be tilted within a range in which the portion on the side where the lever shaft screw portion 98 is located is in contact with the operation range limiting hole 116. Further, since the operating range limiting hole 116 is formed in a direction in which the arc portion 118 is positioned on the rotation restricting hole 104 side of the case main body 101, the lever shaft 90 is not rotated when the lever shaft 90 is tilted. Tilt in a direction approaching 104. In contrast, when the lever shaft 90 is tilted, the portion of the lever shaft 90 on the spherical end 95 side tilts in a direction opposite to the direction in which the lever shaft screw portion 98 side tilts. For this reason, the portion on the spherical end 95 side of the lever shaft 90 that can be tilted within a range in which the portion on the lever shaft screw portion 98 abuts the operation range limiting hole 116 is in a neutral state, that is, the tilt angle is the case body. It can be tilted within a predetermined range in a direction away from a portion where the rotation restricting hole 104 of the case main body 101 is located from a state along the central axis of the portion 101 or the like.

  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.

  FIG. 42 is a cross-sectional view taken along the line RR in FIG. 7 and is an explanatory diagram showing the 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.

  FIG. 43 is an explanatory diagram in the case where the pin is located in the operation free portion of the lever shaft support portion groove portion. 44 is a cross-sectional view taken along the line S-S in FIG. 43. When the lever shaft 90 is in the neutral state, the water faucet device 5 is in a water-stopped state, but when the pin 92 of the lever shaft 90 is located in the operation free portion 113 of the lever shaft support portion groove portion 112. Adjusts the state of water discharge according to the tilt angle and tilt direction of the lever shaft 90. That is, when the pin 92 is located in the movement free portion 113 of the lever shaft support groove portion 112, the pin 92 can move along the movement free portion 113, so that the lever shaft 90 has a movement range. It is possible to tilt in any direction within a range where the operation is restricted by the restriction hole 116.

  For this reason, in the valve unit 80 according to the present embodiment, the water discharge amount increases as the tilt angle of the lever shaft 90 increases, and the water discharge amount decreases as the tilt angle decreases. Of the tilting direction of the lever shaft 90, the vicinity of one end of both ends of the arc portion 118 of the operation range limiting hole 116 is a high temperature position HP where the temperature of water discharge becomes the highest, and the other end Near the portion is a low temperature position LP where the temperature of the discharged water is lowest. For this reason, the temperature of the water discharge increases as the tilting direction of the lever shaft 90 approaches the high temperature position HP, and decreases as the temperature approaches the low temperature position LP.

  The water discharge amount and temperature are adjusted according to the inclination angle and direction of the lever shaft 90 as described above. The operation of each part at the time of this adjustment is based on the fact that the spherical end portion 95 is inserted into the shaft end insertion portion 136. This is done via a disc cap 130 that moves in response to the tilt of the shaft 90.

  FIG. 45 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. 46 is a cross-sectional view taken along the line TT in FIG. 45, 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 116, 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.

  In addition, when the pin 92 is positioned in the movement free portion 113, the lever shaft 90 can be tilted within a range in contact with the movement range restriction hole 116. The fan is open in the shape of a fan. For this reason, it is a range in which the lever shaft 90 can be tilted, and the limited operation range which is the operation range of the lever shaft 90 limited by the operation range limiting hole 116 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 restriction. It changes depending on the position of the lever shaft 90 on the operating range. The change in the temperature of the discharged water when the lever shaft 90 is tilted depends on the change in the flow rate from the cold water side inflow hole 156 and the hot water side inflow hole 157 to the disk side outflow hole 158 according to the horizontal position of the movable disk 140. Realized. For example, when the tilting position of the lever shaft 90 is the low temperature position LP, the flow rate from the cold water inflow hole 156 to the disk side outflow hole 158 is the largest, and when the tilting position of the lever shaft 90 is the high temperature position HP, The flow rate from the side inflow hole 157 to the disk side outflow hole 158 is the largest.

  FIG. 47 is a cross-sectional view taken along the line TT in FIG. 45, 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. 48 is a cross-sectional view taken along the line TT in FIG. 45, 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 limited operation range as described above. be able to. That is, by moving the movable disk 140 with the lever shaft 90 and changing the relative position between the movable disk 140 and the fixed disk 150 to operate the fluid mixing unit, the amount of water discharged and the temperature can be adjusted. At that time, the operation range restriction hole 116 restricts the operation range of the movable disc 140 by restricting the range in which the lever shaft 90 operates, and the movable disc 140 is within a range suitable for discharging water from the water outlet 15. That is, the amount of discharged water and the temperature can be adjusted by operating the fluid mixing unit.

  When the temperature and flow rate of the discharged water can be freely adjusted by tilting the lever shaft 90, the pin 92 of the lever shaft 90 is positioned at the operation free portion 113 of the lever shaft support groove portion 112 as described above. The lever shaft 90 is tilted by operating it in a desired state within the limited operation range. On the other hand, when restricting the state of water discharge, the pin 92 of the lever shaft 90 is positioned on the operation restricting portion 115.

  FIG. 49 is an explanatory diagram in the case where the pin is located in the operation restricting portion of the lever shaft support groove. 50 is a cross-sectional view taken along the line U-U in FIG. 49. Since the lever shaft support portion groove portion 112 into which the pin 92 of the lever shaft 90 is inserted is formed with a slide portion 114 that connects the operation free portion 113 and the operation restriction portion 115, the pin 92 is connected to the operation restriction portion 115. In the case of positioning, it is moved via the slide part 114. Specifically, in a state where the lever shaft 90 is in a neutral state and the pin 92 is positioned on the lower end side in the operation free portion 113, the lever shaft 90 is moved in a circumferential direction around the central axis of the unit case 100, Further, the pin 92 is rotated in the direction from the operation free portion 113 toward the operation restricting portion 115. When the pin 92 is rotated in this direction, the pin 92 moves in the slide portion 114 and comes into contact with a restriction portion side end portion 114b which is an end portion on the side where the operation restriction portion 115 is located. As a result, the lever shaft 90 cannot be rotated, but the state in which the lever shaft 90 cannot be rotated is the state in which the pin 92 is positioned in the operation restricting portion 115. As described above, the slide portion 114 is provided as a protruding portion moving portion that allows the pin 92 to move between the motion free portion 113 and the motion restricting portion 115.

  FIG. 51 is an explanatory diagram showing an operation in a state where the pin is located at the operation restricting portion. Since the movement restricting portion 115 has a length in the vertical direction that is approximately the same as the groove width of the lever shaft support groove portion 112, the pin 92 can easily come into contact with the contact portion 115a of the movement restricting portion 115. . When the pin 92 contacts the contact portion 115a, the tilt of the lever shaft 90 in this direction is restricted by the pin 92 and the operation restricting portion 115, and cannot be tilted. That is, the operation restricting unit 115 restricts the operation of the lever shaft 90 by restricting the movement of the pin 92 due to the operation of the lever shaft 90 in a predetermined direction within the restricted operation range.

  The movement restricting portion 115 is on a line connecting the vicinity of one end of the circular arc portion 118 of the movement range limiting hole 116 and the central axis of the first inner wall portion 109 and the like on the opposite side to the side where the circular arc portion 118 is located. Although formed, specifically, the operation restricting portion 115 is formed in a portion on the opposite side of the high temperature position HP. For this reason, when the pin 92 is positioned at the operation restricting portion 115 and the lever 92 cannot be tilted by the pin 92 coming into contact with the contact portion 115a, the lever shaft 90 is tilted in the direction of the high temperature position HP. Can not be. Therefore, in this case, only the hot water side inflow hole 157 and the disk side outflow hole 158 communicate with each other, and only hot water flowing from the hot water device into the faucet body 20 is discharged, so that the temperature of the discharged water becomes the highest. Cannot tilt the lever shaft 90. Thereby, water discharge only with hot water is controlled, and water discharge with the highest temperature cannot be performed. The operation restricting portion 115 is formed so as to be able to restrict the operation of the lever shaft 90 in the direction in which only hot water flows out of the restricted operation range.

  On the other hand, even when the pin 92 is positioned at the operation restricting portion 115, the lever shaft 90 can be tilted in the direction around the central axis of the pin 92. In this case, since the lever shaft 90 can be tilted in the direction of the low temperature position LP, only the water flowing into the faucet body 20 from the water supply pipe is discharged, so that the temperature of the discharged water becomes the lowest. The lever shaft 90 can be freely tilted. Thereby, water discharge of only water can be performed and water discharge with the lowest temperature can be performed.

  Further, when the temperature of discharged water can be freely adjusted in a state where the discharge of only hot water is restricted in this way, the pin 92 located in the operation restriction unit 115 is connected to the movement free portion. Move to 113. That is, the lever shaft 90 is in a neutral state, the lever shaft 90 is in a circumferential direction around the central axis of the unit case 100, and in a direction in which the pin 92 is directed from the operation restricting portion 115 to the operation free portion 113. Rotate. As a result, the pin 92 moves in the slide portion 114 and comes into contact with the free portion side end portion 114a which is the end portion on the side where the operation free portion 113 is located. As a result, the lever shaft 90 cannot be rotated, but the state in which the lever shaft 90 cannot be rotated in this way is the state where the pin 92 is positioned in the operation free portion 113. As described above, when the pin 92 is positioned at the operation free portion 113, the temperature and flow rate of the discharged water can be adjusted again by tilting the lever shaft 90 within the limited operation range.

  The valve unit 80 according to the present embodiment described above is provided with a pin 92 on the lever shaft 90 that can adjust the mixing ratio of water and hot water and the outflow amount of the mixed water, and the lever shaft into which the pin 92 is inserted. The support groove portion 112 is provided with a motion free portion 113, a motion restriction portion 115, and a slide portion 114 for connecting them. Thus, the lever shaft 90 can be freely tilted within the limited operation range by switching the position of the pin 92 in the lever shaft support portion groove portion 112 between the operation free portion 113 and the operation restriction portion 115. It is possible to restrict the tilting of the lever shaft 90 in a predetermined direction. Therefore, it is possible to create a state of restricting water discharge by simply providing the pin 92 and the lever shaft support groove portion 112 and changing the position of the pin 92 in the lever shaft support groove portion 112. As a result, the water discharge flow rate in a predetermined state can be regulated with a simple structure. Moreover, this can suppress an increase in manufacturing cost.

  Further, since the operation restricting portion 115 restricts the operation of the lever shaft 90 in the direction in which only hot water flows out of the restricted operation range, it is possible to prevent the hot water from being unnecessarily discharged. As a result, the utility cost during use of the faucet device 5 can be reduced.

  In the valve unit 80 described above, hot water is not discharged when the pin 92 is positioned at the operation restricting portion 115, but even when the pin 92 is positioned at the operation restricting portion 115, the operation restricting portion It is not necessary to completely stop water discharge in a state regulated by 115. For example, the movement restricting portion 115 has a groove length shorter than that of the movement free portion 113, so that even when the pin 92 is positioned at the movement restricting portion 115, the pin 92 extends along the movement restricting portion 115. It is possible to move within the range of the length of the operation restricting unit 115. Thereby, the lever shaft 90 can be tilted within a predetermined range as the pin 92 moves, and the maximum amount of operation of the lever shaft 90 in the restricting direction can be restricted. Therefore, the maximum amount can be set for water discharge in a predetermined mixed state of water and hot water.

  Further, in the valve unit 80 described above, the operation restricting portion 115 is provided so as to restrict the operation of the lever shaft 90 in the direction in which only hot water flows out, but the state restricted by the operation restricting portion 115 is other than this. It may be in the state.

  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.
