Both temperature and flow rate adjustment are achieved by changing the amount of communication between the water supply passage and the water inlet hole, the amount of communication between the hot water supply passage and the hot water inlet hole, and / or the amount of communication between the hot water outlet hole and the hot water outlet passage depending on the axial position and rotational position of the cylinder body.

Description

[Technical field]

[0001] The present invention relates to a faucet valve device, and more particularly to a faucet valve device suitable for achieving motorization of both temperature regulation and flow rate regulation. [Background technology]

[0002] The applicant of the present application has achieved motorization of a flow control valve (Patent Document 1). In this flow control valve, the rotation of a stepping motor is converted into linear movement of a pilot valve body by a lifter. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2017-201200 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, no suitable faucet valve device has yet been proposed that is suitable for achieving motorization of both temperature regulation and flow rate regulation.

[0005] The flow control valve of Patent Document 1 is suitable for motorizing flow control, but in order to adjust the temperature, it is necessary to control the two flow control valves independently, and there is a problem in that control becomes complicated in order to change the temperature without changing the flow rate, or to change the flow rate without changing the temperature.

[0006] The present invention has been devised under the above-mentioned background. An object of the present invention is to provide a faucet valve device suitable for realizing motorization of both temperature regulation and flow rate regulation. [Means for solving the problem]

[0007] The present invention includes a cylinder body formed in a hollow cylindrical shape, A water inlet hole, a hot water inlet hole, and a hot and cold water outlet hole are provided in the peripheral wall of the cylinder body, respectively; a housing body that accommodates the cylinder body so as to be axially movable and rotatable; a water supply passage, a hot water supply passage, and a hot and cold water outflow passage, each of which is provided so as to communicate with an internal space of the housing body; A first operating part that is rotatably provided on one axial side of the cylinder body; A second operating portion provided rotatably on the other axial side of the cylinder body; Equipped with The cylinder body is adapted to change a rotational position without changing an axial position by a rotational operation of the first operating part, and is adapted to change an axial position without changing a rotational position by a rotational operation of the second operating part, The amount of communication between the water supply passage and the water inlet hole, the amount of communication between the hot water supply passage and the hot water inlet hole, and / or the amount of communication between the hot water outlet hole and the hot water outlet passage are changed depending on the axial position and rotational position of the cylinder body, thereby realizing both temperature adjustment and flow rate adjustment. The present invention relates to a faucet valve device.

[0008] According to the present invention, since both temperature regulation and flow rate regulation are realized according to the axial position and rotational position of a common cylinder body, a compact faucet valve design can be realized. In addition, since there is no obstacle to the motorization of the first operating unit and the second operating unit, it is suitable for realizing the motorization of both temperature regulation and flow rate regulation.

[0009] In the present invention, for example, by rotating the first operating unit, the ratio of the amount of communication between the water supply channel and the water inlet hole and the amount of communication between the hot water supply channel and the hot water inlet hole changes, thereby realizing temperature adjustment, and by rotating the second operating unit, the total amount of communication, which is the sum of the amount of communication between the water supply channel and the water inlet hole and the amount of communication between the hot water supply channel and the hot water inlet hole, changes, thereby realizing flow rate adjustment.

[0010] Alternatively, conversely, flow rate adjustment may be realized by rotating the first operating unit to change the total communication amount, which is the sum of the communication amount between the water supply channel and the water inlet hole and the communication amount between the hot water supply channel and the hot water inlet hole, and temperature adjustment may be realized by rotating the second operating unit to change the ratio of the communication amount between the water supply channel and the water inlet hole and the communication amount between the hot water supply channel and the hot water inlet hole.

[0011] In addition, it is preferable that the first operating unit and the second operating unit can be rotated simultaneously, and when the first operating unit and the second operating unit are rotated simultaneously, the cylinder body changes its rotational position while changing its axial position.

[0012] According to this, by operating the first operating part and the second operating part simultaneously, it is possible to realize more rapid temperature adjustment and flow rate adjustment.

[0013] It is also preferable that the cylinder body is further provided with a shaft body whose rotational position is changed by rotational operation of the first operating part without changing the axial position, and whose axial position is changed by rotational operation of the second operating part without changing the rotational position, and the cylinder body is connected to the shaft body.

[0014] According to this, the control for changing the position of the cylinder body can be realized with a relatively simple configuration for controlling the position of the shaft body.

[0015] It is also preferable that the actuator further comprises a first connecting member that is connected or integrated with the shaft body and fixed in a rotational direction relative to the first operating part, and that the first connecting member is installed so as to be movable in the axial direction relative to the first operating part.

[0016] According to this, the rotational operation of the first operating part can be reliably transmitted as a rotational force of the shaft body, while the presence of the first connecting member does not impede the operation of the second operating part.

[0017] It is also preferable that the actuator further includes a direction changing member that converts the rotational operating force of the second operating part into an axial moving force, and a second connecting member that is connected to the shaft body and receives the axial moving force converted by the direction changing member, and that the shaft body is installed so as to be rotatable relative to the second connecting member.

[0018] According to this, the rotational operation of the second operating part can be reliably transmitted as the axial moving force of the shaft body, and the presence of the second connecting member does not impede the operation of the first operating part.

[0019] It is also preferable that the device further comprises a regulating member capable of adjusting the rotational range of the second operating portion as desired. According to this, the range of motion of the axial position of the cylinder body relative to the housing body can be adjusted by adjusting the rotational range of motion of the second operating part using the regulating member, so that the desired flow rate adjustment or temperature adjustment can be achieved even if there are individual variations in each part based on manufacturing tolerances, etc. Effect of the Invention

[0020] According to the present invention, since both temperature regulation and flow rate regulation are realized according to the axial position and rotational position of a common cylinder body, a compact faucet valve design can be realized. In addition, since there is no obstacle to the motorization of the first operating unit and the second operating unit, it is suitable for realizing the motorization of both temperature regulation and flow rate regulation.

FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0022] Next, a faucet valve device according to an embodiment of the present invention will be described with reference to the attached drawings. The faucet valve device 100 of this embodiment is a faucet valve device suitable for realizing motorization of both temperature regulation and flow rate regulation.

[0023] Fig. 1 is a schematic perspective view of a faucet valve device 100 according to one embodiment of the present invention, Fig. 2 is a schematic front view of the faucet valve device 100 of this embodiment, Fig. 3 is a schematic vertical cross-sectional perspective view of the faucet valve device 100 of this embodiment, and Fig. 4 is a schematic vertical cross-sectional view of the faucet valve device 100 of this embodiment. Also, Fig. 5 is an enlarged view of the cylinder body portion of Fig. 4, and Fig. 6 is a schematic perspective view showing the cylinder body 30 and shaft body 20 of this embodiment.

[0024] As shown in Figures 1 to 6, the faucet valve device 100 of this embodiment comprises a cylinder body 30 configured in a hollow cylindrical shape, and a housing body 10 that accommodates the cylinder body 30 so that it can move axially and rotate.

[0025] [Cylinder body 30] The cylinder body 30 has, for example, an outer diameter of 15 mm, a wall thickness of 0.5 mm, and an axial length of 50 mm, and is made of stainless steel. When the cylinder body 30 is made of a resin material, it is preferable to make the wall thicker.

[0026] With particular reference to FIG. 5, a right end wall 31 made of resin is fitted to the right end of the cylinder body 30, and a left end wall 32 made of resin is fitted to the left end of the cylinder body 30.

[0027] A substantially rectangular water inlet hole 34 is provided in the right region of the peripheral wall 33 of the cylinder body 30. The water inlet hole 34 opens, for example, at a circumferential angle (angle measured around the axis) of 0° (which is used as the basis for the following explanation of angular positions) to 90°, and is formed in an area a certain distance from the right end of the cylinder body 30 in the axial direction.

[0028] A substantially rectangular molten metal inlet hole 35 is provided in the left region of the peripheral wall 33 of the cylinder body 30. The molten metal inlet hole 35 opens, for example, at a circumferential angle (angle measured around the axis) of 90° to 180° (i.e., opens at an angular position different from that of the water inlet hole 34) and is formed in an area a certain distance from the left end of the cylinder body 30 in the axial direction.

[0029] A hot and cold water outlet hole 36 is provided in the peripheral wall 33 of the cylinder body 30 in an approximately central region in the axial direction.

[0030] Moreover, the cylinder body 30 of this embodiment has a central pipe portion 37 extending from the right end wall 31 to the left end wall 32. A partition wall 38 extending radially outward from the central pipe portion 37 is provided at an axial position corresponding to the hot and cold water outlet hole 36 of the cylinder body 30 (see also FIG. 6).

[0031] [Shaft body 20] The shaft body 20 is inserted into the central tube portion 37 and fixed to the right end wall 31 and the left end wall 32. This allows the shaft body 20 and the cylinder body 30 to rotate together and move axially together. The shaft body 20 has a diameter of, for example, φ3 and is made of stainless steel.

[0032] [Housing body 10] The internal space of the housing body 10 that accommodates the cylinder body 30 is, for example, a cylindrical space, and a gap is provided between the cylinder body 30 and the peripheral wall 33. The housing body 10 is also made of stainless steel. Meanwhile, the exterior of the housing body 10 is generally rectangular prism-shaped, and is made of PPS resin.

[0033] 4 and 5 in particular, the left end of the internal space of the housing body 10 is defined by a left side cover member 47. The left side cover member 47 is a generally disk-shaped member, and is fitted into the inner peripheral step surface of the housing body 10 via an O-ring 47a. A through hole through which the shaft body 20 is inserted is provided in the center of the left side cover member 47. The through hole is sealed by an X-ring 47b while allowing the shaft body 20 to rotate and move axially.

[0034] Similarly, the right end of the internal space of the housing body 10 is defined by a right cover member 57. The right cover member 57 is a generally disk-shaped member, and is fitted into the inner peripheral step surface of the housing body 10 via an O-ring 57a. A through hole through which the shaft body 20 is inserted is provided in the center of the right cover member 57. The through hole is sealed by an X-ring 57b while allowing the shaft body 20 to rotate and move in the axial direction.

[0035] The housing body 10 is provided with a water supply passage, a hot water supply passage, and a hot and cold water outflow passage, which are in communication with the internal space thereof.

[0036] Specifically, the hot and cold water outlet path in this embodiment is provided by a hot and cold water outlet 15 that is integral with the housing body 10. The hot and cold water outlet 15 opens toward the top of the housing body 10 and is connected to a hot and cold water supply pipe 63 via an elbow connection pipe 62, for example.

[0037] In addition, the hot and cold water outlet 15 is provided at a size and position that allows all of the hot and cold water outlet holes 36 of the cylinder body 30 to communicate with each other regardless of the position or posture of the cylinder body 30 within the movable range.

[0038] Meanwhile, the water supply passage of this embodiment is provided by a water supply pipe 11 that is removable from the housing body 10, and a water-side communication hole 12 that communicates the inside of the water supply pipe 11 with the internal space of the housing body 10. The water supply pipe 11 is fitted via an O-ring into a connection port 11r provided on the lower surface of the housing body 10. The water-side communication hole 12 has a circular cross-sectional hole on the water supply pipe 11 side, and a rectangular cross-sectional hole that fits within the circular cross section on the internal space side of the housing body 10 side.

[0039] Similarly, the hot water supply path in this embodiment is provided by a hot water supply pipe 13 that is removable from the housing body 10, and a hot water side communication hole 14 that communicates the inside of the hot water supply pipe 13 with the internal space of the housing body 10. As with the water supply pipe 11, the hot water supply pipe 13 is fitted into a connection port 13r provided on the lower surface of the housing body 10 via an O-ring. As with the water side communication hole 12, the hot water side communication hole 14 is also a circular cross-sectional hole on the hot water supply pipe 13 side, and a rectangular cross-sectional hole that fits within the circular cross section on the internal space side of the housing body 10.

[0040] [Secondary pipe members 16, 18] The lower side (one example of one side) of water side auxiliary pipe member 16 is accommodated inside water side communication hole 12. Water side auxiliary pipe member 16 is capable of sliding upward or downward inside water side communication hole 12 depending on the water pressure difference between its lower side and upper side (one example of the other side). Specifically, a packing 17 (water side seal member) is interposed between water side communication hole 12 and water side auxiliary pipe member 16, and said packing 17 holds water side auxiliary pipe member 16 so that it can slide upward or downward relative to water side communication hole 12. When water side auxiliary pipe member 16 moves upward, the upper side (one example of the other side) of water side auxiliary pipe member 16 can abut against peripheral wall 33 of cylinder body 30 and can communicate with water inlet hole 34.

[0041] FIG. 7 is a schematic perspective view of the water side auxiliary pipe member 16 of this embodiment. As shown in FIG. 7, the water side auxiliary pipe member 16 of this embodiment has a flange portion 16f as a water side movement restricting portion that restricts the stroke of sliding movement relative to the inside of the water side communicating hole 12. The flange portion 16f is accommodated in the circular cross-sectional hole on the water supply pipe 11 side of the water side communicating hole 12, and is sized so that it cannot be inserted into the rectangular cross-sectional hole of the water side communicating hole 12, and the flange portion 16f abuts against it to restrict the amount of movement of the water side auxiliary pipe member 16. In this embodiment, the stroke of the sliding movement of the water side auxiliary pipe member 16 is 1 mm. In addition, the water side auxiliary pipe member 16 has a groove portion 16g for fitting the packing 17.

[0042] As shown in Fig. 7, the upper surface 16r of the water side auxiliary pipe member 16 is part of a cylindrical surface with a radius of curvature of 10 mm (preferably in the range of 5 mm to 15 mm) at the time of shipment (before use). That is, the radius of curvature is slightly larger than the radius of curvature (8.5 mm) of the peripheral wall 33 of the cylinder body 30. This prevents a state in which only both ends of the upper surface 16r of the water side auxiliary pipe member 16 in the arc-shaped direction come into contact with the cylinder body 30 (a state that can occur when the relationship between the radii of curvature is reversed). In other words, a state in which the center of the upper surface 16r of the water side auxiliary pipe member 16 in the arc-shaped direction comes into contact with the cylinder body 30 is ensured, and the degree of close contact between the upper surface 16r of the water side auxiliary pipe member 16 and the cylinder body 30 is improved.

[0043] Furthermore, the hardness (at least of the upper surface) of the water side auxiliary pipe member 16 is smaller than the hardness of the peripheral wall 33 of the cylinder body 30. This prevents undesired wear of the peripheral wall 33 of the cylinder body 30, while the upper surface 16r of the water side auxiliary pipe member 16 is expected to wear in accordance with the peripheral wall 33 of the cylinder body 30, which is preferable for the adhesion performance between the upper surface 16r of the water side auxiliary pipe member 16 and the cylinder body 30. On the other hand, since the amount of movement is restricted by the flange portion 16f serving as the water side movement restricting portion, excessive wear can also be restricted.

[0044] The hardness is determined, for example, by the Vickers hardness obtained by a test specified in ISO 6507 (JIS Z 2244). The water side auxiliary pipe member 16 of this embodiment is made of polyacetal resin, and has a significantly lower hardness than the peripheral wall 33 of the cylinder body 30, which is made of stainless steel.

[0045] The size and position (in the axial direction of the housing body 10) of the pipe hole 16h of the water side auxiliary pipe member 16 are such that they can communicate with the entire water inlet hole 34 while being controlled to maximize the amount of communication between the water side auxiliary pipe member 16 and the water inlet hole 34 (see Figures 9 and 10 described below).

[0046] Similarly, the lower side (an example of one side) of the hot water side auxiliary pipe member 18 is accommodated inside the hot water side communication hole 14. The hot water side auxiliary pipe member 18 is capable of sliding upward or downward inside the hot water side communication hole 14 according to the water pressure difference between its lower side and upper side (an example of the other side). Specifically, a packing 19 (hot water side seal member) is interposed between the hot water side communication hole 14 and the hot water side auxiliary pipe member 18, and the packing 19 holds the hot water side auxiliary pipe member 18 so that it can slide upward or downward relative to the hot water side communication hole 14. When the hot water side auxiliary pipe member 18 moves upward, the upper side (an example of the other side) of the hot water side auxiliary pipe member 18 can abut against the peripheral wall 33 of the cylinder body 30, and can communicate with the hot water inlet hole 35.

[0047] Fig. 7 is also a schematic perspective view of the hot water side auxiliary pipe member 18 of this embodiment. As shown in Fig. 7, the hot water side auxiliary pipe member 18 of this embodiment also has a flange portion 18f as a hot water side movement restricting portion that restricts the stroke of sliding movement relative to the inside of the hot water side communication hole 14. The flange portion 18f is accommodated in the circular cross-sectional hole on the hot water supply pipe 13 side of the hot water side communication hole 14, and is sized so that it cannot be inserted into the rectangular cross-sectional hole of the hot water side communication hole 14, and the flange portion 18f abuts against it to restrict the movement amount of the hot water side auxiliary pipe member 18. In this embodiment, the stroke of sliding movement of the hot water side auxiliary pipe member 18 is 5 mm. The hot water side auxiliary pipe member 18 also has a groove portion 18g for fitting the packing 19.

[0048] As shown in Fig. 7, the upper surface 18r of the hot water side auxiliary pipe member 18 also becomes part of a cylindrical surface with a radius of curvature of 10 mm (preferably in the range of 5 mm to 15 mm) at the time of shipment (before use). That is, the radius of curvature is slightly larger than the radius of curvature (8.5 mm) of the peripheral wall 33 of the cylinder body 30. This prevents a state in which only both ends in the arc-shaped direction of the upper surface 18r of the hot water side auxiliary pipe member 18 come into contact with the cylinder body 30 (a state that can occur when the relationship between the radii of curvature is reversed). In other words, a state in which the center in the arc-shaped direction of the upper surface 18r of the hot water side auxiliary pipe member 18 comes into contact with the cylinder body 30 is ensured, and the degree of close contact between the upper surface 18r of the hot water side auxiliary pipe member 18 and the cylinder body 30 is improved.

[0049] Furthermore, the hardness (at least of the upper surface) of the hot water side auxiliary pipe member 18 is also smaller than the hardness of the peripheral wall 33 of the cylinder body 30. This prevents the peripheral wall 33 of the cylinder body 30 from being undesirably worn, while the upper surface 18r of the hot water side auxiliary pipe member 18 is expected to wear in accordance with the peripheral wall 33 of the cylinder body 30, which is preferable for the adhesion performance between the upper surface 18r of the hot water side auxiliary pipe member 18 and the cylinder body 30. On the other hand, since the amount of movement is restricted by the flange portion 18f serving as a hot water side movement restricting portion, it is also possible to prevent unnecessary wear.

[0050] The molten metal side auxiliary pipe member 18 of this embodiment is also made of polyacetal resin, and has a hardness significantly smaller than that of the peripheral wall 33 of the cylinder body 30, which is made of stainless steel.

[0051] The size and position (in the axial direction of the housing body 10) of the pipe hole 18h of the molten metal side auxiliary pipe member 18 are controlled so that the amount of communication between the molten metal side auxiliary pipe member 18 and the molten metal inlet hole 35 is maximized, and the size and position are such that the pipe hole 18h can communicate with the entire molten metal inlet hole 35 (see Figures 9 and 10 described later).

[0052] [First operating mechanism 40] 1 to 4, a first operating mechanism 40 is provided on the left side (one axial side) of the cylinder body 30. The first operating mechanism 40 has a first operating part 41 that is provided so as to be rotatable. In this embodiment, the first operating part 41 is a stepping motor that receives a control command from a control main body (not shown) and can be rotated by the control command.

[0053] In this embodiment, the shaft body 20 and the cylinder body 30 are adapted to change their rotational positions by rotating the first operating portion 41 without changing their axial positions.

[0054] 4, a rotating shaft (output shaft) 41s of the first operating unit 41 is fixed to the bottom of the rotating cylinder 42 in both the axial direction and the rotational direction. The rotating cylinder 42 is disposed so that its bottom is located on the left side, and is held within the housing cylinder 45 so as to be rotatable about its axis.

[0055] The left side of the cylindrical housing 45 also holds the main body of the first operating part 41 (at a position near the rotation shaft 41s) via a retaining ring 44. The right side of the cylindrical housing 45 is connected (fitted) to the left end of the housing body 10 and a left cover member 47 via a connecting ring 46. A resin sliding bearing (bush) 46b for inserting the shaft body 20 is provided in the center of the connecting ring 46 (see FIG. 5).

[0056] The right side (opposite the bottom) of the rotating cylinder 42 is open, and the sliding cylinder 43 is fitted therein so as to be slidable in the axial direction, and the rotating cylinder 42 and the sliding cylinder 43 are fixed in the rotation direction. For example, the sliding cylinder 43 has four convex parts that protrude in a cross shape in the axial cross section, and the rotating cylinder 42 has four concave parts that accommodate the four convex parts so as to be slidable in the axial direction. That is, each of the four convex parts is accommodated in each of the four concave parts, and when the rotating cylinder 42 rotates, the sliding cylinder 43 also rotates in the same manner. When the sliding cylinder 43 rotates, the shaft body 20 and the cylinder body 30 also rotate in the same manner. On the other hand, the sliding cylinder 43 is accommodated in the rotating cylinder 42 without being fixed in the axial direction. That is, even if the shaft body 20 moves in the axial direction, the rotating cylinder 42 is prevented from moving in the axial direction, or the rotating cylinder 42 rotates idly without applying a force in the axial direction. (Therefore, even if the operating force of the second operating part 51 described later is relatively small, the shaft body 20 and the cylinder body 30 can be moved sufficiently in the axial direction.)

[0057] The sliding cylinder 43 is fixed to the left end of the shaft body 20. As a result, the sliding cylinder 43 is fixed in the rotational direction relative to the rotation shaft 41s of the first operating part 41 as a first connecting member, while being movable in the axial direction relative to the rotation shaft 41s of the first operating part 41.

[0058] In this embodiment, the first operating portion 41 provides a rotation operation of up to 90°+α.

[0059] [Second operating mechanism 50] On the other hand, a second operation mechanism 50 is provided on the right side (the other axial side) of the cylinder body 30. The second operation mechanism 50 has a second operation part 51 that is provided so as to be rotatable. In this embodiment, the second operation part 51 is also a stepping motor that receives a control command wirelessly from a control main body part (not shown) and can be rotated by the control command.

[0060] In this embodiment, the shaft body 20 and the cylinder body 30 are adapted to change their axial positions by rotating the second operating portion 51 without changing their rotational positions.

[0061] 4, the rotating shaft (output shaft) 51s of the second operating unit 51 is fixed to the bottom of the rotating cylinder 52 in both the axial direction and the rotational direction. The rotating cylinder 42 is disposed so that its bottom is located on the right side, and is held within the housing cylinder 55 so as to be rotatable about its axis.

[0062] The right side of the housing cylinder 55 also holds the main body of the second operation part 51 (at a position near the rotation shaft 51s) via a retaining ring 54. The left side of the housing cylinder 55 is connected (fitted) to the right end of the housing body 10 and a right cover member 57 via a connecting ring 56. A resin sliding bearing (bush) 56b for inserting the shaft body 20 is also provided in the center of the connecting ring 56 (see FIG. 5).

[0063] Inside the rotating cylinder 52, a space corresponding to the trapezoidal two-thread female thread of pitch 16 is formed, and the left side (opposite to the bottom) is open. A screw body 53 corresponding to the trapezoidal two-thread male thread of pitch 16 is screwed into the space. The left end of the screw body 53 is located further left than the left end of the rotating cylinder 52, and has a protrusion 53p (e.g., two places, top and bottom) that protrudes into axial grooves 55g and 56g (e.g., two places, top and bottom) provided on the inner surface of the housing cylinder 55 (and the inner surface of the cylindrical part of the connection ring 56 in this embodiment), and is slidable in the axial direction within the axial grooves 55g and 56g. As a result, when the output shaft 51s of the second operating part 51 rotates, the rotating cylinder 52 also rotates, and the screw body 53 moves in the axial direction due to the screwing of the inner space of the rotating cylinder 52 with the screw body 53 and the engagement of the axial grooves 55g and 56g with the protrusion 53p.

[0064] The threaded body 53 holds the right end of the shaft body 20 via a pair of retaining rings 58. As a result, the threaded body 53 and the shaft body 20 are rotatable relative to each other, but are fixed in the axial direction, and the shaft body 20 moves in the axial direction due to the axial movement of the threaded body 53. That is, the shaft body 20 is stored in the rotating cylinder 52 in a state in which it can rotate relative to the threaded body 53, and even if the shaft body 20 rotates, the threaded body 53 is prevented from rotating in the same manner, or the threaded body 53 rotates idly without applying force in the rotational direction to the threaded body 53. (Therefore, even if the operating force of the first operating part 41 described above is relatively small, the shaft body 20 and the cylinder body 30 can be sufficiently rotated.)

[0065] With the above configuration, the rotating cylinder 52 (the space corresponding to the trapezoidal two-thread female thread) serves as a direction changing member to convert the rotational operating force of the second operating part 51 into an axial moving force, and the screw-type body 53 and the retaining ring 58 serve as a second connecting member to receive the axial moving force converted by the rotating cylinder 52.

[0066] In this embodiment, the second operating portion 51 provides a rotational operation of up to about 150°, so that the shaft body 20 (and the cylinder body 30) has a movement stroke of about 6.0 mm in the axial direction.

[0067] [Regulation member for second operation section] The faucet valve device 100 of this embodiment further includes a restricting member capable of adjusting as desired the rotational range of the second operating part 51. Specifically, as shown in Fig. 8, a protruding region 54p provided on the inner peripheral surface of the retaining ring 54 functions as a restricting member to obstruct a part of the rotational orbit of a stopper 52s provided on the outer peripheral surface of the rotating cylinder 52, thereby making it possible to adjust the rotational range of the rotating cylinder 52 (i.e., the rotational range of the second operating part).

[0068] Fig. 8(a) is a side view of the protruding region 54p provided on the inner peripheral surface of the retaining ring 54, as viewed from the inside, and Fig. 8(b) and Fig. 8(c) are perspective views of the protruding region 54p, as viewed from the inside. As shown in Fig. 8(a) to Fig. 8(c), in this embodiment, the protruding region 54p extends over approximately 210°, so that the rotational range of the rotating barrel 52 (i.e., the rotational range of the second operating part) is restricted to approximately 150°.

[0069] The fixed position of the retaining ring 54 relative to the housing cylinder 55 can be manually adjusted in the circumferential direction by utilizing the long hole 54h. This allows the rotational range of the rotating cylinder 52 (i.e., the rotational range of the second operating part 51) to be adjusted so as to match the desired axial range of the shaft body 20 (and the cylinder body 30). In other words, the adjustment of the axial range of the shaft body 20 and the cylinder body 30 relative to the housing body 10 can be realized by adjusting the rotational range of the second operating part 51 by adjusting the fixed position of the retaining ring 54 (regulating member). Therefore, even if there is individual variation in each part based on manufacturing tolerances, etc., the desired flow rate adjustment or temperature adjustment described later can be realized with high precision.

[0070] [Both ends of shaft body 20] Due to the above-mentioned configuration, both ends of the shaft body 20 in this embodiment are located within an area that is blocked off so as not to communicate with the internal space of the housing body 10, and are open to the atmosphere (receive atmospheric pressure rather than water pressure).

[0071] Specifically, the left end of shaft body 20 is blocked off from communication with the internal space of housing body 10 by a resin sliding bearing (bush) 46b and an X-ring 47b, and the right end of shaft body 20 is blocked off from communication with the internal space of housing body 10 by a resin sliding bearing (bush) 56b and an X-ring 57b.

[0072] This significantly reduces the effect of water pressure in the internal space of the housing body 10 on the shaft body 20. This reduces the torque (force) required to rotate or axially move the shaft body 20 (and the cylinder body 30), i.e., reduces the torque required for each of the first operating part 41 and the second operating part 51. It is even better if the diameters of the blocked parts of the shaft body 20 are the same.

[0073] Furthermore, both ends of the shaft body 20 are maintained in an atmosphere-open state even if the axial position of the shaft body 20 is changed by rotating the second operating part 51. This allows only small torque to be required for each of the first operating part 41 and the second operating part 51 even if the axial position of the shaft body 20 is changed.

[0074] In addition, the housing body 10 has a left side cover member 47 and a right side cover member 57 to divide the internal space, and by removing these cover members 47, 57, the internal parts of the housing body 10 can be easily assembled or disassembled (e.g., for maintenance, etc.).

[0075] Furthermore, in this embodiment, each of the cover members 47, 57 of the housing body 10 is located inward from the axial end portion of the housing body 10, thereby reducing the length of the shaft body 20.

[0076] [Water stop function] The faucet valve device 100 of this embodiment further includes a hot and cold water stopper that stops the flow of hot and cold water. Even if the cylinder body 30 does not have perfect sealing performance in order to minimize the sliding resistance of the cylinder body 30 and reduce the operating torque required for flow rate adjustment and temperature adjustment, a separate hot and cold water stopper can be provided to ensure reliable water stoppage.

[0077] Specifically, the hot and cold water stopper has a cold water stopper 11s provided on the upstream side of the water supply passage and a hot water stopper 13s provided on the upstream side of the hot water supply passage (see FIG. 2). This prevents hot water or cold water from flowing back to the other upstream side.

[0078] [Function of the faucet valve device 100] Next, the operation of the faucet valve device 100 of this embodiment will be described.

[0079] Due to the above-mentioned configuration, the cylinder body 30 of this embodiment is configured to change the rotational position without changing the axial position by rotating the first operating part 41, while it is configured to change the axial position without changing the rotational position by rotating the second operating part 51.

[0080] Then, the amount of communication between the water side auxiliary pipe member 16 (water supply passage) and the water inlet hole 34, and the amount of communication between the hot water side auxiliary pipe member 18 (hot water supply passage) and the hot water inlet hole 35 change depending on the axial position and rotational position of the cylinder body 30, thereby realizing both temperature adjustment and flow rate adjustment. In this embodiment, the hot and cold water outlet hole 36 and the hot and cold water outlet passage are always maintained in a good state of communication. Figure 9 is a schematic diagram showing the state in which the water side auxiliary pipe member 16 and the hot water side auxiliary pipe member 18 of this embodiment abut against the cylinder body 30.

[0081] In this embodiment, the temperature can be adjusted by rotating the first operating part 41 to change the ratio of the amount of communication between the water side auxiliary pipe member 16 (water supply path) and the water inlet hole 34 and the amount of communication between the hot water side auxiliary pipe member 18 (hot water supply path) and the hot water inlet hole 35. The flow rate can be adjusted by rotating the second operating part 51 to change the total amount of communication, which is the sum of the amount of communication between the water side auxiliary pipe member 16 (water supply path) and the water inlet hole 34 and the amount of communication between the hot water side auxiliary pipe member 18 (hot water supply path) and the hot water inlet hole 35.

[0082] 10 is a schematic explanatory diagram of the position control of the cylinder body 30 in this embodiment. In this embodiment, the temperature is adjusted according to the rotational position of the cylinder body 30, and the flow rate is adjusted according to the axial position of the cylinder body 30.

[0083] FIG. 10( a ) shows the positions of the water inlet hole 34 and the hot water inlet hole 35 in the peripheral wall 33 of the cylinder body 30 .

[0084] Fig. 10(b) shows a schematic diagram of a state in which the communication between the water-side auxiliary pipe member 16 (hot water / water supply passage) and the water inlet hole 34 is at a maximum, and the communication between the hot water-side auxiliary pipe member 18 (hot water supply passage) and the hot water inlet hole 35 is blocked. At this time, the hot water / water mixture output through the hot water / water outlet hole 36 and the hot water / water outlet passage is 100% water and 0% hot water (the flow rate is 100%).

[0085] Figure 10(c) shows a schematic state in which the shaft body 20 and cylinder body 30 have changed rotational positions by rotating the first operating part 41 from the state shown in Figure 10(b), so that the communication between the water side auxiliary pipe member 16 (water supply path) and the water inlet hole 34 is 50%, and the communication between the hot water side auxiliary pipe member 18 (hot water supply path) and the hot water inlet hole 35 is also 50%. At this time, the hot and cold water mixture output via the hot and cold water outlet hole 36 and the hot and cold water outlet path is 50% water and 50% hot water (the flow rate is 100%).

[0086] Figure 10(d) shows a schematic diagram of a state in which the shaft body 20 and cylinder body 30 have changed their rotational positions by further rotating the first operating part 41 from the state shown in Figure 10(c), blocking communication between the water side auxiliary pipe member 16 (water supply path) and the water inlet hole 34, and maximizing communication between the hot water side auxiliary pipe member 18 (hot water supply path) and the hot water inlet hole 35. At this time, the hot and cold water mixture output via the hot and cold water outlet hole 36 and the hot and cold water outlet path is 0% water and 100% hot water (the flow rate is 100%).

[0087] Figure 10(e) shows a schematic state in which the shaft body 20 and cylinder body 30 have changed their rotational positions by further rotating the first operating part 41 from the state shown in Figure 10(c), so that the communication between the water side auxiliary pipe member 16 (water supply path) and the water inlet hole 34 is 45%, and the communication between the hot water side auxiliary pipe member 18 (hot water supply path) and the hot water inlet hole 35 is 55%. At this time, the hot and cold water mixture output via the hot and cold water outlet hole 36 and the hot and cold water outlet path is 45% water and 55% hot water (the flow rate is 100%).

[0088] Figure 10(f) shows a schematic state in which the axial position of the shaft body 20 and the cylinder body 30 has been changed by further rotating the second operating part 51 from the state shown in Figure 10(e), so that the communication amount between the water side auxiliary pipe member 16 (water supply path) and the water inlet hole 34 is 22.5%, and the communication amount between the hot water side auxiliary pipe member 18 (hot water supply path) and the hot water inlet hole 35 is 27.5%. At this time, the hot and cold water mixture output through the hot and cold water outlet hole 36 and the hot and cold water outlet path is 45% water and 55% hot water, but the flow rate is 50%.

[0089] Figure 10(g) shows a schematic state in which the axial position of the shaft body 20 and the cylinder body 30 has been changed by further rotating the second operating part 51 from the state shown in Figure 10(f), blocking communication between the water side auxiliary pipe member 16 (water supply path) and the water inlet hole 34, and also blocking communication between the hot water side auxiliary pipe member 18 (hot water supply path) and the hot water inlet hole 35. At this time, the hot and cold water mixture output via the hot and cold water outlet hole 36 and the hot and cold water outlet path is 0% water and 0% hot water (i.e., the flow rate is 0%).

[0090] As shown in Figures 10(a) to 10(g), in this embodiment, by rotating the first operating unit 41, the ratio of the amount of communication between the water side auxiliary pipe member 16 (water supply passage) and the water inlet hole 34 and the amount of communication between the hot water side auxiliary pipe member 18 (hot water supply passage) and the hot water inlet hole 35 changes, thereby realizing temperature adjustment, and by rotating the second operating unit 51, the total amount of communication, which is the sum of the amount of communication between the water side auxiliary pipe member 16 (water supply passage) and the water inlet hole 34 and the amount of communication between the hot water side auxiliary pipe member 18 (hot water supply passage) and the hot water inlet hole 35, changes, thereby realizing flow rate adjustment.

[0091] The first operating unit 41 and the second operating unit 51 can be rotated simultaneously. When the first operating unit 41 and the second operating unit 51 are rotated simultaneously, the shaft body 20 and the cylinder body 30 change their rotational positions while changing their axial positions. Thus, by operating the first operating unit 41 and the second operating unit 51 simultaneously, it is possible to achieve faster temperature adjustment and flow rate adjustment.

[0092] [Variations] In the above-described embodiment, it is also possible to switch the functions of the first operating part 41 and the second operating part 51, for example, by changing the positions of the water inlet hole 34 and the hot water inlet hole 35. That is, the rotation of the first operating part 41 may change the total communication amount, which is the sum of the communication amount between the water side auxiliary pipe member 16 (water supply path) and the water inlet hole 34 and the communication amount between the hot water side auxiliary pipe member 18 (hot water supply path) and the hot water inlet hole 35, to adjust the flow rate, and the rotation of the second operating part 51 may change the ratio of the communication amount between the water side auxiliary pipe member 16 (water supply path) and the water inlet hole 34 and the communication amount between the hot water side auxiliary pipe member 18 (hot water supply path) and the hot water inlet hole 35 to adjust the temperature.

[0093] In such a modified example, for example, the water inlet hole 34 opens at a circumferential angle (angle measured around the axis) of 0° to 90°, and is formed in an area a certain distance from the right end of the cylinder body 30 in the axial direction.

[0094] For example, the hot water inlet hole 35 opens at a circumferential angle (angle measured around the axis) of 0° to 90° (i.e., opens at the same angular position as the water inlet hole 34) and is formed in an area a certain distance in the axial direction from the left end of the cylinder body 30.

[0095] 11 is a schematic explanatory diagram of the position control of the cylinder body 30 in such a modified example. In this modified example, the temperature is adjusted according to the axial position of the cylinder body 30, and the flow rate is adjusted according to the rotational position of the cylinder body 30.

[0096] FIG. 11( a ) shows the positions of the water inlet hole 34 and the hot water inlet hole 35 in the peripheral wall 33 of the cylinder body 30 .

[0097] 11(b) shows a schematic diagram of a state in which the amount of communication between the water-side auxiliary pipe member 16 (water supply passage) and the water inlet hole 34 is at a maximum, and the communication between the hot water-side auxiliary pipe member 18 (hot water supply passage) and the hot water inlet hole 35 is blocked. At this time, the hot and cold water mixture output through the hot and cold water outlet hole 36 and the hot and cold water outlet passage is 100% water and 0% hot water (the flow rate is 100%).

[0098] Figure 11(c) shows a schematic state in which the axial position of the shaft body 20 and the cylinder body 30 has been changed by rotating the second operating part 51 from the state shown in Figure 11(b), so that the communication between the water side auxiliary pipe member 16 (water supply path) and the water inlet hole 34 is 50%, and the communication between the hot water side auxiliary pipe member 18 (hot water supply path) and the hot water inlet hole 35 is also 50%. At this time, the hot and cold water mixture output via the hot and cold water outlet hole 36 and the hot and cold water outlet path is 50% water and 50% hot water (the flow rate is 100%).

[0099] Figure 11(d) shows a schematic diagram of a state in which the shaft body 20 and cylinder body 30 have changed their axial positions by further rotating the second operating part 51 from the state shown in Figure 11(c), blocking communication between the water side auxiliary pipe member 16 (water supply path) and the water inlet hole 34, and maximizing communication between the hot water side auxiliary pipe member 18 (hot water supply path) and the hot water inlet hole 35. At this time, the hot and cold water mixture output via the hot and cold water outlet hole 36 and the hot and cold water outlet path is 0% water and 100% hot water (the flow rate is 100%).

[0100] Figure 11(e) shows a schematic state in which the axial position of the shaft body 20 and the cylinder body 30 has been changed by further rotating the second operating part 51 from the state shown in Figure 11(c), so that the communication amount between the water side auxiliary pipe member 16 (water supply path) and the water inlet hole 34 is 45%, and the communication amount between the hot water side auxiliary pipe member 18 (hot water supply path) and the hot water inlet hole 35 is 55%. At this time, the hot and cold water mixture output via the hot and cold water outlet hole 36 and the hot and cold water outlet path is 45% water and 55% hot water (the flow rate is 100%).

[0101] Figure 11(f) shows a schematic state in which the shaft body 20 and cylinder body 30 have changed their rotational positions by further rotating the first operating part 41 from the state shown in Figure 11(e), so that the communication amount between the water side auxiliary pipe member 16 (water supply path) and the water inlet hole 34 is 22.5%, and the communication amount between the hot water side auxiliary pipe member 18 (hot water supply path) and the hot water inlet hole 35 is 27.5%. At this time, the hot and cold water mixture output through the hot and cold water outlet hole 36 and the hot and cold water outlet path is 45% water and 55% hot water, but the flow rate is 50%.

[0102] Figure 11(g) shows a schematic state in which the shaft body 20 and cylinder body 30 have changed their rotational positions by further rotating the first operating part 41 from the state shown in Figure 11(f), blocking communication between the water side auxiliary pipe member 16 (water supply path) and the water inlet hole 34, and also blocking communication between the hot water side auxiliary pipe member 18 (hot water supply path) and the hot water inlet hole 35. At this time, the hot and cold water mixture output via the hot and cold water outlet hole 36 and the hot and cold water outlet path is 0% water and 0% hot water (i.e., the flow rate is 0%).

[0103] As shown in Figures 11(a) to 11(g), in this modified example, by rotating the second operating unit 51, the ratio of the amount of communication between the water side auxiliary pipe member 16 (water supply channel) and the water inlet hole 34 and the amount of communication between the hot water side auxiliary pipe member 18 (hot water supply channel) and the hot water inlet hole 35 changes, thereby realizing temperature adjustment, and by rotating the first operating unit 41, the total amount of communication, which is the sum of the amount of communication between the water side auxiliary pipe member 16 (water supply channel) and the water inlet hole 34 and the amount of communication between the hot water side auxiliary pipe member 18 (hot water supply channel) and the hot water inlet hole 35, changes, thereby realizing flow rate adjustment.

[0104] [Basic effect] As described above, according to the faucet valve device 100 of this embodiment, a compact faucet valve design can be realized since both temperature adjustment and flow rate adjustment are realized according to the axial position and rotational position of the common cylinder body 30. In addition, since there is no obstacle to the motorization of the first operating part 41 and the second operating part 51, it is suitable for realizing the motorization of both temperature adjustment and flow rate adjustment.

[0105] Furthermore, according to the faucet valve device 100 of this embodiment, the ratio of the amount of communication between the water side auxiliary pipe member 16 (water supply passage) and the water inlet hole 34 and the amount of communication between the hot water side auxiliary pipe member 18 (hot water supply passage) and the hot water inlet hole 35 changes by rotating the first operating part 41, thereby realizing temperature adjustment. Then, the total amount of communication, which is the sum of the amount of communication between the water side auxiliary pipe member 16 (water supply passage) and the water inlet hole 34 and the amount of communication between the hot water side auxiliary pipe member 18 (hot water supply passage) and the hot water inlet hole 35, changes by rotating the second operating part 51, thereby realizing flow rate adjustment.

[0106] However, it is also possible to switch the functions of the first operating unit 41 and the second operating unit 51 by changing the positions of the water inlet hole 34 and the hot water inlet hole 35 in the cylinder body 30. That is, the ratio of the communication amount between the water side auxiliary pipe member 16 (water supply passage) and the water inlet hole 34 and the communication amount between the hot water side auxiliary pipe member 18 (hot water supply passage) and the hot water inlet hole 35 is changed by rotating the second operating unit 51 to realize temperature adjustment, and the total communication amount of the communication amount between the water side auxiliary pipe member 16 (water supply passage) and the water inlet hole 34 and the communication amount between the hot water side auxiliary pipe member 18 (hot water supply passage) and the hot water inlet hole 35 is changed by rotating the first operating unit 41 to realize flow rate adjustment.

[0107] Furthermore, according to the faucet valve device 100 of this embodiment, there is provided a shaft body 20 whose rotational position is changed by rotating the first operating part 41 without changing the axial position, and whose axial position is changed by rotating the second operating part 51 without changing the rotational position, and the cylinder body 30 is fixed (connected) to the shaft body 20. As a result, the control for changing the position of the cylinder body 30 is realized with a relatively simple configuration by the control for changing the position of the shaft body 20.

[0108] Furthermore, according to the faucet valve device 100 of this embodiment, the first operating part 41 and the second operating part 51 can be rotated simultaneously, and when the first operating part 41 and the second operating part 51 are rotated simultaneously, the shaft body 20 and the cylinder body 30 change their rotational positions while changing their axial positions. As a result, by operating the first operating part 41 and the second operating part 51 simultaneously, it is possible to achieve more rapid temperature adjustment and flow rate adjustment.

[0109] Furthermore, according to the faucet valve device 100 of this embodiment, a sliding tube 43 is provided as a first connecting member that is fixed (connected) to the shaft body 20 and fixed in the rotational direction relative to the first operating part 41, and the sliding tube 43 is movable in the axial direction relative to the first operating part 41. This ensures that the rotational operation of the first operating part 41 can be transmitted as a rotational force of the shaft body 20, while the presence of the sliding tube 43 (first connecting member) does not impede the operation of the second operating part 51.

[0110] Furthermore, the faucet valve device 100 of this embodiment is provided with the rotating cylinder 52 as a direction changing member that converts the rotational operating force of the second operating part 51 into an axial moving force, and the screw body 53 and the retaining ring 58 as second connecting members that are axially fixed while allowing relative rotation with respect to the shaft body 20 and that receive the axial moving force converted by the rotating cylinder 52. This makes it possible to reliably transmit the rotational operation of the second operating part 51 as an axial moving force of the shaft body 20.

[0111] Moreover, according to the faucet valve device 100 of this embodiment, the protruding region 54p of the retaining ring 54 is provided as a restricting member capable of adjusting the rotational range of the second operating part 51 as desired. As a result, the adjustment of the range of motion of the axial position of the cylinder body 30 relative to the housing body 10 can be realized by adjusting the rotational range of the second operating part 51 by the protruding region 54p of the retaining ring 54, so that the desired flow rate adjustment or temperature adjustment can be realized even if there is individual variation in each part based on manufacturing tolerances, etc.

[0112] [Effect of being open to the atmosphere] Moreover, according to the faucet valve device 100 of this embodiment, the shaft body 20 penetrates the cylinder body 30 in the axial direction, and both ends of the shaft body 20 are in an area that does not communicate with the internal space of the housing body 10 and are open to the atmosphere. This significantly reduces the effect of water pressure in the internal space of the housing body 10 on the shaft body 20. This reduces the torque (force) required to rotate or move the shaft body 20 in the axial direction, which is very convenient for achieving motorization.

[0113] In particular, according to the faucet valve device 100 of this embodiment, the left end of the shaft body 20 is blocked from communicating with the internal space of the housing body 10 by the resin sliding bearing (bush) 46b and the X-ring 47b, and the right end of the shaft body 20 is blocked from communicating with the internal space of the housing body 10 by the resin sliding bearing (bush) 56b and the X-ring 57b. This extremely effectively suppresses the effect of water pressure in the internal space of the housing body 10 on the shaft body 20. In addition, the diameters of the portions at the left and right ends of the shaft body 20 that are blocked from communicating with the internal space of the housing body 10 are equal, and are configured to cancel out the acting water pressure.

[0114] Furthermore, according to the faucet valve device 100 of this embodiment, both ends of the shaft body 20 are maintained in an atmosphere-open state even if the axial position of the shaft body 20 is changed by rotating the second operating part 51. As a result, even if the axial position of the shaft body 20 is changed, the torque required for each of the first operating part 41 and the second operating part 51 is small, which is very convenient for realizing motorization.

[0115] Furthermore, according to the faucet valve device 100 of this embodiment, a left lid member 47 and a right lid member 57 are provided to partition the internal space of the housing body 10. This makes it easy to assemble or disassemble (for example, for maintenance) the internal parts of the housing body 10 by removing the left lid member 47 and / or the right lid member 57.

[0116] Furthermore, according to the faucet valve device 100 of this embodiment, the left cover member 47 and the right cover member 57 are each located inward from the axial end of the housing body 10. This reduces the length of the shaft body 20, which is convenient for making the faucet valve device 100 compact.

[0117] Furthermore, according to the faucet valve device 100 of this embodiment, there is no rubber elastic member (so-called packing) between the housing body 10 and the cylinder body 30, and the housing body 10 and the cylinder body 30 are in direct contact with each other to provide a certain degree of sealing. This reduces the possibility that the operation of the cylinder body 30 inside the housing body 10 will be undesirably hindered. This also contributes to the fact that the torque (force) required to change the axial and rotational positions of the cylinder body 30 can be small.

[0118] [Effects of the water side auxiliary pipe parts and hot water side auxiliary pipe parts] Furthermore, according to the faucet valve device 100 of this embodiment, the water side auxiliary pipe member 16 can abut against the peripheral wall 33 of the cylinder body 30 and can communicate with the water inlet hole 34 depending on the water pressure difference between its one side and the other side, and similarly, the hot water side auxiliary pipe member 18 can abut against the peripheral wall 33 of the cylinder body 30 and can communicate with the hot water inlet hole 35 depending on the water pressure difference between its one side and the other side, so that the supply of water and hot water to the inside of the cylinder body 30 can be reliably assisted and there is no need to interpose a rubber elastic member between the housing body 10 and the cylinder body 30. This also contributes to the fact that the torque (force) required to change the axial position and rotational position of the cylinder body 30 can be small.

[0119] Furthermore, according to the faucet valve device 100 of this embodiment, the water side auxiliary pipe member 16 has a water side movement restricting portion that restricts the stroke of its sliding movement relative to the water supply passage, and the hot water side auxiliary pipe member 18 has a hot water side movement restricting portion that restricts the stroke of its sliding movement relative to the hot water supply passage. This makes it possible to restrict the movement stroke of the water side auxiliary pipe member 16 and the hot water side auxiliary pipe member 18 to a desired range, and prevents them from protruding toward the cylinder body 30 more than necessary.

[0120] In particular, according to the faucet valve device 100 of this embodiment, the water side movement restricting portion is provided as the flange portion 16f having a flange shape, and the hot water side movement restricting portion is also provided as the flange portion 18f having a flange shape. This allows the water side movement restricting portion and the hot water side movement restricting portion to be provided relatively simply.

[0121] Furthermore, according to the faucet valve device 100 of this embodiment, the hardness of the upper surface 16r of the water side auxiliary pipe member 16 and the upper surface 18r of the hot water side auxiliary pipe member 18 are smaller than the hardness of the peripheral wall 33 of the cylinder body 30. This prevents the cylinder body 30 from being undesirably worn. On the other hand, it is rather preferable that the upper surface 16r of the water side auxiliary pipe member 16 and the upper surface 18r of the hot water side auxiliary pipe member 18 wear in accordance with the peripheral wall 33 of the cylinder body 30.

[0122] In particular, according to the faucet valve device 100 of this embodiment, the peripheral wall 33 of the cylinder body 30 is a cylindrical surface having a predetermined radius of curvature, the upper surface 16r of the water side auxiliary pipe member 16 is part of a cylindrical surface having a predetermined radius of curvature, and the upper surface 18r of the hot water side auxiliary pipe member 18 is part of a cylindrical surface having a predetermined radius of curvature, and the radius of curvature of the upper surface 16r of the water side auxiliary pipe member 16 and the radius of curvature of the upper surface 18r of the hot water side auxiliary pipe member 18 are larger than the radius of curvature of the peripheral wall 33 of the cylinder body 30. This avoids a state in which only both ends in the arc-shaped direction of the upper surface 16r of the water side auxiliary pipe member 16 and the upper surface of the hot water side auxiliary pipe member 18 abut against the cylinder body 30 (ensuring that the central part in the arc-shaped direction abuts against the cylinder body 30), resulting in a good degree of adhesion between the upper surface 16r of the water side auxiliary pipe member 16 and the cylinder body 30, and similarly, a good degree of adhesion between the upper surface 18r of the hot water side auxiliary pipe member 18 and the cylinder body 30.

[0123] In addition, the faucet valve device 100 of this embodiment is provided with a hot and cold water stopper that stops the flow of hot and cold water. This ensures a reliable water stopper function even when the water is not completely stopped by simply adjusting the flow rate to the minimum using the flow rate adjustment function (when the sealing function in the cutoff control state is insufficient).

[0124] In particular, according to the faucet valve device 100 of this embodiment, the hot and cold water stop section is composed of a water stop section 11s provided upstream of the water supply passage and a hot and cold water stop section 13s provided upstream of the hot water supply passage, thereby preventing hot or cold water from flowing back to the upstream side of the other.
