[0002] The applicant of the present invention has realized the motorization of a flow control valve (Patent Document 1). In this flow control valve, the rotation of a stepping motor is converted into the linear movement of a guide valve body through a tappet.

[0003] Patent Literature

[0004] Patent Document 1: Japanese Patent Application Publication No. 2017-201200 Summary of the invention

[0005] Yet, for the electric faucet valve device that is applicable to realize both temperature regulation and flow rate regulation, there is no suitable scheme proposed yet.In addition, for the electric faucet valve device that is applicable to realize temperature regulation, there is no suitable scheme proposed yet.

[0006] Although the flow control valve of Patent Document 1 is suitable for electric flow control, two flow control valves need to be controlled independently for temperature control. Therefore, there is a problem that control becomes complicated when the temperature is changed without changing the flow rate, or the flow rate is changed without changing the temperature.

[0007] The present invention is an invention under the above background. The technical problem to be solved by the present invention is to provide an electric faucet valve device suitable for realizing both temperature adjustment and flow adjustment. Alternatively, the technical problem to be solved by the present invention is to provide an electric faucet valve device suitable for realizing temperature adjustment.

[0008] A first aspect of the present invention is a faucet valve device, comprising:

[0009] The cylindrical body is formed into a hollow cylindrical shape;

[0010] The cold water inlet hole, the hot water inlet hole and the cold and hot water outlet holes are respectively arranged in the peripheral wall of the cylindrical body;

[0011] A housing, which accommodates the cylindrical body so as to be axially movable and rotatable;

[0012] The cold water supply path, the hot water supply path and the cold and hot water outflow paths are respectively arranged to communicate with the internal space of the shell;

[0013] A first operating portion is rotatably disposed on one axial side of the cylindrical body;

[0014] and a second operating portion rotatably disposed on the other axial side of the cylindrical body,

[0015] It is characterized in that

[0016] The cylindrical body changes its rotational position by the rotational operation of the first operating part without changing its axial position, and changes its axial position by the rotational operation of the second operating part without changing its rotational position.

[0017] According to the axial position and rotational position of the cylinder, temperature adjustment and flow adjustment are both achieved by changing the connectivity between the cold water supply path and the cold water inlet hole, the connectivity between the hot water supply path and the hot water inlet hole, and / or the connectivity between the cold and hot water outlet hole and the cold and hot water outlet path.

[0018] According to the first aspect of the present invention, since both temperature adjustment and flow rate adjustment can be realized according to the common axial position and rotational position of the cylindrical body, a compact faucet valve design can be realized. In addition, since there is no obstacle to the motorization of the first operating part and the motorization of the second operating part, it is suitable for realizing the motorization of both temperature adjustment and flow rate adjustment.

[0019] In the first aspect of the present invention, for example, temperature adjustment is achieved by rotating the first operating part to change the ratio of the amount of communication between the cold water supply path and the cold water inlet hole to the amount of communication between the hot water supply path and the hot water inlet hole, and flow adjustment is achieved by rotating the second operating part to change the total amount of communication between the cold water supply path and the cold water inlet hole and the amount of communication between the hot water supply path and the hot water inlet hole.

[0020] Alternatively, conversely, flow adjustment can be achieved by rotating the first operating part to change the total communication volume of the cold water supply path and the cold water inlet hole and the hot water supply path and the hot water inlet hole, and temperature adjustment can be achieved by rotating the second operating part to change the ratio of the communication volume of the cold water supply path and the cold water inlet hole and the hot water supply path and the hot water inlet hole.

[0021] Furthermore, it is preferred that the first operating portion and the second operating portion can be rotationally operated simultaneously, and when the first operating portion and the second operating portion are rotationally operated simultaneously, the cylindrical body changes its rotational position while changing its axial position.

[0022] Thus, by operating the first operating unit and the second operating unit at the same time, more rapid temperature adjustment and flow rate adjustment can be achieved.

[0023] Furthermore, it is preferred that a shaft body is further provided, wherein the rotational position of the shaft body is changed by the rotational operation of the first operating portion without changing the axial position, and the axial position is changed by the rotational operation of the second operating portion without changing the rotational position, and the cylindrical body is connected to the shaft body.

[0024] Thus, control for changing the position of the cylindrical body can be achieved with a relatively simple configuration for controlling the position of the shaft body.

[0025] Furthermore, it is preferable to further include a first connecting member which is connected to or integrated with the shaft body and is rotationally fixed relative to the first operating portion, and is provided to be movable in the axial direction relative to the first operating portion.

[0026] Thus, the rotational operation of the first operating portion can be reliably transmitted as the rotational force of the shaft body, and on the other hand, the presence of the first connecting member does not hinder the operation of the second operating portion.

[0027] In addition, it is preferred to further include: a direction conversion component that converts the rotational operating force of the second operating portion into an axial movement force; and a second connecting component that, while being connected to the shaft body, receives the axial movement force converted by the direction conversion component, and the shaft body is configured to be rotatable relative to the second connecting component.

[0028] Thus, the rotational operation of the second operating portion can be reliably transmitted as the axial displacement force of the shaft body, and the presence of the second connecting member does not hinder the operation of the first operating portion.

[0029] Furthermore, it is preferable to further include a limiting member capable of adjusting the rotationally movable region of the second operating portion to a desired range.

[0030] Therefore, since the movable area of ​​the axial position of the cylinder relative to the shell can be adjusted by adjusting the rotational movable area of ​​the second operating part through the limiting component, the desired flow adjustment or temperature adjustment can be achieved even when there are individual differences in each part due to manufacturing tolerances, etc.

[0031] A second aspect of the present invention is a faucet valve device, comprising:

[0032] The cylindrical body is formed into a hollow cylindrical shape;

[0033] The cold water inlet hole, the hot water inlet hole and the cold and hot water outlet holes are respectively arranged in the peripheral wall of the cylindrical body;

[0034] A housing, which accommodates the cylindrical body so as to be axially movable and rotatable;

[0035] The cold water supply path, the hot water supply path and the cold and hot water outflow paths are respectively arranged to communicate with the internal space of the shell;

[0036] A first operating portion is rotatably disposed on one axial side of the cylindrical body;

[0037] and a second operating portion rotatably disposed on the other axial side of the cylindrical body,

[0038] A shaft body, connected to or integrated with the cylindrical body;

[0039] a first connecting member connected to or integrated with the shaft body and fixed in a rotational direction relative to the first operating portion;

[0040] a direction conversion component for converting the rotational operation force of the second operating part into an axial movement force;

[0041] and a second connecting member, which receives the axial movement force converted by the direction conversion member while being connected to or integrated with the shaft body.

[0042] It is characterized in that

[0043] The first connecting member is movable in the axial direction relative to the first operating portion.

[0044] The cylindrical body and the shaft body are configured to change the rotational position through the rotational operation of the first operating part and the rotation of the first connecting part, and on the other hand, are configured to change the axial position by utilizing the direction conversion part to convert the rotational operating force generated by the rotational operation of the second operating part into an axial movement force applied to the second connecting part.

[0045] According to the axial position and rotational position of the cylinder, temperature adjustment and flow adjustment are both achieved by changing the connectivity between the cold water supply path and the cold water inlet hole, the connectivity between the hot water supply path and the hot water inlet hole, and / or the connectivity between the cold and hot water outlet hole and the cold and hot water outlet path.

[0046] According to the second aspect of the present invention, since both temperature adjustment and flow rate adjustment can be achieved by using the common axial position and rotational position of the cylindrical body, a compact faucet valve design can be achieved.

[0047] Furthermore, according to the second aspect of the present invention, since there is no obstacle to the motorization of the first operating unit and the motorization of the second operating unit, it is suitable for realizing the motorization of both the temperature adjustment and the flow rate adjustment.

[0048] Furthermore, the faucet valve device of the second aspect of the present invention includes a shaft body connected to or integrated with the cylindrical body. Thus, control for changing the position of the cylindrical body can be achieved with a relatively simple structure for controlling the position of the shaft body.

[0049] In addition, the faucet valve device of the second aspect of the present invention includes a first connecting member, which is connected to or integrated with the shaft body and is fixed in the rotational direction relative to the first operating part, and the first connecting member is movable in the axial direction relative to the first operating part. Thus, the rotational operation of the first operating part can be effectively transmitted as the rotational force of the shaft body, and on the other hand, the existence of the first connecting member does not hinder the operation of the second operating part.

[0050] In addition, the faucet valve device of the second aspect of the present invention comprises: a direction conversion member that converts the rotational operation force of the second operating part into an axial movement force; and a second connecting member that receives the axial movement force converted by the direction conversion member while being connected or integrated with the shaft body. Thus, the rotational operation of the second operating part can be reliably transmitted as the axial movement force of the shaft body.

[0051] Preferably, the first connecting member is configured to move in the axial direction so as to change its relative position in the axial direction with respect to the first operating portion when the rotational operating force of the second operating portion is converted into an axial movement force applied to the cylindrical body and the shaft body by the direction changing member.

[0052] Furthermore, it is preferable that the shaft body is configured to be rotatable together with the first link member relative to the second link member when the first link member is rotated by the rotational operation of the first operating portion.

[0053] Thus, the rotational operation of the second operating portion can be reliably transmitted as the axial displacement force of the shaft body, and the presence of the second connecting member does not hinder the operation of the first operating portion.

[0054] In the second aspect of the present invention, for example, temperature adjustment is achieved by rotating the first operating part to change the ratio of the amount of communication between the cold water supply path and the cold water inlet hole to the amount of communication between the hot water supply path and the hot water inlet hole, and flow adjustment is achieved by rotating the second operating part to change the total amount of communication between the cold water supply path and the cold water inlet hole and the amount of communication between the hot water supply path and the hot water inlet hole.

[0055] Alternatively, conversely, flow adjustment can be achieved by rotating the first operating part to change the total amount of communication between the cold water supply path and the cold water inlet hole and the amount of communication between the hot water supply path and the hot water inlet hole, and temperature adjustment can be achieved by rotating the second operating part to change the ratio of the amount of communication between the cold water supply path and the cold water inlet hole and the amount of communication between the hot water supply path and the hot water inlet hole.

[0056] Furthermore, it is preferable to further include a limiting member capable of adjusting the rotationally movable region of the second operating portion to a desired range.

[0057] Therefore, since the movable area of ​​the axial position of the shaft body and the cylindrical body relative to the shell can be adjusted by adjusting the rotational movable area of ​​the second operating part through the limiting component, the desired flow adjustment or temperature adjustment can be achieved even when there are individual differences in each part due to manufacturing tolerances, etc.

[0058] A third aspect of the present invention is a faucet valve device, comprising:

[0059] The cylindrical body is formed into a hollow cylindrical shape;

[0060] The cold water inlet hole, the hot water inlet hole and the cold and hot water outlet holes are respectively arranged in the peripheral wall of the cylindrical body;

[0061] A housing, which accommodates the cylindrical body so as to be axially movable and rotatable;

[0062] The cold water supply path, the hot water supply path and the cold and hot water outflow paths are respectively arranged to communicate with the internal space of the shell;

[0063] A first operating portion is rotatably disposed on one axial side of the cylindrical body;

[0064] and a second operating portion rotatably disposed on the other axial side of the cylindrical body,

[0065] A shaft body, connected to or integrated with the cylindrical body;

[0066] It is characterized in that

[0067] Both ends of the shaft body are located in an area not connected to the internal space of the housing and are open to the atmosphere.

[0068] The cylindrical body and the shaft body change their rotational positions by the rotational operation of the first operating portion, and change their axial positions by the rotational operation of the second operating portion.

[0069] According to the axial position and rotational position of the cylinder, temperature adjustment and flow adjustment are both achieved by changing the connectivity between the cold water supply path and the cold water inlet hole, the connectivity between the hot water supply path and the hot water inlet hole, and / or the connectivity between the cold and hot water outlet hole and the cold and hot water outlet path.

[0070] According to the third aspect of the present invention, since both temperature adjustment and flow rate adjustment can be realized according to the axial position and rotational position of the common cylindrical body, a compact faucet valve design can be realized. In addition, according to the present invention, since there is no obstacle to the motorization of the first operating part and the motorization of the second operating part, it is suitable for realizing the motorization of both temperature adjustment and flow rate adjustment.

[0071] Furthermore, a faucet valve device according to a third aspect of the present invention includes a shaft body that penetrates the cylindrical body in the axial direction and is connected to or integrated with the cylindrical body.

[0072] Thus, it is possible to realize control of changing the position of the cylindrical body with a relatively simple configuration of controlling the position of the shaft body.

[0073] Furthermore, in a third aspect of the present invention, both ends of the shaft body are located in a region that is not communicated with the internal space of the housing and are open to the atmosphere.

[0074] Thus, the influence of the water pressure in the inner space of the housing on the shaft body can be significantly suppressed. Therefore, the torque (force) required to rotate or axially move the shaft body can be small, that is, it is very easy to realize electrification.

[0075] For example, the regions where the two ends of the shaft exist are blocked by a sealing member so as not to communicate with the internal space of the housing.

[0076] Furthermore, it is preferable that even if the axial position of the shaft body is changed by the rotational operation of the second operating portion, both ends of the shaft body are maintained in a state of being open to the atmosphere.

[0077] Thus, even if the axial position of the shaft body is changed by the rotation operation of the second operating part, the influence of the water pressure in the internal space of the housing on the shaft body can be maintained in a state where the influence is significantly suppressed. Therefore, the torque (force) required to rotate or axially move the shaft body can be small, that is, it is very easy to realize electrification.

[0078] In order to partition the internal space, the housing preferably includes a cover member on one axial side and a cover member on the other axial side.

[0079] Thus, by removing the cover member, the parts inside the housing can be easily assembled or disassembled (for example, for maintenance).

[0080] In this case, it is also preferable that each of the cover members of the housing is located further inward than an axial end portion of the housing.

[0081] This can reduce the length of the shaft, making it easier to make the faucet valve device more compact.

[0082] Furthermore, it is preferred that the housing and the cylindrical body are in direct contact with each other to have a certain degree of sealing.

[0083] Thus, compared with a case where an elastic body such as a seal ring is provided between the housing and the cylindrical body, a large friction force is not generated, and thus the movement of the cylindrical body inside the housing is less likely to be undesirably hindered.

[0084] Furthermore, it is preferable to further include a limiting member capable of adjusting the rotationally movable region of the second operating portion to a desired range.

[0085] Therefore, since the movable area of ​​the axial position of the shaft body and the cylindrical body relative to the shell can be adjusted by adjusting the rotational movable area of ​​the second operating part through the limiting component, the desired flow adjustment or temperature adjustment can be achieved even when there are individual differences in each part due to manufacturing tolerances, etc.

[0086] A fourth aspect of the present invention is a faucet valve device, comprising:

[0087] The cylindrical body is formed into a hollow cylindrical shape;

[0088] The cold water inlet hole, the hot water inlet hole and the cold and hot water outlet holes are respectively arranged in the peripheral wall of the cylindrical body;

[0089] A shell, accommodating the cylindrical body so as to be rotatable;

[0090] The cold water supply path, the hot water supply path and the cold and hot water outflow paths are respectively arranged to communicate with the internal space of the shell;

[0091] An operating portion is rotatably disposed on one axial side of the cylindrical body;

[0092] and a shaft body, which penetrates the cylindrical body in the axial direction and is connected to or integrated with the cylindrical body,

[0093] It is characterized in that

[0094] Both ends of the shaft body are located in an area not connected to the internal space of the housing and are open to the atmosphere.

[0095] The cylindrical body and the shaft body change their rotational positions by the rotation operation of the operating part.

[0096] Temperature adjustment is achieved by changing the amount of connectivity between the cold water supply path and the cold water inlet hole, the amount of connectivity between the hot water supply path and the hot water inlet hole, and / or the amount of connectivity between the cold and hot water outlet hole and the cold and hot water outlet path according to the rotational position of the cylinder.

[0097] According to the fourth aspect of the present invention, since the temperature can be adjusted according to the rotational position of the cylindrical body, a compact faucet valve design can be achieved.

[0098] Furthermore, according to the fourth aspect of the present invention, since there is no obstacle to the motorization of the operation portion, it is suitable for realizing the motorization of temperature adjustment.

[0099] Furthermore, a faucet valve device according to a fourth aspect of the present invention includes a shaft body that penetrates the cylindrical body in the axial direction and is connected to or integrated with the cylindrical body.

[0100] Thus, control for changing the position of the cylindrical body can be achieved with a relatively simple configuration for controlling the position of the shaft body.

[0101] Furthermore, in a fourth aspect of the present invention, both ends of the shaft body are located in a region that is not communicated with the internal space of the housing and are open to the atmosphere.

[0102] As a result, the influence of the water pressure in the internal space of the housing on the shaft body can be significantly suppressed.

[0103] Therefore, the torque (force) required to rotate the shaft can be small, that is, it is very easy to realize electrification.

[0104] For example, the regions where the two ends of the shaft exist are blocked by a sealing member so as not to communicate with the internal space of the housing.

[0105] Furthermore, it is preferable to further include a connecting member which is connected to or integrated with one end portion of the shaft body and is rotationally fixed relative to the operating portion, and is provided to be movable in the axial direction relative to the operating portion.

[0106] Thus, the rotational operation of the operating portion can be reliably transmitted as the rotational force of the shaft body, and at the same time, the force that can act in the axial direction of the shaft body does not hinder the operation of the operating portion.

[0107] Furthermore, it is preferable to further include a holding member that restricts the axial movement of the other end portion of the shaft body but does not restrict the rotation of the other end portion of the shaft body.

[0108] According to such a holding member, it is possible to restrict the axial movement of the other end portion of the shaft body and suppress the situation in which the rotation of the shaft body and thus the operation of the operating portion is hindered.

[0109] In order to partition the internal space, the housing preferably includes a cover member on one axial side and a cover member on the other axial side.

[0110] Thus, by removing the cover member, the parts inside the housing can be easily assembled or disassembled (for example, for maintenance).

[0111] In this case, it is also preferable that each of the cover members of the housing is located further inward than an axial end portion of the housing.

[0112] This can reduce the length of the shaft, making it easier to make the faucet valve device more compact.

[0113] According to the first aspect of the present invention, since both temperature adjustment and flow rate adjustment can be realized according to the common axial position and rotational position of the cylindrical body, a compact faucet valve design can be realized. In addition, since there is no obstacle to the motorization of the first operating part and the motorization of the second operating part, it is suitable for realizing the motorization of both temperature adjustment and flow rate adjustment.

[0114] According to the second aspect of the present invention, since both temperature adjustment and flow rate adjustment can be realized by the common axial position and rotational position of the cylindrical body, a compact faucet valve design can be realized. In addition, since there is no obstacle to the motorization of the first operating part and the motorization of the second operating part, it is suitable for realizing the motorization of both temperature adjustment and flow rate adjustment.

[0115] According to the third aspect of the present invention, since both temperature adjustment and flow rate adjustment can be realized by the common axial position and rotational position of the cylindrical body, a compact faucet valve design can be realized. In addition, since there is no obstacle to the motorization of the first operating part and the motorization of the second operating part, it is suitable for realizing the motorization of both temperature adjustment and flow rate adjustment.

[0116] According to the fourth aspect of the present invention, since the temperature can be adjusted according to the rotation position of the cylindrical body, a compact faucet valve design can be realized. In addition, according to the fourth aspect of the present invention, since it does not hinder the electrification of the operating part, it is suitable for realizing the electrification of temperature adjustment. In particular, according to the fourth aspect of the present invention, since both ends of the shaft body are in an area that is not connected to the internal space of the shell and are open to the atmosphere, the influence of the water pressure in the internal space of the shell on the shaft body can be significantly suppressed. As a result, the torque (force) required to rotate the shaft body can be small, that is, it is very easy to realize electrification. BRIEF DESCRIPTION OF THE DRAWINGS

[0156] Next, a faucet valve device according to a first embodiment of the present invention will be described with reference to the drawings. The faucet valve device 100 according to the first embodiment is an electric faucet valve device suitable for realizing both temperature adjustment and flow rate adjustment.

[0157] Figure 1 1 is a schematic perspective view of a faucet valve device 100 according to a first embodiment of the present invention. Figure 2 1 is a schematic front view of a faucet valve device 100 according to the first embodiment. Figure 3 1 is a schematic longitudinal sectional perspective view of the faucet valve device 100 according to the first embodiment. Figure 4 1 is a schematic longitudinal sectional view of the faucet valve device 100 according to the first embodiment. Figure 5 yes Figure 4 An enlarged view of the cylindrical part of Figure 6 This is a schematic perspective view showing the cylindrical body 30 and the shaft body 20 of the first embodiment extracted.

[0158] like Figures 1 to 6 As shown, the faucet valve device 100 of the first embodiment includes: a cylindrical body 30 configured in a hollow cylindrical shape; and a housing 10 that accommodates the cylindrical body 30 so as to be axially movable and rotatable.

[0159] (Cylinder 30)

[0160] The cylindrical body 30 has an outer diameter of 15 mm, a wall thickness of 0.5 mm, and an axial length of 50 mm, and is formed of stainless steel. When the cylindrical body 30 is formed of a resin material, it is preferable to make the wall thickness thicker.

[0161] Especially refer to Figure 5 A right end wall 31 made of resin is fitted on the right end of the cylindrical body 30 , and a left end wall 32 made of resin is fitted on the left end of the cylindrical body 30 .

[0162] A substantially rectangular cold water inlet hole 34 is provided in the right region of the peripheral wall 33 of the cylindrical body 30. The cold water inlet hole 34 opens at, for example, a circumferential angle (angle measured around the axis) of 0° (as a reference for the following description of the angular position) to 90°, and is formed in a region at a certain distance from the right end of the cylindrical body 30 in the axial direction.

[0163] A substantially rectangular hot water inlet hole 35 is provided in the left region of the peripheral wall 33 of the cylindrical body 30. The hot water inlet hole 35 opens at, for example, a circumferential angle (angle measured around the axis) of 90° to 180° (i.e., opens at an angular position different from that of the cold water inlet hole 34), and is formed in a region at a certain distance from the left end of the cylindrical body 30 in the axial direction.

[0164] A hot and cold water outflow hole 36 is provided in a substantially axially central region of the peripheral wall 33 of the cylindrical body 30 .

[0165] In addition, the cylindrical body 30 of this embodiment has a central tube portion 37 extending from the right end wall 31 to the left end wall 32. A partition wall 38 (also see FIG. 38 ) extending radially outward from the central tube portion 37 is provided at an axial position corresponding to the hot and cold water outflow hole 36 of the cylindrical body 30. Figure 6 ).

[0166] (Axis 20)

[0167] Then, the shaft body 20 passes through the center tube portion 37 and is fixed by the right end wall 31 and the left end wall 32. Thus, the shaft body 20 and the cylindrical body 30 rotate and move axially together. The shaft body 20 is, for example, φ3 and is made of stainless steel.

[0168] (Housing 10)

[0169] The inner space of the housing 10 accommodating the cylindrical body 30 is, for example, a cylindrical space, and a gap is provided between the housing 10 and the peripheral wall 33 of the cylindrical body 30. The housing 10 is also formed of stainless steel. On the other hand, the housing 10 has a substantially square columnar appearance and is formed of PPS resin.

[0170] Especially refer to Figure 4 and Figure 5 The left end of the internal space of the housing 10 is divided by the left cover member 47. The left cover member 47 is a substantially disc-shaped member and is fitted into the inner peripheral step surface of the housing 10 via an O-ring 47a. In addition, the left cover member 47 is provided with a through hole for passing the shaft body 20 in the central portion. The through hole is sealed by an X-shaped sealing ring 47b while allowing the shaft body 20 to rotate and move in the axial direction.

[0171] Similarly, the right end of the internal space of the housing 10 is divided by the right side cover member 57. The right side cover member 57 is a substantially disc-shaped member, and is fitted into the inner peripheral step surface of the housing 10 via an O-ring 57a. In addition, the right side cover member 57 is provided with a through hole for passing the shaft body 20 in the center. The through hole is sealed by an X-shaped sealing ring 57b while allowing the shaft body 20 to rotate and move in the axial direction.

[0172] Furthermore, a cold water supply path, a hot water supply path, and cold and hot water outflow paths are provided on the housing 10 so as to communicate with the internal space thereof.

[0173] Specifically, the hot and cold water outflow path of this embodiment is provided by the hot and cold water outflow outlet 15 integrated with the housing 10. The hot and cold water outflow outlet 15 opens toward the upper side of the housing 10 and is connected to the hot and cold water supply pipe 63 via an elbow connection pipe 62, for example.

[0174] In addition, the cold and hot water outflow outlet 15 is set at a size and position so that the cold and hot water outflow holes 36 of the cylindrical body 30 can all be connected when the cylindrical body 30 is in any position and posture within the movable area.

[0175] On the other hand, the cold water supply route of the present embodiment is provided by a cold water supply pipe 11 that can be removed from the housing 10, and a cold water side communication hole 12 that communicates the cold water supply pipe 11 with the internal space of the housing 10. The cold water supply pipe 11 is fitted into a connection port 11r provided on the lower surface of the housing 10 via an O-ring. The cold water supply pipe 11 side of the cold water side communication hole 12 is a circular cross-section hole, and the internal space side of the housing 10 is a rectangular cross-section hole that converges within the circular cross-section.

[0176] Similarly, the hot water supply route of this embodiment is provided by a hot water supply pipe 13 that can be removed from the housing 10, and a hot water side communication hole 14 that communicates with the internal space of the housing 10 in the hot water supply pipe 13. Like the cold water supply pipe 11, the hot water supply pipe 13 is also fitted into a connection port 13r provided on the lower surface of the housing 10 via an O-ring. Like the cold water side communication hole 12, the hot water supply pipe 13 side of the hot water side communication hole 14 is also a circular cross-section hole, and the internal space side of the housing 10 is a rectangular cross-section hole that converges within the circular cross-section.

[0177] (Auxiliary pipe parts 16, 18)

[0178] Furthermore, the lower side (an example of one side) of the cold water side auxiliary pipe component 16 is accommodated inside the cold water side connecting hole 12. The cold water side auxiliary pipe component 16 can slide upward or downward inside the cold water side connecting hole 12 according to the water pressure difference between its lower side and upper side (an example of the other side). Specifically, a sealing ring 17 (cold water side sealing component) is inserted between the cold water side connecting hole 12 and the cold water side auxiliary pipe component 16, and the sealing ring 17 holds the cold water side auxiliary pipe component 16 so that it can slide upward or downward relative to the cold water side connecting hole 12. Furthermore, when the cold water side auxiliary pipe component 16 moves upward, the upper side (an example of the other side) of the cold water side auxiliary pipe component 16 can abut against the peripheral wall 33 of the cylindrical body 30, and can be connected to the cold water inlet hole 34.

[0179] Figure 7: is a schematic perspective view of the cold water side auxiliary pipe component 16 of this embodiment. Figure 7 As shown, the cold water side auxiliary pipe component 16 of the present embodiment has a flange portion 16f as a cold water side movement limiting portion, which can limit the sliding stroke relative to the inside of the cold water side connecting hole 12. The flange portion 16f is accommodated in the circular cross-sectional hole on the cold water supply pipe 11 side of the cold water side connecting hole 12, and has a size that does not enter the rectangular cross-sectional hole of the cold water side connecting hole 12, so that the movement of the cold water side auxiliary pipe component 16 is limited by the abutment of the flange portion 16f. In the present embodiment, the sliding stroke of the cold water side auxiliary pipe component 16 is 1 mm. In addition, the cold water side auxiliary pipe component 16 has a groove portion 16g for fitting the sealing ring 17.

[0180] like Figure 7 As shown, at the time of shipment (before use), the upper surface 16r of the cold water side auxiliary pipe component 16 is a part of a cylindrical surface with a curvature radius of 10 mm (preferably in the range of 5 mm to 15 mm). That is, the curvature radius is slightly larger than the curvature radius (8.5 mm) of the peripheral wall 33 of the cylindrical body 30. As a result, it is possible to avoid a state in which only the two ends of the arc-shaped direction of the upper surface 16r of the cold water side auxiliary pipe component 16 abut against the cylindrical body 30 (a state produced when the magnitude relationship of the curvature radius is opposite), that is, it is possible to ensure that the central part of the arc-shaped direction of the upper surface 16r of the cold water side auxiliary pipe component 16 abuts against the cylindrical body 30, so that the upper surface 16r of the cold water side auxiliary pipe component 16 and the cylindrical body 30 have good fit.

[0181] Furthermore, the hardness of the cold water side auxiliary pipe member 16 (at least the upper surface) is smaller than the hardness of the peripheral wall 33 of the cylindrical body 30. Thus, it is possible to suppress the occurrence of undesired wear of the peripheral wall 33 of the cylindrical body 30, and on the other hand, it is expected that the upper surface 16r of the cold water side auxiliary pipe member 16 will wear in a manner conforming to the peripheral wall 33 of the cylindrical body 30, which is appropriate for the close fit between the upper surface 16r of the cold water side auxiliary pipe member 16 and the cylindrical body 30. On the other hand, since the flange portion 16f, which is a cold water side movement restriction portion, restricts the amount of movement, it is possible to suppress excessive wear.

[0182] The magnitude of the hardness can be determined, for example, by Vickers hardness, which can be obtained by a test specified by ISO International Standard 6507 (JIS Japanese Industrial Standard Z 2244). The cold water side auxiliary pipe member 16 of this embodiment is made of polyacetal resin, and its hardness is significantly lower than that of the peripheral wall 33 of the stainless steel cylinder 30.

[0183] The size and position (in the axial direction of the housing 10) of the tube hole 16h of the cold water side auxiliary pipe member 16 are such that the tube hole 16h can be connected to the entire cold water inlet hole 34 when the communication amount between the cold water side auxiliary pipe member 16 and the cold water inlet hole 34 is controlled to be maximum (see the following description). Fig. 9 and Figures 10A-10G ).

[0184] Similarly, the lower side (an example of one side) of the hot water side auxiliary pipe component 18 is accommodated inside the hot water side connecting hole 14. The hot water side auxiliary pipe component 18 can slide upward or downward inside the hot water side connecting hole 14 according to the water pressure difference between its lower side and upper side (an example of the other side). Specifically, a sealing ring 19 (hot water side sealing component) is inserted between the hot water side connecting hole 14 and the hot water side auxiliary pipe component 18, and the sealing ring 19 holds the hot water side auxiliary pipe component 18 so that it can slide upward or downward relative to the hot water side connecting hole 14. Moreover, when the hot water side auxiliary pipe component 18 moves upward, the upper side (an example of the other side) of the hot water side auxiliary pipe component 18 can abut against the peripheral wall 33 of the cylindrical body 30, and can be connected to the hot water inlet hole 35.

[0185] Figure 7 This is also a schematic perspective view of the hot water side auxiliary pipe component 18 of this embodiment. Figure 7 As shown, the hot water side auxiliary pipe component 18 of the present embodiment also has a flange portion 18f as a hot water side movement limiting portion, which can limit the sliding stroke relative to the inside of the hot water side connecting 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 connecting hole 14, and has a size that does not enter the rectangular cross-sectional hole of the hot water side connecting hole 14, so that the movement of the hot water side auxiliary pipe component 18 is limited by the abutment of the flange portion 18f. In the present embodiment, the sliding stroke of the hot water side auxiliary pipe component 18 is 5 mm. In addition, the hot water side auxiliary pipe component 18 has a groove portion 18g for fitting the sealing ring 19.

[0186] like Figure 7As shown, at the time of shipment (before use), the upper surface 18r of the hot water side auxiliary pipe component 18 also becomes a part of the cylindrical surface with a curvature radius of 10 mm (preferably in the range of 5 mm to 15 mm). That is, the curvature radius is slightly larger than the curvature radius (8.5 mm) of the peripheral wall 33 of the cylindrical body 30. As a result, it is possible to avoid a state in which only the two end portions of the arc-shaped direction of the upper surface 18r of the hot water side auxiliary pipe component 18 abut against the cylindrical body 30 (a state produced when the magnitude relationship of the curvature radii is opposite), that is, it is possible to ensure that the central portion of the arc-shaped direction of the upper surface 18r of the hot water side auxiliary pipe component 18 abuts against the cylindrical body 30, so that the upper surface 18r of the hot water side auxiliary pipe component 18 and the cylindrical body 30 have good fit.

[0187] Furthermore, the hardness of the hot water side auxiliary pipe member 18 (at least the upper surface) is also lower than the hardness of the peripheral wall 33 of the cylindrical body 30. As a result, it is possible to suppress the occurrence of undesired wear of the peripheral wall 33 of the cylindrical body 30, and on the other hand, it is expected that the upper surface 18r of the hot water side auxiliary pipe member 18 will wear in a manner conforming to the peripheral wall 33 of the cylindrical body 30, which is appropriate for the close fit between the upper surface 18r of the hot water side auxiliary pipe member 18 and the cylindrical body 30. On the other hand, since the flange portion 18f, which is a hot water side movement restriction portion, restricts the amount of movement, it is possible to suppress excessive wear.

[0188] The hot water side auxiliary pipe member 18 of the present embodiment is also made of polyacetal resin, and its hardness is also significantly lower than the hardness of the peripheral wall 33 of the cylindrical body 30 made of stainless steel.

[0189] The size and position (in the axial direction of the housing 10) of the pipe hole 18h of the hot water side auxiliary pipe member 18 are such that the pipe hole 18h can communicate with the entire hot water inlet hole 35 when the communication amount between the hot water side auxiliary pipe member 18 and the hot water inlet hole 35 is controlled to be maximum (see the following description). Fig. 9 and Figures 10A-10G ).

[0190] (First operating mechanism 40)

[0191] like Figures 1 to 4 As shown, a first operating mechanism 40 is provided on the left side (one axial side) of the cylindrical body 30. The first operating mechanism 40 has a first operating portion 41 that is configured to be rotatable. In this embodiment, the first operating portion 41 is a stepping motor that receives a control command from a control main body (not shown) and can perform a rotational operation according to the control command.

[0192] In the present embodiment, the rotational positions of the shaft body 20 and the cylindrical body 30 can be changed by the rotation operation of the first operating portion 41 , and the axial positions thereof are not changed.

[0193] Specifically, especially Figure 4 As shown, the rotating shaft (output shaft) 41s of the first operating part 41 is fixed in both the axial and rotational directions at the bottom of the rotating cylinder 42. The rotating cylinder 42 is arranged with its bottom located on the left side and is held in the outer cylinder 45 so as to be rotatable around the axis.

[0194] The outer shell 45 also holds the main body of the first operating part 41 (near the rotating shaft 41s) via the retaining ring 44 on its left side. In addition, the outer shell 45 is connected (engaged) to the left end of the housing 10 and the left cover member 47 via the connecting ring 46 on its right side. A resin sliding bearing (bushing) 46b (see FIG. 1 ) for passing the shaft body 20 is provided at the center of the connecting ring 46. Figure 5 ).

[0195] The right side (opposite to the bottom) of the rotating cylinder 42 is open, and a sliding cylinder 43 that can slide in the axial direction is embedded therein, and the rotating cylinder 42 and the sliding cylinder 43 are fixed in the rotation direction. For example, the sliding cylinder 43 has four protrusions protruding in a cross shape in the axial section, and the rotating cylinder 42 has four recesses that accommodate the four protrusions in a manner that can slide in the axial direction. That is, the four protrusions are each accommodated in the four recesses, and when the rotating cylinder 42 rotates, the sliding cylinder 43 also rotates. When the sliding cylinder 43 rotates, the shaft body 20 and the cylindrical body 30 also rotate. On the other hand, the sliding cylinder 43 is housed in the rotating cylinder 42 and is not fixed in the axial direction relative to the rotating cylinder 42. That is, even if the shaft body 20 moves in the axial direction, the rotating cylinder 42 can be suppressed from moving in the axial direction, or it can idle relative to the rotating cylinder 42 without applying force in the axial direction. (Therefore, even if the operating force of the second operating portion 51 described later is relatively small, the shaft body 20 and the cylindrical body 30 can be fully moved in the axial direction).

[0196] The slide cylinder 43 is fixed to the left end of the shaft body 20. Thus, the slide cylinder 43 is fixed in the rotation direction relative to the rotation shaft 41s of the first operating part 41 as the first connecting member, and is movable in the axial direction relative to the rotation shaft 41s of the first operating part 41.

[0197] In this embodiment, the first operating portion 41 can provide a maximum rotation operation of 90°+α.

[0198] (Second operating mechanism 50)

[0199] On the other hand, a second operating mechanism 50 is provided on the right side (the other axial side) of the cylindrical body 30. The second operating mechanism 50 has a second operating portion 51 that is arranged to be rotatable. In the present embodiment, the second operating portion 51 is also a stepping motor that wirelessly receives a control command from a control main body (not shown) and can perform a rotational operation according to the control command.

[0200] In the present embodiment, the shaft body 20 and the cylindrical body 30 can change the axial position by the rotation operation of the second operating portion 51 , and the rotation position does not change.

[0201] Specifically, especially Figure 4 As shown, the rotating shaft (output shaft) 51s of the second operating part 51 is fixed to the bottom of the rotating cylinder 52 in both the axial direction and the rotation direction. The rotating cylinder 42 is arranged with its bottom on the right side and is held in the outer cylinder 55 so as to be rotatable around the axis.

[0202] The outer shell 55 also holds the main body of the second operating part 51 (the position near the rotating shaft 51s) via the retaining ring 54 on its right side. In addition, the outer shell 55 is connected (engaged) to the right end of the housing 10 and the right cover member 57 via the connecting ring 56 on its left side. A resin sliding bearing (bushing) 56b (see FIG. 1 ) for passing the shaft body 20 is also provided in the center of the connecting ring 56. Figure 5 ).

[0203] Inside the rotating cylinder 52, a space corresponding to two trapezoidal internal threads of a pitch of 16 is formed, and the left side (opposite to the bottom side) is open. In this space, a screw body 53 corresponding to two trapezoidal external threads of a pitch of 16 is screwed. The left end of the screw body 53 is located further to the left than the left end of the rotating cylinder 52, and has a protrusion 53p (for example, two places above and below) protruding into the axial grooves 55g and 56g (for example, two places above and below) provided on the inner surface of the outer shell cylinder 55 (and the inner surface of the cylindrical portion of the connecting ring 56 in this embodiment), and can slide in the axial direction in the axial grooves 55g and 56g. Therefore, when the output shaft 51s of the second operating part 51 rotates, the rotating cylinder 52 also rotates. On the other hand, the screw body 53 can move in the axial direction through the screwing of the internal space of the rotating cylinder 52 and the screw body 53 and the engagement of the axial grooves 55g and 56g with the protrusion 53p.

[0204] Moreover, the screw body 53 holds the right end portion of the shaft body 20 via a pair of retaining rings 58. Therefore, although the screw body 53 and the shaft body 20 can rotate with each other, they are fixed in the axial direction, so that the shaft body 20 can move axially through the axial movement of the screw body 53. That is, the shaft body 20 is accommodated in the rotating cylinder 52 in a rotatable state relative to the screw body 53, so that even if the shaft body 20 rotates, the screw body 53 can be suppressed from rotating in the same manner, or it can idle relative to the screw body 53 without applying force in the rotation direction. (Therefore, even if the operating force of the aforementioned first operating part 41 is relatively small, the shaft body 20 and the cylindrical body 30 can be fully rotated)

[0205] According to the above structure, the rotating cylinder 52 (the space corresponding to the two trapezoidal internal threads) can be used as a direction conversion component to convert the rotational operating force of the second operating part 51 into an axial movement force, and the screw body 53 and the retaining ring 58 serve as the second connecting component to receive the axial movement force converted by the rotating cylinder 52.

[0206] In this embodiment, the second operating portion 51 can provide a rotation operation of up to about 150°. Thus, the shaft body 20 (and the cylindrical body 30) has a movement stroke of about 6.0 mm in the axial direction.

[0207] (Restriction member of the second operating section)

[0208] The faucet valve device 100 of this embodiment further includes a limiting member that can adjust the rotational movable range of the second operating portion 51 to a desired range. Figure 8A-8C As shown, since the protruding area 54p arranged on the inner circumference of the retaining ring 54 acts as a limiting component to block a portion of the rotation track of the limiter 52s arranged on the outer circumference of the rotating cylinder 52, the rotational movable area of ​​the rotating cylinder 52 (i.e., the rotational movable area of ​​the second operating part) can be adjusted.

[0209] Fig. 8A This is a side view of the protruding area 54p provided on the inner peripheral surface of the retaining ring 54 as viewed from the inner side. Figure 8B and Figure 8C This is a stereoscopic view of the protruding area 54p observed from the inner side. FIG. 8A to FIG. 8C As shown, in the present embodiment, the protruding area 54p extends over approximately 210°, so that the rotationally movable area of ​​the rotating cylinder 52 (ie, the rotationally movable area of ​​the second operating portion) can be limited to approximately 150°.

[0210] Moreover, the fixed position of the outer shell 55 relative to the retaining ring 54 can be adjusted manually in the circumferential direction by using the long hole 54h. As a result, the rotational movable area of ​​the rotating cylinder 52 (i.e., the rotational movable area of ​​the second operating part 51) can be adjusted to match the desired axial movable area of ​​the shaft body 20 (and the cylindrical body 30). That is, the movable area of ​​the axial position of the shaft body 20 and the cylindrical body 30 relative to the housing 10 can be adjusted by adjusting the rotational movable area of ​​the second operating part 51 by adjusting the fixed position of the retaining ring 54 (limiting member). Therefore, even if there is unevenness of each individual due to manufacturing tolerances, etc. on each part, the desired flow adjustment or temperature adjustment described later can be achieved with high precision.

[0211] (Both ends of the shaft 20)

[0212] According to the above-described configuration, both ends of the shaft body 20 of the present embodiment are located in a region that is isolated from the internal space of the housing 10 and is open to the atmosphere (subject to atmospheric pressure instead of water pressure).

[0213] Specifically, the left end of the shaft body 20 is separated by a resin sliding bearing (bushing) 46b and an X-shaped sealing ring 47b, so that it will not be connected to the internal space of the housing 10. The right end of the shaft body 20 is separated by a resin sliding bearing (bushing) 56b and an X-shaped sealing ring 57b, so that it will not be connected to the internal space of the housing 10.

[0214] Thus, the influence of the water pressure in the internal space of the housing 10 on the shaft body 20 can be significantly suppressed. Therefore, the torque (force) required to rotate or axially move the shaft body 20 (and the cylindrical body 30) can be smaller, that is, the torque required on each of the first operating part 41 and the second operating part 51 can be smaller. It is better if the diameters of the cut-off parts in the shaft body 20 are the same.

[0215] In addition, even if the axial position of the shaft body 20 changes due to the rotation operation of the second operating part 51, both ends of the shaft body 20 remain open to the atmosphere. Therefore, even if the axial position of the shaft body 20 changes, the torque required on each of the first operating part 41 and the second operating part 51 can be small.

[0216] In addition, although the housing 10 has a left cover member 47 and a right cover member 57 to partition the internal space, by removing these cover members 47 and 57, the internal parts of the housing 10 can be easily assembled or disassembled (for example, for maintenance, etc.).

[0217] Furthermore, in the present embodiment, the cover members 47 and 57 of the housing 10 are respectively located inward of the axial end portions of the housing 10 , so that the length of the shaft body 20 can be suppressed.

[0218] (Water stop function)

[0219] In addition, the faucet valve device 100 of the present embodiment also has a hot and cold water stop portion for stopping the hot and cold water. In order to minimize the sliding resistance of the cylindrical body 30 and reduce the operating torque required for flow adjustment and temperature adjustment, even if there is no perfect sealing performance, the hot and cold water stop portion can be additionally provided to achieve reliable water stopping.

[0220] Specifically, the cold and hot water stop portion includes a cold water stop portion 11s provided on the upstream side of the cold water supply path, and a hot water stop portion 13s provided on the upstream side of the hot water supply path (see Figure 2 ). This prevents hot water or cold water from flowing back to the upstream side of the other side.

[0221] (Function of the faucet valve device 100)

[0222] Next, the operation of the faucet valve device 100 according to the present embodiment will be described.

[0223] According to the above configuration, the cylindrical body 30 of this embodiment can change the rotational position without changing the axial position by rotating the first operating part 41 , and can change the axial position without changing the rotational position by rotating the second operating part 51 .

[0224] Furthermore, both temperature adjustment and flow rate adjustment can be achieved by changing the amount of communication between the cold water side auxiliary pipe member 16 (cold water supply path) and the cold 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 according to the axial position and rotational position of the cylindrical body 30. In this embodiment, the cold and hot water outflow hole 36 and the cold and hot water outflow path are always maintained in a good communication state. Fig. 9 This is a schematic diagram showing a state in which the cold water side auxiliary pipe member 16 and the hot water side auxiliary pipe member 18 are in contact with the cylindrical body 30 according to the present embodiment.

[0225] In addition, in the present embodiment, by rotating the first operating part 41, the ratio of the communication volume between the cold water side auxiliary pipe member 16 (cold water supply path) and the cold water inflow hole 34 and the communication volume between the hot water side auxiliary pipe member 18 (hot water supply path) and the hot water inflow hole 35 is changed, thereby achieving temperature adjustment. Moreover, by rotating the second operating part 51, the total communication volume of the total communication volume of the cold water side auxiliary pipe member 16 (cold water supply path) and the cold water inflow hole 34 and the communication volume of the hot water side auxiliary pipe member 18 (hot water supply path) and the hot water inflow hole 35 is changed, thereby achieving flow adjustment.

[0226] FIG. 10A to FIG. 10G 2 is a schematic diagram for explaining the position control of the cylindrical body 30 in the present embodiment. In the present embodiment, the temperature is adjusted according to the rotational position of the cylindrical body 30 , and the flow rate is adjusted according to the axial position of the cylindrical body 30 .

[0227] Fig. 10A The positions of the cold water inlet 34 and the hot water inlet 35 on the peripheral wall 33 of the cylindrical body 30 are schematically shown.

[0228] Fig. 10B The schematic diagram shows a state in which the connection between the cold water side auxiliary pipe member 16 (cold water supply path) and the cold water inflow hole 34 is at its maximum, and the connection between the hot water side auxiliary pipe member 18 (hot water supply path) and the hot water inflow hole 35 is cut off. At this time, the cold and hot mixed water outputted through the cold and hot water outflow hole 36 and the cold and hot water outflow path is cold water: 100%, hot water: 0% (flow rate is 100%).

[0229] Fig. 10C Schematically, there are Fig. 10B From the state of the first operation part 41, the shaft body 20 and the cylindrical body 30 change the rotational position by the rotation operation of the first operation part 41, and then the communication amount between the cold water side auxiliary pipe component 16 (cold water supply path) and the cold water inflow hole 34 is 50%, and the communication amount between the hot water side auxiliary pipe component 18 (hot water supply path) and the hot water inflow hole 35 is also 50%. At this time, the cold and hot mixed water output through the cold and hot water outflow hole 36 and the cold and hot water outflow path is cold water: 50%, hot water: 50% (flow rate is 100%).

[0230] Fig. 10D Schematically, there are Fig. 10C , the shaft body 20 and the cylindrical body 30 change their rotational positions by further rotating the first operating part 41, and the connection between the cold water side auxiliary pipe component 16 (cold water supply path) and the cold water inlet hole 34 is cut off, and the connection between the hot water side auxiliary pipe component 18 (hot water supply path) and the hot water inlet hole 35 is maximized. At this time, the cold and hot mixed water outputted through the cold and hot water outflow hole 36 and the cold and hot water outflow path is cold water: 0%, hot water: 100% (flow rate is 100%).

[0231] Fig. 10E Schematically, there are Fig. 10C From the state, the shaft body 20 and the cylindrical body 30 change the rotational position by further rotating the first operating part 41, and then the state is such that the communication amount between the cold water side auxiliary pipe component 16 (cold water supply path) and the cold water inflow hole 34 is 45%, and the communication amount between the hot water side auxiliary pipe component 18 (hot water supply path) and the hot water inflow hole 35 is 55%. At this time, the cold and hot mixed water output through the cold and hot water outflow hole 36 and the cold and hot water outflow path is cold water: 45%, hot water: 55% (flow rate is 100%).

[0232] Fig.10F Schematically, there are Fig. 10E From the state, the shaft body 20 and the cylindrical body 30 change the axial position by further rotating the second operating part 51, and then the communication amount between the cold water side auxiliary pipe component 16 (cold water supply path) and the cold water inlet hole 34 is 22.5%, and the communication amount between the hot water side auxiliary pipe component 18 (hot water supply path) and the hot water inlet hole 35 is 27.5%. At this time, the cold and hot mixed water output through the cold and hot water outflow hole 36 and the cold and hot water outflow path is cold water: 45%, hot water: 55%, but the flow rate is 50%.

[0233] Figure 10G Schematically, there are Fig.10F, the shaft body 20 and the cylindrical body 30 change their axial positions by further rotating the second operating part 51, and the connection between the cold water side auxiliary pipe component 16 (cold water supply path) and the cold water inlet hole 34 is cut off, and the connection between the hot water side auxiliary pipe component 18 (hot water supply path) and the hot water inlet hole 35 is also cut off. At this time, the cold and hot mixed water output through the cold and hot water outflow hole 36 and the cold and hot water outflow path is cold water: 0%, hot water: 0% (that is, the flow rate is 0%).

[0234] like FIG. 10A to FIG. 10G As shown, in the present embodiment, by the rotation operation of the first operating part 41, the ratio of the communication volume between the cold water side auxiliary pipe component 16 (cold water supply path) and the cold water inlet hole 34 and the communication volume between the hot water side auxiliary pipe component 18 (hot water supply path) and the hot water inlet hole 35 is changed, thereby achieving temperature adjustment, and by the rotation operation of the second operating part 51, the total communication volume of the sum of the communication volume between the cold water side auxiliary pipe component 16 (cold water supply path) and the cold water inlet hole 34 and the communication volume between the hot water side auxiliary pipe component 18 (hot water supply path) and the hot water inlet hole 35 is changed, thereby achieving flow adjustment.

[0235] In addition, the first operating part 41 and the second operating part 51 can be rotated at the same time. When the first operating part 41 and the second operating part 51 are rotated at the same time, the shaft body 20 and the cylindrical body 30 change the rotational position while changing the axial position. Thus, by operating the first operating part 41 and the second operating part 51 at the same time, more rapid temperature adjustment and flow rate adjustment can be achieved.

[0236] (Variation Example)

[0237] In the above-mentioned embodiment, the functions of the first operating part 41 and the second operating part 51 can be exchanged by, for example, changing the positions of the cold water inflow hole 34 and the hot water inflow hole 35. That is, by rotating the first operating part 41, the total communication volume of the cold water side auxiliary pipe component 16 (cold water supply path) and the cold water inflow hole 34 and the communication volume of the hot water side auxiliary pipe component 18 (hot water supply path) and the hot water inflow hole 35 can be changed, thereby achieving flow adjustment, and by rotating the second operating part 51, the ratio of the cold water side auxiliary pipe component 16 (cold water supply path) and the cold water inflow hole 34 and the hot water side auxiliary pipe component 18 (hot water supply path) and the hot water inflow hole 35 can be changed, thereby achieving temperature adjustment.

[0238] In this modification, for example, the cold water inlet hole 34 opens at a circumferential angle (angle measured around the axis) of 0° to 90° and is formed in a region a certain distance from the right end of the cylindrical body 30 in the axial direction.

[0239] Moreover, for example, the hot water inlet hole 35 is opened at a circumferential angle (angle measured around the axis) of 0° to 90° (i.e., opened at the same angular position as the cold water inlet hole 34), and is formed in an area at a certain distance from the left end of the cylindrical body 30 in the axial direction.

[0240] Figures 11A-11G 2 is a schematic diagram for explaining the position control of the cylindrical body 30 in such a modification. In this modification, the temperature can be adjusted according to the axial position of the cylindrical body 30, and the flow rate can be adjusted according to the rotational position of the cylindrical body 30.

[0241] Fig.11A The positions of the cold water inlet 34 and the hot water inlet 35 on the peripheral wall 33 of the cylindrical body 30 are schematically shown.

[0242] Fig. 11B The schematic diagram shows a state in which the communication between the cold water side auxiliary pipe member 16 (cold water supply path) and the cold water inflow hole 34 is at a maximum, and the communication between the hot water side auxiliary pipe member 18 (hot water supply path) and the hot water inflow hole 35 is cut off. At this time, the cold and hot mixed water output through the cold and hot water outflow hole 36 and the cold and hot water outflow path is cold water: 100%, hot water: 0% (flow rate is 100%).

[0243] Fig. 11C Schematically, there are Fig. 11B From the state of the cold water supply hole 36, the shaft body 20 and the cylindrical body 30 change the axial position by the rotation operation of the second operating part 51, and then the communication amount between the cold water side auxiliary pipe component 16 (cold water supply path) and the cold water inflow hole 34 is 50%, and the communication amount between the hot water side auxiliary pipe component 18 (hot water supply path) and the hot water inflow hole 35 is also 50%. At this time, the cold and hot mixed water output through the cold and hot water outflow hole 36 and the cold and hot water outflow path is cold water: 50%, hot water: 50% (flow rate is 100%).

At this time, the cold and hot mixed water output through the cold and hot water outflow hole 36 and the cold and hot water outflow path is cold water: 0%, hot water: 100% (flow rate is 100%).

[0245] Fig.11E Schematically, there are Fig. 11CFrom the state of the cold water supply hole 36, the shaft body 20 and the cylindrical body 30 change the axial position by further rotating the second operating part 51, and then the cold water side auxiliary pipe component 16 (cold water supply path) and the cold water inlet hole 34 are connected at a rate of 45%, and the hot water side auxiliary pipe component 18 (hot water supply path) and the hot water inlet hole 35 are connected at a rate of 55%. At this time, the cold and hot mixed water outputted through the cold and hot water outflow hole 36 and the cold and hot water outflow path is cold water: 45%, hot water: 55% (flow rate is 100%).

[0246] Fig.11F Schematically, there are Fig.11E , the shaft body 20 and the cylindrical body 30 change their rotational positions by further rotating the first operating part 41, and then the communication amount between the cold water side auxiliary pipe component 16 (cold water supply path) and the cold water inlet hole 34 is 22.5%, and the communication amount between the hot water side auxiliary pipe component 18 (hot water supply path) and the hot water inlet hole 35 is 27.5%. At this time, the cold and hot mixed water output through the cold and hot water outflow hole 36 and the cold and hot water outflow path is cold water: 45%, hot water: 55%, but the flow rate is 50%.

[0247] Fig.11G Schematically, there are Fig.11F , the shaft body 20 and the cylindrical body 30 change their rotational positions by further rotating the first operating part 41, and the connection between the cold water side auxiliary pipe component 16 (cold water supply path) and the cold water inlet hole 34 is cut off, and the connection between the hot water side auxiliary pipe component 18 (hot water supply path) and the hot water inlet hole 35 is also cut off. At this time, the cold and hot mixed water output through the cold and hot water outflow hole 36 and the cold and hot water outflow path is cold water: 0%, hot water: 0% (that is, the flow rate is 0%).

[0248] like FIG. 11A to FIG. 11G As shown, in this modified example, by the rotation operation of the second operating part 51, the ratio of the communication volume between the cold water side auxiliary pipe component 16 (cold water supply path) and the cold water inlet hole 34 and the communication volume between the hot water side auxiliary pipe component 18 (hot water supply path) and the hot water inlet hole 35 is changed, thereby achieving temperature adjustment, and by the rotation operation of the first operating part 41, the total communication volume of the sum of the communication volume between the cold water side auxiliary pipe component 16 (cold water supply path) and the cold water inlet hole 34 and the communication volume between the hot water side auxiliary pipe component 18 (hot water supply path) and the hot water inlet hole 35 is changed, thereby achieving flow adjustment.

[0249] (Basic Effect)

[0250] As described above, according to the faucet valve device 100 of this embodiment, since both temperature adjustment and flow rate adjustment can be achieved according to the axial position and rotational position of the common cylindrical body 30, a compact faucet valve design can be achieved. In addition, since there is no obstacle to the motorization of the first operating part 41 and the motorization of the second operating part 51, it is suitable for achieving the motorization of both temperature adjustment and flow rate adjustment.

[0251] In addition, according to the faucet valve device 100 of the present embodiment, the first operating part 41 is rotated to change the ratio of the communication volume between the cold water side auxiliary pipe part 16 (cold water supply path) and the cold water inflow hole 34 and the communication volume between the hot water side auxiliary pipe part 18 (hot water supply path) and the hot water inflow hole 35, thereby achieving temperature adjustment. Moreover, the second operating part 51 is rotated to change the total communication volume of the cold water side auxiliary pipe part 16 (cold water supply path) and the cold water inflow hole 34 and the hot water side auxiliary pipe part 18 (hot water supply path) and the hot water inflow hole 35, thereby achieving flow adjustment.

[0252] However, the functions of the first operating part 41 and the second operating part 51 may be exchanged by changing the position of the cold water inlet hole 34 and the position of the hot water inlet hole 35 on the cylindrical body 30. That is, by rotating the second operating part 51, the ratio of the communication amount between the cold water side auxiliary pipe component 16 (cold water supply path) and the cold water inlet hole 34 and the communication amount between the hot water side auxiliary pipe component 18 (hot water supply path) and the hot water inlet hole 35 is changed to achieve temperature adjustment, and by rotating the first operating part 41, the total communication amount of the total communication amount between the cold water side auxiliary pipe component 16 (cold water supply path) and the cold water inlet hole 34 and the communication amount between the hot water side auxiliary pipe component 18 (hot water supply path) and the hot water inlet hole 35 is changed to achieve flow adjustment.

[0253] Furthermore, according to the faucet valve device 100 of the present embodiment, the shaft body 20 is provided, the shaft body 20 can change the rotational position without changing the axial position by the rotation operation of the first operating part 41, and can change the axial position without changing the rotational position by the rotation operation of the second operating part 51, and the cylindrical body 30 is fixed (connected) to the shaft body 20. Thus, by the control for changing the position of the shaft body 20, the control for changing the position of the cylindrical body 30 is realized with a relatively simple structure.

[0254] In addition, according to the faucet valve device 100 of the present embodiment, the first operating part 41 and the second operating part 51 can be rotated at the same time. When the first operating part 41 and the second operating part 51 are rotated at the same time, the shaft body 20 and the cylindrical body 30 change their axial positions and rotational positions. Therefore, by operating the first operating part 41 and the second operating part 51 at the same time, more rapid temperature adjustment and flow rate adjustment can be achieved.

[0255] Furthermore, according to the faucet valve device 100 of the present embodiment, a sliding cylinder 43 is provided as a first connecting member, and the sliding cylinder 43 is fixed (connected) to the shaft body 20 and fixed in the rotational direction relative to the first operating part 41, and the sliding cylinder 43 is movable in the axial direction relative to the first operating part 41. Thus, the rotational operation of the first operating part 41 can be reliably transmitted as the rotational force of the shaft body 20, and on the other hand, the existence of the sliding cylinder 43 (first connecting member) does not hinder the operation of the second operating part 51.

[0256] Furthermore, according to the faucet valve device 100 of the present embodiment, a rotating cylinder 52 as a direction conversion component, a screw body 53 as a second connection component, and a retaining ring 58 are provided. The direction conversion component can convert the rotational operation force of the second operating part 51 into an axial movement force, and the second connection component is fixed in the axial direction while allowing relative rotation with respect to the shaft body 20, and receives the axial movement force converted by the rotating cylinder 52. Thus, the rotational operation of the second operating part 51 can be reliably transmitted as the axial movement force of the shaft body 20.

[0257] Furthermore, according to the faucet valve device 100 of the present embodiment, the protruding area 54p of the retaining ring 54 is provided as a limiting member, and the limiting member can adjust the rotational movable area of ​​the second operating portion 51 to a desired range. Thus, since the movable area of ​​the axial position of the cylindrical body 30 relative to the housing 10 can be adjusted by adjusting the rotational movable area of ​​the second operating portion 51 by the protruding area 54p of the retaining ring 54, the desired flow rate adjustment or temperature adjustment can be achieved even when there is a difference between each individual due to manufacturing tolerances and the like in each component.

[0258] (Effect of opening to the atmosphere)

[0259] In addition, according to the faucet valve device 100 of the present embodiment, the shaft body 20 passes through the cylindrical body 30 in the axial direction, and both ends of the shaft body 20 are located in a region that is not connected to the internal space of the housing 10 and is open to the atmosphere. As a result, the influence of the water pressure in the internal space of the housing 10 on the shaft body 20 can be significantly suppressed. Therefore, the torque (force) required to rotate or axially move the shaft body 20 can be small, that is, it is very easy to realize motorization.

[0260] In particular, according to the faucet valve device 100 of the present embodiment, the left end of the shaft body 20 is blocked by the resin sliding bearing (bushing) 46b and the X-shaped seal ring 47b so as not to communicate with the internal space of the housing 10, and the right end of the shaft body 20 is blocked by the resin sliding bearing (bushing) 56b and the X-shaped seal ring 57b so as not to communicate with the internal space of the housing 10. Therefore, the influence of the water pressure in the internal space of the housing 10 on the shaft body 20 can be extremely effectively suppressed. In addition, the diameters of the portions of the left and right ends of the shaft body 20 that are blocked so as not to communicate with the internal space of the housing 10 are configured to be equal so as to offset the acting water pressure.

[0261] Furthermore, according to the faucet valve device 100 of this embodiment, even if the axial position of the shaft body 20 is changed by the rotation operation of the second operating part 51, both ends of the shaft body 20 are maintained in a state of being open to the atmosphere. Therefore, even if the axial position of the shaft body 20 is changed, the torque required on each of the first operating part 41 and the second operating part 51 can be small, that is, it is very easy to realize motorization.

[0262] In addition, according to the faucet valve device 100 of the present embodiment, a left cover member 47 and a right cover member 57 are provided to partition the internal space of the housing 10. Thus, by removing the left cover member 47 and / or the right cover member 57, the internal parts of the housing 10 can be easily assembled or disassembled (for example, for maintenance, etc.).

[0263] Furthermore, according to the faucet valve device 100 of this embodiment, the left cover member 47 and the right cover member 57 are respectively located inward of the axial end of the housing 10. This can reduce the length of the shaft body 20, and facilitates the compactness of the faucet valve device 100.

[0264] Furthermore, according to the faucet valve device 100 of the present embodiment, the housing 10 and the cylindrical body 30 are in direct contact with each other to have a certain degree of sealing, and there is no elastic member (so-called sealing ring) made of rubber between the housing 10 and the cylindrical body 30. As a result, the movement of the cylindrical body 30 inside the housing 10 is less likely to be undesirably hindered. This can also contribute to reducing the torque (force) for changing the axial position and rotational position of the cylindrical body 30.

[0265] (Effects of cold water side auxiliary pipe parts and hot water side auxiliary pipe parts)

[0266] Furthermore, according to the faucet valve device 100 of the present embodiment, since the cold water side auxiliary pipe member 16 can abut against the peripheral wall 33 of the cylindrical body 30 and communicate with the cold water inflow hole 34 according to the water pressure difference between one side and the other side thereof, and similarly, the hot water side auxiliary pipe member 18 can abut against the peripheral wall 33 of the cylindrical body 30 and communicate with the hot water inflow hole 35 according to the water pressure difference between one side and the other side thereof, the cold water supply and the hot water supply from the inside of the cylindrical body 30 can be surely assisted without inserting a rubber elastic member between the housing 10 and the cylindrical body 30. This can also contribute to reducing the torque (force) for changing the axial position and the rotational position of the cylindrical body 30.

[0267] Furthermore, according to the faucet valve device 100 of the present embodiment, the cold water side auxiliary pipe member 16 has a cold water side movement restriction portion that restricts the slidable stroke relative to the cold water supply path, and the hot water side auxiliary pipe member 18 has a hot water side movement restriction portion that restricts the slidable stroke relative to the hot water supply path. Thus, the movement strokes of the cold water side auxiliary pipe member 16 and the hot water side auxiliary pipe member 18 can be restricted within a desired range to prevent excessive protrusion toward the cylindrical body 30.

[0268] In particular, according to the faucet valve device 100 of this embodiment, the cold water side movement restriction part is provided as the flange part 16f having a flange shape, and the hot water side movement restriction part is also provided as the flange part 18f having a flange shape. Thus, the cold water side movement restriction part and the hot water side movement restriction part are provided relatively simply.

[0269] Furthermore, according to the faucet valve device 100 of the present embodiment, the hardness of the upper surface 16r of the cold 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 cylindrical body 30. Thus, it is possible to suppress the occurrence of undesirable wear of the cylindrical body 30. On the other hand, it is more preferable that the upper surface 16r of the cold water side auxiliary pipe member 16 and the upper surface 18r of the hot water side auxiliary pipe member 18 wear in a manner conforming to the peripheral wall 33 of the cylindrical body 30.

[0270] In particular, according to the faucet valve device 100 of the present embodiment, the peripheral wall 33 of the cylindrical body 30 is a cylindrical surface having a specified radius of curvature, the surface 16r on the upper side of the cold water side auxiliary pipe component 16 is a part of the cylindrical surface having a specified radius of curvature, and the surface 18r on the upper side of the hot water side auxiliary pipe component 18 is a part of the cylindrical surface having a specified radius of curvature, and the curvature radius of the surface 16r on the upper side of the cold water side auxiliary pipe component 16 and the curvature radius of the surface 18r on the upper side of the hot water side auxiliary pipe component 18 are larger than the curvature radius of the peripheral wall 33 of the cylindrical body 30. In this way, it is possible to avoid a state in which only the two end portions of the upper side surface 16r of the cold water side auxiliary pipe component 16 and the upper side surface of the hot water side auxiliary pipe component 18 in the arc-shaped direction abut against the cylindrical body 30 (ensuring a state in which the central portion in the arc-shaped direction abuts against the cylindrical body 30) so that the upper side surface 16r of the cold water side auxiliary pipe component 16 and the cylindrical body 30 can be well fitted, and similarly, the upper side surface 18r of the hot water side auxiliary pipe component 18 and the cylindrical body 30 can also be well fitted.

[0271] In addition, the faucet valve device 100 of the present embodiment is provided with a hot and cold water stop portion for stopping the hot and cold water. Thus, even when the minimum flow rate is adjusted only by the flow adjustment function, in the case of incomplete water stopping (insufficient sealing function in the partition control state), a reliable water stopping function can be ensured.

[0272] In particular, according to the faucet valve device 100 of the present embodiment, the hot and cold water stop parts are composed of a cold water stop part 11s arranged on the upstream side of the cold water supply path and a hot water stop part 13s arranged on the upstream side of the hot water supply path, thereby preventing hot water or cold water from flowing back to the upstream side of the other party.

[0273] Next, a faucet valve device according to a second embodiment of the present invention will be described with reference to the drawings. The faucet valve device 200 of the present embodiment is an electric faucet valve device suitable for realizing temperature adjustment.

[0275] like Figures 12 to 17 As shown, the faucet valve device 200 of the second embodiment includes: a cylindrical body 230 configured in a hollow cylindrical shape; and a housing that rotatably accommodates the cylindrical body 230.

[0276] (Cylinder 230)

[0277] The cylindrical body 230 has an outer diameter of 15 mm, a wall thickness of 0.5 mm, an axial length of 50 mm, and is formed of stainless steel. When the cylindrical body 230 is formed of a resin material, it is preferable to make the wall thickness thicker.

[0278] Especially refer to Fig.16 A right end wall 231 made of resin is fitted on the right end of the cylindrical body 230 , and a left end wall 232 made of resin is fitted on the left end of the cylindrical body 230 .

[0279] A substantially rectangular cold water inlet hole 234 is provided in the right region of the peripheral wall 233 of the cylindrical body 230. The cold water inlet hole 234 opens at, for example, a circumferential angle (angle measured around the axis) of 0° (as a reference for the following description of the angular position) to 90°, and is formed in a region at a certain distance from the right end of the cylindrical body 230 in the axial direction.

[0280] A substantially rectangular hot water inlet hole 235 is provided in the left region of the peripheral wall 233 of the cylindrical body 230. The hot water inlet hole 235 opens at, for example, a circumferential angle (angle measured around the axis) of 90° to 180° (i.e., opens at an angular position different from that of the cold water inlet hole 234), and is formed in a region at a certain distance from the left end of the cylindrical body 230 in the axial direction.

[0281] A hot and cold water outflow hole 236 is provided in a substantially axially central region of the peripheral wall 233 of the cylindrical body 230 .

[0282] In addition, the cylindrical body 230 of this embodiment has a central tube portion 237 extending from the right end wall 231 to the left end wall 232. A partition wall 238 (also see FIG. 238 ) extending radially outward from the central tube portion 237 is provided at an axial position corresponding to the hot and cold water outflow hole 236 of the cylindrical body 230. Fig.17 ).

[0283] (Axis 220)

[0284] Then, the shaft body 220 passes through the center tube portion 237 and is fixed by the right end wall 231 and the left end wall 232. Thus, the shaft body 220 and the cylindrical body 230 can rotate integrally. The shaft body 220 is, for example, φ3 and is made of stainless steel.

[0285] (Housing 210)

[0286] The inner space of the housing 210 accommodating the cylindrical body 230 is, for example, a cylindrical space, and a gap is provided between the housing 210 and the peripheral wall 233 of the cylindrical body 230. The housing 210 is also formed of stainless steel. On the other hand, the housing 210 has a substantially square columnar appearance and is formed of PPS resin.

[0287] Especially refer to Fig.15 and Fig.16 The left end of the internal space of the housing 210 is divided by a left cover member 247. The left cover member 247 is a substantially disc-shaped member and is fitted into the inner peripheral step surface of the housing 210 via an O-ring 247a. In addition, the left cover member 247 is provided with a through hole for passing the shaft body 220 in the central portion. The through hole is sealed by an X-shaped sealing ring 247b while allowing the shaft body 220 to rotate.

[0288] Similarly, the right end of the internal space of the housing 210 is divided by the right side cover member 257. The right side cover member 257 is a substantially disc-shaped member, and is fitted into the inner peripheral step surface of the housing 210 via an O-ring 257a. In addition, the right side cover member 257 is provided with a through hole for passing the shaft body 220 in the central portion. The through hole is sealed by an X-shaped sealing ring 257b while allowing the shaft body 220 to rotate.

[0289] In addition, a cold water supply path, a hot water supply path, and cold and hot water outflow paths are provided on the housing 210 so as to communicate with the internal space thereof.

[0290] Specifically, the hot and cold water outflow path of this embodiment is provided by the hot and cold water outflow outlet 215 integrated with the housing 210. The hot and cold water outflow outlet 215 opens toward the upper side of the housing 210 and is connected to the hot and cold water supply pipe 263 via an elbow connection pipe 262, for example.

[0291] In addition, the cold and hot water outflow outlet 215 is set at a size and position so that the cold and hot water outflow holes 236 of the cylindrical body 230 can all be connected when the cylindrical body 230 is in any position and posture within the movable area.

[0292] On the other hand, the cold water supply route of this embodiment is provided by a cold water supply pipe 211 that can be removed from the housing 210, and a cold water side communication hole 212 that communicates the cold water supply pipe 211 with the internal space of the housing 210. The cold water supply pipe 211 is fitted into a connection port 211r provided on the lower surface of the housing 210 via an O-ring. The cold water supply pipe 211 side of the cold water side communication hole 212 is a circular cross-section hole, and the internal space side of the housing 210 is a rectangular cross-section hole that converges within the circular cross-section.

[0293] Similarly, the hot water supply route of this embodiment can be provided by a hot water supply pipe 213 that can be removed from the housing 210, and a hot water side communication hole 214 that communicates the hot water supply pipe 213 with the internal space of the housing 210. Like the cold water supply pipe 211, the hot water supply pipe 213 is also fitted into a connection port 213r provided on the lower surface of the housing 210 via an O-ring. Like the cold water side communication hole 212, the hot water side communication hole 214 is also a circular cross-section hole on the hot water supply pipe 213 side, and the internal space side of the housing 210 is a rectangular cross-section hole that converges within the circular cross-section.

[0294] (Auxiliary pipe parts 216, 218)

[0295] Then, the lower side (an example of one side) of the cold water side auxiliary pipe component 216 is accommodated inside the cold water side connecting hole 212. The cold water side auxiliary pipe component 216 can slide upward or downward inside the cold water side connecting hole 212 according to the water pressure difference between its lower side and upper side (an example of the other side). Specifically, a sealing ring 217 (cold water side sealing component) is inserted between the cold water side connecting hole 212 and the cold water side auxiliary pipe component 216, and the sealing ring 217 holds the cold water side auxiliary pipe component 216 so that it can slide upward or downward relative to the cold water side connecting hole 212. Moreover, when the cold water side auxiliary pipe component 216 moves upward, the upper side (an example of the other side) of the cold water side auxiliary pipe component 216 can abut against the peripheral wall 233 of the cylindrical body 230, and can be connected to the cold water inlet hole 234.

[0296] Fig.18 2 is a schematic perspective view of the cold water side auxiliary pipe component 216 of this embodiment. Fig.18 As shown, the cold water side auxiliary pipe component 216 of the present embodiment has a flange portion 216f as a cold water side movement limiting portion, which can limit the sliding stroke relative to the inside of the cold water side connecting hole 212. The flange portion 216f is accommodated in the circular cross-sectional hole on the cold water supply pipe 211 side of the cold water side connecting hole 212, and has a size that does not enter the rectangular cross-sectional hole of the cold water side connecting hole 212, so that the movement of the cold water side auxiliary pipe component 216 is limited by the abutment of the flange portion 216f. In the present embodiment, the sliding stroke of the cold water side auxiliary pipe component 216 is 1 mm. In addition, the cold water side auxiliary pipe component 216 has a groove portion 16g for fitting the sealing ring 217.

[0297] like Fig.18As shown, at the time of shipment (before use), the upper surface 216r of the cold water side auxiliary pipe member 216 is a part of a cylindrical surface with a curvature radius of 10 mm (preferably in the range of 5 mm to 15 mm). That is, the curvature radius is slightly larger than the curvature radius (8.5 mm) of the peripheral wall 233 of the cylindrical body 230. Thus, it is possible to avoid a state in which only the two ends of the arc-shaped direction of the upper surface 216r of the cold water side auxiliary pipe member 216 abut against the cylindrical body 230 (a state produced when the magnitude relationship of the curvature radius is opposite), that is, it is possible to ensure that the central part of the arc-shaped direction of the upper surface 216r of the cold water side auxiliary pipe member 216 abuts against the cylindrical body 230, so that the upper surface 216r of the cold water side auxiliary pipe member 216 and the cylindrical body 230 have good fit.

[0298] Furthermore, the hardness of the cold water side auxiliary pipe member 216 (at least the upper surface) is smaller than the hardness of the peripheral wall 233 of the cylindrical body 230. Thus, it is possible to suppress the occurrence of undesired wear of the peripheral wall 233 of the cylindrical body 230, and on the other hand, it is expected that the upper surface 216r of the cold water side auxiliary pipe member 216 will wear in a manner conforming to the peripheral wall 233 of the cylindrical body 230, which is appropriate for the close fit between the upper surface 216r of the cold water side auxiliary pipe member 216 and the cylindrical body 230. On the other hand, since the flange portion 216f, which is a cold water side movement restriction portion, restricts the amount of movement, it is possible to suppress excessive wear.

[0299] The magnitude of the hardness can be determined, for example, by Vickers hardness, which can be obtained by a test specified by ISO International Standard 6507 (JIS Japanese Industrial Standard Z 2244). The cold water side auxiliary pipe member 216 of this embodiment is made of polyacetal resin, and its hardness is significantly lower than that of the peripheral wall 233 of the stainless steel cylinder 230.

[0300] The size and position (in the axial direction of the housing 210) of the tube hole 216h of the cold water side auxiliary pipe member 216 are such that the tube hole 216h can be connected to the entire cold water inlet hole 234 when the amount of communication between the cold water side auxiliary pipe member 216 and the cold water inlet hole 234 is controlled to be maximum (see the following description). Fig.19 and Figures 20A-20D ).

[0301] Similarly, the lower side (an example of one side) of the hot water side auxiliary pipe component 218 is accommodated inside the hot water side connecting hole 214. The hot water side auxiliary pipe component 218 can slide upward or downward inside the hot water side connecting hole 214 according to the water pressure difference between its lower side and upper side (an example of the other side). Specifically, a sealing ring 219 (hot water side sealing component) is inserted between the hot water side connecting hole 214 and the hot water side auxiliary pipe component 218, and the sealing ring 219 holds the hot water side auxiliary pipe component 218 so that it can slide upward or downward relative to the hot water side connecting hole 214. Moreover, when the hot water side auxiliary pipe component 218 moves upward, the upper side (an example of the other side) of the hot water side auxiliary pipe component 218 can abut against the peripheral wall 233 of the cylindrical body 230, and can be connected to the hot water inlet hole 235.

[0302] Fig.18 This is also a schematic three-dimensional diagram of the hot water side auxiliary pipe component 218 of this embodiment. Fig.18 As shown, the hot water side auxiliary pipe component 218 of this embodiment also has a flange portion 218f as a hot water side movement limiting portion, which can limit the sliding stroke relative to the inside of the hot water side connecting hole 214. The flange portion 218f is accommodated in the circular cross-sectional hole on the hot water supply pipe 213 side of the hot water side connecting hole 214, and has a size that does not enter the rectangular cross-sectional hole of the hot water side connecting hole 214, so that the movement of the hot water side auxiliary pipe component 218 is limited by the abutment of the flange portion 218f. In this embodiment, the sliding stroke of the hot water side auxiliary pipe component 218 is 5mm. In addition, the hot water side auxiliary pipe component 218 has a groove portion 218g for fitting the sealing ring 219.

[0303] like Fig.18 As shown, at the time of shipment (before use), the upper surface 218r of the hot water side auxiliary pipe component 218 also becomes a part of the cylindrical surface with a curvature radius of 10 mm (preferably in the range of 5 mm to 15 mm). That is, the curvature radius is slightly larger than the curvature radius (8.5 mm) of the peripheral wall 233 of the cylindrical body 230. As a result, it is possible to avoid a state in which only the two ends of the arc-shaped direction of the upper surface 218r of the hot water side auxiliary pipe component 218 abut against the cylindrical body 230 (a state produced when the magnitude relationship of the curvature radii is opposite), that is, it is possible to ensure that the central part of the arc-shaped direction of the upper surface 218r of the hot water side auxiliary pipe component 218 abuts against the cylindrical body 230, so that the upper surface 218r of the hot water side auxiliary pipe component 218 and the cylindrical body 230 have good fit.

[0304] Furthermore, the hardness of the hot water side auxiliary pipe member 218 (at least the upper surface) is also lower than the hardness of the peripheral wall 233 of the cylindrical body 230. Thus, it is possible to suppress the occurrence of undesired wear of the peripheral wall 233 of the cylindrical body 230, and on the other hand, it is expected that the upper surface 218r of the hot water side auxiliary pipe member 218 will wear in a manner conforming to the peripheral wall 233 of the cylindrical body 230, which is appropriate for the close fit between the upper surface 218r of the hot water side auxiliary pipe member 218 and the cylindrical body 230. On the other hand, since the flange portion 218f, which is a hot water side movement restriction portion, restricts the amount of movement, it is possible to suppress excessive wear.

[0305] The hot water side auxiliary pipe member 218 of the present embodiment is also made of polyacetal resin, and has a hardness significantly lower than the hardness of the peripheral wall 233 of the cylindrical body 230 made of stainless steel.

[0306] The size and position (in the axial direction of the housing 210) of the pipe hole 218h of the hot water side auxiliary pipe member 218 are such that the pipe hole 218h can be connected to the entire hot water inlet hole 235 when the communication amount between the hot water side auxiliary pipe member 218 and the hot water inlet hole 235 is controlled to be maximum (see the following description). Figures 20A-20D ).

[0307] (Operating mechanism 240)

[0308] like Figures 12 to 15 As shown, an operating mechanism 240 is provided on the left side (axial side) of the cylindrical body 230. The operating mechanism 240 has an operating portion 241 that is configured to be rotatable. In this embodiment, the operating portion 241 is a stepping motor that receives a control command from a control body portion (not shown) and can perform a rotational operation according to the control command.

[0309] In this embodiment, the shaft body 220 and the cylindrical body 230 can change the rotational position through the rotation operation of the operating portion 241 without changing the axial position.

[0310] Specifically, especially Fig.15 As shown, the rotating shaft (output shaft) 241s of the operating part 241 is fixed in both the axial direction and the rotation direction at the bottom of the rotating cylinder 242. The rotating cylinder 242 is arranged with its bottom located on the left side and is held in the outer cylinder 245 so as to be rotatable around the axis.

[0311] The outer shell 245 also holds the main body of the operating part 241 (the position near the rotating shaft 241s) via the retaining ring 244 on its left side. In addition, the outer shell 245 is connected (engaged) to the left end of the housing 210 and the left cover member 247 via the connecting ring 246 on its right side. A resin sliding bearing (bushing) 246b (see FIG. 246 ) is provided at the center of the connecting ring 246 for passing through the shaft body 220. Fig.16 ).

[0312] The right side (opposite to the bottom) of the rotating cylinder 242 is open, and a sliding cylinder 243 that can slide in the axial direction is embedded therein, and the rotating cylinder 242 and the sliding cylinder 243 are fixed in the rotation direction. For example, the sliding cylinder 243 has four protrusions protruding in a cross shape in the axial section, and the rotating cylinder 242 has four recesses that accommodate the four protrusions in a manner that can slide in the axial direction. That is, the four protrusions are respectively accommodated in the four recesses, and when the rotating cylinder 242 rotates, the sliding cylinder 243 also rotates. When the sliding cylinder 243 rotates, the shaft body 220 and the cylindrical body 230 also rotate. On the other hand, the sliding cylinder 243 is accommodated in the rotating cylinder 242 and is not fixed in the axial direction relative to the rotating cylinder 242. That is, even if the shaft body 220 moves in the axial direction, the rotating cylinder 242 can be suppressed from moving in the axial direction, or it can be idle relative to the rotating cylinder 242 without applying force in the axial direction.

[0313] The slide cylinder 243 is fixed to the left end of the shaft body 220. Thus, the slide cylinder 243 is fixed in the rotation direction relative to the rotation axis 241s of the operation part 241 as a connection member, and is movable in the axial direction relative to the rotation axis 241s of the operation part 241.

[0314] In this embodiment, the operating portion 241 can provide a maximum rotation operation of 90°+α.

[0315] (Supporting mechanism 250)

[0316] On the other hand, a support mechanism 250 is provided on the right side (the other side in the axial direction) of the cylindrical body 230. The support mechanism 250 supports the shaft body 220 and the cylindrical body 230 so as to be rotatable without changing the axial position.

[0317] Specifically, the outer casing 255 is provided substantially bilaterally symmetrically with the outer casing 245. The outer casing 255 holds the right end of the shaft body 220 via a pair of retaining rings 258. Thus, the outer casing 255 and the shaft body 220 are rotatable with each other but are fixed in the axial direction.

[0318] In addition, the outer shell tube 255 is connected (engaged) to the right end of the housing 210 and the right cover member 257 via a connecting ring 256 on its left side. A resin sliding bearing (bushing) 256b (see FIG. 25) is also provided at the center of the connecting ring 256 for passing the shaft body 220. Fig.16 ).

[0319] (Both ends of the shaft 220)

[0320] According to the above-mentioned structure, both ends of the shaft body 220 of the present embodiment are located in a region that is isolated from the internal space of the housing 210 and is open to the atmosphere (subject to atmospheric pressure instead of water pressure).

[0321] Specifically, the left end of the shaft body 220 is separated by a resin sliding bearing (bushing) 246b and an X-shaped sealing ring 247b, so that it will not be connected to the internal space of the shell 210. The right end of the shaft body 220 is separated by a resin sliding bearing (bushing) 256b and an X-shaped sealing ring 257b, so that it will not be connected to the internal space of the shell 210.

[0322] Thus, the influence of the water pressure in the inner space of the housing 210 on the shaft 220 can be significantly suppressed. Therefore, the torque (force) required to rotate the shaft 220 (and the cylindrical body 230) can be smaller, that is, the torque required on the operating part 241 can be smaller. It is better if the diameters of the cut-off parts of the shaft 220 are the same.

[0323] In addition, although the housing 210 has a left cover member 247 and a right cover member 257 to divide the internal space, by removing these cover members 247 and 257, the internal parts of the housing 210 can be easily assembled or disassembled (for example, for maintenance, etc.).

[0324] Furthermore, in the present embodiment, the cover members 247 and 257 of the housing 210 are respectively located inward of the axial end portions of the housing 210 , so that the length of the shaft body 220 can be suppressed.

[0325] (Water stop function)

[0326] In addition, the faucet valve device 200 of the present embodiment is also provided with a cold and hot water stop portion for stopping the flow of cold and hot water. Specifically, the cold and hot water stop portion includes a cold water stop portion 211s disposed on the upstream side of the cold water supply path, and a hot water stop portion 213s disposed on the upstream side of the hot water supply path (see Fig.13 ). This prevents hot water or cold water from flowing back to the upstream side of the other side.

[0327] (Function of the faucet valve device 200)

[0328] Next, the operation of the faucet valve device 200 according to the present embodiment will be described.

[0329] According to the above-mentioned configuration, the cylindrical body 230 of the present embodiment can change the rotational position by the rotation operation of the operation portion 241 without changing the axial position.

[0330] Furthermore, temperature adjustment can be achieved by changing the amount of communication between the cold water side auxiliary pipe component 216 (cold water supply path) and the cold water inlet hole 234 and the amount of communication between the hot water side auxiliary pipe component 218 (hot water supply path) and the hot water inlet hole 235 according to the rotation position of the cylinder 230. In this embodiment, the cold and hot water outflow hole 236 and the cold and hot water outflow path are always maintained in a good communication state. Fig.19 This is a schematic diagram showing a state in which the cold water side auxiliary pipe member 216 and the hot water side auxiliary pipe member 218 according to the present embodiment are in contact with the cylindrical body 230 .

[0331] In this embodiment, by rotating the operating part 241, the ratio of the communication volume between the cold water side auxiliary pipe component 216 (cold water supply path) and the cold water inlet hole 234 and the communication volume between the hot water side auxiliary pipe component 218 (hot water supply path) and the hot water inlet hole 235 will change, thereby achieving temperature adjustment.

[0332] FIG. 20A to FIG. 20D 2 is a schematic diagram for explaining the position control of the cylindrical body 230 in this embodiment. In this embodiment, the temperature can be adjusted according to the rotation position of the cylindrical body 230.

[0333] Fig. 20A The positions of the cold water inlet 234 and the hot water inlet 235 on the peripheral wall 233 of the cylindrical body 230 are schematically shown.

[0334] Fig. 20B The schematic diagram shows a state in which the communication between the cold water side auxiliary pipe member 216 (cold water supply path) and the cold water inflow hole 234 is at a maximum, and the communication between the hot water side auxiliary pipe member 218 (hot water supply path) and the hot water inflow hole 235 is cut off. At this time, the cold and hot mixed water output through the cold and hot water outflow hole 236 and the cold and hot water outflow path is cold water: 100%, hot water: 0%.

[0335] Fig. 20C Schematically, there are Fig. 20B The shaft 220 and the cylindrical body 230 change their rotational positions by rotating the operating unit 241, and the cold water side auxiliary pipe component 216 (cold water supply path) and the cold water inflow hole 234 are connected at 50%, and the hot water side auxiliary pipe component 218 (hot water supply path) and the hot water inflow hole 235 are connected at 50%. At this time, the cold and hot mixed water outputted through the cold and hot water outflow hole 236 and the cold and hot water outflow path is cold water: 50%, hot water: 50%.

[0336] Fig.20D Schematically, there are Fig. 20CFrom the state, the shaft body 220 and the cylindrical body 230 change the rotational position by further rotating the operating part 241, and then the connection between the cold water side auxiliary pipe component 216 (cold water supply path) and the cold water inflow hole 234 is cut off, and the connection amount between the hot water side auxiliary pipe component 218 (hot water supply path) and the hot water inflow hole 235 is the maximum. At this time, the cold and hot mixed water output through the cold and hot water outflow hole 236 and the cold and hot water outflow path is cold water: 0%, hot water: 100%.

[0337] (Basic Effect)

[0338] As described above, according to the faucet valve device 200 of the present embodiment, since the temperature can be adjusted according to the rotation position of the cylindrical body 230, a compact faucet valve design can be achieved.

[0339] Furthermore, the faucet valve device 200 according to the present embodiment does not hinder the motorization of the operation portion 241 and is therefore suitable for realizing the motorization of temperature adjustment.

[0340] Furthermore, according to the faucet valve device 200 of this embodiment, the shaft body 220 is provided to penetrate the cylindrical body 230 in the axial direction and is fixed (connected) to the cylindrical body 230. Thus, the position of the cylindrical body 230 can be controlled by a relatively simple structure of controlling the position of the shaft body 220 to realize control.

[0341] Furthermore, according to the faucet valve device 200 of the present embodiment, a sliding cylinder 243 as a connecting member is provided which is fixed (connected) to the left end of the shaft body 220 and is fixed in the rotational direction relative to the operating part 241, and the sliding cylinder 243 is movable in the axial direction relative to the operating part 241. Thus, the rotational operation of the operating part 241 can be reliably transmitted as the rotational force of the shaft body 220, and on the other hand, the force that can act on the shaft body 220 in the axial direction does not hinder the operation of the operating part 241.

[0342] In addition, according to the faucet valve device 200 of the present embodiment, a support mechanism 250 is provided, and the support mechanism 250 restricts the axial movement of the right end of the shaft body 220, while not restricting the rotation of the right end of the shaft body 220. Thus, while restricting the axial movement of the right end of the shaft body 220, it is also possible to suppress the situation where the rotation of the shaft body 220 is hindered and the operation of the operating part 241 is hindered.

[0343] (Effect of opening to the atmosphere)

[0344] In addition, according to the faucet valve device 200 of the present embodiment, the shaft body 220 passes through the cylindrical body 230 in the axial direction, and both ends of the shaft body 220 are located in a region that is not connected to the internal space of the housing 210 and are open to the atmosphere. As a result, the influence of the water pressure in the internal space of the housing 210 on the shaft body 220 can be significantly suppressed. Therefore, the torque (force) required to rotate the shaft body 220 can be small, that is, it is very easy to realize motorization.

[0345] In particular, according to the faucet valve device 200 of the present embodiment, the left end of the shaft body 220 is blocked by the resin sliding bearing (bushing) 246b and the X-shaped seal ring 247b so as not to communicate with the internal space of the housing 210, and the right end of the shaft body 220 is blocked by the resin sliding bearing (bushing) 256b and the X-shaped seal ring 257b so as not to communicate with the internal space of the housing 210. Therefore, the influence of the water pressure in the internal space of the housing 210 on the shaft body 220 can be extremely effectively suppressed. In addition, the diameters of the portions of the left and right ends of the shaft body 220 that are blocked so as not to communicate with the internal space of the housing 210 are configured to be equal so as to offset the acting water pressure.

[0346] In addition, according to the faucet valve device 200 of the present embodiment, a left cover member 247 and a right cover member 257 are provided to divide the internal space of the housing 210. Thus, by removing the left cover member 247 and / or the right cover member 257, the internal parts of the housing 210 can be easily assembled or disassembled (for example, for maintenance, etc.).

[0347] Furthermore, according to the faucet valve device 200 of this embodiment, the left cover member 247 and the right cover member 257 are respectively located further inward than the axial end of the housing 210. Thus, the length of the shaft 220 can be suppressed, and the faucet valve device 200 can be made compact.

[0348] Furthermore, according to the faucet valve device 200 of the present embodiment, the housing 210 and the cylindrical body 230 are in direct contact with each other to have a certain degree of sealing, and there is no elastic member (so-called sealing ring) made of rubber between the housing 210 and the cylindrical body 230. As a result, the movement of the cylindrical body 230 inside the housing 210 is less likely to be undesirably hindered. This can also contribute to reducing the torque (force) for changing the rotational position of the cylindrical body 230.

[0349] (Effects of cold water side auxiliary pipe parts and hot water side auxiliary pipe parts)

[0350] Furthermore, according to the faucet valve device 200 of the present embodiment, since the cold water side auxiliary pipe member 216 can abut against the peripheral wall 233 of the cylindrical body 230 and communicate with the cold water inflow hole 234 according to the water pressure difference between one side and the other side thereof, and similarly, the hot water side auxiliary pipe member 218 can abut against the peripheral wall 233 of the cylindrical body 230 and communicate with the hot water inflow hole 235 according to the water pressure difference between one side and the other side thereof, the cold water supply and the hot water supply to the inside of the cylindrical body 230 can be effectively assisted without inserting a rubber elastic member between the housing 210 and the cylindrical body 230. This can also contribute to making the torque (force) for changing the rotational position of the cylindrical body 230 small.

[0351] Furthermore, according to the faucet valve device 200 of the present embodiment, the cold water side auxiliary pipe member 216 has a cold water side movement restriction portion that restricts the slidable stroke relative to the cold water supply path, and the hot water side auxiliary pipe member 218 has a hot water side movement restriction portion that restricts the slidable stroke relative to the hot water supply path. Thus, the movement strokes of the cold water side auxiliary pipe member 216 and the hot water side auxiliary pipe member 218 can be restricted within a desired range to prevent excessive protrusion toward the cylindrical body 230.

[0352] In particular, according to the faucet valve device 200 of this embodiment, the cold water side movement restriction part is provided as the flange part 216f having a flange shape, and the hot water side movement restriction part is also provided as the flange part 218f having a flange shape. Thus, the cold water side movement restriction part and the hot water side movement restriction part are provided relatively simply.

[0353] Furthermore, according to the faucet valve device 200 of the present embodiment, the hardness of the upper surface 216r of the cold water side auxiliary pipe member 216 and the upper surface 218r of the hot water side auxiliary pipe member 218 are smaller than the hardness of the peripheral wall 233 of the cylindrical body 230. Thus, it is possible to suppress the occurrence of undesirable wear of the cylindrical body 230. On the other hand, it is more preferable that the upper surface 216r of the cold water side auxiliary pipe member 216 and the upper surface 218r of the hot water side auxiliary pipe member 218 wear in a manner conforming to the peripheral wall 233 of the cylindrical body 230.

[0354] In particular, according to the faucet valve device 200 of the present embodiment, the peripheral wall 233 of the cylindrical body 230 is a cylindrical surface having a specified radius of curvature, the surface 216r on the upper side of the cold water side auxiliary pipe component 216 is a part of the cylindrical surface having a specified radius of curvature, and the surface 218r on the upper side of the hot water side auxiliary pipe component 218 is a part of the cylindrical surface having a specified radius of curvature, and the curvature radius of the surface 216r on the upper side of the cold water side auxiliary pipe component 216 and the curvature radius of the surface 218r on the upper side of the hot water side auxiliary pipe component 218 are larger than the curvature radius of the peripheral wall 233 of the cylindrical body 230. In this way, it is possible to avoid a state in which only the two end portions of the upper side surface 216r of the cold water side auxiliary pipe component 216 and the upper side surface 218r of the hot water side auxiliary pipe component 218 in the arc-shaped direction abut against the cylindrical body 230 (ensuring a state in which the central part in the arc-shaped direction abuts against the cylindrical body 230) so that the upper side surface 216r of the cold water side auxiliary pipe component 216 and the cylindrical body 230 can be well fitted, and similarly, the upper side surface 218r of the hot water side auxiliary pipe component 218 and the cylindrical body 230 can also be well fitted.

[0355] In addition, the faucet valve device 200 of the present embodiment is provided with a hot and cold water stop portion for stopping the hot and cold water. Thus, even when the minimum flow rate is adjusted only by the flow adjustment function, in the case of incomplete water stopping (insufficient sealing function in the partition control state), a reliable water stopping function can be ensured.

[0356] In particular, according to the faucet valve device 200 of the present embodiment, the hot and cold water stopping parts are composed of a cold water stopping part 211s arranged on the upstream side of the cold water supply path and a hot water stopping part 213s arranged on the upstream side of the hot water supply path, thereby preventing hot water or cold water from flowing back to the upstream side of the other party.
