Description

[Technical field]

[0001] The present invention relates to a faucet valve device, and more particularly to a faucet valve device suitable for achieving motorized temperature adjustment. [Background technology]

[0002] The applicant of the present application has achieved motorization of the flow rate adjustment valve (Patent Document 1). [Prior art documents] [Patent documents]

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

[0004] However, no suitable faucet valve device suitable for achieving motorized temperature adjustment has yet been proposed.

[0005] The present invention has been devised in light of the above-mentioned background, and an object of the present invention is to provide a faucet valve device suitable for realizing motorized temperature adjustment. [Means for solving the problem]

[0006] The present invention relates to A cylinder body formed in a hollow cylindrical shape; A water inlet hole, a hot water inlet hole, and a hot and cold water outlet hole are provided in the peripheral wall of the cylinder body, respectively; a housing body that rotatably accommodates the cylinder body; a water supply passage, a hot water supply passage, and a hot and cold water outflow passage, each of which is provided so as to communicate with an internal space of the housing body; an operating portion provided rotatably on one axial side of the cylinder body; a shaft body that axially penetrates the cylinder body and is connected to or integrated with the cylinder body; a shaft body support member that rotatably supports the shaft body outside the cylinder body; a hot water side seal member interposed between the hot water supply passage of the housing body and the cylinder body; a water-side seal member interposed between the water supply passage of the housing body and the cylinder body; Equipped with The housing body has a receiving portion that receives the shaft body support member, a projection is provided on a part of the receiving portion, the projection being brought into contact with the shaft body support member supporting the shaft body so that the cylinder body connected to or integrated with the shaft body is biased toward the hot water side seal member and the cold water side seal member; The rotational positions of the cylinder body and the shaft body are changed by rotating the operation unit, Temperature adjustment is realized by changing the amount of communication between the water supply passage and the water inlet hole, the amount of communication between the hot water supply passage and the hot water inlet hole, and / or the amount of communication between the hot water outlet hole and the hot water outlet passage depending on the rotational position of the cylinder body. The present invention relates to a faucet valve device.

[0007] According to the present invention, a compact faucet valve design can be realized since temperature regulation is achieved depending on the rotational position of the cylinder body.

[0008] Furthermore, according to the present invention, since there is no hindrance to the motorization of the operating unit, it is suitable for realizing motorization of temperature adjustment.

[0009] The faucet valve device of the present invention also includes a shaft body that passes through the cylinder body in the axial direction and is connected to or integrated with the cylinder body.

[0010] This makes it possible to realize control for changing the position of the cylinder body with a relatively simple configuration for controlling the position of the shaft body.

[0011] In addition, in the present invention, the housing body has a receiving portion that receives the shaft body support member, and a protrusion is provided in a part of the receiving portion that abuts against the shaft body support member that supports the shaft body so that the cylinder body connected or integrated with the shaft body is urged toward the hot water side seal member and the cold water side seal member.

[0012] This makes it easy to stably ensure an appropriate seal by biasing the shaft body support member toward the hot water side seal member and the cold water side seal member, and ensures sufficient sealing performance of the hot water side seal member and the cold water side seal member. Furthermore, since the protrusion does not act on the shaft body directly but indirectly via the shaft body support member, there is little risk of an undesired increase in resistance when the shaft body rotates, and there is also no risk of the protrusion being worn down by the rotation of the shaft body. Furthermore, by ensuring these functions with the protrusion, it becomes possible to ensure a balance between the two by simply adjusting the size of the protrusion.

[0013] The present invention relates to A cylinder body formed in a hollow cylindrical shape; A water inlet hole, a hot water inlet hole, and a hot and cold water outlet hole are provided in the peripheral wall of the cylinder body, respectively; a housing body that rotatably accommodates the cylinder body; a water supply passage, a hot water supply passage, and a hot and cold water outflow passage, each of which is provided so as to communicate with an internal space of the housing body; an operating portion provided rotatably on one axial side of the cylinder body; a shaft body that axially penetrates the cylinder body and is connected to or integrated with the cylinder body; a shaft body support member that rotatably supports the shaft body outside the cylinder body; a hot water side seal member interposed between the hot water supply passage of the housing body and the cylinder body; a water-side seal member interposed between the water supply passage of the housing body and the cylinder body; Equipped with The housing body has a receiving portion that receives the shaft body support member, a projection is provided in a portion of an area of ​​the shaft body support member that is received in the receiving portion, the projection being adapted to come into contact with the receiving portion so that the cylinder body connected to or integrated with the shaft body is biased toward the hot water side seal member and the cold water side seal member when the area is received in the receiving portion; The rotational positions of the cylinder body and the shaft body are changed by rotating the operation unit, Temperature adjustment is realized by changing the amount of communication between the water supply passage and the water inlet hole, the amount of communication between the hot water supply passage and the hot water inlet hole, and / or the amount of communication between the hot water outlet hole and the hot water outlet passage depending on the rotational position of the cylinder body. The present invention relates to a faucet valve device.

[0014] According to the present invention, too, temperature regulation is achieved depending on the rotational position of the cylinder body, so that a compact faucet valve design can be achieved.

[0015] Furthermore, the present invention also allows for no hindrance to motorizing the operating section, and is therefore suitable for achieving motorized temperature adjustment.

[0016] The faucet valve device of the present invention also includes a shaft body that passes through the cylinder body in the axial direction and is connected to or integrated with the cylinder body.

[0017] This makes it possible to realize control for changing the position of the cylinder body with a relatively simple configuration for controlling the position of the shaft body.

[0018] In addition, in the present invention, the housing body has a receiving portion that receives the shaft body support member, and a protrusion is provided in a part of the area of ​​the shaft body support member that is received in the receiving portion, and the cylinder body connected to or integrated with the shaft body is urged toward the hot water side sealing member and the cold water side sealing member when the area is received in the receiving portion.

[0019] This makes it easy to stably ensure an appropriate seal by biasing the shaft body support member toward the hot water side seal member and the cold water side seal member, and ensures sufficient sealing performance of the hot water side seal member and the cold water side seal member. Furthermore, since the protrusion does not act on the shaft body directly but indirectly via the shaft body support member, there is little risk of an undesired increase in resistance when the shaft body rotates, and there is also no risk of the protrusion being worn down by the rotation of the shaft body. Furthermore, by ensuring these functions with the protrusion, it becomes possible to ensure a balance between the two by simply adjusting the size of the protrusion.

[0020] The present invention relates to A cylinder body formed in a hollow cylindrical shape; A water inlet hole, a hot water inlet hole, and a hot and cold water outlet hole are provided in the peripheral wall of the cylinder body, respectively; a housing body that rotatably accommodates the cylinder body; a water supply passage, a hot water supply passage, and a hot and cold water outflow passage, each of which is provided so as to communicate with an internal space of the housing body; an operating portion provided rotatably on one axial side of the cylinder body; a shaft body that axially penetrates the cylinder body and is connected to or integrated with the cylinder body; a shaft body support member that rotatably supports the shaft body outside the cylinder body; a hot water side seal member interposed between the hot water supply passage of the housing body and the cylinder body; a water-side seal member interposed between the water supply passage of the housing body and the cylinder body; Equipped with The housing body has a receiving portion that receives the shaft body support member, an additional positioning piece is inserted between a region of the shaft body support member that is received in the receiving portion and the receiving portion, so that when the region is received in the receiving portion, the cylinder body connected to or integrated with the shaft body is biased toward the hot water side seal member and the cold water side seal member; The rotational positions of the cylinder body and the shaft body are changed by rotating the operation unit, Temperature adjustment is realized by changing the amount of communication between the water supply passage and the water inlet hole, the amount of communication between the hot water supply passage and the hot water inlet hole, and / or the amount of communication between the hot water outlet hole and the hot water outlet passage depending on the rotational position of the cylinder body. The present invention relates to a faucet valve device.

[0021] According to the present invention, too, temperature regulation is achieved depending on the rotational position of the cylinder body, so that a compact faucet valve design can be achieved.

[0022] Furthermore, the present invention also allows for no hindrance to motorizing the operating section, and is therefore suitable for achieving motorized temperature adjustment.

[0023] The faucet valve device of the present invention also includes a shaft body that passes through the cylinder body in the axial direction and is connected to or integrated with the cylinder body.

[0024] This makes it possible to realize control for changing the position of the cylinder body with a relatively simple configuration for controlling the position of the shaft body.

[0025] In addition, in the present invention, the housing body has a receiving portion that receives the shaft body support member, and an additional positioning piece that abuts the shaft body support member and the receiving portion is inserted into a portion between the area of ​​the shaft body support member that is received in the receiving portion and the receiving portion so that the cylinder body connected to or integrated with the shaft body is urged toward the hot water side sealing member and the cold water side sealing member when the area is received in the receiving portion.

[0026] As a result, by biasing the shaft body support member toward the hot water side seal member and the water side seal member, it becomes easy to stably secure an appropriate seal margin, and sufficient sealing performance of the hot water side seal member and the water side seal member can be guaranteed. In addition, since the additional positioning piece does not act on the shaft body directly but indirectly through the shaft body support member, there is little risk of an undesired increase in resistance when the shaft body rotates, and there is also no risk of the additional positioning piece being worn down by the rotation of the shaft body. In addition, by ensuring these functions with the additional positioning piece, it becomes possible to ensure a balance between the two by adjusting only the size of the additional positioning piece. The additional positioning piece may be made of a rigid material or an elastic material, for example, in a wedge shape. In the latter case, the shaft body support member can be elastically pressed against the hot water side seal member and the water side seal member, and an appropriate seal margin can be secured even when the hot water side seal member and the water side seal member are worn down.

[0027] In each of the above-mentioned inventions, it is preferable that the shaft body support member supports the shaft body via a resin sliding bearing.

[0028] This makes it possible to effectively maintain the centering function of the shaft body, and to press the cylinder body firmly against the hot water side seal member and the cold water side seal member.

[0029] In addition, in each of the above-mentioned inventions, the protrusion or additional positioning piece does not come into contact with the rotating member, so there is little need for high wear resistance. On the other hand, since the plastic sliding bearing is an element that supports the rotating shaft body, it is preferable that it has high wear resistance. Therefore, it is preferable that the wear resistance of the plastic sliding bearing is higher than that of the protrusion or additional positioning piece.

[0030] In each of the above-mentioned inventions, it is preferable that the shaft support members are provided on both sides of the cylinder body, so that the entire cylinder body can be firmly pressed against the hot water side seal member and the cold water side seal member.

[0031] Additionally, in the present invention, it is preferable that both ends of the shaft body are in an area not communicating with the internal space of the housing body and are open to the atmosphere.

[0032] This significantly reduces the effect of water pressure in the internal space of the housing body on the shaft body.

[0033] For this reason, the torque (force) required to rotate the shaft body is small, which is very convenient for realizing motorization.

[0034] For example, the regions where both ends of the shaft body are present are blocked by seal members so as not to communicate with the internal space of the housing body.

[0035] It is also preferable that the device further comprises a connecting member that is connected or integrated with one end of the shaft body and fixed in a rotational direction relative to the operating portion, and that the connecting member is installed so as to be movable in the axial direction relative to the operating portion.

[0036] This ensures that the rotational operation of the operating part can be reliably transmitted as a rotational force of the shaft body, while at the same time preventing the operation of the operating part from being hindered by forces that may act in the axial direction of the shaft body.

[0037] It is also preferable that the shaft body further include a retaining member that restricts axial movement of the other end of the shaft body but does not restrict rotation of the other end of the shaft body.

[0038] Such a retaining member restricts axial movement of the other end of the shaft body, while preventing the rotation of the shaft body, and therefore the operation of the operating portion, from being hindered.

[0039] It is also preferable that the housing body has a cover member on one axial side and a cover member on the other axial side to partition the internal space.

[0040] According to this, by removing the cover member, it is easy to assemble or disassemble (for example, for maintenance) the parts inside the housing body.

[0041] In this case, it is further preferable that each of the cover members of the housing body is located inwardly of an axial end portion of the housing body.

[0042] This makes it possible to reduce the length of the shaft body, which is advantageous for making the faucet valve device more compact. Effect of the Invention

[0043] According to the present invention, the temperature can be adjusted according to the rotational position of the cylinder body, so that 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 operating part, it is suitable for realizing the motorization of the temperature adjustment.

[0044] In particular, according to the present invention, it is easy to position the shaft body support member at a suitable position toward the hot water side seal member and the water side seal member, and sufficient sealing performance of the hot water side seal member and the water side seal member can be ensured. Furthermore, since the protrusion or additional positioning piece does not act on the shaft body directly but indirectly via the shaft body support member, there is little risk of an undesirable increase in resistance when the shaft body rotates, and there is also no risk of the protrusion or additional positioning piece being worn away by the rotation of the shaft body.

[0046] Next, a faucet valve device according to an embodiment of the present invention will be described with reference to the attached drawings. The faucet valve device 100 of this embodiment is a faucet valve device suitable for achieving motorized temperature adjustment.

[0047] Fig. 1 is a schematic perspective view of a faucet valve device 100 according to one embodiment of the present invention, Fig. 2 is a schematic front view of the faucet valve device 100 of this embodiment, Fig. 3 is a schematic vertical cross-sectional perspective view of the faucet valve device 100 of this embodiment, and Fig. 4 is a schematic vertical cross-sectional view of the faucet valve device 100 of this embodiment. Also, Fig. 5 is an enlarged view of the cylinder body portion of Fig. 4, and Fig. 6 is a schematic perspective view showing the cylinder body 30 and shaft body 20 of this embodiment.

[0048] As shown in Figs. 1 to 6, a faucet valve device 100 of this embodiment includes a cylinder body 30 formed in a hollow cylindrical shape, and a housing body 10 that accommodates the cylinder body 30 in a rotatable manner.

[0049] [Cylinder body 30] The cylinder body 30 has, for example, an outer diameter of 15 mm, a wall thickness of 0.5 mm, and an axial length of 50 mm, and is made of stainless steel. When the cylinder body 30 is made of a resin material, it is preferable to make the wall thicker.

[0050] 5, a right end wall 31 made of resin is fitted to the right end side of the cylinder body 30. On the other hand, a left end wall 32 on the left end side of the cylinder body 30 is manufactured integrally with a peripheral wall 33 of the cylinder body 30 and is made of stainless steel.

[0051] A substantially rectangular water inlet hole 34 is provided in the right region of the peripheral wall 33 of the cylinder body 30. The water inlet hole 34 opens, for example, at a circumferential angle (angle measured around the axis) of 0° (which is used as the basis for the following explanation of angular positions) to 90°, and is formed in an area a certain distance from the right end of the cylinder body 30 in the axial direction.

[0052] A substantially rectangular molten metal inlet hole 35 is provided in the left region of the peripheral wall 33 of the cylinder body 30. The molten metal inlet hole 35 opens, for example, at a circumferential angle (angle measured around the axis) of 90° to 180° (i.e., opens at an angular position different from that of the water inlet hole 34) and is formed in an area a certain distance from the left end of the cylinder body 30 in the axial direction.

[0053] A hot and cold water outlet hole 36 is provided in the peripheral wall 33 of the cylinder body 30 in an approximately central region in the axial direction.

[0054] Moreover, the cylinder body 30 of this embodiment has a central pipe portion 37 extending from the right end wall 31 to approximately the center in the axial direction. A partition wall 38 extending radially outward from the central pipe portion 37 is provided at an axial position corresponding to the hot and cold water outlet hole 36 of the cylinder body 30 (see also FIG. 6).

[0055] [Shaft body 20] The shaft body 20 is inserted into the central tube portion 37 and is fixed to the right end wall 31 and the left end wall 32. This allows the shaft body 20 and the cylinder body 30 to rotate integrally. The shaft body 20 has a diameter of, for example, φ3 and is made of stainless steel.

[0056] [Housing body 10] The internal space of the housing body 10 that accommodates the cylinder body 30 is, for example, a cylindrical space, and a gap is provided between the cylinder body 30 and the peripheral wall 33. As shown in Fig. 4, the housing body 10 has a substantially cylindrical inner cylinder portion 10a and an outer cylinder portion 10b that surrounds the inner cylinder portion 10a, and the two are fixed to each other. The inner cylinder portion 10a is made of stainless steel, and the outer cylinder portion 10b is made of PPS resin.

[0057] 4 and 5 in particular, the left end of the internal space of the housing body 10 is defined by a left inner lid member 47. The left inner lid member 47 is a generally bottomed cylindrical member, and is fitted into the inner peripheral surface of the outer tubular portion 10b of the housing body 10 via an O-ring 47a. A through hole through which the shaft body 20 is inserted is provided in the center of the left inner lid member 47, and the through hole is sealed by an X-ring 47b while allowing the shaft body 20 to rotate.

[0058] Symmetrically, the right end of the internal space of the housing body 10 is defined by a right inner lid member 57. The right inner lid member 57 is a generally bottomed cylindrical member that is fitted into the inner peripheral surface of the outer tubular portion 10b of the housing body 10 via an O-ring 57a. A through hole through which the shaft body 20 is inserted is provided in the center of the right inner lid member 57, and the through hole is sealed by an X-ring 57b while allowing the shaft body 20 to rotate.

[0059] 4 and 5, the left inner lid member 47 is supported by the left inner lid auxiliary member 46. The left inner lid auxiliary member 46 is a generally disk-shaped member, and is fitted into the inner peripheral surface of the left inner lid member 47 via an O-ring 46a. The left inner lid auxiliary member 46 also has a through hole in the center through which the shaft body 20 is inserted, and the through hole is sealed by an X-ring 46b while allowing the shaft body 20 to rotate.

[0060] Symmetrically, the right inner lid member 57 is supported by the right inner lid auxiliary member 56. The right inner lid auxiliary member 56 is a roughly disk-shaped member, and is fitted into the inner peripheral surface of the right inner lid member 57 via an O-ring 56a. The right inner lid auxiliary member 56 also has a through hole in the center through which the shaft body 20 is inserted, and the through hole is sealed by an X-ring 56b while allowing the shaft body 20 to rotate.

[0061] 4 and 5, the left outer lid member 45 is disposed further to the left of the left inner lid member 47 and the left inner lid auxiliary member 46. The left outer lid member 45 is a generally bottomed cylindrical member, and is fitted into the inner circumferential surface (receiving portion) of the outer tubular portion 10b of the housing body 10. The left inner lid member 47 has a through hole in the center through which the shaft body 20 is inserted, and the through hole is sealed by a resin sliding bearing (bush) 45b while allowing the shaft body 20 to rotate.

[0062] A right outer lid member 55 is disposed symmetrically to the right of the right inner lid member 57 and the right lid auxiliary member 56. The right outer lid member 55 is a generally bottomed cylindrical member, and is fitted into the inner circumferential surface (receiving portion) of the outer tubular portion 10b of the housing body 10. A through hole through which the shaft body 20 is inserted is provided in the center of the right inner lid member 57, and the through hole is sealed by a resin sliding bearing (bush) 55b while allowing the shaft body 20 to rotate.

[0063] The housing body 10 is provided with a water supply passage, a hot water supply passage, and a hot and cold water outflow passage, which are in communication with the internal space thereof.

[0064] Specifically, the hot and cold water outlet path in this embodiment is provided by a hot and cold water outlet 15 that is integral with the housing body 10. The hot and cold water outlet 15 opens toward the top of the housing body 10 and is connected to a hot and cold water supply pipe (not shown) via, for example, an elbow connecting pipe (not shown).

[0065] In addition, the hot and cold water outlet 15 is provided at a size and position that allows all of the hot and cold water outlet holes 36 of the cylinder body 30 to communicate with each other regardless of the position or posture of the cylinder body 30 within the movable range.

[0066] On the other hand, the water supply passage of this embodiment is provided by the water supply pipe 11 formed in the outer cylinder 10b of the housing body 10 and the through hole 16h (see FIG. 7) of the water side seal member 16 (e.g., tile packing) housed or fitted in the corresponding notch of the inner cylinder 10a of the housing body 10. FIG. 7 is a schematic perspective view of the water side seal member 16 (tile packing). As shown in FIG. 7, the through hole 16h is a rectangular cross-sectional hole. At the time of shipment (before use), the abutting surface on the cylinder side of the water side seal member 16 (tile packing) is part of a cylindrical surface with a curvature radius of 8 mm, and the abutting surface on the outer cylinder 10b side is part of a cylindrical surface with a curvature radius of 12 mm, and the radial thickness between both sides is 4 mm, but after assembly, the thickness between both sides is compressed by about 5% due to the action of the protrusion 61 (or the protrusion 55p, the wedge member 62) described later.

[0067] The size and position (in the axial direction of the housing body 10) of the through hole 16h of the water side sealing member 16 are such that the through hole 16h can communicate with the entire water inlet hole 34 while being controlled to maximize the amount of communication between the through hole 16h and the water inlet hole 34 (see Figures 8 and 9 described below).

[0068] Similarly, the hot water supply passage in this embodiment is provided by the hot water supply pipe 13 formed in the outer cylinder 10b of the housing body 10 and the through hole 18h (see FIG. 7) of the hot water side seal member 18 (e.g., tile packing) housed or fitted in the corresponding notch of the inner cylinder 10a of the housing body 10. The through hole 18h also has a rectangular cross section (see FIG. 7). At the time of shipment (before use), the contact surface on the cylinder side of the hot water side seal member 18 (tile packing) is part of a cylindrical surface with a curvature radius of 8 mm, and the contact surface on the outer cylinder 10b side is part of a cylindrical surface with a curvature radius of 12 mm, and the radial thickness between both sides is 4 mm, but after assembly, the thickness between both sides is compressed by about 5% due to the action of the protrusion 61 (or protrusion 55p, wedge member 62) described later.

[0069] The size and position (in the axial direction of the housing body 10) of the through hole 18h of the hot water side seal member 18 are controlled so that the communication between the through hole 18h and the hot water inlet hole 35 is maximized, and the size and position are such that the through hole 18h can communicate with the entire hot water inlet hole 35 (see Figures 8 and 9 described below).

[0070] [Operation mechanism 40] 1 to 4, an operation mechanism 40 is provided on the left side (one axial side) of the cylinder body 30. The operation mechanism 40 has an operation unit 41 that is provided so as to be rotatable. In this embodiment, the operation unit 41 is a stepping motor that receives a control command from a control main body (not shown) and can be rotated by the control command.

[0071] In this embodiment, the shaft body 20 and the cylinder body 30 are adapted to have their rotational positions changed by rotating the operating portion 41 without changing their axial positions.

[0072] 4, the rotating shaft (output shaft) of the operating unit 41 is fixed in both the axial direction and the rotational direction to the bottom side of the rotating cylinder 42. The rotating cylinder 42 is disposed so that its bottom side is located on the left side, and is held within the housing cylinder 44 so as to be rotatable about its axis.

[0073] The left side of the housing cylinder 44 holds the main body of the operation portion 41. The right side of the housing cylinder 44 is connected (fitted) to the outer cylinder portion 10b of the housing body 10.

[0074] The right side (opposite the bottom) of the rotating cylinder 42 is open, and the sliding cylinder 43 is fitted therein so as to be slidable in the axial direction, and the rotating cylinder 42 and the sliding cylinder 43 are fixed in the rotation direction. For example, the sliding cylinder 43 has four convex parts that protrude in a cross shape in the axial cross section, and the rotating cylinder 42 has four concave parts that accommodate the four convex parts so as to be slidable in the axial direction. That is, each of the four convex parts is accommodated in each of the four concave parts, and when the rotating cylinder 42 rotates, the sliding cylinder 43 also rotates. (The sliding cylinder 43 is fixed in the rotation direction relative to the rotation shaft of the operating unit 41 as a connecting member, while being axially movable relative to the rotation shaft of the operating unit 41.)

[0075] The sliding cylinder 43 is fixed to the left end of the shaft body 20. As a result, when the sliding cylinder 43 rotates, the shaft body 20 and the cylinder body 30 also rotate in the same manner. On the other hand, since the sliding cylinder 43 is not fixed to the rotating cylinder 42 in the axial direction but is housed in the rotating cylinder 42, even if the shaft body 20 is subjected to an axial load, the rotating cylinder 42 is not subjected to the axial load.

[0076] In this embodiment, the operation unit 41 provides a rotation operation of up to 90°+α.

[0077] [Support mechanism 50] Meanwhile, a support mechanism 50 is provided on the right side (the other axial side) of the cylinder body 30. The support mechanism 50 rotatably supports the shaft body 20 and the cylinder body 30 without changing their axial positions.

[0078] Specifically, a housing cylinder 54 is provided substantially symmetrically to the housing cylinder 44. The housing cylinder 54 holds the right end of the shaft body 20 via a pair of retaining rings 58. As a result, the housing cylinder 54 and the shaft body 20 are rotatable relative to each other but are fixed in the axial direction.

[0079] Moreover, the housing cylinder 54 is connected (fitted) to the outer cylinder portion 10b of the housing body 10 at its left side.

[0080] [Both ends of shaft body 20] Due to the above-mentioned configuration, both ends of the shaft body 20 in this embodiment are located within an area that is blocked off so as not to communicate with the internal space of the housing body 10, and are open to the atmosphere (receive atmospheric pressure rather than water pressure).

[0081] Specifically, the left end of shaft body 20 is blocked off from communication with the internal space of housing body 10 by a plastic sliding bearing (bush) 45b and X-rings 46b, 47b, and the right end of shaft body 20 is blocked off from communication with the internal space of housing body 10 by a plastic sliding bearing (bush) 55b and X-rings 56b, 57b.

[0082] This significantly reduces the effect of water pressure in the internal space of the housing body 10 on the shaft body 20. This reduces the torque (force) required to rotate the shaft body 20 (and the cylinder body 30), i.e., reduces the torque required for the operating unit 41. It is even better if the diameter of the cut-off portion of the shaft body 20 is the same.

[0083] In addition, the housing body 10 has a left side outer cover member 45, a left side inner cover auxiliary member 46, and a left side inner cover member 47, as well as a right side outer cover member 55, a right side inner cover auxiliary member 56, and a right side inner cover member 57, in order to divide the internal space, and by removing these cover members 45-47, 55-57, it is easy to assemble or disassemble (e.g., for maintenance, etc.) the internal parts of the housing body 10.

[0084] Furthermore, in this embodiment, each of the left side inner cover member 47, left side inner cover auxiliary member 46, right side inner cover member 57 and right side inner cover auxiliary member 56 of the housing body 10 is positioned inward from the axial end of the housing body 10, thereby reducing the length of the shaft body 20.

[0085] [Water stop function] The faucet valve device 100 of this embodiment further includes a hot and cold water stop section that stops the flow of hot and cold water. Specifically, the hot and cold water stop section includes a water stop section 11s provided on the upstream side of the water supply passage, and a hot water stop section 13s provided on the upstream side of the hot water supply passage (see FIG. 2). This prevents hot or cold water from flowing back to the upstream side of the other.

[0086] [Sealing function] In addition, the faucet valve device 100 of this embodiment ensures sufficient sealing performance of the hot water side sealing member 18 and the water side sealing member 16 by positioning the left side outer cover member 45 and the right side outer cover member 55, which serve as shaft body support members, in suitable positions toward the hot water side sealing member 18 (tile gasket) and the water side sealing member 16 (tile gasket).

[0087] Specifically, the housing body 10 has a receiving portion 60 that receives the left outer cover member 45, and a protrusion 61 is provided in a part of the receiving portion 60 that abuts against the left outer cover member 45 (shaft body support member) that supports the shaft body 20 (adjusting the position of the left outer cover member 45 toward the hot water side sealing member 18 and the water side sealing member 16) so that the cylinder body 30 fixed (connected or integrated) to the shaft body 20 is biased toward the hot water side sealing member 18 and the water side sealing member 16.

[0088] Figure 10 is a front view showing the receiving portion 60 of the housing body 10 (which receives the right side outer cover member 55 as a cylinder body support member), Figure 11 is an enlarged view of portion XI of Figure 10, Figure 12 is a schematic oblique view showing the receiving portion 60 of the housing body 10, and Figure 13 is a schematic oblique view showing how the right side outer cover member 55 is fitted into the receiving portion 60 of the housing body 10.

[0089] As shown in Figs. 10 to 12, the receiving portion 60 is formed as a generally cylindrical space (inner diameter about 25 mm, axial length about 3 mm), and a protrusion 61 (in this embodiment, the lower exposed surface is a flat surface) in the form of a lowered ceiling surface with a height of about 0.3 mm and an axial length of about 2 mm is provided on the upper inner surface. The wear resistance of the protrusion 61 is lower than that of the resin sliding bearing (bush) 55b. On the other hand, the right outer cover member 55 received in the receiving portion 60 has a cylindrical outer peripheral edge contour with an outer diameter of about 25 mm and an axial length of about 3 mm, except for a pair of side protrusions 55s. The pair of side protrusions 55s are adapted to be fitted into a corresponding pair of side recesses 10r provided in the housing body 10.

[0090] More specifically, the pair of side projections 55s and the pair of side recesses 10r are fitted together when the upper end surface of the right outer lid member 55 is in contact with (pressed against) the projection 61 (over the entire axial length of the projection 61). However, the fitting state between the pair of side projections 55s and the pair of side recesses 10r may have some play in the up-down direction.

[0091] In addition, although detailed illustration is omitted, the housing body 10 is roughly symmetrical and has a receiving portion that receives the left side outer cover member 45, and a protrusion is provided on part of the receiving portion for adjusting the position of the left side outer cover member 45 toward the hot water side sealing member 18 and the cold water side sealing member 16.

[0092] By providing the pair of protrusions as described above, it is easy to urge (position) the left and right outer cover members 45, 55, which serve as shaft support members, toward the hot water side seal member 18 (tile packing) and the water side seal member 16 (tile packing) (to a suitable position), and to stably secure an appropriate seal margin. This ensures sufficient sealing performance of the hot water side seal member 18 and the water side seal member 16.

[0093] In addition, the pair of protrusions do not act directly on the shaft body 20, but indirectly through the left outer cover member 45 and the right outer cover member 55 that serve as shaft body support members, so there is little risk of an undesired increase in resistance during rotation of the shaft body 20, and there is also no risk of the protrusions being worn down by the rotation of the shaft body 20. Also, by ensuring these functions with the protrusions, it becomes possible to ensure a balance between the two by simply adjusting the size of the protrusions.

[0094] [Function of the faucet valve device 100] Next, the operation of the faucet valve device 100 of this embodiment will be described.

[0095] With the above-described configuration, the cylinder body 30 of this embodiment is adapted to change its rotational position by rotating the operating portion 41 without changing its axial position.

[0096] Temperature adjustment is realized by changing the amount of communication between the through hole 16h (water supply passage) of the water side seal member 16 and the water inlet hole 34, and the amount of communication between the through hole 18h (hot water supply passage) of the hot water side seal member 18 and the hot water inlet hole 35 according to the rotational position of the cylinder body 30. In this embodiment, the hot and cold water outlet hole 36 and the hot and cold water outlet passage are always maintained in a good state of communication. Figure 8 is a schematic diagram showing the state in which the water side seal member 16 and the hot water side seal member 18 of this embodiment abut against the cylinder body 30.

[0097] In this embodiment, by rotating the operating part 41, the ratio of the amount of communication between the through hole 16h (water supply passage) of the water side sealing member 16 and the water inlet hole 34 and the amount of communication between the through hole 18h (hot water supply passage) of the hot water side sealing member 18 and the hot water inlet hole 35 changes, thereby realizing temperature adjustment.

[0098] 9 is a schematic explanatory diagram of the position control of the cylinder body 30 in this embodiment. In this embodiment, the temperature is adjusted according to the rotational position of the cylinder body 30.

[0099] FIG. 9( a ) shows the positions of the water inlet hole 34 and the hot water inlet hole 35 in the peripheral wall 33 of the cylinder body 30 .

[0100] 9(b) shows a schematic diagram of a state in which the communication between the through hole 16h (water supply passage) of the water-side seal member 16 and the water inlet hole 34 is at a maximum, and the communication between the through hole 18h (hot water supply passage) of the hot water-side seal member 18 and the hot water inlet hole 35 is blocked. At this time, the hot and cold water mixture output through the hot and cold water outlet hole 36 and the hot and cold water outlet passage is 100% water and 0% hot water.

[0101] Figure 9(c) shows a schematic state in which the shaft body 20 and cylinder body 30 have changed their rotational positions by rotating the operating part 41 from the state shown in Figure 9(b), so that the communication between the through hole 16h (water supply passage) of the water-side seal member 16 and the water inlet hole 34 is 50%, and the communication between the through hole 18h (hot water supply passage) of the hot water-side seal member 18 and the hot water inlet hole 35 is also 50%. At this time, the hot and cold water mixture output through the hot and cold water outlet hole 36 and the hot and cold water outlet passage is 50% water and 50% hot water.

[0102] Fig. 9(d) shows a schematic diagram of a state in which the shaft body 20 and cylinder body 30 have changed their rotational positions by further rotating the operating part 41 from the state shown in Fig. 9(c), blocking communication between the through hole 16h (water supply passage) of the water-side seal member 16 and the water inlet hole 34, and maximizing communication between the through hole 18h (hot water supply passage) of the hot water-side seal member 18 and the hot water inlet hole 35. At this time, the hot and cold water mixture output through the hot and cold water outlet hole 36 and the hot and cold water outlet passage is 0% water and 100% hot water.

[0103] [Basic effect] As described above, according to the faucet valve device 100 of this embodiment, temperature adjustment is achieved according to the rotational position of the cylinder body 30, so that a compact faucet valve design can be realized.

[0104] Furthermore, according to the faucet valve device 100 of this embodiment, there is no hindrance to motorizing the operating portion 41, and therefore it is suitable for realizing motorized temperature adjustment.

[0105] Moreover, according to the faucet valve device 100 of this embodiment, a shaft body 20 is provided which axially penetrates the cylinder body 30 and is fixed (connected) to the cylinder body 30. This makes it possible to realize control for changing the position of the cylinder body 30 with a relatively simple configuration for controlling the position of the shaft body 20.

[0106] According to the faucet valve device 100 of this embodiment, the housing body 10 has a receiving portion 60 that receives the left outer cover member 45 and the right outer cover member 55 (shaft body support member), and a protrusion 61 is provided in a part of the receiving portion 60 that abuts against the left outer cover member 45 and the right outer cover member 55 (shaft body support member) that support the shaft body 20 (adjusting the position of the left outer cover member 45 and the right outer cover member 55 toward the water side seal member 16 and the hot water side seal member 18) so that the cylinder body 30 fixed (connected or integrated) to the shaft body 20 is biased toward the hot water side seal member 18 and the hot water side seal member 16. This makes it easy to stably secure an appropriate seal margin by biasing the left outer cover member 45 and the right outer cover member 55 (shaft body support member) toward the water side seal member 16 and the hot water side seal member 18 (positioning them at a suitable position), and sufficient sealing performance of the water side seal member 16 and the hot water side seal member 18 can be guaranteed. Furthermore, since the protrusion 61 does not act directly on the shaft body 20, but indirectly acts on the shaft body 20 via the left side outer cover member 45 and the right side outer cover member 55 (as well as the plastic sliding bearing (bush) 45b and the plastic sliding bearing (bush) 55b), there is little risk of an undesirable increase in resistance when the shaft body 20 rotates, and there is also no risk of the protrusion being worn down by the rotation of the shaft body 20.

[0107] Furthermore, according to the faucet valve device 100 of this embodiment, the left outer cover member 45 and the right outer cover member 55 support the shaft body 20 via the resin sliding bearing (bush) 45b and the resin sliding bearing (bush) 55b, respectively. This makes it possible to effectively maintain the centering function of the shaft body 20, and to firmly press the cylinder body 30 against the water side seal member 16 and the hot water side seal member 18.

[0108] Furthermore, according to the faucet valve device 100 of this embodiment, the left outer cover member 45 and the right outer cover member 55 are provided on both sides of the cylinder body 30. This allows the entire cylinder body 30 to be firmly pressed against the water side seal member 16 and the hot water side seal member 18.

[0109] Furthermore, according to the faucet valve device 100 of this embodiment, a sliding cylinder 43 is provided as a connecting member that is fixed (connected) to the left end of the shaft body 20 and fixed in the rotational direction relative to the operating part 41, and the sliding cylinder 43 is movable in the axial direction relative to the operating part 41. This ensures that the rotational operation of the operating part 41 can be transmitted as a rotational force of the shaft body 20, while the operation of the operating part 41 is not hindered by a force that may act in the axial direction of the shaft body 20.

[0110] Furthermore, according to the faucet valve device 100 of this embodiment, a support mechanism 50 is provided that restricts the axial movement of the right end of the shaft body 20, but does not restrict the rotation of the right end of the shaft body 20. As a result, while restricting the axial movement of the right end of the shaft body 20, the rotation of the shaft body 20, and therefore the operation of the operating part 41, is prevented from being hindered.

[0111] Furthermore, the faucet valve device 100 of this embodiment is provided with a hot and cold water stopper that stops the flow of hot and cold water. This ensures a reliable water stopper function even when the water is not completely stopped by simply adjusting the flow rate to the minimum using the flow rate adjustment function (when the sealing function is insufficient in the cutoff control state).

[0112] In particular, according to the faucet valve device 100 of this embodiment, the hot and cold water stop section is composed of a water stop section 11s provided upstream of the water supply passage and a hot and cold water stop section 13s provided upstream of the hot water supply passage, thereby preventing hot or cold water from flowing back to the upstream side of the other.

[0113] [Effect of being open to the atmosphere] Moreover, according to the faucet valve device 100 of this embodiment, the shaft body 20 penetrates the cylinder body 30 in the axial direction, and both ends of the shaft body 20 are in an area that does not communicate with the internal space of the housing body 10 and are open to the atmosphere. This significantly reduces the effect of water pressure in the internal space of the housing body 10 on the shaft body 20. This reduces the torque (force) required to rotate the shaft body 20, which is very convenient for achieving electrification.

[0114] In particular, according to the faucet valve device 100 of this embodiment, the left end of the shaft body 20 is blocked from communicating with the internal space of the housing body 10 by the resin sliding bearing (bush) 45b and the X-rings 46b and 47b, and the right end of the shaft body 20 is blocked from communicating with the internal space of the housing body 10 by the resin sliding bearing (bush) 55b and the X-rings 56b and 57b. This extremely effectively suppresses the effect of the water pressure in the internal space of the housing body 10 on the shaft body 20. In addition, the diameters of the parts at the left and right ends of the shaft body 20 that are blocked from communicating with the internal space of the housing body 10 are equal, and are configured to cancel out the acting water pressure.

[0115] Furthermore, according to the faucet valve device 100 of this embodiment, a left outer lid member 45, a left inner lid auxiliary member 46, and a left inner lid member 47, as well as a right outer lid member 55, a right inner lid auxiliary member 56, and a right inner lid member 57 are provided to partition the internal space of the housing body 10. This makes it easy to assemble or disassemble (for example, for maintenance) the internal parts of the housing body 10 by removing these lid members 45-47, 55-57.

[0116] Furthermore, according to the faucet valve device 100 of this embodiment, the left inner lid member 47, the left inner lid auxiliary member 46, the right inner lid member 57, and the right inner lid auxiliary member 56 of the housing body 10 are each located inward from the axial end of the housing body 10. This reduces the length of the shaft body 20, which is convenient for making the faucet valve device 100 compact.

[0117] [Other embodiments] FIG. 14 is a schematic perspective view showing how a right outer cover member 55 and a wedge member 62 (additional positioning protrusion) are fitted into a receiving portion 60 of a housing body 10 of another embodiment.

[0118] In the embodiment shown in Figure 14, instead of providing a protrusion 61 on a part of the receiving portion 60, a wedge member 62 (additional positioning piece) is inserted into a part between the area (outer peripheral edge area) of the right outer cover member 55 (same for the left outer cover member 45) that is received in the receiving portion 60 and the receiving portion 60, and abuts against the right outer cover member 55 (same for the left outer cover member 45) and the receiving portion 60 (adjusting the position of the right outer cover member 55 (same for the left outer cover member 45) toward the water side sealing member 16 and the hot water side sealing member 18) so that the cylinder body 30 fixed to the shaft body 20 is urged toward the water side sealing member 16 and the hot water side sealing member 18 when the area is received in the receiving portion 60.

[0119] Even in this embodiment, it is easy to stably secure an appropriate seal by biasing (positioning at an appropriate position) the left and right outer cover members 45, 55, which serve as shaft support members, toward the hot water side seal member 18 (tile packing) and the water side seal member 16 (tile packing). This ensures sufficient sealing performance of the hot water side seal member 18 and the water side seal member 16.

[0120] Furthermore, since the pair of wedge members 62 (additional positioning pieces) do not act directly on the shaft body 20, but indirectly via the left outer cover member 45 and the right outer cover member 55 which serve as shaft body support members, there is little risk of an undesired increase in resistance when the shaft body 20 rotates, and there is also no risk of the protrusions being worn down by the rotation of the shaft body 20. Furthermore, by ensuring these functions with the wedge members 62 (additional positioning pieces), it becomes possible to ensure a balance between the two by simply adjusting the size of the wedge members 62 (additional positioning pieces).

[0121] The wedge member 62 may be made of a rigid material or an elastic material. In the latter case, the left outer cover member 45 and the right outer cover member 55 (shaft body support member) can be elastically (gently) pressed against the water side seal member 16 and the hot water side seal member 18. However, it is preferable that the wear resistance of the wedge member 62 is lower than the wear resistance of the resin sliding bearings (bush) 45b, 55b.

[0122] Furthermore, instead of the wedge member 62 (instead of the wedge shape), an additional positioning piece having another shape capable of substituting the function of the protrusion 61 may be inserted.

[0123] [Further another embodiment] FIG. 15 is a schematic perspective view showing a right outer cover member 55' according to still another embodiment.

[0124] In the embodiment shown in Figure 15, instead of providing a protrusion 61 on a part of the receiving portion 60, a protrusion 55p is provided on a part of the area (outer peripheral area) of the right-side outer cover member 55' (same for the left-side outer cover member) that is received in the receiving portion 60, which abuts against the receiving portion 60 so that the cylinder body 30 fixed to the shaft body 20 is forced toward the water side sealing member 16 and the hot water side sealing member 18 when the area is received in the receiving portion 60 (adjusting the position of the right-side outer cover member 55' (same for the left-side outer cover member) toward the water side sealing member 16 and the hot water side sealing member 18).

[0125] 10 to 12, the receiving portion 60 is formed as a generally cylindrical space (outer diameter 25 mm, axial length 3 mm), but no protrusion 61 is provided. On the other hand, the right outer cover member 55' (similar to the left outer cover member) received in the receiving portion 60 has a columnar outer peripheral edge contour with an outer diameter of 25 mm and an axial length of 3 mm, except for the protrusion 55p and a pair of side protrusions 55s. The protrusion 55p is formed as a raised cylindrical surface with a maximum outer diameter of 0.3 mm, a width of the maximum outer diameter region of 1 mm, and an axial length of 2 mm. The pair of side protrusions 55s are adapted to fit into a corresponding pair of side recesses 10r provided in the housing body 10.

[0126] More specifically, the pair of side projections 55s and the pair of side recesses 10r are fitted together when the projection 55p (over the entire axial length) of the right outer lid member 55' (similar to the left outer lid member) is in contact with (pressed against) the receiving portion 60. However, there may be some play in the up-down direction in the fitting state between the pair of side projections 55s and the pair of side recesses 10r.

[0127] Even in this embodiment, it is easy to stably secure an appropriate seal by biasing (positioning at an appropriate position) the left and right outer cover members 55' as shaft support members toward the hot water side seal member 18 (tile packing) and the water side seal member 16 (tile packing). This ensures sufficient sealing performance of the hot water side seal member 18 and the water side seal member 16.

[0128] In addition, the pair of protrusions 55p do not act directly on the shaft body 20, but indirectly through the left and right outer cover members 55' as shaft body support members, so there is little risk of an undesired increase in resistance when the shaft body 20 rotates, and there is also no risk of the protrusions being worn down by the rotation of the shaft body 20. Also, by ensuring these functions with the protrusions, the balance between the two can be achieved by simply adjusting the size of the protrusions. [Explanation of symbols]
