JP-A-2004-360873 (FIG. 1)

  In the conventional water faucet, it was necessary to replace the valve device 94 itself when stopping the use of a specific water discharge form according to the use environment of the water faucet. For example, in a water tap installed in a shower facility at a beach, both the shower and the spout are used during the off-season, such as when employees use the water spout from the spout for bucket cleaning. On the other hand, during the summer bathing season, we would like to let the beach users use only showers. In such a case, when the conventional shower / water outlet switching valve device as described above is installed in advance, during the sea bathing season, the switching valve device in the faucet is removed and only the shower discharge hole is provided. It is necessary to install a water shut-off valve device that is established and can discharge water only from the shower.

  On the contrary, there is a case where it is desired to disable only the shower for a certain period of time and allow water discharge only from the water outlet. Alternatively, in a faucet capable of switching between purified water and tap water, there is a case where it is desired to stop water discharge of either purified water or tap water for a certain period. In some cases, it is desirable to stop all water discharge within a certain period. In these cases as well, it is necessary to replace the valve device corresponding to each water discharge restriction in the same manner as described above. In addition, although it is not necessary to stop water discharge, it is necessary to replace with another valve device in which the opening area of the discharge hole is reduced in order to suppress the maximum water discharge amount in a specific water discharge mode.

  For this reason, if it sees from the user side who changes a use aspect regularly, it is necessary to arrange the several valve apparatus according to the use aspect of a water tap, and it was not economical. Moreover, since it was necessary to replace | exchange the valve apparatus itself from the supplier's side of the faucet, the replacement work was complicated. In addition, a plurality of valve devices according to the usage form must be stocked, which has been a factor in increasing the stock cost. Further, from the viewpoint of the manufacturer of the valve device, a plurality of valve device molds or the like corresponding to the use mode are required, which increases the manufacturing cost of the valve device.

  The present invention solves the problems of the above-described conventional valve device of a water faucet, and performs cost reduction as a valve device capable of stopping water according to the use form while sharing the main body of the valve device. An object of the present invention is to provide a valve device for a faucet that can be used.

  In order to solve the above problems, means taken by the present invention will be described below. The valve device for a faucet of the present invention has a cylindrical housing having a discharge hole provided in a peripheral wall, and a communication hole that is rotatably disposed in the housing and can be aligned with the discharge hole. A spindle provided with an inlet that is connected to the flow path to the communication hole on one end side; and by operating a faucet handle attached to the other end side of the spindle, the discharge hole and the communication hole are A valve device of a water faucet that is communicated and discharges water from a water discharge portion, and is detachably engaged with a contact portion provided on one of the housing side or the spindle side and the other side. And a guide member provided with a contacted part that restricts the rotation of the spindle by contacting the contact part. The contacted part of the guide member has at least a full opening of the discharge hole. Not to be before A valve device faucet, characterized in that it is shaped to restrict the rotation range of the spindle (claim 1).

  A communication hole is provided in a spindle that is rotatable with respect to the housing, and the spindle is rotated and moved to a position that aligns with the discharge hole on the housing side. This is a valve device that discharges hot water or the like flowing in from the discharge hole and discharges water from a water discharge portion such as a shower or a water discharge port connected to the tip of the discharge hole. The rotation range of the spindle is such that the contact portion provided on one of the housing side or the spindle side and the contacted portion provided on the guide member detachably engaged with the other are contacted. Regulated by In the present invention, the guide member is detachably provided, and the rotation range of the spindle can be changed only by replacing the guide member with a different length of the abutted portion. “Water faucet” includes all faucets such as a faucet with a shower, a faucet with a water purifier, or a single faucet.

  The shapes of the “contact portion” and “contacted portion” are not particularly limited as long as they can be contacted so that the rotation of the spindle is restricted. For example, the abutting portion is a projection formed on the housing side, and the abutted portion is a projection provided on the guide member, so that the guide member with a different position of the projection of the guide member is replaced with a conventional guide. The rotation range of the spindle can be made different from that when the member is attached. Further, the contact portion is an end portion of an arc-shaped groove provided on the housing side, and the contacted portion may be an arc-shaped protrusion that can be accommodated in the groove. ). An arc-shaped protrusion may be provided on the housing side, and an end provided in the arc-shaped groove on the guide member may be used as a contacted portion of the guide member.

  The guide member is not limited to be detachably attached to the spindle side but may be attached to the housing side. Further, the abutted portion is shaped so as to restrict the rotation range of the spindle so that the discharge hole is not fully opened. For example, even when the spindle is most rotated, only a part of the discharge hole is opened. It may be used to reduce the maximum water discharge amount, or may be used to stop water discharge by restricting the rotation of the spindle so that no discharge hole is opened.

  The housing is provided with a plurality of discharge holes, and the contacted portion of the guide member is configured to regulate the rotation range of the spindle so that one of the plurality of discharge holes cannot be opened. (Claim 2).

  For example, when this valve device is used for a water faucet with a water purifier, if water purification is no longer necessary after the water faucet is installed, it is only necessary to replace it with a guide member that disables opening of the water outlet. The water can be prevented from being discharged very easily.

  Further, for example, the housing is provided with a discharge hole communicating with the water discharge port and a discharge hole communicating with the shower device, and the contacted portion of the guide member has one discharge hole of these discharge holes. It is good also as what is formed in the shape which controls the rotation range of a spindle so that opening is impossible (Claim 3).

  In such a valve device, water discharge from the water discharge port or the shower device can be simply prevented as necessary.

  In the present invention, as described above, the contacted portion of the detachable guide member is formed in a shape that regulates the rotation range of the spindle so that the discharge hole of the housing is not fully opened. Since the rotation range of the spindle can be changed simply by replacing the guide member with a different length or the like, it is possible to very easily prevent specific water discharge or limit the maximum flow rate. .

  Next, an embodiment of a valve device for a faucet of the present invention will be described in detail with reference to the drawings. As shown in FIG. 1, the valve device 1 of the present invention is not shown in the figure, but is attached to a hot and cold water mixing faucet that discharges water from the water outlet and the shower device, and switches between the water outlet and the water discharged from the shower device. It is a valve device. The valve device 1 includes a housing 10, a spindle 40 that is rotatably mounted in the housing 10, and a guide member 70 that is engaged with and attached to the spindle 40. Further, a switching handle (not shown) is attached to the spindle 40 in order to switch the water discharge from the water outlet and the shower device.

  As shown in FIGS. 1 and 2, the housing 10 is formed in a cylindrical shape, and mixed water in which hot water and water are mixed at an appropriate temperature in a mixing valve device (not shown) flows into one end side thereof. An opening 12 connected to the flow path is opened. Moreover, the opening part 14 by which the front-end | tip part 46 of the spindle 40 is rotatably hold | maintained is opened at the other end side.

  A total of four discharge holes 16 and 18 are provided in the peripheral wall of the housing 10, which are juxtaposed in the axial direction of the housing 10. The discharge holes 16 and the discharge holes 18 are provided at different positions in the circumferential direction of the housing 10. Further, on the outer peripheral surface of the housing 10, the seal member 2 is mounted between the discharge holes 16 and 18, outside the discharge hole 16, and outside the discharge hole 18, and around the discharge holes 16 and 18. The housing 10 and the water passage (not shown) of the faucet body in which the housing 10 is accommodated are watertight.

  In addition, a first sleeve 22 and a second sleeve 24 are mounted inside the housing 10 so as to be connected to the spindle 40 in the axial direction of the spindle 40. The first sleeve 22 is formed so as to cover the inside of the discharge hole 18, and a water passage hole 23 having the same shape as the discharge hole 18 is opened at a position corresponding to the discharge hole 18, and is attached to the opening 12 side. Has been. The second sleeve 24 is formed in a shape covering the inside of the discharge hole 16, and a water passage hole (not shown) having the same shape as the discharge hole 18 is opened at a position corresponding to the discharge hole 16. It is mounted on the part 14 side. In addition, seal members 3 are mounted around the water passage holes so that the inner peripheral surface of the housing 10 and the sleeves 22 and 24 are watertight.

  A locking portion 26 is provided at the end of the second sleeve 24 on the opening 12 side. The locking portion 26 is locked to a locking portion 20 formed on the inner peripheral surface of the housing 10, so that the housing The second sleeve 24 is positioned in the axial direction and the circumferential direction. The first sleeve 22 is also positioned by the positioned second sleeve 24. The first sleeve 22 is prevented from coming off by a flange 42 provided at a base end portion of a spindle 40 described later via a ring 27.

  A small-diameter portion 28 protrudes from the opening 14 side of the housing 10. An engagement semi-cylindrical portion 72 of a guide member 70 is attached to the outer peripheral surface of the small diameter portion 28 as will be described later. Further, a groove (not shown) in which the engaging portion 73 of the engaging semi-cylindrical portion 72 is engaged is formed on the outer peripheral surface of the small diameter portion 28 along the axial direction of the small diameter portion 28. It is formed in the position which substantially opposes on both sides. At the intermediate position between the water outlet side and the shower device side, that is, the position of the switching handle where neither water is discharged, the engaging portion 73 is locked in the groove, and the switching handle is rotated at this position. In this case, the water stop operation position of the switching handle can be clearly sensed by giving resistance to the operation feeling of the switching handle.

  Further, as shown in FIGS. 1 and 3, the upper end surface of the step portion 33 formed on the back end side of the small-diameter portion 28 has an angle range of about 244 degrees around the axis of the housing 10. A groove 34 formed in an arc shape is formed, and a contacted portion 74 of a guide member 70 described later is movably accommodated in the groove 34. Then, the abutted portion 74 of the guide member 70 that rotates with the rotation of the spindle 40 is abutted by the abutting portions 35 at both ends of the groove 34, whereby the rotation of the spindle 40 is restricted. It will be.

  Next, the spindle 40 will be described. The spindle 40 is provided with a proximal end portion 44 that is substantially accommodated in the housing 10 and a distal end portion 46 with which the switching handle meshes in the circumferential direction. As described above, the flange 42 is provided around the inflow port 45 at the end of the base end portion 44. The base end portion 44 is accommodated in the sleeves 22 and 24, and a total of four communication holes 48 and 50 arranged in parallel in the axial direction of the base end portion 44 are opened on the peripheral wall. The discharge holes 16 and 18 are formed at the same interval and in the same shape as the discharge holes 16 and 18, and overlap the discharge holes 16 or 18 when the spindle 40 is rotated. 18 is formed in a shape and arrangement that can be opened. The communication holes 48 and 50 are provided at different positions in the circumferential direction of the base end portion 44 of the spindle 40.

  In this example, when the spindle 40 is properly positioned and attached to the housing 10, when viewed from the front end side of the spindle 40, the spindle 40 is turned from the neutral position on the water discharge port side and the shower device side in the turning operation of the spindle 40. When the spindle 40 is rotated about 90 degrees around, the discharge hole 18 and the communication hole 50 are perfectly aligned so that the maximum amount of water discharge can be obtained from the water discharge port. Then, when the spindle 40 is rotated about 90 degrees clockwise from the neutral position, the discharge hole 16 and the communication hole 48 are perfectly aligned so that the maximum amount of water discharge can be obtained from the shower device. It has been.

  A seal member 4 is mounted on the outer peripheral surface on the proximal end side of the distal end portion 46, together with the seal member 3 described above, for watertightness between the inner peripheral surface of the housing 10 and the outer peripheral surface of the distal end portion 46 in the distal end direction of the spindle 40. . A serration 52 is engraved along the axial direction of the outer peripheral surface of the tip 46 closer to the tip than the portion where the seal member 4 is mounted. A groove 56 in which the E-ring 54 is mounted is provided in the middle of the serration 52, and the E-ring 54 allows the guide member 70 engaged with the serration 52 to be removed from the spindle 40 as will be described later. Stopped.

  The guide member 70 is attached with its abutted portion 74 being inserted into the groove 34 of the housing 10. As shown in FIG. 2, the guide member 70 is formed in a substantially cylindrical overall shape. A serration 78 that meshes with the serration 52 of the spindle 40 described above is formed on the inner peripheral surface of the cylindrical base portion 76. On the lower side of the inner peripheral surface of the base portion 76 in which the serrations 78 are engraved, a ridge 80 protrudes along the axis of the base portion 76. The protrusion 80 is fitted in a groove 47 formed along the axial center below the outer peripheral surface of the tip end portion 46 of the spindle 40, whereby the guide member 70 is positioned in the circumferential direction of the spindle 40. Made.

  Further, the engagement semi-cylindrical portion 72 described above protrudes from a substantially lower half portion on one end side of the base portion 76, and the bulging engagement portions are provided at both ends of the engagement semi-cylindrical portion 72. 73 is formed. The engaging semi-cylindrical part 72 is connected to the base part 76 only at the center thereof, and both end sides of the engaging semi-cylindrical part 72 are formed to be elastically flexible. Therefore, when the guide member 70 is engaged with the groove 47 of the housing 10 and the guide member 70 is rotated as the spindle 40 is rotated, a feeling of resistance can be given.

  In addition, an arc-shaped contacted portion 74 projects from the upper half portion of the base portion 76. As shown in FIG. 3, the abutted portion 74 is formed in the range of about 154 degrees around the axis of the guide member 70. In the guide member 70 that is properly positioned with respect to the spindle 40 by the fitting of the protrusion 80 and the groove 47, the contacted portion 74 is viewed from the front end direction of the spindle 40 and the groove 34 of the housing 10. It is provided so as to be located within an angle range of about 32 degrees to the left and about 122 degrees to the right from the center position. Therefore, as shown in FIG. 3, when the guide member 70 is attached with the guide member 70 appropriately positioned with respect to the spindle 40, the contacted portion 74 has the right end of the contacted portion 74 at the right end of the groove 34. It will be in the state contact | abutted by the contact part 35, and cannot be rotated at all clockwise. Therefore, by mounting the guide member 70, it becomes impossible to align the communication hole 48 with the discharge hole 16, and therefore, water discharge from the shower device can be prevented. On the other hand, in the counterclockwise direction, the spindle 40 can be rotated counterclockwise until the left end of the contacted portion 74 contacts the contact portion 35 at the left end of the groove 34. When rotated, the communication hole 50 and the discharge hole 18 are perfectly aligned, and the maximum amount of water discharge can be obtained from the water discharge port.

  Thus, in the valve device 1, one end of the abutted portion 74 is extended, and the water discharged from the water outlet and the shower device is originally simply replaced with the guide member 70 that is detachable from the valve device 1 body. For the valve device 1 that is possible, water discharge from the water discharge port can be performed as usual, while water discharge from the shower device cannot be performed.

  The present invention is not limited to the embodiment described above, and various modifications can be made within the scope of the gist of the present invention. For example, contrary to the above-described embodiment, when it is possible to discharge water only from the shower device and do not want to discharge water from the water outlet, the protrusions 80 and the grooves 47 are appropriately positioned with respect to the spindle 40. In the guide member 82 in this state, the contacted portion 74 is extended to an angle range of about 122 degrees to the left and about 32 degrees to the right from the center position of the groove 34 when viewed from the front end side of the spindle 40. The member 82 may be prepared and attached. When the guide member 82 is attached, the valve device 1 is configured such that the communication hole 48 is aligned with the discharge hole 16 communicating with the shower device when the spindle 40 is rotated clockwise as shown in FIGS. Although the water discharge from the shower device is possible, contrary to FIGS. 4 to 6, even if the spindle 40 is rotated counterclockwise, the discharge hole 18 and the communication hole 50 are not communicated and the water discharged from the water discharge port is discharged. You can make it impossible to do. In addition, it is not limited to using the valve device that can switch the water discharge form from the water outlet and the shower device, for example, for the valve device that can switch between purified water and tap water, Conversely, it can also be used to prevent any tap water from being discharged.

  Moreover, it can be used not only to completely disable any water discharge form but also to limit the maximum water discharge amount of any water discharge form. 7 to 9 show a valve device 1 that prevents water from being discharged from the shower device and slightly suppresses the maximum water discharge amount at the water outlet. In this valve device 1, in the guide member 84 in a state of being properly positioned with respect to the spindle 40 by fitting of the protrusion 80 and the groove 47, it is about 36 to the left from the center position of the groove 34 when viewed from the front end side of the spindle 40. On the right side, a guide member 84 having a contacted portion 74 extended to an angle range of about 122 degrees is prepared and attached. Therefore, as shown in FIGS. 7 to 9, when the spindle 40 is fully rotated counterclockwise, the communication hole 50 is partially aligned with the discharge hole 18 communicating with the water discharge port, and water is discharged from the water discharge port. The maximum water discharge amount can be suppressed, and water can be saved.

  Further, as shown in FIGS. 10 to 12, when a guide member 86 having a contacted portion 74 formed in the same angle range (a range of about 244 degrees) as the groove 34 of the housing 10 is used, The contact portion 74 cannot be moved left and right by the contact portions 35 at both ends in the groove 34, and water cannot be discharged from the water discharge port or the shower device. Even in the case of a single faucet, if a guide member having a contacted portion formed in the same angle range as the groove of the housing is used, the contacted portion is caused by the contact portions at both ends in the groove. It cannot move to right and left, and it can also be made not to be able to discharge water from a water outlet or a shower apparatus.

  In the above-described embodiment, the end portion in the groove 34 on the housing 10 side is referred to as a “contact portion”, and the arc-shaped protrusions such as the guide member 70 are referred to as “contact portions”. Not limited. For example, as the contact portion, a “projection” or the like that can restrict the movement of the contacted portion 74 is formed at an appropriate position of the stepped portion 33 of the housing 10. Anything that can regulate movement is acceptable. Further, the abutment portion may be provided on either the housing side or the spindle side, and the guide member may be detachably engaged with a member on the opposite side of the member provided with the abutment portion. It may be attached to any member.
