  In the single lever mixer tap as shown in Patent Document 1, there is a convenient part that the adjustment of the water discharge flow rate and the water discharge temperature can be operated with a single lever handle. Therefore, every time water discharge is started, it is necessary to adjust the water discharge flow rate every time. In addition, when switching the water discharge, the water discharge temperature setting may be changed unexpectedly. For this reason, it is difficult to reproduce the same water discharge flow rate and the same water discharge temperature setting as in the previous water discharge state when performing the water stop operation once in the water discharge state and then performing the water discharge operation again. There is still room for improvement in the desire to discharge water at the same water discharge temperature setting.

  Moreover, although the water discharging apparatus of patent document 2 is equipped with the structure which has arrange | positioned the operation part for performing switching of the water discharge and adjustment of water discharge flow volume collectively, it is for adjusting the water discharge temperature. No operation unit is provided. For this reason, when it is going to install the operation part for water discharge temperature adjustment separately in the water discharging apparatus of patent document 2, the problem that an installation area will increase by the part of this operation part will arise.

  The present invention has been made in view of such a problem, and can suppress a change in the setting of the water discharge flow rate and the water discharge temperature associated with the switching operation of the discharge water, and can effectively reduce a narrow installation area. It aims at providing the valve apparatus which can be utilized.

  The valve device according to the present invention is a valve device that switches between water discharge and water stop by a pressing operation, and adjusts the water discharge flow rate and water discharge temperature by a rotation operation, and has a rotating part that rotates by the rotation operation. A temperature control valve unit that changes the water discharge temperature by changing the mixing ratio of water and hot water according to the amount of rotation of the unit, and a moving unit that moves in the direction of the rotation axis of the rotating unit by a rotating operation. A flow control valve unit that changes the water discharge flow rate according to the position, and an opening / closing operation unit that advances and retracts in the direction of the rotation axis by receiving a pressing operation to move the moving unit to a water discharge position or a water stop position, and switches between water discharge and water stop And by changing the position of the moving part at the water discharge position by receiving a rotation operation, a flow adjustment operation part for adjusting the water discharge flow rate, and changing the amount of rotation of the rotating part by receiving the rotation operation, Temperature control operation to adjust water discharge temperature When, those having a.

  According to the valve device having such a configuration, the adjustment of the water discharge temperature by the temperature adjustment valve unit and the adjustment of the water discharge flow rate by the flow adjustment valve unit are performed by rotating the temperature adjustment operation unit and the flow adjustment operation unit around the central axis. Further, the switching of the discharge water by the flow control valve unit can be operated by a pressing operation that advances and retreats on the central axis of the opening / closing operation unit. That is, the operation direction of the temperature adjustment operation unit and the flow adjustment operation unit and the operation direction of the opening and closing operation unit can be made different from each other, and the operation for switching the discharge water is the adjustment of the discharge water temperature and the adjustment of the discharge water flow rate. Therefore, it is possible to discharge water with the same water discharge flow rate and water discharge temperature setting as the previous time. In addition, since the opening / closing operation unit, the flow adjustment operation unit, and the temperature adjustment operation unit are provided at coaxial positions, the opening / closing operation unit, the flow adjustment operation unit, and the temperature adjustment operation unit in the valve device are provided in one place. Can be installed intensively. Thereby, each operation part is independent, and installation with a small installation area becomes possible compared with the structure which installs each operation part separately.

  In the valve device according to another aspect of the present invention, the temperature adjustment operation unit is disposed on an outer peripheral side of the flow adjustment operation unit.

  According to the valve device having such a configuration, the operation portion of the temperature adjustment operation portion has a larger radial dimension than the operation portion of the flow adjustment operation portion, and thus it is possible to finely adjust the water discharge temperature. The water discharge temperature can be adjusted with high accuracy.

  In the valve device according to another aspect of the present invention, the opening / closing operation unit and the flow adjustment operation unit are configured by an integral operation member that performs an advance / retreat operation by a pressing operation and a rotation operation by a rotation operation, and The adjustment operation unit has a substantially cylindrical recess for storing the operation member. When the moving unit is in the water stop state at the water stop position, the operation member is stored in the recess. In the water discharge state in which the pressing surface that receives the pressing operation and the opening end surface where the opening of the concave portion faces are located on substantially the same plane and the moving portion is in the water discharging position, the pressing surface protrudes from the opening end surface. Is.

  According to the valve device having such a configuration, in the water stop state, the upper end surface of the operation member is substantially flush with the upper end surface of the temperature adjustment operation unit. It is possible to suppress an unintentional flow adjustment operation (rotation operation) of the operation member by hitting the operation member. Thereby, it can suppress that the water discharge flow volume from the last time of water discharge changes at the time of the next water discharge by operating a flow control operation part unintentionally in a water stop state. In addition, when switching from the water stop state to the water discharge state, the operation member protrudes from the upper end surface of the temperature adjustment operation unit, so the user adjusts the water discharge flow rate by holding the protruding operation member and rotating it. Therefore, good operability can be obtained for adjusting the water discharge flow rate. Further, since the opening / closing operation unit and the flow adjustment operation unit are configured by an integral operation member, the number of components of the operation unit of the valve device can be reduced, and the configuration of the operation unit can be simplified.

  In the valve device according to another aspect of the present invention, the flow control valve unit includes an outflow channel forming body in which an opening communicating with the flow channel of the temperature control valve unit is formed, and the moving unit includes: It has a sliding valve body that changes the communication area of the opening and changes the water discharge flow rate by moving forward and backward in the direction of the rotation axis in the outflow channel forming body.

  According to the valve device having such a configuration, the flow control valve section changes the opening area of the opening provided in the flow passage formed by the outflow passage forming body by the sliding valve body, thereby It is possible to adjust the flow rate of discharged water and to switch the discharged water.

  In the valve device according to another aspect of the present invention, the temperature control valve unit has a fixed valve body in which a water supply channel to which water is supplied and a hot water supply channel to which hot water is supplied is formed, The rotating part includes a communication channel provided on the fixed valve body and communicating with at least one of the water supply channel and the hot water supply channel, and a through hole formed in the central shaft portion. A valve body is provided, and the outflow channel forming body is disposed in the through-hole so as to communicate the opening with the communication channel.

  According to the valve device having such a configuration, the temperature adjustment valve portion that adjusts the mixing ratio of water and hot water and the flow adjustment valve portion that adjusts the discharge water flow rate are partitioned by the outflow passage. The rotation of the rotating valve body can be prevented from being transmitted to the sliding valve body, and the mixing ratio of water and hot water, that is, the water discharge temperature is changed by switching the water discharge and adjusting the water discharge flow rate. This can be suppressed.

  ADVANTAGE OF THE INVENTION According to this invention, the change of the setting of the discharged water flow volume and discharged water temperature accompanying the switching operation of discharged water can be suppressed, and a narrow installation area can be utilized effectively.

The operation cylinder portion 137 is formed to have substantially the same diameter as the clutch ring member 36 and the like. The operation member 37 is in a state where the operation tube portion 137 is supported by the clutch ring member 36 fitted on the sliding member 33, that is, in a state where the lower surface of the operation tube portion 137 is in contact with the upper surface of the clutch ring member 36. Provided.

  At the lower end of the operation member 37, there is formed a locking piece 37c cut out by two slits along the vertical direction adjacent to each other in the circumferential direction. The locking pieces 37 c are provided at two positions facing each other in the radial direction in the circumferential direction of the operation member 37. On the inner peripheral side of the distal end portion (lower end edge portion) of the locking piece 37c, a locking claw portion 37d is formed along the edge of the locking piece 37c. Thus, the locking piece 37c having the locking claw portion 37d is a shape portion for the operating member 37 to be locked to the cam groove forming member 34 as described later.

  The operation member 37 receives the connection of the flow adjustment dial button 8 at the upper part thereof. The operating member 37 has an engaging groove portion 37g in the upper outer peripheral surface portion as a portion that engages with the flow adjustment dial button 8. The engagement groove portion 37g has a plurality of vertical grooves 37h along the vertical direction provided so as to form irregularities in the circumferential direction on the outer peripheral surface portion of the operation member 37.

  As shown in FIG. 16, the flow control dial button 8 is an operation main body portion 8 a that follows a substantially disk-shaped outer shape having a large plate thickness, and a portion that is provided inside the operation main body portion 8 a and is connected to the operation member 37. And a certain cylindrical connecting portion 8b. 16A is a perspective view from the lower surface side of the flow control dial button 8, and FIG. 16B is a longitudinal sectional perspective view of the flow control dial button 8.

  The operation main body portion 8a has a substantially inverted petri dish shape with the lower surface opened, and has a peripheral wall portion 8c forming a substantially cylindrical surface and a flat plate-like top surface portion 8d formed on the upper side of the peripheral wall portion 8c. . An upper surface 8f of the flow control dial button 8 which is an upper surface of the top surface portion 8d is formed along a horizontal plane (a plane perpendicular to the central axis direction). The connecting portion 8b is a cylindrical portion that is provided so as to protrude downward from the central portion of the lower surface of the top surface portion 8d of the operation main body portion 8a and has an opening on the lower side.

  The flow adjustment dial button 8 has the connecting portion 8 b as an engaging portion with respect to the operation member 37 and is fitted on the upper portion of the operation member 37. Therefore, an engagement groove 8g that engages with the engagement groove 37g of the operation member 37 is formed on the inner peripheral surface portion of the connecting portion 8b. The engaging groove portion 8g has a plurality of vertical grooves 8h along the vertical direction provided so as to form unevenness corresponding to the uneven shape of the engaging groove portion 37g on the inner peripheral surface portion of the connecting portion 8b.

  In this way, the flow control dial button 8 and the operation member 37 are mutually non-rotatable about the central axis direction in the spline fitting mode with the engaging groove 8g and the engaging groove 37g as the fitting direction. They are engaged and fitted and fixed together. As a result, the operation member 37 moves and rotates integrally with the flow tone dial button 8 that receives a pressing operation along the central axis direction and a rotational operation with the central axis O1 as the rotation axis.

  The flow control dial button 8 has an outer diameter slightly smaller than the inner diameter of the recess 9c of the temperature control dial 9, is arranged concentrically with respect to the temperature control dial 9, and is provided in a form that fits into the recess 9c ( (See FIG. 4). Therefore, the flow control dial button 8 is provided so as to leave a slight gap between the outer peripheral surface 8k and the inner peripheral surface 9k of the recess 9c.

  According to the configuration as described above, the sliding member 33 in the state of being biased upward by the coil spring 32 in accordance with the vertical movement of the flow control dial button 8 to be pressed is provided with the operation member 37 and the clutch ring. It moves up and down via the member 36 and the rotor 35. The vertical movement of the sliding member 33 is accompanied by the vertical movement of the sliding valve body 22 on the lower end side of the support rod portion 23 whose upper end portion is supported by the support surface portion 33 h of the sliding member 33. That is, the sliding member 33 and the sliding valve body 22 move up and down integrally. In this way, the flow control dial button 8 that moves up and down integrally under the urging force of the coil spring 32, the operation member 37, the clutch ring member 36, the rotor 35, the sliding member 33, the support rod portion 23, and the sliding Regarding the operation of the structure composed of the valve body 22 (hereinafter referred to as “sliding valve up-and-down movement structure”), the cam groove forming member 34 acts so that the flow control dial button 8 as the opening / closing mechanism section 30 as described above operates. Every time the pressing operation is performed, an operation of alternately moving the sliding valve body 22 to the water discharge position and the water stop position is performed.

  The cam groove forming member 34 will be described. The cam groove forming member 34 is a substantially cylindrical member whose both upper and lower sides are open, and the cylindrical portion 31 c of the knock cam base member 31 with the lower end portion fitted and fixed to the base portion 31 a of the knock cam base member 31. Are concentrically enclosed. The cam groove forming member 34 is provided at such a height that its upper end surface is slightly lower than the upper end surface of the cylindrical portion 31c.

  As shown in FIGS. 17A, 17B, and 17C, three engagement pieces 34a are provided at the lower end portion of the substantially cylindrical cam groove forming member 34 at equal intervals in the circumferential direction of the opening edge. A rectangular engagement hole 34b whose longitudinal direction is the circumferential direction of the cam groove forming member 34 is formed in each engagement piece 34a. On the other hand, as shown in FIGS. 11A and 11B, on the outer peripheral surface of the base 31a of the knock cam base member 31, there are three engagement protrusions 31k corresponding to the shape and dimensions of the engagement hole 34b. It is provided corresponding to the arrangement of the holes 34b. With such a configuration, for example, when the knock cam base member 31 is pushed into the cam groove forming member 34 from below, the engagement protrusion 34k is fitted into the engagement hole 34b with the elastic deformation. Thus, the cam groove forming member 34 and the knock cam base member 31 are engaged and fixed to each other. In the outer peripheral surface of the base 31a of the knock cam base member 31, a portion where the engagement protrusion 31k is provided is formed with a recess 31m having a depth substantially the same as the thickness of the engagement piece 34a of the cam groove forming member 34. The outer peripheral surface 34c of the cam groove forming member 34 and the outer peripheral surface 31n of the base portion 31a are configured to be substantially continuous with the engaging piece 34a fitted to the engaging protrusion 31k. .

  At the upper end of the cam groove forming member 34, a flange-shaped flange 34d in which the outer diameter of the cam groove forming member 34 is increased is provided. Further, on the outer peripheral surface 34c of the cam groove forming member 34, a ridge-shaped protrusion 34e is provided along the vertical direction. The protrusion 34e is formed so that the surface on the outer peripheral side is continuous with the flange 34d, and extends from the flange 34d to the vicinity of the lower end of the cam groove forming member 34. The protrusions 34e are provided at two positions that are opposed to each other in the radial direction in the circumferential direction of the cam groove forming member 34, that is, at two positions that are approximately 180 ° apart in the circumferential direction. The protrusion 34e is a part for defining a relative rotation range of the operation member 37 with respect to the cam groove forming member 34, as will be described later.

  The inner diameter of the cam groove forming member 34 is slightly larger than the outer diameter of the rotor 35 or the like so that the rotor 35 or the like enters the cam groove forming member 34. It is slightly smaller than the inner diameter of the operation member 37 so that the forming member 34 enters the operation member 37. That is, with respect to the above-described sliding valve vertical movement structure, the cam groove forming member 34 is located in an annular space between the rotor 35 and the operation member 37 in a sectional view in the central axis direction, It moves up and down relatively with respect to the vertically moving structure of the sliding valve. In other words, the upper part of the cam groove forming member 34 is positioned in a cylindrical space between the rotor 35 and the operation member 37 below the partition wall 37a of the operation member 37, and the sliding valve is moved up and down. As the structure moves up and down, the amount of insertion into the cylindrical space is changed.

  Here, the operation member 37 is externally fitted to the cam groove forming member 34 from above. When the operation member 37 is externally fitted to the cam groove forming member 34, the locking claw portion 37 d formed on the inner side of the locking piece 37 c at the lower end portion of the operation member 37 is the flange portion at the upper end of the cam groove forming member 34. Interfering with 34d. For this reason, in the process of external fitting of the operation member 37 to the cam groove forming member 34, the locking piece 37c is pushed to the outer peripheral side due to the locking claw portion 37d interfering with the flange portion 34d and elastically deformed, When the locking claw portion 37d gets over the flange portion 34d, it returns to its original shape and is locked to the flange portion 34d. Therefore, in a state where the operation member 37 is fitted on the cam groove forming member 34, the locking claw portion 37d is positioned below the protruding portion toward the outer peripheral side of the flange portion 34d.

  A plurality of cam grooves 134 for engaging with the rotor 35 are formed on the inner peripheral surface portion of the cam groove forming member 34. The cam groove 134 is a longitudinal groove of a streak along the vertical direction, and is provided in a substantially upper third portion of the cam groove forming member 34 in the vertical direction except for the engagement piece 34a. In the present embodiment, twelve cam grooves 134 are provided at equal intervals in the circumferential direction of the cam groove forming member 34.

  The lower side of the cam groove 134 is opened, and a cam protrusion 234 having a lower end surface portion 234a is formed between the cam grooves 134 adjacent to each other in the circumferential direction of the cam groove forming member 34. That is, the cam groove 134 has a lower open portion between the lower end surface portions 234a of the cam protrusion 234 in the circumferential direction. As described above, in the cam groove forming member 34 provided with the twelve cam grooves 134, there are twelve cam protrusions 234. Accordingly, the cam groove forming member 34 has a cam groove forming member 34 having twelve cam protrusions 234 within the range of the vertical length of the cam groove 134 with respect to the inner peripheral surface 34f of the cam groove forming member 34. The groove 134 is protruded with a gap in the width.

  The cam groove 134 and the cam protrusion 234 become a portion that engages with a rotation locking protrusion 135 that protrudes on the outer peripheral side of the rotor 35 located inside the cam groove forming member 34. The rotor 35 engages the rotation locking protrusion 135 with the cam groove 134 or the cam protrusion 234. The state where the rotor 35 engages the rotation locking projection 135 with the cam groove 134 corresponds to the state where the sliding valve body 22 is located at the water discharge position, that is, the water discharge state of the valve device 5. The state in which the rotor 35 engages the rotation locking protrusion 135 with the cam protrusion 234 corresponds to the state in which the sliding valve body 22 is located at the water stop position, that is, the water stop state of the valve device 5. . Each of these states is alternately switched every time a pressing operation of pressing the flow adjustment dial button 8 by a predetermined amount.

  The engagement structure between the cam groove forming member 34 and the rotor 35 will be described in detail. As shown in FIG. 13 and FIG. 18, the rotation locking protrusion 135 of the rotor 35 is viewed from the protruding direction along the radial direction of the rotor 35 (in a sectional view perpendicular to the protruding direction). It has a substantially trapezoidal shape in which both sides in the circumferential direction are sides along the vertical direction parallel to each other, and has a guide slope 135a on the upper side. The guide slope 135a is a slope that descends from the lower side to the upper side of the rotation direction of the rotor 35 (see arrow B1 in FIG. 18). In FIG. 18, for convenience, the lower peripheral wall portion of the rotor 35 is not shown.

  The cam groove 134 of the cam groove forming member 34 with respect to the rotation locking projection 135 allows the rotation locking projection 135 to move in the vertical direction in a state where the rotation locking projection 135 is fitted in the cam groove 134. It is formed in such a width. That is, the width of the rotation locking projection 135 (the dimension between the planes parallel to each other) is such that the vertical movement is allowed in a state where the rotation locking projection 135 is fitted in the cam groove 134. The dimensions are approximately the same as the width of 134.

  The cam protrusion 234 locks the rotation locking protrusion 135 at the lower end surface portion 234a. The lower end surface portion 234a of the cam ridge 234 is a lower side (hereinafter simply referred to as “lower side”) of the upper side piece 234b positioned on the upper side (hereinafter simply referred to as “upper side”) of the rotor 35 in the rotational direction. And a lower-side piece 234c located at a lower side, and a substantially inverted “V” -shaped recess is formed as a planar shape along the inner peripheral surface 34f of the cam groove forming member 34. Eggplant.

  The upper-side piece 234b has a side surface 234e on the upper side of the cam ridge 234 and a locking slope 234f that forms an acute angle with the side surface 234e as a plane that forms a planar shape along the inner peripheral surface 34f. The lower side piece 234c is a plane along the inner peripheral surface 34f, and is a surface along the vertical direction, forming an inner side 234g with the locking slope 234f, and the inner side 234g. It has a guide slope 234 h that forms an acute angle, and a lower side surface 234 j of the cam ridge 234. According to such upper-side piece 234b and lower-side piece 234c, a substantially inverted “V” -shaped recess is formed along a right-angled triangle having the lower side as a right side.

  The locking slope 234f and the guide slope 234h that form the lower end surface portion 234a of the cam ridge 234 are both surfaces along the guide slope 135a of the rotation locking projection 135, and correspond to the inclination angle of the guide slope 135a. The tilt angle is substantially the same as the guide slope 135a. That is, the locking slope 234f and the guide slope 234h are both slopes facing downward so as to follow the guide slope 135a, and are substantially parallel to each other.

  According to such a shape of the lower end surface portion 234a of the cam protrusion 234, the rotation locking projection 135 can be fitted to the concave portion of the lower end surface portion 234a from below. Further, the guide slope 234h of the lower side piece 234c is a slope that widens the lower end of the cam groove 134 toward the upper side.

  According to the engagement structure between the cam groove forming member 34 and the rotor 35 as described above, the rotation locking projection 135 with respect to the cam groove forming member 34 in accordance with the rotational operation of the rotor 35 causes A state like this is obtained. As shown in FIG. 19, in a state where the rotation locking projection 135 is in the engagement position with respect to the cam groove 134, the rotation locking projection 135 can move upward along the cam groove 134. 35 is allowed to move upward relative to the cam groove forming member 34. Thereby, the sliding valve up-and-down moving structure is positioned upward by the biasing force of the coil spring 32, and the valve device 5 is in the water discharging state when the sliding valve body 22 is positioned in the water discharging position.

  On the other hand, as shown in FIG. 18, in the state where the rotation locking projection 135 is in the engagement position with respect to the cam projection 234, the rotation locking projection 135 is fitted into the recess of the lower end surface portion 234a of the cam projection 234. Therefore, the upward movement of the rotor 35 relative to the cam groove forming member 34 is restricted. Thereby, the sliding valve vertical movement structure is positioned below against the urging force of the coil spring 32, and the sliding valve body 22 is positioned at the water stop position, so that the valve device 5 enters a water stop state. Such an engagement operation of the rotation locking projections 135 with respect to the cam grooves 134 and the cam protrusions 234 is performed simultaneously on the four rotation locking projections 135 of the rotor 35.

  With regard to the engaging operation of the rotation locking projection 135 with the cam groove 134 and the cam protrusion 234, the opening / closing mechanism 30 is configured such that the rotor 35 rotates by a predetermined amount by the pressing operation of the flow dial button 8. Yes. The rotating operation of the rotor 35 accompanying the pressing operation of the flow control dial button 8 is obtained by the meshing action of the upper clutch tooth surface 36c of the clutch ring member 36 and the lower clutch tooth surface 35c of the rotor 35. Specifically, it is as follows.

  In a normal state where the flow control dial button 8 is not subjected to a pressing operation, the lower clutch tooth surface 35c and the upper clutch tooth surface 36c are engaged with each other in a shifted state (with play). The relative positions of the rotor 35 and the clutch ring member 36 in the rotational direction are defined (see FIGS. 18 and 19). Such a positional relationship between the rotor 35 and the clutch ring member 36 is defined as an engagement position of the rotation locking projection 135 with respect to the cam groove 134 and the cam protrusion 234 for the rotor 35. Is defined by an external fitting position where the relative rotation with respect to the sliding member 33 is impossible.

  In this way, the lower clutch tooth surface 35c and the upper clutch tooth surface 36c are disengaged and engaged with each other, and the flow control dial button 8 is pushed down by the pressing operation so that the upper and lower clutch tooth surfaces 35c and 36c are engaged with each other without a gap. By the action, an automatic turning action of the rotor 35 is obtained. Here, since the position of the clutch ring member 36 in the rotation direction is fixed by the engaging action with respect to the sliding member 33, only the rotor 35 rotates.

  Further, the positional relationship between the rotor 35 and the clutch ring member 36 in a state where the upper and lower clutch tooth surfaces 35c and 36c are displaced from each other is the same as that of the rotor 35 due to the meshing action of the upper and lower clutch tooth surfaces 35c and 36c. The rotation direction is defined to be a predetermined direction. The rotation direction of the rotor 35 is a direction (see arrow B1 in FIG. 18) toward the side where the guide inclined surface 135a of the rotation locking projection 135 is raised.

  The amount of rotation of the rotor 35 accompanying one pressing operation of the flow adjustment dial button 8 corresponds to one of the protrusions 35d and 36d of the upper and lower clutch tooth surfaces 35c and 36c. In the case of the present embodiment, the upper and lower clutch tooth surfaces 35c and 36c have 24 protrusions 35d and 36d that are continuous, respectively, so that the amount of rotation of the rotor 35 associated with one press operation of the flow control dial button 8 Is a rotation amount (angle) obtained by dividing one round (360 °) into 24 equal parts. The amount of rotation of the rotor 35 corresponds to twelve cam grooves 134 and cam protrusions 234 that are alternately present in the circumferential direction in the cam groove forming member 34.

  Next, the flow adjustment mechanism 40 will be described. The flow adjustment mechanism 40 is a mechanism for transmitting the rotation operation of the flow adjustment dial button 8 as the vertical movement of the sliding valve body 22. That is, when the flow adjustment dial button 8 is rotated by the flow adjustment mechanism 40, the sliding valve body 22 at the water discharge position moves in the vertical direction and flows out of the communication flow path 13a of the rotary valve body 13. The communication area of the opening 21a between the inside of the flow path forming body 21 changes, and the discharged water flow rate changes. As the flow adjustment mechanism unit 40, the operation member 37 and the clutch ring member 36 constituting the opening / closing mechanism unit 30 function.

  The flow adjustment mechanism 40 basically functions in the water discharge state of the valve device 5. In the water discharge state of the valve device 5, the operation member 37 has a specified height position. The height position of the operation member 37 in this water discharge state is determined by the engagement of the engagement piece 37c provided at the lower end of the operation member 37 in the configuration in which the sliding valve vertical movement structure is biased upward by the coil spring 32. The claw portion 37d is defined by being locked to the flange portion 34d at the upper end of the cam groove forming member 34. That is, an operation of receiving an upward biasing force from the coil spring 32 through the sliding member 33, the rotor 35, and the clutch ring member 36 when the locking claw portion 37 d is hooked from the lower side with respect to the flange portion 34 d. The upward movement of the member 37 is restricted.

  In this way, the operation member 37 and the clutch ring member 36 whose height positions are defined in the water discharge state can rotate the flow control dial button 8 by the shape of the mating surface between the operation tube portion 137 and the clutch ring member 36. At the same time, the operation member 37 is configured to automatically move the clutch ring member 36 up and down by rotating around the central axis O1. The vertical movement of the clutch ring member 36 is the vertical movement of the sliding valve body 22 via the rotor 35, the sliding member 33, and the support rod portion 23.

  Specifically, the mating surface shape of the operation tube portion 137 and the clutch ring member 36 is as follows. As shown in FIG. 14A, a lower inclined surface portion 36e that gradually changes its height in the circumferential direction is formed on the upper surface side of the annular or short cylindrical clutch ring member 36. The lower inclined surface portion 36e forms an inclined surface along a spiral shape. The lower inclined surface portion 36e is provided in units of 180 ° in the circumferential direction of the clutch ring member 36 with respect to a predetermined height position (position in the central axis direction) of the clutch ring member 36, that is, in a manner divided into two in the circumferential direction. It has been. Therefore, the boundary part of the two lower inclined surface parts 36e becomes a discontinuous shape by the level | step difference of the lowest position of one lower inclined surface part 36e, and the highest position of the other lower inclined surface part 36e.

  On the other hand, as shown in FIG. 15D, the lower surface of the operation tube portion 137 of the operation member 37 is inclined in the same manner as the lower inclined surface portion 36e as a portion that fits the lower inclined surface portion 36e of the clutch ring member 36. An upper inclined surface portion 137e that forms a surface is formed. That is, the upper inclined surface portion 137e is a portion that forms a slope along a spiral that gradually changes the height in the circumferential direction of the operation tube portion 137, and is provided in units of 180 ° in the circumferential direction of the operation tube portion 137. Yes. Thus, the upper surface portion of the clutch ring member 36 having the lower inclined surface portion 36e and the lower surface portion of the operation cylinder portion 137 having the upper inclined surface portion 137e are formed at the boundary between the two lower inclined surface portions 36e or the upper inclined surface portion 137e. In a state where the stepped surfaces 36f and 137f are brought into contact with each other as a circumferential mating surface and are engaged with each other (see FIG. 19), they are engaged with each other with almost no gap so that a substantially continuous cylindrical portion is formed by the peripheral wall portions. The tooth surface shape is symmetrical in the vertical direction.

  Further, the lower inclined surface portion 36e of the clutch ring member 36 has a tooth surface shape in which a large number of mountain-shaped protrusions 36g forming a ridge line along the radial direction of the clutch ring member 36 are continuous along the circumferential direction, and a saw tooth along the circumference. Shape (zigzag shape). On the other hand, the upper inclined surface portion 137e on the operation member 37 side is provided with two locking protrusions 137g having the same shape as the mountain-shaped protrusion 36g of the lower inclined surface portion 36e. In each upper inclined surface portion 137e, the locking projections 137g are provided at two locations, the vicinity of the highest position and the substantially central position in the circumferential direction. Therefore, a total of four locking protrusions 137 g in the operation tube portion 137 are located at four positions that are substantially equally spaced in the circumferential direction of the operation tube portion 137.

  Each locking projection 137g of the operation tube portion 137 is fitted into a valley portion between adjacent projections 36g with respect to the tooth surface shape of the lower inclined surface portion 36e (see FIG. 19). Then, as the operation member 37 is rotated relative to the clutch ring member 36 by the rotation operation of the flow adjustment dial button 8, each locking protrusion 137g moves on the lower inclined surface portion 36e while getting over the protrusion 36g. When the rotation operation is released, the locking projection 137g is in a state of being fitted to any valley. The four locking projections 137g have the same positional relationship with respect to the valleys in the tooth surface shape of the lower inclined surface part 36e, and are simultaneously fitted to the corresponding valleys.

  Such a fitting shape between the tooth surface shape of the lower inclined surface portion 36e of the clutch ring member 36 and the locking projection 137g of the operation member 37 gives a knocking feeling to a person who rotates the flow control dial button 8. That is, with respect to the rotation operation of the flow control dial button 8, every time the locking projection 137g gets over the projection 36g on the clutch ring member 36 side with the rotation of the operation member 37, in other words, the trough where the locking projection 137g fits. A resistance is generated each time the is changed, and an intermittent resistance feeling is obtained as an operation feeling. In addition, as a shape part for causing a knocking feeling in this way, a tooth surface shape having a sawtooth shape along the circumference is formed on the operation cylinder part 137 side, the structure opposite to the upper and lower sides of this embodiment, A structure in which a locking projection is formed on the clutch ring member 36 side may be employed.

  According to the flow adjustment mechanism 40 as described above, in the water discharge state in which the height position of the operation member 37 is defined as described above, the operation member 37 rotates as the flow adjustment dial button 8 rotates. The contact range in the circumferential direction of the inclined surface portion 137e and the lower inclined surface portion 36e changes, and the relative positions of the operation member 37 and the clutch ring member 36 in the vertical direction change due to the inclination of both inclined surface portions. That is, since the height position of the operation member 37 is constant in the water discharge state, the vertical position of the clutch ring member 36 is changed in accordance with the rotation operation of the flow adjustment dial button 8. The change in the vertical position of the clutch ring member 36 changes the height position of the sliding valve body 22 at the water discharge position via the rotor 35, the sliding member 33, and the support rod portion 23. Thereby, the communication area of the opening 21a and the communication flow path 13a changes, and the discharged water flow rate changes.

  In such a flow adjustment mechanism 40, the stepped surfaces 36f and 137f formed at the boundary between the clutch ring member 36 and the operating member 37 are closest to each other, that is, at the boundary between the two lower inclined surface portions 36e or the upper inclined surface portion 137e. Is the state where the sliding valve body 22 is located at the uppermost position with respect to the adjustment of the discharged water flow rate, and corresponds to the state where the discharged water flow rate is maximum (see FIG. 19). From this state, as the operating member 37 rotates, the clutch ring member 36 is pushed down (see FIG. 20), the sliding valve body 22 moves downward, and the water discharge flow rate decreases. Therefore, with respect to the rotational operation direction of the flow adjustment dial button 8 that rotates integrally with the operation member 37, the direction in which the height of the lower inclined surface portion 36e gradually increases (the clockwise rotation direction) corresponds to the direction in which the discharged water flow rate decreases. And the opposite direction (left rotation direction) respond | corresponds to the direction which increases water discharge flow volume.

  With respect to the turning operation of the operation member 37 with respect to the clutch ring member 36 in the flow adjustment mechanism 40, the operation member 37 provided in a form externally fitted to the cam groove forming member 34 is the outer periphery of the cam groove forming member 34. By being locked with respect to the surface portion, rotation of a predetermined amount or more is restricted. Specifically, the locking claw portion 37d of the locking piece 37c formed at the lower end portion of the operation member 37 comes into contact with the protrusion 34e formed on the outer peripheral surface portion of the cam groove forming member 34 from the side end surface side. By stopping, the rotation of the operation member 37 is restricted.

  Both the locking claw portion 37d and the protrusion 34e are provided at two positions separated by about 180 ° in the circumferential direction, and the rotation range of the operation member 37 is defined at about 180 °. As a result, the rotation of the operation member 37 in the direction of decreasing the discharged water flow rate exceeds the state where the clutch ring member 36 and the operation member 37 are farthest from each other, and the gap between the two inclined surface portions in the circumferential direction. Beyond the step, the operation member 37 and the clutch ring member 36 are suddenly engaged (closest to each other), and the water discharge flow rate is restricted from rapidly changing (increasing).

  The moving range of the vertical movement of the sliding valve body 22 by the flow adjustment mechanism 40 in the water discharge state of the valve device 5 as described above is the height of the step surfaces 36f and 137f with respect to the upper and lower inclined surfaces (dimensions in the vertical direction). Is almost the same. The vertical movement range of the sliding valve body 22 by the flow adjustment mechanism 40 is the vertical movement range between the water discharge position and the water stop position of the sliding valve body 22 by the opening / closing mechanism section 30 as described above. Small enough compared to

  As described above, in the valve device 5 of the present embodiment, the flow adjustment dial button 8 functions as an opening / closing operation unit operated by a pressing operation by the opening / closing mechanism unit 30 and is rotated by the flow adjustment mechanism unit 40. It functions as a flow control unit operated by operation. In other words, in this embodiment, the opening / closing operation unit for switching the water discharge and the flow adjustment operation unit for adjusting the water discharge flow rate are integrated operations for performing a forward / backward movement operation by a pressing operation and a rotation operation by a rotation operation. The flow control dial button 8 is a member.

  A temperature adjustment dial 9 as a temperature adjustment operation unit that constitutes the operation unit 6 of the valve device 5 together with the flow adjustment dial button 8 has a substantially cylindrical recess 9 c that houses the flow adjustment dial button 8. That is, the temperature control dial 9 is provided in a form in which the flow control dial button 8 having a substantially short cylindrical outer shape is housed in a substantially cylindrical recess 9c whose upper surface side is the open side.

  In the operation unit 6 having such a configuration, the temperature adjustment dial 9 as the temperature adjustment operation unit is disposed on the outer peripheral side of the flow adjustment dial button 8 as the flow adjustment operation unit. Specifically, the flow control dial button 8 has a substantially short cylindrical outer shape, and the temperature control dial 9 is a substantially short portion as a portion that forms a substantially cylindrical recess 9c that houses the flow control dial button 8. It has the operation main-body part 9a along a cylindrical external shape. In the temperature adjustment dial 9, an operation main body 9 a that is an operation portion that is gripped when the temperature adjustment dial 9 is rotated is disposed on the outer peripheral side of the flow adjustment dial button 8. In other words, the flow adjustment dial button 8 and the operation main body portion 9a of the temperature adjustment dial 9 are concentrically arranged around the central axis O1 with the operation main body portion 9a positioned on the outer peripheral side with respect to the flow adjustment dial button 8. The outer peripheral surface 8k of the flow control dial button 8 and the inner peripheral surface 9k of the recess 9c are opposed to each other with a predetermined gap.

  Further, in the operation portion 6 of the valve device 5, the flow adjustment dial button 8 is housed in the recess 9 c of the temperature adjustment dial 9 in the water stop state where the sliding valve body 22 is in the water stop position. The upper surface 8f serving as a pressing surface for receiving the pressing operation 8 and the upper surface 9f serving as an opening end surface facing the opening of the recess 9c are positioned on substantially the same plane. And the upper surface 8f of the flow control dial button 8 protrudes from the upper surface 9f in the water discharging state in which the sliding valve body 22 is in the water discharging position.

  Thus, the flow adjustment dial button 8 that appears and disappears from the concave portion 9c of the temperature adjustment dial 9 every time a pressing operation of pushing a predetermined amount is operated in a state of protruding from the concave portion 9c, that is, in the water discharge state of the valve device 5. Therefore, the outer peripheral surface 8k of the flow adjustment dial button 8 exposed in a state of protruding from the recess 9c becomes an operation surface that is gripped when the flow adjustment dial button 8 is rotated, that is, a rotation operation surface for adjusting the water discharge flow rate. Further, regarding the pressing operation of the flow tone dial button 8, the upper surface of the flow tone dial button 8 which is a surface perpendicular to the central axis direction which is the direction (pressing direction) of the flow tone dial button 8 by the pressing operation. 8f becomes an operation surface to be pressed, that is, a pressing operation surface for switching the discharge water. As for the temperature control dial 9, the outer peripheral surface portion of the peripheral wall portion 9d provided with the plurality of protrusions 9j is an operation surface that is gripped when the temperature control dial 9 is rotated, that is, a rotation operation surface for adjusting the water discharge temperature. Become.

  In the operation unit 6 of such a valve device 5, the flow adjustment dial button 8 forms a substantially flush surface with the temperature adjustment dial 9 in the water stop state, and when switching from the water stop state to the water discharge state. , It protrudes from the concave portion 9c of the temperature control dial 9 with a single touch, and can be rotated. The temperature adjustment dial 9 is rotated independently of the flow adjustment dial button 8 regardless of the operation state of the flow adjustment dial button 8.

  Operation | movement of the valve apparatus 5 of this embodiment provided with the above structures is demonstrated.

  First, the adjustment of the water discharge temperature by rotating the temperature control dial 9 (see arrow X2 in FIG. 1) will be described with reference to FIG. The state shown in FIG. 21A is a state in which the temperature adjustment dial 9 is rotated to the maximum in the counterclockwise direction (counterclockwise) when the valve device 5 is viewed from above, and the discharged water is discharged from the valve device 5. The water is discharged. In this state, as shown in FIG. 21A, the fan-shaped communication flow path 13 a of the rotary valve body 13 that rotates integrally with the temperature adjustment dial 9 passes through the water inflow hole 11 a of the bottom member 11. Is communicated only with the water supply flow path 12a of the fixed valve body 12 into which the water flows. That is, in the state shown in FIG. 21A, the hot water supply flow path 12b is closed by the rotary valve body 13, and the water flowing in from the water inflow hole 11a remains as it is (without being mixed with hot water). The water flows into the outflow channel forming body 21 from the water supply channel 12a through the opening 21a, flows downward, and flows out from the outflow hole 11c of the bottom member 11. The water flowing out from the outflow hole 11c is supplied to the spout 3 through a water supply pipe (not shown) disposed between the valve device 5 and the spout 3 as described above, and is discharged from the water outlet 3a of the spout 3.

  On the other hand, the state shown in FIG. 21B is a state in which the temperature adjustment dial 9 is rotated to the maximum in the clockwise direction (clockwise) when the valve device 5 is viewed from above, and the water discharged from the valve device 5 is discharged. As hot water is discharged. In such a state, as shown in FIG. 21 (b), the fan-shaped communication flow path 13 a of the rotary valve body 13 that rotates integrally with the temperature control dial 9 passes through the hot water inlet hole 11 b of the bottom member 11. Is communicated only with the hot water supply flow path 12b of the fixed valve body 12 into which the gas flows. That is, in the state shown in FIG. 21 (b), the water supply channel 12a is closed by the rotary valve body 13, and the hot water flowing in from the hot water inflow hole 11b remains as it is (without being mixed with water). It flows into the outflow channel forming body 21 from the hot water supply channel 12b through the opening 21a, flows downward, and flows out from the outflow hole 11c of the bottom member 11.

  The state shown in FIG. 21C is from the water-side rotation operation position of the temperature adjustment dial 9 shown in FIG. 21A to the hot water-side rotation operation position of the temperature adjustment dial 9 shown in FIG. The temperature control dial 9 is located between them, and the mixed water of water and hot water is discharged as water discharged from the valve device 5. In this state, as shown in FIG. 21 (c), the fan-like communication flow path 13 a of the rotary valve body 13 that rotates integrally with the temperature adjustment dial 9 is supplied from the water inflow hole 11 a of the bottom member 11 to the water. Is communicated with both the water supply flow path 12a of the fixed valve body 12 through which the water flows and the hot water supply flow path 12b of the fixed valve body 12 through which the hot water flows from the hot water inflow hole 11b of the bottom member 11. That is, in the state shown in FIG. 21C, the water flowing in from the water inflow hole 11a and the hot water flowing in from the hot water inflow hole 11b flow out from the water supply channel 12a and the hot water supply channel 12b, respectively, and are mixed. Then, it flows into the outflow channel forming body 21 through the opening 21a, flows downward, and flows out from the outflow hole 11c of the bottom member 11.

  And as shown in FIG.21 (c), in the state which the fan-shaped communication flow path 13a connected to both the water supply flow path 12a and the hot water supply flow path 12b which are long holes along a circular arc, Depending on the rotational operation position, the ratio of the communication areas of the water side and the hot water side, that is, the mixing ratio of water and hot water changes, and the water discharge temperature changes. In the examples shown in FIGS. 21A and 21B, the temperature adjustment dial 9 rotates counterclockwise, so that the water-side communication area increases and the hot water-side communication area decreases, and the water discharge temperature decreases. By rotating the dial 9 clockwise, the communication area on the water side decreases and the communication area on the hot water side increases, and the water discharge temperature rises.

  Next, switching of water discharge by pressing the flow control dial button 8 will be described. In switching the water discharge, the water stop state and water discharge state of the valve device 5 are alternately switched every time the flow control dial button 8 is pressed (see arrow X1 in FIG. 1).

  As shown in FIG. 22, in the water stop valve device 5, the opening 21 a is completely closed by the sliding valve body 22 located at the water stop position in the outflow passage forming body 21. That is, the opening 21 a that allows the communication flow path 13 a that forms the supply flow path of water, hot water, or a mixed water of water and hot water to face the outflow flow path forming body 21 slides in the outflow flow path forming body 21. It is blocked by the outer peripheral surface 22a of the sliding valve body 22, and the communication between the communication flow path 13a and the flow path in the outflow flow path forming body 21 is cut off.

  Further, as shown in FIG. 22, in the water stop valve device 5, the sliding valve vertical movement structure is located on the lower side, and the flow adjustment dial button 8 is housed in the recess 9 c of the temperature adjustment dial 9. Yes. In such a state, the upper surface 8f of the flow adjustment dial button 8 serving as the pressing operation surface is substantially flush with the upper surface 9f which is the upper end surface of the temperature adjustment dial 9 forming the recess 9c. Therefore, in the water stop state, the outer peripheral surface 8k, which is the rotational operation surface of the flow adjustment dial button 8, is hidden in the recess 9c, and the flow adjustment dial button 8 is in a state incapable of rotational operation.

  Further, as shown in FIG. 18, in the water stop valve device 5, as the state of the opening / closing mechanism 30, the rotation locking protrusions 135 of the rotor 35 are formed on the cam protrusions 234 of the cam groove forming member 34. The lower end recess is fitted and locked. Thereby, the raise of the sliding valve vertical movement structure by the urging | biasing force of the coil spring 32 is controlled, and the position of the sliding valve body 22 is hold | maintained in a water stop position.

  In such a water stop state of the valve device 5, when the flow control dial button 8 is pressed, the rotor 35 is predetermined by the meshing action of the upper and lower clutch tooth surfaces 35 c and 36 c in relation to the clutch ring member 36. The sliding valve vertical movement structure moves downward against the urging force of the coil spring 32 while receiving the action in the rotational direction. The rotor 35 receiving the action in the rotational direction along with the downward movement of the sliding valve vertical movement structure forms the lower side surface 135b of the rotation locking projection 135 and the lower end recess of the cam protrusion 234. It descends along the inner surface 234g.

  Then, when the upper end of the rotation locking projection 135 reaches the position of the lower end of the lower side piece 234c of the cam ridge 234, the rotor 35 is guided by the action in the rotation direction so that the guide slope of the rotation locking projection 135 is 135a is moved along the guide slope 234h to the adjacent cam groove 134 (see arrow C1 in FIG. 18), and the rotation locking projection 135 is locked, that is, the sliding valve up-and-down moving structure is restricted. Is released. As a result, the sliding valve up-and-down moving structure is moved upward by the urging force of the coil spring 32 with the rise along the cam groove 134 of the rotation locking projection 135.

  As the sliding valve vertical movement structure rises, the sliding valve body 22 in the outflow passage forming body 21 rises to the water discharge position where the opening 21a is opened, and the valve device 5 enters the water discharge state (see FIG. 23). ). Here, regarding the raising of the sliding valve vertical movement structure, the locking claw portion 37 d formed on the locking piece 37 c at the lower end portion of the operation member 37 is locked to the flange portion 34 d at the upper end portion of the cam groove forming member 34. As a result, the movement to the predetermined height position is limited.

  As shown in FIG. 23, in the valve device 5 in the water discharge state, the opening 21a is open because the slide valve body 22 is located in the water discharge position in the outflow channel forming body 21. That is, the opening 21a that opens the communication flow path 13a constituting the supply flow path of water, hot water, or a mixed water of water and hot water into the outflow flow path forming body 21 is opened, and the communication flow path 13a and the outflow flow path formation are formed. The flow path in the body 21 is in communication.

  Further, as shown in FIG. 23, in the valve device 5 in the water discharge state, the sliding valve vertical movement structure is located on the upper side, and the flow adjustment dial button 8 is mostly above the recess 9c of the temperature adjustment dial 9. To protrude. In this state, the upper surface 8 f of the flow adjustment dial button 8 serving as a pressing operation surface is at a position higher than the upper surface 9 f of the temperature adjustment dial 9. Moreover, the outer peripheral surface 8k which becomes a rotation operation surface of the flow tone dial button 8 is in a state of being exposed from the recess 9c, and the flow tone dial button 8 is in a state in which rotation operation is possible.

  Further, as shown in FIG. 19, in the valve device 5 in the water discharge state, as a state of the opening / closing mechanism portion 30, the rotation locking projection 135 of the rotor 35 is located in the cam groove 134, and the cam groove forming member 34 is located in the vicinity of the upper end of 34.

  In such a water discharge state of the valve device 5, when the flow adjustment dial button 8 is pressed, the rotor 35 is engaged with the clutch ring member 36 in accordance with the meshing action of the upper and lower clutch tooth surfaces 35c, 36c. While receiving the action in the rotational direction, the sliding valve vertical movement structure moves downward against the biasing force of the coil spring 32. With the downward movement of the sliding valve vertical movement structure, the rotor 35 descends while moving the rotation locking projection 135 along the cam groove 134 while receiving the action in the rotation direction, and the rotation locking projection. When the upper end of 135 reaches the lower end of the cam groove 134 (the position of the lower end of the upper-side piece 234b), the guide slope 135a of the rotation locking projection 135 is used to form a lower end recess of the cam projection 234. It rotates along the slope 234f.

  Then, the rotation locking projections 135 are fitted into the lower end recesses of the adjacent cam protrusions 234, and the locked state of the rotation locking projections 135, that is, the restricting state of the sliding valve vertical movement structure is obtained. As a result, the sliding valve up-and-down moving structure is held at the lower position while resisting the biasing force of the coil spring 32.

  Since the sliding valve vertical movement structure is located on the lower side, the sliding valve body 22 in the outflow passage forming body 21 is located at a water stop position where the opening 21a is closed, and the valve device 5 enters a water stop state. (See FIG. 22). As a result, the operation unit 6 of the valve device 5 is in a state where the upper surface 8 f of the flow adjustment dial button 8 and the upper surface 9 f of the temperature adjustment dial 9 form a substantially flush upper surface.

  Next, adjustment of the water discharge flow rate by rotating the flow adjustment dial button 8 will be described. Adjustment of the water discharge flow rate is performed by rotating the flow adjustment dial button 8 in a state of protruding from the recess 9c in the valve device 5 in the water discharge state (see arrow X3 in FIG. 3). In the rotation operation of the flow adjustment dial button 8, a knocking feeling due to the fitting shape between the operation tube portion 137 and the clutch ring member 36 as described above is obtained.

  In the valve device 5 in the water discharge state as shown in FIG. 19, by rotating the flow control dial button 8 in the protruding state in the direction (right rotation direction) to decrease the water discharge flow rate, the clutch ring member 36 is moved. The operating member 37 is rotated, and the clutch ring member 36 is pushed down with respect to the operating member 37 whose position in the vertical direction is fixed by the action of the lower inclined surface portion 36e and the upper inclined surface portion 137e. Against this, it gradually separates downward (see FIG. 20). Thereby, the sliding valve body 22 in the water discharge position moves downward integrally with the rotor 35 and the like, and the communication area between the communication flow path 13a and the outflow flow path forming body 21 through the opening 21a is gradually increased. To decrease. That is, the water discharge flow rate in the water discharge state gradually decreases.

  On the other hand, the operation member 37 is rotated with respect to the clutch ring member 36 by rotating the flow control dial button 8 in the protruding state in a direction (left rotation direction) for increasing the water discharge flow rate, and the lower inclined surface portion 36e. Due to the action of the upper inclined surface portion 137e and the urging force of the coil spring 32, the clutch ring member 36 gradually approaches the operation member 37 whose vertical position is fixed upward. Thereby, the sliding valve body 22 in the water discharge position moves upward integrally with the rotor 35 and the like, and the communication area between the communication flow path 13a and the outflow flow path forming body 21 through the opening 21a is gradually increased. To increase. That is, the water discharge flow rate in the water discharge state gradually increases.

  In the adjustment of the water discharge flow rate by the rotation operation of the flow adjustment dial button 8 as described above, with respect to the rotation direction (left rotation direction) of the flow adjustment dial button 8 that increases the water discharge flow rate, the lower inclined surface portion 36e of the clutch ring member 36 and The fitting state in which the upper inclined surface portion 137e of the operation member 37 is brought into contact with the step surfaces 36f and 137f is the closest state between the clutch ring member 36 and the operation member 37, and the rotational end of the flow control dial button 8 Become. In such a state, the sliding valve body 22 in the water discharge position is located at the rising end, the opening 21a is almost fully opened (see FIG. 23), and the water discharge flow rate is maximum.

  Further, with respect to the rotation direction (right rotation direction) of the flow adjustment dial button 8 that decreases the water discharge flow rate, the operation member 37 locks the locking claw portion 37d at the lower end thereof to the protrusion 34e on the outer peripheral side of the cam groove forming member 34. This state is the most separated state between the clutch ring member 36 and the operation member 37, and becomes the rotational end of the flow adjustment dial button 8. In such a state, the sliding valve body 22 in the water discharge position is located at the descending end, the opening 21a is slightly opened (see FIG. 24), and the water discharge flow rate is minimum.

  As described above, the water discharge flow rate adjusted by the rotation operation of the flow adjustment dial button 8 in the water discharge state is maintained without being affected by the pressing operation of the flow adjustment dial button 8 for switching the discharge water. That is, the adjustment of the water discharge flow rate by the rotation operation of the flow adjustment dial button 8 and the switching of the discharge water by the pressing operation of the flow adjustment dial button 8 are performed by the operation of each mechanism unit that operates independently. Yes, the position of the sliding valve body 22 in the vertical movement structure of the sliding valve according to the rotational position of the flow dial button 8 is determined by pressing the flow dial button 8 as long as the rotational position of the flow dial button 8 does not change. It is maintained regardless of switching of the water stop by operation.

  Therefore, the relative positional relationship in the vertical direction between the clutch ring member 36 and the operation member 37 that has changed with the adjustment of the water discharge flow rate by the rotation operation of the flow adjustment dial button 8 is the pressing operation of the flow adjustment dial button 8. Retained regardless. In the water stop state, the height position of the sliding valve vertical movement structure is defined in a state where the rotation locking projection 135 of the rotor 35 is fitted in the lower end recess of the cam ridge 234. The relative positional relationship between the clutch ring member 36 and the operation member 37 due to the rotation operation of the button 8 appears as the vertical position of the flow adjustment dial button 8 integrated with the operation member 37.

  As described above, in the valve device 5 of the present embodiment, the water discharge flow rate is adjusted by the rotation operation of the flow adjustment dial button 8 in the water discharge state, and after the water adjustment state is reached by the pressing operation of the flow adjustment dial button 8, In the case of the water discharge state, the rotational position of the flow adjustment dial button 8 in the previous water discharge state, that is, the water discharge flow rate is reproduced. The adjustment of the water discharge temperature by the rotation operation of the temperature adjustment dial 9 is performed by the operation of a mechanism that operates independently of the operation of the flow adjustment dial button 8, and depends on the rotation position of the temperature adjustment dial 9. The rotation position of the rotation valve body 13 is maintained regardless of the rotation operation and pressing operation of the flow adjustment dial button 8 as long as the rotation position of the temperature adjustment dial 9 does not change.

  According to the valve device 5 according to the present embodiment described above, it is possible to suppress changes in the setting of the water discharge flow rate and the water discharge temperature accompanying the switching operation of the discharge water, and to effectively use a small installation area. Can do.

  According to the valve device 5 according to the present embodiment, the adjustment of the water discharge temperature by the temperature adjustment valve unit 10 and the adjustment of the water discharge flow rate by the flow adjustment valve unit 20 are performed using the central axis O1 of the temperature adjustment dial 9 and the flow adjustment dial button 8. The flow control valve unit 20 can be operated by a rotation operation around the center, and the switching of the discharge water by the flow control valve unit 20 can be performed by a pressing operation that advances and retreats on the central axis O1 of the flow control dial button 8.

  That is, the operation direction of the temperature adjustment dial 9 as the temperature adjustment operation unit and the operation direction of the flow adjustment dial button 8 as the flow adjustment operation unit and the operation direction of the flow adjustment dial button 8 as the opening / closing operation unit intersect each other. Since they are different, it is possible to suppress the operation on the flow adjustment dial button 8 for switching the discharged water from affecting the adjustment of the discharged water temperature and the adjusted discharged water flow rate. Therefore, even if the flow control dial button 8 is pressed to switch the water discharge of the valve device 5, it is possible to suppress changes in the water discharge temperature and the water discharge flow rate, and the water stop operation is performed once in the water discharge state. When the water discharge operation is performed again after that, water discharge can be performed with the same water discharge flow rate and water discharge temperature setting as the previous time.

  Further, the flow adjustment dial button 8 that functions as an opening / closing operation section and a flow adjustment operation section, and the temperature adjustment dial 9 that functions as a temperature adjustment operation section are provided at a position having the central axis O1 as the central axis. The opening / closing operation unit, the flow adjustment operation unit, and the temperature adjustment operation unit in the apparatus 5 can be collectively installed at one place. Thereby, each operation part is independent, and installation with a small installation area becomes possible compared with the structure which installs each operation part separately.

  In the valve device 5 according to the present embodiment, the temperature adjustment dial 9 as the temperature adjustment operation unit is disposed on the outer peripheral side of the flow adjustment dial button 8 as the flow adjustment operation unit.

  According to such a configuration, the operation main body portion 9a of the temperature adjustment dial 9 constituting the operation portion as the temperature adjustment operation portion operates the flow adjustment dial button 8 constituting the operation portion as the flow adjustment operation portion. The dimension in the radial direction is larger than that of the main body portion 8a. For this reason, it becomes possible to finely adjust the water discharge temperature, and the water discharge temperature can be adjusted with high accuracy.

  Further, in the valve device 5 according to the present embodiment, the opening / closing operation unit and the flow adjustment operation unit are configured by a flow adjustment dial button 8 that is an integral operation member. The temperature adjustment dial 9 is accommodated in the recess 9c, and the flow adjustment dial button 8 protrudes from the recess 9c in the water discharge state. And the valve apparatus 5 is comprised so that the upper surface 8f of the flow control dial button 8 and the upper surface 9f of the temperature control dial 9 may be located on the substantially same plane in a water stop state.

  According to such a configuration, since the upper end surface of the flow adjustment dial button 8 is substantially flush with the upper end surface of the temperature control dial 9 in the water stop state, for example, the user's hand or the like is in the water stop state. It is possible to suppress unintentional flow adjustment operation (rotation operation) of the flow adjustment dial button 8 by hitting the flow adjustment dial button 8. Thereby, it can suppress that the water discharge flow rate from the last time of water discharge changes at the time of the next water discharge by operating the flow control dial button 8 unintentionally in a water stop state.

  Moreover, since the flow control dial button 8 protrudes from the upper end surface of the temperature control dial 9 when switching from the water stop state to the water discharge state, the user grasps the protruded flow control dial button 8 and rotates it. Thus, the water discharge flow rate can be adjusted. For this reason, favorable operativity can be obtained about adjustment of the discharged water flow rate. In addition, since the opening / closing operation unit and the flow adjustment operation unit are configured by an integral operation member, the number of components of the operation unit 6 of the valve device 5 can be reduced, and the configuration of the operation unit 6 can be simplified. Can do.

  Further, in the valve device 5 according to the present embodiment, the flow control valve section 20 includes an outflow flow path forming body 21 in which an opening 21a communicating with the flow path of the temperature control valve section 10 is formed, and an outflow flow path forming body. 21 has a sliding valve body 22 that changes the communication area of the opening 21a by moving forward and backward in the central axis direction to change the water discharge flow rate.

  According to such a configuration, the flow control valve unit 20 changes the opening area of the opening 21 a provided in the flow passage formed by the outflow passage forming body 21 by the sliding valve body 22, thereby Adjustment of the water discharge flow rate from the road and switching of water discharge can be performed.

  In the valve device 5 according to the present embodiment, the temperature control valve unit 10 includes a fixed valve body 12 in which a water supply channel 12a to which water is supplied and a hot water supply channel 12b to which hot water is supplied are formed. , A communication flow path 13a that communicates with at least one of the water supply flow path 12a and the hot water supply flow path 12b, and a rotary valve body 13 in which a through hole 13b is formed. The formed body 21 is disposed so as to communicate the opening 21a with the communication channel 13a.

  According to such a configuration, the temperature adjustment valve unit 10 that adjusts the mixing ratio of water and hot water and the flow adjustment valve unit 20 that adjusts the discharge water flow rate are partitioned by the outflow channel forming body 21. Therefore, it is possible to suppress the rotation of the rotary valve body 13 from being transmitted to the sliding valve body 22, and the mixing ratio of water and hot water, that is, the water discharge is performed by switching the water discharge and adjusting the water discharge flow rate. It can suppress that temperature changes.

  In addition, according to the valve device 5 of the present embodiment, the existing water discharge device in a bathroom vanity, a kitchen sink, or the like has a single lever mixing plug, for example, as a configuration provided with a valve device. Instead of the lever mixing plug, the valve device 5 of the present embodiment can be applied. That is, with respect to the configuration of the inlet and outlet holes for water and hot water with respect to the valve device 5, the single lever mixing plug including the existing valve device is connected to the main valve by sharing the valve device with the single lever mixing plug. It can replace with the valve apparatus 5 of embodiment. Specifically, by making the bottom member 11 having the water inflow hole 11a, the hot water inflow hole 11b, and the outflow hole 11c in the valve device 5 of the present embodiment common with the valve device of the single lever mixing plug, It becomes possible to replace the existing single lever mixing plug with the valve device 5 of the present embodiment.
