The inclined portions 48b and 48c of the ring member 48 are in contact with the inclined portions 48b and 48c of the ring member 48. The relative position in the axial direction between the rotation operation member 20 and the clutch ring member 48 is changed by changing the mutual axial distance from the 48c.
That is, the inclined portions 20a and 20b of the rotational operation member 20 and the inclined portions 48b and 48c of the clutch ring member 48 of the pressing operation unit 36 are caused by the rotational operation of the rotational operation member 20 when the pilot valve 32 is in the water discharge position. The rotary operation member 20 functions as a regulating means for regulating the amount of movement relative to the pressing operation unit 36 in the axial direction within a predetermined range.

Further, a protrusion 20c protruding in the inner circumferential direction from the outer periphery is provided at the end of the rotation operation member 20 on the pressure chamber forming member 28 side, and when the rotation operation member 20 rotates with respect to the cam groove forming member 38.

As shown in FIGS. 11 and 12, a flange 38e is provided at the end of the cam groove forming member 38 on the side of the opening / closing operation button 6 for currant.
In particular, as shown in FIGS. 5 and 6, when the pilot valve 32 is in the water stop position, the inclined portions 20 a and 20 b of the rotation operation member 20 and the inclined portions 48 b and 48 c of the clutch ring member 48 facing them are provided. Are in contact with each other, but the protrusion 20c of the rotation operation member 20 does not come into contact with the flange 38e of the cam groove forming member 38 regardless of the rotation operation of the currant flow adjustment dial 18. Therefore, when the water discharge device 1 is stopped, there is little wear due to mutual contact between the inclined portions 20a, 20b of the rotary operation member 20 and the inclined portions 48b, 48c of the clutch ring member 48, and the curling flow control dial 18 is relatively It can be operated with a small rotational operating force.

  On the other hand, as shown in FIGS. 7 and 8, when the pilot valve 32 is in the water discharge position, the inclined portions 20 a and 20 b of the rotation operation member 20 and the inclined portions 48 b and 48 c of the clutch ring member 48 facing them are provided. The protrusions 20c of the rotary operation member 20 are in contact with each other and the flange 38e of the cam groove forming member 38 is in contact with the pilot valve 32 shown in FIGS. Although a large rotational operation force is required at the time of rotating the curan flow adjustment dial 18, the water discharge state of the water discharge device 1 is temporary compared to the water stop state, regardless of the rotation angle of the curan flow adjustment dial 18. Since the rotational operation force is also substantially constant, it is possible to maintain good rotational operability of the currant flow adjustment dial 18.

The pilot valve 32 is connected to the end portion of the sliding member 42 of the pressing operation unit 36 connected to the end portion of the shaft 32a of the pilot valve 32 on the side of the open / close operation button 6 for the currant. A cap 50 for fixing to the sliding member 42 is attached.
Further, the rotation operation unit 40 of the valve operation unit 34 includes a compression coil spring 52 disposed between the cap 50 and the base end portion 20e of the currant flow adjustment dial mounting portion 20d of the rotation operation member 20, and includes a compression coil. The axial urging force that the spring 52 urges toward the rotation operation member 20 prevents axial rotation of the rotation operation member 20 with respect to the pressing operation unit 36, and according to the rotation angle of the rotation operation member 20, The position of the cap 50 in the axial direction is always positioned within the range between the base end portion 20e and the tip end portion 20f of the currant flow dial mounting portion 20d.

The main valve body 14a is formed with a bleed hole 14b through which hot water in the water passage 24b flows into the pressure chamber 26 and a pressure release hole 14c through which the hot water in the pressure chamber 26 flows into the water passage 24e.
A compression coil spring 32c is disposed between the shaft 32a of the pilot valve 32 and the valve portion 32b.
As shown in FIG. 5, in a state where the water discharge device 1 is stopped, the valve portion 32b of the pilot valve 32 closes the pressure release hole 14c by the urging force generated by the compression coil spring 32c being compressed. The shaft 32a of the pilot valve 32 is urged toward the opening / closing operation button 6 for currant.

Below, the effect | action of the water discharging apparatus 1 by one Embodiment of this invention mentioned above is demonstrated.
First, as shown in FIGS. 1 and 5, when the water discharge device 1 is in a water stop state and the curan flow adjustment dial knob 8 is set to the maximum flow rate setting position, the diaphragm 30 is connected to the main valve of the valve body 24. The seat 24c is seated and the main valve seat 24c is closed.
That is, hot water that has flowed into the water passage 24b from the main body inlet 2a of the water discharger main body 2 through the valve inlet 24a flows into the pressure chamber 26 through the bleed hole 14b provided in the main valve body 14a. The diaphragm 30 and the main valve body 14a are pressed toward the main valve seat 24c by the pressure of the hot water in 26, and the main valve seat 24c is closed.
Further, the valve portion 32b of the pilot valve 32 closes the pressure release hole 14c by the urging force of the compressed compression coil spring 32c.

At this time, the engaging protrusion 46b of the rotating ring member 46 is locked to the shallow groove 38a of the cam groove forming member 38, and the clutch tooth surface 46c of the rotating ring member 46 and the clutch tooth surface 48a of the clutch ring member 48 are Since they are engaged, the sliding member 42, the rotating ring member 46, and the clutch ring member 48 of the pressing operation unit 36 are fixed without moving in the axial direction and the rotating direction.
Further, the protrusion 6h of the door member 6a of the curan opening / closing operation button 6 abuts on the pressure receiving member 6g, and the pressing force distribution protrusion 6i of the pressure receiving member 6g corresponds to the convex portions 18a, 18b of the curan flow adjustment dial 18. The height of the inclined portion projecting toward the curran opening / closing operation button 6 is in contact with the end portions 18e and 18f having the maximum height.
At this time, the front surface of the door member 6 a of the curan opening / closing operation button 6 is substantially flush with the counter surface of the counter plate 4.

Next, as shown in FIG. 6, when the water discharge device 1 is in a water-stopping state and the currant flow adjustment dial knob 8 is set to the minimum flow rate setting position, the user rotates the currant flow adjustment dial knob 8. When operated, only the currant flow adjustment dial 18 and the rotation operation member 20 rotate integrally with the currant flow adjustment dial knob 8.
At this time, the respective inclined portions 20a and 20b of the rotation operation member 20 pass through the central hole 38d of the cam groove forming member 38 and contact the respective inclined portions 48b and 48c of the clutch ring member 48 in a fixed state. The rotation operation member 20 moves in the axial direction toward the curan opening / closing operation button 6 with respect to the clutch ring member 48, and the curan flow adjustment dial 18 together with the rotation operation member 20 rotates. 6 moves in the axial direction.
However, since the sliding member 42, the rotating ring member 46, and the clutch ring member 48 of the pressing operation unit 36 are fixed without moving in the axial direction and the rotating direction, the valve portion 32b of the pilot valve 32 is also released from the pressure. The hole 14c remains closed, and the diaphragm 30 and the main valve body 14a also remain closed with the main valve seat 24c.

Further, along with the rotation of the curan flow adjustment dial 18, the pressing force distribution protrusion 6i of the pressure receiving member 6g of the curan opening / closing operation button 6 causes the curans of both convex portions 18a, 18b of the curan flow adjustment dial 18 to be. The front surface of the door member 6a of the currant opening / closing operation button 6 is in contact with the start end portions 18c, 18d having the lowest height protruding toward the opening / closing operation button 6 side. It is almost flush with the counter surface.
That is, as shown in FIGS. 5 and 6, even if the flow control dial knob 8 is rotated while the water discharge device 1 is in the water-stopping state and the flow rate setting position is changed, In accordance with the rotation angle, the position where the pressing force dispersion projection 6i of the pressure receiving member 6g of the curan opening / closing operation button 6 abuts on both convex portions 18a, 18b of the curan flow dial 18 is changed. The distance between the dial 18 and the curan opening / closing operation button 6 is adjusted to be constant.

Next, when the user presses the opening / closing operation button 6 for currants in a state where the water discharging device 1 shown in FIG. 5 is in a water-stopping state and the currant flow adjustment dial knob 8 is set to the maximum flow rate setting position, FIG. As shown in FIG. 4, the water discharge device 1 is switched to the water discharge state, and the curan flow adjustment dial knob 8 is set to the maximum flow rate setting position.
At this time, by the pressing operation of the user, the door member 6a of the curan opening / closing operation button 6 rotates around the rotation shaft member 6b and is pushed into the currant flow control valve unit 14 side, and the protrusion of the door member 6a. 6h presses the pressure receiving member 6g toward the curan flow control valve unit 14 side.
Then, the pressing force dispersion protrusion 6i of the pressure receiving member 6g presses the end portions 18e and 18f of both convex portions 18a and 18b of the currant flow dial 18, and the currant flow dial 18 It translates integrally in the axial direction to the valve unit 14 side and is pushed into the flow control valve unit 14 side for curan.
As a result, the rotational operation member 20 of the curan flow control valve unit 14 is also pushed together with the curan flow control dial 18 to the main valve body 14a in the axial direction.

Further, when the rotation operation member 20 is pushed into the main valve element 14a in the axial direction, the sliding member 42, the rotation ring member 46, and the clutch ring member 48 of the pressing operation unit 36 disposed on the back side thereof are also axial. Is pushed into the main valve body 14a side. As a result, the engagement between the engaging protrusion 46b of the rotating ring member 46 and the shallow groove 38a of the cam groove forming member 38 is released, the rotating ring member 46 rotates by a predetermined angle, and the engaging protrusion 46b of the rotating ring member 46 is moved. It moves into the deep groove 38b of the cam groove forming member 38, and the sliding member 42 slides toward the curran opening / closing operation button 6 side by the urging force of the compression coil spring 44.
As a result, the sliding member 42, the rotating ring member 46, and the clutch ring member 48 of the rotating operation member 20 and the pressing operation unit 36 are integrally moved toward the curran opening / closing operation button 6 in the axial direction.

  At this time, the shaft 32a of the pilot valve 32 also moves together with the sliding member 42 to the curran opening / closing operation button 6 side, so that the valve portion 32b of the pilot valve 32 opens the pressure release hole 14c, and the hot water in the pressure chamber 26 flows. The pressure flows out from the pressure release hole 14c into the water passage 24e, and the pressure inside the pressure chamber 26 decreases. And the diaphragm 30 and the main valve body 14a leave | separate from the main valve seat 24c, and will be in the water discharge state.

  Further, as shown in FIG. 7, the projection 6h of the door member 6a of the curan opening / closing operation button 6 contacts the pressure receiving member 6g, and the pressing force distribution projection 6i of the pressure receiving member 6g The convex portions 18a and 18b are in contact with the end portions 18e and 18f having the maximum height of the inclined portions protruding toward the currant opening and closing operation button 6 side. Accordingly, the front surface of the door member 6 a of the curran opening / closing operation button 6 is slightly protruded to the front side from the counter surface of the counter plate 4.

Next, as shown in FIG. 8, when the water discharge device 1 is in a water discharge state and the currant flow adjustment dial knob 8 is set to the minimum flow rate setting position, the user rotates the currant flow adjustment dial knob 8. Then, the currant flow control dial 18 and the rotation operation member 20 rotate integrally with the currant flow control dial knob 8.
At this time, the rotational operation member 20 does not move in the axial direction with respect to the clutch ring member 48, and the respective inclined portions 20a, 20b of the rotational operation member 20 and the respective inclined portions 48b, 48c of the clutch ring member 48 They rotate relative to each other in contact with each other. The inclined portions 48b and 48c of the clutch ring member 48 are rotated by the inclined portions 20a and 20b of the rotating operation member 20 in contact with the clutch ring member 48, and the clutch ring member 48 is axially connected to the main valve body 14a. Pushed into the side.

Further, when the clutch ring member 48 is pushed into the axial main valve element 14a, the rotating ring member 46 and the sliding member 42 are also pushed into the axial main valve element 14a integrally with the rotating ring member 46. It is.
At this time, the engaging protrusion 46 b of the rotating ring member 46 is located in the middle of the deep groove 38 b of the cam groove forming member 38.

  Further, since the shaft 32a of the pilot valve 32 also moves to the main valve body 14a side together with the sliding member 42, the valve portion 32b of the pilot valve 32 is also applied to the curan flow shown in FIG. 7 by the urging force of the compression coil spring 32c. Compared to the case where the adjustment dial knob 8 is set to the maximum flow rate setting position, the pressure inside the pressure chamber 26 increases because the pressure release hole 14c is approached. Therefore, the diaphragm 30 and the main valve body 14a approach the main valve seat 24c, and the discharged water flow rate is reduced as compared with the case where the curan flow adjustment dial knob 8 shown in FIG. 7 is set to the maximum flow rate setting position.

  Further, as shown in FIG. 8, the projection 6h of the door member 6a of the curan opening / closing operation button 6 contacts the pressure receiving member 6g, and the pressing force distribution projection 6i of the pressure receiving member 6g Both convex portions 18a, 18b are in contact with the start end portions 18c, 18d having the lowest height of the inclined portions protruding toward the curran opening / closing operation button 6. Accordingly, the front surface of the door member 6 a of the curran opening / closing operation button 6 is slightly protruded to the front side from the counter surface of the counter plate 4.

When the user presses the curan opening / closing operation button 6 again, the rotation operation member 20 is integrally moved to the axial main valve body 14a side together with the curan flow adjustment dial knob 8 and the currant flow adjustment dial 18. It is pushed again.
As a result, the alignment between the engaging protrusion 46b of the rotating ring member 46 and the deep groove 38b of the cam groove forming member 38 is released, the rotating ring member 46 rotates by a predetermined angle, and the engaging protrusion 46b of the rotating ring member 46 becomes cam groove. Locked in the shallow groove 38a of the forming member 38. And again, the pilot valve 32 and the main valve body 14a are hold | maintained in the water stop position shown in FIG. That is, the valve portion 32b of the pilot valve 32 closes the pressure release hole 14c of the main valve body 14a, and the pressure in the pressure chamber 26 rises, so that the diaphragm 30 and the main valve body 14a are seated on the main valve seat 24c. It becomes a water stop state.

According to the water discharging device 1 according to the embodiment of the present invention described above, the projections 18a and 18b of the curan flow adjustment dial 18 and the pressing force distribution protrusion 6i of the pressure receiving member 6g of the curan opening / closing operation button 6 are Regardless of the rotation operation of the flow adjustment dial knob 8, the opening / closing operation for the curan is performed by functioning as an interval adjusting means for adjusting the interval between the opening / closing operation button 6 for the current flow and the flow adjustment valve unit 14 for the current flow. The distance between the operation button 6 and the curan flow adjustment dial 18 can be adjusted.
Therefore, even if the curan flow adjustment dial knob 8 is rotated without changing the axial position of the curan opening / closing operation button 6 to adjust the water discharge flow rate, for example, the water discharge device 1 is stopped. In the water state, the front surface of the door member 6a of the curran opening / closing operation button 6 is maintained substantially flush with the counter surface of the counter plate 4. Therefore, the surface on the front side of the door member 6a of the opening / closing operation button 6 for currants and the surface on the front side of the door member 10a of the opening / closing operation button 10 for shower arranged adjacent to each other are flush with each other. It can also be combined.
Furthermore, when the water discharge device 1 is in a water-stopped state, the curan opening / closing operation button 6 and the shower opening / closing operation button 10 can be prevented from projecting to the front side from the counter surface of the counter plate 4, and the curan in the projecting state can be prevented. It is possible to prevent the unexpected opening of the opening / closing operation button 6 and the shower opening / closing operation button 10 to damage the curran opening / closing operation button 6 and the shower opening / closing operation button 10.
Further, the projections 18a, 18b of the curan flow adjustment dial 18 and the pressing force distribution protrusions 6i of the pressure receiving member 6g of the curan opening / closing operation button 6 are independent of the rotation operation of the curan flow adjustment dial knob 8. By functioning as an interval adjusting means for adjusting the interval between the open / close operation button 6 and the curan flow control valve unit 14 to be constant, it is not necessary to change the design of the flow control valve units 14 and 16 themselves. It can be easily applied to existing flow control valve units.

  Moreover, according to the water discharging apparatus 1 by this embodiment, when a user presses the opening / closing operation button 6 for currants, the door member 6a is rotated by the rotating shaft member 6b without requiring excessive pressing force. Thus, the currant flow control dial 18 and the pressing operation unit 36 can be effectively pressed. Further, when the user presses the opening / closing operation button 6 for the curan, the curan flow adjustment dial 18 and the pressing operation unit 36 are effectively translated through the pressing force distribution protrusion 6i of the pressure receiving member 6g to discharge water. And water stop can be switched efficiently.

  Furthermore, according to the water discharging apparatus 1 according to the present embodiment, the currant flow adjusting dial 18 extends along the circumferential direction around the rotation center of the currant flow adjusting dial 18 on the surface of the currant opening / closing operation button 6 side. A plurality of projections 18a and 18b formed so as to protrude toward the curran opening / closing operation button 6 in a predetermined area and a pressing force distribution protrusion 6i of the pressure receiving member 6g of the curan opening / closing operation button 6 Since the interval adjusting means for adjusting the interval between the opening / closing operation button 6 and the curan flow control valve unit 14 to be constant can be realized with a simple configuration, the manufacturing cost can be suppressed.

Further, according to the water discharging device 1 according to the present embodiment, when the curan opening / closing operation button 6 is pressed, the pressure receiving member 6g of the curan opening / closing operation button 6 is pressed by the protrusion 6h of the curan opening / closing operation button 6. The pressure distribution protrusion 6i of the pressure receiving member 6g contacts the inclined portions 18g, 18h of the convex portions 18a, 18b of the currant flow dial 18 at a plurality of locations, so that the pressing force is applied to each inclined portion 18g, It is possible to disperse at a predetermined position of 18h. Therefore, it is possible to prevent damage to the currant opening / closing operation button 6 due to concentrated pressing force.
Furthermore, the area of the portion where the pressing force distribution protrusion 6i of the pressure receiving member 6g presses each of the inclined portions 18g and 18h is concentrated on one specific inclined portion and the area of the pressing force distribution protrusion 6i of the pressure receiving member 6g. Therefore, a more stable and reliable pressing operation can be performed.
Further, the pressure receiving member 6g is interposed between the protrusion 6h of the door member 6a and the inclined portions 18g, 18h of the convex portions 18a, 18b of the currant flow control dial 18, so that the protrusion 6h of the door member 6a becomes the pressure receiving member. In the case of pressing 6g, the protrusion 6h of the door member 6a directly presses the inclined portions 18g, 18h of the convex portions 18a, 18b of the currant flow dial 18 for the protrusion 6h of the door member 6a. It is possible to shorten the distance and time until the contact with each other and realize more reliable pressing operation. Therefore, the responsiveness of the operation when the user is performing the pressing operation can be improved, and a better operational feeling of the pressing operation can be given to the user.

  Further, according to the water discharging device 1 according to the present embodiment, when the curan opening / closing operation button 6 is pressed, the pressing force distribution protrusion 6i of the pressure receiving member 6g is formed on the protrusions 18a, 18b of the curan flow control dial 18. Since the plurality of inclined portions 18g and 18h abut at a plurality of locations, the pressing force can be distributed to a plurality of locations of the plurality of inclined portions 18g and 18h. Therefore, it is possible to prevent damage to the currant opening / closing operation button 6 due to concentrated pressing force. In addition, the area of the portion where the pressing force distribution protrusion 6i of the pressure receiving member 6g presses the plurality of inclined portions 18g, 18h is such that the pressing force distribution protrusion 6i of the pressure receiving member 6g contacts one inclined portion at one location. Since it becomes larger than the case, a more stable and reliable pressing operation can be performed.

  Furthermore, according to the water discharging device 1 according to the present embodiment, when the rotary operation member 20 of the valve operation unit 34 is rotated when the pilot valve 32 is in the water discharging position, the biasing force of the compression coil spring 44 is applied in a narrow space.
