  The rotation inducing member 42 is a substantially cylindrical part, and is attached inside the rotating cylinder member 32 so as to be sandwiched between the guide member 30 and the rotating cylinder member 32. A plurality of rotation induction teeth 42 a (FIG. 7) is formed on the tip side of the rotation induction member 42. The rotation inducing teeth 42a are configured to engage with the rotation ring 48 and rotate the rotation ring 48 by a predetermined angle when the valve operating member 34 is pushed in.

  The coil spring 44 is disposed between the disc portion 30 b of the guide member 30 and the feed screw member 46 so as to surround the guide portion 30 a of the guide member 30. Further, the coil spring 44 biases the feed screw member 46, the rotation ring 48, and the valve operation member 34 so as to protrude toward the distal end side.

  The feed screw member 46 is a substantially cylindrical member, and is disposed so as to surround the guide portion 30 a of the guide member 30. Further, a feed female screw portion 46 a that is screwed with the feed screw portion 38 a of the sliding member 38 is formed on the inner periphery of the feed screw member 46. For this reason, when the feed screw member 46 is rotated, the sliding member 38 guided by the guide portion 30a is slid in the axial direction by the feed female screw portion 46a. Further, a flange portion 46b is formed on the proximal end side of the feed screw member 46, the distal end of the coil spring 44 is in contact with the proximal end side of the flange portion 46b, and the rotating ring 48 is rotated on the distal end side. It is arranged to be movable. Further, four protrusions 46 c extending in the axial direction are formed on the outer peripheral side surface of the feed screw member 46. These projections 46c are respectively received in four axial grooves 34b (FIG. 6) formed on the inner periphery of the valve operating member 34, so that the feed screw member 46 and the valve operating member 34 are integrally formed. Turned and turned.

  The rotation ring 48 is a generally annular member, and is disposed so as to be rotatable around the feed screw member 46 and is in contact with the flange portion 46b. The rotating ring 48 is formed with four engaging claws 48a (FIG. 7) projecting radially. These engaging claws 48a are received in four of the eight latch grooves 32c formed in the inner periphery of the rotating cylinder member 32 and extending in the axial direction in the water discharge state. In this state, the rotation ring 48 is allowed to move to the distal end side of the rotary cylinder member 32. As a result, the valve operating member 34 and the feed screw member 46 that are moved together with the rotating ring 48 are also allowed to move to a position protruding from the rotating cylinder member 32 (FIGS. 3 and 6).

  On the other hand, the engaging claw 48 a of the rotating ring 48 is formed so as to come into contact with the rotation inducing tooth 42 a of the rotation inducing member 42 when the valve operating member 34 is pushed against the biasing force of the coil spring 44. ing. Since the tip of the rotation-inducing tooth 42a is formed to be inclined, when the engaging claw 48a is pressed against this, the rotation ring 48 is rotated by a predetermined angle. When the rotating ring 48 is rotated by a predetermined angle, the engaging claw 48 a is not aligned with the latch groove 32 c of the rotating cylinder member 32. For this reason, even after the valve operating member 34 and the feed screw member 46 are pushed back together with the rotating ring 48 by the urging force of the coil spring 44, the engaging claw 48a is engaged with the rotary cylinder member 32, and the valve operating member 34 is pushed in. Held in the position (FIG. 2).

  Next, when the valve operating member 34 is pushed in again and the engaging claw 48a comes into contact with the rotation inducing tooth 42a, the rotating ring 48 is further rotated by a predetermined angle. As a result, the engaging claw 48a is again aligned with the latch groove 32c of the rotating cylinder member 32. For this reason, the valve operating member 34 and the feed screw member 46 are moved to a position (FIGS. 3 and 6) projecting from the rotary cylinder member 32 by the urging force of the coil spring 44.

  Next, referring to FIGS. 2 to 5, the mounting structure of the open / close valve unit 10 to the water discharge device main body 2 and the operating force applied to the push button 6 and dial 8 by the user are transmitted to the open / close valve unit 10. The mechanism will be described.

  The valve presser 12 is formed in a substantially cylindrical shape, and is attached so as to surround the open / close valve unit 10. Further, a female screw 12 a is formed on the inner periphery of the valve presser 12, and the valve presser 12 is attached to the water discharger main body 2 by screwing it with a male screw formed on the water discharger main body 2. Further, since the end surface of the valve presser 12 is formed so as to engage with the shoulder of the valve cover 36 of the open / close valve unit 10, the open / close valve unit 10 is engaged by screwing the valve presser 12 into the water discharger body 2. Is fixed to the water discharge device main body 2.

The main body cover 14 is formed in a substantially cylindrical shape, and is attached so as to surround the valve presser 12.
The rotation transmitting member 16 is a generally annular component, and is attached to the front side of the main body cover 14 so as to be rotatable with respect to the main body cover 14. As shown in FIG. 4, two rotation transmission member notches 16 a are formed on the outer periphery of the rotation transmission member 16. The rotation transmitting member 16 is rotated together with the dial 8 by the rotation transmitting member notches 16 a receiving two dial protrusions 8 a formed inside the dial 8.

The holding ring 18 is an annular component and is attached to the back side of the rotation transmission member 16 to prevent the rotation transmission member 16 from falling off the main body cover 14.
The rotating collar 20 is a substantially cylindrical part, and is fitted on the outer periphery of the distal end portion of the rotary cylinder member 32 of the opening / closing valve unit 10. As shown in FIG. 4, a rotary collar notch 20 a extending in the axial direction of the opening / closing valve unit 10 is formed at one place on the circumference of the rotary collar 20. The rotating collar cutout portion 20 a receives an engaging protrusion 32 d formed on the outer periphery of the rotating cylinder member 32 and extending in the axial direction, whereby the rotating cylinder member 32 is rotated together with the rotating collar 20.

  Further, as shown in FIG. 4, a rotating collar projection 20 b extending outward in the radial direction is formed on the outer periphery of the rotating collar 20. The rotating collar protrusion 20b is received between a pair of rotation transmitting member protrusions 16b formed on the rotation transmitting member 16 and extending inward in the radial direction. It is rotated with.

  Accordingly, when the user rotates the dial 8, the dial 8, the rotation transmission member 16, and the rotation collar 20 are rotated together, and the rotary cylinder member 32 of the opening / closing valve unit 10 is rotated.

  On the other hand, a circumferential wall 16c of the rotation transmitting member 16 is received on the inner wall surface 6a of the push button 6 formed in a substantially cylindrical shape, whereby the push button 6 is slid in the axial direction of the opening / closing valve unit 10. It is supported movably. The push button 6 is arranged so that the back surface thereof is in contact with the end surface of the valve operating member 34 of the open / close valve unit 10. For this reason, when the push button 6 is pressed, the valve operating member 34 is pressed and translated in the axial direction.

  In addition, a positioning protrusion 6 b is provided on the back surface of the push button 6 so as to extend in the axial direction of the opening / closing valve unit 10. The positioning protrusion 6 b is received in a positioning recess 14 b provided on an arcuate wall 14 a extending from the main body cover 14 toward the push button 6. As a result, the rotational position of the push button 6 is positioned and the push button 6 is prevented from rotating. Therefore, the positioning protrusion 6b and the positioning recess 14b constitute a rotation locking means for preventing the push button 6 from rotating.

  Further, as shown in FIG. 5, an annular groove 6 c is provided on the outer periphery of the push button 6, while an annular groove 8 b is also formed at a corresponding position on the inner periphery of the dial 8. The C-ring 50 is received in both of these annular grooves 6c and 8b, and is disposed so as to straddle them. As a result, even when either the push button 6 or the dial 8 is pressed, they are integrally translated in the axial direction of the on-off valve unit 10.

Next, the effect | action of the water discharging apparatus 1 by 1st Embodiment of this invention is demonstrated.
First, as shown in FIG. 2, when the water discharge device 1 is in a water stop state, the diaphragm 26 is seated on the main valve seat 22b of the valve body 22, and the main valve seat 22b is closed. That is, the diaphragm 26 and the main valve body 28 are mainly driven by the pressure of hot water flowing into the pressure chamber 25 from the main body inlet 2a of the water discharger main body 2 through the valve inlet 22a and the small hole 28d provided in the main valve body 28. The main valve seat 22b is closed because it is pressed toward the valve seat 22b.

  Next, when the push button 6 is pressed by the user, the valve operating member 34 disposed on the back surface is also pressed in the axial direction. In addition, since the push button 6 and the dial 8 are configured to be integrally translated, the push button 6 is pushed even when the user presses the dial 8 portion. When the valve operating member 34 is pushed in, the rotating ring 48 disposed on the back side is also pushed in, and the engaging claw 48a of the rotating ring 48 comes into contact with the rotation-inducing tooth 42a of the rotation-inducing member 42. Thereby, the rotation ring 48 is rotated by a predetermined angle around the central axis of the opening / closing valve unit 10. Next, when the pressing force by the user does not act, the feed screw member 46, the rotating ring 48 and the valve operating member 34 are moved in a direction protruding from the counter plate 4 by the biasing force of the coil spring 44. Here, when the rotation ring 48 is rotated by a predetermined angle, the engaging claw 48 a is moved to a position aligned with the latch groove 32 c of the rotating cylinder member 32. As a result, the engaging claw 48 a is received in the latch groove 32 c, so that the feed screw member 46, the rotating ring 48 and the valve operating member 34 are moved to the position shown in FIG. 3 by the urging force of the coil spring 44.

  When the feed screw member 46 is moved to the position shown in FIG. 3, the sliding member 38 screwed to the feed screw member 46 and the pilot valve shaft 40 attached to the sliding member 38 are also moved together. When the pilot valve shaft 40 is moved, the reduced diameter portion 40a is aligned with the O-ring 28a attached to the main valve body 28. Thereby, the pressure release hole 28c of the main valve body 28 is opened, and the pressure inside the pressure chamber 25 is reduced. When the pressure in the pressure chamber 25 decreases, the diaphragm 26 and the main valve body 28 are separated from the main valve seat 22b, and a water discharge state is established.

  Next, when the user rotates the dial 8, the rotation transmission member 16, the rotation collar 20, the rotation cylinder member 32, the valve operation member 34 and the feed screw member 46 are rotated together. The push button 6 inside the dial 8 is prevented from rotating together with the dial 8 because the rotation is blocked by the positioning protrusion 6b and the positioning recess 14b.

  When the feed screw member 46 is rotated, the sliding member 38 screwed with the feed screw member 46 is moved in the axial direction by the feed screw. As a result, the pilot valve shaft 40 is also moved in the axial direction. Here, when the pilot valve shaft 40 is moved from the position shown in FIG. 3 to the back side (right direction in FIG. 3), the end of the reduced diameter portion 40a approaches the ring 28a, so that the pressure is released. The opening degree of the hole 28c decreases. As a result, the pressure in the pressure chamber 25 rises, the diaphragm 26 and the main valve body 28 are moved in the direction of the main valve seat 22b (the right direction in FIG. 3), and the flow rate of hot water flowing out from the on-off valve unit 10 is small. Become. Thus, since the diaphragm 26 and the main valve body 28 are moved so as to follow the movement of the pilot valve shaft 40, the discharge water flow rate is adjusted by the rotation of the dial 8.

  Next, when the user presses the push button 6 again, the valve operating member 34, the feed screw member 46, and the rotating ring 48 are pushed together with the push button 6 in the axial direction. As a result, the engaging claw 48a of the rotation ring 48 comes into contact with the rotation induction tooth 42a of the rotation induction member 42, and the rotation ring 48 is rotated again by a predetermined angle. Since the engaging claw 48 a is not aligned with the latch groove 32 c of the rotating cylinder member 32 by rotating the rotating ring 48 by a predetermined angle, the engaging claw 48 a is engaged with the rotating cylinder member 32. Thereby, the valve operating member 34, the feed screw member 46, and the rotating ring 48 are held at the water stop position shown in FIG. 2 against the urging force of the coil spring 44. In the state shown in FIG. 2, the pilot valve shaft 40 closes the pressure release hole 28c of the main valve body 28, so that the pressure in the pressure chamber 25 increases. Due to the pressure increase in the pressure chamber 25, the diaphragm 26 and the main valve body 28 are seated on the main valve seat 22b, and the water is stopped.

  According to the water discharging device of the first embodiment of the present invention, both the push button and the dial are translated, so that water discharge / water stopping can be switched even if the dial is pressed. Thereby, even if a push button and a dial are arrange | positioned collectively and a push button is reduced in size, the operativity which switches water discharge and water stop is not impaired.

  Moreover, according to the water discharging apparatus of this embodiment, since a push button is not rotated when a dial is rotated, the index which displays the function of an operation part, etc. can be provided in a push button.

  In the above-described first embodiment of the present invention, the dial is configured to grip and rotate its side, but as a modification, the dial can be configured as shown in FIG. In the faucet device of this modification, a large number of radial grip grooves 80b, which are grip means, are formed on the end face of the annular portion 80a of the dial 80 disposed around the push button 6 over the entire circumference. ing.

  According to the faucet device of this modification, the user not only holds the side surface of the dial 80 and rotates the dial 80 but also puts a finger on the end surface of the dial 80 to provide a jog dial provided in the AV device. The dial 80 can also be rotated as described above. Thereby, the operativity of a water discharging apparatus can further be improved.

  Further, in the first embodiment of the present invention described above, the push button and the dial are substantially flush with the counter plate in the water stop state and are configured to protrude in the water discharge state. The push button and the dial can always be substantially flush with the counter plate. 9 and 10 are cross-sectional views of the water discharger according to such a modification. FIG. 9 shows a water discharge state and FIG. 10 shows a water stop state, respectively.

  As shown in FIGS. 9 and 10, in the water discharging device according to this modification, a push button spring 90 which is an opening / closing operation unit return means is added between the rotation transmitting member 16 and the dial 80. The push button spring 90 is configured to urge the dial 80 and the push button 6 in a direction protruding from the counter plate 4. Further, the water discharging device according to this modification is positioned so that the end face of the dial 80 and the counter plate 4 are substantially flush with each other in the water discharging state. Accordingly, when adjusting the water discharge flow rate, the finger is put on the grip groove 80b (FIG. 8) on the end face of the dial 80 and rotated.

  In the water discharge state shown in FIG. 9, when the user presses the dial 80 or the push button 6, the dial 80 and the push button 6 are retracted to the back of the counter plate 4 to the position shown by the solid line in FIG. 10. Moreover, since the pressure release hole 28c of the main valve body 28 is closed by this pressing operation, the main valve body 28 is seated on the main valve seat 22b and is in a water stop state.

  Next, when the user releases his / her finger from the push button 6, the dial 80 and the push button 6 are returned to the original positions indicated by imaginary lines in FIG. 10 by the biasing force of the push button spring 90, and the counter plate 4 It becomes almost the same. On the other hand, the valve operating member 34 of the open / close valve unit 10 stops at the water stop position as described above. For this reason, in this modification, a gap is formed between the back surface of the push button 6 and the valve operating member 34 in the water stop state.

  According to the water discharging apparatus of this modification, the push button and the dial are always substantially flush with the counter plate, so that the appearance of the water discharging apparatus can be improved.

Next, with reference to FIG. 11, the water discharging apparatus by 2nd Embodiment of this invention is demonstrated.
The water discharging device according to the present embodiment is different from the first embodiment described above in that a restricting means for restricting the rotation range of the dial is provided. Accordingly, here, only the points of the present embodiment that are different from the first embodiment will be described, and the same components will be denoted by the same reference numerals and the description thereof will be omitted. FIG. 11 is a front view of the water discharger according to the second embodiment of the present invention.

  As shown in FIG. 11, the water discharge device 100 according to the second embodiment of the present invention includes a counter plate 104, a push button 6 that is an opening / closing operation unit protruding from the counter plate 104, and a flow rate operation unit that adjusts the water discharge flow rate. And the dial 108. Since the configuration and operation of the portion housed on the back surface of the counter plate 104 of the water discharge device 100 according to the present embodiment are the same as those of the first embodiment described above, description thereof will be omitted.

  The dial 108 includes an annular portion 108a formed so as to surround the push button 6, and a grip portion 108b formed so as to protrude radially outward from the annular portion 108a. Further, the counter plate 104 is formed with an arcuate rotation restricting cutout portion 104a for receiving the grip portion 108b of the dial 108.

  Here, when the water discharge device 100 is in a water discharge state and the push button 6 and the dial 108 are in a water discharge position that greatly protrudes from the counter plate 104, the grip portion 108 b formed on the dial 108 is in front of the counter plate 104. Protruding. For this reason, the user can rotate the dial 108 to a position where the grip portion 108b is disengaged from the rotation restriction notch 104a. On the other hand, when the water discharge device 100 is in a water stop state and the push button 6 and the dial 108 are in a water stop position where they do not protrude greatly from the counter plate 104, the grip portion 108b is received in the rotation restricting cutout portion 104a. It has been. Therefore, in this state, since the grip part 108b is engaged with the counter plate 104, the dial 108 cannot be rotated to a position where the grip part 108b is disengaged from the rotation restriction notch part 104a. That is, in a state where the push button 6 and the dial 108 are translated to the water stop position, the rotation of the dial 108 outside the predetermined region is prevented by the rotation restriction notch 104a.

  Further, in the water discharge state, when the dial 108 is rotated to a position where the grip portion 108 b is disengaged from the rotation restriction notch portion 104 a, the grip portion 108 b can be moved to the counter plate 104 even if the user presses the push button 6. Therefore, the push button 6 cannot be pushed into the water stop state. In this case, it is necessary to turn the dial 108 once to a position where the grip portion 108b falls within the range of the rotation restricting cutout portion 104a and then push the push button 6 into a water stop state. For this reason, when the water discharge device 100 is in a water stop state, the dial 108 is always set to a predetermined flow rate range, and the inconvenience that a large flow of hot water is unexpectedly discharged at the start of water discharge is avoided. can do.

  In the present embodiment, the water discharge flow rate is in the range of about 1 liter / min at which the water discharged from the water discharge device 100 is surely recognized by the user to about 9 liter / min that does not cause a problem even if the water is discharged unexpectedly. As described above, the rotation range of the dial 108 is restricted by the rotation restriction notch 104a. It is possible to prevent the user from being mistaken for a failure of the water discharge device 100 by unexpectedly discharging a large flow rate at the start of water discharge or by not starting water discharge even if the push button 6 is pressed.

According to the water discharging device of the second embodiment of the present invention, since the dial is provided with the grip portion protruding outward in the radial direction, the dial can be easily rotated.
Further, according to the water discharge device of the second embodiment of the present invention, it is possible to prevent the dial from being set at an excessive flow rate position in the water stoppage state, so that a large flow rate is unexpectedly started at the time of water discharge start. Inconvenience such as water discharge can be avoided.
