Description

  The present invention relates to a water faucet device, and more particularly to a remotely operated water faucet device in which a valve device is arranged separately from an operation device and the valve device is remotely operated by the operation device.

  Conventionally, the faucet device has an integral form in which the operation device is directly coupled to the valve device. In this case, for example, when installing the faucet device on the counter portion protruding from the wall surface of the bathroom to the indoor side, Therefore, the counter unit inevitably increases in size. As a result, the beauty and design around the installation part of the faucet device are impaired.

Moreover, in the conventional faucet device, since the direction of the operation device and the direction of the valve device need to match, the installation direction of the faucet device as a whole is limited, and the degree of freedom when installing the faucet device There was a problem that was low.
In this case, it is conceivable that the operation device and the valve device in the water faucet device are configured separately and arranged separately, and the valve device is remotely operated by the operation device.

For example, Patent Document 1 below discloses a box-type cock in which an operating device and a valve device are spaced apart and the valve device is remotely operated by the operating device.
In the one disclosed in Patent Document 1, the operating force applied to the operating portion is transmitted from the rack member to the pinion gear, further from the pinion gear to the rack member, and further from the rack member to the pinion gear to operate the rotary valve body. Like that.

  The one disclosed in Patent Document 1 is intended only to open and close the valve body, and therefore, the operation force applied to the operation portion is simply transmitted between the pinion gear and the rack member to achieve the purpose. However, in a faucet device that requires flow rate adjustment, if the transmission path of the operating force from the operating device to the valve device is simply composed of these pinion gears and rack members, the gears and gears mesh. The gap (play) generated based on the backlash of the part causes a so-called hysteresis phenomenon that causes the flow rate to differ between when the flow rate is increased and when the flow rate is increased even if the operation position of the flow control unit is the same. This will reduce the performance of the faucet device.

  In the case of such an operating force transmission mechanism by meshing the pinion gear and the rack member, the operating energy applied to the operating device is caused by friction or slippage between the gear tooth surfaces and between the gears and the gears. There is a problem that the efficiency of the transmission of the operating force is low, and it is necessary to apply a large operating force, or it is difficult to accurately transmit the operating force to the valve device. There is.

They are respectively arranged on counter portions protruding from the wall to the indoor side, and the transmission mechanism is vertically connected to the operating device and the valve device.

Effects and effects of the invention

As described above, according to the first aspect of the present invention, the operation device provided with the rotation operation unit for adjusting the valve opening amount of the valve body and the valve device are separated and separately installed. According to this invention, the freedom degree of the layout at the time of installation of a faucet device can be raised.
In addition, the valve device need not be installed at the place where the operating device is installed, and the valve device can be provided in a different location and in a concealed state. It is possible to improve the aesthetics and design around the place where the faucet is installed.

According to the first aspect of the present invention, the operating force applied to the operating device is transmitted to the valve device via a transmission mechanism having a swinging member capable of seesaw motion. According to the first aspect, as compared with the case where the operating force is transmitted by meshing the pinion gear and the rack gear as the transmission mechanism, the transmission efficiency of the operating force to the valve device is high, and therefore the valve device can be operated with a small operating load. It is possible to make the operating device thin.
Further, in the transmission mechanism having the swing member, the required number of parts can be suppressed to the minimum necessary, the number of parts of the faucet device as a whole can be reduced, and the cost of the faucet device can be reduced.

  According to the first aspect of the present invention, when the rotation operation of the rotation operation unit is performed, the action point on the one end portion of the swing member on the operation device side is linearly parallel to the rotation axis of the rotation operation unit by an amount corresponding to the rotation operation amount. A motion conversion member is provided in the operating device to move the swinging member continuously around the axis and in an amount corresponding to the rotational operation amount of the rotary operation unit, and the operating force transmission mechanism is provided by the swinging member. Based on the continuous rotational movement around the axis of the valve body, the valve body is continuously moved forward and linearly by an amount corresponding to the rotational operation amount at the other end on the valve device side, and the valve opening amount of the valve body Another feature is that it is continuously changed.

  When the valve body in the valve device is simply opened and closed, the operating device is provided with a pushing operation part, and the pushing operation part linearly pushes the end of the rocking member on the operating device side. It is usually conceivable to transmit force to the valve body.

However, when it is necessary to move the valve body slightly, for example, when adjusting the flow rate, the valve body moves greatly due to slight pressing of the pressing member. It is difficult to adopt the operating force transmission method as it is.
In such a case, it is extremely difficult to finely adjust the position of the valve body, that is, the valve opening amount of the valve body, and the position of the valve body greatly changes even if the pushing member is slightly operated. It becomes difficult to discharge water at a flow rate.

  Here, in the first aspect of the present invention, an operation unit for adjusting the valve opening amount of the valve body is provided in the operation device as a rotation operation unit, and the amount corresponding to the operation amount is obtained by the rotation operation of the rotation operation unit. A motion converting member that linearly moves the point of action on the one end of the swinging member in a direction parallel to the rotational axis of the rotating operation unit. With such a motion converting member, the rotational motion of the rotating operation unit is temporarily After converting into a linear motion of the action point, it is converted into a rotational motion of the swinging member, and this causes the swinging member to rotate slightly, and more specifically, the shaft of each end of the swinging member. The surrounding position is slightly changed, and the valve opening amount of the valve body is continuously changed.

Generally, the more the swing member is tilted, the worse the transmission efficiency of the operation amount to the valve body.
However, in the case of the first aspect, even when the rotation operation unit is largely rotated, the linear movement amount (distance) of the action point of the motion conversion member can be easily increased even if the operation force input unit is rotated and moved in detail. Can be reduced.
As a result, high transmission efficiency can be maintained.
Further, the rotational angle position around the axis of the swinging member can be minutely changed, and accordingly, the position of the valve body can be delicately changed accordingly.

  Therefore, when this claim 1 is applied to a water supply device such as a single water faucet device that changes water supply, water supply stoppage, and water supply amount, and the rotation operation unit is configured as a flow control operation unit, the flow is controlled by operating the rotation operation unit. When adjusting, the flow rate of discharged water can be changed and adjusted subtly based on the rotation operation of the rotation operation unit.

  Further, according to claim 1, there is provided a hot water mixing which has a hot water side valve body and a water side valve body, and changes the valve opening amount in a reverse relationship with each other to change the mixing ratio of hot water (that is, the temperature of the mixed water). When applied to a valve device and the rotation operation unit is configured as a temperature adjustment operation unit that changes the temperature of the mixed water, for example, by adjusting the valve opening amount of the hot water valve body, the temperature of the mixed water is controlled by operating the rotation operation unit. Can be changed and adjusted subtly.

  In this case, the motion conversion mechanism is provided with a rotating cam that rotates with the rotation of the rotating operation unit, and the contact point of the cam member on the operating device side of the swing member is set as the rotation axis of the rotating operation unit. However, according to claim 2, the motion converting member is linearly moved by screw feed by the rotation operation of the rotation operation unit. It can have an action axis (claim 2).

  In this way, the rotary motion of the rotary operation unit can be effectively converted into the linear motion of the motion conversion mechanism, and even if the rotary operation unit is largely rotated, the action axis is in accordance with the operation amount. It can be linearly moved by a small amount (distance), thereby slightly changing the position of each end of the rocking member and accompanyingly changing the position of the valve body to adjust the valve opening amount. It can be performed.

Next, according to a third aspect of the present invention, the motion converting member is provided with a rotating member that is screwed onto the action shaft, rotates with the rotation of the rotation operation unit, and linearly moves the action shaft by screw feed, and rotates with the action shaft. In addition to constituting a telescopic shaft that expands and contracts as a whole with the member, the operating device is provided with a push operating portion as an operating portion that opens and closes the valve body, and a pushing member that performs a pushing motion with respect to this push operation. The push-in movement of the push-in member by the push operation on the operation unit and the pull-in movement from the push-in position to the pull-in position allow the set shaft to move forward and backward as a whole without extending or retracting the telescopic shaft, and the above transmission By the mechanism, the operation of the push operation unit is transmitted to the valve body by the rotational movement around the axis of the swinging member, and the position of the valve body is switched between the valve opening position and the valve closing position. One in which the.
According to the third aspect of the present invention, the operations applied to the rotation operation unit and the push operation unit can be transmitted to the valve body through the swing member, thereby adjusting the valve opening amount of the valve body. Can also be opened and closed.

In this case, claim 3 can be applied to a water supply device such as the above-described single water faucet device, and the push operation unit can be configured as a water discharge operation unit, and water discharge can be performed by the push operation. .
Further, the push operation unit is configured as an open / close operation unit that opens and closes the hot water side valve body, for example, and the hot operation side valve body is opened by the push operation unit. By switching the state to the valve closed state, the hot water / water mixing valve device can be switched between a mixed water discharge state and a water discharge state in which only water is discharged.

In the faucet device according to the third aspect, after the telescopic shaft is set in a predetermined telescopic state by the operation of the rotary operation unit, the set stroke is maintained while maintaining the expansion / contraction amount by the operation of the push operation unit. In the faucet device according to claim 3, when the valve body is switched from the closed state to the open state, the valve opening that has been adjusted in advance is moved forward and backward. The valve body can be opened by the amount.
Therefore, in the above-described single water faucet device or the like, when the state is switched from the water stop state to the water discharge state, water discharge can be performed at a previously adjusted flow rate.
In the hot water mixing valve device, for example, when the hot water side valve body is switched from the closed state to the open state, that is, when the state is switched from the water spouting state to the mixed water spouting state, the mixed water temperature that has been adjusted in advance. The mixed water can be discharged.

  According to the third aspect of the present invention, there is provided a latch mechanism for switching the position of the pushing member between the pushing position and the drawing position and holding the position each time the push operation section is pushed, and the operating mechanism is provided with the latch mechanism. (Claim 4).

In this way, when the valve element is switched between the open state and the closed state by the operation of the push operation unit, it is possible to maintain the open state and the closed state thereafter by the latch mechanism. It becomes.
In addition, since the latch mechanism is provided on the operating device side, the feeling of switching by the latch mechanism is directly transmitted to the hand, and the user can directly feel that the switching operation has been performed. Can make you feel.

In the present invention, a spring for urging the valve body in the retracting direction in the valve opening direction is provided on the valve device side, and the spring is used for operating the latch mechanism that exerts a urging force on the operating device side through the transmission mechanism. It can be a spring (Claim 5).
In this way, it is not necessary to separately provide a spring for biasing the valve body toward the swinging member and transmitting the operating force to the valve body and a spring for operating the latch mechanism. The number of springs can be reduced.

In the present invention, the valve device has a main valve body and a pilot valve body, and the main valve body is moved in the same direction following the forward and backward movement of the pilot valve body while forming a minute gap between the valve body and the pilot valve body. And a transmission mechanism connected to the pilot valve body so as to transmit the operating force to the pilot valve body (claim 6).
In this way, the required operating force can be further reduced, and further light operations can be realized.
Further, the strength of the member that transmits the operating force can be reduced, and the required cost can be reduced.

  In the present invention, the valve device is housed in a basin table that protrudes indoors from the bathroom wall, and the operation device is provided in a counter unit that protrudes from the wall to the indoor side above the basin table. The upper operating device and the lower valve device can be connected by a transmission mechanism.

  By doing in this way, compared with the case where a faucet device having a valve device and an operation device is installed in one specific counter unit in the bathroom, the counter unit on the installation side of the operation device that appears on the appearance is made compact. It can comprise, and the aesthetics and designability of the installation part of a faucet device can be improved.

Next, embodiments of the present invention will be described in detail with reference to the drawings.

It is preferable to discharge the mixed water from the water discharge pipe 8.

As shown in FIG. 2, a valve device 10 in the faucet device 6 is accommodated inside the basin table 5, and the valve device 10 and the operation device 7 are connected to each other inside the communication unit 4. 12 is operably connected up and down.
Here, the transmission mechanism 12 transmits the operating force applied to the operating device 7 to the valve device 10 to operate the valve device 10.
Reference numeral 90 denotes a support member provided in the transmission mechanism 12.

The structure of the valve device 10 is specifically shown in FIGS.
FIG. 4 shows a state when the water is stopped, and FIG. 5 shows an enlarged main part of FIG.
Moreover, FIG. 6 represents the state at the time of water discharge.
In these drawings, reference numeral 16 denotes a body in the valve device 10, in which a primary inflow passage 18 and a secondary outflow passage 20 forming a main water channel are formed.
In addition, 22 is an inflow port and 24 is an outflow port.

In this embodiment, the entire valve mechanism is configured as a detachable valve cartridge as a single unit. In the figure, reference numeral 26 denotes a cartridge case of the valve cartridge. The cartridge case 26 is divided into a left part 26-1 and a right part 26-2 in the figure, and they are arranged in the middle part of the cartridge case 26. The back pressure chamber forming member 28 described later is elastically connected.
The valve cartridge is fixed in the removal state by screwing the fixing nut 30 into the body 16 while being inserted into the body 16.

In FIG. 5, 32 is a main valve element comprising a diaphragm valve element provided on the main water channel, and comprises a resin-made hard main valve body 34 and a rubber diaphragm film 36 held thereby. .
The main valve body 32 moves back and forth in the left-right direction in the figure with respect to the main valve seat 38 to open and close the main water channel, and to change the opening of the main water channel.
Specifically, the main water channel is blocked by sitting on the main valve seat 38, and the main water channel is opened by separating from the main valve seat 38 leftward in the figure.
Moreover, the opening degree of the main water channel is changed in magnitude according to the distance from the main valve seat 38, and the flow rate of water flowing through the main water channel, that is, the flow rate from the water discharge portion is adjusted.

A back pressure chamber 40 is formed behind the left side of the main valve body 32 in the figure.
The back pressure chamber 40 causes the internal pressure to act on the main valve body 32 as a pressing force in the valve closing direction rightward in the drawing.
The main valve body 32 is provided with an introduction small hole 42 that passes through the main valve body 32 and allows the primary inflow passage 18 and the back pressure chamber 40 to communicate with each other.
The introduction small hole 42 guides water from the inflow passage 18 to the back pressure chamber 40 and increases the pressure of the back pressure chamber 40.

The main valve body 32 is also provided with a pilot water channel 44 as a water drainage channel that passes through the main valve body 32 and communicates the back pressure chamber 40 and the secondary outlet channel 20.
The pilot water channel 44 reduces the pressure in the back pressure chamber 40 by drawing the water in the back pressure chamber 40 into the outflow passage 20.

  As shown in FIG. 5, the main valve body 32 is provided with a through-hole penetrating in the axial direction at the center thereof, and the discharge water pilot valve body and the flow control pilot valve body are provided there. The common pilot valve body 46 that also serves as the pilot valve body 46 is inserted, and the pilot water passage 44 having a narrow passage width is formed between the outer peripheral surface of the pilot valve body 46 and the inner peripheral surface of the through hole.

As shown in FIGS. 7 and 8, the main valve body 32 is integrally provided with a pilot valve seat 48 having an annular shape around the axis of the main valve body 32 along the inner peripheral surface of the through hole. ing.
Reference numeral 50 denotes a seal portion in the pilot valve seat 48, which holds an O-ring 52 as an elastic seal ring having an annular shape inside the annular groove.

The pilot valve body 46 is fitted to the pilot valve seat 48 so as to be movable back and forth in the left-right direction in the drawing along the axis of the main valve body 32.
Specifically, the pilot valve body 46 has a circular cross section and has a seal portion 54 having the same outer diameter in the left-right direction, that is, in the forward / backward direction in the drawing, and the distal end side (lower side in FIG. 7, right side in FIG. 5) And an annular recess 56.
Each end of the annular recess 56 in the axial direction is a tapered surface that gradually decreases in diameter toward the smallest diameter portion of the recess 56, and a stepped portion is provided at each end on the large diameter side of the tapered surface. 58 and 60 are formed.

4 and 5, the pilot valve body 46 is closed. At this time, the pilot valve body 46 has a seal portion 54 over the entire circumference with respect to the pilot valve seat 48 via the O-ring 52. The pilot valve body 46 and the pilot valve seat 48 are in a state of being sealed in a watertight manner by elastic contact in the radial direction.
At this time, the main valve body 32 is seated on the main valve seat 38, and the main water channel is closed.

7 and 8 show the action during flow adjustment (flow rate adjustment) by the movement of the pilot valve body 46.
In this embodiment, the pilot valve body 46 does not close the pilot water channel 44 during flow adjustment, and only the opening degree of the pilot water channel 44 is changed by the movement.
A rotation operation amount with respect to a rotation operation unit 180 described later is so regulated.

In this embodiment, as shown in FIG. 7 (I), when the pilot valve body 46 moves backward upward (leftward in FIG. 5), the gap between the pilot valve body 46 and the pilot valve seat 48 Is temporarily increased, and a large amount of water in the back pressure chamber 40 escapes to the outflow passage 20 side through the pilot water channel 44 and the pressure in the back pressure chamber 40 decreases.
Therefore, the main valve body 32 moves upward in the figure due to the pressure difference with the inflow passage 18, and the pressure of the inflow passage 18 and the pressure of the back pressure chamber 40 are balanced as shown in FIG. 7 (II). The backward movement of the main valve body 32 stops at the position where it moves.
That is, the main valve body 32 moves backward together so as to follow the backward movement of the pilot valve body 46, and the main valve body 32 also stops when the pilot valve body 46 stops.
At this time, a minute gap (following gap) is maintained between the pilot valve body 46 and the main valve body 32.
Thereafter, the main valve body 32 moves together with the pilot valve body 46 while maintaining this constant minute gap.

  By the backward movement of the main valve body 32, the gap between the main valve body 32 and the main valve seat 38 becomes large, and the amount of water flowing from the inflow passage 18 into the outflow passage 20 increases.

  From this state, when the pilot valve body 46 is further moved backward in the figure, the main valve body 32 moves backward from the pilot valve body 46 so that the pressure in the back pressure chamber 40 and the pressure in the inflow passage 18 are balanced. Following the movement, the vehicle moves backward to increase the flow rate of water flowing through the main water channel by further widening the opening of the main water channel (see FIG. 7 (III)).

  On the other hand, when the pilot valve body 46 moves forward downward in the drawing as shown in FIG. 8 (I), between the pilot valve body 46 and the pilot valve seat 48, more specifically, the seal portion 54 in the pilot valve body 46 and The gap between the pilot valve seat 48 and the O-ring 52 is temporarily reduced, that is, the opening of the pilot water passage 44 is reduced, and the amount of water flowing from the back pressure chamber 40 to the outflow passage 20 is reduced. The pressure in the back pressure chamber 40 decreases and increases.

For this reason, the main valve element 32 is now moved forward downward in the figure (rightward in FIG. 5) by the increased pressure, and stops at a position where the pressure of the back pressure chamber 40 and the pressure of the inflow passage 18 are balanced. .
Also at this time, a constant minute gap (following gap) is maintained between the pilot valve body 46 and the main valve body 32.
When the pressure in the back pressure chamber 40 temporarily increases in this way, the main valve body 32 moves forward downward in the figure due to the increased pressure, and the pressure in the back pressure chamber 40 and the pressure in the inflow passage 18 are reduced. Stop at the position to balance.
At this time, the gap between the main valve body 32 and the main valve seat 38 is reduced, that is, the opening of the main water passage is reduced, and the flow rate of water flowing through the main water passage is reduced (see FIG. 8 (II)). .

  When the pilot valve body 46 further moves downward in the figure from this state, the opening of the main water channel is further reduced, and the flow rate of water flowing through the main water channel is further reduced (see FIG. 8 (III)).

In FIG. 5, reference numeral 28 denotes a back pressure chamber forming member having an inverted cup shape, and the back pressure chamber 40 is formed inside thereof.
The back pressure chamber forming member 28 also serves as a main valve body presser.

The back pressure chamber forming member 28 holds an O-ring 64 as an annular seal ring having a pair of elasticity.
These O-rings 64 are in elastic contact with the outer peripheral surface of a valve shaft 66, which will be described later, over the entire circumference, and provide a watertight seal between the valve shaft 66 and the back pressure chamber forming member 28, that is, between the back pressure chamber 40. To do.
Note that an O-ring 68 is also held on the outer peripheral surface of the right portion 26-2 of the cartridge case 26, and the space between the body 16 and the body 16 is sealed with the O-ring 68.

In FIG. 5, the valve shaft 66 extends in the axial direction with a uniform circular cross section and a uniform outer diameter, and the pilot valve body 46 is integrally formed at the end of the valve shaft 66.
An elastic retaining ring 62 made of an E ring is attached to the right end of the valve shaft 66 in FIG. The retaining ring 62 has a larger diameter than the through hole formed in the central portion of the main valve body 46.

As shown in FIGS. 4 and 6, an advance / retreat rod (advance / retreat member) 70 that moves forward / backward in the same direction as the valve shaft 66 is connected to the left end portion of the valve shaft 66 by a spherical bearing 74. 70 and the valve shaft 66 are integrally moved linearly in the left-right direction in the figure.
Reference numeral 72 denotes a cylindrical guide member into which the advance / retreat rod 70 is fitted. The advance / retreat rod 70 slides in the left-right direction under the guidance of the guide member 72.
Reference numeral 76 denotes a cylindrical housing that accommodates the advance / retreat rod 70 and the guide member 72 therein, and the right end in the figure is fixed to the valve mechanism by screw connection, specifically to the body 16.

A spring receiving portion 78 having a larger diameter than this is provided at the left end portion of the advance / retreat rod 70 in the drawing, and a coil spring 80 is interposed between the spring receiving portion 78 and the guide member 72. The urging force is exerted on the forward / backward rod 70 and the valve shaft 66 in the direction in which the pilot valve body 46 is opened.
The direction of the urging force is opposite to the direction in which the operating force applied in the operating device 7 is applied to the valve device 10, specifically the pilot valve body 46.

In FIG. 3, the transmission mechanism 12 that transmits the operating force applied by the operating device 7 to the valve device 10 has a longitudinal shape in the vertical direction in the figure, and a swing bar (swinging motion) that can perform a seesaw motion around the shaft 82.

The action shaft 104 is clamped by the pair of clamping pieces 124 of the locking member 122 shown in FIG. 13 at the engaging portion 118, and the action shaft 104 is prevented from rotating by the clamping action of the clamping pieces 124. .

That is, due to the rotation preventing action of the rotation preventing member 122, the action shaft 104 is moved forward and backward by screw feed in the left and right directions in FIGS.
As the operating shaft 104 moves forward in the left direction and moves backward in the right direction in the drawing, the swinging bar 84 is turned (swinged) counterclockwise and clockwise in the drawing. The pilot valve body 46 is moved back and forth in the left-right direction in the drawing.

  Here, the rotation-preventing member 122 has a circular pedestal portion 134, and this pedestal portion 134 is fixed to the support member 90 of the transmission mechanism 12 with screws 132.

The driving mechanism 102 also has a push button (pushing member) 126 having a bottomed cylindrical shape, a rotating sleeve 129 and a rotor 128, and a thrust lock mechanism (latch) is constituted by these elements and the coil spring 80. Mechanism) 127 (FIGS. 11 and 12).
The rotating sleeve 129 is a part that adjusts the flow rate by moving the main valve body 32 following this by moving the pilot valve body 46 forward and backward as shown in FIGS. 7 and 8 by rotation. The push button 126 is a part for switching the position of the pilot valve body 46 between the valve closing position as the forward movement position and the valve opening position as the backward movement position for each depression.

As shown in FIG. 12, the rotation sleeve 129 has a base end portion which is assembled to the base portion 130 of the operating device 7 so as to be rotatable in an internally fitted state and in a retaining state.

The rotor 128 is formed of a ring-shaped member, and engaging teeth 152 that protrude upward in the figure in a mountain shape are provided at a plurality of circumferential positions (here, four positions).
In addition, engaging teeth 154 having a sawtooth shape protruding outward are provided at the same place in the circumferential direction.

The inner engagement tooth 152 has a first driven cam surface 156 corresponding to the drive cam surface 150 of the push button 126 on the upper surface along one oblique side.
Here, the inclination angle θ ₁ of the first driven cam surface 156 is the same as that of the drive cam surface 150 on the push button 126 side.

On the other hand also in the outside of the engaging teeth 154, the upper surface along its hypotenuse is the second driven cam surface 106 which is inclined at an angle theta _2.
In this embodiment, the first driven cam surface 156 Yes inclined angle so that different the second driven cam surface 158, the inclination angle theta ₂ of the second driven cam surface 158 forms an acute angle, the contrast 1 the inclination angle theta ₁ of the driven cam surface 156 is a small angle.

As shown in FIGS. 11, 12, and 13, the rotor 128 has its lower surface (see FIG. 13) supported by the upper surface of the outward flange portion 160 of the rotating member 114, and the flange portion. The upper surface of 160 rotates and slides in the direction of the arrow shown in FIG.
The urging force of the coil spring 80 is exerted on the rotating member 114 upward in FIG. 13 (rightward in FIG. 12) via the swing bar 84 and the action shaft 104. That is, the urging force of the coil spring 80 is exerted on the rotor 128 and the push button 126 via the rotating member 114 in the backward direction toward the right in FIG. 12 and upward in FIG.

As shown in detail in FIG. 13, the rotating sleeve 129 is provided with a guide portion 162 projecting inwardly on an upper inner peripheral surface thereof.
The guide portion 162 has engaging teeth 164 at the lower end.
An inclined guide cam surface 166 corresponding to the second driven cam surface 158 of the rotor 128 for rotating the rotor 128 by cam action is also formed on the lower surface of the engagement tooth 164.
Here, the inclination angle of the guide cam surface 166 is the same as that of the second driven cam surface 158 of the rotor 128.
In the guide portion 162, the insertion grooves 146 extending in the vertical direction as described above are formed at predetermined intervals in the circumferential direction. When the rotor 128 is in a rotational position in which the engaging tooth 154 having an outward projecting shape is positioned in the insertion groove 146, the engaging tooth 154 is inserted into the insertion groove 146 in the drawing. An upward backward movement is allowed.

  On the other hand, the engaging teeth 164 mesh with the engaging teeth 154 and function to hold and lock the engaging teeth 154 in their advanced state, that is, in the lowered state in the figure. That is, the pilot valve body 46 is held and locked in the closed position.

In this embodiment, a forced rotation ring 168 having a function of forcibly rotating the rotor 128 when the push button 126 is pushed is provided below the rotating member 114.
The forced rotation ring 168 is placed on the pedestal part 134 of the locking member 122 as shown in FIG.
The forced rotation ring 168 has a cylindrical shape as a whole, and an inward flange portion 170 is provided at the lower end thereof.

The forced rotation ring 168 is integrally provided with a plurality of claws 172 protruding upward at predetermined intervals in the circumferential direction along the upper end thereof. The upper surfaces of the claws 172 are inclined cam surfaces 174.
When a downward force is exerted on the rotor 128 by the push button 126, the cam surfaces 174 abut against the lower surface (see FIG. 14) of the protruding second engaging teeth 154 of the rotor 128. The rotor 128 is forced to rotate counterclockwise in FIG. 14 by its cam action.

  However, the rotor 128 is based on the biasing force of the coil spring 80 when its rotational resistance, that is, the sliding resistance of the rotating member 114 with respect to the upper surface of the flange portion 160 and the sliding resistance of the push button 126 with respect to the drive cam surface 150 are small. Before contacting the cam surface 174 of the forced rotation ring 168, the cam action of the drive cam surface 150 of the push button 126 and the first driven cam surface 156 of the rotor 128 contacts the cam surface 174 of the forced rotation ring 168. Rotate forward.

However, when the rotor 128 is used for a long period of time, the sliding resistance gradually increases due to wear powder generated on the sliding surface.
Therefore, even if the push button 126 is pressed downward, the rotor 128 may not rotate lightly and smoothly.
At this time, even if the rotor 128 does not rotate smoothly, when the push button 126 is pressed down strongly, the corner portion of the engaging tooth 154 of the rotor 128 hits the cam surface 174 of the forced rotation ring 168. As a result, the rotor 128 is forcibly rotated by the cam surface 174 of the forced rotation ring 168.

  In the present embodiment, when the push button 126 is rotated via the rotating sleeve 129, the rotating member 114 rotates integrally therewith, and the rotating shaft 114 is rotated by the screw feed between the female screw 116 and the male screw 112. It moves forward and backward in the left-right direction in FIG. That is, the telescopic shaft 120 expands and contracts in the left-right direction.

Specifically, when the push button 126 is rotated in the direction of decreasing the flow rate, the action shaft 104 moves forward in the left direction in FIG. 12 and the telescopic shaft 120 extends.
As a result, when the contact portion 106 of the action shaft 104 continuously changes in position in the left direction in the drawing, the one end portion 82A of the swing bar 84 is pushed by this to rotate in the left direction in the drawing, and the contact portion. In accordance with 106, the position is continuously changed to the left in the figure.

At this time, the other end portion 82B of the swing bar 84 is continuously rotated in the opposite right direction in FIG. 4 to change its position, and the pilot valve body 46 is moved forward in the right direction in FIG. , Change its position continuously.
The flow rate is continuously reduced by the continuous position change of the pilot valve body 46.

  Further, when the push button 126 is rotated in the direction of increasing the flow rate, the action shaft 104 continuously moves backward in the right direction in FIG. 12 to continuously change the position of the contact portion 106 and swings accordingly. The upper end portion 82A of the bar 84 continuously changes its position following the contact portion 106 in the right direction in the figure by the urging force of the coil spring 80.

  Along with this, the position of the other end 82B of the swing bar 84 is pushed by the coil spring 80 and continuously changes in the left direction in FIG. 46 moves backward in the left direction in FIG. 4 and continuously changes its position in the left direction to increase the flow rate.

  On the other hand, when the push button 126 is pushed in the left direction in FIG. 12, the push button moves to the push position (the state shown in FIG. 23A) and the retracted position (the state shown in FIG. 23B) for each push. At the same time, the pilot valve body 46 is switched between the valve closing position shown in FIGS. 4 and 5 and the valve opening position shown in FIG. 6 and held at the respective positions by the thrust lock mechanism 127.

15 and 16 show the operation of the thrust lock mechanism 127 that switches the position of the pilot valve body 46 between the valve closing position and the valve opening position each time the push button 126 is pushed, and holds the position at the respective positions. It is specifically shown.
FIG. 15I shows the closed state of the pilot valve body 46, that is, the water stop state. At this time, the engagement teeth 154 of the rotor 128 are engaged with the engagement teeth 164 of the guide portion 162 of the rotation sleeve 129. Therefore, the rotor 128 is held in the locked state at the lowered position in FIG. 15, that is, the forward position (left position in FIG. 12). That is, the pilot valve body 46 is held in the closed state.
At this time, the push button 126 stops at the pushing position and is held at the pushing position.

When the push button 126 is pushed to the left as shown in (II) in this state, the telescopic shaft 120 moves forward in the left direction in FIGS. 11 and 12 while maintaining a constant expansion / contraction amount, and the rotor 128 is moved. The coil spring 80 is pushed down to the left (downward in FIG. 15) against the rightward biasing force in the drawing, and the engagement teeth 154 of the rotor 128 and the engagement teeth 164 of the guide portion 162 are disengaged. .
Then, the cam action between the drive cam surface 150 of the push button 126 and the first driven cam surface 156 of the rotor 128 causes the rotor 128 to rotate a predetermined angle in the left direction in FIG. The rotation is stopped at a position (first stopper position) at which 148 and the engagement tooth 152 of the rotor 128 are just meshed with each other. FIGS. 15 (III) and 15 (A) show the state at this time.

  At this time, as shown in (III) and (B), the second driven cam surface 106 of the rotor 128 is opposed to the next guide cam surface 166 in the rotation direction of the guide portion 162, where (IV) As shown, when the pushing force applied to the rotor 128 is removed, the urging force of the coil spring 80 raises the rotor 128 together with the push button 126 and the rotating member 114 by a minute distance, and the second follower of the engaging tooth 154. The cam surface 106 contacts the guide cam surface 166 of the guide portion 162.

Then, due to the cam action of the guide cam surface 166 and the second driven cam surface 106, the rotor 128 further rotates and moves in the direction indicated by the arrow in the figure, and is engaged as shown in FIGS. 15 (V) and 15 (B). The teeth 154 reach the position of the insertion groove 146 of the guide portion 162.
Here, when the engaging teeth 154 are inserted into the insertion grooves 146, the rotor 128 is moved backward in the right direction in FIG. 23 (upward in FIG. 16) by the urging force of the coil spring 80 together with the push button 126 (FIG. 16 (upward)). VI)), the push button 126 is pulled in the right direction in FIG. 11 and held in its retracted position, and the position of the telescopic shaft 120 is switched to the retracted position in FIG. Becomes a valve open state (water discharge state), water flows in the main water channel, and water is discharged from the water discharge portion.

  When the push button 126 is pushed in again from this valve-opened state, the rotor 128 is lowered from the raised position in FIG. 16, and when the engaging teeth 154 are disengaged from the fitting groove 146, the rotor 128 is connected to the drive cam surface 150 and the first cam. 16 The cam action with the driven cam surface 156 rotates in the arrow direction (left direction) in FIG. 16 (VII), and the engagement tooth 152 of the rotor 128 is the next engagement tooth in the rotation direction of the push button 126. 148 is engaged, and the next one-pitch rotational movement of the rotor 128 is stopped there (FIG. 16 (VIII)).

In this state, when the pushing force on the push button 126 is removed, the urging force of the coil spring 80 raises the rotor 128 by a small distance from the lowest position, and the second driven cam surface 106 of the engagement tooth 154 is moved to the guide portion 162. The guide cam surface 166 is contacted (FIG. 16 (IX)), and the rotor 128 is further rotated to the left in the figure by the cam action, and the engaging teeth 154 of the rotor 128 are moved to the guide portion. A position (second stopper position) that meshes with the next engagement tooth 164 of 162 is reached, where the rotational movement of the rotor 128 is stopped (FIG. 16 (X)).
The state shown in FIG. 16 (X) is the same state as shown in FIG. 16 (I), and here, the pilot valve body 46 and the main valve body 32 are in a closed state, that is, a water stop state.

As described above, the rotation operation unit 180 is regulated to the minimum flow rate position when the upper projection 208-1 of the outer ring member 188 hits the stopper projection 236 of the push operation unit 182. 21 and 22 (II) show the state at this time.
In this state, when the push operation unit 182 is pushed downward in the figure as shown in FIG. 22 (III), the push operation unit 182 is held in the pushed position.
At this time, the stopper protrusion 236 is also lowered downward in the drawing from the position shown in FIG. 22 (II), more specifically, as shown in FIG. 22 (III), the upper protrusion 208-1 and the lower protrusion 208-2 in the protrusion 208 It will be in the state located in the same height position as the notch 214 between (refer FIG. 22 (III) (B)).

In this state, the rotation operation unit 180, specifically the outer ring member 188, can be further rotated in the counterclockwise direction.
Therefore, when the rotation operation unit 180 is rotated by a small angle in the same direction, the stopper protrusion 236 enters the notch 242 between the upper protrusion 208-1 and the lower protrusion 208-2 as shown in (III). .
Under this state, even if a pushing force is applied to the push button 126 via the push operation unit 182 (even when the push button 126 is turned on (opened)), the stopper protrusion 236 and the upper protrusion 208-1 are brought into contact with each other. The push operation unit 182 and the push button 126 cannot be moved upward, and therefore the push button 126 is held in the push-in position, that is, the water stop position via the push operation unit 182, and is locked there.
In addition, as shown in FIG. 22 (III), the rotation operation unit 180 is prevented from further rotation by the projection 208 coming into contact with the circumferential end of the arc-shaped rising portion 226 of the base portion 130.

As shown in FIG. 20, the push operation portion 182 is provided with a circular pressing portion 284 protruding downward on the lower surface of the upper wall 230.
When a force downward in FIG. 20 and left in FIG. 17 is applied, the push operating portion 182 pushes the push button 126 left in FIG. 17 with this pressing portion 284, so that the pilot valve is configured integrally with the valve shaft 66. The body 46 is moved to the right.
The pushed push operation unit 182 is held in the pushed position.

The above operation device 7 performs the following movement as a whole.
FIG. 22I shows a state where the rotation operation unit 180 is rotated to the maximum flow rate. In this state, water is circulated through the main water channel at the maximum flow rate while the push button 126 is opened via the push operation unit 182.
When the rotation operation unit 180 is rotated counterclockwise in the figure from this state, the projection 208 of the outer ring member 188 that rotates together with the rotation operation unit 180 at the minimum flow rate position shown in FIG. The projection 208-1 comes into contact with the stopper projection 236 of the push operation unit 182, and further rotation is temporarily prevented.
If the push operation unit 182 is pushed in and held in this state in this state, further slight rotation of the rotation operation unit 180 is permitted at this point.
Therefore, when the rotation operation unit 180 is further rotated counterclockwise, the projection 208 of the outer ring member 188 comes into contact with the circumferential end of the rising portion 226 of the base portion 130 when further rotated, and further rotation there. Be blocked.

In this state, the stopper projection 236 of the push operation unit 182 in the push-in position enters the notch 214 between the upper projection 208-1 and the lower projection 208-2 of the outer ring member 188, and the shaft The movement is prohibited in the direction, that is, the vertical direction of FIGS. 22 (III) and 22 (B).
That is, here, the push button 126 is locked via the push operation unit 182. Therefore, even if a pushing force is applied to the push button 126 via the push operation unit 182 in this state, the push button 126 does not move up and therefore water discharge based on the rise of the push button 126 and the push operation unit 182 is not performed. .

In the present embodiment, the valve device 10 is provided separately from the operation device 7 and is connected by the transmission mechanism 12, so that the degree of freedom in layout when installing the faucet device 6 is increased. Can be increased.
In addition, the valve device 10 does not have to be installed at the place where the operating device 7 is installed, and the valve device 10 can be provided at a different location and in a concealed state. The beauty and design around the installation location, that is, around the installation location of the faucet device 6 can be enhanced.

In this embodiment, since the operating force applied to the operating device 7 is transmitted to the valve device 10 via the swing bar 84, the operating force is applied by the engagement of the pinion gear and the rack gear as the transmission mechanism 12. Compared with the transmission type, the transmission efficiency of the operation force to the valve device 10 is high, and therefore the valve device 10 can be operated with a small operation load, and the operation device 7 can be configured to be thin.
Further, in the transmission mechanism 12 having the swing bar 84, the required number of parts can be minimized, the number of parts of the faucet device 6 can be reduced, and the cost of the faucet device 6 can be reduced. it can.

  As described above, in this embodiment, the rotation operation of the rotation operation unit 180 causes the contact portion (action) of the action shaft 104 to the one end portion 82A of the swing bar 84 on the operation device 7 side by an amount corresponding to the rotation operation amount. Point) is linearly moved, and the swing bar 84 is continuously rotated around the shaft 82 by an amount corresponding to the rotational operation amount of the rotary operation unit 180, and the pilot is moved at the other end 82B of the swing bar 84. The valve body 46 is moved forward and continuously in a linear manner so as to perform a flow control operation.

  That is, in this embodiment, the rotational motion of the rotary operation unit 180 is once converted into the linear motion of the abutting portion 106 of the drive mechanism 102 and then converted into the rotational motion of the swing bar 84, thereby The moving bar 84 is slightly rotated, specifically, the position of the swing bar 84 around the shaft 82 of the other end 82B is slightly changed, and the pilot valve body 46 is fluidly operated. .

Therefore, in this embodiment, even when the rotation operation unit 180 is largely rotated, even when the operation force input unit is largely rotated, the linear movement amount (distance) of the contact portion 106 of the drive mechanism 102 is reduced. Can easily be reduced.
As a result, the rotational angle position of the swing bar 84 around the shaft 82 can be minutely changed, and accordingly, the position of the pilot valve body 46 can be delicately changed accordingly.
Therefore, according to the water faucet device 6 of this embodiment, the water discharge flow rate is delicately determined based on the rotation operation of the rotation operation unit 180 even though the pilot valve body 46 is operated via the swing bar 84. Can be changed and adjusted.

  In particular, in the present embodiment, since the operation shaft 104 is linearly moved back and forth by screw feed by the rotation of the rotation member 114 based on the rotation operation of the rotation operation unit 180, the rotation operation unit 180 is greatly rotated. Even in this case, the action shaft 104 can be linearly moved by a small amount (distance) according to the operation amount, thereby slightly changing the position of each end of the swing bar 84 and accompanying this, the pilot The flow adjustment operation can be performed by slightly changing the position of the valve body 46.

  Furthermore, according to the present embodiment, both the operations applied to the rotation operation unit 180 and the push operation unit 182 can be transmitted from the action shaft 104 to the pilot valve body 46 via the swing bar 84. The pilot valve body 46 can be flow-controlled and discharged.

In addition, since the thrust lock mechanism 127 is provided, when the water discharge and the water stop are switched by the operation of the push operation unit 182, the water discharge state and the water stop state are maintained as they are by the thrust lock mechanism 127 thereafter. Can do.
Further, since the thrust lock mechanism 127 is provided on the side of the operation device 7, the switching feeling by the thrust lock mechanism 127 is directly transmitted to the hand, and the user can directly feel that the switching operation has been performed. Can feel a good operation feeling.

In the present embodiment, the coil spring 80 is provided on the valve device 10 side so as to urge the pilot valve body 46 in the backward direction and the valve opening direction, and the coil spring 80 is used as a spring for operating the thrust lock mechanism 127. We are using.
Therefore, it is not necessary to separately provide a spring for returning the pilot valve body 46 in the direction opposite to the operation direction by the operating device and a spring for operating the thrust lock mechanism 127, and the number of necessary springs can be reduced. it can.

In the present invention, the valve device 10 is configured as a pilot type valve device, and the transmission mechanism 12 is connected to the pilot valve body 46 to transmit the operating force to the pilot valve body 46. The operation force can be further reduced, and further light operation can be realized.
Further, the strength of the member that transmits the operating force can be reduced, and the required cost can be reduced.

  In the present embodiment, the valve device 10 is housed inside the basin table 5 that protrudes indoors from the wall W of the bathroom, and the operation device 7 projects from the wall W to the indoor side above the basin table 5. Provided in the upper counter section 3, the upper operating device 7 and the lower valve device 10 are connected by a transmission mechanism 12.

  By doing in this way, compared with the case where the faucet device having the valve device 10 and the operation device 7 is installed in the upper counter portion, the upper counter portion 3 on the installation side of the operation device 7 that appears on the appearance is compactly configured. It is possible to improve the aesthetics and design of the installation part of the faucet device 6.

Here, detailed description thereof will be omitted, and only the reference numerals corresponding to the corresponding parts are shown.
However, the hot water main valve body 338 and the water side main valve body 340 are provided in opposite directions in the drawing. That is, the hot water main valve body 338 moves forward in the right direction in the drawing toward the hot water main valve seat 342, and the water side main valve body 340 moves in the left direction in the drawing toward the water side main valve seat 344. To do.

That is, the hot water main valve body 338 moves back and forth in the left-right direction in the drawing with respect to the hot water main valve seat 342 to change the valve opening.
Specifically, the hot water main valve body 338 is closed by being seated on the hot water main valve seat 342, and is opened by moving away from the hot water main valve seat 342 in the left direction in the figure. The amount of hot water flowing into the mixing chamber 330 is changed in accordance with the change of.

On the other hand, the water-side main valve body 340 moves back and forth in the left-right direction in the figure with respect to the water-side main valve seat 344, and changes the valve opening.
More specifically, the valve is closed by being seated on the water-side main valve seat 344, and is opened by moving away from the water-side main valve seat 344 in the right direction in the drawing, and the mixing chamber is changed according to the change in the valve opening amount. The amount of water flowing into 330 is changed.
However, in this valve device 10, the hot water side main valve body 338 and the water side main valve body 340 change the valve opening amount in a reverse relationship, and increase or decrease the inflow amount of hot water and water in a reverse relationship. Change.

  The hot water side back pressure chamber 346 causes the internal pressure to act on the hot water main valve body 338 as a pressing force in the valve closing direction in the right direction in the figure, and the water side back pressure chamber 348 The side main valve body 340 is caused to act as a pressing force in the valve closing direction in the left direction in the figure.

The hot water side pilot valve body 350 and the water side pilot valve body 352 also move forward and backward in the left-right direction in the figure in a reverse relationship.
That is, the hot water side pilot valve body 350 moves forward in the right direction in the drawing to finally close the valve, and moves backward to the left to open the valve.
On the other hand, the water-side pilot valve body 352 moves forward in the left direction in the figure to finally close the valve, and moves backward in the right direction in the figure to open the valve.
However, in this embodiment, the hot water side pilot valve body 350 and the water side pilot valve body 352 are configured integrally with a common valve shaft (temperature control shaft) 66.

In this valve device 10, as shown in FIG. 27, both the hot water side main valve body 338 and the water side main valve body 340 are opened, and the hot water side pilot valve body 350 is moved in the right direction in the figure. When moving forward, the hot water side main valve body 338 moves forward in the same right direction following the hot water side pilot valve body 350 while maintaining a constant minute follow-up gap with the hot water side pilot valve body 350, reducing the gap S _H between the hot-side main valve seat 342, continuously decreasing change the inflow of hot water into the mixing chamber 330.

At this time, the water-side main valve body 340 retains a constant minute follow-up gap with the water-side pilot valve body 352 by the backward movement of the water-side pilot valve body 352 in the right direction in the drawing, moves backward to the right to follow the backward movement of the right in the drawing direction of the valve body 352, a gap S _C between the water-side main valve seat 344 is continuously increased, the inflow of water into the mixing chamber 330 Increase the amount.
And by these, the ratio of the water inflow amount with respect to the hot water inflow amount is continuously increased and changed, and the mixed water temperature is continuously decreased.

Conversely, when the hot water side pilot valve body 350 moves backward in the left direction in the figure, the hot water side main valve body 338 follows this, and moves backward in the left direction in the figure, as shown in FIG. 27 (II). in the gap S _H between the hot-side main valve seat 342 is continuously increased, continuously increasing change the inflow of hot water into the mixing chamber 330.

At this time, the water side pilot valve body 352 moves forward in the left direction in the figure, and accordingly, the water side main valve body 340 follows the water side pilot valve body 352 and moves in the left direction in the figure, the gap S _C between the water-side main valve seat 344 continuously decreases continuously decreasing change the inflow of water into the mixing chamber 330.
As a result, the temperature of the mixed water rises continuously, and the mixed water whose temperature has risen flows out from the outlet 334.

As shown in FIG. 24, the swing bar 84 in the transmission mechanism 12 is connected to the valve shaft 66 via the advance / retreat rod 70 and the spherical bearing 74.
Moreover, in this embodiment, the rotation operation part 180 of the said 1st Embodiment of FIGS. 1-23 adjusts the valve opening amount of the hot water side pilot valve body 350 and the hot water side main valve body 338 (that is, it is). Is configured as a temperature adjustment operation unit that adjusts the mixing ratio of hot water, that is, the temperature of the mixed water (by adjusting the position of the mixing valve 358), and the push operation unit 182 in the first embodiment includes The side main valve body 338 is configured as an opening / closing operation unit (that is, a switching operation unit between mixed water discharge and water discharge).

In this embodiment, when the rotary operation unit 180 is rotated, the operating force is transmitted to the valve shaft 66 via the transmission mechanism 12, and the valve shaft 66 is moved back and forth in the left-right direction in the drawing.
That is, the hot water side pilot valve body 350 and the water side pilot valve body 352 integrally formed therewith are continuously moved forward and backward in an opposite relationship.
As a result, the hot water side main valve body 338 and the water side main valve body 340 change the valve opening amount in a reverse relationship, and the mixed water temperature is continuously changed in level.
Even in this embodiment, the rotation operation unit 180 is restricted so that the hot water main valve body 338 is not closed by the rotation operation of the rotation operation unit 180.

On the other hand, every time the push operation unit 182 is pushed, that is, pushed, the hot water pilot valve body 350 and the hot water main valve body 338 are opened as shown in FIG. 26, and closed as shown in FIGS. And the respective positions are held by the thrust lock mechanism 172.
That is, the valve device 10 switches between a water discharge state in which only water is discharged and a mixed water discharge state in which mixed water is discharged.
Thus, when switching to the mixed water discharge state, the hot water main valve body 338 and the water main valve body 340 are opened with the previously adjusted valve opening amount, and the mixed water is set at the previously set mixed water temperature. Spill.

  Although this example is an example of a so-called mixing type hot and cold water mixing valve device, the present invention has a temperature-sensitive spring that changes the urging force according to the change of the mixed water temperature, and the mixed water temperature is automatically set to the set temperature. It can also be applied to a hot and cold water mixing valve device with an automatic temperature control function.

Although the embodiment of the present invention has been described in detail above, this is merely an example.
