In the conventional single lever mixer tap described above, the valve element is composed of two disks, a fixed disk and a movable disk. / Purification of water is switched and the flow rate is adjusted by moving the movable disk back and forth by the vertical rotation of the operation lever. With the horizontal rotation of the operation lever, only the raw water Switching from the raw water discharge to the purified water discharge is performed continuously with the discharge.

[0003]

Generally, in a mixing tap, discharge using only raw water is more frequently used than discharge using only hot water, but as described above, a conventional single-lever mixing tap is used. Since the switching from the raw water discharge to the purified water discharge is performed continuously to the discharge of the raw water only, the position of the operation lever in which only the raw water discharge is performed In any position ,
It was difficult to tell if it was only water discharge, and there was a problem in terms of usability. The present invention has been made in view of the above-mentioned problems of the prior art, and its purpose is to limit the boundary position between the raw water discharge and the clean water discharge within the rotation range of the operation lever, in other words, only the raw water. Is to be able to clearly recognize the discharge position.

[0004]

In order to solve the above-mentioned object, the single-lever mixer tap according to the present invention is connected to two raw water system inflow passages for hot water and water, a discharge passage, and an inlet of a water purifier. A source for connecting one or both of the raw water system inflow passages to the discharge flow passage by a horizontal rotation operation of an operation lever, and a discharge passage for water purification, a purification water introduction passage connected to the discharge flow passage and connected to an outlet of the water purifier. an aqueous discharge passage, the single lever mixer tap comprising a valve element to selectively configure the water treatment system discharge path allowed to communicate with only the water inflow passage of the raw water systems and water purification delivery path, raw water system discharge passage arrangement of the operating lever A rotation restricting means for restricting the rotation from the side to the water purification system discharge path configuration side at a discharge position of only water in the raw water discharge, and a restriction release operation means for releasing the restriction of the rotation restriction means. is there. In addition, the single lever mixing tap may be provided with a regulation release holding means for holding the rotation restricting means in a regulation released state.

[0005]

In the single-lever mixer tap constructed as described above, the rotation range of the operation lever in the horizontal direction is usually restricted by the rotation on the raw water discharge path configuration side, and the rotation to the water side is normally performed. The movement is stopped at the water-only discharge position, but the restriction release state is released by operating the restriction release operation means, and the operation lever moves beyond the water-only discharge position to the water purification system discharge path configuration side. It is possible to switch from raw water discharge to clean water discharge. Further, if the regulation release holding means is provided, when the raw water and the purified water are frequently switched and discharged in a short time, the rotation restriction means is used to hold the rotation restriction means in the regulation release state. The two discharge modes can be continuously switched without performing the operation of releasing the movement restricting means.

The center of the base B2 is fixed to the upper end of the operation lever 22, and its horizontal and vertical directions are provided. Is transmitted to the movable desk 15 via the valve guide 18 or the operating lever 22.

A pin guide hole 24 is formed in the lower surface of the base B2 of the operation lever B at an eccentric position. The hole 24 serves as a component of the rotation restricting means D together with the stopper 21 of the stopper ring 20. A stopper pin 25 is inserted to be able to move up and down and urged forward by a spring 26.
Projecting from 24 extends into the stopper ring 20. The stopper pin 25 is located at a position having a distance from the axis of the main body A that is larger than the radius of the stopper portion 21 on the inner periphery of the stopper ring 20 and slightly smaller than the radius of the portion excluding the stopper portion 21. The stopper pin 25 hits the stopper portion 21 of the stopper ring 20 at a predetermined rotation angle position with respect to the horizontal rotation of the operation lever B to the left, and restricts further rotation of the operation lever B to the left. Stopper part 21 of this stopper ring 20
The rotation restricting position of the operation lever B against the left rotation of the operation lever B by the stopper pin 25 is such that the passage 14 of the movable disk 15 is perfectly aligned with the water valve port 10 of the fixed disk 13 as shown in FIG. A position where only the valve port 10 communicates with the outlet port 11, and a position where the raw water system water side can be fully opened by turning the operation lever B vertically in this position (hereinafter referred to as a water side fully open discharge position). Is set to

On the other hand, one end of a wire 27 such as a piano wire is connected to the rear end of the stopper pin 25, and the other end of the wire 27 is inserted through a through hole 28 formed in the lever B1 so that the lever B
1 is communicated with the regulation release operation means E provided on the lower surface of the intermediate portion.

The restriction releasing operation means E comprises a push button 30 and a slider 31 which are connected to the through hole 28 so as to be able to protrude and retract in a button mounting concave hole 29 formed on the lower surface of the lever portion B1 and are undetachable. The push button 30 is normally lowered by the urging force of the spring 26 and is projected from the lower surface of the lever portion B1. Push button 30 has a slider housing portion 30b formed in the guide surface 30a which is inclined to the front side of the notched portion upward forward notched toward the rear from the upper surface in the state attached to the lever portion B1, the housing Part 30
The slider 31 is stored and deployed in b.

The slider 31 has a guide surface 30 for the push button 30.
The taper surface 31a is formed in the shape of a substantially right triangle having a taper surface 31a corresponding to the taper surface a, and the taper surface 31a is slidably brought into contact with the guide surface 30a and stored in the slider storage portion 30b of the push button 30.

Wire guide holes 32 are formed in the guide surface 30a of the push button 30 and the taper surface 31a of the slider 31 so as to be drawn out from the through holes 28 formed in the lever portion B1. The inserted wire 27 is fixedly attached to a shaft pin 33 mounted on the side wall of the slider 31.

Therefore, the restriction releasing operation means E is normally pulled forward by the slider 31 via the wire 27 by the force of the spring 26 for urging the stopper pin 25 in the forward direction, and the guide surface 30a of the push button 30 is In front position. When the push button 30 is pushed in this state, the push button
As the slider 30 moves upward, the slider 31 moves to the guide surface 30a.
Move backwards along. When the slider 31 moves rearward, the stopper pin 25 is pulled by the wire 27, is pulled upward, and retreats. Also, push button 30
When the pushing force is released, the stopper pin 25 is pushed down again by the force of the spring 26, and the wire
Since 27 pulls the slider 31, the slider 31 slides along the guide surface 30a of the push button 30 and returns to the original front position.

When the stopper pin 25 is pulled upward, since the pin 25 is pressed against the stopper portion 21, the resistance against the pulling is large and the movement is heavy. The roller pin 34 is provided such that its roller surface is exposed to the pin contact surface of the stopper 21.

In the single-lever mixer tap of this embodiment, when the operating lever B is rotated to the left to a certain position and reaches the water-side fully open discharge position in the raw water discharge, the stopper pin 25 is turned on. The rotation restricting means D contacts the stopper portion 21 of the stopper ring 20, and the operation lever B
Can no longer rotate to the left side, the user is the water side fully open discharge position in the raw water system discharge,
If it is rotated further to the left, it can be recognized that switching to discharge of the water purification system is performed.

When the water is to be further rotated to the left to discharge the purified water, the push button 30 of the restriction releasing operation means E is pushed in, and the slider 31 is retracted, and the stopper pin 25 is moved through the wire 27. Is lifted upward from the stopper ring 20, and the engagement of the pin 25 with the stopper portion 21 is disengaged, so that the rotation restriction by the rotation restriction means D is released, and the operation lever B can be further rotated to the left. As shown in FIG.
Can be moved to a position where the water valve port 10 and the water purification valve port 12 communicate with each other.

Thus, the single-lever mixer tap converts the raw water supplied from the water supply source into the water inflow passage 2 of the main body.
The water is then sent out to the water purifier G via the water valve port 10, the passage 14, the water purification valve port 12, and the water purifying delivery path 6, and after being purified by the water purifier G, is again introduced into the main body A. Water can be discharged from the discharge port 3 through the discharge flow path 4 as purified water.

Next, a second embodiment shown in FIGS. 10 to 12 uses a wire rod as a means for remotely operating the stopper pin 125.
27, a thin plate 135 having one end connected to a stopper pin 125 is inserted through a through hole 128 formed in the lever portion B1 of the operating lever B, and a button mounting recess 12 is formed.
It extends 9, to form a taper surface 135a of the end corresponding to the button 130 pushed bent triangle, the taper surface 135a portion and the push button 130 constitutes the regulation release operation means E . In the case of this embodiment, a concave hole 129 for mounting a button is formed so as to open on the upper surface of the lever portion B1, and the button 130 is mounted so as to be pushed into the concave hole 129 from top to bottom. The taper surface 135a is formed so as to be inclined upward toward the base side of the lever portion B1.

The rotation restricting means D is provided on the center line of the stopper ring 120 so that the stopper pin 125 penetrates the operating lever 122 so as to cross the operating lever 122 in the axial direction thereof. With the rotation of the operating lever accompanying the rotation of, the both ends thereof are brought into sliding contact with the inner peripheral surface of the stopper ring 120 to be rotated horizontally.

The stopper ring 120 is a valve guide.
118 Cover A1 placed above and mounted on top of body A
Is fixed by a spline so that it cannot rotate, and has an inwardly projecting flange 120a at the upper end thereof.
The stopper pin 125 is slidably pressed from below by a spring 126 against 120a. A stopper portion 121 is formed on the lower surface of the flange 120a of the stopper ring 120 at a predetermined position in the circumferential direction so as to protrude downward. on the other hand,
The thin plate 135 is connected through the operating lever 122 to a position where the thin plate 135 is deflected to the end that collides with the stopper portion 121 by rotating the stopper pin 125 to the left. The through-hole 137 formed in the operating lever 122 to allow the stopper pin 125 to pass therethrough is provided in the stopper pin 125 by the tilting of the operating lever 122 accompanying the vertical rotation of the operating lever B.
Has a run-out so as not to affect the horizontal position of the vehicle.

In this embodiment, the rotation of the operation lever B of the mixer tap to the left is usually at the position where the stopper pin 125 interlocked with the rotation of the operation lever B collides with the stopper portion 121 (raw water system). The rotation is once restricted at the fully open discharge side on the water side during discharge, but when the button 130 is pressed in, the stopper portion 121 of the stopper pin 125 is moved through the thin plate 135.
The collision side is pushed down from the lower end of the stopper portion 121, so that the collision between them is avoided, and the operation lever B can be further rotated to the left. That is, it is possible to switch to discharge of the water purification system.

The concave and convex portions indicated by reference numeral 138 in FIG. 10 are flow rate recognizing means for allowing the user to recognize the flow rate by adjusting the flow rate when the flow rate is large, medium, small or click. A click feeling can be obtained by engaging and disengaging the concave portion and the convex portion with the rotation operation in the vertical direction.

Next, a third embodiment shown in FIGS. 13 to 17 differs from the above two embodiments in that the spatter pins 25 and 125 are remotely operated using the wire 27 and the thin plate 135.
The stopper pin 225 can escape from the stopper portion 221 directly by operating a button.

That is, in this embodiment, the rotation of the operation lever 222 accompanying the rotation of the operation lever B is placed above the cartridge retainer 219 provided on the cartridge case 217 that houses the valve element C and the like. And a stopper pin 225 is provided so that the stopper pin 225 stands up through the desk 239 slidably up and down so that the lower end thereof is in contact with the peripheral edge of the upper surface of the cartridge retainer 219. The pin 225 rotates along the peripheral edge of the upper surface of the cartridge retainer 219, and the peripheral edge of the upper surface of the cartridge retainer 219 includes:
A stopper pin when the operation lever B is rotated to the left by a predetermined angle and the movable disk 15 is rotated and slid to a position where only water can be discharged in a fully open state in raw water discharge.
A stopper portion 221 is provided at a portion corresponding to the position 225. The stopper portion 221 has a stopper pin 225 for rotating the operation lever B from the hot water side discharge position to the water side fully open discharge position in the raw water discharge system. It is formed to be one step higher than the moving part via the inclined surface 240.

The operation lever B has a button hole 241 formed in a base B2 thereof, that is, a portion covering the upper end opening of the main body A, and a cylindrical push button 230 having a lower surface opened in the button hole 241. The spring 226 is urged upward by a spring 226 so as to be freely retractable and non-rotatably mounted. Push button 230 above
An acme screw 242 is cut on the inner peripheral surface.
A rod shaft 243 is screwed and connected to this button 230 via 2.
A semicircular lock desk 244 provided at the lower end of the rod shaft 243 corresponds to the head of the stopper pin 225 with a slight gap.

Therefore, in this embodiment, when the operating lever B is rotated to the left, that is, the water side, and reaches the water side fully open discharge position, the peripheral edge of the upper surface of the cartridge holder 219 is moved with the rotation of the operating lever B. Stopper pin 22
5 try to move further while rising along the inclined surface 240 of the stop part 221.However, as shown in FIGS. 14 and 15, the head is pressed by the lock desk 244, so that further movement is not possible. Therefore, the operation lever B cannot be further rotated, and stops at that position. That is, the operation of rotating the raw water system further to the left cannot be performed, the discharge of the raw water system is fixed to the fully open state on the water side, and the careless switching to the discharge of the purified water system is prevented.
As described above, in this embodiment, the stopper pin 225, the turn desk 239, the stopper portion 221 on the cartridge holder 219, and the lock desk 244 constitute the rotation restricting means D.

However, when the push button 230 is pushed in this state, the lock desk is rotated by the acme screw 242 via the rod shaft 243 as shown in FIGS. 16 and 17, and comes off the head of the stopper pin 225. Since the pin 225 can be moved upward and the locked state is released, if the operating lever B is further rotated to the left while pressing the push button 230, the stopper pin 225 moves the stopper portion 221 to the inclined surface 240. The operation lever B moves upward, and the operation lever B is not restricted by the rotation operation toward the water purification system discharge side. Therefore, switching to the water purification system discharge is also possible. That is, the push button 230 and the rod shaft 243 connected to the push button 230 via the acme screw are connected to the regulation release operation means E.
Is composed.

Next, in a fourth embodiment shown in FIGS. 18 to 22, the remote control means is not used similarly to the third embodiment, and the restriction releasing operation means E is provided near the installation position of the stopper portion 321. In the same manner as in the third embodiment, the regulation release operation means E
The push button 330 provided on the base B1 of the operating lever B is pushed in, and the push button 330 is
The rotation restriction is released by rotating the semi-circular lock desk 344 provided at the lower end of the rod shaft 343 which is connected through the lock shaft 343. However, the lock desk 344 directly hits the stopper 321 to restrict the rotation of the operation lever B. The third embodiment differs from the third embodiment in the structure.

That is, in this embodiment, the lock desk 344 is provided at the lower end of the rod shaft 343 such that the semicircular linear portion intersects the movement locus of the rod shaft 343 by the rotation operation of the operation lever B. On the other hand, the corresponding stopper portion 321 is provided on the upper surface of the stopper ring 320 provided above the valve guide 318, and the rod shaft 343 is provided on the stopper ring 320.
The operation lever B is formed so as to be in contact with the lock desk 344 when the operation lever B is rotated leftward to the water side fully open discharge position in the raw water discharge system.

Therefore, when the operating lever B is rotated leftward, the lock desk 344 is moved to the stopper portion 321 at the water side fully open discharge position in the raw water discharge as shown in FIGS.
The rotation of the operation lever B is restricted at that position, and the rotation cannot be further performed, and the operation lever B is at the water side fully open discharge position. As a result, careless switching to the water purification system discharge is prevented. The switching from the raw water discharge to the clean water discharge can be performed by pressing the push button 330 when the rotation of the operation lever B is restricted, as shown in FIGS. 21 and 22.
342 causes the lock desk 344 to rotate through the rod shaft 343, and the linear portion thereof goes around the outer periphery of the stopper portion 321.
Since the collision state with the stopper portion 321 is released and the rotation of the operation lever B is no longer restricted, the operation lever B is further rotated to the left to move to the switching position.

Next, a fifth embodiment shown in FIGS. 23 to 25 will be described. In this embodiment, the rotation restricting means D for restricting the rotation of the operation lever B to the fully open discharge position on the water side in the raw water discharge can be fixed in a state where the restriction is released. The stopper 421 is attached to the inner peripheral surface of the stopper ring 420
The stopper pin 425 is urged in the pin guide hole 424 formed in the lower surface of the base B2 of the operation lever B by the spring 426 in the depth direction of the hole 424, that is, in the retreating direction. A flexible and axially rigid wire 427, for example, one end of a piano wire, is connected to the rear end of the stopper pin 425 of the rotation restricting means D which is provided so as to be able to move forward and backward. The other end of the lever 427 is inserted through a through hole 428 formed in the lever B1 to communicate with a restriction releasing means E provided on the lower surface of the intermediate portion of the lever B1 via a lock mechanism F.

The stopper pin 425 is protruded from the pin guide hole 424 against the urging force of the spring 426 and protrudes into the stopper ring 420, so that the stopper pin 425 is fixed with respect to the rotation of the operation lever B to the left in the horizontal direction. At the rotation angle position, the stopper lever 421 of the stopper ring 420 hits the stopper portion 421 so that the further rotation of the operation lever B to the left can be restricted. The horizontal movement of the operation lever B by the stopper portion 421 and the stopper pin 425 is possible. The rotation restriction position for the rotation to the left in the direction is set to a predetermined angular position where the rotation position of the movable disk 13 rotated by the operation lever B becomes the water side fully open discharge position in raw water discharge.

The restriction releasing operation means E is connected to the through hole 428 and has a button mounting recess 429 recessed on the lower surface of the lever portion B1.
A push button 430 that can be freely moved in and out of the
Similarly, the push button 430 is provided with a slider 431 housed in the concave hole 429, and the push button 430 usually falls downward by its own weight and projects from the lower surface of the lever portion B1.

The push button 430 has a slider engaging concave portion 445 which is opened on the upper surface when mounted on the lever portion B 1, and the concave portion 445 is engaged with the slider 431. Slider 431 is recessed at the back of push button 430
The lever 429 is provided so as to be able to advance and retreat in the axial direction of the lever portion B1 and is engaged with the slider engaging concave portion 445 of the push button 430. The operating shaft 447 connected to the fixing ring 446 of the lock mechanism F is operated from the side thereof. The lever protrudes toward the lever base B2. Slider engagement recess 445 and slider 43
1 slidably contacts each other and guides the slider 431 by the pushing operation of the push button 430 so that the base B2 of the operating lever B
A tapered guide surface 445a that slides to the side is formed. Further, an operation shaft insertion portion 448 through which the operation shaft 447 of the slider 431 is inserted is cut out on the peripheral surface of the push button 430.

The lock mechanism F has a through hole 428 of the lever portion B1.
The guide sleeve 449 fits into the part that connects to the button mounting recess 429, the fixing ring 446 that is connected and fixed to the operation shaft 447 of the slider 431 and is inserted into the guide sleeve 449, and faces the fixing ring 446. Guide sleeve 4
The end of the wire 427 is pressed against the rotating ring 450 by a spring 426 and pressed against the rotating ring 450 in a slip shape.

The tip of the fixing ring 446 has a sawtooth tooth 44
6a is formed, and a protrusion 446b is formed on the side peripheral surface. On the surface of the rotating ring 450 facing the fixed ring 446, serrated teeth 450a that match the serrated teeth 446a of the fixed ring 446 are formed, and on the side peripheral surface, a convex portion 450b is formed. A groove 449a is formed on the inner peripheral surface of the guide sleeve 449 so that the respective convex portions 446b and 450b of the fixed ring 446 and the rotating ring 450 are engaged.
And sawtooth-shaped steps 449b are formed alternately in the circumferential direction.

In the lock mechanism F, as shown in FIG. 23, usually, the rotating ring 450 has its convex portion 450b connected to the guide sleeve 449.
In the forward position with the saw-toothed step 449b
427 pushes the stopper pin 425 out of the hole 424 against the biasing force of the spring 426 in the retreating direction, and the stopper 421
The projection is projected into the stopper ring 420 so as to be able to collide.

When the push button 430 is pushed in from this state, the slider 431 moves forward along the guide surface of the push button 430 by sliding of the slider 431 and the guide surface of the push button 430. To move forward and move the rotating ring 450 to the guide sleeve.
Push away from serrated step 449b of 449. As a result, the rotating ring 450 rotates slightly, with its serrated teeth 450a meshing with the serrated teeth 446a of the fixed ring 446, so that the convex portion 450b corresponds to the groove 449a of the guide sleeve 449.

Thus, when the user releases the push button 430 and stops pushing the push button 430, the rotating ring 45
In FIG. 25, the convex portion 450b fits into the groove 449a of the guide sleeve 449, and is guided by the groove 449a by the urging force of the spring 426 via the wire 427, and retreats to the state shown in FIG. . Therefore, the stopper pin 425 is retracted by the force of the spring 426, and the stopper 421
Is lifted above the stopper ring 420 so as not to collide with the stopper ring 420.

Next, when the push button 430 is pressed again, the slider 431 advances to advance the fixing ring 446 to push the rotating ring 450 forward, thereby removing the projection 450b from the groove 449a of the guide sleeve 449. At this time, the rotating ring 450 rotates slightly with the serrated teeth 450a meshing with the serrated teeth 446a of the fixing ring 446, and the convex part 450b becomes the stepped part of the guide sleeve 449.
When the pressing of the push button 430 is stopped, the rotating ring 450 again engages the convex portion 450b with the serrated step portion 449b of the guide sleeve 449, as shown in FIG.
And the wire 427 is fixed to the forward
Stopper pin 425 against the urging force in the backward direction due to
Is pushed out of the hole and held in a state of protruding into the stopper ring 420. That is, the lock mechanism F is a push button
The stopper pin 425 is fixed to the restriction position and the restriction release position each time the 430 is pushed.

Thus, in the single-lever mixer tap of this embodiment, the push button 430 is pushed in so that
If the stopper pin 425 is fixed at the regulation position, when the operation lever B is rotated to the left in the horizontal direction to make the raw water discharge only water, when the stopper pin 425 is rotated to a predetermined position, the stopper pin 425 stops the stopper ring 420. Part 421
In this case, the operating lever B cannot be rotated further to the left, and it is known that the position of the operating lever B is the water-side fully open discharge position, and inadvertent switching to water purification is prevented.

When the discharge of purified water is necessary, the push button 430 is pushed in to operate the stopper pin 425.

It consists of a bridge-shaped connecting portion 552b integrally connected at the upper end, and the diameter of a circle formed by a line extending the curve of the vertical surface of the upright wall portions 552a and connecting the both is the inner diameter of the button receiver 551. It is formed so as to be substantially equal, and is fitted and fixed in the button receiver 551 so that the connecting portion 552b is upward when mounted on the operation lever B, and at a position opposed to the connecting portion 552b across the center thereof. An opening 552c formed in a slit shape extending over both upper and lower ends corresponds to the wire introduction hole 554 of the button receiver 551.

A button-engaging recess 555 is formed in the opposite vertical plane of the upright wall portion 552a in a relative manner, and is formed on one side of the recess 555, specifically, on the slit-shaped opening 552c side. Recess 555 Lock step one step higher than bottom
556 are formed. In the vertical plane of the upright wall portion 552a, a guide groove 557 extending vertically from the upper end to the same height position as the bottom surface of the button engagement recess 555 is formed to intersect with the locking step portion 556. On the other hand, the connecting portion 55
A groove-shaped slider guide 558 is formed in the center of the upper surface of the groove 2b so as to face the same direction as the slit-shaped opening 552c.

In the button cover 552, a push button 530 is housed and arranged by engaging with the button engaging recess 555, and the rolling shaft 553 is vertically movable and rotatable by engaging both ends with the guide groove 557. And a slider 531 is provided by engaging with a slider guide 558.

The push button 530 is formed in a box shape having a lateral width substantially equivalent to the width between the upright wall portions 552a of the button cover 552, and engagement projections 559 are formed on both side surfaces thereof. The protrusion 559 is engaged with the button engaging recess 555 of the button cover 552 and is housed so as to be movable up and down and back and forth between the upright wall portions 552a of the button cover 552, and the lower part thereof is below the button cover 552 and the button receiver 551. Project to The push button 530 has an open upper surface.

The rolling shaft 553 is positioned above the push button 530 and is mounted between the gad grooves 557, and is lowered by its own weight to ride on the button.

The slider 531 has a flat rectangular substrate portion 531a having the same width as the width of the slider guide 558 of the button cover 552, and a hanging portion integrally formed on the lower surface of the substrate portion 531a except for both longitudinal ends. 531b, the board part 53
The rear end of 1a is slidably engaged with the slider guide 558 back and forth, and the hanging portion 531b is inserted into the opening of the push button 530. The hanging portion 531b has a tapered surface with a front surface inclined upward and forward and a rear surface formed with a vertical surface.

As described above, in this embodiment, it is not possible to fix the state of the restriction release only by the operation of pushing the push button 530 as in the fifth embodiment. Although a sliding operation is required, the state of the push button 530 has an advantage that it can be immediately recognized whether the state is the regulation state or the regulation release state. In this embodiment, the wire 527 does not require rigidity in the axial direction.

Next, a description will be given of a seventh embodiment shown in FIGS. The seventh embodiment is different from the fifth and sixth embodiments in that the slider 531 is slid by the pushing operation of the push button 530, and the stopper pin 525 of the rotation restricting means D is moved through the wire connected to the slider 531. On the other hand, the stopper pin 625 is actuated by bending the wire rod 627 by the pushing operation of the push button 630 , and the rotation operation of the push button 630 is used to lock the restriction release. Is to accompany.

In this embodiment, the regulation release operation means E
Is composed of a button receiver 651 and a button cover 652 which are fitted and engaged with each other in a relative manner, a push button 630 fitted and mounted on the button cover 652, and a wire holder 662 rotatably mounted on the upper surface of the push button 630. Have been.

The button receiver 651 is provided with a wire introduction hole 654 in one position regulating leg 663a and a wire fixing portion 667 in the other position regulating leg 663b. The button receiver 651 is provided with a thick portion from the inner surface of the middle portion of the leg 663b provided with the wire fixing portion 667 to the disc portion, and the wire introduction hole 654 and the wire fixing portion 667 are provided in the thick portion of the disc portion. A wire holding recess 668 is cut out so as to be orthogonal to the connecting line.

On the other hand, the button cover 652 has a button engaging recess 65 for engaging an engaging protrusion 659 of a push button 630 described later.
5 is formed on the disk, and a locking step 656 is formed one step higher adjacent to the button engaging recess 655.

The push button 630 is formed of a column-shaped piece. A wire holder 662 is attached to one end in the axial direction, a knob 669 is formed at the other end, and a pair of engaging projections 659 are formed on the peripheral surface. 662
Corresponds to the wire holding recess 668, and a knob 669
The button cover 652 is mounted on the button cover 652 so that the side projects out of the button cover 652 from the button hole 664, and the engagement protrusion 659 is vertically movably engaged with the button engagement recess 655. push button
The wire holder 630 and the wire holder 662 are assembled so as to be rotatable relative to each other by engaging a convex shaft provided on the button with a bearing hole provided on the wire holder 662. The wire holder 662 has a shape corresponding to the wire holder receiving recess 668. Is formed. The button engaging recess 655 and the locking step 656 are provided so as to correspond to the button engaging projections 659 so as to be adjacent to each other in the same direction along the periphery of the button hole 664, respectively.
While the locking step 656 is at the same height position as the engagement projection 659 when the button 630 is pushed in,
The button engaging recess 655 has at least one of the same width as the engaging protrusion 659 so that the button 630 does not rotate when the engaging protrusion 659 is engaged with the portion.

As in the case of the sixth embodiment, the restriction releasing operation means E is fitted and fixed in the button mounting concave hole 629 formed in the lever portion B1 of the operating lever B, and is pulled out from the through hole 628. The wire rod 627 is drawn into the wire introduction hole 654, passes between the wire holder 662 and the wire holder receiving recess 668, and is connected and fixed to the wire holder 667.

Therefore, in the seventh embodiment, when the button 630 of the restriction releasing operation means E is not pushed in, the stopper pin 62 of the rotation restricting means D, as in the sixth embodiment.
5 is pushed by the spring 626 and protrudes from the pin guide hole 634,
The rotation of the operating lever B is restricted by the engagement of the stopper ring 620 with the stopper portion 621. However, when the button 630 is pressed, the wire rod 662 pushes the wire rod 627 into the wire rod receiving recess 668. 668
The stopper pin 625 is pulled up by pulling the pin 625 upward from the stopper ring 620,
The engagement of the pin 625 with the stopper 621 is not released, and the rotation restriction of the operation lever B is released. Thereby, the operation lever B can be further rotated to the left from the regulation position, and the discharge water can be switched to purified water.

Since the position of the engaging projection 659 at this time is at the same height as the locking step 656, the button 630
While holding down the button, pick 669 and press button 630
When the is rotated, the engaging projection 659 is locked by the locking step 656, and the button 630 is held in the pushed-in state, and the wire rod
The stopper pin 625 is maintained in a state where the stopper pin 625 is pulled up while the state of 627 is flexed. That is, the engagement protrusion 659 and the locking step 656 constitute a lock mechanism F that fixes the restriction release state. Therefore, in this state, the mixing tap can be switched to the pure water discharge without any restriction, following the discharge of only water in the raw water discharge.

In order to return to the original state with the rotation restriction,
The button 630 may be rotated in the original direction to release the engagement projection 659 from the locking step 656. That is, if the engagement projection 659 is disengaged from the locking step 656, the button 630 is lowered by its own weight and the wire 627 is not pushed into the wire holding recess 668 by the wire holder 662. The pulling of the pin 625 due to the bending of the 627 is stopped, and the pin 625 protrudes to its original state and is again stopped.
Is engaged with the stopper portion 621. In all the embodiments described above, the operation lever is changed to the water side by rotating the operation lever to the left, and further switched to the purified water discharge. Conversely, the operation lever is rotated to the right. The change from the hot water side to the water side and the switching to the purified water discharge can be optionally performed.

[0067]

[Effect] As described above, the present invention regulates the rotation of the operating lever from the hot water side to the fully open discharge position on the water side to obtain the discharge of only water in the raw water discharge, and discharges purified water unless the safety button is operated. Since the operation lever can no longer be rotated to the position, the water side fully open discharge position in the raw water system discharge can be easily recognized, and this type of raw water is often used with the water side fully open such as storing water. Since the single-lever mixer tap is very convenient and is prevented from being inadvertently switched to purified water discharge, the life of the water purifier is prolonged. In addition, since the restriction release holding means is provided so that the rotation restriction means can be maintained in the release state, the rotation restriction release means when the usage method such that raw water and purified water are frequently discharged in a short time is used. Is maintained, it is not necessary to release the regulation each time, and the usability is improved.
