A switching lever 5 for switching the flow path and adjusting the flow rate, and a switching member 11 connected to the switching lever 5 are mounted.
[0010]
As shown in FIGS. 2 and 3, the switching member 11 is housed in a cylindrical cartridge case 6 in which an upper case 7 and a lower case 10 are vertically fitted, and is formed into a disk shape by molding using ceramic or resin as a material. As shown in FIG. 4, the fixed plate 12 is formed by penetrating a hot water inlet 13, a water discharge pipe outlet 14, and a shower outlet 15 on both sides, as shown in FIG. The inlet 13 is made to correspond to the mixing chamber in which the hot water of the main body 1 is mixed, the outlet 14 for the water discharge pipe is connected to the water discharge pipe 30, and the outlet 15 for shower is connected to the shower hose 31.
[0011]
As shown in FIG. 5, the movable plate 16 has an outer diameter smaller than that of the fixed plate 12, and the communication holes 17 are formed so as to penetrate both surfaces. Thus, the communication hole 17 allows the hot water inlet 13 of the fixed plate 12 to communicate with either the water discharge pipe outlet 14 or the shower outlet 15 and supply hot water to the water discharge pipe 30 or the shower head 32. In addition, the shape or position of the hot water inlet of the fixed plate, the outlet for the water discharge pipe, the outlet for the shower, and the communication hole of the movable plate are not particularly limited.
[0012]
As shown in FIGS. 2 and 3, a disk-shaped slider 19 is fitted into the communication hole 17 of the movable plate 16 from above through a packing 18 in a watertight manner, and is eccentric from the center on the upper surface of the slider 19. At the position, a bearing portion 20 having an opening at the top is formed, and as shown in FIG. 6, a long and narrow stopper 21 is formed projecting upward from the bearing portion 20 in the horizontal direction, and the tip 21a of the stopper 21 is a slider. 19 slightly protrudes from the outer peripheral surface.
[0013]
A cylindrical slider guide 22 fitted to the upper portion of the slider 19 is a rod-shaped lever with a pin 26 inserted into a shaft hole drilled in a horizontal direction as a fulcrum in an insertion hole 25 opened in the central vertical direction. 27 is pivotally supported, and the upper portion of the lever 27 protrudes from the slider guide 22 to fix the switching lever 5, and the flange portion 28 protrudes in the horizontal direction from substantially the middle of the protruding lever 27 to both sides. The lower end engaging portion 29 is engaged with the bearing portion 20 of the slider 19.
[0014]
Further, as shown in FIG. 7, the slider guide 22 has a plurality of groove portions 23, 23, 23 formed by notching the outer peripheral surface of the side portion in an arc shape, and the center between the groove portions 23, 23, 23. A pair of locking protrusions 24, 24 are formed so as to face each other in a symmetrical position.
[0015]
The upper case 7 of the cartridge case 6 is vertically fitted to the lower case 10 to house the switching member 11, the slider 19 and the slider guide 22, and as shown in FIG. 8, a lateral hole 8 is formed on the outer surface. In the state where the slider 19 is moved from FIG. 9 (a) to FIG. 9 (b) by the tilting operation of the switching lever 5 and the tip 21a of the stopper 21 is inserted into the horizontal hole 8, the slider 19 and the movable plate 16 is prevented from rotating, and the switching lever 5 cannot be operated in the rotating direction. Further, a pair of arcuate locking portions 9 and 9 are formed on the inner periphery of the upper case 7 so that the locking protrusions 24 of the slider guide 22 abut upon rotation to limit the rotation angle of the switching lever 5. As shown in FIGS. 10A and 10B, the locking projections 24 and 24 of the slider guide 22 are grooves 9 a and 9 a formed between the locking portions 9 and 9 of the upper case 7. It can rotate only in the above range.
[0016]
FIG. 11 shows the positional relationship of the switching member 11 when the switching lever 5 is operated. When the switching lever 5 is located in the center when viewed from the front of the faucet A, as shown in FIG. Since the hot water inlet 13 and the communication hole 17 of the movable plate 16 do not communicate with each other, the hot water is in a water stop state where water is not discharged from either the water discharge pipe 30 or the shower head 32.
[0017]
Next, when the switching lever 5 is tilted forward from the main body 1 as shown by the arrow P in FIG. 1 from the water stop state of FIG. 11A, the movable plate 16 is fixed as shown in FIG. 11B. The communicating hole 17 of the movable plate 16 communicates with the hot water inlet 13 and the water discharge pipe outlet 14 of the fixed plate 12, and hot water is supplied from the water discharge pipe 30 communicating with the water discharge pipe outlet 14. Can discharge water. In this case, as the switching lever 5 is operated in the forward direction from the water stop position, the overlapping area of the hot water inlet 13 and the water discharge pipe outlet 14 of the fixed plate 12 with respect to the communication hole 17 of the movable plate 16 increases, and the discharge from the water discharge pipe 30 is increased. The amount of water can be increased.
[0018]
Also, the slider 19 connected between the switching lever 5 and the movable plate 16 moves from FIG. 9A to FIG. 9B inside the cartridge case 6, and in FIG. Since the slider 19 is inserted into the lateral hole 8 of the case 7 and cannot be rotated, the switching lever 5 cannot be rotated from this state. That is, when the switching lever 5 is at the water discharging position from the water discharging pipe 30, the switching lever 5 cannot be rotated when the flow path is switched from the shower head 32 and the switching lever 5 is turned to the back. It is necessary to return to the water stop position shown in FIG.
[0019]
Next, when the switching lever 5 is rotated from the front water stop position to the left as shown by the arrow Q in FIG. 1, the movable plate 16 is fixed to the fixed plate as shown in FIGS. 9 (c) and 11 (c). 12, the communication hole 17 of the movable plate 16 communicates with the hot water inlet 13 and the shower outlet 15 of the fixed plate 12, and the shower hose 31 communicates with the shower outlet 15. Hot water can be discharged from the head 32. In this case, as the switching lever 5 is operated to the left from the water stop position, the overlapping area of the hot water inlet 13 and the shower outlet 15 of the fixed plate 12 with respect to the communication hole 17 of the movable plate 16 increases, and the discharge from the shower head 32 increases. The amount of water can be increased. When the switching lever 5 is tilted from the water discharge position to discharge water from the water discharge pipe 30, the slider 19 comes into contact with the inner peripheral surface of the upper case 7 as shown in FIG. 9C. Therefore, in order to switch to the water discharge from the water discharge pipe 30, it is necessary to once rotate the switching lever 5 to the right and return it to the water stop position shown in FIG. 9 (a).
[0020]
Further, the slider guide 22 connected between the switching lever 5 and the movable plate 16 has a locking projection 24 in contact with the locking portion 9 of the upper case 8 at the water stop position shown in FIG. It can be rotated only in the clockwise direction, and when the switching lever 5 is operated to the left from the water stop position on the front side, the locking protrusion 24 contacts the other locking portion 9 as shown in FIG. The rotation stops at the point of contact.
[0021]
As described above, the direction of the force applied to the operation of the switching lever differs between the faucet of the present invention when water is discharged from the water discharge pipe and when water is discharged from the shower head. That is, when the switching lever is tilted, hot water is discharged or stopped from the water discharge pipe, and when the switching lever is rotated, water is discharged or stopped from the shower head, and the switching lever is operated in the water stopping direction. Since it always stops once at the water stop position, there is no risk of incorrect operation. In this embodiment, the switching lever is tilted to discharge water from the water discharge pipe, and the switching lever is rotated to rotate water from the shower head, but the switching lever is tilted to discharge water from the shower head, You may make it perform water discharge from a water discharge pipe by rotation operation of a switching lever. In addition, the tilting operation of the switching lever may be performed by discharging the water from the water stop position to the back, and the rotating operation of the switching lever may be performed by discharging the water from the water stopping position to the right. Good.
[0022]
【The invention's effect】
According to the present invention, in a faucet with a flow path switching function that performs simultaneous water stop and flow path switching to the water discharge pipe side and the shower head side by operating the switching lever, the water discharge pipe side or the shower head from the hot water stop position switching the flow path to the side, have each row in different operations of tilting and rotation of the water stop position of the switching lever, the switching lever is unrotatable when the water discharge by tilting to one direction from the water stop position, waterproofing Since it is impossible to tilt when water is discharged by rotating from one position to the other, when the switch lever is operated in the water stopping direction from the hot water discharging state, it always stops once at the water stopping position, and the water stopping operation is performed quickly and reliably. Can do.
[0023]
Also, if the switch lever is operated in the direction of water stoppage from the water discharge state from the water discharge pipe or shower head, the water stop state is always once, and if the switch lever is operated as before, the water discharge flow path is switched through the water stop position. Therefore, there is no fear that hot water will be discharged against the user's intention, and it can be used safely.
[0024]
In addition, the switching lever cannot be turned to the left or right when water is discharged from the water stop position by tilting operation, and cannot be tilted up or down when water is discharged from the water stopping position by rotation operation. If the operation is not performed, the water discharge direction cannot be switched, and the water discharge flow path is not switched by unconsciously operating the switching lever, so that erroneous water discharge can be reliably prevented.
