As shown in fig. 5, the transmission member 315 transmits the rotation of the operation lever 33 to the movable disk 314, and rotates the movable disk 314. The power transmission member 315 includes a disc-shaped large diameter portion 3151, a cylindrical small diameter portion 3152 having a smaller diameter than the large diameter portion 3151, and a rectangular parallelepiped connecting portion 3153.
The diameter of the large diameter portion 3151 is substantially the same as the diameter of the movable disk 314. The large diameter portion 3151 is provided with three convex portions 3151a at equal intervals in the circumferential direction. The three protrusions 3151a are fitted into the three notches 3141 of the movable disk 314, respectively. The small diameter portion 3152 is symmetrically provided with two grooves 3152a extending in the axial direction. The connecting portion 3153 is provided with a lever 33. The coupling portion 3153 is provided with a groove 3153a extending in a direction substantially perpendicular to the axial direction. When the transmission member 315 is accommodated in the housing 311, the connection portion 3153 extends outside the housing 311 through the small diameter portion 3112 of the housing 311.
As shown in fig. 5, the collar 316 has a cylindrical shape, and the small diameter portion 3152 of the power transmission member 315 is fitted therein. On the inner surface of the collar 316, two protrusions 3161 extending in the axial direction are provided.

As shown in fig. 3(b) and 4, the fixing nut 32 has a cylindrical shape and has an external thread. The external thread is screwed to the internal thread of the receiving portion 21. When the fixing nut 32 is attached to the accommodating portion 21, the fixing nut 32 is fitted inside the small diameter portion 3112 of the housing 311. In addition, the fixing nut 32 contacts the large diameter portion 3111 of the housing 311 to fix the switching unit 31 in the accommodating portion 21.
The operating lever 33 is connected to the transmission member 315 and rotates the transmission member 315. As shown in fig. 3(c) and 4, the joystick 33 includes an operation portion 331 and a mounting portion 332. The user can rotate the operating lever 33 by operating the operating portion 311. The mounting portion 332 is provided with a recess 3321 having a rectangular parallelepiped shape complementary to the shape of the connecting portion 3153 of the transmission member 315. The coupling portion 3153 is embedded in the embedding concave portion 3321. Further, a convex portion 3322 is provided on the inner surface of the concave portion 3321. The projection 3322 is fitted into the groove 3153a of the transmission member 315.
In the housing 311, a power transmission member 315 to which a collar 316 is attached, a movable disk 314, and a fixed disk 312 are accommodated in this order. The cover 313 covers the first surface 312A side of the fixed disk 312. Then, the claw portion 3132 of the cover 313 is locked to the opening portion 3111a of the housing 311, thereby completing the switching unit 31.
The switching unit 31 is housed in the housing portion 21 so that the cover is on the main body portion 2 side. And, by screwing a fixing nut into the housing portion 21, the switching unit 31 is fixed to the main body portion 2. The operating lever 33 is mounted to the transmission member 315 by inserting the coupling portion 3153 of the transmission member 315 into the recess 3321 of the operating lever 33 and fitting the protrusion 3322 of the operating lever 33 into the groove 3153a of the coupling portion 3153. The projection 3322 is fitted into the groove 3153a of the transmission member 315, and thus does not fall off from the transmission member even if the operating lever 33 is axially pulled.
By rotating the lever 33, the transmission member 315 also rotates. Since the protrusion 3151a of the transmission member 315 is fitted into the notch 3141 of the movable disk 314, the movable disk 314 rotates as the transmission member 315 rotates. The movable disk 314 rotates while its first surface 314A slides on the second surface 312B of the fixed disk 312. Since the fixed disk 312 is fixed to the housing 311 together with the cover 313, the fixed disk 312 does not rotate even if the movable disk 314 rotates.
Referring to fig. 6, a raw water inflow port 3122, a shower water outflow port 3123, a shower water guide passage 3124, a straight water outflow port 3125, a straight water guide passage 3126, a purified water inflow port 3127, a purified water guide passage 3128, and a purified water outflow port 3129 of the fixed tray 312 are described.

The purified water inflow port 3127 is a through hole provided at the center of the fixed disk 312. The purified water flows through the purified water inflow port 3127 from the first surface 312A side to the second surface 312 Bce.
The purified water guide passage 3128 is provided at the second face 312B of the fixed disk 312. The purified water guide passage 3128 is a concave portion that is concave toward the first surface 312A side, and communicates with the purified water inflow port 3127. The clean water diversion passage 3128 extends radially outward from the clean water inflow port 3127 to a space between the shower water diversion passage 3124 and the clean water outflow port 3129.
The purified water outlet 3129 is a through hole provided at a position symmetrical to the raw water inlet 3122 with respect to the center of the fixed disk 312. When the switching mechanism 3 is in the purified water outflow mode, purified water flows through the purified water outflow port 3129 from the second surface 312B side to the first surface 312A side.
Referring to fig. 7, the raw water guide path 3142 and the purified water guide path 3143 of the movable disk 314 are described.
The raw water guide passage 3124 is provided in the vicinity of the periphery of the movable disk 314. The raw water guide passage 3124 is a concave portion that is concave toward the second surface 314B side, and extends while being curved in a direction substantially parallel to the outer periphery of the movable disk 314.
And a clean water diversion passage 3143 provided near the periphery of the movable disk 314. The purified water guide passage 3143 is a concave portion that is recessed toward the second surface 314B, and extends while being bent in a direction substantially parallel to the outer periphery of the movable disk 314.
3 shower water outlet mode
Referring to fig. 8 and 9, the case where shower water is discharged from the shower water outlet 23 is described.
The user operates the lever 33 to rotate the movable disk 314, as shown in fig. 9(a), to switch the position of the movable disk 314 so that the raw water inflow port 3122 and the shower water guide passage 3124 of the fixed disk 312 communicate with the raw water guide passage 3142 of the movable disk 314.
As shown in fig. 8 and 9(a), the raw water having reached the fixed disk 312 through the raw water guide passage P1 flows into one end of the raw water guide passage 3142 of the movable disk through the raw water inflow port 3122. The raw water flows from one end to the other end in the raw water guide path 3142. Thereafter, the raw water flows from the raw water guide passage 3142 of the movable disk 314 into one end of the shower water guide passage 3124 of the fixed disk 312, and flows from one end to the other end within the shower water guide passage 3124. Then, the raw water flows out from the shower water outlet 3123, as shown in fig. 8(b), passes through the shower water supply passage P3, and is discharged from the shower water outlet 23 as shower water.
As shown in fig. 9(a), when the movable plate 314 is in the shower outlet position, the straight flow water guide passage 3126 and the straight flow water outlet 3125 of the fixed plate 312 are not communicated with the raw water guide passage 3142 of the movable plate 314. Therefore, when the movable plate 314 is at the shower outlet position, the straight water is not discharged from the straight water outlet 24.
As shown in fig. 12(b), the purified water flows into the main body 2 from the purified water inlet 26, passes through the purified water diversion passage P2, and reaches the switching mechanism 3. Here, as shown in fig. 9(b), when the movable plate 314 is in the shower outlet position, the purified water guide passage 3128 of the fixed plate 312 is opposed to the flat surface portion of the first surface 314A of the movable plate 314. Therefore, the clean water flowing in from the clean water inflow port 3127 enters the clean water guide passage 3128 and is blocked by the flat surface portion of the movable disk 314. Thus, when the movable plate 314 is in the flower spray water discharge position, clean water is not discharged from the clean water outlet 27.
4 straight-flow water outlet mode
Referring to fig. 10 and 11, the case where the straight water is discharged from the straight water outlet port 24 is described.
The user operates the lever 33 to rotate the movable disk 314, as shown in fig. 11(a), to switch the position of the movable disk 314 such that the raw water inflow port 3122 and the straight water flow guide passage 3126 of the fixed disk 312 communicate with the raw water flow guide passage 3142 of the movable disk 314.
As shown in fig. 10 and 11(a), the raw water reaching the fixed disk 312 through the raw water guide passage P1 flows into one end of the raw water guide passage 3142 of the movable disk 314 through the raw water inflow port 3122. The raw water flows from one end to the other end in the raw water guide path 3142. Thereafter, the raw water flows from the raw water guide passage 3142 of the movable disk 314 into one end of the straight water guide passage 3126 of the fixed disk 312, and flows from one end to the other end within the straight water guide passage 3126. Then, the raw water flows out from the straight-flow water outlet 3125, passes through the straight-flow water supply passage P4, and is discharged as straight-flow water from the straight-flow water outlet 24 as shown in fig. 10 (b).
As shown in fig. 11(a), when the movable plate 314 is in the direct water discharging position, the shower water flow passage 3124 and the shower water outlet 3123 of the fixed plate 312 are not communicated with the raw water flow passage 3142 of the movable plate 314. Therefore, when the movable plate 314 is in the straight water outlet position, the shower water is not discharged from the shower water outlet 23.
As shown in fig. 11(b), when the movable plate 314 is in the straight water discharging position, the purified water guide passage 3128 of the fixed plate 312 is opposite to the flat surface portion of the first surface 314A of the movable plate 314. Therefore, the purified water passing through the purified water diversion passage P2 flows into the purified water inflow port 3127 of the fixed platter 312, and is blocked by the flat surface portion of the movable platter 313 after entering the purified water diversion passage 3128. Thus, when the movable plate is in the straight water discharge position, the clean water is not discharged from the clean water outlet 27.
5 purified water outlet mode
Referring to fig. 12 and 13, the case where the purified water is discharged from the purified water outlet 27 will be described.
The user operates the manipulation lever 33 to rotate the movable disk 314, as shown in fig. 13(a), to switch the position of the movable disk 314 such that the purified water guide passage 3128 and the purified water outflow port 3129 of the fixed disk 312 communicate with the purified water guide passage 3143 of the movable disk 314.
As shown in fig. 12(b) and 13(a), the purified water flowing from the water purifier X into the purified water inlet 26 flows into the purified water inlet 3127 through the purified water diversion passage P2. Purified water flows from one end to the other end of the purified water guide passage 3128 of the fixed tray 312 through the purified water inflow port 3127. Then, the purified water flows into the purified water guide passage 3143 of the movable disk 314 from the purified water guide passage 3128 of the fixed disk 312, and flows from one end to the other end in the purified water guide passage 3143. Then, the purified water flows out from the purified water outflow port 3129, passes through the purified water supply passage P5, and is discharged from the purified water outlet port 27, as shown in fig. 12 (c).
As shown in fig. 13(b), when the movable tray 314 is in the purified water discharge position, the raw water inflow port 3122 of the fixed tray 312 faces the flat surface portion of the second surface 314A of the movable tray 314. Therefore, the raw water reaching the switching mechanism 3 flows into the raw water inlet 3122 of the fixed disk 312, but is blocked by the movable disk 314. Therefore, when the movable disc 314 is at the purified water outlet position, the raw water is not discharged from the shower water outlet 23 or the straight water outlet 24.
6 characteristics
In the switching device 1 of the present invention, the shower water discharge mode, the straight water discharge mode, and the pure water discharge mode can be switched by two ceramic disks, the fixed disk 312 and the movable disk 314. The number of expensive ceramic discs is reduced, and the cost is reduced. Further, since the number of ceramic disks involved in switching the water discharge mode is two, the frictional force when the disks slide each other is reduced, and the operating torque is reduced.
Since a part of the switching mechanism 3 is combined as the switching unit 3, replacement of parts is facilitated.
