Further, the base member 6 of the toilet seat device 5 is provided with a local cleaning device (not shown) having a well-known structure and a water supply valve device 8.

  The water supply valve device 8 is connected to the downstream end of a water supply path 9 arranged behind the toilet device, and supplies cleaning water to the jet nozzle 4, the rim 3, and the local cleaning device. A (inflow passage which is a constituent element of the present invention), a second valve device B, and a branch passage unit C are provided.

<First valve device A>
The first valve device A is disposed between the downstream end of the water supply passage 9 and the upstream ends of the jet branch passage 61 and the rim branch passage 75. The first valve device A is composed of a communication member 10 and a first valve unit 20. The communication member 10 is made of synthetic resin and has a substantially cylindrical shape with the axis line directed in the left-right direction (horizontal direction), and the inside thereof communicates with a jet branch path 61 and a rim branch path 75 described later. It becomes the communicating path 11 of this.

  The left end of the communication member 10 is closed by a back wall, and the right end of the communication member 10 is opened to the outside as an attachment / detachment port 12. An inflow port 13 that protrudes downward from the lower surface wall is formed at a central position in the length direction of the communication member 10, and a jet that protrudes upward from the upper surface wall at the left end of the communication member 10. A rim outlet 14 is formed at the right end of the communication member 10 and protrudes upward from the upper wall.

  Further, a third branch path 16 that protrudes obliquely to the upper left is formed in the rear end wall so as to communicate with the communication path 11. The third branch 16 supplies cleaning water to a local cleaning device provided in the toilet seat device 5. Furthermore, a jet communication port 17 is formed at the left end of the communication member 10 so as to protrude downward from the lower wall and correspond to the jet outlet 14 in a coaxial manner.

  As shown in FIG. 5, the first valve unit 20 is obtained by integrating a first check valve 21 and a strainer 26. The first check valve 21 includes a cylindrical flow path 22, a first valve body 23, and a first return spring 24. The cylindrical flow path 22 has its axis line oriented in the vertical direction, and both its upper end surface (downstream end surface) and lower end surface (upstream end surface) are opened, and the opening edge of the upper end surface serves as a valve seat. ing. The first valve body 23 is fixed to the upper end of the first valve rod 25 in the axial direction supported in the cylindrical flow path 22 and forms a horizontal disk shape perpendicular to the axial line.

  In the first check valve 21, the first valve body 23 is always in liquid-tight contact with the valve seat by the bias of the first return spring 24, and is held in the closed state shown in FIG. When water pressure is applied to the first valve body 23 from the upstream side (lower side), the first valve body 23 moves upward (outward) of the cylindrical flow path 22 against the first return spring 24. And the 1st non-return valve 21 will be in the valve opening state shown in FIG.3 and FIG.4.

  The strainer 26 includes a cylindrical holder 27 and a filtration net 28. The cylindrical holder 27 is assembled to the lower end portion of the cylindrical flow path 22 with its axis line oriented in the vertical direction, that is, coaxially with the axis line of the cylindrical flow path 22. In the state where the first valve unit 20 is assembled, the first check valve 21 is disposed on the downstream side of the strainer 26. Further, from the upper end of the cylindrical holder 27, the upper half region of the cylindrical flow path 22 and the first valve body 23 are in a state of protruding (exposed).

  The upper end surface (end surface on the downstream side) of the cylindrical holder 27 is open and communicates with the lower end opening of the cylindrical flow path 22. The lower end of the cylindrical holder 27 is closed. The cylindrical holder 27 has a plurality of filtration holes that allow the inner peripheral side and the outer peripheral side to communicate with each other, and a filtration net 28 is attached to the inner peripheral surface of the cylindrical holder 27.

  Further, downward convex portions (not shown) are formed at the lower end portion of the cylindrical flow path 22 at intervals in the circumferential direction, and upward convex portions (not shown) are provided around the upper end portion of the cylindrical holder 27. The cylindrical holder 27 and the cylindrical shape are formed by interposing the convex portions on both sides alternately and fitting a ring (not shown) to the grooves on the outer periphery of the convex portions. The flow path 22 is assembled | attached coaxially. Therefore, if the ring is removed, the cylindrical holder 27 (strainer 26) and the cylindrical flow path 22 (first check valve 21) can be easily separated.

  The first valve unit 20 is detachably connected by coupling the upper end portion of the cylindrical holder 27 from below into a cylindrical mounting member 29 attached to the inlet 13 of the communication member 10. A connecting port 30 is formed in the cylindrical mounting member 29, and the downstream end of the water supply passage 9 is detachably connected to the connecting port 30. The water that has flowed into the cylindrical holder 27 from the water supply channel 9 through the connection port 30 is purified by removing foreign substances when passing through the filter net 28, and passes through the inner cylinder to form the cylindrical shape of the first check valve 21. It flows into the flow path 22.

  In a state where the first valve unit 20 is attached to the communication member 10, the positional relationship is such that the vertical axis of the first valve unit 20 is orthogonal to the axial direction (left-right direction) of the communication member 10. Further, the downstream end of the cylindrical flow path 22 communicates with the communication path 11 of the communication member 10, and when the first check valve 21 is closed, the first valve body 23 is outside (downward) of the communication path 11. However, when the first check valve 21 is opened, the first valve body 23 advances into the communication passage 11 and the water in the first valve device A flows into the communication member 10. It is like that.

<Second valve device B>
Similarly to the first valve device A, the second valve device B is also disposed between the downstream end of the water supply passage 9 and the upstream ends of the jet branch passage 61 and the rim branch passage 75. The second valve device B includes a communication member 10 which is a component shared with the first valve device A, and a second valve unit 40 (a functional member which is a constituent element of the present invention) accommodated in the communication member 10. Configured.

  As shown in FIG. 6, the second valve unit 40 includes a unit case 41, a rim flow control valve 47, a jet flow control valve 51, and a second check valve 53. The unit case 41 is configured by assembling the first case configuration body 41a, the second case configuration body 41b, and the third case configuration body 41c, and as a whole, is elongated in the left-right direction, that is, in the form in which the axis is directed in the left-right direction. is there.

  The first case structure 41a is made of polyphenylene sulfide resin, has a cylindrical shape as a whole, has an open left end, and is closed by a lid 42 at the right end. A communication hole 43 that communicates with the rim outlet 15 is formed in the peripheral wall of the first case structure 41a. The second case structure 41b is made of polyacetal resin and has a cylindrical shape that is symmetrical as a whole. The second case structure 41b is formed with an escape hole 44 having a shape in which the region excluding its left and right ends is vertically penetrated. The escape hole 44 has a size corresponding to the inlet 13 and is larger than the outer diameter of the first valve body 23. The third case structure 41c is made of polyphenylene sulfide resin and has a cylindrical shape penetrating in the left-right direction.

  A convex portion (not shown) that protrudes to the left is formed at the left end portion of the first case configuration body 41a with an interval in the circumferential direction, and a convex configuration that protrudes to the right at the right end portion of the second case configuration body 41b. Parts (not shown) are formed at intervals in the circumferential direction, by fitting both convex portions alternately, and fitting a ring (not shown) to the outer peripheral groove of these convex portions, The left end portion of the first case constituting body 41a and the right end portion of the second case constituting body 41b are assembled coaxially. Therefore, if the ring is removed, the first case structure 41a and the second case structure 41b can be easily separated.

  A convex portion (not shown) protruding leftward is formed at the left end portion of the second case configuration body 41b with an interval in the circumferential direction, and a convexity protruding rightward is formed at the right end portion of the third case configuration body 41c. Parts (not shown) are formed at intervals in the circumferential direction, by fitting both convex portions alternately, and fitting a ring (not shown) to the outer peripheral groove of these convex portions, The left end portion of the second case constituting body 41b and the right end portion of the third case constituting body 41c are assembled coaxially. Therefore, if the ring is removed, the second case structure 41b and the third case structure 41c can be easily separated.

  The assembled unit case 41 communicates with the inflow port 13 through the escape hole 44 and through the communication hole 43 by the right end portions of the first case structural body 41a and the second case structural body 41b. A rim case internal flow path 45 communicating with the rim outlet 15 is formed. Further, the left end portion of the second case constituting body 41b and the third case constituting body 41c communicate with the inflow port 13 through the relief hole 44, and the jet outflow port through the second check valve 53 described later. A flow path 46 in the jet case communicating with the nozzle 14 is formed. The rim case passage 45 and the jet case passage 46 are arranged coaxially.

  A rim flow control valve 47 is provided in a connection portion between the first case component 41a and the second case component 41b in the rim case flow passage 45. The rim flow control valve 47 is provided on the inner periphery of the second case component 41b between a step formed on the inner periphery of the first case component 41a and a stopper formed on the inner periphery of the second case component 41b. A sliding body 48 that moves in the left-right direction (axial direction) while sliding, a compression coil spring 49 that biases the sliding body 48 to the left and controls the flow rate according to pressure, and a sliding body 48 The elastic body 50 is mounted.

  A jet flow control valve 51 is provided at a connection portion between the second case component 41b and the third case component 41c in the jet case flow path 46. The jet flow control valve 51 is disposed on the inner periphery of the second case component 41b between a step formed on the inner periphery of the third case component 41c and a stopper formed on the inner periphery of the second case component 41b. A sliding body 48 that moves in the left-right direction (axial direction) while sliding, a compression coil spring 49 that biases the sliding body 48 to the right and controls the flow rate according to pressure, and a sliding body 48 The elastic body 50 is mounted.

  Both the elastic body 50 of the rim flow control valve 47 and the elastic body 50 of the jet flow control valve 51 are arranged so as to face the flow path formed in the sliding body 48, and the water flowing in from the inflow port 13. By elastically deforming according to the pressure, the flow path of the sliding body 48 is expanded or narrowed. The sliding body 48 moves according to the water pressure and the elastic body 50 is elastically deformed, so that the flow rate of water passing through the rim flow control valve 47 and the flow rate of water passing through the jet flow control valve 51 are substantially constant. Become.

  The sliding body 48 and the compression coil spring 49 of the rim flow control valve 47 are assembled so as to be sandwiched between the first case constituent body 41a and the second case constituent body 41b. Therefore, the rim flow control valve 47 can be removed by separating the first case component 41a and the second case component 41b so as to be separated from each other in the left-right direction. Similarly, the sliding body 48 and the compression coil spring 49 of the jet flow control valve 51 are attached so as to be sandwiched from the left and right between the second case constituent body 41b and the third case constituent body 41c. The jet flow control valve 51 can be removed by separating the case structure 41b and the third case structure 41c so as to be separated left and right.

  The second valve unit 40 is connected to the communication member 10 by being inserted into the attachment / detachment port 12 from the right side in parallel with the axial direction of the flow paths 45 and 46 in the case (that is, the axial direction of the unit case 41). It is accommodated in the passage 11. In a state where the second valve unit 40 is accommodated in the communication member 10, the outer periphery of the first case component 41a and the outer periphery of the third case component 41c are fitted to the inner periphery of the communication path 11, and the lid portion 42 is The attachment / detachment port 12 is closed. The escape hole 44 corresponds to the inlet 13, and the communication hole 43 corresponds to the rim outlet 15.

  The left end of the second valve unit 40 (the left end of the third case component 41c) is located in the vicinity of the right side of the jet outlet 14 and the jet communication port 17, and the jet outlet 14 and the jet communication port 17 Are in a state of directly facing each other. When the second valve unit 40 is removed from the communication member 10, the second valve unit 40 may be moved rightward along the axial direction and removed from the attachment / detachment port 12, contrary to the attachment.

  A pressure accumulator 52 is connected to the jet communication port 17 of the communication member 10 as a means for pumping high-pressure washing water to a jet branch path 61 described later. The pressure accumulator 52 is attached to the communication member 10 as an option when the water pressure supplied to the water supply channel 9 is low. When the water pressure is different, the flow characteristics required for the flow control valves 47 and 51 provided in the second valve unit 40 are also different. Therefore, when the pressure accumulator 52 is attached as an option, the second valve unit 40 Is replaced with another second valve unit 40 having flow control valves 47 and 51 having predetermined flow characteristics.

In a state where a jet opening / closing valve 74 described later is closed, high-pressure water is stored in the pressure accumulator 52 from the jet communication port 17, and when the jet opening / closing valve 74 is opened, the jet branch path is opened. As the water pressure in 16 decreases, the high-pressure water in the accumulator 52 is pumped into the jet branch 16.
When the rim on / off valve 78 is opened while the jet on / off valve 74 is closed, the high-pressure water in the accumulator 52 is used for the rim as the water pressure in the communication passage 11 decreases. There is a concern that it will flow out to the branch 75 side. As a countermeasure, when the pressure accumulator 52 is attached, a second check valve 53 (a check valve which is a component of the present invention) is attached to the left end portion of the second valve unit 40.

  The second check valve 53 communicates with the jet outlet 14 and the pressure accumulator 52, and can be moved in the left-right direction with respect to the support member 54 attached to the left end opening of the third case constituting body 41c. And a second return spring 56 that urges the second valve body 55 in a direction to bring the second valve body 55 into close contact with the seat surface formed on the inner periphery of the third case constituting body 41c. Yes. The support member 54 has a water passage hole (not shown) that allows water to pass therethrough. The second check valve 53 is always held in a closed state by the bias of the second return spring 56, but from the jet case inner passage 46 side (upstream side) to the second valve body 55. When the water pressure acts, the valve is opened against the bias of the second return spring 56.

<Branch unit C>
The branch path unit C is disposed on the downstream side of the first valve device A, and the communication member 10, the second valve unit 40, the pressure accumulator 52, the third branch path 16, the jet branch path 61, and the rim branch path. 75, an electric on-off valve device 66 for jets and an electric on-off valve device 77 for rims. The communication member 10, the second valve unit 40, the pressure accumulator 52, and the third branch path 16 are components supplied with the first valve device A or the second valve device B, and thus description thereof is omitted.

  As shown in FIG. 4, the jet branch 61 generally has a cylindrical shape whose axis is directed in the vertical direction (that is, a direction perpendicular to the axis of the communication member 10 and parallel to the axis of the first valve unit 20). Make. The jet branch 61 is attached to the communication member 10 so that the lower end (upstream end) of the jet branch 61 is fitted to the jet outlet 14 from above. The upstream end of the jet pipe 62 is connected to the downstream end (upper end) of the jet branch path 61 via the atmosphere release valve 80, and the downstream end of the jet pipe 62 is connected to the jet nozzle 4. . Further, the jet branch path 61 can be detached from the communication member 10. The lower end of the jet branch path 61 is formed with a valve port 63 that opens to the outer peripheral surface thereof, and the upstream side of the jet branch path 61 with respect to the valve port 63 is a primary channel 64. The downstream side of the valve port 63 is a secondary side flow path 65.

  The jet electric on-off valve device 66 includes a casing 67 that is attached to the outer periphery of the jet branch passage 61 and covers the valve port 63, a diaphragm plate 68 that is provided in the casing 67 and opens and closes the valve port 63, and the casing 67 And a solenoid 69 provided above the diaphragm plate 68 in FIG. In the casing 67, a pressure chamber 70 is formed which is located on the opposite side of the valve port 63 with the diaphragm plate 68 interposed therebetween and communicates with the primary side flow path 64 through an orifice formed in the diaphragm plate 68. .

  A return spring 71 is attached to the diaphragm plate 68 to urge the diaphragm plate 68 in the valve closing direction when the valve port 63 is opened. The casing 67 is formed with a pilot channel 72 that allows the pressure chamber 70 and the secondary channel 65 to communicate with each other. In the middle of the pilot flow path 72, a pilot valve 73 that is always kept in a closed state and is opened by energization of the solenoid 69 is provided. The jet on / off valve 74 is configured as described above.

  The pressure receiving area facing the pressure chamber 70 in the diaphragm plate 68 is larger than the pressure receiving area facing the secondary flow path 65 at the valve port 63, and the pressure chamber 70 is in the same high pressure state as the primary flow path 64 through the orifice. Therefore, when the pilot valve 73 is closed, the valve port 63 is closed by the diaphragm plate 68, and the jet on-off valve 74 is kept closed. When the solenoid 69 is energized in the closed state to open the pilot valve 73, the water in the pressure chamber 70 flows out into the secondary side passage 65 through the pilot passage 72 and flows into the pressure chamber 70. Is lower than the primary flow path 64, and the pressure from the primary flow path acting on the outer peripheral edge of the diaphragm plate 68 causes the diaphragm plate 68 to move away from the valve port 63, thereby opening the jet on-off valve 74. .

  When the pilot valve 73 is closed in the open state, the pressure in the pressure chamber 70 increases, so that the diaphragm plate 68 moves to the valve port 63 side by the urging of the return spring 71. Then, the opening degree of the valve port 63 is reduced, and the pressure in the secondary side flow path 65 is decreased. Therefore, the pressure difference between the primary side and the secondary side acting on the diaphragm plate 68 is expanded, and the diaphragm plate 68 is The port 63 is closed and the valve is closed.

  The rim branch path 75 has a cylindrical shape with the axis line directed in the vertical direction (that is, a direction perpendicular to the axis line of the communication member 10 and parallel to the axis line of the first valve unit 20). The rim branch path 75 is attached to the communication member 10 so that the lower end (upstream end) thereof is fitted to the rim outlet 15 from above. The downstream end (upper end) of the rim branch path 75 is connected to the upstream end of the rim pipe 76 via the atmosphere release valve 81, and the downstream end of the rim pipe 76 is connected to the rim 3. Further, the rim branch path 75 can be detached from the communication member 10. At the lower end of the rim branch path 75, a valve port 63 that opens to the outer peripheral surface is formed, and the upstream side of the rim branch path 75 upstream of the valve port 63 is a primary channel 64. The downstream side of the valve port 63 is a secondary side flow path 65.

  The rim electric on-off valve device 77 includes a casing 67 that is attached to the outer periphery of the rim branch path 75 and covers the valve port 63, a diaphragm plate 68 that is provided in the casing 67 and opens and closes the valve port 63, and the casing 67 And a solenoid 69 provided above the diaphragm plate 68 in FIG. The rim electric opening / closing valve device 77 and the rim branch passage 75 constitute a rim opening / closing valve 78. The structure, configuration, function, opening / closing operation and the like of the rim electric on-off valve device 77 are the same as those of the jet electric on-off valve device 66, and the rim on-off valve 78 is the same as that of the jet on-off valve 74. Therefore, the description is omitted.

  Next, the arrangement of the jet branch path 61, the rim branch path 75, the jet electric on-off valve device 66, and the rim electric on-off valve device 77 will be described. As shown in FIG. 7, the jet branch path 61, the rim branch path 75, the jet electric on-off valve apparatus 66, and the rim electric on-off valve apparatus 77 are arranged along one virtual plane 79. The virtual plane 79 is a virtual plane extending in the up-down direction and the left-right direction, and the axis line of the jet branch path 61 and the axis line of the rim branch path 75 are both located within the virtual plane 79. The jet branch path 61 and the rim branch path 75 are arranged in parallel to each other so as to be lined up on the left and right. Further, the third branch path 16, the communication member 10, and the first valve device A are also arranged along the virtual plane 79.

  Since the communication member 10 that communicates the upstream end of the jet branch path 61 and the upstream end of the rim branch path 75 accommodates the second valve unit 40 as a functional member therein, It has a predetermined length. As a result, a space is secured between the jet branch 61 and the rim branch 75 above the communication member 10 and has a sufficient width corresponding to the length of the communication member 10. Yes. In this space, an electric on-off valve device 66 for jet and an electric on-off valve device 77 for rim are arranged. Further, since the front and rear dimensions of the both electric on-off valve devices 66 and 77 are smaller than the front and rear dimensions of the both branch passages 61 and 75, the both electric on-off valve devices 66 and 77 are arranged in front and rear of the branch passages 61 and 75 in the front-rear direction. It doesn't stick out. That is, the electric on-off valve devices 66 and 77 are within the range of the arrangement area of the branch paths 61 and 75 in the front-rear direction.

  When the toilet bowl 2 of the toilet body 1 is cleaned, when a signal for instructing cleaning is input to the circuit board (not shown) of the toilet seat device 5 by a remote control operation or the like, first, the rim opening / closing valve 78 is opened. The wash water that has passed through the water supply passage 9, the strainer 26, the first check valve 21, the rim flow control valve 47, the rim case passage 45, the rim branch passage 75, and the rim pipe 76 in this order The washing water is poured from the rim 3 along the inner wall of the toilet bowl 2.

  Thereafter, the rim on-off valve 78 is closed, and immediately after that, the jet on-off valve 74 is opened, and the water supply passage 9, the strainer 26, the first check valve 21, the jet flow control valve 51, and the jet use valve. Wash water that has passed through the in-case flow path 46, the second check valve 53, the jet branch path 61, and the jet pipe 62 in this order is supplied to the jet nozzle 4 and directed from the jet nozzle 4 toward the trap portion of the toilet bowl 2. High pressure cleaning water is discharged. At the same time, the high-pressure washing water stored in the pressure accumulator 52 merges with the washing water flowing into the jet branch passage 61 from the jet case inner passage 46 and supplied to the jet nozzle 4. Water pressure is increased.

<Operation and Effect of Embodiment>
In the present embodiment, the first valve unit 20 constituting the first valve device A is configured such that the first check valve 21 and the strainer 26 are integrated. Therefore, when maintenance is to be performed on the first check valve 21 and the strainer 26 at the same time, the work for removing and attaching the first check valve 21 and the strainer 26 can be performed in one action, respectively. Excellent.

Further, since the first check valve 21 is arranged on the downstream side of the strainer 26, it is difficult for foreign matter to be caught in the first check valve 21.
Further, by separating the first check valve 21 and the strainer 26, the maintenance of the first check valve 21 and the maintenance of the strainer 26 can be performed individually, so that workability is good.

  Further, when the first check valve 21 is opened, the first valve body 23 moves into the communication path 11. The moving direction (vertical direction) of the first valve body 23 is the length direction of the communication path 11. Since the direction intersects with the (left-right direction), the flow path in the communication path 11 is not significantly narrowed by the first valve body 23. Therefore, a large flow rate of the washing water from the first check valve 21 to the jet branch path 61 and the rim branch path 75 can be secured.

  The second valve device B is configured by housing a second valve unit 40 including flow control valves 47 and 51 functioning as a constant flow valve or a constant pressure valve in the communication member 10, and the second valve unit 40 is an attachment / detachment port. 12 is inserted into and removed from the communication member 10. Here, since the attachment / detachment port 12 is formed at a position different from the inflow port 13 communicating with the water supply channel 9 and the outflow ports 14 and 15 communicating with the branch channels 61 and 75, the flow control valves 47 and 51 are removed. At this time, it is only necessary to pull out the second valve unit 40 out of the communication member 10 at the attachment / detachment port 12. That is, since the troublesome work of separating the water supply path 9 and the branch paths 61 and 75 is not required, the workability is excellent.

  Further, the jet case inner passage 46 and the rim case inner passage 45 of the second valve unit 40 are arranged so that the axes along the flow direction are arranged coaxially, and along the axial direction. The arrangement direction is a direction parallel to the insertion / removal direction of the second valve unit 40 with respect to the communication member 10. Therefore, the second valve unit 40 can have an elongated shape along the insertion / removal direction.

  Further, the unit case 41 is configured by assembling the first to third case components 41a, 41b, and 41c separated into a form in which the flow control valves 47 and 51 can be attached and detached. If 41a, 41b and 41c are separated, only the flow control valves 47 and 51 can be removed. As a result, the unit case 41 can be made common to a plurality of types of flow control valves 47 and 51 having different standards relating to the flow rate.

In view of the fact that the flow control valves 47 and 51 are provided with a movable sliding body 48, the second case constituting body 41b with which the sliding body 48 comes into sliding contact is made of polyacetal resin. Since polyacetal resin has high rigidity and self-lubricating properties, it is suitable as a material for a case structure for stably sliding the sliding body 48.
On the other hand, the first case structure 41a fitted to the attachment / detachment opening 12 is made of polyphenylene sulfide resin. However, since the polyphenylene sulfide resin is excellent in mechanical strength and rigidity, the first case structure 41a is fitted with the attachment / detachment opening 12. It is suitable as a material for the first case structure 41a that stabilizes the posture and position of the two-valve unit 40.

  In view of the fact that a pressure accumulator 52 for pumping high-pressure washing water to the jet branch path 61 is connected to the communication member 10, the second valve unit 40 includes a pressure accumulator 52 and a jet branch path. A second check valve 53 is provided so as to communicate with 61. Thereby, the high-pressure washing water pumped from the pressure accumulator 52 surely flows into the jet branch path 61 without flowing back to the jet flow control valve 51 side.

  In the branch path unit C of this embodiment, all of the jet branch path 61, the rim branch path 75, the jet electric on-off valve apparatus 66, and the rim electric on-off valve apparatus 77 are along one virtual plane 79. Has been placed. Therefore, the size of the branch path unit C in the front-rear direction orthogonal to the virtual plane 79 is suppressed to be small, and the branch path unit C is arranged in a narrow space.

  Further, the branch path unit C includes a communication member 10 that allows the upstream ends of the rim branch path 75 and the jet branch path 61 to communicate with each other, and an inflow path (first valve device) for allowing cleaning water to flow into the communication member 10. A), the communication member 10 and the inflow passage (first valve device A) are both on a virtual plane 79 common to the branch passages 61 and 75 and the electric on-off valve devices 66 and 77. Since it arrange | positions along, it can avoid the enlargement of the branch unit C resulting from providing the communicating member 10 and an inflow path, and can avoid the enlargement of the valve apparatus 8 for water supply by extension.

    In addition, the communication member 10 that allows the jet branch path 61 and the rim branch path 75 to communicate with each other has a length for accommodating the second valve unit 40 therein. A space corresponding to the communication member 10 is secured. Focusing on this point, the space corresponding to the communication member 10 was effectively used as a space for arranging the two electric on-off valve devices 66 and 77.

  Further, the jet branch path 61 can be separated from the communication member 10, and the rim branch path 75 can also be separated from the communication member 10. As described above, since the branch paths 61 and 75 and the communication member 10 are separated, maintenance of the branch paths 61 and 75 and maintenance work of the communication member 10 can be easily performed.
