  Hereinafter, with reference to an accompanying drawing, an embodiment of a flush toilet which this application discloses is described in detail. In addition, this invention is not limited by embodiment shown below.

  First, the overall configuration of the flush toilet 1 will be described with reference to FIG. FIG. 1 is a schematic side sectional view showing a flush toilet 1.

  In FIG. 1, for convenience of explanation, a three-dimensional orthogonal coordinate system including a Z-axis with a vertically upward direction as a positive direction is illustrated. Note that the orthogonal coordinate system may be illustrated in other drawings.

  The Cartesian coordinate system defines the positive view of the X axis as the “right side”, the negative view of the X axis as the “left side”, the positive direction of the X axis as the right side, and the negative direction of the X axis as the left side. is doing. Further, the orthogonal coordinate system defines the front view of the Y axis as “front”, the positive direction of the Y axis as front (front), and the negative direction of the Y axis as rear (rear). The orthogonal coordinate system defines the positive direction of the Z axis as the upper side (upward) and the negative direction of the Z axis as the lower side (lower). For this reason, in the following description, the X-axis direction may be referred to as the left-right direction, the Y-axis direction may be referred to as the front-rear direction, and the Z-axis direction may be referred to as the up-down direction.

  As shown in FIG. 1, the flush toilet 1 includes a toilet body 2 and a wash water tank device 3 that stores wash water used in the toilet body 2. The toilet body 2 is installed on the floor surface of the toilet room, and the flush water tank device 3 is installed on the upper part of the toilet body 2. The toilet body 2 is not limited to a floor-standing type, but may be a wall-mounted type. Further, the washing water tank device 3 may be installed in a place away from the toilet body 2.

  The toilet body 2 has a bowl portion 21 that receives filth, a water conduit 22 that guides wash water supplied from the wash water tank device 3 to the bowl portion 21, and an inlet connected to a lower portion of the bowl portion 21. And a drain trap conduit 23 for discharging the filth to a drain pipe (not shown). The drain trap line 23 constitutes a trap part.

  In the bowl portion 21, a jet water outlet 24 that discharges the cleaning water toward the inlet of the drain trap pipe 23, and the cleaning water is discharged from the rim portion 25 to form a swirling flow of the cleaning water in the bowl portion 21. A rim spout 26 is formed. The water conduit 22 guides the cleaning water supplied from the cleaning water tank device 3 to the jet outlet 24 and the rim outlet 26.

  The drain trap pipe 23 includes an ascending path portion that extends upward from the inlet, and a descending path portion that extends downward from the end of the ascending path portion and is connected to the drain pipe. Washing water for forming a water-sealed state is stored from the bowl portion 21 to the rising path portion of the drain trap pipe 23. In the following, the cleaning water stored in the ascending path portion of the bowl portion 21 and the drain trap pipe 23 is referred to as “reserved water”.

  In the case of discharging the filth, the flush toilet 1 first performs rim water supply for discharging the rinsing water from the rim spout 26 and cleans the bowl portion 21 while collecting the filth around the center of the bowl portion 21. Perform the process. Next, the flush toilet 1 discharges wash water from the jet outlet 24 to efficiently generate a siphon action, while draining the filth in the bowl portion 21 using the siphon action. A discharge process is carried out to draw in and discharge. Next, the flush toilet 1 performs a sealing process so that the rim water is supplied from the rim spout 26 and the water level of the stored water becomes the predetermined level. That is, in the sealing water process, sealing water is formed by the cleaning water.

  As described above, the flush toilet 1 discharges filth by performing a plurality of steps. The flush toilet normally controls a plurality of steps and the flow rate of the washing water in the plurality of steps by a controller (not shown). In a plurality of processes, the next process may be started before the previous process is completed.

  The flush toilet 1 has a washing mechanism at the time of a power failure for discharging the filth at the time of a power failure because the controller cannot execute a plurality of processes and discharge the filth at the time of a power failure. In a conventional flush toilet, during a power failure, for example, the user operates the operation lever while switching the operation direction of the operation lever during power failure (hereinafter referred to as “operation lever”), thereby providing the above-described water supply process, The discharging process and the sealing process can be performed in the same manner as normal.

  However, in the conventional flush toilet, the user operates the operation lever a plurality of times at predetermined intervals, so that a plurality of normal processes are executed during a power failure. For example, the conventional flush toilet performs the water supply process by rotating the operation lever in one direction from the initial position for a first predetermined time, and then the operation lever is moved in the other direction opposite to the one direction. 2 The drainage process is executed by rotating for a predetermined time. And the conventional flush toilet performs the water sealing process by rotating the operation lever in one direction for a third predetermined time after the draining process.

  In this way, in order for the user to manually operate the operating lever to perform cleaning in multiple steps at normal times, the user must adjust the operating direction and operating time of the operating lever. It was difficult to perform the same cleaning as in the above.

  The flush toilet 1 according to the present embodiment facilitates a washing operation during a power failure. Below, the flush toilet 1 which concerns on this embodiment is demonstrated in detail.

  Accordingly, the plate push-up portion 42 rotates with the push plate 41 and can move in the left-right direction with respect to the operation lever 40 together with the push plate 41.

  A compression coil spring 61 is disposed around the pin 50 c between the attachment portion 58 and the operation lever 40. The plate push-up portion 42 and the push plate 41 are urged toward the front side by the compression coil spring 61. One end of the compression coil spring 61 is locked to the attachment portion 58, and the other end of the compression coil spring 61 is locked to the operation lever 40.

  The compression coil springs 54a and 54b and the compression coil spring 61 are disposed on the opposite side to the operation lever 40 (see FIG. 13), and the compression coil springs 54a and 54b connect the push plate 41 and the plate push-up portion 42 to each other. The compression coil spring 61 biases the push plate 41 and the plate push-up portion 42 toward the front side.

  The spring constants of the compression coil springs 54a, 54b, and 61 are determined when the push plate 41 and the plate push-up portion 42 are not pushed up by the plate shifting portion 12, for example, when the operation lever 40 is in the initial position, When the lever 40 returns from the operation start position to the initial position, the plate push-up portion 42 and the push plate 41 are set to be urged to the back side.

  The arm 59 protrudes from the radially inner end of the mounting portion 58 toward the near side, and is formed in an L shape. The arm 59 is inserted into the hole 30 b of the first support portion 15. A sliding portion 59a is formed at the front end of the arm 59 toward the back side. The sliding part 59a is formed in a spherical shape. When the plate pushing-up portion 42 is not pushed up to the near side, the sliding portion 59a abuts against the sliding groove 30c, so that the movement of the plate pushing-up portion 42 and the push plate 41 to the back side is restricted. .

  The plate shifting portion 12 is rotatably attached to the second support portion 16 via the attachment portion 68. The plate shifting portion 12 includes a case 65, a protruding portion 66, and a torsion coil spring 67. The plate shifting unit 12 constitutes a retracting unit.

  The case 65 has an annular shape, has an opening 65 a formed on the second support portion 16 side, and accommodates the torsion coil spring 67. On the outer peripheral wall of the case 65, when the operation lever 40 is rotated from the initial position to the operation start position, a protrusion 65b that contacts the stopper 17c and restricts the rotation of the plate shifting portion 12 is formed.

  When the plate shifter 12 rotates from the initial position of the plate shifter 12, the plate shifter 12 is biased by the torsion coil spring 67 toward the initial position of the plate shifter 12. The initial position of the plate shifting portion 12 is a position where the protruding portion 66 can contact the tapered surface 57 a of the push-up portion 57 when the operation lever 40 is rotated from the initial position to the operation start position.

  The protruding portion 66 is formed to protrude from the surface of the plate shifting portion 12 toward the front side. When the operation lever 40 is rotated from the initial position toward the operation start position, the taper surface 66a that slides with the taper surface 57a of the plate push-up portion 42 and the slide of the plate push-up portion 42 are formed on the surface of the protrusion 66. A moving surface 57b and a sliding surface 66b that slides are formed.

  The switch unit 13 includes a rim switch 13a and a zette switch 13b. The rim switch 13a and the zette switch 13b are arranged side by side in the front-rear direction. That is, the switch unit 13 is a vertical switch in which the rim switch 13a and the zette switch 13b are arranged in the front-rear direction. The rim switch 13a is disposed behind the zette switch 13b.

  The rim switch 13a is a mechanical switch that discharges cleaning water from the rim spout 26 when pressed by the first rim switch pressing portion 51a and the second rim switch pressing portion 51b. The switch 13b for a jet is a mechanical switch that discharges cleaning water from the jet outlet 24 when pressed by the switch pressing part 51c for the jet.

  The deceleration part 14 is a governor. The deceleration unit 14 is rotated at a preset rotation speed with respect to the urging force of the spiral spring 47 when the operation lever 40 is rotated from the initial position to the operation start position by manual operation and the operation lever 40 is released. The braking force is generated so that the operation lever 40 returns to the initial position.

  The speed reduction part 14 is rotatably supported by the second flange 32 of the first support part 15. The speed reduction part 14 includes a first gear 14a that meshes with a gear 44a formed in a circular part 44 of the operation lever 40, a second gear 14b that has more teeth than the first gear 14a, and a bar balance 14c. For example, the second gear 14 b meshes with an internal gear (not shown) provided in the case 5.

  The speed reduction unit 14 is not limited to the above-described configuration, and the operation lever 40 is operated against the urging force of the spiral spring 47 when the operation lever 40 is rotated to the operation start position and the operation lever 40 is released. The braking force may be generated so that 40 returns to the initial position at a preset rotational speed.

  In the power failure cleaning mechanism 4, by adjusting the circumferential length of each of the switch pressing portions 51 a to 51 c and the rotation speed when the operation lever 40 returns to the initial position, the flow rate of cleaning water in each step, that is, The sequence of steps can be adjusted and controlled.

  Next, the operation of the power failure cleaning mechanism 4 will be described with reference to FIGS. In FIGS. 9 to 18, a part of the configuration is omitted for explanation.

FIG. 17A is a diagram (No. 2) illustrating a state where the first rim switch pushing portion 51a pushes the rim switch 13a. FIG. 17B is a diagram illustrating a state in which the zette switch pressing portion 51c has pushed the zette switch 13b. FIG. 17C is a diagram illustrating a state where the second rim switch pressing portion 51b has pressed the rim switch 13a. FIG. 18 is a partial rear view (No. 5) of the power failure cleaning mechanism 4 according to the first embodiment.

  In the power failure cleaning mechanism 4, when the operation lever 40 is not operated and is in the initial position, as shown in FIG. 9, the plate pushing-up portion 42 is separated from the plate shifting portion 12, and the plate pushing-up portion 42 The part 42 cannot be pushed upward. The switches 13a and 13b are not pushed by the plate push-up unit 42. The plate shifting portion 12 is at the initial position of the plate shifting portion 12.

  When the operation lever 40 is rotated from the initial position toward the operation start position, the tapered surface 57a of the plate push-up portion 42 comes into contact with the tapered surface 66a of the protruding portion 66 of the plate shifting portion 12 as shown in FIG. . When the operation lever 40 is further rotated while the tapered surfaces 57a and 66a are in contact with each other, the plate shifting portion 12 moves the plate against the urging force of the torsion coil spring 67 as shown by an arrow in FIG. It rotates from the initial position of the part 12.

  When the operation lever 40 is further rotated toward the operation start position, the projection 65b (see FIG. 8) of the plate shifting portion 12 comes into contact with the stopper 17c (see FIG. 7), and the rotation of the plate shifting portion 12 is restricted. The When the operation lever 40 is further rotated toward the operation start position, the plate pushing-up portion 42 rides on the protruding portion 66 of the plate shifting portion 12 and is pushed up toward the front side as indicated by an arrow in FIG. After riding on the protruding portion 66 of the plate shifting portion 12, the plate pushing-up portion 42 rotates together with the operation lever 40 while sliding the sliding surface 57b on the sliding surface 66b of the protruding portion 66 of the plate shifting portion 12. .

  Further, as the plate push-up portion 42 is pushed up toward the front side, as shown in FIG. 13, the push plate 41 is pushed up against the urging force of the compression coil springs 54a and 54b.

  When the push plate 41 is pushed up to the near side, the switch pushing portions 51a to 51c of the push plate 41 are pushed up to the near side from the switches 13a and 13b. In this state, a gap is formed between the switch pressing portions 51a to 51c and the switches 13a and 13b in the left-right direction. When the operation lever 40 is rotated, the switch pressing portions 51a to 51c pass through the front side of the switches 13a and 13b in a state where gaps are formed between the switches 13a and 13b. Therefore, each switch 13a, 13b is not pushed by each switch pushing part 51a-51c.

  That is, when the operation lever 40 is rotated from the initial position to the operation start position, the plate shifter 12 causes the switches 13a and 13b to operate by retracting the switch pushers 51a to 51c to the near side. To prevent.

  As described above, when the operation lever 40 is rotated from the initial position to the operation start position, the switch pressing portions 51a to 51c do not contact the switches 13a and 13b, and the switches 13a and 13b are pressed. There is no.

  After the operation lever 40 is further rotated toward the operation start position and the switch pressing portions 51a to 51c pass the front side of the switches 13a and 13b, the sliding surface 57b of the plate pushing-up portion 42 is moved to the plate shifting portion. 12 does not slide on the sliding surface 66b of the protruding portion 66. As a result, the plate shifting portion 12 rotates as indicated by the arrow in FIG. 14 by the urging force of the torsion coil spring 67.

  Further, the push plate 41 (see FIG. 13) and the plate push-up portion 42 move to the back side as shown by arrows in FIG. 15 by the urging force of the compression coil springs 54a and 54b (see FIG. 13).

  As shown in FIG. 13, a compression coil spring 61 is provided between the mounting portion 58 of the plate push-up portion 42 and the operation lever 40, and the push plate 41 and the plate push-up portion 42 move to the back side. At this time, the compression coil spring 61 contracts to apply a braking force. Therefore, it is possible to suppress the plate push-up portion 42 from being vigorously moved to the back side by the urging force of the compression coil springs 54a and 54b, and it is possible to suppress the deterioration of the cleaning mechanism 4 upon power failure.

  When the user releases the operation lever 40 after the operation lever 40 is rotated to the operation start position and the operation lever 40 is released, the operation lever 40 is moved toward the initial position by the biasing force of the spiral spring 47. Rotate. The operating lever 40 is rotated by adjusting the rotational speed to the initial position by the speed reducing unit 14.

  When the operation lever 40 rotates toward the initial position, the push plate 41 rotates together with the operation lever 40. Then, as shown in FIGS. 16 and 17A, the first rim switch pushing portion 51a pushes the rim switch 13a, and the cleaning process is executed. The cleaning process is executed while the first rim switch pressing portion 51a is pressing the rim switch 13a.

  The circumferential length of the first rim switch pusher 51a and the rotation speed of the operation lever 40 are set so that the flow rate of the cleaning water discharged from the rim water spouting port 26 in the cleaning process is equal to the normal flow rate. Is set.

  Further, when the operation lever 40 rotates toward the initial position, the first rim switch pushing portion 51a is separated from the rim switch 13a, and as shown in FIG. 17B, the zette switch pushing portion 51c pushes the zette switch 13b. The pushing and discharging process is executed. The discharging process is executed while the switch switch 51c for the jet is pressing the switch 13b for the jet.

  The circumferential length of the switch pressing portion 51c for the jet and the rotational speed of the operation lever 40 are set so that the flow rate of the cleaning water discharged from the jet water spouting port 24 in the discharging process is equal to the normal flow rate. ing.

  Further, when the operation lever 40 is rotated toward the initial position, the zette switch push portion 51c is separated from the zette switch 13b, and the second rim switch push portion 51b pushes the rim switch 13a as shown in FIG. 17C. The sealing process is performed. The sealing step is executed while the second rim switch pushing portion 51b is pushing the rim switch 13a.

  The circumferential length of the second rim switch pushing portion 51b and the rotation speed of the operation lever 40 are such that the flow rate of the cleaning water discharged from the rim water spouting port 26 in the sealing process is equal to the normal flow rate. Is set to

  As described above, when the operation lever 40 is released after the operation lever 40 is rotated to the operation start position, the cleaning process, the draining process, and the water sealing process are automatically executed. Further, the flow rate of the cleaning water in each process is controlled by a mechanical operation by the power failure cleaning mechanism 4.

  When the operation lever 40 rotates toward the initial position, even if the plate shifting portion 12 rotates toward the initial position of the plate shifting portion 12, as shown in FIG. The portion 66 abuts on the outer peripheral wall of the push-up portion 57 of the plate push-up portion 42, and the operation lever 40 is not prevented from rotating toward the initial position.

  Further, for example, when the plate shifting portion 12 returns to the initial position of the plate shifting portion 12 by the urging force of the torsion coil spring 67 before the operation lever 40 rotates toward the initial position, the plate shifting portion 12 The protrusion 66 is pushed by the push-up portion 57 of the plate push-up portion 42 and rotates in the direction indicated by the arrow in FIG. Therefore, the operation lever 40 is not prevented from rotating toward the initial position.

  The power failure cleaning mechanism 4 automatically executes a plurality of processes by operating the operation lever 40 once by manual operation at the time of power failure. Thus, the flush toilet 1 can easily perform a washing operation without causing the user to perform a complicated operation at the time of a power failure.

  Moreover, the cleaning mechanism 4 at the time of a power failure automatically performs a cleaning process, a drainage process, and a sealing process by operating the operation lever 40 once by a manual operation at the time of a power failure. Thereby, the flush toilet 1 can perform the same washing | cleaning as usual at the time of a power failure, without making a user perform complicated operation.

  For example, if a user starts a plurality of processes while the operation lever 40 is being rotated from the initial position, the flow rate of the cleaning water changes according to the operation time of the user's operation lever, and there is a risk that dirt will not be discharged. .

  On the other hand, the power failure cleaning mechanism 4 starts a plurality of steps after the operation lever 40 is rotated from the initial position to the operation start position and the operation lever 40 is released. Thereby, flush toilet 1 can suppress that the flow volume of washing water changes by a user's operation, can discharge filth like normal time, and performs washing similar to normal time. be able to.

  The power failure cleaning mechanism 4 controls the flow of cleaning water discharged from the rim spout 26 in the cleaning process and the sealing process, and the flow of cleaning water discharged from the jet spout 24 in the discharge process. The process and the sealing process are automatically executed. Thereby, even during a power outage, filth can be discharged in the same way as during normal times.

  The power failure cleaning mechanism 4 biases the operation lever 40 by a spiral spring 47 in a direction to return the operation lever 40 from the operation start position to the initial position. Thereby, the operation lever 40 can be automatically returned to the initial position.

  When the operation lever 40 is rotated from the initial position to the operation start position, the power failure cleaning mechanism 4 pushes up the switch pressing portions 51a to 51c to the near side, and the switch pressing portions 51a to 51c and the switches 13a and 13b. Create a gap between them. Thereby, when the operation lever 40 is rotated from the initial position to the operation start position, it is possible to prevent the switches 13a and 13b from being pressed.

  The deceleration unit 72 is attached to the rotation shaft unit 76, and when the operation lever 75 is rotated to the operation start position and released, the reduction unit 72 biases the rotation unit 71 toward the initial position by a spring (not shown). A braking force is generated so as to return to the initial position at a preset rotational speed.

  In the power failure cleaning mechanism 4, the length of each switch pushing portion 77 a to 77 c, the shape of each notch 80 to 82, the rotation speed when the operation lever 75 returns to the initial position, and the like are adjusted. The flow rate of the washing water, that is, the sequence of each process can be adjusted and controlled.

  Next, the operation of the power failure cleaning mechanism 4 according to the second embodiment will be described with reference to FIGS. 24A to 32C.

  “A”, “B”, and “C” attached to the figure numbers in FIGS. 24A to 32C correspond to the AA cross section, the BB cross section, and the CC cross section in FIG. For example, FIG. 24A is a cross-sectional view taken along line AA in FIG. 23 (part 1), FIG. 24B is a cross-sectional view taken along line BB in FIG. 23, and FIG. It is sectional drawing (the 1).

  24A to 32C, the same drawing number, for example, “FIGS. 24A to 24C”, indicates that each of the cross sections (the AA cross section, the BB cross section, the CC cross section) at the same position of the operation lever 75. Cross section).

  When the operation lever 75 (see FIG. 23) is in the initial position, as shown in FIGS. 24A to 24C, the switch pushing portions 77a to 77c are not in contact with the switches 13a and 13b, and the switches 13a and 13b are not pushed.

  When the operation lever 75 is rotated from the initial position toward the operation start position, the second rim switch pushing portion 77b rotates and contacts the upper end of the rim switch 13a. The second rim switch pushing portion 77b is rotatable relative to the operation lever 75 around the rotation axis of the shaft portion 86, and is restricted from rotating in the direction opposite to the rotation direction of the operation lever 75. Not. Therefore, as shown in FIG. 25A, the second rim switch pushing portion 77b rotates toward the back wall 81d around the rotation axis of the shaft portion 86 in a state of being in contact with the upper end of the rim switch 13a. Accordingly, the rim switch 13a is not pushed by the second rim switch pushing portion 77b.

  Further, as shown in FIG. 25C, the zette switch pushing portion 77c rotates and contacts the upper end of the zette switch 13b. Similarly to the second rim switch pushing portion 77b, the zet switch pushing portion 77c can rotate relative to the operation lever 75, and the rotation of the operation lever 75 in the direction opposite to the rotation direction is restricted. Not. Therefore, the zet switch 13b is not pushed by the zet switch pushing portion 77c.

  As shown in FIG. 25B, the first rim switch pushing portion 77a is not in contact with the rim switch 13a.

  When the operation lever 75 is further rotated from the initial position toward the operation start position, as shown in FIG. 26B, the first rim switch pushing portion 77a rotates and contacts the upper end of the rim switch 13a. The first rim switch pushing portion 77a is rotatable relative to the operation lever 75, and rotation in the direction opposite to the rotation direction of the operation lever 75 is not restricted. Therefore, the rim switch 13a is not pushed by the first rim switch pushing portion 77a.

  Further, the shaft portion 86 of the second rim switch pushing portion 77 b rotates together with the operation lever 75. The distal end side of the second rim switch pushing portion 77 b is in contact with the upper end of the rim switch 13 a and rotates relative to the rotation of the operation lever 75 around the rotation axis of the shaft portion 86. Therefore, the contact position of the second rim switch pushing portion 77b with the upper end of the rim switch 13a changes, and comes into contact with the upper end of the rim switch 13a on the distal end side as shown in FIG. 26A. The rim switch 13a is not pushed by the second rim switch pushing portion 77b.

  As described above, when the operation lever 75 is rotated toward the operation start position, the contact position between the second rim switch pushing portion 77b and the upper end of the rim switch 13a gradually becomes the second rim switch. It moves to the front end side of the pushing portion 77b.

  Similarly, as shown in FIG. 26C, the zette switch pushing portion 77c comes into contact with the upper end of the zette switch 13b on the tip side. The zette switch 13b is not pushed by the zette switch pushing portion 77c.

  When the operation lever 75 is further rotated toward the operation start position, the contact position between the second rim switch pushing portion 77b and the upper end of the rim switch 13a is the tip of the second rim switch pushing portion 77b. As a result, the tip of the second rim switch pushing portion 77b will not come into contact with the upper end of the rim switch 13a.

  As a result, the second rim switch pushing portion 77b rotates toward the support wall 81c around the rotation axis of the shaft portion 86 by its own weight, and comes into contact with the support wall 81c as shown in FIG. 27A. Since the front end face 13c of the rim switch 13a is tapered, the second rim switch pushing portion 77b rotates without pushing the rim switch 13a.

  In addition, as shown in FIG. 27B, the first rim switch pushing portion 77a is in contact with the upper end of the rim switch 13a at the tip side of the first rim switch pushing portion 77a. In addition, as shown in FIG. 27C, the contact position of the switch pressing portion 77c for the jet with the upper end of the switch 13b for the jet is the tip side of the switch pressing portion 77c for the jet. Even in these states, the rim switch 13a is not pushed by the first rim switch pushing portion 77a, and the zette switch 13b is not pushed by the zette switch pushing portion 77c.

  When the operation lever 75 is further rotated toward the operation start position, the zette switch pushing portion 77c does not come into contact with the upper end of the zette switch 13b, and the zette switch pushing portion 77c is caused by its own weight. It rotates around the rotation axis and comes into contact with the support wall 82c. Similarly, the first rim switch pushing portion 77a does not contact the upper end of the rim switch 13a, and the first rim switch pushing portion 77a rotates around the rotation axis of the shaft portion 85 by its own weight. , Abuts against the support wall 80c.

  As described above, when the operation lever 75 is rotated to the operation start position, the second rim switch pushing portion 77b contacts the support wall 81c as shown in FIG. 28A, and as shown in FIG. The 1-rim switch pushing portion 77a contacts the support wall 80c. Further, as shown in FIG. 28C, the zette switch push portion 77c abuts on the support wall 82c.

  When the operation lever 75 is released after the operation lever 75 is rotated to the operation start position, the rotation unit 71 rotates toward the initial position while the rotation speed is adjusted by the speed reduction unit 72.

  When the operation lever 75 rotates toward the initial position, as shown in FIG. 29B, the first rim switch pushing portion 77a is supported by the support wall 80c on the lower side, that is, the downward movement is supported by the support wall 80c. In this state, the rotation with the operation lever 75 makes contact with the front end face 13c of the rim switch 13a.

  As shown in FIG. 29A, the second rim switch pushing portion 77b rotates together with the operation lever 75 in a state where the lower rim switch pushing portion 77b is supported by the support wall 81c. Further, as shown in FIG. 29C, the zette switch pushing portion 77c rotates together with the operation lever 75 in a state where the lower portion is supported by the support wall 82c.

  When the operation lever 75 further rotates toward the initial position, the first rim switch pushing portion 77a rotates with the lower portion being supported by the support wall 80c. Therefore, as shown in FIG. 30B, the rim switch 13a is It is pushed by the first rim switch pushing portion 77a. Thereby, a cleaning process is performed. The cleaning process is executed while the rim switch 13a is being pushed by the first rim switch pushing portion 77a.

  The second rim switch pushing portion 77b does not contact the rim switch 13a as shown in FIG. 30A. Further, as shown in FIG. 30C, the zette switch pushing portion 77c abuts against the front end face 13d of the zette switch 13b with the lower portion supported by the support wall 82c.

  Further, when the operation lever 75 rotates toward the initial position, the first rim switch pushing portion 77a rotates with the lower side supported by the support wall 80c, as shown in FIG. 31B, and the rim switch 13a. The cleaning process is completed because the front end surface 13c is not contacted.

  Further, since the zette switch pushing portion 77c rotates with the lower portion being supported by the support wall 82c, as shown in FIG. 31C, the zette switch 13b is pushed by the zette switch pushing portion 77c. Thereby, a discharge process is performed. The discharging process is executed while the zette switch 13b is being pushed by the zette switch pushing portion 77c.

  Further, as shown in FIG. 31A, the second rim switch pushing portion 77b contacts the front end surface 13c of the rim switch 13a in a state where the lower rim switch push portion 77b is supported by the support wall 81c.

  Further, when the operation lever 75 is rotated toward the initial position, the zette switch pushing portion 77c is rotated with the lower portion supported by the support wall 82c as shown in FIG. 32C, and the front end face of the zette switch 13b. 13d is not contacted, and the discharging process ends.

  Further, since the second rim switch pushing portion 77b rotates with the lower side being supported by the support wall 81c, the rim switch 13a is pushed against the second rim switch pushing portion 77b as shown in FIG. 32A. It is. Thereby, a sealing process is performed. The sealing process is executed while the rim switch 13a is being pushed by the second rim switch pushing portion 77b. As shown in FIG. 32B, the first rim switch pushing portion 77a rotates in a state where the lower rim switch push portion 77a is supported by the support wall 80c.

  Further, when the operating lever 75 rotates toward the initial position, the second rim switch pushing portion 77b rotates with the lower portion supported by the support wall 81c and does not contact the front end surface 13c of the rim switch 13a. Then, the sealing process is finished.

  When the operation lever 75 is operated from the initial position to the operation start position, the power failure cleaning mechanism 4 rotates the switch push portions 77a to 77c relative to the rotation of the operation lever 75 to retract. Thereby, when the operation lever 75 is rotated from the initial position to the operation start position, it is possible to prevent the switches 13a and 13b from being pressed.

  Further, the power failure cleaning mechanism 4 regulates the relative rotation of the switch pressing portions 77a to 77c with respect to the rotation of the operation lever 75 when the operation lever 75 rotates from the operation start position toward the initial position. The washing process, the draining process, and the sealing process can be automatically executed.

  Note that the plurality of processes is not limited to the cleaning process, the discharging process, and the sealing process. For example, the plurality of steps may be a step of discharging cleaning water from different rim spouts.

  Further, between the cleaning process and the sealing water process, cleaning water having a smaller flow rate than that of the cleaning process may be discharged from the rim spout 26.

  Further effects and modifications can be easily derived by those skilled in the art. Thus, the broader aspects of the present invention are not limited to the specific details and representative embodiments shown and described above. Accordingly, various modifications can be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.
